Mobile brand

Technical field

The present invention relates to a mobile plant capable of satisfying the specifications of a vehicle capable of traveling on public roads, and more particularly, to industrial raw materials such as coke, construction waste materials, and various waste materials such as bottles and cans. And a mobile brand for crushing or sieving various objects to be treated. Background art

In mines or manufacturing plants where various industrial raw materials such as coke, ferro-alloy, iron ore, and phosphate rock are generated, these industrial raw materials are crushed from large lump and shipped by truck or rail to ports or direct demand. Send it out. The crushing in this case is generally crushing below the maximum particle size suitable for transportation, and the particle size distribution of the crushed industrial raw material ranges from fine powder to the above-mentioned mass of the maximum particle size. It does not match the particle size distribution required by customers. In addition, the crushed industrial raw material is subjected to various handlings and transported before being put into final demand equipment such as a blast furnace and a blast furnace, and is damaged during the process to receive fine powder and fine powder. Grains increase, and foreign materials such as stones and wood chips are mixed. Therefore, somewhere between the transportation by ship or truck and the loading / unloading at storage yards and before entering the final demand equipment, the particle size distribution of these industrial raw materials conforms to the particle size distribution range required by the customer. Where there was a requirement for secondary crushing and sieving work equipment.

In addition, in the transportation of granular cargo of agricultural products such as grains such as wheat and rice, the number of broken grains and powder increases and the inclusion of foreign matter during repeated handling is eliminated. Sieving work is sometimes required.

In addition, when disposing of foods and beverages, drugs, and other bottled or canned products with the contents still contained in these containers, the containers should be crushed and collected separately from the contents. Has been done.

Conventionally, for these crushing and sieving, dedicated crushing machines and The sieving machines are permanently installed and used as fixed facilities in factories and the like that are required respectively, and are also used for coarse crushing and intermediate crushing or fine crushing, or coarse sieving and intermediate particle size sieving or fine powder sieving. In fact, each of them has a dedicated machine. An example of the particle size distribution required by the consumer is the case of coke, which is most suitable for blast furnace coke to maintain appropriate voids in the blast furnace and to function as a heat source and reducing agent. The average particle size is about 20 to 50 mm.On the other hand, in the case of a ferrous coke, the air volume per cubic cross-sectional area is larger than that of a blast furnace, and the air gap maintenance, heating, The optimum particle size to function as a carbon material is larger than the blast furnace coax, and is selected to be about 1/8 to 1/12 of the inner diameter of the cuvola, specifically, about 60 to 80ππη, 80 to 120 bandages, and 120 mm or more. Such various particle sizes are required. In addition, ferrous iron coke used as a resistance heating and reducing material in electric furnaces for the production of ferroalloys such as ferromanganese or fluorochrome uses particles with a particle size of 10 to 3 Omm, and carbon such as coal. Coke gas for C0 gasification has a particle size of about 30 particles.Others have different particle sizes depending on the furnace used, such as calcium carbide, limestone firing, cement manufacturing, and heating. Is required. Conventionally, for example, ores transported on a Cox II transport ship manufactured in Cox-Sweet are put into various crushers as fixed equipment, crushed to an appropriate particle size, and then sieved. Then, the sieved product is returned to the crusher, and those with a suitable particle size range are collected by a belt conveyor or the like. The collected coke of the applicable particle size range is transported by truck, etc., and after calibration, stored in a sorting warehouse in the factory. From there, they are delivered directly to customers by truck, or transshipped to carriers and delivered to customers by truck transport.

Conventional crushers and sieving machines are fixedly installed in the workplace.As described above, it is necessary to have multiple crushers and sieving machines dedicated to specific objects to be treated. Needed a permanent space.

In addition, conventional crushing machines and sieving machines are dedicated machines in which the objects to be processed and the contents of the processing are individually and fixedly determined, so that various objects are crushed or separated into various particle sizes. Needed to have many dedicated machines. In other words, these dedicated machines For example, in the case of a single crusher, the crushing capacity is fixedly determined, and in the case of a vibrating sieve, the area is fixedly determined. On the other hand, the properties of the object to be treated vary widely depending on the type, and the properties of the object differ not only depending on the size, shape, specific gravity, viscosity, agglomeration due to moisture and icing, etc. Even for items, they differ depending on the environmental conditions (weather, humidity, etc.) at the storage site. For example, in the case of a vibrating sieve, in order to improve the sieving quality when the sieving area is fixed, the residence time of the object to be treated on the sieve mesh surface is lengthened, and conversely, the sieving work efficiency is improved. For this purpose, there is a conflicting demand to shorten the residence time on the sieve screen, and as a compromise between these requirements, the optimal conditions must be selected according to the properties of the object to be treated and the on-site environmental conditions. Furthermore, in conventional crushers and vibrating sieves, the position where the object to be treated is put in and the position where the processed product is taken out are fixed in a fixed positional relationship. However, there was a problem that it was not always possible to obtain the optimal working position for the positional relationship between the two.

