Description

Technical Field

[0001] This utility model relates to the field of grain crushing. Background Technology

[0002] The market now demands higher functionality from multi-pair toothed roller grain crushers, requiring a single machine to achieve different particle size requirements. One scenario involves crushing large-particle materials with just one pair of toothed rollers, while smaller-particle materials require two or more pairs. Current methods involve widening the gap between the lower pair of toothed rollers when processing larger-particle materials, allowing the material to pass directly through without secondary crushing, relying solely on the upper pair. When smaller-particle materials are needed, the gap is adjusted back to meet the required particle size. However, when different production tasks require frequently changing materials and multiple adjustments to the finished product particle size, adjusting the roller gap becomes extremely time-consuming (requiring machine downtime) and inefficient. Summary of the Invention

[0003] In order to solve the above-mentioned problems of existing multi-pair toothed roller grain crushers, this utility model provides a crusher material distribution mechanism.

[0004] The technical solution adopted by this utility model to achieve the above-mentioned objective is as follows: a crusher material distribution mechanism, wherein a material distribution shaft 7 is installed on the front and rear side housing 9 of the crusher between the upper toothed roller 10 and the lower toothed roller 12, one end of the material distribution shaft 7 is connected to a swing arm 2, the swing arm 2 is connected to a cylinder 4, the cylinder 4 is installed on the housing 9, and a material distribution plate 5 is installed on the material distribution shaft 7.

[0005] A fixed seat 1 is installed on the housing 9, and one end of the material distribution shaft 7 connected to the swing arm 2 is located inside the fixed seat 1.

[0006] The cylinder 4 is mounted on the cylinder support 8, and the cylinder support 8 is fixedly mounted on the housing 9.

[0007] The cylinder 4 is connected to the swing arm 2 via the cylinder connector 3.

[0008] The material distribution mechanism of this invention enables rapid switching between single and multiple pairs of toothed rollers on the equipment without stopping the machine or adjusting the gap between the lower rollers, thus meeting the processing requirements of different material particle sizes during the crushing process and improving production efficiency.

[0014] The crusher feeding mechanism of this utility model is as follows: Figure 1 and 2 As shown, the material distribution mechanism 11 is installed between the upper and lower pairs of rollers. A power source cylinder 4 is used, and the cylinder 4 is fixed to the equipment housing 9 by a cylinder support 8 and connecting bolts 6. The cylinder 4 is connected to a cylinder connector 3, which is connected to a swing arm 2. The swing arm 2 is connected to a material distribution shaft 7, which is fixed to a material distribution plate 5. The material distribution shaft 7 is also connected to the equipment housing 9 via a fixed seat 1. The material distribution shaft 7 can only rotate and cannot move radially. When the cylinder 4 receives power from the air source, the cylinder piston rod extends and retracts. Through the linkage of the swing arm 2, cylinder connector 3, and material distribution shaft 7, the material distribution plate 5 rotates at a certain angle. When the cylinder piston rod pushes forward, the material distribution plate 5 contacts the left side of the housing and stops moving. At this point, the material is not processed by the lower pair of toothed rollers 12, and the upper pair of toothed rollers 10 is crushed. Figure 4 As shown. When the cylinder piston rod retracts, the material distribution plate 5 rotates clockwise and stops moving after contacting the right side of the housing 9. At this time, the material crushed by the upper toothed roller 10 flows directly to the lower toothed roller 12 for secondary crushing, realizing the crushing function of multiple toothed rollers, as shown. Figure 3 As shown.

[0015] When in use, the material flow changes depending on the position of the material distribution mechanism, allowing for rapid switching between single-pair and multi-pair toothed rollers on a single machine without shutting down the machine. By adding this material distribution mechanism to the crusher, downtime for adjustments is significantly reduced and production efficiency is improved when switching between single-pair and multi-pair toothed rollers is required.
