Description
Technical Field
[0001] The invention belongs to the technical field of greening plant pruning equipment, and in particular relates to a mobile automatic pruning machine and a pruning method thereof. Background Art
[0002] With the development of society, people's requirements for living environment are increasing day by day, and the area of highway hedges and garden landscape greening is increasing. Green plants not only green the environment, but also eliminate visual fatigue and reduce traffic accidents.
[0003] Traditionally, handheld trimmers are mainly used to trim green plants. The handheld trimmers include a power transmission mechanism, a handle, and a blade mechanism. When working, the handheld trimmers are manually held, and the power transmission mechanism drives the blade mechanism to trim. When trimming with the handheld trimmers, workers need to hold the handheld trimmers to level them, which makes it difficult to trim evenly. Moreover, since the handheld trimmers are prone to vibration, workers need to hold the handles tightly to maintain balance, which results in high labor intensity. When trimming for too long, workers are prone to fatigue.
[0004] At present, there are some automatic trimmers for automatic trimming of green plants, for example, a hedge trimmer disclosed in Chinese invention patent application CN104488580A, which includes: a vehicle body; a chassis slewing device; a stationary arm support, one end of which is mounted on the chassis; a stationary arm, which is hinged on the other end of the stationary arm support; a lifting power member, which is arranged between the stationary arm and the stationary arm support, and is used to drive the stationary arm support to rotate around the hinge on the stationary arm; a movable arm, one end of which is sleeved on the stationary arm and can slide relative to the stationary arm; a cutter head assembly, which is installed on the other end of the movable arm. This invention can achieve horizontal trimming of hedges, but because its lifting power member adopts a hydraulic cylinder, due to the unevenness of the ground and the vibration of the equipment itself, the equipment will vibrate, thereby generating a large impact force on the hydraulic cylinder in a rigid state, resulting in a certain degree of skewness of the cutter head assembly during trimming of the horizontal plane, or the cutter head assembly deviates from the original set height. Because it lacks a monitoring device, it eventually leads to an uneven trimming plane, affecting the appearance.
[0005] In addition, when the hedge is trimmed horizontally, the height of the horizontal trimming surface is often manually visually estimated, resulting in inaccurate trimming height.
[0006] Therefore, in the field of green plant pruning equipment technology, there is still a need for research and improvement on automatic pruning machines and pruning methods thereof.

[0019] As an improvement, a counterweight box is further provided on the vehicle body between the driving cab and the operating cab.
[0020] In order to solve the second technical problem, the technical solution of the present invention is: a pruning method of a mobile automatic pruning machine, using the mobile automatic pruning machine, comprising the following steps:
[0021] An operator controls the rotary drive device, the arm oil cylinder, the arm oil cylinder and the cutter head assembly oil cylinder in the operating room, and under the drive of the rotary drive device, the rotary seat is rotated to rotate the cutter head assembly to a suitable angle;
[0022] Driven by the boom oil cylinder, the arm oil cylinder and the cutter head assembly oil cylinder, the height of the cutter head assembly is adjusted through the boom, the arm, the connecting rod and the rocker to make the mounting platform in a horizontal position or a vertical position. The driver operates the vehicle body to move, and with the movement of the vehicle body, the green plants are automatically trimmed in the plane or in the vertical direction.
[0023] When the mounting platform is in a horizontal position, the gravity hammer points to the horizontal indicator line. During the plane trimming process, the operator in the operating room can determine whether the cutter head assembly is skewed by observing whether the gravity hammer points to the horizontal indicator line. If the gravity hammer always points to the horizontal indicator line, it means that the trimming plane remains horizontal; if the gravity hammer deviates from the horizontal indicator line, it means that the trimming plane is skewed, and the vehicle body needs to stop moving and continue to move forward for trimming after adjusting the position.
