Description

Technical Field

[0001] The utility model relates to the technical field of concrete material selection, in particular to a concrete material selection device. Background Art

[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates, and water with admixtures and additives in a certain proportion. The cement concrete obtained by mixing is also called ordinary concrete. It is widely used in civil engineering.

[0003] In the prior art, such as Chinese Patent No. CN212168086U, a concrete material selection device relates to the field of concrete material technology. The utility model includes a selection tank, which includes a feed hopper, a screening hopper, and a discharge pipe. A circular tube and a partition are fixed to the inner top of the selection tank. The bottom end of the partition rotates with a row of baffles. A motor is fixed to the upper surface of the selection tank. The motor rotor passes through the top shell of the selection tank and is fixed to a rotating rod. The bottom end of the rotating rod is fixed with blades that can cooperate with the baffles. A vibration motor is fixed to the circumferential side of the selection tank. One end of the vibration motor's output shaft passes through the selection tank and is fixed to a screen plate. One side of the screen plate has a fan-shaped notch that can cooperate with the screening hopper. The utility model uses a screen plate controlled by a vibration motor to perform preliminary screening of the stone. The rotating rod controlled by the motor drives the blades to rotate, discharging the stone remaining after screening, thereby achieving stone selection and reducing the time consumed by the selection process.

[0004] Although the above scheme has the advantages as mentioned above, the disadvantage of the above scheme is that after the traditional concrete material selection device is completed, a large amount of aggregate needs to be discharged from the discharge port, which usually causes blockage. Manual unblocking is extremely troublesome, time-consuming and labor-intensive, and requires the device to be disassembled for unblocking. The discharge port cannot be treated to prevent blockage, which reduces the overall selection efficiency of the concrete material selection device. When the aggregate is poured into the feed port, a large amount of dust will be generated, which greatly affects the workers' vision. The dust cannot be reduced, which greatly affects the environment and reduces the environmental protection function of the concrete material selection device. Utility Model Content

[0021] Compared with the prior art, the advantages and positive effects of the present utility model are:

[0022] 1. In this utility model, first, the aggregate to be screened for concrete is poured into the box from the feeding hopper. Then, the external power supply of the vibrator is turned on, and the vibrator is started by the controller. The vibrator starts to vibrate continuously and drives the entire filter screen plate to vibrate. At this time, the spring located below the filter screen plate provides a good vibration amplitude for it, and the telescopic column limits the spring to prevent the spring from bouncing in a deviated direction. At the same time, the qualified aggregate falls from the surface of the filter screen plate into the discharge plate below the box. When a large amount of aggregate blocks the discharge pipe, the staff turns on the external power supply of the first motor and starts the first motor by the controller. The output end of the first motor drives the first swing rod to perform a circular motion. As the first swing rod performs a circular motion, the second swing rod starts to swing left and right along with the first swing rod. Through the swing of the first swing rod, the pull rod in the hollow column starts to be repeatedly twitched. The discharge pipe is repeatedly knocked by the pull rod to generate vibration, creating small spaces in the blocked aggregate in the discharge pipe, and then the aggregate falls out, thus completing the anti-blocking treatment of the discharge pipe, preventing blockage when a large amount of aggregate is discharged, eliminating the need for manual dredging, being extremely simple, time-saving and labor-saving, and not requiring disassembly of the device for dredging, facilitating the anti-blocking treatment of the discharge port, and improving the overall material selection efficiency of the concrete material selection device.

