Description

Technical Field

[0001] This invention relates to the field of forest fruit harvesting machinery technology, specifically to a forest fruit collection structure and a forest fruit harvesting machine with anti-piling function. Background Technology

[0002] With the large-scale development of the camellia oil industry, manual harvesting of camellia fruits is inefficient and costly. Camellia fruit harvesting machinery has become a key piece of equipment for industrial upgrading and is of great significance for improving production efficiency.

[0003] Existing camellia fruit collection devices typically use a vibrating mechanism to hold the tree trunk and vibrate it. After vibration, the camellia fruits fall downwards, and an umbrella-shaped collection hopper collects them. The collected fruits are then transported outwards by a conveyor belt at the bottom of the hopper. During vibration, a large number of fruits fall, and the conveyor belt cannot transport them quickly enough, leading to accumulation at the bottom of the collection hopper. This can cause fruits to fall off the conveyor belt edge or become stuck, hindering transport. Manual picking of fallen fruits and clearing of accumulated fruit are necessary to ensure smooth conveyor belt operation. Existing camellia fruit harvesting machinery not only increases labor intensity but also the risk of injury during operation.

[0004] In summary, there is an urgent need for a fruit and nut collection structure and a fruit and nut harvester with anti-piling function to solve or at least partially solve the problems existing in the prior art. Summary of the Invention

[0015] The application of the technical solution of the present invention has the following beneficial effects: During harvesting, this structure is moved to the camellia fruit tree, embedding the tree within a U-shaped clearance opening. The U-shaped frame then surrounds the tree, causing the camellia fruits to fall downwards. These fruits are collected by the collecting components and gathered at the guide components on either side, then conveyed to the conveying components. The large quantity of fruits is separated and guided by the collecting components to the guide components on either side of the U-shaped clearance opening, increasing the temporary storage area and reducing the probability of accumulation, thus preventing blockages. Simultaneously, the orderly conveying of the fruits to the conveying components prevents continuous accumulation, and the fruits are finally output from the conveying component's output end. This structural design prevents the camellia fruits from accumulating below the collecting components, preventing them from overflowing to the ground and causing blockages. This eliminates the need for manual cleaning, reducing the risk of accidents.

[0019] To facilitate understanding of the present invention, a more comprehensive description is provided below, along with preferred embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] Example: See Figures 1-8This embodiment provides a fruit collection structure with anti-piling function, including a Y-shaped frame 1, a collection component 2, a guiding component 3, and a conveying component 4. A U-shaped clearance opening 11 is provided at the front end of the Y-shaped frame 1. The collection component 2 is arranged on the top of the Y-shaped frame 1 to collect fallen fruit. Two sets of guiding components 3 are arranged, with the two sets of guiding components 3 respectively arranged on both sides of the U-shaped clearance opening 11. The inlet end of the guiding component 3 is connected to the outlet end of the collection component 2, and the outlet end of the guiding component 3 is connected to the inlet end of the conveying component 4. The conveying component 4 is installed on the Y-shaped frame 1 and is used to output and bag the fruit conveyed by the guiding component 3.

[0022] Research has revealed that existing camellia fruit collection devices typically employ a vibrating mechanism that holds the tree trunk and vibrates it. After vibration, the camellia fruits fall downwards, and an umbrella-shaped collection hopper collects them. Once collected, the fruits are transported outwards via a conveyor belt at the bottom of the hopper. During the vibration process, a large number of camellia fruits fall, and the conveyor belt cannot transport them quickly enough, leading to an accumulation of fruits at the bottom of the collection hopper. This can cause the fruits to fall off the conveyor belt edge or become stuck, hindering the transport process. Manual picking up of the fallen fruits and clearing of the accumulated fruit are necessary to ensure smooth conveyor belt operation.

[0023] It is understood that during harvesting, by moving this structure to the camellia fruit tree and embedding the tree within the U-shaped clearance opening 11, the U-shaped frame is arranged around the tree. The camellia fruits fall downwards and, under the collecting action of the collecting component 2, converge towards the guiding components 3 on both sides. The guiding components 3 then transport the fruits to the conveying component 4. A large number of camellia fruits are separated and guided by the collecting component 2 onto the guiding components 3 on both sides of the U-shaped clearance opening 11, expanding the temporary storage area and reducing the probability of accumulation, thus preventing blockages. Simultaneously, the guiding components 3 orderly transport the fruits to the conveying component 4, preventing continuous accumulation, and finally outputting them from the output end of the conveying component 4. Through the design of this structure, the accumulation of camellia fruits under the collecting component 2 is avoided, preventing them from overflowing to the ground and preventing blockages caused by accumulation. This eliminates the need for manual cleaning of blockages and reduces the occurrence of safety accidents.

