Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rotary tiller technology, specifically, it relates to a rotary tiller auger and a rotary tiller. Background Technology
[0002] Ridging refers to creating raised ridges in farmland by piling up soil. This practice has many benefits and applicable conditions in agricultural planting, especially for flue-cured tobacco fields. Ridging tobacco fields can prevent waterlogging and drought, reduce disease, increase soil temperature, facilitate mulching, and help control planting density. Large-scale ridge preparation for flue-cured tobacco fields generally uses rotary tillers equipped with augers. During use, the rotary tiller auger is prone to wear and damage due to friction with the soil, requiring replacement with a new auger or a auger with different sawtooth parameters depending on the soil conditions. Currently, when the rotary tiller auger is damaged or needs to be replaced with a new one, the entire auger must be removed and replaced with a new one, which is very inconvenient, costly, and labor-intensive.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] like Figure 1 , Figure 2 As shown, this embodiment provides a rotary tillage auger, including a helical shaft 1 and helical blades 2 spirally wound on the helical shaft 1. The outer edge of the helical blades 2 is provided with helical blades 3 extending in the helical direction. The helical blades 3 are detachably connected to the helical blades 2, and the outer end face of the helical blades 3 is provided with a serrated structure extending beyond the outer end face of the helical blades 2. The helical blades 3 and the helical blades 2 are detachably connected by bolts or pins. The helical blades 2 are wound axially along the helical shaft 1.
[0025] The rotary tiller auger based on the above structure is installed on a rotary tiller for tilling and ridging fields. The spiral blade 3 is detachably installed on the spiral blade 2. When the rotary tiller auger needs to be replaced, if it is worn or damaged, or if a rotary tiller auger with different sawtooth parameters needs to be replaced, simply remove the spiral blade 3 from the spiral blade 2 and then install the replacement spiral blade 3 on the spiral blade 2. There is no need to replace the entire rotary tiller auger, making replacement safe, convenient, and cost-effective, while also reducing the labor intensity of operators. The rotary tiller auger of this application is installed on a rotary tiller, and the spiral blade 3 is easy to replace, making it particularly suitable for tilling and ridging tobacco fields.
[0026] As one possible implementation method, such as Figure 1 , Figure 2 As shown, the spiral blade 3 and the spiral blade 2 are provided with corresponding first bolt holes, and the spiral blade 3 and the spiral blade 2 are threadedly connected to the first nut by the first bolt 4 passing through the corresponding first bolt holes.
[0027] To replace the helical blade 3, loosen each first nut sequentially, remove the first bolt 4 from the first bolt hole, and remove the helical blade 3. Install the helical blade 3 to be replaced, aligning the first bolt holes on the helical blade 3 with those on the helical blade 2. After passing the first bolt 4 through the first bolt holes of both the helical blade 3 and the helical blade 2, tighten the first nut. Use a tool such as a wrench to tighten each first nut sequentially until the sidewall of the helical blade 3 fits tightly against the sidewall of the helical blade 2. The helical blade 3 and the helical blade 2 are bolted together, ensuring a secure and reliable connection that facilitates disassembly and installation during replacement and maintenance. Install a bolt washer between the first bolt 4 and the helical blade 2 for further tightening.
[0028] As one possible implementation, the spiral blade 3, the spiral vane 2, and the spiral shaft 1 are all steel structural components.
[0029] The steel spiral blades 3, spiral blades 2, and spiral shaft 1 have high strength, good mechanical properties, and good durability, which increases the service life of the rotary tillage auger.
[0030] As one possible implementation, the outer walls of the spiral blade 3, the spiral vane 2, and the spiral shaft 1 are all coated with a protective coating.
[0031] All surfaces are coated with protective coatings such as paint, 35% WC induction brazing, or diamond induction brazing to protect the spiral blades, spiral vanes, and spiral shaft, thereby improving their hardness, wear resistance, oxidation resistance, and corrosion resistance, enhancing their protective performance, and extending the service life of the rotary tiller auger.
[0032] As one possible implementation method, such as Figure 1 , Figure 2 As shown, the spiral blade 3 is composed of multiple segmented structures.
[0033] A single spiral blade 3 consists of at least two sections, such as two, three, or four sections, which facilitates the installation and removal of the spiral blade 3, allows for a tighter fit between the sidewall of the spiral blade 3 and the sidewall of the spiral blade 2, and improves the overall integrity and stability of the rotary tillage auger. There are gaps between adjacent spiral blade sections 3 for easy installation.
