Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to a seed guiding device for an adjustable row spacing radish planter. Background Technology

[0002] In modern agricultural production, radishes are an important economic crop, and their planting efficiency and quality have a significant impact on agricultural profits. The sowing stage is a crucial step in radish cultivation.

[0003] Existing technology, such as patent application number CN202321109749.0, discloses a radish planting device, including two symmetrical fixed plates and connecting rods connected to the two fixed plates. A lever is provided on the outer circumference of the rotating roller, and bearings are provided at the connecting shafts at both ends of the rotating roller. This radish planting device, by setting two fixed plates, using multiple levers on the rotating roller, and cooperating with the planting column, creates holes in the soil below to facilitate radish planting. A tray is installed and used with a storage cylinder to store radish seeds. A sealing plate is correspondingly located at the bottom of the storage cylinder, and a spring is used to repeatedly seal it against the tray. However, in use, the fixed row spacing of this planting device makes it difficult to adapt to different planting needs and soil conditions. In actual planting, different radish varieties have different row spacing requirements, and farmers also need to adjust the row spacing based on soil fertility, planting plans, and other factors. A fixed row spacing planting device limits planting flexibility, reduces land utilization, and lowers planting efficiency.

[0004] In view of this, we propose a seed guiding device for radish planters with adjustable row spacing. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a seed guiding device for an adjustable row spacing radish planter.

[0006] The technical solution of this utility model is:

[0007] An adjustable row spacing radish planter seed guiding device includes a mounting frame. Two moving components are symmetrically slidably mounted within the mounting frame. Each moving component includes two symmetrically arranged side plates, with several diversion funnels positioned between the two side plates. Adjacent diversion funnels are fixed by connecting plates. Two hydraulic cylinders are symmetrically fixedly mounted on both sides of the mounting frame. The hydraulic cylinders on the same side are fixedly connected to the two side plates on the moving components. Two wheel plates are symmetrically fixed on both sides of the bottom of the mounting frame. A soil-covering roller is rotatably mounted between the two wheel plates on the left side, and a straight wheel is rotatably mounted on each of the two wheel plates on the right side. The moving components are driven by the hydraulic cylinders to slide within the mounting frame, thereby flexibly adjusting the distance between adjacent diversion funnels to meet the sowing needs of different row spacings. Simultaneously, the soil-covering roller and straight wheel ensure the stability of the device's movement on the ground and provide preliminary soil treatment after sowing, improving the continuity and efficiency of the sowing operation.

[0008] As a preferred technical solution, each of the diversion funnels has a turntable rotatably installed near the bottom. The outer circumference of the turntable has four dispensing ports arranged in a circular array, and the outer circumference of the turntable is in close contact with the inner wall of the diversion funnel. This allows for quantitative distribution of seeds entering the diversion funnel, ensuring a relatively stable number of seeds discharged from the funnel each time, improving the uniformity and accuracy of sowing, and avoiding uneven planting density caused by too many or too few seeds.

[0009] As a preferred technical solution, a transmission rod rotates between each pair of adjacent diversion funnels, with both ends of the transmission rod coaxially fixed to a turntable inside the diversion funnel. This allows the turntables in multiple diversion funnels to rotate synchronously, ensuring a consistent quantitative distribution rhythm of seeds across all funnels, further improving the overall uniformity and consistency of sowing, and reducing differences in sowing amounts between different areas.

[0010] As a preferred technical solution, a mounting block is fixedly connected to the inner side of one of the side plates, and a drive motor is fixedly installed inside the mounting block. The drive motor is coaxially fixed with the transmission rod. This provides a power source for the rotation of the turntable. Through the stable operation of the drive motor, the rotation speed and rotation angle of the turntable can be precisely controlled, thereby more accurately controlling the seed distribution quantity and sowing frequency to adapt to different sowing operation requirements.

