Description

Technical Field

[0001] The utility model relates to the technical field of wheat breeding, in particular to a new variety wheat hybrid breeding device. Background Art

[0002] Wheat is a type of crop that can be eaten as a staple food. It is mainly grown in temperate regions. When planting, it is necessary to choose suitable temperatures and appropriate precipitation. Food made from wheat is rich in nutrients such as carbohydrates and vitamins.

[0003] When carrying out hybrid breeding of new varieties of wheat, a pollination device is needed. The pollination device can assist the hybrid breeding of wheat and further affect the growth quality of wheat. The existing pollination device has components such as air bags installed on the outside of the pollination tube, and pollen can be blown out through the air bags for pollination. However, there is only one nozzle for exhausting and inhaling air inside the device. When in use, moisture in the environment will enter the inside of the pollination tube during the inhalation process. Since there is no structure for processing moisture, the wetted pollen will easily block the tube mouth or be adsorbed on the inner wall of the pipe, causing pollination failure. In order to solve this technical problem, the utility model proposes a new variety wheat hybrid breeding device. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, through the cooperation among the elastic pull rope, the filter block and the sealing plate 1, the piston block is controlled to evacuate air to the inside of the pollination shell during pollination. At this time, the piston block can pull the sealing plate 1 to close the entrance of the conical cylinder through the elastic pull rope. At this time, the sealing plate 2 is opened under the internal negative pressure, and air can be evacuated through the fixed cylinder 1.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, a new variety wheat hybrid breeding device includes a pollination shell 1, one end of the pollination shell 1 is detachably connected to a connecting head 2, a conical cylinder 3 is fixedly installed inside the connecting head 2, a sealing gasket is installed inside the conical cylinder 3, the outer surface of the conical cylinder 3 is rotatably connected to a sealing plate 4, the outer surface of the sealing plate 4 is in contact with one end of the conical cylinder 3, and the sealing plate 4 can seal the interior of the conical cylinder 3 when it contacts the opening of the conical cylinder 3.

[0023] An elastic pull rope 5 is fixedly installed on one side of the sealing plate 4, and a piston block 6 is fixedly installed on one end of the elastic pull rope 5. The outer surface of the piston block 6 contacts the inner wall of the pollination shell 1, and a support rod 7 is fixedly installed on one side of the piston block 6. When the piston block 6 evacuates air, the sealing plate 4 seals the inside of the connecting head 2. When the piston block 6 inflates air, the sealing plate 4 opens. When the piston block 6 moves, the sealing plate 4 can be pulled to rotate by the elastic pull rope 5. At this time, the sealing plate 4 can automatically seal the inside of the conical cylinder 3.

[0024] The outer surface of the support rod 7 is slidably connected to the inside of the pollination shell 1, and the outer surface of the support rod 7 is threadedly connected with a positioning bolt 14, which is threadedly connected to one end of the support rod 7. The position of the support rod 7 can be fixed by the positioning bolt 14, which is convenient for fixing the position of the piston block 6.

[0025] The interior of the pollination shell 1 is connected to a fixed cylinder 2 15, and a perforated plate 16 is provided inside the fixed cylinder 2 15. An adjusting plate 17 is rotatably connected to the upper surface of the perforated plate 16. A powder storage tank 18 is detachably connected to the interior of the fixed cylinder 2 15. Through holes in the same position are provided inside the orifice plate 16 and the adjusting plate 17. The sizes of the through holes of the two can be adjusted by rotating the adjusting plate 17, and the powder output can be quickly adjusted, which is very convenient to use.

[0026] The interior of the pollination shell 1 is connected to a fixed cylinder 8, and a filter block 9 is placed inside the fixed cylinder 8. When the interior of the conical cylinder 3 is sealed, the interior of the fixed cylinder 8 can be ventilated. At this time, external air can enter the interior of the fixed cylinder 8, and the moisture in the air can be removed through the filter block 9, ensuring that the moisture content of the air entering the pollination shell 1 is low.

[0030] When in use, the pollen output of the adjusting plate 17 and the orifice plate 16 can be adjusted by rotating the adjusting plate 17. At this time, the support rod 7 is pulled to exhaust air into the pollination shell 1. When the piston block 6 moves, the sealing plate 4 can be pulled by the elastic pull rope 5 to close one end of the conical cylinder 3. At this time, the sealing plate 2 12 will be opened under the action of the internal pressure, and the inside of the fixed cylinder 8 will be opened. At this time, air can enter the interior of the pollination shell 1 through the fixed cylinder 8, and moisture in the air can be removed by the filter block 9.
