[Industrial (Field 11)] The present invention relates to a lawn spreading machine for creating a lawn by laying cut grass in the shape of a pine tree, which is formed into a predetermined shape such as a rectangle, on the ground. When the cut grass stored in the cut grass storage section of the traveling machine is stacked vertically on the ground, it retracts when moving toward the cut grass group, and when the hook section moves toward the chute, it moves upward into the cut grass. By providing a claw that can be maintained in a working position that bites in from the outside, the feeding device is constructed so that the cut grass at the top of the grass storage section can be continuously supplied to the entrance in a hooked and conveyed state by reciprocating the hook part. Characteristic configuration: [0007] [Operation] According to the above configuration, the cut grass stored in the grass storage unit is delivered to the receiving opening of the chute by the feeding mechanism configured by reciprocating the hook portion provided with the claw. [0008] Then, in order to configure the feeding mechanism, it is possible to maintain the working posture of biting into the cut grass from above when moving in the direction toward the chute. It can be realized with a relatively simple structure since it is only necessary to reciprocate the hook part provided with the claw. Because self-shape retention cannot be expected, it is not possible to carry a rectangular wooden board by grasping only its edges, for example.
By focusing on the ability to easily pierce plowing claws, chopstick-shaped sticks, etc., we developed a chute for guiding and sliding feeding, making it possible to adopt a conveyance method that uses dragging movement due to the biting of the claws to change the posture. The present invention relates to a turf dispensing device for a turf spreader in which a traveling machine body is connected to a supplying device for sequentially laying the cut grass conveyed from the chute on the ground. [0002]

2. Description of the Related Art The above-mentioned lawn mowing machine has a wheel-running chute that feeds cut grass downward to the ground, as shown in Japanese Patent Application No. 1-316888, which was previously filed by the present applicant. A lawn mowing machine installed at the rear of the aircraft has been proposed. [0003]

[Problems to be Solved by the Invention] It is stated that in the structure of the lawn spreading machine according to the above proposal, the cut grass stored in the grass storage section is continuously supplied to the receiving opening of the chute by manual operation. It was something that existed. [o o 04] However, this would require a dedicated worker for the turf supply work in addition to the operator of the aircraft, and the supply work, which seems to be a relatively monotonous cycle, would be labor-intensive. Deafness is expected. [00051] In view of the above prediction, an object of the present invention is to mechanize the work of supplying cut grass from the grass storage section to the chute. [0006]

[Means for Solving the Problems] The present invention provides the turf spreading machine described at the beginning, in which a hook portion is provided which is movable back and forth between the upper position of the turf storage part and the upper position of the cut turf supply inlet of the chute. The hook was set at 5θ. [00101

