DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0028] Example 1

[0029] See also Figure 1-3 This embodiment provides the following technical solution: a feeding device for abrasives, comprising a silo 1 and a main feed pipe 2 fixedly arranged at the bottom of the silo 1,

[0030] A plurality of branch discharge mechanisms 3 are also provided at the bottom of the silo 1. Each branch discharge mechanism 3 includes a branch discharge pipe 31, a connecting pipe 32 and a spiral conveying cylinder 33. The discharge pipe is connected to the connecting pipe 32. The connecting pipe 32 is connected to the feed port of the spiral conveying cylinder 33. A driving motor 34 is provided at one end of the spiral conveying cylinder 33. The abrasive discharged from the branch discharge pipe 31 can be conveyed through the spiral conveying cylinder 33, thereby improving the discharge efficiency of the abrasive.

[0031] In this embodiment, the discharge port of the spiral conveying cylinder 33 is arranged to be inclined downward.

[0032] The invention also includes a control system 4, which includes a control box 41. A controller is fixedly installed in the control box 41. A box door 42 is installed on the control box 41. A speed regulator 43, a start-stop switch 44 and a motor operation timer 45 corresponding to each drive motor 34 are installed on the box door 42. Through the feeding mechanism 3 and the control system 4, the added grinding material can be automatically measured during the process of adding grinding material to the grinding equipment, which is convenient for controlling the material level instead of manually measuring the material level. It is not only convenient to add the grinding material, but also improves the feeding efficiency of the grinding material.

[0033] The controller is electrically connected to the speed regulator 43 , the start / stop switch 44 , the motor operation timer 45 , and the drive motor 34 .

[0034] The branch discharge pipe 31 and the connecting pipe 32 are fixedly connected via a pipe clamp 6 , and the connecting pipe 32 can be easily assembled and disassembled from the branch discharge pipe 31 via the pipe clamp 6 .

[0035] A vibration motor 7 is fixedly connected to one side of the bottom of the silo 1. The vibration motor 7 prevents the grinding material from being blocked in the branch discharge pipe 31, thereby improving the efficiency of adding the grinding material into the grinding equipment.

[0036] The working principle of the utility model is as follows: when it is necessary to unload materials, the vibration motor 7 is started to vibrate the abrasive material at the bottom of the silo 1. At the same time, the speed of the drive motor 34 is preset by rotating the speed regulator, and then the working time of the drive motor 34 is preset by operating the motor operation timer 45. Finally, the start-stop switch 44 is pressed to make the corresponding drive motor 34 drive the spiral conveying drum 33 to rotate, so that the spiral conveying drum 33 conveys the abrasive material. When the motor operation timer 45 returns to zero, the drive motor 34 stops working, thereby stopping the feeding operation of the abrasive material.
