Problems solved by technology

At present, the rice seeding methods for direct seeding of rice are mainly divided into mechanical type and pneumatic type. The mechanical seed metering device mostly uses a hole or grooved wheel type seed metering device to change the size of the hole or grooved wheel, thereby realizing the control of the seeding amount. However, it is impossible to precisely control the broadcast volume
The method of changing the sowing amount of the existing pneumatic seed metering device is mostly to replace the seed metering plate. This method needs to dismantle the seed metering device and install it again. The steps are cumbersome and highly professional
When working in the field, it is impossible to adjust the seeding rate conveniently and quickly

Abstract

The invention discloses a pneumatic seeding unit with the adjustable seeding rate. The pneumatic seeding unit comprises a seed box, a connecting part, a seeding casing, a seed discharging device, a seeding pipe, a seeding disc, a flange, a seed sucking casing, a brush and a seeding shaft, wherein the seed box is connected with the seeding casing trough the connecting part, the seed discharging device is arranged on one side of the bottom of the seeding casing, the seeding pipe is arranged on the other side of the bottom of the seeding casing, the seeding casing and the seed sucking casing are fixedly connected, the seeding disc is arranged in a space defined by the seeding casing and the seed sucking casing, the seeding disc is closely attached to the seed sucking casing, and the brush is arranged on the seed sucking casing. The pneumatic seeding unit is simple in structure, can allow convenient and rapid adjustment of the seeding rate, has a large seeding rate adjustment range and has high adaptability to different rice varieties.

Description

technical field [0001] The invention relates to the technical field of agricultural seeding, in particular to a pneumatic seed metering device with adjustable sowing rate. Background technique [0002] Rice direct seeding is a sowing technology that directly sows rice seeds in the field, which has the advantages of labor saving and low cost. At present, the rice seeding methods for direct seeding of rice are mainly divided into mechanical type and pneumatic type. The mechanical seed metering device mostly uses a hole or grooved wheel type seed metering device to change the size of the hole or grooved wheel, thereby realizing the control of the seeding amount. However, it is impossible to precisely control the fine and small amount of broadcast. The method of changing the sowing amount of the existing pneumatic seed metering device is mostly to replace the seed metering disc. This method needs to disassemble and reinstall the seed metering device, and the steps are cumbersom...
