Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to an adjustable plant spacing seeder. Background Technology

[0002] In the sowing process, a manual seeder is an agricultural tool that enables precise sowing. The main application scenarios for manual seeders are...

[0003] 1. Conventional sowing:

[0004] In small-scale farmland, mountain terraces, or plots of land inaccessible to machinery, manual seeders can be used directly for initial sowing, such as planting crops like corn, beans, and vegetables. Their advantages include flexible operation, adaptability to complex terrains such as slopes and scattered plots, and no reliance on mechanized equipment.

[0005] 2. Replanting

[0006] For situations where seedlings are missing or rows are broken after initial sowing, manual seeders can accurately resow seeds, avoiding the cost of large-scale resowing. If seeds are destroyed by heavy rain, have low germination rates, or are missed by mechanical sowing, manual seeders can quickly replant seedlings.

[0007] 3. Sowing of special crops or experimental fields

[0008] For scientific research experimental fields, rare crops, or crops that require special planting densities, manual seeders can adjust the seeding amount and spacing as needed to meet individual requirements.

[0009] The existing manual playback devices have the following shortcomings:

[0010] 1) Existing manual seeders do not have a seed hole positioning function, so they cannot achieve precise plant spacing control.

[0011] 2) When it is necessary to test the growth of a crop under different plant spacing or planting density, the existing manual seeding device cannot achieve the purpose of accurately and quickly adjusting the plant spacing.

[0012] To address the aforementioned shortcomings, there is an urgent need to design a seeder that can quickly adjust the plant spacing. Utility Model Content

[0013] In view of this, the purpose of this utility model is to provide an adjustable plant spacing seeder, which has a seed hole positioning function to achieve precise and rapid adjustment of plant spacing.

[0014] This utility model solves the above-mentioned technical problems through the following technical means:

[0015] An adjustable plant spacing seeder includes a hollow rod body, a seed chamber connected to the interior of the rod body at the top, and a sowing mechanism and a hole-fixing mechanism at the bottom of the rod body. The hole-fixing mechanism includes multiple hole-fixing columns, a sleeve fitted on the bottom of the rod body, and a positioning component connected to the sleeve for installing the multiple hole-fixing columns. The position of the multiple hole-fixing columns on the positioning component is adjustable.

[0016] Furthermore, the positioning component includes a crossbar fixedly connected to a sleeve at one end, and a plurality of sliders A sleeved on the crossbar. Each slider A is provided with a pin mechanism and a locking screw. The slider A is provided with a threaded hole that engages with the locking screw. The pin mechanism includes a pin, and the top of the locating column is connected to the bottom of the pin.

[0017] As a parallel technical solution, the positioning component includes an X-shaped telescopic chain with one end connected to a sleeve. The X-shaped telescopic chain is a chain-like structure formed by multiple X-shaped units connected in series. Each X-shaped unit consists of two cross-arranged connecting rods that are hinged to each other in the middle by a hinge shaft A. Adjacent X-shaped telescopic chains are connected by two hinge shafts B, which are respectively set at the ends of the connecting rods. The lower hinge shaft B is fixedly connected to a light rod and the cavitation column, and the upper hinge shaft B is provided with a through hole. The light rod is inserted into the through hole. When the X-shaped telescopic chain extends or retracts, the upper hinge shaft B can slide up and down along the light rod.

[0018] Furthermore, the sleeve is provided with a lead screw and nut mechanism, which includes a threaded rod whose bottom end is fixedly connected to the sleeve, a spring and a slider B sleeved on the threaded rod, and a nut that is threadedly engaged with the threaded rod. The end of the X-shaped telescopic chain connected to the sleeve includes two connecting rods, one end of which is hinged to the lower part of the sleeve, and the other end of which is hinged to the slider B. The nut, slider B, and spring are arranged sequentially on the threaded rod from top to bottom. Rotating the nut can adjust the telescopic length of the X-shaped telescopic chain.

[0019] Furthermore, the seeding mechanism includes a wedge-shaped seed outlet located at the bottom of the rod and a wedge-shaped cover plate covering the seed outlet. The upper part of the wedge-shaped cover plate is hinged to the rod. A swing arm for controlling the opening and closing of the wedge-shaped cover plate is fixedly connected to the wedge-shaped cover plate. One end of the swing arm is fixedly connected to the wedge-shaped cover plate, and a push plate is provided at the other end of the swing arm.

