Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to a soil improvement device and method. Background Technology

[0002] Soil improvement is the process of taking appropriate physical, biological, or chemical measures to improve soil properties, increase soil fertility, increase crop yield, and improve the soil environment for human survival, targeting poor soil texture and structure.

[0003] Currently, when people carry out soil improvement operations in farmland, they usually pour soil conditioner into a basin, and then have workers carry the basin around the farmland and spread the conditioner on the soil as they walk. Although this method can achieve the basic purpose of soil improvement, the conditioner can only cover the surface layer of the soil, which greatly reduces the improvement effect on the soil interior. Moreover, most soil in the field is in clumps, which makes it difficult for the soil conditioner to mix with the clumps, thus having an adverse effect on the soil improvement effect.

[0004] Therefore, it is necessary to provide a soil improvement device and method to solve the above problems. Summary of the Invention

[0005] This invention provides a soil improvement device and method, aiming to solve the problems mentioned in the background art, where soil conditioners can only cover the soil surface in current farmland soil improvement operations, thus reducing the soil improvement effect inside, and the clods of soil in the field are difficult to mix with the conditioner, further affecting the overall soil improvement effect.

[0006] To solve the above problems, the present invention is implemented as follows: a soil improvement device, comprising: a box body, wherein the box body has a first cavity and a second cavity, and the bottom inner wall of the second cavity has a discharge port for discharging soil; a U-shaped frame fixedly installed at the bottom of the box body, wherein a first rotating shaft is rotatably installed on the U-shaped frame, a roller is fixedly sleeved on the first rotating shaft, and a plurality of rotary tillage blades for loosening soil in farmland are fixedly installed on the roller; a soil treatment mechanism for crushing soil assembled on the box body; and a feeding mechanism for improving soil installed on the box body.

The second cylinder has an inner wall that is slidably connected to the outer wall of the discharge pipe; a plurality of first soil-breaking cones are fixedly installed on the inner wall of the second cylinder; a first support plate is fixedly installed on the inner wall of the top of the first cavity, and a fourth rotating shaft is rotatably installed on the first support plate, with a third bevel gear and a universal joint fixedly installed at both ends of the fourth rotating shaft; a fifth rotating shaft is rotatably installed on the inner wall of one side of the first cavity, with one end of the fifth rotating shaft fixedly connected to one end of the universal joint; a seventh bevel gear is fixedly sleeved on the second rotating shaft, and the seventh bevel gear meshes with the third bevel gear; a first gear is fixedly sleeved on the fifth rotating shaft; and a second gear is fixedly sleeved on the second cylinder, and the second gear meshes with the first gear.

[0008] Preferably, the feeding mechanism includes: a housing fixedly mounted on the box body, the bottom of the housing having a feeding port that communicates with the interior of the second cavity; a third rotating shaft rotatably mounted on the housing, a material roller fixedly sleeved on the third rotating shaft, the material roller having multiple material troughs; a hopper fixedly mounted on the housing for storing soil conditioner; a disc fixedly mounted on the third rotating shaft, multiple rollers rotatably mounted on the disc; a rotating rod rotatably mounted on the housing, two push rods fixedly mounted on the rotating rod for moving the rollers; a first bevel gear fixedly sleeved on the second rotating shaft; and a second bevel gear fixedly mounted on the rotating rod, the second bevel gear meshing with the first bevel gear.

[0009] Preferably, the soil improvement device further includes a drive mechanism mounted on the housing, the drive mechanism being used to rotate the rotary tiller blades.

[0010] Preferably, the driving mechanism includes: two second support plates fixedly installed on the inner wall of the top of the first cavity, with the same sixth rotating shaft rotatably mounted on the two second support plates, and a fourth bevel gear and a fifth bevel gear fixedly mounted at both ends of the sixth rotating shaft, the fourth bevel gear meshing with the seventh bevel gear; a connecting rod rotatably installed on the inner wall of the first cavity, with the sixth bevel gear fixedly sleeved on the connecting rod, the sixth bevel gear meshing with the fifth bevel gear; and two sprockets fixedly sleeved on the first rotating shaft and the connecting rod, with the same chain sleeved on the two sprockets.

