AI Technical Summary
The existing agricultural production threshers often contain broken corn core rods after threshing, resulting in the threshing corn kernels containing more impurities, which affects subsequent operations.
An agricultural production threshing equipment is designed. The first motor drives the first pulley and the threshing rod to rotate the corn, and then the corn slides out of the grain slide plate and falls on the screening plate. The second motor starts to drive the connecting rod, connecting column, moving rod and half gear to swing back and forth, so that the screening plate drives the slider to slide back and forth in the slide chute, thereby screening the threshing corn and removing the crushed corn cob.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural production equipment, in particular to agricultural production threshing equipment. Background Art
[0002] Agriculture refers to the production method in which humans use land to grow crops, raise animals and carry out related agricultural activities. Agriculture is one of the earliest economic activities of mankind and one of the important industries in modern society. Through agriculture, people can obtain food, fiber, energy and other necessities of life. At the same time, agriculture also provides employment opportunities and plays an important role in economic development and food safety. In agricultural development, science and technology and innovation also play an important role, such as the application of agricultural mechanization, greenhouse cultivation, precision agriculture and other technologies. In agriculture, corn is also known as corn, pearl grain, etc. It is a plant of the genus Zea mays in the Poaceae family. It is native to Central and South America and is now cultivated all over the world. It is an important food crop and feed crop, and also the crop with the highest total output in the world. Because it is rich in various nutrients such as protein, it is known as longevity food and is also an important industrial raw material. After the corn is mature and dried, it needs to be threshed, which requires the use of agricultural production threshing equipment.
[0003] The agricultural production thresher is a device used to thresh the dried corn ears. It is mainly composed of a drum, a concave plate, a sieve, a fan, a feeding hopper, a grain slide plate, a spiral guide rod, etc. Its working principle is: the corn ears enter the drum through the feeding hopper and are threshed under the impact of the high-speed rotating drum and the interaction between the corn ears, the drum and the concave plate. Most of the threshed grains and fine impurities pass through the concave plate holes and are cleaned by the fan. Light impurities are blown out from the impurity discharge port, and the grains slide out of the machine through the grain slide plate. The cob moves backward along the axial direction of the drum and is discharged from the outlet at the end of the shaft through the surface of the vibrating screen. Some of the grains entrained in the cob leak through the sieve holes and enter the grain slide plate to slide out of the machine.
[0004] However, when the existing agricultural production thresher threshes corn, broken corn cobs are often mixed in the threshed corn kernels, and further screening is required after the threshing is completed, so that the threshed kernels contain more impurities, which affects the next step of corn operation. Therefore, an agricultural production threshing equipment is proposed to address the above problem. Utility Model Content