[0024] It should be noted that, in addition to being applicable to camellia fruit, the above-mentioned equipment can also be applied to other fruits that bear fruit on trees, such as bayberry, cherry, and sweet cherry.

[0025] Preferably, the material collection assembly 2 includes two sets of umbrella-shaped material collection components 21, which are respectively arranged on both sides of the Y-shaped frame 1. Each umbrella-shaped material collection component 21 unfolds to form half of an umbrella, and the two sets of umbrella-shaped material collection components 21 are joined together to form an umbrella-shaped material collection hopper. Each umbrella-shaped material collection component 21 includes a first driving component 211, an active support rod 212, a floating support rod 213, and a guide cloth 214. The active support rod 212 is rotatably connected to the opening end of the Y-shaped frame 1 near the U-shaped clearance opening 11 via a bearing, and its rotation axis is arranged vertically. The first driving component 211 is installed inside the Y-shaped frame 1 and is used to drive the active support rod 212 to rotate. The floating support rod 213... Two floating support rods 213 are arranged, and both floating support rods 213 are rotatably connected to the side of the Y-shaped frame 1 by bearings. Their rotation axis is arranged vertically, and the floating support rods 213 can rotate freely on the Y-shaped frame 1. The active support rod 212 and the two floating support rods 213 are bent away from the U-shaped clearance opening 11 to form an umbrella-shaped frame structure with the opening facing upward. The first end of the guide cloth 214 is detachably connected to the active support rod 212, the middle part of the guide cloth 214 is connected to the two floating support rods 213, and the second end of the guide cloth 214 is detachably connected to the side wall of the Y-shaped frame 1 away from the U-shaped clearance opening 11.

[0026] With the above structural design, when the trunk of the camellia fruit tree needs to be inserted into the U-shaped clearance opening 11, the two first driving members 211 on both sides of the U-shaped clearance opening 11 drive the corresponding active support rods 212 to rotate, thereby causing the two active support rods 212 to rotate to both sides, so that a clearance groove is formed between the two active support rods 212, so that the camellia fruit tree can smoothly enter the U-shaped clearance opening 11. At this time, the guide cloth 214 is in a folded state. After the camellia fruit tree enters the U-shaped clearance opening 11, the two active support rods 212 are driven to rotate in opposite directions to close the clearance groove between the two active support rods 212. At this time, the guide cloth 214 is in an unfolded state, and the two sets of umbrella-shaped collecting members 21 form a complete umbrella-shaped collecting hopper. The camellia fruit tree is located in the center of the umbrella-shaped collecting hopper, so that the camellia fruits falling from the camellia fruit tree are guided by the guide cloth 214 and gather towards the center.

[0027] Specifically, the first driving component 211 includes a hydraulic cylinder 2111, a rack 2112, and a gear 2113. The gear 2113 is coaxially and fixedly connected to one end of the active support rod 212 located in the Y-shaped frame 1. The rack 2112 is slidably connected to the Y-shaped frame 1. The gear 2113 meshes with the rack 2112. When the rack 2112 slides relative to the Y-shaped frame, it drives the gear 2113 and the active support rod 212 fixedly connected to the gear 2113 to rotate, thereby unfolding or folding the umbrella-shaped material collector 21.

[0028] It can be understood that by controlling the extension or retraction of the hydraulic cylinder 2111, the rack 2112 is pushed to slide back and forth on the Y-shaped frame 1. The rack 2112 drives the gear 2113 and the active support rod 212 to rotate, that is, the hydraulic cylinder 2111 controls the rotation of the active support rod 212.

[0029] Preferably, the material guiding assembly 3 includes a belt conveyor 31, a screw conveyor 32, and a second drive 33. The belt conveyor 31 is arranged along the edge of the U-shaped clearance opening 11. The inlet end of the screw conveyor 32 is connected to the outlet end of the belt conveyor 31, and the outlet end of the screw conveyor 32 is connected to the inlet end of the conveying assembly 4. The second drive 33 is mounted on the Y-shaped frame 1 and is used to drive the belt conveyor 31 and the screw conveyor 32 to rotate synchronously. Specifically, the second drive 33 can be two separate motors, which drive the belt conveyor 31 and the screw conveyor 32 to move respectively, or a transmission structure consisting of a motor, a sprocket, and a chain can drive the belt conveyor 31 and the screw conveyor 32 to move simultaneously.

