Description
Technical field
The present invention relates to a kind of hammehead structure for hammer mill, belong to hammer mill technical field.
Background technology
The tup of hammer mill is the critical component that direct strike enters crusher chamber ore, due to hammer head of hammer crusher
It is to be hinged on the bearing pin for being suspended on rotor block, during tup strike ore, impulsive force will be acted on the tup point of impingement；Due to existing
There is the hammer head of hammer crusher scope of attack in technology generally rectangular cross-section or trapezoidal, thus the every bit of the scope of attack is likely to implementation
Strike to material, the position of impulsive force can usually deviate the center of impact of setting, cause to produce collision counter-force on bearing pin,
Its consequence is to produce detrimental resistance square, shortens rotor bearing service life, or even can damage bearing pin.
In addition, in the direct contacting material of the tup scope of attack, stress is the most direct, therefore, the planform of tup and its
Hardness and intensity are also related to the broken effect of service life and material of tup, and the hammehead structure that existing disintegrating machine is used
Also there are above-mentioned many deficiencies, urgent need will carry out corresponding technique improvement.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and provide a kind of simple in construction, use installation side
Just, use intensity is high, and anti-wear performance is good, the grinder hammerhead of service life length.
The purpose of the present invention is completed by following technical solution, a kind of grinder hammerhead, including is fixed on broken
The hammer handle of machine bearing pin and be fixedly connected or be made into integration with the hammer handle, tup body for hitting material, described tup
Body is in the working face that before square block, the rotation just of the tup body and upper plane is strike material, before the working face is to rotate just
Respectively backward and the strip groove being adjacently positioned is vertically provided with centered on the intersecting corner of face and upper plane, and in the bar shaped
Hard alloy blocks or hard alloy bar and firm welding are embedded with groove；On the tup body surface face of the working face both sides and
Technique for overlaying is respectively adopted on down extended spot surface before the rotation just of tup body and is provided with least one layer of high hardness wear-resisting material
The bed of material.
As preferred：The axle sleeve that described hammer handle is provided with pin shaft hole in the middle of one is constituted, and described axle sleeve connects by one
Cervical part of esophagus is connect to connect described tup body；The strip groove that working face corner on the tup body is set is to set in the diagonal, its
In the polylith hard alloy blocks or the oblique evagination of hard alloy bar that are embedded, and formed and upper plane and rotated concordant two before just
Side, the depth of working face corner strip groove is more than the other parallel strip grooves set on working face.
As preferred：Parting bead has been split in the middle of described strip groove, and each strip groove is divided into multiple pieces
The hard alloy being embedded with shape recessed groove, each recessed groove in a hard alloy blocks, and each strip groove is block-shaped and big
It is small identical, it is provided with step below the working face before the rotation just and inside contracts joint face and transitted to down through arc joint face
The connected hammer handle in portion；The high hardness wear-resisting material layer scope of the working face both sides tup external surface is with working face strip groove
Below, the region more than the end line in lower work face surrounded.
The invention belongs to improvements over the prior art, it has simple in construction, easy to install and use, use intensity height, resistance to
Grind performance good, the features such as service life is long.
Brief description of the drawings
Fig. 1 is the side structure schematic view of the present invention.
Fig. 2 is the positive structure diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Fig. 1, shown in 2, a kind of crusher hammer of the present invention
Head, including be fixed on the hammer handle 1 of disintegrating machine bearing pin and be fixedly connected or be made into integration with the hammer handle 1, for hitting material
Tup body 2, described tup body 2 is in square block, the rotation of the tup body 2 just above 3 and upper plane 4 for strike material work
Make face, the working face by rotate just above 3 and the intersecting corner of upper plane 4 centered on respectively backward and be vertically provided with adjacent cloth
The strip groove 5 put, and it is embedded with the strip groove 5 hard alloy blocks 6 or hard alloy bar and firm welding；It is described
Built-up welding is respectively adopted on the surface of tup body 2 of working face both sides and before the rotation just of tup body on 3 down extended spot surface
Technology is provided with least one layer of high hardness wear-resisting material layer 7.
Shown in figure, the axle sleeve that described hammer handle 1 is provided with pin shaft hole 8 in the middle of one is constituted, and described axle sleeve passes through one
Connection cervical part of esophagus 9 connects described tup body 2；The strip groove that working face corner on the tup body 2 is set is to set in the diagonal
Put, wherein the polylith hard alloy blocks 6 or hard alloy bar that are embedded are in oblique evagination, and before formation and upper plane 4 and rotation just
Two concordant sides of face 3, the depth of strip groove 5 that the working face corner is set is other parallel more than what is set on working face
