Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product transportation, in particular to a transportation device for wholesale of edible agricultural products. Background Art

[0002] Currently, transfer devices are widely used in the wholesale of edible agricultural products. However, most existing transfer devices can only accommodate the placement and handling of single-layer cargo, which presents significant limitations when handling agricultural products that cannot be stacked or compressed. When it comes to transporting both fragile, non-stackable agricultural and sideline products and standard, stackable agricultural and sideline products, existing transfer devices often struggle to accommodate both types of cargo, preventing effective classification and storage. This results in low transfer efficiency and can easily damage the agricultural products.

[0003] Existing transfer devices often rely on manual handling or simple mechanical structures for loading and unloading. This method is inefficient and can easily damage agricultural products during handling. Furthermore, existing transfer devices lack space utilization, failing to accommodate large quantities of non-stacking agricultural products and adapting to the diverse and sophisticated transport requirements of edible agricultural products. Therefore, a transfer device for wholesale edible agricultural products is needed to meet these needs. Summary of the Invention

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example: See Figure 1-7 The present invention provides a technical solution: a transfer device for wholesale edible agricultural products, comprising a base plate 1; a base column 6 is fixedly mounted on the base plate 1, an upper base plate 7 is fixedly mounted above the base column 6, a brake universal wheel 5 is provided at the bottom of the base plate 1, and the transfer device further comprises:

[0045] The carrier plate 10 has four rollers 11 mounted on the bottom thereof;

[0046] The loading and unloading device 2 is arranged on the bottom plate 1. The agricultural products are placed on the loading and unloading device 2 through the supporting plate 10. The loading and unloading device 2 pushes the supporting plate 10 to move to realize loading and unloading.

[0047] The multi-layer storage device 3 is arranged on the bottom plate 1. The multi-layer storage device 3 can drive the loading and unloading device 2 to move up and down. By utilizing the cooperation between the multi-layer storage device 3 and the loading and unloading device 2, multi-layer storage of goods can be achieved.

[0048] When in use, it is also necessary to set a switch button or a main controller with a control screen on the device. The switch button and the main controller can be set on one side of the base plate 1 to ensure that their position will not cause interference and influence. They can also be set on the side of the base column 6 away from the material platform 20, and the switch button or the main controller is electrically connected to the first motor 24 and the second motor 35. When using switch control, the same electrical device should be provided with two buttons for forward and reverse rotation, and the output rotation direction of the first motor 24 and the second motor 35 can be switched by changing the positive and negative conduction directions. Select the power supply mode according to the usage scenario: If the device needs to move over a large range, a mobile power supply can be set inside or on one side of the base plate 1, and the mobile power supply can be converted into AC power through an inverter and then connected to the AC device. When using the main controller for control, a relay should also be connected to the control circuit, and the main controller controls the start and stop of the electrical device through the relay; if the device does not need to move long distances, the relay or switch input can be directly connected to the mains power, and ensure that the connecting line has sufficient length to meet the needs of device movement. When setting up a mobile power supply, the power supply should be set on the side of the base plate 1 away from the material platform 20 as much as possible. If a mobile power supply is not set up, a counterweight block can be set on the side of the base plate 1 away from the material platform 20.

[0050] The loading and unloading device 2 also includes: a first motor 24, which is fixedly installed in the material table 20, and the output shaft of the first motor 24 is fixedly connected to the first transmission wheel 25 on one side of the storage groove 23; a transmission shaft 28, which is rotatably installed inside the material table 20 away from the end of the first motor 24, and the two ends of the transmission shaft 28 are respectively fixedly connected to the transmission wheels 25 on both sides of the storage groove 23; a through groove 29, which is opened at the end of the material table 20 close to the storage groove 23, and the through groove 29 is connected to the storage groove 23. The multi-layer storage device 3 includes: a first fixed plate 30, one end of the first fixed plate 30 is fixedly connected to the upper surface of the bottom plate 1, and the other end is fixedly connected to the lower surface of the upper base plate 7, and the first fixed plate 30 passes through the through-slot 29 and slides in the through-slot 29; a storage card strip 31, the storage card strip 31 is fixedly mounted on the side of the first fixed plate 30 away from the upper base plate 7, and the storage card strip 31 is slidably mounted in the storage slot 23; a second motor 35, the second motor 35 is fixedly mounted on the lower surface of the upper base plate 7, and is positioned On one side of the first fixed plate 30; a screw rod 36, one end of which is fixedly connected to the output shaft of the second motor 35, and the other end of which passes through the material table 20 and is rotatably installed in the bottom plate 1, and the screw rod 36 is threadedly engaged with the material table 20; a first slide rod 32, one end of which is fixedly connected to the upper surface of the bottom plate 1, and the other end of which is fixedly connected to the lower surface of the upper base plate 7, and the first slide rod 32 passes through the material table 20 and slides with the material table 20, and the first slide rod 32 and the screw rod 36 are symmetrically installed about the first fixed plate 30. The multi-layer storage device 3 also includes: a slot 33, which is opened on the upper surface of the storage card strip 31 and is located on the side of the storage card strip 31 away from the first fixed plate 30; and an insertion rod 34, which is inserted into the slot 33, and the insertion rod 34 and the slot 33 have an interference fit.

