TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to a micro pollen collecting device. BACKGROUND

[0002] In the process of agricultural production, artificial pollination can effectively solve the reproductive obstacles such as self-incompatibility of plants and non-meeting of parental flowering period in distant hybridization, and improve crop yield. The rapid and effective collection and storage of pollen during the process of artificial pollination is particularly important. However, most introduced plants lack natural pollination media, and some have reproductive characteristics such as self-incompatibility, so the natural seed setting rate is extremely low, and artificial pollination is needed to improve yield. However, the pollen is small and trace, and it is difficult to collect, which greatly affects the efficiency of artificial pollination. The difficulty in collecting pollen also hinders the progress of related researches on reproductive physiology and breeding.

[0003] Traditional pollen collection technology is rough, which simply squeezes and dries the pistil to collect, the process has high instability, causes great damage to the pollen, and has low collection efficiency, and is only suitable for varieties with large and numerous pollen particles. Through innovation and improvement, the existing technology can collect pollen through vibration, stirring, negative pressure air suction and other methods. However, these methods have many impurities in the collected pollen, are easy to cause mechanical damage to the pollen, and can only collect large and numerous pollen, and cannot collect small and trace pollen. In addition, since the sizes of pollen of different plants are different, the existing technology can only meet the demand of collecting pollen of specific species. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a micro pollen collecting device, which solves the problems of traditional pollen collection technology, such as high instability in the process, great damage to the pollen, low collection efficiency, and being only suitable for varieties with large and numerous pollen particles.

[0005] To achieve the above purpose, the present application is realized by the following technical scheme: a micro pollen collecting device, comprising: A gas generating unit for generating clean gas for blowing pollen; A pulse airflow electronic control unit connected with the output end of the gas generating unit, for adjusting the clean gas into a pulse airflow with specific blowing time and interval time; A pollen collecting unit connected with the output end of the pulse airflow electronic control unit, for collecting the pollen generated after the pulse airflow blows the anther; A gas delivery pipeline for connecting the gas generating unit, the pulse airflow electronic control unit and the pollen collecting unit; A fixer for fixing the gas generating unit, the pulse airflow electronic control unit and the pollen collecting unit.

[0006] Preferably, the gas generating unit comprises: a diaphragm pump as a clean air supply device; a gas tank provided with a gas tank inlet and a gas tank outlet, for storing gas and ensuring stable supply of pulse gas; a pressure relief valve and a pressure gauge provided on the gas tank, for controlling and maintaining stable system pressure.

[0007] Preferably, the pulse gas flow electronic control unit comprises at least one gas channel, each gas channel being provided with: a pulse controller input and a pulse controller output; a solenoid valve for controlling the opening and closing of pulse gas; a time controller electrically connected to the solenoid valve, the time controller being provided with a display and an adjustment button, for accurately controlling the opening and closing time and interval time of the solenoid valve.

[0008] Preferably, the pollen collecting unit comprises: a stamen clamp for separating petals from stamens; a pollen collector; a pollen collection bottle connected to the lower end of the pollen collector; a cannula applicator, one end of the cannula applicator being connected to the pulse gas flow electronic control unit through a blowing tube; a needle-shaped gas outlet connected to the other end of the cannula applicator and placed in the pollen collector, for blowing anther.

[0009] Preferably, the needle-shaped gas outlet is a replaceable needle-shaped gas outlet of different shapes, including at least one of a weak pressure needle-shaped gas outlet, a duckbill needle-shaped gas outlet, a multi-hole needle-shaped gas outlet, and a strong pressure needle-shaped gas outlet, for adjusting the blowing strength of pulse gas flow.

[0010] Preferably, the connecting open end of the pollen collector is provided with a beveled bayonet; the pollen collection bottle is detachably connected to the pollen collector through a pollen collection bottle fixing screw.

[0011] Preferably, the pollen collecting unit further comprises a fixing buckle, the cannula applicator is fixed through the fixing buckle, and the position height of the cannula applicator is adjustable to adapt to stamens of different sizes.

[0012] Preferably, one end of the blowing tube is connected to the pulse controller output, and the other end of the blowing tube is connected to the cannula applicator, for transporting pulse gas.

[0013] Preferably, the gas delivery pipeline and the part in contact with gas are made of polytetrafluoroethylene, silicone, stainless steel, or glass.

[0014] Preferably, the fixer fixes the gas generating unit, the pulse air flow electronic control unit and the pollen collecting unit together, facilitating carrying and operation.

[0015] Working principle: first, after the device is started, the micro diaphragm pump in the gas generating unit starts to work, extracts and compresses clean air, and sends it to the gas storage tank for storage and pressure stabilization, to ensure the stability and purity of the subsequent gas supply. Then, the stable airflow is delivered to the pulse air flow electronic control unit, and the electromagnetic valve in the unit opens and closes at a high frequency under the instruction of the time controller (accurate to milliseconds), thereby converting the continuous airflow into a pulse airflow with a specific blowing time and interval. Finally, the operator selects and installs a suitable needle-shaped air outlet (such as weak pressure, strong pressure, duckbill type, etc.) for the pollen collecting unit according to the quality, volume and adhesion of different pollens, and aligns the plant pistil with the air outlet; the precisely controlled pulse airflow is sprayed from the needle-shaped air outlet, so that the tiny and trace amount of pollen is blown off the anther without mechanical damage, and falls directly into the pollen collecting bottle below under the action of gravity, thereby realizing the non-destructive, efficient and accurate collection of tiny pollen. With its multi-channel design, it can also simultaneously collect different types or multiple targets independently, further improving work efficiency.

[0016] The present application provides a tiny pollen collecting device. It has the following advantages: 1.

Different specifications of needle-shaped air outlets are selected to adjust the pulse airflow strength, so that the same type or different types of tiny and trace amount of pollen can be collected simultaneously. Moreover, the pulse airflow flow rate, interval time and blowing strength of different channels can be adjusted independently, so that the same type and different types of tiny and trace amount of pollen can be collected simultaneously, efficiently and with high compatibility.

[0018] 3. The present application collects pollen by blowing, which can avoid direct manual operation, effectively prevent human damage to pollen structure, and avoid impurities entering the sample, thereby saving time and labor for post-picking pollen collection.

[0019] 4. The present application uses micro components, soft tube connection and fixer buckle fixation, which can be placed in a storage box, facilitating carrying, and meeting the needs of outdoor collection.

[0020] 5、The invention has high collection efficiency, and different quality and volume of micro and trace pollen can be completely collected by blowing, avoiding waste. BRIEF DESCRIPTION OF DRAWINGS
