[0002] As global climate change and water shortage problems intensify, water retainers, as an effective water-saving material, are increasingly used in agriculture and forestry. Water retainers can absorb and store water and slowly release it under drought conditions to improve the drought resistance of plants. However, the current traditional water retainer delivery methods mostly rely on manual operations, which have many disadvantages. On the one hand, manual delivery is inefficient and difficult to meet the needs of large areas of forest or farmland; on the other hand, manual operation is difficult to ensure the uniformity of water retainer delivery, which affects the full play of the water retainer effect.

[0026] As shown in the figure, a device for placing drought-resistant afforestation water-retaining agent includes a device bracket, a storage barrel, a drilling mechanism and a soil collecting mechanism.

[0027] The device bracket is the supporting base of the whole device, including the third support plate 103, the second support plate 102 and the first support plate 101 arranged in sequence from top to bottom. The third support plate 103 is fixedly connected to the second support plate 102 at the four corners of the bottom through the second column 105. This connection method ensures a stable vertical spacing between the third support plate 103 and the second support plate 102, and ensures the stability of the upper equipment installation. The second support plate 102 is fixedly connected to the first support plate 101 at the four corners of the bottom through the first column 104, which also maintains the stability of the overall structure. Universal wheels 106 are arranged at the four corners of the bottom of the first support plate 101, so that the whole device is easy to move and can be flexibly pushed to different forest planting areas for operation.

[0028] The device bracket provides a reliable installation support platform for the storage barrel, drilling mechanism, soil collection mechanism and other components, ensuring that the positions of the components are fixed during operation to avoid shaking or displacement that affects the work accuracy and efficiency. At the same time, the design of the universal wheel 106 gives the device good mobility and can adapt to complex and changeable forest terrain.

[0029] A control box 5 is provided on the third support plate 103 as the control center of the entire device, which is electrically connected to the stirring motor 205, the metering pump 6, the drilling motor 301, the multi-stage electric telescopic rod 305 and the vacuum pump 701 through wires to achieve centralized control and operation of various functions of the device.

[0030] The storage barrel is used to store the water-retaining agent after mixing with water. The storage barrel includes a storage barrel cover 201 and a storage barrel body 202 arranged on the third support plate 103. A material guide pipe 203 is arranged below the storage barrel body 202 to guide the water-retaining agent in the storage barrel to a specified position.

[0031] A stirring motor 205 is provided above the storage barrel cover 201 through a motor bracket 204, and an output shaft of the stirring motor 205 penetrates the storage barrel cover 201 and is connected to a stirring blade 206, so that the stirring motor 205 can drive the stirring blade 206 to rotate in the storage barrel. The stirring motor 205 and the stirring blade 206 work together to stir the water retaining agent during storage, thereby preventing the water retaining agent from settling and agglomerating, ensuring the uniformity of the water retaining agent, and improving the water retaining effect.

[0032] A metering pump 6 is provided at one end of the guide tube 203 near the barrel body 202 of the storage barrel. The metering pump 6 can accurately discharge the water-retaining agent from the storage barrel according to the set dosage, ensuring that the amount of water-retaining agent added to each planting pit is consistent to meet the needs of scientific afforestation.

[0033] The guide pipe 203 sequentially penetrates the second support plate 102 and the first support plate 101. The first elbow 107 is provided at one end of the guide pipe 203 that penetrates the first support plate 101. The first elbow 107 is provided with a water retaining agent outlet. An ultrasonic sensor is provided in the water retaining agent outlet. The ultrasonic sensor is used to detect whether the water retaining agent is discharged from the water retaining agent outlet, and provide a signal trigger basis for subsequent soil backfilling and other operations.

[0034] The material storage barrel is arranged on the third support plate 103, and is connected to the first curved pipe 107 through the material guide pipe 203 penetrating the lower support plate, thereby forming a complete water-retaining agent conveying path. The stirring motor 205 and the metering pump 6 are both electrically connected to the control box 5, and receive the instructions of the control box 5 to work, thereby realizing the automatic control of stirring and discharging.

