Description

Technical Field

[0001] The utility model relates to a wood separation and transportation device, which uses a plurality of rollers fixed on a frame to realize the movement of short wood and the separation of impurities. The utility model belongs to the technical field of sorting and transportation machinery. Background Art

[0002] The bark re-crushing system does not have any equipment to separate and recycle the short wood for reuse. Instead, it is directly transported to the bark re-crusher for crushing, resulting in a waste of logs. In addition, if there are too many short wood in the bark, it will easily cause the bark re-crusher to be blocked and jammed, resulting in low production efficiency.

[0003] Existing technology, such as: a new type of roller conveyor, Chinese patent announcement number CN203781178U, which includes a frame, on which five roller groups are arranged in sequence, baffles are located on both sides of the five roller groups, and the baffles are fixed to the frame, wherein: the first group includes at least one jumping roller and at least two licker-in rollers; the second roller group includes at least one smooth roller; the third roller group includes at least two licker-in rollers; the fourth roller group includes at least one smooth roller; the fifth roller group includes at least one jumping roller and at least two licker-in rollers.

[0004] The main shortcomings of the existing technology:

[0005] 1) The existing technology is suitable for conveying and separating impurities of larger materials such as peeled logs. For the separation of smaller wood and impurities, such as the recovery of short wood mixed in the separated bark, the conveying and separation effect is poor and the applicability is poor.

[0006] 2) The prior art provides jumping rollers at the feed end and the discharge end to throw the piled logs up and spread them apart. For smaller wood and impurities, the jumping rollers and other rollers are basically in the same plane, and the separation effect of logs and impurities cannot be achieved. Summary of the invention

[0007] The purpose of the utility model is to provide a wood separation and conveying device, and the purpose to be achieved is to efficiently separate smaller wood and impurities.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A wood separation and conveying device comprises a frame, an adjusting roller assembly and a fixed roller assembly, wherein the adjusting roller assembly and the fixed roller assembly are mounted on the frame, and characterized in that: the adjusting roller assembly consists of a first adjusting roller assembly and a second adjusting roller assembly, the first adjusting roller assembly controls the height of a toothed roller through a first cylinder, the second adjusting roller assembly controls the height of a spiral roller through a second cylinder, and the rotation direction of the toothed roller and the spiral roller is the same as the material conveying direction; the fixed roller assembly consists of a first smooth roller, a first multi-sided roller, a second smooth roller, a third smooth roller, a fourth smooth roller and a second multi-sided roller, the rotation directions of the first smooth roller, the second smooth roller, the third smooth roller and the fourth smooth roller are the same as the material conveying direction, and the rotation directions of the first multi-sided roller and the second multi-sided roller are opposite to the material conveying direction.

[0010] As an improvement of the utility model, the first adjusting roller assembly is further provided with a swing arm and a first arc-shaped groove, the first cylinder is connected to the gear roller through the swing arm, and the two ends of the gear roller are installed in the first arc-shaped groove.

[0011] As an improvement of the utility model, the second adjusting roller assembly is further provided with a connecting arm and a second arc groove, the second cylinder is connected to the second arc groove via the connecting arm, and both ends of the spiral roller are installed in the second arc groove.

[0012] As an improvement of the utility model, a second reduction motor is provided at one end of the spiral roller, and the other end of the spiral roller is connected to the first smooth roller via a pulley or a sprocket.

[0013] As an improvement of the utility model, a fourth reduction motor is provided at one end of the third smooth roller, and the other end of the third smooth roller is respectively connected to the second smooth roller and the fourth smooth roller through a pulley or a sprocket.

[0014] As an improvement of the present utility model, the inclination angle of the fixed roller assembly is α, 16°≤α≤36°.

[0015] As an improvement of the utility model, a bark outlet is provided below the adjusting roller assembly and the fixed roller assembly, and a short wood outlet is provided at the tail of the fixed roller assembly.

[0016] Beneficial effects after adopting the above technical solution:

[0017] 1) Setting the rotation direction of the adjusting roller assembly and the fixed roller assembly not only effectively adjusts the height between the conveyed material and the fixed roller assembly, but also controls the conveying speed of the material, so that the mixture of bark and short wood is evenly distributed, and a large amount of bark materials can be separated.

[0018] 2) The use of two specific adjusting roller assemblies can better control the height between the conveyed material and the fixed roller assembly, adapt to the separation of short wood and bark of different specifications and sizes, and improve the separation effect.

[0019] 3) Specific fixed rollers are connected by pulleys or sprockets to effectively realize the forward or reverse rotation of the specific fixed rollers. The structure is simple and the control is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
