Description

Technical Field

[0001] The present application relates to the field of flow scales, and in particular to a weighing structure of an online grain metering device. Background Art

[0002] A grain flow scale uses load cells to measure the weight of grain in real time and, combined with information about the conveyor's speed, calculates the grain flow rate. Specifically, as grain flows through the conveyor, the load cells detect changes in weight and transmit a signal to the control system. The control system calculates the grain flow rate based on the load cell signal and the conveyor's speed information, and displays the result on a display.

[0003] When the moisture content of rice is high, the adhesion between rice grains is greater, and they are easy to stick together under greater pressure, blocking the flow scale and seriously affecting work efficiency.

[0004] To this end, we proposed a weighing structure of an online grain metering equipment to solve the above problems. Utility Model Content

[0005] The purpose of this application is to avoid the blockage of the feed port. Compared with the existing technology, a weighing structure of an online grain metering equipment is provided, including a box body, a feed assembly is arranged at the upper end of the box body, the feed assembly includes a pair of side plates, one end of the pair of side plates is fixedly connected by a guide plate, and the other end of the pair of side plates is fixedly connected by a baffle, a guide assembly corresponding to the position of the guide plate is arranged between the pair of side plates, and a weighing assembly corresponding to the bottom end position of the guide assembly is arranged on the inner wall of the box. When the moisture content of the rice is too high and the degree of adhesion is large, it is easy to cause the equipment to be blocked. At this time, the guide assembly is used to make the rice actively flow, thereby improving the fluidity of the rice and allowing the blocked rice to pass smoothly.

[0006] Furthermore, the weighing assembly includes a rotating shaft, one end of which is rotatably connected to the inner wall of the box through a base, and the other end of the rotating shaft is fixedly connected to a torque sensor, which is fixedly connected to the side wall of the box through a fixing bracket. A punch plate is fixedly connected to the upper wall of the rotating shaft, and the impact of rice on the punch plate drives the rotating shaft to rotate and generate torque. The torque of the rotating shaft is detected in conjunction with the torque sensor, thereby measuring the rice. The base allows the rotating shaft to rotate, and the fixing bracket improves the stability of the torque sensor.

[0007] Furthermore, side plates are installed on both side walls of the punching plate, which can limit the spreading range of the rice and prevent the rice from falling to other places.

[0008] Furthermore, the guide assembly includes a support plate, which is fixedly connected between a pair of side plates and corresponds to the position of the guide plate. A pair of rollers corresponding to the upper and lower ends of the support plates are rotatably connected between the side plates. A motor corresponding to the position of the roller is provided on the outer wall of the side plate. The output end of the motor passes through the side plate and is fixedly connected to the roller. A guide belt is wrapped around the outside of the roller. The motor drives the roller to rotate, thereby causing the guide belt to rotate, driving the blocked rice to flow, and preventing the rice from blocking the equipment. The support plate can provide sufficient support force for the guide belt.

[0009] Furthermore, the guide belt is attached to the upper wall of the support plate, a working groove is left between the support plate and the guide plate, and the upper end roller is arranged in the working groove.

[0010] Furthermore, a guard plate is installed on the upper wall of the guide plate, and the surface of the guard plate is polished to obtain a smooth surface. The guard plate can protect the outer wall of the guide plate and prevent it from being damaged by long-term friction caused by the flow of rice.

[0011] Furthermore, the distance between the lower end of the guide belt and the punching plate is 5-10 cm, and the inclination angle of the weighing component is 27-30 degrees.

[0012] Compared with the existing technology, the advantages of this application are:

[0013] 1. When the moisture content of rice is too high and the degree of adhesion is large, it is easy to cause equipment blockage. At this time, the guide component is used to make the rice flow actively, which improves the fluidity of the rice and allows the blocked rice to pass smoothly.

[0014] 2. Use the motor to drive the roller to rotate, so that the guide belt rotates, driving the blocked rice to flow, and preventing the rice from blocking the equipment. The support plate can provide sufficient support force for the guide belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Specifically, when the moisture content of rice is too high and the degree of adhesion is large, it is easy to cause equipment blockage.
