Description

Technical Field

[0001] This application relates to the field of weighing equipment technology, and in particular to a raw material weighing device for recycled aggregate concrete. Background Technology

[0002] Recycled aggregate concrete refers to concrete made by crushing, washing, and grading waste concrete blocks, broken bricks, and tiles, and then mixing them with cement, water, admixtures, and other components in a certain proportion. It is a green and environmentally friendly building material that can effectively solve the problem of construction waste disposal while reducing the over-exploitation of natural aggregates. The production process of recycled aggregate concrete requires first using a raw material weighing device to weigh the various raw materials in the specified proportions, and then pouring the weighed materials into a mixing device for thorough mixing.

[0003] In related technologies, the raw materials of recycled aggregate concrete are usually weighed separately using a weighing device first, and then the weighed raw materials are transferred to a conveyor belt and transported to the mixing equipment. However, since the weighing and transfer operations of the recycled aggregate concrete raw materials are carried out separately, the operation process is cumbersome, time-consuming and labor-intensive, and the continuity is not high, which will affect the production efficiency of recycled aggregate concrete.

[0004] Therefore, we propose a raw material weighing device for recycled aggregate concrete to solve the above problems. Utility Model Content

[0012] Optionally, the lifting and feeding mechanism includes a lifting box, conveying rollers, a conveyor belt, partition plates, and a motor. The lifting box is fixedly installed on one side of the holding box. A feed hole is provided on the side of the lifting box near the holding box, and the feed hole is connected to the feeding hole.

The output shaft end of the motor extends into the lifting box and is fixedly connected to the rear end of one of the conveying rollers. A discharge hole is provided on the top of the side of the lifting box away from the holding box.

[0013] By adopting the above technical solution, the motor can drive the conveyor rollers fixedly connected to its output shaft to rotate, thereby controlling the conveyor belt to drive the multiple partition plates installed on it to rotate, which can lift and transport the recycled aggregate concrete raw materials to a high place and discharge them from the discharge hole.

[0014] Optionally, a guide plate is fixedly installed on the side of the lifting box away from the material container, and the guide plate is inclined.

[0028] This application utilizes a lifting and feeding mechanism to lift and transport the weighed recycled aggregate concrete raw materials in the holding bin to a high position and discharge them from the discharge hole before entering the mixing equipment.

[0029] This application utilizes the combined action of a rotating shaft, a material-pulling rod, a main pulley, a secondary pulley, and a belt to continuously move the recycled aggregate concrete raw materials in the holding box. This effectively prevents the recycled aggregate concrete raw materials from accumulating in the holding box and clogging the feeding hole, ensuring the continuity and stability of the entire raw material conveying process and avoiding production interruptions and equipment failures caused by blockages.

[0030] This application utilizes four casters to facilitate the movement of the weighing device as a whole, making it more convenient to use. By utilizing the combined action of hydraulic cylinder 2, positioning plate and anti-slip pad, the weighing device can be easily fixed to the ground, making it less prone to displacement during use.

[0031] This application optimizes the overall weight distribution of the weighing device by utilizing a counterweight base, making the weighing device more stable during use and reducing the risk of tipping or shaking due to unstable center of gravity or external interference.

[0039] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0040] This application discloses a raw material weighing device for recycled aggregate concrete, including a material container 1 and a weighing box 2 fixedly mounted on the top of the material container 1. The top and bottom of the weighing box 2 are open structures, with the bottom extending into the material container 1. A pad 3 is fixedly mounted on the inner wall of the bottom of the material container 1, and a hydraulic cylinder 4 is fixedly mounted on the top of the pad 3. A bearing plate 5 is fixedly mounted on the output shaft end of the hydraulic cylinder 4. The top of the bearing plate 5 extends into the weighing box 2 and a weighing sensor 6 is fixedly mounted thereon. A U-shaped receiving plate 7 is fixedly mounted on the top of the weighing sensor 6. Utilizing the telescopic feature of the hydraulic cylinder 4, the vertical movement of the bearing plate 5, the weighing sensor 6, and the U-shaped receiving plate 7 can be controlled. The weighing sensor 6 can accurately weigh and measure the recycled aggregate concrete raw material on the U-shaped receiving plate 7. It should be noted that, as... Figure 3 As shown, hydraulic cylinder 4 is in the extended state. The bottom inner wall of the U-shaped receiving plate 7 is an inclined surface structure that gradually slopes downward from the middle to both sides. When the U-shaped receiving plate 7 is moved down into the material box 1, it can ensure that the raw material of recycled aggregate concrete falls smoothly from the U-shaped receiving plate 7, and can prevent the raw material of recycled aggregate concrete from accumulating on the bottom inner wall of the U-shaped receiving plate 7. The front and rear outer walls of the U-shaped receiving plate 7 are in sliding sealing contact with the front and rear inner walls of the weighing box 2, respectively. The left and right outer walls of the U-shaped receiving plate 7 are in sliding sealing contact with the left and right inner walls of the weighing box 2, respectively. This can ensure that the raw material of recycled aggregate concrete enters the gap between the U-shaped receiving plate 7 and the weighing box 2. A feeding hole 8 is opened on one side wall of the material box 1. The feeding hole 8 is used to discharge the raw material of recycled aggregate concrete inside the material box 1.

