[0003] In the aforementioned patents or prior art, when the sieve barrel is screening clay blocks, the clay blocks may easily cause the sieve holes to become clogged due to their high moisture content or the presence of a large number of particles close to the size of the sieve holes, thereby affecting the screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a drum screen for clay blocks that is easy to clean, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drum screen for clay blocks that facilitates cleaning of the screen holes, comprising a screen barrel, with limiting rings at both ends of the screen barrel, and a fixing plate fixedly mounted at the end of the limiting rings away from the screen barrel, the screen barrel being located within a mounting frame, and the fixing plate being mounted on the mounting frame via a rotating rod, the mounting frame being provided with a collection assembly, and the mounting frame being provided with a toggle cleaning mechanism, the toggle cleaning mechanism comprising mounting plates symmetrically arranged on the mounting frame, a connecting rod rotatably arranged between the two mounting plates, a plurality of toggle pieces arrayed on the connecting rod, and a first inclined surface provided at the two ends of the toggle pieces that contact the screen barrel, the connecting rod being driven by a driving assembly, and the mounting frame being provided with an elastic cleaning mechanism for cleaning the screen holes on the screen barrel.

[0006] Furthermore, the drive assembly includes a first rotating wheel sleeved on the outer surface of the connecting rod, a second rotating wheel rotatably mounted on the mounting plate, and the second rotating wheel is located below the first rotating wheel. The first rotating wheel and the second rotating wheel are connected by a belt drive, and one side of the second rotating wheel is connected to the motor output end.

[0007] Furthermore, the mounting bracket is provided with a placement rack, which is used to install the motor.

[0008] Furthermore, a limiting plate is provided at the end of the connecting rod located on one side of the first rotating wheel, and the diameter of the limiting plate is larger than that of the connecting rod.

[0009] Furthermore, the elastic cleaning mechanism includes multiple sets of sliding sleeves located above the mounting frame. A sliding rod is slidably provided inside the sliding sleeve, and a second inclined surface is provided at the end of the sliding rod facing the screen barrel. A spring is provided between the end of the sliding rod away from the second inclined surface and the inner wall of the sliding sleeve.

[0010] Furthermore, multiple sets of the sliding sleeves are mounted on the fixing frame, and the fixing frame is located on the mounting bracket.

[0011] Furthermore, the collection assembly includes a collection trough mounted on a mounting frame, and the collection trough is located below the sieve barrel.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this drum screen for clay blocks, which facilitates cleaning of the screen holes, is reasonable and has the following advantages:

[0013] (1) The rotary screen can not only drive the screen barrel to rotate by the toggle cleaning mechanism, but also reduce the risk of screen hole blockage, thereby greatly improving the screening efficiency of clay blocks. In the traditional screening process, clay blocks are very easy to stick or get stuck in the screen hole due to high humidity or particle size close to the screen hole diameter, resulting in a decrease in screening efficiency or even shutdown for cleaning. In this design, the toggle cleaning mechanism achieves dual functions through the dynamic cooperation between the first inclined surface and the screen hole. On the one hand, the rotation of the toggle pushes the screen barrel to rotate, ensuring uniform material distribution and promoting screening. On the other hand, its inclined surface design can apply lateral pressure to the inner wall of the screen hole during rotation, knocking down or crushing the stuck particles, thereby clearing the screen hole in real time. In addition, the motor-driven connecting rod drives the toggle with a stable speed, forming a continuous cleaning effect, avoiding the tediousness of manual intervention, and improving efficiency at the same time.

[0014] (2) The drum screen facilitates the cleaning of the screen holes through the elastic cleaning mechanism. The second inclined surface of the slide rod makes elastic contact with the screen barrel, which further enhances the anti-clogging effect. When the screen barrel rotates, the slide rod is dynamically inserted into the screen hole under the action of the spring. If a blockage is encountered, the elastic force of the spring will enhance the penetrating force of the slide rod, directly pushing out or breaking the blockage. This design is especially suitable for clay with high viscosity, because the buffering effect of the spring can avoid hard collision damage to the screen holes, while ensuring that the cleaning force is moderate. After the paddle is responsible for the pre-cleaning of large particles, the slide rod is used to finely handle stubborn blockages, thus forming a multi-layer anti-clogging system. The sliding sleeve and slide rod of the elastic cleaning mechanism adopt a separate design. The pre-tightening force of the spring can be adjusted according to the material characteristics. For clay with high viscosity, a spring with stronger elasticity can be replaced to enhance the cleaning force. Attached Figure Description

