[0002] In the foundry industry, the vibrating sand shaker is one of the indispensable equipment, which is mainly used to vibrate and crush the used molding sand so that the molding sand can be recycled.

[0003] Regarding the vibrating sand-falling machine, in the prior art, after searching, the utility model patent with the Chinese patent publication number CN205074524U discloses a vibrating sand-falling machine, such as Figure 1 As shown, it mainly includes a base a, a vibration box b is arranged on the base a, an inclined transition plate c is arranged on the front side of the vibration box b, and a sand collecting hopper d is arranged below the inclined transition plate c.

[0004] In the prior art, the vibrating sand shakeout machine similar to the above-mentioned technical solution was found to have some room for improvement during use: the vibration-crushed molding sand was not screened, resulting in the larger particles and loose sand in the crushed molding sand being concentrated together, making it inconvenient to crush the large pieces of molding sand again separately, thereby affecting the subsequent recycling and reuse of the loose sand. Utility Model Content

[0005] In view of the deficiencies and defects in the prior art, the purpose of the present invention is to provide a vibrating sand shakeout machine, which solves the problem that the vibrating sand shakeout machine in the prior art does not screen the vibration-crushed molding sand, resulting in larger particles and loose sand in the crushed molding sand being concentrated together, making it inconvenient to crush the large pieces of molding sand again separately, thereby affecting the subsequent recycling and reuse of the loose sand.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a vibrating sand shaker, comprising a base and a collecting hopper, a vibrating motor is arranged on the base, a vibrating box is fixed on the upper side of the base, the bottom of the vibrating box is gradually inclined downward from left to right, and a screen is arranged in the middle of the vibrating box as a whole and gradually inclined downward from left to right. The screen comprises a plurality of screening crushing plates arranged in sequence from front to back, the shape of the screening crushing plates is wavy, and a plurality of running wheels are rotatably connected between adjacent screening crushing plates, a plurality of support plates that can support the screening crushing plates are fixed on the front and rear inner walls of the vibrating box, a small inclined plate that gradually inclined downward from left to right is provided on the right side of the bottom of the vibrating box, and a large inclined plate that gradually inclined downward from left to right is fixed on the right side of the sieve on the vibrating box, the collecting hopper is arranged below the right side port of the large inclined plate, and a crushing part is arranged in the collecting hopper.

[0007] As a further improvement of the present invention, the crushing member includes a rotating shaft, which is rotatably connected to the inner wall of the collecting hopper. One end of the rotating shaft extends out of the collecting hopper and is connected to the rotating motor. Multiple crushing blades are fixed on the rotating shaft.

[0008] As a further improvement of the present invention, a plurality of pointed cones are provided at the bottom of the collecting hopper.

[0009] As a further improvement of the present invention, baffles are fixed on the front and rear sides of the large inclined plate.

[0010] As a further improvement of the present invention, the upper side of the left wall of the vibration box is gradually tilted to the left from bottom to top.

[0011] As a further improvement of the present invention, a crushing knife is provided on the rotating wheel.

[0012] As a further improvement of the present invention, a small sharp knife is provided at the bottom of the vibration box.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. By setting a vibration box above the base of the vibrating sand shaker and setting a screen in the vibration box, the screen divides the vibration box into an upper screening part and a lower fine material part. After the molding sand enters the vibration box from the upper left side of the vibration box, the molding sand gradually moves from left to right during the continuous vibration of the vibration box. In the process of continuous movement of the molding sand, the molding sand is continuously vibrated into bulk material. In this process, the fine bulk material falls from the gap between the screening and crushing plates to the bottom of the vibration box, moves from the bottom of the vibration box to the small inclined plate, and finally falls onto the return belt, while the larger pieces of molding sand continue to move to the right and finally fall into the collecting hopper. After being crushed again in the collecting hopper, they are recycled. During the whole process, the molding sand and loose sand are screened in the process of vibration crushing, so that the loose sand returned to the recovery bin does not contain large pieces of sand, ensuring the recycling effect of the molding sand. In addition, by setting crushing parts in the collecting hopper, large pieces of molding sand can be crushed separately, improving the crushing effect and recovery efficiency of the molding sand.

[0015] 2. By setting a pointed cone at the bottom of the aggregate hopper, the molding sand can be crushed when the molding sand blocks fall onto the pointed cone.

[0016] 3. By installing a small sharp knife at the bottom of the vibration box, the sand can be crushed again to avoid sand sticking. BRIEF DESCRIPTION OF THE DRAWINGS
