Abstract
The invention claims a mower ball-casting test equipment, which is characterized by comprising a test platform coated with a coir mat, wherein a bracket is arranged under the test platform, a connecting block and a cylinder are arranged on the bracket, an launching guide tube is fixed between the connecting block and the test platform and is vertical to the test platform, and a photoelectric sensor is arranged in the launching guide tube; a launching tube is coaxial with the launching guide tube, the upper end of the launching tube is slidingly sleeved in the connecting block, the launching tube is connected with a piston rod of a cylinder through a connecting plate, the lower end of the launching tube is connected with an air source of an air compressor through an air hose, and an electromagnetic valve is arranged in the air hose; and a ball delivering tube is connected with the connecting block obliquely, and a steel ball is input into the launching guide tube through a ball delivering tube. The mower ball-casting test equipment has the advantages of simple structure, convenient operation and low manufacturing cost, and satisfies the test requirements and detection specifications of national standards.
Description
Technical field
The utility model relates to a kind of test unit, especially relates to a kind of mower toss testing equipment, is used for the mower case is carried out security test.
Background technology
May encounter the hard thing of small movable (as handstone) during mower work splashes into the mower case, therefore, the standard EN 60335-2-77 21.101.1 of European Union has made strict security requirement to the mower case, content of the test comprises: with the steel ball of emitter emission φ 6.35 diameters, can regulate transmission frequency and steel ball firing altitude by the operating frequency of regulating device, the steel ball firing altitude is in 30～100 millimeters of cocoa mat upper surfaces, can launch continuously, by counter, record steel ball and launch number of times.Testing requirements: 500 each, count down to setting value and automatically quit work.At present, market does not also have to complete the test unit of this test event, in order to satisfy the requirement of European Union's standard, is necessary to develop a kind of test unit of Pass Test requirement.
The utility model content
The applicant is studied improvement for above-mentioned problem, and a kind of mower toss testing equipment is provided, and satisfies the testing requirements of European Union's standard and detects standard, and is simple and compact for structure, easy to operate, low cost of manufacture.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of mower toss testing equipment, comprise being covered with the cocoa mat test platform, support is arranged on below described test platform, and contiguous block and cylinder are rack-mount, launch tube is fixedly mounted between contiguous block and test platform and perpendicular to test platform, is provided with photoelectric sensor in launch tube; Power valve is coaxial with launch tube, and the upper end of power valve slides in contiguous block, and power valve connects the piston rod of cylinder by web joint, and the lower end of power valve connects the air compressor machine source of the gas by air hose, is provided with solenoid valve in air hose; The pipe of losing tilts to connect contiguous block, and steel ball is by the pipe input launch tube of losing.
Further:
Also be provided with pressure regulator valve in described air hose.
Technique effect of the present utility model is:
The disclosed a kind of mower toss testing equipment of the utility model, simple and compact for structure, easy to operate, low cost of manufacture satisfies the testing requirements of European Union's standard and detects standard.
Description of drawings
Fig. 1 is structural representation of the present utility model (original state).
Fig. 2 is structural representation of the present utility model (emission state).
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises and is covered with cocoa mat test platform 9, support 15 is arranged on test platform 9 belows, contiguous block 3 and cylinder 7 are arranged on support 15, launch tube 6 is fixedly mounted between contiguous block 3 and test platform 9, and launch tube 6 is provided with photoelectric sensor 8 perpendicular to test platform 9 in launch tube 6, and photoelectric sensor 8 is used for counting.Power valve 2 is coaxial with launch tube 6, the upper end of power valve 2 slides in contiguous block 3, power valve 2 can move up and down in contiguous block 3 and launch tube 6, power valve 2 connects the piston rod of cylinder 7 by web joint 1, the lower end of power valve 2 connects the air compressor machine source of the gas by air hose 11, be provided with solenoid valve 12 in air hose 11, the pipe 4 of losing tilts to connect contiguous block 3.In the present embodiment, also be provided with pressure regulator valve 13 in air hose 11.
During test, underproof mower 10 is fixed on test platform 9, the emission port of launch tube 6 be in mower 10 blade 14 below, the piston rod of cylinder 7 drops to Fig. 1 position, drive the below that power valve 2 moves to the pipe 4 of losing, make steel ball 5 (steel ball is sent into continually by feed mechanism) enter the port of power valve 2; The piston rod of cylinder 7 rises, and drives power valve 2 and moves to Fig. 2 position, and have a steel ball 5 to enter the port of power valve 2 this moment, and steel ball is just interior etc. to be launched at launch tube 6; Emission is by compressed air, pressurized air enters power valve 2 along air hose 11 steel ball is penetrated rapidly along launch tube 6 through pressure regulator valve 13, solenoid valve 12, firing altitude is regulated compressed-air actuated pressure by pressure regulator valve 13 and is controlled, and transmission frequency is controlled by solenoid valve 12; Be arranged on the photoelectric sensor 8 on launch tube 6 tops, steel ball namely gets a signal through out-of-date, by this signal can with solenoid valve 12 interlocks, control transmission frequency, control simultaneously emitting times.During test, blade 14 rotations of mower, the steel ball 5 of launching bumps against with the blade that is rotating 14, reaches testing requirements.
