[0022] The following will describe in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustration and explanation of the present disclosure, and are not intended to limit the present disclosure.

[0023] Example 1

[0024] As Figures 1-4 shown, a concrete preparation and mixing device proposed by the present utility model includes a tank body 1, an adjustment assembly, and a driving mechanism. A vertical cylinder 2 is rotatably penetrated through the tank body 1, a horizontal shaft 3 is rotatably penetrated through the vertical cylinder 2, and stirring plates 4 are arranged at both ends of the horizontal shaft 3 inside the tank body 1. An adjustment assembly is arranged inside the vertical cylinder 2, and the adjustment assembly has a limiting mechanism, and the two cooperate to adjust the set angle of the stirring plates 4. A driving mechanism for driving the vertical cylinder 2 and the stirring plates 4 to stir and mix the concrete raw materials inside is arranged at the top of the tank body 1.

[0025] Among them, multiple groups of horizontal shafts 3 are arranged vertically and equidistantly.

[0026] As Figure 1 shown, a hopper 5 is arranged at the top of the tank body 1, and a discharge pipe 6 is arranged at the bottom.

[0027] Among them, a solenoid valve is further arranged inside the discharge pipe 6 for conducting the discharge pipe 6 after the raw materials are mixed well.

[0028] As Figure 2 shown, the driving mechanism includes a motor 18, a gear a 19, and a gear b 20. The motor 18 is installed at the top of the tank body 1, and its output end is connected to the gear a 19. A gear b 20 is meshed on one side of the gear a 19, and the gear b 20 is installed on the vertical cylinder 2.

[0029] Among them, the motor 18 drives the gear a 19 to rotate, and the gear a 19 meshes with the gear b 20 to drive the vertical cylinder 2 and the stirring plates 4 to rotate synchronously, so that the stirring plates 4 stir and mix the raw materials in the tank body 1.

[0030] Example 2

[0031] As Figures 1-4As shown in the figure, a concrete preparation and mixing device proposed by the present utility model, on the basis of the above embodiment, this embodiment also details the specific structures of the adjustment component and the limiting mechanism, as well as the way they cooperate with each other.

[0032] As Figure 3 shown in the figure, the adjustment component includes a worm 7, a worm gear 8, a connecting shaft 9, a rotating shaft 10 and a handle 11. The worm 7 is rotatably arranged inside the vertical cylinder 2, and a worm gear 8 is meshed on one side of it. The worm gear 8 is installed on the horizontal shaft 3. A connecting shaft 9 is arranged at the top of the worm 7, and the top of the connecting shaft 9 extends above the vertical cylinder 2 to form a slot 12. A rotating shaft 10 is inserted into the slot 12, and the top of the rotating shaft 10 is connected with a handle 11.

[0033] As Figure 4 shown in the figure, convex blocks 13 are integrally formed on both sides of the inner wall of the slot 12, and rectangular grooves 14 cooperating with the convex blocks 13 are formed on both sides of the rotating shaft 10.

[0034] With the cooperation of the convex blocks 13 and the slot 12, when the handle 11 is used to drive the rotating shaft 10 to rotate, it will drive the worm 7 to rotate synchronously through the connecting shaft 9. When the worm 7 rotates, it meshes with the worm gear 8, and the meshing force drives the horizontal shaft 3 to rotate, so that the angle of the stirring plate 4 can be adjusted.

[0035] As Figure 4 shown in the figure, the limiting mechanism includes a tension spring 15 and a positioning shaft 16. The tension spring 15 is arranged inside the slot 12, its bottom end is connected with the bottom of the slot 12, and its top end is connected with the rotating shaft 10. A plurality of groups of positioning holes 17 arranged around the circumference of the rotating shaft 10 are formed on the upper end surface of the vertical cylinder 2. A positioning shaft 16 is connected to the bottom of the handle 11, and the positioning shaft 16 is inserted into the corresponding positioning hole 17.

[0036] The tension spring 15 generates a downward elastic force on the rotating shaft 10, and then synchronously acts on the handle 11 on the rotating shaft 10, so that the positioning shaft 16 at the bottom of the handle 11 is inserted into the corresponding positioning hole 17. When the stirring mechanism is running, the handle 11 will not rotate by itself under the action of the tension spring 15, ensuring the stability of the setting of the adjustment component. When the angle of the stirring plate 4 needs to be adjusted, first, the rotational limit of the handle 11 needs to be released, that is, manually pull the handle 11 upward. During the upward process, on the one hand, the handle 11 drives the tension spring 15 to stretch through the rotating shaft 10, so that it undergoes elastic deformation. On the other hand, the handle 11 drives the positioning shaft 16 to disengage from the positioning hole 17, and then a rotational force can be applied to the handle 11. When the adjustment is completed, release the upward pulling force applied to the handle 11, and under the reset action of the tension spring 15, drive the handle 11 to descend through the rotating shaft 10, so that the positioning shaft 16 on it is correspondingly inserted into the positioning hole 17.

[0037] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those skilled in the art to which it pertains.
