[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figures 1-4 This utility model embodiment of a cruciferous vegetable harvester includes a chassis 1 and a shearing mechanism 9. Wheels are installed at the four corners of the bottom of the chassis 1, with axles fixedly connected between two wheels. The axles are movably connected to the chassis 1. A U-shaped limiting member 10 is fixedly connected to the upper outer surface of the chassis 1. The main frame 2 passes through the U-shaped limiting member 10 and forms a pin connection with the chassis 1, thus connecting the chassis 1 and the main frame 2. Two main frames 2 are installed on the upper part of the chassis 1. A harvesting component is fixedly connected to the rear side of each main frame 2. A conveyor is installed on one outer surface of each of the two main frames 2. The structure includes a conveyor belt 8 on the upper outer surface of the main frame 2, a drive shaft 7 that movably passes through the inner surface of the main frame 2, and a transmission connection between the outer surface of the drive shaft 7 and the conveyor belt 8. A reversing gear 6 is provided on the outer surface of the drive shaft 7. A spiral adjusting rod 11 is provided inside the two main frames 2, and the spiral adjusting rod 11 is threaded to the inner surface of the two main frames 2. By rotating the spiral adjusting rod 11, the distance between the two main frames 2 can be adjusted, thereby adjusting the distance of the shearing mechanism 9. This structure is suitable for harvesting cruciferous vegetables in different distances and terrains, improving the adaptability of the device.

[0026] A retaining ring 12 is movably connected to the outer surface of the drive shaft 7. A reversing gear 6 is fixedly connected to the outer surface of the retaining ring 12. A bolt 13 is provided on the outer surface of the retaining ring 12. A slot is opened on one side of the outer surface of the retaining ring 12. A positioning hole 14 is opened on the outer surface of the drive shaft 7. The bolt 13 is threaded to the inner surface of the positioning hole 14 through the slot.

[0027] The above structure, through the setting of the fixing ring 12, bolt 13, positioning hole 14 and slot, realizes the movement of the reversing gear 6, so that when pushing the machine forward during non-operation time, the reversing gear 6 can slide out of engagement to reduce the force required to push forward.

[0028] The transmission mechanism includes first synchronous pulleys 3 fixedly connected to the outer surfaces of both sides of the rear axle. A conveyor belt 4 is connected to the outer surfaces of both first synchronous pulleys 3. A second synchronous pulley 5 is connected to the upper inner surface of the conveyor belt 4. A reversing gear 6 is meshed with the outer surface of the second synchronous pulley 5.

[0029] The above structure, through the arrangement of the first synchronous pulley 3, the conveyor belt 4, the second synchronous pulley 5 and the reversing gear 6, realizes the human-powered conversion of forward thrust into the upward rotational force of the conveyor belt 4, eliminating the need for a power device for the conveying mechanism.

[0030] The shearing mechanism 9 includes two blade holders 93 fixedly connected to the outer surface of the front side of the main frame 2. The inner surfaces of the two blade holders 93 are slidably connected to blade connecting rods 94. The other end of the blade connecting rods 94 is movably connected to the blade holder 91. The blade holder 91 includes a U-shaped clamping plate, a movable rod, and a limiting block. The U-shaped clamping plate, the movable rod, and the limiting block are all fixedly connected. The blade body 95 is also movably connected inside the U-shaped clamping plate. A return spring 92 is fixedly connected to one outer surface of the two blade holders 93. The return spring 92 is movably connected to the outer surface of the movable rod.

[0031] The aforementioned mechanism, through the arrangement of blade holder 91, return spring 92, blade assembly frame 93, blade connecting rod 94 and blade body 95, allows the two blade bodies 95 to contact the plant roots when the vehicle moves forward. Under the resistance of the plant, the included angle between the two blade bodies 95 decreases, thus cutting the plant. This achieves plant cutting using only resistance, eliminating the need for a power unit for the cutting mechanism.

[0032] Working principle: When using this cruciferous vegetable harvester, the operator pushes the vehicle forward, causing the wheels and axles to rotate. This rotation drives the first synchronous pulley 3, the conveyor belt 4, the second synchronous pulley 5, and the reversing gear 6 to rotate, which in turn drives the drive shaft 7 and the conveyor belt 8 to rotate upward, transporting the cut plants to the rear of the device for collection. At the same time, as the vehicle moves forward, the shearing mechanism 9 at the front of the device has two blades 95 contacting the roots of the plants. Under the resistance of the plants, the angle between the two blades 95 decreases, cutting the plants. The shearing mechanism 9 and the conveying mechanism do not require an additional power source other than human power, saving energy and material costs.

[0033] Before harvesting, the harvesting distance between the two harvesting components can be adjusted by rotating the spiral adjusting rod 11. When the machine is being pushed forward during non-operational time, the reversing gear 6 can be slid out of engagement to reduce the force required to push forward.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
