Description

Technical Field

[0001] This utility model relates to the field of corn planting and harvesting technology, and in particular to an integrated corn planting and mulching machine. Background Technology

[0002] As a vital food crop worldwide, maize is characterized by its drought resistance, cold tolerance, tolerance to poor soil conditions, and strong environmental adaptability, holding a significant position in my country's agricultural production. With the development of modern agriculture towards higher efficiency and intelligence, higher demands are being placed on the multi-functional integration and operational efficiency of maize planting equipment.

[0003] According to the patent "An Integrated Corn Planting and Mulching Machine" published in CN220799051U, although it integrates the functions of planting and mulching and solves the problem of dust pollution through a dust collection component, it still has significant shortcomings in practical applications.

[0004] When the film-covering wheel of the film-covering mechanism in this patent needs to be replaced, the operation process is cumbersome and time-consuming, making it difficult to replace quickly, which affects the film-covering efficiency and meets the needs of high-efficiency operation. At the same time, the equipment lacks irrigation and fertilization functions, and cannot complete the application of water and fertilizer simultaneously after sowing, resulting in a disconnect in agronomic links. Additional equipment or manual work is required to make up for the work, which increases costs and reduces efficiency.

[0005] Therefore, we propose an integrated corn planting and mulching machine. Utility Model Content

[0006] The purpose of this utility model is to solve the shortcomings of the existing technology. When the film covering wheel of the film covering mechanism in the patent needs to be replaced, the operation process is cumbersome and time-consuming, making it difficult to replace quickly, which affects the film covering efficiency and meets the needs of high-efficiency operation. At the same time, the equipment lacks irrigation and fertilization functions and cannot complete the application of water and fertilizer simultaneously after sowing, resulting in a disconnect in agronomic links. Additional equipment or manual work is required, which increases costs and reduces efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A corn planting and mulching integrated machine, comprising:

[0009] The vehicle body is equipped with casters at its four corners;

[0010] A seeding assembly, located on the right side of the top of the vehicle body, is used for seeding corn.

[0011] The irrigation and fertilization mechanism is located at the center of the top of the vehicle body. It includes a storage box, a drive and stirring unit and a spraying unit. The drive and stirring unit is used to stir the mixed solution inside the storage box and spray it onto the soil after sowing through the spraying unit.

[0012] A film covering mechanism is located on the left side of the irrigation and fertilization mechanism. It includes a drive rotating part and a winding part. The drive rotating part and the winding part are connected and disassembled by four bolts. The drive rotating part is used to drive the winding part to rotate.

[0013] A tension control mechanism is located on the left side of the coating mechanism and is used to apply pressure to the film during the coating process.

[0014] As a preferred embodiment of this utility model, the driving stirring unit includes:

[0015] A rotating rod is installed inside the storage box;

[0016] Several stirring rods are fixedly installed at equal intervals on the rotating rod.

[0017] The first drive motor is mounted on the back side wall of the storage box and is used to drive the rotating rod to rotate.

[0018] As a preferred embodiment of this utility model, the spraying unit includes:

[0019] A connecting component is located on the right side of the storage box.

[0020] The pump body is disposed on the back side wall of the connecting member, and its output end is connected to the connecting member;

[0021] A connecting pipe is provided on the connecting piece, and one end of the pipe passes through the side wall of the storage box and is connected to the interior of the storage box.

[0022] The spray nozzle is located at the bottom of the vehicle body, and its left side is connected to the connecting pipe;

[0023] Two fixing blocks are installed on the front and back side walls of the sprayer base respectively, to fix the sprayer base to the bottom of the vehicle body;

[0024] There are several spray nozzles, which are fixedly installed at the bottom of the spray base and are all connected to the spray base;

[0025] There are two feed inlets, located on the top of the storage box.

