Description
Technical field
The utility model relates to a kind of farm machinery, the transplanting mechanism revolution case that particularly a kind of rice transplanter is used.
Background technology
Along with popularizing day by day and the innovation replacement of farm machinery, the machine transplanting of rice seedling facility of being promoted the use of by large tracts of land are replaced by sitting type gradually by hand-held.The sitting type rice transplanter is high-speed transplanter, the transplanting mechanism of this rice transplanter adopts two transplanting arm revolution casees, promptly tell two transmission branch roads from revolution case driving shaft, drive two transplanting arm work, revolution case driving shaft turns around, two each rice transplantings of transplanting arm once, per minute rice transplanting total degree can reach 500 times.The advantage of the two arm-type transplanting of the transplanting mechanisms of revolution is operating efficiency height, and shortcoming is that the seedling taking linear velocity of transplanting arm is too high, easily causes and hinders the seedling phenomenon, has influenced the survival rate of planting the back rice shoot because the transplanting mechanism revolution case drive shaft speed of high-speed transplanter is too fast.Therefore how when improving the rice transplanter operating efficiency, the seedling taking linear velocity of transplanting arm is lowered, to guarantee the survival rate of rice shoot, become technical barrier anxious to be solved.
Summary of the invention
The purpose of this utility model is to provide a kind of can guarantee higher rice transplanting operating efficiency, can guarantee the rotating box with multiple transplanter arms of higher rice shoot survival rate again.
Technical solution of the present utility model is: rotating box with multiple transplanter arms, which comprises at least casing, driving shaft, master gear, idle pulley, idler shaft, driven gear and output shaft, driving shaft, idler shaft is fixed on the casing, output shaft is located on the casing by bearing bracket stand, master gear is enclosed within on the driving shaft, and be connected with propeller shaft sleeve on being fixed on the chain-wheel box shell by connector, idle pulley is enclosed within on the idler shaft, driven gear is fixed on the output shaft, master gear, idle pulley and driven gear are non-circular gear and normal engagement, it is characterized in that: casing is above radial of three support arms or three support arms, each support arm is uniform around the driving shaft five equilibrium, is provided with one in each support arm by idle pulley, idler shaft, the transmission branch road that driven gear and output shaft are formed.
The drive path of described rotating box with multiple transplanter arms is: driving shaft transmission case body, idle pulley are followed casing and are rotated around master gear, idle pulley transfer driven gear, driven gear transmission output shaft.
The output shaft of described rotating box with multiple transplanter arms also is fixed with a buffering cam, and the buffering action of cam is that the transplanting arm seedling taking and the turning power of planting in the process realize are cushioned.
Because casing of the present utility model is above radial of three support arms or three support arms, each support arm is uniform around the driving shaft five equilibrium, be provided with a transmission branch road of forming by idle pulley, idler shaft, driven gear and output shaft in each support arm, top at each casing support arm is equipped with output shaft, therefore by the utility model transplanting arm more than 3 or 3 can be installed, driving shaft rotates a circle, and each transplanting arm work once.When the rice transplanting total degree of rice transplanter remains unchanged, the operating frequency of transplanting arm reduced, the seedling taking linear velocity of transplanting arm decreases, so the utility model has reduced seedling-damaging ratio to greatest extent, guarantee the probability that survives of rice shoot, improved the operation quality of transplanting mechanism.
Description of drawings
Fig. 1 is the utility model embodiment schematic diagram.
Fig. 2 shows the transmission schematic diagram for the utility model embodiment A-A cuts open.
Among the figure: 1, casing, 2, master gear, 3, idler shaft, 4, the buffering cam, 5, driven gear, 6, bearing, 7, output shaft, 8, idle pulley, 9, connector, 10, driving shaft, 11, propeller shaft sleeve, 12, the chain case casing.
Below in conjunction with accompanying drawing the utility model is elaborated.
Embodiment
With three transplanting arms revolution case is example.
Three transplanting arms revolutions case which comprises at least a casing 1, driving shaft 10, master gear 2, three idle pulleys 8, three idler shafts 3, three driven gears 5, three output shafts 7 and three buffering cams 4.It is radial that casing 1 is three support arms, and each support arm is uniform around driving shaft 10 five equilibriums, and driving shaft 10 is fixed on casing 1 center, and master gear 2 is enclosed within on the driving shaft 10, and be connected with propeller shaft sleeve 11 on being fixed on chain case casing 12 by connector 9.Be provided with one in casing 1 each support arm by an idle pulley 8, idler shaft 3, driven gear 5, an output shaft 7 and the transmission branch road that buffering cam 4 is formed, idler shaft 3 is fixed on the casing 1, output shaft 7 is erected on the casing 1 by bearing 6, idle pulley 8 is enclosed within on the idler shaft 3, axial restraint, radially unfixing, driven gear 5 and buffering cam 4 are fixed on the output shaft 7, and master gear 2, idle pulley 8 and driven gear 5 are non-circular gear and normal engagement.The effect of buffering cam 4 is that the transplanting arm seedling taking and the turning power of planting in the process realize are cushioned.
In the utility model, power is provided by the chain drive case, and driving shaft 10 passes to power on the revolution box body 1 then, drives casing 1 and at the uniform velocity rotates.Because the master gear 2 in the casing 1 is fixedlyed connected by propeller shaft sleeve 11 with chain drive box body 12, so master gear 2 does not rotate; And will rotate along with the rotation of driving shaft 10 with the idle pulley 8 of master gear 2 engagement and with the driven gear 5 of idle pulley 8 engagements, drive output shaft 7 and the conventional transplanting arm rotation that is installed on the output shaft 7 again, the rotation direction of transplanting arm is identical with the rotation direction of revolution case.Again because master gear 2, idle pulley 8 and and the driven gear 5 of idle pulley 8 engagements be non-circular gear, when being embodiment with three revolution of arm casees, the non-circular gear modulus all is made as 2, the number of teeth all is made as 22, the rotating speed right and wrong of driven gear 5 at the uniform velocity but be cyclically-varying, the revolution case turns around, and driven gear 5 is finished the variation in a week.Because driven gear 5 drives the transplanting arm rotation, so transplanting arm also is into cyclically-varying with respect to the rotary speed of revolution case, so just guaranteed that the movement locus of seedling pawl becomes the class ellipse on the transplanting arm,, guaranteed the performance requirement of seedling taking and rice transplanting like " the extra large drop of water " shape.
