Technical Field

[0001] The utility model relates to the field of logistics sorting, in particular to a cargo unloading device and a storage device convenient for unloading. Background Art

[0002] In logistics, goods often need to be stored in boxes.

[0003] When unloading is required, it is often necessary to manually unload the goods from the outside to the inside.

[0004] In order to facilitate unloading, the utility model patent with the authorization announcement number CN220536551U discloses a container that can facilitate unloading. At that time, the inner end of the placement plate is driven to be raised by a telescopic rod, so that the goods can be unloaded.

[0005] This structure is relatively complex, and a telescopic support rod needs to be set under the placement board, which takes up a large space and affects the storage capacity of the container. More importantly, in this structure, when the placement board is tilted, the goods on the inside may be pressed against the top plate of the container, posing a risk of damage to the goods. Utility Model Content

[0006] The purpose of the utility model is to solve the above problems existing in the prior art and to provide a cargo unloading device and a storage device which is convenient for unloading.

[0007] The purpose of the utility model is achieved through the following technical solutions:

[0008] The unloading device includes an unloading belt, a push stopper located at the first end of the unloading belt is arranged above the unloading belt, the second end of the unloading belt is wound around a supporting wheel and then wound around a winding mechanism, and the winding mechanism drives the unloading belt to rewind so that the push stopper on the unloading belt follows the unloading belt and moves horizontally toward the winding mechanism.

[0009] Preferably, the unloading belt is a belt or a chain belt.

[0010] Preferably, the unloading belt is a chain belt and is made of friction-reducing material.

[0011] Preferably, after the chain belt is unwound from the winding mechanism, a pattern is formed on its upward first surface.

[0012] Preferably, the supporting wheel is a sprocket, and a tooth groove matching the sprocket is provided on the second surface of the unloading belt corresponding to the first surface.

[0013] Preferably, the unloading belt is wound on the winding mechanism in the form of an Archimedean spiral.

[0014] Preferably, the unloading belt is connected to the supporting wheel via a limiting roller.

[0015] Preferably, the winding mechanism is provided with a roller for keeping the winding portion of the unloading belt in the form of an Archimedean spiral.

[0016] Preferably, both sides of the unloading belt are respectively provided with limiting members for cooperating in limiting the position of the unloading belt.

[0017] A storage device that is convenient for unloading, comprises a box body, and also comprises an unloading device as described above, wherein the first end of the unloading belt of the unloading device can extend into the box body, the supporting wheel is located outside the box body, and the portion of the unloading belt between the push stopper and the supporting wheel is laid on the bottom plate of the box body.

[0018] Preferably, a buffer curtain is provided at the outlet of the box.

[0019] The advantages of the technical solution of the utility model are mainly reflected in:

[0020] The structure of the utility model is provided with a discharge belt, which can be laid on the bottom of the box and the goods can be placed thereon. When unloading is needed, the discharge belt is wound up by the winding mechanism, so that the pushing stopper can stably push the goods on the discharge belt to the outside of the box, thereby realizing unloading. In this structure, the discharge belt has a very small and negligible effect on the storage capacity of the box. At the same time, the unloading is carried out in a translational manner, and there is no problem of pressure damage to the goods. At the same time, the goods will not have a large relative displacement during the unloading and movement process, so that the unloaded goods can be unloaded in batches with high efficiency and can be smoothly transferred to the next conveying system, and there will be no problem of scattered dumping of goods.

[0021] The utility model adopts a chain belt structure, which can better adapt to the influence of the uneven bottom of the container on the conveying of the unloading belt. At the same time, the unloading belt adopts a special low-friction composite plastic to ensure the tensile strength while effectively reducing the influence of the friction on the bottom of the unloading belt during unloading.

[0022] The utility model adopts a winding mechanism to effectively simplify the structure, and adopts a special winding form to effectively protect the unloading belt and reduce the running noise.

