Description

Technical Field

[0001] This utility model relates to a model device, specifically a millstone pushing model, used to demonstrate the traditional millstone pushing process, and has educational and entertainment value. Background Technology

[0002] Traditional milling models often lack interactivity, failing to provide users with an intuitive understanding of the milling principles. For example, existing models often cannot simulate realistic milling actions and grain grinding processes, and the transmission components are often concealed, hindering teaching and demonstration. Therefore, a more refined milling model is needed that can demonstrate the entire milling process through manual operation, enhancing the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a milling model that simulates real milling action through the design of a puppet, millstone, and transmission components. It allows users to drive the millstone to rotate by operating a knob and see the grains flowing out of the millstone, thus vividly demonstrating the milling principle and grain grinding process.

[0004] The technical solution of this utility model is as follows:

[0005] A grinding wheel model includes a doll, a grinding rod, a base, a circular upper grinding wheel, a circular lower grinding wheel, a pair of toothed transmission components, and a knob. The base has a cavity. The lower end of the shaft of one toothed transmission component is vertically hinged to a vertical blind hole on the bottom surface of the cavity. The upper end of the shaft of this toothed transmission component passes through the center hole of the circular lower grinding wheel, which is fixed above the cavity, and is coaxially fixed to the bottom of the circular upper grinding wheel. The shaft of the other toothed transmission component extends horizontally outward through the side wall of the cavity, forming a hinge. The extended end of this shaft is fixedly connected to the knob. The two toothed transmission components engage in a meshing transmission within the cavity. Rotating the knob around a horizontal axis, via the meshing transmission of the pair of toothed transmission components, drives the upper grinding wheel to rotate around a vertical axis.

[0006] Furthermore, the circular upper grinding disc has an open-top hollow structure with a circular through hole at the bottom of the inner cavity. The bottom of the inner cavity forms a downward slope towards the circular through hole, which facilitates the flow of materials to the through hole.

[0007] Furthermore, the upper surface of the circular lower grinding disc has a circular through hole extending to the side of the lower grinding disc, allowing material to flow out from the through hole.

[0008] Furthermore, the upper and lower circular grinding discs are coaxial, and the circular through holes at the bottom of the upper grinding disc and the circular through holes on the upper surface of the lower grinding disc are of equal size and the distance from their centers to the axes of the two grinding discs is equal, ensuring that the material is smoothly transferred when the grinding discs rotate.

[0009] Furthermore, the bottom of the circular lower grinding disc is provided with a radially coaxial and bottom-equivalent annular ramp. A surrounding wall is provided around the annular ramp. The annular ramp starts at the outlet of the through hole on the side of the circular lower grinding disc and ends at the gap in the surrounding wall, which is used to guide the material outflow.

[0010] Furthermore, a window is provided on the cavity wall of the base to facilitate observation of the movement of the internal transmission components.

[0011] Furthermore, the circular upper grinding disc is provided with a removable upper cover.

[0012] Furthermore, the doll stands fixedly on the base plate facing the cavity on the base. The front ends of the doll's two arms are hinged to the two ends of the handle of the grinding rod. The downward-facing column at the front end of the grinding rod is hinged to the vertical hole set on the upper edge of the circular upper grinding disc, so that the doll's arms move with the grinding rod to simulate the grinding action.

[0013] Furthermore, the pair of toothed transmission components are bevel gears or worm gears.

[0014] The beneficial effects of this utility model are:

[0015] A knob operates to drive a toothed transmission mechanism, which rotates the upper grinding disc. The upper grinding disc then drives a grinding rod, which in turn moves the puppet's arms and body to simulate grinding motions, increasing vividness and interactivity. The through-holes and ramps in the grinding disc allow for the simulation of grain grinding and flow, further enhancing vividness and interactivity. A window in the cavity allows for easy observation of the internal transmission mechanism, improving the display effect and educational value. The overall structure is compact, easy to install and operate, and suitable for educational, demonstration, and entertainment purposes. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] like Figures 1 to 7 As shown, the grinding model includes a doll 1, a grinding rod 2, a base 3, a circular upper grinding disc 4, a circular lower grinding disc 5, a pair of toothed transmission components 6 and 7, and a knob 8.

