Abstract

Technical Field

[0002] Screening machine is a vibrating screening machine that uses the relative movement between bulk materials and the screen surface to make some particles pass through the screen holes, and classifies materials such as sand, gravel, and crushed stone into different grades according to particle size. The screening process of the screening machine is generally continuous. After the screening raw materials are fed to the screening machine, the materials smaller than the size of the screen holes pass through the screen holes, which are called undersize products; the materials larger than the size of the screen holes are continuously discharged from the screen surface, which are called oversize products.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example 1
[0022] like Figure 1 As shown:
[0023] A sediment screening device comprises two groups of support frames 1, a driving mechanism 2 installed between the two groups of support frames 1, and a screening drum 3 installed on the driving mechanism 2.
[0024] In this implementation scheme: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "at present, when the environment in which the sediment is located is close to the groundwater level, the moisture in the soil may move upward through capillary action, causing the soil inside the sediment to become moist. The moist soil causes blockage of the screen of the sediment screening device mainly because of its high moisture content and easy adhesion. When the moist soil passes through the screen, due to the high moisture content, the soil particles are easy to stick together and clumping. Such agglomerated materials are difficult to pass through the pores of the screen, thereby causing blockage of the screen and affecting the screening effect." In terms of combined use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, an anti-blocking component 4 and a moving component 5 are added to the application document, and the electrical equipment involved in this product are all powered by an external power supply.
[0025] It should be noted that the driving mechanism 2 includes a motor, a driving rod, a driving wheel and a limiting ring. The motor drives the driving rod to rotate, the driving rod drives the driving wheel to rotate, the driving wheel rotates on the limiting ring, and then drives the screening drum 3 to rotate.
[0026] More specifically:
[0027] like Figure 1-Figure 4 As shown:
[0028] An anti-clogging component 4 is installed on the screening cylinder 3, and the anti-clogging component 4 includes a U-shaped bracket 401 fixed on the surface of the support frame 1, a connecting bracket 402 arranged between two groups of U-shaped brackets 401, and an exhaust pipe 403 fixed on the lower surface of the connecting bracket 402. The surface of the exhaust pipe 403 is provided with multiple groups of equidistantly arranged air nozzles, and an air pump 404 is fixedly installed on the surface of one group of U-shaped brackets 401 through a supporting plate, a connecting hose 405 is fixed to the output end of the air pump 404, and a connecting pipe is fixed to the other end of the connecting hose 405, a material receiving cover 406 is fixed to the surface of the connecting bracket 402, and a conveying shell 407 is fixed to the lower surface of the material receiving cover 406, one end of the connecting pipe passes through the connecting bracket 402, and is fixedly connected to the exhaust pipe 403, and is communicated with the exhaust pipe 403, the material receiving cover 406 is located inside the screening cylinder 3, and the conveying shell 407 is designed with an inclined structure as a whole.
[0029] In the present embodiment, when the sediment screening device is in use, when the sediment is transported to the interior of the screening drum 3, the screening drum 3 is driven to rotate by the driving mechanism 2, and the sediment inside the screening drum 3 is screened. In this process, by starting the air pump 404, the generated gas is transported to the connecting hose 405 and discharged to the interior of the exhaust pipe 403 through the connecting pipe. The gas inside the exhaust pipe 403 is discharged through the air nozzle. The impact force of the discharged gas blows away the mud clumps remaining in the sieve holes of the screening drum 3, and the mud clumps fall into the inside of the receiving cover 406, and fall onto the conveying shell 407 through the receiving cover 406. Since the conveying shell 407 is designed with an inclined structure, the mud clumps are discharged through the conveying shell 407. As the screening drum 3 continues to roll, the sieve holes of the screening drum 3 are continuously cleaned. The high-pressure airflow can effectively remove the mud clumps in the sieve holes on the screening drum 3, thereby improving the screening efficiency, thereby effectively preventing the sieve holes from being blocked by mud clumps, and thus improving the use effect of the device.
[0030] Going further;
[0031] In an optional embodiment, the discharge port of the material receiving cover 406 is provided with a blocking fan-shaped rod 409, which is rotatably connected to the material receiving cover 406 through a bearing, and a servo motor 408 is fixedly installed on one side of the connecting bracket 402 by bolts, and the output end of the servo motor 408 passes through the connecting bracket 402 and is fixedly connected to one end of the blocking fan-shaped rod 409.
[0032] In the present embodiment: as the mud balls continuously fall into the inside of the receiving cover 406, the servo motor 408 is started at the same time, thereby driving the blocking fan-shaped rod 409 to rotate, so that the mud balls are discharged along the blocking fan-shaped rod 409 to the inside of the conveying shell 407, so that the discharge port of the receiving cover 406 can be blocked at all times, avoiding the mud balls inside the receiving cover 406 from splashing everywhere due to the large airflow discharged into the inside of the receiving cover 406, and avoiding the blockage of the discharge port, thereby further improving the use effect of the device.
