Description

Technical Field

[0001] The invention relates to the technical field of garden greening pruning, in particular to a pruning device used in garden greening projects. Background Art

[0002] Gardening and greening refers to the use of engineering technology and artistic means to create a beautiful natural environment and recreational environment within a certain area by transforming the terrain, planting plants, building buildings and arranging garden paths. Its main purpose is to make full use of the natural conditions of the city, cover the various types of gardens and green spaces at all levels in the city with garden plants with local characteristics and properties to the maximum extent, and form an organic system. However, given that plants will grow naturally over time, in order to ensure the continued beauty of the garden landscape and the health of the plant's morphology, it is particularly important to use professional pruning tools to finely prune the growing parts of the plants in a timely manner. This process not only maintains the neatness and ornamental nature of the plants, but is also an indispensable part of gardening and greening maintenance;

[0003] When staff are pruning landscaping, they usually directly bring the cutters on the pruning equipment into contact with the greenery. However, in the daily maintenance of landscaping, due to poor management of personnel or natural phenomena such as wind and rain, solid waste or dust from the outside is easily brought into the greening area and mixed between the branches of the greenery. The presence of solid waste or dust will increase the difficulty of pruning. When pruning, staff not only need to spend extra time and energy to clean up these impurities, thereby reducing the efficiency of pruning, especially when pruning dense shrubs or trees, the solid waste or dust mixed between the branches makes it difficult for the cutter to pass smoothly, increasing the resistance to pruning. In addition, the solid waste or dust contains hard particles, which will accelerate the wear of the cutter when in contact with the cutter of the pruning equipment, shortening the service life of the cutter. In addition, the accumulation of solid waste will also cause safety hazards. For example, during the pruning process, the cutter will bounce or deviate from the predetermined trajectory due to encountering hard particles, posing a threat to the staff.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a pruning device for landscaping engineering, which has the following beneficial effects:

[0020] 1. The pruning pretreatment mechanism can be used to pat the pruning part of the greenery back and forth before pruning the greenery, so as to knock down the solid garbage mixed between the greenery. This can not only make the subsequent pruning process of the horizontal cutting knife and the vertical cutting knife smoother, reduce the pruning resistance caused by impurities, make the pruning work easier, improve the pruning efficiency, and enable the staff to complete the pruning task faster, but also reduce the contact opportunities between the horizontal cutting knife and the vertical cutting knife and the hard particles, thereby extending the service life of the knife, reducing the frequency and cost of replacing the knife, and avoiding the horizontal cutting knife and the vertical cutting knife from bouncing or deviating from the predetermined trajectory due to contact with hard particles, posing a threat to the staff, thereby reducing such safety hazards and improving the safety of pruning work;

[0021] Among them, in the process of the longitudinal cleaning rod and the transverse cleaning rod reciprocatingly beating the untrimmed greenery, as the longitudinal cleaning rod and the transverse cleaning rod move horizontally toward the longitudinal cutting knife and the transverse cutting knife respectively, the greenery to be trimmed can be supported from the rear, which not only prevents the greenery from bending during the trimming process, making the greenery more stable, so that the cutter can better trim the greenery, and the trimming work can be carried out in a more stable environment, thereby improving the accuracy and safety of trimming, but also can disperse the pressure generated during the greening trimming process, avoid the greening part from being broken or damaged due to excessive force, help to protect the overall structure of the greening, ensure its healthy growth and beauty, and at the same time, can also help the trimmers better control the trimming force and angle, so as to obtain a more neat and beautiful trimming effect.

[0022] 2. By setting the first telescopic connecting plate, the second telescopic connecting plate, the sliding column and the lifting block, the horizontal cleaning rod and the longitudinal cleaning rod can be moved and adjusted synchronously with the horizontal cutting knife and the longitudinal cutting knife respectively, which not only ensures that the horizontal cleaning rod and the longitudinal cleaning rod can always be accurately aligned with the green part to be pruned during the pruning process, and effectively clean and support, thereby improving the coordination of the pruning work and making the pruning process smoother and more efficient. In addition, the synchronous movement reduces the pause and adjustment time during the pruning process, improves work efficiency, helps save manpower and time costs, and makes the landscaping maintenance work more efficient.

