Description

Technical Field

[0001] The invention relates to a fixed-point film-breaking and soil-covering integrated machine for film covering, and belongs to the technical field of film covering and transplanting of tobacco field ridges. Background Art

[0002] At present, before transplanting flue-cured tobacco, it is often necessary to perform land preparation and ridge-forming, mulch film covering, and drilling and covering with soil in sequence. Among them, land preparation and ridge-forming for flue-cured tobacco refers to leveling and refining the tobacco planting area through appropriate land treatment methods, and forming a standardized management model for ridge-forming. Its purpose is to improve planting efficiency, reduce the occurrence of diseases and pests, promote crop growth, improve tobacco leaf quality, and increase farmers' income. Mulch film covering refers to a crop yield-increasing cultivation measure that uses agricultural plastic film to cover the ground surface to retain heat, retain moisture, conserve soil, increase production, and reduce weeds. Drilling and covering with soil refers to breaking the film mouth at a fixed point on the tobacco ridge covered with film according to the transplanting plant spacing, covering the broken film mouth with soil and compacting the film mouth to make it into a butterfly shape. Drilling and covering with soil for transplanting can alleviate the evaporation of water from the film mouth, prevent the excessive growth of weeds, reduce the damage of slugs, and achieve early growth and rapid development of tobacco plants. At present, The current film covering machine mechanically covers the film covering material on the surface of the farmland to form a protective film. It usually consists of a film covering machine and a mobile platform. The film covering machine is responsible for spreading the film covering material, while the mobile platform moves the film covering machine to the place where it needs to be covered. The film covering machine starts the film covering operation, and the covering mouth continues to unearth to compact the ground film. Finally, the ground film is cut by the film cutting knife to complete the one-time operation of ridge forming and film covering. This mechanized operation method greatly improves the efficiency and quality of film covering. However, the current film covering machine can only realize film covering, but cannot realize the punching function, and is not suitable for tobacco integrated operation. Summary of the invention

[0008] In one example, the drill mechanism includes an upper disc body, a lower disc body, a drill shaft, a film cutting piece, a soil rotating piece, a mud guard tube, a first spring, a first movable rod, a second gasoline engine, a flexible shaft and a transmission mechanism, the upper disc body is fixed to the bottom of the film breaking rod, the lower disc body is connected to the bottom of the upper disc body through a fixed rod, the drill shaft can be rotatably installed on the lower disc body, the drill shaft is sequentially installed with a film cutting piece and a soil rotating piece from bottom to top, the soil rotating piece is a spiral piece, the mud guard tube is connected to the bottom of the upper disc body through multiple springs and a first movable rod, the bottom of the first movable rod is fixed on the mud guard tube, the top of the first movable rod can move through the upper disc body, and the first spring is sleeved on the first movable rod, the mud guard tube surrounds the film cutting piece and the soil rotating piece, the second gasoline engine is installed on the frame, it is connected to the transmission mechanism through a flexible shaft, and the transmission mechanism is connected to the drill shaft.

[0009] In one example, second movable rods are installed on both sides of the bottom of the vertical frame, a film pressing roller is provided at the bottom of the second movable rod, and a second spring is sleeved on the second movable rod.

[0010] In one example, the U-shaped frame includes an upper cross bar, a lower cross bar, a vertical bar and an intermediate connecting rod, the upper cross bar is located at the front end of the flat frame, the lower cross bar is connected to the bottom of the upper cross bar through the intermediate connecting rod, the vertical bar is connected to both ends of the upper cross bar and the lower cross bar, and the walking wheels are installed on the side of the vertical bar.

[0011] In one example, an adjusting rod is connected to the middle top of the film cylinder frame. The adjusting rod can be adjusted up and down and is installed on a transverse rod. The transverse rod is fixedly connected to the middle connecting rod.

