Description

Technical Field

[0001] The invention relates to the technical field of durian picking, and in particular to a durian picking tool. Background Art

[0002] The height of a durian tree is affected by factors such as the growing environment, variety, and age. Generally speaking, wild durian trees can grow to 20 to 30 meters high. Artificially cultivated durian trees are usually kept within a height range of 10 to 20 meters due to daily pruning and management. Therefore, durian picking is a challenging task. Because durian trees are relatively high, they are usually picked by manual climbing or with the help of long poles, or by using telescopic poles with scissors, machetes, etc. driven by the front end. When picking, a cushion such as canvas will be laid under the tree, and the durian will fall onto the cushion to complete the picking process.

[0003] When the durian falls, the pickers below will be in great danger, and the durian is only buffered once, and the kinetic energy of its fall is completely consumed in one buffer, which can easily damage the durian or damage its flesh under the action of inertia. Therefore, we propose a durian picking tool. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a durian picking tool, comprising:

[0005] A bottom plate, the bottom of which is fixedly connected with a supporting leg, wherein a plurality of the supporting legs are provided and the plurality of the supporting legs are evenly distributed along the circumference of the bottom plate;

[0006] A buffer mechanism, the buffer mechanism is arranged on a side of the bottom plate away from the supporting legs, and the buffer mechanism is fixedly connected to the bottom plate;

[0007] A picking mechanism, wherein the picking mechanism is arranged directly above the buffer mechanism and is fixedly connected to the surface of the bottom plate;

[0008] Wherein, the buffer mechanism comprises:

[0009] An upper curtain, which has a hole in the center and is made of canvas, and is used to receive the cut durian;

[0010] A lower curtain, which has a hole in the center and is made of canvas, and is used to receive the durian that falls from the upper curtain again;

[0011] A tightening assembly having a tensioning structure for controlling the retraction and extension of the center holes of the upper curtain and the lower curtain, the two side surfaces of the tightening assembly being fixedly connected to the inner side surfaces of the upper curtain and the lower curtain respectively, and the tightening assembly being fixedly connected to the top of the bottom plate;

[0012] A material discharge assembly having a buffer structure for buffering durian for the third time, wherein the material discharge assembly is arranged on a side of the lower curtain close to the bottom plate, and the material discharge assembly is fixedly connected to the top of the bottom plate;

[0013] When the durian is cut, it first falls on the top of the upper curtain. The middle of the upper curtain is impacted, causing the center hole of the upper curtain to expand. While expanding, it drives one end of the tightening component to relax, and the center hole of the lower curtain shrinks. Then the durian falls to the top of the lower curtain. The lower curtain is impacted, and the center hole of the lower curtain expands. On the contrary, the tightening component controls the center hole of the upper curtain to shrink. Finally, the durian passes through the lower curtain and enters the inside of the unloading component. The unloading component unloads the durian. Finally, the durian falls to the bottom of the bottom plate. The buffer structures of the upper curtain, lower curtain, and unloading component buffer the durian three times in turn, fully consuming its gravitational potential. The kinetic energy that can be converted can prevent the durian from falling directly to the ground and causing damage, and the segmented buffering can effectively reduce the reaction force on the durian, further preventing the durian from being damaged. A tightening component is set to link the changes of the center holes of the upper curtain and the lower curtain. When the center hole of the upper curtain expands, the center hole of the lower curtain contracts, thereby ensuring that the durian can stably contact the lower curtain, thereby ensuring the stability of the second buffering. The center hole of the lower curtain expands and the center hole of the upper curtain contracts, making it difficult for the durian to fly out from the gap between the upper and lower curtains, which can effectively prevent the durian from flying out and being damaged, and at the same time avoid injuring the operators nearby.

[0014] Furthermore, the supporting leg is provided with a hole at a position away from the bottom plate, and an elliptical plate is fixedly connected to the inner wall of the hole of the supporting leg, and the elliptical plate is made of elastic material. The elliptical plate is arranged so that when the supporting leg is subjected to pressure, the elliptical plate is deformed, thereby achieving a buffering effect, and the hollow structure of the elliptical plate can conveniently provide fixation or counterweight for the supporting leg, which can effectively prevent the supporting leg from rebounding under the reaction force of the falling durian, and prevent the supporting position of the bottom plate from being offset.

