Description

Technical Field

[0001] The present invention relates to the technical field of concrete raw material storage, in particular to a concrete raw material storage device for recycling construction waste. Background Art

[0002] During the construction process of a building project, design changes frequently occur due to various reasons such as owner requirements and design defects, making some of the purchased or processed building materials unable to adapt to the new design plan, thereby generating a large amount of waste.

[0003] In order to avoid the waste of these wastes, they need to be recycled and utilized. First, the construction waste should be preliminarily cleaned to remove debris such as wood, plastic, paper, metal, etc., and then the larger pieces of construction waste such as bricks, concrete blocks, etc. after sorting should be crushed by jaw crushers, impact crushers and other equipment to make them into smaller particles. The crushing process can be carried out multiple times as needed to achieve the required aggregate particle size requirements. Since aggregate is the raw material of concrete, the crushed aggregate is poured into the concrete raw material storage bin for storage.

[0004] The existing aggregate storage is to store a variety of aggregates with different particle sizes and densities together. Since aggregates of different particle sizes have their own appropriate uses, such as coarse aggregates are used to provide strength skeletons, and fine aggregates are used to fill gaps, it is impossible to accurately obtain the required particle size aggregates after mixing, which affects the mix ratio design and performance of materials such as concrete. In addition, aggregates of different densities are mixed together, which is difficult to accurately distinguish and weigh, resulting in increased batching errors and inability to accurately batch according to the designed mix ratio, affecting the quality of concrete.

[0005] Therefore, it is necessary to design a concrete raw material storage device for recycling construction waste that can differentiate and store aggregates of different particle sizes and densities. Summary of the Invention

By setting up screening plates and feeding components respectively, the incoming aggregates are effectively divided into large and small particle sizes and transported in sequence. Then, according to the principle that the greater the density of aggregates with different densities in the same volume space, the heavier the weight, the box can accurately judge whether the inside of the box is light aggregate, ordinary aggregate, or heavy aggregate, and then send it to the corresponding storage area for storage. This effectively prevents aggregates of different densities from being mixed together, making it difficult to accurately distinguish and weigh them, resulting in increased batching errors, and the inability to accurately batch according to the designed mix ratio, which affects the quality of concrete. The effect of automatically distinguishing aggregate particle size and density for storage is achieved.

[0017] 2. After the aggregate inside the feeding box is discharged, the feeding box is ejected by the spring, which not only drives the feeding box back to its original position to transport the next batch of aggregate, but also drives the T-shaped block to slide along the slide. While sliding, it drives the gear above to rotate rapidly, and then indirectly drives the fan to rotate rapidly. The wind force generated by the rapid rotation of the fan passes through the air outlet and blows away some of the aggregate stuck in the edge corners of the slide, effectively preventing too much aggregate from being stuck in the edge corners, causing the subsequent sliding aggregate to accumulate in the position where the aggregate is stuck.

[0027] See also Figure 4The small particle size distinguishing mechanism 7 and the large particle size distinguishing mechanism 8 have the same structure. The large particle size distinguishing mechanism 8 includes a slide plate 82 fixedly connected to the inside of the storage bin 1. A collection trough 83 is provided on one side of the slide plate 82. Anti-stuck components 81 are provided on both sides of the slide plate 82 for blowing away aggregates stuck at the angles on both sides. A material passing component 85 is provided on the lower side of the collection trough 83. A feeding component 86 is provided on one side of the material passing component 85. A discharging component 87 is provided on the lower side of the feeding component 86. Guide slide plates 84 are provided on both sides of the feeding component 86, one of which is fixedly connected to the storage bin 1, and the other is fixedly connected to the Z-shaped partition 6.

[0028] The specific description based on the above structure is as follows: the large-size aggregate and the small-size aggregate screened by the screening plate 5 respectively arrive above the slide plate 82 on both sides of the Z-shaped partition 6, and are differentiated by the density of the feeding component 86, so that the aggregates of different densities are transported to different areas for storage.

[0029] See also Figure 7 and Figure 9 The feeding assembly 86 includes a slider 863 slidably connected to the inside of the guide slide 84, a feeding box 865 is fixedly connected to one side of the slider 863, a level sensor 864 is fixedly connected to the upper side of the feeding box 865, a plurality of springs 861 are fixedly connected to one side of the feeding box 865, a fixed plate 862 is fixedly connected to the other side of the plurality of springs 861, and the fixed plate 862 is fixedly connected to the storage bin 1, a solenoid valve 866 is fixedly connected to the upper side of the other side of the feeding box 865, two first electric push rods 867 are evenly fixedly connected to one side of the feeding box 865, and the output end of each first electric push rod 867 is fixedly connected to a friction plate 868, and the two sides of the feeding box 865 are hinged to the two second connecting rods 812 respectively.

