Description

Hay cutter

Technical field

The utility model relates to a kind of stockbreeding machine, is specially a kind of hay cutter that is used for the herbage chopping.

Background technology

The upper and lower feeding roller of existing hay cutter is by mutual meshed transmission gear, and it is unreasonable to add that the feed hopper exit width is provided with, thereby gear slip teeth, jumping tooth often takes place and roll up problem such as careless card machine; Secondly, the length that existing hay cutter is regulated the herbage cutting by gearbox, it installs complicated, the cost height; In addition, existing hay cutter is not suitable for the cutting straw, and discharging is not smooth, and putty card machine problem is often arranged.Above-mentioned these deficiencies have had a strong impact on the operating efficiency and the applicability of existing hay cutter.

The utility model content

The purpose of this utility model will overcome above-mentioned deficiency exactly, and the device that provides a kind of and do not have slip teeth, jumps tooth and roll up careless card machine, regulates the herbage Cutting Length is easy, cost is low, especially be fit to the stifled hay cutter of chopping straw and the unimpeded nothing of discharging.

For achieving the above object, the technical solution of the utility model is, this hay cutter comprises the cutting-cylinder of frame and rack-mounted motor and top thereof, be installed in going up of cutting-cylinder rear and feed roller, under feed roller, near the described roller of feeding down, be provided with the axle of passing a bridge, at a described end of passing a bridge axle the be meshing with each other tumbler gear of transmission of gear with the described roller of feeding down is housed, the described cutting-cylinder of described driven by motor, cutting-cylinder drives described gap bridge axle and last feeding roller respectively, feed the gear of roller down by the tumbler gear transmission of axle one end of passing a bridge, make down the feeding roller feed the opposite direction rotation of roller up, pass through the sprocket wheel chain drive between described cutting-cylinder and the last feeding roller, and the axle of the two is non-vertical relation up and down.Like this, because upper and lower feeding roller is respectively by transmission, rather than mutually with gear drive, thereby fed herbage when pushing jack-up when last feeding roller, with regard to the problem that its mutual gear slip teeth can not occur, jump tooth and roll up careless card machine.

On described near the feeding roller, with last feeding roller the axle non-vertical up and down position on, be provided with speed governing gap bridge axle, on the axle of this speed governing gap bridge axle and described cutting-cylinder, be respectively equipped with at least with the belt grooves of 2 different-diameters or the cone pulley of sprocket wheel, by the described cutting-cylinder of described driven by motor, by cutting-cylinder drive speed-adjusting gap bridge axle, feed roller and gap bridge axle in the transmission respectively by speed governing gap bridge axle again, the tumbler gear transmission of this axle one end of passing a bridge is the gear of feeding roller down, speed governing is passed a bridge between axle and the last feeding roller mutually with the sprocket wheel chain drive, hang over by belt or chain on the belt grooves or sprocket wheel of different-diameter on described two cone pulleies, the rotating speed of described speed governing gap bridge axle is changed, and then on changing, feed the rotating speed of roller down, thereby just can change the length of herbage cutting as required easily.

Back at the described roller of feeding down, be provided with feed hopper, described feed hopper near the width of the down outlet of feeding roller less than last feeding roller and the width of feeding the spout that forms between the roller down, the both sides of the bottom blade plate between described upper and lower feeding roller and the cutting-cylinder with above be respectively equipped with and prevent to feed the plate washer that herbage scatters.

As another kind of improvement the of the present utility model, below described feed hopper, be fixed with arm-rest frame, this arm-rest frame front end and described frame form dismountable movable being connected.

As improvement of the present utility model, in the front lower place of described cutting-cylinder, i.e. between the outlet of the herbage particle of cutting-cylinder and chopping, be provided with the feeding fan, this feeding fan is driven by cutting-cylinder by described motor, or is directly driven by motor.

The upper and lower feeding roller of the utility model hay cutter is not mutually with gear drive, but respectively by transmission in opposite directions, its feed hopper exit width is less than the width of the spout of upper and lower feeding roller formation, thereby can not occur going up slip teeth that the feeding roller brings, jump tooth and rolling up problem such as careless card machine because of herbage feeding extruding jack-up, improved careless efficient of hand hay cutter and effect; It is particularly suitable for shredding straw, and can regulate the rotating speed of upper and lower feeding roller as required, with this length of regulating the herbage cutting, has adapted to the different needs of ox, sheep and grass silage etc. preferably, and has realized that the device of this adjusting is very easy, and cost is low; Blow by fan and to scrape, make the unimpeded nothing of herbage discharging chopped stifled; The feed hopper and the arm-rest frame of this hay cutter are fixed into integral body, make feed hopper not yielding, and make to economize material, and its arm-rest frame be movable detachable, use very conveniently, and the time spent in spare time can reduce and takes up room.
