[0027] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0028] The first implementation method:

[0029] See also Figure 1-Figure 7A crushing device for biomass fuel processing, comprising a feeder 1, a crusher 2, a control panel and an intelligent signal processor; the crusher 2 comprises a crusher shell 20, a crushing knife A224 and a crushing knife B225 arranged in parallel in the inner cavity of the crusher shell 20, and a telescopic rod 221 arranged on the crusher shell 20, and a filter screen B214 is obliquely installed in the inner cavity of the crusher shell 20. The function of the filter screen B214 is to filter the biomass fuel with larger particles after crushing, so as to prevent the biomass fuel from having larger particles after crushing, which is not conducive to subsequent production. The crusher housing 20 is provided with a collecting tank 210 at one side of the lower end of the filter screen B214. The collecting tank 210 is used to collect biomass fuel with larger particles. A pressure sensor is provided inside the collecting tank 210. The pressure sensor can detect the weight of unqualified biomass fuel in the collecting tank 210. An audible and visual alarm 220 is provided on the top of the collecting tank 210. A rotating motor A211 is fixed to one side of the crusher housing 20. A rotating disk B212 is fixed to the output shaft of the rotating motor A211. A rotating disk B212 is provided on one side of the rotating disk B212. A transmission rod B213 is connected, and the end of the transmission rod B213 is rotatably connected to the frame of the filter screen B214. Through the above connection, when the rotating motor A211 rotates, the turntable B212 is driven to rotate, and then the transmission rod B213 drives the filter screen B214 to perform oblique screening, thereby accelerating the filtering speed of the biomass fuel. The interior of the crusher shell 20 is horizontally slidably connected with a connecting plate A226 and a connecting plate B227. One side of the connecting plate A226 and the connecting plate B227 are fixed by a baffle B228. The connecting plate A226 and the connecting plate B227 are fixed to each other by a baffle B228. The other side of the connecting plate B227 is fixed by a baffle A222, and the crushing knife A224 and the crushing knife B225 are installed between the baffle A222 and the baffle B228. The baffle A222 is fixed to the output end of the telescopic rod 221. By arranging baffle A222, baffle B228, the crushing knife A224 and the crushing knife B225 on the periphery of the crushing knife A224 and the crushing knife B225, and arranging a structure in which the baffle A222 is fixed to the output end of the telescopic rod 221, the crushing knife can be quickly removed, saving the maintenance time of the crushing knife.

[0030] In addition, the intelligent signal processor includes a crushing knife detection module and a crushing knife moving module. The crushing knife detection module is electrically connected to the control panel, the pressure sensor and the sound and light alarm 220 respectively. Through the above connection, the crushing knife detection module will detect the crushing condition of the biomass fuel through the pressure sensor. When the weight of the large-particle crushed material produced within a certain period of time exceeds the set value (the crushing knife detection module is preset with the maximum weight of the large-particle crushed material generated by the crushing knife with normal sharpness during crushing within a certain period of time), the crushing knife detection module will determine that the sharpness of the crushing knife (the crushing knife refers to the crushing knife A224 and the crushing knife B225) is poor and needs maintenance, and control the sound and light alarm 220 to power on for alarm, and the control panel will display that the sharpness of the crushing knife is poor. The crushing knife moving module is electrically connected to the control panel, the telescopic rod 221 and the crushing knife detection module respectively. When the crushing knife detection module detects that the sharpness of the crushing knife is poor, it will also inform the crushing knife moving module, and when the operator agrees to move the crushing knife out on the control panel, the crushing knife moving module will control the telescopic rod 221 to power on and move the crushing knife out.

[0031] To sum up, when the crushing device is operating normally, the crushing knife detection module will detect the crushing condition of the biomass fuel through the pressure sensor on the collecting tank 210. When the weight of the large-particle crushed material produced within a certain period of time exceeds the set value, the crushing knife detection module will determine that the sharpness of the crushing knife is poor and the operator needs to maintain it. The crushing knife detection module will also control the sound and light alarm 220 to power on and alarm, and display it on the control panel. At the same time, it will also inform the crushing knife moving module. Only when the operator stops the operation of the crushing device and agrees to move the crushing knife out on the control panel, the crushing knife moving module will control the telescopic rod 221 to power on and move the crushing knife out.

[0032] In addition, mounting ears 231 are provided on both sides of the collecting tank 210, and the mounting ears 231 are installed on the output end of the hydraulic cylinder 232. The hydraulic cylinder 232 is fixed to the crusher housing 20. The hydraulic cylinder 232 is a multi-stage reciprocating hydraulic cylinder. The collecting tank 210 can be lifted up and dropped down by the hydraulic cylinder 232. The crusher housing 20 is provided with a secondary feed port at the top corresponding to the crushing knife B225. A slideway 1 matching the collecting tank 210 is provided at the secondary feed port at the top of the crusher housing 20. The collecting tank 210 can collect large particles of crushed materials from the secondary feed port through the slideway 1. The feed port is poured into the crusher 2 for secondary crushing. The secondary crushing module is electrically connected to multiple hydraulic cylinders 232 and pressure sensors respectively. When the secondary crushing module detects through the pressure sensor that there are a lot of large-particle crushed materials in the collection tank 210, the secondary crushing module will control the motor of the hydraulic cylinder 232 to energize, so that the collection tank 210 rises to a place on the slide, and the large-particle crushed materials will slide along the slide into the crusher 2; when the secondary crushing module detects through the pressure sensor that there are no large-particle crushed materials in the collection tank 210, it will also move the collection tank 210 to the original position through the hydraulic cylinder 232.

