[0002] In the ore processing industry, efficient and precise crushing equipment has always been key to improving production efficiency and ensuring product quality. With the acceleration of global industrialization, the demand for various ores continues to rise, and the scale of ore mining continues to expand, which places higher demands on ore crushing processes.

[0003] According to a public disclosure of a multi-roll crusher for ore (publication number: CN221602090U), it includes a crusher body, a spraying assembly is provided at one end of the inner side of the crusher body, two sets of electromagnetic control valves are symmetrically arranged on the outer sides of both ends of the spraying assembly, and a diversion pipe is provided at the output end of the spraying assembly. Multiple atomizing nozzles are provided on the lower end face of the diversion pipe, and a slot is provided at the bottom of the other end of the crusher body, and a slide rail is arranged laterally at the bottom of the inner side of the crusher body.

[0004] In the aforementioned application, after the ore is crushed, large volumes of ore are still mixed into the crushed material, which affects sales and needs to be improved. Therefore, we propose a multi-roll crusher for ore. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a multi-roll crusher for ore, which solves the problem in the related technology that after the ore is crushed, there are still large volumes of ore mixed in with the crushed material, thus affecting the sale.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a multi-roll crusher for ore, including a conveying mechanism, a support plate provided at the top of the conveying mechanism, a feed hopper provided inside the support plate, a crushing component provided inside the feed hopper, and a vibrating screening mechanism provided at the bottom of the feed hopper.

[0007] The vibrating screening mechanism includes a motor, which is mounted on the side of a support plate. A rotating shaft is fixedly connected to the end of the motor's output shaft, and a transmission gear is fixedly connected to the circumferential surface of the rotating shaft. A sliding groove is formed on the inner side wall of the support plate, and a screening plate is slidably connected to the sliding groove. A rack is fixedly connected to the bottom of the screening plate, and a connecting spring is fixedly connected to the rear side of the screening plate. A fixing plate is fixedly connected to the end of the connecting spring away from the screening plate. The design of the fixing plate helps to make the connecting spring more stable during the extension and contraction process.

[0008] For example, in at least one embodiment of the present disclosure, a multi-roll crusher for ore is further provided, wherein a spill prevention plate is fixedly connected to the bottom of the screening plate, and the design of the spill prevention plate is beneficial to preventing the ore after screening from splashing.

[0009] The transmission gear is configured as a half gear, and the transmission gear meshes with the rack. This design is advantageous because when the transmission gear rotates, it drives the meshing rack to move.

[0010] The side section of the fixed plate is L-shaped, and the initial state of the connecting spring is set to a relaxed state. The design of the connecting spring is conducive to driving the screening plate to reset.

[0011] The side section of the support plate is concave, and this design helps to enhance the stability of the crushing assembly during operation.

[0012] According to another aspect, at least one embodiment of this disclosure also provides a multi-roll crusher for ore, including an anti-clogging mechanism disposed inside the screening plate. The anti-clogging mechanism includes a connecting plate, which is fixedly connected to the rear side of a fixed plate. A sliding rod extends through the rear side of the connecting plate. A push plate is fixedly connected to the circumferential surface of the sliding rod, and a scraper is fixedly connected to the bottom of the push plate. The above design is beneficial to prevent clogging of the screening plate.

[0013] For example, in at least one embodiment of the present disclosure, a multi-roll crusher for ore is further provided, which includes: a return spring fixedly connected to the circumferential surface of the sliding rod, and the end of the return spring away from the sliding rod is fixedly connected to the rear side of the connecting plate; a contact plate is fixedly connected to the circumferential surface of the sliding rod, and the design of the contact plate is beneficial to increasing the contact area with the connecting plate.

[0014] The side section of the connecting plate is set to be concave, and the connecting plate is located on the movement trajectory of the contact plate. The above design is beneficial to the sliding rod sliding when the contact plate contacts the connecting plate.

[0015] The scrapers are arranged in a linear array at the bottom of the push plate, and the scrapers are located in the filter holes of the screening plate. This design helps to prevent the filter holes of the screening plate from becoming clogged.

[0016] The initial state of the reset spring is set to a relaxed state. This design is beneficial because when the screening plate is reset, it will drive the sliding rod to reset.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] 1. In this disclosure, the driving force of the motor drives the rotating shaft, transmission gear, screening plate, rack, fixing plate, connecting spring, anti-spill plate, rack and other components to cooperate with each other, thereby starting the motor that runs through the side of the support plate, thereby driving the rotating shaft fixed at the end of the output shaft to rotate. The rotation of the rotating shaft drives the transmission gear fixed on the circumferential surface to rotate. The movement of the transmission gear causes the meshing rack to be pushed, thus preventing large volumes of incompletely crushed ore from being mixed into the crushed material after the ore crushing is completed.

[0019] 2. In this disclosure, the movement of the screening plate drives the connecting plate, sliding rod, push plate, scraper, return spring, contact plate and other components to work together. When the screening plate moves, it drives the sliding rod through the rear side to move. When the sliding rod moves to a certain position, the contact plate fixed on the circumferential surface contacts the inner wall of the connecting plate, thereby squeezing the sliding rod and preventing the screening plate from clogging when screening the crushed ore.

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5As shown, it illustrates a multi-roll crusher for ore in one embodiment of the present disclosure, including a conveying mechanism 1, a support plate 2 is provided on the top of the conveying mechanism 1, a feed hopper 3 is provided inside the support plate 2, a crushing component 4 is provided inside the feed hopper 3, and a vibrating screening mechanism 5 is provided at the bottom of the feed hopper 3.

