PREFERRED EMBODIMENT

[0018] 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.

[0019] This utility model provides, for example Figures 1-4 The clamping logging machine shown includes two side plates 1, which are rotatably connected to each other by a connecting rod. The connecting rod includes several adjacent rotating rods 2. The rod wall of the rotating rod 2 is fixedly connected to a clamping arm 3. The clamping arm 3 is curved and has a through hole 31 along its inner wall. Both side walls of the through hole 31 have multiple equally spaced sliding grooves 33 along their inner walls. The inner walls of both sliding grooves 33 are fixedly connected to springs 34. The same end of the two springs 34 is fixedly connected to a sliding plate 35. The side of the sliding plate 35 facing the center of the clamping arm 3 is fixedly connected to a trapezoidal cone head 32. The base of the trapezoidal cone head 32 is trapezoidal and the top is conical. The top surfaces of the two side plates 1 are fixedly connected to a detachable connecting plate 5. The top surface of the connecting plate 5 is provided with a rotatable mounting seat 6. One side of one of the side plates 1 is provided with a driving device for driving the clamping arm 3 to rotate.

[0020] First, the mounting base 6 is installed on the robotic arm of the logging machine. Then, the robotic arm moves the mounting base 6 so that the bottom surface of the side plate 1 fits into the bark. After fitting, the drive motor 4 is started. The output end of the drive motor 4 drives the output gear 41 to rotate. The output gear 41 drives the transmission gear 23 meshing with the output gear 41 to rotate. The two transmission gears 23 rotate in opposite directions, which causes the clamping arms 3 on the two connecting rods to perform a clamping action. During clamping, the trapezoidal cone 32 squeezes the bark. The squeezing of the bark by the trapezoidal cone 32 causes the slide plate 35 to move backward, which in turn squeezes the spring 34, thus fixing the tree trunk. Since the top surface of the trapezoidal cone 32 is trapezoidal, the top of the trapezoidal cone 32 will penetrate into the bark, preventing the sawn tree from slipping with the clamping arm 3 during clamping and avoiding injury to nearby workers.

[0021] like Figure 3 As shown, the clamping arm 3 is located at the center of the rotating rod 2. One end of the rotating rod 2 is fixedly connected to a U-shaped insert plate 21, and the other end of the rotating rod 2 is provided with an insertion hole 22. A pin is inserted into the U-shaped insert plate 21 through the insertion hole 22.

[0022] By fixing the pin through the insertion hole 22 to the U-shaped insertion plate 21, it is possible to fix two adjacent rotating rods 2, which facilitates the replacement of the clamping arm 3.

[0023] As shown in Figure 2 The same end of the two connecting rods is fixedly connected with a transmission gear one 23, the two transmission gears one 23 are meshingly connected, and the driving device is close to the side plate 1 on one side of the transmission gear one 23.

[0024] As shown in Figure 1 And Figure 2 The driving device comprises a driving motor 4 fixed on one side of the side plate 1, the output end of the driving motor 4 penetrates the side plate 1, and the output end of the driving motor 4 is fixedly connected with an output gear one 41, which is meshingly connected with the transmission gear one 23;

[0025] The driving motor 4 drives the output gear one 41 to rotate, the output gear one 41 drives the transmission gear one 23 to rotate, so that the two meshing transmission gears one 23 are reversed, and the clamping and opening of the two clamping arms 3 are realized.

[0026] As shown in Figure 2 And Figure 4 The L-shaped plate on the bottom surface of the connecting plate 5 is fixedly connected with an adjusting motor 7, the output end of the adjusting motor 7 is fixedly connected with an output gear two 71 penetrating the through slot on the top surface of the connecting plate 5, the bottom surface of the mounting seat 6 is fixedly connected with a connecting shaft 61, the bottom end of the connecting shaft 61 is rotatably connected with the connecting plate 5, and the outer wall of the connecting shaft 61 is fixedly connected with a transmission gear two 62 meshingly connected with the output gear two 71;

[0027] The adjusting motor 7 drives the output gear two 71 to rotate, the output gear two 71 rotates along the outer wall of the transmission gear two 62, and since the bottom of the adjusting motor 7 is fixed with the L-shaped fixed plate on the bottom surface of the connecting plate 5, the connecting plate 5 can rotate, so that the tree trunk after clamping is turned over, facilitating the moving and stacking of the tree trunk.

[0028] As shown in Figure 1 The top surface of the connecting plate 5 is fixedly connected with the side plate 1 through bolts, so that the side plate 1 and the connecting plate 5 can be separated, and the connecting rod 2 between the two side plates 1 can be spliced.

[0029] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
