Description

Technical Field

[0001] This utility model belongs to the field of material transportation technology, and in particular relates to a heavy-duty mobile unloading device. Background Technology

[0002] In scenarios such as strip material yards and elevated corridors, traditional fixed unloading equipment struggles to meet the demands of multi-point material placement and dynamic unloading. Mobile unloading vehicles, however, can move freely along conveyor tracks, enabling unloading at any location and thus adapting to the complex material distribution needs of large-scale industrial settings. Compared to fixed equipment like plow-type unloaders, mobile unloading vehicles offer advantages such as multi-point unloading, low material loss, and adaptability to demanding scenarios. However, the following problems still exist in the use of mainstream conveyor belt mobile unloading vehicles currently on the market: To adapt to the needs of unloading scenarios, mobile unloading vehicles typically use single-sided or double-sided unloading ports to meet unloading requirements. For double-sided unloading, materials enter the discharge assembly from the conveyor belt and are then discharged from the two discharge ports to the storage areas on both sides of the unloading vehicle. When the material accumulated in the storage area reaches a certain volume, the unloading vehicle moves to the next storage area. However, the material distribution on the conveyor belt is not always uniform, and the amount of material discharged into the storage areas on both sides is inconsistent. There may be a situation where one side is full and the other side is not full, resulting in wasted storage space. Mobile unloading vehicles need to move along tracks. If there are foreign objects piled up on the tracks, the wheels of the unloading vehicle may come off the tracks, and in severe cases, the unloading vehicle may tip over. Because the discharge assembly cannot fit snugly against the conveyor belt, material may fly out from the gap between the conveyor belt and the discharge assembly, resulting in material waste.

[0003] To address these issues, we provide a heavy-duty mobile unloading device. Utility Model Content

[0004] The purpose of this utility model is to provide a heavy-duty mobile unloading device. By setting baffles, rotating plates, brushes, baffle plates, inclined plates and pads, it solves the problem of different material accumulation in the storage areas on both sides of the mobile unloading vehicle, the problem of foreign objects on the track affecting the movement, and the problem of materials flying out from the gap between the discharge component and the conveyor belt.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a heavy-duty mobile unloading device, including a base, a discharge component, and diagonal braces; two diagonal braces are symmetrically arranged above the base, and a discharge component is arranged on one side of the base and the diagonal braces. Frames are fixedly connected to both sides of the base, and a traveling component is rotatably connected inside the frame. A longitudinal brace is fixedly connected to the higher end of the diagonal brace near the discharge component. Support roller groups are arranged in the middle and at the top of the lower end of the diagonal brace. A through groove is opened on the side of the base near the discharge component, and a redirecting roller is rotatably connected inside the through groove and between the two longitudinal braces. When carrying out material conveying and unloading operations, the conveyor belt is introduced from the front end of the unloading car. Supported by two support roller groups, it winds from the higher end of the upper redirecting roller to the lower end of the lower redirecting roller, and finally leads to the rear of the unloading car. During this process, the material enters the discharge component and finally falls into the storage areas on both sides of the unloading car through the discharge component. After the material in the storage area reaches the accumulation threshold, the traveling component rotates to move the unloading car to the next storage area. The discharge assembly includes two symmetrically arranged side plates. A vertical plate one is fixedly connected between the two side plates at a position away from the base. A vertical plate two is fixedly connected at the lower part of the two side plates near the base. Two baffles are symmetrically fixedly connected at the upper part between the opposing surfaces of vertical plate one and vertical plate two. A rotating plate is rotatably connected at the lower part between the opposing surfaces of vertical plate one and vertical plate two. The discharge assembly also includes two symmetrically arranged discharge pipes. Each discharge pipe is fixedly connected to the side plate above it. The discharge pipe is located below the rotating plate. The side plate, vertical plate one, and vertical plate two form the frame of the discharge assembly. Rotating the rotating plate causes its lower inclined surface to adhere to the inner wall of the discharge pipe on the left. At this time, the lower inclined surface of the baffle on the right adheres to the upper inclined surface of the rotating plate, preventing the rotating plate from continuing to rotate. After the material on the conveyor belt reaches the highest point, it falls into the discharge assembly. Under the protection of the two baffles, it falls onto the upper inclined surface of the rotating plate and moves along the rotating plate, eventually being discharged from the discharge pipe on the left and falling into the storage area on the left side of the unloading vehicle. After the storage area on the left is full, rotating the rotating plate causes its lower inclined surface to adhere to the inner wall of the discharge pipe on the right. At this time, the lower inclined surface of the baffle on the left adheres to the upper inclined surface of the rotating plate, and the material moves along the rotating plate and is discharged from the discharge pipe on the right, falling into the storage area on the right side of the unloading vehicle. After the storage area on the right is full, the unloading vehicle can be moved to the next storage area. Both ends of the bottom of the frame away from the base are fixedly connected to connecting rods, and the bottom of the connecting rods are fixedly connected to brushes. The inclined surface of the diagonal brace and the top of the longitudinal brace are fixedly connected to a baffle plate. When the unloading car moves, the brush located in front of the unloading car in the direction of movement cleans foreign objects on the track to prevent foreign objects from affecting the movement of the unloading car. The baffle plate is set so that the material on the conveyor belt will not fly out and fall onto the track.

