Description

Technical Field

[0001] The invention relates to a lawn mowing device and a lawn mowing method for greening construction, belonging to the technical field of garden greening. Background Art

[0002] The hedge shears are one of the commonly used equipment for mowing grass. The hedge shears are suitable for plants with thicker and harder branches. The hedge shears include a movable blade holder and a fixed blade holder. The movable blade holder and the fixed blade holder produce relative movement, so that the blade head on the movable blade holder cooperates with the blade head on the fixed blade holder to achieve grass mowing. The maximum spacing between the blade head on the movable blade holder and the blade head on the fixed blade holder is fixed. At the same time, the blade head is a V-shaped structure. When the branch stem of the plant is thicker, the branch stem cannot enter between the two matching blade heads, and only the head of the blade head is in contact with the branch stem. When the spacing between the two matching blade heads is reduced, the blade head will move away from the branch stem relative to the branch stem. Only a part of the branch stem can be cut off at a time, and multiple repeated horizontal movements are required to gradually cut off the branch stem. During the multiple horizontal movements, because the hedge shears are controlled by people, the hedge shears cannot be kept at the same level, so there will be deviations in the shearing position of each branch stem, which slows down the cutting speed of the thick branch stem, thereby affecting the pruning efficiency. Summary of the invention

[0005] Specifically, the cam mechanism includes a connecting plate, one end of the fixed tool holder is connected and fixed with a U-shaped frame, a connecting plate is slidably installed in the space formed by the U-shaped frame and the fixed tool holder, one end of the connecting plate is connected and fixed to the movable tool holder, the connecting plate is rotatably connected with a crank away from the movable tool holder, the end of the crank away from the connecting plate is rotatably installed with a driving wheel for installation on the output shaft of the motor, and a side surface of the U-shaped frame is installed with a connecting seat for installation on the surface of the shell.

[0006] The transmission gear of the present invention is a gear selected from the group consisting of a plurality of gears, a plurality of gears having respective engagement with the gears of the respective motor and a plurality of gears coupled to the gears of the respective motor.

[0007] Specifically, both ends of the support plate are connected and fixed with L-shaped plates, a pad connected and fixed to the shell cover is provided between the L-shaped plate and the shell cover, the connecting screw passes through the L-shaped plate and is threadedly connected to the pad, and two axial holes matching the transmission shaft are provided on the support plate, the transmission shaft passes through the axial holes and the transmission shaft is rotatably connected to the support plate.

[0008] The cam is an axially coupled machine which is adapted to engage the second end of the chain and to engage with the second end of the chain so that the cam can move relative to the first end of the chain.

[0009] Specifically, a movable gear connected and fixed to the column rod is sleeved on one end of the column rod close to the blocking cover, and a secondary needle head is connected and fixed to the end of the pin away from the sliding block. The secondary needle head is an L-shaped structure, and racks meshing with the movable gear are installed on the two second arm plates, and a weight-reducing opening is opened on one side of the rack.

[0010] Specifically, both sides of the circular hole along the length direction of the column are provided with slip rings, the slip rings are in sliding contact with the ears, and the slip rings are sleeved on the column and fixedly connected with the column.

[0011] Specifically, both ends of the strip shell are connected and fixed with connecting edges, a convex edge is provided between the strip shell and the fixed tool holder, the convex edge is connected and fixed to the fixed tool holder, a connecting edge of the strip shell close to the convex edge is connected to the convex edge by multiple screws, a connecting edge of the strip shell away from the convex edge is connected to the shell cover by multiple screws, and one end of the second support arm plate is connected and fixed to the convex edge.

[0012] A mowing method for greening construction comprises the following steps: Step 1: First, the first blade head and the second blade head on the fixed blade holder and the movable blade holder cooperate with each other to cut and remove the branches around the thicker branches, and retain the thicker branches; Step 2: Then place the thicker branch rod between the two second chains; Step 3: Move the structure formed by the fixed tool holder and the movable tool holder toward the branch with a larger thickness, so that the pins on the two second chains penetrate into the branch with a larger thickness, and as the second chain rotates, the branch with a larger thickness moves toward the first blade head and the second blade head.

