[0002] The main purpose of a harvester is to harvest crops, such as wheat, rice, corn, etc. It can save a lot of manpower and time and improve harvesting efficiency. Harvesters are suitable for plains, hills, mountains and other terrains, greatly facilitating farmers' harvests.
[0003] When using a wheat harvester, it is necessary to adjust the height of the guide device so that it contacts the ground, and then start the harvester. The height that the guide device needs to maintain is generally 5-10 cm, so as to ensure that the distance between the bottom cutting knife and the ground is not too far or too close. However, the land in the farmland is not flat, and some fields inevitably have some soil slopes, and these soil slopes often require users to observe them with their naked eyes. The guide device cannot provide users with specific data, which will cause certain inconveniences when using it. For this reason, we provide a cutting guide device for a harvester to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. The utility model is equipped with components such as sensors and springs. First, the spring can push the sensor plate, and the sensor plate will shrink inward when it contacts the slope. After passing the slope, the spring will push the sensor plate out so that the sensor plate can return to its original position and continue to be used. When the sensor plate moves, the sensor will detect the position of the sensor plate and transmit the data to the user, so that the user can better adjust the position of the cutting knife. It is very convenient and solves the problem of inconvenience in use when the user has no data.
[0014] 2. The utility model provides components such as a limit shell and an electric push rod.

The electric push rod can control the retraction of the blocking block, and the limit plate is pulled back by the movement of the blocking block. The pulled back limit plate can pull the sensor plate back into the limit shell, so that the limit plate is not easy to hit other objects. It is very easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In this embodiment: the machine body 1 is the part behind the harvester's cutting knife that transports the cut crops. The machine body 1 will fix the position of the support frame 2, and will move with the support frame 2 when the machine body 1 moves. The support frame 2 will fix the position of the support rod 3, and will move with the support rod 3 when the support frame 2 moves. The limit shell 4 can rotate with the support rod 3 as the support point. The limit shell 4 will fix the position of the sensor 5, and the user can check the position of the moving object inside the limit shell 4 through the sensor 5. The limit shell 4 will fix the position of the spring 6. The limit shell 4 will limit the direction in which the sensor plate 7 can move, thereby avoiding deviation in the position of the sensor plate 7. The inner wall of the slide groove 8 is relatively smooth, so that the friction force on the limit plate 9 when moving along the slide groove 8 is smaller. The limit shell 4 will fix the position of the electric push rod 10, and will move with the blocking block 11 when the electric push rod 10 is started.
[0023] As a technical optimization solution of the utility model, the adjustment mechanism 12 includes an electric push rod 1201, which is installed on the bottom surface of the body 1, and the output end of the electric push rod 1201 is fixedly connected to a connecting block 1202.
[0024] In this embodiment: the machine body 1 will fix the position of the second electric push rod 1201, and when the second electric push rod 1201 is started, it will move with the connecting block 1202.
[0025] As a technical optimization solution of the utility model, the outer surface of the connecting block 1202 is slidably connected to the limiting block 1203 , and the outer surface of the limiting block 1203 is slidably connected to the inside of the limiting shell 4 .
[0026] In this embodiment: the limit block 1203 will limit the position to which the connecting block 1202 can move. The limit block 1203 can move under the action of external force. The movement of the limit block 1203 provides thrust for one end of the limit shell 4, so that the limit shell 4 can rotate around the support rod 3 as the axis.
[0027] As a technical optimization solution of the present invention, a sliding rod 1204 is fixedly connected to the interior of the limiting block 1203 , and an outer surface of the sliding rod 1204 is rotatably connected to the interior of the connecting block 1202 .
[0028] In this embodiment: the limit block 1203 will fix the position of the slide rod 1204. When the connection block 1202 moves downward, the slide rod 1204 will transmit the downward force to the limit block 1203, so that the limit block 1203 pushes the limit shell 4 to move.
[0029] As a technical optimization solution of the utility model, the outer surface of the limiting shell 4 is slidably connected to the inside of the support frame 2 , and the upper surface of the sensor plate 7 is slidably connected to the bottom surface of the sensor 5 .
[0030] In this embodiment: the support frame 2 will limit the position of the limiting shell 4 to avoid errors in the movement of the limiting shell 4. When the sensing plate 7 moves, it will be detected by the sensor 5, and the sensor 5 will transmit the detected data.
[0031] As a technical optimization solution of the utility model, the outer surface of the blocking block 11 contacts the outer surface of the limiting plate 9, the interior of the limiting plate 9 is slidably connected to the output end of the electric push rod 10, and a limiting groove 13 is opened inside the limiting shell 4.
[0032] In this embodiment, when the blocking block 11 is retracted by the electric push rod 10, the blocking block 11 will push the limiting plate 9 back, and the inner wall of the limiting groove 13 is relatively smooth, so other objects will experience less friction when moving on the inner wall of the limiting groove 13.
[0033] As a technical optimization solution of the utility model, the end of the spring 6 away from the limit shell 4 is fixedly connected to the outer surface of the induction plate 7, and the inner side wall of the limit groove 13 is slidably connected to the outer surface of the limit plate 9.
[0034] In this embodiment: the spring 6 provides thrust for the movement of the sensing plate 7 , and the limiting groove 13 limits the position to which the limiting plate 9 can move.
[0035] Working principle: When using the device, you first need to start the electric push rod 1201. The electric push rod 1201 will cause the connecting block 1202 to move downward. The downward movement of the connecting block 1202 will cause the slide bar 1204 to move with the limit block 1203, thereby pushing the limit shell 4 to a position parallel to the body 1. Then start the electric push rod 1201 to move the connecting block 1202 to a suitable position. Then the spring 6 will push the sensor plate 7 to a position in contact with the ground. At this time, the sensor 5 will transmit the data to the user, and the user can adjust the height of the cutting knife according to the data of the sensor 5.
[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
