Description

Technical Field

[0001] The present application relates to the technical field of construction engineering, and more specifically, to a high-sealing screw conveyor for construction engineering. Background Art

[0002] In construction projects, screw conveyors are often needed to transport some materials, such as powder materials such as cement, and fluid materials such as mortar. The rotating spiral blades of the screw conveyor push the materials for spiral transportation.

[0003] The document with prior art publication number CN207242745U provides a high-seal screw conveyor for construction projects, including a shell and a rotating shaft arranged in the shell and extending out of the shell at both ends, the rotating shaft is located in the shell and has spiral blades on the outer wall, a hopper is provided above one end of the shell close to the power device, and a discharge port is provided below the rotating shaft at the other end, characterized in that: the pitch between the spiral blades gradually decreases from the end close to the hopper to the end away from the hopper, and the shaft diameter of the rotating shaft gradually increases from the end close to the hopper to the end away from the hopper; the utility model is that: the pitch between the spiral blades gradually decreases from the end close to the hopper to the end away from the hopper.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, they still have the following defects:

[0005] The discharge port is generally downward and lacks a sealed closed structure. When conveying fine or fluid materials such as cement ash and mortar, after a certain amount of material is received at the bottom of the discharge port and the motor stops, the material in the shell will fall from the discharge port to the ground due to its own weight, resulting in waste.

[0006] Regarding the above-mentioned related technologies, the inventor believes that the discharge port is generally downward and lacks a sealed closing structure. When transporting fine materials or fluid materials such as cement ash and mortar, when a certain amount of material is received at the bottom of the discharge port and the motor stops, the material in the shell will fall from the discharge port to the ground due to its own weight, resulting in waste.

[0007] In view of this, we propose a high-sealing screw conveyor for construction engineering. Utility Model Content

[0008] 1. Technical problems to be solved

[0009] The purpose of the present application is to provide a high-sealing screw conveyor for construction projects, which solves the technical problem that the discharge port in the above-mentioned background technology is generally downward and lacks a sealed closing structure. When conveying fine materials or materials with fluid characteristics such as cement ash and mortar, after a certain amount of material is received at the bottom of the discharge port and the motor stops, the material in the shell will fall from the discharge port to the ground due to its own weight, resulting in waste, thereby achieving a technical effect.

[0010] 2. Technical solution

[0011] The technical solution of the present application provides a high-sealing screw conveyor for construction engineering, comprising:

[0012] A housing, wherein a base is fixedly mounted on the bottom of the housing;

[0013] A feed inlet and a discharge outlet are fixedly installed on the top of one end and the bottom of the other end of the shell respectively;

[0014] A rotating shaft is rotatably sleeved in the shell, and a spiral blade is fixedly mounted on the rotating shaft in the shell;

[0015] A motor is fixedly mounted on the outer wall of one end of the housing close to the feed inlet, and the output shaft of the motor is fixedly connected to the rotating shaft;

[0016] A closing mechanism is installed at the discharge port;

[0017] A control mechanism is installed between the rotating shaft and the outer wall of the shell, and the control mechanism is electrically connected to the closing mechanism.

[0018] Through the above scheme, the base contacts the ground, the feed port faces the outlet of the mixer and other machines, the motor drives the shaft to rotate, and the material is transported to the outlet through the spiral blades. When the shaft rotates, the control mechanism controls the closing mechanism to open, and the material is transported and dropped normally. When the shaft stops transporting, the control mechanism automatically controls the closing mechanism to close, thereby avoiding the waste of material falling from the outlet.

[0019] Optionally, sealed bearings are installed between the two ends of the shell and the rotating shaft, the discharge port is a hollow rectangular structure with a square cross-section, the closing mechanism includes a mounting frame, the bottom outer wall of the discharge port is fixedly mounted with the mounting frame, storage grooves are opened between the mounting frame and the four inner walls of the discharge port, sealing plates are slidably engaged in the storage grooves, a plurality of guide rods penetrating the outer wall of the mounting frame are fixedly mounted on the sealing plates, springs are sleeved on the guide rods between the sealing plates and the inner walls of the storage grooves, a plurality of electromagnets connected to the storage grooves are fixedly sleeved around the mounting frame, and the electromagnets are electrically connected to the control mechanism.

