The upper side of the first rotating shaft is connected to the lower left side of the conveyor belt. An internally threaded sleeve is connected to the middle side wall of the second rotating shaft. An adjusting rod is threadedly connected to the internally threaded sleeve. The upper end of the adjusting rod is rotatably connected to a third rotating shaft through a bearing. Both ends of the third rotating shaft are rotatably connected to the lower right side of the conveyor belt through bearings.

[0010] Preferably, an adjusting turntable is fixedly connected to the bottom end of the adjusting rod.

[0011] Preferably, retaining bars are provided at the front and rear edges of the conveyor belt, and the retaining bars extend to the left and right ends of the conveyor belt.

[0012] Preferably, a horizontal support plate is provided inside the vertical carrier. The horizontal support plate is located below the lower opening of the storage bin.

[0015] Compared with the prior art, the beneficial effects of the present invention are: During use, the steel balls to be screened are concentrated in the feed bin and fall onto the conveyor belt under the action of gravity. Due to the set angle of the conveyor belt, the steel balls with a smooth surface can roll towards the lower left side under the action of gravity, while the steel balls with surface defects such as missing pieces or protruding grains on the surface of the steel balls will hinder the rolling of the steel balls, causing the steel balls to stay on the surface of the conveyor belt and thus be transported to the right as the conveyor belt moves, realizing the separation of qualified steel balls and defective steel balls, and entering the material guiding channel, the good product receiving cart and the defective product receiving box respectively.

[0016] Based on the above screening method, the overall efficiency is high, and it can effectively separate qualified steel balls and defective steel balls, reducing the use of labor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is 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 should not be construed as a limitation to the present invention.

[0021] Example 1. Please refer to Figures 1-4 , the present invention provides a technical solution: a steel ball screening machine, including: a horizontal carrier 1, a vertical carrier 2, a material bin 17, a conveyor belt 4, a guiding channel 5, a qualified product receiving cart 6 and a defective product receiving box 7; Among them, the vertical carrier 2 is installed on the upper middle side of the horizontal carrier 1, the conveyor belt 4 is installed inside the horizontal carrier 1, and the conveyor belt 4 is arranged in an inclined shape with the left side lower and the right side higher, and the conveyor belt 4 conveys from left to right; the guiding channel 5 and the defective product receiving box 7 are respectively installed on the left and right sides of the horizontal carrier 1, and the guiding channel 5 is located on the lower left side of the conveyor belt 4, the defective product receiving box 7 is located on the lower right side of the conveyor belt 4, and the qualified product receiving cart 6 corresponds to the outlet position of the guiding channel 5; the material bin 17 is hollow and has an opening at the lower part, the material bin 17 is installed at the top of the vertical carrier 2, and the lower opening of the material bin 17 corresponds to the position of the conveyor belt 4.

[0022] Analysis of the above content: When in use, place the horizontal carrier 1 on a flat ground to make the overall equipment stably installed. Fill the material bin 17 with steel balls to be screened in advance, set a valve at the lower opening of the material bin 17. When screening is required, open the valve, and the steel balls fall under the action of gravity. When the screening is over or screening is not required, close the valve so that the steel balls in the material bin 17 no longer fall.

[0023] The falling steel balls land on the conveyor belt 4, and at the same time the conveyor belt 4 operates. Since the conveyor belt 4 is in an inclined shape with the left side lower and the right side higher as a whole, the qualified spherical steel balls roll to the lower left side, and the steel balls with incomplete and uneven surfaces are blocked and stay on the surface of the conveyor belt 4 and move to the right as the conveyor belt 4 conveys. Finally, the qualified steel balls enter the guiding channel 5, and the defective steel balls enter the defective product receiving box 7.

[0024] The guiding channel 5 is set in an inclined shape with the rear higher and the front lower, so that the guiding channel 5 can guide the qualified steel balls forward and into the qualified product receiving cart 6 on the front side. Subsequently, take out the defective steel balls in the defective product receiving box 7 for centralized processing.

[0025] Example 2. Please refer to Figures 1-4 , based on Example 1, the present invention provides a technical solution: both the horizontal carrier 1 and the vertical carrier 2 are welded from carbon steel structures, and the surfaces of the horizontal carrier 1 and the vertical carrier 2 are painted.

[0026] Analysis of the above content: As Figure 1 shown, the horizontal carrier 1 and the vertical carrier 2 are steel frames welded according to the dimensions of components such as the material bin 17, the conveyor belt 4, and the guiding channel 5.

[0027] Example 3. Please refer toFigures 1-4 The present invention provides a technical solution based on the first embodiment: the four corners and the middle of the lower surface of the transverse support frame 1 are longitudinally threaded with screw rods 9, and the bottom end of the screw rod 9 is provided with a supporting foot 10. The four corners of the lower surface of the transverse support frame 1 are provided with rollers 8.

[0028] Analysis of the above content: When it needs to move, the roller 8 contacts the ground and pushes the device as a whole. Based on the movement of the roller 8, the roller 8 can be set as a universal wheel, which can move the device to a suitable position. After moving to a suitable position, the screw 9 is rotated, and the screw 9 moves downward relative to the horizontal support frame 1 through threaded cooperation until the support foot 10 touches the ground and the roller 8 is separated from the ground. Then, multiple screws 9 and support feet 10 are adjusted to make the whole stable and avoid some support feet 10 not touching the ground.

