Description

artificial pollination device

technical field

The invention relates to a device for artificially pollinating flowers.

Background technique

Artificial pollination refers to the technical measures of artificially transferring plant pollen to the stigma to increase the fruit setting rate. In agricultural production, artificial pollination is often required for crops that lack self-flowering, monoecious plants with different flowers, and dioecious plants when there is a lack of pollinated plants or the climate is bad during the flowering period, which affects normal natural pollination. For example, kiwi fruit and Luo Han Guo must be planted in a reasonable layout and collocation between male and female plants in field cultivation. While effectively using the land area, it is also conducive to the pollination of female flowers in female plants, so as to promote agricultural production and increase efficiency. However, since the natural pollination rate of these plants is very low, artificial assisted pollination is generally required.

However, in actual operation, farmers mostly pollinate manually, which consumes a lot of labor, time and effort, and requires high investment. It is difficult to raise the pollination rate to a high level, and it is easy to cause damage to male and female flowers and affect the harvest. Although there are many types of artificial pollination devices at present, they also have the defects of low degree of automation, large damage to flowers and pollen, and low pollination rate, so the existing technology cannot meet the requirements of modern agricultural production.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an artificial pollination device with simple structure, high degree of automation, little damage to flowers and pollen and high pollination rate.

In order to overcome the deficiencies in the prior art, the present invention takes the following technical solutions:

An artificial pollination device, including a filter core and a filter cover, is characterized in that: the filter core is detachably installed on the filter cover; the filter cover is connected to a hose, and the hose is connected to a three-way cock valve, and one end of the three-way cock valve passes through a venturi The injector is connected to the cyclone separator, and the Venturi injector has a pipeline connected to the upper water bottle, and the pipeline is provided with a water-stop clamp; the top of the cyclone separator is connected to the suction end, and the bottom is connected to the pollen water container through the filter screen, and the pollen water container has a pipeline It is connected to another Venturi injector below, and the pipe is provided with a water stop clamp; one end of the other Venturi injector is connected to the three-way cock valve through the pollen delivery pipe, and the other end is connected to the blowing end through the air delivery pipe.

The suction end and the blowing end are connected to an axial flow fan composed of an axial flow fan casing, a series axial flow booster fan, an exhaust valve, an intake valve and a power, and the axial flow fan realizes two kinds of air blowing and air suction. It is beneficial to reduce equipment investment, make the pollination device more portable, and reduce the labor intensity when the pollination device is used.

The cyclone separator and the pollen water container are threaded, which can not only realize the sealed connection of the two, but also facilitate disassembly. Because the flowering period of male flowers of many plants is earlier than that of female flowers, the detachable function is particularly important. This device can collect male pollen in the pollen water container when the male flowers are open, and then disassemble the pollen water container and store it in the refrigerator. Pollination occurs when the female flowers are open.

The filter cover is connected with the hose through a joint, which is convenient for disassembly and transportation of pollen.

The filter cover is connected with a handle bar, which is convenient for pollination and pollen collection operations.

This design is based on scientific and technological innovation to serve agriculture, rural areas, and farmers. It provides an efficient artificial assisted pollination device, which uses pneumatic negative pressure to collect male flower pollen and separates it with a wet cyclone. At the same time, it can be switched conveniently, and the female flower can be sprayed for pollination.

When the device is working, the power drives the serial axial flow booster fan to rotate at high speed in the axial flow fan casing. When the exhaust valve and the intake valve are opened, the air can be sucked in by the intake valve and discharged by the exhaust valve. The power can be driven by a battery. The motor can also be driven by a micro gasoline engine as required, and the fan blades are connected in series in multiple stages to obtain higher air pressure and air flow.

When it is necessary to collect pollen, fill the water bottle with water and control the opening of the water-stop clamp to be appropriate. The water bottle can be equipped with an air intake hole to supplement the air to enter to avoid poor water flow. The three-way cock valve (powder collection state) connects the hose and the Venturi injector, opens the exhaust valve, slightly opens the intake valve, and starts the power to collect pollen.

The hand lever is convenient to control the filter cover to get close to the male flowers. The filter cover is a coarse mesh filter with a filter core inside. The filter core can pass the pollen smoothly but retain other larger impurities. The filter cover can be quickly opened and locked, and is assembled with the filter element like a light bulb, which is convenient for cleaning and replacing the filter element.

The diversion section of the airflow carrying pollen is appropriately reduced in the Venturi injector to increase the airflow velocity and generate a slight negative pressure, so that the water in the water bottle enters evenly according to the required flow rate under the joint control of gravity, negative pressure and water-stop clamp The Venturi injector mixes with the pollen airflow, and then enters the cyclone separator through the central tube, and is sucked and pumped. Due to the different centrifugal characteristics of the water, pollen and airflow in the cyclone separator, the water and pollen are centrifugally thrown to the wall of the cyclone and are adhered with the water. Downstream through the filter, the impurities are trapped, the pollen and water are separated from the air and temporarily stored in the pollen water container, the pollen water container and the cyclone separator are quickly connected through threads, and when the required negative pressure and suction flow are small, it can be slightly Open the intake valve to adjust.

When pollination is required, open the filter cover and remove the filter element, close the exhaust valve and open the intake valve properly, the three-way cock valve conversion is to connect the pollen delivery pipe and hose, open the water stop clip appropriately, and open the power and Intake valve, the inhaled air is pressurized and enters the Venturi injector at high speed through the air delivery pipe. The diversion section in the Venturi injector is appropriately reduced to increase the air velocity. Under the common control of gravity, micro-negative pressure and water stop clamp, the mixture of pollen and water enters into the required flow evenly and mixes with the air flow evenly, enters the hose through the pollen delivery pipe and three-way cock valve, and passes through the joint from the filter The hood mist is sprayed on the female flowers for efficient pollination.

Compared with prior art, the beneficial effect of the present invention also lies in:

The system is simple, low cost, easy to implement, and has a low failure rate; airflow collects male flower pollen, mist spray has high pollination efficiency for female flowers, and labor efficiency is greatly improved; soft contact does not damage plants, and can be repeated for multiple pollination and pollination operations The best effect is guaranteed, and nutrients can also be conveniently added for co-spraying; low energy consumption, compact equipment, clever application of Venturi injection principle, and broad application prospects.
