Description

Technical Field

[0001] The utility model belongs to the technical field of lawn mowing, in particular to a hedge trimming mechanical trolley. Background Art

[0002] In the process of landscaping maintenance, lawns and hedges often need to be trimmed. Unlike lawns, hedges have a certain height, so trimming is more troublesome.

[0057] Example 1

[0058] like Figure 1-9 As shown, a hedge trimming mechanical trolley includes a frame 1 (the dimensions of the frame 1 are: width 230 mm, length 252 mm, height 136 mm, capable of free movement in the workplace, and the material is preferably lightweight aluminum alloy), and a hedge trimming mechanism is installed on the top of the frame 1.

[0059] Specifically, the hedge trimming mechanism includes a robotic arm 5 (a conventional robotic arm 5 known in the prior art) and a pruning blade assembly 4 mounted on the robotic arm 5. During operation, the robotic arm 5 drives the pruning blade assembly 4 to trim the hedge. Because the robotic arm 5 can be adjusted at multiple angles and orientations, the hedge can be trimmed flexibly.

[0060] At the same time, a plurality of running mechanisms 2 are installed at the bottom edge of the frame 1. Specifically, a pair of running mechanisms 2 are installed at the end and the tail of the frame 1 and are respectively arranged on both sides of the frame 1.

[0061] Specifically, the running mechanism 2 adjusts the height between the bottom of the frame 1 and the ground through the height adjustment structure. During operation, the running wheels use the ground as a support pad to lift the frame 1 upward to avoid and cross obstacles.

[0062] At the same time, a bottom rotary blade mechanism 6 is installed at the bottom of the vehicle frame 1. When the vehicle frame 1 is moving, the bottom rotary blade mechanism 6 is used to trim the lawn. The bottom rotary blade mechanism 6 trims the lawn and cooperates with the hedge trimming mechanism to trim the lawn and the hedge to a certain height. During the greening maintenance process, the lawn and hedge can be trimmed at the same time, which greatly increases work efficiency and effectively reduces trimming and maintenance costs.

[0063] At the same time, a storage mechanism 3 is installed at the rear of the frame 1, which can store debris generated by the hedge trimming mechanism and the bottom rotary blade mechanism. The storage mechanism 3 can store broken branches and leaves generated during the trimming process, completing the trimming and debris removal in one go, further improving the efficiency of trimming and maintenance.

[0064] Example 2

[0065] like Figure 1-9 As shown, this embodiment is based on the structure of Example 1. The travel mechanism 2 includes a travel roller 21; the travel roller 21 is rotatably connected to a wheel frame 22 (the wheel frame 22 is a U-shaped structure), and a travel motor 25 is mounted on the wheel frame 22 to drive the travel roller 21 to rotate. The power output end of the travel motor 25 is mounted on the roller.

[0066] The height adjustment structure includes an electric push rod 23 mounted on the wheel frame 22. The electric push rod 23 is tilted and fixed to the top of the wheel frame 22 via a mounting seat structure 231 (the mounting seat structure 231 specifically comprises: the end of the push rod is fixedly connected to the mounting tongue, the top of the wheel frame 22 is fixedly connected to the mounting seat, and the mounting tongue is fastened to the mounting seat by bolts). At the same time, the upper end of the electric push rod 23 is fixedly mounted on the vehicle frame 1.

[0067] At the same time, the height adjustment structure also includes connecting arms 24 respectively installed on both sides of the wheel frame 22 (similarly, the connecting arms 24 are set at an angle); specifically, a pair of connecting arms 24 set up and down are respectively installed on both sides of the wheel frame 22.

[0068] The lower end of each connecting arm 24 is fastened to the wheel frame 22 by bolts, and the other end of each connecting arm 24 is provided with an adjustment slide A (the adjustment slide A is in the shape of a long strip to meet the adjustment of the spacing during the height adjustment process); the adjustment slide A is internally limited and slidingly connected with a fastening screw, which is fixedly mounted on the frame 1.

[0069] During the working process, when the frame 1 needs to be raised to avoid obstacles or cross obstacles, the electric push rod 23 works. Specifically, the electric push rod 23 pushes the wheel frame 22-travel roller 21 downward, and the travel roller 21 uses the ground as a fulcrum, thereby raising the frame 1. After the frame 1 is raised, the distance between the frame 1 and the ground increases, thereby achieving avoidance or crossing obstacles.

[0070] During this process, the tightening screw slides in the adjustment slot A of the connecting arm 24 .

[0071] Example 3

[0072] like Figure 1-9As shown, this embodiment is based on the structure of embodiment 2. In order to trim hedges, the pruning blade assembly 4 includes a pair of brackets 41 fixedly mounted on the robotic arm 5 (the center portion of the bracket 41 is fixedly connected to a fixing seat 411 that fixes the brackets 41 on both sides).

[0073] At the same time, crank structures 44 are hinged on the brackets 41, and the crank structures 44 are respectively installed with pruning knife brackets 42; the inner ends of the pruning knife brackets 42 are hinged on the brackets 41 (the inner ends of the pruning knife brackets 42 are hinged on the brackets 41 through hinge shafts); the outer ends of the pruning knife brackets 42 are installed with pruning knives 43.

[0074] A crank structure 444 for driving the crank structure to swing is fixedly installed in the bracket 41. The crank structure 444 is a conventional crank disclosed in the prior art.

