Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of seed sowing, and particularly relates to a seed sowing device with adjustable seed dropping holes. BACKGROUND

[0002] Seed sowing devices are equipment used for sowing seeds in agricultural production and can be classified into handheld seeders and large-scale seeding machines. Handheld seeders generally have simple structures and are commonly of the hand-rotating type and the air pressure type. The hand-rotating type of handheld seeder is driven by rotating a handle by hand to drive the internal seed-distributing wheel and other devices, so that seeds are discharged from the seed chamber in a certain amount and interval. The air pressure type uses air pressure generated by pressing to blow out seeds. They are small and flexible, suitable for small-area farmland, vegetable gardens or home gardening, convenient for people to sow seeds in different terrains and spaces, can achieve a certain degree of precision sowing, and have low cost and easy operation. Large-scale seeding machines are suitable for large-area planting and can efficiently complete sowing operations.

[0003] Currently, handheld seeders widely used in the field of agricultural planting have some obvious limitations in actual operation. During operation, the user needs to closely cooperate with the operation of both hands, one hand holding the seeder and the other hand performing related operations for sowing, which makes it difficult for the sowing personnel to continuously complete the sowing action during the walking process, greatly slowing down the sowing efficiency. Moreover, in the face of seeds of different sizes, the existing handheld seeders lack flexible adjustment mechanisms and are difficult to accurately adapt to different seed sizes, which may easily result in over-sowing or under-sowing, leading to seed waste or uneven sowing and affecting the overall growth and yield of crops.
