[0018] Embodiment 1

[0019] As Figures 1-5As shown in the figure, a side discharging device for a belt conveyor, which is used for granular materials, includes a gantry 1 installed on the belt conveyor body. The gantry 1 is fixed to the frame 17 of the belt conveyor. The gantry 1 is a cuboid-shaped frame built by angle steel or profiles, with high structural stability, and is convenient for manufacturing and safe. A plow plate cooperating with the conveyor belt 14 is installed on the gantry 1. The plow plate is connected with a lifting drive device. Specifically, the lifting drive device includes a lifting frame 2 installed inside the gantry 1. An ear seat 15 is installed on the side of the lifting frame 2 and is then connected to the lifting drive device. A drive motor 5 for driving the lifting frame 2 to lift is installed on the gantry 1. The drive motor 5 is connected with a speed reducer. In this embodiment, the speed reducer is a double-output shaft speed reducer, and the two output shafts of the speed reducer have the same rotational speed, so as to be able to drive the lifting frame 2 to lift from multiple positions and ensure driving stability. A transmission seat 7 is also installed on the gantry 1. A lifting shaft 8 cooperating with the lifting frame 2 is installed on the transmission seat 7. The output shaft of the speed reducer is in transmission connection with the lifting shaft 8. A rack is installed on the lifting shaft 8, and a gear cooperating with the rack is installed on the transmission seat 7. The main shaft of the gear is connected to the speed reducer through a first transmission shaft 6. To ensure driving stability, there are four transmission seats 7 evenly distributed on both sides of the belt conveyor body. The speed reducer is in transmission connection with the two transmission seats 7 on the first side through the first transmission shaft 6. The transmission seats 7 on the second side are connected to the transmission seats 7 on the first side through a second transmission shaft 20, so as to drive the four lifting shafts 8 to lift synchronously and ensure the stable lifting of the lifting seat. A telescopic sleeve 9 is also sleeved on the lower end of the lifting shaft 8 to protect the lifting shaft 8 and prevent dust from adhering to the lower end of the lifting shaft 8. The ear seat 15 is connected to the lifting shaft 8 through a connecting arm 10. The connecting arm 10 is hinged to both the lifting shaft 8 and the ear seat 15, so as to automatically reduce the resistance caused by deformation.

[0020] The plow plate includes a discharging baffle 4 and a cleaning scraper 3 installed in sequence. The height value of the lower end of the discharging baffle 4 is greater than the height value of the lower end of the cleaning scraper 3, specifically 20 - 30 mm, so as to realize two-stage material blocking and discharging and disperse stress. The distance between the discharging baffle 4 and the cleaning scraper 3 is 200 - 300 mm, so as to form a stable discharging gap between the discharging baffle 4 and the cleaning scraper 3. The cross-sections of both the discharging baffle 4 and the cleaning scraper 3 are V-shaped, which are formed by welding or bending steel plates. The two wings of the discharging baffle 4 and the cleaning scraper 3 are supported by a support plate 21 to prevent deformation. The support plate 21 is connected to the lifting frame 2 through a suspension rod for convenient connection. The support plate 21 is V-shaped, and a buffer spring 22 is also installed between the support plate 21 and the lifting frame 2 to elastically connect the support plate 21 and the lifting frame 2, so as to control the interaction force between the cleaning scraper 3, the discharging baffle 4 and the conveyor belt 14 and ensure the stability of discharging and cleaning.

[0021] There are also reserved discharge openings on the gantry 1 that cooperate with the plow plates. There are two discharge openings, and the two discharge openings are distributed on both sides of the belt conveyor body, corresponding to the plow plates. A discharge pipe 12 is installed at the discharge opening to guide the discharge and can also suppress dust.

[0022] A support frame 16 for supporting the conveyor belt 14 is also installed on the gantry 1. A horizontal top plate is installed at the position corresponding to the plow plate on the support frame 16 to support the conveyor belt 14 during discharging. The lifting frame 2 is connected with an inclined idler 11 that cooperates with the conveyor belt 14. Specifically, the lifting frame 2 is connected with a lifting plate 18. The lifting plate 18 is located outside the gantry 1 and on both sides of the discharge opening. A guide plate 19 that cooperates with the lifting plate 18 is installed on the gantry 1. A guide groove is formed between the guide plate 19 and the gantry 1. The side end of the lifting plate 18 is inserted into the guide groove to guide the lifting plate 18. The inclined idler 11 is installed on the lifting plate 18.

[0023] For the side discharge device of the belt conveyor provided in this embodiment, the working principle of the side discharge device is as follows.

[0024] Under normal conditions, the lifting frame 2 drives the plow plate to be in a high position, and the plow plate is separated from the conveyor belt 14. At the same time, the lifting frame 2 drives the inclined idler 11 to be in a high position through the lifting plate 18. The inclined idler 11 supports both sides of the conveyor belt 14, making the cross-section of the conveyor belt 14 in a V shape to realize the normal feeding of the conveyor belt 14.

[0025] During discharging, the lifting frame 2 drives the plow plate to descend to a predetermined position. At the same time, the lifting frame 2 drives the inclined idler 11 to descend through the lifting plate 18. The inclined idler 11 is separated from the conveyor belt 14. The conveyor belt 14 is supported by the support frame 16, and the conveyor belt 14 at the position corresponding to the plow plate is supported by the top plate. The conveyor belt 14 at this position is in a straight shape. The discharge baffle 4 blocks the upper layer of the material 13 and pushes it out through the discharge opening. The lower layer of the material 13 passes under the discharge baffle 4 and enters the cleaning scraper 3. The cleaning scraper 3 blocks the lower layer of the material 13 and pushes it out through the discharge opening. The lower end of the cleaning scraper 3 contacts the conveyor belt 14 to clean the conveyor belt 14 and realize local rapid discharging.

[0026] It should be noted that when using the side discharge device of the belt conveyor provided in this embodiment, multiple side discharge devices are installed on the belt conveyor body, which can realize multi-point discharging, meet the requirements of multi-channel transportation, and realize continuous transportation.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
