Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a traveling power spreader configured to perform a spraying operation of powdery or liquid sprayed materials such as agricultural chemicals, fertilizers, and seeds while traveling on a shore.
[0002]
[Prior art]
As a power spreader used for paddy field control, fertilization, etc., conventionally, a backpack type is generally used, but this backpack type power spreader can be used only for a body part such as a storage tank, a blower and a prime mover. Although it is quite heavy, in addition to that, the weight of sprayed materials such as pesticides, fertilizers and seeds stored in the storage tank is also added, so you can carry it while walking on the shores and fields with poor scaffolding It is extremely hard work to carry out spraying work, and considering the recent aging of farmers, it is desirable to be able to carry out spraying work while mounting a storage tank, blower and prime mover on a carriage .
[0003]
In order to meet such a demand, for example, as seen in Japanese Utility Model Publication No. 4-50929, a base frame (cart) equipped with wheels has a storage tank for storing scattered matter, and a storage tank in the storage tank. A centrifugal blower that generates conveying air for spraying the spatter and an engine as a prime mover that is a drive source of the centrifugal blower are mounted and held, and a push handle is provided, and the push handle is pushed. Traveling power spraying that drives the blower by the engine while traveling on uneven rough terrain such as a shore, and performs spraying work through a tubular spraying tool such as a direct injection pipe connected to the blower A machine has been proposed.
[0004]
[Problems to be solved by the invention]
However, in the conventional traveling power spreader as described above, heavy objects such as a centrifugal blower, an engine as a prime mover, a storage tank, and the like are mounted and held on a base frame provided with wheels as it is. Therefore, the overall height of the loaded heavy parts (parts consisting of storage tanks, engines, blowers, etc.) is increased and the center of gravity is also increased, resulting in poor posture stability, especially on the uneven shores. When traveling on rough terrain, it is difficult to control the aircraft, and it is easy to cause tilting, falling, falling.
[0005]
More specifically, when the conventional traveling power spreader is driven on uneven terrain such as a rough ridge, the wheel picks up irregularities on the uneven terrain, so that the base frame and the mounted heavy load part are only up and down. The center of gravity position fluctuates greatly to the left and right, making it difficult to balance the left and right, and the handle that is integrated with the mounted weight part and the base frame also swings to the left and right. The wheel will fall in an undesired direction, and the wheel will fall from the shore to the irrigation channel of the rice field, etc., the stability of the aircraft will be impaired and the inclination can not be suppressed, and if it is severe, it will fall down Problems arise.
[0006]
Further, when the body swings left and right, a tubular spraying tool such as a direct injection pipe connected to the discharge port of the blower also swings left and right together. In this case, since the nozzle part (tip part) of the tubular spreader is usually positioned so as to protrude laterally from the machine body, if it swings to the left and right, the spray emission angle of the sprayed material with respect to the horizontal plane is Therefore, there is a problem in that the spraying density of the sprayed material on the field crops and the like varies, resulting in so-called spraying unevenness and a decrease in spraying performance.
[0007]
The present invention has been made in view of such problems, and the object of the present invention is to allow the steering wheel to swing in the left-right direction even when traveling on rough terrain such as a ridge. It is possible to improve posture stability and running stability by suppressing as much as possible, and to reduce spraying unevenness and improve spraying performance, so that spraying work can be performed easily, properly and efficiently. It is to provide a traveling power spreader.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the traveling power spreader according to the present invention basically has main wheels arranged in a straight line in the front-rear direction on a base frame having a swinging support shaft extending in the front-rear direction. A steering handle is provided, a swing frame is supported on the swing support shaft so as to be swingable up and down, and a side wheel is disposed on one side of the swing frame in a lateral direction with respect to a moving direction of the machine body. In addition, a storage tank in which the spatter is stored, a blower that generates a conveying wind for spraying the spatter in the storage tank, and a prime mover that is a drive source of the blower are mounted on the swing frame. In a preferred embodiment, the swing frame is weighted in a direction in which the side vehicle is constantly pressed against the road surface by heavy objects such as the storage tank, blower, and prime mover that are mounted and held on the swing frame.
[0009]
In the traveling power spreader according to the present invention configured as described above, a storage tank, a blower, a prime mover, etc. are mounted on a swinging support shaft provided in a base frame on which a steering handle and main wheels are disposed. Since the swing frame that is held and the side wheel is arranged is supported so as to be able to swing up and down, when traveling on rough terrain such as an uneven shore, when the main wheel picks up uneven terrain, Although the steering handle disposed on the base frame swings slightly from side to side, the loaded heavy parts such as the storage tank, the blower, and the prime mover can swing up and down independently of the base frame, in other words, are supported floating. Therefore, the left and right runout of the main wheel does not affect and does not follow the runout of the steering handle.
