The utility model relates to the technical field of plastic raw material processing, concretely to a multi-station plastic raw material receiving equipment, including base, set up on the receiving tank of base, the screen pipe of one end is inserted into receiving tank, set up on the feed pipe of receiving tank top, the angle adjusting mechanism that is used for adjusting the feed direction of feed pipe, the bottom end of feed pipe is linked together screen pipe, a plurality of screen holes that communicate receiving tank inside are radially set up on screen pipe, set up spiral feeding mechanism in screen pipe, set up discharge port after screen pipe stretches out receiving tank, the utility model can be suitable for the plastic raw material forming equipment use of inclined discharge port and vertical discharge port, and the applicability is better, can also automatically screen out the crushed material, the powder, etc.

A roller reamer for oilfield drilling, relating to the field of oilfield drilling tools, includes a connecting body, a roller shaft, a roller, a shaft seat, a connecting bolt, a connecting disc, and a locking sleeve. Two shaft seats are respectively connected and installed in slots opened on the connecting body using connecting bolts. The roller shaft is connected between the shaft seats, and the roller is fitted on the roller shaft. The head of the connecting bolt has a transverse groove. The connecting disc and the locking sleeve are sequentially installed in the bolt connection hole. An upper key pin and a lower key pin are respectively provided on the upper and lower end faces of the connecting disc. The lower key pin corresponds to and fits into the transverse groove. The inner circumferential surface of the locking sleeve has a reverse thread, and the bottom end has a limiting groove that corresponds to and fits into the upper key pin. A strip-shaped sawtooth ridge is provided in the bolt connection hole. The locking sleeve is interference-fitted and impact-embedded into the bolt connection hole, establishing a sawtooth meshing fit with the shaft seat. This can limit and constrain the connecting bolt in the axial direction and also rotate and constrain the connecting bolt in the circumferential direction, strengthening the locking effect on the connecting bolt and improving the locking effect.

This invention belongs to the field of vehicle suspension technology, specifically relating to a vehicle suspension system and assembly method suitable for solid axles. The invention includes a fixing device symmetrically installed at clamping positions at both ends of a solid axle; the fixing device is equipped with a frame connection device for connecting to the vehicle frame and a support assembly for supporting the vehicle frame; the fixing device includes an upper connector, a lower connector, a front connector, and a rear connector; when the fixing device is installed on the solid axle, the upper and lower connectors, and the front and rear connectors, are connected by adjusting rods. The fixing device of this invention, with its adjustable width and height via adjusting rods, solves the problem in the prior art where each axle needs to be matched to a specific vehicle suspension system and requires customized modification of the axle, effectively saving assembly time, improving assembly efficiency, and ensuring the installation stability of the axle and suspension system.
