Abstract

The utility model discloses a shallow-water direct seeding machine for rice. The utility model mainly comprises a small traveling machine body driven by dragging, a trailing bar, a gear transmission mechanism and a sowing mechanism; the trailing bar is connected with the machine body; the gear transmission mechanism is arranged on the trailing bar; the sowing mechanism is composed of a seed box, a seed discharge wheel and a planter plate. The utility model is characterized in that the utility model is suitable for realizing the mechanized shallow-water direct seeding for the seeds which are a layer of oxygen releasing agent, and the traditional rice producing mode in the past, raising the seedling and transplanting the seedling, is changed. The utility model has the advantages of time saving and labor saving, the production cost is reduced, and the output is guaranteed. The utility model is suitable for exploiting the land with the medium or low output in large area, and is particularly suitable for large households with the farm machinery in the paddy field producing district and for the large households with the paddy field.

Description

Shallow-water direct seeding machine of rice

The utility model relates to a kind of proportion of crop planting machinery, particularly a kind of paddy rice shallow water seed-sowing machine.

At present, the domestic paddy rice mode of production overwhelming majority be still adopt grow seedlings, the conventional approach of rice transplanting produces, and is time-consuming, require great effort though this way is beneficial to the high yield of paddy rice, causes its production cost greatly to improve.Also have the many less areas of a few peoples to adopt manual way of spreading seed (comprising the seed that spreads through parcel one deck oxygen discharge agent) to produce, though this way is easy, output is lower.

In view of the foregoing, the purpose of this utility model provides and a kind ofly both can reduce production costs, and can reach rice transplanting output again, realizes paddy rice shallow water seed-sowing machine efficient, high yield.

The purpose of this utility model is achieved in that it comprises that the small tractor that is made of engine, gearbox, walking assembly drives traveling machine body and the planker that links to each other with this body and is located at gear drive, sowing mechanism on the planker, and the power take-off of gearbox links to each other with the power input shaft of gear drive through a power transmission shaft in the small tractor driving traveling machine body; Sowing mechanism is by kind of a case, seed plate and be located between kind of case lower port and the seed plate upper port and seed wheel that its surface has kind of a spoon constitutes, and the wheel shaft of seed wheel links to each other with the output shaft of gear drive by flexible axle.During work,, will plant the seed (this seed has wrapped up one deck oxygen discharge agent) that case flows down by the kind spoon on the seed wheel and cast in the ground through seed plate by small tractor gearbox power take-off driven gear transmission mechanism and sowing mechanism work.

In order to prevent that seed wheel when work from causing sowing mechanism to damage because of catching phenomenon occurring, also above-mentioned seed shaft can be made fixed axis, driven gear is housed on it, this gear links to each other with seed wheel by a driving spring sheet, the below of driven gear is provided with a driving gear that is meshed with it, links to each other with the power take-off of gear drive by flexible axle with the wheel shaft that this driving gear is connected.When catching phenomenon appearred in seed wheel, driving spring sheet and seed wheel can break away from automatically, can play the overload clutch effect.

The utility model has the advantages that: change growing seedlings of adopting of present Rice Production, rice transplanting traditional approach into the mechanization shallow water live mode of production, therefore save time, laborsaving, greatly reduce the Rice Production cost.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the gear drive schematic diagram.

Fig. 3 is the sowing mechanism schematic diagram.

Fig. 4 is the right side view of Fig. 3.

Provide embodiment as can be known by accompanying drawing, this paddy rice shallow water seed-sowing machine comprises that mainly the small tractor that is made of engine 1, gearbox 2, walking assembly 4 drives traveling machine body and the planker 7 that links to each other with this body and is located at gear drive, sowing mechanism on the planker.Gear drive is made of casing 9 and the power input shaft 17, driving gear 18, driven gear 19, jackshaft 20, change-speed gearing 21, power output gear 22, the power take-off 23 that are located in the casing, power input shaft 17 links to each other with power transmission shaft 6 through universal joint 8, and the other end of power transmission shaft 6 links to each other with the power take-off (not marking among the figure) of gearbox 2 through universal joint 3; Sowing mechanism is made of kind of case 11, seed wheel 29, seed shaft 26, driving spring sheet 27, driven gear 30, driving gear 31, seed plate 13, the wheel shaft 33 of driving gear 31 links to each other with power take-off 23 in the gear drive by flexible axle 10, seed plate 13 links to each other with bracing frame 34 on the planker 7, planting spoon 28 is connected on the seed wheel 29, the 10 degree angles that tilt, base plate 24 tops of kind of case 11, the bottom turn forward 40 the degree angles, make the paddy rice kind be in the optimal flow state, well fill kind of a condition to guarantee that kind of a spoon 28 has.Sequence number 32 is respectively scriber and the branch kind plate that is located in the seed plate 13 among sequence number 5 among Fig. 1 and Fig. 4.The rear portion of planker 7 is provided with plough 14, dashboard 15, multiple clod 16.Seed falls into from seed plate 13 in the kind ditch of being opened by plough 14, then the seed that will fall into kind of ditch by multiple clod 16 with mud topped on, can finish the sowing process.
