Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete aggregate proportioning, in particular to a concrete aggregate proportioning device. Background Technique
[0002] Concrete aggregate refers to granular loose materials that play a role of skeleton or filling in concrete. It is divided into coarse aggregate and fine aggregate. Coarse aggregate refers to pebbles, crushed stones, etc., and fine aggregate refers to natural sand, artificial sand, etc. Aggregate with a particle size greater than 4.75 mm is called coarse aggregate, commonly known as stones. The commonly used ones are crushed stones and pebbles. Crushed stone is made from natural rock or rock by mechanical crushing and screening, and is a rock particle with a particle size greater than 4.75 mm.
[0003] During the concrete aggregate batching process, different aggregates need to be put into the concrete. However, during proportioning, the aggregate particle sizes of some concrete recycled materials are large and small, and cannot be kept within a relatively stable range. When there are too many coarse aggregates with a large particle size, segregation is likely to occur during the vibration of the concrete, that is, the coarse aggregates sink and the cement slurry floats, resulting in uneven concrete structure, reduced local strength, and easy formation of cracks on the surface. And the existing proportioning devices cannot crush large aggregates of different grades to keep them within a relatively stable particle size range. Excessive particle size will affect the quality of some specially formulated and specially required concrete. Based on this, a concrete aggregate proportioning device is proposed.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a concrete aggregate proportioning device, including a box body 1, a support plate 4 is fixedly installed on the outer side of the box body 1, a support leg frame 5 is fixedly installed at the bottom of the support plate 4, a discharge pipe 6 is communicated with the bottom of the box body 1, four partition rooms 8 are fixedly installed inside the box body 1, a batching pipe 2 is communicated with the top of each of the four partition rooms 8, a bottom plate 10 is fixedly installed at the bottom of the four partition rooms 8, a diversion cone 21 is fixedly installed at the bottom of the inner cavity of each of the four partition rooms 8, a weighing and metering batching device 9 is communicated with the bottom of the diversion cone 21, a servo motor 11 is fixedly installed at the middle part of the bottom of the bottom plate 10, the output end of the servo motor 11 is drivingly connected with a rotating shaft 13, a support bearing 16 is sleeved on the outer side of the rotating shaft 13, a cross bracket 12 is fixedly installed on the outer side of the support bearing 16, a plurality of groups of crushing knives 14 are fixedly installed on the outer side of the output end of the rotating shaft 13, a diversion frame 18 is movably sleeved inside the box body 1, four spring damping mechanisms 15 are fixedly installed on the outer side of the diversion frame 18, a support frame plate 19 is fixedly installed at the bottom of the four spring damping mechanisms 15, a filter screen 17 is fixedly installed at the bottom of the diversion frame 18, a plurality of vibration motors 22 are fixedly installed on the outer side of the diversion frame 18, two water inlet connecting pipes 7 are fixedly sleeved inside the box body 1, and atomizing nozzles 20 are communicated with the opposite ends of the two water inlet connecting pipes 7.
[0020] The working principle of the above technical solution: When in use, the batching pipe 2 is communicated with the feeding mechanism, and the discharge pipe 6 is communicated with the receiving mechanism. Then, when the aggregate enters the inside of the partition room 8 through the batching pipe 2, after being weighed and proportioned by the weighing and metering batching device 9, it enters the inside of the diversion frame 18. At this time, the servo motor 11 and the vibration motor 22 are started. The servo motor 11 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the crushing knives 14 to rotate to crush the large aggregate. Then, the aggregate falls on the top of the filter screen 17. At this time, the vibration motor 22 applies vibration to the diversion frame 18, and the diversion frame 18 vibrates up and down under the elastic support of the spring damping mechanism 15, so that the unqualified crushed materials falling on the top of the filter screen 17 bounce up and are continuously crushed by the crushing knives 14. The aggregate that meets the filter holes of the filter screen 17 falls to the bottom of the filter screen 17 and is discharged and collected through the discharge pipe 6, which is convenient to crush the recycled aggregate under the proportioning of the same weight but different particle sizes, so that the aggregate is kept within a relatively stable particle size range, which is convenient for auxiliary proportioning operation and convenient for ensuring the quality of concrete.
[0021] In another embodiment, as Figures 1 - 4 shown, the weighing and metering batching device 9 is fixedly installed at the bottom of the bottom plate 10.
[0022] The weighing and metering batching device 9 is installed at the bottom of the bottom plate 10 and is communicated with the diversion cone 21, which is convenient for importing and proportioning the aggregate. This scheme is a demonstration operation and adopts a traditional proportioning system, so the detailed principle is not shown.
[0023] In another embodiment, as Figure 2 shown, the water inlet connecting pipe 7 fixedly penetrates through the box body 1 and extends to the inside of the box body 1. The water inlet connecting pipe 7 and the atomizing nozzle 20 are located at the bottom of the filter screen 17.
[0024] This scheme promotes the particle size of the recycled concrete aggregate to remain within a relatively stable range through the screen and crushing functions, ensuring the quality of the concrete aggregate proportioning. The water inlet connecting pipe 7 is connected to an external water source, and the atomizing nozzle 20 sprays and dusts the aggregate falling inside the box body 1, increasing the utilization of the aggregate and reducing the quality loss caused by dust overflow during the crushing of the aggregate. Overall, the relatively stable range of the aggregate is increased, ensuring the production quality of the recycled concrete aggregate proportioning.
[0025] In another embodiment, as Figure 2 shown, the cross support 12 is fixedly installed on the inner wall of the box body 1. The crushing knives 14 are evenly arranged in a circumferential linear pattern on the outside of the rotating shaft 13. The specification dimensions of the crushing knives 14 are adapted to the specification dimensions of the diversion frame 18.
[0026] The cross support 12 provides support for the support bearing 16, assisting in maintaining the stable operation of the rotating shaft 13 and increasing the stability of the structure. The uniform distribution of the crushing knives 14 facilitates the crushing of the aggregate and stable support. When the aggregate slides down along the diversion frame 18, the larger aggregate is crushed by the crushing knives 14 and thrown onto the inner wall of the diversion frame 18 without contacting the crushing knives 14, while the smaller aggregate slides down along the diversion frame 18 and flows down through the filter screen 17. The larger ones bounce with vibration and are then crushed by the crushing knives 14, thus forming an overall crushing cycle, reducing the situation of multiple crushing of smaller aggregates, so that they fall when they are crushed to meet the aperture of the filter screen 17, avoiding over-crushing.
[0027] In another embodiment, as Figure 2 shown, the support frame plate 19 is fixedly installed inside the box body 1, and the four spring shock absorption mechanisms 15 are symmetrically and evenly distributed in a rectangular pattern on the opposite sides of the box body 1 and the diversion frame 18.
[0028] The support frame plate 19 provides support for the spring shock absorption mechanism 15, facilitating the application of an elastic force to the diversion frame 18, assisting in maintaining relative stability, increasing the structural stability, facilitating the maintenance of the relative stable position of the diversion frame 18, and facilitating vibration.
[0029] In another embodiment, as Figure 2 shown, a control panel 3 is installed on the front surface of the box body 1.
[0030] The control panel 3 adopts a built-in programmable intelligent PCL controller, which is convenient for operation. The output end of the control panel 3 is electrically connected to the input ends of the weighing and metering batching device 9, the servo motor 11, and the vibration motor 22 through wires, increasing the stability of operation automation.
[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
