Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a strip tillage device and a strip tillage machine. Background Technology

[0002] No-till farming requires covering the soil surface with straw, which effectively achieves conservation tillage and is worthy of widespread promotion. However, in low-temperature climate zones, traditional no-till farming is not suitable due to their unique temperature characteristics. This is because winters in low-temperature climate zones are extremely cold, with temperatures remaining consistently low. If straw is completely covered on the surface, it will severely hinder the rise in surface temperature when the weather warms up. At planting season, a series of problems will arise, such as excessively low soil temperature and excessive moisture. This will not only affect seed germination and growth but also cause difficulties for machinery movement and equipment blockages, greatly increasing the difficulty of machinery operation and impacting efficiency.

[0003] Strip tillage technology can clear straw from the soil surface and loosen the soil, achieving full straw return to the field. It is low-carbon and environmentally friendly, increasing soil fertility while also improving seedling emergence rate and grain yield, thus ensuring food security. Strip tillage is typically implemented using strip tillage machines. The inventors understand that the straw cleaning devices used in strip tillage implements can be either driven or active. The driven type involves the straw cleaning device rotating under the traction of a traction device. This method is ineffective when dealing with large amounts of thick straw, resulting in poor cleaning and frequent clogging. The active type involves the straw cleaning device connected to a power unit, rotating under its drive. This type of device typically cleans multiple strips at a time, offering high overall rigidity but poor flexibility, making it difficult to adapt well to uneven terrain. Summary of the Invention

[0004] The purpose of this invention is to provide a strip tillage device and a strip tillage machine to solve the problems existing in the prior art. By setting straw-clearing blades with a spiral trajectory distribution, straw can be pushed to the side to achieve straw clearing. At the same time, the strip tillage device forms a tillage strip in one pass. The device is more compact and the adjustment is more flexible. Moreover, the strip tillage devices do not affect each other, which is conducive to improving the straw clearing effect.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] A strip tillage device includes a mounting frame, a straw cleaning mechanism, and a transmission mechanism. The straw cleaning mechanism includes a rotating component mounted on the mounting frame that rotates about an axial direction, and straw-cleaning blades spaced along a spiral trajectory on the surface of the rotating component, the spiral trajectory being coaxial with the rotating component. The axial length of the straw-cleaning blades is adapted to the width of a single tillage strip. The transmission mechanism is mounted on the mounting frame, with its power input end connected to a drive mechanism and its power output end connected to the rotating component to drive the rotating component to rotate.

[0007] In one embodiment, the straw-clearing knife has multiple spiral tracks distributed in opposite spiral directions, with the starting ends of the multiple spiral tracks located at the middle of the rotating member in the axial direction; and the ending ends of the multiple spiral tracks are respectively located at both ends of the rotating member.

[0008] In one embodiment, the pitch of the helical trajectory is uniform or gradually increases along the axial direction.

[0009] In one embodiment, the two side walls of the straw-cleaning knife are inclined along the direction of the spiral trajectory.

[0010] In one embodiment, the straw-cleaning knife is a straight knife, a right-angle knife, or a spiral knife.

[0011] In one embodiment, the rotating component includes a straw-cleaning shaft and a roller coaxially fixed on the straw-cleaning shaft. The straw-cleaning shaft is rotatably mounted on the mounting frame, and the surface of the roller is fixed with straw-cleaning knives via a knife holder.

[0012] In one embodiment, the transmission mechanism includes an input shaft rotatably mounted on the mounting frame, and sprockets are fixed on both the input shaft and the straw-cleaning shaft, the sprockets being connected by a chain drive.

[0013] In one embodiment, the mounting frame includes a main beam plate, on which are provided a deep loosening shovel, a ridging device bracket, and a press wheel bracket, all of which have lifting and adjusting functions. The bottom end of the ridging device bracket is provided with a pair of notched harrow blades, and the bottom end of the press wheel bracket is provided with a press wheel. The axial length of the press wheel is adapted to the width of a single tillage strip. Along the traveling direction of the mounting frame, the deep loosening shovel, the notched harrow blades, and the press wheel are arranged sequentially from front to back.

