Technical Field
[0001] This utility model relates to the field of grass suction machine technology, specifically to a self-blowing and self-suctioning grass suction machine. Background Technology
[0002] In landscaping projects, trees are often planted around or within lawns to improve the overall harmony and aesthetics of the greenery. During lawn maintenance, some tree leaves naturally fall onto the lawn, and regular trimming by gardeners also creates plant debris. These dead and fallen leaves affect the lawn's appearance, and because they float on the lawn, cleaning them manually is very difficult and inefficient.
[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention
[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a self-blowing and self-suctioning grass vacuumer with a simple structure, integrating leaf blowing and leaf suction, and high cleaning efficiency.
[0005] The solution adopted by this utility model to solve the technical problem is: a self-blowing and self-suctioning grass vacuumer, including a grass vacuum box, a wheel mechanism at the bottom of the grass vacuum box, a partition plate inside the grass vacuum box dividing the grass vacuum box into an upper negative pressure chamber and a lower positive pressure chamber, an arc-shaped plate on one side of the partition plate for forming a Laval tube with the side wall of one side of the grass vacuum box, a fan mechanism between the other side of the partition plate and the side wall of the grass vacuum box, the air inlet of the fan mechanism facing upward to draw in air from the upper negative pressure chamber to form a negative pressure in the upper negative pressure chamber, the air outlet of the fan mechanism facing downward to blow grass clippings and drive the grass clippings through the Laval tube into the upper negative pressure chamber, and a filter screen located above the partition plate inside the grass vacuum box to prevent grass clippings from clogging the fan mechanism.
[0006] Furthermore, in order to install the blower inside the suction box and ensure that the blower blows the grass clippings downwards towards the Laval tube, so that the blown grass clippings are sucked into the upper negative pressure chamber through the Laval tube, the suction box is provided with a mounting plate for installing the blower mechanism. The mounting plate is inclined from front to back and from bottom to top inside the suction box. One side of the mounting plate is connected to the side wall of the suction box, and the other side of the mounting plate is connected to the partition plate. The blower mechanism includes several blowers, which are inclinedly arranged on the mounting plate to ensure that the blowers blow the grass clippings downwards towards the Laval tube.
[0007] Furthermore, to prevent grass clippings from being sucked into the blower and causing blockage, thus affecting the normal operation of the blower, the filter screen is made of steel wire mesh. One side of the filter screen is installed on the upper end of the arc-shaped plate, and the other three sides of the filter screen are installed on the side wall of the grass suction box.
[0008] Furthermore, in order to drive the grass suction box to move on its own and clean up leaves and grass clippings on the ground, the self-blowing and self-vacuuming grass vacuum also includes a driver for dragging the grass suction box, which is a robot dog or an electric trolley.
[0009] Furthermore, to facilitate pushing the grass vacuum box to clean leaves and grass clippings on the ground, the grass vacuum box is equipped with a push rod for pushing the grass vacuum box. The push rod has a U-shaped structure, and the two sides of the push rod are welded to the two ends of the upper rear side of the grass vacuum box.
[0010] Furthermore, to ensure the grass suction box is movable to clean leaves and grass clippings on the ground, the wheel mechanism includes two front wheels and one omnidirectional wheel. Two triangular brackets are provided on both sides of the front end of the bottom of the grass suction box, and the two front wheels are respectively mounted on the two triangular brackets. A U-shaped bracket is provided on the rear side of the bottom of the grass suction box, and the omnidirectional wheel is installed in the middle of the U-shaped bracket.
[0011] Furthermore, in order to drive the grass suction box to move on its own to clean up leaves and grass clippings on the ground, the wheel mechanism also includes an electric drive for driving the wheel mechanism to move.
[0012] Furthermore, in order to create a closed space at the bottom of the suction box to ensure that the leaves and grass clippings blown up by the fan are sucked into the upper negative pressure chamber, sealing plates are also installed around the bottom of the suction box to contact the ground and create a closed space at the bottom of the suction box.
