Description

The hand-held three-wheel seeder

The utility model relates to a kind of hand-held three-wheel seeder, belongs to agricultural machinery.

At present, the sower that China uses on kind ground in rural area, adopt Sledge type rack construction, the resistance of motion is very big during sowing, needs with the traction of two livestock, can only sow a ridge one time, and can not finish roll-in at random, and be unfavorable for soil moisture content, be unsuitable for the damage caused by a drought sowing and use, seeder bearings at both ends particularly, nearer from the ridge platform, very easily be involved in sand during work, cause bearing short service life, the machine of need often tearing open is repaired and is changed, incur loss through delay the sowing time, this machine need deliver with car when using, and gets on or off the bus and wants the several people to move, the coarse heaviness of complete machine, labour intensity is big; Occur a kind of Multifunction Precision Seeding machine that adopts tractor-drawn on the recent market,, but improved and planted the ground cost, increased peasant burden, be unsuitable for the self-employed farmer and use though it has liberated productivity to a certain extent.

The utility model provides a kind of hand-held three-wheel seeder at the problems referred to above, and it only draws with a livestock, can broadcast two ridges one time, and the sowing overall process is once finished in roll-in at random, improves sowing efficient, can resist spring drought again, improve soil moisture content, improve emergence rate, guarantee seeding quality.

Task of the present utility model is finished as follows: this hand-held three-wheel seeder, in frame front fixed drive axle, be equipped with driving wheel and driving wheel differential clutch pawl on the axle, and in this center fixed drive sprocket wheel, two seeders are fixed on the frame rear portion side by side, and the turning cylinder of two seeders united two into one make an axis, this centre position is provided with dog clutch and driven sprocket, tail wheel is connected in frame rear end by tail wheel bracket with bearing pin, the tail wheel bracket other end is hinged on the tail wheel crane, this tail wheel crane one end connects with tail-gear spindle, the other end and tail wheel lifter drawing bar are hinged, hand steered on be fixed with the pull bar limiting block, fix a tractive axle in tail wheel crane upper side, seeder axis clutch wedge is enclosed within on this tractive axle, pressure roller is connected in seeder by link rod and heightens on the bar, main ploughshare, the chemical fertilizer carrier pipe, pay ploughshare, seed transport tube, the fertile carrier pipe of mouth, banker is arranged in below the frame from front to back successively, frame front end fixed traction hook.

The utility model drives hinge wheel and drives minor sprocket owing to adopt front-wheel drive to advance, and seeder is started working, and through ditch dug with a plow, apply fertilizer to the subsoil, dibbling, execute a mouthful fertilizer, ridging, roll-in, disposablely finishes sowing work; In hand steered last sliding tie rod is left limiting block, tail wheel is raised, and the clutch wedge is by the tension of tail wheel crane side tractive axle simultaneously, and clutch disconnects, and seeder quits work; Pull back hand steered this moment, and under the effect of front driving wheel differential clutch pawl, one takes turns as you werely, and one takes turns stressed rotation, just rotatable 180 degree; The utility model adopts the pneumatic tyre three-wheel, the friction of motion resistance reduces, only can spur, adopt two seeders once to sow two ridges with a livestock, time saving and energy saving, improve sowing efficient, when not being engaged in agriculture, coming and going and to do the go-cart use in the way, above the seed farm implements are placed on, be very much convenient, be suitable for the self-employed farmer and use.

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

Fig. 1 is the utility model overall structure figure

With reference to accompanying drawing 1, be view more convenient description directly perceived, omitted a seeder among this figure, this hand-held three-wheel seeder, in the anterior fixed drive axle of frame [9] [10], be equipped with driving wheel [11] and driving wheel differential clutch pawl on the axle, and in this center fixed drive sprocket wheel [12], two seeders [1] are fixed on the frame rear portion side by side, and the turning cylinder of two seeders united two into one make an axis, this centre position is provided with dog clutch [13] and driven sprocket [14], tail wheel [15] is connected in frame rear end by tail wheel bracket [16] with bearing pin [17], the tail wheel bracket other end is hinged on the tail wheel crane [18], this tail wheel crane one end connects with tail-gear spindle, the other end and tail wheel lifter drawing bar [19] are hinged, be fixed with pull bar limiting block [21] on the hand steered handle [20], fix a tractive axle [22] in tail wheel crane [18] upper side, seeder axis clutch wedge [23] is enclosed within on this tractive axle, pressure roller [24] is connected in seeder by link rod [25] and heightens on the bar [26], main ploughshare [2], chemical fertilizer carrier pipe [3], pay ploughshare [4], seed transport tube [5], mouth fertile carrier pipe [6], banker [7] is arranged in below the frame from front to back successively, frame front end fixed traction hook [8].
