Universal seeder for machine transplanting and throwing

Abstract

The invention relates to a seeder used for mechanical transplanting and seedling throwing, which is composed of a double-layer screen mesh (2), a wire hoop (3), a spring (6), a surrounding plate (4), a seeds case (1), a positioning foot and a handle (10); the same mesh openings (7) which are uniformly distributed in a delta shape are arranged on the screen mesh, the mesh openings on the double-layer screen mesh are mutually matched and corresponded one by one, the size and the distribution rule of the mesh opening are matched with a throwing tray pot aperture, the mesh opening is in a rectangular shape, width of the mesh opening is matched with the width of the seed, two rice seeds can be accommodated in the length direction of the mesh opening, depth of the mesh opening is matched with the thickness of the seeds, and the long edge is parallel with the seed case; the upper port of the mesh opening is less than lower port of the mesh opening; an upwardly projected seed backflow obstruct barrier (11) is positioned at the junction of the edge of the seed case of the upper layer screen mesh and the boundary of the mesh opening, the spring is positioned at intermediate part of the bottom of the seed case, each screen mesh is fixedly connected to one end of the spring, an operation handle (5) used for compressing the spring is arranged on the lower layer screen mesh; and a smooth plane capable of pasting with an adhesive tape is arranged on the upper surface of the upper layer screen mesh. The seeder has dual functions of throwing seeding tray for sowing and transplanting by a machine for sowing, sowing amount is adjustable, sowing precision is high, weight is light, labor intensity is little, and efficiency is high.

Description

technical field [0001] The utility model relates to a universal seeder for machine transplanting and throwing rice seedlings, which relates to the field of seeding machines. Background technique [0002] The leakage sowing technology invented by me (patent No. 2011205782577, 2010202328361) has been popularized and applied, but there are the following defects: because their meshes are distributed in a matrix, there are strip-like gaps in the sown seeds, and continuous empty insertion is prone to occur when machine transplanting ; The mesh of matrix distribution can not be used for the sowing of the seedling-throwing tray with the shape distribution of bowl holes. When the seeds are arranged by the device, the seeds that enter the mesh are easy to jump out, resulting in missed sowing. Leaky and sticky dual-purpose precision sowing device (patent number 2011205782577) has a sowing volume of only 50 grams, which is not suitable for large-scale sowing, and when sowing seeds with...

[0002]The leakage seeding technology invented by myself (patent No. 2011205782577, 2010202328361) has been popularized and applied, but there are the following defects: because their meshes are distributed in matrix, the sown There are strip-shaped gaps in the seedlings, and continuous empty insertion is easy to occur during machine transplanting; the meshes distributed in a matrix cannot be used for seeding in the throwing tray with the shape of the bowl holes. Their meshes are not in the shape of a bottleneck with a small top and a big bottom. When the seeder is shaken to arrange the seeds, the seeds that enter the mesh are easy to jump out, resulting in missed sowing.

Leaky and sticky dual-purpose precision sowing device (patent number 2011205782577) has a sowing volume of only 50 grams, which is not suitable for large-scale sowing, and when sowing seeds with thorns, the thorns of the seeds are easy to drill into the interlayer and get stuck, thus blocking the mesh. ; In addition, the setting of the key component "wire hoop" in the original leak-seeding technology needs to be further improved
