[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] First Embodiment

[0034] Please see Figures 1-3 This utility model provides a technical solution: a blade-type crushing roller, including a main roller 2, on which multiple sets of blade crushing mechanisms 1 are arranged;

[0035] The blade crushing mechanism 1 includes a mounting sleeve 11, which is fitted onto the main roller 2. Nine sets of blade assemblies 12 are arranged alternately on the mounting sleeve 11, with each pair of blade assemblies 12 arranged at a 40° angle. Locking bolts 13 are provided on the mounting sleeve 11, with one end of the locking bolts 13 connected to the main roller 2. The locking bolts 13 enable the mounting sleeve 11 to be quickly fixed to the main roller 2.

[0036] First, the mounting sleeve 11 is fitted onto the main roller 2. Then, the mounting sleeve 11 is fixed onto the main roller 2 by the locking bolt 13. Multiple sets of blade crushing mechanisms 1 are then fixed onto the main roller 2 in sequence. When the crushing and screening bucket is working, the main roller 2 is driven to rotate by the drive mechanism. The main roller 2 simultaneously drives multiple sets of blade crushing mechanisms 1 to rotate synchronously. The mounting sleeve 11 simultaneously drives 9 sets of blade assemblies 12 to rotate. Since the blade assemblies 12 are at a 40° angle to each other, each set of blade assemblies 12 can continuously screen and crush sand and stones when rotating in sequence.

[0037] Second Embodiment

[0038] Please see Figure 4 The blade assembly 12 includes a crushing blade 128, which is mounted on the mounting sleeve 11. An alloy crushing head 121 is provided at the end of the crushing blade 128. The main roller 2 drives the mounting sleeve 11 to rotate, which in turn drives the crushing blade 128 to rotate. The rotation of the crushing blade 128 drives the alloy crushing head 121 to rotate. The alloy crushing head 121 improves the wear resistance of the end of the crushing blade 128 and enhances the crushing effect of sand and stones. The end of the alloy crushing head 121 has a rounded structure, which ensures the smoothness of the end and enables rapid screening of sand and stones, thereby improving screening efficiency.

[0039] Third Embodiment

[0040] Please see Figures 4-6 The alloy crushing head 121 is provided with auxiliary crushing blocks 122 on both sides. The auxiliary crushing blocks 122 are detachably mounted on the alloy crushing head 121. When the crushing blade 128 rotates, the crushing blade 128 drives the alloy crushing head 121 to rotate, and the alloy crushing head 121 drives the auxiliary crushing blocks 122 to rotate. When the auxiliary crushing blocks 122 rotate, they can perform multi-stage crushing of sand and stones, improving the crushing effect. Specifically, the auxiliary crushing blocks 122 and the alloy crushing head 121 are both made of the same alloy material, which ensures the mechanical strength of the auxiliary crushing blocks 122.

[0041] Fourth embodiment

[0042] Please see Figures 4-6 A threaded positioning sleeve 124 is provided on one side surface of the auxiliary crushing block 122. The threaded positioning sleeve 124 is connected to the positioning groove 125. When the auxiliary crushing block 122 is installed, the threaded positioning sleeve 124 on the auxiliary crushing block 122 is inserted into the positioning groove 125, which can quickly position the auxiliary crushing block 122 on the alloy wear-resistant head.

[0043] Specifically, a threaded hole 127 is provided at the bottom of the positioning groove 125, and a fixing bolt 126 is provided in the threaded positioning sleeve 124. The fixing bolt 126 is connected to the threaded hole 127, which can lock and fix the secondary crushing block 122 to the alloy crushing head 121, and at the same time facilitate the replacement of the secondary crushing block 122.

[0044] After the threaded positioning sleeve 124 on the secondary crushing block 122 is inserted into the positioning groove 125, the fixing bolt 126 is installed in the threaded positioning sleeve 124. The fixing bolt 126 is rotated, and the fixing bolt 126 rotates and moves in the threaded positioning sleeve 124, so that the fixing bolt 126 is connected to the threaded hole 127, thus fixing the secondary crushing block 122. When the secondary crushing block 122 is worn or damaged, the fixing bolt 126 can be separated from the secondary crushing block 122, and the secondary crushing block 122 can be disassembled and replaced.

[0045] Furthermore, the end of the fixing bolt 126 is set in the countersunk groove 123, which is set on one side surface of the auxiliary crushing block 122.

[0046] By using countersunk holes, the fixing bolt 126 can be installed in a concealed manner, preventing damage or loosening.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
