Abstract

The utility model relates to a liquid fertilizer fertilizing machine. A sliding tube head (16) is sheathed on a tube head, a push-up plate is fixed on the sliding tube head, and the middle is supported by a push rod sleeve (9); a cavity body formed by the inner side of a push rod and a push-down plate and arranged between a push plate and the push rod sleeve is provided with a return spring, the spring is sheathed on a needle rod exended to the inner part of the cavity, and a pressure regulating ring (8) can regulate the slack of the spring. The center of a casing (11) is provided with a rubber washer, and a mid hole of the washer is communicated with a liquid through hole (23) at the center of the casing and a hole canal of the needle rod (2). The utility model has the functions of automatic infusion and automatic return, and can continuously work; work efficiency is enhanced, labor strength is lightened, and the utility model can be used for fertilization and drip irrigation.

Description

The liquid fertilization device

The utility model relates to sprinkling machine, specifically is meant a kind of liquid fertilization device.

High-efficiency agriculture and water-saving irrigation are the new models of developing agricultural.China is as a developing power, and resource occupancy volume per person also is one of country than lack of water seldom.With the fertilising of watering of common mist sprinkler tool, waste quite big.Crop root is applied fertilizer or waters and can improve fertilizer efficiency or using water wisely greatly.But at present too low to the agriculture devices work efficient of crop root fertilizing, watering, this is owing to its design defect causes.A kind of root liquid fertilization device is for example arranged, roughly as a big injector for medical purpose, need bimanualness, one pushes away one draws and liquid could be injected crop root, not handy, so popularity rate is not high.

But the liquid fertilization device that the purpose of this utility model provides a kind of automatic infusion and resets with handled easily, improves work efficiency.

Described liquid fertilization device comprises syringe needle, the shank that is connected as a single entity with syringe needle, push rod, each parts of tube head, tube head and shank, syringe needle are divided into two-section, it is characterized in that: be with a slip pipe head (16) on the tube head of described fertilizer applicator (20), be fixed with push pedal (14) on it, last push pedal is connected with following push pedal (4) by push rod (6), and the centre provides supporting by push rod (9); Following push pedal central authorities are fixed with shank (2) and syringe needle (1), between following push pedal (4) and pushing rod sleeve (9), in the cavity of the inboard and following push pedal formation of push rod (6), a return spring (5) is housed, on the shank (2) of this spring housing in stretching to the chamber, by pressure regulation circle (8) locking and adjusting.One compression cap (15) is housed on the slip pipe head (16), and slip pipe head base (22) is put down and atresia, and the side has lateral opening (21); Put in housing (11) chamber that has lining (12); Housing (11) tail end bottom center is embedded with rubber washer (10) porose in the middle of, and the liquid-through hole (23) of the mesopore of rubber washer and housing central authorities and the liquid-through hole of shank (2) link.

Described fertilizer applicator tube head and sprayer woven hose are linked, after the pressurization, liquid can be annotated to crop root from the pin hole of syringe needle side, lift fertilizer applicator, under the effect of return spring, push rod, push plate device are promptly sealed the transfusion path automatically, so can work continuously, improve work efficiency greatly, alleviated labour intensity.

Fig. 1 is the utility model structure principle chart.

Fig. 2 is the utility model connection diagram.

Among the figure: push pedal under 1-syringe needle, 2-shank, 3-flat head screw, the 4-, 5-return spring, 6-push rod, 7-pressure regulation circle filler are contained, and 8-pressure regulation circle, 9-pushing rod sleeve, 10-rubber washer, 11-housing, 12-lining, the culvert of 13-filler, the last push pedal of 14-, 15-compression cap, 16-slip pipe head, 17-handle, 18-cramp bar, 19-fixing collar, 20-feed pipe, 21-slip pipe be hole, 22-slip pipe head base, 23-housing central authorities liquid-through hole in front.

Handle (17) and sprayer woven hose are linked, and liquid enters feed pipe (20).The user inserts soil with the shank (2) of fertilizer applicator, when syringe needle (1) arrives certain depth, push pedal under the soil jack-up (4) spring (5) pressurized shrinks, by push pedal (14) in push rod (6) picking-up, lift slip pipe head (16) certain altitude, the highly pressurised liquid that enters slip pipe head (16) this moment is poured in the liquid-through hole (23) at housing (11) center from lateral opening (21) at the pipe end, behind the mesopore by rubber hole pad (10), injects soil through shank (2) duct by the lateral opening brute force of syringe needle (1).When carrying fertilizer applicator on the user, following push pedal (4) is resetted by the spring pushing, depress slip pipe head (16) by the push pedal (14) that countersunk head screw (3) is fixing, the pipe base of atresia compresses the rubber hole pad (10) at housing (11) center to the downslide tube head so that it is flat, and the path of blocking-up liquid so just performs next operation time time preparation.The effect of compression cap (15) is that the asbestos yarn that will speckle with lubricating oil compresses the above space of lining (12), stops outside the fluid seepage housing.Pressure regulation circle (8) is used to adjust the pressure of spring.

Claims

1, a kind of liquid fertilization device, comprise syringe needle, shank, push rod, each parts of tube head, tube head and shank (20) and syringe needle are divided into two-section, it is characterized in that: be with a slip pipe head (16) on the tube head of described fertilizer applicator, be fixed with push pedal (14) on it, last push pedal connects with following push pedal (4) by push rod (6), and the centre provides supporting by push rod (9); Following push pedal central authorities are fixed with shank (2) and syringe needle (1), pushing away between flat board (4) and the pushing rod sleeve (9) down, this spring housing of a return spring (5) is housed in the cavity that push rod (6) is inboard to be formed with following push pedal is stretching on the shank (2) in the chamber, by pressure regulation circle (8) locking and adjusting.
