[0030] Working principle:

[0031] When using the novel vegetable planting furrowing device to dig furrows during vegetable planting, a battery is installed inside the device to supply power to the electrical components inside the device;

[0032] Two coulter position adjustment stages:

[0033] When the distance between the two coulters 13 needs to be adjusted according to actual furrowing requirements, the first motor 301 is started, the first motor 301 drives the first screw 302 to rotate, the first screw 302 drives the threaded block 303 to move, the threaded block 303 drives the first support plates 304 on both sides to slide, the first support plates 304 drive the first support rod 305 to move, the first support rod 305 drives the second support rod 306 to move, the second support rod 306 drives the slider 307 to move, the slider 307 slides inside the cross plate 7 and drives the coulters 13 to move, and the distance between the two coulters 13 is adjusted to the required spacing, and the first motor 301 is turned off;

[0034] Adjustment of trenching depth:

[0035] The worm 401 is rotated, and the worm 401 drives the worm wheel 402 to rotate. The worm wheel 402 drives the rotating rod 403 to rotate.

After adjusting to the required height, the worm 401 is stopped. The height of the plow 13 can be adjusted. When digging furrows for vegetable planting, it is convenient to dig furrows of different depths. The worm 401 and the worm wheel 402 have a self-locking function. When the worm 401 is not rotated, the worm wheel 402 will not rotate, and the height of the plow 13 will not change. The height of the plow 13 can be adjusted manually without occupying electrical components, thereby reducing costs.

[0036] Trenching stage:

[0037] Start the second motor 10, which drives the crushing roller 9 to rotate. The crushing roller 9 crushes the soil that needs to be furrowed. The frame 1 is pushed manually, and the two plowshares 13 come into contact with the soil and furrow the soil. There are two plowshares 13, which can dig two furrows at the same time, and the furrowing efficiency is high. As the frame 1 is pushed, the roller 17 comes into contact with the furrowed soil and preliminarily flattens the higher raised soil. When the roller 17 presses on a harder object, the fourth bracket 15 slides toward the inside of the third bracket 14 to compress the spring 16. The spring 16 buffers the force received to prevent the roller 17 from coming into contact with a harder object and causing the entire device to flip upward. After the furrowing is completed by the furrowing device, subsequent vegetable planting is carried out.
