[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments:

[0023] As Figures 1-5 shown, the present utility model provides a closed bin type combined vibrating screen, which includes a support frame 1. A plurality of first support plates 3 and a plurality of second support plates 4 are fixedly installed on both sides of the support frame 1. The first support plates 3 and the second support plates 4 are symmetrically arranged. A climbing assembly 2 is arranged on the inner wall of the support frame 1. The climbing assembly 2 includes two first foot pads 2031, two second foot pads 2032, two first rotating shafts 2001, two second rotating shafts 2002 and a plurality of torsion springs 204. When the first foot pad 2031 is subjected to pressure, it rotates through the first rotating shaft 2001. When the second foot pad 2032 is subjected to pressure, it rotates through the second rotating shaft 2002. When the first rotating shaft 2001 and the second rotating shaft 2002 rotate, they can both squeeze a plurality of torsion springs 204. After the first foot pad 2031 and the second foot pad 2032 rotate by a certain amplitude, both ends of them can be attached to the first support plate 3 and the second support plate 4.

[0024] After the screening of the materials is completed, the staff then use their feet to press the first footrest plate 2031 in an inclined state. When the first footrest plate 2031 is squeezed, it can drive the first rotating shaft 2001 to rotate. At this time, the first rotating shaft 2001 can squeeze the torsion springs 204 at both ends. After the first footrest plate 2031 rotates by a certain amplitude, one of the first support plates 3 and the second support plate 4 can support the first footrest plate 2031, so that the first footrest plate 2031 is in a horizontal state under the squeezing state of the staff, thereby supporting the staff. Then, one of the staff's feet steps on the second footrest plate 2032. Similarly, the second footrest plate 2032 rotates and squeezes several torsion springs 204, so that the second footrest plate 2032 rotates to a horizontal state through the first support plate 3 and the second support plate 4. That is, the staff can lift their own height relative to the support frame 1 through the first footrest plate 2031 and the second footrest plate 2032, and then clean the residual materials or impurities in the equipment. It is possible to clean the equipment without carrying related equipment such as ladders, saving the physical consumption of the staff and improving the applicability;

[0025] After the materials inside the equipment are cleaned up, the staff first step on the first footrest plate 2031 with both feet in turn, and then step on the ground. When the staff's feet no longer exert pressure on the first footrest plate 2031 and the second footrest plate 2032, several torsion springs 204 can all release pressure, and several first rotating shafts 2001 and second rotating shafts 2002 reverse, and then drive the first footrest plate 2031 and the second footrest plate 2032 to reverse, so that the first footrest plate 2031 and the second footrest plate 2032 rotate to a state close to vertical, which can be easily unfolded when the climbing component 2 is used, and can also be self-stored after the screening box 9 is cleaned, without occupying extra space, further improving the applicability.

[0026] As Figures 1-3 shown, in one embodiment, the climbing component 2 further includes several centering grooves 207 and several socket rods 202. Both ends of several first rotating shafts 2001 and several second rotating shafts 2002 are rotatably connected to the support frame 1. One ends of several torsion springs 204 are respectively connected to several socket rods 202, and the other ends are connected to the support frame 1. Several first footrest plates 2031 and several second footrest plates 2032 are respectively fixedly connected to several torsion springs 204. Several socket rods 202 are respectively fixedly sleeved on several first rotating shafts 2001 and several second rotating shafts 2002. The climbing component 2 further includes several protective sleeves 210, several warning plates 205 and two support inclined plates 206. Several warning plates 205 are respectively fixedly installed on the tops of the first footrest plate 2031 and the second footrest plate 2032. Several protective sleeves 210 are all fixedly installed at one end of the support frame 1. The protective sleeve 210 is rotatably connected to the socket rod 202. Two support inclined plates 206 are respectively fixedly connected to the bottoms of two first footrest plates 2031.

[0027] A number of protective sleeves 210 can protect the torsion spring 204 and prevent it from rusting. A number of warning plates 205 can further control the distance when the staff steps on the footrest plate one 2031 and the footrest plate two 2032, reducing the possibility of stepping into the air and improving the safety protection effect.

[0028] As Figure 1 shown, in one embodiment, two connecting plates two 61 are fixedly installed on the outer walls on both sides of the support frame 1. Two mounting seats two 611 are fixedly installed on the top of the connecting plate two 61. One end of the mounting seat two 611 is connected to a return spring 7. The other end of the return spring 7 is connected to a mounting seat one 601. A connecting plate one 60 is fixedly installed between a number of mounting seats one 601. A screening box 9 and a vibration motor 8 are fixedly installed on the top of the connecting plate one 60. A screen 10 is fixedly installed at the bottom of the screening box 9. The central area of the connecting plate one 60 is hollow. One end of the screening box 9 is fixedly installed with a discharge pipe 11. The discharge pipe 11 has a certain amplitude relative to the support frame 1. The discharge pipe 11 is inclined. A base 101 is fixedly installed at the bottom of the support frame 1.

