Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheat breeding technology, and in particular to a wheat hybridization isolation and protection breeding device. Background Technology
[0002] Wheat hybridization breeding refers to crossing two wheat varieties with different genetic backgrounds to produce offspring with new characteristics. Through hybridization, the superior traits of the two parents can be combined to cultivate better varieties.
[0003] Existing wheat hybridization breeding methods employ the isolation of maternal and paternal parents to prevent the invasion of non-target pollen. However, after the pollen on the paternal parent matures, artificial pollination is required, which is labor-intensive. Furthermore, artificial pollination can easily lead to the invasion of non-target pollen, affecting the analysis of hybridized plants. To address these technical drawbacks, we propose a wheat hybridization isolation and protection breeding device. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wheat hybridization isolation and protection breeding device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A wheat hybrid isolation and protection breeding device includes several sets of female parent isolation boxes and male parent isolation boxes, with an automatic pollination mechanism installed between the female parent isolation boxes and the male parent isolation boxes. The automatic pollination mechanism includes a left-bent pipe, a middle support cylinder, and a right-bent pipe. Ventilation holes are provided on the side walls of both the female parent isolation boxes and the male parent isolation boxes. A drive motor is installed inside the middle support cylinder, and several connecting rods are fixedly connected between the drive motor and the inner wall of the middle support cylinder. A turntable is fixedly installed on the output end of the drive motor, and several fan blades are fixedly installed on the turntable. Connecting flanges are fixedly installed at the ports of the left-bent pipe, the middle support cylinder, and the right-bent pipe, and the connecting flanges are screwed onto the outside of the ventilation holes.
[0007] Furthermore, a sealing gasket is provided at several of the connecting flange ports.
[0008] Furthermore, the parent isolation box and the parent isolation box are rotatably mounted with flip-tops on their upper sides. The flip-tops are made of transparent material and are equipped with a filter mechanism.
[0009] Furthermore, the filtration mechanism includes an air vent, which is fixedly installed on the upper side of the flip cover. A screw ring is screwed onto the outer side of the air vent, and a filter screen is provided between the air vent and the screw ring.
[0010] Furthermore, an annular groove is provided at the outer end of the venting cylinder, and an annular frame is fixedly installed on the outer side of the filter screen, with the annular frame located inside the annular groove.
[0011] Furthermore, a lock hole is provided on the side of the flip cover, and a locking mechanism is provided on the side wall of both the mother and father isolation boxes.
[0012] Furthermore, the locking mechanism includes a sealing box, a slide rod is slidably installed inside the sealing box, a spring is fixedly connected between the slide rod and the inner wall of the sealing box, a locking block is fixedly connected to the inner end of the slide rod, and the locking block slides through to the outside of the sealing box and the size of the locking block is adapted to the lock hole.
[0013] Furthermore, the spring is a compression spring, and a pull plate is fixedly installed on the outer end of the slide rod.
[0014] Furthermore, structural base plates are fixedly installed at the bottom of the maternal isolation box and the paternal isolation box.
[0015] Furthermore, a master control switch is fixedly installed on the upper side of the structural base plate.
[0016] Compared with related technologies, the wheat hybridization isolation and protection breeding device proposed in this utility model has the following beneficial effects:
[0017] This invention relates to a wheat hybridization isolation and protection breeding device. An automatic pollination mechanism connects the maternal and paternal parent isolation boxes via a combination of a left-bent pipe, a central support cylinder, and a right-bent pipe. Activating the drive motor in the central support cylinder rotates a turntable, which in turn drives the outer fan blades of the turntable to rotate synchronously. The rotation of the fan blades promotes the flow of pollen from the paternal parent plants in the paternal parent isolation box into the maternal parent isolation box through the combination of the left-bent pipe, central support cylinder, and right-bent pipe. This allows the pollen from the paternal parent to circulate into the maternal parent's growth space, completing the automatic pollination process. This invention, by combining the maternal parent isolation box, the automatic pollination mechanism, and the paternal parent isolation box, forms a hybridization experimental group. Activating the drive motor allows pollen from the paternal parent plants to flow into the maternal parent isolation box through the combination of the left-bent pipe, central support cylinder, and right-bent pipe, completing the automatic pollination process. The entire pollination process is isolated from the outside environment, preventing the intrusion of non-target pollen and reducing the inconvenience of manual pollination.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] Reference Figure 1-6 A wheat hybrid isolation and protection breeding device includes several sets of maternal isolation boxes 3 and paternal isolation boxes 4, with an automatic pollination mechanism 5 installed between the maternal isolation boxes 3 and paternal isolation boxes 4. The automatic pollination mechanism 5 includes a left-bent pipe 51, a middle support cylinder 52, and a right-bent pipe 53. Ventilation holes 6 are provided on the side walls of both the maternal isolation boxes 3 and paternal isolation boxes 4. A drive motor 57 is provided inside the middle support cylinder 52. Several connecting rods 56 are fixedly connected between the drive motor 57 and the inner wall of the middle support cylinder 52. A turntable 58 is fixedly installed on the output end of the drive motor 57. Several fan blades 59 are fixedly installed on the turntable 58. Connecting flanges 54 are fixedly installed at the ports of the left-bent pipe 51, the middle support cylinder 52, and the right-bent pipe 53. The connecting flanges 54 are screwed onto the outside of the ventilation holes 6.
