Description

Technical Field

[0001] The present invention relates to the technical field of saline-alkali land improvement, and specifically to a tillage and cultivation device and method for reducing alkalinity and improving fertility of moderately and severely saline-alkali cultivated land. Background Technique

[0002] Moderately and severely saline-alkali cultivated land is an important factor affecting global agricultural sustainable development. The high salt content and alkaline conditions in its soil severely restrict the growth and yield of crops. To address this challenge, the research and application of tillage and cultivation devices for reducing alkalinity and improving fertility are particularly important. Among them, powdered amendments, as an efficient and convenient soil improvement means, have received extensive attention in recent years. These amendments significantly improve the fertility and suitability of saline-alkali soil through various mechanism of action such as adjusting soil pH, increasing organic matter content, and improving soil permeability. In the design of tillage and cultivation devices, functions such as deep plowing and loosening of soil, precise fertilization, and water-saving irrigation are integrated to ensure that the powdered amendments can be evenly and efficiently applied to the soil.

[0003] In the existing tillage and cultivation devices for reducing alkalinity and improving fertility of moderately and severely saline-alkali cultivated land, during use, within the same improved area, there may be a need to increase or decrease the amount of amendments locally. For example, in the way of spreading lime, if the method of quantitatively spreading powdered amendments is adopted, it may not only cause waste of amendments but also affect the effect of soil improvement, and it is inconvenient to use. Therefore, in view of the above current situation, there is an urgent need to develop a tillage and cultivation device and method for reducing alkalinity and improving fertility of moderately and severely saline-alkali cultivated land to overcome the deficiencies in current practical applications.

[0043] Step 1: While the external traction device drives the improvement tillage device to move on the ground through the connecting frame, start the driving motor, and the driving motor drives the rotating shaft and the soil turning device to rotate;

[0044] Step 2: During the rotation of the rotating shaft, it will also drive the eccentric control ring plate to rotate synchronously. When the outer side wall of the eccentric control ring plate contacts the driven pressure roller, it will push the driven pressure roller and the lifting and adjusting plate to move upward, and drive the lifting connecting rod and the sliding sealing plate to move upward synchronously.

[0047] Repeat Step 3 until the purpose of fully improving the soil is achieved.

[0048] Compared with the prior art, the beneficial effects of the present invention are:

[0049] After the improver is stored on the discharge control bin of the storage discharge bin, wherein the bottom wall of the discharge control bin adopts an inclined structure, so that the improver gathers near the feeding port under its own gravity, which is convenient for the subsequent outflow of the improver. Then, during the horizontal movement of the improved tillage equipment, the displacement control component is started, and according to the tilling speed of the improved tillage equipment, the improver can be automatically discharged into the soil surface to be tilled intermittently through the discharge component. By means of intermittent discharge, the impact on crops can be reduced, the nutrient utilization rate can be improved, and the waste of the improver can be avoided. In addition, under the continuous detection of the conductivity sensor, wherein the conductivity sensor can also be in the form of a hardness sensor to identify the areas with serious soil compaction. Of course, multiple types of sensors can also be combined with each other to ensure the accuracy of detection, which will not be elaborated here. When it is detected that the soil salt content changes, for example, when it is detected that the soil pollution is relatively serious, the conductivity sensor will control the displacement control component to act to increase the time and amount of the improver discharged into the discharge component, and the longer the discharge time, the greater the discharge amount will be, so as to achieve the purpose of fully improving the soil. On the contrary, when it is detected that the soil pollution is relatively slight, the time and amount of the improver discharged into the discharge component will be correspondingly reduced. The operation is simple. For the same improved area, if there is a need to increase or decrease the improver locally, by adjusting the intermittently discharged amount of the improver, not only the waste of the improver can be avoided, but also the effect of soil improvement can be improved, which provides convenience for users.

[0066] The following describes in detail the specific implementation of the present invention in conjunction with specific embodiments.

