[0022] One unavoidable problem in the current process of crushing agricultural and forestry waste is that the plant debris and dust in the waste are very easy to be dispersed into the air during the crushing process, affecting the environmental quality of the work area.
[0023] To resolve the above issues, please refer to Figure 1-5 This application discloses a crushing device for treating solid waste of agricultural and forestry waste, including a crusher housing 1. The crusher housing 1 is a rectangular cavity shell that provides crushing operation space. A power assembly 2 is provided on the side of the crusher housing 1 to provide power to the equipment. A crushing roller shaft 13 is installed inside the crusher housing 1 and connected to the power assembly 2 to perform the main crushing function. A homogeneous separation assembly 3 is provided on the crusher housing 1 to realize the coordinated operation of crushing and dust removal.
[0024] The same source separation component 3 and the power component 2 work together to achieve multiple functions driven by a single power source. The same source separation component 3 effectively separates and collects the dust and debris generated during the crushing process.
[0025] The same source separation component 3 includes a separator housing 31 installed on the outside of the crusher housing 1 to collect dust-laden airflow. The bottom of the separator housing 31 is provided with an air outlet 32 to discharge purified air. The air outlet 32 is equipped with negative pressure guide vanes 33 to generate the negative pressure required by the system. The negative pressure guide vanes 33 are installed on a fixed frame to ensure stable operation. The separator housing 31 is provided with a spray component 4 to achieve wet dust removal. The spray component 4 is supplied with pressurized water by a water supply pump 41. The water supply pipe 42 connected to the water supply pump 41 delivers water. Several water supply nozzles 43 evenly distributed on the water supply pipe 42 atomize water and spray it into the separator housing 31. Several pairs of exhaust ports 34 are provided on both sides of the crusher housing 1 and are connected to the inside of the separator housing 31 to allow dust-laden air to enter the separation zone. The bottom of the separator housing 31 is provided with a slag discharge port 35 to discharge settled wet dust. The central shaft of the negative pressure guide vanes 33 is connected to the power component 2 through a gear set 36 to achieve power sharing.
[0026] As a preferred option, further, the lower end of the crusher shell 1 is the discharge port 11 for discharging crushed material, and the upper end of the crusher shell 1 is the feeding port 12 for feeding waste to be processed. The discharge port 11 and the feeding port 12 are connected by a feeding channel to form a material flow path.
[0027] As a preferred option, a pair of crushing rollers 13 are provided inside the crusher housing 1 to improve crushing efficiency. The pair of crushing rollers 13 are connected to the power assembly 2 to obtain power. Several crushing blades are provided on the crushing rollers 13 to realize the material crushing function.
[0028] As a preferred option, the power assembly 2 further includes a power motor 21 as the core power source. The power motor 21 is located on the side of the crusher housing 1. The output end of the power motor 21 is connected to a reducer 22 to adjust the output speed and torque.

[0031] Work process: After the power motor 21 starts, it drives a pair of crushing rollers 13 and gear set 36 to operate simultaneously through the reducer 22. Agricultural and forestry waste is put into the crusher shell 1 through the feed port 12 and is cut and crushed by the high-speed rotating crushing blades. The dust-laden air generated during the crushing process is drawn into the separator shell 31 through the exhaust ports 34 on both sides of the crusher shell 1 under the negative pressure of the system generated by the negative pressure guide vanes 33. Inside the separator shell 31, the water pump 41 starts and supplies water to the water supply nozzle 43 through the water supply pipe 42 to form a fine water curtain. The dust-laden air and water mist are fully mixed. The dust particles are captured by the water mist and become heavier and settle. The purified air is discharged through the air outlet 32, and the settled wet dust is discharged from the slag discharge port 35. The crushed material is output from the discharge port 11 through the feed plate. In the whole process, the crushing and dust removal functions are realized through the same power source to ensure the coordinated operation of the system.
[0032] This device effectively solves the problem of dust dispersion during the crushing of agricultural and forestry waste through the homogeneous separation component 3. Specifically, it adopts a negative pressure guide vane 33 linked with the crushing mechanism to achieve multiple functions driven by a single power source, which is energy-saving and has good coordination. The wet dust removal system captures dust particles through water mist, with high dust removal efficiency. The overall structure is reasonable, and crushing and dust removal are carried out simultaneously, which greatly improves the air quality of the working environment, reduces material loss, and improves the pretreatment efficiency and clean production level of agricultural and forestry waste.
