Description

Technical Field

[0001] This invention relates to the technical field of automatic unloading equipment for semi-trailers, specifically to an automatic unloading device for transport semi-trailers. Background Technology

[0002] A semi-trailer is a heavy-duty transport vehicle connected to a semi-trailer head by a towing pin. Semi-trailers are typically used for long-distance transport of large-volume or high-quality goods. The use of semi-trailers can also promote the organization of logistics in my country to a certain extent. When using semi-trailers to transport bulk and scattered goods such as coal, ore, and building materials, the goods can be quickly unloaded through the unloading equipment on the semi-trailer after reaching the destination, which can effectively improve the transportation efficiency of bulk and scattered goods by semi-trailers.

[0003] Among them, the automatic unloading device of semi-trailer is mostly used for bulk ore transportation. During automatic unloading, since the push plate and the side wall of the hopper are in a sliding state, some of the crushed stone in the ore will accumulate at the sliding contact position between the push plate and the hopper during the sliding process of the push plate, resulting in the phenomenon of crushed stone being embedded in the sliding gap. At this time, the crushed stone will increase the friction between the push plate and the inner wall of the hopper, resulting in excessive friction between the push plate and the hopper. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an automatic unloading device for a semi-trailer, including a frame, a truck bed fixedly connected to the top of the frame, a sliding plate slidably connected to the inner wall of the truck bed, a load-bearing rolled plate fixedly connected to the side wall of the sliding plate, and an inclined plate fixedly connected to the side wall of the truck bed, and further including: The limiting mechanism is fixedly connected to the side wall of the sliding plate; The pressure mechanism is slidably connected to the outer wall of the limiting mechanism; The protective mechanism is slidably connected to the top of the sliding plate; The frame is equipped with a winding device, and a motor is fixedly connected to the bottom of the sliding plate. The motor drives the sliding plate to slide along the outer wall of the frame. The end of the load-bearing coil away from the sliding plate is connected to the winding device. When it is necessary to discharge the material inside the truck bed, the sliding plate drives the load-bearing coil to be discharged outward.

[0005] Preferably, the limiting mechanism includes: Auxiliary components are fixedly connected to the top of the frame; A rotating component is fixedly connected to the outer wall of the auxiliary component; When the sliding plate moves laterally, the auxiliary component will force the rotating component to rotate.

[0006] Preferably, the pressure mechanism includes: Push the component to slide it onto the inner wall of the auxiliary component; The cleaning component is slidably connected to the side wall of the sliding plate; In this process, when the auxiliary component drives the rotating component to rotate, the rotating component drives the cleaning component to slide regularly along the outer wall of the sliding plate by pushing the component.

[0007] Preferably, the protective mechanism includes: The shielding component is slidably connected to the top of the sliding plate; The push-out component is rotatably connected to the side wall of the shielding component; As the sliding plate pushes the ore to move, the ore accumulation height will exceed the highest position of the sliding plate. The blocking component will adapt to the height of the ore, and as the ore height continues to increase, the outward pushing component will pop out and push out the excess ore.

[0008] Preferably, the auxiliary components include a slide rail fixedly connected to the top of the frame, a slide frame slidably connected to the top of the slide rail, a rail fixedly connected to the side wall of the slide frame, and a rack fixedly connected to the side wall of the frame. The side wall of the sliding frame is fixedly connected to the side wall of the sliding plate, and the length of the rack is equal to the length of the slide rail and the frame.

[0009] Preferably, the rotating assembly includes a fixed frame fixedly connected to the outer wall of the sliding frame, a gear rotatably connected to the inner wall of the through hole of the fixed frame, a rotating disk fixedly connected to the top of the gear, and a push rod fixedly connected to the top of the rotating disk. The outer wall of the gear meshes with the outer wall of the rack, which means that when the sliding plate moves the fixed frame through the sliding frame, the gear will mesh and rotate along the outer wall of the rack, while simultaneously driving the rotating disk and the push rod to rotate.

