[0020] Embodiment 1:

[0021] See also Figure 1-Figure 3 As shown, a toothed roller shaft spacing adjustment device for material screening comprises a roller crusher body 1, wherein rows of screen shafts 2 are arranged inside the roller crusher body 1, materials of different sizes are screened through the rows of screen shafts 2, and relatively large materials fall between toothed roller shaft roller 1 3 and toothed roller shaft roller 2 4, and toothed roller shaft roller 1 3 and toothed roller shaft roller 2 4 are arranged inside the roller crusher body 1 and on one side of the screen shaft 2, and a fixing block 5 is installed outside the roller crusher body 1 and at the toothed roller shaft roller 1 3 and the toothed roller shaft roller 2 4, and a driving motor is arranged at the end of the toothed roller shaft roller 2 4. The driving motor drives the gear roller shaft roller 2 4 and the gear roller shaft roller 1 3 to rotate, so that the gear roller shaft roller 1 3 and the gear roller shaft roller 2 4 can crush some relatively large materials. The two ends of the gear roller shaft roller 1 3 and the gear roller shaft roller 2 4 are respectively provided with a spacing adjustment structure 6, and the two spacing adjustment structures 6 are respectively located at the two side walls of the roller crusher body 1. The gear roller shaft roller 1 3 and the gear roller shaft roller 2 4 pass through the interior of the two spacing adjustment structures 6. The spacing adjustment structure 6 includes a gear 1 62 and a gear 2 63. The gear 1 62 is arranged at one end of the gear roller shaft roller 2 4, and the gear 2 63 is arranged at At one end of the toothed roller shaft roller 13, gear 1 62 and gear 2 63 are arranged in pairs, and gear 1 62 of the toothed roller shaft roller 2 4 drives gear 2 63 of the toothed roller shaft roller 1 3 to rotate, so that the toothed roller shaft roller 1 3 and the toothed roller shaft roller 2 4 rotate with each other, which can crush relatively large materials. One end of the toothed roller shaft roller 1 3 and the gear 2 63 are sleeved with a movable seat 65, and the bottom end of the movable seat 65 is slidably connected to the surface of the roller crusher body 1, and one end of the toothed roller shaft roller 2 4 and the gear 1 62 are sleeved with a fixed seat 64, and the bottom end of the fixed seat 64 is fixed to the surface of the roller crusher body 1 A telescopic rod 68 is arranged between the fixed seat 64 and the movable seat 65. By changing the length of the two telescopic rods 68 on both sides of the roller crusher body 1, the two movable seats 65 can be moved, thereby changing the spacing between the gear roller shaft roller 1 3 and the gear roller shaft roller 2 4, and the two side walls of the roller crusher body 1 are provided with reserved grooves for moving the gear roller shaft roller 1 3, and the spacing is smaller than the meshing gap distance between the gear 1 62 and the gear 2 63, thereby changing the spacing between the gear roller shaft roller 1 3 and the gear roller shaft roller 2 4, and the materials crushed by the gear roller shaft roller 1 3 and the gear roller shaft roller 2 4 can be adjusted.

[0022] In this embodiment, a support seat 66 is provided on the surface of the roller crusher body 1 and on one side of the fixed block 5. A threaded rod 67 is provided in the middle of the support seat 66. The threaded rod 67 is threadedly connected to the support seat 66. The movable seat 65 is located between the threaded rod 67 and the telescopic rod 68. The threaded rod 67 can be rotated when the telescopic rod 68 is extended or retracted. The threaded rod 67 and the telescopic rod 68 are used to clamp the position of the movable seat 65 to avoid position changes during the operation of the equipment.

[0023] In this embodiment, the tooth gap between gear 1 62 and gear 2 63 is adapted to the telescopic length of the telescopic rod 68, and the sliding length of the movable seat 65 is smaller than the telescopic length of the telescopic rod 68, so as to avoid the situation where the telescopic length of the telescopic rod 68 is too long so that the gap between gear 1 62 and gear 2 63 is too large to engage.

[0024] In this embodiment, a connecting plate is installed on one side of the support seat 66, and a threaded rod 67 passes through the interior of the connecting plate. A telescopic spring 69 is connected between the connecting plate and the support seat 66. The threaded rod 67 is screwed into the support seat 66, so that the end of the threaded rod 67 can clamp the movable seat 65 tightly, and the telescopic spring 69 pulls the connecting plate to prevent the movable seat 65 at the end of the threaded rod 67 from loosening.

[0025] In this embodiment, two bearings 61 are arranged inside the fixed block 5, and the positions of the two bearings 61 correspond to the gear roller shaft roller 1 3 and the gear roller shaft roller 2 4 respectively. The two bearings 61 of the fixed block 5 are rotationally connected with the gear roller shaft roller 1 3 and the gear roller shaft roller 2 4.

[0026] When the utility model is in use, the material is put into the roller crusher from the top loading port of the main body 1, and the material is screened between the screen shafts 2, so that the materials of different sizes can fall into the gap between the screen shafts 2, and the relatively large materials fall between the toothed roller shaft roller 1 3 and the toothed roller shaft roller 2 4, so that the materials between the toothed roller shaft roller 1 3 and the toothed roller shaft roller 2 4 are crushed into relatively small ones by the toothed roller shaft roller 1 3 and the toothed roller shaft roller 2 4. When the size of the crushed material needs to be changed, the distance between the toothed roller shaft roller 1 3 and the toothed roller shaft roller 2 4 can be adjusted, specifically, the distance between the toothed roller shaft roller 1 3 and the toothed roller shaft roller 2 4 can be adjusted. The retractable rod 68 is extended and retracted, so that the gear roller shaft roller 1 3 is away from the gear roller shaft roller 2 4, the gear roller shaft roller 2 4 and the fixed seat 64 are fixed on the roller crusher body 1, and the extension and retraction of the telescopic rod 68 will move the movable seat 65, and the gear roller shaft roller 1 3 between the two movable seats 65 can move the roller crusher body 1, and the rotating threaded rod 67 can rotate. The moved movable seat 65 can be fixed by the threaded rod 67 and the telescopic rod 68, and the connecting plate is frozen by the telescopic spring 69 to prevent the thread of the threaded rod 67 from loosening, and the size of the crushed material can be adjusted by changing the distance between the gear roller shaft roller 1 3 and the gear roller shaft roller 2 4.
