Description

Technical Field

[0001] The present application relates to the technical field of vibrating screens, and in particular to an anti-blocking vibrating screen. Background Art

[0002] The vibrating screen works by using the reciprocating vibration generated by the vibrator. The upper rotating weight of the vibrator makes the screen surface produce a plane gyratory vibration, while the lower rotating weight makes the screen surface produce a conical gyratory vibration. The combined effect of the two makes the screen surface produce a compound gyratory vibration.

[0003] The main components of the vibrating screen are a box body, a vibrating motor, and a vibration-damping spring. A plurality of layers of screens are arranged in the box body, and the aperture of the screens decreases from top to bottom. Materials with particles smaller than the corresponding aperture of the screen pass through the upper screen and fall into the lower layer, while materials with particles larger than the corresponding aperture of the screen are blocked on the screen. However, when in use, sometimes a large amount of material is put in, and the screen cannot quickly transfer the upper material to the screen surface for screening, while the remaining materials in the lower layer are mostly larger particles, which block the screen holes. It is necessary to wait for the larger particles in the lower layer to be transferred to the discharge port to free the screen holes for screening and filtration, resulting in low screening efficiency. The Chinese patent (Announcement No.: CN208824960U) discloses an anti-blocking vibrating screen, which can speed up the screening and filtration efficiency of the vibrating screen.

[0004] In the above documents, when the material is turned over by a scraper, the scraper is in an arc shape. When turning over, the scraper tends to push the material to the middle of the inner cavity of the screen box, making it difficult for the scraper to push the screened material out of the screen box, resulting in the screened material being easily accumulated in the screen and the screen box, and the screened material will clog the screen holes of the screen, thereby reducing the screening efficiency. In addition, when adding materials to the screen box in the above documents, the staff is required to frequently lift and lower the box cover, which makes adding materials more cumbersome.

[0013] Furthermore, two sliding grooves are provided on the front and rear walls on the inner side of the connecting bin, and the concave block is slidably connected to the inner side of the sliding grooves.

[0014] By adopting the above technical solution, the connecting plate can move stably in the inner cavity of the connecting bin through the front and rear two groups of concave blocks, reducing the tilting phenomenon of the connecting plate and preventing the connecting plate from pulling the upper surface of the transmission chain downward.

[0017] Furthermore, the front and rear ends of the two support rods are rotatably connected to the front and rear walls of the inner cavity of the connecting bin through bearings.

[0018] By adopting the above technical solution, the support rod can support the sprocket so that the two sprockets can stably rotate in the connecting bin, and the transmission chain can stably rotate in the inner cavity of the connecting bin.

[0019] Furthermore, a through hole is opened on the left side of the connecting bin, and the transmission assembly passes through the through hole to the inside of the connecting bin and is rotatably connected thereto.

[0020] By adopting the above technical solution, the transmission component can pass through the through hole into the connecting bin, so that the transmission component can drive the left support rod to rotate.

When adding materials during the screening process, the staff does not need to lift the box cover, and can add materials to the screen box through the feed port, which can reduce the tediousness of adding materials.

[0033] Among them, a connecting hole is opened at the front end of the connecting warehouse 53, and the connecting plate 52 passes through the connecting hole to the interior of the connecting warehouse 53 and is slidably connected therewith, so that the connecting plate 52 can pass through the interior of the connecting warehouse 53 through the connecting hole, so as to drive the connecting plate 52 to move back and forth outside the connecting warehouse 53.

[0034] In addition, a connecting hole is provided at the rear end of the screen box 2, and a connecting plate 52 passes through the connecting hole to the interior of the screen box 2 and is slidably connected thereto, and the three connecting bins 53 of the three anti-blocking components are fixed to the rear end of the screen box 2, so that the three connecting plates 52 can pass through the three connecting holes into the interior of the screen box 2, so that the two upper connecting plates 52 can drive the two upper scrapers 51 to reciprocate at the top ends of the two screens 5, and the lower connecting plate 52 can drive the lower scraper 51 to reciprocate at the bottom of the inner cavity of the screen box 2, so that the scraper 51 can flip the material while also pushing the screened material into the discharge pipe 4.

[0035] In addition, two sliding grooves are provided on the front and rear walls inside the connecting bin 53, and the concave blocks 54 are slidably connected to the inner sides of the sliding grooves, so that the front and rear two groups of concave blocks 54 can move on the front and rear walls of the inner cavity of the connecting bin 53, so that the connecting plate 52 can move stably in the inner cavity of the connecting bin 53, so that the transmission chain 55 can stably drive the scraper 51 to move, to prevent the scraper 51 from pulling the transmission chain 55 downward.

[0036] See also Figure 3 The transmission component in this embodiment includes two sprockets 56, a connecting chamber 58, a support rod 57 fixedly installed on the inner side of the sprocket 56, and a motor 59 fixedly installed on the rear wall of the inner cavity of the connecting chamber 58.

[0040] It should be noted that the vibration table body 1, the transmission assembly 510 and the electrical components appearing in the text are all connected to the controller and the power supply. The control method of this embodiment is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also well known in the art, so the control method and circuit connection are no longer explained in detail in this utility model.

[0041] The working principle of the above embodiment is:

[0042] When in use, when the vibration table body 1 drives the screen box 2 to vibrate, the output end of the motor 59 drives the left support rod 57 to rotate through the transmission assembly 510, so that the left support rod 57 can drive the left sprocket 56 to rotate, and the left sprocket 56 drives the right sprocket 56 to rotate through the transmission chain 55, so that the transmission chain 55 can be stably transmitted in the inner cavity of the connecting bin 53, so that the transmission chain 55 can drive the connecting plate 52 to reciprocate in the inner cavity of the screen box 2 during the transmission process, that is, the connecting plate 52 can drive the scraper 51 to reciprocate in the screen box 2, so that the scraper 51 can turn over the material in the screen box 2, which can effectively improve the screening efficiency;

[0043] And when it is necessary to push the screened material into the discharge pipe 4, the staff adjusts the reciprocating distance of the scraper 51 through the control end so that the scraper 51 can push the material into the discharge pipe 4, which can avoid the screened material from accumulating in the screen box 2, and the two anti-blocking components at the upper end can turn over the material on the top of the two screens 5 and push it into the two discharge pipes 4 at the upper end, and the anti-blocking component at the lower end pushes the screened material into the discharge pipe 4 at the lower end, thereby effectively reducing the screened material from clogging the sieve holes of the screen 5 and reducing the screening efficiency; and when adding materials during the screening process, the staff does not need to lift the box cover, and can add materials to the screen box 2 through the feed port 3, which can reduce the cumbersomeness of adding materials.
