Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a paddy field soil crushing and compaction vibratory slurry lifting machine. Background Technology

[0002] Before planting rice seedlings in paddy fields, land preparation is necessary to create a flat, finely broken seedbed with a certain thickness of slurry, providing favorable conditions for subsequent transplanting. Traditional paddy field preparation typically involves several independent steps: first, dry tillage using a rotary tiller to initially break up rice stubble, straw, and topsoil; then, flooding the field to soften the soil; next, using a paddy field slurry leveling machine to create a slurry; and finally, after a long period of natural settling (usually 5-7 days), transplanting is carried out, during which floating straw and other debris are manually removed. These steps often require different machines to be used multiple times, leading to the following problems:

[0003] First, the frequent operations and tractor visits lead to severe soil compaction, damaging the soil's aggregate structure and increasing fuel consumption and operating costs. Second, the paddy field remains submerged for extended periods during flooding and multiple operations, resulting in significant water losses through evaporation and seepage. This is particularly problematic in water-scarce areas, where flooding accounts for over 30% of the total water consumption during the rice growing season, leading to severe water waste. Third, repeated irrigation and drainage cause the loss of applied base fertilizer (especially nitrogen fertilizer), reducing fertilizer utilization and increasing the risk of agricultural non-point source pollution. Fourth, the natural sedimentation process is time-consuming and highly dependent on temperature and soil texture, often delaying planting and impacting rice yield. Fifth, the independent operation of each process can lead to problems such as missed stubble and uneven sedimentation, making it difficult to guarantee the quality of land preparation.

[0004] Furthermore, while some existing combined tillage machines integrate slurry mixing and leveling functions, they lack effective burial of rice stubble and active creation of slurry layers, still relying on natural slurry settling, resulting in unsatisfactory operational effects. Therefore, there is an urgent need for a paddy field tillage machine that can complete soil breaking, stubble compaction, slurry lifting, slurry creation, and leveling operations in one go, while saving water, reducing the number of times the machine needs to be entered, and shortening the farming time. Summary of the Invention

[0038] The vibratory slurry lifting plate is located at the lower end of the hinged movable frame, between and behind the adjacent pressing plates, and the top of the vibratory slurry lifting plate is provided with a flow guiding slope.

[0039] The vibration transmission rod is fixedly connected at one end to the bottom of the hinged movable frame and detachably connected at the other end to the vibrating slurry lifting plate, so as to transmit the eccentric vibration generated by the eccentric vibrating block to the vibrating slurry lifting plate.

[0040] The slurry protrusions are fixedly installed on the lower surface of the vibrating slurry-lifting plate. They are set as cylindrical, pyramidal, or trapezoidal teeth, arranged in a matrix or strip shape, and are used to perform secondary vibration, mixing, and slurry-lifting layering of the mud layer.

[0041] According to the above technical solution, the surface leveling unit includes:

[0042] The elastic slab for the ground surface is fixedly installed at the lower end of the end movable frame by bolts, and is inclined downward in the direction away from the vibrating and slurry lifting unit;

[0049] The suspension frame is bolted to the rear of the end movable frame and consists of a roller frame and height-adjustable telescopic tubes symmetrically arranged on the upper end of the roller frame.

The height-adjustable telescopic tube is equipped with a locking device to adjust and fix the ground clearance of the floating slurry shaping roller.

[0050] According to the above technical solution, the side wall of the pressing plate is provided with evenly distributed non-smooth pits or convex bumps;

[0051] The lower end face of the stubble pressing plate has an arc-shaped longitudinal section that gradually expands in the working direction, and the lower end face is set with shallow serrations, with the tooth tips rounded to avoid cutting the rice stubble.

[0052] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0053] (1) Multiple processes can be completed in one go, resulting in significant overall benefits.

