Description

Technical Field

[0001] The utility model relates to the technical field of sweet potato sorting, in particular to a mobile sweet potato sorting machine in the field. Background Technique

[0002] Sweet potatoes are common native crops. With the gradual improvement of the requirements for sweet potato quality, during sweet potato processing, it is usually necessary to sort sweet potatoes of different sizes. In order to effectively improve the working efficiency of sweet potato sorting, corresponding automatic sorting machines are mostly used.

[0003] For example, a plate-type fruit and vegetable sorting precision-adjustable fruit and vegetable sorting system with the publication number of CN117463598A includes a chain power unit, which includes a ring-shaped chain that can rotate; a plurality of guide plates, the guide plates are provided with a connecting shaft and a lower rolling body, and the connecting shaft is rotatably connected to the ring-shaped chain; a first guide rail, the lower rolling body of the guide plate located at the upper part of the fruit and vegetable sorting system abuts against the upper surface of the first guide rail, and the upper surface of the first guide rail is inclined to the horizontal plane.

[0004] Among the above-mentioned existing technologies, the following technical problems exist: when the existing sorting machine sorts fruits and vegetables, different sizes of fruits and vegetables are sorted by changing the inclination angle of the guide plate. However, in the actual sorting process, the guide plate can only transfer the fruits and vegetables, but cannot turn the fruits and vegetables during the transfer process. Since fruits and vegetables are usually irregular in shape, and irregularly shaped fruits and vegetables are prone to getting stuck between adjacent guide plates during transfer, resulting in inability to fall downward for sorting, thereby reducing the sorting effect of fruits and vegetables.

[0005] Therefore, we propose a mobile sweet potato sorting machine in the field to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a mobile sweet potato sorting machine in the field to solve the problem that in the current market, when the existing sorting machine sorts fruits and vegetables, different sizes of fruits and vegetables are sorted by changing the inclination angle of the guide plate. However, in the actual sorting process, the guide plate can only transfer the fruits and vegetables, but cannot turn the fruits and vegetables during the transfer process. Since fruits and vegetables are usually irregular in shape, and irregularly shaped fruits and vegetables are prone to getting stuck between adjacent guide plates during transfer, resulting in inability to fall downward for sorting, thereby reducing the sorting effect of fruits and vegetables.

[0007] To achieve the above purpose, the utility model provides the following technical scheme: a mobile sweet potato sorting machine in the field, including a tractor, a baffle conveyor belt is installed on the side of the tractor, a buffer belt is arranged at one end of the baffle conveyor belt close to the tractor, and the tractor is used to provide the moving walking power of the sorting machine, so that the sorting machine can move in the field;

[0008] It also includes:

[0009] A fruit picking conveyor is installed at the right end of the buffer belt, and first manual workstations are arranged on both the front and back sides of the fruit picking conveyor. An adjustable sorting machine is installed at the right end of the fruit picking conveyor, and second manual workstations are installed at both the front and back ends of the adjustable sorting machine.

[0010] Preferably, the adjustable sorting machine includes a frame. Two guardrails are fixedly installed on the frame, and a transmission chain is installed inside the frame. The transmission chain is driven to rotate by a sprocket, and the sprocket is fixed on the output shaft of a driving motor. A fixing block is fixedly connected to the upper end of the transmission chain, and a guiding roller is installed on the fixing block. The guiding roller is installed through a sorting plate. A guiding wheel is fixedly connected to the end of the central rotating shaft of the guiding roller. A resisting rod is fixedly connected to the side of the sorting plate. An adapter plate and an adjusting frame are fixedly connected to the inner side of the frame, and the adapter plate is located above the adjusting frame. A belt conveyor is arranged below the transmission chain, and a collecting basket is arranged below the end of the belt conveyor. The belt conveyor is used to convey the sorted sweet potatoes into the collecting basket. A vibrating component is installed inside the sorting plate, and the vibrating component is used to increase the falling speed of the sweet potatoes between adjacent sorting plates.

