Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to a rotary tillage and ridging machine for cotton plants. Background Technology

[0002] In the early stages of cotton seedling growth, cotton plants may be stunted and grow poorly. Salt and alkalinity and low temperatures are among the reasons for this. In order to slow down the upward movement of salt and alkali in cotton fields, increase soil temperature, enhance cotton root vitality, promote early seedling growth, and ensure robust and uniform seedling development, soil is usually mounded around the cotton seedlings. In the past, soil mounding was mostly done manually, which was inefficient, time-consuming, and labor-intensive. Therefore, a rotary tiller soil mounding machine that can effectively and automatically mound soil around multiple rows of seedlings at the same time has been developed.

[0003] CN218042457U discloses a rotary tiller for sealing cotton plants, comprising a frame connected to a tractor. The frame is equipped with a traveling device, a power transmission device, rotary tillers located on both sides of the frame, a conveying device, and a diverting device. The power transmission device is driven by the tractor's power unit, and is driven by the rotary tillers. The rotary tillers are driven by the conveying device. The tractor pulls the frame, which moves via the traveling device. This design is reasonable, highly automated, and capable of sealing multiple rows of seedlings with good results. While the rotary tillers described above are suitable for relatively flat terrain, in actual use, the terrain is often complex, and the effect of sealing is poor on uneven surfaces. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, this utility model provides a rotary tillage and ridging machine for cotton plants.

[0005] A rotary tillage and ridging machine for cotton plants includes a frame, on which:

[0006] A rotary tillage mechanism, comprising a plurality of rotary tillage blades, which are circumferentially distributed on the blade holder with the blade holder's pivot as the center. The pivot is equipped with a power source that drives the blade holder to adjust its height in the vertical direction, so that the rotary tillage blades can perform rotary tillage at different heights.

[0007] A conveying mechanism, the conveying mechanism including a conveying bucket for receiving and conveying rotary tilled soil;

[0008] The dispersing mechanism includes a vibrating dispersing screen, which disperses large particles of rotary tillage through vibration. Small particles of rotary tillage fall through the gaps in the dispersing screen into several inclined hilling channels and then onto the cotton seedlings. Rotary tillage that cannot be dispersed rolls down the surface of the inclined dispersing screen into a distribution cylinder and then falls into the rows of cotton seedlings.

[0009] Furthermore, the conveying bucket is mounted on a chain conveyor belt, which is connected to a conveyor sprocket, and the conveyor sprocket is rotatably mounted on the frame via a drive shaft.

[0010] Furthermore, the frame is also equipped with a power mechanism, which includes a gearbox. The gearbox is connected to the rotating shaft and the drive shaft via a universal joint structure.

[0011] Furthermore, the inclined support plate of the conveying bucket is provided with an extension plate, which is made of a flexible material.

[0012] Furthermore, the two ends of the drive shaft connected to the top conveyor sprocket extend out of the frame and are connected to the turntable. The turntable is connected to the drive linkage via an eccentric shaft. The drive linkage is rotatably connected to the screen handle of the dispersing screen. The screen handle is also rotatably connected to the drive linkage, which is rotatably mounted on the frame.

[0013] Furthermore, the dispersing screen is provided with a guide plate on the side near the conveying hopper, and the guide plate is mounted on the frame by mounting rollers.

[0014] Furthermore, a baffle plate is provided on the side of the dispersing screen away from the conveying hopper on the frame, and the baffle plate is located above the diverting cylinder.

[0015] Furthermore, both ends of the rotating shaft are provided with sliders, which are slidably connected to the frame in the vertical direction. The sliders are connected to the output of the hydraulic cylinder, which is fixedly mounted on the frame.

[0016] Furthermore, the bottom of the frame is provided with casters for movement.

[0017] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are:

[0018] 1. In this utility model, the rotary tiller blades are distributed circumferentially on the blade holder with the blade holder's rotation axis as the center. The blade holder can be height adjusted, which makes it convenient for the operator to adjust the rotary tiller height according to the land conditions, effectively improving the soil-laying effect. The device has high applicability.

[0019] 2. In this utility model, the dispersing mechanism breaks up large particles of rotary tilled soil through vibration, and small particles of rotary tilled soil fall through several hilling channels at a certain angle. The hilling channels with different inclination angles correspond to different rows of cotton seedlings, thereby realizing the hilling of multiple rows of cotton seedlings at one time, which improves the efficiency of hilling. Large particles of rotary tilled soil that are not broken up roll down the surface of the dispersing screen into the dispersing cylinder and fall into the spaces between the cotton rows, preventing large particles of rotary tilled soil from pressing on the cotton plants and affecting their normal growth.

