Description

Technical Field

[0001] The present invention relates to the technical field of agricultural soil treatment, and particularly relates to an agricultural soil improvement operation device. Background Art

[0002] Soil improvement refers to using the theories and technologies of multiple disciplines such as soil science, biology, and ecology to eliminate or prevent adverse factors that affect crop growth and cause soil degradation. For example, spraying relevant liquid medicines on the soil to improve soil fertility and create good soil environmental conditions for crops.

[0003] A Chinese patent with the authorization announcement number CN117837322B discloses an agricultural equipment for improving soil in agriculture, including a carrier frame. A driving motor is installed on the surface of the carrier frame, a feeding cylinder is fixedly installed on the inner wall of the carrier frame, a conveying shaft is rotatably connected at the axial position of the feeding cylinder, a discharging mechanism cooperating with the conveying shaft is installed at the tail of the feeding cylinder, and a soil-return spraying component cooperating with the discharging mechanism is installed on the top surface of the carrier frame. In this solution, the crushed soil is discharged through the discharging mechanism and conveyed to the soil-return spraying component, and then the swing pipe in the soil-return spraying component swings back and forth to scatter the soil over a large area, facilitating the uniform fall of the soil back to the ground, and spraying liquid medicine by relying on the medicine spraying component during the process of scattering the soil.

[0004] The deficiencies of the above-mentioned prior art solutions are as follows: Although the above solution can shovel up the soil, then crush it, scatter it back to the ground by the swing of the swing pipe, and spray liquid medicine during the scattering process, since the crushed soil is directly scattered by the swing of the swing pipe in the above solution, the soil directly flies out over a large area during the scattering process, and the time passing through the liquid medicine spraying position is short, which easily leads to insufficient contact between the soil and the liquid medicine, affecting the improvement effect. Summary of the Invention

[0005] The purpose of the present invention is to provide an agricultural soil improvement operation device to solve the technical problem of insufficient contact effect between the soil and the sprayed soil improvement liquid medicine during the agricultural soil improvement process in the prior art.

[0006] The technical problem to be solved by the present invention can be achieved through the following technical solutions:

[0013] As a further scheme of the present invention: The soil conveying mechanism includes a central column and an inclined channel. The inlet port is opened at the top of the central column. The rotating cylinder is rotatably connected to the central column in a matching manner. The inclined channel is opened inside the central column and is communicated with the inlet port. The side of the inclined channel close to the turning mechanism is an opening.

[0014] As a further scheme of the present invention: The reciprocating swing mechanism includes a fixed frame and a swing plate. The fixed frame is fixedly arranged below the opening side of the inclined channel; the swing plate is rotatably connected in the fixed frame through a rotating shaft. One side of the swing plate is used to receive the soil discharged by the soil conveying mechanism, and a baffle plate is fixedly connected to the other side. The swing plate is connected to the driving gear through a transmission mechanism in a matching manner. A transition mechanism matching the swing plate is also arranged on the opening side of the inclined channel.

[0015] As a further solution of the present invention: The transition mechanism includes a through box, a lifting sliding frame and an inclined guide plate. The through box is fixedly arranged between the outlet side of the inclined channel and the fixed frame. The lifting sliding frame is slidably arranged inside the fixed frame. Limiting sliding grooves are opened on both inner walls of the two sides of the fixed frame. The two sides of the lifting sliding frame are respectively slidably connected with the corresponding limiting sliding grooves through sliders. The inclined guide plate is obliquely arranged on the lifting sliding frame, and the lower side of the inclined guide plate is movably connected with one side of the lifting sliding frame close to the swing plate through a rebound hinge. A bending spring is connected between the higher side of the inclined guide plate and the lifting sliding frame. One side of the top of the lifting sliding frame is also fixedly connected with an intercepting plate for blocking the outlet side of the inclined channel. A push rod aligned and matched with the inclined guide plate is fixedly connected to the side of the swing plate away from the material blocking plate.

[0016] As a further solution of the present invention: An arc-shaped inclined material guiding frame is arranged on the side of the fixed frame away from the material blocking plate. The side of the swing plate away from the material blocking plate is aligned and matched with the arc-shaped inclined material guiding frame.

