Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand and gravel transportation technology, specifically to a sand and gravel transportation device that prevents spillage. Background Technology
[0002] The reference patent title is: A Sand and Gravel Conveying Device (Authorization Announcement No.: CN218707447U, Authorization Announcement Date: 2023.03.24). It includes two support frames, with a U-shaped slide rail fixedly connected to the top of both support frames. When this conveying device loads material into a dump truck, a servo motor rotates, causing a threaded shaft to rotate. The rotation of the threaded shaft drives a threaded block to move, which in turn moves a sliding plate and a housing. The rotation of the threaded shaft, through two bevel gears, drives one of the threaded rods to rotate. This threaded rod, through a transmission belt and two transmission wheels, drives the other threaded rod to rotate. The rotation of the two threaded rods causes a movable block and a rotating rod to move, causing the housing to move towards the support frame while the rotating rod moves downwards. This gradually shortens the portion of the conveyor belt in contact with the sand and gravel, enabling the housing to move while loading sand and gravel into the dump truck, thus ensuring uniform loading and preventing sand and gravel accumulation.
[0003] Based on the aforementioned document: In the construction and infrastructure industry, sand and gravel are important basic materials, and their transportation is crucial. Existing sand and gravel transportation devices have many drawbacks in practical applications, with frequent spillage problems. Traditional transportation devices are mostly open structures, or although they have simple covers, they cannot cope with complex road conditions and changes in driving status. When vehicles bump, turn, accelerate, or decelerate, sand and gravel are very likely to fall from the edges of the transportation device. This not only wastes sand and gravel resources and increases transportation costs, but also causes serious pollution to the road environment, affects the safety of other vehicles and pedestrians, and increases the burden of road cleaning work. Therefore, this utility model provides a spill-proof sand and gravel transportation device. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4This utility model provides a technical solution:
[0024] A spill-proof sand and gravel transport device includes a transport vehicle body 1 and a discharge hopper 2. A buffer mechanism 3 is provided on the top of the transport vehicle body 1, and a spill-proof mechanism 4 is provided on the top of the discharge hopper 2. The spill-proof mechanism 4 includes:
[0025] The anti-spillage component 41 includes a fixed cover plate 411 installed on the top of the discharge hopper 2. A sliding rod 412 is slidably connected inside the fixed cover plate 411. A sliding block 413 is fixedly connected to one end of the sliding rod 412. A movable cover plate 414 is fixedly connected to the other end of the sliding rod 412. The surface of the movable cover plate 414 is slidably connected to the inner surface of the fixed cover plate 411. A limiting block 415 is fixedly connected to one side of the movable cover plate 414. A limiting groove is formed at the bottom of the limiting block 415.
[0026] The drive assembly 42 is located on one side of the transport vehicle body 1 and is used to drive the movable cover plate 414 to slide.
[0027] The limiting component 43 is located on the other side of the transport vehicle body 1 and is used to limit the movement of the cover plate 414.
[0028] A door is installed on the right side of the hopper 2 for easy unloading.
[0029] A groove is provided on one side of the fixed cover plate 411 for the sliding block 413 to slide;
[0030] The bottom of the movable cover plate 414 is in contact with the top of the discharge hopper 2.
[0031] In this embodiment, the drive assembly 42 includes a drive motor 421 installed on one side of the transport vehicle body 1. One end of the output shaft of the drive motor 421 is fixedly connected to a drive screw 422 via a coupling. The surface of the drive screw 422 is threadedly connected to the inside of the sliding block 413.
[0032] The drive motor 421 is a three-phase asynchronous motor and is connected to an external circuit via wires;
[0033] One end of the drive screw 422 is rotatably connected to a fixed block, which is fixedly connected to one side of the transport vehicle body 1.
[0034] In this embodiment, the limiting component 43 includes a limiting plate 431 installed on the other side of the transport vehicle body 1. A limiting spring 432 is fixedly connected to the bottom of the inner cavity of the limiting plate 431. A limiting rod 433 is fixedly connected to one end of the limiting spring 432. The surface of the limiting rod 433 is slidably connected to the inside of the limiting plate 431. The top end of the limiting rod 433 is engaged with the inner surface of the limiting groove.
[0035] Under the influence of the elasticity of the limiting spring 432, the top of the limiting rod 433 will always remain locked and fixed to the inner surface of the limiting groove.
