Description

Technical Field

[0001] The present invention relates to the field of article conveying, and in particular to an article conveying device. Background Art

[0002] At present, after express delivery, mail and other items arrive at the express delivery station, couriers are required to sort these express deliveries and mails from the ground to the shelves. Therefore, couriers need to bend down repeatedly to pick up each item from the ground and place them high on the shelves one by one. In this way, couriers need to bend down repeatedly, and the work intensity of courier workers is high, which brings great physical burden to the workers.

[0003] Although there are devices for conveying articles in the prior art, the article conveying device includes an electric conveying unit, and the electric conveying unit includes a conveyor belt. The courier places the articles on the ground on the conveyor belt, and the conveyor belt transfers the articles to a high place. However, when the articles reach the top of the conveyor belt, they will fall because there is no platform for storage, and the articles will fall back to the ground.

[0004] Even if a platform is set at the top of the conveyor belt to receive items, when a large number of items are conveyed up, the items subsequently conveyed to the platform will push the items on the platform forward, causing the items to fall to the ground.

[0005] Therefore, for a long time, when express delivery stations were sorting and putting express deliveries on the shelves, they did not use item conveying devices to load the goods, but still did it manually. Summary of the invention

[0006] The present invention is intended to provide an article conveying device to solve the current problem that the article conveying device cannot be used for loading goods because the articles fall off when being conveyed to the top of the conveyor belt.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an article conveying device, including an electric conveying unit, a placing table is provided at the top of the electric conveying unit, and a storage bag is connected to the end of the placing table away from the electric conveying unit; a stabilizing rod is connected to the electric conveying unit, and the end of the stabilizing rod away from the electric conveying unit acts on the placing table, and the number of stabilizing rods is at least two and they are respectively located on the left and right sides of the placing table; the stabilizing rods on the left and right sides of the placing table are inclined, and one end of the stabilizing rod connected to the electric conveying unit is the high end, and the other end is the low end.

[0008] The principle and advantages of this solution are as follows: The electric transmission unit is used to convey items upward. The express delivery personnel place multiple items underground on the electric transmission unit one by one. The electric transmission unit conveys the items from the bottom to the top direction and conveys multiple items upward to the placement table. Then the express delivery personnel stand up and place the items on the placement table on the shelf. In this way, the express delivery personnel do not need to repeatedly bend down to pick up the items on the ground one by one and place them on the shelf, which reduces the burden on the waist and lowers the labor intensity.

[0009] By setting up the placement table in this device, after the items are conveyed upward to the top of the device, the placement table can temporarily store the items. When a batch of items are conveyed to the placement table, the express delivery personnel stand up again and transfer the items on the placement table to a high position on the shelf, thus avoiding the problem that the items fall to the ground again without a placement table to store them after being conveyed to the top of the electric transmission unit.

[0010] When there are more items conveyed to the placement table, the items on the placement table can be pushed by the items conveyed subsequently into the storage bag for storage, avoiding the situation that the items on the placement table are pushed and fall to the ground due to being too many. Therefore, the setting of the storage bag can increase the storage quantity of the items at the top of the electric transmission unit.

[0011] In this solution, during use, one end of the stabilizing rod away from the electric transmission unit acts on the placement table. The stabilizing rod provides a force to the placement table, making the placement table in a stable horizontal placement state. At the same time, since the stabilizing rods are located on the left and right sides of the placement table, and the stabilizing rods on the left and right sides of the placement table are inclined, and the end of the stabilizing rod connected to the electric transmission unit is the high end and the other end is the low end, the stabilizing rods on the left and right sides of the placement table play a role in blocking the items, reducing the situation of the items falling from the left and right sides of the placement table, which is beneficial to ensuring that the items on the placement table are pushed by the items conveyed subsequently and slide forward into the storage bag, increasing the probability that the items pushed forward on the placement table enter the storage bag.

[0012] Preferably, as an improvement, the top of the electric transmission unit is rotatably connected to the placement table, and the stabilizing rod is detachably connected to the placement table; after the stabilizing rod and the placement table are disconnected, the placement table can be rotated to a state where it is attached to the electric transmission unit.