[0054] This device integrates the soil mixing and crushing unit, dynamic stubble pressing unit, vibration slurry raising unit, and surface leveling unit onto the same traction frame. The tractor can complete the entire paddy field preparation process, including soil mixing and crushing, dynamic stubble pressing, vibration slurry raising, slurry layer creation, and surface leveling, in one pass through the field. Compared to traditional paddy field preparation methods (which require multiple operations such as soaking, stirring, stubble pressing, settling, and leveling), this device simultaneously completes stirring and soil breaking with vibration and slurry extraction. It can directly form a slurry layer without prolonged soaking, thus saving more than 60% of surface soaking water. It also avoids the excess soaking water from traditional methods being released before transplanting, and the loss of fertilizer due to multiple soakings, thereby improving fertilizer utilization. The frequency of tractor visits is reduced from 2-3 times to 1 time, significantly reducing soil compaction and fuel consumption, and improving the quality and efficiency of land preparation. By actively creating a slurry layer through the vibration and slurry extraction unit, it replaces the passive process of relying on natural gravity for slurry settling, shortening the settling time from 5-7 days to about 1 day, effectively saving farming time and gaining a valuable window of opportunity for subsequent transplanting.

[0055] (2) Compact structure and high power utilization

[0056] This device integrates the dynamic pressing component and the vibratory slurry lifting unit on the same hinged movable frame, and they share the same set of hydraulic vibration components for drive. Compared with traditional models, this invention adopts a combination of mechanical and hydraulic transmission, which significantly reduces the number of power transmission links and hydraulic components, lowers manufacturing costs and overall machine weight, while ensuring the synchronization of pressing and vibration actions and avoiding timing mismatch problems caused by power separation.

[0057] (3) The order of stubble compaction and vibration should be reasonable to avoid secondary floating of rice stubble.

[0058] Because the stubble pressing plate is fixedly installed on the lower end face of the hinged movable frame and located in front of and below the vibrating slurry-lifting plate, while the vibrating slurry-lifting plate is located between and behind the adjacent stubble pressing plates, during operation, the stubble pressing plate first forces the rice stubble and rice straw down into the mud layer, and then the vibrating slurry-lifting plate performs high-frequency vibration on the same area. This spatial and temporal sequence of "pressing first and then vibrating" ensures that the rice stubble already pressed into the mud will not be turned over again by subsequent vibration, significantly improving the stubble burial rate.

[0059] (4) The vibration frequency of each dynamic pressing component can be adjusted independently.

[0060] The hydraulic vibration assembly consists of multiple independent circulating oil circuits, each corresponding to one of the eccentric vibrating boxes. Each independent oil circuit is equipped with a regulating valve to individually adjust the speed of the corresponding hydraulic motor. Operators can adjust the vibration frequency of each dynamic stubble compaction component according to the differences in stubble density in different areas of the field (e.g., denser in the middle and sparser at the edges) to achieve precise stubble compaction and pulp lifting, avoiding localized under-compaction or over-vibration.

[0061] (5) The stubble depth can be quantitatively adjusted to adapt to different soil conditions.

[0062] The quantitative elastic reset assembly, through the cooperation of a hollow metering cylinder, a telescopic spring, a first square movable plate, a second square movable plate, a double-threaded rod, and a rotary adjustment handle, achieves precise adjustment of the rebound force of the articulated movable frame. Rotating the rotary adjustment handle changes the preload of the telescopic spring, thereby controlling the pressing depth of the stubble plate and adapting to the operational needs of different soil types such as clay, loam, and sandy loam, as well as rice stubble thickness.

[0063] (6) The interlocking board has a biomimetic anti-adhesion and anti-slip structure.

[0064] The sidewalls of the stubble pressing board are decorated with evenly distributed non-smooth pits or bumps, reducing the contact area between the wet mud and the board surface and significantly lowering adhesion resistance. Simultaneously, the lower end face of the stubble pressing board has a gradually expanding arc-shaped cross-section in the working direction, and the lower end face is designed with shallow serrations, with rounded tips. The shallow serrations effectively grip the rice stubble to prevent slippage, the gradually expanding arc design reduces downward pressure resistance, and the rounded tips of the serrations avoid cutting off the rice stubble, ensuring that the rice stubble is completely pressed into the mud.

[0065] (7) The vibratory slurry lifting unit has a variety of slurry protrusion structures, resulting in good slurry lifting effect.

