Description

Technical Field

[0001] This utility model relates to the field of rotary tillage equipment technology, and in particular to an anti-tangling rotary tillage structure and a rotary tiller. Background Technology

[0002] In modern agriculture, rotary tillers are a common type of tillage equipment. However, due to the abundance of weeds and other debris in farmland, the rotary tiller's shaft easily becomes entangled with these materials during tillage, leading to decreased efficiency, increased power consumption, and the difficulty and time-consuming removal of the entangled debris. Furthermore, existing hand-held tractor-style rotary tillers often leave the land uneven, requiring subsequent leveling operations, further increasing labor and time costs. Please see [link to relevant documentation]. Figure 1 In rural areas, hand-held tractor-type rotary tillers are still very common. However, these tillers require foot control, and when the foot is pressed down hard, the operator's body will tilt significantly, posing a certain safety hazard.

[0003] Therefore, it is necessary to improve existing rotary tillage devices to enhance the anti-tangling effect of the rotary tillage structure. Simultaneously, it is necessary to improve existing hand-held tractor-type rotary tillers, as well as large, medium, and small rotary tillers, to improve land leveling efficiency and operational safety. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-tangling rotary tillage structure and rotary tiller to address the above-mentioned problems, thereby solving the technical problems of traditional rotary tillers having poor anti-tangling effect and being unable to level the field, while the hand-held tractor type has safety issues when using foot to control the direction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An anti-tangling rotary tillage structure includes a housing, a rotary shaft, a plurality of rotary blade sets, and two end cutting blades. The housing opens downwards, and the rotary shaft is rotatably mounted inside the housing. The rotary blade sets are spaced alternately along the central axis of the rotary shaft. Each rotary blade set includes at least one left-curved blade and one right-curved blade. The left-curved blade of one rotary blade set and its adjacent, facing right-curved blade of the same rotary blade set are staggered, and the right-curved blade of one rotary blade set and its adjacent, facing left-curved blade of the same rotary blade set are staggered. The end cutting blades are respectively mounted inside the housing and located at both ends of the rotary shaft. One end cutting blade is staggered with the left-curved blade of a rotary blade set located at the outermost end of the rotary shaft, and the other end cutting blade is staggered with the right-curved blade of another rotary blade set located at the outermost end of the rotary shaft.

[0007] Furthermore, it also includes several anti-winding rods, which are arranged parallel to the central axis of the rotary tiller shaft. The several anti-winding rods are arranged alternately around the outer periphery of the rotary tiller shaft, and the anti-winding rods are arranged alternately with the outer periphery of the rotary tiller shaft; the two ends of the anti-winding rods are provided with semi-circular arc parts.

[0008] Furthermore, the lower part of the end grass cutter is provided with a sharp blade, one end of the end grass cutter is provided with a mounting part, and the other end is provided with a pointed tip.

[0009] An anti-tangling rotary tiller includes a body and an anti-tangling rotary tilling structure.

[0010] Furthermore, a seat, a steering wheel, and a footrest are provided on the upper rear part of the machine body, and a steering wheel is provided on the lower rear part of the machine body. The steering wheel is connected to the steering wheel. A control pedal is provided on the front part of the footrest.

[0011] Furthermore, the middle part of the control pedal is rotatably connected to the upper part of the outer casing, one end of the control pedal is connected to the control structure of the machine body through a connector, and the other end of the control pedal is set as a foot pedal.

[0012] Furthermore, a flattening structure is provided at the rear of the machine body. The flattening structure includes a flattening plate, a long connecting rod, and a lifting operation structure. The flattening plate is installed at the rear of the machine body. One end of the long connecting rod is fixedly connected to the flattening plate, and the other end is rotatably connected to the upper part of the outer shell. The lifting operation structure is installed at the rear of the machine body and connected to the flattening plate. The lifting operation structure can control the lifting and lowering of the flattening plate.

[0013] Furthermore, the lifting operation structure includes an operating lever, a rotating lever, a first connecting rod, a second connecting rod, and a slot. The rotating lever is rotatably connected to the rear of the machine body. One end of the operating lever is fixedly connected to one end of the rotating lever, and the operating lever and the rotating lever are perpendicular to each other. The other end of the operating lever can be pressed down and locked into the slot fixed on the machine body. One end of the first connecting rod is fixedly connected to the outer periphery of the rotating lever, and the first connecting rod and the rotating lever are perpendicular to each other. One end of the second connecting rod is hinged to the other end of the first connecting rod, and the other end is hinged to the upper part of the flat plate.

