[0040] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0041] like Figure 1-Figure 11 The tobacco planting furrowing and film covering integrated machine shown in the figure comprises a frame 1 and a power system, on which a rotatable secondary shaft 2 and a vibration frame 3 that can reciprocate along the axis direction of the secondary shaft 2 are installed, and a stroke adjustment component for adjusting the reciprocating stroke of the vibration frame 3 is provided on the frame 1;

[0042] The power system includes a power motor 13 installed on the side of the frame 1, a main shaft 14 and a vertical shaft 15 rotatably connected to the frame 1, the output shaft end of the power motor 13 is fixedly connected to the main shaft 14, and a first synchronous belt is transmission-connected between the main shaft 14 and the secondary shaft 2;

[0043] A first bevel gear is installed on the main shaft 14 and the vertical shaft 15, and the two first bevel gears are meshed with each other. A half-cone transmission column 16 is installed on the vertical shaft 15 for transmission. A reciprocating inclined plate 17 is installed on the vibration frame 3. The conical surface of the half-cone transmission column 16 contacts the inclined surface of the reciprocating inclined plate 17. A group of elastic reset members 18 are installed between the vibration frame 3 and the frame 1.

[0044] After the power motor 13 is started, it drives the main shaft 14 to rotate. The main shaft 14 drives the secondary shaft 2 to rotate through the first synchronous belt, providing power for the rotation of the hollow shaft 5 and the conical ditching disc 6 to achieve ditching operation. At the same time, the main shaft 14 drives the first bevel gear thereon to rotate, and the first bevel gear on the vertical shaft 15 meshing therewith rotates accordingly, thereby rotating the vertical shaft 15. The semi-conical transmission column 16 on the vertical shaft 15 cooperates with the reciprocating inclined plate 17 on the vibration frame 3. Under the action of the elastic reset member 18, the vibration frame 3 reciprocates along the axis direction of the secondary shaft 2;

[0045] The reciprocating movement of the vibration frame 3 along the axis direction of the secondary shaft 2 makes the soil in contact with the conical furrowing disc 6 fully vibrate and roll, thereby solving the problem that the soil is easy to harden and affect the growth of tobacco roots when the traditional furrowing equipment is furrowing. Compared with the prior art, the reciprocating vibration of the vibration frame 3 can loosen the soil, enhance the soil permeability, and is more conducive to tobacco growth, thereby improving tobacco yield and quality;

[0046] On the other hand, the reciprocating movement of the vibration frame 3 along the axis direction of the secondary shaft 2 can also realize the vibration shaking off of the soil adhering to the conical ditching disc 6, and the adhesion rate of the soil on the conical ditching disc 6 is effectively reduced by the vibration shaking off, thereby improving the ditching flatness of the conical ditching disc 6;

[0047] A comparative test was conducted at a tobacco planting base in Yunnan. Two test fields with similar soil conditions were selected. One field was planted with the integrated machine with the power system of the present invention, and the other field was planted with traditional ditching equipment. Under the same planting and management conditions, the tobacco planted with the equipment of the present invention had a more developed root system, an average plant height of 8 cm higher than that planted with traditional equipment, and 2-3 more leaves, ultimately achieving an increase in tobacco yield and better tobacco leaf quality.

[0048] The stroke adjustment assembly includes an adjustment screw rod 19 rotatably connected to the frame 1, the adjustment screw rod 19 is arranged parallel to the vertical axis 15, and a rotary handle is installed on the top of the adjustment screw rod 19;

[0049] A stroke adjustment slider 20 is installed on the adjusting screw rod 19, and the stroke adjustment slider 20 is slidably connected to the frame 1. The semi-conical transmission column 16 is rotatably installed on the stroke adjustment slider 20. An axis groove with two ends opened and slidably connected to the vertical shaft 15 is fixed inside the semi-conical transmission column 16. The cross-sections of the axis groove and the vertical shaft 15 are both regular hexagons. A group of elastic fastening members 21 are installed between the reciprocating inclined plate 17 and the vibration frame 3. Friction patterns are provided on the reciprocating inclined plate 17 and the semi-conical transmission column 16.

