Description

Technical Field

[0001] This invention belongs to the field of forage harvesting technology, and in particular relates to a highland forage harvesting device that can harvest dumped forage. Background Technology

[0002] In high-altitude areas, due to the special geographical and climatic conditions, forage harvesting faces a series of unique challenges. In particular, forage in high-altitude areas is often knocked down by natural factors such as strong winds and snow accumulation, which makes it impossible for traditional forage harvesting equipment to complete the harvesting task efficiently. To address this, high-altitude forage harvesting equipment has emerged, which is specially designed for the unique climate and terrain characteristics of high-altitude areas. It can effectively cope with severe weather conditions and ensure the smooth progress of forage harvesting.

[0003] The prior art discloses an invention patent with application number CN118575651B, which discloses an automatic forage harvesting device. Its basic description includes: a frame, a cutting component, and a recycling component. The frame has a collection chamber with a roller inside. The cutting component is rotatably connected to the frame and is used to cut forage. The recycling component includes a transmission belt, push plates, a rotating shaft, a lever, a limiting plate, and a roller. The transmission belt is rotatably connected to the bottom of the frame. Multiple push plates are spaced apart on the transmission belt. The rotating shaft is rotatably fitted onto the frame and located beside the transmission belt. The lever is fixedly connected to the rotating shaft. The limiting plate is located between the rotating shaft and the transmission belt. A receiving platform is provided between the rotating shaft and the frame. The roller is located above the receiving platform and rotatably fitted with the frame. A connecting opening is provided at the bottom of the frame, connecting to the interior of the frame. This automatic forage harvesting device can recover forage that has not been harvested due to dumping, improving forage harvesting efficiency and reducing waste.

[0004] However, in practice, some problems still exist:

[0005] 1. Traditional equipment, when operating in areas with complex geological conditions, lacks integrated geological monitoring or early warning functions. The equipment often relies on the operator's experience to assess ground conditions. In unstable or pitted areas, the equipment may enter dangerous zones without warning, and operators may unknowingly allow the equipment to enter hazardous areas, leading to equipment damage or even accidents. This is especially true in high-altitude regions, where ground subsidence or loose soil can easily cause equipment to become stuck without prior warning, increasing operational risks.

[0006] 2. Traditional forage harvesting equipment usually drives the mowing device through a transmission system driven by rollers. However, these devices do not fully consider obstacles that may appear in plateau terrain (such as rocks, soil, etc.). When encountering obstacles, traditional equipment usually does not have an effective debris removal device, and the equipment may stop or be damaged. When too many obstacles accumulate, the equipment may need to stop to remove them, wasting a lot of time and manpower and affecting the efficiency of continuous operation.

[0007] Based on this, the present invention designs a highland forage harvesting device that can harvest dumped forage to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to address the problems of traditional equipment lacking early warning functions under complex geological conditions, relying on operational experience, easily entering dangerous areas, increasing the risk of equipment damage and accidents, especially in plateau areas, and failing to consider plateau obstacles and lacking waste removal devices.

[0031] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0032] 1. In this invention, through the geological early warning mechanism, when the user starts the highland forage harvester and begins harvesting forage, the harvesting device will cut the forage and feed it into the highland forage harvester. During movement, the base will descend due to the compression of the spring, causing the rollers to make close contact with the ground. If the highland forage harvester enters a pit or soft soil area, the excessive descent of the base will trigger the movement of the trigger plate. The trigger rod at the bottom of the trigger plate will press the push-button trigger switch, which will activate the audible and visual alarm to alert the user. If the ground subsidence is deep, the user is reminded to get out of the vehicle to check. This safety warning mechanism effectively prevents the highland pasture harvester from entering dangerous areas, ensuring the safety of the harvester and the operator. If there are rocks or soil in front, the weight of the rocks will push the guide plate to move, which in turn will move the limit guide plate. The movement of the limit guide plate will compress the buffer spring. If the rocks are heavy, the limit guide plate will continue to apply pressure, and the trigger rod two will activate the sound and light alarm through the pressure-press trigger switch one, issuing a warning signal to remind the user to pay attention to obstacles in front.

[0033] 2. In this invention, through the geological early warning mechanism, when encountering shallow pits on the ground, the user can activate the electric push rod. The output end of the push rod drives the pressure controller to descend, thereby applying pressure to the bearing rod and increasing the contact force between the base and the ground. Through this adjustment, the roller can make hard contact with the ground, increasing the stability of the plateau forage harvester and ensuring that the plateau forage harvester can travel smoothly in soft soil, pits, or irregular terrain. This design improves the adaptability of the plateau forage harvester in complex terrain.