[0015] Furthermore, the center hole of the upper curtain is initially in a relaxed state, and the center hole of the lower curtain is initially in a semi-expanded state, and the center hole of the upper curtain is larger than the center hole of the lower curtain. When the center hole of the upper curtain begins to relax, it can ensure the expansion when the durian falls, and the contraction after the durian passes through. When the center hole of the lower curtain begins to contract, it can fully receive the durian when it falls, preventing the small durian from passing directly, and the degree of deformation after the durian passes through is greater. The kinetic energy of the durian has to overcome the elastic force of the expansion of the lower curtain, which can more effectively consume its kinetic energy and obtain a better buffering effect.

[0016] Further, the tightening assembly includes a first pull rod, which is arranged inside the upper curtain, and the surface of the first pull rod is fixedly connected to the inner side surface of the upper curtain, and there are several first pull rods evenly distributed along the circumference of the upper curtain, and a second pull rod is arranged inside the lower curtain, and the surface of the second pull rod is fixedly connected to the inner side surface of the lower curtain, and there are several second pull rods evenly distributed along the circumference of the lower curtain, by pulling the first pull rod, several circumferentially arranged first pull rods can achieve uniform expansion of the upper curtain, and by pulling the second pull rod, several circumferentially arranged second pull rods can achieve uniform expansion of the lower curtain.

[0017] Furthermore, the end of the first pull rod away from the center of the upper curtain is fixedly connected to the first connecting frame, the surface of the first connecting frame is fixedly connected to the outermost inner side surface of the upper curtain, and the end of the second pull rod away from the center of the lower curtain is fixedly connected to the second connecting frame, the surface of the second connecting frame is fixedly connected to the outermost inner side surface of the lower curtain, and the first connecting frame and the second connecting frame are both arranged in a bow shape, the first pull rod moves to drive the first connecting frame to move, and the second pull rod moves to drive the second connecting frame to move.

[0018] The cam is connected to the second connecting frame by a lever, and the lever is connected to the second connecting frame by a lever, and the lever is moved to move the lever, so that the lever can be retracted and retracted, thereby preventing the lever from sliding out of the way and causing the lever to retract.

[0019] Furthermore, the feeding assembly includes a feeding cone, which is arranged at the gap between the lower curtain and the bottom plate, and a connecting leg is fixedly connected to the side of the feeding cone close to the bottom plate, and a side of the connecting leg away from the feeding cone is fixedly connected to a side of the bottom plate away from the supporting leg. The durian passes through the lower curtain and then enters the feeding cone, and finally passes through the feeding cone and the bottom plate in sequence to complete the entire picking process.

[0020] Furthermore, a baffle is provided inside the discharge cone, and the baffle is fixedly connected to the inner side surface of the discharge cone. The baffle is made of elastic material, and the baffle is naturally inclined inside the discharge cone. Before the durian contacts the discharge cone, it first hits the baffle, and the elastic baffle is deformed, thereby further buffering and preventing the durian from being bumped.

[0021] Furthermore, the baffles are arranged in several groups on the inner circumference of the unloading cone, each group of baffles is provided with several baffles, and the several baffles are evenly distributed along the slope of the unloading cone, and the several baffles have the same length. The several baffles distributed circumferentially can provide buffering for durians falling at different angles to ensure the buffering effect, and the baffles in the same group have the same length, so that the baffles closer to the bottom plate are closer to the center of the unloading cone, so that the several baffles in the same group can buffer the durian multiple times. When the durian passes through, the several baffles gradually adhere to its surface and buffer it multiple times again, gradually consuming its kinetic energy to avoid a single baffle from obtaining too much converted kinetic energy and being damaged.