[0030] The above structure is described in detail as follows: Spring 861 supports feed box 865 and the aggregate inside, preventing it from sliding downward. The force of spring 861 can be adjusted based on the actual aggregate particle size and density. Level sensor 864 can be an ultrasonic level meter, which measures the aggregate level by transmitting and receiving ultrasonic waves. The ultrasonic level meter's probe is mounted on the top of the box and transmits ultrasonic pulses toward the aggregate surface. The ultrasonic waves are reflected by the surface and received by the probe. The level meter calculates the distance between the aggregate surface and the probe based on the time difference between the transmission and reception of the ultrasonic waves, thereby determining the aggregate level. When the aggregate level reaches the full height of the box, a full signal is issued, and the output end of the first electric push rod 867 extends to control the friction plate 868 to press against the guide plate 84. When the friction between the friction plate 868 and the guide plate 84 exceeds the force of spring 861, the feed box 865, if the aggregate has not completely fallen out, cannot be ejected back into place.

[0031] See also Figure 8 The material passing assembly 85 includes a feed pipe 854 fixedly connected to the lower side of the collecting trough 83, and the lower side of the feed pipe 854 is penetrated by a third discharge pipe 853, the interior of the third discharge pipe 853 is slidingly connected to the second discharge pipe 852, and the interior of the second discharge pipe 852 is slidingly connected to the first discharge pipe 851, and the other end of the first discharge pipe 851 is fixedly connected to the input end of the solenoid valve 866, and both ends of the first discharge pipe 851, the second discharge pipe 852 and the third discharge pipe 853 are chamfered.

[0032] The specific description based on the above structure is as follows: the aggregate enters the interior of the feed box 865 through the feed pipe 854, the third discharge pipe 853, the second discharge pipe 852, and the first discharge pipe 851 in sequence. When the feed box 865 slides along the guide slide 84, the third discharge pipe 853, the second discharge pipe 852, and the first discharge pipe 851 can be freely extended and retracted.

[0033] See also Figure 10 The discharge assembly 87 includes a material passing block 871 fixedly connected to the lower side of the feed box 865, one side of the material passing block 871 is fixedly connected to a second electric push rod 874, the output end of the second electric push rod 874 is fixedly connected to a connecting block 873, one side of the connecting block 873 is fixedly connected to a material blocking plate 872, and the material blocking plate 872 is slidably connected to the material passing block 871.

[0034] The specific description based on the above structure is as follows: the extension of the output end of the second electric push rod 874 is used to control the sliding of the material blocking plate 872, thereby opening the outlet below the material block 871, so that the aggregate is sent to the area with the corresponding density for storage.

[0035] When the conveying equipment conveys the aggregate to the interior of the storage bin 1, the aggregate is screened by the screening plate 5 and respectively passed into the two sides of the Z-shaped partition 6. The small-sized aggregate falls onto the slide 82 on the right side of the Z-shaped partition 6, and the large-sized aggregate falls onto the slide 82 on the left side of the Z-shaped partition 6, and enters the interior of the aggregate trough 83 along the slide 82. Since the gravity of the feeding assembly 86 is much smaller than the elastic force of the spring 861, the spring 861 is fully ejected in the initial state, and the second discharge pipe 852 and the first discharge pipe 851 are retracted into the interior of the third discharge pipe 853. The aggregate passes through the aggregate trough 83 in sequence through the feed pipe 854, the third discharge pipe 853, the second discharge pipe 852, and the first discharge pipe 851. The solenoid valve 866 is opened, and the aggregate continues to slide into the interior of the feed box 865. The level sensor 864 emits ultrasonic waves downward in real time to monitor the stacking height of the aggregate. When the level sensor 864 detects that the feed box 865 is fully loaded, it sends a full signal to the controller 3. The controller 3 controls the output end of the second electric push rod 874 to extend the control baffle plate 872 to slide, thereby opening the outlet below the material passing block 871.

[0036] When the incoming aggregate is light aggregate, since the gravity of the feeding box 865 filled with light aggregate is less than the initial elastic force of the spring 861, the spring 861 does not deform and still maintains its original length. The position of the feeding box 865 remains unchanged, and the aggregate passes through the material block 871 and falls into the interior of the third weighing box 93 for storage.

[0037] When the incoming aggregate is ordinary aggregate, since the gravity of the feeding box 865 filled with ordinary aggregate is greater than the initial elastic force of the spring 861, in static equilibrium, the spring 861 is continuously compressed, driving the feeding box 865 to slide diagonally downward until its elastic force is balanced with the gravity of the feeding box 865 filled with ordinary aggregate. At this time, the spring 861 is in a semi-compressed state, and the feeding box 865 slides to the top of the second weighing box 92. The aggregate passes through the material block 871 and falls into the interior of the second weighing box 92 for storage.

