Description

Technical Field

[0001] This utility model relates to a multifunctional rotary tillage and ridging machine that removes film and covers soil, belonging to the field of rotary tillage and film removal technology for tobacco fields. Background Technology

[0002] In tobacco cultivation, mulch film is often used to cover the ridges, and it needs to be removed and recycled during the field management stage. Existing literature (CN220369180U) discloses a rotary tiller-type mulch film removal machine, comprising: a rotary tiller frame with handles; a power mechanism mounted on the rotary tiller frame; a walking mechanism including a housing, a first transmission mechanism, and walking wheels, the housing being located at the bottom of the rotary tiller frame; one end of the first transmission mechanism being connected to the power mechanism, and the other end connected to a rotating shaft, with walking wheels connected to both sides of the rotating shaft; and a mulch film removal mechanism including a mulch film removal frame, a mulch film removal shaft, a second transmission mechanism, and a mulch film removal cylinder. The mulch film removal frame is located at the top of the rotary tiller frame, the mulch film removal shaft is rotatably mounted laterally on the mulch film removal frame, the second transmission mechanism connects the mulch film removal shaft to the rotating shaft, and the mulch film removal cylinder is detachably mounted at both ends of the mulch film removal shaft. This solution combines an existing small hand-held rotary tiller with a mulch film removal component, enabling rapid and labor-saving removal and recycling of mulch film in tobacco fields. However, the applicant found at least the following problems in actual production: First, the current film-removing machine can only perform the film-removing function and cannot simultaneously perform the rotary tillage and soil-covering function; second, the walking wheels often slip during the film-removing process, while the film-removing drum rotates normally, which causes the film-removing drum to pull the film and affect the normal film-removing and winding work; third, the current film-removing drum has two drums, which is not convenient to operate, especially when turning or making a U-turn. Utility Model Content

[0003] Based on the above, this utility model provides a multi-functional rotary tillage and ridging machine with film removal function to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a multi-functional rotary tillage and hilling machine for removing film, weeding, and cultivating, comprising:

[0005] A rotary tillage assembly includes a rotary tillage frame, a power mechanism mounted on the rotary tillage frame, a first transmission mechanism connected to the power mechanism, and rotary tillage blades connected to the first transmission mechanism.

[0006] The soil-raising assembly includes two detachable grooving plates installed at the bottom of the rotary tiller and behind the rotary tiller blades. The grooving plates are connected together at an acute angle, and the connection between the two grooving plates is inclined backward from top to bottom. Each grooving plate is inclined inward from top to bottom, and each grooving plate has an inward curved arc shape from the middle to the rear.

[0007] The film-removing assembly includes a film-removing frame mounted on top of the rotary tiller, a film-removing shaft rotatably mounted on the film-removing frame, film-removing cylinders mounted at both ends of the film-removing shaft, and a second transmission mechanism mounted between the first transmission mechanism and the film-removing shaft.

[0008] In one example, the first transmission mechanism includes a worm gear mechanism and a rotating shaft. The worm gear mechanism includes a worm and a worm wheel that mesh with each other. The worm is connected to the output shaft of the power mechanism. The rotating shaft is connected to the worm wheel. Both ends of the rotating shaft extend to both sides of the rotary tiller, and the rotary tiller blades are mounted on the rotating shaft.

[0009] In one example, the second transmission mechanism includes a drive sprocket, a driven sprocket, and a transmission chain. The drive sprocket is mounted on the rotating shaft and is a multi-stage sprocket. The driven sprocket is mounted on the film-removing shaft, and the transmission chain connects the drive sprocket and the driven sprocket.

[0010] In one example, a speed regulating mechanism is installed on the second transmission mechanism, the speed regulating mechanism including a chain deflector and a controller, the chain deflector being installed on the film-unwrapping frame and the transmission chain passing through the chain deflector, the controller being installed on the handle of the rotary tiller, the controller being used to control the movement of the chain deflector.

[0011] In one example, a mudguard is provided on the lower side of the rotary tiller, outside the drive sprocket and the conveyor chain.

