Problems solved by technology

At present, in order to adjust the seeding rate, the socket wheel seed metering device mainly relies on adjusting the seed cleaning brush, adjusting the seed limiting plate or replacing the seeding wheel to adjust the seeding rate. However, due to the adjustment range of the seed cleaning brush and the seed limiting plate Therefore, adjusting the sowing rate by adjusting the seed cleaning

Abstract

The invention provides a combination hole seeder capable of adjusting the seeding quantity, which comprises a casing and a seed-metering wheel device; the casing is provided with a seed feeding chamber; and the seed-metering wheel device is mounted in the casing, and comprises a transmission shaft, a combination hole wheel, an adjusting positioning mechanism and a hole wheel casing, wherein the combination hole wheel is mounted on the transmission shaft, and at least two groups of holes in different sizes are arranged on the circumference of the combination hole wheel; the adjusting positioning mechanism is mounted on the transmission shaft, and connected with the combination hole wheel; the hole wheel casing is sleeved on the periphery of the combination hole wheel, at least part of the hole wheel casing is placed in the seed feeding chamber, a plurality of external through holes are arranged on the circumference of the hole wheel casing, and are larger than one smaller group of the two groups of holes; and when the combination hole wheel rotates by adjusting the adjusting positioning mechanism, the external through holes are selectively communicated with one group of the groups of holes. The combination hole seeder has the advantages of being capable of adjusting the seeding quantity, large in adjusting range, and convenient to adjust.

Description

technical field [0001] The invention belongs to the technical field of sowing crops, and in particular relates to a combined hole seed meter with adjustable sowing rate. Background technique [0002] In the sowing of crops, most crops such as corn, soybean, sugar beet, sorghum, and cotton adopt precision sowing, and grains such as rice and wheat are gradually promoting precision sowing, because precision sowing can save labor for seeds and seedlings, and can make seedlings evenly distributed, reaching The seedlings are neat, strong and uniform, which is conducive to stable and increased production. The types of point (hole) sowing and metering devices used in production include air suction type, air blowing type, air pressure type, horizontal disc type, inclined disc type, spoon type, hole belt type, socket wheel type, etc. . According to the way of filling seeds, the seed metering devices can be roughly divided into two categories: pneumatic type and mechanical type. [...
