EXAMPLES Examples will be described with reference to the drawings. Referring to FIG. 1, reference numeral 1 is an automatic cutting and winding device for vegetation according to the present invention, which is a device for cutting a main body frame 2 and a predetermined length and width arranged in this main body frame 2 in order from front to back. It is composed of a part 3, a conveyor part 4, and a device part 5 for winding cutting grass. In this case, the automatic cutting and wrapping device 1 for turf is suspended by a suspension device 6A beside the towing vehicle 6 and a tow bar 6B is attached between the towing vehicle 6 and the device 1. As a result, the roller portion of the device 1 is placed on the upper surface of the lawn by the suspending device 6A, and the tow vehicle 6 moves forward, so that the device 1 also moves at the same time, and the lawn cutting operation is performed.

The body frame 2 is composed of left and right side walls 2A and a front wall 2B stretched above the front surface of the side walls 2A. 2C is a rear wall. With reference to FIGS. 2 and 3, a device portion 3 for cutting to a specified length and width is provided with a cutter portion 3A which is arranged on the front surface of the main body frame 2 so as to be able to move up and down, and rotatably arranged behind the cutter portion 3A. The roller portion 3B provided, the rear cutter portion 3C swingably arranged behind the roller portion 3B, the sludge removing lever 3D obliquely provided behind the rear cutter portion 3C, and the sludge removing lever 3D. It is composed of an attached turf guide plate 3E.

Therefore, the cutter portion 3A is provided with an elevating plate 3A1 which is attached to an upper portion of the front surface of the body frame 2 so as to be vertically movable in a direction orthogonal to the traveling direction of the body frame 2.
A cutter body 3A2, which is connected to the lower end of the elevating plate 3A1 by a lateral pin P so as to be bent backward, and the elevating plate 3A2.
Cutter lever 3A1 connected to the upper end of A1 facing rearward
1, the upper end of the lifting plate 3A1 and the front wall 2B of the main body frame 2
Cutter fall acceleration spring 3A3 stretched between and
It consists of and. 3A12 is a cutter vertical holding spring.

Referring to FIG. 3, the roller portion 3B is attached to the outer periphery of the roller body 3B1 which is rotatably attached below the body frame 2 in a direction orthogonal to the traveling direction of the body frame 2. It is composed of a rubber sheet 3B2 having a concavo-convex shape for preventing slippage due to the attached rotation. As a result, when the entire apparatus 1 is moved forward, the roller portion rotates, and at this time, the roller portion is configured to be in contact with the upper surface of the turf with a sufficient surface pressure.

As described above, when the roller portion 3B is rotated as shown in FIG. 4, the chain 3B3 connected to the roller shaft moves, and the cam shaft 3B41 connected to this chain is rotated to rotate the cam 3B4. The cam 3B4 is in contact with the cutter lever 3A11 via the lever 3B5 with the shaft 3B51 as a fulcrum. Further, one roller of this lever 3B5 is in contact with the cam 3B4.

Therefore, the cutter lever moves up and down by the rotation of the cam, and finally the cutter body 3A2 moves up and down. The shape of the cam 3B4 corresponds to the length of the grass in one rotation. That is, the cam has a half-moon shape, and is processed so that the circular arc portion formed on the cam corresponds to the length of the grass to be cut. Therefore, the length of the grass can be changed by changing the shape of the cam 3B4.

When the cam 3B4 rotates, the arc portion of the
When the roller of the lever 3B5 comes, one of the levers rises and the cutter lever 3A11 remains raised upward until the arc is cut. Further, when the cam rotates and disengages from the arc portion, the roller of the lever becomes free, the lever hits the stopper 3B52, the cutter lever lowers at a dash due to the returning force of the spring 3A3, and the cutter body 3A2 cuts the grass. become. In this case, since the cutter body descends and the body frame continues to move even after cutting the grass, if the cutter body is left as it is, the next grass will be damaged. It is configured to smoothly fall in the opposite direction.

The rear cutter portion 3C is a gate-shaped lever 3C1 suspended from the main body frame 2 so as to be swingable back and forth with a shaft 3C11 as a fulcrum, and a left and right width attached to the lower end of the lever 3C1 with a forward direction. It is composed of a cutting cutter 3C2 and a bottom cutting cutter 3C3 stretched between these cutters 3C2. Use the left and right width cutters 3C2 to cut grass.

