Caterpillar band recess next-to-ground precise seed discharging device

Abstract

The invention relates to a caterpillar band recess next-to-ground precise seed discharging device, and belongs to the field of agricultural machinery and equipment. The caterpillar band recess next-to-ground precise seed discharging device comprises a rack, wherein the rack is provided with a seed discharging cabin with a seed distribution hole; a seed discharging caterpillar band which can be connected with a driving mechanism is arranged in the seed discharging cabin; the lower part of the seed discharging caterpillar band corresponds to the position of the seed distribution hole; the caterpillar band is provided with at least row of recesses along the length direction of the caterpillar band; each group of recesses is connected through a seed unloading ditch; each seed unloading ditch forms an annular form along the length direction of the seed discharging caterpillar band; the width of each recess is greater than the width of the seed unloading ditch, and the depth of each recess is the same with the depth of the seed unloading ditch; the lower part of the seed discharging caterpillar band is provided with a sliver sheet; and one edge, which is far away from the seed unloading ditch, of the sliver sheet is fixed on the rear cabin plate of the seed discharging cabin. The caterpillar band recess next-to-ground precise seed discharging device changes a way of carrying out seed distribution after seed discharging into a way of simultaneously carrying out seed discharging and seed distribution, the seed discharging device is connected with a ditching device into a whole, a seed metering process and a seed distribution process are combined into a whole, so that a sowing quantity can be precisely controlled, and seedling space distribution can be precisely controlled.

Description

technical field [0001] The invention relates to a precision seed metering device with caterpillar grooves attached to the ground, which belongs to the field of agricultural machinery and equipment, and is suitable for sowing seeds of wheat, corn, soybeans, peanuts and other crops in a single row in a single row or in a row in multiple rows. [0002] technical background [0003] Traditional grain seeders, such as wheat, mostly use external grooved wheel fertilizer dischargers. The seeding rate is controlled through the seed metering device. After the seeds are discharged from the seed metering device, they are transported to the ditch opener through the seed delivery pipe, and then randomly scattered. in the seeding ditch. This kind of mechanical design separates the seed metering device from the opener, and separates the seed metering process from the seed distribution process. Although it can control the seeding rate more accurately, it cannot accurately control the spatial...

AI Technical Summary

Problems solved by technology

This kind of mechanical design separates the seed metering device from the opener, and separates the seed metering process from the seed distribution process. Although it can control the seeding rate more accurately, it cannot precisely control the spatial distribution of seedlings, and it is difficult to achieve precise sowing.

Although the finger clip seed metering device is used for crops such as corn, which has the function of single-grain on-demand sowing, which can accurately control the sowing amount and the seed row spacing, but it is difficult to realize small-grain seeds one-time due to the constraints of mechanical design.
