Description

Technical Field

[0001] The invention relates to the technical field of fruit tree drug injection, and in particular to a fruit tree disease and insect pest control drilling and drug injection device. Background Art

[0002] For the prevention and control of pests on fruit tree trunks, sprayers are generally used to spray the trunks with pesticides. Since the larvae and eggs of pests are hidden in the wood or under the cortex, the pesticide solution is not easy to take effect and the control effect is very poor. In addition, a large amount of pesticides will remain on the fruits when spraying, which is harmful to human health. In addition, the pesticide solution is seriously wasted, polluting a large area and affecting the ecological environment. Therefore, under conditions that are not suitable for spraying, holes can be drilled in the trunks, and then the pesticide solution can be injected into the holes, so as to achieve the purpose of preventing and controlling pests and diseases and protecting trees.

[0003] For example, the patent with announcement number CN211020152U discloses a rapid drilling and injection device for controlling pests and diseases of fruit trees. Although it can drill holes and inject drugs into fruit trees, the drilling and injection functions are not integrated, resulting in the need for workers to remove the drilling equipment and inject drugs after drilling, and the device does not have the function of sealing the tree holes, causing the drug solution and water of the fruit trees to evaporate after drilling, thus reducing the effect of use. Therefore, it is urgent to design a drilling and injection device for controlling pests and diseases of fruit trees. Summary of the invention

[0045] Please see attached Figure 1 -Attached Figure 7 In a preferred embodiment, the top of the cylinder 1 is open, and the top of the cylinder 1 is connected to a first end cover 4 by a threaded rotation. A through groove is opened on the side of the first end cover 4, and the inside of the through groove is connected to a second end cover 5 by a threaded rotation.

[0046] The working principle of the present invention is as follows: first, the barrel 1 is fixed on the fruit tree that needs to be punched and injected with medicine by the clamp 2. It should be noted that the clamp 2 is a mature existing technology, and this document does not make any improvement to it, so it will not be described in detail;

[0047] When it is necessary to drill holes in the fruit trees, the first motor 11 is started to drive the pulley 10 and the belt 9 to rotate 120 degrees. The rotation of the pulley 10 drives the fixed disk 6 to rotate. The rotation of the fixed disk 6 drives the fixed rod 26, the first barrel 7 and the second barrel 8 to rotate. The rotation of the fixed rod 26 drives the turntable 12 to rotate. The rotation of the turntable 12 drives the sleeve 13 and the second spring rod 22 to rotate with the center of the turntable 12 as the center of the circle. The rotation of the second spring rod 22 drives the components thereon to rotate together, so that the push-pull plate 20 is placed inside the corresponding U-shaped block 16. Then the electric telescopic rod 19 is started to drive the push-pull plate 20 to move horizontally. The movement of the push-pull plate 20 drives the U-shaped block 16 and the second L-shaped plate 21 to move. The movement of the second L-shaped plate 21 drives the L-shaped frame 24 to move. The movement of the L-shaped frame 24 drives the drill rod 18 to move out of the barrel 1 through the through slot, and the second motor 25 is started synchronously. The hollow tube 23 is driven to rotate, and the rotation of the hollow tube 23 drives the drill rod 18 and the first bevel gear 28 to rotate, and the rotation of the first bevel gear 28 drives the second bevel gear 29 to rotate, and the rotation of the second bevel gear 29 drives the disc 30 to rotate, and the rotation of the disc 30 drives the third spring rod 31 to move back and forth, and the movement of the third spring rod 31 drives the sleeve ring 27 to move back and forth, and the movement of the sleeve ring 27 drives the drill rod 18 to move back and forth, so that the drill rod 18 will follow the sleeve ring 27 to do horizontal reciprocating movement when following the second L-shaped plate 21 to move horizontally, and further, the drill rod 18 can be telescoped back and forth in the hole when drilling holes in the fruit tree, so as to avoid the situation that the drill rod 18 is stuck and cannot rotate, and at the same time, the waste generated during the drilling can be discharged from the hole, and when the drilling of the fruit tree is completed, the drill rod 18 is reset inside the cylinder 1 through the electric telescopic rod 19;

[0048] Then, the first motor 11 is started again to drive the turntable 12 to rotate 120 degrees again, so that the push-pull plate 20 can be placed inside the corresponding U-shaped block 16 again, and the electric telescopic rod 19 works again to drive the corresponding injection tube 14 to move through the U-shaped block 16. When the injection tube 14 enters the hole, the corresponding liquid pump is started, and the liquid in the first barrel 7 can be further injected into the hole through the sleeve 13 and the injection tube 14. After the injection is completed, the corresponding injection tube 14 is reset by entering the cylinder 1 through the electric telescopic rod 19;

[0049] Finally, the first motor 11 is started again to drive the turntable 12 to rotate 120 degrees again, so that the push-pull plate 20 can be placed inside the corresponding U-shaped block 16, and the electric telescopic rod 19 works again to drive the corresponding injection pipe 14 to move through the U-shaped block 16. When the injection pipe 14 enters the hole, the corresponding liquid pump is started, and the resin plugging agent inside the second barrel 8 can be further injected into the hole through the sleeve 13 and the injection pipe 14 to plug the hole. After the plugging is completed, the corresponding injection pipe 14 is reset by entering the cylinder 1 through the electric telescopic rod 19;

[0050] In summary, the drilling, injection and plugging of fruit trees can be completed, which is convenient and quick, thereby improving the use effect of the equipment.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
