Abstract
Description
Technical Field
[0001] This utility model relates to the field of quinoa cultivation technology, and in particular to a protective cover for quinoa cultivation. Background Technology
[0002] Quinoa is a highly nutritious grain crop. It is an annual herbaceous plant with a broom-like shape, a distinct main stem and branches. The main stem is upright and cylindrical, with a relatively regular overall shape. The stem is quite hard, with a certain degree of toughness and strength, which can support the growth of the plant and the weight of the fruit, making it less likely to fall over in the natural environment.
[0003] In the process of quinoa germplasm resource cultivation, various methods are needed to ensure that the genetic composition of quinoa offspring achieves a high degree of consistency and purity, so as to guarantee the stable transmission of excellent agronomic traits, quality characteristics, and other genetic characteristics to the offspring. Currently, in the process of quinoa germplasm resource cultivation, the ears are often protected by plastic protective bags to prevent outer pollen from entering due to insect, wind, or human interference, which could affect the purity of the grains. This also provides rain protection, ensuring self-pollination of quinoa.
[0004] However, existing plastic protective bags have poor support capacity. When it rains, they are easily deformed by the impact of rainwater and collide with the spike, causing the flowers to fall off. In addition, the plastic protective bags have poor light transmission, waterproof performance and air permeability, which can easily affect the photosynthetic efficiency after covering the spike. Utility Model Content
[0005] To address the technical problem in the existing quinoa germplasm resource cultivation process mentioned above, where plastic protective bags are used to cover and protect the spikelets, but these bags have poor deformation resistance and easily cause the flowers to fall off, this utility model provides a protective cover for quinoa cultivation.
[0006] The technical solution of this utility model is as follows:
[0007] This utility model provides a protective cover for quinoa cultivation, including an elastic outer cover with a support frame inside. The support frame includes a connecting plate and an annular buckle. Several inclined first support rods are arranged at intervals along the circumference of the connecting plate. The first support rods are hinged to the annular buckle through second support rods. The annular buckle is used to snap onto the main stem of quinoa. The support frame is detachably installed on the main stem of quinoa, thereby supporting the outer cover covering the outside of the quinoa spike. The outer cover, under the action of elasticity, covers the periphery of the support frame to protect the spike, prevent the outer cover from deforming and knocking off the flowers, and effectively block the entry of external pollen, preventing hybridization from affecting the self-pollination of quinoa and ensuring high purity of the grains.
[0008] Preferably, the outer protective cover includes a waterproof and light-transmitting layer and a honeycomb support layer. The waterproof and light-transmitting layer is located on the outside of the honeycomb support layer. The waterproof and light-transmitting layer has excellent hydrophobic properties, which can effectively prevent external moisture from entering and greatly reduce the risk of ear germination. The honeycomb support layer provides the necessary support strength for the waterproof and light-transmitting layer while also preventing direct contact between the waterproof and light-transmitting layer and the support, thus effectively avoiding damage to the waterproof and light-transmitting layer.
[0009] Preferably, the waterproof and light-transmitting layer is an ETFE film, which can effectively block external pollen from entering, avoid hybridization affecting the self-pollination of quinoa, ensure high purity of the grains, and ensure that quinoa can carry out normal photosynthesis inside the protective cover. The honeycomb support layer is a honeycomb PP mesh, which provides the necessary support strength for the waterproof and light-transmitting layer while avoiding direct contact between the waterproof and light-transmitting layer and the support, effectively preventing damage to the waterproof and light-transmitting layer.
[0010] Preferably, a plurality of first connecting ears are fixedly provided on the lower surface of the connecting plate at circumferential intervals, and second connecting ears are fixedly provided at both ends of the first support rod. The first connecting ears and the second connecting ears are connected by bolts, and the included angle between the first support rod and the connecting plate can be adjusted as needed to meet different usage requirements.
[0011] Preferably, the two ends of the second support rod are fixedly provided with third connecting ears, and the upper surface of the annular buckle is fixedly provided with a plurality of fourth connecting ears at intervals along its circumference. The third connecting ears are hinged to the corresponding second connecting ears and fourth connecting ears through pins, so that the relative angle between the first support rod and the second support rod can be quickly adjusted according to the needs to meet different usage requirements.
[0012] Preferably, the annular buckle is provided with several ventilation holes at intervals along its circumference. The ventilation holes penetrate the annular buckle vertically, which can ensure ventilation and timely discharge of water vapor and heat generated by the respiration of quinoa ears, reducing the risk of mold and germination in the ears. At the same time, the vertically arranged ventilation holes can also effectively prevent pollen from being blown into the outer protective cover.
