The picture below shows a ram type of baler - NSC Agricultural Technology - Question 5 - 2021 - Paper 1

1. Must be robust and securely mounted to protect against debris.
2. Easy to remove and replace for maintenance and inspection.
3. Should have warning signs to alert users about potential hazards.

1. Safety guards covering moving parts to prevent access.
2. Emergency stop buttons that can be activated quickly in case of malfunction.
3. Slip clutch that disengages when excessive force is applied.
4. Shear bolts that break to protect the machine from damage during overload.

1. Ensure that all operators are trained and familiar with the machine's operation.
2. Regularly inspect the machine for any potential mechanical issues before use.
3. Always keep clear of moving parts and maintain a safe working distance.
4. Engage safety locks or labels before conducting maintenance or repairs.

Double-helical gear.

Cannot be used in gearboxes of cars because it cannot be meshed from the side, limiting its application.

1. Sturdy construction to withstand continuous use.
2. Availability of spare parts for repairs and maintenance.
3. Rotor housing should fit tightly to avoid leaks.
4. Ensure versatility in the feed aperture to handle different materials.

1. Ensures even distribution of materials for consistent performance.
2. Reduces the risk of mechanical damage from vibrations.
3. Facilitates easier maintenance access and operation.

1. Check that the anchor bolts are secure to prevent movement during operation.
2. Ensure proper alignment of the driving shaft for efficient power transfer.
3. Verify that the drive shaft guard is in place and undamaged for safety.

1. Enhances stability and reduces the risk of tipping over during transport.
2. Allows for greater weight distribution across the tractor’s rear tires.

1. Top link for depth adjustment.
2. Two lifting arms to raise and lower the implement.
3. Stabilizing chains or arms to maintain implement alignment.

The automatic depth control mechanism utilizes a sensitivity element that monitors the depth of the plough in response to varying soil conditions. When the plough penetrates too deeply in soft soil, or if it risks tilting up in hard soil, the mechanism automatically adjusts the plough's position, ensuring optimal operational depth for effective soil tillage.

It is essential to install bearings to minimize friction and wear of moving parts, which prolongs the lifespan of the pump and ensures smooth operation.

One important task is to apply the appropriate lubricant regularly to ensure that the bearings operate smoothly and efficiently.

1. Sliding gearbox.
2. Constant mesh gearbox.
3. Synchronized gearbox.