[0010] Preferably, the pushing component includes a sliding rod that slides along the inner wall of the sliding connection track, the bottom of the sliding rod having a contact groove, and the top of the sliding rod being fixedly connected to a second pushing rod; The inner wall of the contact groove is slidably connected to the outer wall of the push rod. When the rotating disk drives the push rod to rotate, the push rod will drive the sliding rod to slide along the inner wall of the track.

[0011] Preferably, the cleaning component includes a slid groove 1 formed on both sides of the sliding plate, a push plate slidably connected to the inner wall of the slid groove 1, a push rod 3 fixedly connected to the side wall of the push plate, and a pressure frame fixedly connected to the end of the push rod 3 away from the push plate. Among them, the side wall of push rod two is fixedly connected to the side wall of the pressure frame. When push rod two slides back and forth, push rod two drives push plate to slide synchronously along the inner wall of slide groove one through pressure frame and push rod three.

[0012] Preferably, the shielding component includes a second slide groove formed on the top of the sliding plate, a U-shaped rod slidably connected to the inner wall of the second slide groove, an inclined plate fixedly connected to the top of the U-shaped rod, and a roller rotatably connected to the side wall of the U-shaped rod. As the sliding plate pushes the ore inside the truck bed, the ore is compressed and accumulates. As the height of the accumulation increases, the inclined plate is pushed and drives the U-shaped rod to slide upward along the inner wall of the second chute.

[0013] Preferably, the push-out assembly includes a baffle plate fixedly connected to the side wall of the U-shaped rod, a rotating groove is provided on the inner wall of the baffle plate, a rotating push plate is rotatably connected to the inner wall of the rotating groove, and a spring is fixedly connected to the inner wall of the rotating groove. The end of the spring away from the rotating groove is fixedly connected to the inner wall of the rotating push plate. When the rotating push plate is on the inner wall of the second groove, the spring will be in a compressed state and accumulate potential energy.

[0014] The present invention has the following beneficial effects: (1) In view of the problem that the sliding plate and the truck bed are prone to crushed stone getting stuck at the sliding position, which increases the sliding resistance of the sliding plate, the present invention provides a pressure mechanism inside the equipment. When the sliding plate starts to push the ore outward, the sliding plate drives the fixed frame to move through the sliding frame. The gear will mesh and rotate along the outer wall of the rack, and at the same time drive the rotating disk and the first push rod to rotate. The first push rod will drive the sliding rod to slide back and forth along the inner wall of the track. The sliding rod drives the push plate to slide regularly along the inner wall of the first slide groove through the second push rod, the pressure frame and the third push rod. Through the application of the above components, the push plate slides regularly back and forth at the contact position between the sliding plate and the truck bed during the sliding process. The push plate discharges the crushed stone at the contact position outward, reducing the impact of the crushed stone on the sliding plate. (2) In view of the problem of ore accumulation when the sliding plate pushes the ore, the present invention provides a shielding component inside the equipment. Since the side wall of the ore is in contact with the inner wall of the truck bed, the ore will accumulate on the side wall of the sliding plate when the sliding plate pushes the ore. As the accumulation height increases, the accumulated ore will contact the bottom of the inclined plate and force the inclined plate to slide down along the inner wall of the second chute. Through the above-mentioned inclined plate sliding design, it is effectively ensured that when the ore accumulates, the inclined plate can intercept the ore that is too high, preventing the ore from passing over the sliding plate and reaching the pressure mechanism and protection mechanism, thus affecting the operation between them.