[0011] Preferably, the hopper is hinged with two covers for covering the top of the hopper, and the housing has an installation opening with a door for opening and closing.

[0012] Preferably, the box is equipped with a height adjustment mechanism for raising and lowering the box.

[0013] Preferably, the height adjustment mechanism includes: multiple support blocks fixedly installed on the outer wall of the housing, each of the multiple support blocks having a support rod slidably installed on it, and the top ends of the multiple support rods having the same frame fixedly installed; a hydraulic cylinder fixedly installed on the top of the housing, the output rod of the hydraulic cylinder being fixedly connected to the bottom of the frame; and multiple support frames fixedly installed at the bottom ends of the multiple support rods, each of the multiple support frames being U-shaped, and each of the multiple support frames having a rotatable wheel installed on it.

[0014] Preferably, a mounting bracket is fixedly installed on one side of the housing, and the mounting bracket is used to connect the traction equipment.

[0015] Preferably, the soil improvement method of the soil improvement device includes the following steps: Step 1: Use a mounting frame to install the device onto the traction equipment. After installation, use the traction equipment to move the device to the farmland for use. During the movement, multiple wheels will continuously roll on the ground. Step 2: After the device is moved to the farmland where soil improvement is to be carried out, the hydraulic cylinder is activated to drive the frame to rise. The frame will drive multiple support rods to slide on multiple support blocks, so that multiple support frames move closer to multiple support blocks, thereby allowing the box to descend, so that the rotary tiller blades and guide plates under the box can contact the ground and extend into the soil. Then the hydraulic cylinder is turned off, and the required soil conditioner is poured into the hopper. After it is full, the two covers are flipped over to cover the top of the hopper. Step 3: Then, use a traction device to drag the device, moving it across the farmland. During the movement, the motor must be started simultaneously. The motor will drive the second shaft to rotate, which in turn will drive the seventh bevel gear. The seventh bevel gear will then drive the sixth shaft to rotate on the two second support plates via the fourth bevel gear. The sixth shaft will then drive the fifth bevel gear to rotate, which in turn will drive the connecting rod to rotate inside the first cavity via the sixth bevel gear. The connecting rod will then drive the first shaft to rotate on the U-shaped frame via a chain and two sprockets. The first shaft will then drive the roller to rotate, which in turn will drive multiple rotary tillers to rotate, loosening the soil in the farmland. Step 4: After being loosened, the soil moves towards the first cylinder under the push of the two guide plates, and then enters the first cylinder through the feed inlet. At the same time, the second rotating shaft also drives the spiral blades to rotate, which pushes the soil entering the first cylinder upwards, and then enters the second cylinder through the discharge pipe. At this time, the rotation of the seventh bevel gear will drive the third bevel gear to rotate, which will drive the fourth rotating shaft to rotate on the first support plate. The fourth rotating shaft will drive the fifth rotating shaft to rotate on the inner wall of the first cavity through the universal joint. The fifth rotating shaft will drive the first gear to rotate, which will drive the second gear to rotate, which will drive the second cylinder to rotate. The second cylinder will drive multiple first soil-breaking cones to rotate, so that the soil entering the second cylinder can be crushed by multiple first soil-breaking cones, breaking up the lumpy soil. Then, under the centrifugal force of the second cylinder, the crushed soil can be thrown out from multiple first discharge holes. The thrown soil will be relatively dispersed and will hit the inner wall of the second cavity, so that the thrown soil can be crushed again after being impacted. Step 5: During the soil crushing process, the second rotating shaft simultaneously drives the first bevel gear to rotate. The first bevel gear, through the second bevel gear, drives the rotating rod to rotate. The rotating rod drives the two push rods to rotate, causing the two push rods to continuously push the rollers on the disc, thus intermittently driving the disc to rotate. The disc drives the third rotating shaft to rotate, which in turn drives the material roller to rotate. This causes the multiple material troughs on the material roller to continuously carry the soil conditioner from the hopper downwards. When the material troughs rotate to the bottom, the soil conditioner in the troughs will automatically fall and then be discharged from the feeding port at the bottom of the shell. The discharged soil conditioner will mix with the soil thrown out from the multiple first discharge holes. Under the action of the soil being thrown, the discharged soil conditioner will also be more dispersed, allowing the soil conditioner to mix better with the soil. The soil mixed with the soil conditioner will finally be discharged from the discharge port on the inner wall of the bottom of the second chamber and fall into the farmland, thus achieving soil improvement.