[0030] It is understood that the camellia fruits collected by the hopper fall onto both sides of the U-shaped clearance opening 11. The guide assembly 3 receives the camellia fruits and conveys them towards the screw conveyor 32 via the belt conveyor 31, preventing the camellia fruits from accumulating on the belt conveyor 31. Simultaneously, the camellia fruits conveyed to the screw conveyor 32 are conveyed towards the conveying assembly 4 under the action of the screw conveyor 32, and finally output from the discharge end of the conveying assembly 4. The second drive component 33 simultaneously drives the belt conveyor 31 and the screw conveyor 32 to operate, preventing material accumulation at the junction of the belt conveyor 31 and the screw conveyor 32 due to asynchronous operation.

[0031] Preferably, two leak-proof rubber plates are installed on the Y-shaped frame. These two plates are fixedly connected to both sides of the U-shaped clearance opening 11, covering the opening. A receiving hole is provided between the two plates, into which the camellia fruit tree is inserted during harvesting. The leak-proof rubber plates block the U-shaped clearance opening 11, preventing the camellia fruit from falling to the ground while allowing the tree to be easily inserted. Lips are provided on both sides of the leak-proof rubber plates, which are inclined away from the receiving hole. These lips prevent the fruit from rolling off the sides and onto the ground, while also guiding the fruit towards the belt conveyor 31 in the guide assembly under gravity. The Y-shaped frame is equipped with guide surfaces, and multiple guide surfaces are arranged around the material guiding component 3 to guide the camellia fruit and move it toward the belt conveyor 31 in the material guiding component 3, thus preventing the camellia fruit from accumulating.

[0032] Preferably, the belt conveyor 31 includes a first driving roller 311, a first driven roller 312, and a first conveyor belt 313. The first driving roller 311 and the first driven roller 312 are rotatably connected to the Y-shaped frame 1 in parallel with each other, and the first conveyor belt 313 is wound around both the first driving roller 311 and the first driven roller 312. The first output end of the second drive member 33 is connected to the first driving roller 311. Specifically, the first driving roller 311 and the first driven roller 312 are rotatably connected inside the Y-shaped frame 1 so that the first conveyor belt 313 is arranged below the surface of the Y-shaped frame 1, so that the camellia fruit can be collected on the first conveyor belt 313, facilitating the conveying of the camellia fruit.

[0033] It is known that the second driving member 33 drives the first active roller 311 to rotate, which in turn drives the first driven roller 312 and the conveyor belt to rotate, conveying the camellia fruit located on the first conveyor belt 313 toward the spiral conveyor 32.

[0034] Preferably, the spiral conveyor 32 includes a spiral blade 321 and a guide cover 322. The spiral blade 321 is rotatably connected to the Y-shaped frame 1 and is arranged along a conveying direction perpendicular to the first conveyor belt 313. The second output end of the second drive member 33 is connected to the spiral blade 321. The guide cover 322 is fixedly connected to the Y-shaped frame 1 and covers the outer periphery of the spiral blade 321. An opening for the fruit to enter is provided on the side of the guide cover 322 near the first conveyor belt 313.

[0035] It is known that under the conveying action of the first conveyor belt 313, the camellia fruit enters the space between the spiral blades 321 from the opening. The second driving member 33 drives the spiral blades 321 to rotate. When the spiral blades 321 rotate, they push the camellia fruit to move along the guide cover 322 toward the conveying assembly 4 and are discharged onto the conveying assembly 4.

[0036] By combining the belt conveyor 31 and the spiral conveyor 32, the camellia fruits gathered on the belt conveyor 31 are promptly collected from both sides of the Y-shaped frame to the conveying assembly 4, preventing the camellia fruits from accumulating on both sides of the Y-shaped frame and causing them to overflow, or preventing the conveying assembly 4 used to transport the camellia fruits from jamming and damaging the equipment due to the accumulation of camellia fruits, thus reducing the labor intensity of the operators and the probability of danger.

