Corn integrated machine using separable air-suction type seed-metering device

Abstract

The invention discloses a corn stand-alone machine using a detachable air-suction seed metering device, which includes a frame and a pressing wheel. There is an air-suction seed metering device under the pipe, a profiling frame at the front end of the frame, a depth adjustment screw at the lower end of the profiling frame, a ditch opener under the depth adjustment screw, and a mounting plate on the ditch opener. There is a soil retaining board behind the ditch, and a soil cover card is arranged behind the soil retaining board. The ground wheel connecting arm is arranged on the side of the frame, and a suppression rod is installed in the middle of the ground wheel connecting arm. A suppressing wheel is arranged under the arm, and a ground wheel shaft is arranged in the middle of the suppressing wheel. The beneficial effect is that: the sowing of the seed metering device can be individually controlled through the clutch, which is convenient for use during sowing and reduces waste of seeds.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a single corn machine using a detachable air suction seed metering device. Background technique [0002] The rapid development of modern agriculture, with the transfer of land, agriculture has developed into a large-scale farm. The traditional agricultural machinery is small, and the operation efficiency is slow, which is not suitable for the needs of agricultural development, which promotes the continuous development of large-scale agricultural machinery. The Chinese patent with the application number 201520231530.7 discloses a corn and wheat dual-purpose no-tillage fertilization seeder, which includes a rotary knife ditching device and a driving ground wheel located at the front end of the frame, a fertilizer spreading device located on the frame, and a rotary knife with variable speed. The box and the corn sowing transmission gearbox, and the corn sowing dev...

Problems solved by technology

In the above-mentioned patents, the corn sowing device is in the form of a linkage, that is, several corn sowers run synchronously, and cannot stop when there is no need to plant seeds at the edge of the field. Repeated sowing causes waste of seeds, and after the seeds germinate, manual shaving is required. seedlings to reduce the density of corn seedlings, a waste of manpower and time