[0020] Furthermore, an arc-shaped partition plate is provided on the top of the wedge-shaped cover plate, and an oblong hole communicating with the interior of the rod is provided at the position of the partition plate on the lower part of the rod body, and one end of the partition plate can be inserted into the oblong hole.

[0021] Furthermore, the sleeve is provided with a positioning hole, and the lower part of the rod is provided with multiple positioning pins. When the sleeve moves along the rod, the positioning hole can pass through the multiple positioning pins in sequence.

[0022] The beneficial effects of this utility model are:

[0023] This utility model discloses an adjustable-spacing seeder, comprising a hollow rod body. A seed chamber, communicating with the interior of the rod body, is located at the top of the rod body. A sowing mechanism and a hole-fixing mechanism are located at the bottom of the rod body.

[0031] The present invention will now be described in detail with reference to the accompanying drawings:

[0032] Example 1: An adjustable plant spacing seeder

[0033] like Figures 1 to 3 , Figure 6As shown, an adjustable-spacing planter in this embodiment includes a hollow rod 1. The top of the rod 1 is provided with a seed chamber 2 that communicates with the interior of the rod. In this embodiment, the upper part of the seed chamber 2 is provided with a handle 1A for easy gripping. The lower part of the rod 1 is provided with a sowing mechanism and a hole-fixing mechanism. The sowing mechanism includes a wedge-shaped seed outlet 10 located at the bottom of the rod and a wedge-shaped cover plate 11 covering the seed outlet. The upper part of the wedge-shaped cover plate 11 is hinged to the rod. A swing arm 12 for controlling the opening and closing of the wedge-shaped cover plate is fixedly connected to the wedge-shaped cover plate 11. One end of the swing arm 12 is fixedly connected to the wedge-shaped cover plate 11, and the other end of the swing arm 12 is provided with a push plate 13. The hole-fixing mechanism includes multiple hole-fixing columns 3, a sleeve 4 sleeved on the lower part of the rod, and a positioning component connected to the sleeve 4 for installing the multiple hole-fixing columns 3. The position of the multiple hole-fixing columns on the positioning component is adjustable. Specifically, the positioning assembly includes a crossbar 5 fixedly connected to the sleeve 4 at one end, and a plurality of sliders A6 sleeved on the crossbar 5. The crossbar 5 is provided with a scale, and each slider A6 is provided with a pin mechanism and a locking screw 7. The slider A6 is provided with a threaded hole that engages with the locking screw. The pin mechanism includes a pin 8 and a pin seat 9, and the top of the locating post 3 is connected to the bottom of the pin 8.

[0034] The working principle of the adjustable plant spacing seeder in this embodiment:

[0035] Before sowing, the position of the slider A6 on the horizontal bar 5 is adjusted, thereby adjusting the position of the hole-fixing column 3 to determine the distance between the seed holes. During sowing, the seeds in the seed chamber 2 fall down the hollow rod 1 into the seed outlet 10. When the operator holds the sowing device handle and inserts it downward into the seed hole, the push plate 13 will cause the swing arm 12 to swing upward relative to the rod 1 due to the resistance of the ground, thereby opening the wedge-shaped cover 11 at the seed outlet 10, allowing the seeds to fall into the seed hole. Because the adjustable spacing sowing device of this utility model is equipped with a hole-fixing mechanism, after sowing, a positioning hole made by the hole-fixing column will appear in front of the sown seed hole. Through this positioning hole, the position of the seed hole for the next sowing can be accurately determined.

