Embodiment 1

[0029] Embodiment 1: as Figure 1-Figure 3 As shown, the present invention includes a frame, a rotary tillage and crushing device 1, a pressing roller 7, a soil covering conveying device, a shunting guide device 14 and a seed film coating device, and the rotary tilling and crushing device 1 and the suppressing roller are sequentially arranged below the frame 7. The seed film coating device, the rotary tillage and soil breaking device 1 is arranged under the frame at the front end of the work, and the soil is rotary cultivated; the seed film film coating device is set under the frame at the rear end of the work, and the shunt guide device 14 is set above the frame The covering soil conveying device is obliquely arranged on the frame between the rotary tillage and crushing device 1 and the seed film covering device, the soil after the rotary tillage and crushing device 1 is thrown to the covering soil conveying device, and the covering soil is dropped by the covering soil diversi...

Embodiment 2

[0038] Embodiment 2: The difference between this example and Embodiment 1 is that the transmission wheel in this example is a belt pulley, and the transmission parts are a plurality of belts arranged side by side, so that the rotary tillage and soil breaking device 1 is thrown on the transmission belt, and multiple belts are simultaneously transported The soil is delivered to the diversion guide device 14, and falls after diversion. The angle α between the soil-covering conveyor belt and the horizontal plane is 65°. The included angle β between the diversion groove and the horizontal plane is 80°. The included angle γ between the bottom edge and the side edge of the grooved belt of the pressing roller is 90 degrees, and the height of the boss is 60 mm. The height difference H0 between the mounting bottom surface of the pressing roller and the bottom surface of the rotating shaft of the rotary tillage and soil breaking device is 55mm.

Embodiment 3

[0039] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the transmission wheel in this embodiment is a belt pulley, and the transmission member is formed by a plurality of conveyor chains arranged side by side, and its working principle is the same as that of Embodiment 2; The included angle α is 50°. The included angle β between the diversion groove and the horizontal plane is 60°. The included angle γ between the bottom edge and the side edge of the grooved belt of the pressing roller is 45 degrees, and the height of the boss is 30mm. The height difference H0 between the mounting bottom surface of the pressing roller and the bottom surface of the rotating shaft of the rotary tillage and soil breaking device is 45mm.

Abstract

The invention provides a rice-seed-film-mulching and direct-sowing machine and belongs to the technical field of agricultural machines. The machine includes a machine frame, a rotary tillage soil crushing device, a press roller, a covering soil transmission device, a shunt guiding device and a seed film mulching device; the rotary tillage soil crushing device, the press roller and the seed film mulching device are arranged below the machine frame in sequence, and the rotary tillage soil crushing device is arranged below the working front end of the machine frame and used for rotary tillage of soil; the seed film mulching device is arranged below the working rear end of the machine frame, the shunt guiding device is arranged above the machine frame, the covering soil transmission device is obliquely arranged on the portion, located between the rotary tillage soil crushing device and the seed film mulching device, of the machine frame, and after rotary tillage is conducted by the rotary tillage soil crushing device, the soil is thrown to the covering soil transmission device and falls off from a mulching film through the covering soil shunt guiding device; the press roller is located below the covering soil transmission device; when the machine is in work, a film press roller of the seed film mulching device presses against the seed film, and the soil falling off through the covering soil shunt guiding device covers a seed belt of the seed film. The machine eliminates the phenomenon of seed film hanging, soil covering is centralizedly and evenly conducted, and the seedling emergence rate and the grain yield are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a rice seed film-covering direct seeding machine. Background technique [0002] Dry direct seeding of rice is a production mode of light and simple rice cultivation, which greatly reduces production costs and labor because it omits the traditional operations of rice seedling raising and transplanting. However, the problem of weed control in dry direct seeding of rice has been well solved, which affects the yield of rice. At the same time, due to the application of a large amount of herbicides to control weeds, it poses a hazard to food security, sustainable agricultural development and the environment. Film-covered direct seeding cultivation of rice is to stick the rice seeds to the degradable seed film with a special adhesive, cover the seed film on the ground (the seeds are in contact with the soil under the film), and use the degradable seed film to ...