[0012] In one example, the soil-building component is mounted on the rotary tiller via an installation mechanism comprising a horizontal bar, a longitudinal bar, and a vertical bar. The horizontal bar is located in the middle of the two scraper plates, and the longitudinal bar connects the horizontal bar to the inner side of the scraper plate. The front end of the horizontal bar has a first mounting hole, and the rear end of the horizontal bar has a second mounting hole. The vertical bar is detachably mounted in the second mounting hole. The rotary tiller is provided with an installation rod, which is mounted in the first mounting hole.

[0013] In one example, there is one film-removing cylinder, and a film guide frame is provided on each of the two front sides of the rotary tiller. A film guide disc is provided on the film guide frame, and the film guide disc is located above the top of the ridge.

[0014] In one example, the guide plate includes a disc shaft rotatably mounted on the guide plate frame, and disc bodies mounted on both sides of the disc shaft.

[0015] The beneficial effects of this invention are as follows: By replacing the traveling wheels with rotary tillers and installing two scraper blades behind the rotary tillers, the tiller can simultaneously perform rotary tillage, weeding, and loosening of the soil in the furrows during travel. The scraper blades then guide the soil onto the ridges on both sides, thus achieving rotary tillage, weeding, and hilling functions. Furthermore, the speed-regulating mechanism allows for adjustment of the film-lifting shaft's rotation speed, thereby regulating the film-lifting cylinder's rotation speed. This prevents the rotary tillers from slipping while the film-lifting cylinder rotates normally, which could pull on the mulch film and affect normal winding. By using a single film-lifting cylinder and placing guide discs on both sides in front of the rotary tiller frame, the film-lifting cylinder can lift the mulch film upwards, avoiding scratching the tobacco seedlings by pulling it at an angle. The mulch film is also wound into the same film-lifting cylinder. Compared to a structure with one film-lifting cylinder on each side of the film-lifting frame, this structure is more convenient for the rotary tiller's operation. Attached Figure Description

Detailed Implementation

[0028] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] Please see Figures 1 to 5 This embodiment provides a multi-functional rotary tillage and ridging machine with film removal, which includes a rotary tillage component, a ridging component, and a film removal component.

[0030] The rotary tillage assembly includes a rotary tiller frame 11, a power mechanism 12 mounted on the rotary tiller frame 11, a first transmission mechanism 13 connected to the power mechanism 12, and rotary tillage blades 14 connected to the first transmission mechanism 13. The power mechanism 12 can be a gasoline engine. The first transmission mechanism 13 includes a worm gear mechanism 131 and a rotating shaft 132. The worm gear mechanism 131 includes a meshing worm and a worm wheel. The worm is connected to the output shaft of the power mechanism 12. The rotating shaft 132 is connected to the worm wheel, and both ends of the rotating shaft 132 extend to both sides of the rotary tiller frame 11. The rotary tillage blades 14 are mounted on the rotating shafts 132 on both sides. The rotary tillage blades 14 are conventional blades. During operation, the gasoline engine drives the worm, worm wheel, and rotating shaft 132 to rotate, thereby driving the rotary tillage blades 14 to rotate. The worm gear mechanism 131 is common knowledge in the art and will not be described in detail.

[0031] The ridging assembly includes two detachable scraper blades 21 mounted on the bottom of the rotary tiller 11 and behind the rotary tiller blades 14. The scraper blades 21 are connected at an acute angle, and the connection point of the two scraper blades 21 slopes backward from top to bottom. Each scraper blade 21 slopes inward from top to bottom, and each scraper blade 21 has an inward curved arc shape from the middle to the rear. As the scraper blades 21 move forward with the rotary tiller 11, they can scrape the soil in the furrows to both sides. At the same time, because the middle and rear parts of each scraper blade 21 have an inward curved arc shape, compared with a shape without an inward curved arc, the soil can be guided to a higher position on the ridge surface, resulting in better effect.

