Problems solved by technology

[0006] The present invention mainly solves the technical problems that the grass breaking mechanism existing in the prior art is easy to jam the knife, and once the knife jam occurs, it can only be stopped for cleaning, the cleaning process is troublesome, and there are potential safety hazards. The anti-jamming knife and grass cutting mechanism can automatically remove the mud and straw blocked between the fixed blades

Embodiment 1

[0019] Such as figure 1 , figure 2 As shown, the present invention is an anti-sticking knife-breaking mechanism, which includes a grass-breaking bin 5 and a knife roller 1. The knife holder 2 is staggeredly distributed on the knife roller. The knife holder is provided with a knife shaft and the knife shaft is provided with For the grass cutter 3, the cutter shaft is rotatably connected with the grass cutter 3, and there is a clearance fit between the grass cutter 3 and the cutter shaft. The knife roller 1 is connected to a driving motor 7, and the output shaft of the driving motor 7 is connected to the knife roller 1 through a shaft coupling 8. A fixed blade 4 is provided on the lower inclined surface of the feeding inlet of the grass-crushing bin, and the fixed blade is located between the grass-crushing knives 3.

[0020] The grass cutter and the knife shaft are connected by a clearance fit. During the rotation of the knife roller driven by the driving mechanism, the grass cut...

Embodiment 2

[0023] Such as image 3 As shown, the present invention is an anti-sticking-knife grass-breaking mechanism, which includes a grass-crushing bin 5, a knife roller 1, and grass-crushing knives 3 are distributed on the circumference of the knife roller 1. The output shaft of 7 is connected to the knife roller 1 through a coupling 8. The knife roller 1 is provided with knife holders 2 staggeredly distributed. The knife holder 2 is provided with a knife shaft. The knife shaft is rotatably connected with the grass cutter 3, and there is a clearance fit between the grass cutter and the cutter shaft. The grass cutter is provided with a tension spring 6 on one side in the moving direction, and the other end of the tension spring 6 is connected with the knife roller 1. A fixed blade 4 is provided on the lower inclined surface of the feed inlet of the grass-crushing bin 5, and the fixed blade is located between the grass-crushing knives.

[0024] In this embodiment, when the grass cutter ...

Abstract

The invention relates to an anti-knife-jamming grass chopping mechanism. The anti-knife-jamming grass chopping mechanism comprises a grass chopping bin and a knife roll, wherein grass chopping knives are distributed on the periphery of the knife roll; and the knife roll is connected with a driving mechanism. The anti-knife-jamming grass chopping mechanism is characterized in that a plurality of knife holders are arranged on the knife roll, and a knife shaft is arranged on the knife holders; the knife shaft is rotatably connected with the grass chopping knives which are in clearance fit with the knife shaft; and fixed blades positioned among the grass chopping knives are arranged in the grass chopping bin. The anti-knife-jamming grass chopping mechanism has the advantages that the knife jamming does not occur easily, and soil and straws blocked among the fixed blades can be automatically removed.

Description

[0001] Technical field [0002] The invention relates to an agricultural equipment, in particular to a grass shredding mechanism. [0003] Background technique [0004] After the rice is harvested and threshed, if the straw needs to be backfilled into the field, the straw needs to be chopped to facilitate the leveling of the rice field and the next planting. Therefore, existing combine harvesters generally have a grass shredding mechanism. For example, the Chinese patent with publication number CN102273361 discloses a grass cutting mechanism of a harvester, which includes a grass cutting box, a feeding knife roller, a cutting knife roller, and a transmission mechanism. The single-blade cutter body is divided from large to small in diameter. There are several groups. The first group of single-blade disc cutter bodies are evenly arranged on the cutting knife roller, and the next group of single-blade disc cutter bodies are evenly arranged between the two adjacent cutter bodies of ea...
