Description

Technical Field

[0001] This utility model belongs to the field of screening machine technology, and in particular relates to a clog-proof crushing cylindrical screening machine. Background Technology

[0002] A screening machine is a mechanical device that uses the relative movement between granular materials and the screen surface to allow some particles to pass through the screen holes, separating the materials into different grades according to particle size. Screening machines can pick out materials that do not meet the volume requirements, thus avoiding affecting subsequent processing and handling.

[0003] Chinese utility model patent CN219377375U discloses a crushing cylindrical screen with horizontally arranged scrapers equipped with bristles. The scrapers are in contact with the outer wall of the screen cylinder, and symmetrically arranged positioning rods corresponding to positioning grooves are located on the side of the scrapers away from the screen cylinder. The positioning rods pass through the positioning grooves and are connected to limiting blocks. By utilizing the contact between the scrapers and the screen cylinder, the screen cylinder is cleaned, making it very convenient to use and improving the screening effect. However, this crushing cylindrical screen has some defects and shortcomings in its use: firstly, its crushing force on materials is relatively weak, resulting in incomplete crushing when screening some harder materials, and it is prone to feed blockage. Moreover, it cannot perform graded screening. Therefore, there is an urgent need to improve the existing crushing cylindrical screen and provide a blockage-resistant crushing cylindrical screen. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a reasonably designed, simple, graded screening, and anti-clogging crushing cylindrical screening machine with crushing function, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clog-resistant crushing cylindrical screening machine includes a horizontally placed screen cylinder. A feed pipe is fixedly installed at the right end of the screen cylinder. A feed hopper is fixedly connected above the end of the feed pipe away from the screen cylinder. A crushing anti-clogging component is installed at the discharge port of the feed hopper. The crushing anti-clogging component includes a first motor, which is fixedly installed on the outer wall of the bottom front of the feed hopper. A horizontal shaft is installed on the inner bearing of the bottom of the feed hopper. The front end of the horizontal shaft is fixedly connected to the output end of the first motor. Multiple moving blades are fixedly sleeved at equal intervals along the length of the horizontal shaft. Multiple fixed blades are fixedly fixed at equal intervals on the inner walls of the left and right sides of the bottom of the feed hopper. The moving blades and fixed blades cooperate to form a shearing structure. A second motor is fixedly installed on the outer wall of the top of the left end of the screen cylinder. A gear is fixedly connected to the output end of the second motor. A screening component is installed on the inner side of the screen cylinder and is connected to the gear transmission. A third discharge hopper, a second discharge hopper, and a first discharge hopper are fixedly installed from left to right at the bottom of the screen cylinder.

[0007] Preferably, multiple moving tools and multiple stationary tools are arranged in an alternating manner.

[0008] Preferably, the screening assembly includes a screening cylinder, a pusher screw, and a gear ring. Both ends of the screening cylinder are connected to the screen cylinder bearing. The pusher screw is fixedly installed on the inner wall of the screening cylinder. The length of the pusher screw is equal to the length of the screening cylinder. A gear ring is fixedly sleeved on the outer side of the left end of the screening cylinder, and the gear ring meshes with a gear.

[0009] Preferably, the screening cylinder includes solid parts located at its left and right ends and a screen part located at its center, the screen part being divided into a second screening part and a first screening part.

[0010] Preferably, the first screening section is located to the right of the second screening section, and the internal aperture of the second screening section is larger than that of the first screening section.

[0011] Preferably, the second screening section corresponds to the second discharge hopper, and the first screening section corresponds to the first discharge hopper.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, during the process of feeding the material into the screening cylinder through the feeding hopper and feeding pipe, the first motor can be turned on to control the horizontal shaft to drive multiple moving blades to rotate rapidly. With the cooperation of multiple fixed blades on the inner wall of the bottom of the feeding hopper, the material is easily sheared and crushed, resulting in a better and more thorough crushing effect. Moreover, it can avoid the problem of blockage caused by large-volume materials.

