DETAILED DESCRIPTION

[0019] 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.

[0020] Example 1: Reference Figure 1-4 The grinding drive mechanism of a single-sided grinder shown in the figure includes a driven wheel 2 provided at the bottom of a grinding disc 1, and a driving motor 3 is provided on one side of the grinding disc 1, a driving wheel 4 is provided on the driving shaft of the driving motor 3, and the driving wheel 4 is connected to the driven wheel 2 by a chain 5. In order to extend the service life of the chain 5 and thus extend the service life of the entire driving mechanism, a cleaning mechanism 6 and a lubrication mechanism are provided at the position of the chain 5 to regularly clean and lubricate the chain 5.

[0021] Cleaning mechanism: The cleaning box 61 is provided with supporting parts such as pillars at the bottom to prevent the entire weight of the cleaning box 61 from falling on the chain 5. The front and rear ends of the cleaning box 61 are provided with through holes 62 for the chain 5 to pass through. The two groups of cleaning brushes 7 arranged inside the cleaning box 61 are two groups, which are symmetrically arranged on the left and right. The internal top surface of the cleaning box 61 is provided with a sliding hole 63 connected to the outside. In order to enable the two groups of cleaning brushes 7 to clamp the chain 5 when in use, an adjustment mechanism is provided on the top surface of the cleaning box 61. The adjustment mechanism cooperates with the cleaning brush 7 through the connecting mechanism installed in the sliding hole 63 to control the relative movement of the cleaning brush 7, thereby clamping the chain 5. Therefore, after the chain 5 is clamped, the hard bristles of the cleaning brush 7 are used to remove the attached objects during the movement.

[0022] When the locking nut 75 is unlocked, the locking nut 77 is unlocked and the locking nut 78 is unlocked, so that the locking nut 77 is unlocked and the master lock 73 is unlocked.

[0023] Adjustment mechanism: A mounting frame 8 is provided on the top surface of the cleaning box 61, and an adjustment motor 9 is installed on the top surface of the mounting frame 8. Its driving shaft passes through the mounting frame 8 and is installed with an elliptical adjustment wheel 91. The adjustment wheel 91 is slidably connected to a semi-circular disk 78 installed at the end of the connecting member 74. When the adjusting wheel 91 rotates, the spring 77 drives the connecting member 74 to slide on the mounting bolt 76, thereby realizing the movement of the cleaning brush 7.

[0024] The bottom of the cleaning box 61 is provided with a hole connected to the outside world. When the attachments on the cleaning brush 7 fall off, they fall into the receiving hopper. The limiting strip 64 provided at the bottom of the cleaning box 61 is adapted to the wedge-shaped groove on the receiving hopper, thereby achieving the purpose of quick disassembly and quick installation.

[0025] Lubrication mechanism: The lubrication box 10 is arranged on the other section of the chain 5, and adopts the same support method as the cleaning box 61. The oil bottle 13 installed on the top surface of the cleaning box 61 has its oil nozzle inserted into the lubrication box 10 and is located above the chain 5. The bottle body of the oil bottle 13 is made of plastic material. The bracket 11 on the top of the lubrication box 10 has a telescopic cylinder 12 on the bracket 11. When the telescopic end is started, the bottle body is squeezed to complete the oil spraying, thereby achieving the purpose of lubricating the chain 5.

[0026] The practical working principle of the present invention is as follows: after the equipment has been used for a period of time, the adjusting motor 9 on the mounting bracket 8 is started, and the adjusting motor 9 drives the adjusting wheel 91 provided on the driving shaft, so that the adjusting wheel 91 rotates, so that the semi-circular disk 78 in contact with it also moves synchronously, and the semi-circular disk 78 drives the connecting member 74 to move in the sliding hole 63 during the movement, and the connecting member 74 slides on the mounting bolt 76 through the No. 2 hole 75 provided thereon, and the power source of its sliding is the spring 77 in the present working principle that is a tension spring, so the tension spring works to pull the connecting member 74 toward the middle, and then the connecting member 74 drives the cleaning brush 7 installed at the bottom to converge toward the middle, so that the brush part thereof contacts the chain 5, and the cleaning brush 7 is pulled toward the middle by the cleaning brush 7 installed at the bottom. During the movement of the chain 5, it is cleaned. When the cleaning is completed, some of the attachments on the cleaning brush 7 fall off under the action of gravity, pass through the hole at the bottom of the cleaning box 61 and fall into the receiving hopper (the wedge-shaped groove on the top of the receiving hopper cooperates with the wedge-shaped limit bar 64 to achieve rapid disassembly and assembly of the receiving hopper), complete the collection, and then the chain 5 continues to move for a few turns, and then the motor 9 is adjusted to rotate in the opposite direction to reset the above structure and release the cleaning of the chain 5; after the cleaning is completed, the bracket 11 on the top of the lubrication box 10 and the telescopic end of the telescopic cylinder 12 thereon work, squeeze downward, push the bottle body of the oil bottle 13, so that the lubricating oil is squeezed out of the bottle and falls on the chain 5, thereby achieving lubrication of the chain 5.

[0027] The end covers at the ends of the cleaning box 61 and the lubrication box 10 are both split-type designs and can be removed from the box body. If the cleaning brush 7 needs to be replaced, the end cover is removed, the fixing bolt 73 is rotated, the limit of the fixing bolt 73 on the connecting piece 74 is released, and then the cleaning brush 7 is pulled to separate the limiting groove 71 and the connecting piece 74, and the fixing bolt 73 is also taken out from the No. 1 hole 72. After cleaning the cleaning brush 7, the reverse operation is performed to install it back into the casing.
