[0001] This utility model relates to the field of mortar preparation technology, and in particular to a vibrating screen for mortar preparation. Background Technology

[0002] In construction, mortar is an indispensable material used for bricklaying, plastering, and bonding tiles. The vibrating screen used for mortar preparation is mainly used to screen various raw materials and mixtures in the mortar production process, such as lime, fly ash, mineral powder, and fine sand, to ensure that the particle size of the materials meets the production requirements.

[0003] Currently, when vibrating screens are used to screen materials during mortar preparation, material may clog the screen, which reduces the screening efficiency and processing capacity of the vibrating screen. In some cases, manual shutdown may be required to clean the clogged screen, resulting in low working efficiency of the vibrating screen.

[0004] Furthermore, during the sieving of materials in mortar preparation, these materials may have clumped during previous storage. As a result, the clumped materials cannot be processed during the sieving process, leading to material waste, increased costs, and poor performance of the vibrating screen.

[0005] To address this issue, this utility model proposes a vibrating screen for mortar preparation. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a vibrating screen for mortar preparation, including a vibrating screen box and two fixed seats. The vibrating screen box is provided with two screens inside and several mounting plates inside.

[0009] An arc-shaped baffle is fixedly connected to one side of the movable block, and a support rod is fixedly connected to one side of the arc-shaped baffle. Several striking hammers are fixedly connected to the top of the support rod, and the striking hammers are located below the screen.

[0010] The bottom of one of the three support rods is fixedly connected to several fixed cylinders. A second spring is fixedly connected inside the fixed cylinder. A movable rod is provided inside the second spring. A limit plate is fixedly connected to the top of the movable rod.

[0011] Preferably, in any of the above embodiments, a square through hole is provided on one side of each of the six convex shells and the mounting plate, and a through hole is provided on the outside of the vibrating screen box.

[0012] The technical effect achieved by adopting the above solution is that when the vibrating screen is working, the connecting plate will slide inside the square through hole and the through hole of the vibrating screen box.

[0013] Preferably, in any of the above embodiments, a connecting plate is fixedly connected to one side of each of the six movable blocks, a limiting cylinder is fixedly connected to the top of the connecting plate, and a third spring is fixedly connected inside the limiting cylinder.

[0014] Preferably, in any of the above embodiments, a telescopic rod is fixedly connected to the top of the third spring, and the outside of the telescopic rod is slidably connected to the inside of the limiting cylinder.

[0015] Preferably, in any of the above embodiments, a fixing plate is fixedly connected to the top of the telescopic rod, a plurality of connecting rods are fixedly connected to the bottom of the fixing plate, and a second crushing plate is fixedly connected to the bottom of the connecting rods.

[0016] Preferably, the bottom of both the second crushing plate and the first crushing plate is provided with a plurality of cones.

[0022] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0023] 1. During the sieving of materials in mortar preparation, material may clog the screen, thereby reducing the screening efficiency and processing capacity of the vibrating screen, and even requiring the machine to be stopped to clean the blockage. By tapping the bottom of the screen with a hammer while the vibrating screen is working, the screen can be prevented from clogging. This solves the problem of having to manually stop the machine to clean the screen when it becomes clogged, and helps to improve the working efficiency of the vibrating screen.

[0024] 2. During the screening of materials in mortar preparation, these materials may have clumped during previous storage.

Detailed Implementation

[0036] Example 1: As Figures 1 to 8 As shown, a vibrating screen for mortar preparation includes a vibrating screen box 1 and two fixed seats 2. The vibrating screen box 1 is equipped with two screens 8, which are fixed to the vibrating screen box 1 by bolts. The two screens 8 perform secondary screening of the mortar preparation material. When using the vibrating screen, the material is conveyed to the inside of the vibrating screen box 1 and onto the screens 8. The vibrating motor 7 drives the entire vibrating screen box 1 to vibrate, so that the material is screened while vibrating on the screens 8. After the material is screened, the qualified material will enter the bottom of the vibrating screen box 1, and the remaining impurities will remain on the screens 8. They will be separated and collected by an external conveying device. The external conveying device is a known technology and will not be described in detail here. The vibrating screen box 1 is equipped with several mounting plates 9, which are also manually connected and fixed to the vibrating screen box 1 by bolts.