[0026] As a preferred embodiment of this utility model, the driving rotating part includes:

[0027] The mounting bracket is fixedly installed on the top of the vehicle body;

[0028] The speed reducer is fixedly mounted on the back side wall of the mounting base, and its output end is also provided with an output shaft that passes through the mounting base;

[0029] The second drive motor is mounted on the reducer;

[0030] A rotating disc is fixedly mounted on the output shaft of the reducer;

[0031] The limit support shaft is fixedly installed at the center of the front of the rotating disk.

[0032] As a preferred embodiment of this utility model, the winding component includes:

[0033] The fixed plate is secured to the rotating plate by four bolts.

[0034] The winding post is fixedly connected to the fixed plate and is used to hold the winding film.

[0035] As a preferred embodiment of this utility model, the tension control mechanism includes:

[0040] Compared with the prior art, the beneficial effects of this utility model are:

[0041] In this utility model, by integrating the sowing component, irrigation and fertilization mechanism, mulching mechanism and tension control mechanism into the vehicle body, the entire process of corn planting from sowing to mulching is integrated. The winding component and the drive rotating part adopt a bolt connection structure, which gets rid of the cumbersome process of disassembling bolts with tools in traditional patents. Operators can directly complete the disassembly and assembly of the winding component, which greatly shortens the replacement time of a single roll of film, effectively improves the continuous operation capability of the equipment, and solves the problem of low replacement efficiency in the prior art.

[0042] The tension control mechanism applies dynamic pressure to the film by driving the pressure pile through an electric push rod. It can adjust the tension in real time according to the film covering speed and changes in film roll diameter, avoiding wrinkles and tears caused by uneven tension during the film covering process. Compared with the structure without tension control in the background technology, it significantly improves the flatness and stability of the film covering and ensures the heat preservation and moisture retention effects.

[0043] The irrigation and fertilization mechanism stirs the mixed solution in the storage tank by driving the stirring unit, and then evenly sprays it onto the soil after sowing through the spraying unit, realizing the simultaneous operation of sowing and water and fertilizer application. This structure can provide water and nutrients for seed germination in a timely manner, reduce the cost of subsequent manual application, and avoid the soil compaction problem caused by segmented operation, thereby improving the corn emergence rate and growth quality.

[0054] Example

[0055] like Figure 1-5 As shown, this utility model provides a technical solution: a corn planting and mulching integrated machine, comprising:

[0056] The vehicle body 10 has wheels at its four corners;

[0057] The seeding component 30 is located on the right side of the top of the vehicle body 10 and is used for seeding corn.

[0058] The irrigation and fertilization mechanism 20 is located at the center of the top of the vehicle body 10. It includes a storage box 201, a driving and stirring part and a spraying part. The driving and stirring part is used to stir the mixed solution inside the storage box 201 and spray it onto the soil after sowing through the spraying part.

[0059] The film covering mechanism 40 is located on the left side of the irrigation and fertilization mechanism 20. It includes a drive rotating part and a winding part. The drive rotating part and the winding part are connected and disassembled by four bolts. The drive rotating part is used to drive the winding part to rotate.

[0060] Tension control mechanism 50 is located on the left side of coating mechanism 40 and is used to apply pressure to the film during coating by coating mechanism 40.

[0061] The vehicle body 10 moves in the field via its four corner wheels. As the sowing assembly 30 moves with the vehicle body, it sows corn seeds into the soil. After sowing, the driving stirring part of the irrigation and fertilization mechanism 20 stirs the water-fertilizer mixture in the storage box 201 to prevent sedimentation, and then sprays the solution onto the sowing area through the spraying part. Subsequently, the driving rotating part of the mulching mechanism 40 drives the winding member to rotate, unfolding the mulch film wound on the winding member and laying it on the soil surface. At the same time, the tension control mechanism 50 applies pressure to the unfolded mulch film to ensure that the mulch film is laid flat and avoids wrinkles or looseness.

[0062] The driving stirring unit includes:

[0063] The rotating rod 202 is installed inside the storage box 201;

[0064] Several stirring rods 203 are fixedly installed at equal intervals on the rotating rod 202;

[0065] The first drive motor 204 is installed on the back side wall of the storage box 201 and is used to drive the rotating rod 202 to rotate.

