Technical Field
[0001] This application relates to the field of agricultural implements technology, and more specifically, to a ditching and ridging device for yam cultivation. Background Technology
[0002] Yam, belonging to the genus Dioscorea in the family Dioscoreaceae. Dioscorea alata L., commonly known as large yam, vegetable yam, or foot-shaped yam in southern China, is an important food crop in Africa, Asia, and the Pacific. Dioscorea alata tubers are rich in nutrients, containing abundant carbohydrates, protein, plant polysaccharides, and vitamin C. The tubers can be stored for up to six months after harvest. This utility model applies specifically to the Dioscorea alata variety.
[0003] The common planting method for yams is ridge planting, which requires digging furrows and making ridges before planting.
[0004] Because the ridge size required for yam cultivation differs from the basic size of ditching and ridging machines developed for fruit and vegetable cultivation, manual adjustment of ridge height, width, and slope is necessary in actual production. Small and irregular plots exist in yam cultivation, limiting the use of large ridging machines and making ridging operations difficult, necessitating manual ridging. Therefore, there is an urgent need for a tool that can meet the requirements of trenching and ridging before planting yams. Utility Model Content
[0005] This application aims to address at least one of the technical problems existing in the prior art or related technologies.
[0006] Therefore, this application provides a ditching and ridging tool for yam planting, which can meet different operational needs in the yam planting process, reduce the number of tools required in the planting process, and improve planting efficiency.
[0007] This application provides a ditching and ridging device for yam cultivation, comprising a handle, a connecting rod, a first shovel head, and a second shovel head; wherein, the connecting rod is fixedly connected to the handle; the first shovel head is detachably disposed at the end of the connecting rod away from the handle, and the first shovel head is a rectangular shovel head, belonging to an acute-angle ditching device; the second shovel head is detachably disposed at the end of the connecting rod away from the handle, and the second shovel head is an arc-shaped shovel head, used for laying shallow ditches; the first shovel head and the second shovel head can be detached relative to the connecting rod.
[0008] In some embodiments, the first shovel head includes: a pyramidal shovel face; the rectangular shovel face of the first shovel head and the pyramidal shovel face form a folded surface.

[0021] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.
[0023] The following reference Figures 1 to 3 This application describes a yam planting trenching and ridging device provided according to some embodiments.
[0024] like Figure 1 , Figure 2 As shown, a yam planting trenching and ridging device provided according to some embodiments of this application includes a handle 1, a connecting rod 2, a first shovel head 3, and a second shovel head 4; wherein, the connecting rod 2 is fixedly connected to the handle 1; the first shovel head 3 is detachably disposed at the end of the connecting rod 2 away from the handle 1, the first shovel head 3 is a rectangular shovel head, and the first shovel head 3 is an acute-angled trenching device; the second shovel head 4 is detachably disposed at the end of the connecting rod 2 away from the handle 1, the second shovel head 4 is an arc-shaped shovel head, and the second shovel head 4 is a shovel head used for laying shallow trenches; the first shovel head 3 and the second shovel head 4 can be detached relative to the connecting rod 2.
[0025] In this embodiment, the upper end of the connecting rod 2 is fixed with a handle 1, and the lower end is fixed with a shovel head. Depending on the different stages and specific needs of yam planting, either a first shovel head 3 or a second shovel head 4 is selected. The first shovel head 3 is a rectangular shovel head, which is an acute-angled furrow opener. The first shovel head 3 can cut into the soil more easily, reducing resistance and facilitating the creation of a trapezoidal ridge that is wider at the bottom and narrower at the top, providing a good soil environment for yam planting. The second shovel head 4 is an arc-shaped shovel head. During the digging process, a groove that is deeper on the outside and shallower on the inside is directly formed, meeting the needs of shallow furrow planting technology for yams. By setting a detachable first shovel head 3 and a second shovel head 4, this furrow opener and ridge opener has multiple functions, meeting different operational needs in the yam planting process, reducing the number of tools required in the planting process, and improving planting efficiency.
[0026] In some possible embodiments, such as Figure 1 As shown, the first shovel head 3 includes: a pyramidal shovel surface 31; the rectangular shovel surface of the first shovel head 3 and the pyramidal shovel surface 31 form a folded surface.
