DETAILED DESCRIPTION
[0020] 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.
[0021] See also Figure 1-6 , the utility model provides an embodiment: a coal mill base fixing device, including a base 1;
[0022] Four groups of first slide grooves 2 are provided in the base 1, and legs 3 are movably inserted in the four groups of first slide grooves 2. A base 4 is fixedly installed on the upper ends of the four groups of legs 3. Storage grooves 5 are symmetrically provided at the upper end of the base 1. Lifting components are provided in the two groups of storage grooves 5, and the lifting components are fixedly connected to the base 4. Limiting components are provided in the lower ends of the four groups of first slide grooves 2 and the four groups of legs 3. The device lowers the four groups of legs 3 and the base 4 through the lifting components, thereby connecting the four groups of legs 3 and the base 4 with the base 1, and then fixes the four groups of legs 3 and the base 1 together through the limiting components.
[0023] Further, the lifting assembly includes two sets of bidirectional screws 6, which are rotatably installed in two sets of storage grooves 5, and the two sets of bidirectional screws 6 are symmetrically sleeved with sliders 7, and the lower ends of the two sets of storage grooves 5 are provided with two sets of second slide grooves 8, and the lower ends of the four sets of sliders 7 are inserted into the four sets of second slide grooves 8, and the upper ends of the four sets of sliders 7 are hingedly installed with support rods 9, and the upper ends of the four sets of support rods 9 are hinged to the lower side of the machine base 4, and the right ends of the two sets of bidirectional screws 6 are fixedly installed with synchronous wheels 10 , a synchronous belt 11 is sleeved on the two sets of synchronous wheels 10, a motor 12 is fixedly installed on the right side of the base 1, and the output shaft of the motor 12 is connected to the synchronous wheel 10. The structure drives the two sets of bidirectional screws 6, the two sets of synchronous wheels 10 and the synchronous belt 11 to rotate through the rotation of the output shaft of the first protrusion 13, and the rotation of the two sets of synchronous wheels 10 will drive the four sets of sliders 7 to slide. The four sets of sliders 7 slide through the four sets of support rods 9 to lower the base 4 and fit it to the upper side of the base 1, so that the base 4 can be docked with the base 1.
[0024] Furthermore, the inner walls of the four groups of second slide grooves 8 and the lower ends of the four groups of sliders 7 are all T-shaped, and the lower ends of the four groups of sliders 7 slide in the four groups of second slide grooves 8. This structure allows the lower ends of the four groups of sliders 7 to slide and guide in the four groups of second slide grooves 8 according to the shapes of the inner walls of the four groups of second slide grooves 8 and the four groups of sliders 7, and prevents the four groups of sliders 7 from sliding out of the four groups of second slide grooves 8.
[0025] Furthermore, the heights of the upper and lower sides of the two groups of storage grooves 5 are higher than those of the upper and lower sides of the four groups of sliders 7. The four groups of sliders 7 are located at the left and right ends of the two groups of storage grooves 5. This structure facilitates the sliding of the four groups of sliders 7 to store the four groups of support rods 9 into the two groups of storage grooves 5 according to the size of the inner walls of the two groups of storage grooves 5, and the lower side of the machine base 4 can fit with the upper side of the base 1.

After the four groups of legs 3 are inserted into the four groups of first slide grooves 2, the four groups of first protrusions 13 are inserted into the four groups of first grooves 18, and the four groups of second protrusions 16 are squeezed and slid into the four groups of movable grooves 14 in the four groups of second grooves 19, and the four groups of limiting blocks 15 are squeezed and inserted into the four groups of limiting grooves 20 when the four groups of second protrusions 16 are squeezed, thereby limiting the digital legs 3 in the four groups of first slide grooves 2 to prevent the four groups of legs 3 and the base 4 from shaking on the base 1.
[0027] Furthermore, the upper left sides of the four groups of second protrusions 16 and the upper inner walls of the four groups of second grooves 19 are all inclined, the upper left sides of the four groups of second protrusions 16 and the upper inner walls of the four groups of second grooves 19 have the same inclination angles, the lower sides of the four groups of limiting grooves 20 are higher than the upper sides of the four groups of second grooves 19. According to the structure that the upper left sides of the four groups of second protrusions 16 and the upper inner walls of the four groups of second grooves 19 are all inclined, when the four groups of second protrusions 16 are inserted into the four groups of second grooves 19, they are squeezed and slide into the four groups of movable grooves 14 through the upper inner walls of the four groups of second grooves 19 and the four groups of second protrusions 16.

Figure 3 , Figure 5 and Figure 6 As shown, the four groups of first protrusions 13 in the four groups of first slide grooves 2 are inserted into the four groups of first grooves 18 at the lower ends of the four groups of supporting feet 3, and the four groups of second protrusions 16 slide into the four groups of second grooves 19, and the four groups of second protrusions 16 are squeezed by the upper inner walls of the four groups of second grooves 19 and slide into the four groups of movable grooves 14, and then the four groups of limiting blocks 15 are inserted into the four groups of limiting grooves 20 under the force of squeezing the four groups of second protrusions 16, so that the four groups of supporting feet 3 can be limited and fixed in the four groups of first slide grooves 2.
