Abstract

In the existing hammer crusher, the hammer rotates and continuously crushes and pulverizes the input aggregate. When the aggregate is continuously hit, the wear and damage of the part where the impact is concentrated on the hammer progresses rapidly, resulting in a short lifespan, and not only the hammer In addition, the inner surface frame of the inlet of the hammer crusher device is also severely damaged, and only the worn part cannot be replaced separately, so the overall life span is short, and it is difficult to crush the size of aggregate discharged after being crushed to a size suitable for the user's use. Since the size of the aggregate cannot be adjusted, the difference in size of the crushed aggregate is large and the quality of the aggregate deteriorates. Consisting of an aggregate crushing housing 100, a crushing hammer unit 200, and a rotational power unit 300, the hammer continuously strikes the aggregate and the impact and friction of the aggregate intensively occurs during crushing and the inner surface of the hammer crusher device. Damaged parts can be partially replaced during wear and tear, and overloading of the hammer crusher device can be prevented by preventing excessive input of aggregate in an instant. The purpose is to control the size of the aggregates to be crushed and discharged by adjusting the spaced interval, and to quickly respond to situations such as equipment malfunction and emergency situations by providing operation information of the hammer crusher device to the operator.

In addition, it is possible to improve the lifespan of the crushing hammer by preventing abrasion and damage of the rear inclined surface of the upper V-groove and the rear surface of the upper end of the third hammer body.

As such, the third hammer body 243a according to the present invention is stably fastened by combining the front reinforcement frame 243b and the rear upper reinforcement frame 243c through welding or bolting, and debonding is difficult when bolts are fastened. It has the advantage of being easy, and the bolt to be fastened is inserted into one side of the rear side of the top and coupled, and the head of the bolt uses a flat head bolt that does not protrude to the outside, minimizing the direct contact of the bolt with the aggregate when crushing the aggregate, so that the bolt head damage can be prevented.

Through this, the crushing hammer rotates and minimizes wear and damage to the front and top front, top V-groove, and top rear of the hammer head, where external force is concentrated by direct impact during aggregate crushing, and even if wear and damage occurs, only a portion of Since it can be replaced, replacement costs due to maintenance and repair can be minimized.

In addition, the third hammer body 243a has a V-groove on the upper end of the third crushing hammer 243 through the first inclined surface 243b-2 and the second inclined surface 243c-1 that contact and protect the upper V-groove. form

Through this, not only the first blow of the aggregate by the rotation of the third crushing hammer, but also the second blow of the aggregate is applied to the V-groove formed on the upper surface of the first crushing hammer, and the third crushing hammer rotates in the lower direction. Aggregate is brought into the V-groove and frictional impact is applied to improve aggregate crushing efficiency.

In addition, the third crushing hammer 243 according to the present invention may be formed by replacing the front and rear top reinforcement frames on the surface of the third hammer body with wear-resistant welding rods, respectively, by build-up welding.

This is an abrasion-resistant welding rod that welds the front, top V-groove, and top surface of the third hammer body as a whole to prevent the surface of the third hammer body from being exposed to the part that directly hits the aggregate, thereby fundamentally blocking wear and damage. As long as the third hammer body is not directly damaged, there is no need to replace it, so the lifespan can be greatly improved.

Next, the rotational power unit 300 according to the present invention will be described.

The rotary power unit 300 is symmetrically coupled to the left and right ends of the crushing hammer unit passing through the center of the aggregate crushing housing, and is connected to a drive motor in a belt structure to transmit driving force to the crushing hammer unit.

Here, the belt that transmits the driving force of the rotary power unit 300 may have a V-belt or timing belt structure.

In addition, the hammer crusher device 1 according to the present invention is installed on one side of the aggregate crushing housing, is connected to the user's smart terminal through a network, receives real-time detection information of the aggregate crushing housing inside the smart terminal, and monitors management information. It includes a smart control unit 400 that transmits a notification message in case of malfunction or emergency and performs integrated remote control.

The smart control unit 400 according to the present invention is connected to the hammer crusher device through a network to control the aggregate crushing housing, the crushing hammer unit, and the rotational power unit in real time, and converts the aggregate crushing input amount and crushing discharge information data per hour of the aggregate crushing housing into time, It stores period-specific information such as date, detects abnormal operation of the aggregate crushing housing, crushing hammer unit, and rotary power unit, and sends a notification message.

At this time, by detecting the load current in the motor of the rotational power unit, when the load current within the standard range is detected, the aggregate input is continuously performed as much as the preset input amount, and when the load current exceeding the standard range is detected, a notification message is sent to the user's smart terminal. It automatically reduces the input amount of aggregate to prevent overload, thereby preventing breakdown and damage of internal devices.

Hereinafter, the operation process of the hammer crusher device having excellent crushing efficiency and easy maintenance according to the present invention will be described.

First, the front fastening frame and the rear fastening frame, which are shaft-coupled to the aggregate crushing housing, are rotated in an outward direction relative to an axis to open them.

Next, the shock plate is sequentially inserted and filled in a lattice arrangement in a sliding structure inside the front inlet frame of the front fastening frame, and the separation prevention fastening frame is coupled and fixed to the lower end.

Next, the shock plate is sequentially inserted and filled in a lattice arrangement in a sliding structure inside the rear inlet frame of the rear fastening frame, and the separation prevention fastening frame is coupled and fixed to the lower end.

Next, a plurality of crushing hammers coupled to the crushing hammer unit are selectively coupled among the first crushing hammer, the second crushing hammer, and the third crushing hammer.

Here, the first crushing hammer is coupled to the first hammer body by bolting the front reinforcement frame and the rear top reinforcement frame made of steel casting material, or the front reinforcement frame and the rear top reinforcement frame to the surface of the first hammer body It is formed by replacing each of the build-up welding with a wear-resistant welding rod.

Here, the second crushing hammer is coupled to the second hammer body by welding or bolting a right angle reinforcement frame made of steel casting, or replacing the right angle reinforcement frame to the surface of the second hammer body by build welding with a wear-resistant welding rod is formed by

Here, the third crushing hammer is coupled to the third hammer body by welding or bolting the front reinforcement frame and the rear top reinforcement frame made of cast steel material, or the front reinforcement frame and the rear surface of the third hammer body It is formed by replacing the upper backing frame with a wear-resistant welding rod, respectively, by build-up welding.

Next, the front fastening frame and the rear fastening frame are rotated inward with respect to the axis to close them.

Next, the gap between the gap adjustment plate and the crushing hammer is finely adjusted by moving the gap adjustment cylinder forward and backward according to the required crushing size of the aggregate.

Finally, the aggregate to be crushed is put into the hammer crusher device to start the crushing of the aggregate, and the smart controller continuously monitors and controls it.
