Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to an integrated machine for tilling and preparing soil in paddy fields. Background Technology

[0002] In the field of agricultural planting, rice is an important food crop, and the quality of field management during its cultivation directly affects its yield and quality. Tilling, soil preparation, and fertilization in paddy fields are key aspects of field management, profoundly impacting soil physical properties, nutrient supply, and the growth and development of rice roots.

[0003] Currently, the soil turning and leveling operations in paddy fields usually only involve simple turning, breaking up, and leveling of the soil. Often, only the soil surface is simply leveled, and the water in the paddy field still seeps into the soil naturally. This makes it difficult to effectively promote the full penetration of water into the soil and to create sufficient pressure to push the water into the deeper soil layers. As a result, the soil moisture content is unevenly distributed, the soil leveling is not good, and the growth environment of rice roots is affected.

[0004] We need to design an integrated machine for tilling and preparing soil in agricultural paddy fields. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated machine for tilling and preparing soil in paddy fields for agricultural use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An integrated machine for tilling and preparing soil in agricultural paddy fields, including a frame, and also including: A walking assembly, mounted on the frame, is capable of intermittent walking and stopping; A soil-turning component is located inside the frame. The soil-turning component is connected to the walking component. When the walking component moves, it drives the soil-turning component to rotate and turn the soil in the paddy field. A soil-forming frame is located at the rear of the machine frame. The soil-forming frame is fixedly connected to the machine frame by two fixing frames. An installation frame is fixed to the top of the soil-forming frame. Channels are provided on both the front and rear walls of the soil-forming frame. The soil-conditioning component is located inside the mounting frame. When the walking component stops, it drives the soil-conditioning component to rotate. The soil-conditioning component and the soil-conditioning frame work together to condition the soil in the plowed paddy field.

[0007] As a further improvement of the present invention, the walking assembly includes a second rotating shaft, which is horizontally mounted on the frame and rotatably connected to the frame. Both ends of the second rotating shaft are fixed with walking wheels. A gear is fixedly sleeved on the side wall of the second rotating shaft. A turntable is provided above the gear. An incomplete gear ring that mates with the gear is fixed on the surface of the turntable. A notch is provided on the side wall of the incomplete gear ring. An extrusion block located at the notch is fixed on the side wall of the turntable. A pressure switch that mates with the extrusion block is provided below the turntable. A first protective shell is fixed on the side wall of the frame. The gear, turntable, incomplete gear ring, extrusion block, and pressure switch are all located inside the first protective shell.

[0008] As a further improvement of the present invention, the soil turning assembly includes a first rotating shaft disposed inside the frame, the first rotating shaft horizontally passing through the frame and rotatably connected to the frame, soil turning blades arranged and fitted on the side wall of the first rotating shaft and located inside the frame, a first synchronous pulley fixedly sleeved on the first rotating shaft, a second synchronous pulley fixedly sleeved on the second rotating shaft, the second synchronous pulley and the first synchronous pulley being connected by a synchronous belt, and a second protective shell fixed on the side wall of the frame, the first synchronous pulley, the second synchronous pulley and the synchronous belt being located inside the second protective shell.

[0009] As a further improvement of the present invention, the soil-settling assembly includes a first piston cylinder and a second piston cylinder disposed inside the mounting frame. The first piston cylinder is fixed to the inner top wall of the mounting frame, and the second piston cylinder is fixed to the top of the soil-settling frame. A vent pipe is connected to the bottom of the second piston cylinder, the vent pipe passing through the soil-settling frame and communicating with the inner side of the soil-settling frame. A first piston plate and a second piston plate are respectively disposed inside the first piston cylinder and the second piston cylinder. A movable rod is disposed between the first piston cylinder and the second piston cylinder, the two ends of the movable rod passing through the first piston cylinder and the second piston cylinder respectively, and the movable rod... Both ends are fixedly connected to the first piston plate and the second piston plate, respectively. A movable plate is sleeved on the outer side of the movable rod. A magnetic suction plate located inside the movable plate is fixedly sleeved on the side wall of the movable rod. A coil spring is connected between the magnetic suction plate and the movable plate. Two electric telescopic rods are installed on the inner top wall of the mounting frame. The telescopic ends of the two electric telescopic rods are fixed to the upper end of the movable plate. Both electric telescopic rods are electrically connected to a pressure switch. When the pressure block presses and triggers the pressure switch, the electric telescopic rod is extended by controlling the pressure switch. When the pressure switch is not triggered, the electric telescopic rod is in the retracted state.

