Description

Technical Field

[0001] This utility model relates to the field of seeding equipment technology, and specifically to a folding row guide for seeding equipment. Background Technology

[0002] In modern agricultural production, mulching technology has significantly increased crop yields and farmers' income by promoting crop growth and suppressing weeds and pests, and is widely used in the agricultural sector. With the development of this technology, higher demands are placed on the performance of mulched seeders. As a key component of precision seeding, the row marker directly affects seeding accuracy and efficiency. At the same time, the modernization of modern agriculture is accelerating, and the market demand for efficient, precise, and portable seeding equipment continues to grow. Precision seeding has become an essential requirement for agricultural production, and the row marker plays a crucial role in this process. It helps the seeder quickly and accurately complete large-area seeding operations, standardizes row spacing, ensures uniform seeding, and facilitates subsequent field management (such as fertilization and weeding).

[0003] The development of row markers is closely linked to that of seeders. In cotton sowing, row marking is crucial, needing to meet the requirements of mechanized precision hill-planting technology, Xinjiang planting patterns, and agronomical practices, while preventing double-seeding and missed sowing. Its working principle is to mark furrows in the soil at specified intervals next to the machine during sowing, providing a reference point for the next stroke and ensuring accurate spacing between adjacent rows.

[0004] Traditional row paddles are mostly fixed, relying on simple mechanical structures (such as metal rods or discs) to draw straight lines on the ground and maintain consistent row spacing. However, with the rapid development of modern agriculture, traditional fixed row paddles can no longer meet diverse needs. Currently, row paddles can be classified according to their level of automation as manual, semi-automatic, and fully automatic; and according to their lifting mechanism as lever-operated, mechanical, and hydraulic. Manual lifting mechanisms are often used in small machinery due to operational limitations; the widely used hydraulic row paddles, which use hydraulic systems to control unfolding and folding, are easy to operate and suitable for large agricultural machinery.

[0005] However, existing rowing devices still have many shortcomings. On the one hand, their structures are generally simple, and although the manufacturing cost is low, their design has flaws. Most adopt a hinge-and-frame structure, using a marking disc at the end of the frame to row. During retrieval, manual pulling of the hinge moves the frame to lift the rowing arm off the ground, and the frame is pressed into the field solely by its own weight. Increasing the weight of the frame to ensure rowing depth actually increases the difficulty of using the device.

[0006] On the other hand, existing row markers have fixed specifications and the spacing between rows cannot be adjusted, making it difficult to flexibly adjust the spacing according to actual planting needs. Furthermore, fixed row markers occupy a large space during transportation and storage, and the spacing between row markers on both sides is difficult to match when operating in small fields, resulting in significant limitations in their use. These problems severely restrict the efficient application of row markers in modern agricultural production and urgently require innovation and improvement. Summary of the Invention

[0007] The purpose of this invention is to provide a row marker for mechanized sowing operations, which optimizes the structure of traditional row markers, enables row spacing adjustment, reduces operational difficulty, and improves adaptability.

[0008] To achieve the above objectives, this utility model proposes a folding row marker for seeding equipment, comprising a marking disc assembly, a folding swing arm assembly, a support arm assembly, and a mounting base assembly;

[0009] The marking disc assembly is connected to the folding swing arm assembly. The marking disc assembly is configured to install a roller, which is used to mark grooves on the soil in the field.

[0010] The folding swing arm assembly is connected to the mounting base assembly via the support arm assembly. The folding swing arm assembly includes an adjusting arm structure, a hinge mechanism, and a connecting arm connected in sequence. The connecting arm is connected to the support arm assembly via a rotating shaft. The scribing disc assembly is installed at the adjusting end of the adjusting arm structure.

[0011] The mounting base assembly includes a power component and a support for connecting the seeding equipment. The power component is mounted on the support, and the telescopic end of the power component is connected to the support arm assembly.

[0012] The power unit is configured to drive the support arm assembly to rotate the connecting arm around the pivot, causing the folding swing arm assembly to unfold to the side of the seeding device, or to retract and fold the folding swing arm assembly to the inside of the seeding device.

[0013] Preferably, a slide bar is provided between the folding swing arm assembly and the support arm assembly, with one end of the slide bar connected to the support arm assembly and the other end of the slide bar connected to the hinge mechanism.

[0014] Preferably, a limit plate is provided between the outrigger assembly and the mounting assembly. The limit plate is configured to limit the rotation angle of the connecting arm driven by the outrigger assembly around the pivot.

