Description
Technical Field
[0001] This utility model belongs to the field of harvester technology, specifically relating to a corn harvester turning assist device at the edge of the field. Background Technology
[0002] Corn harvesters were developed to address the problems of low efficiency and high labor intensity associated with manual corn harvesting. Research and development began in Europe and America in the mid-20th century, initially with single functions, but later integrating multiple functions and evolving towards automation and large-scale production. my country began importing and imitating corn harvesters in the 1970s, developing models adapted to small-scale planting based on national conditions, forming a multi-specification system and significantly improving harvesting efficiency.
[0003] When corn harvesters operate at night, insufficient light leads to blurred visibility at the edge of the field, making it difficult to accurately control the boundaries and increasing the risk of collisions with obstacles such as field ridges and trees. When turning, the working parts are prone to damage from scraping against hard objects at the edge of the field due to blind spots. Furthermore, uneven ground combined with poor visibility reduces the accuracy of the working parts in grasping corn, resulting in missed harvests or broken kernels. In addition, conventional spotlights are exposed to the elements and are easily damaged by dust when not in use, affecting the stability of nighttime illumination. Utility Model Content
[0004] The purpose of this utility model is to provide a corn harvester turning assist device at the edge of the field, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A corn harvester turning assist device includes a collision assembly, comprising a harvester head, a first fixed shaft fixedly connected to the side wall of the harvester head, a bushing rotatably connected to the side wall of the first fixed shaft, a steel pipe fixedly connected to the side wall of the bushing, a connecting pipe fixedly connected to the bottom of the steel pipe, a shock-absorbing base fixedly connected to the bottom of the connecting pipe, a shock-absorbing spring fixedly connected to the bottom of the shock-absorbing base, and a rocker arm fixedly connected to the bottom of the shock-absorbing spring.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0018] Example Reference Figure 1-4 This embodiment of the present invention provides a corn harvester turning assist device, comprising: The collision assembly 100 includes a harvester head 101, a first fixed shaft 102 fixedly connected to the side wall of the harvester head 101, a bushing 103 rotatably connected to the side wall of the first fixed shaft 102, a steel pipe 104 fixedly connected to the side wall of the bushing 103, a connecting pipe 105 fixedly connected to the bottom of the steel pipe 104, a shock-absorbing base 106 fixedly connected to the bottom of the connecting pipe 105, a shock-absorbing spring 107 fixedly connected to the bottom of the shock-absorbing base 106, and a rocker arm 108 fixedly connected to the bottom of the shock-absorbing spring 107. The lighting assembly 200 includes a fixed square tube 201 fixedly connected to the side wall of the harvester head 101, a servo motor 202 adapted and installed on the top of the fixed square tube 201, a spotlight protective housing 203 fixedly installed on the top of the servo motor 202, a rotating mounting plate 204 rotatably connected to the inner wall of the spotlight protective housing 203, and a spotlight 205 fixedly installed on the side wall of the rotating mounting plate 204. Specifically, the first fixed shaft 102 is fixedly connected to the side wall of the harvester head 101. The bushing 103 is sleeved on the outer wall of the first fixed shaft 102 and can rotate. The steel pipe 104 is fixedly connected to the side wall of the bushing 103. The connecting pipe 105 is connected to the steel pipe 104. The shock-absorbing base 106 is connected to the connecting pipe 105. A shock-absorbing spring 107 is provided between the shock-absorbing base 106 and the rocker arm 108 to absorb shock and prevent structural damage. The fixed square tube 201 is fixed to the side wall of the harvester head 101. A servo motor 202 is installed on the top. A spotlight protective shell 203 is installed on the top of the servo motor 202. The rotating mounting plate 204 inside the spotlight protective shell 203 rotates as the servo motor 202 does work. There are four spotlights 205, all of which are installed on the rotating mounting plate 204.
[0019] The collision assembly 100 also includes a wheel 109 rotatably connected to the side wall of the rocker arm 108, and a wheel 110 fixedly connected to the side wall of the wheel 109 by bolts. The collision assembly 100 also includes a connector 111 fixedly connected to the side wall of the steel pipe 104, and a hydraulic rod 112 rotatably connected to the side wall of the connector 111. The end of the hydraulic rod 112 is rotatably connected to a second fixed shaft 113, which is fixedly connected to the side wall of the harvester head 101.
[0020] Furthermore, the side wall of the rocker arm 108 is rotatably connected to the wheel 109, and the wheel 110 is fixed to the wheel 109 by five bolts. The connecting piece 111 is fixed to the side wall of the steel pipe 104, so that one end of the hydraulic rod 112 is rotatably connected to the connecting piece 111, and the other end of the hydraulic rod 112 is rotatably connected to the second fixed shaft 113. The second fixed shaft 113 is fixed to the side wall of the harvester head 101. During operation, the hydraulic rod 112 is used to buffer the force brought by the steel pipe 104 and to provide a certain force when it is necessary to lift the harvester head 101.
[0021] The collision assembly 100 also includes a warning plate base 114 fixedly connected to the top of the steel pipe 104, and a warning plate 115 fixedly connected to the top of the warning plate base 114.
[0022] Preferably, the warning plate base 114 and the warning plate 115 are mounted on the top of the steel pipe 104 and rotate with it, so that the driver can understand the operating position of other parts blocked by the harvester head 101 by observing the warning plate 115.
[0023] A brush is provided on the inner wall of the spotlight protective housing 203, and the rotating mounting plate 204 contacts the brush on the inner wall of the spotlight protective housing 203 when it rotates.
[0024] It should be noted that when the servo motor 202 rotates the mounting plate 204, it will come into contact with the brush on the inner wall of the spotlight protective shell 203, which will have a certain cleaning effect, keeping the surface of the spotlight clean and ensuring that the brightness meets the standard.
[0025] When in use, when encountering the edge of a field, the wheel 110 contacts the edge and is displaced downwards around the bushing 103. The warning plate 115 rises accordingly, allowing the driver to visually inspect the warning plate 115 to understand the position of the edge of the field and the condition of the wheel 110 on the ground. The shock-absorbing spring 107 buffers part of the impact force, reducing damage to parts. At this time, the harvester head 101 is higher than the edge of the field, allowing the harvester to turn without touching the edge. At night, when visibility is poor and there is a lot of dust during harvesting, the servo motor 202 works, causing the rotating mounting plate 204 to rotate. The spotlight 205, mounted on the rotating mounting plate 204, is exposed through the opening in the spotlight protective housing 203, providing auxiliary lighting to help the driver see the position of the edge of the field and the environment.
[0026] In summary, corn harvesters equipped with a field-end turning assist device offer significant advantages for nighttime operations. When the harvester touches the field edge, the wheels 110 move downwards under pressure, causing the harvester head 101 to rise, preventing direct impact and reducing the risk of damage. During turns, the harvester head 101 rises and does not contact the ground, further reducing the risk of collision and damage. The rotating mounting plate 204 and the spotlight 205 installed within it can be rotated and sealed when not in use, effectively isolating dust, ensuring lighting stability, improving field-end visibility, aiding in precise boundary control, reducing collision risks, and minimizing missed harvests and grain breakage due to poor visibility, significantly improving the efficiency and quality of nighttime operations.