[0014] In one embodiment, the mounting frame includes a front mounting plate, a rear mounting plate, and a compression spring. The front mounting plate is detachably connected to a traction device or a traction frame. Flanges are provided on both sides of the front mounting plate, and a top plate is connected to the top of the front mounting plate. An upper rotating shaft and a lower rotating shaft are provided between the two flanges. An upper connecting rod and a lower connecting rod are respectively fixed to the upper rotating shaft and the lower rotating shaft. The ends of the upper connecting rod and the lower connecting rod are hinged to the rear mounting plate. The rear mounting plate is fixedly connected to the main beam plate. The lower connecting rod is connected to a vertical rod via a connecting shaft. The top end of the vertical rod passes through the top plate, and the compression spring is sleeved on the vertical rod. The top and bottom ends of the compression spring are fixed to the top plate and the connecting shaft, respectively. A rotating component is rotatably connected to a rotating component mounting plate, and the rotating component mounting plate is fixedly connected to the rear mounting plate via a connecting plate.

[0015] The present invention also provides a strip tillage machine, including a traction frame and at least one strip tillage device as described above, fixed on the traction frame; if there is one strip tillage device, the input shaft is drivenly connected to the output end of the drive mechanism; if there are two or more strip tillage devices, at least one input shaft is drivenly connected to the output end of the drive mechanism, and the input shafts of adjacent strip tillage devices are connected by couplings.

[0016] The present invention has the following technical advantages over the prior art:

[0017] In this invention, the rotating component is connected to the driving mechanism through the transmission mechanism to perform active straw cleaning operation, and the straw cleaning blades are distributed along the spiral trajectory. When the straw cleaning blades pick up the straw, the straw will be pushed to the side under the drive of the straw cleaning blades distributed along the spiral trajectory, thereby realizing the cleaning of the straw.

[0018] In this invention, the axial length of the straw-clearing blades is adapted to the width of a single tillage strip. Driven by the traction device, a tillage strip is formed in one pass. The overall device is more compact, and the number of strip tillage devices installed on the traction device can be selected according to the actual width of the tillage, making the adjustment more flexible. The strip tillage devices do not affect each other. When one strip tillage device moves, the impact on the adjacent tillage devices is minimal, which makes it easier for each strip tillage device to better adapt to the undulations of the ground and improve the straw-clearing effect.

[0019] In this invention, there are gaps between the straw-cleaning blades, so while sweeping the straw, the soil that is lifted will fall between adjacent straw-cleaning blades instead of being pushed sideways. Therefore, during the straw-cleaning process, the strip tillage device in this invention will not remove the surface soil along with the straw, and can form a section of bare soil, thus ensuring the requirements for cultivation.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The purpose of this invention is to provide a strip tillage device and a strip tillage machine to solve the problems existing in the prior art. By setting straw-clearing blades with a spiral trajectory distribution, straw can be pushed to the side to achieve straw clearing. At the same time, the strip tillage device forms a tillage strip in one pass. The device is more compact and the adjustment is more flexible. Moreover, the strip tillage devices do not affect each other, which is conducive to improving the straw clearing effect.

[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Example 1:

[0045] like Figures 1 to 18As shown, this embodiment provides a strip tillage device, including a mounting frame 1, a straw cleaning mechanism, and a transmission mechanism. The straw cleaning mechanism includes a rotating component 5 mounted on the mounting frame 1 that rotates axially, and straw-cleaning blades 51 spaced along a spiral trajectory on the surface of the rotating component 5. The spiral trajectory is coaxial with the rotating component 5; there can be one spiral trajectory or multiple spiral trajectories spaced circumferentially along the rotating component 5. The axial length of the straw-cleaning blades 51 is adapted to the width of a single tillage strip. The transmission mechanism is mounted on the mounting frame 1. The power input end of the transmission mechanism is used to connect to a drive mechanism. In one embodiment, the drive mechanism can be a drive mechanism on a traction device, such as a diesel engine; in another embodiment, a separate small engine can be mounted on the mounting bracket or on the traction frame 2 between the mounting bracket and the traction device. The power output end of the transmission mechanism is used to connect to the rotating component 5 to drive the rotating component 5 to rotate around its axis.

