A rice thresher is a machine used for threshing rice, which can be operated on a simple level and can be installed anywhere in the field. There are several models, including those for different environments and conditions, which can be customized to suit the conditions in the field. Towing is another important function of this machine, as it can be attached to a pick-up or power tiller for easier transportation.
Threshing precision of rice thresher machine
A rice thresher is a specialized device used to separate grains in a plant. The schematic diagram shows the various parts of a threshing machine. They include a programmable logic controller, a photoelectric switch, a panicle conveyor, a threshing unit, a feeding plate, and a centrifugal fan. The rice threshing precision of a machine can be controlled by various mechanisms, including a camera that detects breakages. Another characteristic of a rice thresher is its ability to automatically evaluate yield-related traits.
This threshing unit is equipped with a cam vibration mechanism. The rotating cam is connected to a sieve plate. The sieve plate is designed with fish-scale-shaped holes, which help in screening grains. The vibrations are caused by the grain’s movement across the sieve plate. The tangential threshing cylinder also rotates at high speed. As a result, the rice grain and the straws attached to the sieve plate deviate from the normal path.
This study also looked into the tangential vibration of rice threshing cylinders. It was observed that the vibrations of tangential cylinders were more than the incentives frequency, which would not cause resonance phenomenon. However, the tangential threshing cylinder’s model vibrations were observed to be dynamic and real-time. Furthermore, the distribution of the threshing bars in the cylinder also influenced the vibrations of the tangential cylinder.
The efficiency of a rice thresher machine is influenced by several factors, including the drum speed and the feed rate. Higher drum speeds and rotational speed lead to high impact from the threshing teeth, which increases the amount of grains threshed in the same time. Additionally, the higher the rotational speed, the greater the efficiency and the higher the yield of a rice threshing machine.
The low breakage rice thresher machine is designed to process rice without breaking it. Its threshing process is fully automatic and runs in twenty seconds or less. This machine features a fish scale sieving plate, which is helpful for rice trait evaluation. The rice threshing unit is equipped with a photoelectric switch and a centrifugal fan. The rice thresher includes a programmable logic controller.
The cylinder is designed so that the stalks are fed along the axis, while the sloughed material is discharged from the other end. The machine is fitted with a concave screen and a grass guide to prevent the crop from entering the cylinder. The threshing teeth impact the ears of the crop and a cleaning device separates the grain and the straw.
In addition, the unit adopts a cam vibratory mechanism for screening grains. The cam rotates to drive the sieving plate. The holes are designed in the shape of fish scales. Moreover, the threshing unit incorporates a rotary revolving auger with six spike teeth. It is driven by a diesel engine or a frequency converter. The feeding device has an electric motor and a pulley to convey rice into the auger.
SRV farmers hire a service provider to bring a combined ASI to their fields. They normally pay tolls to use the machines. The convenience of the technology is directly related to its affordability.
The sensitivity of the thresher is measured by its efficiency in breaking the grains. Humans, after all, have a tendency to tire and become fatigued after working for long hours. The researchers tested a low breakage rice thresher machine by comparing samples of threshed paddy with a traditional rice thresher. The threshing capacity was identical between the two machines.
There is no need for a separate rice milling unit if you own a thresher machine. This machine is very simple to use and will leave no residue. The design incorporates a photoelectric switch to determine whether the rice has been properly threshed. It has a panicle conveyor, a centrifugal fan, and a fish scale sieving plate. Moreover, it uses a programmable logic controller to control the machine. This is a very useful feature that will reduce the work that farmers have to do.
The machine works with fish scale sieving unit and hierarchical multi-roller threshing. Its programmable controller technique enables it to complete whole threshing automatically. Its result has been favorable, with high precision and low breakage. Rice plants were also provided for testing. After all, no residue means no problems when using a rice thresher machine.
