Description

Technical Field

[0001] This utility model belongs to the field of conveying equipment technology, specifically referring to a double conveyor belt elevator. Background Technology

[0002] The current inclined chute elevator has the following technical defects:

[0003] 1. Traditional sloping structure means that only 40-50% of the effective volume of the silo can be utilized, resulting in capacity limitation;

[0004] 2. In order to maintain the material's downward movement, an inclination angle of ≥25° is required, and the feeding height often exceeds 1 meter. This results in an excessively high feeding height, which makes manual feeding labor-intensive and poses a high risk factor.

[0005] 3. The continuous friction between the material and the inclined surface leads to a high breakage rate. Utility Model Content

[0006] The technical problem to be solved by this utility model is the low utilization rate of silos, excessive feeding height, and severe material wear in the prior art.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0008] The present invention proposes a double conveyor belt elevator, which includes a frame and a power unit;

[0009] The frame includes a horizontal section and an inclined section inclinedly connected thereto. A hopper is provided on the horizontal section. The frame also includes:

[0010] A horizontal conveyor belt, which is located at the horizontal section and connected to the bottom of the hopper outlet;

[0011] An inclined conveyor belt is provided at the inclined section and its input end is connected to the end of the horizontal conveyor belt. The two form an obtuse angle, preferably 120°-130°. The surface of the inclined conveyor belt is provided with baffles.

[0012] The linkage control system includes a material sensor installed on the side wall of the silo, the power unit drives the horizontal conveyor belt and the inclined conveyor belt to perform transmission motion, and also includes a controller connecting the material sensor and the power unit.

[0013] Preferably, the controller executes the following control logic:

[0014] The horizontal conveyor belt is started when the material sensor does not detect any material for X seconds; the horizontal conveyor belt is stopped when the material sensor detects that the material coverage reaches Y%.

[0015] Preferably, a continuous slat is laid under the horizontal conveyor belt and the inclined conveyor belt, which is fixedly connected to the frame.

[0016] Preferably, the free end of the baffle is inclined in the conveying direction, and the inclination angle can be 5°-15°.

[0017] Preferably, the material sensor is a reflective photoelectric switch, and the detection surface of the reflective photoelectric switch is installed at a height of 20-50mm from the bearing surface of the horizontal conveyor belt.

[0018] Preferably, the inclined conveyor belt has a funnel-shaped discharge chute at its high end.

[0019] Preferably, a tensioning mechanism is provided between the horizontal conveyor belt, the inclined conveyor belt and the power unit.

[0020] The beneficial effects of this utility model by adopting the above structure are as follows:

[0021] 1. This application adopts a double belt conveyor system, which significantly increases the storage capacity of the silo compared to the direct inclined slide method.

[0022] 2. The feeding height has been reduced, which has reduced the labor intensity of manual feeding.

[0023] 3. Since there is no downward pressure generated by material accumulation on the inclined surface, the wear and damage from impacts on the product are greatly reduced or avoided. Attached Figure Description

[0031] Example 1

[0032] like Figure 1-2 As shown, the present invention proposes a double conveyor belt elevator, comprising a frame 1 and a power unit. The frame 1 includes a horizontal section and an inclined section inclinedly connected thereto. A hopper 2 is provided on the horizontal section. The elevator also includes:

[0033] A horizontal conveyor belt 4 is located at the horizontal section and is connected to the bottom of the outlet of the hopper 2;

[0034] An inclined conveyor belt 5 is located at the inclined section and its input end is connected to the end of the horizontal conveyor belt 4. The two form an obtuse angle, preferably 120°-130°. A baffle is provided on the surface of the inclined conveyor belt 5, and a funnel-shaped discharge chute 11 is provided at the bottom of the high end of the inclined conveyor belt 5. The free end of the baffle is inclined in the conveying direction, and the inclination angle can be 5°-15°.

[0035] The linkage control system includes a material sensor 3 installed on the side wall of the silo 2, the power unit drives the horizontal conveyor belt 4 and the inclined conveyor belt 5 to perform transmission motion, and also includes a controller 9 connecting the material sensor 3 and the power unit.

[0036] The material sensor 3 is a reflective photoelectric switch, and the detection surface of the reflective photoelectric switch is installed at a height of 20-50mm from the bearing surface of the horizontal conveyor belt 4.

[0037] In this embodiment, the power unit employs conventional technology, with main rollers 7 and driven rollers 7 respectively positioned at the two ends of the horizontal and inclined sections. Multiple sets of continuously arranged sliding plates 6 are laid beneath the horizontal conveyor belt 4 and the inclined conveyor belt 5 for support. The horizontal conveyor belt 4 and the inclined conveyor belt 5 are rotatably mounted between the two sets of main rollers 7 and driven rollers 7. A motor 8 is located on the side of the frame 1 to drive the main rollers 7 to rotate. The output shaft of the motor 8 drives the main rollers 7 to rotate (a reduction gear can be installed between them). The rotation of the main rollers 7 drives the horizontal conveyor belt 4 / inclined conveyor belt 5 to rotate, which in turn drives the driven rollers 7 to rotate, completing the conveyor belt transport operation. Figure 2 The diagram shown is a schematic of the state where the inclined conveyor belt 5 is hidden.

[0038] In this application, the controller 9 executes the following control logic:

[0039] When material sensor 3 does not detect material for X seconds, horizontal conveyor belt 4 is started; when material sensor 3 detects that the material coverage rate reaches Y%, horizontal conveyor belt 4 is stopped. In use, the speed of inclined conveyor belt 5 can be set to 3-5 times the speed of horizontal conveyor belt 4.

[0040] The working principle is as follows:

[0041] First, pour the material into the hopper 2. The controller 9 consists of a microcontroller and a frequency converter. Set the speed adjustment parameters in the controller 9 and start the equipment. The horizontal conveyor belt 4 slides the material onto the inclined conveyor belt 5. The product is lifted by using the baffle limit. The motor 8 drives the inclined conveyor belt 5 to lift the material. After reaching the top, the material is sent out from the discharge chute 11.

[0042] After the material sensor 3 detects that there is no product, the horizontal conveyor belt 4 sends the product to the inclined conveyor belt 5; after the material sensor 3 detects material, the horizontal conveyor belt 4 stops conveying material to avoid feeding too much material at once. When there is too little material, the horizontal conveyor belt 4 starts conveying again to ensure the stability of the feeding quantity.

[0043] As a further example:

[0044] The horizontal conveyor belt 4, the inclined conveyor belt 5 and the power unit are all provided with a tensioning mechanism 10, which adopts existing technology to prevent the belt from becoming loose after long-term use.

[0045] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
