Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable harvesting technology, and in particular to an integrated device for fruit and vegetable buffering, grading, and netting. Background Technology

[0002] Existing harvesting machines can be referenced from the patent with application number 2019205073577, which includes a harvesting mechanism, a buffer mechanism, a conveying mechanism, and a fruit box. After the harvesting mechanism picks up the fruits and vegetables, the fruits and vegetables enter the buffer mechanism for buffering, and the conveying mechanism sends the fruits and vegetables in the buffer mechanism into the fruit box.

[0003] Existing harvesting machines do not have a netting function. After harvesting, the fruits and vegetables need to be manually removed from the fruit box and then netted, which is time-consuming and labor-intensive. Summary of the Invention

[0004] To address the shortcomings of existing harvesters that lack netting functionality, this invention proposes an integrated device for fruit and vegetable buffering, grading, and netting, which can grade and net the fruits and vegetables harvested by the harvester.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The netting covers the fruits and vegetables; the netting mechanism includes a main body, support parts, and adjustment components. The main body is vertically positioned above the fruit-supporting component. Several support parts are rotatably connected to the lower end of the main body. The adjustment components can drive the support parts to rotate outward or inward according to the outer diameter of the fruits and vegetables to adjust the size of the netting opening. The power component can drive the netting to move downward along the main body to cover the fruits and vegetables. The net-cutting component is located between the main body and the fruit-supporting component and can cut the netting. The unloading mechanism can discharge the fruits and vegetables that have been netted by the netting mechanism.

[0007] With the above setup, firstly, after the harvester picks the fruits and vegetables, the netting mechanism covers the fruits and vegetables with nets, saving labor; secondly, the grading mechanism grades the fruits and vegetables, and the machine core can adjust the size of the net opening to match the outer diameter of the fruits and vegetables, and finally cover the fruits and vegetables with nets.

[0008] Furthermore, the grading mechanism is set up as a vision system, which is positioned above the conveying path of the fruit-feeding mechanism and can take downward photos of the fruits and vegetables.

[0009] Furthermore, the fruit-supporting assembly includes: a rotating base, a lifting tray for supporting fruits and vegetables, a guide rod, a lifting component, and a rotating device; several lifting trays are arranged around the circumference of the rotating base, one of which is close to the output end of the fruit-feeding mechanism, and another is located directly below the core mechanism; the guide rod is vertically installed on the upper side of the rotating base, passes through the lifting tray, and is slidably connected to the lifting tray; the lifting component can drive the lifting tray directly below the core mechanism to move up and down; the rotating device is connected to the rotating base and can drive the rotating base to rotate around its center, so that the fruits and vegetables are close to or leave from the bottom of the core mechanism.

The first pulleys are rotatably connected to the support base. The sliding base of one power roller assembly is connected to the upper side of the first synchronous belt, and the sliding base of the other power roller assembly is connected to the lower side of the first synchronous belt. The first motor has torque feedback and automatic brake functions.

[0012] With the above settings, firstly, the first motor can control the power roller to move closer to or further away from the core without manual adjustment, making it convenient to connect the core to the grid; secondly, when the power roller squeezes the core, the torque of the first motor increases, and when the torque reaches the preset value, the first motor can automatically engage the brake to make the clamping force of the power roller on the core moderate; thirdly, the first motor can drive the movement of two power roller assemblies simultaneously.

[0014] With the above configuration, the second motor can drive the hot melt wire to reciprocate via the second synchronous belt. When the hot melt wire passes through the mesh sleeve, it can cut the mesh sleeve.

