Technical Field

[0002] Fertilization in gardening is an important part of ensuring healthy plant growth and beautiful landscape. In modern gardening maintenance, fertilization is an extremely critical part. It is directly related to the growth of garden plants, landscape effects and ecological functions. At the same time, with the deepening of the concept of refined management of garden landscapes, different types of garden plants have specific and strict requirements on the type, quantity and depth of fertilizer at different growth stages. Therefore, precise fertilization has become an inevitable trend. In the traditional gardening fertilization process, the commonly used method is surface spreading, which makes it impossible for garden plants to get the most suitable nutrient supply in the traditional fertilization method, such as:

[0003] Since the roots of garden trees are deep, the roots of some trees can penetrate 1-2 meters or even deeper into the ground. The traditional surface-spread fertilizer can only penetrate into the shallow soil surface. The roots need to spend more energy to absorb nutrients, making the overall absorption efficiency low. In addition, the fertilizer sprinkled on the surface is easily affected by natural factors. After the rain, a large amount of fertilizer will be lost with the rainwater, which not only reduces the utilization rate of the fertilizer, but also may cause pollution to the surrounding water environment.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original landscaping fertilization equipment. Summary of the invention

[0036] Compared with the prior art, the beneficial effects of the present invention are: the landscaping fertilization device capable of deep position treatment:

[0037] 1. A drilling type injection assembly is arranged at the bottom of the electric drive slide 1 and the electric drive slide 2 in the device. The overall height of the drilling type injection assembly is adjusted with the driving of the hydraulic column. By adjusting the position of the electric drive slide 1 and the electric drive slide 2, the fixed-point delivery of the fertilization position of the garden landscaping data is realized, so that the fertilizer can accurately enter the root part of the plant. When the garden landscaping data is injected with fertilizer, as the height of the hydraulic column decreases, the threaded rod is close to the soil surface, and the pressure column and the motor are used together to directly reach the root part of the plant. As the injection ring releases liquid fertilizer, the liquid fertilizer enters the drilling depth along the spiral groove of the threaded rod, and the fertilizer is accurately delivered to the deep soil position where the plant root system is more distributed. By delivering the fertilizer to the deep position of the fabric root system, the loss of fertilizer caused by rainwater erosion, surface runoff and volatilization is reduced. While ensuring the nutritional needs of the plant, the amount of fertilizer used can be reduced, the fertilization cost is reduced, and precise fertilization is achieved;

[0038] 2. When the threaded rod is drilled into the root part of the plant, the liquid fertilizer sent out by opening the four pressure valves through the injection ring close to the groove position of the threaded rod is evenly set with small holes in the spiral groove of the threaded rod. Even when the threaded rod is lowered for use, the small holes in the spiral groove of the electric drive slide provide a more convenient circulation method for liquid fertilizer delivery, which is convenient for introducing the liquid into the interior of the threaded rod, and then penetrates into the deep soil through the surface of the threaded rod along the spiral groove and the small holes. The liquid flows out through the small holes and the opening position of the hollow part and enters the soil to be directly delivered to the deep position of the plant root system, so that the overall structure of the threaded rod is similar to that of some drip irrigation or infiltration irrigation equipment, so that the liquid is dispersed into the soil at a certain rate and method.

[0057] In conjunction with the accompanying drawings Figure 1-Figure 10 As shown, the crawler mobile chassis 2 adopts a crawler structure in four directions, which is electrically driven to assist the overall movement of the equipment. The hydraulic column 3 arranged on the upper end of the carrying platform 1 provides assistance for the overall height change. The hydraulic column 3 is driven by the oil tank 4 and the controller 5 to realize the change of the lifting height.

