Description

Primary and secondary vehicle equipment for brick making system

Technical Field

The utility model belongs to the technical field of the brickmaking equipment, especially, relate to a primary and secondary car equipment for brickmaking system.

Background

In the technical field of brick making (such as paving bricks and the like), along with the development of the technology, the traditional brick making system requiring more manual participation is gradually replaced by a semi-automatic system or even a fully-automatic system. The automation level of the brick making system is continuously improved, and the method has very important significance for improving the brick making processing efficiency, ensuring the quality of brick products, reducing the labor cost and reducing the personnel danger. The automatic level of the brick making system is generally improved, and the automatic level of the brick making system generally comprises three aspects of the automatic level of brick making equipment, the automatic level of loading the brick making equipment, and the automatic level of blanking and transporting the green bricks to a curing place. The transfer efficiency of the green bricks after blanking is determined by the automation level of the green bricks transfer, and the transfer has very important influence on the brick making processing efficiency of the whole brick making system.

The working process of the brick machine equipment is as follows: the feeding machine sends the blank into the lower die, the distributing device paves and distributes the blank in the lower die, the upper die descends to carry out compression molding on the blank, a vibrator is adopted to vibrate in the compression molding process to ensure the compactness of the formed green brick, and then the green brick is transferred out from the brick making equipment by the brick supporting plate carrying the formed green brick and is conveyed to a curing place to carry out curing treatment. From the working process, the transfer of the green bricks obtained after compression molding from the brick making equipment to the maintenance place is a more critical process, and the operation efficiency directly determines whether the transfer process becomes the bottleneck process of a brick making system.

In order to save maintenance space, the green bricks are generally stacked in a stacking manner, and multiple layers of green bricks are stacked in the vertical direction (a layer of brick supporting plate is arranged below each layer of green bricks). Considering that the green bricks which are just finished with compression molding can not be directly stacked due to the factors in the aspect of structural strength, the green bricks need to be subjected to standing treatment for a certain time, and then stacked after the strength is improved. Therefore, the green bricks sent out from the brick discharging device of the brick making system are transferred to a standing area for standing, and the method becomes an important step before stacking and curing.

The existing mode of transferring green bricks to a standing area is generally manual transfer, specifically: a manually driven transfer vehicle is arranged at a brick discharging device of the brick machine equipment, and when a brick supporting plate carries a pressed and molded green brick and is transferred to the transfer vehicle, a person drives the transfer vehicle to transfer the green brick to a standing area.

The above operation mode has the following problems: (1) the space of the brick discharging device is narrow, and the transfer vehicle facility is not easy to drive into and out of the area, so that the transfer efficiency is reduced; (2) the path of movement of the manually driven transport vehicle is not precisely defined, resulting in some cases in collisions of the transport vehicle with the frame of the brick machine installation; (3) the transfer of the green brick-carrying carrier plate from the brick discharge device to the transfer trolley requires the provision of a transfer mechanism for the brick discharge device, which increases the structural complexity of the brick discharge device.

Therefore, a new facility for transferring the green bricks should be developed and designed, and the facility is matched with a brick discharging device of brick machine equipment for use, so that the manufactured green bricks can be quickly and stably transferred to a standing area.
