Description
Technical field
The invention belongs to agricultural mechanical field, particularly relate to a kind of straw pulverizer test bench.
Background technology
At present, the stalk crasher performance also imperfection used with matched with combine, ripe machine also prepattern; Be directed to Different Crop stalk, different machines is also in research and development advanced development; Be applicable to the different machines of same origin stalk, performance does not have systematic parameter according to comparing its difference, this is unfavorable for research and development and the innovation of machine.Test based on to different stalk crashers, by gathering the value of consult volume such as rotating speed, moment of torsion, in conjunction with its crushing effect, carry out the performance of com-parison and analysis machine, domestic also do not have special testing stand at present.
Summary of the invention
The object of the invention is the deficiency in order to make up prior art, providing a kind of straw pulverizer test bench, for making a service test and safety test to the various crackers with matched with combine.
The present invention is achieved through the following technical solutions:
A kind of straw pulverizer test bench, it is characterized in that: include cracker support stand, drive motors support stand, protective cover and feeding table, detachable installation cracker to be tested on described cracker support stand, and be provided with protective cover outside it, described protective cover front end is provided with feeding table, described drive motors support stand is provided with drive motors and torque sensor, described drive motors output shaft is connected with the right-hand member of torque sensor by yielding coupling, left end and the cell overload of described torque sensor protect the yielding coupling right-hand member of axle to be connected, the gimbal coupling left end of described cell overload protection axle is connected with cracker line shaft to be tested, described cell overload protection axle is arranged on drive motors support stand by bearing block.
Described cracker support stand is provided with for embedding the loaded and unloaded U-shaped table top installing cracker to be tested, described U-shaped table top is furnished with polylith for regulating the loaded and unloaded backing plate of table surface height, described U-shaped table top has the bar-shaped trough for regulating installation longitudinal separation.
Stalk to be transported to by conveyer belt on the cracker to be tested that is arranged on cracker brace table by described feeding table.
Described protective cover adopts transparent PC force-bearing plate material, and has feeding port.
Its principle is: be inlaid in by cracker in U-shaped table top, is arranged on fixed mount, regulates its position, after ensureing the gimbal coupling axiality of cracker line shaft and cell overload protection axle, is fixed by cracker, cover protective cover with bolt pair.Stalk is transported to the feeding mouth of cracker through protective cover equal and quantitative by conveyer belt by feeding table; cracker line shaft is connected with the gimbal coupling being arranged on torque sensor overload protection axle head; motor is operated after being powered by the outside frequency conversion equipment of testing stand; its output shaft drives torque-transmitter shaft to rotate by yielding coupling; torque sensor drives overload protection shaft to rotate, and overload protection shaft drives load operation by gimbal coupling.In work, load operation speed is adjustable.In each moment, torque sensor output voltage signal, collection signal is converted into the value of consult volume such as rotating speed, moment of torsion under corresponding state, thus can measure the cutting force of cracker.
Advantage of the present invention is:
(1), testing stand general structure is simple, and installation position is adjustable, can meet different cracker line shaft and coaxially be connected with testing stand drive assembly.
(2), moment of torsion passes to torque sensor by overload protection shaft by load, and cell overload can be prevented impaired.
(3), stalk can be transported to cracker feeding mouth to be tested by conveyer belt by feeding table equal and quantitative
(4), protective cover adopts transparent endurance material, both ensured intensity, is convenient to again observe monitoring.
