Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of screening equipment accessories, specifically relating to a screen machine anti-tipping bracket with rubber shock-absorbing blocks. Background Technology
[0002] The double-layer tension screen is a screening device that utilizes the principle of sub-resonance of two masses. It consists of circular vibration generated by the rotation of an eccentric block and elliptical vibration generated by a floating screen frame. The material is thrown through the relaxation and tension motion of the elastic screen surface. This screening equipment is particularly suitable for screening sticky and wet materials and is widely used in waste treatment, mining, building materials and other fields.
[0003] However, the existing double-layer tension screen is connected to the support base by shock-absorbing springs. When the viscosity of the coal gangue is normal, the connection can be reliable. However, if the viscosity of the coal gangue is high and the screening efficiency is poor, the staff may not notice it in time, which can easily cause the coal gangue to accumulate and tilt the screen body, causing the screen body to tilt and potentially leading to safety accidents and posing many safety hazards. Therefore, the applicant proposes a screen anti-tipping bracket with rubber shock-absorbing blocks to solve the above problems. Utility Model Content

[0030] Example 1:
[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the anti-tipping support for the screening machine with rubber shock absorbers includes:
[0032] Screening machine body 1 and anti-tipping mechanism 2 assembled on screening machine body 1;
[0033] The anti-tipping mechanism 2 includes a support assembly 4 and a support assembly 3 mounted on the support assembly 4;
[0034] The support assembly 4 includes a mounting base 42 fixedly installed on the screen body 1, and ribs 41 distributed symmetrically are fixedly installed on the top of the mounting base 42.
[0035] The support assembly 3 includes a vertical plate 31 inserted between stiffening plates 41. A limiting frame 35 is fixedly installed on one side of the vertical plate 31, and a shock-absorbing block body 33 is inserted into the inside of the limiting frame 35.
[0036] As can be seen from the above, by fixing the mounting base 42 to both ends of the original support on the screen body 1 during use, the entire anti-tipping mechanism 2 can provide limit on both ends of the spring seat on the screen body 1. When the screen body on the screen body 1 is displaced, the spring seat can contact the shock absorber body 33. Through the support of the vertical plate 31, the displacement of the screen body can be blocked, and the abnormal displacement of the screen body can be controlled. This ensures that the screen body plays a safety protection role when abnormal displacement occurs, reduces the accident rate, and gives the staff sufficient time to deal with the situation. When a malfunction occurs, it can effectively ensure that the screen body will not immediately tip over and cause an accident, thus effectively reducing safety hazards.
[0037] By inserting the upright plate 31 between the stiffening plates 41, the stiffening plates 41 can provide support for the upright plate 31, making the installation operation convenient and quick. At the same time, the upright plate 31 can be pulled upward to separate from the stiffening plates 41, allowing personnel to easily replace and maintain the damaged damping block body 33, effectively improving the performance and bringing more convenience to the maintenance work. The limiting frame 35 can limit the periphery of the damping block body 33, which can suppress the deformation of the damping block body 33 when it is squeezed, and prevent the damping block body 33 from being displaced due to excessive deformation caused by squeezing.
[0038] Depend on Figure 4 and Figure 6 It can be seen that a limiting groove 45 is provided on the stiffening plate 41, and a slot 32 for the limiting groove 45 to be inserted is provided at the bottom of the upright plate 31.
[0039] As can be seen from the above, by inserting the slot 32 into the limiting groove 45, the slot 32 and the limiting groove 45 can be engaged, and the upright plate 31 and the stiffening plate 41 can be quickly connected and fixed, so that the stiffening plate 41 can support the upright plate 31.
[0040] For details, please refer to Figure 6 As shown, a first reinforcing rib 44 is fixedly installed between the reinforcing ribs 41 at one side of the limiting groove 45, and a second reinforcing rib 46 is fixedly installed between the reinforcing ribs 41 at the other side of the limiting groove 45.
[0041] As can be seen from the above, the structural strength between the stiffening plates 41 can be improved by the first stiffening rib 44 and the second stiffening rib 46, which can improve the supporting strength of the upright plate 31 and make the stiffening plate 41 less prone to deformation when subjected to large compressive force.
[0042] For details, please refer to Figure 4 and Figure 6 As shown, mounting holes 43 are provided at the four corners of the mounting base 42, and the shock absorber body 33 is made of rubber material.
[0043] As can be seen from the above, by using bolts and mounting holes 43, the mounting base 42 can be easily fixed to both ends of the original support on the screen body 1 without changing the structure of the screen body 1. The rubber damping block body 33 can cause the spring seat on the screen body to collide with the damping block body 33 when the screen body on the screen body 1 is displaced. The damping block body 33 can buffer the impact force generated during the collision and protect the spring seat on the screen body from damage.
[0044] Example 2:
[0045] refer to Figure 5 As shown, a hexagonal head screw 39 is installed through the interior of the damping block body 33. The hexagonal head screw 39 extends out of one side of the upright plate 31 and is fixed to the upright plate 31 by a hexagonal nut 37.
[0046] As can be seen from the above, by inserting the hexagonal head screw 39 into the damping block body 33 and having one end of the hexagonal head screw 39 protrude from the vertical plate 31, and by screwing the hexagonal nut 37 onto one end of the hexagonal head screw 39, the hexagonal nut 37 can be pressed against one side of the vertical plate 31, which can easily fix the damping block body 33 to the vertical plate 31, making it less likely for the damping block body 33 to fall off.
[0047] refer to Figure 5 As shown, the inside of the damping block body 33 is provided with a mounting groove 34 and a socket 38 for the internal hexagonal head screw 39 to pass through. The socket 38 and the mounting groove 34 are interconnected, and the diameter of the mounting groove 34 is larger than that of the socket 38.
[0048] As can be seen from the above, the screw of the socket head cap screw 39 can pass through the socket 38, and the socket head cap screw 39 can be limited by the mounting groove 34, so that the socket head cap screw can be hidden in the mounting groove 34 and will not be exposed, thus avoiding affecting the performance of the damping block body 33.
[0049] refer to Figure 5 As shown, a fixing hole 36 is provided on the upright plate 31, and the fixing hole 36 corresponds to the insertion hole 38.
[0050] As can be seen from the above, by inserting the hexagonal head screw 39 into the socket 38, one end of the hexagonal head screw 39 can extend out from the fixing hole 36, which can easily fix the damping block body 33 in the limiting frame 35 and prevent displacement.
[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