[0015] Furthermore, an integrated fruit and vegetable buffering, grading, and netting device also includes a counting mechanism; the counting mechanism includes: a base, a drive roller, an encoder, a driven roller, and a clamping mechanism; the base is positioned above the core mechanism, and has a through hole through which the netting can pass; the drive roller is rotatably connected to the base; the encoder is mounted on the base and can calculate the number of rotations of the drive roller; the driven roller is arranged parallel to the drive roller; the clamping mechanism includes a mounting plate, a second slider, a fixing block, and a spring; the mounting plate is mounted on the base, the second slider is slidably connected to the mounting plate, the end of the driven roller is rotatably connected to the second slider, the fixing block is fixedly connected to the mounting plate, and the spring is installed between the fixing block and the second slider so that the driven roller presses the netting tightly onto the drive roller.

[0016] The above settings achieve the following: First, they facilitate internet access; second, the driving and driven rollers can stably clamp the mesh sleeve, preventing it from loosening; and third, they employ encoder counting, resulting in high counting accuracy.

[0017] Furthermore, the buffer mechanism includes: a frame, a turntable, a first drive mechanism, fruit racks, and a tilting mechanism; the frame is installed in the harvester; two turntables are rotatably connected in the frame, and the two turntables are arranged opposite each other; the first drive mechanism is installed on the frame and can drive the turntables to rotate; several fruit racks are horizontally rotatably connected between the turntables, and the fruit racks are provided with fruit troughs for placing fruits and vegetables.

[0020] Furthermore, one of the turntables has a clearance hole at its center, and one end of the feeding cylinder passes through the clearance hole to extend to the outside of the turntable; the receiving space includes a receiving section located on the outside of the turntable and a discharging section located between the two turntables; the feeding mechanism is located on the outside of the turntable to deliver the fruits and vegetables output by the harvester into the receiving section; the feeding mechanism also includes: a push plate, a push rod, and a third drive mechanism; the push plate is located inside the receiving section; one end of the push rod is connected to the push plate, and the other end of the push rod faces away from the discharging section and extends to the outside of the feeding cylinder; the third drive mechanism is mounted on the frame and can drive the push plate through the push rod to push the fruits and vegetables in the receiving section into the discharging section.

[0021] The above settings facilitate the feeding mechanism's delivery of fruits and vegetables from the outside to the inside of the buffer mechanism, and also facilitate the installation of the feeding mechanism.

[0022] Furthermore, the fruit feeding mechanism also includes a stop block, which is installed in the fruit feeding cylinder and positioned between the fruit receiving part and the fruit discharging part. Fruits and vegetables can roll over the upper side of the stop block into the fruit discharging part under the action of the push plate.

[0023] The above settings can prevent fruits and vegetables entering the fruit outlet from rolling back into the fruit outlet. Attached Figure Description

[0033] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0034] See Figures 1 to 9 An integrated fruit and vegetable buffering, grading, and netting device includes: a buffering mechanism 4, a feeding mechanism 5, a conveying mechanism 6, a grading mechanism 7, a netting mechanism 8, and a fruit unloading mechanism 9. The buffering mechanism 4 can store multiple fruits and vegetables. The feeding mechanism 5 can guide fruits and vegetables picked by a harvester into the buffering mechanism 4. The conveying mechanism 6 can output the fruits and vegetables from the buffering mechanism 4. The grading mechanism 7 is located on the conveying path of the conveying mechanism 6 and can detect the outer diameter of the fruits and vegetables for grading. The netting mechanism 8 includes a fruit-supporting component 81, a mechanism 82, a net (not shown in the figure), a power component 83, and a net-cutting component 84. The fruit-supporting component 81 can receive the output from the conveying mechanism 6. Fruits and vegetables; a net is fitted onto the mechanism 82, which includes a mechanism body 821, a support part 822, and an adjustment component. The mechanism body 821 is vertically positioned above the fruit-supporting component 81. Several support parts 822 are rotatably connected to the lower end of the mechanism body 821. The adjustment component can drive the support parts 822 to rotate outward or inward according to the outer diameter of the fruits and vegetables to adjust the size of the net opening. The power component 83 can drive the net to move downward along the mechanism 82 to fit the net onto the fruits and vegetables. The net-cutting component 84 is positioned between the mechanism 82 and the fruit-supporting component 81 and can cut the net. The fruit-unloading mechanism 9 can discharge the fruits and vegetables that have been netted by the net-fitting mechanism 8.

