Plant avoidance type appropriate fertilizer applicator

Abstract

The invention designs a plant avoidance type appropriate fertilizer applicator, which relates to the field of agriculture. The plant avoidance type appropriate fertilizer applicator is mainly characterized by comprising a hooking part for hooking the applicator with a tractor, a plant avoidance part and an appropriate fertilizer application part. The fertilizer applicator is hooked behind the tractor in a three-point suspension manner; when a rightwards transverse V-shaped induction bar of the plant avoidance part touches a plant, two telescopic springs deform, an avoidance hydraulic motor is controlled to start and a furrowing blade is driven to turn so as to realize plant avoidance; a stirring shaft and stirring rods are driven by a land wheel of the appropriate fertilizer application part through a chain wheel and a chain, so that fertilizer is stirred to prevent caking; the rotation speed of a fertilizer feeding hydraulic motor is adjusted to realize appropriate fertilizer application according to soil fertility and crop requirements; the machine space and the operation lines can be adjusted according to the tractor and parcels; the furrowing blade is changed into a sub-soiling shovel, so that sub-soiling fertilizer application can be performed, and the universality and the utilization rate of the applicator are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an appropriate amount of fertilizer applicator for avoiding plants. Background technique [0002] Precision agriculture is the development direction of modern agriculture in the future, and the rational use of chemical fertilizers is one of the key technologies of precision agriculture. According to statistics, my country's chemical fertilizers account for 30% to 40% of the increase in crop production. Therefore, chemical fertilizers are an important measure to ensure food security. However, for a long time, my country's extensive agricultural management mode has caused the use of chemical fertilizers not to be rationally and effectively used, and the use of chemical fertilizers has increased year by year, ranking first in the world. However, the utilization rate of chemical fertilizers is only about 30%, which is equivalent to 70% of excess chemical fertilizers e...

Problems solved by technology

[0003] At present, most of the fertilizer applicators at home and abroad have a fixed amount of fertilizer, or test the amount of fertilizer in the open space after adjustment, which is troublesome and inaccurate, resulting in waste of fertilizer and pollution; at the same time, when fertilizing between crop rows, crop plants cannot be avoided, and it is easy to shovel drop seedlings
