Description

Technical Field

[0001] The utility model relates to a portable single seeder. Background Art

[0002] At present, a Chinese patent with the authorization announcement number CN2764117Y discloses a portable automatic seeding and fertilizing device, which has a seed and fertilizer box, a seed and fertilizer channel, and a duckbill for entering the soil. There is a transmission body in the outer jacket. The transmission body is connected to the controller, and the controller is composed of a rack and a rocker brake. The rack meshes with the teeth of the cylindrical adjustment part. The up and down movement of the rack causes the adjustment part to rotate forward and backward. The adjustment part passes through the seed and fertilizer channel and a seed and fertilizer placement groove is provided on the cylindrical surface. The placement groove fits with the seed and fertilizer outlet of the box. A duckbill control mechanism composed of an elastic rocker arm, a rocker arm shaft, a pulley, a pulley shaft, a controller and a pull rod is provided between the seed and fertilizer boxes. When the pulley on the elastic rocker arm is at the uppermost end of the arc-shaped wall of the rocker arm brake, the seed and fertilizer duckbill is opened to the maximum, and when it is at any point on the slope of the rocker arm brake, the seed and fertilizer duckbill is closed. The utility model loaded with seeds and fertilizers is placed on the ridge of the field, and is repeatedly pressed down and lifted up according to the planting spacing requirements, so that the seeds and fertilizers can be automatically sown and applied in the ridges of the field.

[0003] This portable automatic seeding and fertilizing device reduces labor intensity. The seeds are placed in a seed box. During the sowing process, the number of seeds will gradually decrease, but farmers cannot see the approximate amount of seeds remaining in the seed box, so it is inconvenient to use.
