Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and specifically relates to a cotton topping device and method based on microwave technology. Background Technology

[0002] Currently, cotton topping in my country is mainly carried out manually or with chemical agents. Manual topping is labor-intensive and costly, and its effectiveness varies greatly depending on the cotton farmers' experience. Chemical topping requires multiple sprayings, resulting in numerous operations, and the chemicals are difficult to degrade, posing environmental pollution problems. Summary of the Invention

[0003] This invention provides a cotton topping device and method based on microwave technology to solve the problems mentioned in the background art.

[0004] The present invention provides the following technical solution: a cotton topping device based on microwave technology, characterized in that: it includes an identification controller (1), a microwave emitting mechanism (2), a swinging mechanism (3), and a cover (4), wherein the identification controller (1) is disposed on the upper part of the cover (4), the microwave emitting mechanism (2) is disposed on one side of the cover (4), and the swinging mechanism (3) is disposed on the other side of the cover (4); The microwave transmitting mechanism (2) includes a magnetron (2-1) and a transmitting antenna (2-2). The magnetron (2-1) is fixedly connected to the housing (4). The transmitting antenna (2-2) is fixed on the magnetron (2-1) and extends into the housing (4). The magnetron (2-1) generates microwaves of a higher frequency and transmits them through the transmitting antenna (2-2). The microwaves oscillate rapidly inside the housing (4). The electromagnetic field generated causes the polar electrons of water molecules in the cotton tip to oscillate. The kinetic energy and friction between molecules generate a large amount of heat, which raises the temperature of the cotton tip, causing the cytoplasm structure to be destroyed and transformed into an irreversible condensed state, losing its growth activity. The swing mechanism (3) includes a side plate (3-1), a shelf plate (3-2), a swing shaft (3-3), and a motor (3-4). The side plate (3-1) is located on both sides of the shelf plate (3-2). The swing shaft (3-3) is fixedly connected to the side plate (3-1). The power output shaft of the motor (3-4) is fixedly connected to the swing shaft (3-3). The motor (3-4) is fixedly connected to the cover (4). The shelf plate (3-2) is located outside the transmitting antenna (2-2). The shelf plate (3-2) of the swing mechanism (3) can reflect and gather the electromagnetic waves transmitted from the magnetron (2-1) to the cover (4), making the polar electrons at the tip of the cotton to be beaten oscillate more frequently and the heating speed faster. The cover (4) includes a metal plate (4-1) and a metal mesh (4-2). The metal plate (4-1) forms the five sides of the cover (4) except for the bottom surface, and the metal mesh (4-2) is installed on the bottom surface of the cover (4).

[0005] The present invention also provides a method for applying the aforementioned microwave-based cotton topping device, the steps of which are as follows: S1: The cover (4) descends to the preset height, and the cotton tip passes through the gap of the metal mesh (4-2) and extends into the interior of the cover (4); S2: The identification controller (1) scans the inside of the cover (4), determines the position of the cotton tip on the metal mesh (4-2), and starts the microwave emitting mechanism (2). S3: The swing mechanism (3) receives the control signal from the identification controller (1), controls the opening direction of the shelf (3-2), aligns with the top of the cotton to be hit, and heats up to remove the top of the cotton; S4: Lift the cover (4) to complete the cotton topping operation.

[0006] Compared with existing technologies, this invention converts electrical energy into ultra-high frequency electromagnetic waves. Under the action of this electric and magnetic field, the water and other polar molecules in the cotton bud rotate and rub against each other, generating heat, which eventually burns and deteriorates the bud. This invention does not use chemical agents, has no environmental pollution problems, and has lower labor costs. Attached Figure Description

[0008] The present invention will now be described in further detail with reference to the accompanying drawings: like Figure 1 As shown, a cotton topping device based on microwave technology is characterized in that it includes an identification controller (1), a microwave emitting mechanism (2), a swinging mechanism (3), and a cover (4). The identification controller (1) is located on the upper part of the cover (4), the microwave emitting mechanism (2) is located on one side of the cover (4), and the swinging mechanism (3) is located on the other side of the cover (4).

[0009] like Figure 2 As shown, the microwave transmitting mechanism (2) includes a magnetron (2-1) and a transmitting antenna (2-2). The magnetron (2-1) is fixedly connected to the housing (4), and the transmitting antenna (2-2) is fixed on the magnetron (2-1). The transmitting antenna (2-2) extends into the housing (4). The magnetron (2-1) generates microwaves of a higher frequency, which are emitted by the transmitting antenna (2-2). The microwaves oscillate rapidly inside the housing (4), and the electromagnetic field generated drives the polar electrons of water molecules in the cotton tip to oscillate. The kinetic energy and friction between molecules generate a large amount of heat, which raises the temperature of the cotton tip, thereby destroying the cytoplasmic structure and transforming it into an irreversible condensed state, losing its growth activity.

[0010] like Figure 3 As shown, the swing mechanism (3) includes a side plate (3-1), a shelf plate (3-2), a swing shaft (3-3), and a motor (3-4).

The shelf plate (3-2) is set outside the transmitting antenna (2-2). The shelf plate (3-2) of the swing mechanism (3) can reflect and gather the electromagnetic waves transmitted from the magnetron (2-1) to the cover (4), so that the polar electrons at the tip of the cotton to be beaten oscillate more frequently and the heating speed is faster.

[0011] like Figure 4 As shown, the cover (4) includes a metal plate (4-1) and a metal mesh (4-2). The metal plate (4-1) forms the five sides of the cover (4) except for the bottom surface, and the metal mesh (4-2) is installed on the bottom surface of the cover (4).

[0012] The motor (3-4) listed in this invention can provide driving force for the swing mechanism (3). The motor (3-4) can also be replaced by a hydraulic motor, gear transmission, etc. The way the shelf (3-2) in the swing mechanism (3) gathers microwaves is only one feasible solution. Other materials that can reflect microwaves can also be used to achieve the function. The cover (4) is set as a hexahedral structure, which is only one feasible solution. Other shapes can also be used, which will not be exhaustively listed here.

[0013] The present invention also provides a method for applying the aforementioned microwave-based cotton topping device, the steps of which are as follows: S1: The cover (4) descends to the preset height, and the cotton tip passes through the gap of the metal mesh (4-2) and extends into the interior of the cover (4); S2: The identification controller (1) scans the inside of the cover (4), determines the position of the cotton tip on the metal mesh (4-2), and starts the microwave emitting mechanism (2). S3: The swing mechanism (3) receives the control signal from the identification controller (1), controls the opening direction of the shelf (3-2), aligns with the top of the cotton to be hit, and heats up to remove the top of the cotton; S4: Lift the cover (4) to complete the cotton topping operation.

For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively describe all implementation methods here.