[0036] In this embodiment, a connecting plate 5 is fixedly connected to one side of the limiting rod 433, and the surface of the connecting plate 5 is slidably connected to the inside of the limiting plate 431.
[0037] The connecting plate 5 is used to connect the limiting rods 433 on both sides.
[0038] By incorporating an anti-spillage mechanism 4, the position of the movable cover plate 414 can be flexibly adjusted under the drive of the drive motor 421. The movable cover plate 414 and the fixed cover plate 411 can seal the feed inlet at the top of the discharge hopper 2. By incorporating a limit component 43, the movable cover plate 414 can be kept stable in the closed state, thereby preventing the sand and gravel inside the discharge hopper 2 from spilling during transportation and improving the quality of sand and gravel transportation.
[0039] In this embodiment, the buffer mechanism 3 includes an equipment box 31 installed on the top of the transport vehicle body 1. A buffer plate 32 is slidably connected to the inner wall of the equipment box 31. A support column 33 is fixedly connected to the top of the buffer plate 32. The surface of the support column 33 is slidably connected to the inside of the equipment box 31. The top end of the support column 33 is fixedly connected to the bottom of the discharge hopper 2. A buffer spring 34 is sleeved on the surface of the support column 33. The top end of the buffer spring 34 is fixedly connected to the bottom of the discharge hopper 2. The bottom end of the buffer spring 34 is fixedly connected to the top of the equipment box 31. A damping component 35 is provided at the bottom of the buffer plate 32.
[0040] In this embodiment, the damping assembly 35 includes a rotating rod 351 rotatably mounted on the bottom of the buffer plate 32. One end of the rotating rod 351 is rotatably connected to a moving block 352. A moving rod 353 is slidably connected inside the moving block 352. Both ends of the moving rod 353 are fixedly connected to the bottom of the inner cavity of the equipment box 31 through a fixing block. A horizontal plate 354 is fixedly connected to the inner side of the moving block 352. A damper 355 is fixedly connected to one side of the horizontal plate 354. The surface of the damper 355 is fixedly connected to the bottom of the inner cavity of the equipment box 31.
[0041] A damper 355, also known as a damping device, is a device that increases damping, with the purpose of rapidly attenuating vibrations caused by impacts.
[0042] By incorporating a buffer mechanism 3, multiple sets of buffer springs 34 and dampers 355 are used to reduce and absorb the transmission of vibration, thereby ensuring the stability of the discharge hopper 2 during the conveying process and preventing sand and gravel spillage.
[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0044] During operation, sand and gravel are first filled into the hopper 2 through the feed inlet at the top. After filling, the drive motor 421 is started to drive the drive screw 422 to rotate. The rotation of the drive screw 422 causes the sliding block 413 to slide in the groove opened on one side of the fixed cover plate 411. The sliding of the sliding block 413 will drive the sliding rod 412 and the moving cover plate 414 to slide synchronously. During this process, the sliding of the moving cover plate 414 will drive the limiting block 415 to slide synchronously. 15 will slide to one side of the transport vehicle body 1 and contact the top of the limiting rod 433, thereby squeezing the limiting rod 433, causing the limiting rod 433 and the connecting plate 5 to slide downward synchronously. The limiting rod 433 and the connecting plate 5 slide inside the limiting plate 431, thereby compressing the limiting spring 432. As the moving cover plate 414 and the limiting block 415 continue to slide, when the moving cover plate 414 completely closes the feed inlet, the top of the limiting rod 433 is also affected by the elasticity of the limiting spring 432. The lower limit groove is locked in place, and the feed inlet is closed by the movable cover plate 414 to prevent the sand and gravel inside the discharge hopper 2 from spilling during transportation. During transportation, the vehicle body often bumps due to road conditions, causing the discharge hopper 2 to vibrate up and down. At this time, the discharge hopper 2 will compress the buffer spring 34, which will buffer the vibration force generated by the bumps. The support column 33 and the buffer plate 32 will slide inside the equipment box 31, so that one end of the rotating rod 351 rotates at the bottom of the buffer plate 32, and the other end of the rotating rod 351 rotates on one side of the moving block 352, so that the moving block 352 slides on the surface of the moving rod 353. The sliding of the moving block 352 will drive the cross plate 354 to move synchronously, thereby compressing the dampers 355 on both sides. The dampers 355 can reduce and absorb the transmission of vibration, thereby ensuring the stability of the discharge hopper 2 during the conveying process and preventing the sand and gravel from spilling.
