For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0036] Embodiment 1

[0037] like Figures 1 to 4 As shown, this embodiment discloses a sorting trolley, which can prevent items from sliding out of the sorting trolley, improve the stability during item sorting, and can also block items or foreign objects from entering under the conveyor belt, prevent the conveyor belt from getting stuck, and avoid malfunction and damage to the sorting trolley.

[0038] like Figure 1 and Figure 4 As shown, the sorting trolley includes a frame 1, on which a drivable conveyor belt 2 is arranged, and side blocks 3 are arranged on both sides of the conveyor belt 2 on the frame 1. The conveyor belt 2 is configured to transfer the sorted items 100 on the sorting trolley to the next process, and the side blocks 3 are configured to limit the displacement of the sorted items 100 along the moving direction of the sorting trolley ( Figure 1 and Figure 4 For example, the conveyor belt 2 is a flat conveyor belt, a patterned conveyor belt or a felt conveyor belt, etc., and the side stopper 3 is a flat plate structure that can be set up on the frame 1.

[0039] like Figure 1 , Figure 2 and Figure 4As shown, at least two mobile stops 4 are arranged at intervals on the conveying direction of the conveyor belt 2, and two adjacent mobile stops 4 can be surrounded by two side stops 3 to form a limited space, and the items 100 to be sorted are placed in the limited space. Sorting items of different shapes can be confined in the limited space to prevent the sorting items 100 from moving outside the sorting trolley, so as to ensure the smooth progress of the sorting process and avoid damage to the sorting items 100. A fixed stop 5 is also provided at the end of the frame 1, and the fixed stop 5 is located below the conveyor belt 2, and the fixed stop 5 is parallel to the mobile stop 4. When the mobile stop 4 moves with the conveyor belt 2 to the top of the fixed stop 5, the fixed stop 5 and the mobile stop 4 can contact or form a clearance fit. Such a setting can prevent items or other foreign objects from moving with the conveyor belt to the bottom of the conveyor belt 2, prevent the conveyor belt 2 from getting stuck, and avoid failure and damage to the sorting trolley, thereby improving the sorting efficiency and safety of the items.

[0040] For example, when the movable stopper 4 moves with the conveyor belt 2 to the position directly above the fixed stopper 5, the fixed stopper 5 and the movable stopper 4 are clearance-matched, such as Figure 2 As shown, the gap between the fixed stopper 5 and the movable stopper 4 is defined as B, and the value of B can be but is not limited to 10 mm, 20 mm, 30 mm, as long as it is set small enough in advance according to the type and size of the object 100 to be sorted, the height of the movable stopper 4 and the height of the fixed stopper 5.

[0041] In another optional embodiment, the fixed stopper 5 can also be designed to be in contact with the movable stopper 4, that is, when the movable stopper 4 reaches directly above the fixed stopper 5, the fixed stopper 5 and the movable stopper 4 are aligned and in contact or partially overlapped, so that the fixed stopper 5 can effectively prevent objects or other foreign objects from moving with the conveyor belt 2 to the bottom of the conveyor belt 2. Exemplarily, the contact parts of the fixed stopper 5 and the movable stopper 4 are both made of flexible materials so that the two can be in flexible contact, thereby preventing the fixed stopper 5 and the movable stopper 4 from being damaged and extending their service life.

[0042] Preferably, fixed stoppers 5 are provided at both ends of the vehicle frame 1, and the conveyor belt 2 can be driven in both directions. In this way, no matter the conveyor belt 2 is driven in the forward direction or the reverse direction, the fixed stoppers 5 can prevent objects or other foreign objects from entering under the conveyor belt 2. In other words, the sorting trolley of this embodiment can achieve bidirectional blocking of the sorted objects 100 or foreign objects, further improving the blocking effect of the sorted objects 100 and foreign objects.

[0043] Of course, in other embodiments, if the conveyor belt 2 is only for unidirectional transmission, the above-mentioned fixed stopper 5 can be disposed at only one end of the frame 1 in the transmission direction of the conveyor belt 2 .

