[0052] The application discloses a liquid fertilizer gun for fertilizing around the root system of a tree.

[0053] Please refer to Figures 1-2 and Figure 5As shown, the liquid fertilizer gun comprises a handle 1, a main rod 2, a pedal ring 3, a gun head 4, a corrugated tube 5, a liquid supply pipe 6, a first locking mechanism 7 and a second locking mechanism 8. The handle 1 is arranged at a first end of the main rod 2. The handle 1 is adapted to control the opening or closing of the liquid supply pipe 6. A second end of the main rod 2 is sleeved outside a first end of the pedal ring 3 through the first locking mechanism 7. The first locking mechanism 7 is adapted to fix the second end of the main rod 2 and the first end of the pedal ring 3 together under the action of an external force. A first end of the gun head 4 is sleeved outside a second end of the pedal ring 3 through the second locking mechanism 8. The second locking mechanism 8 is adapted to fix the first end of the gun head 4 and the second end of the pedal ring 3 together under the action of an external force. A second end of the gun head 4 is provided with a liquid outlet hole 41. Through the first locking mechanism 7 and the second locking mechanism 8, a staff can adjust the overall height of the liquid fertilizer gun and the position of the pedal ring 3 on the liquid fertilizer gun, so as to adapt to the fertilization needs of different working scenes. The position of the pedal ring 3 on the liquid fertilizer gun (i.e. the height at which the pedal ring 3 is located) is adjusted, so that the staff can comfortably pedal the pedal ring 3.

[0054] The inner cavity of the main rod 2 is connected with the inner cavity of the gun head 4 through the inner cavity of the pedal ring 3, so as to form a channel. The corrugated tube 5 is arranged in the channel. The liquid inlet end of the corrugated tube 5 is connected with the liquid supply pipe 6 through the handle 1. The liquid outlet end of the corrugated tube 5 is connected with the liquid outlet hole 41. In this embodiment, the liquid supply pipe 6 supplies liquid to the liquid outlet hole 41 through the corrugated tube 5. The liquid transported in the liquid supply pipe 6 is liquid fertilizer. The liquid supply pipe 6 is provided with a flow meter 61. The flow meter 61 is adapted to measure the volume of the liquid discharged from the liquid outlet hole 41, so that the staff can accurately dose the fertilization of the trees through the flow meter 61.

[0055] The length of the corrugated tube 5 is adjustable. The corrugated tube 5 stretches or shrinks along with the change of the overall height of the liquid fertilizer gun, so as to adapt to the overall height of the liquid fertilizer gun, and thus ensure that the two ends of the corrugated tube 5 are always effectively connected with the liquid supply pipe 6 and the liquid outlet hole 41.

[0056] As shown in Figure 1 The handle 1 comprises a handle 11 and a control valve 12. The control valve 12 is adapted to control the opening or closing of the liquid supply pipe 6.

[0057] As shown in Figure 1 and Figure 4 The pedal ring 3 is an axisymmetric structure. The axis of symmetry of the pedal ring 3 coincides with the central axis of the gun head 4, so that the force application position of the liquid fertilizer gun is located directly above the gun head 4, and thus the gun head 4 can be accurately inserted into the soil to effectively fertilize the trees, effectively avoiding the insertion deviation of the gun head 4 (i.e. preventing the gun head 4 from deviating from the root system around the trees).

[0058] Specifically, the stepping ring 3 comprises a ring body 31, a first screw rod 32 and a second screw rod 33. The first screw rod 32 and the second screw rod 33 are respectively arranged at two ends of the ring body 31. The inner cavity of the first screw rod 32 is connected with the inner cavity of the second screw rod 33 through the inner cavity of the ring body 31. The second end of the main rod 2 is sleeved outside the first screw rod 32 through the first locking mechanism 7. The first end of the gun head 4 is sleeved outside the second screw rod 33 through the second locking mechanism 8.

[0059] In the embodiment, the ring body 31 is an axisymmetric structure. The axis of symmetry of the ring body 31, the first screw rod 32, the second screw rod 33, the main rod 2 and the gun head 4 are coaxially arranged.

[0060] Further, the inner circle of the ring body 31 is approximately pentagonal. In the embodiment, the ring body 31 is made by bending a circular tube. The bottom edge of the ring body 31 is horizontally arranged, and the surface of the bottom edge of the ring body 31 is provided with anti-skid protrusions for anti-skid effect.