[0066] The protrusions on the lower surface of the vibratory slurry-collecting block can be cylindrical, pyramidal, or trapezoidal, arranged in a matrix or strip pattern. Different shapes of protrusions are suitable for different soil types: pyramidal protrusions have strong crushing ability for clay, while cylindrical protrusions provide good uniformity in sandy loam. Under high-frequency vibration, the protrusions repeatedly penetrate the mud layer, causing the mud to undergo thixotropic liquefaction and breaking up the underlying clay particles, which are then thoroughly mixed with water to form a fine and uniform slurry layer, providing an ideal seedbed for subsequent rice transplanting.

[0067] (8) The surface leveling unit has multi-level leveling and contouring capabilities.

[0068] The flexible screed plate is floatingly mounted on the lower end of the movable end frame via a lifting guide rod, a rear rod, and a return spring. It can move independently up and down according to the terrain undulations to achieve initial leveling. One end of the lifting chain is connected to the movable end of the hinged movable frame, and the other end is connected to the movable end frame. When the screed plate encounters a hard object and rises sharply, the lifting chain will drive the movable end frame and the flexible screed plate to rise, avoiding soil shoveling. In addition, the extension plate can be manually pulled out to increase the screed width, improving adaptability to different field widths.

[0069] (9) Optional floating slurry shaping rollers can be used to achieve fine finishing and thickness setting.

[0070] When a floating slurry shaping roller is configured, it is positioned behind the elastic slurry leveling plate. The guide spiral lines on the outer wall can divert excess slurry to both sides, eliminating the tiny ripples left by the slurry leveling plate. The height adjustment telescopic tube and locking device can precisely adjust the ground clearance of the shaping roller, thereby controlling the final slurry thickness, making the slurry surface smooth and dense, reducing thickness errors, and meeting high-standard rice transplanting requirements.

[0127] A floating slurry shaping roller 57 is set behind the elastic sizing plate 51 on the ground surface, and its outer wall is provided with a guide spiral line for diverting excess slurry.

[0128] The suspension frame 58 is bolted to the rear of the end movable frame 17. It consists of a roller frame 581 and height-adjusting telescopic tubes 582 symmetrically arranged on the upper end of the roller frame 581. The end of the height-adjusting telescopic tube 582 is bolted to the side wall of the end movable frame 17. The floating slurry shaping roller 57 is movably installed inside the roller frame 581. The height-adjusting telescopic tube 582 is provided with a locking element 59 to adjust and fix the ground clearance of the floating slurry shaping roller 57.

[0129] Specifically, the sidewall of the pressing plate 32 is provided with evenly distributed non-smooth pits or bulges;

[0130] The lower end face of the stubble pressing plate 32 has an arc-shaped longitudinal section in the working direction, and the lower end face is set with shallow serrations, with the tooth tips rounded to avoid cutting the rice stubble.

[0131] The paddy field soil crushing and compaction vibratory slurry lifting machine is a suspended paddy field tillage implement. It is connected to the tractor's rear three-point suspension system via a three-point suspension connector 6 at the front end of the tow frame 1. During operation, the tractor's power take-off shaft transmits power to the implement, sequentially completing four continuous operation stages: soil crushing and compaction, dynamic compaction, vibration slurry lifting, and surface leveling. The dynamic compaction unit 3 and the vibration slurry lifting unit 4 share the same hydraulic vibration assembly 7, achieving a compact structure and synchronized operation.

[0132] The workflow is as follows:

[0133] I. Preparations and Power Input Before Operation

[0134] Before operation, connect the three-point suspension connector 6 at the front end of the drawbar 1 to the rear three-point suspension system of the tractor. The tractor's power output shaft is connected to the main power output shaft 13 of the central transmission box 11. After starting the tractor, power is transmitted to the central transmission box 11 via the main power output shaft 13. Inside the central transmission box 11, the power is divided into two paths via gears or chains:

[0135] One path: The transmission is transmitted through the transmission half-shaft 14 to the transmission half-shaft 14 inside the side wing half-shaft tube 12, and then the agitator shaft 24 is driven to rotate by the side transmission gear set 26.

