[0003] In existing concrete building material additive weighing devices, the filtration mechanism filters the additives, but impurities remain above the filter screen, making them difficult to remove. Furthermore, the filter screen is fixedly connected to the connecting rod and cannot be disassembled, hindering cleaning. Therefore, we propose a concrete building material additive weighing device to address these problems. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0045] Figures 1-19 As shown, this application provides a concrete building material additive weighing device, which can filter and weigh concrete building material additives.

[0046] The concrete building material additive weighing device includes a filter box, which contains a filter assembly, a vibration assembly, an elastic assembly, and an installation assembly. The vibration assembly drives the filter assembly to move up and down, thereby filtering the concrete building material additive added to the filter box. The elastic assembly provides cushioning and support for the up-and-down movement of the filter assembly, ensuring stable and effective periodic movement. The installation assembly allows for the installation and removal of the filter assembly within the filter box, facilitating quick and easy replacement and cleaning of impurities.

[0047] The filter box includes a box body 101, which is a hollow structure. The box body 101 can be rectangular, cylindrical, or other shapes and structures, without any specific restrictions.

[0048] The filter box includes a filter base 102, which is disposed inside the box body 101 and located at the bottom of the box body 101. The filter base 102 has a funnel-shaped channel running vertically through it to facilitate the passage of concrete building material additives.

[0049] In one embodiment of this application, the housing 101 is rectangular parallelepiped, and the filter base 102 is rectangular parallelepiped. The filter base 102 can be fixedly disposed inside the housing 101, or the filter base 102 and the housing 101 can be integrally formed, or the filter base 102 can be disposed inside the housing 101 in other ways, without specific limitations.

[0050] The top inlet of the housing 101 is connected to a feeding hopper 103. Concrete building material additives enter the housing 101 through the feeding hopper 103 and the top inlet of the housing 101. The feeding hopper 103 is provided with a funnel-shaped channel that runs vertically through the housing to facilitate the passage of concrete building material additives.

[0051] The bottom outlet of the housing 101 is equipped with a connected metering element 104 and a discharge pipe 105. Concrete building material additives, after being filtered by the filter assembly, enter the metering element 104. The metering element 104 is equipped with a control valve (not shown in the figure). The flow of additives within the metering element 104 can be controlled by opening and closing the control valve. When weighing the additives is required, the control valve can be closed. After the additives are weighed by the metering element 104, the control valve is opened, allowing the additives to be discharged from the filter housing through the discharge pipe 105.

[0052] The measuring element 104 can be rectangular, and has a funnel-shaped channel running vertically through it to facilitate the passage of concrete building material additives. The method by which the measuring element 104 measures and weighs the concrete building material additives can be a method commonly used in this technical field, and no specific limitation is made here.

[0053] The number of filter components can be multiple, and multiple filter components are arranged in parallel inside the housing 101, with the filter components corresponding to the inlet of the housing 101; concrete building material additives can be filtered by falling directly onto the filter components through the feeding hopper to remove impurities from the concrete building material additives.

[0054] In one embodiment of this application, there are two filter components, which are arranged in parallel and spaced apart, so as to perform two-stage filtration of concrete building material additives.

[0055] The filter assembly includes a fixed frame 201, within which a filter plate 202 is detachably connected. The filter plate 202 is used to filter additives. The filter plate 202 can be any filter plate with a filtering function commonly used in this technical field, and no specific limitation is made herein.

[0056] In one embodiment of this application, the fixing frame 201 is a single piece, a cuboid frame structure, and hollow inside. The fixing frame 201 includes two parallel first frame edges 2011 and two parallel second frame edges 2012. The two parallel first frame edges 2011 have corresponding frame grooves 2013, which are arranged along the length of the first frame edges 2011. The two parallel second frame edges 2012 have frame openings 2014, which are arranged along the length of the second frame edges 2012. The filter plate 202 can be rectangular in shape. The filter plate 202 is inserted through one of the frame openings 2014, and both sides of the filter plate 202 slide into the fixing frame 201 along the two frame grooves 2013 until the filter plate 202 is completely inserted into the fixing frame 201, thereby enabling a detachable connection of the filter plate 202 within the fixing frame 201.

[0057] The two sides of the filter plate 202 are in contact with the inner sides of the two frame grooves 2013, which can limit the filter plate 202 and prevent the filter plate 202 from shifting and shaking along the direction of the second frame 2012.

