Description

Technical Field

[0001] The utility model relates to the technical field of mortar storage barrels, in particular to a screening component and a mortar storage barrel. Background Art

[0002] In construction projects, a large amount of cement mortar is usually required. Cement mortar is a mortar made of cement, fine aggregate and water according to needs. After the mixing is completed, it needs to be stored in a storage bucket for the convenience of subsequent use.

[0003] When the screening assembly of the existing mortar storage barrel is in use, a screen is used to screen impurities in the mortar. However, the mesh size of the screen is usually fixed. Therefore, when the size of the screen mesh is to be adjusted, the screen can only be removed from the screening assembly and then replaced with a screen of a different mesh size, which makes the operation process very cumbersome and cannot meet the user's needs. Utility Model Content

[0004] The purpose of the present invention is to provide a screening assembly and a mortar storage bucket to solve the problem in the background art that the screening assembly of the currently used mortar storage bucket is inconvenient to adjust the size of the mesh.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a screening assembly, comprising: a mounting frame and a first screen, a driving motor being installed inside the mounting frame through a groove, an output end of the driving motor being connected to a driving shaft through a coupling, a cam being sleeved on the outer side of the driving shaft, a first connecting block being provided on both sides of the cam, a fixed rod being installed on one side of the first connecting block, a movable frame being installed on one side of the fixed rod, a movable frame being installed on one side of the movable frame, and the first screen being installed inside the movable frame;

[0006] A gear ring is installed on the top of the movable frame through a groove, a connecting frame is installed on the top of the gear ring, a second screen is installed in the middle of the connecting frame, and a block that passes through the movable frame is provided on one side of the gear ring.

[0007] Preferably, a movable spring is connected between the clamping block and the groove of the movable frame, and a fixed block is installed on the top of the movable frame.

[0008] Preferably, a first telescopic block is installed through the top of the fixed block, and a return spring is installed between the first telescopic block and the fixed block.

[0009] Preferably, second connecting blocks are installed around the first screen and the second screen, and a movable block is connected through the middle of the second connecting block.

[0010] Preferably, a second telescopic block is installed on one side of the movable block.

[0011] Preferably, a telescopic spring is installed between the second telescopic block and the groove of the second connecting block, and a protrusion is installed on the side of the movable block away from the second telescopic block.

[0012] Preferably, a barrel body is installed on the outer side of the mounting frame, and a barrel cover is installed on the top of the barrel body.

[0013] Compared with the prior art, the beneficial effect of the present invention is that when the screening assembly and the mortar storage bucket are in use, the card block can be pulled in the direction away from the gear ring according to the use requirements, so that the card block is separated from the gear ring. When the card block moves, the first telescopic block in the fixed block will be squeezed upward through the inclined surface, so that the reset spring is in a stretched state. When the through hole on the top of the card block is aligned with the first telescopic block, the first telescopic block will be reset by the reset spring, so that the position of the card block can be fixed. Without the card block limiting the gear ring, the gear ring and the connecting frame can drive the second screen to rotate, and then the first screen and the second screen will be misaligned, so that finer impurities can be filtered. This is the use feature of the screening assembly and the mortar storage bucket.

[0014] 1. When it is necessary to filter finer impurities in the mortar, the screening assembly and mortar storage bucket can pull the block to one side to separate the block from the gear ring. At the same time, the block will be limited to one side of the fixed block through the resetting action of the first telescopic block. At this time, the connecting frame can be rotated to drive the second screen to rotate, thereby causing the first screen and the second screen to be misaligned, which is convenient for filtering finer impurities.

[0015] 2. When the first screen and the second screen need to be replaced and cleaned, the screening assembly and the mortar storage bucket only need to pull the movable block in the corresponding second connecting block to one side so that the protrusion on one side of the movable block is not connected to the movable frame or the connecting frame. At this time, the first screen and the second screen can be removed from the movable frame and the connecting frame respectively, thereby facilitating the replacement and cleaning of the first screen and the second screen.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 The utility model provides a technical solution: a screening assembly, comprising: a mounting frame 1 and a first screen 7, a driving motor 2 is installed inside the mounting frame 1 through a groove, the output end of the driving motor 2 is connected to a driving shaft 3 through a coupling, a cam 4 is sleeved on the outer side of the driving shaft 3, a first connecting block 5 is provided on both sides of the cam 4, a fixed rod is installed on one side of the first connecting block 5, a movable frame 6 is installed on one side of the fixed rod, and the first screen 7 is installed inside the movable frame 6;

[0023] A gear ring 8 is installed on the top of the movable frame 6 through a groove, a connecting frame 9 is installed on the top of the gear ring 8, a second screen 10 is installed in the middle of the connecting frame 9, a clamping block 11 is provided on one side of the gear ring 8 and passes through the movable frame 6, a movable spring 12 is connected between the clamping block 11 and the groove of the movable frame 6, a fixed block 13 is installed on the top of the movable frame 6, a first telescopic block 14 is installed on the top of the fixed block 13, a return spring 15 is installed between the first telescopic block 14 and the fixed block 13, and one end of the clamping block 11 and the end close to the first telescopic block 14 are both inclined structures.

