Description

Technical Field

[0001] The present invention relates to the technical field of concrete production, in particular to a batching and crushing device for concrete production. Background Art

[0002] Concrete batching refers to the use of recycled or discarded materials as components of concrete. This approach helps protect the environment and reduces waste by reducing the demand for raw materials. Common sources of concrete batching include demolished buildings, concrete waste and industrial waste. Concrete batching needs to undergo rigorous screening and processing to ensure that it meets construction standards and performance requirements. Recycled materials are crushed and screened to remove any impurities and unqualified parts. The recycled materials are then mixed with fresh cement, sand and gravel to form concrete with the required strength and durability.

[0003] In the existing concrete batching production, the recycled ingredients are crushed, and most of them are crushed by a single crushing device. However, the particle sizes of the crushed ingredients still vary greatly, and there are still large ingredients. If these large-sized ingredients are directly recycled and reused, the carrying load of subsequent recycling equipment will increase, and production efficiency will be reduced. At the same time, the large-volume ingredients are mixed with new aggregates to form new concrete. The particle surface of the recycled ingredients in the new concrete is uneven, which will increase the porosity, thereby affecting the use effect of the concrete. Summary of the Invention

[0004] The object of the present invention is to provide a batching crushing device for concrete production to solve the problems raised in the above background technology.

[0008] As a further improvement of the present technical solution, the crushing device includes an L-shaped plate arranged inside the body, and the interior of the L-shaped plate is slidably connected to the outer wall of the moving rod. A No. 1 rolling plate is provided on the L-shaped plate, and one end of the No. 1 rolling plate is fixedly connected to one end of the moving rod.

[0009] As a further improvement of the present technical solution, the internal sliding connection of the L-shaped plate is provided with a receiving plate, one side of the receiving plate is fixedly connected to the internal side of the L-shaped plate with a compression spring, and the receiving plate is arranged on an inclined surface on one side away from the compression spring. The movement of the moving rod drives the L-shaped plate to move, and the L-shaped plate drives the receiving plate to receive the ingredients. When the receiving plate is against one side, the receiving plate slides inside the L-shaped plate and squeezes the compression spring until the compression spring is fitted with one side. The moving rod drives the No. 1 rolling plate to continue to move, so that the No. 1 rolling plate pushes the ingredients for crushing.

[0010] As a further improvement of the present technical solution, a side plate is fixedly connected to the interior of the machine body, and a No. 2 rolling plate is fixedly connected to the inner wall of the machine body and one side of the side plate. The lower side of the No. 2 rolling plate is flush with the inner upper side of the L-shaped plate, and a number of staggered protrusions are provided on the adjacent side of the No. 2 rolling plate and the No. 1 rolling plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the batching and crushing device for concrete production, two moving rods move in opposite directions to drive two L-shaped plates to crush the ingredients in turn. At the same time, the two L-shaped plates are staggered during crushing. When the upper L-shaped plate takes over the crushing, the lower L-shaped plate drops the material.

A mounting box 12 is fixedly connected to one side of the body 1, and a moving device 2 is arranged inside the mounting box 12. The moving device 2 reciprocates to drive the two groups of crushing devices 3 to move in the opposite direction. When the batching falls onto the crushing device 3 above, the crushing device 3 moves to crush the batching. The crushed ingredients fall into the crushing device 3 below for re-crushing to prevent the crushed ingredients from being mixed with larger ingredients, which is inconvenient for subsequent use of the ingredients. The crushed ingredients fall onto the screen 13 for screening. At the same time, when the crushing device 3 below moves, it drives the auxiliary device 4 to rotate 180 degrees. The auxiliary device 4 rotates to push the larger ingredients on the screen 13 upward, and the moved ingredients fall onto the crushing device 3 below, so that the crushing device 3 below crushes the larger ingredients, which is convenient for thorough crushing of the ingredients, thereby improving the crushing efficiency of the ingredients.

[0021] See also Figure 2 and Figure 3 as well as Figure 6 As shown, the moving device 2 includes a motor 21 fixedly connected to one side of the installation box 12, and the output end of the motor 21 passes through the interior of the installation box 12 and is fixedly connected to a turntable 22, one side of the turntable 22 is rotatably connected to a connecting rod 23, and the interior of the installation box 12 is fixedly connected to a fixed rod 24, a rocker rod 25 is rotatably connected to the fixed rod 24, and one end of the rocker rod 25 is rotatably connected to one end of the connecting rod 23, and both ends of the rocker rod 25 are rotatably connected to a moving rod 26, and the moving rod 26 passes through the interior of the machine body 1. When the motor 21 is started, the turntable 22 is driven to rotate, and the rotation of the turntable 22 drives the connecting rod 23 to rotate. Since the position of the fixed rod 24 is fixed, the connecting rod 23 drives the rocker rod 25 to swing when it rotates, and the rocker rod 25 is in a tilted state when it swings, so that the swing of the rocker rod 25 drives the moving rod 26 to move in the opposite direction.

After crushing, the larger ingredients are located on the screen 13. The feeding plate 45 rotates to push the crushed ingredients upward. When the L-shaped plate 31 below is in contact with one side of the No. 2 rolling plate 38, the feeding plate 45 transports the larger ingredients on the screen 13 to the top of the screen 13. The upper side of the side plate 36 is fixedly connected to the inclined plate 46, and the inclined plate 46 is tilted. When the feeding plate 45 rotates 180 degrees, the feeding plate 45 does not contact the inclined plate 46. At this time, the ingredients located above the screen 13 fall from the inclined plate 46 to the L-shaped plate 31 below. The larger ingredients are crushed by the No. 1 rolling plate 33 and the No. 2 rolling plate 38, which facilitates the thorough crushing of the ingredients, thereby improving the crushing efficiency of the ingredients.

[0025] When the batching crushing device for concrete production of the present invention is used, the rotation of the turntable 22 drives the connecting rod 23 to rotate.

The movement of the moving rod 26 drives the L-shaped plate 31 to move. The two moving rods 26 move in the opposite direction, so that the two L-shaped plates 31 can be driven to crush the batching in sequence. When the upper L-shaped plate 31 crushes the ingredients, the lower L-shaped plate 31 drives the receiving plate 32 to move toward the side of the second rolling plate 38, so that the crushed ingredients on the top fall onto the lower L-shaped plate 31, and the ingredients are crushed again, so as to prevent the crushed ingredients from being mixed with larger ingredients, which is inconvenient for subsequent use of the ingredients, thereby improving the crushing effect of the ingredients; When the lower L-shaped plate 31 moves toward the side of the No. 2 rolling plate 38, the L-shaped plate 31 drives the moving plate 41 to move, and the moving plate 41 drives the rack to move, and the rack and the gear 43 are engaged and transmitted, so the moving plate 41 drives the rotating shaft 42 to rotate, and the rotating shaft 42 drives the roller 44 and the feeding plate 45 to rotate 180 degrees.
