Straw provocation device after tractor tire compacts straw

Abstract

The invention relates to a straw stirring device after the straw is compacted by tractor tires, which is arranged between the rear wheels of the tractor and the straw returning machine, and a plurality of straw picking devices are installed on the straw returning machine casing corresponding to the tractor ruts on the front end face of the stalk; the straw provocative device includes a fixed square steel, a "U"-shaped card, a fixed plate, a spring threaded pressure rod, a threaded disc, a support plate, a rotating pin, a toggle plate, a spring pressing block, a spring and a threaded Briquetting. The present invention has a variety of ways to adjust the inclination of the toggle plate, and the operation is simple and convenient; when returning to the field, when the straw provocation device encounters a hard stone, the spring can be compressed to ensure the smooth passage of the toggle plate; When the time is up, the spring resets the toggle plate, which can effectively ensure the operation effect and life of the straw stirring device; the angle between the two toggle plates can be adjusted according to the field operation environment to improve the quality of the straw stirring operation.

Description

technical field [0001] The invention relates to a straw provocation device after the straw is compacted by tractor tires, and belongs to the technical field of agricultural machinery. Background technique [0002] When the straw is crushed and returned to the field, the straw crushed and returned machine is attached to the rear of the tractor, and the tractor tires will compact the straw on the ground surface, so that the straw crushed and returned machine cannot effectively pick up the straw compacted by the tractor tires, thus The straw picking rate is reduced, which in turn reduces the quality of straw crushing. The usual countermeasure is to use a longer pulverizer at the tractor tire pinch. However, when the straw is returned to the field, the use of a long pulverizer cannot be adjusted according to the field operating conditions; the long pulverizer rotates at high speed and easily hits hard stones in the field, which is prone to safety accidents and endangers the saf...

Problems solved by technology

However, when the straw is returned to the field, the use of a long pulverizer cannot be adjusted according to the field operation conditions; the long pulverizer rotates at high speed and easily hits hard stones in the field, which is prone to safety accidents and endangers the safety of the machine operator; The working environment is complicated, and the working radius of the long pulverizer cannot be accurately determined, which leads to the fact that the long pulverizer is easy to cut the soil during operation, thereby increasing the vibration of the machine tool and operating energy consumption, reducing the working quality and service life of the machine tool
