Disc-like turntable type scriber for mulching crops on ridges

Abstract

The invention relates to a disc-like turntable type scriber for mulching crops on ridges. The scriber comprises a cross shaft (1), disc-like turntables (2), a push rod (3), positioning holes (4) and positioning pins (5). The scriber is characterized in that the three disc-like turntables (2) are respectively arranged on the middle part and two sides of the cross shaft (1), the disc-like turntables (2) can rotate around the cross shaft (1), two sides of each disc-like turntable (2) are provided with positioning holes (4), the positioning pins (5) are arranged in the positioning holes (4), and the push rod (3) is arranged vertically on the middle part of the cross shaft (1). When the scriber is in use, the push rod is pushed forwards, and the three disc-like turntables rotate into soil at a certain depth and leave travel trajectories of a certain depth on soil, wherein the travel trajectories serve as reference lines for mulching the crops in the later period to ensure that the mulch films are equal in distance, straight and uniform and facilitate the subsequent mechanized farming.

Description

technical field [0001] The invention relates to an agricultural machine tool, in particular to a dish-shaped turntable type film-coated liner for ridge-sowed crops. Background technique [0002] With the development of plastic film mulching planting, when some ridge-sown crops are covered with film, there is one line of film surface and one line of empty ridge. According to the width of the film surface and the width of the ridge, first draw a straight reference line on the ground. The traditional line drawing device is to fix 2-3 wooden stakes on a horizontal bar, and set a fixed wooden stake in the middle of the horizontal bar. When drawing the line, pull the lever with both hands and turn your back forward. The operator walks backwards. The 2-3 wooden stakes of the line drawing device will leave clear scratches on the ground, which will be used as a reference line for the next step of laminating. Its disadvantages are: (1) When drawing a line, the operator backs to the f...

AI Technical Summary

Problems solved by technology

The disadvantages are: (1) When drawing the line, the operator is walking with his back to the front and pulling the line drawing device backwards. Since he cannot see the road ahead when walking, the speed is very slow and the efficiency is very low

(2) When drawing a line, the operator turns his back to the front and pulls the line drawing device backwards to walk. Since the error of the previously drawn reference line cannot be seen when walking, the error of the previous line drawing cannot be used. Correct the next drawing line at any time, so that the drawing line continues to bend, so that the film surface of the film is bent, and the row spacing is not equal, which will easily cause the error of the sowing position in the later stage, and also increase the difficulty and accuracy of the mechanized operation in the later stage
