Description

Technical Field

[0001] The utility model relates to the field of stone transportation industry, in particular to a material blocking device for stone transportation. Background Art

[0002] Stone is a rock or a rock-like substance used for construction, sculpture, etc. Stone generally refers to all stones that can be used as materials, such as granite, shale, mudstone, etc. Stone piles, stone masonry, and slag are also stones. In construction projects, stone is widely used in ground paving, columns, walls, doors, windows, steps, etc., and stone transportation is the transportation of stone for easy construction.

[0003] Most of the current material blocking devices are located on both sides of the conveyor belt and are in the shape of plates. Their function is to prevent stones from falling during transportation. However, most stones are irregular in shape. During transportation, their corners have no force unloading guides and will directly collide with the material blocking plate, resulting in a shorter service life. In addition, the height and angle of the baffle are not easy to adjust. Some stones are easy to fall from the edge of the conveyor belt, which increases the difficulty of cleaning the fallen stones for the staff. At the same time, the falling of stones may lead to a reduction in the transported stones, affecting the transportation efficiency and affecting the construction use.

[0004] The existing patent application number is 201910798801.X, which is a mining stone loading and unloading equipment, including a frame and a protective structure. The protective structure includes a fixed frame, a buffer rotating structure, a support structure, and an edge plate. The fixed frame is installed on both sides of the frame and welded to each other. The buffer rotating structure is embedded and installed on the inner side of the fixed frame. The support structure is installed on the outside of the buffer rotating structure and is mechanically connected. The edge plate is horizontally arranged above the support structure and is an integrated structure. Under the action of the buffer rotating structure, the support structure is folded outward by the downward pressure of the stone, which can reduce the instantaneous gravity when the stone is put down. The structure is relatively complicated. Adding a drop hopper to the conveyor belt can also reduce the instantaneous downward pressure on the conveyor belt. When the stone is transported, the structure still cannot avoid the corners of the stone from directly colliding with the baffle plate, affecting the service life of the structure. In addition, in this scheme, if the stone is large, the support structure will be pressed and folded, and the stone is prone to falling. Utility Model Content

[0005] The utility model provides a material blocking device for stone conveying, so as to solve the technical problem in the prior art that stones directly hit the baffle plate without unloading force and the baffle plate cannot be raised or lowered, resulting in the stones falling.

[0006] To solve the above problems, the utility model provides a material blocking device for stone conveying, which adopts the following technical scheme: it includes a frame, a symmetrically arranged conveying frame is provided on the top of the frame, a transmission belt is provided between the two conveying frames, side compartment frames fixed to the top of the conveying frames are provided on both sides of the transmission belt, the side compartment frames are provided with blocking columns slidingly matched with the side compartment frames, a plurality of blocking columns are provided and arranged in a row along the side compartment frames, an upper lifting plate rotatably connected to the top of the blocking column is provided, lifting boxes are provided on both sides of the side compartment frames, a rack fixedly connected to the upper lifting plate is provided in the lifting box, a gear meshingly connected to the upper lifting plate is provided outside the rack, the rack is also provided with a roller rotatably matched with the rack, and a guide rail fixed in the lifting box and limitedly matched with the rack is provided outside the roller.

[0007] Furthermore, a lower lifting plate rotatably connected to the bottom of the blocking column is provided, and the lower lifting plate is slidably connected to the inner wall of the side compartment frame.

[0008] Furthermore, the top and bottom of the blocking column are connected to the upper lifting plate and the lower lifting plate respectively through bearings.

[0009] Furthermore, a connecting block is fixed to the bottom of the upper lifting plate, and the connecting block is fixedly installed with the rack and is gap-matched with the roller.

[0010] Furthermore, the gear is rotatably connected to the inner wall of the lifting box, and a lifting motor is arranged outside the gear to drive the gear to rotate.

[0011] Furthermore, a plurality of transmission wheels rotatably matched with the conveying frame are provided at the bottom of the transmission belt, and the transmission wheels are arranged in a line along the outer side of the conveying frame.

[0012] Furthermore, a wheel frame is fixed at the bottom of the conveying frame, and two belt pulling wheels that are in close contact with the transmission belt are symmetrically arranged outside the wheel frame.

[0013] Furthermore, the wheel frame is also provided with a driving wheel for driving the transmission belt to rotate, the driving wheel is located at the center bottom of the two pulleys, and a transmission motor is also provided on one side of the driving wheel to drive it to rotate.

[0014] The beneficial effect of the material blocking device for stone conveying provided by the utility model is that the stone moves along with the transmission belt, and during the movement, when the stone with irregular surface shape collides with the blocking column, since the blocking column is rotatably arranged, it rotates to unload the force when colliding. Compared with the traditional plate-shaped material blocking device, it has a longer service life, and when the stone volume is large or the height exceeds the current height of the blocking column, the gear rotates to drive the rack to move along the guide rail surface, so that it drives the upper lifting plate to move up, thereby changing the current material blocking height, so that the stone will not fall from the edge of the transmission belt, reducing the difficulty of cleaning the fallen stone for the staff, and at the same time avoiding the situation of reduced conveyed stone due to the falling stone, thereby ensuring the efficiency of transportation and preventing it from affecting construction use.