[0023] 2. In this utility model, when the aggregate is screened on the surface of the filter screen plate, a large amount of dust will be generated due to high-frequency vibration. To facilitate dust reduction treatment, the staff turns on the second motor and starts the second motor by the controller. The second motor starts to drive the reciprocating threaded rod to rotate forward. As the reciprocating threaded rod continues to rotate forward, the slider located on the surface of the reciprocating threaded rod starts to perform a reciprocating motion. At this time, the limiting column limits the slider to prevent the slider from idling. Through the continuous reciprocating motion of the slider, the long rack also moves accordingly. As the long rack moves, it gradually drives the circular gear to perform a reciprocating rotational motion. The circular gear drives the cylinder to rotate back and forth. At this time, the multi-nozzle head also swings back and forth along with the cylinder. At the same time, the staff turns on the external power supply of the liquid pump and starts the liquid pump by the controller. The liquid pump starts to pump water from the water tank and transfer it to the multi-nozzle head, and opens the valve of the multi-nozzle head. The multi-nozzle head starts to sprinkle water in a reciprocating motion. The water tank has been filled with water before, and the evenly sprayed water is used to reduce the dust, thus achieving the dust reduction treatment of the dust, ensuring environmental safety, and improving the environmental protection function of the concrete material selection device.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Example 1, please refer to Figures 1 - 4, the utility model provides a technical solution: a concrete material selection device, including a box body 1, a feeding hopper 102 is fixedly connected to the top of the box body 1, a blanking plate 104 is fixedly connected to the bottom edge of the box body 1, a discharge pipe 105 is fixedly embedded inside the blanking plate 104, a plurality of support legs 101 are fixedly connected to the outer surface of the box body 1, a first motor 106 is fixedly installed near the edge at the bottom of the blanking plate 104, the output end of the first motor 106 is fixedly connected to a first swing rod 107, one side of the outer surface of the first swing rod 107 is movably connected to a second swing rod 108, a fixing plate 111 is fixedly connected to the bottom of the blanking plate 104 near the center, a hollow column 110 is fixedly embedded inside the fixing plate 111, a pull rod 109 is movably embedded inside the hollow column 110, and both sides of the inner wall of the pull rod 109 are movably connected to both sides of the outer surface of the second swing rod 108. Both sides of the inner wall of the box body 1 are fixedly connected with adding blocks 214. Two springs 212 are fixedly connected to the top of the adding blocks 214 near the edge. Two telescopic columns 213 are fixedly connected to the top of both adding blocks 214. The top ends of the two springs 212 are fixedly connected to a filter screen plate 103. The bottom of the filter screen plate 103 is fixedly connected to the top ends of the telescopic columns 213. A vibrator 112 is fixedly installed at the center of the top of the filter screen plate 103.

[0033] In this embodiment, first, the aggregates to be screened for concrete are poured into the box body 1 from the feeding hopper 102. Then, the external power supply of the vibrator 112 is turned on, and the vibrator 112 is started by using the controller. The vibrator 112 starts to vibrate continuously and drives the entire filter screen plate 103 to vibrate. At this time, the spring 212 located below the filter screen plate 103 provides a good vibration amplitude for it. The telescopic column 213 limits the spring 212 to prevent the spring 212 from bouncing in a deviated direction. At the same time, the qualified aggregates fall from the surface of the filter screen plate 103 into the blanking plate 104 below the box body 1. When a large amount of aggregates are blocked in the discharge pipe 105, the staff turns on the external power supply of the first motor 106 and starts the first motor 106 by using the controller. The output end of the first motor 106 drives the first swing rod 107 to perform circular motion. As the first swing rod 107 performs circular motion, the second swing rod 108 starts to swing left and right along with the first swing rod 107. Through the swing of the first swing rod 107, the pull rod 109 located in the hollow column 110 starts to be repeatedly pulled. The discharge pipe 105 is repeatedly knocked by the pull rod 109 to generate vibration, so that the blocked aggregates in the discharge pipe 105 generate small spaces and then fall out, thereby completing the anti-blocking treatment of the discharge pipe 105, so as to prevent blockage when a large amount of aggregates are discharged, without the need to use manual dredging methods for dredging, which is extremely simple, time-saving and labor-saving, without the need to disassemble the device for dredging, facilitating the anti-blocking treatment of the blanking port, and improving the overall material selection efficiency of the concrete material selection device.

[0034] Example 2, asFigures 1 - 4 As shown in the figure, a cross plate 2 is fixedly connected to one side of the outer surface of the box body 1. A water tank 207 is fixedly installed near the edge of the top of the cross plate 2. A liquid pump 211 is fixedly installed on one side of the outer surface of the water tank 207. The input end of the liquid pump 211 is fixedly embedded inside the water tank 207. A circular gear 208 is movably connected near the center of the top of the cross plate 2. A cylinder 209 is fixedly connected to the center of the top of the circular gear 208. A multi-nozzle head 210 is fixedly connected to the outer surface of the cylinder 209. The output end of the liquid pump 211 is connected to the inside of the multi-nozzle head 210 through a hose. Two connecting plates 203 are fixedly connected to the top of the cross plate 2 near the edge. A reciprocating threaded rod 201 is movably connected to the inner sides of the outer surfaces of the two connecting plates 203. A limiting column 202 is fixedly connected to the inner sides of the outer surfaces of the two connecting plates 203. A second motor 204 is fixedly installed on one side of one of the connecting plates 203. The output end of the second motor 204 is fixedly connected to one end of the reciprocating threaded rod 201. A slider 205 is threadedly connected to the outer surface of the reciprocating threaded rod 201. A long rack 206 is fixedly connected to one side of the outer surface of the slider 205. The inner part of the slider 205 is movably sleeved on the outer surface of the limiting column 202. The outer surface of the long rack 206 meshes with the outer surface of the circular gear 208.

