Description

Technical Field

[0001] The invention belongs to the technical field of corn pollination, and particularly relates to a corn pollination device and method with adjustable pollination amount. Background Art

[0002] Corn pollination is the most critical step in the formation of corn kernels, usually in the summer when the temperature is higher. At this stage, the male tassel of corn will produce pollen, and the filaments of the female ear will absorb the pollen grains, thus completing the pollination process. The success or failure of pollination directly affects the number of kernels and yield of corn. The pollination methods of corn are divided into natural pollination and artificial pollination. Natural pollination is a way of corn pollination. After the kernels on the top of the corn column mature, they will naturally fall and fall on the corn ear, thus completing the pollination process. However, this process may be affected by strong winds or rainy days, resulting in a decrease in pollination density, which in turn affects the yield, so corn pollination operations are carried out in conjunction with artificial pollination.

[0003] Artificial pollination usually involves collecting pollen first and then using a pollinator to collect the pollen. The collected pollen is then placed in the pollinator for artificial pollination.

[0004] The existing artificial pollination of corn is usually completed by relying on the experience of the operators. The pollination amount is not clearly controlled during the pollination process, which affects the corn yield.

[0005] Based on this, a corn pollination device and method with adjustable pollination amount are proposed. Summary of the invention

[0015] As a further description of the present invention, five square through holes are arranged at equal intervals on the connecting rod, and the interval of the square through holes is the same as the interval of the mounting holes on the same diameter line.

[0016] As a further description of the present invention, a semi-circular base is arranged inside the pollen storage cylinder. A transparent scale bar is arranged on the side of the pollen storage cylinder, and a transparent observation window is arranged on the pollination cylinder.

[0020] First, place the collected pollen in the pollen storage tube, and the height of the pollen storage is lower than the height of the communication port. Then, use the horizontal adjustment mechanism to move the pollination mechanism to the upper part inside the pollen storage tube. Next, according to the required pollination amount, adjust the amount of the pollination rod for pollination. When adjusting, rotate the rotating seat to adjust the diameter line of the connecting rod corresponding to the adjustment disk. When the orientation of the connecting rod deviates 5 degrees from the diameter line corresponding to the number of mounting holes on the adjustment disk, stop rotating the rotating seat;

[0021] Then, use the lifting cylinder to lower the connecting rod. When the mounting hole of the connecting rod and the U-shaped connecting seat at the top of the pollination rod are at the same height, stop the lifting cylinder. Then, use the rotating seat to rotate the connecting rod again so that the U-shaped connecting seat is connected in the mounting hole, and the cooperation connection between the pollination rod and the lifting cylinder can be completed;

The pollen scattered during the pollination process falls into the inner cavity of the concave opening and is finally introduced into the collection tube through the communication hole for collection and reuse.

[0026] The present invention has the following advantages compared with the prior art:

[0027] When the present invention is used, first place the collected pollen in the pollen storage cylinder, then use the horizontal adjustment mechanism to move the pollination mechanism to the upper part inside the pollen storage cylinder, and then adjust the amount of the pollination rod for pollination according to the required pollination amount. When adjusting, rotate the rotating seat to adjust the diameter line of the connecting rod corresponding to the adjusting disc. Then, lower the connecting rod by using the lifting cylinder. When the mounting hole of the connecting rod and the U-shaped connecting seat at the top of the pollination rod are at the same height, stop the lifting cylinder. Then, rotate the connecting rod again by using the rotating seat so that the U-shaped connecting seat is connected in the mounting hole, and the cooperation connection between the pollination rod and the lifting cylinder can be completed. Control the lifting cylinder to lower again. Under the external force of the lowering of the lifting cylinder, the pollination rod moves downward away from the retaining ring of the mounting hole until the pollination brush head at the bottom of the pollination rod is immersed in the pollen. Then, control the lifting cylinder to move upward until the pollination brush head with pollen adheres to retracts into the vertical cylinder. Use the horizontal adjustment mechanism to move the pollination mechanism to the upper part inside the pollination cylinder, and then send the corn end to be pollinated into the pollination cylinder through the concave opening. The elastic cloth in the concave opening wraps around the outer periphery of the corn end to be pollinated. The middle of the corn end to be pollinated is aligned with the vertical cylinder.