[0037] Preferably, the conveying assembly 4 includes a second driving roller 41, a second driven roller 42, a second conveyor belt 43, a partition 44, and a baffle 45. The second driving roller 41 and the second driven roller 42 are rotatably connected to the Y-shaped frame 1 in parallel with each other. The second conveyor belt 43 is simultaneously wound around the second driving roller 41 and the second driven roller 42. The third output end of the second drive member 33 is connected to the second driving roller 41. The partition 44 is fixedly connected to the outer surface of the second conveyor belt 43, and the partition 44 is arranged along the width direction of the second conveyor belt 43. Multiple partitions 44 are arranged, and the multiple partitions 44 are arranged at intervals around the outer periphery of the second conveyor belt 43. Two baffles 45 are arranged, and the two baffles 45 are respectively fixedly connected to both sides of the second conveyor belt 43.

[0038] It should be noted that during collection, the end of the Y-shaped frame 1 closest to the U-shaped clearance opening 11 needs to be close to the ground, while the output end of the conveying component 4 needs to have a certain height in order to facilitate bagging. Therefore, the end of the Y-shaped frame away from the U-shaped clearance opening 11 is arranged to be curved upwards, and the conveying component 4 is installed on the curved end of the Y-shaped frame.

[0039] It is understood that the second driving component 33 drives the second active roller 41 to rotate, which in turn drives the second conveyor belt 43 and the second driven roller 42 to rotate. During operation, the second conveyor belt 43 transports the camellia fruit conveyed by the spiral conveyor 32 upwards along the Y-shaped frame. Because the second conveyor belt 43 is inclined, and the camellia fruit is spherical, the fruit will roll downwards along the conveyor belt 43 during transport, causing the conveyor belt to be obstructed. Therefore, a partition 44 is installed. The partition 44 acts as a barrier to prevent the camellia fruit from rolling along the conveyor belt 43, ensuring smooth transport. Simultaneously, baffles 45 are installed on both sides of the second conveyor belt 43 to prevent the camellia fruit from falling off the conveyor belt.

[0040] Preferably, the conveying assembly 4 further includes a discharge hopper 46, which has an inlet 461 and two outlets 462. The discharge hopper 46 is fixedly connected to the end of the Y-shaped frame 1 away from the U-shaped clearance opening 11. The inlet 461 is arranged to be connected to the discharge end of the conveying assembly 4, and the two outlets 462 are respectively led out towards the two sides of the discharge hopper 46.

[0041] It is understood that by setting two discharge ports 462 on both sides of the discharge hopper 46 to discharge material simultaneously, the discharge pressure of the discharge hopper 46 is relieved and the camellia fruit is prevented from accumulating at the discharge hopper 46. At the same time, the arrangement of the discharge ports from both sides makes it convenient to collect the camellia fruit using collection boxes or collection bags.

[0042] Preferably, the discharge hopper 46 has a baffle 463, which is fixedly connected to the top of the discharge hopper 46 and is arranged at the inlet 461 of the discharge hopper 46.

[0043] It is known that because the conveyor belt is arranged at an upward inclination, when the conveyor belt is conveying the camellia fruit, the camellia fruit output from the discharge end of the conveyor belt has an upward speed, which makes it difficult for the camellia fruit to accurately enter the feed port 461 of the discharge hopper 46, causing the camellia fruit to fly out; however, by arranging the baffle 463, the baffle 463 blocks and guides the camellia fruit, so that all the camellia fruit is accurately guided into the discharge hopper 46, preventing the camellia fruit from flying out.

[0044] Preferably, the discharge hopper 46 has hanging teeth 464, which are fixedly connected to the discharge port 462 of the discharge hopper 46 and are arranged facing upwards; multiple hanging teeth 464 are arranged at intervals around the outer periphery of the discharge port 462. The arrangement of the hanging teeth 464 facilitates the attachment of nylon bags for packaging camellia oil fruits.

[0045] Preferably, the second driving component 33 includes a drive motor 330, a first sprocket 331, a first chain 332, a second sprocket 333, a third sprocket 334, a second chain 335, a fourth sprocket 336, a fifth sprocket 337, a third chain 338, and a sixth sprocket 339. The drive motor 330 is mounted on the Y-shaped frame 1. The first sprocket 331 is coaxially fixedly connected to the output shaft of the drive motor 330. The second sprocket 333 and the third sprocket 334 are coaxially fixedly connected to the second drive roller 41. Chain 332 is wound around the first sprocket 331 and the second sprocket 333; the fourth sprocket 336 and the fifth sprocket 337 are both coaxially fixedly connected to the first drive roller 311, and the second chain 335 is wound around the third sprocket 334 and the fourth sprocket 336 at the same time. The fourth sprocket 336 and the fifth sprocket 337 are respectively arranged at both ends of the first drive roller 311; the sixth sprocket 339 is coaxially fixedly arranged with the helical blade 321, and the third chain 338 is wound around the fifth sprocket 337 and the sixth sprocket 339 at the same time.