[0068] A discharge control bin 27 is fixedly installed in the storage and discharge box 2, and a plurality of discharge openings 35 are further opened on the discharge control bin 27, and a sliding sealing plate 30 is slidably installed on each discharge opening 35;

[0069] And an improvement control mechanism, the improvement control mechanism is respectively connected to the improved tillage device 1 and the storage and discharge box 2, and is respectively connected to the discharge control bin 27 and the sliding sealing plate 30. Among them, the improvement control mechanism includes a conductivity sensor 9, a discharge amount control component and a discharge component;

[0070] The conductivity sensor 9 is fixedly installed on the improved tillage device 1, the discharge amount control component is respectively connected to the improved tillage device 1 and the sliding sealing plate 30, and is electrically connected to the conductivity sensor 9, and the discharge component is respectively connected to the storage and discharge box 2 and the discharge control bin 27, and the discharge component is also arranged close to the discharge opening 35.

[0071] Please refer to Figures 1-14 , and further includes: a connecting frame 8, the connecting frame 8 is fixedly connected to the improved tillage device 1 and the storage and discharge box 2 respectively;

[0072] A flip cover 5 is rotatably installed on the top of the storage and discharge box 2;

[0073] And an installation base 4, the number of the installation bases 4 is multiple, and multiple installation bases 4 are all fixedly installed on the improved tillage device 1.

[0074] It further includes: an indicator 7, the indicator 7 is fixedly installed on the improved tillage device 1 and is electrically connected to the conductivity sensor 9;

[0075] A heating and drying device 6, which is fixedly installed on the side wall of the storage and discharging box 2;

[0076] And sliding seats 29. The number of the sliding seats 29 is multiple. The multiple sliding seats 29 are all fixedly installed on the discharging control bin 27 and are respectively slidably connected with the multiple sliding sealing plates 30.

[0077] During the process of reducing soil alkalinity and improving soil fertility in moderately and severely saline-alkali cultivated land, first, the soil improvement device 1 can be connected to an external traction device through a connecting frame 8. Under the pulling action of the external traction device, the soil improvement device 1 can perform soil improvement operations on a specified area. Before the soil improvement device 1 moves, the staff can open the flip cover 5 and temporarily store the soil conditioner in the storage and discharging box 2. At this time, starting the heating and drying device 6 can prevent the soil conditioner in the storage and discharging box 2 from caking due to moisture or other reasons, affecting the subsequent fluidity and thus causing blockage. In addition, according to the needs of use, rollers can be installed at multiple installation bases 4 to ensure the stable movement of the soil improvement device 1 on the ground, which will not be elaborated here;

[0078] After the soil conditioner is stored in the discharging control bin 27 of the storage and discharging box 2, wherein the bottom wall of the discharging control bin 27 adopts an inclined structure, so that the soil conditioner gathers near the discharging opening 35 under its own gravity, facilitating the subsequent outflow of the soil conditioner. Then, during the horizontal movement of the soil improvement device 1, starting the discharge control assembly can automatically make the soil conditioner intermittently discharged onto the soil surface to be turned over through the discharging assembly according to the soil turning speed of the soil improvement device 1. Through the intermittent discharge method, the impact on crops can be reduced, the nutrient utilization rate can be improved, and the waste of the soil conditioner can be avoided. In addition, under the continuous detection of the conductivity sensor 9, wherein the conductivity sensor 9 can also be in the form of a hardness sensor to identify areas with serious soil compaction. Of course, multiple types of sensors can also be used in combination to ensure the accuracy of detection, which will not be elaborated here. When it is detected that the soil salt content changes, for example, when it is detected that the soil pollution is relatively serious, the conductivity sensor 9 will control the discharge control assembly to act to increase the time and amount of the soil conditioner discharged into the discharging assembly, and the longer the discharge time, the greater the discharge amount, so as to achieve the purpose of fully improving the soil. On the contrary, when it is detected that the soil pollution is relatively slight, the time and amount of the soil conditioner discharged into the discharging assembly will be correspondingly reduced. The operation is simple. For the same improved area, if there is a need to increase or decrease the amount of the soil conditioner locally, by adjusting the intermittent discharge amount of the soil conditioner, not only can the waste of the soil conditioner be avoided, but also the effect of soil improvement can be improved, providing convenience for users.

