Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1～4, in the embodiment of the present invention, a kind of 8 cun of line-spacing step transplanters that adapt to the production requirement of double cropping rice agronomy, comprise engine assembly 1, transmission assembly 2, assembly of drive gear 3, seedling box assembly 4, support assembly 5, kickboard assembly 6 and land wheel drive assembly 7, the both sides of described support assembly 5 are provided with land wheel drive assembly 7, the input of land wheel drive assembly 7 connects the output of transmission assembly 2, the input of described transmission assembly 2 is by belt transmission connecting engine assembly 1, thereby realize engine assembly 1 for power, drive the support assembly 5 follow-up transplanting work that advances, and the line-spacing of support assembly 5 is 264mm, described land wheel drive assembly 7 connects the kickboard assembly 6 of bottom by connecting rod, the overall length of described kickboard assembly 6 is 735mm, and the width that kickboard assembly 6 is latter a section is 155 mm, the width that makes kickboard assembly 6 relatively and the kickboard narrowed width of prior art, thereby prevent that in rice transplanter walking process, kickboard both sides generations " surge " cause rice shoot lodging,
Described transmission assembly 2 connects seedling box assembly 4 by assembly of drive gear 3, thereby the work that ensures seedling box assembly 4 can well-regulatedly complete, described seedling box assembly 4 is made up of for main body seedling case 42, seedling case 42 connects transplanting arm 41, thereby make from seedling case 42 rice shoot out be planted in paddy field through transplanting arm 41, described transplanting arm 41 is positioned at road wheel 71 rears so that protection rice shoot; The seedling case 42 of the single file that described seedling box assembly 4 is grown by several 1064mm forms.
Seedling box assembly is mainly transferred the parts such as arm, seedling handover slide bar by transplanting power input shaft, transplanting clutch cam, input sprocket, seedling case displaced spirals axle, guide, seedling and is formed.Its Main Function is that the power being passed over by gear-box is passed to respectively to seedlings sending mechanism and transplanting arm, realizes horizontal stroke, vertical seedlings sending and rice transplanting action.Due to after the line-spacing of the support assembly 5 of rice transplanter diminishes accordingly, the helical axis stroke in transplanting portion casing also diminishes with regard to corresponding, and therefore, the corresponding shortening of casing, to ensure the installation site of installing positions of bearings and transplanting arm of helical axis.
Kickboard is the weight in order to bear rice transplanter, keeps rice transplanter not sink.After line-spacing changes, the width of a section will interfere with transplanting arm after middle kickboard, and can produce " gushing mud ", buries the phenomenon of rice transplanting seedling.Therefore, the size of a section after middle kickboard must be redesigned and improves.The change of size need to be considered two factors: the first, and the variation of kickboard size should keep bearing area substantially constant; The second, " gushing mud " that in rice transplanter traveling process, kickboard produces can not be caused and bury rice transplanting seedling.
The situation of " gushing mud " and occur based on above-mentioned factor and field reality, according to line-spacing, by the reduced width of a section after middle kickboard to 155 mm, than 9 cun of machines narrow 50 mm; Length is increased to 735 mm, has lengthened 105 mm than 9 cun of machines.The size constancy of one section before middle kickboard.After improvement, the overall bearing area of middle kickboard reduces by 152.25 cm than 9 cun of machines
2.But because many parts such as transplanting portion casing, seedling case and seedling case guide rail, slide bar diminish, shorten, 8 cun of machine overall weights alleviate, and still can keep ground pressure substantially constant.
Helical axis is the vital part of controlling the steadily reliable transverse shifting of seedling case.Its requirement on machining accuracy is high, not only requires often to get seedling one time, and seedling case displacement is consistent, to ensure to plant evenly, and requires often to complete once laterally to move after case, can be neat arrange blanket appearance seedling one and take together with bed soil.Therefore, the pitch of helical axis and total kilometres are major parameters of helical axis.
Former 9 cun of machines often complete rice transplanting action, and transverse shifting seedling case amount minimum is 10.8 mm.At every dish seeding quantity 100-110 g(seed rice that shows money or valuables one carries unintentionally), longitudinally seedling taking amount 8 mm, minimum seedling taking area is 0.864 cm
2time, can ensure each seedling taking 1-2 young plant.This minimum seedling taking amount substantially can meet plant seedling few one season hybrid rice plant requirement.
Under the master-plan framework of transmission of power parameter constant, ensure minimum seedling taking area, just require the helical axis pitch of 8 cun of machines consistent with former 9 cun of machines.
Total kilometres are relevant with structure with horizontal seedling taking number of times and single file seedling case width again.Total principle is:
(1), in the width range of seedling pin (seedling pawl), by the seedling taking of whole number of times, row's seedling can be taken;
(2) area of each seedling taking must equal or less times greater than former 9 cun of machines, to ensure to plant quality;
(3) for the rice shoot that ensures each single file seedling case does not interfere with one another, the partition muscle width between each single file seedling case maintains the size constancy of former 9 cun of machines.
According to calculating, the size of 8 cun of line-spacings is decided to be 8 × 33 mm=264 mm, partition muscle between seedling case is wide is 20 mm, seedling setting gate width 20 mm, shake while considering transplanting mechanism work, stays 1.5 mm gaps on one side between seedling pin and seedling setting gate, therefore, the total kilometres that seedling case moves are also that the total kilometres of helical axis are: 264-20-20-(2 × 1.5)=221 mm.
As for parameters such as the diameter of helical axis, spiral fluted width, groove depths, and helical axis material and processing technology, still consistent with the parameter of 9 cun of machines, to increase the versatility of parts.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the present invention.Any Reference numeral in claim should be considered as limiting related claim.
