[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] The following is combined with Figure 1-5 This invention describes a novel sand making machine, comprising:

[0034] Support frame 1 has a support platform at the top and a hollow structure in the middle;

[0035] The cover cylinder 2 is fixedly connected to the top of the support frame 1. A grinding ring 22 is fixedly provided inside the cover cylinder 2. The grinding ring 22 is fixedly connected to the cover cylinder 2. The cover cylinder 2 is fixedly installed on the support platform formed on the top of the support frame 1.

[0036] The sand-making mechanism 3 is installed inside the grinding ring 22. It includes a feeding component 31 and a grinding roller component 32 that are synchronously rotatably connected inside the grinding ring 22. The feeding component 31 is used to feed materials into the grinding ring 22 in sections. The grinding roller component 32 includes a grinding roller body 324. A grinding gap is formed between the grinding roller body 324 and the grinding ring 22. Sand and gravel are fed from the top of the cover cylinder 2 and conveyed to the grinding gap formed inside the cover cylinder 2 through the feeding component 31. By rotating the grinding roller body 324, the sand and gravel are placed in the grinding gap for grinding, thereby achieving the crushing and extrusion of the sand and gravel to obtain sand and gravel of the required mesh size. The feeding component 31 can be used to feed the sand and gravel in sections, directly and evenly conveying the sand and gravel to each grinding gap for the first grinding. This ensures uniform grinding of the sand and gravel and achieves equal wear of multiple grinding roller bodies 324, avoiding wear on the grinding roller components. 32 Due to uneven wear and stress, the rotating grinding roller 32 rotates eccentrically. A guide shovel groove 327 is provided on one side of the grinding roller body 324. The guide shovel groove 327 is used to guide the material in the cover cylinder 2 into the grinding gap. The bottom of the cover cylinder 2 is connected to a discharge chute 332. The guide shovel groove 327 rotates synchronously at the bottom of the cover cylinder 2. When the material falls into the bottom of the cover cylinder 2, since the guide shovel groove 327 is installed at an angle upward, when the guide shovel groove 327 rotates at the bottom of the cover cylinder 2, the guide shovel groove 327 can guide and shovel up the material at the bottom of the cover cylinder 2. At the same time, since the two ends of the guide shovel groove 327 are open and the upper end is located on the side of the grinding interval, the guide shovel groove 327 realizes the transportation of the material at the bottom of the cover cylinder 2 to the grinding gap for secondary grinding under the continuous shoveling action, thereby improving the grinding quality and performing secondary grinding on the sand and gravel that was not thoroughly ground in the first grinding.

[0037] The power mechanism 4 is fixedly installed on the support frame 1 and is used to drive the grinding roller 32 to rotate. The power mechanism 4 drives the grinding roller body 324 to rotate, so that a grinding gap is formed between it and the grinding ring 22.

[0038] Please refer to Figures 2-3 As shown, the feeding component 31 includes:

[0039] The collecting cylinder 311 is open at the top, with multiple rectangular grooves 312 extending through its bottom. These rectangular grooves 312 are arranged in a circular array along the collecting cylinder 311. A baffle plate 313 is fixedly attached to one end of each rectangular groove 312. During sand and gravel processing, sand and gravel are fed into the collecting cylinder 311, flowing downwards through the multiple rectangular grooves 312. Each rectangular groove 312 corresponds to a specific grinding gap for feeding. A baffle plate 313 is fixedly attached to one end of each rectangular groove 312. Because... The collecting cylinder 311 and the grinding roller 32 rotate synchronously inside the cover cylinder 2. When the collecting cylinder 311 is loaded with material and rotates, the material will rotate with the inner wall of the collecting cylinder 311, which will affect the normal discharge of sand and gravel through the rectangular groove 312. At the same time, the sand and gravel will be biased towards one of the rectangular grooves 312 for a large amount of discharge, resulting in intermittent grinding overload of the corresponding roller. By fixing a baffle plate at one end of the rectangular groove 312, the sand and gravel can be blocked to prevent the sand and gravel from rotating with the collecting cylinder 311. At the same time, it can ensure that each rectangular groove 312 conveys sand and gravel downwards equally.

[0040] The discharge pipe 314 is connected to the inside of the collecting cylinder 311 through the rectangular groove 312 at one end. The discharge pipe 314 is connected to the rectangular groove 312 to discharge the sand and gravel in the collecting cylinder 311.

[0041] The diversion conveying pipe 315 is connected at one end to the discharge pipe 314 and at the other end to the guide shovel groove 327. The diversion conveying pipe 315 receives the discharge pipe 314 and the guide shovel groove 327 respectively. Under the action of its rotation, the guide shovel groove 327 shovels up the material at the bottom of the cover cylinder 2 to help push the sand and gravel to participate in the first tumbling.

[0042] Please refer to Figures 3-4 As shown, the grinding roller component 32 further includes:

[0043] The central shaft 321 is rotatably connected to the center of the cover cylinder 2 and is driven by the power mechanism 4. Its middle part passes through the bottom of the cover cylinder 2 and is rotatably connected to the cover cylinder 2.

[0044] A plum blossom plate 322 is fixedly connected to the top of the central shaft 321 at its center. An installation notch 323 is formed on the plum blossom plate 322. The grinding roller body 324 is installed in the installation notch 323. The two ends of the discharge pipe 314 are fixedly connected to the plum blossom plate 322 and the collection cylinder 311, respectively. The plum blossom plate 322 serves as the main body for installing the grinding roller body 324 and the collection cylinder 311, enabling the feeding component 31 and the grinding roller component 32 to be rotatably connected in the cover cylinder 2. In this application, the grinding roller body 324 is installed on the plum blossom plate 322 at a certain angle. The distance between the bottom of the grinding roller body 324 and the grinding ring 22 is greater than the distance between the top of the grinding roller body 324 and the grinding ring 22, which can increase the amount of sand and gravel input in the grinding gap. By gradually lowering the grinding gap from the bottom to the top, the intake is increased while ensuring that the sand and gravel are ground to the required mesh size.

