Position-adjustable auxiliary device for liquid fertilizer spraying work

Abstract

The invention discloses a position-adjustable auxiliary device for liquid fertilizer spraying work. The position-adjustable auxiliary device comprises a main bearer and an accessory bearer, wherein the main bearer comprises a main bearing panel, a main bearing frame and a main bearer gear system; the accessory bearer comprises an accessory bearing frame, guide wheels and an accessory bearer sliding gear. The main bearer and the accessory bearer are provided with liquid fertilizer pipelines respectively, and each liquid fertilizer pipeline is provided with a plurality of valve sprayer devices at intervals. A fertilizer spraying system outputs fertilizer liquid through valves, and then the fertilizer liquid enters fertilizer inlets of the accessory bearer and the main bearer. According to the position-adjustable auxiliary device for the liquid fertilizer spraying work, through a multi-valve control structure, in the topdressing and pesticide-spraying processes, the valves can be flexiblyopened or closed according to the actual work situation, and the problem that the topdressing position range is too wide, and waste is caused is solved. By using a gear linkage design, stretching andretraction of a fertilizer spraying support are achieved in the way that a driving gear drives an accessory gear, it can be achieved that wingspans of the fertilizer spraying support are quickly folded, and the problem about space occupation of the fertilizer spraying support is solved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilization equipment, in particular to a position-adjustable auxiliary device for spraying liquid fertilizer. Background technique [0002] In the field of planting, in order to timely supplement the required nutrient elements in each period of the crops, the farmer will perform topdressing operations, and the topdressing operations are generally carried out on the crop canopy. In the process of topdressing, the fertilizer spraying frame on the fertilizer spraying machine is used for topdressing. However, the existing fertilizer spray racks have problems such as difficulty in stretching and folding, excessive topdressing layer range, limited loading capacity, or limited loading control for supporting operating equipment, which in turn affects the effect of topdressing and fertilizer waste.
