When the equipment is in use, when the exhaust pipe discharges gas, the gas pushes the rubber plate to move, and the movement of the rubber plate drives the connecting rod to move. When the connecting rod moves, it drives the first spring to displace and deform to generate elastic force, and then the rubber plate detaches from the inside of the slot. When the connecting rod moves, it drives the push rod to move. When the push rod moves, it pushes the protective cover to rotate on the surface of the protective pipe, and then the gas is discharged. By setting up the protective device, the exhaust pipe is effectively protected, which plays a role in protecting the exhaust pipe, reduces the risk of foreign matter easily entering the exhaust pipe when the equipment is in use, causing the exhaust pipe to be blocked and difficult to exhaust, and causing the driver to be unable to operate, thereby improving the practicality of the equipment.

[0015] 2. In the utility model, by setting a connecting device, when the equipment is in use, the user pulls the clamping block, and the movement of the clamping block drives the second spring to be displaced and deformed to generate elastic force, and then the clamping block is separated from the surface of the retaining ring, and then the protective tube is freed from the restraint, and the protective tube is pulled away from one end of the exhaust pipe. By setting the connecting device, the protective tube is effectively connected, which plays a role in quickly and firmly connecting the protective tube, reducing the use of bolts to firmly connect the exhaust pipe to the protective tube when the equipment is in use, and the installation and removal of the thread need to be operated with tools. The use of tools is too cumbersome, resulting in low work efficiency of the operator, thereby improving the practicality of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific arrangement and function of the protective device 6 and the connecting device 7 will be described in detail below.

[0024] In this embodiment: the protection device 6 is arranged at one end of the exhaust pipe 5, and the protection device 6 includes a protection tube 61 and a protection cover 62. The protection tube 61 is arranged at one end of the exhaust pipe 5, and the protection cover 62 is rotatably connected to one end of the protection tube 61. The interior of the protection tube 61 is fixedly connected to a limiting frame 65, and a card slot 63 is opened inside the protection tube 61. The interior of the limiting frame 65 is slidably connected to a connecting rod 66.

[0025] Specifically, one end of the connecting rod 66 is fixedly connected to a rubber plate 64 , and the rubber plate 64 is engaged with the inner wall of the slot 63 .

[0026] In this embodiment, by providing a rubber plate 64 , the card slot 63 can be restricted, thereby reducing the difficulty in isolating the protection tube 61 from the exhaust pipe 5 when the equipment is in use, thereby reducing the situation where debris enters the exhaust pipe 5 through the protection tube 61 .

[0027] Specifically, a first spring 67 is sleeved and connected to the surface of the connecting rod 66 , and two ends of the first spring 67 are fixedly connected to the surface of the limit frame 65 and the surface of the rubber plate 64 respectively. The first spring 67 is provided to facilitate applying a restoring elastic force to the rubber plate 64 .

[0028] Specifically, one end of the connecting rod 66 away from the rubber plate 64 is fixedly connected with a push rod 68 , and the push rod 68 abuts against the lower surface of the protective cover 62 . The push rod 68 is provided to facilitate the abutment of the protective cover 62 .

[0029] In this embodiment: a connecting device 7 is provided on the side of the protective tube 61, and the connecting device 7 includes a connecting block 71 and a retaining ring 72. The connecting block 71 is fixedly connected to the side of the protective tube 61, and the retaining ring 72 is fixedly connected to the surface of the exhaust pipe 5. A connecting groove 74 is opened on the side of the connecting block 71, and a clamping block 73 is slidably connected inside the connecting groove 74.

[0030] In this embodiment, by providing the block 73 , the protection tube 61 can be restricted, thereby reducing the risk that the protection tube 61 will be easily separated from the exhaust pipe 5 when the device is in use, making it difficult for the protection tube 61 to protect the exhaust pipe 5 .

[0031] Specifically, the block 73 is engaged with the surface of the ring 72 , a groove 75 is provided at one end of the block 73 , and the ring 72 is provided to limit the block 73 .

[0032] Specifically, a second spring 76 is fixedly connected inside the groove 75 , and one end of the second spring 76 away from the groove 75 is fixedly connected to the inner wall of the connecting groove 74 . The second spring 76 is provided to facilitate applying elastic force to the block 73 .

[0033] Working principle: When the equipment is in use, the user starts the driver 2 to operate, driving the connecting pipe 4 to generate suction force on the inside of the tank body 1, and then the material enters through the feed pipe 3. When the equipment is in use, when the exhaust pipe 5 discharges gas, the gas pushes the rubber plate 64 to move, and the movement of the rubber plate 64 drives the connecting rod 66 to move. When the connecting rod 66 moves, it drives the first spring 67 to displace and deform to generate elastic force, and then the rubber plate 64 disengages from the inside of the slot 63. When the connecting rod 66 moves, it drives the push rod 68 to move. When the push rod 68 moves, it pushes the protective cover 62 to rotate on the surface of the protective pipe 61, and then the gas is discharged. By setting the protective device 6, the exhaust pipe 5 is effectively protected, which plays a role in protecting the exhaust pipe 5, reduces the risk of foreign matter easily entering the exhaust pipe 5 when the equipment is in use, causing the exhaust pipe 5 to be blocked and difficult to exhaust, and causing the driver 2 to be unable to operate, thereby improving the practicality of the equipment.

[0034] When the equipment is in use, the user pulls the block 73, and the movement of the block 73 drives the second spring 76 to displace and deform to generate elastic force, and the block 73 is separated from the surface of the ring 72, and the protective tube 61 is freed from the restraint, and the protective tube 61 is pulled away from one end of the exhaust pipe 5. By setting the connecting device 7, the protective tube 61 is effectively connected, which plays a role in quickly and firmly connecting the protective tube 61, reducing the use of bolts to firmly connect the exhaust pipe 5 when the equipment is in use. The installation and removal of the thread need to be operated with tools, and the use of tools is too cumbersome, resulting in low work efficiency of the operator, thereby improving the practicability of the equipment.
