Description

Technical Field

[0001] This utility model relates to the field of millet pollination technology, and in particular to an auxiliary device that can be used for millet pollination. Background Technology

[0002] Millet is a specialty grain crop in northern China and has a long history of cultivation. It is rich in carbohydrates, protein, fat, and various vitamins and minerals, such as B vitamins, iron, magnesium, and zinc—all essential nutrients for the human body. The hulled millet kernels are called millet porridge, which is easily digested and absorbed, making it suitable for people of all ages, especially those with weaker digestive systems, such as the elderly and children.

[0003] Millet pollination mainly relies on natural wind or insect pollination. This method has problems such as uneven pollination and low pollination efficiency. Especially under bad weather conditions, the pollination effect is even more difficult to guarantee. Therefore, manual or mechanical assistance is needed for pollination. However, the anthers and silks of millet are soft, and conventional pollination methods can easily damage the anthers and silks of millet, affecting the pollination effect.

[0004] A Chinese patent document with publication number CN217742651U discloses an auxiliary device for artificial pollination of rice. The auxiliary device includes two rope rods and a rope. The two rope rods have the same structure. Each rope rod includes an inner rod. An outer cylinder and a reel are provided on the outside of the inner rod. The outer cylinder and the reel are rotatably connected to the inner rod. The top end of the reel is fixedly connected to the bottom end of the outer cylinder. The reel is used to wind the rope. A locking mechanism for locking the outer cylinder is installed on the inner rod. Opening the locking mechanism allows the outer cylinder and the reel to be rotated. Closing the locking mechanism can fix the outer cylinder and the reel. This auxiliary device allows for easy adjustment of the rope length between the two guide rods, ensuring that the rope length is sufficient for two workers to each hold a guide rod and walk along the two ridges of the paddy field. It can quickly adjust the rope length between the two guide rods to address situations where the distance between the two ridges in different paddy fields is unequal, thus improving the efficiency of artificial pollination of hybrid rice. However, this auxiliary device for artificial pollination of rice is not suitable for assisting in the pollination of millet. Millet pollen is easily dispersed by wind, and the vibration generated by pulling the rope may not be sufficient to fully disperse the pollen. Furthermore, the stalks and silks of millet are soft, and pulling the rope may damage them, affecting the pollination effect.

[0005] To address the shortcomings of the existing technology, providing an auxiliary device for millet pollination is a worthwhile research topic. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of conventional pollination methods, which are prone to damage to the stalks and silks of millet and affect the pollination effect due to their softness. This invention provides an auxiliary device for millet pollination that achieves the technical effect of not damaging the stalks and silks of millet and being highly efficient.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] An auxiliary device for pollinating millet includes two side support modules, a pollination module between the support modules, several wind power modules on the pollination module, and a movable module at the bottom of each support module.

[0009] The agitation pollination module includes a pull cord and an agitation cloth fixedly connected to the bottom of the pull cord, the length of which is adapted to the length of the pull cord.

[0010] One end of the pull rope is fixedly connected to the top of the support module, and the other end of the pull rope is connected to another support module with a winding assembly. This auxiliary device can efficiently complete the pollination assistance work in large millet fields and improve the millet grain filling rate.

[0011] The winding assembly includes a servo motor fixedly connected to the top of the support assembly and a winding roller fixedly connected to the output end of the servo motor. The height of the winding roller is greater than the width of the tufting fabric. The rotation of the winding roller winds up part of the pull rope and the tufting fabric, thereby controlling the length of the pull rope and the tufting fabric between the two support modules.

[0012] The support module includes a telescopic rod, the telescopic rod's extended length being greater than the height of the millet, and the telescopic rod can adjust its height to adapt to millet of different growth stages.

[0013] The telescopic rod is an electric telescopic rod. An infrared sensor is fixedly connected to the inner top of one side of the telescopic rod. The sensing end of the infrared sensor is horizontally oriented towards the moving cloth, and the height of the sensing end of the infrared sensor is equal to the height of the bottom of the moving cloth.

[0014] The wind power module includes a sleeve fitted onto the pull rope and a fan fixedly connected to both sides of the sleeve.

[0015] The sleeve is slidably connected to the pull rope, and the bottom sides of the sleeve extend downwards. The fan is located at the extension of the sleeve.

