Straw crushing and throwing method and device of full-feeding combine harvester

Abstract

The invention discloses a straw crushing and throwing method and a device of a full-feeding combine harvester. The method adopts a coaxial different-speed transmission mode, uses a low-speed shaft todrive the threshing teeth to do threshing, and uses a high-speed shaft to drive the crushing teeth and a crushing cutter which corresponds to the crushing teeth to crush the straw. The device is characterized in that a crushing auxiliary board (13) is connected on a solid shaft (1); a crushing teeth rod (14) is installed on the crushing auxiliary board (13); crushing teeth (15) are arranged on thecrushing teeth rod (14); a hollow shaft (3) is sheathed outside the solid shaft (1); a threshing auxiliary board (10) is connected on the hollow shaft (3); threshing teeth rod (11) is installed on the threshing auxiliary board (10); and the threshing teeth (12) are arranged on the threshing teeth rod (11). The straw crushing and throwing method and the device of the full-feeding combine harvestercan crush the straw and then evenly throw the straw into the earth when in harvest, can reduce the spray speed of the crushed straw so as to avoid the crushed straw from injuring people, thus improving the security.

Description

technical field [0001] The invention relates to a harvesting machine, in particular to a straw crushing and throwing method and device for a full-feed combine harvester. Background technique [0002] The stalk left in the field after the crops are harvested is usually burned into ashes, and then the stalk ash is mixed into the soil when the ground is turned, as a fertilizer. During the harvest season, when many farmers burn straw, the smoke fills the air, covering the earth, just like casting a thick layer of fog on the earth. polluted the air quality. Especially in the farmland near the airport, when burning stalks, the smog of burning shrouds the ground, making the pilot unable to see the runway, which has a strong impact on the landing safety of the aircraft. So the country issued a notice recently to prohibit burning stalks in the field, and this has just proposed new requirements to the processing of stalks after harvesting. As a manufacturer of agricultural harvesti...

Problems solved by technology

Due to the limitation of the installation position and space, the size of this external-mounted pulverizer cannot be made very large, so the diameter of the rotating part of the pulverizer is relatively small. In order to increase the linear speed to achieve the purpose of pulverization, it is required to increase the speed. Therefore, the current external-mounted pulverizer consumes a lot of energy and noise.

In addition, due to the relatively high installation position of the pulverizer, at the exit of the pulverizer, the short straw after being pulverized is ejected from the pulverizer outlet like a bullet. If it is hit on a person, it is very unsafe. Or other vital parts that may cause personal injury
