[0018] The embodiments of the technical scheme of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as understood by those skilled in the art to which the present application belongs; the terms used herein are only for the purpose of describing the specific embodiments of the present application, and are not intended to limit the present application; the terms "include" and "have" and any variations thereof in the specification and claims of the present application and the above description of drawings are intended to cover non-exclusive inclusion.

[0019] Specifically, refer to Figs. 1 to 3 , Fig. 1 The overall cross-sectional structure schematic diagram of the automatic sand making production line provided by the embodiments of the present application, Fig. 2 The local structure schematic diagram at the shell provided by the embodiments of the present application, Fig. 3A local structure diagram of a rotating shaft and a connection thereof is provided for an embodiment of the present application. An automatic sand production line 100 includes a screening box 110, a screw elevator 120, and a belt conveyor 130. The screening box 110 is used for screening quartz sand. Since the quartz sand has been crushed into small particles at the front end, but may still be caked during storage and transfer, the screening box 110 can screen out the caked quartz sand. The belt conveyor 130 is used for conveying the screened and lime-removed quartz sand to a subsequent production workshop. A shell 140 is arranged on the outer periphery of the belt conveyor 130. The shell 140 is arranged to collect the belt conveyor 130, on the one hand to avoid dust from being scattered in the air, and on the other hand to collect the quartz sand and the like falling along the belt conveyor 130. A second discharge port 111 is arranged at the bottom of the screening box 110. The second discharge port 111 penetrates the shell 140 and extends onto the belt conveyor 130. The quartz sand screened by the screening box 110 falls directly onto the belt conveyor 130 through the second discharge port 111 for transfer. The bottom wall of the shell 140 gradually slopes downward from the end away from the screw elevator 120 to the end close to the screw elevator 120 and is communicated with the bottom inlet 112 of the screw elevator 120. Since the bottom wall of the shell 140 is arranged to be inclined, the quartz sand falling along the belt conveyor 130 falls into the shell 140 and slides along the bottom wall of the shell 140 to the bottom inlet 112 of the elevator and is finally conveyed by the elevator to the screening box 110 again. A rotating shaft 150 is rotatably connected to the outside of the shell 140. The rotating shaft 150 is used to connect a knocking shaft 160. One end of the rotating shaft 150 is a smooth end to satisfy the knocking of the rotating shaft 150 by a lever 171. After the lever 171 knocks the rotating shaft 150, the rotating shaft 150 further drives the knocking shaft 160 to move and knock the upper layer of the belt conveyor 130. The middle part of the rotating shaft 150 is connected to the outer wall of the shell 140 by a tension spring 151. One end of the rotating shaft 150 is connected to the knocking shaft 160. An arc-shaped through slot 141 is arranged at the shell 140. The knocking shaft 160 extends to the inside of the shell 140 along the arc-shaped through slot 141 and is located between the two layers of the belt conveyor 130. During the rotation of the knocking shaft 160 around the hinge point of the rotating shaft 150, the knocking shaft 160 is lifted upward and knocks the upper layer of the belt, so that the top layer of the belt conveyor 130 vibrates, so that the stone powder and the quartz sand on the top of the belt conveyor 130 can be lifted upward, and then the subsequent dust suction assembly 180 can suck out the stone powder.The side of the rotating shaft 150 away from the knocking shaft 160 is connected with a disc part 170 through motor drive, the top end of the disc part 170 is provided with a push rod 171, in the process of the disc part 170 rotating driven by the motor, the push rod 171 at the top of the disc passes through the end of the rotating shaft 150 and drives the rotating shaft 150 to rotate, in the process of rotating, the rotating shaft 150 drives the knocking shaft 160 to knock the top belt of the belt conveyor 130, further, when rotating to a certain angle, the push rod 171 is away from the rotating shaft 150, at this time, the rotating shaft 150 will reset under the action of the tension spring 151, so as to realize the continuous knocking of the top belt of the belt conveyor 130 by reciprocating circulation. The top of the shell 140 is provided with a dust suction assembly 180, which is used to suck out the stone powder in the shell 140. Since the stone powder is lighter than the quartz sand, the wind power of the negative pressure fan 183 can effectively separate the stone powder from the quartz sand.

