Description

A kind of double-roll crusher

Technical field

The utility model relates to a kind of ore reduction equipment, relates in particular to a kind of double-roll crusher.

Background technology

Double-roll crusher is a kind of machinery that is used for ore reduction, each serial double-roll crusher is widely used in the fragmentation of various materials in the laboratory, on the current market common double-roll crusher comprise frame, master and slave running roller, motor, with the power transmission of the motor transmission system to the running roller, be positioned at the funneling pay-off of running roller top and be positioned at the drawer type material collecting device of running roller below.The disintegrating machine motor of the type directly is connected with power supply, when big or hardness is high when the material viscosity of fragmentation, material can takes place usually stop up; the running roller stuck phenomenon in this case, must be cut off the electricity supply; manual backward rotation running roller is restarted disintegrating machine, relatively more dangerous, trouble after making material loosening.In addition, the material of pulverizing drops between running roller the material collecting device of drawer type voluntarily, manually takes out drawer then material is poured in the storage sample container.Because the drawer volume is bigger and heavy, outwards inconvenient operation and easy scratch arm during batch turning.

Summary of the invention

A kind of rewinding is convenient, safety for the technical problem that exists in the solution known technology provides for the utility model, and under the situation that occurs stopping up at material, does not need the double-roll crusher of shutdown operation.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of double-roll crusher, comprise frame, be installed on active roll and driven running roller, motor, transmission system on the frame, be positioned at the funneling pay-off of driving and driven running roller top and be positioned at the material collecting device of driving and driven running roller below, it is characterized in that, described material collecting device is a circumferential closed chute, the upper port of chute is fixed on the frame, and lower port is connected with the storage sample container; In addition, the control circuit that also comprises control motor forward and backward.

The utility model can also adopt following technical scheme:

Described chute is taper.

Described circuit for controlling motor is:

Be connected to wherein first contactor and second contactor on the two-phase of three phase mains, the normally-closed contact of first contactor is serially connected with on the branch circuit of second contactor, the normally-closed contact of second contactor is serially connected with on the branch circuit of first contactor, common port at above-mentioned two branch circuits is connected in series the time relay successively, thermal cut-off, the main contacts of first contactor is serially connected with between three phase mains and the motor, the main contacts of second contactor is anti-phase to be serially connected with between three phase mains and the motor, at the public output of above-mentioned two main contacts serial connection thermal cut-off, wherein one air switch is set on mutually at three phase mains.

Advantage and the good effect that the utlity model has are: adopt the chute type material collecting device, the lower port of material collecting device is connected with the storage sample container, and like this, the material by the running roller fragmentation directly enters the storage sample container along material collecting device, saved manpower, avoided the injury of material the people; On motor, connect the control circuit that makes its forward and backward, when material stops up, the motor counter-rotating, the material that enters running roller has been avoided running roller stuck by the slit between the backward rotation of the running roller hauling-out running roller.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the rearview of Fig. 1;

Fig. 3 is an electric control schematic diagram of the present utility model.

Among the figure: the 1-frame; The 2-active roll; The driven running roller of 3-; The funneling pay-off of 4-; The 5-motor; The 6-driving wheel; The 7-driven pulley; The 8-material collecting device; The 9-upper port; The 10-lower port; The 11-driving gear; The 12-driven gear; 13-storage sample container.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1-3, a kind of double-roll crusher comprises frame 1, is installed on active roll 2 and driven running roller 3 on the frame 1, the same side of master and slave running roller is coaxial fixedly connected driving gear 11 and driven gear 12 respectively, by the interlock between gear, master and slave running roller is oppositely with the speed running, at the coaxial connection driven pulley 7 of the other end of active roll 2, the motion of the driving wheel 6 that will be connected with motor 5 by conveyer belt is sent on the driven pulley 7.Funneling pay-off 4 is set above master and slave running roller, material collecting device 8 is set below master and slave running roller, described material collecting device 8 is circumferential closed chutes, and the upper port 9 of chute is fixed on the frame, and lower port 10 is connected with storage sample container 13.Chute is welded by steel plate in this enforcement, and for increasing the memory space of material in drawing mechanism, this chute is set to taper.Except that said structure, the control circuit that also comprises motor, this control circuit just can realized motor, reciprocal rotation, main composition is: be connected to the wherein first contactor KM1 and the second contactor KM2 on the two-phase of three phase mains, the normally-closed contact of the first contactor KM1 is serially connected with on the branch circuit of the second contactor KM2, the normally-closed contact of the second contactor KM2 is serially connected with on the branch circuit of the first contactor KM1, adopt said structure to form the interlocking of two control circuits, when the first contactor KM1 connects, the branch circuit of the second contactor KM2 disconnects, when in like manner the second contactor KM2 connects, the branch circuit of the first contactor KM1 disconnects, and has avoided connecting simultaneously forming short circuit.Common port at above-mentioned two branch circuits is connected in series time relay KT, thermal fuse F R1 successively.The main contacts of the first contactor KM1 is serially connected with between three phase mains and the motor 5; the main contacts of the second contactor KM2 is anti-phase to be serially connected with between three phase mains and the motor 5; public output serial connection thermal fuse F R2 at above-mentioned two main contacts; wherein one air switch QS is set on mutually at three phase mains, this switch is corresponding to the shutdown control button of equipment.Except that the control circuit of above-mentioned motor, the positive and negative control circuit of motor that adopts also is applicable to the utility model usually.
