Description

Technical Field

[0001] The utility model relates to the technical field of plant cultivation racks, in particular to a stevia hybridization net rack. Background Art

[0002] Stevia is a perennial herbaceous plant of the Asteraceae family and the genus Stevia, native to the alpine grasslands on the border between Paraguay and Brazil in South America. Since 1977, it has been introduced and cultivated in Beijing, Hebei, Shaanxi, Jiangsu, Anhui, Fujian, Hunan, and Yunnan provinces in China. This species thrives in warm, humid environments and is sensitive to light. Stevia leaves contain steviol glycosides, which are 150 to 300 times sweeter than sucrose. It is a new natural sweetener with high sweetness, low calories, high quality, and safety and is widely used in the food, medical, and daily chemical industries. Hybridization is one of the main methods for developing new stevia varieties. Through hybridization, the genes controlling steviol glycoside synthesis from different parental lines can be combined to produce new varieties with high steviol glycoside content and good disease resistance, thereby increasing economic output.

[0003] In the existing technology, traditional hybridization technology usually requires manual pollen collection before the stevia flowers open, and then use a brush or small brush to dip the collected male parent pollen, and then gently apply it to the stigma of the female parent flower to complete the manual hybridization pollination operation.

[0004] However, in the prior art, since stevia is an economic crop with a wide planting area and quantity, the workload during hybridization is large and the work efficiency is low. Therefore, a stevia hybridization grid is proposed to solve the above problems. Utility Model Content

[0008] As a further description of the above technical solution:

[0009] The outer portion of the convex button contacts the inner portion of the arc groove, and the outer portion of the rotary disk contacts the outer portion of the arc clamp.

[0010] As a further description of the above technical solution:

[0011] The recording component comprises a classification slot, one side of which is fixedly connected to the outside of the frame, and a display card is slidably connected to the inside of the classification slot.

[0012] As a further description of the above technical solution:

[0013] The telescopic assembly includes a plurality of telescopic rods, the bottoms of the plurality of telescopic rods are slidably connected to the inside of the support column, the tops of the telescopic rods are fixedly connected to the bottom of the frame, and a U-shaped groove is provided on the outside of the telescopic rods.

[0014] As a further description of the above technical solution:

[0015] The outside of the support column is fixedly connected with a fixing ring, and the inside of the fixing ring is slidably connected with a U-shaped block.

[0016] As a further description of the above technical solution:

[0024] 2. In the utility model, the eccentric wheel is driven to rotate by prying open the pulling piece, thereby losing the squeezing force on the U-shaped block, and then the U-shaped block loses the friction fixing force with the telescopic rod. At this time, a single telescopic rod is slid, the height and horizontal angle of the device are adjusted, and then it is pried in the opposite direction and re-fixed, which can effectively overcome the problems caused by uneven ground and ensure the accuracy and effectiveness of pollination operations.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 3The utility model provides an embodiment: a stevia hybridization grid frame, including a frame 1 and a plurality of support columns 11. The frame 1 is a rectangular structure as a whole and is made of a sturdy and corrosion-resistant aluminum alloy metal material. It has the characteristics of light weight but high strength, and is suitable for carrying and providing support for hybridization. The interior of the frame 1 is fixedly connected with a split grid frame 2, which is also made of aluminum alloy metal to classify the internal stevia to avoid mutual interference in growth. The interior of the frame 1 is fixedly connected with a plurality of mounting plates 3, which are made of hard plastic plates to provide sliding limits for subsequent structures to ensure that they can slide and fix stevia for hybridization. The interior of the mounting plate 3 is slidably connected with two arc clamps 9. The arc clamp 9 is arc-shaped as a whole, and its curvature is adapted to the thickness of the stevia flower stem. It is made of a metal frame wrapped with rubber or plastic material with a certain degree of elasticity, so that it can gently clamp the stevia flower without causing damage to it. The rear side of the arc clamp 9 is fixedly connected with a convex button 10, which is a cylinder. By cooperating with the special groove of the subsequent structure, it drives the arc clamp 9 to slide and fix the stevia. The interior of the frame 1 is fixedly connected with multiple motors 6. The motor 6 is a small DC motor 6, which can provide stable power output for fixing the stevia hybrid. The driving end of the motor 6 is fixedly connected to the turntable 7. The turntable 7 is a round metal disk for receiving the driving power of the motor 6. An arc groove 8 is provided on the outside of the turntable 7. The arc groove 8 is in the shape of an arc groove, and the width matches the diameter of the convex button 10. The turntable 7 is driven to rotate by the motor 6. The cooperation between the arc groove 8 and the convex button 10 can accurately drive the arc clamp 9 to slide. The outside of the frame 1 is provided with a plurality of recording components for placing recording cards, and the inside of the support column 11 is provided with a telescopic component for adjusting the height of the grid. The outside of the convex button 10 is in contact with the inside of the arc groove 8, and the contact drives the convex button 10 and the arc clamp 9 to slide. The outside of the turntable 7 is in contact with the outside of the arc clamp 9, thereby making it possible for the turntable 7 to rotate.