[0079] In an embodiment of the present invention, please refer toFigures 1-14 , the material discharging assembly includes:

[0080] An inclined material conveying cylinder 31, which is fixedly connected to the storage and discharging box 2 and the discharging control bin 27 respectively, and is arranged close to the discharging port 35;

[0081] A material spraying bin 33, which is fixedly connected to the inclined material conveying cylinder 31, and is communicated with the inclined material conveying cylinder 31 through an intermediate material seam 37;

[0082] And a plurality of spraying ports 34, the number of the spraying ports 34 is multiple, the multiple spraying ports 34 are evenly distributed on the material spraying bin 33, and are fixedly connected to the improved tillage equipment 1, and the outlet of the spraying port 34 is also arranged close to the conductivity sensor 9.

[0084] A driving motor 3, which is fixedly installed on the improved tillage equipment 1;

[0085] A rotating shaft 10, which is rotatably connected to the improved tillage equipment 1, and is also fixedly connected to the output end of the driving motor 3. Wherein, a plurality of soil turning devices 11 are also fixedly arranged on the rotating shaft 10;

[0086] An eccentric control ring plate 12, which is sleeved on the rotating shaft 10 and is fixedly connected to the rotating shaft 10 through a bracket 14;

[0087] And a lifting amplitude control unit, which is respectively connected to the improved tillage equipment 1 and the rotating shaft 10, and is connected to the eccentric control ring plate 12.

[0088] The lifting amplitude control unit includes:

[0089] A rotating support 21, which is rotatably connected to the rotating shaft 10 and is fixedly connected to the improved tillage equipment 1, and a connecting support rod 13 is also fixedly installed on the rotating support 21;

[0090] A guiding control sleeve 15, which is fixedly installed on the connecting support rod 13;

[0091] A lifting adjustment plate 16, which penetrates through the guiding control sleeve 15 and is slidably connected to the guiding control sleeve 15, and a lifting connecting rod 28 is also fixedly installed at the top end of the lifting adjustment plate 16, and the lifting connecting rod 28 is fixedly connected to the sliding sealing plate 30;

[0092] Wherein, an elastic lever 36 is fixedly installed on the sliding plugging plate 30, and the elastic lever 36 is located in the material discharging port 35;

[0093] And a reset detection module and a lifting control module, the reset detection module is respectively connected to the guiding control sleeve 15 and the lifting adjustment plate 16, the lifting control module is respectively connected to the eccentric control ring plate 12 and the lifting adjustment plate 16, and is electrically connected to the conductivity sensor 9.

[0094] The reset detection module includes:

[0095] Guiding sliding cavities 26, which are respectively located on both sides of the guiding control sleeve 15;

[0096] Detection connection blocks 25, the number of the detection connection blocks 25 is two, the two detection connection blocks 25 are respectively fixedly installed on the two side walls of the lifting adjustment plate 16, and are respectively slidably installed in the guiding sliding cavities 26;

[0097] And a reset spring 24, the reset spring 24 is located in the guiding sliding cavity 26, and both ends of the reset spring 24 are respectively fixedly connected to the detection connection block 25 and the guiding sliding cavity 26.

[0098] The lifting control module includes:

[0099] Detection support rollers 18, the detection support rollers 18 are rotatably installed on the lifting adjustment plate 16, and are detachably connected to the inner side wall of the eccentric control ring plate 12;

[0100] Adjustment notches 20, the adjustment notches 20 are formed on the lifting adjustment plate 16, and a moving sliding plate 22 is slidably installed in the adjustment notches 20, one end of the moving sliding plate 22 is rotatably installed with a driven pressure roller 23, and the driven pressure roller 23 is detachably connected to the outer side wall of the eccentric control ring plate 12;

[0101] A telescopic cylinder 17, the telescopic cylinder 17 is fixedly installed on the lifting adjustment plate 16;

[0102] And a telescopic rod 19, one end of the telescopic rod 19 is fixedly connected to the output end of the telescopic cylinder 17, and the other end of the telescopic rod 19 is fixedly connected to the moving sliding plate 22.

