Description
Technical field
The present invention relates to a kind of tooth heads of agricultural machinery, belong to farm machinery parts technical field.
Background technology
The extensive application of mechanization of agriculture, improves level of agricultural production, for improving farmers' income, reduces labor intensity
It is of great significance；Current agricultural machinery includes harvester, grass trimmer, ridger, rotary cultivator, seedling transplanter, ditching machine
Etc., these Agricultural Machinery Designs are mostly used for the contact with soil, and soil has lump soil, also have and are embedded with stone in the soil
Block or iron block, therefore when these farm machineries touch these hard soil or stone or iron block, it can connecing because of farm machinery
Tactile parts are not hard enough or insufficient strength etc., and causing the damage of parts at the damage of farm machinery, especially one will bring
Repair and update etc., not only lose time, but also bring the increase of use cost, therefore, must match somebody with somebody on some farm machineries
Special dentation body is put, is protected safe to use with soil contact component on farm machinery.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and offer is a kind of simple in structure, uses installation side
Just, structural strength is good, wear-resisting, impact resistance, the tooth head of the agricultural machinery of service life length.
The purpose of the present invention is come what is completed, a kind of tooth head of agricultural machinery, it includes one by following technical solution
The strip body of arc, the concave surface of the strip body, raising up along the centre in strip direction has one with identical
The central elongate raised line of concave arc, the both ends end face of the strip body are transverse plane upward, and in described one end
Weldering is connected at least one layer of hard alloy layer on transverse plane；The convex of oriented both sides evagination is formed among the central elongate raised line
Side, and connect respectively with the central elongate raised line side arc at chimb both ends, form intermediate one section of broadside raised line, the broadside
There are two the location notch holes being arranged side by side for the concave upper surface setting of raised line.
As preferred：The both ends transverse plane of the strip body raises up after including the intermediate extension by central elongate raised line
, raised line transverse plane that be higher by strip body transverse plane, formed similar triangle, be uneven operative end surface；The strip
The intermediate two sides of body are respectively arranged with the arcuate flanks that inside location notch hole is shunk；The convex surface of the strip body is
Smooth flat；Described two location notch holes for being arranged side by side are ladder slot, the wide area slot in top of two location notch holes
It is connected at one end together.
The invention belongs to improvements over the prior art, it has simple in structure, and easy to install and use, structural strength is good, resistance to
The features such as mill, impact resistance, service life is long.
Description of the drawings
Fig. 1 is the positive structure schematic of the present invention.
Fig. 2 is the A of Fig. 1 to structure diagram.
Fig. 3 is the B of Fig. 1 to structure diagram.
Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail：Shown in Fig. 1-3, a kind of agriculture machine of the present invention
The tooth head of tool, it includes the strip body 1 of an arc, the concave surface 2 of the strip body 1, along strip direction
Between raise up have one have identical concave arc central elongate raised line 3, the both ends end face of the strip body 1 is upward
Transverse plane 4, and on the transverse plane 4 of described one end weldering be connected at least one layer of hard alloy layer 5；The central elongate raised line 3
Among form the chimb of oriented both sides evagination, and connect respectively with the central elongate raised line side arc at chimb both ends, shape
Into intermediate one section of broadside raised line 6, there are two the location notch holes 7 being arranged side by side for the concave upper surface setting of the broadside raised line 6.
Shown in figure, the both ends transverse plane 4 of the strip body 1 includes centre by upward convex after the extension of central elongate raised line
Rise, raised line transverse plane 42 that be higher by strip body transverse plane 41, form similar triangle, be uneven operative end surface；Institute
The intermediate two sides for stating strip body 1 are respectively arranged with the arcuate flanks 8 that inside 7 direction of location notch hole is shunk；The strip sheet
The convex surface of body 1 is smooth flat 9；Described two location notch holes 7 for being arranged side by side are ladder slot, two location notch holes
The wide area slot in top be connected at one end together.
Using hard alloy blocks, face is welded the present invention at one end, substantially increases the wearability and service life of product；
Special shape and the design of location notch hole and groove, are easily installed and fix, while also improve work efficiency.
