Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a hopper clogging prevention device applied to a hopper that stores a handling material such as coal or coke.

[0002]

[Prior art]

 Conventionally, as a hopper clogging prevention device of this type, for example, a device described in Japanese Utility Model Laid-Open No. 55-56287 is known. Basically, this is a hopper that stores items to be handled, a lever member that is swingably provided on the side wall of the hopper, a holding arm that is provided on the hopper and that extends into the hopper, and It is composed of a stone box provided and a balance weight provided on the lever member to balance with the stone box. However, in such a thing, the clogging of the hopper is prevented by utilizing the collision energy against the stone box of the object to be thrown into the hopper, so that the clogging cannot be prevented reliably. However, clogging could not be prevented regardless of what was handled.

[0003]

[Problems to be solved by the device]

 The present invention was devised in order to solve this problem in view of the above problems, and the purpose of the present invention is to make sure that clogging can be prevented irrespective of the loading of the items to be handled. It is to provide a device for preventing clogging of paper.

[0004]

[Means for Solving the Problems]

 The hopper clogging prevention device of the present invention is basically a hopper that stores the items to be handled and a hopper that penetrates through the hopper and is located outside the hopper to project into the hopper to form a narrow portion. It is characterized in that it consists of a push rod that can move the remaining handling material from below to a protruding position and an actuator that operates the push rod.

[0005]

[Action]

 The items to be handled are put into the hopper, stored, and then discharged. At this time, if the material above the narrow space is not discharged and stays, so-called clogging occurs. When clogging occurs, the actuator moves the thrust rod from the housed position to the projected position. Then, the stick is projected into the hopper, a part of the handling object that remains in the narrow part is pushed up from below, and the handling object around the handling object is dropped, whereby clogging is eliminated.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway side view showing a clogging state of a hopper clogging prevention device according to a first embodiment of the present invention. FIG. 2 is a similar view showing a clogging elimination state. The hopper clogging prevention device 1 is mainly composed of a hopper 2, a thrust rod 3, and an actuator 4. The hopper 2 forms a basic part of the hopper clogging prevention device 1, and in this example, it stores the handling material A such as coal and coke used in cupola, and the side wall 5 forms a funnel shape. An inlet 6 is formed in the upper portion, an outlet 7 is formed in the lower portion, and a narrow portion 8 is formed in the lower portion. Below the discharge port 7, there is provided a belt conveyor 9 for laterally transferring the article A (right side in FIG. 1). The push rod 3 is provided so as to penetrate the hopper 2 and is movable from a storage position located outside the hopper 2 to a projecting position where the handling object A that projects into the hopper 2 and stays in the narrow portion 8 is pushed up from below. In this example, the arm 10 and the rod 11 are included. The upper end of the arm 10 is pivotally attached by a pin 13 to a bracket 12 provided on the side wall 5 of the hopper 3. The rod 11 has a base end integrally provided at the lower end of the arm 10 and a distal end penetrated by a through hole 14 formed in the side wall 5, and is formed into an arc shape with the pin 13 as a center. It is designed to pass through without any hindrance. The tip of the rod 11 does not substantially project into the hopper 2 as shown in FIG. 1 when it is in the storage position, and when it is in the projecting position, it projects into the hopper 2 and stays in the narrow portion 8 as shown in FIG. The handle A is pushed up from below. The actuator 4 operates the thrust rod 3. In this example, the actuator 4 is a hydraulic cylinder or the like, and is provided between the upper end of the bracket 12 and the base end of the rod 11 of the thrust rod 3. There is. Next, the operation will be described based on such a configuration. The handling material A is loaded from the loading port 6 of the hopper 2 and stored inside, then discharged from the discharging port 7 and laterally transferred by the belt conveyor 9. At this time, as shown in FIG. 1, when the articles A above the narrow portion 8 compete with each other and remain without being discharged, so-called clogging occurs. When clogging occurs, the cylinder, which is the actuator 4, is extended, whereby the thrust rod 3 is moved to the protruding position shown in FIG. Then, the rod 11 of the thrust rod 3 is projected into the hopper 2, and a part of the handling article A remaining in the narrow portion 8 is pushed up from below and the handling article A around it is dropped. The clogging is cleared. When the clogging is eliminated, the cylinder, which is the actuator 4, is contracted, so that the thrust rod 3 is returned to the accommodation position shown in FIG. If the clogging is not cleared sufficiently, the above operation is repeated.

Next, a second embodiment of the present invention will be described with reference to FIG. The second embodiment is different from the first embodiment in that a controller 15 for driving the actuator 4 for each predetermined time for a predetermined time is provided. In this way, the actuator 4 can be so-called automatically controlled.

Next, a third embodiment of the present invention will be described with reference to FIG. In the third embodiment, a detector 16 (for example, an infrared sensor or a limit switch for detecting the presence or absence of the article A on the belt conveyor 9) for detecting that the article A is clogged in the narrow portion 8 of the hopper 2 is used. This is different from the first embodiment in that a controller 17 for driving the actuator 4 for a predetermined time is provided accordingly. In this way, the actuator 4 can be so-called automatically controlled.

In the above embodiment, the thrust rod 3 is composed of the arm 10 and the arcuate rod 11 so as to be swingable. However, the present invention is not limited to this, and it may be composed of only a linear rod, for example. It may be slanted so that it can move linearly upward. Although the cylinder is used as the actuator 4 in the above-described embodiment, the actuator 4 is not limited to this, and may be a motor, for example. Although the thrust rod 3 and the actuator 4 are single in the above embodiment, the present invention is not limited to this, and may be a left and right pair, for example.

[0010]

[Effect of device]

 As described above, according to the present invention, the following excellent effects can be obtained. (1) It is composed of a hopper, a thrust rod, and an actuator. Particularly, since the thrust rod that is provided so as to penetrate the hopper and is movable from the storage position to the protrusion position is operated by the actuator, Clogging can be prevented regardless of what is handled. (2) Since the thrust rod is located outside the hopper when it is in the stowed position, it does not hinder the flow of the items to be handled and allows smooth discharge. (3) When the actuator is so-called automatically controlled, the operation work can be simplified and further labor saving can be achieved.
