[0024] Further, the second protection structure 3 includes a horizontal plate 301, the left side of the protective cover 207 is fixedly installed with the horizontal plate 301, the inside of the horizontal plate 301 is rotatably connected with a bidirectional screw rod 302, the back of the horizontal plate 301 is fixedly installed with a second motor 303, the outer surface of the bidirectional screw rod 302 is threadedly connected with a hinged rod 304, the left side of the hinged rod 304 is fixedly installed with a moving plate 305, and the left side of the moving plate 305 is fixedly installed with a protective rod 306.

[0025] Specifically, as shown in the figure, Figure 3 opening the first motor 204 drives one of the belt pulleys 202 to rotate, and then drives the other belt pulley 202 and the threaded rod 201 to rotate through belt transmission, the threaded rod 201 is driven to move up and down through rotation, so as to adjust the distance between the protective cover 207 and the cutter and the crop, prevent the crop from being wound on the cutter through the protective cover 207, ensure the movement of the protective cover 207 to be in a horizontal state through the setting of the T-shaped block and the sliding groove, then pour clean water or insecticide into the inside of the liquid storage chamber through one of the valve pipes, and open the submersible pump 206 to pump out the clean water or insecticide and send it into the inside of the water spraying pipe 209 for spraying, for the purpose of dust prevention or insect killing, and the first motor 204 is arranged to drive the stirring rod 205 to rotate, so as to uniformly stir the insecticide, so as to achieve the protection effect, and facilitate the purpose of dust prevention or insect killing.

[0026] Specifically, as shown in the figure, Figure 4 opening the second motor 303 drives the bidirectional screw rod 302 to rotate, drives the two hinged rods 304 to move through the rotation of the bidirectional screw rod 302, drives the moving plate 305 to move along the sliding rod through the movement of the two hinged rods 304, the sliding rod is arranged to ensure that the moving plate 305 moves along the horizontal state, so as to adjust the position between the protective rod 306 and the protective cover 207, enhance the protection effect, and achieve the purpose of improving the safety of the device.

[0027] Specifically, as shown in the figure, Figure 2As shown, the first motor 204 is a dual-output motor, also known as a dual-output shaft motor or dual-shaft motor. It is a type of motor with two output shafts. This type of motor is usually composed of two independent output shafts, a drive shaft, and a control unit. Each output shaft can work independently or in concert to adapt to different mechanical and power requirements.

[0028] Specifically, such as Figure 2 As shown, the second motor 303 is a forward and reverse motor. A forward and reverse motor is a motor that can achieve forward and reverse rotation. The working principle of a forward and reverse motor is based on changing the phase sequence of the motor power supply to change the direction of rotation. In a three-phase asynchronous motor, the direction of rotation of the motor can be changed by swapping any two phases. This operation is called commutation, which allows the motor to run in different directions as needed.

[0029] When implementing this procedure, please follow these steps:

[0030] 1) First, turn on the first motor 204, and then control the distance between the protective cover 207 and the cutter through the threaded rod 201;

[0031] 2) Then, water or insecticide can be pumped out using submersible pump 206 for dust control or insecticidal purposes;

[0032] 3) The distance between the protective rod 306 and the protective cover 207 is adjusted by setting the second protective structure 3.

[0033] In summary, this harvester cutter assembly with anti-tangling function, through the setting of the first protective structure 2, can protect the cutter and prevent it from affecting the safety of surrounding workers. At the same time, the setting of the protective cover 207 prevents the cutter from getting tangled, affecting efficiency. In addition, the first motor 204 drives the threaded rod 201 to rotate, which can adjust the height of the protective cover 207 and the internal cutter, allowing the device to cut crops of different heights. In addition, with the submersible pump 206 and the water spray pipe 209, dust prevention or pesticide spraying can be carried out, greatly improving the practicality of the device. The setting of the second protective structure 3 can prevent tall crops from being broken by the protective cover 207, which would prevent the harvesting of this section of crops, affect the crop parameters, and cause waste. It can also protect the area in front of the device, preventing workers in front from being accidentally injured by the cutter, thus improving the safety of the device.
