specific Embodiment 1

[0034] Specific embodiment one. refer to Figure 1 to Figure 5 , the first embodiment of the present invention will be described.

[0035] The drive motor 1 of the eccentric grinder is connected with the input shaft 3 through the belt transmission device 2; the input shaft 3 and the output shaft 5 are respectively connected with both ends of the universal joint 4, and the transmission eccentric block 6 is fixed on the output shaft 5 and the two The center of gravity is not on a straight line in the vertical direction; according to the different fixed positions of the transmission eccentric block 6, two embodiments of the present invention are formed, and the positions are as follows image 3 and Image 6 . The grinding platform 11 has a hollow base, the hollow base is fixedly connected with the sleeve 8, the upper surface of the sleeve 8 has a circular hole in the center, and the bearing 7 at the lower part of the output shaft 5 just falls into the hole. The table surface ...

specific Embodiment 2

[0038] Specific embodiment two. The difference from Example 1 is that Image 6 , the lower surface of the grinding platform 11 is tightly pressed on the transmission eccentric block 6. At this time, friction will be generated between the two. Since the transmission eccentric block 6 is driven by the output shaft 5 and rotates at a variable speed at the same time, under the action of friction, the grinding Platform 11 just shakes constantly in horizontal direction, produces larger amplitude; Output shaft 5 makes irregular circular motion around itself at the same time, will produce height difference in vertical direction, add the gravity of grinding platform and its upper part itself, grinding The platform 11 also generates vibration amplitude in the vertical direction at the same time. As a result, the grinding platform 11 generates vibration amplitudes in the horizontal direction and the vertical direction, causing the grinding disc to continuously collide with the bowl, so ...

Abstract

The invention relates to an eccentric grinding machine, which comprises a driving device, a transmission device, an input shaft, a universal joint, an output shaft, a bearing, a transmission eccentric block, a sleeve, a main body support device, springs, a grinding platform, a material bowl, a material bowl cover, a grinding disk and a material bowl fastening device, wherein the driving device is connected with the input shaft by the transmission device; the input shaft and the output shaft are connected with two ends of the universal joint respectively; the transmission eccentric block is fixed on the output shaft; gravity centers of the transmission eccentric block and the output shaft are in a vertical direction but not on the same straight line; the grinding platform is provided with a hollow base; the hollow base is fixedly connected with the upper surface of the sleeve; a round hole is formed in the center of the upper surface of the sleeve; the bearing at the lower part of the output shaft is exactly positioned in the hole; the platform surface of the grinding platform is uniformly connected with the main body support device by a plurality of springs in a circumferential direction; the material bowl is fixed on the grinding platform by the material bowl fastening device; the grinding disk is arranged in a cavity of the material bowl; and the material bowl cover is tightly covered on the material bowl. The eccentric grinding machine has the advantages of small volume, low noise, low requirements on environmental conditions and high grinding efficiency.

Description

technical field [0001] The present invention relates to a grinder, in particular to an eccentric grinder used for sample grinding of coal, ore and other bulk goods. Background technique [0002] The grinding machine is mainly used in the grinding process of sampling inspection of ores, minerals, metallographic samples, ceramic products, soil, mixtures, chemicals and similar materials, and is an important part of the sampling inspection process. [0003] When conducting international and domestic trade transactions of ores, minerals and other bulk cargoes, strict quantitative analysis of the entire delivery batch is required to determine the quality of the delivery batch. The sampling and inspection process of samples plays a very critical role in determining whether the quality identification of the delivered batch is accurate and representative. The grinder is one of the most critical equipment in the sample preparation process. Whether there is deviation during sample pr...