[0051] An extension block 9 is fixedly mounted on one end of the material platform 20 near the storage area 22. A shock-absorbing damper 4 is fixedly mounted on the upper surface of the base plate 1, located between the base plate 1 and the extension block 9. A second slide bar 8 is mounted between the base plate 1 and the upper base plate 7. The second slide bar 8 is fixedly connected to the base plate 1 and the upper base plate 7 at both ends. The second slide bar 8 passes through the extension block 9 and slides with the extension block 9, with a clearance fit between the second slide bar 8 and the extension block 9.

[0052] When in use, push the device to the side of the agricultural and sideline products that need to be transported, and lock the brake pads on the brake universal wheel 5. After packing the agricultural and sideline products, move them to the carrier plate 10, and place the carrier plate 10 on the material table 20 so that the carrier plate 10 is located in the storage area 22 and between the two levers 27. Start the second motor 35 through the main controller or button. Pay attention to the rotation direction of the second motor 35 when starting. At this time, the second motor 35 should be engaged with the material table 20 through the screw rod 36, and the screw rod 36 drives the material table 20 to rise. When the material table 20 rises and the top storage card strip 31 is stuck in the storage groove 23, the second motor 35 is stopped. At this time, the upper surface of the material table 20 is slightly higher than the upper surface of the storage card strip 31. Start the first motor 24 through the button or main controller. Pay attention to the rotation direction of the first motor 24 when starting. Direction of rotation: At this time, the first motor 24 should be rotated counterclockwise (with the output shaft of the first motor 24 as the reference direction). When the first motor 24 rotates, it will drive the transmission wheel 25 and the transmission belt 26 to rotate. The transmission wheel 25 on one side drives the transmission wheel 25 and the transmission belt 26 on the other side to rotate through the transmission shaft 28. When the transmission belt 26 rotates, the lever 27 will press against the carrier plate 10 and push the carrier plate 10 toward the side of the storage area 22. When the carrier plate 10 is pushed onto the storage area 22, the material platform 20 will stop. Start the second motor 35 again and reverse the rotation of the second motor 35, so that the second motor 35 engages with the material platform 20 through the screw rod 36, and the screw rod 36 drives the material platform 20 to descend. When the material platform 20 descends, the carrier plate 10 will rest on the storage card strip 31, and the material platform 20 will gradually separate from the carrier plate 10.

[0053] The material platform 20 is reset until it reaches the bottom of the screw rod 36, then the second motor 35 is stopped and the carrier plate 10 is moved onto the material platform 20 again. If there are two or more storage clips 31 on the first fixed plate 30, the above operation is repeated to move the carrier plate 10 to the storage clip 31 below the previous carrier plate 10. When it is necessary to store the carrier plate 10 on the bottom storage clip 31, there is no need to start the second motor 35 to raise or lower the material platform 20. The transmission wheel 25 can be directly driven to push the carrier plate 10 onto the storage clip 31. Alternatively, the transmission wheel 25 can be left unactivated and the last carrier plate 10 can be directly placed in the storage area 22 on the material platform 20.

[0054] After the carrier plate 10 is placed on the multi-layer storage device 3 , the insertion rod 34 needs to be inserted into the slot 33 to limit the carrier plate 10 and prevent it from rolling when the device is moved.

[0055] In order to ensure the reliability of operation, the first motor 24 and the second motor 35 should use reduction motors, and the rotation speed of the first motor 24 and the second motor 35 should be limited to a smaller speed range. The specific rotation speed should be adjusted according to the actual size of the device and the reaction force of the operator, but in general, the slower the rotation speed, the easier it is to control the position of the carrier plate 10 when using the button to manually control the start and stop of the motor. When using the main controller for control, the motor can be controlled in a closed loop, and the rotation direction and number of revolutions of the motor can be accurately calculated and set to achieve precise closed-loop control.