[0046] Specifically, the drive motor 330 rotates, causing the first sprocket 331 to rotate. The first sprocket 331, through the first chain 332, drives the second sprocket 333, the third sprocket 334, and the second drive roller 41 to rotate. When the second drive roller 41 rotates, it drives the second conveyor belt 43 and the second driven roller 42 to rotate, so as to transport the camellia fruit. When the third sprocket 334 rotates, it drives the fourth sprocket 336, the fifth sprocket 337, and the spiral blade 321 to rotate through the second chain 335. When the spiral blade 321 rotates, it pushes the camellia fruit from the first conveyor belt 313 toward the second conveyor belt 43. When the fifth sprocket 337 rotates, it drives the sixth sprocket 339 and the first drive roller 311 to rotate through the third chain 338. When the first drive roller 311 rotates, it drives the first conveyor belt 313 and the first driven roller 312 to rotate. The first conveyor belt 313 transports the camellia fruit toward the spiral blade 321 to prevent the camellia fruit from accumulating.

[0047] It is understood that, through the design of the above structure, the second drive component 33 drives other accessories to move through the motor, and can simultaneously drive the first drive roller 311, the spiral blade 321 and the second drive roller 41 to move synchronously, thereby making the belt conveyor 31, the spiral conveyor 32 and the conveying assembly 4 move synchronously, preventing one of the components from moving first and causing the camellia fruit to accumulate between two adjacent components.

[0048] The working principle and basic operation process of this invention are as follows: Initially, the two active support rods 212 are separated, and the guide cloth 214 is folded. The U-shaped frame is moved to the camellia fruit tree, embedding it into the U-shaped clearance opening 11. The two first drive units 211 simultaneously drive the two active support rods 212 to rotate in opposite directions, causing them to overlap. At this point, the two guide cloths 214 are fully unfolded, forming an umbrella-shaped bucket with the opening facing upwards. The camellia fruit falls onto the guide cloths 214, which cushion and guide it, guiding it to the belt conveyors 31 on both sides of the U-shaped clearance opening 11. The second drive unit 33 then operates, driving the first active roller 311. The rotation of the first conveyor belt 313 causes it to move toward the spiral conveyor blades. The second drive unit 33 simultaneously drives the spiral blades 321 to rotate, so as to transport the camellia fruit from the first conveyor belt 313 to the conveying assembly 4. The two sets of spiral conveyor blades simultaneously transport the camellia fruit toward the conveying assembly 4 in the middle. The second drive unit 33 drives the second drive roller 41 to rotate, which in turn drives the second conveyor belt 43 to operate. The camellia fruit from the two sets of spiral blades 321 is transported to the hopper 46 through the second conveyor belt 43 and finally discharged from the two discharge ports 462 of the discharge hopper 46 for bagging.

