The utility model discloses a
grinding unit assembling and disassembling
assembly convenient to overhaul, which comprises a
grinding unit, a
grinding unit support and an anti-falling
assembly, a back plate is arranged on the upper side of the grinding unit, and a mounting groove with openings at the front end and the rear end is arranged on the back plate. An end plate located in the middle of a front end opening or the middle of a rear end opening of the mounting groove divides the front end opening or the rear end opening of the mounting groove into two
first insertion holes located in the left side and the right side, the grinding sub-support comprises a base plate, and the left side and the right side of the front end or the rear end of the base plate are each provided with an arm plate extending outwards. The back plate is located in the mounting groove in a penetrating connection mode, the arm plates located on the left side and the right side of the base plate correspondingly penetrate out of the two
first insertion holes located in the left side and the right side of the end plate and extend out of the mounting groove, the arm plates are provided with second
insertion holes and third
insertion holes in the front-back direction, the anti-disengaging
assembly comprises a check block and two n-shaped
insertion rods, and the check block is located on the outer side face of the end plate in an attached mode; through holes are formed in the two ends of the check block respectively, the n-shaped insertion rods are provided with
first insertion arm rods and second insertion arm rods, the first insertion arm rods are longer than the second insertion arm rods, one n-shaped insertion rod is inserted into the arm plate located on the left side of the base plate, and the other n-shaped insertion rod is inserted into the arm plate located on the right side of the base plate. The first insertion arm rods are connected into the corresponding second insertion holes in a limiting and penetrating mode through elastic limiting assemblies capable of stretching out and drawing back in the front-back direction, and the second insertion arm rods are connected into the corresponding through holes in the check blocks and the corresponding third insertion holes in a penetrating mode. According to the grinding unit assembling and disassembling assembly convenient to overhaul, the grinding unit is easy to overhaul and replace, and the overhaul efficiency of the grinding unit is greatly improved.
