[0033] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0034] This embodiment provides a split wear-resistant pressure wheel structure, please refer to Figure 1-8 As shown, it includes a bearing part 100, a wear-resistant part 200 and a bolt 300; the axial middle part of the bearing part 100 protrudes outward to form a mounting part 110, the outer edge of the maximum outer diameter of the mounting part 110 is located on a concentric virtual circle 500, and the outer wall of the mounting part 110 is concave at the virtual circle 500 to form a plurality of circumferentially arranged inner recesses 111; the wear-resistant part 200 adopts an integral or multiple split structures 210 and is arranged around the outer peripheral wall of the mounting part 110, the inner edge of the maximum inner diameter of the wear-resistant part 200 is located on the virtual circle 500, and the inner wall of the wear-resistant part 200 protrudes inward from the virtual circle 500 to form a plurality of circumferentially arranged inner protrusions 211; the bolt 300 is embedded in the peripheral wall of the wear-resistant part 200 and connected to the mounting part 110; wherein, the inner recess 111 and the inner protrusion 211 are limited and embedded by a concave-convex structure.

[0035] Specifically, the mounting portion 110 protrudes from the axial middle portion of the bearing member 100, and at the same time, the wear-resistant member 200 is arranged around the outer peripheral wall of the mounting portion 110, which is conducive to concentrated and strong compression of the biomass raw materials; and the inner concave portion 111 of the mounting portion 110 and the inner convex portion 211 of the wear-resistant member 200 can be stably embedded and limited by a concave-convex structure, thereby increasing the structural strength. At the same time, the wear-resistant member 200 adopts an inner convex structure, which increases the thickness of the mold in the pressure direction, thereby improving the impact resistance and wear resistance of the pressure wheel; wherein, when the wear-resistant member 200 adopts an integrated structure, the two concave and convex parts can be embedded by the embedding concave portion 112 and the embedding convex portion 212, and can also be embedded by the inner groove 113 and the outer boss 213.

[0036] In this embodiment, when the wear-resistant component 200 adopts an integrated structure, the bolt 300 is installed on the inner convex portion 211 and the inner concave portion 111 .

[0037] Specifically, when the wear-resistant part 200 adopts an integrated structure, it is convenient to install the entire part in place at one time, and on the basis of the embedded limiting structure, a bolt 300 is installed at each installation location to achieve good fixation.

[0038] In this embodiment, a limiting rod 400 is further included. The limiting rod 400 is disposed between the wear-resistant part 200 and the bolt 300 .

[0039] Specifically, the limiting rod 400 is used to limit the rotation of the bolt 300 installed in place, so as to keep the wear-resistant part 200 tightly installed on the installation portion 110.

[0040] In this embodiment, the limiting rod 400 is axially disposed through the side wall of the wear-resistant component 200 located on the side of the bolt 300 , and is disposed through the head of the bolt 300 .

[0041] Specifically, since the bolt 300 is embedded in the wear-resistant part 200, the bolt 300 is mostly a hexagon socket bolt 300, and the limiting rod 400 is passed through the head of the bolt 300. Compared with setting a limiting hole on the screw, this structure with a hole on the head is easy to process and does not affect the strength of the screw. At the same time, it is also easy to observe the position of the hole, which is conducive to the installation of the limiting rod 400.

[0042] In this embodiment, when the wear-resistant component 200 adopts a plurality of split structures 210 , the mounting surfaces of the inner concave portion 111 and the inner convex portion 211 include planes, and the planes are located on a virtual regular polygon.

[0043] Specifically, Figure 7 The virtual regular polygon shown is a regular decagon; the concave and convex mounting surface adopts a planar structure, so that the concentrated force-bearing part in the middle of the split structure 210 is radially thicker, which is convenient for improving impact resistance and wear resistance. At the same time, it is convenient to further process other structures based on the planar structure, such as concave and convex embedded structures.

[0044] In this embodiment, an embedding recess 112 is provided on the mounting surface of the inner recess 111 , and an embedding protrusion 212 is provided on the mounting surface of the inner protrusion 211 . The embedding recess 112 and the embedding protrusion 212 are adapted to be embedded in each other.

[0045] Specifically, the concave-convex embedded structure facilitates positioning and installation, and also improves structural strength, impact resistance and wear resistance.

[0046] In this embodiment, the embedding recess 112 and the embedding protrusion 212 are respectively disposed in the middle of the corresponding mounting surface.

[0047] Specifically, the embedded recess 112 and the embedded protrusion 212 are respectively arranged in the middle of the corresponding installation surface, which can stably support the middle part where the force is concentrated, while improving the limiting strength. In addition, it also provides a structural basis for setting bolts 300 on both sides.

[0048] In this embodiment, the bolts 300 are disposed on both sides of the embedding recess 112 and the embedding protrusion 212 .

[0049] Specifically, the bolts 300 are disposed on both sides of the embedding recess 112 and the embedding protrusion 212 , and can securely install and position the split structure 210 .

[0050] In this embodiment, the mounting surface of the inner recess 111 is provided with an inner groove 113, and the mounting surface of the inner convex portion 210 is provided with an outer boss 213. The inner groove 113 and the outer boss 213 are adapted to be embedded, and the bolt 300 is passed through the inner groove 113 and the outer boss 213.

[0051] Specifically, the inner groove 113, the outer boss 213 and the bolt 300 cooperate to increase the installation limit angle, limit strength and connection strength of the wear-resistant part 200, so that the wear-resistant part 200 has better structural strength and impact resistance and wear resistance.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
