Straw poking device after compacting straws by tractor tire

Abstract

The invention relates to a straw poking device after compacting straws by a tractor tire. The straw poking device is arranged between a rear wheel of a tractor and a straw returning machine, and a plurality of straw poking devices and tractor tracks are correspondingly arranged on the front end surface of a returning machine shell of the straw returning machine; each straw poking device comprisesfixed square steel, a U-shaped clamp, a fixed plate, a spring threaded pressing rod, a threaded disc, a supporting plate, a rotating pin, a poking plate, a spring pressing block, a spring and a threaded pressing block. The device has multiple modes for adjusting an inclination angle of the poking plate, and is simple and convenient to operate; during returning operation, when the straw poking device encounters hard stones, the poking plate can pass through smoothly by compressing the spring; when the straw poking device leaves the hard stone, the poking plate is reset by the spring, so that the operation effect and the service life of the straw poking device can be effectively ensured; and the included angle between the two poking plates can be adjusted according to the field operation environment, so that the straw poking operation quality is improved.

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
