For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0021] Figure 1 to Figure 5 It is the best embodiment of the utility model, and the following Figure 1 ~Attached Figure 5 The utility model is further described.

[0022] The utility model discloses a vibrating screen for producing granular rubber, comprising a support frame 1 and a screen box 2, wherein the support frame 1 is connected to the screen box 2 through four first springs 3, and the support frame 1 is in an inclined state. The top of the screen box 2 is open, and a rotatable sealing door 4 is arranged on the top of the screen box 2. A vibration motor 5 for driving the screen box 2 to vibrate is arranged at the bottom of the screen box 2. A screen 6 is arranged in the screen box 2. Four groups of limiting components 7 are symmetrically arranged on the top of the screen box 2, and the four groups of limiting components 7 are respectively provided with an extrusion component 8, a fixing component 9 and a connecting component 10. The four groups of connecting components 10 are connected to the screen 6, and the fixing component 9 is extruded by the extrusion component 8 moving along the limiting component 7, so that the fixing component 9 can move along the limiting component 7 into the connecting component 10 and limit the connecting component 10.

[0023] The limiting assembly 7 includes a mounting groove 701, a connecting groove 702 and a slide groove 703. The mounting groove 701 is provided at the top of the screen box 2, and the connecting groove 702 is provided on the inner wall of one side of the mounting groove 701. The slide groove 703 is provided at the top of the screen box 2 and is located next to the mounting groove 701, and the connecting groove 702 is connected to the slide groove 703.

[0024] The extrusion assembly 8 includes a support rod 801, a second spring 802 and an inclined plate 803. The inclined plate 803 is disposed in the slide groove 703 and slidably cooperates with the slide groove 703. The inclined plate 803 is inclined downwardly near the connecting groove 702. One end of the support rod 801 is fixedly connected to the top of the inclined plate 803. The second spring 802 is sleeved on the support rod 801, one end of the second spring 802 is fixedly connected to the top of the inclined plate 803, and the other end is fixedly connected to the slide groove 703. The other end of the support rod 801 is located outside the slide groove 703.

[0025] The fixing assembly 9 includes a connecting rod 901, a fixing rod 902, a slider 903 and a third spring 904. The slider 903 is disposed in the connecting groove 702 and is slidably matched with the connecting groove 702. One end of the fixing rod 902 and the connecting rod 901 are fixedly connected to both sides of the slider 903 respectively. The fixing rod 902 and the connecting rod 901 are symmetrically arranged. The third spring 904 is sleeved on the connecting rod 901, and one end of the third spring 904 is fixedly connected to the connecting groove 702, and the other end is fixedly connected to the slider 903.

[0026] The connection assembly 10 includes a connection block 1001, a connection plate 1002 and a connection hole 1003. The connection plate 1002 is fixedly connected to the screen 6, and the connection block 1001 is fixedly connected to the connection plate 1002. The connection plate 1002 is slidably matched with the inner wall of the screen box 2, the connection block 1001 is slidably matched with the installation groove 701, and the connection hole 1003 is opened on the connection block 1001.

[0027] In this embodiment, in the initial state, the sealing door 4 does not seal the top opening of the screen box 2, the other end of the support rod 801 is located outside the slide groove 703, one end of the fixed rod 902 is located in the slide groove 703, the connecting rod 901 is located in the connecting groove 702, the connecting hole 1003 coincides with the installation groove 701, and the screen 6 is located in the screen box 2.

[0028] At this time, the staff will rotate the sealing door 4 so that the sealing door 4 seals the opening at the top of the screen box 2. When the sealing door 4 contacts the support rod 801 and squeezes the support rod 801, the end of the support rod 801 located outside the slide groove 703 enters the slide groove 703, and the support rod 801 drives the inclined plate 803 to move, and the inclined plate 803 moves along the slide groove 703 and stretches the second spring 802. When the inclined surface of the inclined plate 803 contacts the fixed rod 902, the fixed rod 902 slides along the inclined surface of the inclined plate 803. The inclined plate 803 squeezes the fixed rod 902, and the fixed rod 902 moves and drives the slider 903 and the connecting rod 901 to move, so that the third spring 904 is squeezed by the slider 903. The connecting rod 901 enters the connecting hole 1003 from the connecting groove 702, and the connecting block 1001 will not be separated from the installation groove 701 through the connecting rod 901, the connecting hole 1003 and the connecting groove 702, and the screen 6 will be fixed in the screen box 2. At this time, the sealing door 4 completely seals the top opening of the screen box 2, and the sealing door 4 is fixed by the lock buckle on the screen box 2.

[0029] There are two feed pipes and a dust suction pipe on the top of the sealing door 4. The two feed pipes are externally connected to the material conveying pipe, so that the material enters the screen box 2 from the feed pipe and falls on the screen 6. The dust suction pipe is externally connected to the fan, and the dust in the screen box 2 is sucked out through the dust suction pipe. At this time, the vibration motor 5 is started. The vibration motor 5 is an existing device and is not explained here.

[0030] The eccentric weight inside the vibration motor 5 generates a strong centrifugal force when rotating at high speed, and this centrifugal force is converted into the vibration of the screen box 2. The fixed screen 6 and the material on the screen 6 are driven to vibrate through the vibration of the screen box 2. Because the support frame 1 is in an inclined state, the screen box 2 and the screen 6 are both inclined, so that the materials of different sizes move toward the discharge pipe of the screen box 2 along the slope of the screen 6 while vibrating. Small materials will pass through the mesh of the screen 6 and fall into the screen box 2, and move toward the discharge pipe of the screen box 2 along the slope inside the screen box 2. Large materials stay on the screen 6.

[0031] After the screening is finished, the staff needs to take out the material on the screen 6. The staff unlocks the lock of the sealing door 4 on the screen box 2 and rotates the sealing door 4. When the sealing door 4 no longer resists the support rod 801, the second spring 802 rebounds, and the second spring 802 drives the inclined plate 803 and the support rod 801 to move, so that the support rod 801 and the inclined plate 803 return to the initial state. When the inclined plate 803 moves, the third spring 904 rebounds and drives the slider 903, the fixed rod 902 and the connecting rod 901 to return to the initial state, so that the connecting rod 901 enters the connecting groove 702 from the connecting hole 1003, and the connecting block 1001 is no longer connected to the mounting groove 701. At this time, the staff takes the screen 6 and the material on the screen 6 out of the screen box 2, and drives the connecting block 1001 and the connecting plate 1002 to move synchronously, so that the connecting block 1001 is separated from the mounting groove 701. The staff does not need to use auxiliary tools to disassemble the screen 6, which improves the work efficiency of replacing the screen 6.

[0032] In this embodiment, the first spring 3 plays a role in supporting and fixing the screen box 2. Through the compression and stretching of the first spring 3, the screen box 2 can remain stable when subjected to an exciting force, thereby avoiding displacement or damage of the equipment due to excessive vibration.

[0033] Specifically, the screen box 2 is sprayed with anti-corrosion paint.

[0034] In this embodiment, spraying anti-corrosion paint can prevent the screen box 2 from rusting, thereby increasing the service life.

[0035] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
