[0002] Timber processing uses timber as raw material and is mainly carried out by mechanical or chemical methods. Its products still retain the basic characteristics of timber. In the forestry industry, timber processing and forest chemical processing are both downstream industries of forest harvesting and transportation, and are important sectors for the comprehensive utilization of timber resources. During the timber processing process, wood chips are generated, so wood chip treatment equipment is needed.

[0003] Currently, the common method for treating wood chips is to compress them. However, wood processing easily produces a large number of large chips that cannot be crushed. Direct compression will reduce the compression quality and make the compressed chips loose and inconvenient to remove after compression. Therefore, a wood chip processing device with a dustproof structure is proposed to solve the above-mentioned technical problems. Utility Model Content

It has the advantages of being able to crush large chips and making them easy to remove after compression. This solves the problem that the common wood chip processing method usually involves compression, but wood processing easily produces a large number of large chips that cannot be crushed. Direct compression will reduce the compression quality and make the compressed chips loose and inconvenient to remove after compression.

[0005] To achieve the aforementioned goal of crushing and compressing large wood chips for easy removal, this utility model provides the following technical solution: A wood chip processing device with a dustproof structure, comprising a movable base, a processing box on the top of the movable base, a compression box located to the right of the processing box on the top of the movable base, an inclined discharge plate on the inner wall of the processing box, a dust collection assembly fixedly connected to the bottom of the inclined discharge plate on the inner wall of the processing box, a dust collection pipe fixedly connected at one end to the inner top wall of the processing box on the left side of the inner wall of the processing box, and a pushing assembly on the inner bottom wall of the compression box.

[0014] 1. This dustproof wood chip processing device, equipped with a servo motor, allows wood chips to be fed into the processing chamber through the feed hopper. The servo motor then drives the left rotating shaft via its output shaft. Through the engagement of two gears, the two rotating shafts drive two crushing rollers to crush the wood chips. The crushed wood chips fall into the compression chamber through an inclined discharge plate, thus achieving the purpose of crushing large chips and preventing any impact on compression quality.

[0025] In summary, this wood chip processing device with a dustproof structure, by incorporating a servo motor 14, allows wood chips to be fed into the processing chamber 2 through the feed hopper.

The dustproof effect improves the practicality of the device. By setting the pushing component 7, after the debris falls into the compression box 3, the electric hydraulic push rod 8 is activated to drive the compression plate 9 to move down for compression.

This further improves the practicality of the device and solves the problem that the common wood debris treatment usually involves compression, but wood processing easily produces a large number of large pieces. These large pieces cannot be crushed, and direct compression will reduce the compression quality and make the compressed debris loose and inconvenient to remove after compression.
