Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete mixing drum cleaning technology, and in particular to a rapid cleaning device for concrete mixing drums. Background Technology
[0002] When mixing concrete, cement, sand and gravel aggregates and water are poured into the mixing drum of a concrete mixer, and then the machine is started to mix these materials into a concrete mixture. However, after mixing these materials, it is necessary to clean the concrete residue remaining on the inner wall of the concrete mixing drum.
[0003] After the existing concrete mixing drum has finished mixing the concrete, a layer of concrete will inevitably remain on its inner wall. If these residues are not cleaned in time, they will gradually harden and solidify over time during the natural cooling process, forming hard-to-remove lumps. This increases the difficulty and time cost of cleaning. Therefore, a rapid cleaning device for concrete mixing drums is proposed to solve the above problems. Utility Model Content

[0024] like Figure 1-4As shown, the present invention proposes a rapid cleaning device for concrete mixing drum, comprising two sets of columns 1, a top plate 7, and a support frame 4. The bottom sides of the top plate 7 are connected to the support frame 4 by two sets of columns 1 respectively. A side plate 2 is provided between each set of two columns 1. A third electric push rod 10 is symmetrically distributed on each side plate 2. The telescopic shafts of the third electric push rods 10 on both sides are connected to clamping plates 18 respectively through a first disassembly and assembly assembly. The clamping plates 18 are symmetrically distributed.
[0025] The top of the top plate 7 is provided with a second electric push rod 6. The telescopic shaft of the second electric push rod 6 passes through the top plate 7, and the telescopic shaft of the top plate 7 is connected to the connecting cylinder 9 through the second disassembly assembly. The bottom edge of the connecting cylinder 9 is provided with an annular cutter 12. The annular cutter 12 is made of hard alloy or special alloy steel to ensure that the scraper can effectively scrape off the hardened concrete residue while reducing its own wear.
[0026] The outer wall of the connecting cylinder 9 is smooth and is adapted to the inner wall of the concrete mixing drum.
[0027] In this invention, during use, the first and second disassembly components allow for the replacement of the connecting cylinder 9 and clamping plate 18, which are compatible with the concrete mixing drum. The drum is then moved above the concrete mixing drum, and the third electric push rods 10 on both sides are activated. This causes the clamping plates 18 on both sides to move relative to each other, allowing the concrete mixing drum to be aligned and limited. Then, the second electric push rod 6 is activated, extending and causing the third electric push rod 10 to descend via the connecting cylinder 9. This scrapes away residual concrete from the inner wall of the concrete mixing drum, effectively removing the concrete and solving the problem of cleaning residual concrete.
[0028] In an optional embodiment, the first disassembly and assembly assembly includes a mounting base 16, threaded rods 14, a second limiting block 15, and a fixing nut 17. The mounting base 16 is disposed on the telescopic shaft of the third electric push rod 10, the second limiting block 15 is disposed on the side of the clamping plate 18, and a plurality of threaded rods 14 are disposed in the groove of the mounting base 16. The second limiting block 15 is inserted into the plurality of matching threaded rods 14 through a pre-through opening, and the top of the threaded rod 14 is threadedly connected to the fixing nut 17.
[0029] It should be noted that when the clamping plate 18 needs to be replaced, the fixing nuts 17 on the multiple threaded rods 14 are rotated off, and then the second limiting block 15 connected to the clamping plate 18 is removed from the multiple threaded rods 14. Then the clamping plate 18 to be replaced is taken out, and the second limiting block 15 connected to the clamping plate 18 is inserted into the multiple threaded rods 14 through the multiple openings. At this time, the second limiting block 15 is located in the groove of the mounting base 16. Then, the fixing nuts 17 are rotated in the opposite direction to connect with the multiple threaded rods 14, thereby fixing the second limiting block 15 in the groove of the mounting base 16, thus completing the replacement of the clamping plate 18.
[0030] In an optional embodiment, the second disassembly assembly includes a fixing bolt 19, a first limiting block 8, and a limiting groove plate 11. The limiting groove plate 11 is disposed on the telescopic shaft of the second electric push rod 6. The first limiting block 8 is inserted into the groove opened in the limiting groove plate 11. The fixing bolts 19 on both sides pass through the two sides of the first limiting block 8 and extend into the interior of the limiting groove plate 11. The fixing bolts 19 and the limiting groove plate 11 are threadedly connected.
[0031] It should be noted that when the connecting cylinder 9 needs to be replaced, the fixing bolts 19 on both sides are rotated to remove them from both sides of the first limiting insert 8, thereby canceling the limitation of the first limiting insert 8. At this time, the first limiting insert 8 can be removed from the groove of the limiting groove plate 11, and the connecting cylinder 9 can be replaced. The first limiting insert 8 at the top of the replaced connecting cylinder 9 is inserted into the groove of the limiting groove plate 11, and the fixing bolts 19 are used to fix the first limiting insert 8 in the groove of the limiting groove plate 11, thereby achieving the fixation of the connecting cylinder 9.
[0032] In an optional embodiment, casters 13 are provided at both ends of the bottom of the support frame 4.
[0033] It should be noted that the multiple casters 13 enable the entire device to move.
[0034] In an optional embodiment, a plurality of first electric push rods 3 are provided at the middle of the upper end of the support frame 4, and the telescopic shafts of the plurality of first electric push rods 3 pass through the support frame 4 connected thereto and are connected to the support plate 5.
[0035] It should be noted that when it is necessary to remove the residual concrete on the inner wall of the concrete mixing drum, the multiple first electric push rods 3 above the support frames 4 on both sides are activated, so that the telescopic shafts of the multiple first electric push rods 3 are extended, thereby driving the support plates 5 on both sides to descend and the support frames 4 to rise. At this time, the casters 13 do not contact the ground, preventing the entire device from moving, making the cleaning of the residual concrete on the inner wall of the concrete mixing drum more stable.
[0036] In an optional embodiment, a through hole is provided circumferentially at the edge of the upper end face of the connecting cylinder 9.
[0037] It should be noted that multiple through holes allow the air conditioner to circulate with the outside when the connecting cylinder 9 moves within the concrete mixing drum, ensuring that the connecting cylinder 9 can move smoothly within the concrete mixing drum.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