[0034] 3. In this invention, the set debris removal mechanism drives a transmission wheel to rotate when the harvester's rollers rotate continuously. This drives another transmission wheel via a transmission belt, and then a lead screw drives a limiting ball to move. The movement of the limiting ball causes the telescopic plate to move along the direction of the limiting rod. When one end of the telescopic plate approaches the magnetic block, the magnetic force of the magnetic plate attracts the magnetic block, causing the striking rod to move. The striking rod compresses the reset spring. As the magnetic plate moves away, the reset spring pushes the striking rod to reset. The other end of the striking rod applies pressure to the rubber plate, which strikes the guide plate, generating vibration. The force of the vibration can remove stones or debris accumulated in front of the guide plate, thereby accelerating the debris removal function of the guide plate. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1-9 The present invention provides a technical solution: a plateau forage harvesting device that can harvest dumped forage, including a plateau forage harvester body 1, a geological early warning mechanism 4 on the front of the plateau forage harvester body 1, and a debris removal mechanism 6 on the inner side of the plateau forage harvester body 1.

[0048] The geological early warning mechanism 4 includes a compression spring 418, a roller 411, a push-button trigger switch 412 and a push-button trigger switch 420. The bottom end of the compression spring 418 is fixedly connected to a base 410, the bottom end of the base 410 is rotatably connected to the roller 411, a trigger plate 409 is fixedly connected to one side of the base 410, and a trigger rod 419 is fixedly connected to the bottom end of the trigger plate 409.

[0049] The impurity removal mechanism 6 includes a magnetic suction plate 606, a magnetic suction block 608, a return spring 612, a sleeve 601, and a striking rod 613. The striking rod 613 is vertically slidably connected to the middle of the sleeve 601. The magnetic suction block 608 is fixedly connected to one end of the striking rod 613. The magnetic suction plate 606 is provided on one side of the magnetic suction block 608. The return spring 612 is sleeved in the middle of the striking rod 613.

[0050] Specifically, such as Figures 4-6As shown, a harvesting device 3 is connected to the center of the front of the highland pasture harvester body 1. Two protective side plates 2 are fixedly connected to the front of the highland pasture harvester body 1, and a protective box 408 is fixedly embedded in the center of each of the two protective side plates 2.

[0051] Among the aforementioned components, the two protective side plates 2 not only enhance the structural strength of the plateau pasture harvester body 1, but also effectively protect the harvesting device 3 and other important components from impacts or damage from external objects (such as stones, debris, etc.).

[0052] Specifically, such as Figures 4-6 As shown, an electric push rod 414 is fixedly connected to the inner wall of the protective box 408. A pressure controller 415 is fixedly connected to the output end of the electric push rod 414. The pressure controller 415 is electrically connected to the electric push rod 414. A trigger plate 409 is vertically slidably connected to the inner wall of the protective box 408. A push-type trigger switch 420 is fixedly connected to one side of the inner wall of the protective box 408.

[0053] Among the aforementioned components, the pressure controller 415 can automatically adjust the pressure according to different geological conditions encountered by the highland forage harvester 1 during operation, ensuring stable operation of the highland forage harvester 1 in soft soil, potholes, or irregular terrain. The push-button trigger switch 420 works in conjunction with the trigger plate 409. When the position of the trigger plate 409 changes, the push-button trigger switch 420 will be pressed to activate the corresponding alarm or safety mechanism, promptly issuing a warning signal to the operator. For example, when the highland forage harvester 1 enters a soft soil or pothole area, the push-button trigger switch 420 will activate the audible and visual alarm 413 to remind the user to check the ground conditions and take necessary actions to ensure the safe operation of the highland forage harvester 1. The specific model of the electric push rod 414 is Linak LA31, and the specific model of the pressure controller 415 is Parker P4 Series.

[0054] Specifically, such as Figures 4-6 As shown, a limiting ring 416 is fixedly connected to the inner wall of the protective box 408. A compression spring 418 is fixedly connected to the bottom end of the limiting ring 416. A bearing rod 417 is inserted inside the compression spring 418. The bottom end of the bearing rod 417 is fixedly connected to the top end of the base 410.

[0055] Among the aforementioned components, the support rod 417 can automatically adjust the height and position of the base 410 according to the elastic force of the compression spring 418, thereby ensuring that the roller 411 always maintains optimal contact with the ground and improving the adaptability of the plateau pasture harvester body 1 under different geological conditions.

[0056] Specifically, such as Figures 4-6As shown, a limiting guide plate 402 is slidably connected to the inner side of the protective side plate 2. A flow guide plate 401 is fixedly connected to one end of the limiting guide plate 402, and a filter rod 5 is fixedly connected to the bottom end of the flow guide plate 401.

