Description

TECHNICAL FIELD

[0001] The utility model belongs to the agricultural planting technical field, and particularly relates to a plant injector. BACKGROUND

[0002] Various growth solutions often need to be injected into the trunk during the growth of plants to enhance the immunity of plants and prevent and treat diseases and pests. Although the existing injectors can be used, they are inconvenient to use and have poor effects. Therefore, a special injector needs to be developed to meet the injection requirement of plant growth solutions. SUMMARY

[0003] The utility model discloses a plant injector to meet the requirement of high-efficiency injection of growth solutions to the trunk of plants.

[0004] The technical scheme of the utility model is implemented as follows: a plant injector, comprising an upper shell and a lower shell, the upper shell and the lower shell are connected into an integrated whole, an inner cavity is formed, a piston is arranged in the cavity, the piston is provided with a spring, one end of the piston extends out of the upper shell and is connected with a handle.

[0005] Preferably, the upper shell is provided with a clamping groove, the lower shell is provided with a buckle, and the upper shell and the lower shell are connected into an integrated whole through the buckle and the clamping groove.

[0006] Further, the injection head of the lower shell is provided with a thread.

[0007] Preferably, the extending end of the piston is provided with a sliding groove, the sliding groove is in interference fit with the handle, so that the handle and the piston are connected firmly and can be disassembled.

[0008] The utility model has the advantages of:

[0009] 1. The spring is arranged to automatically complete injection;

[0010] 2. The upper shell and the lower shell are detachably connected, and the handle and the piston are detachably connected, so that the assembly and maintenance of the injector are facilitated;

[0011] 3. The thread arranged on the injection head enables the injection head to be drilled into the hole of the trunk when injection, the whole injector is connected with the trunk into an integrated whole, and the injection process is automatically completed;

[0012] 4. The utility model enables the injection of plant growth solutions to be convenient and efficient. BRIEF DESCRIPTION OF DRAWINGS

[0017] The technical scheme of the utility model will be described clearly and completely in combination with the embodiments, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0018] As Figures 1 to 3 shown, the plant injector includes an upper shell 1 and a lower shell 2, the upper shell 1 is provided with two clamping grooves 11, the lower shell 2 is provided with two buckles 22, the upper shell 1 and the lower shell 2 are connected into an integral whole through the buckles 22 and the clamping grooves 11, an inner cavity is formed, a piston 3 is arranged in the cavity, the piston 3 is sleeved with a spring 4, one end of the piston 3 extends out of the upper shell 1 and is connected with a handle 5, the extending end of the piston 3 is provided with a sliding slot 31, the sliding slot 31 is interference-fitted with the handle 5, so that the handle 5 is connected firmly with the piston 3 and can be disassembled, and the injection head of the lower shell 2 is provided with a thread 21.

[0019] Working process and principle:

[0020] When assembling, the spring 4 is sleeved into the piston 3, then is placed into the upper shell 1, the sliding slot 31 end of the piston 3 extends out of the upper shell 1, the handle 5 is installed into the sliding slot 31, the lower shell 2 is sleeved into the other end of the piston 3 and is connected into an integral whole with the upper shell 1.

[0021] When using, the handle 5 is pulled to suck the growth liquid into the cavity formed by the upper and lower shells, at this time, the spring 4 is compressed, a hole is punched on the plant trunk, the injection head is drilled into the hole, at this time, the thread 21 is equivalent to a self-tapping screw, so that the injector is connected firmly with the trunk, both hands are released, the piston 3 is lowered under the action of the spring to inject the growth liquid into the trunk.

[0022] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