[0035] With the above settings, firstly, after the harvester picks the fruits and vegetables, the netting mechanism 8 puts a net over the fruits and vegetables, saving labor; secondly, the grading mechanism 7 grades the fruits and vegetables, and the mechanism 82 can adjust the size of the net opening to match the outer diameter of the fruits and vegetables, and finally put the net over the fruits and vegetables.

[0036] In this application, the fruit feeding mechanism 5 can be a conveying mechanism such as an auger roller; one end of the fruit feeding mechanism 5 extends towards the buffer mechanism 4. After the fruit feeding mechanism 5 is running, it can guide the fruits and vegetables picked by the harvester into the buffer mechanism 4. The buffer mechanism 4 can refer to the harvester in the background art; the fruit conveying mechanism 6 can be in the form of a conveyor belt or an auger roller, etc. One end of the fruit conveying mechanism 6 extends towards the fruit holding assembly 81. The fruit conveying mechanism 6 conveys the fruits and vegetables in the buffer mechanism 4 to the fruit holding assembly 81. When the fruits and vegetables pass through the grading mechanism 7, the grading mechanism 7 detects the outer diameter of the fruits and vegetables and divides them into several grades according to the outer diameter; in this application, the lower end of the support part 822 is inclined outward. When the net sleeve moves downward along the core 82, the support... The support part 822 opens the opening of the net sleeve. When the adjusting mechanism drives the support part 822 to rotate outward, the opening of the net sleeve output by the mechanism 82 increases; when the adjusting mechanism drives the support part 822 to rotate inward, the opening of the net sleeve output by the mechanism 82 decreases. The adjusting mechanism can be a motor or similar device. The adjusting mechanism drives the support part 822 to rotate outward or inward according to the grade of the fruits and vegetables to adjust the size of the net sleeve opening, ensuring the diameter of the opening matches the outer diameter of the fruits and vegetables. The power component 83 drives the net sleeve downward to cover the fruits and vegetables. After the net-cutting component 84 cuts the net sleeve between the fruits and vegetables and the mechanism 82, the fruit-unloading mechanism 9 discharges the fruits and vegetables that have been netted from the fruit-supporting component 81. As one implementation, the fruit-unloading mechanism 9 can be found in [reference needed]. Figure 4 The unloading mechanism 9 includes an unloading motor 91 and a lever 92. The unloading motor 91 is connected to the lever 92. A fruit discharge trough 10 is provided below the unloading mechanism 9. A fruit-topping device 11 is provided at one end of the fruit discharge trough 10, and a finished product outlet 12 is provided at the other end of the fruit discharge trough 10. The fruit-topping device 11 can be in the form of an electric cylinder or the like. After the fruits and vegetables are netted on the lifting tray 812, the unloading motor 91 drives the lever 92 to rotate. The lever 92 can push the netted fruits and vegetables from the lifting tray 812 into the fruit discharge trough 10. The fruit-topping device 11 pushes the fruits and vegetables forward. The fruits and vegetables roll along the fruit discharge trough 10 and are finally output from the finished product outlet 12.

[0037] As one implementation method, the grading mechanism 7 is set as a vision system, which is positioned above the conveying path of the fruit delivery mechanism 6 and can take downward photos of the fruits and vegetables.

[0038] In this application, a gantry is provided above the fruit delivery mechanism 6. The vision system includes a camera, which can be purchased from the market. The camera is mounted on the gantry and the shooting direction is downward. When the fruit and vegetables pass under the camera, the camera takes pictures of the fruit and vegetables, and the outer diameter of the fruit and vegetables is measured after image processing.