[0020] 3. In this utility model, the inclined support plate of the conveying bucket is provided with an extension plate. The extension plate is made of flexible material. On the one hand, the extension plate can effectively increase the amount of rotary tillage soil that the conveying bucket can hold. On the other hand, if there are large clods of soil or stones at the support of the extension plate, the extension plate will bend and fall out from the gap between the frame and the conveying bucket. The bending of the extension plate can increase the space for the clods of soil and stones to fall, thereby avoiding wear and tear on the frame when the clods of soil and stones fall.

[0021] 4. In this utility model, the gearbox is connected to the rotating shaft and the transmission shaft through a universal joint structure, thereby driving the rotary tillage mechanism, the conveying mechanism and the dispersing mechanism to work. The structure is stable and reliable. Attached Figure Description

[0032] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0033] according to Figure 1-9 As shown, a rotary tillage and ridging machine for cotton plants includes a frame 1, on which:

[0034] Rotary tillage mechanism 2, the rotary tillage mechanism 2 includes a plurality of rotary tillage blades 21, the plurality of rotary tillage blades 21 are circumferentially distributed on the blade holder 22 with the rotating shaft 23 as the center, the rotating shaft 23 is equipped with a power source that drives the blade holder 22 to adjust its height in the vertical direction, so that the rotary tillage blades 21 can perform rotary tillage at different heights;

[0035] Conveying mechanism 3, the conveying mechanism 3 includes a conveying bucket 31 for receiving and conveying rotary tilled soil;

[0036] The dispersing mechanism 4 includes a vibrating dispersing screen 41, which disperses large particles of rotary tillage through vibration. Small particles of rotary tillage fall through the gaps in the dispersing screen 41 into several inclined hilling channels 5, and then fall onto the cotton seedlings along the hilling channels 5. Rotary tillage that cannot be dispersed rolls down the surface of the inclined dispersing screen 41 into the diversion cylinder 6, and then falls into the spaces between the rows of cotton seedlings along the diversion cylinder 6.

[0037] In the above-mentioned specific technical solution, the rotary tillage mechanism 2 uses the rotation of the rotary tillage blades 21 to till the soil and send it into the conveying bucket 31. The operator can control the tillage height of the rotary tillage blades 21 according to the ground conditions, which effectively improves the soil covering effect. The device has high applicability. The conveying bucket 31 transports the tilled soil from the bottom to the top. After passing through the dispersing mechanism 4, the large particles of tilled soil are broken up by vibration. The small particles of tilled soil fall through several soil covering channels 5 with a certain angle. The soil covering channels 5 with different angles of inclination correspond to different rows of cotton seedlings, thereby realizing the soil covering of multiple rows of cotton seedlings at one time, which improves the soil covering efficiency. The large particles of tilled soil that are not broken up roll down the surface of the dispersing screen 41 into the distribution cylinder and fall into the cotton rows, preventing the large particles of tilled soil from pressing on the cotton plants and affecting the normal growth of the cotton plants.

[0038] Preferably, two sets of rotary tillage mechanism 2, conveying mechanism 3 and dispersing mechanism 4 are provided, which further increases the soil-raising efficiency of the device.

[0039] according to Figure 4 As shown, the conveyor bucket 31 is mounted on the chain conveyor belt 32, which is connected to the conveyor sprocket 33. The conveyor sprocket 33 is rotatably mounted on the frame 1 via the drive shaft 34. Several conveyor buckets 31 are equidistantly mounted on the conveyor chain. The chain conveyor belt 32 transports the rotary tilled soil from the bottom to the top of the frame 1. Through the continuous rotation of the rotary tiller blades 21, the chain conveyor belt 32 continuously transports the rotary tilled soil to the hilling channel 5 via the conveyor buckets 31, thereby ensuring the normal progress of the hilling work.

[0040] according to Figure 3 and Figure 6 As shown, the frame 1 is also provided with a power mechanism 7, which includes a gearbox 71. The gearbox 71 is connected to the rotating shaft 23 and the drive shaft 34 through a universal joint structure 72.

[0041] according to Figure 4 and Figure 7 As shown, the two ends of the transmission shaft 34 connected to the top conveyor sprocket 33 extend out of the frame 1 and are connected to the turntable 42. The turntable 42 is connected to the drive linkage 44 through the eccentric shaft 43. The drive linkage 44 is rotatably connected to the screen handle 411 of the dispersing screen 41. The screen handle 411 is also rotatably connected to the transmission linkage 45. The transmission linkage 45 is rotatably mounted on the frame 1.

