Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a road surface polymer slurry preparation and mixing device. Background Technology

[0002] Polymer slurry for road surfaces is a special material used for road repair and maintenance, typically composed of polymer resins, fillers, and additives. In road construction, polymer slurry can be used to repair cracks and potholes, fill uneven areas on the road surface, repair damaged areas, and improve the overall performance of the road surface.

[0003] A search revealed a utility model patent with patent authorization announcement number CN215842749U, which discloses a mixing device for slurry preparation, including a mixing cylinder mechanism. The mixing cylinder mechanism includes a mixing cylinder body, an elevated support foot installed on the bottom of the mixing cylinder body, a discharge pipe installed on the lower side of the mixing cylinder body, a stepped structure on the inner wall of the mixing cylinder body, and feed pipes installed on the upper and middle sides of the mixing cylinder body. A sealed top cover is connected to the top of the mixing cylinder body.

[0004] However, existing road surface polymer slurry preparation and mixing devices have relatively fixed mixing components, which can easily lead to slurry stratification and uneven mixing. In addition, the machine is quite heavy, requiring additional hoisting equipment when changing to different construction sites, which is quite troublesome. Utility Model Content

[0005] The purpose of this invention is to provide a road surface polymer slurry preparation and mixing device, which solves the problem that the existing road surface polymer slurry preparation and mixing devices do not mix evenly enough, and also solves the problem that the whole machine is inconvenient to change construction sites.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a road surface polymer slurry preparation and mixing device, comprising a mixing tank, a movable displacement mechanism at the bottom of the mixing tank, a bracket welded to the top of the mixing tank, a top seat fixedly connected to the end of the bracket, the top seat being located above the mixing tank, a drive shaft mounted inside the top seat via bearings, the drive shaft penetrating the top seat, a crankshaft slidably sleeved on the lower section of the drive shaft, main stirring rods welded to both the upper and lower sections of the crankshaft, a secondary stirring rod fixedly connected to the middle section of the crankshaft, an L-shaped rod fixedly connected to the end of the crankshaft, and an inclined seat fixedly connected to the bottom inner side of the mixing tank, the end of the L-shaped rod abutting against the inclined surface of the inclined seat.

[0007] Preferably, multiple supports are provided, and these supports are arranged in a circular array along the circumference of the mixing tank. The supports provide support for the top seat.

[0008] Preferably, a scraper is fixedly connected to the end of the auxiliary stirring rod, and the scraper contacts the inner wall of the mixing tank. The scraper can rotate with the crankshaft, thereby cleaning the inner wall of the mixing tank and preventing slurry from adhering to it.

[0009] Preferably, a square rod is fixedly connected to the upper end of the crankshaft, and the square rod is slidably connected to the drive shaft. A spring is sleeved on the outer side of the square rod, one end of the spring is fixedly connected to the drive shaft, and the other end of the spring is fixedly connected to the inner surface of the crankshaft. The square rod and spring configuration not only allow the crankshaft to rotate with the drive shaft, but also allow the crankshaft to extend and retract axially within the drive shaft.

[0010] Preferably, a driven gear is fixedly connected to the top of the drive shaft, and a motor is fixedly mounted on the upper end of the top seat. A drive gear is fixedly connected to the end of the output shaft of the motor, and the drive gear meshes with the driven gear. The motor drives the drive gear to rotate, and the drive gear, in turn, drives the drive shaft to rotate through its engagement with the driven gear, thus providing a power source for the rotation of the drive shaft.

[0011] Preferably, a discharge pipe is connected to the bottom of the mixing tank, and a valve is installed on the discharge pipe. The discharge pipe facilitates the discharge of the mixed slurry from the mixing tank.

[0012] Preferably, the moving and shifting mechanism includes four hollow legs fixedly connected to the bottom edge of the mixing tank. Each hollow leg has a sliding column slidably connected inside. A heavy-duty caster wheel is mounted on the lower end of each sliding column. A connecting block is fixedly connected to the middle section of the column, penetrating the hollow leg and slidably connected to it. A linkage seat is fixedly connected to the end of the connecting block. A hydraulic cylinder is fixedly installed at the bottom center of the mixing tank, and the piston rod of the hydraulic cylinder is fixedly connected to the linkage seat. This moving and shifting mechanism facilitates overall moving and shifting.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When the drive shaft rotates, the L-shaped rod is periodically pressed by the inclined surface of the inclined seat, which allows the crankshaft to extend and retract axially. This drives the main and auxiliary stirring rods to rotate while also extending and retracting axially, thereby expanding the stirring range and improving the efficiency and uniformity of slurry mixing.

