Brief introduction of silage harvester

This silage harvester and recycling machine are mainly used to cut silage and then crush them into small pieces by rotating blades. These small pieces are lifted to upload to the container. This chaff harvester needs to match with a 60Hp tractor and its capacity can reach 0.25-0.48 ㎡/h.

The harvesting width is 1.3 m and we also have other types with 1.35 m,1.5 m,1.65 m.1.7 m.1.8 m, and 2 m cutting width. You can choose one according to your needs. Also, we can customize this type of straw harvester machine for you.

Application of corn straw silage harvester

Grain stalks such as corn, sorghum straw, cotton straw, banana stalk, and other grasses all can be the raw materials. The final product of the chaff harvester can be used to feed animals and add the nutrition of soil etc.

Working principle of straw silage harvester

1. Firstly operator connects the grass cutter machine with a tractor.
2. 32 rotating blades constantly cut the straw when it begins to work.
3. Straw goes into the crushing part.
4. Then the fan blows the small pieces into the lifter.
5. The lifter conveys the small pieces into the container.
6. Finally, the hydraulic device on the tractor powers the machine to unload the crushed straw.

How to install a silage harvester

1. The operator should first connect the straw harvester to a tractor and then adjust the horizontal and vertical levels of the tractor and the stubble height. The length of the tractor’s suspension rod on both sides should be horizontal.

2. Adjustment of the height of the chopper knife from the ground

(1) Adjust the position of the ground wheel to the hole on the side plate.

(2) Adjust the length of the pull rod according to the humidity of the soil, as shown in the picture below

Advantage of silage harvester

  1. The crushed silage can return to the field again, which can add to the nutrition of the soil.
  2. Silage harvesting machines can work at high speed and can effectively improve working efficiency.
  3. Due to the hydraulic device, crushed silage can be unloaded easily.
  4. The recycling rate is more than 80%.
  5. 32 blades can fully cut the straw.

The preoccupation of silage harvester

1. Check and tighten the fasteners of joints.

2. Remember to remove the clay to avoid whelming the working load of the machine.

3. Lacking oil towards the bearing gap may trigger excessive temperature, and the operator should add it in time.

4. Open the fan cover and check whether the screws on the blade hub are loose. If loose, tighten them in time.

5. Before using the silage harvester, first check whether the components are intact and whether the fasteners are loose or not, and add gear oil to the gearbox.

6. The oil height is higher than the gear teeth. Add lithium molybdenum disulfide grease to each lubrication part.

7. After the inspection is completed, the corn stalk silage harvester should idle for 5-10 minutes to confirm that the components are in good working condition.

8. There is no abnormal noise before using.

Operation introduction of silage harvester

  1. When working, the silage harvester should be adjusted to a height of 20-50 cm from the ground (the lifting position should not be too high so as not to cause damage due to the excessive angle of the universal joint). Then, the operator connects the power output shaft which should rotate for 1-2. minutes, hanging up the working gear and slowly releasing the clutch. At the same time, you shall gradually adjust the hydraulic lifting handle to a specific height that is as same as the required grass height
  2. During operation, the number of rows and the speed of the corn silage harvester should be determined according to the density of the straw planting and the horsepower of the tractor respectively to ensure normal operation.
  3. it is forbidden to hit the soil. If that happens, you should adjust the height of the upper rod.
  4. you should always pay attention to observe whether the straw running outlet is smooth. If there is no straw thrown at the outlet, you should stop immediately and check if the fan is blocked.
  5. When turning, the straw harvester should be lifted, and lowered after turning. Straw harvester should keep stable when lifting and landing, and it is forbidden to reverse during work.
  6. During the operation, you should remove the grass and other obstacles. The ground should be reserved for the 3-5 meter space for the machine.
  7. Stop the operation immediately if you hear abnormal noise during the operation, and continue the operation if everything is normal.
  8. Check the tightness of the belt at any time during the operation in the case of reducing the speed of the cutter shaft and affecting the quality of the crushing effect and the wear of the belt.

The maintenance of the straw harvester

It is important to check the machine regularly and maintain it in time if there is something wrong.

1. maintenance

1.1 Check and tighten the fasteners at the joints

1.2 Check the gearbox sealing condition. The static joint surface does not seep oil, and the moving joint surface does not drip oil. It is necessary to replace the seal and oil seal

1.3 Adding molybdenum disulfide lithium base grease to each lubrication point

1.4 Remove the clay promptly to avoid increasing the working load of the machine.

1.5 Check the temperature rise of each bearing. If the temperature rise is too high, it is caused by the excessive bearing gap or lacking oil. It should be adjusted or refueled in time.

1.6 Open the fan cover and check whether the screws on the blade hub are loose. If loose, tighten them in time.

2. Quarterly maintenance

2.1 Clean the gearbox and replace the gear oil

2.2 Thoroughly remove the dirt, weeds, and oil on the straw harvester

2.3 Remove the V-belt and store it separately

Successful cases of silage harvester machine

This year, our customers from Pakistan and Ecuador ordered 10 sets of straw cutter machines with great satisfaction. He asked us to know many details about it such as capacity, cutting width, tractor, recycling rate, etc. We aim to solve every problem our customer has provide the best service and always keep our original aspiration as a salesman.
Influenced by patience and professional skills, he introduced our hay straw harvester machine to his friends after receiving the machine.
