Description

Technical Field

[0001] This utility model belongs to the field of forest irrigation technology, and more specifically, it relates to a mountain forest water and fertilizer irrigation device. Background Technology

[0002] Tree planting in mountainous areas presents challenges due to complex terrain, hard soil, and overgrown weeds, as well as large planting spacing. Traditional large-scale irrigation equipment is difficult to access, and manual application of water and fertilizer is extremely difficult and prone to waste. Therefore, there is an urgent need to design a portable electric water and fertilizer application device for mountainous areas. While an existing technology exists for applying fertilizer and water to flue-cured tobacco fields (publication number CN220044452U), which connects a portable electric water and fertilizer applicator to a fertilizer gun, allowing the fertilizer and water to be carried to the field and the fertilizer gun inserted downwards into the soil for spraying, reducing fertilizer and water loss, the existing technology features horizontally positioned water outlets and uses a scraper to clear soil from the outside of the outlets to prevent clogging. This not only results in a complex anti-clogging structure and cumbersome operation, but the gaps in the scraper's vertical movement also easily trap soil, affecting operation. Furthermore, its design is primarily geared towards field environments and is unsuitable for use in mountainous areas, necessitating improvement. Utility Model Content

[0003] One object of this invention is to solve at least the aforementioned defects and to provide at least the advantages described below.

[0004] This utility model provides a mountain forest water and fertilizer irrigation device, which aims to provide a mountain forest water and fertilizer irrigation device with simple structure, convenient operation, suitable for mountain forest environment and conducive to saving water and fertilizer.

[0005] This utility model provides a forest irrigation device, which includes a backpack-type electric water and fertilizer generator and a fertilizer applicator. The fertilizer applicator includes a hollow, rigid barrel with a handle at the upper end and a drill bit at the lower end. The hollow part of the barrel is connected to the backpack-type electric water and fertilizer generator through a water pipe. One or more water outlet holes, either vertically downward or inclined downward, are provided through the lower side of the barrel and the hollow part. The drill bit includes an inverted conical structure that is larger at the top and smaller at the bottom, with the upper dimension of the inverted conical structure being larger than the lower dimension of the barrel, such that the one or more water outlet holes are located in the recessed space formed between the drill bit and the barrel.

[0006] Preferably, a foot pedal that can be folded upwards is provided at the lower part of the gun barrel.

[0007] Preferably, the drill bit also includes a frustum structure, the lower bottom surface of which is connected to the upper end of the inverted conical structure, and gear teeth are provided on the outer edge of the formed frustum structure. The lower end of the drill rod is disposed on the upper bottom surface of the frustum structure, and the lower opening of the water outlet is close to the side of the frustum structure.

[0008] Preferably, a cylinder is provided inside the gun barrel, and a rotating shaft is rotatably installed inside the cylinder. The upper end of the rotating shaft is connected to the output end of the motor, and the lower end of the rotating shaft is fixed to the drill bit. The outer surface of the inverted conical structure of the drill bit is provided with a downward spiral thread for spiral drilling and unscrewing. The channel formed between the inner wall of the hollow lower part of the gun barrel and the outer wall of the cylinder communicates with the water supply pipe and is connected to one or more water outlet holes, so as to allow the water and fertilizer of the backpack electric water and fertilizer device to flow out sequentially from the water supply pipe, the channel, and the water outlet holes.

[0009] Preferably, a wheel frame is provided at the lower part of the gun barrel, the upper end of the wheel frame is hinged to the side wall of the gun barrel, and the lower end is provided with a caster wheel; a support frame is provided on the wheel frame, one end of the support frame is hinged to the wheel frame, and the other end is provided with an arc-shaped plate adapted to the outer diameter of the lower part of the gun barrel for supporting the gun barrel; wherein, the hinge axis of the support frame is parallel to the hinge axis of the wheel frame.

[0010] Preferably, a buffer layer is provided on the contact surface between the arc-shaped plate and the gun barrel.

[0011] This utility model has at least the following beneficial effects:

[0012] First, this utility model combines a backpack-type electric water and fertilizer device with a fertilizer and water applicator, enabling convenient and effective water and fertilizer irrigation in mountainous and forest environments, thus solving the problem that traditional irrigation equipment is difficult to enter mountainous and forest environments.

[0013] Secondly, the drill bit of the fertilizer applicator designed in this utility model includes an inverted conical structure that is larger at the top and smaller at the bottom, and the water outlet is located in the recessed space formed between the drill bit and the gun rod. This not only creates a water outlet space in the relatively firm soil of the forest, but also reduces the clogging of the water outlet by the soil, thereby improving the fertilization efficiency.

