Description

Technical Field

[0001] The present invention relates to the technical field of unloading, and more particularly to a tipping unloading device for an unloading vehicle. Background Art

[0002] In the field of material transportation, bulk materials are transported and unloaded using unloading trucks, which are usually equipped with a tiltable or flippable hopper so that the material can be unloaded after reaching the destination;

[0003] During the unloading process, the hydraulic system is generally operated to raise and flip the hopper, so that the material is discharged from the rear of the hopper by gravity. Due to the high packing density of the material in the hopper, some of the material in contact with the inner wall of the hopper is easily adhered to the inner wall of the hopper, which causes this part of the material to be retained in the hopper and unable to be discharged by itself. Usually, the hydraulic system is used to operate the hopper to flip and shake it up and down repeatedly. This operation method can cause some residual material to be discharged, but the remaining severely adhered materials still cannot be smoothly separated from the inner wall of the hopper, resulting in incomplete unloading. Summary of the Invention

[0004] In order to overcome the above technical problems, the present invention proposes a tipping unloading device for an unloading vehicle.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A moving unit is provided above the hopper and includes a driving screw rotatably mounted on both sides of the hopper and a moving frame threadedly connected to the driving screw;

[0008] The scraper unit includes a scraper frame movable relative to the movable frame, the scraper frame is provided with a scraper blade adapted to the inner wall of the hopper; energy storage members are symmetrically provided on both sides of the scraper frame;

[0009] When the moving frame moves along the hopper, the scraper frame is periodically stored and released through the energy storage member, so that the scraper frame periodically impacts one side of the moving frame to drive the scraper blade to remove the material adhering to the inner wall of the hopper.

[0010] As a further solution of the present invention: the scraper unit also includes two groups of sliding rods symmetrically fixed on the movable frame, the scraper frame is slidably sleeved on the corresponding sliding rods on both sides, a limiting plate is provided at the end of the sliding rod away from the movable frame, a thrust spring is provided between the limiting plate and the scraper frame, and the thrust spring is movably sleeved on the corresponding sliding rod.

[0012] As a further solution of the present invention: the blocking member includes a blocking block fixed on the hopper, and a wedge-shaped surface adapted to the shifting rod is provided on a side of the blocking block facing the hopper opening.

[0013] As a further solution of the present invention: a flip block is rotatably mounted on the first sliding block, and the shifting rod is fixed on the flip block.

[0014] As a further solution of the present invention: it also includes an opening and closing unit, which includes a sealing plate rotatably connected to the scraper frame, and a supporting plate is provided on the side of the sealing plate facing the scraper frame.

[0015] As a further solution of the present invention: the support plate member includes a groove formed on the sealing plate, and a support rod is rotatably mounted in the groove.

[0016] As a further solution of the present invention: the support rod and the groove are both provided with magnetic pieces that adapt to each other;

[0017] When the support rod is flipped over and stored in the groove, the two sets of magnetic plates are attracted together.

[0018] As a further solution of the present invention: it also includes a vibrating unit, which includes a second slot symmetrically opened on the movable frame, a pulley is rotatably installed on one side of the second slot, and a second guide rod is horizontally fixed on the other side of the second slot, a second slider is slidably sleeved on the second guide rod, and a second spring is arranged between the end of the second guide rod away from the pulley and the second slider; a cable is wound around the pulley, one end of the cable is connected to the second slider, and the other end of the cable is connected to the vibrating hammer; a linkage part for driving the second slider is also arranged in the second slot.

[0019] As a further solution of the present invention: the linkage member includes a first connecting rod rotatably installed on one side of the second slot and a second connecting rod rotatably installed on the second slider, and a roller is provided at one end of the second connecting rod hinged to the first connecting rod, and the roller is in rolling contact with the scraper frame.

