[Embodiment] First, as shown in the third and fourth figures, the present invention is provided with a movable seat (60) and a fixed seat (50). 70), a crushing stroke adjusting mechanism (80) and a crushing gap automatic adjusting mechanism (90); wherein the movable seat (60) is mounted on the machine table (50) by an eccentric shaft (61), and is mounted on the crushing surface The movable tooth plate (62); and the installation position of the eccentric shaft (61) is moved backward, and the crushing material is connected by the insert type feeding hopper (55) to prevent the broken material from directly impacting the bearing of the movable seat (60) and prolonging the bearing life; 1342234 The fixing base (70) is fixed to the machine table (50), and a fixed tooth plate (71) is mounted on the movable tooth plate (62) of the movable seat (6〇); the crushing stroke adjusting mechanism (80) will a crushing stroke adjusting seat (81) has a top pivot disposed on the machine table (50), and the crushing stroke is adjusted The rotation shaft (8Π) of the seat (81) is pivotally disposed on the machine table (50) by the eccentric sleeve (812), and the eccentric sleeve (812) has an eccentric distance between the inner diameter and the outer diameter, which can be adjusted by adjusting the eccentric sleeve ( 812) Angle, change the distance of the crushing stroke; further set a toggle plate (82) at both ends between the adjusting seat (81) and the bottom of the movable seat (6〇), and use a movable seat rod (83) equipped with a compression spring The toggle plate (82) is brought into close contact; therefore, since the fixed end of the toggle plate (82) is above the 'swing end, the inertial mass effect is mostly provided by the movable seat (60) body during the crushing process. Therefore, the inertial mass effect of the pulley and the flywheel is smaller than the conventional one, which can greatly reduce the weight of the pulley and the flywheel; and, due to the breaking stroke angle of the lower part of the movable seat (6〇), the movable tooth plate (62) is fixed to the fixed tooth plate. Αΐ) The movement of the lower side is repeated, so the service life of the fixed plate (71) is longer than that of the conventional one. In the case of high raw materials today, it can be described as a big breakthrough; further, the structure of the toggle (82) is in the process of crushing. 'Causing the movable plate (62) to be opposite the lower side of the fixed plate (71) The movement mode of the repetitive movement is better than the movement of the traditional structure movable tooth plate toward the side of the fixed slab. The crushing effect is better, and the productivity is also large. However, the movable seat lever (83) is combined with the A connecting rod (84) 'the end of the joint (84) is provided at the end of the breaking gap automatic adjustment mechanism (10) (94) 'the first end of the connecting rod (84) and the second connecting rod (85) The other end of the second end link (85) is coupled to the movable seat (10); and as shown in the fifth and sixth figures, the automatic breaking adjustment mechanism (9〇) will be a stop plate. The upper steel groove (8) and the pair of triangular model blocks -8 - 1342234 (92) are arranged in a positioning adjustment seat (93) fixed to the machine table (50), and the stop plate (94) is set at the stop Between the steel groove (91) of the plate and the middle section of the crushing stroke adjusting seat (81), and the adjusting rod (95) equipped with the compression spring, the stopping plate (94) is abutted tightly, and by the pairing control The position of the triangular wedge block (92) is used to change the position of the steel groove (91) on the stop plate, and then through the stop plate (94), the crush stroke adjustment seat 81), the toggle plate (82) and movable seat (60), is set active dental plate (62) and the fixed tooth plate (71) a crushing gap (W) between the persons. Therefore, the crushing gap adjustment process does not need to loosen the spring and the locking spring, and the spring must be loosened and the spring is locked after the adjustment is completed, which is convenient for adjustment. In addition, the triangular wedge block (92) is coupled to the movable end of a push rod (96), and the fixed end of the push rod (96) is pivotally mounted on the bracket (97) of the positioning adjuster (93). The rod (96) can be a hydraulic cylinder; however, if the excavator bucket teeth, the rock drill tungsten steel drill bit, etc., enter the crushing chamber, the crushing pressure is too large, exceeding the hydraulic circuit. When the safety valve is set, the triangular wedge block (92) will be quickly retracted, so that the crushing gap will be enlarged, and the non-crushed material will be quickly discharged out of the crushing chamber to prevent damage to the component and protect the machine body, which has an abnormally excessive load. efficacy. In addition, a lower buffer mechanism (100) is further disposed on the lower side of the blanking port, and a buffer seat (102) equipped with the impact plate (101) is pivoted on the lower side of the blanking port, and the buffering seat (102) A shock absorbing spring (103) is coupled to the opposite side of the impact plate (101) to absorb the impact force when the crushed object falls, thereby avoiding direct impact on the receiving member and preventing damage to the member. Also, please refer to the seventh and eighth figures, adjust the angle of the eccentric sleeve (812) set on the machine table (50), then adjust the angle of the toggle plate (82), and 1342234 is to adjust the breaking stroke distance. Therefore, in the case of crushed materials with low compressive strength, a larger crushing stroke distance can be selected to greatly increase the production capacity, and in the case of a crushed material having a higher compressive strength, a smaller crushing stroke distance can be selected. The load of each machine is reduced, and the damage of the components is avoided to improve the life of the machine. Therefore, the effect of adjusting the distance of the crushing stroke by eccentrically setting the angle is suitable for various crushed objects. Finally, please refer to the ninth and tenth figures. The eccentric shaft (61) of the movable seat (60) is mounted on the machine table (50), and the bearing seat (51) is fixed on one of the two sides. The bearing housing hole (53) of the side plate (52) and along the circumference of the bearing housing hole (53), and the lock inherent number of support rods (54) are evenly distributed between the side plates (52), having an average Supporting the bearing seat and improving the rigidity of the frame; however, the machine (50) is provided by the two side plates (52) for the movable seat (60), and the other side plates (not shown) The assembly structure is a design method of assembling the building blocks, which can be separately carried to the on-site assembly, and has the advantages of low transportation cost and convenience. Based on the configuration, the automatic breaking adjustment mechanism (90) of the present invention uses the thrust of the push rod (96) to match the pulling force of the movable seat rod (83) and the adjusting seat rod (95) to make the triangular wedge block (92). The lateral force generated by the sliding pushes the steel groove (91) and the stopper plate (94) on the stopper plate, and then the yaw of the crushing stroke adjusting seat (81) is pushed by the toggle plate (82). Seat (60), and then set the breaking gap (W) between the movable plate and the fixed plate; thereby, it is only necessary to move the position of the pair of triangular wedge blocks (92), and no other need for 1 to 2 minutes The action can set the breaking gap, which has the effect of simply and quickly setting the breaking gap. -10 - 1^42234 is the crushing stroke adjustment seat (8)): the stop plate (94) is a fixed point at the point of contact; thus, the reason: = η's flexibility' allows the crushing stroke adjustment seat (81) to When an abnormal load is applied, the deflection due to the deflection of the section below the fixed point cancels the abnormal load, so it has the effect of absorbing an abnormally large load. ,