-Disclosure of the invention

The present invention has been made in view of the circumstances described above, and can crush or separate an object to be treated at any time in a production area, an accumulation area, or a consumption area, and The main purpose of the present invention is to provide a multipurpose mobile brand for a variety of products that can flexibly cope with a positional relationship between an accumulation position of an object and a removal position of a processed product.

According to the present invention, the above objects are solved by a mobile brand having the features stated in the claims.

That is, the mobile brand according to the basic aspect of the present invention has an upper surface opening mounted on a front portion on a movable vehicle chassis for receiving an object to be processed and an outlet facing the rear side of the vehicle chassis. A receiving hopper, feeder means for sending out an object to be processed in the hopper from the outlet, and an object to be processed sent from the hopper outlet by the feeder means toward the rear of the chassis.撟手段で撟撟撟撟撟撟撟撟撟撟撟撟撟撟撟撟撟撟撟撟撟撟手段手段を受けを受け撟を受け撟撟撟撟手段手段を受けA working machine mounted on the rear part of the chassis to apply required physical processing operations such as to the object to be processed; and Serial comprises an outlet conveyor hand stage for feeding the object to be processed to the outside of the vehicle chassis, and a speed control means for variably adjusting the speed of the Fi Ichida means and the bridging conveyor means.

In a mobile brand according to a preferred aspect of the present invention, the speed control means includes a controller for controlling the speed of the outlet conveyor means in proportion to the speed of the bridging conveyor means.

Further, in a mobile brand according to another preferred aspect of the present invention, the vehicle chassis is constituted by a semi-trailer towed by a tractor, and the semi-trailer includes substantially front end portions, substantially rear end portions on both left and right sides of the chassis, and an intermediate portion therebetween. At least one part of the vehicle is equipped with a jacking means for supporting the vehicle load during the work with respect to the ground, and the jacking means at the front end can be retracted or removed so as not to interfere with the tractor when the tractor is connected. Things.

A work machine such as a crusher machine or a vibrating sieve machine vibrates on the semi-trainer. It is installed as a motion source, and the vibration generated during work may propagate through a relatively long chassis and generate large vibrations in unexpected parts. In a normal semi-trailer, the gooseneck in front of the semitrailer is freely connected to the tractor, and a fixed projection structure is provided on the underside of the gooseneck to avoid mutual mechanical interference during running. Nothing is provided.

On the other hand, in the semitrailer of the present invention, the jack means are provided on both the left and right sides at several points at the front end, the rear end, and the intermediate part thereof, and these jack means are crushed. In this case, the vehicle load is supported by stretching against the ground, thereby preventing the occurrence of excessive vibration over the entire length of the chassis. Particularly, the jack means at the front end is provided so as to be retractable or removable to an appropriate retreat position which does not mechanically interfere with the tractor when the semi-trailer is connected to the tractor and travels. The evacuation position can take various forms, such as holding the jack cylinder sideways along the side of the gooseneck portion of the semirailer or standing up above the gooseneck portion.

In a mobile brand according to still another preferred embodiment of the present invention, a gate for variably adjusting the size of the outlet opening is provided at the outlet of the hopper. In a mobile brand according to still another preferred aspect of the present invention, the work machine is mounted so as to be replaceable from the rear of the chassis.

Further, in a mobile brand according to still another preferred embodiment of the present invention, the bridging conveyor means includes an inclination angle adjusting means for changing a height of a rear end thereof.

Further, in a mobile brand according to still another preferred aspect of the present invention, the outlet conveyor means includes a rear discharge conveyor extending in a vehicle length direction below the work implement.

