[0002] Agricultural machinery refers to various mechanical equipment and tools used in agricultural production. They include mechanical equipment used in various links such as tillage, sowing, fertilization, irrigation, harvesting, processing and transportation. The development and application of agricultural machinery can improve agricultural production efficiency, reduce farmers' physical labor, improve agricultural production conditions and promote agricultural modernization.

[0003] With the continuous development of agricultural science and technology, seeding machines, as an important part of agricultural machinery, play an increasingly important role in improving planting efficiency and improving planting quality. The existing seeding machines have a single function during sowing and can only sow seeds. Before and after sowing, they still need to rely on manpower to dig trenches and cover the soil, which has high work intensity. Therefore, we propose an integrated seeding device. Utility Model Content

[0004] The utility model aims to provide an integrated sowing device which has the functions of automatic furrowing and soil covering to achieve the effect of reducing work intensity.

[0006] By adopting the above technical solution, before sowing, the rotary tillage mechanism turns the soil to be relatively soft, and then the furrowing mechanism is used to open furrows, and then the driving mechanism is started to drive the sowing mechanism to rotate, and the seeds in the sowing bucket are sown. While the U-shaped shell moves forward, the covering mechanism can cover the sown seeds with soil, thereby completing the sowing. The entire equipment integrates furrowing, sowing and covering, and has integrated sowing, high sowing efficiency, and is conducive to reducing the workload of operators.

[0007] The utility model is further configured as follows: the interior of the seeding bucket is hollow, the top and the bottom of the inner wall are both open, and the top of the seeding bucket is in a flared shape.

[0008] By adopting the above technical solution, the flared design makes it convenient to add seeds into the seeding bucket, and the top and bottom openings make it convenient for seeds to enter and exit.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-4 The utility model provides an integrated sowing device, including a U-shaped shell 1, a walking wheel 2 installed on the U-shaped shell 1, a sowing bucket 3 penetrating the inner top wall of the U-shaped shell 1, a sowing mechanism movably connected in the sowing bucket 3, and a driving mechanism installed on the U-shaped shell 1 for driving the sowing mechanism to rotate. The inner side of the U-shaped shell 1 is provided with a rotary tillage mechanism, a furrowing mechanism and a soil covering mechanism from left to right.

[0036] Before sowing, the rotary tillage mechanism turns the soil until it is relatively soft, and then uses the furrowing mechanism to dig furrows. The driving mechanism is then started to drive the sowing mechanism to rotate, and the seeds in the sowing bucket 3 are sown. While the U-shaped shell 1 moves forward, the covering mechanism can cover the sown seeds with soil, thereby completing the sowing. The entire equipment integrates furrowing, sowing and covering, and has integrated sowing, high sowing efficiency, and is beneficial to reducing the workload of operators.

[0037] The interior of the seeding bucket 3 is hollow and the top and bottom of the inner wall are both open.

The stepper motor 6 is started and drives the pulley 7 to rotate. The pulley 7 synchronously drives the sowing main shaft 4 to rotate. When the sowing main shaft 4 rotates, it drives the rotating scraper 5 to rotate to achieve seed sowing.