[0016] The airflow generated by the fan is downward, and the fan weighs less than 100 grams. During the process of moving the millet with the cloth to assist in pollination, the fan can generate airflow above the millet, which promotes the spread of pollen that falls off after the millet is moved in the air, thereby improving the pollination rate and seed setting rate of the millet.

[0017] The mobile module includes a mobile base fixedly connected to the bottom of the telescopic rod. The front and rear sides of the mobile base are rotatably connected to mobile wheels. The triangularly distributed mobile wheels provide sufficient stability and can move on both sides of the millet field to drive the pull rope and the moving cloth to assist in pollination of the millet.

[0018] Positive and beneficial effects:

[0019] 1. This auxiliary device for millet pollination can efficiently assist in pollination in large millet fields, improve the grain setting rate of millet, and the force exerted by the moving cloth on the millet is less than the force exerted by the pulling rope. With the pulling rope as support, the moving cloth moves the millet to promote pollen dispersal, which can avoid the situation where the soft silks of the millet flower axis come into contact with the pulling rope and cause damage, thus affecting the pollination effect.

[0020] 2. This auxiliary device for millet pollination has a telescopic rod that can be adjusted in height to suit millet of different growth stages, so that the bottom of the agitator can keep in contact with the top of the millet for auxiliary pollination.

[0021] 3. This auxiliary device can be used for millet pollination. The fan can generate airflow above the millet, which promotes the spread of pollen that falls off after the millet is stirred in the air, thereby improving the pollination rate and seed setting rate of the millet.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0031] like Figures 1 to 7 As shown, an auxiliary device for millet pollination includes two side support modules, a pollination module between the support modules, several wind modules on the pollination module, and a movable module at the bottom of each support module.

[0032] like Figures 1 to 2 As shown, the pollination module includes a pull cord 1 and a dispensing cloth 2 fixedly connected to the bottom of the pull cord 1. The length of the dispensing cloth 2 is adapted to the length of the pull cord 1.

[0033] One end of the pull rope 1 is fixedly connected to the top of the support module, and the other end of the pull rope 1 is connected to another support module with a winding assembly. By setting the agitator cloth 2 below the pull rope 1, when it is necessary to assist in pollination of millet, the two ends of the pull rope 1 are pulled forward by the two support modules on both sides of the millet field. At the same time, the lower part of the agitator cloth 2 contacts the top of the millet, thereby agitating the millet and causing the pollen on the millet flower axis and silks to fall into the air and spread, increasing the pollination probability and thus increasing the grain setting rate of millet. This auxiliary device can efficiently complete the pollination assistance work in large millet fields and improve the grain setting rate of millet. Moreover, the force of the agitator cloth 2 on the millet is less than the force of the pull rope. With the pull rope as support, the agitator cloth 2 agitates the millet to promote pollen spread, which can avoid the situation where the soft millet flower axis and silks come into contact with the pull rope and cause damage, affecting the pollination effect.

[0034] Furthermore, the agitator 2 is made of lightweight silk or polyester fiber material, which can further reduce damage to the millet flower stalk and silk during contact.

[0035] like Figures 1 to 2As shown, the winding assembly includes a servo motor 3 fixedly connected to the top of the support assembly and a winding roller 4 fixedly connected to the output end of the servo motor 3. The height of the winding roller 4 is greater than the width of the agitator cloth 2. By setting the servo motor 3 with the winding roller 4 on one end of the support assembly, the rotation of the winding roller 4 can wind up part of the pull rope 1 and the agitator cloth 2, thereby controlling the length of the pull rope 1 and the agitator cloth 2 between the two support modules, and thus adjusting the length of the pull rope 1 and the agitator cloth 2 according to the width of the millet field. Example 2

[0036] like Figures 1 to 5 As shown, the support module includes a telescopic rod 5. The telescopic rod 5 has a telescopic length greater than the height of the millet. By setting the support rod as a telescopic rod 5, it can adjust its height to adapt to millet of different growth stages, so that the bottom of the agitator cloth 2 can keep in contact with the top of the millet for auxiliary pollination.