[0016] Compared with related technologies, the soil improvement device and method provided by the present invention have the following beneficial effects: Compared with related technologies, this device achieves soil loosening and crushing in farmland, processing lumpy soil into finer pieces, and fully mixing soil conditioner into the crushed soil. This solves the current problems in farmland soil improvement operations, where soil conditioner can only cover the surface layer of the soil, reducing the soil improvement effect inside, and lumpy soil in the field is difficult to mix with the conditioner, further affecting the overall soil improvement effect.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This invention provides a soil improvement device and method, such as... Figure 1-12 As shown, the soil improvement device includes: a housing 1, on which a first cavity 2 and a second cavity 3 are provided, and the bottom inner wall of the second cavity 3 is provided with a discharge port for discharging soil; a U-shaped frame 4 fixedly installed at the bottom of the housing 1, on which a first rotating shaft 5 is rotatably installed, and a roller 6 is fixedly sleeved on the first rotating shaft 5, and multiple rotary tillage blades 7 for loosening farmland soil are fixedly installed on the roller 6; a soil treatment mechanism for crushing soil assembled on the housing 1; and a feeding mechanism for improving soil installed on the housing 1.

[0021] In this embodiment, when using the device, it must first be connected to a traction device, such as a tractor, to facilitate moving the device in the farmland. During movement, the height of the housing 1 can be adjusted using a height adjustment mechanism, allowing the rotary tillers 7 below the housing 1 to contact the ground and extend into the soil. Once the rotary tillers 7 reach the appropriate position, the soil treatment mechanism is activated. After the soil treatment mechanism is activated, it simultaneously forces the drive mechanism and the feeding mechanism to operate. The drive mechanism drives the first rotating shaft 5 to rotate on the U-shaped frame 4, which in turn drives the roller 6 to rotate. The roller 6 then drives multiple rotary tillers 7 to rotate, thus treating the soil in the farmland. The soil is loosened and then enters the soil treatment unit. There, clumps of soil are crushed and thrown into the second chamber 3. During this process, the feeding mechanism simultaneously delivers a soil conditioner into the second chamber 3. The soil conditioner is in powder form and, due to the impact of the soil's movement, it disperses, allowing for better mixing. The mixed soil is then discharged from the outlet and falls into the farmland, enhancing the soil's internal improvement and providing a more thorough treatment.