[0015] (3) The present invention utilizes the characteristic of the inclined plate sliding upward due to the accumulation of ore. An outward pushing component is provided inside the equipment. As the height of the inclined plate increases, the highest position of the sliding plate will exceed the lowest position of the rotating groove. At this time, the outer wall of the rotating groove is no longer restricted, the spring releases potential energy, and the rotating groove pushes outward to push out the ore that has accumulated too high. Through the application of the above component, it is prevented that the ore accumulates too high and exceeds the height of both sides of the truck bed, and the ore overflows from both ends of the truck bed. (4) As the sliding plate continues to push out, all the ore is eventually pushed out of the hopper. At this time, rotating the push plate will form a shape like... Figure 11 In the initial state, the sliding plate then moves towards the inclined plate position for a reset process. During the sliding process, the sliding plate will drive the roller to slide synchronously. Eventually, the outer wall of the roller will contact the bottom inclined surface of the inclined plate, and the resulting pressure will force the roller to slide downward. The roller will drive the U-shaped rod to slide downward synchronously, causing the rotating push plate to rotate upward due to the restriction of the outer wall of the sliding plate. Finally, after the U-shaped rod completes its downward slide, the rotating push plate will bend and press tightly against the inner wall of the rotating groove. Through the application of the above components, after the equipment completes autonomous unloading, each component will be in a ready-to-process state, thus accelerating the unloading efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figure 1 - Figure 6 This invention relates to an automatic unloading device for a semi-trailer, comprising a frame 13, a truck bed 14 fixedly connected to the top of the frame 13, a sliding plate 15 slidably connected to the inner wall of the truck bed 14, a load-bearing rolled plate 16 fixedly connected to the side wall of the sliding plate 15, and an inclined plate 17 fixedly connected to the side wall of the truck bed 14, and further comprising: Restriction mechanism 1 is fixedly connected to the side wall of sliding plate 15; Pressure mechanism 2 is slidably connected to the outer wall of limiting mechanism 1; Protective mechanism 3 is slidably connected to the top of sliding plate 15; The frame 13 is equipped with a winding device, and a motor is fixedly connected to the bottom of the sliding plate 15. The motor drives the sliding plate 15 to slide along the outer wall of the frame 13. The end of the load-bearing coil 16 away from the sliding plate 15 is connected to the winding device. When it is necessary to discharge the material inside the truck bed 14, the sliding plate 15 drives the load-bearing coil 16 to discharge it outward.

[0021] Restricted agency 1 includes: Auxiliary component 11 is fixedly connected to the top of the frame 13; Rotating component 12 is fixedly connected to the outer wall of auxiliary component 11; When the sliding plate 15 moves laterally, the auxiliary component 11 will force the rotating component 12 to rotate.

[0022] Pressure mechanism 2 includes: Push component 21, push component 21 is slidably connected to the inner wall of auxiliary component 11; Cleaning component 22 is slidably connected to the side wall of sliding plate 15; When the auxiliary component 11 drives the rotating component 12 to rotate, the rotating component 12 drives the cleaning component 22 to slide regularly along the outer wall of the sliding plate 15 by pushing the component 21.

[0023] Protective mechanism 3 includes: The shielding component 31 is slidably connected to the top of the sliding plate 15; The push-out component 32 is rotatably connected to the side wall of the shielding component 31; As the sliding plate 15 pushes the ore to move, the ore accumulation height will exceed the highest position of the sliding plate 15. The blocking component 31 will adapt to the height of the ore, and as the ore height continues to increase, the outward pushing component 32 will pop out and push out the excess ore.

[0024] Example 2, please refer to Figure 3 - Figure 11 The present invention is an automatic unloading device for a semi-trailer. Based on Example 1, the auxiliary component 11 includes a slide rail 111 fixedly connected to the top of the frame 13, a slide frame 112 slidably connected to the top of the slide rail 111, a track 113 fixedly connected to the side wall of the slide frame 112, and a toothed rod 114 fixedly connected to the side wall of the frame 13. The side wall of the sliding frame 112 is fixedly connected to the side wall of the sliding plate 15, and the length of the toothed rod 114 is equal to the length of the slide rail 111 and the frame 13.

[0025] The rotating assembly 12 includes a fixed frame 121 fixedly connected to the outer wall of the sliding frame 112. A gear 122 is rotatably connected to the inner wall of the through hole of the fixed frame 121. A rotating disk 123 is fixedly connected to the top of the gear 122. A push rod 124 is fixedly connected to the top of the rotating disk 123. The outer wall of gear 122 meshes with the outer wall of rack 114, which means that when sliding plate 15 moves fixed frame 121 via sliding frame 112, gear 122 will mesh and rotate along the outer wall of rack 114, while driving rotating disk 123 and push rod 124 to rotate.

