[0002] Biofuel refers to solid, liquid or gaseous fuels composed of or extracted from biomass. It can replace gasoline and diesel made from petroleum and is an important direction for the development and utilization of renewable energy. The so-called biomass refers to various organisms produced by photosynthesis using the atmosphere, water, land, etc., that is, all living organic matter that can grow, including plants, animals and microorganisms. Different from traditional fuels such as oil, coal, and nuclear energy, this emerging fuel is a renewable fuel. In response to the country's call for energy conservation and environmental protection, heating plants mostly use biomass fuel boilers. Biomass fuel is only available when biological boilers are working. It uses renewable biofuels as fuel. Biofuels are made of wood chips, bamboo chips, straw, glue, etc., turning waste into treasure and causing little pollution to the environment.

[0003] In the prior art, due to the large base mixture of biomass combustion raw materials such as wood chips, bamboo chips and straw, the feeding hopper is often blocked during the feeding process, thereby affecting the feeding time of the biofuel. At the same time, the current feeding device for biomass boiler fuel has a too fixed structure and cannot be assembled with different types of bioboilers, resulting in poor overall practicality. In view of the above problems, the inventor proposes a special feeding device for biomass boilers to solve the above problems. Utility Model Content

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.

[0020] Example: Figure 1-4As shown, the utility model provides a technical solution: a special unloading device for a biomass boiler, comprising a bottom plate 1, a hydraulic telescopic column 11 is fixedly connected to the top of the bottom plate 1 near the corner, a top column 12 is fixedly connected to the top of the hydraulic telescopic column 11, a crushing box 2 is fixedly connected between the four top columns 12, a discharge box 21 is fixedly connected at the center of the bottom end of the crushing box 2, a crushing roller 34 is symmetrically rotatably connected between the side walls of the crushing box 2 near the center, a vertical plate 1 22 is symmetrically fixedly connected to the two side ends of the discharge box 21 near the bottom, a vertical plate 23 is symmetrically fixedly connected to the side end of the crushing box 2 near the center, a conveyor belt 24 is installed between the two vertical plates 23 and the two vertical plates 1 22, and the conveyor belt 24 is installed obliquely, and connecting plates 25 are symmetrically fixedly connected to the opposite ends of the two vertical plates 23 and below the conveyor belt 24, a unloading port 26 is fixedly connected between the two connecting plates 25, and a unloading cover 28 is provided below the unloading port 26.

[0021] L-shaped plates 29 are symmetrically fixedly connected to both side ends of the lower material cover 28 .

[0022] By adopting the above technical solution, the second L-shaped plate 29 is provided to cooperate with the first L-shaped plate 27 to achieve the fixing operation of the material lowering cover 28.

[0023] The bottom ends of the two connecting plates 25 are symmetrically fixedly connected with L-shaped plates 1 27 near the lower material cover 28, and the L-shaped plates 1 27 and the L-shaped plates 29 are at the same level.

[0024] By adopting the above technical solution, the L-shaped plate 1 27 and the L-shaped plate 2 29 are detachably connected by bolts, so that the material cover 28 of different models and sizes can be disassembled and replaced.

[0025] A top cover is fixedly connected between the inner walls of the crushing box 2 and near the top, and the top cover is trapezoidal in shape.

[0026] By adopting the above technical solution, a top cover is arranged between the inner walls of the crushing box 2 near the top to prevent the material from splashing outwards when being crushed.

[0027] The side end of the crushing box 2 is symmetrically connected to the bevel gear 13 near the center, and one end of the crushing roller 34 passes through the crushing box 2 and is fixedly connected to the bevel gear 13.

[0028] By adopting the above technical solution, the bevel gear 3 rotates, thereby causing the fixedly connected crushing roller 34 to rotate, thereby achieving the crushing of the raw materials.

[0029] Support plates 31 are symmetrically fixedly connected to the side ends of the crushing box 2 and close to the center, and a rotating shaft 32 is rotatably connected between the two support plates 31.

[0030] By adopting the above technical solution, two support plates 31 are provided to support the rotating shaft 32, so as to achieve the effect of driving the bevel gear 1 3 to rotate.

[0031] A bevel gear 2 33 is symmetrically fixedly connected to the outer ring of the rotating shaft 32 and close to the bevel gear 1 3 , and the bevel gear 2 33 is meshed with the bevel gear 1 3 .

[0032] By adopting the above technical solution, the rotating shaft 32 rotates, so that the two fixedly connected bevel gears 2 33 rotate at the same time, thereby making the meshingly connected bevel gears 1 3 rotate at the same time.

[0033] A motor 35 is fixedly mounted on one end of one of the support plates 31 away from the rotating shaft 32 , and an output end of the motor 35 passes through the support plate 31 and is fixedly connected to the rotating shaft 32 .

[0034] By adopting the above technical solution, the motor 35 is operated so that the fixedly connected rotating shaft 32 is rotated.

[0035] Working principle: When the device is in use, the biomass combustion raw materials are first poured into the crushing box 2, and then the motor 35 is operated, so that the fixedly connected rotating shaft 32 is rotated, so that the two fixedly connected bevel gears 2 33 are rotated at the same time, and at this time, the two bevel gears 1 3 meshingly connected therewith will drive the two fixedly connected crushing rollers 34 to rotate towards each other at the same time, thereby achieving the effect of crushing the combustion raw materials, and then they fall onto the conveyor belt 24 through the discharge box 21, and with the cooperation of the conveyor belt 24, the raw materials fall into the boiler through the discharge port 26 and the discharge cover 28, thereby solving the problem that the basic mixture of biomass combustion raw materials such as sawdust is large, which often causes the phenomenon of clogging in the discharge hopper during the discharge process;

[0036] When the feed inlet of the working boiler is small, the two L-shaped plates 29 are removed from the L-shaped plate 1 27, and the smaller feed cover 28 is placed under the feed inlet 26. Then, the fixed limit feed cover 28 is achieved through bolts and the cooperation between the two groups of L-shaped plates 1 27 and L-shaped plates 2 29. If the boiler is low, the four hydraulic telescopic columns 11 are operated at the same time, and then with the cooperation of the four top columns 12, the crushing box 2 drives one side of the mechanism to descend, and the feed cover 28 is in contact with the boiler mouth, so as to achieve the work of feeding boilers of different models and sizes, thereby solving the problem that the feed device of the bio-boiler fuel is too fixed in structure and cannot be assembled with bio-boilers of different models.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
