Abstract: Since the single coconut coir is difficult to meet the requirements of crop growth, it is necessary to mix organic manure with coconut coir fertilizer to solve the single fertilizer defect, resource waste and environmental pollution problems.This paper focus on the current market solid mixing equipment does not mix uniformly or the power is inconsistent, and the mixing machine of coconut coir with organic manure cannot be used directly at present, the coconut coir organic fertilizer mixing machine is designed.In this paper, the main structure of the machine have been designed and analysed, using ANSYS software for finite element analysis. The test results show that the mixing uniformity of this machine is 83.46% in 10 minutes, which can meet the mixing requirements of coconut coir and livestock manure organic fertilizer.
