Embodiment 1

[0024] Such as Figure 1~4 A double-roller support ditching sowing and earth covering device shown includes a liftable seeding frame 8, on which a seeding box 7 with an accommodating cavity is fixedly connected, and the bottom of the seeding box 7 is arranged in the length direction. The seed metering device 16, the seed drop port 17 of the seed meter device 16 faces the ground, the seed drop port 17 communicates with the housing cavity, the front part of the seed frame 8 is rotatably connected with the support roller 1, and the rear part of the seed frame 8 is rotatable Ground is connected with supporting pressing roller 9, and seed box 7 is between supporting roller 1 and supporting pressing roller 9, and is rotatably connected with ditching shaft 11 on the sowing rack 8 between seeding box 7 and supporting roller 1, and ditching shaft 11 is arranged with some ditching knife groups 12, and two ditching knives 14 are arranged on the same radial direction of the ditching shaft...

Embodiment 2

[0034] Such as Figure 5~7 A kind of double-roller support ditching sowing and soil covering device shown, the difference between this embodiment and embodiment 1 is that the seed drop openings 17 of the seed metering device 16 are set in the axial direction of the ditching shaft 11 corresponding one by one. There are two ditching knives 14 that are arranged oppositely, and the opposite sides of the two ditching knives 14 that are arranged oppositely are tangent. The corresponding earth covering knife 10 of the rear is arranged on the both sides outwards of ditching knife group 12 (as Figure 6 or Figure 7 shown); this embodiment realizes wide-band sowing, and the width of sowing is 5-10 cm; this embodiment can be applied to the work of opening shallow furrows and having a large sowing width.

Abstract

The invention discloses a double roller supported device for ditch digging, sowing and soil covering in the technical field of agricultural machinery. The double roller supported device comprises a lifting sowing frame, wherein a sowing box is fixedly connected with the sowing frame, a plurality of seed discharging devices are arranged at the bottom of the sowing box, and seed outlets of the seeddischarging devices are formed towards the ground; a support roller and a support pressing roller are rotatably connected to the sowing frame, the sowing box is arranged between the support roller andthe support pressing roller, and a ditch digging shaft is rotatably connected with the part, between the sowing box and the support roller, of the sowing frame; a plurality of ditch digging knife sets are arranged on the ditch digging shaft, at least one ditch digging knife is arranged in each radial direction of the ditch digging shaft, and a soil covering shaft is rotatably connected with the part, between the sowing box and the support pressing roller, of the sowing frame; a plurality of soil covering knives are arranged on the soil covering shaft. According to the double roller supporteddevice for ditch digging, sowing and soil covering, accurate seed falling can be achieved, and deep sowing is ensured.

Description

technical field [0001] The invention relates to a seeder, in particular to a seeder used for sowing shallow furrows. Background technique [0002] At present, mechanical operation has been widely realized for crop sowing, and ditching is carried out before sowing. In the prior art, there are 2 ways to realize ditching and sowing. The first one is to ditch the field to be sown, Sowing on the ground, for sowing on the field where the shallow ditch has been opened, the depth of the shallow ditch is 1-3cm. The sowing device includes a seeding box, which is fixedly connected to the walking device. The seeds fall on the field along the sowing pipe; the second is that the sowing device, including the sowing pipe, will shake under the interference of the external environment. Since the depth of the ditch is very shallow, as long as the sowing pipe is slightly disturbed, the sowing The height will change, and the seeds falling in the sowing tube cannot fall into the shallow ditch, a...