[0010] As a further improvement of the present invention, the top of the frame is provided with a power supply module, a motor, and a reducer. The input end of the reducer is fixedly connected to the output shaft of the motor, and the output end of the reducer is fixedly connected to the turntable.

[0011] As a further improvement of the present invention, it also includes a fertilizer supply assembly located at the top of the frame and a fertilizer application assembly located inside the soil-forming frame. The fertilizer supply assembly includes a storage box located at the top of the frame. The storage box stores liquid fertilizer. A delivery pipe is connected to the side wall of the storage box. The end of the delivery pipe away from the storage box is connected to the side wall of the first piston cylinder. A one-way valve is provided inside the delivery pipe. The fertilization assembly includes a distribution pipe fixed to the top wall of the soil-forming frame. An output pipe is connected to the upper side wall of the distribution pipe. The end of the output pipe away from the distribution pipe passes through the soil-forming frame and is connected to the side wall of the first piston cylinder. A one-way valve is provided inside the output pipe. A main discharge pipe is connected to the lower side wall of the distribution pipe. Evenly arranged branch discharge pipes are connected to the side wall of the main discharge pipe. A discharge nozzle is provided on the upper surface of the branch discharge pipe.

[0012] As a further improvement of the present invention, it also includes two sealing components, which are respectively disposed on the front and rear walls of the soil-forming frame. Each sealing component includes two guide strips fixedly connected to the side wall of the soil-forming frame. The two guide strips are respectively disposed on both sides of the channel. The same sealing plate is slidably inserted into the inner side of the two guide strips. A connecting plate is fixed to the upper side wall of the sealing plate. The connecting plate passes through the side wall of the mounting frame and is fixedly connected to the movable plate. A sliding groove that mates with the connecting plate is provided through the side wall of the mounting frame. The connecting plate is slidably connected to the inner side of the sliding groove.

[0013] As a further improvement of the present invention, two handrails are fixed on the rear side wall of the frame.

[0014] As a further improvement of the present invention, a leveling slope is provided on the rear inner wall of the soil leveling frame.

[0015] The beneficial effects of this invention are: The traveling wheels only rotate when the gears are in complete engagement with the gear ring, and stop moving when there is a gap. This allows the machine to precisely control the rhythm of turning, leveling, and fertilizing, avoiding continuous movement that could affect the quality of the work and improving work efficiency.

[0016] When the walking wheels rotate, the first shaft synchronously drives the soil-turning blade to rotate, realizing the synchronous operation of walking and soil turning. This ensures that the soil turning operation and mechanical movement are strictly matched, avoiding power loss caused by independent driving, while simplifying the transmission structure and improving reliability.

[0017] When the pressure switch is triggered, the electric telescopic rod extends, causing the movable rod to move downward. The second piston plate presses air into the soil-conditioning frame to create positive pressure, forcing water to penetrate the lower soil layer more fully and increasing soil moisture content. Meanwhile, the first piston plate moves downward to draw in liquid fertilizer, achieving coordinated control of water pressure and fertilizer supply, and improving the overall effect of soil conditioning and fertilization in paddy fields.

[0018] As the movable rod moves upward, the first piston plate presses the liquid fertilizer in the first piston cylinder into the distribution pipe through the output pipe, and then sprays it evenly from multiple discharge nozzles through the main discharge pipe and the branch discharge pipe, so that the fertilizer directly enters the soil after soil preparation, avoiding the loss problem caused by surface fertilization. Compared with the traditional surface fertilization method, it is more conducive to the absorption of rice roots. At the same time, the fertilization process is carried out continuously with the soil turning and soil preparation operations, improving the fertilizer utilization rate and operation efficiency of rice planting.

