[0002] A wood crusher is composed of a fixed frame, a motor, a crushing device, a fixed plate, a connecting plate, a discharge port and a feed port. It is mainly used to crush wood and is relatively common in the prior art.

[0003] Prior art includes a utility model with publication number CN206229463U, which discloses a novel wood crusher. The patent adopts a workbench, a crushing box and a first motor. The crushing box is arranged on the workbench and driven by the first motor. The upper and lower ends of the crushing box are respectively provided with a feed port and a discharge port. A conveying chain is arranged at the feed port, which is driven by a second motor and has saw teeth evenly distributed on the conveying chain. A dust suction port is arranged at the bottom of the discharge port, which is connected to a vacuum cleaner through a dust suction pipe. This solves the problem that due to the different specifications and lengths of the logs, manual conveying to the feed port of the crusher is required, which not only increases the danger level of the workers' operation, but also often causes the wood to get stuck at the feed port or fall, increasing the workload. After the wood is crushed, there is often a large amount of powder at the bottom of the discharge port, which seriously pollutes the environment.

[0004] In daily work, it is found that in the process of using the above-mentioned new type of wood crusher, there is a problem that because the feed port of the crusher is not equipped with a protective device, when personnel crush smaller wood, the crushing device cannot grasp the wood in time for crushing during the crushing process due to the small size of the wood, and then some wood will be splashed out of the feed port due to the excessive speed of the crushing equipment.