[0020] Beneficial effects of the present invention:

[0021] The scraper rack periodically stores and releases energy, effectively scraping away materials adhering to the inner wall of the hopper, ensuring smooth separation of the materials from the inner wall of the hopper, thereby improving unloading efficiency. The scraper rack periodically stores and releases energy using energy storage components, reducing the retention of materials on the inner wall of the hopper, avoiding material residue, and ensuring thorough unloading.

[0022] An opening and closing unit is provided. When the sealing plate is opened, when the sealing plate periodically collides with the scraper frame under the action of inertia, the end of the support rod will periodically contact the scraper frame, thereby using the support rod to apply impact force to the scraper frame, thereby achieving a secondary impact effect on the scraper frame;

[0023] A vibrating unit is provided. When the scraper frame impacts one side of the movable frame, the scraper frame drives the second slider to slide along the second guide rod toward the end away from the pulley through the linkage, thereby pulling the lower end of the cable to move upward, and then lifting the vibrating hammer to a certain height. Then, when the scraper frame moves away from the movable frame again, the vibrating hammer falls freely under the action of gravity, thereby hitting the bottom surface of the hopper to vibrate the residual material scraped from the hopper and prompt the material to be discharged from the hopper.

[0040] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0041] See also Figure 1 and Figure 2 The present invention discloses a dump truck unloading device, which is applied to a hopper 110 of a dump truck 100 and includes a moving unit 200 and a scraping unit 300;

[0042] See also Figure 3, the moving unit 200 is arranged above the hopper 110, and includes a driving screw 210 rotatably installed on both sides of the hopper 110 and a moving frame 220 threadedly connected to the driving screw 210; the scraper unit 300 includes a scraper frame 320 that can move relative to the moving frame 220, and the scraper frame 320 is provided with a scraper blade 350 adapted to the inner wall of the hopper 110; energy storage members 360 are symmetrically provided on both sides of the scraper frame 320; in the process of the moving frame 220 moving along the hopper 110, the scraper frame 320 is periodically stored and released by the energy storage member 360, so that the scraper frame 320 periodically impacts one side of the moving frame 220, and uses the impact energy to drive the scraper blade 350 to scrape off the material adhering to the inner wall of the hopper 110;

[0043] Specifically, during the overturning unloading process, the hopper 110 is first lifted up to cause it to overturn, and most of the material is discharged outward along the tilted overturned hopper 110, and a small part of the material adheres to the inner wall of the hopper 110; the driving motor (not shown in the figure) provided on the hopper 110 drives the driving screws 210 on both sides of the hopper 110 to rotate synchronously, thereby driving the moving frame 220 to move along the hopper 110 from one side of the hopper 110 discharge port to the other side, and when the moving frame 220 moves During the process, the scraper frame 320 will temporarily remain stationary under the action of the energy storage member 360, so that the distance between the scraper frame 320 and the movable frame 220 gradually increases. At the same time, the energy storage member 360 stores energy in the scraper frame 320. When the stored energy reaches a certain level, the scraper frame 320 releases the stored energy, thereby rapidly impacting one side of the scraper frame 320, thereby driving the scraper blade 350 to scrape off the material adhered to the inner wall of the hopper 110, so that the adhered material can be smoothly separated from the inner wall of the hopper 110.

[0044] It should be noted that the core of the present invention is that through the periodic energy storage and release of the scraper frame 320, the material adhering to the inner wall of the hopper 110 can be effectively scraped off, ensuring that the material can be smoothly separated from the inner wall of the hopper 110, thereby improving the unloading efficiency; using the energy storage part 360 to periodically store energy and release the scraper frame 320 can reduce the retention of material on the inner wall of the hopper 110, avoid material residue, and ensure the thoroughness of unloading.

[0045] In one embodiment, see Figure 6 The scraper unit 300 further includes two sets of slide bars 310 symmetrically fixed on the mobile frame 220. Both sides of the scraper frame 320 are slidably sleeved on the corresponding slide bars 310. A limit plate 330 is provided at one end of the slide bar 310 away from the mobile frame 220. A thrust spring 340 is provided between the limit plate 330 and the scraper frame 320. The thrust spring 340 is movably sleeved on the corresponding slide bar 310.

