Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a feeding device for a concrete sand and gravel separator. Background Technology

[0002] A sand and gravel separator is a device used to separate sand and stone aggregates from residual concrete during construction. The separated sand and gravel can be reused to mix concrete, thereby reducing waste and realizing resource recycling.

[0003] Chinese utility model patent CN220596380U discloses a feeding device for a concrete aggregate separator. It includes a main body with a feeding channel and a feeding hopper on the main body. A baffle plate is installed inside the feeding hopper, positioned near the connection between the feeding hopper and the feeding channel, separating the two. The device also includes a drive assembly, comprising a spring mounted on the feeding hopper. The spring abuts against the baffle plate and drives the baffle plate to rotate away from the feeding channel. The drive assembly further includes a movable plate rotatably mounted on the main body and a drive component connected to the movable plate. The movable plate abuts against the baffle plate, and when rotated under the drive assembly, it pushes the baffle plate to rotate closer to the feeding channel. This utility model addresses the technical problem of equipment blockage caused by a large influx of concrete into the feeding hopper, effectively limiting the amount of concrete entering the equipment and preventing blockage, thus improving the stability of equipment operation.

[0004] In the process of realizing this utility model, the technology has at least the following problems: the feeding device cannot control the amount of sand and gravel fed. If a large amount of sand and gravel is fed at one time, it is easy to cause difficulties in screening inside the sand and gravel machine. Therefore, a feeding device for a concrete sand and gravel separator is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for a concrete sand and gravel separator, which has advantages such as controlling the amount of sand and gravel fed. It solves the problem that the feeding device cannot control the amount of sand and gravel fed, and that if a large amount of sand and gravel is fed at one time, it is easy to cause difficulties in screening inside the sand and gravel separator.

[0006] In summary, the present invention provides the following technical solution: a concrete sand and gravel separator feeding device, including a feeding cylinder, a discharge pipe connected to the upper side of the feeding cylinder, a solenoid valve installed on the outer side of the discharge pipe, a sand and gravel storage tank connected to the upper side of the discharge pipe, a moving device provided inside the feeding cylinder, and a feeding device provided inside the feeding cylinder.

[0007] The moving device includes a left-side drive motor fixedly installed inside the feeding cylinder, a threaded rod fixedly connected to the output end of the drive motor, and a threaded sleeve threadedly connected to the outer side of the threaded rod.

[0008] The feeding device includes a feeding box fixedly connected to one side of the threaded sleeve, two electric telescopic rods fixedly installed on the left side of the feeding box, a push plate fixedly connected to the output end of the electric telescopic rods, and four infrared sensors embedded inside the feeding box.

[0009] This utility model, by adopting the above-mentioned technical solution, uses an electric telescopic rod to push the push plate into the corresponding infrared sensor, adjusts the capacity of sand and gravel in the feeding box, and completes the quantity control of sand and gravel feeding.

[0010] Furthermore, a limiting component is provided on one side of the feeding box. The limiting component includes a sliding sleeve fixedly connected to one side of the feeding box and a sliding rod slidably sleeved inside the sliding sleeve.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the sliding sleeve on one side of the feeding box slides on the outside of the sliding rod, thereby achieving the purpose of limiting movement.

[0012] Furthermore, a material blocking assembly is provided on the right side of the feeding box. The material blocking assembly includes a motor fixedly installed on the front end of the feeding box, a rotating shaft fixedly connected to the output end of the motor, and a movable plate sleeved on the outer side of the rotating shaft.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the movable plate can be rotated inside the right side of the feeding box by the motor. During the rotation, the movable plate is limited by the stop block to prevent it from rotating into the feeding box, which would not effectively block the sand and gravel.

[0014] Furthermore, a PLC controller is embedded in the front end face of the feeding cylinder, and a baffle is fixedly connected to the left side inside the feeding cylinder.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the mechanical structure on the outside of the feeding cylinder and the discharge pipe can be controlled by the PLC controller, thereby reducing the output of manpower and ensuring the accuracy of discharge.

[0016] Furthermore, the baffle has two through holes inside that are compatible with the electric telescopic rod, and the two through holes are arranged vertically.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the through hole facilitates the movement of the electric telescopic rod and avoids the baffle from obstructing the electric telescopic rod.

