Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a pollen extractor used in corn genetic breeding, which effectively solves the problem that the pollen in the tassels will be scattered around under the shaking and collision of corn stalks. Not only will it cause waste of corn pollen, but it will also make the pollen extraction work time-consuming and laborious, and it is easy to break the corn stalk by bending the corn stalk, resulting in loss

Embodiment 1

[0036]Embodiment 1. The present invention is a powder extractor used in corn genetic breeding, including an operating rod 1. The operating rod 1 can be a transparent tube, which is convenient for the operator to observe the situation in the operating rod 1. The operation The bottom of the rod 1 is threadedly connected with the collection tube 01, and the collected pollen can enter the collection tube 01 for storage. It is characterized in that a fixed plate 2 is fixedly installed on the top of the operating rod 1, and the fixed plate 2 can be connected with the operating rod by bolts. 1 is connected, the bottom of the fixed plate 2 is fixedly equipped with a vertical fixed rod 3, and two mutually hinged collection tubes 4 are mounted on the fixed rod 3, and the two collection tubes 4 can be mounted on the fixed rod 3, the two collection tubes 4 are composed of a semi-cylinder 5 with an open bottom and a semi-conical tube 6 that is fixedly connected to the bottom of the semi-cyl...

Embodiment 2

[0037] Embodiment 2, on the basis of Embodiment 1, an opening and closing chute 17 runs through the top of the fixed plate 2 up and down, and an opening and closing slider 18 is slid left and right in the opening and closing chute 17, and the opening and closing The slide block 18 can slide left and right in the opening and closing chute 17, and the tops of the two semi-cylinders 5 are respectively equipped with opening and closing connecting rods 19, and the other ends of the two described opening and closing connecting rods 19 are respectively rotating and equipped with opening and closing connecting rods. On the closing slider 18, when the opening and closing slider 18 slides left and right on the fixed plate 2, the two semi-cylinders 5 can be driven to open or close by two opening and closing connecting rods 19, and the opening and closing slider 18 is connected with the opening and closing An opening and closing extension spring 20 is installed between the chute 17. The op...

Embodiment 3

[0038] Embodiment 3, on the basis of Embodiment 2, a pulley 21 is installed on the right end of the fixed plate 2, and an opening and closing pressure rod 22 is installed on the outer surface of the bottom end of the operating rod 1. The middle part of the rod 22 is rotatably mounted on the operating rod 1, and there is a certain angle between the top and the bottom of the opening and closing pressure rod 22. The opening and closing slider 18 is fixedly connected with an opening and closing pull cord 23, and the opening and closing pull The other end of rope 23 bypasses pulley 21 and is fixed on the top of opening and closing pressure bar 22, presses opening and closing pressure bar 22 during use, and opening and closing pressure bar 22 drives opening and closing slide block 18 to slide rightward by opening and closing pull cord 23, Thereby two described collecting tubes 4 are opened, and when the opening and closing pressure rod 22 is unclamped, the opening and closing slide b...

Abstract

The invention provides a pollen extractor applied to corn genetic breeding. The problems that during manual pollen extracting, not only is corn pollen wasted, but also the pollen extracting work is time-consuming and labor-consuming are solved. The pollen extractor comprises an operating rod, a fixing plate is fixed to the top of the operating rod, two collecting cylinders hinged to each other are rotatably arranged at the bottom of the fixing plate, the side faces of the two collecting cylinders are open, rubber sheets are fixed to the side faces of the two collecting cylinders correspondingly, the bottoms of the two collecting cylinders communicate with collecting feeding pipes correspondingly, the two collecting feeding pipes are sleeved with first collecting pipes correspondingly, and two feeding openings are formed in the side wall of the operating rod; and two feeding sleeves are coaxially and rotationally arranged on the operating rod, the two feeding sleeves communicate with second collecting pipes correspondingly, the two first collecting pipes are slidingly mounted in one of the second collecting pipes, and collecting beating plates are rotatably arranged in the two collecting cylinders correspondingly. Anther can be beaten down and fall to the bottoms of semi-conical cylinders through the collecting beating plates, and pollen in the anther cannot fly to the outside to cause pollen waste.

Description

technical field [0001] The invention relates to the technical field of corn breeding, in particular to a powder extractor used in corn genetic breeding. Background technique [0002] In the process of corn planting, due to abnormal natural factors or the influence of soil, cultivation techniques, human factors and other factors, the phenomenon of flowering failure often occurs, especially the phenomenon that the male parent is late, and sometimes the flowering period is seriously missed. Measures have been of no avail. For this reason, we try to adopt the technology of "external male extraction-pollen in vitro culture-artificial pollination", which provides a new way to solve the problem of severe flowering failure under abnormal circumstances. [0003] At present, the collection of tassel pollen is usually done manually in the corn field, but because the pollen of corn is on the tassel at the top of the corn stalk, and because the height of the corn stalk is relatively high...
