[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-Figure 4 As shown, a high-stability three-lobe Roots blower includes a base 1, a blower body 2 is provided on the base 1, and a motor 3 is mounted on the base 1. A transmission belt 4 is provided between the motor 3 and the blower body 2, and a filter 5 is connected to the blower body 2. An exhaust pipe 8 is connected to the blower body 2, a mounting structure 6 is connected to the base 1, and a support assembly 9 is provided on the exhaust pipe 8. Pulleys are provided on the blower body 2 and the motor 3, and the transmission belt 4 is sleeved on the pulleys. A protective cover 10 is provided on the blower body 2 and the motor 3. A connector 7 is provided on the blower body 2, and the end of the exhaust pipe 8 is fixedly mounted on the connector 7.

[0020] When using a three-leaf Roots blower, the entire blower is stably installed through the mounting structure 6 on the base 1, and the exhaust pipe 8 is installed and connected using the connector 7, and a support assembly 9 is set on the exhaust pipe 8 to complete the installation of the entire blower. During use, after starting the motor 3, the motor 3 rotates the three-leaf rotor inside the blower body 2 through the transmission belt 4 and the pulley. During this process, the outside air enters the blower body 2 after being filtered by the filter 5, and is discharged from the exhaust pipe 8 under the action of the three-leaf rotor, thereby achieving the purpose of blowing. During the operation of the entire three-leaf Roots blower, the mounting structure 6 plays a role in reducing the impact of vibration, and the support assembly 9 supports the exhaust pipe 8, making the entire blower highly stable.

[0021] Through the above implementation scheme, the mounting structure 6 includes a base plate 601, a waist-shaped hole 602, a connecting column 603, an installation column 604, a support spring 605, a threaded hole 606, a mounting cover 607, a pressure plate 608, a stud 609 and a shock-absorbing spring 610. The waist-shaped hole 602 is opened on the base plate 601, and the base plate 601 is fixedly connected to the connecting column 603. The connecting column 603 passes through the base 1, and the installation column 604 passes through the base 1 and is fixedly connected to the base plate 601. The support spring 605 is sleeved on the installation column 604, and the support spring 605 is located between the base 1 and the base plate 601. The threaded hole 606 is opened at the upper end of the installation column 604. The mounting cover 607 and the pressure plate 608 are fixedly connected, the stud 609 is installed on the mounting cover 607, and the stud 609 is threadedly connected to the threaded hole 606, the shock-absorbing spring 610 is sleeved on the upper end of the mounting column 604, and the shock-absorbing spring 610 is located between the base 1 and the pressure plate 608.

[0022] By setting up the mounting structure 6, after the three-leaf Roots blower is fixedly installed, the vibration generated during the operation of the three-leaf Roots blower can be reduced by the support spring 605 and the shock-absorbing spring 610, thereby ensuring the connection stability of the corresponding screws and preventing the screws from loosening. The relative position of the pressure plate 608 can be adjusted by using the mounting cover 607 and the stud 609, thereby changing the compression degree of the two springs and adjusting the shock-absorbing effect, and the adaptability is high.

[0023] When installing the mounting structure 6, a support spring 605 is installed on the mounting column 604. The connecting column 603 and the mounting column 604 are inserted into the bottom plate of the base 1. A shock-absorbing spring 610 is installed on the mounting column 604. Then, the stud 609 on the mounting cover 607 is screwed into the threaded hole 606. The shock-absorbing spring 610 is compressed using the pressure plate 608. The pressure plate 608 is adjusted so that the shock-absorbing spring 610 and the support spring 605 are in different degrees of compression. After the mounting structure 6 is set, the blower is installed. The blower is moved to a suitable location and placed. The screws are inserted through the waist-shaped holes 602 on the bottom plate 601 to secure it. After the blower is installed, it is used. During use, the shock-absorbing spring 610 and the support spring 605 have a shock-absorbing effect, increasing the stability of the blower.

[0024] Through the above implementation scheme, the support assembly 9 includes a first jacket 901, a second jacket 902, an anti-slip lining 903, a connecting bolt 904, a support rod 905, a support block 906 and an adjusting screw 907. The anti-slip lining 903 is arranged on the inner side of the first jacket 901 and the second jacket 902, and the first jacket 901 and the second jacket 902 are sleeved on the exhaust pipe 8. The connecting bolt 904 passes through the ends of the first jacket 901 and the second jacket 902, and a nut is provided at the end of the connecting bolt 904. The support rod 905 is fixed to the lower end of the first jacket 901, and the support block 906 is connected to the support rod 905 through the adjusting screw 907.

[0025] A support assembly 9 is provided on the exhaust duct 8, and the exhaust duct 8 is supported by the support assembly 9, thereby increasing the operational stability of the exhaust duct 8 and enhancing the operational stability of the entire three-leaf Roots blower. The support block 906 can be adjusted by adjusting the screw 907 to ensure the supporting effect of the support assembly 9. The support assembly 9 can also be quickly disassembled for easy replacement.

[0026] When installing support assembly 9, first jacket 901 and second jacket 902 are placed on exhaust duct 8, with anti-slip lining 903 contacting exhaust duct 8. Connecting bolts 904 and nuts are used to secure the two jackets. At this point, with the help of anti-slip lining 903, support assembly 9 is stably installed on exhaust duct 8. Adjustment screw 907 is then rotated, and adjustment screw 907 rotates on support rod 905, lowering support block 906 until support block 906 contacts the ground, thus completing the installation and adjustment of support assembly 9. During use, support assembly 9 provides support, ensuring good stability of exhaust duct 8 and further ensuring the stability of the entire blower.