[0058] The arc-shaped bellows 12 in the arc-shaped raised frame at the upper end of the electric drive slide 7 is automatically extended and recovered as the electric drive slide 2 16 rotates. The arc-shaped raised frame at the upper end of the electric drive slide 7 plays a limiting role. At the same time, the arc-shaped raised frame and the side walls of the electric drive slide 1 14 and the electric drive slide 2 16 are prevented from leaving a gap and not contacting each other, thereby reducing the friction between the arc-shaped bellows 12 and the tree surface. The arc-shaped bellows 12 is used to connect the electric control valve 11 of the liquid fertilizer storage box 8 to provide liquid fertilizer for the hydraulic pump 1 13 and the hydraulic pump 2 15. The electric drive stirring blades 9 arranged inside the liquid fertilizer storage box 8 provide stable stirring for the liquid fertilizer to avoid liquid fertilizer deposition. The sealing cover 10 installed above the liquid fertilizer storage box 8 further provides protection. When in use, the hydraulic pump 1 13 and the hydraulic pump 2 15 are respectively connected to two liquid delivery pipes 23, such as Figure 1 and Figure 4-Figure 5 As shown, the hydraulic pump 13 and the hydraulic pump 2 15 are synchronously connected and controlled with the battery and the controller 5, so as to cooperate with the drilling injection assembly to realize deep position fertilization for greening;

[0059] The drill-in injection assembly includes:

[0060] The limiting frame 18 is arranged at the bottom end of the positioning tube 17, and the side wall of the limiting frame 18 is symmetrically provided with two strip openings, the outer wall of the limiting frame 18 is covered with an annular silicone sleeve, and the annular silicone sleeve is penetrated by the liquid delivery tube 23, and the inner wall of the limiting frame 18 is provided with two liquid injection rings 22 in a vertical direction;

[0061] A pressurizing column 19 is installed in the positioning tube 17, and the pressurizing column 19 is a rod structure with two sections of sliding connection;

[0062] The motor 20 is installed in the limiting frame 18, and the top end of the motor 20 is connected to the rod body at the output end of the pressure column 19;

[0063] The threaded rod 21 is connected to the output end of the motor 20, and the threaded rod 21 is arranged in a concentric circle inside the limit frame 18. The inside of the threaded rod 21 is arranged as a hollow structure, and the spiral groove on the surface of the threaded rod 21 is evenly provided with small holes connected to the hollow structure, and a gap is left between the threaded rod 21 and the injection ring 22;

[0064] A liquid injection ring 22 is installed on the inner wall of the limiting frame 18, and the liquid injection ring 22 is penetrated by the threaded rod 21. An annular cavity is provided in the liquid injection ring 22, and the cavity of the liquid injection ring 22 is connected to the liquid delivery pipe 23 and the pressure valve 24. The liquid injection ring 22 is connected to the liquid delivery pipe 23, and the liquid delivery pipe 23 penetrates the limiting frame 18;

[0065] The pressure valve 24 is installed in the liquid injection ring 22, and the output opening of the pressure valve 24 for discharging liquid passes through the liquid injection ring 22, and the output opening of the pressure valve 24 for discharging liquid is close to the threaded rod 21;

