Description

Technical Field

[0001] This utility model relates to the field of ridging device technology, specifically a broad bean planting ridging device with adjustable spacing. Background Technology

[0002] In modern agricultural production, broad beans, as an important dual-purpose crop (grain and vegetable), play a crucial role in improving agricultural economic efficiency and ensuring food security through their cultivation and management. Ridging is a key step in broad bean cultivation; by constructing a planting pattern of alternating ridges and furrows, soil aeration can be effectively improved, field drainage optimized, soil temperature increased, and root development promoted. Ridging machines, as specialized agricultural machinery for efficient broad bean ridge preparation, significantly improve ridge formation efficiency and quality, providing strong support for the standardization and modernization of broad bean cultivation.

[0003] Utility model patent application number CN202320359514.0 discloses a rotary tiller and ridging integrated machine. The rotary tiller and ridging integrated machine includes a machine body connected to a tractor; a rotary tilling mechanism disposed on the machine body and used for tilling the soil; and a ridging mechanism disposed on the machine body, located behind the rotary tilling mechanism in the forward direction of the machine body, and used for ridging the tilled soil. By simultaneously setting the ridging mechanism and the rotary tilling mechanism on one machine body, the tilling and ridging of the land can be completed in one operation, thus improving efficiency.

[0004] Although this rotary tiller and ridging machine improves the efficiency of land tillage and ridging, the following problems still exist in actual use: In the machine's structural design, the ridging components and ridging shaft are fixedly connected. While this mechanical connection ensures operational stability, it has inherent limitations in flexibility. Due to this rigid connection, the center-to-center distance between adjacent ridging components cannot be dynamically adjusted. Furthermore, in actual agricultural production scenarios, due to differences in crop varieties, cultivation methods, and regional agronomy, the requirements for ridge width parameters (such as ridge width and ridge spacing) vary significantly. This lack of adjustability makes it difficult for the equipment to adapt to diverse ridging needs, limiting its application range and operational versatility to some extent. Therefore, we propose a ridging device for broad bean planting with adjustable spacing. Utility Model Content

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 protection scope of the present utility model.

[0037] This embodiment provides a technical solution:

[0038] Please see Figures 1-2 As shown, the adjustable spacing broad bean planting ridging device includes two side plates 10, which are symmetrically arranged; a drive shaft 12 is rotatably installed between the two side plates 10 at the upper rear side, and a first motor 13 for driving the drive shaft 12 to rotate is installed on the outer wall of the right side plate 10.

[0039] With the above configuration, the side plate 10, together with the mounting bracket 1, provides stable support for the whole.

[0040] In this embodiment, a mounting bracket 1 is bolted to the upper part between the two side plates 10. The mounting bracket 1 has an L-shaped cross-section. This shape design provides additional installation space and structural strength.

[0041] In this embodiment, two fixing brackets 11 are tightly welded to the rear end face of the mounting bracket 1, and the fixing brackets 11 are provided with connection holes. The fixing brackets 11 and the connection holes facilitate quick connection with power equipment such as tractors, enhance the adaptability of the device to external equipment, and ensure the stability and reliability of the overall structure during operation.

[0042] Please seeFigures 1-5 As shown, the ridging assembly 2 is used for ridging the plot and is installed on the lower front side between two side plates 10; it includes a rotating shaft 20 rotatably installed between the two side plates 10, with a limiting groove 200 on the outer wall of the rotating shaft 20; two symmetrical ridging cones 21 are provided on the left and right sides of the rotating shaft 20, the rotating shaft 20 passes through the ridging cones 21 and is slidably connected to the ridging cones 21, and a guide rail 211 is fixed to the inner wall of the opening of the ridging cone 21 and is slidably connected to the limiting groove 200; two opposite end faces of two adjacent ridging cones 21 are coaxially fixed with connecting sleeves 210, and support plates 22 are rotatably installed at the connecting sleeves 210; a T-shaped slider 23 is fixed to the top of the support plate 22, and a threaded hole 230 is provided at the front end of the slider 23; a transmission assembly 24 is provided between the rotating shaft 20 and the transmission shaft 12;

[0043] With the above settings, the ridging cone 21 is slidably connected to the rotating shaft 20, and the slider 23 is slidably connected to the groove 330, which facilitates the adjustment of the distance between the two ridging cones 21, thereby facilitating the adjustment of the ridge width.

[0044] Please see Figure 5 As shown, in this embodiment, a shaft hole 220 is formed at the bottom end of the support plate 22, and the connecting sleeve 210 passes through the shaft hole 220 and is rotatably connected to it. The shaft hole 220 at the bottom end of the support plate 22 and the connecting sleeve 210 are rotatably engaged, allowing the ridging cone 21 to flexibly change its angle and position during adjustment. This rotatable connection design ensures the structural integrity of the ridging assembly 2 while reducing adjustment resistance, making the adjustment of ridge width and ridge spacing smoother, reducing mechanical wear, and extending the service life of the equipment.

