Description

Technical Field

[0001] This application relates to the field of agricultural machinery and equipment, and in particular to an electrically controlled ridging and mulching machine. Background Technology

[0002] With the scaling up and modernization of agricultural production, mulching film technology has been widely used in crop cultivation to improve the crop growing environment.

[0003] Chinese patent application CN117016078A discloses a ridging and mulching machine, including a frame that moves under the traction of a tractor. From front to back, the frame is equipped with a rotary tillage mechanism, a ridging mechanism, a mulching mechanism, and a soil covering mechanism. The rotary tillage mechanism is used to till the land; the ridging mechanism is used to rid the tilled land; the mulching mechanism is used to cover the ridges with mulch; and there are two soil covering mechanisms, installed on both sides of the frame, to cover the sides of the mulched area with soil. This mulching machine can complete operations such as breaking the soil, rotary tillage, stubble removal, deep loosening, ridging, mulching, and covering the mulch with soil, maximizing soil aeration and moisture retention.

[0004] However, during the mulching process, there are issues with the mulch film being either loose or too tight, which affects the quality of the mulching operation. Summary of the Invention

[0005] To facilitate the adjustment of mulching tension and improve mulching quality, this application provides an electrically controlled ridging and mulching machine.

[0006] This application provides an electrically controlled ridging and mulching machine, which adopts the following technical solution:

[0007] An electrically controlled ridging and mulching machine includes a vehicle body, a frame, a mulching mechanism, and a soil covering mechanism. The frame is mounted on the vehicle body, and the mulching mechanism includes a mulching roller and a pressing roller, which are rotatably mounted on the frame.

[0008] The frame is equipped with a tension roller for contacting the lower surface of the mulch film, and the frame is also equipped with an adjustment component for adjusting the position of the tension roller to adjust the tension of the mulch film.

[0009] By adopting the above technical solution, during the operation, the vehicle moves along the field to be covered with mulch, the mulch film on the mulching roller is gradually unrolled, the pressing roller presses the mulch film firmly onto the soil, and the soil covering mechanism covers the mulch film with soil, completing the mulching operation. During this process, the tension roller comes into contact with the mulch film, serving to tighten it. Furthermore, the adjusting component can adjust the position of the tension roller, thereby adjusting the tension force to prevent the mulch film from becoming overly tensile or slack due to changes in vehicle speed or other factors, thus improving the mulching quality.

[0010] Optionally, the adjustment assembly includes an adjustment cylinder, which is fixedly mounted on the frame. A mounting frame is fixedly mounted on the piston rod of the adjustment cylinder, and the tension roller is mounted on the mounting frame.

[0011] Optionally, the system also includes a membrane tension sensor and a controller. The membrane tension sensor is used to detect the tension of the mulch film and output a detection signal. The controller responds to the detection signal and controls the movement of the adjusting cylinder. If the detection signal is lower than a preset value, the controller controls the adjusting cylinder to extend to increase the tension of the mulch film. If the detection signal is higher than the preset value, the controller controls the adjusting cylinder to shorten to reduce the tension of the mulch film.

[0012] By adopting the above technical solution, the tension sensor can detect the tension of the mulch film in real time. If the detected signal is lower than the preset value, i.e., the mulch film is too loose, the controller controls the adjusting cylinder to extend to increase the tension of the mulch film; if the detected signal is higher than the preset value, i.e., the mulch film is too tight, the controller controls the adjusting cylinder to shorten to reduce the tension of the mulch film. This ensures that the mulch film is evenly and uniformly covered on the land during the mulching process, improving the mulching quality.

[0013] Optionally, the frame is provided with a limiting component for contacting the mulch film on the covering roller.

[0014] Optionally, the limiting component includes a pressure roller and a driving member. The pressure roller is rotatably mounted on the frame, and the driving member is used to drive the pressure roller to press against the film on the film-coating roller.

[0015] Optionally, the frame includes a fixed frame and a movable frame. The fixed frame is fixedly mounted on the vehicle body, and the movable frame is hinged to the end of the fixed frame away from the vehicle body. A deflecting element is provided between the fixed frame and the movable frame for driving the movable frame to deflect around the fixed frame.

[0016] Optionally, the soil covering mechanism includes a soil covering cutter head, and the movable frame is provided with an installation rod, with the soil covering cutter head rotatably mounted at the bottom end of the installation rod.