[0015] 2. This utility model sets a moving and switching mechanism at the bottom of the mixing tank. The hydraulic cylinder controls the lifting and lowering of four sliding columns synchronously through the linkage seat, so as to realize the rapid retraction and extension of heavy-duty universal wheels. This makes the device both mobile flexibility and operational stability, and facilitates switching between multiple construction sites. Attached Figure Description

[0022] Please see Figures 1-4A road surface polymer slurry preparation and mixing device includes a mixing tank 1. A bracket 3 is welded to the top of the mixing tank 1. Multiple brackets 3 are arranged in a circular array along the circumference of the mixing tank 1. The brackets 3 support a top seat 4. The top seat 4 is fixedly connected to the end of each bracket 3 and is located above the mixing tank 1. A drive shaft 5 is mounted inside the top seat 4 via bearings and passes through the top seat 4. A crankshaft 6 is slidably sleeved on the lower section of the drive shaft 5. A square rod 10 is fixedly connected to the upper end of the crankshaft 6 and slidably connected to the drive shaft 5. A spring 11 is sleeved on the outer side of the square rod 10. One end of the spring 11 is fixedly connected to the drive shaft 5, and the other end is fixedly connected to the inner surface of the crankshaft 6. The square rod 10 and spring 11 allow the crankshaft 6 to rotate with the drive shaft 5 and also allow the crankshaft 6 to extend and retract axially within the drive shaft 5. A discharge pipe 17 is connected to the bottom of the mixing tank 1, and a valve is installed on the discharge pipe 17. The discharge pipe 17 facilitates the discharge of the mixed slurry from the mixing tank 1.

[0023] Please see Figures 3-4 The crankshaft 6 has main stirring rods 7 welded to both its upper and lower sections. A secondary stirring rod 8 is fixedly connected to the middle section of the crankshaft 6, and a scraper 9 is fixedly connected to the end of the secondary stirring rod 8, contacting the inner wall of the mixing tank 1. The scraper 9 rotates with the crankshaft 6, cleaning the inner wall of the mixing tank 1 and preventing slurry from adhering to it. An L-shaped rod 16 is fixedly connected to the end of the crankshaft 6, and a sloping seat 15 is fixedly connected to the bottom inner side of the mixing tank 1. The end of the L-shaped rod 16 abuts against the sloping surface of the sloping seat 15. A driven gear 12 is fixedly connected to the top of the drive shaft 5, and a motor 13 is fixedly mounted on the upper end of the top seat 4. A drive gear 14 is fixedly connected to the end of the output shaft of the motor 13, meshing with the driven gear 12. The motor 13 drives the drive gear 14 to rotate, which in turn drives the drive shaft 5 to rotate through its engagement with the driven gear 12, providing a power source for the rotation of the drive shaft 5.

[0024] Please see Figures 1-3 A moving and shifting mechanism 2 is provided at the bottom of the mixing tank 1. The moving and shifting mechanism 2 includes four hollow legs 21 fixedly connected to the bottom edge of the mixing tank 1. Each hollow leg 21 has a sliding column 22 slidably connected inside. A heavy-duty universal wheel 23 is installed at the lower end of the sliding column 22. A connecting block 24 is fixedly connected to the middle section of the column 22. The connecting block 24 passes through the hollow leg 21 and is slidably connected to the hollow leg 21. A linkage seat 25 is fixedly connected to the end of the connecting block 24. A hydraulic cylinder 26 is fixedly installed at the center of the bottom of the mixing tank 1. The end of the piston rod of the hydraulic cylinder 26 is fixedly connected to the linkage seat 25. The moving and shifting mechanism 2 facilitates the overall moving and shifting of the mixing tank.

[0025] The specific implementation process of this utility model is as follows: In use, firstly, the hydraulic cylinder 26 synchronously controls the lifting and lowering of the four sliding columns 22 through the linkage seat 25, until the heavy-duty universal wheels 23 at the bottom of the sliding columns 22 extend into the hollow legs 21, until the heavy-duty universal wheels 23 touch the ground, thus giving the whole unit mobility. Then, the position is moved by the heavy-duty universal wheels 23. After moving to the predetermined position, the hydraulic cylinder 26 drives the heavy-duty universal wheels 23 to retract into the hollow legs 21. The whole unit is then supported by the hollow legs 21, and its stability is not affected in any way. Then, the slurry is put into the mixing tank 1, and then... The electric motor 13 drives the drive gear 14 to rotate, which in turn drives the drive shaft 5 to rotate through its engagement with the driven gear 12. The drive shaft 5 then drives the crankshaft 6 to rotate through the square rod 10. The crankshaft 6 simultaneously drives the main stirring rod 7 and the auxiliary stirring rod 8 to mix the slurry. At the same time, the L-shaped rod 16 is periodically pressed against the inclined surface of the inclined seat 15, which allows the crankshaft 6 to extend and retract axially. This allows the main stirring rod 7 and the auxiliary stirring rod 8 to rotate while also extending and retracting axially, thereby expanding the mixing range and improving the efficiency and uniformity of the slurry mixing. The mixed slurry can be discharged from the discharge pipe 17.