[0066] After the first drive motor 204 starts, it outputs power to drive the rotating rod 202 to rotate inside the storage box 201. The stirring rods 203, which are evenly distributed on the rotating rod 202, rotate synchronously with the rotating rod 202, and stir the water-fertilizer mixture solution inside the storage box 201 in all directions. The mechanical movement of the stirring rods makes the fertilizer particles in the solution fully mixed with water, avoids sedimentation, and ensures that the solution concentration is uniform when spraying.

[0067] The spraying unit includes:

[0068] The connecting component 206 is located on the right side of the storage box 201;

[0069] Pump body 207 is disposed on the back side wall of connecting member 206, and its output end is connected to connecting member 206;

[0070] The connecting pipe 208 is installed on the connecting piece 206, and one end of it passes through the side wall of the storage box 201 and is connected to the interior of the storage box 201.

[0071] The spraying seat 209 is located at the bottom of the vehicle body 10, and its left side is connected to the connecting pipe 208;

[0072] Two fixing blocks 210 are installed on the front and back side walls of the sprayer 209 respectively, and are used to fix the sprayer 209 to the bottom of the vehicle body 10.

[0073] There are several spray nozzles 211, which are fixedly installed at the bottom of the spray base 209 and are all connected to the spray base 209.

[0074] There are two feed inlets 205, located on top of the storage box 201.

[0075] The water-fertilizer mixture is injected into the storage tank 201 through the inlet 205. After the pump body 207 is started, it generates suction, which draws the solution in the storage tank 201 into the connecting member 206 through the connecting pipe 208. After being pressurized by the pump body 207, it is delivered to the connecting pipe 208. The solution flows along the connecting pipe 208 into the spraying seat 209 at the bottom of the vehicle body 10, and is evenly sprayed onto the soil surface after sowing through several spraying nozzles 211 at the bottom of the spraying seat 209. The fixing block 210 ensures that the spraying seat 209 is stably installed and avoids shaking during spraying.

[0076] The drive rotating part includes:

[0077] Mounting bracket 401 is fixedly installed on the top of vehicle body 10;

[0078] The reducer 402 is fixedly mounted on the back side wall of the mounting base 401, and its output end is also provided with an output shaft that passes through the mounting base 401.

[0079] The second drive motor 403 is mounted on the reducer 402;

[0080] The rotating disk 404 is fixedly mounted on the output shaft of the reducer 402;

[0081] The limiting support shaft 405 is fixedly installed at the center of the front of the rotating disk 404.

[0082] After the second drive motor 403 starts, it outputs high-speed power. After being reduced and increased in torque by the reducer 402, it is transmitted to the rotating disk 404 through the output shaft, driving the rotating disk 404 to rotate at a suitable speed. The limiting support shaft 405 at the center of the front of the rotating disk 404 rotates synchronously with the rotating disk 404. The limiting support shaft 405 is used to support the winding component, ensuring that the winding component maintains the stability of the axis during rotation and avoids deviation. The reduction effect of the reducer 402 makes the film covering speed match the vehicle body moving speed, ensuring that the film is laid evenly.

[0083] The reel includes:

[0084] The fixed plate 406 is fixedly mounted on the rotating plate 404 by four bolts;

[0085] The winding post 407 is fixedly connected to the fixed plate 406 and is used to hold the winding film.

[0086] The fixed plate 406 is fixedly connected to the rotating plate 404 by four bolts to ensure that the two rotate synchronously. The winding film is sleeved on the winding pile 407. When the rotating plate 404 driving the rotating part drives the fixed plate 406 to rotate, the winding pile 407 rotates accordingly, so that the winding film gradually unfolds and is laid on the soil surface. The bolt connection method makes it easy to disassemble the fixed plate 406 to replace the new winding film and improve work efficiency.

