- With reference to
FIGS. 3 and4 , the jaw crusher of the invention comprises a movingbase 60, afixed base 70, a crushtravel adjusting mechanism 80 and an automatic crushgap adjusting mechanism 90, all installed to amachine 50. - The moving
base 60 is installed to themachine 50 through aneccentric shaft 61, and a movingdie 62 is installed on a crushing surface, and the installation position of theeccentric shaft 61 is shifted towards the rear, and aninserting feed bin 55 collects crushed substances to prevent the crushed substances from impacting a bearing of the movingbase 60 directly, so as to extend the life of the bearing. - The
fixed base 70 is fixed to themachine 50 and includes afixed die 71 corresponding to the movingdie 62 of themoving base 60. - The crush
travel adjusting mechanism 80 is provided for pivotally coupling the top of a crushtravel adjusting base 81 to themachine 50, and anaxle 811 of the crushtravel adjusting base 81 is pivotally coupled to themachine 50 through aneccentric sleeve 812, and internal and external diameters of theeccentric sleeve 812 have an eccentric distance, and a crush travel distance can be changed by adjusting the angle of theeccentric sleeve 812. Further, atoggle plate 82 is installed on both ends of a bottom between theadjusting base 81 and themoving base 60, and apull rod 83 of themoving base 60 installs a compression spring for tightly pressing thetoggle plate 82. Since the fixed end of thetoggle plate 82 is disposed at the bottom and the moving end of thetoggle plate 82 is disposed at the top, therefore most of the inertia effects is provided by themoving base 60 during the crushing process, and the inertia effect of a belt pulley and a flywheel is smaller than the conventional one, so as to reduce the weight of the belt pulley and the flywheel. Since the crushing travel distance and angle at the bottom of themoving base 60 are moved repeatedly from the movingdie 62 to the lower side of thefixed die 71, therefore the life of thefixed die 71 is generally longer than the traditional one. The present invention is a breakthrough, particularly at the time when the price of raw materials is high. In the crushing process of the structure of thetoggle plate 82, the movingdie 62 is moved repeatedly with respect to the lower side of thefixed die 71. Compared with the traditional structure of repeatedly moving the movingdie 62 towards the upper side of thefixed die 71, the crushing effect of the invention is better, and the production capacity is higher. However, apull rod 83 of themoving base 60 is connected to thefirst link rod 84, and an end of thefirst link rod 84 is pivotally coupled to astop plate 94 of the automatic crushgap adjusting mechanism 90, and another end of thefirst link rod 84 is coupled to an end of asecond rod 85, and another end of thesecond rod 85 is coupled to the movingbase 60. - With reference to
Figs. 5 and6 , the automatic crushgap adjusting mechanism 90 arranges and fixes asteel slot 91 of astop plate 94 and a pair of triangular wedge-shaped lumps 92 to aposition adjusting base 93 of themachine 50 and installs thestop plate 94 between thesteel slot 91 of thestop plate 94 and the middle section of the crushtravel adjusting base 81. Apull rod 95 of the adjusting base having a compression spring tightly presses thestop plate 94 to adjust the position of the pair of triangular wedge-shaped lumps 92 to change the position of thesteel slot 91 of thestop plate 94, such that the crush gap W between the movingdie 62 and thefixed die 71 can be set by thestop plate 94, the crushtravel adjusting base 81, thetoggle plate 82 and themoving base 60. Unlike the traditional structure that requires loosening the spring and securing the spring after the adjustment is made, the present invention provides a more convenient way of adjusting the crush gap without the need of loosening the spring and securing the spring. - In addition, the triangular wedge-
shaped lump 92 is connected to a moving end of a pushingrod 96, and a fixed end of the pushingrod 96 is pivotally connected to asupport stand 97 of theposition adjusting base 93, wherein the pushingrod 96 can be a hydraulic cylinder. However, if an unintended crushing object such as a shovel bucket or a tungsten carbide drill of a rock borer enters into a crushing chamber, the crushing pressure will become very large and exceed the safety setting of a hydraulic circuit, and the triangular wedge-shaped lump 92 will retreat quickly to increase the crush gap and allow the unintended crushing object to pass through the crushing chamber quickly, so as to achieve the effects of preventing a damage to components, protecting the machine, and eliminating an abnormal too-large load. - Further, a blanking
shock absorption mechanism 100 installed at a lower lateral side of a blanking opening includes ashock absorption base 102 with animpact plate 101 pivotally coupled to a lower lateral side of the blanking opening, and theshock absorption base 102 is connected to avibration absorption spring 103 in an opposition direction of theimpact plate 101 for absorbing an impact force when crushed substances drop to prevent a direct impact onto the receiving components or a damage to the components. - With reference to
Figs. 7 and 8 , the angle of installing theeccentric sleeve 812 to themachine 50 can be adjusted to change the angle of thetoggle plate 82 or the crush travel distance. For a crushing substance with a smaller compressive strength, a larger crush travel distance can be chosen to improve the production capacity. For a crushing substance with a higher compressive strength, a smaller crush travel distance can be chosen to lower the load of each component, avoiding damages to components, and enhancing the life of components. Obviously, the effect of adjusting the crush travel distance by an eccentrically set angle is applicable for all kinds of crushing substances. - With reference to
Figs. 9 and10 , the way of installing aneccentric shaft 61 of the movingbase 60 to themachine 50 is to fix thebearing housing 51 into a bearinghousing hole 53 of anintegral sideboard 52 on both sides, and along the periphery of the bearinghousing hole 53, and a plurality ofsupport rods 54 are secured uniformly between the twosideboards 52 for providing a uniform support to the bearing housing and improving the rigidity of an frame. However, themachine 50 is comprised of twosideboards 52 installed to the movingbase 60 and other sideboards (not shown in the figure) installed at other positions, and the design comes with a modular block installation, so that the components of themachine 50 can be transported separately to a site for its installation, and thus lowering the transportation cost and providing a convenient way of transporting themachine 50. - Based on the aforementioned structure, the automatic crush
gap adjusting mechanism 90 of the invention uses the pushing force of the pushingrod 96 to operate together with the pulling force of thepull rod 83 of the moving base and thepull rod 95 of the adjusting base, such that the lateral component force produced by sliding the triangular wedge-shaped lump 92 pushes thesteel slot 91 of thestop plate 94 and thestop plate 94, and the deflection of the crushtravel adjusting base 81 and the pushing of thetoggle plate 82 onto themoving base 60 can be used for setting the crush gap W between the moving die and the fixed die. With such arrangement, the pair of triangular wedge-shaped lumps 92 can be moved to set the crush gap in 1-2 minutes without requiring any other procedure. The invention provides a simple, easy and quick way of setting the crush gap. - With reference to
Figs. 4 and7 , the crushtravel adjusting base 81 is comprised of a transverse beam and a slab connected between two arc I-beams, and the position pressed by itscorresponding toggle plate 82 is a force exertion point, and the position pressed by thestop plate 94 and disposed between its pivotal shaft and force exertion point is a fixed point. The flexibility of the I-beam allows the crushtravel adjusting base 81 to produce a curvature at sections below the fixed point to offset any abnormal load and provide an effect of absorbing an abnormally too-large load. - Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
