Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment, and in particular to an adjustable cutting platform for a high-efficiency rapeseed harvester. Background Technology

[0002] In today's rapidly developing agricultural mechanization, rapeseed harvesters, as key equipment for rapeseed harvesting, directly affect the yield and profitability of rapeseed cultivation through their performance and efficiency. Traditional rapeseed harvesters often face problems such as fixed cutting blade height and poor adaptability during operation. Because rapeseed grows at varying heights in different regions and among different varieties, a fixed cutting blade height often fails to meet the cutting needs of different crop heights. This can not only lead to missed cuts, affecting harvesting efficiency, but also potentially damage the crop roots due to over-cutting, impacting subsequent growth and yield. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an adjustable cutting platform for a high-efficiency rapeseed harvester.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] The cutting table assembly includes a motor, a connecting shaft, a limiting plate, a cutting blade, a moving block, a lead screw, a driven gear, a driving gear, a rotating rod, and a mounting frame. The mounting frame is fixedly installed between the two protective plates. The mounting frame has a U-shaped structure, and through slots are provided on opposite sides of the interior of the mounting frame. The interior of the mounting frame is a hollow structure.

[0008] As a preferred embodiment of this utility model, the motor is installed on one side of the top of the mounting bracket, the rotating rod is fixedly installed on the rotating shaft of the motor, the other end of the rotating rod is rotatably connected to the inner wall of the other side of the mounting bracket, and the drive gear is fixedly installed on both sides of the outer side of the rotating rod.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] In the attached diagram, all identical reference numerals refer to the same components.

[0023] like Figure 1-4 As shown, this utility model provides an adjustable cutting platform for a high-efficiency rapeseed harvester, comprising:

[0024] Two protective plates 1, a connecting plate 2 is fixedly installed between the two protective plates 1, and a connecting seat 3 is installed on the rear side of the connecting plate 2;

[0025] The cutting table assembly 4 includes a motor 401, a connecting shaft 402, a limiting plate 403, a cutting blade 404, a moving block 405, a lead screw 406, a driven gear 407, a driving gear 408, a rotating rod 409, and a mounting frame 4010. The mounting frame 4010 is fixedly installed between two protective plates 1. The mounting frame 4010 has a U-shaped structure, and through slots 5 are provided on opposite sides of the interior of the mounting frame 4010. The interior of the mounting frame 4010 is a hollow structure.

[0026] Furthermore, a motor 401 is installed on one side of the top of the mounting bracket 4010, and a rotating rod 409 is fixedly installed on the rotating shaft of the motor 401. The other end of the rotating rod 409 is rotatably connected to the inner wall of the other side of the mounting bracket 4010, and a drive gear 408 is fixedly installed on both sides of the outer side of the rotating rod 409.

[0027] Furthermore, both sides of the mounting bracket 4010 are provided with lead screws 406. The bottom of the lead screws 406 is rotatably connected to the bottom wall of the mounting bracket 4010. The top of the lead screws 406 is fixedly installed with driven gears 407, which mesh with driving gears 408.

[0028] Furthermore, movable blocks 405 are rotatably mounted on both sides of the connecting shaft 402, and a cutting blade 404 is fixedly mounted on the outside of the connecting shaft 402. Limiting plates 403 are fixedly mounted on both sides of the cutting blade 404.
