Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grass collecting structure for a grass cutter.

Conventionally, when cutting grass with a rotary cutting blade, the cut grass scatters and requires a lot of effort and time for subsequent harvesting work.

The present invention aims to provide a grass-collecting structure for a grass cutter, in which the grass cut by a rotary cutting blade is successively collected at a fixed location, which is convenient for later harvesting work.

An embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a bearing cylinder. A rotating shaft 2 is inserted into the bearing cylinder 1, and a cap-shaped disc 3 is attached to the lower end of the rotating shaft 2. A required number of reaping blades 3 are provided on the outer periphery of the cap-shaped disk 3.

5 is a screw chain for attaching the reaping blade 4.

A guide plate 6 is provided in the bearing tube 1, and the guide plate 6 guides the direction of rotation of the reaping blade from the center of rotation of the cap-shaped disk 3 on which the reaping blade 4 is installed, that is, from the vicinity of the rotating shaft 2. It is formed into a convex curve that gradually separates from the center of rotation toward the center of rotation and protrudes forward in the direction of movement of the work equipment. The mounting structure is gradually eccentric from the reaping direction A and extends laterally toward the disk rotation direction B, and has a shape similar to a spiral. Furthermore, the terminal end of the transfer plate 6 is protruded outward from the rightmost end in the cutting direction of the outer periphery of the cap-shaped disc 3, and is opposed to the lateral side of the protruding portion as described below. A grass collection board 7 is provided.

Reference numeral 7 denotes a grass collection plate, which is extendable and retractable with a grass collection plate holding cylinder 9 and a push screw 8 that protrudes laterally from the bearing cylinder 1, and a certain space from the aircraft body at the end of the transfer plate 6. It is arranged on the side of the machine to hold S, and is composed of a longitudinal plate of a certain height, and collects the cut grass guided by the guide plate 6 at a certain position. It is for.

10 is a pulley provided at the upper end of the rotating shaft 2; 11' is a mounting hole for mounting a separately provided working machine (not shown);
Reference numeral 12 denotes a belt suspended from one pulley, which extracts power from the work machine and transmits the power to the rotating shaft 2.

a is the growing grass before cutting, b is the cut grass,
c shows grass collected and arranged in a row.

The embodiment of the present invention is constructed as described above, and when power is transmitted to the rotating shaft 2 via the belt 13, the cap-shaped disk 3 is rotated and the grass a is cut by the cutting blade 4. The cut grass b is intended to be scattered in the disc rotation direction B, but the wind pressure due to the movement of the aircraft, the wind pressure due to the scattering of the grass, and the cap-shaped disc 3 and The wind pressure when the cutting blade 4 rotates forms an air flow along the outer circumferential surface of the upper guide plate 6, so that the cut grass b quickly passes along the outer circumferential surface of the guide plate 6. The grass is collected in the direction of the terminal end, and the cut grass transferred to the terminal end is blocked by the inner surface of the grass collecting plate 7 located on the outside of the terminal end, and accumulates in the space S. In particular, since the end of the guide plate protrudes outward from the rightmost edge of the outer circumference of the disc 3 in the cutting direction, the cut grass collected along the outer circumferential surface of the guide plate is ensured to reach the outer circumference of the disc 3. Disk 3 is discharged to the rightmost outer side in the cutting direction.
The grass cut in this way is guided one after another by the transfer plate 6, and is collected on the side of the machine to prevent it from being eaten by the grass.
The grass collects in the space S between the fuselage and the grass collector plate 7, and is reliably collected on the sides of the fuselage.

According to this invention, the cut grass is guided toward the grass collecting board along the guiding board without scattering in multiple directions, and is accurately collected at a fixed position by the blind grass board. This has the effect of making work easier and faster.

Claims (1)

[Claims] 1 A reaping blade that reaps grass while rotating is installed on the outer periphery of a rotatable disc, and the reaping blade is gradually eccentric in the direction of rotation of the reaping blade and in front of the center of rotation in the direction of movement of the work equipment. A guide plate is fixedly installed, which has a convex curve that protrudes toward the outer circumference of the disk, and whose terminal end is on the outer side of the outer circumference of the disk than the rightmost end in the cutting direction, and which protrudes from the side of the machine. A grass-collecting structure for a grass cutter in which a grass-collecting plate is placed on the side of the terminal side while maintaining a certain space from the machine body.
