BACKGROUND ART Various types of catalysts are used in petroleum refining facilities, chemical industry facilities, etc. to promote chemical reactions.
The catalyst is used by filling the inside of the reactor in which the raw material fluid flows. When the reactor is used for a long period of time, dirt such as carbon adheres to the surface of the catalyst and solidifies the catalysts.
This solidified catalyst does not come into contact with the raw material fluid,
The effect of promoting the chemical reaction is lost. For this reason, the reactor regularly replaces a catalyst that has become clogged and cannot be used with a new catalyst. In order to replace the catalyst, it is first necessary to remove the solidified catalyst from the reactor. In carrying out the operation of unloading the catalyst (unloading work), the manhole of the reactor is opened, and the worker is sent from the manhole into the reactor, and a handheld rock drill or hammer is carried into the reactor. Then, the hose of the vacuum suction device was pulled in from the outside of the reactor, and the operator crushed the solidified catalyst with a rock drill, further crushed the crushed catalyst with a hammer, and crushed the crushed catalyst into a vacuum suction device. It sucks with a hose, so that the catalyst that cannot be used anymore is taken out of the reactor.

Since the work of the worker inside such a reactor is a heavy labor,
It is desired to further promote labor saving and labor saving by increasing the size and strength of machines such as rock drills. However, there is a problem in that it is difficult to send a powerful large machine into the reactor due to the size of the manhole provided in the reactor. Also, it is conceivable that a large number of small automatic machines are sent into the reactor.However, since complicated internal devices such as distribution trays are installed inside the reactors, There is a problem that it is difficult to take the place of

[0004] It is an object of the present invention to provide a catalyst unloading machine in which work is further mechanized and labor and labor are further reduced.
