DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1: Reference Figure 1-4 An injection fertilization device includes a shell 4, a water outlet is connected to the lower end of the shell 4, an inlet pipe 7 is connected to the shell 4, a connecting cover 1 is threadedly connected to the inlet pipe 7, and liquid fertilizer is injected from the inlet pipe 7.

[0020] An abutment column 15 is abutted in the water outlet hole, one end of the abutment column 15 is fixedly connected with a pointed head 16, and the other end is fixedly connected with a moving part 14, the pointed head 16 plays a role of breaking the soil, the diameter of the moving part 14 is smaller than the diameter of the abutment column 15, and the moving part 14 is fixedly connected with a connecting rod 6, and the connecting rod 6 is limited by a limiting mechanism, and the limiting mechanism includes a supporting ring 12, and the supporting ring 12 is fixedly connected to the shell 4, and a supporting block 13 is fixedly connected to the connecting rod 6, and the supporting block 13 is located below the supporting ring 12, and the connecting rod 6 passes through the supporting ring 12. When the device is inserted into the soil, the supporting block 13 abuts against the supporting ring 12, which plays a role of limiting the connecting rod 6, so that the abutment column 15 is located in the water outlet hole in the shell 4, preventing the entry of soil during insertion and causing blockage. When injecting, the connecting rod 6 is driven downward by the moving mechanism, so that the moving part 14 enters the water outlet hole, and a gap is generated between the water outlet hole, so that fertilizer flows in for fertilization.

[0021] The connecting rod 6 is moved by the moving mechanism, a sealing plug 9 is fixedly connected to the connecting rod 6, a sealing ring 10 is fixedly connected to the inner wall of the shell 4, a connecting cover 11 is connected to the sealing ring 10, the connecting cover 11 is fixedly connected to the shell 4, the sealing plug 9 can abut against the sealing ring 10, and the upper end of the sealing plug 9 and the shell 4 form a liquid storage chamber. When the moving mechanism moves, the sealing plug 9 moves downward, which will make the sealing plug 9 enter the connecting cover 11 and break away from the abutment with the sealing ring 10, so that the fertilizer flows down and enters the underground from the water outlet.

[0022] The moving mechanism includes a fixed part 17, which is fixedly connected to a connecting rod 6. The connecting rod 6 passes through the shell 4 and is connected to the shell 4 through a sealing ring. A telescopic rod 5 is fixedly connected to the fixed part 17, and the telescopic rod 5 is fixedly connected to the shell 4. The connecting rod 6 is driven to move downward by contraction of the telescopic rod 5, and the connecting rod 6 is reset by extension of the telescopic rod 5. The telescopic rod 5 is an electric telescopic rod. A battery 8 is installed on the shell 4, and the battery 8 is connected to the telescopic rod 5 through a wire.

[0023] When in use, the device is first inserted into the soil to the required depth, and then the telescopic rod 5 is retracted, driving the connecting rod 6 to move downward, so that the movable part 14 enters the water outlet, and at the same time the sealing plug 9 moves downward, which will make the sealing plug 9 enter the connecting cover 11 and break away from the abutment with the sealing ring 10, so that the fertilizer flows down and enters the underground from the water outlet for fertilization.

[0024] Example 2: Reference Figure 1-4 As another preferred embodiment of the utility model, on the basis of embodiment 1, a pedal 2 is fixedly connected to the shell 4, and the pedal 2 is used to facilitate stepping, and the shell 4 is inserted into the ground.

[0025] Example 3: Reference Figure 1 As another preferred embodiment of the utility model, on the basis of embodiment 1, scale lines are provided on the shell 4, and the scale lines are designed to serve as a reference. Since the depths of the roots of different plants are different, the insertion depth is controlled by using scale lines for reference.

[0026] Example 4: Reference Figure 1-4 As another preferred embodiment of the utility model, on the basis of embodiment 1, a grasping rod 3 is fixedly connected to the shell 4, and the grasping rod 3 serves to facilitate grasping so as to pull the shell 4 out of the soil.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
