Description

Technical Field

[0001] This utility model belongs to the field of planting technology, specifically a side branch pruning mechanism. Background Technology

[0002] Planting is the process of cultivating various crops, trees, fruit trees, flowers, medicinal plants, and ornamental plants by sowing the seeds in the soil. After some plants have grown a lot of branches and leaves, the excess branches and leaves need to be pruned to prevent them from affecting the plant's nutrient absorption.

[0003] Among them, a search revealed that application number CN202222020609.8, a pruning device with a collection structure for organic selenium-enriched tomato cultivation, features an adjustable distance between the receiving mechanism and the shears by adjusting the length of the electric telescopic column. This allows the operator to adjust the pruning of tomato seedlings according to their growth and the density of the foliage, making it relatively flexible in use. However, its shortcomings are as follows:

[0004] When staff use this organic selenium-enriched tomato planting collection structure pruning device to prune the planted tomato seedlings, the distance between the receiving mechanism and the shears can be adjusted by adjusting the length of the electric telescopic column. This allows the operator to adjust the pruning of the tomato seedlings according to their growth and the density of the branches and leaves. However, when adjusting the distance between the receiving mechanism and the shears, the fixed length of the shears makes it slightly inconvenient to prune some branches and leaves that are too far away for the staff to reach. Utility Model Content

[0019] 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.

[0020] In this utility model:

[0021] Example 1: Refer to Figure 1-4A side branch pruning mechanism includes a movable frame A1, a slide groove A101, a sliding frame A102, a movable frame B2, a mounting frame A3, a mounting frame B4, a cutter head 401, a mounting groove 402, and a handle 5. The movable frame B2 is rotatably mounted on the side of the movable frame A1 via a pivot. The slide groove A101 is embedded above both the movable frame A1 and the movable frame B2. The sliding frame A102 is slidably mounted inside the slide groove A101. A handle 5 is slidably mounted on the lower exterior of each sliding frame A102. A mounting frame B4 is mounted above each sliding frame A102. 4. An installation groove 402 is embedded below the sliding frame A102. An installation frame A3 is fixedly installed above the sliding frame A102 near the lower part of the installation frame B4, and the installation frame A3 is slidably set inside the installation groove 402. A cutter head 401 is fixedly installed obliquely to the side of the installation frame B4. A sliding pruning mechanism for quick and easy removal of side branches is provided on the outside of the movable frame A1 and movable frame B2. A limiting disassembly and assembly mechanism for easy replacement of the cutter head is provided on the outside of the installation frame A3. An adjustment mechanism for the length of the sliding frame A to remove side branches at a distance is provided above the handle 5.

[0022] Reference Figure 1-3 Furthermore, the sliding shearing mechanism is composed of a limiting groove A103, a sliding groove B104, a sliding frame B105, a damping telescopic rod A106, a limiting plate 107, and a limiting block A108.

[0023] Both movable frames A1 and B2 have limit grooves A103 embedded on their sides. A sliding groove B104 is embedded on the side of sliding frame A102. A sliding frame B105 is slidably mounted inside the sliding groove B104. A damping telescopic rod A106 is fixedly installed between the side of sliding frame B105 and the inner wall of the sliding groove B104, and a spring is fitted to the outside of the damping telescopic rod A106. A limit plate 107 is rotatably mounted on the side of sliding frame B105 via a bearing. A limit block A108 is fixedly mounted on the side of limit plate 107, and the limit block A108 is slidably fitted inside the limit groove A103. When workers plant several potato seedlings and they grow numerous side branches, and need to prune the excess side branches, pushing one of the limit plates 107 will cause the damping telescopic rod A106 and the outer spring to unfold, allowing the limit block A108 to slide out of the limit groove A103. 03. After the limit plate 107 is pushed to rotate on the outside of the sliding frame B105 via the bearing, one of the sliding frames A102 is released. The worker holds the handle 5 and pushes the two handles 5 in the opposite direction to drive the movable frame B2 and movable frame A1 to rotate through the shaft. This causes the side cutter head 401 of the mounting frame B4 to open. The worker places the cutter head 401 on both sides of the side branch to be pruned and pushes the two handles 5 to drive the movable frame B2 and movable frame A1 to rotate through the shaft. This causes the side cutter head 401 of the mounting frame B4 to close. At the same time, the cutter head 401 contacts both sides of the side branch, and pushes the released sliding frame A102 to slide repeatedly inside the slide groove A101. This causes one of the cutter heads 401 to slide repeatedly on the surface of the side branch, quickly cutting and removing the excess side branch. This makes it easy for the worker to prune the side branch and avoids the laborious effect of pruning some side branches with larger diameters.