[0022] In a further preferred embodiment of the present invention, the soil treatment mechanism includes: a first cylinder 8 fixedly installed on the inner wall of the bottom of the first cavity 2, the bottom end of the first cylinder 8 extending to the outside of the box 1, and a feed inlet on one side of the first cylinder 8; a second rotating shaft 9 rotatably installed on the box 1 and the first cylinder 8, with a spiral blade 10 for conveying soil fixedly sleeved on the second rotating shaft 9; two guide plates 11 fixedly installed on the first cylinder 8; a motor 12 fixedly installed on the top of the box 1, the output shaft of the motor 12 being fixedly connected to the top end of the second rotating shaft 9; a discharge pipe 23 fixedly installed on the first cylinder 8; and a second cylinder 24 rotatably installed on the inner wall of one side of the second cavity 3, the second cylinder 24 having a plurality of first discharge holes, one end of the second cylinder 24 extending into the interior of the first cavity 2. The inner wall of the second cylinder 24 is slidably connected to the outer wall of the discharge pipe 23; a plurality of first soil-breaking cones 32 are fixedly installed on the inner wall of the second cylinder 24; a first support plate 25 is fixedly installed on the inner wall of the top of the first cavity 2, and a fourth rotating shaft 26 is rotatably installed on the first support plate 25, with a third bevel gear 31 and a universal joint 27 fixedly installed at both ends of the fourth rotating shaft 26 respectively; a fifth rotating shaft 28 is rotatably installed on the inner wall of one side of the first cavity 2, with one end of the fifth rotating shaft 28 fixedly connected to one end of the universal joint 27; a seventh bevel gear 43 is fixedly sleeved on the second rotating shaft 9, and the seventh bevel gear 43 meshes with the third bevel gear 31; a first gear 29 is fixedly sleeved on the fifth rotating shaft 28; a second gear 30 is fixedly sleeved on the second cylinder 24, and the second gear 30 meshes with the first gear 29.

[0023] In this embodiment, the soil treatment mechanism is used to crush soil. During use, the loosened soil moves towards the first cylinder 8 under the push of two guide plates 11, and then enters the first cylinder 8 through the feed inlet. At this time, the motor 12 is started, which drives the second rotating shaft 9 to rotate. The second rotating shaft 9 simultaneously drives the spiral blades 10 to rotate, and the spiral blades 10 push the soil entering the first cylinder 8 upwards, then into the second cylinder 24 through the discharge pipe 23. At this time, the seventh bevel gear 43, fixedly sleeved on the second rotating shaft 9, simultaneously drives the third bevel gear 31 to rotate. The third bevel gear 31 drives the fourth rotating shaft 26 to rotate on the first support plate 25. The fourth rotating shaft 26 drives the fifth rotating shaft 28 to rotate on the inner wall of the first cavity 2 via the universal joint 27. The fifth rotating shaft 28 drives the first gear 29 to rotate, the first gear 29 drives the second gear 30 to rotate, the second gear 30 drives the second cylinder 24 to rotate, and the second cylinder 24 drives multiple first soil-breaking cones 32 to rotate, so that the soil entering the second cylinder 24 can be crushed by the multiple first soil-breaking cones 32, breaking up the lumpy soil. Then, under the centrifugal force of the second cylinder 24, the crushed soil can be thrown out from multiple first discharge holes. The thrown soil will be relatively dispersed and will hit the inner wall of the second cavity 3, so that the thrown soil can be crushed again after being impacted.

[0024] In a further preferred embodiment of the present invention, the feeding mechanism includes: a housing 13 fixedly mounted on the box 1, the bottom of the housing 13 having a feeding port that communicates with the interior of the second cavity 3; a third rotating shaft 14 rotatably mounted on the housing 13, a material roller 15 fixedly sleeved on the third rotating shaft 14, the material roller 15 having multiple material troughs; a hopper 16 fixedly mounted on the housing 13 for storing soil conditioner; a disc 17 fixedly mounted on the third rotating shaft 14, a plurality of rollers 18 rotatably mounted on the disc 17; a rotating rod 19 rotatably mounted on the housing 13, two push rods 20 fixedly mounted on the rotating rod 19 for moving the rollers 18; a first bevel gear 21 fixedly sleeved on the second rotating shaft 9; and a second bevel gear 22 fixedly mounted on the rotating rod 19, the second bevel gear 22 meshing with the first bevel gear 21.

