Description

Technical Field

[0001] This invention relates to the field of landscape equipment technology, specifically an automatic weed collection device for lawn weeding. Background Technology

[0002] Landscape design is the process of creating a beautiful natural environment and a space for living and recreation within a defined area by using landscape art and engineering techniques, such as modifying the terrain, planting trees and flowers, constructing buildings, and arranging garden paths. Lawns are relatively large areas in gardens and are frequently used by people. Lawns need to be mowed periodically. In the past, this was done manually, but with the development of technology, lawnmowers have emerged that can automatically mow lawns in gardens.

[0003] However, existing lawn mowers produce grass clippings that fall directly onto the lawn during the mowing process, requiring garden maintenance personnel to collect and clean them up. However, large lawns result in a heavy workload for workers and low efficiency in cleaning up the clippings, requiring a considerable amount of time to clean them up. Therefore, there is a need for an automatic collection device for lawn mowing to collect and clean up the grass clippings generated during the mowing process. Summary of the Invention

[0004] To address the above problems, the present invention provides an automatic weed collection device for garden lawns.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: An automatic collection device for weeding lawns is characterized by comprising a housing, a picking and feeding mechanism, a sand filter tray, and a fan. The bottom of the housing is equipped with pulleys, and the front end of the housing is equipped with a hook that attaches to a hanging hole at the rear of a weed cutter. The housing contains a collection chamber with a suction channel at its front end. The picking and feeding mechanism is installed at the entrance of the suction channel and is used to pick up grass clippings from the lawn and deliver them to the entrance of the suction channel. The sand filter tray is located at the bottom of the collection chamber and is used to filter out any sand particles attached to the grass clippings within the collection chamber. The fan is installed at the rear end of the collection chamber and, during use, draws air from the collection chamber to create a negative pressure inside.

[0006] A further technical solution of the present invention is as follows: the picking and feeding mechanism includes a picking roller, a blocking structure and a drive motor. The picking roller is rotatably installed in front of the inlet of the suction channel. The picking roller is used to pick up grass clippings on the lawn and send them to the inlet of the suction channel. The drive motor is used to drive the picking roller to rotate. The blocking structure is fixedly installed at the inlet of the suction channel. The blocking structure is used to intercept the grass clippings picked up by the picking roller and sent to the inlet of the suction channel.

[0007] A further technical solution of the present invention is as follows: the picking roller includes a rotating shaft and a guide plate, the guide plate is arranged around the rotating shaft and fixed on the rotating shaft, the guide plate is arc-shaped and the outer edge of the guide plate is provided with a groove.

[0008] A further technical solution of the present invention is as follows: the baffle structure includes a baffle plate, which is fixed side by side on the upper side of the inlet of the suction channel, and the baffle plate is offset from the guide plate; when the rotating shaft drives the guide plate to rotate and pass through the inlet of the suction channel, the guide plate will pass by the side of the baffle plate.

[0009] A further technical solution of the present invention is as follows: the two ends of the rotating shaft are rotatably mounted by bearings, and the end of the rotating shaft is provided with a transmission wheel, which is connected to the transmission wheel on the output shaft of the drive motor by a transmission belt.

[0010] A further technical solution of the present invention is that the end of the guide plate away from the rotating shaft is a pointed tip.

[0011] A further technical solution of the present invention is as follows: the bottom of the collection chamber is provided with an opening, the sand filter is fixed at the opening at the bottom of the collection chamber, and the sand filter is provided with filter holes.

[0012] A further technical solution of the present invention is as follows: the sand filter tray includes a support frame and a convex plate. The support frame is fixed at the opening at the bottom of the collection chamber, the convex plate is fixed in the support frame, and the periphery of the convex plate is recessed to form a sand collection groove. The filter hole is provided on the bottom surface of the sand collection groove.