[0056] When moving the device, unlock the brake pads on the brake universal wheel 5, push the device to the unloading position, and unload the materials one by one from bottom to top. First, remove the plug rod 34, and use the second motor 35 to drive the screw rod 36 to rotate, so that the material platform 20 is located below the carrier plate 10 placed on the lowest storage card strip 31. At the same time, the upper surface of the material platform 20 is slightly higher than the upper surface of the lowest storage card strip 31, and ensure that the carrier plate 10 is located between the two levers 27. At this time, the lower surface of the carrier plate 10 is separated from the upper surface of the storage card strip 31, and the roller 11 is in contact with the upper surface of the material platform 20. Reverse the first motor 24 and let the first motor 24 rotate clockwise (with the motor output shaft as the reference direction). At this time, the lever 27 will push the carrier plate 10 to move to the storage area 22 on the material platform 20, and then manual unloading is required. Repeat the above operation, use the second motor 35 to use the screw rod 36 to drive the material platform 20 to rise to the bottom of the supporting plate 10 of the upper layer of storage card strip 31 and then stop. In the same way as the above method, let the first motor 24 output rotation clockwise to push the supporting plate 10 to the storage area 22 of the material platform 20, and then let the material platform 20 descend. Repeat this process to ensure that the loading is from top to bottom and the unloading is from bottom to top one by one.

[0057] In order to ensure safety during unloading, a rod or other structure may be provided on the side of the material platform 20 away from the storage area 22 for limiting the position. The angle of the slope on this side may also be increased when designing the material platform 20.

[0058] It is worth noting that, to facilitate the positioning of the carrier plate 10 between the two levers 27 during blanking, the spacing between the two levers 27 can be significantly greater than the width of the carrier plate 10, rather than being slightly greater than the width of the carrier plate 10 as shown in the accompanying drawings. The distance between the levers 27 can be freely set, but should not be less than or equal to the width of the carrier plate 10. The smaller the distance between the levers 27, the more difficult it is to position the carrier plate 10 between the two levers 27 during blanking.

[0059] This device is particularly suitable for transporting agricultural products that cannot be stacked or pressed. If it is necessary to transport fragile agricultural and sideline products that cannot be stacked and ordinary stackable agricultural and sideline products at the same time, in order to improve the transportation efficiency, the fragile agricultural and sideline products can be stored on the storage card strip 31, and the stackable ones can be placed on the material table 20 for stacking.

[0060] If the operating environment of the device is relatively harsh, a screw dust cover can be installed on the screw 36 above and below the material platform 20, and one end of the screw dust cover above the material platform 20 is fixed to the end face of the second motor 35, and the other end is fixed to the upper surface of the material platform 20, and one end of the screw dust cover below the material platform 20 is fixed to the base plate 1, and the other end is fixed to the lower surface of the material platform 20. The screw dust cover is an existing product, which is a stretchable and contractible hollow sleeve with a shape similar to a steel wire telescopic hose.

[0061] The storage card strip 31 is fixedly connected to the first fixed plate 30, and the fixing method can be welding, or a fixing plate can be welded on the storage card strip 31 and then connected using fasteners such as bolts. The distance between the upper and lower storage card strips 31 can be freely set according to the height of the goods to be transported, but the distance between the upper and lower storage card strips 31 cannot be less than the thickness of the material table 20. When the storage card strip 31 is connected to the first fixed plate 30 by fasteners, such as bolts, multiple fixing holes can be opened linearly along the height direction of the first fixed plate 30. When in use, the fixed position of the storage card strip 31 can be freely set according to the actual height of the goods, thereby expanding the applicability of the device.

[0062] The working principle is: when in use, it is also necessary to set a switch button or a main controller with a control screen on the device, and electrically connect the switch button or main controller to the first motor 24 and the second motor 35. When using switch control, the same electrical device should be provided with two buttons for forward and reverse rotation, and the output rotation direction of the first motor 24 and the second motor 35 can be switched by changing the positive and negative pole conduction directions. Select the power supply mode according to the usage scenario: if the device needs to be moved over a large range, a mobile power supply can be set inside or on one side of the base plate 1, and the mobile power supply can be converted into AC power through an inverter and then connected to the AC device. When using the main controller for control, a relay should also be connected to the control circuit, and the main controller controls the start and stop of the electrical device through the relay; if the device does not need to be moved over a long distance, the relay or switch input can be directly connected to the mains power, and ensure that the connecting line is of sufficient length to meet the needs of device movement.