[0023] 3. Through the path obstacle clearing mechanism set up, the obstacles in front of the vehicle body, such as stones and solid garbage, can be cleared during the greening pruning process by driving the horizontal cutting knife and the longitudinal cutting knife to move the vehicle body, so as to prevent the stones and solid garbage from affecting the rollers of the vehicle body and causing the roller moving path to deviate. This not only ensures that the pruning tools can accurately prune along the predetermined trajectory, improves the neatness and beauty of greening pruning, and meets the high standards of garden greening maintenance, but also clears obstacles to avoid interruptions in the movement of the vehicle body, resulting in the suspending or changing of the direction of the pruning operation, thereby enabling the vehicle body to move continuously and stably, ensuring the continuity and integrity of the pruning operation.

[0024] 4. By setting the threaded rod, knob, horizontal plate, extension column and lifting column, the height of the cleaning brush can be changed when the greening is not trimmed, so that the cleaning brush is separated from the road surface, which can not only avoid the friction between the cleaning brush and the road surface, reduce unnecessary wear of the cleaning brush, thereby extending the service life of the cleaning brush, but also different road conditions require cleaning brushes of different heights for effective cleaning (such as slopes). By adjusting the height of the cleaning brush, it can adapt to more types of road conditions, thereby improving the versatility and practicality of the cleaning brush.

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0037] A pruning device for landscaping engineering of this embodiment, such as Figure 1 - Figure 7 As shown, it includes a vehicle body 1, a mounting frame 2 is fixedly connected to the upper end surface of the vehicle body 1, a lifting plate 3 is vertically slidably connected to the mounting frame 2, a transverse cutting knife 4 is fixedly connected to one side of the lifting plate 3, an extension plate 5 is slidably connected through the side of the upper end of the mounting frame 2 close to the transverse cutting knife 4, and a longitudinal cutting knife 6 is fixedly connected to the side of the extension plate 5 away from the mounting frame 2. It also includes a pruning pretreatment mechanism and a path obstacle cleaning mechanism. The pruning pretreatment mechanism includes a moving plate 701, a longitudinal cleaning rod 702 and a transverse cleaning rod 704. The moving plate 701 is slidably connected to the upper end surface of the vehicle body 1, and the pruning pretreatment mechanism is used to shake off the solid waste remaining between the greening before pruning the greening.

[0038] In this embodiment, Figure 1 and Figure 2 As shown, a vertical slot 707 is provided on one side of the movable plate 701 near the horizontal cleaning rod 704, and a lifting block 708 is slidably connected in the vertical slot 707. The horizontal cleaning rod 704 is fixedly connected to the side wall of the lifting block 708, and a second telescopic connecting plate 706 is fixedly connected between the lifting block 708 and the horizontal cutting knife 4. When the horizontal cutting knife 4 moves up and down, the lifting block 708 can be driven to move synchronously in the vertical slot 707 through the second telescopic connecting plate 706, thereby changing the position of the horizontal cleaning rod 704 connected to the side wall of the lifting block 708. When the movable plate 701 moves back and forth through the vertical slot 707 and the lifting block 708 to move the horizontal cleaning rod 704, the second telescopic connecting plate 706 connected between the lifting block 708 and the horizontal cutting knife 4 will shrink, thereby adapting to the position of the horizontal cleaning rod 704 and maintaining the connection between the horizontal cleaning rod 704 and the horizontal cutting knife 4.

[0039] In this embodiment, Figure 2 As shown, the movable plate 701 is symmetrically penetrated by sliding columns 705 for sliding connection, the longitudinal cleaning rod 702 is fixedly connected between the two sliding columns 705, the upper end of the longitudinal cleaning rod 702 is fixedly connected to a first telescopic connecting plate 703, and the first telescopic connecting plate 703 is fixedly connected to the longitudinal cutting knife 6 at one end away from the longitudinal cleaning rod 702. When the longitudinal cutting knife 6 moves horizontally, the longitudinal cleaning rod 702 can be driven to move synchronously through the first telescopic connecting plate 703 and the sliding column 705. When the movable plate 701 moves back and forth and moves the longitudinal cleaning rod 702 through the sliding column 705, the first telescopic connecting plate 703 connected between the longitudinal cleaning rod 702 and the longitudinal cutting knife 6 will shrink, so as to adapt to the position of the longitudinal cleaning rod 702 and maintain the connection between the longitudinal cleaning rod 702 and the longitudinal cutting knife 6.

