Technical Field
[0001] This utility model relates to the field of mixing technology for materials (sand, cement, and additives) used in hydraulic models, and in particular to a simple concrete mixer for use in hydraulic mud and sand models. Background Technology
[0002] During hydraulic model testing, for some hydraulic models with large space requirements, the use of mixers often leads to waste in the mixing and processing of hydraulic model materials due to site limitations and the difficulty of manual operation, increasing costs and causing time and labor costs. Moreover, existing mixers have low mixing efficiency, are time-consuming and labor-intensive, and have slow discharge rates. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a simple concrete mixing machine for use in hydraulic sediment models, so as to improve mixing efficiency and discharge rate.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a simple concrete mixer for use in hydraulic silt models, comprising a mixing tank, a mixing shaft arranged horizontally inside the mixing tank, a mixing rod arranged on the mixing shaft, a rotating shaft arranged vertically on each side of the mixing shaft, a spiral blade arranged on the surface of the rotating shaft, a horizontal bevel gear arranged at the top of the rotating shaft, the horizontal bevel gear meshing with the vertical bevel gear, one end of the vertical bevel gear being connected to one end of the rotating shaft, the other end of the rotating shaft being connected to the center of the driven wheel, one end of the mixing shaft being connected to the center of two driving wheels, a conveyor belt being wound between each driving wheel and the corresponding driven wheel, and a rotating handle being arranged at the other end of the mixing shaft.
[0005] The bottom of the mixing tank is slidably connected to a buffer rod via a buffer cylinder. A mounting plate is provided at the bottom of the buffer rod, and a buffer spring is provided between the mounting plate and the buffer cylinder.
[0006] The mounting plate is also equipped with a caster mechanism with brakes at the bottom.
[0007] The mounting plate is also provided with a sliding groove at the bottom, which slides in conjunction with the upper end of the positioning pile, and a tightening screw is provided on one side of the sliding groove.
[0008] The discharge port at the bottom of the mixing tank is also slidably connected to the discharge plate, and a handle is provided on one side of the discharge plate.
[0009] The bottom of the rotating shaft is limited to the bottom side of the mixing tank by a bearing, the top of the rotating shaft is limited to the top of the U-shaped frame by a bearing, and the bottom two sides of the U-shaped frame are fixed to the top side of the mixing tank.
[0010] The rotating shaft is confined within the limiting plate by a bearing, and the limiting plate is fixed to the top of the U-shaped frame.
[0011] This invention has a simple structure and is easy to use. It does not require an additional power supply. By combining horizontal and vertical stirring, it greatly increases the stirring efficiency and discharge rate, which is conducive to its widespread application. Furthermore, this invention can control the horizontal and vertical stirring mechanisms to operate simultaneously by rotating the crank handle, which greatly simplifies the structure and achieves the corresponding stirring and discharge effects.

[0015] The components include: mixing tank 1, mixing shaft 2, mixing rod 3, rotating shaft 4, spiral blade 5, horizontal bevel gear 6, vertical bevel gear 7, rotating shaft 8, driven wheel 9, driving wheel 10, conveyor belt 11, rotating handle 12, buffer cylinder 13, buffer rod 14, mounting plate 15, buffer spring 16, caster mechanism 17, chute 18, positioning post 19, tightening screw 20, discharge plate 21, handle 22, U-shaped frame 23, and limit plate 24. Detailed Implementation
[0016] like Figures 1 to 3 As shown, a simple concrete mixer for use in hydraulic silt models includes a mixing tank 1, a mixing shaft 2 horizontally arranged inside the mixing tank 1, a mixing rod 3 arranged on the mixing shaft 2, a rotating shaft 4 vertically arranged on each side of the mixing shaft 2, a spiral blade 5 arranged on the surface of the rotating shaft 4, a horizontal bevel gear 6 arranged at the top of the rotating shaft 4, the horizontal bevel gear 6 meshing with a vertical bevel gear 7, one end of the vertical bevel gear 7 being connected to one end of a rotating shaft 8, the other end of the rotating shaft 8 being connected to the center of a driven wheel 9, one end of the mixing shaft 2 being connected to the center of two driving wheels 10, a conveyor belt 11 being wound between each driving wheel 10 and the corresponding driven wheel 9, and a rotating handle 12 being arranged at the other end of the mixing shaft 2.
[0017] The bottom of the mixing tank 1 is slidably connected to the buffer rod 14 via a buffer cylinder 13. The bottom of the buffer rod 14 is provided with a mounting plate 15, and a buffer spring 16 is provided between the mounting plate 15 and the buffer cylinder 13. By setting the buffer spring 16, a buffer can be formed between the buffer cylinder 13 and the buffer rod 14, which can reduce the noise pollution generated by the mixing process.
[0018] The bottom of the mounting plate 15 is also equipped with a caster mechanism 17 with brakes.
[0019] The bottom of the mounting plate 15 is also provided with a sliding groove 18, which slides and engages with the upper end of the positioning pile 19. A tightening screw 20 is provided on one side of the sliding groove 18. With this design, when the mixing tank 1 moves to the corresponding position, the positioning pile 19 can be moved down and inserted into the soil, and then the tightening screw 20 can be tightened. This can further fix the position of the mixing tank 1 and prevent it from shaking during the mixing process.
[0020] The discharge port at the bottom of the mixing tank 1 is also slidably connected to the discharge plate 21, and a handle 22 is provided on one side of the discharge plate 21. With this design, the discharge plate 21 can be pulled out by the handle 22, and the size of the discharge port can be controlled according to the required amount of concrete, thereby controlling the amount of concrete discharged.
[0021] The bottom of the rotating shaft 4 is limited to the bottom side of the mixing tank 1 by a bearing, and the top of the rotating shaft 4 is limited to the top of the U-shaped frame 23 by a bearing. The bottom two sides of the U-shaped frame 23 are fixed to the top side of the mixing tank 1.
[0022] The rotating shaft 8 is limited within the limiting plate 24 by a bearing, and the limiting plate 24 is fixed to the top of the U-shaped frame 23.
[0023] The working principle of this embodiment is as follows:
[0024] First, move the mixing tank 1 to the location where the hydraulic model is to be built. When the mixing tank 1 is in the appropriate position, the positioning pile 19 can be moved down and inserted into the soil. Then, tighten the tightening screw 20 to further fix the position of the mixing tank 1 and prevent it from shaking during the mixing process. Then, pour the concrete raw materials such as cement, sand, gravel, water, and admixture into the mixing tank 1 in a certain proportion. Then, manually rotate the crank handle 12, which drives the mixing shaft 2 to rotate, and then causes the mixing rod 3 to agitate the materials. While the mixing shaft 2 is rotating, it will drive the two drive wheels 10 to rotate, thereby conveying the materials through the conveyor belt 11. The two driven wheels 9 rotate, which in turn causes the rotating shaft 8 to drive the vertical bevel gear 7 to rotate, and finally causes the horizontal bevel gear 6 to drive the rotating shaft 4 and the spiral blades 5 to rotate. When the spiral blades 5 rotate, the material can flow axially, which greatly increases the mixing efficiency. When the mixing is completed and the material needs to be unloaded, the discharge plate 21 can be pulled out by the handle 22. The size of the discharge port can be controlled according to the required amount of concrete, thereby controlling the amount of concrete discharged. At the same time, by rotating the crank 12 in the forward or reverse direction, the spiral blades 5 rotate to promote the material to move downward in the axial direction, which can greatly increase the discharge rate.