[0022] Furthermore, a support rod is fixedly connected to one side of the unloading cone close to the bottom plate, an end of the support rod away from the unloading cone is fixedly connected to the inner side surface of the bottom plate, a support rod is fixedly connected to the surface of the support rod, an end of the support rod away from the support rod is fixedly connected to the top of the bottom plate, the support rod is provided to provide support for the bottom of the unloading cone to avoid deformation thereof and affect the passage of durian, the support rod is provided, and a triangular structure is formed between the support rod, the support rod and the bottom plate to further provide support.

[0023] Furthermore, the picking mechanism includes a support block, which is symmetrically arranged with the bottom plate as the center, and the two support blocks are fixedly connected to a telescopic column on one side close to the upper curtain, and a plate body is provided on the side of the telescopic column away from the support block, and the inner side surface of the plate body is fixedly connected to the surface of the telescopic column, and a guide plate is provided at the center of the plate body, and the surface of the guide plate is fixedly connected to the inner side surface of the plate body, and the guide plate is bent toward the side away from the center of the plate body, and a plurality of guide plates are provided on the circumference, and a plurality of guide plates are fixedly connected to a speed reduction strip on one side close to the bottom plate, and the speed reduction strip is made of elastic material, and the A plurality of deceleration strips are provided, and a picking component is fixedly connected to one side of the plate body away from the bottom plate. The telescopic column is started, and the telescopic column drives the plate body, the guide plate, the deceleration strip and the picking component to rise and fall. The picking component cuts the durian, and the durian falls and falls into the range of the circumferentially distributed guide plates. The durian contacts the guide plates and rolls down to the top of the upper curtain along the curved guide plates. The durian contacts the deceleration strip, and after the elastic deceleration strip contacts the durian, it contacts the thorny shell of the durian, thereby decelerating the durian and limiting the rotation of the durian, ensuring that the durian will not roll when it falls above the upper curtain, preventing the rolling durian from entangled with the canvas upper curtain, and ensuring that the durian can pass through the upper curtain smoothly.

[0024] Furthermore, the picking assembly includes a rotating seat, the rotating seat is fixedly connected to the side of the plate body away from the bottom plate, the rotating seat is rotatably connected to the rotating platform on the side away from the plate body, the rotating platform is rotatably connected to the first picking arm on the side away from the rotating seat through a rotating rod, the first picking arm is rotatably connected to the second picking arm on the side away from the rotating platform through the rotating rod, and the second picking arm is rotatably connected to the first picking arm at one end away from the first picking arm, the surface of the rotating telescopic rod is fixedly connected to the inner side surface of the second picking arm, the end of the rotating telescopic rod away from the second picking arm is fixedly connected to the picking seat, and the picking seat is symmetrically provided with a picking knife on the side away from the rotating telescopic rod, the surface of the picking knife is slidably connected to the inner side surface of the picking seat, the rotating seat, the rotating platform, the first picking arm and the second picking arm are started to adjust the picking height, the rotating telescopic rod is started, the rotating telescopic rod is telescoped and rotated, the picking position is further adjusted, the picking knife is driven to move, the durian is cut, and finally the durian falls.

[0025] The present invention has the beneficial effects:

[0026] 1. The present invention provides a buffer mechanism, and the buffer structures of the upper curtain, the lower curtain, and the lower material assembly are used to buffer the durian three times in sequence, so as to fully consume the kinetic energy converted from its gravitational potential energy, and avoid the durian from falling directly to the ground and causing damage. The segmented buffering can effectively reduce the reaction force on the durian, and further avoid the damage to the durian. A tightening assembly is provided to link the changes of the center holes of the upper curtain and the lower curtain. When the center hole of the upper curtain expands, the center hole of the lower curtain contracts, thereby ensuring that the durian can stably contact the lower curtain, thereby ensuring the stability of the second buffering. The center hole of the lower curtain expands, and the center hole of the upper curtain contracts, so that the durian is difficult to fly out from the gap between the upper curtain and the lower curtain, which can effectively avoid the durian from flying out and being damaged, and at the same time avoid injuring the operator nearby.