[0087] Tension control mechanism 50 includes:

[0088] Two electric push rods 501 are fixedly installed on the top of the vehicle body 10;

[0089] Two mounting brackets 502 are located at the bottom of the vehicle body 10 and are fixed to the output ends of the two electric push rods 501.

[0090] Both bearings 503 are mounted on the mounting bracket 502;

[0091] The pressure pile 504 is set between the two bearings 503 and is used to apply pressure to the membrane.

[0092] The electric push rod 501 adjusts the height of the mounting frame 502 through telescopic movement, thereby controlling the pressure between the pressure pile 504 and the mulch film. The two ends of the pressure pile 504 are mounted on the mounting frame 502 through bearings 503 and can rotate freely. When the mulch film passes under the pressure pile 504, the electric push rod 501 pushes the pressure pile 504 down to make the mulch film receive uniform pressure. At the same time, the pressure pile 504 rotates with the mulch film under the support of the bearings 503, avoiding friction damage to the mulch film, thereby maintaining stable tension during mulch film laying and ensuring that the mulch film is tightly attached to the soil surface.

[0093] Workflow

[0094] 1. Vehicle movement and seeding stage

[0095] The vehicle body 10 moves through the field via the four corner wheels, which in turn move the seeding component 30 on the top right side in sync. The seeding component 30 sows the corn seeds during the movement and plants them into the soil at a set interval, laying the foundation for subsequent growth.

[0096] 2. Irrigation and fertilization system operation phase

[0097] After sowing is completed, the irrigation and fertilization system will be activated.

[0098] Solution stirring: The water-fertilizer mixture solution is injected through the feed inlet 205 at the top of the storage tank 201. The first drive motor 204 drives the rotating rod 202 to rotate, which in turn drives the stirring rod 203 to stir the solution, prevent fertilizer from settling and ensure uniform concentration.

[0099] Solution spraying: After the pump body 207 is started, the solution is drawn from the storage tank 201 through the connecting pipe 208, pressurized through the connecting piece 206 and delivered to the spray seat 209 at the bottom of the vehicle body 10. Then, it is evenly sprayed onto the soil surface of the sowing area through the spray nozzle 211 at the bottom of the spray seat 209 to complete irrigation and fertilization.

[0100] 3. The mulching mechanism unfolds the mulch film.

[0101] After irrigation and fertilization, the mulching mechanism 40 begins operation:

[0102] Drive rotation: The second drive motor 403 reduces speed and increases torque through the reducer 402, driving the rotating disk 404 to rotate, and the limit support shaft 405 on the rotating disk 404 rotates synchronously.

[0103] Mulch film laying: The mulch film wound on the winding pile 407 is unwound as the fixed plate 406 is fixed to the rotating plate 404 by bolts. The mulch film is gradually released from the winding pile 407 and laid on the soil surface after sowing and fertilization to form a covering layer.

[0104] 4. Tension control mechanism for leveling the mulch film stage

[0105] During the mulching process, the tension control mechanism 50 simultaneously applies pressure to the mulch film:

[0106] Pressure adjustment: The electric push rod 501 adjusts the height of the mounting frame 502 through telescopic movement, so that the pressure pile 504 is pressed down to the appropriate position.

[0107] Tension maintenance: When the mulch passes under the pressure pile 504, the pressure pile 504 rotates with the mulch under the support of the bearing 503, and at the same time applies uniform pressure to the mulch, eliminating wrinkles and ensuring that the mulch adheres tightly to the soil, avoiding mulch loosening due to insufficient tension or damage due to excessive tension.

[0108] 5. Cyclic operation and parts replacement

[0109] When a roll of plastic film is used up, the bolts between the fixed plate 406 and the rotating plate 404 can be removed to replace the new winding post 407 and the plastic film roll, and the operation can continue.

[0110] The water-fertilizer solution in the storage box 201 can be replenished through the feed inlet 205 to ensure the continuity of the irrigation and fertilization process.

[0111] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