[0041] The material container 1 is equipped with a lifting and feeding mechanism for lifting and conveying the weighed recycled aggregate concrete raw materials. The lifting and feeding mechanism includes a lifting box 9, conveying rollers 10, a conveyor belt 11, partition plates 12, and a motor 13. The lifting box 9 is fixedly installed on one side of the material container 1. A feed hole 14 is opened on the side of the lifting box 9 closest to the material container 1. The feed hole 14 is connected to the feeding hole 8, ensuring that the recycled aggregate concrete raw materials discharged from the feeding hole 8 enter the lifting box 9 through the feed hole 14. The number of conveying rollers 10 is set to multiple, and the multiple conveying rollers 10 are rotatably installed in the lifting box 9 and are evenly distributed vertically. The conveyor belt 11 is wound around the multiple conveying rollers 10. The number of partition plates 12 is set to multiple, and the multiple partition plates 12 are fixedly installed in the material container 9. The conveyor belt 11 is evenly distributed on its outer wall. The motor 13 is fixedly installed on the rear side wall of the lifting box 9. The output shaft of the motor 13 extends into the lifting box 9 and is fixedly connected to the rear end of one of the conveying rollers 10. The top of the side of the lifting box 9 away from the material box 1 has a discharge hole 15. The motor 13 can drive the conveying roller 10 fixedly connected to its output shaft to rotate. Then, under the joint action of multiple conveying rollers 10, the conveyor belt 11 can be controlled to drive the multiple partition plates 12 installed on it to rotate. This can lift and transport the recycled aggregate concrete raw material to a high place and discharge it from the discharge hole 15, which improves the efficiency of recycled aggregate concrete raw material transportation, reduces the workload and time cost of manual handling and transfer of raw materials, and improves the continuity of the production process.

[0042] In this embodiment, a guide plate 16 is fixedly installed on the side of the lifting box 9 away from the material box 1. The guide plate 16 is inclined so as to guide the recycled aggregate concrete raw material discharged from the discharge hole 15 to the mixing equipment.

[0043] In this embodiment, the bottom inner wall of the material holding box 1 is inclined, and the feeding hole 8, the inlet hole 14 and the discharge hole 15 are all inclined, which can ensure that the recycled aggregate concrete raw materials in the material holding box 1 can smoothly and completely enter the lifting box 9.

[0044] In this embodiment, a rotating shaft 17 is rotatably installed inside the material container 1. Multiple material-pulling rods 18 are fixedly installed on the rotating shaft 17. The multiple material-pulling rods 18 are evenly distributed. The front end of the conveying roller 10 located at the bottom extends to the outside of the lifting box 9 and is fixedly fitted with a main pulley 19. The front end of the rotating shaft 17 extends to the outside of the material container 1 and is fixedly fitted with a secondary pulley 20. The same belt 21 is wound around the main pulley 19 and the secondary pulley 20. By utilizing the transmission action of the main pulley 19, the secondary pulley 20 and the belt 21, the rotating shaft 17 and the conveying roller 10 can be controlled to rotate simultaneously. The rotating shaft 17 drives the multiple material-pulling rods 18 to rotate, which can continuously move the recycled aggregate concrete raw material in the material container 1. This effectively prevents the recycled aggregate concrete raw material from accumulating in the material container 1 and blocking the feeding hole 8, ensuring the continuity and stability of the entire raw material conveying process and avoiding production interruptions and equipment failures caused by blockages.

[0045] In this embodiment, casters 22 are rotatably installed at the four corners of the bottom of the material container 1 to facilitate the movement of the weighing device as a whole.

[0046] In this embodiment, a hydraulic cylinder 23 is fixedly installed at the bottom center of the material container 1. A positioning plate 24 is fixedly installed at the output shaft end of the hydraulic cylinder 23. An anti-slip pad 25 is fixedly installed at the bottom of the positioning plate 24, which makes it easy to fix the weighing device as a whole on the ground and prevents it from shifting during use.