[Effects of the Invention] As a result, it was possible to realize a feeding device for a lawn mowing machine that can mechanically and continuously supply cut grass from the grass storage section to the receiving opening of the chute with a relatively simple structure. DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings. [00111 As shown in FIG.
A turf storage device 4 and a turf loading platform 5 are arranged on the machine body 3 having a turf storage device 4 and a turf loading platform 5 on the rear side of the driving unit 2, and a feeding device A has four rows of turf supply chutes 6 lined up in the lateral direction of the machine body. The aircraft 3
Attached to the rear of the lawn mower, so that 4 rows of grass can be laid at the same time.
In addition, the lawn mowing machine is constructed so as to be able to travel with steering front wheels 7 and driving rear wheels 8. [0012] The storage device 4 is stacked in 10 stages to form a bundle. A pedestal 10 on which a large number of cut grass 9 is placed in two rows, front and back, is stacked inside a frame 11. The turf storage device 4 is configured so that it can be raised and lowered by a lifting device 15 consisting of the following. Also, a start switch 17 automatically stops the extension movement of the hydraulic cylinder 12 when it comes into contact with the cut grass 9 on the upper stage, and causes the hydraulic cylinder 12 to extend and move the support platform 10 up when it does not come into contact with anything. is provided on the frame 11 so that the cut grass 9 at the top level always automatically returns to a constant height position. [0013] This lawn mowing machine is provided with a feeding mechanism 14 for sequentially supplying the cut grass 9 stored in the grass storage device 4 to the receiver of the chute 6 and the o19, and the work of boarding the machine is The structure is such that the operator can handle all the necessary tasks. [00141 As shown in FIGS. 3 and 4, the feeding mechanism 14 includes a swinging arm 1 having a hook 16 at the tip.
8. Hydraulic first cylinder 2 that drives and oscillates this arm 18
5, a support plate 26 that supports both of these 18.25;
It is composed of a four-link mechanism 28 that raises and lowers the support plate 26, and a second hydraulic cylinder 29 that drives this link mechanism 28. [0015] The swinging arm 18 is constructed by attaching a third hydraulic cylinder 31 having a hook 16 at the tip of a movable rod 30 to a base plate 32. [0016] As shown in FIG. 5, the hook portion 16 is
U-shaped case portion 33 attached to the tip of the movable rod 30
When the hook part 16 moves in the direction toward the cut grass group G, it moves backward, and when the hook part 16 moves in the direction toward the chute 6, it is designed so that it can be maintained in the working position of biting into the cut grass from above. A claw 27 is provided which can swing freely around the horizontal axis X within a range. [0017] Next, the function of this feeding mechanism 14 will be explained. It is something that can be expected. [00221Figure 1. As shown in the figure, the chute 6 and the transport mechanism B, the ground leveling mechanism C, etc. provided at the lower end of the chute are connected to the machine body 3 so as to be able to rise and fall by a rear link mechanism 20 consisting of a lower arm 20a and an upper arm 20b and a hydraulic cylinder 21. The supply device A is configured as follows. 1θ [0023] As shown in FIG. 2, the transport mechanism B includes a rotating body 22 and an electric motor 2 that drives and rotates the rotating body 22.
3, an arm member 34 supporting the rotating body 22 is pivotably pivoted about two horizontal axes, and is biased upward by a spring 35 to reduce the downward biasing force due to its own weight. . [0024] The rotating body 22 has a large number of protrusions 22a on the outer periphery.
The protrusion 22a is placed close to the cut grass 9 on the sliding surface 6b of the shoe l~ so that it bites into the cut grass 9, and the electric motor 23 is not energized for rotation. The cut grass 9 is forcibly transferred toward the guide tool 24 by the driving rotation of the body 22 in the radial direction of the arrow, and the cut grass 9 is transferred to the shoe 1 by stopping the rotation.
It remains locked at the lower end position. [0025] Example according to C]. [0018] As shown in FIG. 3, when taking out the cut grass 9 from the 9 bundles of cut grass on the rear side, the second cylinder 29 is extended to bring the support plate 26 to the raised position, and the third cylinder 3
1 to reduce the swing diameter of the swing arm 18. Then, by driving the first cylinder 25 to expand and contract,
The cut grass 9 in the back row can be automatically supplied to the chute 6. [0019] Then, when the cut grass 9 on the rear side is removed, as shown in FIG.
In other words, the second cylinder 29 is contracted and the support plate 26 is in the lowered position, and the third cylinder 3
1 to increase the swing diameter of the swing arm 18. By driving the first cylinder 25 to extend and retract, the cut grass 9 in the front row can be automatically supplied to the chute 6. [00201 When the cut grass 9 on the front side is transferred and the start switch 17 is activated, the lifting device 15 is activated and the platform 10 is raised by the amount of the cut grass minus the crest needle, and the cut grass 9 on the rear side is transferred again. It is ready to be taken out. By repeating this series of operations, the cut grass 9 can be continuously supplied to the chute 6. The hook part] 6 may be supported by belt conveyor-type feeding mechanisms 1 and 4 installed in the front-rear direction so that it can be moved back and forth. [0026] Note that although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure of the attached drawings by the entry.
