[0037] Specifically, referring to Figure 3 and Figure 4 shown, in some embodiments, the first screen 1 includes four arc-shaped first sub-sieves 102, two end faces of the first sub-sieve 102 are provided with arc-shaped first rib plates 103, two sides of the first sub-sieve 102 are provided with strip-shaped second rib plates 104, and a plurality of mounting holes 100 are provided on the first rib plate 103 and the second rib plate 104 to realize bolt connection with other components through the mounting hole 100.

[0038] Referring to Figure 5 and Figure 6 shown, four arc-shaped first sub-sieves 102 are connected by mounting holes 100 of the second rib plate 104 and bolts 200 to form the first screen 1.It should be noted that the cross section of the first rib plate 103 and the first sub-sieve 102 is set to one-fourth circular arc shape, so as to facilitate the connection of four first sub-sieves 102 into circular first screen 1.In addition, the second rib plate 104 on both sides is vertically arranged between the first sub-sieve 102, and the second rib plate 104 protrudes outward by a part, so as to facilitate the connection between adjacent first sub-sieves 102.

[0039] Referring to Figure 7 and Figure 8As shown, in some embodiments, the second screen 2 comprises four arc-shaped second sub-screens 202, two end faces of the second sub-screens 202 are provided with arc-shaped third reinforcing plates 203, two side edges of the second sub-screens 202 are provided with strip-shaped fourth reinforcing plates 204, a plurality of mounting holes 100 are arranged on the third reinforcing plates 203 and the fourth reinforcing plates 204, and the four arc-shaped second sub-screens 202 are connected through the mounting holes 100 of the fourth reinforcing plates 204 and the bolts 200 to form the second screen 2. The second screen 2 is different from the first screen 1 in length and screen hole size, and other connection ideas are consistent with the first screen 1, which will not be described here.

[0040] In some embodiments, the first reinforcing plate 103 protrudes outward relative to the first screen 1, the third reinforcing plate 203 protrudes outward relative to the second screen 2, and the first screen 1 and the second screen 2 are connected through the mounting holes 100 of the first reinforcing plate 103, the mounting holes 100 of the third reinforcing plate 203, and the bolts 200. It should be noted that the diameter of the first screen 1 and the diameter of the second screen 2 are consistent, the diameter of the first reinforcing plate 103 and the diameter of the third reinforcing plate 203 are consistent, the mounting holes 100 of the first reinforcing plate 103 and the mounting holes 100 of the third reinforcing plate 203 are positionally corresponding, and then the first screen 1 and the second screen 2 can be connected through the bolts 200, and when disassembling, the bolts 200 can be unscrewed.

[0041] In some embodiments, the first reinforcing plate 103 and the third reinforcing plate 203 can also be fixed through the clamp 300 to connect the first screen 1 and the second screen 2. Referring to Figure 9 As shown, the clamp 300 comprises a first half clamp 301, a second half clamp 302, and a locking screw 303, one end of the first half clamp 301 and the second half clamp 302 is rotatably connected, and the other end of the first half clamp 301 and the second half clamp 302 is locked and fixed or disassembled through the locking screw 303. It should be noted that recesses are formed in the inner sides of the first half clamp 301 and the second half clamp 302, so as to surround the edges of the first reinforcing plate 103 and the third reinforcing plate 203 in the recesses, and then after the first half clamp 301 and the second half clamp 302 are locked through the locking screw 303, the fixing of the first reinforcing plate 103 and the third reinforcing plate 203 is completed, that is, the connection of the first screen 1 and the second screen 2 is completed. When disassembling, the locking screw 303 can be loosened to complete the disassembly.

[0042] The bolt connection and the clamp connection between the first screen 1 and the second screen 2 can be either one or both. It is preferred that the first screen 1 and the second screen 2 are first fixed through the bolt connection and then fixed through the clamp connection, and such a fixing mode is more reliable.

[0043] Referring toFigure 1 As shown, in some embodiments, the second screen 2 is provided with a second flange plate 4 at the end, the output shaft of the motor 5 is connected in the center of the second flange plate 4, the motor 5 is electrically connected with the control cabinet 6, the speed regulating circuit is arranged in the control cabinet 6, the speed regulating circuit includes three speed settings and forward and reverse rotation settings. The speed and direction of rotation of the motor 5 are controlled by the speed regulating circuit, and then the second flange plate 4 drives the second screen 2 and the first screen 1 to rotate in the same direction and speed.

