DETAILED DESCRIPTION
[0032] The following will be described in detail in combination with the accompanying drawings. Figures 1-4 The present application is further described in detail.
[0033] The present application discloses a self-cleaning chute. Referring to the drawings Figures 1 to 3 , including a support 1, a group of screening frames 4 are fixedly installed on the support 1, a plurality of carrier rollers 5 are rotatably arranged between the screening frames 4, and the carrier rollers 5 are arranged in parallel and inclined to each other. The end of the carrier roller 5 inclined upward is the feeding end 511, the end of the carrier roller 5 inclined downward is the waste end 512, and the gap between the carrier rollers 5 is the material falling gap 51. The lifting assembly 3 is installed on the support 1, the cleaning platform 2 is installed on the lifting assembly 3, and the lifting assembly 3 is used to drive the cleaning platform 2 to lift. The let go of the through slot 21 is provided through the cleaning platform 2, and the let go of the through slot 21 is provided for the screening frame 4 to be inserted. The cleaning tines 8 are arranged between adjacent carrier rollers 5, the cleaning tines 8 are jointly installed with the cleaning cross beam 81, and the cleaning cross beam 81 is slidably installed on the cleaning platform 2. When the chute is in a screening working condition, the lifting assembly 3 drives the cleaning platform 2 to rise, so that the cleaning tines 8 are separated from the carrier roller 5. When the material to be screened is placed on the carrier roller 5, the material meeting the particle size requirement falls from the material falling gap 51 between the carrier rollers 5, and the material not meeting the particle size requirement is intercepted on the carrier roller 5. Since the carrier roller 5 is arranged in an inclined manner, most of the material intercepted on the carrier roller 5 slides away from the carrier roller 5 along the inclined direction, thereby reducing the situation that the material is accumulated on the carrier roller 5 to block the gap of the carrier roller 5. When the chute is in a cleaning working condition, the lifting assembly 3 drives the cleaning platform 2 to descend, so that the cleaning tines 8 are inserted between adjacent carrier rollers 5, and the cleaning tines 8 are close to the feeding end 511 of the carrier roller 5. Then the cleaning cross beam 81 drives the cleaning tines 8 to move from the feeding end 511 of the carrier roller 5 to the waste end 512 of the carrier roller 5, so as to push the material not meeting the particle size requirement away from the carrier roller 5 from the waste end 512. After the cleaning tines 8 move to the waste end 512 of the carrier roller 5, the lifting assembly 3 drives the cleaning platform 2 to rise, so that the cleaning tines 8 are separated from the carrier roller 5, and then the cleaning cross beam 81 drives the cleaning tines 8 to reset above the feeding end 511 of the carrier roller 5. After the cleaning tines 8 are reset, if the material clamped on the carrier roller 5 is cleaned at this time, the chute is switched to the screening working condition; if the material clamped on the carrier roller 5 is not cleaned, the lifting assembly 3 drives the cleaning platform 2 to descend again to clean the material. This cycle is repeated until the material clamped on the carrier roller 5 is cleaned, thereby realizing the effect of facilitating the cleaning of the chute.
[0034] In order to achieve the effect of classifying and collecting unqualified material of qualified material box, referring to Figures 1 to 4 , a material collecting bin 52 is arranged below the material falling gap 51, and the material collecting bin 52 is installed on the support 1. When the material to be screened is placed on the carrier roller 5, the material meeting the particle size requirement falls from the material falling gap 51 between the carrier rollers 5 into the material collecting bin 52, achieving the effect of collecting qualified material. The material falling shaft 6 is coaxially arranged with the carrier roller 5. The distance between adjacent material falling shafts 6 is greater than the distance between adjacent carrier rollers 5, and the material falling gap 61 is formed between adjacent material falling shafts 6. A waste material bin 62 is arranged below the material falling gap 61, and the waste material bin 62 is installed on the support 1. During the movement of the cleaning rake 8 from the material inlet end 511 of the carrier roller 5 to the material outlet end 512 of the carrier roller 5, the cleaning rake 8 pushes the material on the carrier roller 5 onto the material falling shaft 6. Since the width of the material falling gap 61 is greater than the particle size of the unqualified material, the unqualified material falls from the material falling gap 61 between the material falling shafts 6 into the waste material bin 62, achieving the effect of collecting unqualified material.
