Description

A triple-pressure seeder for peanut cultivation

Technical field

The invention relates to the technical field of crushing seeders, and in particular to a triple crushing seeder for peanut planting.

Background technique

"Complete seedlings, neat seedlings, uniform seedlings, and strong seedlings" are the prerequisites for high peanut yields. Currently, it is advocated to return straw to the field, which leads to loose soil or large pieces of straw fiber in the field, which brings the following problems to sowing peanuts. :

1. When sowing peanuts in loose sandy soil or wheat stubble fields where straw has been returned to the field, the soil is too loose and it is difficult to raise ridges, which affects the growth of peanuts;

2. Due to soil quality or straw return, some land has large soil clods or large pieces of straw fiber, causing the bottom of the sowing trench cut by the seeder to be uneven. After the peanut seeds fall into the soil, due to the uneven sowing position of the soil, the sprouting end of the peanut seeds sometimes faces downwards. After sprouting, they need to bend upward first before growing upward, and then drill out of the ground. Due to the limited nutrients in the peanut seeds, weak seedlings appear. ; 3. Because the soil is relatively loose, the contact between the soil and the seeds is not close, causing the seeds to dry out.

Uniform spreading and the combination of the two fertilization methods are conducive to increasing soil fertility, and this fertilization method is located in front of the sowing method. The two are synchronized, which is conducive to improving the efficiency of the entire peanut sowing. Under the action of the plate and the fertilizer discharge adjustment mechanism, in order to realize the up and down swing of the screen and the intermittent opening and closing of the baffle, on the one hand, it accelerates the uniform fall of calcium fertilizer and organic fertilizer in the first fertilizer box, and the setting of the screen, In order to make the fertilizer particles finer for easier absorption by the soil, on the other hand, it realizes the intermittent falling of the compound fertilizer to achieve even application of the compound fertilizer, thereby further improving the uniformity of fertilizer application and conducive to improving the quality of peanuts. subsequent nutrient uptake by seeds;

Under the action of the drum-type soil covering roller, through holes and spiral blades, the film on the film spreading roller can be evenly covered with soil in a full layer, and through the action of the lifting adjustment mechanism, the leveling pressure roller and soil covering pressure wheel can be synchronized. The lifting adjustment makes it easy to adjust the depth of suppression, so that the sowing depth of peanut seeds can adapt to soil conditions of different textures. Since the distance between the leveling roller and the soil-covering suppression wheel remains unchanged during adjustment, it is helpful to avoid covering the soil-pressing wheel. Excessive suppression ensures the emergence rate of peanut seeds.
