Description

Technical Field

[0001] This utility model relates to the field of cumin harvesting technology, specifically to a self-propelled precision cumin harvester. Background Technology

[0002] Cumin, as a spice crop with high economic value, is widely planted using plastic film mulching and is often intercropped with crops such as corn and sunflower.

[0003] Traditional manual harvesting suffers from low efficiency, high labor intensity, and a tendency to tear plastic film. Existing mechanical harvesting equipment mostly uses rigid reels or cutting devices, which easily damage the plastic film and cannot adapt to the narrow row spacing of intercropped crops. Lodging plants result in a high rate of missed harvesting due to the lack of effective straightening mechanisms, and traditional clamping mechanisms are prone to grain loss. In addition, large harvesting machinery has great limitations in maneuvering in intercropped fields.

[0004] Therefore, there is an urgent need for a self-propelled precision cumin harvester to improve the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a self-propelled precision cumin harvester that, through the coordinated action of a V-shaped clamping belt and a vertical passive roller, achieves integrated flexible clamping of the plant and straightening of lodged plants, reducing grain loss rate, thereby solving the problems mentioned in the background art.

[0006] Existing mechanical harvesting equipment mostly uses rigid reels or cutting devices, which can easily damage the mulch film, cannot adapt to the narrow row spacing of intercropped crops, and lodged plants have a high rate of missed harvesting due to the lack of effective uprighting mechanisms, which can easily cause grain loss.

[0007] To achieve the above objectives, this utility model provides a self-propelled precision cumin harvester, including a frame with a through groove, and a seed divider guide at the front end of the frame;

[0008] The upper part of the frame is equipped with a harvesting mechanism consisting of a pair of vertical passive rollers and a clamping belt surrounding them, and the working section of the clamping belt forms a V-shaped clamping channel.

[0009] The separating guide and the clamping belt work together to separate the plants. The passive roller is configured to straighten the lodged plants. The frame is slidably connected with a set of walking wheels, which is configured to avoid damaging the plastic film during harvesting.

[0010] In the above technical solution, the involute-shaped dividing guide at the front of the frame is inserted between the rows of intercropped crops to separate the cumin plants to be harvested from the adjacent crops. At the same time, it sorts out the messy stems and guides the plants along the predetermined path into the harvesting area. The vertically set passive roller contacts the fallen plants as the equipment moves forward. Using the friction and rotation of the roller surface, the fallen stems are gradually lifted to an upright state, ensuring that the plant roots are detached from the mulch film and enter the clamping area. The V-shaped clamping belts rotate in opposite directions under the drive of the motor. The walking wheel set, which is slidably connected to the through groove of the frame, adaptively adjusts its height according to the terrain. The wide wheel surface disperses the pressure when in contact with the mulch film, and the outward tilt design reduces slippage friction, so as to achieve stable equipment movement while avoiding tearing the mulch film.

[0011] Based on this, the power unit is fixed to the frame via a bracket and coaxially connected to the passive roller, driving the clamping belt to achieve bidirectional synchronous transmission, so that the belts on both sides of the V-shaped clamping channel move in opposite directions, realizing continuous clamping and conveying of the plant; at the same time, the sliding tension roller on the side of the frame through the slot moves along the preset track through the displacement adjustment mechanism, pressing against the inner surface of the clamping belt in real time, dynamically compensating for the deformation of the belt caused by load changes, maintaining constant tension, and ensuring stable clamping force and transmission efficiency.

[0012] In another technical solution, the walking wheel set adopts two sets of wide wheels with anti-slip texture on the surface of the wheels, and the clamping belt adopts a segmented structure with equidistant ventilation holes along the length direction.

[0013] In this technical solution, the wheel surface is provided with anti-slip texture to enhance field adhesion; at the same time, the clamping belt adopts a segmented structure to reduce the accumulation of adhering substances on the belt surface and improve heat dissipation performance.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This self-propelled precision cumin harvester achieves integrated flexible clamping of plants and straightening of lodged plants through the coordinated action of a V-shaped clamping belt and a vertical passive roller, reducing the grain loss rate. The walking wheel set adopts a wide anti-slip wheel body with a specific outward tilt angle design to disperse ground pressure and effectively protect the integrity of the mulch film. The composite material clamping belt has both high friction and elastic deformation characteristics, ensuring clamping force while avoiding stem damage. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] For now, please refer to Figures 1-3 As shown, this embodiment provides a self-propelled precision cumin harvester, including a dividing guide 110. A harvesting mechanism 200 is provided on the upper part of the frame 100, consisting of a pair of vertical passive rollers 230 and a clamping belt 210 surrounding them. The working section of the clamping belt 210 forms a V-shaped clamping channel. The dividing guide 110 and the clamping belt 210 cooperate to separate the plants. The passive rollers 230 are configured to straighten the lodged plants. A set of walking wheels 150 is slidably connected in the through groove 140 of the frame 100. The set of walking wheels 150 is configured to avoid damaging the mulch film during the harvesting process.

