Description

Technical Field

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

[0002] Scraper dump trucks are dump trucks with scrapers installed at the bottom of the cargo box. The scrapers are driven back and forth by a chain or other drive device to unload the cargo. Examples include the bulk grain transport semi-trailer with product number GB3390X3306 and the bulk grain transport semi-trailer with product number GB7390V4303.

[0003] Existing scraper dump trucks have a cargo box that narrows from top to bottom, with a scraper assembly installed at the bottom of the cargo box. The scraper assembly includes scrapers that are horizontally arranged on the bottom plate of the cargo box and chains, ropes or other driving devices on both sides of the scrapers to drive their movement.

[0004] However, when the cargo is heavy, the scraper's movement resistance is greater; at the same time, in order to facilitate the installation of the scraper assembly, the lower part of the carriage is narrower, and the difference in width between the upper and lower parts of the carriage is large. This not only affects the volume of the carriage, but also leads to poor carriage stability. Utility Model Content

[0005] The main purpose of this utility model is to provide a scraper dump truck to solve the problems of high scraper movement resistance and large differences in the vertical width of the truck body, which lead to poor stability of the truck body during the use of existing scraper dump trucks.

[0006] This utility model provides a scraper dump truck, including a truck body, which includes side panels and a bottom plate. A scraper assembly is provided on the bottom plate, and the scraper assembly includes chains on the left and right sides and a scraper between the two chains. At least two scraper assemblies are provided, and each scraper assembly is arranged parallel and longitudinally on the bottom plate.

[0007] Preferably, the base plate is provided with longitudinally raised ridges, and the scraper assembly is disposed on the base plate between the raised ridges or on the base plate between the raised ridges and the side plate.

[0008] Preferably, the lower part of the side plate is provided with a first U-shaped groove facing the middle of the scraper, and the chain of the scraper assembly near the side plate is located in the first U-shaped groove.

[0009] Preferably, the lower sides of the raised ridge are provided with second U-shaped grooves facing the scraper, and the chain in the scraper assembly near the raised ridge is located in the second U-shaped grooves.

[0010] More preferably, the upper cross section of the protruding ridge is triangular.

[0011] Preferably, the scraper assembly has a first U-shaped groove on both sides, a raised ridge on the bottom plate, and a second U-shaped groove on the raised ridge, with the first or second U-shaped groove tapering off on the side closest to the scraper.

[0012] Preferably, the scraper assembly has two parts, and a raised ridge is provided on the base plate.

[0013] Preferably, the scraper assembly has three parts, and the base plate is provided with two raised ridges.

[0014] Preferably, the side plate is vertically arranged.

[0015] The scraper dump truck provided by this utility model has the following advantages compared with the prior art:

[0016] The aforementioned scraper dump truck has at least two scraper assemblies, meaning at least two scraper assemblies are arranged parallel and longitudinally on the floor of the truck body. This arrangement reduces the width of the scraper assemblies, preventing excessive resistance and damage from excessive stress. Furthermore, by using at least two scraper assemblies, the floor of the truck body can accommodate at least two of them. Therefore, the width of the truck body floor is no longer limited by the width of a single scraper assembly during truck body design. This increases the width of the truck body floor, i.e., the lower part of the truck body, preventing the lower part from being designed to be significantly narrower than the upper part, thus improving the stability of the truck body.

[0031] Example 1

[0032] This embodiment provides a scraper dump truck, including a truck body, which includes side panels 1 and a bottom plate 3. A scraper assembly is provided on the bottom plate 3. The scraper assembly includes chains 5 on the left and right sides and a scraper 4 between the two chains 5. At least two scraper assemblies are provided, and each scraper assembly is arranged parallel and longitudinally on the bottom plate 3.

