By the way, the prior arts described in Patent Document 1 and Patent Document 2 and the like disclose a state in which the hopper is protruded from the hopper of the spraying device mounted on the bed of the vehicle to the rear of the bed (in the direction in which the deicing agent is sprayed). The fall (supply) of the deicing agent in the hopper onto a rotating disk disposed close to the road surface is performed by a conveyor or a screw provided in the front-back direction of the bottom of the hopper. Side).
For this reason, the conventional spraying apparatus has a problem that not only the structure of the entire apparatus is complicated and the cost is increased, but also a failure is easily caused. Further, there has been a problem in terms of handleability, for example, the entire apparatus becomes considerably heavy, and a large amount of labor is required for operations such as loading and unloading on a vehicle carrier.

  The present invention has been conceived as an example of an object to cope with the above-described conventional circumstances, and a spraying device that drops a sprayed object on a rotating disk and sprays the rearward of a traveling vehicle by rotation of the rotating disk. In addition to simplifying the overall structure of the device, reducing costs and improving ease of handling, it is possible to spray the antifreeze toward the rear of the running vehicle efficiently and efficiently. It is to make.

  In order to solve the above-mentioned problem, in the spraying device according to the present invention, means having at least the following configuration is taken.

A scatter device that drops a scattered object on a rotating disk, and scatters toward a rear side of a vehicle traveling by rotating the rotating disk, a hopper that stores the scattered object, and a scatterer including the rotating disk, wherein the hopper, said front wall located in the traveling direction of the vehicle is inclined toward the bottom of the side wall surface after positioned on the rear side of the vehicle, provided with a discharge chute of the spraying material to the bottom The spraying unit includes the rotating disk having a plurality of blade members, and an arc-shaped spraying guard member that circumferentially covers the outer periphery of the rotating disk, and intermittently intersperses the position below the front wall surface of the hopper. It is characterized by having a hammer mechanism for hitting from outside .
Further, the rotating disk is disposed at an obliquely lower position of the discharge drop port, and the falling position of the scattered object from the discharge drop port is closer to the traveling direction of the vehicle than the disk axis, The scatter guard member is disposed on the outer periphery of the disk in the rotation direction of the rotating disk, at a predetermined angular range in the circumferential direction with respect to the first axis straight line along the traveling direction passing through the disk axis of the rotating disk, The blade member is formed to have a length corresponding to the radius of the rotating disk, and has a base point at an intersection with a second axial straight line in the diameter direction passing through the disk axis of the rotating disk at one end located on the outer peripheral side of the disk. The other end is disposed on the rotating disk at a predetermined inclination angle with respect to the second axis straight line so as to be separated from the second axis straight line in the rotation direction of the rotating disk.

Here, the angle of the spray guard member with respect to the first axis straight line in the rotation direction of the rotating disk is 5 ° to 40 °, preferably 10 ° to 30 °, particularly preferably 25 °, The inclination angle of the blade member on the rotating disk with respect to the second axis straight line is 20 ° to 50 °, preferably 35 ° to 45 °, and particularly preferably 40 °.

Then, the scattered material that has slipped down to the discharge fall port falls on a rotating disk disposed diagonally below the discharge drop port (a position lower than the height of the vehicle bed), and travels by rotating the rotating disk. Sprayed toward the rear of the vehicle.
At this time, the scattered material in the hopper falls from the discharge / fall port onto the rotating disk located closer to the traveling direction of the vehicle than the rotation axis of the rotating disk. The scattered object dropped on the rotating disk is separated from the rotating disk by a blade member disposed on the rotating disk at a predetermined inclination angle with respect to a second axis straight line in the diameter direction passing through the rotation axis of the rotating disk. Caught to grip between.
The spread object caught by the blade member moves to the outside of the blade member (outer side of the disk of the rotary disk) by the rotation of the rotary disk, and further, the traveling direction of the vehicle and the spread object passing through the rotation axis of the rotary disk. Is carried in the rotating direction of the rotating disk along an arc-shaped spraying guard member provided so as to cover the outer periphery of the rotating disk in a predetermined angular range in the circumferential direction with respect to the first axis straight line in the spraying direction.

Hereinafter, the spraying device of the present invention will be described in detail with reference to the drawings as appropriate. The embodiment of the present invention includes the illustrated form, but is not particularly limited thereto.
In the present embodiment, there is provided a spraying apparatus A which is loaded and mounted on a rear part of a bed of a vehicle running on a road and configured to spray a granular anti-freezing agent (snow-melting agent), which is a spray, toward the rear of the vehicle. This will be described by way of an embodiment.

