Yuchai heavy industry two invention patents won the fifth Guangxi Invention Exhibition Fair Project Gold Award

December 15, the fifth Guangxi invention creation achievements exhibition trading will winners announced, Yuchai heavy industry priority valve of hydraulic excavator and "a shift hydraulic excavator tree device" patent of invention with high patent quality and good social and economic benefits, won the gold medal and the silver award.
"Hydraulic excavator priority valve", through the installation of priority valve, hydraulic excavator boom to achieve the need to give priority to rotation. Priority valve is suitable for many kinds of hydraulic system, which has the advantages of simple structure, low cost, stable performance, long service life, wide application and so on. The priority valve broke the international hydraulic parts factory technical barriers, improve the performance level of Yuchai excavator, enhance the market competitiveness of products.
"A shift hydraulic excavator device tree" the four connecting rod mechanism simulating hand hold trees, with on long span under the baffle support and hydraulic power hold, to achieve the safety of large trees stability control. Four connecting rod mechanism can be realized according to the size of different trees to shovel the appropriate soil diameter, can replace the human digging trees, but also can replace the crane loading and unloading trees. The action of the hydraulic oil cylinder driving slide shovel to simulate the human shovel is very powerful and reliable. The device can efficiently and quickly realize the excavator to remove and grow trees, in order to machine instead of manual work, improve the work efficiency, reduce the cost.
As the current domestic hydraulic excavator product spectrum manufacturers the most complete, Yuchai heavy industry is accelerating its own development at the same time, always adhere to the independent innovation, the company has developed a variety of new products with independent intellectual property rights, has received 6 invention patents, passed the second batch of the autonomous region of IPR advantageous enterprises cultivate unit identified, undertaken and completed the patent of the autonomous region science and technology projects, and repeatedly won the "Yulin City, an application for a patent for invention is advanced unit" title, company technology strength row in the forefront of the industry.
