Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Example 1:

[0038] like Figures 1 to 4 As shown, an air bag spring device for a vibrating screen comprises: a vibrating screen base 1, a storage bin is provided inside the vibrating screen base 1; a vibrating screen top seat 2, the vibrating screen top seat 2 is arranged above the vibrating screen base 1; an air source controller 3, the air source controller 3 is fixedly mounted on the top of the fixed bottom plate on the outside of the vibrating screen base 1, an air intake pipe 4 is fixedly connected to one side of the air source controller 3, a filter plate is fixedly mounted on the inner side of the pipe mouth of the air intake pipe 4, and an air supply pipe 5 is fixedly connected to the top of the air source controller 3; a distributor 6, the distributor 6 is arranged above the air source controller 3, the distributor 6 consists of a main pipe and three branches, and the distributor 6 main pipe is fixedly and sealedly connected to the air supply pipe 5; an air pressure monitoring component 7, the air pressure monitoring component 7 is arranged on one side of the distributor 6 main pipe; a one-way valve component 8, the one-way valve component 8 is arranged on the inner side of the distributor 6 main pipe; an air bag component 9, the air bag component 9 is arranged between the vibrating screen base 1 and the vibrating screen top seat 2.

[0039] The one-way valve assembly 8 includes: a vent plate 801, a second spring 804, a second connecting pipe 805 and a sealing plate 806. The vent plate 801 is fixedly connected to the inner side of the distributor 6 main pipe. The bottom end of the vent plate 801 is fixedly connected to the connecting pipe 1 802. The pipe mouth of the connecting pipe 1 802 is square. The inner side of the connecting pipe 1 802 is fixedly connected to the limiting shaft 803. The second spring 804 is sleeved on the outer side of the limiting shaft 803 and one end of the second spring 804 is fixedly connected to the top inner side of the connecting pipe 1 802. The connecting pipe 2 805 is square and slidably connected to the inner side of the connecting pipe 1 802. The connecting pipe 2 805 is slidably connected to the limiting shaft 803. The top of the connecting pipe 2 805 is fixedly connected to one end of the second spring 804. The sealing plate 806 is fixedly connected to the top of the connecting pipe 2 805. The bottom end of the sealing plate 806 is provided with a rubber pad and can maintain a seal with the pipe mouth of the distributor 6 main pipe when squeezed by the second spring 804.

[0040] Start the gas source controller 3 to absorb the external air supply through the suction pipe 4 and input it into the main pipe of the distributor 6 through the gas supply pipe 5. The air squeezes the sealing plate 806 to cause the spring 2 804 to contract, and the bottom pipe opening of the main pipe of the distributor 6 is opened. The gas flows into the branch pipe of the distributor 6 through the ventilation plate 801. When the gas supply is completed, the spring 2 804 rebounds and presses down the connecting pipe 2 805, so that the sealing plate 806 is close to the bottom pipe opening of the main pipe of the distributor 6 to prevent gas backflow.

[0041] The air pressure monitoring assembly 7 includes: a fixed tube 701, an extrusion plate 703, a pressure sensor 704, a connecting ring 706 and a spring 708. The fixed tube 701 is fixedly connected to one side of the distributor 6 main tube and communicates with the distributor 6 main tube. The top and bottom ends of the inner side of the fixed tube 701 are fixedly connected to the limit plate 702. The extrusion plate 703 is slidably connected to the inner side of the fixed tube 701. The edge of the extrusion plate 703 is provided with a rubber ring and can maintain a seal with the fixed tube 701 when sliding. The pressure sensor 704 is fixedly installed at the top and bottom ends of the inner side of the fixed tube 701. A fixed shaft 705 is fixedly connected between the pressure sensors 704. The connecting ring 706 is slidably connected to the outside of the fixed shaft 705. Support rods 707 are rotatably connected on both sides of the connecting ring 706. One end of the support rod 707 is rotatably connected to the extrusion plate 703. Spring 708 is sleeved on the outside of the fixed shaft 705 and fixedly connected between the connecting ring 706 and the pressure sensor 704. Spring 708 has its own damper.

[0042] After installing the airbag assembly 9, the buffer strength needs to be debugged. At this time, the air source controller 3 is started to supply air to the airbag spring 901. As the air supply continues, the air pressure inside the airbag spring 901 increases, pushing the extrusion plate 703 to slide. The extrusion plate 703 causes the driving support rod 707 to rotate, so that the connecting ring 706 slides on the outside of the fixed shaft 705 to squeeze the spring 708. The pressure sensor 704 can monitor the pressure and display it through an externally connected display device to assist in debugging the buffer strength. When exhaust is required, the inflation tube 904 and the branch pipe of the distributor 6 can be disassembled and separated. The debugging is quick and convenient. In addition to the debugging stage, the air pressure monitoring assembly 7 can also monitor the pressure inside the airbag spring 901 during buffering in real time, so that when the airbag spring 901 is damaged or the pipeline leaks, the vibrating screen can be stopped in time to prevent damage to the vibrating screen.

[0043] During operation, the airbag spring 901 compresses the air and utilizes the principles of aerodynamics and its compressibility. As the vibration load changes, the height and inner cavity volume of the airbag spring change accordingly, achieving a nonlinear elastic effect, realizing a smooth and flexible transmission of the vibration load (energy), and completing efficient control of the vibration amplitude and vibration load of the vibrating screen.

[0044] The airbag assembly 9 includes: an airbag spring 901 and an inflation tube 904. The airbag spring 901 is located between the vibrating screen body base 1 and the vibrating screen body top seat 2. The top and bottom ends of the airbag spring 901 are fixedly connected to the mounting plate 902. The mounting plate 902 is fixedly connected to the top of the vibrating screen body base 1 and the bottom end of the vibrating screen body top seat 2 by fixing bolts 903; the inflation tube 904 is fixedly connected to the bottom end of the mounting plate 902 at the bottom end of the airbag spring 901 and is connected to the inside of the airbag spring 901. The inflation tube 904 is fixedly and sealedly connected to the branch pipe of the distributor 6.

[0045] The utility model discloses an air bag spring device applied to a vibrating screen, which comprises multiple groups of air bag spring devices used together.

[0046] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components.
