[0002] The working part of a cylindrical screen is cylindrical, and the entire screen rotates around the axis of the cylinder. Under normal circumstances, the axis is installed at a small angle. The material is fed in from one end of the cylinder. Fine-grained materials pass through the screen holes on the working surface of the cylinder, while coarse-grained materials are discharged from the other end of the cylinder. Cylindrical screens are a type of screening equipment mainly used for dewatering river sand and fine sand. The processing capacity of a cylindrical screen can reach 20-200 cubic meters per hour. Depending on the material box and the usage environment, an open or closed structure can be selected. The screening aperture is generally 60-200 mesh. Currently, the support frame of a cylindrical screen is basically fixed, and the screening capacity can only be adjusted by the input amount, not by the cylindrical screen itself, which is somewhat inconvenient in use.

[0018] This utility model provides an adjustable cylindrical screen support, including a base, a support assembly and a drive assembly on the upper part of the base, and a screen cylinder rotatably mounted on the upper part of the support assembly and drive assembly. The screen cylinder can be tilted at an adjustable angle under the drive of the support assembly. An inlet and an outlet are respectively provided at both ends of the screen cylinder, and a plurality of screen holes are evenly arranged on the screen cylinder. Track rings are provided at both ends of the screen cylinder, and guide plates are fixedly installed on both sides of the track rings. The drive assembly includes two mounting seats fixedly mounted on one end of the upper part of the base, and drive wheels are rotatably mounted on both mounting seats. A motor and a reducer connected by a spline are also mounted on the base, and the output shaft of the reducer is connected to the drive wheels. The two drive wheels are evenly positioned... The support assembly includes a horizontal rail fixedly installed at the other end of the upper part of the base. Two sliding seats are movably arranged on the horizontal rail, symmetrically located at both ends of the horizontal rail. A tire seat is rotatably hinged to the sliding seat. The tire seat is designed with a V-shaped structure and has two tires rotatably mounted on it. The tires are all located in another track ring. The base is also provided with two hinged seats, each of which is connected to a hydraulic cylinder by a hinge. The other end of the piston rod of the hydraulic cylinder is hinged to the sliding seat. Several brackets are also provided at the lower part of the base. A collection plate is also provided on the base. The collection plate is located between the screen cylinder and the base. The collection plate is inclined and has a discharge gate at its lowest point.

[0019] The first embodiment of this utility model is as follows:

[0020] An adjustable cylindrical screen support includes a base, with several supports at the bottom of the base to support the base and maintain a certain gap from the ground. A collection plate is also provided on the base. The two sides of the collection plate are vertical structures, and the bottom is an inclined structure. The collection plate is located between the screen cylinder and the base. A discharge gate is provided at the lowest point of the collection plate. Fine materials discharged from the screen holes on the screen cylinder will fall onto the collection plate and then be collected at the discharge gate under the action of gravity for centralized discharge. Workers can collect the materials at this point.

[0021] The base is equipped with a support assembly and a drive assembly. A screen cylinder is rotatably mounted on the support assembly and drive assembly. The screen cylinder has a number of screen holes evenly distributed on it. The screen hole diameter is set to 60-200 mesh, allowing fine materials to pass through and be discharged. The screen cylinder has an inlet and an outlet at both ends. The material is fed into the screen cylinder from the inlet by a belt conveyor. During the rotation of the screen cylinder, fine materials are discharged from the screen holes, while coarse materials gradually move to the outlet and are then discharged.

[0022] Both ends of the screen cylinder are equipped with track rings, and guide plates are fixedly installed on both sides of the track rings. The guide plates can prevent the tires and drive wheels from detaching from the track rings.

[0023] The drive assembly is used to drive the screen cylinder to rotate. It includes two mounting seats fixedly installed at one end of the upper part of the base. The two mounting seats are symmetrically arranged on both sides of the screen cylinder to ensure the stability of the screen cylinder. Each mounting seat is equipped with a drive wheel in a rotatable manner. The base is also equipped with a motor and a reducer connected by a spline. The output shaft of the reducer is connected to the drive wheel. Both drive wheels are located in one of the track rings. The two motors can work simultaneously or independently. On the one hand, this can improve the drive power. On the other hand, if one motor fails, the other motor can continue to work to ensure that the operation is not interrupted.

[0024] The support assembly supports the screen cylinder and adjusts its tilt angle. It includes a horizontal rail fixedly mounted on the other end of the upper part of the base. Two sliding seats are movably mounted on the horizontal rail, symmetrically located at both ends of the horizontal rail. Tire seats are rotatably hinged to the sliding seats. The tire seats are designed with a V-shape and have two rotatably mounted tires. The tires are located inside another track ring and are in contact with the track ring. When the sliding seats move towards each other on the horizontal rail, the height of this end of the screen cylinder increases while the height of the other end remains unchanged, thereby adjusting the angle of the screen cylinder. At this time, the height of this end increases, making the tilt angle larger and accelerating the movement speed of the material in the screen cylinder. At this time, the speed of the drive wheel is adjusted, thereby increasing the screening speed while ensuring the screening rate.

[0025] Two hinge seats are also provided on the base near the horizontal rail. Each of the two hinge seats is connected to a hydraulic cylinder by a hinge. The other end of the piston rod of the two hydraulic cylinders is hinged to the two sliding seats respectively. The hydraulic cylinder drives the sliding seats to move on the horizontal rail. The above structure is not shown in the attached drawing due to obstruction, but the specific arrangement of the structure can be clearly described from the text.

[0026] The main technical solution claimed in this application is an adjustable bracket, which means that the improvement is mainly made to the bracket part of the cylindrical screen device. Other conventional structures of cylindrical screens not described in this application are common knowledge in this technical field. Even if they are not described, the technical problem to be solved by this application can be achieved by combining them with common knowledge, so as to meet the requirements of Article 26, Paragraph 3 of the Patent Law.