[0037] like Figures 1 to 5 As shown, the telescopic rod 5 is an electric telescopic rod. An infrared sensor 6 is fixedly connected to the inner top of one side of the telescopic rod 5. The sensing end of the infrared sensor 6 is horizontally facing the agitator cloth 2, and the height of the sensing end of the infrared sensor 6 is equal to the height of the bottom of the agitator cloth 2. By setting the infrared sensor 6 on one side of the telescopic rod 5 and electrically connecting it to the electric telescopic rod, before pollinating the millet, the agitator cloth 2 is first adjusted to a height higher than the top of the millet. Then, the telescopic rod 5 is gradually retracted, causing the agitator cloth 2 and the infrared sensor 6 to gradually descend. When the infrared sensor 6 detects the top of the millet, it sends a command to the telescopic rod 5 to stop descending. At this time, the bottom of the agitator cloth 2 is exactly at the top of the millet, making the height adjustment of the support module more efficient and convenient during the pollination assistance process. Example 3

[0038] like Figures 1 to 7 As shown, the wind power module includes a sleeve 7 that is fitted onto the pull rope 1, and a fan 8 that is fixedly connected to both sides of the sleeve 7.

[0039] The sleeve 7 is slidably connected to the pull rope 1, and the bottom sides of the sleeve 7 extend downwards. The fan 8 is located at the extension of the sleeve 7.

[0040] The airflow generated by the fan 8 is downward. The weight of the fan 8 is less than 100 grams. By setting the sleeve 7 and the fan 8 on the pull rope 1, the fan 8 can generate airflow above the millet during the process of moving the millet with the cloth 2 to assist in pollination. This promotes the spread of pollen that falls off after moving the millet in the air, thereby improving the pollination rate and grain setting rate of the millet.

[0041] Furthermore, the sleeve 7 is slidably connected to the pull rope 1. During the winding process of the winding module winding the pull rope, the position of the sleeve 7 and the fan 8 can be adjusted to avoid fixing them to the pull rope and affecting the winding and normal storage of the device. Setting the fan 8 at a lower position makes it easier to keep the two fans 8 balanced and avoids the fan 8 flipping over during the pollination assistance process, which would affect the pollination. The fan 8 is relatively light, which can reduce the pressure on the two support modules and improve the stability of the device.

[0042] Furthermore, the fan 8 and the sleeve 7 are connected by a damped rotating shaft, which allows the fan 8 to rotate and the direction of the airflow generated can be adjusted as needed to improve the pollination rate. Example 4

[0043] like Figures 1 to 3 As shown, the mobile module includes a mobile seat 9 fixedly connected to the bottom of the telescopic rod 5. The front and rear sides of the mobile seat 9 are rotatably connected with mobile wheels 10. By setting the mobile wheels 10 in a triangular distribution at the bottom of the support module, it has sufficient stability and can move on both sides of the millet field to drive the pull rope 1 and the agitator cloth 2 to move to assist in pollination of the millet.

[0044] Furthermore, a counterweight is provided on the mobile base 9 to increase the weight of the device base, so that the device can remain stable during movement and avoid tilting inward under the tension of the rope. Telescopic rods are provided on both sides of the rear end of the mobile base 9, and the moving wheels 10 are set at the ends of the telescopic rods. The distance between the two rear moving wheels 10 can be controlled by adjusting the length of the telescopic rods. When the paths on both sides of the millet field are narrow, the distance between the two rear moving wheels 10 is shortened; when the paths on both sides of the millet field are wide, the distance between the two rear moving wheels 10 is increased to improve the stability of the mobile module.

[0045] The working principle of this utility model is as follows:

[0046] S1. Control the servo motor 3 to rotate and wind up the pull rope 1 and the moving cloth 2 to match the width of the millet field.

[0047] S2. Before pollinating millet, adjust the agitator cloth 2 to a height higher than the top of the millet, and then gradually retract the telescopic rod 5 to make the agitator cloth 2 and infrared sensor 6 gradually descend. When the infrared sensor 6 detects the top of the millet, it sends a command to the telescopic rod 5 to stop descending. At this time, the bottom of the agitator cloth 2 is just at the top of the millet.

[0048] S3. Push the moving components on both sides to move synchronously, which will drive the pull rope 1 and the agitator cloth 2 to move. The lower part of the agitator cloth 2 will contact the top of the millet, thereby agitating the millet and causing the pollen on the millet flower axis and silk to fall into the air and spread, increasing the pollination probability and thus increasing the grain setting rate of the millet.

[0049] S4. During the process of agitating the millet with the agitating cloth 2 to assist in pollination, the fan 8 can generate airflow above the millet, which promotes the spread of pollen that falls off after agitating the millet in the air, thereby improving the pollination rate and grain setting rate of the millet.
