[0028] The driving sprocket 514 is axially fixedly provided with an output main shaft 504, the output main shaft 504 penetrates all the output main shafts 504 and the internal support frames 507, the output main shaft 504 is rotatably connected with the internal support frames 507, the driving sprocket 514 and the three internal support sprockets 509 are externally meshingly provided with a breaking transmission chain 505, a plurality of breaking sawteeth 506 are fixedly arranged on the outer surface of the breaking transmission chain 505, the internal support frames 507, the driving sprocket 514 and the three internal support sprockets 509 support the breaking transmission chain 505, so that the breaking transmission chain 505 is in a rhombus state and is perpendicular to the ground, the end corners of the breaking transmission chain 505 vertically point to the ground, and the rhombus breaking transmission chain 505 can easily break the ground soil when rotating and cutting the ground, thereby reducing the breaking difficulty of the cold land.

[0029] A plurality of soil shredding blades 511 are also fixed between every two adjacent crushing transmission chains 505, the cross section of the soil shredding blades 511 is an acute triangle, and the soil shredding blades 511 do not contact the intermediate connecting plate 4 when the crushing transmission chains 505 rotate, the soil shredding blades 511 between adjacent crushing transmission chains 505 are used to cut the land cut by the crushing transmission chains 505 again, so that the land soil is more crushed and the straw in the soil is crushed, so that the crushed straw particles are smaller and more easily decomposed.

[0030] An intermediate connecting plate 4 is arranged between every two adjacent crushing transmission chains 505, the side surface of the crushing transmission chain 505 is in sliding contact with the side surface of the intermediate connecting plate 4, the outer surface of the intermediate fixed rod 512 is fixed with two symmetrically distributed fixed connecting rods 8, the top end of the fixed connecting rod 8 is fixed to the ground of the intermediate connecting plate 4, the included angle between the two fixed connecting rods 8 is ninety degrees, the fixed connecting rod 8 and the intermediate fixed rod 512 are integrally cast, the intermediate connecting plate 4 is supported by the fixed end rod 508, and the crushing transmission chain 505 is limited by the intermediate connecting plate 4, so that the crushing transmission chain 505 does not move along the axis direction of the output main shaft 504 during rotation, thereby avoiding the crushing transmission chain 505 from being separated from the driving sprocket 514 and the internal supporting sprocket 509.

[0031] The two ends of the output main shaft 504 penetrate through two end fixed plates 3, the two ends of the output main shaft 504 are rotatably connected to the two end fixed plates 3 through roller bearings, the outer side of one end of the output main shaft 504 is fixed with a transmission gear 503, a output gear 502 is meshingly installed below the transmission gear 503, an output motor 501 is installed in the axial direction of the output gear 502, the output shaft end of the output motor 501 penetrates through the output gear 502 and is connected to the output gear 502 through a fixed pin, a support plate 9 is arranged below the output motor 501, one end of the support plate 9 is fixed to the end fixed plate 3 close to the output motor 501, the output main shaft 504 and the driving sprocket 514 penetrated by the output main shaft 504 are driven to rotate counterclockwise by the output motor 501, the output gear 502, and the transmission gear 503, so that the crushing transmission chain 505 drives the crushing sawtooth 506 to rotate counterclockwise and cuts the land.

[0032] Working principle: first, connect the connecting hanging plate 1 to the lifting structure behind the rotary tiller through a hook, then start the power of the rotary tiller and the output motor 501, after the rotary tiller is started, the lifting structure behind the rotary tiller controls the connecting hanging plate 1 and the mounting bracket 2 to descend, so that the bottom end of the crushing transmission chain 505 slowly approaches the land, at the same time, the output motor 501 is energized and drives the output gear 502 and the transmission gear 503 to rotate, at this time, the transmission gear 503 drives the output main shaft 504 to rotate counterclockwise;

[0033] The output main shaft 504 in rotation drives the drive sprocket 514 penetrated by it to rotate, and the drive sprocket 514 in rotation drives the crushing transmission chain 505 and the crushing sawtooth 506 on the outer surface of the crushing transmission chain 505 meshed with it to rotate counterclockwise. When the crushing transmission chain 505 descends with the mounting bracket 2 and the bottom end is in contact with the ground, at this time, since the crushing transmission chain 505 is perpendicular to the ground, and the crushing transmission chain 505 is in contact with the ground at one end, the crushing transmission chain 505, the crushing sawtooth 506 and the ground are in point contact, so the crushing sawtooth 506 on the outer surface of the crushing transmission chain 505 in rotation first crushes the ground at the vertex, and then through the crushing point, the crushing transmission chain 505, the crushing sawtooth 506 slowly descend into the ground, crushing the ground into regions of the same width. Compared with the traditional crushing method, the crushing transmission chain 505, the crushing sawtooth 506 has lower crushing difficulty.

[0034] When the crushing transmission chain 505, the crushing sawtooth 506 crushes the land into regions of the same width, the crushing transmission chain 505 drives the soil cutting blade 511 to rotate counterclockwise at the same time. The soil cutting blade 511 in counterclockwise rotation turns over and cuts the soil inside the region crushed by the crushing transmission chain 505, the crushing sawtooth 506. The soil cutting blade 511 can cut the straw in the soil synchronously when crushing the soil, and the crushed soil and straw particles are small, so that the straw can better rot and deteriorate and improve the crushing efficiency of the land.

[0035] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments but can be implemented in other embodiments without departing from the scope of the application. The embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims.
