Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a device for dispensing a drought-resistant afforestation water-retaining agent and its method of use. Background Technology

[0002] With the increasing severity of global climate change and water scarcity, water-retaining agents, as an effective water-saving material, are being used more and more widely in agriculture and forestry. Water-retaining agents can absorb and store water, releasing it slowly under drought conditions, thereby improving the drought resistance of plants. However, current traditional methods of applying water-retaining agents mostly rely on manual operation, which has many drawbacks. On the one hand, manual application is inefficient and cannot meet the needs of large areas of forest land or farmland; on the other hand, manual operation makes it difficult to ensure the uniformity of water-retaining agent application, affecting the full effectiveness of the agent. Furthermore, manual application is labor-intensive, increasing labor costs.

[0003] Furthermore, existing application devices have revealed a series of problems in practical applications. During application, the water-retaining agent is prone to clumping, which not only affects the smoothness of application but also leads to uneven distribution of the water-retaining agent in the soil, reducing its water-retaining effect. Moreover, the existing devices do not adequately treat the soil after drilling, resulting in incomplete soil backfilling, which affects soil structure and the plant growth environment.

[0004] Therefore, developing an automated and efficient water-retaining agent dispensing device to achieve uniform dispensing of the water-retaining agent, automatic soil backfilling, and intelligent control of the equipment has become an urgent task to meet the needs of modern agriculture and forestry development.

[0045] As shown in the figure, a device for dispensing drought-resistant afforestation water-retaining agent includes a device support, a storage cylinder, a drilling mechanism, and a soil collection mechanism.

[0046] The support frame serves as the foundation for the entire device, comprising a third support plate 103, a second support plate 102, and a first support plate 101 arranged sequentially from top to bottom. The third support plate 103 is fixedly connected to the second support plate 102 at its four bottom corners via second columns 105. This connection method ensures a stable vertical distance between the third support plate 103 and the second support plate 102, guaranteeing the stability of the equipment installation above. The second support plate 102 is fixedly connected to the first support plate 101 at its four bottom corners via first columns 104, similarly maintaining the overall structural stability. The first support plate 101 is equipped with casters 106 at its four bottom corners, facilitating the movement of the entire device and allowing it to be flexibly pushed to different forest planting areas for operation.

[0047] The device support frame provides a reliable mounting platform for components such as the storage cylinder, drilling mechanism, and soil collection mechanism, ensuring that each component remains in a fixed position during operation and preventing swaying or displacement from affecting working accuracy and efficiency. Meanwhile, the 106 casters give the device excellent mobility, enabling it to adapt to complex and varied forest terrain.

[0048] The control box 5 is installed on the third support plate 103, which serves as the control center of the entire device. It is electrically connected to the stirring motor 205, metering pump 6, drilling motor 301, multi-stage electric telescopic rod 305 and vacuum pump 701 through wires, so as to realize centralized control and operation of various functions of the device.

[0049] The storage cylinder is used to store the water-retaining agent after mixing with water. The storage cylinder includes a storage cylinder cover 201 and a storage cylinder body 202 disposed on the third support plate 103. A guide pipe 203 is disposed below the storage cylinder body 202 to guide the water-retaining agent in the storage cylinder to a designated location.

[0050] A stirring motor 205 is mounted above the storage cylinder cover 201 via a motor bracket 204. The output shaft of the stirring motor 205 passes through the storage cylinder cover 201 and is connected to stirring blades 206, enabling the stirring motor 205 to drive the stirring blades 206 to rotate inside the storage cylinder. The stirring motor 205 and the stirring blades 206 work together to stir the water-retaining agent during storage, preventing sedimentation and clumping, ensuring the uniformity of the water-retaining agent, and improving the water retention effect.

[0051] A metering pump 6 is installed at one end of the feed pipe 203 near the storage cylinder 202. The metering pump 6 can accurately discharge the water-retaining agent from the storage cylinder according to the set dosage, ensuring that the amount of water-retaining agent added to each planting pit is consistent, thus meeting the needs of scientific afforestation.

[0052] The feed pipe 203 passes sequentially through the second support plate 102 and the first support plate 101. A first bend 107 is provided at one end of the feed pipe 203 that passes through the first support plate 101. The first bend 107 has a water-retaining agent outlet, and an ultrasonic sensor is installed inside the water-retaining agent outlet. The ultrasonic sensor is used to detect whether the water-retaining agent is discharged from the outlet, providing a signal trigger for subsequent soil backfilling and other operations.

