Abstract

The invention discloses a lever-type sowing-depth-adjustable hole sowing seed metering single body, and belongs to agricultural machinery. A sowing depth adjusting and controlling block with a pin shaft and a lead screw with a hand wheel are installed on a rectangular barrel type single body frame, the lead screw is in threaded connection fit with the sowing depth adjusting and controlling block, a lever with a strip-shaped through hole is inserted into a center hole of the sowing depth adjusting and controlling block, the pin shaft is inserted into the strip-shaped through hole, a rigid seed guide pipe with a duckbilled hole opener mounted at the bottom end is inserted into the rectangular barrel type single body frame and is fixedly arranged on the left end part of the lever, a driving rod sleeved with a pressure spring is inserted into the rectangular barrel type single body frame and is hinged with the right end of the lever, a motor and a seed metering device assembly with a seed box are arranged on the rectangular barrel type single body frame, a driving belt wheel is fixedly arranged on a seed metering shaft of the seed metering device assembly, a linkage shaft with a driven belt wheel and an eccentric wheel is arranged on the rectangular barrel type single body frame through a bracket, and the driving belt wheel and the driven belt wheel are sleeved with a transmission belt. The single body realizes hole sowing depth adjustment, and is high in adjustment precision, simple in adjustment operation and high in applicability.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a lever-type structure seed-discharging unit with adjustable sowing depth for hole sowing. Background technique [0002] Hole sowing is a precision sowing method with good agronomic performance. In this method, duckbill hole openers are often inserted into the soil to complete hole construction and seed input and sowing operations. The depth of seed sowing cannot be adjusted. Immutable. However, in actual production operations, different crop varieties have different requirements for sowing depth, and different soil conditions also vary and change the depth of seed sowing. The requirement of adjusting and changing the depth of hole planting under certain conditions has poor operation adaptability, single performance and low utilization rate. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art,...