[0057] Among the aforementioned components, the deflector 401 is primarily used to guide and divert debris, stones, or grass clippings generated during operation, preventing their accumulation in critical areas of the highland forage harvester body 1. The filter rod 5 further cleans or filters debris in the area of ​​the deflector 401, ensuring the cleanliness and operational efficiency of the highland forage harvester body 1. The filter rod 5 effectively blocks larger stones or debris, preventing them from entering sensitive components of the highland forage harvester body 1.

[0058] Specifically, such as Figures 4-6 As shown, a buffer spring 403 is fixedly connected to the other end of the guide plate 401, and a trigger rod 404 is fixedly connected to the middle of the other end of the guide plate 401. A push-button trigger switch 420 is provided on one side of the trigger rod 404. The push-button trigger switch 420 is fixedly connected to the inner wall of the protective side plate 2. One end of the buffer spring 403 is fixedly connected to the top of the inner wall of the protective side plate 2. An audible and visual alarm 413 is fixedly connected to the outer wall of the protective box 408. Both the push-button trigger switch 412 and the push-button trigger switch 420 are electrically connected to the audible and visual alarm 413.

[0059] Among the aforementioned components, the buffer spring 403 plays a role in shock absorption and impact reduction during the operation of the highland forage harvester body 1. When the highland forage harvester body 1 encounters large obstacles or uneven ground, the buffer spring 403 can effectively absorb the resulting impact force, reducing damage to the structure of the highland forage harvester body 1. The trigger rod 404 is linked with the push-button trigger switch 412. When the guide plate 401 is displaced or subjected to external force, the trigger rod 404 will trigger the push-button trigger switch 412. Through its connection with the push-button trigger switch 412, the trigger rod 404 can activate the highland forage harvester body 1. When the machine body 1 encounters a large obstacle or excessive vibration, it issues a warning signal to ensure that the plateau forage harvester body 1 responds in a timely manner and avoids damage or malfunction of the plateau forage harvester body 1. The audible and visual alarm 413 is used to issue a warning when the plateau forage harvester body 1 encounters an abnormal situation, ensuring that the operator can receive timely feedback and take necessary measures. The sound and light signals can attract the operator's attention in noisy or poorly lit working environments, avoiding damage to the plateau forage harvester body 1 or safety accidents due to negligence. The specific models of the push-button trigger switch 412 and the push-button trigger switch 420 are Omron D4N, and the specific model of the audible and visual alarm 413 is Parker 881G.

[0060] Specifically, such as Figure 3 and Figures 5-9 As shown, the inner side of the limiting guide plate 402 is provided with two transmission wheels 603, and a transmission belt 602 is sleeved between the two transmission wheels 603. One of the transmission wheels 603 is rotatably connected to the outer side of the base 410, and the central axis of one of the transmission wheels 603 passes through the base 410 and is fixedly connected to the central axis of the roller 411. The other transmission wheel 603 is rotatably connected to the inner wall of the protective side plate 2.

[0061] In the above-mentioned components, two drive wheels 603 are used to provide power transmission and enable the various components of the plateau pasture harvester body 1 to work together efficiently. The two drive wheels 603 are connected by a drive belt 602.

[0062] Specifically, such as Figure 3 and Figures 5-9 As shown, a pretensioning wheel 405 is provided on the inner side of the transmission belt 602. The top end of the pretensioning wheel 405 is attached to the inner wall of the transmission belt 602. The bottom end of the pretensioning wheel 405 is rotatably connected to a limit support 406. The limit support 406 is slidably connected to the inner wall of the protective side plate 2. A pretensioning spring 407 is fixedly connected to the middle of the inner wall of the protective side plate 2. The top end of the pretensioning spring 407 is fixedly connected to the bottom end of the limit support 406.

[0063] In the aforementioned components, a pretensioning wheel 405 is provided on the inner side of the transmission belt 602. The function of the pretensioning wheel 405 is to maintain the tension of the transmission belt 602 and ensure the smooth operation of the transmission system. The top of the pretensioning wheel 405 is in close contact with the inner wall of the transmission belt 602. Through precise pressure adjustment, the transmission belt 602 is kept at an appropriate tension to prevent problems such as loosening or slippage of the transmission belt 602 during operation. The sliding connection method allows the limiting support 406 to slide freely on the inner wall of the protective side plate 2. This design allows the tension of the pretensioning wheel 405 to be easily adjusted according to the working needs of the plateau pasture harvester body 1, adapting to different working environments or load changes.

[0064] Specifically, such as Figure 3 and Figures 5-9 As shown, a fixed plate 610 is fixedly connected to the inner side of the guide plate 401, and a lead screw 604 is rotatably connected to the inner side of the fixed plate 610. One end of the lead screw 604 is rotatably connected to the inner side of another transmission wheel 603. A limit rod 609 is fixedly connected to the middle of the inner side of the fixed plate 610. Two limit balls 605 are provided on the inner side of the fixed plate 610. One limit ball 605 is threadedly connected to the lead screw 604, and the other limit ball 605 is slidably connected to the outer wall of the limit rod 609. A telescopic plate 607 is fixedly connected to the top of the two limit balls 605, and a magnetic plate 606 is fixedly connected to one end of the telescopic plate 607.