[0025] In this embodiment, the feeding mechanism is used to improve the soil. During the soil crushing process, the second rotating shaft 9 simultaneously drives the first bevel gear 21 to rotate. The first bevel gear 21 drives the rotating rod 19 to rotate via the second bevel gear 22. The rotating rod 19 drives the two push rods 20 to rotate, causing the two push rods 20 to continuously push the rollers 18 on the disc 17, thereby intermittently driving the disc 17 to rotate. The disc 17 drives the third rotating shaft 14 to rotate, and the third rotating shaft 14 drives the material roller 15 to rotate, causing multiple rollers on the material roller 15 to rotate. The trough continuously carries the soil conditioner in the hopper 16 downwards. When the trough rotates to the bottom, the soil conditioner in the trough will automatically fall and then be discharged from the feeding port at the bottom of the shell 13, realizing intermittent discharge. The discharged soil conditioner is in powder form. The discharged soil conditioner will mix with the soil thrown out from multiple first discharge holes. Under the action of soil swaying, the discharged soil conditioner will also be more dispersed, so that the soil conditioner can be better mixed with the soil, which can improve the improvement effect on the soil interior and make the improvement more thorough.

[0026] In a further preferred embodiment of the present invention, the soil improvement device further includes a drive mechanism installed on the housing 1, the drive mechanism being used to rotate the rotary tiller blades 7.

[0029] In this embodiment, when the motor 12 drives the second rotating shaft 9 to rotate, the seventh bevel gear 43, which is fixedly sleeved on the second rotating shaft 9, will drive the fourth bevel gear 35 to rotate, which in turn will drive the sixth rotating shaft 34 to rotate on the two second support plates 33. The sixth rotating shaft 34 will drive the fifth bevel gear 36 to rotate. The fifth bevel gear 36 will drive the connecting rod 37 to rotate through the sixth bevel gear 38. The connecting rod 37 will drive the first rotating shaft 5 to rotate on the U-shaped frame 4 through the chain 40 and two sprockets 39. The first rotating shaft 5 will drive the roller 6 to rotate. The roller 6 will drive multiple rotary tillers 7 to rotate, thereby loosening the soil in the farmland.

[0032] In a further preferred embodiment of the present invention, a height adjustment mechanism is installed on the box 1, and the height adjustment mechanism is used to raise and lower the box 1.

[0033] In this embodiment, the height of the rotary tiller 7 and the guide plate 11 can be adjusted by using a height adjustment mechanism to improve soil at different depths.

[0034] In a further preferred embodiment of the present invention, the height adjustment mechanism includes: a plurality of support blocks 64 fixedly installed on the outer wall of the housing 1, each of the plurality of support blocks 64 having a support rod 65 slidably installed on it, and the top ends of the plurality of support rods 65 having the same frame 66 fixedly installed on them; a hydraulic cylinder 67 fixedly installed on the top of the housing 1, the output rod of the hydraulic cylinder 67 being fixedly connected to the bottom of the frame 66; and a plurality of support frames 68 respectively fixedly installed on the bottom ends of the plurality of support rods 65, each of the plurality of support frames 68 being U-shaped, and each of the plurality of support frames 68 having a rotatable wheel 62 mounted on it.

[0035] In this embodiment, when the height adjustment mechanism is in use, the hydraulic cylinder 67 is activated to drive the frame 66 to move vertically. The frame 66 will drive multiple support rods 65 to slide on multiple support blocks 64, so that multiple support frames 68 move closer to multiple support blocks 64 respectively, thereby realizing the lifting and lowering of the box 1, so that the working height of the rotary tiller 7 and the guide plate 11 under the box 1 can be adjusted.