[0045] Please see Figure 4 As shown, in this embodiment, the transmission assembly 24 includes two symmetrical sprockets 240, with a chain 241 meshing between them. The sprocket 240 located on the front side is coaxially keyed to the drive shaft 12, and the sprocket 240 located on the rear side is coaxially keyed to the drive shaft 12. This transmission method can efficiently transmit the power of the drive shaft 12 driven by the first motor 13 to the rotating shaft 20. This structure has a stable transmission ratio and high transmission efficiency, which can ensure that the ridging cone 21 rotates at a uniform speed, ensuring the continuity and uniformity of ridging operations, and improving ridging quality and work efficiency.

[0046] In this embodiment, the support plate 22 and the slider 23 are integrally formed structures, and both the support plate 22 and the slider 23 are made of stainless steel. The integrated design increases the reliability and stability of the connection between the support plate 22 and the slider 23, and improves the stability during adjustment; the stainless steel material is suitable for complex field environments, prevents rust, and ensures that the slider 23 and the sliding groove 330 of the connecting frame 33 maintain good sliding fit accuracy over a long period of time.

[0047] Please seeFigure 1 and Figure 6 As shown, the adjusting component 3, used to adjust the spacing of the raised beds, is installed above the rotating shaft 20; it includes a double-ended lead screw 30 with bidirectional threads, and a second motor 32 for driving the double-ended lead screw 30 to rotate is installed on the outer wall of the right side plate 10; both ends of the double-ended lead screw 30 are threadedly connected to connecting blocks 31, and a connecting frame 33 is fixed to the bottom of the connecting block 31. The bottom of the connecting frame 33 is provided with a T-shaped slide groove 330, and the slider 23 is slidably connected to the slide groove 330; the front end face of the connecting frame 33 is provided with multiple adjusting holes 331, and a fixing bolt 34 is inserted through one of the adjusting holes 331. The rear end of the fixing bolt 34 is threadedly connected to the threaded hole 230.

[0048] With the above settings, and in conjunction with the connecting block 31 and connecting frame 33 driven by the double-headed screw 30, the ridge width and ridge spacing can be flexibly adjusted to meet diverse planting needs and improve the equipment's versatility and operational adaptability.

[0049] In this embodiment, multiple adjustment holes 331 are linearly and equally spaced in the horizontal direction. By inserting fixing bolts 34 into different adjustment holes 331 and connecting them with threaded holes 230, the positions of slider 23 and support plate 22 can be adjusted, thereby facilitating the adjustment of the distance between two adjacent ridge cones 21.

[0050] In this embodiment, the end bearing of the double-ended lead screw 30 is rotatably connected to the side plate 10, and the spiral directions of the threaded grooves at both ends of the double-ended lead screw 30 are opposite. This design allows the connecting blocks 31 on both sides to move in opposite directions synchronously under the drive of the second motor 32. This structure enables symmetrical adjustment of the ridging assembly 2, ensuring the accuracy of ridge width and ridge spacing adjustment, simplifying the adjustment operation process, and improving the ease of use of the equipment.

[0051] In this embodiment, the connecting block 31 and the connecting frame 33 are fixedly connected by bolts, and both the connecting block 31 and the connecting frame 33 are made of stainless steel. The bolt connection method has the advantage of reliable installation, while the stainless steel material ensures that the connection part will not deform or break in harsh environments such as moisture and mud, thus maintaining the stable operation of the adjustment component 3.

[0052] It is worth noting that the first motor 13 and the second motor 32 involved in this embodiment are existing conventional technologies, and will not be described in detail here.

[0053] When adjusting the ridge spacing: First, the user starts the second motor 32. The second motor 32 begins to work, and its output shaft drives the double-ended lead screw 30 with bidirectional threads to rotate. Since the spiral directions of the threaded grooves at both ends of the double-ended lead screw 30 are opposite, the rotation causes the connecting blocks 31 connected by threads at both ends to move synchronously in opposite directions. Subsequently, the connecting blocks 31 drive the connecting frame 33 at the bottom to move, and the connecting frame 33 then drives the two support plates 22 at the bottom and the ridging cones 21 at the bottom of the support plates 22 to move synchronously horizontally. When the ridging cones 21 on both sides move to a suitable distance, the ridge spacing adjustment is completed.

[0054] When adjusting the ridge width: First, the user loosens the fixing bolts 34 at the adjustment holes 331 on the front end of the connecting frame 33 to release the fixing constraint on the slider 23. Then, the user manually pushes the support plate 22, causing the slider 23 to slide within the T-shaped groove 330 at the bottom of the connecting frame 33, changing the position of the individual ridging cone 21 on the rotating shaft 20, thereby adjusting the opening width formed by the combination of ridging cones 21. Finally, according to the required ridge width, the fixing bolts 34 are inserted into the corresponding adjustment holes 331 and threadedly connected to the threaded holes 230 at the front end of the slider 23. After tightening, the position of the ridging cone 21 is fixed, completing the ridge width adjustment.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
