Description

Miniature paddy fields harrow with seats

The utility model relates to a kind of machines working in paddy field, particularly a kind of paddy field tractor-propelled harrow that uses with walking tractor matching.

Present southern paddy-field-working and walking tractor matching are used with the paddy field harrow of blade roll as workpiece, form by draw-gear, rake frame, blade roll, roller support etc., draw-gear is a rigid attachment with connecting of tractor, the forward position of roller support is rectangular with the rake frame, has only single-row blade roll.This head of raking the soil level is turned dumb, and plough-leaking phenomenon is arranged; The inclination angle of rake frame can not be regulated, and is difficult to adapt to the job requirements in different mud pin degree of depth plot; This rake does not have the seat, and the operator must operate in walking, and labour intensity is big; Return in the operation in field at straw, the grass of extension is arranged and twine careless phenomenon.

The purpose of this utility model is to design a kind of can the use with walking tractor matching, and field flexible operation, light, compact conformation are once ploughed the small-sized paddy field harrow of taking that rake can realize pressing effects such as grass, stubble-cleaning, hack, a slurry.

The small-sized paddy field harrow of taking of the present utility model is by the rake frame, drawing pull bar, roller support, bearing, connector, composition such as securing member and seat cushion, drawing pull bar and tractor adopt hinge to articulate, adopt hinge-coupled with the rake frame, have a hinge seat and an adjustable plate on the longitudinal axis position of rake frame, several adjustment holes are arranged on the adjustable plate, drawing pull bar is a stock, the one end has the hanging joint of a pin-and-hole perpendicular to the ground, the bent seat cushion that rises of the other end just is positioned on bent rising on end face, with rake on the frame hinge seat and the corresponding position of adjustment hole on a rocker bar bearing and a cross through hole are arranged respectively, this hole can be that circular hole also can be a groove shape through hole, and the pan that bearing pin passes on hinge seat and the rocker bar bearing is hinged on drawing pull bar on the rake frame.The pin-and-hole of hanging joint is articulated on the tractor, and the operation of raking the soil level is regulated tilling depth by adjustment hole.The forward position of roller support is 70 degree--the angle of 45 degree with the rake frame, hangs grass in the time of can avoiding operation.

Paddy field harrow of the present utility model has compact conformation, and flexible operation, light can be regulated tilling depth, can adapt to the characteristics such as job requirements in different mud pin degree of depth plot.Articulate with the hinge type of tractor, turn flexibly, can avoid edge of a field plough-leaking phenomenon, and facility are not yielding, and the seat is installed on the rake, and the operator can take operation, alleviated labour intensity greatly, to more solid paddy field, people's body weight can play effect of gain to facility, to softer field, but also walking operation of people, to indivedual pits, low-lying place, facility are under the situation of retardance, and the operator also can mention or push away one allows facility pass through smoothly.These facility return the field operation to magma field and straw excellent especially effect, cooperates grass pressing wheel still can disposablely finish under the situation of not shredding straw to press grass, stubble-cleaning, hack, rises and starch operation, can replace rotovator to carry out paddy-field-working.

In order fully to describe the small-sized paddy field harrow of taking of the present utility model, be illustrated for example below:

Accompanying drawing is a small-sized schematic diagram of taking paddy field harrow of the present utility model.

Rake frame 1 is rectangular, a hinge seat 2 is welded in its front end longitudinal axis position, an adjustable plate 3 is welded in the longitudinal axis position of rear end, adjustable plate 3 curves " Jiong " shape by angle steel, uprightly be welded on the rake frame, five adjustment holes are respectively arranged on the two sides, and being evenly distributed on bearing pin 7 respectively is the center of circle, is on the circumference of radius with its distance to adjustment hole.Drawing pull bar 4 is hollow steel pipes, one section pin pipe of one end welding, and mouth of pipe direction is perpendicular to the ground, becomes hanging joint 5, and the other end of drawing pull bar 4 is bent to be risen, and wooden seat cushion 9 is installed on the bent end face that rises.Drawing pull bar 4 with hinge seat 2 corresponding positions on the welding one hinged-support, bearing pin 7 drawing pull bar 4 be hinged on the rake frame on.Drawing pull bar 4 can be around bearing pin 7 motions, there is a cross through hole corresponding on the drawing pull bar 4 with adjustment hole, put the centre of drawing pull bar 4 in adjustable plate 3, bearing pin 8 is fixed on drawing pull bar 4 on the adjustable plate 3 by adjustment hole, put bearing pin 8 and can regulate the operation inclination angle of rake frame 1, thereby realize the tilling depth adjusting in different adjustment holes.Roller support 6 is fixed on the rake frame 1 by securing member, and its forward position is 60 degree with the angle of rake frame 1, and two row prismatic blade rolls are installed respectively on two groups of roller supports by bearing, and the rear end dress lastblock dashboard of rake frame 1 promptly becomes a small-sized paddy field harrow of taking.