[0035] The drilling mechanism includes a drilling motor 301 and a drill bit 302 arranged on the output shaft of the drilling motor 301. The drilling motor 301 is connected to a multi-stage electric telescopic rod 305 through a first connecting plate 303 and a second connecting plate 304. The other end of the multi-stage electric telescopic rod 305 passes through the first support plate 101 and is fixedly connected to the bottom of the second support plate 102. A drill hole matching the drill bit 302 is opened on the first support plate 101 to facilitate the downward drilling operation of the drill bit.

[0036] The drilling motor 301 provides rotational power for the drill bit 302, so that the drill bit 302 can drill into the soil to perform drilling operations to meet the needs of digging planting pits before the water retaining agent is placed. The multi-stage electric telescopic rod 305 is responsible for controlling the up and down movement of the drilling motor 301 and the drill bit 302, and can adjust the drilling depth according to actual needs. After the drilling is completed, the drilling motor 301 and the drill bit 302 are returned to their original positions to facilitate subsequent operations.

[0037] The soil collecting mechanism includes a soil collecting box 401 arranged on the second support plate 102 and a soil collecting cylinder 402 arranged on the first support plate 101, a soil discharge pipe 403 is arranged below the soil collecting box 401, and a negative pressure mechanism is arranged on the second support plate 102. The negative pressure mechanism includes a vacuum pump 701 and a negative pressure pipe 702. One end of the negative pressure pipe 702 is connected to the vacuum pump 701, and the other end of the negative pressure pipe 702 is connected to the soil collecting box 401.

[0038] The lower end of the soil discharge pipe 403 passes through the first support plate 101, and a second bend pipe 404 is provided at the through end of the soil discharge pipe 403. The second bend pipe 404 is provided with a soil backfill outlet, and a capacitive sensor is provided in the soil backfill outlet. The bending angles of the first bend pipe 107 and the second bend pipe 404 are equal, and the openings of the first bend pipe 107 and the second bend pipe 404 are arranged opposite to each other, and the heights of the first bend pipe 107 and the second bend pipe 404 from the ground are equal.

[0039] The soil collecting mechanism cooperates closely with the drilling mechanism, and the soil collecting tube 402 is arranged around the drilling mechanism to collect the soil generated by the drilling in time. The soil collecting box 401 is installed on the second support plate 102, and is connected to the vacuum pump 701 through the negative pressure mechanism to realize the negative pressure collection of soil. The soil discharge pipe 403 runs through the first support plate 101 to connect the soil collecting box 401 and the second curved pipe 404, forming a complete soil collection and backfilling path, and the vacuum pump 701 and the capacitive sensor are electrically connected to the control box 5 and are uniformly controlled by the control box 5.

[0040] A tongue piece 405 is provided inside the end of the soil discharge pipe 403 close to the soil collecting box 401. A screen 406 is provided inside the soil collecting cylinder 402, and a multi-stage electric telescopic rod 305 and a drilling mechanism are provided inside the screen 406. A soil collecting ring pipe 407 is provided outside the soil collecting cylinder 402, and the soil collecting ring pipe 407 is connected to the soil collecting cylinder 402 through four symmetrically arranged connecting pipes 408, and the soil collecting ring pipe 407 is connected to the soil collecting box 401 through a soil collecting pipe 409.

[0041] The soil collecting cylinder 402 and the screen 406 are fixedly arranged on the first support plate 101. The diameter of the soil collecting cylinder 402 is larger than the diameter of the screen 406, and the diameter of the screen 406 is larger than the diameter of the drill hole.

[0042] The soil collecting cylinder 402 adopts a well-designed large-diameter structure, and its diameter is significantly larger than the diameter of the screen 406. This design can efficiently receive a large amount of soil delivered by the spiral structure of the drill bit during the drilling operation, ensuring that the soil produced by the drilling can be fully collected without spilling and affecting the working environment. The screen 406 is cleverly placed inside the soil collecting cylinder 402. Although its diameter is smaller than the soil collecting cylinder 402, it is larger than the diameter of the hole drilled by the drill bit 302 in the drilling mechanism. This arrangement allows the screen 406 to properly screen the soil delivered from the drilling hole, effectively intercept larger impurities such as soil clods and stones, and only allow soil particles with appropriate particle sizes to pass through, providing a strong guarantee for the uniformity and smoothness of the subsequent soil backfilling, thereby ensuring the operating quality and efficiency of the entire drought-resistant afforestation water-retaining agent delivery device.