[0044] Optionally, a plurality of teeth may be provided on the movable stopper 4 and the fixed stopper 5 to improve the blocking effect on objects and foreign matter. Figure 2 As shown, the movable stopper 4 is provided with a plurality of first teeth 41 along its extension direction, and the fixed stopper 5 is provided with a plurality of second teeth 51 along its extension direction, and the plurality of first teeth 41 can be interlocked with the plurality of second teeth 51. The arrangement of the first teeth 41 and the second teeth 51 enables the movable stopper 4 to block more shapes of objects or foreign objects, especially flat objects or foreign objects, when it is located directly above the fixed stopper 5, thereby further improving the blocking effect of the fixed stopper 5.

[0045] For example, Figure 1 and Figure 4 As shown, in this embodiment, the side block 3, the mobile block 4 and the fixed block 5 are all flat plate structures. Among them, only two mobile blocks 4 are set on the conveyor belt 2, and the two mobile blocks 4 are respectively located at the two ends of the conveyor belt 2, and the extension direction of the two mobile blocks 4 is perpendicular to the transmission direction of the conveyor belt 2. The limiting space formed by the two mobile blocks 4 and the two side blocks 3 is a square space, which can limit the sorting objects 100 of small size and any shape.

[0046] In other embodiments, the movable stopper 4 may also be disposed obliquely on the conveyor belt 2 as long as the normal transmission of the conveyor belt 2 is not hindered.

[0047] In addition, if Figure 1 and Figure 2 As shown, in this embodiment, a plurality of trapezoidal first teeth 41 are arranged at intervals on the movable stopper 4, and a plurality of triangular second teeth 51 are arranged at intervals on the fixed stopper 5. When the movable stopper 4 moves with the conveyor belt 2 to the top of the fixed stopper 5, the first teeth 41 and the second teeth 51 are engaged with each other. At the same time, a gap B is maintained between the first teeth 41 and the second teeth 51, and the gap B is smaller than the height of the first teeth 41 and the second teeth 51.

[0048] In other embodiments, the first teeth 41 and the second teeth 51 may both be designed as triangular teeth, or may both be set as trapezoidal teeth, as long as a plurality of first teeth 41 and a plurality of second teeth 51 can be engaged with each other.

[0049] Alternatively, if Figure 1 and Figure 2 As shown, a fixing member 11 is provided at the end of the frame 1 below the conveyor belt 2, and the fixing stopper 5 is detachably mounted on the fixing member 11. Such a configuration can facilitate the replacement of the fixing stopper 5 by the staff, so as to reduce the assembly and maintenance costs of the sorting trolley.

[0050] Alternatively, if Figure 1 and Figure 3As shown, in this embodiment, the fixing member 11 includes a first fixing plate 111, a second fixing plate 112 and a fastener, the first fixing plate 111 is fixedly connected to the frame 1, and the fixing stopper 5 is sandwiched between the first fixing plate 111 and the second fixing plate 112, and is fixed to the first fixing plate 111 and the second fixing plate 112 by the fastener. The fixing stopper 5 is installed by clamping, and the disassembly and assembly operation is simple and easy to implement. Specifically, a connecting plate is provided at each end of the first fixing plate 111, and the two connecting plates are fixedly connected to the opposite sides of the frame 1. The first fixing plate 111 is provided with a plurality of first through holes 1111 along its extension direction, the second fixing plate 112 is provided with a plurality of second through holes 1121 corresponding one-to-one to the plurality of first through holes 1111 along its extension direction, the fixing block 5 is provided with a plurality of third through holes 52 corresponding one-to-one to the plurality of first through holes 1111, the first fixing plate 111 and the second fixing plate 112 are located on both sides of the fixing block 5, and the fasteners pass through and are fastened to the first through holes 1111, the third through holes 52 and the second through holes 1121 in sequence, so as to clamp the fixing block 5 between the first fixing plate 111 and the second fixing plate 112.

