Description

Technical Field

[0001] The utility model relates to a drag-type ditching, seeding and rolling integrated no-till seeder, which belongs to an agricultural seeding machine, and particularly relates to an integrated no-till seeder with functions of tilling and ditching, sowing seeds and rolling ridges and furrows. Background Art

[0002] A no-till seeder is a machine for sowing seeds on stubble fields without tillage, also known as a direct seeder. By improving the traditional tillage method, the no-till seeder realizes sowing while retaining crop residues, which helps to maintain soil moisture, reduce water evaporation, and thus improve the growth environment and yield of crops. In addition, the no-till seeder reduces soil tillage, reduces soil erosion and soil loss to improve seeding efficiency and crop yield. The use of no-till seeders also promotes the modernization and intensification of agricultural production, improves agricultural production efficiency and economic benefits, and is conducive to protecting the ecological environment and sustainable development.

[0003] Chinese Patent Publication No. CN114679938A discloses an invention patent named a no-till seeder for interplanting and multiple cropping between fixed channels. The no-till seeder for interplanting and multiple cropping between fixed channels includes a frame, a suspension device, a transmission device, a traveling device, a stubble-breaking device, and a seeding system. The suspension device is fixed above the frame, the stubble-breaking device and the traveling device are installed below the frame, the seeding system is installed behind the frame, and the stubble-breaking device and the seeding system are driven by the transmission device. The following technical problems will occur in the specific seeding application of the no-till seeder disclosed in the above patent.

[0004] In paragraph

[0019] of the specification, the seeding system includes a seeding unit suspension 3, a profiling device 4, a seed box 5, a side plate 6, a metering device 7, a furrow opener 8, a weed guide roller 9, and a rolling wheel 10. By reading the patent specification and the specification drawings, it can be seen that the seeding system of the no-till seeder for interplanting and multiple cropping between fixed channels only has a single set of rolling wheels. In the specific seeding process, there is only one rolling process after the ditching and seeding process. When sowing in dry spring or encountering dry cultivated land, the single set of rolling wheels cannot compact and flatten the floating soil in the furrow after seeding in the furrow under the state of one-time wheel pressure, which will affect the germination rate of crop seeds and cause a reduction in cultivated land production. When the surface of the cultivated land is uneven or the heights of the edges of the ridges and furrows are inconsistent, the single set of rolling wheels moves along the undulating curve with the uneven surface of the cultivated land. The rolling pressure of the rolling wheel on the highest points of the cultivated land surface and the furrow is greater than that on the lowest points of the cultivated land surface and the furrow, resulting in uneven rolling pressure on the soil in the uneven cultivated land and the furrow with uneven heights, and further resulting in intermittent seedling shortage in the cultivated land due to uneven germination of seeds in the furrow.

[0047] More specifically, as Figure 7As shown, the rotating connecting shaft 4d of the connecting frame body 4 includes a connecting shaft 4d1, a connecting seat 4d2, and a connecting fixing bolt 4d3. One end of the connecting shaft 4d1 is fixedly connected to the connecting seat 4d2.

[0051] The following further elaborates on the ditching, seeding, and rolling working process of a kind of drag-type ditching, seeding, and rolling integrated no-till seeding machine of the present utility model in farmland cultivation in combination with the attached drawings and specific embodiments.

[0052] Referring to Figure 1 Figure 2 Figure 3 Figure 4As shown in the figure, the main frame body 1 of a drag-type ditching, seeding and rolling integrated no-till seeding machine of the present utility model is provided at the rear end of an agricultural power machine through a traction beam 1a, and a hydraulic component 5 is connected to a hydraulic output oil pipe of a hydraulic device of the agricultural power machine. When the no-till seeding machine is in a non-working state, the ditching and seeding component 2, the light rolling component 3 and the heavy rolling component 7 are all in a state of being lifted off the ground upward.

The agricultural power machine drives the no-till seeding machine to move forward for seeding operations, and at the same time, the ditching depth of the no-till seeding machine during seeding operations is adjusted through the hydraulic device of the agricultural power machine.

