Description

Technical Field

[0001] The invention relates to the technical field of municipal engineering, and in particular to a hedge trimmer for highways. Background Art

[0002] A green belt is usually laid out in the middle of a highway to separate traffic in two directions, clearly display the inner edge, guide the driver's line of sight, eliminate arbitrary turns, and prevent vehicles traveling in opposite directions from colliding with each other at high speeds. At the same time, the green plants in the green belt need to be trimmed after a certain period of time to prevent the green plants from being too tall and blocking the driver's line of sight.

[0003] The existing hedge trimmers for small and medium-sized highways have fixed moving rollers during the trimming operation. When encountering a green belt on a curve, they need to be turned manually. At the same time, after trimming the excess branches and leaves on the green plants in the green belt, the existing hedge trimmers are usually not equipped with a cleaning device, so the trimmed branches and leaves will directly fall into the green belt. In windy weather, the trimmed branches and leaves are easily blown onto the highway, affecting driving safety. Therefore, it is urgent to design a hedge trimmer for highways that can be steered arbitrarily and can collect the trimmed branches and leaves. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, a highway hedge trimmer is provided which can turn arbitrarily and can collect and clean the trimmed branches and leaves.

[0005] The technical implementation scheme of the present invention is: a hedge trimmer for highways, comprising: a multi-stage telescopic rod, a locking pin, a workbench and a cutting knife, the multi-stage telescopic rod is provided with a locking pin, the tops of the multi-stage telescopic rods on the left and right sides are connected to the workbench, the cutting knives are installed on the workbench from left to right, and also comprises a moving device, a connecting plate, a micro motor, a pneumatic wheel, a collecting bin, a mounting plate, a fan, a connecting hose, a guide cover and a guide pipe, the bottoms of the multi-stage telescopic rods on the left and right sides are both installed with moving devices, and the moving devices on the left and right sides are both connected with connecting The connecting plates on the left and right sides are rotatably connected to pneumatic wheels at the rear, and a micro motor is also installed on the rear side of the connecting plate, and the output shaft of the micro motor is connected to the pneumatic wheel through a coupling, and the tops of the connecting plates on the left and right sides are connected to material collection bins, and the tops of the material collection bins on the left and right sides are commonly connected to a mounting plate, a fan is installed at the center of the mounting plate, the air inlet of the fan is connected to a connecting hose, the connecting hose is connected to a guide cover, the air suction part of the guide cover is connected to the workbench, the air outlet of the fan is connected to a guide pipe, and both ends of the guide pipe are respectively connected to the material collection bins on the left and right sides.

[0006] Optionally, at least three cutting knives are installed, and three cutting knives are installed on the workbench at intervals from left to right.

[0007] Optionally, the moving device is composed of a fixed block and universal wheels, the bottom of the multi-stage telescopic rod is connected to the fixed block, and the universal wheels are installed at intervals at the bottom of the fixed block.

[0008] Optionally, the connecting flow guide pipe is of a bending design, the middle part of the flow guide pipe is a bending part, and the middle part of the flow guide pipe is connected to the air outlet of the fan.

[0009] Optionally, it further includes a sliding block, a spring buckle and a guide wheel. The bottom of the multi-stage telescopic rod is slidably connected to the sliding block, a lock hole is provided at the bottom of the multi-stage telescopic rod, a spring buckle is provided in the lock hole, the inner side of the sliding block is rotatably connected to the guide wheel, and the spring buckle can cooperate with the sliding block. When the multi-stage telescopic rod is placed on both sides of the green belt, the sliding block can be adjusted to a height consistent with the green belt side rails. When the sliding block moves to the lock hole at this height, the spring buckle in the lock hole will directly pop into the groove of the sliding block to fix the sliding block at this height. At this time, the guide wheel on the sliding block contacts the outer side of the side rails on both sides of the green belt, which can make the movement smoother.

