Description
Technical Field
The invention belongs to the technical field of agricultural machinery, and particularly relates to a long and short cutter combined elastic belt cleaning device.
Background
The protective cultivation is an agricultural cultivation method which can implement no-tillage and less-tillage on farmland to reduce soil cultivation, and can be used for covering ground surface with crop straw and residual stubble to reduce soil wind erosion and soil erosion and raise soil fertility and drought-resisting capacity.
The current common protective tillage device is mainly a no-tillage planter. However, when the no-tillage planter works on a land covered by a large amount of straws, because the adjacent furrow openers are easy to block, the machine tool can not work normally, in addition, the straws are planted on the land covered by a large amount of straws, and then the seeding is not uniform, and the seedling emergence is possibly influenced. In view of the above, no-tillage planters are required to have better belt cleaning performance. In order to solve the problem of blockage of the existing machine tool, an anti-blocking device is generally required to be added on the seeder.
The invention discloses a no-tillage corn seeder capable of fully crushing straws (patent No. ZL200520112559.X), which can complete operations of crushing straws, fertilizing, seeding, compacting and the like by one-step advancing by adding a straw crushing device in front of a seeding device of the no-tillage seeder. But the device needs to rotate at a high speed to break sundries and straws when working, thereby greatly increasing the power consumption of the machine.
The invention discloses a horizontal active grass poking wheel anti-blocking device (patent No. ZL200810225478.9), which is used for poking straws in front of a furrow opener to two sides of the furrow opener in a mode of installing a horizontal grass poking wheel in front of the furrow opener so as to prevent blockage. The invention relates to an active reciprocating type no-tillage anti-blocking unit body (patent number: ZL 200810225477.4), which prevents blocking by arranging a shifting finger which rotates from bottom to top in front of a shovel handle of a furrow opener to shift straws in front of the shovel handle of the furrow opener to a row.
However, the two anti-blocking components can not enter the soil, the rotating speed is low, but the anti-blocking capability is poor, and when the straw amount is covered greatly, the straw which is pulled to two sides is easy to block between the adjacent furrow openers.
Therefore, a long and short knife combined elastic type belt cleaning device which can prevent the blockage of large crop straws and can ensure that sundries such as long straws and the like do not influence the sowing uniformity after sowing is needed.