[0038] When the incoming aggregate is heavy aggregate, since the gravity of the feed box 865 filled with heavy aggregate is much greater than the initial elastic force of the spring 861, the spring 861 is continuously compressed until its elastic force is balanced with the gravity of the feed box 865. At this time, the spring 861 is compressed to the extreme position, and the feed box 865 slides to the top of the first weighing box 91. The aggregate passes through the material block 871 and falls into the interior of the first weighing box 91 for storage.

[0039] In order to prevent the aggregate from falling, the gravity of the feed box 865 gradually decreases, and the spring 861 begins to rebound before the aggregate has completely fallen. Therefore, when the level sensor 864 detects that the feed box 865 is fully loaded, the controller 3 controls the output end of the first electric push rod 867 to extend, and controls the friction plate 868 to press the guide slide 84. Since the friction force between the friction plate 868 and the guide slide 84 is greater than the elastic force of the spring 861, the feed box 865 where the aggregate has not completely fallen will not be ejected back until the level sensor 864 detects that all the aggregate inside the feed box 865 has finished falling. The controller 3 controls the output end of the first electric push rod 867 to retract. At this time, the friction plate 868 no longer presses the guide slide 84, and the feed box 865 is driven by the spring 861 to return.

[0040] The method for distinguishing the density of small-size aggregates is the same as that for large-size aggregates, and will not be repeated here.

[0041] When aggregate needs to be used, the staff only needs to open the corresponding discharge valve 97.

[0042] By respectively arranging the screening plate 5 and the feeding assembly 86, the incoming aggregates are effectively divided into large-size and small-size particles and conveyed in sequence. Then, based on the principle that the greater the density of aggregates with different densities in the same volume space, the heavier the weight, the box body can accurately judge whether the aggregates inside are light aggregates, ordinary aggregates, or heavy aggregates, and then convey them to the corresponding storage area for storage. This effectively prevents aggregates of different densities from being mixed together, making it difficult to accurately distinguish and weigh them, resulting in increased batching errors, and the inability to accurately batch according to the designed mix ratio, which affects the quality of concrete. The effect of automatically distinguishing the aggregate particle size and density for storage is achieved.

[0043] In the second embodiment, since the aggregate particles have complex shapes, sharp edges or flat surfaces, and fall on the edge of the slide 82, they are easily stuck with the edge corners of the slide 82 during the falling or sliding process, which prevents them from continuing to slide. If the residual aggregate stuck in the edge corners of the slide 82 is not cleaned regularly, the aggregate accumulation will increase over time, resulting in more aggregate stuck in the edge corners, and most of the residual aggregate will be moved by aggregates of different densities in the future, thereby causing the two aggregates of different densities to be mixed and stored together, affecting the precise batching of the subsequent concrete. Therefore, the following structure is designed to solve the above technical problems.

[0044] See also Figure 4-Figure 6 The anti-stuck component 81 includes a positioning plate 813 fixedly connected to both sides of the slide plate 82, and each positioning plate 813 is provided with a plurality of air outlet holes 814 on the upper side, and a slide groove 816 is provided on the lower side of the positioning plate 813. The inner wall of the positioning plate 813 is evenly provided with a plurality of tooth columns 815, and the inner side of the slide groove 816 is slidably connected to a T-shaped block 819, and the upper side of the T-shaped block 819 is rotatably connected to a gear 818, and the gear 818 is meshed with the tooth column 815. The upper side of the gear 818 is fixedly connected to a fan 817 through a connecting shaft, and the lower side of the T-shaped block 819 is hinged with a first connecting rod 811, and the other end of the first connecting rod 811 is hinged with a second connecting rod 812.

[0045] The specific description based on the above structure is as follows: when the feed box 865 returns to its position to distinguish the density of the next batch of aggregates, the feed box 865 slides and drives the second connecting rod 812 to move, thereby indirectly driving the first connecting rod 811 to move. The second connecting rod 812 and the first connecting rod 811 are adaptively bent while moving. Since the first connecting rod 811 moves and drives the T-shaped block 819 to slide along the slide groove 816, the gear 818 above is driven to rotate rapidly while sliding, thereby indirectly driving the fan 817 to rotate rapidly. The wind force generated by the rapid rotation of the fan 817 passes through the air outlet 814, thereby blowing away some of the aggregates stuck in the edge corners of the slide plate 82.

[0046] After the aggregate inside the feeding box 865 is discharged, the feeding box 865 is ejected by the spring 861, which not only drives the feeding box 865 to return to its original position to transport the next batch of aggregate, but also drives the T-shaped block 819 to slide along the slide groove 816. While sliding, it drives the gear 818 above to rotate rapidly, and then indirectly drives the fan 817 to rotate rapidly. The wind force generated by the rapid rotation of the fan 817 passes through the air outlet 814, and blows away some of the aggregate stuck in the edge corners of the slide plate 82, effectively preventing too much aggregate from being stuck in the edge corners, causing the subsequent sliding aggregate to accumulate at the position where the aggregate is stuck.
