Description

Technical Field

[0001] The utility model relates to the field of wood processing, in particular to a wood raw material crusher. Background Art

[0002] Wood raw material crusher, also known as log crusher, is a new type of wood powder production machinery and equipment. It can process wood, branches and other raw materials into wood chips at one time. It has the advantages of low investment, low energy consumption, high productivity, good economic benefits, and easy use and maintenance.

[0003] The wood crusher is mainly composed of a body, a crushing disc and a filter screen. The crushing disc adopts an alloy cutter head, which is driven by a motor to follow the high-speed rotation of the disc, so that the machine can generate high-speed airflow to produce high-intensity impact force, compression force and cutting force on the crushed materials, and achieve a unique crushing function. A small household wood crusher is provided with two sets of feed ports. Two sets of different cutters are installed inside the crusher. One set of disc cutters is suitable for crushing some slender cylindrical wood, and the other set of fan-shaped cutters is suitable for crushing branches.

[0004] However, when the crusher is in use, it is difficult to crush some larger wood piles. The disc cutter can also crush thick wood piles, but thick wood piles are generally large in diameter and short in length. When the thick wood piles are put into the corresponding disc cutter's feed port, for safety reasons, workers will not continue to push the thick wood piles inward, which makes the disc cutter spend more time cutting the end face of the thick wood pile than the end face of a slender log, and the workers will not apply external force to push the thick wood piles, which leads to a slow feeding speed of the thick wood piles when the disc cutter crushes the thick wood piles. At the same time, because the wood piles are thicker, the inside is not easily dried, which makes the wood piles more resilient and more difficult to cut than dried wood. The disc cutter will also damage the cutter if it crushes large-diameter thick wood piles multiple times. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a wood raw material crusher to solve the technical problems mentioned in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wood raw material crusher comprises a bottom bin, an upper cover and a bracket, the bottom bin is rotatably connected to a rotating shaft inside, and one end of the rotating shaft is connected to a driving assembly, a turntable and a branch cutter are installed outside the rotating shaft, and a fine log cutter is installed on the side of the turntable, a coarse wood pile feeding port is provided on the side of the bottom bin, and a wood pile cutter is installed inside the coarse wood pile feeding port, a strip groove is provided on one side of the coarse wood pile feeding port, a push rod is movably installed, and a linkage ring is provided at one end of the push rod, a transmission assembly is installed on the top of the bracket, and a linkage rod is installed on the side of the transmission assembly, and the linkage rod is engaged with the inside of the linkage ring, an electromagnetic clutch is installed on the side of the bottom bin, and the input end of the electromagnetic clutch is connected to the rotating shaft, and the output end of the electromagnetic clutch and the transmission assembly are connected by a worm gear reducer.

[0009] By adopting the above technical solution, by setting up multiple groups of branch cutters, soft and messy branches can be better crushed, and wood chips cut by thin log cutters can also be crushed.

[0010] The utility model is further configured that a thin log feeding port is arranged on the side of the bottom bin, a feeding port is arranged on the side of the bottom bin, and a branch feeding port is arranged on the side of the upper cover.

[0011] By adopting the above technical scheme, a thin log feeding port is provided to feed thin logs, a discharge port is provided to discharge wood chips, and a branch feeding port is provided to feed soft branches.

[0012] The utility model is further configured that one end of the bottom bin and the upper cover are rotatably connected, and the other ends of the bottom bin and the upper cover are fixed by bolts, so that the upper cover can be opened.

[0013] By adopting the above technical solution and arranging a rotational connection between the bottom bin and the upper cover, the upper cover can be opened, thereby facilitating later maintenance of the interior.

[0014] The utility model is further configured that a screening cylinder is installed inside the bottom bin and the upper cover, a plurality of screening holes are evenly distributed outside the screening cylinder, and the screening cylinder is formed by splicing two semicircular arcs.

[0015] By adopting the above technical solution, the size of the wood chips can be filtered by setting a screening cylinder, and the wood chips that do not meet the size can continue to be crushed.

[0016] The utility model is further configured that the drive assembly is fixedly installed on the top of the bracket using bolts.

[0017] By adopting the above technical solution, the rotating shaft can be driven to rotate by arranging a driving component installed on the top of the bracket.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] The utility model can divide a thick wood pile into multiple parts by arranging a wood pile cutter, and the wood obtained after the division has a smaller diameter, so that the fine log cutter is more efficient in cutting and crushing the divided wood pile, and the cutting speed is improved while reducing the risk of damaging the fine log cutter. The rotating shaft of the crusher is used to drive the transmission component to rotate through the worm gear reducer, and the transmission component drives the push rod to reciprocate, and then when the push rod is away from the wood pile cutter, the thick wood pile is put in, and when the push rod is reset, it pushes the thick wood pile to be squeezed toward the wood pile cutter, so that the wood pile is divided into multiple wood materials with small diameters when it enters the bottom bin.