[0053] The storage cylinder is mounted on the third support plate 103 and is connected to the first bend pipe 107 via the guide pipe 203, which passes through the lower support plate to form 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 operate according to the instructions of the control box 5 to realize the automated control of stirring and discharging.

[0054] The drilling mechanism includes a drilling motor 301 and a drill bit 302 mounted on the output shaft of the drilling motor 301. The drilling motor 301 is connected to a multi-stage electric telescopic rod 305 via a first connecting plate 303 and a second connecting plate 304. The other end of the multi-stage electric telescopic rod 305 passes through a first support plate 101 and is fixedly connected to the bottom of the second support plate 102. The first support plate 101 has a drill hole that matches the drill bit 302 to facilitate the downward drilling operation of the drill bit.

[0055] The drilling motor 301 provides rotational power to the drill bit 302, enabling it to drill into the soil to meet the excavation requirements of the planting pit before the application of the water-retaining agent. The multi-stage electric telescopic rod 305 controls the up-and-down movement of the drilling motor 301 and the drill bit 302, allowing adjustment of the drilling depth according to actual needs. After drilling is completed, the drilling motor 301 and the drill bit 302 are returned to their original positions for easy follow-up operations.

[0056] The soil collection mechanism includes a soil collection box 401 mounted on the second support plate 102 and a soil collection cylinder 402 mounted on the first support plate 101. A soil discharge pipe 403 is provided below the soil collection box 401. A negative pressure mechanism is provided 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 collection box 401.

[0057] The lower end of the soil discharge pipe 403 passes through the first support plate 101. A second bend 404 is provided at the through end of the soil discharge pipe 403. The second bend 404 is provided with a soil backfill discharge outlet. A capacitive sensor is provided inside the soil backfill discharge outlet. The bending angles of the first bend 107 and the second bend 404 are equal. The openings of the first bend 107 and the second bend 404 are opposite to each other. The heights of the first bend 107 and the second bend 404 from the ground are equal.

[0058] The soil collection mechanism works closely with the drilling mechanism. The soil collection cylinder 402 is positioned around the drilling mechanism to collect soil generated during drilling. The soil collection box 401 is mounted on the second support plate 102 and connected to the vacuum pump 701 via a negative pressure mechanism to achieve negative pressure soil collection. The soil discharge pipe 403 passes through the first support plate 101, connecting the soil collection box 401 and the second bend pipe 404, forming a complete soil collection and backfilling path. The vacuum pump 701 and the capacitive sensor are both electrically connected to the control box 5 and are under its unified control.

[0059] The soil discharge pipe 403 has a tongue 405 inside the end near the soil collection box 401. The soil collection cylinder 402 has a screen 406 inside, and a multi-stage electric telescopic rod 305 and a drilling mechanism inside the screen 406. The soil collection ring pipe 407 is installed on the outside of the soil collection cylinder 402. The soil collection ring pipe 407 is connected to the soil collection cylinder 402 through four symmetrically arranged connecting pipes 408. The soil collection ring pipe 407 is connected to the soil collection box 401 through the soil collection pipe 409.

[0060] The soil collecting cylinder 402 and the screen 406 are fixedly installed 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 borehole.

[0061] The soil collection cylinder 402 features a meticulously designed large-diameter structure, significantly larger than the screen 406. This design efficiently collects the large volume of soil transported by the drill bit's spiral structure during drilling operations, ensuring that the soil generated during drilling is fully collected and prevents spillage that could affect the working environment. The screen 406 is cleverly positioned inside the soil collection cylinder 402. While its diameter is smaller than the cylinder itself, it is larger than the diameter of the borehole drilled by the drill bit 302. This arrangement allows the screen 406 to precisely sieve the soil transported from the borehole, effectively intercepting larger clods, stones, and other impurities, allowing only appropriately sized soil particles to pass through. This provides a strong guarantee for the uniformity and smoothness of subsequent soil backfilling, thereby ensuring the overall operational quality and efficiency of the drought-resistant afforestation water-retaining agent application device.

