Grain thresher

Abstract

The invention discloses a grain thresher. The grain thresher structurally includes a rolling cylinder, a protective cover, a peeling feeding port, a separation chamber, a threshing feeding port, a rack, an air blower, a belt pulley, a time controller, a power line, a steering handle, a material discharging port, a cutter disc, a cutter, a bidirectional switch and a motor; the rolling cylinder is connected with the protective cover, the time controller is composed of a spring, a locking chain, a lapping hook, a lever, armature iron, an undervoltage unbuckling device, a double metal sheet, a resistor and an over-current unbuckling device, and the spring is connected with the locking chain; the locking chain is connected with the lever through the lapping hook, and the bidirectional switch isconnected with the motor. Through arrangement of the time controller, the thresher can automatically stop running for a rest after running for a fixed time, and operators can be reminded to carry outsafety examination on a power machine of the thresher; in this way, operators can have a rest, the machinery can be maintained, and the accident rate is reduced.

Description

technical field [0001] The invention is a grain thresher and belongs to the field of threshers. 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. After the rice is harvested first, the rice grains are separated from the stalks by this machine. Rice threshers are divided into two categories, one is driven by manpower, which is 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 emergence of the rice thresher has greatly reduced t...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a grain thresher to solve the problem that when the existing grain thresher harvests and threshes, it often needs to work continuously day and night, which makes it easy for the machine to be unmaintained and the power machine to be safe. inspection, accident-prone problems
