Description

Technical fields:

[0001] This utility model relates to the field of contouring device technology, and in particular to the field of contouring devices with dual-mode control function. Background technology:

[0002] Currently, traditional contour-following devices used in harvesting machinery typically rely on a single-mode control method. This primarily involves direct contact between the contour-following device and the ground, combined with a control system, to detect surface features and adjust machine control. However, single-mode contour-following devices struggle to achieve precision and versatility in the harvesting process when faced with diverse contour-following harvesting requirements. Furthermore, they exhibit lag and overshoot, impacting harvesting efficiency and crop yield. Therefore, designing a contour-following device with multi-mode contour-following control capabilities to adapt to different working conditions and application needs has become a major challenge in current agricultural machinery harvesting processes.

[0003] To enhance the adaptability and flexibility of contouring devices, this invention proposes a contouring device with dual-mode contouring control. This device can switch between two different contouring modes according to different contouring operation requirements, thereby achieving more precise and efficient contouring operations. This contouring device with dual-mode control can not only meet the needs of complex soil surface conditions and dynamically changing contouring operation conditions, but also provide more stable and reliable contouring results, thus possessing high application value.

[0004] In summary, harvesting machinery without a ground contouring device cannot adjust the height of the cutting platform according to the ground conditions, resulting in inconsistent crop stubble and high loss rates after harvesting; while harvesting machinery with a single contouring function suffers from difficulties such as delayed response of the contouring device or inconvenience in turning due to continuous grounding. Utility Model Content

[0005] This invention provides a contouring device with dual-mode contouring control function to solve the problems existing in the prior art, thereby improving the performance of receiving machinery.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A contouring device with dual-mode control function, comprising a contouring mechanism, a conveying mechanism, a mode control mechanism, and a traveling chassis, wherein:

[0008] The mode control mechanism includes a first telescopic mechanism and a second telescopic mechanism;

[0009] A fixed bracket is provided on the chassis, and the tail end of the conveying mechanism is hinged to the top of the fixed bracket via a directional hinge; the second telescopic mechanism is located between the middle end of the conveying mechanism and the chassis, and all connections are hinged.

[0010] The contouring mechanism includes a contouring base plate, a front support shaft, a rear support shaft, a spring, and a torsion spring. The front support shaft is hinged to the front end of the conveying mechanism. The contouring base plate is mounted on both the front and rear support shafts. The torsion spring is mounted on the front support shaft and applies a downward force to the contouring base plate. The rear support shaft is hinged to the spring, which is hinged to one end of a first telescopic mechanism. The other end of the first telescopic mechanism is hinged to the front end of the conveying mechanism. When the first telescopic mechanism supports the conveying device and bears the weight of the machine, the second telescopic mechanism is in a floating state. At this time, the contouring base plate contacts the ground for contouring, and the first telescopic mechanism drives the conveying device to rise and fall around the universal joint to adjust the cutter height. When the second telescopic mechanism supports the conveying device, the first telescopic mechanism retracts the contouring base plate to lift it off the ground, the contouring function stops, and the second telescopic mechanism drives the conveying device to rise and fall around the universal joint to adjust the cutter height.

[0011] Preferably, a plurality of torsion springs are installed on the front support shaft of the contouring device.

[0012] Preferably, the spring length is adjustable.

[0013] Preferably, the straight-line distance between the two ends of the contouring base plate is 0.25m, and the width is 0.025m; the maximum stroke of the first telescopic mechanism and the second telescopic mechanism is 0.2m; the length of the front support shaft and the rear support shaft is 1.2m; the first telescopic mechanism supports the conveying device and bears the weight of the machine; when the second telescopic mechanism is in a floating state, the stubble height of the cutter is adjustable from 0 to 0.15m; when the second telescopic mechanism supports the conveying device, the first telescopic mechanism retracts the contouring base plate to lift it off the ground; when the contouring function stops, the stubble height of the cutter is adjustable from 0 to 0.2m.