[0046] In use, the mounting frame 1 is directly or via the traction frame 2 connected to the rear end of the traction equipment, operating under the traction of the traction equipment. The drive mechanism drives the rotating component 5 to reverse, i.e., the traction equipment moves forward, and the straw-cleaning blades 51 on the front surface of the rotating component 5 rotate upward, lifting the straw upward. Because the straw has a certain length and the straw-cleaning blades 51 are distributed along a spiral trajectory, the straw is pushed to the side by the straw-cleaning blades 51 distributed along the spiral trajectory, thus cleaning the straw on the surface of the cultivated strip. At the same time, the drive mechanism is connected to the transmission mechanism for active straw cleaning, resulting in higher work efficiency. Furthermore, in this embodiment, the axial length of the straw-clearing blades 51 is adapted to the width of a single tillage strip. Driven by the traction device, a tillage strip is formed in one pass. The overall device is more compact, and the number of strip tillage devices installed on the traction device can be selected according to the actual width of the tillage, making the adjustment more flexible. The strip tillage devices do not affect each other. When one strip tillage device undulates, the impact on the adjacent tillage devices is minimal, which makes it easier for each strip tillage device to better adapt to the undulations of the ground surface and improve the straw-clearing effect.

[0047] In addition, because there are gaps between the straw-clearing blades 51 in this embodiment, the soil that is swept up will fall between adjacent straw-clearing blades 51 while it is clearing straw, and will not be pushed to the side. Therefore, during the straw clearing process, the strip tillage device in this embodiment will not remove the surface soil along with the straw, and can form a section of bare soil, thus ensuring the requirements for cultivation.

[0048] In one implementation, such as Figure 10 , Figure 11As shown, the straw-clearing blade 51 has multiple spiral tracks distributed along opposite spiral directions. In a specific example, the number of spiral tracks with opposite spiral directions is the same. By setting multiple spiral tracks in opposite directions, the straw can be pushed from the middle to both sides. Taking two spiral tracks with opposite spiral directions as an example: the starting ends of the two spiral tracks are located at the middle of the axially rotating member 5; the ending ends of the two spiral tracks are located at the two ends of the rotating member 5 respectively; as an implementation example of two spiral tracks, the two spiral tracks are symmetrical with respect to the vertically set central plane of the rotating member 5.

[0049] In one embodiment, the pitch of the helical trajectory is uniform or gradually increases along the axial direction, such as... Figures 8-11 As shown.

[0050] In one embodiment, the two side walls of the straw-cleaning blade 51 are inclined along the spiral trajectory direction to improve the lateral pushing efficiency of the straw.

[0051] In one embodiment, the straw-cleaning knife 51 is a straight knife 511, a right-angle knife 512, or a spiral knife 513. The straight knife 511 has a straight blade and a cutting edge using a traditional knife-cutting edge, making it easier to cut straight lines, such as... Figure 16 As shown. If the straw is too fine, use the right-angle knife 512 for better sweeping effect. The blade of the right-angle knife 512 is right-angled, with the bend line located at about 1 / 3 of the way down the front side of the blade. To fit the blade, the cutting edge adopts a single bevel edge design, as shown. Figure 18 As shown. If there are too many weeds on the ground, a spiral blade 513 with better anti-weed entanglement effect can be used. The blade of the spiral blade 513 conforms to the Archimedean spiral, and the sliding angle of this curve gradually increases with the increase of the radius of rotation, such as... Figure 17 As shown, it can effectively prevent straw tangling while ensuring straw clearing operations. The blade adopts a beveled scissor blade, which can reduce shearing resistance and improve straw cutting efficiency.

