Description

Technical Field

[0001] The utility model relates to the technical field of greening equipment, in particular to a root nutrient delivery device. Background Technique

[0002] The healthy growth of trees depends on the absorption capacity of the roots. Especially during the fertilization process, whether the roots can fully absorb nutrients directly affects the growth rate and yield of the trees. In traditional agricultural practices, fertilization is usually carried out by broadcasting, drip irrigation or spraying. These methods mainly rely on the natural penetration of the soil to conduct nutrients to the tree roots. Due to the adsorption of the soil and runoff, a large amount of fertilizer has been adsorbed by the soil or washed away by rain before reaching the roots, resulting in low effective utilization rate of the fertilizer. Especially in arid or areas with poor soil structure, the fertilizer loss is more serious.

[0003] The patent with the publication number CN220528894U discloses a drip irrigation device for tree roots, including a base. The right side of the top of the base is fixedly installed with a water tank through a bracket. The top of the water tank is rotatably connected with a threaded cylinder through an opening. The threaded cylinder is internally threaded with a threaded rod. The top end of the threaded rod extends into the water tank. One end of the threaded rod extending into the water tank is fixedly installed with a push plate. In the utility model, by starting the motor and opening the valve, the motor drives the second rotating rod to rotate. The rotation of the second rotating rod drives the threaded cylinder to rotate. The rotation of the threaded cylinder drives the push plate to descend. The descent of the push plate fits with the inner wall of the water tank through a sealing gasket to deliver the nutrient solution inside the water tank to the roots of the tree through a dropper for drip irrigation. And the rotation of the second rotating rod drives a plurality of stirring rods to rotate, and the rotation of the stirring rods prevents precipitation from occurring inside the water tank during the drip irrigation process, not only effectively preventing the dropper from being blocked, but also increasing the drip irrigation effect.

[0004] In the specific use process of the above prior art, the base is pushed to the side of the tree to be drip-irrigated through a roller, and then the bottom end of the dropper is inserted into the soil. The nutrient solution inside the water tank is delivered to the roots of the tree through the dropper for drip irrigation. However, each time the dropper is used, it is necessary to insert the dropper into the soil. After multiple uses, the bottom end of the dropper is easily blocked, resulting in the nutrient solution being unable to be smoothly output from the dropper to the roots of the tree, affecting the use. In view of this, we propose a root nutrient delivery device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a root nutrient delivery device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] Root nutrient delivery device, including a bottom plate, which is the basic structure for supporting the entire root nutrient delivery device, bearing each component and providing mobility and stability. In the middle of the top of the bottom plate, there is a liquid storage component, which includes a liquid storage barrel for storing nutrient solution for subsequent pumps to pump out the nutrient solution for delivery. On the top of the bottom plate and near the right side of the liquid storage barrel, there is a pump body. The input end of the pump body is connected to the liquid storage barrel through a liquid extraction pipe, and the output end of the pump body is connected to a liquid delivery hose. The output end of the liquid delivery hose is connected to a delivery component. The pump body pumps out the nutrient solution in the liquid storage barrel through the liquid extraction pipe and transports it to the delivery component through the liquid delivery hose. The delivery component is used to deliver the nutrient solution to the roots;

[0008] The delivery component includes a circular pipe. Near the top of the outer wall of the circular pipe, there is a liquid inlet pipe connected to the liquid delivery hose to allow the nutrient solution to enter the circular pipe. At the bottom of the outer wall of the circular pipe, there are multiple liquid outlet holes, so that the nutrient solution entering the circular pipe can be output from the multiple liquid outlet holes. At the bottom end of the circular pipe, there is an insertion needle, which is beneficial for inserting the circular pipe into the soil. At the top end of the circular pipe, there is an internally threaded pipe, and the circular pipe is connected to the internally threaded pipe. The internally threaded pipe is internally threaded with a threaded rod. At the bottom end of the threaded rod, there is a connecting rod, and at the bottom end of the connecting rod, there is a cylindrical piston. By driving the connecting rod to move up and down through the threaded rod, the connecting rod drives the cylindrical piston to move synchronously. When the bottom of the cylindrical piston abuts against the top of the insertion needle, the multiple liquid outlet holes are blocked by the cylindrical piston, effectively preventing soil from entering the circular pipe during the insertion process of the circular pipe, and thus avoiding the liquid outlet holes being blocked by soil;

[0009] At the top of the cylindrical piston and near the outer edge, there are multiple liquid guiding inclined grooves arranged in a circular array. In the middle of the bottom of the cylindrical piston, there is a liquid outlet channel connected to the multiple liquid guiding inclined grooves. The nutrient solution entering the circular pipe is introduced into the liquid outlet channel from the multiple liquid guiding inclined grooves and finally output from the liquid outlet channel to the lower part of the cylindrical piston, so that the nutrient solution can be output from the liquid outlet holes to the roots.