[0058] In actual use, the filter plate 202 often becomes damaged and clogged. This application can facilitate the quick and easy disassembly and replacement of the filter plate 202, so as to make timely maintenance and cleaning of the filter plate 202 and ensure that the filter plate 202 can play an effective filtering role.

[0059] When it is necessary to disassemble the filter plate 202, simply slide the filter plate 202 out of the fixing frame 201. This allows for convenient and quick connection and disassembly of the filter plate 202, and facilitates the cleaning of impurities on the filter plate 202.

[0060] Both first frame frames 2011 have protruding protective plates 203 fixed on their surfaces. The protective plates 203 can block and limit the concrete building material additives on the filter plate 202, preventing the concrete building material additives from overflowing from both sides of the filter plate 202.

[0061] The mounting assembly includes a mounting base 501 and a mounting post 502, which are located on opposite sides of the mounting frame 201. Specifically, the mounting base 501 and the mounting post 502 are located on the outer sides of the two first frame sides 2011. The mounting base 501 and the mounting post 502 have corresponding clearance grooves 503 on their respective sides. The outer sides of the two first frame sides 2011 are each fixed with a protruding plate 204, which engages with the two clearance grooves 503.

[0062] The outer side of the two first frame 2011 refers to the side of the two first frame 2011 facing away from each other. The thickness of the convex plate 204 is equal to the thickness of the first frame 2011. The top surface of the convex plate 204 is flush with the top surface of the first frame 2011, and the bottom surface of the convex plate 204 is flush with the bottom surface of the first frame 2011.

[0063] The fixed frame 201, the protective plate 203 and the convex plate 204 can be integrally formed by processing technology or fixed into a single piece by other means, without specific restrictions.

[0064] like Figure 18As shown, the distance between the two first frame edges 2011 is equal to the distance between the inner sides of the fixing seat 501 and the fixing post 501, allowing the outer sides of the two first frame edges 2011 to fit and abut against the inner sides of the fixing seat 501 and the fixing post 501, respectively, thereby limiting the filter assembly in the lateral direction. Therefore, when the fixing seat 501, the filter assembly, and the fixing post 502 are combined, the filter assembly cannot move in the lateral direction. The fixing seat 501 and the fixing post 502 can limit the filter assembly in the lateral direction, preventing the filter assembly from tilting and vibrating in the lateral direction, thereby preventing additive leakage and spillage.

[0065] like Figure 19 As shown, the convex plate 204 is U-shaped, and its protruding edge is fixed to the outer side of the first frame 2011. The corresponding gap groove 503 is adapted to the shape and structure of the convex plate 204. The convex plate 204 fits in the gap groove 503, which can limit the convex plate 204 and effectively prevent it from dislodging from the gap groove 503. Through the cooperation of the convex plate 204 and the gap groove 503, the filter assembly, the fixing seat 501, and the fixing post 502 can be assembled together.

[0066] like Figure 19 As shown, the width 'a' of the protruding plate 204 is equal to the width of the gap groove 503, and the length 'b' of the protruding plate 204 is equal to the length of the gap groove 503. This allows the outer surface and two outer end faces of the protruding plate 204 to fit snugly against the inner surface and two inner end faces of the gap groove 503, respectively. This ensures that the protruding plate 204 can be stably and effectively fitted within the gap groove 503, effectively preventing it from detaching from the groove. Therefore, when the fixing base 501, the filter assembly, and the fixing column 502 are combined, the filter assembly cannot move laterally. The fixing base 501 and the fixing column 502 can limit the lateral movement of the filter assembly, preventing it from tilting or vibrating laterally, thus preventing additive leakage.

[0067] like Figure 12 , Figure 13 and Figure 14 As shown, the height T of the convex plate 204 is less than the height H of the gap groove 503, providing clearance for the convex plate 204 to move up and down. The convex plate 204 moves up and down within the gap groove 503, which limits its movement, preventing the filter assembly from shifting or falling off. Simultaneously, the close contact between the convex plate 204 and the gap groove 503 prevents the filter assembly from moving laterally, thus vertically limiting its movement and ensuring effective vertical movement, preventing it from shifting or tilting.

[0068] The inner surface of the gap groove 503 can be coated with a layer of lubricating grease (not shown in the figure), which can reduce the friction between the protrusion 204 and the gap groove 503, so that the filter assembly can move up and down smoothly and effectively.