[0015] Preferably, the scribing disc assembly also includes a connecting rod and an adjusting seat. The disc is connected to the adjusting seat via the connecting rod, and the adjusting seat is installed at the adjusting end of the adjusting arm structure.

[0016] Preferably, the adjusting arm structure includes a first square tube and a second square tube. The first square tube is embedded in the second square tube to form a telescopic sleeve structure. The second square tube is connected to a hinge mechanism. The first square tube is connected to a scribing disc assembly. The first square tube and the second square tube are locked together by a locking structure.

[0017] Preferably, the outrigger assembly includes a frame, a support base, and a rotating base. The frame is mounted on the support base, the rotating base is mounted on the top of the frame, the connecting arm is connected to the rotating base via a rotating shaft, the support base is mounted on the side wall of the frame, and the support base is provided with a support end for supporting the connecting arm.

[0018] Preferably, the power component is a hydraulic cylinder.

[0019] This utility model provides a foldable rowing device for sowing equipment, which, compared with the prior art, has the following substantial features and advancements: The foldable rowing device utilizes a power component to drive the support arm assembly, allowing the folding arm assembly to easily unfold to the side of the sowing equipment for rowing operations, or to retract and fold inwards. In scenarios such as moving plots, turning, or reversing at the edge of the field, the rowing device can be quickly folded, preventing it from interfering with equipment operation during non-operational periods. This greatly improves the continuity and overall efficiency of sowing operations, reduces auxiliary operation time, and the foldable design allows the rowing device to retract into the sowing equipment when not in use, effectively reducing the overall space occupied by the equipment. When the seeding equipment is being transported or parked in a space-constrained area, the risk of collision or damage caused by the protruding part of the row marker is avoided. At the same time, the mounting base assembly can be tightly connected to the seeding equipment, and the components work together to improve the overall integration of the seeding equipment. This makes the equipment more compact and flexible in field operations, adapting to different terrains and working environments. The adjusting arm structure in the folding swing arm assembly can adjust the position of the marking disc assembly. Through the adjusting arm structure, the marking depth and spacing can be flexibly adjusted according to different crop varieties, row spacing requirements, and soil conditions to meet diverse seeding operation needs, broaden the application range of the seeding equipment, and improve the equipment's versatility and practicality.

[0031] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] This invention proposes a foldable row divider for sowing equipment, aiming to optimize the structure of traditional row dividers, realize the row spacing adjustment function, reduce the difficulty of operation, and improve adaptability.

[0033] This invention discloses a foldable row marker drive arm assembly for a sowing device. This assembly allows the foldable swing arm to easily unfold to the side of the sowing device for row marking, or retract and fold inwards. The foldable design allows the row marker to retract into the sowing device when not in use, effectively reducing the overall space occupied by the device. This also avoids the risk of collision or damage to the protruding part of the row marker when transporting the sowing device or parking in confined spaces. Simultaneously, the adjustable arm structure in the foldable swing arm assembly allows for adjustment of the position of the marking disc assembly. This adjustment allows for flexible adjustment of the marking depth and spacing according to different crop varieties, row spacing requirements, and soil conditions, meeting diverse sowing needs, broadening the applicability of the sowing device, and improving its versatility and practicality.

[0034] like Figure 1 As shown, a folding row marker for a seeding device includes a marking disc assembly 1, a folding swing arm assembly 2, a support arm assembly 3, and a mounting base assembly 4.

[0035] The marking disc assembly 1 is connected to the folding swing arm assembly 2. The marking disc assembly 1 is configured to mount a roller 107, which is used to mark grooves on the soil in the field.

[0036] like Figure 1 As shown, the folding swing arm assembly 2 is connected to the mounting base assembly 4 via the support arm assembly 3. Figure 5 As shown, the folding swing arm assembly 2 includes an adjusting arm structure, a hinge mechanism 203, and a connecting arm 206 connected in sequence. The connecting arm 206 is connected to the support arm assembly 3 via a pivot. Figure 3 As shown, the scribing disk assembly 1 is installed at the adjusting end of the adjusting arm structure.

[0037] like Figure 7 Combination Figure 8 As shown, the mounting bracket assembly 4 includes a power unit and a support 401 for connecting the seeding equipment. The power unit is mounted on the support 401. The telescopic end of the power unit is connected to the support arm assembly 3.

[0038] Among them, such as Figure 1 Combination Figure 2 As shown, the power unit is configured to drive the outrigger assembly 3 to rotate the connecting arm 206 around the pivot, causing the folding swing arm assembly 2 to unfold to the side of the seeding device, or to retract and fold the folding swing arm assembly 2 inward toward the seeding device. For example, the power unit is a hydraulic cylinder 402.

