Description

TECHNICAL FIELD

[0001] The utility model belongs to the artificial pollination auxiliary device, specifically is the jerusalem artichoke crossbreeding auxiliary pollination device. BACKGROUND

[0002] Jerusalem artichoke perennial herb, 1-3 meters tall, has the underground stem of block and fibrous root. The stem is straight, has branch, is covered white short rough hair or bristle. The leaf is usually opposite, has petiole, but the upper leaf is alternate, is ovate or ovate elliptic, has long handle, is 10-16 centimeters long, 3-6 centimeters wide, base wide wedge or round, sometimes slightly heart-shaped, top end gradually thin tip, edge has coarse sawtooth, has tri-furcate pulse from base, short hard hair on the upper leaf vein, lower surface is covered with soft hair. The head-shaped inflorescence is relatively large, few or many, single in branch end, has 1-2 linear needle-shaped bracts, is vertical, 2-5 centimeters in diameter, perianth is multiple, needle-shaped, is 14-17 millimeters long, 2-3 millimeters wide, top end long gradually sharp, back is covered with short down, edge is covered with unfolded edge hair; the receptacle is long circular, is 8 millimeters long, back has rib, upper end is unequal tri-shallow split. The tongue-shaped flower is usually 12-20, tongue piece yellow, unfolds, long elliptic, is 1.7-3 centimeters long, the tubular flower corolla is yellow, is 6 millimeters long. The achene is small, wedge-shaped, has 2-4 hairy conical flat plume on the upper end.

[0003] Among them, when the jerusalem artichoke is crossbred, it needs to be artificially pollinated, and when artificially pollinated, the workers pollinate by hand, and the efficiency is relatively low. In order to improve the artificial pollination speed, the pollen is often injected into the water jug, and then sprayed out with the water jug.

[0004] Among them, since the pollen density is less than the density of water, the pollen floats on the water surface, and the water suction pipe of the water spraying pot is located at the bottom of the water spraying pot, so that when the water is sucked and sprayed, due to the distance problem, only a small amount of pollen is sucked each time, so that a large amount of water and a small amount of pollen are sprayed, which is not conducive to the pollination of the pollen.

[0018] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] The device for assisting pollination in cross breeding of jerusalem artichoke is shown in the figure. It comprises a water spraying kettle, which comprises a kettle body 1, the kettle body 1 is straight-cylindrical, a filter screen 3 is horizontally arranged in the kettle body 1, through holes are formed in the filter screen 3, a water suction pipe 2 of the water spraying kettle passes through the through holes, a feeding hole is further formed in the filter screen 3, a pipe 4 is arranged in the feeding hole, the upper end of the pipe 4 passes out of the kettle body 1 and is in communication with the outside, the pipe 4 is closed by a valve 5, the lower end of the pipe 4 is located below the filter screen 3, and the pipe 4 is sealed at the position where it passes out of the kettle body 1. Figure 1 When the device is used, pollen is conveyed into the kettle body 1 through the pipe 4 and is blocked by the filter screen 3, then water is injected into the water spraying kettle, wherein the pollen is close to the water inlet end of the water suction pipe 2 of the water spraying kettle under the blockage of the filter screen 3, and the water can pass through the filter screen 3, so that more pollen can be sucked into the water suction pipe 2 of the water spraying kettle when the water is sprayed, and then the pollen is sprayed out of the water spraying kettle, thereby facilitating the pollination of the pollen.

[0020] The feeding hole is rotatably connected with the pipe 4 through a bearing, the upper end of the pipe 4 passes out of the kettle body 1, screw holes are formed in the kettle body 1, and external threads are formed in the upper part of the pipe 4 and are matched with the screw holes. The pipe 4 is threadedly connected with the screw holes in the kettle body 1, so that the distance between the lower end of the pipe 4 and the inner wall of the bottom surface of the kettle body 1 can be changed by rotating the pipe 4 under the premise that the pipe 4 and the screw holes are sealed, and then the height of the filter screen 3 is changed, thereby changing the position of the pollen suspended in the water and the suction amount of the pollen.

[0021] The upper end of the pipe 4 is upwardly connected with a feeding nozzle 6 which is wide at the upper end and narrow at the lower end, and the valve 5 is arranged between the feeding nozzle 6 and the kettle body 1. The pollen can be conveniently injected into the pipe 4 through the feeding nozzle 6 and then into the kettle body 1 through the pipe 4.

[0022]

[0023] ​The lower part of the kettle body 1 is provided with a round hole, and a rotating rod 7 is arranged in the round hole. The rotating rod 7 is rotatably connected with the round hole through a sealing bearing. The rotating rod 7 is arranged below the water suction pipe 2 of the water spraying kettle and is vertically provided with a push rod 8. The lower part of the rotating rod 7 is fixedly connected with a rotating handle 10. The bottom surface of the kettle body 1 is fixedly connected with a base 9 around the periphery. The bottom surface of the base 9 is below the plane on which the rotating handle 10 is arranged. The rotating handle 10 is used to rotate the rotating rod 7. The rotation of the rotating rod 7 drives the rotation of the push rod 8. In this way, the water in the kettle body 1 can be disturbed, so that the pollen attached to the inner wall of the kettle body 1 is separated from the inner wall, and then the pollen can be easily sucked out. The base 9 can facilitate the placement of the kettle body 1 on the desktop, and the rotating handle 10 can facilitate the rotation of the rotating rod 7.

[0024] The use of the present application can change the distance of the pollen to the water inlet end of the water suction pipe 2 of the water spraying kettle through the filter screen 3. In this way, more pollen can be sprayed out of the water spraying kettle when the water spraying kettle sprays water, thereby facilitating the pollination of the pollen.

[0025] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
