Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0016] Embodiment: As Figures 1-3 shown, the present invention provides a stirring mechanism for cement brick processing, including a base 1. One end of the upper surface of the base 1 is fixedly provided with an extension arm 11. Symmetrically distributed fixed rods 12 are fixedly provided in the middle of the outer surface of the extension arm 11. One end of the fixed rod 12 far from the extension arm 11 is fixedly connected to a stirring barrel 15. The upper end of the stirring barrel 15 is movably installed with a top cover 4. One side of the bottom end of the extension arm 11 close to the top cover 4 is fixedly provided with a gearbox 13. The bottom end of the extension arm 11 is rotatably connected to a first stirring shaft 2. The first stirring shaft 2 movably penetrates through the gearbox 13 and the top cover 4 and extends into the stirring barrel 15. The lower surface of the inner wall of the gearbox 13 is rotatably connected to a second stirring shaft 21. The second stirring shaft 21 movably penetrates through the gearbox 13 and the top cover 4 and extends into the stirring barrel 15. The lower end of the first stirring shaft 2 movably penetrates through the bottom end of the second stirring shaft 21. The lower end of the first stirring shaft 2 is fixedly provided with a reverse stirring blade 28. The lower end of the second stirring shaft 21 is fixedly provided with a forward stirring blade 27. The outer surface of the first stirring shaft 2 close to the upper surface of the inner wall of the gearbox 13 is fixedly provided with a first bevel gear 22. The outer surface of the second stirring shaft 21 close to the lower surface of the inner wall of the gearbox 13 is fixedly provided with a second bevel gear 23. A third bevel gear 25 is jointly meshed and connected between the first bevel gear 22 and the second bevel gear 23.
[0017] On one side of the outer surface of the gearbox 13 close to the extension arm 11, a first driving motor 24 is fixedly connected. The first driving motor 24 is fixedly connected with a driving shaft 26. The end of the driving shaft 26 is coaxially and fixedly arranged on the third bevel gear 25. By starting the first driving motor 24, the driving shaft 26 is driven to rotate, and then the third bevel gear 25 rotates, and then it is transmitted to the first bevel gear 22 and the second bevel gear 23. Due to their meshing mode, the rotation directions of the first bevel gear 22 and the second bevel gear 23 will be opposite, resulting in the stirring blades on the first stirring shaft 2 and the second stirring shaft 21 rotating in opposite directions, so as to cut and stir the raw materials in the stirring barrel 15 from different angles and directions, thus making the raw materials mixed more evenly.
[0018] At the top end of the extension arm 11, a support frame 14 is fixedly provided. The bottom end of the support frame 14 is fixedly installed on the outside of the stirring barrel 15. A vertically arranged threaded rod 31 is rotatably connected to the support frame 14. A transmission block 35 is threadedly installed on the outer surface of the threaded rod 31. The number of connecting rods 34 is two. One of the connecting rods 34 is fixedly arranged on the lower surface of the transmission block 35. The lower ends of the two connecting rods 34 extend into the stirring barrel 15 and are jointly fixedly connected with a scraper 3. The outer side of the scraper 3 is in contact with the inner wall of the stirring barrel 15 and the inner ring does not contact the end of the scraper 3. When the threaded rod 31 starts to rotate, the transmission block 35 also starts to move, thereby driving the connecting rod 34 to move, and then enabling the scraper 3 to effectively clean the inner wall of the stirring barrel 15, removing the materials on the inner wall, avoiding waste of raw materials, and simplifying the subsequent cleaning work.
[0019] On one side of the top end of the support frame 14 close to the threaded rod 31, a second driving motor 32 is fixedly installed. The driving end of the second driving motor 32 is fixedly installed with the top end of the threaded rod 31. When the second driving motor 32 is started, the threaded rod 31 starts to rotate, providing a power source for the scraper 3, so as to complete the work of removing the residual materials.
[0020] A limiting rod 33 is fixedly installed on the support frame 14. The limiting rod 33 is inserted through the transmission block 35. By using the limiting rod 33 to limit the moving direction of the transmission block 35, the transmission block 35 can only move up and down, and then the up and down movement of the scraper 3 is realized.
[0021] A feed inlet 41 is formed through the top cover 4. The raw materials can be poured into the stirring barrel 15 through the feed inlet 41, and the top cover 4 can prevent the raw materials from splashing out during the stirring process.
[0022] A rotating shaft 51 is rotatably installed at the bottom of the mixing barrel 15. One end of the rotating shaft 51 extends out of the mixing barrel 15 and is rotatably installed on the extension arm 11. A discharge plate 5 is fixedly installed on the side of the rotating shaft 51 away from the extension arm 11. The discharge plate 5 is movably clamped at the bottom of the mixing barrel 15. One end of the rotating shaft 51 away from the extension arm 11 passes through the mixing barrel 15 and is fixedly installed with a control rod 52. Rotating the control rod 52 can be used to control the flipping degree of the discharge plate 5, thereby adjusting the flow rate of the stirred material after mixing. By precisely controlling the angle of the discharge plate 5, the adjustment of the material flow rate can be achieved.
[0023] Symmetrically distributed insertion rods 53 are inserted through the outer surface of the discharge plate 5. A jack 54 is opened at the junction of the outer surface of the mixing barrel 15 and the discharge plate 5. The insertion rods 53 can be slidably inserted into the jack 54. Before the mixing work is carried out, it is necessary to check whether the insertion rods 53 have been correctly inserted into the jacks 54 to ensure that the discharge plate 5 is fixed in place to prevent accidental movement during the mixing process. After the mixing is completed, the insertion rods 53 are pulled out of the jacks 54. At this time, the rotation of the discharge plate 5 can be controlled by the control rod 52 to achieve discharging, ensuring the safety and efficiency of the mixing and discharging processes.
[0024] Working principle: First, it is necessary to check whether the discharge plate 5 at the bottom of the mixing barrel 15 has been inserted into the jack 54 through the insertion rods 53 and fixed. After confirmation, the raw materials for making cement bricks are poured into the mixing barrel 15 through the feed port 41. After the raw materials are poured in, when the first drive motor 24 is started, it drives the drive shaft 26 and the third bevel gear 25 fixed at its front end to start rotating. Since the third bevel gear 25 meshes with the first bevel gear 22 and the second bevel gear 23, the first bevel gear 22 and the second bevel gear 23 also start rotating, simultaneously driving the first mixing shaft 2 and the second mixing shaft 21 to start rotating, realizing that the forward mixing blades 27 and the reverse mixing blades 28 start rotating in opposite directions, so that the raw materials in the mixing barrel 15 are more evenly mixed;
[0025] After the mixing process is completed, the staff stops the first drive motor 24, which also stops the mixing work. Then, the insertion rods 53 are pulled out of the jacks 54, and by rotating the control rod 52, the discharge plate 5 starts to rotate and move to one side. In this way, the uniformly mixed substances in the mixing barrel 15 can fall out through the discharge plate 5 by gravity, greatly saving the time for the staff to discharge materials and improving work efficiency;
[0026] After the discharging is completed, some materials usually remain on the inner wall of the mixing barrel 15. At this time, the second driving motor 32 can be started to drive the threaded rod 31 to rotate. While the threaded rod 31 is rotating, it cooperates with the limiting rod 33 to drive the transmission block 35 to move up and down. This movement is transmitted through the connecting rod 34, and finally the scraper 3 moves from top to bottom on the inner wall of the mixing barrel 15 to clean the residual materials on the inner wall. This can save a large amount of raw material costs and facilitate the subsequent cleaning work by the staff.
[0027] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