[0033] When unloading is required, the scraper components of the above-mentioned scraper dump truck can move backward together or separately. When the scraper components move backward, the scraper 4 of the scraper components will drive the material in the truck body backward to achieve the unloading effect. At the same time, the scraper 4 will stick to the bottom plate 3 to scrape off the material on the bottom plate 3 and push it to the rear, thereby achieving unloading. Conventional scraper dump trucks only have one scraper assembly on the floor 3 of the truck body. However, in this embodiment, at least two scraper assemblies are provided. This arrangement allows each scraper assembly to share the resistance of scraping the material, reducing the movement resistance of each scraper assembly and the impact of the material on the scraper assembly. It also reduces the width of the scraper assembly. Furthermore, by providing at least two scraper assemblies, the floor 3 of the truck body can be covered with at least two scraper assemblies. Therefore, the width of the floor 3 is no longer affected by the width of a single scraper assembly during the truck body design. This increases the width of the floor 3, i.e., the lower part of the truck body, preventing the lower part of the truck body from being designed with a width significantly lower than the upper part, thus improving the stability of the truck body. Finally, the scraper assemblies can be configured to move synchronously or separately. When the scraper assemblies move separately, their alternating movements reduce movement resistance.

[0034] Specifically, in this embodiment, when multiple scraper assemblies are set, some scraper assemblies will inevitably have one side not close to the side plate 1. In order to fix the movement range of each scraper assembly, the bottom plate 3 is provided with a raised ridge 2 in the longitudinal direction. The raised ridge 2 can divide the bottom plate 3 into multiple spaces in the longitudinal direction, and each space corresponds to a scraper assembly. The raised ridge 2 can also guide the scraper assembly to avoid the scraper assembly from deviating or interfering with each other. Therefore, the scraper assembly is set on the bottom plate 3 between the raised ridges 2 or on the bottom plate 3 between the raised ridge 2 and the side plate 1, with the raised ridge 2 separating adjacent scraper assemblies.

[0035] In this embodiment, to control the position of the chain 5 and prevent it from jumping, the lower part of the side plate 1 is provided with a first U-shaped groove facing the middle of the scraper 4, and the chain 5 in the scraper assembly near the side plate 1 is located in the first U-shaped groove. Of course, when the scraper 4 of the scraper assembly extends out of the chain 5, the scraper 4 can also be located in the first U-shaped groove.

[0036] Specifically, when at least two scraper assemblies are set, the chains 5 of the scraper assemblies cannot all be close to the side plates 1, and some chains 5 are located in the middle of the bottom plate 3. Therefore, in order to facilitate the control of the position of the chains 5 and provide guidance for the movement of the chains 5, a raised ridge 2 is longitudinally provided on the bottom plate 3. The lower parts of both sides of the raised ridge 2 are provided with second U-shaped grooves 6 facing the scraper 4. The chains 5 of the scraper assembly that are close to the raised ridge 2 are located in the second U-shaped grooves 6. It should be noted that the raised ridge 2 can also play a role in separating materials, guiding the materials located on the raised ridge 2 to both sides; furthermore, the raised ridge 2 can also separate adjacent chains 5 of adjacent scraper assemblies to avoid interference between the chains 5.

[0037] More specifically, in order to improve the powder effect and prevent the material from accumulating on the upper part of the raised ridge 2, the upper cross section of the raised ridge 2 is triangular, that is, the raised ridge 2 has a structure that is pointed at the top and wide at the bottom, so that the material falls to both sides along the raised ridge 2.

[0038] More specifically, the scraper assembly has a first U-shaped groove on both sides, a raised ridge on the bottom plate, and a second U-shaped groove 6 on the raised ridge. The first U-shaped groove or the second U-shaped groove 6 is tapered on the side near the scraper 4. This tapering means that the inside of the U-shaped groove is higher than the outside, so as to prevent the chain 5 from extending out of the U-shaped groove, and at the same time provide guidance for the operation of the scraper to avoid the scraper assembly jumping.

[0039] More specifically, in this embodiment, there are two scraper assemblies, and a raised ridge 2 is provided on the bottom plate 3, which divides the bottom plate 3 of the carriage into two parts.

[0040] More specifically, there are three scraper assemblies. The base plate 3 is provided with two raised ridges 2, that is, a scraper assembly is provided between the two raised ridges 2, and a scraper assembly is provided on each side of the two raised ridges 2.

[0041] More specifically, in this embodiment, when multiple scraper assemblies are set, the vertical width of the carriage can be kept consistent, that is, there is no need for a design that is wider at the top and narrower at the bottom. At this time, the side plate 1 is set vertically. When the side plate is set vertically, the first U-shaped groove does not need to be set.

[0042] 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.
