Description

Technical Field

[0001] The utility model relates to the technical field of corn seedling cultivation, in particular to a corn breeding isolation cover. Background Art

[0002] Corn breeding is a measure taken to improve the cultivation management level of corn seed production and achieve high yield and high quality. Since corn is a unisexual flower and cross-pollination, it does not need to be emasculated during hybridization, and therefore does not need to be whole ear. Its hybridization method and steps mainly include adjusting the flowering period, selecting plants, isolating, collecting pollen, pollinating and harvesting. Generally, corn can be pollinated naturally, but sometimes in order to achieve the hybridization of a specified variety, or due to other reasons, when the pollination rate of corn is low, artificial pollination is required. After artificial pollination of corn, in order to prevent the pollen on the plant from falling off and floating in the wind, an isolation cover is usually used to isolate and protect the corn plant. However, during use, the conventional isolation cover is usually fully supported and placed on the corn plant, and it is easy to swing with the corn plant, causing the pollen on the corn plant to scatter, and the isolation cover is inconvenient to adapt to corn plants of different widths. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] In view of the deficiencies in the prior art, the utility model provides a corn breeding isolation cover, which solves the problem that the conventional isolation cover is easily swayed in the wind with the corn plants during use, causing the pollen on the corn plants to scatter, and the isolation cover is not convenient to adapt to corn plants of different widths.

[0005] (II) Technical solution

[0010] Preferably, both ends of the right-angle shaft are threaded sections, and one end of the right-angle shaft is threadedly connected to the auxiliary rod frame.

[0011] Preferably, a connecting sleeve is fixedly connected to the top end of the isolation cover, and an inner cavity of the connecting sleeve is provided with an internal thread and is threadedly connected to one end of the right-angle shaft.

[0012] (III) Beneficial effects

[0013] The utility model has the following beneficial effects:

[0014] The corn breeding isolation cover can stably support the main pole and the auxiliary pole frame through the provided base plate and the ground-inserted pole, and further can stably support the right-angle axis and the isolation cover installed thereon. Since an isolation membrane and an elastic ring are provided at the lower part of the isolation cover, when a person sets the entire isolation cover on the corn plant, the elastic ring is deformed and then stretches the isolation membrane, thereby increasing the opening on it, so that the person can smoothly complete the installation of the isolation cover. Since the surface area of ​​the flat isolation membrane is larger than the area of ​​the circle formed by the lower end surface of the isolation cover, the isolation membranes are folded or stacked under normal conditions. Therefore, when the elastic ring is stretched, the isolation membrane will not be damaged due to stretching, and can well meet the isolation and protection needs of corn plants of different widths.

Since the isolation cover 10 is provided with an isolation membrane 11 and an elastic ring 12 at the lower part, when a person sets the entire isolation cover 10 on the corn plant, the elastic ring 12 is deformed and then stretches the isolation membrane 11, thereby increasing the opening on the isolation membrane 11, so that the person can smoothly complete the installation of the isolation cover 10.

[0022] Reference Figure 1 and 3 As shown, in this embodiment, a plurality of extrusion sheets 7 are evenly distributed in an annular pattern on the upper end of the main rod 3, the inner side wall of the extrusion sheet 7 is in contact with the auxiliary rod frame 4, a threaded portion 5 is provided on the upper portion of the main rod 3, and a pressure sleeve 6 is threadedly connected to the upper portion of the main rod 3. The pressure sleeve 6 can continuously apply pressure to the extrusion sheet 7 during the movement of the main rod 3. When the isolation cover 10 needs to be raised, the pressure on the extrusion sheet 7 can be reduced by twisting the pressure sleeve 6, thereby reducing the friction between the extrusion sheet 7 and the auxiliary rod frame 4, so that personnel can manually determine the length of the auxiliary rod frame 4, and then change the height of the isolation cover 10 to meet the shielding requirements of corn plants of different heights.

[0023] Reference Figure 2 As shown, in this embodiment, a plurality of semi-cylindrical protrusions are evenly arranged on the outer circumference of the pressure sleeve 6.