[0013] A further technical solution of the present invention is: the upper surface of the convex plate is provided with notches arranged side by side.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The automatic collection device of the present invention is separate from the weeder and is not integrated into the weeder, making it more flexible to use. When in use, the automatic collection device of the present invention is connected to the weeder by hooks, moves with the weeder, and collects the grass clippings cut by the weeder.

[0015] The automatic collection device of this invention uses a pick-up and feeding mechanism to pick up grass clippings from the lawn and deliver them to the inlet of the suction channel. A fan creates negative pressure in the collection chamber, drawing the grass clippings from the inlet of the suction channel into the collection chamber, thus achieving the collection of grass clippings from the lawn. Furthermore, this invention uses a sand filter to filter out any loose sand attached to the collected grass clippings, making the collected grass clippings more suitable as animal feed.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-5 The automatic collection device for weeding garden lawns in this embodiment includes a housing 2, a picking and feeding mechanism 22, a sand filter tray 25, and a fan 26.

[0020] The bottom of the housing 2 is equipped with a pulley 5, and the front end of the housing 2 is equipped with a hook 21. In use, the hook 21 will be engaged with the hanging hole at the rear of the weeder 1, so that the weeder 1 can move together with the automatic collection device. The weeder 1 illustrated in this embodiment is a conventional remote-controlled weeder.

[0021] In this embodiment, a control panel 3 is located on the upper part of the housing 2 near the front end. Inside the housing 2 is a collection chamber 24, and a top cover 4 is located on top of the collection chamber 2. Opening the top cover 4 allows the collected grass clippings in the collection chamber 24 to be removed.

[0022] See Figure 2The collection chamber 24 has a suction channel 23 at its front end, with the front end of the suction channel 23 serving as the inlet. The front end of the suction channel 23 slopes downwards and is located at the bottom of the housing 2. A pick-up and feed mechanism 22 is installed at the inlet of the suction channel 23. A sand filter disc 25 is located at the bottom of the collection chamber 24 to filter out the sand attached to the grass clippings inside the collection chamber 24 and discharge it directly to the lawn below. A blower 26 is installed at the rear end of the collection chamber 24. The blower 26 is used to discharge the air inside the collection chamber 24 outwards, creating a negative pressure inside the collection chamber 24, thereby drawing the grass clippings fed into the suction channel 23 by the pick-up and feed mechanism 22 into the collection chamber 24. Of course, a filter screen is installed at the inlet of the blower 26 to prevent a large amount of grass clippings from entering the blower 26.

[0023] See Figure 3 The picking and feeding mechanism 22 includes a picking roller 221, a baffle structure 222, and a drive motor 223. The picking roller 221 is rotatably mounted in front of the inlet of the suction channel 23. The picking roller 221 is used to pick up grass clippings from the lawn and deliver them to the inlet of the suction channel 23. The drive motor 223 is installed inside the housing 2 and is used to drive the picking roller 221 to rotate. The baffle structure 222 is fixedly mounted at the inlet of the suction channel 23. The baffle structure 222 is used to intercept the grass clippings picked up by the picking roller 221 and delivered to the inlet of the suction channel 23, so that the grass clippings fall at the inlet of the suction channel 23 and are sucked into the collection chamber 24 by the suction generated by the fan 26.

[0024] See Figure 4 The material pickup roller 221 includes a bearing 2211, a rotating shaft 2212, guide plates 2213, and a transmission wheel 2214. The two ends of the rotating shaft 2212 are rotatably mounted via the bearings 2211. Multiple guide plates 2213 are provided; in this embodiment, guide plates 2213 are arranged on multiple circumferences of the rotating shaft 2212, and the guide plates 2213 on adjacent circumferences can be staggered. The portion of the guide plates 2213 located below the rotating shaft 2212 will be located below the housing 2. The transmission wheel 2214 is located at the end of the rotating shaft 2212, and the transmission wheel 2214 is connected to the transmission wheel on the output shaft of the drive motor 223 via a transmission belt.