[0011] As a preferred technical solution, the two diversion funnels located at the ends are fixedly connected to the side plate and the mounting block, respectively. This enhances the structural stability of the entire diversion funnel assembly.

[0012] As a preferred technical solution, a main funnel is provided above the mounting frame. Several equally spaced tee pipes are installed at the bottom of the main funnel. Each of the branch funnels has a connecting pipe at its top. The ends of the tee pipes furthest from the main funnel are connected to connecting pipes at the tops of two branch funnels aligned to the left and right, respectively, via corrugated pipes. The connection between the main funnel and the branch funnels via the tee pipes allows for the even distribution of seeds into each branch funnel, ensuring that each branch funnel receives a sufficient seed supply.

[0013] As a preferred technical solution, a support plate is fixedly connected to both ends of the main funnel, and the bottom of the support plate is fixedly connected to the top of the mounting frame. This increases the stability of the main funnel installation.

[0014] As a preferred technical solution, a pull rod is fixedly connected to the top right side of the mounting frame, and a connector for connecting to agricultural machinery is integrally formed on the pull rod. This facilitates a quick and stable connection between the seed guiding device and the agricultural machinery, enabling coordinated operation between the seed guiding device and the agricultural machinery.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses a hydraulic cylinder to drive a moving component to slide within a mounting frame, thereby flexibly adjusting the distance between adjacent diversion funnels to meet the sowing needs of different row spacings. Simultaneously, the inclusion of a soil-covering roller and straight wheels ensures the stability of the device's movement on the ground and provides preliminary soil treatment after sowing, improving the continuity and efficiency of the sowing operation.

[0023] 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.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] An adjustable row spacing radish planter seed guiding device includes a mounting frame 1. Two moving components 2 are symmetrically slidably mounted within the mounting frame 1. Each moving component 2 includes two symmetrically arranged side plates 20, with several diversion funnels 23 positioned between the two side plates 20. Adjacent diversion funnels 23 are fixed by connecting plates 26. Two hydraulic cylinders 10 are symmetrically fixed on both sides of the mounting frame 1, with each hydraulic cylinder 10 on the same side being fixedly connected to one of the two side plates 20 on the moving component 2. Two wheel plates 11 are symmetrically fixed on both sides of the bottom of the mounting frame 1. A soil covering roller 12 is rotatably mounted between the two wheel plates 11 on the left side, and a straight wheel 13 is rotatably mounted on each of the two wheel plates 11 on the right side. The moving components 2 are driven to slide within the mounting frame 1 by the hydraulic cylinders 10, thereby flexibly adjusting the distance between adjacent diversion funnels 23 to meet the seeding requirements of different row spacings. Simultaneously, the soil covering roller 12 and straight wheel 13 ensure the stability of the device's movement on the ground and provide preliminary soil treatment after seeding, improving the continuity and efficiency of the seeding operation.

[0026] like Figure 4 As shown in the preferred embodiment, each diversion funnel 23 has a turntable 27 rotatably mounted near the bottom. The outer circumference of the turntable 27 has four dispensing ports 28 arranged in a circular array, and the outer circumference of the turntable 27 is in close contact with the inner wall of the diversion funnel 23. This allows for quantitative distribution of seeds entering the diversion funnel 23, ensuring a relatively stable number of seeds discharged from the funnel 23 each time, improving the uniformity and accuracy of sowing, and avoiding uneven planting density caused by too many or too few seeds.

[0027] like Figure 3 As shown, in a preferred embodiment, each of the two adjacent diversion funnels 23 is connected by a transmission rod 24, both ends of which are coaxially fixed to the turntable 27 inside the diversion funnel 23. This allows the turntables 27 inside the multiple diversion funnels 23 to rotate synchronously, ensuring a consistent rhythm for the quantitative distribution of seeds by each diversion funnel 23, further improving the overall uniformity and consistency of sowing, and reducing differences in sowing amounts in different areas.