[0024] Example 1:

[0025] A drum screen for clay blocks that facilitates cleaning of the screen holes includes a screen barrel 100. Limiting rings 101 are provided at both ends of the screen barrel 100. A fixing plate 102 is fixedly provided at the end of the limiting rings 101 away from the screen barrel 100. The screen barrel 100 is located within a mounting frame 200, and the fixing plate 102 is mounted on the mounting frame 200 via a rotating rod 103. A collection assembly is provided on the mounting frame 200, and a toggle cleaning mechanism is provided on the mounting frame 200. The toggle cleaning mechanism includes mounting plates 300 symmetrically arranged on the mounting frame 200. A connecting rod 301 is rotatably arranged between the two mounting plates 300. Multiple paddles 302 are arrayed on the connecting rod 301, and first inclined surfaces 3020 are provided on both sides of the paddles 302 that contact the screen barrel 100. The connecting rod 301 is driven by a driving assembly. The mounting frame 200 is provided with an elastic cleaning mechanism for cleaning the screen holes on the screen barrel 100.

[0026] The drive assembly includes a first rotating wheel 303 sleeved on the outer surface of the connecting rod 301, a second rotating wheel 307 rotatably mounted on the mounting plate 300, and the second rotating wheel 307 is located below the first rotating wheel 303. The first rotating wheel 303 and the second rotating wheel 307 are connected by a belt 308. One side of the second rotating wheel 307 is connected to the output end of the motor 306.

[0027] The mounting bracket 200 is provided with a placement bracket 305, and the placement bracket 305 is used to install the motor 306.

[0028] The end of the connecting rod 301 located on one side of the first rotating wheel 303 is provided with a limiting plate 304, and the diameter of the limiting plate 304 is larger than that of the connecting rod 301.

[0029] The elastic cleaning mechanism includes multiple sets of sliding sleeves 401 located above the mounting frame 200. A sliding rod 402 is slidably provided inside the sliding sleeve 401, and a second inclined surface 4020 is provided at the end of the sliding rod 402 facing the screen barrel 100. A spring 403 is provided between the end of the sliding rod 402 away from the second inclined surface 402 and the inner wall of the sliding sleeve 401.

[0030] Multiple sets of the sliding sleeves 401 are mounted on the fixed frame 400, and the fixed frame 400 is located on the mounting frame 200.

[0031] The collection assembly includes a collection trough 201 mounted on a mounting frame 200, and the collection trough 201 is located below the sieve barrel 100.

[0032] Working Principle: During operation, clay blocks are first transported into the sieve barrel 100. Sieving begins by rotating the sieve barrel 100. During sieving, the clay blocks may become clogged due to high moisture content or the presence of numerous particles close to the sieve hole size, affecting sieving efficiency. Therefore, a combination of a prying cleaning mechanism and a flexible cleaning mechanism is used to prevent clogging and improve efficiency. Once the clay blocks are inside the sieve barrel 100, the motor 306 is started, driving the second rotating wheel 307 to rotate. The second rotating wheel 307, in conjunction with the belt 308, drives the first rotating wheel 303 to rotate, thereby driving the connecting rod 301 to rotate. Simultaneously, the connecting rod 301 rotates, causing the pry bar 302 to rotate. The pry bar 302 moves within the sieve holes of the sieve barrel 100, pushing the sieve barrel 100 to rotate. The pry bar 302 has a first inclined surface 3020 near both ends of the sieve barrel 100 for cleaning within the sieve holes. The screen barrel 100 is squeezed and driven to rotate. The first inclined surface 3020 is engaged with the screen hole, and the paddle 302 can push down the clay block stuck in the screen hole while prying it to prevent blockage. The paddle 302 drives the screen barrel 100 to rotate while cleaning the screen hole. The motor 306 here can be a servo motor. At this time, when the screen barrel 100 rotates, the screen barrel 100 is squeezed against the second inclined surface 4020. When it encounters the screen hole, the slide rod 402 is inserted into the screen hole under the action of the spring 403. When there is clay blockage in the screen hole, the slide rod 402 will clean it. The slide rod 402 is matched with the screen hole. The two cleaning mechanisms work together to facilitate the cleaning of the screen barrel 100 and prevent blockage, which would affect the screening efficiency. The preload of the spring 403 can be adjusted according to the material characteristics. For clay with high viscosity, a stronger spring 403 can be replaced to enhance the cleaning force.