[0013] Thus, during the use of this device, the stabilizing rod and the placement table are connected. One end of the stabilizing rod away from the electric transmission unit acts on the placement table. The stabilizing rod provides a force to the placement table, making the placement table in a stable horizontal placement state. When this device is not in use, the placement table and the stabilizing rod are disconnected. The stabilizing rod no longer acts on the placement table, and the placement table is no longer restricted by the stabilizing rod. Then the placement table is rotated to make the placement table attached to the electric transmission unit, realizing the storage of the placement table and reducing the space occupied by the placement table.

[0014] Preferably, as an improvement, the electric conveying unit includes two conveying frames and a conveyor belt located between the two conveying frames. The two conveying frames support the conveyor belt, and the conveyor belt moves between the two conveying frames.

[0015] Preferably, as an improvement, the stabilizing rod is rotatably connected to the conveying frame. Thus, by rotating the stabilizing rod, the stabilizing rod can be rotated onto the placing table and connected to the placing table, and the stabilizing rod provides support for the placing table. When the placing table does not require the support of the stabilizing rod, the stabilizing rod can be rotated to the side of the conveying frame.

[0016] Preferably, as an improvement, the stabilizing rod and the placing table are detachably connected by a pin, detachably connected by a screw, or detachably connected by a hooking method.

[0017] Preferably, as an improvement, a first connecting portion is provided on the placing table, and a second connecting portion is provided on the electric conveying unit; when the placing table rotates to a state where it is in contact with the electric conveying unit, the first connecting portion and the second connecting portion are connected.

[0018] Thus, when the device is not needed, the stabilizing rod and the placing table are separated, and at the same time, the placing table is rotated so that the placing table rotates below the electric conveying unit and the placing table is in contact with the electric conveying unit, realizing the storage of the placing table. Then, through the connection of the first connecting portion and the second connecting portion, the placing table is restricted by the connection of the first connecting portion and the second connecting portion and will not rotate automatically, improving the stability after the placing table is stored, and the placing table is in a stable state of being in contact with the electric conveying unit.

[0019] Preferably, as an improvement, the first connecting portion is a clamping shaft, and the second connecting portion is a hook. A hook is rotatably mounted on the conveying frame by a shaft, and the clamping shaft is hooked by the hook, thereby realizing the fixation of the placing table, and the placing table can be in a stable state of being in contact with the electric conveying unit.

[0020] Preferably, as an improvement, the storage bag is detachably connected to the placing table. The storage bag is detachably connected to the placing table, and the storage bag can be detached from the placing table. When the placing table is stored, the storage bag can be removed from the placing table, and the storage bag will not affect the storage of the placing table. When the placing table is in use, the storage bag is reinstalled on the placing table.

[0021] Preferably, as an improvement, the storage bag is a foldable storage bag. When not in use, the foldable storage bag is easy to fold, thereby reducing space occupation.

[0022] Preferably, as an improvement, a bag cavity is provided on the placement table, and the storage bag is slidably arranged in the bag cavity. Thus, when the placement table is not in use, the storage bag is folded and slid into the bag cavity, thereby realizing the storage of the storage bag. The storage bag will not be randomly placed, avoiding the loss of the storage bag. When the storage bag is needed, it can be slid out of the bag cavity.

[0023] Preferably, as an improvement, the storage bag includes a soft folding part and two hard board parts. The soft folding part is connected between the two hard board parts, and the soft folding part and the two hard board parts enclose a storage cavity for storing items. Thus, the soft folding part has a certain flexibility and can be folded and unfolded. When the storage bag needs to be folded, the two hard board parts are moved closer to each other, and the soft folding part is compressed between the two hard board parts, thereby realizing the folding of the storage bag. When the storage bag is needed, the two hard board parts are moved away from each other, the soft folding part unfolds, the storage cavity is opened, and the storage bag can be used.