[0136] Another route: the triple gear pump 71 is driven by the auxiliary drive shaft 15 and the sprocket drive assembly 72 to provide pressurized oil to the hydraulic system.

[0137] Meanwhile, the tractor's forward speed is usually controlled at 0.8-1.2 m / s, and the implements complete the soil crushing, stubble pressing, slurry vibrating and leveling operations in sequence.

[0138] II. Formal Work Process

[0139] Step 1: Preliminary action of the grout mixing and soil breaking unit 2

[0140] When the equipment enters the field, the slurry mixing and soil breaking unit 2 first comes into contact with the original ground surface. This unit consists of a mounting frame 21, a protective cover 22, a side plate 23, a stirring cutter shaft 24, a mixing cutter head 25, and a side transmission gear set 26.

[0141] The agitator shaft 24 rotates at high speed (approximately 200-400 rpm) driven by the transmission half-shaft 14. The agitator heads 25 evenly distributed on it cut, strike, and agitate the rice stubble, rice straw, and soil, while forcibly mixing water and soil to form coarse mud.

[0142] The protective cover 22 prevents mud splashing, and the side plate 23 is fixed to the end of the side wing half shaft tube 12, providing the installation base for the protective cover 22 and ensuring consistent mud mixing depth.

[0143] After passing through this unit, large soil particles are broken up, and the rice stubble is initially separated from the soil, providing a uniform material base for subsequent stubble pressing and pulping.

[0144] Step 2: The stubble pressing plate 32 of the dynamic stubble pressing unit 3 presses down the rice stubble at high frequency.

[0145] The coarse mud layer then enters the working area of ​​the dynamic scrambling unit 3. This unit consists of multiple dynamic scrambling components arranged in a linear array along the working direction.

[0146] Each dynamic interleaving component includes:

[0147] Hinged movable frame 31: One end is movably installed at the lower end of the sunken frame 163, and can swing up and down around the hinge point. The movable end is inclined downwards towards the ground surface leveling unit 5. A gap is left between adjacent hinged movable frames 31 to achieve independent contouring.

[0148] The stubble pressing plate 32 is fixedly installed on the lower end face of the hinged movable frame 31 and arranged in a linear array along the length of the hinged movable frame 31. The side wall of the stubble pressing plate 32 is provided with evenly distributed non-smooth pits or bumps to reduce mud adhesion; its lower end face has an arc-shaped gradually expanding longitudinal section in the working direction, and the lower end face is set with shallow serrations with rounded transitions at the tooth tips to prevent cutting the rice stubble.

[0149] Quantitative elastic reset component 33: It is mirror-symmetrically arranged on the hinged movable frame 31, with its upper end connected to the lower end of the tail wing fixing frame 16 and its lower end connected to the movable end of the hinged movable frame 31, providing adjustable rebound force for the pressing plate 32.

[0150] Driven by the hydraulic vibration assembly 7, the stubble pressing plate 32 experiences high-frequency vertical vibration. As the tractor moves forward, the inclined stubble pressing plate 32 forces the rice stubble and straw floating on the mud surface into the lower layer of the mud. The shallow serrated lower end face can hold the rice stubble in place, preventing it from slipping; the arc-shaped gradually expanding design reduces downward pressure resistance. When the ground is uneven or encounters hard objects, the hinged movable frame 31 can overcome the spring force in the quantitative elastic reset assembly 33 and float upward, avoiding damage.

[0151] Step 3: Vibration and slurry raising unit 4 simultaneously vibrates and raises slurry in the same area.

[0152] The vibratory slurry lifting unit 4 is integrated and installed on each dynamic pressing component in a corresponding manner, and is driven and connected to the same hydraulic vibration component 7.

[0153] Each vibratory slurry extraction unit 4 includes:

[0154] Vibratory slurry lifting plate 41: Located at the lower end of the hinged movable frame 31, between and behind the adjacent pressing plate 32. The top of the vibratory slurry lifting plate 41 is provided with a flow guiding slope 411.

