Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a multifunctional weeding mechanism. Background Art

[0002] In the prior art, when a lawn mower is in use, its weeding blade is a full-body blade that matches the length of the lawn mower. Therefore, the weeding blades located at different positions in the circumferential direction need to contact the ground during the movement of the lawn mower. In this case, the number of weeding blades determines the stability of the lawn mower during the movement. However, due to the limitation of the assembly space, the current weeding blades are generally provided with six weeding blades. There is an obvious bumpy feeling during the movement of the lawn mower, which is not easy to control.

[0003] At the same time, the weeding knife adopts a full-body knife structure. On the one hand, when it is partially damaged, the entire weeding knife needs to be replaced. On the other hand, due to the complex ground conditions and the long length of the weeding knife, it is easy to deform or even break during its long-term contact with the ground. Both aspects will cause the weeding knife to have relatively high costs in maintenance and use. Utility Model Content

DETAILED DESCRIPTION

[0028] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0029] according to Figures 1 to 5 As shown: This embodiment provides a multifunctional weeding mechanism, including a weeding mechanism body, which is installed at the front end of a weeder for the user to walk and weed with the weeder. The weeding mechanism body is also connected to the engine of the weeder through a conveyor belt, which is used to transmit power to the weeding mechanism body for rotation operation.

[0030] The weeding mechanism body includes a housing 900, an adjustment mechanism, a shaft 100, and a weeding assembly 400 mounted on the shaft 100; the specific implementation structure of each assembly is as follows.

[0031] The weeding components 400 include two groups, each group of weeding components 400 includes six weeding knives 300 and a first mounting plate 200 for mounting the weeding knives 300, each group of weeding components 400 is assembled by two first mounting plates 200 arranged in parallel, and the weeding components 400 are sequentially distributed along the length direction of the shaft body 100, wherein one group of weeding components 400 is located on the left side of the shaft body 100, and the other group of weeding components 400 is located on the right side of the shaft body 100, and the weeding knives 300 of the two groups of weeding components 400 are symmetrically distributed;

[0032] The main body of the shaft body 100 is a hexagonal shaft, and the shaft body 100 is disposed through the middle of the first mounting plate 200 of the weeding assembly 400 and is welded and fixed to the first mounting plate 200, so that the shaft body 100 and the first mounting plate 200 are coaxially distributed;

[0033] The outer edge of the first mounting plate 200 includes six ends. The end edges of the first mounting plate 200 are provided with mounting portions 201. The mounting portions 201 are formed by bending the ends toward one side thereof, so that the outer side of the mounting portions 201 constitutes a mounting platform. The mounting portions 201 are used to connect and fix the weeding blade 300, fix the weeding blade 300 to the outer side of the weeding assembly 400, and the blade surfaces of the weeding blades 300 are arranged toward the same side.

[0034] Based on the above structure, the weeding knives 300 of the two groups of weeding assemblies 400 are staggered in the circumferential direction of the weeding mechanism body, that is, the installation angles of the two groups of weeding assemblies 400 are different. In this way, the weeding knives 300 of the two groups of weeding assemblies 400 are in alternating contact with the ground, so that the lawnmower is more stable during its movement.

[0035] Furthermore, the weeding knife 300 is tilted relative to the axis of the weeding component 400, that is, there is a certain length difference between the positions of the mounting portions 201 of the two first mounting plates 200 for mounting the same weeding component 400, so that the weeding knife 300 can form a certain tilt angle after being installed and fixed. The tilt angle is determined based on factors such as land conditions, equipment model and weight. Through the distribution effect of the tilt angle, the weeding knife 300 can have less contact with the ground during the weeding process, so that the weeding machine is lighter when walking, and it is also lighter and easier for users to hold and walk.

[0036] The weeding component 400 is rotatably mounted on the housing 900 via a rotating shaft, and the end of the rotating shaft is assembled through a bearing support. It is also connected to the engine of the weeder through a reducer, a transmission wheel, a transmission belt, etc. The front side and bottom of the housing 900 are open structures, so that the weeding component 400 can contact the grass and the ground through the opening structure to meet the weeding operation requirements.

[0037] The outer side of the housing 900 is rotatably connected to the adjustment mechanism, and the adjustment mechanism is used to adjust the height of the weeding assembly 400 from the ground, wherein:

[0038] The adjustment mechanism includes walking wheels 802, angle adjustment parts 803 and a bracket body 801. The bracket body 801 is made of round tube bending and welding. The middle part of the bracket body 801 is rotatably assembled with the outer shell 900. The bottom end of the bracket body 801 is installed with the two sets of walking wheels 802. The walking wheels 802 are located outside the two ends of the front side of the outer shell 900. The upper part of the bracket body 801 is connected to the outer shell 900 through the angle adjustment part 803. The angle adjustment part 803 includes a sleeve and a screw rod that are threadedly connected to each other. The sleeve is rotatably connected to the bracket body 801, and the end of the screw rod is rotatably connected to the outer shell 900. The length of the angle adjustment part 803 is controlled by rotating the hand wheel, so that the working height of the weeding component 400 can be adjusted by using the assembly length of the angle adjustment part 803.

[0039] according to Figure 6As shown: the weeding component 400 can also be replaced and assembled by a grass chopping component. The grass chopping component adopts the same shaft body 100 structure as the weeding component 400, and the overall matching appearance size. After replacement, the grass can be broken up by the grass chopping component; the outer side of the shaft body 100 of the grass chopping component is connected and fixed with three groups of radially evenly distributed mounting rods 501 through a second mounting plate 500, and 5-7 groups of fling knives 600 are installed on the outer side of each group of mounting rods 501. During operation, grass chopping can be performed by the rotating fling knives 600.

[0040] according to Figure 7 As shown: the weeding component 400 can also be replaced and assembled by a rotary tillage component. The rotary tillage component adopts the same shaft body 100 structure as the weeding component 400, and the overall matching appearance size. After the replacement, the ground can be rotary tilled by the rotary tillage component; a mounting seat 700 is welded on the outer side of the shaft body 100 of the rotary tillage component, and the outer side of the mounting seat 700 has three radially evenly distributed mounting ports, and a rotary tillage blade 701 is fixed in the mounting port. During the operation, rotary tillage can be performed by rotating the rotary tillage blade 701.

[0041] The grass-chopping component, the rotary tillage component and the weeding component 400 can realize parallel replacement of the functional components of the lawnmower, making the lawnmower more convenient to use.

[0042] The above description is only a preferred implementation mode of the present utility model. As long as the technical solution of the purpose of the present utility model is achieved by basically the same means, it belongs to the protection scope of the present utility model.
