Description

Technical Field

[0001] The utility model relates to the technical field of peanut harvesters, in particular to a conveying mechanism with a cleaning structure for a peanut harvester. Background Art

[0002] A peanut harvester is an agricultural machine specially used for harvesting peanuts. It can dig peanuts out of the field soil and separate the peanut fruits from impurities such as plants, soil and weeds through a series of separation, cleaning and collection devices, finally completing the peanut harvesting work and improving the efficiency and quality of peanut harvesting.

[0003] During the operation of the peanut harvester, the conveying mechanism will come into contact with a large amount of peanut plants, soil, weeds and other materials. Therefore, impurities such as soil, weeds and peanut leaves are very likely to stay in the gaps of the conveying equipment. When there are too many impurities on the surface of the conveying mechanism, the running resistance of the conveyor belt or conveyor chain will increase. Therefore, the conveying mechanism needs to be cleaned. The existing cleaning method is to use manual cleaning. The manual cleaning method is not only time-consuming and labor-intensive, but also very likely to cause safety hazards. Some peanut harvesters with a brush cleaning structure only use a brush to scrape off impurities, and the impurities will still stay on the surface of the brush and need to be cleaned manually, so the cleaning efficiency is low. To address this problem, we propose a conveying mechanism with a cleaning structure for a peanut harvester. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] As Figures 1 - 5As shown in the figure, the utility model provides a technical solution: a conveying mechanism with a cleaning structure for a peanut harvester, including a machine body 1. A conveying mechanism 2 is arranged inside the machine body 1. A shovel plate 3 is fixedly installed at the front end of the machine body 1. A fixing frame 4 is fixedly installed on the surface of the machine body 1. A control component 6 for cleaning the surface of the conveying mechanism 2 is arranged inside the fixing frame 4. The control component 6 includes: a support plate 61. A brush 62 is fixedly installed on the surface of the support plate 61. A scraper 63 is fixedly installed on the side of the support plate 61. A support block 64 is fixedly installed on the surface of the support plate 61. When the fixed rod 6511 touches the cut surface of the support block 658, the support block 658 is stressed to drive the sliding rod 656 to move horizontally in the support block 64 under the support of the spring 657. When the sliding rod 656 moves, it can move synchronously in the annular groove 655. The rotating rod 654 is stressed to drive the circular plate 651 to perform a circular motion on the surface of the support block 64, and the convex block 652 is used to continuously knock on the surface of the support plate 61, so that the fine sand and impurities adhered to the surface of the brush 62 can fall due to the force, avoiding the influence of long-term adhesion on the cleaning effect of the brush 62.

[0022] The control assembly 6 also includes a cleaning member 65, which includes: a circular plate 651, the surface of which is rotatably connected to the surface of the support block 64, the surface of which is hinged to the protrusion 652, the surface of which is fixedly connected to one side of the torsion spring 653, the other side of which is fixedly mounted on the surface of the circular plate 651, and the circular plate 651 can perform circular motion on the surface of the support block 64 when subjected to force, and continuously knock the surface of the support plate 61 through the protrusion 652. A rotating rod 654 is fixedly mounted on the surface of the circular plate 651, the rotating rod 654 penetrates the support block 64 and is rotatably connected to the support block 64, and an annular groove 655 is provided on the surface of the rotating rod 654, and the rotating rod 654 can perform circular motion in the support block 64 when subjected to force. The surface of the annular groove 655 is slidably connected to the slide bar 656. The slide bar 656 penetrates the support block 64 and is slidably connected to the support block 64. The inner wall of the support block 64 is fixedly connected to one end of the spring 657. The other end of the spring 657 is fixedly installed on the surface of the slide bar 656. When the slide bar 656 is subjected to force, it can slide in the annular groove 655 to rotate the rotating rod 654. A support block 658 is fixedly installed on the surface of the slide bar 656. The support block 658 fits the surface of the support block 64. The cross-section of the support block 658 is triangular. When the support block 658 is subjected to longitudinal resistance force, it can move laterally on the surface of the support block 64. The surface of the support block 64 is fixedly connected to the surface of the hydraulic rod 659. The hydraulic rod 659 is fixedly installed on the inner wall of the moving block 6510. The inner wall of the moving block 6510 is fixedly installed with a fixed rod 6511. The hydraulic rod 659 can push the support block 64 to move longitudinally in the moving block 6510. A through hole 5 is provided on the surface of the fixing frame 4, and a motor 6513 is fixedly installed on the surface of the fixing frame 4. The output shaft of the motor 6513 is fixedly connected to the surface of the threaded rod 6512. The threaded rod 6512 penetrates the fixing frame 4 and is rotatably connected to the fixing frame 4. The threaded rod 6512 penetrates the moving block 6510 and is threadedly connected to the moving block 6510. The surface of the moving block 6510 fits against the inner wall of the through hole 5. When the output shaft of the motor 6513 drives the threaded rod 6512 to rotate in the fixing frame 4, the moving block 6510 can move laterally in the fixing frame 4.

[0023] In the present utility model, during use, the machine body 1 uses the shovel plate 3 at the front end to produce peanuts together with the rhizomes. The excavated peanut plants and soil mixture are pushed by the excavation shovel to the conveying mechanism 2. The conveying mechanism 2 conveys the mixture backward or upward to prepare for subsequent separation operations. During this process, some relatively loose soil will naturally fall off due to the shaking and vibration during the conveying process. The conveyed peanut plants and soil mixture reach the vibrating screen. The vibrating screen is driven by a power device to generate high-frequency vibrations, which can allow fine soil particles to fall through the sieve holes, while peanut fruits, larger soil blocks, and parts of peanut plants remain on the sieve mesh. The peanut plants preliminarily separated by the vibrating screen will enter the pneumatic separation device. The pneumatic separation device consists of a blower and an air duct. The airflow generated by the blower blows through the air duct towards the peanut plants. Since impurities such as peanut leaves and weeds are lighter in weight, they will be blown away by the airflow, while peanut fruits are heavier and continue to move forward under the action of gravity, thus realizing the further separation of peanuts from light impurities. When it is necessary to clean the conveying mechanism 2, the hydraulic rod 659 is driven to push the support block 64 and the support plate 61 downward, so that the brush 62 on the surface of the support plate 61 fits the surface of the conveying mechanism 2. After fitting, the motor 6513 on the surface of the fixed frame 4 is started. When the output shaft of the motor 6513 drives the threaded rod 6512 to rotate, the moving block 6510 can move horizontally in the through hole 5. The support plate 61 and the brush 62 connected by the hydraulic rod 659 in the moving block 6510 can move horizontally on the surface of the conveying mechanism 2 to scrape off the fine sand sticking in the gaps inside the conveying mechanism 2. The scraper 63 fixed to the side of the support plate 61 can remove larger soil blocks to avoid accumulation affecting the transportation effect of the conveying mechanism 2. After cleaning, the hydraulic rod 659 is driven to drive the support block 64 and the support plate 61 upward. When the fixed rod 6511 touches the cut surface of the support block 658, the support block 658 is stressed to drive the sliding rod 656 to move horizontally in the support block 64 under the support of the spring 657. When the sliding rod 656 moves, it can move synchronously in the annular groove 655. The rotating rod 654 is stressed to drive the circular plate 651 to perform a circular motion on the surface of the support block 64, and continuously knock on the surface of the support plate 61 by using the convex block 652. Then, the fine sand and impurities sticking to the surface of the brush 62 can fall off due to the force, avoiding long-term sticking and affecting the cleaning effect of the brush 62.

[0024] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
