Description

Technical Field

[0001] The present application relates to the field of crushers, and in particular to a cavity separation connecting plate for a crusher. Background Art

[0002] The crusher uses an electric motor as a power source to drive the crushing roller to rotate, so that the crushing knives on the crushing roller move relative to each other to crush materials. When the crusher is actually used, the interior of the crusher is usually divided into multiple crushing cavities, so that the materials can be more evenly dispersed into each crushing cavity after entering the crusher, thereby improving the crushing effect and efficiency.

[0003] When separating the crushing cavities, cavity separation partitions are required. Multiple cavity separation partitions are sleeved outside the main shaft and arranged at intervals. The top of the cavity separation partition is connected to the top of the crusher housing, and the bottom is connected to the top of the crusher bottom plate, so as to ensure that the cavity separation partition is in a fixed state.

[0004] For the convenience of disassembly and assembly and to improve the structural strength, the cavity separation partition generally consists of two crescent-shaped plate bodies. The two plate bodies of the cavity separation partitions on both sides can be connected to the housing by bolts, while the two plate bodies of the cavity separation partition in the middle only have two connection points, the connection effect is poor, and it is easy to be displaced or even bent during use. Utility Model Content

[0005] In order to improve the problem that the two plate bodies of the existing cavity separation partition are prone to deformation due to poor connection strength, the present application provides a cavity separation connecting plate for a crusher.

[0006] The present application provides a cavity separation connecting plate for a crusher, adopting the following technical solutions:

[0007] A cavity separation connecting plate for a crusher includes two side plates and an inner plate. The top of the side plate and the top of the inner plate are both connected to the inner top of the housing, and the bottom of the side plate and the bottom of the inner plate are both connected to the top of the bottom plate; the inner plate includes a first connecting plate and a second connecting plate, both the first connecting plate and the second connecting plate are crescent-shaped, and the end of the first connecting plate and the end of the second connecting plate are detachably connected through a positioning mechanism.

[0008] By adopting the above technical solutions, the connection between the top of the side plate and the housing, the connection between the bottom of the side plate and the bottom plate, the connection between the top of the inner plate and the housing, and the connection between the bottom of the inner plate and the bottom plate are all preliminary connections, realizing the preliminary fixation of the side plate and the inner plate. Under the positioning and connection of the positioning mechanism, the first connecting plate and the second connecting plate can be reliably connected to each other, and the detachable connection of the inner plate between the housing and the bottom plate is realized, thereby preventing the first connecting plate and the second connecting plate from deforming and reducing the stability of the cavity separation effect.

[0009] Optionally, the positioning mechanism includes a first positioning plate and a second positioning plate.

Then connect the top of the first connecting plate to the housing and the bottom of the second connecting plate to the bottom plate. Then complete the connection between the first positioning plate and the second positioning plate through countersunk head screws, so as to realize the reliable connection between the ends of the first connecting plate and the second connecting plate, and improve the connection strength of the inner plate between the housing and the bottom plate.

[0011] Optionally, the first positioning plate is provided with a first counterbore and a first threaded hole, and the second positioning plate is provided with a second counterbore and a second threaded hole. The first counterbore and the second threaded hole are coaxially arranged, and the second counterbore and the first threaded hole are coaxially arranged; one countersunk head screw is inserted into the first counterbore and is threadedly connected with the second threaded hole, and the other countersunk head screw is inserted into the second counterbore and is threadedly connected with the first threaded hole.

[0012] By adopting the above technical solution, the first positioning plate and the second positioning plate can be locked by two countersunk head screws, and the locking directions of the two countersunk head screws are opposite.

[0017] Optionally, a pair of first positioning grooves are provided on the inner wall of the first notch, a pair of second positioning grooves are provided on the inner wall of the second notch, a pair of first positioning protrusions are provided on the side wall of the first positioning plate, and a pair of second positioning protrusions are provided on the side wall of the second positioning plate; the first positioning protrusions are adaptively inserted into the first positioning grooves, and the second positioning protrusions are adaptively inserted into the second positioning grooves; the side of the first positioning plate opposite to the first positioning protrusion fits the notch of the second positioning groove, and the side of the second positioning plate opposite to the second positioning protrusion fits the notch of the first positioning groove.