[0025] See Figure 5 The guide plate 2213 is arc-shaped, and the end of the guide plate 2213 away from the rotating shaft 2212 is a pointed end. The outer edge of the guide plate 2213 is provided with a groove 2215. In this embodiment, the guide plate 2213 has four grooves 2215.

[0026] The baffle structure 222 includes multiple baffles 2221, which are fixed side by side on the upper side of the inlet of the suction channel 23. The baffles 2221 are inclined downward and are offset from the guide plate 2213. When the rotating shaft 2212 drives the guide plate 2213 to rotate and pass through the inlet of the suction channel 23, the guide plate 2213 will pass through the side of the baffle 2221. There is only a small gap between the guide plate 2213 and the baffle 2221.

[0027] During use, when the rotating shaft 2212 drives the guide plate 2213 to rotate and pass through the grass under the shell 2, the cutting groove 2215 hooks up the grass clippings on the grass and lifts them together with the guide plate 2213 to the entrance of the suction channel 23. Then, the baffle plate 2221 blocks the grass clippings from the guide plate 2213 and they fall into the entrance of the suction channel 23.

[0028] Please see Figures 6-7 The sand filter tray 25 includes a support frame 251 and a convex plate 252. The bottom of the collection chamber 24 is provided with an opening. The support frame 251 is fixed to the opening at the bottom of the collection chamber 24. The convex plate 252 is fixed in the support frame 251. The upper surface of the convex plate 252 is provided with multiple parallel notches 253. The periphery of the convex plate 252 is recessed to form a sand collection groove 254. There is an inclined surface with a 30-degree inclination between the sand collection groove 254 and the convex plate 252. The bottom surface of the sand collection groove 254 is a filter sheet 255. The filter sheet 255 is provided with a plurality of filter holes 256. In this embodiment, the filter holes 256 are C-shaped. During use, the grass clippings collected in the collection chamber 24 will be located on top of the filter tray 25. As the weeder 1 moves across the lawn with the automatic collection device, the automatic collection device and the filter tray 25 will shake as a whole. The loose sand on the grass clippings on the filter tray 25 will continuously fall onto the filter tray 25. With the shaking, the loose sand will move into the sand collection trough 254 and fall out through the filter holes 256, returning to the lawn. The notch 253 increases the friction between the convex plate 252 and the grass clippings, which can better promote the turning of the grass clippings during the shaking process.

[0029] The usage process of the automatic collection device in this embodiment is as follows: In use, first attach hook 21 to the hanging hole at the rear of the weeder 1, connecting the automatic collection device to the weeder 1. Then start the weeder 1 and the automatic collection device. The weeder 1 moves and weeds according to the remote control route or a pre-planned route, carrying the automatic collection device with it during the movement. The drive motor 223 of the automatic collection device will drive the pickup roller 221 to rotate. Figure 2(The arrow in the image indicates the rotation direction of the picking roller 221). When the guide plate 2213 of the picking roller 221 moves to the bottom, it hooks up grass clippings on the lawn through the cutting groove 2215. The grass clippings are lifted along with the guide plate 2213 to the entrance of the suction channel 23. When the grass clippings reach the entrance of the suction channel 23, they are intercepted by the baffle plate 2221 and fall into the entrance of the suction channel 23. Then, under the suction force generated by the fan 26, they are sucked into the collection chamber 24, thus collecting the grass clippings. The collected grass clippings will be located on top of the filter tray 25. As the weeder 1 moves across the lawn with the automatic collection device, the automatic collection device and the filter tray 25 will shake as a whole. The loose sand on the grass clippings on the filter tray 25 will continuously fall onto the filter tray 25 and eventually fall through the filter holes 256 back onto the lawn.

[0030] After weeding is completed, the top cover 4 can be opened to remove the grass clippings collected in the collection chamber 24. Since the sand in the grass clippings has been filtered out, the collected grass clippings can be used as animal feed.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
