Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery cutting platforms, in particular to an automatic row alignment sensor installation structure for agricultural machinery cutting platforms. Background Art

[0002] With the development of agricultural mechanization, the harvesting method of agricultural production has gradually changed from manual harvesting to mechanized harvesting.

[0003] When operating a harvester's header to harvest crops such as corn, the driver needs to control the header to align with the rows, that is, the gaps in the straw divider at the operating end of the header should be aligned with the plants. This process requires the driver to concentrate highly and observe and fine-tune the direction of the header at any time, and the operation is intensive. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to reduce the operation intensity of the cutting platform on the row.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] The utility model provides an automatic row sensor installation structure for a harvesting platform of an agricultural machinery, comprising a harvesting platform body, a plurality of straw dividers extending from the working end of the harvesting platform body; a sensor fixing plate is provided at the extending end of the straw divider, a protective cover and an angle sensor are fixed on the sensor fixing plate, a rocker arm opening is provided on the side of the protective cover, the angle sensor is arranged in the protective cover, a sensor rocker arm is connected to the input shaft of the angle sensor, the sensor rocker arm extends from the rocker arm opening of the protective cover and can swing toward the harvesting platform body.

[0007] The beneficial effects of the utility model are:

[0008] With the utility model, when the cutting platform is offset, the angle sensor detects the plants through the sensor rocker arm, thereby generating an electrical signal, which is convenient for obtaining the offset state of the cutting platform, can replace the driver's observation work, and reduce the operation intensity of the cutting platform on the row; in addition, when the cutting platform body retreats, the sensor rocker arm can swing along with the remaining plants, and the rocker arm opening constrains the swing range of the sensor rocker arm, avoiding excessive swinging of the sensor rocker arm, thereby protecting the sensor rocker arm from excessive force and causing plastic deformation or fracture, and having a long service life.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the sensor rocker arm is arc-shaped and bends toward the header body.

[0011] This makes it easier for the plants to slide smoothly into the cutting table, avoiding the sensor arm from colliding with or hooking the plants and causing deformation.

[0012] Furthermore, when the sensor rocker arm swings toward the header body to the edge of the contact rocker arm opening, the sensor rocker arm is deflected 50° relative to the zero position of the angle sensor; when the sensor rocker arm swings away from the header body to the other edge of the contact rocker arm opening, the sensor rocker arm is deflected -50° relative to the zero position of the angle sensor.

[0013] The swing range of the sensor rocker arm is restricted by the rocker arm opening of the protective cover, so that the forward and backward swing range of the sensor rocker arm is within 50°, which effectively protects the sensor rocker arm from excessive swing and prolongs its service life.

[0014] Furthermore, the width of the sensor fixing plate and the width of the protective cover gradually narrow from the direction close to the crop divider to the direction away from the crop divider.

[0015] It is convenient to guide the plants into the header body to prevent the sensor fixing plate from pushing down the plants or causing its own deformation.

[0016] Furthermore, a mounting cover is provided at one end of the sensor fixing plate facing the crop divider, and the protruding end of the crop divider extends into the mounting cover and is fixedly connected to the mounting cover.

[0017] Improve the stability of the sensor fixing plate to prevent the sensor fixing plate from falling off the crop divider.

[0018] Furthermore, one end of the protective cover close to the crop divider covers the mounting cover and is fixedly connected to the mounting cover.

[0019] It is convenient to make full use of the protective cover to guide the plants, avoid the plants scratching the sensor fixing plate and the angle sensor and other structures inside the protective cover, reduce the force on the sensor fixing plate, and avoid the sensor fixing plate falling off the grain divider.

[0020] Furthermore, a conical sleeve is provided at one end of the sensor fixing plate away from the crop divider, and one end of the protective cover away from the crop divider extends into the conical sleeve.

[0021] The tip of the protective cover is fixed by a conical sleeve, which is easy to install and has good stability.

[0022] Furthermore, as an embodiment of the utility model: each of the protective covers is provided with a rocker arm opening, the rocker arm openings on any two adjacent protective covers are arranged relative to each other, and the sensor rocker arms in the two adjacent protective covers extend toward each other.

[0023] It is convenient to accurately control the plants to enter the cutting platform from the middle position between the two crop dividers, and there is no need to set a sensor rocker arm at each crop divider gap, which is convenient to reduce interference signals and easy to install.

[0024] Furthermore, as another embodiment of the utility model: rocker arm openings are opened on opposite sides of the protective cover, two angle sensors are arranged in the protective cover, and sensor rocker arms of the two angle sensors extend from the rocker arm openings in opposite directions.

[0025] It is convenient to accurately control the grain divider to enter the middle position between two rows of plants, and there is no need to modify each grain divider to install structures such as angle sensors, which is easy to install and reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] This utility model refers to Figure 1-4 .

[0034] Embodiment 1, as Figure 1-2 As shown:

[0035] The utility model provides an automatic row-aligning sensor installation structure for a harvesting platform of an agricultural machinery, comprising a harvesting platform body 1, a plurality of straw dividers 2 extending from the working end of the harvesting platform body 1; a sensor fixing plate 3 is provided at the extending end of the straw divider 2, a protective cover 4 and an angle sensor 5 are fixed on the sensor fixing plate 3, a rocker arm opening 7 is provided on the side of the protective cover 4, the angle sensor 5 is arranged in the protective cover 4, a sensor rocker arm 6 is connected to the input shaft of the angle sensor 5, the sensor rocker arm 6 extends from the rocker arm opening 7 of the protective cover 4 and can swing toward the harvesting platform body 1.

