Detailed implementation manners

[0020] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will further describe the present invention in detail with reference to the drawings and embodiments.

[0021] Figures 1 - 19 As shown, the present application provides a weighing device for concrete building material additives, and the filtering and weighing device can filter and weigh the concrete building material additives.

[0022] The weighing device for concrete building material additives includes a filter box, and a filter component, a vibration component, an elastic component and a mounting component are arranged in the filter box. The vibration component is used to drive the filter component to move up and down, so that the filter component can filter the concrete building material additives added into the filter box. The elastic component can play an elastic buffering and supporting role in the up and down movement of the filter component, so as to enable the filter component to stably and effectively perform periodic up and down movement. The mounting component can realize the installation and disassembly of the filter component in the filter box, and can conveniently and quickly replace the filter component to clean the impurities on the filter component.

[0023] The filter box includes a box body 101. The box body 101 is a hollow structure, and the box body 101 can be in the shape of a cuboid, a cylinder, or other shaped structures, which are not specifically limited here.

[0024] The filter box includes a filter base 102. The filter base 102 is arranged in the box body 101 and is located at the bottom of the box body 101. A channel with an up-and-down through and funnel shape is arranged in the filter base 102 to facilitate the passage of the concrete building material additives.

[0025] In an embodiment of the present application, the box body 101 is in the shape of a cuboid, and the filter base 102 is in the shape of a cuboid. The filter base 102 can be fixedly arranged in the box body 101, or the filter base 102 and the box body 101 are integrally formed, or the filter base 102 is arranged in the box body 101 by other means, which are not specifically limited here.

[0026] A feeding hopper 103 is connected to the top inlet of the box body 101, and the concrete building material additives enter the box body 101 through the feeding hopper 103 and the top inlet of the box body 101. A channel with an up-and-down through and funnel shape is arranged in the feeding hopper 103 to facilitate the passage of the concrete building material additives.

[0027] A metering member 104 and a discharging pipe 105 which are communicated are arranged at the bottom outlet of the box body 101. After being filtered by the filter component, the concrete building material additives enter the metering member 104. A control valve (not shown in the figure) is arranged in the metering member 104. By opening and closing the control valve, the flow of the additives in the metering member 104 can be controlled; when the additives need to be weighed, the control valve can be closed. After the additives are weighed by the metering member 104, the control valve is opened, so that the additives are discharged from the filter box through the discharging pipe 105.

[0028] The metering member 104 can be in the shape of a cuboid. A channel with an up-and-down through and funnel shape is arranged in the metering member 104 to facilitate the passage of the concrete building material additives. The way for the metering member 104 to measure and weigh the concrete building material additives can be a common way in this technical field, which is not specifically limited here.

[0029] The number of filtering components can be multiple. The multiple filtering components are arranged in parallel in the box body 101, and the filtering components correspond to the inlet of the box body 101; the concrete building material additive can be directly dropped onto the filtering components through the feeding hopper for filtering to remove impurities in the concrete building material additive.

[0030] In an embodiment of the present application, the number of filtering components is two. The two filtering components are arranged in parallel and at intervals, and can perform two-stage full filtering on the concrete building material additive.

[0031] The filtering component includes a fixing frame 201. A filter plate 202 is detachably connected inside the fixing frame 201. The filter plate 202 is used for filtering the additive. The filter plate 202 can be a filter plate with a filtering function commonly used in the technical field, and no specific limitation is made here.

[0032] In an embodiment of the present application, the fixing frame 201 is an integral part. The fixing frame 201 is a rectangular frame structure with a hollow interior. The fixing frame 201 includes two parallel first side frames 2011 and two parallel second side frames 2012. Corresponding side frame grooves 2013 are provided on the two parallel first side frames 2011, and the side frame grooves 2013 are arranged along the length direction of the first side frame 2011; side frame openings 2014 are provided on the two parallel second side frames 2012, and the side frame openings 2014 are arranged along the length direction of the second side frame 2012. The projection of the filter plate 202 can be rectangular. The filter plate 202 is inserted through one of the side frame openings 2014, and both sides of the filter plate 202 slide into the fixing frame 201 along the two side frame grooves 2013 until the filter plate 202 completely slides into the fixing frame 201, so that the detachable connection of the filter plate 202 in the fixing frame 201 can be realized.

[0033] Both sides of the filter plate 202 are respectively in contact with the inner side surfaces of the two side frame grooves 2013, which can play a limiting role on the filter plate 202 and prevent the filter plate 202 from shifting and shaking along the direction of the second side frame 2012.

