Bale density is 50-80 kg/m3 for low pressure type, and 80 kg or more for high pressure type. 1) Oscillating Piston Type Pickup Baler This machine is also called Pendulum Type Pickup Baler. Suitable for loading on combine harvesters, direct bale loading or field placement. Bale length is 60-120 cm, 1-2 ropes, straw bales are close to square. The density of the bales made by this machine is low, vibration and noise are relatively large, so it is currently used less frequently. 2) Reciprocating Piston Type Pick-Up and Baling Machine This machine has a nearly 100-year history of development abroad and is a kind of baling machine with perfect structure and reliable performance. The 9KJ-147 pick-up baler is a small machine with a practical productivity of 5-7 tons/hour, an operating speed of 5 km/hour, and a power consumption of approximately 11.76 kilowatts. It is used with 14.7-18.4 kW tractors. The weight of the tied bales can be no more than 20 kg, either mechanically or manually. It is suitable for forage harvesting and can also be used with windrowers and combine harvesters. It is a kind of binding machine with strong adaptability. 3) Round balers There are five types of round balers on the domestic and foreign markets. Three of them are bundled from the outside to the inside. Bales are loose and tight and are easy to air dry. The other two are ground baling machines.

Visual Testing is the most commonly used test method in industry. Because most test methods require that the operator look at the surface of the part being inspected, visual inspection is inherent in most of the other test methods. As the name implies, VT involves the visual observation of the surface of a test object to evaluate the presence of surface discontinuities. VT inspections may be by Direct Viewing, using line-of sight vision, or may be enhanced with the use of optical instruments such as magnifying glasses, mirrors, boroscopes, charge-coupled devices (CCDs) and computer-assisted viewing systems (Remote Viewing). Corrosion, misalignment of parts, physical damage and cracks are just some of the discontinuities that may be detected by visual examinations.
