Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a seeder. Background Technology

[0002] In arid regions, drip irrigation under mulch film is widely used for sowing operations due to its water-saving and high-efficiency advantages. It requires a drip tape laying device to precisely lay the drip tape in the furrows under the mulch film, while a straightener prevents the drip tape from twisting, and a furrow opener opens the furrows to accommodate the drip tape. The drip tape laying device usually needs to be assembled with the seeder frame and must avoid the compaction rollers used for soil compaction.

[0003] When installing a drip irrigation tape laying device, it is often installed directly on the front crossbeam of the seeder using a diagonal bar. However, this structure is only suitable for scenarios where the diameter of the press roller is small or the front crossbeam is relatively far behind the press roller. When the diameter of the press roller is large and the crossbeam is far in front, the drip irrigation tape laying device will interfere with the press roller.

[0004] In order to accommodate large-diameter press rollers, another structure has emerged in the prior art. This structure requires an additional crossbeam behind the front crossbeam as a mounting rod to avoid the press rollers, but this results in the extension of the left and right longitudinal beams and other components on the longitudinal beams having to be moved back, thus taking up installation space. Utility Model Content

[0005] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model provides a seeder that has the advantages of being adaptable to large-diameter pressure rollers and having a compact structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A seeder includes a frame, a drip irrigation tape laying device, and a press roller. The frame includes a front crossbeam, and the press roller is rotatably mounted on the frame. The drip irrigation tape laying device is mounted on the front crossbeam via a mounting structure. The mounting structure includes a mounting tube, one end of which is connected to the front crossbeam, and the other end extends toward the press roller and is connected to the drip irrigation tape laying device. The extension trajectory of the mounting tube is adapted to the outer circumferential contour of the press roller to avoid the press roller.

[0007] In this application, the front crossbeam of the frame is used to install the drip irrigation tape laying device. The compaction roller is rotatably mounted on the frame and located near the front crossbeam for compacting the soil after sowing. The mounting structure includes a mounting pipe, one end of which is directly connected to the front crossbeam, and the other end extends towards the compaction roller and connects to the drip irrigation tape laying device. The extension trajectory of the mounting pipe is adapted to the outer circumference of the compaction roller, achieving the purpose of avoiding the compaction roller and adapting to large-diameter compaction rollers. Furthermore, one end of the mounting pipe is fixed to the front crossbeam. When the diameter of the compaction roller is large and the front crossbeam is relatively forward, there is no need to add an additional crossbeam as a mounting rod as in the prior art, which would cause the installation positions of other components on the left and right longitudinal beams to shift backward, making the seeder structure more compact.

[0008] Optionally, the installation pipe includes a first straight section, an arc-shaped section, and a second straight section connected in sequence. The first straight section is located near the front crossbeam, and the second straight section is located near the drip irrigation tape laying device.

[0009] The first straight section is located at the end of the installation pipe near the front crossbeam, and is entirely straight. Its straight structure facilitates docking with load-bearing components such as the front crossbeam. The curved section connects the first and second straight sections, and its contour adapts to the outer curvature of the pressure roller, thus avoiding space occupation by the pressure roller during the extension of the installation pipe. The second straight section is located at the end of the installation pipe near the drip irrigation tape laying device, facilitating the installation and positioning of the drip irrigation tape laying device.

[0010] Optionally, the axis of the first straight segment is perpendicular to the axis of the second straight segment.

[0011] The front crossbeam is arranged laterally along the frame. The axis of the first straight section extends longitudinally along the front crossbeam (perpendicular to the length direction of the front crossbeam), while the second straight section, which is perpendicular to the first straight section, points vertically toward the ground, so that the drip irrigation tape laying device can operate close to the ground without additional bending or connecting parts.

[0012] Optionally, the mounting structure includes a fixing seat, which is installed at one end of the mounting tube near the front crossbeam; the fixing seat includes a back plate and a clamp disposed on opposite sides of the mounting tube, the clamp engaging with the front crossbeam and fixed to the back plate and the mounting tube.

