Description

Technical Field

[0001] This utility model relates to the field of wood processing, and more specifically, to a log conveying and sorting device. Background Technology

[0002] Wood is the lignified tissue formed by plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rhizome becomes active, developing phloem outwards and wood inwards.

[0003] When processing timber, lumberyards often process the timber into round logs. The processed logs are then stored and arranged in an orderly manner according to their size for later use. At this point, the processed logs need to be transported and sorted. Traditionally, sorting can only be done manually. Logs coming out of the processing workshop can only be forked out and stored separately by forklifts and other machinery, which is inefficient and inconvenient.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0026] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0027] Please see Figure 1-9 According to an embodiment of the present invention, a log conveying and sorting device includes a base plate 1. A frame 2 is fixedly installed on the top of the base plate 1. A sorting mechanism 3 is fixedly installed on the top of the frame 2. A conveying mechanism 4 is fixedly installed at one end of the top of the frame 2. The top of the conveying mechanism 4 and the top of the sorting mechanism 3 are coplanar. A material distribution assembly 7 is also installed inside the frame 2. The material distribution assembly 7 is located directly below the sorting mechanism 3, and there are two sets of material distribution assemblies 7. The two sets of material distribution assemblies 7 are symmetrically arranged along the length centerline of the frame 2. The tops of the two sets of material distribution assemblies 7 penetrate through the middle of the sorting mechanism 3. Universal wheels 5 are also installed at the four corners of the bottom of the base plate 1, and brake components 6 are installed on the sides of the universal wheels 5. Logs are conveyed to the sorting mechanism 3 by the conveying mechanism 4, and then the logs are sorted to both sides of the sorting mechanism 3 by the two sets of material distribution assemblies 7. The sorted logs can be collected separately by setting receiving devices on both sides of the frame 2.

[0028] To enable the sorting mechanism 3 to effectively support and position the logs conveyed from the conveying mechanism 4, in this embodiment, the sorting mechanism 3 includes a fixed frame 8, which is fixedly installed on the top of the frame 2 and is arranged along the length of the frame 2. A strip frame 9, arranged along its length, is fixedly installed at the top center of the fixed frame 8. A guide roller 10 is rotatably installed inside the strip frame 9. One end of the guide roller 10 extends out of the strip frame 9 and is fixedly installed with a transmission sprocket 11. Adjacent transmission sprockets 11 are connected by a first chain 12. The logs conveyed by the conveying mechanism 4 can move along the arrangement direction of the guide rollers 10 installed inside the strip frame 9, thereby supporting the logs. Subsequently, the sorting and adjustment can be achieved by the material distribution assembly 7.

[0029] In order to enable the material sorting component 7 to sort the logs on the guide rollers 10, in this embodiment, the material sorting component 7 includes an L-shaped plate 15. The top end of the L-shaped plate 15 is located between two adjacent guide rollers 10. The bottom ends of the L-shaped plate 15 are fixedly connected by a first connecting shaft 16. The corners of the L-shaped plate 15 are fixedly connected by a second connecting shaft 18. A groove plate 22 is fixedly installed inside the frame 2. The two ends of the first connecting shaft 16 are rotatably installed on the groove plate 22 through a first bearing seat 17. An extension seat 19 is fixedly installed at the bottom inside the frame 2. A first hinge seat 20 is fixedly installed at the top of the extension seat 19. A first cylinder 21 is hingedly installed at the top of the first hinge seat 20. The output shaft end of the first cylinder 21 is rotatably connected to the middle of the second connecting shaft 18. When the first cylinder 21 is activated, the output shaft of the first cylinder 21 can drive the L-shaped plate 15 to rotate around the first connecting shaft 16 via the second connecting shaft 18. At this time, the top end of the L-shaped plate 15 will protrude from the top of the guide roller 10, thereby lifting the logs on the guide roller 10. Since the two batching components 7 are symmetrically arranged, the L-shaped plates 15 in the two batching components 7 lift the logs in opposite directions, thus lifting the logs on the guide roller 10 in different directions and causing them to fall in different directions, thereby achieving the sorting operation.

