Embodiment 1

[0038] A sorghum emasculation forceps, please refer to Figure 1 to Figure 4 .

[0039] Such as figure 1 As shown, the sorghum detasseling forceps provided by the embodiment of the present invention includes an outer layer of forceps 1 and an inner layer of forceps 2 fixed together. The upper splint 11 of the outer layer of forceps 1 and the upper splint 21 of the inner layer of forceps 2 are between the ends Between the first connecting position 31, the lower splint 12 of the outer tweezers 1 and the end of the lower splint 22 of the inner tweezers 2 is the second connecting position 32, and the first connecting position 31 and the second connecting position 32 are welded. Therefore, the outer forceps 1 and the inner forceps 2 can be fixed to each other. In other embodiments, the rear ends of the outer tweezers 1 and the inner tweezers 2 can also be connected by rivets, screws or glued together.

[0040] A control mechanism is provided in the outer tweezers 1 and the inner tweeze...

Embodiment 2

[0051] A sorghum emasculation forceps, please refer to Figure 5 with Image 6 .

[0052] Such as Figure 5 As shown, the outer tweezers 1 of the sorghum detasseling tweezers provided by the embodiment of the present invention includes an outer connecting plate portion 15 located between the ends of the upper splint 11 and the lower splint 12, and the inner tweezers 2 include an upper splint 21 and a lower splint. The inner connecting plate portion 26 between the ends of the splint 22. The outer surface of the tail of the inner tweezers 2 is glued to the inner side of the tail of the outer tweezers 1, and the upper and lower splints 21 and 22 of the inner tweezers 2 are provided with holes at the front ends for connecting the upper and lower hooks of the spring 25.

[0053] The difference from Embodiment 1 is that the joystick of the control mechanism in this embodiment is a pull rod 43 passing through the inner connecting plate portion 26 and the outer connecting plate portion 15....

Embodiment 3

[0056] A sorghum emasculation forceps, please refer to Figure 7 .

[0057] Such as Figure 7 As shown, the difference from Embodiment 2 is that the sorghum emasculating forceps provided by the embodiment of the present invention are provided with first inner protrusions 14 and second inner protrusions 24 on the upper and lower surfaces of the movable head 41. Positioning groove 411 and second positioning groove 412.

[0058] The movable head 41 moves backward while pushing up the first inner protrusion 14 and the second inner protrusion 24. When the first inner protrusion 14 is located in the first positioning groove 411, the second inner protrusion 24 is just at the second In the positioning groove 412, at this time, the outer tweezers and the inner tweezers are simultaneously opened; as the movable head 41 moves backward, the first inner protrusion 14 can enter the second positioning groove 412. At this time, the movable head 41 does not Then push up the second inner protrusion...

Abstract

The invention discloses sorghum castration tweezers which comprise outer-layer tweezers and inner-layer tweezers which are fixed together, wherein tweezers mouths of the inner-layer tweezers are positioned in tweezers mouths of the outer-layer tweezers; and a control mechanism is arranged in the outer-layer tweezers and the inner-layer tweezers so as to enable the tweezers mouths of the outer-layer tweezers and the tweezers mouths of the inner-layer tweezers to be opened or closed freely. After front ends of the tweezers probe into glume shells of sorghum, an operating rod can be controlled toenable the tweezers mouths of the outer-layer tweezers and the tweezers mouths of the inner-layer tweezers to be opened simultaneously to expand the glume shells of the sorghum, and since the glume shells are expanded by the outer-layer tweezers, the glume shells are not closed, so that actions of the inner-layer tweezers can be conveniently observed, anthers are all within a clamping range of the tweezers mouths of the inner-layer tweezers, the anthers in the glume shells can be completely taken out at one time, both the glume shells are prevented from damage and the castration efficiency and quality are improved, and the fruiting rate after pollination can be ensured.

Description

Technical field [0001] The invention relates to the technical field of equipment for breeding, in particular to a sorghum detasseling forceps. Background technique [0002] The emasculation method is a commonly used method in cross breeding, such as in the cross breeding of hermaphroditic crops such as wheat and rice. In manual emasculation, the methods and tools of emasculation are different due to the different floral structure and flowering habits of different crops. For example, legume anthers mature first, so you can remove the anthers when the buds are immature. It is more convenient to emasculate; the flowers of Chrysanthemum are very small and emasculation is more difficult. Generally, the pollen is washed with running water when they just bloom. Drop. [0003] Sorghum is a hermaphroditic crop. The current method of emasculation is to use medical tweezers to open the glume of sorghum, and insert the tip of the tweezers into the glume, and then use the tweezers to clamp of...