[0040] In this embodiment, Figure 4As shown, a sliding groove 709 is provided at the center of the side of the movable plate 701 away from the vertical groove 707, a support plate 710 is fixedly connected to the side wall of the mounting frame 2, a driving motor 711 is fixedly connected to the support plate 710 away from the side of the movable plate 701, a driving shaft 712 is fixedly connected to the output end of the driving motor 711, the driving shaft 712 is rotatably connected to the support plate 710, a linkage plate 713 is fixedly connected to the end of the driving shaft 712 away from the driving motor 711, and a lever 714 is fixedly connected to the side of the linkage plate 713 close to the sliding groove 709. 714 is slidably connected in the slide groove 709. When the driving motor 711 is turned on to drive the driving shaft 712 to rotate on the support plate 710, the driving shaft 712 can drive the lever 714 to rotate with the driving shaft 712 as the center through the arranged linkage plate 713, and at the same time make the lever 714 slide back and forth in the slide groove 709. During the movement of the lever 714, the movable plate 701 will be driven to move back and forth on the upper end surface of the vehicle body 1 through the slide groove 709, so that the slide groove 709 on the movable plate 701 can follow the movement of the lever 714.

[0041] In the prior art, in the daily maintenance of gardening and greening, due to poor management by personnel or natural phenomena such as wind and rain, solid waste or dust from the outside is easily brought into the greening area and mixed between the branches of the greening. The presence of solid waste or dust will increase the difficulty of pruning. When pruning, the staff not only needs to spend extra time and energy to clean up these impurities, thereby reducing the efficiency of pruning. In particular, when pruning dense shrubs or trees, the solid waste or dust mixed between the branches makes it difficult for the cutter to pass smoothly, increasing the resistance to pruning. In addition, the solid waste or dust contains hard particles, which will accelerate the wear of the cutter when contacting with the cutter of the pruning equipment, shortening the service life of the cutter. In addition, the accumulation of solid waste will also cause safety hazards. For example, during the pruning process, the cutter will bounce or deviate from the preset direction due to contact with the hard particles. Compared with the prior art, before pruning the greenery, the pruning part of the greenery can be slapped back and forth to knock down the solid garbage mixed between the greenery, which can not only make the subsequent pruning process of the horizontal cutting knife 4 and the longitudinal cutting knife 6 smoother, but also reduce the pruning resistance caused by impurities, making the pruning work easier, improving the pruning efficiency, and enabling the staff to complete the pruning task faster, but also reduce the contact opportunities between the horizontal cutting knife 4 and the longitudinal cutting knife 6 and the hard particles, thereby extending the service life of the tool, reducing the frequency and cost of replacing the tool, and avoiding the horizontal cutting knife 4 and the longitudinal cutting knife 6 from bouncing or deviating from the predetermined trajectory due to encountering hard particles, posing a threat to the staff, thereby reducing such safety hazards and improving the safety of pruning work;

[0042] Among them, during the process of the longitudinal cleaning rod 702 and the transverse cleaning rod 704 reciprocatingly beating the untrimmed greenery, as the longitudinal cleaning rod 702 and the transverse cleaning rod 704 move horizontally toward the longitudinal cutting knife 6 and the transverse cutting knife 4 respectively, the greenery to be trimmed can be supported from the rear, which not only prevents the greenery from bending during the trimming process, making the greenery more stable, so that the tool can better trim the greenery, and the trimming work can be carried out in a more stable environment, thereby improving the accuracy and safety of trimming, but also can disperse the pressure generated during the greening trimming process, avoid the greening part from being broken or damaged due to excessive force, help protect the overall structure of the greening, ensure its healthy growth and beauty, and at the same time, can also help the trimmers better control the trimming force and angle, so as to obtain a more neat and beautiful trimming effect.

