Description

Technical field:

[0001] The utility model belongs to the field of roadbed construction, in particular to an iron tailings powder roadbed filling and compacting device. Background technology:

[0002] During road construction, the roadbed is a crucial component. With the advancement of society, the use of tailings to prepare road base materials is gaining popularity. During roadbed construction, compaction is performed to improve the strength of the roadbed, requiring the use of a roadbed compactor. Existing roadbed compactors are typically low-priced and simple roller devices. A tractor, acting as the driving force, drives the roller device across the road surface, achieving the desired compaction effect.

[0003] In the prior art, a scraper is generally provided on the pressing roller device to remove the clay or other debris carried on the outer circumference of the pressing roller, thereby improving the compaction effect of the pressing roller device and making the compacted roadbed surface smoother. During the compaction operation, the pressing roller device needs to repeatedly roll the roadbed back and forth. In order to improve the scraping effect, the scraping end of the original scraper will form a certain angle with the outer circumference of the pressing roller, which results in the scraper being able to only remove the clay carried on the outer circumference of the pressing roller when it is moving forward, and the scraper cannot effectively remove the clay carried on the outer circumference of the pressing roller when the pressing roller device moves backward, resulting in a reduced clay scraping effect and a significant decrease in compaction efficiency. The roadbed surface cannot be flattened in time, thereby increasing the construction period of roadbed compaction. Utility model content:

[0004] The purpose of the utility model is to provide an iron tailings powder roadbed filling and compacting device, which overcomes the shortcomings of the above-mentioned prior art and effectively solves the existing problem of low efficiency of clay removal by the pressing rod device.

[0005] The content of the utility model: A device for compacting iron tailings powder roadbed filling, comprising a traction frame, a pressing rod installed on the traction frame, a V-shaped support frame installed on the crossbeam of the traction frame, scrapers installed on both side walls of the V-shaped support frame, the outer ends of the scrapers slidingly fit with the outer circumferential surface of the pressing rod, and an elastic pressing component provided on the pressing rod.

[0006] Furthermore, the elastic clamping assembly includes a sliding rod, the inner end of the sliding rod is fixedly connected to the inner side wall of the crossbeam of the traction frame, a sliding hole is opened on the V-shaped support frame, the sliding rod slides in the sliding hole, a spring is mounted on the sliding rod, the spring is located between the crossbeam of the traction frame and the V-shaped support frame, and a limiting cap is installed on the outer end of the sliding rod.

[0007] Furthermore, grooves are provided on both side walls of the V-shaped support frame, and the scrapers are inserted into the grooves.

[0008] Furthermore, the scraper and the groove are fixedly connected by bolts.

[0009] Furthermore, a chamfered corner matching the outer circumferential surface of the pressing roller is provided on the outer end of the scraper.

[0010] The beneficial effects of the utility model are as follows: by installing scrapers at both ends of the V-shaped support frame, the clay or other debris carried by the outer circumferential surface of the pressing roller during the forward and backward movement can be shoveled away, thereby improving the scraping effect, reducing the compaction efficiency, and the roadbed surface can be pressed more flat, shortening the construction period of roadbed compaction.

[0012] Figure 2 It is a top view of the utility model;

[0013] In the figure, 1 is a traction frame, 2 is a pressure rod, 3 is a V-shaped support frame, 4 is a scraper, 5 is a slide rod, 6 is a slide hole, 7 is a spring, 8 is a limit cap, 9 is a groove, and 10 is a bolt. Specific implementation method:

[0014] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings:

[0015] like Figures 1 to 2 As shown, a device for compacting iron tailings powder roadbed filling includes a traction frame 1, a pressure rod 2 is installed on the traction frame, a V-shaped support frame 3 is installed on the crossbeam of the traction frame 1, and scrapers 4 are installed on both side walls of the V-shaped support frame 3. The outer end of the scraper 4 slides in contact with the outer circumference of the pressure rod 2, and an elastic pressing component is provided on the pressure rod 2. The elastic pressing component includes a slide rod 5, the inner end of the slide rod 5 is fixedly connected to the inner side wall of the crossbeam of the traction frame 1, and the V-shaped support frame 3 is provided with a plurality of scrapers. A sliding hole 6 is provided, in which the sliding rod 5 slides, and a spring 7 is mounted on the sliding rod 5. The spring 7 is located between the crossbeam of the traction frame 1 and the V-shaped support frame 3. A limiting cap 8 is installed at the outer end of the sliding rod 5. Grooves 9 are provided on both side walls of the V-shaped support frame 3. The scraper 4 is inserted into the groove 9. The scraper 4 and the groove 9 are fixedly connected by bolts 10. A chamfer matching the outer circumferential surface of the pressing rod 2 is provided at the outer end of the scraper 4.

[0016] Specifically, the scrapers 4 installed at both ends of the V-shaped support frame 3 can remove the clay or other debris carried by the outer circumferential surface of the pressing roller 2 during the forward and backward movement.

[0017] During actual use, the hanging end of the traction frame 1 is first connected and fixed to the tractor. Under the drive of the tractor, the pressing roller 2 located on the traction frame 1 repeatedly compacts the roadbed. During this process, the scrapers 4 installed at both ends of the V-shaped support frame 3 can shovel away the clay or other debris carried on the outer circumference of the pressing roller 2 moving forward and backward, thereby improving the clay scraping effect.

[0018] Under the action of the spring 7, the V-shaped support frame 3 can slide on the slide rod 5, so that the scraping ends of the scrapers 4 installed at both ends of the V-shaped support frame 3 can always fit the outer circumferential surface of the pressing rod 2, thereby preventing the scrapers 4 from being unable to remove the clay in time during the wear process;

[0019] The scraper 4 is inserted into the groove 9 and fixed with bolts 10, so that the scraper 4 can be quickly assembled and disassembled with the V-shaped support frame 3. When the scraper 4 is worn out or damaged, it can be quickly disassembled and replaced.

[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