[0013] Beneficial effects of the present invention: 1. The movable tool holder drives the shifting teeth to move through the positioning plate. When the shifting teeth move in the direction away from the U-shaped frame, the inner wall of the rectangular groove limits the rotation of the shifting teeth, so that the relative positions of the plurality of shifting teeth and the positioning plate remain unchanged. At this time, the shifting teeth mesh with the driving gear and drive the driving gear to rotate. Under the transmission of the two driven gears and the two intermediate gears, the two driving sprockets rotate towards each other. Under the transmission of the first chain, the driven sprocket and the two synchronous sprockets rotate. At this time, the second chain rotates around the synchronous sprocket and the reversing sprocket. At this time, multiple groups of pins move with the corresponding second chain to provide power for the movement of the pins. There is no need to add a power source to drive the pins to move. When the shifting teeth move in the direction close to the U-shaped frame, the shifting teeth rotate, thereby not providing driving force to the driving gear.

[0014] 2. Place the thicker branch between the two second chains, and insert the pins on the two second chains into the branch between the two second chains. Under the restriction of the pins and the second chain, move the branch toward the first cutter head and the second cutter head. When the distance between the first cutter head and the second cutter head is reduced, the first cutter head and the second cutter head will not move away from the branch. There is no need to repeat the horizontal movement to gradually cut the branch, so that the cutting speed of the thick branch becomes faster, thereby improving the pruning efficiency of the thicker branches.

[0015] 3. Install one end of the pin with the sliding block in the rectangular cavity of the column rod, and install a spring between the sliding block and the plug cover. When the pin is subjected to the reaction force of the branch rod, the pin drives the sliding block to squeeze the spring, causing the spring to produce elastic deformation, thereby achieving the effect of buffer protection.

[0016] 4. When the column rotates, the structure formed by the insertion pin and the auxiliary needle head also rotates. When the moving gear on the column engages with the rack, driven by the second chain, the moving gear moves along the length direction of the rack and rotates, causing the structure formed by the insertion pin and the auxiliary needle head to rotate. Then, the rotating auxiliary needle head realizes the drilling operation on the branch, and realizes the early damage of the thicker branch, so that the thickness of the branch moved to the first cutter head and the second cutter head becomes smaller, thereby sharing the workload of the first cutter head and the second cutter head, which is beneficial to reduce the wear of the first cutter head and the cutter head, and extend the service life of the first cutter head and the second cutter head.

[0017] 5. The structure formed by the shell cover and the strip shell plays the role of hiding the driving gear, the intermediate gear and the driven gear, and at the same time provides a support carrier for the driving sprocket, etc. When the branch rod moves to the strip shell driven by the second chain, the branch rod will be separated from the insertion pin and the auxiliary needle head under the joint action of the blocking of the strip shell and the continued rotation of the second chain, thereby removing the branch rod from the insertion pin and the auxiliary needle head.

[0018] 6. When using screws to connect the support plate and the shell cover, align the two L-shaped plates on the support plate with the gaskets respectively, and then pass the connecting screws through the L-shaped plates and connect them with the gasket threads to complete the assembly of the support plate and the shell cover, thereby partially increasing the thickness of the shell cover where the support plate is installed. The support plate and the shell cover jointly achieve two-point support for the drive shaft, thereby improving the stability of the structure.

