Press-bar-type seeder for potato planter

Abstract

The invention relates to a pressure-bar type seeder for a potato seeder, comprising a support box, a vertical pressure rod, a shaft sleeve, a left connecting rod, a right connecting rod, a left sliding plate, a right sliding plate, a guide shaft and a sliding plate frame. The front and rear sides are symmetrically welded with two front and rear skateboard frames. The support box is located in the middle of the front and rear skateboard frames. The left and right slide plates are symmetrically arranged between the front and rear two skateboard frames. The vertical pressure rod is fixed to the support box through the shaft sleeve. On the front side of the vertical pressure rod, the lower end of the vertical pressure rod is hinged with the upper end of the left link and the right link through the shaft pin. The left skateboard and the right skateboard slide left and right. The beneficial effects of the invention are that the structure is reasonable, the manufacture is easy, the installation is convenient, the service life is long, and the material is automatically unloaded, so that all the sown potato sprouts can face upwards, which is beneficial to the growth of potatoes.

Description

Technical field: [0001] The invention relates to a pressing rod type seeder of a potato planter, 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 sprouts after cutting into pieces. This method has realized mechanized sowing; the other is to accelerate germination after cutting potatoes, and the sprouts grow to about 1-3cm. Sowing with buds, this kind of buds requires that the sprouts must face up when sowing. Now sowing is done manually, the wor...

Problems solved by technology

At present, there are two sowing methods for potatoes. One is to sow potatoes directly without sprouts after cutting into pieces. This method has realized mechanized sowing; the other is to accelerate germination after cutting potatoes, and the sprouts grow to about 1-3cm. Sowing with buds, this kind of buds requires that the sprouts must face up when sowing. Now sowing is done manually, the work efficiency is low, and the labor intensity is high. The main reason is that the potato planting process is often very troublesome. When some potato planters sow potatoes, some potato buds face up and some face down. It is impossible to ensure that all the potato buds face up, which will affect the growth of potatoes.
