In order to better understand the technical scheme of the present application, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

The embodiment discloses a jaw breaking device of refractory material, see fig. 1, it includes jaw breaker 1, in order to solve the problem that the prior art locates the jaw breaker subaerial, consequently receive the underground space restriction and make the maintenance of equipment difficult, reduce maintenance efficiency, in this embodiment, locate subaerial with jaw breaker 1, and consider jaw breaker 1's ejection of compact dust problem, in this case, set up the feed well in the below of jaw breaker discharge gate, the piece is broken through jaw breaker back direct access feed well in, thereby avoid the adverse effect of dust that produces when breaking to the surrounding environment, and be equipped with below jaw breaker and be used for holding the collecting bin of powder, be used for transporting auger and/or the lifting machine of powder in the collecting bin to the next process, thereby realize transporting the conveying of powder after breaking.

In addition, after the jaw crusher 1 is disposed at the ground, since the feed inlet 11 of the crusher is disposed at the top of the apparatus and has a certain height, in order to facilitate the feeding of the material pieces, in this embodiment, a feed table 2 is disposed, the jaw crusher 1 is attached to the feed table 2, and in order to facilitate the material pieces to roll down from the feed table 2 to the feed inlet of the jaw crusher 1, the height of the feed table 2 is set to be not less than the height of the feed inlet 11 of the jaw crusher, in this embodiment, the feed table 2 is at the same height as the feed inlet 11 of the jaw crusher.

However, considering that the feeding table 2 has a certain width and the width of the feed inlet 11 of the jaw crusher is limited, in order to avoid the material blocks from rolling off the feeding table 2, a guiding groove plate 3 is arranged on the feeding table to realize limit guiding with the material blocks, so that each material block finally rolls off to the feed inlet 11 of the jaw crusher in a concentrated manner. Referring in particular to fig. 1, in this embodiment the guiding chute plate 3 is arranged symmetrically with respect to the centre line of the feed opening 11 of the jaw crusher.

The material blocks to be crushed are generally piled up in a piling area, the area is a certain distance away from the jaw breaking device, and the material blocks have a certain weight, so that a traveling crane is arranged for transporting the material blocks, and a hopper 4 is arranged at the position of the traveling crane lifting hook for improving the transportation efficiency, so that a plurality of material blocks can be received at one time, lifted to a feeding table 2 in a unified manner and then broken.

Considering that the hopper 4 can weigh several tons after loading the material blocks, in order to facilitate the dumping operation of the hopper 4 loaded with the material blocks, in this embodiment, the guide trough plate 3 includes a guide portion 31 and a reducing portion 32 welded to the guide portion 31, see fig. 1, the trough plates on both sides of the guide portion 31 are arranged in parallel, and the distance between the two trough plates is greater than the width of the hopper 4, so that the hopper 4 can fall into the area between the two trough plates, the dumping operation is performed, and the material blocks are prevented from rolling and dispersing from both sides, and are guided to the feed port of the jaw crusher 1 by the reducing portion 32 through the trough plates with gradually reduced distance between both sides, thereby realizing the concentration of the material blocks. In addition, in this embodiment, in order to enhance the stress intensity of the guiding groove plate 3, referring to fig. 1, a plurality of supporting members 33 are respectively arranged on the outer sides of the guiding groove plate 3 in an array manner, in this embodiment, i-steel is used as a supporting member, and abuts against the outer sides of the guiding groove plate 3, so as to avoid deformation or skew of the guiding groove plate 3 after being impacted or pressed by the material blocks in the groove.

In addition, since the guide trough plate 3 has a certain height, a certain unobstructed area exists at the top of the jaw crusher 1 at the end of the reducing portion 32, through which a portion of the material block falls to the surrounding ground under inertia. Therefore, in this embodiment, referring to fig. 1, the baffle 5 is disposed at the end of the guide slot plate reducing portion 32, specifically, opposite grooves are disposed at two opposite side walls of the reducing portion 32, and a thickness of the baffle is selected to be a certain width of the groove, so that the baffle 5 is limited by the groove, so that the baffle 5 can slide in the groove, the baffle is disposed when the jaw crusher 1 works, and when the feeding port 11 is overhauled, the baffle 5 is taken out from the groove, and an overhauling space is opened.

In addition, in the present embodiment, the feeding table between the guiding portions 31 of the guiding trough plate 3 is in a slope shape, and the height position near the feeding port 11 side of the jaw crusher is relatively low, so that the material block can be urged to roll towards the feeding port 11 under the action of gravity, and the manual participation is reduced.

In order to facilitate the dumping of the material blocks in the hopper 4, referring to fig. 1, a limit groove 6 is arranged at the end side of the guide part 31 of the guide groove plate 3, which is close to the reducing part 32, and limit rods 7 are respectively arranged at the bottoms of the two end sides of the dumping mouth of the hopper 4, which are perpendicular to the corresponding sides, the diameter of each limit rod 7 is matched with the width of each limit groove 6, and the limit rods have a certain length, so that the limit rods 7 can fall into the limit grooves 6 and extend out of the groove plate for a certain length. After the control row hangs down the discharging hopper and the limit rods 7 at the two end sides of the control hopper fall into the limit grooves 6, the control row is hung again to enable the rear part of the hopper to be lifted, so that the hopper 4 rotates around the limit rods 7, and dumping of the material blocks is achieved. In this embodiment, two rows of cranes are used for transporting the hopper, and the two rows of cranes are used for hoisting the front part and the rear part of the hopper respectively, and only the row crane corresponding to the rear part of the hopper is required to be controlled to lift during dumping operation. In other embodiments, a crane is used for lifting the hopper, the lifting points around the front and rear of the hopper are connected to the crane lifting hooks, when the crane is in dumping operation, after the limiting rods 7 at the two end sides of the hopper fall into the limiting grooves 6, the crane is lifted to continue to move forward towards the jaw crusher, and the stress of the lifting ropes at the rear of the hopper is gradually increased due to the limiting of the limiting grooves on the hopper, so that the rotation of the hopper around the limiting rods 7 is finally realized.

In other embodiments, in order to avoid the stop lever 7 slipping out of the stop slot 6 when the hopper 4 is dumping the material, the stop slot 6 is provided with an L-shape, which includes a vertical slot and a lateral slot, and the lateral slot is provided on one side close to the jaw crusher, so that the stop lever 6 can be clamped therein to avoid slipping out during dumping operation. In addition, in this example, in order to avoid deformation of the trough plate, a support is provided on the side of the limiting trough 6 close to the jaw crusher, in order to avoid that the limiting trough needs to bear a large load, thereby improving the stress intensity.

Furthermore, in the present embodiment, considering that it is difficult to achieve concentration of all the lumps to the jaw crusher feed port 11 by means of only the slope of the feed table, referring to fig. 1, the outer sides of the guide chute plates 3 of the feed table 2 are respectively provided with manual operation tables 8, thereby providing an operation platform so that an operator can push and sweep the remaining lumps to the jaw crusher feed port 11 by means of a tool on the top surface thereof.