[0017] As a further solution of the present invention: A connecting guide rail is fixedly connected to the bottom of the fixed frame. The arc-shaped inclined material guiding frame is slidably connected with the connecting guide rail. One side of the bottom of the lifting sliding frame is movably connected with a linkage rod through a hinge, and the end of the linkage rod is movably connected with the arc-shaped inclined material guiding frame through a hinge.

[0018] As a further solution of the present invention: The transmission mechanism includes a transmission shaft, a first linkage gear, a second linkage gear and a synchronous rotating plate. The transmission shaft is coaxially and fixedly connected with the driving gear. The first linkage gear is coaxially and fixedly connected to the transmission shaft. A gear rack is fixedly arranged above one side of the fixed frame. The second linkage gear is rotatably connected to the gear rack through a rotating shaft, and the second linkage gear meshes with the first linkage gear. The second linkage gear is coaxially and fixedly connected with a rotating arm. The synchronous rotating plate is arranged outside the fixed frame, and one end of the synchronous rotating plate is coaxially and fixedly connected with the swing plate. The synchronous rotating plate is arranged below the rotating arm in a matching manner.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention relies on the rotating digging shovel to dig up the soil and conducts it to the inclined guide plate in the through box through the inclined channel of the central column. During the rotation of the digging shovel, the arranged transmission shaft drives the rotating arm to rotate through the first linkage gear and the second linkage gear, and relies on the different extrusion effects of the rotating arm on the synchronous rotating plate. In this way, the synchronous rotating plate drives the swing plate to continuously swing back and forth and deflect. Each time the side of the swing plate connected with the material blocking plate drops, the other side of the swing plate will push out the soil on the inclined guide plate and fall on the swing plate, and then the swing plate swings back, so as to facilitate the soil to flow and roll back and forth within the range of the liquid medicine spraying for a certain distance, thereby facilitating the improvement of the contact effect between the soil and the sprayed liquid medicine.

[0021] 2. The lifting sliding frame and the inclined guide plate arranged in the through box of the present invention will only rise to discharge the soil when the swinging plate tilts on the side away from the material baffle. In this way, it can be ensured that the soil falling on the swinging plate first flows and tumbles towards the side where the material baffle is located, and then flows out from the other side of the swinging plate, so as to ensure that the soil falling each time can achieve a round-trip flow and tumbling.

[0022] 3. Every time the lifting sliding frame and the inclined guide plate of the present invention rise under the pushing action of the swinging plate and then slide down to reset, the lifting sliding frame can rely on the linked rod connected to push and pull the arc-shaped inclined material guide frame to reciprocate along the connecting guide rail. In this way, the arc-shaped inclined material guide frame will scatter the soil after spraying the liquid medicine during the movement process.

[0023] 4. During the rotation of the rotating cylinder with the distributed digging shovels of the present invention, the rollers coaxially connected to the rotating shear parts arranged in the digging shovels roll along the arc guide bars, so as to facilitate the rotation of the rotating shear parts together to break the large soil blocks in the digging shovels and prevent the soil blocks from being blocked in the digging shovels and unable to effectively enter the inclined channel.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1 - 8 shown, an agricultural soil improvement operation device includes a mounting frame 1 and a soil excavation processing mechanism. The mounting frame 1 can be provided with screw holes or other connecting parts convenient for fixed connection, which is convenient for fixed connection to the corresponding agricultural tractor, such as being installed and connected to a tractor, or being specifically used for traction and driving the soil improvement operation device. One side of the mounting frame 1 is fixedly connected with a hydraulic telescopic rod 2 for driving the lifting of the soil excavation processing mechanism. The telescopic end of the hydraulic telescopic rod 2 is vertically downward and is fixedly connected with a fixed hanging frame 3, and the soil excavation processing mechanism is connected to the telescopic end of the hydraulic telescopic rod 2 through the fixed hanging frame 3;