[0033] In addition, a secondary discharge port is provided at a position of the crusher shell 20 corresponding to the collecting tank 210, and the filter screen B214 conveys the large-particle crushed material to the collecting tank 210 through the secondary discharge port. A finished product discharge port is provided below the secondary discharge port, and a conveyor belt 233 is provided in the finished product discharge port. The conveyor belt 233 is provided below the filter screen B214. The small-particle crushed material screened by the filter screen B214 will fall onto the conveyor belt 233 and be conveyed out of the crusher 2 under the action of the conveyor belt 233.

[0034] In addition, a slideway 2 is provided on the crusher shell 20 to match the movement of the filter screen B214. The slideway 2 guides the movement of the filter screen B214. The axis of the rotating motor A211 is set on the extension line of the filter screen B214. This setting is to allow the rotating force of the rotating motor A211 to be better converted into the oblique running force of the filter screen B214, which is beneficial to the long-term operation of the device.

[0035] In addition, the rotating shaft of the crushing knife A224 is connected to the output shaft of the rotating motor B223, and the crushing knife B225 and the crushing knife A224 are installed with a hinged gear 229 on the same side. Through the above connection, the rotating motor B223 will drive the crushing knife A224 to rotate. Since the crushing knife B225 and the crushing knife A224 are installed with a hinged gear 229 on the same side, the crushing knife A224 will drive the rotating motor B223 to rotate in the opposite direction.

[0036] The second implementation method:

[0037] See also Figure 8 and Fig. 9 Different from the first embodiment, the feeder 1 includes a feeder housing 10, a motor A112, and a conveying cylinder 111 arranged on the output end of the motor A112. A conveying housing 113 is arranged around the conveying cylinder 111. The rotation of the conveying cylinder 111 will help the biomass fuel to enter the crusher 2, thereby improving the working efficiency of the crusher 2. A plurality of driving rollers 122 are arranged in the feeder housing 10, and a filter screen A121 is arranged on the plurality of driving rollers 122. The function of the filter screen A121 is to filter stones and sand that may be contained in the biomass fuel. A motor B123 is also arranged on the feeder housing 10. The output shaft of the motor B123 is fixed to one of the driving rollers 122. By driving the driving roller 122 by the motor B123, the rotation of the filter screen A121 can be realized, and finally the biomass fuel placed on the filter screen A121 will be transported to the crusher 2 for crushing.

[0038] In addition, a plurality of support columns 131 are arranged below the feeder housing 10, each support column 131 is provided with a motor C132, a turntable A133 is arranged on the output shaft of each motor C132, one end of each turntable A133 is rotatably connected to a transmission rod A134, and the other end of each transmission rod A134 is rotatably connected to the outer wall of the feeder housing 10, and a protective housing is also arranged on the support columns 131 and the feeder housing 10, the above-mentioned turntable A133 and transmission rod A134 are both arranged in the protective housing, when the motor C132 is energized and rotated, it will drive the turntable A133 to rotate, and then the transmission rod A134 will convert its rotational force into the force for the feeder housing 10 to move up and down, thereby realizing the vibration of the feeder housing 10 and improving the filtering effect of the filter net A121.

[0039] To sum up, since most biomass fuels are crop straws, the purchased crop straws will inevitably contain small stones, which may damage the crushing knives in the crusher 2, or contain a certain amount of sand and soil that will affect the quality of the crushed product. Therefore, a filter screen A121 is provided in the feeder 1 to filter out stones and mud that may be contained in the crop straws. In order to achieve a good filtering effect, a motor C132 is provided in the support column 131. When the motor C132 is powered on and rotated, it will drive the turntable A133 to rotate, and then the transmission rod A134 will convert its rotational force into the force for the feeder shell 10 to move up and down, thereby realizing the vibration of the feeder shell 10, and then improving the filtering effect of the filter screen A121.

[0040] In addition, one side of the conveying shell 113 is connected to the feeder shell 10, and the other side of the conveying shell 113 is connected to the crusher shell 20. Sliding grooves are provided on the contact surfaces of the feeder shell 10 and the crusher shell 20 with the conveying shell 113. Since the sizes of the biomass fuels on the filter screen A121 are different, the conveying cylinder 111 will have different degrees of ups and downs when passing through. Through the guidance of the conveying shell 113, the feeder shell 10 and the crusher shell 20, the conveying cylinder 111 can have a stable ups and downs effect.

[0041] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
