Description

Technical Field

[0001] This patent relates to the technical field of vibrating screens, specifically a vibrating screen with an anti-blocking structure. Background Art

[0002] Vibrating screens are used for particle screening of materials. In order to prevent particles from clogging in the screen, existing vibrating screens will set insertion rods on one side of the screen. By inserting the insertion rods into the screen, the particles clogging in the screen are pushed out. However, the insertion rods need to be controlled by an external telescopic mechanism, which increases the cost and installation space of the overall vibrating screen and cannot be controlled by the electric drive mechanism carried by itself. Therefore, we propose a vibrating screen with an anti-blocking structure. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of this patent is to provide a vibrating screen with an anti-blocking structure. In this patent, a horizontal rail is installed in the U-shaped seat, and a fixed block with an inclined surface is installed at the top of the side wall of the horizontal rail. An inclined plate that can move up and down relative to the box body is arranged inside the box body. A vertical rod is installed at the bottom of the inclined plate, and the bottom end of the vertical rod fits on the inclined surface of the fixed block. When the motor drives the box body to move left and right, the vertical rod at the bottom of the inclined plate can move relative to the inclined surface, thereby driving the inclined plate to move upward, and the particles in the screen are pushed out by the insertion rod. Through this setting, no external electric drive mechanism is required, the cost and installation space are reduced, and the structure is ingeniously set and has strong practicability.

Detailed implementation manners

[0017] The following further elaborates on this patent in combination with specific embodiments. It should be understood that these embodiments are only used to illustrate this patent and not to limit the scope of this patent. In addition, it should be understood that after reading the content taught in this patent, those skilled in the art can make various changes or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0018] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 are the structural schematic diagrams of this patent. A vibrating screen with an anti-blocking structure includes a U-shaped seat 1 and a box body 6. A horizontal rail 2 is fixedly installed inside the U-shaped seat 1. A motor 3 is fixedly installed on the right side of the bottom of the U-shaped seat 1. The top end of the rotating shaft of the motor 3 is fixedly installed with a disc 4. The right side of the top of the disc 4 is hinged with a connecting plate 5 through a pin shaft. The left end of the connecting plate 5 is hinged to the right end of the outer side wall of the box body 6. Sliding holes 7 are provided at both the left and right ends of the side wall of the box body 6. The sliding holes 7 are slidably installed on the horizontal rail 2. A discharge pipe 8 is embedded in the right side wall of the box body 6. A screen 9 is fixedly installed on the inner side wall of the box body 6. An inclined plate 10 is provided inside the box body 6. An inserting rod 11 is integrally formed at the top of the inclined plate 10. A column 12 is fixedly installed on the right side of the bottom of the inclined plate 10. A fixing ring 13 is sleeved on the side wall of the column 12. The right end of the fixing ring 13 is fixedly installed on the right end of the inner side wall of the box body 6 through a connecting rod. A vertical rod 14 is fixedly installed at the bottom of the inclined plate 10. A fixing block 15 is integrally formed at the top of the side wall of the horizontal rail 2. The top of the fixing block 15 is provided with an inclined surface. The bottom end of the vertical rod 14 is attached to the inclined surface.

[0019] The diameter of the inserting rod 11 is smaller than the aperture on the screen 9.

[0020] It is slidably installed on the inner side wall of the fixing ring 13 through the side wall of the column 12, and is used to limit the movement track of the inclined plate 10 and the inserting rod 11, so that the inserting rod 11 can only move up and down relative to the screen 9.

[0021] Specifically, a spherical surface 16 is provided at the bottom end of the vertical rod 14, and the spherical surface 16 is attached to the inclined surface.

[0022] The setting of the spherical surface 16 is used to increase the sliding effect between the bottom end of the vertical rod 14 and the inclined surface.

[0023] Specifically, a circular plate 17 is integrally formed at the bottom end of the upright column 12, and a spring 18 is sleeved on the side wall of the upright column 12. The two ends of the spring 18 are respectively fixedly installed on the fixed ring 13 and the circular plate 17.