[0018] By adopting the above technical solution, the first positioning groove cooperates with the first positioning protrusion, and the second positioning groove cooperates with the second positioning protrusion. In this way, the docking accuracy between the first positioning plate and the first connecting plate and between the second positioning plate and the second connecting plate can be improved, thereby improving the welding effect.

[0019] Optionally, a first welding groove is provided at the connection between the first positioning protrusion and the first connecting plate, and a second welding groove is provided at the connection between the second positioning protrusion and the second connecting plate.

[0031] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0032] Figure 1 is a reference drawing of the assembled state of the present application. Refer to Figure 1, A cavity-separating connecting plate for a crusher, comprising two side plates 1 and an inner plate 2. There is a housing 3 and a bottom plate 4 on the crusher. The two side plates 1 and the inner plate 2 are arranged between the housing 3 and the bottom plate 4, and the inner plate 2 is arranged between the two side plates 1. The top of the inner plate 2 and the top of the side plates 1 are both connected to the inner top of the housing 3, and the bottom of the inner plate 2 and the bottom of the side plates 1 are both connected to the top of the bottom plate 4. The connection between the side walls 1, the inner plate 2 and the housing 3 and the bottom plate 4 can play a role in initially fixing the inner plate 2 and the side plates 1.

[0033] See Figure 1 , The side plate 1 includes an upper connecting plate 11 and a lower connecting plate 12, and both the upper connecting plate 11 and the lower connecting plate 12 are crescent-shaped. The top of the upper connecting plate 11 is connected to the housing 3, and the bottom of the lower connecting plate 12 is connected to the bottom plate 4. Moreover, the upper connecting plate 11 and the lower connecting plate 12 can also be connected and fixed to the side wall of the housing 3 through bolts 13, thereby effectively improving the connection strength of the side plate 1 and realizing the complete fixation of the side plate 1. Under the locking action of the bolts 13, the upper connecting plate 11 and the lower connecting plate 12 can be reliably fixed. Moreover, after the upper connecting plate 11 and the lower connecting plate 12 are enclosed, they are annular, which is convenient for the main shaft of the crusher to pass through.

[0034] Figure 2 is a schematic perspective view of the inner plate. See Figure 2 and in combination with Figure 1 , The inner plate 2 includes a first connecting plate 21 and a second connecting plate 22, and both the first connecting plate 21 and the second connecting plate 22 are also crescent-shaped. The top of the first connecting plate 21 is connected to the housing 3, and the bottom of the second connecting plate 22 is connected to the bottom plate 4. In this way, the initial fixation of the inner plate 2 is realized, and after the initial fixation, the first connecting plate 21 and the second connecting plate 22 also enclose an annular shape that is convenient for the main shaft of the crusher to pass through.

[0035] Figure 3 is an exploded state reference view of the inner plate. See Figure 3 , Both ends of the first connecting plate 21 are provided with first notches 211, and both ends of the second connecting plate 22 are provided with second notches 221. One end of the first connecting plate 21 is butted against one end of the second connecting plate 22, and the corresponding first notch 211 and second notch 221 are in a communicating state. The other end of the second connecting plate 22 is butted against the other end of the second connecting plate 22, and the corresponding first notch 211 and second notch 221 are in a communicating state. A positioning mechanism 5 is arranged in the first notch 211 and the second notch 221. Through the positioning mechanism 5, the reliable connection between the end of the first connecting plate 21 and the end of the second connecting plate 22 can be realized.

[0036] See Figure 1 and Figure 3, the positioning mechanism 5 includes a first positioning plate 51 and a second positioning plate 52. A pair of first positioning grooves 212 are provided on the inner wall of the first notch 211, and a pair of second positioning grooves 222 are provided on the inner wall of the second notch 221. A pair of first positioning protrusions 513 are provided on the side wall of the first positioning plate 51, and a pair of second positioning protrusions 523 are provided on the side wall of the second positioning plate 52. The first positioning protrusions 513 are adaptively arranged in the first positioning grooves 212, and the second positioning protrusions 523 are adaptively arranged in the second positioning grooves 222, realizing the positioning of the first positioning protrusions 513 in the first notch 211 and the positioning of the second positioning protrusions 523 in the second notch 221. When the first positioning protrusions 513 and the second positioning protrusions 523 are installed, the side of the first positioning plate 51 relative to the side where the first positioning protrusions 513 are provided fits with the notch of the second positioning groove 222, and the side of the second positioning plate 52 relative to the side where the second positioning protrusions 523 are provided fits with the notch of the first positioning groove 212. In this way, by welding the first positioning plate 51 with the notch of the second positioning groove 222, the first positioning protrusions 513 can be quickly welded in the first positioning grooves 212, thereby realizing the connection between the first positioning plate 51 and the first connecting plate 21. At the same time, the second positioning protrusions 523 can be quickly welded in the second positioning grooves 222, thereby realizing the connection between the second positioning plate 52 and the second connecting plate 22.

