DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0033] See also Figure 1-Figure 14The embodiment of the present invention provides a cultivation device for reducing alkali and improving fertilizer in moderately and severely salinized cultivated land, comprising an improved farming device 1, on which a storage and discharge box 2 is fixedly installed, and further comprising: A discharge control bin 27, the discharge control bin 27 is fixedly installed in the storage discharge box 2, and a plurality of discharge ports 35 are provided on the discharge control bin 27, and a sliding blocking plate 30 is slidably installed on each of the discharge ports 35; and an improved control mechanism, the improved control mechanism is respectively connected to the improved tillage equipment 1 and the storage discharge box 2, and is respectively connected to the discharge control bin 27 and the sliding blocking plate 30, wherein the improved control mechanism includes a conductivity sensor 9, a discharge control component and a discharge component; The conductivity sensor 9 is fixedly mounted on the improved tillage equipment 1, the displacement control assembly is respectively connected to the improved tillage equipment 1 and the sliding sealing plate 30, and is electrically connected to the conductivity sensor 9, the discharge assembly is respectively connected to the storage discharge box 2 and the discharge control bin 27, and the discharge assembly is also arranged close to the discharge port 35.

[0034] See also Figure 1-Figure 14 , further comprising: a connecting frame 8, wherein the connecting frame 8 is fixedly connected to the improved tillage equipment 1 and the storage discharge box 2 respectively; A flip cover 5, the flip cover 5 is rotatably mounted on the top of the storage and discharge box 2; And a mounting base 4, the number of the mounting base 4 is multiple, and the multiple mounting bases 4 are all fixedly mounted on the improved farming equipment 1.

[0035] It also includes: an indicator 7, which is fixedly mounted on the improved farming equipment 1 and electrically connected to the conductivity sensor 9; A heating and drying device 6, wherein the heating and drying device 6 is fixedly mounted on a side wall of the storage and discharge box 2; And a slide seat 29, the number of the slide seats 29 is multiple, and the multiple slide seats 29 are all fixedly installed on the discharge control bin 27, and are slidably connected to the multiple sliding sealing plates 30 respectively.

[0036] In the process of reducing alkali and improving fertilizer for medium-to-severe salinized farmland, first, the improved tillage equipment 1 can be connected to the external traction equipment through the connecting frame 8. Under the pulling action of the external traction equipment, the improved tillage equipment 1 can perform soil improvement operations in the designated area. Before the improved tillage equipment 1 moves, the staff can open the flip cover 5 and temporarily store the improver in the storage discharge box 2. At this time, the heating and drying equipment 6 is started to prevent the improver in the storage discharge box 2 from agglomerating due to moisture and other reasons, affecting the subsequent fluidity and causing blockage. In addition, according to the needs of use, rollers can be installed at multiple mounting bases 4 to ensure that the improved tillage equipment 1 moves smoothly on the ground, which will not be described in detail here. After the improver is stored in the discharge control bin 27 in the storage discharge box 2, the bottom wall of the discharge control bin 27 adopts an inclined structure so that the improver can be gathered near the discharge port 35 under the action of its own gravity, which is convenient for the subsequent outflow of the improver. Then, during the horizontal movement of the improved tillage equipment 1, the displacement control component is started, and the improver can be automatically discharged through the discharge component intermittently onto the surface of the soil to be turned over according to the speed of the improved tillage equipment 1 turning over the soil. Through intermittent discharge, the impact on crops can be reduced, the nutrient utilization rate can be improved, and the waste of improvers can be avoided. In addition, under the continuous detection of the conductivity sensor 9, the conductivity sensor 9 can also be a hardness sensor to identify areas with severe soil compaction. Of course, multiple types of sensors can also be used. The sensors are used in combination with each other to ensure the accuracy of detection. I will not go into details here. When a change in soil salt content is detected, for example, when serious soil pollution is detected, the conductivity sensor 9 will control the displacement control component 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, so as to achieve the purpose of fully improving the soil. On the contrary, when it is detected that the soil pollution is relatively light, the time and amount of the improver discharged into the discharge component will be reduced accordingly. The operation is simple. For the same improved area, if there is a local need to increase or decrease the demand for improvers, by adjusting the intermittent discharge of the improver dosage, not only can the waste of improvers be avoided, but also the effect of soil improvement can be improved, which provides convenience for users.

[0037] In one embodiment of the present invention, see Figure 1-Figure 14 , the discharge assembly comprises: An inclined material transfer cylinder 31, which is fixedly connected to the storage discharge box 2 and the discharge control bin 27, respectively, and is disposed close to the discharge port 35; A spraying bin 33, wherein the spraying bin 33 is fixedly connected to the inclined material transfer cylinder 31, and the spraying bin 33 is connected to the inclined material transfer cylinder 31 through an intermediate material gap 37; And a spray port 34 , the number of the spray ports 34 is multiple, the multiple spray ports 34 are evenly distributed on the spray bin 33 , and are fixedly connected to the improved farming equipment 1 , and the outlet of the spray port 34 is also arranged close to the conductivity sensor 9 .