[0024] Preferably, as an improvement, the placement table includes a housing and a sliding plate. An opening communicating with the bag cavity is provided at one end of the housing away from the electric transmission unit, and the hard board part near the bottom of the housing is rotatably connected to the sliding plate; a limiting groove is provided on the inner wall of the bag cavity, and a limiting block is fixedly provided on the sliding plate, and the limiting block is slidably arranged in the limiting groove. Thus, after the storage bag is folded, it is pushed into the bag cavity, and the sliding plate moves to one end of the placement table close to the electric transmission unit, and the bottom of the storage bag seals the opening. When the storage bag needs to be taken out, the bottom of the storage bag is pulled outwards, the storage bag slides out of the bag cavity, the sliding plate slides to the opening of the bag cavity, and then the storage bag is rotated to make the storage bag in a vertical placement state and the storage bag is opened, so that items can be received. When the sliding plate slides to the opening of the bag cavity, the end of the limiting groove abuts against the limiting block, thereby being able to limit the sliding plate and prevent the sliding plate from disengaging from the opening. When the placement table is not in use, the storage bag is folded, and the storage bag is flipped to make the storage bag rotate to a state substantially in the same plane as the placement table, and then the storage bag and the sliding plate are pushed into the bag cavity again. Through this solution, whether the storage bag is used or not, the storage bag does not need to be separated from the placement table and is always in a state of being connected to the placement table, avoiding the loss of the storage bag, and the storage bag can be stored in the placement table, and the storage bag will not affect the storage of the placement table.

[0037] The following is a further detailed description through specific implementation manners: The reference numerals in the accompanying drawings of the specification include: conveying frame 1, conveyor belt 2, anti-slip strip 3, pull rod 4, storage bag 5, placing table 6, stabilizing rod 7, second support leg 8, friction pad 9, freight car 10, first support leg 11, third support leg 13, hook 14, card shaft 15, second connection block 16, first connection block 17, handle 18, fixed shaft 20, pin 21, card end 22, receiving groove 23, compression spring 24, conveying roller 25, second hard board 26, flexible folding part 27, first hard board 28, sliding plate 29, housing 30, limiting block 31, limiting groove 32, flexible block 33, pull rope 34, bag cavity 35, notch 36.

[0038] Example 1 Basically as shown in the appendix Figures 1 - 6As shown: The article conveying device includes an electric conveying unit, and the function of the electric conveying unit is to convey articles. In this embodiment, the electric conveying unit includes a conveyor belt 2 and two conveying frames 1. The two conveying frames 1 are arranged relatively parallel to each other, and a plurality of parallel conveying rollers 25 are provided between the two conveying frames 1. Both ends of the conveying roller 25 are rotatably connected (for example, rotatably connected through bearings) to the two conveying frames 1. The number of conveying rollers 25 is at least two, and the two conveying rollers 25 are at least respectively located at the two end portions of the conveying frame 1. The conveying roller 25 is located inside the conveyor belt 2, and the conveyor belt 2 is connected to the conveying roller 25. A motor (not shown in the figure) for driving the conveying roller 25 to rotate is provided on the conveying frame 1. The motor and one of the conveying rollers 25 can be directly coaxially connected (such as connected through a coupling), or can be connected through a speed reducer. Thus, the rotation of the motor drives the rotation of the conveying roller 25, and the conveying roller 25 drives the conveyor belt 2 to convey. A battery (not shown in the figure) for supplying power to the motor is installed on the conveying frame 1, and a charging port and a control switch for controlling the motor are provided on the conveying frame 1. The electric conveying unit in this embodiment is used to convey articles, and its structure and principle are very common in the prior art (common in the field of material conveying), and the specific structure will not be elaborated.

[0039] Combined with Figure 1 As shown, in order to reduce the sliding of articles on the conveyor belt 2 when the conveyor belt 2 conveys articles obliquely, in some embodiments, a plurality of laterally arranged anti-slip strips 3 are fixed (such as integrally fixed, fixed by screws, snap-fixed or adhesively fixed, etc.) on the outer side surface of the conveyor belt 2.

