[0002] A garden is a natural environment and recreational space created within a specific area using engineering techniques and artistic methods. This involves modifying the terrain (such as building hills, stacking rocks, and managing water), planting trees and flowers, constructing buildings, and arranging garden paths. Weeding is a crucial aspect of garden maintenance; regular weeding is necessary to ensure the plants grow optimally. Weeding devices are tools or equipment used to remove weeds, and different types are suitable for different garden settings, sizes, and weed growth conditions.
[0003] Most existing weeding devices simply cut the exposed parts of weeds with high-speed rotating blades. However, some weeds retain their roots in the soil after being cut, allowing them to regenerate and grow back. Therefore, those skilled in the art have provided a novel garden weeding device to address the problems mentioned in the background section. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel garden weeding device. This device is equipped with a spraying structure that can spray herbicide on the ground after weeding to inhibit the regrowth of weeds, and can also collect the weeds after weeding, making it convenient to use.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 - Figure 3 One embodiment provided by this utility model:
[0027] A novel garden weeding device includes a housing 1 and a spraying structure 6. A collection frame 16 is fixedly installed on the front of the top surface inside the housing 1. A motor 11 is fixedly installed on the front of the bottom surface inside the housing 1. A rotating shaft 12 is fixedly installed at the output end of the motor 11. Multiple blades 13 are fixedly installed around the lower part of the rotating shaft 12. A connecting pipe 9 is fixedly installed in the middle of the lower end of the housing 1. A fan 3 is fixedly installed on the front of the upper end of the housing 1. Rollers 7 are rotatably installed on the lower part of both sides of the housing 1. A connecting rod 14 is fixedly installed between the two rollers 7 at the rear. A first bevel gear 15 is fixedly sleeved around the connecting rod 14.
[0028] A push rod 2 is fixedly installed at the upper rear end of the casing 1. The spraying structure 6 is fixedly installed inside the casing 1 at the rear end. A discharge frame 4 is fixedly installed at the middle front end of the casing 1. A frame door 5 is hinged at the front end of the discharge frame 4. A box door 8 is hinged at the rear end of the casing 1. The upper end of the connecting pipe 9 extends into the inside of the collection frame 16. The air inlet of the fan 3 extends into the top surface inside the casing 1 and a cover net 10 is fixedly installed at the air inlet.
[0029] Specifically, when motor 11 starts, its output drives shaft 12 to rotate at high speed. Since multiple blades 13 are fixedly installed at the lower part of shaft 12, these blades rotate at high speed, preparing to cut weeds. Simultaneously, fan 3 starts operating, generating suction within housing 1. The operator holds push rod 2 at the upper rear of housing 1, pushing the device forward. At this time, rollers 7 on both sides of housing 1 begin to rotate, and the connecting rod 14 between the two rear rollers 7 also rotates. As the device moves forward, the high-speed rotating blades 13 cut the weeds on the ground, severing them at the roots. The suction generated by fan 3 acts on the ground through connecting pipe 9. Under the action of suction, the cut weeds enter the collection frame 16 fixedly installed at the front of the top surface inside housing 1, achieving unified collection of weeds. The cover 10 at the air inlet of fan 3 prevents larger debris from entering fan 3, providing protection.
[0030] Reference Figure 4 - Figure 6 The spraying structure 6 includes a storage cylinder 601, a rotating cylinder 602 rotatably mounted at the lower end of the storage cylinder 601, an outer cylinder 604 movably mounted around the rotating cylinder 602, a discharge port 603 is opened at the lower front side of the rotating cylinder 602, a discharge port 605 is opened at the lower rear end of the outer cylinder 604, a discharge frame 606 is fixedly mounted at the rear end of the discharge port 605, a plurality of partitions 607 are fixedly mounted between the upper and lower inner walls of the discharge frame 606, a rotating rod 608 is fixedly mounted at the lower end of the rotating cylinder 602, a second bevel gear 609 is fixedly mounted at the lower end of the rotating rod 608, and the first bevel gear 15 and the second bevel gear 609 are meshed together.
[0031] A groove 610 is provided on the inner top surface of the discharge port 605. A baffle 611 is slidably arranged inside the groove 610. A sliding groove 615 is provided on the inner rear wall of the groove 610. A slider 613 is fixedly arranged at the upper rear end of the baffle 611. The slider 613 and the sliding groove 615 are slidably arranged. A fixing block 612 is fixedly arranged at the upper rear end of the outer cylinder 604. A screw 614 is rotatably arranged at the upper end of the slider 613. The screw 614 and the fixing block 612 are threaded together. The discharge frame 606 is fixedly connected to the housing 1 and the rear end of the discharge frame 606 passes through the rear side of the housing 1. The rotating rod 608 and the outer cylinder 604 are rotatably arranged with the housing 1.
[0032] Specifically, during the forward movement of the propulsion device, the roller 7 drives the connecting rod 14 to rotate. Since a first bevel gear 15 is fixedly fitted around the connecting rod 14, and this first bevel gear 15 meshes with a second bevel gear 609 at the lower end of the rotating rod 608 in the spraying structure 6, the rotation of the connecting rod 14 drives the rotating rod 608 to rotate, thereby causing the rotating drum 602, which is fixedly connected to the rotating rod 608, to rotate. When the rotating drum 602 rotates 180 degrees, the discharge port 603 at the lower front of the rotating drum 602 aligns with the discharge port 605 at the lower rear end of the outer drum 604. At this time, the herbicide in the storage drum 601 enters the discharge frame 606 through the discharge port 603 and the discharge port 605, and is then discharged through the discharge frame 606 onto the ground after weeding, inhibiting the regrowth of weeds. The outer drum 604 is made of silicone material, which allows for a seal between it and the rotating drum 602. Multiple partitions 607 fixedly installed between the upper and lower inner walls of the discharge frame 606 can make the herbicide discharge more evenly.
[0033] A groove 610 is formed on the inner top surface of the discharge port 605, and a baffle 611 is slidably disposed inside the groove 610. By rotating the screw 614, since the screw 614 and the fixing block 612 are threaded together, and the lower end of the screw 614 is rotatably disposed with the slider 613 at the upper rear end of the baffle 611, and the slider 613 is slidably disposed with the sliding groove 615 formed on the inner rear side of the groove 610, rotating the screw 614 can make the baffle 611 slide within the groove 610, thereby adjusting the opening size of the discharge port 605 and controlling the discharge flow of herbicide. When the baffle 611 is completely closed, the discharge of herbicide during the movement of the device can be stopped.
[0034] Working principle: When the weeding device is in use, the motor 11 and the fan 3 are started. The motor 11 drives the rotating shaft 12 to drive the blade 13 to rotate at high speed to cut the weeds. At the same time, the fan 3 generates suction, so that the cut weeds enter the collection box 16 through the connecting pipe 9 for collection.
[0035] Secondly, when the device is pushed forward during weeding, the roller 7 rotates and drives the connecting rod 14 to rotate. Since the first bevel gear 15 and the second bevel gear 609 are meshed, the rotating rod 608 rotates. The rotating rod 608 is connected to the rotating drum 602. After the rotating drum 602 rotates 180 degrees, the discharge port 603 and the discharge port 605 are aligned. The herbicide that enters the rotating drum 602 from the storage cylinder 601 is discharged through the discharge frame 606 and spread on the ground after weeding to inhibit the regrowth of weeds.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
