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] The harvester drum is installed on the harvester and used on it. The failure rate of the harvester during use directly affects the efficiency of farmers' harvesting operations. The threshing chamber of the harvester is a key part. The threshing chamber contains a high-speed rotating axial flow drum. The cleanliness of threshing mainly depends on the axial flow drum in the threshing chamber. Therefore, the quality of the drum determines the cleanliness of threshing.

[0003] Currently, when using a harvester drum, the rice is rolled into the drum by the harvester. The drum separates the rice ears from the rice stalks for harvesting. To prevent the rice ears from being crushed, the drum is equipped with teeth. However, in actual operation, it has been found that due to the continuous rotation of the drum, a large amount of rice stalks are rolled into the outside of the drum. When the amount of rice stalks reaches a certain level, it will jam the drum, preventing it from rotating normally and affecting the harvesting of rice. 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.

[0006] This utility model provides a longitudinal axis harvester drum, including a cylinder, and a spiral plate is provided on the outer surface of the cylinder;

[0007] The roller assembly includes;

[0008] A circular plate is stably mounted on the outer surface of a cylinder, and a cylindrical rod is mounted on the inner side of the circular plate.

[0009] R-shaped teeth, the R-shaped teeth are stably installed on the outer surface of the cylindrical rod, and n-shaped teeth are provided on one side of the R-shaped teeth;

[0010] A toothed plate is stably mounted on the outer surface of a cylindrical rod, and a threaded rod is stably mounted on the inner side of the toothed plate.

[0011] In a preferred embodiment, a drive shaft is mounted on one end face of the cylinder, and a mounting hole is provided at the other end of the cylinder.

[0022] 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.

[0023] Example

[0024] Reference Figures 1-4 This utility model provides a technical solution: a longitudinal axis harvester drum, including a cylinder 1 and a drum assembly 3, with a spiral plate 2 provided on the outer surface of the cylinder 1, and the drum assembly 3 including a circular plate 31, the circular plate 31 being stably installed on the outer surface of the cylinder 1, and a cylindrical rod 311 being installed on the inner side of the circular plate 31, an R-shaped tooth 32 being stably installed on the outer surface of the cylindrical rod 311, and an n-shaped tooth 321 being provided on one side of the R-shaped tooth 32, a toothed plate 33 being stably installed on the outer surface of the cylindrical rod 311, and a threaded rod 331 being stably installed on the inner side of the toothed plate 33.

[0025] In a preferred embodiment, a drive shaft 4 is installed on one end face of the cylinder 1, and a mounting hole 5 is provided at the other end of the cylinder 1. In order to facilitate the control of the rotation of the device, a drive shaft 4 is installed at one end of the cylinder 1. In actual use, the drive shaft 4 will be connected to the drive equipment inside the harvester so as to drive the device to work normally and facilitate the processing of rice.

[0026] In a preferred embodiment, there are several R-shaped teeth 32 and n-shaped teeth 321 arranged around the outside of the cylinder 1. Each R-shaped tooth 32 corresponds to one n-shaped tooth 321. The n-shaped teeth 321 are arranged perpendicular to the R-shaped teeth 32. The R-shaped teeth 32 and n-shaped teeth 321 work together to speed up the discharge of straw and prevent straw from accumulating outside the cylinder 1, which could cause material jamming. The R-shaped teeth 32 and n-shaped teeth 321 will disturb the straw during continuous rotation, preventing it from piling up and making it easier to use.

[0027] In a preferred embodiment, six threaded rods 331 are provided, and three of them are mounted on cylindrical rods 311 to enhance the sturdiness of the device and enable its stable use.

[0028] Specifically, the working process or principle of a drone testing platform is as follows: Currently, when a harvester is in use, rice is rolled into the inside of the drum, and the drum separates the rice ears and rice stalks for harvesting. To prevent the rice ears from being crushed, the drum is equipped with teeth. However, in actual operation, it has been found that due to the continuous rotation of the drum, a large amount of rice stalks are rolled into the outside of the drum. When the amount of rice stalks reaches a certain level, it will jam the drum, preventing it from rotating normally and affecting the harvesting of rice. Therefore, this device was designed to solve this problem.

[0029] This device can quickly discharge straw by stably installing R-shaped teeth 32 and n-shaped teeth 321 on the outer surface of the cylindrical rod 311. Six threaded rods 331 are installed on the cylindrical rod 311 to make the device more robust and improve its stability. Specifically, the device is installed on a harvester and controlled to rotate continuously. The harvester harvests the rice and transports it to the position of the cylinder 1. As the cylinder 1 rotates, the straw is rolled into the outside of the cylinder 1 and rotates with the cylinder 1.

[0030] When the rice grains enter the cylinder 1, the rotation of the cylinder 1 drives the R-shaped teeth 32 and n-shaped teeth 321 to rotate continuously, which breaks the rice grains and separates the ears of rice from the straw. At the same time, the continuous rotation of the R-shaped teeth 32 and n-shaped teeth 321 will quickly throw the straw out of the cylinder 1. In this device, the n-shaped teeth 321 are made of steel bars with a thickness of 8-24 mils, a height of 5-12cm, and a width of 2-6cm. The n-shaped teeth 321 and the R-shaped teeth 32 work together to improve the straw removal speed and meet the requirements.

[0031] The R-shaped teeth 32 in this device have rounded ends, which not only increases the strength of the teeth but also greatly reduces the breakage rate of grains, improving the harvesting quality of the harvester. The R-shaped teeth 32 are also more robust and durable, less prone to bending and breaking, thus extending the service life of this device.

[0032] This device has six threaded rods 331 on the cylindrical rod 311, which improves the stability of the device compared to the traditional device with only three threaded rods 331. This makes the device more stable and meets the requirements of use. When the cylinder 1 rotates, it also drives the threaded rods 331 to rotate. The threaded rods 331 quickly roll the rice into the outside of the cylinder 1. Through the processing of the rice, the ears of rice and straw are separated, avoiding slippage and improving the use effect.
