This type of seeder usually has multiple sowing units and can complete multiple row sowing operations at one time, thereby improving sowing efficiency. Multi-row seeders need to use a row spacing adjustment structure to adjust the distance between sowing units.

[0003] Based on existing solutions and actual production and processing, the current row spacing adjustment structure of multi-row seeders still has some problems. For example, when adjusting the row spacing of the seeding unit, the seeding unit is adjusted through the guide rail. Since the installation of the guide rail is difficult and costly, it affects the adjustment effect of the row spacing of the seeding unit. Therefore, this utility model provides a multi-row seeder that includes a row spacing adjustment structure to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-row seeder with a row spacing adjustment structure to solve the problem mentioned in the background art that when adjusting the row spacing of the seeding unit, the seeding unit is adjusted via a guide rail. However, the guide rail is difficult to install and has a high cost, which affects the adjustment effect of the row spacing of the seeding unit.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-row seeder with a row spacing adjustment structure, comprising a seeder body, a first motor at its front end, a movable frame connected to the output end of the first motor, and a roller on the inner side of the movable frame;

[0006] Also includes:

[0007] The mounting rod is installed on the inner side of the movable frame, and the outer side of the mounting rod is connected to the middle side of the roller. A movable structure is installed on the outer side of the roller. The adjustment structure includes a mounting block, a fixed rod, a movable rod, and a push block. The mounting block is installed on the outer side of the middle part of the roller, and a fixed rod is connected to the lower side of the mounting block. A movable rod is provided at the lower end of the roller, and a push block is connected to the outer side of the movable rod.

[0008] A partition plate is movably installed inside the drum, and an installation structure is connected to the outer side of the partition plate. The installation structure includes a limiting rod, a spring, and a moving rod. The limiting rod is connected to the rear end of the partition plate, and the moving rod is connected to the front side of the partition plate. A spring is provided on the outer side of the moving rod.

[0009] Preferably, a fixed frame is fixedly connected to the upper side of the movable frame, and a second motor is provided on the front left side of the movable frame, and the output end of the second motor is connected to the mounting rod;

[0010] A seeding box is fixedly installed at the upper end of the fixed frame, and a connecting pipe is connected to the lower side of the seeding box. A connecting plate is fixedly installed at the lower side of the connecting pipe. A fixing block is connected to the left end of the fixed frame, and a connecting block is connected inside the fixing block.

[0011] Preferably, a fixed plate is connected to the inner side of the roller, and a movable plate is connected inside the fixed plate, and the lower side of the roller is connected to the movable rod through a bearing.

[0012] Preferably, the fixing rod and the mounting block are connected by a thread, and the mounting blocks are symmetrically distributed about the center line of the roller.

[0013] Preferably, the limiting rod and the partition plate are connected by a thread, the partition plate is distributed at equal angles about the center point of the roller, and the partition plate and the moving rod are connected by a snap-fit ​​connection.

[0014] Preferably, the connecting plate and the roller are fitted together and provide a sealing effect between the partition plates.

[0015] Preferably, the fixed block and the connecting block are telescopically sliding connected, and the cross-sectional shape of the connecting block is an "L" shape.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the row spacing adjustment structure of the multi-row seeder is provided with a movable structure that can adjust the row spacing of the seeding unit, and is also provided with an installation structure that can adjust the space inside the seeding unit, thereby adjusting the seeding row spacing of the seeding unit.

[0017] 1. By rotating the fixed rod, the fixed rod is threadedly connected to the lower side of the mounting block, thereby moving the fixed rod downward in the middle of the mounting block. This causes the fixed rod to separate from the lower side of the mounting rod. Rotating the movable rod causes it to rotate under the roller via the bearing, thereby causing the push block threadedly connected to the movable rod to push the roller on the outer side of the middle of the mounting rod to slide inward. This causes the roller to drive the fixed plate and the movable plate to slide in and out, facilitating the adjustment of the row spacing between the rollers.

[0018] 2. By installing the partition plate inside the drum, loosen the moving rod, and let the spring drive the moving rod to slide backward, so that the moving rod is engaged with the front side of the partition plate. Rotate the limiting rod to make the limiting rod threaded at the rear end of the drum, so that the limiting rod is threaded with the rear side of the partition plate. This makes it easy to install the partition plate, thereby making it easy to adjust the distance between the partition plates, and thus making it easy to adjust the sowing row spacing.

