[0025] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0026] As Figures 1 to 7As shown in the figure, a new type of grain conveying device includes a frame 1, on which a driving roller 2 and a driven roller 3 are connected. A conveyor belt 4 is wound between the driving roller 2 and the driven roller 3. The conveyor belt 4 includes an upper horizontal section 41, an inclined section 42 and a lower horizontal section 43. The upper horizontal section 41 is higher than the lower horizontal section 43. The two ends of the inclined section 42 are respectively connected to the upper horizontal section 41 and the lower horizontal section 43. Above the lower horizontal section 43, there is a grain inlet hopper 5. At the left end of the upper horizontal section 41, there is a grain unloading hopper 6. Below the grain unloading hopper 6, there is a grain falling pipe 7. Specifically, the grain falling pipe 7 includes an inlet section pipe 71, an outlet section pipe 72 and a bent section pipe 73 communicating with the inlet section pipe 71 and the outlet section pipe 72. The inlet section pipe 71 is connected to the bottom of the grain unloading hopper 6. On the left side of one of the bends of the bent section pipe 73, there is a dust suction port 8, and the dust suction port 8 is connected to a dust suction assembly. On the right side of one of the bends of the bent section pipe 73, there is an air inlet 9. The air inlet 9 is horizontally oriented towards the dust suction port 8 and is arranged on the side wall of the grain falling pipe 7, and the air inlet 9 is connected to a blowing assembly.

[0027] Please refer to again Figure 2 and Figure 3 , the blowing assembly includes an air inlet pipe 10 and an air pump 11. One end of the air inlet pipe 10 is communicated with the air inlet 9, and the other end of the air inlet pipe 10 is provided with a pipe one 12 communicated with the air pump 11. The function of the pipe one 12 is to guide the gas to the air inlet 9.

[0028] Specifically, the dust suction assembly includes a dust suction pipe 13 and a dust suction fan 14. One end of the dust suction pipe 13 is communicated with the dust suction port 8, and the other end of the dust suction pipe 13 is connected to a pipe two 15. The pipe two 15 is communicated with the inlet of the dust suction fan 14. Both the air pump 11 and the dust suction fan 14 are installed on the frame 1.

[0029] Please refer to again Figure 4 , the cross-section of the grain falling pipe 7 is rectangular. The bent section pipe 73 is bent at least twice from top to bottom. Both the air inlet 9 and the dust suction port 8 are located at the lowermost bend. By setting the bent section pipe 73, the falling grain is buffered and decelerated. Then, the buffered and decelerated grain is blown by the air inlet 9. At the same time, under the action of the dust suction port 8, the dust mixed in the grain is adsorbed. After the air inlet 9 blows, the passing dust is blown towards the dust suction port 8 to ensure that the dust can enter the dust suction port 8, and the dust removal effect is good.

[0030] In this embodiment, the driving roller 2 is located at the right end of the lower horizontal section 43, and the driven roller 3 is located at the left end of the upper horizontal section 41. The driving roller 2 is connected to a driving assembly, and the driving assembly includes a motor 16 and a driven wheel 17 arranged on one side of the driving roller 2. The motor 16 is installed on the frame 1, and a driving wheel 18 is arranged on the output shaft of the motor 16. The driving wheel 18 and the driven wheel 17 are connected by a transmission belt 19. After the motor 16 is started, it drives the driving wheel 18. The driving wheel 18 transmits power to the driven wheel 17 through the conveyor belt, and the driven wheel 17 drives the driving roller 2 to rotate, thereby driving the conveyor belt 4 to run.

[0031] Please refer to again Figure 5 and Figure 6 , a first limiting component is arranged at the connection between the upper horizontal section 41 and the inclined section 42, and a second limiting component is arranged at the connection between the lower horizontal section 43 and the inclined section 42.

[0032] Specifically, the first limiting component includes a first supporting roller 20, a first belt pressing wheel 21 and a second belt pressing wheel 22. The two ends of the first supporting roller 20 are respectively rotatably arranged on the frame 1. The first belt pressing wheel 21 and the second belt pressing wheel 22 are respectively installed on both sides of the frame 1. The first belt pressing wheel 21 and the second belt pressing wheel 22 are located obliquely below the first supporting roller 20. The bottom of the conveyor belt 4 located above is slidably connected to the upper part of the first supporting roller 20. The two side edges of the conveyor belt 4 located below are respectively clamped between the first supporting roller 20 and the first belt pressing wheel 21 and between the first supporting roller 20 and the second belt pressing wheel 22.

