Description

Technical Field

[0001] The present invention relates to the field of transfer of agricultural and sideline products, and particularly to a transfer device for agricultural and sideline products. Background Art

[0002] Sugarcane is an important sugar crop in tropical and subtropical regions, and is widely planted in Southeast Asia, Cuba, southern China and other places. After harvesting, it needs to go through multiple processes such as defoliation, sorting, and packing before it can be stored or transported in the warehouse.

[0003] In the traditional sugarcane harvesting process, a walking tractor is usually used to cut the roots at the bottom. However, after harvesting, it is necessary to manually right the sugarcane and tie it into bundles, and then the sugarcane bundles are received by traditional transfer devices (such as simple trolleys or tractor trailers). However, the existing transfer devices lack a special fixing structure, and the sugarcane is prone to scatter or fall due to bumps during the transfer process, resulting in raw material losses. After the transfer vehicle arrives at the feeding port of the defoliator, it is still necessary to manually untie and push the sugarcane bundles, with low operating efficiency and a risk of mechanical injury. In the whole process, bundling and unloading both require manual operation, with high labor intensity and long operation cycle, and it is difficult to match the mechanized harvesting speed.

[0004] Based on the above situation, the present invention proposes a transfer device for agricultural and sideline products. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing transfer devices in the transfer process of sugarcane, such as the lack of a fixing structure, low unloading efficiency, strong dependence on manual labor, poor stability, and insufficient field adaptability, the technical problem to be solved is: to provide a transfer device for agricultural and sideline products.

[0006] The technical solution is: a transfer device for agricultural and sideline products, including a transfer vehicle, on which a support column is fixedly connected, and an inclined surface is provided at the top thereof. A hoisting motor is provided on the support column, and the output shaft of the hoisting motor is connected to a wire winding wheel through a coupling. A steel wire is wound around the wire winding wheel, and the movable end of the steel wire is connected to a clamping frame.

[0007] As a further preferred solution, a guiding groove is formed on the clamping frame, and the clamping frame slides on the support column through the guiding groove.

[0008] As a further preferred solution, a clamping motor is installed on the clamping frame, the output shaft of the clamping motor is connected to a bidirectional lead screw through a coupling, the bidirectional lead screw is rotatably connected to the clamping frame, and symmetrically distributed left grippers and right grippers are provided on the clamping frame. The left grippers and right grippers are threadedly connected to the bidirectional lead screw.

[0009] As a further preferred solution, flexible buffer sheets are installed on the inner sides of the left grippers and right grippers, and a torque sensor is provided in the clamping motor.

[0010] As a further preferred solution, symmetrically distributed ascending gears are rotatably connected to both sides of the clamping frame, and symmetrically distributed racks are provided inside the support columns. The ascending gears are meshed with the adjacent racks.

[0011] As a further preferred solution, a connecting rod is hinged to the support column and can rotate around the hinge point. A spur gear and a limit bump are provided at its end. A return torsion spring is connected between the connecting rod and the support column. The return torsion spring is wound around the connecting rod. A switching rack is fixedly connected to the clamping frame and meshed with the spur gear. A pushing motor is installed on the connecting rod. The output shaft of the pushing motor is connected to an I-shaped support frame through a coupling. The I-shaped support frame rotates on the connecting rod. Symmetrically distributed pushing plates are slidably connected to the I-shaped support frame. Symmetrically distributed return springs are connected between the symmetrically distributed pushing plates and the I-shaped support frame. The symmetrically distributed return springs are all wound around the I-shaped support frame.

[0012] As a further preferred solution, symmetrically distributed cams are fixedly connected to the support columns. Symmetrically distributed connecting blocks are rotatably connected to the symmetrically distributed cams. A supporting bottom plate is slidably connected between the symmetrically distributed connecting blocks. Connecting springs are connected between the supporting bottom plate and the symmetrically distributed connecting blocks. The symmetrically distributed connecting springs are all wound around the supporting bottom plate. Connecting pressure rods are fixedly connected to the left gripper and the right gripper.