[0069] In one embodiment of this application, the protective plate 203 is a single piece. The protective plate 203 includes a first protective plate 2031 vertically fixed to the surface of the first frame 2011, second protective plates 2032 vertically fixed to both ends of the first protective plate 2031, the second protective plates 2032 vertically fixed to the surface of the first frame 2011, and a third protective plate 2033 vertically fixed to the top of the protective plate 2031. The third protective plate 2033 is parallel to the surface of the first frame 2011. The first protective plate 2031 and the third protective plate 2033 are both arranged along the length direction of the first frame 2011. The first protective plate 2031, the second protective plate 2032, and the third protective plate 2033 form a groove structure with an opening facing the gap groove 503.

[0070] like Figure 12 , Figure 13 and Figure 14 As shown, in one embodiment of this application, the height E of the first protective plate 2031 is equal to or greater than the difference between the height H of the gap groove 503 and the height T of the protruding plate 204. When the filter assembly does not move up or down, the third protective plate 2033 and the two second protective plates 2032 can fit against the inner side of the fixing seat 501 and / or the inner side of the fixing column 502, thereby sealing the gap groove 503 and preventing concrete building material additives from entering the gap groove 503. In addition, through the contact between the third protective plate 2033 and the two second protective plates 2032 and the inner side of the fixing seat 501 and / or the inner side of the fixing column 502, the filter assembly can also be limited in the lateral direction, making it impossible for the filter assembly to move in the lateral direction.

[0071] In one embodiment of this application, the inner side of the fixing seat 501 and the inner side of the fixing post 502 refer to the corresponding sides of the fixing seat 501 and the fixing post 502.

[0072] In one embodiment of this application, since there are two filter components, the corresponding fixing base 501 is provided with two vertically parallel gap grooves 503, and there are two fixing posts 502. The two fixing posts 502 are arranged vertically parallel and spaced apart, and both fixing posts 502 are provided with gap grooves 503. The two fixing posts 502 are located on the same side of the two filter components, and the gap grooves 503 of the two fixing posts 502 are respectively in clearance fit with the protrusions 204 of the two filter components. The fixing base 501 is located on the other side of the two filter components, and the two gap grooves 503 on the fixing base 501 are respectively in clearance fit with the protrusions 204 of the two filter components.

[0073] The mounting assembly also includes a hollow column 504 fixed to the outer wall of the housing 101. The hollow column 504 is cuboid in shape and is vertically fixed to the outer wall of the housing 101. A partition 512 is provided inside the hollow column 504, which divides the interior of the hollow column 504 into an upper inner cavity with an upward opening and a lower inner cavity with a downward opening. Both the upper and lower inner cavities are provided with limiting springs 506. One end of the limiting spring 506 is in contact with the partition 512, and the other end is fixed with a push plate 505. A limiting block 507 is fixed on the push plate 505. The push plate 505 and the limiting block 507 can slide up and down in the inner cavity of the hollow column 504.

[0074] A rod 508 is fixed to the outside of the fixed column 502, and a limiting groove 509 is provided in the rod 508. When the limiting block 507 slides into the limiting groove 509, the fixed column 502 is locked and limited, so that the fixed column 502, the filter assembly and the fixed seat 501 are locked and limited in the filter box in the lateral direction.

[0075] The insertion rod 508 protrudes and is fixed to the outside of the fixing post 502. The insertion rod 508 can be integrally formed with the fixing post 502, or fixed together in other ways. No specific restrictions are made here.

[0076] like Figure 11 , Figure 12 , Figure 13 and Figure 15 As shown in one embodiment of this application, the side of the limiting block 507 facing the fixed post 502 is an inclined surface 5071. The angle between the inclined surface 5071 and the vertical direction is an acute angle, and the angle between the inclined surface 5071 and the horizontal direction is also an acute angle. By setting the inclined surface 5071, the limiting block 507 can easily enter and exit the limiting groove 509, and the locking and unlocking of the fixed post 502 can be achieved conveniently and quickly. In addition, it can ensure that when the limiting block 507 is engaged in the limiting groove 509, it plays a stable and effective locking and limiting role for the fixed post 502.