[0046] Specifically, when the movable frame 220 is driven by the driving screw 210 to move along the hopper 110, the scraper frame 320 temporarily stays at a certain position of the hopper 110 under the action of the energy storage member 360, thereby causing the scraper frame 320 to gradually move away from the movable frame 220. The scraper frame 320 also slides along the sliding rod 310 toward the end away from the movable frame 220, thereby driving the thrust spring 340 to compress and store energy.

[0047] When the scraper frame 320 reaches a certain distance from the movable frame 220, the energy storage member 360 releases the scraper frame 320, and the scraper frame 320 pops out along the slide bar 310 toward the side of the movable frame 220 under the elastic force of the thrust spring 340, and simultaneously drives the scraper blade 350 to produce a rapid impact toward the side of the movable frame 220, thereby removing the stubborn materials on the inner wall of the hopper 110.

[0048] Further, see Figure 3 and Figure 4 The energy storage member 360 includes a first notch 361 formed on the scraper frame 320, a first guide rod 362 vertically fixed in the first notch 361, a first slider 363 slidably mounted on the first guide rod 362, and a lever 366 mounted on the first slider 363. A first spring 364 is provided between the top surface of the first notch 361 and the first slider 363, and the first spring 364 is movably mounted on the first guide rod 362. A plurality of blocking members adapted to the lever 366 are also equidistantly provided on both sides of the hopper 110.

[0049] Specifically, during the forward movement of the movable frame 220, the levers 366 on both sides of the scraper frame 320 will contact one of the groups of blocking members. The blocking members will limit the forward movement of the scraper frame 320 and at the same time drive the thrust spring 340 to gradually compress and store energy until the energy accumulated in the thrust spring 340 can overcome the limiting effect of the blocking members on the lever 366, thereby pushing the first slider 363 to move upward along the first guide rod 362 until the lever 366 disengages from the group of blocking members to release the limit on the scraper frame 320. The scraper frame 320 can then pop out toward the side of the movable frame 220 under the elastic force of the thrust spring 340 to achieve scraping of residual material.

[0050] See also Figure 4 The blocking member includes a block 367 fixed to the hopper 110, and a wedge-shaped surface 368 adapted to the shift rod 366 is provided on the side of the block 367 facing the opening of the hopper 110;

[0051] Specifically, see Figure 5When the push spring 340 is gradually compressed and accumulates energy, it can apply a horizontal thrust to the scraper frame 320 toward the movable frame 220, so that the push rod 366 on the scraper frame 320 is subjected to the force F0 applied by the stop block 367 perpendicular to the wedge surface 368. The force F0 can be decomposed into a vertical component F1 and a horizontal component F2. The greater the compression degree of the push spring 340, the greater the force F0 and the vertical component F1. When the vertical component F1 can overcome the elastic force of the first spring 364 and the friction force between the first slider 363 and the first guide rod 362, the first slider 363 can be driven to slide upward along the first guide rod 362 until the push rod 366 completely reaches above the stop block 367. At this time, the stop block 367 no longer restricts the stroke of the push rod 366, and the scraper frame 320 can pop out under the elastic force of the push spring 340.

[0052] It should be noted that, when the thrust spring 340 is compressed more, the force F0 is greater, and the horizontal component force F2 is also greater, that is, the friction resistance between the first slider 363 and the first guide rod 362 is also greater (friction resistance is related to the friction coefficient and the normal pressure). Therefore, in order to enable the shift rod 366 to smoothly disengage from the block 367, the friction coefficient between the first slider 363 and the first guide rod 362 can be reduced as much as possible, that is, the first slider 363 and the first guide rod 362 are adapted with relatively smooth materials to reduce the friction resistance between the two as much as possible.