[0040] In this embodiment, a first support leg 11 is rotatably connected to one end of the electric conveying unit, and a second support leg 8 is rotatably connected to the other end of the electric conveying unit. The number of the first support legs 11 and the second support legs 8 is two each, and they are respectively located outside the two conveying frames 1. A handle 18 is connected to the second support leg 8. The length of the second support leg 8 is greater than the length of the first support leg 11. For example, the length of the second support leg 8 is 1 - 1.5 m, and the length of the first support leg 11 is 10 cm. The way the second support leg 8 rotates on the electric conveying unit is the same as the way the first support leg 11 is rotatably connected to the electric conveying unit. Taking the second support leg 8 as an example, the rotation mode of the second support leg 8 and the electric conveying unit is described as follows: Combined with Figure 6As shown, fixed shafts 20 are fixed (e.g., welded or bolted) to the outer side surfaces (the side away from the conveyor rollers 25) of the transfer frame 1. The ends of the second support legs 8 are provided with shaft cavities, and the fixed shafts 20 are inserted into the shaft cavities. By rotating the second support legs 8 on the fixed shafts 20, the rotational connection between the second support legs 8 and the electric transfer unit is achieved. To enable the second support legs 8 to automatically lock after rotating a certain angle, a plurality of card holes are provided on the circumferential side surface of the fixed shaft 20. The shapes of the card holes are hemispherical, and the plurality of card holes are circumferentially distributed along the circumferential side surface of the fixed shaft 20. A plurality of receiving grooves 23 are provided in the shaft cavities. The length directions of the plurality of receiving grooves 23 are all arranged along the radial direction of the fixed shaft 20, and the plurality of receiving grooves 23 are circumferentially distributed around the fixed shaft 20. A latch 21 is slidably provided in the receiving groove 23. One end of the latch 21 and the bottom of the receiving groove 23 are connected by a compression spring 24. The other end of the latch 21 is a latching end 22, and the latching end 22 is hemispherical and can be latched in the card hole. Thus, after the second support leg 8 rotates to a certain position and stops, the latching end 22 of the latch 21 is latched in the card hole, thereby realizing the locking of the second support leg 8, and the second support leg 8 will not rotate arbitrarily. When it is necessary to rotate the second support leg 8, a relatively large force is used to rotate the second support leg 8. The latching end 22 of the latch 21 withdraws from the card hole along the inner wall of the card hole and squeezes the compression spring 24, and the latch 21 retracts. In this way, the second support leg 8 will not be completely locked and can rotate normally. Therefore, the second support leg 8 in this embodiment can rotate relative to the fixed shaft 20, and when the second support leg 8 is stationary, a plurality of latching ends 22 are latched in the card holes, and the second support leg 8 can be in a stable stationary state.

[0041] The rotation mode of the first support leg 11 is the same as that of the second support leg 8, and both are realized through structures such as fixed shafts 20, shaft cavities, latches 21, and card holes, which will not be elaborated in this embodiment.

[0042] Combined with Figure 1 As shown, when the device is in the unfolded state, both the first support leg 11 and the second support leg 8 are vertically arranged, and the electric transfer unit is obliquely placed under the support of the first support leg 11 and the second support leg 8.

[0043] By rotating the second support leg 8, the length direction of the second support leg 8 is made the same as the length direction of the electric transfer unit, thereby realizing the storage of the device. Combined with Figure 2 and Figure 4 As shown, when the device is in the storage state, the length direction of the second support leg 8 is the same as the length direction of the electric transfer unit.

[0044] In this embodiment, rollers are provided at the bottom of the first support leg 11. The free end of the second support leg 8 in this embodiment is bent. Combined with Figure 4As shown, the free end of the second support leg 8 is provided with a first contact surface and a second contact surface for contacting the ground. A friction pad 9 is connected to the first contact surface. In the deployed state, combined with Figure 1 As shown, the friction pad 9 on the first contact surface contacts the ground, and the second contact surface does not contact the ground. The setting of the friction pad 9 enables the electric transmission unit to be in a stable inclined placement state. Combined with Figure 4 As shown, rollers are provided on the second contact surface at the free end of the second support leg 8. In the stored state, the second contact surface contacts the ground through the rollers, and the first support leg 11 and the second contact surface jointly support the electric transmission unit. The electric transmission unit can be stably placed flat on the ground, and the rollers on the first support leg 11 and the rollers on the second support leg 8 both contact the ground, and the device can move on the ground.

