[0002] Concrete, or simply "concrete", is a general term for engineering composite materials in which aggregates are bound together by cementing materials. Generally speaking, concrete refers to cement concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. During the concrete production process, it is necessary to transport various raw materials for concrete.

[0003] A search revealed a Chinese patent (application number "202323565102.1") disclosing "a concrete raw material conveying device." This conveying device includes a frame, a conveyor belt mounted on the surface of the frame, and a cleaning device on the surface of the frame.

However, the above-mentioned conveying device has the following problems when conveying powdered raw materials:

[0004] 1. Materials above the conveyor belt will slip under the influence of gravity, resulting in insufficient material being transported into the production equipment and poor conveying efficiency;

[0005] 2. The dust in the materials was not collected, and the dust drifted into the external environment, resulting in poor environmental performance. Utility Model Content

[0006] This utility model provides a concrete feeding and conveying device, which solves the problems proposed in the prior art where the separation device for conveying powdery materials causes the materials to slip under the influence of gravity, resulting in insufficient material delivery into the production equipment, poor conveying efficiency, and the lack of dust collection, leading to dust dispersion in the external environment and poor environmental performance.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A concrete feeding and conveying device includes a base frame, with an installation mechanism on the top of the base frame. The installation mechanism includes a conveying cylinder, a feed hopper welded to the lower outer wall of one side of the conveying cylinder, and a discharge hopper welded to the upper outer wall of one side of the conveying cylinder. A conveying assembly is provided inside the conveying cylinder. The conveying assembly includes a drive shaft with ventilation slots on its bottom outer wall and spiral blades with internal air ducts. A transmission assembly is provided on the upper part of the conveying cylinder. The transmission assembly includes a drive motor and a rotating shaft connected to the top of the output shaft of the drive motor via a coupling. A first dust removal mechanism is provided above the feed hopper. The system includes a mounting plate, a mounting cylinder bolted to one outer wall of the mounting plate, a first fixing ring welded to one inner wall of the mounting cylinder, a first filter bag connected to the outer wall of the first fixing ring by clamps, a cover plate bolted to one outer wall of the mounting cylinder, and a first dust removal fan bolted to one outer wall of the cover plate. A second dust removal mechanism is provided on the upper part of one side of the conveying cylinder. The second dust removal mechanism includes a mounting box, a second fixing ring welded to the inner wall of the top of the mounting box, a second filter bag connected to the outer wall of the second fixing ring by clamps, and a second dust removal fan bolted to the outer wall of the bottom of the mounting box.

[0009] Preferably, a lower end cover is bolted to the bottom outer wall of the conveying cylinder, and the lower end cover is bolted to the top outer wall of the bottom frame. An upper end cover is bolted to the top outer wall of the conveying cylinder.

[0010] Preferably, both ends of the drive shaft pass through and are connected to the outer walls of the lower end cover and the upper end cover respectively through bearings. A spiral air outlet groove is opened at the welding position between the lower part of the drive shaft and the spiral blade. An air outlet is opened on the upper outer wall of the spiral blade. An air inlet pipe is connected to the lower outer wall of the drive shaft through a rotary joint. One end of the air inlet pipe passes through and is fixed to the outer wall of one side of the bottom frame. A driven synchronous pulley is connected to the upper outer wall of the drive shaft through a pin.

[0011] Preferably, a mounting base is welded to the upper outer wall of the conveying cylinder, and the drive motor is bolted to the bottom outer wall of the mounting base. A drive synchronizing pulley is connected to the upper outer wall of the rotating shaft by a pin, and the drive synchronizing pulley and the driven synchronizing pulley form a transmission engagement through a synchronous belt.

[0012] The above scheme uses a drive motor output shaft to drive the drive shaft and spiral blades to rotate. The spiral blades transport the material in the feed hopper and then discharge the material into the production equipment through the discharge hopper. At the same time, the air inlet pipe is connected to a hot air source, and the hot air enters the space below the drive shaft. Then, the hot air enters the air duct inside the spiral blades along the air outlet groove. The hot air heats the spiral blades, which in turn heats the material, reducing the clumping that occurs when the material is damp.

[0013] Preferably, fixing plates are bolted to the outer walls on both sides of the bottom frame, and the two fixing plates are respectively bolted to the outer walls on both sides of the mounting base.

[0014] Preferably, the mounting plate is bolted to one outer wall of two fixing plates, and a dust collection hood is bolted to the outer wall of the opposite side of the two fixing plates. A conveying pipe is fixed on the inner wall of the top of the dust collection hood, and one end of the conveying pipe passes through and is fixed to the inner wall of the mounting cylinder.

[0015] The above scheme uses the first dust removal fan to draw dust from the lower part of the dust collection hood and the upper part of the feed hopper into the installation cylinder, and then the first filter bag collects the dust generated during feeding.

[0016] Preferably, an installation block is welded to the upper outer wall of one side of the conveying cylinder, and the installation box is bolted to the outer wall of the installation block. A connecting pipe is fixed to the inner wall of the top of the installation box, and one end of the connecting pipe passes through and is fixed to the outer wall of the upper end cover. A door is hinged to the outer wall of one side of the installation box.

[0017] The above method involves using a second dust removal fan to draw the air discharged from the spiral blades into the mounting box, and to carry a small amount of dust from the spiral blades into the second filter bag.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The output shaft of the drive motor drives the drive shaft and the spiral blades to rotate. The spiral blades convey the material in the feed hopper and then discharge the material into the production equipment through the discharge hopper. At the same time, the air inlet pipe is connected to a hot air source, and the hot air enters the space under the drive shaft. Then, the hot air enters the air duct inside the spiral blades along the air outlet groove. The hot air heats the spiral blades, which in turn heats the material, reducing the clumping caused by the material being damp. This enables stable material conveying, prevents material slippage, and improves conveying efficiency.

[0020] 2. The first dust collector blower draws the dust from the lower part of the dust collection hood and the upper part of the feed hopper into the installation cylinder. Then, the first filter bag collects the dust generated during feeding. The second dust collector blower draws the air discharged from the spiral blades into the installation box and carries a small amount of dust on the spiral blades into the second filter bag. This process can collect the dust generated during feeding, prevent the dust from drifting into the external environment, and improve environmental protection.

[0021] In summary, this utility model can stably convey materials, prevent materials from slipping, improve conveying efficiency, and collect dust generated during feeding, preventing dust from drifting into the external environment and improving environmental protection.