[0036] Example 2: An adjustable plant spacing seeder

[0037] like Figure 4 and 5As shown in this embodiment, an adjustable-spacing planter includes a hollow rod 1. A seed chamber 2, communicating with the interior of the rod, is located at the top of the rod 1. In this embodiment, a handle for easy gripping is provided on the upper part of the seed chamber 2. A sowing mechanism and a hole-fixing mechanism are provided at the lower part of the rod 1. The sowing mechanism includes a wedge-shaped seed outlet 10 located at the bottom of the rod and a wedge-shaped cover plate 11 covering the seed outlet. The upper part of the wedge-shaped cover plate 11 is hinged to the rod. A swing arm 12 for controlling the opening and closing of the wedge-shaped cover plate 11 is fixedly connected to the wedge-shaped cover plate 11. One end of the swing arm 12 is fixedly connected to the wedge-shaped cover plate 11, and a push plate 13 is provided at the other end of the swing arm 12. The hole-fixing mechanism includes multiple hole-fixing posts 3, a sleeve 4 fitted onto the lower part of the rod, and a positioning assembly connected to the sleeve 4 for installing the multiple hole-fixing posts 3. The positions of the multiple hole-fixing posts on the positioning assembly are adjustable. Specifically, the positioning component includes an X-shaped telescopic chain with one end connected to the sleeve 4. The X-shaped telescopic chain is a chain-like structure formed by multiple X-shaped units connected in series. Each X-shaped unit consists of two cross-arranged connecting rods 14 hinged together at the middle by a hinge shaft A. Adjacent X-shaped telescopic chains are connected by two hinge shafts B15 respectively located at the upper and lower ends of the connecting rods 14. The lower hinge shaft B15 is fixedly connected to a smooth rod 16 and the cavitation column 3, while the upper hinge shaft B15 has a through hole 17 into which the smooth rod 16 is inserted. When the X-shaped telescopic chain extends or retracts, the upper hinge shaft B15 can slide up and down along the smooth rod. In this embodiment, the cavitation column 3 and the smooth rod 16 are designed as a single, integrated unit. The sleeve 4 is equipped with a lead screw and nut mechanism, which includes a threaded rod 18 fixedly connected to the sleeve 4 at its bottom end, a spring 19 and a slider B20 sleeved on the threaded rod 18, and a nut 21 threadedly engaged with the threaded rod 18. The end of the X-shaped telescopic chain connected to the sleeve includes two connecting rods, one end of which is hinged to the lower part of the sleeve, and the other end of which is hinged to the slider B. The nut 21, slider B20, and spring 19 are arranged sequentially on the threaded rod 18 from top to bottom. The telescopic length of the X-shaped telescopic chain can be adjusted by rotating the nut 21.

[0038] The working principle of the adjustable plant spacing seeder in this embodiment 2 is as follows: Before sowing, adjust the position of the nut 21 on the threaded rod 18. The downward movement of the nut 21 pushes the slider B20 downward. When the slider B moves downward, the X-shaped telescopic chain becomes longer, and the distance between adjacent planting holes 3 increases, thus achieving the purpose of quickly adjusting the plant spacing. During sowing, the seeds in the seed chamber 2 fall into the seed outlet 10 along the hollow rod 1. When the operator holds the seeder handle and inserts it downward into the planting hole, the push plate 13 will cause the swing arm 12 to swing upward relative to the rod 1 due to the resistance of the ground, thereby causing the wedge-shaped cover plate 11 at the seed outlet 10 to open, allowing the seeds to fall into the planting hole.

[0039] As a further improvement to the two implementation schemes described above, an arc-shaped partition plate 22 is provided at the top of the wedge-shaped cover plate 11, and an oblong hole 23 communicating with the interior of the rod is provided at the position corresponding to the partition plate 22 at the lower part of the rod. One end of the partition plate 22 can be inserted into the oblong hole 23. The partition plate 22 is used to block the hollow channel inside the rod for seeds to slide down. The advantage of setting the partition plate 22 is particularly obvious when the seeds are relatively small. For example, when sowing small mung beans, when the wedge-shaped cover plate 11 is opened, the partition plate will be inserted into the oblong hole 23 to cut off the channel inside the rod, so that the seeds in the channel are separated. Therefore, when the seeder is lifted upward, the seeds above the partition plate will not continue to fall down into the seed hole, so that the number of seeds sown into the seed hole will not be too large.

[0040] As a further improvement to the above two implementation schemes, the sleeve is provided with a positioning hole 24, and the lower part of the rod is provided with multiple positioning pins 25. A spring is installed between the positioning pins 25 and the sleeve. When the sleeve moves along the rod, the positioning hole 24 can pass through the multiple positioning pins 25 in sequence. When it is necessary to adjust the height of the locating column 3, the positioning pin 25 can be pressed down to separate the positioning pin 25 from the positioning hole 24 on the sleeve, so that the sleeve can move up and down to adjust the height of the locating column 3.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