[0045] In order to improve the stability of the device when placed flat on the ground, a third support leg 13 is further provided on the electric transmission unit in this embodiment. Combined with Figure 4 As shown, the third support leg 13 is welded to the transmission frame 1. In this embodiment, it is specifically located at the end of the transmission frame 1 away from the first support leg 11. The length of the third support leg 13 is less than the length of the second support leg 8; in the stored state, the free end of the second support leg 8 is located between the first support leg 11 and the third support leg 13. In this way, the third support leg 13, the first support leg 11, and the second support leg 8 jointly support the device placed flat, and the device is more stable when placed flat on the ground. Rollers are also provided on the third support leg 13 in this embodiment, so as to facilitate the movement of the device when placed flat.

[0046] Combined with Figures 1 - 3 As shown, a placement table 6 is rotatably provided at one end of the electric transmission unit away from the first support leg 11. The specific rotation method is as follows: First connection blocks 17 are integrally formed or welded at the ends of the two transmission frames 1. The two first connection blocks 17 face each other, and the end of the placement table 6 is located between the two first connection blocks 17. The end of the placement table 6 rotates on the first connection block 17 by means of shaft and hole cooperation. A stabilizing rod 7 is rotatably connected to the electric transmission unit. The specific rotatable connection method is as follows: Combined with Figures 1 - 3 As shown, second connection blocks 16 are integrally formed or welded at the ends of the two transmission frames 1. The two second connection blocks 16 face each other, and the stabilizing rod 7 rotates on the second connection block 16 by means of shaft and hole cooperation. In Figure 2 In this embodiment, the relative relationship between the first connection block 17 and the second connection block 16 is: The second connection block 16 is close to the upper side of the conveyor belt 2, and the first connection block 17 is close to the lower side of the conveyor belt 2. The end of the stabilizing rod 7 away from the second connection block 16 and the end of the placement table 6 away from the first connection block 17 are detachably connected.

[0047] Thus, when the device is in the deployed state, the placement table 6 is rotated to a horizontal state, and the end of the stabilizing rod 7 away from the second connecting block 16 is connected to the end of the placement table 6 away from the first connecting block 17. Combined with Figure 7 as shown, at this time, the stabilizing rod 7 abuts against the end of the conveying frame 1 and cannot swing downward any further. Under the pulling action of the stabilizing rod 7, the placement table 6 is in a stable horizontal state. There are various detachable connection methods between the stabilizing rod 7 and the placement table 6. For example, pin connection, screw connection, hook connection, etc. The attached figure shows the connection method using a sampling hook. Specifically, a hook is provided at the free end of the stabilizing rod 7, and clamping shafts 15 are provided on both sides of the end of the placement table 6 away from the first connecting block 17. By hooking the hook on the clamping shaft 15, the detachable connection between the end of the placement table 6 and the stabilizing rod 7 is achieved. Of course, when using a hook for connection, in Figure 1 this state, the bent part of the hook needs to be long enough to extend below the clamping shaft 15, so as to prevent the clamping shaft 15 from detaching from the hook without being supported by the hook, and ensure that the hook can stably hook the clamping shaft 15.

[0048] When the device needs to be stored, the stabilizing rod 7 and the placement table 6 are separated. Combined with Figure 2 as shown, the stabilizing rod 7 is folded upward above the conveying frame 1, and at the same time, the placement table 6 is rotated so that the placement table 6 rotates below the conveyor belt 2, and the placement table 6 is attached to the conveying table, realizing the storage of the placement table 6. In order to improve the stability of the placement table 6 after storage, a hook 14 is rotatably mounted on the lower side surface of the conveying frame 1, and the clamping shaft 15 is hooked by the hook 14, thereby realizing the fixation of the placement table 6, and the placement table 6 can be in a stable state of being attached to the conveyor belt 2. It is easy to understand that after the hook 14 and the clamping shaft 15 are connected, by rotating the hook 14, the hook 14 can be separated from the clamping shaft 15, so that the placement table 6 is released from the restriction.