[0034] In the actual use process, the filter plate 202 often has the situation of breakage and blockage. The present application can realize the disassembly and replacement of the filter plate 202 conveniently and quickly, so as to repair and clean the filter plate 202 in time and ensure that the filter plate 202 can play an effective filtering role.

[0035] When the filter plate 202 needs to be disassembled, the filter plate 202 can be slid out of the fixing frame 201, and the connection and disassembly of the filter plate 202 can be realized conveniently and quickly, so that the impurities on the filter plate 202 can be cleaned conveniently and quickly.

[0036] On the surfaces of both of the two first side frames 2011, protruding protective plates 203 are fixed. 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.

[0037] The installation assembly includes a fixed seat 501 and a fixed column 502. The fixed seat 501 and the fixed column 502 are respectively located on both sides of the fixed frame 201. Specifically, the fixed seat 501 and the fixed column 502 are respectively located on the outer sides of the two first side frames 2011. On the corresponding two sides of the fixed seat 501 and the fixed column 502, gap grooves 503 are respectively provided. On the outer sides of the two first side frames 2011, convex plates 204 are respectively fixed. The two convex plates 204 are respectively in clearance fit with the two gap grooves 503.

[0038] The outer sides of the two first side frames 2011 refer to the sides facing away from each other of the two first side frames 2011. The thickness of the convex plate 204 is equal to the thickness of the first side frame 2011. The top surface of the convex plate 204 is flush with the top surface of the first side frame 2011, and the bottom surface of the convex plate 204 is flush with the bottom surface of the first side frame 2011.

[0039] The fixed frame 201, the protective plate 203 and the convex plate 204 can be integrally formed by a processing technology or fixed as a single piece by other means, and no specific limitation is made here.

[0040] As Figure 18 shown, the distance between the two first side frames 2011 is equal to the distance between the inner sides of the fixed seat 501 and the fixed column 501, so that the outer sides of the two first side frames 2011 can respectively be in contact and fit with the inner sides of the fixed seat 501 and the fixed column 501, thereby enabling the filter assembly to be limited in the transverse direction. Therefore, when the fixed seat 501, the filter assembly and the fixed column 502 are combined together, the filter assembly cannot move in the transverse direction. The fixed seat 501 and the fixed column 502 can limit the filter assembly in the transverse direction, preventing the filter assembly from deflecting and vibrating in the transverse direction, thereby avoiding the leakage and overflow of additives.

[0041] As Figure 19 shown, the convex plate 204 is in a convex shape. The protruding edge of the convex plate 204 is fixed on the outer side of the first side frame 2011. The corresponding gap groove 503 is adapted to the shape and structure of the convex plate 204. The convex plate 204 is fitted in the gap groove 503, which can limit the convex plate 204 and effectively prevent the convex plate 204 from disengaging from the gap groove 503. Through the cooperation of the convex plate 204 and the gap groove 503, the filter assembly, the fixed seat 501 and the fixed column 502 can be assembled together.

[0042] As Figure 19As shown, the width a of the convex plate 204 is equal to the width of the clearance groove 503, and the length b of the convex plate 204 is equal to the length of the clearance groove 503, which enables the outer side surface and the two outer end faces of the convex plate 204 to be respectively in contact and fit with the inner side surface and the two inner end faces of the clearance groove 503, so that the convex plate 204 can be stably and effectively fitted in the clearance groove 503, effectively preventing the convex plate 204 from detaching from the clearance groove 503. Therefore, when the fixing base 501, the filtering component and the fixing column 502 are combined together, the filtering component cannot move horizontally, and the fixing base 501 and the fixing column 502 can limit the filtering component horizontally, preventing the filtering component from deflecting and vibrating horizontally, thereby avoiding the leakage of additives.

[0043] As Figure 12 , Figure 13 and Figure 14 shown, the height T of the convex plate 204 is less than the height H of the clearance groove 503, which can provide a clearance for the up-and-down movement of the convex plate 204; the convex plate 204 moves up and down in the clearance groove 503, and the clearance groove 503 can limit the up-and-down movement of the convex plate 204 to prevent the filtering component from shifting and falling. At the same time, through the contact and fit between the convex plate 204 and the clearance groove 503, the filtering component cannot move horizontally, and the up-and-down movement of the filtering component can be limited vertically, ensuring the effective up-and-down movement of the filtering component vertically and preventing the filtering component from shifting and tilting.