[0024] After adopting the above technical solution, the beneficial effects of the present invention are:
[0025] The mobile automatic pruning machine and the pruning method provided by the present invention are designed with a vehicle body, a cab, a base, a slewing drive device, a slewing seat, an operating room, a big arm, a small arm, a connecting rod, a rocker, a cutter head assembly, a big arm oil cylinder, a small arm oil cylinder and a cutter head assembly oil cylinder; the cutter head assembly is designed with a mounting platform, a connecting arm and a plurality of pruning blades. Therefore, when in use, an operator controls the slewing drive device, the big arm oil cylinder, the small arm oil cylinder and the cutter head assembly oil cylinder in the operating room, and the slewing seat can be slewed under the drive of the slewing drive device, so that the cutter head assembly can be rotated to a suitable angle; under the drive of the big arm oil cylinder, the small arm oil cylinder and the cutter head assembly oil cylinder, the height of the cutter head assembly can be adjusted through the big arm, the small arm, the connecting rod and the rocker to make it in a horizontal position or a vertical position, so that the pruning posture can be adjusted conveniently; as the vehicle moves along, the operator can control the slewing drive device, the big arm oil cylinder, the small arm oil cylinder and the cutter head assembly oil cylinder. The movement of the body can realize automatic pruning of the plane or facade of green plants, with good pruning effect, flat and beautiful surface, replacing manual pruning, reducing the workload of workers and improving work efficiency; since the connecting arm is fixedly connected with a connecting rod parallel to the installation platform, a gravity hammer is rotatably installed on the free end of the connecting rod, and a horizontal indicator line is provided on the installation platform, when the installation platform is in a horizontal position, the gravity hammer points to the horizontal indicator line. In the process of pruning the green plants on the plane, the operator in the operation room can judge whether the cutter head assembly is skewed by observing whether the gravity hammer points to the horizontal indicator line. If the gravity hammer points to the horizontal indicator line, it means that the pruning plane remains horizontal; if the gravity hammer deviates from the horizontal indicator line, it means that the pruning plane is skewed, and the vehicle body needs to stop moving, and continue to move forward for pruning after adjusting the position.
[0026] Since the pruning cutter disc comprises a cutter disc body and a plurality of pruning blades fixedly mounted on the cutter disc body and arranged in a circular array, the pruning efficiency of the pruning cutter disc is higher, and the time for replacing the pruning blades is also extended, making the pruning cutter disc durable.
[0027] Since a plurality of protective teeth arranged at intervals are fixedly installed on one side of the mounting platform close to the pruning cutter disc, the protective teeth can pre-remove debris on the pruning surface during operation, thereby effectively protecting the pruning cutter disc; since a protective cover is also designed on the mounting platform, the pruning cutter disc is effectively protected.
[0028] Since a reinforcing plate is provided on the side of the mounting platform away from the pruning blade, the strength of the mounting platform is improved.
[0029] Since the first column, fixing nut, fixing plate, arc scale line, screw, disc, scale line pointer, first laser pen, first sleeve and first fastener are designed on the frame of the operating room, before pruning, when the mounting platform is adjusted to the required horizontal position, the disc is rotated to drive the screw, the first sleeve and the first laser pen to rotate, so that the light spot emitted by the first laser pen is irradiated to a fixed position on the cutter head assembly, and the angle indicated by the scale line pointer on the arc scale line is recorded; when pruning the horizontal surface of the green plant, the operator can randomly turn on the first laser pen to observe whether the light spot emitted by the first laser pen is irradiated to the fixed position on the cutter head assembly. If so, it means that the cutter head assembly is still at the set height; if not, it means that the cutter head assembly is out of the set height. At this time, the vehicle body needs to stop moving forward, and after the position is adjusted, it continues to move forward for pruning.
[0030] Since the fixing nut is also provided with a first locking assembly, the screw rod can be effectively prevented from rotating through the first locking assembly; since a locking nut portion is provided on the side wall of the fixing nut, the first locking assembly includes a locking rod and an operating handle fixed to the outer end of the locking rod, and the inner end of the locking rod passes through the side wall of the fixing nut and abuts against the screw rod, so that when the disc needs to be rotated, the locking rod is loosened by rotating the operating handle; when the first laser pen is rotated into place, the operating handle is rotated in the reverse direction to make the locking rod press against the screw rod to prevent the first laser pen from rotating due to factors such as vibration during trimming.