[0053] For further information, see Figure 4 , considering that after the residual materials in the entire hopper 110 are completely removed, the moving unit 200 and the scraping unit 300 need to be reversed and reset to the discharge port of the hopper 110. During the reset process, in order to prevent the block 367 from interfering with the shifting rod 366, a flip block 365 is rotatably mounted on the first slider 363, and the shifting rod 366 is fixed to the flip block 365;

[0054] During the scraping process, the flip block 365 is rotated outward to make the lever 366 rotate out of the first slot 361 to a horizontal state. At this time, the lever 366 can just come into contact with the wedge surface 368 on the stop block 367. During the resetting process, the flip block 365 is rotated inward to make the lever 366 rotate upward into the first slot 361 for storage, thereby avoiding the interference of the stop block 367 on the lever 366, so that the movable frame 220 and the scraping frame 320 can be smoothly moved and reset.

[0055] In yet another embodiment, see Figure 6 and Figure 8 , further comprising an opening and closing unit 400, the opening and closing unit 400 comprising a sealing plate 410 rotatably connected to the scraper frame 320, and a supporting plate member 420 being provided on a side of the sealing plate 410 facing the scraper frame 320;

[0056] During the loading and transfer process, the scraper frame 320 is located at the discharge port of the hopper 110, and the sealing plate 410 is always in contact with the scraper frame 320, thereby isolating the scraper frame 320 with the sealing plate 410. At this time, the sealing plate 410 has the function of a gate, thereby preventing the material loaded in the hopper 110 from accidentally overflowing;

[0057] During the unloading process, the sealing plate 410 is flipped upward relative to the scraper frame 320 and opened. At the same time, the sealing plate 410 is supported by the supporting plate 420 so that an opening with a certain angle is formed between the sealing plate 410 and the scraper frame 320. The material in the hopper 110 can be discharged from the opening between the scraper frame 320 and the sealing plate 410.

[0058] It is worth noting that during the unloading process, when the scraper frame 320 periodically pops out and impacts the side of the movable frame 220, the sealing plate 410 will first flip upward toward the side away from the scraper frame 320 under the action of inertia, and then flip downward again and collide with the scraper frame 320. In this process, the collision between the sealing plate 410 and the scraper frame 320 can be used to produce an additional impact effect on the scraper frame 320, thereby improving the scraping effect of the scraper blade 350 on the scraper frame 320 on the material adhering to the inner wall of the hopper 110.

[0059] Accordingly, see Figure 8 and Figure 9 The support plate member 420 includes a groove 421 formed on the sealing plate 410, and a support rod 422 is rotatably mounted in the groove 421;

[0060] When the sealing plate 410 and the scraper frame 320 need to be closed, the support rod 422 is stored in the groove 421. At this time, the sealing plate 410 can fit with the scraper frame 320 to achieve blocking of the scraper frame 320. When unloading is required, the support rod 422 is rotated outward from the groove 421, so that the support rod 422 is flipped to a tilted downward posture. At this time, the support rod 422 maintains this angle unchanged under the action of the limit at the bottom of the groove 421. The end of the support rod 422 away from the sealing plate 410 abuts against the scraper frame 320, so that the sealing plate 410 is supported by the support rod 422 to keep the sealing plate 410 in the open state.

[0061] It should be noted that when the closing plate 410 is opened, when the closing plate 410 periodically collides with the scraper frame 320 under the action of inertia, the end of the support rod 422 will periodically contact the scraper frame 320, thereby utilizing the support rod 422 to apply impact force to the scraper frame 320 to achieve a secondary impact effect on the scraper frame 320.

[0062] See also Figure 9In order to facilitate the storage and deployment of the support rod 422, the support rod 422 and the groove 421 are provided with mutually compatible magnetic pieces 423; when the support rod 422 is flipped and stored in the groove 421, the two sets of magnetic pieces 423 are just attracted together, thereby preventing the support rod 422 from accidentally rotating out and affecting the sealing effect of the sealing plate 410; in addition, in order to prevent the sealing plate 410 from being accidentally opened, a locking structure can be provided between the sealing plate 410 and the scraper frame 320.