[0049] Reference Figure 9 and Figure 10This application also provides a fruit harvester, including a walking mechanism 5, a vibration mechanism 6, and a connecting assembly 7. It also includes the aforementioned fruit collection structure with anti-piling function, which is mounted on the walking mechanism 5. The vibration mechanism 6 is floatingly mounted on the Y-shaped frame 1 via the connecting assembly 7. The connecting assembly 7 includes three sets of chain connectors 71, the tops of which are connected to the Y-shaped frame 1, and the bottoms of which are connected to the vibration mechanism 6. Each chain connector 71 includes a chain 71. 1. Adjusting bolt 712, nut 713, buffer sleeve 714 and buffer washer 715. The first end of the chain 711 is connected to the vibration mechanism 6, and the second end of the chain 711 is connected to the adjusting bolt 712. A through hole is provided on the Y-shaped frame 1. The adjusting bolt 712 passes through the through hole upward and is connected to the nut 713. The buffer sleeve 714 and the buffer washer 715 are both sleeved on the adjusting bolt 712, and the bottom of the buffer sleeve 714 abuts against the Y-shaped frame 1. The buffer washer 715 is placed between the buffer sleeve 714 and the nut 713. Specifically, the vibration mechanism 6 includes a mounting frame 61, a fixed arm 62, a clamping arm 63, a clamping cylinder 64, and a vibration motor 65. The mounting frame 61 is suspended from the Y-shaped frame 1 via three sets of chain connectors 71. The fixed arm 62 is detachably connected to the mounting frame 61. Two clamping arms 63 are arranged, each hinged to the fixed frame, and located on opposite sides of the fixed arm 62. Two clamping cylinders 64 are arranged corresponding to the clamping arms 63. The first end of each clamping cylinder 64 is hinged to the fixed frame, and the second end is hinged to the clamping arm 63. When the two clamping cylinders 64 are working, they push the two clamping arms 63 to rotate towards the center to clamp or to rotate outward to release. The vibration motor 65 is mounted on the fixed frame to provide vibration energy to the fixed frame. It is understood that the vibration assembly is suspended and connected via three sets of chain connectors 71. When the vibration assembly clamps the camellia fruit tree and vibrates, because the three sets of chain connectors 71 are flexible connections, they cannot transmit vibration waves laterally. Therefore, all the vibration energy generated by the vibration assembly is transferred to the camellia fruit tree, thus fully utilizing the vibration energy. Secondly, the vibration is isolated by the three sets of chain connectors 71, preventing the vibration generated by the vibration assembly from damaging other working parts, thereby improving service life. The buffer sleeve 714 reduces vibration along the chain direction; and the adjustment bolt 712 and nut 713 allow for fine-tuning in the height direction.

[0050] Specifically, the traveling mechanism 5 is a tracked traveling mechanism 5, on which a height adjusting cylinder 51 and an angle adjusting cylinder 52 are hinged. The tracked traveling mechanism 5 also has a connecting frame 53, with its first end hinged to the tracked traveling mechanism 5 and its second end hinged to the Y-shaped frame 1. The first end of the height adjusting cylinder 51 is hinged to the tracked traveling mechanism 5, and its second end is hinged to the connecting frame 53. Similarly, the first end of the angle adjusting cylinder 52 is hinged to the connecting frame 53, and its second end is hinged to the Y-shaped frame 1. The height adjusting cylinder 51 raises and lowers the Y-shaped frame 1, while the angle adjusting cylinder 52 extends and retracts to adjust the angle of the Y-shaped frame 1.

[0051] The working principle and basic operation process of this invention are as follows: Initially, the two active support rods 212 are separated, and the guide cloth 214 is folded. During operation, the walking mechanism 5 moves the entire device toward the camellia fruit tree to be harvested. The position and angle of the Y-shaped frame 1 are adjusted by the height adjustment cylinder 51 and the angle adjustment cylinder 52, allowing the camellia fruit tree to be embedded in the U-shaped clearance opening 11 of the Y-shaped frame 1. The clamping cylinder in the vibration mechanism 6 actuates, clamping the camellia fruit tree through the fixed arm 62 and two clamping arms, thus holding the vibration mechanism 6 onto the tree. The two first driving components 211 simultaneously drive the two active support rods 212 to rotate in opposite directions, causing them to overlap. At this point, the two guide cloths 214 are fully unfolded, forming an umbrella-shaped bucket with the opening facing upwards. The vibration motor 65 in the vibration mechanism 6 operates, causing the camellia fruit tree to vibrate, shaking the fruit off the tree. The fruit falls onto the guide cloth 214. The guide cloth 214 acts as a buffer and guide for the camellia fruit, which is then guided to the belt conveyors 31 on both sides of the U-shaped clearance opening 11. The second drive unit 33 operates, driving the first active roller 311 to rotate, which in turn drives the first conveyor belt 313 to move towards the spiral conveyor blades. At the same time, the second drive unit 33 drives the spiral blades 321 to rotate, so as to transport the camellia fruit transported by the first conveyor belt 313 to the conveying assembly 4. Both sets of spiral conveyor blades simultaneously transport the camellia fruit towards the central conveying assembly 4. The second drive unit 33 drives the second active roller 41 to rotate, which in turn drives the second conveyor belt 43 to operate. The second conveyor belt 43 transports the camellia fruit transported by the two sets of spiral blades 321 to the hopper 46, and finally discharges it from the two discharge ports 462 of the hopper 46 for bagging.
