[0002] In rice production, "soil soaking" is an important step, which refers to the process of soaking the paddy fields with irrigation water. Before soaking the fields, the soil needs to be turned over and prepared. A Chinese patent discloses a soil turning and fertilization device with adaptive adjustment based on the size of the experimental field, application number 202410668746.3. This device can adjust the distance between multiple rotary tillage blades to adjust the density of soil turning and the walking width of soil turning, which improves the balance of soil turning operation in a general direction.

[0003] However, current soil turning equipment is not compatible with the speed of movement and turning, which can easily cause large fluctuations in the unit turning rate during the turning process. This can lead to significant deviations in the degree of turning in certain areas, resulting in poor balance in the turning operation and uneven soil settlement after flooding. In addition, there are few external traction mechanisms available, making it difficult to flexibly adapt to different terrain and environmental requirements, and the reliability of the turning operation is poor.

[0022] Compared with the prior art, the advantages of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use;

[0023] 1. Equipped with a synchronous gripping mechanism, a preliminary hydraulic amplification mechanism can be constructed through the cooperation of a hydraulic box, sliding shaft, base plate, guide pipe, push shaft, and side plate. This mechanism synchronously amplifies and converts the driving force. Combined with the transmission conversion effect of the ball head, lever, and support head, a secondary synchronous amplification mechanism for external traction force can be constructed. This effectively transforms external traction force into the rotational power of the rotary tiller blades, significantly improving the compatibility and adaptability between tillage speed and frame travel speed. On the one hand, it effectively improves the controllability of the unit tillage rate, making the soil looseness more uniform after tillage, and the clod size more uniform. This greatly enhances the quality of tillage and makes subsequent flooding operations more convenient and stable, indirectly improving the efficiency and effectiveness of flooding operations. On the other hand, it makes tillage actions more timely and effective, effectively avoiding local tillage omissions caused by fluctuations in frame travel speed, significantly reducing tillage blank areas, and making tillage operations more reliable and effective.

[0024] 2. By cooperating with the rack sleeve, gear shaft, speed-changing wheel, drive wheel, and transmission belt, a speed-changing amplification structure can be constructed. Combined with a two-stage synchronous amplification mechanism for external traction force, the speed and force of the external traction force can be double-amplified. Furthermore, the limiting transmission functions of the actuating wheel, gear seat, one-way gear disc, gear column, cutter shaft, polygonal shaft, bevel gear, gear sleeve, and gear belt significantly improve the transmission stability and reliability of the external traction force. On the one hand, this allows for more timely and effective conversion of driving force, ensuring sufficient stability of the driving force, improving the stability and efficiency of the rotary tiller's gripping action, enhancing the land tillage effect, and making tillage operations more balanced and stable. On the other hand, it effectively reduces load pressure, significantly reduces energy consumption, and indirectly improves the energy efficiency and environmental friendliness of the equipment. Simultaneously, the reduced load pressure increases the selectivity of the external traction mechanism, allowing it to handle more complex terrains, making tillage operations more flexible, efficient, and reliable, and expanding its application range.

[0025] 3. Equipped with a dynamic control mechanism, this device, through the combination of a box, bottom cylinder, pressurization chamber, connecting pipe, air vent, and adjustment chamber, can construct a dual-limit transmission space for both air and hydraulic fluid. This allows for the conversion of hydraulic fluid into air, significantly improving the stability and smoothness of tillage depth adjustment. Combined with the transmission conversion effects of strips, piston plates, connecting rods, sliding rods, mounting plates, probes, mounting ears, power rods, and sliding plugs, it can construct a dynamic tillage depth adjustment structure. On one hand, it can synchronously and dynamically control the tillage depth during land tillage operations, greatly reducing fluctuations in tillage depth and making the tillage depth more balanced and stable, thus greatly improving the tillage effect. This allows subsequent paddy field soaking operations to achieve a more efficient and stable water-reaching state, improving the convenience and uniformity of paddy field soaking operations. On the other hand, it can be used in conjunction with rotary tillage blades to achieve dual tillage and land improvement, greatly enhancing the uniformity and reliability of tillage and improving the tillage effect.

[0026] 4. By combining the receiving cavity, infusion pipe, long stopper plate, and screw, a hydraulic fluid adjustment and compensation structure can be constructed. On the one hand, it can be used in conjunction with the scale rod and graduation lines to flexibly limit and adjust the standard tillage depth, allowing the equipment to meet more tillage depth requirements, effectively improving the equipment's adaptability and expanding its effective range of application, making tillage operations more flexible and efficient. On the other hand, it can perform convenient zeroing calibration of the equipment, dynamically compensating for wear dimensional errors of the rotary tiller blades. This not only effectively improves tillage accuracy and makes tillage operations more stable and reliable, but also allows the rotary tiller blades to perform tillage operations more continuously and stably, extending the effective service life of the rotary tiller blades and indirectly enhancing the effective service life of the equipment. Through the coordination of the alignment rod, mounting rod, rubber head, limit frame, switch, and indicator light, synchronous early warning detection of tillage depth fluctuations can be performed, effectively improving the timeliness and effectiveness of equipment calibration and adjustment, reducing the impact range of tillage depth fluctuations, and further ensuring the stability of tillage operations.