[0155] Vibration transmission rod 42: One end is fixedly connected to the bottom of the hinged movable frame 31, and the other end is detachably connected to the vibrating slurry lifting plate 41.

[0156] Slurry protrusions 43: fixedly installed on the lower surface of the vibratory slurry lifting plate 41, and set as cylindrical, pyramidal or trapezoidal teeth, arranged in a matrix or strip.

[0157] Since the slab pressing plate 32 and the vibrating slurry lifting plate 41 are installed on the same hinged movable frame 31 and share the same vibration source, their vibrations are completely synchronized.

[0158] The specific vibration source comes from hydraulic vibration component 7:

[0159] The triple gear pump 71 is driven by the auxiliary drive shaft 15 through the sprocket drive assembly 72, and draws in hydraulic oil from the hydraulic oil tank 73 and pressurizes it.

[0160] The pressurized oil is delivered to the hydraulic motor 75 outside the eccentric vibrating box 74, which corresponds one-to-one with the hinged movable frame 31, via the independent circulation oil circuit 78 (each independent oil circuit is equipped with a regulating valve).

[0161] The hydraulic motor 75 drives the eccentric vibrating shaft 76 and the eccentric vibrating block 77 to rotate at high speed, generating high-frequency eccentric vibration. This vibration is transmitted to the hinged movable frame 31 via the eccentric vibrating box 74, and then rigidly transmitted to the vibrating slurry lifting plate 41 via the vibration transmission rod 42.

[0162] The independent circulating oil circuit 78 allows the speed of each hydraulic motor 75 to be adjusted individually via the regulating valve, thereby independently controlling the vibration frequency of each dynamic stubble assembly to adapt to the differences in stubble density in different areas of the field (such as the middle and the edge).

[0163] Under vibration, the slurry protrusions 43 on the lower surface of the vibrating slurry-lifting plate 41 are frequently inserted into the mud layer, producing the following effects:

[0164] High-frequency vibration induces a "thixotropic liquefaction" effect in the mud, temporarily reducing its viscosity and facilitating the suspension of fine particles. "Thixotropic liquefaction" refers to the reversible phenomenon where, under periodic shearing or vibration, the internal network structure of certain high-concentration suspension systems (such as clay-water mixtures) is disrupted, causing the system to transform from a solid-like state (high viscosity, yield stress) to a liquid-like state (low viscosity, easy flow). In this device, the mud-forming protrusions on the lower surface of the vibrating mud-lifting plate generate high-frequency (typically 20-35 Hz), small-amplitude (2-5 mm) vertical vibrations driven by the hydraulic vibration assembly.

[0165] Driven by a hydraulic vibration assembly, the mud-forming protrusions impact the still-softened hard clay clods or soil at high frequency. The tips (pyramidal or trapezoidal teeth) of the protrusions generate extremely high local stress (up to several megapascals), causing the soil clods to fracture along micro-cracks. The protrusions reciprocate rapidly in the mud, generating strong eddies and jets locally, driving the mud to flow at high speed through the gaps between the protrusions, achieving convective mixing. Under natural static conditions, the mud is prone to stratification, with coarse particles settling and fine particles floating. The high-frequency agitation of the mud-forming protrusions continuously disrupts this stratification, stirring the thicker mud at the bottom to the top, while simultaneously introducing water from the top to the bottom, thus ensuring a uniform overall mud concentration.

[0166] The guide slope 411 directs the mud to flow backward and upward, preventing accumulation.

[0167] Since the stubble pressing plate 32 has already pressed the rice stubble into the lower layer, the slurry-lifting protrusion mainly acts on the pure mud-clay mixture system, avoiding the rice stubble from entangled in the protrusion. At the same time, the high-frequency vibration of the protrusion and the vibration of the stubble pressing plate come from the same hydraulic vibration component. The two have the same frequency and phase, ensuring the synchronicity of the stubble pressing and slurry lifting actions, and avoiding energy cancellation or slurry layer disorder caused by asynchronous vibration.

[0168] Step 4: The surface leveling unit 5 performs final leveling and shaping.

