A long and short knife combined elastic type seed tape cleaning device

Abstract

The invention relates to a long knife and short knife combined elastic type seed zone cleaning device. The long knife and short knife combined elastic type seed zone cleaning device comprises a power transmission device, a knife shaft device and a stubble cleaning and carding device, wherein the power transmission device comprises a shaft cup cover (1), a shaft cup (2) and a shaft head (3), a gear positioning sleeve (4) and a deep groove ball bearing (5), wherein the knife shaft device comprises a knife shaft pipe (6); the stubble cleaning and carding device comprises a cutterhead (14), a short bolt (7), a first thin nut (12), a long bolt (13), a second thin nut (8), a spring (9), a stubble cleaning knife (10) and a straw carding device (11). The device provided by the invention is mounted in front of furrow openers; long straws can be cleaned into a space between two lines of furrow openers while the stubble cleaning knife is used for cleaning straw stubbles; the straw carding device does not enter soil so that the resistance is reduced; the device is used for cleaning the straws while being used for directly cleaning the stubbles, so that power consumption is reduced and no-tillage seeding under large coverage of the straws can be realized; conditions that seeds are aired and are not uniformly sowed do not occur; the device is applicable to a corn no-tillage seeding machine and further popularization of protective tillage is easy to promote.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a long-short-knife combined elastic seed belt cleaning device. Background technique [0002] Conservation tillage is an agricultural farming method that implements no-tillage and less tillage to reduce soil tillage, covers the surface with crop straw and stubble to reduce soil wind erosion and soil erosion, and improves soil fertility and drought resistance. [0003] At present, the common conservation tillage devices are mainly no-tillage seeders. However, when the no-tillage seeder is operating on a field covered with a large amount of straw, the adjacent openers are prone to blockage, which often causes the equipment to fail to work normally. In addition, after sowing on a field with a large amount of straw Too much straw may cause seeds to dry out and uneven sowing to affect seedling emergence. To sum up, the no-tillage seeder is required to have ...

Problems solved by technology

[0006] However, the above two anti-blocking parts can not penetrate into the soil, and the speed is low, but the anti-blocking ability is poor. When the amount of straw is covered, the straw that is shifted to both sides is easy to block between adjacent openers.
