Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and in particular to a fertilization device, especially a high-efficiency fertilization device for Torreya grandis in mountainous environments. Background Technology

[0002] Torreya grandis, a precious dried fruit and economic tree species unique to my country, is widely planted in the hilly and mountainous areas of Zhejiang, Fujian, and Anhui provinces. Traditional fertilization methods face three core problems: 1) Terrain limitations: Sloping mountainous areas make mechanized operations difficult. Existing fertilizer application equipment suffers from problems such as unstable center of gravity and poor climbing ability, resulting in a fertilizer coverage rate of less than 30%. 2) Fertilizer loss: Conventional methods of directly spreading fertilizer on the ground by hand are easily washed away by rainwater, and the nitrogen utilization rate is only 40%-45%, which is significantly lower than that in plains areas; 3) Labor costs: Manual fertilization is inefficient, requiring 2-3 man-days per acre, accounting for more than 35% of the total planting cost.

[0003] Therefore, there is an urgent need to develop a special fertilization device for mountainous Torreya grandis that is suitable for mountainous terrain, prevents fertilizer from being washed away by rainwater after fertilization, and is highly efficient and reduces planting costs, so as to break through the bottleneck of existing technology.

[0004] Chinese utility model patent CN 215223077 U discloses a quantitative fertilization device for Torreya grandis forests. The device includes a base, a feeding box fixedly connected to the upper end of the base, a feeding pipe fixedly connected to the upper end of the feeding box, a chassis fixedly connected to the upper end of the feeding pipe, and a feeding hopper fixedly connected to the upper end of the chassis. It also includes a quantitative component; the quantitative component controls the amount of fertilizer applied during fertilization. The quantitative component is mounted on the feeding box and includes a control panel, which is fixedly installed on the feeding box. A display screen is fixedly mounted on the control panel, and control buttons are fixedly mounted at the lower end of the display screen. A processor is fixedly mounted inside the control panel, and a quantitative valve is fixedly mounted inside the feeding pipe. The display screen, control buttons, processor, and quantitative valve are electrically connected. A discharge hose is fixedly connected to the lower end of the feeding box, passing through the base and extending to the lower end of the base. A connecting plate is fixedly connected to the lower end of the discharge hose, and a discharge pipe is fixedly connected to the lower end of the discharge hose, passing through the connecting plate and extending to the lower end of the connecting plate. The device cannot be used in mountainous environments and has poor versatility. It can only be used by digging trenches on the side of the Torreya grandis tree and applying fertilizer in the trenches. It cannot be used directly under the Torreya grandis tree, resulting in low fertilizer absorption and utilization rates. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of the prior art and provide a high-efficiency fertilization device for Torreya grandis in mountainous environments that is suitable for mountainous terrain, avoids fertilizer loss due to rainwater after fertilization, and is highly efficient and reduces planting costs. It meets the needs of high efficiency, good fertilization effect and low planting cost for Torreya grandis in mountainous environments.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: This high-efficiency fertilization device for Torreya grandis in mountainous environments includes a chassis, with tracked wheels on both sides of the chassis. A power source for driving the tracked wheels is installed on the chassis. A support plate is fixed to the top of the chassis, and a Torreya grandis tree clamping and fertilization mechanism and a fertilizer granule conveying mechanism are installed on the support plate. The Torreya grandis tree clamping and fertilization mechanism includes a vertical plate hinged to the front end of the support plate, a mounting plate slidably connected to the vertical plate, a second drive motor installed on the vertical plate, a first transverse fixing block fixed on the mounting plate, a screw nut fixed on the first transverse fixing block, a screw that cooperates with the screw nut fixed on the shaft of the second drive motor, and a second transverse fixing block fixed on the vertical plate. A guide rod is fixed between the first horizontal fixing block and the bottom of the vertical plate. A guide sleeve that engages with the guide rod is fixed on the first horizontal fixing block. A horizontal block is fixed on the mounting plate. A first electric cylinder is provided on both the inner and outer sides of the side of the vertical plate. The bottom of the cylinder body of the two first electric cylinders is hinged to the support plate. The top of the piston rod of the two first electric cylinders is hinged to the vertical plate. A pair of symmetrically arranged clamping plates are slidably connected to the horizontal block. A pair of first compression springs for bringing the two clamping plates closer together are installed on the horizontal