Abstract

The utility model relates to a cutter shaft type cotton stalk reaper whose principal character is that a machine frame is hinged with the tractor fender-guard through a suspension pin. The front end of the machine frame is provided with a cutter shaft. The back end of an oscillating arm is hinged on the machine frame, and the front end of the oscillating arm is provided with a grain lifter. The machine frame is provided with a gear box. The output power of the tractor through the gearbox conveys to the cutter shaft and the grain lifter by a transmission chain and a triangular belt. The transmission chain and the triangular belt can rotate according to the definite velocity ratio to finish the movement of lifting the grain. The utility model is free from the limitation of the row spacing or straightness for sowing the cotton. It can lift and collect the cotton stalk to throw out of the earth surface in the operating width. The cutter shaft type cotton stalk reaper with high work efficiency can satisfy the needs of the agriculture.

Description

The rotary cutting shaft type gatherer for cotton firewood

The utility model relates to a kind of agricultural machinery, particularly a kind of gatherer for cotton firewood.

Cotton bavin results are a labour intensity height, inefficient work in vast cotton region.The gatherer for cotton firewood of prior art has two classes: the one, and relative rolling type (or clamping chain type) promptly with cotton bavin being clamped to rolling (or paired chain) of rotating, and utilizes its rotation that cotton bavin is extracted; The 2nd, jaw clamping type promptly utilizes gripper clamp that cotton bavin is clamped, and along with cotton bavin is extracted in the forward travel of unit and the rotation of gripper clamp.These two kinds of reaping machine common drawback are: all be subjected to the restriction of the line-spacing and the cotton linearity of going of sowing cotton seed, and its operating efficiency is extremely low, even at all can't operate as normal.

The purpose of this utility model is to provide a kind of line-spacing of sowing cotton seed and rotary cutting shaft type gatherer for cotton firewood that linearity limits and has higher operating efficiency of not being subjected to.

The purpose of this utility model is achieved in that frame is articulated on the tractor bumper by suspended axle, and gear-box is installed on the frame and by conveyer belt and connects with the tractor dynamic power output wheel; The frame front end is equipped with cutter shaft, and cutter shaft connects with gear-box by driving-chain; The swing arm rear end is articulated on the frame, and front end is equipped with grain lifter, and grain lifter realizes that by belt wheel, V-belt and gear-box power transmits; Fan-shaped support arm is fixed on the frame, has arcuate socket on the fan-shaped support arm, and set bolt passes this arcuate socket and is tightened in the swing arm; Between cutter shaft back, machine frame at two sides, be provided with gathering unit; Also by support the landing rope sheave is installed on the tractor bumper, rope one end is fixed on to be walked around the landing rope sheave then and connects with elevator on the frame.

The purpose of this utility model can also following manner realize:

Cutter shaft is made up of with being fixed on the knife rest on its circumference and being fixed in the knife rest cutter central shaft.

Cutter shaft upper tool post and blade are two rows, three row or four rows.

The blade of the blade on the cutter shaft is a zigzag.

Because the utility model adopts the cutter shaft structure, at work, be not subjected to the width of the line-spacing of sowing cotton seed, any restrictions such as linearity of cotton row, cooperate grain lifter reasonably to press the standing grain angle, cotton bavin can be extracted smoothly, and have higher operating efficiency, satisfied the demand of agronomy substantially, alleviated peasant's labour intensity greatly.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the right view of Fig. 1.

Fig. 3 reaping machine principle schematic.

The structural representation of Fig. 4 cutter shaft.

The utility model and tractor and the supporting use of other tractor are installed on the head front.Can be divided into several major parts such as cutter shaft, grain lifter, gathering unit, elevator and transmission system on the structure.

Frame 1 is connected with the tractor bumper by suspended axle 4, and frame 1 can turn an angle around suspended axle 4, so that when not working cutter shaft 12 is raised up.Gear-box 3 is installed on the frame 1, is delivered to gear-box 3 by belt, after slowing down, pass to cutter shaft 12 and grain lifter 9 by driving-chain 2 and V-belt 7, belt wheel 8 by gear-box 3 respectively then by certain speed ratio by the tractor dynamic power output wheel.Cutter shaft 12 is installed on the front end of frame 1, is its circumference welding 2 to 4 knife rests in central shaft outer on the structure, fixed blade again on knife rest, and the effective length of cutter shaft is the working width of reaping machine.For increasing work efficiency, the blade cunning can not effectively pull up cotton bavin when preventing to pull out cotton bavin, blade can be made zigzag.Swing arm 6 rear ends are connected with frame 1 by a hinge, swing arm 6 front ends are equipped with grain lifter 9, swing arm 6 can be adjusted by the fan-shaped support arm 11 that is fixed on the frame 1 with the angle of frame 1, promptly unclamp set bolt 10, swing arm 6 is turned to tighten set bolt 10 again after the proper angle to get final product.Gathering unit 13 is connected on the machine frame at two sides, be positioned at cutter shaft 12 back, grain lifter 9 below.Elevator is installed on the tractor can drive a capstan winch by outputting power, walks around the landing rope sheave 5 that is installed on the bumper by rope then and is connected in angle on frame 1 rear side.

Operation principle: tractor dynamic power is delivered to cutter shaft and grain lifter respectively through gear-box, the two is rotated according to certain rotating ratio, when cotton bavin touches the cutter shaft knife-blade of rotation, grain lifter is held up cotton bavin just and is determined position (angle), along with the forward travel of unit and the rotation of cutter shaft, blade is cut cotton bavin certain depth gradually and is upwards pulled up simultaneously.Cotton thereupon bavin topple over backward and by gathering unit will topple over (extracting) back cotton bavin be gathered into certain thickness and width, throw on ground.
