Description

Technical Field

[0001] This utility model relates to the field of micro-tiller technology, and in particular to a rotary tiller blade with a grass-chopping function. Background Technology

[0002] Mini tillers, when equipped with different accessories, can perform tasks such as ditching, ridging, hilling, spraying pesticides, sowing, rotary tilling, loosening soil, inter-row cultivation, deep tilling, weeding, fertilizing, harvesting, mulching, root and tuber harvesting, covering soil, and field transport. Mini tillers are widely sold throughout China and have received consistent praise from farmers. The main unit of a mini tiller consists of an engine, transmission and reduction gears, and drive wheels. The engine's power is transmitted to the drive wheels via the transmission and drive wheel drive mechanism, enabling the mini tiller to move on the ground. Removing the drive wheels and replacing them with rotary tillers allows for rotary tilling. With other parts added, it can also perform tasks such as ditching, ridging, and weeding. Furthermore, when using auxiliary machinery such as hilling and spraying equipment, the engine power is connected to these machines via a power take-off mechanism.

[0003] When a mini tiller is working, weeds or grass roots often get tangled in the blades, reducing the tiller's efficiency and directly affecting the blades' performance. In severe cases, it can cause the engine to stall and malfunction. If one blade gets tangled and causes the shaft to jam, the other blade can still rotate, potentially causing the tiller to tip over if the operator is not paying attention. This poses a significant threat to the operator, as the high-speed rotating blades could be extremely dangerous. To address this technical problem, this application proposes a rotary tiller blade with a grass-chopping function. Utility Model Content

[0022] 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.

[0023] Reference Figures 1-2 This utility model provides an embodiment of a rotary tiller blade with a grass-chopping function, including a main support 1. The main support 1 serves as the main body of the rotary tiller and connects various components. The main support 1 is connected to a connecting shaft 4 via a power assembly, which drives the connecting shaft 4 to rotate. The outer wall of the connecting shaft 4 is connected to a protective shell 5 via a mounting assembly, which allows the protective shell 5 to be mounted on the connecting shaft 4. A baffle 10 is fixedly connected to the outer wall of the protective shell 5. The connecting shaft 4 drives the baffle 10 on the protective shell 5 to rotate, thereby preventing weeds from getting tangled in the internal shaft tube. A rotating shaft 11 is fixedly connected to the inner wall of the connecting shaft 4. The rotation of the connecting shaft 4 drives the rotating shaft 11 to rotate, thereby driving the arc-shaped tiller blade 13 and the weeding blade to rotate. Multiple mounting brackets 12 are fixedly connected to the outer wall of the rotating shaft 11. Arc-shaped tiller blades 13 are installed on the outer wall of each mounting bracket 12. The arc-shaped tiller blades 13 can be installed on the rotating shaft 11 through the mounting brackets 12. A first weeding blade 14 is fixedly connected to the end of the outer wall of the rotating shaft 11. Multiple second weeding blades 15 are fixedly connected to the outer wall of the rotating shaft 11. Weeds can be broken up by the two different weeding blades, while improving the safety of the side wall of the micro tiller.

[0024] Reference Figures 3-4 The power assembly includes an engine 2 mounted on the top side of the main support 1, a power assembly 3 mounted on the outer wall of the engine 2, and connecting shafts 4 mounted on both sides of the power assembly 3. By starting the engine 2, the power assembly 3 will transmit the power of the engine 2 to the connecting shafts 4, thereby driving the connecting shafts 4 to rotate.

[0025] The mounting components include a second mounting hole 7 on the inner wall of the connecting shaft 4 and a first mounting hole 6 on the inner wall of the protective shell 5. A plug 8 is provided on the inner walls of both the first mounting hole 6 and the second mounting hole 7. A wire 9 is provided on the bottom side of the plug 8. The plug 8 is L-shaped. Inserting the plug 8 into the second mounting hole 7 on the inner wall of the connecting shaft 4 and the first mounting hole 6 on the inner wall of the protective shell 5 will fix the protective shell 5 onto the connecting shaft 4. Tightening the plug 8 by inserting the wire 9 into the round hole on the bottom side of the plug 8 will prevent it from loosening.

[0026] The second weeding blade 15 is located on both sides of the mounting bracket 12 to evenly break up the weeds in front. The top side of the main bracket 1 is rotatably connected to the handle 17 to facilitate the operator's operation of the micro-tiller. Mudguards 16 are fixedly connected to both sides of the main bracket 1 to prevent a large amount of mud and sand from splashing when the micro-tiller is working. A support frame 18 is installed at the rear end of the main bracket 1. When the operator stops working, the support frame 18 is inserted into the soil to maintain the stability of the micro-tiller. The bottom side of the mudguard 16 is located on the top of the second weeding blade 15 to prevent mud and sand from splashing when the curved tiller blade 13 and the weeding blade are working.

[0027] Working principle: By inserting the plug 8 into the mounting hole 7 on the inner wall of the connecting shaft 4 and the mounting hole 6 on the inner wall of the protective shell 5, the protective shell 5 can be fixed to the connecting shaft 4, and the connecting shaft 4 is connected to the power assembly 3. Inserting and tightening the wire 9 into the round hole on the bottom side of the plug 8 prevents it from loosening. The curved tiller blade 13 is mounted on the rotating shaft 11 via the mounting bracket 12. Starting the engine 2 drives the power assembly 3, which in turn rotates the connecting shaft 4. The rotation of the connecting shaft 4 drives the rotating shaft 11, which in turn drives the curved tiller blade 13 and the weeding blade to rotate at high speed for operation. The curved tiller blade 13 and the weeding blade have thinner blade edges and thicker backs, making them more effective at breaking up weeds and loosening the soil. The second weeding blade 15 has its blade curved to both sides to achieve a larger area of ​​weed breaking. The first weeding blade 14... The blades bend towards the tiller, increasing the area for shredding grass while improving safety on both sides of the tiller. This prevents important items from being damaged by the weeding blades on either side of the tiller. The rotation of the connecting shaft 4 causes the protective shell 5 to rotate, which in turn rotates the baffle 10 fixedly connected to the outer wall of the protective shell 5. This breaks up weeds near the shaft tube, preventing weeds from tangling inside the shaft tube and causing jamming. After the machine is started, the operator can control the tiller using the handle 17. The mudguards 16 on both sides of the tiller can block soil thrown up by the rotation of the curved tiller blades 13 and the weeding blades. When the operator pauses work, the support frame 18 is inserted into the soil to maintain the tiller's stability. When the work is finished, the bolt 8 can be removed from the protective shell 5 and the connecting shaft 4 by unscrewing the wire 9, allowing the entire weeding blade assembly to be removed for easy cleaning.

[0028] 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.