[0036] The soil excavation processing mechanism includes a soil picking mechanism, a turning mechanism, and a liquid spraying mechanism 9; the soil picking mechanism includes a rotary soil conveying mechanism and a soil conduction mechanism; the rotary soil conveying mechanism is rotatably arranged outside the soil conduction mechanism, and the rotary soil conveying mechanism excavates the ground soil through rotational movement and conveys it into the soil conduction mechanism;

[0037] The turning mechanism is arranged at the discharge side of the soil conduction mechanism in cooperation, and the turning mechanism includes a reciprocating swing mechanism for receiving the soil discharged by the soil conduction mechanism, and a transmission mechanism is arranged between the rotary soil conveying mechanism and the reciprocating swing mechanism. During the rotation of the rotary soil conveying mechanism, the transmission mechanism drives the reciprocating swing mechanism to reciprocate, so that the received soil rolls. The liquid spraying mechanism 9 is used for spraying liquid medicine on the soil on the reciprocating swing mechanism. Due to the rolling of the soil, it is convenient for the liquid medicine to fully contact the soil and improve the improvement effect.

[0038] In some specific embodiments, in combination with Figure 1 , Figure 2 and Figure 5 as shown, the rotating soil feeding mechanism includes a rotating cylinder 4, soil shovels 6 and a rotating drive mechanism. The rotating cylinder 4 is rotatably sleeved outside the soil conducting mechanism. There are multiple soil shovels 6, which are circumferentially and equidistantly fixedly distributed on the outer wall of the rotating cylinder 4. And on the side wall of the rotating cylinder 4 corresponding to each soil shovel 6, there is a through port. The rotating drive mechanism is used to drive the rotating cylinder 4 to rotate. In this way, when the soil shovels 6 can contact the ground soil, the soil can be dug up by rotation; at the top of the soil conducting mechanism, there is a feeding port 25 that cooperates with the through port. When each soil shovel 6 rotates with the rotating cylinder 4 and brings the soil to the top of the soil conducting mechanism, the soil can enter the soil conducting mechanism by relying on gravity through the through port and the feeding port 25.

[0039] In some specific embodiments, in order to facilitate further crushing of the soil entering the soil shovels 6 and avoid blockage, as Figure 5 shown, a plurality of rotating shear members 15 are rotatably connected to the inner side of each soil shovel 6. Each rotating shear member 15 includes a horizontal shaft and blades distributed on the horizontal shaft. And at one end of each rotating shear member 15, a roller 24 is coaxially and fixedly connected. On one side of the rotating cylinder 4, there is a semi-circular guide bar 8, and the semi-circular guide bar 8 is fixedly arranged relative to the fixed hanging frame 3. Each roller 24 cooperates with the semi-circular guide bar 8. The semi-circular guide bar 8 is concentric with the rotating cylinder 4. When each soil shovel 6 rotates with the rotating cylinder 4 to the lowest position, the contacted soil can be dug up, and then when it deflects to a higher position, the corresponding roller 24 contacts the outer wall of the semi-circular guide bar 8. Then, while the roller 24 deflects with the rotating cylinder 4, it rolls along the semi-circular guide bar 8 by itself, so as to facilitate driving the corresponding rotating shear member 15 to rotate, facilitating further crushing of the soil in the soil shovel 6 and facilitating the soil to finally fall into the soil conducting mechanism.

[0040] In some specific embodiments, referring to Figure 2 as shown, the rotating drive mechanism includes a drive motor 12, a driving gear 14 and a gear ring 13. The gear ring 13 is coaxially and fixedly connected to one end of the rotating cylinder 4. The driving gear 14 is fixedly connected to the main shaft end of the drive motor 12, and the driving gear 14 meshes with the gear ring 13. The drive motor 12 is fixedly arranged relative to the fixed hanging frame 3. The drive motor 12 drives the driving gear 14 to rotate, and the driving gear 14 rotates the gear ring 13, thereby driving the rotating cylinder 4 to rotate.