[0063] In further embodiments, see Figure 6 、 Figure 7 and Figure 8 In order to facilitate the smooth discharge of scraped residual materials from the hopper 110, a vibrating unit 500 is also included. The vibrating unit 500 includes a second notch 510 symmetrically opened on the movable frame 220. A pulley 520 is rotatably mounted on one side of the second notch 510, and a second guide rod 530 is horizontally fixed on the other side of the second notch 510. A second slider 540 is slidably sleeved on the second guide rod 530, and a second spring 550 is provided between the end of the second guide rod 530 away from the pulley 520 and the second slider 540; a cable 560 is wound around the pulley 520, one end of the cable 560 is connected to the second slider 540, and the other end of the cable 560 is connected to a vibrating hammer 570; a linkage member for driving the second slider 540 is also provided in the second notch 510;

[0064] Specifically, in the initial state, due to the elastic force of the second spring 550, the second slider 540 is always located at the end of the second guide rod 530 close to the pulley 520. At this time, the vibrating hammer 570 at the lower end of the cable 560 is in contact with the inner bottom surface of the hopper 110.

[0065] When the scraper frame 320 impacts one side of the movable frame 220, the scraper frame 320 drives the second slider 540 to slide along the second guide rod 530 toward the end away from the pulley 520 through the linkage, thereby pulling the lower end of the cable 560 upward, and then lifting the vibrating hammer 570 to a certain height. Then, when the scraper frame 320 moves away from the movable frame 220 again, the vibrating hammer 570 falls freely under the action of gravity, thereby hitting the bottom surface of the hopper 110 to vibrate the residual material scraped off from the hopper 110, prompting the material to be discharged from the hopper 110.

[0066] It should be noted that the vibrating hammer 570 falls and hits the hopper 110 after the scraper frame 320 generates an impact motion. That is to say, the adhering materials on the inner wall of the hopper 110 are first scraped off by the scraper blade 350 on the scraper frame 320, and then the vibrating hammer 570 is used to hit the hopper 110 to promote the discharge of materials. The residual materials in the hopper 110 can be completely discharged in batches, thereby improving the orderliness of material discharge and avoiding the accumulation of materials that affects the smoothness of unloading.

[0067] Further, see Figure 7 The linkage member includes a first connecting rod 580 rotatably mounted on one side of the second notch 510 and a second connecting rod 590 rotatably mounted on the second slider 540. A roller 591 is provided at one end of the second connecting rod 590 hinged to the first connecting rod 580. The roller 591 is in rolling contact with the scraper frame 320.

[0068] Specifically, under the elastic force of the second spring 550, the first connecting rod 580 and the second connecting rod 590 pop out toward the scraper frame 320, so that the roller 591 is always in rolling contact with the scraper frame 320;

[0069] When the scraper frame 320 impacts toward the moving frame 220, it squeezes the first connecting rod 580 and the second connecting rod 590, causing the first connecting rod 580 and the second connecting rod 590 to retract into the second notch 510, thereby driving the second slider 540 to slide toward the side away from the pulley 520, thereby pulling the vibrating hammer 570 at the lower end of the cable 560 upward;

[0070] When the scraper frame 320 moves away from the movable frame 220 again under the action of the energy storage member 360, the second slider 540 can slide back to its original position under the elastic force of the second spring 550, and the first connecting rod 580 and the second connecting rod 590 can synchronously extend out of the second slot 510, and the vibrating hammer 570 can fall freely under the action of gravity to achieve impact on the hopper 110 and promote material discharge.

[0071] The above describes the specific implementation of this embodiment, but this embodiment is not limited to the above specific implementation. The above specific implementation is merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
