Needle-type potato seeding device

Abstract

The invention relates to a needle-type potato seeding device which comprises a plurality of needle-type seeders, a chain, a driving shaft, a driven shaft, a furrow opener and a supporting frame. The furrow opener is mounted at the lower end of the supporting frame, the driving shaft and the driven shaft are symmetrically fixed at two ends of the supporting frame, the chain is mounted between the driving shaft and the driven shaft, and the needle-type seeders are equidistantly mounted on the chain. The needle-type potato seeding device has the advantages that the seeding device is simpler in structure, easy to manufacture, convenient to assemble, high in seeding efficiency and long in service life, all sown potato bud seedlings can face upwards, and potato growth is facilitated.

Description

Technical field: [0001] The invention relates to a needle-type potato sowing device, which belongs to the technical field of agricultural machinery. Background technique: [0002] Potatoes have been widely valued by government departments because of their increasingly important role in ensuring food security. In 2010, China released the twelfth five-year plan for the potato industry, which mentioned that by 2015, China's total potato production will reach 150 million tons, the planting area will reach 120 million mu, and the compound annual growth rate will reach 13%. . At present, there are two sowing methods for potatoes. One is to sow potatoes directly without buds after cutting into pieces. This method has realized mechanized sowing; the other is to shave potatoes and accelerate germination, and the sprouts will grow to about 3cm before sprouting. Sowing, this kind of budding requires that the sprouts must face up when sowing. Now sowing is all done manually, with low ...

At present, there are two sowing methods for potatoes. One is to sow potatoes directly without buds after cutting into pieces. This method has realized mechanized sowing; the other is to shave potatoes and accelerate germination, and the sprouts will grow to about 3cm before sprouting. Sowing, this kind of budding requires that the sprouts must face up when sowing. Now sowing is all done manually, with low work efficiency and high labor intensity. The main reason is that the potato planting process is often very troublesome. Using the existing When the potato planter is sowing potatoes, some potato sprouts are facing upwards and some are downwards. It is impossible to ensure that all potato sprouts are facing upwards, which will affect the growth of potatoes.

The utility model with the patent number 2016207650448 relates to a touch bar seeder for potato planters; the utility model with patent number 201620765043.3 relates to a cam-type seeder for potato planters; The seeder of the planter, although the above seeders can make the potato sprouts sown all face up, which is conducive to the growth of potatoes, but these seeders have complicated structures and high manufacturing costs. Therefore, it is necessary to further improve the potato seeder. improvement of