block. A pair of opposing suspension plates are fixed to the top of each of the two clamping plates. The four suspension plates are distributed at four corners. An elliptical rod is inserted into each suspension plate. A through hole is opened on the elliptical rod. A flat plate is fixed to the top of the elliptical rod. A plate, a flat plate, is equipped with a first hollow motor. A shaft is fixed to the hollow shaft of the first hollow motor, which is fitted into a through hole and extends into an elliptical rod. A discharge channel is opened on the shaft, and a discharge hole is provided at the bottom end of the discharge channel at the shaft. A spiral tunneling blade is installed at the shaft. A blocking block with a cross-section larger than the outer contour of the elliptical rod is fixed to the bottom end of the elliptical rod. A second compression spring is provided between the bottom surface of the suspension plate and the top surface of the blocking block, sleeved on the elliptical rod. The fertilizer granule conveying mechanism includes a feeding box, the bottom of which is connected to a discharge tray with a "V"-shaped cross-section. A first horizontally placed cylinder connected to the bottom surface of the discharge tray is fixed below the discharge tray. A device connected to the first horizontally placed cylinder is installed at the end of the first horizontally placed cylinder. A first vertical cylinder has a first downward tilting disc fixed at its top, which communicates with the first vertical cylinder. A first downward tilting cylinder is fixed at its end, which communicates with the first downward tilting disc. Spiral propulsion blades are installed inside the first horizontal cylinder, the first vertical cylinder, and the first downward tilting cylinder. A third drive motor for driving the rotation of each spiral propulsion blade is installed on each of the first horizontal cylinder, the first vertical cylinder, and the first downward tilting cylinder. A discharge pipe is installed at the end of the first downward tilting cylinder. A bracket is fixed on each suspension plate. A discharge pipe is fixed on the bracket and inserted into the hollow shaft of the first hollow motor. A discharge hose is installed between each discharge pipe and the discharge tube.The chassis, track wheels, and power source serve several purposes. The track wheels offer a larger contact area, making them more suitable for mountainous environments, providing greater stability, and ensuring smoother operation. The Torreya grandis tree clamping and fertilizing mechanism clamps the trees according to their diameter, automatically controlling the distance between the fertilizer outlet and the tree. This ensures the fertilizer is applied precisely to the tree, maximizing fertilizer utilization and significantly reducing production costs. The working principle of this mechanism involves adjusting the angle of the two clamping plates to ensure they are parallel to the ground. Then, the two clamping plates are moved, and the pressure from the Torreya grandis tree causes the clamping plates to open and simultaneously compress the two first compression springs, storing energy. The clamping plates continue to move forward until the four shafts are positioned around the Torreya grandis tree trunk. Next, the clamping plates are moved downwards. Due to the slope of the mountainous terrain, each shaft first touches the mountain surface, and the movement of the elliptical rods compresses the second compression springs, storing energy. This causes each shaft to touch the ground at varying heights according to the terrain. Subsequently, the first hollow motors are started, driving the shafts and the spiral tunneling blades on the shafts to rotate, simultaneously driving the mounting plates. The downward movement causes the edges of each spiral excavator blade to rotate and move downward, thus drilling a pit in the ground. At this point, fertilizer granules fall through the discharge pipe and then through the hollow shaft of the first hollow motor to the discharge channel and finally to the discharge hole, perfectly achieving the function of simultaneously excavating and fertilizing. After fertilization, the shafts can be moved upward. The function of the fertilizer granule conveying mechanism here is to efficiently transport fertilizer granules to the Torreya grandis tree clamping fertilization mechanism for fertilization. The working principle of the fertilizer granule conveying mechanism is as follows: fertilizer granules in the holding box slide down through the collection action of the discharge plate to the first... At the horizontally placed cylinder, synchronous spiral propulsion blades push fertilizer granules to the first vertically placed cylinder. Then, the spiral propulsion blades inside the first vertical cylinder lift the fertilizer granules and guide them quickly to the first downwardly tilted cylinder via the first downwardly tilted disc. The spiral propulsion blades inside the first downwardly tilted cylinder then evenly deliver the fertilizer granules to the discharge pipe, and finally deliver them to the discharge cylinder via the discharge hose. Here, the first hollow motor is a motor with a hollow shaft, which is an existing product on the market. Products from companies such as HIWIN Technologies (China) Co., Ltd. and Jiangsu Lailite Technology Co., Ltd. can be selected.

