Description

Technical Field

[0001] This invention pertains to agricultural cumin harvesting machinery, specifically a machine for harvesting and collecting whole cumin plants. Background Technology

[0002] Cumin is a spice crop with a short maturity period, which can be sown alone or intercropped with multiple crops. It is one of the choices for improving the quality and efficiency of agricultural production. Currently, cumin production is basically carried out by manual harvesting, which is costly, inefficient, and affects the secondary planting of land. The key to solving the problems of low-cost and rapid harvesting, early land clearing for secondary planting, ensuring crop maturity, and increasing total land income is mechanization. This device was invented to solve this problem.

[0003] Currently, there are basically two models for cumin harvesting. 1. Completely manual uprooting: This model relies on a large workforce for manual uprooting, which requires a large amount of labor, is difficult to organize and manage, and makes it impossible to clear the land on time.

[0004] 2. Using a harvesting platform to cut and spread hay, then collecting it from the field, results in high stubble loss and grain loss after spreading and picking it up. Therefore, this method leads to relatively large losses and has a complex production process.

[0005] Therefore, there is a need to develop a cumin harvesting device that can harvest the entire cumin plant, completely solving the problems of the above-mentioned harvesting methods, and providing a highly efficient and low-loss harvesting principle and equipment that can clear the land surface in one go. Summary of the Invention

[0006] The purpose of this invention is to provide a whole-plant harvester for cumin crops. It has a reasonable and compact structure, strong adaptability, and can complete the uprooting, centralized transportation and collection of crops in one operation, realizing the whole-plant recovery of crops, reducing crop recovery costs, improving crop recovery efficiency and reducing losses. It can also clear crops from the land surface in one operation, providing convenient conditions for subsequent field management, reducing the labor intensity of workers and improving their work efficiency.

[0007] The objective of this invention is achieved as follows: a whole-plant harvester for cumin crops, comprising horizontally evenly arranged lifting, clamping, and conveying devices mounted on the front of the harvester's frame via hinge connections and floating critical point holding devices. Each lifting, clamping, and conveying device consists of a divider and a clamping and conveying assembly with a grain-pulling disc at the front. A V-shaped divider is positioned at the front of the support of the lifting, clamping, and conveying device, with the divider's inlet corresponding to the gap formed between the left and right clamping and conveying assemblies. The discharge end of the lifting, clamping, and conveying device is connected to the conveyor belt of a horizontally arranged centralized conveyor belt, and the discharge end of the centralized conveyor belt is connected to the inlet of a bridge-lifting conveyor.

[0008] The present invention includes a harvester frame, on which a centralized conveyor belt is installed, a lifting and clamping conveyor with a V-shaped inlet and a bridge lifting conveyor, and a longitudinally arranged whole-plant lifting device for crops whose outlet is connected to the conveyor device.

[0009] This invention relates to a whole-plant harvesting device for crops, comprising a centralized conveyor belt on a harvester's frame, a harvesting and clamping conveyor, and a transmission device. The harvesting and clamping conveyor is hinged to the frame, and its outlet corresponds to the centralized conveyor belt, which in turn corresponds to a bridge-lifting conveyor.

[0010] The lifting, clamping, and conveying device is an independent unit connected to the harvester's frame via hinges. The structure consists of a front driven wheel mounted on a support frame, with a reeling disc mounted on it. A drive sprocket, connected to a bearing on the support frame, is located in the middle of the frame. A rear driven wheel, providing both transmission and tensioning functions, is located at the rear of the support frame. A sliding track on the support frame acts as a clamping conveyor component, which reels and clamps the crop, preventing material slippage. A reeling plate is mounted on the upper end of the front driven wheel axle. The circular conveyor belt is composed of a belt or chain. A floating critical point holding device is installed between the harvester's frame crossbeam and the lifting, clamping, and conveying device. Its function is to maintain the lifting, clamping, and conveying device in a floating state, promptly springing up when encountering even small obstacles to ensure safe operation. The pressure-bearing floating device is a compression spring or a compressed gas cylinder.

[0011] The transmission box can be either mechanical or hydraulic. The transmission box is powered by a mechanical motor or a hydraulic motor, and the drive sprockets use an S-shaped arrangement to achieve relative rotation of the lifting and clamping conveyor devices on both sides. A centralized conveyor belt is installed in the middle of the harvester's frame, transporting centralized materials via a flat belt. A bridge-lifting conveyor is installed below and behind the centralized conveyor belt, its function being to lift the materials transported by the centralized conveyor belt and convey them to the rear.

[0012] Crops are pulled into the gaps between the left and right pulling clamping conveyors by the clamping and conveying components. The clamping and conveying components are driven by the active sprocket to pull up the crops. The pulled crops are then conveyed backward by the clamping and conveying components onto the centralized conveyor belt. The left and right centralized conveyor belts quickly send the crops into the bridge lifting conveyor, which then conveys the material backward to the connected main machine.

[0013] The advantages of this invention are that it clears its own path during operation, and can uproot and clear both thin and thick stalks in one go. It is highly adaptable to different crops, with high harvesting efficiency and a high uprooting rate. The number of power rows can be increased or decreased at any time according to the number of power rows of the matching implements.

[0014] This invention has a reasonable and compact structure and strong adaptability. It can complete the uprooting, centralized transportation and collection of crops in one go, realize the whole-plant recovery of crops, reduce the cost of crop recovery, improve the efficiency of crop recovery and reduce losses. It can also clear crops from the land surface in one go, providing convenient conditions for subsequent field management. Attached Figure Description
