[0033] Working principle:

[0034] First, adjust the depth of the discharge pipe into the soil according to the situation of the seeds to be sown. At this time, when adjusting the depth into the soil, you only need to loosen the fastening screw on the adjusting hoop, and then adjust the depth of the discharge pipe and then tighten it; then adjust the distance between the discharge pipes to ensure the sowing distance; specifically, you only need to slide the slider; here, as an extension of the present technical solution, multiple limit holes can be opened on the slide rail. After adjusting the position of the discharge pipe, the upper limit screw can be installed on the limit hole of the slide rail to further limit the position of the discharge pipe. The extension solution here is adjusted according to actual needs. This limit is not required during normal sowing, and there will be no large offset.

[0035] In addition, select a suitable seed wheel according to the size of the sowing seeds and install it inside the lower hopper; at the same time, select a driven wheel of corresponding size according to the actual situation to ensure the longitudinal spacing during sowing;

[0036] During actual sowing, the traveling wheel moves forward, and at the same time, the transmission belt drives the driven wheel to rotate, and the driven wheel drives the seed wheel to rotate through the intermediate shaft. When the seeds in the seed groove on the seed wheel rotate to the discharge port as the seed wheel rotates, the seeds fall to the discharge port, and then the seeds fall into the soil through the hose and the discharge pipe.

[0037] In the above embodiments and working principles, the slider and hose are provided to facilitate the user to adjust the spacing of each batch of seeds according to actual needs; the detachable connection between the seed wheel and the intermediate shaft facilitates the user to assemble different seed wheels according to different crops, thereby ensuring that a seed can be embedded in each seed slot; by detachably connecting the driven wheel and the intermediate shaft, it is convenient to adjust the size of the driven wheel according to different crops, thereby ensuring the sowing spacing of seeds in the same row; by tightening the screw on the adjusting hoop, the extension depth of the discharge pipe is adjusted according to the different burial depths of the crop seeds.