[0013] The backplate is located on one side of the mounting tube, and its area is adapted to the side wall of the mounting tube. The clamp is located on the opposite side of the mounting tube, and its inner contour matches the cross-sectional shape of the front crossbeam (such as square or round), and can be directly clamped to the outer periphery of the front crossbeam. By means of fasteners such as bolts and nuts, the clamp is passed through the mounting tube in sequence and fixed to the backplate, forming a double clamping force on the mounting tube and locking the fixing seat and the front crossbeam into one unit.

[0014] Optionally, the mounting tube is constructed as a square tube, and the back plate is constructed as a C-shape, and the back plate includes a main board and a first side plate and a second side plate respectively joined to both sides of the main board. The main board, the first side plate and the second side plate are respectively attached to different side walls of the mounting tube to form a receiving space for accommodating the mounting tube.

[0015] The C-shaped backplate and the square installation tube form multiple contact surfaces, increasing the contact area. When the drip irrigation tape laying device is subjected to operational loads (such as its own weight or ground impact), the load can be evenly transferred to the backplate through the three contact surfaces, and then from the backplate to the clamps and front crossbeam, avoiding deformation of the installation tube or cracking of the backplate caused by local stress concentration.

[0016] Optionally, the backplate is integrally formed.

[0017] The backplate consists of a main board, a first side plate, and a second side plate, all three manufactured from a single substrate through a bending process, without any splicing welds or assembly seams. The main board serves as the central load-bearing surface, while the first and second side plates are vertically distributed on both sides of the main board, together forming a C-shaped receiving space to accommodate the square mounting tube. The bends in the one-piece molded backplate have a continuous transition structure, and the material fibers are not cut, thus enhancing the strength of the backplate.

[0018] Optionally, the clamp has a U-shaped structure and includes two connecting posts. The back plate has a connecting hole, and the connecting posts pass through the mounting tube and are fixed in the connecting hole.

[0019] The U-shaped clamp is roughly U-shaped, with two cylindrical connecting posts symmetrically arranged at the open end. The outer circumference of the connecting posts is machined with external threads, and the inner arc surface of the U-shaped clamp is adapted to the outer contour of the front crossbeam. The ends of the connecting posts pass through the back plate, and the parts that protrude from the back plate are fitted with fasteners to connect the back plate and the clamp.

[0020] Optionally, the mounting structure includes a mounting base for assembling the drip irrigation tape laying device, the mounting base being fixed to one end of the mounting pipe away from the front crossbeam.

[0021] The mounting base has pre-drilled mounting holes or slots corresponding to drip irrigation tape laying devices (such as straighteners, furrow openers, and reel supports) to ensure proper alignment and installation of the drip irrigation tape laying devices. The mounting base is fixed to the end of the installation pipe furthest from the front crossbeam, and can be connected by welding or bolts to ensure that the mounting base and installation pipe form a rigid whole.

[0022] Optionally, the mounting base includes a welding surface, which is welded and fixed to the side wall of the mounting tube.

[0023] Compared to spot welding or wire welding, surface-to-surface welding between the welding surface and the side wall of the installation pipe results in a larger welding area. When the drip irrigation tape laying device is subjected to operational loads (such as trenching resistance, vibration and impact), it can avoid local stress concentration and make the connection between the mounting base and the installation pipe more secure.

[0024] Optionally, the mounting base is constructed as a hollow structure.

[0025] The hollow structure's internal cavities or frame gaps provide space for the subsequent installation of drip tape laying devices. For example, parts of the drip tape laying device extend into the mounting base and are secured with fasteners. Additionally, the hollow mounting base is lighter and easier to assemble.

Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0030] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this patent. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0031] One existing method for installing drip irrigation tape laying devices involves directly mounting the device to the front crossbeam of the seeder using a diagonal brace. However, this structure is only suitable for scenarios with smaller diameter rollers or when the front crossbeam is positioned relatively far back from the rollers. When the rollers are larger in diameter and the crossbeam is positioned further forward, the drip irrigation tape laying device will interfere with the rollers. Another existing method involves adding an additional crossbeam behind the front crossbeam as a mounting rod to avoid the rollers. However, this results in the extension of the left and right longitudinal beams, forcing other components on the longitudinal beams to be moved further back, thus encroaching on the installation space. Therefore, this application proposes a seeder that can accommodate large-diameter rollers and has a compact structure.

