Abstract
Description
Technical Field
[0001] This application relates to the field of flow meters, and particularly to a double impact plate flow meter. Background Art
[0002] The grain flow meter measures the weight of grains in real time through a weighing sensor, and calculates the grain flow rate by combining the speed information of the conveying mechanism. Specifically, when grains flow through the weighing sensor via the conveying mechanism, the weighing sensor detects the weight change of the grains and transmits the signal to the control system. The control system calculates the grain flow rate based on the signal of the weighing sensor and the speed information of the conveying mechanism, and displays the result on the display screen.
[0003] To ensure the accuracy of measurement, the height of the notch through which the grains pass is limited within a certain range. An overly high or wide notch will seriously affect the measurement accuracy. However, such a narrow notch may be blocked by grains, thus affecting the operation of the flow meter.
[0004] In response to this, we propose a double impact plate flow meter to solve the above problems. Utility Model Content
[0005] The purpose of this application is to quickly dredge the notch when the flow meter is blocked. Compared with the prior art, a double impact plate flow meter is provided, which includes a box body. An inlet chute is arranged at the upper end of the box body, and a stirring component is installed on the inner wall of the inlet chute. The stirring component includes a flow dividing plate fixedly connected to the inner wall of the inlet chute. A support block is fixedly connected to the lower wall of the flow dividing plate. The lower end of the support block is connected to a flow dividing pipe through a plurality of hydraulic rods. The lower end of the flow dividing pipe is fixedly connected to a disturbance pipe. A pair of measurement components corresponding to the front and rear side walls of the flow dividing plate are installed on the inner wall of the box body. The hydraulic rods are electrically connected to an external controller. By arranging measurement components on both sides of the flow dividing plate, the measurement efficiency of grains can be effectively improved, and the probability of blockage can be reduced. When the flow meter is blocked, the hydraulic rods are used to push the flow dividing pipe to drive the disturbance pipe to insert into the grains to disturb and dredge the grains, realizing the timely dredging of the flow meter and improving the practicability of the device.
[0006] Furthermore, the measurement component includes a rotating shaft. One end of the rotating shaft is rotatably connected to the inner wall of the box body, and the other end penetrates through the side wall of the box body and is fixedly connected to a torque measuring instrument. The torque measuring instrument is fixedly connected to the outer wall of the box body through a fixing frame. An impact plate is fixedly connected to the upper end of the rotating shaft. The impact plate is inclined inward. A dust-proof shell corresponding to the position of the fixing frame is installed on the side wall of the box body. The impact of grains on the impact plate generates torque, which is transmitted to the torque measuring instrument through the rotating shaft. The torque measuring instrument accurately measures the grain flow rate passing through according to the built-in calculation model.
[0007] Further, a buffer cavity is provided inside the support block. The buffer cavity is communicated with an intake pipe which penetrates through the side wall of the box body and extends to the outside thereof. One end of the intake pipe far from the support block is fixedly connected with an air pump, and the air pump is fixedly connected to the side wall of the box body. A gas distribution cavity is provided inside the flow dividing pipe. The gas distribution cavity is communicated with the buffer cavity through a guide pipe, and a disturbance pipe is communicated with the gas distribution cavity. The air pump is used to pump gas into the flow dividing pipe through the intake pipe. The flow dividing pipe conveys the gas to the disturbance pipe, so that the gas can enter the blocked grains through the disturbance pipe, effectively dredging the grains. The hollow disturbance pipe can effectively reduce the compression on the grains and avoid damaging the grains.
[0008] Further, an expansion bladder is fixedly connected to the lower bottom wall of the disturbance pipe. The expansion bladder is recessed towards the side close to the support block. The gas is pumped into the disturbance pipe to cause the expansion bladder to bulge outwards, flexibly squeezing the grains and realizing effective dredging of the grains without damaging them.
[0009] Further, the distance between the lower edge of the flow dividing plate and the impact plate is 5 - 10 cm, and the inclination angle of the impact plate is 27 - 30 degrees.
[0010] Compared with the prior art, the advantages of this application are as follows:
[0011] Measurement components are arranged on both sides of the flow dividing plate, which can effectively improve the measurement efficiency of grains and reduce the probability of blockage. When the flow scale is blocked, the hydraulic rod is used to push the flow dividing pipe to drive the disturbance pipe to insert into the grains, disturbing and dredging the grains, realizing timely dredging of the flow scale and improving the practicability of the device.