[0039] In one implementation, the fruit-supporting assembly 81 includes: a rotating base 811, a lifting tray 812 that can support fruits and vegetables, a guide rod 813, a lifting assembly (not shown in the figure), and a rotating device (not shown in the figure); a plurality of lifting trays 812 are arranged around the circumference of the rotating base 811, one of the lifting trays 812 is close to the output end of the fruit-feeding mechanism 6, and another lifting tray 812 is located directly below the core mechanism 82; the guide rod 813 is vertically installed on the upper side of the rotating base 811, the guide rod 813 passes through the lifting tray 812 and is slidably connected to the lifting tray 812; the lifting assembly can drive the lifting tray 812 directly below the core mechanism 82 to move up and down; the rotating device is connected to the rotating base 811 and can drive the rotating base 811 to rotate around its center, so that the fruits and vegetables are close to the bottom of the core mechanism 82 or leave from the bottom of the core mechanism 82.

[0040] With the above settings, firstly, the netting of fruits and vegetables and the feeding of fruits by the fruit feeding mechanism 6 can be carried out simultaneously, improving the efficiency of netting; secondly, the lifting component can drive the lifting tray 812 to move upward, so that the fruits and vegetables are closer to the core 82, making it easier to net them.

[0041] In this application, the rotating seat 811 is circular and horizontally installed in the harvester; the number of lifting trays 812 is set to four, and they are evenly arranged around the circumference of the rotating seat 811; the guide rod 813 plays a guiding role, so that the lifting trays 812 move up and down stably; one of the lifting trays 812 is close to the output end of the fruit feeding mechanism 6, which is convenient for receiving the fruits and vegetables output by the fruit feeding mechanism 6; after the lifting tray 812 receives the fruits and vegetables, the rotating device drives the rotating seat 811 to move the fruits and vegetables to the netting mechanism 8 for netting, while at the same time, the other lifting tray 812 rotates to the output end of the fruit feeding mechanism 6 to continue to receive fruits and vegetables; the fruit feeding mechanism 6 and the netting mechanism 8 perform the netting at the same time, which can improve the overall netting efficiency. When the netting mechanism 8 sets the net, the lifting component drives the lifting tray 812 to move upward, so that the fruits and vegetables are closer to the core 82, reducing the netting length between the fruits and vegetables and the core 82, which can reduce the waste of the netting. After the netting component 84 cuts the netting, the lifting component drives the lifting tray 812 to move downward back to the initial height.

[0042] In one implementation, the power assembly 83 includes: a support base 831, a track mechanism 832, two power roller assemblies 833, and an opening / closing mechanism 834; the support base 831 is provided with a mounting port 8311, through which the movement 82 passes; the track mechanism 832 is mounted on the support base 831; the power roller assemblies 833 can be arranged on opposite sides of the movement 82, and each power roller assembly 833 includes a sliding base 8331, power rollers 8332, and a drive motor 8333; the sliding base 8331 is slidably connected to the track mechanism 832, and the drive motor 8333 is mounted on the sliding base 8331. On 331, and connected to the power roller 8332; the opening and closing mechanism 834 includes a first synchronous belt 8341, first pulleys 8342 disposed at both ends of the first synchronous belt 8341, and a first motor 8343 capable of driving the first pulleys 8342. The first pulleys 8342 are rotatably connected to the support base 831. The sliding base 8331 of one power roller assembly 833 is connected to the upper side of the first synchronous belt 8341, and the sliding base 8331 of the other power roller assembly 833 is connected to the lower side of the first synchronous belt 8341. The first motor 8343 has torque feedback and automatic brake function.

[0043] With the above settings, firstly, the first motor 8343 can control the power roller 8332 to move closer to or further away from the core 82 without manual adjustment, making it convenient to connect the core 82 to the grid; secondly, when the power roller 8332 squeezes the core 82, the torque of the first motor 8343 increases, and when the torque reaches the preset value, the first motor 8343 can automatically engage the brake, so that the clamping force of the power roller 8332 on the core 82 is moderate; thirdly, the first motor 8343 can simultaneously drive the movement of two power roller assemblies 833.