[0063] When in use, push the device to the side of the agricultural and sideline products that need to be transported, and lock the brake pads on the brake universal wheel 5. After packing the agricultural and sideline products, move them to the carrier plate 10, and place the carrier plate 10 on the material table 20 so that the carrier plate 10 is located in the storage area 22 and between the two levers 27. Start the second motor 35 through the main controller or button. Pay attention to the rotation direction of the second motor 35 when starting. At this time, the second motor 35 should be engaged with the material table 20 through the screw rod 36, and the screw rod 36 drives the material table 20 to rise. When the material table 20 rises and the top storage card strip 31 is stuck in the storage groove 23, the second motor 35 is stopped. At this time, the upper surface of the material table 20 is slightly higher than the upper surface of the storage card strip 31. Start the first motor 24 through the button or main controller. Pay attention to the rotation direction of the first motor 24 when starting. Direction of rotation: At this time, the first motor 24 should be rotated counterclockwise (with the output shaft of the first motor 24 as the reference direction). When the first motor 24 rotates, it will drive the transmission wheel 25 and the transmission belt 26 to rotate. The transmission wheel 25 on one side drives the transmission wheel 25 and the transmission belt 26 on the other side to rotate through the transmission shaft 28. When the transmission belt 26 rotates, the lever 27 will press against the carrier plate 10 and push the carrier plate 10 toward the side of the storage area 22. When the carrier plate 10 is pushed onto the storage area 22, the material platform 20 will stop. Start the second motor 35 again and reverse the rotation of the second motor 35, so that the second motor 35 engages with the material platform 20 through the screw rod 36, and the screw rod 36 drives the material platform 20 to descend. When the material platform 20 descends, the carrier plate 10 will rest on the storage card strip 31, and the material platform 20 will gradually separate from the carrier plate 10.

[0064] The material platform 20 is reset until it reaches the bottom of the screw rod 36, then the second motor 35 is stopped and the carrier plate 10 is moved onto the material platform 20 again. If there are two or more storage clips 31 on the first fixed plate 30, the above operation is repeated to move the carrier plate 10 to the storage clip 31 below the previous carrier plate 10. When it is necessary to store the carrier plate 10 on the bottom storage clip 31, there is no need to start the second motor 35 to raise or lower the material platform 20. The transmission wheel 25 can be directly driven to push the carrier plate 10 onto the storage clip 31. Alternatively, the transmission wheel 25 can be left unactivated and the last carrier plate 10 can be directly placed in the storage area 22 on the material platform 20.

[0065] After the carrying plate 10 is placed on the multi-layer storage device 3 , the insertion rod 34 needs to be inserted into the slot 33 to limit the carrying plate 10 and prevent it from rolling when the device is moved.

[0066] In order to ensure the reliability of operation, the first motor 24 and the second motor 35 should use reduction motors, and the rotation speed of the first motor 24 and the second motor 35 should be limited to a smaller speed range. The specific rotation speed should be adjusted according to the actual size of the device and the reaction force of the operator, but in general, the slower the rotation speed, the easier it is to control the position of the carrier plate 10 when using the button to manually control the start and stop of the motor. When using the main controller for control, the motor can be controlled in a closed loop, and the rotation direction and number of revolutions of the motor can be accurately calculated and set to achieve precise closed-loop control.

[0067] When moving the device, unlock the brake pads on the brake universal wheel 5, push the device to the unloading position, and unload the materials one by one from bottom to top. First, remove the plug rod 34, and use the second motor 35 to drive the screw rod 36 to rotate, so that the material platform 20 is located below the carrier plate 10 placed on the lowest storage card strip 31. At the same time, the upper surface of the material platform 20 is slightly higher than the upper surface of the lowest storage card strip 31, and ensure that the carrier plate 10 is located between the two levers 27. At this time, the lower surface of the carrier plate 10 is separated from the upper surface of the storage card strip 31, and the roller 11 is in contact with the upper surface of the material platform 20. Reverse the first motor 24 and let the first motor 24 rotate clockwise (with the motor output shaft as the reference direction). At this time, the lever 27 will push the carrier plate 10 to move to the storage area 22 on the material platform 20, and then manual unloading is required. Repeat the above operation, use the second motor 35 to use the screw rod 36 to drive the material platform 20 to rise to the bottom of the supporting plate 10 of the upper layer of storage card strip 31 and then stop. In the same way as the above method, let the first motor 24 output rotation clockwise to push the supporting plate 10 to the storage area 22 of the material platform 20, and then let the material platform 20 descend. Repeat this process to ensure that the loading is from top to bottom and the unloading is from bottom to top one by one.
