[0022] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0023] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1 and Figure 2 and Figure 3 As shown, it includes a ball storage frame 1, which has a bottom surface 11 at the bottom. The bottom surface 11 is inclined and has a lower portion 12. Steel balls are placed in the ball storage frame 1. Since the bottom surface 11 is inclined, the steel balls will automatically slide to the area where the lower portion 12 is located. An outlet 13 is provided on the ball storage frame 1. The outlet 13 is located on the wall of the ball storage frame 1, and the outlet 13 is connected to the lower portion 12, that is, the steel balls can go out from the outlet 13.

[0026] A chute 2 is arranged on the outside of the ball storage frame 1, and the inlet end of the chute 2 is connected to the outlet 13. The steel balls flowing out of the outlet 13 enter the chute 2. A screening hole 3 is arranged on the bottom surface of the chute 2. The width of the outlet 13 is greater than the width of the screening hole 3. In this way, if the diameter of the steel ball is greater than the width of the outlet 13, the steel ball will be clamped at the outlet 13, and then the steel ball with a large diameter will be taken away manually. The steel balls entering the chute 2 pass through the screening hole 3. If the diameter of the steel ball is greater than the width of the screening hole 3, it will continue to slide forward, and if the diameter of the steel ball is smaller than the screening hole 3, it will flow downward from the screening hole 3. In this way, the steel balls that have not flowed out of the screening hole 3 are collected from the outlet end of the chute 2.

[0027] The chute 2 is inclined downward from near to far, that is, the farther the chute 2 is from the ball storage frame 1, the closer it is to the ground. The bottom end of the upper part of the chute 2 is overlapped with the bottom end of the ball storage frame 1. The farther the chute 2 is from the ball storage frame 1, the lower its height. A support rod is provided at the bottom of the chute 2, which can speed up the sliding of the steel ball. The number of chute 2 settings is not limited.

[0028] There is a first slot 21 and a second slot 22 between the slide groove 2 and the ball storage frame 1, and a baffle 5 is movably arranged in the first slot 21 and the second slot 22. When the steel ball is not needed to slide from the outlet 13, the baffle 5 is clamped in the first slot 21 and the second slot 22. When the steel ball is needed to slide from the outlet 13, the baffle 5 is taken out.

[0029] The first notch 21 and the second notch 22 are V-shaped grooves, and the baffle 5 matches the V-shaped groove. The baffle 5 is a triangle, which is equivalent to embedding the triangular baffle 5 into the first notch 21 and the second notch 22. Because the slide groove 2 is obliquely overlapped at the bottom of the ball storage frame 1, the first notch 21 and the second notch 22 are naturally formed between the two walls of the slide groove 2 and the wall of the ball storage frame 1, and no additional grooves are required.

[0030] The screening hole 3 is rectangular, and there is a groove at the bottom of the chute 2 (not shown in the figure). The screening hole 3 is arranged in the groove. There is also a distance between the screening hole 3 and the two walls of the chute 2. The steel balls sliding down from the outlet 13 do not necessarily move in a straight line. The extension direction of the screening hole 3 is consistent with the extension direction of the chute 2, so these steel balls moving to the side will eventually return to the groove and pass through the screening hole 3. If the length of the screening hole 3 is too short, some steel balls will not pass through the screening hole 3.

[0031] A collecting box 4 is provided at the bottom of the chute 2, and the opening of the collecting box 4 is aligned with the screening hole 3. Steel balls with diameters smaller than the set size fall into the collecting box 4 and are then recycled. The collecting box 4 is detachably provided at the bottom of the chute 2.

[0032] A first vertical rod 23 and a second vertical rod 24 are provided at the outlet end of the chute 2. The first vertical rod 23 and the second vertical rod 24 are respectively located on the two side walls of the chute 2. Bags are sleeved on the first vertical rod 23 and the second vertical rod 24. The opening of the bag is aligned with the outlet end of the chute 2, so that the standard steel balls slide into the bags.

[0033] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