[0044] Reference Figure 10 As shown, when the switches are closed on R, S, and T respectively, they represent three different speeds, for example, low speed on R, medium speed on S, and high speed on T. When screening the ball, generally, low speed or medium speed is set first to run, so that the steel ball is fully screened; but during the low speed or medium speed screening process, the steel ball with a diameter larger than the screen hole may be stuck in the screen hole, at this time, if the uniform speed rotation is maintained, it is difficult to shake out these stuck balls, which affects normal screening, so the speed is adjusted to high speed, and after the ball is shaken out by high speed rotation, the speed is adjusted back to low speed or medium speed for normal screening. In addition, when the switches are closed on DI 1 and DI 2 respectively, they represent two different rotation directions, for example, forward rotation on DI 1 and reverse rotation on DI 2; through the direction adjustment of forward and reverse rotation, the stuck balls can be shaken out more easily.

[0045] Reference Figure 1 As shown, in some embodiments, the first screen 1 is provided with a first flange plate 3 at the front end, and support rollers 7 are arranged below the first flange plate 3 and the second flange plate 4. The support rollers 7 can be provided with four, two below the first flange plate 3 and two below the second flange plate 4, which support the first screen 1 and the second screen 2 as a whole. When the motor 5 drives the first screen 1 and the second screen 2 to rotate, the first flange plate 3 and the second flange plate 4 rotate on the support rollers 7.

[0046] In some embodiments, the first screen 1 is provided with a feeding port 8 outside, the first screen 1 is provided with a first discharge port 9 below, the second screen 2 is provided with a second discharge port 10 below, and the second screen 2 is provided with a third discharge port 11 outside. The diameter of the steel ball discharged from the first discharge port 9 is smaller than the diameter of the first screen hole 101, the diameter of the steel ball discharged from the second discharge port 10 is smaller than the diameter of the second screen hole 201, and the diameter of the steel ball discharged from the third discharge port 11 is greater than the diameter of the second screen hole 201. It should be noted that the feeding channel of the feeding port 8 extends to the gap of the first flange plate 3, and it is necessary to ensure that the first flange plate 3 does not contact the feeding channel during rotation. The feeding channel is inclined downward, and in use, the steel ball enters the gap of the first flange plate 3 from the feeding channel of the feeding port 8, and then enters the first screen 1, and then the screening starts.

[0047] In some embodiments, the length of the first screen 1 is greater than the length of the second screen 2. The reason for such an arrangement is that the number of steel balls of various diameters is not the same, in general, the number of small-diameter steel balls is large, and the number of large-diameter steel balls is small, so the length of the first screen 1 with small screen holes is set a little longer to ensure good screening effect.

[0048] In some embodiments, the first screen 1 and the second screen 2 are integrally arranged at an inclination, wherein the front end of the first screen 1 is located higher than the end of the second screen 2. It should be noted that the inclination angle does not need to be too large, only to ensure that the whole inclination arrangement can make the steel balls move backward when rotating.

[0049] In some embodiments, a plurality of pulleys 12 are arranged below the device housing, which can be conveniently moved through the pulleys 12; the pulleys 12 have a locking function to lock when not needed to move.

[0050] Working principle: in use, first select and install the screen according to the screening range required, after installation, start the ball screening machine at low speed, feed the steel balls to be screened from the feeding port 8, observe the screening effect, if there are many steel balls stuck, adjust the rotating speed and direction through the control cabinet 6 to throw out the stuck steel balls, to optimize the screening effect. With the working of the ball screening machine, finally three kinds of steel balls with different particle size ranges can be obtained from the first discharge port 9, the second discharge port 10 and the third discharge port 11, to achieve the purpose of screening balls. If the screening range needs to be adjusted, the screen can be selected, disassembled and assembled to achieve the purpose of adjusting the screening range.

[0051] In summary, the ball screening device with adjustable screening range provided in the embodiments of the present application can conveniently replace screens with different screen hole sizes through the detachable connection of the first screen and the second screen, thereby adapting to more screening range requirements.

[0052] In addition, the traditional ball screening machine usually has a fixed rotating speed, which results in poor screening effect and easy occurrence of the situation that the steel balls are stuck in the screen holes and cannot be thrown out, affecting the use effect. In view of this problem, the present application further sets a speed regulation circuit to make the rotating speed of the ball screening machine adjustable, so that the stuck steel balls in the screen holes can be thrown out through speed change, avoiding the situation that too many steel balls are stuck to affect the use effect, thereby achieving the purpose of optimizing the screening effect.

[0053] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, rather than limiting them; under the idea of the present application, the technical features in the above examples or different examples can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in detail for simplicity; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