[0035] In this embodiment, when screening the aggregate on the surface of the filter mesh plate 103, a large amount of dust will be generated by the aggregate due to high-frequency vibration. For the convenience of dust reduction treatment, the staff turns on the second motor 204 and uses the controller to start the second motor 204. The second motor 204 starts to drive the reciprocating threaded rod 201 to rotate forward. As the reciprocating threaded rod 201 continues to rotate forward, the slider 205 located on the surface of the reciprocating threaded rod 201 starts to perform reciprocating motion. At this time, the limiting column 202 limits the slider 205 to prevent the slider 205 from idling. Through the continuous reciprocating motion of the slider 205, the long rack 206 also moves accordingly. As the long rack 206 moves, it gradually drives the circular gear 208 to perform reciprocating rotational motion. The circular gear 208 drives the cylinder 209 to rotate back and forth. At this time, the multi-nozzle head 210 also swings back and forth along with the cylinder 209. At the same time, the staff turns on the external power supply of the liquid pump 211 and uses the controller to start the liquid pump 211. The liquid pump 211 starts to pump water from the water tank 207 and transports it to the multi-nozzle head 210, and opens the valve of the multi-nozzle head 210. The multi-nozzle head 210 starts to perform sprinkling operations while swinging back and forth. The water tank 207 has been filled with water before. The evenly sprayed water is used to perform dust reduction treatment on the dust, so as to achieve dust reduction treatment on the dust, ensure environmental safety, and improve the environmental protection function of the concrete material selection device.

[0036] Working principle: When in use, first pour the aggregate to be screened for concrete into the box body 1 from the feeding hopper 102, and then turn on the external power supply of the vibrator 112. Use the controller to start the vibrator 112, and the vibrator 112 starts to vibrate continuously and drives the entire filter screen plate 103 to vibrate. At this time, the spring 212 located below the filter screen plate 103 provides a good vibration amplitude for it, and the telescopic column 213 limits the spring 212 to prevent the spring 212 from bouncing in a deviated direction. At the same time, the qualified aggregate falls from the surface of the filter screen plate 103 into the blanking plate 104 below the box body 1. When a large amount of aggregate blocks the discharge pipe 105, the staff turns on the external power supply of the first motor 106 and uses the controller to start the first motor 106. The output end of the first motor 106 drives the swing rod 107 to perform circular motion. As the swing rod 107 performs circular motion, the swing rod 108 starts to swing left and right along with the swing rod 107. Through the swing of the swing rod 107, the draw rod 109 located in the hollow column 110 starts to be repeatedly pulled. The draw rod 109 repeatedly knocks on the discharge pipe 105 and generates vibration, creating small spaces for the aggregate blocking the discharge pipe 105, and then it falls out, thus completing the anti-blocking treatment of the discharge pipe 105, preventing blockage when a large amount of aggregate is discharged, eliminating the need for manual dredging, being extremely simple, time-saving and labor-saving, and there is no need to disassemble the device for dredging, facilitating the anti-blocking treatment of the blanking port, improving the overall material selection efficiency of the concrete material selection device. And when the aggregate is screened on the surface of the filter screen plate 103, due to high-frequency vibration, a large amount of dust will be generated by the aggregate. For the convenience of dust reduction treatment, the staff turns on the second motor 204 and uses the controller to start the second motor 204. The second motor 204 starts to drive the reciprocating threaded rod 201 to rotate forward. As the reciprocating threaded rod 201 continuously rotates forward, the slider 205 located on the surface of the reciprocating threaded rod 201 starts to perform reciprocating motion. At this time, the limit post 202 limits the slider 205 to prevent the slider 205 from idling. Through the continuous reciprocating motion of the slider 205, the long rack 206 also moves accordingly. As the long rack 206 moves, it gradually drives the circular gear 208 to perform reciprocating rotational motion. The circular gear 208 drives the cylinder 209 to rotate back and forth. At this time, the multi-nozzle head 210 also swings back and forth along with the cylinder 209. At the same time, the staff turns on the external power supply of the liquid pump 211 and uses the controller to start the liquid pump 211. The liquid pump 211 starts to pump water from the water tank 207 and transmit it to the multi-nozzle head 210, and opens the valve of the multi-nozzle head 210. The multi-nozzle head 210 starts to sprinkle water in a reciprocating swing. The water tank 207 has been filled with water before. The evenly sprayed water is used for dust reduction treatment of the dust, thus achieving dust reduction treatment of the dust, ensuring environmental safety, and improving the environmental protection function of the concrete material selection device.
