Description

Technical Field

[0001] The utility model relates to the technical field of crusher feeding, in particular to a self-feeding mechanism of a biomass fuel crusher. Background Art

[0002] Biomass fuel refers to the burning of biomass materials as fuel, which are generally mainly agricultural and forestry waste. In the process of making biomass fuel, a crusher is first needed to crush various raw materials for subsequent extrusion and drying processes. Since the feed port of the crusher is at a high height, in order to improve the crushing efficiency of the raw materials, the staff will use an inclined conveyor belt to automatically feed the raw materials.

[0003] At present, the overall structure of the existing feeding conveyor belt is relatively simple during use. When the conveyor belt is used for feeding outdoors, since the conveyor belt is set to an inclined state, when encountering strong winds, some lighter raw materials on the conveyor belt are easily blown away by the wind, so manpower is needed to collect the fallen raw materials, which will increase the labor intensity of the staff. For this reason, we propose a self-feeding mechanism of the biomass fuel crusher to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a self-feeding mechanism for a biomass fuel crusher.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 The self-feeding mechanism of the biomass fuel crusher includes a crushing body 1, a feed port 2 is provided at the top of the crushing body 1, and a conveyor belt 3 is distributed on the side of the crushing body 1. The working principle of the crushing body 1 and the conveyor belt 3 is the existing technology and will not be repeated here. A protective cover 4 is connected to the upper side of the conveyor belt 3, and a feed hopper 5 is arranged inside the protective cover 4. The protective cover 4 covering the upper side of the conveyor belt 3 can protect the material during the transportation process. A slot 7 is provided inside the protective cover 4, and a transparent plate 8 is installed inside the slot 7. The transparent plate 8 installed inside the slot 7 can facilitate the staff to check the transportation status of the material.

[0023] Further, see Figure 3 and Figure 4 It can be known that the lower side of the protective cover 4 is symmetrically distributed with mounting plates 16, and there are two groups of mounting plates 16. The other group of mounting plates 16 is connected to the top of the conveyor belt 3. The upper and lower groups of mounting plates 16 are connected by bolts. When in use, the protective cover 4 and the conveyor belt 3 can be disassembled and assembled by the setting of the upper and lower groups of mounting plates 16, so that the staff can separate the protective cover 4 and the conveyor belt 3 in time, thereby facilitating the staff to repair the conveyor belt 3.

[0024] Further, see Figure 4 It can be known that positioning rods 17 are symmetrically connected at the corners of the bottom end of the protective cover 4, and the inner wall of the conveyor belt 3 is provided with positioning grooves compatible with the positioning rods 17. In the process of docking and installing the protective cover 4 and the conveyor belt 3, the protective cover 4 can be initially positioned through the mutual cooperation of the positioning rods 17 and the positioning grooves, thereby facilitating the subsequent docking and fixing by bolts by the staff.

[0025] Further, see Figure 1 and Figure 3It can be seen that a dust cover 6 is engaged on the upper side of the feed port 2, and the side of the dust cover 6 is connected to the protective cover 4. By setting the dust cover 6, the feed port 2 can be covered to prevent the material from scattering during the feeding process of the conveyor belt 3.

[0026] Further, see Figure 2 and Figure 4 It can be known that the inner wall of the protective cover 4 is provided with a moving bar 9, and a rubber strip 10 is glued on the top of the moving bar 9, the side of the moving bar 9 is connected to a moving rod 11, and the other end of the moving rod 11 extends to the outside of the protective cover 4 and is connected to a moving block 12. When in use, through the cooperation between the moving rod 11 and the moving block 12, it is convenient for the staff to pull the moving bar 9 to slide inside the protective cover 4, and the rubber strip 10 set with rubber material can prevent the transparent plate 8 from being worn.

[0027] Further, see Figure 2 It can be known that the inner wall of the protective cover 4 is connected to a guide rod 15, and a moving groove adapted to the guide rod 15 is opened inside the moving bar 9. When in use, the moving bar 9 can be guided by the mutual cooperation of the guide rod 15 and the moving groove to ensure the stable sliding of the moving bar 9.

[0028] Further, see Figure 2 It can be known that a connecting spring 14 is provided on the outer side of the moving rod 11, and one end of the connecting spring 14 is connected to the moving bar 9, and the other end of the connecting spring 14 is connected to the inner wall of the protective cover 4. The inner wall of the protective cover 4 below the connecting spring 14 is connected to a protective plate 13, and the protective plate 13 is arranged as an L-shaped structure. The protective plate 13 arranged by the L-shaped structure can protect the connecting spring 14 to prevent the material from entering the connecting spring 14. In combination with the connecting spring 14 arranged on the outer side of the moving rod 11, the rubber strip 10 can be driven to reset.

[0029] Working principle: When the utility model is used, the staff can first install the device at a suitable position, and then pour the material to be crushed into the inside of the feed hopper 5. By starting the conveyor belt 3, the poured material can be automatically put into the feed port 2. During the conveying process of the conveyor belt 3, the protective cover 4 can be set to surround the upper side of the conveyor belt 3 to effectively prevent the material from being blown away by the wind during the conveying process. The transparent plate 8 set inside the protective cover 4 can facilitate the staff to check the conveying situation of the material. When the inner wall of the transparent plate 8 is adhered to the material When cleaning the material, the staff can manually pull the moving block 12, thereby driving the moving rod 11 and applying force at the same time, so that the moving bar 9 slides inside the protective cover 4, and the rubber strip 10 connected to the top of the moving bar 9 is constantly in contact with the inner wall of the transparent plate 8 to realize the cleaning operation of the transparent plate 8. After the cleaning is completed, the staff stops pulling the moving block 12. At this time, the rubber strip 10 can be reset by the elastic force of the connecting spring 14, so that the rubber strip 10 is again in contact with the side wall of the protective cover 4 to realize the reset of the protective cover 4. The above is the entire working principle of the utility model.
