Description

Technical Field

[0001] This utility model relates to the field of horticultural machinery, specifically to a blower mechanism and an agricultural horticultural hedge trimmer. Background Technology

[0002] In the rapidly developing landscaping industry, hedge trimmers are an indispensable professional pruning tool. Their performance and efficiency directly affect the maintenance quality and cost-effectiveness of the landscape. Although traditional hedge trimmers can meet basic pruning needs in their design, their limitations gradually become apparent in actual use, especially when carrying out large-area, high-intensity pruning operations. Specifically, when a hedge trimmer performs planar pruning on tea trees, shrubs, park hedges, or roadside hedges, the high-speed rotation of the blades rapidly cuts off a large number of leaves. Due to inertia, these leaves often fall directly onto the cutting mechanism and its surrounding area, quickly accumulating. Over time, the accumulation of leaves increases, not only obstructing the operator's view and making it difficult for them to accurately judge the cutting position and adjust the pruning angle, but also potentially causing the cutting mechanism to become clogged, reducing its efficiency and even leading to mechanical failure. Furthermore, frequent leaf accumulation forces operators to interrupt pruning operations, move the hedge trimmer to an open area, and manually empty or clear the leaves. This process is not only time-consuming and labor-intensive, increasing the operator's workload, but also disrupts the continuity of pruning operations, reducing overall work efficiency. Therefore, we have made improvements, proposing a blower mechanism and an agricultural and horticultural hedge trimmer. Utility Model Content

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As described in the background section, when a hedge trimmer performs planar pruning on tea trees, shrubs, park hedges, or roadside hedges, the high-speed rotation of the blades quickly cuts off a large number of leaves. Due to inertia, these leaves often fall directly onto the cutting mechanism and its surrounding area, quickly accumulating. Over time, the amount of accumulated leaves increases, not only obstructing the operator's view and making it difficult for them to accurately judge the cutting position and adjust the pruning angle, but also potentially causing the cutting mechanism to reduce its efficiency due to leaf blockage, or even causing mechanical failure. In addition, frequent leaf accumulation forces the operator to interrupt the pruning operation, move the hedge trimmer to an open area, and manually dump or clean the leaves. This process is not only time-consuming and labor-intensive, increasing the operator's workload, but also disrupts the continuity of the pruning operation and reduces overall work efficiency.

[0020] To solve this technical problem, this utility model provides a blower mechanism and an agricultural and horticultural hedge trimmer.

[0021] For details, please refer to Figures 1-3 The blower mechanism specifically includes: The blower body 1 has a fixing structure 2 on it. The fixing structure 2 is used to install the blower body 1 onto the hedge trimmer. The fixing structure 2 includes a support part installed on the blower body 1. The support part has a limiting part. A clamp 3 is detachably connected between the limiting part and the support part. The clamp 3, the limiting part and the support part cooperate for the installation of the fixing structure 2.

[0022] The present invention provides a blower mechanism and an agricultural and horticultural hedge trimmer. The blower body 1, through its integrated blower mechanism, blows away the trimmed leaves during the trimming process. This achieves the function of real-time leaf dispersion during trimming, avoiding the problems of obstructed vision and frequent machine stops for cleaning caused by leaf accumulation. This means that operators can focus more on the trimming work itself without frequent interruptions to clean the leaves, thus greatly improving the continuity and overall efficiency of the trimming operation. By blowing away the leaves, the blower body 1 provides operators with an unobstructed view, enabling them to more accurately judge the cutting position and trimming height, thereby improving the aesthetics and consistency of the trimming effect. It also reduces the number of interruptions due to leaf cleaning, allowing the trimming operation to proceed continuously, significantly improving overall work efficiency. Operators no longer need to frequently move the hedge trimmer to displace the leaves.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1, please refer to Figures 1-3 The invention includes a blower body 1, a fixing structure 2 on which the blower body 1 is mounted to a hedge trimmer. The fixing structure 2 includes a support portion mounted on the blower body 1, a limiting portion, and a clamp 3 detachably connected between the limiting portion and the support portion. The clamp 3, the limiting portion, and the support portion cooperate for the installation of the fixing structure 2. Through the integrated blower body 1, this invention enables the real-time dispersion of trimmed blades during the trimming process, preventing blade accumulation. The problem of obstructed vision and frequent machine stops for cleaning caused by the accumulation of leaves means that operators can focus more on the pruning work itself without frequent interruptions to clean the leaves, thus greatly improving the continuity and overall efficiency of the pruning work. By blowing the leaves apart through the blower body 1, operators are provided with an unobstructed view, enabling them to more accurately judge the cutting position and pruning height, thereby improving the aesthetics and consistency of the pruning effect; reducing the number of times the work is interrupted due to cleaning the leaves, the pruning work can be carried out continuously, significantly improving the overall work efficiency, and operators do not need to frequently move the hedge trimmer to tilt the leaves.

[0027] Furthermore, such as Figure 3 As shown, the support includes a first fixed seat 201 fixedly installed on the blower body 1, and a second fixed seat 202 fixedly installed on the blower body 1.

