Abstract
The utility model relates to a novel sealed sample pulverizer, which comprises a stand, a motor, a eccentric weight, a vibrating spring, an upper cover, a coupling sleeve, a pulverization device and a pressing device, and is characterized in that the output shaft of the motor is provided with two rows of bearing connectors; the two rows of bearing connectors are formed by assembling a bearing block with a I-shaped section and two bearings; the outer edge of the upper end surface of the I-shaped bearing block is connected with the upper cover; and the eccentric weight is arranged on the tail end of the output shaft of the motor. The novel sealed sample pulverizer can eliminate the impact the centrifugal force of the bearing on the shaft end of the motor, makes the running more stable, reduces the power consumption of rotational motion, increases the speed of pulverizing sample, improves the working efficiency of the device, reduces the workload of the maintenance, and prolongs the service life of the bearing.
Description
Technical field
The utility model relates to the coal production equipment technical field, particularly relates to a kind of novel seal formula sample pulverizer.
Background technology
Ature of coal analysis and sample making pulverizer be adopt, visual plant that system, chemical industry make to make in the link coal sample.At present, sample pulverizer commonly used has MZD-1 and two kinds of models of FZ-1/100A, and they all are that off-centre is got rid of piece formula sampling machine, and rotating speed reaches 1450 rev/mins during operation.But because eccentric block all adopts single armed overarm formula support structure, thereby in high speed circular motion like this, the centrifugal force of eccentric block is excessive, makes the bearing block undercapacity, the bearing faults such as frame, support fracture that fall often occur, and causes producing and pauses.
Summary of the invention
The purpose of this utility model just is to overcome the defective of above-mentioned prior art, provides the impact of a kind of effective elimination centrifugal force to eccentric block, even running, the sealed sample pulverizer of long service life.
The utility model is achieved through the following technical solutions:
A kind of sealed sample pulverizer, comprise frame, motor, eccentric hammer, vibrating spring, loam cake, coupling sleeve, reducing mechanism and hold down gag, it is characterized in that: double row bearing connector is installed on the output shaft of described motor, this double row bearing connector be by the cross section be I-shaped bearing block and two the dish bearings be assembled, the upper surface outward flange of I-shaped bearing block is connected with loam cake; Eccentric hammer is installed in the end of motor output shaft.
The outstanding amount of single armed in the original sealed sample pulverizer of the utility model in this high speed rotary structure changes the duplex bearing seat supports into, the revolution centrifugal force of eccentric block is transferred on the vibrating spring dish by I-shaped bearing block, eliminated the impact of motor shaft end bearing centrifugal force, again because the vibrating spring dish has increased one group of parts newly, weight increases, and makes operation more steady, and the gyration power consumption reduces, the speed of pulverizing sample preparation improves, and prolongs the service life of bearing simultaneously.
Sealed sample pulverizer of the present utility model is along with former machine bearing fall frame, support fracture damage troubleshooting of faults, can shorten sample preparation time 6-7 second, raising equipment operating efficiency, reduce maintenance load, for adopt, system, chemical industry do that sample preparation work provides satisfactory sample in the link, for dynamically instructing the coal washing production operation that reliable guarantee is provided, the service life of also having improved grinding and crushing machine simultaneously.
Description of drawings
Fig. 1 is the structural representation sketch of the sealed sample pulverizer of the utility model.
The specific embodiment
Sealed sample pulverizer of the present utility model is the improvement on original MZD-1 and FZ-1/100A type sample pulverizer, its structure comprises frame 1, motor 2, eccentric hammer 3, vibrating spring 4, loam cake 5, coupling sleeve 6, reducing mechanism and hold down gag, the top of loam cake 5 is fixed with the reducing mechanism that impact block 9, impact ring 10 etc. are formed, improvements of the present utility model are motor output shaft 7 lengthenings, double row bearing connector and eccentric hammer 3 are installed thereon successively, and eccentric hammer 3 is installed in the end of motor output shaft 7.Described double row bearing connector be by the cross section be I-shaped bearing block 8 and two the dish bearings 11 be assembled, the upper surface outward flange of I-shaped bearing block 8 is connected with loam cake 5.The utility model can satisfy instructions for use under the prerequisite that does not change the original equipment important technological parameters.
