Description

Technical Field

[0001] This utility model belongs to the field of mechanical structures, and in particular relates to an automatic sorting device for highland barley seeds. Background Technology

[0002] Currently, during the barley breeding and harvesting process, the high impurity rate at the harvesting stage results in a large amount of impurities being mixed into the seeds. These impurities include not only weeds and other crop residues from the farmland, but also abiotic debris such as soil, which significantly impacts the seed purity in breeding work. Traditional barley harvesting typically relies on mechanical equipment for initial harvesting and cleaning, but existing harvesting equipment still has limitations in impurity removal and cannot achieve efficient impurity separation, thus leading to a high impurity rate. Utility Model Content

[0003] In view of this, the present invention aims to provide an automatic sorting device for barley seeds, so as to at least solve one of the problems in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] An automatic barley seed sorting device includes:

[0006] The sorting disc has a seed storage trough on one side and a sorting area on the other side. The outside of the seed storage trough is connected to a feeding chute, and the bottom of the feeding chute is connected to the inside of the seed storage trough.

[0007] The rotating upper plate is positioned above the sorting plate and rotates relative to it. The rotating upper plate is equipped with a suction nozzle, which is used to pick up material from the seed storage tank and send it to the sorting area.

[0008] Furthermore, including the bottom support plate, the sorting disc is mounted on the bottom support plate by a support rod, and the bottom support plate is provided with multiple reserved installation positions.

[0009] Furthermore, a support base is provided at the center of the sorting disc, and a rotating motor is installed on the support base. The power output end of the rotating motor is connected to the rotating upper disc.

[0010] Furthermore, the rotating upper plate includes two symmetrically arranged mounting areas. Negative pressure suction nozzles are installed in the mounting holes of the mounting areas via fixed brackets. Each suction nozzle is connected to the vacuum generator via a suction tube and a solenoid valve.

[0011] Furthermore, the seed storage trough includes a bottom plate, side plates, and an arc-shaped feed plate, which together form a trough-shaped structure with an opening at the top.

[0012] The side panel has a clearance notch to facilitate the passage of the suction nozzle;

[0013] The arc-shaped feeding plate is equipped with a strip-shaped feeding port. The bottom of the feeding chute is connected to the strip-shaped feeding port.

[0014] Furthermore, the bottom plate of the seed storage tank is inclined, and the horizontal plane of the side of the bottom plate closer to the air blowing structure is lower than the horizontal plane of the side farther away from the air blowing structure.

[0015] Furthermore, the bottom plate of the seed storage tank is provided with an arc-shaped mounting groove on the side near the arc-shaped feed plate, and an air blowing structure is provided in the arc-shaped mounting groove, with the air outlet at the top of the air blowing structure facing into the seed storage tank.

Detailed Implementation

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 5 As shown, this solution discloses an automatic sorting device for highland barley seeds. The overall workflow is as follows: the collected, packaged seeds containing impurities are poured into the top of the feeding chute 5. As the feeding chute 5 slides downwards, the seeds flow into the seed storage tank 4 through the strip-shaped feed inlet 431 at the bottom. The bottom plate 41 of the seed storage tank 4 has an arc-shaped mounting groove 411 at its edge. The top air outlet of the arc-shaped air blowing chamber 6 is installed in the arc-shaped mounting groove 411. The air inlet 61 at the bottom of the arc-shaped air blowing chamber 6 is connected to an external air source. The air outlet 62 of the arc-shaped air blowing chamber 6 is used to agitate the seeds. The material in the seed trough 4 is blown away to remove impurities such as barley husks or weeds, making it easier for the negative pressure suction nozzle 24 to pick up the barley seeds. After cleaning the impurities, blowing the barley seeds upwards makes it easier for the negative pressure suction nozzle 24 to pick up the seeds. In actual use, the installation height of the negative pressure suction nozzle 24 can be adjusted to ensure the success rate of the pick-up. In actual use, this device can be set up outdoors, and the blown impurities can be directly carried away by the wind. If used indoors, a dust collection structure or a baffle or curtain structure can be installed in the seed storage trough of this device to prevent dust from being stirred up.

[0032] After the negative pressure suction nozzle 24 picks up the barley seeds, the rotating motor 13 drives the rotating upper plate 2 to rotate 180° clockwise / counterclockwise to move the negative pressure suction nozzle 24 that picks up the barley seeds to the top of the sorting hole 7 on the sorting plate 1. Then the negative pressure suction nozzle 24 releases the barley seeds and they fall into the sorting hole 7 below, and flow into the seed collection box 72 through the sorting tube 71.

[0033] Meanwhile, the aforementioned vacuum suction assembly has two sets symmetrically arranged on the rotating upper plate 2. When one set of negative pressure suction nozzles 24 sucks up barley seeds, the other set is positioned above the sorting hole 7, just as the barley seeds are being placed down. This dual-set arrangement ensures that both sets of negative pressure suction nozzles 24 work simultaneously, improving efficiency. The negative pressure suction nozzles 24 and their control logic in this solution can be implemented using existing technology. For example, a solenoid valve acts as a control element, connected between the vacuum pump and the negative pressure suction nozzles 24, used to switch the vacuum on / off. When the solenoid valve is energized, the internal valve core actuates, opening the vacuum channel. The negative pressure generated by the vacuum pump is transmitted to the suction nozzle, allowing it to suck up the object. When the power is off, the valve core resets, cutting off the vacuum channel. Simultaneously, the negative pressure in the suction nozzle may be released through the vent, thus releasing the object.

[0034] Meanwhile, the negative pressure suction nozzle 24 of this solution can also be configured according to the characteristics of barley seeds: the suction needle port is selected with a miniature single-layer suction cup to ensure that no damage is caused when sucking up the seeds;

[0035] Meanwhile, when the two sets of negative pressure suction nozzles 24 are working in this solution, the rotating motor 13 drives the rotating upper plate 2 to rotate back and forth 180° clockwise and 180° counterclockwise, avoiding the airway entanglement caused by continuous clockwise or counterclockwise rotation.

[0036] In another embodiment, this solution uses a data acquisition device 8, which can be a camera, on the sorting disk 1. When the vacuum nozzle carries the barley seeds over the camera, the camera captures an image of the barley seeds. Existing image processing methods are used to classify the characteristics of the barley seeds, such as classifying them according to their size. At this time, each sorting hole 7 on the sorting disk 1 is used to collect one type of barley seed. The rotating upper disk 2 is rotated by the rotating motor 13, and the barley seeds on the negative pressure nozzle 24 are placed into the corresponding sorting hole 7. In this embodiment, the image recognition processing, the control logic of the rotating motor 13, and the suction / disconnection logic of the negative pressure nozzle 24 can all be achieved using existing technologies. This solution is only used to provide the structure used in the sorting process.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
