[0027] Embodiment 1

[0028] In order to solve the problems of large labor intensity caused by continuously feeding steel balls to the screening machine by hand and the need to clean the surface of the steel balls so that surface impurities do not affect the screening effect of the steel balls, please refer to Figures 1-4The steel ball screening and feeding machine can uniformly convey the steel balls, so that the labor intensity of manual work is reduced, and the surface of the steel ball is cleaned during conveying, so that the surface of the steel ball does not adhere to excess impurities, thereby reducing the influence of the impurities on the surface of the steel ball on the screening accuracy, improving the screening effect and work efficiency of the steel ball. The feeding machine comprises a base 1 located in a processing area and a rotating groove 11 arranged thereon, and the base 1 is provided with a working assembly 2 for conveying and cleaning the steel balls, and the base 1 is used for supporting the working assembly 2. The working assembly 2 comprises a support table 21 rotatably installed on the base 1, the support table 21 is used for connecting the feeding rack 22 and the base 1, and supporting the components installed thereon. The depth of the rotating groove 11 is greater than the depth required by the rotating angle of the support table 21, so that the rotating groove 11 is not blocked when the conveying angle is adjusted. The support table 21 is fixedly connected with the feeding rack 22 extending out of the rotating groove 11, and the feeding rack 22 is used for supporting the internal structure and limiting the conveying path of the steel balls. The feeding rack 22 is provided with an inner cavity, and the feeding rack 22 is rotatably connected with a rotating shaft 23, and the rotating shaft 23 is fixedly connected with a rotating blade 24 in a spiral shape, and the rotating blade 24 is used for conveying the steel balls. The inner cavity is formed with a first processing interval 25, a second processing interval 26 and a third processing interval 27 for different cleaning processing of the steel balls, and the support table 21 is fixedly installed with a reducer 28 fixedly connected with the rotating shaft 23, and the reducer 28 is used for reducing the rotating speed of the input shaft of the first motor 29 and increasing the output torque at the same time. The support table 21 is also fixedly installed with a first motor 29 for driving the rotating shaft 23 to rotate, and the first motor 29 serves as a power source for conveying the steel balls. The feeding rack 22 is fixedly connected with an inlet communicated with the inner cavity, and the inner wall of the inlet is fixedly connected with a soft material such as rubber pad to reduce the damage to the outer surface of the steel ball caused by hard material. The feeding rack 22 is also provided with an outlet communicated with the inner cavity, and the outlet is located on one side of the end portion of the rotating blade 24. The working assembly 2 is provided below with a pushing assembly 3 for vertically pushing and sliding the working assembly 2. When conveying the steel balls, the feeding machine is pushed to the appropriate position of the steel balls and the screening machine, the angle and height of the feeding machine are adjusted through the pushing assembly 3, so that the outlet can accurately align the screening machine, and the steel balls can be conveyed into the screening machine. Then the first motor 29 is started, and the rotating shaft 23 drives the rotating blade 24 to rotate under the action of the reducer 28, and then the steel balls are placed in the inlet, and the steel balls are driven by the rotating blade 24 to pass through the first processing interval 25, the second processing interval 26 and the third processing interval 27 for different cleaning processing, and then enter the screening machine through the outlet for screening, so that the steel balls are uniformly conveyed into the screening machine, and the surface of the steel ball is cleaned during conveying, so that the adhering matter on the surface of the steel ball does not block the screen of the screening machine, thereby improving the screening effect and work efficiency of the steel ball.

[0029] It is considered that dust, iron filings and even oil stains and other impurities on the surface of the steel ball are easily attached, and the impurities on the surface need to be cleaned so as not to block the screen during screening. Referring to Figures 1-4 , a plurality of sliding grooves 251 are symmetrically and irregularly arranged on the inner wall of the feeding frame 22 in the first processing interval 25, and the sliding grooves 251 are used to install the brush plate 252. The sliding grooves 251 are arranged along the transmission direction of the rotating leaves 24. The brush plate 252 is slidably connected in the sliding groove 251, and a plurality of brush strips 253 uniformly distributed horizontally and vertically are fixedly connected to the brush plate 252. The brush strips 253 are used to brush the surface of the steel ball, and the brush strips 253 are made of soft and elastic material, which will not cause damage to the surface of the steel ball during brushing. The spring 254 is fixedly connected between the brush plate 252 and the sliding groove 251, and the spring 254 is used to limit the brush plate 252, so that the brush plate 252 is retracted by a part under the pushing force when the rotating leaf 24 contacts the brush, so that the rotating leaf 24 is not affected. The brush plate 252 is located in the groove formed between the rotating leaves 24, and the end of the brush strip 253 is attached to the surface of the rotating shaft 23, so that the brush strip 253 can be attached to the surface of the steel ball when the rotating leaf 24 drives the transmission of the steel ball, and the brush strip 253 can be brushed. A plurality of first installation grooves 261 are arranged on the top end of the inner wall and both sides of the inner wall of the feeding frame 22 in the second processing interval 26, and the first installation grooves 261 are used to install the water spraying head 262. The first installation grooves 261 are arranged along the transmission direction of the rotating leaves 24, and the water spraying head 262 is fixedly connected in the first installation groove 261. The water spraying head 262 is used to spray water to the surface of the steel ball to be cleaned, and to wash the surface of the steel ball. The water spraying head 262 is flush with the surface of the inner wall of the feeding frame 22, so that the water spraying head 262 will not be damaged when the steel ball is transmitted. The water pump 263 connected with the water spraying head 262 is fixedly installed on the support table 21, and the water pump 263 is used as a power source for delivering water source to the water spraying head 262 for washing the steel ball. Before transmission, the water pump 263 is connected with the water source, and chemical products acting on the surface of the steel ball can be added in the water source to increase the decontamination of the surface of the steel ball and the maintenance of the surface thereof. When the steel ball enters the feeding frame 22 and rolls in the feeding frame 22 under the driving of the rotating leaf 24, the brush strip 253 is attached to the surface of the steel ball when the steel ball enters the first processing interval 25, and the brush strip 253 is brushed on the surface of the steel ball under the driving of the rotating leaf 24 and the rolling of the steel ball, so that the dust and iron filings attached to the surface of the steel ball fall off the surface of the steel ball. Then the steel ball enters the second processing interval 26, and the water pump 263 is started to deliver the water source to the water spraying head 262 for spraying, so as to wash the surface of the steel ball and prevent oil stains from being attached to the surface thereof. Thus, the impurities attached to the surface of the steel ball during screening will not be attached to the screen, the blockage of the screen and the damage of the surface impurities to the surface of the steel ball caused by friction during screening are reduced, and the effect and working efficiency of the steel ball screening are improved.

