Description

Technical Field

[0001] This utility model relates to a dump truck, specifically a rear-tipping dump truck with a rectangular structure in which the cargo box is a container or similar container and the cargo box can be tilted backward. Background Technology

[0002] A container-type rear-tipping dump truck refers to a container-type rear-tipping dump truck that mounts a container or similar container-shaped cargo box on a frame and has a rear-tipping structure between the frame and the cargo box so that the cargo box can be tilted backward.

[0003] However, most existing container-type rear-tipping dump trucks have a rear-tipping door structure on the rear side panel of the truck body. When unloading is required, the rear door flips back as a whole, the rear of the truck body opens as a whole, and the goods are unloaded from the rear of the truck body.

[0004] However, when transporting goods such as grains and powdery materials, it is necessary to unload the goods onto conveyor belts or other transport devices. Existing containerized rear-dump trucks often result in the goods being unloaded in a scattered manner, making it impossible to concentrate the goods. At the same time, when the unloading rate varies greatly from the rear of the truck bed, it can easily lead to instability of the lifting device. Utility Model Content

[0005] This utility model provides a container-type rear-tipping dump truck to solve the following problem: existing container-type rear-tipping dump trucks cannot achieve centralized unloading.

[0006] This utility model provides a container-type rear-tipping dump truck, which includes a main frame, on which a container-type cargo box is mounted. A lifting device is provided between the cargo box and the main frame, with both ends of the lifting device rotatably connected to the main frame and the cargo box, respectively. The rear of the cargo box is rotatably mounted on the main frame. The cargo box includes a front side panel, left and right side panels, and a rear side panel. A discharge port is provided at the lower part of the rear side panel, and a discharge door is provided on the discharge port. Guide plates are provided on both sides of the discharge port inside the cargo box.

[0007] Preferably, the discharge port is located in the middle of the lateral direction of the rear side plate.

[0008] Preferably, the guide plate extends obliquely forward from the rear side plate to the left and right side plates, and the guide plate forms a figure-eight shaped guide structure on the rear side of the carriage.

[0009] Preferably, the guide plate extends downward and inward at an angle from both sides to the middle.

[0010] Preferably, a sealing plate is provided on the upper part of the guide plate, the lower end of the sealing plate is connected to the guide plate, and the upper part of the sealing plate is connected to the left and right side plates and the rear side plate respectively.

[0011] Preferably, the sealing plate is triangular, and its three sides are respectively connected to the guide plate, the left and right side plates and the rear side plate.

[0012] Preferably, the front part of the left and right side panels is further provided with an extension plate extending forward, and the front part of the extension plate is provided with a front door. The extension plate, the front door and the front side panels form a lifting device cavity, and the lifting device is located in the lifting device cavity.

[0013] Preferably, the front door is a left-right opening door.

[0014] Preferably, an outwardly extending discharge ring is provided at the discharge port, and the discharge ring is used to install the discharge pipe for guiding the material.

[0015] Preferably, a rear door is also provided at the rear of the rear side panel, and the rear door is a double door.

[0016] Compared with the prior art, the container-type rear-tipping dump truck provided by this utility model has the following beneficial technical effects:

[0017] The aforementioned container-type rear-tipping dump truck mounts a container or similar container-shaped cargo box on a chassis, and achieves rear-tipping of the cargo box through a lifting device and a rotating installation. A discharge port is located at the rear of the cargo box, specifically at the lower part of the rear side panel. When unloading is required, simply open the discharge port, and the lifting device tilts the cargo box backward, allowing the material inside to be discharged through the discharge port and then transferred to a designated location such as a conveyor, improving unloading convenience. Furthermore, the material discharge rate from the discharge port varies minimally, preventing instability in the lifting device when unloading efficiency suddenly increases.

[0018] It should be noted that the container-type truck body has a rectangular structure. When unloading through the unloading port, the material tends to accumulate on both sides of the unloading port, resulting in incomplete unloading. The container-type rear-tipping dump truck provided by this utility model has guide plates installed on both sides of the unloading port inside the truck body. When the material moves from front to back, it can be guided to the unloading port by the guide plates, thereby improving unloading efficiency and avoiding the problem of incomplete unloading and some material not being able to be unloaded.

