Description

Technical Field

[0001] This utility model relates to the field of melon cultivation, and in particular to a field melon seedling planting device. Background Technology

[0002] In modern agricultural production, field planting has become a common method of muskmelon cultivation due to its widespread market demand and high economic value. Seedling planting is a crucial step in the field cultivation of muskmelons, directly affecting their later growth and final yield. The quality of the planting hole, including its depth, width, and soil looseness, are key factors influencing muskmelon seedling growth. Therefore, how to efficiently and accurately prepare planting holes has become an important issue for improving the efficiency and quality of muskmelon cultivation.

[0003] In the practical operation of melon cultivation, the creation of planting holes typically relies on specific tools and methods. Currently, the most commonly used tool for drilling planting holes by farmers is a manual metal punch. This tool mainly consists of a metal handle and a cylindrical metal clump at the bottom. When using it, farmers manually press the metal clump downwards to create the planting hole. This method is simple and easy to implement, requiring no complex operating skills, and is therefore widely used in agricultural production. However, this traditional drilling method also has some limitations, especially in terms of soil preparation.

[0004] Existing manual hole-drilling tools using metal boulders exert strong pressure on the soil walls and bottom of the planting hole during insertion, due to the solid structure of the metal boulders. This pressure causes soil particles to compact, forming a compacted layer. This compacted soil not only affects soil aeration and moisture retention but also hinders root growth in melon seedlings. Roots struggle to penetrate the compacted soil layer, preventing them from fully absorbing water and nutrients from deeper layers. Furthermore, soil compaction leads to slow seedling growth and weak physique, and in severe cases, can even affect melon yield and quality. These problems reduce agricultural efficiency and increase labor intensity and costs for farmers. Therefore, improving existing hole-drilling tools to reduce soil compaction and improve the survival rate and growth quality of melon seedlings has become an urgent problem to be solved in agricultural production. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] In one embodiment, such as Figure 1As shown, a field muskmelon seedling planting device is provided, which includes:

[0021] A hole-drilling assembly, comprising an outer cylinder 100 and a conical soil-breaking head 110, wherein the conical soil-breaking head 110 is disposed at the front end of the outer cylinder 100 and is used to break the soil to form a planting hole;

[0022] The soil loosening linkage component includes a soil loosening blade 120, which is disposed on the side wall of the conical soil breaking head 110. The soil loosening blade 120 cuts the surrounding soil when the outer cylinder 100 moves downward, forming a step of breaking the soil first and then loosening the soil.

[0023] A handle 130 is connected to the rear end of the outer cylinder 100 and is used to operate the outer cylinder 100 to move downward.

[0024] In this embodiment, the bottom surface of the conical soil-breaking head 110 is fixedly connected to the front end of the outer cylinder 100. When the operator holds the handle 130 to perform seedling planting, a vertical force is first applied downwards by gripping the handle 130. This force is transmitted to the conical soil-breaking head 110 at the front end via the outer cylinder 100. The conical soil-breaking head 110, with its sharp tip and conical curved surface design, generates significant pressure upon initial contact with the soil, quickly piercing the soil surface and advancing downwards to form a preliminary planting hole outline. As the outer cylinder 100 continues to move downwards, the conical soil-breaking head 110 continuously expands the diameter of the planting hole. Simultaneously, due to its conical structure, it primarily exerts an outward displacing effect rather than a compacting effect on the surrounding soil, creating favorable conditions for subsequent soil loosening operations. After the conical soil-breaking head 110 completes the initial soil breaking, the loosening blades 120 mounted on the sidewalls begin to contact the soil. As these blades move downwards, they actively cut the soil around the planting hole wall laterally, breaking down potentially compacted soil layers into several independent soil units, effectively disrupting the continuous compaction structure of the soil. The cut soil units retain certain gaps and air passages, significantly improving the soil porosity and permeability inside the planting hole, providing a favorable physical environment for the respiration and water infiltration of the melon seedling roots. Simultaneously, the cutting action of the loosening blades 120 also breaks the continuous state of soil capillaries, reducing the possibility of rapid water evaporation along the hole wall and improving the water retention capacity of the planting hole. Through this organic combination of the hole-drilling component and the loosening linkage component, this device maintains soil looseness while forming the planting hole, overcoming the defects of traditional manual hole-drilling devices with metal lumps that easily cause soil compaction and hardening, creating favorable conditions for the growth of melon seedling roots and effectively promoting the robust growth of seedlings.

