Abstract

The utility model discloses a seeder, including a seed box and seed feeding mechanism; the seed feeding mechanism includes more than three uniformly distributed seed feeding boxes arranged under the seed box, a seed feeding pipe connected under each seed feeding box, a spindle passing through all of seed feeding boxes and a rotating member driving the spindle to rotate; each seed feeding box is internally provided with a rotary seed feeding plate fixedly connected with the spindle; a separator with an opening is arranged above each seed feeding box; the rotary seed feeding plate has more than six seed receiving grooves which are concentrically uniformly distributed; the width of each seed receiving groove of the rotary seed feeding plate is adaptive to that of the opening of the separator; and the space between the maximum excircle of the rotary seed feeding plate and the separator is 1-3mm. In the utility model, the seeder employing such structure can guarantee crops to be uniformly and reasonably distributed in fields and achieve accurate seeding.

Description

A kind of sower

Technical field

The utility model relates to agricultural mechanical field, relates in particular to a kind of sower.

Background technology

Existing sower comprises seed-box, feed mechanism, grain tube, road wheel, plough, covering device and hanger bracket, feed mechanism comprises the sheave of tanker below and blocks wheel, the sheave surface has groove, sheave rotates in being full of the feed up of seed during work, seed also is being with and is being moved, and discharges through seed cup gate.Such structure is difficult to reach the requirement of accurate sowing.

The utility model content

Technical problem to be solved in the utility model is: a kind of sower is provided, and this kind sowing function guarantees accurately sowing.

Solve this technical problem, the technical solution of the utility model is: a kind of sower, comprise seed-box and feed mechanism, described feed mechanism comprises and is positioned at seed-box below uniform seeds discharging box more than three, be connected in the discharging tube of each seeds discharging box below, pass a mandrel of whole seeds discharging boxes and drive the rotatable parts that mandrel rotates, have the rotation seed plate affixed in described each seeds discharging box with mandrel, the top of each seeds discharging box has the dividing plate that has opening, described rotation seed plate has the Sheng kind groove more than six uniform on the concentric circles, the width that each of rotating seed plate contained kind of groove adapts with the A/F of dividing plate, the maximum cylindrical of rotation seed plate and dividing plate be spaced apart 1～3 millimeter.

The quantity of described seeds discharging box is six.

Described rotation seed plate has eight uniform on concentric circles Sheng kind of grooves.

A kind of sower of the utility model adopts such structure, the movement means mandrel of feed mechanism rotates, rotation seed plate in each seeds discharging box rotates thereupon, seed in the seed-box falls within the Sheng kind groove that rotates seed plate from the opening of dividing plate, each capacity of containing kind of groove is identical, thereby the amount of seed metering that guarantees each whereabouts is consistent, and has guaranteed accurate sowing.

Below in conjunction with accompanying drawing a kind of sower of the utility model is done explanation in further detail;

Fig. 1 is the structural representation of a kind of sower of the utility model;

Fig. 2 is the structure for amplifying schematic diagram of feed mechanism shown in Figure 1;

Fig. 3 is a seeds discharging box cross section enlarged diagram shown in Figure 2;

In Fig. 1, Fig. 2, Fig. 3,1, seed-box; 2, feed mechanism; 3, grain tube; 4, road wheel; 5, plough; 6, covering device; 7, hanger bracket; 8, rotatable parts; 9, mandrel; 10, seeds discharging box; 11, rotate seed plate; 12, dividing plate.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3, sower comprises seed-box 1, feed mechanism 2, grain tube 3, road wheel 4, plough 5, covering device 6 and hanger bracket 7, feed mechanism 2 comprises and is positioned at six the uniform seeds discharging boxes 10 in seed-box 1 below, be connected in the grain tube 3 of each seeds discharging box 10 below, pass a mandrel 9 of whole seeds discharging boxes and drive the rotatable parts 8 that mandrel 9 rotates, have the rotation seed plate 11 affixed in described each seeds discharging box 10 with mandrel 9, the top of each seeds discharging box 10 has the dividing plate 12 that has opening, described rotation seed plate 11 has eight uniform on concentric circles Sheng kind of grooves, the width that each of rotating seed plate 11 contained kind of groove adapts with the A/F of dividing plate 12, the maximum cylindrical of rotation seed plate 11 and dividing plate 12 be spaced apart 1～3 millimeter.During use, the rotatable parts 8 of feed mechanism drive mandrel 9 and rotate, rotation seed plate 11 in each seeds discharging box 10 rotates thereupon, seed in the seed-box 1 falls within the Sheng kind groove that rotates seed plate 11 from the opening of dividing plate 12, each capacity of containing kind of groove is identical, thereby the amount of seed metering that guarantees each whereabouts is consistent, and can guarantee that crop is reasonable being evenly distributed of field, reaches accurate sowing.

Claims (3)

1. sower, comprise seed-box (1) and feed mechanism (2), it is characterized in that: described feed mechanism (2) comprises and is positioned at seed-box (1) below uniform seeds discharging box (10) more than three, be connected in the grain tube (3) of each seeds discharging box (10) below, pass a mandrel (9) of whole seeds discharging boxes and drive the rotatable parts (8) that mandrel (9) rotates, have in described each seeds discharging box (10) and the affixed rotation seed plate (11) of mandrel (9), the top of each seeds discharging box (10) has the dividing plate (12) that has opening, described rotation seed plate (11) has the Sheng kind groove more than six uniform on the concentric circles, the width that each of rotating seed plate (11) contained kind of groove adapts with the A/F of dividing plate (12), the maximum cylindrical of rotation seed plate (11) and dividing plate (12) be spaced apart 1～3 millimeter.

2. a kind of sower according to claim 1 is characterized in that: the quantity of described seeds discharging box (10) is six.

3. a kind of sower according to claim 1 is characterized in that: described rotation seed plate (11) has eight uniform on concentric circles Sheng kind of grooves.
