Description

Technical Field

[0001] The utility model relates to the technical field of crop pollination, in particular to an artificial pollination device special for wheat breeding. Background Art

[0002] In the process of wheat breeding, artificial pollination is a crucial link, which is directly related to the success of wheat variety improvement.

[0003] After searching, the Chinese patent with publication number CN219894163U discloses an artificial pollination device specially used for wheat breeding, including a pollination grip, a pollination device is arranged inside the pollination grip, and a sliding equipment block is arranged inside the pollination grip, so that the position between the operation position and the pollination port can be adjusted according to the user's behavioral habits, which is convenient for the user to use. The internal fixed storage box of the equipment block is used to store pollen, and a sliding blanking block is arranged inside the storage box, and the surface of the blanking block has fixed teeth. The sliding of the blanking block drives the quantitative gear to rotate, and then the quantitative block rotates to drive the pollen to fall into the interior of the air bag in a quantitative manner, thereby achieving the fixed amount of pollen sprayed from the pollination port. Each wheat plant obtains a certain amount of pollen, ensuring that the difference in the growth state of wheat in the later stage is not related to the amount of pollination.

[0004] However, it is necessary to pump air by pressing the airbag, and it is impossible to ensure that the hands do not shake during the pressing process, and the pollen is directly sprinkled on the wheat ears. This method is not only inefficient, but also difficult to ensure the utilization rate and accuracy of the pollen due to the complex structure of the wheat ears; at the same time, the pollination process is easily affected by external environmental factors such as wind and humidity, resulting in a large amount of pollen unable to accurately attach to the pistil, thereby reducing the pollination success rate and the wheat fruit set rate, and causing a large amount of pollen waste. Therefore, the present application provides a special artificial pollination device for wheat breeding to meet the needs. Utility Model Content

For some known technologies, those skilled in the art may also adopt other alternative implementations. Furthermore, the accompanying drawings are provided solely for the purpose of describing the embodiments in greater detail and are not intended to limit the present invention.

[0022] like Figure 1 - Figure 2 As shown, an embodiment of the present invention provides a special artificial pollination device for wheat breeding, including: a machine box 1, which is provided with a storage chamber 7 for storing pollen; a fan 6, which is arranged inside the machine box 1, and the output end of the fan 6 is connected to a feeding channel 10, which is arranged inside the machine box 1 and connected to the outside at one end; a sleeve 4, which is sealed with the feeding channel 10 through a hose 3, and the hose 3 is made of silicone or rubber and can automatically restore after folding. The sleeve 4 has a cylindrical structure and is used to be sleeved on the wheat ears to be pollinated; a conveying mechanism, which is used to convey pollen, and transports the pollen from the storage chamber 7 to the feeding channel 10.

[0023] By setting up a conveying mechanism, a certain amount of pollen is transported from the storage chamber 7 to the feeding channel 10. Under the action of the fan 6, the pollen inside the feeding channel 10 is blown to the inside of the sleeve 4 through the conveying channel 9. The sleeve 4 is sleeved on the outside of the wheat ear to wrap the wheat ear, thereby improving the utilization rate of the sprayed pollen and reducing pollen waste.

[0024] like Figure 1 As shown, it also includes a belt 2, the two ends of which are respectively connected to the side walls of the machine box 1, for looping the machine box 1 around the operator's waist, freeing the operator's hands, and making it easier for the operator to put the sleeve 4 on the wheat ear by operating with both hands.

[0025] like Figure 2 As shown, the conveying mechanism includes: a feed channel 9, which is opened inside the machine box 1 and connects the storage chamber 7 and the feed channel 10; an auger 11, which is rotatably connected to the inside of the feed channel 9, and the auger 11 is slidably connected to the inner wall of the feed channel 9; a motor 12, which is fixed at the bottom of the machine box 1, and the output end of the motor 12 is connected to one end of the auger 11, which is used to drive the auger 11 to rotate.

[0026] The auger 11 is driven by the motor 12 to rotate in the feeding channel 9 , and the pollen in the storage chamber 7 is evenly and continuously transported to the feeding channel 10 under the pushing action of the spiral blades.

[0027] like Figure 2 As shown, it also includes a feeding port 8, which is arranged at the top of the storage cavity 7 and is used to add pollen to the storage cavity 7. A cap is threadedly connected to the feeding port 8 and is used to seal the storage cavity 7 to ensure the sealing and moisture-proof properties of the storage cavity 7 and the quality and activity of the pollen.

[0028] like Figure 2 As shown, it also includes: a wind speed adjustment knob 13, which is set on the top of the machine box 1 and is used to adjust the wind output of the fan 6; a feed adjustment knob 14, which is set on the top of the machine box 1 and is used to adjust the speed of the motor 12.

[0029] Among them, the wind speed adjustment knob 13 and the feed adjustment knob 14 are both electrically connected to the control circuit board, and the control circuit board is electrically connected to the motor 12 and the fan 6, thereby achieving the adjustment of the motor 12 speed and the fan 6 output wind force.

[0030] like Figure 1 As shown, it also includes a start button 5, which is arranged on the outer wall of the sleeve 4 near one end of the hose 3 and is used to control the opening and closing of the fan 6 and the motor 12.

[0031] The start button 5 is also electrically connected to the control circuit board. The connection circuit is buried on the side wall of the hose 3. The motor 12 adopts a stepper motor. A single press of the start button 5 generates a pulse signal. The motor 12 receives the signal and rotates to a rated output angle.

[0032] like Figure 2 As shown, the bottom wall of the storage cavity 7 is inclined, and the lowest end of the bottom wall is located at an end close to the feeding channel 9.

[0033] This arrangement facilitates the movement of pollen in the storage chamber 7 toward one end close to the conveying mechanism, and the shaking or vibration generated when the operator walks further enhances the pollen collection effect.

[0034] The technical solution provided by the present invention is that when artificially pollinating wheat, first, open the cap of the feeding port 8 on the top of the storage chamber 7, add enough pollen into the storage chamber 7, and replace the cap to maintain the sealing and moisture-proof properties, then put the belt 2 loop around the operator's waist to ensure that the machine box 1 is firmly fixed on the operator's abdomen or side waist position for easy operation, and adjust the output wind force of the fan 6 through the wind speed adjustment knob 13 as needed to ensure that the wind force is moderate, which can effectively blow the pollen without causing waste, and adjust the speed of the motor 12 through the feeding adjustment knob 14 to control the amount of pollen delivered in a single time. After starting the operation, hold the sleeve 4 and put it on the outside of the wheat ear to ensure that the sleeve 4. Wrap the wheat ears well and press the start button 5 once. At this time, the motor 12 and the fan 6 are started at the same time. The motor 12 drives the auger 11 to rotate and transports the pollen in the storage chamber 7 to the feeding channel 10. At the same time, the fan 6 blows the pollen in the feeding channel 10 to the wheat ears through the hose 3 and the sleeve 4 to complete the pollination. During this process, the start time of the motor 12 is set at 2s; the start time of the fan 6 is set at 6s. After the pollination of one wheat ear is completed, the sleeve 4 is quickly moved to the next wheat ear, and the above steps are repeated to continue the pollination operation. During the operation, the pollination effect can be optimized by observing the pollination situation of the wheat ears and adjusting the feeding adjustment knob 14 and the wind speed adjustment knob 13.