[0043] In other aspects, this embodiment also provides a path obstacle clearing mechanism for clearing obstacles in front of the vehicle body 1 that affect the moving path, such as Figure 1 , Figure 5 - Figure 7 As shown, the path obstacle cleaning mechanism includes a fixed plate 801, which is fixedly connected to the side wall of the vehicle body 1. The fixed plate 801 is symmetrically provided with through grooves 805, and moving blocks 806 are slidably connected in the through grooves 805. A cleaning brush 802 is arranged under the moving blocks 806.

[0044] In this embodiment, Figure 6 and Figure 7 As shown, the upper ends of the cleaning brushes 802 are fixedly connected with lifting columns 807, and the lifting columns 807 are all fixedly connected to the moving block 806. A horizontal plate 809 is arranged between the two lifting columns 807. The side of the horizontal plate 809 close to the lifting columns 807 is slidably connected with extension columns 812, and the ends of the extension columns 812 away from the horizontal plate 809 are fixedly connected to the lifting columns 807. When the horizontal plate 809 drives the lifting columns 807 to move up and down on the moving block 806 through the extension columns 812, the cleaning brush 802 connected to the lower end of the lifting columns 807 can be driven to move synchronously to change the height of the cleaning brush 802. When the moving block 806 drives the cleaning brush 802 to move back and forth horizontally through the lifting columns 807, the lifting columns 807 can pull the extension columns 812 to slide synchronously on the horizontal plate 809.

[0045] In this embodiment, Figure 6 As shown, a threaded rod 808 is threadedly connected through the center of the cross plate 809, and the threaded rod 808 is rotatably connected to the upper end surface of the fixed plate 801. A knob 810 is fixedly connected to the upper end of the threaded rod 808. When the knob 810 is rotated to drive the threaded rod 808 to rotate on the upper end surface of the fixed plate 801, the cross plate 809 can be driven to slide up and down on the outer surface of the threaded rod 808 through the threaded connection between the threaded rod 808 and the cross plate 809.

[0046] In this embodiment, Figure 5 and Figure 6 As shown, the upper end surface of the vehicle body 1 is horizontally slidably connected to a slider 804, and the upper end surface of the slider 804 is symmetrically rotatably connected to a connecting rod 811, and the end of the connecting rod 811 away from the slider 804 is rotatably connected to the side wall of the moving block 806. When the slider 804 reciprocates on the upper end surface of the vehicle body 1, it can drive one end of the connecting rod 811 to move synchronously, and push the moving block 806 to slide reciprocatingly in the through groove 805 through the connecting rod 811.

[0047] In this embodiment, Figure 5 As shown, the slider 804 is fixedly connected to a connecting frame 803 on one side away from the fixed plate 801, and the connecting frame 803 is fixedly connected to the side wall of the movable plate 701 on one end away from the slider 804. When the movable plate 701 slides back and forth on the upper end surface of the vehicle body 1, the connecting frame 803 can drive the slider 804 to reciprocate synchronously.

[0048] In the prior art, in the field of garden greening maintenance, mechanized pruning equipment has become a key tool to improve pruning efficiency and maintain the beauty of the garden. However, traditional greening pruning vehicles often face the problem of obstacle interference during operation. These obstacles (such as stones and solid garbage) not only hinder the rollers of the greening pruning vehicle, causing the roller moving path to deviate, thereby affecting the accuracy and neatness of pruning, but also the obstacles will cause the pruning operation to be interrupted, affecting the overall pruning effect and operation efficiency. With the continuous improvement of garden greening maintenance standards, higher requirements are put forward for pruning accuracy, beauty and operation continuity. Compared with the prior art, the system can be driven by the vehicle body 1 to move During the greening pruning process, the transverse cutting blade 4 and the longitudinal cutting blade 6 clear obstacles in front of the vehicle body 1, such as stones and solid garbage, to prevent the stones and solid garbage from affecting the rollers of the vehicle body 1 and causing the roller moving path to deviate. This not only ensures that the pruning tool can accurately prune along the predetermined trajectory, improves the neatness and beauty of greening pruning, and meets the high standards of garden greening maintenance, but also clears obstacles to prevent the vehicle body 1 from being interrupted during movement, causing the pruning operation to have to be suspended or changed direction, so that the vehicle body 1 can move continuously and stably, ensuring the continuity and integrity of the pruning operation;

