[0002] In modern construction projects, concrete is a vital building material. With the increasing complexity of building structures and the continuous improvement of construction quality requirements, the quality control of commercial concrete has become more stringent. Different building parts, such as the load-bearing and non-load-bearing structures of high-rise buildings and the different parts of bridges, have different requirements for the size and distribution of concrete particles, so concrete screening devices are needed to screen them.
[0003] Traditional equipment usually performs simple coarse screening, which makes it difficult to accurately distinguish particles of various particle size ranges. Due to the inaccurate screening process, the particle size of the commercial concrete produced is difficult to meet the complex and diverse construction needs. Utility Model Content
[0004] The purpose of the utility model is to provide a screening device for commercial concrete production, which solves the problem that traditional equipment usually performs simple coarse screening and is difficult to accurately distinguish particles of various different particle size ranges. Due to the inaccurate screening process, the particle size of the commercial concrete produced is difficult to meet the complex and diverse construction needs.
[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0006] The utility model is a screening device for commercial concrete production, comprising a machine base, wherein a screening mechanism is arranged inside the machine base, a dust suction mechanism is fixedly mounted on the upper surface of the machine base, and a dust suction end of the dust suction mechanism is arranged at the upper end of the screening mechanism.
[0007] Furthermore, the screening mechanism includes a screening box, and the internal sliding connection of the screening box is provided with several limit slide rods, and the limit slide rods are respectively distributed at the four corners of the screening box, and one end of the limit slide rod is fixedly connected to the outer surface of the machine base, and a spring is provided on the outer side of the limit slide rod, and one end of the spring is fixedly connected to the screening box, and the other end of the spring is fixedly connected to the outer surface of the machine base.
[0008] Furthermore, a coarse filter plate, a fine filter plate and a material guide plate are fixedly installed inside the screening box, the fine filter plate is arranged below the coarse filter plate, and the material guide plate is arranged below the fine filter plate. The coarse filter plate, the fine filter plate and the material guide plate are all arranged at an angle, and a discharge port is opened on one side of the screening box. The number of the discharge ports is fixed at three, and the three discharge ports are respectively opened at one end of the coarse filter plate, the fine filter plate and the material guide plate.
[0009] Furthermore, a motor is fixedly mounted on the outer surface of the screening box, and an eccentric block is fixedly mounted on the output end of the motor.
[0010] Furthermore, a protective shell is fixedly installed on the outer surface of the screening box, and the protective shell covers the motor and the eccentric block.
[0011] Furthermore, the dust suction mechanism includes a suction fan, which is fixedly mounted on the upper surface of the machine base, a connecting pipe is fixedly mounted on the output end of the suction fan, an input pipe is fixedly mounted on the input end of the suction fan, a bracket is fixedly mounted on the upper surface of the machine base, an expansion head is fixedly mounted on one side of the bracket, the expansion head is connected to the input pipe, and the expansion head is arranged at the upper end of the screening mechanism.
[0012] The utility model has the following beneficial effects:
[0013] (1) The utility model is started by the motor, and the eccentric block at the output end begins to rotate. Due to the rotation of the eccentric block, a periodic centrifugal force is generated. This centrifugal force acts on the screening box, causing the screening box to reciprocate along the limit slide. The limit slide plays a role in limiting and guiding the screening box, ensuring that the screening box can only move in a specific direction. The spring connects the screening box and the machine base. When the screening box moves, the spring will expand and contract. The elastic force of the spring and the centrifugal force generated by the motor work together to maintain the stable reciprocating motion of the screening box. Inside the screening box, the coarse filter plate, fine filter plate and guide plate are arranged at an angle. When the commercial concrete enters the screening box, under the reciprocating motion of the screening box, the larger particles of material will be intercepted by the coarse filter plate and discharged from the corresponding discharge port along the inclined surface of the coarse filter plate. The smaller particles of material pass through the coarse filter plate and fall onto the fine filter plate. The fine filter plate screens the material again, and the smaller particles of material pass through the fine filter plate and fall onto the guide plate. Finally, they are discharged from their respective discharge ports, thereby realizing the graded screening of the commercial concrete, achieving a more fine graded screening of the commercial concrete, improving the accuracy and comprehensiveness of the screening, and meeting the production requirements of different particle size requirements.
