Description
Technical Field
[0001] This utility model relates to the field of seeder technology, and in particular to a foldable seeder frame structure. Background Technology
[0002] With the improvement of agricultural mechanization, seeders have become key equipment in modern agricultural production. Among them, multi-film seeders, which can simultaneously complete the laying and sowing of multiple sets of films, have greatly improved work efficiency and are gradually replacing traditional single-film seeders. Patent No. CN220511632U discloses "a foldable multi-functional seeder". This seeder can lay three sets of films simultaneously through a foldable three-film support frame, and the support frame is folded by a hydraulic rod, reducing the floor space occupied when idle. It solves to some extent the problems of low efficiency of traditional single-film seeders and inconvenience of moving multi-film seeders.
[0003] However, in actual agricultural production, different crops have different planting requirements, and the spacing of the seed ridges to be sown varies. The seeders in the existing patents have fixed spacing between the film supports on both sides, which cannot be adjusted according to the spacing of the seed ridges. As a result, one seeder can only be adapted to a single spacing of seed ridges. If different spacing crops need to be planted, seeders of different specifications need to be replaced, which increases the equipment cost and operational complexity of agricultural production. Utility Model Content
[0004] This invention provides a foldable seeder frame structure, solving the problem mentioned in the background art that it is impossible to adjust the spacing according to the distance between the rows.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable seeder frame structure, including a central frame, an upright frame, side frames, and a first hydraulic pusher. The upright frame is fixed to the upper surface of the central frame. Two sets of side frames are symmetrically arranged on the left and right sides of the central frame. The first hydraulic pusher is connected between the upright frame and the side frames. One end of the first hydraulic pusher is hinged to the upright frame, and the other end of the first hydraulic pusher is hinged to the side frames. The upright frame hinged end of the first hydraulic pusher is higher than the side frame hinged end. Crossbars are fixedly connected to both sides of the upright frame. A sliding groove extending along the length direction is opened on the crossbar. A sliding rod is fixedly connected to the side frame. An insertion tube is provided at the free end of the sliding rod, and the insertion tube is slidably connected in the sliding groove.
[0006] Preferably, the free end of the slide rod has a through hole, and one end of the insertion tube protrudes from one side of the through hole and is inserted into the slide groove.
[0007] Preferably, a first connecting seat is fixedly connected to the upper surface of the side frame, the fixed end of the first hydraulic pusher is hinged to the upright frame, and the output end of the first hydraulic pusher is hinged to the side frame through the first connecting seat.
[0008] Preferably, the three sets of rear frames correspond one-to-one with the central frame and the side frames, and are respectively fixed to one side of the central frame and the side frames.
[0009] Preferably, the film-cutting assembly includes a film-cutting shovel and a second hydraulic pusher. A mounting frame is fixedly connected to the upper surface of the rear frame. The film-cutting shovel is rotatably connected inside the rear frame. A second connecting seat is fixedly connected to the upper inner side of the bucket of the film-cutting shovel. The fixed end of the second hydraulic pusher is hinged to the mounting frame, and the output end of the second hydraulic pusher is hinged to the film-cutting shovel through the second connecting seat.
[0010] Preferably, both the bottom of the central frame and the side frame are provided with a film coating assembly. Each film coating assembly includes a film coating cylinder and a pressing roller.

The film coating cylinder corresponding to the side frame is rotatably connected to the side frame, and the pressing roller corresponding to the side frame is rotatably connected to the side frame.
[0011] Preferably, the coating cylinder is located on one side of the pressing roller, and the coating cylinder is closer to the rear frame than the pressing roller, and the axis of the coating cylinder is parallel to the axis of the pressing roller.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. It enables flexible adjustment of the side frame spacing, which can be adapted to field operations with different spacing. It eliminates the need to replace multiple seeders, significantly reducing the cost of agricultural production equipment and improving equipment utilization. The hydraulic control system is easy to operate, and the spacing adjustment can be completed with simple operation, shortening equipment preparation time and improving operation efficiency.
[0013] 2. When not in use, the horizontal width of the rack can be reduced by adjusting the spacing between the side frames and folding the two side frames to save storage space. During the transfer process, it can easily pass through narrow roads and transport vehicles, reducing the difficulty of transfer and transportation costs, and improving the flexibility and mobility of the equipment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0017] This utility model provides a foldable seeder frame structure, such as... Figure 1 and Figure 2 As shown, the device includes a central frame 1, an upright frame 2, side frames 3, and a first hydraulic pusher 5. The upright frame 2 is fixed to the upper surface of the central frame 1. Two sets of side frames 3 are symmetrically arranged on the left and right sides of the central frame 1. The first hydraulic pusher 5 connects the upright frame 2 and the side frames 3. One end of the first hydraulic pusher 5 is hinged to the upright frame 2, and the other end is hinged to the side frames 3. A first connecting seat 4 is fixedly connected to the upper surface of the side frames 3. The fixed end of the first hydraulic pusher 5 is hinged to the upright frame 2, and the output end of the first hydraulic pusher 5 is hinged to the side frames 3 through the first connecting seat 4. The hinged end of the first hydraulic pusher 5 on the upright frame 2 is higher than the hinged end of the side frames 3. Horizontal bars 21 are fixedly connected to both sides of the upright frame 2. A sliding groove 211 extending along the length direction is opened on the horizontal bar 21. A sliding rod 31 is fixedly connected to the side frames 3. An insertion tube 32 is provided at the free end of the sliding rod 31 and is slidably connected in the sliding groove 211.
