Description

Technical Field

[0001] This invention relates to the field of deep cultivation equipment technology, specifically a deep cultivation device for Poria cocos. Background Technology

[0002] As an important traditional Chinese medicine, Poria cocos is typically cultivated on well-drained, loose-soiled hillsides. Deep plowing is essential before sowing to cultivate Poria cocos. Deep plowing effectively breaks up the plow pan, bringing deep soil to the surface and burying surface weeds and crop residues, thus loosening, mixing, and breaking up the soil. This significantly improves soil structure, increases porosity, and enhances water and fertilizer retention capacity, creating a loose and well-aerated ideal soil environment for the colonization of Poria cocos mycelium and the growth of sclerotia. This is a crucial agronomical measure for achieving high yields and quality of Poria cocos.

[0003] Hillside areas are typically sheltered from the wind and sunny, allowing them to fully utilize sunlight to raise ground temperature and create a diurnal temperature range. This temperature difference stimulates mycelium to decompose pine cellulose, accelerating the formation of Poria cocos sclerotia, while also helping to suppress termites and other pests. Furthermore, due to weathering, the topsoil on hillsides is often sandy, which meets the growth requirements of Poria cocos.

[0004] Currently, during the cultivation of Poria cocos on hillsides, when tilling the land with rotary tillers, the soil layer on hillsides often contains stones of varying sizes. This means that existing deep tillage machinery often lacks an effective autonomous sensing and avoidance mechanism when encountering stones during tillage operations. As a result, the tillage components of the rotary tiller collide hard with the stones, which can easily lead to deformation, breakage, or even equipment failure. Furthermore, existing equipment lacks an effective emergency handling mechanism after a collision, and usually can only be completely stopped for manual repair, which further disrupts the continuity and overall efficiency of deep tillage operations. Summary of the Invention

[0005] The purpose of this invention is to provide a deep cultivation device for Poria cocos to solve the problems mentioned in the above process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A deep cultivation device for Poria cocos includes a traction frame and a mounting frame rotatably connected to the rear side of the traction frame. A ground-penetrating radar for monitoring stones is fixedly installed on the front side of the traction frame. Limiting components are provided between the traction frame and the mounting frame on both sides. Multiple deep cultivation components are provided on the mounting frame.

Hydraulic push rods are rotatably connected between the traction frame and the multiple movable seats; A U-shaped bracket for unlocking the limiting component is slidably connected to the mounting bracket on the rear side of the movable seat.

[0007] As a preferred embodiment of the Poria cocos deep cultivation device of the present invention, the mounting frame has multiple through holes on the side near the traction frame, and the ends of the multiple hydraulic push rods pass through the through holes and are rotatably connected to the traction frame.

[0008] As a preferred embodiment of the Poria cocos deep cultivation device of the present invention, the top of the movable seat is rotatably connected to a main shaft, and a universal coupling is connected between the deep cultivation auger and the main shaft.

[0009] As a preferred embodiment of the Poria cocos deep cultivation device of the present invention, the universal coupling includes a fork-shaped connector fixed coaxially with the main shaft and the deep cultivation auger respectively, and a cross shaft rotatably connected between the two fork-shaped connectors.

[0010] As a preferred embodiment of the Poria cocos deep cultivation device of the present invention, the top of the mounting frame is provided with multiple through slots, the top of the mounting frame is rotatably connected with multiple rotating shafts, the tops of the multiple main shafts pass through the through slots and are coaxially fixed with worm gears, and worms are slidably connected to the multiple rotating shafts, and the multiple worms and multiple worm gears are meshed and connected in a one-to-one correspondence.

[0011] As a preferred embodiment of the Poria cocos deep cultivation device of the present invention, the rotating shaft is provided with a groove, and a protrusion is fixedly installed on the inner side of the worm gear, the protrusion slidingly fitting in the groove.

[0012] As a preferred embodiment of the Poria cocos deep cultivation device of the present invention, wherein: a plurality of the rotating shafts are coaxially fixed with sprockets at their ends, and a chain is sleeved on the outside of the plurality of sprockets.

