Abstract
Description
Technical Field
[0001] The utility model relates to the field of grinders, in particular to a dust collecting type grinder. Background Art
[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones, abrasive belts, and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders, and polishers.
[0003] When existing grinders are used, they are usually ground directly, which causes waste chips to fly and makes subsequent cleaning complicated. Although some grinders are equipped with extraction mechanisms, the extraction mechanisms need to be opened for a long time and cannot perform corresponding actions with the start and close of grinding, which results in power consumption when no extraction is performed.
[0004] In order to solve the above problems, a dust collection type grinder is proposed in the present application. Utility Model Content

[0009] An extraction mechanism for particle suction is fixedly connected to the end of the driving shaft of the driving motor, and the grinding disc is driven by the transmission mechanism to rotate in the opposite direction to the extraction mechanism.
[0010] Preferably, the extraction mechanism includes a circular box, a partition plate and an air collecting hopper, the circular box is fixedly connected to the driving shaft of the driving motor, the partition plate is fixedly installed inside the circular box to divide the circular box into multiple air intake channels, and the air intake channels form air intakes on the outer periphery of the circular box, the air collecting hopper is fixedly installed inside the circular box and communicated with the air intake channels, one of the partition plates located at the air intakes extends to the outside of the circular box.
[0011] Preferably, an exhaust hopper is fixedly mounted on the round box.
[0012] Preferably, fan blades are fixedly installed inside the exhaust scoop, and the exhaust end of the exhaust scoop is connected to a discharge pipe via a rotary joint.
[0013] Preferably, the transmission mechanism includes a mounting shell, a driving gear, a driven gear and a transmission gear, the mounting shell is fixedly mounted on the outer shell of the driving motor, the driving gear is fixedly sleeved on the driving shaft of the driving motor, the mounting shell is rotatably connected to the grinding disc through a slider, the driven gear is fixedly mounted on the side of the grinding disc away from the round box, and is rotatably sleeved on the driving shaft of the driving motor, and the transmission gear is rotatably connected to the mounting shell through a rotating shaft for transmission of the driving gear and the driven gear.
[0014] The above technical solution of the utility model has the following beneficial technical effects:
[0015] When the driving motor starts, it drives the round box to rotate. At this time, the active gear drives the grinding disc to rotate through the transmission gear and the driven gear, so as to drive the grinding disc to turn in the opposite direction of the round box. The waste chips generated by the grinding of the grinding disc are dug out by the rotating partition plate on the round box and guided into the round box.
