Description

A deep-rotary tiller Technical Field

[0001] This utility model relates to the field of agricultural implements technology, specifically a deep-rotating rotary tiller. Background Technology

[0002] With the development of agricultural modernization, traditional rotary tillers have limited operating depth, generally 8-15cm. Long-term use leads to a shallower topsoil layer and a rising plow pan, affecting crop root growth and the soil's water retention capacity. Some crops, such as potatoes and cotton, require a deeper topsoil layer to ensure full root development and the absorption of more water and nutrients. Simultaneously, to improve soil fertility and aeration, it is also necessary to break up the plow pan, promoting soil maturation and microbial activity.

[0003] The rotary tillers currently on the market are mainly half-shaft rotary tillers, with the tiller blades welded to a disc and symmetrically distributed on both sides; the left and right blade shaft bearing seats are protected by wear-resistant plates. However, these wear-resistant plates are prone to wear after long-term operation, making them less practical.

[0004] To address the aforementioned issues, a deep-rotation rotary tiller is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a deep-rotation rotary tiller that solves the problem in the prior art where the left and right blade shaft bearing seats are protected by wear-resistant plates. However, these plates tend to wear out easily during long-term operation, making them impractical.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deep-rotation rotary tiller, comprising a frame, with cutter shaft seats fixedly connected to the lower sides of both sides of the frame; a drive housing is fixedly connected through and to the center of the frame; a motor is fixedly connected to the upper outer side of the drive housing; a first pulley is fixedly connected to the output end of the motor; a cutter shaft is rotatably connected through and to the lower part of the drive housing; both ends of the cutter shaft are rotatably connected to the cutter shaft seats; uniformly distributed cutter discs are fixedly connected to both sides of the outer ring of the cutter shaft; a uniformly distributed cutter magazine is provided on the outer ring of the cutter discs; rotary tillage blades are provided in the cutter magazine; and a cutter shaft seat is provided on the lower inner side of both cutter shaft seats. The machine is equipped with a side plowshare, and a trenching plowshare is fixedly connected to the outer side of the lower part of the drive housing. Cover plates are provided on both sides of the top of the frame. Mounting blocks are fixedly connected to the front, rear, left and right sides of the top of the cover plates. The mounting blocks have slots on the outward side. Mounting seats are provided on the outer side of the mounting blocks, and the bottom of the mounting seats is fixedly connected to the frame. The mounting seats have telescopic grooves on the inward side. Insert blocks are slidably connected in the telescopic grooves. Two first springs are fixedly connected to the inward side of the insert blocks, and the ends of the first springs are fixedly connected to the telescopic grooves. The top of the mounting seats has guide grooves that communicate with the telescopic grooves. A soil-dragging assembly is provided at the rear of the frame.

[0007] By adopting the above technical solution, by pulling the push-pull frame outward, the two insert blocks can be driven to squeeze the first spring and retract into the telescopic groove at the same time, thereby realizing the insertion block being pulled out from the slot of the mounting block, which facilitates the disassembly of the cover plate and the inspection of the inside of the frame.

[0008] As a further description of the above technical solution: the soil-dragging assembly includes a soil-dragging plate and a limiting frame. The top of the soil-dragging plate is rotatably connected to the frame, and the bottoms of the two limiting frames are fixedly connected to the rear sides of the frame. A sliding rod is rotatably connected to the outside of the soil-dragging plate, and a rotating frame is rotatably connected to the inside of the limiting frame. The sliding rod passes through and is slidably connected to the rotating frame. A second spring is sleeved on the outer ring of the sliding rod, and a limiting ring is fixedly connected to the middle of the outer ring of the sliding rod. The second spring is disposed between the limiting ring and the rotating frame.

[0009] By adopting the above technical solution, the soil-dragging component can rotate under force when encountering different terrains or soil resistance, causing the slide bar to slide within the rotating frame. The second spring plays a buffering and adjusting role, ensuring that the soil-dragging plate always maintains appropriate contact pressure with the ground, leveling and compacting the rotary tilled land, improving the flatness and compaction of the land, and providing a good foundation for subsequent operations.

[0010] As a further description of the above technical solution: a second pulley is fixedly connected to the middle of the outer ring of the cutter shaft. The second pulley is disposed in the drive housing, and both the outer rings of the second pulley and the first pulley are provided with belts.

[0011] By adopting the above technical solution, a transmission function is achieved, so that when the first pulley rotates, it can drive the second pulley to rotate via the belt.

[0012] As a further description of the above technical solution: a first bolt is provided through the blade magazine, and the first bolt penetrates the rotary tiller blade.

[0013] By adopting the above technical solution, the first bolt passes through the blade magazine and the rotary tiller blade inside the blade magazine, and the nut allows for convenient fixing, installation, and disassembly of the rotary tiller blade.

[0014] As a further description of the above technical solution: a second bolt is provided through both of the side plowshares, and the second bolt passes through the cutter shaft seat.