[0043] In the actual drilling process, the soil drilled out by the drilling mechanism is transported to the soil collecting barrel 402 through the spiral structure of the drill bit, and the soil collecting barrel 402 serves as a temporary soil collection. The screen 406 performs preliminary screening of the soil, filters out larger soil blocks, stones and other impurities, and ensures that the collected soil has a relatively uniform texture, which is convenient for subsequent backfilling operations. The soil collecting ring pipe 407 and the connecting pipe 408 connect the soil collecting barrel 402 to the soil collecting box 401. Under the negative pressure generated by the vacuum pump 701, the soil in the soil collecting barrel 402 is sucked into the soil collecting box 401 for storage. When soil backfilling is required, the tongue 405 falls to open the soil discharge pipe 403 channel, and the soil is discharged from the soil backfill outlet through the soil discharge pipe 403 and the second bend pipe 404, and the planting pit is backfilled and covered with a water retaining agent. The capacitive sensor is used to detect whether the soil is discharged from the soil backfill outlet, so as to determine whether the backfilling operation is completed.

[0044] Baffles 108 are fixedly arranged around the third support plate 103. Baffles 108 can effectively prevent the water-retaining agent from leaking out of the storage barrel during operation. Once the water-retaining agent leaks out from the joints of the components, baffles 108 can intercept it to prevent the water-retaining agent from flowing to various parts of the device and avoid waste of water-retaining agent. At the same time, it also prevents a series of adverse consequences such as corrosion of device components and pollution of the surrounding environment caused by water-retaining agent leakage, ensuring that the device is always in good operating condition and ensuring the smooth progress of the entire drought-resistant afforestation water-retaining agent placement operation.

[0045] A handrail 109 is provided on one side of the baffle 108 to facilitate the operator to push the device to move in the forest, providing convenience for the mobile operation of the device. The control box 5 is provided with a stirring button, a start button, a drill down indicator light, a negative pressure soil collection indicator light, a drill up indicator light, a water replenishment agent discharge indicator light, and a soil backfill indicator light.

[0046] The stirring button is used to control the start and stop of the stirring motor 205, so as to realize the stirring operation of the water retaining agent in the storage barrel. After the start button is pressed, the device is powered on as a whole, and each component starts to work according to the preset process. The corresponding indicator lights up, such as the drill head downward indicator lights up, indicating that the multi-stage electric telescopic rod 305 drives the drilling motor 301 to start drilling downward, and the negative pressure soil collection indicator lights up, indicating that the vacuum pump 701 starts to collect soil. These indicator lights provide the operator with intuitive feedback on the working status of the device, which is convenient for monitoring the operation process.

[0047] The indicator light of the drill head up indicates the return process of the drilling motor 301, the indicator light of the water replenishment agent discharge indicates that the metering pump 6 starts to discharge the water retaining agent, and the indicator light of the soil backfill indicates that the soil backfill operation begins. The operator can judge the operation of the device according to the indicator light status, find abnormalities in time and deal with them. The control box 5 is electrically connected to each electrical component, and accurately controls the action of each component according to the button instructions pressed by the operator and the signals fed back by each sensor, so as to realize the automatic operation of the entire device.

[0048] The present invention also provides a method for using a device for delivering a drought-resistant afforestation water-retaining agent, comprising the following steps: S1. Water-retaining agent preparation: After the water-retaining agent mixed with water is poured into the storage barrel, the storage barrel cover 201 is covered. The water-retaining agent and water are mixed to form a gel-like substance, which has good water-retaining performance and can provide a continuous water supply for the roots of trees in arid environments. Covering the barrel cover can prevent the water-retaining agent from volatilizing and being contaminated by impurities, thereby ensuring its stable performance.

[0049] Mixing operation: Press the stirring button on the control box 5 to start the stirring motor 205 to start stirring, driving the stirring blades 206 to rotate in the storage barrel. During the stirring process, the stirring blades 206 continuously turn the water-retaining agent to make its internal components more uniform, avoid precipitation and stratification of the water-retaining agent, ensure the consistency of the performance of the water-retaining agent discharged subsequently, and improve the water-retaining effect; after the stirring is completed, press the stirring button again to reset, the device stops stirring, and prepares to enter the next stage.