[0010] Optionally, it also includes a micro motor, an arc frame, a connecting block, a missing gear, a rack a, a broken tooth, a mounting block, a spur gear, a rack b and a buffer assembly. A micro motor is installed at the right edge of the top of the air deflector, and an arc frame is connected to the bottom of the air deflector. A connecting block is connected to the opposite side of the installation of the micro motor. The connecting block is rotatably connected with a missing gear, and the output shaft of the micro motor is connected with a missing gear through a coupling. Racks a are slidably connected to the left and right sides of the top of the air deflector, and the racks a on the left and right sides are respectively meshed with the missing gear on the connecting block and the missing gear on the micro motor. A broken tooth is commonly connected between the gears a on the left and right sides, mounting blocks are symmetrically connected to the left and right sides of the top of the air deflector, and spur gears are rotatably connected to the mounting block, and the spur gears are meshed with rack a. A buffer assembly is symmetrically installed on the bottom of the arc frame, and racks b are symmetrically slidably connected to the bottom of the air deflector, and the racks b on the left and right sides are respectively meshed with the spur gears symmetrically distributed on the left and right sides, and the rack a can contact the buffer assembly. When the fan sucks the trimmed branches and leaves into the air deflector, the micromotor on the air deflector will cause the missing gear to rotate when it is running. Since the missing gear is meshed with gear a, the micromotor drives the missing gear connected to its output shaft to rotate, which will cause gear a to slide downward. At this time, the bottom of rack a will squeeze the tension spring. When the missing gear rotates to an angle that is not meshed with rack a, the tension spring will lift up rack a when it loses resistance, so that it returns to its initial position. Then, when the missing gear rotates to an angle that meshes with rack a, rack a will slide down again, thereby achieving the effect of moving back and forth. Since there are crushing teeth between rack a, rack a will drive the crushing teeth to move together when it slides back and forth. At the same time, since rack a is meshed with the spur gear, rack a will cause rack b to move back and forth when it moves back and forth, so that the upper and lower crushing teeth can intermittently bite each other. When the upper and lower crushing teeth bite, the branches and leaves in the air deflector can be crushed, effectively preventing the trimmed branches and leaves from being too large and blocking the air deflector.

[0011] Optionally, the buffer assembly consists of a square block a, a square block b and a tension spring. The square block a is symmetrically connected to the bottom of the arc frame. The tension spring is connected to the square block a. The tension spring runs through the air deflector. The top of the tension spring is connected to the square block b, and the square block b is in contact with the rack a.

[0012] Optionally, it also includes a lower pressure plate, an L-shaped pull rod, a return spring, a connecting rod and a partition. The lower pressure plate is slidably connected in the aggregate bin, and the L-shaped pull rod is slidably connected on the aggregate bin. The bottom end of the L-shaped pull rod penetrates to the bottom of the aggregate bin and contacts with the bottom of the lower pressure plate. A return spring is provided between the bottom end of the L-shaped pull rod and the bottom of the aggregate bin. The top end of the L-shaped pull rod extends into the guide pipe, and the top end of the L-shaped pull rod is hinged with a connecting rod. A partition is rotatably connected to the middle part of the guide pipe, and one side of the partition is connected to the end of the connecting rod. When a lot of branches and leaves are collected in the left collection bin, the weight of the branches and leaves will cause the lower pressure plate to press down. When the lower pressure plate moves downward, it will squeeze the L-shaped pull rod and press the L-shaped pull rod down together. At the same time, the L-shaped pull rod will squeeze the reset spring. When the L-shaped pull rod is pressed down, it will drive the connection to move downward. At this time, the connecting rod will cause the partition connected to the guide pipe to rotate, thereby blocking the connection between the guide pipe and the left storage bin, so that the trimmed branches and leaves can only fall into the collection bin on the other side, effectively preventing imbalance caused by inconsistent weight of branches and leaves in the collection bins on both sides.

[0013] Optionally, a tool box is also included, the top of the connecting plate is connected to the tool box, the tool box corresponds to the aggregate bin, and the tool box can store the cutter head and some commonly used tools to prevent the cutter head from being difficult to find when it needs to be replaced when the storage position of the cutter head is different from that of the device.

[0014] Optionally, an observation window is provided on the aggregate bin, and the staff can check the accumulation of branches and leaves in the aggregate bin at any time through the observation window so as to clean them in time.

[0015] The beneficial effects of the present invention are: 1. The present invention has a movable device and a guide cover installed, and a universal wheel is connected to the bottom of the multi-stage telescopic rod. When encountering a bend, there is no need to disassemble it and the pruning operation can continue. Moreover, since the guide cover connected to the air inlet of the fan is facing the workbench, the cut branches and leaves will be sucked into the guide cover, and then enter the collection bin connected to the two sides of the guide pipe along the air outlet of the fan, so that the trimmed branches and leaves can be turned arbitrarily and collected and cleaned.

