Generally, the hopper is located at the top of the machine. Therefore, for example, when operating a backhoe to supply crushing objects to a hopper, the hopper may be located at a higher position than the backhoe driver.

When the hopper is located higher than the driver, the driver often cannot visually see the opening above the hopper. Furthermore, since the driver's upward view is likely to be obstructed by the hopper, it is difficult to visually recognize the bucket at a high position. Therefore, it is easy for the driver to make a mistake in operation, and for example, the bucket or hopper may be damaged due to contact between the bucket and the hopper. On the other hand, when working with the bucket placed at a sufficiently high position relative to the hopper so that the bucket and hopper do not come into contact with each other, there is a possibility that the hopper may be damaged by the impact of falling raw materials.

Furthermore, since it is difficult for the driver to understand the depth of the hopper, it is difficult to position the bucket, and raw materials may spill from the hopper due to incorrect bucket operation.

The present invention has been made in view of the above circumstances, and its purpose is to enable accurate loading work even when loading objects into the hopper from a low position in a mobile processing machine equipped with a hopper. It is in.

The problem to be solved by the present invention is as described above, and next, the means for solving this problem and the effects thereof will be explained.

According to the aspect of the present invention, a mobile processing machine having the following configuration is provided. That is, this mobile processing machine is provided with a traveling device and a hopper for charging objects. The mobile processing machine processes the object put into the hopper. The mobile processing machine includes a pole that protrudes upward from an inner wall of the hopper. The height of the upper end of the pole is higher than the upper end of the hopper.

Thereby, even if the hopper is located at a higher position than the operator, the operator can use the pole as a landmark to accurately grasp the positional relationship of objects above the hopper with respect to the hopper. Therefore, for example, when putting an object into a hopper with a working machine, it is possible to perform the work by accurately determining the position of the working part of the working machine. Therefore, contact between the hopper and the working part can be prevented. Furthermore, it is possible to prevent damage to the hopper or the like due to objects falling from the working section located at a too high position.

In the mobile processing machine described above, it is preferable that the pole is elastically deformed.

Thereby, it is possible to reduce the impact when the working part or the like collides with the pole of the working machine, and it is possible to reduce damage to the working part.

Thereby, the pole can be removed together with the protection member, and the pole can be easily replaced.

The mobile processing machine described above preferably has the following configuration. That is, a plurality of the poles are provided. The plurality of poles include a pole whose color is different from other poles.

Thereby, for example, by changing the color of the pole depending on the installation location, it becomes easier for the operator to confirm where in the hopper he is working.

In the mobile processing machine described above, it is preferable that the pole is replaceable.

As a result, even if the pole is damaged, by replacing it with a new one, the worker can once again obtain a landmark for reference.

In the mobile processing machine described above, it is preferable that the pole is provided with a reflective material.

This makes it possible to make the pole stand out and easily use it as a landmark even when visibility is poor.

Preferably, the mobile processor is configured as a crusher or a sorter.

Thereby, it is possible to provide a crusher or a sorter that can accurately load objects to be crushed or sorted into a hopper.

Preferably, the mobile processor is configured as a mobile crusher or a mobile sorter.

Thereby, even if the position of the hopper changes together with the mobile crusher or the mobile sorter, the work of charging the hopper into the hopper can be performed stably and accurately.

According to the present invention, in a mobile processing machine equipped with a hopper, even when an object is charged into the hopper from a low position, the charging operation can be performed accurately.

1 is a side view showing the overall configuration of a mobile crusher according to an embodiment of the present invention. FIG. 2 is a perspective view showing a hopper and a feeder. The figure which shows how the object to be crushed is put into a hopper using a backhoe.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing the overall configuration of a mobile crusher 100 according to an embodiment of the present invention. FIG. 2 is a perspective view showing the hopper 11a and the vibratory feeder 11b. FIG. 3 is a diagram showing how objects to be crushed are put into the hopper 11a using the backhoe 101.

A mobile crusher 100 (mobile processor) shown in FIG. 1 is used, for example, to primarily crush raw stones (objects to be crushed, objects) such as aggregates and limestone.

The mobile crusher 100 is configured as a self-propelled crusher in which the crushing equipment 1 is mounted on a traveling device 2. The mobile crusher 100 includes an engine (not shown) as a main driving source, and a generator 4 for supplying electric power to the crushing equipment 1.

