Description

Technical Field

[0001] The utility model relates to the technical field of mortar smoothing machines, in particular to a mortar smoothing machine with a detachable brush. Background Art

[0002] Cement grouting asphalt pavement has been regarded as a special pavement due to its superior ability to resist deformation. Usually, cement grouting asphalt pavement is made of a single void ratio (25-35%) asphalt mixture skeleton infused with high-fluidity cement mortar. Its construction process mainly includes: laying of base asphalt mixture, mixing of cement mortar, impregnation of cement mortar, scraping and leveling of surface cement mortar, and curing. Among them, scraping and leveling of surface cement mortar is to scrape and clean the cement mortar remaining on the surface with manual or automatic scraper equipment after the cement mortar is fully impregnated, so as to expose the uneven surface of the base asphalt, thereby improving the friction coefficient of the pavement, and at the same time avoiding shrinkage and cracking of the surface cement mortar after hardening into layers.

[0003] With the development of science and technology, mechanized mortar trowels have begun to replace manual trowel work, and there are four-wheel driving mortar trowels that allow the driver to sit on the mortar trowel and use the wheels to work on the ground to complete the troweling of the cement mortar on the ground. Usually, brushes are set at the front and rear ends of the four-wheel driving mortar trowel to smooth the ground, but the structure of the brush is usually fixed and cannot be quickly disassembled and replaced, which makes it inconvenient to disassemble during subsequent maintenance and cleaning; therefore, a mortar trowel with a detachable brush is proposed to solve the above problems.

A latch groove 11 is arranged on the front end surface of the side plate 6, and the position of the latch groove 11 is consistent with the latch groove 11. The pin 9 corresponds to the card pin 9, and the card pin 9 is movably engaged in the inside of the card slot 11, and the card slot 11 is connected to the front and rear ends of the side plate 6. The first limit grooves 10 are symmetrically arranged on both sides of the upper end of the side plate 6, and the first limit groove 10 is connected to the card slot 11. The card pin 9 and the side plate 6 are connected and fixed by a limit plate 14, and the limit plate 14 is movably engaged in the inside of the second limit groove 15 and the first limit groove 10. A second connecting rod 4 is arranged at the rear end of the mortar leveling machine body 1, and a second brush 18 is arranged below the second connecting rod 4.

[0021] By loosening the connecting bolt 8 and disengaging it from the threaded hole 12 and the first through hole 13, the limiting plate 14 can be pulled out from the first limiting groove 10 and the second limiting groove 15. Without the fixing of the limiting plate 14, the bayonet 9 and the side plate 6 can enable the first brush 7 to quickly detach from the front end of the dozer 2, thereby facilitating disassembly.

[0022] like Figure 2 A threaded hole 12 is provided at the front end of the side plate 6, and the threaded hole 12 is connected to the interior of the first limiting groove 10. A first through hole 13 is provided at the front end of the limiting plate 14. The limiting plate 14 and the side plate 6 are connected and fixed by connecting bolts 8, and the connecting bolts 8 pass through the threaded hole 12 and engage with the first through hole 13. The connecting bolts 8 are used to fix the engaging connection between the side plate 6 and the dozer 2.

[0023] like Figure 3 , fixing rods 5 are symmetrically arranged on both sides of the front end of the second connecting rod 4, the fixing rod 5 and the second connecting rod 4 are connected by a connecting shaft, and the fixing rod 5 swings on the outside of the second connecting rod 4 through the connecting shaft, and fixing seats 19 are symmetrically arranged on both sides of the upper end of the second brush 18, and the fixing rod 5 is movably engaged in the inside of the fixing seat 19, and second through holes 22 are arranged below the fixing rod 5 and on the outside of the fixing seat 19, and the fixing rod 5 and the fixing seat 19 are connected by a limiting rod 20, and the limiting rod 20 is respectively engaged with the second through hole 22 below the fixing rod 5 and the second through hole 22 on the outside of the fixing seat 19, and an external thread is arranged at the front end of the limiting rod 20, and a connecting nut 21 is threadedly connected to the front end of the limiting rod 20 for quick disassembly of the second brush 18.

A telescopic rod 17 is provided at the bottom of the cylinder 16, and the telescopic rod 17 is connected to the rear end of the second brush 18, and the telescopic rod 17 swings at the rear end of the second brush 18 through the connecting piece, so that the second brush 18 can be controlled to swing up and down.

[0025] Working principle: Loosen the connecting bolt 8 to disengage the connecting bolt 8 from the threaded hole 12 and the first through hole 13, and then the limit plate 14 can be pulled out from the first limit groove 10 and the second limit groove 15. Without the fixation of the limit plate 14, the bayonet 9 and the side plate 6 can quickly separate the first brush 7 from the front end of the dozer 2, which is convenient for disassembly. At the same time, by loosening the connecting nut 21, the front end of the limit rod 20 has no limit structure, and can be pulled out from between the fixing rod 5 and the fixing seat 19, so that the second brush 18 can be pulled out from the bottom of the fixing rod 5 without limit, which is convenient for disassembly.
