Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a sand and stone drying, grading and screening device. Background Art

[0002] Nowadays, China's modern architecture has broken through the limitations of modern times in terms of quantity, scale, type, regional distribution and modernization level, showing a brand new look. Sand and stone are essential raw materials in construction. Most of the construction sand and stone are medium and fine components of high-hard and extra-hard materials such as glass raw materials. However, since sand and stone usually need to be crushed after screening to avoid large pieces of sand and stone occupying the area, the sand and stone drying and grading screening device in the existing technology does not have a crushing function.

[0003] After searching, a construction sand and gravel grading and screening device (publication number CN208758031U) is now disclosed. This construction sand and gravel grading and screening device uses a spiral roller to drive the sand and gravel to be continuously transported upward, which solves the labor intensity of traditional manual addition of sand and gravel. The driving shaft drives the stirring rod and the cam to rotate at the same time. The stirring rod will initially disperse and crush the sand and gravel discharged from the sand discharge port, and the sand and gravel will fall onto the primary screen plate. The rotating cam drives the baffle to drive the primary screen plate to move back and forth left and right in the sleeve plate to sieve the sand and gravel. At the same time, the driven shaft drives the first bevel gear to rotate and then drives the second bevel gear and the crankshaft to rotate. The rotating crankshaft drives the connecting rod to drive the secondary screen plate to vibrate back and forth up and down to realize the secondary screening function.

[0004] However, although the above technical solution can play a good screening role, since sand and gravel usually need to be crushed after screening to avoid large pieces of sand and gravel occupying area, the device is not equipped with relevant crushing structure, which leads to excessive occupation of area and increased storage costs. For this reason, we provide a sand and gravel drying, grading and screening device. Utility Model Content

The sand and stone to be crushed in the crushing box 1 are crushed by the rotation of the second crushing barrel 20 and the first crushing barrel 14, and the crushed sand and stone flow out through the second discharge port 22, thereby preventing the occupation of too much area and reducing the storage cost.

[0026] See also Figure 1 , Figure 2 and Figure 3The fixed base 8 is connected to the outside of one end of the second motor 10, and a crushing box 1 is arranged in the middle of one end of the fixed base 8. The first motor 9 is connected to the inside of one end of the fixed base 8, and a cam 18 is movably connected to the output end of the first motor 9. A movable wheel 16 is arranged in the middle of the top of the cam 18, and a top block 17 is arranged in the middle of one end of the movable wheel 16. A screening plate 12 is arranged in the middle of the top of the top block 17, and a plurality of screening holes 13 are evenly distributed from top to bottom inside one end of the screening plate 12. A crushing box 1 is movably connected to the middle part of one end of the screening plate 12, a heating box 2 is provided in the middle part of the top end of the crushing box 1, a feed port 3 is provided in the middle part of the top end of the heating box 2, a hot air blower 4 is provided in the middle part of one end of the crushing box 1, a hot air pipe 6 is provided in the middle part of the top end of the hot air blower 4, an exhaust pump 5 is connected to the outside of one end of the hot air pipe 6, a nozzle 11 is provided in the middle part of one end of the hot air pipe 6, a first discharge port 7 is provided in the middle part of one end of the heating box 2, and the setting of the heating box 2 can achieve a drying effect.

[0027] When in use, firstly, the sand and gravel to be dried are transported into the interior of the heating box 2 through the feed port 3. When the sand and gravel fall downward in the heating box 2, the hot air generated in the hot air blower 4 is pumped into the interior of the hot air pipe 6 by starting the vacuum pump 5. The hot air in the hot air pipe 6 is discharged into the interior of the heating box 2 through the air nozzle 11 under the action of the vacuum pump 5, thereby drying the sand and gravel that are falling downward and to be dried in the heating box 2. When the dried sand and gravel fall on the top of the screening plate 12, the first motor 9 is started to The cam 18 is driven to rotate. When the raised side of the cam 18 rotates to the top, the movable wheel 16 is pushed up. In the process of pushing up, the movable wheel 16 pushes up the top block 17. In the process of pushing up, the top block 17 pushes up the screening plate 12. When the raised side of the cam 18 rotates to the bottom, the movable wheel 16 loses the upward pushing force and moves downward. The movable wheel 16 drives the top block 17 to move downward in the process of falling downward. The top block 17 drives the screening plate 12 to move downward. The screening plate 12 moves downward, and the cam 18 makes the screening plate 12 vibrate up and down. During the vibration of the screening plate 12, the sand and gravel with a diameter smaller than the screening hole 13 falls downward, and the sand and gravel with a diameter larger than the screening hole 13 moves out from the first discharge port 7 under the action of the screening plate 12, thereby achieving the effect of grading and screening. The second motor 10 is started to rotate, and the second motor 10 drives the rotation of the rotating rod 21 during the rotation. The rotating rod 21 drives the rotation of the second transmission gear 19 and the first transmission gear 15 during the rotation. The second transmission gear 19 drives the rotation of the second crushing drum 20 during the rotation. The first transmission gear 15 drives the rotation of the first crushing drum 14 during the rotation. The rotation of the second crushing drum 20 and the first crushing drum 14 crushes the sand and gravel to be crushed in the crushing box 1, and the crushed sand and gravel flows out through the second discharge port 22, thereby preventing the occupation of too much area and reducing the storage cost, thereby completing the crushing work of a sand and gravel drying and grading screening device.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