[0013] As a preferred embodiment of the Poria cocos deep cultivation device of the present invention, the limiting component includes a slide rod that slides into the mounting frame at one end and a clamp fixed to the end of the slide rod. A first spring is fixedly connected between the end of the slide rod that extends into the mounting frame and the mounting frame. A trapezoidal block is fixedly installed at one end of the clamp. The traction frame is provided with a groove that slides with the other end of the clamp. As a preferred embodiment of the Poria cocos deep cultivation device of the present invention, a pressure sensor is fixedly installed inside the slot on the side near the mounting frame.

[0014] As a preferred embodiment of the Poria cocos deep cultivation device of the present invention, a plurality of second springs are fixedly connected between the side of the U-shaped frame away from the moving seat and the mounting frame, and both ends of the U-shaped frame are provided with inclined surfaces that slide in cooperation with two trapezoidal blocks respectively.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In the process of land preparation for planting Poria cocos on hillsides, this invention can detect the location and size of hard rocks in the soil in real time using ground-penetrating radar. Based on the detection results, the hydraulic push rod is controlled to extend and retract, causing the deep tillage component to move backward. At the same time, through the meshing of gears and racks, the rotating plate drives the rotating frame to move along the arc-shaped guide groove. This causes the deep tillage auger to gradually lift backward while moving backward, so as to actively avoid hard rocks in the soil that may affect the operation of the deep tillage auger. This prevents the hard rocks from continuously colliding with the deep tillage auger, which could cause deformation or damage, and ensures the continuity and overall efficiency of the deep tillage operation.

[0016] 2. As mentioned above, the multiple deep tillage components can be controlled by corresponding hydraulic push rods to move the corresponding deep tillage augers backward while gradually lifting them backward. The deep tillage augers can be adjusted individually without affecting the other deep tillage augers from continuing to perform deep tillage operations on the soil, ensuring deep tillage effect and work efficiency.

[0017] 3. Due to the transmission angle limitation of the universal coupling between the deep tillage auger and the main shaft, when the moving seat moves to the end of its stroke away from the traction frame, the universal coupling has bent to its maximum transmission angle. If the deep tillage auger still cannot avoid the hard rock at this time, the hydraulic push rod can be pushed out further. As the moving seat moves to the end of its stroke, it will push the U-shaped frame to move, causing the limit component to unlock. At this time, the continued push of the hydraulic push rod can cause the entire mounting frame to tilt backward, thereby driving all the deep tillage augers to continue to lift backward until the deep tillage augers can completely avoid the hard rock. This further expands the avoidance range of the deep tillage augers and ensures the stable rotation of the deep tillage augers during the avoidance process, thereby ensuring the continuity and overall efficiency of the deep tillage operation.

[0018] 4. If, during the use of ground-penetrating radar, changes in soil moisture or salinity cause electromagnetic wave absorption and attenuation, reducing the detection depth, then when the deep-plowing auger collides with a hard rock, the auger will exert a backward force on the mounting frame via the moving seat. This force is then applied to the pressure sensor in the slot on the traction frame through the end of the clamp. When the pressure sensor detects an abnormally high pressure, the main controller reacts quickly, causing multiple hydraulic push rods to extend synchronously and simultaneously increasing the power of the ground-penetrating radar. Through this process, the deep-plowing auger gradually lifts backward while moving backward. This backward movement allows the auger to exit from the outside of the hard rock, avoiding secondary collisions with the rock during the backward lifting process. Then, based on the detection results of the ground-penetrating radar after the power increase, the deep-plowing auger is adjusted to ensure the continuous deep-plowing operation and maintain its continuity and overall efficiency.

[0019] 5. During subsequent deep tillage operations after the ground penetrating radar power is increased, the hydraulic push rod retracts, causing the moving seat to move. When the moving seat moves to the end of its stroke near the traction frame, it drives the mounting frame to rotate, which in turn drives the card holder to re-engage in the slot via the slide rod. During subsequent deep tillage operations, the pressure sensor can continue to monitor. If the pressure is detected to rise abnormally again, it indicates that the fault may still exist or a new collision may have occurred. At this time, the machine must be stopped immediately, and the ground penetrating radar or related transmission components must be inspected to avoid more serious equipment damage caused by operating with the fault.

