[0031] A rear frame 13 is arranged at the rear side of the crawler frame, and a spare structure IX, a seed sowing structure X, a fertilizer spreading structure XI and a rear structure IV are arranged on the rear frame 13 in sequence. The rear structure IV is located on the side of the fertilizer spreading structure XI away from the crawler frame.

[0032] The seed sowing structure X and the fertilizer spreading structure XI both include a storage chamber 17, a distributor 19 connected to the discharge port of the storage chamber 17, a distributor driving structure, a guide pipe 16 connected to the discharge port of the distributor 19, and a conical rake 14 arranged in front of the discharge port of the guide pipe 16. The conical rakes 14 on both the seed sowing structure X and the fertilizer spreading structure XI are in a staggered state.

[0033] The conical rake 14 is a conical structure. The upper part of the conical rake 14 is fixed on the connecting rod 15. The upper part has a guiding inclined mechanism for placing soil and the like upward. It is placed in front of the guide pipe and is used to rake up soft soil, fertilizer, etc. At the same time, the material in the front can be further separated and crushed. At the same time, the rear can be ensured to be open without soil and the like covering it, so that it can slide through the guide pipe from the upper part through the seed distributor to reach the soil in the lower part. Multiple conical rakes are arranged in parallel to realize the distribution and placement of seeds. The conical rakes in parallel in the front row are used to open up the soil space for seed sowing, and the conical rakes in parallel in the rear are used to open up the space for fertilizer and the like sowing. The conical rakes with spacing in front and back usually ensure that the fertilizer will not be directly sown on the seeds, ensuring the healthy growth of the seeds. The connecting rod 15 is connected to the rear frame 13, and the bottom end of the guide pipe 16 is connected to the connecting rod 15.

[0034] The storage chamber 17 has an openable upper cover, and a discharge port is provided on one side of the bottom of the inner cavity of the storage chamber 17.

When the device is in use, the push plate 18 can be used to push the seeds or fertilizers in the storage chamber 17 to the discharge port of the storage chamber 17, so as to realize the continuous falling of the materials in the storage chamber 17. The materials fall into the distributor 19 under the action of gravity, and the distributor 19 distributes the materials to the corresponding guide tubes 16. The materials are discharged along the guide tubes 16, so as to realize the guided sowing of fertilizers or seeds to a precise position. When placing fertilizers or seeds, the push plate 18 pushes the spring to the inner wall of the storage chamber 17, and then the fertilizers or seeds are placed.

[0035] The distributor 19 is a seed or fertilizer distributor. The distributor is an existing mature product and will not be described in detail here.

The upper part of the roller is rotatably connected with a connecting rod and a gas spring rod 10. The gas spring rod 10 can ensure that the roller jumps with the uneven ground and moves in contact with the ground without slipping.

[0036] The rear structure IV includes a scraper 12 and a cylinder 11 connected to a rear frame 13. The end of the output shaft of the cylinder 11 is connected to the scraper 12.

The scraper 12 is made of soft material and is installed on a connecting block by bolts. The connecting block is movably connected to the rear frame 13 by a connecting rod. The scraper 12 can be used to backfill and level the soil processed by the machine to achieve the purpose of burying seeds, etc.

[0037] The other end of the cylinder 11 is connected to the rear frame 13 through a screw structure. The screw structure includes a ball screw movably connected to the rear frame 13. The outer ring of the ball screw is threadedly connected to a ball nut. The cylinder 11 is fixedly connected to the ball nut, and the rear frame 13 is provided with a driving motor for driving the ball screw to realize automatic adjustment of the position of the cylinder 11.

[0038] The standby structure IX includes a standby storage chamber 20 and a tumbling wheel 21 arranged below the standby storage chamber 20.