[0014] (2) The utility model starts the dust collection mechanism while the screening mechanism is working, and the suction fan starts to suck air through the input pipe. Since the expansion head is connected to the input pipe and is arranged at the upper end of the screening mechanism, the expansion head can increase the range of dust collection. The dust generated during the screening process is sucked in by the suction force generated by the suction fan, passes through the input pipe and the suction fan, and is finally transported to the external dust removal box connected to the connecting pipe through the connecting pipe, which effectively reduces the diffusion of dust in the working environment, improves the working environment, is beneficial to the health of the operators, and also meets the requirements of environmental protection.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figures 1-4 As shown, the utility model is a screening device for commercial concrete production, comprising a base 1, a screening mechanism 2 is provided inside the base 1, a dust collection mechanism 4 is fixedly mounted on the upper surface of the base 1, and a dust collection end of the dust collection mechanism 4 is provided at the upper end of the screening mechanism 2;
[0025] The screening mechanism 2 includes a screening box 201, and a plurality of limit slide bars 202 are slidably connected to the interior of the screening box 201. The limit slide bars 202 are respectively distributed at the four corners of the screening box 201. One end of the limit slide bar 202 is fixedly connected to the outer surface of the base 1. A spring 203 is sleeved on the outer side of the limit slide bar 202. One end of the spring 203 is fixedly connected to the screening box 201, and the other end of the spring 203 is fixedly connected to the outer surface of the base 1.
[0026] A coarse filter plate 204, a fine filter plate 205 and a guide plate 206 are fixedly installed inside the screening box 201. The fine filter plate 205 is arranged below the coarse filter plate 204, and the guide plate 206 is arranged below the fine filter plate 205. The coarse filter plate 204, the fine filter plate 205 and the guide plate 206 are all arranged at an angle. A discharge port 207 is opened on one side of the screening box 201. The number of the discharge ports 207 is fixed at three, and the three discharge ports 207 are respectively opened at one end of the coarse filter plate 204, the fine filter plate 205 and the guide plate 206;
[0027] The outer surface of the screening box 201 is fixedly mounted with a motor 208, and the output end of the motor 208 is fixedly mounted with an eccentric block 209. The motor 208 is provided with a mounting hole, and the screws installed in the mounting hole are fixed to the outer surface of the screening box 201. The motor 208 and the eccentric block 209 constitute a vibration motor. When the output shaft of the motor 208 rotates, the eccentric block 209 is driven to rotate and generate vibration. When the vibration motor is working, it acts on the screening box 201 and drives the screening box 201 to vibrate up and down.
[0028] A protective shell 3 is fixedly mounted on the outer surface of the screening box 201, and the protective shell 3 covers the motor 208 and the eccentric block 209;
[0029] The motor 208 is started, and the eccentric block 209 at its output end begins to rotate. Due to the rotation of the eccentric block 209, a periodic centrifugal force is generated. This centrifugal force acts on the screening box 201, causing the screening box 201 to reciprocate along the limit slide 202. The limit slide 202 limits and guides the screening box 201, ensuring that the screening box 201 can only move in a specific direction. The spring 203 connects the screening box 201 and the base 1. When the screening box 201 moves, the spring 203 will expand and contract. The elastic force of the spring 203 and the centrifugal force generated by the motor 208 work together to maintain the stable reciprocating motion of the screening box 201. Inside the screening box 201, the coarse filter plate 204, the fine filter plate 205 and the guide plate The material plate 206 is arranged at an angle. When the commercial concrete enters the screening box 201, the reciprocating motion of the screening box 201 intercepts the larger particles of material by the coarse filter plate 204 and is discharged from the corresponding discharge port 207 along the inclined surface of the coarse filter plate 204. The smaller particles of material pass through the coarse filter plate 204 and fall onto the fine filter plate 205. The fine filter plate 205 screens the material again. The smaller particles of material pass through the fine filter plate 205 and fall onto the guide plate 206. Finally, they are discharged from their respective discharge ports 207, thereby realizing graded screening of the commercial concrete, achieving relatively fine graded screening of the commercial concrete, improving the accuracy and comprehensiveness of the screening, and meeting the production requirements of different particle size requirements.
