[0038] like Figure 1-6As shown, when sowing, the seeds to be sown are loaded into the seed storage chamber 301 in advance, and the fertilizers to be fertilized are loaded into the fertilizer storage chamber 302; the transfer slider 106 is driven to move leftward by the contraction of the output end of the electric cylinder 105, and the transfer slider 106 rotates with the first rotating bracket 101 when moving leftward, so that the bottom end of the first rotating bracket 101 moves leftward, and then the first rotating bracket 101 and the second rotating bracket are crossed, and the support 2, the sowing device body 3, the feeding pipe 4 and the sowing duckbill 401 are moved downward as a whole, so that the sowing duckbill 401 can be inserted into the soil after moving downward; then the driving motor 502 in the driving mechanism is used to work, and through the first sprocket 503, the chain 504, the second The sprocket 505, the rotating shaft 506 and the walking driven wheel 6 cooperate to drive the entire device to move to the right by rotating the walking driven wheel 6, and during the movement, the seeds are fed into the feeding tube 4 through the feeding port at the bottom of the seed storage chamber 301, and then the seeds are inserted into the soil through the sowing duckbill 401 for automatic sowing; at the same time, the fertilizer is fed into the feeding tube 4 through the feeding port at the bottom of the fertilizer storage chamber 302, and then the fertilizer is inserted into the soil through the sowing duckbill 401 for automatic fertilization; in this way, fertilization can be carried out while sowing, thereby achieving the purpose of supplementing fertilizer during the sowing process, which is beneficial to improving the survival rate of seeds after sowing and greatly improving work efficiency.
