Abstract

The utility model discloses a double-line precise wheat seeder which consists of a rack, a land wheel, a seed box, a seeding mechanism, a seed pipe, an opener, a roller and a chain gearing. The utility model is characterized in that the number of the seed holes on the seeding mechanism is twice as many as that of the opener; each seed hole is connected with one seed pipe, and every two seed pipes are connected with one shovel-type opener to form two sowing holes with one on the right and one on the left; between the two sowing holes is a V-typed baffle which gives the two sowing holes an interval of three to five centimeters. The utility model, by means of the double-line precise planting, realizes a dense planting by joint work of two single-line precise planting. The output of the double-line precise planting is fifteen percent more than that of the single-line precise planting or single-line dense planting under the same management, and the maximum output is up to six hundred and fifty kilograms per Chinese acre.

Description

Wheat two-wire Precision Seeding machine

Technical field

The utility model belongs to agricultural machinery, especially seeding machinery.

Background technology

Its structure of domestic and international existing wheat seeder is identical substantially, all is made up of frame, land wheel, seed-box, seeding unit, grain tube, plough, press wheel, chain gearing.Plough recited above is installed on the crossbeam, the mountain area is with an installation 1-2 plough of manpower pulling, the Plain is the installation of power more than 5 even the plough more than 10 with the tractor, and each plough is only evenly broadcast delegation's seed, is commonly called as " single line sower ".This " single line sower " if seeding quantity is big, then can cause the seeding density on the single line big, influences the ontogeny of wheat and forms small ear; If the amount of broadcasting is little, then can cause the less than normal and mu spike number deficiency of colony, even Precision Seeding (referring to about the every mu of amount of sowing 5Kg) still influences wheat yield.

Summary of the invention

The contradiction of Precision Seeding and dense planting designed a grow wheat two-wire Precision Seeding machine when the purpose of this utility model was the sowing of solution wheat single line.

Main structure of the present utility model is made up of frame, land wheel, seed-box, seeding unit, grain tube, plough, press wheel, chain gearing.It is characterized in that the feed outlet number on the seeding unit is the twice of plough number, a grain tube is respectively arranged on each feed outlet; Per two grain tubes are connected in the shovel formula plough simultaneously, two mouths of sowing about the inboard formation of plough, sowing for two separates with " V " type baffle plate between the mouth, two mouthful center distance 3-5cm that sow.

When sower is worked, sow the seed that two single lines are arranged in each plough simultaneously, i.e. " two-wire Precision Seeding ".Utilize the mode of " two-wire Precision Seeding ", go up at every " single line " and realize Precision Seeding, reach dense planting jointly by two " single lines ".Wheat is gone up at " single line " and is grown stalwartness because of Precision Seeding, and wheat population is basic seedling abundance because of " two-wire " makes, even wheat ontogeny stalwartness has been given full play to the advantage that reasonable colony achieves higher output again.Under identical cultivation management condition, this two-wire Precision Seeding mode is increased production more than 15% than single line Precision Seeding and the thick broadcast mode of single line, and the high-yield field per mu yield can reach more than the 650kg.

Description of drawings

Fig. 1 is a wheat two-wire Precision Seeding machine structural representation, and Fig. 2 is the enlarged drawing of I portion plough left view among Fig. 1, and Fig. 3 is the vertical view of Fig. 2 plough, and Fig. 4 is the B-B cutaway view of Fig. 3 plough.

Among the figure: 1-frame, 2-support, 3-regulating wheel, 4-chain, the 5-feed outlet, 6-precision seeder, 7-rotating shaft, 8-seed-box, 9-power transmission shaft, 10-be by movable sprocket, 11-handrail, 12-clutch handle, the 13-copying spring, 14-press wheel, 15-plough, 16-seed level adjuster, the 17-clutch, 18-land axle, 19-land wheel, 20-crossbeam, 21-grain tube, 22-division board, the 23-mouth of sowing.

Embodiment

Two-wire Precision Seeding machine with three ploughs is an example below, and embodiment is described.

As shown in Figure 1 and Figure 2: on frame 1, be fixed with seed-box 8.Land wheel 19 is installed on the support 2 of frame 1 front end by land axle 18, side by side wheel shaft 18 is as power take-off, by chain 4, regulating wheel 3, power is reached in the rotating shaft 7 of precision seeder 6 by movable sprocket 10, power transmission shaft 9, feed outlet on the seeding unit 6 is six, and each feed outlet picks out a flexible pipe.Flexible pipe inserts in the grain tube 21, and grain tube 21 is that internal diameter is the plain cast iron pipe of 20mm.Two grain tubes 21 weld together the leg that constitutes plough 15 side by side, and are fixed on the crossbeam 20, and the spacing b=20-30cm between two legs, the end opening of grain tube 21 are the mouth 23 of sowing, and its end welds together with plough 15.Seed level adjuster 16 usefulness bolts are connected crossbeam 20 and grain tube 21 and plough 15 on the frame 1.Controlled clutch handle 12 can make clutch 17 work, realizes the switching of power, prevents to waste when sower from turning or inoperative is walked seed.Press wheel 14 is fixed in frame 1 rear respectively with handrail 11, and respectively there is a press wheel 14 back of each

plough

15, and 11 on press wheel 14 and handrail are connected with copying spring 13 simultaneously.

Plough shape of the present utility model as shown in Figure 3, Figure 4, it is to be welded with division board 22 in triangle trench digging 15, the cross section of division board 22 is reverse V-shaped, dehiscing to locate the vertical face of both wings is arc line type, outer wide value a=3-5cm, it can determine the width of two-wire seeding, also can effectively prevent to mix mutually from the seed that two grain tubes 21 fall, they are fallen into respectively in the kind ditch of division board 22 both sides, realize " two-wire " sowing of a ditch two row; Its camber line structure can prevent effectively that weeds obstruction kind of the ditch from influencing sowing depth simultaneously.

Claims

1, a grow wheat two-wire Precision Seeding machine, it is made up of frame, land wheel, seed-box, seeding unit, grain tube, plough, press wheel, chain gearing, it is characterized in that, feed outlet number on the described seeding unit is the twice of plough number, a grain tube is respectively arranged on each feed outlet, per two grain tubes are connected in the shovel formula plough simultaneously, two mouths of sowing about the inboard formation of plough, sowing for two separates with " V " type baffle plate between the mouth, two mouthful center distance 3-5cm that sow.
