Technical Field
[0001] This utility model relates to the field of agricultural planting technology, specifically a seed planting hole-drilling machine. Background Technology
[0002] A seed planting hole-drilling machine is an agricultural machine mainly used to create holes or cavities for seeds before sowing to optimize the germination and growth environment. Its core functions include improving sowing efficiency, ensuring sowing accuracy, and reducing manual labor intensity. Seed planting hole-drilling machines improve the standardization and sustainability of sowing through mechanization and are an important part of modern agricultural technology.
[0003] After prolonged use, seed planting hole-drilling machines may experience unstable rotation of the drilling structure, leading to inconsistent drilling depth, hole misalignment, and even shaking and abnormal noises from the drilling components. This not only affects the sowing quality and equipment lifespan but also increases the workload of subsequent manual adjustments and replanting, reducing overall sowing efficiency. Unstable drilling may disrupt the seed implantation environment, hindering uniform germination and growth. Rotational instability may also exacerbate wear between parts, increasing equipment maintenance costs and failure rates, making it difficult to meet the high precision, high efficiency, and high stability requirements of modern agriculture for sowing operations. Utility Model Content
[0004] The purpose of this invention is to provide a seed planting hole-drilling machine to solve the problems mentioned in the background art, such as inconsistent drilling depth, hole position displacement, and even shaking and abnormal noise of the drilling components, which may be caused by the unstable rotation of the drilling structure.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a seed planting hole-drilling machine, comprising a support frame, a placement platform fixedly installed on the top of the support frame, a hole-drilling component arranged between the support frames, and an adjustment component provided at the outer end of the hole-drilling component;
[0006] Preferably, the drilling assembly includes movable seats, two of which are symmetrically fixedly installed on the inner wall of the support frame, and a rotating shaft is rotatably connected between the two movable seats. Multiple adjusting cylinders are movably connected to the outer end of the rotating shaft, a connecting plate is fixedly installed on the outer end of the adjusting cylinder, a protective cover is fixedly installed on the outer end of the connecting plate, and a drilling head is detachably connected to the outer end of the protective cover.
[0007] Preferably, the adjusting assembly includes threaded tubes, each of which is fixedly installed on one side of the adjusting cylinder, and each adjusting cylinder has a fixing bolt threadedly connected inside.
[0008] Preferably, the outer end of the rotating shaft is provided with six sets of drilling heads, and the rotating shaft is located directly below the placement platform.
[0009] Preferably, a push handle is fixedly installed on one side of the placement platform, and a movable wheel is detachably connected to the bottom of the support frame.
[0010] Preferably, the movable seat and the inner wall of the support frame are welded together, and the perforation heads are circumferentially distributed on the surface of the protective cover.
[0011] Preferably, the threaded tube and the fixing bolt are threadedly connected, and the fixing bolt extends to the inner wall of the adjusting cylinder and is threadedly connected to the rotating shaft.
[0012] Preferably, the nut of the fixing bolt is located at the outer end of the adjusting cylinder.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By setting up a drilling assembly, it is possible to achieve simultaneous drilling operations at multiple locations in the seed planting area. Two movable seats stably support the rotating shaft on the inner wall of the support frame. Multiple adjusting cylinders connected to the outer end of the rotating shaft can drive the drilling head to adjust its position. The cooperation between the connecting plate and the protective cover not only protects the drilling head but also ensures the stability of the drilling process, improves the accuracy of the drilling operation, and prevents the drilling head from shaking or deviating when rotating at high speed.