[0033] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention. The invention is by no means limited to any specific configurations and algorithms presented below, but covers any modifications, substitutions, and improvements to elements, components, and algorithms without departing from the spirit of the invention. Well-known structures and techniques are not shown in the drawings and the following description in order to avoid unnecessarily obscuring the invention.

[0034] Example 1, referring to Figure 1-12 The first embodiment of the present invention provides a Poria cocos deep cultivation device, which includes a traction frame 1 and a mounting frame 2 rotatably connected to the rear side of the traction frame 1. A ground-penetrating radar 3 for monitoring stones is fixedly installed on the front side of the traction frame 1. Limiting components are provided between the traction frame 1 and the mounting frame 2 on both sides. Multiple deep cultivation components are provided on the mounting frame 2. The deep tillage component includes a movable seat 24 slidably connected to the mounting frame 2 and two arc-shaped guide grooves 243 opened on both sides of the movable seat 24. A rotating frame 245 is slidably connected between the two arc-shaped guide grooves 243, and a deep tillage auger 21 is rotatably connected inside the rotating frame 245. A rotating plate 244 is rotatably connected to one side of the movable seat 24. One end of the rotating plate 244 is fixedly connected to the rotating frame 245. A gear 242 is coaxially fixed at the rotatable connection between the rotating plate 244 and the movable seat 24. A rack 241 that meshes with the gear 242 is fixedly installed on the mounting frame 2. Hydraulic push rods 25 are rotatably connected between the traction frame 1 and multiple movable seats 24 respectively; A U-shaped bracket 23 for unlocking the limiting component is slidably connected to the mounting bracket 2 on the rear side of the movable base 24.

[0035] The mounting bracket 2 has multiple through holes on the side near the traction frame 1, and the ends of multiple hydraulic push rods 25 pass through the through holes and are rotatably connected to the traction frame 1.

[0036] The top of the movable seat 24 is rotatably connected to the main shaft 22, and the deep tillage auger 21 is connected to the main shaft 22 by a universal coupling 246.

[0037] During use, the traction frame 1 is first installed behind the traction machine, which can preferably be an agricultural tractor. Then, multiple deep tillage screws 21 are driven to rotate, and the hydraulic device connected to the tail of the traction machine causes the traction frame 1 to move down as a whole, thereby driving the mounting frame 2 to move down. This allows the continuously rotating deep tillage screws 21 in the multiple deep tillage components inside the mounting frame 2 to be inserted into the soil. The deep tillage screws 21 are used to turn the soil, loosen the soil, mix the soil, and break up the soil, thereby achieving the land preparation treatment for the hillside environment where Poria cocos is planted.

[0038] Then, as the traction machinery moves the equipment in the field, the ground-penetrating radar 3 detects the soil in front of the deep tillage auger 21 along the path. The ground-penetrating radar 3 emits and receives electromagnetic waves to detect the location and size of hard stones in the soil in real time. The ground-penetrating radar 3 then transmits the detected data to the main controller. The main controller determines the impact of the hard stones on the deep tillage auger 21 based on their location and size. If the hard stones are determined to obstruct the deep tillage auger 21, the main controller pre-controls the hydraulic push rod 25 on the corresponding deep tillage component side to extend its telescopic end, causing the moving seat 24 to move rearward within the mounting frame 2. During this rearward movement, the moving seat 24 drives the gear 24 on the outer side of the rotating plate 244. 2. Movement: Gear 242 meshes with rack 241 on mounting frame 2, causing gear 242 to roll on rack 241. Gear 242 drives rotating plate 244 to rotate, causing the other end of rotating plate 244 to drive rotating frame 245 to move along arc-shaped guide groove 243. Rotating frame 245 drives the internally rotatably connected deep tillage auger 21 to lift to the rear. This allows the deep tillage auger 21 to gradually lift to the rear while moving to the rear, raising the bottom of the deep tillage auger 21. This enables the active and inevitable avoidance of hard stones in the soil, preventing continuous collisions between hard stones and deep tillage auger 21 during deep tillage operations, thus ensuring the continuity and overall efficiency of deep tillage operations.

