What is Threshe Engines?
A thresher is an agricultural machine used to separate cereal seeds from stalks and husks by knocking the plant, making the seeds fall out. This mechanization significantly reduced the labor-intensive hand threshing done with flails before the 18th century. The first threshing machine was invented by Scottish engineer Andrew Meikle around 1786, marking an early example of agricultural mechanization. While separate harvesters and threshers have largely been replaced by combines, simple machines like foot-operated threshers remain important in low-capital farming environments, such as on small farms in developing and developed countries aiming for self-sufficiency. Some Amish sects also use horse-drawn reapers and older threshers as appropriate technology.
Wheat/Rice Thresher Overview
Components of a Wheat Thresher
A wheat thresher is comprised of several key components: a threshing drum, a concave surface, a drum shell, a cleaning system, and a feeding chute. These elements work together to ensure an efficient threshing process.
Axial Flow Threshing Process
The machine operates on an axial flow principle where the crop is fed into one end, moves lengthwise through the drum, and after thorough threshing, the straw is ejected from the opposite end. During this process, the crop makes three and a half rotations around the drum, ensuring all grains are effectively separated.
Drum Design and Application
Specifically designed with a nail-type threshing drum, this machine is also suitable for threshing rice crops, showcasing its versatility in handling different types of grain.
Overview of Corn Threshers
Types of Corn Threshers
There are two primary types of corn threshers: the nail-tooth type and the axial flow type. The nail-tooth thresher features a drum with five to six rows of pins or teeth, typically made of threaded mild steel bolts or similar materials. Notably, a thresher equipped with spikes often requires less energy compared to one with bolts, making it a more efficient choice. Threshing is achieved through a combination of impact and friction, while separation occurs by suctioning material from the concave surface. Cleaning takes place on vibrating screens, which are standard components of the machine.
Mechanical Design and Efficiency
The fan and drum in a corn thresher are mounted on the same shaft, resulting in a more streamlined structure compared to impact threshers. This design simplification contributes to the machine's overall efficiency. The drive for the vibrating screen is derived from the main shaft, utilizing cross belts to transmit power.
Application and Suitable Crops
Corn threshers are specifically designed for threshing corn, making them an essential tool for processing this particular crop. Their effectiveness lies in their ability to separate grains through a combination of mechanical actions that ensure thorough yet gentle handling of the corn.

Versatility and Crop Preservation
Multi-crop grain threshers offered versatility beyond just wheat and barley, extending their use to other grains such as oats, rye, and rice. Additionally, these machines minimized crop loss during harvest, ensuring maximum retention of yield.
Functions of Threshe Engines
Purpose and Process
A thresher, designed exclusively to separate grains such as wheat, oats, rye, and barley from their stems, leaves, and other lightweight materials like straw and chaff, employs a complex process. Bales of grain and straw are fed into the machine, where they are first disassembled by a set of rapidly rotating blades. These blades break the baling twine, tear apart the grain bundles, and detach the seed heads from the straw.
Separation and Cleaning
Following the initial separation, the straw and seed heads are beaten against a grooved board to dislodge the kernels. The straw is then separated on a specialized rack. The remaining material undergoes further cleaning through a series of shaking sieves, which progressively become finer to effectively sort the grains. Finally, in the 'cleaner' section, a stream of air blows away any leftover straw and chaff, ensuring the grain is thoroughly cleaned.
Grain and Straw Management
The cleaned grain is collected in a hopper and then piped into bags or other storage containers for future use. Simultaneously, the straw and chaff are ejected onto a pile by a more powerful fan, managing the by-products of the threshing process efficiently.
Parts of Threshe Engines
Threshing drum
The threshing drum is the main component of the rice threshing machine and is used to separate the rice from the rice straw. The drum is made of metal or plastic material and is equipped with threshing rubber. When the drum rotates, the threshing rubber rubs up the rice grains from the drum, causing the rice grains to separate and fall into the filter tube.
Filter tube
The filter tube is a component that filters dust and dirt attached to the rice. The tube is made of metal or plastic material and comes with various types of filters. The destemmed rice grains must pass through the filter tube to make the resulting rice grains cleaner and of better quality.
Conveyor belt
The conveyor belt is part of the rice threshing machine and is used to transport the rice that has been separated and cleaned from the stalks to the storage area. The conveyor belt is made of rubber or plastic material and is equipped with a drive.
Speed regulator
The function of the speed regulator is to adjust the rotation speed of the threshing drum and the conveyor belt. This speed regulator can be adjusted manually or automatically, depending on the type of rice thresher used.
Power plant
The function of the power unit is to drive the threshing drum and conveyor belt. Power can be generated by a diesel engine, gasoline engine, electric motor or other engine capable of driving the rice thresher.
Rack
Racks are usually made of strong and durable metal or iron. The frame can be used to support the structure of the entire machine.
Wheels and brake systems
Wheels and braking systems help the machine move through the rice fields. The wheels on a rice thresher can be 2 or 4 and made of solid rubber or plastic material. Braking systems on rice threshing machines are also essential to ensure that the machine can stop when needed.
Control Panel
The control panel is used to control and monitor the threshing process. Typically, control panels feature various buttons and indicators such as start/stop buttons, speed controls, and temperature indicators.
Maintenance Tips of Threshe Engines