In a mobile brand according to still another preferred embodiment of the present invention, a crusher machine is mounted as the working machine. As this crusher machine, for example, a jaw crusher, a single or double roll crusher can be selected according to the application. In a mobile brand according to still another preferred embodiment of the present invention, a vibrating screen machine is mounted as the working machine. In this case, the vibrating sieve comprises a first outlet for discharging the object having a relatively large particle size remaining on the sieve mesh toward the front of the chassis, and a first outlet for discharging the lower portion from the sieve mesh. A second outlet for discharging the object having a small target particle size to the lower side of the vibrating sieve, wherein the outlet conveyor means comprises a first outlet on the chassis at a position forward of the vibrating sieve. A widthwise discharge belt conveyor for feeding the object from an outlet in a chassis width direction; and a vehicle length direction for sending the object from the second outlet to a rear of the chassis at a lower portion of the vibrating sieve. And a discharge belt conveyor. Further, the vibrating sieve may include a plurality of sieve screens arranged vertically, and in this case, the first outlets are provided in plurality corresponding to the number of sieve screens, and thus the widthwise discharge is performed. A plurality of belt conveyors are also installed in parallel. The widthwise discharge belt conveyor can send out an object in either the left or right direction of the chassis by reversing the driving direction of the compare belt.

In the rear part of the vehicle chassis, the vibrating sieve receives the object falling from the bridging conveyor means at an upper rear end thereof and flows downward on a sieve net in a forwardly inclined posture. The sieving is performed together with the vibration while the sifting is being performed. Have been. The vibration of the screen of the vibrating sieve is given by an eccentric rotational movement about the axis in the width direction of the vehicle chassis, and the rotational direction of the eccentric rotation can be reversed. That is, when a forward eccentric rotation is given to the flow direction of the object on the screen, the object flows down on the screen at a relatively high speed. When the eccentric rotation is given in the direction opposite to the flowing direction, the object flows down the sieve at a relatively low speed, thereby enabling the separation efficiency to be changed. Of course, if this is combined with the variable adjustment of the frequency, it is possible to further finely adjust the separation efficiency. Therefore, the vibrating machine has at least a sieve, an inclination angle, and a frequency so that work using the entire surface of the vibrating surface of the vibrating machine can be performed according to the properties of the object to be treated and the working environment conditions. , Either of the vibration tilt direction can be changed. The object to be processed is supplied by a variable speed feeder and a variable speed conveyor in accordance with the adjusted throughput of the vibrating sieve described above, and is processed without delay. For this reason, the optimum sieving speed and efficiency can always be selected. .

More preferably, the vibrating sieving machine is provided at its rear end with a receiving plate for receiving an object to be processed dropped and supplied from the bridging conveyor means, and between the receiving plate and the sieve mesh.

A weir plate extending in the width direction protrudes from the Z or sieve mesh. The receiving plate and the weir plate are for allowing the falling object to flow down widely on the screen surface of the sieve, thereby effectively utilizing the entire surface of the screen of the vibrating screen. Thus, the sieving efficiency and the sieving throughput can be improved. Also preferably, by utilizing the fact that the gap between the tip of the bridging conveyor means and the receiving plate changes due to the vibration caused by the operation of the vibrating sieving machine, the object to be treated blocked by the weir plate is removed. In order to crush, a hoe member protruding toward the lower receiving plate may be fixed to an end of the bridging conveyor means, so that a large lump of the object to be processed is crushed on the receiving plate. It can be made to flow down on the sieve mesh surface. For example, even if the object to be treated is clumped due to moisture or icing, the hoe member breaks it, so that a large lump does not ride on the sieve mesh surface. If there is a possibility that a huge lump that cannot be crushed by the hoe member may fall from the bridging conveyor means, attach a grizzly with an appropriate gap to the rear end of the bridging conveyor means, and The lump may roll as it is on a shot outside the vehicle.

Since the mobile brand according to the present invention is mounted on a vehicle chassis in which all elements can travel, the mobile brand moves to a site where objects to be processed that need to be crushed or separated are accumulated and goes to the site All processing operations can be performed. For example, coal, coke, ferro-alloy, pig iron slag, etc. are piled up and stored in a yard, or various construction wastes and food and drink wastes are accumulated in a predetermined place. The mobile brand according to the present invention is capable of carrying out the processing work by going to the side of the mountain of the object to be processed at these yards ゃ accumulation site, and furthermore, to adjust the feeder means and the bridging conveyor means at a variable speed. Therefore, the processing conditions such as the speed and efficiency of crushing or sieving for various objects with different particle size distributions and densities were changed. It is possible to individually perform the processing work with the optimum efficiency of the working machine.

