Description
Technical Field
The invention belongs to the technical field of cone crushers, and particularly relates to a split type static cone assembly of a cone crusher.
Background
In tunnel engineering, a large amount of hole slag is generated, and in order to prevent the hole slag from polluting the environment, the hole slag is processed into machine-made sand and used as a basic building material, which is a very common environmental protection means. The processing of the hole slag needs to be subjected to multi-stage crushing so that the granularity of the product meets the requirements of various industries, and the crushing process comprises jaw crushing, cone crushing, impact crushing and the like. Jaw crushers have high crushing efficiency as a tool for primary crushing of a parent material, but because the control of the particle size of a product is difficult to achieve a preferable effect all the time due to the limitation of an inherent structure, the crushing tool such as a cone crusher is required to perform subsequent processing to control the particle size of the product to be finer.
The cone crusher is used as a second process for crushing the base material, and has the advantages of high-efficiency crushing and granularity control. Referring to fig. 1, after entering a hopper, a base material falls into a crushing cavity formed by a dynamic cone assembly and a static cone assembly, wherein the static cone assembly is of a funnel-shaped structure with a downward opening and fixed on an upper frame of a cone crusher; the movable cone assembly 2 is a movable mechanism which is arranged on the lower frame body 3, driven by the main shaft and moves eccentrically along with the eccentric sleeve. The gap between the dynamic cone assembly and the static cone assembly can periodically change along the circumferential direction of the cylinder body when the cone moves eccentrically, namely, the parent metal at the gap between the dynamic cone assembly and the static cone assembly begins to break each time the gap between the dynamic cone assembly and the static cone assembly is reduced at a certain position. The crushed product flows out along the crushing cavity and the product channel.
The control of the product particle size of the cone crusher is mainly achieved by adjusting the crushing chamber discharge opening 41. On one hand, the currently adopted method is to adjust the upper rack through threads, but the adjustment precision is very low; on the other hand, the height of the movable cone assembly 2 can be adjusted through a hydraulic cylinder or the height of the upper frame can be directly adjusted, but the structure is generally only available on a multi-cylinder cone crusher, and the cost and the maintenance difficulty are high. It is difficult to combine cost and effect with the adjustment of the crushing chamber of the cone crusher by existing means.

The rolling mortar wall part of the original static cone assembly is made into a split type, the upper part of the rolling mortar wall part keeps the original structure, the lower part of the rolling mortar wall part is made into a movable skirt part which is a movable skirt part, and the angle of the rolling mortar wall part can be accurately regulated and controlled by a screw rod regulating assembly 14 between the upper frame 4 and the movable skirt part so as to regulate the size of a discharge hole 41 of the crushing cavity, and finally, the regulation and control of the particle size of a product are realized. In addition, the movable skirt part is taken as one side forming the crushing cavity, so that the skirt part can be replaced very conveniently, and the material inlet part with slower wear can be used for a long time, thereby saving the cost to a certain extent.
According to the above-described operation principle, some preferred embodiments or implementation structures are provided, and as shown in fig. 1, the screw adjusting assembly 14 includes a screw 141, a plurality of adjusting nuts 142, and a supporting member 143, the supporting member 143 is used for adjusting the abutment of the nuts, a hole for the screw 141 to pass through is provided in the supporting member 143, the screw 141 passes through the hole, and is locked in the supporting member 143 by the adjusting nuts 142. The support 143 is connected to the crushing chamber wall 42 in the upper frame 4 of the cone crusher, which is simple in construction and stable.
The upper part of the movable skirt 12 and the lower part of the assembly fixing part are provided with first pin shaft installation seats 15, pin shaft holes matched with each other are arranged in the two first pin shaft installation seats 15, and the matched pin shaft holes are connected through an inserted pin shaft assembly. The pin shaft assembly generally consists of a snap spring or a pin shaft, a second pin shaft mounting seat 16 is arranged on the lower surface of the movable skirt 12, the second pin shaft mounting seat 16 protrudes out of the surface of the movable skirt 12, pin shaft holes matched with each other are formed in the connecting rod 13 and the pin shaft mounting seat, and the matched pin shaft holes are connected through the pin shaft assembly. The pin shaft connection is convenient to detach.
The gap between adjacent movable skirts 12 is less than the desired product grain size. The relative position relation of the adjacent movable skirt parts during installation has a gap between the two movable skirt parts due to angle adjustment, and if the gap is too large, particles can flow out of the crushing cavity when the crushing is not yet complete, the compression ratio of the crushing cavity is influenced, and the control of the granularity of a final product is not facilitated. Therefore, the size of this gap should be noted when adjusting the movable skirt to be smaller than the set granularity.
As shown in fig. 3, the number of movable skirts 12 includes four.

formula III;
formula IV;
wherein α=h-l 1 ；One skilled in the art will recognize that a scale may be provided on one side of screw 141. The angle of the movable skirt can be changed by adjusting the size of i, and the scales are arranged on the side wall of the upper frame 4 near the screw 141, so that the movable skirt can be greatly conveniently adjusted.
This cone crusher with split type quiet awl assembly can adjust the size of broken chamber to a certain extent, and then makes the product granularity change in order to reach the production needs, and specific application method is as follows:
cleaning the crushing cavity of the cone crusher from above the feeding hopper to ensure that no uncrushed stone is inside and prevent the injury of the user;
preparing to separate the upper frame from the lower frame, wherein in the separation process, the non-direct operator should keep a safe distance;
loosening bolts on the screw adjusting assembly 14 and removing the static cone assembly;
the screw adjusting component 14 on the wall of the upper frame 4, namely the vertical position of the adjusting screw, is adjusted, and the distance to be adjusted by the screw is calculated according to the angle required to be installed by the movable skirt part and the fourth angle; then firstly loosening the two lower adjusting nuts, if the position of the screw rod needs to be increased, screwing the upper adjusting nut clockwise, otherwise, screwing the adjusting nut anticlockwise; the adjusting nut is screwed while the scale corresponding to the screw rod is observed until the top end of the screw rod is aligned with the scale; finally, two adjusting nuts below are screwed down, and the screw adjusting assembly 14 is arranged; note that the gap to be controlled in the adjustment process is smaller than the required product granularity;
if the movable skirt part needs to be replaced, hot oil at the temperature of about 110 ℃ is used for spraying on the hinge to heat and lubricate the hinge, and then a tool is used for knocking out the pin shaft; the hinge can be installed by using a pin shaft which is cooled to-95 ℃ in advance when the movable skirt part is installed; after the installation is completed, the room temperature is restored and the next operation is carried out;
installing a static cone assembly, screwing two screws on the movable skirt hinge frame, and finishing the installation of the static cone assembly; the upper frame 4 is installed, the machine is operated under low power, and finally the production line is put into operation.