[0031] Since the vehicle body is also designed with a second column, a vertical scale, a second locking assembly, an adjustment sleeve, a scale pointer, a second laser pen, a second sleeve and a second fastener, before pruning, the second locking assembly is loosened, the adjustment sleeve is moved along the second column to make the scale pointer point to the set height on the vertical scale, the second laser pen is turned on, and the height of the cutter head assembly is adjusted by the hydraulic drive device so that the light spot emitted by the second laser pen is irradiated onto the pruning disc of the cutter head assembly, thereby realizing accurate determination of the trimming height of the cutter head assembly.
[0032] In summary, the mobile automatic trimming machine and the trimming method provided by the present invention replace manual labor and realize automatic trimming of green plants in plane or elevation. It has a high degree of automation, good trimming effect, flat and beautiful surface, reduces the workload of workers and improves work efficiency. At the same time, it realizes the monitoring of the cutter head assembly to ensure that it does not tilt or deviate from the set height when trimming the horizontal plane, and realizes the precise determination of the trimming height of the cutter head assembly.

[0049] like Figures 1 to 5As shown together, a mobile automatic trimmer includes a body 1, a cab 29 is provided on the front side of the body 1, a base 30 is fixedly installed or integrally provided on the body 1 located behind the cab 29, a swivel seat 2 driven by a swivel drive device (not shown in the figure) is rotatably installed on the base 30, an operating room 3 is provided on the swivel seat 2, one end of a large arm 4 is hinged on the swivel seat 2 located on one side of the operating room 3, the other end of the large arm 4 is hinged to one end of a small arm 5, the other end of the small arm 5 is respectively hinged to a rocker 6 and a cutter head assembly 7, the rocker 6 is hinged to one end of a connecting rod 8, the other end of the connecting rod 8 is hinged to the cutter head assembly 7, the cutter head assembly 7 includes a mounting platform 711, a connecting arm 712 arranged perpendicular to the mounting platform 711 and hinged to the small arm 5, and two pruning shear discs 72 rotatably installed on the mounting platform 711 and arranged at intervals. Of course, the number of the pruning shear discs 72 is not limited to two, and can also be three, four, and so on.
[0050] A driving motor 73 and a transmission box 74 are also provided on the mounting platform 711. The output shaft of the driving motor 73 is connected to the input end of the transmission box 74. The transmission box 74 has a plurality of output ends (not shown in the figure). The number of the output ends is consistent with the number of the trimming shear discs 72. In this embodiment, there are two output ends, and each output end is connected to a trimming shear disc 72. Specifically, a chain transmission device 741 is used in the transmission box 74 for transmission. Of course, as an alternative, a belt transmission device or the like may also be used in the transmission box 74, which is well known to those skilled in the art and will not be described in detail here.
[0051] It should be noted that the above-mentioned rotary drive device is preferably a hydraulic motor. Of course, other methods that can be implemented by those skilled in the art may also be selected, such as electric motors, etc., which are well known to those skilled in the art and will not be described in detail here.
[0052] The mobile automatic trimmer also includes an upper arm cylinder 9, an arm cylinder 10 and a cutter head assembly cylinder 11. One end of the upper arm cylinder 9 is hinged to the swivel seat 2, and the other end is hinged to the upper arm 4; one end of the arm cylinder 10 is hinged to the upper arm 4, and the other end is hinged to the arm 5; one end of the cutter head assembly cylinder 11 is hinged to the arm 5, and the other end is hinged to the hinge point of the connecting rod 8 and the rocker 6.
[0053] In a specific implementation of the embodiment of the present invention, Figure 2 and Figure 3 The trimming cutter disc 72 includes a cutter disc body 721 and a plurality of trimming blades 722 fixedly mounted on the cutter disc body 721 and arranged in a circular array. In the present embodiment, three trimming blades 722 are selected. Of course, the number of trimming blades 722 can also be two, four, etc., which will not be repeated here. This makes the trimming efficiency of the trimming cutter disc 72 higher, and also prolongs the time for replacing the trimming blades 722, making the trimming cutter disc 72 durable.