[0013] As a further preferred solution, a fixing plate is fixedly connected to the transfer vehicle. Symmetrically distributed buffer sheets are slidably connected to the fixing plate. Symmetrically distributed buffer springs are connected between the buffer sheets and the fixing plate. The symmetrically distributed buffer springs are all wound around the buffer sheets.

[0014] Compared with the prior art, the present invention has the following advantages: By integrating functions such as efficient clamping, stable lifting, and automatic unloading, the present invention solves the problems existing in traditional sugarcane transfer devices, such as insecure fixation, low efficiency, strong dependence on manual labor, and poor stability, and realizes the efficient, safe, and mechanized transfer of sugarcane from harvesting to processing.

[0015] Through the synergistic effect of the bottom adaptive supporting device and the top clamping mechanism, the present invention realizes the dynamic stable transfer of sugarcane bundles under complex working conditions, significantly reduces the risks of slipping, loosening, and unloading jamming, and improves the operation efficiency and reliability.

[0016] The buffer sheets and buffer springs of the present invention cooperate with each other to effectively absorb the kinetic energy of the supporting bottom plate, reduce the impact force on the transfer vehicle, the flexible contact between the buffer sheets and the supporting bottom plate reduces the metal collision noise, improves the working environment, effectively protects the structure of the transfer vehicle, and improves the operation stability and service life of the equipment.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Example 1: Refer to the attached Figure 1-2 , a device for transporting agricultural and sideline products, including a transport vehicle 1 as the main body for transporting, which is responsible for carrying and moving sugarcane. A support column 11 is fixedly connected to the transport vehicle 1. The top of the support column 11 is provided with an inclined surface for providing structural support and a sliding track. A hoisting motor 12 is provided on the support column 11. The output shaft of the hoisting motor 12 is connected to a wire reel 13 through a coupling. A steel wire 14 is wound around the wire reel 13 to transmit the traction force. The movable end of the steel wire 14 is connected to a clamping frame 15 for fixing the sugarcane and lifting it along the support column 11. A guiding groove is formed on the clamping frame 15, and the clamping frame 15 slides on the support column 11 through the guiding groove.

[0030] During the sugarcane harvesting process, the staff first holds a bunch of sugarcane with their hands and controls the walking tractor to cut the root of this bunch of sugarcane. Then, this bunch of sugarcane is placed vertically on the right side of the clamping frame 15 and fixed by the clamping mechanism on the clamping frame 15. After the clamping is completed, then control the hoisting motor 12 to start, drive the wire reel 13 to wind up the steel wire 14, and pull the clamping frame 15 to move left and upward along the support column 11. The sugarcane is lifted from the vertical state to the horizontal state, and the axis of the stem is parallel to the advancing direction of the transport vehicle 1. Finally, control the transport vehicle 1 to move along the preset path until the root (cut end) of the sugarcane is aligned with the center of the feeding port of the leaf peeling machine.

[0031] Refer to the attached Figure 3 , the clamping mechanism includes a clamping motor 16 installed on the clamping frame 15. The output shaft of the clamping motor 16 is connected to a bidirectional lead screw 19 through a coupling. The bidirectional lead screw 19 is rotatably connected to the clamping frame 15. Symmetrically distributed left grippers 18 and right grippers 110 are provided on the clamping frame 15. The left grippers 18 and right grippers 110 are threadedly connected to the bidirectional lead screw 19 to achieve synchronous opposite movement. Flexible buffer sheets 4, such as rubber or silica gel, are installed on the inner sides of the left grippers 18 and right grippers 110 to reduce the local pressure. A torque sensor is provided in the clamping motor 16.

