[0029] In the picture: 5-frame; 6-cabbage; 61-root. Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] See attached document Figures 1-13 The diagram shows a suspended cabbage harvester, including a pulling mechanism for uprooting cabbages buried in the ground and detaching them from the surface. The specific structure is as follows... Figure 1-3 As shown in Figures 5-6, the method includes symmetrically arranged cone-shaped pulling posts 1 along the planting row of the cabbage and located on the left and right sides of the cabbage. The spacing between these symmetrical pulling posts 1 is between the width of the cabbage body and the width of its root. For example, Figure 3 As shown, the cone-shaped extraction column 1 forms a large opening for the cabbage to enter, allowing the cabbage to smoothly enter the symmetrical extraction column 1. Since the spacing between the symmetrical extraction columns 1 is between the width of the cabbage body and its root, the extraction column 1 avoids contact with the cabbage root as it moves forward, while simultaneously supporting the cabbage body above the root. The spacing between the cone-shaped extraction columns 1 gradually decreases towards the rear. As the cabbage moves towards the cone, it is continuously lifted upwards within the narrowing opening, utilizing the arc-shaped circumferential structure at its base, thus detaching the root from the ground and completing the extraction operation.

[0032] During the process of the pulling column 1 moving forward to pull the cabbage, the pulled cabbage will be affected by the forward unidirectional driving force applied by the pulling column 1 during the pulling process, such as... Figure 11 As indicated by the middle arrow a, this will cause the cabbage to flip forward. Figure 11 As indicated by arrow b), the cabbages tip over and fall from the pulling column 1 onto the ground. During continuous harvesting, the continuous forward movement of the pulling column 1 causes the cabbages to be crushed and damaged on the ground. Therefore, to solve this problem, such as... Figure 12As shown, the top surface of each of the pulling columns 1 is configured as a sloping structure that drives the cabbage to tilt towards the picking mechanism (as shown in Figure 1a). Before pulling, since the roots of the cabbage are buried in the ground, the cabbage is in a relatively stable state, which can overcome the contact force of the pulling column 1 on its side wall. However, after the cabbage is pulled up and lifted off the ground, it is in a free state supported by the pulling column 1 and will tilt freely due to the uneven distribution of gravity. Therefore, this application sets the top surface of the extraction column 1 as a slope structure facing backward, so that the height of the rear side of the extraction column surface is lower than that of the front side. Since the front side of the cabbage is in contact with the surface of the extraction column 1, while the rear side is in a suspended state without contact with the surface of the extraction column 1, under the action of gravity, the cabbage will turn backward and contact the rear side of the surface of the extraction column 1, so that the cabbage itself is in a stable supporting state, thereby avoiding the problem of the extracted cabbage tilting forward and falling to the ground surface, as well as the problem of squeezing damage caused by the extraction column 1 during its movement, thus realizing the smooth extraction operation of the cabbage.

[0033] The root-cutting mechanism separates the root of the cabbage from the cabbage body after it detaches from the ground. The specific structure is as follows: Figure 3 , 7 As shown, the root-cutting mechanism consists of root-cutting wheels 2 arranged between symmetrical pulling posts 1. These wheels are preferably saw gears and can be driven to rotate by a motor or by the harvester's axles and a gear transmission mechanism. After a single cabbage is successfully pulled out by the pulling posts 1, the cabbage is lifted onto the posts 1, while the harvester continues to move forward. The cabbages that are subsequently pulled up and lifted onto the posts 1 will drive the previously pulled cabbages to move backward. During this movement, the connection between the cabbage body and the root will come into contact with the root-cutting wheels 2. The root-cutting operation is achieved by rotating the root-cutting wheels 2.

[0034] The picking mechanism is used to pick up and arrange the detached cabbage stems, and its specific structure is as follows: Figure 3 , 8 As shown in Figure -10, the picking mechanism consists of symmetrically arranged picking conveyor belts 3 connected to the rear side of the picking column 1. After the cabbages are cut at the root, they are tilted between adjacent picking conveyor belts 3 by the subsequent cabbage driving action. These picking conveyor belts 3 are preferably inclined upwards, allowing the cut cabbages to be arranged sequentially upwards and conveyed by the opposing picking conveyor belts 3 on both sides. Once the cabbages are conveyed to the top, it facilitates packaging and packing operations.

[0035] Because Chinese cabbage has a high water content, during the process of picking and conveying the cabbage via the symmetrically arranged left and right conveyor belts 3, the two conveyor belts 3 exert a certain clamping force on the sides of the cabbage. This clamping force can cause squeezing and damage to the side walls of the cabbage. The high water content of the cabbage will cause it to rot prematurely during later packaging and transportation, affecting its sale. Therefore, to solve this problem, this application also includes a protective structure for the cabbage picking process, such as... Figure 1 , 13 As shown, the protective structure is such that each of the picking conveyor belts 3 is inclined outwards. This arrangement causes the picking conveyor belts 3 on both sides to form a conical inner cavity, allowing the cabbage after the roots are cut to fall into this conical cavity. This achieves a lifting contact state between the picking conveyor belts 3 and the cabbage. In this state, the picking conveyor belts 3 do not have a clamping force on the cabbage (indicated by arrow c in the figure). Instead, the cabbage is transported upwards by the friction between its weight and the picking conveyor belts 3. Compared to a vertically arranged picking conveyor belt 3, this effectively avoids the problem of clamping and damaging the side walls of the cabbage, thus effectively protecting the cabbage during harvesting.

[0036] The conveyor mechanism transports the picked-up and arranged cabbage bodies, with the specific structure as follows: Figure 1 , 10 As shown, the conveying mechanism is a conveyor belt 4 vertically positioned at the end of the picking conveyor belt 3. The picked-up cabbages, after being cut at the root, are arranged and conveyed via the picking conveyor belt 3. After reaching the top of the picking conveyor belt 3, they fall onto the conveyor belt 4 for further conveying. During this conveying process on the conveyor belt 4, the cabbages can be packaged and packed, enabling the harvester to perform the functions of picking, cutting, arranging, conveying, and packing cabbages. A container can be installed on one side of the conveyor belt 4 to store the packed cabbages.

[0037] The above-mentioned structures can be installed together on the frame 5. Wheels can be installed at the bottom of the frame, and the frame can be suspended and pulled through the side walls of the frame. Tractors and other agricultural machinery can be used for pulling.

[0038] The principle of this application is as follows: the harvester is pulled onto the agricultural machinery by the frame of the harvester and moves through the cabbage planting field. During the movement, the pulling column 1 is located on both sides of the cabbage. When the cabbage enters the pulling column 1, the cabbage is pulled upward by the gradually narrowing gap of the pulling column 1, so that the cabbage root is detached from the ground. Then, the cabbage root of the previously pulled cabbage is driven to contact the root cutting wheel 2 by the subsequent pulled cabbage, so as to cut off the cabbage root. Then, the cabbage after the root is cut is poured onto the symmetrical picking conveyor belt 3 by the subsequent pulled cabbage and is lifted and conveyed upward. When it is conveyed to the conveyor belt 4, the cabbage can be wrapped and packaged.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