[0050] The elastic reset member 18 and the elastic pressing member 21 both include a T-shaped guide rod and a spring sleeved on the T-shaped guide rod;

[0051] By rotating the handle at the top of the adjusting screw 19, the stroke adjusting slider 20 can be moved up and down along the adjusting screw 19. Since the semi-conical transmission column 16 is installed on the stroke adjusting slider 20, and the semi-conical transmission column 16 is slidably connected with the vertical shaft 15 through the shaft groove, the cross-section of the shaft groove and the vertical shaft 15 is a regular hexagon, which ensures that the semi-conical transmission column 16 can move up and down with the stroke adjusting slider 20 while rotating with the vertical shaft 15. In this way, the relative position of the semi-conical transmission column 16 and the reciprocating inclined plate 17 can be changed, thereby adjusting the reciprocating stroke of the vibration frame 3;

[0052] This design solves the problem that the stroke of the vibration frame 3 cannot be flexibly adjusted when trenching under different soil conditions and planting requirements. Compared with the existing technology, the stroke of the vibration frame 3 can be flexibly adjusted according to actual conditions, thereby improving the applicability of the equipment;

[0053] For example, in a tobacco planting area in a mountainous area of ​​Guizhou, the soil is very sticky. When using this equipment, by adjusting the stroke adjustment component, the stroke of the vibration frame 3 is increased by 20%. The soil loosening effect after ditching is significantly improved, and the tobacco seed germination rate is increased by 15% compared with before adjustment, and the seedlings grow stronger.

[0054] In the subsequent growth process, the tobacco plants' resistance to lodging increased, reducing the losses caused by lodging due to windy weather;

[0055] Two adjustable-distance adjustment arms 4 are mounted on the vibration frame 3, and a hollow shaft 5 driven by the secondary shaft 2 is rotatably mounted on each adjustment arm 4, and two symmetrically arranged conical ditching discs 6 are mounted on the hollow shaft 5;

[0056] A first bidirectional screw rod 22 is rotatably mounted on the vibration frame 3, and a first positive thread portion and a first negative thread portion are respectively provided on the first bidirectional screw rod 22, and the first positive thread portion and the first negative thread portion are respectively connected to the two adjustment arms 4 in transmission, and a hollow groove with openings at both ends and slidably connected to the secondary shaft 2 is fixedly provided inside the hollow shaft 5, and the cross sections of the hollow groove and the secondary shaft 2 are both regular hexagons;

[0057] The first bidirectional screw rod 22 is rotated, and the first positive thread portion and the first reverse thread portion thereof drive the two adjustment arms 4 to move toward or away from each other along the vibration frame 3, thereby adjusting the distance between the two adjustment arms 4 to meet different planting row spacing requirements;

[0058] The secondary shaft 2 drives the hollow shaft 5 to rotate through the hollow groove, thereby causing the conical trenching disc 6 on the hollow shaft 5 to rotate to perform trenching operations;

[0059] This structure solves the problem that traditional furrowing equipment cannot flexibly adjust furrowing row spacing, improves the versatility of the equipment, and compared with the existing technology, can quickly adjust furrowing row spacing according to different tobacco varieties and planting plans, reducing the trouble and cost of replacing equipment parts;

[0060] In a tobacco planting area in Henan, two different varieties of tobacco are planted at the same time, one of which requires a wider row spacing, and the other is suitable for a narrower row spacing. By using the all-in-one machine of the present invention, the row spacing can be adjusted within 10 minutes by simply rotating the first bidirectional screw rod 22, thereby meeting the growth space requirements of different varieties of tobacco.

[0061] A rotatable film roll 7 is provided on the frame 1, and a liftable positioning platform 8 and a guide clamping assembly for clamping and guiding the film are respectively installed on the frame 1;

[0062] The guide clamp assembly includes a double-headed motor 23 installed on the side of the frame 1 and a clamping shaft 24 rotatably connected to the frame 1, one output shaft end of the double-headed motor 23 is fixedly connected to the clamping shaft 24, the film roll 7 is sleeved on the clamping shaft 24, and a limit ring that limits the position of the film roll 7 is threadedly installed on the clamping shaft 24. Two clamping rollers 25 are rotatably installed on the frame 1, and a linkage gear 26 is installed on each of the two clamping rollers 25. The two linkage gears 26 are meshed with each other, and the other output shaft end of the double-headed motor 23 is connected to a clamping roller 25 through a second synchronous belt. Both clamping rollers 25 are made of rubber;

[0063] After the double-headed motor 23 is started, the output shaft at one end drives the clamping shaft 24 to rotate, so that the film roll 7 is unwound. At the same time, the output shaft at the other end drives a clamping roller 25 to rotate through the second synchronous belt. Since the linkage gears 26 on the two clamping rollers 25 are meshed with each other, the two clamping rollers 25 rotate synchronously to clamp the film and guide it for transportation.