[0025] A cavity 31 is provided on the base 3. The lower end of the shaft of the toothed transmission member 6 is hinged in a vertical blind hole 32 on the bottom surface of the cavity 31, and its upper end passes through the center hole of the lower circular grinding disc 5 and is coaxially fixed to the bottom of the upper circular grinding disc 4. The lower circular grinding disc 5 is fixed above the cavity 31. The shaft of the toothed transmission member 7 passes horizontally outward through the side wall hole 311 of the cavity 31 to form a hinge, and the extended end of the shaft is fixedly connected to the knob 8. The toothed transmission members 6 and 7 form a meshing transmission within the cavity 31. For example, the toothed transmission members 6 and 7 can be bevel gears, worm gears, or similar transmission components. When the user rotates the knob 8 around the horizontal axis, the toothed transmission member 7 drives the toothed transmission member 6, thereby causing the upper circular grinding disc 4 to rotate around the vertical axis.

[0026] The upper circular grinding disc 4 has a hollow, open-top structure with a circular through-hole 41 at the bottom of its inner cavity. The bottom of the inner cavity slopes downwards towards this through-hole 41, facilitating the flow of materials such as mung beans into the through-hole 41 under gravity. The lower circular grinding disc 5 has a circular through-hole 51 extending through to its side 52. The upper and lower circular grinding discs 4 and 5 are coaxially mounted. The circular through-holes 41 and 51 are of equal size and equidistant from their centers to the grinding disc axis. Thus, when the upper grinding disc 4 rotates, the through-holes 41 and 51 periodically align, allowing material to fall from the through-hole 41 into the through-hole 51.

[0027] A circular lower grinding disc 5 has a radially arranged annular ramp 53 at its bottom periphery. The annular ramp 53 is coaxial with the circular lower grinding disc 5 and has the same bottom. A surrounding wall 54 is provided around its outer periphery. The annular ramp 53 starts at the outlet of the through hole on the side 52 of the circular lower grinding disc and ends at the notch 55 in the surrounding wall. After the material flows out of the through hole 52, it slides down along the annular ramp 53 and is discharged from the notch 55, simulating the product collection process after grinding.

[0028] A window 312 is provided on the wall of the base cavity 31 to facilitate users to observe the meshing and movement of the internal toothed transmission components 6 and 7, thereby enhancing the educational and fun aspects.

[0029] The circular upper grinding disc 4 is equipped with a removable upper cover 44, which can be opened to put in materials and facilitate the user to observe the flow of materials, while the cover can prevent materials from spilling.

[0030] The doll 1 stands fixedly on the base plate of the base 3, facing the base cavity 31. The legs 12 and arms 11 of the doll 1 are movable relative to the body, and the front ends of the hands 111 of the two arms are hinged to the two ends of the handle 22 of the grinding rod 2. The downward-facing column 21 of the front end of the grinding rod 2 is hinged to the vertical hole 43 provided on the upper edge of the circular upper grinding disc 4. When the upper grinding disc 4 rotates, the grinding rod 2 moves accordingly, causing the arms 11 of the doll 1 to swing, simulating the grinding action.

[0031] During operation, the user turns knob 8, which, through the transmission of toothed drive components 7 and 6, causes the upper grinding disc 4 to rotate. The pusher rod 2 drives the puppet's arm to move, presenting a vivid grinding scene. The user can put materials such as mung beans into the hollow cavity of the upper grinding disc 4, and the material flows along the slope 42 to the through hole 41. When the through hole 41 aligns with the through hole 51 of the lower grinding disc, the material falls into the through hole 51, flows out from the side 52 to the circular ramp 53, and finally exits from the notch 55, completely simulating the grinding process.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
