Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a four-link synchronous contour-following seed rope sowing mechanism. Background Technology

[0002] Seed rope sowing technology involves fixing seeds in a fixed posture and spacing within biodegradable packaging tape to create seed ropes, which are then sown into the soil. To improve sowing efficiency, existing technologies, such as the utility model patent CN219322912U, disclose a jujube seed rope sowing machine. This machine frame is equipped with a furrow opener for excavating the soil and a guide tube for guiding the seed ropes into the furrows. However, when operating on fields with relatively flat surfaces, the furrow opener's tilling depth varies, and the sowing process is bumpy, affecting the sowing quality. Utility Model Content

[0003] The purpose of this invention is to provide a four-link synchronous contour seed rope sowing mechanism, which solves the problem of poor sowing quality in the prior art and improves sowing quality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a four-bar linkage synchronous contour-following seed rope sowing mechanism, comprising a seed rope frame, a seed rope guide tube, an upper link, a lower link, a front link, and a rear link. The upper link and the lower link are parallel and their two ends are respectively hinged to the front link and the rear link to form a four-bar linkage mechanism. The seed rope guide tube is connected to the rear link, and a seed furrow opener is installed on the seed rope guide tube. The seed furrow opener is located in front of the seed rope guide tube.

[0005] After adopting the above technical solution, this utility model has the following advantages: The four-bar linkage can automatically adjust the height of the furrow opener according to the undulation of the ground, thereby maintaining a relatively constant tillage depth as much as possible, which helps to ensure that the seeds are planted at the set soil depth and improve the sowing quality. Since the four-bar linkage can adapt to terrain changes and maintain a stable working posture, it can effectively reduce the impact of the bumps on the sowing accuracy when the seed rope sowing mechanism is moving, further improve the sowing quality, reduce the need for manual intervention, improve the overall operation efficiency, and reduce labor intensity. The seed furrow opener is directly installed on the seed rope guide tube, without the need to set up other tubes to install the seed furrow opener. The seed rope guide tube has two uses, fewer parts, and a more compact structure.

[0006] Furthermore, a force-applying spring is provided between the upper connecting rod and the lower connecting rod, and the force-applying spring is inclined back and forth.

[0007] By employing the aforementioned technical solution, the presence of the force-adding spring provides additional elastic support, allowing the four-bar linkage mechanism to respond more flexibly to changes in ground conditions. When encountering undulating terrain, the force-adding spring can absorb some of the impact and help the system quickly return to the preset working posture, ensuring that the seed furrow opener maintains the set tillage depth as much as possible. The inclined setting of the force-adding spring helps enhance the stability of the seed rope sowing mechanism in the forward direction. When the seed rope sowing mechanism encounters obstacles or sudden changes in terrain, the force-adding spring not only provides cushioning in the vertical direction but also resists lateral swaying through the horizontal component of force provided by its inclined angle, thereby ensuring the stable operation of the seed rope guide tube and the seed furrow opener as much as possible.

[0008] Furthermore, at least two seed rope guide tubes are provided, and each seed rope guide tube is equipped with a seed furrow opener.

[0009] Using the aforementioned technical solution, multiple seed rope guide tubes can process multiple seed ropes simultaneously, which can significantly improve sowing speed and work efficiency.

[0010] Furthermore, the rear connecting rod is provided with a mounting seat for installing the seed rope guide tube. The mounting seat is provided with a mounting sleeve and a fixing bolt. The seed rope guide tube passes through the mounting sleeve and can be raised and lowered vertically. The fixing bolt passes through the mounting sleeve to press the seed rope guide tube tightly.

[0011] The ability of the seed rope guide tube to rise and fall vertically means that the sowing depth can be precisely adjusted according to actual needs, and the furrowing depth can also be adjusted so that the seeds can be planted at the target depth.

[0012] Furthermore, a fertilizer ditch opener is provided in front of the seed rope guide tube, and the fertilizer ditch opener is connected to the front connecting rod.

[0013] With the above technical solution, if the fertilizer ditch opener is located behind the seed rope guide tube, it may accidentally come into contact with the seed rope during the process, causing the seed rope to be cut or pulled. By positioning the fertilizer ditch opener in front of the seed rope guide tube, it can freely turn the soil and apply fertilizer without the presence of the seed rope, while the seed rope guide tube can place the seed rope on the path after cleaning and fertilization, with less mutual interference.

[0014] Furthermore, a drip irrigation shovel for laying drip irrigation tape is provided behind the seed rope guide tube. The drip irrigation shovel is connected to the rear connecting rod, and the drip irrigation shovel and the seed rope guide tube are staggered.