[0007] Further improvements include the addition of a pair of opposing wheels rotatably connected to the center of each of the two clamping plates. The wheels have a diameter larger than the plate thickness, and the four wheels are arranged in a square pattern on the inner side of the suspension plate. Each wheel's outer contour is ball-jointed with a set of ball bearings. The wheels' function is to allow them to roll and engage with the trunk of the Torreya grandis tree, maintaining a reasonable distance between the axles, the auger blades, and the tree (thus ensuring a suitable fertilization distance between the four corner axles and the trunk, improving fertilizer utilization). This design is suitable for drilling and fertilizing Torreya grandis trees of different diameters. The ball bearings prevent direct sliding friction between the wheels and the trunk surface as the wheels move downwards, thus avoiding wheel damage. This not only improves the smoothness of downward movement and prevents jamming but also protects the wheels and extends their lifespan.

[0008] Further improvements include the provision of a self-lubricating layer on the inner walls of the first horizontal cylinder, the first vertical cylinder, the first downward-sloping disk, and the first downward-sloping cylinder. The function of this self-lubricating layer is to ensure a high degree of contact between the spiral propulsion blades and the inner walls of these cylinders, preventing gaps that could cause fertilizer particles to become stuck and hinder the spiral propulsion blades' rotation. The self-lubricating layer on the inner wall of the first downward-sloping disk also allows for faster fertilizer particle descent and prevents particle accumulation. This self-lubricating layer is made of tin bronze.

[0009] Further improvements include the installation of a fertilizer granule equal-division distributor on the discharge pipe; the fertilizer granule equal-division distributor includes a housing fixed on the discharge pipe, a second hollow motor fixed inside the housing, four discharge pipes arranged in a four-corner pattern fixed on the housing, a bent pipe on the housing, the inlet end of the bent pipe fixed at the hollow shaft below the second hollow motor, the outlet end of the bent pipe matched with any one of the discharge pipes, the hollow shaft above the second hollow motor cooperated with the discharge pipe, and each discharge hose was assembled with each discharge pipe respectively. The function of the fertilizer granule distributor here is to evenly distribute fertilizer granules to each shaft and into the soil layer, thus avoiding the problem of inconsistent fertilizer granule quantities at each shaft's discharge hole. This prevents uneven nutrient distribution caused by some areas having more fertilizer granules than others in the four corners of the Torreya grandis tree. The working principle of the fertilizer granule distributor is as follows: When the fertilizer granules are conveyed to the discharge pipe by the fertilizer granule conveying mechanism, they are guided by the hollow shaft of the second hollow motor and then guided through the bending tube to one of the discharge pipes. From there, they are discharged through the discharge hose to a corresponding discharge pipe and finally through the discharge hole on the shaft. When feeding into the next discharge pipe, simply start the second hollow motor and rotate the bending tube 90 degrees, thus opening the discharge end of the bending tube. The fertilizer granules are fed into the next discharge pipe at the next angle. By repeating the above operation, the fertilizer granules can be fed into the four discharge pipes in equal portions, and the fertilizer granules can be discharged into the discharge ports on the four shafts in equal portions. This ensures that the fertilizer is applied evenly to the four corners of the Torreya grandis tree, resulting in more uniform nutrient application and better absorption by the Torreya grandis tree. Here, the second hollow motor can be a stepper motor or the rotation angle of the hollow shaft can be controlled by an angle controller to ensure that the discharge port of the bent tube is matched at the inlet of different discharge pipes at the same angle. When the outlet end of the bent tube rotates to the inlet end of the next discharge pipe, the third drive motor on the inlet end of the discharge pipe stops running. Only when the outlet end of the bent tube reaches the inlet end of the next discharge pipe and stops does the spiral propulsion blade on the first downward tilting cylinder start to transport fertilizer granules.

