[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Reference Figure 1-3This utility model provides an embodiment of a screening machine for dry-mixed mortar production, comprising a support 1, a box 5 at the top of the support 1, a vibration motor at the bottom of the box 5, which vibrates multiple screen plates 4; connecting blocks 3 are fixedly connected to the bottom of both ends of the box 5; three screen plates 4 are arranged vertically inside the box 5, with the upper screen plate 4 having a larger aperture than the lower screen plate 4; multiple discharge ports 8 are fixedly connected to the front end of the box 5; a movable plate 12 is fitted on the outer wall of the discharge port 8; by moving the movable plate 12 to the front end and contacting the guide groove 7, the guide groove 7 is always in contact with the rotating block 14, thus ensuring the stability of the guide groove 7; insert rods 10 are provided at both ends of the movable plate 12; by inserting the insert rods 10 into the limiting plate 11, the guide groove 7 is connected to the discharge port 8; the rear end of the insert rod 10 is fixedly connected to... A fixing block 9 is fixedly connected to the outer wall of the box body 5. A through groove is opened on the outer wall of the insertion rod 10. A fixing rod is fixedly connected to the inner wall of the through groove. Two rotating blocks 14 are rotatably connected to the outer wall of the fixing rod. The rotating blocks 14 can rotate on the outer wall of the fixing rod and can rotate into and out of the through groove. The bottom end of the top rotating block 14 is fixedly connected to the limiting cylinder 16. The bottom of the limiting cylinder 16 is slidably connected to the limiting cylinder 2 17. By setting the limiting cylinder 16 and the limiting cylinder 2 17, the rotation angle of the two rotating blocks 14 can be limited to avoid the rotation angle of the two rotating blocks 14 being too large or too small. The bottom of the limiting cylinder 2 17 is fixedly connected to the top of the bottom rotating block 14. The front end of multiple discharge ports 8 is provided with a guide groove 7. The lengths of the multiple guide grooves 7 are different. The length of the upper guide groove 7 is greater than the length of the lower guide groove 7. The guide grooves 7 can guide the screened dry-mixed mortar to different collection buckets.

[0024] Reference Figure 2-4The bracket 1 has a spring 2 at its top, with one end connected to the top of the bracket 1 and the other end connected to the outer wall of the connecting block 3. The spring 2 reduces the shaking amplitude of the housing 5 during operation. A spring 13 is fitted onto the outer wall of the insertion rod 10, with one end connected to the front end of the fixing block 9 and the other end connected to the rear end of the moving plate 12. The spring 13 pushes the moving plate 12 towards one side of the guide groove 7, ensuring the guide groove 7 remains in contact with the rotating block 14, thus preventing the limiting piece 11 from moving on the outer wall of the insertion rod 10. A spring 15 is located on the adjacent side of the two rotating blocks 14, with one end connected to the bottom of the top rotating block 14 and the other end connected to the top of the bottom rotating block 14. The spring 15 automatically pushes the rotating block 14 out of the through groove, allowing the rotating block 14 to limit the position of the limiting piece 11. Both ends of the guide groove 7 are fixedly connected to limiting plates 11. The middle of the limiting plate 11 has a limiting hole that matches the size of the insertion rod 10. By fitting the limiting plate 11 onto the outer wall of the insertion rod 10, the guide groove 7 can be installed at the front end of the discharge port 8. The rear top of the box body 5 is fixedly connected to the feeding port 6. The feeding port 6 allows the feeding mechanism to easily transport dry-mixed mortar into the box body 5.

[0025] Working Principle: First, the dry-mixed mortar is fed into the box 5 by the feeding mechanism. A vibrating motor vibrates the screen plate 4, allowing the mortar to be screened through multiple screen plates with different apertures. The screened mortar is then discharged from the box 5 through the discharge port 8 and guided by the guide trough 7 into different collection bins. When cleaning the inner wall of the guide trough 7 is required, two rotating blocks 14 are pressed into the insertion rod 10, compressing the spring 15. This removes the limiting plate 11 from the outer wall of the insertion rod 10, allowing the guide trough 7 to be disassembled for easy cleaning. This prevents dry-mixed mortar from adhering to and accumulating on the inner wall of the guide trough 7, facilitating cleaning and ensuring the smooth flow of the mortar. The guide groove 7 guides the screened dry-mixed mortar. When installing the guide groove 7, the limiting plate 11 is placed on the outer wall of the insertion rod 10 and pushed towards the box 5. During this process, the guide groove 7 compresses the spring 13 through the moving plate 12. The limiting plate 11 presses the two rotating blocks 14 into the insertion rod 10. When the rotating blocks 14 pass through the limiting plate 11, the spring 15 returns to its original state and pushes the two rotating blocks 14 out of the insertion rod 10, thereby limiting the limiting plate 11 so that it cannot be removed from the insertion rod 10. The moving plate 12 is pushed towards the guide groove 7 through the spring 13, thereby ensuring the stability of the guide groove 7 and keeping the limiting plate 11 in contact with the rotating blocks 14, preventing the limiting plate 11 from moving on the outer wall of the insertion rod 10.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