[0034] As one possible implementation method, such as Figure 2 As shown, the sidewall of the spiral blade 2 is provided with soil-crushing blades 5, and multiple soil-crushing blades 5 are evenly arranged along the spiral direction of the spiral blade 2.
[0035] At least two soil-breaking blades 5 are provided on the side wall of the spiral blade 2, such as two, three, four, or more integers. Further, four soil-breaking blades 5 are evenly distributed in one ring of spiral blades 3. The soil-breaking blades 5 are used to break up the soil, which is beneficial for tillage. Simultaneously, the cutting edges of the soil-breaking blades 5 cut into the soil, providing better grip and further facilitating tillage and ridging, reducing the pushing force required by the operator and lowering the operator's labor intensity. The soil-breaking blades 5 and the spiral blades 3 are located on the same side wall of the spiral blade 2, or opposite each other on the two side walls of the spiral blade 2.
[0036] As one possible implementation method, such as Figure 2 As shown, the soil-crushing blade 5 is detachably mounted on the side wall of the spiral blade 2.
[0037] The soil crushing blade 5 is detachably connected to the spiral blade 2, making it easy to maintain and replace the worn soil crushing blade 5 separately.
[0038] As one possible implementation method, such as Figure 2 As shown, the soil-crushing blade 5 includes a soil-crushing part and a connecting part. The connecting part and the soil-crushing part are bent. The connecting part and the spiral blade 2 are provided with second bolt holes. The connecting part and the spiral blade 2 are threadedly connected to the second nut by a second bolt 6 passing through the corresponding second bolt hole.
[0039] The second bolt holes on the connecting part of the soil-crushing blade 5 are aligned one-to-one with the second bolt holes on the spiral blade 2. The connecting part of the soil-crushing blade 5 and the spiral blade 2 are bolted together, ensuring a stable, safe, and reliable connection that facilitates disassembly and installation during replacement and maintenance. Furthermore, the connecting part of the soil-crushing blade 5 has at least two second bolt holes, with the second bolt holes on the spiral blade 2 and the second bolt 6 corresponding one-to-one with the second bolt holes on the connecting part of the soil-crushing blade 5, making the connection between the soil-crushing blade 5 and the spiral blade 2 even more secure. The connecting part of the soil-crushing blade 5 is bolted to the spiral blade 2, and the soil-crushing blade 5, including the soil-crushing portion, is bent away from the spiral blade 2. The soil-crushing portion of the soil-crushing blade 5 is lower than the outer end of the spiral blade 3. A bolt washer is installed between the second bolt 6 and the spiral blade 2 for further tightening.
[0040] As one possible implementation method, such as Figure 2 As shown, the soil-crushing blade 5 and the spiral blade 3 are respectively disposed on the two side walls of the spiral blade 2.
[0041] The soil crushing blade 5 and the spiral blade 3 are respectively installed on the two side walls of the spiral blade 2. The soil crushing blade 5 is installed close to the outer edge of the spiral blade 2, which makes it easy to adjust the installation position of the soil crushing blade 5 and will not interfere with the installation of the spiral blade 3, thus facilitating installation.
[0042] like Figure 1 , Figure 2 As shown, a rotary tiller based on the above-described rotary tiller auger structure includes a frame, a drive mechanism, a rotary tiller shaft, a ditching and ridging device, and the aforementioned rotary tiller auger. The drive mechanism is mounted on the frame, and the rotary tiller shaft is horizontally rotatably mounted at the lower end of the frame. The drive mechanism drives the rotary tiller shaft to rotate. Two rotary tiller augers are mounted at both ends of the rotary tiller shaft, with the two rotary tiller augers rotating in opposite directions. The ditching and ridging device is located behind the two rotary tiller augers.
[0043] The rotary tiller is equipped with the aforementioned rotary auger for tilling and ridging fields. The auger blades 3 are detachably mounted on the auger blades 2. Replacement is only required by replacing the auger blades 3, eliminating the need to replace the entire rotary auger. This makes replacement safe, convenient, and cost-effective, reducing the labor intensity of operators. The auger blades 3 of the rotary tiller described in this application are easy to replace and are particularly suitable for tilling and ridging tobacco fields. The auger shaft 1 is a square tube, bolted and fitted onto the rotary tiller shaft. The drive mechanism includes a diesel engine and a gearbox. Power from the diesel engine is transmitted from the output shaft to the gearbox, which drives the rotary tiller shaft at the lower end of the frame to rotate, thereby rotating the rotary auger and turning the soil to the ridging device.
[0044] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
