Jiaheng hydraulic cylinder plays a core role in "power transmission and precise execution" in ensiling machine equipment. From flexible profiling of the cutting table, reliable clamping of the feeding roller, precise control of the shredding gap, to flexible steering of the throwing drum, high-performance hydraulic cylinders are indispensable. Its reliability, durability, and load capacity are directly related to the efficiency, quality of operation, and overall attendance rate of the ensiling machine. Choosing hydraulic cylinder suppliers like Jiaheng, who have a good reputation and reliable products, is crucial for silage machine manufacturers to ensure equipment performance and provide users with satisfactory user experience.

As a well-known hydraulic cylinder manufacturer in China, Jiaheng's products have a wide and important application in silage equipment. The following are the key links in which they mainly play a role:

1. Cutting table lifting and profiling control:

Function: The cutting platform in front of the silage machine needs to be adjusted and shaped according to the height of the crop and the undulations of the ground (conforming to the contour of the ground) to ensure the best harvesting effect and avoid missing or gnawing on the soil.

Oil cylinder application: Large hydraulic cylinders (usually double acting cylinders) are responsible for providing strong thrust to lift heavy cutting platforms. On advanced models, multiple oil cylinders are combined with sensors to achieve automatic contour control, allowing the cutting table to accurately follow the terrain undulations. Jiaheng's oil cylinder needs to have good load bearing capacity and precise position control response.

2. Adjustment of feeding roller gap and pressure control:

Function: The feeding roller is responsible for uniformly and continuously conveying the cut crops to the shredding device. The gap and clamping pressure between the feeding rollers can be adjusted for different crop types, dryness and wetness levels, and feeding amounts to ensure smooth feeding, avoid blockage or excessive squeezing.

Oil cylinder application: Hydraulic oil cylinders are used to drive the clamping mechanism of the feeding rollers, adjust the gap between the rollers in real time, and apply appropriate clamping force. The stability and precise force/position control capability of Jiaheng oil cylinder are crucial for ensuring feeding quality.

3. Adjustment of the clearance between the fixed blades of the shredding drum:

Function: The gap between the shredding drum (equipped with a moving blade) and the fixed blade (bottom blade) directly affects the shredding length (theoretical length) and shredding quality (whether it is torn or excessively broken). This gap needs to be adjusted according to the crop type and the required shredding length.

Hydraulic cylinder application: Hydraulic cylinders are used to accurately move the fixed blade beam or adjust the mechanism, changing the gap between the moving blade and the fixed blade. This requires the oil cylinder to have high rigidity and positioning accuracy to ensure consistency and stability in gap adjustment. Jiaheng's heavy-duty precision oil cylinder is often used in this critical area.

4. Rotation and lifting of the throwing cylinder (blowing cylinder):

Function: The chopped silage feed is blown into the carriage of the accompanying transport vehicle (truck or trailer) through a throwing drum (usually a long tube that can rotate and pitch). The throwing drum needs to be flexibly adjusted in direction (left and right rotation) and elevation angle (high and low) to achieve uniform fabric distribution at different positions of the carriage.

Oil cylinder application: Two main hydraulic cylinders (sometimes swing cylinders or rotary cylinders) respectively control the horizontal rotation and vertical pitch motion of the throwing drum. These oil cylinders need to have a large stroke range, good stability, and reliability in order for the driver to operate them conveniently during travel. Jiaheng provides various specifications of engineering cylinders to meet this demand.

5. Other auxiliary functions:

Storage bin/discharge door opening and closing: Some silage machines may have temporary storage bins or require controlled discharge ports.

Functions related to the walking chassis, such as adjusting certain suspension systems (although not all silage machines have complex suspensions).

Engine hood/access door opening and closing: Large hydraulic support rods (essentially special oil cylinders) are used to support heavy engine hoods or access doors.

Advantages of using Jiaheng hydraulic cylinder in silage machine (needs to be combined with specific product models and user feedback)

1. Structural reliability and durability: Agricultural machinery operates in harsh conditions (dust, vibration, impact, temperature changes). Jiaheng oil cylinders are typically designed with sturdy structures, high-quality seals (dust rings, high-pressure seals), and surface treatments (such as hard chrome plating) to enhance wear resistance, corrosion resistance, and pollution resistance, extending their service life.

2. Strong load capacity: able to provide the large thrust or tension required for various actions of the silage machine.

3. Sealing performance: A good sealing system is the key to preventing leaks, ensuring the cleanliness of hydraulic systems, and long-term stable operation of oil cylinders, especially in dusty agricultural environments.

4. Rich product series: Jiaheng provides various cylinder diameters, strokes, and installation forms of oil cylinders, which can meet the spatial layout and load requirements of different parts of the ensiling machine.

5. Quality control: Domestic well-known brands usually have strict standards in material selection, processing technology, and testing.

6. Service and Support: A relatively complete sales and after-sales network facilitates equipment manufacturers (OEMs) and end users to obtain spare parts and technical support.
