Abstract
An overload safety protection structure for a rotary cutter tooth belongs to agricultural machinery; a cutter disc or a cutter tooth mounting seat is circumferentially and rotationally arranged on a driving shaft in the ways of radial and axial positioning, steel balls and a pressure spring are assembled in a radial through hole of the cutter disc or the cutter tooth mounting seat, a pressure adjusting screw rod assembled with a locking nut is rotationally assembled in the radial through hole of the cutter disc or the cutter tooth mounting seat, the two end surfaces of the pressure spring are respectively in contact fit with the steel balls and the pressure adjusting screw rod, the steel balls are in contact fit or detachment fit with a concave pit on the surface of the driving shaft, and a mounting hole is arranged at the circumferential edge of the cutter disc or the cutter tooth mounting seat; with the adoption of the overload safety protection structure, the damage fault of the cutter teeth in the overload situation can be effectively avoided and eliminated, the safety and working performance of a machine are improved, the maintenance and use costs of the machine are also saved, the structure is simple, the adjustment is convenient, and the use reliability is high.
Description
Technical field
The utility model belongs to agricultural machinery, relates generally to a kind of overload protection structure that is configured on the floods and droughts Tagayasu Den tillage operation facility.
Background technology
Used dry land stubble cleaner, rotovator, stubble ploughing, rotary tillage unit mahine and paddy field rotary tillage machine, its cutterhead or cutter tooth all are to be packed on the driving shaft.During operation, when the cutter tooth of high speed rotating runs into foreign material such as tree root in the soil, stone occasionally, light then often cause the damage of cutter tooth; When serious even cutter shaft and transmission mechanism are damaged; The operating cost of not only facility poor stability, and facility improves, and operating efficiency descends.
Summary of the invention
The purpose of the utility model is exactly the problem that exists to above-mentioned prior art, and design provides a kind of rotation cutter tooth overload protection structure, reaches the purpose of avoiding cutter tooth and facility to damage, improve operational security.
The basic design of the utility model is; The installation cutterhead or the cutter tooth mount pad of circumferentially rotatable on driving shaft, radial and axial location; Steel ball and compression spring are installed in the radial direction through hole on cutterhead or cutter tooth mount pad from the inside to the outside successively; The pressure adjusting screw of equipped locking nut revolves on the radial direction through hole that fits over cutterhead or cutter tooth mount pad, the compression spring both ends of the surface respectively with steel ball and pressure adjusting screw contact matching, steel ball cooperates with pit contact matching or disengaging on the drive shaft surface; Place, circumferential edges position at cutterhead or cutter tooth mount pad is provided with installing hole, so far constitutes rotation cutter tooth overload protection structure.
The utility model is simple in structure, and is easy to adjust, uses reliably, effectively avoids and eliminated cutter tooth damages fault under overload situations generation, improved the safety and the operating efficiency of facility operation use, saved facility and keeped in repair and use cost.

1, driving shaft, 2, steel ball, 3, compression spring, 4, locking nut, 5, pressure adjusting screw, 6, installing hole, 7, cutterhead or cutter tooth mount pad.
Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.A kind of rotation cutter tooth overload protection structure; The installation cutterhead or the cutter tooth mount pad 7 of circumferentially rotatable on driving shaft 1, radial and axial location; Steel ball 2 and compression spring 3 are installed in the radial direction through hole on cutterhead or cutter tooth mount pad 7 from the inside to the outside successively; The pressure adjusting screw 5 of equipped locking nut 4 revolves on the radial direction through hole that fits over cutterhead or cutter tooth mount pad 7; Compression spring 3 both ends of the surface respectively with steel ball 2 and pressure adjusting screw 5 contact matching, steel ball 2 is with driving shaft 1 lip-deep pit contact matching or break away from and cooperate, and locates to be provided with installing hole 6 at the circumferential edges position of cutterhead or cutter tooth mount pad 7.
When operation is used; Utilize the securing member group to be fixedly mounted on cutterhead or cutter tooth mount pad 7 sides stubble-cleaning cutter tooth or rotary tillage cutter tooth or the cutterhead that stirs the slurry cutter tooth or cutter tooth is housed through installing hole 6; Rotatablely moving of driving shaft 1 rotated through steel ball 2 drive cutterheads or cutter tooth mount pad 7 synchronously, accomplishes stubble-cleaning, the rotary tillage of cutter tooth or stirs the slurry operation.Stop moment when cutter tooth operation resistance overload when rotating, the driving shaft 1 of rotation is released steel ball 2 in its pit, and compression pressure spring 3 has guaranteed the safety of facility synchronously, has avoided the damage of parts.After cutter tooth overload resistance disappeared, steel ball 2 got in the pit of the driving shaft 1 that is rotated further rapidly under compression spring 3 thrusts, and cutterhead or cutter tooth mount pad 7 are rotated with driving shaft 1 synchronously, fulfiled assignment.Be screwed into or the degree of depth of pressure adjusting screw 5 in cutterhead or cutter tooth mount pad 7 radial holes of back-outing, accomplish and to combine the big or small adjusting of pressure between 3 pairs of steel balls 2 of compression spring and the driving shaft 1, to adapt to the anti-overload ability of different cutters tooth.Locking nut 4 can prevent the loosening of pressure adjusting screw 5.
