Description

Technical Field

[0001] The present application relates to the technical field of agriculture, and specifically relates to a rotary tiller. Background Art

[0002] Agriculture is the activity of humans to produce food, vegetables, fruits, and other crops and livestock, covering the entire process from soil management to harvesting and marketing. Among them, agriculture includes the soil that needs to be planted, and the soil needs to be repaired before planting. Usually, a rotary tiller can be used. The rotary tiller is used to loosen and mix the soil, so as to improve the air permeability and water penetration ability of the soil, and create a better environment for the growth of crops.

[0003] However, among the current rotary tiller equipment we use, the equipment includes rotary tillage blades inside, and the rotary tillage blades are in contact with the soil. Thus, the rotary tillage blades rotate continuously, so that the soil can be overturned and loosened. However, after the soil is loosened, the surface of the soil will be uneven. In order not to affect subsequent sowing and irrigation treatments, it is necessary to level the surface of the soil.

[0004] Therefore, it is necessary to provide a rotary tiller to solve the above problems. Utility Model Content

[0025] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0027] As Figures 1-4 shown, this application provides a rotary tiller, which includes a soil-turning component 10 and a soil-smoothing component 20 fixedly installed on the soil-turning component 10. Among them, both the soil-turning component 10 and the soil-smoothing component 20 need to be in contact with the soil. At the same time, the soil-turning component 10 is used for loosening the soil, and the soil-smoothing component 20 is used for surface smoothing of the soil loosened by the soil-turning component 10, so as to facilitate subsequent sowing and irrigation of the soil.

[0028] The soil-turning component 10 includes a main body 11, and a moving wheel 16 is arranged on the main body 11. At the same time, the moving wheel 16 can be in contact with the soil or the ground, so that the whole soil-turning component 10 can be transported or moved during work through the moving wheel 16.

[0029] A motor 13 is fixedly installed on the main body 11. At the same time, a drive shaft 14 is fixedly installed on the output shaft of the motor 13. A chain drive module 18 is fixedly installed on the main body 11. One end of the chain drive module 18 can be connected to the drive shaft 14, and a rotary tiller 17 is fixedly installed at the other end of the chain drive module 18. The rotary tiller 17 can contact the soil. Thus, when the motor 13 is started, it will drive the drive shaft 14 to rotate. At this time, the chain drive module 18 will drive the rotary tiller 17 to rotate, so that the soil can be loosened after the rotary tiller 17 contacts the soil.

[0030] The chain drive module 18 includes two sets of gear disks (not shown in the figure), and a chain (not shown in the figure) is engaged between the two sets of gear disks. One set of gear disks is fixedly connected to the drive shaft 14, and the other set of gear disks is fixedly connected to the shaft of the rotary tiller 17.

[0031] At the same time, a sealing cover 15 is fixedly installed on the outside of the main body 11. The sealing cover 15 is located outside the chain drive module 18. The sealing cover 15 is used to seal the chain drive module 18. Thus, the chain drive module 18 can prevent dust, soil, and moisture from entering through the sealing cover 15, and further protect the chain drive module 18 from the influence of the external environment and improve stability.

[0032] A support frame 12 is fixedly installed on the main body 11. The support frame 12 can be connected to an external power system, so that the whole equipment can move and work on the soil through the external power system.

[0033] The leveling assembly 20 includes a baffle 21. The baffle 21 is fixedly installed on the main body 11. At the same time, the baffle 21 is located above the rotary tiller 17. The baffle 21 can block and seal the upper part of the rotary tiller 17, so that the soil splashed by the rotary tiller 17 during rotation can be blocked, and further prevent the soil from spreading everywhere and improve the sanitation effect.

[0034] The baffle 21 is provided with a fixing strip 23. A hinge rod 25 is hinged on the fixing strip 23. At the same time, a pressing plate 24 is fixedly installed on the hinge rod 25. The pressing plate 24 can contact the soil. Thus, after the soil is turned over by the rotary tiller 17, as the equipment moves continuously, the pressing plate 24 will continuously pass over the soil, so that the surface of the turned-up soil can be leveled, ensuring the flatness of the soil surface, and further facilitating the subsequent sowing and irrigation of the soil by the equipment.

[0035] And a torsion spring 210 is arranged between the fixing strip 23 and the pressing plate 24, so that the pressing plate 24 can apply a continuous downward pressing force to the soil it contacts through the torsion spring 210, further increasing the contact force between the pressing plate 24 and the soil and improving the leveling effect of the pressing plate 24 on the soil.

[0036] At both ends of the pressing plate 24, side plates 27 are provided. The side plates 27 can contact the ends of the soil. When the device loosens the soil, the side plates 27 can scrape the two ends of the soil, so as to avoid large-scale sliding of the two ends of the soil, and then ensure the stability of the two ends of the soil. And a threaded strip a28 is fixed on the side plate 27, and the threaded strip a28 is threadedly connected to the inside of the pressing plate 24. Thus, the side plate 27 can rotate on the pressing plate 24 through the threaded strip a28. At this time, the distance between the side plate 27 and the pressing plate 24 can be enlarged, so that the side plate 27 can scrape soils with different widths, and the use effect of the side plate 27 is improved.

[0037] A moving groove 22 is formed on the baffle 21. At the same time, a threaded strip b211 is fixedly installed on the fixing strip 23. The threaded strip b211 can pass through the moving groove 22. At the same time, a threaded cap 29 is threadedly connected to the outside of the threaded strip b211. When the threaded cap 29 rotates on the threaded strip b211, the threaded cap 29 can fix and limit the fixing strip 23 after contacting the outer wall of the baffle 21.

[0038] A handle 26 is fixedly installed on the fixing strip 23. After the threaded cap 29 is loosened, the threaded strip b211 can be adjusted inside the moving groove 22. Thus, the staff can adjust the position of the fixing strip 23 by pulling the handle 26, and then the pressing plate 24 can be retracted on the baffle 21, so as to prevent the pressing plate 24 from contacting the ground and being damaged during equipment transportation.

[0039] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
