Abstract

Abstract: A tree trunk injector with large pressure and high capacity was successfully developed. The new machine has the advantages of high pressure and high volume injection without backflow of the injected liquid. It realized quick injection of large volume of nutrition solutions. New type of injecting pinhead was also produced on the base of studying the liquid transmitting mechanism from pinhead to tree trunk. It solved the leakage problem of tree trunk injection. The sealing function was realized on the results to study the living wood mechanics. The ringshaped drill edge could directly make a hole and easy get rid of the wood it cut in its hole. It saved money on expansive drilling equipment for the users. With the assistance of computer the moving rule of power application devices was designed and analyzed. The application result in the field test showed the injector was very effective.
