[0002] Chinese cabbage is a common type of cabbage. Due to its morphological and planting characteristics, it is difficult to harvest. Generally, workers harvest it one by one, which is labor-intensive. With the development of technology, agricultural machinery that can automatically harvest Chinese cabbage has emerged.

[0003] At present, the existing Chinese cabbage harvester, such as the patent with publication number CN103797968A, discloses a semi-suspended Chinese cabbage harvester, which consists of a suspension frame, a transmission system, a wheeled frame, a pulling device, a flexible clamping mechanism, a cutting device, an inclined conveying device and a horizontal conveying device. The wheeled frame is used as a bearing chassis, the pulling device is installed at the bottom of the front end of the wheeled frame, and the cutting device and the flexible clamping mechanism are installed on the frame in sequence. An inclined conveying device parallel to the three is provided in the middle of the wheeled frame, and the pulling device, the cutting device, the flexible clamping mechanism and the horizontal conveying device are provided. The mechanism and the inclined conveying device are all designed to maintain an upward inclination angle of 15 degrees with the horizontal direction of the machine's forward movement, and are arranged perpendicular to the inclined conveying device in a top-down plane. The horizontal conveying device is installed at the rear of the wheeled frame, and the suspension frame is set on the left rear side of the wheeled frame. It is connected to the tractor in front through a three-point suspension. However, when the pulling mechanism of the above-mentioned device pulls out the cabbage, the pulling mechanism first acts on the cabbage.

The height of the crawler power chassis is appropriate and can cross common obstacles such as small earth ridges and shallow ditches without damaging the cabbage. The width of the crawler power chassis can be determined according to the cabbage planting row spacing to ensure good passability and provide stable and sufficient power to achieve smooth and efficient autonomous movement.

[0026] See also Figure 1 and Figure 2 Preferably, a seat 11 capable of accommodating an operator is provided in the operating compartment 1, and a plurality of observation windows 13 are provided on the operating compartment 1, through which the operator can observe the outside environment.

[0027] See also Figures 1 to 3The yoke 32 is provided with a plurality of cam 32s, and the cam 32s are provided with a plurality of cam 32s, and the cam 32s are provided with a plurality of cam 32s. The conveying channel 4 and the transfer conveying channel 4 are provided with a root cutting conveying channel 5 on the side away from the mounting plate 3. The root cutting conveying channel 5 is connected to the support frame 2. The transfer conveying channel 4 and the root cutting conveying channel 5 are both channels composed of plate-like structures that can allow cabbage to pass through, and the conveying directions of the transfer conveying channel 4 and the root cutting conveying channel 5 are perpendicular to each other; when in use, under the drive of the two transmission rollers 32 of each flexible conveying component, the mounting belts 31 of the two flexible conveying components rotate in opposite directions, and the mounting belts 31 drive the flexible clamping head 311 to move, thereby clamping the cabbage and conveying it to the side close to the transfer conveying channel 4 (if the weight of the cabbage is large, the transmission between the transmission roller 32 and the mounting belt 31 is relatively poor, the friction between the transmission roller 32 and the mounting belt 31 can be increased, so that the transmission roller 32 can more easily drive the mounting belt 31 to move).

[0028] See also Figures 1 to 3 Specifically, one of the transmission rollers 32 of each flexible conveying assembly is connected to the output shaft of the driving member 321, and the driving member 321 is connected to the support frame 2. The driving member 321 can drive the transmission roller 32 to rotate. If the power is insufficient when clamping the cabbage, the two transmission rollers 32 of each flexible conveying assembly can also be connected to the driving member 321, and the two driving members 321 of each flexible conveying assembly can be controlled to have the same rotation speed.

[0029] See also Figures 1 to 3 Preferably, the flexible layer is a rubber pad, which is soft and has a certain friction, so that it can firmly clamp the cabbage without causing any damage.

[0030] See also Figures 1 to 3 Preferably, the plate-like structures standing on both sides of the transfer conveying channel 4 are inclined toward the middle of the two vertical plates, so that the cabbage can be centered when receiving the cabbage.