[0065] In the aforementioned components, the connection between the telescopic plate 607 and the limiting ball 605 ensures that the telescopic plate 607 can move precisely within a specified range, avoiding deviations caused by inaccurate positioning during operation. The magnetic plate 606 is used to magnetically connect with the magnetic block 608. Through its magnetic connection with the magnetic block 608, the magnetic plate 606 can achieve automated adsorption.

[0066] Specifically, such as Figure 3 and Figures 5-9 As shown, the sleeve 601 is fixedly connected to the inner wall of the guide plate 401, the magnetic block 608 and the magnetic plate 606 are magnetically attracted to each other, and a rubber plate 611 is fixedly connected to one end of the striking rod 613.

[0067] In the aforementioned components, a rubber plate 611 is fixedly connected to one end of the striking rod 613. The function of the rubber plate 611 is to generate vibration by striking the guide plate 401 to help clear stones, debris, or soil accumulated in front of the guide plate 401. The design of the rubber plate 611 can reduce the direct impact force and avoid damage to the guide plate 401. At the same time, the use of rubber material can effectively absorb some of the impact force, making the vibration more stable and avoiding excessive vibration from causing unnecessary impact on other components of the plateau pasture harvester body 1.

[0068] Working principle and usage: When the user starts the highland forage harvester body 1 and begins harvesting forage, the harvesting device 3 of the highland forage harvester body 1 will cut the forage and feed it into the highland forage harvester body 1. During the movement of the highland forage harvester body 1, the compression spring 418 will act on the base 410, causing the base 410 to descend and making the roller 411 in close contact with the ground. If the vehicle encounters potholes or areas with soft soil during travel, the base 410 may descend too much due to the action of the compression spring 418, causing the base 410 to move the trigger plate 409. The trigger rod 419 at the bottom of the trigger plate 409 will press the push-button trigger switch 420. After the push-button trigger switch 420 is activated, the audible and visual alarm will sound. 413 immediately issues an alarm, reminding the user that the ground has collapsed deeply and that it is necessary to get off the vehicle to check the ground conditions to ensure the safe passage of the highland forage harvester body 1. In shallower potholes, the user can activate the electric push rod 414. The output end of the electric push rod 414 will drive the pressure controller 415 to descend. The bottom end of the pressure controller 415 applies pressure to the support rod 417, thereby making the base 410 more firmly in contact with the ground. In shallower potholes, the user can activate the electric push rod 414. Through this adjustment, the roller 411 can form a hard contact with the ground, ensuring that the highland forage harvester body 1 can still pass smoothly in complex terrain. If there are rocks or accumulated soil ahead... The weight of the stone will push the guide plate 401 to move, which in turn will drive the limit guide plate 402 to move. The movement of the limit guide plate 402 will compress the buffer spring 403. If the stone is heavy, the limit guide plate 402 will continue to apply pressure, and the trigger rod 404 will activate the sound and light alarm 413 by pressing the push-button trigger switch 412 to issue a warning signal to remind the user to pay attention to the obstacle in front. In addition, when the roller 411 of the highland pasture harvester body 1 continues to rotate, it will drive one of the transmission wheels 603 to rotate. This transmission wheel 603 drives the other transmission wheel 603 to rotate through the transmission belt 602, which in turn drives the lead screw 604 to rotate. The rotation of the lead screw 604 will drive the limit ball 605 to move, and the limit ball 605 will cause the telescopic plate 607 to move along the path. Moving in the direction of the limiting rod 609, when one end of the telescopic plate 607 approaches the magnetic block 608, the magnetic force of the magnetic plate 606 will attract the magnetic block 608. After the magnetic block 608 is attracted, the magnetic force will drive the striking rod 613 to move. The movement of the striking rod 613 will compress the return spring 612. As the magnetic plate 606 moves, the magnetic force disappears, and the return spring 612 will push the striking rod 613 to return to its original position. The other end of the striking rod 613 will apply pressure to the rubber plate 611, and the rubber plate 611 will strike the guide plate 401, generating vibration. The guide plate 401 is set as an inclined structure. Under the action of vibration, the stones accumulated in front of the guide plate 401 will be effectively removed, thereby accelerating the impurity removal function of the guide plate 401. In complex terrain or environments with many stones,It effectively removes obstacles, preventing the highland pasture harvester from stalling due to encountering rocks or other obstacles during operation, ensuring continuous operation and improving overall operating time and efficiency.