[0041] In some specific embodiments, referring to Figure 5As shown in the figure, the soil conduction mechanism includes a central column 5 and an inclined channel 7. The central column 5 is fixedly arranged relative to the telescopic end of the hydraulic telescopic rod 2. The feed port 25 is opened at the top of the central column 5. The rotating cylinder 4 is rotationally connected with the central column 5. Specifically, concentric convex rings can be arranged at both ends of the central column 5, and annular sliding grooves are opened on the inner walls at both ends of the rotating cylinder 4. The concentric convex rings are slidably connected in the annular sliding grooves, so as to ensure the rotation of the rotating cylinder 4 relative to the central column 5. The inclined channel 7 is opened inside the central column 5 and is communicated with the feed port 25. One side of the inclined channel 7 close to the turning mechanism is an opening. It should be noted that the opening side of the inclined channel 7 is the lower side. When the soil passing through the digging shovel 6 passes through the feed port 25 and enters the inclined channel 7 inside the central column 5, the soil can slide out from the opening side along the inclined inclined channel 7.

[0042] It should be noted that in order to facilitate the discharge of the soil along the inclined channel 7, a conveyor belt assembly can also be installed on the inclined channel 7 to assist in conveying by relying on the conveyor belt assembly.

[0043] In some specific implementation schemes, in combination with Figure 3 and Figure 6 As shown in the figure, the reciprocating swing mechanism includes a fixed frame 33 and a swing plate 19. The fixed frame 33 is fixedly arranged below the opening side of the inclined channel 7; the swing plate 19 is rotationally connected in the fixed frame 33 through a rotating shaft. One side of the swing plate 19 is used to receive the soil discharged from the soil conduction mechanism, and the other side is fixedly connected with a baffle plate 28. The swing plate 19 is connected with the driving gear 14 through a transmission mechanism, and a transition mechanism matching with the swing plate 19 is also arranged on the opening side of the inclined channel 7.

[0044] Among them, referring to Figure 5 and Figure 7 As shown in the figure, the transition mechanism includes a through box 10, a lifting sliding frame 34 and an inclined guide plate 16. The through box 10 is fixedly arranged between the outlet side of the inclined channel 7 and the fixed frame 33. The lifting sliding frame 34 is slidably arranged inside the fixed frame 33. Limiting sliding grooves 29 are opened on both inner walls of the fixed frame 33. Both sides of the lifting sliding frame 34 are respectively slidably connected with the corresponding limiting sliding grooves 29 through sliders. Both the through box 10 and the lifting sliding frame 34 are through structures up and down. The inclined guide plate 16 is obliquely arranged on the lifting sliding frame 34, and the lower side of the inclined guide plate 16 is movably connected with one side of the lifting sliding frame 34 close to the swing plate 19 through a resilient hinge. A stretchable and bendable bending spring 31 is connected between the higher side of the inclined guide plate 16 and the lifting sliding frame 34. The initial position of the inclined guide plate 16 is lower than the top edge of the through box 10. One side of the top of the lifting sliding frame 34 is also fixedly connected with an intercepting plate 32 for blocking the outlet side of the inclined channel 7. One side of the swing plate 19 far from the baffle plate 28 is fixedly connected with a top rod 30 aligned and matched with the inclined guide plate 16. The top rod 30 can be arranged in pairs according to actual needs.

