Description

Technical Field

[0001] The utility model relates to the technical field of millet breeding, in particular to a millet mutation breeding device. Background Art

[0002] Broomcorn millet is native to northern China and widely distributed in the arid areas of northern China. It is mainly planted in dryland agricultural areas with drought in spring and summer and poor soil. At present, in order to cultivate new varieties or germplasm of broomcorn millet, the seeds of broomcorn millet are generally subjected to mutation breeding. The methods of mutation breeding can be divided into two types: physical method and chemical method. The chemical method is to use chemical mutagens to treat various parts or tissues of the plant to cause mutations, and then screen mutants for breeding, and finally cultivate new varieties. However, the existing broomcorn millet mutation breeding device uses a corresponding mesh basket to hold broomcorn millet seeds, and then soaks them in a breeding box or cylinder filled with chemical agents. The mesh basket is generally fixed in the breeding box cylinder, which causes some seeds to be unable to effectively contact the agent, affecting the effect of mutation breeding. Therefore, a broomcorn millet mutation breeding device is developed. Utility Model Content

[0016] like Figure 1-Figure 2 As shown, a millet mutation breeding device includes a breeding cylinder 1, and a plurality of liquid supply pipes 2 connected to the inside of the breeding cylinder are installed on the side of the breeding cylinder. A plurality of vertical support legs 3 are evenly fixedly installed along the circumference at the bottom of the breeding cylinder 1 near the outer edge, and a drainage pipe 4 connected to the inside is installed in the middle of the bottom of the breeding cylinder 1. An on-off valve 5 is provided on each of the liquid supply pipes 2 and the drainage pipe 4, and each of the liquid supply pipes 2 is respectively connected to a medicine tank, and the chemical agent used for mutation breeding of millet seeds is input into the inside of the breeding cylinder 1 through each of the liquid supply pipes 2. After the breeding is completed, the agent can be discharged from the drainage pipe 4.

[0017] The top open end of the breeding cylinder 1 is lifted and provided with a cylinder cover 6 that matches it. Specifically, two horizontal mounting seats 7 are symmetrically fixed at the lower end of the outer wall of the breeding cylinder 1, and vertical electric telescopic rods 8 are fixedly installed on the two mounting seats 7 respectively. The telescopic ends of the two electric telescopic rods 8 are fixedly connected to two connecting ears 9 fixedly provided on the outer ends of the cylinder cover 6 respectively.

[0018] A driving motor 10 is fixedly installed in the middle of the upper part of the cylinder cover 6, and the driving shaft of the driving motor 10 passes through the top plate of the cylinder cover 6 and is fixedly connected to the upper part of the turntable 11. A sleeve 12 is fixedly installed at the bottom of the turntable 11, and the inner peripheral wall of the sleeve 12 is provided with an internal thread. A seed cylinder for holding millet seeds is detachably installed on the sleeve 12, and the seed cylinder includes a connecting sleeve 13 connected to the sleeve 12 and a net cylinder 14 fixedly arranged at the bottom of the connecting sleeve 13, and the mesh size of the net cylinder 14 is smaller than the size of the millet seeds. The outer peripheral wall of the connecting sleeve 13 is provided with an external thread that matches the internal thread of the sleeve 12.

[0019] In addition, the portion near the lower end of the sleeve 12 is provided with a first sliding hole 15 and a second sliding hole 16 in sequence from the inside to the outside in the radial direction, and the inner diameter of the first sliding hole 15 is smaller than that of the second sliding hole 16. A sliding rod 17 is slidably mounted on the first sliding hole 15, one end of which is located outside the sleeve 13 and fixedly provided with a pull rod 18. The other end of the sliding rod 17 is located in the second sliding hole 16 and fixedly provided with a limit clamp 19 that is slidably matched with the second sliding hole 16. The sliding rod 17 is provided with a spring 20 at a portion between the bottom end of the second sliding hole 16 and the limit clamp 19, and the connecting sleeve 13 is provided with a limit clamping groove 21 that is matched with the limit clamp 19.

[0020] The seed barrel of the utility model can be detachably connected to the sleeve at the bottom of the turntable. Before installing the seed barrel, the entire barrel cover is located a certain distance above the open end of the breeding barrel body. After the millet seeds to be induced to undergo mutation are placed inside the seed barrel, the connection sleeve and the sleeve can be fixedly connected by threaded connection. In addition, during the process of rotating and installing the seed barrel, the operator can pull the pull rod outward to make the limit clamp head located in the second sliding hole. After the connection sleeve of the seed barrel is fully matched with the sleeve, the pull rod is released, and the limit clamp head is matched with the limit clamping groove on the connection sleeve under the action of the spring, thereby further clamping and fixing the seed barrel.

[0021] After the seed barrel is installed, the two electric telescopic rods are retracted to allow the seed barrel to completely enter the inside of the breeding barrel, and the barrel cover seals the open end of the breeding barrel. Then the drive motor can be turned on at a fixed time to drive the turntable and the sleeve and seed barrel to rotate synchronously. During the rotation of the seed barrel, the millet seeds inside it can be fully in contact with the liquid of the breeding barrel, which is conducive to ensuring the effect of mutagenesis breeding. After the predetermined soaking time is reached, the two electric telescopic rods are extended to drive the seed barrel to rise above the breeding barrel. After the drainage is completed, the seed barrel can be removed from the sleeve.

[0022] As a further improvement to the utility model, an inflatable sealing ring 22 is fixedly installed at the position near the upper end of the inner circumferential wall of the breeding cylinder 1, and an air intake pipe 23 and an exhaust pipe 24 connected to the outside of the breeding cylinder 1 are respectively provided at both ends of the inflatable sealing ring 22, and the inlet pipe 23 is connected to the external air supply device, and an inlet valve 25 and an exhaust valve 26 are respectively installed on the inlet pipe 23 and the exhaust pipe 24, and a sealing groove 27 adapted to the inflatable sealing ring 22 is provided on the cylinder cover 6. When the cylinder cover 6 is matched with the open end of the breeding cylinder 1, the inlet valve is opened to inflate the inflatable sealing ring through the inlet pipe, and the inflatable sealing ring is matched with the sealing groove on the cylinder cover after being inflated and expanded, thereby ensuring the sealing performance of the entire device. When the two electric telescopic rods drive the cylinder cover to move, the exhaust valve 26 can be opened to exhaust and shrink the inflatable sealing ring, thereby avoiding interference of the inflatable sealing ring with the movement of the cylinder cover.