[0049] By providing the threaded rod 808, knob 810, horizontal plate 809, extension column 812 and lifting column 807, the height of the cleaning brush 802 can be changed when the greenery is not trimmed, so that the cleaning brush 802 is separated from the road surface. This not only avoids friction between the cleaning brush 802 and the road surface and reduces unnecessary wear of the cleaning brush 802, thereby extending the service life of the cleaning brush 802, but also different road conditions require cleaning brushes 802 of different heights for effective cleaning (for example, slopes). By adjusting the height of the cleaning brush 802, it can adapt to more types of road conditions, thereby improving the versatility and practicality of the cleaning brush 802.

[0050] The working process and principle involved in the overall content of the above embodiment are as follows:

[0051] When the staff needs to trim the greenery, they first drive the lifting plate 3 to slide up and down on the mounting frame 2 to adjust the height of the transverse cutting knife 4 connected to the side wall of the lifting plate 3, and then drive the extension plate 5 to slide horizontally on the mounting frame 2 to adjust the distance between the extension plate 5 and the longitudinal cutting knife 6 connected to one side of the mounting frame 2 and the greenery. During the up and down movement of the transverse cutting knife 4, since the side wall of the transverse cutting knife 4 is connected with a second telescopic connecting plate 706, the second telescopic connecting plate 706 is fixedly connected to the lifting block 708, and the transverse cleaning rod 704 is fixedly connected to the lifting block 708, so as the transverse cutting knife 4 moves up and down, the second telescopic connecting plate 706 can drive the lifting block 708 to rise and fall synchronously in the vertical slot 707 opened on the side wall of the moving plate 701, and at the same time adjust the transverse cleaning rod 704. The height of the longitudinal cutting knife 6 is that during the movement of the longitudinal cutting knife 6, since the first telescopic connecting plate 703 is connected between the longitudinal cutting knife 6 and the longitudinal cleaning rod 702, and the longitudinal cleaning rod 702 is slidably connected to the movable plate 701 through the sliding column 705, the longitudinal cleaning rod 702 can be synchronously driven to move by the first telescopic connecting plate 703 as the longitudinal cutting knife 6 moves, which not only ensures that the transverse cleaning rod 704 and the longitudinal cleaning rod 702 can always accurately align with the green part to be pruned during the pruning process, and effectively clean and support it, thereby improving the coordination of the pruning work and making the pruning process smoother and more efficient, and the synchronous movement reduces the pause and adjustment time during the pruning process, improves the work efficiency, helps save manpower and time costs, and makes the garden greening maintenance work more efficient;

[0052] After the positions of the transverse cutting knife 4, the longitudinal cutting knife 6, the transverse cleaning rod 704 and the longitudinal cleaning rod 702 are adjusted, the staff can turn on the power of the transverse cutting knife 4 and the longitudinal cutting knife 6 to work, and at the same time turn on the driving motor 711 connected to the support plate 710 to drive the driving shaft 712 connected to the output end of the driving motor 711 to rotate synchronously. As the driving shaft 712 rotates, since the driving shaft 712 is connected to the end away from the driving motor 711 with a linkage plate 713, the linkage plate 713 is connected with a lever 714, and the lever 714 is slidably connected to the slide groove 709 opened on the side wall of the movable plate 701. Therefore, during the rotation of the driving shaft 712, the linkage plate 713 can be driven to drive the lever 714 to slide back and forth in the slide groove 709, and the lever 714 can drive the movable plate 701 to move horizontally back and forth on the vehicle body 1 through the slide groove 709. At this time, the movable plate 701 will pass through the vertical groove 707, lifting block 708 and slide column 705 drive the horizontal cleaning rod 704 and the longitudinal cleaning rod 702 to reciprocate synchronously. Before the horizontal cutting knife 4 and the longitudinal cutting knife 6 trim the greenery, the greenery is moved to knock down the solid garbage mixed between the greenery. This not only allows the horizontal cutting knife 4 and the longitudinal cutting knife 6 to pass more smoothly during the subsequent trimming process, reduces the trimming resistance caused by impurities, makes the trimming work easier, improves the trimming efficiency, and enables the staff to complete the trimming task faster, but also reduces the contact opportunities between the horizontal cutting knife 4 and the longitudinal cutting knife 6 and the hard particles, thereby extending the service life of the tool, reducing the frequency and cost of replacing the tool, and avoiding the horizontal cutting knife 4 and the longitudinal cutting knife 6 from bouncing or deviating from the predetermined trajectory due to encountering hard particles, posing a threat to the staff, thereby reducing such safety hazards and improving the safety of trimming work;

