[0002] When conducting breeding research on different pear varieties, a pear variety identifier is needed to identify them in order to select different pear varieties for breeding research. A pear variety identifier is a device used to identify different pear varieties. By integrating image recognition technology, it can quickly and accurately identify different varieties of pears, helping growers and managers to better manage and classify pear trees. However, existing pear identification devices require testing each pear individually and placing it into the corresponding collection box after testing. Each step in this operation requires manual operation, which greatly increases the workload and poses a risk of operational errors.

[0003] Based on this, a pear variety identification device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model achieves a more comprehensive effect of identifying pear varieties through an identification mechanism.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, a pear variety identification device includes a workbench 1, an mounting frame 11 on the upper surface of the workbench 1, a rotating disk 12 on the upper surface of the workbench 1 near the mounting frame 11, four contact switches 13 evenly distributed on the outer wall of the rotating disk 12, a stepper motor 14 fixedly connected to the inner wall of the workbench 1, the output end of the stepper motor 14 fixedly connected to the lower surface of the rotating disk 12, four placement slots evenly opened on the outer wall of the rotating disk 12, and the positions of the placement slots correspond to the contact switches 13, protective plates 15 evenly distributed on the upper surface of the rotating disk 12 near the placement slots, an ejection mechanism 2 is provided in the placement slots, an identification mechanism 3 for identifying pear varieties is provided on the top of the mounting frame 11, and an auxiliary mechanism 4 is provided on the upper surface of the workbench 1 near the rotating disk 12.

[0026] In this embodiment, the pear variety is identified by the identification mechanism 3. After the identification result is obtained, the identification information is transmitted to the auxiliary mechanism 4. Then, the stepper motor 14 drives the rotating disk 12 to rotate, so that the rotating disk 12 moves the pear in the placement slot. When it moves to the corresponding auxiliary mechanism 4, the contact switch 13 is triggered, so that the ejection mechanism 2 ejects the pear in the placement slot, so that the pear enters the auxiliary mechanism 4 and enters the collection box by the auxiliary mechanism 4.

[0027] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the ejection mechanism 2 includes a first electric push rod 21. The outer wall of the first electric push rod 21 is fixedly connected to the inner wall of the rotating disk 12. The first electric push rod 21 is electrically connected to the contact switch 13. An ejection plate 22 is fixedly connected to the output end of the first electric push rod 21. The outer wall of the ejection plate 22 is slidably connected to the inner wall of the placement groove. A limit block 23 is fixedly connected to the outer wall of the ejection plate 22. The outer wall of the limit block 23 is slidably connected to the inner wall of the rotating disk 12. When the first electric push rod 21 is activated, the ejection plate 22 moves upward in the inner cavity of the placement groove, causing the ejection plate 22 to move synchronously with the pear. When the inner wall of the ejection plate 22 is no longer in contact with the insertion plate 24, the pear naturally rolls down into the inclined platform 41 due to the inclination of the outer wall of the ejection plate 22.

[0028] In an optional embodiment, such as Figure 2 and Figure 3 As shown, insert plates 24 are inserted into the inner wall of the ejector plate 22. The insert plates 24 are evenly arranged in the placement slot. When the ejector plate 22 is not ejecting the pear, the insert plates 24 are fully inserted into the ejector plate 22. In this state, the pear is in contact with the insert plates 24, keeping the pear balanced and facilitating scanning and identification.

[0029] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the upper surface of the ejector plate 22 near the insert plate 24 is inclined at a certain angle. As the inner wall of the ejector plate 22 gradually disconnects from the insert plate 24, the pear gradually switches from contact with the insert plate 24 to contact with the outer wall of the ejector plate 22. Because the outer wall of the ejector plate 22 is inclined at a moving angle, the pear will roll on the outer wall of the ejector plate 22 when the ejector plate 22 is pushed upward, making it easier for it to enter the inclined platform 41.

[0030] In an optional embodiment, such as Figure 2 and Figure 4As shown, the identification mechanism 3 includes a first motor 31. The output end of the first motor 31 is fixedly connected to a fixed frame 32 through the outer wall of the mounting bracket 11. Teeth are evenly distributed on the inner sidewall of the fixed frame 32. A sliding seat 33 is slidably connected to the outer wall of the fixed frame 32. A second motor 35 is fixedly connected to the outer wall of the sliding seat 33. A hobbing gear 36 is fixedly connected to the output end of the second motor 35 through the outer wall of the sliding seat 33. The outer wall of the hobbing gear 36 meshes with the teeth. A pear variety identifier 37 is fixedly connected to the bottom end of the sliding seat 33. The first motor 31 drives the fixed frame 32 to rotate, and at the same time, the second motor 35 drives the hobbing gear 36 to rotate, so that the hobbing gear 36 meshes with the teeth on the inner sidewall of the fixed frame 32. This causes the sliding seat 33 to move on the outer wall of the fixed frame 32. The sliding seat 33 drives the slider 34 to slide synchronously on the inner wall of the fixed frame 32, thereby driving the pear variety identifier 37 to move synchronously. This allows the pear variety identifier 37 to perform a more comprehensive scan of the pear, which is beneficial for the pear variety identifier 37 to better identify the pear.

