Firewood chopping mechanism

Abstract

The invention relates to a firewood chopping mechanism, and belongs to the technical field of firewood chopping tools. The firewood chopping mechanism comprises a base frame, a hydraulic jack with an oil cylinder column, an oil pump and an oil return valve, a column, a tool holder with an ax, and a table-board rack with a table board, wherein the table-board rack is positioned below the tool holder, and an oil pump control pedal is hinged onto the base frame. The firewood chopping mechanism is characterized in that: an oil cylinder column seat cavity is arranged at one side of the table board toward the oil cylinder column, and is positioned at an intersection of diagonals of the table board, the middles of the left and right sides of the table board are respectively connected with one end of a tension spring, and the other end of the tension spring is fixed on the base frame; a liquid return valve actuator pedal is hinged on the base frame, and a protective mechanism consisting of a stop lever seat and a pair of stop levers is fixedly arranged on the table-board rack; and the stop lever seat is fixed on the table-board rack, one of the pair of stop levers is fixed at one side of the stop lever seat, and the other stop lever is fixed at the other side of the stop lever seat. The firewood chopping mechanism has the advantages that: the force-bearing points are reasonable, the convenience in operation is reflected, and the working efficiency is improved; and the use is convenient.

Description

technical field [0001] The invention belongs to the technical field of firewood splitting tools, and in particular relates to a firewood splitting mechanism, which is used for splitting large-sized firewood into firewood. 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, due to the need to send the firewo...

Problems solved by technology

[0005] But, there are following technical problems in the "firewood splitter" released by the above-mentioned CN2496619Y: one, the table top 51 is easily broken by the rising or falling oil cylinder column 21, because it is installed on There is at least 1 / 2 the distance of the outer diameter of the hydraulic jack 2 between the hydraulic jack 2 on the chassis 1 and the bottom of the column 3, so the cylinder column 21 of the hydraulic jack 2 can only be connected to the table top 51 away from the table frame 5 The center position connection of one end of the

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

Second, the operation of draining oil is inconvenient and affects the working efficiency. From the structure of this patent, it can be seen that after each firewood chopping action is completed, the firewood billet between the table top 51 and the ax 41 is split after the oil cylinder column 21 rises to the right position. , the recovery of the oil cylinder column 21 needs to be turned by the operator's waist to turn the oil return valve on the hydraulic jack 2; thirdly, a chain is used as a protective device to prevent the firewood from splashing out. Although it has the advantages of simple structure, the chain's Inconvenient to use