[0062] During the actual drilling process, the soil drilled by the drilling mechanism is transported to the soil collection cylinder 402 via the drill bit spiral structure. The soil collection cylinder 402 serves as a temporary soil collection point. A screen 406 performs preliminary sieving of the soil, filtering out larger clods, stones, and other impurities to ensure a relatively uniform soil texture for subsequent backfilling. The soil collection ring pipe 407 and connecting pipe 408 connect the soil collection cylinder 402 to the soil collection box 401. Under the negative pressure generated by the vacuum pump 701, the soil in the soil collection cylinder 402 is drawn into the soil collection box 401 for storage. When backfilling is required, the tongue 405 drops to open the discharge pipe 403, allowing soil to be discharged through the discharge pipe 403 and the second bend pipe 404 from the soil backfill outlet, facilitating the backfilling and covering of the planting pit with a water-retaining agent. A capacitive sensor detects whether soil is discharged from the soil backfill outlet, thus determining whether the backfilling operation is complete.

[0063] The third support plate 103 is fixedly equipped with baffles 108 around its perimeter. The baffles 108 effectively prevent leakage of the water-retaining agent from the storage cylinder during operation. If the water-retaining agent leaks from the joints of any component, the baffles 108 can intercept it, preventing it from flowing freely throughout the device and thus avoiding waste. Simultaneously, it also eliminates a series of adverse consequences that could result from water-retaining agent leakage, such as corrosion of device components and pollution of the surrounding environment, ensuring that the device is always in good operating condition and guaranteeing the smooth progress of the entire drought-resistant afforestation water-retaining agent application operation.

[0064] A handrail 109 is provided on one side of the baffle 108 to facilitate the operator's movement of the device in the woodland, providing convenience for the device's mobile operation. The control box 5 is equipped with a stirring button, a start button, a drill bit down indicator light, a negative pressure soil collection indicator light, a drill bit up indicator light, a water-discharging agent indicator light, and a soil backfilling indicator light.

[0065] The stirring button controls the start and stop of the stirring motor 205, enabling the stirring of the water-retaining agent in the storage cylinder. When the start button is pressed, the entire device is powered on, and each component begins operating according to the preset procedure. Corresponding indicator lights illuminate; for example, the drill bit descent indicator light illuminates to indicate that the multi-stage electric telescopic rod 305 drives the drilling motor 301 to descend and begin drilling; the negative pressure soil collection indicator light illuminates to indicate that the vacuum pump 701 has started to collect soil. These indicator lights provide operators with intuitive feedback on the device's operating status, facilitating monitoring of the work process.

[0066] The drill bit's upward indicator light illuminates to indicate the return process of the drill pit motor 301; the water-retaining agent discharge indicator light illuminates to indicate that the metering pump 6 has started discharging water-retaining agent; and the soil backfilling indicator light illuminates to indicate that soil backfilling has begun. Operators can judge the device's operating status based on the indicator light status, promptly identify and address any abnormalities. The control box 5 is electrically connected to all electrical components and precisely controls the actions of each component based on the button commands pressed by the operator and the signals fed back from each sensor, achieving automated operation of the entire device.

[0067] The present invention also provides a method for using a device for dispensing a water-retaining agent for drought-resistant afforestation, comprising the following steps:

[0068] S1. Preparation of water-retaining agent:

[0069] After pouring the water-retaining agent into the storage cylinder, cover the cylinder with the cap 201. The water-retaining agent and water mix to form a gel-like substance with good water retention properties. It can provide a continuous water supply to the roots of trees in arid environments. Covering the cylinder with the cap can prevent the water-retaining agent from evaporating and becoming contaminated with impurities, thus ensuring its stable performance.

[0070] Stirring operation:

[0071] Press the stirring button on control box 5 to start stirring motor 205, which drives stirring blade 206 to rotate in storage cylinder. During stirring, stirring blade 206 continuously agitates the water-retaining agent to make its internal composition more uniform, avoid sedimentation and stratification of the water-retaining agent, ensure that the performance of the water-retaining agent discharged later is consistent, and improve the water retention effect. After stirring is completed, press the stirring button again to reset, the device stops stirring, and prepares to enter the next stage.

[0072] S2. Equipment movement and positioning:

[0073] The device is pushed to the side of the trees where the water-retaining agent needs to be applied. Since the bottom of the device is equipped with casters 106, the operator can easily push the device to move in the forest through the handle 109. After reaching a suitable position near the target trees, the device is stopped to prepare for drilling and water-retaining agent application.

