Abstract

The present invention discloses a differential and rotating type ordered seedling throwing device. An outer roller, a middle roller and an inner roller are fixed by flanges into an integral body. A plurality of coaxial holes are uniformly distributed on the rollers. Push rods which are provided with springs penetrate through roller holes. A row of cams which are orderly arranged according to phases are fixed on cam shafts which are corresponding to each cycle of push rods in the inner roller and are parallel to a supporting shaft of the rollers. A drive chainwheel which is sheathed on the supporting shaft and gears which are fixedly connected with the drive chainwheel and are arranged in the rollers transfer movement power to gears which are fixedly arranged on the cam shafts to drive the cam shafts to rotate. The rollers and the push rods are driven by a chainwheel which is sheathed on a coupling band between the drive chainwheel and the gears drive and is connected with the rollers. The push rods which contact the cams are pushed by the profiles of lift range sections of the cams to push out rice bowl seedlings in bowls of seedling throwing disks in conical holes on the wall of the outer roller, and the rice bowl seedlings fall into a field along a seedling guiding pipe. The rotating speed ratio of the cams and the rollers is equal to the number of a circle of holes on walls of the rollers to orderly push out each row of the bowl seedlings which fall into the same range of the field on the bowl disk to guarantee an equal planting distance.

Description

Differential and rotating type ordering rice seedlings thransplanting device

Technical field

The present invention relates to transplanting machine, especially relate to a kind of differential and rotating type ordering rice seedlings thransplanting device.

Background technology

At present, the motor-driven throwing transplanting machine of the paddy rice of selling on the market divides unordered rice transplanting and ordered seedling throwing at home.Unordered rice transplanting operation is simple, but the uniformity of rice shoot in the field is difficult to assurance, and particular needs the peasant again with manually putting again, brings a lot of inconvenience also for later stage field management and results, and owing to problems such as ventilation cause disease.Ordered seedling throwing can overcome the disadvantage of unordered rice transplanting, but realizes relatively difficulty, will guarantee that particularly spacing in the rows equates to have very big difficulty; At present domestic also do not have product to come into the market, and external product is too complicated.

Summary of the invention

The objective of the invention is: a kind of differential and rotating type ordering rice seedlings thransplanting device is provided, makes ejecting of rice shoot have uniformity.Can guarantee that line-spacing equates, can guarantee that again spacing in the rows equates, and simple in structure, reliable operation.

In order to achieve the above object, the technical solution used in the present invention is: its outer cylinder, intermediate calender rolls and interior cylinder are fixed as one by left and right flanges, are supported on the left and right a set of cups, between left and right a set of cups and central shaft rolling bearing are housed; All be uniform-distribution with some coaxial apertures on three layers of cylinder, push rod from radial direction cross be distributed on outside the hole of cylinder, intermediate calender rolls and interior cylinder, on the push rod between interior cylinder and intermediate calender rolls, spring is housed, one end of spring withstands on push rod one end and the shaft shoulder that intermediate calender rolls contacts, and the other end of spring withstands on the press strip that is fixed on intermediate calender rolls.Be enclosed within the drive sprocket on the central shaft, gear that is loaded on cylinder inside by being connected and the gears engaged that is packed on the camshaft with it, sprocket wheel on the another set of coupling band between the gear of drive sprocket and cylinder inside is connected with three layers of cylinder, correspondingly with every circle push rod in interior cylinder with on the camshaft of the central axes of cylinder, fixing N the rotating cam that a row arranges successively by phase place, the rotating ratio of cam and cylinder equals on the cylinder wall hole count on the circumference, the interior accurate rice pot seedling of rice transplanting dish alms bowl bowl that the lift section of rotating cam, the push rod that profile promotes to be in contact with it will be loaded in the outer cylinder cinclides ejects.

A described N cam is 16 and is divided into 2 groups, is symmetrically arranged vertically on camshaft by phase difference, and the phase difference between every group of cam calculates by test to be determined.Described camshaft is a splined shaft.

The beneficial effect that invention has is: three layers of cylinder are by the chain wheel drive uniform rotation, push rod rotates with three layers of cylinder, cam then by sprocket wheel by gear drive, turn over the angle of adjacent two push rods of same circle when cylinder, camshaft just in time turns over a circle, the push rod that cam on the camshaft promotes the same delegation that is in contact with it successively will be loaded on the rice transplanting dish in the outer cylinder cinclides and eject with the accurate rice pot seedling in the alms bowl bowl of delegation, the pot seedling free-falling, fall into Tanaka along seedling guide canal, finish the ordered seedling throwing operation.The rotating ratio of cam and cylinder equals on the cylinder wall hole count on the circumference, makes every row on the alms bowl dish fall into the field and is ejected successively with the pot seedling of delegation, guarantees that spacing in the rows equates.
