Auxiliary machine frame matched with positive and negative air pressure combined type pneumatic seeding unit

Abstract

The invention discloses an auxiliary machine frame matched with a positive and negative air pressure combined type pneumatic seeding unit, wherein the lower side beams and the upper side beams are connected by bolts and fixed on a side plate of a main machine frame; a lower front beam is welded on the lower side beams at the two sides; a front supporting rod connects the lower front beam and a positive pressure air pipe into one body by welding, is welded with a connecting plate, is connected with the main machine frame with bolts used by the connecting plate, is matched with the connection ofthe lower side beams and the upper beams as well as the side plate of the main machine frame, and fixedly connects the positive and negative air pressure combined type pneumatic seeding unit by bolts; the positive pressure air pipe and the negative pressure air pipe are integrally connected with the upper side beams at the left end and the right end by welding; a rear supporting rod connects a lower rear beam and the negative air pipe by welding; and a cross supporting rod is connected with the lower front beam and the lower rear beam by welding. The auxiliary machine frame has simple structure and convenient operation, adopts bolt connection, has convenient disassembly, is applicable to the positive and negative air pressure combined type rape seed seeding unit in precise quantity and solves the problem of arrangement and installation of air pipes of the positive and negative air pressure combined type pneumatic seeding unit.

Description

technical field [0001] The invention relates to the technical field of seeders in agricultural machinery, in particular to an auxiliary frame matched with a combined positive and negative air pressure pneumatic seed metering device, and the auxiliary frame is also suitable for air pipe arrangement and installation of other pneumatic seed metering devices. The key point is to solve the problem of air pipe layout and installation of positive and negative air pressure combined pneumatic seed metering device. Background technique [0002] my country's rapeseed planting area and total output both rank first in the world. The traditional rapeseed cultivation methods in my country mainly include seedling cultivation and transplanting and artificial direct seeding. Both of them have disadvantages such as large labor input, many operating procedures, low production efficiency, and large waste of good seeds, resulting in poor comprehensive benefits of rapeseed production. In order to...
