[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a large timber processing handling device, including a base frame 1, a side frame 21 fixedly connected to the top of the base frame 1, a first universal wheel 22 installed at the bottom of the base frame 1, an extension rod 23 slidably connected to the base frame 1, a second universal wheel 24 installed at the bottom of the extension rod 23, a drive assembly installed on the base frame 1, an adjustment assembly installed on the side frame 21, and a fastening assembly installed between the side frame 21 and the adjustment assembly. The drive assembly drives the extension rod 23 to slide on the base frame 1. The first universal wheel 22 and the second universal wheel 24 have a self-locking function, which positions the device. Timber is placed on the base frame 1 by a crane, and initially passes through the side frame 21. The base frame 1 is positioned for this purpose. A baffle is installed on the extension rod 23 to initially position the bottom layer of wood. The extension rod 23 can be slid by the drive component to expand the load-bearing range of the extension rod 23 and the base frame 1 as needed. After the wood is stacked, the position of the fastening component is adjusted by the adjustment component. Then, the connecting rod 55 is taken out and locked into the corresponding first card plate 57 or second card plate 58. The wood is then tied tightly by the fastening component. The positioning of the fastening component makes the wood stably positioned on the base frame 1 and the side frame 21. The base frame 1 has a hollow groove at the corresponding position of the first threaded rod 35. If wood chips enter the groove of the base frame 1, they can be discharged through the hollow groove.

[0024] Please see Figure 1 - Figure 3 A further solution based on this embodiment is as follows: the base frame 1 has a matching groove at the corresponding position of the extension rod 23, and the extension rod 23 slides inside the matching groove. The groove limits the sliding of the extension rod 23, so that the extension rod 23 slides smoothly in a straight line, and avoids the extension rod 23 from tilting due to pressure.

[0025] Please see Figure 2 A further solution based on this embodiment is as follows: the drive assembly includes a first motor 31 fixedly connected to the base frame 1, a rotating shaft 32 fixedly connected to the output end of the first motor 31, a sprocket 33 fixedly connected to the rotating shaft 32, a chain 34 meshing with the sprocket 33, and a first threaded rod 35 fixedly connected to the rotating shaft 32. The rotating shaft 32 is rotatably connected to the base frame 1. The position of the extension rod 23 is adjusted by the first threaded rod 35, and the extension rod 23 is driven by the threaded pair of the first threaded rod 35, which can form a self-locking mechanism, thereby automatically positioning the position of the extension rod 23 and preventing the extension rod 23 from sliding on its own.

[0026] Please see Figure 2 A further solution based on this embodiment is as follows: There are two rotating shafts 32, and the two rotating shafts 32 are symmetrically arranged on the base frame 1. Each of the two rotating shafts 32 is provided with a sprocket 33, and a chain 34 is engaged with the two sprockets 33. The chain 34 provides stable transmission, thereby ensuring that the two first threaded rods 35 rotate synchronously, thereby driving the two extension rods 23 to slide synchronously.

[0027] Please see Figure 3 , Figure 5 A further solution based on this embodiment is as follows: the adjustment component includes a second motor 41 fixedly connected to the side frame 21, a second threaded rod 42 fixedly connected to the output end of the second motor 41, and a sliding frame 43 threadedly connected to the second threaded rod 42. The sliding frame 43 slides on the side frame 21 and can appropriately adjust the position of the fastening component, so that the fastening component can more fully wrap the wood and avoid leaving gaps that would cause the wood to be unstable.

[0028] Please see Figure 1 , Figure 3 - Figure 4A further solution based on this embodiment is as follows: The fastening assembly includes a take-up seat 51 fixedly connected to the sliding frame 43, a self-locking motor 52 fixedly connected to the take-up seat 51, a take-up roller 53 fixedly connected to the output end of the self-locking motor 52, a rope 54 fixedly connected to the take-up roller 53, a connecting rod 55 fixedly connected to the end of the rope 54 away from the take-up roller 53, a placement block 56 fixedly connected to the side frame 21, a first clamping plate 57 fixedly connected to the base frame 1, and a second clamping plate 58 fixedly connected to the extension rod 23. The rope 54 is wrapped around the surface of the wood, and the self-locking motor 52 tightens the rope 54 to position the wood. The self-locking motor 52 has a self-locking function, which means that after the power is cut off or the power supply is stopped, the motor can maintain the position of the output shaft by its own structure or external device to prevent external force from causing rotation, thereby automatically positioning after the rope 54 is wound up.

[0029] Please see Figure 3 - Figure 5 A further solution based on this embodiment is as follows: the side frame 21 has a through groove at the corresponding position of the sliding frame 43, and the sliding frame 43 slides inside the through groove. The rope 54 passes through the through groove and the sliding frame 43 is laterally positioned through the through groove, so that the sliding frame 43 can only slide up and down. This prevents the sliding frame 43 from leaving the through groove while ensuring that the sliding frame 43 slides smoothly.

[0030] Please see Figure 1 - Figure 2 A further solution based on this embodiment is as follows: the placement block 56, the first card plate 57 and the second card plate 58 are respectively provided with card slots that are adapted to the connecting rod 55, and the connecting rod 55 is engaged in the card slot. The position of the connecting rod 55 is positioned by the card slot, so that the connecting rod 55 will not fall off when the rope 54 is tightened.

[0031] Working principle: The first motor 31 drives the rotating shaft 32, which in turn drives the first threaded rod 35 to rotate. Simultaneously, the rotating shaft 32 drives the sprocket 33, which in turn drives another sprocket 33 via a chain 34. This causes the two rotating shafts 32 and the first threaded rod 35 to rotate synchronously. The first threaded rod 35 drives the extension rod 23 to slide, expanding it to the required size. The timber is then placed on the extension rod 23 and the base frame 1. A baffle is installed on the extension rod 23 to initially position the timber at its lowest point, in conjunction with the side frame 21. The second motor 41 then drives... The second threaded rod 42 is rotated, which drives the sliding frame 43, which in turn drives the take-up seat 51. The take-up seat 51 is adjusted to a position slightly lower than the top of the wood. Then, the worker takes the connecting rod 55 and wraps the rope 54 around the wood. The connecting rod 55 is then placed inside the first clamping plate 57 or the second clamping plate 58. The self-locking motor 52 is then started, which drives the take-up roller 53 to rotate. The take-up roller 53 rotates to wind up the rope 54, tightening the rope 54, thereby positioning the wood through the rope 54.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