[0103] During the movement of the improved tillage device 1, the driving motor 3 is started, which can drive the rotation of the rotating shaft 10 and drive multiple soil-turning devices 11 to turn the soil. During this process, the spread of the modifier is carried out, which can make the soil and the modifier fully mixed and contacted, and can improve the uniformity of the mixing. In addition, during the rotation of the rotating shaft 10, it can also drive the eccentric control ring plate 12 to rotate synchronously. Then, under the action of its own structure of the eccentric control ring plate 12, the eccentric control ring plate 12 will intermittently contact the detection support roller 18 and the driven pressure roller 23. When the eccentric control ring plate 12 contacts the driven pressure roller 23, it will push the lifting adjustment plate 16 to move upward in the guiding control sleeve 15, and the lifting adjustment plate 16 will drive the lifting connecting rod 28 to move upward. Then, the lifting connecting rod 28 will drive multiple sliding plugging plates 30 to move upward stably synchronously in the sliding seat 29. Among them, the number of the eccentric control ring plate 12 and the lifting adjustment plate 16 can be two sets, which are respectively located at both ends of the rotating shaft 10 to drive the two ends of the lifting connecting rod 28 to move upward synchronously, so as to ensure the smoothness of the sliding of the sliding plugging plate 30. This will not be elaborated here. When the sliding plugging plate 30 moves upward and gradually separates from the discharge port 35, the modifier gathered in the discharge control bin 27 will flow outward through the discharge port 35. Among them, during the movement of the sliding plugging plate 30, it will also drive the elastic lever 36 to move upward synchronously. Under the disturbing action of the elastic lever 36, it can prevent the modifier from being blocked at the discharge port 35, so as to ensure the smooth discharge of the modifier. After the modifier enters the inclined feeding cylinder 31, it will finally enter the spraying bin 33 through the intermediate material seam 37 and be discharged onto the soil surface to be tilled through multiple spraying ports 34, thus completing the purpose of intermittent discharging;

[0104] When the conductivity sensor 9 detects a change in the soil salt content, the conductivity sensor 9 controls the start of the telescopic cylinder 17. The telescopic cylinder 17 then pushes or pulls the telescopic rod 19 to move. The telescopic rod 19 drives the moving slide plate 22 to slide within the adjustment notch 20, thereby changing the position of the driven pressure roller 23. As the eccentric control ring plate 12 continues to rotate, the contact time between the eccentric control ring plate 12 and the driven pressure roller 23 may be advanced or delayed. This can change the length of time the sliding sealing plate 30 separates from the material discharge port 35 and the amount of the modifier discharged through the material discharge port 35. Thus, when there is a local need to increase or decrease the modifier in the same improvement area, the discharge amount of the modifier can be adaptively adjusted. At the same time, by detecting the rotation time period of the detection support roller 18 and the driven pressure roller 23, it can be determined whether the equipment is operating normally. Additionally, a shock-proof pad in the form of sponge or the like is provided on the surface of the eccentric control ring plate 12 to prevent large collisions and damage between components. And when the lifting adjustment plate 16 slides within the guiding control sleeve 15, under the elastic action of the return spring 24, during the rotation of the eccentric control ring plate 12, the lifting adjustment plate 16 can return to its original position. Among them, the sliding mode between the detection connection block 25 and the guiding sliding cavity 26 can adopt the form of damped sliding to prevent the lifting adjustment plate 16 from shaking or jittering during lifting. Details are not elaborated here.

[0105] In one embodiment of the present invention, please refer to Figures 1-14 , further comprising: an air pump 32. The number of the air pumps 32 is multiple. Multiple said air pumps 32 are fixedly installed on the inclined material conveying cylinder 31 and are respectively connected to the spraying material bin 33 through multiple air pipes;

[0106] Among them, the air pump 32 is also electrically connected to the detection connection block 25.

