Description
Technical field
The utility model belongs to pulverizer equipment technical field, more particularly to a kind of pulverizer hydraulic cylinder.
Background technology
According to the difference for crushing material or material, the requirement to pulverizer is also different.Current pulverizers many on the market are all
It is that drive device is used as by the way of motor acceleration and deceleration machine, one pulverizer of a motor connection, operating efficiency is limited.Simultaneously
During crushing, when because of solid accumulation or running into the harder material of material, it is easy to cause card machine, severe patient can also burn out
Motor, many troubles are brought to operating personnel.
Therefore, above-mentioned technical problem how is overcome to become those skilled in the art's technical problem urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is just to provide a kind of pulverizer hydraulic cylinder, can be fully solved above-mentioned prior art not
Foot part.
The purpose of this utility model is realized by following technical proposals：
A kind of pulverizer hydraulic cylinder, including cylinder body, drive device and connecting rod, the drive device are connected to
On cylinder body, the cylinder body is made up of the opposite single-column plug cylinder of two directions of motion, one end of the connecting rod
It is connected on the cylinder cap of a single-column plug cylinder, the other end of connecting rod is connected on the cylinder cap of another single-column plug cylinder, the driving dress
Put and pass through connection respectively including oval cam, connecting shaft, the first roller and the second roller, first roller and the second roller
For axis connection on the cylinder cap of single-column plug cylinder, the oval cam end face is provided with groove, and the first roller is set in groove, described
Second roller is arranged on the side of oval cam, and the middle part of the oval cam is provided with transmission shaft mounting hole, described ellipse
Circular cam rotates a circle, and single-column plug cylinder comes and goes two back and forth just.
Preferably, the oval cam is made of high manganese steel material.The anti-wear performance of potassium steel is good, is advantageous to
One roller and the second roller roll around on oval cam.
Preferably, the cylinder body and connecting rod external coating have anticorrosive coat.Anticorrosive coat is advantageous to protect hydraulic pressure
Cylinder body and connecting rod are not corroded, and extend its service life.
Compared with prior art, the beneficial effects of the utility model are：It is simple in construction, it is reasonable in design, using two sides
Linked together to opposite single-column plug cylinder and drive the ingehious design of oval cam, two pulverizers can be driven simultaneously, saved
Motor and speed reducer, its is powerful, and operating efficiency is high, is not in card machine, the phenomenon to crash.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference：Cylinder body（1）, drive device（2）, single-column plug cylinder（3）, oval cam（4）, connecting shaft
（5）, the first roller（6）, the second roller（7）, groove（8）, transmission shaft mounting hole（9）, connecting rod（10）.
Embodiment
The utility model is further described with reference to specific embodiments and the drawings.
As shown in figure 1, a kind of pulverizer hydraulic cylinder, including cylinder body 1, drive device 2 and connecting rod 10, it is described
Drive device 2 is connected on cylinder body 1.The cylinder body 1 is by 3 groups opposite of single-column plug cylinder of two directions of motion
Into one end of the connecting rod 10 is connected on the cylinder cap of a single-column plug cylinder 3, and the other end of connecting rod 10 is connected to another single-column
On the cylinder cap of plug cylinder 3.Mutual back and forth movement can be carried out between two such single-column plug cylinder 3.When a single-column plug cylinder 3 injects hydraulic pressure
During oily pushing piston-rod, the direction of motion of another single-column plug cylinder 3, i.e. piston rod are withdrawn in cylinder barrel, discharge hydraulic oil.The driving
Device 2 includes oval cam 4, connecting shaft 5, the first roller 6 and the second roller 7, and the roller 7 of the first roller 6 and second divides
It is not connected to by connecting shaft 5 on the cylinder cap of single-column plug cylinder 3.The end face of oval cam 4 is provided with groove 8, is set in groove 8
The first roller 6 is put, second roller 7 is arranged on the side of oval cam 4.The middle part of the oval cam 4 is provided with
Shaft mounting hole 9 is driven, the power transmission shaft of pulverizer is installed.The oval cam 4 rotates a circle, and single-column plug cylinder 3 comes and goes two just
It is individual in order to realize continual and steady power, to make to can be good at coordinating between cylinder body 1 and drive device 2 back and forth, it is oval
One week must is fulfilled between shape cam 4 and single-column plug cylinder 3 to two ratios back and forth.
The oval cam 4 is made of high manganese steel material.The anti-wear performance of potassium steel is good, is advantageous to the first roller 6
Rolled around with the second roller 7 on oval cam 4.
The cylinder body 1 and the external coating of connecting rod 10 have anticorrosive coat.Anticorrosive coat is set to be advantageous to protect hydraulic cylinder
Body 1 and connecting rod 10 are not corroded, and extend its service life.
Operation principle of the present utility model is the oil-feed of a single-column plug cylinder 3, promotes connecting rod 10 to move out, connecting rod 10
Drive another oil extraction of single-column plug cylinder 3.By the stroke ratio specially designed, i.e. cylinder body 1 comes and goes twice, oval cam 4
Just rotate a circle, so as to drive two pulverizer operatings simultaneously, improve operating efficiency.Hydraulic cylinder horsepower is big simultaneously, torque
Greatly, card machine, the phenomenon to crash are not easily caused, and many troubles are alleviated to operating personnel.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