[0037] A convex shell 10 is fixedly connected to one side of the mounting plate 9. A slide rod 11 is fixedly connected inside the convex shell 10. A first spring 12 is provided on the outside of the slide rod 11. A movable block 13 is fixedly connected to the top of the first spring 12. The outside of the movable block 13 is slidably connected to the inside of the convex shell 10. When the material is screened on the screen 8, the vibrating screen box 1 vibrates as a whole, so the vibrating screen box 1 drives the hammer 16 to reciprocate. Affected by the vibrating screen box 1, the movable block 13 will move along the outside of the slide rod 11 inside the convex shell 10. At this time, the movable block 13 will stretch and compress the first spring 12 to realize the reciprocating movement of the movable block 13.

[0038] An arc-shaped baffle 14 is fixedly connected to one side of the movable block 13. It should be noted that the arc-shaped baffle 14 is set here to prevent the material from moving into the interior of the convex shell 10 when the screen 8 is screening the material. Over time, this will affect the normal operation of the movable block 13. Therefore, the arc-shaped baffle 14 can protect the interior of the convex shell 10 and prevent the material from entering the interior of the convex shell 10 during screening. A support rod 15 is fixedly connected to one side of the arc-shaped baffle 14. Several hammers 16 are fixedly connected to the top of the support rod 15. The hammers 16 are set below the screen 8. When the movable block 13 moves back and forth, it will drive the arc-shaped baffle 14 to move back and forth. At this time, the arc-shaped baffle 14 drives the support rod 15 and the hammers 16 to move back and forth. This is to realize that when the screen 8 is screening the material, the hammers 16 move back and forth and strike the bottom of the screen 8. The screen 8 is struck by the hammers 16. At this time, the screen 8 is subjected to the impact force, which can prevent the material from clogging the screen 8.

[0039] The bottom of each of the three support rods 15 is fixedly connected to several fixed cylinders 17. A second spring 18 is fixedly connected inside each fixed cylinder 17. A movable rod 19 is installed inside each second spring 18. A limit plate 20 is fixedly connected to the top of the movable rod 19. The bottom of the limit plate 20 is fixedly connected to the top of the second spring 18. The outside of the movable rod 19 is slidably connected to the inside of the fixed cylinder 17. A first crushing plate 21 is fixedly connected to the bottom of the movable rod 19. When the support rods 15 reciprocate, the movable block 13 also compresses the first spring 12. However, it should be noted that the compression of the first spring 12 by the movable block 13 is limited. Therefore, when the support rods 15 reciprocate, the second spring 18 is needed to coordinate with the first crushing plate 21 to achieve reciprocating movement. When the vibrating screen is working, it is affected by the vibrating box 1. The first crushing plate 21 will drive the movable rod 19 to reciprocate. The fixed cylinder 17 reciprocates inside. At this time, the limiting plate 20 of the movable rod 19 will compress the second spring 18, causing the first crushing plate 21 to descend and crush the agglomerated material on the screen 8. At the same time, due to the influence of the second spring 18, the limiting plate 20 and the movable rod 19 will be reset, so the first crushing plate 21 will rise to prevent the first crushing plate 21 from being too low and affecting the screening efficiency of the screen 8. It should be noted that because the force of the first crushing plate 21 is the vibration of the vibrating screen box 1 and the reciprocating movement of the second spring 18, the force of the first crushing plate 21 when it descends is limited. It can meet the requirements for crushing and separating agglomerated material, but this force is not enough to crush the impurities in the material. Therefore, the first crushing plate 21 will not crush the impurities, which will cause the crushed impurities to enter the qualified material after screening.

[0040] The six convex shells 10 and the mounting plate 9 each have a square through hole on one side. The vibrating screen box 1 has a through hole on the outside. When the vibrating screen is working, the connecting plate 22 will slide inside the square through hole and the through hole of the vibrating screen box 1.

[0041] One side of each of the six movable blocks 13 is fixedly connected to a connecting plate 22, the top of the connecting plate 22 is fixedly connected to a limiting cylinder 23, and the inside of the limiting cylinder 23 is fixedly connected to a third spring 24.

[0042] The top of the third spring 24 is fixedly connected to a telescopic rod 25, and the outside of the telescopic rod 25 is slidably connected to the inside of the limiting cylinder 23.

[0043] A fixed plate 26 is fixedly connected to the top of the telescopic rod 25, and several connecting rods 27 are fixedly connected to the bottom of the fixed plate 26. A second crushing plate 28 is fixedly connected to the bottom of the connecting rods 27. When the vibrating screen box 1 vibrates, it will drive the second crushing plate 28 to reciprocate. At this time, the telescopic rod 25 will reciprocate inside the limiting cylinder 23. The bottom of the telescopic rod 25 will squeeze the third spring 24. At the same time, the third spring 24 will lift the telescopic rod 25 to reset it, preventing the second crushing plate 28 from being too low and affecting the screening efficiency of the material on the screen 8. When the telescopic rod 25 reciprocates, it will drive the fixed plate 26 to reciprocate, which will cause the fixed plate 26 to drive the connecting rods 27 and the second crushing plate 28 to reciprocate. This is to achieve the crushing of the agglomerated material on the screen 8 by the second crushing plate 28. The second crushing plate 28 is the same as the first crushing plate 21, and the points to note are also the same.