[0010] Further improvements include a handle fixed to the support plate, equipped with a left turn button, a right turn button, and a speed control knob. The handle facilitates control of the fertilizer applicator's forward direction; the left turn button turns the applicator to the left; the right turn button turns it to the right; and the speed control knob controls the applicator's speed. This speed control knob is a commercially available product and can be selected from companies such as Yueqing Omtel Electronic Technology Co., Ltd. and Suzhou Simai Instrument Technology Co., Ltd.

[0011] Further improvements include rear abutment components on both sides of the rear end of the support plate. Each rear abutment component includes a second electric cylinder, the tail end of which is hinged to the support plate. A third electric cylinder is located on the side of the second electric cylinder. First vertical plates are fixed to both sides of the top surface of the rear end of the support plate. The end of the third electric cylinder is hinged to the first vertical plate, and the end of the piston rod of the third electric cylinder is hinged to the cylinder body of the second electric cylinder. A first abutment block is fixed to the end of the piston rod of the second electric cylinder. The function of the rear abutment components is to provide support and resistance to the backward tilt of the fertilization device when fertilizing the Torreya grandis tree on an uphill slope, thus preventing the device from slipping during operation. The function of the second electric cylinder, third electric cylinder, and first abutment block is that when support for the backward tilt of the fertilization device is needed, only the third electric cylinder needs to be activated, causing the second electric cylinder to rotate at a suitable angle. Once rotated to the appropriate angle, the third electric cylinder can be activated, causing the first abutment block to embed into the soil layer, thus providing anti-slip resistance to the fertilization device (e.g., ...). Figure 13 (As shown).

[0012] Further improvements include front abutment components on both sides of the front end of the support plate; each front abutment component includes a fourth electric cylinder, the tail end of which is hinged to the support plate, and a fifth electric cylinder on its side. Second vertical plates are fixed to both sides of the top surface of the front end of the support plate. The end of the fifth electric cylinder is hinged to the second vertical plate, and the end of its piston rod is hinged to the cylinder body of the fourth electric cylinder. A second abutment block is fixed to the end of the piston rod of the fourth electric cylinder. The function of the front abutment components is to provide support and resistance to the forward tilt of the fertilization device when fertilizing Torreya grandis trees on a downhill slope, thus preventing the device from slipping during operation. The function of the fourth, fifth, and second abutment blocks is that when support for the forward tilt of the fertilization device is needed, only the fifth electric cylinder needs to be activated, causing the fourth electric cylinder to rotate at a suitable angle. Once rotated, the fourth electric cylinder can be activated, causing the second abutment block to embed into the soil, thus providing anti-slip resistance to the fertilization device (e.g., ...). Figure 14 (As shown).

[0013] Further improvements include the addition of vibrators fixed to both sides of the feeding tray. The purpose of these vibrators is to prevent fertilizer granules from getting stuck, ensuring smoother discharge.

[0014] Further improvements include the addition of guide plates fixed to the front ends of both clamping plates, with the two guide plates arranged in a horizontal "V" shape, wider on the outside and narrower on the inside. The purpose of these guide plates and the "V" shape is to guide the clamping plates as they move forward and touch the Torreya grandis tree. The guide plates then open, allowing the four wheels to clamp the tree, thus providing a space for fertilization.

