[0002] As a widely favored vegetable variety, the production and consumption of Chinese cabbage continue to grow globally, which reflects the increasing market demand for healthy food ingredients. However, despite the overall positive development trend of the Chinese cabbage industry, the application of technology in the harvesting link has revealed obvious limitations, especially in small-scale agricultural production scenarios.

[0003] At present, Chinese cabbage harvesting equipment mainly tends to serve large-scale operations, and most of the equipment circulating in the market is large-scale mechanized harvesting equipment designed for vast and flat farmlands. With their high operating efficiency and effective control of labor costs, such equipment has shown significant advantages in large farms. However, due to high investment costs, large machine volumes that are not easy to operate, and limitations in farmland adaptability, they are not suitable for small plots and small-scale farmland environments with variable terrains. Small-scale farmers still generally rely on labor-intensive manual harvesting methods. This traditional mode not only has extremely high labor intensity and low production efficiency, but also greatly increases the planting cost due to the rising labor costs in recent years.

[0033] Refer to Figures 1 to 6 , a small intelligent Chinese cabbage harvesting machine, including a vehicle body 100, a harvesting mechanism 200 is provided at the front end of the vehicle body 100, a collection box 400 is provided on the vehicle body 100, and the harvesting mechanism 200 includes a first conveyor module 210, a soil loosening knife rest 220, a vegetable harvesting lever module 230, and a positioning module 240. The first conveyor module 210 is inclinedly assembled with the vehicle body 100, the lower end of the first conveyor module 210 is located at the front end of the vehicle body 100, and the upper end of the first conveyor module 210 is higher than the collection box 400. The soil loosening knife rest 220 is fixedly assembled with the vehicle body 100, and the front end of the soil loosening knife rest 220 extends beyond the lower end of the first conveyor module 210. There are two groups of the vegetable harvesting lever modules 230, and the two groups of the vegetable harvesting lever modules 230 are respectively located on both sides of the first conveyor module 210. The positioning module 240 is fixedly assembled with the vehicle body 100, and the positioning module 240 is used to position the position of the Chinese cabbage.

[0034] The working principle of this small intelligent Chinese cabbage harvester is as follows: First, the operator starts the equipment. At this time, the built-in control system of the equipment is activated, ready to perform the harvesting task. Through the positioning module 240, the harvester can accurately identify and lock the position of the Chinese cabbage, and then automatically navigate to the predetermined harvesting area. After reaching the target position, the soil loosening tool holder 220 installed at the front end of the vehicle body 100 is inserted into the soil around the root of the Chinese cabbage to loosen the soil, so that the Chinese cabbage can be separated from the soil more easily, while reducing damage to the root system and surrounding crops.

[0035] Immediately afterwards, two groups of vegetable collecting lever modules 230 located on both sides of the first conveying module 210 work together to gently gather the loosened and easily movable Chinese cabbages towards the center and then send them to the first conveying module 210. This process ensures that the Chinese cabbage leaves will not be squeezed or torn, maintaining their intact appearance. The first conveying module 210 conveys the Chinese cabbages towards the vehicle body 100 and finally sends them into the collection box 400 located on the vehicle body 100.

[0036] The entire harvesting process not only improves the operation efficiency, but also reduces human contact and physical damage, greatly maintaining the freshness and quality of the Chinese cabbages. The harvested Chinese cabbages have no damage on the surface, and the shelf life is extended, ultimately bringing fresher and higher-quality vegetable products to consumers.

[0037] In this application, the first conveying module 210 includes a conveying ramp 211. Two groups of belt drive assemblies are relatively arranged on both sides of the conveying ramp 211, and a passage for the Chinese cabbages to pass through is left between the two groups of opposite drive assemblies. The belt drive assembly includes a driving roller 212, a driven roller 213, a conveyor belt 214 wound between the driving roller 212 and the driven roller 213, and a compression spring assembly. The compression spring assembly includes a plurality of compression spring frames 215 connected and fixed to each other. A pressure lever 216 is assembled on the compression spring frame 215 through a torsion spring. The pressure lever 216 is assembled with a pressing roller 217, and the pressing roller 217 presses on the conveyor belt 214 on the side facing the passage.

[0038] When conveying, the Chinese cabbages dialed by the vegetable collecting lever module 230 move upward along the conveying ramp 211 through the clamping of the conveyor belts 214 on both sides. The functions of the compression spring assembly are as follows: First, it provides sufficient friction force so that the Chinese cabbages can be firmly clamped and conveyed upward, avoiding the problem that the Chinese cabbages accumulate on the first conveying module 210 due to insufficient friction force. At the same time, it ensures that the conveyor belt 214 has sufficient elasticity to avoid the Chinese cabbages being squeezed by the conveyor belt 214. Second, it enables the Chinese cabbages to be conveyed in a lying posture, making the conveyance of the Chinese cabbages more stable and facilitating subsequent identification and sorting.

[0039] In addition, to ensure the stability of the upward oblique conveyance of Chinese cabbages along the conveyance ramp 211, the maximum inclination angle between the first conveyance module 210 and the ground is 35°, preferably 21°.

