When the spade is used for sowing in the manual sowing, the sowing depth is determined according to experience and eye force, the depths of different people are different, and when the sowing is too deep, slow seedling emergence, uneven seedling emergence and weak secondary roots are caused; when the seeding is too shallow, the seedling is not drought-enduring, and is easy to freeze and die in early spring, so that the workload of later reseeding and management and protection is increased, and the labor, material and financial resources are wasted.

Specifically, the depth adjustment plate 071 has one end connected to the fixed lip 031 and the other end extending in a direction away from the conduit 01; by using the seeder provided by the embodiment of the invention to sow, the seed gun 03 is inserted into the soil, the depth adjusting plate 071 can be abutted with the surface of the soil, and the seed gun 03 is prevented from continuously moving into the soil, so that the sowing depth is kept consistent, the sowing depth is convenient to control, and the improvement of the sowing emergence rate is facilitated.

Through the depth adjustment plate 071, the scientific and unified seeding depth can be realized, the seeding depth is quantitatively controlled, and the defects of uneven seedling emergence, poor drought resistance and the like caused by different seeding depths are avoided.

Further, the depth adjustment plate 071 is slidably connected to the fixed lip 031 and is movable along the length direction of the guide pipe 01 with respect to the fixed lip 031.

Specifically, referring to fig. 7, an adjusting plate sliding groove 0311 is provided on the fixed lip 031; the depth adjusting plate 071 is fixedly connected with a sliding bending part 0711, the sliding bending part 0711 is provided with a through hole which is aligned with the adjusting plate sliding groove 0311, and the elastic screw 072 passes through the through hole and the adjusting plate sliding groove 0311; the tightness screw 072 can drive the depth adjustment plate 071 to move along the adjustment plate sliding groove 0311, and can lock the depth adjustment plate 071 on the fixed lip 031.

Further, a foot pedal 08 is connected to the end of the guide tube 01 close to the seed gun 03.

Specifically, the pedal 08 is welded on the outer wall of the guide pipe 01 and is close to the seed gun 03, and the seed gun 03 can be driven to be inserted into the soil by stepping the pedal 08, so that the seed gun 03 is more convenient to obtain larger driving force, and the seeder provided by the embodiment of the invention is easier to operate.

The seeder provided by the embodiment of the invention is used for seeding, so that seeds can be buried in soil by manpower; the outer diameter of the catheter 01 can be set to be 4cm-6cm, so that the catheter is convenient to carry and operate, and can be flexibly applied to various sowing areas.

Finally, it should be noted that: in the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described by differences from other embodiments, and identical and similar parts between the embodiments are only required to be seen with each other; the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
