Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and more specifically, to a soil improvement and tillage device based on ecological farmland. Background Technology

[0002] Soil improvement is an important measure to eliminate soil obstacles, improve soil physicochemical properties, enhance soil fertility, and create a favorable soil environment for plant growth and the rational use of land resources. The basic types of soil improvement include five categories: soil erosion improvement, salinization and secondary salinization soil improvement, sandy soil improvement, marshland soil improvement, and red and yellow soil improvement.

[0003] Existing soil improvement and tillage devices generally only have the function of breaking and tilling soil, but do not have the function of filtering. This means that if the tilled soil contains weed roots or non-biodegradable waste, it cannot effectively separate them from the soil. Furthermore, after the tillage device is connected to the power machinery, its tillage depth cannot be adjusted, resulting in a limited range of applications for the device.

[0004] Therefore, it is necessary to design a soil improvement and tillage device based on ecological farmland to solve the above problems. Summary of the Invention

[0005] In view of this, the present invention proposes a soil improvement and tillage device based on ecological farmland to solve the problems existing in the prior art.

The fixed walking part is fixedly connected to the rear end of the bottom of the fixed frame.

[0010] In one embodiment, the movable walking part includes two third telescopic rods, which are respectively fixedly connected to the bottom sides of the fixed frame. The third telescopic rods are vertically arranged, and the telescopic ends of the third telescopic rods are rotatably connected to walking wheels. The fixed walking part includes two connecting rods, which are respectively fixedly connected to the bottom sides of the fixed frame.

[0011] In one embodiment, the height adjustment mechanism includes a connecting frame, which is Y-shaped. Both ends of the connecting frame are fixedly connected to the front end of the fixed frame. A hinge seat is fixedly connected to the top of the third end of the connecting frame. The hinge seat is rotatably connected to the telescopic end of a first telescopic rod. A hanging ring is rotatably connected to the fixed end of the first telescopic rod.

[0012] In one embodiment, the soil-breaking mechanism includes two support rods, which are respectively fixedly connected to both sides of the bottom end of the fixed frame. The bottom ends of the two support rods are rotatably connected to a breaking roller, which is located in front of the free end of the shovel plate. A driven sprocket is fixedly sleeved on one end of the breaking roller. A plurality of breaking blades are fixedly connected to the outer wall of the breaking roller. The plurality of breaking blades are equally spaced along the circumference and axial direction of the outer wall of the breaking roller. A drive motor is fixedly connected to the fixed frame. A drive sprocket is fixedly connected to the output end of the drive motor. The drive sprocket is connected to the driven sprocket through a transmission chain.

[0013] In one embodiment, the screening mechanism includes a screening trough, which is inclined and its high end is located below the high end of the guide trough. The screening trough has several through holes. Sliding rods are slidably inserted through the high end and the low end of the screening trough, respectively. Both ends of the sliding rods are fixedly connected to the bottom end of the fixed frame through fixed plates.

During the operation of the screening mechanism, weed roots and other non-degradable waste mixed in with the crushed soil are separated. The soil without waste after separation falls back to the ground, while the filtered waste is collected and processed. After the conveying mechanism scoops up the crushed soil, the first spraying mechanism sprays soil amendment liquid onto the surface of the uncrushed land. After the filtered soil falls back, it covers the surface of the soil amendment liquid, prolonging the effect time of the soil amendment liquid in the soil. At the same time, the second spraying mechanism also sprays soil amendment liquid on the surface of the crushed soil that has fallen back to the ground. The dual spraying method of soil amendment liquid can maximize the improvement effect. The height adjustment mechanism can connect the fixing frame to the power machinery and adjust the height of the soil crushing mechanism according to the depth of the soil to be tilled, thereby improving the applicability of the device.

Detailed Implementation

[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] This embodiment proposes a soil improvement and tillage device based on ecological farmland, such as... Figures 1 to 3 As shown, it includes: a fixed frame 1, with a height adjustment mechanism fixedly connected to its front end, and the fixed frame 1 is detachably connected to a power device through the height adjustment mechanism; a walking mechanism, fixedly connected to the bottom of the fixed frame 1; a soil crushing mechanism, fixed inside the front end of the fixed frame 1, used to crush the soil; a conveying mechanism, fixed inside the fixed frame 1, located behind the soil crushing mechanism, used to convey the crushed soil; a screening mechanism, fixed inside the fixed frame 1, located behind the conveying mechanism, used to screen the crushed soil; a first spraying mechanism, fixed at the top center of the fixed frame 1, with the liquid outlet of the first spraying mechanism located below the conveying mechanism; and a second spraying mechanism, fixed at the top rear end of the fixed frame 1, with the liquid outlet of the second spraying mechanism located at the rear end of the fixed frame 1.

