[0032] The following will further elaborate on this application Figures 1-5 with reference to the attached drawings.

[0033] Embodiment 1:

[0034] An embodiment of this application discloses a single-shaft toothed crusher, as Figure 1 shown, which includes a box body 1 and a driving mechanism 7. A main shaft 5 is rotatably connected inside the box body 1, and the length direction of the main shaft 5 is consistent with the length direction of the box body 1. A plurality of hammer pieces 51 are fixedly connected to the main shaft 5; the driving mechanism 7 is used to drive the rotation of the main shaft 5. The driving mechanism includes a motor 71, a first synchronous pulley 72, a second synchronous pulley 73 and a timing belt 74. The motor 71 is installed on one side of the box body 1. The first synchronous pulley 72 is coaxially and fixedly connected to the output end of the motor 71. The second synchronous pulley 73 is coaxially and fixedly connected to the end of the main shaft 5 extending out of the box body 1. The first synchronous pulley 72 and the second synchronous pulley 73 are rotated simultaneously through the timing belt 74. An operator can drive the motor 71 to make the output shaft of the motor 71 drive the rotation of the first synchronous pulley 72, and the first synchronous pulley 72 drives the rotation of the second synchronous pulley 73 through the timing belt 74, so as to realize the rotation of the main shaft 5.

[0035] As Figure 2 and 3As shown in the figure, it further includes a mounting seat 2 and a fixed knife 3. There are two mounting seats 2, and the mounting seats 2 are welded to the inner wall of the box body 1; there are multiple fixed knives 3, and the fixed knives 3 are arranged in parallel along the length direction of the box body 1, and the fixed knives 3 are welded to the mounting seats 2. The hammer pieces 51 cooperate with the fixed knives 3. One fixed knife 3 is arranged between two hammer pieces 51, and one hammer piece 51 is arranged between two fixed knives 3. A positioning block 31 is integrally formed on the fixed knife 3. A first positioning hole 21 is opened on the mounting seat 2, and a second positioning hole 11 is opened on the inner wall of the box body 1. Both the first positioning hole 21 and the second positioning hole 11 are for the positioning block 31 to pass through. When installing the fixed knife 3, the operator moves the fixed knife 3 so that the positioning block 31 passes through the first positioning hole 21. The first positioning hole 21 can limit the positioning block 31, so that the fixed knife 3 and the mounting seat 2 are relatively positioned, and then the fixed knife 3 and the mounting seat 2 are welded. After the fixed knife 3 is installed on the mounting seat 2, the mounting seat 2 is installed in the box body 1. The mounting seat 2 is moved so that the mounting seat 2 fits against the inner wall of the box body 1, and the part of the positioning block 31 extending out of the first positioning hole 21 is embedded in the second positioning hole 11. The second positioning hole 11 can limit the positioning block 31, so that the mounting seat 2 and the box body 1 are relatively positioned, and then the mounting seat 2 and the box body 1 are welded, thereby realizing the installation of the mounting seat 2 and the fixed knife 3, facilitating the cooperation between the fixed knife 3 and the hammer pieces 51 to crush the material.

[0036] As Figure 4 shown in the figure, a material screening frame 4 is provided in the box body 1. The material screening frame 4 is located below the main shaft 5. The material screening frame 4 includes a fixing plate 41, a partition rod 42 and a partition plate 43. The fixing plate 41 is detachably connected to the box body 1. There are two fixing plates 41, one is located on the inner wall at one end of the box body 1, and the other is located on the inner wall at the other end of the box body 1. A connecting bolt 12 is provided on the box body 1. The connecting bolt 12 passes through the box body 1 and is threadedly connected to the fixing plate 41, and the connecting bolt 12 abuts against the box body 1. When installing the fixing plate 41, after moving the fixing plate 41 to a suitable position on the inner wall of the box body 1, the connecting bolt 12 is screwed in so that the connecting bolt 12 passes through the box body 1 and is threadedly connected to the fixing plate 41. The connecting bolt 12 can limit the fixing plate 41, so that the fixing plate 41 and the box body 1 are fixed, thereby realizing the installation of the fixing plate 41.

[0037] There are multiple separating rods 42, and both ends of the multiple separating rods 42 are fixedly connected to the fixing plate 41. The length direction of the separating rod 42 is consistent with the length direction of the main shaft 5. There are multiple separating plates 43, and the multiple separating plates 43 are arranged in parallel along the length direction of the separating rod 42. The separating plate 43 is located below the separating rod 42 and is fixedly connected to the separating rod 42. Sieve holes 44 are formed between two adjacent separating rods 42 and two adjacent separating plates 43; several embedding grooves 431 are formed on the separating plate 43, and the embedding grooves 431 are for the separating rod 42 to be embedded.

The separating rod 42 can limit the separating plate 43, facilitating the installation of the separating plate 43 onto the separating plate 43, and thus facilitating the material to pass through the sieve holes 44.

[0038] The implementation principle of a single-shaft toothed crusher in an embodiment of the present application is as follows:

[0039] An operator can drive the rotation of the main shaft 5 through the motor 71. The rotation of the main shaft 5 can drive the rotation of the hammer blades 51. The material is crushed under the action of the hammer blades 51 and the fixed cutter 3, and then the material is discharged from the box body 1 through the sieve holes 44.

When installing the separating rod 42, move the separating rod 42 so that both ends of the separating rod 42 are embedded in the limiting grooves 61. The limiting grooves 61 can limit the separating rod 42, enabling the relative positioning of the separating rod 42 and the installation frame 6, thereby realizing the installation of the separating rod 42. When installing the separating plate 43, move the separating plate 43 to a suitable position, and then connect the angle code 432 to the separating rod 42 through bolts, facilitating the positioning installation of the separating plate 43 and improving the connection stability of the separating plate 43.

[0042] The implementation principle of a single-shaft toothed crusher in an embodiment of the present application is as follows:

[0043] The operator can disassemble and clean the partition rod 42 or the partition plate 43 to improve the surface cleanliness of the two and facilitate the passage of materials through the sieve holes 44; when installing the partition rod 42, move the partition rod 42 so that both ends of the partition rod 42 are embedded in the limit groove 61 to complete the installation of the partition rod 42; when installing the partition plate 43, after moving the partition plate 43 to the appropriate position, connect the angle code 432 to the partition rod 42 through bolts, thereby completing the installation of the partition plate 43.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby.
