Description

Technical Field

[0001] The utility model belongs to the technical field of wheat seed selection, in particular to a seed selection device for wheat breeding. Background Art

[0002] The quality of wheat seeds directly affects the yield of wheat, so wheat seed selection is particularly important. Varieties should be selected according to local natural and cultivation conditions, so that good varieties are suitable, good methods are matched, and good varieties and good methods are promoted together.

[0003] Breeding is the art of creating new, superior plant and animal varieties by creating genetic variation and improving genetic traits. Wheat breeding begins with seed selection, a commonly used method currently used. Saltwater selection involves placing seeds in a concentration of saltwater, leveraging buoyancy to separate good from bad seeds. Saltwater, with its greater buoyancy than freshwater, can lift underfilled seeds. However, existing seed selection equipment makes it difficult to remove debris from the upper layer, requiring manual salvaging, which is labor-intensive.

[0004] Therefore, a seed selection device for wheat breeding is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 to 4 As shown, this embodiment provides a seed selection device for wheat breeding, comprising:

[0027] The outer tube 1 and the inner tube 2 are provided with a mounting bracket 3 fixedly connected to the circumferential side of the inner tube 2. The top of the mounting bracket 3 extends outward and overlaps the top surface of the outer tube 1, so that the inner tube 2 is suspended inside the outer tube 1, and the top surface of the inner tube 2 is lower than the top surface of the outer tube 1. A drainage port 4 is provided at the bottom of the outer tube 1.

[0028] A water pipe 5 is connected to a water pump 6 and is used to inject water into the inner tube 2;

[0029] The stirring mechanism is arranged on the side of the outer tube 1 , and the stirring end of the stirring mechanism can extend into the interior of the inner tube 2 .

[0030] The inner tube 2 is used to hold wheat seeds waiting for seed selection. The mounting frame 3 is firmly overlapped on the top surface of the outer tube 1 so that the inner tube 2 is suspended inside the inner tube 2. The top surface of the inner tube 2 is lower than the top surface of the outer tube 1. After placement, salt water of appropriate concentration is added into the inner tube 2. The salt water will float the light bad seeds and make the bad seeds float on the water surface. The stirring mechanism can stir the wheat seeds in the inner tube 2 so that the wheat seeds located inside also have a chance to be located at the top after being stirred, which is convenient for the bad seeds to float to the surface, thereby increasing the seed selection speed and seed selection quality. After stirring for a period of time, the bad seeds and bran and other impurities are all located at the top of the salt water. At this time, the water outlet end of the water pipe 5 can be placed below the surface impurities in the inner tube 2, and the water inlet end is connected to the external salt water. By continuously adding salt water, the bad seeds and impurities on the water surface of the inner tube 2 overflow with the salt water and flow into the outer tube 1, thereby achieving the purpose of separating impurities. This method is convenient and fast, saves manpower, and the salt water overflowing from the outer tube 1 can be filtered and reused, which is relatively water-saving.

[0031] To further optimize the solution, the bottom of the mounting frame 3 is fixedly connected to the outer wall of the inner tube 2 , and the top end extends outward and is fixedly connected to two clamping plates 7 , with a gap provided between the two clamping plates 7 , and the top surface of the outer tube 1 is clamped between the two clamping plates 7 .

[0032] The gaps between the clamping plates 7 match the shape of the side walls of the outer cylinder 1 , and the side walls of the outer cylinder 1 can be firmly clamped in the gaps between the clamping plates 7 .

[0033] A further optimized solution is provided, in which the stirring mechanism includes a hydraulic telescopic rod 8, which is arranged on one side of the outer cylinder 1. A steering motor 9 is fixedly connected to the top of the telescopic rod, and a first extension rod 10 is fixedly connected to one side of the steering motor 9. A stirring motor 11 is fixedly connected to the outer end of the first extension rod 10. The output end of the stirring motor 11 faces downward and is fixedly connected to a rotating shaft 12, and a stirring blade 13 is fixedly connected to the outside of the rotating shaft 12.

[0034] The steering motor 9 is rotatable. When stirring is required, the stirring motor 11 and the stirring blade 13 are rotated to the top surface of the inner cylinder 2 and then the hydraulic telescopic rod 8 is retracted, so that the stirring blade 13 can be extended into the inner cylinder 2 to stir the wheat seeds therein. After stirring is completed, the reverse operation can be performed to move the stirring motor 11 and the stirring blade 13 away from the top surface of the inner cylinder 2, thereby facilitating the disassembly and installation of the inner cylinder 2.

[0035] In a further optimized solution, the stirring blade 13 is a spiral blade.

[0036] The spiral blades facilitate the transfer of the wheat seeds at the bottom of the inner cylinder 2 upwards, making it easier for bad seeds in the wheat seeds to float up.

[0037] To further optimize the solution, a second extension rod 14 is fixed to one end of the outer side of the steering motor 9 away from the first extension rod 10, a lifting rope 15 is fixed to the outer end of the second extension rod 14, a lifting hook 16 is fixed to the tail end of the lifting rope 15, and a lifting ring 17 is fixed to the top of the mounting frame 3, and the lifting hook 16 and the lifting ring 17 are detachably connected.

[0038] The hook 16 is hung on the lifting ring 17. By coordinating the contraction and expansion of the hydraulic telescopic rod 8 and the steering of the steering motor 9, the inner cylinder 2 can be lifted away from the outer cylinder 1 or the inner cylinder 2 can be lifted on the top surface of the outer cylinder 1.

[0039] According to a further optimized solution, a filter screen 18 is detachably connected to the bottom of the outer cylinder 1 , a lap ring 19 is fixed to the bottom of the outer cylinder 1 , and the filter screen 18 is lapped on the lap ring 19 .

[0040] The filter screen 18 can filter the overflowed salt water with impurities, and the filter screen 18 can be easily removed from the top of the outer tube 1 for cleaning and replacement by overlapping the overlapping ring 19.

[0041] To further optimize the solution, the water inlet end of the water pipe 5 is connected to the drain outlet 4.

[0042] The filtered brine is stored in the outer tube 1 and can be directly discharged through the drain port 4 or re-entered into the inner tube 2 through the water pipe 5 for recycling, thereby saving brine and reducing costs.