[0021] The scheme is further optimized. The conveying mechanism includes a guide trough 14, which is fixedly connected inside the fixed frame 1. The guide trough 14 is inclined. The lower end of the guide trough 14 is close to the soil crushing mechanism and is rotatably connected to the soil shovel. The upper end of the guide trough 14 is located above the feed end of the screening mechanism.

[0022] The design is further optimized so that the shovel unit includes two fourth telescopic rods 28, which are fixedly connected to both sides of the bottom of the fixed frame 1. The fourth telescopic rods 28 are vertically arranged, and the telescopic ends of the fourth telescopic rods 28 are provided with elongated through holes 29. A connecting shaft 27 is movably arranged in the elongated through hole 29. The two connecting shafts 27 are fixedly connected to a shovel plate 26. Several connecting lugs 30 are fixedly connected to the long side of the shovel plate 26. Several connecting grooves 31 are provided on the low side of the guide channel 14. The connecting lugs 30 correspond one-to-one with the connecting grooves 31 and are rotatably arranged in the connecting grooves 31.

[0023] As the power machinery moves forward, the soil-crushing mechanism breaks up the soil that needs to be tilled. The broken soil is then scooped up by the shovel plate 26 and transported to the guide trough 14. The power for transporting the broken soil comes from the continuous forward movement of the power machinery and the squeezing force of the broken soil that has not been scooped up. The power machinery can be a tractor or an agricultural tricycle. The guide trough 14 transports the broken soil to the screening mechanism for screening.

[0024] The height of the free end of the shovel plate 26 when it is in its lowest position is higher than the height of the soil crushing mechanism when it is in its lowest position. This ensures that the shovel plate 26 can scoop up the crushed soil without interfering with the uncrushed soil. The height of the free end of the shovel plate 26 can be adjusted by extending and retracting the fourth telescopic rod 28. This allows the device to scoop up soil of different thicknesses. For example, if the soil crushing mechanism crushes soil to a depth of 20cm, the shovel plate 26 can scoop up soil with a thickness of 18cm or 10cm after adjusting the shovel plate 26 with the fourth telescopic rod 28. This improves the applicability of the device.

[0025] The design is further optimized so that the walking mechanism includes a fixed walking part and two movable walking parts. One movable walking part is fixedly connected to the bottom front end of the fixed frame 1, the other movable walking part is fixedly connected to the bottom middle of the fixed frame 1, and the fixed walking part is fixedly connected to the bottom rear end of the fixed frame 1.

[0026] The design is further optimized so that the mobile walking unit includes two third telescopic rods 7, which are fixedly connected to the bottom sides of the fixed frame 1 respectively. The third telescopic rods 7 are set vertically, and the telescopic ends of the third telescopic rods 7 are rotatably connected to walking wheels 9.

[0027] The fixed walking part includes two connecting rods 8, which are fixedly connected to the bottom sides of the fixed frame 1 respectively. The connecting rods 8 are vertically arranged, and the bottom ends of the connecting rods 8 are rotatably connected to the walking wheels 9.

[0028] After the fixed frame 1 is connected to the power machinery through the height adjustment mechanism, the height of the front end of the fixed frame 1 can be adjusted according to the actual soil depth to be broken, thereby changing the breaking depth of the soil breaking mechanism. When the height of the front end of the fixed frame 1 changes, the third telescopic rod 7 set at the bottom front end and middle of the fixed frame 1 can extend and retract by different lengths to ensure that the traveling wheels 9 at the bottom front end and middle of the fixed frame 1 are always in contact with the ground, reducing power loss and ensuring stable forward movement of the device.

[0029] Further optimization of the scheme: the height adjustment mechanism includes a connecting frame 2, which is Y-shaped. Both ends of the connecting frame 2 are fixedly connected to the front end of the fixed frame 1. The top of the third end of the connecting frame 2 is fixedly connected to a hinge seat 3. The hinge seat 3 is rotatably connected to the telescopic end of the first telescopic rod 4. The fixed end of the first telescopic rod 4 is rotatably connected to a hanging ring 5.

