[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-2 The utility model provides the following technical solutions: a long-life sintering machine round roller feeding device, comprising a mixture trough 1 and a round roller feeding machine 2, wherein the mixture trough 1 is arranged above the round roller feeding machine 2 and connected by an elastic seal to prevent the mixture from overflowing, and the elastic seal is made of rubber. A hinged door 3 is installed at the discharge port of the mixture trough 1, and the hinged door 3 is connected to the mixture trough 1 by hinges. The switch and opening adjustment of the hinged door 3 are controlled by a power device 4, and the power device 4 adopts a cylinder or an electric cylinder. The surface of the round roller feeding machine 2 is evenly provided with wear-resistant ribs 5 by a laser cladding process. In this embodiment, by setting a power device 4 to control the hinged door 3, the gap between the hinged door 3 and the round roller feeding machine 2 can be stabilized, so that the mixture in the mixture trough 1 can be evenly discharged. The wear-resistant ribs 5 are arranged on the surface of the round roller feeding machine 2, and the friction force is increased by its own rough contact surface to ensure that the mixture can be stably fed under extreme conditions. The mixed material trough 1 cooperates closely with the hinged door 3 and the round roller distributor 2, so that the mixed material can be discharged smoothly from the gap between the hinged door 3 and the round roller distributor 2.

[0016] As a preferred implementation of this embodiment, the wear-resistant ribs 5 are arranged in parallel and at equal intervals on the surface of the round roller distributor 2, and the cross section is semicircular. The wear-resistant ribs 5 are made of Ni, Cr, Mo, and Ti materials as basic components, and are fine-tuned according to the common material conditions. The height of the wear-resistant ribs 5 is 10mm, the width is 15mm, and the spacing between adjacent wear-resistant ribs 5 is 15mm. The wear-resistant ribs 5 have a high straightness, which can ensure that the sintering machine trolley feeds the material consistently in the width direction, improve the uniformity of the material distribution, and during the processing, the round roller distributor 2 is placed on a large rotating roller, and the laser cladding process is used for additive processing.

[0017] As a preferred implementation of this embodiment, the external fixing mounting plate 6 of the mixed material trough 1, the fixed end of the power device 4 is fixed to the mounting plate 6, and the movable end of the power device 4 is connected to the hinged door 3. A stabilizing plate 7 is also included, one end of which is connected to the external part of the mixed material trough 1, and the other end is connected to the mounting plate 6.

[0018] By adopting the long-life sintering machine round roller feeding device of this embodiment, when the moisture content of the mixture in the mixture trough 1 fluctuates greatly, the stability and active directional adjustment of the feeding system can be ensured; at the same time, the wear resistance of the system is doubled compared with the traditional stainless steel liner, which not only improves the production efficiency and reduces the production cost, but also reduces the spare parts maintenance rate and reduces the labor intensity of maintenance workers.

[0019] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