[0015] Further improvements include a closed-off pointed end at the bottom of the shaft, with several discharge holes evenly distributed along the outer contour of the shaft's bottom. A pointed conical guide block, matching each discharge hole, is fixed to the bottom of the discharge channel. The closed-off pointed end of the shaft allows it to penetrate the mountain soil layer, providing guidance for subsequent shaft rotation and the spiral tunneling blades' excavation of the soil. The numerous discharge holes evenly distributed along the outer contour of the shaft's bottom, along with the pointed guide blocks, quickly guide fertilizer granules from the discharge channel into the mountain soil layer, preventing granules from failing to exit the shaft quickly.

[0016] Further improvements include a power source comprising a first drive motor, a lithium-ion rechargeable battery installed in the chassis, a control screen installed on the side of the material container, and a PLC controller installed on the vertical plate. The PLC controller is connected to the control screen, lithium-ion rechargeable battery, first drive motor, left turn button, right turn button, speed control knob, first drive motor, second drive motor, third drive motor, first hollow motor, second hollow motor, first electric cylinder, second electric cylinder, third electric cylinder, fourth electric cylinder, fifth electric cylinder, and vibrator wiring. The PLC controller here can control the coordinated operation of various components. The PLC controller in this solution is a commercially available programmable logic controller, and brands such as Mitsubishi, Schneider, Unicon, Delta, and Panasonic can be selected. In addition, the program setting of this PLC controller is consistent with the principle of the setting methods used in the market. Ordinary technicians can set program instructions themselves according to processing speed and efficiency requirements, which is convenient and quick. The function of the control panel here is to facilitate the setting of parameters and start-up and to facilitate operation. The function of the lithium-ion rechargeable battery here is to provide electrical energy, so that the fertilization device can be used more smoothly in mountainous environments where it is not convenient to connect to electricity, and it is not as bulky as fuel-powered components, making the operation of the fertilization device more flexible.

[0017] The beneficial effects of this invention are: 1) The fertilization device can be driven to move in mountainous environments through the chassis, tracked wheels and power source. Because the tracked wheels have a large working area, they are more suitable for mountainous environments, have higher stability, and are more stable to use without tipping over. 2) The fertilizer clamping mechanism for Torreya grandis trees can clamp Torreya grandis trees of different diameters, thereby automatically controlling the distance between the discharge hole and the Torreya grandis tree. As a result, the fertilizer is spread in a suitable position with the Torreya grandis tree, the fertilizer utilization rate is extremely high, and the production cost is greatly reduced. 3) The fertilizer granule conveying mechanism can efficiently deliver fertilizer granules to the Torreya grandis tree clamping and fertilization mechanism for application; 4) The fertilizer granule distributor can distribute fertilizer granules equally to each shaft and place them into the soil layer, thus avoiding the problem of different amounts of fertilizer granules coming out of the discharge holes at each shaft. This also avoids the problem of uneven nutrition caused by some areas having more fertilizer granules and others having fewer fertilizer granules in the four corners of the Torreya grandis tree.

[0030] The power source 3 includes a first drive motor 3-1, a lithium-ion rechargeable battery 14 installed in the chassis 1, a control screen 11 installed on the side of the material box 6-1, and a PLC controller 13 installed on the vertical plate 5-1. The PLC controller 13 is connected to the control screen 11, the lithium-ion rechargeable battery 14, the first drive motor 3-1, the left turn button 10-1, the right turn button 10-2, the speed adjustment knob 10-3, the first drive motor 3-1, the second drive motor 5-3, the third drive motor 6-8, the first hollow motor 5-10, the second hollow motor 12-2, the first electric cylinder 5-5, the second electric cylinder 8-1, the third electric cylinder 8-2, the fourth electric cylinder 9-1, the fifth electric cylinder 9-2, and the vibrator 6-10.

