Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product processing machinery, and particularly relates to an intelligent sorting device for automatic arrangement of water chestnuts integrating a turntable and a multi-angle runner. Background Art

[0002] Water chestnuts are the fruits of the annual herbaceous aquatic plant Trapa bispinosa Roxb., containing rich starch, protein, glucose, unsaturated fatty acids and various vitamins. Water chestnuts have crispy skins and delicious flesh, and also have certain medicinal values. The varieties of water chestnuts are relatively easy to degenerate, which will affect sales and subsequent planting. To ensure the continuous optimization of water chestnut varieties, it is necessary to select and classify water chestnuts. The traditional method of seed selection and grading is mainly completed manually. The manual seed selection method has a large workload, low efficiency, high cost, and strong subjectivity without a unified standard, resulting in a high error rate. Therefore, the sorting method based on machine vision can effectively improve the accuracy of water chestnut seed selection. For water chestnuts with relatively complex shapes, the feeding link before machine vision image acquisition is the key problem studied in this invention.

[0003] In 2012, Cheng Fang et al. from Zhejiang University proposed a shrimp quality detection and grading device based on machine vision technology (authorization announcement number: CN 103056111 B). In the discharging module of this device, an oscillating feeder and a sensor are used. The oscillation speed of the oscillating feeder is gradually increased, thereby gradually reducing the number of shrimps, so as to achieve the effect that only a single shrimp is output under the camera each time. However, the oscillating feeder of this device controls the number of shrimps disorderly, and it is difficult to ensure that only a single shrimp is output each time, and it is difficult to ensure the accuracy of detection.

[0004] In 2021, Ma Qiucheng et al. from Xiangtan University proposed a shell lotus maturity detection device based on machine vision (application publication number: CN 114192425 A). The feeding mechanism of this device rolls the shell lotus through the feed hopper onto the inclined straight middle track, and rolls onto the two-side feeding conveyor belt area on the inclined plane. Each push block on the conveyor belt can hold one shell lotus, thereby realizing the single-piece output of shell lotus. However, this device has limitations and is only suitable for spherical crops such as shell lotus, and is not applicable to crops with relatively complex shapes such as water chestnuts.

[0005] In response to the problem of poor discharging effect in the above patents, in 2021, Liu Wei et al. from Northwest A&F University designed a post-harvest sorting production line for quasi-circular fruits (authorization announcement number: CN 216174338 B). This device uses a four-degree-of-freedom robotic arm to carry fruits, which can ensure the output of single fruits at equal time intervals. However, the robotic arm used in this device has a high cost and low efficiency, which is not conducive to the use of water chestnut batch production for seed selection and sorting.

[0006] In summary, in view of the problems of low efficiency, high cost, and poor accuracy in manual selection of water chestnuts, the present invention selects a sorting and seed selection method based on machine vision. To achieve the effect of collecting water chestnut images at equal time intervals by a camera and calculating and analyzing to send a classification signal to the sorting module, it is necessary to improve the discharging module. Therefore, how to adjust the water chestnuts from a piled state to a single regular output will be the key problem to be solved in the present invention. Summary of the Invention

[0010] As a further limitation of the present invention, the inner ring of the turntable is inclined downward at a certain angle in an umbrella shape, so that the water chestnuts entering the feeding bin move towards the edge of the turntable. Four convex dial plates are arranged on the outer ring of the turntable. The dial rod is installed on the inclined surface of the turntable. The dial rod is fixed in an arc shape and fits the inclined surface. Under the rotation of the turntable, the combined action of the dial rod and the dial plates at the edge of the turntable makes the water chestnuts move to the output port.

[0011] As a further limitation of the present invention, the anti-overlapping door mechanism adopts a V-shaped structure, including a slideway, a slider, a first anti-overlapping plate, a second anti-overlapping plate, a spring, and a pulley; one end of the first anti-overlapping plate is hinged to one end of the second anti-overlapping plate through a shaft, and a pulley is also installed on the shaft; the other end of the first anti-overlapping plate is fixed in the slideway by a slider, and the slideway is fixed on the output port of the rotary table feeding mechanism; the other end of the second anti-overlapping plate is hinged to the upper plate of the output port of the rotary table feeding mechanism, and the two hook rings of the spring are respectively fixed in the circular holes in the middle of the first anti-overlapping plate and the second anti-overlapping plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] As Figure 1The intelligent sorting device for automatic arrangement of the rhombus corners of an integrated turntable and multi-angle rotating wheel shown in the figure includes a turntable feeding mechanism 1, a multi-angle rotating wheel discharging mechanism 2, a detection mechanism 3, a sorting mechanism 4 and a workbench 5; the turntable feeding mechanism 1 and the multi-angle rotating wheel discharging mechanism 2 are placed on the workbench 5, the feeding channel of the multi-angle rotating wheel discharging mechanism 2 is aligned with the output port of the turntable feeding mechanism 1, and the discharging channel of the multi-angle rotating wheel discharging mechanism 2 is aligned with the front end of the conveyor belt of the detection mechanism 3; the sorting mechanism 4 is arranged at the end of the conveyor belt of the detection mechanism 3, and is used to receive the classification signal of the detection mechanism 3 and make corresponding sorting reactions to realize the classified collection of the rhombus corners.