[0051] Exemplarily, the fasteners are bolts and nuts, the screw rod of the bolt passes through the first through hole 1111, the third through hole 52 and the second through hole 1121, the head of the bolt abuts against the side of the first fixing plate 111 away from the fixing stopper 5, the nut abuts against the side of the second fixing plate 112 away from the fixing stopper 5, and is threadedly connected with the bolt; the head of the bolt abuts against the side of the second fixing plate 112 away from the fixing stopper 5, the nut abuts against the side of the first fixing plate 111 away from the fixing stopper 5, and is threadedly connected with the bolt. The threaded connection has the characteristics of tight connection and simple operation.

[0052] Furthermore, a portion of the first through-hole 1111 on the first fixing plate 111 is a strip-shaped hole, which makes it easier to align the third through-hole 52 and the second through-hole 1121 when threading the bolts, has a high fault tolerance rate, and reduces the difficulty of assembly.

[0053] In other embodiments, a card slot is provided on the fixing member 11, and the fixing stopper 5 is carded in the card slot. The fixing stopper 5 is installed by carding, and the disassembly and assembly operation is simple and easy to implement. Specifically, elastic limiting parts are provided on both sides of the slot position of the card slot, and the fixing stopper 5 includes a card connection part and a main body part. The thickness of the card connection part is greater than the thickness of the main body part, and the thickness of the card connection part is less than the width of the card slot, and the second tooth 51 is provided on the main body part. When installing the fixing stopper 5, align the card connection part with the card slot and insert it. During this process, the elastic limiting part is squeezed to produce elastic deformation. When the card connection part is inserted into the card slot, the main body part is clamped by the two elastic limiting parts under the action of elastic force, thereby limiting the fixing stopper 5 from being separated from the fixing member 11. When disassembling the fixing stopper 5, the fixing stopper 5 can be pulled out by applying force to overcome the elastic force of the elastic limiting part.

[0054] Alternatively, if Figure 1 and Figure 2 As shown, the frame 1 includes a first support member 12 and a second support member 13, the first support member 12 and the second support member 13 are arranged at intervals, the conveyor belt 2 is located between the first support member 12 and the second support member 13, and the first support member 12 and the second support member 13 are both provided with a side stopper 3. One end of the fixing member 11 is connected to the first support member 12, and the other end of the fixing member 11 is connected to the second support member 13. The fixing member 11 connects and fixes the first support member 12 and the second support member 13 together, thereby improving the stability of the frame 1.

[0055] Exemplarily, the first support member 12 and the second support member 13 are both L-shaped structures, and the two L-shaped structures are arranged in mirror symmetry. The long sides of the L-shaped structures are placed vertically for connecting with the fixing members 11 to form the frame 1, and the short sides of the L-shaped structures are placed horizontally for supporting the side stoppers 3.

[0056] Alternatively, if Figure 4 As shown, the sorting trolley includes a power mechanism, an active roller 6 and a driven roller, the active roller 6 and the driven roller are both rotatably connected to the first support member 12 and the second support member 13, the conveyor belt 2 is wound around the active roller 6 and the driven roller, and the output end of the power mechanism is connected to the active roller 6 for driving the active roller 6 to drive the conveyor belt 2 and the driven roller to drive, so as to transport the sorted items 100 on the conveyor belt 2 to the designated position. In this embodiment, the power mechanism includes a motor, and the output end of the motor is directly connected to the active roller 6 to drive the active roller 6 to rotate. Alternatively, the power mechanism includes a motor and a pulley transmission mechanism (or a gear transmission mechanism), and the output end of the motor is connected to the active roller 6 through the pulley transmission mechanism or the gear transmission mechanism to drive the conveyor belt 2 to drive.

[0057] The side stopper 3 and the movable stopper 4 of this embodiment are both made of flexible materials. The side stopper 3 and the movable stopper 4 made of flexible materials can buffer the sorting objects 100 when the sorting objects 100 collide with them, effectively preventing the sorting objects 100 from bumping in the limited space, and reducing the damage rate of the sorting objects during the sorting process.

[0058] Exemplarily, the flexible material is rubber or silicone, etc., which has good cushioning effect and long service life.

[0059] Optionally, the sorting trolley includes a running assembly disposed at the bottom of the frame 1, and the running assembly is configured to drive the frame 1 to move.