[0040] In this application, there are two groups of soil loosening knife racks 220. The two groups of soil loosening knife racks 220 are arranged oppositely, and a passage for the Chinese cabbages to pass through is left between the soil loosening knife racks 220. The soil loosening knife rack 220 is made by connecting a number of steel pipe fittings. The front end of the soil loosening knife rack 220 is in a converging shape and is close to the ground. The function of the pipe fitting structure is to ensure the structural strength of the soil loosening knife rack 220 and prevent the soil loosening knife rack 220 from cutting the Chinese cabbages. The front end of the soil loosening knife rack 220 is designed in an arc shape to prevent the Chinese cabbages from toppling during soil loosening.

[0041] In this application, the Chinese cabbage picking lever module 230 includes a Chinese cabbage picking lever frame 231. The Chinese cabbage picking lever frame 231 is connected to the vehicle body 100 through a first rotating unit 232. A second rotating unit 233 is assembled on the Chinese cabbage picking lever frame 231. The second rotating unit 233 is connected to an L-shaped picking lever 234, and a picking lever rod 235 is assembled on the picking lever 234. The Chinese cabbage picking lever module 230 uses the method of picking towards the middle to take the Chinese cabbages away from the land and pick them to the first conveyance module 210.

[0042] This application also has a sorting function, which is realized by a packaging mechanism 300. The packaging mechanism 300 includes a second conveyance module 310, a sorting picking lever module 320, and an identification module 330. The second conveyance module 310 is installed between the higher end of the first conveyance module 210 and the collection box 400. There are two groups of sorting picking lever modules 320. The two groups of sorting picking lever modules 320 are oppositely assembled on the conveyance path of the second conveyance module 310. The identification module 330 is assembled on one side of the second conveyance module 310. The collection box 400 is internally divided into a first collection cavity 401 for collecting qualified Chinese cabbages and a second collection cavity 402 for collecting unqualified Chinese cabbages. The two groups of sorting picking lever modules 320 cooperate to sort the Chinese cabbages and pick the Chinese cabbages into the first collection cavity 401 or the second collection cavity 402 according to the collection requirements.

[0043] Among them, the second conveyance module 310 is used to receive the Chinese cabbages conveyed from the first conveyance module 210. The identification module 330 uses visual recognition to detect and classify whether the Chinese cabbages have problems such as pests and diseases, bad leaves, and withered leaves. After classification, the sorting picking lever module 320 sorts the Chinese cabbages, picks the qualified Chinese cabbages to one side corresponding to the first collection cavity 401, and picks the unqualified Chinese cabbages to one side of the second collection cavity 402. The second conveyance module 310 operates, and the sorted Chinese cabbages fall into the corresponding cavities of the collection box 400.

[0044] It should be noted that, in order to prevent the surface of the Chinese cabbage from being scratched during transportation, the conveying ramp 211 of the first conveying module 210 and the second conveying module 310 both adopt a roller conveying structure, and the second conveying module 310 uses a chain drive module to drive the rollers.

[0045] To further improve the automation and intelligence level of the harvester, the collection box 400 is provided with double doors 410, and the vehicle body 100 is equipped with a door opening and closing drive unit 411 for controlling the opening and closing of the double doors 410. On one side of the collection box 400 opposite to the double doors 410, there are two push plates 420, and the two push plates 420 are respectively located in the first collection cavity 401 and the second collection cavity 402. The back of the push plate 420 is connected to a push drive unit 421. A sensor 430 is arranged in the collection box 400. When the sensor 430 senses that the Chinese cabbages harvested in the collection box 400 reach the collection limit, the harvester travels along the pre-planned path to a set location for unloading. During unloading, the door opening and closing drive unit 411 opens the double doors 410, and the push drive unit 421 drives the push plates 420 to push forward, pushing the Chinese cabbages out of the collection box 400 and dropping them at a designated location or into a designated container.

[0046] In addition, for the convenience of user control, the harvester further includes an intelligent control module and a terminal APP. The intelligent control module is installed on the vehicle body 100, and the terminal APP is wirelessly communicatively connected to the intelligent control module. The user can select different modes through the terminal APP installed on the mobile phone or controller to control the harvester to perform operations according to the actual usage scenario.

[0047] For example, in a scenario with a simple site, the user can select the fully automatic unloading mode through the terminal APP: the harvester automatically harvests the Chinese cabbages, and after reaching the collection limit, the harvester travels to the set location for unloading according to the pre-planned unloading path. In a scenario with a complex site, the user can select the semi-automatic unloading mode: when the sensor 430 detects that the Chinese cabbage harvest reaches the collection limit, the user is notified by means such as a buzzer alarm or a prompt from the terminal APP, and the user manipulates the harvester to travel to the set location for unloading through the terminal APP.

[0048] The protection scope of the present utility model includes but is not limited to the above embodiments. The protection scope of the present utility model is subject to the claims, and any substitutions, deformations, and improvements that are easily conceivable by those skilled in the art to this technology fall within the protection scope of the present utility model.