[0044] A lubricating grease layer (not shown in the figure) can be applied to the inner surface of the clearance groove 503, thereby reducing the friction between the convex plate 204 and the clearance groove 503 and enabling the filtering component to move up and down smoothly and effectively.

[0045] In an embodiment of the present application, the protective plate 203 is an integral part. The protective plate 203 includes a first protective plate 2031 vertically fixed to the surface of the first frame 2011. Second protective plates 2032 are respectively vertically fixed at both ends of the first protective plate 2031. The second protective plates 2032 are vertically fixed to the surface of the first frame 2011. A third protective plate 2033 is 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. Both the first protective plate 2031 and the third protective plate 2033 are arranged along the length direction of the first frame 2011. The first protective plate 2031, the second protective plates 2032 and the third protective plate 2033 form a groove structure with an opening facing the clearance groove 503.

[0046] As Figure 12 , Figure 13 and Figure 14As shown, in an embodiment of the present 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 convex plate 204. When the filter assembly does not move up and down, the third protective plate 2033 and the two second protective plates 2032 can be in contact with the inner side surface of the fixed seat 501 and / or the inner side surface of the fixed column 502, so as to block the gap groove 503, and prevent the concrete building material additive 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 surface of the fixed seat 501 and / or the inner side surface of the fixed column 502, the filter assembly can also be limited in the horizontal direction, so that the filter assembly cannot move in the horizontal direction.

[0047] In an embodiment of the present application, the inner side surfaces of the fixed seat 501 and the fixed column 502 refer to the corresponding side surfaces of the fixed seat 501 and the fixed column 502.

[0048] In an embodiment of the present application, since the number of filter assemblies is two, two vertically parallel gap grooves 503 are provided on the corresponding fixed seat 501, the number of fixed columns 502 is two, and the two fixed columns 502 are arranged vertically and parallel at intervals. Both of the two fixed columns 502 are provided with gap grooves 503; both of the two fixed columns 502 are located on the same side of the two filter assemblies, and the gap grooves 503 of the two fixed columns 502 are in clearance fit with the convex plates 204 of the two filter assemblies respectively; the fixed seat 501 is located on the other side of the two filter assemblies, and the two gap grooves 503 on the fixed seat 501 are in clearance fit with the convex plates 204 of the two filter assemblies respectively.

[0049] The installation assembly further includes a hollow column 504 fixed on the outer wall of the box body 101. The hollow column 504 is in the shape of a cuboid and is vertically fixed on the outer wall of the box body 101. A partition 512 is provided inside the hollow column 504. The partition 512 divides the inside of the hollow column 504 into an upper inner cavity with an upward opening and a lower inner cavity with a downward opening. Limiting springs 506 are provided in both the upper inner cavity and the lower inner cavity. One end of the limiting spring 506 is in contact with the partition 512, and a push plate 505 is fixed at the other end. 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.

[0050] An insertion rod 508 is fixed on the outer side of the fixed column 502, and a limiting groove 509 is provided inside the insertion 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 horizontal direction in the filter box.

[0051] The insertion rod 508 protrudes and is fixed on the outer side of the fixed column 502. The insertion rod 508 can be integrally formed with the fixed column 502 or fixed together by other means, and no specific limitation is made here.

[0052] As Figure 11 , Figure 12 , Figure 13 and Figure 15 shown, in an embodiment of the present application, one side of the limiting block 507 facing the fixed column 502 is an inclined surface 5071. The included angle between the inclined surface 5071 and the vertical direction is an acute angle, and the included angle between the inclined surface 5071 and the horizontal direction is an acute angle. By setting the inclined surface 5071, it is convenient for the limiting block 507 to enter and exit the limiting groove 509, and the locking and unlocking of the fixed column 502 can be achieved conveniently and quickly; in addition, when the limiting block 507 is fitted in the limiting groove 509, it can play a stable and effective locking and limiting role on the fixed column 502.

[0053] The limiting groove 509 is vertically penetrated and arranged in 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. An inclined groove surface (not shown in the figure) parallel to the inclined surface 5071 is provided in the limiting groove 509. When the limiting block 507 is fitted in the limiting groove 509, the inclined surface 5071 and the inclined groove surface are in contact with each other.

