Abstract

The invention relates to a mower ball-throwing test device, which is characterized in that the test device comprises a test platform on which a cocoa mat is laid; a bracket is arranged below the test platform; a connecting block and an air cylinder are mounted on the bracket; a launching conduit is fixedly mounted between the connecting block and the test platform and is perpendicular to the test platform; a photoelectric sensor is arranged in the launching conduit; a transmitting tube and the launching conduit are coaxial; the upper end of the transmitting tube is slidably sleeved in the connecting block; the transmitting tube is connected to a piston rod of the air cylinder through a connecting plate; the lower end of the transmitting tube is connected to an air compressor air supply through an air hose; an electromagnetic valve is arranged in the air hose; a ball conveying tube is obliquely connected to the connecting block; and a steel ball is conveyed into the launching conduit by the ball conveying tube. The mower ball-throwing test device is simple and compact in structure, convenient to operate, and low in manufacturing cost, and meets the test requirements and testing specifications of EU standard.

Description

technical field [0001] The invention relates to a test device, in particular to a lawnmower ball throwing test equipment, which is used to test the safety of the lawnmower cover. Background technique [0002] When the lawn mower is working, it may encounter small movable hard objects (such as small stones) splashing into the lawn mower cover. Therefore, European standard EN60335-2-77 No. 21.101.1 has made strict safety regulations for the lawn mower cover. The test content includes: use the launching device to launch a steel ball with a diameter of φ6.35. The launching frequency and the launching height of the steel ball can be adjusted by adjusting the operating frequency of the device. The launching height of the steel ball is within 30-100 mm on the upper surface of the coconut mat It can be launched continuously, and the number of steel ball ejections can be recorded through the counter. Test requirements: 500 grains each time, when the count reaches the set value, it w...