[0026] The pushing component 21 includes a sliding rod 211 on the inner wall of the sliding connection track 113, a contact groove 212 is provided at the bottom of the sliding rod 211, and a pushing rod 213 is fixedly connected to the top of the sliding rod 211; As the sliding plate 15 is continuously pushed out, all the ore is eventually pushed out of the hopper 14. At this time, rotating the push plate 323 will form a shape like... Figure 11 In the state of sliding plate 15, the sliding plate 15 moves to the inclined plate 17 to perform a reset process. During the sliding process, the sliding plate 15 will drive the roller 314 to slide synchronously. Eventually, the outer wall of the roller 314 will contact the bottom inclined surface of the inclined plate 17, and the pressure generated will force the roller 314 to slide downward. The roller 314 will drive the U-shaped rod 312 to slide downward synchronously, so that the rotating push plate 323 is restricted by the outer wall of the sliding plate 15 and rotates upward. Finally, after the U-shaped rod 312 completes its downward slide, the rotating push plate 323 will bend and stick tightly to the inner wall of the rotating groove 322. Through the application of the above components, after the equipment completes autonomous unloading, each component will be in a waiting state, which speeds up the unloading efficiency.

[0027] The cleaning component 22 includes a first groove 221 opened on both sides of the sliding plate 15, a push plate 222 slidably connected to the inner wall of the first groove 221, a third push rod 223 fixedly connected to the side wall of the push plate 222, and a pressure frame 224 fixedly connected to the end of the third push rod 223 away from the push plate 222. To address the issue of stone fragments easily getting stuck at the sliding position between the sliding plate 15 and the hopper 14, increasing the sliding resistance of the sliding plate 15, a pressure mechanism 2 is installed inside the equipment. When the sliding plate 15 begins to push the ore outward, as the sliding plate 15 moves the fixed frame 121 via the sliding frame 112, the gear 122 will mesh and rotate along the outer wall of the toothed rod 114, simultaneously driving the rotating disk 123 and the first push rod 124 to rotate. The first push rod 124 will drive the sliding rod 211 to slide back and forth along the inner wall of the track 113. The sliding rod 211, through the second push rod 213, the pressure frame 224, and the third push rod 223, drives the push plate 222 to slide regularly along the inner wall of the first chute 221. Through the application of the above components, during the sliding process of the sliding plate 15, the push plate 222 slides regularly back and forth at the contact position between the sliding plate 15 and the hopper 14, and the push plate 222 discharges the stone fragments at the contact position outward, reducing the impact of the stone fragments on the sliding plate 15.

[0028] The shielding assembly 31 includes a second slide groove 311 opened on the top of the sliding plate 15, a U-shaped rod 312 slidably connected to the inner wall of the second slide groove 311, an inclined plate 313 fixedly connected to the top of the U-shaped rod 312, and a roller 314 rotatably connected to the side wall of the U-shaped rod 312. To address the issue of ore accumulation when the sliding plate 15 pushes the ore, a shielding component 31 is installed inside the equipment. Because the side wall of the ore is in contact with the inner wall of the hopper 14, the ore accumulates on the side wall of the sliding plate 15 when it pushes the ore. As the accumulation height increases, the accumulated ore will contact the bottom of the inclined plate 313, forcing the inclined plate 313 to slide downwards along the inner wall of the chute 311. Through the above-mentioned design of the inclined plate 313 sliding, it is effectively ensured that when the ore accumulates, the inclined plate 313 can intercept the ore that is too high, preventing the ore from crossing the sliding plate 15 and reaching the pressure mechanism 2 and the protection mechanism 3, thus affecting their operation.

