Description

The bidirectional hydraulic riving machine

Technical field

The utility model relates to the riving machine industry, especially a kind of bidirectional hydraulic riving machine.

Background technology

The riving machine kind is a lot; Riving machine manual, pneumatic, electronic, motor-driven form is arranged, be widely used in the gardens wood industry in American-European Australia, timber is a kind of organic energy of very environmental protection; These countries advocate and use the timber heating etc. of lighting a fire, so all farms and even every household all use riving machine; Riving machine is usually by power section both at home and abroad at present, and control valve is carried out several most of compositions such as oil cylinder and support; Wherein power section can be that engine and hydraulic oil pump are formed, or motor and hydraulic pump composition, or simple piston formula air pump; Also possibly be various ways such as plunger type hand oil pump, control section is according to the difference of power source or executing agency and difference is seen the common valve core type rotary valve that has from structure; The disc type rotary valve, valve core type guiding valves etc. have been seen two-position three-way valve from function; Or three-position four-way valve etc., these various valves all can satisfy the requirement of riving machine on function; Carrying out oil cylinder is the single-acting or the double-act-ing hydraulic J-Horner of single-stage mostly, sees once in a while to have for the length that shortens riving machine and adopts double-acting twin-stage oil cylinder.

Splitting when adopting oil cylinder piston to push out during the wood machine operation mostly, and the return of piston-retraction is backlash.Existing market also has a kind of two-way riving machine; And also can splitting in the piston two-way process; But its complex structure, manufacturing cost is high, installs and keep in repair very inconvenient; Also having a very big deficiency is exactly that whole riving machine structure bearing capacity receives serious limitation, and cylinder block and riving machine fuselage are easy to distortion and are worn.

The utility model content

The purpose of the utility model is to provide for the deficiency that solves above-mentioned technology that a kind of simple in structure, easy to maintenance, bearing capacity is strong, the bidirectional hydraulic riving machine of low cost of manufacture.

In order to achieve the above object, a kind of bidirectional hydraulic riving machine that the utility model designed, it mainly comprises oil cylinder, fuselage, frame, actuating unit and control valve; Actuating unit is set on the frame, control valve and oil cylinder are set on the fuselage, be provided with support at fuselage bottom; Be set with axe on the termination of the cylinder body of described oil cylinder, cylinder interior is provided with piston rod, and piston rod is a hollow structure; In this hollow structure, be provided with internal oil passages, an end of internal oil passages is connected with control valve, and the other end of internal oil passages leads to oil cylinder A chamber; Piston rod two is provided with the first oil circuit hole and the second oil circuit hole; The first oil circuit hole is connected with control valve, and the second oil circuit hole leads to oil cylinder B chamber, and described frame directly is made up of fuel tank.This simple and compact for structure, do not need very long internal oil passages, fuel tank reaches the effect of promptly playing support as frame and has practiced thrift cost again.

Installation and dismounting for the ease of axe; And the wood fragments bits can drop timely in the process of using, and described fuselage two ends are provided with baffle plate A and baffle plate B, wherein have on the baffle plate B one can the fuel feeding cylinder on the notch that passes of axe; Be provided with installing plate through screw on the fuselage of baffle plate B both sides; Installing plate is connected with the bar head of piston rod, and the centre position on the fuselage is provided with elongated slot, is provided with several reject chutes below the fuselage.

For better convenient for maintaining, described oil cylinder A chamber is provided with end cap, and wherein end cap is to install and fix through elastic spring shrouding and screw.This structure both can be taken out oil cylinder piston through unclamping screw decomposition elastic spring and end cap, made things convenient for the maintenance of oil cylinder piston and the replacing of seal.

The resulting a kind of bidirectional hydraulic riving machine of the utility model pumps hydraulic oil through control valve and internal oil passages entering oil cylinder A chamber from fuel tank through actuating unit, makes cylinder block realize the left-hand splitting in axe operation left together; When the control valve switching-over is in reverse position, hydraulic oil is pumped through control valve and oil circuit hole entering oil cylinder B chamber from fuel tank equally, make cylinder block realize reverse splitting in axe operation to the right together through actuating unit.This structure does not need very long internal oil passages, and is simple and compact for structure; Oil cylinder and fuselage receive tension and compression and bending stress simultaneously, and the effect of all carrying is fine, and bearing capacity is strong; Simultaneously as long as unclamp the screw of oil cylinder installing plate and fuselage connection, oil cylinder comprises that axe integral body just can all pull out like a cork from fuselage; Installation and removal are convenient; Simultaneously can through unclamp screw decompose elastic spring and end cap promptly can with the oil cylinder inner carrier take out carry out seal replacing in maintenance, and need not decompose oil cylinder and fuselage, so easy to maintenance.