[0052] In one embodiment, the rotating component 5 includes a straw-cleaning shaft 52 and a roller 53 coaxially fixed on the straw-cleaning shaft 52. The roller 53 may be a hollow structure. The straw-cleaning shaft 52 is rotatably mounted on the mounting frame 1 via a fixed bearing 55, and straw-cleaning blades 51 are fixed to the surface of the roller 53 via a blade holder 54.

[0053] In one embodiment, the transmission mechanism includes an input shaft 6 rotatably mounted on the mounting frame 1. Both the input shaft 6 and the straw-cleaning shaft 52 are fixed with sprockets 7, which are connected via chain drive. Chain drive is more stable and has higher transmission efficiency. Those skilled in the art can also adjust the straw-cleaning efficiency by adjusting the power of the drive mechanism.

[0054] In one embodiment, the mounting frame 1 includes a main beam plate 101, on which are mounted a deep tillage shovel 8, a ridging device bracket 102, and a press wheel bracket 103, all of which have lifting and adjusting functions. The bottom end of the ridging device bracket 102 is provided with a pair of notched harrow blades 9, and the bottom end of the press wheel bracket 103 is provided with a press wheel 10. The axial length of the press wheel 10 is adapted to the width of a single tillage strip. Along the traveling direction of the mounting frame 1, the deep tillage shovel 8, the notched harrow blades 9, and the press wheel 10 are arranged sequentially from front to back.

[0055] The deep loosening shovel 8 is used for deep loosening of the soil after straw removal. For example... Figure 7 As shown, the subsoil shovel 8 includes a handle 81 and a tip 82. An opening is provided at the rear bottom of the handle 81, and a sliding plug 83 is installed inside the opening. Sliding the plug 83 downwards fixes the tip 82, while sliding it upwards releases the tip 82, allowing for flexible replacement of tips 82 of different sizes to meet various subsoil requirements. The specific replacement structure and method are well known to those skilled in the art; this embodiment only provides a brief description and does not elaborate further.

[0056] A pair of notched rake blades 9 has two notched rake blades 9. The rotation plane of the notched end of the notched rake blade 9 maintains an angle of 0 to 20° with the working direction. That is, the two notched rake blades 9 form a structure with a large opening at the front end and a small opening at the rear end, which can gather the soil after deep loosening and make the soil after deep loosening gather into a miniature ridge.

[0057] The compaction roller 10 is used to break up and compact the soil, ultimately forming a flatter, more compacted strip than a typical micro-ridge. This ensures the soil remains loose while still being exposed to the environment, increasing the contact area and allowing the soil to receive more sunlight and air. In a specific example, the micro-ridges formed after being compacted by the roller 10 are approximately 180mm wide and 60mm high. Depending on the soil moisture, the compaction roller 10 can be either a toothed roller or a compression roller. Figure 13 , Figure 14 As shown.

[0058] like Figure 15As shown, in this embodiment, the center surfaces of the rotating component, the subsoil shovel 8, the two notched rake blades 9, and the press wheel 10 are as close to a straight line as possible, meaning that the same tillage strip is processed sequentially. In this embodiment, the subsoil shovel 8, the ridging device bracket 102, and the press wheel bracket 103 are all vertically adjustable. As a specific example, in this embodiment, the mounting bracket has multiple first mounting holes arranged from top to bottom at the positions corresponding to the mounting of the subsoil shovel 8, the ridging device bracket 102, and the press wheel bracket 103; correspondingly, the handle 81 of the subsoil shovel 8, the ridging device bracket 102, and the press wheel bracket 103 are all provided with multiple second mounting holes. In use, the alignment of the first and second mounting holes is adjusted, and then bolts are passed through the first and second mounting holes, and finally, nuts are used to secure them.

