Description

Technical Field

[0001] The utility model relates to the technical field of clamping saws, and particularly relates to a clamping saw capable of 360-degree rotation. Background Art

[0002] A log grapple is generally evolved from a hydraulic excavator. The biggest difference between a log grapple and an ordinary excavator lies in the different front working devices, that is, different working purposes: the boom and arm of an ordinary excavator are generally shorter, and the front end is a bucket, whose main function is to carry out excavation and loading operations; the boom and arm of a log grapple are commonly called "material-grabbing arms", which are generally longer and have a different shape and structure from those of an ordinary excavator. The front end is a log grapple, and its main function is to carry out the loading, unloading and handling operations of wood, lumber, reeds, straw and various strip-shaped materials.

[0003] The log grapple can only fix the wood, but in forestry operations, the wood also needs to be cut for subsequent use. However, it needs to be transported to a cutting machine for cutting, which not only increases the work burden but also results in low work efficiency. Summary of the Utility Model

[0024] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0025] Please refer to Figures 1-5 , a 360-degree rotatable clamping saw, including a mounting frame 1, a rotator 11 fixedly connected to the mounting frame 1, the rotator 11 being fixedly connected to a support frame 12, and a clamping assembly 2 connected to the support frame 12; further including a cutting assembly 3 provided on one side of the support frame 12, the cutting assembly 3 being capable of moving in a direction closer to or farther from the support frame 12.

[0026] The mounting frame 1 is respectively rotatably connected to the robotic arm and the hydraulic arm of the excavator, so that the mounting frame 1 can rotate relative to the excavator; the rotator 11 is an electric rotator 11, so that the support frame 12 can rotate 360 degrees relative to the mounting frame 1 to facilitate clamping of wood at different inclinations.

[0027] By providing the clamping assembly 2, the mounting frame 1 is fixed to the excavator body, rotated by the rotator 11 to adjust the position of the clamping assembly 2, then the cut wood is fixed by the clamping assembly 2, and then the position of the cutting assembly 3 is adjusted to cut the wood. The present utility model can complete the fixation and cutting of wood, and can also adjust the cutting position, avoiding the problem of repeatedly moving the clamping assembly 2 to adjust the cutting position.

[0028] Further, the clamping assembly 2 includes a left clamping jaw 21 and a right clamping jaw 22 which are respectively rotatably connected to the support frame 12. The left clamping jaw 21 and the right clamping jaw 22 are arranged oppositely and are both connected to the power assembly.

[0029] Further, a slot 23 capable of accommodating the right clamping jaw 22 is provided on the left clamping jaw 21. When the left clamping jaw 21 and the right clamping jaw 22 approach each other, the right clamping jaw 22 can extend into the left clamping jaw 21, so as to facilitate storage and reduce the floor space.

[0030] Further, the power assembly includes a first motor 24 fixedly connected to the support frame 12. A left rotating rod 25 is fixedly connected to the output end of the first motor 24. A driving gear 27 is fixedly connected to the left rotating rod 25. The driving gear 27 is meshed and connected with a driven gear 28. The driven gear 28 is fixedly connected to a right rotating rod 26. Both the left rotating rod 25 and the right rotating rod 26 are rotatably connected within the support frame 12. The left rotating rod 25 is fixedly connected to the left clamping jaw 21, and the right rotating rod 26 is fixedly connected to the right clamping jaw 22.

[0031] The first motor 24 drives the left rotating rod 25 to rotate. The rotation of the left rotating rod 25 drives the right rotating rod 26 to rotate through the driving gear 27 and the driven gear 28. The left rotating rod 25 and the right rotating rod 26 respectively drive the left clamping jaw 21 and the right clamping jaw 22 to rotate, so as to fix or loosen the wood.

[0032] Further, the cutting assembly 3 includes two first hydraulic cylinders 31 fixedly arranged on the support frame 12. The output ends of the two first hydraulic cylinders 31 are both fixedly connected to a cutting frame 32. A second motor 33 is installed in the cutting frame 32. The output end of the second motor 33 is fixedly connected to the sprocket of a chain saw 34, and the sprocket is connected to a rotating assembly.

[0033] By changing the relative position of the chain saw 34 and the mounting frame 1 through the first hydraulic cylinder 31, the wood at different positions can be cut.

[0034] Further, the rotating assembly includes a second hydraulic cylinder 35 fixedly installed on the cutting frame 32. A driving rod 36 is fixedly connected to the end of the second hydraulic cylinder 35. A sliding rod 37 is fixedly connected to the chain saw 34. The sliding rod 37 is respectively slidably connected to a first sliding groove 38 on the driving rod 36 and a second sliding groove 39 on the cutting frame 32. To improve the stability of the sliding process of the sliding rod 37, the other end of the sliding rod 37 can also be slidably connected to the cutting frame 32, and this setting can also assist in supporting the chain saw 34.

[0035] The second hydraulic cylinder 35 drives the driving rod 36 to move. The movement of the driving rod 36 drives the sliding rod 37 to move along the second sliding groove 39, so that the chain saw 34 makes a rotating motion, that is, the chain saw 34 extends from the cutting frame 32 to cut the wood and resets after cutting.

[0036] Working principle: Fix the mounting bracket 1 on the main body of the excavator, rotate it through the rotator 11 to adjust the position of the clamping assembly 2, then fix the cut wood through the clamping assembly 2, and then adjust the position of the cutting assembly 3 to cut the wood. The utility model can complete the fixation and cutting of wood, and can also adjust the cutting position, avoiding the problem of repeatedly moving the clamping assembly 2 to adjust the cutting position.

[0037] Only some exemplary embodiments of the present utility model have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