[0024] Reference Figure 1 , 2 4. Furthermore, the limiting assembly and disassembly mechanism is composed of a limiting slot 301, a damping telescopic rod B302, a limiting block B303, a sliding groove C403, a limiting bracket 404, and a limiting groove C405.

[0025] Limiting slots 301 are embedded above and below the sides of mounting bracket A3, and the limiting slots 301 are L-shaped. Sliding grooves C403 are embedded above and below the sides of mounting bracket B4. A limiting bracket 404, also L-shaped, is slidably positioned between the sliding groove C403 and the inner side of the limiting slots 301. A limiting groove C405, arc-shaped, is embedded above the limiting bracket 404. A damping telescopic rod is fixedly installed on the upper inner wall of the limiting slots 301. B302, and a spring is provided on the outside of the damping telescopic rod B302. A limit block B303 is fixedly installed below the end of the damping telescopic rod B302, and the limit block B303 is slidably fitted inside the limit groove C405. When the staff prunes the excess side branches of several potato seedlings, if the cutter head 401 is damaged and needs to be replaced, the two damaged cutter heads 401 are pushed upward to release the side limit brackets 404 inside the limit groove 301, and then the two... The limit bracket 404 slides out of the limit slot 301 and the slide groove C403, and squeezes the limit block B303 to slide out of the limit slot C405, causing the damping telescopic rod B302 and the outer spring to retract. After releasing the mounting bracket B4, the worker pushes the mounting bracket B4 through the mounting groove 402 to remove it from the outside of the mounting bracket A3. After removing the cutter head 401, the worker slides the new cutter head 401 to the side of the mounting bracket B4 through the mounting groove 402 to the outside of the mounting bracket A3, and slides the two limit brackets 404 into the limit slots 301 and C403 respectively. Between the inner side of the slide groove C403 and the inner side of the slide groove C403, the pressing limit block B303 drives the damping telescopic rod B302 and the outer spring to retract, so that the limit bracket 404 slides completely into the limit slot 301. Then, the damping telescopic rod B302 and the outer spring pop out of the limit block B303 and slide into the inner side of the limit groove C405 to limit the limit bracket 404 and fix the cutter head 401, thus completing the replacement of the cutter head 401. This facilitates the disassembly and replacement of the cutter head 401 by the staff, so that the entire cutter head 401 does not need to be replaced when it is damaged.

[0026] Reference Figure 1 , 2 4. Furthermore, the length adjustment mechanism consists of a limiting groove B109, a sliding groove D501, a limiting frame 502, a damping telescopic rod C503, a groove 504, a push rod 505, and a telescopic rod 506.

[0027] A sliding frame A102 has several limiting grooves B109 embedded in its side, arranged equidistantly. A sliding groove D501 is embedded in the inner wall of the handle 5. A limiting frame 502 is slidably installed between the sliding groove D501 and the inner side of the limiting groove B109. A damping telescopic rod C503 is fixedly installed between the side of the limiting frame 502 and the inner wall of the sliding groove D501, and a spring is fitted on the outer side of the damping telescopic rod C503. A groove 504 is embedded above 502, and the lower part of the inner wall of the groove 504 is inclined. A push rod 505 is slidably installed between the upper part of the inner wall of the slide groove D501 and the inner side of the groove 504, and the lower part of the push rod 505 is inclined. A telescopic rod 506 is fixedly installed between the lower part of the push rod 505 and the lower part of the inner wall of the slide groove D501, and a spring is provided on the outer side of the telescopic rod 506. When the worker removes the excess side branches that have grown from the planted potato seedlings... When pruning, if some side branches are too far to be reached by the cutter head 401, the worker pushes the two push rods 505 to retract the telescopic rod 506 and the outer spring, and slides the limiting frame 502 out of the limiting groove B109 inside the groove 504, causing the damping telescopic rod C503 and the outer spring to retract. After releasing the handle 5, the worker pushes the handle 5 to slide outside the sliding frame A102, and after the sliding frame A102 is extended to the required length, the push rod 505 is released, causing the telescopic rod 506 and the outer spring to rebound the push rod 505. The damping telescopic rod C503 and the outer spring pop out of the limiting frame 502 and slide into one of the corresponding limiting grooves B109. After the handle 5 is limited, the worker holds the handle 5 and places the cutter head 401 on both sides of the side branches to prune the excess side branches. This allows the worker to freely adjust the length of the sliding frame A102, which is effective for pruning side branches that are far away. Example

