DETAILED DESCRIPTION

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] See also Figure 1-4As shown, a metal wear-resistant ball screening device comprises a screening box 1 arranged obliquely, a connected filter box 2 is installed at the bottom of the screening box 1, and a feed pipe 3 is installed at the top of the screening box 1, and the metal wear-resistant balls to be screened enter from the feed pipe 3 and move to the filter box 2 through the screening box 1;

[0027] A power belt 4 is installed inside the screening box 1. In this embodiment, the power belt 4 adopts a conveyor belt structure. The power belt 4 is used to provide power to the metal wear-resistant balls, and a plurality of groups of screening bars 5 are installed on the upper side of the power belt 4 inside the screening box 1. Each screening bar 5 is inclined to extend to the outside of the screening box 1, and an angle is set between the inclination direction of the screening bar 5 and the rotation direction of the power belt 4. When the metal wear-resistant balls roll on the power belt 4, they contact the screening bars 5. After the broken or surface-damaged metal wear-resistant balls contact the screening bars 5, they are stopped from moving, and as the power belt 4 continues to rotate, they move along the screening bars 5 to the outside of the screening box 1.

[0028] See also Figure 2 As shown, a connection box 9 is installed on the upper side of the screening box 1, and a plurality of elastic members 10 are installed inside the connection box 9. A baffle member 11 is installed at the bottom end of each elastic member 10 for limiting the bouncing height of the metal wear-resistant ball.

[0029] See also Figure 4 As shown, a filter assembly 6, a storage box 7 and a recovery box 8 are installed in the filter box 2 from top to bottom, wherein the filter assembly 6 is arranged at the lower side of the connecting portion between the filter box 2 and the screening box 1, and when the metal wear-resistant balls pass through, the metal wear-resistant balls with a diameter larger than the sieve holes are screened out, and the storage box 7 and the recovery box 8 are installed to the inside of the filter box 2 by pulling.

[0030] The storage box 7 includes a box body 71, wherein an entry chamber 72 and a storage chamber 73 are connected to each other, a second filter plate 74 is installed inside the entry chamber 72, and the box body 71 is inclined toward the storage chamber 73;

[0031] The upper and lower ends of the entry bin 72 are communicated with the upper and lower sides of the box body 71 respectively.

[0032] A guide plate 12 is installed inside the filter box 2 between the filter assembly 6 and the storage box 7 . The guide plate 12 is inclined toward the entry bin 72 to guide the metal wear-resistant balls screened by the filter assembly 6 into the entry bin 72 .

[0033] The filter assembly 6 includes a mounting groove 61 and a first filter plate 62. The mounting groove 61 is provided in two groups, and the two groups of mounting grooves 61 are arranged in parallel.

[0034] When the installation slot 61 is in use, it is assembled into any installation slot 61, and after a period of use, a new set of first filter plates 62 is assembled into the unused installation slot 61, and the used first filter plates 62 are extracted for cleaning to prevent the metal wear-resistant balls from clogging the sieve holes of the first filter plates 62;

[0035] In this embodiment, the first filter plate 62 adopts a box-shaped structure, the bottom of which is a screening area, and the edge of the screening area extends upward to cover the edge of the screening area, thereby facilitating the storage of the screened metal wear-resistant balls.

[0036] When the utility model is in use, the metal wear-resistant balls to be screened are poured from the feed pipe 3 into the screening box 1, and the power belt 4 in the screening box 1 drives each metal wear-resistant ball to move. When the metal wear-resistant balls are moving, the broken or surface-damaged metal wear-resistant balls have a large contact area, and the damaged surface is attached to the upper side of the power belt 4. When passing through the screening bar 5, the metal wear-resistant balls move along the screening bar 5 to the outside of the screening box 1. The metal wear-resistant balls with intact surfaces roll on the power belt 4, and based on the kinetic energy of the power belt 4, when contacting the screening bar 5, they pass over the upper side thereof, and the moving height of the metal wear-resistant balls is limited by the baffle member 11 and the elastic member 10.

[0037] After the screened metal wear-resistant balls enter the filter box 2, they are screened for the first time by the first filter plate 62 to remove the metal wear-resistant balls with too large diameters. The metal wear-resistant balls enter the storage box 7 along the guide plate 12 and fall on the second filter plate 74. The metal wear-resistant balls with smaller diameters pass through the second filter plate 74 and fall into the recovery box 8.

[0038] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
