Material level sensing equipment support, material level sensing mechanism and concrete pumping machine

The invention discloses a material level sensing equipment support, a material level sensing mechanism and a concrete pumping machine. The material level sensing equipment support comprises a first support body and a second support body; the first support body and the second support body are connected in a hinged mode; and the material level sensing equipment support is configured to be capable of being switched between an opening state and a folding state. In the opening state, the first support body and the second frame body can abut against a screen frame of the concrete pumping machine so as to prevent the material level sensing equipment support from falling off from the screen frame; and in the folding state, the first support body and the second frame body can be separated from the screen frame so as to allow the material level sensing equipment support to be separated from the screen frame. The first support body and/or the second frame body are/is used for installing material level sensing equipment.