[0032] The film-removing assembly includes a film-removing frame 31 mounted on top of the rotary tiller 11, a film-removing shaft 32 rotatably mounted on the film-removing frame 31, film-removing cylinders 33 mounted at both ends of the film-removing shaft 32, and a second transmission mechanism 34 installed between the first transmission mechanism 13 and the film-removing shaft 32. The second transmission mechanism 34 is used to transmit the power of the first transmission mechanism 13 to the film-removing shaft 32, thereby driving the film-removing cylinders 33 to rotate. The second transmission mechanism 34 includes a drive sprocket 341, a driven sprocket 342, and a transmission chain 343. The drive sprocket 341 is mounted on the rotating shaft 132, the driven sprocket 342 is mounted on the film-removing shaft 32, and the transmission chain 343 connects the drive sprocket 341 and the driven sprocket 342.

[0033] For ease of operation, a speed regulating mechanism is installed on the second transmission mechanism 34. This mechanism includes a chain deflector 344 and a controller 345. The chain deflector 344 is mounted on the film-removing frame 31, and the transmission chain 343 passes through the chain deflector 344. The drive sprocket 341 is a multi-stage sprocket. The controller 345 is mounted on the handle of the rotary tiller 11. The controller 345 controls the movement of the chain deflector 344, thereby changing the position of the transmission chain 343 on the multi-stage sprocket, thus changing the rotational speed of the film-removing shaft 32 relative to the rotating shaft 132. When the rotary tiller blades 14 are moving and tilling the soil in the furrows, they may slip. In this case, the rotating shaft 132 will still transmit power to the film-removing shaft 32 through the second transmission mechanism 34, causing the film-removing cylinder 33 to rotate and pull the film. By setting up the speed regulating mechanism, the rotational speed of the film-removing shaft 32 can be adjusted as needed, thereby adjusting the rotational speed of the film-removing frame 31. This can prevent the problem of the rotary tiller blades 14 slipping while the film-removing cylinder 33 rotates normally, causing it to pull the film and affecting the normal winding and harvesting work. The controller 345 can be a manual lever or a knob.

[0034] To prevent splashed mud from hitting the conveyor chain 343 and affecting its normal operation, a mud guard 15 is installed on the lower side of the rotary tiller 11, on the outside of the drive sprocket 341 and the conveyor chain 343.

[0035] For ease of operation, the soil-raising component is installed on the rotary tiller 11 via an installation mechanism. The installation mechanism includes a horizontal bar 22, a longitudinal bar 23, and a vertical bar 24. The horizontal bar 22 is located in the middle of the two scraper plates 21. The longitudinal bar 23 connects the horizontal bar 22 to the inner side of the scraper plate 21. The front end of the horizontal bar 22 is provided with a first mounting hole 25, and the rear end of the horizontal bar 22 is provided with a second mounting hole 26. The vertical bar 24 is detachably installed in the second mounting hole 26. The rotary tiller 11 is provided with an installation rod 27, which is installed in the first mounting hole 25, thereby installing the scraper plate 21 on the rotary tiller 11.

[0036] For ease of operation, there is only one film-removing cylinder 33, which is mounted in the middle of the film-removing frame 31. A guide film frame 35 is located on each side in front of the rotary tiller 11, and a guide film disc 36 is mounted on each guide film frame 35. The guide film disc 36 is positioned above the top of the ridge. The guide film disc 36 includes a disc shaft 361 rotatably mounted on the guide film frame 35, and disc bodies 362 mounted on both sides of the disc shaft 361. When removing the film, as the guide film disc 36 moves forward with the rotary tiller 11, the mulch film on the ridge surface enters the film-removing cylinder 33 through the corresponding guide film disc 36. Because the guide film disc 36 is located directly above the ridge, it can lift the mulch film upwards, avoiding scratching the tobacco seedlings by pulling the mulch film at an angle. Furthermore, the mulch film is rolled up in the same film-removing cylinder 33. Compared to a structure with one film-removing cylinder 33 on each side of the film-removing frame 31, this structure is more convenient for the rotary tiller's operation.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