[0047] In this embodiment, a counterweight 26 is fixedly installed on the side of the material container 1 away from the lifting box 9. The setting of the counterweight 26 optimizes the overall weight distribution of the weighing device, making the weighing device more stable during use and reducing the risk of tipping or shaking due to unstable center of gravity or external interference.

[0048] In this embodiment, it should be further explained that a controller is installed on the outer wall of the material container 1. The controller is equipped with a display screen and multiple control buttons. The weighing sensor 6, motor 13, hydraulic cylinder 4, and hydraulic cylinder 23 are all electrically connected to the controller. The weighing data value measured by the weighing sensor 6 can be displayed on the display screen for easy viewing by the staff. The multiple control buttons can be used to control the weighing sensor 6, motor 13, hydraulic cylinder 4, and hydraulic cylinder 23 to operate simultaneously. The wiring connection method and control method are mature technologies in this field and are fully disclosed in the description. Therefore, they will not be described in detail here.

[0049] With the above structure, the working principle of the raw material weighing device for recycled aggregate concrete provided in this application is as follows:

[0050] Push the weighing device to a suitable position in front of the mixing equipment used for mixing recycled aggregate concrete raw materials, so that the guide plate 16 is directly above the mixing equipment. Then control the extension of the hydraulic cylinder 23 to make the positioning plate 24 and the anti-slip pad 25 descend vertically. When the anti-slip pad 25 descends to the point of tightly contacting the ground, stop the operation of the hydraulic cylinder 23. At this time, the weighing device is stably fixed on the ground and will not shift during subsequent use.

[0051] Then, the weighing sensor 6 is activated, and one type of recycled aggregate concrete raw material is poured into the U-shaped receiving plate 7 inside the weighing box 2. At this time, the weighing sensor 6 can accurately weigh the recycled aggregate concrete raw material falling on the U-shaped receiving plate 7. When the required weight of recycled aggregate concrete raw material is weighed on the U-shaped receiving plate 7, the hydraulic cylinder 4 is controlled to retract and reset, which controls the bearing plate 5, the weighing sensor 6, and the U-shaped receiving plate 7 to move vertically downward. The bottom of the U-shaped receiving plate 7 will descend into the holding box 1. At this time, the weighed raw material on the U-shaped receiving plate 7... The recycled aggregate concrete raw materials will fall onto the bottom inner wall of the holding box 1. When all the recycled aggregate concrete raw materials on the U-shaped receiving plate 7 have fallen into the holding box 1, the hydraulic cylinder 4 is extended and operated, which controls the bearing plate 5, the weighing sensor 6 and the U-shaped receiving plate 7 to move vertically upward until the top of the U-shaped receiving plate 7 is about to be exposed outside the weighing box 2. Then the hydraulic cylinder 4 is stopped. Following the above operation steps, the other types of recycled aggregate concrete raw materials can be accurately weighed and sent into the holding box 1 in sequence, thus realizing the accurate weighing operation of recycled aggregate concrete raw materials.

[0052] During the weighing process of the recycled aggregate concrete raw materials, the recycled aggregate concrete raw materials falling into the material box 1 will slide into the lifting box 9 through the feeding hole 8 and the inlet hole 14 in sequence. The motor 13 is turned on and runs. The output shaft of the motor 13 drives the conveying roller 10, which is fixedly connected to its output shaft end, to rotate. This can control the conveyor belt 11 to drive the multiple partition plates 12 installed on it to rotate, so that the recycled aggregate concrete raw materials can be lifted and transported to a high place and discharged from the discharge hole 15. The recycled aggregate concrete raw materials discharged from the discharge hole 15 are guided by the guide plate 16 and fall into the mixing equipment, thus realizing the lifting and feeding operation.

[0053] During the process of lifting and conveying recycled aggregate concrete raw materials, the main pulley 19, the auxiliary pulley 20 and the belt 21 can be used to drive the rotating shaft 17 and the conveying roller 10 to rotate simultaneously. The rotating shaft 17 drives multiple material-pulling rods 18 to rotate, which can continuously move the recycled aggregate concrete raw materials in the holding box 1. This effectively prevents the recycled aggregate concrete raw materials from accumulating in the holding box 1 and blocking the feeding hole 8, so that the recycled aggregate concrete raw materials in the holding box 1 can enter the lifting box 9 more smoothly and thoroughly. This ensures the continuity and stability of the entire raw material conveying process and avoids production interruption and equipment failure caused by blockage.

[0054] After the work is completed, turn off the weighing sensor 6 and the motor 13, and then control the hydraulic cylinder 23 to retract and reset. This will control the positioning plate 24 and the anti-slip pad 25 to move vertically upward back to their original positions, and then the entire weighing device can be pushed to the desired position.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