[0049] Thus, through the device of this embodiment, when in the deployed state, combined with Figure 1 as shown, both the first support leg 11 and the second support leg 8 are rotated to a vertical state, and the electric conveying unit is obliquely placed under the support of the first support leg 11 and the second support leg 8. At this time, the device can be used normally. The courier places multiple underground items (usually small items) one by one on the electric conveying unit. The conveyor belt 2 conveys the items from the bottom to the top direction, and the electric conveying unit conveys multiple items upward to the placement table 6. Then the courier stands up again and moves the items on the placement table 6 to the shelf for placement. In this way, the courier does not need to repeatedly bend down to pick up the items on the ground and place them on the shelf, reducing the burden on the waist and the labor intensity.

[0050] In the storage state (non-use state), the second support leg 8 is rotated relative to the electric conveying unit, and the length direction of the second support leg 8 is the same as the length direction of the electric conveying unit. At this time, the second support leg 8 and the electric conveying unit of the device are stored together. At the same time, the stabilizing rod 7 is disconnected from the placing table 6, and the placing table 6 is rotated. The placing table 6 rotates to the lower side of the electric conveying unit, and the clamping shaft 15 of the placing table 6 is connected to the hook 14. The stabilizing rod 7 is rotated to the upper side of the conveying frame 1, and the stabilizing rod 7 and the placing table 6 are respectively located on both sides of the electric conveying unit. At this time, the device is in the Figure 2 storage state, and the device can be placed flat on the ground under the bottom layer of the shelf or placed vertically against the wall. The device does not occupy a large storage space.

[0051] In addition, as shown in Figure 1 , in other embodiments, a pull rod 4 is rotatably provided at the top end of the second support leg 8. The setting of the pull rod 4 facilitates the holding or pulling of the device in the storage state to move the device placed flat on the ground on the ground. When the device is not in use, the pull rod 4 can also be folded and stored by rotation.

[0052] In summary, the device has a simple structure and is portable to operate. When the device is not in use, it can be folded and stored, which is convenient for placing the device. The device does not occupy a large space when placed. When in need of use, it can be unfolded to convey items upward. Compared with the prior art, the device has a simple structure and does not occupy a large space. Even in a narrow space, it can cooperate with people to work.

[0053] Embodiment 2 This embodiment is further optimized on the basis of Embodiment 1. As shown in Figure 1 , a storage bag 5 is detachably connected to the end of the placing table 6 of this embodiment away from the conveying frame 1. The specific detachable connection method is as follows: a card slot is provided at the end of the placing table 6, and a card block is fixed (such as glued) on the outer side of the top of the storage bag 5. The storage bag 5 and the placing table 6 are detachably connected by the card block being stuck in the card slot. Of course, in other embodiments, other detachable connection methods can also be adopted, such as connecting through Velcro, connecting through snap fasteners, etc.

[0054] Thus, when there are more items conveyed to the placing table 6, the items on the placing table 6 can be pushed by the items conveyed subsequently into the storage bag 5 for storage, avoiding the items on the placing table 6 from falling to the ground due to being too many.

[0055] In addition, for the storage bag 5, it can be set as a foldable storage bag, so that it can be folded and stored when not in use and does not occupy space.

[0056] For the specific structure of the foldable storage bag, it can adopt the following structure: As shown inFigure 8 As shown, the storage bag 5 includes a first hard board 28 and a second hard board 26. Both the first hard board 28 and the second hard board 26 can be made of wooden boards or plastic boards. A flexible folding part 27 is connected between the first hard board 28 and the second hard board 26. The flexible folding part 27 can be made of cloth or paper material. There are creases on the flexible folding part 27, which is convenient for folding. The bottom of the first hard board 28, the bottom of the second hard board 26 and the bottom of the flexible folding part 27 are connected (such as bonded or sewn). In this way, the first hard board 28, the second hard board 26 and the flexible folding part 27 enclose a storage cavity. When storing an object, separate the first hard board 28 and the second hard board 26, and the flexible folding part 27 unfolds, so that it can be used to store items. When there is no need to store items, make the first hard board 28 and the second hard board 26 approach each other, and the flexible folding part 27 folds, so as to realize the folding of the storage bag 5.

