Referring to fig. 1 to 3, in the preferred embodiment of the present invention, the ball sorting apparatus 10 includes a frame 100, a feeding hopper 200, a vibration dust removing mechanism 300 and a sorting mechanism 400;

the rack 100 has a first end 110 and a second end 120 in the horizontal direction. Thus, the direction in which the first end 110 points toward the second end 120 is a horizontal direction. The frame 100 mainly serves as a support and a connection.

A feed hopper 200 is mounted to first end 110. During the use of the grinding ball sorting device 10, the grinding ball materials can be conveyed into the feed hopper 200 and continuously fed through the feed hopper 200, so that the working continuity of the grinding ball sorting device 10 is ensured.

Referring to fig. 4 and 5, the vibration dust removing mechanism 300 includes a vibrator 310 and a dust removing conveying trough 320. The dust removal conveying trough 320 is installed at the first end 110 and is located below the discharge port of the feed hopper 200. Thus, the grinding ball material in the feed hopper 200 can directly drop into the dust removal conveying groove 320 under the action of its own weight. Specifically, the discharge port of the feed hopper 200 is vertically aligned with the inlet port of the dust removal conveying chute 320 to ensure that all of the ball material discharged from the discharge port of the feed hopper 200 can enter the dust removal conveying chute 320. The bottom of the dust removing conveying groove 320 is provided with a plurality of dust outlet holes 321 at intervals. The vibrator 310 may be an electromagnetic vibrator 310, or may be a mechanical vibration mechanism.

Referring also to fig. 6, the sorting mechanism 400 is mounted to the second end 120. The sorting mechanism 400 includes a plurality of sorting rollers 410 and a sorting drive 420. Each sorting drum 410 is a cylindrical structure with both ends open. The plurality of sorting drums 410 are in serial communication along a direction from the first end 110 toward the second end 120. A plurality of sorting holes 411 are formed at intervals in the sidewall of each sorting drum 410. The sorting drive 420 is used to drive the plurality of sorting drums 410 to rotate to transport the ball material currently in the sorting drum 410 to the next sorting drum 410. Thus, the vibratory drive 313 can simultaneously drive the plurality of sorting drums 410 to rotate simultaneously, and move the ball material entering the sorting drums 410 from the dust removal conveying chute 320 in a direction in which the first end 110 points to the second end 120, and sequentially pass through the plurality of sorting drums 410.

The vibrator 310 is used to provide a vibrating force for driving the dust removing conveying groove 320 to vibrate in the horizontal direction and the vertical direction to convey the ball materials received from the feed hopper 200 into the adjacent sorting drum 410. In the actual use process, the vibrator 310 can drive the dust removal conveying groove 320 to vibrate in the horizontal direction and the vertical direction so as to shake down impurities such as dust on the grinding ball materials in the dust removal conveying groove 320 and screen out the shaken impurities such as dust from the dust outlet hole 321, thereby realizing the dust removal of the grinding ball materials; the ball material after dust removal moves to the separation roller 410 adjacent to the dust removal conveying groove 320 along with the vibration of the dust removal conveying groove 320, so that the function of conveying the material to the separation mechanism 400 is realized.

The aperture of the dust outlet hole 321 is smaller than that of any one of the sorting holes 411. So, can guarantee out dust hole 321 when screening out impurity such as dust, avoid the condition emergence that the ball in the ball material was screened out to obtain more qualified balls in follow-up sorting process, improve the ball and select separately the effect.

The aperture of the sorting holes 411 in the plurality of sorting drums 410 increases in order in the direction in which the first end 110 points toward the second end 120. Thus, when the grinding ball materials move in the plurality of sorting rollers 410 along the direction from the first end 110 to the second end 120, under the driving force provided by the vibration driving member 313, the multi-stage sorting of the grinding ball materials can be realized, so that grinding balls with various sizes can be obtained simultaneously.

