Description

Technical Field

[0001] This utility model relates to a transport vehicle, specifically a scraper-type 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 scrapers are mostly made of steel. As the scraper moves at the bottom of the truck bed, it collides with the floor and materials, which can easily lead to wear, bending and deformation of the scraper. At the same time, the scraper is prone to jumping during the collision, which can leave gaps between the scraper and the floor of the truck bed, resulting in incomplete unloading and material residue at the bottom of the truck bed. Utility Model Content

[0004] The main purpose of this utility model is to provide a scraper-type dump truck to solve the problems of easy wear and deformation of scrapers and incomplete material cleaning in the prior art.

[0005] This utility model provides a scraper-type dump truck, which includes a truck body, the truck body including side plates and a bottom plate, and a scraper assembly provided on the bottom plate. The scraper assembly includes chains on the left and right sides and a scraper between the two chains. A sealing plate is provided on the scraper, the sealing plate including a rear sealing plate, which is disposed on the rear end face of the scraper.

[0006] Preferably, the rear sealing plate extends downward to the lower end of the rear end face of the scraper, and extends downward by 0.1 to 3 cm.

[0007] Preferably, the rear sealing plate extends upward to the upper end of the rear end face of the scraper, and extends upward by 0.1 to 3 cm.

[0008] Preferably, the sealing plate is a rubber plate.

[0009] Preferably, the scraper assembly is provided with multiple scrapers, and the sealing plate is spaced apart on each scraper.

[0010] Preferably, the scraper and the sealing plate are provided with corresponding mounting holes, and the sealing plate is mounted on the scraper by bolts passing through the mounting holes.

[0011] Preferably, the bolt also includes a washer plate located at the rear of the sealing plate. This washer plate may be elongated and used to press the sealing plate together while preventing the bolt and the sealing plate from detaching from each other.

[0012] Preferably, there are multiple scraper assemblies, each of which is arranged longitudinally and parallel to the floor of the carriage.

[0013] The scraper-type dump truck provided by this utility model has the following advantages compared with the prior art:

[0014] The aforementioned scraper-type dump truck has a rear sealing plate installed on the scraper. The rear sealing plate is located on the rear end face of the scraper. When the scraper moves on the floor of the truck body, the rear part directly abuts against the cargo and pushes the cargo backward. At this time, the sealing plate can play a buffering role to avoid rapid impact damage to the scraper. It can also avoid direct collision between the scraper and the material, reducing friction damage.

[0015] Furthermore, the sealing plate is gentler than scrapers made of metal such as steel plates. When harder materials at the front or the floor of the carriage come into contact with the scraper, the sealing plate can also contact the floor first and adhere to the floor, preventing the scraper from jumping, preventing material residue under the scraper, and preventing the jumping scraper from damaging other structures of the scraper assembly, thereby improving the life of the scraper assembly.

[0029] Example 1

[0030] This embodiment provides a scraper-type dump truck, which includes a truck body, side panels, and a floor plate. A scraper assembly is mounted on the floor plate, comprising chains 3 on both sides and a scraper 1 between the two chains 3. Of course, moving the scraper 1 via ropes or other means is also an equivalent solution in this embodiment. In this embodiment, a sealing plate is mounted on the scraper 1, including a rear sealing plate 2, which is disposed on the rear end face of the scraper 1.

[0031] In the aforementioned scraper-type dump truck, when unloading is required, the chain 3 moves backward, simultaneously driving the scraper 1 backward. The scraper 1 then carries the material backward, thereby unloading the material. When the scraper 1 moves backward, its rear end directly contacts the material. In this embodiment, a rear sealing plate 2 is provided on the scraper 1, located on the rear end face of the scraper 1. When the material impacts the scraper 1, the sealing plate can buffer the impact, preventing rapid impact damage to the scraper 1. It also prevents direct collision between the scraper 1 and the material, reducing friction. Furthermore, the sealing plate is more flexible than the scraper 1 made of metal such as steel plates. When harder materials at the front or the floor of the truck bed come into contact with the scraper 1, it can prevent the scraper 1 from jumping, keeping the scraper 1 in contact with the floor, preventing material residue under the scraper 1, and preventing the jumping scraper 1 from damaging other structures of the scraper assembly, thus improving the lifespan of the scraper assembly.

[0032] Specifically, in this embodiment, in order to improve the protective effect of the sealing plate and to make the scraper 1 fit better against the bottom plate, so that the sealing plate buffers the collision between the scraper 1 and the bottom plate, the rear sealing plate 2 extends downward to the lower end of the rear end face of the scraper 1 and extends downward by 0.1 to 3 cm. With this setting, the lower end of the rear sealing plate 2 can abut against the bottom plate of the carriage, so that the scraper 1 scrapes the material more thoroughly, and also buffers the force between the scraper 1 and the bottom plate of the carriage.

[0033] More specifically, in order to better protect the upper part of the scraper 1 and allow the sealing plate to withstand the impact of the material, the rear sealing plate 2 extends upward to the upper end of the rear end face of the scraper 1 and extends upward by 0.1 to 3 cm.

[0034] Specifically, in this embodiment, the sealing plate is a rubber plate.

[0035] Specifically, in this embodiment, the scraper assembly has multiple scrapers 1, but not all scrapers 1 need to be equipped with a sealing plate. In this embodiment, the sealing plates are spaced apart on each scraper 1, that is, one of every two adjacent scrapers 1 is equipped with a sealing plate.

[0036] Specifically, in this embodiment, to facilitate the installation of the sealing plate, the scraper 1 and the sealing plate are provided with corresponding mounting holes. The sealing plate is installed on the scraper 1 by bolts passing through the mounting holes. It should be noted that, in order to better compress the sealing plate and also to prevent the sealing plate from falling off the bolt, a gasket plate can be provided on the rear end face of the sealing plate. The sealing plate is compressed by the gasket plate, which is generally a long strip of iron plate. When it is necessary to protect the upper part of the scraper, the upper end of the gasket plate can extend forward and also be on the upper end of the scraper, that is, the gasket plate is L-shaped. At this time, the upper part of the sealing plate is covered by the gasket plate, and only the lower part can protrude from the lower end face of the scraper.

[0037] Specifically, in order to reduce the resistance of each scraper assembly and to increase the width of the lower part of the carriage, there are multiple scraper assemblies, each scraper assembly is arranged longitudinally and parallel to the bottom plate of the carriage, and each adjacent scraper 1 can be spaced apart by raised ridges.

[0038] 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.
