Sand pressing device for multifunctional celery seeding machine

Abstract

The invention provides a sand pressing device for a multifunctional celery seeding machine and belongs to the field of agricultural machinery. The sand pressing device comprises a sand bin, a sand loosening shaft, a stirring shaft, a gear box, a hydraulic pump and a sand baffle plate, wherein the sand loosening shaft and the stirring shaft are mounted in side plates in two sides of the sand bin, forward crescent blades and reverse crescent blades are staggered on the sand loosening shaft, and sand scrapers are arranged in the positions, corresponding to sand discharge ports of the sand bin, on the sand loosening shaft; longitudinal stirring rods and horizontal stirring rods are staggered on the stirring shaft; the gear box and the hydraulic pump are mounted on the external facade of the side plate on one side of the sand bin, the sand loosening shaft and the stirring shaft are coaxial with a driving gear shaft and a driven gear shaft in the gear box, and the hydraulic pump is mounted at one end of the driving gear shaft. According to the sand pressing device, the sand stirring speed is increased, the sand discharge ports are prevented from being blocked by wet caked sand, the sand discharge efficiency is high, and the sand pressing quality is good.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a sand pressing device for a multifunctional celery seeder. Background technique [0002] Ningxia Xiji is mainly planted with celery and vegetables. As one of the main channels for poverty alleviation in poverty-stricken areas, the cultivated area of ​​celery exceeds 80,000 mu. Due to the small size of celery seeds, weak emergence, large seeding volume, and high cultivation density, standardized production and mechanization levels have always been low. In order to comprehensively improve the production and cultivation capacity of celery, in the cultivation of celery, the whole crop mulching, drilling, sowing, sand covering, etc. must be mechanized. The sand-covering device is used to cover the sand after drilling holes on the covering film to avoid affecting the survival rate of the seeds due to the exposure of the seeds.

Problems solved by technology

However, there is only one stirring and loosening shaft for sand mixing in the sand cover device installed on this machine. For the wet sand that is easy to agglomerate, the stirring force is small, and the sand is easy to block the sand outlet; The crescent blade faces one side, and the sand tends to flow to one side of the sand bin during stirring, and the sand loosening shaft is located at the sand outlet without a sand scraper for cleaning the sand outlet, which will affect the sand outlet and sand cover effect
