[0002] The emergence of bidirectional roller screens has solved the problems of traditional roller screens, such as single conveying direction and low screening efficiency. However, the following problems still exist during use:

[0003] Because it supplies material in two directions at the same time, the amount of material fed into the hopper increases, making it more prone to blockage. The lack of a clearing mechanism will affect the screening efficiency, and the lack of a speed control mechanism makes it inconvenient to adjust the feeding speed in each direction. Furthermore, if a malfunction occurs in one direction, the entire device needs to be shut down, making it quite inconvenient to use.

Detailed Implementation

[0031] Example: Figures 1 to 6 As shown, a bidirectional roller screen includes a screen body 1. A feed channel 2 is fixedly installed on the top of the screen body 1, and a feed funnel 3 is fixedly installed on the top of the feed channel 2 to facilitate feeding materials into the device. Three unblocking mechanisms 4 are rotatably connected inside the feed channel 2 to unblock the feed channel 2 and prevent blockage. Two adjusting plates 5 are slidably connected inside the feed channel 2. By adjusting the position of the adjusting plates 5, the size of the feed inlet in that direction can be adjusted, thereby adjusting the feed speed in that direction. A drive mechanism 6 is fixedly installed on both sides of the feed channel 2 to drive the adjusting plates 5 to adjust their positions.

[0032] The screen body 1 has several rollers that are rotatably connected inside. The rollers are not shown in the figure and will not be described in detail here. Technicians can implement the plan accordingly. A baffle 11 is fixedly installed inside the screen body 1. Both sides of the top of the baffle 11 are chamfered. By setting the baffle 11, the feed in that direction can be blocked after the adjusting plate 5 is close to the baffle 11. This allows for repair and maintenance after a component fails in that direction without affecting the screening work in the other direction. The chamfering can prevent material from accumulating on the baffle 11.

[0033] A chute 21 is provided on both sides of the feeding channel 2 to guide the movement of the adjusting plate 5. The outside of the adjusting plate 5 is adapted to the inside of the chute 21, and the outside of the adjusting plate 5 is slidably connected to the inside of the corresponding chute 21.

[0034] The drive mechanism 6 includes two hydraulic cylinders 61, which are symmetrically distributed. Each of the two hydraulic cylinders 61 is rotatably connected to a first rotating block 62 on one side. The bottom of the two first rotating blocks 62 is fixedly installed on one side of the feed channel 2. The extension and retraction of the hydraulic cylinders 61 drives the adjusting plate 5 to move inside the slide 21, thereby adjusting the feeding speed in the corresponding direction.

[0035] The output end of the hydraulic cylinder 61 is rotatably connected to a second rotating block 63, and one side of the second rotating block 63 is fixedly installed on one side of the adjusting plate 5.

[0036] The unblocking mechanism 4 includes a motor 41, one side of which is fixedly installed on one side of the feed channel 2. A rotating shaft 42 is fixedly installed at the output end of the motor 41. Several unblocking rods 43 are fixedly connected to the outer surface of the rotating shaft 42. The unblocking rods 43 are linearly and evenly distributed. The unblocking rods 43 are driven to rotate by the rotation of the motor 41, which agitates the material and avoids accumulation and blockage. Two of the motors 41 rotate in both directions between 70 and 90 degrees to prevent the unblocking rods 43 from colliding with the screen body 1 and the feed channel 2.

[0037] Three rotating holes 22 are provided on both sides of the feeding channel 2. The shape and size of the rotating shaft 42 are adapted to the shape and size of the rotating holes 22. The external rotating shaft 42 is rotatably connected to the inside of two of the rotating holes 22.

[0038] Several mounting holes are provided on one side of the screen body 1. The outside of the roller is rotatably connected to the inside of two of the mounting holes. The implementation of the screen body 1 can refer to the screen body in patent CN219232998U. This utility model has a baffle 11 installed on its basis. The difference in the position and number of mounting holes will not affect the technicians to implement the plan. Since the roller, observation window and other structures have not been improved in this utility model, they will not be described in detail here, and they are not further shown in the figure. The focus of this utility model is on the improvement of the feeding part, so it will not affect the technicians to implement the plan.

[0039] Baffle 11 is located above two of the rollers, and the rollers are arranged symmetrically.

[0040] A feeding chute is provided on one side of the screen body 1, and the baffle 11 is located below the feeding chute.

[0041] The electrical components of this utility model are all connected to an external main controller and 220V AC mains power via a transformer. The main controller can be a conventional known device such as a computer. The electrical components provided in this utility model are only used according to the structural characteristics of the product in this technical solution. The product will be adjusted and modified after purchase to better match and conform to the technical solution of this utility model. It is an optimal application of this technical solution. The product model can be replaced and modified according to the required technical parameters. It is well known to those skilled in the art. Therefore, those skilled in the art can clearly obtain the corresponding usage effect through the technical solution provided by this utility model.

[0042] A bidirectional roller screen works on the following principle:

[0043] 1) When using this utility model, the material is added into the feed hopper 3 and enters the feed channel 2 under the action of gravity. Then, the screen body 1 is screened in both directions. The position of the adjusting plate 5 can be adjusted by the extension and retraction of the hydraulic cylinder 61, thereby adjusting the distance between the plate 5 and the baffle 11 to adjust the feeding speed in that direction. The two adjusting plates 5 are relatively independent, so unidirectional adjustment can be achieved. The material inside the feed channel 2 and at the feed inlets in both directions is fluctuated by the three unblocking mechanisms 4 to avoid accumulation and blockage.

[0044] 2) When a fault occurs in one direction, the adjusting plate 5 that controls the feed rate in that direction can be pressed against the baffle 11 to block that direction and prevent further conveying. This allows for repair work without affecting the work in the other direction, ensuring the practicality of the device.

[0045] Compared with the prior art, the present invention has the following advantages:

[0046] This invention can adjust the position of the adjusting plate 5 by extending and retracting the hydraulic cylinder 61, thereby adjusting the distance between the plate 5 and the baffle 11 to adjust the feeding speed in that direction. The two adjusting plates 5 are relatively independent, thus enabling unidirectional adjustment. The three unblocking mechanisms 4 respectively ripple the material inside the feeding channel 2 and at the feeding ports in both directions to avoid accumulation and blockage. In the event of a unidirectional failure, the adjusting plate 5 can be pressed against the baffle 11 to seal the blockage. Maintenance does not affect the continued operation in the other direction, ensuring the practicality of the device.
