Description

Technical Field

[0001] This utility model belongs to the field of wood chip collection technology, specifically relating to a wood chip collection device for wood processing. Background Technology

[0002] Wood processing, which uses wood as raw material, is mainly carried out using mechanical or chemical methods. The products retain the basic characteristics of wood. Mechanical methods are generally used more in wood processing. With the continuous advancement of technology, people have gradually replaced manual labor with automated machinery to process wood. However, a large amount of wood chips are generated during the wood processing process. To facilitate subsequent use, the wood chips are transported and collected to designated locations for later use.

[0003] Existing wood chip collection devices for wood processing mostly employ a fixed installation design, resulting in an inability to dynamically adjust the working angle between the conveyor frame and the base frame according to actual working conditions. When facing workstations with wood chip accumulation at different heights, the lack of a stepless adjustment mechanism or limited adjustment range necessitates operators to change the device's posture through discrete adjustments such as adding or removing shims and disassembling support components. This not only suffers from low adjustment accuracy and time-consuming processes but also severely impacts operational continuity in continuous processing scenarios due to frequent shutdowns for adjustments. This has become a key technical bottleneck restricting the adaptability and production efficiency of wood chip collection systems. Therefore, a wood chip collection device for wood processing is needed to help solve this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a wood chip collection device for wood processing. This wood chip collection device uses the hinge point between the base frame and the conveyor frame as a fulcrum to adjust the tilt angle of the conveyor frame. The stepless adjustment of the conveyor frame angle is achieved through the linkage of the lead screw and the support rod, adapting to wood chip collection scenarios with different height requirements and improving the applicability of the device.

[0024] A base frame 10 is installed at the bottom of the aforementioned conveyor frame 1. One end of the base frame 10 is hinged to the bottom of one end of the conveyor frame 1. An adjustment cavity is opened at the other end of the base frame 10. A support assembly 12 for adjusting the angle of the conveyor frame 1 is installed in the adjustment cavity. The support assembly 12 includes a lead screw 14 rotatably disposed in the adjustment cavity. A sliding block 15 is sleeved on the lead screw 14. The lead screw 14 and the sliding block 15 are threaded together. A support rod 16 is inclinedly hinged between the conveyor frame 1 and the sliding block 15. A servo motor 13 for rotating the lead screw 14 is installed on the base frame 10.

[0025] Through the cooperation between the base frame 10 and the support assembly 12, which are hinged at the bottom of the conveyor frame 1, the servo motor 13 drives the lead screw 14 to rotate, which in turn drives the sliding block 15 to move along the axial direction of the lead screw 14. The sliding block 15 pushes or pulls the conveyor frame 1 through the support rod 16. With the hinge point between the base frame 10 and the conveyor frame 1 as the fulcrum, the tilt angle of the conveyor frame 1 is adjusted. The stepless adjustment of the angle of the conveyor frame 1 is achieved through the linkage between the lead screw 14 and the support rod 16, which can adapt to wood chip collection scenarios with different height requirements and improve the applicability of the device.

[0026] like Figure 1 and Figure 4 As shown, a receiving groove 4 is provided at the top of the conveyor frame 1, and a top plate 2 is installed on the receiving groove 4. A feeding funnel 3 is provided at one end of the top plate 2, and a discharge port is provided at the other end of the top plate 2. A positioning hole 41 is drilled in the receiving groove 4, and a fixing groove is provided inside the positioning hole 41. A connecting hole communicating with the positioning hole 41 is provided through the top plate 2. A positioning component 5 is installed at the connecting hole and is fixed to the positioning hole 41. The positioning component 5 includes a positioning pin 51. A sliding cavity is provided inside the positioning pin 51. A sliding rod 52 is installed inside the sliding cavity. A trumpet-shaped extrusion port is provided at the bottom of the sliding cavity.

The combination design of the moving wheels 11 and the brake pads takes into account both the mobility and working stability of the device, adapting to the processing needs of multiple scenarios. When adjusting, the servo motor 13 is started, and the servo motor 13 drives the lead screw 14 to rotate, which drives the sliding block 15 to move along the axis of the lead screw 14. The sliding block 15 pushes or pulls the conveyor frame 1 through the support rod 16. With the hinge point between the base frame 10 and the conveyor frame 1 as the fulcrum, the tilt angle of the conveyor frame 1 is adjusted. The stepless adjustment of the angle of the conveyor frame 1 is achieved through the linkage of the lead screw 14 and the support rod 16, which adapts to the sawdust collection scenarios with different height requirements and improves the applicability of the device.

[0030] Wood chip collection and conveying: Wood chips enter the space enclosed by the top plate 2 and the conveyor frame 1 through the feed hopper 3. The conveyor motor 7 drives the conveyor shaft 6 to rotate, which drives the conveyor belt 8 to run. The wood chips move towards the discharge port under the action of the blocking strip 9 and are finally discharged from the discharge port to complete the collection. The continuous operation of the conveyor belt 8 realizes automated wood chip collection and conveying, reduces manual operation, and improves processing efficiency.

[0031] During disassembly and installation, the top plate 2 is embedded into the receiving groove 4, the positioning pin 51 is inserted into the positioning hole 41, and the slide rod 52 is pressed down by gravity or the return spring 53. Through the squeezing action of the ball bearing 54 and the extrusion port, the ball bearing 54 is locked into the fixed slide groove to complete the fixation. During disassembly, the upper lifting ring 55 drives the slide rod 52 to rise, the ball bearing 54 is disengaged from the fixed slide groove, and the positioning pin 51 can be pulled out to separate the top plate 2. With the positioning component 5, the top plate 2 can be quickly disassembled and replaced during disassembly and maintenance, and tool-free quick disassembly and assembly of the top plate 2 can be achieved, which is convenient for equipment maintenance and cleaning.
