Abstract
The invention discloses a chain saw guide board which comprises two lateral boards and a core board which is connected between the middle of the two lateral boards. A guide board groove which is used for jogging the chain is formed between the core board and the two lateral boards. A liquid channel system is arranged between the lateral boards and the core board. Lateral walls of the lateral boards are provided with liquid inletting holes which are communicated with the liquid channel system. The liquid channel system is provided with a plurality of liquid spraying holes opening into the guide board groove. The liquid channel system comprises a drainage main channel, drainage furca channels and a drainage branch channel. Two liquid inletting holes are respectively arranged on the upper part and the lower part on one side of the tail part of the two lateral boards. The two liquid inletting holes are communicated with the drainage main channel respectively by the two drainage furca channels. The liquid channel system is formed by using the two lateral boards to seal the grooves opened on the lateral walls of the core board. With the chain saw guide board adopted, liquid can flow into the liquid channel system in the guide board from the liquid inletting holes and be sprayed to the two lateral sides of the guide board by the guide board groove and the guide board groove and a guide wheel at the front end for cooling, cleaning and lubricating the chain, the guide board groove and the guide wheel.
Description
Technical field
The present invention relates to chain saw, relate in particular to the guide plate of chain saw.
Background technology
General chain saw mainly is provided with engine portion and can be locked in the guide plate of engine portion, the patent No. is that the chain saw guide plate of the Chinese utility model patent of ZL200720000138.7 is repeatedly combined mutually by three lengthy motion picture shape metallic plates, wherein the configuration of two lamina rara externas and size can be corresponding mutually, and the clamping plate clamping that configuration is less therebetween, the thickness that has according to clamping plate itself, use the chimeric saw chain bar of cutting the saw function that has and can form the guide plate groove in the periphery between crossover two lamina rara externas, make the tooth of leading of saw chain bar can be along the guiding of this guide channel and reciprocating operation, and carry out the cutting of object.Thereby, but guide plate is for support chains and makes the important component of chain smooth operation.At present the chain saw guide plate that uses is solid mostly, though what have is hollow, hollow parts is obstructed mutually, does not also lead to the outside, and its hollow purpose is weight reduction.At present the guide plate lubricating oil that uses is that oilhole from guide plate body afterbody enters the guide plate groove, takes each lubricated face to by saw chain then.This lubricating system, lubricating oil major part are got rid of by saw chain or just trickle near the guide plate fuel feed hole, and the lubricating oil utilization ratio is very low, and cleaning and cooling effect are also very weak.Need the powerful occasion of cleaning, cooling off and lubricating for some, during as sawing concrete, brick, stone, this guide plate just can not use at all.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of chain saw guide plate, can improve the lubricating oil service efficiency, and saw chain, guide plate groove and directive wheel are efficiently cooled off, clean and lubricate.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of chain saw guide plate, comprise two blocks of side plates and be connected the middle central layer of biside plate, form the guide plate groove of using in order to chimeric saw chain between described central layer and biside plate, it is characterized in that: be provided with the fluid passage system between described side plate and central layer, the sidewall of described side plate offers the inlet opening with the fluid passage system connectivity, offers the spray hole that several lead to the guide plate groove in the described fluid passage system.
As improvement, described inlet opening is located at the sidewall of side plate afterbody, and inlet opening is communicated with drain main stem one end in the fluid passage system, and the drain main stem connects the guide plate front-end and back-end, and the spray hole opening of its other end is located in the guide plate front end guide plate groove.Be convenient to feed liquor and fluid.
As preferably, described inlet opening is established two, opens respectively in the upper and lower of the afterbody one side side of biside plate, is communicated with by two drain caudal furca roads respectively between two inlet openings and drain main stem.Increase the liquid flow channel, helped the inflow of liquid.
As preferably, be provided with the drain by-path that is communicated with the drain main stem between described side plate and central layer, the end of drain by-path is located at several spray holes in the guide plate groove for opening.All flow to the guide plate groove from the liquid of drain by-path ejection and the liquid of drain main stem ejection, improved lubricated, cleaning and cooling effect.
As preferably, described drain by-path is that axis is symmetrically distributed in the guide plate with the drain main stem.The turning 180 ° of uses of guide plate so simultaneously can make liquid flow to the guide plate trench bottom uniformly.
Further, described drain main stem, drain caudal furca road, drain by-path, spray hole are formed by the groove that the biside plate sealing is opened in the central layer sidewall.Central layer can conveniently be processed various grooves before welding like this, with the fixing fluid passage system that forms of side plate welding, is convenient to processing and manufacturing then.Perhaps above-mentioned fluid passage is formed by the groove on the central layer sealing side plate madial wall.
As preferably, described guide plate front end is equipped with directive wheel.The motion of guiding chain saw.
As improvement, described spray hole perpendicular to the degree of depth of guide plate in-plane greater than 1/5th of central layer thickness, less than 2/3rds of central layer thickness, the preferred spray hole degree of depth is 1/3rd of a central layer thickness.Described drain main stem width is greater than drain by-path width, and drain by-path width is greater than the spray hole width.Make liquid can balancedly flow to the place that each needs like this.
The present invention is owing to adopted technique scheme, liquid can flow into fluid passage system in the guide plate by inlet opening, spray hole sprays near the guide plate groove and directive wheel of guide plate dual-side and front end in the guide plate groove, and saw chain, guide plate groove and directive wheel are cooled off, clean and lubricate.Because the fluid passage system is the channel system of a sealing, can not scatter and disappear after liquid enters, can all flows near guide plate groove and the directive wheel, thereby can guarantee saw chain, guide plate groove and directive wheel are carried out the brute force cooling, clean and lubricate.In this way, can alleviate the heating and the wearing and tearing of saw chain, guide plate and directive wheel, increase the service life, also can save lubricating oil.When sawing concrete, brick, stone etc. can produce the material of a large amount of powder, the big quantity of fluid that enters through the fluid passage system can wash away powder, and sawing process can normally be carried out.