[0027] In this embodiment, the first shovel head 3 is composed of an upper rectangular shovel surface and a lower hollow pyramidal shovel surface 31. The hollow pyramidal shape allows the shovel surface to generate greater pressure with a smaller contact area when it comes into contact with the soil, making it easier to cut into the soil and reducing resistance when ditching. Furthermore, the upper rectangular shovel surface and the lower hollow pyramidal shovel surface 31 form a folded surface, which facilitates the shaping of a trapezoidal ridge that is wider at the bottom and narrower at the top. The folded surface makes the first shovel head 3 cut into the soil more smoothly. When the shovel head comes into contact with the soil, the folded surface can guide the soil to flow in a specific direction, reducing the soil's resistance to the shovel head and allowing the shovel head to enter the soil more quickly and deeply, thus improving the speed and quality of ditching.
[0028] In some possible embodiments, such as Figure 1 As shown, the first shovel head 3 has a flat rectangular structure.
[0029] In this embodiment, during ditching, the flat rectangular shovel can easily catch the soil being shoveled. At the same time, when the ditching is completed, the back of the rectangular shovel is different from the shovel head of the traditional ridging device, which has a distinct inward fold. Instead, it has a flat rectangular structure, which can be used to further shape the ridges. The operator can use the flat surface of the shovel head to pat the sides of the ridges, making the ridges more solid and regular, which is beneficial to the growth of yams.
[0030] In some possible embodiments, such as Figure 1 As shown, the handle 1 and the connecting rod 2 are ergonomically designed. The handle 1 has an anti-slip texture, and the handle 1 and the connecting rod 2 are connected by threads.
[0031] In this embodiment, the handle 1 and the connecting rod 2 conform to the human hand's gripping habits and adapt to the natural shape of the human hand, reducing hand fatigue and discomfort during long-term operation. The surface of the handle 1 has an anti-slip texture, which increases the friction with the operator's hand, prevents slippage during operation, and increases the safety of use. At the same time, the handle 1 and the connecting rod 2 are connected by a threaded connection. The thread improves the tightness between the handle 1 and the connecting rod 2, and the thread makes it easy to disassemble and replace the handle 1 or the connecting rod 2 if it is damaged, thus improving the convenience of use.
[0032] In some possible embodiments, such as Figure 3 As shown, the connecting rod 2 has external threads, and the first shovel head 3 and the second shovel head 4 have internal threads, with the external threads and internal threads engaging.
[0033] In this embodiment, the external thread of the connecting rod 2 and the internal threads of the first shovel head 3 and the second shovel head 4 mesh with each other through rotation to achieve a tight fit and form a stable connection. In practical applications, operators can select the first shovel head 3 and the second shovel head 4 according to different stages and specific needs of yam planting. The threaded connection facilitates the replacement of the shovel heads, thereby enabling the trenching and ridging device to better adapt to the diverse needs of yam planting.
[0034] In some possible embodiments, such as Figure 2 As shown, the second shovel head 4 includes: a support crossbar 41; two support longitudinal bars 42, which are disposed at both ends of the support crossbar 41; two arc-shaped baffles 43, which are disposed at the bottom of each support longitudinal bar 42; and two triangular teeth 44, which are disposed on each arc-shaped baffle 43.
[0035] In this embodiment, when the operator uses the second shovel head 4, the two arc-shaped baffles 43 of the second shovel head 4 are set at the bottom of the supporting longitudinal rod 42 and are symmetrically distributed. The triangular teeth 44 of the second shovel head 4 are cut into the soil layer. The connecting rod 2 is pulled backward, which drives the supporting horizontal rod 41, the supporting longitudinal rod 42 and the arc-shaped baffles 43 to move backward together. During this process, the arc-shaped baffles 43 will carry away the soil and form the groove required for the shallow trench laying. At the same time, the lower part of the arc-shaped baffles 43 can compact the soil surface while digging, making the groove more stable. The connecting rod 2 is pulled backward continuously until the required shallow trench laying length is completed, so that the second shovel head 4 is pulled out to prepare for the next operation. Moreover, the two arc-shaped baffles 43 can form two shallow trenches in one operation, and the distance between the two shallow trenches is within the optimal plant spacing range for yam ridge planting, which can significantly improve the efficiency of shallow trench laying in yam planting and reduce the time and labor costs of repeated operations.
