[0007] The bottom of the silo is an oblique contraction structure.

[0008] As a further description of the above technical solution:

[0009] The silo is a cylindrical structure.

[0010] As a further description of the above technical solution:

[0011] The vibration ball shell is a hollow structure.

[0012] As a further description of the above technical solution:

[0013] The diameter length of the vibrating ball is smaller than the diameter length of the inner cavity of the silo.

[0014] As a further description of the above technical solution:

[0015] The diameter length of the vibrating ball is greater than the diameter length of the bottom opening of the silo.

[0016] Compared with the prior art, the utility model provides a crushing device for coated sand processing, which has the following beneficial effects:

[0017] 1. In the utility model, the original silo is changed from a rectangular structure to a cylindrical structure, and crushing nails are designed on its inner wall, so that the vibrated coated sand can rub against the crushing nails to accelerate the crushing speed;

[0018] 2. In the utility model, a vibrating ball is placed on the top of the coated sand, and the vibrating ball vibrates and hits the coated sand to accelerate the crushing speed of the coated sand. Moreover, the vibrating ball can stay at the bottom position of the silo and can roll and displace to have a large contact area with the coated sand, thereby crushing the coated sand as quickly as possible.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 2 The utility model provides a crushing device for coated sand processing, including a silo 1, a vibrator 2 is fixedly installed at the bottom of the silo 1, a screen 3 is fixedly installed at the bottom opening of the silo 1, a crushing nail 4 is provided on the inner wall of the silo 1, a vibrating ball 5 is placed in the silo 1, a crushing nail 4 is provided on the outer surface of the vibrating ball 5, and a connecting rope 6 is installed on the vibrating ball 5.

[0026] Specifically, Figure 1 As shown, the bottom of the silo 1 is an oblique contraction structure, and the silo 1 is a cylindrical structure, which is convenient for discharging and crushing movement of the vibration ball 5.

[0027] Specifically, the shell of the vibration ball 5 is a hollow structure, which is convenient for the built-in vibration device.

[0028] Specifically, the diameter of the vibration ball 5 is smaller than the diameter of the inner cavity of the silo 1 , and the diameter of the vibration ball 5 is larger than the diameter of the bottom opening of the silo 1 , so as to prevent the vibration ball 5 from being stuck or falling.

[0029] Working principle:

[0030] When in use, the old coated sand blocks are put into the silo 1, and the silo 1 is supported by a support frame. The connecting rope 6 can be connected to the support frame and to the outer shell of the silo 1. A vertical frame connection can be set, and the vibrating ball 5 is put into the silo 1. The vibrator 2 works to vibrate and crush the coated sand blocks. At the same time, the vibrating ball 5 also presses on the coated sand blocks and vibrates. The vibrating and undulating coated sand blocks rub against the crushing nails 4, which speeds up the crushing speed, and the crushed sand falls after being filtered through the screen 3.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
