Film mulching and opening mechanism of full-automatic peanut sowing and film mulching all-in-one machine

Abstract

The invention provides a film mulching and opening mechanism of a full-automatic peanut sowing and film mulching all-in-one machine. The mechanism comprises an opening assembly and a sowing assembly,the opening assembly comprises a turntable, opening pipes and opening teeth, a plurality of seed guide cavities are circumferentially formed in the surface of one side of the turntable, the pluralityof opening pipes are circumferentially and fixedly connected to the side wall of the turntable, and the opening teeth are fixedly connected to one ends of outlets of the opening pipes. The sowing assembly comprises seed guide pipes, limiting blocks, a compression spring, a cam and a positioning shaft, the other end of the positioning shaft is slidably connected to the center of the turntable, thecam is fixedly connected to the other end of the positioning shaft, one ends of the seed guide pipes are slidably connected into the opening pipes, and the limiting blocks are fixedly connected to theother ends of the seed guide pipes; inlets are formed in the side surfaces of the limiting blocks and are flush with cavity openings at one ends of the seed guide cavities; and the turntable is arranged to rotate to enable the seed guide pipes to be regularly pushed by the cam and slide in the opening pipes, so that a material conveying pipe, the seed guide pipes and the opening pipes are communicated with one another at a certain frequency, and the opening and sowing positions and the operation frequency are always kept consistent.

Description

technical field [0001] The invention relates to the technical field of film-covered perforation, in particular to a film-covered hole-perforating mechanism of a fully automatic peanut sowing film-covering machine. Background technique [0002] At present, the automated peanut sowing and film-covering integrated equipment has been widely used by farmers due to its advantages of high production efficiency and low labor intensity of operators. With the development of science and technology, the existing sowing machinery has more comprehensive functions, and has been able to complete various processes such as loosening soil, ditching and fertilizing, ridging, sowing, film covering, spraying pesticides, drilling holes and covering soil at one time. [0003] However, in the actual production process, there are more or less certain defects in various peanut sowing machines. Among them, during the film covering process, it is generally necessary to punch holes in the film covering ...

AI Technical Summary

Problems solved by technology

However, since the sowing device and the film-covered perforating device in the existing equipment are two independent devices, it is difficult to ensure that the perforating position and the sowing position are accurately coincident

[0004] Although technical personnel have made various improvements to this problem, such as coordinating the operating frequency of the seeding device and the film-coated perforating device through the transmission mechanism to keep the same, the effect is not ideal due to the complex and changeable operating terrain; Pore ​​diameter, but too large opening will affect the application effect of the coating
