Description

Technical Field

[0001] The utility model relates to the technical field of sand making machines, in particular to a feeding device for a sand making machine. Background Art

[0002] Sand and gravel refer to a loose mixture of sand particles and crushed stone. The structures of different sand and gravel vary greatly. Some have uniform particles, some vary in size, some have very good roundness in the debris, and some have sharp edges and corners in the debris. Sand and gravel are loose materials, but their particles are generally hard, and in the surface environment, their chemical properties are stable. For sandstone, its weathering resistance is generally strong, especially silicified quartz sandstone, its hardness exceeds that of granite. Sand and gravel are widely used in construction projects and need to be processed by sand making machines. Sand making machines are currently widely used in many departments such as large-scale, smelting, building materials, roads, railways, water conservancy and chemical industries.

[0003] The discharge mechanism of the existing sand making machine is generally equipped with a funnel-shaped discharge port. When the water content of the powder is high, it will become very viscous and easily accumulate, often blocking the discharge port. The blockage of the discharge port will cause production to stop, affecting production and processing efficiency. Manually cleaning the blockage of the discharge port is time-consuming and labor-intensive. Therefore, we need to propose a sand making machine discharge device. Utility Model Content

The other end of the rotating rod 601 passes through the blanking tube 2 and is connected to the rotating assembly. By arranging the rotating rod 601, the driving motor 602, the eccentric wheel 603, the L-shaped movable block 604, the guide rod 6051 and the telescopic spring 6052, the hollow tube 3 can be reciprocated in the vertical direction, and the sand and gravel inside the blanking tube 2 can be pounded to avoid the accumulation and blockage of sand and gravel;

[0022] The reset mechanism 605 includes a guide rod 6051, the two ends of which are fixedly mounted inside the through slot 4, an L-shaped movable block 604 being slidably connected to the outer wall of the guide rod 6051, a telescopic spring 6052 being fixedly connected to the inner top of the through slot 4, the bottom end of the telescopic spring 6052 being fixedly connected to the top of the L-shaped movable block 604, and the telescopic spring 6052 being movably sleeved on the outer wall of the guide rod 6051. By providing the telescopic spring 6052, the L-shaped movable block 604 is reset, thereby allowing the hollow tube 3 to fall rapidly.

[0023] The drive motor 602 is fixedly mounted on the upper surface of the mounting plate 5. One end of the output shaft of the drive motor 602 is fixedly connected to one end of the rotating rod 601. The drive motor 602 is configured as a forward and reverse stepping motor.

[0024] The rotating assembly includes a crown gear 701, which is fixedly sleeved on the outer wall of the rotating rod 601. A driven gear 702 is meshed with one side of the crown gear 701. A rotating shaft 703 is fixedly inserted into the interior of the driven gear 702. A dragon piece 704 is fixedly installed on the outer wall of the rotating shaft 703.

[0026] Working principle: When the present invention is used, after the sand and gravel fall into the guide hopper 1, the output shaft of the driving motor 602 drives the rotating rod 601 to rotate, thereby driving the eccentric wheel 603 to rotate, and then driving the L-shaped movable block 604 to perform a vertical reciprocating motion, thereby realizing a vertical reciprocating motion of the hollow tube 3, and tamping the sand and gravel inside the guide hopper 1 and the drop tube 2 to avoid the accumulation of sand and gravel and causing blockage. When the L-shaped movable block 604 moves upward, the telescopic spring 6052 will be compressed. When the L-shaped movable block 604 moves to the highest point, The L-shaped movable block 604 will fall down, and the rebound force of the telescopic spring 6052 makes the L-shaped movable block 604 fall down quickly, thereby resetting the L-shaped movable block 604, so that the eccentric wheel 603 can lift the L-shaped movable block 604 again. When the rotating rod 601 rotates, the crown gear 701 can be driven to rotate, thereby driving the driven gear 702 to rotate, and then driving the rotating shaft 703 to rotate, which can drive the dragon piece 704 to rotate, thereby achieving the effect of flipping and breaking up the sand and gravel inside the drop tube 2, avoiding the accumulation of sand and gravel, and ensuring the smoothness of sand and gravel discharge.