[0023] In this solution, a buffer curtain with a certain damping effect is added at the outlet of the container to prevent the goods from falling directly from high places during the unloading process, so as to achieve the purpose of protecting the goods and improving the separation effect. At the same time, a conveyor line is set at the outlet to facilitate the direct transfer of the exported goods to the downstream equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The purpose, advantages and features of the present invention will be illustrated and explained through the non-limiting description of the following preferred embodiments. These embodiments are only typical examples of the application of the technical solution of the present invention, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.

[0030] In the description of the scheme, it should be noted that the terms "center", "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] The unloading device disclosed by the utility model is described below in conjunction with the accompanying drawings. Figure 1 As shown, it includes a unloading belt 100, and a push stopper 200 is arranged above the unloading belt 100 and located at the first end of the unloading belt. The second end of the unloading belt 100 is wound around a supporting wheel 300 and then wound around a winding mechanism 400. When the winding mechanism 400 drives the unloading belt 100 to rewind, the push stopper 200 on the unloading belt 100 follows the unloading belt 100 and moves horizontally toward the winding mechanism 400.

[0032] Specifically, the unloading belt 100 is a belt or a chain belt, and the width and length of the belt or chain belt can be designed as needed and are not limited here.

[0033] As attached Figure 2As shown, the unloading belt 100 is a chain belt, which is formed by connecting a plurality of chain links 110. Both ends of the chain links 110 are formed with mutually staggered connecting plates 111. The connecting plate 111 at one end of one chain link 110 can be embedded between the connecting plates 111 at the other end of another chain link 110, and connected by bolts 120 and nuts 130 that penetrate through the connecting plates 111. In addition, the unloading belt can be made of anti-friction material.

[0034] As attached Figure 2 As shown, a pattern 140 is formed on the first surface of the chain belt, and the pattern 140 is realized by setting protrusions and / or grooves on the first surface, which can effectively increase the friction between the chain belt and the goods thereon, thereby avoiding relative sliding between the two and affecting unloading.

[0035] As attached Figure 3 As shown, the height of the support wheel 300 can be designed as required. Preferably, when the unloading belt 100 is located on a plane, the top height of the support wheel 300 is equivalent to the height of the plane where the unloading belt 100 is located. The support wheel 300 can be a pulley. More preferably, the support wheel 300 is a sprocket. Moreover, the number of the support wheels 300 can be designed as required. For example, the support wheel 300 is a sprocket with multiple circles of teeth arranged along its axial direction, or the support wheel 300 is a plurality of sprockets, which are distributed below the unloading belt 100 along the width direction of the unloading belt 100. Correspondingly, the second surface of the unloading belt 100 corresponding to the first surface is provided with a tooth groove 150 matching the sprocket.

[0036] As attached Figure 3 As shown, in order to prevent the unloading belt 100 from separating from the supporting wheel 300 or jumping during operation, the unloading belt 100 is connected to the supporting wheel 300 via a limiting roller 500. The number of the limiting rollers 500 can be designed as needed. Preferably, the limiting rollers 500 are attached to the upper and outer sides of the corner position of the unloading belt 100.

[0037] Furthermore, the support wheel 300 is disposed on the mounting frame 420 of the winding mechanism 400 , and can also be connected to a motor that drives its rotation, so that it can effectively cooperate with the winding mechanism 400 to retract and release the unloading belt 100 .

[0038] As attached Figure 3As shown, the winding mechanism 400 may be a known feasible winding machine, which may include a reel 410, the reel 410 is rotatably arranged on a mounting frame 420, the reel 410 is connected to a motor (not shown in the figure) that drives its rotation, and the motor may connect the reel 410 and the support wheel 300 through a synchronous belt mechanism (not shown in the figure), so as to drive them to move synchronously. Of course, in other embodiments, the reel 410 may also be connected to a hand crank instead of a motor, and the unloading belt 100 may be wound and unwound by manual drive.