From this, before selecting separately, utilize vibration dust removal mechanism 300 to remove dust to the ball material to make the ball material cleaner, with the factor that reduces the influence ball sorting result, obtain accurate sorting result, further improve ball sorting effect. Moreover, the vibration driving member 313 drives the sorting rollers 410 to rotate simultaneously, so that grinding balls with various sizes and specifications can be automatically sorted simultaneously, and the grinding ball sorting efficiency is improved. Therefore, the above-described grinding ball sorting apparatus 10 gives consideration to both a high grinding ball sorting effect and a high grinding ball sorting efficiency.

In some embodiments, on each sorting drum 410, a plurality of sorting holes 411 are evenly distributed on the sidewall of the sorting drum 410. Specifically, the plurality of sorting holes 411 are distributed in a matrix on the side wall of the sorting drum 410. When the sorting drum 410 rotates, the grinding ball materials in the sorting drum 410 are subjected to centrifugal force, so that the grinding balls which can pass through the corresponding sorting holes 411 are thrown out, and sorting of the grinding ball materials is realized. The evenly distributed sorting holes 411 can ensure the discharging uniformity when more grinding ball materials are in the sorting roller 410, and reduce the probability of material blockage.

Referring again to fig. 6, in some embodiments, each sorting hole 411 is an elongated through hole formed along the circumferential direction of the sorting drum 410. The aperture of the dust outlet hole 321 is smaller than the width of any one of the sorting holes 411. Note that the width of the sorting hole 411 refers to the aperture diameter of the sorting hole 411 in the axial direction of the sorting drum 410. And to select separately hole 411 and set up to along selecting separately ascending rectangular shape through-hole of cylinder 410 circumference, can improve and select separately cylinder 410 and rotate the in-process, the probability that the ball material was thrown away from selecting separately in hole 411 to can sort out more balls when improving ball sorting speed, make ball sorting effect and ball sorting efficiency higher.

Referring again to fig. 3, in some embodiments, a plurality of sorting rollers 410 are disposed coaxially. The central axis of each sorting drum 410 is disposed obliquely downward with respect to the horizontal direction in which the first end 110 points toward the second end 120. Therefore, each sorting roller 410 is obliquely and downwards arranged along the direction that the first end 110 points to the second end 120, at the moment, the grinding ball materials in the sorting roller 410 have a tendency of moving from the first end 110 to the second end 120 under the action of self gravity, and meanwhile, the rotation of the sorting roller 410 is matched to ensure that the process that the grinding ball materials in the sorting roller 410 move from the first end 110 to the second end 120 is smoother and quicker, and the grinding ball sorting efficiency is further improved.

In some embodiments, the extension direction of the dust removal conveying groove 320 is set obliquely downward with respect to the horizontal direction in which the first end 110 is directed toward the second end 120. So, the material direction of delivery of dust removal conveyer trough 320 sets up downwards along the direction slope of the directional second end 120 of first end 110, the ball material in the conveyer trough 320 that removes dust this moment will have one under self action of gravity to order about to the adjacent sorting roller 410 removal of conveyer trough 320 that removes dust, the vibration effect of the conveyer trough 320 that removes dust simultaneously coordinates, in order to carry the ball material in the conveyer trough 320 that removes dust fast to adjacent sorting roller 410, be favorable to further improvement of ball sorting speed, the ball sorting efficiency has further been improved.

Referring to fig. 4 and 5 again, in some embodiments, the vibration dust removing mechanism 300 further includes a plurality of connecting swing rods 330 spaced along the circumferential direction of the dust removing conveying groove 320. Two ends of each connecting swing rod 330 are respectively rotatably connected with the dust removing conveying groove 320 and the rack 100, so that the dust removing conveying groove 320 is arranged below the feeding hopper 200 in a suspended manner. Specifically. One end of each link swing link 330, which is far away from the dust removing conveyer trough 320, is movably installed at the top of the frame 100 to suspend the dust removing conveyer trough 320 below the feed hopper 200. Thus, the dust removing conveying groove 320 is vibrated in the horizontal direction and the vertical direction by the vibration force provided by the vibrator 310, and the connection swing link 330 is swung along with the dust removing conveying groove 320. In this way, the arrangement of the connecting swing link 330 makes the installation of the dust removing conveying groove 320 on the frame 100 more convenient.

Further, in some embodiments, the vibrator 310 includes a connecting rod 311, an eccentric 312 rotatably disposed at one end of the connecting rod 311, and a vibration driving member 313. One end of the connecting rod 311 far away from the eccentric wheel 312 is movably connected with the dust removing conveying groove 320. The eccentric wheel 312 is provided with an eccentric hole 3121. The central axis of the eccentric hole 3121 is spaced apart from the central axis of the eccentric wheel 312. In this manner, the eccentric hole 3121 is eccentrically disposed with respect to the central axis of the eccentric wheel 312. The output shaft 3131 of the vibration driving member 313 is inserted into the eccentric hole 3121, and is in transmission connection with the eccentric wheel 312. The vibration driving member 313 may be a hydraulic motor, a servo motor, or the like.

Therefore, the connecting rod 311, the eccentric wheel 312 and the vibration driving member 313 can form an eccentric vibration mechanism, when in use, the output shaft 3131 of the vibration driving member 313 drives the eccentric wheel 312 to rotate at a high speed, and at this time, the eccentric wheel 312 can drive the connecting rod 311 to eccentrically swing around the output shaft 3131 of the vibration driving member 313, so as to drive the dust removing conveying trough 320 to vibrate in the horizontal direction and the vertical direction.

Referring again to fig. 1-3, in some embodiments, the ball sorting apparatus 10 further includes a dust collection bin 510 and a first receiving bin 520. The dust collecting hopper 510 is installed on the frame 100 and located below the dust-removing conveying groove 320, and is used for collecting dust flowing out of all the dust outlet holes 321. The first receiving tub 520 is disposed under the dust collecting body 510 and receives dust flowing down the dust collecting body 510.

From this, in the in-service use process, after impurity such as dust in the ball material was sieved out through dust outlet 321 under the vibrating force effect that dust removal conveyer trough 320 provided at vibrator 310, dust is collected and is fought 510 and can collect all impurity such as dust sieved out from dust removal conveyer trough 320, and collect these impurity in carrying to first receiving bucket 520, reduce impurity such as dust and spill around the equipment among the ball sorting process, influence the condition of production environment and take place, and the work of sweeping the tail end after the ball sorting work has still been simplified.

In some embodiments, the ball sorting apparatus 10 further includes a material guide chute 610 and a plurality of second material receiving buckets 620. The plurality of guide chutes 610 correspond to the plurality of sorting drums 410 one to one, respectively. Each guide chute 610 is mounted to the frame 100 and positioned below the corresponding sorting drum 410 to collect the ball material sorted through the sorting holes 411 of the corresponding sorting drum 410. Each guide chute 610 is arranged obliquely downwards in a direction away from the corresponding sorting drum 410 and is used for conveying the collected grinding ball materials into the corresponding second receiving bucket 620.

Therefore, a material guide groove 610 is arranged below each sorting roller 410, and a second material receiving barrel 620 is arranged below the material guide groove 610, so that the grinding balls sorted by each sorting roller 410 in the rotating process can be collected, and sorted grinding balls with different sizes and specifications can be conveniently classified and stored in the subsequent process.

In some embodiments, the ball sorting apparatus 10 further includes a waste hopper 710 and a waste bin 720. A waste hopper 710 is mounted to the second end 120 and is located on a side of the sorting mechanism 400 facing away from the vibratory dust removal mechanism 300 for collecting the grinding ball waste material flowing from the port of the outermost sorting drum 410. Waste bin 720 is disposed below waste bin 710 and is configured to receive the grinding ball waste material flowing from waste bin 710.

The outermost sorting drum 410 refers to the sorting drum 410 that is the farthest from the vibratory dust removing mechanism 300 among the plurality of sorting drums 410; the end port of the outermost sorting drum 410 means an opening of an end of the outermost sorting drum 410 facing away from the dust-removing vibration mechanism.

In practical application, after the grinding ball materials are subjected to multi-stage sorting by the plurality of sorting drums 410, some grinding ball materials which do not conform to the sorting condition inevitably exist as grinding ball waste materials, and are discharged from the port of the last sorting drum 410, and at this time, the waste hopper 710 can guide all the grinding ball waste materials into the waste barrel 720 so as to facilitate the collection and subsequent treatment of the grinding ball waste materials.