[0014] Third, the design of this utility model, which combines the foot pedal, wheel frame, and support frame, makes it easy for the operator to firmly press the gun barrel into the hard soil and walk conveniently in the mountainous environment, saving effort.

[0015] Fourth, the electric motor drives the drill bit to drill down and out in a spiral motion, which improves the drilling effect in the soil, further saves effort, and improves fertilization efficiency.

[0016] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0025] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are conventional methods, and the reagents and materials described are commercially available. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Figures 1-2 The illustration shows an implementation of a forest irrigation device, comprising a backpack-mounted electric irrigator 1 and an irrigator 22. The irrigator 22 is characterized by a hollow, rigid barrel 3 with a handle 4 at its upper end and a drill bit 21 at its lower end. The hollow portion 5 of the barrel is connected to the backpack-mounted electric irrigator 1 via a water pipe 2. One or more water outlet holes 8, either vertically downwards or inclined downwards, are formed through the lower side of the barrel 3 and the hollow portion 5. The drill bit 21 includes an inverted conical structure 7, larger at the top and smaller at the bottom. The upper dimension of the inverted conical structure 7 is larger than the lower dimension of the barrel 3 but less than twice the lower dimension, such that the one or more water outlet holes 8 are located in the recessed space formed between the drill bit 21 and the barrel 3. This invention solves the problem of fertilizer waste in forests and creates a water outlet space in the relatively firm soil of forests. This facilitates the application of water and fertilizer into the pit during drilling and spraying, and also reduces the problem of soil clogging the water outlet 8. The rigid gun rod 3 and the drill bit 21 are required to have rigidity and strength to withstand various loads and pressures, meeting the usage requirements of this invention. The drill bit 21 can be solid, making it easy to insert into the soil using gravity and inertia. The lower side of the gun rod 3 where the water outlet 8 is located can be tilted inward to form an inclined surface, which facilitates the water outlet 8 to be vertically downward or tilted downward.

[0027] In the above technical solution, the drill bit 21 of this utility model adopts an inverted conical structure 7 that is larger at the top and smaller at the bottom. This design not only facilitates the drill bit 21 to easily insert into hard soil using its own weight and the pressure applied by the operator, but also intentionally designs the upper end of its inverted conical structure 7 to be larger than the lower end of the gun rod 3, thus forming a recessed space between the drill bit 21 and the gun rod 3. Within this space, one or more vertically downward or inclined downward water outlet holes 8 are carefully opened on the lower side of the gun rod 3. These water outlet holes 8 are directly connected to the hollow part 5 of the gun rod and are tightly connected to the backpack electric water and fertilizer device 1 through the water supply pipe 2. This design ensures that water and fertilizer can be sprayed into the pit drilled by the drill bit 21 through the water outlet holes 8, effectively reducing the waste of water and fertilizer and effectively preventing the soil from clogging the water outlet holes 8.

[0028] This invention explains the material selection and strength requirements: Considering the special characteristics of the mountain forest environment, both the rigid gun barrel 3 and the drill bit 21 are made of materials with high rigidity and strength to ensure that they can withstand various loads and pressures that may be encountered during use, including but not limited to soil compression, rock collisions, and long-term wear. The solid design of the drill bit 21 further enhances its penetrating power, allowing it to easily handle even the hardest soil.

[0029] The usage process of this utility model is demonstrated as follows:

[0030] I. Preparation Stage:

[0031] First, the operator needs to fully charge the backpack electric fertigation unit 1 to ensure it has enough power to drive the entire irrigation process.

[0032] Next, inspect all components of the fertilizer applicator 22, including the rigid gun rod 3, drill bit 21, water outlet 8, and water pipe 2, to ensure they are all in good condition, and then fill the fertilizer applicator 22 with the fertilizer-water mixture.

[0033] Finally, the operator carries the backpack-mounted electric water and fertilizer device 1 on their back and holds the fertilizer and water applicator 22 in their hand, ready to enter the mountain forest for irrigation.

[0034] II. Positioning and Drilling:

[0035] Once the operator arrives at the target irrigation area, they select a suitable irrigation point based on the planting location and spacing of the trees.

[0036] Holding the handle 4, using the weight of the drill bit 21 and its own strength, aim the drill bit 21 at the selected irrigation point, press down hard or rotate appropriately, so that the drill bit 21 can be easily inserted into the hard soil.