[0045] The grinding roller body 324 is provided in multiple ways. The multiple grinding roller bodies 324 are arranged in a ring array with the central axis 321 as the center point. Each grinding roller body 324 corresponds to a diversion conveying pipe 315 to perform zoned grinding of the sand and gravel conveyed by the feed component 31, so as to improve the uniformity of sand and gravel grinding.

[0046] Please refer to Figure 5 As shown, the bottom of the cover cylinder 2 includes a positioning plate 325 and a rotating plate 326. The positioning plate 325 is fixedly connected to the cover cylinder 2, and the rotating plate 326 rotates within the positioning plate 325. The guide shovel groove 327 is fixedly installed on the rotating plate 326 via a mounting base. The bottom of the cover cylinder 2 is composed of the positioning plate 325 and the rotating plate 326. The positioning plate 325 is fixedly installed on the support frame 1, while the rotating plate 326 rotates within the positioning plate 325. The guide shovel groove 327 is fixedly installed on the rotating plate 326. By rotating the guide shovel groove 327, the sand and gravel on the positioning plate 325 can be shoveled up and conveyed to one end of the guide shovel groove 327 into the tumbling gap for secondary tumbling. The bottom of the guide shovel groove 327 is close to the upper surface of the positioning plate 325, and its width matches that of the positioning plate 325.

[0047] Please refer to Figure 5 As shown, the guide shovel groove 327 is installed at the same height on the rotating plate 326 at one end and the same height on the rotating plate 326 at the same height. This allows the sand and gravel on the positioning plate 325 to be shoveled up at an angle and pushed into the tumbling gap for secondary tumbling.

[0048] Please refer to Figure 3 , Figure 5As shown, the sand making mechanism 3 also includes a discharge component 33, which includes a discharge notch 331. The discharge notch 331 is formed on the positioning plate 325. The bottom of the discharge notch 331 is connected to a discharge trough 332. A limiting notch is connected to the discharge trough 332. When the guide shovel 327 rotates, a discharge time difference is formed between the two guide shovel 327s. When the guide shovel 327 passes above the discharge notch 331, the guide shovel 327 will block a large amount of sand and gravel from being discharged through the discharge notch 331. When the sand and gravel after tumbling are discharged, the guide shovel 327 rotates to push the sand and gravel circumferentially along the inner wall of the cover cylinder 2. When pushed to the discharge notch 331, the sand and gravel fall down along the discharge notch 331 and are finally output through the discharge trough 332.

[0049] Please refer to Figure 1 As shown, the power mechanism 4 includes a drive motor 41, which is fixedly mounted on the bottom of the support frame 1 via a motor mounting base 42. The output end of the drive motor 41 drives the grinding roller 32 to rotate via a belt. The drive motor 41 is used to drive the central shaft 321 to rotate. The rotation of the central shaft 321 will drive the plum blossom plate 322, grinding roller body 324, collection cylinder 311, and rotating plate 326 fixedly connected thereon to rotate synchronously.

[0050] Please refer to Figure 1 As shown, the cover cylinder 2 is provided with an inspection port 21. The inspection port 21 is connected to the circumference of the cover cylinder 2 and can be opened / closed. The inspection port 21 can be used for internal maintenance of the cover cylinder 2 and cleaning of internal sand and gravel.

[0051] Working principle of this utility model:

[0052] Sand and gravel are added from the collection cylinder 311. After addition, the material is blocked by the baffle plate and the sand and gravel are fed downward through multiple rectangular grooves 312 opened at the bottom. The sand and gravel are then conveyed into the cover cylinder 2 through the rectangular grooves 312, the discharge pipe 314 and the diversion conveying pipe 315 in sequence. Since the bottom of the diversion conveying pipe 315 is located directly above the guide shovel groove 327, the sand and gravel are finally conveyed into the guide shovel groove 327.

[0053] The bottom of the cover cylinder 2 is composed of a positioning plate 325 and a rotating plate 326. The guide shovel groove 327 is fixedly installed on the rotating plate 326 by a mounting seat. The rotating plate 326 and the guide shovel groove 327 are rotatably connected inside the cover cylinder 2 under the driving action of the drive motor 41. Since the installation height of the guide shovel groove 327 on the rotating plate 326 is higher at one end than at the other end, the guide shovel groove 327 conveys the sand and gravel inside to the grinding gap formed between the grinding ring 22 and the grinding roller body 324 under its rotation.

[0054] The drive motor 41 synchronously drives the plum blossom plate 322 to rotate. The grinding roller body 324 is fixedly installed on the plum blossom plate 322. Therefore, the rotation of the grinding roller body 324 can perform the first rolling and squeezing of the sand and gravel conveyed to the rolling gap, thereby crushing the sand and gravel. After the sand and gravel are crushed, they fall into the next guide shovel groove 327. Under the action of the guide shovel groove 327, the sand and gravel on the positioning plate 325 can be shoveled up and pushed into the grinding roller body 324 for secondary rolling.

[0055] As the rotating plate 326 rotates, the guide shovel 327 pushes the sand and gravel along the inside of the cover cylinder 2. Since a discharge notch 331 is provided on the positioning plate 325, the rotation of the guide shovel 327 can push the sand and gravel on the positioning plate 325. When the sand and gravel are pushed to the discharge notch 331, the sand and gravel fall down along the discharge notch 331 and are discharged from the equipment through the discharge chute 332, realizing the grinding of the sand and gravel to obtain the required mesh size.

[0056] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0057] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