[0015] 2. By setting up the adjustment component and the threaded connection structure between the threaded tube and the fixing bolt, after the position of the adjustment cylinder is adjusted, the fixing bolt can be tightened to make it tightly connected to the rotating shaft, thereby firmly fixing the adjustment cylinder on the rotating shaft. This ensures that the drilling head will not shift position during operation, improves the stability and accuracy of drilling operations, and further meets the precise control requirements for drilling position in different planting scenarios.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides a technical solution: a seed planting hole-drilling machine, including a support frame 1, a placement platform 2 fixedly installed on the top of the support frame 1, a hole-drilling assembly arranged between the support frames 1, and an adjustment assembly provided at the outer end of the hole-drilling assembly. The hole-drilling assembly includes movable seats 51, two movable seats 51 symmetrically fixedly installed on the inner wall of the support frame 1, and a rotating shaft 52 rotatably connected between the two movable seats 51. The two movable seats 51 symmetrically fixed on the inner wall of the support frame 1 provide stable rotational support for the rotating shaft 52, so that the rotating shaft 52 can smoothly drive multiple adjusting cylinders 53 movably connected to its outer end to perform circular motion. Multiple adjusting cylinders 53 are movably connected to the outer end of the rotating shaft 52, and a connecting plate 54 is fixedly installed at the outer end of the adjusting cylinders 53. A protective cover 55 is fixedly installed at the outer end of the connecting plate 54, and a hole-drilling assembly is detachably connected to the outer end of the protective cover 55. The outer end of the rotating shaft 52 is equipped with six sets of drilling heads 56. The six sets of drilling heads 56 can perform multiple continuous drilling operations on the seed planting area on the placement platform 2 during one rotation of the rotating shaft 52, effectively improving drilling efficiency. The rotating shaft 52 is located directly below the placement platform 2. The movable seat 51 and the inner wall of the support frame 1 are welded together. The drilling heads 56 are circumferentially distributed on the surface of the protective cover 55. The drilling heads 56 and the protective cover 55 are detachably connected by a threaded structure. When the drilling heads 56 are worn or need to be replaced with drilling heads 56 of different diameters or shapes according to the planting requirements of different seeds, the operator can quickly complete the disassembly and installation by simply rotating the drilling heads 56, which greatly reduces the difficulty and time cost of replacement and maintenance. The tip of the drilling head 56 is treated with a quenching process, which significantly enhances its hardness and wear resistance and extends its service life.
[0024] A push handle 3 is fixedly installed on one side of the placement platform 2. A movable wheel 4 is detachably connected to the bottom of the support frame 1. The adjustment assembly includes threaded tubes 61, each threaded tube 61 fixedly installed on one side of the adjustment cylinder 53. Each adjustment cylinder 53 has a threaded fixing bolt 62 connected internally. The threaded tubes 61 provide stable support and guidance for the fixing bolts 62, preventing misalignment during tightening and ensuring the accuracy and stability of the drill bit 56 position after adjustment. The threaded tubes 61 and fixing bolts 62 are threadedly connected. The length of the threaded tube 61 matches the radial depth of the adjustment cylinder 53, and its inner wall is tapped with internal threads matching the fixing bolts 62. The fixing bolt 62 extends to the inner wall of the adjusting cylinder 53 and is threadedly connected to the rotating shaft 52. The nut of the fixing bolt 62 is located at the outer end of the adjusting cylinder 53. When it is necessary to adjust the spacing between adjacent hole heads 56 according to the row spacing or plant spacing requirements of seed planting, the operator can first loosen the fixing bolt 62 so that the end of the fixing bolt 62 is out of contact with the outer wall of the rotating shaft 52. At this time, the adjusting cylinder 53 can slide along the radial direction of the rotating shaft 52, driving the hole heads 56 to move synchronously. After the hole heads 56 are adjusted to the preset position, the fixing bolt 62 is tightened again so that it passes through the threaded tube 61 and is tightly threadedly connected to the rotating shaft 52, thereby firmly fixing the adjusting cylinder 53 and the rotating shaft 52.
[0025] Working Principle: The operator first places the seeds to be planted on the surface of the placement platform 2 according to the preset arrangement. By pushing the handle 3 and using the moving wheels 4, the equipment is moved to the designated planting area. After starting the equipment, the rotating shaft 52, supported by the movable seat 51, begins to rotate, driving the six sets of drilling heads 56 at the outer end to rotate in a circle around the rotating shaft 52. When the drilling head 56 rotates to its highest point, its tip gradually approaches the seed planting area on the placement platform 2. As the rotating shaft 52 continues to rotate, the tip of the drilling head 56 contacts the planting area and presses downwards, using the hardened tip to form planting holes of the required depth in the soil. During one rotation of the rotating shaft 52, the six sets of drilling heads 56 complete the drilling operation sequentially, achieving multi-group continuous drilling and effectively increasing the drilling rate per unit time. If the row spacing or plant spacing of the holes needs to be adjusted, the operator can first stop the equipment, loosen the fixing bolt 62 on one side of the corresponding adjusting cylinder 53, so that the end of the fixing bolt 62 is disengaged from the rotating shaft 52, and then slide the adjusting cylinder 53 radially along the rotating shaft 52 to move the hole-drilling head 56 to the target position. Then tighten the fixing bolt 62. Through the guiding and fixing effect of the threaded tube 61, the position of the hole-drilling head 56 is ensured to be stable, thereby meeting the needs of different seed planting spacing. When the hole-drilling head 56 is worn or needs to be replaced, simply rotate the hole-drilling head 56 and use the threaded structure to remove it from the protective cover 55. After replacing the new hole-drilling head 56, tighten it again. The above is the working process of the entire device. All contents not described in detail in this manual are existing technologies known to those skilled in the art.
