Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bulk grain transfer, and in particular to a bulk grain transfer continuous weighing device. Background Art
[0002] Bulk grain is usually stored in multiple cement silos, which are connected by grain transfer pipelines. The grain transfer pipelines are used to transfer bulk grain or take it out of the warehouse.
[0003] When bulk grain passes through a grain transfer pipeline, a chute scale is usually installed on the pipeline to accurately measure the weight of the bulk grain in transit. The chute scale can accurately weigh the bulk grain to assist in warehouse management and business scheduling related to bulk grain transfer.
[0004] Although the chute scale can measure bulk grain, the accuracy of the chute scale's measurement depends on the continuous fluidity of the bulk grain. When the grain transfer pipeline is blocked, the continuous fluidity of the bulk grain will be reduced, which will easily reduce the measurement accuracy of the chute scale. Utility Model Content
[0005] In order to prevent the measurement accuracy of the chute scale from being reduced due to blockage of the grain transfer pipeline, the present application provides a bulk grain transfer continuous weighing device.
[0006] This application provides a bulk grain transfer continuous weighing device, which adopts the following technical solutions:
[0007] A bulk grain transfer continuous weighing device includes a chute scale, a feed pipe and a discharge pipe. The feed pipe is connected to the feed end of the chute scale, and the discharge pipe is connected to the discharge end of the chute scale. The feed pipe is provided with a feed anti-blocking component for detecting and automatically clearing its own internal blockage, and the discharge pipe is provided with a discharge anti-blocking component for detecting and automatically clearing its own internal blockage.
[0008] By adopting the above technical solution, bulk grain can flow in the feed pipe, chute scale and discharge pipe. The feed anti-blocking component can detect the blockage of the feed pipe and clean the feed pipe after detecting the blockage. The discharge anti-blocking component can detect the blockage of the discharge pipe and clean the discharge pipe after detecting the blockage, so that the measurement accuracy of the chute scale is not easily reduced due to the blockage of the grain transfer pipe.
[0009] Optionally, the feed anti-blocking component includes a detection plate and a pressure sensor. The feed pipe is tilted along the inclination direction of the feed end of the chute scale. The detection plate is hinged to the top of the inner wall of the feed pipe. The pressure sensor is fixed between the detection plate and the inner wall of the feed pipe. The detection plate is tilted along the flow direction of bulk grain toward the direction close to the central axis of the feed pipe. The pressure sensor is used to output a pressure signal.
[0010] By adopting the above technical solution, bulk grain slides in the inclined feed pipe. When the feed pipe is blocked, the bulk grain accumulates and is squeezed on the detection plate, which increases the pressure on the pressure sensor. The pressure signal output by the pressure sensor can be greater than the set value, so that the blockage of the feed pipe can be detected through the detection plate and the pressure sensor.
[0011] Optionally, the feed anti-blocking component also includes a first controller, a first motor and a first material stripper plate. The first controller is electrically connected to the pressure sensor and the first motor respectively. The first motor is fixed to the bottom of the outer wall of the feed pipe. The output shaft of the first motor rotates and penetrates into the feed pipe. The first material stripper plate is fixed to the output shaft of the first motor. The first controller responds to the pressure signal and is used to control the start-up of the first motor.
[0012] By adopting the above technical solution, when the pressure signal is greater than the set value, the first controller controls the first motor to start, the first motor drives the first material shifting plate to rotate, and the first material shifting plate clears the bulk grain in the feed pipe.
[0013] Optionally, the first material shifting plate is arranged along the flow direction of the bulk grain.
[0014] By adopting the above technical solution, the first shifting plate is less likely to hinder the flow of bulk grain, so that the bulk grain is less likely to block the feed pipe due to the first shifting plate.
[0015] Optionally, the discharging anti-blocking component includes a bellows and a tension sensor. The discharging pipe is vertically arranged along the vertical direction of the discharging end of the chute scale. The bellows is connected between the discharging pipe and the discharging end of the chute scale. There are more than two tension sensors arranged around the central axis of the discharging pipe. The tension sensor is located outside the discharging pipe. One end of the tension sensor is fixedly connected to the chute scale, and the other end is fixedly connected to the discharging pipe. The tension sensor is used to output a tension signal.
[0016] By adopting the above technical solution, the discharge pipe and the chute scale are flexibly connected through the bellows. When the discharge pipe is blocked, the overall weight of the discharge pipe will increase, which will increase the tension on the tension sensor and make the tension signal output by the tension sensor greater than the set value. The blockage of the discharge pipe can be detected through the bellows and the tension sensor.
[0017] Optionally, the discharging anti-blocking component also includes a second controller, a second motor and a second material stripper plate. More than two second motors are arranged around the central axis of the discharging pipe. The second motor is fixed on the outer wall of the discharging pipe. The output shaft of the second motor rotates and penetrates into the discharging pipe. More than two second material strippers are provided, and they correspond one-to-one to the second motors. The second material stripper plate is fixed on the output shaft of the second motor. The second controller is electrically connected to all the tension sensors and all the second motors respectively. The second controller responds to the tension signal and is used to control the start-up of all the second motors.
[0018] By adopting the above technical solution, when the tension signal is greater than the set value, the second controller controls all the second motors to start, the second motors drive the second material stripper plates to rotate, and the second material stripper plates clear the discharge pipe.
[0019] Optionally, the second material shifting plate is arranged along the flow direction of the bulk grain.
[0020] By adopting the above technical solution, the second shifting plate is less likely to hinder the flow of bulk grain, so that the bulk grain is less likely to be blocked in the discharge pipe due to the second shifting plate.
[0021] Optionally, a manual valve is provided on the feed pipe, and the manual valve is located on a side of the feed anti-blocking component away from the chute scale.
[0022] By adopting the above technical solution, when the feed anti-blocking component or the discharge anti-blocking component still fails to solve the blockage problem of the feed pipe or the discharge pipe after cleaning, the manual valve is manually closed and the feed pipe, the discharge pipe and the chute scale are cleared by manual intervention.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By providing a detection plate, a pressure sensor, a first controller, a first motor, and a first diverter plate, the feed pipe is facilitated to be automatically detected and cleaned, and the feed pipe is not easily clogged, thereby reducing the measurement accuracy of the chute scale;
[0025] 2. By arranging the bellows, the tension sensor, the second controller, the second motor and the second material-diverting plate, the discharge pipe is easy to be automatically detected and cleaned, so that the discharge pipe is not easily blocked to reduce the measurement accuracy of the chute scale.

