detailed description

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings and examples.

A twin-shaft paddle mixer for the preparation of organic fertilizers, comprising a mixing bin 14, a driving device, a transmission mechanism, a main shaft I10, a main shaft II11, a bacteria liquid spraying device 7, a water adding device and a PLC controller.

The driving device includes a motor 2, the motor 2 is a variable frequency motor, the output shaft of the motor 2 is connected with the reducer 4 through an elastic pin coupling 3, and the transmission mechanism is a gearbox 6 filled with lubricating oil with two gears inside. The gearbox 6 is connected to the output end of the reducer 4 through the slider coupling 5, and the gearbox 6 is connected to the main shaft I and the main shaft II at the same time. This structure is lubricated by lubricating oil splashing, which solves the problem that the lubricating grease is melted and thrown out, the lubricating effect is reduced, and it is easy to absorb dust, which causes the defects of gear wear.

The main shaft I10 and the main shaft II11 are rotatably supported on the mixing bin 14, the two ends of the main shaft I10 and the main shaft II11 are fixed on the two ends of the mixing bin 14 through the bearing housing 13 with self-aligning ball bearings, the axes of the main shaft I10 and the main shaft II11 They are parallel to each other, the rotational speeds of the main shaft I10 and the main shaft II11 are the same, the rotation directions of the main shaft I10 and the main shaft II11 are opposite, and the outer surfaces of the main shaft I10 and the main shaft II11 are helical. On the contrary, the paddle 8 is detachably connected to the paddle mounting plate 9 by bolts, and the paddle 8 in this embodiment has a fan-shaped structure.
