Abstract
The invention provides a disc type cutting device of a forage grass harvesting flatting machine. The disc type cutting device comprises a power transmission shaft, a hanging frame, a protective cover, a cutting disc hanging frame, a swath board, a cutting disc main shaft, an intermediate propeller shaft, an elliptic spherical surface cutting disc, a driven cutting disc shaft, blade supports, blades, a transmission box, a transmission gear and a protective supporting plate. When power is transmitted to the power transmission shaft, the power transmission shaft rotates at high speed to transmit the power to the cutting disc hanging frame so as to drive a cutting disc to rotate together, and a gear of the transmission box transmits the power to drive other cutting discs to rotate; large end surfaces and small end surfaces of adjacent two cutting discs are always vertical mutually so that motion trails of the adjacent blades are mutually superposed and forage grass is enabled not to be omitted in a harvesting process; and the blades are arranged in a free-swinging knife manner and rotate at high speed along with the cutting discs so that the blades harvest the forage grass under the action of a centrifugal force and are bounced off to prevent cutting bodies and transmission components from being damaged when meeting hard objects or stones in the harvesting process; and therefore, the disc type cutting device disclosed by the invention has a self protection function.
Description
Technical field
Patent of the present invention belongs to agricultural machinery technological field, particularly a kind of disc type herbage harvesting flatting mill cutter sweep.
Background technology
Along with the development of livestock breeding, the increase of the phytophagy draught animals such as ox, sheep cultivation quantity, the cultivated area of herbage also increases thereupon, and particularly the cultivated area increase of high nutrition, high protein, economical herbage-Alfalfa is more remarkable.Alfalfa is described as King of Pasture with high-quality, high protein, Alfalfa is in the nutritious phase, usually moisture content is more than 70%, only enrich rapidly dehydration processing of phase at forage nutrition, keep to greatest extent nutrition and safe storage, could effectively improve grazing rate and the digestibility of material, thereby improve the commodity value of herbage, also be convenient to long-distance transport and outlet.Clover mostly is establishing in large scale, and every batch of harvesting time only has about 15 days usually, so the clover harvest time it is pressed for time.
Herbage harvesting flatting mill can effectively flatten herbage stem stalk in harvesting; can improve the rate of drying of herbage more than 50%; can make stem stalk and blade reach simultaneously required moisture content during collection; shorten herbage in the drying time on grassland; and protein loss in the minimizing herbage; improve the forage grass quality, protected to greatest extent nutritional components not run off, for following process is provided convenience.Operation by herbage harvesting flatting mill has improved the do mechanization operation degree, has reduced labour intensity, has improved labor productivity, has reduced the loss that herbage falls to cutting.
Summary of the invention
Disc type herbage harvesting flatting mill cutter sweep is to the strong adaptability on grassland.This device has the maintenance of being easy to, and blade adopts the mounting means of flail knife, and blade can flick when running into hard thing or stone, can not injure cutter hub.Cutterhead and blade have the advantages that to be easy to change.
Patent of the present invention solves the technical scheme that its technical problem adopts: comprise power transmission shaft, pylon, protective cover, cutterhead hanger, swath board, cutter spindle, intermediate propeller shaft, oval sphere cutterhead, driven cutter axis, blade support, blade, transmission case, travelling gear and protection supporting plate.It is characterized in that power transmission to power transmission shaft, power transmission shaft is limited in the pylon, limits the pylon of power transmission shaft and the pylon of the other end and guarantees that transmission case is in relative position; Protective cover is installed on the pylon, and its function is to prevent that herbage from entering cutterhead hanger top and forming winding, thereby affects the normal rotation of cutterhead hanger; Cutterhead hanger and cutterhead firmly are installed together, and have the effect of supporting up-down structure and transferring power; Swath board is installed on the cutterhead hanger outward flange, and its function is to guarantee that the herbage that the cutter sweep two ends cut down can be drawn in the cutterhead surfaces of revolution, along with the High Rotation Speed of cutterhead hanger and cutterhead, harvested herbage is dished out backward; Adopt oval sphere cutterhead can guarantee that the large and small end face interleaved operation of adjacent two cutterheads does not leak herbage and cuts, can make again harvested herbage under the High Rotation Speed of cutterhead, can dish out along the sphere tangent line of cutterhead, for lower one flattening process ready, according to the size of swath, many group cutterheads can be set; Two blade supports are installed on each cutterhead, blade is to install with the form of flail knife by the blade bearing pin in the blade support, blade can be in blade support inward turning turnback, if run into hard thing or stone in operation process, blade can be dodged in deflection, so just avoided the breakage of blade, protected blade, each blade is operated at two faces, when a sword surface wear of blade is serious, can overturn to install and cut with another sword face, improve the service efficiency of blade; The rotation of oval sphere cutterhead is to transmit to realize by the gear in cutter axis and the transmission case; The height dimension of transmission case directly has influence on the harvested cutting height of herbage; The protection supporting plate has been installed below the transmission case, has been prevented that ground projection in misoperation or the operation process from causing the direct impact to transmission case.
During work, power transmission is to power transmission shaft, the High Rotation Speed of power transmission shaft passes to the cutterhead hanger, and the band movable knife disc rotates together, the cutterhead that is installed in the power transmission shaft below is the active cutterhead, remaining cutterhead is from movable knife disc, initiatively the rotation of cutterhead is by the gear transmission of transmission case, drive is from the rotation of movable knife disc, the large and small end face of adjacent two cutterheads remains vertical angle, make adjacent blade movement axis overlapped at adjacent, guarantee in cutting herbage process, not leak and cut; Blade adopts the dress mode of sending out of flail knife, and along with the High Rotation Speed of cutterhead, blade cuts herbage under the effect of centrifugal force, and when running into hard thing or stone in cutting process, blade can be flicked, and avoids damaging cutter hub and drive disk assembly, has the self-protection effect; Adopt oval sphere cutterhead, can make herbage after the cutting along with the High Rotation Speed of cutterhead, dish out backward with certain height along the sphere tangent line of cutterhead, for lower one flattening process ready; In herbage harvesting process, when running into being uneven of ground, transmission case may occur and scrape the ground phenomenon, so in the transmission case bottom protection supporting plate is installed, be used for protecting transmission case.