At the same time, under the power transmission of the first transmission wheel, the second transmission wheel, and the transmission chain, the crank rocker mechanism swings back and forth, and the drilling and covering of the soil is realized synchronously when the drill shaft is driven to drill downward into the soil. In addition, the mud guard cylinder is first pressed on the film when drilling, and then the first spring is compressed, while the drill shaft continues to move downward, the film cutting knife cuts the film, and drills holes in the soil. During the drilling process, the soil rotating blade rotates the soil upward and throws it out to all sides. Under the blocking action of the mud guard cylinder, the thrown soil falls on the film between the mud guard cylinder and the soil rotating blade, thereby realizing the film covering operation and avoiding soil splashing, and forming a regular disc-shaped transplanting port on the film.

[0015] This equipment seamlessly integrates the two links of film covering and fixed-point soil covering, moves the soil filling and sealing operation process forward, effectively alleviating the problem of labor difficulty in this link, and at the same time provides convenience for subsequent transplanting operations, making transplanting more efficient and accurate. It improves the mechanized operation level of tobacco fields and improves operating efficiency, reduces production labor, reduces labor costs, and lays the foundation for achieving full mechanization.

[0018] See also Figures 1 to 7 , this embodiment is a film covering fixed-point film breaking and soil covering integrated machine, including 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 , wherein the transmission component 14 has a first transmission wheel 15 .

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

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

[0022] In one example, the second transmission wheel 21 is rotatably mounted on the upper part of the vertical frame 113 through the driving shaft 22, and the crank rocker mechanism 23 includes a first connecting rod 231 fixedly connected to the driving shaft 22 in the radial direction, 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 length of the first connecting rod 231 is the shortest, so that these four connecting rods can form the crank rocker mechanism 23, and 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, and the drill mechanism 25 is installed at the bottom of the film-breaking rod 24. The power is transmitted to the driving shaft 22 through the first transmission wheel 15, the second transmission wheel 21 and the transmission chain 26. The driving shaft 22 rotates to drive the first connecting rod 231 to rotate, and then drives the third connecting rod 233 to swing up and down, and finally drives the drill mechanism 25 to enter and exit the soil. It should be noted that the transmission ratio of the first transmission wheel 15 and the second transmission wheel 21 should be controlled so that the drill mechanism 25 drills a hole once after the walking wheel 13 moves a predetermined distance (transplanting spacing).

[0023] In one example, the drill mechanism 25 includes an upper disk body 251, a lower disk body 252, a drill shaft 253, a film cutting piece 254, a soil rotating piece 255, a mud retaining cylinder 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 disk body 251 is fixedly installed at the bottom of the film breaking rod 24, and the lower disk body 252 is connected to the lower part of the upper disk body 251 through a plurality of fixed rods 265. The diameter of the lower disk body 252 is smaller than that of the upper disk body 251. The drill shaft 253 is rotatably installed on the lower disk body 252. The film cutting piece 254 and the soil rotating piece 255 are sequentially installed on the drill shaft 253 from bottom to top. The film cutting piece 254 is two pieces, which are symmetrically installed on the drill head. On the shaft 253, the soil rotating piece 255 is a spiral piece, the mud guard tube 256 is connected to the bottom of the upper disk body 251 through multiple springs and the first movable rod 258, the bottom of the first movable rod 258 is fixed on the mud guard tube 256, the top of the first movable rod 258 moves through the upper disk body 251, and the first spring 257 is sleeved on the first movable rod 258, the mud guard tube 256 surrounds the film cutting piece 254 and the soil rotating piece 255 therein, the second gasoline engine 259 is installed on the frame 11, and it is connected to the transmission mechanism 261 through the flexible shaft 260, the transmission mechanism 261 is connected to the drill shaft 253, the transmission mechanism 261 is a conventional equipment of the drilling equipment, such as a worm gear transmission, which will not be repeated here.

