Description

an unloading machine

technical field

The invention relates to a bulk material unloading machine.

Background technique

Unloading of bulk cargo, such as unloading bulk cargo such as cement and rice from ships to warehouses or other vehicles at the port, some unloading machines use negative pressure suction, which consumes a lot of energy and is low in efficiency. Bulk unloading machines also use conveyor belts, but this type of unloading machine has a slow conveying speed and can only be unloaded at a fixed location, which affects the loading and unloading efficiency of the entire port.

Contents of the invention

The technical problem to be solved by the invention is to provide an unloading machine with low energy consumption and fast unloading speed. For this reason, the present invention adopts following technical scheme: it comprises vertical feeding device, transfer device, the supporting device of vertical feeding device and transfer device, rotating tower; The lower part of the feeding tube is covered with a rotatable outer tube with helical blades on the surface, and the lower part of the outer tube is connected with a tapered feeding head. There is a feeding port on the side of the feeding head. The transfer device includes a transfer feeding pipe and a transfer screw feeder arranged in the pipe. The feeding port of the transferring feeding pipe is connected with the outlet of the vertical feeding pipe. Both the pipe and the transfer feeding pipe are composed of several pipe sections connected, and the joints of the pipe sections are provided with rotating supports for the screw feeder. Due to the adoption of the above technical scheme, the present invention adopts the method of screw feeder to transport materials, and the energy consumption is more than several times less than that of negative pressure unloading, and, through the combination of rotatable outer tube pressing material and vertical screw feeder feeding, The vertical screw feeder can rotate and feed at high speed to increase the unloading speed. At the same time, a feeding grill is set on the reclaimer to effectively connect the pressing action of the rotatable outer tube with the feeding action of the vertical screw feeder, which greatly improves The unloading speed is improved, and at the same time, the invention divides the feeding pipe into several sections, which can not only extend the conveying distance, adapt to different working conditions, but also reduce the difficulty of installation and manufacturing.

The rotation axis of the transfer screw feeder is lower than the center line of the outlet of the vertical feeding pipe. The transfer feeding pipe is provided with a buffer box at the communication point with the vertical feeding pipe, and is connected to the vertical feeding pipe through the shell part of the buffer box. With this structure, the transfer structure is simple and reliable, and the cost is low and the installation is convenient.

Each section of the transfer feeding pipe is connected by a short pipe. The rotating shaft of the transfer screw feeder is divided into corresponding sections and connected by a connecting shaft. The connecting shaft sleeve has a bearing, and the bearing is installed on the suspender. Fixed on the mounting plate on the surface of the short pipe. The bearing is a two-half structure, the lower half is threadedly connected with the suspender, the upper half is sleeved on the suspender, and the top is positioned and fastened by the suspender. This structure is more convenient for installation and parts replacement.

A discharge channel matched with the discharge port of the transfer feeding pipe is provided in the rotating turret, and a discharge flowmeter is provided in the channel. With this structure, the space of the tower can be fully utilized, and the goods can be directly measured, so as to facilitate the measurement review and ensure the accuracy of unloading.
