Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of corn breeding, and particularly relates to a portable corn field pollen collecting and pollinating device. BACKGROUND

[0002] In the process of corn planting, due to the influence of abnormal natural factors or soil, cultivation techniques, human factors, etc., the phenomenon of mismatched flowering often occurs, especially the father's late phenomenon, and sometimes the flowering is seriously mismatched. Taking conventional control and promotion measures is of no avail. Therefore, we try to use the technology of "off-site male collection-in vitro pollen culture-artificial pollination" to provide a new way to solve the problem of serious mismatched flowering under abnormal conditions.

[0003] At present, the collection of tassel pollen is usually completed by artificial in the corn field. However, since the corn pollen is on the tassel at the top of the corn stalk, and the height of the corn stalk is high, the artificial pollen collection needs to bend the corn stalk first, then cover the tassel with a bag and shake the corn stalk, so that the anther connected by the filament and the pollen wrapped inside the anther on the tassel fall into the bag to complete the pollen collection. However, the interval between the corn stalks in the corn field is small, and the bent tassel of the corn stalk will definitely collide with other corn stalks. The pollen on the tassel will scatter everywhere under the shaking and collision of the corn stalk, which not only causes the waste of corn pollen, but also makes the pollen collection work time-consuming and laborious. In addition, since the collection and pollination of corn pollen in the prior art are generally carried out separately, the collected pollen is first collected, and then a simple corn pollination device is used to pollinate the corn. This pollen collection and pollination mode is low in work efficiency, which greatly affects the efficiency and quality of the pollination work.

[0004] Therefore, it is necessary to design a new corn field pollen collecting and pollinating device to solve the above problems. SUMMARY

[0025] The above-mentioned powdering assembly 9 is used for knocking off the anthers covered with pollen on the tassel of the corn stalk to facilitate the subsequent collection of the pollen, and comprises a cylindrical shell 9-1 fixed on the second top plate 4, the side of the shell 9-1 is provided with an air inlet 9-2, the air inlet 9-2 deviates from the axis of the shell 9-1, the air inlet 9-2 is connected with the air outlet 10-3 through the second exhaust pipe 12, the top of the shell 9-1 is provided with an air outlet 9-3, the axis of the shell 9-1 is penetrated and rotationally provided with a rotating pipe 9-4, the rotating pipe 9-4 penetrates the second top plate 4, the top end of the rotating pipe 9-4 is closed, a plurality of through holes 9-6 are formed on the rotating pipe 9-4 in the shell 9-1, and a plurality of fan blades 9-5 are arranged on the rotating pipe 9-4, a plurality of support rods 9-9 are arranged on the rotating pipe 9-4 below the second top plate 4, the support rods 9-9 are provided with a base body 9-10, a plurality of comb teeth 9-11 for scraping the top end of the tassel of the corn stalk and a cleaning brush 9-12 for cleaning the inner wall of the cover body 1 and the cover body 2 are arranged on the base body 9-10.

[0026] The above-mentioned collecting device 8 is used for collecting the anthers and the pollen falling from the tassel, and comprises a shell 8-1, a partition plate 8-3 is arranged in the shell 8-1, a cyclone separator 8-4 is arranged through the partition plate 8-3, a screen 8-5 is arranged obliquely below the cyclone separator 8-4 in the shell 8-1, a residue discharge port 8-6 is arranged on the side wall of the shell 8-1 corresponding to the lowest part of the screen 8-5, the bottom of the shell 8-1 is provided with the discharge port 8-7, a pull-out type filtering assembly 8-8 is arranged above the cyclone separator 8-4 in the shell 8-1, the top of the shell 8-1 is provided with an exhaust port 8-2, and the airflow inlet of the cyclone separator 8-4 is connected with the exhaust pipe 24.

[0027] Considering that the anthers and the pollen entering the collecting device 8 may not be separated and all fall on the screen 8-5, in order to facilitate the screening of the two, a knocking mechanism corresponding to the shell 8-1 is arranged outside the shell 8-1, the knocking mechanism comprises a support frame 8-9 fixed outside the shell 8-1, a support shaft 8-10 is fixed on the support frame 8-9, a beating plate 8-11 is rotationally arranged on the support shaft 8-10, and a torsional spring 8-12 is arranged on the support shaft 8-10 to force one end of the beating plate 8-11 to be attached to the shell 8-1; the rotating pipe 9-4 is provided with a driving gear 9-8 corresponding to the beating plate 8-11.

