Technical Field

[0001] The utility model relates to the technical field of seeders, in particular to an adjustable multi-row seeder. Background Technique

[0002] Agricultural machinery is a general term for various mechanical equipment and tools used in the agricultural production process. They are mainly used to improve agricultural production efficiency, reduce labor intensity, and improve crop quality. Among them, a seeder is an agricultural machine used to evenly distribute seeds into the field. The design purpose of the seeder is to improve seeding efficiency and ensure that seeds are sown at an appropriate depth and spacing to promote the healthy growth of crops.

[0003] After retrieval, it is found that the Chinese patent with the application number 201720554847.3 discloses a precision seeder for small-grain vegetable seeds with adjustable row spacing, including a cart. Two wheels fixed by a first rotating shaft are arranged at the lower end of the cart. Both ends of the first rotating shaft are fixed to the cart through bearings. A second rotating shaft is also fixed to the cart bracket obliquely above the first rotating shaft through a bearing. Four precision seeders with adjustable relative distances are fixed on the second rotating shaft. The openings at the upper ends of the precision seeders are detachably and fixedly connected to the seed bin through hoses. An adjusting rod is also arranged on the cart bracket in front of the second rotating shaft. Both ends of the adjusting rod are respectively fixed in the strip-shaped holes of the cart brackets at both ends of the cart. Four furrow openers corresponding to the precision seeders one by one are arranged on the adjusting rod. Each furrow opener is fixedly arranged on the adjusting rod with adjustable relative distance left and right. The utility model provides a precision seeder for small-grain vegetable seeds with adjustable row spacing, which can sow multiple rows, has high seeding efficiency, adjustable row spacing, and adjustable seeding depth.

[0004] The above-mentioned utility model has the following problems:

[0005] The seed bin of this device is divided into multiple parts. When loading seeds, it is necessary to pour the seeds one by one, which is rather troublesome. Moreover, the seed bin is relatively small and shallow, and the seeds in the seed bin may fly out during mobile seeding.

[0006] When encountering relatively hard ground, the furrow opener may be damaged, and the furrowing efficiency is not high either.

[0007] Therefore, those skilled in the art provide an adjustable multi-row seeder to solve the problems raised in the above background technique. Content of the Utility Model

[0008] The purpose of the utility model is to provide an adjustable multi-row seeder to solve the problems raised in the above background technique.

[0009] To achieve the above purpose, the utility model provides the following technical solutions:
