Abstract

The utility model relates to a rotary fruit grading device for sorting and outputting the fruits according to the instructions. The rotary fruit grading device comprises a stepper motor (1), the output shaft of the stepper motor (1) is fixedly connected with a rotary positioning grading cylinder (2) with a fruit feeding opening and a fruit discharging opening, and an acute angle is formed between the axial line of the rotary positioning grading cylinder (2) and the output shaft of the stepper motor (1). The rotary fruit grading device has the advantages that the structure is simple, the rotary fruit grading device is reliable and durable, and the fruits can be accurately positioned at the corresponding grading port before fed into the cylinder, thereby the fruits can be accurately and continuously output and accurately sorted by grade.

Description

Rotary fruit grading plant

Technical field

The utility model relates to a kind of according to the rotary fruit grading plant of instruction with fruit classification output.

Background technology

At present, some automaticities are used in practice more widely than higher fruit classifier, its classification principle is the grade discrimination zone of fruit being arranged the fruit that is conveyed into grader in order by suitable mechanical moving device, weight, size, color with fruit are foundation, utilize the optical characteristics detection of fruit to determine grade, afterwards grade discrimination information is sent into intelligence control circuit or CPU and handled and send control signal at any time, the classification actuating unit of being carried out terminal by control carries out classification.

But the design of classification actuating unit is a difficult point, and existing fruit classification actuating unit often can not accurately be positioned each classification mouth place, causes the graded category blending, does not reach the purpose of accurate classification.

The utility model content

The purpose of this utility model provides a kind of rotary fruit grading plant, and this grading plant can be positioned the classification mouth of current fruit correspondence exactly according to control signal, and it is simple in structure, reliability and durability.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of rotary fruit grading plant, its special feature is, comprise stepper motor, the rotation bearing classification tube that the output shaft of this stepper motor and has a fruit entrance and exit is fixedlyed connected, and is acute angle between the axis of this rotation bearing classification tube and the output shaft of stepper motor.

Wherein rotate between the output shaft of the axis of bearing classification tube and stepper motor and be 30-60 degree angle.

The beneficial effects of the utility model are, and are simple in structure, reliability and durability, behind controlled signal, can be positioned corresponding classification mouth exactly before fruit is gone into tube, thereby the accurate output fruit of realizing is pressed grade separation.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

The specific embodiment

Come the utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, the fruit that detects through grade by conveyer belt orderly be transported to terminal point, fruit whereabouts side is facing to the inlet of rotation bearing classification tube 2, stepper motor 1 is controlled the corner of output shaft by the corresponding umber of pulse that receives, rotate and make outlet be positioned the corresponding classification mouth 3 in below in advance thereby drive rotation bearing classification tube 2, and the position of the relative conveyer belt of inlet of rotation bearing classification tube 2 is constant all the time during work.

The velocity of rotation of rotation bearing classification tube 2 is set continuously according to the quantity and the fruit of classification mouth 3 blanking time of output, and velocity of rotation can reach the purpose of accurate location and the accurate classification of fruit greater than the continuous output speed of fruit.

Claims

1, a kind of rotary fruit grading plant, it is characterized in that: comprise stepper motor (1), the rotation bearing classification tube (2) that the output shaft and of this stepper motor (1) has a fruit entrance and exit is fixedlyed connected, and is acute angle between the output shaft of the axis of this rotation bearing classification tube (2) and stepper motor (1).

2, rotary fruit grading plant as claimed in claim 1 is characterized in that: wherein rotate between the output shaft of the axis of bearing classification tube (2) and stepper motor (1) and be 30-60 degree angle.
