Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a dump mechanism of a dump semitrailer. Background Art

[0002] Dump semi-trailers are suitable for the transportation of bulk and scattered goods such as coal, ore, earth, and building materials. They store materials in a larger bucket, and tilt the bucket when unloading, so that the materials slide along the tilted bucket to the target location. When the dump semi-trailer is in use, after the materials slide out of the bucket, some mud and other materials will still adhere to the inner wall of the bucket. If the materials attached to the inner wall of the bucket need to be unloaded, they need to be cleaned manually with tools such as brooms, which takes a lot of time.

[0003] At present, the prior art CN214728385U discloses an efficient dump mechanism of a dump semi-trailer, including a bucket, a revolving door and a cleaning mechanism. The cleaning mechanism includes a motor, a reciprocating screw, a movable plate, two brush plates and a connecting rope. The side walls of the two brush plates are provided with bristles, and the materials attached to the inner wall of the bucket are scraped off by the bristles. Then, the bucket is tilted to make the materials attached to the inner wall of the bucket slide out of the bucket. No manual cleaning is required, thereby improving the efficiency of unloading.

[0004] However, in the above manner, the bristles can only scrape off the materials attached to the inner side wall of the bucket, but cannot scrape off the materials attached to the bottom wall of the bucket, so the unloading effect is insufficient. Utility Model Content

[0027] Among them, the slide rail 104 is fixedly connected to the bucket 101 and is located on the top of the bucket 101; the slider 105 is slidably connected to the slide rail 104 and is located on the inner side of the slide rail 104; the threaded screw 106 is rotatably connected to the slide rail 104, is threadedly connected to the slider 105, and is located on the inner side of the slide rail 104; the motor 107 is fixedly connected to the slide rail 104, and the output end of the motor 107 is fixedly connected to the threaded screw 106 and is located on the side of the slide rail 104; the connecting rod 108 is fixedly connected to the slider 105 and is located on the side of the slider 105; the scraper 109 is fixedly connected to the connecting rod 108 and is located on the side of the connecting rod 108. When unloading, the revolving door 102 is rotated away from the bucket 101, and the semitrailer drives the bucket 101 to flip so that the material is discharged from the opening of the bucket 101. By turning on the motor 107, the motor 107 drives the slider 105 to move along the slide rail 104, and the slider 105 drives the scraper 109 to move via the connecting rod 108. The scraper 109 moves toward the revolving door 102. During the movement of the scraper 109, the material on the inner side wall and the inner bottom wall of the bucket 101 is scraped off, thereby improving the unloading efficiency.

[0028] Secondly, the guide member 110 is arranged on the side of the scraper 109. The guide member 110 can provide guidance for the scraper 109 when the scraper 109 moves.

[0029] Meanwhile, the guide rail 111 is fixedly connected to the bucket 101 and is located at the top of the bucket 101; the support 112 is fixedly connected to the scraper 109 and is located at the top of the scraper 109; the rotating shaft 113 is fixedly connected to the support 112 and is located at the side of the support 112; the pulley 114 is rotatably connected to the rotating shaft 113 and is located at the inner side of the guide rail 111. When the scraper 109 moves, it drives the support 112, the rotating shaft 113 and the pulley 114 to move, so that the pulley 114 slides along the guide rail 111, and the guide rail 111 provides guidance for the rotating shaft 113 and the pulley 114, so that the scraper 109 can provide guidance for the scraper 109 when it moves, so that the scraper 109 moves more stably and smoothly.

[0030] When the utility model is used for unloading, the revolving door 102 is rotated away from the bucket 101, and the bucket 101 is driven to flip by the semitrailer, so that the material is discharged from the opening of the bucket 101, and the motor 107 is turned on, and the motor 107 drives the slider 105 to move along the slide rail 104, and the slider 105 drives the scraper 109 to move via the connecting rod 108, and the scraper 109 moves toward the revolving door 102. During the movement of the scraper 109, the material on the inner side wall and the inner bottom wall of the bucket 101 is scraped off, thereby improving the unloading efficiency. When the scraper 109 moves, it will drive the support 112, the rotating shaft 113 and the pulley 114 to move, so that the pulley 114 slides along the guide rail 111. The guide rail 111 provides guidance for the rotating shaft 113 and the pulley 114, thereby providing guidance for the scraper 109 when the scraper 109 moves, making the scraper 109 move more stably and smoothly.

[0031] The second embodiment of the present application is:

[0032] Based on the first embodiment, please refer to Figure 4 ,in, Figure 4 It is a schematic diagram of the overall structure of the second embodiment of the utility model.

[0033] The dump mechanism of a dump semi-trailer provided by the utility model further comprises two fixing components 201 ; the fixing components 201 comprise a mounting frame 202 , a screw rod 203 , a bearing 204 , a guide block 205 , a baffle 206 and a handle 207 .

[0034] According to this specific embodiment, two fixing components 201 are mirror-imaged and arranged on both sides of the bucket 101. The fixing components 201 can limit and fix the revolving door 102 to prevent the revolving door 102 from turning over and causing the material to flow out during the material transportation process.

[0035] Among them, the mounting frame 202 is fixedly connected to the truck bucket 101 and is located on the side of the truck bucket 101; the screw rod 203 is threadedly connected to the mounting frame 202 and passes through the mounting frame 202; the inner ring of the bearing 204 is fixedly connected to the screw rod 203 and is located on the side of the screw rod 203; the guide block 205 is slidably connected to the mounting frame 202 and is located on the side of the mounting frame 202; the baffle 206 is fixedly connected to the outer ring of the bearing 204, fixedly connected to the guide block 205, and is located on the side of the guide block 205. The screw rod 203 is rotated forward so that the screw rod 203 drives the bearing 204 and the baffle plate 206 to approach the rotating door 102, and the baffle plate 206 is used to limit and fix the rotating door 102 to prevent the rotating door 102 from turning over and causing the material to flow out during the transportation of materials; when unloading is required, the screw rod 203 is reversed so that the screw rod 203 drives the bearing 204 and the baffle plate 206 away from the rotating door 102, and the limit on the rotating door 102 is released, and then the rotating door 102 can be turned over to discharge the material from the truck 101. The guide block 205 provides guidance for the baffle plate 206 to prevent the baffle plate 206 from rotating.

[0036] Secondly, the handle 207 is fixedly connected to the screw rod 203 and is located at an end of the screw rod 203 away from the bearing 204. The user can rotate the screw rod 203 by holding the handle 207.

[0037] When the utility model is used for unloading, the screw rod 203 is reversed so that the screw rod 203 drives the bearing 204 and the baffle plate 206 away from the revolving door 102, and the limit on the revolving door 102 is released. Then the revolving door 102 is rotated away from the bucket 101, and the bucket 101 is driven to flip by the semi-trailer so that the material is discharged from the opening of the bucket 101. By turning on the motor 107, the motor 107 drives the slider 105 to move along the slide rail 104, and the slider 105 drives the scraper 109 to move via the connecting rod 108. The scraper 109 moves toward the direction of the revolving door 102. During the movement of the scraper 109, the material on the inner side wall and the inner bottom wall of the bucket 101 is scraped off, thereby improving the unloading efficiency. When the scraper 109 moves, it will drive the support 112, the rotating shaft 113 and the pulley 114 to move, so that the pulley 114 slides along the guide rail 111. The guide rail 111 provides guidance for the rotating shaft 113 and the pulley 114, thereby providing guidance for the scraper 109 when the scraper 109 moves, making the scraper 109 move more stably and smoothly.