[0010]
In other words, when the side vehicle disposed on the swing frame side picks up unevenness on the rough terrain, the mounted heavy load portion swings left and right. In this case, the mounted heavy load portion is separated from the side vehicle and the base body. Since it is supported by both the frame (main wheels), the fluctuation of the center of gravity is softened and the stability is increased compared with the case where only the main wheels are supported, and the weight of the mounted heavy load part is shaken. Is difficult to be transmitted to the steering wheel side.
Therefore, even when traveling on rough terrain such as a shore, it is easy to control the aircraft by maneuvering with the steering handle, and the attitude stability and running stability are increased, making it difficult to cause a fall, fall, etc. Thus, the spraying work can be performed easily, properly and efficiently.
[0011]
Further, in a preferred aspect of the present invention, the tubular spraying tool of the direct injection pipe is connected to the discharge port of the blower through the curved jet pipe in a state of projecting laterally, and the tubular spraying tool is connected to the base frame. A support is provided for slidably supporting the straight pipe portion so as to allow longitudinal movement associated with vertical swinging with the swing support shaft of the straight pipe portion as the swing center axis. .
[0012]
As a preferable specific configuration of the support tool, a support rod standing on the base frame and a support rod disposed on the support rod and loosely fitted on the straight pipe portion so that an inclination angle of the straight pipe portion with respect to a horizontal plane is set. One or a plurality of ring-shaped or sleeve-shaped support guide members that are supported and guided so as to be movable in the longitudinal direction while being held substantially constant.
[0013]
In this way, by supporting the tubular spraying tool connected to the discharge port of the blower with the support tool disposed on the base frame, the mounted heavy article portion including the base frame or the blower when traveling on rough terrain. The support tool swings left and right together with the base frame, and the tubular spreader swings left and right together with the mounted heavy load portion with the swing support shaft as the swing center axis. When the straight pipe portion of the tubular spraying tool is guided by the support guide member of the support tool, the base frame or the mounted heavy object portion swings with the swing support shaft as the swing center axis. Thus, it can be moved relative to the support guide member in the longitudinal direction.
For this reason, even when traveling on rough terrain, the spray emission angle with respect to the horizontal plane of the spray sprayed and discharged from the tubular spraying tool hardly changes. Unevenness is reduced and spraying performance is improved.
[0014]

Here, as shown in FIG. 3, the side wheel 70 is inclined at a predetermined angle α so as to be inclined outwardly with respect to the front wheel 6 and the rear wheel 7 which are set up along the vertical line gg. Has been. By inclining the side vehicle 70 in this manner, as shown in FIG. 8, when the traveling power spreader 1 travels on the uneven ridge J, the side vehicle 70 has a slope Q of the rice field. Since the vehicle is in contact with the road shoulder portion of the shore J, the running stability is improved, the side wheel 70 is less likely to fall below the slope surface Q, and the front wheel 6 and the rear wheel 7 are on the side. It becomes difficult to be drawn to.
[0020]
The engine 60 is mounted and held on the upper surface side of the box-shaped support member 52 of the swing frame 50, and is integrated with a required number of fan holding brackets 66, 66,... Held and fixed to the L-shaped holding member 54. The above-mentioned centrifugal blower 65 is mounted on the above-mentioned weight by sandwiching a required number of vibration-proof mount members 68, 68,. In order to improve the stability by lowering the position of the center of gravity of the object part 5, the rotation shaft 65c of the fan 65b is set up along the vertical line gg so as to be orthogonal to the swing support shaft 10 when viewed from the side. In this state, in other words, it is mounted and held under the swing support shaft 10 in a vertical format.
[0021]
The engine 60 is a combined drive source for the centrifugal blower 65 and the rear wheel 7. That is, the engine 60 is provided with a spraying output shaft 61 (see FIG. 4) projecting downward and a traveling output shaft 62 (see FIGS. 1 and 2) projecting rearward. ing.

[0024]
On the other hand, on the front upper surface portion of the fan volute case 65a of the centrifugal blower 65, a connection portion 75a of a storage tank 75 for storing sprayed materials such as agricultural chemicals, fertilizers and seeds to be sprayed is connected and supported. The scattered matter in the storage tank 75 is dropped downward when a shutter (not shown) in the connection portion 75a is opened, and rides on the conveying air generated by the centrifugal blower 65, so that the fan volute case 65a It is sprayed and discharged to the outside through a tubular sprinkler 80, which will be described later, connected to the terminal (right side as viewed from the rear) outlet 65d. In order to adjust the amount of sprayed material (spraying amount) conveyed from the storage tank 75 by the blower 65, as can be understood with reference to FIG. A metering switching scale 78 and a metering lever 76 are provided. By operating the metering lever 76, the opening degree of the shutter in the storage tank connecting portion 75a is switched via the operation rod 77. It is like that.