[0014] This invention controls the rotation of the gear by starting the second motor, which drives the gear ring to rotate the screening cylinder at a constant speed inside the screening cylinder. The pusher screw fixed on the inner wall of the screening cylinder can slowly push the material from right to left, and make the material pass through the first screening section and the second screening section in sequence for screening. The final material can fall into the third discharge hopper through the left end of the screening cylinder. Since there is a difference in the aperture of the first screening section and the second screening section, it is easy to achieve the purpose of grading and screening the material, and the screening efficiency is higher.

A gear 6 is fixedly connected to the output end of the second motor 5. A screening component 7 is installed on the inner side of the screen cylinder 1. The screening component 7 is connected to the gear 6 for transmission. A third discharge hopper 8, a second discharge hopper 9, and a first discharge hopper 10 are fixedly installed from left to right at the bottom end of the screen cylinder 1.

[0025] As a preferred embodiment, based on the above structure, the crushing and anti-blocking component 4 further includes a first motor 41, a horizontal shaft 42, moving blades 43, and fixed blades 44. The first motor 41 is fixedly installed on the outer wall of the bottom front of the feed hopper 3. The horizontal shaft 42 is installed on the inner bearing of the bottom of the feed hopper 3. The front end of the horizontal shaft 42 is fixedly connected to the output end of the first motor 41. Multiple moving blades 43 are fixedly sleeved at equal intervals along the length direction of the outer side of the horizontal shaft 42. Multiple fixed blades 44 are fixedly fixed at equal intervals on the inner walls of the left and right sides of the bottom of the feed hopper 3.

[0026] In a preferred embodiment, based on the above structure, a plurality of moving blades 43 and a plurality of fixed blades 44 cooperate with each other to form a shearing structure, and the plurality of moving blades 43 and a plurality of fixed blades 44 are arranged at intervals.

[0027] In this embodiment, the first motor 41 can control the horizontal shaft 42 and the moving blade 43 to rotate rapidly, and with the cooperation of the fixed blade 44, the input material can be effectively crushed, thereby avoiding blockage.

[0028] In a preferred embodiment, based on the above structure, the screening assembly 7 further includes a screening cylinder 71, a pushing screw 72, and a gear ring 73. Both the left and right ends of the screening cylinder 71 are connected to the bearings of the screening cylinder 1. The pushing screw 72 is fixedly installed on the inner wall of the screening cylinder 71. The length of the pushing screw 72 is equal to the length of the screening cylinder 71. The gear ring 73 is fixedly sleeved on the outer side of the left end of the screening cylinder 71. The gear ring 73 meshes with the gear 6.

[0029] In this embodiment, when the second motor 5 is started to control the rotation of the gear 6, the gear ring 73 that meshes with the gear 6 can drive the screening cylinder 71 to rotate at a uniform speed, thereby facilitating the rolling screening of materials.

[0030] As a preferred embodiment, based on the above structure, the screening cylinder 71 further includes a solid part located at its left and right ends and a screen part located at its center. The screen part is divided into a second screening part 74 and a first screening part 75.

With the cooperation of the fixed blade 44, the material can be crushed quickly and efficiently, avoiding the problem of blockage caused by large-volume materials. The crushed material can be sent into the right end of the screening cylinder 71 through the inclined feed pipe 2.

[0035] The second motor 5 is started to control the gear 6 to rotate, and the gear ring 73 that meshes with the gear 6 can drive the screening cylinder 71 to rotate at a uniform and stable speed inside the screening cylinder 1. The material is then slowly pushed from right to left by the pusher screw 72 fixed on the inner wall of the screening cylinder 71. During the material pushing process, the material can be screened in sequence through the first screening section 75 and the second screening section 74, and discharged through the first discharge hopper 10 and the second discharge hopper 9 respectively. The last material can fall into the third discharge hopper 8 through the left end of the screening cylinder 71. Moreover, since there is a difference in the aperture of the first screening section 75 and the second screening section 74, it is convenient to classify and screen the material, and the screening efficiency is higher.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