[0014] Furthermore, the long connecting rods are arranged in pairs at both ends of the flat plate.

[0015] Furthermore, a sunshade is also provided on the upper rear part of the machine body.

[0016] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model relates to an anti-tangling rotary tillage structure. It features several rotary tillage blades arranged in a staggered pattern of left- and right-facing curved blades. During operation, these blades form a closed tillage path along the outer circumference of the rotary tillage shaft, preventing weeds from tangling around the shaft's center. End-cutting blades at both ends cut any weeds tangled around the shaft, preventing excessive tangling and facilitating the compression of the cut weeds into the soil for organic fertilizer. A leveling structure at the rear of the rotary tiller smooths the tilled field, reducing subsequent leveling work. This improvement over traditional hand-held tractor-style rotary tillers, using a hand-operated steering wheel, reduces operator safety hazards. Based on the above, this utility model solves the technical problems of traditional rotary tillers, such as poor anti-tangling performance and inability to level fields, as well as the safety risks associated with foot-operated steering in hand-held tractor-style rotary tillers.

[0018] 2. By incorporating an anti-tangling rod, this utility model prevents weeds that might enter the area enclosed by the rotary tiller shaft and form a closed rotary tillage path from being directly tangled in the rotary tiller shaft, thereby further improving the anti-tangling effect.

[0019] 3. This utility model can directly improve the existing hand-held tractor-type rotary tiller, improve the use effect of the hand-held tractor-type rotary tiller, reduce the equipment replacement cost, and reduce the cost of rotary tilling the field. Attached Figure Description

Example 1

[0030] Please see Figure 2 and Figure 3A rotary tillage structure 200 for preventing tangling includes a housing 21, a rotary shaft 22, several rotary blade sets 23, and two end cutting blades 24. The housing 21 opens downwards, and the rotary shaft 22 is rotatably mounted inside the housing 21. The rotary blade sets 23 are spaced alternately along the central axis of the rotary shaft 22. Each rotary blade set 23 consists of three blades, including at least one left-curved blade 231 and one right-curved blade 232. The left-curved blade 231 of the rotary blade set 23 and the right-curved blade of its adjacent and facing rotary blade set 23 are also included. The rotary tiller blades 232 are staggered, with the right-curved blade 232 of the rotary tiller blade set 23 and the left-curved blade 231 of its adjacent and facing rotary tiller blade set 23 staggered. The end grass-cutting blades 24 are respectively installed inside the housing 21 and located at both ends of the rotary tiller shaft 22. One end grass-cutting blade 24 is staggered with the left-curved blade 231 of a rotary tiller blade set 23 located at the outermost end of the rotary tiller shaft 22, and the other end grass-cutting blade 24 is staggered with the right-curved blade 232 of another rotary tiller blade set 23 located at the outermost end of the rotary tiller shaft 22. Specifically, the rotary tiller shaft 22 is provided with several blade holders 233, and the left-curved blade 231 and the right-curved blade 232 are detachably connected to the rotary tiller shaft 22 through corresponding blade holders 233. The rotary tillage blade assembly 23 is equipped with one left-curved blade 231 and two right-curved blades 232, or two left-curved blades 231 and one right-curved blade 232. The mid-plane distance between the central planes of the vertical rotary tillage shafts 22 of the two rotary tillage blade assemblies 23 is 8 cm. The curved end of the left-curved blade 231 extends more than 4 cm to the left along the mid-plane of the rotary tillage blade assembly 23, and the curved end of the right-curved blade 232 extends more than 4 cm to the right along the mid-plane of the rotary tillage blade assembly 23. By having several rotary tillage blade sets 23 with left-facing curved blades 231 and right-facing curved blades 232 arranged alternately, the left-facing curved blades 231 and right-facing curved blades 232 can form a closed rotary tillage path along the outer periphery of the rotary tillage shaft 22 during operation. The rotary tillage blade sets 23 can prevent weeds from getting tangled in the middle of the rotary tillage shaft 22. The end cutting blades 24 set at both ends can cut off the weeds that are tangled in the ends of the rotary tillage shaft 22, preventing them from getting tangled in large quantities. The leveling structure 15 set at the rear of the rotary tiller can level the field after rotary tillage, reducing the need for subsequent leveling work.

