Description
Technical field
The invention belongs to a kind of agricultural machinery device of crop seeding, be specifically related to a kind of automatic dropping type seed sowing device.
Background technology
Existing seeding unit technology can be divided into three kinds: spoon formula seeding unit, rotating disc type seeding unit, air suction type seeding unit.Spoon formula seeding unit can well be realized the Precision Seeding function, but spoon casting and processing are difficult, and the poor reliability of ladling out seed; Rotating disc type seeding unit seed breakage rate height; The air suction type seeding unit is subjected to the rotating speed size variation to influence greatly the Precision Seeding weak effect.
Summary of the invention
Technical problem to be solved by this invention provides a kind of automatic dropping type seed sowing device, and this seeding unit is simple in structure, dependable performance, and the seed breakage rate is little, and Precision Seeding is effective.
Technical scheme of the present invention: a kind of automatic dropping type seed sowing device, it comprises the seeding unit seat, plant the dish mandrel, spacer, bearing gland, deposit kind of a dish, dividing plate, ladle out kind of a dish, grain cover, first screw, packing ring, second screw, the 3rd screw, the 4th screw, first nut, second nut, the bullet pad, key and bearing, left end is provided with two bearings on the kind dish mandrel, be provided with spacer between two bearings, bearing and spacer are arranged in the seeding unit seat, bearing gland is connected with the seeding unit seat by the 3rd screw, depositing kind of dish is connected with kind dish mandrel by key, dividing plate, ladling out kind of a dish is arranged on kind of the dish mandrel by first screw, packing ring, first nut connects, deposit kind of a dish, dividing plate, ladling out kind of dish connects by the 4th screw, second nut, the bullet pad is arranged on kind of the right-hand member of dish mandrel, and the seeding unit seat is connected by second screw with grain cover.
The line of the installing hole of seeding unit seat and kind dish mandrel center line angle of inclination are 25 °～35 °.
The present invention compared with prior art has following beneficial effect: the present invention is simple in structure, dependable performance, the seed breakage rate is little, the weight of dependence seed self falls into ladles out in kind of the dish slotted eye, forwarding certain position to falls into by deadweight again and deposits kind in the dish location notch hole, forward the bottom to and land, can realize the Precision Seeding seed, and cavitation does not have substantially.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
A kind of automatic dropping type seed sowing device, it comprises seeding unit seat 1, plant dish mandrel 2, spacer 3, bearing gland 4, deposit kind of a dish 5, dividing plate 6, ladle out kind of a dish 7, grain cover 8, first screw 9, packing ring 10, second screw 11, the 3rd screw 12, the 4th screw 13, first nut 14, second nut 15, bullet pad 16, key 17 and bearing 18, left end is provided with two bearings 18 on the kind dish mandrel 2, be provided with spacer 3 between two bearings 18, bearing 18 and spacer 3 are arranged in the seeding unit seat 1, bearing gland 4 is connected with seeding unit seat 1 by the 3rd screw 12, depositing kind of a dish 5 is connected with kind dish mandrel 2 by key 17, dividing plate 6, ladling out kind of a dish 7 is arranged on kind of the dish mandrel 2 by first screw 9, packing ring 10, first nut 14 connects, deposit kind of a dish 5, dividing plate 6, ladling out kind of dish 7 connects by the 4th screw 13, second nut 15, bullet pad 16 is arranged on kind of the right-hand member of dish mandrel 2, and seeding unit seat 1 is connected by second screw 11 with grain cover (8).
The line of the installing hole of seeding unit seat 1 and kind dish mandrel 2 center line angles of inclination are 30 °.
As shown in Figure 1, seed enters seeding unit from grain cover 8 top circular orifices, because seeding unit seat 1 tilts, seed falls into by deadweight and ladles out kind of the circular hole of dish 7, the degree of depth in each hole can only be held a seed, deposit kind of dish 5 and ladle out the rotation synchronously of kind of dish 7, on being rotated counterclockwise dividing plate 6 during the opening part of long lumbar hole, seed falls into by deadweight safety and deposits in kind of dish 5 locating slots, and can not be stuck in dividing plate 6 and deposit kind dish 5, ladle out and cause the seed fragmentation between kind of the dish 7, when continuing to rotate to seeding unit seat 1 lower ending opening place, seed lands realizes sowing.