[0020] As can be seen from the above, in the embodiment of the present application, the shell 140 is arranged on the outer periphery of the belt conveyor 130, and the rotating shaft 150, the disc part 170, the push rod 171 and the knocking shaft 160 are arranged on the shell 140, which are matched with each other, on the one hand, in the process of the disc part 170 rotating driven by the motor, the push rod 171 will stretch the tension spring 151 and then vibrate the rotating shaft 150, and then the rotating shaft 150 drives the knocking shaft 160 to knock the top belt layer of the belt conveyor 130, so that the quartz sand and the stone powder can be lifted, which is convenient for the subsequent suction of the stone powder; on the other hand, the shell 140 can collect the quartz sand falling from the belt conveyor 130 during the knocking process of the knocking shaft 160 in the shell 140 and then send the quartz sand to the spiral elevator 120 again through the inclined bottom wall of the shell 140 for recycling. The present application has high automation, the operation of taking out the stone powder is better integrated with the original sand production line, the overall volume of the equipment is reduced, and the work efficiency can be effectively improved.

[0021] In some embodiments, the middle part of the screening box 110 is provided with a screen 113, one side of the screen 113 is connected with a first discharge port 114, and the first discharge port 114 is communicated with the middle part of the spiral elevator 120. In the embodiment of the present application, after the quartz sand falling into the screening box 110 is screened by the screen 113, the quartz sand agglomerated on the top of the screen 113 will slide down along the screen 113 and then fall into the spiral elevator 120 through the first discharge port 114, and in the process of being lifted by the spiral elevator 120 and falling from the spiral elevator 120 to the screening box 110, the agglomerated quartz sand will be dispersed by impact, and then when the particles are small enough, they can pass through the screen 113 and finally enter the top of the belt conveyor 130 for transfer.

[0022] In some embodiments, the dust suction assembly 180 includes a dust storage box 181 fixed on the top of the shell 140, one side of the dust storage box 181 is connected with a negative pressure fan 183 through a bag filter 182, and the other side of the dust storage box 181 is connected with a dust collecting hood 185 through a pipe 184, the dust collecting hood 185 is connected with the inner cavity of the shell 140. For the convenience of description, the application provides a specific setting mode of the dust suction assembly 180, specifically, in the working process, the negative pressure fan 183 generates negative pressure to suck the stone powder in the shell 140 into the dust storage box 181 through the dust collecting hood 185, further, the stone powder and air are separated at the bag filter 182, and the stone powder is stored in the dust storage box 181.

[0023] In some embodiments, the beating shaft 160 is sleeved with an anti-skid sleeve 161 through a bearing seat. In the application, when the beating shaft 160 is lifted upward and contacts the bottom wall of the belt conveyor 130, the anti-skid sleeve 161 will rotate with the friction of the belt conveyor 130, thereby converting the sliding friction between the beating shaft 160 and the belt conveyor 130 into rolling friction between the anti-skid sleeve 161 and the belt conveyor 130, thereby effectively reducing the friction.

[0024] In some embodiments, the outer periphery of the push rod 171 is rotatably sleeved with a wear-resistant sleeve 171a. In the application, the wear-resistant sleeve 171a is arranged to reduce the friction between the push rod 171 and the rotating shaft 150, thereby avoiding overheating due to long-time collision between the push rod 171 and the rotating shaft 150.

[0025] In some embodiments, the shell 140 is provided with a U-shaped support 190, both ends of the U-shaped support 190 are welded on the outer wall of the shell 140 through a stand, the middle part of the U-shaped support 190 is provided with a transmission motor 191, and the output shaft of the transmission motor 191 penetrates the U-shaped support 190 and is coaxially connected to the disc part 170. In the application, the U-shaped support 190 is arranged to stably fix the transmission motor 191 above the disc part 170, and the transmission motor 191 drives the disc part 170 to rotate.