[0027] 2. The present invention sets an upper curtain and a lower curtain. The center hole of the upper curtain begins to relax, which can ensure the expansion of the durian when it falls, and the contraction after the durian passes through. The center hole of the lower curtain begins to contract, which can fully receive the durian when it falls, preventing the small durian from passing directly. The durian is more deformed after passing through, and the kinetic energy of the durian has to overcome the elastic force of the expansion of the lower curtain, so its kinetic energy can be consumed more effectively and a better buffering effect can be obtained.

[0028] 3. The present invention sets a tightening component, and the upper curtain expands, driving the first pull rod to move, driving the first connecting frame to move, and one end of the pull rope is relaxed, which puts the lower curtain in a semi-contracted state. The lower curtain loses the pulling force of the pull rope, causing the lower curtain to continue to contract, thereby tightening the pull rope. At the same time, the contracted lower curtain can effectively block the passage of durian. When the durian hits the lower curtain, the lower curtain expands, the second pull rod moves, driving the second connecting frame to move, and the other end of the pull rope is relaxed. Similarly, under the action of the elastic force of the expanded upper curtain, the pull rope is tightened again, and the upper curtain also contracts and returns to its original state, preventing the durian from rebounding and flying out.

[0029] 4. The present invention provides a material discharge component and several baffles distributed circumferentially, which can provide buffering for durian falling at different angles and ensure the buffering effect. The baffles in the same group have the same length, so that the baffles closer to the bottom plate are closer to the center of the material discharge cone, so that the several baffles in the same group can buffer the durian multiple times. When the durian passes through, several baffles gradually adhere to its surface and buffer it multiple times again, gradually consuming its kinetic energy, so as to avoid a single baffle from obtaining too much converted kinetic energy and being damaged.

[0030] 5. The present invention provides a picking mechanism. The durian contacts the guide plate and rolls down to the top of the upper curtain along the curved guide plate. The durian contacts the deceleration strip. After the elastic deceleration strip contacts the durian, it contacts the thorny shell of the durian, thereby decelerating the durian and limiting the rotation of the durian, ensuring that the durian does not roll when it falls above the upper curtain, preventing the rolling durian from entangled with the canvas upper curtain, and ensuring that the durian can pass through the upper curtain smoothly.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0044] Example 1, please refer to Figure 1-Figure 5 The present invention is a durian picking tool, comprising:

[0045] A bottom plate 1, the bottom of the bottom plate 1 is fixedly connected with a supporting leg 2, a plurality of supporting legs 2 are provided, and the plurality of supporting legs 2 are evenly distributed along the circumference of the bottom plate 1;

[0046] The buffer mechanism 3 is arranged on a side of the bottom plate 1 away from the supporting leg 2, and the buffer mechanism 3 is fixedly connected to the bottom plate 1;

[0047] A picking mechanism 5, which is arranged directly above the buffer mechanism 3 and is fixedly connected to the surface of the bottom plate 1;

[0048] Wherein, the buffer mechanism 3 comprises:

[0049] An upper curtain 31, which has a hole in the center and is made of canvas and is used to receive the cut durian;

[0050] A lower curtain 32, which has a hole in the center and is made of canvas, and is used to receive the durian dropped from the upper curtain 31 again;

[0051] A tightening assembly 33, which has a tensioning structure and is used to control the retraction and extension of the center holes of the upper curtain 31 and the lower curtain 32. The two side surfaces of the tightening assembly 33 are respectively fixedly connected to the inner side surfaces of the upper curtain 31 and the lower curtain 32, and the tightening assembly 33 is fixedly connected to the top of the bottom plate 1;

[0052] A material discharge assembly 34, which has a buffer structure and is used for buffering durian for the third time. The material discharge assembly 34 is arranged on a side of the lower curtain 32 close to the bottom plate 1, and the material discharge assembly 34 is fixedly connected to the top of the bottom plate 1;

