[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figures 1 to 3As shown, the utility model provides an embodiment: a forest tree felling auxiliary device, including a support strip 1, the bottom of the support strip 1 is fixedly connected to a mounting block 2, and the mounting block 2 serves to connect the support strip 1 and the holding assembly. The internal rotation of the mounting block 2 is connected to a holding assembly for shaking, and the holding assembly includes a limit shaft 3. The limit shaft 3 serves as a core component of rotation, and its surface is smooth and can rotate flexibly in the mounting block 2. The external rotation of the limit shaft 3 is connected to the inside of the mounting block 2 to ensure smooth rotation of the limit shaft 3. The front and rear sides of the limit shaft 3 are fixedly connected with a rotating handle 4, which serves as an operating part to facilitate the operator to hold and rotate. The outside of the holding assembly is fixedly connected to a roller 5;

[0031] Driven by the limiting shaft 3, the roller 5 rotates, retracting and extending the connecting belt 6. The outer portion of the roller 5 is rotatably connected to the interior of the mounting block 2, ensuring stable rotation. The connecting belt 6 is sheathed around the outer portion of the roller 5. As the power transmission component, the connecting belt 6 has moderate strength and toughness, capable of withstanding a certain amount of tension. A collar 7 is fixedly attached to one side of the connecting belt 6, connecting it to the limiting block 15.

[0032] Reference Figures 1 to 2 As shown, a chute 8 is provided inside the support slat 1, and the chute 8 provides a track for the sliding of the support block 9. The support block 9 is slidably connected inside the chute 8. As a component for supporting and pushing the tree, the support block 9 has a reasonable shape and size, which can contact the tree and generate sufficient thrust. A limit assembly is provided on the top of the support slat 1 for engagement. The limit assembly includes a placement groove 10 and a limit rod 11. The placement groove 10 is used to place the limit rod 11 for easy operation. The outside of the limit rod 11 engages with the inside of the limit block 15 to ensure that the limit rod 11 can limit the limit block 15. The outside of the limit rod 11 is slidably connected to the inside of the support block 9 to ensure smooth movement of the limit rod 11.

[0033] Reference Figures 1 to 3 As shown, the outside of the placement slot 10 is opened at the top of the support strip 1 for easy operation. The outside of the limit rod 11 is slidably connected to the inside of the support block 9 to ensure that the limit rod 11 can limit the support block 9. The inside of the support block 9 is rotatably connected to a rotating plate 12, which can rotate within the support block 9 to adjust the angle for better contact with the tree. The bottom of the rotating plate 12 is fixedly connected with a plurality of protruding nails 13, which can be inserted into the ground to increase the friction between the rotating plate 12 and the ground to prevent sliding. A limiting groove 14 is opened inside the support strip 1, and the limiting groove 14 provides a track for the sliding of the limiting block 15;

[0034] The internal sliding connection of the limiting groove 14 is connected to a limiting block 15. As a connecting component, the limiting block 15 can slide within the limiting groove 14 to transmit power. The bottom of the limiting block 15 is fixedly connected to a connecting block 16, which is used to connect the limiting block 15 and the lifting assembly. The bottom of the limiting block 15 is fixedly connected to a lifting assembly for connection. The lifting assembly includes multiple cone spikes 17 and a grooved block 18. The cone spikes 17 can be inserted into the tree to increase friction with the tree and facilitate lifting. The top of the cone spike 17 is fixedly connected to the bottom of the connecting block 16 to ensure that the cone spike 17 is firmly connected.

[0035] Reference Figure 4 As shown, the rear side of the slotted block 18 is fixedly connected to the front side of the mounting block 2, ensuring that the slotted block 18 is securely installed. A telescopic rod 19 is fixedly connected to the interior of the slotted block 18. The telescopic rod 19 can be extended and retracted within the slotted block 18, providing support for the spring 20. A spring 20 is sleeved on the exterior of the telescopic rod 19. The spring 20 can be extended and retracted under the action of the telescopic rod 19, providing elastic force for the slider 21. One side of the spring 20 is fixedly connected to the interior of the slotted block 18, ensuring that the spring 20 is securely connected. The other side of the spring 20 is fixedly connected to the rear side of the slider 21, ensuring that the spring 20 can generate elastic force on the slider 21.

[0036] The front of the telescopic rod 19 is fixedly connected to the rear of the slider 21, ensuring that the telescopic rod 19 can provide support for the slider 21. The slider 21 has a triangular shape, which better cooperates with the rotating handle 4 to achieve both blocking and labor-saving functions. The slider 21 is slidably connected to the interior of the grooved block 18, ensuring that the slider 21 can slide within the grooved block 18.

[0037] Working principle: When felling trees in the forest, the felled trees need to be tilted in a specific direction. At this time, they only need to insert the right side of the supporting strip 1 into the ground behind the tree to be felled, and then rotate the rotating handle 4 so that the rotating handle 4 cooperates with the limiting shaft 3 to drive the roller 5 to rotate, so that the roller 5 retracts the connecting belt 6. Then, when the connecting belt 6 retracts, it drives the limiting block 15 to slide inside the limiting groove 14 through the collar 7. Then, the limiting block 15 cooperates with the limiting rod 11 to drive the supporting block 9 to slide inside the supporting strip 1. Then, the supporting block 9 is extended and retracted to the appropriate position, so that the supporting block 9 cooperates with the rotating plate 12 to push the back side of the tree to be felled, and at the same time, the convex nail 13 is inserted into the ground to prevent it from falling off, so that the rotating plate 12 generates a pushing force on the back side of the tree to be felled, so as to prevent it from hitting surrounding buildings, power lines, personnel or other important facilities after being felled.

[0038] Then, after the tree is cut down, it is difficult to lift it for binding or subsequent operations. At this time, you only need to pick up the supporting strip 1 and insert the cone nail 17 into the end of the cut tree, and then pull out the limit rod 11 from the inside of the support block 9. Then, by turning the handle 4 and the limit shaft 3, the roller 5 is driven to rotate, so that the roller 5 drives the connecting belt 6 and the ring 7 to retract the limit block 15, and then the limit block 15 cooperates with the cone nail 17 to slowly lift the inside of the supporting strip 1 while driving one end of the cut tree to lift. At the same time, the rotating handle 4 squeezes the slider 21 while rotating, so that the slider 21 slides inside the grooved block 18. After the rotating handle 4 rotates past the slider 21, the slider 21 is pushed back by the spring 20, and then the slider 21 blocks the rotating handle 4, making it more labor-saving to lift the tree.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