[0006] Furthermore, a motor box is fixedly connected to one side of the base away from the through slot. A motor is installed inside the motor box. A pulley is rotatably connected to the side of the motor box away from the base. The shaft of the output end of the motor extends through the motor box and is connected to the pulley for transmission. A pulley is externally connected to the end of the walking component away from the discharge component that is close to the motor. A transmission belt is connected between the two pulleys. When motor one is started, the shaft at the output end of motor one rotates, which drives the pulley connected to the shaft to rotate, which in turn drives the transmission belt and the pulley connected to the traveling component to rotate, thereby driving the traveling component to rotate and realizing the movement of the unloading vehicle.

[0007] Furthermore, three support columns with progressively increasing heights are fixedly connected to both sides of the top of the base. The tops of the three support columns on the same side of the base are fixedly connected to a diagonal brace. The lower end of the diagonal brace is fixedly connected to the frame away from the discharge assembly. The frame and the three support columns provide support for the diagonal brace and the redirecting roller.

[0008] Furthermore, the two middle support columns are fixedly connected to a cross brace on the upper part near the discharge assembly. The support roller group at the higher position is fixedly connected to the frame away from the discharge assembly. The support roller group at the lower position is fixedly connected to the cross brace. The frame and the diagonal brace provide support for the lower support roller group. The diagonal brace and the cross brace provide support for the upper support roller group.

[0009] Furthermore, two support columns are symmetrically fixedly connected at the top of the frame below the discharge assembly, away from the base. The support columns are fixedly connected to the side plate above them. The upper part of the side plate has a groove, and the longitudinal brace is inserted into the groove for fixation. The support columns and the longitudinal brace provide support for the discharge assembly.

[0010] Furthermore, a top plate is fixedly connected to the top of both side plates, and an inclined plate is fixedly connected to the top of the vertical plate. The two ends of the inclined plate are fixedly connected to the two side plates respectively, and a pad is provided at the top of the inclined plate. The inclined plate is located below the upper redirecting roller, and the padding strip is attached to the surface of the conveyor belt. There is no longer a gap between the discharge component and the conveyor belt. The material will only enter the discharge component and eventually be discharged from the discharge pipe.

[0011] Furthermore, a second motor is fixedly connected to the side of the first vertical plate away from the second vertical plate, and the shaft of the output end of the second motor extends through into the first vertical plate and is connected to the rotating plate for transmission.

[0012] When the rotating plate needs to be rotated, start motor two. The shaft at the output end of motor two rotates in the forward or reverse direction, causing the material to fall into the storage area on the left or right.

