Embodiment Construction

[0037] see Picture 1-1 , Figure 1-2 , Figure 1-3 , Figure 1-4 and Figure 1-5 , manual control valve assembly --- internal structure: Picture 1-1 The assembly relationship of the main parts shown in the dotted line is the main valve body 1 of the valve. The valve is a three-position four-way reversing valve. Its hydraulic principle is as follows: Figure 1-5 shown.

[0038] One side of the main valve body 1 and the handle 14 is provided with a right-handed sleeve 6, a cam 12, and a cover 15. The right-handed sleeve 6 is equipped with a torsion spring 3, and the handle 14 is connected with the right-handed sleeve 6. , the inner end of the right-handed sleeve 6 is equipped with elastic pins 8 and 9 adjacent to the valve core.

[0039] The cam 12 is sleeved on the right-handed sleeve 6, and the cam 12 has a symmetrical cam surface 12-1. The cam surface 12-1 can be a spiral surface, and of course other forms of surfaces can also be used. The elastic pin 9 of the right-ha...

Abstract

The invention provides a manual drive control valve and a wood splitting machine provided with the same. The manual drive control valve can solve the problems that the prior art has lots of components, a complex structure, needs to add an adjusting mechanism and the like. The technical scheme of the invention is that one side of a main valve body and a handle is provided with a turning sleeve anda cam, the cam is sleeved on the turning sleeve and is provided with symmetrical cam curved surfaces, a pin of the turning sleeve and a pin of a valve core are positioned on the cam curved surfaces of both sides of the cam, the other side of the main valve body and the handle is provided with a turning sleeve which is provided with a torsional spring, one pin is inserted into the valve core, the top end of the pin is in a strip slot, and a compression spring is arranged between the end surface of the turning sleeve and the main valve body. The manual drive control valve has the characteristics of fewer components, simplified structure, cost reduction, high mounting efficiency and the like.

Description

technical field [0001] This invention relates to cutting machines, and more particularly to hand-operated control valves in log splitters. Background technique [0002] The wood splitter in the cutting machine is a hand-operated working method. During the working process, the operator puts one end of the wood on the blade of the cutting axe, and the other end on the pressure plate at the end of the hydraulic piston. The disc travels forward to squeeze the wood, thereby splitting the wood. It can be seen from the above working process that the pressure plate may squeeze and injure the hand during the advancing process, and thus has certain danger to the operator. In order to improve safety and reduce hand injury accidents. The European standard puts forward new requirements for the control and protection of the ax blade wood splitter. The requirements stipulate that the arrangement of the hand control position should ensure that the operator's hand will not be between the ...
