Description

A kind of control method of width spacing in the rows rice transplanter

Technical field

The present invention relates to a kind of rice transplanter, especially relate to the control method of a kind of rice transplanter.

Background technology

The implanting mechanism of common rice transplanter such as Publication No. The implanting mechanism of a kind of rice transplanter disclosed in the Chinese patent of CN2805334, it includes chain gear transmission case, the revolution case being symmetrically mounted on the chain gear transmission case left and right sides and transplanting arm, it is provided with planetary gears, the position that transplanting arm is arranged on planet wheel spindle, turns round between casing and adpting flange in wherein said revolution case.Along with the development of modern agriculture, the foster planting technology of Oryza sativa L. is also constantly improving.Research shows, in the middle of Rice Cropping, its line space uses the mode illumination most beneficial for Oryza sativa L. of a wide narrow interval plantation, ventilation, alleviates pest and disease damage, improves yield.In order to develop this technology, people also design various rice transplanter, as the Chinese patent of Publication No. CN101790917 discloses a kind of universal joint-driven inclined wide-and-narrow separating-planting mechanism of rice transplanter.The identical transmission case of structure and planting arm it is respectively mounted in sprocket shaft both sides;Sprocket shaft becomes an inclination angle by universal joint output shaft with sprocket shaft, universal joint output shaft end is affixed with planet carrier, in planet carrier, central gear passes through bearings on universal joint output shaft, and by flange, adjust pad and the flange on universal joint end transmission case body and fix and be connected, central gear is connected with respective planetary gear respectively through idler gear, fixes the planet wheel spindle being connected with planetary gear and connects respective planting arm respectively.This invention makes the seedling pin on the planting arm that planetary gear drives move in the clinoplain of relative sprocket shaft, then seedling pin is after seedling taking, owing to the inclination of planet carrier produces the lateral movement relative to direction of advance, making rice shoot a little relative seedling taking position of burying move to left or move to right, the wide-and narrow-row making rice transplanting position form agriculture requirement under seedling fetching hole is equally spaced premise does not waits line-spacing distribution.But, sometimes, owing to ploughing, it is more suitable for reaching to improve illumination and the effect of ventilation by width spacing in the rows, and such scheme cannot complete.

Summary of the invention

The present invention mainly solves the technical problem that cannot realize width spacing in the rows rice transplanting existing for prior art, it is provided that one can realize width spacing in the rows rice transplanting easily, reaches to improve illumination and ventilation, it is achieved the control method of the width spacing in the rows rice transplanter of volume increase.

The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals: the control method of a kind of width spacing in the rows rice transplanter, this rice transplanter includes walking mechanism, drive mechanism, implanting mechanism, implanting mechanism includes some transversely arranged transplanting casees, each transplanting case is respectively equipped with the most each revolution case, each revolution case be respectively arranged at two ends with a transplanting arm, it is characterized in that described implanting mechanism is provided with the primary input axle of a horizontally set, this primary input axle power intake with described transplanting case respectively is connected, described primary input axle is connected with described drive mechanism, if described revolution case rotation one week is a period of motion T of drive mechanism, its control method is as follows:

One period of motion T is divided into again working cycle T1 and gap periods T2, in working cycle T1, two transplanting arms of revolution case are continuously finished the most complete seedling taking, rice transplanting process, subsequently into gap periods T2, drive mechanism often operates and adjusts a velocity of rotation after a working cycle T1, slows down or stops operating, after gap periods terminates in gap periods, drive mechanism recovers again rated speed so that primary input axle is speed alternating movement in a period of motion T.

In working cycle T1, drive mechanism drives revolution case to move with rated speed, and this implanting mechanism completes twice transplanting action within a working cycle altogether, subsequently into gap periods, in gap periods, turns round case low speed or stops operating.Due to rice transplanter in normal operating conditions, at the uniform velocity walking, the control method of this rice transplanter can realize the wide narrow mutant of rice transplanting spacing one away from transplanting, reaches to improve illumination and ventilation, it is achieved the purpose of volume increase.

As preferably, the angle of revolution between the revolution case on adjacent two described transplanting casees with 90 degree is poor, two revolution case synchronised on same transplanting case.The program makes to stagger between the transplanting position of the transplanting arms on two revolution casees on the transplanting position of the transplanting arm on previous transplanting case two revolution casees and later transplanting case, with first, as a example by second and the 3rd transplanting case, the seedling that the transplanting arm turning round case on the seedling inserted of transplanting arm of the later revolution case on first transplanting case and second transplanting case is inserted is not correspond to, and it is corresponding with the seedling that the transplanting arm of the revolution case on the 3rd transplanting case is inserted, therefore the spacing of the transplanting arm that the program makes actual line-spacing be the later revolution transplanting arm of case on first transplanting case and the previous revolution case on the 3rd transplanting case, in the case of not losing seedling density, reached to improve the effect of rice shoot line-spacing, improve its logical light draught capacity further.

As preferably, described drive mechanism is hydraulic system, and this hydraulic system includes the hydraulic motor being connected with described primary input axle;The hydraulic pump being connected with oil cylinder and corresponding fluid pressure line, described hydraulic pump control circuit and a control unit are connected, after starting work, control unit is at the pump speed oil of a critical point hydraulic pump of adjustment of each T1, T2, so that hydraulic motor realizes speed in cycle T and replaces.

As preferably, described drive mechanism is a motor, and the control circuit of this motor is connected with a control unit, after starting work, the critical point of control unit each T1, T2 adjusts the rotating speed of a motor, so that this motor realizes speed in cycle T and replaces.

Bringing of the present invention provides the benefit that, solve the technical problem that cannot realize width spacing in the rows rice transplanting existing for prior art, achieve one and can realize width spacing in the rows rice transplanting easily, reach to improve illumination and ventilation, it is achieved the control method of the width spacing in the rows rice transplanter of volume increase.