[0044] The bottom of both the second crushing plate 28 and the first crushing plate 21 is provided with several cones. The cones at the bottom of the first crushing plate 21 and the second crushing plate 28 are used to crush the clumps of material on the screen 8. Note that the plates cannot be used directly to crush the clumps of material, as this may cause the material to be flattened rather than crushed.

[0045] Several support seats 3 are fixedly connected to the bottom of each of the two fixed seats 2, and a fixed block 4 is fixedly connected to the top of the fixed seat 2. Both the fixed seat 2 and the fixed block 4 are equipped with shock-absorbing springs 5. The shock-absorbing springs 5 ​​are a double spring system, which can provide a larger buffer space and buffer force. When the vibrating screen box 1 vibrates, it can effectively absorb and alleviate the impact force generated by the vibration, and reduce the impact of the vibrating screen box 1 on the foundation support structure.

[0046] A connecting elbow 6 is fixedly connected to the top of the shock-absorbing spring 5, and one end of the connecting elbow 6 is fixedly connected to one side of the vibrating screen box 1 by bolts.

[0047] A vibration motor 7 is installed at the bottom of the vibrating screen box 1. The vibration motor 7 works to transmit the excitation force to the vibrating screen box 1, thereby causing the entire vibrating screen box 1 to vibrate.

[0048] A vibrating screen for mortar preparation operates on the following principle:

[0049] First, when using the vibrating screen, the material is conveyed to the inside of the vibrating screen box 1 and onto the screen 8. The vibrating motor 7 drives the entire vibrating screen box 1 to vibrate, so that the material vibrates on the screen 8 while being screened. When the material is screened on the screen 8, because the entire vibrating screen box 1 vibrates, the vibrating screen box 1 drives the hammer 16 to reciprocate. Affected by the vibrating screen box 1, the movable block 13 moves along the outside of the slide rod 11 inside the convex shell 10. At this time, the movable block 13 stretches and compresses the first spring 12 to achieve the reciprocating movement of the movable block 13. When the movable block 13 reciprocates, it drives the arc baffle 14 to reciprocate. At this time, the arc baffle 14 drives the support rod 15 and the hammer 16 to reciprocate. This allows the hammer 16 to reciprocate and strike the bottom of the screen 8 when the screen 8 is screening the material. The screen 8 is struck by the hammer 16. At this time, the impact force on the screen 8 can prevent the material from clogging the screen 8.

[0050] Secondly, when the support rod 15 moves back and forth, the movable block 13 will also compress the first spring 12. However, it should be noted that the compression of the first spring 12 by the movable block 13 is limited. Therefore, when the support rod 15 moves back and forth, it is also necessary to cooperate with the second spring 18 to realize the reciprocating movement of the first crushing plate 21. When the vibrating screen is working, it is affected by the vibrating box 1. The first crushing plate 21 will drive the movable rod 19 to move back and forth inside the fixed cylinder 17. At this time, the limiting plate 20 of the movable rod 19 will compress the second spring 18, so that the first crushing plate 21 will descend to crush the material clumps on the screen 8. At the same time, due to the influence of the second spring 18, the limiting plate 20 and the movable rod 19 will be reset. Therefore, the first crushing plate 21 will rise to prevent the first crushing plate 21 from being too low and affecting the screening efficiency of the screen 8.

[0051] Finally, when the vibrating screen box 1 vibrates, it will drive the second crushing plate 28 to reciprocate. At this time, the telescopic rod 25 will reciprocate inside the limiting cylinder 23. The bottom of the telescopic rod 25 will squeeze the third spring 24. At the same time, the third spring 24 will lift the telescopic rod 25 to reset it, preventing the second crushing plate 28 from being too low and affecting the screening efficiency of the material on the screen 8. When the telescopic rod 25 reciprocates, it will drive the fixed plate 26 to reciprocate, which will in turn drive the connecting rod 27 and the second crushing plate 28 to reciprocate. This will enable the second crushing plate 28 to crush the lumpy material on the screen 8. After the material screening is completed, the qualified material will enter the bottom of the vibrating screen box 1, and the remaining debris will remain on the screen 8 and be collected by the external conveying device.

[0052] 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.