The feed pipe 2 is inclined along the inclination direction of the feed end of the chute scale 1, and the discharge pipe 3 is vertically arranged along the vertical direction of the discharge end of the chute scale 1.

[0037] The pressure sensor 42 is arranged in the space between the detection plate 41 and the inner wall of the feed pipe 2, and its two ends are respectively fixedly connected to the detection plate 41 and the inner wall of the feed pipe 2. The pressure sensor 42 is used to output a pressure signal.
[0038] The first motor 44 is fixed to the bottom of the outer wall of the feed pipe 2 , and the output shaft of the first motor 44 rotates and penetrates into the feed pipe 2 .
[0039] The first material shifting plate 45 is in the shape of a rectangular plate, and the middle portion thereof is fixed on the output shaft of the first motor 44 . The first material shifting plate 45 is arranged along the flow direction of the bulk grain.
[0040] The first controller 43 is fixed on the feed pipe 2 and is electrically connected to the pressure sensor 42 and the first motor 44 respectively. The first controller 43 responds to the pressure signal and is used to control the start-up of the first motor 44 .
[0041] Reference Figure 1 A manual valve 6 is provided on the feed pipe 2 , and the manual valve 6 is located on the side of the first motor 44 away from the chute scale 1 .
[0042] During use, the detection plate 41 is squeezed by the bulk grain, increasing the pressure on the pressure sensor 42 until the pressure on the pressure sensor 42 is greater than the set value of the pressure signal. The first controller 43 controls the first motor 44 to start, and the first motor 44 drives the first material shifting plate 45 to rotate. The first material shifting plate 45 shifts the blocked bulk grain to clear the feed pipe 2.
[0043] Reference Figure 1 and Figure 3 The discharging anti-blocking component 5 includes a bellows 51 , a tension sensor 52 , a second controller 53 , a second motor 54 and a second material-diverting plate 55 .
[0044] Reference Figure 1 The bellows 51 is connected between the discharge pipe 3 and the discharge end of the chute scale 1.
[0045] Four tension sensors 52 are arranged around the central axis of the discharge pipe 3 and are respectively located on the four sides of the discharge pipe 3. The tension sensors 52 are arranged vertically and are located outside the discharge pipe 3. The top end of the tension sensor 52 is fixedly connected to the chute scale 1, and the bottom end is fixedly connected to the discharge pipe 3. The tension sensor 52 is used to output a tension signal.

[0049] When in use, the bellows 51 flexibly connects the discharge pipe 3 and the chute scale 1. The bulk grain increases the overall weight of the discharge pipe 3, increasing the tension on the tension sensor 52 until the tension on the tension sensor 52 is greater than the set value of the tension signal. The second controller 53 controls all the second motors 54 to start, and the second motor 54 drives the second material selector plate 55 to rotate.

[0050] The implementation principle of a continuous weighing device for bulk grain transfer in an embodiment of the present application is as follows: when in use, bulk grain flows in the feed pipe 2, the chute scale 1 and the discharge pipe 3. When the bulk grain squeezes the detection plate 41 so that the pressure signal of the pressure sensor 42 is greater than the set value, the first controller 43 controls the first motor 44 to drive the first material shifting plate 45 to shift the bulk grain to clear the feed pipe 2; when the bulk grain increases the weight of the discharge pipe 3 so that the tension signal of the tension sensor 52 is greater than the set value, the second controller 53 controls the second motor 54 to drive the second material shifting plate 55 to shift the bulk grain to clear the discharge pipe 3; when the pressure signal or the tension signal is continuously greater than the set value, the manual valve 6 is closed, and the feed pipe 2, the chute scale 1 and the discharge pipe 3 are manually cleared.
