[0002] Cold patch is a material used in pavement maintenance and construction, typically composed of crushed stone, sand, cement, and other additives. It is suitable for temporary repairs and small-scale projects. Cold patch generally has a lower construction cost and a shorter setting time. Mixing is required to ensure that the various raw materials are thoroughly mixed to obtain a uniform composition.

[0003] On-site cold patch material mixing equipment enables on-site customization and just-in-time production, improving construction efficiency and flexibility. Existing mixing equipment primarily consists of a motor-driven mixing rod that rotates fixedly within a tank, ensuring uniform mixing of the cold patch material. Material ratios and formulations can be adjusted promptly based on specific project requirements to ensure the production of qualified cold patch material. Furthermore, the use of on-site mixing equipment reduces material transportation costs and reliance on pre-cold patch material, helping to reduce carbon emissions and resource waste.

At the same time, the fixed-position mixing rod will cause some areas of the mixer to wear faster, while other areas will wear slower, accelerating the damage and maintenance cycle of the equipment. Therefore, a cold patch material on-site mixing device is proposed to solve the above problems. Summary of the Invention

A fixing rod 24 is fixedly connected to the top of the inner wall of the mixing tank 2. One side of the outer wall of the fixing rod 24 is rotatably connected to a gear 12. One side of the outer wall of the gear 12 is fixedly connected to a limit block 2 11. One side of the outer wall of the limit block 19 is rotatably connected to a connecting rod 10.

A control valve 17 is fixedly connected to the bottom of the mixing tank 2. A mixing assembly is provided on the outer wall of the gear column 13. The mixing assembly is used to mix the cold patch material inside the mixing tank 2.

[0034] Specifically, the cold patch material to be mixed is transported to the inside of the mixing tank 2 through the feed pipe 1, and the motor 5 is started to drive the worm 7 to rotate, thereby driving the drive gear 6 to rotate. Since the outer wall of the gear 2 14 is meshed with the outer wall of the drive gear 6, the rotation of the drive gear 6 drives the rotation of the gear 2 14. Since the outer wall of the tooth column 13 is provided with a protrusion, the rotation of the gear 2 14 drives the rotation of the tooth column 13, further driving the rotation of the mixing column 15. The rotation of the mixing column 15 drives the rotation of the mixing rod 16. Since the outer wall of the worm 7 is meshed with the outer wall of the worm wheel 8, the rotation of the worm 7 drives the rotation of the worm wheel 8, thereby This drives the limit block 19 to rotate, and the limit block 19 drives the connecting rod 10 to do crank motion, and the connecting rod 10 drives the limit block 2 11 to move. Since the limit block 2 11 is longer, the connecting rod 10 can only drive the limit block 2 11 to swing up and down, thereby driving the gear 12 to rotate back and forth, and further driving the gear column 13 to do up and down reciprocating motion. The mixing rod 16 reciprocates up and down while rotating, so that the cold patch material inside the mixing tank 2 is mixed more fully and evenly. After the mixing is completed, the control valve 17 is opened, so that the mixed cold patch material is output from the mixing tank 2, completing the sufficient mixing of the cold patch material.

[0035] Reference Figure 2 The mixing assembly includes a mixing column 15 and a mixing rod 16. The outer wall of the mixing column 15 is fixedly connected to the outer wall of the tooth column 13, and one side of the outer wall of the mixing rod 16 is fixedly connected to the outer wall of the mixing column 15;

[0036] Specifically, the rotation of the tooth column 13 drives the mixing column 15 to rotate, thereby driving the mixing rod 16 to rotate. At the same time, the tooth column 13 makes an up and down reciprocating motion, driving the mixing column 15 and the mixing rod 16 to make an up and down reciprocating motion, so that the cold patch material inside the mixing tank 2 is mixed more fully, solving the problem of insufficient mixing of the mixing rod 16 in a fixed position of the cold patch material on-site mixing device, and improving the production quality of the product.

[0037] Reference Figure 4 and Figure 5 The outer wall of the mixing tank 2 is fixedly connected with a fixing ring 25, the inside of the fixing ring 25 is fixedly connected with a universal wheel 18, the top of the fixing ring 25 is fixedly connected with the outer shell 4, the inner wall of the outer shell 4 is slidably connected with a sliding column 21, the top of the sliding column 21 is fixedly connected with a push handle 3, the inner wall of the push handle 3 is slidably connected with a pressing block 19, a spring 20 is provided between the pressing block 19 and the sliding column 21, one end of the spring 20 is fixedly connected to the bottom of the pressing block 19, and the other end of the spring 20 is fixedly connected to the top of the sliding column 21, and one side of the outer wall of the sliding column 21 is rotatably connected with a card column 22;

[0038] The spring 20 makes the push block 19 always on the surface of the push handle 3, and the slide post 21 moves upward, driving the post 22 to rotate, so that the post 22 reaches the new latch position and is locked again, achieving the locking effect. The latch position is provided with multiple, and the height of the push handle 3 can be set according to different pushing requirements, completing the extension of the push handle 3. The position of the outer shell 4 is arranged at a certain tilt angle with the fixing ring 25, which makes it easier to push the device. Pushing the push handle 3 drives the universal wheel 18 to rotate, completing the pushing of the device to different working sites, thereby improving the portability of the device.

[0039] Working principle: First, press the button 19 to compress the spring 20, and at the same time, the slide 21 moves downward, thereby driving the card column 22 to rotate, causing one end of the card column 22 to leave the bayonet, and then pull the push handle 3 upward to drive the slide column 21 to slide on the inner wall of the outer shell 4. When the push handle 3 is pulled to the appropriate position, release the button 19, driving the spring 20 to extend, so that the button 19 returns to the initial position before pressing, and at the same time, the slide 21 moves upward, driving the card column 22 to rotate, so that the card column 22 reaches the new bayonet position and is re-engaged, completing the extension of the push handle 3, and pushing the push handle 3 to the site where the materials need to be mixed, driving the universal wheel 18 to rotate.

Since the outer wall of worm 7 is meshed with the outer wall of worm wheel 8, the rotation of worm 7 drives the rotation of worm wheel 8, thereby driving the rotation of limit block 1 9, and limit block 1 9 drives connecting rod 10 to do crank motion, and connecting rod 10 drives limit block 2 11 to move. Since the length of limit block 2 11 is long, connecting rod 10 can only drive limit block 2 11 to swing up and down, thereby driving gear 12 to rotate back and forth, and further driving tooth column 13 to do reciprocating motion up and down. After mixing is completed, control valve 17 is opened, so that the cold patch material after mixing is output from mixing tank 2, completing the full mixing of the cold patch material.