[0015] By integrating drip irrigation tape installation into the sowing process, fertilization, sowing, and irrigation can be completed in one go. Furthermore, the staggered arrangement of the drip irrigation shovel and seed rope guide pipe reduces the interference of the drip irrigation shovel on the seed rope installation process.

[0016] Furthermore, a compaction wheel for compacting the soil surface is provided at the rear of the drip irrigation shovel.

[0017] Through the aforementioned technical solutions, the application of rollers makes the entire process of sowing, fertilizing, and laying drip irrigation tape more compact and efficient. Multiple agricultural activities are completed in a single mechanized operation, improving overall work efficiency and reducing the number of times agricultural machinery needs to travel through the field.

[0018] Furthermore, the rear connecting rod is provided with a mounting seat, the bottom of which is hinged to the first connecting rod and the press wheel, and the top of the mounting seat is provided with a nut, on which a lead screw is mounted, and the lead screw is hinged to the first connecting rod.

[0019] The above technical solution allows for the adjustment of the height of the press wheel by rotating the lead screw, thereby changing its pressure on the soil.

[0020] Furthermore, the mounting base is equipped with a drive motor for driving the lead screw to rise and fall; or, the lead screw is equipped with a handle that facilitates rotating the lead screw.

[0021] The above technical solution enables the adjustment of the height of the press wheel.

[0022] Furthermore, the seed rope frame includes a support rod, a mounting plate, and a storage roller. The mounting plate is provided with at least two mounting portions, and the storage roller and the mounting portions are detachably connected.

[0023] The above technical solution allows multiple installation sections to be loaded with multiple storage rollers simultaneously, supporting multi-row sowing and improving operational efficiency. Attached Figure Description

[0034] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0035] like Figures 1 to 3 As shown, this utility model provides a four-bar linkage synchronous contour-following seed rope sowing mechanism, including a seed rope frame 10, a seed rope guide tube 20, an upper link 30, a lower link 31, a front link 32, and a rear link 33. The upper link 30 and the lower link 31 are parallel and their two ends are respectively hinged to the front link 32 and the rear link 33 to form a four-bar linkage mechanism. The seed rope guide tube 20 is connected to the rear link 33. A seed furrow opener 40 is installed on the seed rope guide tube 20. The seed furrow opener 40 is located in front of the seed rope guide tube 20, and the seed rope guide tube 20 guides the seed rope into the furrow.

[0036] The relatively fixed spacing of the seed rope sowing significantly improves sowing accuracy. Secondly, the four-bar linkage automatically adjusts the height of the furrow opener based on ground undulations and soil hardness, maintaining a relatively constant tillage depth and preventing issues like unstable or shallow tillage. This helps ensure seeds are planted at the set soil depth, improving sowing quality. Because the four-bar linkage adapts to terrain changes and maintains a stable working posture, it effectively reduces the impact of bumps during seed rope sowing on sowing accuracy, further improving sowing quality, reducing the need for manual intervention, increasing overall work efficiency, and lowering labor intensity. Furthermore, the short synchronous contour-following transmission stroke of the four-bar linkage improves its efficiency. The seed furrow opener 40 is directly mounted on the seed rope guide tube 20, eliminating the need for additional tubes. The seed rope guide tube 20 serves a dual purpose, with fewer parts and a more compact structure.

[0037] Furthermore, a force-reinforcing spring 34 is provided between the upper link 30 and the lower link 31, and the force-reinforcing spring 34 is inclined forward and backward. The presence of the force-reinforcing spring 34 provides additional elastic support, allowing the four-bar linkage to respond more flexibly to changes in the ground. When encountering undulating terrain, the force-reinforcing spring 34 can absorb some of the impact and help the system quickly return to the preset working posture, ensuring that the seed furrow opener 40 maintains the set tillage depth as much as possible. The inclined setting of the force-reinforcing spring 34 helps to enhance the stability of the seed rope sowing mechanism in the forward direction. When the seed rope sowing mechanism encounters obstacles or sudden changes in terrain, the force-reinforcing spring 34 not only provides cushioning in the vertical direction, but also resists lateral swaying through the horizontal component force provided by its inclined angle, thereby ensuring the stable operation of the seed rope guide tube 20 and the seed furrow opener 40 as much as possible.

[0038] It should be noted that both the upper connecting rod 30 and the lower connecting rod 31 have two sets, connected in pairs by the front connecting rod 32 and the rear connecting rod 33. Two sets of force-applying springs 34 can be provided, positioned on both sides of the four-bar linkage for greater stability. The bottom end of the seed rope guide tube 20 is bent away from the seed furrow opener 40, further distancing the seed rope from the seed furrow opener 40. The seed furrow opener 40 can be a small plow tip.

[0039] It should be noted that the force-adding spring 34 can tilt from front to back or from back to front along the seed rope sowing mechanism to resist lateral swaying.