[0028] The air flow discharged through the exhaust pipe 11 enters the air inlet 10-2 in the pneumatic assembly 10, and then the piston 10-4 gradually rises, the guide rod also rises, and the rope 13 is pulled to gradually close the top plate two 4 to the top plate one 3. At this time, it needs to be noted that the air flow needs to avoid the top plate one 3 and the top plate two 4 from being attached before being discharged from the exhaust port 10-3, otherwise the guide rod cannot continue to rise, the piston 10-4 cannot rise, the air flow cannot be discharged from the exhaust port 10-3, and the powdering assembly 9 cannot operate. If the air flow can be discharged from the exhaust port 10-3 before the top plate one 3 and the top plate two 4 are attached, if the air pressure at the lower part of the piston 10-4 is not large enough, the piston 10-4 cannot continue to rise. At this time, due to the normal operation of the powdering assembly 9, the knocked off stamens and pollen may fall from the gap between the cover one 1 and the cover two 2, so that the stamens and pollen cannot normally fall to the powder discharge port and enter the collecting device 8 along with the air flow. Therefore, the pre-sealing edge 20 is arranged inside the two sides of the cover one 1 opposite to the cover two 2. When the air flow can be discharged from the exhaust port 10-3 to make the powdering assembly 9 operate, the pre-sealing edge 20 can enter the cover two 2, so as to ensure that the stamens and pollen falling from the tassel can smoothly fall to the vicinity of the powder discharge port and be collected.

[0029] Considering that the air blower 6 is relatively heavy, in order to facilitate carrying, the air blower 6 is arranged on the belt 7 worn by the user.

[0030] It should be noted that in order to facilitate the use of the device, the above-mentioned hand-held rod 15 is a hollow structure, and the battery for supplying power to the entire device is arranged in the hand-held rod 15.

[0031] In order to facilitate the comfort of the operator, the top end of the hand-held rod 15 is hingedly installed on the hinge frame 14, and a plurality of positioning holes 21 are arranged on the hinge frame 14. The top end of the rotating rod is also provided with a through hole 9-6 corresponding to the positioning hole 21, and the top end of the rotating rod is fixed with the hinge frame 14 through the corresponding bolt and nut 22 corresponding to the positioning hole 21.

[0032] The specific working principle of the present application is as follows: in specific use, an operator holds the bottom handle 16 of the hand-held rod 15 with one hand and holds the handle 26-4 of the pollinator 26 with the other hand; when it is needed to collect pollen from a certain corn, the tassel is first placed between the cover body one 1 and the cover body two 2, and then the air blower 6 is started; under the action of the air blower 6, the airflow enters the cyclone separator 8-4 from the exhaust pipe 24, and then the airflow is discharged from the exhaust port 8-2 into the shell 8-1 through the exhaust pipe one 11; the airflow pushes the piston 10-4 to move upward, and the guide rod moves upward accordingly, and the pull rope 13 pulls the top plate one 3 to move close to the top plate two 4; when the pre-sealing edge 20 on the cover body one 1 enters the cover body two 2, the airflow begins to be discharged from the exhaust port 10-3 into the shell 8-1 of the pollen beating assembly 9; the airflow blows on the fan blade 9-5 in the shell 8-1 to make the rotating pipe 9-4 rotate, and then the plurality of comb teeth 9-11 beat or comb the tassel to make the anther and pollen fall off; the airflow in the shell 8-1 finally enters the rotating pipe 9-4 from the through hole 9-6 and is discharged from the bottom end of the rotating pipe 9-4 to blow on the tassel; the fallen anther and pollen enter the pollen discharge port under the action of the airflow, and then enter the collecting device 8 through the air blower 6 and the exhaust pipe 24 and fall on the screen 8-5 in the collecting device 8; at this time, it needs to be noted that the pollen on the screen 8-5 is shaken off by the beating plate 8-11 which is continuously driven by the driving gear 9-8, and finally can be discharged through the discharge port 8-7; then the pollen enters the collecting cylinder 26-1 of the pollinator 26 through the powder outlet pipe 25, and the anther and other impurities are left on the screen 8-5 and finally can be discharged from the residue discharge port 8-6.

[0033] When the pollen collection of a certain tassel is completed, the air blower 6 is turned off, and the piston 10-4 moves downward under the action of the elastic rod 10-7; the top plate two 4 moves away from the top plate one 3 under the action of the elastic telescopic rod 17.

[0034] When it is needed to pollinate a certain corn, the thumb of the hand holding the handle 26-4 presses the pressing rod 26-5 downward to make the mesh plate 26-9 move downward, the sealing needle separates from the powder outlet hole, and the powder outlet hole is opened; then the pollinator 26 is shaken, and the pollen in the collecting cylinder 26-1 is scattered outward to fall on the corn silk to complete the pollination operation.

[0035] 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 preferred embodiments, those skilled in the art should understand that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent ones; without departing from the spirit of the technical solutions of the present application, they should be covered in the technical solution range of the present application.
