Description

Self-press fertilizer-applicating gun

The utility model 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 purpose of this utility model is to provide a kind of self-press fertilizer-applicating gun, it be a kind of can with liquid fertilizer 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: form deeply by dish, water intake ball valve, water outlet ball valve etc. by handgrip, guide rod, guide rod spring, sliding sleeve, stopper rod, leather cup, sleeve, inserted link, limit for the utility model.Two guide rods and sliding sleeve are fixed on the handgrip with screw or rivet respectively, 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 utility model is as follows:

The utility model 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 utility model is described in further detail, in Figure of description, the top of two guide rods (24) and sliding sleeve (16) is fixing with screw (20) and handgrip (19), 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) is made an integral body with two leader casings (10) and water inlet valve body (9), 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 (8) 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) has muscle (25) to block when being up to certain distance, unlikely sealing water inlet valve body (9) inner chamber is to the path of sleeve (11) inner chamber, 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 internal organ 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 soil surface and the dark dish of limit (28) when contacting, inserted link (26) has stopped descending, handgrip (19) compression guide rod spring (23) continues 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, at this moment because inlet valve (7) has been sealed in the deadweight of water intake ball valve (8), liquid in the sleeve (11) is just through inserted link (26) compression outlet valve spring (2), push water outlet ball valve (3) open, spray in the soil in the direction of arrows through injection orifice (29), split pin (15) on stopper rod (14) and sleeve nut (22) are when contacting, and the process of first injecting fluid stops.Two is openhanded when opening handgrip (19) and extracting 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) beginning is up, because leather cup (13) is tightened on the stopper rod (14) with acorn nut (12), 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) enters sleeve (11) through the inner chamber of water inlet valve body (9) inner chamber open, move on on leather cup (13) and sleeve nut (22) when contacting, water absorption course stops.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 utility model can be done the adjusting of following aspect:

1, the adjusting of fertilising dosage: at the middle part of stopper rod (14) several pin-and-holes (21) are arranged, 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 of limit (28), will limit dark dish (28) to move on to the place of desired depth, tighten lock-screw (27) again, can reach the purpose of the restriction injecting fluid degree of depth.