[0032] Example: like Figure 1 and Figure 2 As shown, a seeder includes a frame 1, a drip irrigation tape laying device, and a press roller 3. The frame 1 includes a front crossbeam 11. The press roller 3 is rotatably mounted on the frame 1. The drip irrigation tape laying device is mounted on the front crossbeam 11 via a mounting structure 2. The mounting structure 2 includes a mounting pipe 21. One end of the mounting pipe 21 is connected to the front crossbeam 11, and the other end extends toward the press roller 3 and is connected to the drip irrigation tape laying device. The extension trajectory of the mounting pipe 21 is adapted to the outer circumferential contour of the press roller 3 to avoid the press roller 3.

[0033] In this embodiment, the front crossbeam 11 of the frame 1 is used to install the drip irrigation tape laying device. The compaction roller 3 is rotatably mounted on the frame 1 and located near the front crossbeam 11 for compacting the soil after sowing. The mounting structure 2 includes a mounting pipe 21, one end of which is directly connected to the front crossbeam 11, and the other end extends towards the compaction roller 3 and connects to the drip irrigation tape laying device. In this embodiment, the extension trajectory of the mounting pipe 21 is roughly arc-shaped to match the outer contour of the compaction roller 3, thereby avoiding the compaction roller 3. The extension trajectory of the mounting pipe 21 can be adapted according to the diameter of the compaction roller 3. When the compaction roller 3 has a large diameter, the arc of the mounting pipe 21 can be increased to avoid the compaction roller 3; when the compaction roller 3 has a small diameter, the arc of the mounting pipe 21 can be decreased. The drip irrigation tape laying device (corrector, furrow opener, etc.) is mounted on the end of the mounting pipe 21 away from the front crossbeam 11 and is arranged behind the compaction roller 3 along the extension direction of the mounting pipe 21.

[0034] In existing technologies, straight-rod mounting components, if connected to the front crossbeam 11 and extending towards the pressure roller 3, are prone to interference with the outer periphery of the large-diameter pressure roller 3. In this embodiment, however, the extension trajectory of the mounting tube 21 is adapted to the outer contour of the pressure roller 3 to avoid it. It should be noted that adaptation does not mean the mounting tube 21 is in close contact with the outer periphery of the pressure roller 3; a certain distance should be maintained between the pressure roller 3 and the mounting tube 21 to avoid interference with the rotation of the pressure roller 3. That is, the mounting tube 21 maintains a safe gap with the pressure roller 3 throughout its extension process, ensuring that the drip irrigation tape laying device can approach the working area (meeting the requirements of under-film drip irrigation laying) while avoiding collisions or friction with the rotating pressure roller 3, thus achieving compatibility and avoidance with pressure rollers 3 of different diameters (especially large diameters). In addition, the installation pipe 21 is directly connected to the front crossbeam 11 of the frame 1, eliminating the need to add additional installation crossbeams to the longitudinal beams or other locations of the frame 1. This limits the installation space of the drip irrigation tape laying device to the unused area near the front crossbeam 11, avoiding the occupation of the longitudinal beam space and causing other components to move backward. This makes the layout of each component on the frame 1 more concentrated and reduces redundant space, thereby achieving a compact overall structure.

[0035] The installation pipe 21 includes a first straight section 211, an arc section 212 and a second straight section connected in sequence. The first straight section 211 is located near the front crossbeam 11 and the second straight section is located near the drip irrigation tape laying device.

[0036] In this embodiment, the first straight segment 211 is located at the end of the mounting pipe 21 near the front crossbeam 11, and is generally straight. Its straight structure facilitates docking with load-bearing components such as the front crossbeam 11. The arc segment 212 connects the first straight segment 211 and the second straight segment, and its contour adapts to the outer circumference curvature of the pressure roller 3, which is used to avoid the space occupied by the pressure roller 3 during the extension of the mounting pipe 21. The second straight segment is located at the end of the mounting pipe 21 near the drip irrigation tape laying device, which facilitates the installation and positioning of the drip irrigation tape laying device. The rigid connection of the first straight segment 211 and the smooth transition of the arc segment 212 combine to make the stress distribution of the mounting pipe 21 more uniform when bearing the weight of the drip irrigation tape laying device and withstanding the vibration of operation, reducing the risk of local breakage and extending the service life. The arc segment 212 is used to solve the problem of avoiding the pressure roller 3, and its curvature can be flexibly adjusted to adapt to pressure rollers 3 of different diameters; the first straight segment 211 and the second straight segment are used for connection and assembly, without sacrificing connection strength or assembly accuracy due to avoidance requirements.