[0077] The limiting groove 509 is vertically inserted into the insertion rod 508. The shape and structure of the limiting groove 509 are adapted to the shape and structure of the limiting block 507. The limiting groove 509 is provided with an inclined groove surface (not shown in the figure) that is parallel to the inclined surface 5071. When the limiting block 507 is fitted into the limiting groove 509, the inclined surface 5071 and the inclined groove surface are in contact.

[0078] like Figure 11 and Figure 15As shown, in one embodiment of this application, the outer side of the push plate 505 is provided with a drive slider 510, and the hollow column 504 is provided with a through hole 511. The through hole 511 is rectangular and vertically arranged. The drive slider 510 extends out of the through hole 511 and can slide up and down in the through hole 511. The drive slider 510 can slide up and down along the through hole 511. The up and down sliding of the drive slider 510 can conveniently and quickly drive the push plate 505 and the limiting block 507 to slide up and down.

[0079] The limiting spring 506 can reset the limiting block 507, so that the upper and / or lower limit block 507 can be automatically reset, thereby making it easy and quick to lock and unlock the fixing column 502, and thus making it easy and quick to install and disassemble the filter assembly.

[0080] One end of the limiting spring 506 can be fixedly connected to the partition plate 512, and the other end of the limiting spring 506 can be fixedly connected to the push plate 505, which can realize the effective compression and / or rebound reset of the limiting spring 506. No specific restrictions are made here.

[0081] The push plate 505, the limit block 507 and the drive slider 510 can be fixed as a single unit, and no specific restrictions are imposed here.

[0082] Multiple insertion rods 508 are evenly spaced on the outer surface of the fixed post 502, and there are also multiple hollow posts 504. Each hollow post 504 simultaneously cooperates with two fixed posts 502, one above and one below. Specifically, the limiting block 507 at the top of the hollow post 504 cooperates with the insertion rod 508 of the upper fixed post 502, and the limiting block 507 at the bottom of the hollow post 504 cooperates with the insertion rod 508 of the lower fixed post 502. Through the cooperation of multiple insertion rods 508 and hollow posts 504, the fixed post 502 can be stably and effectively locked and unlocked.

[0083] The box body 101 has an opening 106 corresponding to the fixed seat 501 and an opening 107 corresponding to the plug rod 508 on its box wall. The opening 106 and the opening 107 are respectively set on two corresponding box walls of the box body 101.

[0084] The opening 106 can be rectangular to fit the fixing base 501, with the fixing base 501 fitting within the opening 106 with a clearance. The four right angles of the opening 106 are rounded to facilitate the entry and exit of the fixing base 501.

[0085] The number of openings 107 is equal to the number of inserts 508. The inserts 508 can extend out of the openings 106 so that the limiting grooves 509 on the inserts 508 can cooperate with the limiting blocks 507.

[0086] The installation component of this application allows for the installation and removal of the filter assembly, specifically:

[0087] The process of disassembling the filter assembly includes: pushing the drive slider 510 to slide, with the upper drive slider 510 sliding downwards and the lower drive slider 510 sliding upwards, thereby causing the upper limiting block 507 to move downwards and disengage from the limiting groove 509 of the upper fixing post 502, and the lower limiting block 507 to move upwards and disengage from the limiting groove 509 of the lower fixing post 502, thus releasing the lock on the upper and lower fixing posts 502, and thus unlocking the fixing posts 502, the filter assembly, and the fixing seat 501 as a whole. Pulling the fixing seat 501 outwards causes the fixing seat 501 to detach from the housing 101. As the fixing seat 501 moves outwards, it simultaneously drives the two fixing posts 502 and the two filter assemblies outwards, so that the two fixing posts 502, the two filter assemblies, and the fixing seat 501 simultaneously move out of the housing 101 through the opening 106, thus achieving the disassembly of the filter assembly.

[0088] The installation process of the filter assembly includes: placing the fixing base 501 and two fixing posts 502 on both sides of the two filter assemblies respectively; inserting the protruding plates 204 on both sides of the filter assembly into the gap grooves 503 of the fixing base 501 and the gap grooves 503 of the fixing posts 502 respectively; and assembling the two fixing posts 502, the two filter assemblies, and the fixing base 501 together laterally. Inserting the assembled fixing posts 502, filter assemblies, and fixing base 501 into the housing 101 through the opening 106 until the insertion rod 508 on the fixing post 502 protrudes from the opening 107, the filter assembly extends into the housing 101, and the fixing base 501 engages within the opening 106.

