Telescopic gear type residual film picking and recycling machine

Abstract

The invention discloses a traction frame capable of preventing over-depth plowing of a pull type agricultural machine and an application of the traction frame. The traction frame comprises a triangular frame body, wherein a rotating shaft is connected to the center of a crossbeam at the bottom of the triangular frame body, and a vertical connecting rotating shaft is fixed at the rear end of the rotating shaft and is hinged with a stander of a traction agricultural machine; and a pin shaft is arranged on the top of the triangular frame body and is sleeved by a pull rod fine-adjusting plate, a long round hole is formed in the pull rod fine-adjusting plate, and the pull rod fine-adjusting plate can move relative to the pin shaft. A stretchable rotary-tooth type residual film pickup recovery machine utilizing the traction frame comprises a stander, a driving mechanism, an earthing sharp shovel, a film loosening shovel, a filtered soil conveying grid, a roller stretching type rotary-tooth mechanism, a film stirring mechanism and a film collecting box. The traction frame has the beneficial effects that machines and tools can be flexibly dragged in three-dimensional directions, and the pull rod fine-adjusting plate is capable of easily slightly adjusting the earthing depths of the machines and the tools. The residual film pickup recovery machine utilizing the traction frame is good in residual film pickup effect, high in pickup efficiency, safe, reliable, efficient and labor-saving and can stably work.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a three-point suspension traction frame. Background technique [0002] The tractor is attached to the agricultural machinery, and the three-point suspension is commonly used. This mechanism has good versatility and is suitable for most trailer-mounted agricultural machinery. In the past, agricultural machinery, such as plows, rakes, and seeders, were light in weight, and the three suspension points were fastened with pins or bolts. Mechanical or hydraulic mechanisms can be used to control the depth of shovels and plows in the ground. With more and more types of agricultural machinery and more integrated functions, the weight of agricultural machinery is heavier. Relying on the original hydraulic pressure and other devices of the tractor, the rear-mounted agricultural machinery cannot be lifted directly, and the transformation cost is high. Large, it is difficult to lift direct...

AI Technical Summary

Problems solved by technology

With more and more types of agricultural machinery and more integrated functions, the weight of agricultural machinery is heavier. Relying on the original hydraulic pressure and other devices of the tractor, the rear-mounted agricultural machinery cannot be lifted directly, and the transformation cost is high. Large, it is difficult to lift directly by a tractor, agricultural machinery plus ground wheels can solve this problem

Agricultural machinery with plows, shovels and other parts at the front needs to dig into the soil, such as potato diggers, mulch pickers, etc., which can be moved easily with the ground wheels, but the depth of plows and shovels moving forward with the tractor during operation It is getting bigger and bigger, and the resistance of the tractor is getting bigger. At the end, the exhaust pipe is bursting with smoke, and it is difficult to move forward.
