Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain planting, in particular to a soil turning device used for grain planting. Background Art
[0002] Turning the soil during grain planting helps the plant roots absorb oxygen and respire. The energy released can be used by the roots to absorb inorganic salts in the soil, which is beneficial to plant growth. Turning the soil can improve the soil structure, enhance the soil's air permeability and water and fertilizer retention, create good conditions for plant growth, and promote root growth. After turning the soil, the soil can be improved, which can enable the root system to grow well.
[0003] At present, some tilling devices are composed of a connecting column, several tilling rakes and a mechanical arm connector. When in use, the entire device is connected to the mechanical arm of the tractor through the mechanical arm connector, and then the tractor can turn the soil with several tilling rakes. However, if there are many weeds on the surface of the planting soil, the weeds need to be removed first. At present, weeders are usually used manually to remove the weeds on the surface of the soil, and then the soil is turned. However, this method is too cumbersome and complicated. The weeding process and the tilling process need to be separated and carried out with different tools, which is time-consuming and laborious. Moreover, when weeding, the cut weeds will still remain on the soil surface, which is not convenient for cleaning. Moreover, if too many weeds are mixed into the soil after turning, it will also have a certain impact on the subsequent grain planting. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] Example 1
[0021] Reference Figure 1-4 A soil turning device for grain planting includes a connecting column 1, a mechanical arm connecting piece 2 is fixedly connected to the connecting column 1, and the mechanical arm connecting piece 2 is used to be connected to the mechanical arm of a tractor. A plurality of soil turning rakes 3 are fixedly connected at equal intervals on one side of the connecting column 1, and a protective cover 4 is fixedly connected to the other side of the connecting column 1, and the protective cover 4 is an arc-shaped structure.
[0022] A bracket 5 is fixedly connected to the lower surface of the protective cover 4, and a connecting shaft 6 is rotatably connected to the bracket 5 through a rotating mechanism. Two grass cutting blades 7 are fixedly connected to the connecting shaft 6, and the two grass cutting blades 7 are respectively located on both sides of the bracket 5. The two grass cutting blades 7 are spiral blades, and the spiral directions of the two grass cutting blades 7 are opposite. First, the entire device is connected to the mechanical arm of the tractor through the mechanical arm connecting piece 2, and then, the several soil turning rakes 3 are adjusted to dig into the soil, and the two grass cutting blades 7 are placed in the weeds on the soil surface. Then, the tractor is turned on to carry the device forward on the soil, and the several soil turning rakes 3 will turn the soil. When the soil is turned, When encountering a place where weeds exist on the soil surface during the process, the rotating mechanism is started to drive the connecting shaft 6 to rotate, and the connecting shaft 6 drives the two grass cutting blades 7 to rotate synchronously in the same direction, and the two grass cutting blades 7 will cut the weeds on the soil surface. Moreover, since the two grass cutting blades 7 are spiral blades arranged in opposite spiral directions, the two grass cutting blades 7 will directly transport the cut weeds to both sides while cutting the grass. When the following several turning rakes 3 pass by and turn the soil, there will not be too many cut weeds left on the soil surface, which will prevent the cut weeds from mixing into the soil after turning the soil. Moreover, the weeds transported to both sides will be easier to clean and collect.
[0023] A plurality of crushing cones 12 are fixedly connected to the connecting shaft 6, and the plurality of crushing cones 12 are evenly distributed between the two grass cutting blades 7. When the rotating mechanism is started to drive the connecting shaft 6 to rotate, the connecting shaft 6 will also drive the plurality of crushing cones 12 to rotate at the same time. When encountering harder and larger clods on the soil surface during the soil turning process, the plurality of rotating crushing cones 12 will directly break up these harder and larger clods, thus facilitating the subsequent soil turning process.
[0024] Example 2
[0025] Reference Figure 1-4 As another preferred embodiment of the utility model, the difference from embodiment 1 is that the rotating mechanism includes a first gear 8, a motor 10 and a through port 11, the first gear 8 is fixedly connected to the middle position of the connecting shaft 6, and the motor 10 is fixedly connected to the upper surface of the protective cover 4. After the device is connected to the mechanical arm of the tractor, it is necessary to connect the motor 10 to the battery pack on the tractor through a wire, and a switch for controlling the operation of the motor 10 is provided on the wire.
[0026] One end of the output shaft of the motor 10 is fixedly connected with the second gear 9, and a through hole 11 is provided on the protective cover 4, and the second gear 9 passes through the through hole 11, and the second gear 9 is meshed with the first gear 8. When it is necessary to cut the weeds on the soil surface, by starting the motor 10, the motor 10 drives the second gear 9 to rotate, and the second gear 9 drives the first gear 8 to rotate, and the first gear 8 will drive the connecting shaft 6 to rotate, and the connecting shaft 6 will drive the two grass cutting blades 7 to rotate.
[0027] A baffle 13 is provided on the side of the first gear 8 close to the connecting column 1, and the upper end of the baffle 13 is fixedly connected to the connecting column 1. The baffle 13 is an arc-shaped structure. When the tractor moves forward with a plurality of tilling rakes 3 to till the soil, the baffle 13 can block the first gear 8 and the second gear 9 to prevent the plurality of tilling rakes 3 from splashing part of the soil onto the first gear 8 and the second gear 9 when tilling the soil, thereby affecting their normal use effect.
