Description

Self-press fertilizer-applicating gun

This is suitable for the novel liquid fertilizer deep applicator tool that relates in a kind of agricultural machinery.

The vast rural area of China mainly is that face is executed to the fertilizing method of crops at present, and this not only causes a large amount of wastes of fertilizer, and take a lot of work, water wasting, because of weather can't apply fertilizer when overcast and rainy or arid, influence the growth of crops.

The purpose of this utility model is to provide a kind of self-press fertilizer-applicating gun, it be a kind of can with the fertilizer of liquid or agricultural chemicals quantitatively, the depthkeeping degree be expelled to crop root part, the saving of labor, economize fertile, water-saving, can be widely used in the requirement of crops deep placement chemical fertilizer and agricultural chemicals.

The technical solution of the utility model realizes as follows: the utility model by handgrip, movable handgrip, guide rod, spring, leather cup, stopper rod, sleeve, water intaking valve, injection rod, limit coil deeply, outlet valve etc. forms.Guide rod is welded on the sleeve, and spring is housed on the guide rod, and lower end of the guide rod is drilled with pin-and-hole, is convenient to the pressure of regulating spring; Grip cover and can slide up and down along guide rod on guide rod, is welded with sliding sleeve in the middle of the handgrip, and chute is arranged on the sliding sleeve, and stopper rod is contained in the sliding sleeve, and is connected with sliding sleeve in chute by lateral pin, and stopper rod can be free to slide along chute in sliding sleeve; Several jump ring grooves are arranged, for the adjusting plug throw of lever behind the jump ring of packing on the stopper rod; Movable grip cover is on handgrip, and fat freely rotates along handgrip, is welded with band iron on the movable handgrip, and during rotation activity handgrip, band iron can cover or open two guide rod holes on the handgrip; Leather cup in the sleeve can make the bottom of barrel bore produce vacuum or pressure when stopper rod drives up and down; Sleeve below is welded on the injection rod, and water intaking valve is equipped with on the top of injection rod, and water intaking valve is connected with water tank through water pipe, and the middle part of injection rod is equipped with limit and is coiled deeply, limits fixed distance that dark dish can be as required on injection rod, and outlet valve and injection orifice are arranged at the bottom of injection rod.

It is as follows that this is suitable for novel advantage:

This is suitable for novel in a process of injection rod insertion soil and dial-out soil, can finish a working cycles of water spray and suction automatically, thereby improved operating efficiency greatly, can accurately calibrated shot with jump ring control stopper rod stroke, utilization activity handgrip can make injection rod in big resistivity soil and normal operation in the super deeper injection, in the bottom of injection rod outlet valve spring and outlet valve are housed, can effectively prevent the water clock of liquid.

With reference to accompanying drawing embodiment, this is suitable for novel being described further, in Figure of description, the other end of water inlet pipe (25) is connected with water tank, before formal operation, handgrip (17) is pressed downwards for several times, air in the sleeve (6) is discharged, allow liquid be full of in the sleeve (6).During operation, two hold movable handgrip (18), allow injection rod (5) aim at by fertilising soil, if the little or fertilization depth of soil specific resistance is in 20CM the time, then the inclined to one side iron (20) with movable handgrip (18) turns to the place that does not cover guide rod hole (21), with the hands press movable handgrip (18) then downwards, the bottom of injection rod (5) is inserted in the soil, when soil surface and the dark dish of limit (4) when contacting, injection rod (5) has stopped descending, handgrip (17) compression spring (22) continues descending, when handgrip (17) goes downwards to lateral pin (16) and contacts with the upper limb of chute (15), stopper rod (10) is pushed toward descending, and it is descending to drive leather cup (9) simultaneously, at this moment, liquid compression outlet valve spring (1) in the sleeve (6) is also pushed outlet valve (2) open, spray in the soil through injection orifice (3), the jump ring (12) on stopper rod (10) and socket cover (23) are when contacting, and the process of first injecting fluid stops.Two is openhanded when opening movable handgrip (18) and transfering to injection rod (5) from last earth, handgrip (17) moves up under the promotion of spring (22), when moving on to lateral pin (16) on the sliding sleeve (14) when contacting with the lower edge of chute (15), stopper rod (10) and leather cup (9) beginning are up, the lower lumen of sleeve (6) produces vacuum, outlet valve (2) is closed under the promotion of outlet valve spring (1), when external atmospheric pressure during greater than the pressure of water intaking valve spring (28), water intaking valve (26) is open, the liquid of water tank is through water inlet pipe (25), water inlet valve body (27), enter the inside of sleeve (6), move on on leather cup (9) and protect water jacket (24) when contacting, water absorption course stops.Again injection rod (5) is inserted in another soil that applied fertilizer, press movable handgrip (18), carry out second course of work, so move in circles.

According to the condition and the fertilising requirement of the soil that applied fertilizer, this is suitable for novel adjusting of making following aspect:

1, the adjusting of fertilising dosage: several jump ring grooves (13) are arranged at the middle part of stopper rod (10), if jump ring (12) is contained in from socket cover (23) jump ring groove (13) lining far away, fertilising dosage becomes big, otherwise fertilising dosage then diminishes, in the position of jump ring groove (13), can accurately control fertilising dosage according to jump ring (12).

2, the injection rod operating pressure is regulated; If soil specific resistance is big, then two split pins (11) can be inserted in the pin-and-hole (8) of two guide rods (7) top, to increase the operating pressure of two springs (22) to injection rod (5); If soil specific resistance is little, then two split pins (11) are inserted in the pin-and-hole (8) of two guide rods (7) below, to reduce the operating pressure of spring (22) to injection rod (5), by the operating pressure of regulating spring (22) to injection rod (5), when contacting soil to reach the dark dish of limit (4), injection orifice (3) begins to spray the purpose of liquid.

3, injecting fluid depth adjustment; Unscrew the lock-screw (29) on the dark dish of limit (4), will limit dark dish (4) to move on to the place of desired depth, tighten lock-screw (29) again, can reach the purpose of the restriction injecting fluid degree of depth.If the injecting fluid degree of depth requires when 20Cm is above, during operation movable handgrip (18) is turned to the place that band iron (20) covers guide rod hole (21), again toward pressing down movable handgrip (18), when the dark dish of limit (4) contact soil, rotation activity handgrip (18), allow band iron (20) expose two guide rod holes (21), press the descending operation of handgrip (17); When if the injecting fluid degree of depth requires in 20Cm, the pin (19) on also can dial-out activity handgrip (18) sheds movable handgrip (18) and carries out operation.
