[0003] In the process of conveying raw materials, dust is often generated due to the collision between blocky raw materials, which is extremely harmful to the health of workers. The dust is mostly raw material debris, and the dust suppression device of the general conveying device can only suppress the dust but cannot recycle the dust. At the same time, when the raw materials fall on the conveyor belt, the mechanical structure of the conveyor belt may be damaged due to the impact force. Utility Model Content

DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] like Figure 1-5 As shown, a cement material conveying device comprises a shell 1, a feed port 2 is provided at the upper portion of the shell 1, a discharge port 3 is provided at the lower portion of one side of the shell 1, a conveyor belt 4 is arranged inside the discharge port 3, and a recovery structure 6 is provided at the upper position of one side of the shell 1;
[0027] The recycling structure 6 includes a shell 7, which is welded to the upper side of the outer shell 1. The shell 7 is fixedly connected to the motor 14 through a connecting rod 13. The front end output shaft of the motor 14 is fixedly connected to the outside with a fan blade 15. A return port 9 is provided at the lower part of the other side of the outer shell 1. An inclined plate 8 is provided on one side of the return port 9 and is integrally formed with the outer shell 1. The lower part of the return port 9 is detachably connected to a recycling bag 11 through a connecting flange 10.
[0028] When the block raw materials for preparing cement are poured into the housing 1 from the feed port 2 , the dust generated by the collision of the raw materials is blown backwards by the fan blades 15 of the motor 14 , enters the rear part of the housing 1 , and finally enters the recovery bag 11 through the return port 9 .
[0029] In this embodiment, a screen is provided at the connection between the outer shell 1 and the housing 7 , and the screen is located in front of the fan blades 15 .
[0030] A screen is arranged in front of the fan blades 15 to prevent dust from entering the motor 14 and causing damage to the motor 14 .
[0031] In this embodiment, a buffer structure 12 is provided inside the shell 1 at a position above the conveyor belt 4, and the buffer structure 12 includes a rotating plate 16. The front ends of the rotating plate 16 are rotatably connected to the inner wall of the shell 1, and four spring buffers 17 are fixedly connected to the upper part of the rotating plate 16. The upper ends of the four spring buffers 17 are fixedly connected to a spring plate 18, and the side of the spring plate 18 close to the discharge port 3 is lower than the other side.
[0032] In order to prevent the block raw materials from falling directly onto the conveyor belt 4 after being poured into the shell 1 and damaging the mechanical structure of the conveyor belt 4, a rotating plate 16 is arranged inside the shell 1 above the conveyor belt 4. The upper part of the rotating plate 16 is connected to the spring plate 18 through a spring buffer 17. When the raw materials fall on the spring plate 18, the falling speed is buffered and finally they fall onto the conveyor belt 4, thereby effectively reducing the impact force of the raw materials.
[0033] In this embodiment, a through groove is provided in the middle of the rotating plate 16, and a rotating shaft 22 is slidably connected in the through groove through two connecting plates 23. The two connecting plates 23 are rotatably connected to the rotating shaft 22. The external rotation of the rotating shaft 22 is connected to a screw rod 20. The screw rod 20 passes through the lower part of the outer shell 1. The external thread of the screw rod 20 is connected to a sleeve 19, and the lower end of the sleeve 19 is fixedly connected to the outer shell 1.
[0034] A rotating shaft 22 is slidably connected to the middle of the rotating plate 16, and the outside of the rotating shaft 22 is rotatably connected to the screw 20, and the outside of the screw 20 is threadedly connected to the sleeve 19. Therefore, when the screw 20 is rotated, the rotating shaft 22 can be driven to move up and down, thereby driving the rotating plate 16 to rotate, and then causing the spring plate 18 connected to the rotating plate 16 to rotate, changing the angle of the spring plate 18, so that the rate at which the raw material falling on the spring plate 18 slides off the spring plate 18 changes, thereby achieving the change in the rate at which the raw material is delivered from the discharge port 3.
[0035] In this embodiment, a rotating wheel 21 is fixedly connected to the lower end of the screw rod 20 , and a limiting plate 24 is fixedly connected to the outside of the screw rod 20 between the rotating shaft 22 and the sleeve 19 .
[0036] A rotating wheel 21 is fixedly connected to the lower end of the screw 20 to facilitate the rotation of the screw 20. A limiting plate 24 is fixedly connected to the outside of the screw 20 between the rotating shaft 22 and the sleeve 19. When the limiting plate 24 contacts the sleeve 19, the screw 20 cannot move downward, indicating that the rotating plate 16 is in a horizontal state.
[0037] In this embodiment, four upright poles 5 are fixedly connected to the lower part of the housing 1 .
[0038] Four vertical poles 5 are arranged at the lower part of the housing 1 for supporting the housing 1 .
[0039] In this embodiment, a rubber door curtain is provided on the upper portion of the inner wall of the discharge port 3 .
[0040] A rubber door curtain is arranged at the discharge port 3, which does not hinder the transportation of raw materials and can have a certain dust suppression effect.
[0041] It should be noted that the utility model is a cement material conveying device. When in use, the motor 14 is started, and the block principle of cement preparation is poured into the shell 1 from the feed port 2. The raw materials collide with each other to generate dust. After the dust rises, it is blown backward by the fan blades 15 of the motor 14 and enters the rear part of the shell 1. Finally, it enters the recovery bag 11 through the return port 9. When the recovery bag 11 is full, the recovery bag 11 is removed. The dust collected in the bag is mostly raw material debris, which can be reused. The dust is poured out and the recovery bag 11 is put back.
[0042] After entering the housing 1, the block material will first fall on the spring plate 18. Since the lower part of the spring plate 18 is connected to the rotating plate 16 via the spring buffer 17, the material falling on the spring plate 18 will reduce the falling speed under the buffering effect of the spring plate 18 and the spring buffer 17, thereby reducing the impact force of the material falling on the conveyor belt 4.
[0043] When it is necessary to adjust the rate at which the raw materials are delivered from the discharge port 3, rotating the screw 20 can drive the rotating shaft 22 to move up and down, thereby driving the rotating plate 16 to rotate, and then causing the spring plate 18 connected to the rotating plate 16 to rotate, changing the angle of the spring plate 18, so that the rate at which the raw materials falling on the spring plate 18 slide off the spring plate 18 changes, thereby achieving the change in the rate at which the raw materials are delivered from the discharge port 3.
[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
