Abstract
Description
Technical Field
[0001] This utility model relates to the field of harvester technology, and more specifically, to a longitudinal shaft harvester drum. Background Technology
[0002] When a combine harvester harvests wheat, it cuts the wheat stalks with blades, then rolls the wheat into the machine. The wheat is then conveyed through a series of processes, separating and discharging the wheat. One of the key components of a combine harvester is the drum. When the wheat is conveyed to the drum, it is separated and discharged by the drum, separating the wheat ears from the stalks before subsequent operations can be carried out.
[0003] Since most current harvester drums are hollow cylinders, after separating the wheat ears and straw at the position of the wheat conveyor drum, the straw tends to rotate with the drum, affecting the efficiency of straw discharge. As more wheat continues to enter the drum, if the straw at the drum position is not discharged in time, it will cause material blockage, resulting in a large accumulation of straw at the drum position, preventing normal operation and making the machine unusable. Therefore, a longitudinal shaft harvester drum is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a longitudinal axis harvester drum that overcomes or at least partially solves the above technical problems.

[0013] In a preferred embodiment, an n-shaped tooth is fixedly installed on the outer surface of the rectangular plate. Both the n-shaped tooth and the R-shaped tooth are provided in multiples, and the n-shaped tooth is positioned between two R-shaped teeth.
[0014] In a preferred embodiment, both the n-shaped teeth and the R-shaped teeth are hollow inside, and the n-shaped teeth and the R-shaped teeth are set to be perpendicular to each other.
[0015] In a preferred embodiment, the upper surface of the rectangular plate is also fixedly fitted with mounting teeth, and threaded rods are welded to the inner side of the mounting teeth, with six threaded rods to improve the wheat processing effect.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Example
[0028] Reference Figures 1-4 This utility model provides a technical solution: a longitudinal axis harvester drum, including a round shaft 1 and a drum assembly 3, with a conical block 2 installed at one end of the round shaft 1. The drum assembly 3 includes a disc 31, which is stably installed on the outer surface of the round shaft 1. A rectangular plate 311 is stably installed on the outer surface of the disc 31. R-shaped teeth 32 are installed on the upper surface of the rectangular plate 311. A threaded rod 321 is installed at one end of the rectangular plate 311. An actuating rod 33 is stably installed on the outer surface of the round shaft 1, with one end of the actuating rod 33 positioned below the rectangular plate 311.
[0029] In a preferred embodiment, a spiral plate 4 is provided on the outer surface of the conical block 2 for feeding and rolling the wheat. The device has a spiral plate 4 installed on the outside of the conical block 2. In actual use, the device will be driven to rotate continuously, which will cause the spiral plate 4 to rotate continuously. Under the continuous rotation of the spiral plate 4, the wheat will be quickly rolled into the position of the rectangular plate 311 for processing.
[0030] In a preferred embodiment, a circular plate 5 is fixedly mounted on one side of the conical block 2. The diameter of the circular plate 5 is set to 360 mm, and the diameter of the disc 31 is set to 388 mm.
[0031] This device is designed for rapid straw discharge. Several n-shaped teeth 6 and R-shaped teeth 32 are fixedly installed on the outer surface of a rectangular plate 311. The n-shaped teeth 6 are positioned between two R-shaped teeth 32. Both the n-shaped teeth 6 and R-shaped teeth 32 are hollow and perpendicular to each other. By using these teeth on the outer surface of the rectangular plate 311, they continuously push the straw during discharge, achieving rapid discharge and ease of use. Several actuating rods 33 are evenly distributed on the outer surface of a circular shaft 1. The distance between the top of the actuating rod 33 and the bottom of the rectangular plate 311 is 5 cm. The continuous rotation of the circular shaft 1 drives the actuating rods 33 to rotate, rapidly discharging straw near the circular shaft 1, facilitating use.
