[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Please see Figure 1-6 The present invention will describe the above technical solution in detail through the following embodiments:
[0031] In this embodiment, a groove 120 is provided on the top of the feeding platform 100, and a conveyor belt 130 is installed on the inner wall of the groove 120 to transport the fuel to be crushed.
[0032] Specifically, a crushing section is installed on the feeding platform 100, and a tilting frame 200 is installed on it. In this embodiment, the inner wall of the tilting frame 200 is rotatably connected to the crushing roller 230 through bearings. Figure 2 As shown in the positional relationship, the connecting rod 270 is rotatably connected between the rear sides of the tilting frame 200 and the outer wall of the feeding table 100 via the first rotating shaft 271. The bottom end of the connecting rod 270 is fixedly connected to the outer wall of the feeding table 100, and this part forms a fulcrum structure.
[0033] Meanwhile, the feeding platform 100 and the outer walls on both sides of the feeding platform 100 are fixedly connected by pneumatic telescopic rods 250 and non-powered telescopic rods 260. The pneumatic telescopic rods 250 and non-powered telescopic rods 260 are fixedly connected by flanges. The tilting angle of the tilting frame 200 can be adjusted by telescopic movement, which is convenient for crushing products of different specifications.
[0034] The specific application scenario of this embodiment is as follows: By setting a rotatable crushing section on the top of the feeding platform 100 and installing counterweights 210 of different weights on the top of the tilting frame 200, the crushing resistance of the biomass material can be adjusted according to the crushing difficulty, thereby facilitating the rapid crushing of biomass fuel under the action of gravity. By setting a detachable crushing tooth 232, it is convenient to replace the crushing tooth 232 individually when it is deformed or worn. In this embodiment, a cutting edge is opened on the surface of the crushing tooth 232 to accelerate the stamping and cutting of the surface of the biomass fuel, thereby improving the applicability of the equipment.
[0035] In this embodiment, limiting frames 140 are fixedly installed on the top of the left and right sides of the feeding platform 100. The limiting frames 140 are fixedly installed on the top of the side plates on both sides of the feeding platform 100. The two limiting frames 140 are used to guide the biomass fuel conveyed to the crushing roller 230. The limiting frames 140 can ensure that the biomass fuel is stably conveyed to the crushing roller 230 without splashing outward, thereby facilitating the crushing roller 230 to concentrate and crush the top of the biomass fuel.
[0036] like Figure 2 and Figure 6 The bottom outer wall of the feeding platform 100 is fixedly installed with support legs 110, and a limiting shaft 111 is fixedly installed on the outer wall of the support legs 110 on one side of the output end of the feeding platform 100. A storage compartment 300 is installed on the outer wall of one side of the output end of the feeding platform 100. The storage compartment 300 is locked to the outer wall of the output end of the feeding platform 100 by the cooperation of the limiting shaft 111 and the locking buckle 330, so that the storage compartment 300 can be locked on the outer wall of the output end of the feeding platform 100 during use, thereby preventing the storage compartment 300 from shifting under the vibration of the feeding platform 100 during operation. There are two locking buckles 330 symmetrically arranged on the left and right sides to facilitate even force distribution on both sides.
[0037] like Figure 4 and Figure 5 In this embodiment, the outer wall of the crushing roller 230 is detachably fixed with crushing teeth 232 by bolts. The crushing teeth 232 have an inverted U-shaped structure, which facilitates the installation of bolts for fixing. The bottom of the crushing teeth 232 is uniformly welded with stamping nails 233. By setting the crushing teeth 232 to work with the stamping nails 233, the biomass fuel on the top of the conveyor belt 130 can be repeatedly pressed and crushed during rotation, thereby achieving the function of crushing biomass fuel. A reduction servo motor 240 is set to control the crushing roller 230 to slowly reciprocate and press the surface of the biomass. By controlling the feeding speed of the conveyor belt 130, the conveyor belt 130 can be easily adapted to the speed of crushing biomass fuel, thereby facilitating the synchronous completion of crushing and feeding operations and improving the practicality of the equipment.
[0038] In this embodiment, a counterweight groove is provided on the top inner wall of the tilting frame 200. A counterweight block 210 is fixedly installed on the inner wall of the counterweight groove. The counterweight block 210 is fixedly connected to the top outer wall of the tilting frame 200 by bolts. By setting the counterweight groove to accommodate counterweight blocks 210 of different masses, it is convenient to crush biomass fuels of different textures and densities. Under the action of gravity, the crushing roller 230 applies gravity to the surface of the biomass fuel. Combined with the crushing teeth 232 and the stamping nails 233, it is beneficial to accelerate the crushing of biomass fuel. The slots 220 are provided to clamp and limit the feed table 100 on both sides, which improves the practicality and structural stability of the equipment.
[0039] The working principle of this utility model is as follows: the biomass fuel to be crushed for power plants is conveyed to the crushing section via conveyor belt 130. The storage bin 300 is placed at the output end of the feeding platform 100 and locked to the outer wall of the limiting shaft 111 by the latch 330 to fix the position of the storage bin 300. The biomass fuel is conveyed to the crushing roller 230. The crushing teeth 232 and the stamping nails 233 on the surface of the crushing roller 230 crush the biomass fuel. The impact force of the crushing roller 230 on the biomass fuel can be increased by the counterweight block 210, thereby improving the crushing efficiency. According to the thickness of the biomass to be crushed, the pneumatic telescopic rod 250 is activated to push the tilting frame 200 to rotate around the first rotating shaft 271 at the top of the top connecting rod 270, thereby adjusting the distance between the crushing roller 230 and the top of the conveyor belt 130. The crushed biomass fuel is conveyed to the storage bin 300 via conveyor belt 130 for storage, thereby facilitating and quickly completing the crushing operation of biomass fuel.
[0040] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0041] Furthermore, if the embodiments of this utility model involve descriptions such as "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
