Squeeze corn thresher based on multi-row roller chain

Abstract

The invention discloses a squeeze-type corn thresher based on multiple rows of roller chains, which belongs to the field of agricultural product production and processing equipment, and includes a frame, a cover plate is arranged on the outside of the frame, and a pulley is arranged on the outside of the cover plate, and the top of the frame and the There are motors on the bottom, and the motors are connected with the pulleys; there are positioning rods on the frame, and the bearing seats are connected to the positioning rods through fasteners, and the bearing seats are provided with bearings; the upper and lower sets of bearings are connected in the frame. The extrusion rubbing mechanism includes a driving shaft and a driven shaft whose two ends are connected to the bearings. The driving shaft and the driven shaft are engaged with multiple rows of roller chains, and the outer surface of the multi-row roller chains is axially There is a wedge-shaped threshing rack, the gap between the rollers forms a sieve hole, and the drive shaft is connected to the pulley through a bearing; the right side of the frame is equipped with a feeding port, the left side is provided with a core discharge port, and the bottom of the extrusion rubbing mechanism is provided. There is a grain outlet, and a feeding baffle is connected below the feeding inlet, and the lower edge of the feeding baffle is located at the upper part of the lower squeezing mechanism.

Description

technical field [0001] The invention belongs to the field of agricultural product production and processing equipment, and in particular relates to a squeezing corn thresher based on a multi-row roller chain. Background technique [0002] At present, corn harvesting in the Huang-Huai-Hai region of my country is still dominated by manual or mechanical ear picking, which requires a lot of labor and production costs. However, the existing corn grain harvester is limited by the moisture content, and the breakage rate during the harvest process cannot be achieved. It reached the national standard, resulting in a large loss of grain. In addition, the corn cob core was severely broken, which increased the impurity content of corn grain. [0003] The traditional corn thresher relies on high-speed agitation and impact to detach corn kernels from the ear to complete the threshing operation, but this threshing method has a big defect: when the moisture content of the ear is lower than 1...

[0002] At present, corn harvesting in the Huang-Huai-Hai region of my country is still dominated by manual or mechanical ear picking, which requires a lot of labor and production costs. However, the existing corn grain harvester is limited by the moisture content, and the breakage rate during the harvest process cannot be achieved. Meet the national standard, resulting in a large loss of grain, in addition, the corn cob core is severely broken, which increases the impurity content of corn grain

[0003] The traditional corn thresher relies on high-speed agitation and impact to detach corn kernels from the ear to complete the threshing operation, but this threshing method has a big defect: when the moisture content of the ear is lower than 15%, it is easy to break the corn kernels; When the moisture content of the ear is 15-19%, it is easy to cause damage to the grain epidermis; when the moisture content of the ear is higher than 19%, the removal rate will decrease, and the damage of individual grain epidermis is serious, resulting in a decrease in the total loss rate