[0053] After the horizontal cleaning rod 704 and the longitudinal cleaning rod 702 hit the greening, the staff pushes the vehicle body 1 to move, driving the horizontal cutting knife 4 and the longitudinal cutting knife 6 to trim the greening. At this time, when the horizontal cleaning rod 704 and the longitudinal cleaning rod 702 are moving back and forth, they are close to the horizontal cutting knife 4 and the longitudinal cutting knife 6, and can support the greening to be trimmed from the rear, which not only prevents the greening from bending during the trimming process, but also makes the greening more stable, so that the cutter can better trim the greening, so that the trimming work can be carried out in a more stable environment, thereby improving the accuracy and safety of trimming, and can disperse the pressure generated during the trimming of the greening, avoiding the greening part from being broken or damaged due to excessive force, which is helpful to protect the overall structure of the greening, ensure its healthy growth and beauty, and at the same time, it can also help the trimmers to better control the trimming force and angle, so as to obtain a more neat and beautiful trimming effect;

[0054] When the movable plate 701 drives the horizontal cleaning rod 704 and the longitudinal cleaning rod 702 to process the greening, since the movable plate 701 is installed with a connecting frame 803 on the side close to the vehicle body 1, and the connecting frame 803 is connected with a slider 804 on the side away from the movable plate 701, and the slider 804 is slidably connected to the upper end surface of the vehicle body 1, as the movable plate 701 moves, the slider 804 can be driven to slide back and forth synchronously on the upper end surface of the vehicle body 1 through the connecting frame 803. At this time, the slider 804 will push the end of the connecting rod 811 symmetrically connected to the upper end to move, so that the connecting rod 811 pushes the movable block 806 rotatably connected to the end away from the slider 804 to slide back and forth in the through groove 805 opened on the fixed plate 801. In the process of the reciprocating movement of the slider 804, the through groove on the slider 804 The lifting column 807 connected by sliding connection can drive the extension column 812 to slide out and in reciprocatingly on the side wall of the horizontal plate 809, and at the same time, the cleaning brush 802 is moved to clean the path in front of the vehicle body 1 reciprocatingly, so as to remove obstacles in front of the vehicle body 1, such as stones and solid garbage, to prevent the stones and solid garbage from affecting the rollers of the vehicle body 1, causing the roller moving path to deviate, which not only ensures that the pruning tool can accurately prune along the predetermined trajectory, improves the neatness and beauty of greening pruning, and meets the high standards of garden greening maintenance, but also clears obstacles to avoid the vehicle body 1 from being interrupted during the movement, resulting in the pruning operation having to be suspended or changed direction, so that the vehicle body 1 can move continuously and stably, ensuring the continuity and integrity of the pruning operation;

[0055] When the transverse cutting knife 4 and the longitudinal cutting knife 6 have completed the trimming of the greenery, there is no need to maintain the stability of the moving path of the vehicle body 1. At this time, the staff can turn the knob 810 to drive the threaded rod 808 to rotate on the upper end surface of the fixed plate 801. Since the threaded rod 808 is threadedly connected to the transverse plate 809, the threaded rod 808 can drive the transverse plate 809 to rise and fall synchronously, and drive the lifting column 807 to slide upward on the moving block 806 synchronously through the extension column 812 slidably connected through both sides of the transverse plate 809, and pull the cleaning brush 802 connected to the lower end of the lifting column 807 to rise and separate from the road surface, which can avoid friction between the cleaning brush 802 and the road surface, reduce unnecessary wear of the cleaning brush 802, thereby extending the service life of the cleaning brush 802, and by adjusting the height of the cleaning brush 802, it can adapt to more types of road conditions, thereby improving the versatility and practicality of the cleaning brush 802.