[0019] The sealing assembly moves the sealing plate up and down via the connecting plate. During soil leveling operations, the sealing plate is inserted into the soil sealing channel to prevent positive pressure air in the soil leveling frame from leaking out of the channel, ensuring that water can be pressed into the deep soil more efficiently and enhancing the soil leveling effect. At the same time, the sealing plate moves upward during non-soil leveling operations without affecting the normal movement of the machinery, improving the flexibility and accuracy of the operation.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] See Figures 1-8 An integrated machine for tilling and preparing soil in agricultural paddy fields, comprising a frame 1, and further comprising: The traveling component 3, mounted on the frame 1, is capable of intermittent traveling and stopping. The traveling component 3 includes a second rotating shaft 307, which is horizontally mounted through the frame 1 and rotatably connected to it. Traveling wheels 301 are fixed to both ends of the second rotating shaft 307. A gear 302 is fixedly sleeved on the side wall of the second rotating shaft 307. A turntable 303 is located above the gear 302. An incomplete gear ring 304 that meshes with the gear 302 is fixed on the surface of the turntable 303. The side wall of the incomplete gear ring 304 has a notch. When the incomplete gear ring 304... When the full gear ring 304 meshes with the gear 302, it can drive the gear 302 to rotate through the incomplete gear ring 304. When the gear 302 rotates, it can drive the second rotating shaft 307 to rotate, and drive the traveling wheel 301 to rotate through the second rotating shaft 307, thereby realizing the movement of the frame 1. However, since the incomplete gear ring 304 has a notch, when the incomplete gear ring 304 does not mesh with the gear 302, the incomplete gear ring 304 will not drive the gear 302. At this time, the second rotating shaft 307 and the traveling wheel 301 will not rotate, thereby enabling the intermittent movement of the traveling wheel 301. See Figure 3An extrusion block 305 is fixed on the side wall of the turntable 303 at the notch position. The length of the extrusion block 305 only covers half the length of the notch of the incomplete gear ring 304. When the notch position of the incomplete gear ring 304 rotates to correspond with the gear 302, the electric telescopic rod 706 will first extend and then retract. This ensures that the walking wheel 301 can complete the soil preparation and fertilization operations even when it is stopped. A pressure switch 306 that cooperates with the extrusion block 305 is provided below the turntable 303. A first protective shell 15 is fixed on the side wall of the frame 1. The gear 302, turntable 303, incomplete gear ring 304, extrusion block 305, and pressure switch 306 are all located inside the first protective shell 15. The pressure switch 306 is fixedly installed on the inner wall of the first protective shell 15, which serves as a protective measure.

[0024] The top of the frame 1 is equipped with a power supply module 12, a motor 13, and a reducer 14. The power supply module 12 can be a storage battery to supply power to the various electrical components of the machine. The input end of the reducer 14 is fixedly connected to the output shaft of the motor 13, and the output end of the reducer 14 is fixedly connected to the turntable 303. By starting the motor 13, the reducer 14 transmits power to the turntable 303, thereby driving the walking component 3.

[0025] Two handrails 9 are fixed on the rear side wall of the frame 1, and the frame 1 can be pushed through the two handrails 9.

[0026] See Figure 1 , Figure 2 The soil-turning component 2 is located inside the frame 1 and is connected to the walking component 3. When the walking component 3 moves, it drives the soil-turning component 2 to turn the soil in the paddy field. The soil-turning component 2 includes a first rotating shaft 201 located inside the frame 1. The first rotating shaft 201 horizontally passes through the frame 1 and is rotatably connected to the frame 1. Soil-turning blades 202 located inside the frame 1 are arranged and fitted on the side wall of the first rotating shaft 201. A first synchronous wheel 203 is fixedly sleeved on the first rotating shaft 201. A second synchronous wheel 205 is fixedly sleeved on the second rotating shaft 307. The second synchronous wheel 205 is connected to the first synchronous wheel 203 through a synchronous belt 204. A second protective shell 16 is fixed on the side wall of the frame 1. The first synchronous wheel 203, the second synchronous wheel 205, and the synchronous belt 204 are all located inside the second protective shell 16, which serves as a protective function.

