Conveying chute and harvester

Abstract

The invention discloses a conveying chute which comprises a guide chute. Driving rollers are arranged at the front end of the guide chute, driven rollers are arranged at the rear end of the guide chute, and first chain harrows, second chain harrows and third chain harrows are in parallel arrangement at intervals, externally wound on the driving rollers and the driven rollers and used for materialharrowing transmission. The first chain harrows are positioned on the left side of an inner cavity of the guide chute, the second chain harrows are positioned in the middle of the inner cavity of theguide chute, and the third chain harrows are positioned on the right side of the inner cavity of the guide chute. The first chain harrows, the second chain harrows and the third chain harrows are identical in motion direction but different in motion speed. The invention further discloses the harvester. Efficient conveying and feeding of crops such as rice, oilseed rape and the like can be realized, and unnecessary loss is effectively avoided; efficient conveying and feeding of crops such as rice, corns, sorghum and the like can be realized, and normal operating of equipment is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of agricultural machinery, and more specifically, relates to a conveying trough and a harvester. Background technique [0002] Rice belongs to the Poaceae Oryza genus and is an extremely ancient crop. According to archaeological findings, rice has been planted in my country for at least 7,000 years. There are two kinds of cultivated rice in the world, that is, Asian cultivated rice and African cultivated rice. Among them, Asian cultivated rice has a large planting area and spreads all over the rice regions all over the world. It is called common cultivated rice. The rice panicle is composed of many spikelets, and the seed of rice is paddy rice, which is called rice or rice after shelling. In addition to being edible, rice can also be used to make wine and be used as the main raw material for sugar production. Rice husk and rice straw also have many uses. At present, China's annual grain output has reached 500 milli...

Problems solved by technology

In actual operation, in order to save production costs, farmers often use harvesters to harvest corn, sorghum, wheat, soybeans and other crops at the same time to achieve a multi-purpose machine. However, because conventional harvesters are generally designed to match rice, rice and corn, sorghum, Wheat, soybeans and other crops have different characteristics such as degree of entanglement, stalk flexibility and hardness, and stalk size. Therefore, the conveying trough of a conventional harvester is prone to blockage when transporting other stalks, resulting in unsmooth feeding of the threshing chamber. Seriously affect the normal operation of the equipment
