Description

A kind of macadamia nut screening device

technical field

The utility model belongs to the technical field of fruit screening devices, in particular to the field of screening devices suitable for macadamia nuts.

Background technique

Existing sorting devices for macadamia nuts are generally horizontal sieve bed sorters or drum sorters.

The disadvantage of the horizontal sieve bed sorter is that it occupies a large area and the classification efficiency is low, only 2-3 grades. If the classification grade is increased according to actual needs, more classification tanks will be expanded, which will increase the equipment. area, thereby greatly increasing the cost.

The disadvantages of the drum sorting machine are that the equipment is large, the cost is high, the noise is loud, and the number of classifications is only 2. Since the entire drum needs to be rolled to sort the shells, its energy consumption is also large.

The fruit-pulling rakes of the fruit-distributing tray of the present utility model are all connected on the same central axis.

On the one hand, the base of the central axis plays the role of fixing the central axis and the fruit rake; The setting of the shaft base can prevent the root of the fruit rake from being poor in fruit-pulling effect and cause nuts to accumulate at the root of the fruit rake. The motor drives the central shaft and the central shaft base to move, and then drives the fruit rake installed on the central shaft and the central shaft base to perform fruit screening.

The rake teeth are hook-shaped and penetrate 10-15mm into the pores of the sieve channel. When the nuts are embedded in the sieve channel too tightly during the fruit picking process, the curved rake teeth that extend downward will lift the nuts during the movement. Fruit jams will occur.

The beneficial effects of the utility model are:

(1) The grading efficiency is greatly improved, and the grading frame can be set according to the needs, and the nut grades above 4 grades can be separated in one sorting;

(2) The energy consumption is reduced, and there is no need to drive the heavy drum, only need to start the motor, so that the central axis drives the fruit rake to rotate to complete the grading work;

(3) Manufacturing cost and use cost are greatly reduced.
