8. The straw-based pet cat litter preparation device according to claim 7, characterized in that: The refinement processing mechanism comprises: An anti-clogging auger, the anti-clogging auger is arranged in the crushing processing seat; A straw guide seat fixedly connected to the anti-clogging auger, the straw guide seat is used to guide the crushed straw raw material; The fine crushing part is arranged at the bottom of the crushing processing seat, the fine crushing part is connected with the straw guide seat, the fine crushing part is driven by the fine linkage part, and the pre-treated straw raw material is finely crushed.

9. The straw-based pet cat litter preparation device according to claim 8, characterized in that: The refinement and crushing section comprises: At least one set of arc-shaped linkage arms, one end of which is fixedly connected to the gear linkage ring, and the other end of which passes through the thinning roller support seat and is fixedly connected to the straw guide seat; At least one group of fine crushing rollers, the fine crushing rollers are rotatably mounted on the fine crushing roller support seat, and the outer wall of the fine crushing roller is circumferentially provided with multiple groups of fine teeth; The positioning crushing roller is arranged in the thinning roller support seat, the positioning crushing roller is fixedly connected to the gear positioning shaft, a plurality of groups of crushing teeth are arranged circumferentially on the side wall of the positioning crushing roller, and the crushing teeth are meshed with the thinning teeth for transmission.

10. A method for preparing straw-based pet cat litter, implemented by using the straw-based pet cat litter preparation device according to any one of claims 1 to 9, characterized in that: The method for preparing the straw-based pet cat litter specifically comprises: Step S10, when working, the straw raw material is put into the feeding trough, and then the pre-driving motor is turned on. The pre-driving motor is started to drive the first gear and the second gear to rotate, so that the first gear drives the first crushing roller and the first crushing tooth to pre-crush the straw raw material in the crushing trough, and the second gear drives the second crushing roller and the second crushing tooth to pre-crush the straw raw material in the crushing trough. At the same time, when the first crushing roller and the second crushing roller rotate, they contact the auxiliary roller pressure ring, thereby driving the auxiliary roller pressure ring to rotate, so that the auxiliary roller pressure ring brings the straw raw material into the crushing trough and performs roller crushing on the raw material; Step S20, the rotation of the second gear can drive the driving cam to rotate, so that the driving cam intermittently squeezes the squeezing ball, so that the squeezing ball drives the adjusting linkage rod to swing, the adjusting linkage rod drives the fan gear to swing, the fan gear drives the first rack to move, the first rack drives the adjusting push rod and the second rack to move, and then the second rack drives the third gear and the roller bearing shaft to rotate, the roller bearing shaft drives the roller bearing seat and the bearing rolling seat to swing, further realizing the adjustment of the rolling range of the auxiliary roller pressing ring, and further realizing the roller crushing process of the raw material; Step S30, when the pre-treated straw raw material falls into the crushing processing seat, the thinning motor is turned on, and the thinning motor can drive the fourth gear, the fifth gear and the gear linkage ring to rotate, and the rotation of the gear linkage ring can drive the arc linkage arm and the thinning roller supporting seat to rotate, so that the arc linkage arm drives the straw guide seat and the anti-clogging auger to rotate, so that the anti-clogging auger brings the straw raw material into the bottom of the crushing processing seat; Step S40, the rotation of the refining roller support seat can drive the refining crushing roller and the refining teeth to rotate relative to the positioning crushing roller and the crushing teeth. The meshing of the refining teeth and the crushing teeth can further roll and crush the pretreated straw raw material, thereby providing roller pressures of multiple angles and directions for the raw material refining rolling. The refined and crushed straw raw material is discharged through a discharge pipe, and then the straw raw material is subjected to high-temperature carbonization, granulation and drying and curing treatments in sequence to obtain straw-based pet cat litter.
