[0009] Preferably, the limit block forms a transmission structure through the transmission rod and the connecting member, and the connecting member forms a moving structure through the adjustment rod and the bottom plate.

[0010] Preferably, the second fixing plate and the jaw plate assembly adopt the same structural setting, and the jaw plate assembly, the second fixing plate and the third fixing plate are plug-connected by plugging rods, wherein the plug rods vertically penetrate the middle of the first fixing plate, the second fixing plate and the third fixing plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By setting the jaw plate assembly, the overall structure of the jaw plate assembly adopts the same setting as the subsequent second fixed plate and the third fixed plate. There are three groups of first fixed plates, second fixed plates and third fixed plates in sections.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0020] like Figure 1-4 As shown in the figure, a crusher jaw plate that is easy to assemble includes a base plate 1, which is characterized in that a slot 2 is provided on the outer side of the base plate 1, a jaw plate assembly 3 is connected to the inner side of the slot 2, an insert rod 4 passes through the inside of the jaw plate assembly 3, a limiting mechanism 5 is installed on the rear side of the base plate 1, a second fixed plate 6 is provided below the jaw plate assembly 3, and a third fixed plate 7 is provided below the second fixed plate 6.

[0022] The limiting grooves 304 are symmetrically arranged about the central axis of the first fixed plate 301, and the crushing teeth 302 are integrated with the first fixed plate 301 to ensure the stability of the overall processing and use, and the three groups of fixed plates can be flexibly disassembled and replaced.

[0023] The limiting mechanism 5 includes an adjusting rod 501 , the outer side of the adjusting rod 501 is threadedly connected to a connecting piece 502 , two sides of the connecting piece 502 are symmetrically mounted with rotating shafts 503 , the outer side of the rotating shaft 503 is rotatably connected to a transmission rod 504 , and the other end of the transmission rod 504 is rotatably connected to a limiting block 505 .

[0024] The limit block 505 forms a transmission structure through the transmission rod 504 and the connecting member 502, and the connecting member 502 forms a movable structure through the adjustment rod 501 and the base plate 1, which can flexibly control the transmission rods 504 on both sides to drive the limit block 505 to be pulled inward, and thereby the first fixed plate 301 is stably clamped and installed on the base plate 1 to ensure that the overall installation is tightened and fixed.

[0025] The second fixed plate 6 and the jaw plate assembly 3 adopt the same structural setting, and the jaw plate assembly 3, the second fixed plate 6 and the third fixed plate 7 are connected by means of an insert rod 4, wherein the insert rod 4 vertically penetrates the middle of the first fixed plate 301, the second fixed plate 6 and the third fixed plate 7, and the jaw plate is segmented into three groups, namely the first fixed plate 301, the second fixed plate 6 and the third fixed plate 7, which can be connected and aligned by means of the insert rod 4, and the three groups of jaw plates can be assembled and fixed by aligning the card slot 2 through the rear guide plate 303.

[0026] Working principle: First, the overall structure of the jaw plate assembly 3 is the same as the subsequent second fixed plate 6 and the third fixed plate 7. The crusher jaw plate is segmented and arranged in three groups, namely the first fixed plate 301, the second fixed plate 6 and the third fixed plate 7. The alignment and assembly can be completed by plugging the plug rod 4 in series, and the three groups of jaw plates are aligned with the bottom plate 1 through the alignment slot 2 through the rear guide plate 303. It is more conducive to grinding and crushing. If different parts of the fixed jaw plate are damaged, the plug rod 4 can be pulled out, and the fixed plate to be replaced can be separated from the corresponding limit mechanism 5, and disassembled outward in the vertical direction of the bottom plate 1 for single replacement, which saves time and effort and is conducive to timely replacement and use. While ensuring that the overall stable installation can be achieved, the fixed jaw plate as a whole can be flexibly disassembled and replaced, thereby improving the efficiency of crushing and grinding of processed products and saving manpower.

[0027] Next, after installing the jaw plate, the limit blocks 505 on both sides are aligned with the limit grooves 304 for plugging and engaging, and the adjusting rod 501 in the middle is controlled to rotate, so that it drives the outer connecting piece 502 to translate and adjust through thread transmission, and the transmission rods 504 on both sides can be flexibly controlled to drive the limit blocks 505 to pull inwards, so as to stably engage and install the first fixing plate 301 on the bottom plate 1, and the second fixing plate 6 and the third fixing plate 7 with the same structure as the first fixing plate 301 can be fixed in the same way to ensure that the whole is pressed and installed. Compared with the jaw plate fixed by bolt connection in the past, the damaged jaw plate on the inner side can be directly removed in sections through the installation of the limiting mechanism 5 as a whole, and no tools are required for bolt removal, and the disassembly and assembly can be completed by manual control, thereby ensuring timely replacement of the jaw plate damaged during the grinding and crushing process, and the disassembly and assembly is faster. After the single jaw plate is separated from the limiting mechanism 5, there is only a vertically guided sliding connection between the guide plate 303 on the rear side and the slot 2, and there is no clamping restriction in the vertical direction with the bottom plate 1. The single jaw plate can be directly taken out for disassembly without moving other jaw plates around, which is convenient and flexible.
