Abstract
The invention discloses a transmission mechanism of a seeder, which comprises an input transmission shaft, a first sprocket wheel, an output transmission shaft, a second sprocket wheel and a chain. The first sprocket wheel is arranged on the input transmission shaft; the second sprocket wheel is arranged on the output transmission shaft; and the chain is arranged on the first and the second sprocket wheels. The transmission mechanism of the seeder is characterized in that: the input transmission shaft is connected with the wheel hub of a tractor rotating wheel; the output transmission shaft is connected with the main shaft gearbox of the seeder; and the chain is provided with a floating tension device. In the transmission mechanism of the seeder of the invention, the input transmission shaft is connected with the transmission mechanism which enables the tractor to go forward, and the transmission chain is provided with the floating tension device which is used for tensioning the loosened chain at the traction section to realize the tension control for the chain, so the synchronization of the input and the output transmission shafts is ensured, the phenomena of miss-seeding and non-uniform seeding density are avoided, and the seeding quality of the farmland is increased.
Description
Technical field
The present invention relates to a kind ofly, belong to agricultural seeder machinery manufacturing field with the supporting transmission mechanism of seeder of large and middle tractor.
Background technology
China's agricultural seeder machinery all is above the rotovator of the rear of tractor suspension seeder to be set with the mode of large and medium-sized tractor at present, and its power delivery mode has several: a kind of is to stretch out a spindle nose by the rotovator gear-box to be delivered on the seeder main shaft by sprocket wheel, chain; Another kind is to be delivered on the seeder main shaft by sprocket wheel, chain from an end spindle nose of rotary ploughing cutter shaft; The third is to place a suppression roller at the rotovator rear, by driving the seeder main axis rotation by sprocket wheel, chain on the spindle nose of suppression roller.The problem that preceding dual mode exists is because the pace of tractor and the rotation speed change of rotovator gear-box (or cutter shaft) are nonsynchronous, when advancing speed gearshift or when adding the macro-axis door and quickening to advance, gear-box and cutter shaft rotary tillage speed is synchronous change not, planter the cave is appearred apart from becoming big like this, it is thinning that seed density is appearred in drilling machine, influences seeding accuracy.Though and the third has overcome last two kinds of nonsynchronous shortcomings, slightly see it is synchronous, but because situation is changeable in the farmland operation, straw-returning is promoted in particularly current farmland, straw, straw usually are wrapped on the suppression roller, make the suppression roller block, can not rotate continuously, or on stalk, skid and do not rotate, maybe ought run into being uneven, the suppression roller is blocked rotating speed and can changes or not change, and the uneven phenomenon of broadcast leakage and thickness of sowing occurs and still exists, so all there are some drawbacks in various degree in above-mentioned three kinds of methods, influence the farmland seeding quality.
Summary of the invention
For overcoming at present and the supporting existing technical problem of transmission mechanism of seeder of large and middle tractor, the invention provides a kind of with the supporting transmission mechanism of seeder of large and middle tractor, this transmission mechanism not only makes the planting with sowing machine case planting seed speed can be mutually harmonious with the large and middle tractor pace, and simple and reliable for structure.
The technical scheme that technical solution problem of the present invention is adopted is: a kind of transmission mechanism of seeder, comprise input shaft, be arranged on first sprocket wheel, take-off (propeller) shaft on the input shaft, be arranged on second sprocket wheel on the take-off (propeller) shaft and be arranged on chain on first sprocket wheel, second sprocket wheel, it is characterized in that: described input shaft is connected on the tractor moving runner wheel hub, described take-off (propeller) shaft is connected on the sower shaft transmission, also is provided with a unsteady tensioning apparatus on described chain.
Described unsteady tensioning apparatus comprises case, described case one end and input shaft are rotationally connected, be provided with at least one pressure roller, at least one every roller and at least one carrying roller at the other end of case, described pressure roller is arranged on the traction section of described chain, described carrying roller is arranged under the loopback section of described chain, between the described traction section and loopback section that is arranged on described chain every roller.
Be provided with jockey between described input shaft and tractor moving runner wheel hub, this jockey is flange, axle, axle sleeve or spline.
Transmission mechanism of seeder of the present invention, input shaft is connected on the transmission mechanism that tractor advances, unsteady tensioning apparatus is set on driving chain, when the downward kiss the earth of planting with sowing machine device is sowed, air line distance between seeder and the large and middle tractor is elongated, a traction section chain tension is gone up pressure roller one and shroud body one end is upwards held up by contacted with it, makes shroud body with the rotation of floating of a traction section chain tension; Otherwise, when seeder makes progress built on stilts, air line distance between itself and the large and middle tractor shortens, and a traction section chain fluffs sagging, and shroud body relies on deadweight one end to press down the rotation of floating, press down by last pressure roller one, with the traction section chain tension that fluffs, realize tensioning control, thereby assurance input shaft and take-off (propeller) shaft are synchronous to chain, avoid the generation of broadcast leakage and thickness of sowing non-uniform phenomenon, improved the farmland seeding quality.
The invention has the beneficial effects as follows:
1) seeder sowing transmission mechanism directly is connected with the large and middle tractor transmission mechanism that advances, and can guarantee that the mechanical pace of seeder planting seed speed and power traction coordinates mutually, has greatly improved the seeding quality of sower;
2) transmission mechanism is simple in structure, reliable, practical, and is energy-saving and cost-reducing, reduces production costs;
3) the unsteady both securable chain of case can protect chain and sprocket wheel one again.