[0027] The soil-conditioning frame 8 is located at the rear of the machine frame 1. The soil-conditioning frame 8 is fixedly connected to the machine frame 1 by two fixed frames 11. The top of the soil-conditioning frame 8 is fixed with an installation frame 10. The front and rear walls of the soil-conditioning frame 8 are provided with channels 17. When the soil-conditioning frame 8 moves in the paddy field, the soil can pass through the channels 17 and pass through the soil-conditioning frame 8, thus not hindering the movement of the soil-conditioning frame 8, ensuring the smooth movement of the machine frame 1, and completely turning and conditioning the soil. The rear inner wall of the soil-conditioning frame 8 is provided with a leveling slope 19. The leveling slope 19 can guide and level the turned-up paddy field soil, and scrape the paddy field after turning and conditioning the soil flat. See Figure 4 , Figure 5 The soil leveling component 7 is located inside the mounting frame 10. When the walking component 3 stops, it drives the soil leveling component 7 to rotate. The soil leveling component 7 works in conjunction with the soil leveling frame 8 to level the soil in the plowed paddy field. The soil leveling component 7 includes a first piston cylinder 702 and a second piston cylinder 703 located inside the mounting frame 10. The first piston cylinder 702 is fixed to the inner top wall of the mounting frame 10, and the second piston cylinder 703 is fixed to the top of the soil leveling frame 8. A vent pipe 705 is connected to the bottom of the second piston cylinder 703. A vent pipe 705 penetrates the soil-forming frame 8 and communicates with the inner side of the soil-forming frame 8. The first piston cylinder 702 and the second piston cylinder 703 are respectively provided with a first piston plate 707 and a second piston plate 708. A movable rod 709 is provided between the first piston cylinder 702 and the second piston cylinder 703. Both ends of the movable rod 709 penetrate the first piston cylinder 702 and the second piston cylinder 703 respectively, and both ends of the movable rod 709 are fixedly connected to the first piston plate 707 and the second piston plate 708 respectively. The movable rod 709 has evenly spaced grooves on its side wall. These grooves allow for communication and compensation between the first piston cylinder 702, the second piston cylinder 703, and the outside air during movement, ensuring smooth movement of the movable rod 709, the first piston plate 707, and the second piston plate 708. A movable plate 701 is sleeved on the outer side of the movable rod 709. A magnetic suction plate 710 is fixedly sleeved on the side wall of the movable rod 709, located inside the movable plate 701. The magnetic suction plate 710 and the movable plate 709... A coil spring 704 is connected between the plates 701. Two electric telescopic rods 706 are installed on the inner top wall of the mounting bracket 10. The telescopic ends of the two electric telescopic rods 706 are fixed to the upper end of the moving plate 701. Both electric telescopic rods 706 are electrically connected to the pressure switch 306. When the pressing block 305 presses and triggers the pressure switch 306, the electric telescopic rods 706 are extended through the pressure switch 306. When the pressure switch 306 is not triggered, the electric telescopic rods 706 are in the retracted state. When the machine is turning and leveling the soil in paddy fields, the leveling frame 8 is submerged in the water. When the electric telescopic rod 706 extends, it can drive the moving plate 701 to move downward. At this time, the magnetic suction plate 710 is attracted to the lower end of the first piston cylinder 702. As the moving plate 701 moves downward, the coil spring 704 is stretched. When the moving plate 701 moves to its limit position, the tension of the coil spring 704 breaks through the magnetic attraction of the magnetic suction plate 710 when it is attracted to the first piston cylinder 702. The magnetic suction plate 710 is detached from the first piston cylinder 702, and under the action of the tension of the coil spring 704, it pulls the magnetic suction plate 701 to the lower end of the first piston cylinder 702. When plate 710 moves downward, it simultaneously drives movable rod 709 downward. Through 709, first piston plate 707 and second piston plate 708 move downward. When second piston plate 708 moves downward, it can force the air inside second piston cylinder 703 into soil frame 8 through vent pipe 705, thereby generating positive pressure inside soil frame 8. Using positive pressure to act on water, water can be forced into the soil, thus allowing water in paddy fields to penetrate the soil more fully and efficiently, especially the lower soil layer, thereby increasing the overall soil moisture content and better meeting the needs of rice cultivation.