[0064] The limiting ring can prevent the film roll 7 from moving left and right on the clamping shaft 24, ensuring the stability of the film conveying. This design solves the problem of easy deviation and jamming of the film during conveying. Compared with the existing technology, it improves the stability and accuracy of the film conveying, reduces the waste of film and equipment failure;

[0065] An electrostatic roller 9 is rotatably mounted on the frame 1 and corresponds to the position between the positioning platform 8 and the guide clamp assembly. A high-voltage power supply 28 electrically connected to the electrostatic roller 9 is mounted on the side of the frame 1.

[0066] The high voltage power supply 28 supplies power to the electrostatic roller 9, so that the surface of the electrostatic roller 9 is charged with static electricity, and the coating is electrostatically adsorbed. When the winding motor is working, the electrostatic roller 9 is not powered and does not generate static electricity, so that the coating can be unwound normally.

[0067] When the winding motor is not working, the electrostatic roller 9 generates static electricity and adsorbs the coating film, so that the coating film can be effectively positioned in the shutdown state;

[0068] A set of lifting push rods 27 are installed between the frame 1 and the positioning platform 8. A cavity is fixedly opened inside the positioning platform 8. Two sets of air nozzles 10 connected with the cavity are installed on the bottom surface of the positioning platform 8. A pressure control module 11 is installed on the positioning platform 8. The pressure control module 11 is used to make the air nozzle 10 discharge air with positive pressure or inhale air with negative pressure.

[0069] An electric hot wire cutting 12 is installed on the positioning platform 8 and at a position corresponding to the rear side of the air nozzle 10;

[0070] The cross section of the electric heating wire 12 is circular, the radius of the electric heating wire 12 is 0.2 mm, and the heating temperature of the electric heating wire 12 is 200° C.;

[0071] When the integrated machine is about to turn, the lifting push rod 27 moves down, the positioning platform 8 approaches the film, the negative pressure pump works, and the air nozzle 10 generates negative pressure through the three-way hose to adsorb the film, and then the electric hot wire cutting 12 is energized to cut off the film;

[0072] When the turning is completed, the negative pressure pump stops working, the blower starts working, and the air nozzle 10 discharges air at positive pressure to press the cut-off covering film tightly onto the soil surface;

[0073] The electric heating wire 12 preferably has a radius of 0.2 mm and a heating temperature of 200° C., which can efficiently and stably cut off the coating instantly;

[0074] This design solves the problem that the film is difficult to cut and fix when the integrated machine turns. Compared with the existing technology, it realizes the automatic cutting and fixing of the film, and improves the automation and efficiency of the planting operation;

[0075] In the actual planting operation of a tobacco planting base in Hunan, after adopting this structure, the success rate of film cutting and fixing reached 98% after 100 turning operations. The film processing time for each turn was shortened from 3-5 minutes to 1-2 minutes, and the film fixing effect was better, reducing problems such as film warping, effectively improving planting efficiency and reducing labor intensity.

[0076] It also includes an electric control box 34 installed on the frame 1, and a battery and a single-chip microcomputer are installed inside the electric control box 34. A GPS locator 35, a three-axis acceleration sensor 36 and a remote central control module 37 are installed on the top surface of the electric control box 34. The data ends of the GPS locator 35, the three-axis acceleration sensor 36 and the remote central control module 37 are all connected to the single-chip microcomputer data. The single-chip microcomputer is powered by a battery. A follower frame 38 is hinged on the frame 1 and corresponds to the rear side of the electric hot wire cutting 12. A counterweight roller 39 is rotatably installed between the inner surfaces of the follower frame 38;

[0077] The data feedback from the GPS locator 35 and the three-axis acceleration sensor 36 is used to monitor the turning state and the straight-moving state of the integrated machine;

[0078] When the machine is in a straight-moving state, the winding motor works, the lifting push rod 27 is reset, and the negative pressure pump does not work;

[0079] When the machine is about to turn, the winding motor is turned off, the lifting push rod 27 moves down to a specified height, and the negative pressure pump generates negative pressure. After the negative pressure is generated, the multiple air nozzles 10 perform negative pressure adsorption on the film from above the film. After the negative pressure adsorption is completed, the electric hot wire cutter 12 is powered on and cuts off the film.

