Field fertilizer applicator assorted with four-wheel tractor

Abstract

The invention discloses a field fertilizer applicator assorted with a four-wheel machine. The field fertilizer applicator assorted with the four-wheel tractor comprises a connection rack and land wheels, wherein the connection rack is connected to the four-wheel tractor; the land wheels are used for supporting and walking; the land wheels are mounted at two ends of a land wheel shaft of the connection rack; a fertilizer box of a rectangular structure is arranged on the connection rack; a fertilizer discharging bottom hole is formed in the bottom of the fertilizer box and connected with a fertilizer applying box below the fertilizer box; the land wheel shaft is connected with a fertilizer shifting shaft in the fertilizer applying box by virtue of a chain; a shifting wheel with an axial groove in the outer wall and a shifting block with an axial baffle on the outer wall are mounted in the fertilizer applying box; the shifting wheel is connected with one end of the shifting block in the axial direction in a sleeving manner; the fertilizer shifting shaft penetrates into shaft holes of the shifting wheel and the shifting block; the inner wall of the shaft hole of the shifting wheel is connected with the outer wall of the fertilizer shifting shaft; the shifting wheel and the shifting block are arranged on a fertilizer applying path of the fertilizer applying box; a fertilizer quantity adjusting handle is connected to one end part of the fertilizer shifting shaft. The fertilizer applying quantity can be adjusted by the fertilizer quantity adjusting handle, so that the purpose of quantitatively applying fertilizers can be achieved, and fertilizers are relatively uniform during sowing.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and particularly relates to a field fertilizer applicator matched with four wheels. Background technique [0002] Before the crops are planted, chemical fertilizers must be sprinkled on the fields, and then the fields are planted. The traditional method of fertilization is to sprinkle chemical fertilizers manually, which not only cannot catch up with the needs of fertilization in large fields, but also the fertilization is uneven and cannot be quantified. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a field fertilizer applicator matched with four wheels, which can complete the fertilizer application quantitatively and uniformly. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A field fertilizer applicato...

Problems solved by technology

[0002] Before the crops are planted, chemical fertilizers must be sprinkled on the field, and then the land is sown. The traditional fertilization method is artificially sprinkled with chemical fertilizers, which not only cannot meet the needs of large-scale fertilization, but also is uneven and cannot be quantified.
