The first fixed frame 12 is movably connected to a collecting box 13 inside, and the collecting box 13 is also movably connected to the protective cover 6. The protective cover 6 passes through the shaft on the machine base 2 through the groove 8, so that the protective cover 6 covers the top of the machine base 2. A protective net 9 is also fixed on the protective cover 6 to protect the operator from injuries caused by broken grinding wheels or splashing cuttings. The first fixed frame 12 is fixed on the protective cover 6, and the collecting box 13 is slid in the first fixed frame 12, which can push the collecting box 13 to move into the protective cover 6, so that the collecting box 13 is located below the grinding wheel 3, which is convenient for collecting debris generated during grinding of the workpiece.

[0019] refer to Figure 1The positioning assembly 4 includes a fixed seat 41, which is fixedly connected to the substrate 1 and located on one side of the machine base 2. A motor 43 is fixedly connected to the upper end of the fixed seat 41. A slide groove 44 is provided on the side of the fixed seat 41 close to the machine base 2. A screw rod 42 is rotatably connected to the inside of the slide groove 44. One side of the lifting plate 5 is slidably connected to the slide groove 44, and one side of the lifting plate 5 is threadedly connected to the screw rod 42. By setting the positioning assembly 4, the fixed seat 41 is fixed to the machine base 2, and the fixed seat 41 is equipped with a motor 43. The motor 43 can rotate the screw rod 42 in the slide groove 44 of the fixed seat 41, so that the lifting plate 5 can slide on the fixed seat 41, thereby adjusting the height of the protective cover 6. The protective cover 6 moves downward to contact the substrate 1, is not prone to shaking, and can prevent debris from splashing during grinding for protection. The protective cover 6 moves upward for easy inspection and maintenance of the grinding machine.

[0020] refer to Figure 2 The hole blocking assembly 11 includes a hole blocking plate 111, which is slidably connected to one side of the through hole 10, and a handle 112 is fixedly connected to one side of the hole blocking plate 111. A slide rail 113 is fixedly connected to one side of the protective net 9 close to the through hole 10, and a limiting groove 114 is provided on one side of the slide rail 113, and one side of the hole blocking plate 111 is slidably connected to the inside of the limiting groove 114; by setting the hole blocking assembly 11, one side of the hole blocking plate 111 extends into the limiting groove 114 of the slide rail 113, and the handle 112 drives the hole blocking plate 111 to slide on the slide rail 113, so that the through hole 10 can be blocked, and foreign objects can be prevented from entering from the through hole 10 when not in use.

[0021] refer to Figure 2-3 One end of the collecting box 13 is fixedly connected to a round block 14, and a screw 15 is rotatably connected to the round block 14. One side of the screw 15 is threadedly connected to one side of the first fixed frame 12, and the end of the screw 15 away from the collecting box 13 is fixedly connected to a torsion block 16; by rotating the round block 14, the round block 14 causes the screw 15 to be threaded into the first fixed frame 12. Since the screw 15 rotates with the collecting box 13 through the round block 14, the collecting box 13 will not rotate, and the collecting box 13 can be pushed to move so that it extends into the protective cover 6 to collect debris. After the debris is collected, it is also convenient to retract it into the first fixed frame 12, and the debris in the collecting box 13 can be taken out with the help of a shovel or the like.

[0022] refer to Figure 4The positioning assembly 17 includes a second fixed frame 171, which is fixedly connected to one end of the lifting plate 5. A slide plate 172 is slidably connected inside the second fixed frame 171. A positioning rod 173 is fixedly connected to one end of the slide plate 172, and one side of the positioning rod 173 is movably connected to one side of the suspension rod 7. A spring 174 is fixedly connected between the slide plate 172 and the second fixed frame 171. A moving rod 175 is fixedly connected to one end of the slide plate 172 close to the spring 174. The moving rod 175 is away from the spring 174. One end of the slide plate 172 is fixedly connected with a lifting block 176; by setting the positioning component 17, the positioning rod 173 enters the lifting plate 5 and is inserted into the suspension rod 7, so that the protective cover 6 is fixed to the lifting plate 5, and the spring 174 can make the positioning rod 173 tightly inserted into the suspension rod 7 and fixed. When the protective cover 6 needs to be maintained or replaced, the lifting block 176 is pulled, and the lifting block 176 moves the moving rod 175. The moving rod 175 drives the slide plate 172 to move the positioning rod 173 away from the suspension rod 7, so that the protective cover 6 can be quickly removed.

[0023] Principle and advantages of use: The motor 43 drives the screw rod 42 to rotate, so that the screw rod 42 drives the lifting plate 5 to slide downward on the fixed seat 41, so that the protective cover 6 covers the grinding area of ​​the grinder, which can prevent most of the debris from splashing out and causing harm to the staff, reducing safety hazards, and then the torsion block 16 is rotated to rotate the screw rod 15, so that the screw rod 15 pushes the collection box 13 to slide in the first fixed frame 12 to the protective cover 6 below the grinding wheel 3, so as to collect the debris generated when the workpiece is ground, and then the baffle plate 111 on the protective net 9 is pushed open, and the baffle plate 111 slides on the protective net 9. The cylindrical workpiece is inserted through the through hole 10 to contact the grinding wheel 3 of the grinding machine for grinding, which greatly improves the safety of the workpiece during grinding. When the grinding machine needs to be repaired and maintained, the motor 43 is started again to drive the screw rod 42 to rotate, so that the protective cover 6 leaves the grinding machine and no longer blocks the grinding machine, which is convenient for repair and maintenance. When the protective cover 6 needs to be replaced, the lifting block 176 is pulled, and the lifting block 176 moves the moving rod 175. The moving rod 175 drives the slide plate 172 to move the positioning rod 173 away from the suspension rod 7, and the protective cover 6 can be removed.