The traveling device 2 can move the mobile crusher 100. The traveling device 2 is arranged below the crushing equipment 1. The traveling device 2 includes a crawler 2a and a sprocket 2b.

The crawler 2a is formed into an endless shape made of, for example, a steel plate, and is wound around the sprocket 2b. The sprocket 2b is connected to an output shaft (not shown) and rotates as the output shaft rotates. By rotating the left and right crawlers 2a in the same direction at the same speed, the mobile crusher 100 can be moved straight. Hereinafter, the direction in which the mobile crusher 100 moves straight in this manner may be referred to as the front-rear direction, and the direction perpendicular to both the front-rear direction and the up-down direction may be referred to as the left-right direction.

The crushing equipment 1 is configured, for example, as a primary crushing equipment that roughly crushes an object to be crushed, such as raw stone mined at a rock mining site. This crushing equipment 1 includes a crushing object supply device 11, a crushing device 12, a crushed material discharge conveyor 13, and a plurality of electric motors (not shown).

The crushing object supply device 11 transports the crushing object fed by the working machine to the crushing device 12 . The crushing object supply device 11 is provided on one side of the mobile crusher 100 in the front-rear direction. The detailed configuration of the crushing object supply device 11 will be described later.

The crushing device 12 crushes the object to be crushed that is supplied by the object to be crushed supplying device 11 . The crushing device 12 is configured, for example, as a single toggle type jaw crusher (oscillating type crusher) including fixed teeth 12a and movable teeth 12b shown in FIG. The fixed teeth 12a are fixedly provided to the crushing equipment 1. The movable teeth 12b are provided so as to be slidable relative to the fixed teeth 12a, and are driven by an electric motor. The crushing device 12 crushes the object to be crushed that is placed between the fixed teeth 12a and the movable teeth 12b by sliding the movable teeth 12b.

However, the crushing device 12 may be configured as, for example, a known cone crusher (rotating type crusher) or an impact crusher (collision type crusher).

The crushed material discharge conveyor 13 discharges the crushed materials crushed by the crushing device 12 to the outside. The crushed material discharge conveyor 13 is provided on the opposite side of the crushed object supply device 11 in the front-rear direction of the mobile crusher 100 . Note that the crushed material discharge conveyor 13 may be provided on the same side as the crushed object supply device 11 in the front-rear direction of the mobile crusher 100.

The crushing object supply device 11, the crushing device 12, and the crushed material discharge conveyor 13 are all driven by electric motors (not shown). However, the crushing equipment 1 may be driven, for example, by a hydraulic motor.

Next, the configuration of the crushing object supply device 11 will be explained. The crushing object supply device 11 includes a hopper 11a and a vibration feeder 11b.

The vibrating feeder 11b transports the object to be crushed in the hopper 11a to the crushing device 12. The vibration feeder 11b is configured, for example, as a vibration feeder with a grizzle. The vibrating feeder 11b is supported by the support bar 15 independently of the hopper 11a.

As shown in FIG. 2, a comb plate 16 is supported inside the vibrating feeder 11b. The tip of the comb-teeth plate 16 is formed into a comb-teeth shape. The comb plate 16 is supported by the support bar 15 via a plurality of springs 17. Therefore, the comb plate 16 can vibrate relative to the support bar 15.

The vibration feeder 11b uses vibrations generated by a vibration generator (not shown) driven by an electric motor to separate the object to be crushed into large lumps and fine particles. The large lumps on the comb plate 16 are fed to the crushing device 12. The fine particles falling from the comb plate 16 are guided to the crushed material discharge conveyor 13 via a chute (not shown). However, the vibratory feeder 11b may be configured as a vibratory feeder that does not have a sorting function.

The hopper 11a shown in FIG. 2 is used to input objects to be crushed from the outside. Hopper 11a is arranged above vibrating feeder 11b. The hopper 11a is supported on a support bar 15 via a plurality of support members 18. The hopper 11a is shaped like a funnel that opens upward. Therefore, the object to be crushed, which is placed into the hopper 11a from above, moves toward the vibrating feeder 11b due to its own weight.

