Abstract

The utility model discloses a velocity differentia lever type sequential rice seedling thrown device. The outer, intermediate and inner rollers are fixed into a whole via flange. Several coaxial holes are evenly distributed on the roller. The mandril runs through the holes of the roller. A retracing spring is set on the mandril. At the opposite of the mandril on each circle of the inner roller are arranged sequential cams. Between the cylinder and inner roller, one array levers are fixed and covered on the right and left rest brackets and the supporting shaft which parallels main shaft. Bulges are both on the top of one end of the lever which is far from the supporting shaft and on the bottom of one end which is near the supporting shaft. The driving sprocket fixed on the main shaft drives the cam fixed on the roller. The other driving sprocket drives three levels roller and mandril. The lever is rest. When the cam touching the bulges at the bottom of the lever, cam push the lever swings around the supporting shaft. The top bulge pushes the mandril spring and ejects the rice seedling from the bowl of the thrown tray and the seedling drops to the fields through the seedling guiding tunnel. Then the rice seedling thrown operation is finished.

Description

A kind of differential level type ordering rice seedlings throwing device

Technical field

The utility model relates to transplanting machine, especially relates to a kind of differential level type ordering rice seedlings throwing 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 purpose of this utility model is: a kind of differential level type ordering rice seedlings throwing device is provided, makes ejecting of rice shoot have uniformity.Can guarantee that line-spacing equates, can guarantee that again spacing in the rows is even, and simple in structure, reliable operation.

In order to achieve the above object, the technical solution adopted in the utility model is: its outer cylinder, intermediate calender rolls and interior cylinder are fixed as one by flange, one end is supported on first adapter sleeve, the other end is fixed with the hinge wheel that is supported on second adapter sleeve, push rod from radial direction cross be distributed on outside cylinder, in intermediate calender rolls and the interior holes of drum, radial and axially on three layers of cylinder all be uniform-distribution with some coaxial apertures, on the push rod between interior cylinder and intermediate calender rolls, return spring is housed, one end of spring withstands on push rod one end and the shaft shoulder that interior cylinder contacts, and the other end of spring withstands on the press strip that is fixed in intermediate calender rolls.With fixing N the cam that a row arranges successively by phase place on the corresponding cylinder in interior cylinder of every circle push rod, between cylinder and interior cylinder, be equipped with parallel with main shaft, be supported on back shaft and gear shaft on the stationary bracket of two ends, be equipped with on back shaft that a row can rotate around it, N the lever corresponding with cam; Lever is provided with projection away from a side of the close push rod of back shaft one end, at the opposite side near back shaft one end projection is arranged also; Its movable end leans against gear shaft during the lever free state, during work, rotating cam touch lever near back shaft one end projection, promote lever around its back shaft swing, make projection away from back shaft one end promote push rod the accurate rice pot seedling in the seedling dish alms bowl bowl in the outer holes of drum ejected.

The number N of described cam and lever is 16, is divided into 2 groups along the main shaft symmetric arrangement; The rotating ratio of cam and three layers of cylinder equals on the cylinder wall hole count on the circumference.

The beneficial effect that the utlity model has is: during operation, drive sprocket on the main shaft drives the cam that is fixed on the cylinder and rotates, another drive sprocket drives three layers of cylinder, push rod and seedling dish and rotates in the same way with cam together, the rotating speed of cam and cylinder is different, rotating ratio equals the hole count of a circumference on the cylinder wall, cam ejects the accurate rice pot seedling in the rice transplanting dish alms bowl bowl in the outer cylinder cinclides by the lever pushing push rod, and pot seedling falls into Tanaka along leading the seedling pipe, finishes the ordered seedling throwing operation.This differential lever formula rice seedlings transplanter utilizes the differential gearing of cam and cylinder, and the amplification of leverage, has improved speed and rise that push rod ejects pot seedling greatly, has guaranteed the uniformity that same row's pot seedling is ejected and the uniformity of spacing in the rows.
