[0016] Compared with the prior art, the present utility model has the following advantages:
[0017] The soil stirring device described in the utility model, through the settings of the soil-breaking roller, the stirring mechanism and the soil-turning roller, the rotating soil-breaking roller can break up the compacted soil, the turntable and the stirring rods in the stirring mechanism can stir the soil horizontally, and the soil-turning roller can turn the soil up and down. Compared with the way of manually stirring the soil, it reduces the labor intensity of personnel and improves the stirring effect and efficiency of the soil.
[0018] The soil-breaking rod is provided with soil-breaking teeth. When the first roller rotates to drive the soil-breaking rod to rotate, the soil-breaking teeth can penetrate into the soil to break up the compacted soil, reduce the particle size of the soil, and improve the uniformity of soil stirring.
[0019] Two adjacent soil-breaking rods are respectively arranged on the opposite sides of the outer periphery of the first roller and are arranged in a staggered manner along the length direction. While ensuring the soil-breaking effect on the soil, it reduces the rotation resistance of the soil-breaking roller, thus facilitating the excavation and crushing of the soil by the soil-breaking roller.
[0020] When the second roller rotates, the connecting part on the soil-turning piece can insert into the soil, and the extending part can turn the soil up and down, improving the uniformity of soil turning. The bending directions of the extending parts on two adjacent connecting parts are opposite, increasing the width of the soil turned by the soil-turning piece and further improving the stirring efficiency of the soil.
[0021] Through the settings of multiple stirring rods and multiple crushing rods, while the stirring rods stir the soil horizontally, the spaced arrangement of the crushing rods can further break up the lumped soil, thus further reducing the particle size of the soil, so that the stirring rods and the crushing rods can stir the soil more fully horizontally.
[0022] The lower end of the first rotating shaft is connected to the turntable, and a worm gear is provided at the upper end of the first rotating shaft. The two ends of the second rotating shaft are respectively rotatably connected to two side plates, and a worm meshing with the worm gear is provided on the second rotating shaft. Through the cooperative setting of the worm on the second rotating shaft and the worm gear on the first rotating shaft, when the second rotating shaft drives the first rotating shaft to rotate, due to the meshing of the worm gear and the worm, the first rotating shaft has a larger torque to ensure the smooth stirring of the stirring rods and the crushing rods in the soil.
[0023] The turntables are arranged at intervals, and multiple worms corresponding to the worm gears on each first rotating shaft are provided on the second rotating shaft. When the second rotating shaft rotates, the second rotating shaft can drive each turntable to rotate. Thus, the second rotating shaft can drive multiple turntables to rotate simultaneously, increasing the width and area of the soil stirred by the stirring mechanism, and thus improving the stirring efficiency of the soil.
[0024] The helix directions of two adjacent worms are opposite, making the rotation directions of two adjacent turntables opposite, avoiding the same rotation direction of each turntable, resulting in the repeated stirring of the soil, and improving the stirring efficiency of the stirring mechanism for the soil.
[0025] The driving mechanism is arranged on the outer side of one side plate. When the power source of the agricultural machinery drives the first roller to rotate through the driving sprocket, the first roller can drive the second rotating shaft and the second roller to rotate, thereby facilitating the driving of the soil-breaking roller, the soil-turning roller and each turntable to rotate. A connecting arm is arranged on the side plate to facilitate connection with the agricultural machinery. At the same time, a plurality of support frames are arranged on the top of the housing to support the second rotating shaft and ensure the smooth rotation of the second rotating shaft.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood in combination with specific situations.
[0044] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.
[0045] This embodiment relates to a soil stirring device, as Figure 1 . Figure 2 and Figure 3 shown. In terms of the overall structure, it includes a housing 1, a soil-breaking roller 2, a stirring mechanism, and a soil-turning roller 3 provided on the housing 1.
[0046] Among them, as Figure 4 shown, the soil-breaking roller 2 includes a first roller 201 whose two ends are rotatably connected to the side plate 101 of the housing 1, and a plurality of soil-breaking rods 202 provided on the first roller 201. As Figure 6As shown, the stirring mechanism includes a transmission component 4 provided at the top of the housing 1, a turntable 5 driven by the transmission component 4 and rotatably provided below the housing 1, and stirring rods 501 provided at the bottom of the turntable 5. As Figure 5 As shown, the soil-turning roller 3 includes a second roller 301 whose two ends are rotatably connected to the side plates 101 of the housing 1, and a plurality of soil-turning blades 302 provided on the second roller 301.
