Description

Self-press fertilizer-applicating gun

The present invention relates to the liquid fertilizer deep applicator tool in a kind of agricultural machinery.

The vast rural area of China mainly is the facial fertilising of soil to the fertilizing methods 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 object of the present invention is to provide a kind of self-press fertilizer-applicating gun, it is a kind ofly liquid fertilizer or agricultural chemicals can be expelled to crop root part quantitatively, the depthkeeping degree, the saving of labor, economizes fertilizer, water-saving, can be widely used in the requirement of crops deep placement chemical fertilizer and agricultural chemicals.

Technical scheme of the present invention realizes as follows: dish, water intake ball valve, water outlet ball valve etc. are formed deeply by handgrip, guide rod, guide rod spring, sliding sleeve, stopper rod, leather cup, sleeve, inserted link, limit in the present invention.Two guide rods and sliding sleeve are separately fixed on the handgrip, have chute, stopper rod to be contained in the sliding sleeve and by lateral pin on the sliding sleeve and are connected with sliding sleeve in chute, and stopper rod can slide up and down along chute in sliding sleeve; Several pin-and-holes are arranged, for the adjusting plug throw of lever after the split pin of packing on the stopper rod; Sleeve becomes an integral body with leader casing and water intaking valve system, the inner chamber of water inlet valve body communicates with barrel bore, water supply connector is equipped with in inner chamber bottom at the water inlet valve body, the end face of water supply connector is embedded with inlet valve, water intake ball valve is equipped with at inner chamber middle part at the water inlet valve body, muscle is arranged at the top at the water intaking valve intracoelomic cavity, block its path when preventing that water intake ball valve is up, the lower end of water supply connector is communicated with water tank through water inlet pipe, leather cup is housed in the sleeve, when leather cup is moved up and down in sleeve by the stopper rod drive, can makes and produce suction and pressure in the sleeve, inserted link is equipped with in the bottom of sleeve, the inner chamber of inserted link communicates with the inner chamber of sleeve, and the dark dish of limit is housed on the inserted link, and the dark dish of limit can be fixed on arbitrarily on the inserted link by lock-screw, flowing water Valve is equipped with in the bottom of inserted link, the water outlet ball valve, outlet valve spring and plug have injection orifice on the plug.

Advantage of the present invention is as follows:

The present invention inserts in the process of soil and dial-out soil at inserted link, can finish a working cycles of water spray and suction automatically, thereby improve operating efficiency greatly; With split pin control stopper rod stroke, can accurately calibrated shot; Outlet valve spring and water outlet ball valve are housed in the bottom of inserted link, can effectively prevent the liquid water clock.

With reference to accompanying drawing, the invention will be further described, in Figure of description, the top of two guide rods 24 and sliding sleeve 16 is fixing with handgrip 19 with screw 20, can slide in two leader casings 10 respectively in the bottom of two guide rods 24, between leader casing 10 and handgrip 19, guide rod spring 23 is housed, sleeve 11 and two leader casings 10 and the valve body 9 of intaking are made an integral body, the inner chamber of water inlet valve body 9 communicates with the inner chamber of sleeve 11, on water inlet valve body 9, water supply connector 6 and water intake ball valve are housed, water intake ball valve 8 is in the inner chamber energy easy on and off activity of water inlet valve body 9, water intake ball valve 8 be up to certain apart from the time have muscle 25 to block, because the slit is arranged around between muscle 25 and the water intake ball valve 8, the inner chamber of the valve body 9 of intaking remains path between the inner chamber of sleeve 11, and water intake ball valve 8 can seal inlet valve 7 when descending.In the bottom of sleeve 11 inserted link 26 is housed, the inner chamber of inserted link 26 communicates with the inner chamber of sleeve 11, plug 1, outlet valve spring 2, water outlet ball valve 3 and flowing water Valve 4 are equipped with in the bottom of inserted link 26, when the inner chamber of sleeve 11 did not produce big pressure, water outlet ball valve 3 was in the state of closing flowing water Valve 4 under the pressure of outlet valve spring 2.The other end that is installed in the water inlet pipe 5 in the water supply connector 6 is connected with water tank.

Before formal operation, handgrip 19 is pressed downwards for several times, the air in the sleeve 11 is discharged, allow liquid be full of in the sleeve 11.During operation, two hold handgrip 19, allow inserted link 26 aim at by fertilising soil, with the hands press handgrip 19 then, the bottom of inserted link 26 is inserted in the soil by plug 1, when the dark dish 28 of soil surface and limit contacts, inserted link 26 has stopped descending, handgrip 19 compression guide rod springs 23 continue descending, when handgrip 19 goes downwards to lateral pin 17 and contacts with the upper limb of chute 18, stopper rod 14 is pushed descending, it is descending in the direction of arrows to drive leather cup 13 simultaneously, and at this moment because inlet valve 7 has been sealed in the deadweight of water intake ball valve 8, the liquid in the sleeve 11 is just through inserted link 26 compression outlet valve springs 2, push water outlet ball valve 3 open, spray in the soil in the direction of arrows through injection orifice 29, when the split pin 15 on stopper rod 14 contacted with sleeve nut 22, the process of first injecting fluid stopped.When two hands loosen handgrip 19 and extract inserted link from soil, handgrip 19 moves up under the promotion of guide rod spring 23, when sliding sleeve 16 moves on to lateral pin 17 on handgrip 19 when contacting with the lower edge of chute 18, stopper rod 14 beginnings are up, because leather cup 13 usefulness acorn nuts 12 are tightened on the stopper rod 14, so leather cup 13 is also and then up, the lower lumen of sleeve 11 produces negative pressure, water outlet ball valve 3 has been closed flowing water Valve 4 under the promotion of outlet valve spring 2, at this moment, liquid in the water tank is through water inlet pipe 5, water supply connector 6, push water intake ball valve 8 open and enter the inner chamber of sleeve 11, when moving on to when contact the water absorption course termination on the leather cup 13 with sleeve nut 22 through the inner chamber of water inlet valve body 9.Once more inserted link 26 is inserted in another fertilising soil, press handgrip 19, carry out second course of work, so move in circles.

According to the condition and the fertilising requirement of fertilising soil, the present invention can do the adjusting of following aspect:

1, the adjusting of fertilising dosage: several pin-and-holes 21 are arranged at the middle part of stopper rod 14, if split pin 15 is penetrated in sleeve nut 22 pin-and-hole 21 far away, fertilising dosage becomes big, otherwise fertilising dosage then diminishes.

2, injecting fluid depth adjustment: unscrew the lock-screw 27 on the dark dish 28 of limit,, tighten lock-screw 27 again, can reach the purpose of the restriction injecting fluid degree of depth with limitting dark dish 28 to move on to the place of desired depth.