[0031] In this embodiment, a plurality of anti-winding rods 25 are also included. The anti-winding rods 25 are arranged parallel to the central axis of the rotary tiller 22, and are arranged alternately around the outer periphery of the rotary tiller 22. Specifically, there are two to three groups of anti-winding rods 25, with two rods in each group. Semi-circular arc elements can be provided at both ends of the anti-winding rods 25, allowing the two rods in the same group to form a closed loop. The anti-winding rods 25 are fixedly connected to the blade holder 233 by welding. By providing the anti-winding rods 25, weeds that might enter the area enclosed by the closed rotary tillage path around the outer periphery of the rotary tiller 22 are blocked by the anti-winding rods 25 and fall off due to gravity, preventing the weeds from directly entangled on the rotary tiller 22, thus further improving the anti-winding effect.

[0032] In this embodiment, the end grass cutter 24 has a sharp blade 241 at its lower part, a mounting part 242 at one end of the end grass cutter 24, and a pointed tip at the other end. The angle between the sharp blade 241 and the central axis of the rotary tiller 22 is 45°. The pointed tip is located within the closed rotary tillage path formed by the rotation of the rotary tiller blade assembly 23, and outside the closed rotary tillage path formed by the rotation of the anti-winding rod 25. Example 2

[0033] Please see Figure 4 and Figure 5 An anti-winding rotary tiller includes a body 100 and an anti-winding rotary tillage structure 200. It can directly improve existing hand-held tractor-type rotary tillers, enhance their performance, reduce equipment replacement costs, and lower field tillage costs. It is also applicable to the improvement and use of large, medium, and small rotary tillers.

[0034] In this embodiment, a seat 11, a steering wheel 12, and a footrest 13 are provided on the upper rear part of the machine body 100, and a steering wheel 14 is provided on the lower rear part of the machine body 100. The steering wheel 12 is connected to the steering wheel 14. A control pedal 17 is provided at the front of the footrest 13. The middle part of the control pedal 17 is rotatably connected to the upper part of the outer casing 21. One end of the control pedal 17 is connected to the control structure of the machine body 100 through a connector, and the other end of the control pedal 17 is set as a footrest. Specifically, there are four control pedals 17, including a clutch pedal, a left turn pedal, a right turn pedal, and an accelerator pedal. Each control pedal 17 is connected to the corresponding control point of the machine body 100 via a connecting wire rod. Based on the above configuration, the hand-held tractor-type rotary tiller can be improved by using a hand-operated steering wheel 12 to reduce the safety hazards for the operator.

[0035] In this embodiment, a flattening structure 15 is also provided at the rear of the machine body 100. The flattening structure 15 includes a flattening plate 151, a long connecting rod 152, and a lifting structure. The flattening plate 151 is installed at the rear end of the machine body 100. One end of the long connecting rod 152 is fixedly connected to the flattening plate 151, and the other end is rotatably connected to the upper part of the outer shell 21. The lifting operation structure is installed at the rear of the machine body 100 and connected to the flattening plate 151. The lifting operation structure can control the lifting of the flattening plate 151. Specifically, the lifting operation structure includes an operating lever 153, a rotating lever 154, a first connecting rod 155, a second connecting rod 156, and a slot 157. The rotating lever 154 is rotatably connected to the rear of the machine body 100. One end of the operating lever 153 is fixedly connected to one end of the rotating lever 154, and the operating lever 153 and the rotating lever 154 are perpendicular to each other. The other end of the operating lever 153 can be pressed down and locked into the slot 157 fixed on the machine body 100. One end of the first connecting rod 155 is fixedly connected to the outer periphery of the rotating lever 154, and the first connecting rod 155 and the rotating lever 154 are perpendicular to each other. One end of the second connecting rod 156 is hinged to the other end of the first connecting rod 155, and the other end is hinged to the upper part of the flat plate 151. Long connecting rods 152 are arranged in pairs at both ends of the flat plate 151. During leveling, the operating lever 153 is disengaged from the slot 157, and the leveling plate 151 automatically lowers for leveling due to gravity. When leveling is not required, pressing down the operating lever 153 causes the rotating lever 154 to lift the end of the first connecting rod 155, which in turn causes the second connecting rod 156 to pull the leveling plate 151 upwards. By incorporating a leveling structure 15 at the rear of the rotary tiller, the tilled field can be leveled, reducing subsequent leveling work.

[0036] In this embodiment, a sunshade 16 is also provided on the upper part of the rear of the body 100 for sunshade and rain protection.