[0013] Compared with the prior art, this utility model has the following advantages: This utility model integrates leaf blowing and leaf suction into one unit. By setting up a set of fans, leaf blowing and suction can be completed simultaneously. Specifically, the partition plate divides the suction box into an upper negative pressure chamber and a lower positive pressure chamber. The fans are inclined on the partition plate. Because the air inlet of the fan is at the top and the air outlet is at the bottom, the air in the upper negative pressure chamber is drawn into the fan, causing the air pressure in the upper negative pressure chamber to decrease. In conjunction with the fan, the air is blown towards the ground, and the blown fallen leaves drift downwards towards the Laval tube. Under negative pressure, the leaves are sucked into the Laval tube and accelerated by the Laval tube before falling into the upper negative pressure chamber. The filter screen installed in the upper negative pressure chamber traps the fallen leaves, preventing them from being sucked into the fan and causing blockage, thus ensuring the normal operation of the fan. In addition, this invention also has a sealing plate installed below the suction box. The sealing plate forms a closed space below the suction box, which can better ensure that the fallen leaves blown by the fan are sucked into the upper negative pressure chamber, thereby ensuring the cleaning effect of the fallen leaves.

The grass vacuum box 1 is also provided with a filter screen 4 located above the partition plate 2 to prevent grass clippings from clogging the fan 10 mechanism.
[0022] In this embodiment, in order to install the blower 10 inside the suction box 1 and ensure that the blower 10 blows the grass clippings downwards towards the Laval tube 103, so that the blown grass clippings are sucked into the upper negative pressure chamber 101 through the Laval tube 103; the suction box 1 is provided with a mounting plate 5 for installing the blower 10 mechanism. The mounting plate 5 is inclined from front to back and from bottom to top inside the suction box 1. One side of the mounting plate 5 is connected to the side wall of the suction box 1, and the other side of the mounting plate 5 is connected to the partition plate 2. The blower 10 mechanism includes a plurality of blowers 10, which are inclinedly arranged on the mounting plate 5 to ensure that the blower 10 blows the grass clippings downwards towards the Laval tube 103.
[0023] In this embodiment, in order to prevent grass clippings from being sucked into the blower 10 and causing blockage of the blower 10, thus affecting the normal operation of the blower 10, the filter screen 4 is made of steel wire mesh. One side of the filter screen 4 is installed on the upper end of the arc plate 3, and the other three sides of the filter screen 4 are installed on the side wall of the grass suction box 1.
[0024] In this embodiment, in order to drive the grass suction box 1 to move on its own to clean up leaves and grass clippings on the ground, the self-blowing and self-suctioning grass suction machine also includes a driver for dragging the grass suction box 1. The driver can be a robot dog, an electric trolley, or other self-propelled electric structure.
[0025] In this embodiment, in order to facilitate pushing the grass suction box 1 to clean up leaves and grass clippings on the ground, the grass suction box 1 is provided with a push rod 6 for pushing the grass suction box 1. The push rod 6 has a U-shaped structure, and the two sides of the push rod 6 are welded to the two ends of the upper rear side of the grass suction box 1.
[0026] In this embodiment, in order to ensure that the grass suction box 1 is movable to clean up leaves and grass clippings on the ground, the wheel mechanism includes two front wheels 7 and one omnidirectional wheel 8. Two triangular brackets are provided on both sides of the bottom front end of the grass suction box 1, and the two front wheels 7 are respectively installed on the two triangular brackets.

[0028] In this embodiment, in order to form a closed space at the bottom of the grass suction box 1 so as to ensure that the leaves and grass clippings blown by the fan 10 are sucked into the upper negative pressure chamber 101, a sealing plate 9 is also installed around the bottom of the grass suction box 1 to contact the ground and form a closed space at the bottom of the grass suction box 1.
[0029] This utility model integrates leaf blowing and leaf suction into one unit. By setting up a set of fans 10, leaf blowing and suction can be completed simultaneously. Specifically, the partition plate 2 divides the grass suction box 1 into an upper negative pressure chamber 101 and a lower positive pressure chamber 102. The fans 10 are inclined on the partition plate 2. Because the air inlet of the fans 10 is at the top and the air outlet is at the bottom, the air in the upper negative pressure chamber 101 is drawn into the fans 10, causing the air pressure in the upper negative pressure chamber 101 to decrease. In conjunction with the fans 10, the air is blown towards the ground, and the blown fallen leaves drift towards the bottom of the Laval tube 103 and are sucked in under the negative pressure. The leaves are accelerated through the Laval tube 103 and fall into the upper negative pressure chamber 101. The filter screen 4 installed in the upper negative pressure chamber 101 traps the fallen leaves, preventing them from being sucked into the fan 10 and causing blockage, thus ensuring the normal operation of the fan 10. In addition, this utility model also provides a sealing plate 9 below the suction box 1. The sealing plate 9 forms a closed space below the suction box 1, which can better ensure that the fallen leaves blown by the fan 10 are sucked into the upper negative pressure chamber 101, thereby ensuring the cleaning effect of the fallen leaves.