[0047] As described above, through the arrangement of the soil-breaking roller 2, the stirring mechanism and the soil-turning roller 3, the rotating soil-breaking roller 2 can break up the compacted soil, the turntable 5 and the stirring rods 501 in the stirring mechanism can stir the soil horizontally, and the soil-turning roller 3 can turn the soil up and down. Compared with the way of manually turning and stirring the soil, the labor intensity of personnel is reduced, and the turning and stirring effect and efficiency of the soil are improved.
[0048] Based on the above overall introduction, specifically, the soil turning and stirring device of this embodiment is connected to an agricultural machine, for example, connected to the tail of a tractor, and the soil turning and stirring device is connected to the power source on the agricultural machine and is driven by the power source.
[0049] In this embodiment, as Figure 4 As shown, the soil-breaking rods 202 are arranged at intervals along the length direction of the first roller 201. The end of the soil-breaking rod 202 is formed with soil-breaking teeth 203, and the tip of the soil-breaking teeth 203 faces the rotation direction of the first roller 201. Through the arrangement of the soil-breaking teeth 203, when the first roller 201 rotates to drive the soil-breaking rods 202 to rotate, the soil-breaking teeth 203 can penetrate into the soil to break up the compacted soil, reduce the particle size of the soil, improve the uniformity of soil stirring, and thus enhance the stirring effect on the soil.
[0050] In addition, in this embodiment, in the length direction of the first roller 201, two adjacent soil-breaking rods 202 are respectively arranged on the opposite sides of the outer circumference of the first roller 201 and are arranged in a staggered manner along the length direction. In the direction of travel of the soil turning and stirring device, the rotation of the first roller 201 can cause some soil-breaking rods 202 to break some soil. At this time, due to the interval arrangement of the soil-breaking rods 202, the land along the travel direction is dug by the soil-breaking rods 202 and the soil-breaking teeth 203 and presents a serrated shape. Subsequently, with the continuous rotation of the first roller 201, the other part of the soil-breaking rods 202 can dig the serrated protruding parts of the land, so that the soil-breaking roller 2 can break the land as the soil turning and stirring device of this embodiment advances.
[0051] It can be understood that if the soil-breaking rods 202 are not arranged with a dislocation along the length direction, a part of the land that has not been excavated and broken will remain in the gap between the soil-breaking rods 202. At the same time, if the soil-breaking rods 202 are not arranged with a dislocation along the length direction, the number of soil-breaking rods 202 that dig the soil simultaneously will increase, resulting in an increase in the rotational resistance of the soil-breaking roller 2. Therefore, by arranging two adjacent soil-breaking rods 202 on opposite sides of the outer circumference of the first roller 201 and with a dislocation along the length direction, while ensuring the soil-breaking effect, the rotational resistance of the soil-breaking roller 2 is reduced, which is beneficial for the soil-breaking roller 2 to excavate and crush the soil.
[0052] To improve the stirring effect on the soil, as Figure 5 shown, the soil-turning blades 302 of this embodiment are arranged at intervals along the length direction of the second roller 301. Among them, a plurality of connecting parts 303 that surround the second roller 301 and extend outward are formed on the soil-turning blade 302, and the ends of the connecting parts 303 are bent to form transverse extension parts 304. When the second roller 301 rotates, the connecting parts 303 can be inserted into the soil, and the extension parts 304 turn the soil up and down, improving the uniformity of soil stirring. At the same time, on the same soil-turning blade 302, the bending directions of the extension parts 304 on two adjacent connecting parts 303 are opposite, increasing the width of the soil turned by the soil-turning blade 302 and further improving the soil stirring efficiency.
[0053] To further reduce the particle size of the soil and improve the uniformity of soil stirring, as Figure 6 shown, a plurality of stirring rods 501 are provided on the turntable 5 of this embodiment, and a plurality of crushing rods 502 extending transversely are provided on each stirring rod 501. The crushing rods 502 are arranged at intervals along the length direction of the stirring rod 501. Through the arrangement of the plurality of stirring rods 501 and the plurality of crushing rods 502, while the stirring rods 501 stir the soil transversely, the interval arrangement of the crushing rods 502 can further break up the caked soil, thereby further reducing the particle size of the soil, so that the stirring rods 501 and the crushing rods 502 can stir the soil more fully transversely to improve the uniformity of soil stirring. In a specific implementation, the turntable 5 of this embodiment is triangular, and three stirring rods 501 are provided at the bottom of the turntable 5.
