Description

The corn cleaning-stubble machine

The utility model relates to crops cleaning-stubble machine tool.Be mainly a kind of harvest operation facility that are applicable to milpa together with the disposable removing of root stubble.

The clear stubble of corn mainly leans on hand plane at present, and labour intensity is big, and efficient is low, misses the farming season.Known Root digging machine tool has two kinds of corn harvesting machine, Root digging machines, and they rely on cam to stir planing tool, maybe will dig the stubble device and be contained on the power transmission shaft, its complicated in mechanical structure, cost of manufacture is big, operation fault rate height, it is big to dig the stubble positioning difficulty, particularly milpa once can not be removed together with the root stubble.

The purpose of this utility model provides a kind of corn cleaning-stubble machine that milpa can be removed together with the one-stop operation of root stubble.

The purpose of this utility model realizes by following measure: the corn cleaning-stubble machine, and it comprises back connection, bottom bracing, preceding support, reconciles diagonal brace, preceding connection, knife bar, hoe cutter, cutting knife, front support rod, stage clip, back stay, branch straw, rice crop-supporting plate, straw shift wheel, conveyer belt, girder frame, drive, driving-belt, the rope that rises and falls, driving wheel, gear-box and be connected and fixed part; It is characterized in that: be fixed on the back connection lower end that hangs the position behind the tractor and be connected with axle with bottom bracing; Fixedly connected with bottom bracing in the preceding support lower end that is fixed on tractor frame assembly front end, the preceding rear end that connects is connected with axle with bottom bracing, and preceding connection front end is connected with axle with knife bar, and knife bar is fixed on the girder frame, reconcile the diagonal brace lower end and be connected with axle with preceding connection rear end, the upper end is connected with axle with the girder frame; The hoe cutter is installed in the knife bar middle part, cutting knife is installed in the knife bar front end, rice crop-supporting plate cooperates connection with straw shift wheel, by front support rod and back stay rice crop-supporting plate and straw shift wheel are to the skewed top that is fixed on knife bar, front lower place, stage clip is fixed on the back stay, driving-belt connects drive, and drive connects with straw shift wheel again by gear-box, and the front end that the rope that rises and falls connects before being connected in.

Above-mentioned design constitutes the corn stubble cleaning device by knife bar, hoe cutter, cutting knife, front support rod, back spring, back stay, rice crop-supporting plate and straw shift wheel, this corn stubble cleaning device can be single group, two groups or three groups, be that hoe cutter, cutting knife can be single handle, two handle or three, knife bar by back connection, bottom bracing, preceding support, reconcile diagonal brace, preceding connection and girder frame and be installed on the tractor; Output shaft with tractor is used as power, and when carrying out forward, cutting knife cuts off ground plant weeds, and the hoe cutter has dug the root stubble at limited depth, reaches the effect that one-stop operation is once removed milpa together with the root stubble.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 3 is the plant conveying plant schematic top plan view of corn cleaning-stubble machine;

Fig. 4 is the preceding main schematic diagram of looking of the girder frame of corn cleaning-stubble machine.

Shown in Fig. 1～4: the utility model embodiment is three groups of corn stubble cleaning devices, and is installed on the tractor, is fixed on back connection 1 lower end that hangs the position behind the tractor and bottom bracing 2 and is connected with axle; Fixedly connected with bottom bracing 2 in preceding support 3 lower ends that are fixed on tractor frame assembly front end, before connect 5 rear ends and bottom bracing 2 and be connected with axle, before connect 5 front ends and knife bar 6 and be connected with axle, knife bar 6 is fixed on the girder frame 16, reconcile diagonal brace 4 lower ends and be connected with axle with preceding connection 5 rear ends, upper end and girder frame 16 are connected with axle; Hoe cutter 7 is installed in knife bar 6 middle parts, cutting knife 8 is installed in knife bar 6 front ends, divide straw 12, rice crop-supporting plate 13 to cooperate connection with straw shift wheel 14, by front support rod 9 and back stay 11 rice crop-supporting plate 13 and straw shift wheel 14 are to the skewed top that is fixed on knife bar 6, front lower place, stage clip 10 is fixed on the back stay 11, driving-belt 19 connects drive 18, drive 18 connects with driving wheel 21,22 mutually by gear-box 23 and with conveyer belt 15,17, and the rope 20 that rises and falls connects 5 front end before being bound up on to conveyer belt 15,17 with straw shift wheel 14 connections again.Hoe cutter 7 front ends are 30 degree acute angles, and the stage casing is indent arc edge, and afterbody left wing is 45 degree acute angles stretches, and the afterbody right flank is 135 degree obtuse angles.

The utility model can be designed to the single file corn stubble cleaner according to different service conditions, and the tennis partner holds up The tractor operation; Also can be designed to the duplicate rows corn stubble cleaner, with the supporting work of various tractor with small four wheels Already; Can also utilize this clear stubble technology, develop relatively large combined harvester. It is few to have equipment, becomes Background, simple in structure, supporting power is little, and the operation failure rate is low is easy to operate, uses safety, is convenient to push away The advantage such as wide.
