Rotary tilling and ridging and crawler conveying type whole plastic soil covering machine

Abstract

The invention discloses a rotary tilling and ridging and crawler conveying type whole plastic soil covering machine which comprises a frame, a rotary tilling mechanism, a suspension bracket, a gear box, a transmission mechanism, a soil conveying mechanism, a plastic spreading roller, a plastic hanging bracket, a land wheel, a press wheel and a reshaper and further comprises a soil belt stacking mechanism. The front end of a rotary tilling blade is bended to form an arced working surface so as to crush soil blocks and weed stubbles on the surface of the land for the convenience of conveying the soil. Meanwhile, the soil conveying mechanism is improved and the crawler conveying manner is adopted, so smooth conveying of the soil is ensured, and a crawler structure of the whole plastic soil covering machine can work under high intensity for a long time without breaking, bending or fatigue damage. The whole plastic soil covering machine is added with the soil belt stacking mechanism to match with the soil conveying mechanism, and when the whole plastic soil covering machine goes forward, the soleplate of a soil collecting bin is enabled to open and close at intervals under the actions of the land wheel and a pull spring to cover soil on the surface of the plastic. The amount of the covering soil is even, the covering spaces are well-balanced, and the whole plastic soil covering machine is good in operational reliability, high in integration degree, facilitates the farming work and saves labor.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a rotary tillage and ridge crawler conveying full-laying film-covering machine. Background technique [0002] At present, there have been many kinds of combined operation machines for ridging, fertilizing, and film-covering soil in China. Generally, ditching shovels or wave-type soil conveying mechanisms are used to fetch soil. The first type of machine soil moves backward along the ditching shovel and enters the soil conveying mechanism. , but when the soil moisture content is high, the soil is easily squeezed into clods and cannot be transported backward; and when there are many weeds and stubbles in the field, it is easy to cause the ditch shovel to be blocked, resulting in insufficient or no soil covering on the edge of the membrane. In addition, the soil conveying mechanism is generally equipped with a soil delivery angle on the conveyor belt, and the soil delivery ang...

Problems solved by technology

This type of conveyor belt forms crests and troughs for a long time, which is prone to stress fatigue and damage, which reduces the soil conveying capacity. It also requires manual work to assist the lateral covering of the film surface, resulting in low
