Description

Technical Field

[0001] This utility model relates to the field of stubble breaking, turning, and land preparation machine technology, and in particular to a combined stubble breaking, turning, and land preparation machine for agricultural machinery promotion and marketing. Background Technology

[0002] Some straw stubble breaking, plowing, and land preparation machines on the market are multi-functional combined agricultural machines designed to solve two major agricultural pain points: straw processing and land preparation. They can replace the traditional step-by-step operation of multiple single machines, achieving one-stop field pre-treatment. First, the crushing device breaks up and removes the straw and stubble remaining after crop harvesting. Then, the plowshare or rotary tiller deeply plows and buries the crushed straw into the soil to avoid burning pollution and allow the straw to decompose into organic matter. Finally, the rear-end land preparation device rakes the soil, breaks up clods, and compacts the surface layer, making... The soil meets the requirements for sowing, with significant advantages. It can greatly improve operational efficiency, reduce farmers' equipment, labor, and fertilizer costs, improve soil, prevent compaction, improve aeration and water and fertilizer retention capacity, increase seed germination rate and crop yield, comply with environmental protection policies, reduce soil compaction to ensure sowing quality, and is suitable for various plots of land such as plains and hills and various crops. Its core value lies in cost reduction, efficiency improvement, soil protection, and environmental protection. It is especially suitable for plots with high straw production, such as corn-wheat rotation areas in northern China and rice-rapeseed rotation areas in southern my country. This type of straw stubble-breaking, burying, and tillage machine is built around three core functions: crushing, burying, and tillage. It is mainly composed of six parts working together to achieve one-stop operation. The power and walking components form the foundation, including a tractor-connected traction system, suspension mechanism, and power transmission devices such as gears, belts, and chains, providing power and mobility for the entire machine. The straw crushing and stubble processing device is located at the front, using high-speed rotating hammers, blades, and toothed discs to crush straw stubble. A protective cover and guide vane prevent splashing and guide the crushed material, and a crushing length adjustment mechanism adapts to different needs. The straw burying device receives the crushed material and flexibly turns it over with a plowshare or rotary tiller roller. The soil is buried, and the depth adjustment component controls the burial depth. The land preparation and compaction device is located at the rear. The disc rake and spiked rake break up soil clods and level the surface. Solid rubber and cast iron compaction wheels compact the surface layer, and a leveling plate refines the flatness, bringing the soil to a sowing state. The control and adjustment components include an operating panel with integrated control buttons that is linked to the tractor cab, a hydraulic mechanical adjustment mechanism, and an instrument panel that displays work data for convenient real-time control. Auxiliary components include a high-strength steel frame connecting various parts, safety protection devices such as guardrails and warning lights, and cleaning mechanisms such as scraper blades and debris removal teeth to ensure stable and safe operation of the machine. Some straw stubble breaking, plowing, and land preparation machines have certain drawbacks. When the rotating blades used for straw breaking and stubble treatment are damaged, they are difficult to replace, and replacing new blades is time-consuming. As a core working component, the blades are usually fixed to the rotating shaft or cutter roller with multiple bolts. When replacing them, the machine must be stopped and the external protective cover must be removed. In some models, the blade installation position is also relatively hidden, and the operating space is limited, making the process of removing old blades and installing new blades cumbersome. Generally, a replacement often takes a long time, during which the whole machine cannot be operated. If the blades are damaged during the critical window of the busy farming season, it will directly delay the progress of field treatment and thus affect subsequent agricultural arrangements such as sowing. Therefore, a straw stubble breaking, plowing, and land preparation machine for agricultural machinery promotion and application is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a combined straw breaking, turning, and burying tillage machine for agricultural machinery promotion and marketing, aiming to improve the problem of difficulty in replacing damaged rotating blades and the long time required for replacement in the existing technology.

