An embedded mulch bedding drilling and seeding machine

Abstract

The invention relates to an embedded mulch covering perforating seeder, which is suitable for field film spreading and sowing, and belongs to the field of agricultural machinery. It consists of drive assembly, transmission system, drive wheel, mulch, opener, pressure wheel, electric push rod, spraying system, control box, embedded film disc, spring, duckbill perforated sowing roller, fertilizer box, row The device is composed of a seeder, a fertilizer applicator and a frame. The device is driven by the drive assembly through the drive system to drive the drive wheel to work. The opener column is installed on the adjustable frame, and the opener and the opener column are installed at 45°. On the column of the opener, two film-embedded discs at a 45° angle to the column cooperate with the opener to complete the film laying. Duckbill punching sowing rollers are installed at the rear end of the rack, and the distance between each duckbill is adjustable. A truncated conical pressing wheel is installed at the rear end of the whole machine, and the pressure can be adjusted by the monitoring system according to agricultural requirements. Duckbill perforated sowing roller, fertilizer box, seed meter and fertilizer applicator constitute the sowing system of the device. The device is designed with two sets of sowing systems, which are installed equidistantly on both sides of the frame to complete the fertilization and sowing process. The control box controls the lamination strength of the device by controlling the expansion and contraction of the electric push rod.

Description

technical field [0001] The invention relates to an embedded mulching and perforating seeder, which belongs to the field of agricultural machinery. The main innovation points are the ditching and film covering method and the perforating and sowing device. Background technique [0002] KDF-1, 2BFM-2 and other traditional plastic film covering machines, after ditching, laying film, and then covering with soil and suppressing. This type of traditional laminating machine requires a large trenching depth and a large laminating area to ensure the stability of the film, so the utilization rate of the film is not high and the energy consumption is large. The tractor does not run straight, and the distance between the covering devices is unreasonable, which leads to the inappropriate amount of covering soil and the deflection and curling of the mulch film. The seedling picking process in the later stage will damage the seedlings, and the size of the punched holes cannot be controlled...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the invention is to provide a new type of plastic film covering perforating seeder in order to overcome the disadvantages of the existing plastic film machine, such as poor film fixing effect, excessive soil covering area, bulky body structure, and different sizes of punching holes in the later stage.

[0004] In order to solve the problems of poor fixation effect of the plastic film and excessive soil covering area of ​​the plastic film, the technical solution adopted is: to improve the traditional trenching and film covering method, the front-end opener is used to open the trench, and the rear end uses a film-embedded disc to cover the plastic film. The method of embedding in the soil at 45° to the ground is mainly to embed a small amount of mulch into the soil obliquely to improve the utilization rate of the mulch
