Through the touch screen, the operator can easily set and adjust these parameters to adapt to different environments, working conditions and separation requirements. The separation assembly 8 is equipped with an emergency stop button. The emergency stop button can quickly cut off the power supply in an emergency to prevent the situation that the foreign matter gets stuck in the movable roller 83 and causes the mechanism to fail.

[0029] In the embodiment, the output end of the cutting motor 51 drives the cutting tooth 54 to rotate through the speed reduction gear set, so that the Chinese cabbage can be cut from the root. In order to ensure the safety of the user, the cutting mechanism 5 is provided with an emergency stop switch. The cutter cuts the root of the Chinese cabbage entering the clamping groove 4 through the side groove 22.

[0030] The extrusion assembly 3 comprises an extrusion roller assembly 31 and a mounting baffle 32, the mounting baffle 32 is movably installed at the two ends of the extrusion roller assembly 31, the mounting baffle 32 is fixedly installed on the left and right sides of the front vegetable plate 2, the extrusion roller assembly 31 comprises an extrusion motor 312, the output end of the extrusion motor 312 is fixedly sleeved with a mounting rod 313, the surface of the mounting rod 313 is fixedly sleeved with an extrusion roller 314, the middle part of the extrusion roller 314 is integrally formed with an arc-shaped groove 315, and the surface of the extrusion roller 314 is provided with anti-skid teeth 316.

[0031] In this embodiment, in order to ensure that the Chinese cabbage is smoothly cut into the V-shaped conveyor belt 7, the rotating extrusion roller assembly 31 can apply pressure and friction to the Chinese cabbage below it after entering the clamping groove 4, thereby achieving the purpose of extrusion harvesting and transporting the Chinese cabbage backward. The extrusion roller 314 is driven to rotate by the extrusion motor 312 installed on the side of the front cabbage plate 2, and the surface of the extrusion roller 314 is provided with anti-skid teeth 316 to increase the friction between the extrusion roller 314 and the Chinese cabbage during operation, ensuring that the extrusion roller 314 can fully contact the Chinese cabbage without slipping, and the posture of the Chinese cabbage is ensured by the arc-shaped groove 315.

[0032] One side of the extrusion motor 312 is fixedly installed with a sliding block 311, the middle part of the baffle 32 is provided with a sliding groove 321, the sliding block 311 is movably installed in the sliding groove 321, and the sliding block 311 and the sliding groove 321 are fixedly connected with a spring 33. One side of the extrusion motor 312 is fixedly installed with a motor bracket 317, a pulley is fixedly installed on the side surface of the motor bracket 317, the pulley is matched with the side surface of the sliding groove 321, so as to support the weight of the extrusion motor 312 and reduce the friction resistance through sliding.

[0033] In this embodiment, the spring 33 can adapt the extrusion roller assembly 31 to different sizes of Chinese cabbage, and make the extrusion roller 314 fully contact the top end of the crop, avoiding the problem that part of the Chinese cabbage is too small to contact the extrusion roller 314. Moreover, due to this spring, the small agricultural machine can set the extrusion roller 314 as a self-adaptive pressure head, greatly improving the harvesting capacity of the front cabbage plate 2.

[0034] By adjusting the rotating speed of the extrusion roller 314 and the setting of the clamping groove 4, the stress condition of the Chinese cabbage during extrusion can be accurately controlled, so as to accurately control the motion form and motion track of the Chinese cabbage during harvesting.

[0035] It also includes a remote control and a signal receiver, the signal receiver is installed in the small agricultural machine, and the working principle of the remote control transmitting signals to the signal receiver is based on radio wave transmission. Inside the remote control, there is a micro transmitter, when the button is pressed, the transmitter will generate a specific frequency of radio wave signal. These signals are transmitted through the air and captured by the signal receiver. Inside the signal receiver, there is an antenna and a signal processor. The antenna receives radio waves from the remote control, and the signal processor decodes these signals and converts them into electrical signals. These electrical signals are then transmitted to the control circuit of the receiver, triggering corresponding actions, such as starting or stopping the cutting mechanism 5, the inclined support plate 6, the separation assembly 8 and the movement of the driving base 1, etc.

[0036] In the small agricultural machine, a photoelectric sensor is installed on the top of the inner cavity of the front cutting board 2 to detect the position of the Chinese cabbage. The photoelectric sensor is used to detect whether the Chinese cabbage enters the front clamping groove 4 during the forward movement of the harvester. If the light beam emitted by the transmitter is blocked by the entering Chinese cabbage, i.e. the receiver does not receive the signal, a signal is sent to the rear mechanisms to start operating, ensuring that the harvester can work energy-efficiently, stably and efficiently. The non-contact design avoids mechanical wear and pollution, improves the service life and reliability of the sensor. At the same time, the photoelectric sensor has the advantages of fast response speed and high precision, providing strong support for the intelligence and automation of the harvester.

[0037] Working principle: After the Chinese cabbage enters the clamping groove 4, the rotating extrusion roller assembly 31 can apply pressure and friction to the Chinese cabbage below it, thereby achieving the purpose of extruding and transporting the Chinese cabbage backward. The extrusion roller 314 is driven to rotate by the extrusion motor 312 installed on the side of the front cutting board 2, and the surface of the extrusion roller 314 is provided with anti-skid teeth 316 to increase the friction between the extrusion roller 314 and the Chinese cabbage during operation, ensuring that the extrusion roller 314 can fully contact the Chinese cabbage without slipping, and the posture of the Chinese cabbage is ensured by the arc-shaped groove 315. After the mature Chinese cabbage is harvested by the harvesting mechanism, it is lifted by the V-shaped conveyor belt 7, enters the top of the inclined separation assembly 8, and the separation assembly 8 slides downward due to gravity. The movable roller 83 rotates in the opposite direction to slow down the downward speed of the separation assembly 8, so that the relative motion between the movable roller 83 and the Chinese cabbage generates a large friction force, tearing the leaves from the stem or leaf vein connection, thereby achieving the purpose of separating the main body of the Chinese cabbage from the external leaves.
