[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] For examples, please refer to Figure 1-3 This utility model provides a technical solution:
[0027] A stone crushing, screening, and conveying device includes a crushing box 1 and a screening box 2 located at the bottom of the crushing box 1. Crushing rollers 3 are arranged alternately and rotate inside the crushing box 1. A gear 301 is fixedly installed at the left end of the crushing roller 3, and a crushing motor 4 is fixedly installed at the right end of the crushing box 1. A screening plate 5 and a first electric conveyor belt 6 are arranged inside the screening box 2. A sliding rod 501 is installed on the top of the screening plate 5. An anti-detachment ring 502 is installed at the top of the sliding rod 501. A spring 503 is sleeved on the bottom outer side of the sliding rod 501. Vibration motors 504 are fixedly installed on both the front and rear sides of the bottom of the screening plate 5. A cleaning mechanism 7 is installed above the screening plate 5. A second electric conveyor belt 8 is installed on the top of the first electric conveyor belt 6.
[0028] Specifically, the left end of the crushing roller 3 extends to the left side of the crushing box 1, the output end of the crushing motor 4 passes through the right side surface of the crushing box 1 and is fixedly in contact with the right end of the crushing roller 3, the bottom inner wall of the crushing box 1 extends into the interior of the screening box 2, and the gears 301 mesh and drive each other.
[0029] In this embodiment, the crushing motor 4 is mainly used to drive the crushing roller 3. Under the meshing transmission of the gear 301, the crushing roller 3 rotates in opposite directions, thereby achieving the effect of shearing and squeezing the stone and meeting the crushing requirements of the stone.
[0030] Specifically, the screening plate 5 is inclined and its inner wall does not contact the inner wall of the screening box 2. The slide rod 501 is symmetrically distributed about the top surface of the screening plate 5. The bottom end of the slide rod 501 fits through the top surface of the screening plate 5 and is fixed to the inner wall of the screening box 2 by a fastener. The top end of the spring 503 contacts the bottom of the screening plate 5.
[0031] In this embodiment, the screening plate 5 is set to screen the crushed stone. The tilt angle of the screening plate 5, in conjunction with the vibration motor 504, causes the stone to roll in layers on the screening plate 5 under the action of gravity and vibration. The combination of the slide rod 501 and the spring 503 can provide elastic support for the screening plate 5, realizing stable vibration of the screening plate 5, which facilitates the passage of crushed material through the screen holes and improves the screening effect of the device.
[0032] Specifically, the second electric conveyor belt 8 is located on the bottom left side of the screening plate 5;
[0033] In this implementation plan, the displacement and conveying of crushed stone can be achieved by setting up the No. 2 electric conveyor belt 8 and the No. 1 electric conveyor belt 6.
[0034] It should be noted that the crushing motor 4, vibrating motor 504, electric conveyor belt 6, electric conveyor belt 8, electric slide rail 701, electric push rod 703 and variable speed motor 706 are electrically connected to the controller through wires.
[0035] In this embodiment, please refer to Figure 1 and Figure 3 The cleaning mechanism 7 includes an electric slide rail 701, which is fixedly installed on the top of the inner wall of the screening box 2. An electric slider 702 is slidably arranged on the inner wall of the electric slide rail 701. An electric push rod 703 is fixedly installed at the bottom of the electric slider 702. A mounting frame 704 is fixedly arranged at the telescopic end of the electric push rod 703. A cleaning brush 705 is rotatably arranged inside the mounting frame 704. A variable speed motor 706 is fixedly arranged on the front side of the mounting frame 704.
[0036] Specifically, the electric slide rail 701 is electrically connected to the electric slider 702. The electric slide rail 701 is distributed at equal intervals in front and back on the top inner wall of the screening box 2. The cleaning brush 705 is cylindrical in shape. The bottom surface of the cleaning brush 705 is lower than the bottom surface of the mounting frame 704. The output end of the variable speed motor 706 passes through the front end of the mounting frame 704 and is fixedly connected to the front side of the cleaning brush 705. The outer surface of the variable speed motor 706 does not contact the anti-detachment ring 502.
[0037] In this embodiment, the electric slider 702 and the electric slide rail 701 are mainly used to move the mounting frame 704 left and right, while the electric push rod 703 is mainly used to drive the mounting frame 704 to come close to the screening plate 5, so that the cleaning area of the cleaning brush 705 can cover the screening plate 5. The variable speed motor 706 is mainly used to drive the cleaning brush 705 to rotate, so that the cleaning brush 705 scrapes the top surface of the screening plate 5, thereby improving the cleaning efficiency of the screening plate 5.
[0038] The working process of this utility model is as follows: When using a stone crushing, screening, and conveying device, the stone is placed into the crushing box 1, and the crushing motor 4 is started. The output end of the crushing motor 4 drives the crushing roller 3 to rotate, while the gears 301 begin to mesh and rotate, causing the crushing roller 3 to rotate in opposite directions and crush the stone. The crushed stone then enters the screening box 2 and comes into contact with the screening plate 5. Then, the vibrating motor 504 is started, and the vibrating motor 504 generates a vibration force on the screening plate 5. The screening plate 5 then vibrates up and down along the outer surface of the slide rod 501, thereby facilitating the passage of the crushed material through the screen holes of the screening plate 5 and falling into the No. 1 electric conveyor located inside the screening box 2. The material that does not pass through the screening plate 5 falls onto the second electric conveyor belt 8 along the inclined surface of the screening plate 5. Finally, the material is conveyed by the first electric conveyor belt 6 and the second electric conveyor belt 8. When the screening plate 5 needs to be cleaned, the installation frame 704 and the cleaning brush 705 can move laterally through the cooperation of the electric slide rail 701 and the electric slider 702. With the setting of the electric push rod 703, the installation frame 704 and the cleaning brush 705 can move vertically, so that the cleaning brush 705 contacts the inclined surface of the screening plate 5. Driven by the variable speed motor 706, the cleaning brush 705 rotates and cleans the surface of the screening plate 5, which meets the needs of the user.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