[0057] In the case where the first hard board 28 and the second hard board 26 are provided on the above storage bag 5, the clamping block can be bonded or fixed to the side of the top of the first hard board 28 by screws.

[0058] Embodiment 3 This embodiment further limits on the basis of Embodiment 1. One end of the electric transmission unit in this embodiment is detachably connected (such as connected by a clamping block or connected by a rope) to a freight car 10. There is a connecting block connected to the freight car in the figure, and the connecting block is stuck on both sides of the first support leg 11. Wheels are provided at the bottom of the freight car 10, and the inner bottom surface of the freight car 10 is inclined. The end of the inner bottom surface of the freight car 10 close to the electric transmission unit is the low end, and the end of the inner bottom surface of the freight car 10 far from the electric transmission unit is the high end. A side opening is provided on one side of the freight car 10 facing the electric transmission unit, and a vertically sliding pull-out plate is provided at the side opening.

[0059] Thus, place the items in the freight car 10, pull up the pull-out plate, the side opening of the freight car 10 opens, and the goods in the freight car 10 slide towards the electric transmission unit under the action of the bottom slope, and the items automatically slide onto the conveyor belt 2, and the conveyor belt 2 conveys the items upward, thus realizing the feeding of the object.

[0060] When the device is not in use usually, the freight car 10 can be detached from the electric transmission unit, and the freight car 10 does not affect the storage of the device.

[0061] Embodiment 4 This embodiment is improved on the basis of Embodiment 1. The placing table 6 in this embodiment is made of glass, and a scanning tool, such as a barcode scanner, is provided below the placing table 6.

[0062] Therefore, the code scanning tool is located below the placement table 6. Before the courier transfers the express items on the placement table 6 to the shelf, the courier scans the courier number on the courier package through the code scanning tool, thereby realizing courier tracking. The glass is transparent, and the placement table 6 will not hinder the code scanning tool from scanning the courier number.

[0063] Example 5 The difference between this embodiment and embodiment 2 is that this embodiment provides a different arrangement of the storage bag 5. Figures 9 - 12 As shown, in this embodiment, a pocket 35 is provided on the placement platform 6, and the placement platform 6 includes a shell 30 and a sliding plate 29. The pocket 35 is located in the shell 30. An end of the shell 30 away from the electric transmission unit is provided with an opening communicating with the pocket 35, and an end of the shell 30 close to the electric transmission unit is closed. The sliding plate 29 is slidably located in the pocket 35. Figure 9 The upper inner wall and the lower inner wall of the middle pocket cavity 35 are both provided with a limiting groove 32, and the top and the bottom of the sliding plate 29 are both fixed (for example, integrally fixed) with a limiting block 31, and the limiting block 31 is slidably arranged in the limiting groove 32. In this way, when the sliding plate 29 slides to the opening of the pocket cavity 35, the limiting block 31 abuts against the end of the limiting groove 32, and the sliding plate 29 will not be separated from the opening.

[0064] Combination Figure 12 As shown, the bottom of the sliding plate 29 facing the side of the opening is provided with a notch 36, combined with Figure 9 As shown, the end of the first hard plate 28 is located at the notch 36, and the end of the first hard plate 28 is connected to the notch 36 by a shaft. Figure 10 As shown, when the first hard plate 28 is rotated to a horizontal state, the top of the second hard plate 26 abuts against the right side surface of the sliding plate 29.

[0065] In this embodiment, the thickness between the upper and lower side walls of the sliding plate 29 is substantially the same as the thickness of the storage bag 5 after folding, the thickness of the bag cavity 35 in this embodiment is not less than the thickness of the storage bag 5 after folding, and the width of the bag cavity 35 is substantially equal to the width of the storage bag 5. Therefore, the storage bag 5 can be relatively well stored in the bag cavity 35.

[0066] In this embodiment, a flexible block 33 (such as rubber material) is connected between the bottom of the first hard plate 28 and the bottom of the second hard plate 26. The flexible block 33 is flexible and will not affect the relative rotation of the bottom of the first hard plate 28 and the bottom of the second hard plate 26. The flexible folding portion 27 is also connected to the flexible block 33. Figure 9 As shown, the arrangement of the flexible block 33 makes the bottom plane of the first hard plate 28 and the bottom plane of the second hard plate 26 connected. Figure 8 It can be in a planar state, so that the opening of the bag cavity 35 can be better sealed.