[0028] See Figure 4 It also includes a fertilizer supply component 6 located at the top of the frame 1 and a fertilizer application component 5 located inside the soil preparation frame 8. The fertilizer supply component 6 includes a storage box 601 set at the top of the frame 1. The storage box 601 stores liquid fertilizer. A delivery pipe 602 is connected to the side wall of the storage box 601. The end of the delivery pipe 602 away from the storage box 601 is connected to the side wall of the first piston cylinder 702. A one-way valve is provided inside the delivery pipe 602. The liquid fertilizer can be unidirectionally input into the first piston cylinder 702 through the delivery pipe 602. When the movable rod 709 moves down, it can drive the first piston plate 707 to move down inside the first piston cylinder 702. Using the principle of negative pressure suction, the liquid fertilizer in the storage box 601 can be pumped into the first piston cylinder 702 through the delivery pipe 602. See Figure 7 The fertilization component 5 includes a distribution pipe 502 fixed on the top wall of the soil-forming frame 8. An output pipe 501 is connected to the upper side wall of the distribution pipe 502. The end of the output pipe 501 away from the distribution pipe 502 passes through the soil-forming frame 8 and is connected to the side wall of the first piston cylinder 702. A one-way valve is provided inside the output pipe 501. Liquid fertilizer can be unidirectionally input into the distribution pipe 502 through the output pipe 501. A discharge main pipe 503 arranged in a row is connected to the lower side wall of the distribution pipe 502. Discharge branch pipes 504 are evenly arranged on the side wall of the discharge main pipe 503. A discharge nozzle 505 is provided on the upper surface of the discharge branch pipe 504. By setting the discharge main pipe 503, the discharge branch pipe 504, and the discharge nozzle 505, uniform fertilization can be achieved. When the movable rod 709 moves upward, it drives the first piston plate 707 to move upward inside the first piston cylinder 702. Utilizing the principle of positive pressure extrusion, the liquid fertilizer in the first piston cylinder 702 can be pumped into the distribution pipe 502 through the output pipe 501. The liquid fertilizer is then sprayed out through the main discharge pipe 503, the branch discharge pipe 504, and the discharge nozzle 505, directly spraying the liquid fertilizer into the soil after the paddy field has been tilled. This directly replenishes the fertilizer into the soil, effectively improving the soil. Compared to surface fertilization, the fertilizer is less likely to be lost, and it is also beneficial for the later utilization of fertilizer by the rice. Furthermore, the fertilization process can be completed continuously after the paddy field has been tilled and prepared, effectively improving work efficiency.

[0029] See Figure 4 It also includes two sealing components 4, which are respectively installed on the front and rear walls of the soil-forming frame 8. Each sealing component 4 includes two guide strips 403 fixedly connected to the side wall of the soil-forming frame 8. The two guide strips 403 are respectively located on both sides of the channel 17. The same sealing plate 401 is slidably inserted into the inner side of the two guide strips 403. A connecting plate 402 is fixed to the upper side wall of the sealing plate 401. The connecting plate 402 penetrates the side wall of the mounting frame 10 and is fixedly connected to the movable plate 701. The side wall of the mounting frame 10 is penetrated by... A groove 18 is provided to cooperate with the connecting plate 402. The connecting plate 402 is slidably connected to the inner side of the groove 18. When the moving plate 701 moves down, the sealing plate 401 can be moved down through the connecting plate 402. The sealing plate 401 is inserted into the soil, thereby sealing the channels 17 at the front and back of the whole frame 8. This greatly reduces the water from escaping from the channels 17 when the positive pressure inside the whole soil frame 8 acts on the water, allowing the water to enter the soil more fully and further enhancing the effect of pressing water into the soil.