[0037] The axis of the first straight segment 211 is perpendicular to the axis of the second straight segment.

[0038] In this embodiment, the front crossbeam 11 is arranged transversely along the frame 1. The axis of the first straight section 211 extends longitudinally along the front crossbeam 11 (perpendicular to the length direction of the front crossbeam 11), and the second straight section, perpendicular to the first straight section 211, points vertically towards the ground, so that the drip irrigation tape laying device can operate close to the ground without additional bending or connecting parts. Moreover, the height of the front crossbeam 11 and the installation position of the press roller 3 vary between different models of seeders. The two vertical straight sections, combined with the curvature adjustment of the arc section 212, allow the mounting pipe 21 to maintain a stable connection between the first straight section 211 and the front crossbeam 11, and a stable connection between the second straight section and the drip irrigation tape laying device, while avoiding the press roller 3.

[0039] like Figure 2 and Figure 3 As shown, the mounting structure 2 includes a fixing seat 22, which is installed on one end of the mounting tube 21 near the front crossbeam 11. The fixing seat 22 includes a back plate 221 and a clamp 222 disposed on opposite sides of the mounting tube 21. The clamp 222 is engaged with the front crossbeam 11 and fixed to the back plate 221 and the mounting tube 21.

[0040] In this embodiment, the back plate 221 is disposed on one side of the mounting tube 21, and its area is adapted to the side wall of the mounting tube 21. The clamp 222 is disposed on the opposite side of the mounting tube 21, and its inner contour matches the cross-sectional shape (such as square or circular) of the front crossbeam 11, and can be directly clamped to the outer periphery of the front crossbeam 11. By means of fasteners such as bolts and nuts, the clamp 222 is sequentially passed through the mounting tube 21 and fixedly connected to the back plate 221, forming a double-sided clamping force on the mounting tube 21, and locking the fixing seat 22 and the front crossbeam 11 into one unit. The double-sided clamping of the back plate 221 and the clamp 222 makes the connection between the mounting tube 21 and the front crossbeam 11 more stable, and the vibration and impact force generated during operation can be quickly transmitted to the front crossbeam 11 through the back plate 221 and the clamp 222, reducing the vibration amplitude of the mounting tube 21.

[0041] The mounting tube 21 is a square tube, and the back plate 221 is C-shaped. The back plate 221 includes a main plate 2211 and a first side plate 2212 and a second side plate 2213 respectively attached to both sides of the main plate 2211. The main plate 2211, the first side plate 2212 and the second side plate 2213 are respectively attached to different side walls of the mounting tube 21 to form a receiving space for accommodating the mounting tube 21.

[0042] In this embodiment, the mounting tube 21 adopts a square cross-section design with four flat sidewalls. This design not only provides superior torsional and bending resistance compared to a circular tube, but also provides a contact reference surface for the back plate 221. The back plate 221 has a C-shaped bent structure, consisting of a main plate 2211 and a first side plate 2212 and a second side plate 2213 perpendicularly joined to both sides of the main plate 2211. The main plate 2211 serves as the bearing surface, while the first and second side plates 2212 and 2213 serve as lateral limiting surfaces. Together, they form an accommodating space with an opening facing the clamp 222. The cross-sectional dimensions of this space match those of the square mounting tube 21. After the square mounting tube 21 is inserted into the accommodating space of the C-shaped back plate 221, the main plate 2211 is in contact with one sidewall of the mounting tube 21, while the first and second side plates 2212 and 2213 are in contact with the other two sidewalls of the mounting tube 21, respectively. Compared to the line contact between the flat backplate 221 and the circular pipe in the prior art, the C-shaped backplate 221 forms multiple surface contacts with the square installation pipe 21, increasing the contact area. When the drip irrigation tape laying device bears operational loads (such as its own weight or ground impact), the load can be evenly transferred to the backplate 221 through the three contact surfaces, and then from the backplate 221 to the clamp 222 and the front crossbeam 11, avoiding deformation of the installation pipe 21 or cracking of the backplate 221 caused by local stress concentration.

