Abstract

The utility model relates to a tree trunk injector, which belongs to the technical field of mechanical plant protection. The tree trunk injector is mainly used for preventing and killing insect pests on trees and can also be used for injecting liquid fertilizer or nutrient solution to the trees. The tree trunk injector is mainly composed of a machine body, an injection head with self-tapped threads, a driving gear, a driven gear, a ratchet wrench, a reversing valve for a handle, an injection wrench, a holding handle, an injection cavity, an oil cavity, a piston and travel delimiting screw nails. The utility model is mainly characterized in that a power source is not needed. As long as the ratchet wrench is rotated, the injection head is driven by the driven wheel to be rotated into the body of a trunk via the driving wheel; the piston is pushed by pressure oil to inject liquid medicine. The utility model has the advantages of reasonable structure, light weight, low labour intensity, convenient use and high efficiency. In one hour, 100 trees can be injected for 200 times.

Description

Tree trunk injector

The utility model relates to the equipment for plant protection field, and it is mainly used in control trees damage by disease and insect, also can be used for tree injection liquid fertilizer or nutrient solution.

At present, the control of trees damage by disease and insect, common method is the foliage spray agricultural chemicals.This method waste water resource and agricultural chemicals, control efficiency is relatively poor, and especially to the damage by disease and insect of trunk, control efficiency is poorer, and contaminated environment.Another kind method is to adopt the trunk coating, and its effect is not very good yet, and is difficult to realize mechanization, and productivity ratio is lower.

Advanced method is to adopt the trunk injection machine, agricultural chemicals is injected in the trunk body, show according to the data searching after Patent Office of the People's Republic of China's retrieval, the trunk injection machine that existing patent provides, roughly there are following two kinds: the trunk injector that (1) Chinese patent 91210452X provides, thrust trunk with syringe needle during operation ..., through test, with diameter is that the conical injection head of 5mm is pressed into camphor tree and needs the power of 200kg just can finish approximately in doing, and this is that manual operations is inefficient; (2) the trunk injection machine that provides of United States Patent (USP) 4176495 and 3832803 is to utilize power (as put-put or electromotor, injection head is entered in the trunk body, this has increased complexity to injector.Seldom dynamic source in China forest zone or the orchard, it is essential to increase engine, certainly will cause the weight of these facility to increase like this, and labour intensity improves, even might cause fire.

The purpose of this utility model provides a kind of power source and low ratchet spanner formula injector of labour intensity of not needing.

The purpose of this utility model is achieved in that adorns a ratchet spanner on driving gear; Shake this spanner and drive driving wheel, thereby enter fast in the trunk body by the rotation of driven pulley drive injection head; Utilize pressure oil to promote piston, finish soup effectively and inject action.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the utility model structure chart; Fig. 2 is the injection head cutaway view; Fig. 3 (A-A) is a medicine chamber cutaway view; Fig. 4 (B-B) is gear and needle stand cutaway view.

Concrete structure of the present utility model:

Partly formed by mechanical part, mechanical driving part and hydraulic drive.

As shown in Figure 1, this injector comprises: the rear and front end is that helicitic texture, inside are the body 16 of circular hole, and its front end (being the left end of Fig. 1) is connected with injection head 1, and the rear end is connected with holder handle 7; Injection head 1 is made up of syringe needle 21 and needle stand 22, syringe needle 21 front end outer surfaces are tapping screw thread, interior is injection orifice, and a leak-stopping is housed with steel ball 23 and spring 24, needle stand 22 is hollow multidiameter structure, is flexibly connected by nut 17 and machine body 16, and medicine chamber 4 is fixed a medicine absorbing tube joint 19 and medicine absorbing tube 20 behind, (shown in the A-A cutaway view) syringe needle 21 and needle stand 22 be by thread connection, and injection head 1 is by screw 18 travelling gear 2 that is fixedly connected; The upper side of body 16 has one to protrude axle 5, and driving gear 3 is housed above, and driving gear 3 and driven gear 2 and empty set are on body 16 rear end hollow shafts, near the gear 10 that holds in the palm handle 7 front end faces be meshed (10 balanced actions of gear); Ratchet spanner 6 fixedly is equipped with in driving gear 3 tops; The downside of body 16 fixedly is equipped with the handle 13 that contains reversal valve, and handle 13 left surfaces are equipped with injection spanner 14, and its top and body 16 downsides are hinged, and the interior reversal valve core bar of another fulcrum and handle 13 15 is hinged. Body 16 inner chambers are medicine chamber 4 and oil pocket 11, and the piston 12 that injection is arranged between a medicine absorbing tube joint 19 and medicine absorbing tube 20, two chambeies is fixed in medicine chamber 4 behind, and the upper cover of piston rod of piston 12 has spring 9, are a stroke limiting screw 8 behind the piston rod.

The course of work of the present utility model is such:

(one) holds handle 13, and holder handle 7 withstands in chest (abdomen) portion, with the moving ratchet spanner 6 of another palm, drives injection head 1 by

travelling gear

3,2 and rotates into the tree body then; At this time again by injection spanner 14, pressure oil enters oil pocket 11 by the reversal valve in the handle 13, promotes piston 12, and soup is injected the tree body through injection head 2.Injection finishes, and unclamps injection wrench 14, piston 12 and return original position under the effect of spring 9, and soup enters medicine chamber 4 through medicine absorbing tube 20, medicine absorbing tube joint 19, is in the SBR of injection next time.Adjust ratchet spanner 6 and pull it, make injection head 1 reverse rotation withdraw from trunk, finish the inferior injection process in a hole by travelling gear 3,2.Regulating piston stroke limit screw 8, the stroke of control piston 12, thereby the adjusting and the control of realization injection volume.

Embodiment:

Injection head 1 is made up of syringe needle 21 and needle stand 22 two parts, and syringe needle 21 is a hollow tapping screw thread structure, and needle stand 22 is a hollow multidiameter structure.Needle stand 22 flexibly connects with body 16 by attaching nut 17, and syringe needle 21 and needle stand 22 are by thread connection, and syringe needle 21 is fixedlyed connected with gear 2 by screw 18.During assembling, earlier leak-stopping is put into injection head 1 front end with spring 24, put into steel ball 23 again, gear 2 is enclosed within on the axle of needle stand 22, (shown in the B-B cutaway view) screws in the end of thread of needle stand 22 in the female end of syringe needle 21 then, and withstand steel ball 23, and syringe needle 21 is fixedlyed connected with gear 2 usefulness screws or alternate manner.Sealing place of all need all add sealing gasket.