<< Configuration of spraying device A >>
The spraying device A is mounted in the rear part of the bed b of the vehicle B such as a truck in a state fixed by a rope or the like, and spreads the deicing agent M in a wide-angle (planar) at a spreading width L corresponding to the road width of the traveling lane. (Approximately fan-shaped when viewed).
The spraying device A is a sprayer that sprays a hopper 1 in which an antifreezing agent M is stored and a defrosting agent M that naturally falls from a discharge / drop opening 2 described later of the hopper 1 toward the rear of the traveling vehicle B. The unit 3 is provided as a main configuration.

<< Configuration of Hopper 1 >>
The hopper 1 has an upper surface opened in a square shape in a plan view, and forms a vertical wall on the rear side wall 1a on the rear side of the vehicle B in a state where the hopper 1 is mounted on the carrier b of the vehicle B. The front side wall surface 1b and the side wall surfaces 1c on the vehicle width direction side of the vehicle B are gradually inclined so as to narrow toward the lower center of the rear wall surface 1a except for the upper opening side.
That is, the hopper 1 has a funnel shape in which the front wall surface 1b and the both side wall surfaces 1c are narrowed toward the lower center of the rear wall surface 1a, and has the discharge drop port 2 in the lower center. The discharge drop port 2 is opened in a rectangular shape that is long in the vehicle width direction of the vehicle B diagonally downward toward an inclined extension line of the front wall surface 1b of the hopper 1.
Since the front side wall 1b and both side walls 1c are formed in a funnel shape narrowing toward the lower central discharge outlet 2 of the rear side wall 1a in this manner, the deicing agent M in the hopper 1 is formed. Is slid down (flows down) by its own weight toward the discharge / fall port 2, and is spontaneously dropped from the discharge / fall port 2 onto a rotating disk 4, which will be described later, of the spraying unit 3.

In such a configuration, the hopper 1 is supported and installed in a suspended manner in an apparatus machine frame (frame) 100 framed in a square shape, and is fixedly mounted on the rear portion of the bed b of the vehicle B. .
The four corner support frames 101 on the front and rear sides of the machine frame 100 are provided with a horizontal U-shaped hook member 102 for hanging a rope or the like for fixing the machine frame 100 to the carrier b. By spreading such as from the carrier b to the hanging member 102, the spraying device A can be mounted immovably fixed to the rear part of the carrier b.

  In addition, on both left and right sides of a rear lower side frame 103 which forms a bottom portion of the apparatus machine frame 100 in a substantially rectangular shape in plan view, abutment members 104 for positioning when the spraying apparatus A is mounted on the loading platform b are provided. The spraying device A is provided downward, and the abutting member 104 is addressed to the rear side of the loading platform b (such as a rear swing hanging down from the hinge portion). It can be mounted. That is, there is no danger that the rotating disk 4 and the like of the spraying unit 3 which are protruded rearward from the loading bed b and positioned below are damaged by accidentally hitting the rear part of the loading bed b. The spraying device A can be mounted on the bed b.

  A discharge mechanism 2 provided at the lower center of the hopper 1 of the spraying device A mounted on the rear portion of the loading platform b is provided with a shutter mechanism so that the antifreezing agent M can be sprayed during or after spraying. The discharge / fall port 2 can be opened and closed.

<< Configuration of shutter mechanism >>
The shutter mechanism is provided outside the rear wall surface 1a on the rear wall surface 1a of the hopper 1 where the discharge drop opening 2 opens, and includes a shutter plate 200 and a cylinder 201 serving as a driving unit. .
The shutter plate 200 has a laminated form, and is provided so as to be vertically slidable by a vertical guide member 202 attached to the rear side wall surface 1a so as to sandwich the discharge drop port 2 from the left and right. It opens and closes. The laminated form of the shutter plate 200 includes a plate material made of a material having both sealing properties and lubricity so as to sandwich the central metal plate material in a sandwich shape.

The cylinder 201 is of an electric type, and is started and stopped by a spray controller (not shown) in the driver's seat of the vehicle B, and is attached to the rear wall surface 1a with the rod 203 turned vertically downward. Then, the cylinder 201 allows the rod 203 to be inserted into the cylindrical connecting member 205 which is mounted upright on the shutter plate 200 via the bracket 204, and connects the rod 203 to the connecting member 205 so that the connecting position can be adjusted. I'm trying to get.
More specifically, the rod 203 and the rod extending member 206 are connected to each other by inserting and replacing the connecting pin 208 into a pin fixing hole 207 that is opened at equal intervals in the axial direction of the rod extending member 206 that is coaxially connected to the rod 203. Can be appropriately adjusted.

