Referring to fig. 1, the multifunctional seeding device includes a seed box 1 with a hollow structure, a discharge hopper 2 fixed at the bottom of the seed box 1 and having a seed discharge port 21, a seeding assembly rotatably disposed in the seed box 1 for discharging seeds, wherein the seeds enter an inner cavity from a top opening of the seed box 1, the seeding assembly is in transmission connection with an external motor (not shown in the figure), and the external motor drives the seeding assembly to rotate, so that the seeds are orderly discharged when the seeding assembly rotates, enter the hopper 2, and are discharged into soil from the seed discharge port 21 at the bottom of the discharge hopper 2, so as to realize orderly seeding.

In this embodiment, the seed box 1 includes a housing 1a and a back plate 1b fixed on the side of the housing 1a, a V-shaped opening is formed at the top of the seed box 1, an inner cavity of the seed box is divided into a first seeding chamber 11 located at one side and a second seeding chamber 12 located at the other side by a substantially longitudinally extending partition 15, the top ends of the two seeding chambers are located at the V-shaped opening to form a first feeding port 11a and a second feeding port 12a, different seeding assemblies are disposed in the two seeding chambers to be used for seeding different kinds of seeds respectively, and two cover plates 13 are slidably disposed on the seed box 1 from two sides to the middle along an oblique direction to realize opening and closing of the first feeding port 11a and the second feeding port 12a respectively. During sowing, the cover plate 13 at the top of one sowing chamber is pulled outwards according to the type of seeds, the seeds enter the corresponding sowing chamber from the feed inlet, the motor drives the sowing assembly to rotate so that the seeds fall down orderly, and the seeds are discharged into soil through the seed discharge opening 21 at the bottom of the discharge hopper 2, so that sowing is realized. By forming two sowing chambers in the seed box 1, the multifunctional seed box is realized, the types of seeds for sowing are increased, and the functionality is improved.

Referring to fig. 2 and 3, in the present embodiment, a seeding core 3 is rotatably installed in a first seeding chamber 11, the seeding core 3 is of a substantially cylindrical structure, a plurality of seed grooves 31 for accommodating seeds are uniformly distributed along the circumferential direction on the periphery of the seeding core 3, the seed grooves 31 extend along the axial direction of the seeding core 3, two ends of the seed grooves 31 form openings, one end of the seeding core 3 penetrates out from one side of the seed box 1, and a spline shaft 63 hole for connecting a motor transmission shaft is formed at the center position of the seeding core. The sowing core 3 is mainly used for sowing seeds with smaller particles such as wheat, and takes the wheat seeds as an example, when sowing, a cover plate 13 at the top of a first sowing chamber 11 is opened to enable a first feed inlet 11a to be opened, the wheat seeds enter the first sowing chamber 11 from the first feed inlet 11a, a certain interval is reserved between the periphery of the sowing core 3 and the inner wall of the first sowing chamber 11, a motor drives the sowing core 3 to rotate, a seed groove 31 on the surface of the sowing core drives the wheat seeds to move downwards, a pulling effect is achieved, and the wheat seeds are discharged downwards under the sowing effect when the sowing core 3 rotates, so that uniform sowing is achieved. As an example, the bottom of the first sowing chamber 11 is provided with an arc-shaped bottom plate 5, an opening for communicating the first sowing chamber 11 with the discharge hopper 2 is formed between the inner end of the arc-shaped bottom plate 5 and the partition 15, and in the stopped state, the wheat seeds enter the first sowing chamber 11 along the 01 direction and are supported on the arc-shaped bottom plate 5, and cannot actively enter the discharge hopper 2 through the opening. When the sowing core 3 rotates, the seeds are driven to advance towards the opening at the end part of the arc-shaped bottom plate 5, so that the seeds fall.

As an example, one end of the arc-shaped bottom plate 5 is rotatably connected with the seed box 1, and the opening size formed between the arc-shaped bottom plate 5 and the partition portion 15 is changed by rotation adjustment of the arc-shaped bottom plate 5, so that the seed dropping flow rate is adjusted.

The spline shaft 63 is rotationally connected with the seed box 1, the spline shaft 63 is fixed at any angle, a spline shaft hole in the center of the brush holder 61 is in plug-in fit with the spline shaft 63, so that the spline shaft 63 and the brush holder 61 can be driven to rotate together when the handle 64 is rotated from the outside, and a row of bristles 62 fixed on the brush holder 61 can be rotated around the axis of the spline shaft 63, so that the distance between the bristles 62 and the sowing core 3 can be adjusted. When the brush hair 62 rotates and adjusts to the position contacting with the periphery of the sowing core 3, the brush hair 62 sweeps the seeds in the discharging process, thereby avoiding the mutual adhesion between the small particle seeds and further improving the discharging uniformity. When the brush hair 62 rotates and adjusts to be close to the inner wall of the seed box 1, seeds can not pass through the sweeping operation of the brush during blanking, and then the brush is selectively used according to different seeds, so that the practicability is improved.

Referring to fig. 4, in this embodiment, the device further includes a limiting plate 65 for limiting the rotation range of the handle 64 and axially limiting the handle 64, wherein the limiting plate 65 is in an arc-shaped sheet structure, two ends of the limiting plate 65 are fixed on the seed box 1 through a bolt lock, the handle 64 passes through a limiting space between the limiting plate 65 and the seed box 1, the handle 64 can only rotate within a limited range of two ends of the limiting plate 65, and meanwhile, the inner ends of the limiting plate 65 are pressed against the handle 64, so that the handle 64 and the flower-shaped shaft are axially fixed. Thereby facilitating replacement of the brush, i.e., the handle 61 and bristles 62. For example, when the brush is replaced, the bolts at the two ends of the limiting piece 65 are removed and the limiting piece 65 is removed, the handle 64 and the spline shaft 63 are drawn out of the seed box 1 together, the spline shaft 63 is separated from the brush, the brush is taken out from the first feed inlet 11a at the top of the first seeding chamber 11, and when the brush is installed, the reverse operation of the above process is realized, and the description is omitted here. Through above-mentioned setting, be convenient for to the change of brush, convenient to use.
