Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to an alfalfa stalk flattening monitoring device. Background Technology

[0002] Alfalfa, as a high-quality forage, needs to be dried in the field after harvesting to reduce moisture and facilitate baling. Flattening the stalks can damage the epidermis and shorten the path of water evaporation, so harvesting equipment with flattening function is crucial.

[0003] Currently, alfalfa harvesting mostly uses tractor-drawn mower-flatteners. The workflow is as follows: after cutting the alfalfa, the equipment conveys the hay to upper and lower flattening rollers rotating in opposite directions. The stalks are flattened through compression, accelerating subsequent drying. A typical example is a mower-flattener with announcement number CN204090551U. It is supported by a frame and equipped with upper and lower flattening rollers with interlocking herringbone grooves. A tractor is cantilevered at the top of the frame and carries a transmission device to power the lower flattening roller.

[0004] However, this type of equipment has obvious shortcomings: First, the distance between the upper and lower flattening rollers is fixed and cannot be flexibly adjusted according to the alfalfa variety, stalk thickness and other working conditions, making it difficult to adapt to the flattening requirements; Second, it lacks a distance monitoring function, so operators cannot judge the degree of flattening. Some workers may privately increase the distance in order to speed up the progress, resulting in insufficient flattening of the stalks, which not only reduces the drying efficiency, but may also cause the forage to become moldy due to residual moisture.

[0006] To address the existing problems, this utility model provides an alfalfa stalk flattening monitoring device, including an upper flattening roller and a lower flattening roller, wherein the upper flattening roller is located above the lower flattening roller, and also includes a frame, a drive assembly, an adjustment assembly and a monitoring assembly;

[0007] The frame is positioned above the upper and lower flattening rollers. The drive assembly is located at one end of the frame, and the adjustment assembly is slidably connected to the frame.

The monitoring assembly 6 is connected to the adjustment assembly 5 and the frame 3.

[0031] The drive assembly 4 includes a housing 401, the upper end of which is fixedly connected to the frame 3. A vertically rotatable shaft 402 is mounted inside the housing 401. A bevel gear a403 is fixedly connected to the shaft 402, and a bevel gear b404 is slidably connected to the shaft 402. The bevel gear b404 is located above the bevel gear a403.

The upper end of the shaft 402 passes through the housing 401 and the frame 3.

[0032] The adjustment assembly 5 includes a connecting plate 501, which is located above the frame 3. A fixed arm 502 and a slide rail 503 are fixedly connected to both ends of the connecting plate 501, respectively. Both the fixed arm 502 and the slide rail 503 are slidably connected to the frame 3. The lower end of the slide rail 503 is slidably connected inside a sliding sleeve 504. The side end of the sliding sleeve 504 is fixedly connected to the housing 401. A fixed sleeve plate 505 is connected to the connecting shaft 407 outside the driven bevel gear b406. A lever plate 506 is connected to the rotating shaft 402 above the bevel gear b404. Both the fixed sleeve plate 505 and the lever plate 506 are fixedly connected to the portion of the slide rail 503 outside the sliding sleeve 504. A lead screw 507 is threadedly connected to the middle position of the connecting plate 501, and the lower end of the lead screw 507 is rotatably connected to the frame 3.

[0033] It should be noted that a bearing is installed between the dial plate 506 and the rotating shaft 402. This bearing is a bearing with a keyway on the inner ring, and the keyway of the bearing can be adapted to the guide protrusion 4021 on the rotating shaft 402.

[0034] The monitoring component 6 includes a protective shell 601, which is fixedly connected to the side of the connecting plate 501. A sensor 602 is fixedly connected to the upper part of the inner side of the protective shell 601. A reflector 603 is disposed inside the protective shell 601 below the sensor 602. A support rod 604 is slidably connected to the bottom of the protective shell 601. The upper end of the support rod 604 is fixedly connected to the reflector 603, and the lower end is fixedly connected to the upper surface of the frame 3.

[0035] The rotating shaft 402 is provided with a guide protrusion 4021, and the inner wall of the bevel gear b404 is provided with a keyway 4041 that matches the guide protrusion 4021.

[0036] The lower end of the fixed arm 502 is rotatably connected to the other end of the lower pressing flat roller 2.

[0037] The fixed arm 502 has a slider 5021 fixedly connected to its side, and the slider 5021 is slidably connected to the side wall of the frame 3 away from the drive assembly 4.

[0038] Among them, sensor 602 integrates a wireless transmission module, which is used to wirelessly transmit the detected spacing information to an external mobile receiving terminal.

[0039] Working principle: During the spacing adjustment stage, the operator drives the connecting plate 501, which is threadedly connected to the connecting rod 507 in the adjustment component 5, to move vertically along the frame 3 by rotating the lead screw 507 in the adjustment component 5. The fixed arms 502 at both ends of the connecting plate 501 and the slide rail 503 will move synchronously, and drive the dial plate 506 and the fixed sleeve plate 505 to move in the same direction. When the slide rail 503 and the fixed arm 502 move upward, the fixed sleeve 505 and the fixed arm 502 drive the upper flat roller 1 to move upward through the connecting shaft 407. At the same time, the driven bevel gear b406 pushes the bevel gear b404 to slide upward along the rotating shaft 402, which ultimately increases the distance between the upper flat roller 1 and the lower flat roller 2. When the slide rail 503 and the fixed arm 502 move downward, the lever 506 pushes the bevel gear b404 to slide downward along the rotating shaft 402. At the same time, the fixed sleeve 505 and the fixed arm 502 drive the upper flat roller 1 to move downward, which ultimately reduces the distance between the upper flat roller 1 and the lower flat roller 2, thus adapting to different working conditions.

[0040] After the spacing is adjusted, the stalk flattening stage begins. At this time, an external power device is connected to the upper end of the rotating shaft 402 to drive the rotating shaft 402 to rotate. The bevel gears a403 and b404 on the rotating shaft 402 will rotate synchronously and drive the driven bevel gears a405 and b406 that mesh with them to rotate in the opposite direction. Then, the driven bevel gears a405 and b406 drive the upper flattening roller 1 and the lower flattening roller 2 to rotate in opposite directions through the connecting shaft 407, so as to squeeze and flatten the alfalfa stalks conveyed between the two rollers, thus realizing the squeezing operation.

[0041] Throughout the flattening process, the monitoring component 6 is always in real-time monitoring and moves synchronously with the adjusting component 5: when the adjusting component 5 moves the connecting plate 501, the protective shell 601 moves up and down synchronously with the connecting plate 501, and its bottom slides along the support rod 604. During this process, the relative distance between the sensor 602 and the reflector 603 changes. The sensor 602 sends a signal to the reflector 603 and receives the reflected signal, calculates the real-time distance between them, and then sends the calculated distance data to an external mobile receiving terminal through the integrated wireless transmission module. After the terminal converts the data, it feeds back the actual distance between the upper flattening roller 1 and the lower flattening roller 2 to the management personnel, realizing real-time monitoring of the flattening degree.

[0042] It should be noted that the sensor 602 directly detects the distance between itself and the reflector 603, not the actual distance between the upper flat roller 1 and the lower flat roller 2. The actual distance data of the upper flat roller 1 and the lower flat roller 2 can only be obtained after conversion by the terminal, and this is also the data presented to the management personnel by the terminal.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
