Description

Mini-size pneumatic sugar cane chopper

Technical field

The utility model relates to a kind of small-scale agricultural machinery, particularly a kind of machinery that is applicable to little plot harvesting sugarcane.

Background technology

China is existing at present is large-scale whole rod-type cane harvesting machine basically, though they can once finish and cut the tip, chop off the head, shell series of processes such as leaf, cleaning, Ji Dui, high efficiency, but because bulky, the complex structure of whole reaping machine, required mating power is big, and mobility is poor, and it is dumb to turn, not too suitable in sugarcane field, little plot, can not bring into play its advantage; On the other hand, at present China's cane harvesting machine is to the agriculture requirement height, must the sugarcane seeding row spacing relatively evenly, can normal operation under the not serious situation of lodging.And at fritter cane-growing regions such as China hills, hillside fields owing to influenced greatly by monsoon, crooked serious lodging, large-scale harvesting sugarcane machinery is inapplicable.Domestic similar small-sized harvesting sugarcane device has the Backpack type cane harvester at present, it drives the cutter that drives on the cutterhead by flexible axle by gasoline engine sugarcane is cut, it has characteristics such as flexible operation simple in structure, but the people need take on back of the body gasoline engine when it carries out operation, and gasoline engine vibration when work is bigger, and with noise and oil smoke, operating personnel's work under bad environment, easily make the people tired, thereby influence operating efficiency.

The utility model content

The purpose of this utility model provides a kind of miniature pneumatic type cane harvesting machine, utilizes characteristics such as its volume is little, in light weight, flexible and convenient operation can realize sugarcane is particularly gathered in the crops the more serious sugarcane of little plot lodging.

The utility model mainly comprises the pneumatic control part and cuts the sugarcane part.Pneumatic control partly comprises push buttonvalve, reversal valve and pneumatic tube, pneumatic control part with cut the sugarcane part and be connected by pneumatic tube; Cut sugarcane and partly comprise blow cylinder, frame, stationary knife, tool fixing frame, moving knife, movable knife rack, it is characterized in that described blow cylinder is fixed on the frame by the connecting rod that is mounted thereon, movable knife rack is fixed on the piston rod of blow cylinder, tool fixing frame is fixed on the frame, and moving knife, stationary knife are individually fixed on movable knife rack and the tool fixing frame.Described movable knife rack is provided with guide block.Frame is provided with a guide groove, and described guide groove is made up of two parallel long angle steel, is provided with a retaining pad in the guide groove end, and the guide block on guide groove and the movable knife rack forms a moving sets.Moving knife is done linear reciprocating motion and is cut sugarcane under the constraint of guide groove.

Owing to guide groove is arranged and on movable knife rack, is welded with a guide block on the frame of the present utility model, can make the guide block of movable knife rack and guide groove form moving sets like this, can be implemented in the rectilinear motion of the fixing moving knife of movable knife rack.This cutting mode is simple, the effective power height.Be provided with a retaining pad in the guide groove end, both can have guaranteed the registration of moving knife and stationary knife, can guarantee that again piston moves within range, play the effect that the protection piston is not hit; Pneumatic control of the present utility model simultaneously partly includes only push buttonvalve, reversal valve and pneumatic tube, so have simple in structure, light weight, flexible to operation, advantage such as control response speed is fast, is specially adapted to sugarcane field, little plot is gathered in the crops.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, the utility model is by pneumatic control part and cut sugarcane and partly form, and pneumatic control partly comprises push buttonvalve 12, reversal valve 11 and pneumatic tube 10; Cut sugarcane and partly comprise blow cylinder 9, frame 14, stationary knife 3, tool fixing frame 4, moving knife 2, movable knife rack 1.Blow cylinder 9 is fixed on the frame 14 by the connecting rod 15 that is mounted thereon, movable knife rack 1 is fixed on the piston rod of blow cylinder 9, tool fixing frame 4 is fixed on the frame 14 by the mode of welding, and moving knife 2, stationary knife 3 are fixed on movable knife rack 1 and the tool fixing frame 4 by bolt connecting mode respectively.Be welded with a rectangle guide block 16 on the described movable knife rack 1.Frame 14 is provided with a guide groove 5; described guide groove 5 is made up of two parallel

long angle steel

6 and 7, is welded with retaining pad 13 in the guide groove end, both can guarantee the registration of moving knife 2 and stationary knife 3; can guarantee that again piston moves within range, play the effect of protection piston.Guide block 16 on guide groove 5 and the movable knife rack 1 forms a moving sets, and moving knife 2 is done linear reciprocating motion and cut sugarcane under the constraint of guide groove.Pneumatic control part with cut the sugarcane part and be connected by pneumatic tube, pass to push buttonvalve 12 and reversal valve 11 by the Compressed Gas that source of the gas produces respectively by pneumatic tube, unlatching control reversal valve 11 by push buttonvalve 12 is changing compressed-air actuated direction, thereby the moving knife 2 that the piston rod 8 on the blow cylinder 9 is driven on the movable knife racks 1 moves reciprocatingly.

Moving knife 2 of the present utility model and stationary knife 3 can adopt different shape, as arc, zigzag etc.

More than be embodiment of the present utility model, according to the disclosed content of the utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into the scope that the utility model is protected.