[0037] The first positioning plate 51 is provided with a first counterbore 511 and a first threaded hole 512, and the second positioning plate 52 is provided with a second counterbore 521 and a second threaded hole 522. When the first connecting plate 21 is connected to the housing 3 and the second connecting plate 22 is connected to the bottom plate 4, the first counterbore 511 and the second threaded hole 522 are in a coaxial state, and the second counterbore 521 and the first threaded hole 512 are in a coaxial state. At this time, a countersunk screw 53 is screwed into the first counterbore 511, and the countersunk screw 53 is threadedly connected to the second threaded hole 522. Another countersunk screw 53 is screwed into the second counterbore 521, and the countersunk screw 53 is threadedly connected to the first threaded hole 512. In this way, the two-way locking effect on the first positioning plate 51 and the second positioning plate 52 is achieved. Since the first positioning plate 51 is connected to the first connecting plate 21 and extends into the second notch 221 of the second connecting plate 22, and the second positioning plate 52 is connected to the second connecting plate 22 and extends into the first notch 211 of the first connecting plate 21, after the first positioning plate 51 and the second positioning plate 52 are locked by the two countersunk screws 53, the first connecting plate 21 and the second connecting plate 22 can be reliably connected, thereby improving the overall strength of the inner plate 2 and effectively preventing the deformation of the first connecting plate 21 and the second connecting plate 22 caused by the first connecting plate 21 being only connected to the housing 3 and the second connecting plate 22 being only connected to the bottom plate 4, which in turn affects the cavity separation effect of the first connecting plate 21 and the second connecting plate 22 on the crusher. At the same time, through the setting of the positioning mechanism 5, the disassembly and assembly efficiency of the first connecting plate 21 and the second connecting plate 22 is effectively improved.

[0038] Figure 4 It is a cross-sectional view of the internal structure of the positioning mechanism and the inner plate. See Figure 4 and in combination with Figure 3 , the length of the first counterbore 511 is equal to the length of the second counterbore 521, the length of the first threaded hole 512 is equal to the length of the second threaded hole 522, and the sum of the lengths of the first counterbore 511 and the first threaded hole 512 is greater than or equal to the length of the countersunk screw 53. In this way, it is ensured that one countersunk screw 53 can be completely located inside the first counterbore 511 and the second threaded hole 522, and the other countersunk screw 53 can be completely located inside the second counterbore 521 and the first threaded hole 512, thereby effectively improving the flatness of the overall inner plate 2. Further, the sum of the thicknesses of the first positioning plate 51 and the second positioning plate 52 is not greater than the thickness of the first connecting plate 21 or the second connecting plate 22, ensuring that after the first positioning plate 51 and the second positioning plate 52 complete the connection function of the first connecting plate 21 and the second connecting plate 22, the sides of the first positioning plate 51 and the second positioning plate 52 will not protrude outside the first notch 211 or the second notch 221, further improving the flatness of the inner plate 2.

[0039] See Figure 2 and Figure 4, a first welding groove 213 is provided at the connection between the first positioning protrusion 513 and the first connecting plate 21, and a second welding groove 223 is provided at the connection between the second positioning protrusion 523 and the second connecting plate 22. When welding the first positioning block and the first connecting plate 21, stitch welding can be performed in the first welding groove 213. When welding the second positioning block and the second connecting plate 22, stitch welding can be performed in the second welding groove 223. In this way, the solder is concentrated in the first welding groove 213 and the second welding groove 223. While improving the welding effect by increasing the welding area, the flatness of the inner plate 2 after welding is further improved, and the service life of the inner plate 2 is increased.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
