Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a biomass fuel crusher. Background Technology

[0002] Biomass fuel refers to the combustion of biomass materials as fuel, which are generally agricultural and forestry wastes such as straw, rice husks, and sawdust. These wastes are processed through crushing, extrusion, and drying to produce various block and granular forms.

[0003] A search revealed Chinese patent CN207151265U, which discloses a small-scale biomass fuel crushing device. This device includes a closed crushing chamber, the internal cavity of which is divided by a partition plate into a primary crushing chamber at the upper end and a secondary crushing chamber at the lower end. The aforementioned patent's small-scale biomass fuel crushing device has the following shortcomings: the residence time of agricultural and forestry waste in the crushing chamber is relatively short, and some materials may not have sufficient time to fully contact and interact with the crushing blades. For example, straw has a certain degree of toughness; if it does not stay in the crushing chamber for a sufficiently long time, some straw segments will only be simply cut without being crushed into suitable particle sizes. This may result in a significant variation in the size of the final biomass fuel particles, failing to meet the requirement of uniform particle size for high-quality biomass fuel. Therefore, we propose a biomass fuel crusher to solve the above problems. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-5As shown, this utility model provides a biomass fuel crusher, including a fixed frame 1. A drive component 101 is installed on one side of the top of the fixed frame 1. A connecting belt 103 is sleeved on the output end of the drive component 101. A pulley 104 is sleeved on the end of the connecting belt 103 away from the drive component 101. A fixed shell 102 is installed on the surface of the connecting belt 103. A control component 2 is provided on the other side of the top of the fixed frame 1. The control component 2 includes a crushing cylinder 201. The bottom of the crushing cylinder 201 is fixedly connected to the side of the fixed frame 1 away from the drive frame. A feed inlet 203 is opened at the top of the crushing cylinder 201. A discharge chamber door 204 is installed at the bottom of the crushing cylinder 201. A drive roller 2 is sleeved on one end of the crushing cylinder 201. 02. The end of the drive roller 202 away from the crushing cylinder 201 is fixedly connected to the pulley 104. A limiting ring 205 is sleeved on the surface of the drive roller 202. A matching limiting groove 206 is opened at the end of the crushing cylinder 201 near the limiting ring 205. The inner ring wall of the limiting ring 205 is fixedly connected to the drive roller 202. The outer ring wall of the limiting ring 205 is rotatably connected to the groove wall of the limiting groove 206. A cutter 217 is fixedly connected to the surface of the assembly roller 208. After the drive component 101 on one side of the top of the fixed frame 1 is started, its output end transmits power to the pulley 104 through the sleeved connecting belt 103. The pulley 104 is fixedly connected to the drive roller 202, thereby driving the drive roller 202 to rotate. The rotation of the drive roller 202 will further drive the operation of the associated components to achieve the crushing and processing of biomass fuel. The assembly roller 208 is fixedly connected to the surface of the cutter 217. As the drive roller 202 rotates, it drives the assembly roller 208 and the cutter 217 to rotate together, thereby achieving the initial crushing and cutting action of the biomass fuel entering the crushing cylinder 201.

[0024] Furthermore, a telescopic spring 207 is sleeved at one end of the drive roller 202 located inside the crushing cylinder 201. An assembly roller 208 is sleeved at the end of the telescopic spring 207 away from the drive roller 202. Multiple evenly distributed guide windows 209 are opened at the end of the assembly roller 208 near the drive roller 202. A guide seat 210 is built into each guide window 209 and is slidably connected to the inner wall of the guide seat 210. A connecting plate 211 is fixedly connected to the end of the guide seat 210 near the axis of the assembly roller 208. The end of the connecting plate 211 away from the guide seat 210 is fixedly connected to the drive roller 202. One end of the moving roller 202 is fitted with a connecting disc 212. The inner ring wall of the connecting disc 212 is fixedly connected to the assembly roller 208. Multiple top seats 213 are fixedly connected to the side of the connecting disc 212 away from the driving roller 202. The multiple top seats 213 are evenly distributed around the axis of the connecting disc 212. One end of the top seat 213 is an elliptical head 214. One end of the inner wall of the crushing cylinder 201 is fixedly connected with a fixed disc 215. Multiple embedding grooves 216 matching the elliptical head 214 are opened on the surface of the fixed disc 215. One end of the driving roller 202 located inside the crushing cylinder 201 is fitted with a telescopic spring 207. The other end of the telescopic spring 207 is fitted with the assembly roller 208. The assembly roller 208 has multiple evenly distributed guide windows 209 at one end near the drive roller 202. The guide seat 210 inside the guide window 209 is slidably connected to the inner wall of the window. The guide seat 210 is fixed to the drive roller 202 through the connecting plate 211. This allows the assembly roller 208 to move relative to the drive roller 202 within a certain range, and can achieve actions such as extension and resetting under the action of the telescopic spring 207.

[0025] Multiple top seats 213, each with an elliptical head 214, are fixed on a connecting disc 212 sleeved at the end of the assembly roller 208 away from the drive roller 202. These top seats are evenly distributed around the axis of the assembly roller 208. A fixed disc 215 is fixed to one end of the inner wall of the crushing cylinder 201, and the surface of the fixed disc 215 has an embedding groove 216 that matches the elliptical head 214. When the cutter 217 rotates with the assembly roller 208 to crush the material, the top seats 213 move into and away from the embedding groove 216 as the assembly roller 208 rotates. Due to the interaction between the top seats 213 and the embedding groove 216, the assembly roller 208 can drive the cutter 217 to move laterally repeatedly. This ensures that the biomass fuel in the crushing cylinder 201 is not only subjected to the rotational cutting of the cutter 217 but also to the cutting and tearing effects caused by the lateral movement of the cutter 217, thus greatly enhancing the crushing effect.

[0026] The rotating crushing of the cutter 217 and its lateral movement crushing in conjunction with the top seat 213 and the embedded groove 216 create a multi-dimensional crushing effect on biomass fuel. Compared with traditional crushers that rely solely on single rotating cutting, this method can crush biomass fuel into finer and more uniform particles, thus improving the crushing quality.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