[0074] S3, Device Start-up:

[0075] Press the start button on control box 5 to power on the device. At this time, the drill bit descent indicator light and the negative pressure soil collection indicator light will illuminate, indicating that the device has entered the drilling and soil collection operation process. Under the command of control box 5, the multi-stage electric telescopic rod 305 begins to extend, driving the drilling pit motor 301 to descend. At the same time, the drilling pit motor 301 starts, driving the drill bit 302 to rotate at high speed, and the drill bit 302 begins to drill at the target point.

[0076] S4. Drilling process:

[0077] Drill bit 302 descends to drill a hole at the target point. As it rotates, it penetrates the soil. With the continuous extension of the multi-stage electric telescopic rod 305, the drilling depth gradually increases. The drilled soil is transported upwards through the drill bit's spiral structure to the soil collection cylinder 402. The bottom side opening of the soil collection cylinder 402 connects it to the soil collection box 401 via a soil collection ring pipe 407 and a soil discharge pipe 403. Simultaneously, the vacuum pump 701 starts, creating a negative pressure environment within the negative pressure pipe 702 and the soil collection box 401. Under this negative pressure, the vacuum pump 701 draws the soil from the soil collection cylinder 402 into the soil collection box 401 for storage, completing the soil collection process during drilling. The screen 406 sieves the soil during collection to ensure a relatively uniform soil texture entering the soil collection box, facilitating subsequent backfilling.

[0078] S5. Drilling ends and the machine returns to its original position:

[0079] Once the borehole reaches the set depth, the depth sensor installed on the drilling mechanism or related location sends a signal back to the control box 5. Upon receiving the signal, the control box 5 turns off the drill bit down indicator light and the negative pressure soil collection indicator light. Simultaneously, the drilling motor 301 stops rotating, the drill bit up indicator light illuminates, and the multi-stage electric telescopic rod 305 retracts, driving the drilling motor 301 and drill bit 302 back to their initial positions, ready for the water-retaining agent application operation.

[0080] S6. Addition of water-retaining agent:

[0081] After the drilling motor 301 returns to its original position, the control box 5 receives the return signal, controls the water-retaining agent indicator light to illuminate, and the drill bit upward indicator light to turn off. At this time, the metering pump 6 starts under the command of the control box 5, discharging a quantitative amount of water-retaining agent from the storage cylinder according to the preset dosage. The water-retaining agent falls into the pre-drilled pit through the guide pipe 203 and the water-retaining agent outlet of the first bend pipe 107. The ultrasonic sensor in the water-retaining agent outlet detects the discharge of the water-retaining agent in real time. When the discharge of the water-retaining agent is detected, a signal is fed back to the control box 5.

[0082] S7. Backfilling Start:

[0083] After the ultrasonic sensor inside the water-retaining agent discharge port detects the discharge of the water-retaining agent, the control box 5 activates the soil backfill indicator light and deactivates the water-retaining agent discharge indicator light. Simultaneously, the vacuum pump 701 stops operating, and the tongue 405 inside the soil discharge pipe 403 descends, opening the passage of the soil discharge pipe 403. The soil stored in the soil collection box 401, under gravity, is discharged through the soil discharge pipe 403 and the second bend pipe 404 from the soil backfill discharge port and backfilled into the pit, thus achieving the covering and backfilling operation of the water-retaining agent in the planting pit.

[0084] S8. Backfilling completion inspection:

[0085] The capacitive sensor inside the soil backfill outlet monitors the soil discharge in real time. When soil discharge is detected and reaches a certain amount (the detection threshold can be set according to actual needs), it indicates that the soil backfilling operation is complete.

[0086] At this point, the capacitive sensor sends a signal back to control box 5. Upon receiving the signal, control box 5 turns off the soil backfill indicator light, ending the entire process. Workers can then press the stop button on the control box to move the device to the next target location and repeat the above steps to continue applying the drought-resistant afforestation water-retaining agent.

[0087] Therefore, the present invention employs the above-mentioned device and method for dispensing a water-retaining agent for drought-resistant afforestation, which improves the uniformity and efficiency of water-retaining agent dispensing, reduces human intervention, is suitable for large-area forest land, and has broad promotion value.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