[0039] As attached Figure 3 As shown, the second end of the unloading belt 100 is fixed on the reel 410, and at the same time, a group of rollers 430 are also provided on the mounting frame 420, and the group of rollers 430 make the unloading belt 100 be wound on the winding mechanism 400 in the form of an Archimedean spiral. This can effectively avoid contact between the unloading belts 100, thereby generating a lot of wear and noise.

[0040] As attached Figure 4 As shown, in order to prevent the two sides of the unloading belt 100 extending out of the winding mechanism 400 from swinging, limiting members 600 are respectively provided on both sides of the unloading belt 100 to cooperate with the unloading belt 100 to limit the position. The limiting members 600 can be, for example, L-shaped limiting strips, which can be made of anti-friction materials, such as ultra-high molecular weight polyethylene (UHMWPE) or high-performance polyethylene (HPPE) or polytetrafluoroethylene. Of course, the limiting strips can also adopt other feasible forms to limit the two sides of the unloading belt 100, for example, a row of limiting rollers 500 are respectively provided on both sides of the unloading belt 100, and the axes of the limiting rollers 500 move along the vertical direction.

[0041] As attached Figure 4 As shown, the shape of the push stopper 200 can be designed as needed, for example, it can be a vertical plate. More preferably, the push stopper 200 includes a main body 210 and a convex portion 220 protruding from the side of the main body 210 toward the winding mechanism 400, the convex portion 220 is located at the bottom of the main body 210 and the top of the convex portion 220 is an inclined surface, and the inclined surface connects one side of the main body 210 higher than the other opposite side. In this way, when unloading, due to the effect of inertia, the upper layer of goods can stick to the part of the main body 210 located near the convex portion 220, thereby preventing them from falling from the outer side during movement.

[0042] Guide wheels 230 and limit wheels 240 are also provided on both sides of the push stop 200. The guide wheels 230 and limit wheels 240 cooperate with external mechanisms to make the push stop move more smoothly.

[0043] Example 2

[0044] This embodiment discloses a storage device that is convenient for unloading. Figure 5 As shown, it includes a box body 700, and the box body 700 can be any known structure with storage space, such as a container, a carriage, etc. The storage device also includes the unloading device as described above, the first end of the unloading belt 100 of the unloading device can extend into the box body 700, the support wheel 300 is located outside the box body 700, the part of the unloading belt 100 located between the push stopper 200 and the support wheel 300 is laid on the bottom plate of the box body 700, and the winding mechanism is located below the support wheel 300 and can be fixed on a fixing frame 710 outside the box body.

[0045] Furthermore, a conveyor 800 is also provided outside the outlet of the box 700, and the conveyor 800 is used to transport the goods discharged from the unloading device to the subsequent logistics system. The conveyor 800 can be a known belt conveyor or roller conveyor 800, etc., which can be fixed on the fixed frame 710 provided outside the outlet of the box 700. At the same time, the conveyor 800 can be one section or multiple sections. For example, in this embodiment, the conveyor 800 is two sections. One conveyor 800 close to the box 700 is tilted so that the low-level goods can smoothly enter the conveyor 800, and the other conveyor 800 is horizontally arranged to facilitate cooperation with the subsequent logistics system. Furthermore, a connection block 810 located at the input end of the tilted conveyor 800 is also provided on the fixed frame 710. The connection block 810 is a triangular block and maintains a small gap with the unloading belt 100, so that the goods on the lower layer can be better introduced into the tilted conveyor 800.

[0046] A buffer curtain 900 is provided at the exit of the box 700. The buffer curtain 900 can provide a certain degree of protection for the goods stacked high during the unloading and falling process through the damping effect of the buffer curtain 900. The buffer curtain 900 is installed on the fixing frame 710 outside the container. The buffer curtain 900 needs to cover most of the cross-sectional position of the container exit. Preferably, in this embodiment, the buffer curtain 900 uses a thicker polyurethane material, and the thickness can be set to 10-20mm to increase the buffering and damping effect of the goods.

[0047] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