[0027] In summary, this soil turning equipment for paddy field remediation can amplify both the speed and force of external traction, increasing the selectivity of the external traction mechanism and making the equipment more flexible in use. At the same time, it can significantly enhance the controllability of the unit turning rate, improve the uniformity and effectiveness of the turning operation, and dynamically control and provide fluctuation warnings for the turning depth, greatly improving the stability of the turning operation and simultaneously improving the turning efficiency and quality.

An indicator light 325 is installed in the middle of the top of the limit frame 323. The thickness of the rubber head 322 is three centimeters different from the length of the limit frame 323. The switch 324 is the control switch for the indicator light 325. The input terminals of the switch 324 and the indicator light 325 are electrically connected to the output terminal of an external power supply to enable real-time detection and limitation of the tillage depth, improve the timeliness and effectiveness of equipment calibration and maintenance during tillage, and enhance the tillage quality.

[0058] The working principle and usage process of this invention: When this soil turning and tilling equipment for paddy field improvement is actually used, firstly, the screw 318 is rotated to drive the long stopper plate 317 to press down, and the hydraulic fluid inside the receiving cavity 315 is pressed into the bottom cylinder 302 through the infusion pipe 316. Under the connection of the connecting pipe 319, the hydraulic fluid will enter the regulating cavity 312 simultaneously, and simultaneously squeeze the piston plate 305 and the sliding plug 313, forcing the probe 309 and the rotary tiller 221 to rise synchronously under the hydraulic action, so that the probe 309 and the rotary tiller 221 are lifted off the ground. Then, the frame 100 is connected to the external traction mechanism through the hanging ear 101, and the frame 100 is dragged to the paddy field to be improved. The external traction mechanism mentioned here and below is not limited to agricultural machinery. Under special conditions, it can even be dragged by manpower or livestock.

[0059] After the frame 100 is delivered to the paddy field to be rectified, the screw 318 is rotated in the reverse direction to drive the long stopper plate 317 to rise. The hydraulic fluid inside the bottom cylinder 302 is drawn into the receiving cavity 315 through the infusion pipe 316. Under the connection of the connecting pipe 319, the hydraulic fluid inside the regulating cavity 312 is also drawn into the receiving cavity 315 at the same time. After losing the support of the hydraulic fluid, the probe 309 and the rotary tiller 221 will descend synchronously under the action of gravity. After the probe 309 and the rotary tiller 221 contact the paddy field ground, they will no longer descend due to the support of the ground. The scale line 3182 on the scale rod 3181 at this time is the zero scale.

[0060] Continue to rotate the screw 318 in the opposite direction and adjust the rising height of the long plug plate 317 according to the actual tillage depth. From the force-bearing area relationship of the piston plate 305, the sliding plug 313 and the long plug plate 317, as well as the weight borne by the piston plate 305 and the sliding plug 313, it can be seen that the rising height of the long plug plate 317 is the same as the falling height of the hydraulic fluid inside the bottom cylinder 302 and the adjustment chamber 312. According to the scale line 3182 on the scale rod 3181, adjust the rising height of the long plug plate 317 relative to the zero scale. This relative rising height is the depth that the probe 309 and the rotary tiller 221 can press down during tillage, that is, the tillage depth. Then, air is injected into the pressurization chamber 303 through the air valve 3031. With the air guide hole 320 open, the air will enter the adjustment chamber 312 simultaneously to press the sliding plug 313. Here, the air pressure on the top of the sliding plug 313 should be greater than the weight it bears.

[0061] After the above adjustments are completed, the frame 100 can be dragged by the external traction mechanism to carry out the paddy field plowing and rectification operation. As the ground wheel 103 rotates, the drive wheel 207 will rotate synchronously under the drive of the wheel axle 102. Then, under the transmission action of the transmission belt 208, the gear wheel 206 will drive the gear shaft 205 to rotate synchronously, forcing the rack sleeve 204 to drive the base plate 203 to move up and down synchronously through the sliding shaft 202.

[0062] During the rising process of the base plate 203, the hydraulic fluid inside the vertical cavity 2011 will be pressed into the horizontal cavity 2012 through the through groove 2013 to squeeze the side plate 211. The hydraulic fluid inside the horizontal cavity 2012 located on the other side of the side plate 211 will flow into the vertical cavity 2011 through the guide pipe 209 to replenish the hydraulic fluid at the bottom of the base plate 203. During the falling process of the base plate 203, the hydraulic fluid inside the vertical cavity 2011 will be pressed into the horizontal cavity 2012 through the guide pipe 209 to squeeze the side plate 211. The hydraulic fluid inside the horizontal cavity 2012 located on the side of the through groove 2013 will flow into the vertical cavity 2011 through the through groove 2013 to replenish the hydraulic fluid at the top of the base plate 203.

