Description

Technical Field

[0001] The present invention specifically relates to an integrated device for harvesting, water and fertilization regulation, and pest control that can be externally connected to a smart agricultural system, and belongs to the technical field of berry picking. Background Art

[0002] Blueberries, along with raspberries, sea buckthorn, blackcurrants, and mulberries, are collectively referred to as small berries. Blueberries, also known as bilberries and blueberry, belong to the family Vaccinium. Vacciniums are perennial deciduous or evergreen shrubs or small bushes with high economic value and broad development prospects. Blueberry consumption in China is expected to grow steadily in the coming years. Currently, fresh blueberries supplied directly to supermarkets can only be harvested manually, with picking costs accounting for approximately 50%-70% of the total production cost. Current mechanical harvesting strategies (pulsed airflow, vibration, and mechanical contact) are completely incapable of safely harvesting blueberries and other small berries. Currently, there is no cost-effective, easy-to-use integrated device for harvesting small berries and regulating water and fertilizer. Summary of the Invention

[0003] In response to market demand, the present invention proposes a blueberry planting and picking integrated facility that uses simulated natural cyclones, chemical conditioning, artificial intelligence and other means. It uses simulated natural cyclones and chemical conditioning and other means to solve the problem of harvesting high-quality blueberries and other small berries, and truly realizes the safe picking of blueberries and other small berries.

[0004] A device for safely harvesting small berries consists of three processing systems: A. a fruit collection base, which includes a mechanical track for fruit size screening, computer color recognition for maturity screening, and a boxing function; B. a cyclone cover, in which a surge pipe directs airflow into the cyclone to detach the fruit using centrifugal force, and an air outlet uses the Rupert principle to blow away light, loose leaves; and C. a control system interface, which uses Internet of Things technology to control airflow, water, fertilizer, and chemical conditioning, thereby controlling the growth and harvest of the berries.

[0005] The structure of this device is divided into two parts, the upper part is a transparent structure, which is a cyclone, namely the cyclone cover, including an air outlet, an air inlet, a cyclone drainage pipe, a cyclone air inlet, a connecting port, and a transparent cyclone. The air outlet and the air inlet are located at the top of the cyclone (cover) shell and are seamlessly inserted into the cyclone (cover) opening. The connecting port connects the air outlet, the air inlet and the transparent cyclone by a simple plug-in method. The air outlet and the air inlet form a 90-degree angle. The cyclone drainage pipe and the cyclone air inlet are located on one side of the transparent cyclone shell, and can be externally connected to a brushless motor of a smart agricultural system.

[0006] The working principle is based on Rupert's principle: the greater the flow rate in the gas, the lower the pressure. The air inlet forms a high-speed airflow under the action of the brushless high-horsepower motor, and a small pressure is formed near the air outlet. Combined with the pressure of the spiral wind in the barrel, light debris will be blown out through the air outlet. The air inlet can be connected to a smart agricultural system, and the data sent back by the sensor is analyzed to control the switch, speed, frequency, etc. of the brushless motor; under the control of the smart agricultural system, the brushless motor drives the blades to encourage the airflow to pass through the cyclone air inlet and introduce it into the cyclone tube drainage pipe to form a cyclonic airflow in the transparent cyclone barrel, so that the fruit is separated from the plant. Under the action of centrifugal force, the fruit rolls along the wall of the barrel. The separation and falling of the fruit can be controlled by controlling the switch, speed and frequency of the brushless motor. The system uses computer vision recognition technology to determine that the blueberries are ripe and then uses cyclonic airflow to intervene to separate the blueberries from the plant. The fruit falls into the packaging box along the barrel wall due to centrifugal force, and lightweight objects such as leaves are discharged from the air outlet due to Rupert's principle.

[0007] The lower half of the device is the fruit collection base, including a connecting groove, a fixed column, large and small screening holes, a fruit sliding blade, a fixed barrel, a water level adjustment liquid input port, a data output port, visual recognition, a bad fruit pusher, a fruit harvesting box, and a sliding blade insertion port; the connecting groove connects the upper cyclone cover and the lower fruit collection seat through a simple plug-in method, and the connecting groove connects the upper cyclone cover and the lower fruit collection seat through a simple plug-in method. The water and fertilizer adjustment liquid input port directly passes through the lower fixed barrel and is inserted into the soil. The internal sensor is connected to the fixed barrel, and an interface with the smart agricultural system is designed on the outside of the barrel wall to transmit the growth data of the plants in the barrel; the visual recognition camera is installed at one end of the fruit outlet of the fixed barrel. It visually recognizes whether the fruit is ripe, transmits a signal to the bad fruit pusher to drive the bad fruit pusher at the other end of the fruit outlet to push out the bad fruit, and the ripe fresh fruit slides into the collection box; the slide blade is inserted into the socket of the fixed barrel wall, and the other end is inserted into the fixed column.

[0008] The working principle is as follows: the fixed column is used to fix the inner end of the blade where the fruit slides off and the large and small screening holes, the fixed barrel is used to fix the outer end of the blade where the fruit slides off, and the water level adjustment liquid input port inputs liquid used to control plant growth under the control of the smart agriculture system; the data output port is used to output various data of the plants in the barrel to the smart agriculture control system, visual recognition is used to identify the maturity of the fruit and control the bad fruit removal rod to remove the bad fruit, and the fruit harvesting box is used to store the fruit.

[0009] The fruits that fall along the tube wall and other debris are selected, identified and separated along the track. Finally, the mature fruits that meet the standards are sent to packaging boxes and directly supplied to supermarkets, restaurants and other places, ensuring the safe harvest of blueberries.

[0010] The control system is the aforementioned smart agriculture system, which utilizes modern information technology and the Internet of Things (IoT) to transform agricultural production into an intelligent, efficient, and precise system. It primarily includes components such as the Agricultural Internet of Things (IoT), smart devices, and data processing and analysis. Through intelligent management of the entire agricultural production process, it enables real-time monitoring, data analysis, and decision support for agricultural production. Currently, this system is widely used in blueberry production, and this invention can be directly connected to the smart agriculture system to achieve blueberry production. Furthermore, this invention eliminates the need for greenhouses, significantly reducing production costs and enabling all greenhouse production functions. IoT controls the environment within the facility, including water, temperature, humidity, fertilizers, hormones, and other blueberry growth conditions. This system controls the entire lifecycle of blueberry growth, maturation, and harvest, including an outlet air speed controller, an inlet air speed controller, temperature and humidity sensors, a soil environment detector, and the flow of water and fertilizer adjustment fluids into and out of the soil.

[0011] Beneficial effects

[0012] This device features a lightweight debris outlet with a simple, efficient, and low-cost structure, utilizing the Rupert principle to blow away light debris. The brushless ducted fan outlet connects to an external smart greenhouse control center, a technology currently widely used in blueberry cultivation, and can be implemented with an open interface. The cyclone drainage pipe rotates the inlet air, creating a cyclone and generating centrifugal force to release the fruit. This overcomes the limitation of contact pickers, which only allow fruit to be harvested for jam production, and addresses the difficulty of vibrating pickers in collecting fruit.
