Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
In the embodiment of the jaw crusher of the present invention, as shown in fig. 1 to 2, the jaw crusher includes a body, a fixed jaw plate fixing plate 1 is fixedly disposed on the body, and a fixed jaw plate 2 is fixedly mounted on the fixed jaw plate fixing plate 1. Move the articulated installation on the organism of lower extreme position department of jaw fixed plate 4, and the eccentric wheel actuating mechanism and the fixed plate transmission of moving jaw 3 are connected, move jaw 3 and install on moving jaw fixed plate 4, under eccentric wheel actuating mechanism's drive, move jaw fixed plate 4 and take and move the jaw around the pin joint reciprocating motion of lower extreme, the distance between two jaws in the motion process becomes little periodically to grow, just can become the less material of granularity with the material crushing when filling the material between two jaws like this. Decide the vertical setting of jaw 2, move the slope setting of jaw, form big-end-up's broken cavity between the two, the great opening in upper end is the feed inlet, and the less opening of lower extreme is the discharge gate.
The crushing parts of the two jaw plates are of a tooth-shaped structure, the crushing teeth 31 of the tooth-shaped structure extend along the feeding direction, namely the up-down direction, as shown in fig. 2, the protruded wave crests of the tooth-shaped crushing parts of the fixed jaw plate 2 are opposite to the inward-recessed wave troughs of the tooth-shaped crushing parts of the movable jaw plate, and therefore materials can be clamped conveniently to be crushed. Distance measuring sensor 5 sets up the position department that is close to the discharge gate at deciding jaw plate fixed plate 1, distance measuring sensor 5's signal generation end sets up towards the trough department of deciding the jaw plate, signal channel runs through the front and back side of the trough position department of deciding the jaw plate, distance measuring sensor 5's signal generation end passes through signal channel and moves the crest position of jaw plate and be broken tooth promptly, distance measuring sensor's measuring signal propagates to broken tooth after passing through signal channel on, distance measuring sensor just can detect broken tooth to distance measuring sensor's distance like this. The movable jaw plate is also provided with a distance measuring sensor at the position close to the discharge hole, and the installation position of the distance measuring sensor and the signal channel on the movable jaw plate have the same structure as the fixed jaw plate, so that the repeated description is omitted. Still be equipped with the controller on the organism, the detection signal of distance measuring sensor's detector can be received to the controller, and when the extreme value of the testing result of detection signal exceeded the setting value, the controller can send warning signal, reminds the user to change the jaw. And the two distance measuring sensors are both laser sensors.
When the jaw crusher works, the movable jaw plate reciprocates under the driving of the eccentric wheel driving mechanism, so that the distance between the two jaw plates changes periodically, and the detection result of the distance measuring sensor is a wave curve. After the jaw takes place wearing and tearing in the use, the distance between the broken portion of two jaws will grow, detect the extreme value of the wave form curve of structure, maximum value and minimum will grow promptly, the change volume is the wearing and tearing volume of corresponding jaw promptly, just so knows the wearing and tearing volume of jaw according to range sensor's testing result, can in time monitor the wearing and tearing condition of jaw effectively, just can change the jaw after the wearing and tearing volume reaches the setting value, avoid continuing to use the jaw and harm organism 6. The distance measuring sensors corresponding to the two jaw plates are arranged at the middle of the discharge port, so that the width of the outlet can be monitored, and the width of the outlet can be conveniently adjusted in time according to a detection result. It should be noted that, when the distance measuring sensor is used for measuring, the crusher idles, and does not crush materials, so that the materials are prevented from interfering with detection signals.
In other embodiments of the invention, a distance measuring sensor can be arranged on the rear side of one jaw plate; the distance measuring sensor can also be arranged at the middle position of the jaw plate at the feed inlet and the discharge outlet, the distance measuring sensor is still arranged at the position of the discharge outlet, and the distance measuring sensors can also be arranged at other positions, so that a plurality of positions of the jaw plate can be monitored, and the phenomenon that a certain position is excessively abraded is avoided; the distance measuring sensors can also be directly arranged on the two jaw plates, so that the distance measuring sensors need to be detached when the jaw plates are replaced; the distance measuring sensor can also adopt an electromagnetic sensor, an infrared sensor or other types of distance measuring sensors.