[0030] In order to remove the water on the surface of the steel ball after washing, so that the steel ball is dry and will not be affected, see Figures 1-2 A plurality of second installation grooves 271 are arranged on the top end of the inner wall of the feeding frame 22 in the third processing interval 27, and the second installation grooves 271 are used to install heating shafts 272. The second installation grooves 271 are arranged along the transmission direction of the rotating leaves 24, and the heating shafts 272 are fixedly installed in the second installation grooves 271. The heating shafts 272 are used to remove the water attached to the surface of the steel ball, and the heating mode can be various, such as electric heating. The filter plate 273 is fixedly connected to the top end of the inner wall of the feeding frame 22, and the filter plate 273 is used to protect the heating shafts 272 so that the steel ball will not collide with the heating shafts 272, thereby improving the safety of the heating shafts 272 during use. A plurality of filter holes are uniformly distributed on the filter plate 273, and the filter holes are smaller than the size of the processed steel ball, so as to ensure that the steel ball will not enter the second installation grooves 271. The filter plate 273 is located directly below the heating shafts 272 and is flush with the surface of the top end of the inner wall of the feeding frame 22. When the steel ball enters the second processing interval 26, the heating shafts 272 start to work at this time, and the temperature of the third processing interval 27 is increased under the action of the heating shafts 272. When the steel ball enters the third processing interval 27, the water on the surface of the steel ball is evaporated, so that the steel ball is dry, thereby reducing the influence of the water on the steel ball after washing.

[0031] Considering that the heights of different screening machines are different, the discharge port of the feeding machine needs to be adjusted to a suitable position with the screening, so that the cleaned steel balls can be directly conveyed to the screening machine for screening, see Figures 1-4 The pushing assembly 3 comprises a connecting table 31 arranged below the end of the feeding frame 22, and the connecting table 31 serves as a support platform. A worm 32 is rotatably installed in the connecting table 31, and the worm 32 is used to drive the worm 32. The symmetrical worm gears 33 are engaged with the worm 32, and the worm gears 33 are rotatably installed in the connecting table 31. The screw rod 34 is threadedly connected in the connecting table 31, and the end of the screw rod 34 is fixedly connected to the feeding frame 22. The screw rod 34 is used to push the feeding frame 22. The second motor 35 is fixedly installed on the connecting table 31 and drives the worm 32 to rotate. The second motor 35 serves as a power source for adjusting the height of the feeding frame 22. When the feeding machine is used, the feeding machine is first pushed to a suitable position with the steel ball and the screening machine, and then the second motor 35 is started. Under the action of the second motor 35, the worm 32 drives the worm gear 33 to rotate, and when the worm gear 33 rotates, the screw rod 34 threadedly connected in the worm gear 33 can rise, thereby adjusting the height and angle of the feeding frame 22. The cleaned steel balls cleaned by the working assembly 2 can be directly conveyed to the screening machine for screening, thereby reducing the need for rehandling, reducing the pollution of the steel balls during rehandling, reducing the labor intensity, and improving the working efficiency of the steel ball screening.

[0032] Embodiment 2

[0033] On the basis of embodiment 1, considering that the steel ball mainly rubs with the bottom end of the inner wall of the feeding frame 22 in the process of conveying, reducing the friction between them can improve the damage to the steel ball in conveying, referring to Figures 1-2 A plurality of rolling shafts 4 are rotatably installed in the feeding frame 22, the rolling shafts 4 are located below the rotating shaft 23, and the gap between the rolling shafts 4 is smaller than the size of the processed steel ball, so as to ensure that the steel ball will not fall off. By reducing the contact surface between the steel ball and the bottom end of the inner wall of the feeding frame 22 through the rolling shaft 4, the friction between them is reduced, the power consumption of the first motor 29 and the noise during conveying are reduced.

[0034] Considering that the impurities after cleaning the steel ball are easy to fall everywhere, the generated wastewater is not easy to clean, and the working environment is affected, and manual cleaning is required, referring to Figures 1-2 A collecting plate 5 is detachably installed below the feeding frame 22, and the collecting plate 5 is located directly below the rolling shaft 4. By collecting the impurities and wastewater after cleaning through the collecting plate 5, the impurities will not fall everywhere, and the wastewater will not be splashed onto the ground of the processing area, so that manual cleaning and cleaning after processing are not required, the labor intensity is reduced, and the working environment is improved.