In the mobile brand of the present invention, an object to be processed is put into a hopper in front of a chassis by a bucket crane, a hydraulic excavator, or the like, and is fed from a feeder at an outlet of the hopper through a gate adjusted to an appropriate opening size. The objects are discharged on the conveyer in a fixed amount. In this case, a structure should be adopted in which water from the hopper outlet to an appropriate position on the bridging conveyor is sprayed from the nozzle with humidity control spray water or dust-prevention spray water to improve work efficiency. Is desirable. By spraying spray water into the gap between the hopper outlet and the bridging conveyor means from the front of the chassis to the rear, the object to be treated that falls from the hopper outlet onto the bridging conveyor means and the conveyor of the bridging conveyor means Both the surface and the surface can be humidified, and the object to be treated on the surface of the bridging conveyor means can be further humidified by sprinkling water from above.

The bridging conveyor is attached to the middle of the chassis at an upward slope toward the rear, and the rear end of the bridging conveyor is located at the top of the upward slope. Below the rear end of the bridging conveyor, a work machine that receives the object to be processed falling from it and crushes or sieves is mounted on the rear part of the chassis. The arrangement of hoppers, handover conveyors and work implements on the chassis is effective in minimizing the height and length of the chassis, thereby ensuring that the overall dimensions are regulated by the Vehicle Law. It can fit within the legal limits for running vehicles.

In the mobile brand of the present invention, the hopper and the working machine are arranged separately on the front and rear of the chassis, and the hopper and the working machine are connected to each other by a bridging conveyor arranged in an inclined manner. The object to be treated discharged at the above can be fed into the working machine at a desired set speed by a bridging conveyor. In particular, in the mobile brand according to the present invention, both the feeder and the bridging conveyor are of a variable speed type in which the speed is adjusted by speed control means, and the size of the opening is provided at the hopper outlet. Since a variable adjustment gate is provided, for example, by driving the bridge conveyor at a relatively high speed, a certain size of the material discharged from the hopper by the feeder via the gate is fed. Relatively little time to process objects Injecting into the working machine at a constant flow rate, or conversely, driving the bridging conveyer at a relatively low speed, the workpiece to be discharged from the hopper by the feeder at a constant rate is thrown into the working machine at a relatively large flow rate per hour. Can be. On the working machine side, for example, in the case of a single crusher, the crushing characteristics can be changed by changing the crushing gap and speed of the crusher blade and roll.In the case of a vibrating sieving machine, the mesh size of the sieving mesh and the frequency and frequency can be changed. Since the sieve characteristics can be changed by changing the rotation direction, the specific gravity and target particle size, for example, according to various properties of the object to be treated and the target product, such as specific gravity and hardness, target product particle size and moisture content, etc. Large-sized or low-hardness objects are sent in large quantities to perform work efficiently, and small-specific-density or target-particle-size or high-hardness objects are sent at a small flow rate to prevent overloading of the work equipment. For example, it is possible to selectively set the optimal work according to the machine strength and processing capacity of the work machine.

The working machine such as the crusher or the vibrating sieve machine may be an on-board working machine with a slight improvement of a normal fixed installation type working machine.In the mobile brand according to the present invention, this working machine can be replaced from the rear of the chassis. In order to maintain the work equipment or vehicle chassis, the work equipment can be exchanged or the work equipment on the chassis can be replaced with a different work equipment according to the work target. This allows the healthy chassis or working machine to be operated without play, and maintenance work for both can be carried out at their specialized factories.

When a jaw crusher is installed as the crusher machine, this is applicable to a wide range of materials from medium hardness materials such as coal and coke to carbide materials such as titanium ore, and crushing these crushed materials to a uniform size. It is suitable for.

When a crusher machine is equipped with a sindal roll crusher, it is most suitable for crushing soft and medium-soft materials, and crushes these crushed materials into a uniform size with relatively few fine powders.