[0011] Preferably, a plurality of fixing blocks are evenly distributed on the transmission chain, and a guiding roller is rotatably connected to each fixing block, and the guiding roller and the sorting plate are rotatably connected.

[0012] By adopting the above technical solution, when the transmission chain is driven to rotate by the sprocket, the guiding roller can be driven to move synchronously through the fixing block.

[0013] Preferably, the circumferential surface of the guiding wheel is set as a rough surface, and the guiding wheel can rotate after contacting the adapter plate when moving along with the guiding roller.

[0014] By adopting the above technical solution, the contact friction force with the adapter plate can be increased through the rough surface of the guiding roller, and then the guiding roller can be driven to rotate synchronously by the rotation of the guiding roller.

[0015] Preferably, the end of the resisting rod away from the sorting plate is set as a spherical structure, and the contact surface between the adjusting frame and the spherical end of the resisting rod is set as an inclined surface.

[0016] By adopting the above technical solution, through the movement of the spherical end of the resisting rod along the inclined surface of the adjusting frame, the inclination angle of the sorting plate can be changed accordingly, and then the distance between adjacent sorting plates can be changed.

[0017] Preferably, the vibrating component includes a double-headed cylinder, a first magnetic block, a second magnetic block, a striking rod and an auxiliary spring;

[0018] The double-headed cylinder is fixed inside the sorting plate, and a first magnet block is fixedly connected to the telescopic end of the double-headed cylinder. A second magnet block is arranged on the side of the first magnet block, and a striking rod is fixedly connected to the second magnet block. The second magnet block is interconnected with the inside of the sorting plate through an auxiliary spring.

[0019] By adopting the above technical solution, the arrangement of the auxiliary spring enables the striking rod and the second magnet block to reset and rebound after moving inside the sorting plate.

[0020] Preferably, the first magnet block and the second magnet block are on the same straight line, and the magnetic properties of the first magnet block and the second magnet block are opposite.

[0021] By adopting the above technical solution, when the first magnet block moves and the second magnet block approaches, the magnetic attraction can be used to make the second magnet block and the striking rod move synchronously.

[0022] Preferably, a plurality of striking rods are evenly distributed at equal intervals on the side of the second magnet block. The end of the striking rod away from the second magnet block is in contact with the inner side of the sorting plate in the initial state, and the striking rod is slidably connected to the inside of the sorting plate.

[0023] By adopting the above technical solution, the second magnet block drives the striking rod to move reciprocally, so as to facilitate the use of the striking rod to impact the sorting plate.

[0024] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this mobile sweet potato sorting machine in the field, it is convenient to turn the sweet potatoes during transmission, improving the screening effect of the sweet potatoes. At the same time, during sorting, the vibration generated by knocking prevents the sorted sweet potatoes from getting stuck between adjacent material separation plates.

[0025] 1. A baffle conveyor belt is provided. Through the arrangement of the baffle conveyor belt, it is convenient to transfer the sweet potatoes onto the fruit selection conveyor. Through the first manual positions on the front and back sides of the fruit selection conveyor, it is convenient for workers to pick out the sweet potatoes with worms or defects on the fruit selection conveyor. The selected sweet potatoes are continuously conveyed to the adjustable sorting machine to sort sweet potatoes of different diameters. Through the second manual positions on the front and back sides of the adjustable sorting machine, when problems such as sorting jams occur in the adjustable sorting machine, manual intervention operations can be carried out, integrating the sweet potato conveying and sorting into one machine, thus effectively improving the processing efficiency of sweet potatoes.

[0026] 2. Guide wheels are provided. When the drive chain rotates and drives the guide roller to move through the fixed block, after the guide roller moves, the contact between the guide wheel and the surface of the connecting plate enables the guide wheel to drive the guide roller to rotate during the moving process, thereby improving the turning ability of the sweet potatoes to facilitate better subsequent feeding of the sweet potatoes.

