Description

Technical Field

[0001] This invention relates to a machine for integrated film-covering and soil-breaking at fixed points, belonging to the field of film-covered transplanting technology for tobacco fields. Background Technology

[0002] Currently, before transplanting flue-cured tobacco, the process typically involves three steps: land preparation and ridging, mulching, and perforation and soil covering. Land preparation and ridging refers to leveling and refining the tobacco planting area using appropriate land treatment methods, creating a standardized ridging management model. The aim is to improve planting efficiency, reduce pests and diseases, promote crop growth, improve tobacco quality, and increase farmers' income. Mulching refers to covering the soil surface with agricultural plastic film, a crop yield-increasing cultivation measure that retains heat, moisture, and soil, increases yield, and reduces weeds. Perforation and soil covering involves making openings in the mulched tobacco ridges according to the transplanting plant spacing, covering the openings with soil, and compacting the soil to create a butterfly shape. Perforation and soil covering during transplanting can alleviate moisture evaporation from the mulch openings, prevent excessive weed growth, reduce slug damage, and promote early and rapid growth of tobacco plants. Currently, Current mulching machines mechanically apply mulch material to the surface of farmland to form a protective film. They typically consist of a mulching machine and a mobile platform. The mulching machine spreads the mulch material, while the mobile platform moves it to the desired location. The mulching machine then begins the mulching process, with soil continuously being expelled from the mulching inlet to compact the film. Finally, a cutting blade cuts the film, completing the ridging and mulching operation in one operation. This mechanized method significantly improves the efficiency and quality of mulching. However, current mulching machines can only apply the film and do not yet have a hole-punching function, making them unsuitable for integrated tobacco farming operations. Summary of the Invention

[0003] Based on the above, the present invention provides an integrated machine for fixed-point film breaking and soil covering to overcome the shortcomings of the prior art.

[0004] The technical solution of this invention is: a machine for integrated film covering and soil breaking, comprising: A mobile unit includes a frame, a first gasoline engine mounted on the frame, a traveling wheel mounted on the frame, and a transmission component connecting the first gasoline engine and the traveling wheel, the transmission component having a first transmission wheel; The film breaking unit includes a second drive wheel rotatably mounted on the frame, a crank rocker arm mechanism connected to the second drive wheel, a film breaking rod mounted on the crank rocker arm mechanism, and a drill mechanism mounted on the film breaking rod. A drive chain is installed between the second drive wheel and the first drive wheel. The film covering unit includes a film cylinder frame, a film pressing wheel, and a soil guiding wheel, which are installed sequentially from front to back under the vehicle frame and in front of the drill mechanism, with the film pressing wheel and the soil guiding wheel located on both sides of the vehicle frame.

[0005] In one example, the frame includes a flat frame, a handlebar mounted at the rear end of the flat frame, a vertical frame mounted in the middle of the flat frame, and a U-shaped frame mounted at the front end of the flat frame.

[0006] In one example, the output shaft of the first gasoline engine is provided with a third drive wheel, the transmission component has a fourth drive wheel, and a drive belt is installed between the third drive wheel and the fourth drive wheel.

[0007] In one example, the second drive wheel is rotatably mounted on the upper part of the vertical frame via the drive shaft. The crank rocker arm mechanism includes a first connecting rod fixedly connected to the radial direction of the drive shaft, a second connecting rod hinged to the lower part of the vertical frame, and a third connecting rod hinged to the first and second connecting rods respectively. The third connecting rod is provided with a mounting plate, and the rupture rod is fixed to the mounting plate by fasteners.

[0008] In one example, the drill bit mechanism includes an upper plate, a lower plate, a drill bit shaft, a cutting disc, a swirling disc, a mudguard, a first spring, a first movable rod, a second gasoline engine, a flexible shaft, and a transmission mechanism. The upper plate is fixed to the bottom of the cutting rod, and the lower plate is connected to the lower part of the upper plate via a fixed rod. The drill bit shaft is rotatably mounted on the lower plate. The cutting disc and the swirling disc are mounted sequentially from bottom to top on the drill bit shaft. The swirling disc is a spiral disc. The mudguard is connected to the lower part of the upper plate via multiple springs and the first movable rod. The bottom of the first movable rod is fixed to the mudguard, and the top of the first movable rod moves through the upper plate. The first spring is sleeved on the first movable rod. The mudguard surrounds the cutting disc and the swirling disc. The second gasoline engine is mounted on the frame and is connected to the transmission mechanism via a flexible shaft. The transmission mechanism is connected to the drill bit shaft.