[0107] After the eccentric control ring plate 12 pushes the driven pressure roller 23 to move upward, the lifting and adjusting plate 16 will also move upward synchronously. At this time, the sliding sealing plate 30 slides upward, and the material discharge port 35 is opened for discharging. Then, the conditioner will enter the inclined feeding cylinder 31 and the spraying bin 33 under its own gravity. In addition, when the lifting and adjusting plate 16 moves upward, the return spring 24 will gradually be in a stretched state, and the tension detected by the detection connecting block 25 will increase. At this time, the sensor on the detection connecting block 25 will control the air pump 32 to stop. On the contrary, when the eccentric control ring plate 12 continues to rotate and the lifting and adjusting plate 16 moves downward under the tension of the return spring 24, the sliding sealing plate 30 will seal the material discharge port 35 again. At this time, the tension detected by the sensor on the detection connecting block 25 becomes smaller, so that the air pump 32 can be immediately controlled to start. The high-pressure gas generated by the air pump 32 can have a greater impact on the conditioner that has accumulated in the spraying bin 33. Among them, by delaying the start of the air pump 32, on the one hand, it can provide sufficient time for the conditioner to flow from the inclined feeding cylinder 31 into the spraying bin 33, so that inflation and drainage spraying can be carried out after almost all the conditioner has accumulated in the spraying bin 33. On the other hand, inflation can be carried out after the sliding sealing plate 30 completely seals the material discharge port 35 again, avoiding the influence of air flow on the conditioner in the discharge control bin 27. In addition, through the set intermediate material gap 37, the backflow of the conditioner in the spraying bin 33 can also be avoided, which will not be elaborated here (in addition, through the set detection support roller 18, it can also play a detection role, that is, when the detection support roller 18 rotates, it proves that the eccentric control ring plate 12 has completely separated from the driven pressure roller 23. At this time, the sliding sealing plate 30 completely seals the material discharge port 35, which can further ensure the smooth operation of the equipment). Then, under the action of the air flow, a certain amount of conditioner, especially when the amount is large, can be evenly spread on the soil surface, ensuring the full mixing of the conditioner and the soil. And because the spraying port 34 is arranged in front of and on both sides of the rotary tillage tool, this position is usually where the soil is turned up and broken. Therefore, when the soil is lifted, high-pressure spraying of the conditioner can be carried out, and the conditioner can be further mixed into the soil, avoiding the conditioner only existing on the surface of the soil, which is beneficial to further improving the effect of soil improvement.

[0108] A cultivation method for reducing alkalinity and improving fertility of moderately and severely saline-alkali cultivated land uses the moderately and severely saline-alkali cultivated land reducing alkalinity and improving fertility cultivation device as described above, and specifically includes the following steps:

[0109] Step 1: While the external traction device drives the improved tillage device 1 to move on the ground through the connecting frame 8, start the drive motor 3, and the drive motor 3 will drive the rotating shaft 10 and the soil turning device 11 to rotate;

[0110] Step 2: During the rotation of the rotating shaft 10, the eccentric control ring plate 12 will also be driven to rotate synchronously. When the outer side wall of the eccentric control ring plate 12 contacts the driven pressure roller 23, it will push the driven pressure roller 23 and the lifting adjustment plate 16 upward, and drive the lifting connecting rod 28 and the sliding sealing plate 30 to move upward synchronously. During the process of the sliding sealing plate 30 separating from the material discharge port 35, the powdery modifier in the discharge control bin 27 enters the inclined material transfer cylinder 31 through the opening of the material discharge port 35, realizing intermittent discharging.

[0111] Step 3: The powdery modifier entering the inclined material transfer cylinder 31 is finally sprayed onto the surface of the soil to be turned over through a plurality of spray ports 34.

[0112] Step 4: In Step 2, when the conductivity sensor 9 detects that the salt content in a local position is too high or too low, the conductivity sensor 9 will control the telescopic cylinder 17 to push or pull the telescopic rod 19 to move, and drive the moving slide plate 22 to move synchronously in the adjustment slot 20, thereby changing the position of the driven pressure roller 23, and finally changing the contact time between the driven pressure roller 23 and the eccentric control ring plate 12 and the lifting amplitude of the eccentric control ring plate 12 pushing the driven pressure roller 23 and the lifting adjustment plate 16, so as to change the amount of the powdery modifier flowing out from the material discharge port 35.

[0113] Repeat Step 3 to achieve the purpose of fully improving the soil.