[0054] As Figure 11 and Figure 15 shown, in an embodiment of the present application, one side of the limiting block 507 facing the fixed column 502 is an inclined surface. The included angle between the inclined surface and the vertical plane is an acute angle, and the included angle between the inclined surface and the horizontal plane is an acute angle. By setting the inclined surface, it is convenient for the limiting block 507 to enter and exit the limiting groove 509, and the locking and unlocking of the fixed column 502 can be achieved conveniently and quickly; in addition, when the limiting block 507 is fitted in the limiting groove 509, it can play a stable and effective locking and limiting role on the fixed column 502.

[0055] As Figure 11 and Figure 15 shown, in an embodiment of the present application, a driving slider 510 is provided on the outer side of the push plate 505. A through hole 511 is provided on the hollow column 504. The through hole 511 is rectangular and vertically arranged; the driving slider 510 extends out of the through hole 511, and the driving slider 510 can slide up and down in the through hole 511 in a sliding fit; the driving slider 510 can slide up and down along the through hole 511, and by sliding the driving slider 510 up and down, the push plate 505 and the limiting block 507 can be driven to slide up and down conveniently and quickly.

[0056] The limiting spring 506 can reset the limiting block 507, enabling the upwardly and / or downwardly moved limiting block 507 to automatically reset, so that the locking and unlocking of the fixing column 502 can be achieved conveniently and quickly, and further the installation and disassembly of the filtering component can be achieved conveniently and quickly.

[0057] 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, enabling effective compression and / or resilient reset of the limiting spring 506, and no specific limitation is made here.

[0058] The push plate 505, the limiting block 507 and the driving slider 510 can be fixed as an integral part, and no specific limitation is made here.

[0059] A plurality of insertion rods 508 are fixedly arranged at equal intervals on the outer side surface of the fixing column 502, and the number of corresponding hollow columns 504 is also a plurality; one hollow column 504 cooperates with the upper and lower fixing columns 502 at the same time. Among them, the limiting block 507 at the top of the hollow column 504 cooperates with the insertion rod 508 of the upper fixing column 502, and the limiting block 507 at the bottom of the hollow column 504 cooperates with the insertion rod 508 of the lower fixing column 502. Through the cooperation of the plurality of insertion rods 508 and the hollow columns 504, stable and effective locking and unlocking of the fixing column 502 can be achieved.

[0060] An opening 106 corresponding to the fixing seat 501 and an opening 107 corresponding to the insertion rod 508 are provided on the box wall of the box body 101, and the opening 106 and the opening 107 are respectively arranged on two corresponding box walls of the box body 101.

[0061] The opening 106 can be rectangular so that the opening 106 is adapted to the fixing seat 501, and the fixing seat 501 is in clearance fit in the opening 106. The four right angles of the opening 106 are provided with rounded corner structures, which can facilitate the entry and exit of the fixing seat 501.

[0062] The number of the openings 107 is equal to the number of the insertion rods 508, and the insertion rod 508 can extend out of the opening 106 so that the limiting groove 509 on the insertion rod 508 can cooperate with the limiting block 507.

[0063] The installation component of the present application can install and disassemble the filtering component. Specifically: The process of disassembling the filter assembly includes: pushing the driving sliders 510 to slide, where the upper driving slider 510 slides downward and the lower driving slider 510 slides upward, so that the upper limiting block 507 moves downward and disengages from the limiting groove 509 of the upper fixing column 502, and the lower limiting block 507 moves upward and disengages from the limiting groove 509 of the lower fixing column 502. Furthermore, the locking of the upper and lower fixing columns 502 can be released, that is, the unlocking of the fixing columns 502, the filter assembly, and the fixing base 501 as a whole can be achieved. Pull the fixing base 501 outward so that the fixing base 501 disengages from the box body 101. During the outward movement of the fixing base 501, the two fixing columns 502 and the two filter assemblies can be synchronously driven to move outward, so that the two fixing columns 502, the two filter assemblies, and the fixing base 501 are simultaneously moved out of the box body 101 through the opening 106, and the disassembly of the filter assembly can be realized.

[0064] The process of installing the filter assembly includes: placing the fixing base 501 and the two fixing columns 502 on both sides of the two filter assemblies respectively, inserting the convex plates 204 on both sides of the filter assembly into the clearance grooves 503 of the fixing base 501 and the clearance grooves 503 of the fixing columns 502 respectively, and combining the two fixing columns 502, the two filter assemblies, and the fixing base 501 together in the horizontal direction. Insert the combined fixing columns 502, filter assemblies, and fixing base 501 into the box body 101 through the opening 106 until the insertion rods 508 on the fixing columns 502 extend out of the opening holes 107, the filter assemblies extend into the box body 101, and the fixing base 501 is fitted in the opening 106.