[0016] 2. The present invention installs a sliding block and a guide wheel. When the sliding block is adjusted to a height consistent with the green belt side rail, the spring clip in the lock hole will directly pop into the groove of the sliding block to fix the sliding block at this height. At this time, the guide wheel on the sliding block contacts the outer side of the side rails on both sides of the green belt, which can make the movement smoother. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0029] See also Figure 1-Figure 4A hedge trimmer for highways includes: a multi-stage telescopic rod 1, a locking pin 2, a workbench 3 and a cutting knife 4. The multi-stage telescopic rod 1 is provided with a locking pin 2. The tops of the multi-stage telescopic rods 1 on the left and right sides are connected to the workbench 3. The cutting knives 4 are installed on the workbench 3 from left to right. It also includes a moving device 5, a connecting plate 6, a micro motor 7, a pneumatic wheel 8, a collecting bin 9, a mounting plate 10, a fan 11, a connecting hose 12, a guide cover 13 and a guide pipe 14. The bottoms of the multi-stage telescopic rods 1 on the left and right sides are both installed with moving devices 5. The moving devices 5 on the left and right sides are both connected with connecting plates 6. The rear side of the connecting plate 6 is rotatably connected to a pneumatic wheel 8, and a micro motor 7 is also installed on the rear side of the connecting plate 6. The output shaft of the micro motor 7 is connected to the pneumatic wheel 8 through a coupling. The tops of the connecting plates 6 on the left and right sides are connected to collection bins 9, and the tops of the collection bins 9 on the left and right sides are commonly connected to a mounting plate 10. A fan 11 is installed at the center of the mounting plate 10, and a connecting hose 12 is connected to the air inlet of the fan 11, and a guide cover 13 is connected to the connecting hose 12. The air suction part of the guide cover 13 is connected to the workbench 3, and a guide pipe 14 is connected to the air outlet of the fan 11, and both ends of the guide pipe 14 are respectively connected to the collection bins 9 on the left and right sides.

[0030] At least three cutting knives 4 are installed, and three cutting knives 4 are installed on the workbench 3 at intervals from left to right.

[0031] The moving device 5 is composed of a fixed block and universal wheels. The bottom of the multi-stage telescopic rod 1 is connected to the fixed block, and the bottom of the fixed block is installed with universal wheels at intervals.

[0032] The connecting flow guide pipe 14 is of a bent design, the middle portion of the flow guide pipe 14 is a bent portion, and the middle portion of the flow guide pipe 14 is connected to the air outlet of the fan 11 .

[0033] When using the machine, first adjust the multi-stage telescopic rod 1 to the required height, and after adjusting the height, fix it with the locking pin 2, then place the machine on the small green belt in the middle of the highway, so that the multi-stage telescopic rods 1 on the left and right sides correspond to the siderails on both sides of the small green belt respectively, and then start the micro motor 7, the cutting knife 4 and the fan 11. When the micro motor 7 is in operation, the pneumatic wheel 8 connected to its output shaft will rotate, thereby driving the device to move along the siderail on the small green belt. At the same time, when the device moves, the cutting knife 4 on the multi-stage telescopic rod 1 will also rotate at a high speed, thereby being able to cut off the excess branches and leaves on the top of the green plants in the small green belt, so that the green plants can maintain a suitable height and at When constructing green plants on the green belt in the middle of the highway, since the bottom of the multi-stage telescopic rod 1 is connected to a universal wheel, pruning can be continued without removing it when encountering a curve. At the same time, when the cutting knife 4 on the workbench 3 cuts off excess branches and leaves, since the guide cover 13 connected to the air inlet of the fan 11 is facing the workbench 3, the cut branches and leaves will be sucked into the guide cover 13, and then enter the guide pipe 14 along the air outlet of the fan 11. Since the two sides of the guide pipe 14 are connected to the collection bin 9, the cut branches and leaves will fall into the collection bin 9. After pruning is completed, the machine can be turned off, thereby achieving the effect of being able to turn arbitrarily and collecting and cleaning the pruned branches and leaves.

[0034] See also Figure 5 , also includes a sliding block 15, a spring buckle 16 and a guide wheel 17. The sliding block 15 is slidably connected to the bottom of the multi-stage telescopic rod 1. A locking hole 151 is opened at the bottom of the multi-stage telescopic rod 1. The lock hole 151 is provided with a spring buckle 16. The inner side of the sliding block 15 is rotatably connected to the guide wheel 17, and the spring buckle 16 can cooperate with the sliding block 15.

[0035] When the multi-stage telescopic rod 1 is placed on both sides of the green belt, the sliding block 15 can be adjusted to a height consistent with the green belt side railing. When the sliding block 15 moves to the lock hole 151 at this height, the spring buckle 16 in the lock hole 151 will directly pop into the groove of the sliding block 15 to fix the sliding block 15 at this height. At this time, the guide wheels 17 on the sliding block 15 are in contact with the outer sides of the side rails on both sides of the green belt, which can make the movement smoother.

