[0002] The double-roll sand making machine, also known as the twin-roll sand making machine, is a device widely used in the medium crushing and fine crushing of ores and rocks with medium hardness or below in industrial sectors such as sand making, ore dressing, cement, metallurgy, chemical industry, and building materials. The double-roll sand making machine mainly consists of roll wheels, a frame part, a pressing and adjusting device, a transmission device, etc. The driving device consists of two motors, which drive two roll wheels to rotate relatively by means of triangular belt transmission to the sheave wheels to crush the materials by rolling.

[0003] The existing power driving method of the active roll skin component of the double-roll sand making machine is that the motor and the reducer are connected by a coupling, and the reducer transmits power to the active roll skin component through a coupling. When in use, since the rolls are cylindrical, when the external stones enter the device and contact the rolls, the stones will bounce after being squeezed by the roll wheels, and the bouncing crushed stones will fall into the device interior and the roll transmission position, which is not conducive to the roll drive operation and is prone to jamming, resulting in the paralysis of the sand making machine and affecting the production speed of the sand making machine.

The bottom end of the inlet 2 is fixedly connected to a feeding cover 3. The bottom end of the feeding cover 3 is fixedly connected to an upper protective cover 5. A sand making structure 4 is fixedly arranged inside the main body 1. A filtering bottom cover 6 is fixed to the bottom of the sand making structure 4. One end of the filtering bottom cover 6 is connected to the sand discharge port 7 in a communicating way. The upper protective cover 5 is fixedly connected to the top of the sand making structure 4. A guiding sleeve 16 is embedded at the top end of the upper protective cover 5. An inner protective cover 12 is fixedly connected to the inner side of the upper protective cover 5. A pushing layer 15 is fixedly connected to the inner side of the inner protective cover 12.

[0026] As Figures 2-3 shown in the figure, the sand making structure 4 includes an installation frame 8, a roller body 9, a limit bearing 10, a driving gear 11, a connecting frame 13 and a side protective plate 14. The installation frame 8 is arranged longitudinally in a rectangular frame body with two groups. The roller body 9 is arranged horizontally as a whole and is distributed longitudinally with two groups. And both ends of the roller body 9 are simultaneously connected with shaft bodies in a matching way. The limit bearing 10 is movably sleeved with the shaft body and is fixedly embedded inside the installation frame 8 at the same time. And the driving gear 11 is fixedly sleeved with the shaft body connected to the outer end of the roller body 9 and is located outside the installation frame 8 at the same time. Through the roller body 9, the effect of crushing and extruding external sand and gravel is achieved. Through the cooperation of the limit bearing 10 and the installation frame 8, the effect of ensuring the stability of the roller body 9 during rotation is achieved. Through the driving gear 11, the effect of driving the roller body 9 is achieved.

[0027] As Figure 3 shown in the figure, the connecting frame 13 is arranged in a rectangular frame plate and is attached to the upper part of the inner side of the side protective plate 14. And the connecting frame 13 is simultaneously fixedly connected to the outer side of the upper section of the inner protective cover 12. And the side protective plate 14 is set as a rectangular rubber plate. Two arc-shaped grooves are opened at the front and rear sides of its bottom end. The arc-shaped grooves are simultaneously movably sleeved with the shaft bodies connected to the outer ends of the roller body 9. Through the side protective plate 14, the effect of shielding and protecting the sand and gravel during the processing from the side position is achieved, which can effectively prevent the sand and gravel from leaking out, and then the protective effect is achieved. At the same time, the side protective plate 14 is set as a rubber plate, which can effectively buffer the bounced sand and gravel. Through the connecting frame 13, the effect of installing and fixing the side protective plate 14 and the outer side of the inner protective cover 12 is achieved.

[0028] During the processing of external sand and gravel, it enters the positions of the two roller bodies 9. The two roller bodies 9 rotate under the cooperation of the corresponding two driving gears 11 to crush and extrude the sand and gravel. The side protective plate 14 can effectively block the bounced sand and gravel from the side position during this process.

[0029] As Figures 2-3As shown in the figure, the upper protective cover 5 is integrally arranged in a trapezoidal shape, and its two ends are fixedly connected to the top of the mounting frame 8. There are two groups of inner protective covers 12, which are vertically distributed on both longitudinal sides of the upper protective cover 5. At the same time, the inner protective cover 12 is located outside the roller body 9. The upper section of the inner protective cover 12 is horizontally arranged in a rectangle, while the bottom section is convexly curved outward and is inclined outward. The upper section of the inner protective cover 12 and the connecting frame 13 are integrally arranged in a rectangle. The material guiding sleeve 16 is arranged in a rectangle and is vertically embedded into it from the top of the upper protective cover 5. The bottom end of the material guiding sleeve 16 is open and is connected to the upper part of the inner protective cover 12.

Through the upper protective cover 5, the effect of blocking and protecting the sand and gravel during the processing from the upper position is achieved. Through the inner protective cover 12, the effect of blocking and protecting the sand and gravel during the processing at the front and back positions is achieved. Through the material pushing layer 15, the effect of cleaning the crushed sand and gravel on the roller body 9 is achieved.

[0031] External sand and gravel are sent to the roller body 9 through the material guiding sleeve 16. At this time, the upper section of the inner protective cover 12 cooperates with the connecting frame 13 to form a rectangle, which can effectively ensure the contact between the sand and gravel and the roller body 9. During the processing of the roller body 9 on it, the bottom sections of the upper protective cover 5 and the inner protective cover 12 can effectively block the bounced sand and gravel, realizing the protection effect. At the same time, during the processing of the roller body 9 on the sand and gravel, as the roller body 9 rotates, the material pushing layer 15 can clean the sand and gravel particles on the surface of the roller body 9.

[0032] Two groups of driving gears 11 provided at the outer ends of the two groups of roller bodies 9 are engaged with each other, and one of the driving gears 11 is connected to an external driving device through belt drive;

[0033] The working principle of the present utility model is as follows: During the use of this device, external sand and gravel are sent into the material guiding sleeve 16 through the feeding port 2 and the feeding cover 3. The roller body 9 rotates to process the sand and gravel. During the processing, the side protection plate 14, the inner protective cover 12, and the upper protective cover 5 can effectively prevent the external stone from bouncing when it enters the device and contacts the roller body 9. At the same time, during the rotation of the roller body 9, the material pushing layer 15 on the inner side of the inner protective cover 12 can clean the crushed sand and gravel on its surface.

[0034] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
