The turbulence cone (2) coincides with the axis of the dust suction pipe (1) and is arranged with a gap from the sector-shaped plate (3). A dust suction member is arranged in the middle and lower part of the dust suction pipe (1). The dust suction member includes a dust suction groove (4), a Venturi tube (5), and a filter screen (6). A dust suction groove (4) protruding outward is arranged in the middle and lower part of the dust suction pipe (1). A Venturi tube (5) is arranged outside the dust suction pipe (1). The suction pipe of the Venturi tube (5) is connected to the dust suction groove (4). The inlet end of the Venturi tube (5) is connected to a compressor source through a compressed air pipe, and the outlet end is connected to a dust filtering device through a discharge pipe (7). The filter screen (6) is arranged at the opening of the dust suction groove (4).

[0014] The dust suction groove (4) is integrally in a ring structure, and its cross-section is in a C-shaped or U-shaped structure. The dust suction groove (4) is integrally formed with the dust suction pipe (1) or detachably connected. At least two suction ports are evenly arranged on the circumference of the dust suction groove (4), and each suction port is connected to the Venturi tube (5). The filter screen (6) is arranged in a ring structure matching the shape of the dust suction groove (4).

[0015] Further, as shown in FIGS. 4 to 5, in another embodiment, the dust suction groove (4) is integrally hemispherical or dome-shaped. At least two dust suction grooves (4) are circumferentially and evenly arranged on the dust suction pipe (1). The dust suction groove (4) is integrally formed with or detachably connected to the dust suction pipe (1). Each dust suction groove (4) is connected to a Venturi tube (5), and the filter screen (6) is arranged in a circular structure matching the shape of the dust suction groove (4).

[0016] Further, as shown in FIG. 3, in another embodiment, the fan-shaped material plate (3) is arranged in a fan-shaped structure. At least two fan-shaped material plates (3) are circumferentially and evenly arranged on the inner wall of the dust suction pipe (1). The free end of the fan-shaped material plate (3) obliquely points downward to the axis line of the dust suction pipe (1), and the flow disturbance cone (2) is arranged concentrically with the fan-shaped material plate (3).

[0017] The fan-shaped material plate (3) is arranged in a horn-shaped structure with the tip downward, and the flow disturbance cone (2) is arranged concentrically with the fan-shaped material plate (3).

[0018] At least one anti-blocking device (8) is provided inside the filter screen (6). The anti-blocking device (8) is a vibrator or a vibrating striker.

[0019] A blowing ring pipe (9) is arranged at the lower part inside the dust suction pipe (1). Blowing holes are evenly arranged on the blowing ring pipe (9) to disperse the dust, better separate it from the fertilizer particles, and improve the suction effect of the Venturi tube (5).

[0020] An exhaust pipe (10) is provided on the upper part inside the dust suction pipe (1) and on the dust suction pipe (1) above the fan-shaped material plate (3). The exhaust pipe (10) is connected to any one of the discharge pipes (7), and a one-way valve (12) is provided on the exhaust pipe (10) to prevent backflow.

[0021] The working method of the utility model is as follows: the upper end of the dust suction pipe (1) is fixedly connected to the lower end of the discharge valve pipe (11) at the bottom of the fertilizer bin, and when the fertilizer bin is unloading, the compressed air source is started to deliver compressed gas to each venturi tube (5); on the other hand, each venturi tube (5) can also be connected to the exhaust pipe (10) of the pressure relief valve of the fertilizer bin, and when the fertilizer bin is unloading, the pressurized gas discharged by the pressure relief valve directly enters each venturi tube (5). When the fertilizer enters the dust suction pipe (1) from the discharge valve pipe (11), it is dispersed by the fan plate (3) and then guided by the spoiler cone (2) to separate the fertilizer particles from the dust. The fertilizer particles and the dust then fall along the dust suction pipe (1) to the dust suction trough (4). Under the negative pressure adsorption of the venturi tube (5), the lighter dust passes through the filter screen (6) and enters the dust suction trough (4), and then enters the venturi tube (5). Finally, it is connected to the dust filtering device through the discharge pipe (7) for processing, while the fertilizer particles continue to fall to the receiving device below. In order to ensure the suction and separation effect of the dust, during the suction process, the anti-blocking device (8) is turned on to vibrate or beat the filter (6) so that the fertilizer attached to the filter (6) falls off and prevents the filter (6) from being blocked. Furthermore, in order to increase the dust emission in the dust suction pipe (1), a blowing ring pipe (9) is provided at the lower part of the dust suction pipe (1), and compressed gas is blown upward through the blowing ring pipe (9) to blow the dust toward the dust suction groove (4), so that the venturi tube (5) can more fully suck the dust. An exhaust pipe (10) is provided on the dust suction pipe (1) above the fan plate (3), and the air collected at the upper part of the dust suction pipe (1) is quickly discharged by the exhaust pipe (10) to avoid blockage.