[0038] See also Figure 1-Figure 14 , the displacement control assembly comprises: A driving motor 3, wherein the driving motor 3 is fixedly mounted on the improved farming equipment 1; A rotating shaft 10, wherein the rotating shaft 10 is rotatably connected to the improved tillage equipment 1, and the rotating shaft 10 is also fixedly connected to the output end of the driving motor 3, wherein a plurality of soil turning equipment 11 are also fixedly arranged on the rotating shaft 10; An eccentric control ring plate 12, wherein the eccentric control ring plate 12 is sleeved on the rotating shaft 10 and is fixedly connected to the rotating shaft 10 via a bracket 14; And a lifting amplitude control unit, which is respectively connected to the improved farming equipment 1 and the rotating shaft 10, and is connected to the eccentric control ring plate 12.

[0039] The lifting range control unit comprises: A rotating support 21, wherein the rotating support 21 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 mounted on the rotating support 21; A guide control sleeve 15, wherein the guide control sleeve 15 is fixedly mounted on the connecting support rod 13; A lifting adjustment plate 16, wherein the lifting adjustment plate 16 passes through the guide control sleeve 15 and is slidably connected to the guide control sleeve 15, and a lifting connecting rod 28 is fixedly installed on the top of the lifting adjustment plate 16, and the lifting connecting rod 28 is fixedly connected to the sliding blocking plate 30; The sliding blocking plate 30 is also fixedly mounted with an elastic lever 36, and the elastic lever 36 is located in the discharge port 35; And a reset detection module and a lifting control module, the reset detection module is respectively connected to the guide 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.

[0040] The reset detection module comprises: A guide sliding cavity 26, wherein the guide sliding cavity 26 is respectively located on both sides of the guide control sleeve 15; Detection connection blocks 25, the number of the detection connection blocks 25 is two, the two detection connection blocks 25 are respectively fixedly mounted on the two side walls of the lifting adjustment plate 16, and are respectively slidably mounted in the guide sliding cavity 26; And a return spring 24, wherein the return spring 24 is located in the guide sliding cavity 26, and both ends of the return spring 24 are fixedly connected to the detection connection block 25 and the guide sliding cavity 26 respectively.

[0041] The lifting control module comprises: A detection support roller 18, wherein the detection support roller 18 is rotatably mounted on the lifting adjustment plate 16 and is detachably connected to the inner side wall of the eccentric control ring plate 12; An adjustment notch 20, wherein the adjustment notch 20 is provided on the lifting adjustment plate 16, and a movable slide plate 22 is slidably installed in the adjustment notch 20, and a driven pressure roller 23 is rotatably installed at one end of the movable slide plate 22, and the driven pressure roller 23 is detachably connected to the outer side wall of the eccentric control ring plate 12; A telescopic cylinder 17, wherein the telescopic cylinder 17 is fixedly mounted on the lifting and adjusting plate 16; 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 slide 22.

[0042] During the movement of the improved tillage equipment 1, starting the drive motor 3 can drive the rotating shaft 10 to rotate, and drive multiple turning devices 11 to turn the soil. In this process, the improver is spread, which can make the soil and the improver 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. Under the action of the eccentric control ring plate 12's own structure, the eccentric control ring plate 12 will intermittently contact with 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 guide control sleeve 15, and the lifting adjustment plate 16 will drive the lifting connecting rod 28 to move upward, and the lifting connecting rod 28 will drive multiple sliding blocking plates 30 to move upward synchronously and stably in the slide seat 29, wherein the eccentric The number of control ring plates 12 and lifting adjustment plates 16 can be two sets, which are respectively located at the two end positions of the rotating shaft 10, so as to drive the two ends of the lifting connecting rod 28 to move up synchronously, thereby ensuring the smooth sliding of the sliding blocking plate 30. No more details are given here. When the sliding blocking plate 30 moves up and gradually separates from the discharge port 35, the improver gathered in the discharge control bin 27 will flow to the outside through the discharge port 35. In the process of the movement of the sliding blocking plate 30, the elastic lever 36 will be driven to move up synchronously. Under the disturbance of the elastic lever 36, the improver is prevented from being blocked at the discharge port 35, thereby ensuring the smooth discharge of the improver. After the improver enters the inclined material transfer cylinder 31, it finally enters the spray bin 33 through the middle material gap 37, and is discharged to the soil surface that is about to be turned over through multiple injection ports 34, thereby completing the purpose of intermittent discharge. When the conductivity sensor 9 detects a change in the salt content of the soil, the conductivity sensor 9 will control the telescopic cylinder 17 to start, and the telescopic cylinder 17 will push or pull the telescopic rod 19 to move, and the telescopic rod 19 will drive the moving slide plate 22 to slide in the adjustment slot 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, thereby changing the length of time for the sliding sealing plate 30 to separate from the discharge port 35 and the amount of the improver discharged through the discharge port 35, so as to achieve the discharge amount of the improver to be adjusted according to the local need to increase or decrease the improver in the same improved area. The purpose of adaptive adjustment is to detect the time period of rotation of the support roller 18 and the driven pressure roller 23 to determine whether the equipment is operating normally. In addition, the surface of the eccentric control ring plate 12 is provided with anti-collision pads in the form of sponge or the like to avoid large collisions and damage between components. Moreover, when the lifting and adjusting plate 16 slides in the guide control sleeve 15, under the elastic action of the reset spring 24, the lifting and adjusting plate 16 can be restored to its original position during the rotation of the eccentric control ring plate 12. Among them, the sliding mode between the detection connecting block 25 and the guide sliding cavity 26 can adopt the form of damped sliding to avoid shaking or jittering of the lifting and adjusting plate 16 during the lifting process. No further details will be given here.