[0019] 7. Install a convex edge on the fixed tool holder, and use multiple sets of screws to connect the convex edge and the connecting edge to complete the assembly of the strip shell and the fixed tool holder, thereby increasing the thickness of the strip shell portion where the fixed tool holder is installed, and at the same time, connect and fix one end of the second arm plate to the convex edge to improve the stability of the connection between the second arm plate and the fixed tool holder.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1: When the branches of plants are thick, the branches cannot enter between the two matching V-shaped blade heads, and only the heads of the blade heads are in contact with the branches. When the distance between the two matching blade heads is reduced, the blade heads will move away from the branches relative to the branches, and only a part of the branches can be cut off at a time. It is necessary to repeat the horizontal movement action multiple times to gradually cut off the branches. During the multiple horizontal movements, since the hedge shears are controlled by people, the hedge shears cannot be kept at the same level, so there will be deviations in the cutting position of each branch, which slows down the cutting speed of thick branches, thereby affecting the pruning efficiency. To solve the above problems, please refer to Figures 1 to 13 The present invention provides a technical solution: a mowing device for greening construction, comprising a fixed blade holder 1, a plurality of first blade heads 14 are evenly installed on one side of the fixed blade holder 1, a movable blade holder 7 is provided on one side of the fixed blade holder 1 for sliding contact with the fixed blade holder 1, a plurality of second blade heads 15 matching with the first blade heads 14 are evenly installed on one side of the movable blade holder 7, a U-shaped frame 5 is connected and fixed at one end of the fixed blade holder 1, a connecting plate 2 is slidably installed in the space formed by the U-shaped frame 5 and the fixed blade holder 1, and one end of the connecting plate 2 is fixedly connected to the movable blade holder 7 The connecting plate 2 is connected to the crank 3 for rotation away from the movable tool holder 7, and the crank 3 is rotatably installed with a driving wheel 4 for installation on the motor output shaft at one end away from the connecting plate 2. A connecting seat 6 for installation on the shell surface is installed on one side of the U-shaped frame 5. When the motor is working, the driving wheel 4 is driven to rotate, and the driving wheel 4 drives the connecting plate 2 to move along the space formed by the U-shaped frame 5 and the fixed tool holder 1 through the crank 3. At this time, the movable tool holder 7 and the fixed tool holder 1 produce relative sliding, so that the first tool head 14 and the second tool head 15 are repeatedly overlapped and misaligned.

[0023] An oblong opening 26 is provided on one side of the fixed tool holder 1 away from the motor, and a strip shell 8 is provided on the side of the oblong opening 26 away from the movable tool holder 7. Both ends of the strip shell 8 are connected and fixed with connecting edges 31. A convex edge 10 is provided between the strip shell 8 and the fixed tool holder 1, and the convex edge 10 is connected and fixed to the fixed tool holder 1. A connecting edge 31 of the strip shell 8 close to the convex edge 10 is connected to the convex edge 10 by multiple screws, and a connecting edge 31 of the strip shell 8 away from the convex edge 10 is connected to the shell cover 9 by multiple screws. The convex edge 10 is installed on the fixed tool holder 1, and the convex edge 10 and the connecting edge 31 are connected by multiple sets of screws to complete the assembly of the strip shell 8 and the fixed tool holder 1, thereby increasing the thickness of the fixed tool holder 1 where the strip shell 8 is installed.

[0024] A removable shell cover 9 is installed on the side of the strip shell 8 facing away from the fixed tool holder 1, and two driving sprockets 13 are provided on the side of the shell cover 9 facing away from the strip shell 8. A strip opening is opened in the area where the movable tool holder 7 overlaps with the oblong opening 26, and a positioning plate 18 is installed in the strip opening. One end of the positioning plate 18 extends into the strip shell 8, and a side of the positioning plate 18 is equidistantly opened with a plurality of rectangular grooves 27 on the side away from the movable tool holder 7. A plurality of rectangular grooves 27 are rotatably installed with shifting teeth 28. When the shifting teeth 28 are in a vertical state with the positioning plate 18, the shifting teeth 28 fit with the inner wall of the rectangular groove 27 away from the motor. A transmission shaft 35 is connected and fixed to the middle position of one side of the two driving sprockets 13. The transmission shaft 35 passes through the shell cover 9 and is rotatably connected to the shell cover 9. A driven gear 30 is installed on one end of the two transmission shafts 35 in the strip shell 8, and two mutually meshing middle gears 30 are provided between the two driven gears 30. The intermediate gear 32 and the two intermediate gears 32 are respectively meshed with the two driven gears 30. The intermediate gear 32 is rotatably connected to the support plate 33 through a connecting shaft. The support plate 33 is connected to the shell cover 9 through a connecting screw 37. A driving gear 29 meshing with the shifting tooth 28 is provided on the lower side of a driven gear 30. The driving gear 29 is fixedly connected to a transmission shaft 35. When the shifting tooth 28 moves in a direction away from the U-shaped frame 5, an inner wall of the rectangular groove 27 limits the rotation of the shifting tooth 28, so that the relative positions of the plurality of shifting teeth 28 and the positioning plate 18 remain unchanged. At this time, the shifting tooth 28 is meshed with the driving gear 29 and drives the driving gear 29 to rotate. Under the transmission of the two driven gears 30 and the two intermediate gears 32, the two driving sprockets 13 are rotated toward each other. When the shifting tooth 28 moves in a direction close to the U-shaped frame 5, the shifting tooth 28 rotates, thereby not providing driving force to the driving gear 29.