[0032] This embodiment provides a containerized rear-tipping dump truck, which includes a main frame 1. A containerized cargo box 2 is mounted on the main frame 1. A lifting device is provided between the cargo box 2 and the main frame 1. The lifting device is generally located at the front, but when the lifting device is a belly-lift type, it can also be located in the middle. The two ends of the lifting device are rotatably connected to the main frame 1 and the cargo box 2, respectively. The rear of the cargo box 2 is rotatably mounted on the main frame 1. The cargo box 2 includes a front side panel, left and right side panels 5, and a rear side panel 3. A discharge port 4 is provided at the lower part of the rear side panel 3. A discharge door is provided on the discharge port 4. Guide plates 6 are provided on both sides of the discharge port 4 inside the cargo box 2.

[0033] The aforementioned container-type rear-tipping dump truck mounts a container or similar container-shaped cargo box 2 on a frame 1, and achieves rear-tipping of the cargo box 2 through a lifting device and a rotating installation. A discharge port 4 is located at the rear of the cargo box 2, specifically at the lower part of the rear side panel 3. When unloading is required, simply open the discharge port 4, and the lifting device will lift the cargo box 2 backward, allowing the material inside to move backward and downward under gravity. During this material movement, the material on both sides is moved to the discharge port 4 via guide plates 6, where it is discharged from the center and sides, and then unloaded to a designated location such as a conveyor, improving unloading convenience.

[0034] Specifically, in this embodiment, the discharge port 4 is located in the middle of the lateral direction of the rear side plate 3 so that the material can be discharged quickly.

[0035] More specifically, in this embodiment, a specific implementation of the guide plate 6 is also provided, such as... Figure 2 and Figure 3As shown, the guide plate 6 extends obliquely forward from the rear side plate 3 to the left and right side plates 5, and the guide plate 6 forms a figure-eight shaped guide structure on the rear side of the carriage 2.

[0036] More specifically, in this embodiment, in order to facilitate the concentration of material at the upper part to the discharge port 4 and improve the discharge efficiency at the discharge port 4, such as... Figure 2 As shown, the guide plate 6 extends downward and inward from both sides to the middle. This arrangement allows the material at the top to flow through the inclined guide plate 6 to the middle of the carriage 2.

[0037] More specifically, in this embodiment, in order to increase the storage volume and avoid the guide plate 6 occupying too much space, the guide plate 6 is only set at the height of the discharge port 4. The upper part of the discharge port 4 does not need to be set with the guide plate 6. In order to block the space behind the guide plate 6, a sealing plate 7 is set on the upper part of the guide plate 6. The lower end of the sealing plate 7 is connected to the guide plate 6, and the upper part of the sealing plate 7 is connected to the left and right side plates 5 and the rear side plate 3 respectively.

[0038] More specifically, this embodiment also provides the specific structure of the sealing plate 7, which is triangular in shape, and the three sides of the sealing plate 7 are respectively connected to the guide plate 6, the left and right side plates 5 and the rear side plate 3.

[0039] Specifically, in this embodiment, in order to hide the lifting device, the front part of the left and right side panels 5 is also provided with an extension plate that extends forward. The front part of the extension plate is provided with a front door. The extension plate, the front door and the front side panels form a cavity for the lifting device, and the lifting device is located in the cavity for the lifting device.

[0040] More specifically, in order to facilitate the maintenance and repair of the lifting device and to allow staff to easily access and approach the lifting device, the front door is a left-right opening door. It should be noted that the left-right opening door can form the entire front door or it can be located only in the middle of the front door.

[0041] Specifically, in this embodiment, the above-mentioned container-type rear-tipping dump truck has an outwardly extending unloading ring at the unloading port 4. The unloading ring can be fitted with an unloading pipe to guide the material to a designated location and improve the flexibility of unloading.

[0042] Specifically, in this embodiment, the rear of the carriage 2 can be configured as a door-in-door structure, that is, a discharge port 4 is provided on the rear side panel 3, and a discharge door is provided on the discharge port 4. The discharge door can be a valve or any existing structure. A rear door is also provided at the rear of the rear side panel 3. The rear door is a double door, that is, the rear door includes a left door and a right door. The left side panel and the right door rotate around the pivot joint on both sides. When the left side door and the right door are closed, they block the rear of the rear side panel 3. When the left side door and the right door are flipped to both sides, the rear of the rear side panel 3 is opened.

[0043] 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.