[0039] In this embodiment, when the soil moisture is too low or too high, the operator can adjust the exposure size of multiple first discharge holes according to the soil moisture. During adjustment, first loosen two bolts 57. The two bolts 57 will move on the two covers 56 respectively and drive the two fixed cones 58 to disengage from the inserted conical grooves 59. After disengagement, the position of the sleeve 54 on the second cylinder 24 can be adjusted. When moving the sleeve 54, the sleeve 54 will slide on the rectangular rod 55 at the same time, so that the second discharge hole on the second cylinder 24 and the first discharge hole on the second cylinder 24 are intersected, thereby reducing or increasing the exposure size of the first discharge hole. After adjustment, tighten the two bolts 57 so that the fixed cones 58 on the two bolts 57 are inserted into the corresponding conical grooves 59, thereby fixing the sleeve 54.

At this time, the fourth gear 53, fixed to the rotating rod 19, drives the third gear 52 to rotate. The third gear 52 drives the seventh rotating shaft 50 to rotate on the positioning plate 49. The seventh rotating shaft 50 drives the cam 51 to rotate. The cam 51 continuously presses against the push plate 48. The push plate 48 drives the moving rod 47 to slide on the housing 1 and press against the screen 45, causing the screen 45 to move downward. The screen 45 drives the sliding block 44 to slide on the sliding rod 41 and compress the spring 42. When the protruding part of the cam 51 moves away from the push plate 48, the screen 45 moves downward. When the plate 48 is in motion, the spring 42 will push the sliding block 44 upward through its elasticity. The sliding block 44 will push the screen 45, the moving rod 47, and the push plate 48 upward. In this way, under the reciprocating rotation of the cam 51, the screen 45 can sieve the soil mixed with the soil conditioner, so that the soil conditioner can be mixed with the soil again. At the same time, the soil can pass through the mesh of the screen 45 and then be discharged from the discharge port on the bottom inner wall of the second cavity 3 and fall into the farmland. In this process, some soil that is not fully crushed can also be crushed again by the second soil-breaking cone 46 on the screen 45, which can further improve the soil improvement effect.

[0044] In another embodiment of the present invention, a baffle 61 for shielding the groove is fixedly sleeved on each of the plurality of sliding blocks 44, and the edges of the plurality of baffles 61 are fixedly connected to the inner wall of the second cavity 3.

[0045] In this embodiment, the use of the baffle 61 can prevent soil from entering the trough, thus preventing the spring 42 from being disturbed by the soil.