[0039] According to some preferred embodiments of the present invention, such as Figure 1As shown, a slide bar 5 is provided between the folding swing arm assembly 2 and the support arm assembly 3. One end of the slide bar 5 is connected to the support arm assembly 3, and the other end is connected to the hinge mechanism 203. The slide bar 5 serves to guide the movement of the folding swing arm assembly 2. When the power unit drives the support arm assembly 3 to unfold or fold the folding swing arm assembly 2, the slide bar 5 guides the hinge mechanism 203 to move smoothly along a specific trajectory. Compared to the case without the slide bar 5, the movement of the folding swing arm assembly 2 is more linear and controllable, reducing the jamming or shaking caused by movement deviation. As a result, the rowing device switches operating states more smoothly, reduces the difficulty of operation for operators, improves the response speed of the equipment, and helps to improve the overall efficiency of the sowing operation.

[0040] Furthermore, the sliding rod 5 also provides additional support, further reinforcing the connection between the folding swing arm assembly 2 and the support arm assembly 3. During the marking operation, the reaction force generated by the soil on the marking disc assembly 1 is transmitted to the support arm assembly 3 through the folding swing arm assembly 2. The sliding rod 5 can share some of the force, preventing the hinge mechanism 203 from bearing excessive stress, thereby reducing the risk of component damage due to uneven force distribution.

[0041] like Figure 1 As shown, a limit plate 6 is provided between the support arm assembly 3 and the mounting assembly. The limit plate 6 is configured to limit the rotation angle of the connecting arm 206 driven by the support arm assembly 3 around the pivot.

[0042] The limiting plate 6 clearly defines the angle range of rotation of the connecting arm 206 driven by the support arm assembly 3 around the pivot, effectively preventing the folding swing arm assembly 2 from being over-extended or over-folded. During the operation of the seeding equipment, if the folding swing arm assembly 2 is over-extended, it may collide with surrounding obstacles, causing equipment damage or even endangering the safety of the operators; if it is over-folded, it may cause crushing damage to the power components and connecting lines inside the equipment.

[0043] like Figure 3 Combination Figure 4 As shown, the scribing disc assembly 1 also includes a connecting rod 101 and an adjusting seat 102. The roller 107 is connected to the adjusting seat 102 via the connecting rod 101. The adjusting seat 102 is mounted on the adjusting end of the adjusting arm structure.

[0044] By incorporating the connecting rod 101 and the adjusting seat 102, the connection between the roller 107 and the adjusting end of the adjusting arm structure becomes more adjustable. Operators can easily adjust the position of the roller 107 according to actual sowing needs. For example, when dealing with different soil types, if the soil is hard, the roller 107 can be appropriately lowered via the adjusting seat 102 to increase the pressure of the roller 107 on the soil, ensuring clear and appropriately deep furrows are created; if the soil is soft, the roller 107 can be appropriately raised to prevent excessively deep rows from affecting the sowing effect. This adjustable function allows the rower to adapt to various complex and changing soil conditions, greatly improving the adaptability and accuracy of sowing operations.

[0045] like Figure 5 As shown, the adjusting arm structure includes a first square tube 201 and a second square tube 202. The first square tube 201 is embedded in the second square tube 202 to form a telescopic sleeve structure. The second square tube 202 is connected to the hinge mechanism 203. The first square tube 201 is connected to the scribing disc assembly 1. The first square tube 201 and the second square tube 202 are locked together by a locking structure.

[0046] The adjusting arm structure employs a telescopic sleeve-like structure formed by embedding a first square tube 201 into a second square tube 202, providing operators with an extremely convenient method for length adjustment. Before actual sowing operations, workers can quickly and accurately change the overall length of the adjusting arm according to sowing row spacing requirements and different terrain conditions. Compared to some fixed-length or complex-method row marker adjusting arms, this telescopic sleeve-like structure requires only simple operation to complete length adjustment, greatly saving preparation time before sowing and improving operational efficiency. For example, when adjacent fields have different row spacing requirements, the adjusting arm can be quickly extended or retracted to meet new sowing needs.

[0047] like Figure 5 Combination Figure 6 As shown, the second square tube 202 and the hinge mechanism 203 are connected by screw 3 207 and nut 3 208. The two fixed ends of the hinge mechanism 203 are respectively installed on the upper and lower walls of the connecting arm 206 by spring pin 2 205, so that the second square tube 202 and the connecting arm 206 are connected.