[0089] As the fixed post 502 extends into the housing 101, the drive slider 510 is pushed to slide towards the other side, causing the two limit springs 506 to be in a compressed state and the two limit plates 507 to retract into the inner cavity of the hollow post 504 to prevent the limit plates 507 from obstructing the insertion rod 508 from extending out of the opening 107. After the insertion rod 508 extends out of the opening 107, the two drive sliders 510 are released, and the two limit springs 506 extend and reset. At the same time, the upper drive slider 510 can slide upward and the lower drive slider 510 can slide downward, so that the upper limit block 507 can move upward and extend into the limit groove 509 of the upper fixed post 502, and the lower limit block 507 can move downward and extend into the limit groove 509 of the lower fixed post 502. This locks the upper and lower fixed posts 502, allowing the two fixed posts 502, two filter components, and the fixed base 501 to be installed on the housing 101.

[0090] A handle 513 is fixed to the outside of the mounting base 501. By holding the handle 513, the mounting base 501 can be moved easily, thereby facilitating the installation and removal of the filter assembly.

[0091] The vibration component is positioned between two adjacent filter components and is used to drive the filter components to move up and down.

[0092] The vibration assembly includes two parallel rotating shafts 301, which are rotatably disposed between two filter plates 202.

[0093] Both ends of the two rotating shafts 301 extend out of the housing 101, and one end of each rotating shaft 301 is connected to a gear 302. A meshing wheel 303 meshes between the two gears 302, and both gears 302 and the meshing wheel 303 are located on the outside of the housing 101. The rotation directions of the two gears 302 and the meshing wheel 303 are opposite, thus allowing the two rotating shafts 301 to rotate in the same direction. For example, the rotation directions of the two gears 302 may be counterclockwise and the rotation directions of the meshing wheel 303 may be clockwise; or, the rotation directions of the two gears 302 may be clockwise and the rotation directions of the meshing wheel 303 may be counterclockwise. No specific limitation is made here.

[0094] One of the rotating shafts 301 has a motor 304 connected to its extended end. The motor 304 is located outside the housing 101. The motor 304 can drive the rotating shaft 301 to rotate. Through the connection of two gears 302 and meshing wheel 303, it can drive the other rotating shaft 301 to rotate synchronously, and the two rotating shafts 301 rotate in the same direction.

[0095] A cam 305 is fixed on the rotating shaft 301. The rotation of the rotating shaft 301 can drive the rotating cam 302 to rotate, and the rotation of the cam 305 can drive the filter assembly to move up and down.

[0096] The rotating shaft 301 and the cam 305 can be integrally formed, or connected as one piece by a fixing method commonly used in the art, without any specific limitation.

[0097] Cam 305 is a single piece, including a first cam 3051 and a second cam 3052. The diameter of the first cam 3051 is larger than the diameter of the second cam 3052. Rotation shaft 301 passes through and connects to the center of the first cam 3051.

[0098] The second cams 3052 on the two rotating shafts 301 face opposite directions, and the cams 305 on the two rotating shafts 301 can rotate synchronously with the rotating shafts 301 in the same direction. Figure 12As shown, assuming the rotation direction of the rotating shaft 301 is always clockwise, the rotation direction of the cam 305 is also always clockwise. A full 360° clockwise rotation causes the left cam 305 to rotate 90° clockwise, driving the upper filter assembly upwards; simultaneously, the right cam 305 rotates 90° clockwise, driving the lower filter assembly downwards. When the left cam 305 rotates clockwise from 90° to 180°, the upper filter assembly moves downwards to its reset position; simultaneously, when the right cam 305 rotates clockwise from 90° to 180°, the lower filter assembly moves upwards to its reset position. When the left cam 305 rotates clockwise from 180° to 270°, it drives the lower filter assembly downwards; simultaneously, when the right cam 305 rotates clockwise from 180° to 270°, it drives the upper filter assembly upwards. When the left cam 305 rotates clockwise from 270° to 360°, the lower filter component moves upward and resets; simultaneously, when the right cam 305 rotates clockwise from 270° to 360°, the upper filter component moves downward and resets. In summary, a 360° rotation of the two cams 305 enables the vertical movement of the two filter components, and the vertical movement of the two filter components is synchronized.