[0043] In one embodiment of the present invention, see Figure 1-Figure 14 , further comprising: an air pump 32, wherein the number of the air pumps 32 is multiple, and the multiple air pumps 32 are all fixedly mounted on the inclined material transfer cylinder 31, and are respectively connected to the spraying bin 33 through multiple air pipes; The air pump 32 is also electrically connected to the detection connection block 25 .

[0044] 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 blocking plate 30 slides upward, and the discharge port 35 is opened for discharging. Then, the improver will enter the inclined material transfer cylinder 31 and the spray bin 33 under the action of its own gravity. In addition, when the lifting and adjusting plate 16 moves upward, the reset spring 24 will gradually be in a stretched state, and the tension detected by the detection connection block 25 will increase. At this time, the sensor on the detection connection block 25 will control the air pump 32 to stop. On the contrary, when the eccentric control ring plate 12 continues to rotate, the reset spring 24 will gradually be in a stretched state. Under the pulling force of the spring 24, when the lifting and adjusting plate 16 moves downward, the sliding blocking plate 30 will block the discharge port 35 again. At this time, the pulling force detected by the sensor on the detection connection 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 improver that has accumulated in the spray bin 33. Among them, by delaying the start of the air pump 32, on the one hand, sufficient time can be provided for the improver to flow from the inclined material transfer cylinder 31 into the spray bin 33, so that when the improver is almost all accumulated in the spray bin On the other hand, the air can be inflated after the sliding blocking plate 30 completely blocks the discharge port 35 again to avoid the airflow affecting the improver in the discharge control bin 27. In addition, the middle material gap 37 can also prevent the improver in the spray bin 33 from flowing back, which will not be described in detail here (in addition, the detection support roller 18 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 been completely separated from the driven pressure roller 23. At this time, the sliding blocking plate 30 completely discharges the material. The opening 35 is blocked to further ensure the smooth operation of the equipment), then under the action of the airflow, a certain amount of improver, especially when the amount is large, can be evenly spread on the soil surface to ensure that the improver and the soil are fully mixed. Moreover, since the injection 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 up, the improver can be sprayed at high pressure, and the improver can be further mixed into the soil to avoid the improver existing only on the surface of the soil, which is conducive to further improving the effect of soil improvement.

[0045] A method for reducing alkali and improving fertilizer for medium-to-severe salinization cultivated land, using the above-mentioned device for reducing alkali and improving fertilizer for medium-to-severe salinization cultivated land, specifically comprising the following steps: Step 1: The external traction device drives the improved tillage device 1 to move on the ground through the connecting frame 8, and starts the drive motor 3, which drives the rotating shaft 10 and the soil turning device 11 to rotate; 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 wall of the eccentric control ring plate 12 contacts the driven pressure roller 23, the driven pressure roller 23 and the lifting adjustment plate 16 will be pushed to move upward, and the lifting connecting rod 28 and the sliding blocking plate 30 will be driven to move upward synchronously. During the separation of the sliding blocking plate 30 and the discharge port 35, the powdered improver in the discharge control bin 27 enters the inclined transfer cylinder 31 through the opening of the discharge port 35, thereby realizing intermittent discharge. Step 3, the powdered improver entering the inclined transfer cylinder 31 is finally sprayed onto the surface of the soil to be turned through multiple spray ports 34; Step 4.