[0054] To drive the turntable 5 to rotate and drive the stirring rods 501 to stir the soil, the transmission assembly 4 of this embodiment includes a rotating seat 401 provided at the top of the housing 1, a first rotating shaft 402 rotatably connected to the rotating seat 401 and penetrating the housing 1 along the height direction, and a second rotating shaft 403 transversely provided at the top of the housing 1.
[0055] Among them, the lower end of the first rotating shaft 402 is connected to the turntable 5, and a worm gear 404 is provided at the upper end of the first rotating shaft 402. Both ends of the second rotating shaft 403 are respectively rotatably connected to two side plates 101, and a worm 405 meshing with the worm gear 404 is provided on the second rotating shaft 403. When the second rotating shaft 403 rotates, the second rotating shaft 403 drives the turntable 5 to rotate through the meshing of the worm gear 404 and the worm 405. Through the cooperative setting of the worm 405 on the second rotating shaft 403 and the worm gear 404 on the first rotating shaft 402, when the second rotating shaft 403 drives the first rotating shaft 402 to rotate, due to the meshing of the worm gear 404 and the worm 405, the first rotating shaft 402 has a relatively large torque to ensure that the stirring rod 501 and the crushing rod 502 smoothly stir in the soil, thereby ensuring the stirring effect of the stirring mechanism on the soil.
[0056] Specifically, the turntables 5 in this embodiment are configured to be multiple spaced along the width direction of the housing 1 to ensure that the stirring mechanism can cover the soil in the width direction of the soil turning device in this embodiment. And the first rotating shafts 402 are configured to be multiple corresponding one-to-one to each turntable 5, and multiple worms 405 corresponding one-to-one to the worm gears 404 on each first rotating shaft 402 are provided on the second rotating shaft 403. When the second rotating shaft 403 rotates, the second rotating shaft 403 can drive each turntable 5 to rotate. This enables the second rotating shaft 403 to drive multiple turntables 5 to rotate simultaneously, increasing the width and area of the soil stirred by the stirring mechanism, thereby improving the stirring efficiency of the soil.
[0057] In order to further improve the stirring effect of the stirring mechanism on the soil, in this embodiment, on the second rotating shaft 403, the helix directions of two adjacent worms 405 are opposite, and when the second rotating shaft 403 rotates, the rotation directions of two adjacent turntables 5 are opposite. It can be understood that if the rotation directions of each turntable 5 are the same, the soil will be conveyed along the width direction to one side of the housing 1 by the stirring rod 501 and the crushing rod 502, which will cause the stirring rods 501 on other turntables 5 to need to additionally stir the already stirred soil, resulting in an increase in the rotation resistance of the turntable 5 and a decrease in the stirring efficiency of the soil. Therefore, by setting the helix directions of the two worms 405 to be opposite, the situation where the rotation directions of each turntable 5 are the same is avoided, and the turning efficiency of the stirring mechanism on the soil is improved.
[0058] The soil turning device in this embodiment further includes a driving mechanism for driving the first roller 201, the second roller 301, and the second rotating shaft 403 to rotate, and the driving mechanism is arranged outside one side plate 101.
[0059] The driving mechanism includes a first sprocket 204 and a driving sprocket 205 connected to the first roller 201, a second sprocket 406 and a third sprocket 407 connected to the second shaft 403, and a fourth sprocket 305 connected to the second roller 301. The driving sprocket 205 is connected to the power source of the agricultural machinery through a transmission chain. Two transmission chains 6 are respectively wound between the first sprocket 204 and the second sprocket 406, and between the third sprocket 407 and the fourth sprocket 305. When the power source of the agricultural machinery drives the first roller 201 to rotate through the driving sprocket 205, the first roller 201 can drive the second shaft 403 and the second roller 301 to rotate, thereby facilitating the driving of the soil-breaking roller 2, the soil-turning roller 3 and each rotating disk 5 to rotate.
[0060] Finally, each side panel 101 of this embodiment is provided with a connecting arm 102 for connecting to agricultural machinery. At the same time, the top of the shell 1 of this embodiment can also be provided with a plurality of support frames 103 rotatably connected to the second rotating shaft 403 to support the second rotating shaft 403 and ensure the smooth rotation of the second rotating shaft 403.
[0061] In summary, the soil stirring device of this embodiment, through the arrangement of the soil breaking roller 2, the stirring mechanism and the soil turning roller 3, the rotating soil breaking roller 2 can break up the compacted soil, the turntable 5 and the stirring rod 501 in the stirring mechanism can stir the soil horizontally, and the soil turning roller 3 can turn the soil up and down. Compared with the manual soil turning method, the labor intensity of personnel is reduced, and the soil turning effect and turning efficiency are improved.
[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