[0025]
Here, the storage tank 75 and the centrifugal blower 65 mounted and held on the swing frame 50 are arranged slightly offset to the left side of the swing support shaft 10 (the central axis MM thereof), Further, the engine 60 is disposed slightly deviated to the right of the central axis MM, and the swing frame 50 is mounted on and held by the storage tank 75, the centrifugal blower 65, and the The mounted heavy article portion 5 including the engine 60 and the like is moderately weighted in a direction in which the left and right balances 70 are adjusted to press the side wheel 70 against the road surface.
[0026]
In addition, as shown in FIG. 8, here, the loaded heavy object portion 5 and the swing frame 50 can swing and tilt up to a maximum swing angle β, for example, about 20 degrees with respect to the vertical line gg. It is said that.

[0029]
In the traveling power spreader 1 of the present embodiment configured as described above, the swinging support shaft 10 provided on the base frame 2 on which the handles 31 and 32 and the front wheels 6 and the rear wheels 7 are disposed, The swing frame 50 on which the storage tank 75, the blower 65, the engine 60, and the like are mounted and held and the side wheel 70 is disposed is supported so as to be swingable up and down. During leveling, if the front wheels 6 and the rear wheels 7 pick up irregularities on rough terrain, the handles 31 and 32 disposed on the base frame 2 slightly swing left and right, but the storage tank 75, the blower 65, the engine Since the loaded heavy object portion 5 such as 60 is swingable up and down independently of the base frame 2, in other words, since it is supported in a floating manner, there is almost no left-right deflection of the front wheel 6 and the rear wheel 7. in front Run-out does not occur in the handle 31 and 32.
[0030]
In other words, when the side wheel 70 arranged on the swing frame 50 side picks up unevenness on the rough terrain, the mounted heavy load portion 5 swings up and down. In this case, the mounted heavy load portion 5 Since it is supported by both the side wheel 70 and the base frame 2 (the front wheel 6 and the rear wheel 7), the position of the center of gravity is higher than that in the case of supporting only by the main wheel as in the prior art. The fluctuations are eased and the running stability is increased, and the swing of the loaded heavy object portion 5 is hardly transmitted to the handles 31 and 32 side.
Therefore, even when traveling on rough terrain such as shore J, it is easy to operate the handle and control the aircraft, increasing posture stability and traveling stability, making it difficult to fall, fall, etc. Work can be done easily, properly and efficiently.
[0031]
Further, by supporting the tubular spreader 80 in a specific manner by the support tool 90, when the mounted heavy article portion 5 including the base frame 2 or the blower 65 swings up and down during rough terrain travel, The tubular spreader 80 also tends to swing from side to side with the swinging support shaft (center axis MM) 10 together with the mounted heavy load portion 5 as the swing center axis. The 80 direct injection pipes 84 are guided by the ring-shaped support guide members 93 and 94 of the support 90, and the mounted heavy object portion 5 swings with the swing support shaft 10 as the swing center axis. Thus, it is moved relative to the ring-shaped support guide members 93 and 94 in the longitudinal direction (direction as indicated by the white arrow in FIG. 3).
[0032]
For this reason, even when traveling on rough terrain, the spray discharge angle (θ) with respect to the horizontal plane of the spray sprayed and discharged from the tubular spray tool 80 hardly changes, and as a result, the spray spray density on the field crops and the like is uniform. To reduce spraying unevenness and improve spraying performance.
[0033]
Although one embodiment of the present invention has been described in detail above, the present invention is not limited to the above-described embodiment, and various designs can be made without departing from the spirit of the present invention described in the claims. Can be changed.
For example, in the embodiment described above, if a shock absorber made up of a coil spring, a leaf spring, a gas damper or the like is interposed between the side wheel 70 and the swing frame 50, the displacement of the mounted heavy load portion 5 can be mitigated. , Running stability is further increased.
[0034]
【The invention's effect】
As understood from the above description, the traveling power spreader according to the present invention suppresses the left and right swinging of the steering handle as much as possible even when traveling on uneven terrain such as uneven shores. Thus, it is possible to improve the posture stability and the running stability, to reduce the unevenness of spraying and to improve the spraying performance, and to achieve an excellent effect that the spraying work can be performed easily, appropriately and efficiently.