[0045] The soil discharged from the inclined channel 7 first falls into the through box 10 and lands on the inclined guide plate 16 for temporary storage. Whenever the swing plate 19 rotates and tilts upward near one side of the through box 10, the swing plate 19 deflects upward through the ejector rod 30 to push the inclined guide plate 16. At this time, the inclined guide plate 16 first drives the lifting sliding frame 34 to slide and rise along the limit sliding groove 29. The inclined guide plate 16 then pushes the caught soil upward, and then the soil can fall onto the swing plate 19 along the inclined guide plate 16 and then slide along the inclined swing plate 19 to the side where the baffle plate 28 is located. When the inclined guide plate 16 is higher than the top edge position of the through box 10, the lifting sliding frame 34 just slides to the highest point of the limit sliding groove 29 and cannot continue to slide upward further. At this time, the swing plate 19 still maintains its deflection. In this way, the inclined guide plate 16 can be pushed by the ejector rod 30, causing the inclined guide plate 16 to deflect relative to the lifting sliding frame 34. And during this process, the bending spring 31 stretches to generate a resilience force. The deflected inclined guide plate 16 facilitates the full dumping of the soil. And when the lifting sliding frame 34 and the inclined guide plate 16 rise, the intercepting plate 32 rises synchronously and intercepts at the opening side of the inclined channel 7 to prevent the soil from continuing to be discharged at this time and directly falling between the deflected inclined guide plate 16 and the lifting sliding frame 34 without being processed. When the swing plate 19 swings back, it is convenient for the soil to slide from the side where the baffle plate 28 is located to the other side. During this process, the liquid spraying mechanism 9 sprays the liquid medicine from top to bottom, which is convenient for spraying the liquid medicine on the soil moving back and forth, improving the contact effect between the soil and the liquid medicine, and thus improving the improvement effect. And after the swing plate 19 swings back, the set lifting sliding frame 34 can slide down and reset along the limit sliding groove 29 by gravity. At the same time, the inclined guide plate 16 can also rotate and reset relative to the lifting sliding frame 34 by the resilience force of the bending spring 31, facilitating the re-catching of the subsequent soil.

[0046] In order to facilitate the effective rolling of the soil during the flow along the swing plate 19, a plurality of ball grooves can be evenly distributed on the surface layer of the swing plate 19. By relying on the ball grooves, the passing soil has undulations, so as to facilitate tumbling and further improve the contact effect between the soil and the sprayed liquid medicine.

[0047] It should be noted that the liquid spraying mechanism 9 includes a liquid medicine tank, a delivery pump for pumping out the liquid medicine in the liquid medicine tank, and nozzles distributed above the swing plate 19. And pressure sensing switches electrically connected to the delivery pump are distributed on the bottom surface of the inclined guide plate 16. When the ejector rod 30 abuts against the bottom surface of the inclined guide plate 16, the pressure sensing switches generate an induction, causing the delivery pump to operate. The delivery pump then pumps out the liquid medicine in the liquid medicine tank and sprays it through the nozzles.

[0048] In some specific embodiments, an arc-shaped inclined material guiding frame 11 is provided on one side of the fixed frame 33 away from the material baffle 28. One side of the swing plate 19 away from the material baffle 28 is aligned and cooperated with the arc-shaped inclined material guiding frame 11. The arc-shaped inclined material guiding frame 11 is composed of an arc-shaped bottom plate and baffle plates distributed on both sides. The end of the arc-shaped inclined material guiding frame 11 is inclined and bent towards the middle position of the tail of the entire working device. When the swing plate 19 swings back each time to discharge the soil sprayed with liquid medicine, the soil falls into the arc-shaped inclined material guiding frame 11 and then falls back to the ground along the arc-shaped inclined material guiding frame 11.

[0049] In some other specific embodiments, in combination with Figure 6 and Figure 7 as shown, a connecting guide rail 18 is fixedly connected to the bottom of the fixed frame 33. The arc-shaped inclined material guiding frame 11 is slidably connected to the connecting guide rail 18. One side of the bottom of the lifting sliding frame 34 is movably connected to a linkage rod 17 through a hinge, and the end of the linkage rod 17 is movably connected to the arc-shaped inclined material guiding frame 11 through a hinge.

[0050] Each time the lifting sliding frame 34 rises, it pulls the arc-shaped inclined material guiding frame 11 to slide along the connecting guide rail 18 towards the side where the central column 5 is located through the linkage rod 17. When the lifting sliding frame 34 descends, it pushes the arc-shaped inclined material guiding frame 11 to slide back along the connecting guide rail 18 through the linkage rod 17, so as to facilitate the reciprocating sliding of the arc-shaped inclined material guiding frame 11 and facilitate the soil discharged to spread when it falls.