[0030] To ensure greater stability when the logs fall from the guide roller 10, in this embodiment, a feeding assembly 34 is installed at the bottom of both sides of the fixed frame 8 along its length direction. A guide plate 13 is also fixedly installed on both sides of the top of the strip frame 9 along its length direction. The guide plate 13 is inclined and its bottom is fixedly connected to the fixed frame 8 via a support rod 14. The feeding assembly 34 includes a feeding plate 35 and a strip plate 36. The strip plate 36 is fixedly installed on the outer wall of the fixed frame 8. Second bearing seats 37 are fixedly installed at both ends of the side of the strip plate 36 facing the feeding plate 35. An assembly shaft 38 is rotatably installed between the second bearing seats 37 and is fixedly connected to the feeding plate 35. A third hinge seat 40 is also fixedly installed on the top of the base plate 1 on both sides of the frame 2. A diagonal brace 39 is installed on the top of the third hinge seat 40. An insertion hole 41 is opened on the side of the feeding plate 35 facing the frame 2. By utilizing the space between the diagonal brace 39 and the insertion hole 41 on the feeding plate 35, the feeding plate 35 can be tilted. When the logs fall from the guide roller 10, they can first fall along the guide plate 13 onto the feeding plate 35, and then fall from the feeding plate 35 to the predetermined position, thus achieving sorting and receiving.

[0031] To ensure controllable obstruction of logs entering the guide roller 10 and prevent logs from being transferred from the conveying mechanism 4 to the sorting mechanism 3 before the logs on the guide roller 10 have been sorted, in this embodiment, a second hinge seat 23 is fixedly installed at the bottom of the frame 2 near the conveying mechanism 4. A second cylinder 24 is hinged to the top of the second hinge seat 23, and a limit rod 25 is fixedly installed at the end of the output shaft of the second cylinder 24. A guide sleeve 26 is fixedly installed inside the fixed frame 8 near the conveying mechanism 4, and the limit rod 25 passes through the guide sleeve 26. The second cylinder 24 can drive the limit rod 25 to pass through the strip frame 9, thereby obstructing the conveying of logs at the top of the guide roller 10, preventing logs on the conveying mechanism 4 from entering the area above the material distribution component 7, and avoiding mutual interference between logs.

[0032] In order to enable the conveying mechanism 4 to effectively convey the logs to be sorted, in this embodiment, the conveying mechanism 4 includes a fixed frame 27, which is fixedly installed on the top of the frame 2. A motor 28 is fixedly installed on one side of the fixed frame 27. A drive sprocket 29 is fixedly installed at the end of the output shaft of the motor 28. A conveying roller 30 is rotatably installed on the top of the fixed frame 27. A driven sprocket 31 is fixedly installed at one end of the conveying roller 30. Two adjacent driven sprockets 31 are also connected by a first chain 12. The driven sprocket 31 near the motor 28 is connected to the drive sprocket 29 by a second chain 32. The driven sprocket 31 near the guide roller 10 is connected to the nearby transmission sprocket 11 by the first chain 12. An auxiliary roller 33 is also installed on the side of the top of the fixed frame 27 away from the fixed frame 8. The auxiliary roller 33, the conveying roller 30 and the guide roller 10 are all concave rollers of the same shape.

[0033] Through the above-described solution of this utility model, the structure of this utility model is simple. The sorting mechanism 3 can lift the round logs on the guide roller 10 by adjusting the L-shaped plate 15. The lifted round logs can then slide to both sides of the sorting mechanism 3 via the guide plate 13. With the help of the unloading plate 35, the round logs can be transported to the appropriate area. Moreover, the unloading plate 35 can be folded and stored outside the fixed frame 8, so it does not occupy external space when not in use. Furthermore, the tilt angle of the unloading plate 35 can be adjusted by the diagonal brace 39 and the insertion hole 41. At the same time, the limiting rod 25 can also prevent the round logs in front and behind from interfering with each other.
