The invention relates to the technical field of agricultural machinery, in particular to an agricultural waste harvesting, smashing and compressing all-in-one machine and a working method. The all-in-one machine comprises a harvesting mechanism used for harvesting waste, a smashing mechanism and a compressing mechanism. The crushing mechanism comprises a crushing bin as well as a feeding pressing shaft, a spiral chopping cutter and a hammer sheet type crushing cutter which are positioned in the crushing bin, and the feeding pressing shaft, the spiral chopping cutter and the hammer sheet type crushing cutter are sequentially arranged in the waste conveying direction and are rotationally connected with the crushing bin; the compression mechanism comprises a compression bin communicated with the smashing bin, a compression mold disc and a compression rolling wheel are arranged in the compression bin, the compression mold disc is arranged in the middle of the compression bin, a mold hole is formed in the compression mold disc, and the compression rolling wheel is rotationally installed on the compression mold disc. According to the invention, harvesting, crushing and compression treatment of melon seedlings can be efficiently completed, the melon seedlings are converted into biofuel with high added value, and cyclic utilization of resources is realized.

This invention belongs to the field of clutch manufacturing technology and aims to solve the problem that the friction performance of existing heavy-duty clutches gradually decreases over time, thus affecting their transmission smoothness and shortening their service life. To this end, this invention provides a method for preparing a surface-textured clutch plate. The method includes: preparing a mixed powder comprising metal matrix powder, solid lubricant powder, reinforcing phase powder, and a forming agent, and mixing them uniformly in a predetermined ratio; loading the mixed powder into a mold for cold pressing to obtain a green blank with a predetermined geometric structure; sintering the green blank under a protective atmosphere with stepped heating; processing microtextures on the friction surface of the sintered part using an ultrasonic impact device; and cleaning the surface of the ultrasonically impacted workpiece. This invention can optimize the friction performance of the clutch, enabling it to maintain high friction characteristics for a long time and preventing a rapid reduction in the clutch's service life.
