To improve harvesting efficiency and prolong the combine harvester machine life,
Please always choose high-quality Combine Parts from www.cothda.com
1 Q: What caused the harvester blades to get clogged with straw during harvesting as the following situations?
Answer:
Check whether there is a large clearance between the combine parts, i.e the fixed harvester blades the moving harvester blades; If yes, narrow the distance between the fixed harvester blades and the moving harvester blades.
Check whether there is any damage to harvester blades and combine fingers; if yes, please change the qualified harvester blades and combine fingers.
Check whether the stubble is too slow and the harvester blades have clay on it. if yes, please raise the height of the harvesting crop stop harvesting.
Check whether the combine harvester cut into the wire, sticks, or any other hard sundries; If yes, please, remove the straw, wire, sticks, or any tough kinds of stuff.
Check whether the crops are too wet and caused the harvester belts to slip after wet. If yes, please stop harvesting if the ground is too wet and rotten. meanwhile, please adjust the tightness fo the combine harvester bels according to the manual instruction. if the combine harvester belt is too tight, it will affect the cropping speed, and if it is too loose, it will easily get a slip.
2 Question: What caused the grain accumulation and blockage in the combine header.
Answer:
Check whether the crop is too short, the cutter did not cut all the crop; If yes, please reduce the height of combine header and appropriately reduce harvest divider (LH RH 5T106-4814-0) to reduce advance speed, improve stubble height and reduce cutting width.
check whether the harvest divider is a little bit higher so the crops cannot be divided into harvester auger drum properly. If yes, please correct the bottom plate of the cutting table, or readjust the gap between the agur DRUM 5T106-5211-2 and the bottom plate; Clear blocked grain stalks
check whether the harvest divider revving too low to prick the crop;
Check whether the distance from the harvest reel to the bottom of the harvest platform is too small or too large. If yes, please adjust the harvester belt 5T101-5455-2for tightness.
4 What caused cut crops cut dumped forward?
Check whether the speed of harvester and reel pulley are mismatched. The harvester speed is a little bit quicker, and the reel REEL CENTER 5T106-5511-0 speeds slow. This makes the harvester blades touching the ground or not cut properly. If yes, please reduce harvester forward speed and increase the rotation speed of Harvester And pully 5T051 5355 to make it coordinated; Remove back soil or inspect the combine finger.
5 Question: What caused the excessive loss of harvesting
Answer:
The speed of the reel is too high and the number of hits is too high; The position of the reel combine reel pulley is forward, and the impact strength is high; Reel reel pull is on the high side, hitting the crop head. If the harvester working status like this, please reduce the speed and move the reel backward and lower the reel combine pull position.
6 Questions: What caused the harvester header drum blocked?
|
|
6Answer:
The reasons are as follows: the looseness of the combined harvester belts reduces the speed of the drive drum; the feeding amount was too large, the crop was moist and the stem was tough; the engine speed does not reach the rated speed.
Troubleshooting: The first choice is to shut down the engine and remove the clogged stem. Then, according to the fault reason, check the harvester belt tightness and drive drum speed to make the belt tightness and drum speed meet the requirements;
In order to reduce the feeding rate, reduce the forward speed or increase the stubble or reduce the cutting width, delay the harvesting or reduce the feeding amount appropriately;
Pull the throttle in place to allow the engine to reach the rated speed.

We can say that the threshing unit is the heart of your combine harvester machine. Its function is to separate the kernel from the cob via friction.
It can deliver you a processed grain rate of 68%. It does not matter the type of combine harvester you are using.
The rotation of your threshing drum makes it possible to achieve that grain rate. We design the threshing drum in a concave shape.
This will help in the rotation of your moving components in a fixed direction. We have rasp bars combined with your adapted concaves.
This will ensure that your grains have optimal separation. Replacing your threshing unit components knocks down your tailings.

Separating unit
We manufacture a separating unit which is unique and compatible with your combine harvester machine. The separating unit supplements your threshing unit.
Your crop requires additional processing. This is because of the threshing unit separation which does not exceed 68%on average.
You might find some models having a separating unit equipped with an impeller. Hence they are able to maintain a steady throughput of your grain.
You can also add a straw blockage flap to the separating unit. This will deliver you a smooth pull-through effect hence reducing the risk of blockages in your component.
Our combine harvesters are equipped with straw walker crankshafts. They oscillate in an alternate up-to-down motion.
This is to shake up your straw and collect your remaining grain that falls to the through. To improve the performance of our components, we have equipped them with one or several agitators.
These agitators tend to have forks to loosen and fluff your straw as it advances along with the straw walker. Separating system components is not easy.
You will experience some bulkiness and be subjected to a continual movement which will place them under mechanical stress. Keeping your material components in top condition will guarantee a consistent grain separation.
You can also be guaranteed throughput if your combine harvester is in top condition. At Cothda.com we offer you the best-separating unit.

Cleaning unit
The cleaning system is where your grains get cleaned. It is normally equipped with grain pans, sieves, and fans.
The function of the pan is to ensure your grains are fully distributed over the surface of your sieve. It is also the unit responsible for transporting your grains from the separator to the collector.
We have designed both upper and lower sieves to help you sort out your grains. They are available for purchase in different size openings.
We also design them to have a specific position on the machine where you will sort poorly threshed cobs.
The poorly threshed materials after sorting them you will have to send them to be thrashed again. This is done by the use of a tail elevator available on your way to the threshing unit.
We also have the grain elevator where your clean grain will be deposited.
We have also designed responsible movers for lifting your straw and bale residue. After lifting the residue, the fan is responsible for sending it to the lower parts of the machine.
Always be keen on these parts as they can easily be exposed to stretching when left under stress. This will later reduce their life span leading to poor production at the end.
You can always ensure the oiling and greasing of these parts are done before and after cleaning your grains. It not always easy to compare the losses accrued due to cleaning performance and the overall production
At Cothda.com we give you a listed catalog to select your cleaning unit which is compatible with your combine harvester. We always work hard to make sure you get reliable parts that boost your machine performance.
Ordering from Cothda.com gives you an opportunity to select from a million of listed combine harvester parts. This freedom will bring a lot of discipline throughout your project.

Grain and tailing collection unit
After successfully cleaning your grain from straw and bale residue, you need to lift it for storage. You can do this by using a grain auger that transports it to the elevator.
The un-threshed cob residue is sent to the tailing auger. This tailing auger transports them via a second elevator back to the threshing unit.
Our grain and tailing elevators are designed to have elevator chains with paddles mounted on sprockets. These combine parts ensure that your grain and tailing elevators function effectively and efficiently.
We recommend you place a heavy demand for these combine parts as they handle high volume materials. That is why you should conduct routine inspections to guarantee consistent grain and discharge rates.
The paddles in top condition will increase the amount of your material transported during each flow. To make sure you get reliable combine parts that boost your machine performance, we offer you a wide collection of combine harvester parts.

Chopping system
After threshing, you will be left with straw and chaff. You can windrow or chop the straw remaining in the separation system.
If you don’t want to store the straw, you can chop and spread it in your field. This will make stubble plowing easier for the next activity.
The straw is processed by an extra fine-cut chopping system. This system consists of moving and fixed knives adapted to different harvesting applications for your machine.
Fan airflow is used to extract the chaff from your cleaning system. Our chaff spreader is comprised of discs and paddles which distribute it evenly according to the required working width.