[0009] In one example, a second movable rod is installed on both sides of the bottom of the vertical frame, the bottom of the second movable rod is provided with a pressure roller, and a second spring is sleeved on the second movable rod.

[0010] In one example, the U-shaped frame includes an upper horizontal bar, a lower horizontal bar, a vertical member, and a middle connecting rod. The upper horizontal bar is located at the front end of the flat frame, the lower horizontal bar is connected to the lower part of the upper horizontal bar via the middle connecting rod, the vertical member is connected to both ends of the upper and lower horizontal bars, and the traveling wheel is mounted on the side of the vertical member.

[0011] In one example, an adjusting rod is connected to the top center of the membrane tube frame. The adjusting rod is mounted on a horizontal rod that can be adjusted up and down. The horizontal rod is fixedly connected to the intermediate connecting rod.

[0012] In one example, the adjusting rod is equipped with a curved rod extending rearward and downward, the lower end of which is connected to a roller frame, on which a pressure roller is mounted, and arc-shaped rods are mounted on both sides of the roller frame, with the pressure roller located at the rear and lower part of the film cylinder frame.

[0013] In one example, the pressure roller and the guide roller are mounted on a longitudinal rod via a bracket, the front end of which is adjustablely mounted on a longitudinal bend rod, and the front end of which is adjustablely mounted on a lower crossbar.

[0014] The beneficial effects of this invention are as follows: During mulching, the mulch film is installed on the film film frame of the installation device, the vehicle frame is placed on one side of the ridge, and the traveling wheels are located in the furrows on both sides. As the vehicle frame moves forward, the mulch film is first released onto the ridge surface, while the mulch film on both sides is pressed down by the film pressing wheels, and the soil in the furrows is guided by the soil guide wheels to cover and fix the mulch film. At the same time, under the power transmission of the first drive wheel, the second drive wheel, and the drive chain, the crank rocker arm mechanism swings back and forth, simultaneously drilling holes and covering the soil while driving the drill bit shaft to drill downwards into the soil. In addition, the mudguard first presses on the mulch film during drilling, then compresses the first spring, while the drill bit shaft continues downwards, the film cutting blade cuts the mulch film and drills holes in the soil. During the drilling process, the soil rotating blade rotates the soil upwards and throws it out in all directions. The thrown soil falls onto the mulch film between the mudguard and the soil rotating blade under the blocking effect of the mudguard, thereby realizing the mulching operation and avoiding soil splashing, while forming a regular saucer-shaped transplanting opening on the film.

[0015] This equipment seamlessly integrates the two processes of mulching and fixed-point soil covering, moving the soil filling and sealing operation forward, effectively alleviating the labor shortage problem in this stage, and providing convenience for subsequent transplanting operations, making transplanting more efficient and accurate. It improves the level of mechanized operations in tobacco fields, increases operational efficiency, reduces production labor, lowers labor costs, and lays the foundation for achieving full mechanization.

[0017] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced 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 the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Please see Figures 1 to 7 This embodiment describes a film-covering and fixed-point film-breaking and soil-covering integrated machine, which includes a moving unit, a film-breaking unit, and a film-covering unit.

[0019] The mobile unit includes a frame 11, a first gasoline engine 12 mounted on the frame 11, a running wheel 13 mounted on the frame 11, and a transmission component 14 connecting the first gasoline engine 12 and the running wheel 13, the transmission component 14 having a first transmission wheel 15.

[0020] In one example, the frame 11 includes a flat frame 111, a handrail 112 mounted at the rear end of the flat frame 111, a vertical frame 113 mounted in the middle of the flat frame 111, and a U-shaped frame 114 mounted at the front end of the flat frame 111. The first gasoline engine 12 can be a 7.5 horsepower gasoline engine, which is located at the rear of the frame 11. The output shaft of the first gasoline engine 12 is provided with a third drive wheel 18, and the transmission component 14 has a fourth drive wheel 16. A transmission belt 17 is installed between the third drive wheel 18 and the fourth drive wheel 16, so that power is transmitted to the transmission component 14 through the third drive wheel 18, the fourth drive wheel 16 and the transmission belt 17, and then the rotating component drives the traveling wheel 13 to rotate. The transmission component 14 is common knowledge in the art and will not be described in detail here.