[0028] like Figure 3 , 4As shown, in addition to the embodiment in which a groove 504 is embedded above the limiting frame 502 and the lower part of the inner wall of the groove 504 is inclined, and a push rod 505 is slidably disposed between the upper part of the inner wall of the slide groove D501 and the inner side of the groove 504, and the lower part of the push rod 505 is inclined, there is another embodiment in which a groove 504 is embedded above the limiting frame 502 and the lower part of the inner wall of the groove 504 is arc-shaped, and a push rod 505 is slidably disposed between the upper part of the inner wall of the slide groove D501 and the inner side of the groove 504. Furthermore, the push rod 505 is arc-shaped at the bottom. When the operator pushes the two push rods 505, the telescopic rod 506 and the outer spring will retract, resulting in a smaller contact area between the arc shape at the bottom of the push rod 505 and the arc-shaped inner wall of the groove 504, generating less friction. The sliding inside the groove 504 makes it easier to squeeze the limiting frame 502 out of the limiting groove B109, causing the damping telescopic rod C503 and the outer spring to retract, releasing the handle 5. Compared with the first embodiment, the length adjustment of the sliding frame A102 is easier and more convenient.

[0029] Working principle: First, the worker plants several potato seedlings, which grow numerous side branches. When the worker needs to prune the excess side branches, pushing one of the limiting discs 107 causes the damping telescopic rod A106 and the outer spring to unfold, allowing the limiting block A108 to slide out of the limiting groove A103. This pushes the limiting disc 107 to rotate outside the sliding frame B105 via the bearing, releasing one of the sliding frames A102. The worker then grasps the handle 5 and pushes both handles 5 in the opposite direction, causing the movable frame B2 and movable frame A1 to rotate via a pivot. This causes the side cutter head 401 of the mounting frame B4 to open. The worker then places the cutter head 401 on both sides of the side branch to be pruned and pushes the two handles 5 to move the movable frame B2 and movable frame A1 apart. By rotating the shaft, the side cutter head 401 of the mounting bracket B4 closes, causing the cutter head 401 to contact both sides of the side branch. Simultaneously, it pushes the released sliding bracket A102 to slide repeatedly inside the slide groove A101, causing one of the cutter heads 401 to slide repeatedly on the surface of the side branch, quickly cutting and removing excess side branches. If the cutter head 401 is damaged and needs replacement, the two damaged cutter head 401 side limit brackets 404 are pushed upwards and released inside the limit slot 301. This causes the two limit brackets 404 to slide out of the limit slot 301 and slide groove C403, and squeezes the limit block B303 out of the limit groove C405, causing the damping telescopic rod B302 and the outer spring to retract. After releasing the mounting bracket B4, the worker... The worker pushes the mounting bracket B4 through the mounting groove 402 to remove it from the outside of the mounting bracket A3. After removing the cutter head 401, the worker slides the new cutter head 401 side mounting bracket B4 through the mounting groove 402 to the outside of the mounting bracket A3. The worker then slides the two limit brackets 404 into the inner sides of the limit slots 301 and the slide groove C403, respectively. Squeezing the limit block B303 causes the damping telescopic rod B302 and the outer spring to contract, allowing the limit bracket 404 to slide completely into the limit slot 301. Then, the damping telescopic rod B302 and the outer spring pop out of the limit block B303 and slide into the inner side of the limit groove C405, limiting the limit bracket 404 and fixing the cutter head 401, thus completing the replacement of the cutter head 401. Finally, if some side branches are far away, the cutter head 401... When contact is not possible, the worker pushes the two push rods 505 to retract the telescopic rod 506 and the outer spring, and slides and squeezes the limiting frame 502 inside the groove 504 to slide out of the limiting groove B109, causing the damping telescopic rod C503 and the outer spring to retract. After releasing the handle 5, the worker pushes the handle 5 to slide outside the sliding frame A102, and after the sliding frame A102 is extended to the required length, the push rod 505 is released, causing the telescopic rod 506 and the outer spring to rebound the push rod 505. The damping telescopic rod C503 and the outer spring pop out of the limiting frame 502 and slide into one of the corresponding limiting grooves B109. After limiting the handle 5, the worker holds the handle 5 and places the cutter head 401 on both sides of the side branch to prune the excess side branch.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