[0015] By adopting the above technical solution, the second bolt passes through the side plowshare and the cutter shaft seat, which, in conjunction with the nut, facilitates the fixing, installation, and disassembly of the side plowshare.

[0016] As a further description of the above technical solution: the outer end of the insert is disposed in the slot, and the outer side of the insert is slidably connected to the inner wall of the slot.

[0017] By adopting the above technical solution, it is easy for the insert block to be inserted into or removed from the slot.

[0018] As a further description of the above technical solution: a push-pull bracket is fixedly connected between the tops of the two left and right insert blocks, and the push-pull bracket passes through the guide groove.

[0019] By adopting the above technical solution, the push-pull bracket can slide along the guide groove.

[0020] As a further description of the above technical solution: a suspension frame is fixedly connected to the top center of the frame, and the suspension frame is located on the outside of the drive housing.

[0021] By adopting the above technical solution, the suspension frame serves as a connecting component between the rotary tiller and traction equipment such as tractors. Through the suspension frame, the rotary tiller can be stably suspended behind the tractor, achieving a reliable connection between the two.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model provides a deep-rotating rotary tiller, which firstly utilizes the coordinated operation of a cutter shaft seat, a second bolt, side plowshares, a cover plate, a mounting block, a slot, a guide groove, a mounting base, a telescopic groove, insert blocks, a first spring, a guide groove, and a push-pull frame. By installing side plowshares on the lower sides of the frame, the machine can easily be lowered into the ground. Furthermore, the movement of the lower sides of the frame and the cutter shaft seat on the loosened soil after plowing reduces wear. The rotary tiller blades, side plowshares, and other components are fixed with bolts for easy replacement and maintenance. Moreover, by pulling the push-pull frame outwards, two insert blocks can simultaneously compress the first spring and retract into the telescopic groove, thereby allowing the insert blocks to be pulled out of the slots in the mounting block, facilitating the disassembly of the cover plate and the inspection of the internal structure of the frame.

[0024] 2. The deep-rotating rotary tiller provided by this utility model can rotate when encountering different terrains or soil resistance through the soil-dragging component. This causes the dragging plate to rotate under force, driving the slide bar to slide within the rotating frame. The second spring plays a buffering and adjusting role, ensuring that the dragging plate always maintains appropriate contact pressure with the ground. This flattens and compacts the tilled land, improving the flatness and compactness of the land and providing a good foundation for subsequent operations. Attached Figure Description

[0036] Working Principle: After the motor 4 starts, its output end drives the first pulley 5 to rotate. The first pulley 5 transmits power to the second pulley 7, which is located inside the drive housing 3, via the belt 8. The second pulley 7 is fixedly connected to the cutter shaft 6, thereby driving the cutter shaft 6 to rotate. The two ends of the cutter shaft 6 are rotatably connected to the cutter shaft seat 2, ensuring the stability and reliability of the cutter shaft 6 during rotation and realizing the effective transmission of power from the motor 4 to the cutter shaft 6. When the cutter shaft 6 rotates, the cutter discs 9 fixed on both sides of its outer ring rotate accordingly. Rotary tillage blades 11 are installed in the blade magazine 10 on the outer ring of the cutter disc 9 and are fixed by the first bolt 12. When the cutter disc 9 rotates at high speed, the rotary tillage blades 11 cut into the soil, performing deep rotary tillage, breaking, stirring, and turning the soil to achieve the purpose of loosening the soil and improving the soil structure. The evenly distributed cutter discs 9 and rotary tillage blades 11 ensure the uniformity and depth of tillage and improve the tillage quality. During the operation of the rotary tiller, the side moldboards 13 on the inner side of the two cutter shaft seats 2 and the furrowing moldboards 15 on the outer side of the drive housing 3 play a role. The side moldboard 13 is fixed to the cutter shaft seat 2 by the second bolt 14, and the trenching moldboard 15 is fixed below the drive housing 3. As the machine moves forward, these components cut and push the soil, forming ridges on both sides and creating furrows in the middle, thus achieving the function of furrowing and ridging. The side plows 13 allow the lower sides of the frame 1 and the cutter shaft seat 2 to move on the loosened soil after plowing, reducing wear. Pulling the push-pull frame 21 outward can simultaneously drive the two insert blocks 18 to squeeze the first spring 19 and retract into the telescopic groove 17, thereby allowing the insert blocks 18 to be pulled out of the slots 24 of the mounting block 23, facilitating the disassembly of the cover plate 22 and the inspection of the inside of the frame 1. When encountering different terrains or soil resistance, the soil-dragging plate 25 rotates under force, causing the slide rod 26 to slide within the rotating frame 29. The second spring 28 acts as a buffer and adjuster, ensuring that the soil-dragging plate 25 always maintains appropriate contact pressure with the ground, leveling and compacting the tilled land, improving the flatness and compaction of the land, and providing a good foundation for subsequent operations.