[0039] Furthermore, each of the multiple deep tillage components has a hydraulic push rod 25 on one side of its movable base 24. The main controller can send control signals according to the specific location of the hard rock to control the extension and retraction of different hydraulic push rods 25. This controls the corresponding deep tillage auger 21 to move backward while gradually lifting backward, allowing the deep tillage auger 21 to be adjusted individually. During its adjustment, it will not affect the other deep tillage auger 21 from continuing to perform deep tillage operations on the soil, ensuring the deep tillage effect and work efficiency.

[0040] The rotation of the main shaft 22 drives the rotation of the deep tillage auger 21 through the universal coupling 246. Due to the limited transmission angle of the universal coupling 246 between the deep tillage auger 21 and the main shaft 22, the universal coupling 246 has a maximum deflection angle to ensure stable rotation of the deep tillage auger 21. When the hydraulic push rod 25 pushes the movable seat 24 along the mounting frame 2 to the end of its stroke in the direction away from the traction frame 1, the universal coupling 246 has already bent to its maximum transmission angle. If the lifting height of the deep tillage auger 21 is still insufficient to avoid the hard rock, the hydraulic push rod 25 can continue to extend. Simultaneously, as the hydraulic push rod 25 pushes the movable seat 24 to the end of its stroke in the direction away from the traction frame 1, the movable seat 24 pushes the U-shaped frame 23 to move, thereby unlocking the limit component. At this time, the traction... The guide frame 1 and the mounting frame 2 can rotate relative to each other. The continued extension of the hydraulic push rod 25 can cause the moving seat 24 to push the mounting frame 2 to move, causing the mounting frame 2 to rotate backward relative to the traction frame 1, causing the mounting frame 1 to tilt backward as a whole. This drives all the deep tillage augers 21 to continue to lift backward until the deep tillage augers 21 can completely avoid hard rocks. During this process, the main controller judges the extension stroke of the corresponding hydraulic push rod 25. When the mounting frame 2 is rotating, the main controller controls the other hydraulic push rods 25 to extend the corresponding length, thereby avoiding the other hydraulic push rods 25 from affecting the rotation of the mounting frame 2. This further expands the avoidance range of the deep tillage augers 21, and ensures the stable rotation of the deep tillage augers 21 during the avoidance process, thus ensuring the continuity and overall efficiency of the deep tillage operation.

[0041] Then, based on the detection results of the ground penetrating radar 3, after the deep tillage auger 21 moves to avoid the hard rocks, the main controller controls the hydraulic push rod 25 to retract. When the mounting frame 2 is rotating, the retraction of the hydraulic push rod 25 drives the corresponding moving seat 24 to move towards the traction frame 1. The moving seat 24 drives the gear 242 on the outside of the rotating plate 244 to move. The gear 242 meshes with the rack 241 on the mounting frame 2, causing the gear 242 to roll on the rack 241. The gear 242 drives the rotating plate 244 to rotate in the opposite direction, causing the other end of the rotating plate 244 to drive the rotating frame 245 to move in the opposite direction along the arc-shaped guide groove 243. This causes the rotating frame 245 to drive the internally rotating deep tillage auger 21 to rotate downward, thereby gradually restoring the deep tillage auger 21 to a vertical state, thus continuing the deep tillage operation.

[0042] In addition, when one of the deep tillage augers 21 rotates to avoid a rock, it drives the mounting frame 2 to move. After avoiding the hard rock, the main controller simultaneously controls multiple hydraulic push rods 25 to retract. The moving seats 24 of the remaining deep tillage components are all located at the ends close to the traction frame 1. This causes the moving seats 24 to drive the mounting frame 2 to rotate toward the traction frame 1 when the remaining hydraulic push rods 25 retract, until one side of the mounting frame 2 contacts one side of the traction frame 1. Then, the hydraulic push rods 25 corresponding to the deep tillage auger 21 that is still in a deflected state continue to retract. Through the above process, the deep tillage auger 21 is gradually restored to a vertical state, making it easier to continue deep tillage operations.

