Description

Injection type liquid fertilizer deep applicator

[technical field]

The utility model belongs to fertilising farm machinery field, particularly a kind of injection type liquid fertilizer deep applicator.

[background technology]

All carry out at present fertilising, medications such as trees, flowers and plants and crops, farmland on the surface, as application number 03243651, name is called " fertilizer applicator ", and it is made of the case that topdresses, suspension arm, fertilizer producing tube, connection movable joint, rice crop-poking wheel rod etc.; Fertilizer can be executed ground through top dressing hole uniformly, it is a little accurate to topdress.Can only cover ground again with the fertilising medication of hoe wound ground as the needs deep fertilization, be the time-consuming effort of taking a lot of work like this, and weak effect can not keep the permanently effective preservation on crop of fertilizer and agricultural chemicals effectively again, and bringing into play it should have effect.People have developed some fertilising medicine machineries for this reason, but still can not satisfy fertilising prescription face needs in the prior art fully.

[summary of the invention]

The purpose of this utility model be to provide a kind of structure more simple, can deep fertilization, the injection type liquid fertilizer deep applicator of dispenser.

The utility model is achieved in that it comprises container, flexible pipe, check valve, after container and flexible pipe one end interface place put into check valve, container and flexible pipe are joined, execute materials device by injection-tube, check valve, fluid injection syringe needle, transfer dark plate, piston, pull bar, spring, spiral bayonet socket, handle to form.The mode of linking to each other: described injection-tube lower end links to each other with fluid injection syringe needle screw by check valve, the fluid injection syringe needle is provided with transfers dark plate, the inlet pipe is established in the injection-tube middle and lower part, the inlet pipe links to each other with flexible pipe, injection-tube inner carrier chamber is provided with piston, piston connects pull bar, and pull bar flexibly connects the spiral bayonet socket, connects spring between the top cover of spiral bayonet socket and injection-tube.

This special construction of the utility model compared with prior art, have save time, saving of labor, laborsaving, simple in structure, advantage such as easy to carry, of many uses can be executed fertile medicine on the target effectively.
