[0002] In agricultural production, soil turning is necessary to loosen the soil and make it easier to plant crops. However, in some mountainous or hilly areas, the soil often contains stones, which can affect crop growth.

[0003] Patent CN222967379U discloses a soil-turning device for agricultural machinery, relating to the field of soil-turning devices for agricultural machinery. It includes multiple blades, a support shaft mounted on the outer periphery of the turning shaft, a mudguard mounted on the outer periphery of the support shaft, and a crushing unit and a transmission unit located below the mudguard. This soil-turning device collects soil clods through a collection frame, with an outlet at the bottom end of the collection frame. Smaller clods fall through the outlet, and a drive mechanism rotates the main bevel gear, which in turn rotates the driven bevel gear, which in turn rotates the transmission shaft, driving the crushing roller to crush the larger clods. While this patent solves the problem of crushing soil clods of varying sizes, the presence of stones in the soil can damage the crushing roller, causing damage to the machinery and preventing the removal of small stones, thus affecting subsequent planting.

[0015] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] like Figures 1 to 7 As shown, an agricultural machinery soil-turning device can turn over the soil and screen out stones from it. It includes a soil-turning mechanism 1, a vibration mechanism 3, a screening mechanism 5, and a mudguard 2, as shown. Figure 1As shown, a frame 207 is fixedly connected to one side of the mudguard 2. The frame 207 extends through both the upper and lower ends of the mudguard 2. A splined shaft 206 is rotatably connected to the upper end of the frame 207, which is perpendicular to the length of the mudguard 2. The splined shaft 206 connects to a universal joint, which in turn connects to the tractor for transmission. A helical gear 209 is fixedly connected to one end of the splined shaft 206 inside the frame 207. A shaft 205 is rotatably connected to the upper end of the frame 207, which is parallel to the length of the mudguard 2. A helical gear 208 is fixedly connected in the middle of the shaft 205. A sprocket 2051 is fixedly connected to the shaft 205 on one side of the helical gear 208. The helical gear 208 and the helical gear 209 mesh and transmit power. The helical gear 209 drives the helical gear 208, which in turn drives the shaft 205 to rotate. The shaft 205 then drives the entire utility model to rotate. A shaft 205 passes through the frame 207 and is fixedly connected to two ends of a sprocket 204. A chain 203 is meshed and driven on the sprocket 204. A support frame 201 is fixedly connected to a mudguard 2 on one side of the frame 207. A frame shaft 212 is rotatably connected to the middle of the support frame 201. A half-gear 213 is fixedly connected to the middle of the frame shaft 212. Sprockets 202 are fixedly connected to the frame shafts 212 on both sides of the half-gear 213. Sprockets 202 and chain 203 are meshed and driven. The half-gear 213 is connected to the vibration mechanism 3. One half of the half-gear 213 has a gear, and the other half does not.

[0017] like Figure 5 As shown, the oscillation mechanism 3 includes an oscillation plate 306, which has a strip-shaped hollow design. A fixing frame 305 is fixedly connected to the upper middle of the oscillation plate 306. Two limiting posts 304 are fixedly connected above the fixing frame 305. The limiting posts 304 pass through the mudguard 2 and are slidably connected to the mudguard 2. A horizontal plate 301 is fixedly connected to the upper end of the two limiting posts 304. A toothed plate 302 is fixedly connected to one side of the middle of the horizontal plate 301. The toothed plate 302 meshes with a half-gear 213 for transmission. The limiting posts 304... 4. A spring 303 is nested on the outside. One end of the spring 303 abuts against the horizontal plate 301, and the other end of the spring 303 abuts against the mudguard 2. The advantage of this design is that when the toothed plate 302 meshes with the half gear 213, it can drive the vibrating plate 306 to move downward, and the spring 303 is squeezed to crush the soil. When the toothed plate 302 does not mesh with the half gear 213, the spring 303 stretches and moves the vibrating plate 306 upward. This process is repeated to crush the soil through the vibrating plate 306.

[0018] A screen plate 8, fixedly connected to the mudguard 2, is located directly below the vibrating plate 306. A screening mechanism 5 is installed directly below the screen plate 8, such as... Figure 5As shown, the screening mechanism 5 includes a base frame 502, on which multiple prisms 503 are fixedly connected. The function of the prisms 503 is to cut the soil clods falling from the screen plate 8 using the ridges of the prisms 503. Limiting plates 501 are fixedly connected to the upper two sides of the base frame 502 in the width direction. The upper ends of the limiting plates 501 abut against the bottom of the mudguard plate 2. Flat plates 504 are fixedly connected to the two sides of the base frame 502 in the length direction. A baffle 506 is fixedly connected to one end of the flat plate 504. A cylinder 505 is fixedly connected to one end of the baffle 506. Flat grooves 214 are opened at the bottom of both sides of the mudguard plate 2. The flat plates 504 and the flat grooves 214 are slidably connected. The flat grooves 214 limit the base frame 502, allowing only the base frame 502 to move back and forth.