A limiting ring is slidably connected inside the quick-release blade. A locking post is fixedly connected inside the limiting ring. A safety component is slidably connected inside the locking post. Preferred: The combined straw stubble breaking and burial tillage machine uses the tillage machine body as the core load-bearing component. Externally, it has a coupler block for connecting with the traction equipment and a transmission gearbox with a matching lubrication and sealing mechanism. The top is fixed with an oil tank and engine that power the whole machine. Internally, it has a rotatably connected tire height adjuster for adjusting the working height and a quick-release mechanism for straw breaking and burial blades. The quick-release mechanism for straw breaking and burial blades is supported by a main column. The outer end of the main column is rotatably connected to the mounting base inside and outside the tillage machine body for installing quick-release blades. The quick-release blades are slidably assembled in the mounting base. The limiting ring that is fixed to the locking post inside the quick-release blades locks the quick-release blades through the sliding contact of the locking post. The locking post also has a sliding safety component inside to prevent the locking post from accidentally sliding and causing the blades to fall off. The overall structure provides basic support for the safe and convenient disassembly and assembly of quick-release blades and subsequent stable operation. As a further description of the above technical solution: The lubrication sealing mechanism includes a lubrication port, the bottom of which is fixedly connected to the top of the transmission gearbox. A sealing cover is slidably connected to the outside of the lubrication port, a push post is slidably connected to the inside of the sealing cover, and a connecting block is rotatably connected to the outside of the push post. Preferred configuration: When the transmission gearbox needs to be lubricated, based on this structure, press the push button inside the sealing cover. The push button will drive the connecting block connected to it to move. When the sliding locking tongue disengages from the lubrication port slot, the sealing cover on the outside of the lubrication port can be slid off for lubrication. After lubrication, press the push button again and put the sealing cover back on the top of the lubrication port. The push button will drive the connecting block and the sliding locking tongue to slide out of the sealing cover, so that the sliding locking tongue can be engaged in the lubrication port. Finally, through the cooperation of the push button, the connecting block, the sealing cover, and the lubrication port, the sealing cover can be quickly unlocked, installed, and sealed, ensuring the convenience of lubricating oil addition and the sealing performance of the transmission gearbox. As a further description of the above technical solution: The safety assembly includes a push-button post, the outside of which is slidably connected to the inside of the locking post, and a limit plate is fixedly connected to the bottom of the push-button post. Preferred configuration: The push pin slides inside the locking pin. When changing the blade, the push pin is pressed, which moves the bottom fixed limit plate. After the blade is installed, the limit plate returns to its original position with the push pin, so that the push pin is locked outside the mounting base, preventing the locking pin from being pushed accidentally. As a further description of the above technical solution: The right end of the locking pin is fixedly connected to a bottom support ring, the outside of which is slidably connected to the inside of the quick-release blade, and the outside of which is slidably connected to the inside of the mounting base. Preferably, the bottom ring fixed at the right end of the locking pin can slide inside the quick-release blade and the mounting base, and the locking pin moves when the blade is replaced; As a further description of the above technical solution: A spring is fixedly connected to the right end of the bottom support ring, and the right end of the bottom support ring is fixedly connected to the inside of the mounting base. Preferably, the spring fixed at the right end of the bottom ring is connected to the inside of the mounting base. When the blade is replaced, the bottom ring is driven to the right to compress the spring, so that the bottom ring moves out of the quick-release blade. After the new blade is installed, the spring rebounds and pushes the bottom ring to the left to reset, sliding into the quick-release blade to achieve fixation. As a further description of the above technical solution: A second spring is fixedly connected to the bottom of the push post, and the bottom of the second spring is fixedly connected to the inside of the locking post. Preferred configuration: The bottom of the push-button pin is fixed to the second spring, which is fixed inside the locking pin. When the locking pin needs to be operated to replace the quick-release blade, the push-button pin is pressed. The push-button pin compresses the second spring at the bottom downward and drives the limiting piece to move. After the new blade is installed and the locking pin is reset, the compressed second spring elastically rebounds and pushes the push-button pin upward to reset, so that the push-button pin is stuck outside the mounting base, which restricts the locking pin from being pushed accidentally and prevents the blade from being unlocked accidentally. As a further description of the above technical solution: The bottom of the limiting piece is slidably connected to a spring three, and the bottom of the spring three is fixedly connected to the inside of the sealing cover. Preferably, the bottom of the limiting plate is slidably connected to the spring three, which is fixed inside the sealing cover. When the transmission gearbox needs to be lubricated, the pressing post moves the limiting plate downward, the limiting plate compresses the spring three at the bottom, and at the same time moves the sliding locking tongue out of the lubrication port groove, making it easy to remove the sealing cover. After the lubrication is completed, the sealing cover is put back on, the pressing post is released, the compressed spring three elastically rebounds, pushes the limiting plate and the pressing post upward to reset, and pushes the sliding locking tongue into the lubrication port groove, so as to realize the quick fixation and sealing of the sealing cover. As a further description of the above technical solution: The left end of the connecting block is rotatably connected to a sliding latch, and the outside of the sliding latch is slidably connected to the inside of the sealing cover. Preferred configuration: The sliding locking tongue, rotatably connected to the left end of the connecting block, is externally slidably connected inside the sealing cover. When the transmission gearbox needs to be lubricated, pressing the push post moves the connecting block. The connecting block, through rotation, causes the sliding locking tongue to slide inside the sealing cover, disengaging it from the lubrication port groove, making it easy to remove the sealing cover. After lubrication is completed, the sealing cover is replaced, the push post is released, and the spring rebounds, pushing the push post and connecting block back to their original positions. The connecting block then causes the sliding locking tongue to slide in the opposite direction inside the sealing cover, causing it to engage with the lubrication port groove, thus achieving rapid fixing and sealing of the sealing cover.

