Agricultural machinery thresher with protection device

Abstract

The invention discloses an agricultural machinery thresher with a protection device, and relates to the technical field of agricultural machinery. The agricultural machinery thresher with the protection device comprises a threshing cylinder, wherein a motor is arranged in an inner cavity of the threshing cylinder, a motor shaft of the motor penetrates through a rear end surface of the threshing cylinder, matching driven gears are arranged on both the left and right sides of the threshing cylinder, rotating shafts are fixed onto the two sets of driven gears in an embedded mode, the peripheriesof both sets of rotating shafts are sleeved with threshing rollers, a fixing platform is arranged on the top of the threshing cylinder, pushing cylinders are arranged in positions, corresponding to both sets of threshing rollers, on the top of the fixing platform, first through holes are formed in positions, corresponding to the bottoms of both sets of pushing cylinders, of the fixing platform ina through mode, first motor bases are arranged on the tops of both sets of pushing cylinders, first reducers are arranged in inner cavities of both sets of first motor bases, and rotating rods are connected with the bottoms of both sets of first reducers. By means of the device, efficient rice threshing work is achieved, and efficient grain screening work can be conducted during threshing work, sothat plump grains are kept.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a threshing machine for agricultural machinery with a protection device. Background technique [0002] A thresher is a harvesting machine, which refers to a machine that can separate crop grains from stalks, mainly referring to harvesting machines for food crops. According to the different crops, there are different types of threshers. For example, "rice thresher" is suitable for rice threshing; the one used for corn threshing is called "corn thresher" and so on. Rice threshing machine, commonly known as "threshing machine", is the most common rice threshing machine. [0003] After the rice is mature, it is necessary to perform threshing operations on the grains on the rice, so as to realize the collection of rice grains. Most of the current threshing machines need manual threshing operations, which not only increases the labor of the staff. Labor intensity redu...

Problems solved by technology

[0003] After the rice is mature, it is necessary to perform threshing operations on the grains on the rice, so as to realize the collection of rice grains. Most of the current threshing machines need manual threshing operations, which not only increases the labor of the staff. Labor intensity reduces threshing efficiency, time-consuming and labor-intensive, and when the rice is manually fed into the threshing machine, the operator's hands are easily involved in the threshing machine, which in turn causes injury to the operator and makes the threshing machine The safety of the grain machine is reduced. At the same time, the existing threshing machine cannot effectively screen the grains and husks in the rice grains, and keep the grains with full grains. Therefore, a kind of threshing machine with a protective device Threshing machines for agricultural machinery are of great practical value