[0010] Preferably, on the front and back sides of the bottom plate and near the left and right ends, there are rolling wheels rotatably connected, which are used to push the entire device to the position of the tree that needs to be fertilized, facilitating movement and positioning. On the top of the bottom plate and near the left side, there is a push rod, which is used to manually push and pull the device to assist the rolling wheels to make the device move more conveniently.

[0011] Preferably, a bucket cover is flange-connected to the top of the liquid storage bucket, covering the opening of the liquid storage bucket to protect the internal nutrient solution from external contamination and provide installation support for components such as the motor. A motor is provided in the middle of the top of the bucket cover. The output shaft of the motor passes through the top of the bucket cover and is coaxially connected to a rotating shaft. A plurality of stirring rods are provided on the outer wall of the rotating shaft. The rotating shaft is driven by the motor to rotate, so that the rotating shaft drives the plurality of stirring rods to rotate, and the stirring rods stir the nutrient solution to prevent precipitation.

[0012] Preferably, a liquid discharge pipe with a valve is provided at the bottom of the outer wall of the liquid storage bucket for emptying the nutrient solution in the liquid storage bucket and is equipped with a valve to facilitate the control of the liquid discharge process. A liquid injection pipe is provided on the top of the bucket cover, and a lid is threadedly connected to the end of the liquid injection pipe for adding nutrient solution to the liquid storage bucket. The end of the liquid injection pipe is provided with a lid to prevent impurities from entering.

[0013] Preferably, a battery box is further provided on the top of the bottom plate. A battery pack for supplying power to the pump body and the motor is provided in the battery box to provide power for the pump body and the motor, ensuring that the device can operate normally without an external power source.

[0014] Preferably, two hand-held rods are provided symmetrically left and right at the top of the outer wall of the circular tube to facilitate the operator to hold and control the operation of the conveying component.

[0015] Preferably, the diameter of the connecting rod is smaller than the inner diameter of the circular tube to ensure that the nutrient solution can flow downward. The outer wall of the cylindrical piston is in close fit with the inner wall of the circular tube to ensure that the cylindrical piston can block the liquid outlet hole.

[0016] Preferably, two support rods are provided symmetrically front and back at a position near the right side of the top of the bottom plate. An arc-shaped clamping plate is provided at the top of the support rod. The circular tube can be clamped on the two arc-shaped clamping plates. When moving the device, the support rods play a role in supporting and fixing the conveying component, facilitating the storage of the conveying component.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. For this root nutrient conveying device, by setting the threaded rod to drive the cylindrical piston to move up and down, when the bottom of the cylindrical piston abuts against the top of the insertion needle, the liquid outlet hole can be effectively blocked, preventing soil from entering the circular tube when the circular tube is inserted into the soil, thereby preventing the soil from blocking the liquid outlet hole. This design significantly improves the service life and effect of the nutrient conveying device, reducing the problem of poor circulation of the nutrient solution caused by blockage.

[0019] 2. The root nutrient delivery device can effectively stir the nutrient solution in the liquid storage barrel by driving the stirring rod to rotate through the motor, avoiding the precipitation of solid components in the nutrient solution, ensuring that the nutrient solution delivered to the roots is always uniform, and improving the fertilization effect.

[0020] 3. The root nutrient delivery device is provided with rollers and a push rod on the bottom plate, enabling the entire device to be easily moved to the position of the tree that needs fertilization. The design of the rollers and the push rod greatly reduces the labor intensity of manual handling and improves the convenience of operation.

[0021] 4. The root nutrient delivery device is provided with a battery pack in the battery box, which can provide power support for the pump body and the motor, ensuring that the device can still operate normally without an external power supply, and is suitable for various field and forest environments, especially in places where power supply is inconvenient.