[0030] The entire device is connected to the power machinery by the hanging ring 5, and the first telescopic rod 4 is extended or shortened to adjust the crushing depth of the soil crushing mechanism.

[0031] Further optimization of the scheme: the soil crushing mechanism includes two support rods 25, which are fixedly connected to the bottom sides of the fixed frame 1 respectively. The bottom ends of the two support rods 25 are rotatably connected to a crushing roller 23. The crushing roller 23 is located in front of the free end of the shovel plate 26. A driven sprocket 22 is fixedly sleeved on one end of the crushing roller 23. Several crushing blades 24 are fixedly connected to the outer wall of the crushing roller 23. The several crushing blades 24 are evenly spaced along the circumference and axial direction of the outer wall of the crushing roller 23. A drive motor 19 is fixedly connected to the fixed frame 1. A drive sprocket 20 is fixedly connected to the output end of the drive motor 19. The drive sprocket 20 is connected to the driven sprocket 22 through a transmission chain 21.

[0032] The drive motor 19 drives the crushing roller 23 and the crushing blade 24 to rotate at high speed through the transmission chain 21, thereby crushing the soil.

[0033] Further optimization of the scheme: the screening mechanism includes a screening trough 15, which is inclined and its high end is located below the high end of the guide trough 14. Several through holes are opened on the screening trough 15. Slide rods 33 are slidably passed through the high end and the low end of the screening trough 15, respectively. Both ends of the slide rods 33 are fixedly connected to the bottom end of the fixed frame 1 through fixed plates 32. A vibration motor 34 is fixedly connected to the side wall of one of the fixed plates 32 near the high end of the screening trough 15. The output end of the vibration motor 34 is fixedly connected to the screening trough 15. A garbage trough 35 is provided behind the low end of the screening trough 15. The top end of the garbage trough 35 is fixedly connected to the bottom end of the fixed frame 1, and the side wall near the screening trough 15 is set as an opening. An extension plate 36 is fixedly connected to the side wall of the opening. The extension plate 36 is located below the low end of the screening trough 15.

[0034] After the crushed soil falls onto the screening tank 15 through the guide channel 14, the vibrating motor 34 drives the screening tank 15 to vibrate repeatedly at high speed. During the vibration, the soil falls back to the ground through the through hole, while the garbage is filtered and remains on the screening tank 15. At the same time, due to the inclined setting of the screening tank 15, the filtered garbage rolls into the garbage trough 35 and is collected during the continuous vibration of the screening tank 15.

[0035] Further optimization of the scheme: the first spraying mechanism includes a first liquid tank 10, which is fixedly connected to the top center of the fixed frame 1. The first liquid tank 10 is fixedly connected to a connecting pipe 11, which is U-shaped. The horizontal section of the connecting pipe 11 is located below the center of the guide channel 14. The horizontal section of the connecting pipe 11 is fixedly connected to a number of first nozzles 12, which are arranged at equal intervals.

[0036] The first liquid tank 10 is equipped with two water pumps. The outlets of the two water pumps are connected to the two ends of the connecting pipe 11 respectively. The water pumps pump the improvement liquid into the connecting pipe 11 and finally spray it onto the unbroken ground through the first nozzle 12. After the sieving tank 15 sieves the soil, the soil without garbage falls back onto the ground and covers the improvement liquid, thus prolonging the effect time of the improvement liquid.

[0037] The scheme is further optimized. The second spraying mechanism includes a second liquid tank 13, which is fixedly connected to the top rear end of the fixed frame 1. One end of the second liquid tank 13 is fixedly connected to a bend 16, and the other end of the bend 16 is fixedly connected to an outlet pipe 17. The outlet pipe 17 is located behind the fixed frame 1, and a number of second nozzles 18 are fixedly connected to the outlet pipe 17. The number of second nozzles 18 are equally spaced.

[0038] The second liquid tank 13 is also equipped with a water pump. The outlet of the water pump is connected to the bend pipe 16. After the filtered soil without garbage falls back to the ground, the water pump pumps the improvement liquid into the outlet pipe 17. The improvement liquid is sprayed onto the surface of the broken soil through the second nozzle 18, which, together with the improvement liquid inside the soil, enhances the soil improvement effect.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention.