[0054] In a specific implementation of the embodiment of the present invention, Figure 2 , Figure 3 and Figure 6 As shown together, a plurality of protective teeth 713 arranged at intervals and a protective cover 714 for protecting the pruning blade 72 are fixedly installed on one side of the mounting platform 711 close to the pruning blade 72. The protective teeth 713 can remove debris on the pruning plane in advance during operation, thereby effectively protecting the pruning blade 72.
[0055] In a specific implementation of the embodiment of the present invention, Figure 2 , Figure 4 and Figure 6 As shown together, in order to improve the strength of the mounting platform 711 , a reinforcing plate 715 is further provided on the side of the mounting platform 711 away from the trimming blade 72 .
[0056] A connecting rod 716 parallel to the mounting platform 711 is fixedly connected to the connecting arm 712, a gravity hammer 717 is rotatably mounted on the free end of the connecting rod 716, a horizontal indicator line 718 is provided on the mounting platform 711, and when the mounting platform 711 is in a horizontal position, the gravity hammer 717 points to the horizontal indicator line 718.
[0057] When in use, the operator controls the slewing drive device, the boom cylinder 9, the arm cylinder 10 and the cutter head assembly cylinder 11 in the operating room 3. Driven by the slewing drive device, the slewing seat 2 can be rotated, so that the cutter head assembly 7 can be rotated to a suitable angle; driven by the boom cylinder 9, the arm cylinder 10 and the cutter head assembly cylinder 11, the height of the cutter head assembly 7 is adjusted by the boom 4, the arm 5, the connecting rod 8 and the rocker 6 to be in a horizontal position or a vertical position, so that the trimming posture can be adjusted conveniently; the driver operates the vehicle body 1 to move, and as the vehicle body 1 moves, the green plants can be automatically trimmed in plane or elevation, with good trimming effect, flat and beautiful surface, replacing manual trimming, reducing the workload of workers and improving work efficiency. When the mounting platform 711 is in a horizontal position, the gravity hammer 717 points to the horizontal indicator line 718. During the flat trimming of green plants, the operator in the operating room 3 can determine whether the cutter head assembly 7 is skewed by observing whether the gravity hammer 717 points to the horizontal indicator line 718. If the gravity hammer 717 points to the horizontal indicator line 718, it means that the trimming plane remains horizontal; if the gravity hammer 717 deviates from the horizontal indicator line 718, it means that the trimming plane is skewed, and the vehicle body 1 needs to stop moving and continue to move forward for trimming after adjusting the position.
[0058] In a specific implementation of the embodiment of the present invention, in order to ensure that the cutter head assembly 7 is at a set height during the trimming process, such as Figure 1 , Figure 7 , Figure 8 and Fig. 9 As shown together, a first column 12 is provided on the frame of the operating room 3, and an axially horizontally arranged fixing nut 13 is provided on the top of the first column 12. A fixing plate 14 is fixedly connected to one side of the fixing nut 13, and an arc scale line 15 is provided on the fixing plate 14. A screw 16 is threadedly connected to the fixing nut 13, and a disc 17 is fixedly connected to one end of the screw 16 close to the fixing plate 14, and a scale line pointer 18 is provided on the disc 17. The other end of the screw 16 is fixedly connected to a first sleeve 19 for placing a first laser pen (not shown in the figure), and a first fastener for fixing the first laser pen is provided on the first sleeve 19. The first fastener is preferably a bolt 20, and of course, screws and the like can also be selected, which will not be repeated here; the bolt 20 is arranged along the radial direction of the first sleeve 19.
[0059] In this way, before pruning, when the mounting platform 711 is adjusted to the required horizontal position, the disc 17 is rotated, thereby driving the screw 16, the first sleeve 19 and the first laser pen to rotate, so that the light spot emitted by the first laser pen is irradiated to a fixed position on the cutter head assembly 7, and the angle indicated by the scale pointer 18 on the arc scale line 15 is recorded; when pruning the horizontal surface of the green plants, the operator can randomly turn on the first laser pen to observe whether the light spot emitted by the first laser pen is irradiated at the fixed position on the cutter head assembly 7. If so, it means that the cutter head assembly 7 is still at the set height; if not, it means that the cutter head assembly 7 is out of the set height. At this time, the vehicle body 1 needs to stop moving forward, and after adjusting the position, continue to move forward for pruning.
