Therefore, the following specific embodiments and the accompanying drawings are only exemplary descriptions of the technical scheme of the present application, and should not be regarded as the whole or as a limitation or restriction on the technical scheme of the present application.

[0021] Please refer to Figures 1-4 , in order to solve the problem that a large amount of fine sand is mixed in the coarse material, which seriously affects the screening accuracy, and further affects the gradation accuracy and quality stability of the subsequent building materials, the following preferred technical scheme is provided:

[0022] A multi-section chute device, comprising a mounting frame 1, and a connecting plate body 2 and a first screening plate 3 arranged in order on one side of the mounting frame 1, a second screening plate 4 is mounted on the inner wall of the first screening plate 3, a first collecting box 5 is arranged at the lower end of the second screening plate 4, a second collecting box 6 is arranged on one side of the first collecting box 5, the second screening plate 4 is inclined, the highest part of the inclined second screening plate 4 is connected with the first screening plate 3, and the lowest part of the inclined second screening plate 4 is lapped on the second collecting box 6. After the material is screened by the second screening plate 4, the fine material passes through the screen hole and falls into the first collecting box 5 below, and the coarse material that fails to pass through the screen hole slides along the inclined surface of the second screening plate 4 to the second collecting box 6. The first collecting box 5 and the second collecting box 6 have the same composition structure, and the first collecting box 5 and the second collecting box 6 are symmetrically distributed about the center of the mounting frame 1.

[0023] The first collecting box 5 comprises a box body 51 and a receiving plate 52 arranged on the inner wall of the box body 51, the lower end of the receiving plate 52 is fixedly connected with a mounting plate 53, the lower end of the mounting plate 53 is fixedly connected with an inner connecting rod 54, the lower end of the inner connecting rod 54 is provided with an outer connecting rod 55, the inner connecting rod 54 and the outer connecting rod 55 are slidably connected with the inner wall, the lower end of the outer connecting rod 55 is fixedly connected with the inner bottom of the cavity of the box body 51, the outer wall of the inner connecting rod 54 is sleeved with a reset spring 56, the upper end of the reset spring 56 is fixedly connected with the mounting plate 53, the lower end of the reset spring 56 is fixedly connected with the upper wall of the outer connecting rod 55, the lower wall of the mounting plate 53 is axially connected with a first connecting plate 57, the lower end of the first connecting plate 57 is axially connected with a second connecting plate 58, the lower end of the second connecting plate 58 is axially connected with the inner bottom of the cavity of the box body 51, the included angle between the first connecting plate 57 and the second connecting plate 58 is fixedly connected with a rubber elastic block 59, the inner wall of the first collecting box 5 is provided with a sliding groove body 510, the inner wall of the sliding groove body 510 is slidably connected with a sliding block body 511, and the sliding block body 511 is fixedly connected with the receiving plate 52.

[0024] Specifically, the sand to be screened first enters the first screening plate 3 and is subjected to preliminary screening by the first screening plate 3, and then is subjected to screening by the second screening plate 4 in an inclined state. A large amount of sand starts to slide along the inclined surface of the second screening plate 4 under the action of its own gravity. In the sliding process, the sand is subjected to screening by the second screening plate 4. The materials with a size smaller than the screen hole can pass through the screen hole and fall downward, directly falling into the first collecting box 5 located below the second screening plate 4, thereby completing the collection of fine materials. The materials with a size larger than the screen hole cannot pass through the screen hole and continue to slide along the inclined surface of the second screening plate 4 until sliding to the lowest part of the inclination, where the second collecting box 6 is lapped, so that these coarse materials enter the second collecting box 6 by inertia, thereby completing the collection process of coarse materials. The whole working process is multi-section chute screening. By utilizing the gravity of the materials and the screening effect of the screening plate, efficient separation of materials with different particle sizes is realized, and the problem that a large amount of fine sand is mixed in coarse materials, seriously affecting the screening precision and further affecting the grading accuracy and quality stability of subsequent building materials is solved.

[0025] When the sand is collected in the first collecting box 5 and the second collecting box 6, the sand falls on the receiving plate 52. As the sand increases, the receiving plate 52 moves downward in the cavity of the box body 51 through cooperation of the sliding groove body 510 and the sliding block body 511, thereby driving the mounting plate 53 to press the inner connecting rod 54, thereby compressing the reset spring 56. At the same time, the first connecting plate 57 and the second connecting plate 58 also compress the rubber elastic block 59 under driving. When the sand is taken out by the worker, as the sand decreases, the receiving plate 52 moves upward through the reaction force of the reset spring 56 and the rubber elastic block 59, so that the sand is always located at the opening of the box body 51, thereby facilitating the taking of the sand.
