Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Such as Figure 1-7As shown in the figure, the present invention provides a rotary discharging device, including a base 1. Above the base 1, a connecting block 2 and a fixing block 3 are respectively arranged on the left and right. Above the connecting block 2, a chute body 4 is fixedly connected. The chute body 4 is of a double-layer cylindrical structure. Inside the chute body 4, a pair of deep groove ball bearings 5 and a thrust ball bearing 6 are installed to respectively bear the radial load and axial load of the system. The chute body 4 is connected to a driven gear 7. The chute body 4 and the driven gear 7 are fixedly connected by a key 8. Oil cups 14 are arranged on the upper part and side surface of the chute body 4. Above the fixing block 3, a box body 9 is fixedly connected. Above the box body 9, a gear box body 11 is provided. Inside the gear box body 11, a driving gear 12 and a driven gear 7 are provided. The gear box body 11 is connected to the chute body 4. The driving gear 12 meshes with the driven gear. Inside the box body 9, a reduction motor 10 is provided. The output shaft 13 of the reduction motor 10 extends out of the box body 9, passes through the gear box body 11 and is fixedly connected to the driving gear 12. The driving gear 12 and the output shaft 13 are fixedly connected by a key 8. Above the chute body 4, a feed chute 15 is connected. The chute body 4 and the feed chute 15 are fixedly connected by bolts 16. Above the feed chute 15, a feed point 17 is provided.

[0022] An O-ring 18 is arranged between the outer rotating body and the inner fixed body of the chute body 4, on the bushing 19 at the bottom between the inner and outer layers of the chute body 4. Above the bushing 19, a thrust ball bearing 6 is installed. Above the thrust ball bearing 6, a pressing block 20 is provided. A gap is left in the pressing block 20. Above the pressing block 20, a deep groove ball bearing 5 is provided. At the uppermost part between the inner and outer layers of the chute body 4, an installation groove 21 is provided. Inside the installation groove 21, a deep groove ball bearing 5 is provided. The inner diameters of the deep groove ball bearing 5 and the thrust ball bearing 6 are both smaller than the outer diameters. The installation positions of the above bearings all adopt the process of precision machining after welding to ensure the concentricity and machining accuracy of the cylinder body, reduce the friction coefficient during the rotation of the chute body 4, and reduce the radial load and axial load of the mechanism.

[0023] Both the chute body 4 and the feed chute 15 extend connection rings at the connection part. The bolts 16 are arranged in a circle on the connection ring. Above the connection ring, a support triangular frame 22 is provided. The bottom of the support triangular frame 22 is on the chute body 4 and is distributed in a circular array. There is an annular connection groove at the connection part between the chute body 4 and the gear box body 11. The gear box body 11 and the chute body 4 are slidably connected. The box body 9 and the gear box body 11 are connected at the output shaft 13, ensuring the connection and support of the chute body 4 and the feed chute 15 and that the gear box body 11 does not rotate with the chute body 4, protecting the gear from external erosion.

[0024] The output shaft 13 is connected to the driving gear 12 and then to the second shaft sleeve 23. A bearing 24 is connected to the second shaft sleeve 23. Above the bearing 24, it is pressed tightly by a bearing end cover 25. The bearing end cover 25 is fixed on the gear box body 11 to press tightly the output shaft 13 on the driving gear 12.

[0025] Above the deep groove ball bearing 5 at the bottom of the chute body 4, there is a discharge port 26. The discharge port 26 passes through the outer layer of the chute body 4 until the inner cavity. The bottom of the chute body 4 is solid.

[0026] The specific implementation method is as follows:

[0027] The unloading device is fixedly installed on the unloading platform, and the position of the receiving point 17 is positioned once. Subsequently, the reduction motor 10 is started. The reduction motor 10 drives the output shaft 13 to rotate, and then drives the connected driving gear 12 to rotate. The driving gear 12 drives the meshing driven gear 7 to rotate. The rotation of the driven gear 7 drives the chute body 4 to rotate. The inner diameters of the deep groove ball bearing 5 and the thrust ball bearing 6 installed in the chute body 4 are both smaller than the outer diameters, and they cooperate with the outer layer of the chute body 4 to rotate while the inner layer is fixed. Thus, the discharge port 26 on the chute body 4 is driven to rotate, realizing the arbitrary positioning of the discharge point in the circumferential direction in the plane space and the unloading action. An oil cup 14 is installed on the chute body 4 and an O-ring 18 is installed at the bottom, which can ensure that the device can be regularly inspected and lubricated with oil to prevent the loss of lubricating oil at the bearing.

[0028] The working principle of the present invention: Refer to Figure 1-7 , the output end of the reduction motor 10 drives the driving gear 12, which in turn drives the meshing driven gear 7. The driven gear 7 drives the chute body 4 to rotate. Thus, the discharge port 26 on the chute body 4 also rotates to realize the arbitrary positioning of the discharge point in the circumferential direction in the plane space and the unloading action. The inner diameters of the deep groove ball bearing 5 and the thrust ball bearing 6 installed in the chute body 4 are both smaller than the outer diameters, and they cooperate with the outer layer of the chute body 4 to rotate while the inner layer is fixed.