[0033] Further,
[0034] In an optional embodiment, a moving component 5 is installed on the anti-blocking component 4, and the moving component 5 includes a gear 1 501 fixed to the output end of the servo motor 408, a gear 2 502 meshingly connected to one side of the gear 1 501, and a connecting hose 2 504 fixed on the surface of the connecting hose 1 405, a fixed tube 503 is fixed to one end of the connecting hose 2 504, the fixed tube 503 is fixedly connected to the U-shaped bracket 401, and passes through the U-shaped bracket 401, and corresponds to the gear 2 502, a plurality of groups of equidistantly arranged through holes 507 are provided on the surface of the gear 2 502, the connecting bracket 402 is slidably connected to the two groups of U-shaped brackets 401 through a slide rail, a square plate 505 is fixed to one end of the connecting bracket 402, a spring 506 is fixed between the square plate 505 and the U-shaped bracket 401, the connecting hose 2 504 is connected to the connecting hose 1 405, a guide rod is fixed to the inside of the gear 2 502 by a screw, and one end of the guide rod is rotatably connected to the connecting bracket 402 through a bearing.
[0035] In this embodiment, the servo motor 408 drives the gear 1 501 to rotate, and the gear 1 501 drives the gear 2 502 to rotate. During this process, part of the gas from the connecting hose 1 405 is discharged to the inside of the connecting hose 2 504, and then discharged to the fixed pipe 503 through the connecting hose 2 504. When the airflow impact force generated by the fixed pipe 503 impacts the gear 2 502, the connecting bracket 402 is driven by the gear 2 502 to move horizontally on the U-shaped bracket 401, and the connecting bracket 402 drives the exhaust pipe 403 moves synchronously, and with the movement of the connecting bracket 402, the spring 506 is compressed through the square plate 505. When the fixed pipe 503 corresponds to the through hole 507, the impact on the gear 2 502 is released. At this time, the spring 506 rebounds and drives the connecting bracket 402 to reset. Through this operation, the exhaust pipe 403 can be driven to move back and forth, so that the airflow blows more evenly on the sieve hole of the screening cylinder 3, improves the cleaning effect of the screening cylinder 3, avoids blockage, and further improves the use effect of the device.
[0036] The working principle and use process of the utility model are as follows: when the silt screening device is in use, when the silt is transported to the inside of the screening cylinder 3, the screening cylinder 3 is then driven to rotate by the driving mechanism 2, and the silt inside the screening cylinder 3 is screened. In this process, the gas generated by starting the air pump 404 is transported to the connecting hose 405, and is discharged to the inside of the exhaust pipe 403 through the connecting pipe. The gas inside the exhaust pipe 403 is discharged through the air nozzle. The impact force of the discharged gas blows off the mud clumps remaining in the sieve holes of the screening cylinder 3, and the mud clumps fall into the inside of the receiving cover 406, and fall onto the conveying shell 407 through the receiving cover 406. The conveying shell 407 is designed with an inclined structure, so that the mud is discharged through the conveying shell 407. As the screening drum 3 continues to roll, the screen holes of the screening drum 3 are continuously cleaned. The high-pressure airflow can effectively remove the mud in the screen holes on the screening drum 3, improve the screening efficiency, and effectively avoid the mud from blocking the screen holes, thereby improving the use effect of the device. As the mud continues to fall into the inside of the receiving cover 406, the servo motor 408 is started at the same time, which drives the blocking fan-shaped rod 409 to rotate, so that the mud is discharged along the blocking fan-shaped rod 409 to the inside of the conveying shell 407, so that the discharge port of the receiving cover 406 can be blocked at all times. In this state, when a large airflow is discharged to the inside of the receiving cover 406, the mud balls inside the receiving cover 406 can be effectively prevented from splashing everywhere due to the airflow, and the blockage of the discharge port can be avoided, so as to further improve the use effect of the device. At the same time, the servo motor 408 drives the gear 1 501 to rotate, and the gear 1 501 drives the gear 2 502 to rotate. In this process, part of the gas from the connecting hose 1 405 is discharged to the inside of the connecting hose 2 504, and is discharged to the fixed pipe 503 through the connecting hose 2 504. When the airflow impact force generated by the fixed pipe 503 impacts the gear 2 502, the gear 2 502 is driven by the gear 2 502. The connecting bracket 402 is driven to move horizontally on the U-shaped bracket 401, and the connecting bracket 402 drives the exhaust pipe 403 to move synchronously. As the connecting bracket 402 moves, the spring 506 is compressed through the square plate 505. When the fixed pipe 503 corresponds to the through hole 507, the impact on the gear 2 502 is released. At this time, the spring 506 rebounds and drives the connecting bracket 402 to reset. Through this operation, the exhaust pipe 403 can be driven to move back and forth, so that the airflow blows more evenly on the sieve hole of the screening cylinder 3, thereby improving the cleaning effect of the screening cylinder 3, avoiding blockage, and further improving the use effect of the device.
