Water-fertilizer integrated rotary tillage row-opening fertilizer applicator

Abstract

The invention relates to the field of agricultural machinery, and particularly discloses a water-fertilizer integrated rotary tillage row-opening fertilizer applicator. The fertilizer applicator comprises a rack, a fertilizer applying device with a fertilizer applying part and a mixing part, a soil opening device with a detachable movable plowshare, a rotary tillage device, a bottom furrow ploughwith a plowshare and a mud scraping plate, a supporting rod, a driving device with a speed regulating valve, a controller and a water applying part. According to the invention, land can be dug throughthe bottom furrow plough, a fertilization deep ditch can be dug through the plowshare, then the fertilization deep ditch is filled with soil again through the mud scraping plate to form ridges, fertilizer loss caused by exposure of fertilizer can be prevented accordingly, and the field ridges can effectively prevent the fertilizer from making direct contact with seed stems to cause seedling burning; and the fertilizing device can achieve water and fertilizer double application, not only can independently apply a solid fertilizer, but also can apply water to be mixed with a fertilizer, so thatthe solid fertilizer can be mixed with dry soil more easily, and the controller can scientifically control the fertilizing amount through a speed measuring device.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a water and fertilizer integrated rotary tillage and running fertilizer applicator. Background technique [0002] During the sugarcane planting process, the sugarcane field needs to be plowed and harrowed for soil preparation, and then fertilized in rows, and finally the sugarcane stems are planted in the row furrows, and the planting is completed by covering them with soil. [0003] But existing sugarcane plantation, there will be following problems: [0004] 1. With the method of pre-opening row planting, the soil in the row ditch is not fine enough, which makes it difficult for sugarcane to emerge; and it is impossible to apply deep fertilizer and cover soil at the same time, which increases the cost of planting. [0005] 2. Using the existing planter to plant directly, there are 1) the planting depth is not enough, the sugarcane is easy to lodging, and the drought resis...

AI Technical Summary

Problems solved by technology

[0004] 1. With the method of pre-opening row planting, the soil in the row ditch is not fine enough, which makes it difficult for sugarcane to emerge; and it is impossible to apply deep fertilizer and cover soil at the same time, which increases the cost of planting

[0005] 2. Using the existing planter to plant directly, there are 1) the planting depth is not enough, the sugarcane is easy to lodging, and the drought resistance is not strong; 2) the soil in the planting ditch is not fine enough, which affects the emergence of seedlings; 3) The distance between the fertilizer and the sugarcane root is too close, which is prone to burn 4) Due to the use of solid fertilizers when fertilizing, it is not easy to combine with dry soil; 5) The amount of fertilization cannot be precisely controlled, resulting in waste of fertilizers
