Description

Technical Field

[0001] The utility model relates to the technical field of garden tools, in particular to a tree root tooth convenient for assembly. Background Technique

[0002] Trees are the general term for woody plants, which have woody trunks and branches and can survive for many years. Special-purpose forests refer to the cultivation of specific types of trees to meet people's special needs. These trees are usually characterized by rapid growth, strong environmental adaptability, high-quality wood, high economic value, etc. The planting of special-purpose forests can provide various resources such as wood, fiber, medicinal materials, and fruits, and at the same time, it also has social and ecological benefits such as soil and water conservation and environmental improvement. After the trees are cut down, the tree trunks are easy to process, and the branches are easy to handle, but the tree roots are difficult to deal with. Therefore, a tree digger is often used to dig out the tree roots and then crush them for subsequent utilization.

[0003] Some existing tree diggers replace the bucket of the excavator with a tree root tooth shaped like a fork. The tree root tooth is inserted into the soil by the hydraulic power of the excavator and then the tree root is pulled out. However, when replacing and installing the tree root tooth, the operator often needs to spend a long time aligning the installation hole at the end of the stick with the installation hole at the top of the tree root tooth and then fixing it with screws. Since the working environment is mostly harsh and the fixing screws are usually large and require a large torque to tighten, most of them are manually installed by hand, resulting in a time-consuming and laborious process.

[0004] In view of this, this application is specifically proposed. Content of the Utility Model

The length direction of the installation part is consistent with the length direction of the tree root tooth body. Transverse storage channels one are provided in the middle of both ends of one side wall of the installation part along the length direction. A storage groove is arranged inside one of the installation parts. Two vertical fixing mechanisms are arranged in the storage groove along the length direction of the installation part.

Limiting plates three are fixedly connected to the outer arc walls of the five rotating shafts. One end of the limiting plate three far away from the center of the circle formed by the five rotating shafts is rotatably connected to a fixing rod. One ends of the five fixing rods far away from the limiting plate three are all rotatably connected to the same rotating ring. One end of the fixing rod far away from the limiting plate three is rotatably connected to one side wall of the rotating ring. A worm gear is fixedly connected to the side wall of the rotating ring far away from the fixing rod. The bottoms of the two worm gears are both meshed with the same worm.

[0008] Furthermore, on the side wall of the installation part on the other side away from the fixing mechanism, two limiting plates one are symmetrically arranged on both sides. The limiting plate one is in a U shape and the open end faces the center of the side wall of the installation part close to the limiting plate one. The limiting plate one is located on the side where the two storage channels one are away from each other, and the limiting plate one is fixedly connected to the side of the opening of the storage channel one.

[0009] Furthermore, the same fixing pin one is pin-connected in the storage channels one on the two installation parts. A limiting block is fixedly connected to the side wall of the fixing pin one close to the limiting plate one. A convex block is fixedly connected to one side of the outer arc wall of the limiting block, and the convex block is adapted to the limiting plate one.

[0010] Furthermore, a fixing pin two is fixedly connected to the side wall of the fixing pin one close to the fixing mechanism. Five grooves one are arranged on the outer arc wall of the fixing pin two in an annular array distribution, and the grooves one are adapted to the end of the limiting plate three away from the rotating shaft and the fixing rod.

[0011] Furthermore, when the convex block on the outer arc wall of the limiting block is embedded in the limiting plate one, the fixing pin two is located in the storage channel two inside the installation part, and the five grooves one correspond to the five limiting plates three one by one.

[0012] Furthermore, two limiting plates two are fixedly connected to both ends of the side wall of the two installation parts close to each other. The limiting plate two is located at the outer bottom end of the opening of the storage channel one. The cross-section of the limiting plate two is a fan-shaped ring, and the arc of the cross-section of the limiting plate two is parallel to the arc of the cross-section of the storage channel one.

Through the fixing component, controlling the rotation of the worm can quickly fix the fixing pin, and the grooves arranged on the outer arc wall of the fixing pin two are adapted to the limiting plates in the fixing component.

The second limiting plate can facilitate the operator to align the pin hole at the end of the bucket rod with the pin hole at the top of the root tooth during installation, further saving installation time.

In the middle of both ends of one side wall of the mounting parts 11 along the length direction, there are horizontally penetrating storage channels one. Inside one of the mounting parts 11, there is a storage groove. Along the length direction of the mounting parts 11 in the storage groove, there are two vertical fixing mechanisms 40. The fixing mechanism 40 includes five rotating shafts 44 fixedly connected to one side wall of the storage groove and distributed in an annular array. On the outer arc walls of the five rotating shafts 44, there are fixedly connected limit plates three 43. One end of the limit plate three 43 far from the center of the circle formed by the five rotating shafts 44 is rotatably connected to a fixing rod 42.

On the side wall of the rotating ring 41 far from the fixing rod 42, there is fixedly connected a worm gear 31. The bottoms of the two worm gears 31 are both meshed with the same worm 30.

[0032] It should be noted that the outer arc wall of one end of the worm 30 located outside the mounting part 11 is a regular polygon structure. One of the methods such as using a wrench, power tool, welding handle, etc. can be used to rotate the worm 30. One end of the rotating shaft 44 close to the limit plate three 43 is fixedly connected with a fixing piece. On the side wall of the rotating shaft 44 close to the limit plate three 43, there is detachably connected a fixing piece with the same structure, that is, the limit plate three 43 is located between the two fixing pieces, and the fixing piece prevents the limit plate three 43 from running off;

[0033] The limit plate three 43 is L-shaped. One end of the limit plate three 43 is rotatably connected to the rotating shaft 44. The middle part of the limit plate three 43 is rotatably connected to the fixing rod 42. The other end of the limit plate three 43 is arranged towards the center of the storage channel two.

[0034] Refer to Figures 1-6 As shown, for the tree root tooth convenient for assembly, one end of the worm 30 is rotatably connected to the inner side wall of the storage groove. The other end of the worm 30 penetrates the side wall of the mounting part 11. In the center of one side wall of the worm gear 31, there is a horizontally penetrating storage channel two. The storage channel one and the storage channel two are coaxially arranged and have equal cross-sectional radii.