[0030] The dust collection mechanism 4 includes a suction fan 401, which is fixedly mounted on the upper surface of the machine base 1. A connecting pipe 402 is fixedly mounted on the output end of the suction fan 401, and an input pipe 403 is fixedly mounted on the input end of the suction fan 401. A bracket 404 is fixedly mounted on the upper surface of the machine base 1, and an expansion head 405 is fixedly mounted on one side of the bracket 404. The expansion head 405 is connected to the input pipe 403 and is arranged at the upper end of the screening mechanism 2.
[0031] While the screening mechanism 2 is working, the dust collection mechanism 4 is started, the suction fan 401 is started, and air is sucked through the input pipe 403. Since the expansion head 405 is connected to the input pipe 403 and is arranged at the upper end of the screening mechanism 2, the expansion head 405 can increase the range of dust collection. The dust generated during the screening process is sucked in by the suction force generated by the suction fan 401, passes through the input pipe 403 and the suction fan 401, and is finally transported to the external dust removal box connected to the connecting pipe 402 through the connecting pipe 402, which effectively reduces the spread of dust in the working environment, improves the working environment, is beneficial to the health of the operators, and also meets environmental protection requirements.
[0032] When in use, first the motor 208 is started, and the eccentric block 209 at its output end begins to rotate. Due to the rotation of the eccentric block 209, a periodic centrifugal force is generated. This centrifugal force acts on the screening box 201, causing the screening box 201 to reciprocate along the limit slide 202. The limit slide 202 limits and guides the screening box 201, ensuring that the screening box 201 can only move in a specific direction. The spring 203 connects the screening box 201 and the base 1. When the screening box 201 moves, the spring 203 will expand and contract. The elastic force of the spring 203 and the centrifugal force generated by the motor 208 work together to maintain the stable reciprocating motion of the screening box 201. Inside the screening box 201, the coarse filter plate 204 and the fine filter plate 205 The material guide plate 206 is arranged at an angle. When the commercial concrete enters the screening box 201, the reciprocating motion of the screening box 201 will intercept the larger particles of material by the coarse filter plate 204 and discharge them from the corresponding discharge port 207 along the inclined surface of the coarse filter plate 204. The smaller particles of material pass through the coarse filter plate 204 and fall onto the fine filter plate 205. The fine filter plate 205 screens the material again. The smaller particles of material pass through the fine filter plate 205 and fall onto the guide plate 206. Finally, they are discharged from their respective discharge ports 207, thereby realizing graded screening of the commercial concrete, achieving relatively fine graded screening of the commercial concrete, improving the accuracy and comprehensiveness of screening, and meeting the production requirements of different particle size requirements.
[0033] While the screening mechanism 2 is working, the dust collection mechanism 4 is started, the suction fan 401 is started, and air is sucked through the input pipe 403. Since the expansion head 405 is connected to the input pipe 403 and is arranged at the upper end of the screening mechanism 2, the expansion head 405 can increase the range of dust collection. The dust generated during the screening process is sucked in by the suction force generated by the suction fan 401, passes through the input pipe 403 and the suction fan 401, and is finally transported to the external dust removal box connected to the connecting pipe 402 through the connecting pipe 402, which effectively reduces the spread of dust in the working environment, improves the working environment, is beneficial to the health of the operators, and also meets environmental protection requirements.
