[0018] As Figures 1-3 Shown, a dust fall conveying belt for concrete production, including conveying belt body 1, is equipped with dust cover 3 on conveying belt body 1, and dust cover 3 surrounds the left and right and top surface of conveying belt, and the both ends of dust cover 3 are open, and dust cover 3 is equipped with baffle 4, and dust removal cavity is formed between baffle 4 and the top plate of dust cover 3, and a plurality of exhaust fans 5 are arranged in dust removal cavity, and a plurality of dust removal holes 6 are arranged on baffle 4, and the air inlet end of dust removal cavity is open, and the air outlet end is connected with dust removal pipe 7.

[0019] Preferably, the dust removal pipe 7 is provided with a pipeline fan 8, and the air outlet end of the dust removal cavity is connected with the pipeline fan 8 through a wind collecting box 9. The pipeline fan is arranged on the dust removal pipe and connected through the wind collecting box. The pipeline fan can enhance the air extraction capacity of the dust removal cavity, so that the dust-containing air can be discharged through the dust removal pipe more quickly. The wind collecting box can effectively collect the air from the air outlet end of the dust removal cavity and then deliver it to the pipeline fan, thereby improving the dust collection efficiency and achieving better dust fall effect.

[0020] Preferably, the dust removal pipe 7 is connected to a dust removal water tank. The dust removal pipe is connected to the dust removal water tank, and the dust collected from the conveying belt enters the dust removal water tank along with the airflow. The water in the water tank can dissolve, settle and treat the dust, so as to avoid the dust from being discharged into the air again to cause secondary pollution, realize harmless treatment of the dust, and meet the environmental protection requirements.

[0021] Preferably, the feeding end of the conveying belt body 1 is provided with a feeding barrel 2.

[0022] Preferably, as shown in Figure 4 、 5 , the conveying belt body 1 has a structure of low in the middle and high on both sides.

[0023] Preferably, the conveying belt body 1 is provided below with a horizontal bearing roller 10, and the horizontal bearing roller 10 is provided on both sides with upwardly inclined inclined bearing rollers 11. The conveying belt body is designed to have a structure of low in the middle and high on both sides, and such a shape can constrain the gravel on the conveying belt. During the conveying process, the material can be effectively prevented from falling off from both sides of the conveying belt, the material loss is reduced, and the continuity and stability of the conveying process are ensured.

[0024] Preferably, the feeding barrel 2 is connected to a storage tank.

[0025] When the conveying belt is running, the exhaust fan is started, and the air is rapidly convected in the dust removal cavity to form a negative pressure. The dust-containing air enters the dust removal cavity through the dust removal holes on the partition plate under the action of the negative pressure. With the continuous work of the exhaust fan, the dust-containing air is continuously sucked into the dust removal cavity from the air inlet end of the dust removal cavity and flows towards the air outlet end. The air outlet end of the dust removal cavity is connected to the dust removal pipe, and the dust-containing air rapidly passes through the dust removal pipe under the action of the pipeline fan. If the dust removal pipe is connected to the dust removal water tank, the dust can be contacted with water in the dust removal water tank, and the dust can be absorbed and settled by the water, so as to realize separation of the dust from the air, and the purified air can be discharged into the atmosphere to avoid pollution of the environment by the dust.
