Corn seed quality detection device

Abstract

The present invention relates to the technical field of detection devices, and discloses a corn seed quality detection device, comprising a base, a rotating drum rotatably mounted in the middle of the top of the base, a limiting block with an arc-shaped structure and a positioning block with an annular structure provided around the rotating drum, and a first bevel rack with an arc-shaped structure fixedly mounted on the top of the positioning block. The present invention provides multiple sampling mechanisms. As the rotating drum rotates, when the sampling mechanism reaches the starting delivery area, the corresponding electromagnetic valve is opened, and then the corn seeds are evenly delivered into the feed tray body through a gradually shrinking telescopic tube. The first photo is taken in the first detection area by an infrared spectrum camera, and then the rotating drum continues to rotate and reaches the second detection area. The feed tray body completes a 180-degree rotation, thereby making the other side of the sampled corn seeds face the infrared spectrum camera, thereby improving the comprehensiveness of the equipment's surface detection of corn seeds and achieving higher detection accuracy.

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a corn seed quality detection device. Background Art

[0002] The corn seed quality testing device is a professional equipment used to evaluate the quality of corn seeds. It ensures that the seeds meet the sowing or storage standards by analyzing indicators such as the seeds' physical properties (such as size, color, integrity), physiological activity (such as germination rate, vitality) and composition (such as water content, nutrients, and pest and disease infection). Seeds are the foundation of agricultural production, and high-quality corn seeds directly determine the germination rate, stress resistance, and final yield.

[0003] In the prior art, a conveyor belt is often used to carry seeds through an infrared camera for detection. However, the back of the seeds becomes a blind spot for detection, and some unqualified seeds are often missed and not detected, resulting in low detection accuracy. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a corn seed quality detection device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] As a further solution of the present invention, two cavities are opened on both sides of the material tray bracket, and an electric telescopic rod and a battery are fixedly installed in each of the cavities. The telescopic ends of the two electric telescopic rods are fixedly installed on one side of the cover plate, and a first helical gear ring is fixedly sleeved on the surface of the material tray body. A driven bevel gear meshing with the first helical gear ring is rotatably installed on one side of the material tray bracket.

[0009] As a further solution of the present invention, the sampling mechanism also includes a material receiving funnel and a connecting rod. The material receiving funnel is fixedly installed on the surface of the main shaft. The surface of the main shaft is provided with a sliding groove that is compatible with the connecting rod. A reciprocating screw is rotatably installed in the sliding groove. One end of the connecting rod is slidably installed in the sliding groove and is threadedly connected to the reciprocating screw. An elbow is fixedly installed on the other end of the connecting rod. A telescopic tube is connected between the elbow and the bottom end of the material receiving funnel.

[0010] As a further solution of the present invention, one end of the reciprocating screw passes through the material tray bracket and is fixedly installed on the rotation center of one side of the driven bevel gear, and the other end of the reciprocating screw passes through the main shaft and the outer surface of the rotating drum and is fixedly installed with a driving bevel gear at the end, and the driving bevel gear is intermittently engaged with the second helical rack.

[0011] As a further solution of the present invention, a seed collecting and distributing cylinder is fixedly installed on the top of the rotating drum, and a drainage block with a conical structure is provided at the bottom of the seed collecting and distributing cylinder. A plurality of discharge ports are evenly arranged on the circumference of the bottom of the seed collecting and distributing cylinder, and an electromagnetic valve is fixedly installed in each of the discharge ports. The bottom outlet of each electromagnetic valve is connected to a curved pipe that drains to the top of the material receiving funnel, and a plurality of through holes are provided on the surface of the rotating drum for avoiding the electromagnetic valves.

[0012] As a further solution of the present invention, a side bracket is fixedly installed on one side of the top of the base, an infrared spectrum camera is fixedly installed on the top of the side bracket, the shooting end of the infrared spectrum camera passes through the side bracket toward the base, and a feeding funnel for collecting seeds is fixedly installed on one side of the top of the base.