[0053] Reference Figure 1 Figure 2 Figure 3 Figure 4 As shown in the figure, when encountering large soil hardness or large soil clods in the cultivated land, the light rolling component cannot meet the rolling requirements for crop seeds in the ridges of the cultivated land. The hydraulic device of the agricultural power machine drives the hydraulic component 5 to move the second connecting beam 4a at the rear end of the connecting frame body 4 downward, and the heavy rolling component 7 provided on the second connecting beam 4a of the connecting frame body 4 is in full contact with the cultivated land surface to complete the secondary rolling operation of the no-till seeding machine.

[0054] In order to enhance the connection stability between the hydraulic component and the main frame body of a drag-type ditching, seeding and rolling integrated no-till seeding machine of the present utility model, improve the support stability between the hydraulic component and the main frame body, and maintain the control stability of the hydraulic component over the heavy rolling component, as Figure 2 Figure 3 shown in the figure, a support and fixation component 8 is further provided between the hydraulic component 5 and the main frame body 1.

[0055] Specifically, as shown in the figure 11, for a drag-type ditching, seeding and rolling integrated no-till seeding machine of the present utility model, the support and fixation component 8 is arranged between the hydraulic component 5 and the main frame body 1, and it includes a support and fixation plate 8a, a connecting and fixing clamp 8b and a connecting and supporting rod 8c.

[0056] As shown in the reference figure 11, the support and fixation component 8 is supported between the cross connecting rod 5b of the hydraulic component 5 and the main connecting beam 1b of the main frame body 1. The support and fixation component 8, the connecting and fixing plate 6a of the fixing and connecting component 6 and the longitudinal connecting rod 5c of the hydraulic component 5 form a stable triangle under the connection of the main connecting beam 1b of the main frame body 1 and the cross connecting rod 5b of the hydraulic component 5, and the support and fixation component 8 provides a stable supporting force for the hydraulic component 5.

[0057] As further specifically shown in FIG. 12, the connecting clamp 8b includes a flat connecting plate 8b1 and opposing clamping plates 8b2. The two opposing clamping plates 8b2 are fixedly connected to the outer end of the flat connecting plate 8b1, and the inner end of the flat connecting plate 8b1 is fixedly connected to the connecting support rod 8c. An inner concave structure 8a1 matching the cross-section of the main connecting beam 1b is provided on the outer side of the supporting and fixing plate 8a, and the supporting and fixing plate 8a is clamped and fixed on the main connecting beam 1b through its inner concave structure 8a1. The connecting clamp 8b is inserted and clamped inside the supporting and fixing plate 8a through its two opposing clamping plates 8b2 and is connected and fixed through a connecting bolt 8d.

[0058] In the forward movement during the sowing operation of a drag-type ditching, sowing, and rolling integrated no-till seeder of the present utility model, the cultivated soil will generate a relatively large resistance to its ditching and sowing components. To further reduce these resistances, the ditching and sowing components and the light rolling components can be combined into a long body component and a short body component.

[0059] Specifically Figure 2 As shown, the sowing component 2 and the light rolling component 3 transversely connected in series on the first connecting beam 1c of the main frame body 1 are combined into a long body component A and a short body component B, and the long body component A and the short body component B are alternately transversely connected in series on the first connecting beam 1c of the main frame body 1. During the forward movement of the seeder when the long body component A and the short body component B are arranged front and back, the ditching and sowing component 2 advances alternately in the cultivated soil, which can effectively reduce the resistance generated by the cultivated soil to the ditching and sowing component.

[0060] As further specifically shown in FIG. 12, in the drag-type ditching, sowing, and rolling integrated no-till seeder of the present utility model, a first rolling wheel 7a and a second rolling wheel 7b are simultaneously provided on the heavy rolling component 7. The long body component A and the short body component B of the ditching and sowing component 2 respectively correspond to the first rolling unit 6a and the second rolling unit 6b of the heavy rolling component 7 front and back.

[0061] The above is a detailed introduction to a drag-type ditching, sowing, and rolling integrated no-till seeder provided by an embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the embodiment of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model, and any changes made according to the design idea of the present utility model are within the protection scope of the present utility model.