≫Configuration of spraying unit 3≫
Next, the spraying unit 3 that sprays the anti-freezing agent M that naturally falls from the discharge / fall port 2 of the hopper 1 by opening the shutter plate 200 of the shutter mechanism will be described.
The spraying unit 3 sprays the deicing agent M naturally falling from the discharge / fall port 2 of the hopper 1 in a wide angle direction toward the rear of the vehicle B traveling by rotating the rotary disk 4. Is mounted on the outside of the hopper 1 that is open and supported by a support frame 300 attached to the apparatus machine frame 100.
The spraying unit 3 includes a rotating disk 4 having a blade member 5, an electric motor 6 serving as a rotation drive source of the rotating disk 4, a scatter guard member 7 disposed along the outer periphery of the rotating disk 4, and an electric motor. The main components are a reversing box 8 in which the inside 6 is provided, and a receiving member 9 for guiding and guiding the antifreezing agent M in the hopper 1 falling from the discharge dropping port 2 onto the rotating disk 4.

≫Configuration of rotating disk 4≫
The rotating disk 4 has a flat plate shape having an outer diameter (diameter) of a predetermined size, and is coaxially connected to an output shaft 6a of the electric motor 6 via a connecting member 10 as shown in FIGS. The power transmission shaft 11 is formed so as to be fixedly mounted and supported by a ring member 12 and a bolt nut 13 on the lower end side of the output transmission shaft 11.
A plurality (three in the illustrated example) of blade members 5 are radially provided on the rotating disk 4.

<< Configuration of Blade Member 5 >>
The blade member 5 is formed to have a length corresponding to the radius of the rotating disk 4, is arranged on the rotating disk 4 in an upright shape at an inclination angle θ2 described later, and rotates on the upper side 5 a side. The disk 4 is formed in an approximately L-shape in a reverse direction when viewed in a vertical cross-section that is bent in the rotation direction of the disk 4. As a result, the antifreezing agent M naturally dropped from the discharge / fall port 2 of the hopper 1 onto the rotating disk 4 is caught and caught between the rotating disk 4 and the rotation of the rotating disk 4 ( The antifreezing agent M is configured to be pushed out from the rotating disk 4 by centrifugal force) and extruded.

  The electric motor 6 is a DC motor that can switch the number of revolutions steplessly by a volume knob or the like provided in the spray controller of the driver's seat of the vehicle B. As shown in FIGS. The output shaft 6a is installed inside the reversing box 8 supported in the frame body 300 by the rotation support shaft 14 so that the output shaft 6a can be turned upside down. The output shaft 6a that is vertically downward in the reversing box 8 is connected to the output transmission shaft 11 attached to the rotation axis P1 of the rotation disk 4 by the ring member 12 and the bolt and nut 13 by the connection tool 10. The rotating disk 4 is driven to rotate. The output transmission shaft 11 is rotatably mounted and supported on the bottom of the reversing box 8 by a cylindrical support member 15 having a bearing 16 on the inner axis.

<< Configuration of the spray guard member 7 >>
Next, the scatter guard member 7 that covers the rotating disk 4 within a predetermined circumferential angle θ1 range, which will be described later in detail, on the outer periphery of the rotating disk 4 in the rotating direction of the rotating disk 4 will be described.
As shown in FIGS. 4 and 5, the scatter guard member 7 is discharged from the discharge / fall port 2 of the hopper 1 and located on the rotating disk 4 located closer to the traveling direction of the vehicle B than the disk axis P1 of the rotating disk 4. When the anti-freezing agent M that falls naturally through the receiving member 9 is pushed out of the rotating disk 4 in cooperation with the rotation of the rotating disk 4 and the blade member 5, the spraying direction of the vehicle B traveling Behind, it plays a role of regulating the spray direction and the spray width (spray range) L of the antifreeze agent M so that the spray width L becomes the lane width of the traveling lane. In other words, the spray guard member 7 cooperates with the blade member 5 to regulate the spray direction and the spray width L of the deicing agent M for realizing efficient spray without waste.

  As shown in FIGS. 2 to 5, the scatter guard member 7 has a length (arc length) corresponding to a semicircle of the rotating disk 4 using a band-shaped plate having a predetermined width (height). It is formed in a curved arc shape. As shown in FIGS. 2 and 3, the scatter guard member 7 is attached to and supported by a lower end of a support member 15 attached to the bottom of the reversing box 8 via a top plate (fixed disk) 17. As shown in FIG. 5, the disk 4 is provided so as to cover the outer periphery of the disk in the rotation direction of the rotary disk 4 within a predetermined circumferential angle θ1 range.

  The top plate 17 for mounting and supporting the scatter guard member 7 is slightly larger than the diameter of the rotary disk 4 and is formed in a disk shape corresponding to the size (arc) of the scatter guard member 7. The lower end of the support member 15 is fixedly attached and supported by a ring member 18 and a bolt nut 19. The attachment of the scatter guard member 7 to the top plate 17 is performed by welding, spotting, or the like.