[0065] When the fixing column 502 extends into the box body 101, push the driving sliders 510 to slide towards each other, so that the two limiting springs 506 are in a compressed state, and the two limiting plates 507 retract into the inner cavity of the hollow column 504 to prevent the limiting plates 507 from obstructing the extension of the insertion rod 508 out of the opening hole 107. After the insertion rod 508 extends out of the opening hole 107, release the two driving sliders 510, and the two limiting springs 506 stretch and reset, and at the same time, the upper driving slider 510 can be driven to slide upward and the lower driving slider 510 can be driven to slide downward, so that the upper limiting block 507 moves upward and extends into the limiting groove 509 of the upper fixing column 502, and the lower limiting block 507 moves downward and extends into the limiting groove 509 of the lower fixing column 502. Furthermore, the upper and lower fixing columns 502 can be locked, and the combined two fixing columns 502, two filter assemblies, and fixing base 501 can be installed on the box body 101.

[0066] A handle 513 is fixed on the outer side of the fixing base 501. By holding the handle 513 with the hand, the movement of the fixing base 501 can be facilitated, and thus the installation and disassembly of the filter assembly can be facilitated.

[0067] The vibration assembly is arranged between two adjacent filter assemblies and is used to drive the filter assemblies to move up and down.

[0068] The vibration assembly includes two rotation shafts 301 arranged in parallel. The two rotation shafts 301 are rotatably arranged between two filter plates 202.

[0069] Both ends of the two rotation shafts 301 extend out of the box body 101. One end of each of the two rotation shafts 301 is connected with a gear 302. A meshing wheel 303 is meshingly connected between the two gears 302. The two gears 302 and the meshing wheel 303 are all located outside the box body 101. The rotation directions of the two gears 302 are opposite to the rotation direction of the meshing wheel 303, so that the two rotation shafts 301 can rotate in the same direction. For example, the rotation directions of the two gears 302 are counterclockwise and the rotation direction of the meshing wheel 303 is clockwise; or, the rotation directions of the two gears 302 are clockwise and the rotation direction of the meshing wheel 303 is counterclockwise. Specific limitations are not made here.

[0070] The extended end of one of the rotation shafts 301 is connected with a motor 304. The motor 304 is located outside the box body 101. The motor 304 can drive this rotation shaft 301 to rotate. Through the connection of the two gears 302 and the meshing wheel 303, the other rotation shaft 301 can be driven to rotate synchronously, and the rotation directions of the two rotation shafts 301 are the same.

[0071] A cam 305 is fixed on the rotation shaft 301. Through the rotation of the rotation shaft 301, the rotation of the rotation cam 302 can be driven. Through the rotation of the cam 305, the filter assembly can be driven to move up and down.

[0072] The rotation shaft 301 and the cam 305 can be integrally formed or connected into one body by a common fixing method in the art. Specific limitations are not made here.

[0073] The cam 305 is an integral part. The cam 305 includes 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. The rotation shaft 301 penetrates and connects the center of the first cam 3051.

[0074] The orientations of the second cams 3052 on the two rotation shafts 301 are opposite. The cams 305 of the two rotation shafts 301 can rotate synchronously with the rotation shafts 301, and the rotation directions are the same. As Figure 12As shown, assuming that the rotation directions of the rotating shafts 301 are all clockwise, the rotation directions of the cams 305 are also all clockwise. When rotating clockwise for one full circle of 360°, the cam 305 on the left rotates 90° clockwise, which can drive the upper filter assembly to move upward; at the same time, the cam 305 on the right rotates 90° clockwise, which can drive the lower filter assembly to move downward. When the cam 305 on the left rotates clockwise from 90° to 180°, the upper filter assembly moves downward and resets; at the same time, when the cam 305 on the right rotates clockwise from 90° to 180°, the lower filter assembly moves upward and resets. When the cam 305 on the left rotates clockwise from 180° to 270°, it can drive the lower filter assembly to move downward; at the same time, when the cam 305 on the right rotates clockwise from 180° to 270°, it can drive the upper filter assembly to move upward. When the cam 305 on the left rotates clockwise from 270° to 360°, the lower filter assembly moves upward and resets; at the same time, when the cam 305 on the right rotates clockwise from 270° to 360°, the upper filter assembly moves downward and resets. In summary, when the two cams 305 rotate 360°, the up and down movement of the two filter assemblies can be achieved, and the vertical movement of the two filter assemblies is synchronous.