[0031] The working principle of this invention: When fertilizing the Torreya grandis trees 15 planted on an uphill slope, it is only necessary to first use the control panel 11 and the PLC controller 13 to transmit signals to control the first electric cylinder 5-5 and drive the vertical plate 5-1 to rotate clockwise, so that the two clamping plates 5-6 remain parallel to the horizontal plane (e.g., Figure 13As shown, this is to ensure that the two clamping plates 5-6 can vertically clamp the Torreya grandis tree 15. Then, the first drive motor 3-1 is started, which drives the clamping plates 5-6 to move through the track wheels 2 and is guided by the guide plate 5-6d, so that the two clamping plates 2 are squeezed apart by the Torreya grandis tree 15. At this time, the two first compression springs 5-7 are compressed and stored energy. The clamping plates 5-6 move forward until the four wheels 5-14 clamp the four corners of the Torreya grandis tree 15. At this time, the track wheels 2 stop running, the fertilizer applicator stops moving, and the rear stopper 8 stops the backward movement support. Immediately afterwards, the second drive motor 5-3 is controlled by the PLC controller 13 to run, which drives the mounting plate 5-2 to move down, and then synchronously drives the clamping plates 5-6 to move down. As plate 5-6 moves downwards, due to the slope of the mountainous terrain, each shaft 5-11 first presses against the mountain surface, causing it to compress and store energy via the movement of elliptical rod 5-8 and pressing the second compression spring 5-13. At this time, plate 5-9 and the first hollow motor 5-10 move upwards along with elliptical rod 5-8, causing each shaft 5-11 to touch the ground at varying elevations according to the terrain. Subsequently, the first hollow motors 5-10 are activated, driving the shafts 5-11 and the spiral tunneling blades 5-12 to rotate, simultaneously causing the mounting plate 5-2 to move downwards. Thus, each spiral tunneling blade 6-7 rotates and tunnels downwards, excavating a pit in the mountainous soil. Fertilizer granules in the holding bin 6-1 slide down to the first horizontal cylinder 6-3 through the gathering action of the feeding plate 6-2. Simultaneously, the rotating spiral propulsion blades 6-7 push the fertilizer granules to the first vertical cylinder 6-4. Then, the rotating spiral propulsion blades 6-7 in the first vertical cylinder 6-4 lift the fertilizer granules, and through the rapid guidance of the first downward-sloping plate 6-5, they reach the first downward-sloping cylinder 6-6. The rotating spiral propulsion blades 6-7 in the first downward-sloping cylinder 6-6 then evenly convey the fertilizer granules to the discharge pipe 6-6a. Finally, the second hollow motor 12-2 in the fertilizer granule distributor 12 rotates at equal angles... The fertilizer granules are rotated four times, thus distributing them equally to each discharge pipe 12-3. They then pass through the conveying hose 7, the hollow shaft of the first hollow motor 5-10, the discharge channel 5-11a, and the discharge hole 5-11b into the dug pits. Subsequently, the PLC controller 13 controls the second drive motor 5-3 to start and drive the mounting plate 5-2 to reset upwards. When fertilizing the next Torreya grandis tree 15, the above steps are repeated, resulting in very high efficiency. The fertilizer granules are located in the pits around the Torreya grandis tree 15, preventing loss even during heavy rain. Furthermore, the high utilization rate of the fertilizer ensures efficient fertilizer distribution.

[0032] When fertilizing the Torreya grandis trees 15 planted on a downhill slope, the fertilization method is similar to that on an uphill slope. The only difference is that the first electric cylinder 5-5 drives the vertical plate to rotate counterclockwise, thereby causing the two clamping plates 5-6 to be parallel to the horizontal plane, thus precisely clamping the Torreya grandis trees 15. Other operating steps are the same as the fertilization method for Torreya grandis trees 15 on an uphill slope. When fertilizing on a downhill slope, in order to make the fertilization device more stable, it is necessary to activate the front stop 9 to stop the forward movement and support (such as...). Figure 14 (As shown). This invention enables rapid and efficient fertilization in mountainous sloping environments, greatly reduces the labor intensity of workers, improves the fertilization efficiency of mountain Torreya grandis, increases fertilizer utilization, and significantly reduces the planting cost of Torreya grandis. It is worthy of widespread application.