[0028] As Figure 2 shown, the turntable feeding mechanism 1 includes: a feeding bin 11, a dial rod 12, a turntable 13, a guide wheel 14, a base 15, a large motor 16, a gear 17 and an anti-overlapping door mechanism 18; the feeding bin 11 is placed in a funnel shape on the base 15; a large motor 16 is arranged in the base 15, and a vertical shaft is arranged in the middle of the platform of the base 15. The turntable 13, the driven wheel in the gear 17 and the dial rod 12 are all sleeved on the vertical shaft; the turntable 13 is rotated by the large motor 16 driving the gear 17 to rotate, and eight guide wheels are placed at equal intervals on the platform of the base 15, and the guide wheels are in contact with the bottom edge of the turntable 13; to make the rotation of the turntable 13 more stable; the anti-overlapping door mechanism 18 is arranged at the initial position of the output port of the turntable feeding mechanism 1.

[0029] The inner ring of the turntable 13 is inclined downward at a certain angle in the shape of an umbrella, so that the rhombus corners entering the feeding bin 11 move towards the edge of the turntable 13. Four convex material-pushing plates 19 are arranged on the outer ring of the turntable 13. The dial rod 12 is installed on the inclined surface of the turntable 13. The dial rod 12 is fixed in an arc shape and fits the inclined surface. Under the rotation of the turntable 13, the combined action of the dial rod 12 and the material-pushing plate 19 at the edge of the turntable 13 makes the rhombus corners move to the output port; the output port is located on the side of the feeding bin 11, and the rhombus corners are output from this output port to the feeding channel 21 of the multi-angle rotating wheel mechanism 2.

[0030] As Figure 3As shown, the anti-overlapping door mechanism 18 adopts a V-shaped structure, including a slide 181, a slider 182, an anti-overlapping plate 183, an anti-overlapping plate 184, a spring 185, and a pulley 186; one end of the anti-overlapping plate 183 and one end of the anti-overlapping plate 184 are hinged to each other through an axis, and a pulley 186 is also installed on the axis; the other end of the anti-overlapping plate 183 is fixed in the slide 181 by a slider 182, and the slide 181 is fixed on the output port of the turntable feeding mechanism 1; the other end of the anti-overlapping plate 184 is hinged to the upper plate of the output port of the turntable feeding mechanism 1, and the two hooks of the spring 185 are respectively fixed in the circular holes between the anti-overlapping plate 183 and the anti-overlapping plate 184, so that the anti-overlapping door mechanism 18 increases the opening and closing angle when subjected to horizontal external force, and returns to the original angle through the spring 185 when the external force is lost or reduced. The pulley 186 is used to prevent the passing water chestnuts from getting stuck and avoid overlapping.

[0031] When the slider 182 moves to the two extremes of the slideway 181, the opening and closing angles of the two anti-overlapping plates reach a maximum and a minimum. When the opening and closing angle is the minimum, that is, the initial position, the distance between the lowest point of the pulley 186 and the surface of the turntable 13 is the average length of the short axis of the water chestnut; when the opening and closing angle is the maximum, the distance between the lowest point of the pulley 186 and the surface of the turntable 13 is less than the sum of the average distances of the two short axes. This distance setting allows the water chestnuts to be output in a single row without overlap when passing through the anti-overlapping door mechanism 18.

[0032] like Figure 4 As shown, the polygonal rotary wheel discharging mechanism 2 includes a feed channel 21, a rotary wheel body 22, a discharging channel 23, a small motor 24, a motor seat 25 and a polygonal rotary wheel 26; the feed channel 21 and the discharging channel 23 are respectively fixed on the rotary wheel body 22, the feed channel 21 is used to receive the water chestnuts output by the turntable feeding mechanism 1, and the discharging channel 23 is used to output a single water chestnut to the detection mechanism 3; the polygonal rotary wheel 26 is connected to the shaft of the small motor 24, and the shaft of the small motor 24 drives the polygonal rotary wheel 26 to rotate; the motor seat 25 is fixed to the tail of the small motor 24; the bottom of the motor seat 25 is inclined at a certain angle and fits with the workbench 5; the entire polygonal rotary wheel discharging mechanism 2 can be tilted to the lower left, that is, the water chestnuts enter the rotary wheel body 22 by gravity, and are discharged from the discharging channel 23 by gravity.