[0034] Reference Figure 1 The recording component includes a classification slot 4, one side of which is fixedly connected to the outside of the frame 1. The classification slot 4 is an elongated groove structure as a whole and is made of transparent plastic. The content displayed by the internal structure can be clearly viewed. A display card 5 is slidably connected to the inside of the classification slot 4. The card can clearly record detailed data such as the variety name, source, planting date, fertilization and irrigation cycle, pest and disease control conditions, hybridization operation time, parent information, etc. of stevia. Agricultural personnel can quickly understand the past information and current status of each plant or group of stevia by checking the display card 5, providing strong information support for scientific management and precise hybrid breeding.

[0035] Reference Figures 4 and 5The telescopic assembly includes multiple telescopic rods 12, which are designed as cylindrical rod-shaped structures. The bottoms of the multiple telescopic rods 12 are all slidably connected to the inside of the support column 11. This sliding connection allows the telescopic rods 12 to move freely up and down relative to the support column 11, thereby achieving flexible adjustment of the height of the entire grid. The tops of the telescopic rods 12 are fixedly connected to the bottom of the frame 1, ensuring the stability of the frame 1 during height adjustment and equipment operation, making the entire hybrid grid structure stable and reliable. The outside of the telescopic rods 12 is provided with a U-shaped groove 14. Its main function is to cooperate with the subsequent structure to achieve locking and unlocking the position of the telescopic rods 12, thereby adjusting and fixing the height of the grid. The outside of the support column 11 is fixedly connected with a fixing ring 13, which is used to provide an installation foundation for the fixed structure. The inside of the fixing ring 13 is slidably connected with a U-shaped block 17. The material of the U-shaped block 17 is rubber. The U-shaped block 17 is made of rubber material. This rubber material has good elasticity and friction. The inside of the fixing ring 13 is rotatably connected with an eccentric wheel 15. The eccentric wheel 15 realizes the operation of fixing and separating by changing the diameter after rotation. The outside of the eccentric wheel 15 is fixedly connected with a pull member 16. The pull member 16 is generally a sheet structure, which is convenient for the operator to rotate the eccentric wheel 15 by pulling the pull member 16. The outside of the eccentric wheel 15 contacts the outside of the U-shaped block 17. After the eccentric wheel 15 rotates, it generates extrusion, which drives the U-shaped block 17 to slide. The outside of the U-shaped block 17 contacts the U-shaped groove 14, thereby increasing the contact area and increasing the friction during contact.

[0036] Working principle: First, agricultural personnel place the entire device in the stevia planting field, insert the bottom tip of the support column 11 into the ground, fix the device, and the internal dividing grid 2 classifies and plants the hybrid stevia. At this time, start the power switch of the motor 6, and the driving end is turned on to drive the turntable 7 to rotate. The arc groove 8 on the turntable 7 drives the two convex buttons 10 to produce downward relative movement, thereby driving the two arc clamps 9 to slide toward the adjacent side to bring the male and female stevia flowers to be hybridized together, waiting for their natural pollination, increasing the success rate of hybridization, and fixing the position of the male and female flowers through the device to reduce the workload of artificial pollination, adapt to large-scale pollination work scenes, and improve work efficiency.

[0037] Secondly, when the device is placed in a fixed installation at the planting site, due to the uneven ground, it is difficult to keep the top of the device in a horizontal state for close-coupled hybrid pollination. At this time, by prying open the trigger 16, the eccentric wheel 15 is driven to rotate, thereby losing the squeezing force on the U-shaped block 17, and then the U-shaped block 17 loses the friction fixing force with the telescopic rod 12. At this time, the single telescopic rod 12 is slid again, and the height and horizontal angle of the device are adjusted before being pried back and re-fixed. This greatly enhances the device's adaptability to complex terrain. In actual stevia planting sites, the ground is often not completely flat, and there are various ups and downs and tilts. The device, with its ingenious height and horizontal angle adjustment design, can effectively overcome the problems caused by uneven ground and ensure that the top of the device can always be in a horizontal state suitable for hybrid pollination. This not only ensures the accuracy and effectiveness of the pollination operation.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
