A few days ago, the patent of "Locking the square groove of the check valve nut of a hydraulic excavator" issued by Guangxi Yuchai Engineering Co., Ltd. has successfully passed the examination of the State Intellectual Property Office and was granted a utility model patent.
“Hydraulic Excavator Check Valve Nut Locking Groove†is a new structure developed by Tan Jun, technical staff of Yuchai Engineering Machinery Research Institute. The advantage of this structure is that the nut can be locked without drilling, the positioning structure can be directly machined on the part, and can be directly locked to greatly increase the production efficiency; no damage to the screw thread ensures the performance of screw fastening; the pin is relatively easy to disassemble and the nut is disassembled. , The screw can be re-assembled and used, there is no problem that the nut produced under the locking method can not be reused after being disassembled, which can greatly save the cost.

Heat generated by the hot air into the wood chip dryer cylinder, the cylinder body wall first, leaf axis or feed plate metal preheating, sawdust from sawdust dryer feed into the mouth, inside the wood chip dryer materials the blade shaft or feed plate raise or the rotation of the drum itself float in the sky, and then material, blade shaft and cylinder or feed plate and other metal intimate contact, using hot air separation of moisture away dry material.The material is discharged from the sawdust dryer outlet or from the bottom of the configured shakron, and the hot and humid gas and smoke are removed from the top of the shakron.The material mainly depends on the center of the blade shaft or the uplift role of the plate, or the sawdust dryer has a tendency to Angle of operation.