[0031] In an optional embodiment, such as Figure 2 and Figure 4 As shown, a slider 34 is fixedly connected to the inner wall of the sliding seat 33 near the fixed frame 32. The outer wall of the slider 34 is slidably connected to the inner wall of the fixed frame 32. The slider 34 limits the movement distance of the sliding seat 33 to prevent the sliding seat 33 from falling off the fixed frame 32.

[0032] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the sliding stroke limit of the slider 34 is earlier than the critical position where the hobbing gear 36 disengages from the teeth. Therefore, when the hobbing gear 36 engages with the teeth, it can not continue to move after moving a certain distance, thus preventing the slide seat 33 from falling off.

[0033] In an optional embodiment, such as Figure 2 and Figure 5 As shown, the auxiliary mechanism 4 includes three tilting platforms 41. The bottom end of the tilting platform 41 is fixedly connected to the upper surface of the worktable 1. A baffle 42 is fixedly connected to the top of the tilting platform 41. Rollers 43 are evenly distributed on the inner wall of the tilting platform 41 near the baffle 42. A second electric push rod 44 is fixedly connected to the inner wall of the tilting platform 41. The second electric push rod 44 is electrically connected to the pear variety identifier 37. A contact plate 45 is fixedly connected to the output end of the second electric push rod 44. The contact plate 45 has rounded corners near the outer wall of the rotating disk 12. After the pear variety identifier 37 identifies the variety, the second electric push rod 44 at the corresponding position receives the instruction and starts at a specified time to push out the contact plate 45. When the pear reaches the designated tilting platform 41, the contact plate 45 extended under the action of the second electric push rod 44 contacts the contact switch 13, thereby enabling the ejection mechanism 2 to work.

[0034] The above embodiment discloses a pear variety identification device. When identifying the variety of a pear, it is placed in a placement slot, and then a stepper motor 14 is started to rotate clockwise, causing the rotating disk 12 to rotate synchronously. This moves the pear in the placement slot directly below the pear variety identification instrument 37 (wherein the pear variety identification instrument 37 is existing technology, which mainly uses image recognition technology, spectral analysis, and other methods to quickly and accurately identify the pear variety). The pear variety identification instrument 37 then scans the pear. During the scanning process, a first motor 31 drives a fixed frame 32 to rotate, while a second motor 35 drives a gear hobbing device 36 to rotate, causing the gear hobbing device 36 to engage with the fixed frame 32. The teeth on the inner wall mesh, causing the sliding seat 33 to move on the outer wall of the fixed frame 32. The sliding seat 33 drives the slider 34 to slide synchronously on the inner wall of the fixed frame 32, thereby driving the pear variety identifier 37 to move synchronously. This allows the pear variety identifier 37 to perform a more comprehensive scan of the pear, which is beneficial for better identification. After the variety is identified, the second electric push rod 44 at the corresponding position receives a command. If the second electric push rod 44 closest to the placement slot (calculated according to the clockwise rotation distance) receives feedback information, the second electric push rod 44 will start immediately. If the second electric push rod 44 in the middle receives feedback information, the second pear will be processed. During variety scanning, the second electric push rod 44 is activated. If the second electric push rod 44, which is furthest away, receives feedback information, the second electric push rod 44 will be activated when the third pear is being scanned to avoid interference. When the pear reaches the designated tilting platform 41, the contact plate 45, which extends under the action of the second electric push rod 44, contacts the contact switch 13, activating the first electric push rod 21. This causes the ejector plate 22 to move upward within the placement slot, allowing the ejector plate 22 to move synchronously with the pear. When the inner wall of the ejector plate 22 is no longer in contact with the insertion plate 24, the pear naturally rolls down into the tilting platform 41 due to the tilt of the outer wall of the ejector plate 22. Then, roller 43 assists in making it slide down into the collection box (which is not shown in the figure), thus completing the variety identification and facilitating the collection of different varieties of pears into the corresponding collection boxes. In summary, the variety identification of pears is performed by the identification mechanism 3. After the identification result is obtained, the identification information is transmitted to the auxiliary mechanism 4. Then, the stepper motor 14 drives the rotating disk 12 to rotate, which moves the pear in the placement slot. When it moves to the corresponding auxiliary mechanism 4, the contact switch 13 is triggered, which causes the ejection mechanism 2 to eject the pear in the placement slot, so that the pear enters the auxiliary mechanism 4 and then enters the collection box from the auxiliary mechanism 4.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