[0018] Furthermore, a laser rangefinder sensor is fixedly installed on the upper side of the feeding box, and a stop block is fixedly connected inside the right side of the feeding box.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, by fixing the output end of the laser rangefinder sensor vertically to the inside of the feeding box, the height of the sand and gravel entering the feeding box can be observed in real time during the sand and gravel discharge, which can effectively prevent the sand and gravel from leaking out.

[0020] Furthermore, a sealing ring, which is a rubber sealing ring, is fixedly sleeved on the outer side of the push plate.

[0021] The beneficial effect of adopting the above-mentioned further solution is that by having the outer side of the sealing ring abut against the inner wall surface of the feeding box, when the push plate moves the sealing ring, it can prevent sand and gravel from accumulating and staying in the feeding box, and can directly push out all the sand and gravel.

[0022] Furthermore, the end of the threaded rod away from the drive motor passes through the baffle and extends to its exterior.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the relative ends of the drive motor are clamped and fixed by the relative surfaces of the feeding cylinder and the baffle, which provides a firm support for the drive motor.

[0024] Compared with the prior art, the present invention provides a feeding device for a concrete sand and gravel separator, which has the following beneficial effects:

[0025] 1. The feeding device of this concrete sand and gravel separator uses an electric telescopic rod to push the push plate into the corresponding infrared sensor, thereby adjusting the capacity of sand and gravel in the feeding box and controlling the quantity of sand and gravel fed.

[0026] 2. The feeding device of this concrete sand and gravel separator uses a laser rangefinder to detect the height of the sand and gravel in the feeding box in real time during the process of the sand and gravel falling into the feeding box, which prevents the sand and gravel from leaking out. At the same time, when discharging, the movable plate rotates into the feeding box and is limited by a stop block to keep the movable plate perpendicular to the inside of the feeding box. This solves the problem that the feeding device cannot control the amount of sand and gravel discharged. If a large amount of sand and gravel is discharged at one time, it will easily cause difficulties in screening inside the sand and gravel machine. Attached Figure Description

[0033] Please see Figure 1 A concrete sand and gravel separator feeding device includes a feeding cylinder 1, a discharge pipe 2 connected to the upper side of the feeding cylinder 1, a solenoid valve 3 installed on the outer side of the discharge pipe 2, a sand and gravel storage tank 4 connected to the upper side of the discharge pipe 2, a moving device inside the feeding cylinder 1, and a feeding device inside the feeding cylinder 1.

[0034] The feed cylinder 1 has a PLC controller 21 embedded in its front end face, a baffle 5 is fixedly connected to the left side inside the feed cylinder 1, and a sealing ring 14 is fixedly sleeved on the outside of the push plate 13. The sealing ring 14 is a rubber sealing ring.

[0035] It should be noted that the PLC controller 21 can control the mechanical structure on the outside of the feeding cylinder 1 and the discharge pipe 2, thereby reducing manual labor and ensuring discharge accuracy. The outer side of the sealing ring 14 abuts against the inner wall surface of the feeding box 9. When the push plate 13 moves the sealing ring 14, it can prevent sand and gravel from accumulating in the feeding box 9 and can directly push out all the sand and gravel. The sealing ring 14 can be selected from natural rubber, nitrile rubber, silicone rubber, fluororubber, and neoprene rubber as needed. Natural rubber has excellent resilience, insulation, water resistance, and plasticity. Nitrile rubber has good chemical stability, outstanding oil resistance, and good processing performance. However, its resilience is reduced and its cold resistance is worse. Silicone rubber has excellent high-temperature resistance, cold resistance, ozone resistance, atmospheric aging resistance, and good insulation performance. However, its tensile strength is lower than that of ordinary rubber, and it lacks oil resistance. Fluororubber is resistant to high temperatures, corrosion, and oil, and has excellent resistance to various chemicals. Chloroprene rubber has good physical and mechanical properties, and is resistant to oil, heat, flame, sunlight, ozone, acids, alkalis, and chemical reagents. However, its cold resistance and storage stability are relatively poor.

[0036] Please see Figure 1 and Figure 4In this embodiment, the moving device includes a left-side drive motor 6 fixedly installed inside the feeding cylinder 1, a threaded rod 7 fixedly connected to the output end of the drive motor 6, and a threaded sleeve 8 threadedly connected to the outer side of the threaded rod 7.

[0037] The threaded rod 7, at the end furthest from the drive motor 6, passes through the baffle 5 and extends to its exterior.