<< Configuration of Inversion Box 8 >>
The reversing box 8 in which the top plate 17 is mounted and supported on the bottom via the support member 15 and in which the electric motor 6 is provided is composed of two members: a box body 8a and a cover 8b. As shown in FIGS. 2 and 3, the box body 8 a is bent from the iron plate having a thickness that maintains appropriate rigidity (strength) to the rear side (spraying direction) and is inclined substantially in a vertical side view. It is L-shaped, vertically long, and is formed in a substantially U-shape opened rearward in a cross-sectional view. The box main body 8a mounts and mounts the electric motor 6 on the motor installation plate 20 provided on the bottom side in a vertical position, and the output shaft 6a and the output transmission shaft 11 below the motor installation plate 20. Are connected coaxially by the connector 10.

In such a configuration, the box body 8 a is supported via the rotation support shaft 14 on the left and right horizontal frame members 302 provided on the both side frame portions 301 on the upper half side of the support frame 300. The support frame 300 is mounted between both side frames 301 so as to be able to be turned upside down. Cylindrical shaft support members 303 facing inward are attached to the horizontal frame members 302 on both sides, and small-diameter portions at both ends of the rotation support shaft 14 are rotatably inserted and supported by the shaft support members 303. I have to.
On the other hand, as shown in FIGS. 2 and 3, the cover portion 8 b is formed in a downward, substantially inverted L-shape so as to cover the opening between the upper surface and the rear surface of the box body portion 8 a. It is configured to be detachably attached to the main body 8a.

  In this embodiment, as shown in FIG. 6, a safety switch that cuts off the current to the electric motor 6 between the reversing box 8 and the support frame 300 when the reversing box 8 is turned upside down. 22.

The safety switch 22 includes a switch box 22a disposed on the support frame 300, and the switch box 22a includes a push button 23 that is urged outward by an internal spring material or the like. The safety switch 22 includes a button pressing ON / OFF switching member 22b disposed on the reversing box 8 side, and when the push button 23 is pressed, a current is supplied to the electric motor 6 and The power supply to the electric motor 6 is cut off in a state where the button pressing ON / OFF switching member 22b is separated and the push button 23 returns to the external convex shape.
That is, as shown in FIG. 6 (a), when the reversing box 8 in which the rotating disk 4 and the like are positioned below is in a reverse reversing and returning state (when the antifreezing agent M is sprayed), a current is supplied to the electric motor 6, As shown in FIG. 6B, when the reversing box 8 in which the rotating disk 4 and the like are positioned upward is turned upside down, the power supply to the electric motor 6 is cut off.

  In this embodiment, as shown in FIGS. 2, 3, and 6, two types of attachments are provided in which the reversing box 8 is fixedly mounted on the support frame body 300 when the reversing box 8 is in the downwardly reversed state and in the upwardly reversed state. Parts 24 and 25 are provided.

The mounting portion 24 is for temporarily fixing the reversing box 8 to the support frame 300 when the reversing box 8 is turned upside down and when it is turned back down again. A pin member 24a is provided at a predetermined vertical position, and a hook member 24b is provided at a predetermined position on the reversing box 8 and hooks on the pin member 24a.
On the other hand, the mounting portion 25 is for permanently fixing the reversing box 8 to the support frame 300 in a state where the reversing box 8 is temporarily fixed to the support frame 300 by the mounting portion 24. And a knob member 25b screwed to the nut member 25a via a bracket 27 disposed at a predetermined position on the reversing box 8 side. .
In this way, while the reversing box 8 is fixedly attached to the lower reversing return position shown in FIG. 6A and the upper reversing position shown in FIG. Then, the maintenance of the discharge / fall port 2 of the hopper 1 can be safely performed after moving to the spraying site or after the spraying is completed.

<< Configuration of Receptacle Member 9 >>
Next, a receiving member which receives the anti-freezing agent M discharged and dropped from the discharging and dropping port 2 of the hopper 1 from the discharging and dropping port 2 and guides and guides the anti-freezing agent M onto the rotating disk 4 disposed diagonally below. 9 will be described.

  The receptacle member 9 is formed in a trumpet shape having a predetermined rectangular upward opening extending in the vehicle width direction of the vehicle B and opening upward at one long side and both short sides. The receptacle member 9 is attached to the opening of the top plate 17 that is located obliquely below the discharge drop port 2, so that the deicing agent M in the hopper 1 that is discharged from the discharge drop port 2 and falls is removed. As shown in FIGS. 4 and 5, the guide is guided on a rotating disk 4 located in the traveling direction of the vehicle B with respect to the rotating main shaft P.