[0032] When the staff places a bunch of sugarcane on the right side of the clamping frame 15, the two grippers are in an open state (the distance between them is greater than the diameter of the sugarcane bundle), the clamping motor 16 is started, and the bidirectional screw 19 is driven to rotate clockwise, and the left gripper 18 and the right gripper 110 move inward synchronously, gradually narrowing the encirclement until they contact the sugarcane bundle and apply a preset clamping force, and automatically stop when the set torque is reached to avoid crushing the sugarcane. After clamping is completed, the bidirectional screw 19 achieves mechanical self-locking through the self-locking angle design (the thread lead angle is less than the friction angle), and can maintain the clamping state without continuous power supply. When the transfer vehicle 1 transports the sugarcane to the defoliator, the clamping motor 16 is controlled to drive the bidirectional screw 19 to rotate counterclockwise, and the left gripper 18 and the right gripper 110 move outward synchronously and return to the initial open position. The distance is expanded to the preset safety distance, and the sugarcane can be unloaded into the feed port of the defoliator.

[0033] After the clamping frame 15 clamps a certain amount of sugarcane through the clamping mechanism, the total weight increases significantly. Relying only on the steel wire 14 for traction may cause the following problems: the flexibility of the steel wire 14 is easily affected by inertia or wind, causing the clamping frame 15 to shake, resulting in the sugarcane breaking or falling out; the sliding friction resistance is large, and after long-term use, the guide groove of the clamping frame 15 and the contact surface of the support column 11 are easily worn, reducing the positioning accuracy. Therefore, the clamping frame 15 needs to be kept stable during its movement.

[0034] Reference Figure 2 Specifically, the two sides of the clamping frame 15 are rotatably connected to the symmetrically distributed rising gears 17, which are made of 45 steel. The inner side of the support column 11 is provided with symmetrically distributed racks, the modulus matches the gear, and the tooth surface hardness is HRC58-62. When the steel wire 14 provides vertical traction, the rising gear 17 meshes with the rack to provide lateral restraint force, forming a composite guide, and the double gears symmetrically mesh to offset the eccentric load torque, ensuring that the movement trajectory deviation of the clamping frame 15 is small. When the take-up wheel 13 reels the steel wire 14, the rising gear 17 rotates along the rack, converting the sliding friction into rolling friction, and reducing the resistance by more than 60%.

[0035] Reference Figures 4-6 When the device transfers the sugarcane to the feed port of the defoliator, the sugarcane in the clamping frame 15 needs to be unloaded into the feed port. The traditional manual operation requires manual pushing of the sugarcane, which is inefficient and easily causes the sugarcane to scatter. Therefore, it is necessary to design an automatic unloading mechanism to quickly and accurately push the sugarcane into the feed port after the transfer is in place, so as to achieve seamless connection of the process.

[0036] Specifically, a connecting rod 2 is hinged on the support column 11 and can rotate around the hinge point. The end of the connecting rod 2 is provided with a spur gear and a limit protrusion. A return torsion spring 26 is connected between the connecting rod 2 and the support column 11. The return torsion spring 26 is wound around the connecting rod 2 and is used to store and release energy to assist the connecting rod 2 to return to its original position. A switching rack 21 is fixedly connected to the clamping frame 15 and moves up and down with it. The switching rack 21 meshes with the spur gear of the connecting rod 2 to form a gear transmission system to drive the connecting rod 2 to rotate. The limit protrusion can limit the maximum rotation angle of the connecting rod 2 to 90°, ensuring accurate pushing stroke and avoiding excessive rotation. A pushing motor 22 is installed on the connecting rod 2. The output shaft of the pushing motor 22 is connected to an I-shaped support frame 23 through a coupling. The I-shaped support frame 23 rotates on the connecting rod 2. Symmetrically distributed pushing plates 24 are slidably connected to the I-shaped support frame 23. Symmetrically distributed return springs 25 are connected between the symmetrically distributed pushing plates 24 and the I-shaped support frame 23. The symmetrically distributed return springs 25 are all wound around the I-shaped support frame 23.

[0037] When the clamping frame 15 carrying the sugarcane is pulled up by the steel wire 14, the switching rack 21 on it will mesh with the spur gear of the connecting rod 2, pushing the spur gear to rotate, driving the connecting rod 2 to rotate counterclockwise around the hinge point, compressing the return torsion spring 26 to store energy. When the connecting rod 2 rotates to 90°, the limit protrusion abuts against the support column 11 and the movement stops. The pushing plate 24 is located above the tip of the sugarcane bunch.