A plurality of liners 19 are arranged side by side on the inner peripheral surface of the hopper 11a as inner wall protection members. The liner 19 is removably fixed using a fixing member such as a bolt. Therefore, when wear progresses due to contact with the object to be crushed, the liner 19 can be replaced. The shape of each liner 19 is the same, and the above-mentioned fixing member also has the same structure. Therefore, the position at which the liner 19 is attached can be easily changed. Similarly, a plurality of liners 19 are arranged side by side on the inner wall of the vibratory feeder 11b.

As shown in FIG. 3, objects to be crushed are loaded into the hopper 11a from above by a backhoe (work machine) 101. The backhoe 101 approaches the hopper 11a from one side in the front-rear direction or left-right direction shown in FIG. 2, and charges the object to be crushed.

A pole 23 that projects upward is provided at the end of the hopper 11a in plan view. In this embodiment, four poles 23 are provided at the four corners of the hopper 11a. The pole 23 is attached to the upper surface of the liner 19 at a predetermined position among the many liners 19 arranged on the inner wall of the hopper 11a.

The lower end of the pole 23 is located in the internal space of the hopper 11a. On the other hand, the pole 23 has an appropriate length, and the height of the upper end of the pole 23 is higher than the upper end of the hopper 11a. Therefore, the upper end of the pole 23 is located outside the hopper 11a. In other words, when considering the charging opening surface 30 that partitions the internal space and the outside of the hopper 11a, the lower end of the pole 23 is located lower than the charging opening surface 30, and the upper end thereof is higher than the charging opening surface 30. in position.

The height of the upper end of the pole 23 is preferably set so that the upper end of the pole 23 can be visually recognized when approaching the hopper 11a to some extent and looking up at the hopper 11a diagonally.

Each pole 23 is made of an elastically deformable material, such as a rubber pole used as a lane separation marker on a road. Examples of this material include, but are not limited to, urethane resin.

A reflective sheet 24, which is a reflective material, is attached to the surface of each pole 23. The reflective sheet 24 is arranged at a portion of the pole 23 that is higher than the height of the hopper 11a. As the reflective sheet 24, for example, a known retroreflective material can be used.

Pole 23 is attached to removable liner 19. Since there is no need to provide a special structure on the hopper 11a side to fix the pole 23, the structure can be simplified and can be easily applied to hoppers with existing structures. Since the liner 19 is configured to be replaceable, for example, when the pawl 23 becomes worn, the pawl 23 and the liner 19 can be easily replaced. Further, by changing the position of the liner 19, the position of the pole 23 can be changed.

In the mobile crusher 100 having this configuration, a backhoe 101 is used to load objects to be crushed into the hopper 11a. The backhoe 101 includes a bucket (working part) 101a capable of scooping/dumping operations.

As mentioned above, the hopper 11a is arranged at a high position in the mobile crusher 100. Therefore, as shown in FIG. 3, when objects to be crushed are fed into the backhoe 101 at a low position, it is difficult for the driver (operator) to see the state above the hopper 11a. In this regard, in the mobile crusher 100 of this embodiment, the position of the bucket 101a with respect to the hopper 11a can be grasped using the pole 23 as a landmark. Since the pole 23 protrudes above the height of the upper end of the hopper 11a, it is easy for the driver to visually recognize the upper end of the pole 23. Since a reflective sheet 24 is attached to the upper part of the pole 23, the pole 23 can be easily recognized even when working in a poorly lit environment or in a dusty environment.

The driver of the backhoe 101 can adjust the position, height, etc. of the bucket 101a using the upper end of the pole 23 that is visible as a mark. Since the bucket 101a can be operated while referring to a specific positional reference, the bucket 101a can be positioned as intended with respect to the hopper 11a. As a result, errors in visual measurements can be prevented, and damage caused by contact between the bucket 101a and the hopper 11a can be avoided. Further, since objects to be crushed are not dropped into the hopper 11a when the bucket 101a is too high, damage to the hopper 11a, the vibrating feeder 11b, etc. can be prevented.

The color of the pole 23 may be changed depending on the position where it is placed. In this case, the driver can easily confirm the position of each pole 23 based on the color of the pole 23.

