Description

Technical Field

[0001] This utility model relates to a log gripper for excavators that can straighten timber, belonging to the field of log gripper technology. Background Technology

[0002] Log grapples are a common attachment on excavators. They are mainly used for loading, unloading and transporting timber. Timber piles are generally unloaded and then stacked into dense stacks without partitions for storage and transportation. Unloading can be done manually or by mechanization or semi-mechanization. Manual unloading is dangerous and cumbersome, so machinery should be used as much as possible. Log grapples are based on wheeled or tracked tractors, with a log grapple mounted on the front end of their boom.

[0003] For example, the wood gripper disclosed in patent publication number CN219508680U can straighten wood. When the drive motor is started, the wood gripper moves the clamping plates on both sides toward the center through the cooperation of the set moving groove, the bidirectional lead screw and the moving block to clamp and fix the wood. When the clamping plates on both sides are in contact with the wood at the same time, they will squeeze the pressing block, so that the buttons on both sides are pressed at the same time, stopping the drive motor and avoiding damage to the wood or the device due to over-clamping.

[0004] The above-mentioned patented equipment can prevent damage to wood or devices caused by excessive clamping; however, such equipment has the following drawbacks when in use:

[0005] 1. This type of equipment has two clamping plates that can be brought close together, and their length is not easily adjustable. When transporting large quantities of timber, the transportation efficiency is slow because the length is inconvenient to adjust.

[0006] 2. Since the surface of wood is not entirely smooth due to artificial treatment, there may be branches or forks on the surface. These branches may affect the efficiency of clamping the wood, and existing equipment is not convenient for cutting the branches.

[0007] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-5As shown, an excavator-mounted log grappling device for straightening timber includes a quick-change connector 1 and a clamping frame 2. A hub motor 3 is fixedly installed at the bottom of the quick-change connector 1. The clamping frame 2 is located below the hub motor 3. A drive plate 4 is symmetrically slidably installed inside the clamping frame 2. A drive assembly 5 for the opposing movement of the drive plate 4 is provided inside the clamping frame 2. A docking clamping plate 6 is provided below the drive plate 4. A height adjustment assembly 7 for adjusting the lifting and lowering of the docking clamping plate 6 is provided on one side of the drive plate 4. A cutting blade 9 is fixedly installed on one side of the docking clamping plate 6 via a support rod 8. This device controls the hub motor 3, drive motor 501, and adjustment motor through a controller on the excavator. Since the controller is a common existing device on the market, its structure is not described in this device. The height adjustment assembly 7 enables the lifting and lowering of the docking clamping plate 6, thereby allowing the device to fork more timber. The cutting blade 9 facilitates the removal of branches from the timber.

[0026] like Figure 2 As shown, a rotating cylinder 10 is fixedly installed above the clamping frame 2. The output end of the hub motor 3 is fixedly connected to the rotating cylinder 10. The hub motor 3 is controlled by the controller to turn on, so that the rotating cylinder 10 and the support frame can be driven to rotate by the hub motor 3, thereby enabling the excavator operator to flexibly operate the device.

[0027] like Figure 2 As shown, the drive assembly 5 includes a drive motor 501 and a bidirectional lead screw 502. The drive motor 501 is fixedly mounted on one end of the clamping frame 2 through a motor housing. A limit groove is opened inside the clamping frame 2. The bidirectional lead screw 502 is rotatably mounted inside the limit groove. One end of the bidirectional lead screw 502 is fixedly connected to the output end of the drive motor 501. A lead screw hole is opened on the drive plate 4. The drive plate 4 is symmetrically meshed on the bidirectional lead screw 502 so that by turning on the drive motor 501, the drive motor 501 drives the bidirectional lead screw 502 to rotate, thereby enabling the drive plate 4 to drive the docking clamping plate 6 to move in opposite directions, thereby realizing the clamping of the wood.

[0028] like Figure 2As shown, the height adjustment assembly 7 includes a fixed platform 701, which is symmetrically fixedly installed on one side of the drive plate 4. A roller 702 is rotatably installed between the fixed platforms 701. A take-up belt 703 is symmetrically wound on the roller 702. One end of the take-up belt 703 passes through the interior of the drive plate 4 and extends downward to be fixedly connected to the docking clamping plate 6. A take-up motor 704 is fixedly installed on one end of the roller 702. The take-up motor 704 is fixedly installed on the fixed platform 701. A stabilizing rod 705 is symmetrically provided at the lower end of the drive plate 4. The lower end of the stabilizing rod 705 is inserted into the interior of the docking clamping plate 6 so that when the take-up motor 704 is turned on, it can drive the roller 702 to rotate. At this time, the lower end of the take-up belt 703 begins to move with the downward movement of the docking clamping plate 6. The take-up belt 703 is made of high-strength steel material, which can ensure the strength of the take-up belt 703.

[0029] like Figure 2 As shown, curved blades 11 are symmetrically fixed to the end of the clamping plate 6 below one end of the clamping frame 2. This allows the cutting blades 9 and curved blades 11 to cut the branches on the wood when the worker clamps the wood with this device. Both the cutting blades 9 and curved blades 11 are curved, which can adapt to the shape of round wood, thereby improving the practicality of this device.
