[0043] It should be noted that there are three sets of card slots 310, and each set of card slots 310 corresponds to each set of storage buckets 303, which makes it easy to fix the storage buckets 303 when changing seeds.

[0044] In a preferred embodiment, the rotating shaft 301 passes through the support plate 1, the feed hopper 304 passes through the upper end of the storage tank 303, the discharge pipe 305 passes through the lower end of the storage tank 303, and the discharge pipe 305 passes through the pallet 302.

[0045] In a preferred embodiment, the discharge hole 306 penetrates through the support plate 1, and there are two sets of discharge holes 306 and two sets of discharge pipes 305.

[0046] Example 2:

[0047] Based on Example 1, in order to further improve the convenience of seed feeding, the support plate 1 is provided with an adjustment structure;

[0048] As a preferred embodiment, the adjustment structure includes a feeding cylinder 403 arranged at the bottom of the support plate 1 for feeding seeds;

[0049] In a preferred embodiment, the adjustment structure further includes: a side plate 404, fixedly disposed on one side of the feed cylinder 403, for driving the feed cylinder 403 to move; a limiting groove 401, formed at the bottom of the support plate 1, for limiting the side plate 404, and one end of the side plate 404 is slidably connected to the limiting groove 401; a telescopic hose 402, one end fixedly disposed on the support plate 1, and the other end fixedly disposed at the upper end of the feed cylinder 403, for conveying seeds to the feed cylinder 403 through the feed hole 306; and a threaded rod 405, rotatably connected to the bottom of the support plate 1, for driving the side plate 404 to move, and the side plate 404 is threadedly connected to the threaded rod 405.

[0050] It should be noted that the limiting groove 401 is T-shaped, one end of the side plate 404 is T-shaped to fit the limiting groove 401, and the side plate 404 is L-shaped.

[0051] In a preferred embodiment, the feeding cylinder 403 is provided with two sets, and one end of the telescopic hose 402 is connected to the feeding hole 306;

[0052] In a preferred embodiment, the threaded rod 405 is provided with two sets of reverse threads, and the side plate 404 is provided with two sets, which are respectively provided at both ends of the threaded rod 405.

[0053] Working Principle: In use, firstly, the support plate 1 is connected to the drive equipment via bolts through the connecting plate 2. Then, different seeds are placed into the three sets of storage bins 303 through three sets of feeding hoppers 304. When it is necessary to change the seeds for sowing, pull the locking post 308 to one side, allowing it to slide on the fixing plate 307 and compress the spring 309. When one end of the locking post 308 disengages from the slot 310, rotate the shaft 301 on the support plate 1. The shaft 301 drives the support plate 302 to rotate, which in turn moves the storage bins 303. When the desired seeds are found in one set of storage bins 303, release the locking post 308. The spring 309 rebounds, causing one end of the locking post 308 to engage with the corresponding slot 310 in the storage bin 303, thus fixing the storage bin 303. This allows the operator to easily adjust the seed type in the desired set of storage bins 303 according to actual needs. Seeds can be quickly changed according to different areas of the field or different crop needs to achieve multi-variety sowing. Then, the threaded rod 405 is turned on the support plate 1 according to the spacing of the furrows in the field. The threaded rod 405 drives the two sets of side plates 404 to slide in opposite directions on the limiting groove 401 through two sets of reverse threads. The two sets of side plates 404 drive the two sets of feeding cylinders 403 to move. When the spacing between the two sets of feeding cylinders 403 is adjusted according to the spacing of the sowing furrows in the field, it can ensure that the sowing spacing is precisely matched with the spacing of the sowing furrows in the field, avoiding crop growth restriction or resource waste caused by improper spacing. Then, the drive device is turned on, and the drive device drives the feeding cylinders 403 to move forward at a uniform speed. The seeds fall through the two sets of discharge pipes 305 onto the two sets of discharge holes 306, and through the two sets of discharge holes 306 onto the two sets of telescopic hoses 402, and through the two sets of telescopic hoses 402 into the sowing furrows in the field by the two sets of feeding cylinders 403.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
