Abstract
The utility model relates to the field of crushers and particularly relates to a pin roll type secondary crusher. The crusher comprises a rack and pin rolls rotatably assembled on the rack, wherein the pin rolls are in transmission connection with a driving device, the pin rolls are divided into a pair of upper pin rolls and a pair of lower pin rolls corresponding to the upper pin rolls, the upper pin rolls are located right above the corresponding lower pin rolls, the upper and lower pin rolls are mutually parallel to each other, the two upper pin rolls are synchronously and reversely connected together in a transmission manner, and the two lower pin rolls are synchronously and reversely connected together in a transmission manner. Since the upper pin rolls are located right above the corresponding lower pin rolls and the upper and the lower pin rolls are mutually parallel to each other, the upper pin rolls can be used as rough crushing rolls and the lower pin rolls are used as fine crushing rolls, when the crusher is used, materials to be crushed firstly pass by the upper pin rolls and are primarily crushed and are conveyed to the lower pin rolls, and the particle diameters of the materials arriving at the lower pin rolls are uniform, thereby fully achieving a crushing function of the lower pin rolls and solving the problem of easy blockage and low material crushing rate of the existing pin roll type secondary crusher.
Description
Technical field
The utility model relates to field of cracking machine, particularly relates to a kind of discaling roll formula secondary breaker.
Background technology
It is little that rod-toothed crusher has a volume, the ratio of reduction big (5-8), noise is low, simple in structure, easy to maintenance, the productivity ratio advantages of higher, because it is even by its broken raw meal particle size, it is low to cross degradation rate, so rod-toothed crusher is widely used in the fragmentation of industries, particularly large-scale colliery such as coal, metallurgy, mine, chemical industry, building materials or coal preparation plant's raw coal (containing spoil).
It is several that present toothed roll crusher mainly contains double-roll type (application number is 201120122094.1 Chinese patent), three-roller type (application number is 201020218018.6 Chinese patent) and four-roller type, though the quantity difference of their discaling roll, but but all be single-stage, the rotation of each discaling roll all is positioned on the same horizontal plane, when in use, material to be broken directly is placed in the top of discaling roll, is broken in the process in relative rotation at adjacent two discaling rolls.
Above-mentioned toothed roll crusher has obtained using very widely in actual production, but, in the process of using, because material to be broken is regardless of the place, top that size is completely all directly fallen same toothrow roller, when the big small drop of material to be broken is big, can't be very easily piled up at discaling roll by the big particle diameter material that discaling roll " is bitten ", and then cause the material of small particle diameter also can't fall smoothly, cause that finally material gathers obstruction, cause the damage of disintegrating machine; In addition, even material can fall smoothly, material particular diameter after the fragmentation of single-stage discaling roll often also can't meet the demands, and also needs further to carry out break process by miscellaneous equipment, and namely present toothed roll crusher is lower to the percentage of damage of material.
In sum, present toothed roll crusher exists easily obstruction and the problem low to the material percentage of damage.
Summary of the invention
The purpose of this utility model is to provide a kind of discaling roll formula secondary breaker, to solve easy obstruction that present toothed roll crusher exists and the problem low to the material percentage of damage.
In order to address the above problem, discaling roll formula secondary breaker of the present utility model is by the following technical solutions: discaling roll formula secondary breaker, comprise that frame and rotation are assemblied in the discaling roll on the frame, discaling roll is connected with drive unit, described discaling roll is divided into a pair of last discaling roll and a pair of lower gear roller corresponding with described last discaling roll, last discaling roll be positioned at it corresponding lower gear roller directly over and upper and lower discaling roll parallel to each other, go up being in transmission connection together of discaling roll synchronous backwards for two, being in transmission connection together of two lower gear roller synchronous backwards.
The top of frame fixedly is equipped with distributing device.
Two go up between the discaling rolls and two lower gear rollers between being in transmission connection together by corresponding gear synchronous backward respectively.
Drive unit is the motor that is connected with frequency converter.
The equal in length of upper and lower discaling roll.
Last discaling roll and lower gear roller are assemblied on the frame by corresponding yielding mechanism respectively.
Because the discaling roll of discaling roll formula secondary breaker of the present utility model is divided into a pair of last discaling roll and a pair of lower gear roller corresponding with described last discaling roll, in addition, last discaling roll be positioned at it corresponding lower gear roller directly over and upper and lower discaling roll parallel to each other, go up being in transmission connection together of discaling roll synchronous backwards for two, being in transmission connection together of two lower gear roller synchronous backwards; Therefore, can will go up discaling roll as the coarse crushing roller, with lower gear roller as the fine crushing roller, in use, material to be broken is at first through being arrived lower gear roller again after last discaling roll and the preliminary fragmentation of quilt, at this moment, because it is comparatively even to arrive the material particular diameter of lower gear roller, add material on leaving during discaling roll more or less meeting obtain the acceleration of discaling roll, therefore can give full play to the broken effect of lower gear roller, solves the easy obstruction of present toothed roll crusher existence and the problem low to the material percentage of damage.
Further, distributing device is used for material to be broken is guided to the discaling roll place along set path; But connect on the strict guarantee between the discaling roll and last discaling roll and the synchronism between lower gear roller and the lower gear roller by corresponding gear synchronous backward upper and lower discaling roll respectively; The motor that adopts the band frequency converter can be regulated the rotating speed of discaling roll as required at any time as drive unit, makes it give full play to broken effect; Make a concession mechanism and play the effect of protection discaling roll.

Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
The embodiment of discaling roll formula secondary breaker, as Figure 1-3, comprise frame 11, be rotatably equipped with discaling roll 12 on the frame 11, discaling roll has four, four discaling rolls in pairs, being divided into be positioned at the top a pair of goes up discaling roll and is positioned at the below, the a pair of lower gear roller corresponding with last discaling roll, go up between the discaling roll by being in transmission connection together of gear synchronous backward for two, between two lower gear rollers also by being in transmission connection together of gear synchronous backward, on, lower gear roller in separately is connected with drive unit by belt 17, in the present embodiment, drive unit adopts motor 13, and motor 13 is connected with frequency converter, can control the rotating speed of motor 13 by frequency converter; Last discaling roll be positioned at it corresponding lower gear roller directly over and their equal in length; In addition, last discaling roll and lower gear roller all are to be assemblied on the frame by corresponding yielding mechanism 14, and making a concession mechanism 14 is routine techniques in toothed roll crusher, no longer specifically describes its principle and structure herein; Upper and lower discaling roll all is housed among the casing 15, and casing 15 fixedly is assemblied on the frame 11, and its top fixedly is equipped with distributing device 16, and the discharge end of distributing device 16 is positioned at the place, top of discaling roll, and the structure of distributing device 16 is prior art, will not give unnecessary details herein.