In the spraying device A according to the present embodiment configured as described above, the spraying guard for the first axis straight line X1 in the traveling direction of the vehicle B passing through the rotation axis P1 of the rotating disk 4 and the spraying direction of the deicing agent M. It is preferable to set the angle θ1 of the member 7 in the rotation direction of the rotating disk 4 in a range of 5 ° to 40 °. That is, the scattered object on the rotating disk 4 that is dropped (supplied) to the falling position D closer to the traveling direction of the vehicle B than the rotating shaft center P1 is caught by the blade member 5 with the rotation of the rotating disk 4 and is rotated in the rotating direction. When being carried, it moves toward the outside of the blade member 5 (toward the outer periphery of the disk).
For this purpose, as shown in FIG. 5, the first axis of one side edge 7a of one side of the scatter guard member 7 which is located across the first axis straight line X1 in the traveling direction of the vehicle passing through the rotation axis P of the rotating disk 4. The angle θ1 with respect to the first axis line X1 and the angle θ1 with respect to the first axis line X1 of the other side edge 7b of the scatter guard member 7 positioned in a direction away from the first axis line X1 in the spraying direction of the object to be sprayed are 5 ° to 40 °. It is preferable to set the angle in the range of °.
The reason is that when the angle θ1 is set to 5 ° or less, the sprayed material is not pushed out from one side edge 7a of the spray guard member 7 close to the drop position in the spraying direction in the rear of the vehicle in which the sprayed object runs. There is a possibility that the sprayed material may be extruded toward the lower side of the sheet of FIG. 5 and the sprayed material carried by the blade member 5 to the other side edge 7b of the spray guard member 7 is directed toward the spraying direction behind the vehicle. Although it is pushed and pushed, there is a possibility that the pushing and pushing direction may be shifted to the lower side of the paper surface of FIG. In other words, when the angle θ1 is 5 ° or less, the antifreeze agent M may not be able to be evenly and uniformly distributed right and left on the first axis straight line X1 over the entire road width (travel lane) on which the vehicle travels. This is because the anti-freezing agent M may jump out to the side of the road or the like and be consumed uselessly.
On the other hand, if the angle θ1 exceeds 40 °, it is possible to push out the sprayed material toward the spraying direction behind the vehicle on the side edge 7a side of the spraying guard member 7, but the spraying guard member 7 has On the other side edge 7b side, there is a possibility that, instead of being extruded in the spraying direction behind the vehicle, it is extruded toward the upper side of the paper of FIG. 5 and extruded toward the vehicle. This is because it is difficult to achieve the intended purpose.
Therefore, in the scatter guard member 7 provided on the outer periphery of the rotating disk 4 in the rotation direction of the rotating disk 4 according to the present embodiment, the angle θ1 with respect to the first axis straight line X1 is set in a range of 5 ° to 40 °, preferably 10 ° to 40 °. It is important to set the angle in the range of 30 °, particularly preferably 25 °, in order to achieve the intended purpose.

Further, as shown in FIG. 5, the intersection with the second axial straight line X2 in the diametric direction passing through the rotation axis P1 of the rotation disk 4 at one end located on the outer peripheral side of the disk is defined as the base point P2, and the rotation axis P1 side The inclination angle θ2 of the blade member 5 disposed on the rotating disk 4 with respect to the second axis straight line X2 so that the other end of the blade member is separated from the second axis straight line X2 in the rotation direction of the rotating disk 4 is 20 °. It is preferable to set the angle in the range of 〜50 °.
The reason is that, when the inclination angle θ2 is set to 20 ° or less, the scattered material caught by the blade member 5 moves toward the outside of the blade member 5 (in the outer peripheral direction of the disk) immediately after being caught, and Escape. That is, there is a possibility that the blade member 5 may not be carried in the rotation direction. When the inclination angle θ2 exceeds 50 °, the spatter caught by the blade member 5 is not carried in the rotation direction by the blade member 5. This is because the spraying agents are gathered in the direction of the rotation axis P1 of the rotating disk 4, and the spraying agents interfere with each other, so that the spraying direction due to cooperation with the spraying guard member 7 is not determined, and there is a possibility of irregularity.
Therefore, in the blade member 5 disposed on the rotating disk 4 according to the present embodiment, the inclination angle θ2 of the rotating disk 4 in the rotation direction with respect to the second axis straight line X2 is set in the range of 20 ° to 50 °, It is important to set the angle preferably in the range of 35 ° to 45 °, particularly preferably 40 °. That is, by setting the inclination angle θ2 of the blade member 5 on the rotating disk 4 with respect to the second axis straight line X2 in the range of 20 ° to 50 °, the rotating disk of the scatter guard member 7 with respect to the first axis straight line X1 described above. The synergistic action with the angle θ1 in the rotation direction 4 is effective in achieving the intended purpose.

