Forced feeding, threshing, separating and smashing integrated device for first-harvest rice

Abstract

The invention provides a forced feeding, threshing, separating and smashing integrated device for first-harvest rice. The forced feeding, threshing, separating and smashing integrated device for first-harvest rice comprises a closed multifunctional threshing cylinder, a flow guide separable grass breaking top cover and a combined concave plate, wherein the threshing cylinder comprises a cylinder shaft feeding head and a cylinder body, a spiral blade is mounted on the feeding head, and an arc tooth group, a spike tooth group and a roller rotating blade group are distributed on the circumferenceof the cylinder body sequentially; the combined concave plate is located below the closed multifunctional threshing cylinder and comprises a transition concave plate, a threshing concave plate, a separating concave plate and a grass guiding concave plate sequentially; the flow guide separable grass breaking top cover is mounted above the closed multifunctional threshing cylinder and comprises a top cover inner shell and reinforcing plates, and the top cover inner shell comprises an adjusting mechanism, flow guide bars, punching plates and top cover fixed blades. The forced feeding, threshing,separating and smashing integrated device is applicable to feeding, threshing, separating and smashing of the first-harvest rice with different characteristics, has the advantages of compact structure, large separation area, light weight and the like, can effectively improve threshing performance and efficiency of the first-harvest rice and has lower power consumption.

Description

technical field [0001] The invention relates to the technical field of combine harvesters, in particular to an integrated device for force-feeding first crop rice for threshing, separating and pulverizing. Background technique [0002] Raising rice is planted once and harvested twice, that is, after the first season of rice is harvested, only the upper two-thirds of the rice plant is cut off, and the ears of rice are harvested, leaving the lower one-third of the plant and root system for fertilization and cultivation. , let it grow another season of rice, and then harvest the second season. It has many advantages such as labor saving, plant saving, water saving, fertilizer saving, drug saving, and seedling saving. Improving the mechanical harvesting ability of the first crop of ratooning rice is an important measure to reduce labor force and increase the yield of ratooning rice, which is of great significance to the development of ratooning rice in my country. [0003] The...
