DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0026] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0027] See also Figures 1 to 5 The utility model embodiment provides a municipal garden mowing and collecting device, which includes: an electric trolley 1, a harvesting component 2 is provided on the steering handle of the electric trolley 1, and a collection box 3 for collecting grass leaves is provided on the electric trolley 1.
[0028] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The harvesting assembly 2 includes a supporting shell 21, a fixed blade 211 is provided on one side of the supporting shell 21, a movable blade 212 is provided above the fixed blade 211 in the supporting shell 21, an inner shell 22 is provided on the other side of the supporting shell 21, a crushing barrel 222 is provided inside the inner shell 22, both ends of the crushing barrel 222 are rotatably connected to the inside of the supporting shell 21, fixed teeth 221 are provided inside the inner shell 22 that are staggered with the crushing teeth in the crushing barrel 222, a motor 223 is provided at one end of the crushing barrel 222, and a movable blade 212 is provided on the other end of the crushing barrel 222. There is a linkage rod 24, and a plurality of evenly distributed extrusion rods 241 are provided on the outer wall of the linkage rod 24. A telescopic rod 232 is provided on the side wall of the outer wall of the support shell 21 opposite to the linkage rod 24. An adapter plate 23 is provided at the end of the telescopic rod 232. The outer wall of the adapter plate 23 is fixedly connected to the end of the movable blade 212. A first spring 231 is arranged between the adapter plate 23 and the support frame 215. A protrusion 233 is provided on the outer wall of the adapter plate 23. The outer wall of the protrusion 233 is a slope structure, and the outer wall of the protrusion 233 is against and slidably connected to the outer wall of the extrusion rod 241.
[0029] It should be noted that: when the motor 223 drives the crushing barrel 222 to rotate, the crushing barrel 222 can drive the linkage rod 24 and its squeezing rod 241 at the end to rotate synchronously. When the rotating squeezing rod 241 abuts against the protrusion 233 on the adapter plate 23, since the outer wall of the protrusion 233 is a slope structure, the slope structure can convert the squeezing force of the squeezing rod 241 into a driving force for squeezing the adapter plate 23. At this time, the adapter plate 23 can squeeze the movable blade 212 to drive the movable blade 212 to move.
[0030] When the squeezing rod 241 moves out from the outer wall of the protrusion 233, the first spring 231 can squeeze the adapter plate 23 through its own force, so that the adapter plate 23 is reset, thereby driving the movable blade 212 to move in the opposite direction, so that the movable blade 212 can move back and forth. When the movable blade 212 moves back and forth, the lawn between the fixed blade 211 and the movable blade 212 can be harvested. At this time, the rotating crushing barrel 222 can scrape up the harvested grass leaves, and the light-proof meshing with the fixed teeth 221 can complete the secondary crushing of the grass leaves, making the grass leaves smaller, so that the later suction and collection of the grass leaves can be more convenient.
[0031] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 A cylinder 213 and a guide rod 214 are provided on the support shell 21, a support frame 215 is provided at the top of the cylinder 213, the inner wall of the support frame 215 is slidably connected to the outer wall of the guide rod 214, and the support frame 215 is connected to the steering handle of the electric car 1 by bolts.
[0032] It should be noted that: through the installation of the cylinder 213, during use, the staff can adjust the height of the fixed blade 211 and the movable blade by controlling the operation of the cylinder 213, thereby adjusting the lawn harvesting height. Through the setting of the guide rod 214, when the cylinder 213 is working, the guide rod 214 can move with the support shell 21. When the cylinder 213 stops working, the guide rod 214 can increase the horizontal support strength of the cylinder 213, thereby making the cylinder 213 support the support shell 21 and other components more stable.
[0033] In the embodiments of the present invention, please refer to Figure 1 and Figure 5 A fan 4 is provided on the outer wall of the collecting box 3, and a connected intake pipe 41 and an exhaust pipe 42 are respectively provided on both sides of the outer wall of the fan 4, and the exhaust pipe 42 extends into the collecting box 3. A support sheet 5 is provided on the outer wall of the intake pipe 41, and a sliding frame 51 slidably connected is inserted into the interior of the support sheet 5. A second spring 52 is arranged between the sliding frame 51 and the support sheet 5, and a universal wheel 53 is arranged at the bottom of the sliding frame 51, and a scraping frame 6 is provided on the sliding frame 51. A connecting hose 61 connected to the scraping frame 6 is provided inside the scraping frame 6, and the top end of the connecting hose 61 is connected to the end of the intake pipe 41.