[0027] In this method, a structural base plate 1 is fixedly installed at the bottom of the mother isolation box 3 and the father isolation box 4, and a master control switch 2 is fixedly installed on the upper side of the structural base plate 1.
[0028] With the above-mentioned settings, the master control switch 2 is used to control the working state of the drive motor 57, and thus to control the automatic pollination process.
[0029] In this method, a sealing gasket 55 is provided at several connection flange ports 54.
[0030] By setting up the sealing gasket 55 as described above, the connection between the left bend 51, the middle support cylinder 52, and the right bend 53 maintains good sealing performance.
[0031] In this method, a flip cover 7 is rotatably installed on the upper side of the parent isolation box 3 and the parent isolation box 4. The flip cover 7 is made of transparent material and a filter mechanism 8 is installed on the flip cover 7. The filter mechanism 8 includes a vent cylinder 81, which is fixedly installed on the upper side of the flip cover 7. A screw ring 82 is screwed onto the outer side of the vent cylinder 81. A filter screen 85 is provided between the vent cylinder 81 and the screw ring 82. An annular groove 83 is opened at the outer end of the vent cylinder 81. An annular frame 84 is fixedly installed on the outer side of the filter screen 85 and is located inside the annular groove 83.
[0032] With the above-mentioned setup, the filter screen 85 allows the mother isolation box 3 and the father isolation box 4 to maintain ventilation with the outside world while preventing external pollen from mixing with its interior. This ensures ventilation while preventing interference from non-target pollen. In addition, the entire filter screen 85 is pressed into the inner side of the annular groove 83 at the end of the air vent 81 by the outer screw ring 82, which facilitates disassembly, cleaning or replacement of the filter screen 85 in the future.
[0033] In this method, a lock hole 71 is provided on the side of the flip cover 7. Locking mechanisms 9 are provided on the side walls of the mother isolation box 3 and the father isolation box 4. The locking mechanism 9 includes a sealing box 91. A slide rod 92 is slidably installed inside the sealing box 91. A spring 94 is fixedly connected between the slide rod 92 and the inner wall of the sealing box 91. A locking block 95 is fixedly connected to the inner end of the slide rod 92. The locking block 95 slides through to the outside of the sealing box 91 and the size of the locking block 95 is adapted to the lock hole 71. The spring 94 is a compression spring. A pull plate 93 is fixedly installed on the outer end of the slide rod 92.
[0034] With the above-mentioned setup, under the rebound force of the compression spring 94, the slide bar 92 is driven to slide inward, thereby driving the locking block 95 to lock into the inside of the lock hole 71 on the flip cover 7, thus completing the locking function of the flip cover 7.
[0035] The working principle of the wheat hybrid isolation and protection breeding device provided by this utility model is as follows:
[0036] In use, the female wheat is placed in the female isolation box 3 and the male wheat is placed in the male isolation box 4 for separate cultivation. During cultivation, the flip cover 7 is kept closed to keep the female isolation box 3 and the male isolation box 4 isolated from the outside world. When the pollen of the male plant in the male isolation box 4 matures, the drive motor 57 is started to drive the turntable 58 to rotate, and the fan blades 59 on the outside of the turntable rotate synchronously. Under the action of the fan blades 59, the pollen in the male plant in the male isolation box 4 is promoted to enter the female isolation box 3 through the right bend pipe 53, the middle support cylinder 52 and the left bend pipe 51, so that the pollen in the male plant can flow into the growth space of the female plant, thus completing the automatic pollination work.
[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