[0037] As the drill bit 21 is inserted into the soil, its inverted conical structure 7 gradually expands the borehole. At the same time, the recessed space formed between the drill bit 21 and the gun barrel 3 provides sufficient spray space for the water outlet 8.

[0038] III. Irrigation and Fertilization:

[0039] Once the drill bit 21 is inserted to the predetermined depth, the operator controls the electric pump to start via the switch button of the backpack electric slurry pump 1, which then delivers the slurry mixture through the water pipe 2 to the hollow part 5 of the gun barrel.

[0040] The water-fertilizer mixture is then sprayed vertically or obliquely downward into the pit drilled by the drill bit 21 through the water outlet 8 at the lower end of the gun rod 3.

[0041] Since the water outlet 8 is located in the recessed space between the drill bit 21 and the gun rod 3, the water and fertilizer can flow directly into the pit, avoiding the blockage of the water outlet 8 by the soil, and also reducing the waste of water and fertilizer.

[0042] IV. End and Move:

[0043] Once irrigation is complete (that is, the set irrigation volume is reached according to the pump flow rate of the electric fertigation unit), the operator turns off the electric fertigation unit to stop the delivery of water and fertilizer.

[0044] Gently rotate and pull out the drill bit 21. If it is equipped with gear teeth 10 on the outer edge, it can help loosen the soil and fill the water and fertilizer, which is conducive to the mixing of soil and water and fertilizer and filling.

[0045] The operator can then move to the next irrigation point and repeat the process until the irrigation of the entire forest is completed.

[0046] Based on the above implementation, a foot pedal 6 that can be folded upwards is provided at the lower part of the gun barrel 3. This design, by stepping on the foot pedal 6, helps to stabilize the lower end of the barrel and press it into the hard soil.

[0047] Based on the above implementation methods, such as Figure 3 As shown, the drill bit 21 also includes a frustum structure 9, the lower surface of which is connected to the upper end of the inverted conical structure 7 (this connection can be fixed splicing or integral molding), and gear teeth 10 are provided on the outer edge of the formed connection. The lower end of the gun rod 3 is set on the upper surface of the frustum structure 9, and the lower opening of the water outlet 8 is close to the side of the frustum structure 9. This design of the drill bit 21, including the frustum structure 9 and gear teeth 10, allows the drill bit 21 to be rotated during the process of pulling it out, thereby loosening and burying the water and fertilizer in the mud pit.

[0048] Based on the above implementation methods, such as Figure 4As shown, a cylinder 13 is installed inside the gun barrel 3, and a rotating shaft 14 is rotatably installed inside the cylinder 13. The upper end of the rotating shaft 14 is connected to the output end of the motor 11, and the lower end of the rotating shaft 14 is fixedly connected to the drill bit 21. The outer surface of the inverted conical structure 7 of the drill bit 21 is provided with a downward spiral thread for spiral drilling and unscrewing, improving the drilling effect of the drill bit 21. The channel 12 formed between the inner wall of the hollow lower part of the gun barrel 3 and the outer wall of the cylinder 13 is connected to the water supply pipe 2 and is connected to one or more water outlet holes 8, for the water and fertilizer of the backpack electric water and fertilizer device 1 to flow out sequentially from the water supply pipe 2, the channel 12, and the water outlet holes 8. This design is beneficial for the drill bit 21 to be driven by the motor 11 to drill into the relatively firm soil of the forest, saving effort and improving efficiency. In the specific design, a bearing 15 is fixed at the lower end of the gun barrel 3, and the inner ring of the bearing 15 is passed through the lower end of the rotating shaft 14 for rotatable connection, so that the drill bit 21 is rotatably connected to the lower end of the gun barrel 3. The motor 11 is equipped with a rechargeable lithium-ion battery or a nickel-cadmium battery for easy use.

[0049] Based on the above implementation methods, such as Figure 5-6 As shown, a wheel frame 16 is provided at the lower part of the gun barrel 3. The upper end of the wheel frame 16 is hinged to the side wall of the gun barrel 3, and the lower end is provided with casters. A support frame 18 is provided on the wheel frame 16. One end of the support frame 18 is hinged to the wheel frame 16, and the other end is provided with an arc-shaped plate 20 adapted to the lower outer diameter of the gun barrel 3 for supporting the gun barrel 3. The hinge axis 19 of the support frame is parallel to the hinge axis 17 of the wheel frame. This design facilitates the unfolding of the wheel frame 16, supporting the gun barrel 3 for walking, eliminating the need to carry the gun barrel 3, saving effort, and meeting the irrigation needs of mountain forests with large planting spacing of seedlings.