[0034] It should be noted that: by adopting the second spring 52 to set up the sliding frame 51, during use, the second spring 52 can squeeze the sliding frame 51 through its own force, so that the universal wheel 53 at the bottom of the sliding frame 51 can always be against the ground, so that the scraping frame 6 outside the sliding frame 51 can always maintain a relatively uniform height with the ground, thereby reducing the obstruction of the electric vehicle 1 to the travel caused by the scraping frame 6 and the ground when encountering areas with different ground heights, and thus the scraping frame 6 can always smoothly scrape and gather the crushed grass leaves, which is convenient for the fan 4 to absorb the grass leaves through the suction pipe 41 and transport the grass leaves to the inside of the collection box 3 for storage, which is convenient for the secondary utilization of the grass leaves in the later stage;
[0035] When the sliding frame 51 is moved up and down by the connecting hose 61, the scraper frame 6 is driven to move synchronously. The connecting hose 61 between the scraper frame 6 and the suction pipe 41 can be contracted synchronously, thereby avoiding obstruction to the movement of the scraper frame 6.
[0036] In the embodiments of the present invention, please refer to Figure 1 and Figure 5 An inner box 31 is inserted into the collecting box 3 and fixedly connected by bolts, and an exhaust hole 32 is opened on the inner top of the collecting box 3.
[0037] It should be noted that: by inserting the inner box 31 inside the collecting box 3, after the grass leaves are collected later, the inner box 31 can be pulled out of the collecting box 3, and then the collected grass leaves can be taken and placed, which can make it more convenient for the staff to transfer the grass leaves later. Through the setting of the exhaust hole 32, when the fan 4 transports the grass leaves to the inside of the collecting box 3, the exhaust hole 32 can facilitate the gas to be discharged from the inside of the collecting box 3 to the outside.
[0038] The working principle of the municipal garden grass cutting and collecting device provided by the utility model is as follows:
[0039] When the device is used later, the staff can drive the electric trolley 1 to drive the device. During this process, the motor 223 and the fan 4 can be controlled to rotate;
[0040] The rotating motor 223 can drive the crushing barrel 222 in the harvesting assembly 2 to rotate, and the rotating crushing barrel 222 can drive the linkage rod 24 at the end to rotate synchronously, and the rotating linkage rod 24 can drive the squeezing rod 241 on the outer wall to rotate. When the rotating squeezing rod 241 abuts against the protrusion 233 on the adapter plate 23, since the outer wall of the protrusion 233 is a slope structure, the slope structure can convert the squeezing force of the squeezing rod 241 into a driving force for squeezing the adapter plate 23. At this time, the adapter plate 23 can squeeze the movable blade 212 to drive the movable blade 212 to move;
[0041] When the squeezing rod 241 moves out from the outer wall of the protrusion 233, the first spring 231 can squeeze the adapter plate 23 by its own force, so that the adapter plate 23 is reset, thereby driving the movable blade 212 to move in the opposite direction, and then the movable blade 212 can be moved back and forth. When the movable blade 212 is moving back and forth, the lawn between the fixed blade 211 and the movable blade 212 can be harvested.
[0042] After the lawn is harvested, the crushing cylinder 222 that rotates at the back can scrape up the harvested grass leaves. At this time, when the grass leaves rotate with the crushing cylinder 222 and move to the fixed teeth 221, the fixed teeth 221 and the crushing cylinder 222 are engaged to complete the secondary crushing of the grass leaves, making the grass leaves smaller, so that the grass leaves can be sucked and collected more conveniently in the later stage.
[0043] When the scraper frame 6 moves to the grass leaf crushing position along with the electric trolley 1 and collects the crushed grass leaves, the working fan 4 can absorb the grass leaves gathered inside the scraper frame 6 through the connected scraper frame 6, so that the grass leaves can be discharged into the collection box 3 through the exhaust pipe 42, thereby realizing the centralized collection of the grass leaves, and making it convenient for the secondary utilization of the grass leaves in the later stage.
[0044] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
[0045] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
