Description

Root manuring device

The utility model Root manuring device belongs to and the matching used a kind of agricultural tools of sprayer.Be applicable to fertilising, drought resisting and the elimination soil insect of dry crop.

In recent years, cost-saving synergistic, developing agriculture through science and technology becomes the main points of developing agricultural economy.For reaching cost-saving synergistic this purpose, must use scientific methods, rationally utilize chemical fertilizer, agricultural chemicals and water by certain instrument.For this reason, many products of making every effort to reach this requirement have appearred on the market.The patent No. is that 95220061.9 product " root syringe " is exactly a kind of (Fig. 1) wherein.At present, although this product is a kind of preferably in the like product, in practice, also exist following problem.

1. the position that is connected with sprayer is bad, inconvenience when causing operating.

2. valve sealing gasket unprotect device partly influences service life of parts.

3. the graduation mark on the gauge line easily comes off.

4. the water (flow) direction instability of impulse buoy influences the accuracy of metering.

5. dismounting is convenient inadequately.

6. the water clock of liquid can not get basic elimination.

7. pedal is because of fixedly being not easy to operation.

The purpose of this utility model just provides a kind of novel fertilising that is applicable to Dry crop, injection, drought resisting, and can overcome the Root manuring device of above shortcoming.The intensity height of this product, very accurate, the safety of metering, dismounting are very convenient, and use cost is low, and is applied widely, and the needle point apopore never stops up, and does not certainly have water clock.

The purpose of this utility model is achieved in that the hose coupling on 1. sprayers is connected with the transit joint of handgrip afterbody.2. a sealing gasket protector that can turn to is arranged on the handgrip switch.3. the gauge line outer surface has gold stamping scale.4. the liquid that enters gauge line is by after the rectifying valve, evenly, directionally impulse on transverse plane on the buoy.Between the needle point, thick conduit, fine duct, following, gauge line, handgrip all employing be threaded.6. in the conduit Drop-proof valve is housed, adorns one outward and can regulate embedded depth, again can be as the pedal depth stop of the usefulness of pedal.Needle point is two-way tapering, and there are three apertures at the middle part of handle, and afterbody is a screw thread, and after heat treatment is connected with fine duct.

Below in conjunction with description of drawings structure of the present utility model.

The utility model (Fig. 2) primary structure is divided into handgrip valve body, gauge line, following, injection catheter and needle point five partly.Needle point of the present utility model (1) is divided into tip and shank (Fig. 3), the tip is the two-way tape tapering, shank has screw thread and three ostium excurrenses, the maximum gauge of awl is bigger than the joint garden at three aperture places, earth did not enter aperture when assurance was buried, the conduit that buries simultaneously further enlarges the hole that needle point forms, add the opposite direction garden awl on the needle point, make conduit, when needle point leaves soil, can just tiltedly not make earth enter aperture because of conduit, needle point after heat treatment connects with the same fine duct of screw thread (2), and the intensity height is quick detachable.

Conduit of the present utility model is combined by thin tubulature (2) and thick long duct (5), uses fine duct laborsaving, and thick conduit can make the scope of application enlarge, and can select to use fine duct or thick conduit according to the crop root depth.

Pedal depth stop of the present utility model (3) is the assembly (Fig. 4) of pedal part and limit deep part, and is easy to operate.

Drop-proof valve of the present utility model (4) is to guarantee Root manuring device can not cause needle point (1) the liquid water clock to occur above pull of vacuum because of the moment gravity of interior the liquid of gauge line (9) when soil is transferred to.

Following (6) of the present utility model by conduit that is threaded (5) and gauge line (9), gauge line (Fig. 6) two ends are stress surface and seal by sealing gasket (7) that with the end face of garden dish an end of gauge line is an external screw thread, other end band tapering.Gauge line (Fig. 6) outer surface has gold stamping scale.

Buoy of the present utility model (8) is the garden cylindricality, interior sky, and garden week is gone up uniform four muscle, and little with the friction of realization and gauge line inwall, it is rapid when return to reach buoy simultaneously, makes operation more quick, and it is more accurate to measure.

Liquid rectifying valve of the present utility model (11) guarantee liquid can be evenly, directionally impulse dwindles error in dipping on transverse plane on the buoy.

Handgrip body part of the present utility model has threaded blind nut (10) at handgrip (18) and gauge line connecting place; Pin (17) connects together trigger (16), handgrip (18), return spring (15); the one sealing gasket protector (14) that can turn to is arranged on the trigger; the handgrip afterbody has a dismountable transit joint (19), at the passage place of handgrip sealing gasket (20) is arranged, union (screwed)bonnet (UB (12) and spool (13).

Operating process of the present utility model is: the hose coupling and the transit joint (19) of sprayer are linked to each other, in proportion water, chemical fertilizer or agricultural chemicals are packed in the water tank of sprayer, mix thoroughly.Then according to the depth of crop root, adjust the position of pedal depth stop (3), hand handgrip (18) or pin are stepped on pedal depth stop (3), with needle point, conduit thrusts the root of crop, pull trigger (16), sealing gasket resets after losing external force and forms passage, liquid enters rectifying valve (11) by the sprayer water tank through passage, liquid enters gauge line (9) and even after rectification, directionally impulse is on the last transverse plane of buoy (8), buoy is descended synchronously with liquid, observe the injection volume of liquid by the scale on the gauge line, liquid arrives three apertures of needle point (1) to the Drop-proof valve (4) through conduit cavity, inject crop root again, transfer to the conduit needle point, back and forth operation.

After the utility model end of job, the protector of the turned to sealing gasket on the trigger (14) rotation is peaked on the union (screwed)bonnet (UB (12), eliminate, prolong the service life of sealing gasket by the external force that thimble (13) is delivered on the sealing gasket (20).

The utility model adopts engineering plastics, in conjunction with carbon metal material in a small amount of, and the intensity height, easy to process, overall appearance, operation is light and handy, and is easy to maintenance, dependable performance, economy and durability.Because the utility model can directly inject nutrient the root of crop, so nutrient easily is absorbed, cuts the waste, and reduces cost, and helps improving the soil and reducing atmospheric pollution, save labor, be the good tool of peasant's cost-saving synergistic.
