Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.
[0023] Reference Figure 1-Figure 4 , a buffer base for a cast iron machine for mining, comprising a box body 1 set as a hollow structure, a bracket 9 is slidably connected to the box body 1, a fixed sleeve 6 is installed on the bracket 9, an air bag 7 is fixedly installed in the fixed sleeve 6, two rotating shafts 11 are rotatably installed inside the box body 1, one end of each rotating shaft 11 is fixedly connected to a rotating plate 17, and the bottom surface of the bracket 9 and the surface of the two rotating plates 17 are in contact; two concave plates 16 are slidably installed in the box body 1, and the lower surface of each concave plate 16 is fixedly connected to two sliding rods 18, each sliding rod 18 is connected to the lower inner wall of the box body 1 through a first spring 14, and multiple sliding rods 18 are connected through a ring 13, and the rotating plate 17 will never contact the ring 13, and multiple extrusion blocks 15 are fixedly connected to the ring 13, and multiple moving components are arranged on the box body 1, each moving component includes a support rod 3 slidably installed on the box body 1, and one end of the support rod 3 is fixedly connected to a support plate 2.
[0024] A torsion spring 19 is sleeved on each rotating shaft 11, one end of the torsion spring 19 is fixedly connected to the rotating shaft 11, and the other end of the torsion spring 19 is fixedly connected to the inner wall of the box body 1. When the bottom surface of the bracket 9 moves downward against the surfaces of the two rotating plates 17 at the same time, the rotating plates 17 will rotate, and the rotating shaft 11 will rotate relative to the box body 1 at the same time, and the torsion spring 19 will be deformed.
[0025] Each extrusion block 15 is provided with an opening 12 with a right-angled trapezoidal cross-section, one end of each support rod 3 is fitted with the inclined surface of the corresponding opening 12, and each support rod 3 is sleeved with a second spring 10, one end of the second spring 10 is fixedly connected to the support rod 3, and the other end of the second spring 10 is fixedly connected to the surface of the box body 1. When the ring 13 moves upward together with the sliding rod 18, the inclined surfaces of each opening 12 will respectively move against one end of the corresponding support rod 3, thereby causing the support rod 3 and the box body 1 to slide relative to each other, and multiple second springs 10 will be deformed.
[0026] Two rotating rods 4 are hinged on the upper surface of each support plate 2, and a slider 5 is hinged at one end of each rotating rod 4. Two limit grooves are provided on the outer surface of the box body 1, and each slider 5 is slidably connected to the corresponding limit groove. Each slider 5 can only move up and down along the corresponding limit groove and cannot be separated from the limit groove. During the relative sliding of each support rod 3 and the box body 1, each support plate 2 will be driven to move away from the box body 1 at the same time, the inclination angle of the rotating rod 4 changes, and the slider 5 slides in the corresponding limit groove at the same time, thereby increasing the supporting area of the box body 1, so as to improve the stability of the base.
[0027] A plurality of rubber pads 8 are fixedly connected to the bracket 9, and the surface of each rubber pad 8 is in contact with the outer surface of the fixing sleeve 6.

This can improve the tightness of the connection between the fixing sleeve 6 and the bracket 9. When the airbag 7 is damaged, it is convenient to disassemble and replace the fixing sleeve 6.
[0028] In the utility model, when the iron block falls onto the surface of the airbag 7, the airbag 7 performs the initial buffering and reduction of the impact force of the iron block. Under the transmission action of the fixed sleeve 6, the bracket 9 will slide relative to the box body 1, and the bottom surface of the bracket 9 will simultaneously press against the surfaces of the two rotating plates 17 and move downward, so that the rotating plates 17 rotate, and the rotating shaft 11 simultaneously rotates relative to the box body 1, and the torsion spring 19 deforms. During the process of the upward rotation of one end of each rotating plate 17, it will respectively press against the lower surface of the corresponding concave plate 16 and move, thereby causing the concave plate 16 to move upward, and each slide bar 18 will simultaneously move upward in the box body 1. Since one end of each first spring 14 is fixedly connected to the corresponding slide bar 18, and the other end is fixedly connected to the box body 1, 1 is fixedly connected to the lower inner wall of the support rod 3, the first spring 14 is deformed, and the multiple first springs 14 and the torsion spring 19 can perform secondary buffering and reduction of the impact force. Since the ring 13 is fixedly connected to the multiple slide bars 18, when the ring 13 moves upward together with the slide bars 18, the inclined surfaces of each opening 12 will respectively move against one end of the corresponding support rod 3, thereby causing the support rod 3 and the box body 1 to slide relative to each other, and the multiple second springs 10 are deformed. Under the elastic force of the multiple second springs 10, the impact force can be further buffered and reduced. The buffering effect of the base is better, which can avoid damage to the base during the process of unloading the iron block, which is beneficial to prolonging the service life of the base and is convenient for the use of the base.