  In such a configuration, the spraying device A is provided with a stirrer 400 for manual operation between both side wall surfaces 1c near the discharge drop port 2, as shown in FIGS.

The stirrer 400 stirs the anti-freezing agent M in the hopper 1 by manually rotating the spraying worker, and as shown by a two-dot chain line in FIGS. A rotating shaft 401 made of a pipe material which is attached in an externally penetrating manner through the shaft 27; a stirring shaft 402 which is attached at several positions in the axial direction of the rotating shaft 401 so as to be turned in three directions around the circumference; And a manual handle 403 that is detachably attached to one end side of the camera.
As shown in FIG. 7, by attaching the handle 403 to one end of the rotating shaft 401 projecting to the outside and rotating the rotating shaft 401, the rotating shaft 401 is discharged and dropped by the stirring rods 402 at several places in the axial direction. The antifreezing agent M near the mouth 2 is stirred. This prevents the antifreeze material M in the hopper 1, particularly the antifreeze agent M near the discharge drop port 2, from being bleached, and the antifreeze agent M is quickly spread on the rotating disk 4 from the discharge drop port 2 during spraying. To fall naturally.

Further, in this embodiment, as shown in FIG. 7, a pair of right and left stands C can support the spraying device A.
That is, as shown in FIGS. 1 and 6, a predetermined height position of the vertical frame member 107 attached between the lower left and right lower frame members 105 and the intermediate frame member 106 constituting the apparatus machine frame 100 of the spraying apparatus A. Then, a connecting member 500 made of a round pipe material or the like is attached in a laterally open shape. Then, as shown in FIG. 7, a substantially T-shaped T-shape is seen from a side view from a horizontal rod member 501 provided with a caster 502 and a vertical rod member 503 erected from the longitudinal center of the horizontal rod member 501. A stand C is provided.

  In such a configuration, as shown in FIG. 7, the insertion connection member 504 provided on the upper side of the vertical rod member 503 of the stand C is detachably inserted and connected to the connection member 500 of the apparatus frame 100 so as to be detachable. The spraying device A can be supported on both left and right sides. The insertion state of the insertion connecting member 504 with respect to the connecting member 500 can be immovably connected by pinning or the like.

The vertical rod member 503 of the stand C includes an upper rod part 503a and a lower rod part 503b made of a square pipe material, and a screw rod member (not shown) provided in the upper rod part 503a is replaced with a lower rod part 503b. The upper rod portion 503a is connected to the lower rod portion 503b by screwing and inserting into a nut member (not shown) provided in the above. Then, by turning the handle 505 attached to the upper end of the screw rod member protruding from the upper end of the upper side rod portion 503a, the height of the upper side rod portion 503a can be adjusted (up and down movement with respect to the lower side rod portion 503b). Possible). After the height of the upper rod 503a is adjusted, the upper rod 503a can be immovably connected to the lower rod 503b by pinning or the like.
By using the stand C configured as described above, the loading / unloading operation of loading and unloading the spraying device A from the loading platform b on the loading platform b of the vehicle B can be easily performed alone, and at the time of off-season after the end of the spraying. Is effective for storing the spraying device A.

[Description of operation]
Next, the use of the spraying apparatus A according to the present embodiment configured as described above will be briefly described.
First, when the spraying device A is mounted on the rear portion of the bed b of the vehicle B, the spraying device A is performed using a pair of left and right stands C shown in FIG. At this time, the abutting member 104 provided on the apparatus frame 100 is addressed to the rear side of the loading bed b or the like, so that the rotating disk 4 or the like of the spraying unit 3 does not hit the loading bed b and is located behind the loading bed b. In the state where the rotating disk 4 and the like are positioned at a predetermined height from the road surface in the above, the spraying device A can be placed on the rear portion of the loading platform b. After placing the spraying device A on the carrier b, a rope or the like is laid over the hook members 102 at the four corners provided in the apparatus frame 100 to fix the spraying device A immovably on the carrier b, The power cable of the third electric motor 6 is connected to a power source such as a battery of the vehicle B, so that power is supplied to the electric motor 6.

  In this way, after the spraying device A is mounted on the rear portion of the loading bed b, the antifreezing agent M is put into the hopper 1, and when the spraying operation is performed by moving to the spraying site, the electric motor 6 is controlled by the spraying controller in the driver's seat. Is started, the electric cylinder 201 is started in the shutter opening direction, and the shutter plate 200 is opened, so that the spraying operation of spraying the deicing agent M toward the rear of the running vehicle B can be performed. At this time, by switching the number of rotations of the electric motor 6 by a volume knob provided in the spray controller or the like, the spraying operation can be performed with the spray width L corresponding to the lane width of the traveling lane.