[0080] When the integrated machine has completed its turning, the winding motor restarts, the lifting push rod 27 is reset, the negative pressure pump generates positive pressure and blows air downward, so that the ventilation wind force presses the film tightly against the soil surface;

[0081] The GPS locator 35 obtains the location information of the integrated machine in real time, and the three-axis acceleration sensor 36 monitors the motion state of the integrated machine. These data are fed back to the single-chip microcomputer, which determines the turning and straight-moving state of the integrated machine based on the data and controls the operation of the corresponding components;

[0082] This design solves the problem that the integrated machine cannot automatically control lamination-related operations according to the driving status during operation. Compared with the existing technology, it improves the intelligence of the equipment, reduces manual intervention, and reduces labor intensity.

[0083] In a large tobacco planting area in Sichuan, the integrated machine with the electric control box 34 and related modules of the present invention is used for planting operations. During the entire planting season, the workload of manual operation is reduced by 40%, and the planting efficiency is increased by 30%. At the same time, because the equipment can automatically adjust the film covering operation according to the driving state, the laying quality of the film covering is more stable, creating good conditions for tobacco growth, and finally the yield and quality of tobacco are significantly improved;

[0084] The pressure control module 11 includes a chassis installed on the positioning platform 8, in which a negative pressure pump, a blower and a three-way hose are respectively installed. The negative pressure generating end of the negative pressure pump and the air outlet end of the blower are connected to the three-way hose. A solenoid valve is provided at the connection point between the three-way hose and the negative pressure pump and the blower, and the other end of the three-way hose is connected to the cavity.

[0085] By controlling the opening and closing of the solenoid valve in the chassis, the connection state of the negative pressure pump and the blower with the three-way hose can be switched. When the negative pressure pump is connected, the air nozzle 10 sucks air with negative pressure to absorb the film. When the blower is connected, the air nozzle 10 discharges air with positive pressure to press the film. This design solves the problem that a single pressure mode cannot meet the different film laminating operation requirements.

[0086] Compared with the prior art, the pressure mode of the air nozzle 10 can be flexibly switched according to the operation process, the operation is simple and convenient, and the quality and efficiency of the laminating operation are improved;

[0087] In a tobacco planting base in Fujian, when performing film coating operations, the pressure control module 11 is used, and the response time of switching the pressure mode is within 1-2 seconds. During a continuous 5-hour film coating operation, the pressure mode is switched smoothly, and the film coating adsorption and pressing effects are good, which greatly improves the continuity of the operation. The overall film coating operation efficiency is increased by 25% compared with the use of a single pressure mode device;

[0088] A film pressing assembly is installed on the frame 1 at a position corresponding to the rear side of the positioning platform 8 .

[0089] The film pressing assembly includes a second bidirectional screw rod 29 rotatably connected to the frame 1, a driving nut is installed on the first bidirectional screw rod 22 and the second bidirectional screw rod 29, a second bidirectional screw rod 29 is respectively provided with a second positive thread portion and a second reverse thread portion, the second positive thread portion and the second reverse thread portion are both transmission-connected with an upper support seat 30, the upper support seat 30 is slidably connected to the frame 1 through a guide rail, a lower support seat 31 is slidably installed below the upper support seat 30, a film pressing wheel 32 is rotatably installed on the lower support seat 31, the film pressing wheel 32 is made of silicone, a positioning screw rod 33 is rotatably installed on the top surface of the lower support seat 31, and the positioning screw rod 33 is threadedly connected to the frame 1.

[0090] The second bidirectional screw 29 is rotated, and the second positive thread portion and the second negative thread portion on the screw drive the two upper support seats 30 to move toward or away from each other along the guide rail, thereby adjusting the distance between the two film pressing wheels 32 to adapt to films of different widths;

[0091] The lower support seat 31 can slide up and down along the upper support seat 30. The height of the lower support seat 31 can be adjusted by rotating the adjustment screw rod 33, thereby adjusting the degree of compression of the film pressing wheel 32 on the film. The film pressing wheel 32 is made of silicone material, which can ensure sufficient pressure on the film without damaging the film. This design solves the problem that the traditional film pressing device cannot flexibly adjust the spacing and compression of the film pressing wheel 32;

[0092] Compared with the existing technology, the effect and adaptability of film pressing are improved, ensuring that the film fits tightly with the soil, which is conducive to maintaining soil moisture and temperature;

[0093] In a tobacco planting test field in Guangxi, planting tests were conducted using films of different widths, and good film pressing effects were achieved by using the film pressing assembly of the present invention.

[0094] When using a wider covering film, the covering film is closely attached to the soil by adjusting the spacing and the degree of compression of the film pressing wheels 32, so that the soil moisture remains stable within a week and the tobacco seedlings grow well.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