[0050] S2. Equipment movement and positioning: The device is pushed to the side of the trees where the water retaining agent needs to be placed. Since the universal wheels 106 are provided at the bottom of the device, the operator can easily push the device to move in the forest through the handrails 109, and stop when it reaches a suitable position near the target trees, so as to prepare for positioning for drilling and water retaining agent placement operations.

[0051] S3, device startup: Press the start button of the control box 5 to power on the device. At this time, the drill head downward indicator light is on and the negative pressure soil collection indicator light is on, indicating that the device has entered the drilling and soil collection process. The multi-stage electric telescopic rod 305 begins to extend under the command of the control box 5, driving the drilling motor 301 downward. At the same time, the drilling motor 301 starts, driving the drill bit 302 to rotate at a high speed, and the drill bit 302 begins to drill the target point.

[0052] S4, drilling process: The drill bit 302 goes down to drill a hole at the target point. The drill bit 302 drills into the soil during the rotation process. As the multi-stage electric telescopic rod 305 continues to extend, the drilling depth gradually increases. The drilled soil is transported upward to the soil collecting cylinder 402 through the spiral structure of the drill bit. The bottom opening on the side of the soil collecting cylinder 402 is connected to the soil collecting box 401 through the soil collecting ring pipe 407 and the soil discharge pipe 403. At the same time, the vacuum pump 701 is started to form a negative pressure environment in the negative pressure pipe 702 and the soil collecting box 401. Under the action of negative pressure, the vacuum pump 701 sucks the soil in the soil collecting cylinder 402 into the soil collecting box 401 for storage, completing the soil collection work during the drilling process. The screen 406 screens the soil during the soil collection process to ensure that the soil entering the soil collecting box has a relatively uniform texture, which is convenient for subsequent backfilling operations.

[0053] S5, return to the original position after drilling: When the drilling reaches the set depth, the depth sensor installed in the drilling mechanism or a related position feeds back the signal to the control box 5. After receiving the signal, the control box 5 controls the drill head down indicator to turn off, the negative pressure soil collection indicator to turn off, and the drilling motor 301 stops rotating, the drill head up indicator lights up, and the multi-stage electric telescopic rod 305 retracts to drive the drilling motor 301 and the drill bit 302 back to the initial position, ready for the water retaining agent placement operation.

[0054] S6. Water-retaining agent placement: After the drilling motor 301 returns to its position, the control box 5 receives the return signal, controls the water-replenishing agent discharge indicator to light up, and the drill head upward indicator to go out. At this time, the metering pump 6 starts under the command of the control box 5, and discharges a fixed amount of water-retaining agent from the storage cylinder according to the preset dosage. The water-retaining agent passes through the guide pipe 203 and the water-retaining agent discharge outlet of the first bend pipe 107 and falls into the pre-drilled pit. The ultrasonic sensor in the water-retaining agent discharge outlet detects the discharge of the water-retaining agent in real time. When the discharge of the water-retaining agent is detected, the signal is fed back to the control box 5.

[0055] S7, backfill start: After the ultrasonic sensor in the water retaining agent outlet detects that the water retaining agent is discharged, the control box 5 controls the soil backfill indicator to light up and the water replenishing agent discharge indicator to go out. At the same time, the vacuum pump 701 stops working, and the tongue piece 405 in the soil discharge pipe 403 falls down, opening the soil discharge pipe 403 channel. Under the action of gravity, the soil stored in the soil collecting box 401 is discharged from the soil backfill outlet through the soil discharge pipe 403 and the second bend pipe 404 and backfilled into the pit, thereby achieving the covering and backfilling operation of the water retaining agent in the planting pit.

[0056] S8, backfill completion detection: The capacitive sensor in the soil backfill outlet detects the soil discharge in real time. When the soil discharge is detected and reaches a certain amount (the detection threshold can be set according to actual needs), it indicates that the soil backfill operation is completed.

[0057] At this time, the capacitive sensor feeds back the signal to the control box 5.
