Summary of the invention
The purpose of the invention is exactly the problem that exists to above-mentioned prior art, combine to intersect before and after the capable adjacent rice shoot of the adjacent seedling of paddy rice the agronomy demand of dislocation rice transplanting; Design provides about a kind of rice transplanter seedling case of new construction the intermittently traversing helical axis of use, reaches line-spacing rice transplanters such as can adapting to tradition and accomplishes and intersect the operation use of dislocation rice transplanting before and after the capable adjacent rice shoot of adjacent seedling; More can adapt to wide-and narrow-row rice transplanter (elongating narrow row spacing in the rows in the ranks) and accomplish the use of the capable adjacent rice shoot front and back intersection dislocation rice transplanting of adjacent seedling, promote the new agricultural process technology in mechanized, to apply, reach the purpose that improves rice crop output.
The purpose of the invention is achieved in that two seedling pawl operating angles that rice transplanter adjacent two is gone transplant arms differ 180 ° and are equipped with; When the seedling pawl of adjacent two row will a seedling pawl seedling taking in operation process like this, the seedling pawl of adjacent lines is just in rice transplanting; Replace laddering seedling taking and rice transplanting, realized the agriculture requirement of the adjacent rice shoot front and back intersection dislocation rice transplanting that the adjacent seedling of paddy rice is capable.
Under the prerequisite of the equipped new intention of this kind of the invention transplant arm; Though realized the adjacent rice shoot front and back intersection dislocated type rice transplanting that adjacent seedling is capable; But the transplant arm seedling pawl seedling taking position that under the condition of the helical axis groove transmission seedling case transverse moving left and right of traditional rice transplanter, will produce delegation is normally correct; And the transplant arm seedling pawl of adjacent lines is because the seedling taking angle differs 180 °; So adjacent lines seedling taking position can continue the at the uniform velocity traversing seedling taking dislocation that causes on the seedling blanket along with the seedling case, causes inclined to one side seedling taking, few seedling taking and leakage seedling taking.
The invention has designed about rice transplanter seedling case the intermittently traversing helical axis of using to above problem, on screw shaft surface, is symmetrical set opposite traversing, the right traversing spiral grooves in a seedling case left side that is used for of the hand of spiral and stops the traversing groove of seedling case be used for vertical with axial line that is connected at interval with spiral grooves.Described helical axis groove can drive in the groove on the sliding sleeve stylus pin in helical axis rotation, and to drive the seedling case traversing or stop traversing; Driving seedling case moved, does not drive when in perpendicular to the groove of axial line, moving the seedling case and moves (also being the tram of transplant arm seedling pawl seedling taking at this moment) when stylus pin moved in spiral grooves; So just stopped having won in traversing time enough and made adjacent two row transplant arm seedling pawls successively each has once intermittently accomplished the seedling taking operation of tram on the stall position at identical seedling case, thereby realized that the capable adjacent rice shoot of adjacent seedling intersects dislocated type rice transplanting purpose at the seedling case.Described spiral grooves and vertical central line trenches form closed type reciprocation cycle groove circuit realizing that a seedling case batch (-type) left side is traversing end to end with the right traversing stroke route of batch (-type).
The invention is novel in design; Simple and reasonable; Drive reliablely, it is wide to be suitable for type, highly versatile; Satisfy the operation needs that wait line-spacing rice transplanter and wide-and narrow-row rice transplanter to accomplish the capable adjacent rice seedling front and back intersection dislocation rice transplanting of adjacent seedling, promoted applying of advanced agronomic technique.