[0063] Through the above process, the hydraulic fluid can be reciprocated and directionally flowed. During the flow, the pressure at the sliding shaft 202 is initially amplified, forcing the side plate 211 to drive the push shaft 210 to move back and forth with greater force. Under the transmission action of the ball head seat 212, the lever 213 is forced to reciprocate around the support head 214. During the deflection of the lever 213, the pressure is amplified in the second stage, forcing the actuating wheel 215 to actuate the gear seat 216 under the amplified pressure, causing the gear seat 216 to reciprocate.

[0064] Under the limiting action of the slot 2161 and the elastic protrusion 2171, as the tooth seat 216 deflects, the one-way toothed disk 217 will only drive the tooth column 218 to deflect in one direction. Then, under the drive of the toothed sleeve 224 and the toothed belt 225, the polygonal shaft 222 will drive the bevel gear 223 to deflect synchronously, forcing the cutter shaft 220 to drive the rotary tiller 221 to deflect synchronously at a faster speed with greater force under the drive of the bevel gear 223, to turn the soil in the paddy field, improve the synchronicity of the gripping action, and improve the balance and stability of the unit turning rate while ensuring sufficient driving force.

[0065] As the rotary tiller 221 cuts into the paddy field to turn the soil, the soil becomes soft. The supporting force on the rotary tiller 221 and the probe 309 is insufficient to overcome the air pressure on the top of the strip 304 and the sliding plug 313. Under the action of air pressure, the sliding plug 313 drives the mounting ear 310 to press down synchronously through the power rod 311. This forces the cutter shaft 220 to drive each rotary tiller 221 to press down synchronously to turn the paddy field soil under the drag of the transmission box 219 until the sliding plug 313 contacts the bottom hydraulic fluid. Under the limiting action of the hydraulic fluid, it stops pressing down. At this time, the turning depth of the rotary tiller 221 reaches the set value. Here, because the weight and pressure borne by the sliding plug 313 are less than the weight and pressure borne by the piston plate 305, it cannot pump the hydraulic fluid into the bottom cylinder 302, which can ensure the controllability of the turning depth.

[0066] At the same time, the strip plate 304 will drive the piston plate 305 to press down through the connecting rod 306 under the action of air pressure, forcing the mounting plate 308 to drag each probe 309 down under the action of the sliding rod 307, so that the probe 309 cuts into the soil tilled by the rotary tiller 221. During this process, if the rotary tiller 221 does not till the soil to a sufficient depth due to external interference factors, the probe 309 will contact the hard soil at the bottom first. It will stop pressing down under the support of the soil at the bottom. At this time, the hydraulic fluid at the bottom of the piston plate 305 is not enough to overcome the weight and pressure borne by the sliding plug 313 because the top is not supported by the piston plate 305. Under the action of the weight and pressure borne by the sliding plug 313, the hydraulic fluid inside the regulating chamber 312 will be pressed into the bottom cylinder 302 through the connecting pipe 319, so that the rotary tiller 221 can be pressed down again, increasing the tillage depth. At this time, as the frame 100 moves, the probe 309 will also descend synchronously until its bottom is flush with the bottom of the rotary tiller 221.

[0067] Similarly, if the rotary tiller 221 tills to an excessive depth, the piston plate 305 will contact the hydraulic fluid at its bottom first. At this time, since the probe 309 is still in the soft soil and has not contacted the hard soil at the bottom, and the weight and pressure borne by the sliding plug 313 are less than the weight and pressure borne by the piston plate 305, the probe 309 will continue to descend. Under the weight and pressure borne by the piston plate 305, the hydraulic fluid inside the bottom cylinder 302 will be forced into the regulating chamber 312 through the connecting pipe 319, forcing the sliding plug 313 to rise under hydraulic action, thereby forcing the rotary tiller 221 to rise synchronously, reducing the tillage depth. At this time, as the frame 100 moves, the probe 309 will also rise synchronously until its bottom is flush with the bottom of the rotary tiller 221.

[0068] Through the above process, on the one hand, the synchronous dynamic control of the tillage depth can be achieved to ensure the uniformity of the tillage depth. On the other hand, the probe 309 can be used to perform secondary tillage on the paddy field to enhance the tillage effect. During the lifting and lowering of the piston plate 305, the lower plate 304 will drive the limit frame 323 to lift and lower synchronously through the mounting rod 321 via the connecting rod 306. During the lifting and lowering of the sliding plug 313, the rubber head 322 will drive the switch 324 to lift and lower synchronously under the action of the alignment rod 314, so that the switch 324 and the limit frame 323 will have relative displacement. When it is pressed by the limit frame 323, it indicates that the relative displacement distance exceeds the standard value, that is, the difference between the front and back tillage depths exceeds the standard value. The switch 324 will control the indicator light 325 to flash, reminding the staff that the tillage depth fluctuates too much at this time and needs to be calibrated and adjusted in time.