[0032] Please refer to Figures 1-7 , the present utility model provides a technical solution:

[0033] A root nutrient delivery device, including a bottom plate 1, which is the basic structure for supporting the entire root nutrient delivery device, bearing each component and providing mobility and stability. In the middle of the top of the bottom plate 1, there is a liquid storage component 4. The liquid storage component 4 includes a liquid storage barrel 40 for storing nutrient solution for subsequent extraction by a pump body 5 for nutrient solution delivery. On the top of the bottom plate 1 and near the right side of the liquid storage barrel 40, there is a pump body 5. The input end of the pump body 5 is connected to the liquid storage barrel 40 through a liquid extraction pipe 50. The output end of the pump body 5 is connected to a liquid delivery hose 51. The output end of the liquid delivery hose 51 is connected to a delivery component 6. The pump body 5 extracts the nutrient solution in the liquid storage barrel 40 through the liquid extraction pipe 50 and delivers it to the delivery component 6 through the liquid delivery hose 51. The delivery component 6 is used to deliver the nutrient solution to the roots;

[0034] The conveying assembly 6 includes a circular tube 60. At a position on the outer wall of the circular tube 60 near the top, there is a liquid inlet tube 600 communicated with the liquid delivery hose 51, so that the nutrient solution enters into the circular tube 60. A plurality of liquid outlet holes 601 are opened at the bottom of the outer wall of the circular tube 60, so that the nutrient solution entering the circular tube 60 can be output from the plurality of liquid outlet holes 601. A needle 61 is provided at the bottom end of the circular tube 60. The needle 61 is conducive to inserting the circular tube 60 into the soil. An internal threaded tube 62 is provided at the top end of the circular tube 60. The circular tube 60 is communicated with the internal threaded tube 62. A threaded rod 63 is threadedly connected inside the internal threaded tube 62. A connecting rod 64 is provided at the bottom end of the threaded rod 63. A cylindrical piston 65 is provided at the bottom end of the connecting rod 64. By driving the threaded rod 63 to drive the connecting rod 64 to move up and down, the connecting rod 64 drives the cylindrical piston 65 to move synchronously. When the bottom of the cylindrical piston 65 abuts against the top of the needle 61, the plurality of liquid outlet holes 601 are blocked by the cylindrical piston 65, thereby effectively preventing the soil from entering the circular tube 60 during the insertion process of the circular tube 60, and further avoiding the liquid outlet holes 601 from being blocked by the soil;

[0035] At a position on the top of the cylindrical piston 65 near the outer edge, a plurality of liquid guiding inclined grooves 650 arranged in an annular array are opened. A liquid outlet channel 651 communicated with the plurality of liquid guiding inclined grooves 650 is opened in the middle of the bottom of the cylindrical piston 65. The nutrient solution entering the circular tube 60 is introduced into the liquid outlet channel 651 from the plurality of liquid guiding inclined grooves 650, and finally output from the liquid outlet channel 651 to the lower part of the cylindrical piston 65, so that the nutrient solution can be output from the liquid outlet holes 601 to the root of the tree.

[0036] In this embodiment, rollers 2 are rotatably connected to both the front and rear sides of the bottom plate 1 near the left and right ends, which are used to push the entire device to the position of the tree to be fertilized, facilitating movement and positioning. A push rod 3 is provided at the top of the bottom plate 1 near the left side, which is used to manually push and pull the device to assist the rollers 2 to make the device move more conveniently. Two rollers 2 close to the push rod 3 are universal wheels with brakes, and two rollers 2 far from the push rod 3 are directional wheels.

[0037] Specifically, the top of the liquid storage barrel 40 is flange-connected with a barrel cover 41, which covers the opening of the liquid storage barrel 40, protects the internal nutrient solution from external pollution, and provides installation support for components such as the motor 42. Tiny ventilation holes are opened on the barrel cover 41. A motor 42 is provided in the middle of the top of the barrel cover 41. The output shaft of the motor 42 passes through the top of the barrel cover 41 and is coaxially connected with a rotating shaft 43. A plurality of stirring rods 44 are provided on the outer wall of the rotating shaft 43. By driving the rotating shaft 43 to rotate by the motor 42, the rotating shaft 43 drives the plurality of stirring rods 44 to rotate, so that the stirring rods 44 stir the nutrient solution to prevent precipitation.