[0028] like Figure 3 As shown, in a preferred embodiment, a mounting block 21 is fixedly connected to the inner side of one of the side plates 20. A drive motor 22 is fixedly installed inside the mounting block 21, and the drive motor 22 is coaxially fixed with the transmission rod 24. This provides a power source for the rotation of the turntable 27. Through the stable operation of the drive motor 22, the rotation speed and rotation angle of the turntable 27 can be precisely controlled, thereby more accurately controlling the seed distribution quantity and sowing frequency to adapt to different sowing operation requirements.

[0029] like Figure 3 As shown, in a preferred embodiment, the two diversion funnels 23 located at the ends are fixedly connected to the side plate 20 and the mounting block 21, respectively. This enhances the structural stability of the entire diversion funnel group 23.

[0030] like Figure 1 and Figure 2 As shown in the preferred embodiment, a main funnel 4 is provided above the mounting frame 1. Several equally spaced T-tubes 41 are installed at the bottom of the main funnel 4. A connecting pipe 25 is installed at the top of each diversion funnel 23. The ends of the T-tubes 41 furthest from the main funnel 4 are connected to the connecting pipes 25 at the tops of two diversion funnels 23 aligned to the left and right, respectively, via corrugated pipes 3. The main funnel 4 is connected to the diversion funnels 23 via the T-tubes 41, enabling the seeds to be evenly distributed into each diversion funnel 23, ensuring that each diversion funnel 23 receives a sufficient supply of seeds.

[0031] like Figure 1 As shown, in a preferred embodiment, a support plate 40 is fixedly connected to both ends of the main funnel 4, and the bottom of the support plate 40 is fixedly connected to the top of the mounting frame 1. This increases the stability of the main funnel 4 installation.

[0032] like Figure 1 As shown in the preferred embodiment, a pull rod 5 is fixedly connected to the top right side of the mounting frame 1. The pull rod 5 has an integrally formed connector 50 for connecting to agricultural machinery. This facilitates a quick and stable connection between the seed guiding device and the agricultural machinery, enabling coordinated operation between the seed guiding device and the agricultural machinery.

[0033] When using the adjustable row spacing radish planter seed guiding device of this utility model:

[0034] The seed guiding device is securely connected to the agricultural machinery via the connector 50 on the pull rod 5, and is moved by the traction device of the agricultural machinery. Before sowing, according to the required row spacing, the hydraulic cylinders 10 on the left and right sides of the mounting frame 1 are activated. The hydraulic cylinders 10 push the moving component 2 to slide within the mounting frame 1. Since the diversion funnels 23 between the upper side plates 20 of the moving component 2 are fixed by the connecting plate 26, the spacing between adjacent diversion funnels 23 can be flexibly adjusted to complete the row spacing setting.

[0035] During operation, seeds are poured into the main funnel 4, which is connected to the connecting pipe 25 at the top of the distribution funnel 23 via a three-way pipe 41 at its bottom, distributing the seeds to each distribution funnel 23. The drive motor 22 inside the mounting block 21 starts, driving the transmission rod 24, which is coaxially fixed to it, to rotate. The transmission rod 24 then drives the turntable 27 in the adjacent distribution funnel 23 to rotate synchronously. During rotation, the dispensing port 28 on the outer circumference of the turntable 27 quantitatively collects the seeds entering the distribution funnel 23. When the dispensing port 28 rotates to its lowest point, the seeds are discharged through the dispensing port 28, achieving quantitative sowing.

[0036] During the movement of the device, the straight wheel 13 on the right wheel plate 11 provides support and guidance, ensuring that the device moves stably along a straight line; the soil covering roller 12 between the left wheel plates 11 performs preliminary soil covering after the seeds are sown, completing the continuous process of sowing and ensuring that the radish seeds can be sown into the soil with appropriate row spacing and uniform distribution.

[0037] 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. The scope of protection of this utility model is defined by the appended claims and their equivalents.
