Abstract

The utility model relates to a hydraulic chemical fertilizer deep applicator, belonging to an agriculture fertilizer drilling device. The hydraulic chemical fertilizer deep applicator is characterized in that an air chamber is disassembled. A spring 1 and a press screw 2 are arranged on a liquid outlet valve. The sprayer 13 of an adjustment block 4 is added on a piston rod 3. The utility model is also composed of a deep applicator composed of a liquid infusion pipe 5, a handle 6, a hollow connection rod 7, a pedal 8, a depth plate 9, a metering-orifice pipe 10, and an inserting knife head 11. The utility model has the advantages of simple structure, reliable working performance, low manufacture cost, convenient operation, etc. The dripping of liquid fertilizer in a jet orifice can be effectively overcome. The utilization rate of the fertilizer can be enhanced.

Description

The fluid pressure type fertilizer deep placing device

The utility model relates to a kind of fluid pressure type fertilizer deep placing device, belongs to agricultural fertilizer apparatus.

Existing liquid fertilizer deep applicator is existing multiple, as CN87103620.7, and disclosed technical scheme such as CN91231328.5, such scheme all can reach liquid fertilizer deep placement purpose, but still has complex structure, operation inconvenience, shortcomings such as spray orifice liquid fertilizer water clock.

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of fluid pressure type fertilizer deep placing device is provided.

The utility model is achieved in that this fluid pressure type fertilizer deep placing device is made up of sprayer 13 and deep applicator.Sprayer 13 is known sprayer, adds shock mount 1 and housing pin 2 at the liquid valve place of sprayer 13, on the piston rod 3 of sprayer 13, install the impulse stroke of control piston additional and reach control fertilizing amount adjustment piece 4.Deep applicator is by woven hose 5, handle 6, and connecting rod 7, pedal 8, depth control shoe 9, metering-orifice pipe 10 inserts cutter head 11 compositions such as grade.Connecting rod 7 is the garden bar of a hollow, inserts cutter head 11 and adopts the little point of a knife shape of resistance, is provided with the metering-orifice pipe 10 that reduces spray orifice liquid fertilizer water clock at spray orifice.Deep applicator is partly made with material known and conventional method.

Accompanying drawing is the utility model structural representation.

The utility model is described in further detail below in conjunction with accompanying drawing: this fluid pressure type fertilizer deep placing device is made up of sprayer 13 and deep applicator.Air chamber with sprayer 13 during use removes, add shock mount 1 and housing pin 2 at the liquid valve place of liquid pump 12, install the impulse stroke of control piston additional on the piston rod 3 in liquid pump 12 and reach the adjustment piece 4 of controlling fertilizing amount, and the woven hose 5 of the drain pipe of sprayer 13 with handle 6 ends be connected, can use.During fertilising, right hand handle hand 6 also makes the point of a knife shape of deep applicator insert cutter head 11 insertion soil layers, and the degree of depth of inserting soil layer is by depth control shoe 9 controls.The handle that left hand shakes sprayer 13 promotes liquid pump 3, and this moment, liquid fertilizer pressure backed down liquid valve spring 1 inflow woven hose 5, and metering-orifice pipe 10 to the spray orifice through preventing water clock sprays into soil.

This practicality newly existing compared with prior art, have simple in structure, reliable working performance, low cost of manufacture, operation letter Just, can effectively overcome the water clock of spray orifice liquid fertilizer, improve the advantages such as utilization rate of chemical fertilizer.

Claims

A kind of fluid pressure type fertilizer deep placing device is made up of sprayer 13 and deep applicator, it is characterized in that:
