The quantity for grabbing ball element 132 is unlimited, and in the present embodiment, the quantity for grabbing ball element 132 is four, and four are grabbed ball element 132 Axis around motorized roller 131 is uniformly distributed in the shape of a spiral.
Please refer to shown in Fig. 7, each grab ball element 132 include at least three be arranged side by side grab ball fingerboard 133, grab ball element 132 top is provided with for accommodating the holding tank to abrading-ball.
In addition, optionally, each grabbing ball element 132 and grabbing ball fingerboard 133 including three.
It please refers to shown in Fig. 8, that grabs ball fingerboard 133 is provided with V-notch 137 to the side of abrading-ball for carrying, and three The V-notch 137 for grabbing ball fingerboard 133 forms holding tank.
Wherein, it is the first fingerboard and two the second fingerboards that three, which are grabbed 133 points of ball fingerboard, and two the second fingerboards are located at The two sides of one fingerboard.
The depth of first fingerboard V-notch 137 is greater than the depth of the second fingerboard V-notch 137, the first fingerboard V-notch 137 width is greater than the width of the second fingerboard V-notch 137.
It grabs ball fingerboard 133 to shift to install with comb teeth 134, so as to grab 133 energy of ball fingerboard in 131 rotation process of motorized roller It is enough from bottom to enter combing channel and by grabbing to abrading-ball to holding tank on dressing bottom plate 130.
Dressing bottom plate 130 and release part 15 are located at the two sides of motorized roller 131, so that grabbing ball element 132 can be with The rotation of motorized roller 131 will be transported to from dressing bottom plate 130 in ball channel to abrading-ball.
Release part 15 has for ball channel, is arranged for ball channel slopes, it is adjacent with selector 13 for the one end in ball channel and For receive the conveying of selector 13 to abrading-ball, for ball channel the other end be used for it is adjacent with ball mill and can will be defeated to abrading-ball It send to ball mill.
In addition, being also provided with photoelectric detector 138 in release part 15, photoelectric detector 138 is logical for ball for detecting In road to abrading-ball for ball speed and control motorized roller 131 revolving speed.
When for when being greater than the first preset threshold for ball speed, photoelectric detector 138 controls motorized roller 131 in ball channel Revolving speed reduces, and when for ball speed less than the second preset threshold, photoelectric detector 138 controls 131 revolving speed of motorized roller and increases.
Wherein, the first preset threshold is greater than the second preset threshold, is in a period for ball quantity for ball speed.
It is fallen to abrading-ball in specified location for the ease of control, grabs specifically connecting between ball element 132 and motorized roller 131 Connect relationship are as follows: grab and connect between ball element 132 and motorized roller 131 by collets.
It please refers to shown in Fig. 9, selector 13 further includes controller and multiple suction ball components 141, suction ball component 141 and grabs ball Part 132 corresponds.
Suction ball component 141 includes power supply 142, conductive winding 143 and resistance 144.
Conductive winding 143 is set around at least one and grabs ball fingerboard 133, grabs ball fingerboard 133 and is made of silicon steel material, conductive The both ends of winding 143 are electrically connected with the anode and cathode of power supply 142 respectively by 142 line of power supply, and resistance 144 is set to power supply On 142 lines.
Electromagnet is collectively formed with ball fingerboard 133 is grabbed in suction ball component 141, and controller is for controlling each suction ball component 141 Power supply 142 open or close.
When grabbing ball element 132 and turning to the first designated position, grabs ball fingerboard 133 and forms electromagnet and for adsorbing to abrading-ball, When grabbing ball element 132 and turning to the second designated position, power supply 142 closes and falls off and fall into for ball in ball element 132 from grabbing to abrading-ball In channel.
It should be noted that above-mentioned electromagnet structure, is only applicable to when abrading-ball is the metal material that can be adsorbed It uses.
Ball adding mechanism 10 provided by the invention, including bracket 11, ball storehouse 12, selector 13 and release part 15, selector 13 Including dressing bottom plate 130, motorized roller 131 and ball element 132 is grabbed, dressing bottom plate 130 has multiple comb teeth 134 arranged side by side, Combing channel is formed between two adjacent comb teeth 134;Grab ball element 132 include at least three be arranged side by side grab ball fingerboard 133, It grabs ball fingerboard 133 to shift to install with comb teeth 134, is used to grab that ball element 132 grabs is delivered to ball mill to abrading-ball for ball channel It is interior.
It will be put into abrading-ball in ball storehouse 12, and fall to dressing bottom plate to abrading-ball outlet under gravity to abrading-ball On 130, motorized roller 131, which is rotated and driven, grabs the rotation of ball element 132, grabs ball element 132 and enters in combing channel and grab from bottom It is corresponding to abrading-ball, as motorized roller 131 rotates, grab ball element 132 and turn to and will pour into abrading-ball in ball channel, to abrading-ball Enter in ball mill via for ball channel.
The ball adding mechanism 10 and milling system structure of this structure are simple, easy to use, and manufacturing cost is lower, and comb teeth 134 are effectively reduced the maximum height for grabbing ball element 132 with the structure for grabbing ball fingerboard 133, can fall into avoid to abrading-ball for ball It is impacted caused by when in channel, effective protection is for ball channel.
Corresponding, the embodiment of the invention also provides a kind of milling system, which includes ball mill and above-mentioned reality Apply the ball adding mechanism 10 in example.