[0038] It should be noted that the opposite ends of the drive motor 6 are clamped and fixed by the opposite surfaces of the feed cylinder 1 and the baffle 5, which provides a firm support for the drive motor 6. The threaded rod 7 is made of stainless steel. Stainless steel threaded rods can be used for a long time in harsh environments and exhibit excellent corrosion resistance. This characteristic allows it to maintain good working condition in humid, acidic and alkaline environments. In addition, stainless steel has high strength and can withstand greater pressure and load. Finally, stainless steel threaded rods can maintain stable performance in high-temperature environments and are not easily deformed or aged.

[0039] Please see Figures 1 to 4 In this embodiment, the feeding device includes a feeding box 9 fixedly connected to one side of the threaded sleeve 8, two electric telescopic rods 12 fixedly installed on the left side of the feeding box 9, an output end push plate 13 fixedly connected to the electric telescopic rods 12, and four infrared sensors 15 embedded inside the feeding box 9.

[0040] The feeding box 9 has a limiting component on one side, which includes a sliding sleeve 20 fixedly connected to one side of the feeding box 9 and a sliding rod 19 slidably sleeved inside the sliding sleeve 20. A baffle assembly is provided on the right side of the feeding box 9, which includes a motor 11 fixedly installed at the front end of the feeding box 9, a rotating shaft 17 fixedly connected to the output end of the motor 11, and a movable plate 18 sleeved on the outer side of the rotating shaft 17. The baffle 5 has two through holes inside that match the electric telescopic rod 12, and the two through holes are arranged vertically. The feeding box 9 is fixedly mounted on the upper side. Equipped with a laser rangefinder 10, a stop block 16 is fixedly connected inside the right side of the feeding box 9. The infrared sensor 15 is usually composed of an infrared receiver, amplifier, filter and control circuit. The infrared sensor 15 emits infrared light through an infrared emitting tube. When a part of the object is in the infrared area, the infrared light is blocked by the push plate 13 and reflected to the infrared receiving tube. The reflected infrared signal is processed by the microcomputer in the integrated circuit and sent to the solenoid valve 3. Then the signal is sent to the PLC controller 21.

[0041] It should be noted that the sliding sleeve 20 on one side of the feeding box 9 slides outside the sliding rod 19 to achieve the purpose of limiting movement. The motor 11 drives the movable plate 18 to rotate inside the right side of the feeding box 9. During rotation, the movable plate 18 is limited by the stop block 16 to prevent it from rotating into the feeding box 9, thus failing to effectively block the sand and gravel. The through hole facilitates the movement of the electric telescopic rod 12 and prevents the baffle 5 from obstructing the electric telescopic rod 12. The output end of the laser rangefinder 10 is fixed vertically to the inside of the feeding box 9. During the sand and gravel discharge, the height of the sand and gravel entering the feeding box 9 can be observed in real time using the output end of the laser rangefinder 10, which can effectively prevent the sand and gravel from leaking out. The laser rangefinder 10 contains a laser emitter and a receiver photodetector. The laser emitter emits a laser pulse. When this laser pulse encounters the surface of the object being measured, it is reflected, and the reflected laser pulse is received by the receiver.

[0042] The working principle of the above embodiments is as follows:

[0043] Sand and gravel are placed into the sand and gravel storage tank 4 until it is full. During feeding, the output end of the electric telescopic rod 12 is controlled to push the push plate 13 within the feeding box 9, based on the required quantity. When the push plate 13 reaches the front face of the infrared sensor 15, the data is displayed in the PLC controller 21 for the operator to view, and the capacity of the feeding box 9 decreases. The push plate 13 is then moved to the corresponding infrared sensor 15 position to stop, and the solenoid valve 3 is controlled again to discharge the sand and gravel into the feeding box 9. As the sand and gravel continuously fill, it reaches the laser rangefinder 1. When the height is set to 0, the laser rangefinder 10 controls the solenoid valve 3 to close the sand and gravel conveying in the sand and gravel storage tank 4 to prevent sand and gravel leakage. Then, the drive motor 6 drives the threaded rod 7 to move the feed box 9 to the right side laterally. The motor 11 rotates to the right and works with the rotating shaft 17 to move the movable plate 18 out. At this time, the sand and gravel fall into the sand and gravel separator without any obstruction on the right side. In order to reduce the amount of sand and gravel remaining in the feed box 9, the electric telescopic rod 12 is activated to push the push plate 13 to push out the remaining sand and gravel. After the discharge is completed, the motor 11 is used to reverse the drive to restore the movable plate 18 to its original position.