[0014] The present invention has the following beneficial effects:

[0015] This utility model's contouring device, equipped with dual-mode contouring control, alternately and coordinately controls the support of the first and second telescopic mechanisms for the conveying device, switching contouring modes to allow the harvesting machinery to adapt to different working scenarios. When the contouring device is needed, the second telescopic mechanism is in a floating state, the contouring base plate is in contact with the ground, and the contouring function is activated. The first telescopic mechanism supports the conveying device and bears the load. At this time, the first telescopic mechanism can drive the conveying device to rise and fall to adjust the cutter height, and the machine performs harvesting operations. When the contouring device is not needed, the second telescopic mechanism ends its floating state and raises the conveying device. The first telescopic unit drives the contouring support shaft to rise, causing the contouring base plate to leave the ground, and the contouring function stops. At this time, tasks such as turning at the edge of the field can be completed. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 The contouring device of this utility model mainly consists of: a contouring base plate 3, a spring 4, a front support shaft 9, a rear support shaft 10, and torsion springs 11. The contouring base plate 3 is installed between the front support shaft 9 and the rear support shaft 10. Several torsion springs 11 are installed on the front support shaft 9. The torsion springs 11 are fixedly installed on the front support shaft 9 at equal intervals. The torsion arms of the torsion springs 11 are fixed to the top of the contouring base plate 3 and the bottom of the conveying device 7, respectively. The torsion springs 11 are in a bent state and apply a downward force to the contouring base plate 3. The spring 4 is hinged to the end of the rear support shaft 10.

[0022] The first telescopic mechanism 2 selected in this embodiment is an electric push rod, and its telescopic length is adjustable in the range of 0 to 0.2m. The second telescopic mechanism 6 selected in this embodiment has two states: free-floating length and fixed adjustable length, with an adjustable telescopic length range of 0 to 0.2m. The straight-line distance between the two ends of the contoured base plate 3 is 0.25m, and its width is 0.025m. The conveying device 7 is hinged to the traveling chassis 5 via a universal joint 8. The traveling unit in this embodiment is a tracked traveling mechanism, which bears the weight of the machine and drives the harvesting machinery to move forward, backward, and turn left and right. The cutter 1 is connected to the lower end of the conveying device 7, and the stubble height range is 0 to 0.2m. The front support shaft 9 is hinged to the conveying device 7, and its length is 1.2m. The spring 4 is hinged to the rear support shaft 10 and the first telescopic mechanism 2, and the rear support shaft 10 has a length of 1.2m. The first telescopic mechanism 2 is hinged to the conveying device 7. The second telescopic mechanism 6 is hinged to both the conveying device 7 and the traveling chassis 5. The first telescopic mechanism 2 and the second telescopic mechanism 6 alternately support the conveying device 7.

[0023] This novel contouring device has two working modes. The first mode is the contouring working mode, such as... Figure 2 As shown:

[0024] The contouring base plate 3 of the contouring device contacts the ground and supports the conveying device 7 through the first telescopic mechanism 2. The second telescopic mechanism 6 is in a floating state. The first telescopic mechanism 2 can extend and retract around the universal joint 8 to raise or lower the conveying device 7 to adjust the height of the cutter 1. The stubble height of the cutter 1 can be adjusted from 0 to 0.15m. The harvesting machinery performs contouring harvesting operations.

[0025] The second mode is the contour-following stop mode, such as... Figure 3 As shown, the second telescopic mechanism 6 lifts the conveying device 7 around the universal joint 8, causing the contouring base plate 3 of the contouring device to detach from the ground. At this time, the first telescopic mechanism 2 shortens its length, further suspending the contouring device in the air, and the contouring function stops. The second telescopic mechanism 6 supports the conveying device 7 and controls the stubble height of the cutter 1. The stubble height of the cutter 1 can be adjusted from 0 to 0.2m. The harvesting machinery completes tasks such as turning at the field head and transferring to another location.

[0026] The first telescopic mechanism 2 and the second telescopic mechanism 6 in the embodiment can alternately support the conveying device 7, forming two modes: working and non-working modes. This can better adapt to different working scenarios such as operation, turning around, and relocation, thereby improving machine performance and efficiency.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements without departing from the principle of this utility model, and these improvements should also be considered within the scope of protection of this utility model.