[0040] Since different seeds require different sowing depths, a mounting seat 50 for installing the seed rope guide tube 20 is provided on the rear connecting rod 33 to accommodate different seed sowing needs. The mounting seat 50 has a mounting sleeve 51 and a fixing bolt 52. The seed rope guide tube 20 passes through the mounting sleeve 51 and can be raised and lowered vertically. The fixing bolt 52 passes through the mounting sleeve 51 to press the seed rope guide tube 20 firmly. The ability of the seed rope guide tube 20 to be raised and lowered vertically means that the sowing depth can be precisely adjusted according to actual needs, and the furrow depth can also be adjusted so that the seeds can be planted at the target depth.

[0041] To further improve sowing efficiency, the seed rope frame 10 includes a support rod 11, a mounting plate 12, and a storage roller 14. The seed rope is wound around the storage roller 14, and one end passes through the seed rope guide tube 20. The mounting plate 12 is provided with four mounting parts 13, and the storage roller 14 is provided with two. The storage roller 14 and the mounting parts 13 are detachably connected, supporting multi-row sowing and improving work efficiency.

[0042] Accordingly, there are two seed rope guide tubes 20, each equipped with a seed furrow opener 40. The two seed rope guide tubes 20 allow for the simultaneous processing of two seed ropes, which can significantly improve sowing speed and work efficiency.

[0043] Fertilization is usually required at the same time as sowing. In the prior art, the fertilizer furrow opener 60 is located behind the seed rope guide tube 20. During the movement, the fertilizer furrow opener 60 may accidentally come into contact with the seed rope, causing the seed rope to be cut or pulled. Therefore, in this utility model, the fertilizer furrow opener 60 is located in front of the seed rope guide tube 20 and is connected to the front connecting rod 32. The fertilizer furrow opener 60 can freely turn the soil and apply fertilizer when there is no seed rope. The seed rope guide tube 20 can place the seed rope on the path after cleaning and fertilization, with less mutual interference. The four-bar linkage mechanism can also make the furrow opening depth of the fertilizer furrow opener more consistent, which is suitable for different undulating ground and ensures the quality of fertilization.

[0044] It should be noted that the fertilizer trencher 60 can be a fertilizer shovel.

[0045] Furthermore, a drip irrigation shovel 70 for laying drip irrigation tape is provided behind the seed rope guide tube 20. The drip irrigation shovel 70 is connected to the rear connecting rod 33, and the drip irrigation shovel 70 and the seed rope guide tube 20 are staggered. Integrating the drip irrigation tape laying into the sowing process allows fertilization, sowing, and irrigation to be completed in one go. In addition, the staggered arrangement of the drip irrigation shovel 70 and the seed rope guide tube 20 reduces the interference of the drip irrigation shovel 70 on the seed rope laying process.

[0046] Furthermore, a compaction wheel 80 for pressing the soil surface is located at the rear of the drip irrigation shovel 70. The application of the compaction wheel 80 makes the entire process of sowing, fertilizing, and laying drip irrigation tape more compact and efficient. Multiple agricultural activities are completed in a single mechanized operation, improving overall work efficiency and reducing the number of times agricultural machinery needs to travel back and forth in the field.

[0047] Since different seeds require different soil compaction levels, the bottom of the mounting base 50 is hinged to the compaction wheel 80 via a first connecting rod 53, and the top of the mounting base 50 is equipped with a nut 54, which is fixedly connected to the mounting base 50. A lead screw 55 is mounted on the nut 54, and the lead screw 55 is hinged to the first connecting rod 53. By rotating the lead screw 55, the height of the compaction wheel 80 can be adjusted, thereby changing its pressure on the soil.

[0048] It should be noted that the hinge point between the lead screw 55 and the press wheel 80 is different from the hinge point between the first connecting rod 53 and the press wheel 80.

[0049] To facilitate the adjustment of the height of the press wheel 80, a handle 56 is provided on the lead screw 55 to facilitate the rotation of the lead screw 55. By rotating the handle 56, the lead screw 55 is raised or lowered relative to the nut 54, thereby driving the press wheel 80 to rise or fall.

[0050] Understandably, in other embodiments, the seed rope guide tube can also be a telescopic tube, which allows for height adjustment while maintaining a more compact structure.

[0051] Understandably, in other embodiments, the seed furrow opener may also be directly fixedly connected to the rear connecting rod.

[0052] Understandably, in other embodiments, the storage rollers can be set in numbers of three, four, five, etc., and the seed rope guide tubes can also be set in multiple numbers of numbers of three, four, five, etc., further improving sowing efficiency.

[0053] Understandably, in other embodiments, the mounting base is equipped with a drive motor that drives the lead screw to lift, thereby achieving electric lifting.

[0054] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
