Fertilizer application shovel

Abstract

The invention discloses a fertilizer application shovel and belongs to the technical field of agricultural machinery. The fertilizer application shovel comprises a deep loosening shovel and a fertilizer application device, wherein the fertilizer application device comprises a fertilizer guide box and a uniform fertilizer application structure; an outer top wall of the fertilizer guide box is fixedat the lower side of a shovel edge part; an inner cavity of the fertilizer guide box is a fertilizer containing cavity; a fertilizer feeding opening, communicated with the fertilizer containing cavity, is formed in the rear end of the fertilizer guide box; more than one fertilizer application opening is formed in a part, close to a front end part, of the fertilizer containing cavity; the uniformfertilizer application structure comprises a scraping plate and a reciprocating motion mechanism; the scraping plate comprises at least one group of scraping teeth acting on fertilizer in the fertilizer containing cavity; the scraping plate is connected with an inner top wall of the fertilizer containing cavity through a sliding connection structure; the reciprocating motion mechanism comprises adriving motor, a speed reducer and an eccentric shaft; the driving motor is in transmission connection with the eccentric shaft through the speed reducer; the eccentric shaft is in transmission connection with a front end of a connection rod and the rear end of the connection rod is hinged to the front end of the scraping plate. The fertilizer application shovel disclosed by the invention can be used for effectively dredging the fertilizer containing cavity, preventing the fertilizer feeding opening from being blocked and ensuring uniform fertilizer application on soil.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery. Background technique [0002] In recent years, in order to give full play to the effect of subsoiling and soil preparation on increasing crop production and income, subsoiling and soil preparation operations are being promoted across the country. The implementation of subsoiling and land preparation operations can effectively break the bottom of the plow, increase the thickness of the plow layer, improve the soil structure, loosen and ventilate the soil, store water and moisture, improve soil fertility, accelerate the accumulation of effective nutrients, improve the quality of cultivated land, and promote wheat and corn. The root system of other crops can take root and grow and develop, so as to achieve stable and high yield. [0003] For subsoiling full-layer fertilization operations, the fertilizer can be applied to the soil below 10cm from the ground surface to the bottom of th...

Problems solved by technology

[0004] At present, the existing subsoiling and soil preparation technology can apply the formula fertilizer into the soil at one time. However, due to the different soil return speeds caused by the different soil properties in different regions and the uncertainty of starting and stopping the tractor during the driving process, the fertilizer is divided into two parts. The layer is not obvious and the fertilization port is easy to block, resulting in uneven fertilization and other problems