[0024] After the inclined plate 10 and the insertion rod 11 move upward, the spring 18 is compressed. After the box body 6 drives the inclined plate 10 to move to the right, the elastic rebound effect of the spring 18 can make the inclined plate 10 and the insertion rod 11 move downward, preventing the insertion rod 11 from getting stuck in the screen 9.

[0025] Specifically, a baffle 19 is fixedly installed at the left end of the screen 9.

[0026] The setting of the baffle 19 can prevent the material particles from falling from the left end of the screen 9.

[0027] Specifically, the connecting plate 5 includes a first plate body 20, a second plate body 21 and a bearing 24. Semi-circular grooves 22 are provided at the upper and lower left and right ends of the opposite sides of the first plate body 20 and the second plate body 21. A positioning block 23 is integrally formed on the inner wall of the semi-circular groove 22. The bearing 24 is located in the two semi-circular grooves 22. Positioning grooves 25 are provided at both ends of the outer ring of the bearing 24. The positioning block 23 is inserted into the positioning groove 25, and the first plate body 20 and the second plate body 21 are connected by bolts and nuts.

[0028] The inner side wall of the inner ring of the bearing 24 can be fixedly connected to the pin shaft. The two pin shafts are the connecting pin shafts of the connecting plate 5 and the disc 4, and the connecting plate 5 and the box body 6.

[0029] Specifically, wheel grooves 26 are provided at the upper and lower ends of the side wall of the horizontal rail 2. Installation grooves 27 are provided at the upper and lower ends of the inner side wall of the sliding hole 7. A roller 28 is connected to the installation groove 27 through a rotating shaft. The roller 28 is rotatably installed in the wheel groove 26, and the inner side wall of the sliding hole 7 does not contact the side wall of the horizontal rail 2.

[0030] If it directly slides on the horizontal rail 2 through the inner side wall of the sliding hole 7, it is in a sliding state at this time, with relatively serious wear and low service life. If the roller 28 is rotatably installed in the wheel groove 26, it is in a rolling state at this time, which can greatly reduce the wear degree.

[0031] Working principle: Material particles are put into the feeding hopper at the top of the box body 6. The disc 4 is controlled by the motor 3 to rotate. The disc 4 can drive the connecting plate 5 to move left and right, thereby driving the box body 6 to vibrate left and right. The particles that can pass through the screen 9 will fall, and those that cannot pass will fall from the discharge pipe 8. At the same time, the box body 6 will drive the inclined plate 10 to move left and right through the fixed ring 13. The bottom end of the vertical rod 14 moves relative to the inclined surface on the fixed block 15, thereby driving the vertical rod 14, the inclined plate 10 and the insertion rod 11 to move upward. The insertion rod 11 is inserted into the screen 9 to eject the particles blocked in the screen 9.

[0032] It should be noted that the device structure and drawings of this patent mainly describe the principle of this patent. Based on the technical principle of this design, the settings of the power mechanism, power supply system, control system, etc. of the device are not fully described. However, on the premise that those skilled in the art understand the principle of the above patent, the specific details of its power mechanism, power supply system, and control system can be clearly obtained.

[0033] In this patent, a horizontal rail is installed inside the U-shaped seat, and a fixed block with an inclined surface is installed at the top of the side wall of the horizontal rail. An inclined plate that can move up and down relative to the box body is provided inside the box body. A vertical rod is installed at the bottom of the inclined plate, and the bottom end of the vertical rod fits on the inclined surface of the fixed block. When the motor drives the box body to move left and right, the vertical rod at the bottom of the inclined plate can move relative to the inclined surface, thereby driving the inclined plate to move upward, and ejecting the particles in the sieve through the insertion rod. Through this setting, there is no need for an external electric drive mechanism, which reduces costs and installation space, and the structural setting is ingenious and has strong practicability.
