Embodiment Construction
[0012] Take the three-arm rotary box as an example.
[0013] Three planting arm rotary boxes, which at least include a box body 1, a drive shaft 10, a main gear 2, three idlers 8, three idler shafts 3, three driven gears 5, three output shafts 7 and Three buffer cams 4. The box body 1 is in the radial shape of three arms, each arm is evenly distributed around the drive shaft 10, the drive shaft 10 is fixed at the center of the box body 1, the main gear 2 is set on the drive shaft 10, and is fixed on the chain through the adapter 9. The drive shaft sleeve 11 on the transmission box casing 12 is connected. Each arm of the box body 1 is provided with a transmission branch composed of an idler 8, an idler shaft 3, a driven gear 5, an output shaft 7 and a buffer cam 4. The wheel shaft 3 is fixed on the box body 1, the output shaft 7 is erected on the box body 1 through the bearing 6, the idler gear 8 is set on the idler shaft 3, the axial direction is fixed, the radial direction ...

The invention provides a rotating box with multiple transplanter arms, which relates to an agricultural machine. The rotating box at least comprise a box body, a driving shaft, a driving gear, idle wheels, idle wheel shafts, a driven gear and an output shaft, wherein the driving shaft and the idle wheel shafts are fixed on the box body; the output shafts are hinged on the box body; the driving gear is sleeved on the driving shaft and is connected with a driving shaft sleeve fixed on the shell of a chain wheel box; the idle wheels are sleeved on the idle wheel shafts; the driven gears are fixed on the output shafts; the driving gear, the idle wheels and the driven gears are noncircular gears and are normally meshed. The rotating box is characterized in that: the box body has three or more than three support arms arranged in a radial form and evenly distributed around the driving shaft; and a drive branch consisting of an idle wheel, an idle wheel shaft, a driven gear and an output shaft is arranged in each support arm. The rotating box ensures high transplanting efficiency, reduces the linear speed at which a single tansplanter arm takes seedling and ensures high survival rate of the seedlings.
Description
technical field [0001] The invention relates to an agricultural machine, in particular to a rotary box of a planting mechanism for a rice transplanter. Background technique [0002] With the increasing popularization and innovation of agricultural machinery, the machine rice transplanting equipment widely used has been gradually replaced by the walking type by the riding type. The ride-on rice transplanter is a high-speed rice transplanter. The transplanting mechanism of the rice transplanter adopts a double-planting arm rotary box, that is, two transmission branches are separated from the drive shaft of the rotary box to drive the two planting arms to work, and the rotary box When the drive shaft rotates once, each of the two transplanting arms transplants once, and the total number of transplants per minute can reach 500 times. The advantage of the rotary double-arm transplanting mechanism is high operating efficiency, but the disadvantage is that the drive shaft of the r...