[0043] The main controller mentioned in this article can be any conventional, known device that performs control, such as a computer, and will not be elaborated upon here.

[0044] Example 2, refer to Figure 1-12 This is the second embodiment of the present invention, which differs from the first embodiment in that: Universal coupling 246 includes a fork-shaped connector fixed coaxially with the main shaft 22 and the deep tillage auger 21 respectively, and a cross shaft rotatably connected between the two fork-shaped connectors.

[0045] The top of the mounting bracket 2 is provided with multiple through slots, and multiple rotating shafts 223 are rotatably connected to the top of the mounting bracket 2. The tops of multiple main shafts 22 pass through the through slots and are coaxially fixed with worm gears 222. Worms 221 are slidably connected to each of the multiple rotating shafts 223, and the multiple worm gears 221 and multiple worm gears 222 are meshed and connected in a one-to-one manner.

[0046] A groove 226 is provided on the rotating shaft 223, and a protrusion 227 is fixedly installed on the inner side of the worm gear 221. The protrusion 227 is slidably fitted in the groove 226.

[0047] Multiple shafts 223 are coaxially fixed with sprockets 224 at their ends, and chains 225 are sleeved on the outside of the multiple sprockets 224.

[0048] The deep-plowing auger 21 includes a rod body and helical blades fixed to the outside of the rod body, with a tapered drill bit fixed to the bottom of the rod body. Each of the deep tillage augers 21 is fitted with a flexible baffle on its outer side, which is fixedly connected to the bottom of the mounting frame 2 to block soil.

[0049] During operation, driving one of the rotating shafts 223 to rotate causes the sprocket 224 to rotate, which in turn causes the chain 225 sleeved on the outside of the multiple sprockets 224 to rotate. This chain 225 then drives the remaining sprockets 224 to rotate, thereby causing the multiple rotating shafts 223 to rotate synchronously. Each of the multiple rotating shafts 223 drives the corresponding worm 221 to rotate through its groove 226 and the protrusion 227 on the inner side of the worm 221. When the multiple worms 221 rotate, they drive the meshing worm wheels 222 to rotate, and the multiple worm wheels 222 drive the corresponding main shaft 22 to rotate. The main shaft 22 drives one of the fork joints of the universal coupling 246 to rotate, and then drives the other fork joint to rotate through the cross shaft, so that the other fork joint drives the deep tillage auger 21 to rotate. In this way, the main shaft 22 transmits torque through the universal coupling 246. When the axis of the deep tillage auger 21 is deflected by a certain angle from that of the main shaft 22 through the universal coupling 246, the deep tillage auger 21 can still rotate stably, ensuring the continuous soil turning operation during the active avoidance process of the deep tillage auger 21. This ensures that the deep tillage auger 21 can be smoothly pulled forward by the traction equipment, avoiding large resistance from unturned soil.

[0050] The conical structure of the drill bit at the bottom of the deep tillage auger 21 ensures that the auger 21 is stably inserted into the soil. Then, the spiral blades on the outside of the auger continuously turn the soil up, achieving the functions of turning, loosening, mixing and breaking up the soil. In addition, flexible baffles that are fixedly connected to the bottom of the mounting frame 2 are fitted on the outside of each of the deep tillage auger 21 to prevent the turned-up soil from entering the mounting frame 2 and causing blockage of the transmission structure inside the mounting frame 2. This ensures the stable operation of the equipment and guarantees the continuity and overall efficiency of the deep tillage operation.

[0051] The remaining structure is the same as that in Example 1.

[0052] Example 3, referring to Figure 3-11 This is the third embodiment of the present invention, which differs from the second embodiment in that: The limiting component includes a slide rod 233 that slides into the mounting frame 2 at one end and a clip 231 fixed to the end of the slide rod 233. A first spring 234 is fixedly connected between the end of the slide rod 233 that extends into the mounting frame 2 and the mounting frame 2. A trapezoidal block 2311 is fixedly installed at one end of the clip 231. The traction frame 1 is provided with a slot 232 that slides with the other end of the clip 231.