In order to suppress the impact of falling, it is preferable that the objects to be crushed be thrown into the hopper 11a from as low a position as possible. Therefore, as shown in FIG. 3, the operator of the backhoe 101 tends to place the bucket 101a at the lowest possible position above the hopper 11a and throw in the objects to be crushed. On the other hand, the pole 23 is arranged so as to protrude upward. Therefore, it is possible that the bucket 101a comes into contact with the pole 23. In this regard, in the present embodiment, since the pole 23 is elastically deformable, the impact when the bucket 101a comes into contact with it can be satisfactorily alleviated. Therefore, damage to the bucket 101a can be prevented.

Since the pole 23 is arranged inside the bucket 101a, it is conceivable that the object to be crushed thrown in from the bucket 101a may collide with the pole 23. However, even in this case, the pole 23 can be appropriately elastically deformed to release the force. Therefore, damage to the pole 23 can be prevented.

As explained above, the mobile crusher 100 of this embodiment is provided with the hopper 11a into which objects to be crushed are input. The mobile crusher 100 includes a pole 23 that projects upward from the inner wall of the hopper 11a. The height of the upper end of the pole 23 is higher than the upper end of the hopper 11a.

Thereby, even if the hopper 11a is located at a higher position than the driver, it is possible to accurately grasp the positional relationship of objects above the hopper 11a with respect to the hopper 11a using the pole 23 as a landmark. Therefore, when loading objects to be crushed into the hopper 11a using a heavy machine such as the backhoe 101, it is possible to accurately position the bucket 101a and perform the work. Therefore, contact between the hopper 11a and the bucket 101a can be prevented. Furthermore, it is possible to prevent the objects to be crushed from falling from the bucket 101a located too high and damaging the hopper 11a and the like.

Moreover, in the mobile crusher 100 of this embodiment, the pole 23 is elastically deformed.

Thereby, the impact when the bucket 101a or the like collides with the pole 23 can be alleviated, and damage to the bucket 101a can be reduced.

Moreover, the mobile crusher 100 of the present embodiment includes a plurality of liners 19 arranged side by side on the inner wall of the hopper 11a. Pole 23 is fixed to liner 19.

Thereby, the pole 23 can be removed together with the liner 19, and the pole 23 can be easily replaced.

Moreover, in the mobile crusher 100 of this embodiment, a plurality of poles 23 are provided. The plurality of poles 23 include a pole 23 whose color is different from other poles 23.

Thereby, for example, by changing the color of the pole 23 depending on the installation location, it becomes easier for the driver to confirm where in the hopper 11a he is working.

Furthermore, in the mobile crusher 100 of this embodiment, the pole 23 is replaceable.

Thereby, even if the pole 23 is damaged, by replacing it, the driver can once again obtain a landmark for reference.

Furthermore, in the mobile crusher 100 of this embodiment, a reflective sheet 24 is provided on the pole 23.

This makes it possible to make the pole 23 stand out and easily use it as a landmark even when visibility is poor.

Moreover, in this embodiment, the hopper 11a is applied to a crusher.

This makes it possible to accurately charge the objects to be crushed into the hopper 11a.

Moreover, in this embodiment, the hopper 11a is applied to the mobile crusher 100.

Thereby, even if the position of the hopper 11a changes together with the mobile crusher 100, the operation of charging the hopper 11a can be performed stably and accurately.

Although the preferred embodiments of the present invention have been described above, the above configuration can be modified as follows, for example.

The number of poles 23 can be 1 to 3, or 5 or more. The position of the pole 23 can also be set to an appropriate position where it can easily serve as a landmark for the driver.

The material of the pole 23 may be, for example, a metal spring instead of the synthetic resin as described above.

The pole 23 can also be made of a member that does not undergo elastic deformation.

The pole 23 may be directly fixed to the inner wall of the hopper 11a instead of the liner 19. The liner 19 can also be omitted in the hopper 11a.

Instead of changing the color of the entire pole 23, the color of a part of the pole 23 (for example, the color of the reflective sheet 24) may be changed.

The color of the poles 23 may be the same for all poles 23.

The reflective sheet 24 of the pole 23 may be omitted.

The work of charging objects to be crushed into the hopper 11a may be performed by a working machine other than the backhoe 101.

The hopper 11a may be included in a non-mobile crusher (fixed crusher). Furthermore, the present invention can be widely applied to processing machines equipped with a hopper into which any object can be thrown.

The hopper 11a can also be applied to a sorter or a mobile sorter.