[0025] like Figure 2As shown, in one embodiment, the number of soil loosening blades 120 is six, and the six soil loosening blades 120 are evenly arranged on the outer side wall of the conical soil breaking head 110 around the axis of the conical soil breaking head 110.

[0026] In this embodiment, six loosening blades 120 are arranged radially and evenly on the outer wall of the conical soil breaker 110, with a 60-degree angle interval, using the central axis of the conical soil breaker 110 as a reference. This forms a multi-layered cutting network in three-dimensional space. In another embodiment, the six loosening blades 120 are arranged radially and evenly at different heights on the outer wall of the conical soil breaker 110. When the operator drives the outer cylinder 100 downward, the conical soil breaker 110 first breaks through the soil, and then the six loosening blades 120 sequentially enter the working state, simultaneously cutting the surrounding soil at their respective spatial positions. First, the six-blade structure greatly increases the cutting area and cutting frequency during a single downward press. Compared with traditional single-blade or double-blade designs, it can more thoroughly break up the soil within the same stroke, avoiding the problem of local soil compaction caused by insufficient cutting. Secondly, the even circumferential distribution of the blades ensures a balanced cutting force applied to the soil in the circumferential direction, preventing eccentric torque and thus guaranteeing the vertical stability of the outer cylinder 100 during the pressing process. This prevents the planting hole from tilting or becoming irregular in shape due to uneven force. Furthermore, the staggered arrangement of the six blades along the axial height ensures that the soil loosening effect covers the entire depth range of the planting hole, effectively loosening the soil from the opening to the bottom. Especially for the bottom of the hole, an area most prone to compaction by traditional hole diggers, the lowest blade can specifically cut and loosen the soil, completely solving the problem of roots struggling to penetrate. In addition, when the operator pulls the device upwards after pressing down, the six blades can further smooth and cut the hole wall, reducing the residue of large soil clods and facilitating subsequent seedling placement and soil covering.

[0027] like Figure 2 As shown, in one embodiment, the cutting edge of the loosening blade 120 faces outward from the outer cylinder 100 to facilitate cutting the surrounding soil.

[0028] In this embodiment, a radial layout with the blades facing outwards from the outer cylinder 100 offers significant mechanical advantages: when the operator applies a downward force, the outer cylinder 100 drives the loosening blades 120 to move vertically downwards. The outward-facing blade design generates shear stress rather than compressive stress at the moment of contact between the blade and the soil. This stress state is more conducive to the destruction and separation of the soil structure. Specifically, during the downward pressing process, the outward-facing blades push and cut the soil outwards, forming a loosening space larger than the diameter of the conical soil-breaking head 110. This ensures that the planting hole has sufficient effective volume to accommodate the melon seedling roots and backfill soil, while avoiding clogging of the hole due to soil rebound when the blade retracts. Simultaneously, this outward-facing blade design effectively reduces the downward resistance of the blades because the contact angle between the blade and the soil is closer to the cutting angle than the pressing angle, allowing the operator to complete the planting operation with less effort and reducing the labor intensity of long-term work. More importantly, the outward-cutting method disrupts the original soil structure, creating multiple irregular soil cracks and pores. These changes in microstructure significantly improve soil aeration and water permeability, facilitating the rapid adaptation of melon seedling roots to the new environment and the initiation of growth after planting. When the operator lifts the device from the soil, the outward-facing blade design effectively prevents soil from adhering to the blade surface, avoiding reduced soil loosening and cleaning difficulties caused by soil accumulation. Furthermore, the outward-facing blade allows for controlled soil disturbance during cutting, preventing excessive damage to the structural stability of the surrounding soil and maintaining the supporting capacity of the soil around the planting hole, thus preventing the hole walls from collapsing.