The lower end of the gate-shaped lever 3C1 and the motor M provided above the body frame 2 are composed of a crank 3C13 and an intermediate shaft 3.
It is connected via C12. The shaft center of the intermediate shaft 3C12 of the crank 3C13 is eccentric. Therefore, when the motor M is rotated, the cutter swings back and forth. As a result, referring to FIG. 4, when the motor M rotates, the lever 3C1 moves in the front-rear direction to cut the lawn.

The mud-removing lever 3D has a rear cutter portion 3
An appropriate number of the bottom cutting cutters 3C3 at C are continuously provided in a direction parallel to the traveling direction of the main body frame 2. The turf guide plate 3E attached to the mud-removing lever 3D is
A turf guide plate that has been cut, and the turf guide plate is the main frame 2
Installed on.

The above series of operations will be described. First, the motor M is operated to operate the rear cutter portion 3C. next,
When the body frame 2 is moved forward, the roller portion 3B rotates and the cam 3B4 also rotates. The cutter lever 3A11 moves upward due to the rotation of the cam. Further, when the body frame 2 moves, the cutter lever 3A11 descends, and the cutter body 3A2 cuts the grass. After cutting the cut grass, the dirt on the grass bottom is dropped by the movement of the mud-removing lever 3D at the rear, and the grass moves to the rear through the grass guide plate 3E.

With reference to FIG. 3, the conveyor section 4 comprises:
The plate 4A is disposed between the rear end of the turf guide plate 3E and the rear end portion of the main body frame 2 so as to act rearward, and the plate 4A is hung and stretched at a certain interval to generate a conveying force (anti-slip). Has been done. Therefore, the turf 7 cut into strips by the device portion 3 that cuts to the specified length and width can be removed by the mud-removing lever 3D.
Then, the mud is dropped, and the mud is passed over the turf guide plate 3E, placed on the conveyor section, and sent to the rear.

A device portion 5 for winding the cut grass forms a core of the winding grass provided in front of the upper surface of the conveyer conveyor portion 4 .
A front grass winding device 5A that the core provided immediately behind
And a rear lawn winding device 5B that winds the lawn around the axis . Referring to FIG. 5, front lawn winding device 5A
Is a flat rectangular frame 5A1, a shaft 5A2 penetrating the front part of the frame 5A1 to the left and right, a pipe 5A3 loosely fitted to this shaft, and a suitable number of pawls 5A4 connected rearward to this pipe. A stopper 5A5 fixed through the tips of these pawls, a plate 5A6 stretched in the left-right direction on the rear portion of the frame 5A1, and saw-like irregularities formed on the lower surface of the plate, and the shaft 5A2 Both ends of the are loosely fitted in the vertically long holes 5A7 formed in the side wall 2A of the main body frame 2.

The turf 7 sent in first hangs on the tip of the pawl 5A4, and the tip portion 7A of the turf is rolled up as shown in FIG. The grass cannot be rolled unless this first winding is successful. Therefore, in FIG. 10, if the distance a between the tip of the pawl 5A4 and the upper surface of the conveyor 4 is too large, the upper part of the lawn will only be caught by the tip of the pawl 5A4. Therefore, even if the pawl 5A4 is slightly lifted, the winding cannot be started, and the pawl 5A4 stops at the rear portion of the frame 5A1 and is clogged there. The turf 7 rolls up well when the gap A is set in an appropriate state. According to the experiment, the clearance between the tip of the pawl 5A4 and the upper surface of the conveyor 4 is 2-3 mm.
If it is not so good, the grass cannot be rolled.

