Half-feeding combine harvester

Abstract

The invention belongs to the technical field of harvesters, and relates to a half-feeding combine harvester. The half-feeding combine harvester comprises a walking mechanism, a grain unloading mechanism, a threshing mechanism arranged on one side of the grain unloading mechanism and a crop cutting and conveying mechanism arranged on one side of the threshing mechanism; the threshing mechanism comprises a shell, two rotating rollers erected in the shell and a threshing conveying belt installed on the two rotating rollers; a first cover plate for preventing grains from splashing out is arranged on the shell; a feeding port is formed in one end of the first cover plate and the shell, and a discharging port is formed in the other end of the first cover plate and the shell; a plurality of first threshing parts located on one side, a plurality of second threshing parts located in the middle and a plurality of third threshing parts located on the other side are formed on the threshing conveying belt; blocking plates used for preventing grains from falling off are arranged on the outer sides of the first threshing parts and the outer sides of the third threshing parts; and threshing rods are arranged on the first threshing parts, the second threshing parts and the third threshing parts correspondingly. The invention aims to provide the half-feeding combine harvester which is stable in structure, high in protection performance and high in safety performance.

Description

technical field [0001] The invention belongs to the technical field of harvesters, in particular to a half-feed combine harvester. Background technique [0002] Existing half-feed combine harvesters mainly contain two kinds of full-feed and half-feed. One: In the process of the above two types of harvesters from cutting, conveying, threshing, to the final grass discharge process, etc., the path of the two harvesters is relatively long, and the crops and straws are all in a messy state of lodging and shaking, which is very easy to cause The falling of mature grains leads to loss and great food waste, and the machine has a large volume and complex structure. Second: The grain threshing devices of the above two harvesters use the high-speed rotating bow-shaped toothed drum and the concave plate screen to complete the threshing, resulting in the splashing loss of the grain falling down, causing too many rice leaves and thin rods to fall from the The stalks are scraped off and ...

Problems solved by technology

One: In the process of the above two types of harvesters from cutting, conveying, threshing, to the final grass discharge process, etc., the path of the two harvesters is relatively long, and the crops and straws are all in a messy state of lodging and shaking, which is very easy to cause Mature grains fall and cause great food waste, and the machine is large in size and complex in structure

Second: The grain threshing devices of the above two harvesters use the high-speed rotating bow-shaped toothed drum and the concave plate screen to complete the threshing, resulting in the splashing loss of the grain falling down, causing too many rice leaves and thin rods to fall from the The stalks are scraped off and mixed with the grains, which increases the complexity of the cleaning process and entrains a lot of grains in the final grass discharge process. High rate, not conducive to economic benefits
