Abstract
The utility model relates to a soil injector, utilizing the principle of the hydraulic device, which is characterized in that: a piston assembly is arranged at the middle of the injector, two one-way valve are respectively arranged at the upper part and the lower part of the injector; when the injector is loaded on the back of the operator, the piston moves upwards automatically, the upper one-way valve is opened, the liquid in the storage tank is sent to the pressure chamber; when the operator presses the handle, the piston assembly moves downwards, the upper one-way valve is shut, while the lower one-way valve is opened, the pesticide, the liquid fertilizer or water is push into soil through the injector needle by the pressure.
Description
Affiliated technical field
The utility model relates to a kind of agricultural fertilizer and irrigates facility, and it adopts the method for fixed-point injection that agricultural chemicals, liquid fertilizer or water are injected directly into plant root.
Background technology
At present, agricultural fertilizer and irrigation all adopt large tracts of land to spray, and perhaps dig pit earlier and agricultural chemicals, liquid fertilizer or water are put into wherein again.This not only wastes a large amount of agricultural chemicals, liquid fertilizer or water.Plant root produces effects less simultaneously.
Summary of the invention
The utility model provides a kind of soil injection device that agricultural chemicals, liquid fertilizer or water can be injected directly into plant root.It is characterized in that: pressure chamber import and export both sides are respectively installed one and are opened the opposite steel ball of direction and make check valve, and liquid transmission pipeline passes through in the middle of piston, and the handle physical slot is in upper all the time.It is a principle of utilizing hydraulic means, in the middle of piston component places, upper and lowerly respectively establishes a check valve, piston up-down, and upper and lower check valve is alternately opened, and makes agricultural chemicals, liquid fertilizer or water be pushed into soil under pressure.
The beneficial effects of the utility model are:
1, only need one man operation, the operator saves time, saving of labor, laborsaving
2, save agricultural chemicals, liquid fertilizer or water, improve its availability
3, be applicable to crops such as fruit tree, vegetables, cotton.
Description of drawings:
Below in conjunction with Figure of description and embodiment the utility model operation principle is further specified, Fig. 1 is the vertical section structural map of this utility model embodiment.Among Fig. 1: 1, syringe needle; 2, shell; 3, go up shell; 4, core bar assembly; 5, support; 6, handlebar; 7, hand-operated valve; 8, pedal; 9, housing; 10, little spring; 11, piston component; 12, following check valve; 13, go up check valve; 14, cylinder body; 15, big spring; 16, left handle; 17, right handles; 18, elbow; 19, baffle plate; 20, small shell; 21, cap nut; 22, connect mouth; 23, pressure chamber
Specific embodiments
Operator's disk 8 that tramps with one's feet, it is 20CM that syringe needle 1 enters soil depth, piston component 11, core bar assembly 4 and left and right handle 16,17 move upward under big spring 15 effects, owing to be installed in the sealing function of the following check valve 12 of pressure chamber 23 import and export both sides, last check valve 13 and piston component 11, cause pressure chamber 23 vacuum to occur.At this moment, the liquid that the operator carries tank on the body utilizes potential action by connecing mouth 22, pushes check valve 13 open, enters and is full of pressure chamber 23 along piston component 11 center-aisles.The operator presses down and is in upper left and right handle 16,17 all the time, and the pressure of pressure chamber 23 compresses check valve 13, makes it to close.On the other hand, fluid pressure overcomes the power of little spring 10, pushes down check valve 12 open, and liquid enters soil by syringe needle 1 under the pressure effect of piston component 11.Hand-operated valve 7 is bleed valves, is responsible for releasing the pressure of pressure chamber 23.
Claims (3)
1. soil injection device, manually the upper/lower terminal of piston respectively has one to open the opposite steel ball of direction and make check valve, it is characterized in that:
A check valve is respectively installed in a, pressure chamber import and export both sides;
B, liquid transmission pipeline pass through in the middle of piston component;
C, handle physical slot are in upper all the time.
2. soil injection device according to claim 1 is characterized in that: described two one-way valve opens directions are opposite, liquid are full of or the discharge pressure chamber.