[0034] The vibrating screening mechanism 5 includes a motor 51, which is located on the side of the support plate 2. The output shaft of the motor 51 is fixedly connected to a rotating shaft 52, and a transmission gear 53 is fixedly connected to the circumferential surface of the rotating shaft 52. A sliding groove 59 is provided on the inner side wall of the support plate 2, and a screening plate 54 is slidably connected to the sliding groove 59. A rack 55 is fixedly connected to the bottom of the screening plate 54, and a connecting spring 57 is fixedly connected to the rear side of the screening plate 54. A fixing plate 56 is fixedly connected to the end of the connecting spring 57 away from the screening plate 54. The design of the fixing plate 56 helps to make the connecting spring 57 more stable during the extension and contraction process.

[0035] In some examples, a spill prevention plate 58 is fixedly connected to the bottom of the screening plate 54. The design of the spill prevention plate 58 helps to prevent the ore from splashing after screening.

[0036] The transmission gear 53 is configured as a half gear, and the transmission gear 53 meshes with the rack 55. The above design is beneficial to drive the meshing rack 55 to move when the transmission gear 53 rotates.

[0037] The side section of the fixed plate 56 is set to L-shape, and the initial state of the connecting spring 57 is set to relaxed state. The design of the connecting spring 57 is conducive to driving the screen plate 54 to reset.

[0038] The side section of the support plate 2 is set to be concave, and the above design is conducive to enhancing the stability of the crushing component 4 during operation.

[0039] For example, such as Figures 1-5 As shown, after the ore is crushed, the crushed ore falls into the interior of the screening plate 54. At this time, the motor 51, which runs through the side of the support plate 2, is started, thereby driving the rotating shaft 52 fixed at the end of the output shaft to rotate. The rotation of the rotating shaft 52 drives the transmission gear 53 fixed on the circumferential surface to rotate. The movement of the transmission gear 53 causes the meshing rack 55 to be pushed, and at the same time, the screening plate 54, which slides on the inner wall of the chute 59, slides on the inner wall of the chute 59. When the screening plate 54 moves, it causes the connecting spring 57 fixed on the rear side to be in a taut state. Then, when the transmission gear 53 no longer meshes with the rack 55, the connecting spring 57 returns to its original position according to its own elasticity, thereby driving the screening plate 54 to return to its original position. When the transmission gear 53 rotates to a certain position, it meshes with the rack 55 again, thereby causing the screening plate 54 to perform reciprocating linear motion. By causing the screening plate 54 to vibrate, the crushed ore is screened, preventing large-volume ore that is not completely crushed from being mixed into the crushed ore.

[0040] like Figures 1-5 As shown, it illustrates a multi-roll crusher for ore in another embodiment of this disclosure, which is largely the same as the technical solution of embodiment 1. Therefore, only the differences are described in detail. The anti-clogging mechanism 6 is provided inside the screening plate 54. The anti-clogging mechanism 6 includes a connecting plate 61, which is fixedly connected to the rear side of the fixed plate 56. A sliding rod 62 passes through the rear side of the connecting plate 61. A push plate 63 is fixedly connected to the circumferential surface of the sliding rod 62. A scraper 64 is fixedly connected to the bottom of the push plate 63. The above design is beneficial to prevent the screening plate 54 from clogging.

[0041] In some examples, the slide rod 62 is also fixedly connected to a return spring 65 on its circumferential surface, and the end of the return spring 65 away from the slide rod 62 is fixedly connected to the rear side of the connecting plate 61. The slide rod 62 is fixedly connected to a contact plate 66 on its circumferential surface. The design of the contact plate 66 is conducive to increasing the contact area with the connecting plate 61.

[0042] The side section of the connecting plate 61 is set to be concave, and the connecting plate 61 is located on the movement trajectory of the contact plate 66. The above design is beneficial to the sliding rod 62 sliding when the contact plate 66 contacts the connecting plate 61.

[0043] Several scrapers 64 are arranged in a linear array at the bottom of the pusher plate 63. The scrapers 64 are located in the filter holes of the screening plate 54. The above design helps to prevent the filter holes of the screening plate 54 from becoming clogged.

[0044] The initial state of the return spring 65 is set to a relaxed state. This design is beneficial because when the screening plate 54 is reset, it will drive the sliding rod 62 to reset.

[0045] For example, such as Figures 1-5 As shown, when the screening plate 54 moves, it drives the sliding rod 62 that runs through the rear side to move. When the sliding rod 62 moves to a certain position, the contact plate 66 fixed on the circumferential surface contacts the inner wall of the connecting plate 61, thereby squeezing the sliding rod 62 and causing it to slide into the screening plate 54. At this time, the return spring 65 fixed on the circumferential surface of the sliding rod 62 is in a taut state. When the sliding rod 62 moves, it drives the push plate 63 fixed on the circumferential surface to move. The movement of the push plate 63 drives the scraper 64 fixed at the bottom to move, thereby scraping away the material blocked in the filter holes of the screening plate 54. At the same time, when the screening plate 54 resets, it drives the sliding rod 62 to reset. At this time, the return spring 65 resets according to its own elasticity, thereby driving the push plate 63 and the scraper 64 to reset.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications or substitutions should be covered within the scope of the claims of this disclosure.
