Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and more specifically, to a sand and gravel separator for high-performance concrete production. Background Technology

[0002] Currently, construction sites have a large amount of waste concrete remaining. Sand and gravel separators are typically used to separate the sand and gravel from the concrete. The concrete is poured into the separator, mixed in the feed hopper, and then poured onto a screen. The screen is shaken to separate the sand and gravel. For example, the high-performance concrete production sand and gravel separator described in prior art publication (CN214865135U) involves shaking the screen while separating the sand and gravel from the waste concrete. A motor drives a rotating disc that moves a sliding rod, causing the bottom frame to slide back and forth on a slide rail. This allows the protrusions to move horizontally through the screen holes. The protrusions on the crossbar slide within the screen, scraping away any clogging soil in the screen holes. This effectively prevents soil from clogging the screen, making the separation of sand and gravel more effective. During this process, soil placed on the screen does not accumulate at the pointed ends of the protrusions, and the staggered arrangement of the protrusions ensures asynchronous cleaning of the screen, reducing the probability of jamming.

[0003] However, when the above-mentioned device is in use, the drive mechanism causes the protrusion to move horizontally in the screen holes of the screen. When the bottom frame reciprocates, the elastic component makes it contractile during the movement, making the bottom frame more stable during the sliding process. However, its screening efficiency is slow, and the discharge efficiency is also slow after screening. In response to this situation, a high-performance sand and gravel separator for concrete production is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high-performance sand and gravel separator for concrete production. The technical problem to be solved by this utility model is: how to increase the efficiency of sand and gravel separation and screening and the discharge speed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance concrete production sand and gravel separator, including a sand and gravel separation shell with a support frame at its lower end, a first discharge port on one side of the outer end face of the sand and gravel separation shell, a second discharge port on the side of the outer end face of the sand and gravel separation shell near the first discharge port, a discharge motor on the side end face of the sand and gravel separation shell near the first discharge port, and a separation motor on the side end face of the sand and gravel separation shell near the second discharge port;

[0006] A discharge partition plate is provided on one side of the inner end face of the sand and gravel separation shell.

A separation rotating rod is provided inside the sand and gravel separation shell on the output shaft of the separation motor. An inclined guide plate is provided on the lower side of the inner end face of the sand and gravel separation shell.

[0007] The inner end face of the sand and gravel separator shell is provided with a concave material collection groove on one side of the inclined guide plate. The output shaft of the discharge motor passes through the end face of the sand and gravel separator shell and extends into the interior of the sand and gravel separator shell. The output shaft of the discharge motor is provided with a discharge rotating rod inside the sand and gravel separator shell. The outer end face of the discharge rotating rod is provided with guide blades.

[0008] In a preferred embodiment, the outer end face of the separating rotating rod is provided with a separating support rod, and the outer end face of the separating support rod is provided with a material distribution screen, which is fixedly connected to the separating support rod.

[0009] The inner end face of the material distribution screen cylinder is provided with rotating blades, and the sand and gravel separation shell is provided with a feed hole on the end face away from the separation motor.

[0010] In a preferred embodiment, the number of the separating support rods is multiple, and they are arranged in a ring array outside the center point of the material distribution screen cylinder in the right-view direction. The rotating blades are arranged in a spiral state on the inner end face of the material distribution screen cylinder.

[0011] The separate motor is electrically connected to the external control equipment.

[0012] In a preferred embodiment, the number of support frames is multiple, and they are arranged in an array on both sides of the vertical central axis in the main viewing direction of the sand and gravel separation shell. One end of the material distribution screen is in a constricted state, and one end of the material distribution screen passes through the end face of the discharge partition plate and extends to the other side of the discharge partition plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] In practical use, this invention facilitates the separation of sand and gravel raw materials through the corresponding arrangement of the separating motor, separating rotating rod, separating support rod, material distribution screen, and rotating blades.

With the separation support rod 10 connected to the separation rotating rod 8 and the distribution screen cylinder 11, the distribution screen cylinder 11 will rotate, thereby separating the sand and gravel. At the same time, the small sand and gravel particles after separation will fall onto the upper end of the inclined guide plate 13 and into the concave collection trough 14. Then, when the distribution screen cylinder 11 rotates, the rotating blade 12 will push the sand and gravel, thereby slowly pushing the large sand and gravel particles to one side, thus guiding the large sand and gravel particles to one side of the discharge partition plate 9, so that the separated large sand and gravel particles fall into the upper end of the inclined guide plate 13 and are discharged from the second discharge port 4. Then, the discharge motor 6 drives the discharge rotating rod 15 and the guide blade 16 to rotate, thereby discharging the separated sand and gravel from the inside of the first discharge port 3.