Furthermore, when a double roll crusher is installed as one of the crushers, it is most suitable for crushing soft and medium soft raw materials and secondary or tertiary crushing of hard raw materials, and crushes the material to be crushed into uniform small powder. It is also suitable for According to the mobile brand of the present invention, since the work can be performed while going to the accumulation area of the object to be processed, the transportation process in the object to be processed can be omitted, and in this case, the bridging conveyer and the working machine are used. In addition to this, inconvenient foreign matter such as metal articles and wood debris can be easily removed in front of the work machine by using a magnetic separator or manual work of workers as necessary. By preparing the required number of semi-trailers equipped with different types of work equipment according to the work contents at the site and going out, it is possible to configure a work equipment group with an optimal arrangement even without any work equipment, and to perform some work Even where equipment is present, it is possible to compose a set of working machines that complements the lack of functions. In addition, it must be possible to cope with a wide variety of objects to be processed in the point that it is a mobile type. It is possible to work under the optimum working conditions according to the properties of the object.

The above and other features and advantages of the present invention will become more apparent from the non-limiting examples described below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE FIGURES

In the first embodiment shown in FIG. 1, a towing I vehicle, that is, a tractor 300 This is an example of a mobile brand where a crusher is mounted on a semi-trailer towing and traveling.

In Fig. 1, a receiving hopper 14 whose upper side wall can be folded by a hinge 12 is mounted on the front of the chassis 10 and a single roll crusher machine 16 is mounted on the rear. A belt conveyor 22 for bridging feed connects between the hopper exit 18 facing the rear of the vehicle and the loading section 20 at the top of the crusher machine 16 toward the rear in the middle of the chassis. It is provided with an upward slope. E, Sopa 14 is provided with a plate feeder 24 reciprocating in the vehicle length direction on the bottom surface of the rear exit 18. The opening of the hopper outlet at the distal end of the feeder 24 may be, for example, a fixed opening. In this example, a variable opening gate 26 that is opened and closed by operating a handle is provided. The belt conveyor for feeding 22 can be lifted up with its front part as a fulcrum, and is held at the height connected to the loading section 20 as shown in Fig. 1 during normal times (during running or working), and is cleaned. · During maintenance or changing the setting of the crushing gap, etc. (1) When the crusher machine 16 is replaced, the crusher is raised to a predetermined height so that it can be evacuated from above the crusher machine 16.

The rear lower part of the belt conveyor 2 2 is a space for placing one crusher 16. This crusher 16 is a single motor-driven type single crusher with adjustable rotation speed. It is replaced from the rear of the chassis. It is mounted by a slide rail mechanism (not shown) with a lock so that it can be used. Crusher machine 16 Accepts the material to be crushed from the input section 20 at the top, and discharges the crushed product from the discharge port 28 at the bottom. At the lower part of the crusher machine 16 is mounted a discharge belt conveyor 30 for receiving the crushed product discharged from the bottom discharge port 28 of the crusher machine 16 and sending it to the rear of the chassis.

At the lower part of the belt conveyor 22 at the front of the crusher 16, the lower surface of the chassis is located at the lower end of the feed belt conveyor 22 and at the lower end of the outlet rod of the hopper 14. Nozzles 32 and 34 for sprinkling water toward the surface are provided with water tanks 36 connected via bombs (not shown), and the belt surface is moistened with water from these nozzles 32 and 34. And adjusting the moisture content of the crushed material, Prevention of dust generation and improvement of breakage can be selectively achieved.

The driving of the on-board equipment for crushing, such as the feeder 24, each belt conveyor 22 and 30, the crusher machine 16, and the water supply pump to the nozzles 32 and 34, is performed at the front end of the chassis 10. Power is supplied from the generator 38 mounted in the section (the gooseneck). The generator 38 is provided with a speed control device 39 for controlling the speed of the feeder 24 and the belt conveyor 22. The speed control device 39 controls the belt in proportion to the speed of the belt conveyor 22. It includes a controller 39a for controlling the speed of the conveyor 28. In addition, these operation control and control such as speed

It can be operated from around 38 or from the operation panel of the vehicle.

In FIG. 1, reference numerals 40, 42, 44, and 46 denote jacks provided on the left and right sides of the chassis 10. These jacks are reduced during traveling and maintain the ice stability of the vehicle body during work. Therefore, each is extended to support the full load of the vehicle. These jacks may be of the manually operated mechanical or hydraulic type, and are preferably such that each can be adjusted independently. The jack 40 at the front end and the jack 46 at the rear end are important for the horizontal stability of the vehicle body, and the jacks 42, 44 at the middle are chassis 10 together with the jacks 40, 46. It is important to prevent excessive vibration of the vehicle. In this example, two pairs of jacks are used as jacks in the middle.

Although 42 and 44 are provided, this may be one pair or three or more pairs in some cases.