[0044] Specifically, the support base 831 can be bolted into the harvester; the track mechanism 832 guides the sliding base 8331, ensuring that the two sliding bases 8331 can only move in a straight line; the power rollers 8332 of the two power roller assemblies 833 are parallel to each other, and the sliding direction of the sliding base 8331 of the power roller assembly 833 is perpendicular to the axis of the power roller 8332; when the mesh needs to be fed onto the machine core 82, the mesh sleeve is manually placed on the machine core 82, and the machine core 82 supports the inner wall of the mesh sleeve. At this time, the mesh sleeve is located between the machine core 82 and the power roller 8332, and the distance between the power rollers 8332 of the two power roller assemblies 833 and the machine core 82 is the same; the upper and lower sides of the first synchronous belt 8341 are parallel to the sliding direction of the sliding base 8331, and the first motor 8343 drives the first pulley. At time 8342, the upper and lower sides of the first synchronous belt 8341 move at equal speeds but in opposite directions. One power roller assembly 833 moves with the upper side of the first synchronous belt 8341, while the other power roller assembly 833 moves with the lower side of the first synchronous belt 8341 at the same speed. Eventually, the power rollers 8332 of both power roller assemblies 833 simultaneously contact the outer wall of the mesh sleeve and gradually clamp the mechanism 82. The clamping force gradually increases, and correspondingly, the torque of the first motor 8343 increases. When the torque of the first motor 8343 increases to a preset value, the first motor 8343 stops and automatically brakes, locking the clamping force. The first motor 8343 with automatic braking and torque feedback functions can be purchased commercially, while the preset value is set by those skilled in the art according to actual needs. The drive motor 8333 drives the power roller 8332 to rotate, thereby driving the mesh sleeve downwards.

[0045] In one implementation, the net-cutting assembly 84 includes: a base plate 841, a hot-melt wire 842, a first slider 843, a second synchronous belt 844, a second pulley 845, and a second motor 846; the base plate 841 is horizontally positioned above the fruit-supporting assembly 81; the hot-melt wire 842 can cut the net after being energized and heated; the first slider 843 is installed at both ends of the hot-melt wire 842 to tension the hot-melt wire 842, and the first slider 843 is slidably connected to the base plate 841; the second synchronous belt 844 is parallel to the direction of movement of the first slider 843; the second pulley 845 supports both ends of the second synchronous belt 844 and is rotatably connected to the base plate 841; the second motor 846 is installed on the base plate 841 and can drive the second pulley 845.

[0046] With the above configuration, the second motor 846 can drive the hot melt wire 842 to reciprocate through the second synchronous belt 844. When the hot melt wire 842 passes through the mesh sleeve, it can cut the mesh sleeve.

[0047] As one implementation, an integrated fruit and vegetable buffering, grading, and netting device also includes a counting mechanism 13; the counting mechanism 13 includes: a base 131, a drive roller 132, an encoder 133, a driven roller 134, and a clamping mechanism 135; the base is positioned above the mechanism, and the base 131 has a through hole 1311 through which the netting can pass; the drive roller 132 is rotatably connected to the base 131; the encoder 133 is mounted on the base 131 and can count the number of rotations of the drive roller 132; the driven roller 134 is parallel to the drive roller 132. The clamping mechanism 135 includes a mounting plate 1351, a second slider 1352, a fixing block 1353, and a spring 1354. The mounting plate 1351 is mounted on the base 131. The second slider 1352 is slidably connected to the mounting plate 1351. The end of the driven roller 134 is rotatably connected to the second slider 1352. The fixing block 1353 is fixedly connected to the mounting plate 1351. The spring 1354 is installed between the fixing block 1353 and the second slider 1352 so that the driven roller 134 presses the mesh sleeve onto the driving roller 132.

[0048] With the above settings, firstly, it facilitates internet access; secondly, the driving roller 132 and the driven roller 134 can stably clamp the mesh sleeve and prevent it from loosening; and thirdly, the encoder 133 is used for counting, resulting in high counting accuracy.

