[0017] As Figures 1-3 shown, a discharging dust cover of the present utility model includes a chute 1, a cover body 2, an annular pipe 3 and a branch pipe 4. The cover body 2 is a rectangular cover with an open bottom surface. The chute 1 is fixedly connected to the top wall of the cover body 2, and the chute 1 is communicated with the cover body 2. The annular pipe 3 is sleeved outside the chute 1, and the annular pipe 3 is arranged above the top wall of the cover body 2. The branch pipe 4 is fixedly connected between the annular pipe 3 and the top wall of the cover body 2, and the branch pipe 4 communicates the cover body 2 and the annular pipe 3. Both the cover body 2 and the annular pipe 3 are provided with holes for connecting the branch pipe 4; an exhaust pipe 5 is fixedly connected to the annular pipe 3, and the exhaust pipe 5 is communicated with the annular pipe 3. A hole for connecting the exhaust pipe 5 is provided on the side wall of the annular pipe 3; the annular pipe 3 is a rectangular annular pipe, and a plurality of branch pipes 4 are provided. The plurality of branch pipes 4 are arranged along the rectangle of the annular pipe 3; the annular pipe 3 includes a straight pipe I 301, an arc elbow 302 and a straight pipe II 303. There are two straight pipes I 301, and the two straight pipes I 301 are parallel. There are two straight pipes II 303, and the two straight pipes II 303 are parallel. There are four arc elbows 302, and the four arc elbows 302 are respectively connected between the two straight pipes I 301 and the two straight pipes II 303. The two straight pipes I 301, the two straight pipes II 303 and the four arc elbows 302 form a rounded rectangle.
[0018] At the bottom of each straight pipe I 301, a plurality of branch pipes 4 are connected, and the plurality of branch pipes 4 are linearly distributed uniformly along the length direction of the straight pipe I 301; at the bottom of each straight pipe II 303, a plurality of branch pipes 4 are connected, and the plurality of branch pipes 4 are linearly distributed uniformly along the length direction of the straight pipe II 303; at the bottom of each arc elbow 302, at least one branch pipe 4 is connected; the air extraction pipe 5 is fixedly connected to the outer wall of one straight pipe I 301.
[0019] A lining plate is connected to the inner wall of the chute 1.
[0020] The cover body 2 of the present utility model is covered on the truck cargo box. Generally, the cover body 2 is set to have the same length and width as the truck cargo box. However, when the length and width of the cover body 2 are smaller than those of the truck cargo box, in order to prevent dust from flying during unloading, a baffle cloth can be set at the gap between the cover body 2 and the truck cargo box for hiding; the upper part of the chute 01 is connected to equipment such as a double-shaft humidifying mixer. The material is transported into the truck cargo box through the chute 01 and the cover body 2. The air extraction pipe 5 is connected to the suction pipe of the bag filter through a pipeline. The annular pipe 3 sucks the dust generated during the unloading process inside the cover body 2 to the bag filter through the branch pipes 4 for purification treatment, so that the bag filter can be used when the material is unloaded and loaded onto the vehicle.
[0021] The branch pipes 4 not only realize the connection between the annular pipe 3 and the cover body 2 but also play a role in supporting the branch pipes 4. The setting of the plurality of branch pipes 4 improves the dust absorption range and absorption efficiency, and at the same time improves the stability of the annular pipe 3.
[0022] The two straight pipes I 301, the two straight pipes II 303 and the four arc elbows 302 form a rounded rectangle, making the air flow in the annular pipe 3 more smooth and avoiding dust accumulation at the bend.
[0023] The setting of the lining plate extends the service life of the chute 1. The material of the lining plate can be selected according to the characteristics of the material. Commonly used lining plate materials are generally high manganese steel Mn13-4, high molecular polyethylene, high manganese cast steel, high chromium composite alloy or composite ceramics, etc.
