Detailed ways

A vanadium-titanium ore jaw crusher, characterized in that: it includes a frame, a fixed jaw crushing plate, a movable jaw, and a connecting rod are arranged on the frame, a crushing cavity is formed between the fixed jaw crushing plate and the movable jaw, and the upper end of the movable jaw is There is a mandrel for connecting with the frame, the upper end of the connecting rod is provided with an eccentric shaft, and a pulley is provided on the eccentric shaft, and the lower end of the connecting rod is provided with a front thrust plate for connecting the connecting rod and the movable jaw. The lower end of the connecting rod is provided with a rear thrust plate for connecting the connecting rod and the frame, the movable jaw is provided with a crushing plate, and the working surfaces of the fixed jaw crushing plate and the crushing plate are provided with parallel and longitudinally extending bars The bar-shaped tooth includes a start segment, a middle segment and an end segment, the end segment is parallel to the start segment and staggered, and the middle segment is connected between the start segment and the end segment. the

The section of the bar tooth is trapezoidal. the

The two connecting ends of the crushing plate have the same shape, and the two connecting ends of the crushing plate have the same shape. the

Rib seats are provided on both sides of the lower end of the connecting rod, rib seats are provided at the lower end of the rear wall of the movable jaw, and rib seats are provided on the rear wall of the frame, and one end of the front thrust plate and the rear thrust plate are supported on the rib seats The other end of the front thrust plate is supported on the rib seat at the lower end of the rear wall of the movable jaw, and the other end of the rear thrust plate is supported on the rib seat at the rear wall of the frame. the

The crushing cavity is composed of a crushing plate on the fixed jaw fixed on the frame, a movable crushing plate on the movable jaw, and two side lining plates on the two side walls of the frame to form a huge upper and lower truncated cylinder. After the crushed material is fed into the crushing chamber, the movement of the movable jaw will periodically change the volume of the crushing chamber to complete the crushing and discharging of the material. the

The crusher is driven by a motor, which drives the pulley on the eccentric shaft through belt transmission, and then through the rotation of the crank, the movable jaw in the crusher is periodically moved closer to and separated from the crushing plate on the fixed jaw. In addition to meeting the conventional design criteria such as operation, lubrication, installation, and maintenance, the structure of the jaw crusher must also consider the special structural requirements brought about by its specific operation and structural characteristics. Since the crushing load is a periodic sudden load, it is necessary to consider the adjustment of the speed fluctuation during operation to make the movement stable and to make reasonable use of the power of the prime mover. During the crushing process, non-crushed materials may fall into the crushing cavity, so the overload protection of the machine must be considered. When it is required to change the particle size of the product, the adjustment device of the feed port should be considered. When the locking device of the rib and its supporting pad key, etc. The crushing cavity of the jaw crusher is composed of a fixed jaw crushing plate and a crushing plate. Both fixed and movable jaws have crushing plates made of manganese steel. The crushing plate is fixed on the fixed jaw and movable jaw with bolts and maple. In order to improve the crushing effect, the surfaces of the two crushing plates are provided with longitudinal corrugations, and the convex and concave are opposite to each other. In this way, in addition to the crushing effect on the ore, there is also a bending effect. There are also manganese steel liners on both sides of the crusher working space. Because the wear of the crushing plate is not uniform, especially the lower part near the discharge mine mouth is the most worn. Therefore, the crushing plate is often made upside down so that after the lower part is worn, it can be turned upside down and reused. The crushing plate of the large crusher is composed of many pieces, each of which can be replaced, so that the service life of the crushing plate can be extended. the

In order to make the crushing plate fit closely with the movable jaw and the fixed jaw, there must be a liner made of plastic material between them. The liner is made of zinc alloy or plastic large aluminum plate. Because the fit is not tight, it will cause a large local overload, damage the crushing plate, break the fastening bolts, and even cause the breakage of the movable jaw. the

The movable jaw is suspended from the mandrel, which is supported in slide bearings on the side walls of the machine frame. The mandrel of the movable jaw swings back and forth to the fixed jaw. the

The swing of the movable jaw is realized by the crank rocker mechanism. The crank double rocker mechanism consists of an eccentric shaft, a connecting rod, a front thrust plate and a thrust plate. The eccentric shaft is placed in the main bearing on the side wall of the frame, the connecting rod is installed on the eccentric part of the eccentric shaft, one end of the front and rear thrust plates is supported on the rib seat in the groove on both sides of the connecting rod head, and the front thrust plate The other end is supported on the rib seat at the lower end of the rear wall of the movable jaw, and the other end of the rear thrust plate is supported on the rib seat in the wedge iron on the rear wall of the frame. When the eccentric wheel obtains rotational motion from the motor through the V-belt pulley, it causes the connecting rod to move up and down. The up and down movement of the connecting rod drives the thrust plate to move. As the thrust plate constantly changes the angle of inclination, the mandrel of the movable jaw swings. The ore is broken when the connecting rod moves upwards. When the connecting rod is at the lowest position of the lower part, the inclination angle formed by the thrust plate and the horizontal line is 10??--12?? 

The rear thrust plate is not only a rod for transmitting force, but also an insurance part of the crusher. When the crusher falls into an object that cannot be broken but the machine exceeds the normal load, the rear thrust plate is broken immediately, and the crusher stops working, thereby avoiding damage to the entire machine.

When the connecting rod moves downward, in order to keep the movable jaw, the thrust plate and the connecting rod in constant contact with each other, a tensioning device consisting of two pull rods and two springs is used. The pull rod is hinged on the earring at the lower end of the movable jaw, and its other end is supported on the lower end of the frame rear wall with a spring. When the movable jaw swings forward, the pull rod uses the spring to balance the movable jaw and the inertial force generated by the thrust plate. the

The jaw crusher has a working stroke and an idling stroke, so the load on the motor is extremely unbalanced. In order to reduce the unbalanced load, flywheels and pulleys are installed at both ends of the eccentric shaft. The pulley also acts as a flywheel. During the idling stroke, the flywheel stores energy and releases the energy during the working stroke. the

Put a set of spacers with a certain size between the rear wall of the rack and the wedge iron. When the thickness of the gasket is changed, the width of the ore discharge port can be adjusted. the