[0005] This utility model has the following beneficial effects: 1. In this utility model, the pressing column structure drives the limiting plate structure to work. The limiting plate presses down on the second spring. At the same time, the locking column structure drives the limiting ring and the bottom support ring structure to work. The limiting ring and the bottom support ring move to the right and compress the first spring, so that the bottom support ring disengages from the quick-release blade to remove the old blade. After the new blade is inserted, the first spring rebounds and pushes the bottom support ring and the locking column to reset. The second spring rebounds and drives the limiting plate and the pressing column to reset and lock the mounting base, realizing the function of safe and quick replacement of quick-release blades. Compared with the prior art, it has the effect of avoiding danger caused by accidental unlocking of quick-release blades and ensuring the safety of the blade replacement process.

[0006] 2. In this utility model, the pressing column structure drives the connecting block structure to work. The connecting block drives the sliding locking tongue to slide inward. In conjunction with the pressing column pressing down the spring three, the sealing cover is disengaged from the lubrication port. After lubricating oil is added, the spring three rebounds and drives the pressing column, connecting block and sliding locking tongue to reset. The sliding locking tongue is engaged in the lubrication port groove, realizing the function of quick disassembly and assembly of the transmission gearbox lubrication port sealing cover and strengthening the seal. Compared with the prior art, it simplifies the lubrication oil filling process and improves the sealing reliability of the lubrication port. Attached Figure Description

This fixed connection ensures that the lubrication port 46 is completely connected and tightly connected to the inside of the transmission gearbox 2, which not only avoids leakage when adding lubricating oil, but also allows the injected lubricating oil to flow accurately into the inside of the transmission gearbox 2 and directly act on the gears and other components that need lubrication, ensuring that the lubrication effect reaches the core. The lubrication port 46 is slidably connected to a sealing cover 41. The sliding connection design allows the sealing cover 41 to be flexibly installed and removed. When lubricating oil needs to be added, it can be quickly slid off from the outside of the lubrication port 46. When not adding lubricating oil, it can be tightly fitted to the outside of the lubrication port 46. On the one hand, it prevents dust and impurities in the air from entering the transmission gearbox 2, and on the other hand, it prevents the internal lubricating oil from evaporating or leaking from the lubrication port 46, taking into account both the convenience of operation and the reliability of sealing. Specifically, the lubrication sealing mechanism 4 includes a lubrication port 46, which is the core channel for adding lubricating oil. It provides structural support for replenishing oil to the transmission gearbox 2 and is the key to connecting external filling and gearbox lubrication needs. The bottom of the lubrication port 46 is fixed to the top of the transmission gearbox 2 to ensure a tight connection to prevent leakage and to ensure that the lubricating oil flows accurately into the core component to ensure the lubrication effect. The lubrication port 46 is externally connected to a sealing cover 41. When filling is required, the sealing cover 41 can be quickly removed. When not filling, it fits tightly to prevent impurities from entering and lubricating oil from leaking, thus balancing convenience and sealing.

[0019] The sealing cover 41 has a sliding connection to a push post 42 inside. This sliding connection allows the push post 42 to move smoothly up and down inside the sealing cover 41. As a direct triggering component for user operation, it provides an operating fulcrum for locking and unlocking the sealing cover 41 and the lubrication port 46, ensuring that the action transmission is smooth. The bottom of the push post 42 is slidably connected to a spring 43. The sliding connection allows the spring 43 to be compressed when the push post 42 is pressed down. After the push post 42 is released, the spring 43 can push the push post 42 to automatically return to its original position by its own elastic force, providing stable elastic support for the reciprocating action of the push post 42. It can achieve automatic return after operation without manual adjustment, ensuring the continuity of subsequent locking actions. The bottom of the spring 43 is fixedly connected to the inside of the sealing cover 41. This fixed connection provides a stable installation reference for the spring 43, ensuring that the spring 43 will not shift or fall off during compression and rebound. It can continuously and stably transmit elastic force to the push post 42, making the reset action of the push post 42 precise and controllable, thereby ensuring a stable and reliable locking effect. Specifically, the sealing cover 41 is internally connected to the push post 42, which can move smoothly up and down within the sealing cover 41. This push post 42 serves as an operating fulcrum to ensure that the locking and unlocking actions of the sealing cover 41 and the lubrication port 46 are smooth. The bottom of the push post 42 is slidably connected to the spring 43. When the push post 42 is pressed down, the spring 43 is compressed and released. The spring 43 pushes the push post 42 to automatically reset, providing stable elastic support for the reciprocating action of the push post 42 and ensuring the continuity of subsequent locking actions. The bottom of the spring 43 is fixedly connected to the inside of the sealing cover 41, providing a stable installation reference for the spring 43 to prevent it from shifting or falling off. It continuously and stably transmits force to the push post 42, making the reset of the push post 42 precise and controllable, and ensuring a stable and reliable locking effect.