[0051] It should be noted that a spring can be connected between the arc-shaped inclined material guiding frame 11 and the connecting guide rail 18. When the arc-shaped inclined material guiding frame 11 slides along the connecting guide rail 18 and approaches the central column 5, the spring deforms to generate a restoring force, which facilitates the arc-shaped inclined material guiding frame 11 to drive the lifting sliding frame 34 to descend and reset. And the width of the arc-shaped inclined material guiding frame 11 is greater than the width of the fixed frame 33 to prevent the fixed frame 33 from interfering with the reciprocating movement of the arc-shaped inclined material guiding frame 11.

[0052] It also should be noted that when the digging shovel 6 rotates to the lowest position of the rotating drum 4, the lowest position of the digging shovel 6 is lower than the lowest position of the arc-shaped inclined material guiding frame 11.

[0053] In some specific embodiments, in combination with Figure 6 and Figure 8As shown, the transmission mechanism includes a transmission shaft 27, a first linkage gear 22, a second linkage gear 21 and a synchronous rotating plate 20. The transmission shaft 27 is coaxially fixedly connected to the driving gear 14. The transmission shaft 27 extends to a position close to the fixed frame 33. The first linkage gear 22 is coaxially fixedly connected to the transmission shaft 27. A gear frame 23 is fixedly arranged on one side of the fixed frame 33. It should be noted here that the gear frame 23 can be fixedly connected to the semicircular guide bar 8 or to the center column 5 according to actual needs. The second linkage gear 21 is rotatably connected to the gear frame 23 through a rotating shaft, and the second linkage gear 21 is rotatably connected to the gear frame 23 through a rotating shaft. The movable gear 21 is meshed with the first linkage gear 22, and the second linkage gear 21 is coaxially fixedly connected with a pivot arm 26. It should be noted that the pivot arm 26 and the second linkage gear 21 are perpendicular to the pivot axis connected to the second linkage gear 21, and the end of the pivot arm 26 is a spherical end. The synchronous rotating plate 20 is arranged on the outside of the fixed frame 33, and one end of the synchronous rotating plate 20 is coaxially fixedly connected to the swing plate 19, that is, the synchronous rotating plate 20 rotates synchronously with the swing plate 19, and the other end of the synchronous rotating plate 20 is parallelly aligned with one end of the swing plate 19 connected to the baffle plate 28, and the synchronous rotating plate 20 is coordinated and located below the pivot arm 26.

[0054] When the driving gear 14 drives the drum 4 to rotate, the driving gear 14 also drives the transmission shaft 27 to rotate, and the transmission shaft 27 drives the first linkage gear 22 to rotate, and the first linkage gear 22 drives the second linkage gear 21 to rotate, and the second linkage gear 21 drives the rotating arm 26 to rotate. Figure 8 From the perspective, the rotating arm 26 rotates clockwise. During the rotation of the rotating arm 26, its end squeezes and pushes the synchronous rotating plate 20, and the synchronous rotating plate 20 deflects downward, thereby driving the end of the swing plate 19 connected to the baffle plate 28 to deflect downward. When the end of the rotating arm 26 rotates through the lowest position and begins to deflect upward, the synchronous rotating plate 20 rotates due to the rotation of the inclined guide plate 16 and the downward sliding force of the lifting slide frame 34 on the swing plate 19. In this way, the synchronous rotating plate 20 remains in contact with the end of the rotating arm 26 during the rotation process, thereby preventing the synchronous rotating plate 20 and the swing plate 19 from rotating too fast and lifting the soil.

[0055] It should be noted that the soil improvement device disclosed in the present invention is for land that has been preliminarily turned over, and the disclosed shovel 6 is mainly used to dig up the bumps that have been turned over.

[0056] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0057] First, the entire working device is installed on the agricultural tractor through the mounting frame 1, and is driven to descend by the hydraulic telescopic rod 2, so that the distributed shovels 6 can descend to contact the ground soil, and the driving motor 12 is started, and the driving motor 12 drives the driving gear 14 to rotate, and the driving gear 14 rotates the gear ring 13, thereby driving the rotating drum 4 to rotate. When each shovel 6 rotates to the lowest position with the rotating drum 4, the contacted soil can be dug up, and then when it deflects to a higher position, the corresponding roller 24 contacts the outer wall of the semicircular guide bar 8, and then the roller 24 rolls along the semicircular guide bar 8 while the rotating drum 4 deflects, so as to facilitate the corresponding rotating shearing member 15 to rotate, so as to facilitate the further crushing of the soil in the shovel 6; when the shovel 6 rotates to the top of the central column 5 with the rotating drum 4, the crushed soil in the shovel 6 will enter the inner inclined channel 7 of the central column 5 through the feed port 25.

