[0002] Belt conveyors are used in all walks of life. They mainly play the role of conveying, lifting and unloading. Along the conveying direction of the belt conveyor, the upstream is generally the tail wheel and the downstream is generally the head wheel. You can refer to the public (announcement) number: CN211970649U, public (announcement) number: CN202754425U.

[0003] When used in industrial and mining fields, there are many flying stones. In order to prevent people or flying stones from being drawn into the machine, causing casualties and machine damage, a quarter-circular arc plate is usually set on the tail wheel for simple protection. This type of protective plate has a small protection range and can only protect the upper half of the tail wheel. There is still a serious problem of inadequate protection. Utility Model Content

[0007] The included angle a between the strap and the lower belt of the conveyor is an acute angle, and the bottom end of the strap is tangent to the top surface of the lower belt of the conveyor.

[0008] The bottom end of the butt plate has an inclined portion.

[0009] The protective device comprises two side baffles, which are respectively blocked at two sides of the semicircular plate, and the side baffles are provided with through holes.

[0010] The upper end of the semicircular plate has an upper extension plate, and the upper extension plate is arranged parallel to the upper belt of the conveyor; and / or the lower end of the semicircular plate has a lower extension plate, and the lower extension plate is arranged parallel to the lower belt of the conveyor.

[0011] A belt conveyor tail wheel protection device proposed by the utility model has the beneficial effects that: this device uses a semi-circular plate to wrap the tail wheel of the belt conveyor. Compared with the traditional quarter-circular plate, the wrapping surface of this device is increased, improving the protection range. And a latching plate is hung at the upper end of the semi-circular plate. The upper belt and the lower belt of the conveyor pass through the first through slot and the second through slot respectively. The latching plate blocks objects such as flying stones from entering above the lower belt, playing a role in protecting the tail wheel. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Refer to Figures 1 - 4 , a belt conveyor tail wheel protection device includes a semi-circular plate 1 and a latching plate 6. A pin shaft 10 with a horizontally arranged axis is installed at the upper end of the semi-circular plate 1. The top end of the latching plate 6 has a hanging ear 9, and the hanging ear 9 is rotatably connected to the pin shaft 10. There is a first through slot 7 between the upper end of the latching plate 6 and the upper end of the semi-circular plate 1, and there is a second through slot 8 between the lower end of the latching plate 6 and the lower end of the semi-circular plate 1.

[0019] Refer to Figure 1 , Figure 3 , install the protection device on the frame of the conveyor. This device uses the semi-circular plate 1 to wrap the tail wheel of the belt conveyor. Compared with the traditional quarter-circular plate, the wrapping surface of this device is increased, improving the protection range. And a latching plate 6 is hung at the upper end of the semi-circular plate 1.