[0036] See also Figure 6 and Figure 7, also includes a micro motor 18, an arc frame 19, a connecting block 20, a missing gear 201, a rack a202, a broken tooth 203, a mounting block 204, a spur gear 205, a rack b206 and a buffer assembly 207. The micro motor 18 is installed at the right edge of the top of the air deflector 13, the bottom of the air deflector 13 is connected to the arc frame 19, the opposite side of the installation of the micro motor 18 is connected to the connecting block 20, the missing gear 201 is rotatably connected to the connecting block 20, the output shaft of the micro motor 18 is connected to the missing gear 201 through a coupling, the left and right sides of the top of the air deflector 13 are slidably connected to the rack a202, and the rack a202 on the left and right sides are connected to the rack a202. They are respectively meshed with the missing gear 201 on the connecting block 20 and the missing gear 201 on the micro motor 18, and a broken tooth 203 is commonly connected between the gears a on the left and right sides. The top left and right sides of the air deflector 13 are symmetrically connected with mounting blocks 204, and a spur gear 205 is rotatably connected to the mounting block 204, and the spur gear 205 is meshed with the rack a202. A buffer assembly 207 is symmetrically installed on the bottom of the arc frame 19, and a rack b206 is symmetrically slidably connected to the bottom of the air deflector 13, and the racks b206 on the left and right sides are respectively meshed with the spur gears 205 symmetrically distributed on the left and right, and the rack a202 can contact the buffer assembly 207.

[0037] The buffer assembly 207 is composed of a square block a, a square block b and a tension spring. The square block a is symmetrically connected to the bottom of the arc frame 19, and the tension spring is connected to the square block a. The tension spring runs through the air deflector 13, and the top of the tension spring is connected to the square block b, which is in contact with the rack a202.

[0038] When the fan 11 sucks the trimmed branches and leaves into the air deflector 13, the micro motor 18 on the air deflector 13 will cause the missing gear 201 to rotate. Since the missing gear 201 is meshed with the gear a, the micro motor 18 drives the missing gear 201 connected to its output shaft to rotate, which will cause the gear a to slide downward. At this time, the bottom of the rack a202 will squeeze the tension spring. When the missing gear 201 rotates to an angle that is not meshed with the rack a202, the tension spring will lift up the rack a202 when it loses resistance, restoring it to its initial position. Then, when the missing gear 201 rotates to the angle where it is meshed with the rack a202, the rack a202 will return to its original position. When the meshing angle is reached, rack a202 will slide downward again, thereby achieving the effect of moving back and forth. Since crushing teeth 203 are arranged between rack a202, rack a202 will drive crushing teeth 203 to move together when sliding back and forth. At the same time, since rack a202 is meshed with spur gear 205, rack a202 will cause rack b206 to move back and forth when moving back and forth, thereby making the upper and lower crushing teeth 203 intermittently engage with each other. When the upper and lower crushing teeth 203 engage, the branches and leaves in the air guide cover 13 can be crushed, effectively preventing the pruned branches and leaves from being too large and blocking the air guide cover 13.

[0039] See also Figure 8 , also includes a lower pressure plate 21, an L-shaped pull rod 22, a return spring 23, a connecting rod 24 and a partition 25. The lower pressure plate 21 is slidably connected in the collecting bin 9, and the L-shaped pull rod 22 is slidably connected on the collecting bin 9. The bottom end of the L-shaped pull rod 22 penetrates to the bottom of the collecting bin 9 and contacts with the bottom of the lower pressure plate 21. A return spring 23 is provided between the bottom end of the L-shaped pull rod 22 and the bottom of the collecting bin 9. The top end of the L-shaped pull rod 22 extends into the guide pipe 14, and the top end of the L-shaped pull rod 22 is hinged with a connecting rod 24. The middle part of the guide pipe 14 is rotatably connected with a partition 25, and one side of the partition 25 is connected to the end of the connecting rod 24.

[0040] When more branches and leaves are collected in the left collecting bin 9, the weight of the branches and leaves will cause the lower pressure plate 21 to be pressed down. When the lower pressure plate 21 moves downward, it will squeeze the L-shaped pull rod 22 and press the L-shaped pull rod 22 down together. At the same time, the L-shaped pull rod 22 will squeeze the return spring 23. When the L-shaped pull rod 22 is pressed down, it will drive the connection to move downward. At this time, the connecting rod 24 will cause the partition 25 rotatably connected to the guide pipe 14 to rotate, thereby blocking the connection between the guide pipe 14 and the left storage bin, so that the trimmed branches and leaves can only fall into the collecting bin 9 on the other side, effectively preventing the imbalance caused by inconsistent weight of branches and leaves in the collecting bins 9 on both sides.

[0041] See also Fig. 9 , also includes a tool box 26, the top of the connecting plate 6 is connected to the tool box 26, and the tool box 26 corresponds to the collecting bin 9.

[0042] The tool box 26 can store the cutter head of the cutting knife 4 and some commonly used tools, so as to prevent the cutter head of the cutting knife 4 from being difficult to find when the cutter head needs to be replaced when the storage position is different from that of the device.

[0043] See also Fig.10 , also includes an observation window 27, and the aggregate bin 9 is provided with an observation window 27.

[0044] The staff can check the accumulation of branches and leaves in the aggregate bin 9 at any time through the observation window 27 so as to clean them in time.