[0013] As a further solution of the present invention, a driven pulley is fixedly embedded on the surface of the rotating drum, a servo motor is fixedly installed on one side of the top of the base, a driving pulley is fixedly installed on the output end of the servo motor, and a synchronous belt is connected between the driving pulley and the driven pulley.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting up multiple sampling mechanisms, as the drum rotates, when the sampling mechanism reaches the starting delivery area, the corresponding electromagnetic valve is opened, and then the corn seeds are evenly delivered into the feed tray body through the gradually shrinking telescopic tube. The sampling mechanism reaches the first detection area, and the transparent cover plate covers the top of the feed tray body under the drive of the electric telescopic rod and completes the first photo through the infrared spectrum camera.

The feed tray body completes a 180-degree rotation, so that the other side of the sampled corn seeds faces the infrared spectrum camera, thereby improving the comprehensiveness of the equipment's detection of the corn seed surface and improving the accuracy of the detection;

[0016] 2. The rotation of the drum drives the active bevel gear in the sampling mechanism that is receiving the material to engage with the second helical rack and rotate, which in turn drives the reciprocating screw to rotate. The reciprocating screw drives the connecting rod to move toward the drum, thereby contracting the telescopic tube. At the same time, the reciprocating screw drives the driven bevel gear to rotate, and the driven bevel gear drives the first helical gear ring to rotate, thereby driving the feed tray body to rotate, so that the corn seeds are distributed in a spiral line in the feed tray body, avoiding the accumulation of corn seeds and improving the accuracy of the equipment in capturing unqualified corn seeds.

[0030] During use, by setting up multiple sampling mechanisms 6, as the drum 4 rotates, when the sampling mechanism 6 reaches the starting delivery area 17, the corresponding electromagnetic valve 502 is opened, and then the corn seeds are evenly delivered into the tray body 603 through the gradually shrinking telescopic tube 614. The sampling mechanism 6 reaches the first detection area 18, and the transparent cover 611 covers the top of the tray body 603 under the drive of the electric telescopic rod 610 and completes the first photo shooting through the infrared spectrum camera 8. Then the drum 4 continues to rotate, and as the second bevel gear ring 606 on the surface of the main shaft 605 engages and rotates with the first bevel rack 10, the sampling mechanism 6 is driven to flip over as a whole until it reaches the second detection area 19. The tray body 603 completes a one hundred and eighty degree rotation, so that the other side of the sampled corn seeds faces the infrared spectrum camera 8, thereby improving the comprehensiveness of the equipment's surface detection of corn seeds and improving the accuracy of the detection.

[0031] In this embodiment, the sampling mechanism 6 also includes a material receiving funnel 615 and a connecting rod 612. The material receiving funnel 615 is fixedly installed on the surface of the main shaft 605. The surface of the main shaft 605 is provided with a slide groove 618 that is compatible with the connecting rod 612. A reciprocating screw rod 608 is rotatably installed in the slide groove 618. One end of the connecting rod 612 is slidably installed in the slide groove 618 and is threadedly connected to the reciprocating screw rod 608. The other end of the connecting rod 612 is fixedly installed with an elbow 613. A telescopic tube 614 is connected between the elbow 613 and the bottom end of the material receiving funnel 615. One end of the reciprocating screw rod 608 passes through the material tray bracket 601 and is fixedly installed with the rotation center of one side of the driven bevel gear 607. The other end of the reciprocating screw rod 608 passes through the main shaft 605 and the outer surface of the rotating drum 4 and is fixedly installed with a driving bevel gear 609 at the end. The driving bevel gear 609 is intermittently engaged with the second helical rack 16.

[0032] During use, the rotation of the rotating drum 4 drives the active bevel gear 609 in the sampling mechanism 6 that is receiving the material to engage with the second helical rack 16 and rotate, thereby driving the reciprocating screw rod 608 to rotate, and the reciprocating screw rod 608 drives the connecting rod 612 to move toward the rotating drum 4, thereby causing the telescopic tube 614 to contract. At the same time, the reciprocating screw rod 608 drives the driven bevel gear 607 to rotate, and the driven bevel gear 607 drives the first helical gear ring 604 to rotate, thereby driving the feed tray body 603 to rotate, thereby causing the corn seeds to be distributed in a spiral line in the feed tray body 603, thereby avoiding the accumulation of corn seeds and improving the accuracy of the equipment in capturing unqualified corn seeds.

