Seeder feeding device capable of changing number of seeds

Abstract

The invention discloses a seeder feeding device capable of changing the number of seeds, and relates to the technical field of agricultural equipment. The feeding device comprises a positioning frame,wherein a feed port and a discharge port are formed in the top and the bottom of the positioning frame respectively, and are identical in size, and the feed port and the discharge port are distributed symmetrically with reference to the middle point of the positioning frame, namely, the distance between the feed port and the center of the circle of the positioning frame is the same as that between the discharge port and the center of the circle of the positioning frame. According to the seeder feeding device capable of changing the number of seeds, different numbers of pushing blocks are arranged on the surfaces of first, second and third conveying wheels, a baffle is driven by the pushing blocks to move, and the feed number of the device can be adjusted, so that the device is applicableto sowing of different crops, the application range of the device is increased, practicability and applicability of the device are improved, replacement of different blanking baffles or change of thesize of a blanking port is not needed, and accordingly, production efficiency is improved while working time is saved.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a seeder feeding device capable of changing the number of seeds. Background technique [0002] Different crops have different requirements for the number of seeds at one point when sowing. For example, corn generally plants two to three seeds in one point, while garlic only needs to sow one seed at one point. The existing planter When performing sowing operations for different crops, it is often necessary to replace different blanking baffles or change the size of the blanking opening, which consumes a certain amount of working time during the replacement process and reduces production efficiency. At the same time, the number of seeds sown cannot be guaranteed. Stability, if the number of seeds is too much, it will affect the subsequent growth of the plant, reducing the survival rate of seedlings, and if the number of seeds is too small, it will affect the yield of...

[0002] Different crops have different requirements for the number of seeds at one point when sowing. For example, corn generally plants two to three seeds in one point, while garlic only needs to sow one seed at one point. The existing planter When sowing different crops, it is often necessary to replace different blanking baffles or change the size of the blanking opening, which consumes a certain amount of working time during the replacement process and reduces production efficiency. At the same time, it is impossible to guarantee the number of seeds sown Stable, if the number of seeds is too much, it will affect the subsequent growth of the plant, reducing the survival rate of seedlings, and if the number of seeds is too small, it will affect the yield of crops, so it is very important to control the number and stability of seeds when sowing