[0028] Furthermore, such as Figure 1 As shown in the figure, the limiting part includes an internally threaded tube 203 fixedly installed on the second fixed seat 202. The inner wall of the internally threaded tube 203 is threadedly connected to a threaded rod 204. The clamp 3 is clamped between the threaded rod 204 and the first fixed seat 201. The clamp 3 can be pre-installed on the hedge trimmer. The blower body 1 can be installed on the hedge trimmer by clamping the clamp 3 with the threaded rod 204 and the first fixed seat 201. Rotating the threaded rod 204 separates the threaded rod 204 and the first fixed seat 201 from the clamp 3, and the blower body 1 can be removed. This makes the disassembly and assembly of the blower body 1 convenient and easy to inspect and clean.

[0029] Example 2, please refer to Figure 1 , Figure 2 and Figure 4 An agricultural horticultural hedge trimmer includes a blower mechanism and a hedge trimmer body 4. A handle 403 is fixedly connected to the outer surface of the hedge trimmer body 4, and a clamp 3 is fixedly sleeved on the outer surface of the handle 403. The handle 403 is used for hand gripping during operation.

[0030] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the main body 4 of the hedge trimmer is provided with a heat dissipation vent 401, and the heat dissipation vent 401 is positioned corresponding to the air inlet of the blower body 1. Heat dissipation vents 401 are provided on both sides of the main body 4 of the hedge trimmer to facilitate heat dissipation during use. Since the heat dissipation vent 401 and the air inlet of the blower body 1 are positioned corresponding to each other, the heat dissipation vent 401 and the blower body 1 can work together to increase the heat exchange between the main body 4 of the hedge trimmer and the outside world, so as to facilitate heat dissipation.

[0031] Furthermore, such as Figure 4 As shown, the main body 4 of the hedge trimmer also has a cutting blade 402. The air outlet of the blower body 1 corresponds to the position of the cutting blade 402, that is, the air blown out by the blower body 1 can clean up most of the blades accumulated on the cutting blade 402.

[0032] Example 3 further optimizes the agricultural and horticultural hedge trimmer provided in Example 2, specifically, as follows: Figure 1 , Figure 4 and Figure 5As shown, a protective mechanism 5 is provided between the main body 4 of the hedge trimmer and the cutting blade 402. The protective mechanism 5 is used to protect the cutting blade 402. The protection of the cutting blade 402 by the protective mechanism 5 can reduce the possibility of the cutting blade 402 accidentally injuring the staff or being damaged by bumps when being carried or stored. The protective mechanism 5 includes a fixed sleeve 501 fixedly installed on the side of the hedge trimmer body 4 near the cutting blade 402. The fixed sleeve 501 is fixedly connected to a connecting pipe 502, and the cutting blade 402 passes through the fixed sleeve 501 and the connecting pipe 502.

[0033] Furthermore, such as Figure 1 and Figure 5 As shown, a first protective cover 503 is inserted into the outer surface of the connecting pipe 502, and a second protective cover 504 is inserted into the inner wall of the first protective cover 503; the first protective cover 503 and the second protective cover 504 are located outside the cutting blade 402 to protect the cutting blade 402 and reduce damage to the cutting blade 402.

[0034] Furthermore, such as Figure 1 and Figure 5 As shown, the top of the first protective cover 503 is provided with a sliding groove 508, and a slider 505 is slidably connected in the sliding groove 508. One side of the slider 505 is fixedly connected to the second protective cover 504. A screw 506 is fixedly connected to the sliding groove 508, and a hand-tightening nut 507 is threadedly connected to the outer surface of the screw 506. The hand-tightening nut 507 is in contact with the first protective cover 503. The second protective cover 504 and the first protective cover 503 are designed to be retractable, so that the length can be shortened for easy storage after the second protective cover 504 and the first protective cover 503 are removed. The second protective cover 504 can be pushed and pulled after the hand-tightening nut 507 is loosened, and the position between the second protective cover 504 and the first protective cover 503 can be fixed after the hand-tightening nut 507 is tightened.

[0035] Furthermore, such as Figure 2 As shown, a buckle 509 is installed on the first protective cover 503, and a hook 510 that engages with the buckle 509 is fixedly installed on the fixing sleeve 501. The hook 510 and the buckle 509 cooperate with each other to fix the first protective cover 503 and the fixing sleeve 501.

[0036] The usage process of the blower mechanism and agricultural and horticultural hedge trimmer provided by this utility model is as follows: Unfasten the buckle 509 and the hook 510, then pull the first protective cover 503 to separate the first protective cover 503 and the hand-tightening nut 507 from the cutting blade 402. When using the blower body 1 to trim the blades, start the blower body 1 and blow air onto the cutting blade 402 to blow off the blades on the cutting blade 402 to prevent the blades from accumulating. After use, put the first protective cover 503 and the hand-tightening nut 507 on the outer surface of the cutting blade 402 so that the connecting pipe 502 is inserted into the first protective cover 503, and the hook 510 and the buckle 509 are fastened. When it is necessary to remove the blower body 1, rotate the threaded rod 204 to separate the threaded rod 204 from the clamp 3 to remove the blower body 1. During installation, align the threaded rod 204 and the first fixed seat 201 with the clamp 3, and rotate the threaded rod 204 to clamp the clamp 3 with the threaded rod 204 and the first fixed seat 201.