[0019] 3. By starting the second motor, the second motor drives the mounting rod to rotate on the inner side of the left end of the movable frame. This causes the mounting rod to drive the roller to rotate on the inner side of the connecting plate. In turn, the roller drives the seeds on the inner side of the separator plate to rotate to the lower inner side of the connecting plate. The seeds then fall to the ground through the perforated structure on the lower side of the connecting plate, making it convenient for sowing. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-8 This utility model provides a technical solution: a multi-row seeder with a row spacing adjustment structure, comprising a seeder body 1, a first motor 2, a movable frame 3, a mounting rod 4, a roller 5, a separator plate 6, a fixed frame 7, a connecting pipe 8, a seed box 9, a second motor 10, a mounting block 11, a fixed rod 12, a limiting rod 13, a fixed plate 14, a movable rod 15, a push block 16, a spring 17, a moving rod 18, a moving plate 19, a connecting plate 20, a fixed block 21, and a connecting block 22. In operation, the specific details are as follows... Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a roller 5 is installed on the outer side of the mounting rod 4, and a mounting block 11 is fixedly installed on the outer side of the middle part of the roller 5. A fixed rod 12 is movably connected to the lower side of the mounting block 11. By manually rotating the fixed rod 12 installed on the lower side of the middle part of the mounting block 11, the fixed rod 12 is threadedly connected to the lower side of the middle part of the mounting block 11 under the rotation. Thus, under the thread action between the mounting block 11 and the fixed rod 12, the fixed rod 12 moves downward. Then, under the movement of the fixed rod 12, the fixed rod 12 separates from the lower side of the mounting rod 4. Then, by manually rotating the movable rod 15 on the outer side of the lower end, the movable rod 15 rotates on the roller 5 through the bearing. Thus, under the rotation of the movable rod 15, the movable rod 15 is threadedly connected to the inner side of the push block 16. Then, the thread between the movable rod 15 and the push block 16 is threaded. Under the action of the push block 16, the roller 5 is pushed to slide inward. Under the action of the roller 5 sliding inward, the fixed plate 14 and the moving plate 19 slide in and out. Under the action of the roller 5 sliding inward, the roller 5 drives the fixed frame 7 to slide inward. Under the action of the fixed frame 7 sliding inward, the fixed block 21 and the connecting block 22 slide in and out. After the distance between the rollers 5 is adjusted to a suitable position, the fixed rod 12 is manually rotated. Under the action of the rotation, the fixed rod 12 is threaded on the lower side of the mounting block 11. Under the action of the thread between the fixed rod 12 and the mounting block 11, the fixed rod 12 moves upward. Under the action of the upward movement of the fixed rod 12, the fixed rod 12 is threaded on the lower side of the mounting rod 4, which facilitates the adjustment of the row spacing between the rollers 5.

[0031] Specific examples Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, a limiting rod 13 is connected to the outer rear end of the roller 5, a partition plate 6 is movably connected to the front side of the limiting rod 13, a spring 17 is fixedly installed on the outer front end of the roller 5, and a moving rod 18 is connected through the middle of the spring 17. Pulling the moving rod 18 forward causes it to slide forward on the front side of the roller 5, thereby causing the moving rod 18 to drive the spring 17 to extend. The partition plate 6 is placed inside the roller 5. Releasing the moving rod 18 causes the spring 17 to drive the moving rod 18 to slide backward on the front side of the roller 5 under the elastic action of the spring 17. Under sliding action, the moving rod 18 is engaged with the front side of the partition plate 6. The limiting rod 13 is manually rotated, so that under the rotation action, the limiting rod 13 is threadedly connected to the outer rear end of the roller 5. Under the thread action between the limiting rod 13 and the roller 5, the limiting rod 13 moves forward. Then, under the forward movement of the limiting rod 13, the limiting rod 13 is threadedly connected to the rear side of the partition plate 6, which facilitates the installation of the partition plate 6. Furthermore, by setting multiple partition plates 6 inside the roller 5, the angle between the partition plates 6 changes, thereby changing the sowing row spacing on the ground, which facilitates the adjustment of the sowing row spacing.

[0032] Specific examples Figure 1 , Figure 2 and Figure 4 As shown, a first motor 2 is installed at the front end of the seeder body 1. The output end of the first motor 2 is connected to a movable frame 3. A fixed frame 7 is fixedly installed on the upper side of the movable frame 3. When the first motor 2 is started, the movable frame 3 connected to the output end of the first motor 2 rotates inside the seeder body 1. The rotation of the movable frame 3 causes the roller 5 to rotate downward. The second motor 10 installed on the front left side of the movable frame 3 is started, causing the mounting rod 4 connected to the output end of the second motor 10 to rotate. The rotation of the mounting rod 4 causes the roller 5 to rotate inside the connecting plate 20. The seeds inside the seed box 9 enter the inner side of the partition plate 6 through the connecting pipe 8. The roller 5 drives the partition plate 6 to rotate, causing the seeds inside the partition plate 6 to rotate to the lower inner side of the connecting plate 20. The seeds then fall onto the ground through the perforated structure on the lower side of the connecting plate 20, facilitating seed sowing.