[0020] A connecting block 44 is rotatably connected to the outside of the push post 42. This rotatable connection allows the connecting block 44 to rotate flexibly with the up-and-down movement of the push post 42, converting the vertical linear motion of the push post 42 into a lateral pushing motion, thus achieving a change in the direction of action. It is a key transmission component that connects the operation of the push post 42 and realizes the locking function, ensuring that the actions of the two are coordinated and consistent. A sliding latch 45 is rotatably connected to the left end of the connecting block 44. This rotatable connection allows the rotational motion of the connecting block 44 to be accurately transmitted to the sliding latch 45, causing the sliding latch 45 to slide laterally inside the sealing cover 41, thereby realizing the sliding latch. The engagement or disengagement of the sliding latch 45 with the lubrication port 46 is the core transmission connection point for fixing and disassembling the sealing cover 41. The external sliding connection of the sliding latch 45 is inside the sealing cover 41. The sliding connection provides a stable lateral movement trajectory for the sliding latch 45, ensuring that the sliding latch 45 can be accurately aligned with the lubrication port 46. When locked, it can be tightly engaged in the slot to firmly fix the sealing cover 41. When unlocked, it can be smoothly disengaged from the slot without hindering the removal of the sealing cover 41. This avoids locking failure or disassembly jamming due to offset, ensuring the fixing reliability and disassembly convenience of the sealing cover 41. Specifically, the external connecting block 44 of the push post 42 moves flexibly with the push post 42, converting vertical movement into horizontal movement to achieve action conversion. It is a key transmission component connecting the operation and locking functions of the push post 42, ensuring coordinated action. The left end of the connecting block 44 is connected to the sliding latch 45, and its rotation is accurately transmitted to the sliding latch 45, causing it to slide horizontally inside the sealing cover 41, realizing engagement or disengagement with the lubrication port 46 slot. It is the core transmission point for fixing and disassembling the sealing cover 41. The external sliding connection of the sliding latch 45 to the inside of the sealing cover 41 provides a stable horizontal movement trajectory, ensuring accurate alignment with the lubrication port 46 slot. When locked, it tightly engages with the sealing cover 41, and when unlocked, it smoothly disengages without hindering removal, avoiding displacement that could lead to locking failure or jamming during disassembly and assembly, ensuring reliable fixing and convenient disassembly.

[0021] The implementation principle of this application embodiment is as follows: When the user needs to replace the quick-release blade 33 during use, first stop the engine 5. After stopping, locate the faulty quick-release blade 33, press the actuating pin 381. The actuating pin 381 will cause the limiting plate 382 to move downward and press the second spring 383. At this time, push the locking pin 34 to the right. The locking pin 34 will cause the limiting ring 37 and the bottom support ring 36 to move to the right and press the first spring 35. The interior of the quick-release blade 33 is wider in the middle and narrower on both sides. The middle part can slide up and down on the first spring 35, while the two sides of the quick-release blade 33 can only slide up and down on the locking pin 34. Therefore, at this time, when the bottom support ring 36 is pushed out of the interior of the quick-release blade 33... When spring 1 35 is pushed to the middle part of quick-release blade 33, quick-release blade 33 can be removed and a new quick-release blade 33 can be inserted. When spring 1 35 is released, it will push the bottom ring 36 to the right. The bottom ring 36 will drive the locking pin 34 and the limiting ring 37 to slide to the right. Spring 1 35 and the bottom ring 36 will be reinserted on both sides of quick-release blade 33, making quick-release blade 33 unable to disengage. Spring 2 383 will rebound when the locking pin 34 is pushed out to the right into the mounting base 32, pushing the limiting piece 382 and the pressing pin 381 upward, so that the pressing pin 381 is stuck on the outside of the mounting base 32, thereby preventing the locking pin 34 from being pushed and avoiding accidental unlocking of quick-release blade 33 and causing danger. When the transmission gearbox 2 needs to be lubricated, press down on the push post 42. The push post 42 will move the connecting block 44, which will cause the sliding locking tongue 45 to slide inward. At the same time, the push post 42 will press the spring 3 43. When the sliding locking tongue 45 disengages from the groove of the lubrication port 46, the sealing cover 41 can be removed. After lubrication is completed, press the push post 42 again, cover the top of the lubrication port 46 and release. The spring 3 43 will push the push post 42 upward. The push post 42 will cause the connecting block 44 and the sliding locking tongue 45 to slide outward, so that the sliding locking tongue 45 can be inserted into the interior of the lubrication port 46, achieving the effect of quick fixation and enhanced sealing.