[0053] When the durian is cut, it first falls on the top of the upper curtain 31, and the middle part of the upper curtain 31 is impacted, so that the central hole of the upper curtain 31 expands, and at the same time, one end of the tightening component 33 is relaxed, and the central hole of the lower curtain 32 shrinks. Then the durian falls to the top of the lower curtain 32, and the lower curtain 32 is impacted, and the central hole of the lower curtain 32 expands. On the contrary, the tightening component 33 controls the central hole of the upper curtain 31 to shrink. Finally, the durian passes through the lower curtain 32 and enters the inside of the unloading component 34. The unloading component 34 unloads the durian, and finally the durian falls to the bottom of the bottom plate 1. The buffer structures of the upper curtain 31, the lower curtain 32, and the unloading component 34 buffer the durian three times in turn, fully The kinetic energy converted from its gravitational potential energy is consumed to prevent the durian from falling directly to the ground and causing damage. The segmented buffering can effectively reduce the reaction force on the durian, further preventing the durian from being damaged. A tightening component 33 is provided to link the changes of the center holes of the upper curtain 31 and the lower curtain 32. When the center hole of the upper curtain 31 expands, the center hole of the lower curtain 32 contracts, thereby ensuring that the durian can stably contact the lower curtain 32, thereby ensuring the stability of the second buffering. The center hole of the lower curtain 32 expands and the center hole of the upper curtain 31 contracts, making it difficult for the durian to fly out from the gap between the upper curtain 31 and the lower curtain 32, which can effectively prevent the durian from flying out and being damaged, and at the same time avoid injuring the operator nearby.

[0054] There is a hole at a position of the supporting leg 2 away from the bottom plate 1, and an elliptical plate 4 is fixedly connected to the inner wall of the hole of the supporting leg 2. The elliptical plate 4 is made of elastic material. The elliptical plate 4 is arranged so that when the supporting leg 2 is subjected to pressure, the elliptical plate 4 is deformed, thereby achieving a buffering effect. The hollow structure of the elliptical plate 4 can conveniently provide fixation or counterweight for the supporting leg 2, which can effectively prevent the supporting leg 2 from rebounding under the reaction force of the falling durian, and prevent the receiving position of the bottom plate 1 from being offset.

[0055] The center hole of the upper curtain 31 is initially in a relaxed state, and the center hole of the lower curtain 32 is initially in a semi-expanded state, and the center hole of the upper curtain 31 is larger than the center hole of the lower curtain 32. The center hole of the upper curtain 31 just begins to relax, which can ensure the expansion when the durian falls, and the contraction after the durian passes through. The center hole of the lower curtain 32 just begins to contract, which can fully receive the durian when it falls, preventing the small durian from passing directly, and the degree of deformation after the durian passes through is greater. The kinetic energy of the durian has to overcome the elastic force of the expansion of the lower curtain 32, which can more effectively consume its kinetic energy and obtain a better buffering effect.

[0056] The tightening assembly 33 includes a first pull rod 331, which is arranged inside the upper curtain 31, and the surface of the first pull rod 331 is fixedly connected to the inner side surface of the upper curtain 31, and there are several first pull rods 331 evenly distributed along the circumference of the upper curtain 31, and a second pull rod 332 is arranged inside the lower curtain 32, and the surface of the second pull rod 332 is fixedly connected to the inner side surface of the lower curtain 32, and there are several second pull rods 332 evenly distributed along the circumference of the lower curtain 32. By pulling the first pull rod 331, several circumferentially arranged first pull rods 331 can achieve uniform expansion of the upper curtain 31, and by pulling the second pull rod 332, several circumferentially arranged second pull rods 332 can achieve uniform expansion of the lower curtain 32.

[0057] The first pull rod 331 is fixedly connected to the first connecting frame 333 at one end away from the center of the upper curtain 31, and the surface of the first connecting frame 333 is fixedly connected to the outermost inner side surface of the upper curtain 31. The second pull rod 332 is fixedly connected to the second connecting frame 334 at one end away from the center of the lower curtain 32, and the surface of the second connecting frame 334 is fixedly connected to the outermost inner side surface of the lower curtain 32. Both the first connecting frame 333 and the second connecting frame 334 are arranged in a bow shape. When the first pull rod 331 moves, it drives the first connecting frame 333 to move, and when the second pull rod 332 moves, it drives the second connecting frame 334 to move.