[0021] The film breaking unit includes a second drive wheel 21 rotatably mounted on the frame 11, a crank rocker arm mechanism 23 connected to the second drive wheel 21, a film breaking rod 24 mounted on the crank rocker arm mechanism 23, and a drill mechanism 25 mounted on the film breaking rod 24. A drive chain 26 is installed between the second drive wheel 21 and the first drive wheel 15.

[0022] In one example, the second transmission wheel 21 is rotatably mounted on the upper part of the vertical frame 113 via the drive shaft 22. The crank rocker arm mechanism 23 includes a first connecting rod 231 fixedly connected to the radial direction of the drive shaft 22, a second connecting rod 232 hinged to the lower part of the vertical frame 113, and a third connecting rod 233 hinged to the first connecting rod 231 and the second connecting rod 232 respectively. The vertical frame 113 between the first connecting rod 231 and the second connecting rod 232 serves as the fourth connecting rod. The first connecting rod 231 has the shortest length, so these four connecting rods can form the crank rocker arm mechanism 23. A mounting plate 234 is provided on the third connecting rod 233. The film breaking rod 24 is fixed to the mounting plate 234 by fasteners. The drill bit mechanism 25 is installed at the bottom of the film breaking rod 24. Power is transmitted to the drive shaft 22 via the first drive wheel 15, the second drive wheel 21, and the drive chain 26. The rotation of the drive shaft 22 drives the first connecting rod 231 to rotate, which in turn drives the third connecting rod 233 to swing up and down, ultimately driving the drill mechanism 25 to move in and out of the soil. It should be noted that the transmission ratio of the first drive wheel 15 and the second drive wheel 21 should be controlled so that the drill mechanism 25 drills a hole once after the traveling wheel 13 has moved a predetermined distance (transplanting spacing).

[0023] In one example, the drill bit mechanism 25 includes an upper plate 251, a lower plate 252, a drill bit shaft 253, a cutting disc 254, a soil rotating disc 255, a mudguard 256, a first spring 257, a first movable rod 258, a second gasoline engine 259, a flexible shaft 260, and a transmission mechanism 261. The upper plate 251 is fixedly installed at the bottom of the rupture rod 24. The lower plate 252 is connected to the lower part of the upper plate 251 by multiple fixed rods 265. The diameter of the lower plate 252 is smaller than that of the upper plate 251. The drill bit shaft 253 is rotatably installed on the lower plate 252. The cutting disc 254 and the soil rotating disc 255 are installed on the drill bit shaft 253 from bottom to top. There are two cutting discs 254, which are symmetrically installed on the drill bit. On shaft 253, the soil-rotating blade 255 is a spiral blade. The mudguard 256 is connected to the lower part of the upper plate 251 through multiple springs and the first movable rod 258. The bottom of the first movable rod 258 is fixed on the mudguard 256, and the top of the first movable rod 258 moves through the upper plate 251. The first spring 257 is sleeved on the first movable rod 258. The mudguard 256 surrounds the cutting plate 254 and the soil-rotating blade 255. The second gasoline engine 259 is mounted on the frame 11 and is connected to the transmission mechanism 261 through the flexible shaft 260. The transmission mechanism 261 is connected to the drill bit shaft 253. The transmission mechanism 261 is a conventional device for drilling equipment, such as a worm gear drive, which will not be described in detail here.

[0024] During operation, the second gasoline engine 259 transmits power to the drill bit shaft 253 via the flexible shaft 260 and transmission mechanism 261. As the crank-rocker arm mechanism 23 drives the drill bit shaft 253 downwards into the soil, the mudguard 256 first presses against the mulch film, then compresses the first spring 257. The drill bit shaft 253 continues downwards, the cutting blade cuts the mulch film, and drills holes in the soil. During the drilling process, the soil-rotating blade 255 rotates the soil upwards and throws it outwards. The thrown soil, blocked by the mudguard 256, falls onto the mulch film between the mudguard 256 and the soil-rotating blade 255, thus achieving the mulch film covering operation. Therefore, through the cooperation of the cutting blade 254, the soil-rotating blade 255, the mudguard 256, the first spring 257, and the first movable rod 258, this equipment can not only achieve drilling while covering the mulch film, but also rotate the soil generated during drilling and cover the mulch film around the drilled holes.

