Description

[Detailed Description of the Invention] The present invention relates to a crushing roller in a grass cutting and adjusting machine that cuts grass in a pasture field with a cutting body and crushes and adjusts the grass with a pair of crushing rollers.

The present invention will be explained below with reference to the drawings.

asb indicates a pair of crushing rollers, and this crushing roller has a hard elastic body 2 attached to the outer peripheral surface of a cylindrical body 1.

On the surface of the elastic body 2, a large number of spiral protrusions 3 and a large number of spiral grooves 4 are formed in opposite directions from the starting end X of the cylindrical body 1 to the first half circumference and the second half circumference, respectively. The pair of crushing rollers atb are arranged one above the other in the casing 5 so that the protrusion 3 of one crushing roller and the concave groove 4 of the other crushing roller engage with each other.

Reference numeral 5 denotes a casing with open front and rear surfaces, and on the bottom of the casing 5 there is a cutting body 8 for cutting grass in a pasture field.
A pair of crushing rollers awb are arranged above and below in the casing 5 behind the crushing rollers awb, and a drive shaft 6 is provided on the side wall of the casing 5, which is provided at the center of both ends of the cylindrical body 1 of each of the crushing rollers a and b. It is supported by a bearing 7.

Reference numeral 9 denotes a guide plate for transferring the grass cut by the cutting body 8 to a pair of upper and lower crushing rollers a, b. Above the cutting body 8 and the guide plate 9, a pair of crushing rollers a, b
A scraping body 10 for feeding between the two is pivotally supported on the casing 5,
A gauge shoe 11 is provided at the rear of the cutting body 8 to adjust the height of the cut grass of the cutting body 8.

12 is a tow bar attached to the front of the casing 5; the tow bar 1
2 and parallel to the universal joint 13 on the casing 5.
The universal joint 13 transmits the power of a motor vehicle that pulls the casing 5 to the universal joint 13, and the motive power drives the raking body 10, the mowing body 8, and the crushing rollers a9b.

A substantially gate-post-shaped support frame 14 is arranged at the rear of the casing 5, and a pair of left and right upper links 15 connected to the rear upper end of the casing 5 are connected to the upper part of the support frame 14 and connected to the lower rear bottom of the casing 5. A pair of left and right lower rings 16 are connected to the lower part of a support frame 14, and a pair of wheels 17 are pivotally supported at both lower ends of the support frame 14.

A hydraulic cylinder 18 is connected to the lower link 16 and lifts and supports the lower link 16 by expanding and contracting the hydraulic cylinder 18.

Reference numeral 19 denotes a swing spring that applies a pulling force to the grass cutting and crushing work body to the support frame 14, thereby reducing the grounding force of the work body.

Next, its effect will be explained.

The traction rod 12 of the casing 5 is connected to a power vehicle, and the reaping body 8. Scraping body 10. - drive the crushing rollers asb of the casing 5. When the support frame 14 is pulled by a motor vehicle into a grass field, the grass is cut by the cutting body 8 and the grass is cut by the raking body 8. A pair of crushing rolls a and b are guided by the guide plate 9.
The cut grass is crushed by being sent between them.

The crushed grass is placed on the rear almost gatepost-shaped support frame 14.
Adjusted pasture ridges with appropriate air gaps are formed.

The crushing roller has a large number of spiral protrusions 3 and concave grooves 4 on the surface of a hard elastic body 2 attached to the outer peripheral surface of the cylindrical body 1 from the starting end X of the cylindrical body 1 to the first half and the second half of the circumference. They are formed in opposite directions to the circumference, and arranged so that the protrusion 3 of one of the pair of upper and lower crushing rollers a and b is engaged with the concave groove 4 of the other crushing roller, so that the crushing rollers are driven and rotated. When the grass is fed between the pair of crushing rollers a) and b, the parallel surfaces of the starting ends X of the projecting parts 3 engage with each other, as shown in FIG. Grass violet is folded and fed in the length direction (longitudinal direction), crushed on the surface of the protruding part 3 and the groove part 4, and the fibers of the grass violet are crushed on the surface of the spiral wall where the protruding part 3 and the groove part 4 join. The hay is torn in a direction perpendicular to the direction of the grass, and the hay is completely crushed, resulting in uniformly prepared hay.

In addition, since the spiral protrusion 3 and concave groove 4 of the crushing roller are formed in opposite directions from the starting end X of the cylindrical body 1 to the first half circumference and the second half circumference, the direction in which grass is released after being crushed is is balanced and the driving force is not biased.
The shape of the ridges of the released grass is also uniform on the left and right sides, making it possible to carry out post-work smoothly.
