[0026] In this utility model, such as Figures 1 to 3As shown, a novel crushing and separating device is provided, including a horizontally placed separating cylinder 1 and a rotating shaft 2 disposed on the separating cylinder 1. The lower section of the separating cylinder 1 is provided with a screen hole 3. One end of the separating cylinder 1 is provided with a feed inlet 4 and the other end is provided with a discharge outlet 5. The separating device includes a conveying screw 7 disposed on the rotating shaft 2 at the feed inlet 4 position and a first crushing blade 6. The first crushing blade 6 is rotatably mounted on the rotating shaft 2. The separating device also includes a plurality of second crushing blades 8. The second crushing blades 8 are disposed on the part of the rotating shaft 2 between the feed inlet 4 position and the discharge outlet 5 position. The second crushing blade 8 includes a mounting base 801 fixed on the rotating shaft 2, a fixing rod 802 detachably mounted on the mounting base 801, and a blade 803 mounted on the fixing rod 802.

[0027] As shown in the figure, in use, the separation device of this utility model puts the waste to be processed into the feed inlet 4. When the waste enters the feed inlet, it is pushed towards the other end of the separation cylinder 1 by the conveying screw 7. The first crushing blade 6 performs preliminary crushing on the incoming waste, so that the clumps formed by hard inorganic and organic matter are broken down, reducing the number of large clumps when the waste enters the position of the second crushing blade 8. This reduces the resistance when the second crushing blade 8 rotates and crushes, thereby reducing the wear of the second crushing blade 8. At the same time, the first crushing blade 6 is set to be rotatable, so that the impact force on the first crushing blade 6 during the crushing process can be reduced, and the wear of the first crushing blade 6 can also be reduced.

[0028] In the illustrated embodiment, for the structure of this utility model, the rotating shaft 2 is provided with a U-shaped seat 9 at the position of the first crushing blade 6, the first crushing blade 6 is inserted into the inner side of the U-shaped seat 9, and the crushing device also includes a fixing bolt 10, which passes through the U-shaped seat 9 and the first crushing blade 6.

[0029] As shown in the figure, the inner end of the first crushing blade 6 is provided with a through hole through which the fixing bolt 10 passes, so that the first crushing blade 6 can buffer the impact of collision with the garbage by rotating around the fixing bolt 10 when crushing.

[0030] In the illustrated embodiment, a further optimization of the present invention is that the separating cylinder 1 is provided with a feed hopper 11 at the feed inlet 4.

[0031] As shown in the figure, by setting up the feed hopper 11, the amount of garbage in the separation cylinder 1 that splashes out from the feed port 4 can be reduced when the first crushing blade 6 crushes and decomposes the garbage.

[0032] In the illustrated embodiment, a further optimization of this invention is that the fixing rod 802 is threadedly screwed onto the mounting base 801. As shown, by screwing the fixing rod 802 onto the mounting base 801, the second crushing blade 8 can be easily disassembled and assembled, facilitating the replacement of worn crushing blades. It also allows for convenient adjustment of the angle of the blade 803 when installing the fixing rod 802.

[0033] In the illustrated embodiment, for the structure of this utility model, the separation device further includes a fixing nut 12 and a stop washer 13. The fixing nut 12 is screwed and fixed to the fixing rod 802, and the fixing nut 12 presses the stop washer 13 against the mounting base 801.

[0034] As shown in the figure, by setting a fixing nut 12 and a stop washer 13, the fixing rod 802 can be prevented from rotating after it is screwed and installed.

[0035] In the illustrated embodiment, to further specify the structure of this utility model, the separation device also includes a set screw 14, which is screwed and fixed by the side wall of the mounting base 801 and held against the fixing rod 802.

[0036] As shown in the figure, the fixed rod 802 is held in place by the set screw 14, which can further stop the rotation of the fixed rod 802.

[0037] In the illustrated embodiment, a further optimization of the present invention is that the separation device further includes a flushing pipe 15 disposed on the upper section of the separation cylinder 1.

[0038] As shown in the figure, by setting up a flushing pipe 15, water can be sprayed through the flushing pipe 15 during the crushing process of the second crusher 8 to promote the separation of organic and inorganic matter.

[0039] In the illustrated embodiment, a further optimization of this invention is that the upper section of the separating cylinder 1 is provided with an operating hole 16, and the separating cylinder 1 is provided with an openable and closable cover 17 at the operating hole 16. As shown in the figure, by providing the cover 17, it is convenient to inspect and replace the second crushing blade 8 inside the separating cylinder 1.

[0040] In the illustrated embodiment, regarding the installation method of the hole cover 17, more specifically, as shown in the figure, one end of the hole cover 17 is hinged to the separation cylinder 1, and the other end is connected by a latch 18.

[0041] As shown in the figure, the latch 18 includes a locking lug installed on the hole cover 17. The separating cylinder 1 is provided with a rotatable locking rod. After the hole cover 17 is closed, the locking lug is pressed and fixed by rotating the locking rod, thus completing the locking and closing of the hole cover 17.

[0042] In the illustrated embodiment, a further optimization of this invention is that the inner side of the hole cover 17 is provided with an inwardly protruding reinforcing rib 19. As shown in the figure, by providing the reinforcing rib 19, the structural strength of the hole cover 17 can be improved. Moreover, when the second crushing blade 8 rotates and drives the waste to rotate, the reinforcing rib 19 can act as a fixed blade, and can work together with the second crushing blade 8 to crush and pulp.

[0043] It should be noted that, Figure 3 One of the hole covers was removed, while the reinforcing ribs of the hole cover were retained, in order to demonstrate the structure.