Of the jacks, the jack 40 at the front end in particular can be retracted sideways along the side of the relatively narrowed neck portion 10a at the front of the chassis 10 as shown. After the tractor 300 is separated from the trailer 110 during work, the jack 40 is raised and extended. The evacuation posture of the jack 40 is not limited to the example shown in the figure, and for example, the front edge of the gooseneck portion 10a may be arranged along the vehicle width direction, or may be turned upside down, or may be detached from the chassis. You may put them in the right place at 10.

By the way, the mobile brand of this embodiment travels on a public road to a destination by a towing I vehicle 300 and is parked beside the crushed material piled up at a work site. The The body is stably held horizontally by the jackets 40, 42, 44, and 46, and a transfer belt conveyor (not shown) is connected downstream of the discharge belt conveyor 30 as necessary to prepare for work. . The material to be crushed is put into the hopper 14 in the front part of the chassis by a shovel or another belt conveyor from the pile, but in this case, the hopper side wall on the input side is folded by the hinge 12 and the other side walls are If it is kept upright, it is not necessary to raise the lifting height of the power shovel, etc., and the crushed material input from the shovel, etc. when closing the hopper is closed. This is convenient because it does not fall outside due to the presence of the side wall.

When the gate 26 is set to an appropriate opening size, the larger crushed material remains there and is not thrown into the crusher machine 16, so that no crusher is destroyed. . When the material to be crushed is put into the hopper 14 with the feeder 24, the belt conveyors 22, 28, and the crusher machine 16 started at the predetermined set speeds, the feeder 24 feeds the crushed material from the hopper outlet at a constant rate. The crushed material reaches the upper charging section 20 of the crusher machine 16 by ascending by the belt conveyor 22 and is then charged into the crusher machine 16 from there. In this case, it is preferable to set the speed of the belt conveyor 22 so that the crushed material does not stay in the charging section 20 of the crusher 16. The crusher machine 16 crushes the object to be crushed while rotating downward by the rotation of the motor, and the crushing gap and the rotation speed in this case are set to desired values in advance. When the water content of the material to be crushed is low, the water in the water tank 36 is adjusted by spraying water from the nozzles 32 and 34 to prevent dust generation and ensure the crushing performance of the crusher machine 16. And to do.

The crushed product crushed by the crusher machine 16 is discharged from the bottom discharge port 30 onto a discharge belt conveyor 28. The discharge belt conveyor 28 is driven at a speed proportional to the speed of the belt conveyor 22, so that the crushed products received by the discharge belt conveyor 28 conform to the processing speed of the crusher machine 16. At the specified speed, it is sent to the rear of the chassis and transferred to a collection location at a desired position or a direct transport vehicle by a transfer conveyor or the like (not shown).

The mobile plant in this example uses coal, coke, It can be used for crushing various objects such as gold and iron, various ores, various construction waste materials such as roads and buildings, food and beverages to be disposed of in bottles and cans, medicines, cosmetics, and detergents. In such a case, it is possible to change the crusher machine according to the target object, or prepare the same number of work vehicles equipped with one type of crusher, and then go to the location where the target crushed materials are collected and work. For example, when crushing bottles or cans containing liquid contents, carry a rubber mat with an area that can accommodate the chassis 10 of the semi-trailer, spread the rubber and jito on the work ground, and ride the chassis 10 on it Cut off the tractor 300 and raise the area around the rubber mat with a log or other material to make it a boule shape before crushing. As a result, the outflow of the liquid contents caused by the crushing is stopped in the rubber mat, and the liquid contents accumulated in the rubber mat can be sucked by a vacuum car and transferred to the industrial waste treatment plant.

As described above, according to the mobile brand according to the first embodiment, the entire configuration can be combined as traveling vehicles on public roads without making the overall configuration excessively large, and play an important role in various industrial fields. Occupation of crushed materials such as ore and other industrial wastes can be efficiently crushed by going to the production area, accumulation area, or consumption area. As the number of times of handling of the crushed material is reduced, chances of foreign matter mixing are reduced. In addition, jacks are provided at the front and rear ends of the chassis and in the middle of the chassis to ensure horizontal stability during work and prevent excessive vibration from occurring. The intermediary of the conveyor for feeding facilitates the removal of foreign matter, and the speed of this conveyor is variably adjusted along with the feeder speed of the hopper and the number of revolutions of the crusher machine, and the load during work is adjusted.