[0075] In other preferred embodiments, the orientations of the second cams 3052 on the two rotating shafts 301 are the same. The cams 305 on the two rotating shafts 301 can rotate synchronously with the rotating shafts 301, and the rotation directions are the same. Assuming that the orientations of the second cams 3052 all face the fixed seat 501 and the rotation directions of the rotating shafts 301 are all clockwise, the rotation directions of the cams 305 are also all clockwise. When rotating clockwise for one full circle of 360°, the two cams 305 rotate 90° clockwise, which can drive the lower filter assembly to move downward; when the two cams 305 rotate clockwise from 90° to 180°, the lower filter assembly moves upward and resets; when the two cams 305 rotate clockwise from 180° to 270°, they can drive the upper filter assembly to move upward; when the two cams 305 rotate clockwise from 270° to 360°, the upper filter assembly moves downward and resets. In summary, when the two cams 305 rotate 360°, the up and down movement of the two filter assemblies can be achieved, and the vertical movement of the two filter assemblies is alternating and will not interfere with each other.

[0076] As Figure 12 shown, when the filter assembly does not move up and down, or when the filter assembly is in the process of installation and / or disassembly, 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 state, and the distance X between the two filter assemblies is greater than the diameter of the first cam 3051, so as to avoid the cam 305 interfering with the installation and disassembly of the two filter assemblies.

[0077] When the vibration component works, the cam 305 rotates from the horizontal transverse state to the vertical state, which can make the maximum distance of the up and / or down movement of the filtering component, and the maximum distance is Y. Y is the sum of the center distance between 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 clearance groove 503 and the height T of the convex plate 204 is greater than the maximum distance Y, so as to ensure that the convex plate 204 can move up and down effectively in the clearance groove 503 and prevent the clearance groove 503 from hindering and restricting the up and down movement of the filtering component.

[0078] Two cams 305 are connected to each rotating shaft 301. The two cams 305 are respectively located at both ends of the rotating shaft 301 and correspond to the two second side frames 2012 respectively. By setting the two cams 305, the smooth and effective up and / or down movement of the filtering component can be ensured.

[0079] In this application, two elastic components are provided at the top of the upper filtering component, and the two elastic components correspond to the two second side frames 2012 respectively; two elastic components are provided at the bottom of the lower filtering component, and the two elastic components correspond to the two second side frames 2012 respectively.

[0080] The elastic component is arranged in the box body 101. The elastic component includes a cross bar 401 fixed on the top wall and / or bottom wall of the box body 101. A plurality of connecting columns 402 are fixed at equal intervals on the cross bar 401. A buffer spring 403 is arranged in the connecting column 402; a top column 404 is arranged at the end of the buffer spring 403. The top column 404 extends out of the connecting column 402 and contacts the second side frame 2012.

[0081] The connecting column 402 is a hollow column structure with an opening. One end of the buffer spring 403 is fixed in the connecting column 402. The other end of the buffer spring 403 is fixedly connected with the top column 404, and the top column 404 can move up and down in the connecting column 402.

[0082] The elastic component can play a role in supporting, buffering and resetting the filtering component. Specifically: As Figure 12 shown, when the filtering component does not move up and down, the two upper elastic components can make the bottom surfaces of the two convex plates 204 of the upper filtering component contact the bottom surface of the clearance groove 503, and the two lower elastic components can make the top surfaces of the two convex plates 204 of the lower filtering component contact the top surface of the clearance groove 503.

[0083] When the upper filtering component moves up, it can drive the upper top column 404 to move up and compress the buffer spring 403. The compressed buffer spring 403 can drive the upper filtering component to move down automatically, so that the upper filtering component can move up and down periodically, and thus can effectively vibrate and filter the concrete building material additive.

[0084] When the lower filtering component moves downward, it can drive the lower top column 404 to move downward and compress the buffer spring 403. The compressed buffer spring 403 can drive the lower filtering component to move upward automatically, so that the lower filtering component can move upward and downward periodically, thereby effectively vibrating and filtering the concrete building material additive.

[0085] In addition, through the compression and rebound of the buffer spring 403, the up and down movement of the filtering component can be buffered, so that the filtering component can move up and down smoothly, effectively avoiding violent vibration of the filtering component.

[0086] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, it is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions required to be protected by the present invention.
