Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering material conveying devices, in particular to a construction engineering material conveying device. Background Art

[0002] A shaftless screw conveyor is a machine for conveying items. Compared with traditional shafted screw conveyors, it adopts a center shaftless design and uses a flexible integral steel screw to push materials. The machine can convey materials horizontally, tilted or vertically. It is suitable for conveying powdered, granular and small block materials and is widely used in industries such as building materials, chemicals, electricity, metallurgy, coal, and grain.

[0003] There is a shaftless screw conveyor with a hose on the market that can efficiently transport sand and gravel in construction projects. The shaftless screw conveyor with a hose is mainly composed of a hose, a screw conveyor, a sealing head and wiring. It pushes particles, powders, liquids and other materials into the hose through the screw conveyor and conveys them with the help of pressure, finally delivering the materials to the designated location.

[0004] When the hose shaftless screw conveyor is in use, the front end of the screw conveyor is inserted into the middle of the material, and the material is driven into the hose for conveying by the rotating screw conveyor. However, this operation method requires the material to have a certain stacking height. When the material stacking height is not enough for the insertion depth of the screw conveyor, the staff needs to manually shovel the material onto the screw conveyor with tools. Since the front end of the screw conveyor on the existing hose shaftless screw conveyor has unlimited obstruction, when the material is manually shoveled onto the screw conveyor, most of the material falls to one side of the screw conveyor and will not be taken away, which leads to low conveying efficiency. Based on this, a material conveying device for construction projects is provided. Utility Model Content

The shaftless screw conveyor 104 extends through the discharge hopper 102 and the hose 101 to the inside of the front end assembly 105. The front end assembly 105 is composed of a conical head 1051, a connecting rod 1052, a connecting inner cylinder 1053, an outer cylinder 1054, and a tail shaft 1055.

[0029] A plurality of connecting rods 1052 are provided, and the plurality of connecting rods 1052 are distributed in a ring and fixed between the conical head 1051 and the connecting inner tube 1053. The outer tube 1054 is fixed to the outside of the connecting inner tube 1053. The connecting inner tube 1053 and the outer tube 1054 are respectively sleeved and installed on the inside and outside of the front end of the hose 101.

[0030] The length of the connecting inner tube 1053 is greater than that of the outer tube 1054, and the outer side of the hose 101 is pressed and fixed to the outer side of the rear end of the connecting inner tube 1053 by a clamp;

[0031] The central axis of the tail shaft 1055 is fixed to the rear end of the conical head 1051 , and the shaftless screw conveyor 104 extends to the middle of the multiple connecting rods 1052 and is fixedly connected to the outer rotor of the tail shaft 1055 ;

[0032] The outer side of the outer cylinder 1054 is provided with a feeding auxiliary component 2, which is retracted outside the outer cylinder 1054 so as not to affect the insertion of the conical head 1051, the connecting rod 1052 and the front end of the shaftless screw conveyor 104 into the material;

[0033] The loading auxiliary component 2 moves to the outer area of ​​the connecting rod 1052 to provide a loading limit for the shaftless screw conveyor 104, facilitating manual loading operations;

[0034] The feeding auxiliary component 2 includes a movable sleeve 201, a limiting convex strip 202, and a feeding port 203;

[0035] The outer sides of the outer cylinder 1054 are integrally formed with limiting rail grooves 1056. The limiting rail grooves 1056 do not pass through the rear end of the outer cylinder 1054. The limiting ridges 202 are symmetrically formed on the inner side of the movable sleeve 201. The movable sleeve 201 is slidably sleeved on the outer side of the outer cylinder 1054. The limiting ridges 202 are slidably connected to the outer cylinder 1054. The loading port 203 is fixed to the top of the movable sleeve 201 and is conductively connected to the inner side of the movable sleeve 201.

[0036] The movable sleeve 201 moves horizontally to the outside of the connecting rod 1052 along the track of the limiting rail groove 1056 through the limiting ridge 202, and is used to block the peripheral area of ​​the shaftless screw conveyor 104, and is used to provide a material guide operation for manual loading through the loading port 203.

[0037] In this embodiment: when this hose screw conveyor 1 is used to convey sand and gravel, it is only necessary to install the discharge hopper 102 at the place to be discharged, and then insert the conical head 1051 and the connecting rod 1052 into the sand and gravel pile (it should be noted that the default initial state of the loading auxiliary component 2 is retracted outside the outer cylinder 1054), and then start the drive motor 103, and the drive motor 103 drives the shaftless screw conveyor 104 to rotate, and the front end of the shaftless screw conveyor 104 is inserted into the sand and gravel pile together with the connecting rod 1052. At this time, the rotating shaftless screw conveyor 104 can drive the sand and gravel into the hose 101, and move it along the channel inside the hose 101 to the discharge hopper 102, and finally fall out through the discharge hopper 102, thereby realizing the transportation of sand and gravel;

[0038] When the sand and gravel are piled up high enough for the cone head 1051 and the connecting rod 1052 to be fully inserted, the sand and gravel can be manually shoveled onto the shaftless screw conveyor 104. The operation method is as follows:

[0039] First, manually move the movable sleeve 201 and the loading port 203 as a whole to the outside of the connecting rod 1052. When the movable sleeve 201 completely covers the connecting rod 1052, manually shovel the sand and gravel into the loading port 203. The sand and gravel fall into the movable sleeve 201 through the loading port 203 and contact the shaftless screw conveyor 104 along the gap of the connecting rod 1052. The movable sleeve 201 can wrap and limit the sand and gravel, so that the sand and gravel can be better taken away by the rotating shaftless screw conveyor 104, thereby ensuring efficient transportation effect.

[0040] Please refer to Figures 1 to 4 , the loading auxiliary assembly 2 also includes a lifting handle 204, a locking bolt 205, and a horizontal bottom plate 206;

[0041] The lifting handle 204 is fixed at the top middle position of the loading port 203 and is used to provide a handhold for manual lifting;

[0042] The horizontal base plate 206 is fixed to the bottom of the movable sleeve 201 and is used to provide support for the movable sleeve 201 to be placed horizontally on the ground;

[0043] The horizontal length of the movable sleeve 201 is greater than the horizontal length of the connecting rod 1052. The locking bolt 205 is threadedly connected to the top rear end of the movable sleeve 201 and passes through the movable sleeve 201 and fits tightly against the outer wall of the outer cylinder 1054, so as to achieve relative fixation of the movable sleeve 201 and the outer cylinder 1054.

[0044] In this embodiment, when the movable sleeve 201 is retracted and sleeved on the outside of the outer tube 1054, the front end of the hose 101 and the front end assembly 105 can be conveniently moved by pulling the handle 204. At the same time, when the movable sleeve 201 needs to be moved, it can also be operated by pulling the handle 204.

[0045] When the movable sleeve 201 is moved, the locking bolt 205 must be loosened first to release the locking bolt 205 from the pressed state with the outer cylinder 1054. When the movable sleeve 201 completely blocks the connecting rod 1052, the rear end of the movable sleeve 201 is still outside the outer cylinder 1054. At this time, the locking bolt 205 is tightened to press it against the outer cylinder 1054 again, so that the position of the movable sleeve 201 can be fixed.

[0046] In addition, the horizontal bottom plate 206 is used to enable the movable sleeve 201 to be placed stably on the ground, which facilitates subsequent stable manual loading operations.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