[0029] The push-out assembly 32 includes a baffle plate 321 fixedly connected to the side wall of the U-shaped rod 312. A rotating groove 322 is provided on the inner wall of the baffle plate 321. A rotating push plate 323 is rotatably connected to the inner wall of the rotating groove 322. A spring 324 is fixedly connected to the inner wall of the rotating groove 322. Taking advantage of the upward sliding characteristic of the inclined plate 313 due to the accumulation of ore, an outward pushing component 32 is installed inside the equipment. As the height of the inclined plate 313 increases, the highest position of the sliding plate 15 will exceed the lowest position of the rotating groove 322. At this time, the outer wall of the rotating groove 322 is no longer restricted, the spring 324 releases potential energy, and the rotating groove 322 pushes outward to push out the ore that has accumulated too high. Through the application of the above component, it is prevented that the ore accumulates too high and exceeds the height of both sides of the hopper 14, and the ore overflows from both ends of the hopper 14.

[0030] A specific application of this embodiment is: when it is necessary to discharge the material inside the truck bed 14 outward, the motor inside the sliding plate 15 drives the sliding plate 15 to slide, and at the same time drives the load-bearing roll plate 16 to discharge outward. To address the issue of gravel getting stuck at the sliding position between the sliding plate 15 and the hopper 14, increasing the sliding resistance of the sliding plate 15, a pressure mechanism 2 is installed inside the equipment. When the sliding plate 15 begins to push the ore outward, as the sliding plate 15 moves the fixed frame 121 via the sliding frame 112, the gear 122 will mesh and rotate along the outer wall of the toothed rod 114, simultaneously driving the rotating disk 123 and the first push rod 124 to rotate. The first push rod 124 will drive the sliding rod 211 to slide back and forth along the inner wall of the track 113. The sliding rod 211, through the second push rod 213, the pressure frame 224, and the third push rod 223, drives the push plate 222 to slide regularly along the inner wall of the first chute 221. Through the application of the above components, during the sliding process of the sliding plate 15, the push plate 222 slides regularly back and forth at the contact position between the sliding plate 15 and the hopper 14, and the push plate 222 discharges the gravel at the contact position outward, reducing the impact of the gravel on the sliding plate 15. To address the issue of ore accumulation when the sliding plate 15 pushes the ore, a shielding component 31 is installed inside the equipment. Since the sidewall of the ore contacts the inner wall of the hopper 14, ore accumulates on the sidewall of the sliding plate 15 when it pushes the ore. As the accumulation height increases, the accumulated ore contacts the bottom of the inclined plate 313, forcing the inclined plate 313 to slide downwards along the inner wall of the chute 311. This design of the inclined plate 313 effectively ensures that when ore accumulates, the inclined plate 313 can intercept excessively high ore, preventing it from exceeding the sliding plate 15 and reaching the pressure mechanism 2 and the protective mechanism 3, thus affecting their operation.

[0031] Taking advantage of the characteristic of the inclined plate 313 sliding upwards due to the accumulation of ore, an outward pushing component 32 is provided inside the equipment. As the height of the inclined plate 313 increases, the highest position of the sliding plate 15 will exceed the lowest position of the rotating groove 322. At this time, the outer wall of the rotating groove 322 is no longer restricted, the spring 324 releases potential energy, and the rotating groove 322 pushes outwards to push out the ore that has accumulated too high. Through the application of the above component, it is prevented that the ore accumulates too high and exceeds the height of both sides of the hopper 14, and the ore overflows from both ends of the hopper 14. As the sliding plate 15 continues to push out, eventually all the ore is pushed out of the hopper 14. At this time, rotating the push plate 323 will form a shape like... Figure 11In the state of sliding plate 15, the sliding plate 15 moves to the inclined plate 17 to perform a reset process. During the sliding process, the sliding plate 15 will drive the roller 314 to slide synchronously. Eventually, the outer wall of the roller 314 will contact the bottom inclined surface of the inclined plate 17, and the pressure generated will force the roller 314 to slide downward. The roller 314 will drive the U-shaped rod 312 to slide downward synchronously, so that the rotating push plate 323 is restricted by the outer wall of the sliding plate 15 and rotates upward. Finally, after the U-shaped rod 312 completes its downward slide, the rotating push plate 323 will bend and stick tightly to the inner wall of the rotating groove 322. Through the application of the above components, after the equipment completes autonomous unloading, each component will be in a waiting state, which speeds up the unloading efficiency.