[0030] When using this invention, the operator first pushes the frame 1 through the two handrails 9 to make the walking wheels 301 contact the paddy field. After starting the motor 13, the output shaft of the motor 13 drives the reducer 14 to run. The reducer 14 transmits power to the turntable 303 to make the turntable 303 start to rotate. When the turntable 303 rotates, the incomplete gear ring 304 on its disc surface alternately meshes with the gear 302 on the side wall of the second rotating shaft 307. When the incomplete gear ring 304 meshes with the gear 302, the gear 302 is driven to rotate, thereby driving the second rotating shaft 307 to rotate. When the second rotating shaft 307 rotates, it drives the two end walking wheels 301 to rotate, so that the frame 1 can move. During the movement, the first rotating shaft 201 in the soil turning assembly 2 rotates synchronously with the second rotating shaft 307 through the first synchronous wheel 203, the second synchronous wheel 205 and the synchronous belt 204. The soil turning blade 202 on the first rotating shaft 201 performs soil turning operations. When the incomplete gear ring 304 rotates to the notch position, the incomplete gear ring 304 does not mesh with the gear 302, and the incomplete gear ring 304 will not drive the gear 302. At this time, the second rotating shaft 307 and the traveling wheel 301 do not rotate, and the frame 1 does not move. As the turntable 303 rotates, the pressing block 305 on its side wall triggers the pressure switch 306 on the inner wall of the first protective shell 15. At this time, the pressure switch 306 controls the electric telescopic rod 706 to extend. When the electric telescopic rod 706 extends, its telescopic end pushes the moving plate 701 to move down. During the downward movement of the moving plate 701, the magnetic suction plate 710 is magnetically attracted by the lower end of the first piston cylinder 702. The force temporarily attracts the magnetic plate. When the moving plate 701 moves down to the limit position, the connecting plate 402 in the sealing component 4 on the front and rear walls of the soil frame 8 moves down with the moving plate 701 and is inserted into the soil sealing channel 17 through the sealing plate 401. The tension of the coil spring 704 breaks through the magnetic attraction force, causing the magnetic plate 710 to detach from the first piston cylinder 702. Under the action of the tension of the coil spring 704, the movable rod 709 moves down. When the movable rod 709 moves down, it simultaneously drives the first piston plate 707 in the first piston cylinder 702 and the second piston plate 708 in the second piston cylinder 703 to move down. Then the magnetic plate 710 is attracted to the upper end of the second piston cylinder 703. The second piston plate 708 moves down and forces the air in the second piston cylinder 703 into the soil-forming frame 8 through the vent pipe 705, creating positive pressure inside the soil-forming frame 8. This positive pressure efficiently forces water into the soil, forcing the water to penetrate the lower soil layers more fully, increasing soil moisture content, and improving soil condition. At the same time, the first piston plate 707 moves down and draws liquid fertilizer from the storage box 601 into the first piston cylinder 702 through the delivery pipe 602. As the turntable 303 continues to rotate, the pressing block 305 moves away from the pressure switch 306. When the pressure switch 306 is not triggered by the pressing block 305, the electric telescopic rod 706 retracts. When the electric telescopic rod 706 retracts, the moving plate 701 moves upward. When the moving plate 701 moves upward, the connecting plate 402 drives the sealing plate 401 to move upward, releasing the closure of the channel 17. Similarly, when the moving plate 701 moves upward to its limit position, the tension of the coil spring 704 breaks through the magnetic attraction, causing the magnetic plate 710 to disengage from the second piston cylinder 703, and... Under the tension of the coil spring 704, the movable rod 709 moves upward. The upward movement of the movable rod 709 causes the first piston plate 707 and the second piston plate 708 to move upward. The upward movement of the first piston plate 707 pushes the liquid fertilizer in the first piston cylinder 702 into the distribution pipe 502 through the output pipe 501. The liquid fertilizer is evenly sprayed from the discharge nozzle 505 into the soil after soil preparation through the discharge main pipe 503 and the discharge branch pipe 504. The upward movement of the second piston plate 708 causes the second piston cylinder 703 to draw in air through the vent pipe 705. Then the frame 1 continues to move forward, driving the soil-setting frame 8 forward. The leveling slope 19 on the inner rear wall of the soil-setting frame 8 guides and levels the turned-up soil. Through the above process, continuous automated operation of turning, leveling, and uniformly fertilizing the paddy field is realized.

[0031] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
