Description

Technical Field

[0001] This utility model belongs to the technical field of harvester accessories, specifically relating to a harvester header front stalk separating device. Background Technology

[0002] In the field of agricultural machinery, semi-feed harvesters are the core equipment for harvesting grains (such as rice and wheat). The crop division device in front of the cutter head directly determines the harvesting efficiency and crop integrity. The crop division device groups and guides the disorderly growing or lodged crops in the field to the crop lifter, and then the cutter cuts the root and stem parts. Finally, the crops are collected through the conveyor chain.

[0003] In the prior art, such as the Chinese utility model patent with authorization announcement number CN209403071U, a harvester header front separating rod device is disclosed, which uses a "7"-shaped separating guide rod to assist the separating device in separating entangled crops, thus solving the problem of blurred separating interface to a certain extent.

[0004] However, the angle between the dividing guide rod and the horizontal plane (e.g., 70°-80°) of this type of traditional dividing rod device is fixed. It cannot dynamically adjust the angle between the dividing guide rod and the horizontal plane according to the crop type (e.g., wheat with thicker stems, rice with thinner stems) or the degree of lodging (slightly lodged crops need to be guided gently, while heavily lodged crops need to be pulled away at a larger angle). As a result, the dividing guide rod cannot adapt well to different dividing needs. Utility Model Content

[0005] The purpose of this invention is to provide a harvester header front dividing rod device that enables the second dividing guide rod to be angled within a certain range, thereby allowing the angle between the second dividing guide rod and the horizontal plane to be adjusted according to different dividing requirements, so as to adapt to different dividing requirements.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A harvester header front divider device includes a first divider guide rod, a second divider guide rod, and a divider. The lower ends of the divider and the second divider guide rod are connected together. The first divider guide rod and the second divider guide rod are movably connected. The angle between the first divider guide rod and the second divider guide rod is adjustable.

[0008] Furthermore, the front end of the first dividing guide rod and the upper end of the second dividing guide rod are hinged together, and a first electric telescopic rod is hinged to the first dividing guide rod, with the piston rod of the first electric telescopic rod and the second dividing guide rod hinged together.

[0009] Furthermore, a sliding rod is slidably connected to the lower part of the second dividing guide rod, the sliding rod is connected to the divider, and a telescopic adjustment structure that is driven and connected to the sliding rod is installed on the second dividing guide rod.

[0010] Furthermore, the telescopic adjustment structure includes a second electric telescopic rod fixedly connected to the rear side of the second dividing guide rod, and the lower ends of the piston rod and the slide rod of the second electric telescopic rod are fixedly connected.

[0011] Furthermore, an extension rod is fixedly connected to the lower end of the slide rod, and an angle adjuster is fixedly connected to the extension rod. The divider is connected to the extension rod through the angle adjuster.

[0012] Furthermore, the angle adjuster includes a bracket body fixedly connected to the upper side of the extension rod. A worm gear body and a rotating rod are rotatably connected inside the bracket body. A worm wheel body and a rotating bracket are fixedly connected to the outer side of the rotating rod. The worm gear body and the worm wheel body are meshed together. One end of the rotating bracket is fixedly connected to the divider. A servo motor is fixedly connected to the outer side of the bracket body. The output end of the servo motor is fixedly connected to the worm gear body.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model discloses a harvester header front dividing rod device. By adjusting the angle between the first dividing rod and the second dividing rod, the angle of the second dividing rod can be adjusted within a certain range. Thus, the angle between the second dividing rod and the horizontal plane can be adjusted according to different dividing requirements to adapt to different dividing needs.

[0022] like Figures 1-4 As shown, a harvester header front divider device includes a first divider guide rod 1, a second divider guide rod 2, and a divider 4. The rear end of the first divider guide rod 1 is fixedly connected to the harvester. The divider 4 is connected to the lower end of the second divider guide rod 2. The first divider guide rod 1 and the second divider guide rod 2 are movably connected. The angle between the first divider guide rod 1 and the second divider guide rod 2 is adjustable, enabling the second divider guide rod 2 to be adjusted within a certain range. Thus, the angle between the second divider guide rod 2 and the horizontal plane can be adjusted according to different divider requirements to adapt to different divider needs.

[0023] like Figures 1-3 As shown, two dividing slopes 7 can be opened on the front side of the second dividing guide rod 2. The two dividing slopes 7 form a dividing angle to assist in the separation of crops.

[0024] like Figures 1-2 As shown, in some embodiments, the front end of the first dividing guide rod 1 and the upper end of the second dividing guide rod 2 are hinged together to enable the second dividing guide rod 2 to rotate. A first electric telescopic rod 3 is hinged to the first dividing guide rod 1. The piston rod of the first electric telescopic rod 3 and the second dividing guide rod 2 are hinged together. By activating the first electric telescopic rod 3, the second dividing guide rod 2 can be rotated to adjust the angle of the second dividing guide rod 2.

[0025] In some embodiments, the connection between the first dividing guide rod 1 and the second dividing guide rod 2 can also be achieved through a purely mechanical worm gear mechanism, thereby realizing the mechanical angle adjustment of the second dividing guide rod 2.

[0026] In some embodiments, the lower end of the second dividing guide rod 2 is directly connected to the divider 4, and the connection method can be a fixed connection.

[0027] like Figures 1-3 As shown, in some embodiments, a slide rod 5 is slidably connected to the lower part of the second dividing guide rod 2. The slide rod 5 is connected to the divider 4. A telescopic adjustment structure that is induced to extend and retract is installed on the second dividing guide rod 2 to drive the slide rod 5 to extend and retract, thereby adjusting the distance between the divider 4 and the ground. After the angle of the second dividing guide rod 2 is adjusted, the distance between the divider 4 and the ground can be adjusted.

[0028] In some further embodiments, the telescopic adjustment structure includes a second electric telescopic rod 6 fixedly connected to the rear side of the second dividing guide rod 2. The piston rod of the second electric telescopic rod 6 is fixedly connected to the lower end of the slide rod 5.

The divider 4 is connected to the extension rod 8 through the angle adjuster 9. The angle of the divider 4 can be adjusted through the angle adjuster 9, thereby adjusting the tilt angle of the divider 4 after the second dividing guide rod 2 rotates.

[0031] In some embodiments, the angle adjuster 9 includes a support body 10 fixedly connected to the upper side of the extension rod 8. A worm gear body 13 and a rotating rod 12 are rotatably connected inside the support body 10. A worm wheel body 14 and a rotating bracket 15 are fixedly connected to the outer side of the rotating rod 12. The worm gear body 13 and the worm wheel body 14 are meshed together. By rotating the worm gear body 13, the worm wheel body 14 is driven to rotate, which in turn drives the rotating bracket 15 to rotate. One end of the rotating bracket 15 is fixedly connected to the divider 4. When the rotating bracket 15 rotates, it drives the divider 4 to rotate, thereby mechanically adjusting the angle of the divider 4.

[0032] In some further embodiments, a servo motor 11 is fixedly connected to the outside of the support body 10. The output end of the servo motor 11 is fixedly connected to the worm gear body 13. By starting the servo motor 11, the worm gear body 13 can be driven to rotate.

[0033] It should be noted that a battery and a controller can be fixedly connected to the harvester.
