A kind of elastic anti-clay retaining board

Abstract

The invention discloses an elastic soil-sticking prevention soil retaining plate and belongs to the technical field of agricultural machinery. The elastic soil-sticking prevention soil retaining plate is composed of a frame, an upper pulling plate, side plates, a soil retaining plate body, a floating soil scraping plate and floating struts, the upper pulling plate is mounted on the rear beam of the frame in a hinged connection manner, the side plates and the upper pulling plate are fixedly connected through pin shafts, the soil retaining plate is welded on the side plates, the floating soil scraping plate and the pin shafts of the side plates are connected at the lower end of the soil retaining plate, and the floating of the floating soil scraping plate is controlled through the floating studs. When rotary parts of a machine is operated, soil tossed up by a rotary cutter is tossed to an arc block for soil retaining, the arc block performs oscillatory movement to cast off the soil sticking in the arc block, the soil sticking in the arc block is cut up and knocked down by a soil cutter, and the situation that soil sticks in the inner wall of the soil retaining block is improved; the floating soil retaining plate levels the soil at the lower end of the soil retaining plate, so that a good fertilization seeding condition is created; the elastic soil-sticking prevention soil retaining plate is high in safety protection, low in energy consumption, reasonable in structure and suitable for wheat sowing in a rice-stubbed field in a rice and wheat rotation area or farming of rapes.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to an elastic anti-clay soil retaining board. Background technique [0002] In order to simplify the operation procedure, reduce the operation cost and improve the soil quality, the technology of no-tillage sowing wheat on the rice stubble field in the rice-wheat rotation area has been extensively studied. When sowing wheat with no-tillage in paddy stubble land, in order to ensure good soil penetration, stubble breaking and anti-blocking performance of the seeder, the equipment generally adopts strip rotary tillage for ditching and stubble breaking. However, due to the high moisture content and viscous Large, the soil thrown up during the process of breaking stubble and ditching with the rotary tiller is easy to adhere to the inner wall of the soil retaining plate of the machine, and cannot fall off automatically. The more sticky, the thicker it is, which affects the ...

AI Technical Summary

Problems solved by technology

Therefore, it is necessary to design an anti-clay soil retaining board for the problem that the soil thrown up by the rotary tiller is easy to stick to the inner wall of the soil retaining board when wheat is sown in no-tillage on the rice stubble field.