[0038] When the sugarcane is transported to the feed inlet of the leaf stripping machine, ensure that the root of the sugarcane is aligned with the conveyor belt in the feed inlet of the leaf stripping machine. Control the clamping motor 16 to drive the bidirectional lead screw 19 to rotate counterclockwise, so that the left gripper 18 and the right gripper 110 move outward synchronously and slowly release the sugarcane bunch. At the same time, control the pushing motor 22 to drive the I-shaped support frame 23 to rotate, and the pushing plate 24 rotates accordingly. The rotating pushing plate 24 will contact the tip of the sugarcane and push the sugarcane obliquely placed on the top of the support column 11 to the conveyor belt at the feed inlet of the leaf stripping machine. The conveyor belt transports the sugarcane sliding downwards into the leaf stripping machine, ensuring that the root enters the processing position first. During the pushing process of the pushing plate 24, the return spring 25 will continuously deform and reset, absorbing the impact force between the sugarcane and the pushing plate 24, avoiding rigid collision resulting in sugarcane damage or mechanism jamming, and ensuring the pushing effect.

[0039] After the unloading is completed, the hoisting motor 12 rotates in reverse to release the steel wire 14. The clamping frame 15 descends and resets along the support column 11. The switching rack 21 descends accordingly, driving the connecting rod 2 to rotate clockwise. The return torsion spring 26 releases energy to assist in resetting. The limit protrusion can ensure that the connecting rod 2 accurately returns to the initial position. The pushing motor 22 stops running, completing the entire unloading process.

[0040] In this embodiment, by switching the meshing of the rack 21 with the spur gear of the connecting rod 2, the connecting rod 2 is driven to rotate counterclockwise by 90°. The limit bump is accurately positioned, enabling the pushing plate 24 to quickly move above the sugarcane tip, achieving efficient transportation. During unloading, the return spring 25 buffers the impact force of the pushing plate 24 through deformation, ensuring that the sugarcane root enters the leaf stripper first and avoiding damage. It can achieve seamless connection between sugarcane transportation and the feed inlet of the leaf stripper, ensuring that the sugarcane root is accurately aligned with the conveyor belt and improving the processing efficiency.

[0041] Embodiment 2: Refer to the appendix Figures 7-9 , during the operation of the sugarcane transporter 1, due to the unevenness of the planting land, the device jolts, and the sugarcane bundle is prone to internal slippage or overall sliding. In addition, when the sugarcane bundle changes from a vertical state to a horizontal state (tilt angle > 45°), the center of mass shifts, resulting in the superposition of the gravity component and the centrifugal force. The existing device only relies on the left gripper 18 and the right gripper 110 to clamp the periphery of the sugarcane bundle, and the bottom (cutting end) lacks restraint. The sugarcane is prone to downward slippage due to gravity. At the same time, the friction between the internal sugarcanes is low, and the single - root displacement during vibration triggers the chain - type slippage effect, ultimately leading to the loosening of the whole bundle structure.

[0042] Therefore, it is necessary to add an adaptively adjustable holding device at the cutting end of the sugarcane to provide bottom support and cooperate with the top clamping mechanism to form upper - and - lower two - way constraints, offsetting the inertial force of jolting and the gravity component during attitude transformation, ensuring the stable transportation of the sugarcane bundle throughout the process.

[0043] Specifically, symmetrically distributed cams 34 are fixedly connected to the support column 11. Connecting blocks 31 are rotatably connected to the symmetrically distributed cams 34. A support bottom plate 3 is slidably connected between the symmetrically distributed connecting blocks 31. Connecting springs 32 are connected between the support bottom plate 3 and the symmetrically distributed connecting blocks 31. The symmetrically distributed connecting springs 32 are all wound around the support bottom plate 3 to ensure that the holding device always clings to the bottom of the sugarcane. Connecting pressure rods 33 are fixedly connected to both the left gripper 18 and the right gripper 110. The top of the support bottom plate 3 contacts the cam 34. When moving with the clamping mechanism, the connecting block 31 is pressed through the connecting pressure rod 33 to control the flipping angle of the support bottom plate 3.

