Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a limestone block grinding device, including a base box 1, a box door 2, a transmission rod 3, a collection frame 4, rollers 5, a sieve frame 6, a support 7, a double-headed motor 8, a reciprocating screw 9, a screw slider 10, a transmission frame 11, a grinding box 12, a feeding pipe 13, a grinding wall 14, a drive rod 15, a secondary bevel gear 16, a grinding pestle 17, a base 18, a drive mechanism 19, a drive rod 1901, and a main bevel gear 1902. A box door 2 is installed at one end of the base box 1, and a transmission rod 3 is movably connected to the other end of the base box 1. A collection frame 4 is fixedly connected to the end of the transmission rod 3, and a sieve frame 6 is slidably installed on the inner wall of the collection frame 4. A support 7 is fixedly connected to the end face of the base box 1, and a double-headed motor 8 is installed on the end face of the upper surface of the base box 1. A reciprocating screw 9 is fixedly connected to the end of the output shaft, and a screw slider 10 is installed on the outer wall of the reciprocating screw 9. A transmission frame 11 is fixedly connected to the lower surface of the screw slider 10. The transmission frame 11 is fixedly connected to the transmission rod 3. A grinding box 12 is fixedly installed on the upper surface of the bottom box 1. A feeding pipe 13 is installed on the side of the upper surface of the grinding box 12. A grinding wall 14 is fixedly installed on the inner wall of the grinding box 12. An active rod 15 is movably connected to the upper inner wall of the grinding box 12. The active rod 15 is located on one side of the feeding pipe 13. At the same time, a secondary bevel gear 16 and a grinding pestle 17 are fixed at the upper and lower ends of the active rod 15, respectively. A base 18 is fixedly connected to the upper surface of the grinding box 12. A drive mechanism 19 is installed on the inner wall of the base 18. The drive mechanism 19 drives the secondary bevel gear 16 to rotate.

[0022] Specifically, the transmission rod 3 and the base box 1 form a sliding structure, and the transmission rod 3 and the transmission frame 11 are connected by bolts, which facilitates the sliding of the transmission rod 3 relative to the base box 1, thereby driving the collection frame 4 and the screen frame 6 to move back and forth to screen the powder, and also facilitates the connection or disconnection of the transmission rod 3 and the transmission frame 11.

[0023] In this embodiment, rollers 5 are installed on the lower surface and the outer side wall of the collection frame 4, and the rollers 5 are in contact with the bottom box 1, so that when the collection frame 4 moves, the collection frame 4 drives the rollers 5 to move relative to the bottom box 1, thereby making the collection frame 4 move stably.

[0024] Based on the above embodiments, in a preferred embodiment, the drive mechanism 19 includes a drive rod 1901 and a main bevel gear 1902. The drive rod 1901 is rotatably mounted on the inner wall of the base 18, and the end of the drive rod 1901 is fixedly connected to the main bevel gear 1902. The main bevel gear 1902 and the secondary bevel gear 16 mesh with each other, so that the dual-head motor 8 can drive the reciprocating screw 9 to rotate through the drive mechanism 19.

[0025] Furthermore, the outer wall of the end of the drive rod 1901 away from the main bevel gear 1902 is connected to the outer wall of the output shaft of the dual-head motor 8 through a sprocket mechanism, which facilitates the dual-head motor 8 to drive the drive rod 1901 to rotate relative to the base 18 through the sprocket mechanism, so that the drive rod 1901 drives the main bevel gear 1902, thereby allowing the main bevel gear 1902 to drive the secondary bevel gear 16 and cause the drive rod 15 to rotate.

[0026] Specifically, the bracket 7 and the reciprocating screw 9 are rotatably connected, and the drive rod 15 is rotatably mounted on the grinding box 12, which facilitates the stable rotation of the reciprocating screw 9 by the double-headed motor 8, and facilitates the rotation of the drive rod 15 relative to the grinding box 12, thereby driving the grinding pestle 17 to process the limestone block.

[0027] Working principle: When using this limestone grinding device, firstly as follows... Figure 1-4 As shown, the user adds the limestone blocks to be processed into the grinding box 12 through the feeding pipe 13. Then, the user starts the dual-head motor 8. The dual-head motor 8 then drives the drive rod 1901 to rotate relative to the base 18 via the sprocket mechanism. Subsequently, the drive rod 1901 drives the main bevel gear 1902 to rotate, which in turn drives the secondary bevel gear 16 to rotate. The secondary bevel gear 16 then drives the drive rod 15 to rotate relative to the grinding box 12. The drive rod 15 then drives the grinding pestle 17 to rotate. At this time, the rotating grinding pestle 17, in conjunction with the grinding wall 14, grinds the limestone blocks. The processed limestone powder then falls from the grinding box 12 into the screen frame 6. With the start of the dual-head motor 8, the dual-head motor 8 drives the reciprocating screw 9 to rotate relative to the support 7. Then, the screw slider 10 moves along the reciprocating screw 9... The device moves back and forth, then the lead screw slider 10 drives the transmission frame 11 to move back and forth, then the transmission frame 11 drives the transmission rod 3 to move back and forth, and then the transmission rod 3 drives the collection frame 4 to move back and forth. At this time, the collection frame 4 drives the roller 5 to move relative to the bottom box 1, and at the same time the collection frame 4 drives the screen frame 6 to move back and forth, so that the screen frame 6 can screen the limestone powder. After the limestone is processed, the user turns off the double-head motor 8, then the user removes the bolts between the transmission rod 3 and the transmission frame 11, then the user opens the box door 2 and pulls out the collection frame 4 in the bottom box 1, then the user removes the screen frame 6 on the collection frame 4 and pours out the limestone powder in the collection frame 4, thus completing the removal of the screened powder. Therefore, the device is convenient for screening the ground limestone powder, thus ensuring the quality of the limestone powder processed by the device.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
