The invention relates to a primary coconut pulp juice obtaining machine and a control method thereof. The obtaining machine is characterized in that the whole machine comprises a storage hopper, a feeding chain plate type conveyor, a feeding conveyor power rack, a partition plate guide type discharging hopper, an upper pulp-taking rack, a lower pulp-taking rack, a pulp-taking chain plate type horizontal conveyor, an air hole opening mechanism, a coconut meat scraping mechanism, a pulp discharging hole opening mechanism, an air-pressure accelerated pulp discharging mechanism, a primary pulp andjuice collection pot, a PLC logic control circuit and a control air circuit. Two or more longitudinal vertical guide partition plates, including two side plates of the discharging hopper, are arranged in the partition plate guide type discharging hopper in the width direction, and an guide groove supporting plate is positioned at the lower ends of the opposite faces of every two guide partition plates, wherein the section of the guide groove supporting plate is in an arc shape, and the guide groove supporting plate slants downwards. Compared with the prior art, the primary coconut pulp juiceobtaining machine has the advantages of being simple in production, low in labor consumption, high in production efficiency, high in degree of automation, sanitary and low in cost.
