Firewood splitting machine

Abstract

The invention discloses a firewood splitting machine and belongs to the technical field of firewood sheet splitting tools. The firewood splitting machine comprises an underframe, a hydraulic jack which is arranged on the underframe and is provided with a cylinder column, an oil pump and an oil return valve, a stand column which is arranged on the underframe, a tool rest which is arranged on the stand column and is provided with an axe, and a table board frame which is arranged on the stand column, is positioned below the tool rest and is provided with a table board pushed by the cylinder column, wherein an oil pump operating pedal which is connected with the oil pump is hinged to the underframe. The firewood splitting machine is characterized in that: a cylinder column base cavity is formed on one side of the table board, which is opposite to the cylinder column, and is positioned at an intersection point of diagonal lines of the table board; the cylinder column is matched with the cylinder column base cavity; one end of a tension spring is connected to the center of each of the left side and the right side of the table board; and the other end of the tension spring is fixed on the underframe. The firewood splitting machine has the advantages that: a stress point of the table board is reasonable, and phenomena that the connection part of the table board and the table board frame is broken and the table board frame and the stand column are meshed are avoided.

Description

technical field [0001] The invention belongs to the technical field of firewood splitting tools, and in particular relates to a firewood splitter, which is used for splitting large-sized firewood segments into firewood flaps that can be used for burning. Background technique [0002] The introduction of technical solutions such as "a firewood splitter" (notification number: CN201559240U) and "firewood splitter" (notification number: CN2313727Y) disclosed by Chinese patent documents can substantially improve the traditional way of splitting firewood. Change. The so-called traditional ways of chopping wood mainly include the following: one is to use tools such as axes to chop and chop, which is inefficient and labor-intensive; the other is to manually saw the firewood with a saw. There are the shortcomings of low efficiency and high labor intensity; the third is to split by means of machines. Although this method can avoid the aforementioned shortcomings of manual chopping, d...

Problems solved by technology

[0005] However, the "wood splitter" released by the above-mentioned CN2496619Y has the following technical problems: the table top 51 is easily broken by the rising or falling oil cylinder column 21, because it is installed on the chassis 1 There is at least a distance of 1 / 2 of the outer diameter of the hydraulic jack 2 between the hydraulic jack 2 on the top and the bottom of the column 3, so the oil cylinder column 21 of the hydraulic jack 2 can only be connected with the end of the table top 51 away from the table frame 5. Hardwired in the center

Therefore when the oil cylinder column 21 extends outwards from the cylinder body of the hydraulic jack 2 to push the table top 51 and rises along the column 3 together with the table frame 5, since the action point of the oil cylinder column 21 is not at the intersection of the diagonals of the rectangular table top 51 Therefore, the force is extremely uneven, which may easily lead to deformation of the joint between the table top 51 and the table frame 5

Conversely, when the oil cylinder column 21 is reset and retracted into the cylinder body of the hydraulic jack 2, the above-mentioned situation also exists, so it does not take long for the junction between the table top 51 and the table frame 5 to break

And because the action point of the oil cylinder column 21 is not at the intersection of the diagonal lines of the table top 51, the effect of the table frame 5 sliding up and down along the column 3 is seriously affected, and even the table frame 5 may be bitten between the column 3 (gnawing to death) phenomenon, it is difficult for the countertop frame 5 to slide freely on the column 3