[0019] The bottom of the frame 207 is rotatably connected to the soil-turning mechanism 1. The soil-turning mechanism 1 includes a shaft 101, which is rotatably connected to the frame 207. A sprocket 1011 is fixedly connected to the part of the shaft 101 inside the frame 207. A chain 105 is meshed and driven on the sprocket 1011. The chain 105 is meshed and driven on the sprocket 2051. Multiple sets of blades 102 are fixedly connected to the shaft 101. Circular plates 103 are fixedly connected to both ends of the shaft 101 through the mudguard 2. A cylinder 104 is fixedly connected to the circular plate 103 at a point not at its center. A guide rod 6 is rotatably connected to the cylinder 104. A cylinder 205 is rotatably connected to one end of the guide rod 6. The eccentric rotation of the cylinder 104 drives the reciprocating movement of the base frame 502.

[0020] Inside the mudguard 2, an arc plate 211 is fixedly connected between the soil-turning mechanism 1 and the vibration mechanism 3. The function of the arc plate 211 is to reduce the amount of soil that falls onto the vibration plate 306 when the blade 102 turns the soil onto the screen plate 8. Even if some soil falls onto the vibration plate 306, it can fall down through the perforations on the vibration plate 306. The mudguard 2 is rotatably connected to a tail plate 4 at one end of the vibration mechanism 3. When unbroken, harder clods of soil or stones remain on the mudguard 2 on one side of the screen plate 8, after the soil turning is completed, simply open the tail plate 4 to remove the unbroken, harder clods of soil or stones inside.

[0021] A top cover 7 is fixedly connected above the mudguard 2. The top cover 7 covers the upper part of the support frame 201, the frame box 207, and the upper part of the vibration mechanism 3. The reason for setting the top cover 7 is that, since this utility model is for turning over soil, it needs to be in contact with soil dust for a long time. Therefore, the top cover 7 can isolate the dust from the outside and prevent the dust from affecting the meshing and transmission of the internal parts. Those skilled in the art can use existing technologies, such as installing corresponding mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator in the following operation process. To achieve automated operation, this utility model can use CNC technology or PLC to control the operation of each actuator.

[0022] Working process: This utility model is connected to the tractor via a splined shaft 206. The tractor frame drives the splined shaft 206 to rotate, and the helical gear 209 behind the splined shaft 206 drives the helical gear 208 and sprocket 2051, which are fixed on the shaft 205, to rotate. The chain 105 connected to sprocket 2051 drives sprocket 1011 to rotate, and the shaft 101, which is fixedly connected to sprocket 1011, rotates, driving the cutter 102 on the shaft 101 to rotate. As the tractor moves forward, the rotating cutter 102 turns over the soil.

[0023] As the shaft 101 rotates, the cylinders 104 on both sides of the shaft 101 rotate, driving the guide rod 6 to move. The guide rod 6 drives the screening mechanism 5 to move back and forth, cutting the large clods of soil that fall on the screen plate 8, while some stones or harder clods are moved to the rear through the screen plate 8. As shaft 205 rotates, sprockets 204 connected to both ends of shaft 205 rotate, driving chain 203 to rotate. Chain 203 drives sprocket 202 to rotate, and the frame shaft 212, which is fixedly connected to sprocket 202, rotates, causing the half-gear 213 in the middle of the frame shaft 212 to rotate. When the toothed end of the half-gear 213 meshes with the toothed plate 302, it drives the vibrating plate 306 to move downward, squeezing and crushing large clods of soil that fall onto the screen plate 8. When the half-gear 213 rotates to the toothless side and can no longer mesh with the toothed plate 302, the vibrating plate 306 is subjected to the elastic force of spring 303 and contracts upward. The intermittent meshing of the half-gear 213 and the toothed plate 302 causes the vibrating plate 306 to move up and down reciprocally, crushing the soil clods.

[0024] After the entire plot of land has been tilled, open the tail plate 4 and remove any stones or hard clods of soil left inside the device.

[0025] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