[0033] In this embodiment, a seed collecting and distributing cylinder 5 is fixedly installed on the top of the rotating drum 4, and a drainage block 501 with a conical structure is provided at the bottom of the seed collecting and distributing cylinder 5. A plurality of discharge ports are evenly opened on the circumference of the bottom of the seed collecting and distributing cylinder 5, and an electromagnetic valve 502 is fixedly installed in each discharge port. The bottom outlet of each electromagnetic valve 502 is connected to a curved pipe that drains to the top of the receiving funnel 615. A plurality of through holes for avoiding the electromagnetic valve 502 are opened on the surface of the rotating drum 4, a side bracket 7 is fixedly installed on one side of the top of the base 1, an infrared spectrum camera 8 is fixedly installed on the top of the side bracket 7, and the shooting end of the infrared spectrum camera 8 passes through the side bracket 7 toward the base 1, and a discharge funnel 9 for collecting seeds is fixedly installed on one side of the top of the base 1, a driven pulley 11 is fixedly embedded on the surface of the rotating drum 4, a servo motor 14 is fixedly installed on one side of the top of the base 1, a driving pulley 13 is fixedly installed on the output end of the servo motor 14, and a synchronous belt 12 is sleeved between the driving pulley 13 and the driven pulley 11.

[0034] When in use, the servo motor 14 drives the rotating drum 4 to rotate through the driving pulley 13, the driven pulley 11 and the synchronous belt 12, and then the multiple sampling mechanisms 6 perform sampling, detection and discharge in sequence, so that the detection process can be carried out continuously, thereby improving the detection efficiency of the equipment.

[0035] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: by setting the functional areas on the top of the base 1 as the starting delivery area 17, the first detection area 18, the second detection area 19, the unloading area 20, the tray reset area 21 and the telescopic tube starting reset area 22, as the drum 4 rotates, when the sampling mechanism 6 reaches the starting delivery area 17, the corresponding electromagnetic valve 502 is opened, and then the corn seeds are evenly dropped into the tray body 603 through the gradually contracting telescopic tube 614, and the sampling mechanism 6 reaches the first detection area 18, Driven by the electric telescopic rod 610, the transparent cover 611 covers the top of the feed tray body 603 and completes the first photo shooting through the infrared spectrum camera 8. Then the drum 4 continues to rotate, and as the second bevel gear ring 606 on the surface of the main shaft 605 engages and rotates with the first bevel rack 10, the sampling mechanism 6 is turned over as a whole until it reaches the second detection area 19. The feed tray body 603 completes a 180-degree rotation, so that the other side of the sampled corn seeds faces the infrared spectrum camera 8, thereby improving the comprehensiveness of the equipment's detection of the corn seed surface and improving the accuracy of the detection;

[0036] Then the drum 4 continues to rotate, and the second bevel gear ring 606 in the sampling mechanism 6 continues to mesh and rotate with the first bevel rack 10 until the tray body 603 is open and facing upward. At this time, the sampling mechanism 6 is in the tray reset area 21. Thereafter, the main shaft 605 is slidably connected with the limit block 3 through the limit groove 617, so that the tray body 603 remains stable. When the sampling mechanism 6 reaches the telescopic tube start reset area 22, the active bevel gear 609 begins to mesh with the second bevel rack 16, and then the reciprocating screw rod 608 begins to rotate, driving the connecting rod 612 to move until the elbow 613 is brought to the top of the center of the tray body 603. At this time, the sampling mechanism 6 once again reaches the start delivery area 17. Through the arrangement of multiple sampling mechanisms 6, the device can continuously perform sampling, detection and discharge with high detection accuracy.
