Pump-injection-type fertilizer application device

Abstract

The invention relates to a pump-injection-type fertilizer application device, which is characterized in that the pump-injection-type fertilizer application device comprises a base, a power device, a fertilizer quantity adjusting device, a cylinder body bracket, a piston cylinder and a fertilizer bucket; the power device, the fertilizer quantity adjusting device, the cylinder body bracket and the piston cylinder are arranged on the base; the fertilizer quantity adjusting device comprises a scale crank, a travel adjusting screw, a connecting rod bolt, a connecting rod and a connecting rod device, the scale crank is connected with the output end of the power device, the travel adjusting screw is engaged with the connecting rod bolt through threads, and the travel adjusting screw and the connecting rod bolt are arranged on the scale crank; the connecting rod is connected with the connecting rod bolt and the connecting rod device, the connecting rod device is arranged in the cylindrical body of the cylinder body bracket and the cylinder body of the piston cylinder is also arranged in the cylindrical body; one end of a plunger is connected with the connecting rod device, and the other end of the plunger is arranged in the cylinder body, is matched with the cylinder body, moves back and forth and is used for sucking and draining fertilizer solution; and a fertilizer solution inlet and a fertilizer solution outlet are arranged on the cylinder body, the fertilizer solution inlet is connected with the fertilizer bucket through a pipeline and the fertilizer solution outlet is connected with a fertilizer injection nozzle through a pipeline. The pump-injection-type fertilizer application device is convenient to operate and can be used as a special fertilizer application / injection device in agricultural irrigation systems or agricultural irrigation equipment such as center pivot sprinkling machines.

Description

technical field [0001] The invention relates to a fertilization device, in particular to a pump-injection fertilization device for circular sprinkler irrigation and fertilization operations, and belongs to the field of modern agricultural water-saving technology. Background technique [0002] The best technology recognized in the world today to improve the utilization rate of water and fertilizer resources is the integrated fertigation technology, which has become an important feature of modern intensive irrigation agriculture. Applying the sprinkler and micro-irrigation system to realize the coupling operation of irrigation and fertigation can precisely control the fertilization time, fertilization amount, fertilizer concentration and the ratio of nutrient elements, improve the utilization rate of water and fertilizer, and minimize the pollution to the environment. The traditional method of applying chemical fertilizers has low fertilization precision, and its fertilizer ut...

AI Technical Summary

Problems solved by technology

Hydraulically driven fertilizer injection pumps, such as proportional fertilization pumps, are relatively expensive, and the fertilizer injection flow rate is affected by the working pressure, so the scope of application is limited, and it is mainly used in spraying and micro-irrigation projects such as multi-span greenhouses; Pumps are not currently used on center pivots