[0013] Preferably, the annular buckle includes a semi-annular first buckle and a second buckle. The first buckle is hollow inside, and slots are formed on the lower surfaces of both ends of the first buckle, which penetrate the side wall of the first buckle. The second buckle has locking parts fixed at both ends, which are inserted into the first buckle. The locking parts are fixed with claws for cooperating with the slots. By cooperating with the slots, the first buckle and the second buckle can be quickly connected and disconnected, which is convenient for use.
[0014] Preferably, the inner ring of the ring buckle is detachably fitted with a rubber layer. The rubber layer is arranged along the circumferential direction of the ring buckle. On the one hand, it plays a role in flexible contact, avoiding hard contact between the ring buckle and the quinoa main stem, which would cause damage to the main stem. On the other hand, rubber layers with different inner diameters can be replaced by disassembly to adapt to quinoa main stems of different sizes.
[0015] As can be seen from the above technical solutions, the advantages of this utility model are:
[0016] 1. A support frame is installed inside the outer cover. The support frame can be detachably installed on the main stem of quinoa through ring buckles, thereby supporting the outer cover covering the outside of the quinoa ear. The outer cover, under the action of elasticity, covers the periphery of the support frame to protect the ear, prevent the outer cover from deforming and knocking off the flowers, and can effectively block the entry of external pollen, avoid hybridization affecting the self-pollination of quinoa, and ensure the high purity of the grains.
[0017] 2. The bracket contains an adjustable first support rod and a second support rod. The angle adjustment of the first support rod and the second support rod can adapt to the protection of tassels of different sizes to meet different usage needs.
[0018] 3. Several ventilation holes are provided along the circumferential direction of the ring buckle. The ventilation holes penetrate the ring buckle vertically. While ensuring ventilation, they can promptly release the water vapor and heat generated by the respiration of quinoa ears, reducing the risk of mold and germination in the ears. At the same time, the vertical ventilation holes can also effectively prevent pollen from being blown into the outer protective cover. Attached Figure Description

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0027] Example 1
[0028] In a typical embodiment of this utility model, such as Figures 1-4 As shown, a protective cover for quinoa cultivation is proposed, comprising: an outer cover 1 and a support 4. The support 4 is located inside the outer cover 1 to support the outer cover 1. The support 4 is detachably installed on the main stem of quinoa to support the outer cover 1 covering the outside of the quinoa spike. The outer cover 1, under the action of elasticity, covers the periphery of the support 4 to protect the spike, prevent the outer cover 1 from deforming and knocking off the flowers, and facilitate the self-pollination of quinoa.
[0029] The outer protective cover 1 includes a waterproof and light-transmitting layer 2 and a honeycomb support layer 3. The waterproof and light-transmitting layer 2 is a 0.1mm thick ETFE film (95% light transmittance, tensile strength ≥45MPa), which can effectively block the entry of external pollen, avoid hybridization affecting the self-pollination of quinoa, and ensure high purity of the grains. It can also ensure that quinoa can carry out photosynthesis normally inside the protective cover. The outer side of the ETFE film is equipped with a nano-SiO2 hydrophobic coating (contact angle >150°), which has excellent hydrophobic properties and can effectively prevent external water intrusion, greatly reducing the risk of ear germination.
[0030] The honeycomb support layer 3 is a honeycomb PP mesh (porosity 65%±5%), which provides the necessary support strength for the waterproof and light-transmitting layer 2, while also preventing direct contact between the waterproof and light-transmitting layer 2 and the support 4, effectively avoiding damage to the waterproof and light-transmitting layer 2.
[0031] It is understandable that the waterproof and light-transmitting layer 2 and the honeycomb support layer 3 can be fixed together by adhesive; or they can be a separate structure, that is, when in use, the honeycomb support layer 3 and the waterproof and light-transmitting layer 2 are put on the bracket 4 in the order of inside and outside. The specifics can be determined according to the actual design requirements, and no further restrictions are imposed here.
[0032] In this embodiment, the outer cover 1 has an opening, and the opening is an elastic closing structure, such as a rubber band for closing the opening. The opening can fit tightly with the bracket 4 under the action of elasticity. At the same time, the cover of the outer cover 1 is elastic due to the influence of its own material properties, and can fit on the bracket 4 after being stretched and deformed.
