Problems solved by technology
The disadvantage of this power transmission structure is that once a hard object is stuck between the hobs during cutting, first, it needs to be reversed, forward rotated, reversed, and forward rotated repeatedly until the hard object is removed before it can work normally. The second is that the transmission chain between the hob or two parallel hob shafts is easily damaged, which is one of the reasons for frequent accidents

Embodiment Construction
[0009] The specific implementation will be described in detail below in conjunction with the accompanying drawings: Figure 1 ~ Figure 2 A schematic diagram of the structure of the embodiment of the present invention is given. In the figure, a crushing power transmission device of a crusher includes: a crushing chamber 1, a motor 4 with a reduction box, a pair of hob rotating shafts 2 arranged in parallel on the side wall of the crushing chamber, and a pair of hob rotating shafts. The dial rotating shaft 3 that the axis is arranged in parallel, the first pair of sprockets 51,52, the first chain 53, the second pair of sprockets 61,62, the second chain 63; The right side is installed on the side wall of the crushing chamber 1 above the hob rotating shaft 2, and the connecting line between the center of the material turning shaft 3 and the shaft center of the hob rotating shaft 2 forms an inverted trumpet-shaped isosceles trapezoid, the isosceles The included angle B between the...

The invention relates to a crushing power transmission unit of a crusher. The crushing power transmission unit comprises a crushing chamber, a motor with a reduction gearbox, a pair of hobbing cutter rotation shafts parallely arranged on the sidewall of the crushing chamber, a pair of material-poking rotation shafts arranged to be parallel to the hobbing cutter rotation shafts, a first pair of a chain wheel and a chain and a second pair of a chain wheel and a chain. The invention has the following advantages: 1) since the material-poking rotation shafts are respectively mounted above the pair of the hobbing cutter rotation shafts of the crusher, a feed inlet is enlarged, mass production is realizable, and shearing efficiency is improved; 2) when a hard object is stuck between two hobbing cutters, the hobbing cutter at one side does not move while the hobbing cutter at the other side reverses, or the hobbing cutters at the two sides rotate along a reverse direction at the same time, so the stuck hard object can be easily removed, the hobbing cutters and the driving chain wheels can be effectively protected, and production can be resumed as fast as possible; and 3) since a pair of motors forming central symmetry are mounted on the sidewall of the crushing chamber, two transmission paths are distinct, the structure of the unit is simple, production cost is reduced, and the unit has a popularization value.
Description
Technical field: [0001] The invention relates to a treatment of solid waste materials, and more specifically relates to a crusher crushing power transmission device and a special hob structure. Background technique: [0002] Today, with the rapid economic development, the processing of large quantities of paper documents, and the processing of waste disks, tapes and boxes used to record information carriers are in increasing demand. The pre-process for these wastes is: collection and shredding . The working structure of the existing crusher hob mostly adopts the following structure: two groups of hobs composed of several blades arranged parallel to each other, the blades on each group of hobs are wedged between the two blades of the other hob, thus forming Shear shape to cut and break the information carrier to be processed. Its power transmission device is a two-stage transmission, the first-stage transmission is transmitted from the output shaft of the motor to the hob s...