During the spraying operation, the anti-freezing agent M contained in the hopper 1 is separated by the front side wall surface 1b and both side wall surfaces 1c inclined toward the discharge center 2 at the lower center of the vertical rear wall surface 1a of the hopper 1. It slides down (flows down) by its own weight toward the discharge / fall port 2. The anti-freezing agent M that has slipped down to the discharge drop port 2 is discharged onto the rotating disk 4 by the receiving member 9 disposed diagonally below the discharge drop port 2 (a position lower than the height of the bed of the vehicle B). After being dropped and rotated by the rotating disk 4, it is pushed out and spread toward the rear (traveling lane) of the vehicle B traveling from above the rotating disk 4.
At this time, the deicing agent M guided from the discharge drop port 2 to the receiving port member 9 and dropped to the drop position D on the rotary disk 4 closer to the traveling direction of the vehicle B than the rotation axis P is rotated by the rotation of the rotary disk 4. The blade member 5 disposed on the rotating disk 4 at an inclination angle θ2 with respect to the second axis straight line X2 passing through the axis P is caught so as to be gripped between the rotating disk 4 and the blade member 5.

The antifreezing agent M caught by the blade member 5 moves to the outside (the outer peripheral side of the disk) of the blade member 5 due to the rotation of the rotating disk 4 and also passes through the rotation axis P of the rotating disk 4. At a circumferential angle θ1 with respect to the straight line X1, it is carried in the rotating direction of the rotating disk 4 along an arc-shaped scatter guard member 7 attached so as to cover the outer periphery of the rotating disk 4.
Then, the rotation direction of the rotating disk 4 is sequentially changed from the one side edge 7a near the drop position D of the deicing agent M on the rotating disk 4 among the two side edges 7a and 7b of the spray guard member 7. The deicing agent M is spread and extruded from the outer periphery of the disk not covered by the spray guard member 7 reaching the other side edge 7b side at a spray width L corresponding to the lane width of the traveling lane.

  As described above, according to the spraying apparatus A according to the embodiment of the present invention, unlike the related art, a screw or the like for dropping (supplying) the antifreezing agent in the hopper onto the rotating disk is not provided at the bottom of the hopper. The antifreezing agent M in the hopper 1 can be sprayed in the spraying direction toward the rear of the vehicle B and the spraying width L (running lane width) without waste while allowing the antifreezing agent M in the hopper 1 to fall naturally on the rotating disk 4.

In other words, the anti-freezing agent in the hopper 1 is formed by gradually inclining the front wall surface 1b and both side wall surfaces 1c toward the discharge drop port 2 provided in the lower center of the vertical rear wall surface 1a of the hopper 1. M slides down (flows down) toward the discharge fall port 2 by its own weight. The falling position D of the deicing agent M from the discharge drop port 2 onto the rotating disk 4 is closer to the traveling direction of the vehicle B than the rotating spindle P of the rotating disk 4 guided (guided) by the receiving member 9. Accordingly, the present invention was completed by paying attention to the fact that the antifreezing agent M in the hopper 1 having a funnel shape narrowed toward the discharge drop port 2 is surely dropped onto the rotating disk 4. Things.
Further, the spraying width of the anti-freezing agent M dropped to the drop position D on the rotating disk closer to the traveling direction of the vehicle B than the rotating shaft center P in the spraying direction toward the rear of the running vehicle B is reduced. In order to scatter at L, the side edges 7a and 7b of the scatter guard member 7 curved in an arc shape with a length (arc length) corresponding to a semicircle of the rotating disk 4 are attached to the disk of the rotating disk 4. The scatter guard member 7 is provided on the outer periphery of the rotating disk 4 in the rotation direction of the rotating disk 4 in a state where the scatter guard member 7 is positioned at a predetermined angle θ1 in the circumferential direction with respect to the first axis straight line X1 in the traveling direction passing through the axis P and the spreading direction. By paying attention, the present invention has been completed.

Next, a mechanism for eliminating clogging of the antifreezing agent (snow melting agent) in the hopper 1 will be described. The anti-freezing agent to be put into the hopper 1 has various shapes, but can be roughly divided into a granular material, a powder material, and a flake material. Such an antifreezing agent has a property that it absorbs moisture easily and the fluidity deteriorates when moisture is absorbed. The anti-freezing agent that has deteriorated in fluidity due to the absorption of moisture does not fall from the rat hole or the drop hole 2 where only the upper part of the drop hole 2 falls in the hopper 1 and the periphery thereof is solidified without being collapsed. Bridges are likely to occur, and it becomes difficult to continuously discharge the antifreeze material housed in the hopper 1 from the discharge / fall port 2.