[0035] In order to achieve the effect of moving the cleaning rake 8 along the gap between the carrier rollers 5, referring to Figure 1 and Figure 2 , a cleaning piston cylinder 7 is installed on the cleaning platform 2, and the output shaft of the cleaning piston cylinder 7 is welded to the cleaning cross beam 81. A set of guide rails 71 is installed on the top of the cleaning platform 2, and the guide rails 71 are parallel to each other. A guide block 72 is slidably arranged on the guide rail 71, and the guide block 72 is welded to the cleaning cross beam 81. A set of limiting blocks 73 is installed on the guide rail 71, and the cleaning cross beam 81 is located between the limiting blocks 73. The output shaft of the cleaning piston cylinder 7 drives the cleaning cross beam 81 to move along the guide rail 71, and since the guide rails 71 are parallel to each other, the cleaning rake 8 moves along the gap between the carrier rollers 5. During the movement of the cleaning cross beam 81 along the guide rail 71, the limiting blocks 73 limit the movement range of the cleaning cross beam 81, reducing the impact of the cleaning rake 8 on the bearing seat of the carrier roller 5.
[0036] In order to achieve the effect of lifting the cleaning platform 2 relative to the screening frame 4, referring to Figure 1The lifting assembly 3 comprises a plurality of lifting piston cylinders 31 and a plurality of guide rods 32. The lifting piston cylinders 31 are installed on the support 1, and the output shafts of the lifting piston cylinders 31 are welded with the cleaning platform 2. The top ends of the guide rods 32 are welded with the cleaning platform 2, the guide rods 32 are sleeved with guide plates 33, and the guide plates 33 are welded with the support 1. The output shafts of the lifting piston cylinders 31 drive the cleaning platform 2 to move, so that the cleaning platform 2 is lifted relative to the screening frame 4. During the movement of the cleaning platform 2, the guide rods 32 move along the guide plates 33, so that the stability of the lifting of the cleaning platform 2 is improved.
[0037] The implementation principle of the embodiment of the application is as follows: when the roller screen is in the screening working condition, the cleaning platform 2 is lifted, so that the cleaning tines 8 are separated from the carrier rollers 5. When the materials to be screened are placed on the carrier rollers 5, the materials meeting the particle size requirement fall into the material collecting bin 52 through the material falling gaps 51 between the carrier rollers 5, and the materials not meeting the particle size requirement are intercepted on the carrier rollers 5. Since the carrier rollers 5 are arranged in an inclined manner, most of the materials intercepted on the carrier rollers 5 slide along the inclined direction of the carrier rollers 5 and fall into the waste material bin 62. When the roller screen is in the cleaning working condition, the lifting assembly 3 drives the cleaning platform 2 to descend, so that the cleaning tines 8 are inserted between the adjacent carrier rollers 5, and the cleaning tines 8 are close to the material feeding end 511 of the carrier rollers 5. Then the cleaning cross beams 81 drive the cleaning tines 8 to move from the material feeding end 511 of the carrier rollers 5 to the waste material end 512 of the carrier rollers 5, so that the materials not meeting the particle size requirement are pushed to fall into the waste material bin 62 from the waste material end 512. After the cleaning tines 8 move to the waste material end 512 of the carrier rollers 5, the cleaning platform 2 is lifted, so that the cleaning tines 8 are separated from the carrier rollers 5, and then the cleaning cross beams 81 drive the cleaning tines 8 to reset above the material feeding end 511 of the carrier rollers 5. After the cleaning tines 8 are reset, if the materials clamped on the carrier rollers 5 are cleaned at this time, the roller screen is switched to the screening working condition; if the materials clamped on the carrier rollers 5 are not cleaned, the lifting assembly 3 drives the cleaning platform 2 to descend again to clean the materials. The above process is repeated until the materials clamped on the carrier rollers 5 are cleaned, so that the effect of facilitating the cleaning of the roller screen is achieved.
[0038] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape and principle of the application should be covered within the protection scope of the application.