In order to stretch the height of the tip of the pawl 5A4 according to the condition of the turf, a vertically long hole 5A11 is opened in the frame 5A1 as shown in FIG. 9, and the pawl 5A4 is supported from below in this hole. It is preferable that the pin 5A12 to be fixed can be fixed at a desired height. If the stopper 5A5 attached to the pawl 5A4 is not provided here, the lawn only bends along the pawl 5A4, and the subsequent lawn winding action becomes impossible. Therefore,
If the stopper does not cover the bottom of the grass, the grass will only bend once and will be sent to the rear without being rolled. As shown in FIG. 7, when the bottom of the lawn hits the curl stopper 5A5, the pawl 5A4 is pushed upward. The grass is sent one after another by the conveyor section 4, so the entire frame 5A1 is lifted. However, since the grass is soft, when the grass is lifted to some extent, the grass becomes a small U-shape due to the feeding of the conveyor section 4.

At this time, at the same time, the turf is removed from the pawl 5A4 and is caught on the plate 5A6 immediately behind it. As described above, the plate 5A6 is formed with saw-toothed concavities and convexities, but if it is a simple plate, it will not be wound well.
The turf that has come into contact with the plate 5A6 is the conveyor 4
Will be sent by, so you will start to wind the turf.
However, as the turf 7 that has started to roll goes to the rear of the frame 5A1 and the diameter increases, the load on the frame decreases. If there is no proper load, the grass will come out backwards in the middle. Therefore, in order to apply an appropriate load, when the plate 5A8 is attached to the upper rear part of the frame 5A1 and the grass becomes about one turn,
The rear of the frame 5A1 and the front of the frame 5B1 are overlapped with each other so that the load of the frame 5B1 comes into contact with the frame of the conveyor frame 5B1 on the rear side and the number of windings increases so that the grass is properly wound. . In the front turf winding device 5A, the turf moves backward by about 1 to 2 rolls and is further fed to the rear turf winding device 5B.

Referring to FIG. 2, the rear lawn winding device 5B is
A frame 5B1 formed in a U-shape toward the front of the plane, a power shaft 5B2 penetrating left and right through a tip portion of the frame 5B1, and a conveyor 5 provided in the frame 5B1 using the shaft.
B3, a lever 5B4 rotatably connected to both ends of the power shaft, and a shaft 5B5 projecting from the rear end of the lever. The shaft 5B5 is connected to the side wall 2A of the body frame 2 as a fulcrum. The power shaft 5B2 is loosely fitted in an arcuate elongated hole 5B6 formed in the side wall 2A of the main body frame 2, and the central portion of the frame 5B1 is suspended by a tension spring 5B7 between itself and the main body frame 2. The conveyor 5B3 is incorporated in the frame 5B1 and is not fixed. Therefore,
The front of the frame 5B1 moves up and down in the range of the long hole 5B6. On the other hand, the back is not supported by anyone.

However, if the load of the conveyor 5B3 is excessively applied to the rolled grass, the grass is not rolled and the load is large, so that the grass moves in the rotating direction of the conveyor 5B3 and the frame 5B1.
Get caught in. For this reason, the tension spring 5B7 described above is stretched so as to provide proper operation and reduce the load as the winding diameter increases.

The conveyor 5B3 is driven by a reduction motor 5B8 mounted on the main body frame 2 and an intermediate shaft or chain attached to the outside of the main body frame 2 for transmitting rotation to one of the levers extending from the intermediate shaft. A conveyor shaft is attached and driven by the chain 5B9 from the intermediate shaft. And both of these devices 5A,
5B is arranged so that the front end of the device 5B overlaps the upper surface of the rear end of the device 5A. In addition, the rotation direction of the conveyor 5B3 in the device 5B is the same as the rotation direction of the conveyor section 4. For this reason, the moving direction of the lower surface of the conveyor 5B3 and the moving direction of the lower surface of the conveyor section 4 are opposite to each other, so that the remaining lawn can be well wound and taken out backward.

The operation will be described together with the effect.

[0025]

Since the present invention is configured as described above, it has the following effects. 1. It is possible to save labor in cutting and wrapping turf. That is, in the case of a grass floor of 500 m ^{2 in} the related art, the work performed by five people can be performed by two people. 2. Working time can be shortened. That is, conventionally, in the case of a grass floor of 500 m ² , it took 3 to 4 hours, but it can be completed in about 30 minutes. 3. Conventionally, when moving a work place, various tools have been mounted on a carrier vehicle and moved, but in the present application, the entire apparatus can be moved as it is.
