[0002] Sand and gravel refer to a loose mixture of sand and crushed stone. In geology, mineral or rock particles with a particle size of 0.074 to 2 mm are called sand, and particles with a particle size greater than 2 mm are called gravel or angular cobbles. Due to their good hardness and stable chemical properties, sand and gravel are often used as high-quality building materials and concrete raw materials and are widely used in houses, roads, highways, railways, engineering and other fields.

When sand and gravel enter the hopper, sand and gravel with different particle sizes will be squeezed by each other and easily clogged at the discharge port of the hopper, which will affect the feeding speed of sand and gravel and reduce the sorting efficiency of the sand and gravel sorting device. Therefore, improvements are needed. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5As shown, the utility model provides a sand and gravel sorting device for civil construction, comprising a bracket 1, a vertical rod 2 is fixedly installed on the left and right sides of the top of the bracket 1, and the number of the vertical rods 2 is two. Slide blocks 3 are movably sleeved inside the two vertical rods 2, and the number of the slide blocks 3 is two. A lower hopper 4 is fixedly installed between the two slide blocks 3. The outer surface of the lower hopper 4 is movably connected to the outer surface of the vertical rod 2. The bottom ends of the two slide blocks 3 are fixedly installed with a connecting rod 5. The left and right sides of the top of the connecting rod 5 are movably sleeved with the inner surfaces of the two vertical rods 2 respectively, and the bottom end of the connecting rod 5 is fixedly sleeved with a fixed shaft 6. The outer surface of the fixed shaft 6 is movably sleeved with a round wheel 7. The outer surface of the round wheel 7 is movably sleeved with the inner surface of the bottom end of the connecting rod 5. The outer surface of the round wheel 7 is movably connected with an inclined block 8. The bottom end of the inclined block 8 is movably connected to the top of the bracket 1, and the left and right sides of the outer surface of the inclined block 8 are movably connected to the opposite surfaces of the two vertical rods 2. The rear side of the part is fixedly installed with a driving motor 9, and the other end of the output shaft of the driving motor 9 is fixedly sleeved with a driving shaft 10, and the outer surface of the driving shaft 10 is fixedly sleeved with an elliptical block 11, and the outer surface of the elliptical block 11 is movably connected to the outer surface of the inclined block 8; when the driving motor 9 is started, the driving shaft 10 will drive the elliptical block 11 to rotate. Since the outer surface of the elliptical block 11 is movably connected to the outer surface of the inclined block 8, as the elliptical block 11 rotates, the elliptical block 11 will generate a thrust on the inclined block 8, pushing the inclined block 8 to move, and as the inclined block 8 moves, the circular wheel 7 will be pushed, so that the circular wheel 7 moves upward with the fixed shaft 6, the connecting rod 5, the slider 3 and the lower hopper 4. When the elliptical block 11 rotates more than ninety degrees, under the action of gravity, the lower hopper 4 will return to its original position. This cycle is repeated to achieve the vibration of the lower hopper 4, thereby preventing the discharge port of the lower hopper 4 from being blocked.

[0022] Among them, a limiting groove 12 is opened on the right side of the top of the bracket 1, and the right end inside the limiting groove 12 is movably sleeved with a limiting block 13, and the top of the limiting block 13 and the bottom end of the inclined block 8 are fixedly connected; the inner surface of the limiting groove 12 and the outer surface of the limiting block 13 are both smooth, ensuring that the limiting block 13 will not get stuck when moving along the inside of the limiting groove 12. At the same time, the mutual cooperation between the limiting groove 12 and the limiting block 13 will limit the movement of the inclined block 8, thereby preventing the inclined block 8 from detaching during the movement.

[0023] Among them, support plates 14 are fixedly installed on the left and right sides of the front end of the bracket 1, and there are two support plates 14. The bottoms of the front ends of the two support plates 14 are movably connected with driving wheels 15; due to the existence of the support plates 14, the driving wheel 15 will be limited, thereby ensuring the stability of the rotation of the driving wheel 15, and the existence of the driving wheel 15 will provide power for the sand and gravel sorting device, so that the sand and gravel sorting device can operate normally.