[0050] In the above-described technical solution of this utility model, a cylinder 13 is provided inside the gun barrel 3, and a rotating shaft 14 is rotatably installed inside the cylinder 13. The upper end of the rotating shaft 14 is tightly connected to the output end of the motor 11 through a transmission device (such as gears), while the lower end is firmly fixed to the drill bit 21. The outer surface of the inverted conical structure 7 of the drill bit 21 is engraved with a downward spiral thread. This design allows the drill bit 21 to easily screw into hard soil like a screw under the drive of the motor 11, and it is also easy to unscrew, greatly improving the drilling effect and working efficiency of the drill bit 21. The motor 11 is powered by a rechargeable lithium-ion battery or a nickel-cadmium battery, ensuring the portability of the equipment and its long-term working capability.

[0051] Furthermore, an annular channel 12 is formed between the lower hollow part of the gun rod 3 and the outer wall of the cylinder 13. This channel 12 is tightly connected to the water supply pipe 2 and communicates with the water outlet 8 at the lower end of the gun rod 3. In this way, the water-fertilizer mixture in the backpack electric water-fertilizer 1 can be sprayed into the pit drilled by the drill bit 21 through the water supply pipe 2, the channel 12 and the water outlet 8, realizing the efficient utilization of water and fertilizer.

[0052] To reduce the operator's burden, a wheel frame 16 is installed at the lower part of the gun barrel 3. The upper end of the wheel frame 16 is hinged to the side wall of the gun barrel 3, allowing it to be easily unfolded or folded up. The lower end of the wheel frame 16 is equipped with casters, making the equipment more flexible when moving. In addition, a support frame 18 is also equipped on the wheel frame 16. One end of the support frame 18 is hinged to the wheel frame 16, and the other end is equipped with an arc-shaped plate 20 that matches the outer diameter of the lower part of the gun barrel 3. When the equipment needs to be moved, simply unfold the wheel frame 16 and the support frame 18 to support the gun barrel 3, and the operator can easily pull the equipment without having to carry the heavy gun barrel 3.

[0053] Usage process:

[0054] Preparation stage: The operator first checks whether all parts of the equipment are intact, especially key components such as motor 11, drill bit 21, water outlet 8, wheel frame 16, and support frame 18. Then, the operator puts on the backpack electric water and fertilizer device 1, unfolds the wheel frame 16 and support frame 18, supports the gun rod 3, and pulls the fertilizer and water applicator 22 to walk into the mountains for irrigation.

[0055] Positioning and drilling: After arriving at the target irrigation area, the operator determines the irrigation location and retracts the wheel frame 16 and support frame 18. Then, using the driving force of the motor 11 and the spiral thread design of the drill bit 21, the drill bit 21 is screwed into the soil.

[0056] Irrigation and fertilization: After the drill bit 21 is inserted to the predetermined depth, the operator turns off the motor 11 and then controls the electric pump to start by using the switch button of the backpack electric water and fertilizer device 1. The water and fertilizer mixture is sprayed vertically or obliquely downward into the pit drilled by the drill bit 21 through the water outlet 8 at the lower end of the gun rod 3.

[0057] Movement and End: After irrigation is complete, the operator turns off the electric fertigation unit. Then, the drill bit 21 is retracted, and the equipment is moved to the next irrigation point to repeat the above process.

[0058] Based on the above implementation, a buffer layer, such as a rubber layer, is provided on the contact surface between the arc plate 20 and the gun rod 3 to realize the shock absorption effect of the arc plate 20 of the support frame 18 on the fertilizer applicator 22 during the movement process.

[0059] Based on the above implementation, multiple spaced sponge pads can be provided on the surface of the carrying strap of the liquid storage tank of the backpack electric slurry and fertilizer device 1 to improve the carrying comfort of the backpack electric slurry and fertilizer device 1. The backpack electric slurry and fertilizer device 1 includes a liquid storage tank, an electric pump, and a carrying strap. The carrying strap is connected to the liquid storage tank, the electric pump is located inside the liquid storage tank, and one end of the water supply pipe 2 is connected to the outlet of the electric pump, while the other end of the water supply pipe 2 is connected to the hollow part 5 of the gun rod. The backpack electric slurry and fertilizer device 1 uses existing equipment and is not an improvement of this utility model. For the sake of brevity, it will not be elaborated on further. The electric pump and the switch button for controlling the start and stop of the electric pump are not shown. The switch button can be located on the handle 4 for easy operation.

[0060] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be easily made by those skilled in the art.