[0033] like Figure 5 As shown, the four sides of the polygonal wheel 26 are recessed inward to form arc grooves, the shape of which conforms to the outer structure of the water chestnut, and each arc groove and the inner cavity of the wheel body 22 form a spacing space that can only accommodate one water chestnut; Figure 6 As shown, a roller 261 is provided on each of the four corners of the polygonal rotating wheel 26, which is used to prevent the water chestnuts from getting stuck in the rotating wheel body 22, ensuring that there is only one water chestnut in each interval space. When the water chestnuts rotate to the lower outlet through the polygonal rotating wheel 26, they fall from the discharge channel 23 to the detection module 3 by gravity.

[0034] As Figure 7 shown, the detection mechanism includes a conveyor belt 31, a camera 32, and a drive motor 33; the camera 32 is fixed above the conveyor belt 31, and the drive motor 33 drives the conveyor belt 31 to rotate, transporting the water chestnuts through the conveyor belt 31 to below the camera 32; the camera 32 collects image information of a single water chestnut and transmits it to a computer, which classifies the water chestnuts according to characteristics such as their shape and color.

[0035] The sorting mechanism 4 includes a grading box 41, a sorting base 42, a sorting tray 44, a sorting belt 43, and a drive and control system; grading boxes 41 are placed on three sides of the sorting base 42, and each grading box 41 collects water chestnuts of different quality grades; a drive and control system is provided inside the sorting base 42, the sorting tray 44 is arranged above the sorting base 42 and in the middle of the sorting base 42, the sorting belt 43 is placed on the sorting tray 44, and the sorting belt 43 and the sorting tray 44 can rotate at multiple angles through the drive and control system; according to the classification signal sent by the detection mechanism 3, the drive and control system makes the sorting tray 44 rotate by a corresponding angle and the sorting belt 43 rotate counterclockwise to discharge the water chestnuts conveyed by the conveyor belt 31 forward, so that the water chestnuts move forward into the corresponding grading box 41, completing the intelligent sorting of the water chestnuts.

[0036] When the present invention works, first, pour the water chestnuts into the feeding bin 11, the turntable 13 starts to rotate, and the water chestnuts slowly slide down along the inclined surface of the turntable 13 to the edge of the turntable 13 by gravity. With the combined action of the dial rod 12 and the feeding plate 19, the water chestnuts are continuously sent to the output port of the feeding bin 11, and the water chestnuts pass through the anti-overlapping door mechanism 18 to achieve single-column non-overlapping output.

[0037] Second, the single-column water chestnuts output from the turntable feeding mechanism 1 enter the runner body 22 through the feeding channel 21. Driven by the small motor 24, the multi-angle runner 26 starts to rotate, ensuring that there is only one water chestnut in each arc-shaped groove. When it rotates to the lower outlet, the water chestnut slides down from the discharge channel 23 by its own gravity.

[0038] Third, the single water chestnut output from the multi-angle runner discharging mechanism 2 is conveyed on the conveyor belt 31 to below the camera 32. The camera 32 collects the image of the single water chestnut, and the computer calculates and classifies it according to its shape, color and other characteristics.

[0039] Fourth, the computer sends a sorting signal to the drive and control system of the sorting mechanism 4. The sorting tray 44 makes a corresponding sorting reaction and rotates by a corresponding angle. The water chestnuts are conveyed to the corresponding grading box 41 through the sorting belt 43, completing the intelligent sorting of the water chestnuts.

[0040] The intelligent sorting device for automatically arranging the rhombus corners of the integrated turntable and multi-angle rotating wheel provided by the present invention reflects its advantages of improving the efficiency of intelligent sorting of rhombus corners, reducing labor costs, improving the effectiveness and quality of the collected images, and enhancing the accuracy of rhombus sorting compared with the prior art. In the actual production process, by improving the height of the anti-overlapping door and the size and shape of the multi-angle rotating wheel groove, it can adapt to the discharging work before intelligent sorting of various crops, and has great market prospects and promotion value.

[0041] The present invention is not limited to the above embodiments. Based on the technical solutions disclosed in the present invention, those skilled in the art can make some substitutions and deformations of some technical features without creative labor according to the disclosed technical content, and these substitutions and deformations are all within the protection scope of the present invention.