[0024] Among them, a power motor 16 is fixedly installed at the bottom of the right side of the front end of the bracket 1, and the other end of the output shaft of the power motor 16 is fixedly sleeved with a power shaft 17. The left end of the power shaft 17 passes through the support plate 14 and extends to the outside of the support plate 14. The outer surface of the power shaft 17 and the inner surface of the driving wheel 15 are fixedly sleeved; when the power motor 16 is started, the power shaft 17 will rotate. Since the outer surface of the power shaft 17 and the inner surface of the driving wheel 15 are fixedly sleeved, the driving wheel 15 will rotate along the inner surface of the support plate 14 under the drive of the power shaft 17, thereby starting the sand and gravel sorting device to operate.

[0025] Among them, the top of the front end of the two support plates 14 is fixedly sleeved with a long rod 18, and the left and right sides of the outer surface of the long rod 18 are movably sleeved with auxiliary wheels 19 located inside the two support plates 14, and the outer surface of the auxiliary wheel 19 is movably sleeved with the inner surface of the support plate 14; due to the presence of the long rod 18 and the auxiliary wheel 19, it will provide assistance for the normal operation of the sand and gravel sorting device, thereby ensuring the stable operation of the sand and gravel sorting device, and then ensuring the normal progress of sand and gravel sorting.

[0026] Among them, the bottom of the outer surface of the auxiliary wheel 19 is movably connected with a ring 20, the bottom of the inner surface of the ring 20 is movably connected with the outer surface of the driving wheel 15, and the inside of the ring 20 is fixedly connected with a screen drum 21; when the driving wheel 15 rotates, since the inner surface of the ring 20 is movably connected with the outer surface of the driving wheel 15, under the joint action of the driving wheel 15 and the auxiliary wheel 19, the ring 20 will rotate with the screen drum 21, and the outer surface of the screen drum 21 is evenly provided with circular holes, so the existence of the screen drum 21 realizes the sorting of sand and gravel.

[0027] Among them, the inner surface of the screen drum 21 is fixedly installed with an auger blade 22, and the bottom of the outer surface of the screen drum 21 is movably connected with a discharge pipe 23, and the outer surface of the discharge pipe 23 is fixedly connected to the inner surface of the bracket 1; due to the presence of the auger blade 22, the sand and gravel will be blocked and intercepted after entering the screen drum 21, thereby reducing the impact force of the sand and gravel, so that the sand and gravel can be fully screened, and the presence of the discharge pipe 23 will collect and discharge the fine particles of sand and gravel screened out.

[0028] The working principle and use process of this utility model:

[0029] First, the operator starts the drive motor 9, so that the drive shaft 10 drives the elliptical block 11 to rotate, so that the elliptical block 11 generates a thrust on the inclined block 8, pushing the elliptical block 11 to move along the inner surface of the limiting groove 12 with the limit block 13. Since the contact surface of the inclined block 8 and the circular wheel 7 is an inclined surface, as the inclined block 8 moves, the circular wheel 7 will move upward with the fixed shaft 6 and the connecting rod 5, so that the lower hopper 4 moves along with the connecting rod 5 through the slider 3. When the elliptical block 11 rotates more than ninety degrees, the lower hopper 4 and the circular wheel 7 will return to their original position under the recovery effect of gravity, and this is repeated. Circulation can make the lower hopper 4 vibrate, and then the operator starts the power motor 16, so that the power shaft 17 drives the driving wheel 15 to rotate. At this time, the ring 20 will rotate with the screen drum 21 under the action of the driving wheel 15, and then the operator pours sand and gravel into the lower hopper 4. As the lower hopper 4 vibrates, the sand and gravel will fall into the screen drum 21 for sorting, so that the fine particles fall into the discharge pipe 23 through the circular holes on the screen drum 21, and the coarse particles slide out from the other end of the screen drum 21, thereby completing the sorting operation. With the mutual cooperation of various mechanisms, the lower hopper 4 can be prevented from being blocked, thereby accelerating the discharge rate of sand and gravel.