[0027] 3. An adjusting frame is provided. By the contact between the spherical end of the contact rod on the side of the sorting plate and the inclined surface of the adjusting frame, the sorting plate can be rotated and adjusted. Affected by the slope of the inclined surface of the adjusting frame, the rotation angle of the sorting plate will also change during the movement. With the change of the rotation angle of the sorting plate, the distance between its adjacent parts also changes accordingly. Thus, the sweet potatoes smaller than the distance between adjacent sorting plates will fall onto the lower belt conveyor and then enter the corresponding collection basket.

[0028] 4. A striking rod is provided. The double-headed cylinder is used to control the first magnet to move telescopically. Thus, by the change in the distance between the first magnet and the second magnet, the second magnet drives the striking rod to move back and forth. By using the vibration generated by the back-and-forth movement of the striking rod hitting the sorting plate, the sweet potatoes can be prevented from getting stuck between adjacent sorting plates, and the falling speed of the sweet potatoes between adjacent sorting plates can be increased.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] Embodiment 1: Please refer to Figures 1 - 7 , when the existing sorting machine sorts fruits and vegetables, different sizes of fruits and vegetables are sorted by changing the inclination angle of the guide plate. However, in the actual sorting process, the guide plate can only transfer the fruits and vegetables, but cannot turn them during the transfer. Since fruits and vegetables are usually irregular in shape, and irregularly shaped fruits and vegetables are likely to get stuck between adjacent guide plates during transfer, resulting in inability to fall down for sorting, thereby reducing the sorting effect of fruits and vegetables. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0039] Field mobile sweet potato sorter, including a tractor 1, a baffle conveyor belt 2 is installed on the side of the tractor 1, and a buffer belt 3 is arranged at one end of the baffle conveyor belt 2 close to the tractor 1; the tractor 1 is used to provide the moving walking power for the sorter, so that the sorter can move in the field. A fruit picking conveyor 4 is installed at the right end of the buffer belt 3, and a first manual position 5 is arranged on both the front and back sides of the fruit picking conveyor 4. An adjustable sorter 6 is installed at the right end of the fruit picking conveyor 4, and a second manual position 7 is installed at both the front and back ends of the adjustable sorter 6. The adjustable sorter 6 includes a frame 601, two guardrails 602 are fixedly installed on the frame 601, and a transmission chain 603 is installed inside the frame 601. The transmission chain 603 is driven to rotate by a sprocket, and the sprocket is fixed on the output shaft of the driving motor; a fixing block 604 is fixedly connected to the upper end of the transmission chain 603, and a guide roller 605 is installed on the fixing block 604. The guide roller 605 is installed through the sorting plate 606; a guide wheel 607 is fixedly connected to the end of the central rotating shaft of the guide roller 605, and a contact rod 608 is fixedly connected to the side of the sorting plate 606. An adapter plate 609 and an adjusting frame 610 are fixedly connected to the inner side of the frame 601, and the adapter plate 609 is located above the adjusting frame 610; a belt conveyor 611 is arranged below the transmission chain 603, and a collection basket 612 is arranged below the end of the belt conveyor 611. The belt conveyor 611 is used to convey the sorted sweet potatoes into the collection basket 612; a plurality of fixing blocks 604 are evenly distributed on the transmission chain 603, and a guide roller 605 is rotatably connected to each fixing block 604, and the guide roller 605 and the sorting plate 606 are rotatably connected. The circumferential surface of the guide wheel 607 is set as a rough surface, and the guide wheel 607 can rotate after contacting the adapter plate 609 when moving along with the guide roller 605. One end of the contact rod 608 away from the sorting plate 606 is set as a spherical structure, and the contact surface between the adjusting frame 610 and the spherical end of the contact rod 608 is set as an inclined surface.

