[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0034] like Figures 1 to 4 As shown, a drum-type multi-row sowing device of the present embodiment comprises a frame 1, rolling wheels 2 are respectively arranged on both sides of the middle part of the frame 1, a horizontally arranged rotating shaft 3 and a plurality of seed bins 4 rotating with the rotating shaft 3 are arranged at the rear part of the frame 1, the rolling wheels 2 are connected to the rotating shaft 3 by a chain drive, a plurality of sowing holes 41 are arranged on a vertical plane in the middle part of the seed bin 4, a hopper 5 is arranged below each of the seed bins 4, a guide tube 51 for guiding the seeds to fall is arranged below the hopper 5, and the hopper 5 is fixedly connected to the frame 1.

[0035] When sowing, the rolling wheel 2 falls on the ground, and when the frame 1 moves forward under the action of the tractor, the rolling wheel 2 rolls under the action of the ground friction, thereby driving the seed bin 4 to rotate, and the seeds in the seed bin 4 fall from the sowing hole 41 through the guide pipe 51 of the hopper 5 and fall into the field. The spacing of the seeds is strictly in accordance with the rolling speed of the rolling wheel 2, so the spacing is more accurate, and different spacing requirements can be controlled by adjusting the transmission ratio of the chain.

[0036] Further, the rotating shaft 3 is connected to the frame 1 through a bearing, the seed bin 4 is spherical or cylindrical, and a cover plate 42 for adding seeds that can be unscrewed is provided on the circumferential side of the seed bin 4. When the cover plate 42 is unscrewed, seeds can be added to the seed bin 4 from this position. In this embodiment, the seed bin 4 is spherical.

[0037] Furthermore, the frame 1 is provided with a furrowing device 6, and the furrowing device 6 is located in front of the seed bin 4. The furrowing device 6 is used to plow a furrow on the ground, and the seeds fall directly into the corresponding furrow.

[0038] Furthermore, the furrowing device 6 includes a connecting shaft 61, which is arranged in the horizontal direction. The connecting shaft 61 is provided with a plurality of rolling balls 62, the number of which is the same as the number of the seed bins 4, and a rolling ball 62 is provided in front of each seed bin 4. Both ends of the connecting shaft 61 are connected to the frame 1 through a connecting seat 63, and the connecting seat 63 is provided with a waist-shaped hole in the vertical direction. When the rolling wheel 2 rolls in the field, the bottom of the rolling ball 62 falls into the field. This embodiment is used for rice sowing. For other crops, the rolling ball 62 can also be replaced with a furrowing plow that can plow the land.

[0039] Furthermore, the present embodiment is also provided with a detachable tractor 7, which is provided with a tractor frame 71, a steering wheel 72, a driving wheel 73, a driving motor for driving the driving wheel 73 to rotate, and a steering motor for driving the steering wheel 72 to steer, and the front end of the frame 1 is connected to the tractor 7.

[0040] Furthermore, the frame 1 is provided with a traction part for connecting with the traction frame 71, and the traction part is provided with a lifting mechanism for lifting or lowering the frame 1. Specifically, the front end of the traction part is provided with a slide groove 11, and the slide groove 11 is in the shape of a waist-shaped hole. The traction frame 71 is provided with a hinge pin. The traction part is hinged with the hinge pin of the traction frame 71 through the slide groove 11, and the hinge pin can slide along the slide groove 11. The lifting mechanism includes a telescopic rod 8, one end of which is hinged with the traction frame 71, and the other end is fixedly connected with the frame 1 through a connecting rod 9. When driving on the road and turning around in the field, when the telescopic rod 8 is extended, the frame 1 as a whole rotates upward around the hinge part at the front end, thereby leaving the ground and stopping sowing. When sowing in the field, the telescopic rod 8 is shortened, the frame 1 rotates downward, and the rolling wheels contact the ground.

[0041] Furthermore, the tractor 7 is provided with three wheels, including a front steering wheel 72 and two rear driving wheels 73 .

[0042] The tractor 7 of this embodiment can be used alone, and the tractor 7 of this embodiment can be remotely controlled by providing communication equipment and a controller, without the need for manning, and the operator can perform remote control on the ridge. Specifically, this embodiment is provided with a remote controller, and the tractor 7 is provided with a microprocessor for controlling the drive motor, the steering motor, and the extension and retraction of the telescopic rod 8. The microprocessor is connected to the remote controller via a wireless signal, so that the forward, backward, steering, and lifting and lowering of the frame 1 of the tractor can be remotely controlled via the remote controller.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
