Background technology
Traditional rice cropping generally all to adopt etc. line-spacing, etc. the transplanting method of spacing in the rows, but the problem of sunshade will inevitably be there is between this transplanting method plant and plant, and uneven to utilizing of the nutrient in earth, thus cause very large waste.Current wide-and narrow-row rice transplanting method is widely used, and it is a kind of high-yielding rice cultivation technique that narrow row distance and wide line-spacing interval are cultivated.This planting type can cave number on guarantor unit's area reasonable, have again plant population distribution rationally, ventilation and penetrating light performance is good, photosynthetic rate advantages of higher, and therefore unit yield is higher, is one of planting type of often selecting of high yield trial.Meanwhile, because ventilation and penetrating light strengthens, humidity between rice strain is reduced, the harm of disease worm can be alleviated to a certain extent, finally reach the object that high yield increases income.Current people have devised multiple wide-and narrow-row rice transplanter, to adapt to the requirement on above-mentioned agronomy, but, due to the requirement of various geographical conditions, as the azimuth tendency of land, the factors such as illumination condition, we need to adopt the method for width spacing in the rows to obtain corresponding ventilation and penetrating light condition, so just need a kind of width spacing in the rows rice transplanter, namely inserted rice shoot is that width is arranged alternately at the direction of travel of rice transplanter.As publication number is: the Chinese patent of CN104663086A discloses a kind of implanting mechanism of novel width spacing in the rows rice transplanter, comprise some transversely arranged transplanting casees, each transplanting case is respectively equipped with each revolution case around, the two ends of each revolution case are respectively equipped with a transplanting arm, described implanting mechanism is provided with the primary input axle of a horizontally set, this primary input axle is connected with each transplanting case, and be connected with power intake by a non-speed change rotating box at the uniform velocity exported, this change gearbox comprises the change gear pair of one or several changeable work, each change gear pair is made up of driving gear and driven gear, each driving gear is all connected with power intake by corresponding transmission mechanism, each driven gear is connected with described primary input axle by corresponding transmission mechanism.This technical scheme achieves the object of width spacing in the rows rice transplanting, but due to its complex structure, clutch end is the process of variable speed, so the impact that its mechanism bears can be larger, these factors comprehensive, make the fault rate of the implanting mechanism of this rice transplanter high, the stability of operation is also lower.
In addition, if on the basis of the width change on line-spacing, the width change of rice transplanting spacing in the rows is added, just can realize two-dimentional width rice transplanting, the Edge advantages of crop obtains larger embodiment, and the ventilation of crop, logical light, the ability reducing insect pest can be greatly improved.But existing rice transplanting machinery all cannot complete the two-dimentional width rice transplanting that line-spacing width and spacing in the rows width realize simultaneously.
Summary of the invention
The present invention mainly solves complex structure existing for prior art, fault rate is high, the technical problems such as operational stability is poor, provides a kind of structure simple, failure rate is low, the even rotating speed two dimension width rice transplanter of good stability.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of even rotating speed width spacing in the rows rice transplanter, comprise vehicle frame, seedling platform and implanting mechanism, implanting mechanism is provided with revolution case, the two ends of revolution case are respectively equipped with transplanting arm, each transplanting arm is respectively equipped with a transplanting claw, described Miao Tai is connected with seedling platform driving mechanism, this seedling platform driving mechanism is provided with a helical axis, this helical axis is connected with power end, described seedling platform is provided with screw thread guide block, the leading end of this screw thread guide block adapts in the thread groove of described helical axis, the thread groove of described helical axis is by growing apart from guide groove and microspur guide groove is spaced is connected in series, a long distance guide groove is a helical pitch, a microspur guide groove is half helical pitch, the leading end of described screw thread guide block moves to the process of the other end from a long one end apart from guide groove, described transplanting claw is by twice seedling taking position, and obtain rice shoot, the leading end of described screw thread guide block moves to the process of the other end from one end of a microspur guide groove, the transplanting claw of implanting mechanism is by a seedling taking position, but can not rice shoot be obtained.Described implanting mechanism comprises some transplanting casees of single setting, the upper end of transplanting case is connected with driving mechanism, lower end is provided with revolution case, the two ends of revolution case are provided with transplanting arm, each transplanting arm is provided with transplanting claw, and described revolution case is one group with three, and in group, revolution case is equidistantly arranged, the spacing of the adjacent revolution case between two adjacent groups is 1.5-2 times of group interior revolution case spacing, and often group revolution case carries seedling plate corresponding to described in one.When using the present invention to carry out rice transplanting, the rotation drive of helical axis is connected seedling platform with screw thread guide block and moves, due to this helical axis by by long apart from guide groove with microspur guide groove is spaced is connected in series, so mobile inevitable one piece one of seedling platform hockets slowly, in this motion process, in the uniform rotation process of revolution case, former and later two revolution casees of revolution case are even, constant duration by getting seedling position, but because seedling platform translational speed speed replaces, when screw thread guide block corresponds to long guide groove, namely when seedling platform moves fast, transplanting claw passes twice through seedling taking position, and get rice shoot, when screw thread guide block corresponds to micro-guide groove, namely when seedling platform moves at a slow speed, transplanting claw is for once by seedling taking position, and due in this process, the displacement of seedling platform is too short, transplanting claw can not get rice shoot.After transplanting claw can not get rice shoot, this transplanting claw will arrive into once empty rice transplanting, then proceeds twice and inserts in fact.Rear end, this rice transplanter was formed, and the process of the alternately operating that once sky is inserted, twice is inserted in fact forms the rice transplanting method of width spacing in the rows.
Existing wide-and narrow-row rice transplanter generally has two kinds, one is that seedling fetching hole is evenly arranged, wide-and narrow-row rice transplanting is realized by the lateral displacement of revolution case in rotation process, this rice transplanter mainly carries out transforming arranging to adapt on existing common seedling transplanter, its main feature is the seedling platform that can adopt existing common seedling transplanter, another kind is that seedling fetching hole is arranged to width spacing, and the setting of revolution case is corresponding with seedling fetching hole.These two kinds of rice transplanters all achieve a wide narrow interval variation of seedling planting row pitch.And the present invention is one group of revolution case by three, and the spacing of three revolution casees is less, and the spacing between group and group is that the 1.5-2 wide-and narrow-row realizing the wide row of two narrow rows one that arranges doubly of the spacing of revolution case in group is arranged.
The present invention in use, the rotation of revolution case one week is a period of motion of system, this motion week its in, the transmission of revolution case and change gear pair exports and all completes a speed alternately, under the drive of change gear pair, revolution case to complete after twice rice transplanting low speed fast or suspends certain hour, enter the next period of motion again, due in the process, the overall uniform rotation of rice transplanter, so, it achieve front two strain rice shoot close together, second strain rice shoot and the 3rd strain distant, 4th strain and the 3rd spacing in the rows are from close to again ... the transplanting effect of width spacing in the rows.