On the other hand, in another embodiment of the present invention, a hammer mechanism as shown in FIGS. 8 to 10 is provided. The hammer mechanism 600 is installed on the lower frame member 105 in front of the hopper 1 and intermittently taps a position below the front wall surface 1b of the hopper 1 from outside to discharge the antifreezing material in the hopper 1 It has a function to continuously discharge from. Since a space below the front side wall surface 1b of the hopper 1 becomes an empty space, by installing the hammer mechanism 600 there, the hammer mechanism 600 can be installed without increasing the size of the apparatus.

  The hammer mechanism 600 includes a hammer body 601 for striking the front wall surface 1b, an arm 602 that is pivotally supported so that one end supporting the hammer body 601 and the other end serving as the power point 602a swing up and down, respectively. It includes a spring 603 for urging the other end side downward, and a driving unit 604 for rotationally driving a cam body 604A that lifts up and separates a point of force 602a of the arm 602 upward.

  The arm 602 has its both ends supported by a horizontal shaft 606 on which a support 605 is installed, so that both ends thereof can swing up and down. A hammer body 601 is attached to the front end side of the arm 602. In the illustrated example, a horizontal shaft 607 is provided between a pair of arms 602, and a drum-shaped hammer body 601 is mounted so as to be supported by the horizontal shaft 607.

  The spring 603 has one end locked to the front end of the arm 602 and the other end locked to the support 605 to urge the front end of the arm 602 downward. Thereby, the rear end side of the arm 602 to which the hammer body 601 is attached is urged upward by the spring 603.

  The drive section 604 includes a cam body 604A and an electric motor 604B that rotationally drives the cam body 604A. The cam body 604A is driven to rotate by the constant rotation at a reduced speed of the electric motor 604B, and an intermittent cycle in which the hammer body 601 hits the front wall surface 1b at the rotation speed is set. The cam body 604A, which is rotationally driven, repeats the function of lifting the power point 602a of the arm 602 upward and separating it by contacting the power point 602a of the arm 602 at the tip. The electric motor 604B of the drive unit 604 is supplied with power from a power supply (battery: not shown) mounted on the vehicle B, and is turned on and off by a switch operation of a control box (not shown) installed in the driver's seat of the vehicle.

  10A to 10C show the operation of the hammer mechanism 600. The operation of the hammer mechanism 600 is started by turning on the electric motor 604B of the drive unit 604 during the spraying operation. When the cam body 604A is rotated by the rotation of the electric motor 604B, the front end side of the arm 602 is lifted by the repulsion of the elastic force of the spring 603 only while the tip end of the cam body 604A is in contact with the power point 602a of the arm 602. When the distal end of the cam body 604A moves away from the point of force 602a of the arm 602, the front end of the arm 602 is pushed down by the elastic force of the spring 603, and the rear end of the arm 602 is pushed up. The attached hammer body 601 hits the front wall surface 1b of the hopper 1.

  The cam body 604A has a pair of tips at 180 ° around the rotation axis. The hammer body 601 hits the front wall surface 1b of the hopper 1 twice with one rotation of the cam body 604A. The intermittent period at which the hammer body 601 hits the front wall surface 1b is preferably about once per second, and therefore, the rotation speed of the output shaft of the electric motor 604B (the rotation speed of the cam body 604A) should be set to about 30 rpm. Is preferred. The force with which the hammer body 601 hits the front wall surface 1b can be appropriately adjusted by the elastic force of the spring 603 or the like.

  By providing such a hammer mechanism 600, the spraying apparatus A according to the embodiment of the present invention can discharge the antifreeze material stored in the hopper 1 from the discharge drop port 2 onto the rotary disk 4 without clogging. it can. Thereby, even when the antifreezing material absorbs moisture and the fluidity deteriorates, the spraying operation can be smoothly performed.

  When the hammer mechanism 600 is operated, a hammer sound is generated in which the hammer body 601 hits the front wall surface 1b, but the noise is suppressed by providing the hammer sound suppression member 610 at the contact position of the hammer body 601 on the front wall surface 1b. It becomes possible. By forming the hammer noise suppressing member 610 as a laminate of a sponge material and a plastic material, it is possible to suppress the generation of hammer noise while applying an appropriate impact.

  The position where the hammer body 601 hits the front wall surface 1b is a position below the front wall surface 1b, and is preferably near the back surface of the discharge drop port 2. When the hammer body 601 hits such a position, the bridge and ratholes of the anti-freezing material in the hopper 1 are effectively broken, and the anti-freezing material is smoothly discharged from the discharge / fall port 2. The hammer mechanism 600 is provided with a cover 611 that covers the driving unit 604 and the like as necessary.
