Description
Technical field
The invention belongs to agricultural machinery technological field, relate to a kind of drum type screw sawtooth moving knife hay cutter specifically.
Background technology
The drum type screw sawtooth moving knife hay cutter of prior art, generally comprise frame, power-driven mechanism, drum type brake cutting chamber and feeding mechanism, fixedly movable knife rack and knife section on the main shaft in cutting chamber are provided with spout in a side of cutting chamber, at spout ledger-plate are installed.Described knife section is common spiral yarn shaped, the bent tooth shape of straight knife and the straight tooth shape of straight knife etc.It is little that spiral yarn shaped blade has power consumption, high efficiency, and advantage such as it is more steady to work, but this moving knife manufacturing and the difficulty of whetting a knife are thrown and are sent that effect is little, rigidity is poor.As: the disclosed spiral vegetation chopper of China patent CN2504048Y, on the rotating shaft by driven by motor cutting edge is installed, said cutting edge blade is hook-shaped hook-type blade, said hook-type blade is formula arrangement in the shape of a spiral in turn on rotating shaft.Its shortcoming is a moving knife assembly heaviness, has increased body weight on the one hand, raises the complete machine center, influences the stability of machine operation, needs steel many on the other hand, the manufacturing cost height.And for example the disclosed forage grass spiral of China's patent CN2563913Y is sawed broken machine, and its knife section is that wheel carrier is installed on main shaft, the saw blade frame of mounting strap lead angle on this wheel carrier, the saw blade of fixed band sawtooth on this saw blade frame.The shortcoming of this structure requires saw blade must have certain elasticity just can be installed to the saw blade frame, so so will to require the saw blade good rigidly to cut very thin, the hard thing that this saw blade is very easy to be fed is smashed, and can not apply.
Summary of the invention
In order to overcome defective of the prior art, the object of the present invention is to provide a kind of drum type screw sawtooth moving knife hay cutter.
The object of the present invention is to provide a kind of simple in structurely, with low cost, power consumption is little, high efficiency, robust drum type screw sawtooth moving knife hay cutter.
The objective of the invention is to realize: a kind of drum type screw sawtooth moving knife hay cutter by following scheme, comprise frame, power-driven mechanism, drum type brake cutting chamber and feeding mechanism, the moving knife assembly is installed on the main shaft in the drum type brake cutting chamber, side in cutting chamber is provided with spout, at spout ledger-plate is installed, it is characterized in that: described moving knife assembly comprises wheel hub, spirality knife rest and cutter head, on the main shaft at drum type brake cutting chamber two ends, fix a wheel hub respectively, 2～8 spirality knife rest annular array also are separately fixed at by holding screw on the wheel hub at two ends, and there is draw-in groove in the outside of spirality knife rest; Some bottoms have fixture block one end to have the adjacent ground connection of cutter head of blade to be embedded in the draw-in groove, and the blade end of some cutter heads forms the spiral serrated edge.
As a kind of technical scheme of optimization, spirality knife rest fixing between two wheel hubs is 3～6.
Described its helical angle of spirality knife rest is 5～45 °, preferably 20～30 °.Helical angle described here is the tangent line of circular helix and passes through folded acute angle between the face of cylinder straight edge line at point of contact.
In order to form better sawtooth, the blade on the described cutter head is the linear pattern blade, and blade becomes 30～90 ° of angles, preferably 45～75 ° with the sagittal plane of main shaft
To throw careless effect in order improving, to be provided with in spirality knife rest inboard and to throw careless plate.
Parallel for the working face of realizing throwing careless plate with main shaft, improve and throw careless effect, described throwing grass plate is a right angle step shape folded sheet.
The advantage of drum type screw sawtooth moving knife hay cutter of the present invention is: 1. the blade end of some cutter heads forms the spiral serrated edge, changing straight cuts is spiral cutting, thereby the material shredding type that breaks traditions, improved operating efficiency greatly, save the energy, just can drive work of the present invention with very little motor.2. serrated edge has improved cutting efficiency on the one hand, makes simultaneously in the chopping process of material, plays certain broken effect of rubbing, and has increased the palatability of material, the availability of feeding height.3. the moving knife assembly mainly is made up of two wheel hubs, a plurality of spirality knife rest and some cutter heads, it is simple in structure, in light weight, making is easy, with low cost, because the moving knife assembly is rotatable parts, alleviated weight, help reducing the mechanical movement resistance, reduce body center, thereby improved the stability of mechanical movement.4. some bottoms have fixture block one end to have the adjacent ground connection of cutter head of blade to be embedded in the spirality knife rest draw-in groove, then the spirality knife rest is fixed on the wheel hub by holding screw, installation and maintenance is easily unclamped holding screw and at an easy rate the spirality knife rest is unloaded when whetting a knife or change cutter head.5. a further advantage of the invention is and be provided with the careless plate of throwing in spirality knife rest inboard, it can dish out the material of well cutting far.