[0044] As described above, when a bundle of sugarcane is vertically placed on the right side of the clamping frame 15, the bottom cutting end is placed on the support bottom plate 3. Under the action of the gravity of the sugarcane itself, the connecting spring 32 will be stretched, keeping the support bottom plate 3 in a horizontal holding state. When the left gripper 18 and the right gripper 110 move inward through the bidirectional lead screw 19 to clamp the sugarcane bundle, the connecting pressure rod 33 also moves inward to directly above the connecting block 31.

[0045] When the steel wire 14 drives the traction clamping bracket 15 to move upward and leftward, the connecting pressure rod 33 presses the connecting block 31, causing the supporting bottom plate 3 to rotate counterclockwise, synchronizing with the inclined track of the sugarcane. Moreover, the protrusion of the cam 34 abuts against the supporting bottom plate 3, compressing the connecting spring 32 to generate a reverse elastic force, ensuring that the supporting bottom plate 3 closely adheres to the bottom of the sugarcane to offset the component of gravity and the inertial force.

[0046] When the clamping motor 16 drives the left gripper 18 and the right gripper 110 to move outward, the connecting pressure rod 33 disengages from the connecting block 31. Under the action of gravity, the supporting bottom plate 3 rotates clockwise to reset. The cutting end of the sugarcane is aligned with the conveyor belt of the leaf stripping machine. The overweight sugarcane slides onto the conveyor belt due to gravity and cooperates with the pushing plate 24 to complete the unloading.

[0047] Through the synergistic effect of the bottom adaptive supporting device and the top clamping mechanism in this embodiment, the dynamic and stable transfer of the sugarcane bundle under complex working conditions is realized, significantly reducing the risks of slippage, loosening and unloading jamming, and improving the operation efficiency and reliability.

[0048] As described above, during the automatic reset process of the supporting bottom plate 3, due to its own gravity and inertia, it will strike the transport vehicle 1, generating a large noise and possibly causing structural damage. Therefore, a buffer device needs to be added during the reset process of the supporting bottom plate 3 to reduce the impact force and protect the equipment.

[0049] Refer to the appendix Figure 10 Specifically, a fixed plate 41 is fixedly connected to the transport vehicle 1. Symmetrically distributed buffer pieces 4 are slidably connected to the fixed plate 41 for contacting the supporting bottom plate 3 and absorbing the impact force. Symmetrically distributed buffer springs 42 are connected between the buffer pieces 4 and the fixed plate 41. The symmetrically distributed buffer springs 42 are all wound around the buffer pieces 4, absorbing the kinetic energy of the supporting bottom plate 3 through compression deformation to provide a buffering effect.

[0050] When the supporting bottom plate 3 rotates clockwise to reset under the action of gravity, it will strike the buffer piece 4, causing the buffer piece 4 to slide leftward and compressing the buffer spring 42 to absorb the impact kinetic energy. The buffer spring 42 converts the kinetic energy of the supporting bottom plate 3 into elastic potential energy through compression deformation, reducing the impact force transmitted to the transport vehicle 1. After the supporting bottom plate 3 stops moving, the buffer spring 42 returns to its original state, and the buffer piece 4 slides rightward to reset, preparing for the next buffering.

[0051] In this embodiment, through the mutual cooperation of the buffer piece 4 and the buffer spring 42, the kinetic energy of the supporting bottom plate 3 is effectively absorbed, the impact on the transport vehicle 1 is reduced, the flexible contact between the buffer piece 4 and the supporting bottom plate 3 reduces the metal collision noise, improves the working environment, effectively protects the structure of the transport vehicle 1, and improves the operation stability and service life of the equipment.

[0052] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