[0017] Optionally, a sleeve is fixedly installed on the movable frame, and the mounting rod slides through the sleeve in a vertical direction. An elastic element for driving the mounting rod to move downward is provided between the mounting rod and the sleeve.

[0018] Optionally, a pull rope is fixedly connected to the mounting rod, and a drive assembly for driving the pull rope to move upward is provided on the movable frame.

[0019] Optionally, the drive assembly includes a drive motor and a winding wheel. The drive motor is fixedly mounted on the movable frame, the winding wheel is rotatably mounted on the movable frame, and the output shaft of the drive motor is fixedly connected to the winding wheel. The pull rope is wound around the winding wheel.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. During operation, the vehicle moves along the field requiring mulching. The mulch film on the mulching rollers is gradually unrolled, and the pressing rollers press the film firmly onto the soil. The soil covering mechanism then covers the film with soil, completing the mulching operation. During this process, the tension rollers contact the mulch film, providing tension. The adjusting components can adjust the position of the tension rollers, thereby adjusting the tension force to prevent over-tensioning or slackness of the film due to changes in vehicle speed or other factors, thus improving the mulching quality.

[0022] 2. The tension sensor can detect the tension of the mulch film in real time. If the detected signal is lower than the preset value, indicating that the mulch film is too loose, the controller controls the adjusting cylinder to extend to increase the tension of the mulch film; if the detected signal is higher than the preset value, indicating that the mulch film is too tight, the controller controls the adjusting cylinder to shorten to reduce the tension of the mulch film. This ensures that the mulch film is evenly and uniformly covered on the land during the mulching process, improving the quality of mulching. Attached Figure Description

[0031] This application discloses an electrically controlled ridging and mulching machine.

[0032] Reference Figure 1 An electrically controlled ridging and mulching machine includes a vehicle body 1, a frame 2, a mulching mechanism, and a soil covering mechanism. The vehicle body 1 includes a walking mechanism, which can be a tracked walking mechanism to facilitate movement on the field. The vehicle body 1 includes a control system, which includes a controller. The frame 2 is mounted on the vehicle body 1.

[0033] Reference Figure 1and Figure 2 The film coating mechanism includes a film coating roller 31 and a film pressing roller 32, which are rotatably mounted on the frame 2.

[0034] Reference Figure 2 The frame 2 includes a fixed frame 21 and a movable frame 22. The movable frame 22 is configured as a movable arm. The fixed frame 21 is fixedly mounted on the vehicle body 1. The movable frame 22 is hinged to the end of the fixed frame 21 away from the vehicle body 1. A deflecting element 23 is provided between the fixed frame 21 and the movable frame 22 to drive the movable frame 22 to deflect around the fixed frame 21. The deflecting element 23 is a deflecting cylinder, which is hinged to the fixed frame 21. The piston rod of the deflecting cylinder is hinged to the movable arm. The soil covering mechanism includes a soil covering cutterhead 41. An installation rod 222 is provided on the movable frame 22. The soil covering cutterhead 41 is rotatably mounted on the bottom end of the installation rod 222.

[0035] The deflection cylinder can drive the movable arm to deflect upward or downward, thereby adjusting the height position of the covering cutterhead 41 and achieving the purpose of adjusting the covering depth.

[0036] Reference Figure 2 A sleeve 221 is fixedly installed on the movable frame 22. The mounting rod 222 slides vertically through the sleeve 221. An elastic element 2221 for driving the mounting rod 222 to move downward is provided between the mounting rod 222 and the sleeve. The elastic element 2221 is a compression spring. A limiting platform 2222 is fixedly installed at the bottom of the mounting rod 222. The compression spring is sleeved on the mounting rod 222. One end of the compression spring abuts against the limiting platform 2222, and the other end abuts against the sleeve 221.

[0037] Optional, refer to Figure 2 A pull rope 5 is fixedly connected to the mounting rod 222. A drive assembly 6 for driving the pull rope 5 upwards is provided on the movable frame 22. The drive assembly 6 includes a drive motor 61 and a winding wheel 62. The drive motor 61 is fixedly mounted on the movable frame 22, and the winding wheel 62 is rotatably mounted on the movable frame 22. The pull rope 5 is wound around the winding wheel 62. The drive motor 61 is a servo motor and is used to connect to the controller.

