Description

Technical Field

[0001] This utility model relates to a transport vehicle, specifically a self-cleaning scraper-type dump truck equipped with a scraper for unloading goods. Background Technology

[0002] A scraper-type dump truck is a dump truck with a scraper installed at the bottom of the truck body. The scraper is driven back and forth by a chain or other drive device to unload the cargo.

[0003] In the existing scraper and chain operation, the scraper assembly, composed of the scraper and chain, surrounds the base plate. The part of the scraper assembly located under the base plate is prone to falling under the influence of gravity. The falling scraper assembly is prone to breakage. At the same time, the falling scraper assembly is also prone to lateral deviation while running under the base plate. Utility Model Content

[0004] The main purpose of this utility model is to provide a scraper-type dump truck with guide rods to solve the problem that in the prior art, the scraper assembly at the bottom part of the base plate will fall under the action of gravity during operation and is prone to lateral deviation.

[0005] This utility model provides a scraper-type dump truck with guide rods. The scraper-type dump truck includes a frame and a cargo box on the frame. The cargo box includes side panels and a floor plate. A scraper assembly is disposed on the floor plate, surrounding it. The scraper assembly includes chains on the left and right sides and a scraper between the two chains. The frame includes two longitudinally distributed longitudinal beams. The floor plate is disposed on the upper part of the longitudinal beams; a lower crossbeam is disposed on the lower part of the longitudinal beams. When the scraper assembly is located under the cargo box, it is positioned above the lower crossbeam. Longitudinally distributed guide rods are disposed on the lower crossbeam, and the scraper is located on the upper part of the guide rods.

[0006] Preferably, there are two guide rods, which are located on the left and right sides of the scraper, respectively.

[0007] Preferably, the guide rod is inclined.

[0008] Preferably, the guide rod is cylindrical.

[0009] Preferably, the longitudinal beam is an I-beam, and the lower part of the longitudinal beam is provided with an inwardly extending inner wing plate, with the chain located on the upper part of the inner wing plate.

[0010] Preferably, a top plate is also provided on the upper part of the inner wing plate, and the chain is located on the upper part of the top plate.

[0011] The scraper-type dump truck with guide rod provided by this utility model has the following advantages compared with the prior art:

[0012] Beneficial effects:

[0013] The aforementioned scraper dump truck with guide rods utilizes guide rods installed on the lower crossbeam below the longitudinal beams. This creates a structurally stable support structure under the floor, with no obstructions above the guide rods. During the movement of the scraper assembly to the lower part of the floor, the scraper slides back and forth on the guide rods. The guide rods support the scraper, preventing it from sagging due to excessive weight. Simultaneously, the scraper moves smoothly on the guide rods, resulting in more stable operation of the scraper assembly compared to trucks without guide rods, and reducing the likelihood of lateral deviation.

[0027] Example 1

[0028] This embodiment provides a scraper dump truck with guide rods. The scraper dump truck includes a frame and a cargo box on the frame. The cargo box includes side panels and a floor plate 3. A scraper assembly is disposed around the floor plate 3. The scraper assembly includes chains 2 on the left and right sides and a scraper 1 between the two chains 2. The frame includes two longitudinally distributed longitudinal beams 5. The floor plate 3 is disposed above the longitudinal beams 5. A lower crossbeam 6 is disposed below the longitudinal beams 5. When the scraper assembly is located under the cargo box, it is located above the lower crossbeam 6. Longitudinally distributed guide rods 4 are disposed on the lower crossbeam 6, and the scraper 1 is located above the guide rods 4.

[0029] The aforementioned scraper-type dump truck with guide rods has a scraper assembly where the scraper 1 and chain 2 encircle the bottom plate 3. During unloading, the scraper assembly rotates around the bottom plate 3. The portion of the scraper assembly located on the upper part of the bottom plate 3 scrapes the material backward to achieve unloading, while the portion located on the lower part of the bottom plate 3 moves to the upper part of the guide rod 4 and is supported by the guide rod 4, thereby improving the stability of the scraper 1 during operation. It should be noted that, in order to improve the strength of the frame, an upper crossbeam can also be installed on the upper part of the longitudinal beams 5, and the bottom plate 3 of the truck body is located on the upper crossbeam.

[0030] Specifically, in this embodiment, in order to provide more stable support, there are two guide rods 4, which are located on the left and right sides of the scraper 1, respectively. That is, the two guide rods 4 support the left and right sides of the scraper 1 respectively, providing more stable support to the scraper 1 from two points.

[0031] Specifically, when the guide rod 4 is set parallel to the longitudinal beam 5, the scraper 1 only rubs against the guide rod 4 at one point. This design will cause excessive wear at the connection between the scraper 1 and the guide rod 4. In order to reduce the concentrated wear of the scraper 1, the guide rod 4 is set at an angle. When the scraper 1 runs on the guide rod 4, due to the angled setting of the guide rod 4, the guide rod 4 contacts different positions on the scraper 1, thereby causing different positions of the scraper 1 to wear separately, thus avoiding the occurrence of concentrated wear.

[0032] Specifically, in this embodiment, the guide rod 4 is cylindrical. This design reduces the contact area between the guide rod 4 and the scraper 1, thereby reducing the vibration of the scraper 1.

[0033] Specifically, in this embodiment, the longitudinal beam 5 is an I-beam, and the lower part of the longitudinal beam 5 is provided with an inwardly extending inner wing plate 8. The chain 2 is located on the upper part of the inner wing plate 8, and the chain 2 is supported by the inner wing plate 8 to improve the stability of the scraper assembly operation.

[0034] More specifically, in order to avoid excessive wear of the inner wing plate 8 by the chain 2, and considering that the height of the chain 2 and the height of the inner wing plate 8 are inconsistent in some positions, and finally in order to provide better support for the chain 2, a top plate 7 is also provided on the upper part of the inner wing plate 8, and the chain 2 is located on the top plate 7. In this embodiment, the chain 2 can also be supported by the top plate 7.

[0035] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model and should be protected by the present utility model.