[0040] When sorting sweet potatoes, the tractor 1 provides the whole device with walking power so that the sorting machine can move in the field. Then the sweet potatoes to be sorted are placed on the baffle conveyor belt 2, and the baffle conveyor belt 2 conveys the sweet potatoes to the fruit picking conveyor 4 through the buffer belt 3. At this time, the staff at the first manual position 5 picks out the borers or damaged sweet potatoes on the fruit picking conveyor 4. After the sweet potatoes are preliminarily processed, the sweet potatoes are continuously conveyed to the adjustable sorting machine 6, and the sprocket is controlled by the driving motor to rotate. The transmission chain 603 is rotated by the rotation of the sprocket, and then the sweet potatoes to be sorted are transported to the guide rollers 605 between the transmission chains 603 through the conveyor. When the transmission chain 603 rotates, it can drive the guide rollers 605 to move synchronously through the fixed block 604. The movement of the guide rollers 605 can be used to transfer the sweet potatoes. During the transfer process, the sweet potatoes fall downward through the gaps between the adjacent sorting plates 606 onto the belt conveyor 611, and are guided into the conveyor belt 611 through the transmission of the belt conveyor 611. The guide roller 605 moves to the inside of the collecting basket 612, and after the guide wheel 607 on the guide roller 605 contacts the connecting plate 609 after moving, the guide wheel 607 can drive the guide roller 605 to rotate on the sorting plate 606. The self-rotation of the guide roller 605 during the movement improves the turning effect of the sweet potatoes, which is more conducive to the falling of the sweet potatoes. When the sorting plate 606 moves with the guide roller 605, the spherical end of the resistance rod 608 on the side of the sorting plate 606 contacts the inclined surface of the adjusting frame 610. At this time, the inclined surface of the adjusting frame 610 The surface can interfere with the interference rod 608, causing the interference rod 608 and the sorting plate 606 to rotate. At the same time, due to the influence of the inclination slope of the adjustment frame 610, the rotation angle of the sorting plate 606 also changes. After the sorting plate 606 rotates, the distance between adjacent sorting plates 606 also changes. At this time, during the transportation of sweet potatoes, those smaller than the distance between adjacent sorting plates 606 fall onto the belt conveyor 611 and then enter the corresponding collection basket 612, thereby realizing automatic sorting of the sweet potatoes.

[0041] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. By installing a vibration component inside the sorting plate 606, the vibration generated by the vibration component hitting the sorting plate 606 is used to accelerate the falling rate of the sweet potatoes between adjacent sorting plates 606. Figures 1 - 7 As shown;

[0042] A vibration component is installed inside the sorting plate 606, and the vibration component is used to increase the falling rate of sweet potatoes between adjacent sorting plates 606. The vibration component includes a double-headed cylinder 613, a first magnet 614, a second magnet 615, a striking rod 616, and an auxiliary spring 617. The double-headed cylinder 613 is fixed inside the sorting plate 606, and the telescopic end of the double-headed cylinder 613 is fixedly connected to the first magnet 614. A second magnet 615 is arranged on the side of the first magnet 614, and a striking rod 616 is fixedly connected to the second magnet 615. The second magnet 615 is connected to the inside of the sorting plate 606 through the auxiliary spring 617. The first magnet 614 and the second magnet 615 are located on the same straight line, and the magnetic properties of the first magnet 614 and the second magnet 615 are opposite. A plurality of striking rods 616 are evenly distributed at equal intervals on the side of the second magnet 615. The end of the striking rod 616 away from the second magnet 615 is in contact with the inner side of the sorting plate 606 in the initial state, and the striking rod 616 and the inside of the sorting plate 606 are slidably connected.

[0043] During the process of sorting sweet potatoes, the double-headed cylinder 613 is turned on. The opening of the double-headed cylinder 613 enables the first magnet 614 to move telescopically. When the first magnet 614 moves closer to the second magnet 615, the magnetic attraction between the two enables the second magnet 615 to drive the striking rod 616 to move towards the center of the sorting plate 606. When the first magnet 614 moves away from the second magnet 615 after moving, the second magnet 615 and the striking rod 616 rebound under the action of the auxiliary spring 617. The sorting plate 606 is struck by the reset striking rod 616, and the vibration generated by the striking rod 616 hitting the sorting plate 606 is utilized to accelerate the falling speed of sweet potatoes between adjacent sorting plates 606.

[0044] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
