DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1The utility model discloses a forest fertilization device, including a fertilizer main body 200, which includes an outer cylinder 210, and the outer cylinder 210 can be inserted into the soil; an inner rod 230, which is arranged in the outer cylinder 210 along the central axis direction of the outer cylinder 210, and a medicine storage space is formed between the inner rod 230 and the outer cylinder 210, and the medicine is located in the medicine storage space. A leakage hole 211 is arranged along the lower part of the outer cylinder 210 in the circumferential direction, so that the medicine in the medicine storage space can enter the soil from the leakage hole 211. The reason for setting the inner rod 230 is to occupy the internal space of the outer cylinder 210. Compared with the prior art in which the medicine is directly placed completely inside the hollow cylinder, this method can increase the diameter of the outer cylinder 210 under the condition of the same amount of medicine, thereby increasing the external surface area, and increasing the space occupied by the soil, thereby expanding the area occupied by the medicine after being discharged from the leakage hole 211. Therefore, the forest fertilization device provided by the embodiment of the utility model expands the fertilization area after being inserted into the soil once, thereby improving the fertilization efficiency and avoiding wasting liquid medicine.

[0024] Combination Figure 1 and Figure 2 As shown, in order to further expand the area of ​​the soil into which the liquid medicine enters after being discharged, a piston 240 is provided here, the piston 240 is provided at the upper end of the outer cylinder 210, and a middle hole for passing the inner rod 230 is provided in the middle of the piston 240, and a lifting mechanism for driving the piston 240 to rise and fall is provided on the outer cylinder 210, and the outer cylinder 210 is lowered to apply pressure to the liquid medicine in the medicine storage space, so as to extend the path of the liquid medicine after being sprayed out from the leakage hole 211, thereby expanding the area of ​​the liquid medicine spreading. Therefore, the fertilization area of ​​the forest fertilization device provided in this embodiment after a single insertion into the soil is further expanded, thereby further improving the fertilization efficiency, further avoiding the waste of liquid medicine, and the liquid medicine has better permeability in this state.

[0025] Combination Figure 3 and Figure 4 As shown, in order to facilitate the use of the present device, the forest fertilization device provided in this embodiment also includes a mobile vehicle 100. By pushing the mobile vehicle 100, the present device can be conveniently moved in the forest. In addition, the mobile vehicle 100 can be replaced with a remote-controlled vehicle, which is more convenient. A telescopic cylinder 300 is provided on the mobile vehicle 100. A lifting plate 310 is installed at the lower end of the telescopic rod of the telescopic cylinder 300. The lifting plate 310 is fixed to the outside of the circumference of the outer cylinder 210, so as to facilitate the telescopic cylinder 300 to drive the outer cylinder 210 to insert or pull out the soil.

[0026] Combination Figure 2 and Figure 5As shown, the lifting mechanism mentioned above includes an external thread, which is arranged on the outer surface of the content rod 230, a metal cylinder is installed in the middle hole of the piston 240, and the inner wall of the metal cylinder is provided with an internal thread, the external thread is adapted to the internal thread, and a rotating component 400 is installed on the lifting plate 310, and the rotating component 400 is used to drive the content rod 230 to rotate, so that a thread force is generated between the internal thread and the external thread to drive the piston 240 to rise and fall along the content rod 230. When the piston 240 moves downward, it can squeeze the medicine in the medicine storage space, so that the medicine has a certain initial velocity when it is discharged from the leakage hole 211, thereby increasing the path traveled by the medicine after being discharged, and the permeability of the medicine in this state is better.

[0027] Combination Figure 2 and Figure 5 As shown, in order to prevent the piston 240 from rotating with the content rod 230, the inner cavity of the outer cylinder 210 is a polygonal structure, and the outer wall of the piston 240 is a polygonal structure, so that the piston 240 is positioned in the circumferential direction to prevent the piston 240 from rotating and enable it to move only up and down.

