[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] like Figure 1 As shown, the present application provides a boiler feeding device, including an elevator, which is suitable for conveying fuel, and the elevator includes a casing 1, and a pulley 11 fixedly installed on the lower surface of the casing 1, and a conveyor belt 2 is installed inside the casing 1, and a material receiving trough plate 3 is fixedly installed on the conveyor belt 2, and a storage hopper 4 is also fixedly installed on the upper surface of the casing 1, wherein the pulley 11 is used to move the feeding elevator as a whole, the material receiving trough plate 3 is used to convey the fuel in the storage hopper 4, and the storage hopper 4 is used to store fuel;

[0025] At the same time, a driving device (not shown in the figure) supporting the operation of the elevator is arranged inside the casing 1, and the driving mechanism is used to drive the conveyor belt 2 to continuously convey. In the present application, the driving mechanism and the conveyor belt 2 can constitute a complete belt conveyor mechanism, and the belt conveyor mechanism is a prior art, and its specific structure and principle are not repeated here;

[0026] A discharge hopper 5 is also fixedly mounted on the casing 1, and the outlet of the discharge hopper 5 can be located at the upper end of the boiler, so that the fuel on the belt conveyor mechanism can be input into the boiler through the discharge hopper 5;

[0027] In summary, when the elevator is in normal use, the fuel is first stored in the storage hopper 4, and the elevator is started, and the fuel is transported from the discharge hopper 5 to the boiler through the operation of the belt conveyor mechanism, so as to realize continuous fuel loading;

[0028] In this application, the elevator is an ordinary loading elevator. The above is just a brief description of the basic working principle of the loading elevator. For the specific working principle, please refer to relevant literature and will not be repeated here.

[0029] During the use of the elevator, since the outlet size of the discharge hopper 5 is fixed, when loading boilers of different sizes, the fuel may easily spill out from the boiler furnace port;

[0030] In order to solve the above problems, the present application describes a feeding device, which can further improve the applicability of the elevator, specifically:

[0031] like Figure 2-Figure 3 As shown, a sleeve plate 51 is sleeved and installed on the outer surface of the discharge hopper 5, and the sleeve plate 51 is fixedly installed with the casing 1. At the same time, a telescopic cylinder 53 is fixedly installed on the four sides of the discharge hopper 5. The outer surface of the telescopic cylinder 53 is covered with a protective cover 531, and the lower surface of the protective cover 531 is provided with an open groove 532. At the same time, the protective cover 531 is fixedly installed on the side of the discharge hopper 5, and the protective cover 531 is also used to protect the telescopic cylinder 53.

[0032] A side plate 54 is fixedly mounted at the output end of the telescopic cylinder 53, and an adjusting inclined plate 541 is fixedly mounted on the lower surface of the side plate 54. The placement angle of the adjusting inclined plate 541 is consistent with the side inclination of the discharge hopper 5. The adjusting inclined plate 541 is used to adjust the size of the discharge opening of the discharge hopper 5.

[0033] In the initial state, the adjusting inclined plates 541 are moved by the telescopic cylinder 53 and are attached to the side of the discharge hopper 5. When necessary, the four sets of adjusting inclined plates 541 are pushed to the bottom of the discharge hopper 5 by the telescopic cylinder 53. As the adjusting inclined plates 541 move downward, the discharge openings formed at the lower ends of the four sets of adjusting inclined plates 541 gradually decrease until they meet the size of the boiler.

[0034] In the present application, the size of the fuel particles is generally large, so that during the downward movement of the four sets of adjusting inclined plates 541, although there are gaps between the adjusting inclined plates 541, the fuel particles will not leak out from the gaps;

[0035] In summary, when the elevator is in use, when loading boilers of different sizes, the discharge hopper 5 can receive the fuel in the receiving trough plate 3 on the conveyor belt to prevent the fuel from spilling during the unloading process;

[0036] Then, by starting the telescopic cylinder 53, the output end of the telescopic cylinder 53 pushes the side plate 54, and the side plate 54 pushes the adjusting inclined plate 541 to move downward, so that the size of the discharge port formed at the lower end of the four sets of adjusting inclined plates 541 can be adjusted, so that when loading the boiler, fuel spillage is avoided, and it is suitable for loading boilers of different sizes in the same workshop.

[0037] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