[0049] Specifically, the base 131 can be bolted onto the harvester; the through hole 1311 is square, and the drive roller 132 is located on the upper side of the base 131 and parallel to one side of the through hole 1311; the horizontal projection of the side of the drive roller 132 near the driven roller 134 is located within the horizontal projection of the through hole 1311, so that the net sleeve will not contact the hole wall of the through hole 1311 when it moves vertically downward between the drive roller 132 and the driven roller 134; the axis of the driven roller 134 is at the same height as the axis of the drive roller 132; one end of the spring 1354 is connected to the fixed block 1353, and the other end of the spring 1354 is connected to the slider. The spring 1354 is in a compressed state, and the spring 1354 pushes the driven roller 134 through the slider. The driven roller 134 and the drive roller 132 clamp the net sleeve. When the net sleeve moves downward, the drive roller 132 and the driven roller 134 rotate accordingly. Roller 132 and driven roller 134 provide a certain resistance to the mesh sleeve, keeping it taut. Encoder 133 can calculate the number of rotations of drive roller 132, and combined with the circumference of drive roller 132, the downward output length of the mesh sleeve can be calculated. When the downward output length of the mesh sleeve is close to the total length of the mesh sleeve, the mesh sleeve is put on. The operator manually pushes driven roller 134, moving it away from drive roller 132. Driven roller 134 and drive roller 132 separate, and the slider moves closer to fixed block 1353. Spring 1354 is compressed, and a new mesh sleeve passes downward between drive roller 132 and driven roller 134. After releasing the operator, spring 1354 automatically returns to its original position. Spring 1354 pushes driven roller 134 towards drive roller 132 through slider. Driven roller 134 and drive roller 132 clamp the mesh sleeve again. The mesh sleeve can be put on without disassembling the counting mechanism 13, making the mesh sleeve easy to install.

[0050] As one implementation, the buffer mechanism 4 includes: a frame 41, a turntable 42, a first drive mechanism 43, a fruit rack 44, and a flipping unit 45; the frame 41 is installed in the harvester; two turntables 42 are rotatably connected in the frame 41, and the two turntables 42 are arranged opposite to each other; the first drive mechanism 43 is installed on the frame 41 and can drive the turntables 42 to rotate; several fruit racks 44 are horizontally rotatably connected between the turntables 42, and the fruit racks 44 are provided with fruit troughs for placing fruits and vegetables. The fruit feeding mechanism 5 can guide the fruits and vegetables from the harvester into one of the fruit troughs, and under the action of gravity, the opening of the fruit trough faces upward; the flipping unit 45 is installed on the frame 41, and the flipping unit 45 can flip the fruit racks 44 so that the fruits and vegetables fall into the fruit delivery mechanism 6.

[0051] With the above settings, fruits and vegetables are less likely to be crushed when they are stored in the fruit rack 44.

[0052] Specifically, the output end of the fruit feeding mechanism 5 is close to one of the fruit racks 44. After the fruits and vegetables output by the fruit feeding mechanism 5 are introduced into the fruit trough, they are laid out in a single layer along the axis of the fruit rack 44, preventing them from being squeezed together and thus avoiding damage. When one of the fruit racks 44 is full, the first drive mechanism 43 drives the turntable 42 to rotate, bringing the other fruit rack 44 closer to the output end of the fruit feeding mechanism 5 to continue receiving fruits and vegetables from it. The buffer mechanism 4 operates similarly to a Ferris wheel; when the turntable 42 rotates, the opening of the fruit trough always faces upward. When the buffer mechanism 4 needs to output fruits and vegetables, the flipping part drives one of the fruit racks 44. After the fruit rack 44 rotates, the opening of the fruit trough tilts downward, causing the fruits and vegetables to fall into the fruit delivery mechanism 6, which then transports them to the netting mechanism 8. The flipping part can be a rotary cylinder or similar device, depending on the specific requirements.

