[0036] In addition, in order to compact the tea leaves in the storage tube 800 and prevent the tea leaves in the storage tube 800 from becoming loose, a first rotating shaft 6008 and a second rotating shaft 60012 are rotatably connected to the outside of the mounting frame 6003, and a second pulley 60010 is fixedly connected to the outside of the first rotating shaft 6008 and the second rotating shaft 60012, and a second belt 60011 is sleeved on the outside of the second pulley 60010, and a bevel gear 6009 is fixedly connected to the outside of the first rotating shaft 6008 and the rotating rod 6001, and a vibration component for knocking the storage tube 800 is provided at the bottom of the second rotating shaft 60012.

[0038] Other embodiments may include a control system hardware structure, which is as follows: GNSS-based navigation and positioning systems, including the BeiDou system, etc.: In order to achieve precise operations and automatic control, the machine obtains decimeter-level positioning data from the park, uses differential technology, combined with base station remote sensing technology to improve positioning accuracy, and independently plans tea-picking routes.

[0039] Machine vision sensor control system: auxiliary navigation and positioning system. Due to the geometric characteristics of the tea garden environment, the ridges of the tea ridges become simple navigation reference targets. Through the visual sensor of this equipment to perceive these ridges, more accurate positioning information can be obtained to achieve navigation and positioning of agricultural machinery. During the operation of this equipment, the visual recognition module is installed at the front end of the machine body, collects the front image and performs image preprocessing, then performs data processing, and finally extracts the baseline of the operation line.

[0040] Inertial gyroscope self-balancing adjustment system: mainly used for the control of the self-balancing adjustment mechanism on both sides. Since the target operating area is a hill with a slope of less than or equal to 30 degrees, the gyroscope sensor and accelerometer can calculate the angular velocity and angle of the coordinates of the equipment, and then feed back to the lifting components on both sides for spontaneous adjustment, so that the whole equipment can remain level and operate.

[0041] It also includes a laser sensor, which cooperates with a visual sensor to detect the height difference between the target bud and leaf height and the first arc-shaped cutting blade 5005 and the second arc-shaped cutting blade 5006 to adjust the height position of the device. The laser sensor and the visual sensor are installed on both sides of the tea ridge. The laser sensor has the advantages of long distance measurement and high precision. In the tea garden environment, the buds and leaves are regarded as obstacles. Laser scanning is used to obtain the average height of the tea bushes, and the signal is input to the third motor 5003, so that the first arc-shaped cutting blade 5005 and the second arc-shaped cutting blade 5006 are more in line with the shape of the tea tree.

[0042] In addition, the intelligent control of the tea picking machine requires signal input from the actual scene. After sensing by laser sensors and visual sensors, the signal is processed and then transmitted to the controller to achieve intelligent control.

[0043] In the further design, the positioning module uses the NEO6M positioning module. The position receiver and the control center are connected to each other through the positioning satellite. The encoded GPS and other signal receiving devices are installed on this equipment. Before and during the operation of this equipment, the positioning system and ground remote sensing combined with certain algorithms can pre-compile the best cruise operation route and improve the accuracy during operation.

[0044] Among them, the slope sensing uses the MPU-6050 three-axis accelerometer electronic gyroscope, which has a built-in 16-bit AD converter and 16-bit data output. It has the advantages of high sensitivity, stable and reliable operation, and small size. The gyroscope sensor can also use the characteristics of the gyroscope to determine the direction of an object. During operation, the gyroscope can read its own direction signal by reading gravity and the axis angle, and then process the signal and transmit it to the control system, which is then controlled by the stepper motor.

[0045] Among them, machine vision uses photosensitive elements to receive external light signals, generate image information, and then filter out cluttered signals to identify three-dimensional objects. The camera unit of the visual system in this article uses a CMOS camera with a USB interface. To realize the automatic tea picking of the tea picker, in addition to the adaptive adjustment of the slope, it is also necessary to autonomously identify the operation target and identify and analyze the target treetops. Fresh buds and leaves have obvious color differences from older tea leaves. In addition, the colors of branches, soil, etc. are brown and black, which form a sharp contrast with the target objects. This difference is manifested in computer recognition as the R, G, and B components of the image. The algorithm can effectively divide the new shoots and background areas. During the operation of the tea picker, the blade is blocked, and it is difficult for us to make direct visual recognition of the position where the blade needs to work. The blade curve of the blade itself is known, so the spatial shape and position of the new shoots and background areas of the bush can be identified by the visual sensor while data processing is performed to fit a reasonable picker stroke.

[0046] Among them, the self-balancing control system first senses the slope signal by the gyroscope sensor, then determines the angle difference, calculates the height difference on both sides that needs to be adjusted, and converts it into the displacement that the nut block 4003 needs to move.

[0047] In the further design, the controller includes a single-chip microcomputer, a PLC, a DSP, an industrial control computer, etc. The controllers are used in different occasions due to different categories. The single-chip microcomputer is suitable for small machines, has strong comprehensive performance and high cost performance. The single-chip microcomputer receives control instructions and feeds back information, and can control the controlled object by writing a program, but the performance is not enough to control the tea picking machine; the PLC programmable controller is suitable for industrial production lines, and algorithm judgment is formed based on travel switches and various sensors; the industrial control computer is suitable for industrial production. Taking into account the advantages and disadvantages of each controller and comparing their portability and economy, the present invention selects a powerful 32-bit fixed-point DSP digital signal processor with a protection mechanism, which takes into account both control and fast calculation functions, and can well meet the control requirements.

[0048] The working principle of the control system is as follows: the control system in the present invention can be divided into a self-balancing control system, a driving system of the walking component, a control system of the third motor 5003, a blade efficiency control system, a rotation rate control system of the rotating rod 6001, a fan 1001 power control system and a power management system, etc.

[0049] In addition, the system design is implemented by CCS3.3 software, which has the functions of zeroing, serial communication, stroke detection, and forward and reverse rotation. After the control system is initialized, the control system enters the serial communication subroutine. When the input interrupt flag is detected to be 1, the data is received and transferred to the structure. When the end flag data is received, the communication is terminated. When the input interrupt flag is not 1, the operation is repeated until the interrupt flag is 1, and then the data reception and communication end steps are carried out.

The shaped cutting blades 5005 form staggered cutting to achieve cutting and picking of tea leaves, and the picked tea leaves are blown into the feeding frame 1006 by the wind blown by the blowing pipe 1004, and finally enter the feeding pipe 600. As the fourth motor 6004 drives the rotating rod 6001 to rotate, the rotating rod 6001 drives the flexible paddle 6002 to rotate, so that the tea leaves can be transported to the discharge pipe 6005 through the spiral flexible paddle 6002, and then transported to the storage cylinder 800 through the discharge pipe 6005 for storage; During the rotation of the rotating rod 6001, the mutual engagement of the bevel gears 6009 will drive the first rotating shaft 6008 to rotate, and the first rotating shaft 6008 will drive the second rotating shaft 60012 to rotate through the second pulley 60010 and the second belt 60011, and the second rotating shaft 60012 will drive the rotating block 700 to rotate, and the rotating block 700 will drive the knocking block 7001 to rotate, and the knocking block 7001 will continuously knock on the outside of the storage cylinder 800, so that the storage cylinder 800 vibrates, and the tea leaves in the storage cylinder 800 can vibrate, so that the tea leaves can be more compacted, and the storage cylinder 800 can be prevented from being filled up too early.