[0169] The vibrated slurry layer finally reaches the surface leveling unit 5. This unit is movably installed at the rear end of the traction frame 1, located behind the vibrating slurry lifting unit 4, and includes:

[0170] The surface elastic leveling plate 51 is fixed to the lower end of the end movable frame 17 by bolts and is set inclined downwards in the direction away from the vibrating and slurry lifting unit 4.

[0171] Lifting guide rod 52: It is mirror-symmetrically set on the upper end of the ground elastic plate 51. The bottom of the lifting guide rod is movably installed on the top of the ground elastic plate 51, and the top of the lifting guide rod is movably installed through the rear rod 53 on the side wall of the end movable frame 17.

[0172] Return spring 54: It is movably sleeved on the lifting guide rod 52, and its upper end abuts against the lower end of the rear rod 53, so that the elastic flat plate 51 of the ground surface can float up and down with the terrain.

[0173] Outer extension plate 55: Movably installed on the side wall of the elastic leveling plate 51 on the ground surface, and can be manually flipped to increase the leveling length.

[0174] Lifting chain 56: One end is fixedly installed on the movable end of the hinged movable frame 31, and the other end is fixedly connected to the end movable frame 17. When the hinged movable frame 31 is lifted significantly due to encountering great resistance, the lifting chain 56 will lift the end movable frame 17, causing the surface leveling unit 5 to be slightly lifted, thus avoiding soil shoveling.

[0175] The surface elastic leveling plate 51 initially smooths the surface of the vibrated slurry layer and pushes the excess slurry forward or to the side to form a basically flat slurry surface.

[0176] The floating slurry shaping roller 57 can be used as an optional component. If the machine is equipped with the floating slurry shaping roller 57, the surface leveling unit 5 also includes:

[0177] Floating slurry shaping roller 57: Located behind the elastic sizing plate 51 on the ground surface, with a guide spiral line on the outer wall for diverting excess slurry.

[0178] The suspension frame 58 is bolted to the rear of the end movable frame 17 and consists of a roller frame 581 and height-adjustable telescopic tubes 582 symmetrically arranged on the upper end of the roller frame 581. The end of the height-adjustable telescopic tube 582 is bolted to the side wall of the end movable frame 17. The floating slurry shaping roller 57 is movably installed inside the roller frame 581. The height-adjustable telescopic tube 582 is equipped with a locking element 59 to adjust and fix the ground clearance of the floating slurry shaping roller 57.

[0179] During operation, the floating slurry shaping roller 57 rolls under its own weight and forward resistance. The guide spiral lines on its surface guide excess slurry to both sides, while eliminating the tiny ripples left by the elastic slab 51 on the ground surface, and lightly compacting and fixing the thickness of the slurry surface. The final slurry thickness can be precisely controlled by adjusting the height adjustment telescopic tube 582 and fixing it with the locking device 59.

[0180] It is important to note that throughout the entire workflow, the stubble pressing plate 32 and the vibrating slurry-lifting plate 41 are installed on the same hinged movable frame 31 and share the same eccentric vibration source. Their vibration frequencies and phases are completely synchronized, and the longitudinal distance is fixed. This ensures a seamless transition between pressing and vibration: the stubble pressing plate 32 first presses the rice stubble into the mud, and then (approximately 0.1 seconds later) the vibrating slurry-lifting plate 41 lifts the slurry from the same area, preventing the rice stubble from being turned over again. Simultaneously, the regulating valves on the independent circulating oil circuit 78 can adjust the speed of each hydraulic motor 75, thereby independently controlling the vibration frequency of each dynamic stubble pressing component to adapt to differences in rice stubble density in different areas of the field (e.g., denser in the middle and sparser at the edges).

[0181] The side transmission gear set 26, the bevel transmission gear set 339, and the sprocket transmission set 72 involved in this device are all conventional mechanical transmission methods for realizing power steering, speed change, or transmission within the technical field. Their specific structures, tooth profile parameters, installation, and lubrication methods are all content that can be conventionally selected or designed by those skilled in the art based on the transmission ratio and installation space. Therefore, no further structural details will be provided in this specification.