[0029] like Figure 1 As shown, in one embodiment, the handle 130 includes a grip 131 and an anti-slip texture 132. The grip 131 is disposed at the rear end of the outer cylinder 100, and the anti-slip texture 132 is disposed on the surface of the grip 131.

[0030] In this embodiment, the ergonomic design of the handle 130 fully considers the actual operating environment in the field and ergonomic principles. The grip 131 adopts a cylindrical or slightly flattened elliptical cross-section design that conforms to the human hand gripping posture. Its outer diameter is optimized so that it is neither too thick, causing the operator to have difficulty gripping, nor too thin, causing a rough feeling, thus ensuring comfort during long-term continuous work. More importantly, the surface of the grip 131 is processed with dense anti-slip textures 132. These anti-slip textures 132 can adopt various texture forms such as mesh knurling, annular grooves, or dot matrix protrusions. Their depth and spacing are specially designed to significantly increase the coefficient of friction between the operator's hand skin and the surface of the grip 131 without damaging the operator's palm. When the operator is planting seedlings in the field, the soil may contain a certain amount of moisture, or the operator's hands may be sweaty. Traditional smooth handles 130 are prone to slipping, which not only affects work efficiency but may also cause the operator to lose balance or damage the device due to sudden slippage. The anti-slip texture 132 design in this embodiment effectively solves this problem, allowing the operator to apply downward force stably even in wet environments, ensuring effective force transmission. Furthermore, the anti-slip texture 132 design allows the operator to apply force with more flexible gestures, such as pressing down with the palm or gripping and pulling with the fingers. This operational flexibility is particularly important in complex terrain or during extended work periods.

[0031] like Figure 2 and Figure 3 As shown, in one embodiment, the front end of the outer cylinder 100 is provided with a guide device 140, which is used to guide the conical soil-breaking head 110 to move vertically downward to ensure the verticality of the planting hole.

[0032] In this embodiment, the introduction of the guiding device 140 solves the problem that traditional manual hole diggers are prone to tilting of planting holes due to uneven force application or uneven ground during operation. In actual operation, the operator applies downward force through the handle 130. Although the intention is to apply force vertically downward, due to the instability of manual operation, a certain horizontal component force is often generated. If this component force is not effectively restrained, it will cause the conical soil-breaking head 110 to deviate from its vertical trajectory, forming a tilted planting hole. A tilted planting hole will bring a series of problems: First, the seedlings are difficult to keep upright after being placed in the hole and are prone to lodging; second, the tilted hole causes uneven distribution of roots within the hole, and the roots on one side may have limited growth due to insufficient space; third, during subsequent irrigation, the tilted planting hole will also result in uneven water distribution, affecting the balanced growth of the melon seedlings. In this embodiment, the guide device 140 strictly restricts the movement trajectory of the outer cylinder 100 to the vertical direction through mechanical constraints. Even if the operator is unstable during the application of force, the guide device 140 can automatically correct itself through its structural characteristics to ensure that the cone-shaped soil-breaking head 110 always moves downward in the vertical direction.

[0033] like Figure 3 As shown, in one embodiment, the guiding device 140 includes a guide rod 141 and a guide sleeve 142. The guide rod 141 is disposed at the front end of the outer cylinder 100, and the guide sleeve 142 is sleeved on the outside of the guide rod 141.

