Abstract
The utility model aims to provide a novel flat pick which is reasonable in structural performance, is provided with a wear-resistant tooth head, and is widely suitable for construction environments and long in service life. The tooth head is designed to be of a hook head flat shape. A hard alloy body brazed on the tooth head is in a wedge cone shape, and a water pore slot is formed in the tail part of the tooth head at the same time. Rubber and a fall-preventing plastic key are respectively embedded into a key groove formed in a tooth handle. By adopting the structure, under the condition that the tooth head is not damaged, the wear degree of the flat pick is maximized, and the flat pick utilization rate is maximized, so that the novel flat pick has the effects of novel structure, scientific design and strong practicality. Therefore, not only is a tooth base protected, but also the wear resistance and the wear strength of the tooth body are further improved at the same time. The service life of the flat pick is further greatly prolonged.
Description
Technical field
the utility model belongs to drill rod field, is a kind of novel flat pick specifically.
Background technology
flat pick, be called for short cutter tooth, be widely used in mining, quarrying, hydroelectric project, build the road, the engineering construction fields such as smelting, in use, due to the complicated variation of construction environment, soil body alloy body heavy wear in work progress, there is the too early obscission of alloy body, can not effectively protect tooth head, cause the excessive wear of tooth head, even cutter tooth integral body is scrapped, simultaneously in the situation that tooth head weares and teares, as easy to wear to toothholder in changed not in time pick, thereby make to produce gap between tooth handle and toothholder, tooth handle is easily deviate from toothholder and is caused can not normally use or scrap the heavy wear of toothholder.
Summary of the invention
the purpose of this utility model is to provide a kind of structural performance reasonable, and tooth head is wear-resistant, adapts to construction environment extensive, the novel flat pick that working life is longer.
the utility model is achieved in that
tooth head is designed to the flat body shape of eave tile, and this shape can effectively reduce the frictional resistance of the soil body to tooth head in work progress, avoids the whole stressed excessive deformation of flat pick body; On tooth head, the cemented carbide body of soldering is selected wedge shape conical surface body shape, strengthens its anti-wear performance and cutting power, strengthens the protection to tooth head; At tooth head-tail, offer water hole groove, by filling water column, improve better the soil body environment in work progress, effectively protect alloy body and tooth head simultaneously; In the keyway groove of offering on tooth handle, inlay respectively rubber and plastic cement key-separation, avoid producing gap between handle of a knife and tool rest and come off too early.
the utility model adopts after said structure, in the situation that guaranteeing that tooth head is not damaged, its degree of wear is maximized, and flat pick utilization rate maximizes, and has novel structure, design science, practical effect.Both be conducive to protect toothholder, and also improved anti-wear performance and the scuff resistance of cutter tooth body simultaneously, flat pick is greatly enhanced application life.
Accompanying drawing explanation
fig. 1 is front view of the present utility model, and Fig. 2 is left view of the present utility model.
in accompanying drawing 1 is tooth head, the 2nd, and tooth handle, the 3rd, alloy body, the 4th, water hole groove, the 5th, cylindrical side keyway, the 6th, figure of eight keyway, the 7th, plastic rubber key,
the 8th, plastic rubber retaining pin.
The specific embodiment
below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated:
as shown in drawings, the utility model is novel flat pick, mainly comprises flat pick body and cemented carbide body 3, and flat pick body is comprised of tooth head 1, tooth handle 2, and alloy body 3 is welded on the alloy groove on tooth head 1 top.In the front of tooth handle 2, be provided with figure of eight edge keyway 6, sidewall is provided with cylindrical key groove 5, in " 8 " shape keyway, studs with figure of eight rubber key 7, inlays cylinder plastic cement retaining pin 8 in cylindrical side keyway.
while installing and using, flat pick packs in toothholder by tooth handle, the figure of eight rubber key arranging on tooth handle and cylinder plastic cement retaining pin are firmly fixed in toothholder by cutter tooth, the cemented carbide body of tooth head and top welding excavates the soil body, the water hole groove that tooth tail end is offered simultaneously carries out water filling to construction soil body face, effectively improve working environment, reduce difficulty of construction, can avoid cemented carbide body to wear and tear and cause coming off too early because of excess, it is extensive that this uses novel flat pick to adapt to geological conditions, efficiency of construction is high, cutter tooth longer service life.