[0061] Further, the main rod 2 is threadedly connected with the first screw rod 32. The first locking mechanism 7 comprises at least two first nuts. The at least two first nuts are all screwed on the first screw rod 32, and the adjacent two first nuts abut each other. The first nut close to the main rod 2 abuts the end surface of the main rod 2. In the embodiment, the first nuts are two. The axial force generated between the two first nuts increases the friction force between the nut teeth of the first nut and the bolt teeth of the first screw rod 32, so as to prevent the first nut from automatically loosening, thereby realizing the fastening between the main rod 2 and the first screw rod 32.

[0062] Further, the gun head 4 is threadedly connected with the second screw rod 33. The second locking mechanism 8 comprises at least two second nuts. The at least two second nuts are all screwed on the second screw rod 33, and the adjacent two second nuts abut each other. The second nut close to the gun head 4 abuts the end surface of the gun head 4. In the embodiment, the second nuts are two. The axial force generated between the two second nuts increases the friction force between the nut teeth of the second nut and the bolt teeth of the second screw rod 33, so as to prevent the second screw rod 33 from automatically loosening, thereby realizing the fastening between the gun head 4 and the second screw rod 33.

[0063] Please refer to Figure 1 , Figure 3 and Figure 6As shown, the liquid fertilizer gun further comprises a soil scraping assembly 9. The soil scraping assembly 9 is sleeved on the gun head 4. The soil scraping assembly 9 is adapted to scrape the soil attached near the liquid outlet hole 41 to prevent the liquid outlet hole 41 from being blocked. Specifically, the soil scraping assembly 9 comprises a sleeve 91 and a spring 92. The sleeve 91 is sleeved on the gun head 4 in a sliding manner. The outer wall of the gun head 4 is provided with a limiting protrusion 42. The limiting protrusion 42 is located in the inner cavity of the sleeve 91. The spring 92 is sleeved on the gun head 4. The spring 92 is located in the inner cavity of the sleeve 91. One end of the spring 92 is fixed on the sleeve 91. The other end of the spring 92 is fixed on the limiting protrusion 42.

[0064] When the gun head 4 is inserted into the soil, the sleeve 91 moves away from the soil under the action of the soil (i.e., the sleeve 91 moves upward) to expose the liquid outlet hole 41. At this time, the spring 92 is in a stretched state. When the gun head 4 is pulled out of the soil, the spring 92 rebounds to reset the sleeve 91 (i.e., the sleeve 91 moves downward). At this time, the sleeve 91 scrapes the soil attached near the liquid outlet hole 41 and covers the liquid outlet hole 41.

[0065] Further, in order to effectively scrape the soil attached near the liquid outlet hole 41, the soil scraping end of the sleeve 91 is provided with a scraping edge. The scraping edge is in contact with the outer wall of the gun head 4.

[0066] Further, the liquid fertilizer gun further comprises a protective sleeve (not shown in the figure). The protective sleeve is adapted to be detachably sleeved on the sharp head of the gun head 4 to prevent accidental injury caused by the sharp head of the gun head 4. When the liquid fertilizer gun is idle, the protective sleeve can be sleeved on the sharp head of the gun head 4 to reduce the safety hazard.

[0067] In this embodiment, the working principle of the liquid fertilizer gun is as follows:

[0068] According to the needs of the staff, the staff adjusts the overall height of the liquid fertilizer gun and the position of the stepping ring 3 on the liquid fertilizer gun through the first locking mechanism 7 and the second locking mechanism 8.

[0069] The staff steps down the stepping ring 3 to insert the gun head 4 into the soil. At this time, the sleeve 91 moves upward to expose the liquid outlet hole 41, and the spring 92 is in a stretched state.

[0070] After the gun head 4 is inserted into the soil to a certain depth, the staff opens the control valve 12 to inject the liquid fertilizer in the liquid supply pipe 6 into the soil through the liquid outlet hole 41.

[0071] When the staff determines through the flowmeter 61 that the dose of the liquid fertilizer injected into the soil has met the fertilization demand, the staff closes the control valve 12 to stop fertilization.

[0072] After that, the staff member pulls the liquid fertilizer gun out of the soil.

[0073] In summary, the liquid fertilizer gun provided by the present application improves the adaptability and fertilization effect of the liquid fertilizer gun by adjusting the overall height of the liquid fertilizer gun and the position of the stepping ring on the liquid fertilizer gun through the first locking mechanism and the second locking mechanism on the basis of adding a flowmeter, so as to accurately insert into the soil and inject a precise dose of liquid fertilizer. By setting the mud scraping assembly, the liquid outlet hole is prevented from being blocked. By setting the protective sleeve, accidental injury caused by the sharp head of the gun head is prevented.

[0074] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
