Abstract
The invention relates to the technical field of forestry mechanical equipment, in particular to an automatic pre-tightening chain saw guide plate with a replaceable head. The automatic pre-tightening chain saw guide plate with the replaceable head comprises a guide plate body, a guide plate head and an automatic pre-tightening leaf spring, wherein guide plate chain troughs are respectively arranged on the guide plate body, the guide plate head and the automatic pre-tightening leaf spring, the front end of the guide plate body is provided with a guiding positioning gap, the automatic pre-tightening leaf spring is provided with a through hole, and the guide plate head penetrates through the through hole and is inserted into the guiding positioning gap. The automatic pre-tightening chain saw guide plate with the replaceable head disclosed by the invention is convenient to operate, and has a simple structure and long service life.
Description
Technical field
The present invention relates to the forestry machinery equipment technical field, the replaceable automatic pretension chain saw guide plate of specifically a kind of head.
Background technology
The gasoline saw that is used for industries such as forest lumbering, producing material and decoration on the existing market wherein directly influences the service life that gasoline is sawed the service life of chain saw guide plate.Existing chain saw guide plate is generally monoblock type, though it is simple in structure, and low cost of manufacture, its nose section load is heavy, and wearing and tearing are big, are prone to break, in case damage, need integral replacing, make its use cost higher; In addition, guide plate self to the pre-tightening apparatus of saw chain, does not use for a long time, and saw chain is prone to lax, needs to carry out manual pretension to saw chain and operates, and uses inconvenience.
Summary of the invention
The present invention provides a kind of head easy to operate, simple in structure, long service life replaceable automatic pretension chain saw guide plate.
The present invention realizes through following technical proposals:
The replaceable automatic pretension chain saw guide plate of a kind of head; Comprise guide plate body, nose and automatic pretension leaf spring; Be equipped with the guide plate key way on said guide plate body, nose and the automatic pretension leaf spring; Said guide plate body front end is provided with the guide-localization breach, and said automatic pretension leaf spring is provided with through hole, and said nose passes said through hole and inserts said guide-localization breach.
Said nose is " T " shape, comprises spheroidal head and cuboid afterbody, and said through hole and said guide-localization indentations section are rectangle, and the cross section of said cuboid afterbody and said through hole and said guide-localization indentations section are complementary.
The beneficial effect that the present invention brought is:
Among the present invention; The replaceable automatic pretension chain saw guide plate of said head comprises guide plate body, nose and automatic pretension leaf spring, and said nose can be selected high-abrasive material for use, and the guide plate body can adopt common material; Nose and guide plate body structure are simpler, and the manufacturing cost of whole guide plate is not high; Secondly, according to the automatic pretension leaf spring that the required pretightning force of saw chain designs, the pretightning force of saw chain is in use remained in certain scope; Do not need manual adjustment; Easy to use, simultaneously, when chain saw contacted with hard cutting object moment; Said automatic pretension leaf spring can play certain cushioning effect, and stability and security when guide plate is used are improved; In addition, said guide plate is in long-term the use, if nose wearing and tearing or break, only needs to change nose and need not change whole guide plate, and the use cost of chain saw guide plate is reduced.