[0067] Thus, in combination with Figure 9 as shown, after folding the storage bag 5, it is pushed into the bag cavity 35, and the sliding plate 29 moves to one end of the placing table 6 close to the electric conveying unit ( Figure 9 left end), and the bottom of the storage bag 5 seals the opening at the right end of the placing table 6. In this way, when the device is not in use, the storage bag 5 is located in the bag cavity 35 and does not occupy space, and the storage bag 5 will not affect the folding of the placing table 6 to the lower side of the electric conveying unit and being in a fitting storage state with the conveyor belt 2.

[0068] When it is necessary to take out the storage bag 5, pull the bottom of the storage bag 5 to the right in Figure 9 (for the convenience of pulling the storage bag 5, in other embodiments, a pulling rope 34 can be adhered to the bottom of the storage bag 5, and by pulling the pulling rope 34, the storage bag 5 is pulled out of the bag cavity 35). The storage bag 5 slides out of the bag cavity 35, and the storage bag 5 drives the sliding plate 29 to slide to the right. Finally, the sliding plate 29 slides to the opening of the bag cavity 35, and the limiting block 31 abuts against the right end of the limiting groove 32, and the sliding plate 29 no longer slides to the right. At this time, as Figure 10 shown. Then rotate the storage bag 5, and the first hard plate 28 rotates on the sliding plate 29. In combination with Figure 11 as shown, the storage bag 5 is rotated to a vertical placement state, and the first hard plate 28 and the second hard plate 26 are moved away from each other to open the storage bag 5, so that items can be received. In this embodiment, the setting of the notch 36 enables the sliding plate 29 not to hinder or interfere with the rotation of the first hard plate 28.

[0069] When the placing table 6 is not in use, make the first hard plate 28 and the second hard plate 26 approach each other, fold the storage bag 5, and fold the storage bag 5 in Figure 11 , and fold it to the Figure 10 state, so that the storage bag 5 rotates to a state substantially in the same plane as the placing table 6. Then push the storage bag 5 and the sliding plate 29 into the bag cavity 35, and the placing table 6 stores the storage bag 5, and the bottom of the storage bag 5 seals the opening of the bag cavity 35. Of course, it is easy to understand that in other embodiments, in order to improve the stability of the storage bag 5 in the bag cavity 35, the friction between the inner wall of the bag cavity 35 and the sliding plate 29 can be increased (by fixing a rubber friction belt on the outer side wall of the sliding block with screws), to prevent the storage bag 5 from automatically falling out of the bag cavity 35.

[0070] The above embodiments illustrate the application of the present device in the express delivery field. Of course, the use of the present device is not limited to the express delivery field. The present device can be used in any field involving item transfer. For example, it can be applied to farms, rural areas, etc. to convey and transport agricultural products. In this way, people can uniformly convey multiple agricultural products piled up in the fields or on the ground upward to the placement table 6 (at this time, the placement table 6 can be used as a packing table) through the conveyor belt 2, and then stand up to uniformly package the agricultural products on the placement table 6, without having to individually take the agricultural products on the ground to the placement table 6 for packaging, which greatly saves physical strength and frequent bending. After the agricultural products are packed, they can be sold outside.

[0071] Of course, in other embodiments, when the present device is used outdoors, a solar panel can also be installed at the placement table 6 (the solar panel is placed inside the placement table 6, and the placement table 6 is transparently arranged). The solar panel is connected to the motor. The solar panel absorbs solar energy and converts it into electrical energy for the motor to use, so that it can be used outdoors.

[0072] In addition, in other embodiments, the pull rod 4 can also be telescopically arranged, so as to adjust the length of the pull rod 4 according to the actual situation. Elastic buffer structures (such as a combination of elastic buffer rods and springs) can be provided at the bottoms of the first support leg 11 and the second support leg 8, so that the device vibrates less when moving on uneven ground.

[0073] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics that are well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