[0038] Reference Figure 2 and Figure 3 In this embodiment, a rotating shaft 7 is rotatably mounted on the movable frame 22. Since there are two covering cutterheads 41, two winding wheels 62 are correspondingly provided, and both winding wheels 62 are fixedly mounted on the rotating shaft 7. The output shaft of the drive motor 61 is fixedly connected to the rotating shaft 7. This allows the drive motor 61 to synchronously drive the two winding wheels 62 to rotate through the rotating shaft 7, thereby synchronously adjusting the height of the two covering cutterheads 41.

[0039] Specifically, refer to Figure 2A fixed rod 223 is fixedly installed on the movable arm, and a guide wheel 2231 is rotatably mounted on the fixed rod 223. The guide wheel 2231 is located directly above the mounting rod 222. The pull rope 5 passes around the guide wheel 2231 and is fixedly connected to the winding wheel 62. The drive motor 61 drives the winding wheel 62 to rotate, which in turn drives the pull rope 5 to move, thereby driving the mounting rod 222 and the soil covering cutter head 41 to move upward, so as to achieve the purpose of adjusting the height of the soil covering cutter head 41 in real time.

[0040] Reference Figure 2 The frame 2 is equipped with a tension roller 8 for contacting the lower surface of the mulch film. The frame 2 also has an adjustment assembly for adjusting the position of the tension roller 8 to regulate the tension of the mulch film. The adjustment assembly includes an adjustment cylinder 81. The adjustment cylinder 81 is fixedly mounted on the frame 2, and a mounting frame 82 is fixedly mounted on the piston rod of the adjustment cylinder 81. The tension roller 8 is mounted on the mounting frame 82.

[0041] Optionally, the mulching machine of this application also includes a film tension sensor and a controller. The film tension sensor is used to detect the tension of the mulch film and output a detection signal. The controller responds to the detection signal and controls the movement of the adjusting cylinder 81. If the detection signal is lower than a preset value, the controller controls the adjusting cylinder 81 to extend to increase the tension of the mulch film. If the detection signal is higher than the preset value, the controller controls the adjusting cylinder 81 to shorten to reduce the tension of the mulch film.

[0042] The tension sensor can detect the tension of the mulch film in real time. If the detected signal is lower than the preset value, meaning the mulch film is too loose, the controller controls the adjusting cylinder 81 to extend and increase the tension of the mulch film. If the detected signal is higher than the preset value, meaning the mulch film is too tight, the controller controls the adjusting cylinder 81 to shorten and decrease the tension of the mulch film. This ensures that the mulch film is evenly and uniformly covered on the land during the mulching process, thus improving the quality of mulching.

[0043] Optional, refer to Figure 2 The frame 2 is equipped with a limiting component 9 for contacting the mulch film on the covering roller 31. The limiting component 9 is located above the covering roller 31. Specifically, the limiting component 9 includes a pressure roller 91 and a driving component 92. The pressure roller 91 is rotatably mounted on the frame 2, and the driving component 92 drives the pressure roller 91 to press against the mulch film on the covering roller 31. The driving component 92 can be a telescopic cylinder, which is fixedly mounted on the fixed frame 21, and the pressure roller 91 is mounted on the piston rod of the telescopic cylinder. In one embodiment, the telescopic cylinder is connected to a controller. When the mulch film tension is too loose, possibly due to the covering roller 31 rotating too fast, the controller controls the telescopic cylinder to move downward, increasing the pressure of the pressure roller 91 on the mulch film on the covering roller 31, reducing the unwinding speed of the covering roller 31, thereby increasing the tension of the mulch film and improving the covering quality.

[0044] The implementation principle of this application embodiment is as follows: During the working process, the vehicle body 1 moves along the field that needs to be covered with film, the film on the film covering roller 31 is gradually unrolled, the film pressing roller 32 presses the film tightly onto the land, and the soil covering mechanism covers the film with soil to complete the film covering operation. During this process, the tension roller 8 abuts against the film, which plays the role of tensioning the film, and the adjusting component can adjust the position of the tension roller 8, thereby adjusting the tension of the tension roller 8, so as to prevent the film from being over-tensioned or loose due to changes in the driving speed of the vehicle body 1 or other factors, thus improving the film covering quality.

[0045] The tension sensor can detect the tension of the mulch film in real time. If the detected signal is lower than the preset value, indicating that the mulch film is too loose, the controller controls the adjusting cylinder 81 to extend to increase the tension of the mulch film. If the detected signal is higher than the preset value, indicating that the mulch film is too tight, the controller controls the adjusting cylinder 81 to shorten to reduce the tension of the mulch film. This ensures that the mulch film is evenly and uniformly covered on the land during the mulching process, improving the mulching quality. The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