[0066] In conjunction with the accompanying drawings Figure 1-Figure 10 As shown, with the positioning tube 17 and the limiting frame 18 connected to form a pipeline structure, as shown in Figure 5 and Figure 7 As shown, a group of drilling-type injection assembly structures are installed at the bottom of the electric drive slide 14 and the electric drive slide 2 16 respectively. The pressure column 19 arranged inside the positioning tube 17 adopts a hydraulic structure, and the oil tank 4 assists in cooperation, so that the pressure column 19 pushes the motor 20 and the threaded rod 21 to adjust the height, so that the threaded rod 21 is deeply drilled into the fertilization part of the greening tree that needs to be in-depth. The threaded rod 21 works by rotating the output end of the motor 20, and the wire of the motor 20 passes through the noodle-shaped opening on the side wall of the limit frame 18. The liquid injection ring 22 is connected to the battery at the upper end of the electric drive push plate 6 for power supply. The liquid injection ring 22 is an annular structure made of corrosion-resistant silicone. During the rotation and descent of the threaded rod 21, the liquid injection ring 22 limits the movement of the threaded rod 21 to prevent the threaded rod 21 from shaking left and right and affecting the drilling depth. When the threaded rod 21 is started to rotate, the pressure column 19 slowly pushes the motor 20 down, so that the threaded rod 21 gradually drills into the fixed point required for greening. After reaching the specified depth, the pressure column 19 lifts the threaded rod 21. At this time, the hydraulic column 3 cooperates with the overall height adjustment. It is convenient to remove the excess soil on the surface of the threaded rod 21, and then the threaded rod 21 enters the hole again, and the hydraulic pump 13 and the electric drive slide 14 are started synchronously to inject liquid fertilizer into the liquid delivery pipe 23. At this time, the pressure valve 24 is opened after the liquid injection inside the injection ring 22 reaches a certain pressure, so that the liquid fertilizer flows to the threaded rod 21, and gradually goes down along the spiral groove of the threaded rod 21 to penetrate into the root system of the green plant soil for fixed-point depth fertilization. The pressure valve 24 is a spring-type pressure safety valve, which has a compression spring inside to provide the force to close the valve. When the injection ring 2 When the upward force generated by the fluid pressure in 2 acting on the valve core is greater than the preload force of the spring, the valve core will be lifted up, the pressure valve 24 will open, and the fluid can flow out through the valve to achieve fertilization. When fertilizing at shallow depth, according to the soil absorption condition, the threaded rod 21 is not lifted, and liquid fertilizer is directly injected into the injection ring 22, so that the liquid is injected into the shallow soil of the drilled loose part along the threaded rod 21. Since the hollow structure in the threaded rod 21 receives the liquid fertilizer passing through the spiral groove holes of the threaded rod 21 and inputs it into the soil, Figure 8 As shown, deep fertilization can be achieved, which can effectively transport liquid to a specific depth to meet the water and nutrient needs of plant roots.

[0067] Working principle: When using the gardening fertilization device capable of deep-position processing, first, the crawler-type mobile chassis 2 at the bottom of the carrying platform 1 provides power for the overall displacement, so that the device as a whole is close to the gardening trees. When in use, the electric drive slide 2 16 and the electric drive slide 1 14 are inside the electric drive slide 7, so that the C-shaped opening of the electric drive slide 7 passes through the trunk of the gardening tree. Then, after the electric drive slide 7 is close to the gardening tree and presents a semi-wrapped state, the electric drive slide 2 16 and the electric drive slide 1 14 are moved in a symmetrical direction inside the electric drive slide 7. The height of the electric drive slide 7 is changed by adjusting the height through the hydraulic column 3, so that the threaded rod 21 stands in the soil part of the greening tree, and the motor 20 drives the threaded rod 21 to rotate and drill into it, and the pressurized column 19 is used to push the threaded rod 21 down to a suitable depth near the root system of the greening tree, and then stop, according to the delivery The material needs to start the pressurizing column 19 to lift the threaded rod 21 to clear the accumulated soil on the surface and then enter the original hole here, or directly start the hydraulic pump 13 and the hydraulic pump 2 15 to obtain liquid fertilizer from the liquid fertilizer storage box 8, further pressurize it and send it into the liquid delivery pipe 23, and the liquid fertilizer flowing in the liquid delivery pipe 23 is filled into the injection ring 22. As the pressure increases, the pressure valve 24 in the injection ring 22 opens, so that the liquid fertilizer follows the spiral groove on the surface of the threaded rod 21 and passes through the small holes in the spiral groove of the threaded rod 21 along the hollow pipe to gradually penetrate into the underground hole. After the liquid fertilizer is injected, the threaded rod 21 is lifted, and the excess soil drilled out is returned. After that, the electric drive slide 2 16 and the electric drive slide 1 14 rotate in the electric drive slide 7 without blocking the opening of the electric drive slide 7, which is convenient for the crawler mobile chassis 2 to move, so that the electric drive slide 7 is away from the garden trees, thereby realizing deep fixed-point fertilization.

[0068] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
