Description

Multi-functional rod cutting machine

The utility model relates to agricultural equipment, and especially the felling harvester with the more sturdy pesticide meridian crop of bars such as corn, jowar, soybean, cotton, sugarcane, ramie stalk has the pass.

Domestic and international existing corn, sorghum category grain header are large-scale harvesting machinery, it only is adapted to the corn of the large-scale smooth contained kind in farm, the harvesting of sorghum category, it not only can not bring into play its advantage and for the little field of sowing area or for the harvesting of this class pesticide meridian crop of non-flat-bottomed land, seem powerless toward contact, come harvesting corn sorghum category crop so can only rely on backward manual felling mode these regional peasants, not only labour intensity is big for this, and harvesting speed is slow; In addition, for the pesticide meridian crop of sugarcane, ramie and so on, in China special felling harvesting machinery is not arranged as yet at present, peasants also can only lean on manual felling harvesting, and this is that labour intensity is big, felling harvesting speed is slow equally.

The purpose of this utility model is to provide a kind of multi-functional rod cutting machine to the public, and its structure is light, and felling harvesting speed is fast, can be widely used in the felling harvesting of the more sturdy pesticide meridian crop of bar stalks such as corn, jowar, soybean, cotton, sugarcane, ramie.

The utility model is mainly by control stick, rotating cutter, accumulator, electromotor, power switch and power line are formed, control stick is single pole or wooden ladder shape double link, at the control stick front end rotating cutter is housed, rotating cutter is discoid saw blade cutter of dark tooth or cross chopper, at the control stick front end, electromotor is equipped with at follower head or middle any position, rotating cutter is with the rotating shaft of electromotor or directly be connected transmission, or connect transmission indirectly by driving-belt or drive link and drive, accumulator links to each other with electromotor by power line, or accumulator and electromotor be assembled into one, and the power switch that is contained on the control stick links to each other with accumulator and electromotor by power line.

In order to improve the thick bar ability of cutting of rotating cutter, the sawtooth tooth depth of its rotating cutter or chopper sword length should be greater than 0.5 centimetres.

For anti-stopping bar obstructs stuck rotating cutter, it is staggered that the tapered plane of the sawtooth cutting edge of its rotating cutter or the adjacent cutting edge of chopper cutting edge is the phase anticlastic-surface.

In order to increase the safety of rotating cutter operation, be covered with a lampshade shape safety guard at rotating cutter, have one on the safety guard and advance rod notch.

The grasping control stick is laborsaving in order to work, and on the other relevant parts of the anterior nearly rotating cutter of loom at least one travelling wheel is installed downwards.

Swing on one side rather than disorderly when cutting down in order to control the stalk bar, swing to control lever on action bars, swing to the control lever rear end and link to each other with action bars by a connecting seat, its front end overhangs in the rotating cutter front upper place.

The utlity model has following advantage: 1, large-scale relatively combine comes its structure very simple, make and selling cost low, the farm machinery of affording, affording to use for vast farmers; 2, the speed of felling pesticide meridian crop is fast, efficient is high, through designer test, per hour can cut down about 1 mu of corn, jowar or sugarcane, is 4 times of artificial chopper felling efficient; 3, can cut down the pesticide meridian crop of various sturdy bar stalks, as the bar stalk of corn, jowar, sugarcane, ramie, soybean, cotton or the like pesticide meridian crop, widely applicable; 4, because travelling wheel and long control stick are housed, need not bend over during felling, and grasping is very not hard yet, has alleviated labour intensity greatly.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:

The shape and structure schematic diagram of 1 one kinds of rod cutting machines that electromotor is direct-connected with rotating cutter and accumulator separates of accompanying drawing;

Shape schematic diagram when 2 one kinds of control sticks of accompanying drawing are wooden ladder shape double link;

Shape and structure schematic diagram when accompanying drawing 3 rotating cutters are the discoid saw blade cutter of dark tooth;

Shape and structure schematic diagram when accompanying drawing 4 rotating cutters are the cross chopper.

As shown in Figure 1, present embodiment mainly is made up of control stick 9, rotating cutter 1, accumulator 4, electromotor 3, power switch 8 and power line 5, its control stick 9 is single pole or is that wooden ladder shape double link shown in Figure 2 (is handled more steady during the operation of double link control stick, particularly be not positioned at the control stick front end and be positioned at the control stick rear end or when middle, it is convenient to install electromotor and driving member thereof when electromotor 3); At the control stick front end rotating cutter is installed, rotating cutter is the discoid saw blade cutter of dark tooth shown in Figure 3 or is cross chopper shown in Figure 4; Its electromotor 3 also is contained in the front end of control stick 9, and rotating cutter 1 directly is installed in its rotating shaft; Its accumulator 4 is separated into a single-piece with action bars, electromotor, and it is linked to each other with electromotor 3 by power line 5; The power switch 8 that is contained on the control stick links to each other with accumulator and electromotor by power line, and power line preferably passes in the tube core of control stick through the control stick place; Accumulator then can be born the back the operator by after loading onto on the wrapper.

In order to improve the thick bar ability of cutting of rotating cutter, the sawtooth tooth depth Δ d1 of its cutter or the long Δ d2 of chopper sword should be greater than 0.5 centimetres, and general Δ d1 is chosen in about 3.5 centimetres, and Δ d2 should be greater than 3.5 centimetres.

In order to prevent that thicker bar from obstructing stuck rotating cutter, it is staggered that its tapered plane that revolves the adjacent cutting edge of the sawtooth cutting edge that cuts or chopper cutting edge is the phase anticlastic-surface.As shown in Figure 3, its a, c, e ... land be the plane cutting edge for inclined-plane cutting edge, the back side face to face, and b, d, f ... the land mouth be the inclined-plane cutting edge for plane cutting edge, the back side face to face; As shown in Figure 4, its A, C chopper cutting edge be the plane cutting edge for inclined-plane cutting edge, the back side face to face, and B, D chopper cutting edge is the inclined-plane cutting edge for plane cutting edge, the back side face to face.

Safety when increasing operation is covered with a lampshade shape safety guard 2 at rotating cutter, has a breach (general notch geometry such as half-open fan-fold paper fan-shaped) on the safety guard, so that the bar stalk that cut can be entered touch rotating cutter in the cover and cut off by rotating cutter.

For laborsaving and easy to operate, on the other relevant parts of the anterior nearly rotating cutter of loom, at least one travelling wheel 10 is installed downwards, so just the loom front can be supported on operation on the ground.This travelling wheel can be installed in the control stick forward position, also can be installed on the safety guard, can also be installed in below the electromotor outside, and travelling wheel 10 is to be installed in the control stick front end by the safety guard position by a vertical links in the present embodiment.

In order to control the bar stalk that cut off to down predominate, on control stick, be equipped with one to swing to control lever 6, this is swung to the control lever rear end and links to each other with control stick by a connecting seat 7, and its front end then overhangs in the front upper place of rotating cutter.