[0059] like Figure 6 As shown, the mounting frame 1 includes a four-bar linkage 11 for detachable connection with the traction equipment or traction frame 2. The four-bar linkage 11 includes a front mounting plate 1101, a rear mounting plate 1102, and a compression spring 1103. The front mounting plate 1101 is used for detachable connection with the traction equipment or traction frame 2. As an example of a connecting plate, the front mounting plate 1101 is provided with multiple through holes. The crossbeam of the traction equipment or traction bracket is locked using U-shaped fasteners. The two ends of the U-shaped fasteners pass through two through holes on the front mounting plate 1101 and are then tightened with nuts. The front mounting plate 1101 has flanges on both sides, and the top of the front mounting plate 1101 is connected to the top plate 1104. An upper rotating shaft 1105 and a lower rotating shaft 1106 are provided between the two flanges. An upper connecting rod 1107 and a lower connecting rod 1108 are respectively fixed to the upper rotating shaft 1105 and the lower rotating shaft 1106. The ends of the upper connecting rod 1107 and the lower connecting rod 1108 are hinged to the rear mounting plate 1102, which is fixedly connected to the main beam plate 101. As an example, there are two upper connecting rods 1107 and two lower connecting rods 1108. The lower connecting rod 1108 is connected to a connecting shaft 1109 via a connecting shaft. The top end of the connecting shaft 1109 passes through the top plate 1104, and a compression spring 1103 is sleeved on the connecting shaft 1109. The top and bottom ends of the compression spring 1103 are fixed to the top plate 1104 and the connecting shaft, respectively. The rotating component 5 is rotatably connected to the rotating component mounting plate 104, which is fixedly connected to the rear mounting plate 1102 via a connecting plate. Both the rear mounting plate 1102 and the rotating component mounting plate 104 are provided with a first mounting hole and a second mounting hole, respectively, allowing adjustment of the height of the rotating component 5. Simultaneously, an arc-shaped baffle 105 is detachably connected to the rotating component mounting plate 104 via bolts. The arc-shaped baffle 105 is located above the rotating component 5 and can block any straw that is lifted from above. The side wall of the arc-shaped baffle 105 also has an arc-shaped slot; bolts pass through these slots and are fixedly connected to the rotating component mounting plate 104, allowing adjustment of the position of the arc-shaped baffle 105 along the arc-shaped trajectory of the slot.

[0060] By setting up a four-bar linkage 11, the rotating part 5, the deep loosening shovel 8, the notched rake blade 9, and the press wheel 10 move up and down on the undulating surface, and the compression spring 1103 overcomes the undulating energy and plays a role in vibration reduction.

[0061] In this embodiment, the input shaft 6 is also fixed to the flange of the front mounting plate 1101 by bearings.

[0062] Example 2:

[0063] like Figure 1 , Figure 2 As shown, this embodiment provides a strip tillage machine, including a traction frame 2 and at least one strip tillage device as described in Embodiment 1, fixed on the traction frame 2. If there is one strip tillage device, the input shaft 6 is drivenly connected to the output end of the drive mechanism. If there are two or more strip tillage devices, at least one input shaft 6 is drivenly connected to the output end of the drive mechanism, and the input shafts 6 of adjacent strip tillage devices are connected by couplings. As a specific implementation, a gearbox 3 is fixed on the traction frame 2. The input end of the gearbox 3 is used for drive-through connection with the power output of the traction equipment, and the output end of the gearbox 3 is drivenly connected to the input shaft 6 of the strip tillage machine. Specifically, this connection can be achieved through couplings to realize power transmission.

[0064] In one embodiment, contour wheels 4 are installed at both ends of the traction frame 2, and one or more strip tillage devices are arranged between the two contour wheels 4.

[0065] Any adaptive changes made according to actual needs are within the scope of protection of this invention.

[0066] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
