Description

Technical field

[0001] The utility model relates to sowing equipment, in particular to a sowing machine for granular seeds. [Background Technology]

[0002] Manual sowing is labor-intensive and inefficient, and the seed drills currently on the market are generally developed for large-scale operations. Therefore, there is an urgent need to develop agricultural machinery for sowing operations on medium and small areas of land to meet the mechanization needs of small-scale sowing operations of farmers' families. [Utility Model Content]

[0003] In order to achieve the above object, the technical solution of the utility model is as follows:

[0004] A small-sized seed drill comprises a transmission mechanism, a seeding mechanism, a traveling mechanism, a reversing mechanism, a furrow opener, a soil coverer and a frame for installing and fixing the various mechanisms of the seed drill.

[0005] The transmission mechanism comprises a motor (2), a worm gear reversing reducer (3), a four-branch gear sprocket set (10), and a traction rod (11). The motor (2) is mounted on a lower motor mounting plate of a frame (1). The motor output shaft is connected to a four-branch gear sprocket set (10) and a two-branch gear sprocket set (9). The two-branch gear sprocket set (9) is connected to another two-branch gear sprocket set mounted on a drive wheel (7) shaft via a chain, thereby driving the seeder forward and driving the furrow opener (5) and the soil coverer (6) to complete the furrowing and soil covering functions. At the same time, the motor output shaft is connected to the four-branch gear sprocket set (10) and another two-branch gear sprocket set (9) fixed on the seeder rotating shaft (8), which are connected via a chain to form a chain drive two, providing a power source for the seeder. The battery (17) and the motor are arranged in parallel on the mounting plate of the frame (1) to supply power to the seeder.

[0006] The frame is divided into two layers, the upper and lower layers, which are used to install and support various mechanisms of the seed drill. The entire frame is fixed on the traveling mechanism of the seed drill.

[0007] The walking mechanism comprises a driving wheel (7), a rotating shaft (8), a reversing wheel (19) and an axle assembly.

[0008] The sowing mechanism is composed of a seed box (4), a valve plate (13), a seed buffer disk (12), a seed guide tube (14) and a vertical shaft. The upper and lower disks of the seed buffer disk are radially evenly distributed with through holes for seeds to pass through. The sowing mechanism is connected to the worm gear reversing reducer (3) and the rotating shaft (8) through the vertical shaft. The output shaft of the worm gear reversing reducer (3) is connected to the seed disk, which drives the seed disk to rotate one circle. The through hole and the seed guide tube are connected once, and the seeds are discharged once.

[0009] The furrow opener (5) and the soil coverer (6) are fixed at the front section of the lower layer of the frame, and the soil coverer is fixed at the rear end of the lower layer of the frame. When installing, the furrow opener, the seeding port of the seeder, and the soil coverer are ensured to be in a line consistent with the movement direction of the seeder. When the seeder moves, the plowshare of the furrow opener loosens the soil in front and opens a furrow (seed hole), and the seeds fall into the furrow along the seed guide pipe port, and the eight-shaped wheel of the soil coverer at the back covers the seeds with soil.

[0010] The reversing mechanism is connected to the reversing wheel (19) by a traction rod (11) through a U-shaped fork structure (20). The upper cross bar of the traction rod (11) can be used to conveniently reverse the direction of the seeder and change rows for sowing.

[0011] Compared with the existing seeder, the utility model has the following effects:

[0012] During sowing, the motor is started, the manual toggle valve plate (13) is opened, the outer gate at the bottom of the seed box (4) is opened, and the seeds are adjusted by the gate and fall into the seed buffer tray (12). The space left by the seed buffer tray (12) and the protective shell will further buffer and control the seeds. The multiple elastic scrapers in the protective shell will once again ensure that the number of seeds entering the seed discharge port is controlled and effectively prevent the seeds from clogging the seed discharge port.