[0075] Specifically, the robot structure 444 includes a shell fixedly installed between the brackets 41 (the core components of the robot in the robot structure 444, including the motor and other mechanisms, are installed in the shell); the shell is fixedly installed on the robotic arm 5.

[0076] At the same time, the 44 crank structure includes a first crank arm 441, which is hinged to a second crank arm 442; the second crank arm 442 is installed with the pruning knife bracket 42; the first crank arm 441 is fixedly connected to a rotating shaft 443, and according to the existing method, the rotating shaft 443 on the first crank arm 441 is installed on the power output end of the ostrich structure 444.

[0077] At the same time, the trimming knife 43 includes a knife body (total length is 125mm, width is 15mm) and a trimming tooth structure 431 installed on the knife body; the trimming tooth structure 431 is composed of multiple tooth-shaped structures (the shape of the tooth-shaped structure is a pointed cone), and the trimming tooth structure 431 is distributed on both side walls of the knife body, and the tooth pitch is 10mm.

[0078] The shape of the above-mentioned pruning knife 43 adopts a bionic design to increase the efficiency of pruning hedges (specifically, it is a bionic long strip of blades of orchids and other trees. This type of blade has a stronger shearing force than blades of other structural shapes such as elliptical blades. Therefore, the shape of the blade body adopts a bionic long strip structure).

[0079] During the working process, under the drive of the ostrich machine, the pruning knife bracket 42 and the pruning knife fit together to complete the pruning work. During the movement and fitting process of the pruning knife bracket 42 and the pruning knife, the first crank arm 441 on the crank structure drives the second crank arm 442 to rotate, and the second crank arm 442 drives the scissor bracket 41 to rotate to complete the pruning work.

[0080] Furthermore, since the pruning blade assembly 4 is mounted on the robotic arm 5, the posture of the pruning blade assembly 4 is adjusted during the pruning process by the robotic arm 5. In this way, bionic scissors pruning is achieved during the pruning process, and efficient and flexible pruning of the hedge is achieved.

[0081] Example 4

[0082] like Figure 1-9 As shown, this embodiment is based on the structure of the third embodiment. In order to complete the mowing of the lawn, the bottom rotary blade mechanism 6 includes a pair of cross-arranged rotary blades 61; the rotary blades 61 are arranged in a cross shape.

[0083] The bottom rotary cutter mechanism 6 also includes a rotary motor 62 for driving the rotary cutter to rotate; an electric telescopic rod 63 (the electric telescopic rod 63 is a conventional electric push rod disclosed in the prior art) is fixedly mounted on the top of the rotary motor 62. The electric telescopic rod 63 is fixedly mounted on the bottom of the vehicle frame 1.

[0084] During operation, when the lawn needs to be mowed, the electric telescopic rod 63 pushes the rotary motor 62 downward, and the rotary motor 62 drives the high-speed rotating blade 61 to mow the lawn. In addition, the high-speed rotating blade 61 can also be used to remove obstacles such as mud and gravel when the bottom of the frame 1 touches the ground during operation, ensuring that the vehicle can drive normally.

[0085] Specifically, the rotary motor 62 is installed with a motor bracket, and the rotary cutter 61 is rotatably connected to the motor bracket; the rotary cutter 61 is installed on the power output shaft of the rotary motor 62 in an existing manner.

[0086] At the same time, a plurality of protruding teeth 611 are integrally formed on the rotary cutter 61. The protruding teeth 611 are in the shape of a crescent.

[0087] In order to protect the rotary blade 61, a protective sleeve 64 is installed at the bottom of the frame 1, and the bottom rotary blade mechanism 6 is located in the protective sleeve 64. During lawn mowing, the rotary blade is driven to extend out of the protective sleeve 64 in the above manner.

[0088] Example 5

[0089] like Figure 1-9As shown, this embodiment is based on the structure of Example 4. In order to store the trimmed debris during the working process and complete the cleaning while trimming, the above-mentioned storage mechanism 3 includes a tail frame 31 fixedly mounted on both sides of the rear end of the frame 1, and a brush roller is rotatably connected between the tail frames 31, and a brush cover 32 is installed on the brush roller; the storage mechanism 3 also includes a drive motor for driving the brush roller (the drive motor is fixedly mounted on the tail frame 31, and its output shaft is fixedly mounted on the brush roller); the storage mechanism 3 also includes a storage box 33 corresponding to the brush roller; the storage box 33 is fixedly mounted on the tail frame 31; specifically, the feed port of the storage box 33 faces the brush roller. A box cover is installed on the top of the storage box 33, and the box cover can be opened to clean the debris in the storage box 33.

[0090] During operation, the rotating brush roller sweeps the debris toward the feed port of the storage box 33 and into the storage box 33 to complete the cleaning.

[0091] Example 6

[0092] like Figure 1-9 As shown, based on the structure of Example 1, this embodiment is similar to existing smart cars in that a camera 12 and a laser radar are installed at the end of the frame 1 to identify and plan the driving path during operation (specifically, the camera 12 and the laser radar are similar to those of existing smart cars and are connected to the control system on the car to feed back the recognized image and other signals to the control system, which controls the driving of the car). At the same time, similar to existing cars, a solar panel is installed on the top of the frame 1; the solar panel is used to power the car.

[0093] In the actual working process, similar to the existing anti-collision design of the trolley, sonic rangefinders are installed around the frame 1 to achieve anti-collision of the trolley.
