[0029] Embodiment 1

[0030] The embodiment provides a rear door of a scraper truck, namely a rear door structure arranged at the rear part of the scraper truck, which comprises a rear door body, a lower part of the rear door body is provided with a discharge port 8 extending upward from the lower part, both sides of the discharge port 8 are provided with sliding rails, a sliding door 3 is arranged on the discharge port 8, and the sliding door 3 is slidably arranged on the sliding rails. Driving devices are arranged between the sliding door 3 and the rear door body, and the driving devices drive the sliding door 3 to move up and down.

[0031] The rear door of the scraper truck can drive the sliding door 3 to move up and down through the driving devices when unloading is needed, the driving devices can be any devices for driving the sliding door 3 to move up and down along the sliding rails, such as air cylinders, hydraulic cylinders, telescopic motors and chains. When the scraper truck is unloading, the goods are scraped to the rear part through the scraper, and then the goods flow out of the opened discharge port 8, thereby achieving unloading. Since the goods are unloaded from the discharge port 8, the width of the discharge port 8 through which the goods flow out is relatively small compared with the whole rear door body, and the conveying device can conveniently collect the goods unloaded from the discharge port 8.

[0032] Specifically, the rear door body comprises an upper plate body 1 and a lower plate body 2, the upper plate body 1 and the lower plate body 2 are rotationally connected, and the lower plate body 2 is locked on the carriage of the scraper truck through locking pieces, that is, the lower plate body 2 and the carriage are connected in an openable and closable mode through any mode such as a bolt, a plug rod and a handle. Since the upper plate body and the lower plate body are rotationally connected, the lower plate body can be rotated and flipped relative to the upper plate body, and the lower plate body can be opened through any mode such as a hydraulic cylinder and an air cylinder when unloading is needed, and unloading is achieved through the opened lower plate body.

[0033] More specifically, in the embodiment, the sliding door 3 is arranged on the lower plate body 2. The driving devices comprise telescopic devices 4, both ends of the telescopic devices 4 are rotationally connected to the sliding door 3 and the upper plate body 1 respectively, the telescopic devices 4 can drive the sliding door to move up and down, thereby achieving opening and closing of the discharge port. Meanwhile, in the embodiment, when the sliding door 3 is fixed through any mode such as a locking pin or the sliding door 3 moves to the highest position, when the telescopic devices 4 are retracted, the telescopic devices 4 can flip the lower plate body 2 upward and rearward when the locking pieces of the lower plate body 2 are unlocked, thereby opening the lower plate body 2, achieving bulk unloading, improving unloading efficiency, and increasing an unloading mode.

[0034] Specifically, in the embodiment, the sliding door 3 can be locked through locking devices on the basis of being capable of sliding along the sliding rails, the locking can be locking when the sliding door 3 closes the discharge port 8, so that the sliding door 3 is kept stationary on the lower plate body 2 when the lower plate body 2 is flipped through the telescopic devices 4, the locking can also be locking when the sliding door 3 opens the discharge port 8, so as to fix the sliding door 3 and keep the discharge port 8 open, and the locking can be any locking mode such as pin locking in the prior art.

[0035] Specifically, in the embodiment, the rear door body can also be provided as a conventional rear flip door structure, that is, a conventional rear flip door structure in rear flipper, conveyor belt transport vehicle and scraper vehicle and the like, that is, the rear door body is rotatably installed on the rear vertical column of the vehicle compartment of the scraper vehicle, and in this way, the rear door body can be driven to flip over as a whole by the rear door opening structure installed on the rear door body.

[0036] Specifically, in the embodiment, the scraper vehicle comprises a bottom plate, and a scraper assembly is arranged around the bottom plate. In order to facilitate unloading and make the goods flow out of the discharge port 8 more quickly, a hopper 6 extending downward is further arranged at the rear lower part of the bottom plate. The material transported by the scraper assembly falls into the hopper 6 when reaching the rear part of the bottom plate, and then flows out of the discharge port 8 at the rear part of the hopper. Through the arrangement of the hopper 6, the material can be first moved into the hopper 6, so as to avoid the accumulation of the material near the discharge port 8.

[0037] More specifically, in the embodiment, the hopper 6 comprises an inclined plate 7 extending obliquely downward from top to bottom, that is, a slope extending downward and rearward from the bottom plate, so as to make the material flow into the rear hopper 6. It should be noted that the cross section of the hopper 6 can be U-shaped.

[0038] Specifically, in the embodiment, in order to avoid the overflow of the material from the rear door body and improve the sealing performance of the rear door of the scraper vehicle, a clamping plate 5 extending into the vehicle compartment is arranged at the inner side of the sliding door 3, and the clamping plate 5 is attached to the bottom plate of the vehicle compartment after the sliding door 3 moves downward. When empty, the sliding door 3 moves downward to close the discharge port 8, and at this time, the clamping plate 5 is clamped on the bottom plate of the vehicle compartment, so as to realize the sealing between the bottom plate and the rear door body. When unloading is needed, the clamping plate 5 is lifted or flipped by moving the sliding door 3 or other ways, so that the clamping plate 5 is separated from the bottom plate, and then the unloading is realized. In the embodiment, the clamping plate 5 and the sliding door 3 are integrally arranged, and when the sliding door 3 moves upward, the clamping plate 5 moves upward at the same time, and at this time, the clamping plate 5 is separated from the bottom plate. The material scraped rearward from the bottom plate by the scraper can be smoothly moved to the hopper 6 and the discharge port 8 at the rear part of the bottom plate.

[0039] More specifically, in the embodiment, in order to improve the sealing performance, the clamping plate 5 is made of rubber plate away from the sliding door 3.

[0040] Of course, the above-mentioned is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and the contents of the drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model, and should be protected by the utility model.
