Abstract

The utility model relates to an injector for trees, which belongs to a tree maintenance device. The original similar devices have the defects of power shortage or physic liquor overflow, narrow application range, serious liquid waste and environment pollution. The utility model adopts large power for taking physic liquor and simultaneously jetting the physic liquor; with the peculiar device as a fixer, the utility model has the advantages of wide application, no liquor overflow, simple structure and low cost.

Description

A kind of tree injection device

A kind of tree injection device belongs to the forest maintenance of equipment.

Existing same category of device kind is a lot, but the power that has is less, can't be used for the harder trees of quality; The then liquid that has injects unable, slow; Simultaneously, because of the design of power bracing or strutting arrangement is unreasonable, liquid spill during feed liquor, waste soup, contaminated environment.

The utility model is exactly at above-mentioned deficiency, adopts hydraulic power to penetrate into syringe needle, and this power is used for liquid injects, simultaneously the strong point is placed the method on the trees, thereby has overcome above-mentioned shortcoming.

The utility model is by injection needle part (1), be positioned at the power section (2) of the relative end of injection needle, be provided with the interface (8) that is connected with liquid container, one end stretches out shell (4), the liquid injection system (3) that other parts are positioned between injection needle (1) and the power section (2) and are connected with ad hoc fashion with power section, the cylindrical outer cover (4) that radially contains aforementioned three parts is formed, fixedly connected between the support section of power section (14) and the shell, near the interface (8) of liquid injection system, be provided with liquid switch (5), with the corresponding shell of liquid injection system interface (8) on have slideway (13), it is characterized in that: further comprising the device fixator (6) that is fixed on the shell (4); Simultaneously, liquid injection system adopts the cylinder piston structure, the top thick stick (12) of its piston (7) one ends and power section fixes, have fluid passage (9) in other parts, it is connected with liquid container and cylinder body (10) and syringe needle (1) and extends within the syringe needle, in upper end and the exterior of syringe needle near the top; And on the top of power section thick stick (12), be provided with piston and promote handle (11), the shell corresponding site has for its slideway that moves up and down.

The tree injection device that adopts such scheme to make, owing to can utilize external impetus that liquid is pressed within the trees, so pressure is big, speed is fast, and the device fixator is supported on the trees power, so can be when improving syringe needle greatly and thrusting power, syringe needle is squeezed on the trees tightly, cooperates big pressure and inject liquid fast, prevented liquid spill.Therefore can be applicable to seeds more widely, especially hard such as fruit tree, elm trees preferably.

Below, in conjunction with the accompanying drawings, be described further with regard to embodiment of the present utility model.

Fig. 1 is that the master of present embodiment looks complete section figure;

Fig. 2 is that the A of present embodiment is to view;

As shown in Figure 1, injection needle 1 is connected with liquid injection system 3, and the interface 8 of fluid passage 9 one ends in the liquid injection system communicates with liquid container, and the other end communicates with cylinder body 10, and outlet is in the both sides, upper end of syringe needle 1; The motion of external part 8 when the slideway 13 between liquid injection system and the shell is used for syringe needle and moves up and down; Liquid switch 5 does not adopt check valve and with the switch that can bear big pressure, flows backwards when avoiding liquid to be pressed into trees; Interface 8 can screw with liquid container and be connected; Being connected and fixed of external impetus and this device, the inside tapping that in this example is and this crust of the device 4 outside at the hydraulic jack lifting column be mutually to be threaded, the QVL-16 formula jack of marine jack company production on this example adopts.One end of piston 7 and the top thick stick of power section 2 12 are fixedlyed connected by fastening bolt; On top thick stick 12, have a hole 15, externally insert a reinforcing bar when the time comes and can after releasing oil pressure, promote this piston downwards, spur the piston 7 of liquid injection system and suck liquid, simultaneously, separate a microscler notch so that this catch bar moves up and down in shell 4 phase portions.

As shown in Figure 2, the device fixator of this example 6 adopts the pulley structure that is fixed on the shell 4 and the retainer ring of a relative end, adorns a locking device commonly used on pulley, as ratchet; Penetrate steel wire rope by the pulley aperture, detour and bind trees, the retainer ring that is fixed in shell one end in the other end by wire clips is realized fixing between this device and the trees, or at steel ball of a weldering of steel wire rope, fix a concavity holder that is claw-like on the shell, bead is embedded in the dimple, realize fixing between them.

The using method of this device is, opens capping, and hydraulic jack is transferred to initial position; This device is fixed on the trees scrolling pulley, locking steel wire rope with device fixator 6; Start jack syringe needle 1 is thrust trees, release oil pressure, open liquid switch 5, spur piston downwards and promote handle 11, liquid is sucked in the pressure cylinder 10 of liquid injection system; Closing liquid switch 5 starts jack, and the liquid master is injected among the trees.Because the device fixator is squeezed in syringe needle on the trees tightly, liquid filling pressure is bigger again, so liquid that can not overflows.
