Description

A sand making machine for construction fine sand production line

Technical Field

The utility model relates to the technical field of sand making machines, in particular to a sand making machine for a construction fine sand production line.

Background Art

Sand making machine is a kind of production equipment, which is widely used for fine crushing of various materials. The materials fall vertically from the upper part of the machine into the high-speed rotating impeller. Under the action of high-speed centrifugal force, they collide and crush with the other part of the materials which are diverted around the impeller in an umbrella form at high speed. After colliding with each other, the materials will form vortex between the impeller and the casing, and they will collide and rub against each other many times and be crushed, and then be discharged directly from the bottom.

However, when the existing crushing and sand making machine produces finished products, it is impossible to grind all the sand and gravel to the appropriate size at one time due to the crushing effect. Therefore, the finished products need to be put into the machine again for re-crushing. This process cannot only put in substandard materials, but also put in the sand that has reached the standard, so the resource utilization rate is low. Therefore, in order to improve the production efficiency of the sand making machine, some technologies have proposed relevant technical structures to assist the use of the sand making machine. For example, there is a utility model patent with the announcement number CN215389676U, which proposes an efficient crushing and sand making machine for mining. The larger particles under the screen are moved to the position of the lower trough due to the vibration of the vibration motor, and fall through the lower trough. The collected materials are put into the sand making machine body again, and the materials that do not meet the specifications can be reprocessed, avoiding waste of resources and facilitating the use of users.

From the above disclosed technical content, theoretically speaking, the implementation of the relevant technical structure is conducive to improving the efficiency of the sand making machine. However, according to the description in the above disclosed technical content, after the crushing process of the sand making machine is completed, the fine material and the reworked material are separated by a screen. However, when the material passes through the sieve holes of the screen, the material is very easy to get stuck in the sieve holes of the screen. As the number of material blockages in the sieve holes of the screen continues to increase, the blocked area of the screen also increases. At this time, the screen will be completely blocked by the material, which brings inconvenience to the screening of the material. Moreover, if the material is stuck in the sieve holes of the screen for a long time, it will also cause the deformation of the sieve holes of the screen, thereby affecting the effect of the screen on material screening.

Working principle: When in use, first, the crushed materials inside the body 1 fall from the discharge end 11 onto the sieve plate 2, and the small particles on the sieve plate 2 fall from the sieve hole 13 onto the conveyor belt 8, while the large particles fall from the drop port 14 and are collected, so that the large particles can be collected and added to the inside of the body 1 again from the feeding end 9. Then, in order to prevent the materials from getting stuck in the sieve hole 13, the power of the rotating motor 17 is turned on. After the rotating motor 17 is turned on, it drives the rotation of the ball screw 702. Since the ball screw 702 and the ball screw The threaded sleeve connection of the female 701 allows the ball screw 702 to rotate in a circular direction while also realizing the horizontal movement of the ball nut 701. While the ball nut 701 is moving, the connection with the fastening assembly 6 drives the dredging brush 3 to reciprocate under the sieve plate 2, so that the dredging brush 3 dredges the sieve holes 13. Finally, the small-particle materials smoothly fall from the sieve holes 13 onto the conveyor belt 8. The opening of the power device 21 drives the rotation of the conveyor belt 8 through the connection with the rotating shaft 19, so that the small-particle materials that fall onto the conveyor belt 8 are easy to collect after discharging.