[0013] This utility model has the following beneficial effects: This invention solves the problem of inconsistent material discharge from two discharge pipes by setting up baffles and rotating plates. During discharge, the rotating plate rotates so that its lower inclined surface fits against the inner wall of the left discharge pipe. At this time, the lower inclined surface of the baffle on the right fits against the upper inclined surface of the rotating plate to prevent the rotating plate from continuing to rotate. After the left storage area is full, the rotating plate rotates again so that its lower inclined surface fits against the inner wall of the right discharge pipe. At this time, the lower inclined surface of the baffle on the left fits against the upper inclined surface of the rotating plate to prevent the rotating plate from continuing to rotate. After the right storage area is full, the unloading car is moved to the next storage area. The two inclined plates fix the rotating plate on one hand and allow all materials to move onto the rotating plate and be discharged from the discharge port along the rotating plate, thus making full use of the material storage space.

[0014] This invention solves the problem of foreign objects accumulating on the track, preventing the unloading vehicle from moving normally, by setting up a brush and a baffle plate. When the unloading vehicle moves, the brush located in front of the direction of movement pushes away foreign objects to prevent them from obstructing the movement of the unloading vehicle. The baffle plate prevents materials on the conveyor belt from falling into the track below during the transportation process, thus ensuring the normal movement of the unloading vehicle.

[0015] This invention solves the problem of material flying out from the gap between the conveyor belt and the discharge assembly by setting an inclined plate and a pad. The highest point of the inclined plate is located below the upper redirecting roller, and the pad is attached to the conveyor belt. The flying material either falls directly and is finally discharged from the discharge pipe, or it falls on the inclined plate, slides down the inclined plate, and is finally discharged from the discharge pipe, thus preventing material leakage and saving material.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0028] Please see Figure 1-3 This utility model is a heavy-duty mobile unloading device, including a base 1, a discharge component 2 and a diagonal brace 3; two diagonal braces 3 are symmetrically arranged above the base 1, and the discharge component 2 is arranged on one side of the base 1 and the diagonal brace 3. Frames 102 are fixedly connected to both sides of the base 1. A traveling component 104 is rotatably connected inside the frame 102. A longitudinal brace 301 is fixedly connected to the side of the higher end of the diagonal brace 3 near the discharge component 2. Support roller groups 302 are arranged in the middle and the top of the lower end of the diagonal brace 3. A through groove 101 is opened through the side of the base 1 near the discharge component 2. A redirecting roller 4 is rotatably connected inside the through groove 101 and between the two longitudinal braces 301. The traveling wheels of the traveling component 104 are mounted on the track. The rotation of the traveling wheels can drive the entire unloading vehicle to move. The base 1, frame 102 and traveling component 104 provide support for the entire mobile unloading device. When carrying out material conveying and unloading, the conveyor belt is introduced from the front end of the unloading vehicle. Under the support of the two support roller groups 302, it moves from the higher end of the upper redirecting roller 4 to the lower end of the lower redirecting roller 4 and finally leads to the rear of the unloading vehicle. During this process, the material moves with the conveyor belt and enters the discharge component 2. Finally, it falls into the storage area on both sides of the unloading vehicle through the discharge component 2. After the material in the storage area reaches the accumulation threshold, the traveling component 104 rotates to move the unloading vehicle to the next storage area. The setting of the support roller group 302 makes the conveyor belt sink in the middle and tilted at both ends when it moves on the mobile unloading device, so that the material on the conveyor belt is not easy to fly out from both ends. The discharge assembly 2 includes two symmetrically arranged side plates 202. A vertical plate 203 is fixedly connected between the two side plates 202 at a position away from the base 1. A vertical plate 208 is fixedly connected at the lower part of the two side plates 202 at a position close to the base 1. Two baffles 204 are symmetrically fixedly connected at the upper part between the opposite surfaces of the vertical plate 203 and the vertical plate 208. A rotating plate 205 is rotatably connected at the lower part between the opposite surfaces of the vertical plate 203 and the vertical plate 208. The discharge assembly 2 also includes two symmetrically arranged discharge pipes 206. Each discharge pipe 206 is fixedly connected to the side plate 202 above it. The discharge pipe 206 is located below the rotating plate 205. Side plate 202, vertical plate one 203, and vertical plate two 208 constitute the frame 102 of the discharge assembly 2. Rotating the rotating plate 205 causes its lower inclined surface to adhere to the inner wall of the discharge pipe 206 on the left. At this time, the lower inclined surface of the baffle 204 on the right adheres to the upper inclined surface of the rotating plate 205, preventing the rotating plate 205 from continuing to rotate. After reaching its highest point, the material on the conveyor belt will continue to move forward due to inertia and fall into the discharge assembly 2. Under the protection of the two baffles 204, the material will fall onto the upper inclined surface of the rotating plate 205 and, under the action of gravity, move along the upper inclined surface of the rotating plate 205. The material moves downwards and is eventually discharged from the discharge pipe 206 on the left and falls into the storage area on the left side of the unloading vehicle. After the storage area on the left is full, the rotating plate 205 is rotated in the opposite direction so that the lower inclined surface of the rotating plate 205 is in contact with the inner wall of the discharge pipe 206 on the right. At this time, the lower inclined surface of the baffle 204 on the left is in contact with the upper inclined surface of the rotating plate 205. The material entering the discharge assembly 2 moves downwards along the upper inclined surface of the rotating plate 205 under the action of gravity and is discharged from the discharge pipe 206 on the right and falls into the storage area on the right side of the unloading vehicle. After the storage area on the right is full, the unloading vehicle can be moved to the next storage area.