[0029] Example 4, please refer to Figures 1-4 The present invention provides a technical solution based on the first embodiment: the left and right sides of the upper surface of the horizontal carrier 1 are rotatably connected with a first shaft 18 and a second shaft 20 through bearings, the upper side of the first shaft 18 is connected to the lower left side of the conveyor belt 4, the middle side wall of the second shaft 20 is connected with an internal thread sleeve, the internal thread sleeve is internally threaded with an adjustment rod 21, the upper end of the adjustment rod 21 is rotatably connected with a third shaft 19 through a bearing, and the two ends of the third shaft 19 are rotatably connected with the lower right side of the conveyor belt 4 through bearings. The bottom end of the adjustment rod 21 is fixedly connected with an adjustment dial.

[0030] Analysis of the above content: Figure 1 , 4 As shown, the rotating shaft 18 and the rotating shaft 20 are located on the transverse carrier frame 1, and can only rotate relative to the transverse carrier frame 1, but cannot be separated from the transverse carrier frame 1. When the adjusting rod 21 is rotated, the adjusting rod 21 cooperates with the thread of the internal threaded sleeve to make the upper end of the adjusting rod 21 move up or down, thereby pushing the conveyor belt 4 to rotate relative to the transverse carrier frame 1 based on the rotating shaft 18. At this time, the right end of the conveyor belt 4 is lifted up or lowered. Since the upper end of the adjusting rod 21 is connected to the outer wall of the rotating shaft 3 19 through the bearing, when the adjusting rod 21 rotates, it does not affect the rotation of the rotating shaft 3 19 on the bearing.

[0031] The rotating shaft 18 and the rotating shaft 3 19 are connected to the outer shell or the side plate of the conveyor belt 4 (here, according to the specific structural form of the conveyor belt 4, the setting of the rotating shaft 18 and the rotating shaft 3 19 does not affect the normal transmission function of the conveyor belt 4).

[0032] For example 5, please refer to Figures 1-4 The present invention provides a technical solution based on the first embodiment: the front and rear side edges of the conveyor belt 4 are both provided with a material blocking strip 11, and the material blocking strip 11 extends to the left and right sides to the left and right ends of the conveyor belt 4.

[0033] Analysis of the above content: The baffle strip 11 blocks the steel balls on the conveyor belt 4 from the front and back sides, preventing the steel balls on it from detaching from the conveyor belt 4.

[0034] Example Six. Please refer to Figures 1-4 , the present invention provides a technical solution based on Example One: A horizontal support plate 3 is provided inside the longitudinal support frame 2. The horizontal support plate 3 is located below the lower opening of the bin 17. A receiving box 12 is provided on the horizontal support plate 3. The receiving box 12 is located directly below the lower opening of the bin 17. An inclined guide plate 13 is provided on the lower right side of the receiving box 12. The inclined guide plate 13 is trapezoidal with a smaller left side and a larger right side.

[0035] Analysis of the above content: The bin 17 discharges the steel balls onto the receiving box 12, and then they enter the inclined guide plate 13 and are dispersed onto the conveyor belt 4 based on the inclined guide plate 13, avoiding the situation where the steel balls bounce out of the conveyor belt 4 when they directly fall on the conveyor belt 4.

[0036] Example Seven. Please refer to Figures 1-4 , the present invention provides a technical solution based on Example Six: A vibration mechanism 16 is installed on the upper surface of the horizontal support plate 3. The receiving box 12 is fixedly installed at the vibrating end of the vibration mechanism 16.

[0037] Analysis of the above content: The setting of the vibration mechanism 16 disperses the steel balls on the receiving box 12, avoiding concentration, and can promote the movement of the steel balls on the receiving box 12, preventing the steel balls from staying on the receiving box 12 without falling.

[0038] Example Eight. Please refer to Figures 1-4 , the present invention provides a technical solution based on Example Six or Example Seven: Two connection holes 14 are provided on the lower right side of the receiving box 12. The left upper end of the inclined guide plate 13 is rotatably connected to one of the connection holes 14 through a pin shaft. An arc-shaped groove 15 corresponding to the position of the other connection hole 14 is opened on the upper left side of the inclined guide plate 13. The other connection hole 14 is within the range of the arc-shaped groove 15. A fastening bolt is screwed into the other connection hole 14. Based on the cooperation of the arc-shaped groove 15 and the two connection holes 14, the inclined guide plate 13 can adjust its angle within the limit range of the arc-shaped groove 15, and then the receiving box 12 and the inclined guide plate 13 are fastened through the bolt.

[0039] Analysis of the above content: The inclined guide plate 13 can rotate relative to the receiving box 12 through the pin shaft on the left side, thereby adjusting the angle of the inclined guide plate 13. By using the cooperation of the arc-shaped groove 15 and the fastening bolt, the rotation angle of the inclined guide plate 13 is restricted. After adjusting to the appropriate angle, the fastening bolt is tightened to fasten the receiving box 12 and the inclined guide plate 13.