During actual installation, the motor can be installed on the transfer conveying channel 4 or the root cutting conveying channel 5 to improve the stability of the conveyor belt 6. This is a conventional method used by those skilled in the art and will not be described in detail here). The conveying direction of the conveyor belt 6 in the transfer conveying channel 4 is the same as that of the transfer conveying channel 4, and the conveying direction of the conveyor belt 6 in the root cutting conveying channel 5 is opposite to that of the root cutting conveying channel 5. At the same time, the conveyor belt 6 in the transfer conveying channel 4 penetrates into the root cutting conveying channel 5, and the conveyor belt 6 with one end penetrated into the root cutting conveying channel 5 abuts against the conveyor belt 6 inside the root cutting conveying channel 5, and a first telescopic member 51 is provided inside the root cutting conveying channel 5, and a plurality of moving wheels 7 are provided on the transfer conveying channel 4 and the root cutting conveying channel 5, so that the mobile chassis 21 can drive the transfer conveying channel 4 and the root cutting conveying channel 5 to move; when the cabbage transported by the conveyor belt 6 in the transfer conveying channel 4 moves to the first telescopic member 51, the first telescopic member 51 pushes the cabbage, so that the cabbage is smoothly translated to the conveyor belt 6 inside the root cutting conveying channel 5, thereby completing the transfer of the cabbage.

[0032] See also Figures 1 to 5 A hollow groove 52 is provided on the root cutting conveying channel 5 on one side of the first telescopic member 51, and the hollow groove 52 is opposite to the conveyor belt 6 in the transfer conveying channel 4.

This is a mature existing technology, and its specific structure and use principle are not described here). A liftable cutter 541 is provided on the outside of the root cutting conveying channel 5 on the side of the hollow groove 52. When the sensor 53 detects that all the roots of the cabbage have entered the hollow groove 52, the cutter 541 is moved and the roots of the cabbage are cut off using the cutter 541.

[0033] See also Figures 1 to 5 Specifically, a second telescopic member 54 is provided outside the root cutting conveying channel 5 on one side of the hollow groove 52, and the output end of the second telescopic member 54 is connected to the cutter 541. The second telescopic member 54 can drive the cutter 541 to move, thereby completing the root cutting.

[0034] See also Figures 1 to 5 Preferably, the driving member 321 is a rotary motor, and the first telescopic member 51 and the second telescopic member 54 are both electric cylinders to provide power for the device.

An electric power storage device (such as a battery) is also provided in the operating compartment 1 to provide power for the electrical equipment.

[0036] See also Figures 1 to 5 When in use, the mobile chassis 21 is opened, and the mobile chassis 21 is used to move the transfer conveying channel 4 and the root cutting conveying channel 5 to the harvesting position, and the flexible conveying component is opened to clamp the cabbage and convey it to the side close to the transfer conveying channel 4. The conveyor belt 6 in the transfer conveying channel 4 conveys the cabbage to the hollow groove 52. When the sensor 53 detects that the roots of the cabbage have all entered the hollow groove 52, the cutter 541 is moved and the roots of the cabbage are cut off by the cutter 541. When the sensor 53 detects that the non-root part of the cabbage is facing the hollow groove 52 (that is, the root of the cabbage is located on the side away from the hollow groove 52), the conveyor belt 6 and the cutter 541 are stopped to prevent wrong cutting. The cabbage that has completed root cutting is pushed by the first telescopic member 51 and smoothly translated to the conveyor belt 6 inside the root cutting conveying channel 5, thereby transporting the cabbage out of the root cutting conveying channel 5.

[0037] The present invention provides a high-ground clearance gantry-type induction root-cutting Chinese cabbage harvester, comprising a flexible conveying component, which can quickly harvest Chinese cabbage and is suitable for cabbages of different sizes, shapes and growth postures. The flexible conveying component can firmly clamp the cabbage, ensure a stable conveying process, and avoid mechanical damage to the cabbage. The height of the mobile chassis is appropriate, and it can cross common obstacles such as small earth ridges and shallow ditches without damaging the cabbage. The width can be determined according to the cabbage planting row spacing to ensure good passability, and can provide stable and sufficient power to achieve smooth and efficient autonomous movement. When the sensor detects that the roots of the cabbage have all entered the hollow groove, the cutter is moved and the roots of the cabbage are cut off with the cutter to improve the accuracy of root cutting. In summary, the beneficial effects of the present invention are: the Chinese cabbage can be quickly harvested, damage to surrounding plants is reduced, and the accuracy of root cutting is improved. The machine is suitable for cabbages of different sizes, shapes and growth postures, and can firmly clamp the cabbage, ensure a stable conveying process, and avoid mechanical damage to the cabbage.
