[0041] Working principle:

[0042] In the first step, the user can open the box cover 23 when carrying the stone material, put the stone material into the crushing box 2, and cover the box cover 23, start the first motor 25 when it is necessary to crush the stone material, the first motor 25 drives the transmission rotating rod 3 to rotate, the transmission rotating rod 3 drives the first crushing blade 81 or the second crushing blade 71 on the transmission rotating rod 3 to crush the stone material, the second crushing blade 71 is used to crush large pieces of stone material, and the first crushing blade 81 is used to crush small pieces of stone material, and the crushed materials can be discharged through the discharge pipeline on the crushing box 2 after crushing is completed.

[0043] Second, in the process of crushing the gravel material put into the carrying pallet 1, there are large and small pieces of gravel material. In the preliminary crushing, the second crushing blade 71 can be used to crush the large pieces of gravel material. When the second crushing blade 71 is used to crush the gravel material, the user can start the second motor 51, which drives the threaded rod 53 to rotate, and the threaded rod 53 drives the movable push plate 6 to move up through the threaded groove 61. The movable push plate 6 moves up to drive the two sides of the L-shaped rod 63 to move up, and the L-shaped rod 63 moves up to drive each first push rod 64 and second push rod 65 to move up. When the first push rod 64 moves up, the first push rod 64 slides in the first rectangular notch 73, and at this time the first push rod 64 drives the first L-shaped side rod 72 to rotate through the first rectangular notch 73. The first L-shaped side rod 72 rotates to drive the second crushing blade 71 to rotate around the second rotating rod 7, and the second crushing blade 71 rotates to gradually move away from the inner side wall of the second storage slot 33. When each second crushing blade 71 rotates completely away from the inner side wall of the second storage slot 33, the adjustment is completed, and the user can start the first motor 25 to drive the second crushing blade 71 on the transmission rotating rod 3 to crush the gravel material.

[0044] The second crushing blade 71 is a whole blade with a large volume and high rigidity, which has better crushing force when crushing large pieces of gravel, and can meet the rigid demand for crushing large pieces of gravel material.

[0045] In the third step, after the preliminary crushing of the second crushing blade 71, the second crushing blade 71 may not completely crush some small pieces of gravel material due to its large volume. At this time, the user can use the first crushing blade 81 to crush, and the user can start the second motor 51 to drive the threaded rod 53 to rotate in the opposite direction, thereby driving the movable push plate 6 to move down, and the movable push plate 6 drives the first push rod 64 and the second push rod 65 on the L-shaped rod 63 to move down. The second push rod 65 moves down to drive the second L-shaped side rod 82 to rotate through the second rectangular notch 83, and the second L-shaped side rod 82 rotates to drive the first crushing blade 81 on the first rotating rod 8 to rotate and gradually move away from the inner side wall of the second storage slot 33. When the first crushing blade 81 rotates completely away from the inner side wall of the first storage slot 31, the adjustment is completed, and the user can start the first motor 25 to drive the first crushing blade 81 on the transmission rotating rod 3 to crush the gravel material.

[0046] The first crushing blade 81 is a combination of multiple blades, which can ensure complete crushing of small pieces of gravel material and meet the demand for complete crushing of small pieces of gravel material.

[0047] Fourthly, when the blade is switched, the second push rod 65 and the first push rod 64 are simultaneously moved up or down by the back-shaped rod 63, and the second crushing blade 71 and the first crushing blade 81 are simultaneously rotated when the second push rod 65 and the first push rod 64 are moved, so that the first crushing blade 81 is rotated and stored in the inner side wall of the first storage groove 31 by the movement of the second push rod 65 when the second crushing blade 71 is gradually rotated away from the inner side wall of the second storage groove 33, and the second crushing blade 71 is rotated and stored in the inner side wall of the second storage groove 33 by the movement of the first push rod 64 when the first crushing blade 81 is gradually rotated away from the inner side wall of the first storage groove 31.

[0048] By the alternate use of the first crushing blade 81 and the second crushing blade 71, the first crushing blade 81 is stored in the second storage groove 33 using the second crushing blade 71, and the second crushing blade 71 is stored in the first storage groove 31 using the first crushing blade 81, so that the first crushing blade 81 or the second crushing blade 71 can be stored in the first storage groove 31 or the second storage groove 33, respectively, when they are not used, avoiding contact with the stone and wear, and prolonging the service life.

[0049] Fifthly, a plurality of damping pads 13 are arranged at the lower end of the crushing box 2, which has a good protective buffering effect on the crushing box 2, avoids rigid contact between the crushing box 2 and the carrying pallet 1, and causes damage to the crushing box 2 and the carrying pallet 1 due to the large vibration generated during crushing, and a shock-absorbing foam plate 11 is arranged on the carrying pallet 1, so that the user is less affected by the vibration of the crushing box 2 when pushing the crushing box 2 for transfer, and the device is provided with soundproof cotton 22 in the annular mounting groove 21 in the crushing box 2, which has a good soundproof effect and reduces the noise pollution generated by the crushed stone materials in the crushing box 2 during the transfer process.