[0053] A pressure sensor is fixedly installed inside the slot 232 on one side near the mounting bracket 2.

[0054] Multiple second springs 235 are fixedly connected between the side of the U-shaped frame 23 away from the movable seat 24 and the mounting frame 2. Both ends of the U-shaped frame 23 are provided with inclined surfaces that slide in cooperation with two trapezoidal blocks 2311 respectively.

[0055] During use, when the movable seat 24 moves to the end of its stroke in the direction away from the traction frame 1, the movable seat 24 pushes the U-shaped frame 23 to move. At the same time, the U-shaped frame 23 compresses the second spring 235. Through the interaction between its inclined surface and the inclined surface on the trapezoidal block 2311, the trapezoidal block 2311 drives the card holder 231 to move outward. At the same time, the slide rod 233 slides in the mounting frame 2 and stretches the first spring 234, so that the end of the card holder 231 is pulled out from the card slot 232 on the traction frame 1, thereby releasing the traction frame 1 from the locking state of the mounting frame 2.

[0056] During the process of the deep tillage auger 21 returning to vertical, the mounting frame 2 rotates in the opposite direction until it contacts one side of the traction frame 1. The mounting frame 2 then moves the end of the card holder 231 to one side of the card slot 232 on the traction frame 1 via the slide rod 233. As the moving seat 24 continues to move, when the moving seat 24 separates from the U-shaped slide 23, the second spring 235 pushes the U-shaped frame 23 to reset. At the same time, the restoring force of the first spring 234 drives the slide rod 233 to move toward the inside of the mounting frame 2, so that the end of the card holder 231 is reinserted into the card slot 232, completing the locking reset.

[0057] During the use of the ground-penetrating radar 3, changes in soil moisture or salinity cause the electromagnetic waves emitted by the radar 3 to be absorbed and attenuated, reducing its detection depth. Therefore, when the deep-plowing auger 21 moves, the reduced sensitivity of the radar 3 causes it to collide with hard rocks. This collision causes the auger 21 to generate a backward force on the mounting frame 2 via the rotating frame 245 and the moving seat 24. This force is then transmitted through the sliding rod 233 to the clamp 231, and finally applied to the pressure sensor in the slot 232 of the traction frame 1. When the pressure sensor detects an abnormally high pressure... Upon receiving the signal, the main controller reacts swiftly, causing multiple hydraulic push rods 25 to extend synchronously and simultaneously increasing the power of the ground-penetrating radar 3. The deep-plowing auger 21, through the aforementioned mechanical transmission process, moves backward while gradually lifting backward. This backward movement first allows the deep-plowing auger 21 to exit from the outside of the hard rock, thus avoiding secondary collisions with the hard rock during subsequent rearward lifting. As the power of the ground-penetrating radar 3 increases, the detection depth also increases. Then, based on the detection results of the ground-penetrating radar 3 after the power increase, the hydraulic push rods 25 are further controlled to extend and retract, thereby adjusting the deep-plowing auger 21. This ensures that the deep-plowing operation can continue after obstacle avoidance, guaranteeing the continuity and overall efficiency of the deep-plowing operation.

[0058] In subsequent deep tillage operations after the power of the ground penetrating radar 3 is increased, the hydraulic push rod 25 retracts, causing the movable seat 24 to move. When the movable seat 24 moves to the end of its stroke near the traction frame 1, it drives the mounting frame 2 to rotate, thereby causing the end of the clamp 231 to move to the side of the clamp slot 232. Then, through the elastic force of the first spring 234, the slide rod 233 drives the clamp 231 to re-clamp into the clamp slot 232. In subsequent deep tillage operations, the pressure sensor resumes its real-time monitoring function. If the pressure is detected to rise abnormally again, it indicates that the fault may still exist or a new collision may have occurred. At this time, the machine must be stopped immediately, and the ground penetrating radar 3 or related transmission components must be inspected to avoid more serious equipment damage caused by operating with a fault.

[0059] The remaining structure is the same as that in Example 2.