[0018] Preferably, the sliding groove 211 on the crossbar 21 has round ends. This round design can prevent the insertion tube 32 from getting stuck at the sliding end and at the same time provide a stable fulcrum for the rotation of the insertion tube 32 of the side frame 3.
[0019] like Figure 4 and Figure 5As shown, the free end of the slide rod 31 has a through hole 311, and one end of the insertion tube 32 protrudes from one side of the through hole 311 and is inserted into the slide groove 211.
[0020] like Figure 3 As shown, the three sets of rear frames 6 correspond one-to-one with the central frame 1 and the side frames 3, and are fixed to one side of the central frame 1 and the side frames 3 respectively. The film-cutting assembly includes a film-cutting shovel 7 and a second hydraulic pusher 8. A mounting frame 61 is fixedly connected to the upper surface of the rear frame 6. The film-cutting shovel 7 is rotatably connected to the inside of the rear frame 6. A second connecting seat 71 is fixedly connected to the upper inner side of the bucket of the film-cutting shovel 7. The fixed end of the second hydraulic pusher 8 is hinged to the mounting frame 61, and the output end of the second hydraulic pusher 8 is hinged to the film-cutting shovel 7 through the second connecting seat 71.
[0021] When the seeder completes the sowing and mulching operation on a section of the field ridge, the output shaft of the second hydraulic pusher 8 shortens, pulling the film-cutting shovel 7 downwards around the rotating shaft via the second connecting seat 71. The blade of the film-cutting shovel 7 gradually contacts the surface of the mulch film, cutting it. At the same time, the arc-shaped bucket of the film-cutting shovel 7 presses the cut edge of the mulch film into the soil to prevent it from curling up. After the film cutting is completed, the output shaft of the second hydraulic pusher 8 extends, pulling the film-cutting shovel 7 upwards and returning it to its initial retracted state.
[0022] like Figure 5 As shown, both the central frame 1 and the side frames 3 are equipped with film covering components 9 at their bottoms. Each film covering component 9 includes a film covering cylinder 92 and a pressing roller 91. The film covering cylinder 92 corresponding to the central frame 1 is rotatably connected to the central frame 1, and the pressing roller 91 corresponding to the central frame 1 is also rotatably connected to the central frame 1. The film covering cylinder 92 corresponding to the side frame 3 is rotatably connected to the side frame 3, and the pressing roller 91 corresponding to the side frame 3 is also rotatably connected to the side frame 3. The film covering cylinder 92 is located on one side of the pressing roller 91, and is closer to the rear frame 6 than the pressing roller 91. The axis of the film covering cylinder 92 is parallel to the axis of the pressing roller 91. The pressing roller 91 first compacts the surface of the ridges, and the film covering cylinder 92 releases the film as the device moves, directly covering the surface of the ridges after it has been compacted by the pressing roller 91.
[0023] Using this utility model, such as Figure 1 and Figure 2As shown, initially, the insertion tube 32 is located at the circular end of the slide groove 211 near the central frame 1, the slide rod 31 is inclined relative to the crossbar 21, and the side frame 3 is folded upward, significantly reducing the overall footprint of the equipment. When the equipment needs to enter the working state, the first hydraulic pusher 5 is activated, controlling its output shaft to slowly extend. Since the insertion tube 32 is located at the circular end of the slide groove 211 near the central frame 1 in the initial state, and this circular end provides a stable rotation fulcrum for the slide rod 31, the slide rod 31 rotates around the insertion tube 32 as the pivot, causing the folded side frame 3 to gradually unfold downward. During this process, the output shaft of the first hydraulic pusher 5 continuously applies force, and the angle between the side frame 3 and the horizontal direction gradually decreases until the side frame 3 is completely flat. At this time, the slide rod 31 and the crossbar 21 are horizontal, and the insertion tube 32 is still temporarily stationary at the circular end of the slide groove 211 near the central frame 1.
[0024] After the side frames 3 are laid flat, if it is necessary to adjust the distance between the side frames 3 and the central frame 1 according to the actual spacing of the ridges to be sown, the output shaft of the first hydraulic pusher 5 can be extended. As the output shaft of the first hydraulic pusher 5 extends further, its thrust direction changes from "pushing the side frames 3 to rotate" to "pushing the insertion tube 32 to move horizontally". Since the insertion tube 32 and the slide groove 211 are in sliding fit, and the slide groove 211 extends along the length of the crossbar 21, the insertion tube 32 will slide from the circular end of the slide groove 211 near the central frame 1 to the circular end away from the central frame 1, simultaneously driving the slide bar 31 and the side frames 3 to move horizontally away from the central frame 1. The operator can set the extension of the output shaft of the first hydraulic pusher 5 according to the preset value of the ridge spacing. When the output shaft extends to the preset length, the first hydraulic pusher 5 automatically triggers the hydraulic locking function to keep the output shaft at a fixed length. At this time, the insertion tube 32 is stably stopped at the corresponding position of the slide 211. The distance between the side frame 3 and the center frame 1 matches the ridge spacing. After the side frame 3 completes the fixed distance adjustment, the equipment enters the sowing operation stage.
[0025] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