[0099] In other preferred embodiments, the second cams 3052 on the two rotating shafts 301 are oriented in the same direction, and the cams 305 on the two rotating shafts 301 can rotate synchronously with the rotating shafts 301 in the same direction. Assuming that the second cams 3052 are both oriented towards the fixed seat 501, and the rotation direction of the rotating shafts 301 is clockwise, then the rotation direction of the cams 305 is also clockwise. A 360° clockwise rotation results in the two cams 305 rotating 90° clockwise, which drives the lower filter assembly to move downwards; when the two cams 305 rotate clockwise from 90° to 180°, the lower filter assembly moves upwards to reset; when the two cams 305 rotate clockwise from 180° to 270°, the upper filter assembly moves upwards; when the two cams 305 rotate clockwise from 270° to 360°, the upper filter assembly moves downwards to reset. In summary, the two cams 305 rotate 360°, enabling the two filter components to move up and down. Furthermore, the vertical movement of the two filter components is alternating and will not hinder or affect each other.

[0100] like Figure 12 As shown, when the filter assembly does not move up and down, or when the filter assembly is being installed and / or disassembled, the vibration assembly does not work, the cam 305 does not rotate, the first cam 3051 and the second cam 3052 are in a horizontal lateral state, and the distance X between the two filter assemblies is greater than the diameter of the first cam 3051, thereby avoiding the cam 305 from obstructing the installation and disassembly of the two filter assemblies.

[0101] When the vibration assembly is working, cam 305 rotates from a horizontal to a vertical position, maximizing the upward and / or downward movement of the filter assembly. This maximum distance is Y, where Y is the sum of the distance between the centers of the first cam 3051 and the second cam 3052, and the radius of the second cam 3052. The difference between the height H of the gap groove 503 and the height T of the convex plate 204 is greater than the maximum distance Y, ensuring that the convex plate 204 can move effectively up and down within the gap groove 503, thus preventing the gap groove 503 from obstructing or restricting the vertical movement of the filter assembly.

[0102] Two cams 305 are connected to each rotating shaft 301. The two cams 305 are located at both ends of the rotating shaft 301, and the two cams 305 correspond to the two second frames 2012 respectively. By setting two cams 305, the filter assembly can be moved smoothly and effectively upward and / or downward.

[0103] In this application, the top of the upper filter component is provided with two elastic components, which correspond to the two second borders 2012 respectively; the bottom of the lower filter component is provided with two elastic components, which correspond to the two second borders 2012 respectively.

[0104] The elastic component is installed inside the housing 101. The elastic component includes a crossbar 401 fixed on the top wall and / or bottom wall of the housing 101. Multiple connecting posts 402 are fixed at equal intervals on the crossbar 401. A buffer spring 403 is provided inside the connecting post 402. The end of the buffer spring 403 is provided with a top post 404. The top post 404 extends out of the connecting post 402 and contacts the second frame 2012.

[0105] The connecting column 402 is a hollow column structure with an opening. One end of the buffer spring 403 is fixed inside the connecting column 402, and the other end of the buffer spring 403 is fixedly connected to the top column 404. The top column 404 can move up and down inside the connecting column 402.

[0106] The elastic component can provide support and buffer reset for the filter component. Specifically:

[0107] like Figure 12 As shown, when the filter assembly does not move up and down, the two upper elastic components can cause the bottom surfaces of the two protrusions 204 of the upper filter assembly to abut against the bottom surface of the gap groove 503, and the two lower elastic components can cause the top surfaces of the two protrusions 204 of the lower filter assembly to abut against the top surface of the gap groove 503.

[0108] When the upper filter assembly moves upward, it can drive the upper top column 404 to move upward and compress the buffer spring 403. The compressed buffer spring 403 can drive the upper filter assembly to move downward automatically, so that the upper filter assembly can move up and down periodically, thereby effectively vibrating and filtering the concrete building material additive.

[0109] When the lower filter assembly moves down, it can drive the lower top column 404 to move down and compress the buffer spring 403. The compressed buffer spring 403 can drive the lower filter assembly to move up automatically, so that the lower filter assembly can move up and down periodically, thereby effectively vibrating and filtering the concrete building material additive.

[0110] In addition, the compression and rebound of the buffer spring 403 can buffer the up-and-down movement of the filter assembly, allowing the filter assembly to move up and down smoothly and effectively preventing the filter assembly from vibrating violently.

Although this 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