[0029] Among them, such as Figure 3As shown, a motor box 105 is fixedly connected to one side of the base 1 away from the through groove 101. A motor 106 is installed inside the motor box 105. A pulley 109 is rotatably connected to the side of the motor box 105 away from the base 1. The shaft of the output end of the motor 106 extends through the motor box 105 and is connected to the pulley 109 for transmission. A pulley 109 is externally connected to the end of the walking component 104 away from the discharge component 2 and close to the motor 106. A transmission belt 1091 is connected between the two pulleys 109. When motor 106 is started, the shaft at the output end of motor 106 rotates, which drives the pulley 109 connected to the shaft to rotate, thereby driving the transmission belt 1091 and the pulley 109 connected to the traveling component 104 to rotate, thereby driving the traveling component 104 to rotate, thus realizing the movement of the unloading vehicle.

[0030] Among them, such as Figure 4 As shown, three support columns 103 with progressively increasing heights are fixedly connected to both sides of the top of the base 1. The tops of the three support columns 103 on the same side of the base 1 are fixedly connected to a diagonal brace 3. The lower end of the diagonal brace 3 is fixedly connected to the frame 102 away from the discharge assembly 2. The frame 102 and the three support columns 103 provide support for the diagonal brace 3 and the redirecting roller 4.

[0031] Among them, such as Figure 3-5 As shown, the two middle support columns 103 are fixedly connected to a cross brace 107 on the side of their upper part near the discharge assembly 2. The lower support roller group 302 is fixedly connected to the frame 102 away from the discharge assembly 2, and the higher support roller group 302 is fixedly connected to the cross brace 107. The frame 102 and the diagonal brace 3 provide support for the lower support roller group 302, and the diagonal brace 3 and the cross brace 107 provide support for the upper support roller group 302.

[0032] Among them, such as Figure 1 , Figure 4-6 As shown, two support columns 108 are symmetrically fixedly connected at the top of the frame 102 located below the discharge assembly 2, away from the base 1. The support columns 108 are fixedly connected to the side plate 202 above them. The side plate 202 has a groove 2021 on its upper part, and the longitudinal brace 301 is inserted into the groove 2021 for fixation. The support columns 108 and the longitudinal brace 301 provide support for the discharge assembly 2.