[0043] The back panel 221 is constructed as a single piece.

[0044] In this embodiment, the backplate 221 is composed of a main board 2211, a first side plate 2212, and a second side plate 2213, all three being manufactured from a single substrate through a bending process, without any splicing welds or assembly seams. The main board 2211 serves as the central load-bearing surface, while the first side plate 2212 and the second side plate 2213 are vertically distributed on both sides of the main board 2211, together forming a C-shaped receiving space for accommodating the square mounting tube 21. The bending points of the integrally molded backplate 221 have a continuous transition structure, and the material fibers are not cut, thus improving the strength of the backplate 221.

[0045] The clamp 222 has a U-shaped structure and includes two connecting posts 2221. The back plate 221 has a connecting hole 2214. The connecting post 2221 passes through the mounting tube 21 and is fixed in the connecting hole 2214.

[0046] In this embodiment, the U-shaped clamp 222 is roughly U-shaped, with two cylindrical connecting posts 2221 symmetrically arranged at the open end. The connecting posts 2221 have external threads machined on their outer circumference, and the inner arc surface of the U-shaped clamp 222 matches the outer contour of the front crossbeam 11. The ends of the connecting posts 2221 pass through the back plate 221, and fasteners are fitted onto the portions protruding from the back plate 221 to connect the back plate 221 and the clamp 222. The C-shaped back plate 221 has two connecting holes 2214 matching the diameter of the connecting posts 2221, and the distance between the two connecting holes 2214 is consistent with the distance between the connecting posts 2221 of the U-shaped clamp 222. The mounting tube 21 has through holes at positions corresponding to the connecting posts 2221, with a diameter slightly larger than the diameter of the connecting posts 2221 to ensure that the connecting posts 2221 can pass through. Specifically, the U-shaped clamp 222 can wrap around the front crossbeam 11 from the outside, and its inner side cooperates with the mounting tube 21 to restrict the axial and radial displacement of the clamp 222 itself along the front crossbeam 11.

[0047] The mounting structure 2 includes a mounting base 23 for assembling a drip irrigation tape laying device, which is fixed to the end of the mounting pipe 21 away from the front crossbeam 11.

[0048] In this embodiment, the mounting base 23 has pre-drilled mounting holes or slots corresponding to the drip irrigation tape laying device (such as a straightener, furrow opener, or reel bracket) to ensure that the drip irrigation tape laying device can be installed in alignment. The mounting base 23 is fixed to the end of the mounting pipe 21 away from the front crossbeam 11, and can be connected by welding or bolts to ensure that the mounting base 23 and the mounting pipe 21 form a rigid whole. In addition, after the mounting base 23 is fixed to the end of the mounting pipe 21, it can make the working direction of the drip irrigation tape laying device coordinate with the avoidance trajectory (arc segment 212) of the mounting pipe 21, avoiding interference with the press roller 3.

[0049] Mounting base 23 includes a welding surface 231, which is welded and fixed to the side wall of mounting tube 21.

[0050] In this embodiment, compared to spot welding or wire welding, the surface contact welding between the welding surface 231 and the side wall of the installation pipe 21 results in a larger welding surface area. When the drip irrigation tape laying device is subjected to operational loads (such as trenching resistance, vibration and impact), it can avoid local stress concentration and make the connection between the mounting base 23 and the installation pipe 21 more secure.

[0051] Mounting base 23 has a hollow structure.

[0052] In this embodiment, the internal cavity or frame gap of the hollow structure provides space for the subsequent installation of the drip irrigation tape laying device. For example, part of the drip irrigation tape laying device extends into the mounting base 23 and is secured with fasteners. In addition, the hollow mounting base 23 is lighter and easier to assemble.

[0053] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