[0038] Furthermore, a liquid discharge pipe 400 with a valve is provided at the bottom of the outer wall of the liquid storage barrel 40 for emptying the nutrient solution in the liquid storage barrel 40. The valve is provided to facilitate the control of the liquid discharge process. A liquid injection pipe 410 is provided at the top of the barrel cover 41. The end of the liquid injection pipe 410 is threadedly connected with a lid for adding nutrient solution into the liquid storage barrel 40. The end of the liquid injection pipe 410 is provided with a lid to prevent impurities from entering.

[0039] Furthermore, a battery box 8 is also provided at the top of the bottom plate 1. A battery pack for supplying power to the pump body 5 and the motor 42 is provided in the battery box 8 to provide power for the pump body 5 and the motor 42, ensuring that the device can work normally without an external power source.

[0040] Furthermore, two hand-held rods 602 arranged symmetrically left and right are provided at the top of the outer wall of the circular tube 60, facilitating the operator to hold and control the operation of the conveying component 6.

[0041] Furthermore, the diameter of the connecting rod 64 is smaller than the inner diameter of the circular tube 60 to ensure that the nutrient solution can flow downward. The outer wall of the cylindrical piston 65 is in close fit with the inner wall of the circular tube 60 to ensure that the cylindrical piston 65 can seal the liquid outlet hole 601.

[0042] Furthermore, two support rods 7 arranged symmetrically front and back are provided at the top of the bottom plate 1 and near the right side. An arc-shaped clamping plate 70 is provided at the top of the support rod 7. The circular tube 60 can be clamped on the two arc-shaped clamping plates 70. When moving the device, the support rod 7 plays a role in supporting and fixing the conveying component 6, facilitating the storage of the conveying component 6.

[0043] When the root nutrient delivery device of this embodiment is in use, first, move the device to the tree that needs fertilization. Through the rollers 2 and the push rod 3 on the bottom plate 1, the entire device can be easily moved to a suitable position. Then, check whether the nutrient solution in the liquid storage barrel 40 is sufficient. If necessary, add the nutrient solution through the liquid injection pipe 410 on the barrel cover 41, and ensure that the lid of the liquid injection pipe 410 is tightened after adding the liquid to prevent impurities from entering. After determining the position of the device, insert the circular tube 60 of the delivery component 6 into the soil. The design of the insertion needle 61 of the circular tube enables the circular tube 60 to be smoothly inserted into the soil until the liquid outlet hole 601 is close to the root of the tree. Then, rotate the threaded rod 63 in the reverse direction, so that the threaded rod 63 drives the connecting rod 64 and the cylindrical piston 65 to move upward, thereby opening the liquid outlet hole 601. Then, start the pump body 5. The pump body will draw out the nutrient solution in the liquid storage barrel 40 through the liquid extraction pipe 50 and transport it to the circular tube 60 through the liquid delivery hose 51. After the nutrient solution enters the circular tube 60, the nutrient solution is introduced into the liquid outlet channel 651 from multiple liquid guiding inclined grooves 650, and finally output from the liquid outlet channel 651 to the lower part of the cylindrical piston 65, so that the nutrient solution can be output from the liquid outlet hole 601 to the root of the tree, ensuring that the nutrient solution can be directly delivered to the root part. After a single nutrient solution delivery operation, rotate the threaded rod 63 in the forward direction, driving the connecting rod 64 and the cylindrical piston 65 to move downward. When the bottom of the cylindrical piston abuts against the top of the insertion needle 61, the liquid outlet hole 601 will be blocked, preventing soil from entering the inside of the circular tube and further preventing the blockage of the liquid outlet hole. In addition, to prevent the precipitation of the nutrient solution in the liquid storage barrel 40, the motor 42 can be started. The motor 42 will drive the stirring rod 44 connected to the rotating shaft 43 to rotate, thereby stirring the nutrient solution in the liquid storage barrel 40 to ensure its uniformity. After fertilization, pull out the delivery component 6 from the soil. For easy movement and storage, the delivery component 6 is clamped on the arc-shaped clamping plate 70 to ensure the effective fixation of the delivery component 6 when the device is moved. If it is necessary to empty the nutrient solution in the liquid storage barrel 40, it can be controlled through the drain pipe 400 with a valve. After emptying, the valve can be closed.