[0033] Among them, such as Figure 6-8 As shown, the top of the two side plates 202 are fixedly connected to the top plate 201, and the top of the vertical plate 208 is fixedly connected to the inclined plate 207. The two ends of the inclined plate 207 are fixedly connected to the two side plates 202 respectively, and the top of the inclined plate 207 is provided with a pad strip 2071. The inclined plate 207 is located below the upper redirecting roller 4, and the pad strip 2071 is attached to the surface of the conveyor belt. There is no longer a gap between the discharge component 2 and the conveyor belt, so no material will fly out and material waste will be prevented.

[0034] Among them, such as Figure 6 , Figure 8 As shown, a motor 2051 is fixedly connected to the side of vertical plate 203 away from vertical plate 208. The shaft of the output end of motor 2051 extends through vertical plate 203 and is connected to rotating plate 205 for transmission.

[0035] When it is necessary to rotate the rotating plate 205 in the forward or reverse direction, simply start the motor 2051. The rotating shaft at the output end of the motor 2051 will rotate in the forward or reverse direction, which will drive the rotating plate 205 to rotate in the forward or reverse direction, causing the material to fall into the storage area on the left or right side.

[0036] The working principle of this embodiment is as follows: During material conveying and unloading, the conveyor belt is introduced from the front end of the unloading vehicle. Supported by two support roller groups 302, it winds from the higher end of the upper redirecting roller 4 to the lower end of the lower redirecting roller 4, and finally leads to the rear of the unloading vehicle. During this process, the material moves with the conveyor belt and enters the discharge assembly 2. The inclined plate 207 is located below the upper redirecting roller 4, and the pad strip 2071 is attached to the surface of the conveyor belt. There is no longer a gap between the discharge assembly 2 and the conveyor belt. Material may fly out. To prevent waste, start motor 2051. The output of motor 2051 rotates, driving the rotating plate 205 to rotate. This causes the lower inclined surface of the rotating plate 205 to adhere to the inner wall of the discharge pipe 206 on the left. At this time, the lower inclined surface of the baffle 204 on the right adheres to the upper inclined surface of the rotating plate 205, preventing the rotating plate 205 from continuing to rotate. After reaching the highest point, the material on the conveyor belt will continue to move forward due to inertia and fall into the discharge assembly 2. Under the protection of the two baffles 204, the material will fall... The material moves down the upper slope of the rotating plate 205 under the influence of gravity, eventually exiting through the left discharge pipe 206 and falling into the storage area on the left side of the unloading vehicle. Once the left storage area is full, the motor is restarted, and the output end of motor 2051 rotates in reverse, causing the rotating plate 205 to rotate in reverse. This causes the lower slope of the rotating plate 205 to adhere to the inner wall of the right discharge pipe 206. At this time, the lower slope of the left baffle 204 adheres to the upper slope of the rotating plate 205, and the material enters the discharge assembly. Under the action of gravity, the material 2 moves downward along the upper slope of the rotating plate 205 and is discharged from the discharge pipe 206 on the right side into the storage area on the right side of the unloading vehicle. After the storage area on the right side is full, the motor 106 is started. The shaft at the output end of the motor 106 rotates, which drives the pulley 109 connected to the shaft to rotate, thereby driving the transmission belt 1091 and the pulley 109 connected to the traveling component 104 to rotate, which in turn drives the traveling component 104 to rotate, moving the unloading vehicle to the next unloading area. Specific Implementation Example 2

[0037] Please see Figure 1 Based on the first specific embodiment, the bottom end of the frame 102 is fixedly connected to both ends of the side away from the base 1, and the bottom end of the connecting rod 1021 is fixedly connected to the brush 1022. The inclined surface of the diagonal brace 3 and the top end of the longitudinal brace 301 are jointly fixedly connected to the baffle plate 303.

[0038] The working principle of this embodiment is as follows: when the unloading car moves, the brush 1022 located in front of the unloading car in the direction of movement cleans the foreign objects on the track to prevent the foreign objects from affecting the movement of the unloading car. The setting of the baffle plate 303 ensures that the material on the conveyor belt will not fall onto the track between the two brushes 1022.

[0039] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
