Hole sowing machine

Abstract

The invention relates to a hole sowing machine. A plurality of seed storage hoppers are uniformly arrayed and supported in a frame, the upper end of the frame is connected with a crankshaft, one end of the crankshaft is connected with a power input shaft, the two ends of the crankshaft are movably hinged with two vertical connecting rods respectively, and the lower ends of the two vertical connecting rods are connected with a lifting beam; and a protection pipe penetrates through the plurality of seed storage hoppers respectively, a seed inlet corresponding to the bottom of each seed storage hopper is formed on each protection pipe, a lifting groove is reserved on the protection pipe below the seed inlet along the direction of the protection pipe, a seed delivery pipe is arranged in each protection pipe, a first sowing opening, a lifting pin hole and a second sowing opening are formed on the seed delivery pipe from the top to the bottom in turn, the first sowing opening of the seed delivery pipe corresponds to the seed inlet of the protection pipe, the seed delivery pipe penetrates through the lifting pin hole through a lifting pin, the lifting groove of the protection pipe is fixedly connected with the lifting beam, and the second sowing opening is formed at the bottom of the seed delivery pipe and retracts in or extends out of the protection pipe to realize the separated and uniform falling of seeds in each seed storage hopper. The hole sowing machine has a simple and compact structure, is convenient to operate, low in labor intensity and suitable to be used in small-area farmlands.

Description

technical field [0001] The invention relates to a hole sowing machine, in particular to a hole sowing machine for direct seeding rice. Background technique [0002] In the 1950s, live broadcasting of rice was promoted on a large scale in northern my country. Before the 1980s, direct seeding of rice in Heilongjiang Province accounted for 70%, and in southern China, live broadcasting was also used in the 1960s. In recent years, with the development of the economy, a large number of young and middle-aged laborers in rural areas have entered the urban labor market, the reduction of rural labor force, and the widespread use of chemical herbicides, direct seeding rice cultivation has shown a trend of rapid development. Compared with the traditional rice planting method, this technology saves the steps of rice seedling raising and planting, and the rice seeds are directly sown with a drill after soaking and germination, which has the advantages of labor saving, cost saving, and eff...

AI Technical Summary

Problems solved by technology

At present, there are many rice direct seeding machines on the market. Most of the rice direct seeding machines are large-scale machines used for large-scale sowing. Their structures are complex, large in size, heavy in weight, and inconvenient to transport, so they cannot be used in small-area farmland in rural my country