[0025] Two first arm plates 20 are symmetrically mounted on one side of the shell cover 9 away from the strip shell 8. The ends of the two first arm plates 20 away from the shell cover 9 are both rotatably mounted with a synchronization shaft 22. A driven sprocket 11 matching the driving sprocket 13 is mounted on one end of the synchronization shaft 22. The driving sprocket 13 and the corresponding driven sprocket 11 are meshed with a first chain 12. The ends of the two synchronization shafts 22 away from the driven sprocket 11 are both rotatably mounted with a second arm plate 17. The ends of the second arm plate 17 away from the synchronization shaft 22 are It is connected and fixed to the fixed tool holder 1, so that one end of the second arm plate 17 is connected and fixed to the flange 10, thereby improving the stability of the connection between the second arm plate 17 and the fixed tool holder 1. Under the transmission of the first chain 12, the driven sprocket 11 and the two synchronous sprockets 23 rotate. At this time, the second chain 16 rotates around the synchronous sprocket 23 and the reversing sprocket 25. At this time, multiple groups of pins 41 move with the corresponding second chain 16 to provide power for the movement of the pins 41, without the need to add an additional power source to drive the pins 41 to move.

[0026] Both ends of the support plate 33 are connected and fixed with L-shaped plates 34. A pad 36 connected and fixed to the shell cover 9 is provided between the L-shaped plate 34 and the shell cover 9. The connecting screw 37 passes through the L-shaped plate 34 and is threadedly connected to the pad 36. Two axial holes matching the transmission shaft 35 are provided on the support plate 33. The transmission shaft 35 passes through the axial holes and the transmission shaft 35 is rotatably connected to the support plate 33. When the support plate 33 and the shell cover 9 are connected by screws, the two L-shaped plates 34 on the support plate 33 are aligned with the pad 36 respectively, and then the connecting screw 37 passes through the L-shaped plate 34 and is threadedly connected to the pad 36 to complete the assembly of the support plate 33 and the shell cover 9, thereby partially increasing the thickness of the shell cover 9 where the support plate 33 is installed. The support plate 33 and the shell cover 9 jointly realize two-point support for the transmission shaft 35, thereby improving the stability of the structure.

[0027] One end of the two synchronous shafts 22 close to the second support arm plate 17 is sleeved with a synchronous sprocket 23 connected and fixed to the synchronous shaft 22, and one end of the two second support arm plates 17 close to the fixed tool holder 1 is rotatably installed with a reversing sprocket 25 that matches the synchronous sprocket 23. A second chain 16 is meshed between the synchronous sprocket 23 and the corresponding reversing sprocket 25. A support ear 39 is connected and fixed to each link of the second chain 16. A circular hole 46 is opened on one side of the support ear 39. A column 40 rotatably connected to the support ear 39 is inserted in the circular hole 46, wherein slip rings 44 are provided on both sides of the circular hole 46 along the length direction of the column 40. The slip ring 44 is in sliding contact with the support ear 39. The slip ring 44 is sleeved on the column 40 and connected and fixed to the column 40. Under the restriction of the two slip rings 44, the relative position of the column 40 and the support ear 39 remains unchanged.

