Specific embodiment

Technical solution of the present invention is further elaborated below in conjunction with the accompanying drawings：

It is prior art knife-tooth structure figure shown in Fig. 1, by taking BACKHUS knife-tooth structures as an example, its blade (3) is installed in flat Row broken line form is fixed on the tool rest (2) on roller external cylindrical surface (1), and parallel fold lines described here refer to the phase for constituting broken line Parallel two-by-two every line segment, the seat surface for installing blade (3) is formed an angle with roller external cylindrical surface (1) bus, and each blade (3) is installed Perpendicular to bus that is, parallel to tangential, the blade (3) on tool rest (2) is favoured tangentially for the part connected between seat surface, This is conducive to the soil cleared up on blade (3), perpendicular to the part of bus then as the bearing rib of blade (3) seat surface, in order to Avoid the deposition of cutter tooth root, the root of tool rest (2) should not according to the inner corner trim (5) made the need for cutting anterior angle less than 90 degree, and Anterior angle demand is formed with bending blade (3), and bending needs enough length to adapt to the abrasion demand of long period, is suspended in Tool rest (2) dogleg section more long outward loses the support of tool rest (2), it is meant that blade (3) needs thicker thickness to ensure Enough intensity, blade (3) and the connection of tool rest (2), then cause that the one side exposure that blade (3) meets mud has coupling part (bolt Head), the inner corner trim (5) that this part and tool rest (2) bending part are formed turns into the seed of trouble of deposition jointly.

Tool rest shown in Fig. 2 (2) is rolled tiltedly to mud is met, and blade (3) uses hard thin plate, thickness to be preferred less than 4mm, can be in knife Length is leant out with wear adjustment in seat (2), blade (3) naturally form the anterior angle for being easy to cut soil, knife when soil is cut Piece (3) can still form negative relief angle unavoidably upon wear, but act that the action length in the face for smearing pressure is very short because blade is thin, and it is to mud Soil smear pressure effect be not and fill and lead up tear soil formed male and fomale(M＆F), will not more form compacted lift, compacted lift no longer occurs, and makes Obtain contact of the blade (3) when soil is cut to reduce, thus abrasion can slow down, while cutting force also therefore decline, blade (3) the thin approach for being to improve cutting, but it is also relatively flexible, it is that this is provided with back bracket (4), back bracket (4) at the back side of blade (3) Support blade (3) is both with the effect of tool rest (2), back bracket (4) then can easily adjust support according to the demand of cutting depth Depth, the demand of anterior angle causes the dark corner that the root of cutter tooth forms relative narrowness and gets deeply stuck in, and is easily stranded in soil This, then because the adhesiveness of soil piles with whole inner corner trim (5), so as to cover blade (3) anterior angle, influence soil incision is set for this Inner corner trim (5) with non-adhesion behavior (comparatively, it is difficult to accomplish absolutely not to glue, taking from the not viscous concept of non-stick pan), inner corner trim (5) a rounding off curved surface is formed and between outer surface of cylinder in blade (3), during soil is cut, soil is through sword for soil Mouth cutting is above squeezed into being received in inner corner trim (5) concave surface by blade (3), after the completion of cutting, is entered by cutting edge there is no soil, Conversely, soil is spued by cutting edge under the influence of centrifugal force, pass in and out cutting edge and obtain self-cleaning, compared to prior art cutter tooth The right angle of root, the angle that inner corner trim (5) rounding off concave surface is formed between the normal direction and blade of blade (3) boundary is more than rubbing Wipe angle, during soil is squeezed into by cutting, soil easily opposed concave slides, especially when meet mud surface use not Viscous material (7) so that inner corner trim (5) concave surface is cleared up.Inner corner trim (5) is filled with dark corner as packing material, meanwhile, in the moon The unit of connection is provided in angle (5), may be used to fix blade (3) and back bracket (4).

Fig. 3 show composite construction inner corner trim (5), by constituting inner corner trim (5) sunny side while being also the non-adhesive material of meeting mud face (7), support the rigid tile (8) of non-adhesive material (7), tile (8) is supported fixation while being also used for fixing blade (3) The composition such as support presser feet (9), non-adhesive material (7) can use polytetrafluoroethylene (PTFE), other fluoroplastics or its material modified and poly- second Alkene etc. is difficult the material with soil adhesion, and non-adhesive material (7) is relatively soft material, needs have certain rigid material for this Made tile (8) structural support of material shapes it, and non-adhesive material (7) can use technique for sticking with the connection of tile (8), Using painting ferryman's skill, or using riveting or bolt connection, it can also be made to be fixed on tile (8), technique for sticking can be obtained Moderate thickness, riveting or bolt connection need thicker non-adhesive material (7), and tile is curved surface so that non-adhesive material (7) shapes The curved surface for constituting afterwards forms the knot in rounding off face, tile and non-adhesive material (7) between blade (3) and roller external cylindrical surface (1) Conjunction face is concave surface, and the fixed installation for setting support feet for tile is spaced a distance on the another side of tile that is, convex surface, Support feet is used to fix blade simultaneously, carries the effect of the pressing plate of fixed blade, so support presser feet (9) is called, support Presser feet (9) is fixed on the convex surface of tile, can be fixed using riveting, bolted on connection, bonding or welding manner, supports presser feet (9) board making can be used, the thickness direction of sheet material is the length direction of tile, and support presser feet is fabricated to polygonal panel, its Middle one side is curved side, while being straight line or curved side, the curved surface where curved side is combined with tile, where straight line or curved side Face combined with blade.

It is that overall structure inner corner trim (5) is illustrated shown in Fig. 4, inner corner trim (5) can adopt integral plastics and be made, but still need to appropriate Position, setting nut spaced apart etc. for the connector (10) that connects, can be produced in the presence of bolt enough Enough pressure fixing blades (3) and back bracket (4).

Blade structure shown in Fig. 5 is composite blades, is made up of non-adhesive material (11) and rigid board (12), is not glued Material (11) for before blade (3) i.e. cut when meet mud face.The direction of motion of its opposing roller is radially when soil is dished out Away from centre of the drum, for the blade arrangement form with anterior angle, soil falls on inclined-plane when moving radially like soil Slip, the acceleration when coefficient of sliding friction between soil and blade and viscous glutinous characteristic determine that soil is dished out, slip rubs Wiping coefficient is smaller, and non-stick nature is stronger, and acceleration is bigger, and it is more remote that soil is dished out, therefore using the structure with non-adhesive material Form, soil is dished out after being conducive to cutting, but non-adhesive material (11) relative rigid sheet material (12) softer, for same intensity knife For piece, the thickness of blade is increased, reduce the sharpness of cutting edge, be unfavorable for cutting.