[0053] In one implementation, the fruit racks 44 are arranged sequentially along the circumference of the turntable 42; the feeding mechanism 5 includes: a feeding cylinder 51, a feeding mechanism (not shown in the figure), and a second driving mechanism 53; the feeding cylinder 51 forms a receiving space 511 that can hold fruits and vegetables, and the upper side of the feeding cylinder 51 is provided with a fruit outlet 512 communicating with the receiving space 511, and the feeding cylinder 51 is arranged parallel to the inner side of the fruit rack 44; the feeding mechanism is installed on the frame 41, and the feeding mechanism can guide the fruits and vegetables of the harvester into the feeding cylinder 51 through the fruit outlet 512; the second driving mechanism 53 is installed on the frame 41, and the second driving mechanism 53 can drive the feeding cylinder 51 to rotate so that the fruits and vegetables in the feeding cylinder 51 can be poured into one of the fruit racks 44 through the fruit outlet 512.

[0054] In one implementation, a clearance hole 421 is provided at the center of one of the turntables 42, and one end of the feeding cylinder 51 passes through the clearance hole 421 to extend to the outside of the turntable 42; the receiving space 511 includes a receiving part 5111 located on the outside of the turntable 42, and a discharging part 5112 located between the two turntables 42; the feeding mechanism is located on the outside of the turntable 42 to deliver the fruits and vegetables output by the harvester into the receiving part 5111; the feeding mechanism 5 also includes: a push plate 54, a push rod 55 and a third drive mechanism 56; the push plate 54 is located inside the receiving part 5111; one end of the push rod 55 is connected to the push plate 54, and the other end of the push rod 55 faces away from the discharging part 5112 and extends to the outside of the feeding cylinder 51; the third drive mechanism 56 is mounted on the frame 41 and can drive the push plate 54 through the push rod 55 to push the fruits and vegetables in the receiving part 5111 into the discharging part 5112.

[0055] The above settings facilitate the feeding mechanism to transport fruits and vegetables from the outside to the inside of the buffer mechanism 4, and also facilitate the installation of the feeding mechanism.

[0056] In this application, the length of the fruit discharge section 5112 is basically the same as the length of the fruit rack 44. After the fruits and vegetables in the fruit discharge section 5112 are poured into the fruit rack 44, the entire fruit rack 44 can be filled, improving the utilization rate of the fruit rack 44. The feeding mechanism can be in the form of a conveyor belt or an auger roller, etc., to transport the fruits and vegetables picked by the harvester into the fruit receiving section 5111 of the feeding cylinder 51. The third drive mechanism 56 drives the push plate 54, and the push plate 54 pushes the fruits and vegetables into the fruit discharge section 5112. The fruit discharge section 5112 can be set on the upper side. A photoelectric sensor is used to calculate the number of fruits and vegetables entering the feeding cylinder 51. When the fruit outlet 5112 is basically full of fruits and vegetables, the second drive mechanism 53 drives the feeding cylinder 51 to rotate. The fruit outlet 512 of the feeding cylinder 51 faces downward, and the fruits and vegetables in the fruit outlet 5112 are poured onto the fruit rack 44 below. Then, the second drive mechanism 53 drives the feeding cylinder 51 to rotate in the opposite direction and reset. The first drive mechanism 43 drives the turntable 42 to rotate, so that another empty fruit rack 44 moves to the bottom of the feeding cylinder 51 to prepare for the next round of feeding.

[0057] As one implementation, the fruit feeding mechanism 5 also includes a stop block 57, which is installed in the fruit feeding cylinder 51 and positioned between the fruit receiving part 5111 and the fruit discharging part 5112. Fruits and vegetables can roll over the upper side of the stop block 57 into the fruit discharging part 5112 under the action of the push plate 54.

[0058] The above settings can prevent fruits and vegetables entering the fruit outlet section 5112 from rolling back into the fruit outlet section 5112.

[0059] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