[0033] like Figure 2 As shown, the bracket 4 includes a connecting plate 5, a first support rod 6, a second support rod 7, and an annular buckle 8. There are several first support rods 6 and 7. The connecting plate 5 is a circular plate. Several first connecting ears 11 are fixedly provided at intervals along the circumference on the lower surface of the connecting plate 5. Second connecting ears 12 are fixedly provided at both ends of the first support rod 6. Third connecting ears 13 are fixedly provided at both ends of the second support rod 7. Several fourth connecting ears 14 are fixedly provided at intervals along the circumference on the upper surface of the annular buckle 8. Each first connecting ear 11 is connected to an inclined first support rod 6. The first support rod 6 is hinged to the annular buckle 8 through the second support rod 7.
[0034] Specifically, the second connecting ear 12 on one end of the first support rod 6 is fixedly connected to the first connecting ear 11 on the lower surface of the connecting plate 5 by bolts 9, which can adjust the angle between the first support rod 6 and the connecting plate 5 as needed. The second connecting ear 12 on the other end of the first support rod 6 is hinged to the third connecting ear 13 at the end of the second support rod 7 by pin 10. The third connecting ear 13 at the other end of the second support rod 7 is hinged to the fourth connecting ear 14 on the annular buckle 8 by pin 10. The annular buckle 8 is used to fasten and fix it on the main stem of quinoa to limit the overall position of the support 4 and the outer cover 1. In actual use, the angle between the first support rod 6 and the connecting plate 5 can be changed by changing the angle between the first support rod 6 and the connecting plate 5, as well as the relative position between the annular buckle 8 and the connecting plate 5, thereby changing the angle between the first support rod 6 and the second support rod 7 to meet the protection needs of different sized ears of grain.
[0035] Both the first support rod 6 and the second support rod 7 are hollow structures to reduce the overall weight of the bracket 4. In this embodiment, the first support rod 6 and the second support rod 7 are straight rods; in other embodiments, the first support rod 6 and the second support rod 7 can also be curved rods. The specific design can be determined according to actual needs, and no further restrictions are imposed here.
[0036] like Figure 3As shown, the annular buckle 8 includes a first fastener 15 and a second fastener 16. Both the first fastener 15 and the second fastener 16 are semi-annular structures. The first fastener 15 is hollow inside, and slots 17 are provided on the lower surfaces of both ends of the first fastener 15, which penetrate the sidewalls of the first fastener 15. Both ends of the second fastener 16 are fixedly provided with snap-fit parts 18, which are used to be inserted into the first fastener 15. Slippers 19 are fixedly provided on the snap-fit parts 18, which are used to cooperate with the slots 17 to realize the quick connection and disassembly between the first fastener 15 and the second fastener 16.
[0037] The ring buckle 8 has several vent holes 20 spaced around its circumference. The vent holes 20 penetrate vertically through the upper and lower surfaces of the ring buckle 8 to allow outside air to enter the outer cover 1. This facilitates air circulation inside the outer cover 1 and ensures ventilation while timely expelling moisture and heat generated by the respiration of the quinoa ears, reducing the risk of mold and germination in the ears. At the same time, the vertically arranged vent holes 20 can also effectively prevent pollen from being blown into the outer cover 1.
[0038] The inner ring of the ring buckle 8 is detachably fitted with a rubber layer 21. The rubber layer 21 is arranged along the circumference of the ring buckle 8. On the one hand, it plays a role in flexible contact, avoiding hard contact between the ring buckle 8 and the quinoa main stem, which would cause damage to the main stem. On the other hand, the rubber layer 21 with different inner diameters can be replaced by disassembly to adapt to quinoa main stems of different sizes.
[0039] like Figure 4 As shown, the inner rings of the first fastener 15 and the second fastener 16 are provided with mounting grooves 22. The cross-section of the mounting grooves 22 is T-shaped. The sidewall of the rubber layer 21 is fixed with an insertion part 23 along its circumferential direction. The cross-section of the insertion part 23 is T-shaped. The insertion part 23 can be inserted into the corresponding mounting groove 22 from the end of the first fastener 15 and the second fastener 16 to realize the rapid installation of the rubber layer 21.
[0040] During the quinoa grain cultivation process, the corresponding rubber layer 21 is first replaced according to the size of the main stem. Then, the angle between the first connecting rod 6 and the connecting plate 5 is adjusted, and the support 4 is placed on the outside of the corresponding quinoa ear. The first fastener 15 and the second fastener 16 are moved to the designated position and fastened. The position of the support 4 is fixed by the clamping of the main stem by the rubber layer 21. Then, the outer cover 1 is placed on the support 4. The outer cover 1 covers and adheres to the support 4 under its own elasticity to complete the covering and protection of the ear.
[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