[0028] A rectangular cavity 21 penetrating the column 40 is provided on one side of the column 40, a spring 47 is inserted in the rectangular cavity 21, a plugging cover 45 is installed on one side of the rectangular cavity 21 close to the inner side of the second chain 16, an end cap 43 is installed on the end of the column 40 away from the plugging cover 45, a through hole is provided on one side of the end cap 43, a pin 41 is inserted in the through hole, one end of the pin 41 is connected and fixed with a sliding block 48, the sliding block 48 is slidably installed in the rectangular cavity 21, the spring 47 is arranged between the sliding block 48 and the plugging cover 45, so that the end of the pin 41 equipped with the sliding block 48 is installed in the rectangular cavity 21 of the column 40, and the spring 47 is installed between the sliding block 48 and the plugging cover 45, when the pin 41 is subjected to the reaction force of the branch rod, the pin 41 drives the sliding block 48 to squeeze the spring 47, so that the spring 47 generates an elastic shape The change achieves the effect of buffer protection, so that the thicker branch rod is between the two second chains 16, and the pins 41 on the two second chains 16 penetrate into the branch rod counted between the two second chains 16. Under the restriction of the pins 41 and the second chain 16, the branch rod moves toward the first blade head 14 and the second blade head 15, so that when the distance between the first blade head 14 and the second blade head 15 is reduced, the first blade head 14 and the second blade head 15 will not move away from the branch rod relative to the branch rod, and there is no need to repeat the lateral movement action for many times to gradually cut the branch rod, so that the speed of cutting the thick branch rod is faster, and the pruning efficiency of the thicker branch rod is improved. When the spring 47 is in the squeezed state, the second chain 16 will be in a taut state under the reaction force of the branch rod, reducing the probability of the second chain 16 falling off.

[0029] Embodiment 2: After the thicker branch rod is clamped by the insertion pin 41, it moves toward the first blade head 14 and the second blade head 15. Since the first blade head 14 and the second blade head 15 between the two second chains 16 remain unchanged, the first blade head 14 and the second blade head 15 between the two second chains 16 are subjected to a greater load when cutting the thicker branch rod. Compared with the first blade head 14 and the second blade head 15 at other positions, the first blade head 14 and the second blade head 15 between the two second chains 16 are subjected to greater wear, which affects the service life of the first blade head 14 and the second blade head 15 between the two second chains 16. To solve the above problems, please refer to Figure 1-Figure 13The end of the column 40 close to the plug cover 45 is sleeved with a moving gear 38 connected and fixed to the column 40, and the end of the pin 41 away from the sliding block 48 is connected and fixed with a secondary needle head 42, and the secondary needle head 42 is an L-shaped structure. The two second arm plates 17 are both equipped with a rack 24 meshing with the moving gear 38, and a weight reduction port 19 is opened on one side of the rack 24. The secondary needle head 42 of the L-shaped structure is installed at one end of the pin 41, and the column 40 is rotatably connected to the ear 39. Because the rectangular sliding block 48 is slidably installed in the rectangular cavity 21, the structure formed by the pin 41 and the secondary needle head 42 also rotates when the column 40 rotates. After the moving gear 38 on 40 is meshed with the rack 24, driven by the second chain 16, the moving gear 38 moves along the length direction of the rack 24 and rotates, so that the structure formed by the insertion pin 41 and the auxiliary needle head 42 rotates, and then the rotating auxiliary needle head 42 realizes the drilling operation on the branch, realizes the early damage of the thicker branch, and makes the thickness of the branch moved to the first cutter head 14 and the second cutter head 15 smaller, so as to share the workload of the first cutter head 14 and the second cutter head 15, which is beneficial to reduce the wear of the first cutter head 14 and the cutter head, and extend the service life of the first cutter head 14 and the second cutter head 15.

[0030] The structure formed by the shell cover 9 and the strip shell 8 serves to hide the driving gear 29, the intermediate gear 32 and the driven gear 30, and at the same time provides a supporting carrier for the driving sprocket 13, etc. When the branch rod moves to the strip shell 8 driven by the second chain 16, the branch rod will be separated from the insertion pin 41 and the auxiliary needle head 42 under the joint action of the blocking of the strip shell 8 and the continued rotation of the second chain 16, thereby removing the branch rod from the insertion pin 41 and the auxiliary needle head 42.

[0031] A mowing method for greening construction comprises the following steps: Step 1: First, the first blade head 14 and the second blade head 15 on the fixed blade holder 1 and the movable blade holder 7 cooperate with each other to cut and remove the branches around the thicker branches, and retain the thicker branches; Step 2: Then place the thicker branch rod between the two second chains 16; Step 3: Move the structure formed by the fixed tool holder 1 and the movable tool holder 7 toward the thicker branch rod, so that the pins 41 on the two second chains 16 penetrate into the thicker branch rod, and as the second chain 16 rotates, the thicker branch rod moves toward the first blade head 14 and the second blade head 15.

[0032] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
