Description

Technical fields:

[0001] This utility model relates to the field of dump truck technology, and in particular to a novel bulk material unloading truck body. Background technology:

[0002] Currently, some bulk material dump trucks on the market have a discharge structure with chains and scrapers installed inside the truck bed. For example, patent application CN209534841U discloses a truck dump bed where a ring chain is horizontally installed at the bottom of the bed via a drive shaft and a driven shaft. Several scrapers are mounted on the ring chain. During discharge, a motor drives the drive shaft to rotate, which in turn drives the ring chain. The scrapers on the ring chain then carry the material to the discharge port at the rear of the bed, completing the discharge. The disadvantages of this structure are: because the ring chain needs to go around the bed floor, with half of the chain above and half below the floor, it causes the bed floor to rise, reducing the internal volume and loading capacity for the same external dimensions. Furthermore, repairing or replacing damaged components hidden under the bed floor is difficult, and there is currently no good solution to these problems.

[0003] In summary, how to solve the problems of reduced internal volume and maintenance difficulties when the same external dimensions are achieved has become a pressing technical challenge for the industry. Utility Model Content:

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a new type of bulk material unloading truck body, which solves the problem that the internal volume of the truck body is reduced when the floor is raised, and also solves the problem that it is difficult to repair and replace the components hidden under the floor when they are damaged.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A novel bulk material unloading truck body includes a truck body, a first front axle located at the bottom of the front end of the inner side of the truck body, a second front axle located at the top of the front end of the inner side of the truck body, a rear axle and a discharge port located at the bottom of the rear end of the inner side of the truck body, and several ring chains wound on the first front axle, the second front axle and the rear axle, each ring chain being arranged in a triangular pattern, and a scraper installed on the ring chains, and the rear axle being connected to a drive device.

[0007] The second front axle is movably mounted on the side panel of the carriage, and the side panel of the carriage is provided with tensioning bolts that cooperate with the second front axle.

[0008] Several gears are installed on the first front axle, the second front axle, and the rear axle, and the gears are meshed with a ring chain.

[0009] The scraper includes hard scrapers and flexible scrapers arranged at intervals.

[0010] The scraper is a single, continuous piece, installed laterally on each ring chain.

[0011] The scraper is segmented and installed laterally on two adjacent annular chains.

[0012] The drive unit includes motors mounted at both ends of the rear axle.

[0013] The present invention adopts the above solution and has the following advantages:

[0014] By installing a first front axle at the bottom of the front end of the inner side of the carriage, a second front axle at the top of the front end of the inner side of the carriage, and a rear axle at the bottom of the rear end of the inner side of the carriage, and winding several ring chains on the first, second, and rear axles, with scrapers installed on the ring chains, the previous unloading transmission structure is overturned. All moving parts are located above the carriage floor, the height of the carriage floor is reduced, the internal volume of the carriage is increased under the same external dimensions, the loading capacity is increased, and all moving parts are exposed inside the carriage, making maintenance and replacement more convenient when damaged. Attached image description:

[0015] Figure 1 This is a three-dimensional structural diagram of the present invention.

[0016] Figure 2 This is a cross-sectional structural diagram of the present invention.

[0017] In the diagram, 1 is the carriage, 2 is the first front axle, 3 is the second front axle, 4 is the rear axle, 5 is the unloading port, 6 is the ring chain, 7 is the gear, 8 is the hard scraper, 9 is the flexible scraper, 10 is the motor, and 11 is the tensioning bolt. Detailed implementation method:

[0018] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0019] like Figure 1-2 As shown, a novel bulk material unloading truck body includes a truck body 1. A first front axle 2 is provided at the bottom of the front end of the inner side of the truck body 1, a second front axle 3 is provided at the top of the front end of the inner side of the truck body 1, and a rear axle 4 and a discharge port 5 are provided at the bottom of the rear end of the inner side of the truck body 1. The first front axle 2, the second front axle 3 and the rear axle 4 can rotate freely. Several ring chains 6 are wound on the first front axle 2, the second front axle 3 and the rear axle 4. Each ring chain 6 is arranged in a triangle. A scraper is installed on the ring chain 6. The rear axle 4 is connected to a drive device.

[0020] The second front axle 3 is movably mounted on the side panel of the carriage 1. The side panel of the carriage 1 is provided with a tensioning bolt 11 that cooperates with the second front axle 3. By rotating the tensioning bolt 11, the position of the second front axle 3 can be adjusted to tension the ring chain 6.

[0021] Several gears 7 are installed on the first front axle 2, the second front axle 3, and the rear axle 4 respectively. The gears 7 are meshed with the annular chain 6 and drive the annular chain 6 to rotate.

[0022] The scraper includes a hard scraper 8 and a flexible scraper 9 spaced apart. The hard scraper 8 can be made of wood, and the flexible scraper 9 can be made of rubber. The two scrapers work together to scrape the material cleanly.

[0023] The scraper can be installed as a single piece, horizontally mounted on each of the ring chains 6.

[0024] The scraper can be segmented and installed laterally on two adjacent annular chains 6.

[0025] The drive unit includes motors 10 mounted at both ends of the rear axle 4.

[0026] Working principle:

[0027] Motor 10 drives rear axle 4 to rotate, and gear 7 on rear axle 4 drives each ring chain 6 to rotate synchronously. First front axle 2 and second front axle 3 support each ring chain 6. When the ring chains 6 rotate, the scrapers on them can carry the material in the carriage 1 to the rear discharge port 5 for unloading. As the material in the carriage 1 gradually decreases, the height of the material at the rear decreases and gradually tilts downward. The top of the material is in an inclined shape that matches the inclined side of the ring chain 6, which can reduce the running resistance of the ring chain 6 and the scrapers. All moving parts are located above the floor of the carriage 1. The height of the floor of the carriage 1 is lower than before. Under the same external dimensions, the internal volume of the carriage 1 is increased, the loading capacity is increased, and all moving parts are exposed inside the carriage 1, making maintenance and replacement more convenient when damaged.

[0028] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0029] Any aspects of this utility model not described in detail are known to those skilled in the art.
