Background technology
The patent No. is that the utility model patent of 200920225772.X discloses a kind of steering device used for rice transplanter, comprise the first Connection Block 1 and the second Connection Block 7, the first Connection Block 1 is connected by back shaft 14 with the second Connection Block 7, back shaft 14 is provided with bevel gear, the quantity of described bevel gear is one or two, and two bevel gears form double bevel wheel.
In said structure, adopt two bevel gears to form the mode of double bevel wheel, the switched in opposite of line shaft 13 and the first intermediate propeller shaft 16, need on rice transplanter, install the power input requirements that commutator could meet rice transplanter additional, need four bevel gears to cooperatively interact could be by transmission of power to rear power output shaft simultaneously, complex structure.
While adopting a Bevel Gear Transmission, the 5th bevel gear 27 is arranged on the below of the first bevel gear 20 and the 4th bevel gear 17, and mesh with the first bevel gear 20 and the 4th bevel gear 17 simultaneously, the switched in opposite of line shaft 13 and the first intermediate propeller shaft 16, without installing commutator additional, structure is simpler, but because the 5th bevel gear 27 is arranged on the below of the first bevel gear 20 and the 4th bevel gear 17, rice transplanter long-term work is in moist earth environment, after the long-term use of sleeve 15, the bearing at its two ends is easy to wearing and tearing, after bearing wear due to the reason of sleeve 15 self gravitations, the 5th bevel gear 27 can be along with sleeve 15 moves down, cause the 5th bevel gear 27 not mesh with the first bevel gear 20 or the 4th bevel gear 17, can only again change bearing or gear, increased maintenance cost, reduced service life simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, and a kind of structure letter is provided
Single, can reduce costs, transmission of power is steadily reliable, long service life, steering angle is large, turns to the rice transplanter steering wheel without dead angle.
For addressing the above problem, the utility model is by the following technical solutions: a kind of rice transplanter steering wheel, comprise holder, the swivel mount being rotatably connected in holder, between holder and swivel mount, by connecting axle, be rotationally connected, on described connecting axle, be rotatably connected to sleeve, on sleeve, be fixedly connected with the first bevel gear, on described the first bevel gear, be engaged with the second bevel gear and third hand tap gear, described the first bevel gear is arranged on the top of the second bevel gear and third hand tap gear.Adopt after the bearing wear of said structure in sleeve, sleeve, because self gravitation declines, drives the first bevel gear to decline, and guarantees that the first bevel gear also remains engagement with the second bevel gear and third hand tap gear all the time, has improved the service life of steering wheel.
Below further improvement of the utility model:
On described swivel mount, be fixedly connected with semicircular gear ring, position near gear ring on holder is rotatably connected to duplicate gear, one of them gear of duplicate gear and gear ring engagement, on another gear, be engaged with tooth sector, on tooth sector, be fixedly connected with steering spindle, in steering spindle, be fixedly connected with steering wheel.Adopt technique scheme, by semicircle gear ring and duplicate gear, mesh, gear ring driven rotary frame rotates, and then drives rice transplanter to turn to, and turns to without dead angle, and left and right turn angle can reach 90 °.
Further improve:
On described holder, be fixedly connected with bearing block, power input shaft is fixedly connected with the second bevel gear through bearing block.It is more steady that the setting of bearing block can make power input shaft rotate.
Further improve:
On described holder, be rotatably connected to power input shaft, the second bevel gear is fixed on power input shaft, on described third hand tap gear, is fixedly connected with power take-off, and power take-off is passed with the power shaft of rice transplanter and is connected by swivel mount.
The utility model adopts technique scheme, and power just can pass to power take-off through three bevel gears after being exported by gear-box, does not need to install additional commutator simultaneously, and transmission of power is steadily reliable, makes structure simpler, has reduced cost simultaneously; Described the first bevel gear is arranged on the top of the second bevel gear and third hand tap gear, even the first bevel gear and the second bevel gear and third hand tap gear also remain engagement in the situation of the bearing wear in sleeve, has improved service life; The mode that adopts the moving swivel mount of semi-circular teeth astragal to rotate can facilitate turning to of rice transplanter, turns to without dead angle, and steering angle can reach 90 °; It is more steady that the setting of bearing block can make power input shaft rotate.
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