[0028] Combination Figure 2 The rotating assembly 400 mentioned above includes a motor 410 installed above the lifting plate 310, a driving gear 420 fixed to the power output end of the motor 410, and a driven gear 430 fixed to the outer circumference of the upper end of the content rod 230. The driving gear 420 is meshed with the driven gear 430. When the motor 410 is working, the driving gear 420 can be driven to rotate. When the driving gear 420 rotates, the driven gear 430 can be driven to rotate, thereby realizing the rotation of the content rod 230.

[0029] Continue to refer to Figure 2 A liquid inlet hole 231 is opened in the middle of the upper end of the content rod 230, and liquid outlet holes 232 are opened on both sides of the content rod 230 near the upper end, so that the medicine can enter through the liquid inlet hole 231 and enter the medicine storage space from the liquid outlet hole 232.

[0030] Combination Figure 1 A pointed head 220 is fixed at the lower end of the outer cylinder 210 to reduce the resistance when the fertilizing body 200 is inserted into the soil and facilitate the insertion of the outer cylinder 210. Preferably, the upper end diameter of the pointed head 200 is larger than the diameter of the outer cylinder 210, so that the diameter of the hole inserted by the pointed head 200 in the soil is larger than the diameter of the outer cylinder 210, so that there is a gap between the outer cylinder 210 and the soil to avoid the leakage hole 211 caused by the upward movement of the piston 240 to suck in soil particles from the outside.

[0031] Combination Figure 3 and Figure 4As shown, a medicine liquid storage barrel 500 is provided on the mobile vehicle 100, and a medicine discharge pump 510 is installed at the lower side of the medicine liquid storage barrel 500. A medicine tube 520 is installed on the discharge pipe of the medicine discharge pump 510. The medicine tube 520 is used to insert or withdraw from the liquid inlet hole 231, so as to facilitate the injection or non-injection of medicine into the liquid inlet hole 231.

[0032] The mobile vehicle 100 in this embodiment includes a base 120 , a travel wheel 110 is arranged below the base 120 , a top seat 140 is installed above the base 120 via a column 130 , and the telescopic cylinder 300 is installed on the top seat 140 .

[0033] The working principle and use process of the utility model are as follows: when in use, the outer cylinder 210 is inserted into the soil through the telescopic cylinder 300, and then the medicine tube 520 is used to feed the medicine liquid into the liquid storage space through the liquid inlet hole 231 and the liquid outlet hole 232. When the motor 410 is working, it can drive the driving gear 420 to rotate, and when the driving gear 420 rotates, it can drive the driven gear 430 to rotate, and then realize the rotation of the content rod 230, so that a thread force is generated between the internal thread and the external thread, so as to drive the piston 240 to rise and fall along the content rod 230. When the piston 240 moves downward, it can squeeze the medicine liquid in the medicine storage space, so that the medicine liquid has a certain initial velocity when it is discharged from the leakage hole 211, thereby increasing the path traveled by the medicine liquid after being discharged, and the permeability of the medicine liquid in this state is better.

[0034] To sum up, the forest fertilization device, by providing an inner rod 230, can occupy the internal space of the outer cylinder 210. Therefore, compared with the prior art of directly placing the liquid medicine completely inside the hollow cylinder, this method can increase the diameter of the outer cylinder 210 under the condition of the same amount of liquid medicine, thereby increasing the external surface area, and increasing the space occupied by the soil, thereby expanding the area occupied by the liquid medicine after being discharged from the leakage hole 211. Therefore, the forest fertilization device provided by the embodiment of the utility model has an expanded fertilization area after a single insertion into the soil, thereby improving the fertilization efficiency and not wasting liquid medicine; a piston 240 is provided, and when the piston 240 moves downward, it can squeeze the liquid medicine in the storage space, so that the liquid medicine has a certain initial velocity when it is discharged from the leakage hole 211, thereby increasing the path traveled by the liquid medicine after being discharged, and the liquid medicine has better permeability in this state.