[0058] The first connecting frame 333 is located on the surface outside the upper curtain 31 and is fixedly connected to a pull rope 335. One end of the pull rope 335 away from the first connecting frame 333 is fixedly connected to the surface of the second connecting frame 334 located outside the lower curtain 32. A pulley 336 is provided on the side of the pull rope 335 away from the bottom plate 1. The outer side surface of the pulley 336 is transmission-connected to the surface of the pull rope 335. The inner side surface of the pulley 336 is rotationally connected to a mounting seat 337 through a rotating rod. The mounting seat 337 is fixedly connected to the side of the bottom plate 1 away from the supporting leg 2. The durian hits the upper curtain 31, and the upper curtain 31 expands, driving the first pull rod 331 to move, and the belt The first connecting frame 333 is moved, and one end of the pull rope 335 is relaxed, which means that the lower curtain 32 is in a semi-contracted state. The lower curtain 32 loses the pulling force of the pull rope 335, so that the lower curtain 32 continues to contract, thereby tightening the pull rope 335. At the same time, the contracted lower curtain 32 can effectively block the passage of the durian. When the durian hits the lower curtain 32, the lower curtain 32 expands, and the second pull rod 332 moves, driving the second connecting frame 334 to move, and the other end of the pull rope 335 is relaxed. Similarly, under the action of the elastic force restored by the expanded upper curtain 31, the pull rope 335 is tightened again, and the upper curtain 31 also contracts and returns to its original state to prevent the durian from rebounding and flying out.

[0059] Example 2, please refer to Figure 1-Figure 8 The unloading assembly 34 includes an unloading cone 341, which is arranged at the interval between the lower curtain 32 and the bottom plate 1. The side of the unloading cone 341 close to the bottom plate 1 is fixedly connected with a connecting leg 342, and the side of the connecting leg 342 away from the unloading cone 341 is fixedly connected to the side of the bottom plate 1 away from the supporting leg 2. The durian passes through the lower curtain 32 and then enters the unloading cone 341, and finally passes through the unloading cone 341 and the bottom plate 1 in sequence to complete the entire picking process.

[0060] A baffle 343 is provided inside the unloading cone 341. The baffle 343 is fixedly connected to the inner side surface of the unloading cone 341. The baffle 343 is made of elastic material and is naturally inclined inside the unloading cone 341. Before the durian contacts the unloading cone 341, it first hits the baffle 343, and the elastic baffle 343 is deformed, thereby further buffering and preventing the durian from being bumped.

[0061] Several groups of baffles 343 are arranged on the inner circumference of the unloading cone 341, and each group of baffles 343 is provided with several baffles 343, and the several baffles 343 are evenly distributed along the slope of the unloading cone 341, and the several baffles 343 have the same length. The several baffles 343 distributed circumferentially can provide buffering for durians falling at different angles to ensure the buffering effect, and the baffles 343 in the same group have the same length, so that the baffles 343 closer to the bottom plate 1 are closer to the center of the unloading cone 341, so that the several baffles 343 in the same group can buffer the durian multiple times. When the durian passes through, the several baffles 343 gradually adhere to its surface and buffer it multiple times again, gradually consuming its kinetic energy to avoid a single baffle 343 from obtaining too much converted kinetic energy and being damaged.

[0062] A support rod 344 is fixedly connected to one side of the unloading cone 341 close to the bottom plate 1, and one end of the support rod 344 away from the unloading cone 341 is fixedly connected to the inner side surface of the bottom plate 1, and a support rod 345 is fixedly connected to the surface of the support rod 344, and one end of the support rod 345 away from the support rod 344 is fixedly connected to the top of the bottom plate 1. The support rod 344 is provided to provide support for the bottom of the unloading cone 341 to prevent it from being deformed and affecting the passage of durian. The support rod 345 is provided, and a triangular structure is formed between the support rod 345, the support rod 344 and the bottom plate 1 to further provide support.