[0060] In a specific implementation of an embodiment of the present invention, in order to prevent the screw 16 from rotating, a first locking component 21 is also provided on the fixing nut 13, and a locking nut portion 131 is provided on the side wall of the fixing nut 13. The first locking component 21 includes a locking rod 211 threadedly connected to the locking nut portion 131 and an operating handle 212 fixed to the outer end of the locking rod 211. The inner end of the locking rod 211 passes through the side wall of the fixing nut 13 and abuts against the screw 16.
[0061] In this way, when the disc 17 needs to be rotated, the locking rod 211 loosens the screw 16 by rotating the operating handle 212; when the first laser pen is rotated to the right position, the operating handle 212 is rotated in the opposite direction to make the locking rod 211 press against the screw 16 to prevent the first laser pen from rotating due to factors such as vibration during trimming.
[0062] In a specific implementation of the embodiment of the present invention, in order to accurately determine the trimming height of the cutter head assembly 7, as shown in FIG. Figure 1 , Fig.10 and Fig.11As shown together, a second column 22 is also fixedly mounted on the vehicle body 1, a vertical scale 23 is fixedly mounted on the second column 22, an adjusting sleeve 25 is fixedly mounted on the second column 22 via a second locking assembly 24, the structure of the second locking assembly 24 is similar to that of the first locking assembly 21, and will not be described in detail here; the adjusting sleeve 25 is respectively provided with a scale pointer 26 and a second sleeve 27 for placing a second laser pen (not shown in the figure) and arranged horizontally, the second sleeve 27 is radially provided with a second fastener for fixing the second laser pen, the second fastener is preferably a bolt 28, of course, screws, etc. can also be selected, and will not be described in detail here.
[0063] In this way, before pruning, the second locking assembly 24 is loosened, the adjusting sleeve 25 is moved along the second column 22, so that the scale pointer 26 points to the set height on the vertical scale 23, the second laser pen is turned on, and the height of the cutter head assembly 7 is adjusted by the upper arm cylinder 9, the lower arm cylinder 10 and the cutter head assembly cylinder 11, so that the light spot emitted by the second laser pen is irradiated onto the pruning blade 72 of the cutter head assembly 7, thereby realizing the accurate determination of the pruning height of the cutter head assembly 7.
[0064] In a specific implementation of the embodiment of the present invention, Figure 1 As shown, in order to maintain the front and rear balance of the vehicle body 1, a counterweight box 31 is also provided on the vehicle body 1 between the cab 29 and the operating room 3.
[0065] The embodiment of the present invention further discloses a pruning method using a mobile automatic pruning machine, which uses the mobile automatic pruning machine and comprises the following steps:
[0066] The operator controls the rotary drive device, the arm cylinder 9, the arm cylinder 10 and the cutter head assembly cylinder 11 in the operating room 3, and the rotary seat 2 is rotated under the drive of the rotary drive device to rotate the cutter head assembly 7 to a suitable angle;
[0067] Driven by the boom cylinder 9, the arm cylinder 10 and the cutter head assembly cylinder 11, the height of the cutter head assembly 7 is adjusted through the boom 4, the arm 5, the connecting rod 8 and the rocker 6, and the mounting platform 711 is placed in a horizontal position or a vertical position. The driver operates the vehicle body 1 to move, and with the movement of the vehicle body 1, the green plants are automatically trimmed in the plane or in the vertical direction.
[0068] When the mounting platform 711 is in a horizontal position, the gravity hammer 717 points to the horizontal indicator line 718. During the plane trimming process, the operator in the operating room 3 can determine whether the cutter head assembly 7 is skewed by observing whether the gravity hammer 717 points to the horizontal indicator line 718. If the gravity hammer 717 always points to the horizontal indicator line 718, it means that the trimming plane remains horizontal; if the gravity hammer 717 deviates from the horizontal indicator line 718, it means that the trimming plane is skewed, and the vehicle body 1 needs to stop moving and continue to move forward for trimming after adjusting the position.