[0020] Through the above scheme, when the shaft stops rotating and stops conveying materials, the control mechanism controls the electromagnet to cut off the power, and the sealing plate is then ejected out of the storage slot by the spring force, thereby closing the discharge port to prevent the material from automatically falling and being wasted. During transportation, the shaft rotates to enable the control mechanism to energize the electromagnet, and the electromagnet magnetic force absorbs the sealing plate, causing the sealing plate to slide into the storage slot, and the discharge port automatically opens to facilitate the falling of materials.

[0021] Optionally, the control mechanism includes a fixed plate, which is fixedly mounted on the outer wall of the shell at the discharge port, a swivel is rotatably clamped on the fixed plate, a short shaft is fixedly mounted on the middle part of the top surface of the swivel, and a meshing bevel gear is installed between the short shaft and the end surface of the rotating shaft, a fixed column is fixedly mounted on the bottom of the fixed plate, the fixed column is rotatably sleeved on the bottom of the swivel, a first brush is installed between the fixed column and the inner wall of the swivel, a second brush is installed between the outer wall of the swivel and the inner wall of the fixed plate, a slide groove is opened in the swivel, a conductive ball is slidably clamped in the slide groove, a first contact is fixedly embedded in the bottom surface of the slide groove, the first contact is electrically connected to the first brush, a second contact is fixedly mounted on the inner wall of the slide groove close to the second brush, and the second contact is electrically connected to the second brush, the slide groove is an inclined structure, and the end close to the second brush is higher, a wire electrically connected to the first brush is fixedly sleeved in the fixed column, and a wire electrically connected to the electromagnet and the second brush is fixedly sleeved on the fixed plate.

[0022] Through the above scheme, when materials are conveyed, the rotating shaft drives the rotating ring to rotate through the bevel gear, the first brush satisfies the electrical connection between the external power line and the first contact, and the second brush satisfies the electrical connection between the electromagnet and the second contact. Then, when conveying materials, the centrifugal force of the rotating ring causes the conductive ball to slide from the lower end of the slide groove to the higher end, thereby connecting the first contact and the second contact. At this time, the electromagnet is energized to open the discharge port. When the material is not conveyed, the rotating ring does not rotate, and the conductive ball slides to the lower end of the slide groove under its own gravity, the first contact and the second contact are disconnected, the electromagnet is powered off, and the sealing plate closes the discharge port, thereby achieving the purpose of automatic sealing and avoiding material falling and waste.

[0023] 3. Beneficial effects

[0024] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0025] 1. When the present application is conveying materials, the rotating shaft drives the rotating ring to rotate through the bevel gear, the first brush satisfies the electrical connection between the external power line and the first contact, and the second brush satisfies the electrical connection between the electromagnet and the second contact. When conveying materials, the centrifugal force of the rotating ring causes the conductive ball to slide from the lower end to the higher end of the chute, thereby connecting the first contact and the second contact. At this time, the electromagnet is energized, and the electromagnet magnetic force attracts the sealing plate, causing the sealing plate to slide into the storage slot, and the discharge port is automatically opened to facilitate the falling of materials, thereby meeting the conveying needs;

[0026] 2. When the material is not being transported, the rotating ring does not rotate. The conductive ball slides to the lower end of the chute under its own gravity. The first contact and the second contact are disconnected, and the electromagnet is powered off. At this time, the sealing plate is ejected from the storage slot by the spring force, thereby sealing the discharge port to prevent the material from automatically falling and wasting.

At this time, the sealing plate 83 is ejected out of the storage groove 82 by the elastic force of the spring 85, thereby closing the discharge port 4 to prevent the material from automatically falling and wasting.

When conveying materials, the centrifugal force of the rotation of the rotating ring 92 causes the conductive ball 97 to slide from the lower end of the slide slot 96 to the higher end, thereby connecting the first contact 98 and the second contact 99. At this time, the electromagnet 86 is energized, and the electromagnet 86 magnetically absorbs the sealing plate 83, so that the sealing plate 83 slides into the storage slot 82, and the discharge port 4 automatically opens to facilitate the falling of materials. When materials are not conveyed, the rotating ring 92 does not rotate, and the conductive ball 97 slides to the lower end of the slide slot 96 under its own gravity, the first contact 98 and the second contact 99 are disconnected, and the electromagnet 86 is powered off.