[0024] When working, the second gasoline engine 259 transmits power to the drill shaft 253 through the flexible shaft 260 and the transmission mechanism 261. When the crank rocker mechanism 23 drives the drill shaft 253 to drill downward into the soil, the mud guard 256 first presses on the ground film, and then compresses the first spring 257, while the drill shaft 253 continues to move downward, the film cutter cuts the ground film, and drills holes in the soil. During the drilling process, the soil rotating piece 255 rotates the soil upward and throws it out to the surroundings. The thrown soil falls on the ground film between the mud guard 256 and the soil rotating piece 255 under the blocking effect of the mud guard 256, thereby realizing the film covering operation. Therefore, the device can not only realize drilling while covering the film through the cooperation of the film cutting piece 254, the soil rotating piece 255, the mud guard 256, the first spring 257 and the first movable rod 258, but also can rotate the soil produced by the drilling and cover it on the film around the hole.

[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 film pressing roller 263 is provided at the bottom of the second movable rod 262, and a second spring 264 is sleeved on the second movable rod 262. The film pressing roller 263 can be elastically pressed on the ground film during movement, and can effectively improve the punching effect by cooperating with the fixed ground film.

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

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

[0028] In one example, an adjusting rod 34 is connected to the middle top of the film cylinder frame 31. The adjusting rod 34 can be adjusted up and down and is installed on a transverse rod 35. The transverse rod 35 is fixedly connected to the middle connecting rod 1144, so that the fixed position of the adjusting rod 34 can be changed as needed.

[0029] In one example, the adjustment rod 34 is equipped with a curved rod 36 extending downwardly and rearwardly, and the lower end of the curved rod 36 is connected to a roller frame 37, on which a film pressing roller 38 is installed, and arc rods 39 are installed on both sides of the roller frame 37. The film pressing roller 38 is located at the rear and lower part of the film drum frame 31. When the film drum frame 31 releases the ground film, the film pressing roller 38 can timely press the ground film on the upper part of the ridge body onto the ridge surface, and the arc rod 39 can also flatten the ground film on both sides, thereby improving the subsequent film covering and punching effects.

[0030] In one example, the film pressing wheel 32 and the soil guide wheel 33 are installed on the longitudinal rod 41 through the bracket 40, and the front end of the longitudinal rod 41 can be adjustably installed on a longitudinal curved rod 42, and the front end of the longitudinal curved rod 42 can be adjustably installed on the lower cross bar 1142, so that the two sides and longitudinal position of the film pressing wheel 32 and the soil guide wheel 33 can be adjusted as needed.

[0031] The working principle of the above-mentioned film covering fixed-point film breaking and soil covering integrated machine is as follows: The ground film cylinder installation device is placed on the film cylinder frame 31, and the frame 11 is placed on one side of the ridge body. The walking wheels 13 are located in the furrows on both sides. During the process of driving the frame 11 forward by the handrail 112 and the first gasoline engine 12, the ground film cylinder first releases the ground film, and then the film pressing and arc rod 39 press the ground film on the ridge surface, and the ground film on both sides is pressed by the film pressing wheel 32, and the soil in the furrow is guided to the ground film by the soil guide wheel 33 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 driving shaft 22, the crank rocker mechanism 23 swings back and forth, driving the drill shaft 253 downward When drilling into the soil, the mud guard cylinder 256 first presses on the ground film, and then compresses the first spring 257, while the drill bit shaft 253 continues to move downward, the film cutting knife cuts the ground film, and drills a hole in the soil. During the drilling process, the soil rotating piece 255 rotates the soil upward and throws it around. The thrown soil falls on the ground film between the mud guard cylinder 256 and the soil rotating piece 255 under the blocking effect of the mud guard cylinder 256, thereby realizing the film covering operation. Finally, the crank rocker arm mechanism 23 brings the drill bit shaft 253 out of the soil, and the mud guard cylinder 256 returns to its initial position under the action of gravity and the first spring 257, preparing for the next hole drilling.

[0032] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
