Grain threshing machine

Abstract

The invention discloses a grain threshing machine. The threshing machine comprises a pedestal, an object taking port, a vibrator, a sharp tooth and a chassis. A separation plate is arranged in the chassis above a storage cavity. The surface of the separation plate is provided with screening holes with an equal interval. The center position of the top end of the separation plate is provided with the vibrator. A filtrating screen is arranged in the chassis above the vibrator. The center position in a threshing cavity is provided with a roller. The center position of the outer side wall of the roller is provided with a connection rod. The center position of the top end of a support is provided with a motor. The two ends of the pedestal top of one side of the chassis are provided with lower push rods. The tops of the lower push rods are hinged to upper push rods. The chassis top end of one side of a feed port is provided with an alarm. A chassis surface at a threshing cavity position is provided with a transparent observation window. In the invention, a threshing effect when the threshing machine is used is increased, the functionality during the usage of the threshing machine is improved, and grain fragmentation during the usage of the threshing machine is avoided.

Description

technical field [0001] The invention relates to the technical field of threshers, in particular to a grain thresher. Background technique [0002] A thresher is a harvesting machine, which refers to a machine that can separate crop grains from stalks. It mainly refers to harvesting machinery for food crops. According to different crops, there are different types of threshers. For example, "rice thresher" is suitable for rice threshing; Corn thresher is called "corn thresher" and so on. Rice thresher is commonly known as "threshing machine". It is the most common rice thresher machine. , rice threshers are divided into two categories, one is driven by manpower, called "manpower rice thresher", which is a semi-mechanized tool; if the rice thresher is changed to power drive, it is called "power rice thresher".

[0002] A thresher is a harvesting machine, which refers to a machine that can separate crop grains from stalks. It mainly refers to harvesting machinery for food crops. According to different crops, there are different types of threshers. For example, "rice thresher" is suitable for rice threshing; Corn thresher is called "corn thresher" and so on. Rice thresher is commonly known as "threshing machine". It is the most common rice thresher machine. , rice threshers are divided into two categories, one is driven by manpower, called "manpower rice thresher", which is a semi-mechanized tool; if the rice thresher is changed to power drive, it is called "power rice thresher". The appearance of rice harvesting machine has greatly reduced the labor intensity of rice harvesting, and also improved agricultural productivity. Traditional threshers are various, and their functions are relatively single, which can only meet people's simple needs. During the threshing process, threshers cannot Completely separated, the threshing effect is limited. In the process of grain transportation, it is generally necessary to thresh the grain now and then transport it to a designated point. If the threshing machine has the corresponding transportation function, the functionality of the threshing machine is bound to be improved. Generally, the effect needs to be controlled. If the effect is too large, it will cause the grain to break. If the thresher has the corresponding monitoring function, it can avoid the damage of the grain during threshing.
