Abstract
The invention discloses a multipoint hardness signal generating device for fruits. The device comprises a vertical rack, wherein a hardness signal generating platform, a transmission mechanism and a driving mechanism are respectively arranged in the vertical axial direction of the rack from top to bottom. The mechanical transmission mechanism is adopted to realize that multiple pressing heads are pressed into fruits to be detected at the same time and at the same speed, and hardness signals are converted into electrical signals through piezoelectric sensors on the pressing heads, and the electrical signals are output. Pressing needles with appropriate sizes are selected according to the types of fruits, and hardness signal generating of multiple parts of different types of fruits can be completed.
Description
Technical field
The invention belongs to fruit and vegetable manufacture field, relate generally to a kind of fruit multiple spot hardness signal generation apparatus.
Background technology
Hardness is to evaluate the important physical index of fruit maturity, freshness and inside quality, rear transportation, storage, deep processing etc. are determined, adopted to the fruit picking phase and have appreciable impact.It is the major way of current fruit hardness measurement that application fruit hardness meter is measured fruit hardness, when fruit hardness meter is measured, for most fruit such as pears, apple, "Hami" melons, need to remove the peel processing, can only carry out single-point hardness measurement to fruit at every turn, measure efficiency lower, and the factors such as the verticality of peeling thickness, pressing press-in speed, pressing and data read are generally difficult to be consistent, and cause measuring error larger.And for same fruit, also there is some difference in different growth periods for different parts hardness, this difference has important indicative function for some feature of judging fruit.Utilize mechanical type to be pressed into mechanism and replace personnel manual operations, utilize piezoelectric sensor that hardness signal is changed into electric signal output, not only can improve and measure efficiency and measuring accuracy, be equipped with applicable control system simultaneously and can also realize the automatic processing of measurement result.Development fruit multiple spot hardness signal generation apparatus is the basis of development fruit multiple spot hardness automatic checkout equipment, has important theoretical and practical significance.
Summary of the invention
The object of this invention is to provide a kind of fruit multiple spot hardness signal generation apparatus, improve efficiency and the precision of fruit hardness measurement, there is simple and reliable for structure, easy operating.
In order to achieve the above object, the technical solution used in the present invention is: a kind of fruit multiple spot hardness signal generation apparatus, comprises and the frame of vertical layout along frame vertical axis direction from top to bottom, be divided into hardness signal generating mechanism, gear train and driving mechanism.The hardness signal generating mechanism being arranged in detection platform is comprised of multiple pressure heads with pressing and piezoelectric sensor and objective table, multiple pressure heads in the track of platform, can send multiple spot hardness electric signal according to circumferential directions according to the feature that is placed on fruit to be measured on objective table simultaneously; Gear train is comprised of fork identical with pressure head number, loaded ring and drive screw, can realize multiple pressure heads simultaneously, be synchronizedly pressed into fruit to be measured; Driving mechanism is a monolithic processor controlled stepper motor, can be measuring mechanism power is provided.
The beneficial effect that the present invention has is: adopt mechanical transmission mechanism and piezoelectric sensor to produce fruit multiple spot hardness signal, be convenient to realize the automatic measurement of fruit hardness, solve fruit hardness measurement efficiency low, the technical barrier of low precision.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention; Fig. 2 is three-dimensional entity model of the present invention.In figure: 1, pressure head, 2, fork, 3, frame, 4, drive screw, 5, stepper motor, 6, Transmission Room base plate, 7, Transmission Room shell, 8, loaded ring, 9, objective table, 10, hardness signal generation platform.
Embodiment
Take fruit six point hardness signal generation apparatus as example, by reference to the accompanying drawings embodiment of the present invention is described in detail below.
Before measuring, instrument is prepared: according to the kind of fruit to be measured, select the pressing of suitable dimension, by being installed on pressure head 1 of pressing.Adjust and measure diameter, coincide with fruit size to be measured.Measure operation: fruit to be measured is placed on objective table 9, regulates the height of objective table with respect to hardness signal generation platform 10, make fruit position to be measured and pressure head 1 in same plane.Start stepper motor, measure moment of torsion and reach pressure head 1 by drive screw 4, loaded ring 8, fork 2, pressing is pressed into distance certain in fruit with certain speed, by piezoelectric sensor, fruit hardness signal is externally exported with electric signal.