[0033] The second limiting component includes a second supporting roller 23, a third belt pressing wheel 24 and a fourth belt pressing wheel 25. The two ends of the second supporting roller 23 are respectively rotatably arranged on the frame 1. The third belt pressing wheel 24 and the fourth belt pressing wheel 25 are respectively installed on both sides of the frame 1. The third belt pressing wheel 24 and the fourth belt pressing wheel 25 are located obliquely above the second supporting roller 23. The top of the conveyor belt 4 located below is slidably connected to the lower part of the second supporting roller 23. The two side edges of the conveyor belt 4 located above are respectively clamped between the second supporting roller 23 and the third belt pressing wheel 24 and between the second supporting roller 23 and the fourth belt pressing wheel 25.

[0034] Among them, the first belt pressing wheel 21 and the second belt pressing wheel 22, the third belt pressing wheel 24 and the fourth belt pressing wheel 25 are all in contact with the outer surface of the conveyor belt 4 to change the transmission direction of the conveyor belt 4. At the same time, the first supporting roller 20 and the second supporting roller 23 are both in contact with the inner surface of the conveyor belt 4 to support the conveyor belt 4. Through the above set structure, the utility model realizes the combination of three conveying forms: horizontal conveying, inclined conveying and horizontal conveying. Functionally, it integrates a horizontal conveyor and an inclined conveyor into one, and can replace two traditional horizontal conveyors and one inclined conveyor to continuously convey grain to a designated position.

[0035] In addition, the applicant wishes to state that there is a technical problem of grain leakage in the existing grain conveyors during the transmission process. Especially during the transmission on a large slope, it is sometimes necessary to add a protective cover to avoid waste of grain, which increases the production cost of the equipment. Therefore, in the present utility model, baffles 26 are provided on both sides of the surface of the conveyor belt 4, and a plurality of partitions 27 perpendicular to the conveyor belt 4 and evenly spaced are provided on the inner sides of the two baffles 26. By providing the partitions 27 and the baffles 26, the conveyor belt 4 is divided into multiple square frames, which can effectively prevent the grain from falling under the condition of a large inclination angle and improve the conveying efficiency.

[0036] It is worth mentioning that, referring again to Figure 7 , the baffle 26 is located inside the third pressure roller 24 and the fourth pressure roller 25. Correspondingly, the baffle 26 is also located between the first pressure roller 21 and the second pressure roller 22. In this way, during the operation of the conveyor belt 4, interference between the baffle 26 and each pressure roller can be prevented. And, the baffle 26 is made of rubber, and the baffle 26 adopts a zigzag and circuitous wavy bending structure. In this way, the conveyor belt 4 can utilize the wavy structure to adapt to elastic deformation at the turning point, which is beneficial to extending the service life of the conveyor belt 4.

[0037] The usage method of this product is as follows:

[0038] During use, the motor 16 is started. After the motor 16 is started, it drives the driving wheel 18. The driving wheel 18 transmits power to the driven wheel 17 through the conveyor belt. The driven wheel 17 drives the driving roller 2 to rotate, thereby driving the conveyor belt 4 to operate; during the operation of the conveyor belt 4, the grain is poured into the feeding hopper 5, and the grain conveyed by the lower horizontal section 43 is smoothly sent to the upper horizontal section 41 through the inclined section 42 and sent out. Then the grain enters the unloading hopper 6, and the grain passing through the unloading hopper 6 enters the grain dropping pipe 7. Subsequently, during the falling process of the grain in the grain dropping pipe 7, the suction fan 14 is started, and the negative pressure is generated in the dust suction pipe 13 by using the suction fan 14. At this time, under the action of the dust suction port 8, the dust mixed with the grain is adsorbed, and by starting the air pump 11, the air inlet and outlet pipe 10 is blown by using the air pump 11, and the dust passing through after the air inlet 9 is blown towards the dust suction port 8 to ensure that the dust can enter the dust suction port 8, so as to separate the dust from the grain and improve the quality of the grain; the dust-removed grain is discharged through the outlet pipe.

[0039] To sum up, the present utility model blows air on the falling grain through the air pump 11, and cooperates with the negative pressure generated by the suction fan 14, which can significantly enhance the dust removal effect during the falling process of the grain, with a convenient operation process and a good dust removal effect.

[0040] The above-described embodiments are only the preferred embodiments of the present utility model and do not limit the scope of implementation of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present utility model patent shall be included within the scope of the patent application of the present utility model.
