Abstract
A device for cleaning stubble on the surface of a land before sowing, which is suitable for a no-tillage sowing machine, mainly comprises a gear box, an upper suspension, a connecting frame, a sowing and fertilizing device mounting frame, a stubble cleaning cutter roller and a lower suspension. Wherein, the gear box, the upper suspension, the connecting frame, the seeding and fertilizing device mounting frame and the lower suspension are fixedly connected. The gears in the gear box are arranged in an inverted V shape, three-stage gears are arranged on two sides of the gear box respectively for transmission, the third-stage gears are fixedly arranged with the cutter shaft and can be rotatably arranged on the box body of the gear box through a bearing, and the stubble cleaning cutter roller is fixedly arranged with the cutter shaft. The device transmits the rotation power of the tractor to the stubble cleaning cutter roller through the gearbox to enable the stubble cleaning cutter roller to rotate actively, so that the lateral cleaning of the ground surface stubble is realized. The inverted V-shaped gear box is adopted for transmission, so that the working reliability of the device is improved, and meanwhile, the gear box has the function of a main body frame, so that the structure is simplified, and the maintenance and the repair are convenient. The stubble cleaning knife roller adopts a cantilever beam structure, the longitudinal size of the device is reduced, the longitudinal stability of the whole machine can be effectively improved, the bearing only bears the force generated by stubble cleaning of the stubble cleaning knife roller, the ditching and fertilizing device is not influenced by the force, and the service life of the bearing can be effectively prolonged.
Description
Technical Field
The utility model belongs to agricultural machinery, and mainly relates to a ground surface stubble cleaning device matched with a no-tillage seeder.
Background
At present, the stubble cleaning is needed when the quantity of the stubble is large in the no-tillage seeding operation of the original stubble field, and the phenomenon that the seeding quality is reduced and the crop yield is influenced due to the blockage of the soil contact part of the no-tillage seeding machine is avoided. The stubble cleaning device which is suitable for the no-tillage planter to realize compound operation is mainly divided into an active mode and a passive mode, and the active mode effect is superior to the passive mode. The active stubble cleaning device is divided into a forward rotation type, a reverse rotation type and a side rotation type according to the movement mode of the stubble cleaning component, wherein the side rotation type can realize no stubble covering on the ground surface and soil and straw mixing in the no-tillage seeding process, and has the advantages of small soil movement amount, low power consumption, capability of seeding seeds into a humid soil layer and the like. However, the side-rotating stubble cleaning device matched with the no-tillage planter at present has larger structure size and poorer longitudinal stability of the machine; chain transmission is adopted, so that the operation environment is severe, and the reliability of chain transmission is low; the stubble cleaning knife roller adopts a simply supported beam structure, the bearing is stressed and seriously abraded, and the matching of the side-rotating type stubble cleaning device and a power machine, the working stability and the working efficiency are seriously influenced.
Disclosure of Invention
The utility model aims to solve the problems in the prior art, and researches and designs a device for cleaning stubble on the surface before sowing, which is suitable for a no-tillage sowing machine, so as to reduce the longitudinal size of the machine, improve the reliability of a transmission system, prolong the service life of a bearing, and further improve the working reliability and the working efficiency of stubble treatment and no-tillage sowing.
The basic design of the utility model is to change the transmission system of the stubble cleaning knife roller from chain transmission to gear box transmission, thus improving the environmental adaptability of the transmission system and simultaneously reducing the failure rate of the transmission system in the working process. The stubble cleaning knife roller is designed into a cantilever beam structure, so that the longitudinal structure size of the stubble cleaning device is reduced on one hand, and the seeding and fertilizing device has no additional tension on the other hand, so that the axial and radial loads of the bearing are greatly reduced, the service life of the bearing can be effectively prolonged, and the overall working reliability of machines and tools is improved. The specific implementation scheme is as follows: a device for cleaning stubble on the surface of a land before sowing, which is suitable for a no-tillage sowing machine, mainly comprises a gear box, an upper suspension, a connecting frame, a sowing and fertilizing device mounting frame, a stubble cleaning cutter roller and a lower suspension. Wherein, the gear box, the upper suspension, the connecting frame, the seeding and fertilizing device mounting frame and the lower suspension are fixedly connected. The gears in the gear box are arranged in an inverted V shape, three-stage gears are arranged on two sides of the gear box respectively for transmission, the third-stage gears are fixedly arranged with the cutter shaft and can be rotatably arranged on the box body of the gear box through a bearing, and the stubble cleaning cutter roller is fixedly arranged with the cutter shaft. The device transmits the rotation power of the tractor to the stubble cleaning cutter roller through the gearbox to enable the stubble cleaning cutter roller to rotate actively, so that the lateral cleaning of the ground surface stubble is realized. The device is of a combined structure, can realize the compound operation of stubble cleaning and no-tillage seeding, and can simultaneously carry out the stubble cleaning operation independently.

1. gear box 2, upper suspension 3, connecting frame 4, seeding and fertilizing device mounting frame 5, stubble cleaning knife roller 6, lower suspension 7, gear box body 8, gear 9, bearing 10, power input shaft 11 and cutter shaft
Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The utility model provides a before-sowing surface stubble cleaning device who adapts to no-tillage seeder, mainly by gear box 1, go up hang 2, link 3, seeding fertilizer injection unit mounting bracket 4, clear stubble rotor 5 and hang 6 down and constitute, wherein, gear box 1, go up hang 2, link 3, seeding fertilizer injection unit mounting bracket 4, hang 6 fixed connection down. The gear box 1 is composed of a gear box body 7, gears 8, bearings 9, a power input shaft 10 and a cutter shaft 11, the gears 8 are in inverted V-shaped arrangement three-level gear transmission, the first-level gears 8 and the third-level gears 8 are fixedly installed with the power input shaft 10 and the cutter shaft 11 respectively and are rotatably installed on the gear box body 7 through the bearings 9, and the stubble cleaning cutter roller 5 is fixedly installed with the cutter shaft 11 through a cantilever beam structure.
During operation, a rear power output shaft of the tractor is connected with a power input shaft 10 of the device through a universal joint, power is transmitted to the gear box 1, the stubble cleaning knife roller 5 is driven to rotate through the transmission of a gear 8 in the gear box 1, the stubble cleaning knife roller 5 continuously rotates to crush and convey surface stubbles, the working width is laterally thrown out, and a good stubble-free seedbed environment is created for seeding and fertilizing operation.