[0046] The present invention also provides a soil improvement method for a soil improvement device, comprising the following steps: Step 1: Use the mounting bracket 63 to install the device onto the traction equipment. After installation, use the traction equipment to move the device to the farmland for use. During the movement, multiple wheels 62 will continuously roll on the ground. Step 2: After the device is moved to the farmland where soil improvement is to be carried out, the hydraulic cylinder 67 is activated to drive the frame 66 to rise. The frame 66 will drive multiple support rods 65 to slide on multiple support blocks 64, so that multiple support frames 68 move closer to multiple support blocks 64 respectively, thereby allowing the box 1 to descend, so that the rotary tiller 7 and the guide plate 11 under the box 1 contact the ground and extend into the soil. Then the hydraulic cylinder 67 is turned off, and the required soil conditioner is poured into the hopper 16. After it is full, the two covers are flipped over so that the two covers cover the top of the hopper 16. Step 3: Then, the device is dragged using a traction device to move it in the farmland. During the movement, the motor 12 needs to be started at the same time. The motor 12 will drive the second rotating shaft 9 to rotate, the second rotating shaft 9 will drive the seventh bevel gear 43 to rotate, the seventh bevel gear 43 will drive the sixth rotating shaft 34 to rotate on the two second support plates 33 through the fourth bevel gear 35, the sixth rotating shaft 34 will drive the fifth bevel gear 36 to rotate, the fifth bevel gear 36 will drive the connecting rod 37 to rotate inside the first cavity 2 through the sixth bevel gear 38, the connecting rod 37 will drive the first rotating shaft 5 to rotate on the U-shaped frame 4 through the chain 40 and two sprockets 39, the first rotating shaft 5 will drive the roller 6 to rotate, and the roller 6 will drive multiple rotary tillers 7 to rotate, loosening the soil in the farmland. Step 4: After being loosened, the soil moves towards the first cylinder 8 under the push of the two guide plates 11, and then enters the first cylinder 8 through the inlet. At the same time, the second rotating shaft 9 also drives the spiral blades 10 to rotate. The spiral blades 10 push the soil entering the first cylinder 8 upwards, and then enter the second cylinder 24 through the discharge pipe 23. At this time, the rotation of the seventh bevel gear 43 will simultaneously drive the third bevel gear 31 to rotate. The third bevel gear 31 will drive the fourth rotating shaft 26 to rotate on the first support plate 25. The fourth rotating shaft 26 will drive the fifth rotating shaft 28 through the universal joint 27. The inner wall of cavity 2 rotates, the fifth rotating shaft 28 drives the first gear 29 to rotate, the first gear 29 drives the second gear 30 to rotate, the second gear 30 drives the second cylinder 24 to rotate, and the second cylinder 24 drives multiple first soil-breaking cones 32 to rotate, so that the soil entering the second cylinder 24 can be crushed by multiple first soil-breaking cones 32, breaking the lumpy soil. Then, under the centrifugal action of the second cylinder 24, the crushed soil can be thrown out from multiple first discharge holes. The thrown soil will be relatively dispersed and will hit the inner wall of the second cavity 3, so that the thrown soil can be crushed again after being impacted. Step 5: During the soil crushing process, the second rotating shaft 9 simultaneously drives the first bevel gear 21 to rotate. The first bevel gear 21, through the second bevel gear 22, drives the rotating rod 19 to rotate. The rotating rod 19 drives the two push rods 20 to rotate, causing the two push rods 20 to continuously push the rollers 18 on the disc 17, thus intermittently driving the disc 17 to rotate. The disc 17 then drives the third rotating shaft 14 to rotate, which in turn drives the material roller 15 to rotate, allowing the multiple material troughs on the material roller 15 to continuously carry the hopper. The soil conditioner in 16 moves downwards. When the trough rotates to the bottom, the soil conditioner in the trough will automatically fall and then be discharged from the feeding port at the bottom of the shell 13. The discharged soil conditioner will mix with the soil thrown out from multiple first discharge holes. Under the action of the soil being thrown, the discharged soil conditioner will also be more dispersed, so that the soil conditioner can be better mixed with the soil. The soil mixed with the soil conditioner will finally be discharged from the discharge port on the bottom inner wall of the second chamber 3 and fall into the farmland to achieve soil improvement.

[0047] In summary, compared with related technologies, this device achieves soil loosening and pulverization in farmland, processing lumpy soil into finer pieces, and fully mixing soil conditioner into the pulverized soil. This solves the current problems in farmland soil improvement operations, where soil conditioner can only cover the surface layer of the soil, reducing the internal soil improvement effect, and lumpy soil in the field is difficult to mix with the conditioner, further affecting the overall soil improvement effect.

Step four: the loosened soil is pushed by the two guide plates to the position of the first cylinder, and then enters the first cylinder from the feed port. At this time, the second rotating shaft also rotates the spiral blade, which pushes the soil in the first cylinder upwards and then enters the second cylinder from the discharge pipe. At this time, under the rotation of the seventh bevel gear, the third bevel gear is also rotated, which drives the fourth rotating shaft to rotate on the first support plate.

When the material groove rotates to the lower side, the soil conditioner in the material groove falls automatically, and then is discharged from the feeding port at the bottom of the shell. The discharged soil conditioner is mixed with the soil thrown out of the multiple first discharge holes. Under the action of soil throwing, the discharged soil conditioner is also hit and dispersed, so that the soil conditioner can be better mixed with the soil. The soil mixed with the soil conditioner is finally discharged from the discharge port at the bottom of the second cavity, and then falls into the farmland, realizing the improvement of the soil.
