Description
The utility model relates to a kind of forestry operating apparatus, particularly a kind of syringe that injects soup or liquid fertilizer in the tree body.
Traditional trees deinsectization, fertilising adopts that blade face, trunk are sprayed insecticide, fertilizer or water, bury medicine or fertilizer at usage tree root, this deinsectization, fertilization mode, medicine, fertilizer are absorbed slower by trees on the one hand, be difficult for reaching higher valid density on the other hand, especially the insect that is drilled in the trees often do not had killing effect.In order to improve the effect that trees spray medicine fertilizer, people develop the various devices of directly giving tree injection soup or liquid fertilizer, a kind of syringe that utilizes spring soup to be injected fast the tree body through nook closing member from needle tubing is disclosed as Chinese patent 87203030, though this syringe speed is fast, but because of injection speed too fast, trees can't transient absorption, soup outflow when extracting entry needle, thereby effect is undesirable.Chinese patent 89220961.5 discloses a kind of tree injection machine, cylinder barrel, cylinder frame, check valve body, connecting rod, handle and woven hose and syringe needle that utilization is installed on the base inject soup or medicine fertilizer in the trees body, this injector can be controlled injection speed with handle, reducing soup flows out in the tree body, but this syringe construction complexity, volume is big, inconvenient maintenance.
The purpose of this utility model is to overcome the deficiencies in the prior art, and the tree injector of little, simple in structure, the easy to maintenance controlled injection speed of a kind of volume is provided.
The utility model is realized by following technical proposals:
Design a garden column type cylinder body, be provided with the piston rod that adapts with cylinder body in the cylinder body, there is an annular groove in the piston rod one end outside, be provided with the rubber washer that closely contacts with cylinder chamber in the groove, cylinder body lower end and capable being threaded of taper fluid mouth of being with hollow hole, the piston rod other end is connected with augering screw one end, and the augering screw other end is affixed by the center screw and the whirligig of cylinder cover, and the capable screw thread of cylinder cover and cylinder body is affixed.
Augering screw and being connected of piston rod can be to be inserted in fixedly connectedly, also can be provided with the screw of annular groove or symmetry on the augering screw of connecting portion or piston rod, and screwhole diameter makes the two movable connection less than recess width by bolt.
On the cylinder body lateral wall, be provided with a chute, be provided with the slide bar of band scale in the groove,, calculate the amount of soup or liquid fertilizer in order to measure the length of augering screw precession or back-out.
Inferior part of the cylinder block is established a feed tube, and the mouth of pipe is provided with non-return valve in the siphunculus mutually with cylinder chamber, is provided with non-return valve in the taper fluid mouth hollow hole.
Can not establish a pad at piston rod in case of necessity with the augering screw link, affixed with double-screw bolt or the screw established on nut or bolt and the piston rod.
Whirligig can be designed to handwheel or crank.
Taper fluid mouth outer wall is provided with screw thread.
Accompanying drawing and drawing explanation:
Accompanying drawing is a kind of concrete structure cutaway view of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in the figure, design a garden shape cylinder body (1), the most handy metal material.Design has the piston rod (2) that adapts with cylinder body in the cylinder body, the piston rod one end outside is provided with annular groove (3), groove width with greater than 0.5cm for well, being provided with the ring-shaped rubber packing ring that closely contacts with cylinder chamber or cup-shaped rubber washer (4) in the groove, can to set up double-screw bolt or screw that a pad (5) sets up with nut 6 or bolt and piston rod part at piston rod part in case of necessity affixed, leaks to increase anti-liquid.The cylinder body lower end is threaded with taper fluid mouth 9 row of band hollow hole, and the two can establish packing ring.For ease of advancing medicine and injection continuously continuously, can establish a feed tube (7) at inferior part of the cylinder block, the mouth of pipe one end communicates with cylinder chamber, the other end communicates with soup, be provided with non-return valve (8) in the pipe, in the hollow hole of taper fluid mouth, be provided with simultaneously non-return valve (10), the piston rod other end is connected with augering screw (13), connection can be fixedly connected, also can on the piston rod of connecting portion or augering screw, establish the screw of the dark 1-2mm of an annular with upper groove (11) or symmetry, screwhole diameter makes the two movable connection less than recessed width by bolt 12, should stay the space of 0.3-0.5mm at the bottom of bolt and the groove.So that during the augering screw turn, the piston body of rod seesaws.The other end of augering screw by with the capable cylinder cover that is threaded of cylinder body (14) on center screw affixed with handwheel or crank.
For ease of measuring liquid medicine injection, can be used on and establish a chute on the cylinder body lateral wall, be provided with the slide bar of band scale in the groove, can measure the screw rod degree of precession or back-out, calculate soup or liquid fertilizer amount.
Can be provided with screw thread at taper fluid mouth outer wall in case of necessity, so that combine closely with trees, leakage when preventing to inject.During assembling, elder generation is with the annular groove and annular or cup-shaped rubber blanket socket of piston rod one end, if piston rod part is provided with pad, pad is fixed in piston rod part by nut or bolt, cylinder cover is fixedlyed connected with cylinder body, end with augering screw connects by the symmetrical capable activity of bolt with the annular groove that piston rod is not established rubber blanket one end again, again with the augering screw that connects and piston rod from the inferior part of the cylinder block cylinder chamber of packing into, the augering screw upper end is affixed by cylinder cover center screw thread and whirligig, and the capable screw thread of taper fluid mouth and inferior part of the cylinder block is affixed.
During use, soup or liquid fertilizer container are connected with feed tube, whirligig is rotated the back-out augering screw, the non-return valve of liquid mouth is closed, form negative pressure in the cylinder body, soup or liquid fertilizer, then enter cylinder chamber, soup inhale good after, the fluid mouth is injected on trunk in advance in the hole of boring with hand drill, can utilize the screw thread precession on the fluid mouth outer wall in case of necessity, contact tightr like this with trunk, turn whirligig (direction is opposite with back-out) cuts out the non-return valve of feed tube, and the non-return valve of liquid outlet is opened, and soup or liquid fertilizer are entered in the tree body.If there is not feed tube, can adopt and fluid mouth (not being with non-return valve) is stretched into soup draw maybe will to go out mouth and back out, soup or liquid fertilizer are directly placed in the cylinder chamber, other methods of operating are identical.
The utility model volume is little as can be seen from said structure, and is in light weight, easy to maintenance, and can control the speed of liquid medicine injection or liquid fertilizer by control whirligig velocity of rotation, all absorbed by trees and can not leak outside to guarantee soup or liquid fertilizer.Augering screw of the present utility model in addition connects with groove is movable by the bolt that is symmetrically distributed with piston rod, and when the augering screw rotation advanced or withdraws from, piston rod and rubber washer seesawed, can not rotate, resistance when having reduced operation makes operation just flexible, and is convenient.