[0029] When it is necessary to screen the materials, the staff first move the equipment near the feeding equipment, and then make the feeding equipment pour the materials into the screening box 9. After the materials reach the specified weight, start the vibration motor 8. After the vibration motor 8 operates, it drives the connecting plate one 60 and the screening box 9 to vibrate through a number of return springs 7, a number of mounting seats one 601 and a number of mounting seats two 611. Then, when the screening box 9 vibrates, the smaller particles of impurities are discharged through the screen 10. The screened materials are discharged through the discharge pipe 11, that is, the materials and impurities can be discharged separately to achieve the screening function.

[0030] As Figure 1 、 Figures 4-5 shown, in one embodiment, an aggregate hopper 5 is fixedly installed on the inner wall of the support frame 1. The inner wall of the aggregate hopper 5 is inclined. One end of the aggregate hopper 5 is provided with a notch, and a closing plate 501 is movably connected in the notch.

[0031] When the screening box 9 vibrates, the smaller particles of impurities are discharged through the screen 10 into the aggregate hopper 5. At this time, the closing plate 501 cooperates with the aggregate hopper 5 to be able to close the discharge port of the aggregate hopper 5, so that the impurities can be stored between the aggregate hopper 5 and the closing plate 501. The screened materials are discharged through the discharge pipe 11, that is, the materials and impurities can be discharged separately to achieve the screening function. By setting the inside of the aggregate hopper 5 to be arc-shaped, the impurities can fall along the inclined amplitude into the central area of the aggregate hopper 5 for storage, improving the collection effect.

[0032] Next, specifically describe the working principle of this closed bin type combined vibrating screen:

[0033] First, install the device in a closed bin. When screening materials is required, the staff first move the device near the feeding device, and then enable the feeding device to pour the materials into the inside of the screening box 9. After the materials reach the specified weight, start the vibration motor 8. After the vibration motor 8 operates, it drives the connecting plate one 60 and the screening box 9 to vibrate through a number of reset springs 7, a number of mounting seats one 601 and a number of mounting seats two 611. As a result, when the screening box 9 vibrates, it discharges the smaller particles and impurities through the screen 10 into the aggregate hopper 5. At this time, the closing plate 501 cooperates with the aggregate hopper 5 to close the discharge port of the aggregate hopper 5, so that the impurities can be stored between the aggregate hopper 5 and the closing plate 501. The screened materials are discharged through the discharge pipe 11, that is, the materials and impurities can be discharged separately, achieving the screening function;

[0034] After the screening of the materials is completed, turn off the vibration motor 8. Then, the staff use their feet to press the inclined footrest plate one 2031. When the footrest plate one 2031 is squeezed, it can drive the connected socket rod 202 and the rotating shaft one 2001 to rotate. At this time, when the socket rod 202 rotates, it can squeeze the torsion springs 204 at both ends. After the footrest plate one 2031 rotates a certain amplitude, one of the support plates one 3 and the support plate two 4 can support the footrest plate one 2031, so that the footrest plate one 2031 is in a horizontal state under the squeezing state of the staff, thus supporting the staff. Then, one of the staff's feet steps on the footrest plate two 2032, so that the footrest plate two 2032 drives the connected socket rod 202 and the rotating shaft two 2002 to rotate. At this time, the socket rod 202 will also squeeze the connected torsion spring 204. Then, rotate the footrest plate two 2032 to a horizontal state through the support plate one 3 and the support plate two 4. That is, the staff can lift their own height relative to the support frame 1 through the footrest plate one 2031 and the footrest plate two 2032, and then clean the residual materials or impurities in the screening box 9. It is possible to clean the screening box 9 without carrying related equipment such as ladders, saving the physical consumption of the staff and improving the applicability;

[0035] After the materials inside the screening box 9 are cleaned up, the staff first step on the footrest plate one 2031 with both feet in turn, and then step on the ground. When the staff's feet no longer exert pressure on the footrest plate one 2031 and the footrest plate two 2032, a number of torsion springs 204 can all release the pressure and drive a number of socket rods 202 to reverse. After a number of socket rods 202 reverse, they drive the rotating shaft one 2001 and the rotating shaft two 2002 to reverse, and drive the footrest plate one 2031 and the footrest plate two 2032 to reverse, so that the footrest plate one 2031 and the footrest plate two 2032 rotate to a state close to vertical. It can be easily unfolded when the climbing component 2 is used, and can also be self-stored after the screening box 9 is cleaned, without occupying extra space, further improving the applicability.

[0036] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
