Description

Technical Field

[0001] This utility model relates to the technical field of rice milling equipment, and in particular to a novel flow balancing device for rice milling machines. Background Technology

[0002] Existing rice milling machine flow balancing devices, such as the automatically adjustable rice milling machine disclosed in utility model patent application number 201520407843.3, mainly include a housing with a feed hopper and a discharge port. Inside the housing is a main shaft with a rice milling roller mounted on it. A cylindrical sieve plate is mounted outside the rice milling roller, forming a cavity for rice milling between the sieve plate and the rice milling roller. The two ends of the cavity are connected to the feed hopper and the discharge port, respectively. A pressure sensor is mounted on the rice milling roller to detect the pressure inside the cavity. The pressure sensor is connected to a control... The discharge flow rate is controlled by a device connected to the outlet. Under normal circumstances, the flow rate inside the cavity and the discharge port are balanced. When the flow rate at the inlet increases or the pressure inside the cavity increases due to other reasons, more broken rice will be produced due to the increased pressure, which increases the broken rice rate and is not conducive to rice whitening. At this time, the pressure sensor detects the increased pressure and sends an electrical signal to the control device. The control device controls the discharge port to increase the discharge flow rate, and the pressure inside the cavity decreases. The control device then controls the discharge port to decrease the discharge flow rate, eventually forming a new balance.

[0003] However, there may still be impurities in brown rice. Most existing flow balancing devices do not screen them, which can easily affect the subsequent rice milling effect. Moreover, most existing rice milling machines have single-stage adjustable feed flow, making it difficult to accurately control the flow. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a new type of rice milling machine flow balancing device that can not only screen impurities such as broken rice and husks in brown rice to avoid affecting the subsequent rice milling effect, but also adjust the brown rice conveying amount in three stages, thereby improving the control accuracy.

[0005] This utility model discloses a novel flow balancing device for a rice milling machine, comprising a connecting mechanism; it also includes a conveying mechanism, a screening mechanism, a drying mechanism, a feeding mechanism, and an adjusting mechanism. The conveying mechanism is installed on the connecting mechanism to convey brown rice, the screening mechanism is installed on the connecting mechanism to screen the brown rice, the drying mechanism is installed on the screening mechanism to dry the brown rice, the feeding mechanism is installed on the conveying mechanism to convey the brown rice, and the adjusting mechanism is installed on the connecting mechanism to adjust the amount of brown rice conveyed. The operator conveys the brown rice into the screening mechanism for screening, filtering out broken rice and husks and other impurities. Simultaneously, the drying mechanism dries the brown rice, increasing its crispness for easier subsequent milling. The conveying mechanism and the feeding mechanism control the amount of brown rice conveyed to improve conveying accuracy, and the adjusting mechanism adjusts the conveying area to balance the flow rate.

[0006] Preferably, the connecting mechanism includes a fixed base, a conveying cylinder, a feeding pipe, and a discharging pipe. The bottom end of the fixed base is fixedly connected to the top end of the rice milling machine. The conveying cylinder is installed on the fixed base. The bottom end of the feeding pipe is connected to the inside of the top end of the conveying cylinder. The discharging pipe is connected to the inside of the conveying cylinder. The screened brown rice enters the conveying cylinder through the feeding pipe. The conveying mechanism drives the brown rice in the conveying cylinder to be discharged into the rice milling machine through the discharging pipe.

[0007] Preferably, the conveying mechanism includes a servo motor, a reducer, a first drive shaft, and spiral blades. The servo motor is mounted on the conveying cylinder, the reducer is mounted on the conveying cylinder, the first drive shaft is rotatably mounted inside the conveying cylinder, and the spiral blades are mounted on the first drive shaft. When the servo motor is started, the servo motor drives the first drive shaft to rotate through the reducer, the first drive shaft drives the spiral blades to rotate, and the spiral blades drive the brown rice in the conveying cylinder to the discharge pipe.

[0008] Preferably, the screening mechanism includes a feeding hopper, a screen plate, and a discharge hopper. The bottom end of the feeding hopper is connected to the top end of the feeding pipe. The screen plate is installed at an incline inside the feeding hopper. The top end of the discharge hopper is connected to the bottom end of the feeding hopper. When the worker feeds brown rice into the feeding hopper, broken rice and husks and other impurities in the brown rice pass through the screen plate and are discharged into the discharge hopper. The whole brown rice passes through the feeding hopper and enters the feeding pipe.

[0009] Preferably, the drying mechanism includes a warm air blower, multiple sets of air supply pipes, and multiple sets of high-pressure nozzles. The bottom of the warm air blower is connected to the top of the feeding pipe. All sets of air supply pipes are installed on the warm air blower, and all sets of high-pressure nozzles are installed inside the feeding pipe and are connected to the inside of the multiple sets of air supply pipes respectively. When the warm air blower is started, it delivers hot air through the multiple sets of air supply pipes to the multiple sets of high-pressure nozzles. The multiple sets of high-pressure nozzles dry the brown rice while blowing on the sieve plate to prevent the brown rice from clogging the sieve plate.

[0010] Preferably, the feeding mechanism includes a second drive shaft, a rotating shaft, three sets of feeding plates, two sets of sprockets, and a chain. The second drive shaft is mounted on a reducer, the rotating shaft is rotatably mounted inside the feeding pipe, all three sets of feeding plates are mounted on the rotating shaft, the two sets of sprockets are respectively mounted on the second drive shaft and the rotating shaft, and the chain drive is installed between the two sets of sprockets. The reducer drives the second drive shaft to rotate, the second drive shaft drives the sprocket connected to it to rotate, the sprocket drives another set of sprockets and the rotating shaft to rotate through the chain, and the rotating shaft drives the three sets of feeding plates to rotate, controlling the speed at which the brown rice falls through the feeding pipe.

[0011] Preferably, the adjustment mechanism includes a pressure sensor, two sets of electric cylinders, a baffle, two sets of guide rods, and two sets of springs. The pressure sensor is installed on the discharge pipe and has a groove. Both sets of electric cylinders are installed on the pressure sensor. The baffle is slidably installed in the groove of the pressure sensor and connected to the top of the two sets of electric cylinders. Both sets of guide rods are installed on the pressure sensor, and the two sets of springs are respectively fitted on the two sets of guide rods. When the pressure sensor detects an increase in pressure in the discharge pipe, it activates the two sets of electric cylinders through an electrical signal. The two sets of electric cylinders push the baffle upward to increase the area through which the brown rice passes. The two sets of guide rods facilitate the vertical lifting and lowering of the baffle. When the pressure sensor detects a continuous increase in pressure, in order to prevent the brown rice from breaking, the pressure sensor reduces the speed of the servo motor through an electrical signal to precisely control the conveying flow rate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff conveys the brown rice to the screening mechanism for screening, filtering out impurities such as broken rice and husks in the brown rice. At the same time, the drying mechanism dries the brown rice, increasing its crispness and facilitating subsequent rice milling. The conveying mechanism and the feeding mechanism control the amount of brown rice conveyed, which facilitates the improvement of conveying accuracy. Meanwhile, the conveying area is adjusted by the adjustment mechanism to balance the flow. Attached Figure Description
