[0007] Preferably, the shaft, the left half roller and the right half roller are coaxially arranged.

[0008] Preferably, both the front and rear ends of the left half roller and the right half roller are provided with mounting grooves, the side walls of the mounting grooves close to the center of the rollers are provided with inclined surfaces with an inclined angle, the key roller tensioning plate is a circular ring structure, the inner side wall of the circular ring is an inclined surface, and the inclined surface of the mounting groove is arranged corresponding to the inclined surface of the key roller tensioning plate.

[0009] Preferably, the key roller tightening plate is provided with bolt through holes, and the left half roller and the right half roller are correspondingly provided with threaded holes.

[0010] Preferably, the key roller tensioning plate is further provided with two threaded holes, the left half roller and the right half roller are respectively provided with a corresponding threaded hole, and the key roller tensioning plate is respectively connected to the left half roller and the right half roller by removing the threads.

[0011] The utility model has the following beneficial technical effects:

[0012] The utility model adopts a key roller tightening plate to fix two rollers on the shaft, and at the same time installs a flat key to make the roller and the shaft run synchronously. Since the roller and the tightening plate have a certain taper, they are tightly combined without any looseness. At the same time, a disassembly thread is designed, so it is easy to load and unload. Since there is no hole on the shaft, the problem of frequent shaft breakage is effectively solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments of the specification. The specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Specific implementation method 1: Combination Figures 1 to 4 The present embodiment describes a hemp stem shredding roller installation structure, which comprises a shaft 1, a left half roller 6 and a right half roller 7; the left half roller 6 and the right half roller 7 are spliced ​​and installed on the shaft 1, and a key roller tightening plate 3 is respectively provided at both ends of the left half roller 6 and the right half roller 7.

[0020] In a preferred example, the key roller tightening plate 3 is fixedly connected to the left half roller 6 and the right half roller 7 respectively through fixing bolts 4.

[0021] In a preferred example, a keyway is provided on the shaft 1 , a keyway is provided on the right half roller 7 , and the shaft 1 and the right half roller 7 are fixedly connected via a key 2 .

[0022] In a preferred example, the shaft 1, the left half roller 6 and the right half roller 7 are coaxially arranged.

[0023] In a preferred example, mounting grooves are provided at both the front and rear ends of the left half roller 6 and the right half roller 7, and a slope with an inclined angle is provided on the side wall of the mounting groove close to the center of the roller, and the key roller tensioning plate 3 is a circular ring structure, and the inner side wall of the circular ring is a slope, and the slope of the mounting groove is arranged corresponding to the slope of the key roller tensioning plate 3.