[0024] During implementation, the separating guide 110 first separates the plants and guides them to the harvesting area; the vertical passive roller 230 straightens the fallen plants, making them stand upright and enter the V-shaped clamping channel formed by the clamping belt 210. The two belts move synchronously towards each other, flexibly clamping the plant stems and conveying them backward; at the same time, the walking wheel set 150, which is slidably connected to the through groove 140 of the frame 100, disperses the ground pressure through the wide wheel surface and anti-slip structure, and adaptively adjusts the height during travel to avoid crushing or scratching the mulch film, thus achieving efficient and low-loss harvesting.

[0025] See Figure 1 As shown, the clamping belt 210 uses a flexible picking method. After the cumin plant passes through the dividing guide 110, the fruits on the cumin plant are picked by the friction of the surface of the clamping belt 210. The cumin fruits are collected by the guidance of the clamping belt 210.

[0026] Figure 2In the middle, the rear of the frame 100 is equipped with a handle 130 with an operating table. When working, the operator holds the handle 130 and operates the corresponding buttons on the operating table. Because the operating table integrates a drive control unit, the control unit is connected to the power unit through a cable, so that the machine can harvest cumin normally.

[0027] The anti-slip treads on the wheel surface embed into the soil surface to create a meshing effect. When the wheel travels between the rows of intercropped crops, it not only prevents the wheel from slipping and crushing the plants, but also avoids damage to the mulch film by reducing the pressure per unit area. The segmented clamping belt 210 achieves local flexible deformation through the hinged components to adapt to the clamping needs of plants of different thicknesses.

[0028] Additionally, see Figure 2 As shown, the equidistant ventilation holes create periodic airflow disturbances during belt operation, effectively removing attached stem residues and accelerating the dissipation of heat generated by friction between the belt and the plant, preventing rubber aging caused by temperature rise and maintaining uniform clamping force and continuous operation.

[0029] See Figure 3 As shown, the tension roller 240 moves along a preset track on the side of the through groove 140 of the frame 100 via a displacement adjustment mechanism, continuously pressing against the inner surface of the belt 210, and dynamically adjusting the contact pressure according to the tension changes of the belt during operation. This compensates for belt deformation to maintain constant tension.

[0030] The vertically positioned passive roller 230 contacts the fallen plants as the equipment moves forward. It uses the friction and rotation of the roller surface to gradually lift the fallen stems to an upright position, ensuring that the plant roots are freed from the mulch film and enter the clamping area. The V-shaped clamping belt 210 rotates in opposite directions under the drive of the motor, using elastic clamping force to wrap around the lower part of the plant stem. The flexible toothed strip on the belt surface provides frictional traction force, which conveys the plant backward at a uniform speed. During the process, the clamping force is kept uniform to avoid the grains falling off.

[0031] In this embodiment, a self-propelled precision cumin harvester is used in which the dividing guide 110 first separates the cumin plants between the intercropped crop rows and guides them to the harvesting area. The vertical passive roller 230 then straightens the fallen plants, making them stand upright and enter the V-shaped clamping channel formed by the clamping belts 210. The power unit 220 drives the passive roller 230 coaxially to drive the clamping belts 210 on both sides to rotate in opposite directions, conveying the plants at a uniform speed with a flexible clamping method. At the same time, the sliding tension roller 240 dynamically adjusts the belt tension to ensure stable clamping force. The wide anti-slip wheels of the walking wheel set 150 protect the mulch film from damage during the adaptive height adjustment process by dispersing ground pressure and engaging the ground surface with anti-slip patterns, achieving low-resistance and stable movement.

[0032] After being conveyed to the end by a belt, the clamped plants fall by gravity to the collection bin 120 at the rear of the frame 100 for collection. The drive control unit on the operating table adjusts the speed of the power unit 220 in real time to match different plant density conditions. The equidistant ventilation holes of the segmented clamping belt 210 remove stem residue and accelerate heat dissipation during operation, while the outward tilt design of the symmetrical wide wheel body further enhances the stability of the equipment in straight-line travel, ultimately achieving efficient and precise harvesting with zero damage to the mulch film and low grain loss.
