Description

[0002] During agricultural sowing, multiple rows of sowing pits are dug in the farmland, and then seeds are sown in the sowing pits one by one, and then soil is covered on the seeds. When sowing seeds, a seeder is usually used. The seeder can sow a fixed amount of seeds at a time, which can improve the uniformity of sowing. Some sowing devices have multiple seeders, which can sow seeds into multiple rows of sowing pits at the same time, which can improve the sowing efficiency. However, due to the different planting requirements of different crops, the distances between adjacent sowing pits of different crops are different. The sowing device with multiple sowing mechanisms can only sow in sowing pits with fixed pit distances, which is less practical and needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0025] The present application embodiment provides an agricultural sowing device, such as Figure 1-Figure 6 As shown, it includes a sowing mechanism 1, a cross-folding telescopic rod 4, a pair of support plates 3, etc.

[0026] Specifically, there are multiple sowing mechanisms 1, all of which are slidably arranged on a first sliding rod 2, the first sliding rod 2 is arranged between a pair of support plates 3, a pair of rollers 301 are arranged at the bottom of the support plates 3, the outermost sowing mechanism 1 is connected to a support plate 3, and multiple first hinge shafts 401 located in the middle part of the cross-folding telescopic rod 4 in the width direction are respectively connected to multiple sowing mechanisms 1, and the first hinge shaft 401 connected to another outermost sowing mechanism 1 is connected to the telescopic end of a telescopic mechanism 5, the telescopic mechanism 5 is fixed to the support plate 3, and the telescopic direction of the telescopic end of the telescopic mechanism 5 is parallel to the first sliding rod 2. When the telescopic end of the telescopic mechanism 5 is pushed out, the cross-folding telescopic rod 4 contracts and drives the multiple sowing mechanisms 1 to get closer, thereby reducing the distance between the sowing mechanisms 1; when the telescopic end of the telescopic mechanism 5 is retracted, the cross-folding telescopic rod 4 extends, thereby driving the multiple sowing mechanisms 1 to spread out and increasing the distance between the sowing mechanisms 1.

[0027] In actual use, first dig multiple rows of sowing pits in the farmland, then place the sowing device in the farmland, adjust the distance between multiple sowing mechanisms 1 by adjusting the push-out distance of the telescopic end of the telescopic mechanism 5 to match the distance between each row of sowing pits, and then push the sowing device to align the seed release port of the sowing mechanism 1 with the sowing pit to release the seeds.

[0028] For details, see Figure 6The sowing mechanism 1 includes a toothed disc 101 and a housing. The housing includes an arc segment 102 and a rectangular segment 103. The toothed disc 101 is arranged in the arc segment 102, and the inner diameter of the arc segment 102 matches the toothed disc 101. The bottom of the arc segment 102 has a first notch 1021, and the arc segment 102 has a second notch 1022 on the side facing the cross-folding telescopic rod 4. The rectangular segment 103 is connected to the second notch 1022. The rectangular segment 103 is slidably connected to the first sliding rod 2 through a connecting plate 1031. The first notch 1021 is connected to a discharge pipe 104. The toothed disc 101 is connected to a rotating mechanism, and the rotating mechanism is used to drive the toothed disc 101 to rotate. When in use, seeds are placed in the rectangular segment 103 of the housing, and the seeds will fall into the tooth grooves of the toothed disc 101. Then the rotating mechanism is controlled to drive the toothed disc 101 to rotate. When the tooth grooves are aligned with the first notch 1021, the seeds in the tooth grooves can fall out along the discharge pipe 104.

[0029] For details, see Figure 1 , Figure 2 , Figure 6 , the rotating mechanism includes a spline shaft 6 and a driving motor 601, and a through hole 1023 is provided on the arc segment 102 for accommodating the spline shaft 6. The toothed disc 101 is coaxially arranged on the spline shaft 6, and the two ends of the spline shaft 6 are respectively connected to a pair of support plates 3 for rotation, and the spline shaft 6 is connected to the output shaft of the driving motor 601. When sowing is required, the driving motor 601 is controlled to drive the spline shaft 6 to rotate, and multiple toothed discs 101 can be driven to rotate at the same time, so that the seeds in multiple shells are released synchronously. More specifically, one end of the spline shaft 6 is connected to a first gear 602, and the first gear 602 is meshed and connected with a second gear 603, and the second gear 603 is connected to the output shaft of the driving motor 601, and the number of teeth of the first gear 602 is greater than the number of teeth of the second gear 603. The first gear 602 is driven to rotate by the second gear 603, that is, the large gear is driven to rotate by the small gear, so as to facilitate the control of the speed of the spline shaft 6, and prevent the spline shaft 6 from rotating too fast, resulting in too many seeds released.

[0030] Preferably, see Figure 2 , a scraper 7 is provided at one end of the support plate 3 near the cross-folding telescopic rod 4. When a sowing pit is dug in the farmland, the excavated soil can be piled at the rear side of the sowing pit. After sowing by the sowing device, when the device is pushed forward, the scraper 7 can scrape the soil into the sowing pit. For details, refer to Figure 3 , Figure 4A first vertical plate 701 is provided at both ends of one side of the scraper 7, and a first connection hole 7011 is provided on the first vertical plate 701. A second vertical plate 302 is provided at one end of the support plate 3 close to the cross-folding telescopic rod 4, and a plurality of second connection holes 3011 matching the first connection hole 7011 are arranged in an array along the vertical direction on the second vertical plate 302, and the first connection hole 7011 and the second connection hole 3011 are connected by pins or screws. By connecting the first connection hole 7011 with the second connection holes 3011 of different heights, the distance between the bottom of the scraper 7 and the bottom of the roller 301 can be adjusted to adapt to seeding pits of different heights.