[0036] In some possible embodiments, such as Figure 2 As shown, each arc-shaped baffle 43 is arc-shaped, and each triangular tooth 44 is disposed at the end of an arc-shaped baffle 43.
[0037] In this embodiment, the synergistic effect of the arc-shaped baffle 43 and the triangular teeth 44 makes the shaping of the shallow trench more precise. The groove shape formed by the arc-shaped baffle 43 is regular and meets the needs of yam planting. Compared with the traditional trenching shovel head, this second shovel head 4 can significantly improve work efficiency. The arc-shaped baffle 43 can quickly remove soil and form a groove, while the triangular teeth 44 reduces the resistance when entering the soil, making the whole digging process smoother. In addition, the lower part of the arc-shaped baffle 43 compacts the soil surface while digging, enhancing the stability of the shallow trench.
[0038] In some possible embodiments, such as Figure 2 As shown, threaded holes are symmetrically distributed on both sides of the support crossbar 41, and two support longitudinal bars 42 are threadedly connected to the support crossbar 41.
[0039] In this embodiment, threaded holes are symmetrically distributed on both sides of the support crossbar 41. The symmetrical distribution can ensure the balance of the structure, so that the two support longitudinal bars 42 can be evenly stressed. Through the threaded connection, the support longitudinal bars 42 are firmly installed on the support crossbar 41 to form a stable structure. When the support longitudinal bars 42 need to be replaced or repaired, they can be easily disassembled, which improves the service life and economic benefits of the furrowing and ridging device.
[0040] In some possible embodiments, such as Figure 2 As shown, the support rod 42 and the connecting rod 2 are perpendicular to each other.
[0041] In this embodiment, during excavation, the vertical angle enables the support rod 42 to transmit the operator's thrust more efficiently. When the connecting rod 2 is subjected to forward thrust, the vertical angle ensures that the support rod 42 completely converts the force into the excavation action of the arc-shaped baffle 43, reducing energy loss in the structure and thus improving excavation efficiency.
[0042] In some possible embodiments, such as Figure 2 As shown, the width of the arc-shaped baffle 43 ranges from 8 to 10 cm.
[0043] In this embodiment, the width and spacing of the shallow planting trenches are crucial for yam growth. Too narrow a spacing between the trenches leads to competition for water and nutrients between plants, and overlapping leaves reduce the plant's light energy utilization rate, affecting tuber development. On the other hand, too wide a spacing between the trenches wastes soil resources and reduces yield per unit area. A trench width of 8-10 cm is suitable for the growth needs of the yam-based yam variety, providing sufficient growth space for yam tubers while avoiding the consumption of soil resources.
[0044] When this yam planting furrowing and ridging device is in operation, depending on the different stages and specific needs of yam planting, the operator rotates the first shovel head 3 or the second shovel head 4. The handle 1 and the connecting rod 2 are connected by threads to form a stable operating rod. The selected shovel head is then fixed to one end of the connecting rod 2 by engaging the internal thread with the external thread, ensuring a secure connection. When using the first shovel head 3, the operator holds the handle 1 and the connecting rod 2, and the pyramidal shovel face 31 of the first shovel head 3 cuts into the soil. The hollow pyramidal shovel face 31 generates greater pressure with a smaller contact area, easily cutting into the soil and reducing resistance. As the operator pushes the handle 1 forward, the folded surface of the first shovel head 3 guides the soil flow, shaping a trapezoidal ridge that is wider at the bottom and narrower at the top, or a rectangular ridge. The shovel head receives the soil that has been shoveled up, and after the furrow is opened, the flat surface of the shovel head is used to compact the side of the ridge, making the ridge more solid and regular. When using the second shovel head 4, the triangular teeth 44 of the second shovel head 4 are cut into the soil layer, and the connecting rod 2 is pulled backward, which drives the support crossbar 41, the support longitudinal bar 42 and the arc-shaped baffle 43 to move backward together. The arc-shaped baffle 43 carries away the soil and forms a groove that is deep on the outside and shallow on the inside, which meets the needs of shallow planting of yam. At the same time, the second shovel head 4 has two symmetrically distributed arc-shaped baffles 43, which can form two shallow grooves in one operation, significantly improving the laying efficiency. By setting the first shovel head 3 and the second shovel head 4, the furrow opener and ridge opener has multiple functions and can meet the different operational needs in the process of planting yam.