[0048] like Figure 7 Combination Figure 8 As shown, the mounting bracket assembly 4 includes a support 401, a hydraulic cylinder 402, a self-locking nut 403, a second pin 404, and a third spring pin 405. The hydraulic cylinder 402 is located at the upper end of the support 401 and is connected to the support 401 by the self-locking nut 403. The support 401 is fixed to the folding swing arm assembly 2 by the second pin 404. The mounting bracket assembly 4 is fixed to the main beam of the seeder frame assembly.

[0049] like Figure 9 Combination Figure 10As shown, the support arm assembly 3 includes a frame 301, a support base 302, and a rotating base 303. The frame 301 is mounted on the support base 401. The rotating base 303 is mounted on the top of the frame 301. The connecting arm 206 is connected to the rotating base 303 via a pivot. The support base 302 is mounted on the side wall of the frame 301. The support base 302 is provided with a support end for supporting the connecting arm 206. The coordinated work between the components of the support arm assembly 3 improves the overall performance of the rowing device and the seeding equipment. The stable support arm structure ensures the smoothness of the folding swing arm assembly 2 during unfolding and folding, enabling the rowing device to quickly and accurately switch operating states. For example, the rotating base 303 is mounted on the top of the frame 301 via a spring pin 304.

[0050] The support arm assembly 3 provides excellent support and guidance for the connecting arm 206 and the entire folding swing arm assembly 2, enabling the marking disc assembly 1 to more accurately mark grooves on the ground, improving the accuracy and consistency of the sowing rows, which is conducive to improving sowing quality, promoting uniform growth of crops, and ultimately increasing crop yield and quality.

[0051] In this embodiment of the invention, a folding rowing device for a seeding equipment is used by the operator. The support 401 is installed and fixed onto the main beam of the seeder frame 301 assembly. Then, the hydraulic cylinder 402 is fixed to the support 401 using a self-locking nut 403. Next, the second pin 404 is inserted into the through hole on the support arm assembly 3 and fixed to the support 401. Then, the support arm assembly 3 is fixed to the rotating seat 303 using a first pin 305. Finally, the sliding rod 5 is fixed to the support seat 302 using a pin. Then, as... Figure 5 As shown, the connecting arm 206 and the second square tube 202 are connected by the hinge mechanism 203, and the position of the first square tube 201 in the second square tube 202 is adjusted. After adjustment, it is fixed by locking screw 204. Then, U bolt 108 is inserted into the slot on the adjusting seat 102 in the scribing disc assembly 1 to install and fix the first square tube 201. Then, U bolt 109 is used to fix the connecting sleeve 106 on the adjusting seat 102. Then, spring pin 105 is used to fix the connecting rod 101 to the connecting sleeve 106. Finally, screw 103 and nut 104 are used to fix the connecting rod 101 and the roller 107, thus completing the installation process of the entire device.

[0052] Hydraulic cylinder 402, through the action of a set of hydraulic pressures from the tractor, can extend and retract. When hydraulic cylinder 402 extends, the piston rod of hydraulic cylinder 402 pushes the support arm assembly 3 to rotate clockwise around pin 404. At the same time, the limit plate 6 drives the rotating seat 303 to rotate, and the connecting arm 206 rotates accordingly. The slide rod 5 drives the hinge mechanism 203 to rotate the second square tube 202 counterclockwise. The connecting arm 206 and the second square tube 202 are in the same straight line and rotate with the support arm assembly 3 until the roller 107 enters the soil and stops rotating.

[0053] As the unit moves forward, the roller 107 will draw a mark on the soil surface that can be recognized by the driver, marking the rows for subsequent sowing. After marking, the operator controls the tractor's hydraulic reverse output, the hydraulic cylinder 402 retracts, driving the support arm assembly 3 to rotate counterclockwise around the second pin 404. The limit plate 6 drives the rotating seat 303 to rotate, and the connecting arm 206 rotates to contact the support seat 302. Under the gravity of the second square tube 202, the connecting arm 206 and the marking disc assembly 1, the slide rod 5 slides along the inner groove of the support seat 302 until the marking disc assembly 1 returns to a horizontal state. The whole operation process is simple and convenient, and the inertial force during recovery is small, the positioning accuracy is high, and the length of the marking arm can be adjusted to meet the different agronomic requirements of current sowing operations.

[0054] This utility model is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, this utility model may have other implementation methods. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
