Impact casting device for casting soil to on-film holes

Abstract

An impact casting device for casting soil to on-film holes comprises a soil tank, an impact casting device body, a soil auger and an impact casting device switch, wherein the soil tank comprises a preserved opening and a lower channel; the impact casting device body comprises an impact casting engine, an impact casting engine connector, a sealing cover, an impact casting piston, a soil discharge outlet, a guiding device, a leakage preventer switch, a leakage preventer, a soil inlet, a soil casting hole, a closing spring and a mounting seat; the impact casting device switch comprises an actuator and a driven device. The impact casting device is mainly characterized in that the intermittent type sawtoothed soil auger is used in the soil tank, the impact casting device body is arranged insidethe soil tank, the impact casting engine is arranged on the upper portion of the impact casting device body, the leakage preventer and the leakage preventer switch are arranged on the lower portion of the impact casting device body, and the actuator and the driven device of the impact casting device switch are arranged outside the soil tank. Due to the fact that the impact casting device is usedfor casting soil to the on-film holes, precise soil casting is achieved, soil covering the seed holes is in good contact with seeds in a seamless manner, and the survival rate of the germinated seedsis guaranteed.

Description

technical field [0001] The invention relates to a device for throwing soil into a seed hole on a film. Background technique [0002] At present, there are two main ways to throw soil into the seed hole on the film: manual and mechanical. Manually throw wet sand or dry sand to the seed hole in the form of walking upright. The seed coverage is solid, but the labor intensity is high and the efficiency is low; mechanical Various devices are used to make wet sand or dry sand fall into the seed hole naturally. The amount of dry sand is large, and the wet sand seeds are covered with gaps, and the walking inertia of the machine will greatly affect the covering quality of the seed hole. Contents of the invention [0003] The purpose of the present invention is to provide a kind of seed hole soil throwing device which can realize accurate soil throwing, avoid the gaps covered by seeds, overcome the influence of inertia, and save sand and high efficiency. [0004] Technical solution...