[0034] In this embodiment, the guiding device 140 employs a precision mechanical structure in which a guide rod 141 and a guide sleeve 142 cooperate, and its working principle is similar to that of a linear bearing or a sliding guide rail. The guide rod 141 is made of high-strength steel, and its surface is precision machined to achieve high dimensional accuracy and surface finish, thereby reducing the frictional resistance between it and the guide sleeve 142. The guide sleeve 142 is made of wear-resistant material, and its inner diameter forms a precise fit clearance with the outer diameter of the guide rod 141. This clearance ensures that the guide rod 141 can slide smoothly while limiting its radial wobble range. In terms of specific structural design, a through hole is provided through the center of the conical soil-breaking head 110 along the axial direction. The diameter of this through hole is slightly larger than the diameter of the guide rod 141, providing a passage for the guide rod 141 to pass through. The front end of the guide rod 141 passes through the perforation and protrudes a certain length beyond the front end of the conical soil-breaking head 110. Its front end is machined into a sharp conical or wedge-shaped tip. This tip design ensures that when the device starts working, the tip of the guide rod 141 contacts the soil surface before the conical soil-breaking head 110, easily piercing the surface crust or crop residue, thus paving the way for the subsequent smooth entry of the conical soil-breaking head 110 into the soil, acting as a guiding vanguard. The guide sleeve 142 is fixedly installed inside the outer cylinder 100, typically through welding or threaded fastening to form a rigid connection with the inner wall of the outer cylinder 100, ensuring its stable position. The rear end of the guide rod 141 is inserted into the guide sleeve 142, and the two are detachably connected. This design brings multiple technical advantages: First, the detachable structure facilitates the maintenance of the device. When the guide rod 141 wears out due to long-term use, it can be easily replaced with a new one, extending the overall service life of the device. Second, the detachable design allows the length of the guide rod 141 to be adjusted according to the specific requirements of different crop varieties for the depth of the planting hole; simply replacing the guide rod 141 with one of different lengths achieves depth adaptation. Third, the guide rod 141 can be removed during transportation and storage, reducing the overall length of the device and making it easier to carry and store. During operation, when the operator applies downward force, the guide rod 141 makes a precise linear sliding motion within the guide sleeve 142. The guide sleeve 142 strictly constrains the radial displacement of the guide rod 141, thereby ensuring the vertical movement trajectory of the conical soil-breaking head 110. The precise cooperation between the guide rod 141 and the guide sleeve 142 not only further improves the guiding accuracy and ensures the vertical movement of the conical soil-breaking head 110, but also enhances the applicability and maintainability of the device through its detachable design. The guide device 140 ensures the verticality of the planting hole, which helps to improve the survival rate and growth quality of melon seedlings and provides a reliable technical guarantee for the precision and standardized seedling planting operations in modern agriculture.

[0035] In one embodiment, the rear end surface of the guide rod 141 is provided with a threaded groove, the inner wall of the guide sleeve 142 is provided with a threaded inner wall, and the guide rod 141 and the guide sleeve 142 are threadedly connected.

[0036] In this embodiment, the connection between the guide rod 141 and the guide sleeve 142 is designed as a threaded connection, which not only provides reliable axial connection strength, but more importantly, enables precise adjustment of the extension length of the guide rod 141. In actual agricultural production, different crop varieties have significantly different requirements for the depth of planting holes. For example, melons and watermelons usually require deeper planting holes to facilitate root development, while tomatoes, peppers, and other solanaceous crops may require relatively shallower planting holes. Traditional fixed guide rod 141 devices cannot meet these diverse needs, and farmers often need to purchase multiple hole diggers of different specifications, increasing production costs and equipment management difficulties. By simply rotating the guide rod 141, changing the number of turns of the thread into the guide sleeve 142, the length of the guide rod 141 extending beyond the conical soil-breaking head 110 can be precisely adjusted. The thread pitch is typically designed to be 1-2 mm, meaning that with each rotation, the extension length of the guide rod 141 changes precisely by one thread pitch. Not only is it simple and quick to operate, requiring no tools and can be completed by hand, but the adjusted position remains stable due to the self-locking property of the thread, preventing loosening during vibration or stress. Furthermore, the threaded connection provides a standardized interface, allowing the guide rod 141 to be easily replaced with different diameters or tip shapes to adapt to different soil textures (such as clay, sand, and loam). For example, in harder clay, a guide rod 141 with a slightly larger diameter and sharper tip can be selected to improve piercing ability; in loose sandy soil, a guide rod 141 with a smaller diameter and smoother surface can be selected to reduce frictional resistance. This improves the versatility and adaptability of the seedling planting device, enabling it to serve more types of crop cultivation, increasing the overall utilization rate and economic value of the equipment, and has significant practical implications for promoting standardized seedling planting technology and advancing agricultural mechanization.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
