Description

The broaching tool harvester

The utility model belongs to the farm machinery class.

The harvesting facility are instruments of agricultural harvesting.Existing considerable peasant gathers in reaping hook, is bending waist, and harvesting speed is slow, and efficient is low, and labour intensity is big.A kind of V-type harvester is no longer bent over the peasant, and harvesting speed is fast, the efficient height.But because two blades become the V word to install, the rice bar concentrates on the undercutting of V word mouth and cuts.The V-type harvester can only lean on moment to push away with sudden force and cut, and is firmly big, can not cut at a slow speed, has a strong impact on use.The design's purpose is to overcome V-type harvester shortcoming, for the peasant provides a kind of simple in structure, light, laborsaving, with low cost, novel harvester tool that harvesting efficiency is high, effective.

The purpose of this utility model be achieved in that the broaching tool harvester by wooden fork plate, wooden fork prop up, fixed blade, movable blades, clamping plate, spring, handgrip insert and screw is formed.The wooden fork plate cuts into 3 otch, is cut into 4 wooden forks and props up.Wooden fork props up on the harvester left side, and fixed blade and clamping plate are arranged, and clamping plate are maked somebody a mere figurehead on it.Two wooden forks in the middle of the harvester prop up, and it is the end that fixed blade is arranged, and is movable blades above it, and the top is clamping plate on the movable blades.One spring is arranged on the clamping plate, and spring one end is fixed on the clamping plate, an end pushing tow movable blades knife back.The right wooden fork of harvester props up, and has only movable blades and spring.One end of spring then is fixed on wooden fork and props up.At the middle part, rear end of wooden fork plate is that handgrip is inserted handle.

The wooden fork of harvester wooden fork plate dual-side props up, and their inboard front ends are oblique outward, becomes horn mouth.It is straight that middle wooden fork props up the paracone both sides.The fixed blade right side is a blade, and front end is oblique outward, forms the toy trumpet mouth, and blade postmedian part is straight, and blade plane upwards.The blade of movable blades is to have several type teeth of setting one's teeth on edge, and teeth sword face is tiltedly long, with the fixed blade blade mutually interlock hand over into angle.The movable blades plane is downward, and its postmedian baroclines on the fixed blade plane that the adjacent wooden fork in a left side props up, under the clamping plate that the adjacent wooden fork in a left side props up.

The utility model technical characterictic is supplied with explanation by following legend

It is that separately the rice bar cuts with dispersion that wooden fork props up (1), and the negative usefulness that blade, clamping plate are installed.Screw (2) is blade, clamping plate to be fixed on wooden fork prop up.Fixed blade (3) and movable blades (4) are the cutters of cutting.Clamping plate (5) are that the control movable blades is lifted up on when cutting stress, keep the identical of its cutter plane and dead knife plane.Spring (6) plays tension force pushing tow movable blades with it, makes the follow-up teeth of movable blades, and the uncut rice of teeth (wheat) bar before can constantly cutting forms a plurality of cuttings force.Wooden fork plate (7) is the plate that collection otch and wooden fork prop up, and slides against the field with it.It is the handle that inserts handgrip that handgrip is inserted (8).

Most preferred embodiment

According to making wooden fork plate and the slotting handle of handgrip with steel plate processing or with the plastics notes among the figure.Become blade with thin steel band punching out, the back sharpening quenches.Spring is made into the path steel wire coil.Clamping plate are made with the sheet metal punching press.With sunk screw fixed blade, movable blades, clamping plate are installed in each wooden fork respectively as figure and prop up.Spring is contained on the clamping plate and the right edge wooden fork props up, and its an end pushing tow movable blades behind.

According to the made broaching tool harvester of present technique feature, utilize many wooden forks to prop up to disperse the rice bar to greatest extent, reduce the resistance and the influence of rice pole pair blade, favourable cutting.In the present technique, blade activity, blade are the type teeth of setting one's teeth on edge, and utilize the spring push blade to cut with broaching tool, make movable blades and fixed blade form better action and reaction force duty, forming a plurality of cuttings force (is that movable blades and fixed blade form movable angle.When cutting, in case the place ahead teeth fail to cut off the rice bar, the rice bar is that set one's teeth on edge teeth, two blades are that movable angle can slip into the rear teeth because of blade, and rear teeth spring-loaded is cut the rice bar that does not cut off again, eventually to cutting off.), therefore, broaching tool harvester good cutting effect need not to push away with sudden force to cut, and is laborsaving, practical.

Claims (6)

1, a kind of broaching tool harvester that utilizes several type teeth of setting one's teeth on edge of movable blades to carry out the broaching tool cutting, it is characterised in that: it by wooden fork plate, wooden fork prop up, fixed blade, movable blades, clamping plate, spring, handgrip insert forming, the left side wooden fork of harvester wooden fork plate has propped up fixed blade and clamping plate, two wooden forks in the middle of the wooden fork plate have propped up fixed blade, movable blades, clamping plate and spring, harvester wooden fork plate right side wooden fork has propped up movable blades and spring, and the wooden fork postlaminar part is that handgrip is inserted handle.
