Description

[Detailed explanation of the idea]

[Industrial Application Field] This invention relates to a rotary grass collector used for management work of mowing planted lawns on the slopes of river embankments and collecting the cut grass. [Conventional technology] Managers of Class 1 and 2 rivers across the country plant lawns on the slopes of river embankments several times a year to strengthen the roots of the grass and protect the slopes in preparation for disasters caused by rising waters. Perform mowing of cultivated lawn. At that time, in urban areas and surrounding areas, for the purpose of environmental hygiene and environmental beautification, grass clipped from the top of the embankment to the slope management width is collected and incinerated or transported for disposal. However, if large heavy machinery is placed on the slope to collect grass, there is a risk that the large heavy machinery will topple over due to the steep slope, and the slope will collapse due to the pressure of the large heavy machinery, so all grass collection work is done manually. ing. Therefore, there is a need for a lightweight machine capable of collecting grass on steep slopes of this type. [Problems to be solved by the invention] The purpose of this invention is to provide a lightweight machine that can safely collect grass on steep slopes as requested above without causing the slope to collapse. [Means for Solving the Problems] The present invention will be explained below with reference to drawings. In a self-propelled work machine, (a) the machine body has three points: 12 traveling drive wheels and 41 free wheels; A motor 13 with a transmission 14 is mounted, and handles 8 are attached to the front and rear. (b) Support rods 3, 3 are installed horizontally on the front and back of the fuselage, and a fixed ring 9 is formed at the tip of the support rods in an annular shape around the fuselage.
are fixed in two stages, upper and lower. (c) Attach the required number of pedestals 11, each of which has support rollers 30 and guide rollers 6 horizontally and vertically pivoted, to the outer periphery of fixed ring 9, dividing them into equal parts. (d) A rotating ring 12 having a vertically rectangular cross section is formed, a rack gear 27 is provided on the inner periphery, the lower surface of the rotating ring 12 is supported by a support roller 30, and the outer peripheral surface of the rotating ring 12 is guided by a guide roller 6 and fixed. It is attached concentrically with ring 9. (e) Add a step to the top and bottom of the first half and the second half of the ring with a rectangular cross section, and connect them smoothly to form the upper stage 1.
A undulation guide wheel 10 divided into a lower stage 0a and a lower stage 10b is formed and fixed concentrically to the outer periphery of a fixed ring 9 via a pedestal 11. (F) Connect one end of the required number of crankshafts 26 to the rotating ring 12.
The guide rollers 25a, 25a and 25a are divided into equal parts on the upper outer periphery and are rotatably mounted on bearings 22, and the grass collecting claw 2 is fixed to the other end, and the guide rollers 25a, 25a are spaced vertically with the undulation guide wheel 10 sandwiched between the vertical parts in the middle. 25b is provided. (G) The pinion gear 21 fixed to the gearbox 5 shaft 28 is engaged with the rack gear 27, and the V-belt 16 is applied to the prime mover 13 and gearbox 5. It is configured as above. [Operation] When the rotary wheel 12 is rotated by transmitting power from the prime mover 13 of the rotary grass collector configured as described above to the V-belt 16, the gear box 5, the pinion gear 21, and the rack gear 27 in this order, the crankshaft 26 attached to it rotates. Kusatsume 2 rotates together. The undulating guide roller 25a of the crankshaft 26 comes into contact with the lower part 10b of the undulating guide wheel 10, so that the crankshaft 26 becomes upright, and the grass collecting claws 2 act on the grass. When the crankshaft 26 further rotates, the undulating guide roller 25b comes into contact with the upper stage 10a of the undulating guide wheel 10, and the crankshaft 26 rotates horizontally around the bearing 22, causing the grass collecting claw 2 to idle. Therefore, the grass collecting claw 2 acts on half the circumference in the direction of movement,
During the other half of the rotation, the grass collecting claw 2 rotates idly, raking grass, etc. to one side and collecting the grass. Through this continuous action, it moves forward along the embankment and collects grass, etc. from the slope in one direction (downward from the slope). At the working end, the machine moves in parallel and backwards, and then reciprocates to collect grass in the same direction. After operating the transmission 14 to move forward or backward, the operator stands at the rear side in the direction of movement of the machine, holds the handle 8, and operates the machine while walking as the machine moves. For reference, the table below shows an example of comparing the grass collection efficiency per hour.

[Effect of idea]

With the above configuration, the machine body (center of gravity) is located at the center and is lighter than large heavy equipment, so it is stable on steep slopes and can safely collect grass without causing the slope to collapse.
