[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a biomass fuel crushing device. Figure 1 and Figure 2 A biomass fuel crushing device includes a rectangular hollow shell 1, and a bucket-shaped feed opening 2 is fixedly connected to the upper surface of the shell 1, and two crushing rollers 3 are rotatably connected to the inner side wall of the shell 1, and one end of the crushing roller 3 penetrates the shell 1 to its side surface and is fixedly connected to the output end of the motor, so that the biomass fuel is poured into the device from the feed opening 2, and then falls between the two crushing rollers 3, and the two crushing rollers 3 are driven by the motor to rotate relative to each other to crush them, and a mesh plate 4 is slidably connected to the inner wall of the shell 1 below the two crushing rollers 3. The mesh of the mesh plate 4 is relatively small, so that after the biomass fuel is crushed by the crushing roller 3, the larger biomass fuel that is not sufficiently crushed can stop on the upper surface of the mesh plate 4, and then be secondary broken by the rotation of the crushing roller 3, so that the biomass fuel can be fully crushed, the crushing efficiency and quality can be improved, and the subsequent processing is convenient. A box-shaped material receiving box 5 is slidably connected to the inner wall of the shell 1 below the mesh plate 4, so that the fully crushed biomass fuel falls downward through the mesh of the mesh plate 4 into the material receiving box 5 for storage, so as to be used for subsequent processing;

[0023] Secondly, a rectangular cavity-shaped negative pressure vacuum cleaner 6 is fixedly connected to the side surface of the shell 1, and a square groove-shaped mounting groove 7 is opened on the side surface of the discharge port 2, and a box-shaped dust box 8 is fixedly connected to the inner wall of the mounting groove 7, and a tubular conveying pipe 9 is fixedly connected to the side surface of the dust box 8, and the other end of the conveying pipe 9 is fixedly connected to the upper surface of the negative pressure vacuum cleaner 6, so that under the negative pressure of the negative pressure vacuum cleaner 6, dust can be absorbed through the dust box 8 and the conveying pipe 9, so as to effectively absorb the dust generated when the biomass fuel is put in and the dust generated when it is crushed, so as to avoid affecting the surrounding environment and personnel health.

[0024] Reference Figure 2 and Figure 3 A groove-shaped through slot 11 is formed through the side surface of the housing 1, and a vibration motor 12 is fixedly connected to the inner wall of the through slot 11, and the output end of the vibration motor 12 is fixedly connected to the side surface of the mesh plate 4, so that when the crushing work is performed, the mesh plate 4 is driven to vibrate up and down by the vibration motor 12, thereby accelerating the speed at which the crushed biomass fuel passes through the mesh plate 4, and can avoid blockage, thereby ensuring the smooth progress of the crushing work;

[0025] At the same time, two plate-shaped support plates 13 are fixedly connected to the two inner side walls of the shell 1, and a plurality of telescopic columns 14 and a plurality of return springs 15 are fixedly connected to the opposite side surfaces of the two support plates 13, and the other ends of the plurality of telescopic columns 14 and the plurality of return springs 15 are fixedly connected to the upper surface and the lower surface of the grid plate 4, so that when the grid plate 4 vibrates, the vibration of the grid plate 4 can be buffered by the telescopic effect of the telescopic columns 14 and the return effect of the return springs 15, so as to reduce the influence of the vibration of the grid plate 4 on the shell 1 and ensure the service life of the device.

[0026] Reference Figure 4 A baffle 10 is connected to the side surface of the discharge port 2 so as to prevent the biomass fuel from being sucked into the dust box 8 during discharge, thereby blocking the delivery pipe 9 and affecting the smooth progress of the crushing and dust collection work, thereby avoiding reducing the working efficiency of the device;

[0027] An arc-shaped groove 16 is provided on the upper surface of the baffle 10, and a groove-shaped limiting groove 17 is provided on the side surface of the discharge port 2. A block-shaped limiting block 18 is elastically slidably connected to the inner wall of the limiting groove 17 through a spring, and the limiting block 18 can be engaged with the inner wall of the groove 16 so that the baffle 10 can be quickly and stably fixed, so that when the baffle 10 needs to be cleaned or replaced, the disassembly and installation of the baffle 10 can be completed quickly, thereby ensuring the working efficiency of the device.

[0028] The implementation principle of a biomass fuel crushing device in an embodiment of the present application is as follows: the biomass fuel is poured into the device from the feed port 2, and then falls between the two crushing rollers 3, and the two crushing rollers 3 are driven by a motor to rotate relative to each other to crush it, and then the mesh plate 4 is driven by a vibration motor 12 to vibrate up and down, so that the biomass fuel fragments that are broken into small pieces fall downward through the mesh of the mesh plate 4 into the receiving box 5 for storage for subsequent processing and use, and the larger biomass fuel that is not sufficiently crushed will stop on the upper surface of the mesh plate 4, and then be broken again by the rotation of the crushing rollers 3, so that the biomass fuel can be fully crushed, the crushing efficiency and quality can be improved, and subsequent processing can be facilitated. At the same time, under the negative pressure of the negative pressure vacuum cleaner 6, dust is absorbed by the dust box 8, so that the dust generated when the biomass fuel is put in and the dust generated when it is crushed can be effectively absorbed to avoid affecting the surrounding environment and personnel health and improve safety.