[0032] The device also has mounting teeth 7 fixedly installed on the upper surface of the rectangular plate 311, and threaded rods 321 are welded to the inner side of the mounting teeth 7. There are six threaded rods 321 to improve the processing effect of wheat. The top of the mounting teeth 7 is set to be inclined, and the angle between the threaded rods 321 and the inclined part of the mounting teeth 7 is set to 60°. When the wheat enters the position of the threaded rods 321, it will be rolled by the threaded rods 321. Since the threaded rods 321 are not smooth, they can increase the friction with the straw and prevent slippage. Thus, the wheat can be quickly rolled and separated by the threaded rods 321.
[0033] Specifically, the working process or principle of a longitudinal shaft harvester drum is as follows: Since most current drums are hollow cylinders, after separating the wheat ears and straw at the position of the wheat conveyor drum, the straw easily follows the rotation of the drum, affecting the straw discharge efficiency. As more wheat continues to enter the drum, if the straw at the drum position is not discharged in time, it will cause blockage, resulting in a large accumulation of straw at the drum position, preventing normal operation and rendering the machine unusable. Therefore, this device is designed to solve this problem.
[0034] This device has R-shaped teeth 32 and n-shaped teeth 6 installed on a rectangular plate 311, and the two are set to a perpendicular state. With the rotation of this device, grass can be quickly discharged to avoid jamming. It is easy to use. Specifically, this device is installed inside a harvester. The harvester harvests wheat and conveys it to the position of this device through a chain conveyor. This device will drive the round shaft 1 to rotate through the drive equipment inside the harvester, thereby driving the entire device to rotate. The rotation of the conical block 2 drives the spiral plate 4 to rotate. The spiral plate 4 can move the wheat to the position behind the conical block 2. The rotation of the round shaft 1 will drive the rectangular plate 311 and the R-shaped teeth 32 and n-shaped teeth 6 on the rectangular plate 311 to rotate, which facilitates further processing of the wheat.
[0035] After the wheat passes through the conical block 2 and moves to the rectangular plate 311, it will be rolled into the outer and inner sides of the rectangular plate 311 by the rotation of the rectangular plate 311. At the outer side of the rectangular plate 311, the wheat will be rolled by the interaction of the threaded rod 321, the R-shaped teeth 32, and the n-shaped teeth 6. This device increases the number of threaded rods 321 from the existing three to six. The addition of threaded rods 321 increases the friction with the wheat straw, which not only improves the rolling effect of the wheat but also increases the strength of the mounting teeth 7, preventing wobbling during use. The mounting teeth 7 in this device can be used to support the threaded rods 321, but in actual use, they can also be used as a single tooth to prevent the rice from being crushed, thus meeting the requirements of use.
[0036] This device uses the position of the threaded rod 321 as the feeding zone, the middle position of the round shaft 1 as the separation zone, and the end position of the round shaft 1 as the discharge zone. After the wheat passes through the feeding zone, it will move to the separation zone. In the separation zone, the wheat will be continuously agitated by the R-shaped teeth 32 and the n-shaped teeth 6 to separate the rice and straw. To improve the separation effect, the wheat can be separated in the separation zone. As the wheat continues to move, it will move to the discharge zone. This device is also equipped with R-shaped teeth 32 and n-shaped teeth 6 in the discharge zone. Through the cooperation of the R-shaped teeth 32 and the n-shaped teeth 6, the wheat can be continuously separated, and the separated rice and straw will be discharged. The rice will be transported to the screen inside the harvester for further processing, while the straw will be discharged to the outside of the harvester.
[0037] This device has several actuating rods 33 installed on the outer surface of the circular shaft 1. During the wheat harvesting process, a large amount of wheat will enter the inner side of the rectangular plate 311 and be located outside the circular shaft 1. In order to prevent the straw from getting tangled on the circular shaft 1, actuating rods 33 are installed on the circular shaft 1. As the actuating rods 33 rotate continuously with the circular shaft 1, the wheat outside the circular shaft 1 will be agitated, causing the straw to be quickly thrown out, thus preventing the straw from getting tangled on the circular shaft 1 and improving the effectiveness of the device.
