Description

Technical Field

[0001] The utility model relates to the technical field of pruning equipment, in particular to a pruning machine which is easy to adjust. Background Art

[0002] The tea tree is an evergreen shrub of the genus Camellia in the Theaceae family, often in the form of a clumping shrub; the leaves are thin and leathery, elliptic-lanceolate or oblong, with short petioles and blunt tips; the flowers are in cymes, white, with recurved pedicels; the capsules are spherical; the seeds are brown-brown. During the tea tree planting process, the branches of the tea tree need to be pruned regularly to ensure that it grows a good-looking appearance and to prevent too many branches from affecting its growth. A pruning machine is needed for pruning it, and ordinary pruning machines are extremely inconvenient to operate when pruning some taller tea trees.

[0003] When a pruning machine is used to prune taller tea tree branches, the pruning device needs to be extended into the tea tree. The existing pruning machine cannot adjust the size of the pruning tool according to the actual environment inside the tea tree, which easily leads to low efficiency or inconvenient operation. For this reason, we propose a pruning machine that is easy to adjust. Utility Model Content

[0004] In view of the above problems, the utility model provides a pruning blade of suitable size which can be selected according to the specific conditions inside the tea trees on site during use. The larger pruning blade can be used to conveniently prune thicker branches, which helps to improve pruning efficiency. In the densely packed tea tree branches below, a small pruning blade is used to facilitate pruning operations.

[0024] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0025] Example:

[0026] like Figure 1-Figure 4 As shown, a trimmer that is easy to adjust includes:

[0027] A U-shaped housing 1, a handle 2 is fixedly connected to the left side of the U-shaped housing 1, an anti-slip sleeve 3 is fixedly connected to the left end of the handle 2, and a pull ring 4 is fixedly connected to the outer side of the handle 2;

[0028] An adjustment mechanism 6, which is arranged inside the U-shaped housing 1 and is used to select a pruning tool of a suitable size according to an actual pruning environment;

[0029] The power assembly 5 is arranged on the top of the U-shaped housing 1 and is used to provide stable power for the use of the shearing tool.

[0030] The working principle of the above technical solution is as follows:

[0031] The pruning operation is facilitated by the action of the handle 2, the pull ring 4 and the anti-slip cover 3. A pruning blade 605 of suitable size is selected according to the actual use environment on site. The limit of the block 609 is cancelled during adjustment. The rotating bar 604 is rotated by the rotating block 603. After adjusting to an appropriate position, the block 609 enters the slot 608 again. At this time, the position of the pruning blade 605 is limited by the action of the block 609 and the slot 608. Under the action of the pruning blade 605, the pruning blade 605 can be inserted into the tea tree to prune branches.

[0032] When adjusting the pruning blade 605, the position of the driving gear 505 can be adjusted through the electric telescopic rod 504 so that it will not affect the adjustment of the pruning blade 605. After the adjustment, the driving gear 505 is reset, and the pruning blade 605 can be driven to rotate under the action of the driving gear 505 to prune the tea tree.

[0033] In another embodiment, if Figure 3 As shown, the adjustment mechanism 6 includes a rotating shaft 607, which is movably connected to the inner side of the U-shaped shell 1 through a bearing, and a rotating bar 604 is fixedly connected to the outer side of the rotating shaft 607. The rotating bar 604 is provided with mounting grooves 601 on both sides, and a transmission rod 606 is movably connected to the inner side of the mounting groove 601 through a bearing, and two trimming blades 605 of different sizes are fixedly connected to the outer sides of the two transmission rods 606.

[0034] The rotating bar 604 can be rotated under the action of the rotating shaft 607 to adjust the size of the trimming blade 605 , and the two trimming blades 605 of different sizes can be driven to rotate under the action of the transmission rod 606 .

[0035] In another embodiment, if Figure 3 As shown, the bottom end of the rotating shaft 607 passes through the bottom of the U-shaped housing 1 , and the bottom end of the rotating shaft 607 is fixedly connected to a rotating block 603 , and a slot 608 is provided on the outer side of the rotating block 603 .

[0036] The rotating shaft 607 can be easily rotated under the action of the rotating block 603 , and the rotating block 603 can be limited under the action of the clamping slot 608 and the clamping block 609 .

[0037] In another embodiment, if Figure 3 As shown, a rectangular shell 602 is fixedly connected to the bottom of the U-shaped shell 1 , a movable block 612 is slidably connected to the inner side of the rectangular shell 602 , and a clamping block 609 is fixedly connected to the right side of the movable block 612 .

[0038] The movable block 612 can drive the clamping block 609 to move, and the clamping block 609 and the clamping slot 608 can limit the rotation block 603 to prevent it from rotating by itself, thereby ensuring the stability of the trimming blade 605 when in use.

[0039] In another embodiment, if Figure 3 As shown, a spring 610 is fixedly connected to the left side of the movable block 612, and the spring 610 is fixedly connected to the inner side of the rectangular shell 602. A pull block 611 is fixedly connected to the bottom of the movable block 612. A long groove is opened at the bottom of the rectangular shell 602, and the bottom end of the pull block 611 passes through the long groove.

[0040] The spring 610 facilitates the block 609 to enter the slot 608 , and the pull block 611 can pull the movable block 612 to move, so that the block 609 leaves the slot 608 and the limit on the rotating block 603 is cancelled.

[0041] In another embodiment, if Figure 4 As shown, the power assembly 5 includes a U-shaped block 503, which is arranged above the U-shaped shell 1. The top of the U-shaped block 503 is fixedly connected to the motor 502. The motor 502 is fixedly connected to a rotating rod 506 through an output shaft. The outer side of the rotating rod 506 is fixedly connected to a driving gear 505. The left side of the U-shaped block 503 is fixedly connected to an electric telescopic rod 504.

[0042] The U-shaped block 503 facilitates the rotation of the driving gear 505, and the motor 502 can drive the trimming blade 605 to rotate through the driving gear 505 and the driven gear 501. The electric telescopic rod 504 can adjust the position of the driving gear 505, so as to facilitate the adjustment of the size of the trimming blade 605.

[0043] In another embodiment, if Figure 4 As shown, the electric telescopic rod 504 is fixedly connected to the right side of the U-shaped shell 1, a slide groove 508 is opened on the top of the U-shaped shell 1, a slider 507 is fixedly connected to the bottom of the U-shaped block 503, the slider 507 is slidably connected to the inner side of the slide groove 508, and the top of the transmission rod 606 is fixedly connected to the driven gear 501.

[0044] Under the action of the slide groove 508 and the slider 507 , the moving track of the U-shaped block 503 is limited, and at the same time, damage to the electric telescopic rod 504 under the action of external force is prevented.

[0045] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
