Description

Technical Field

[0001] The invention relates to the technical field of sand and gravel mixing, in particular to a sand and gravel mixing device. Background Art

[0002] Sand and gravel refers 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 larger than 2 mm are called gravel or angular gravel. Sand and gravel are often used as high-quality building materials and concrete raw materials due to their good hardness and stable chemical properties. They are widely used in housing, roads, highways, railways, engineering and other fields; Sand and gravel need to be screened before mixing. After screening, the sand and gravel need to be piled together and wait for mixing processing. However, after being piled for a long time, the sand and gravel are easy to condense together due to moisture. The condensed sand and gravel easily affect the mixing effect of the sand and gravel. When the current sand and gravel mixing device mixes sand and gravel, it is difficult to break up the condensed sand and gravel by stirring, resulting in poor mixing efficiency of sand and gravel.

DETAILED DESCRIPTION

[0022] 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.

The breaking component 6 is used to initially break up the coagulated sand and gravel, and the stirring component 7 is used to cooperate with the sieve frame 22 to screen out qualified sand and gravel.

[0025] Specifically, the breaking up assembly 6 includes a conical hole frame 13, a positioning ring 11 and a limiting ring 14. The outer edge of the conical hole frame 13 is fixedly connected to the inner side of the mixing tank 1. The limiting ring 14 and the positioning ring 11 are fixedly arranged on the rotating rod 10. The positioning ring 11 is hinged with a plurality of scrapers 15 along the circumferential direction. The upper end of the scraper 15 is connected to the limiting ring 14 through a connecting plate 12. Preferably, the connecting plate 12 is a spring plate, and a slope is arranged on one side of the scraper 15 along the rotation direction. When the scraper 15 works normally, the outer side surface of the scraper 15 fits with the inner side surface of the conical hole frame 13, pushing the raw materials in the conical hole frame 13 to move along the conical hole frame 13 to achieve screening. When the scraper 15 encounters a jam, since the connecting plate 12 is compressible, the scraper 15 can use the slope to overcome the jam to avoid machine failure.

[0026] In order to improve the breaking up effect, a breaking up frame 16 is fixedly connected between the positioning ring 11 and the limiting ring 14, and a separation plate 18 is fixedly connected to the outer side of the breaking up frame 16.

The air outlet 44 is provided on the side of the fixed plate 23 away from the rotation direction, and a dustproof net is provided on the outside of the air outlet 44 to prevent blockage by sand and gravel.

[0029] In order to discharge the sand and gravel with a particle size larger than that of the sieve frame 22, a pushing component 8 is provided on the sieve frame 22. Specifically, the pushing component 8 includes an inclined plate 36 and a movable plate 37. A groove 38 is provided on one side of the upper end surface of the sieve frame 22. An opening and a storage rack 4 corresponding to the groove 38 are provided on the side wall of the mixing tank 2. The opening is used to discharge the sand and gravel, and the storage rack 4 is used to temporarily store the sand and gravel that do not meet the particle size. A positioning hole 40 connected to the groove 38 is provided on the inner side of the sieve frame 22. An inclined plate 36 is slidably provided in the groove 38. A movable plate 37 fixedly connected to the inclined plate 36 is slidably provided in the positioning hole 40. A driving mechanism for pushing the movable plate 37 to slide along the positioning hole 40 is provided on the rotating rod 10, and the inclined plate 36 is driven to move by the movable plate 37.

[0030] The upper end surface of the inclined plate 36 is inclined downward along the side away from the opening, and the bottom of the inclined plate 36 contacts the inner bottom of the groove 38, so that when the inclined plate 36 moves toward the rotating rod 10, the sand and gravel in the groove 38 can be shoveled. Slide grooves 42 are provided on both sides of the groove 38, and the sliding plates 32 are fixedly connected on both sides of the inclined plate 36, and the sliding plates 32 are slidably connected to the slide grooves 42.

[0031] A baffle 39 is provided at the upper end of the groove 38, and a leakage hole 41 connected to the groove 38 is provided on the baffle 39. Sand and gravel with larger particle sizes enter the groove 38 through the leakage hole 41. A bending part cooperating with the opening is provided on the side of the baffle 39 close to the opening, and the bending part prevents the unscreened sand and gravel from being directly discharged.

[0032] In order to drive the moving plate 37 to move, the bottom of the moving plate 37 is fixedly connected to the force plate 31, and the bottom of the force plate 31 is fixedly connected to the spring sheet 33. The end of the spring sheet 33 away from the force plate 31 is fixedly connected to the bottom of the sieve frame 22, and the force plate 31 is automatically reset by the spring sheet 33.

When the extrusion frame 30 rotates with the rotating rod 10, the push plate 35 is driven to rotate and push the sand and gravel out of the mixing tank 1.

[0034] When in use, after putting sand and gravel into the conical hole frame 13, the motor 5 is started to drive the rotating rod 10 to rotate. When the rotating rod 10 rotates, the scraper 15 is driven to rotate through the positioning ring 11. The scraper 15 is used to stir the sand and gravel to rotate inside the conical hole frame 13 to break up the sand and gravel to prevent the wet sand and gravel from condensing together and affecting the mixing effect. When the rotating rod 10 rotates, it drives the separation plate 18 to hit the sand and gravel through the scattering frame 16 to improve the breaking efficiency of the sand and gravel. The broken sand and gravel will pass through the conical hole frame 13 into the interior of the mixing tank 1 for mixing. After passing through the conical hole frame 13, the sand and gravel will fall to the top of the sieve hole frame 22. The rotating ring 20 drives the fixed plate 23 to rotate through the rotation of the rotating rod 10. When the fixed plate 23 rotates, it drives the sand and gravel to roll on the top of the sieve hole frame 22 through the scraper plate 24 to mix the sand and gravel. When the fixed plate 23 rotates, it drives the separation block 21 to push the sand and gravel for extrusion. 21 squeezes and separates the sand and gravel to prevent the sand and gravel from accumulating inside the mixing tank 1 and affecting the mixing effect. When the rotating rod 10 rotates, the force-bearing plate 31 is pushed to move by the squeezing frame 30. When the force-bearing plate 31 moves, the inclined plate 36 is pushed to move inside the groove 38 by the moving plate 37. After the mixing of the sand and gravel is completed, the sand and gravel that meet the specifications will fall to the bottom of the inner wall of the mixing tank 1 through the sieve frame 22, and some larger sand and gravel will enter the inside of the groove 38 through the leakage hole 41. When the inclined plate 36 moves, the larger sand and gravel will fall to the inside of the storage frame 4 for collection. When the inclined plate 36 retracts through the spring piece 33, the sand and gravel inside the groove 38 will be shoveled up. At this time, the sand and gravel that falls into the groove 38 will also be screened again through the sieve frame 22. When the squeezing frame 30 rotates, the pushing plate 35 is driven to rotate by the bent plate 34. When the pushing plate 35 rotates, the mixed sand and gravel can be pushed out of the mixing tank 1 for collection and processing.