[0025] In one example, a second movable rod 262 is installed on both sides of the bottom of the vertical frame 113. The second movable rod 262 can move up and down relative to the vertical frame 113. A pressure roller 263 is provided at the bottom of the second movable rod 262. A second spring 264 is sleeved on the second movable rod 262. The pressure roller 263 can elastically press on the mulch film during movement, which can effectively improve the drilling effect when used in conjunction with fixing the mulch film.

[0026] The film covering unit includes a film cylinder frame 31, a film pressing wheel 32, and a soil guiding wheel 33, which are installed sequentially from front to back below the frame 11 and in front of the drill mechanism 25, with the film pressing wheel 32 and the soil guiding wheel 33 located on both sides of the frame 11.

[0027] In one example, the U-shaped frame 114 includes an upper horizontal bar 1141, a lower horizontal bar 1142, a vertical bar 1143, and a middle connecting rod 1144. The upper horizontal bar 1141 is located at the front end of the flat frame 111. The lower horizontal bar 1142 is connected to the lower part of the upper horizontal bar 1141 through the middle connecting rod 1144. The vertical bar 1143 is connected to both ends of the upper horizontal bar 1141 and the lower horizontal bar 1142. The traveling wheel 13 is installed on the side of the vertical bar 1143. The traveling wheel 13 can be a solid rubber wheel.

[0028] In one example, an adjusting rod 34 is connected to the top center of the membrane tube frame 31. The adjusting rod 34 is adjustable up and down and is mounted on a horizontal rod 35. The horizontal rod 35 is fixedly connected to the intermediate connecting rod 1144, so that the fixed position of the adjusting rod 34 can be changed as needed.

[0029] In one example, the adjusting rod 34 is equipped with a curved rod 36 extending downwards and to the rear. The lower end of the curved rod 36 is connected to a roller frame 37, on which a pressure roller 38 is mounted. Arc-shaped rods 39 are mounted on both sides of the roller frame 37. The pressure roller 38 is located below and behind the film cylinder frame 31. When the film cylinder frame 31 releases the mulch film, the pressure roller 38 can promptly press the mulch film on the ridge surface, while the arc-shaped rods 39 can also flatten the mulch film on both sides, improving the subsequent mulching and perforation effects.

[0030] In one example, the pressure roller 32 and the guide roller 33 are mounted on the longitudinal rod 41 via the bracket 40. The front end of the longitudinal rod 41 is adjustablely mounted on a longitudinal bent rod 42, and the front end of the longitudinal bent rod 42 is adjustablely mounted on the lower crossbar 1142, so that the lateral and longitudinal positions of the pressure roller 32 and the guide roller 33 can be adjusted as needed.

[0031] The working principle of the above-mentioned integrated machine for fixed-point film breaking and soil covering is as follows: The plastic film cylinder is installed on the film cylinder frame 31, and the vehicle frame 11 is placed on one side of the ridge. The traveling wheels 13 are located in the furrows on both sides. As the vehicle frame 11 is moved forward by the handle 112 and the first gasoline engine 12, the plastic film cylinder first releases the plastic film. Then, the pressing film and the arc rod 39 press the plastic film onto the ridge surface. The plastic film on both sides is pressed down by the pressing wheel 32, and the soil guide wheel 33 guides the soil in the furrows to the plastic film to cover and fix it. At the same time, under the power transmission of the first transmission wheel 15, the second transmission wheel 21, the transmission chain 26, and the drive shaft 22, the crank rocker arm mechanism 23 swings back and forth, driving the drill bit shaft 253 downward. When drilling into the soil, the mud-blocking cylinder 256 first presses down on the mulch film, then compresses the first spring 257, while the drill shaft 253 continues downward, the cutting blade cuts the mulch film and drills holes in the soil. During the drilling process, the rotating blade 255 rotates the soil upward and throws it out in all directions. The thrown soil falls onto the mulch film between the mud-blocking cylinder 256 and the rotating blade 255 under the obstruction of the mud-blocking cylinder 256, thus realizing the mulch film covering operation. Finally, the crank rocker arm mechanism 23 takes the drill shaft 253 out of the soil, and the mud-blocking cylinder 256 returns to its initial position under the action of gravity and the first spring 257, preparing for the next drilling.

[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