[0058] Then the soil slides into the through box 10 along the inclined channel 7 and falls on the inclined guide plate 16 for temporary storage. When the driving motor 12 drives the active gear 14 to rotate, the active gear 14 also drives the transmission shaft 27 to rotate, and the transmission shaft 27 drives the first linkage gear 22 to rotate, and the first linkage gear 22 drives the second linkage gear 21 to rotate, and the second linkage gear 21 drives the rotating arm 26 to rotate. During the rotation of the rotating arm 26, its end squeezes and pushes the synchronous rotating plate 20, and the synchronous rotating plate 20 deflects downward, thereby driving the end of the swing plate 19 connected to the baffle plate 28 to deflect downward, and at this time, the swing plate 19 rotates and tilts up near the side of the through box 10, so that the swing plate 19 deflects upward through the push rod 30 to push the inclined guide plate 1 6. At this time, the inclined guide plate 16 first slides and rises along the limiting slide groove 29 with the lifting slide frame 34, and the inclined guide plate 16 pushes the received soil upward, and then the soil can fall along the inclined guide plate 16 to the swing plate 19, and then slide along the inclined swing plate 19 to the side where the blocking plate 28 is located. When the inclined guide plate 16 is higher than the top edge position of the through box 10, the lifting slide frame 34 just slides to the highest point of the limiting slide groove 29 and cannot continue to slide further upward. At this time, the swing plate 19 still maintains deflection, so that the inclined guide plate 16 can be pushed by the push rod 30, causing the inclined guide plate 16 to deflect relative to the lifting slide frame 34, and in this process, the bending spring 31 is stretched to generate a rebound force, and the deflected inclined guide plate 16 is convenient for fully dumping the soil;

[0059] When the lifting slide frame 34 and the inclined guide plate 16 are lifted, the interception plate 32 is lifted synchronously and intercepted at the opening side of the inclined channel 7 to prevent the soil from continuing to be discharged and falling directly from the gap between the deflected inclined guide plate 16 and the lifting slide frame 34 and being unable to be processed;

[0060] When the end of the swing arm 26 rotates through the lowest position and begins to deflect upward, the synchronous rotating plate 20 can rotate, and then the swing plate 19 can also rotate. Thus, the inclined guide plate 16 rotates by relying on the resilience of the bending spring 31, and the lifting sliding frame 34 slides downward and resets by gravity. During the deflection process of the swing plate 19, the liquid spraying mechanism 9 sprays the liquid medicine from top to bottom, which is convenient for spraying the liquid medicine on the soil moving back and forth on the swing plate 19, improving the contact effect between the soil and the liquid medicine, thereby enhancing the improvement effect. After the swing plate 19 swings back, the soil slides down along the swing plate 19 into the arc-shaped inclined material guiding frame 11, and then falls back to the ground along the arc-shaped inclined material guiding frame 11. And because both the lifting sliding frame 34 and the inclined guide plate 16 are reset, it is convenient to catch the subsequent soil again. Then the swing plate 19 repeats the above movement, so as to catch the soil each time and swing reciprocally, making the soil tumble and facilitating contact with the sprayed liquid medicine.

[0061] It should be noted that each time the lifting sliding frame 34 rises, it pulls the arc-shaped inclined material guiding frame 11 to slide along the connecting guide rail 18 towards the side close to the central column 5 through the linkage rod 17. When the lifting sliding frame 34 descends, it pushes the arc-shaped inclined material guiding frame 11 to slide back along the connecting guide rail 18, so as to facilitate the reciprocating sliding of the arc-shaped inclined material guiding frame 11 and make the discharged soil disperse when it falls.

[0062] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and should not be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