[0024] During specific implementation, when the screening assembly and the mortar storage bucket need to filter finer impurities, the block 11 can be pulled to the side away from the gear ring 8, so that the gear ring 8 is separated from the block 11. At the same time, the movement of the block 11 will compress the movable spring 12 in the groove of the movable frame 6, and the block 11 will pass through the groove of the fixed block 13. Since one end of the block 11 and the end close to the first telescopic block 14 are both inclined structures, when the block 11 moves toward the inside of the fixed block 13, it will squeeze the first telescopic block 14 through the inclined surface, so that the first telescopic block 14 moves upward, and the reset spring 12 will return to the original position. 15 will be in a stretched state. When the first telescopic block 14 is aligned with the through hole in the middle of the card block 11, the reset spring 15 will drive the first telescopic block 14 to reset, so that the first telescopic block 14 is inserted into the groove of the card block 11. The card block 11 can be limited and fixed by the first telescopic block 14. Without the card block 11 docking with the toothed ring 8 at the bottom of the connecting frame 9, the toothed ring 8 can be rotated along the movable frame 6, thereby driving the top connecting frame 9 and the second screen 10 to rotate. The rotation of the second screen 10 will cause the mesh between the first screen 7 to be misaligned, and at this time, finer impurities can be filtered;

[0025] On the contrary, the first telescopic block 14 can be pulled toward the top of the fixed block 13 so that the first telescopic block 14 does not limit the block 11. Then, the reset action of the movable spring 12 will cause the block 11 to move in the opposite direction, thereby docking the block 11 with the gear ring 8. Through the cooperation between the block 11 and the gear ring 8, the connecting frame 9 and the second screen 10 can be prevented from rotating, thereby ensuring the stability of the second screen 10.

[0026] See Figure 1 、 Figure 3 and Figure 4 It can be seen that when in use, the block 11 can be pulled away from the gear ring 8 according to the use requirements, so that the block 11 is separated from the gear ring 8. Without the docking effect between the block 11 and the gear ring 8, the gear ring 8 can drive the second screen 10 to rotate through the connecting frame 9, thereby causing the first screen 7 and the second screen 10 to be misaligned, and at this time, finer impurities can be filtered.

[0027] Second connecting blocks 16 are installed around the first screen 7 and the second screen 10, and a movable block 17 is connected through the middle of the second connecting block 16. A second telescopic block 18 is installed on one side of the movable block 17. A telescopic spring 19 is installed between the second telescopic block 18 and the groove of the second connecting block 16. A protrusion 20 is installed on the side of the movable block 17 away from the second telescopic block 18. The second telescopic block 18 forms a telescopic structure with the second connecting block 16 through the telescopic spring 19.

[0028] During specific implementation, when the first screen 7 needs to be replaced and cleaned, the movable block 17 on one side of the second connecting block 16 can be pulled to one side, so that the movable block 17 squeezes the telescopic spring 19 through the second telescopic block 18. At the same time, the movement of the movable block 17 to one side will cause the protrusion 20 on one side to move out of the groove of the movable frame 6. Without the protrusion 20 docking with the groove of the movable frame 6, the first screen 7 can be removed from the movable frame 6, thereby facilitating the replacement and cleaning of the first screen 7. Similarly, the above steps can be repeated to remove the second screen 10 from the connecting frame 9 for cleaning and replacement;

[0029] On the contrary, the second connecting blocks 16 around the first screen 7 can be docked into the grooves at the top of the movable frame 6, and then the movable block 17 can be released. The movable block 17 will be reset through the second telescopic block 18 and the telescopic spring 19, so that the movable block 17 drives the protrusion 20 on one side to dock into the grooves of the movable frame 6. The first screen 7 can be installed in the middle of the movable frame 6 through the protrusion 20 on one side of the movable block 17. Similarly, the second screen 10 can be installed in the middle of the connecting frame 9, so that the first screen 7 and the second screen 10 can be installed and fixed quickly and conveniently.

[0030] See Figure 1 、 Figure 3 and Figure 4 It can be seen that during use, the first screen 7 and the second screen 10 can be quickly removed from the corresponding movable frame 6 and the connecting frame 9 according to the use requirements of the first screen 7 and the second screen 10, so as to facilitate the replacement and cleaning of the first screen 7 and the second screen 10.

[0031] A barrel body 21 is installed on the outer side of the mounting frame 1 , and a barrel cover 22 is installed on the top of the barrel body 21 , and the barrel body 21 and the barrel cover 22 are tightly fitted together.

[0032] In specific implementation, when the screening assembly and the mortar storage bucket are in use, the bucket cover 22 can be removed from the top of the barrel body 21, and then the mortar can be poured into the interior of the barrel body 21, and finally the bucket cover 22 can be installed on the barrel body 21 by snapping.

[0033] See Figure 1 and Figure 2 It can be seen that the mortar can be poured into the interior of the barrel body 21 according to needs, and then the barrel cover 22 is fixed on the barrel body 21, so as to facilitate the storage of the mortar.

[0034] To sum up: when the screening component and the mortar storage bucket are in use, the barrel body 21 can be placed in a stable position, and then the mortar to be stored is poured into the interior of the barrel body 21. During the process of pouring the mortar, the drive motor 2 is started, so that the drive motor 2 drives the cam 4 to rotate through the drive shaft 3. A first connecting block 5 is provided on both sides of the cam 4. Therefore, when the cam 4 rotates, it will drive the movable frame 6 to reciprocate through the first connecting block 5 and the fixed rod, so that the first screen 7 can vibrate left and right, and the mortar can be screened at this time. This is the use feature of the screening component and the mortar storage bucket. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