[0036] principle:

[0037] During operation, the main body 1 of the harvesting platform moves forward to harvest crops such as corn, and the straw divider 2 at the operating end first extends into the crop cluster. If the harvesting platform is aligned accurately, the plants will enter the harvesting platform from between each two adjacent straw dividers 2, and there will be no collision or only slight contact between the plants and the sensor rocker arm 6; the electrical signal of the slight rotation of the angle sensor 5 can be ignored, or the angle sensor 5 can be set to not generate an electrical signal when the rotation angle is not greater than 2°. If the harvesting platform is offset, the straw divider 2 is close to or touches the plant, and the sensor rocker arm 6 extending from the side of the protective cover 4 of the straw divider 2 is moved by the plant, so that the sensor rocker arm 6 swings toward the main body 1 of the harvesting platform, driving the input shaft of the angle sensor 5 to rotate, and the angle sensor 5 generates an electrical signal. The electrical signal can be used to prompt the harvesting platform to be skewed, which is convenient for the driver to adjust; it can also be used to input the steering controller of the agricultural machinery to feedback control the fine-tuning direction of the agricultural machinery; the steering controller is a prior art. When the harvesting platform body 1 retreats, the remaining plants between the dividers 2 drive the sensor rocker arm 6 to swing away from the harvesting platform body 1. The electrical signal of the angle sensor 5 rotating in the opposite direction can be ignored, and the angle sensor 5 can also be set to not generate an electrical signal when rotating in the opposite direction.

[0038] In summary, by adopting the utility model, when the cutting platform is offset, the angle sensor 5 detects the plants through the sensor rocker arm 6, thereby generating an electrical signal, which is convenient for obtaining the offset state of the cutting platform, can replace the driver's observation work, and reduce the operation intensity of the cutting platform on the row; in addition, when the cutting platform body 1 retreats, the sensor rocker arm 6 can swing along with the remaining plants, and the rocker arm opening 7 constrains the swing range of the sensor rocker arm 6, avoiding excessive swinging of the sensor rocker arm 6, thereby protecting the sensor rocker arm 6 from excessive force and causing plastic deformation or fracture, and having a long service life.

[0039] Furthermore, the sensor rocker arm 6 is arc-shaped and bends toward the header body 1 .

[0040] This facilitates the smooth sliding of the plant into the cutting platform, and avoids the sensor rocker arm 6 from contacting or hooking the plant and causing deformation.

[0041] Furthermore, when the sensor rocker arm 6 swings toward the header body 1 to the edge of the contact rocker arm opening 7, the sensor rocker arm 6 is deflected 50° relative to the zero position of the angle sensor 5; when the sensor rocker arm 6 swings away from the header body 1 to the other edge of the contact rocker arm opening 7, the sensor rocker arm 6 is deflected -50° relative to the zero position of the angle sensor 5.

[0042] The swing range of the sensor rocker arm 6 is restricted by the rocker arm opening 7 of the protective cover 4, so that the forward and backward swing range of the sensor rocker arm 6 is within 50°, which effectively protects the sensor rocker arm 6 from excessive swinging and prolongs its service life.

[0043] Furthermore, the width of the sensor fixing plate 3 and the width of the protective cover 4 gradually narrow from the direction close to the crop divider 2 to the direction away from the crop divider 2 .

[0044] It is convenient to guide the plants into the header body 1, and prevent the sensor fixing plate 3 from pushing down the plants or causing its own deformation.

[0045] Furthermore, a mounting cover 8 is provided at one end of the sensor fixing plate 3 facing the crop divider 2 , and the protruding end of the crop divider 2 extends into the mounting cover 8 and is fixedly connected to the mounting cover 8 .

[0046] The stability of the sensor fixing plate 3 is improved to prevent the sensor fixing plate 3 from falling off the crop divider 2 .

[0047] Furthermore, one end of the protective cover 4 close to the crop divider 2 covers the mounting cover 8 and is fixedly connected to the mounting cover 8 .

[0048] It is convenient to make full use of the protective cover 4 to guide the plants, avoid the plants scratching the sensor fixing plate 3 and the angle sensor 5 inside the protective cover 4 and other structures, reduce the force on the sensor fixing plate 3, and avoid the sensor fixing plate 3 falling off the grain divider 2.

[0049] Furthermore, a conical sleeve 9 is provided at one end of the sensor fixing plate 3 away from the crop divider 2 , and one end of the protective cover 4 away from the crop divider 2 extends into the conical sleeve 9 .

[0050] The tip of the protective cover 4 is fixed by the conical sleeve 9, which is convenient for installation and has good stability.

[0051] Furthermore, each of the protective covers 4 is provided with a rocker arm opening 7 , and the rocker arm openings 7 on any two adjacent protective covers 4 are arranged opposite to each other, and the sensor rocker arms 6 in the two adjacent protective covers 4 extend toward each other.

[0052] It is convenient to accurately control the plants to enter the cutting platform from the middle position between the two crop dividers 2, and there is no need to set the sensor rocker arm 6 at the gap between each crop divider 2, which is convenient to reduce interference signals and is easy to install.

[0054] The difference from the first embodiment is that:

[0055] Furthermore, rocker arm openings 7 are provided on opposite sides of the protective cover 4 , and two angle sensors 5 are provided inside the protective cover 4 . Sensor rocker arms 6 of the two angle sensors 5 extend from the rocker arm openings 7 in opposite directions.

[0056] It is convenient to accurately control the grain divider 2 to enter the middle position between two rows of plants, and there is no need to modify each grain divider 2 to install structures such as the angle sensor 5, which is convenient to install and reduces costs.