[0042] In the above specific technical solution, the power source for the rotary tillage mechanism 2, the conveying mechanism 3, and the dispersing mechanism 4 is the gearbox 71. The output end of the gearbox 71 is connected to the first connecting shaft of the universal joint structure 72. Both ends of the first connecting shaft are equipped with universal joint chains, which are connected to the rotating shafts 23 of the two sets of rotary tillage mechanisms 2. The universal joint chains drive the rotating shafts 23 to rotate, thereby driving the rotary tillage blades 21 on the blade holder 22 to rotate. The first connecting shaft is connected to the second drive shaft 34 through a sprocket and chain mechanism. The second drive shaft 34 is rotatably mounted on the frame 1. Both ends of the second drive shaft 34 are connected to the drive shafts 34 at the bottom of the two sets of conveying mechanisms 3 through universal joint chains, thereby driving the bottom conveyors. The sprocket 33 rotates, and the conveyor sprocket 33 drives the chain conveyor belt to move, thereby realizing the cyclic conveying of rotary tilled soil by the conveyor bucket 31. The top conveyor sprocket 33 drives the turntable 42 to rotate by rotating. The eccentric shaft 43 drives one end of the drive connecting rod 44 to rotate. The other end of the drive connecting rod 44 is rotatably connected to the screen handle 411 of the dispersing screen 41. The screen handle 411 is rotatably connected to the transmission connecting rod 45, thereby causing the dispersing screen 41 to swing within a certain range and be in a vibrating state. The vibrating dispersing screen 41 can achieve the effect of dispersing large particles of rotary tilled soil. Rotary tilled soil and stones that cannot be dispersed fall into the diversion cylinder along the inclined dispersing screen 41. Furthermore, the dispersing screen 41 can also serve as a filter for the mulch film.

[0043] It is worth noting that by using the universal joint structure 72 to replace the sprocket and chain mechanism for driving the rotary tillage mechanism 2, the conveying mechanism 3, and the dispersing mechanism 4, the stability of the transmission can be increased. Compared with driving entirely through the chain and sprocket mechanism, the possibility of the chain links getting stuck on the mulch film is reduced.

[0044] according to Figure 4 and Figure 5 As shown, the inclined support plate of the conveying bucket 31 is provided with an extension plate 311. The extension plate 311 is made of flexible material. The extension plate 311 can effectively increase the amount of rotary tillage soil that the conveying bucket 31 can hold. Preferably, the extension plate 311 can be made of rubber. If there are large clods of soil or stones at the support of the extension plate 311, their weight will cause the extension plate 311 to bend and fall out of the gap between the frame 1 and the conveying bucket 31. The bending of the extension plate 311 can increase the space for the clods of soil and stones to fall, thereby avoiding wear on the frame 1 when the stones and soil fall. Furthermore, the extension plate 311 is fixedly installed on the inclined support plate by bolts, which is convenient to install and easy to replace.

[0045] according to Figure 4 and Figure 8 As shown, the dispersing screen 41 is provided with a guide plate 46 on the side near the conveying bucket 31. The guide plate 46 is mounted on the frame 1 by the mounting roller 47. The guide plate 46 guides the rotary tilled soil, so that the rotary tilled soil flying out of the conveying bucket falls onto the dispersing screen 41.

[0046] As shown in body 4, a baffle plate 8 is provided on the side of the dispersing screen 41 away from the conveying hopper 31 on the frame 1. The baffle plate is located above the diversion cylinder 6 to prevent the rotary soil in the conveying hopper 31 from falling directly into the diversion cylinder 6 and to block the rotary soil.

[0047] according to Figure 1 and Figure 9 As shown, both ends of the rotating shaft 23 are equipped with sliders 24. The sliders 24 are slidably connected to the frame 1 in the vertical direction. The sliders 24 are connected to the output of the hydraulic cylinder 25. The hydraulic cylinder 25 is fixedly installed on the frame 1. The frame 1 is provided with a slide rail that cooperates with the sliders 24. Activating the hydraulic cylinder 25 can drive the sliders 24 to move in the vertical direction. The movement of the sliders 24 drives the blade holder 22 to move in the vertical direction. The operator can raise and lower the blade holder 22 according to the terrain conditions, thereby controlling the tillage height of the rotary tiller 21. This ensures the soil-laying effect when the device faces complex terrain conditions, increasing the applicability of the device.

[0048] The bottom of the frame 1 is provided with rollers 9 for movement, which enables the frame 1 to move.
