Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice production technology, and more specifically to a quantitative feeding and weighing device for a rice production line. Background Technology
[0002] With population growth and increasing food demand, rice processing enterprises are transforming towards large-scale and automated operations. Traditional manual weighing methods are inefficient and prone to errors, requiring efficient and precise mechanical equipment. Quantitative feeding and weighing equipment for rice production lines has emerged to meet this need. This equipment automates weighing and feedback control to replace manual operation, enabling rapid and continuous feeding, reducing downtime, and meeting the high-efficiency requirements of rice production lines.
[0003] However, in the actual use of existing weighing equipment, in order to strictly ensure the accuracy of the conveyed weight, the size of the conveying port needs to be strictly controlled and kept relatively small. This can easily lead to blockages during the material conveying process.
[0004] In addition, the existing device adopts a box-shaped design. This design structure causes rice to gradually accumulate at the corners when flowing or stored in the device, making it impossible to completely discharge, resulting in a discrepancy between the discharged weight and the weighed weight.
[0005] To address the aforementioned problems, this application provides a quantitative feeding and weighing device for a rice production line. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quantitative feeding and weighing device for a rice production line to solve the problems existing in the background art.
[0007] This utility model provides the following technical solution: a quantitative feeding and weighing device for a rice production line, including a feeding component and a weighing component disposed below the feeding component, a conveying component installed on the feeding component, and a discharging component and an auxiliary pushing component installed on the weighing component;
[0008] Preferably, the feeding assembly includes a positioning plate, support rods, a conical feeding hopper, a first feeding hopper, a fixing frame, and a conical conveying roller. Support rods are fixedly installed at the four corners of the positioning plate. The conical feeding hopper is positioned directly below the positioning plate. The first feeding hopper is fixedly installed on the upper left side of the conical feeding hopper. The fixing frame is fixedly installed between the conical feeding hopper and the positioning plate. The conical conveying roller is positioned to fit snugly against the inner cavity of the conical feeding hopper. When rice is poured into the conical feeding hopper through the first feeding hopper, the conveying assembly drives the conical conveying roller to rotate, evenly conveying the rice to the bottom.
[0009] Preferably, the conveying assembly includes a sliding column, a sliding sleeve, a limiting member, a first gear, a second gear, a convex ring, a rotary motor, and a first telescopic motor. The sliding column is fixedly sleeved on the top shaft of the conical conveying roller. The first telescopic motor is fixedly installed above the positioning plate, and its telescopic shaft rotatably sleeves the sliding column. The sliding sleeve vertically slides between the sliding column and the positioning plate. The first gear is fixedly sleeved on the sliding sleeve and meshes with the first gear. The rotary motor is fixedly installed on the top of the positioning plate, and its drive shaft movably passes through the positioning plate and is fixedly sleeved on the second gear. The convex ring is fixedly sleeved on the lower end of the rotary motor drive shaft and the lower side of the sliding sleeve. The limiting member is set between the rotary motor drive shaft and the sliding sleeve and is rotatably connected to it through the convex ring. At this time, the rotary motor drive shaft drives the second gear to rotate. Under the limiting action and meshing action of the limiting member, the first gear and the sliding sleeve fixedly sleeved to it rotate. At the same time, the sliding column vertically engaged with the sliding sleeve is driven to rotate. The conical conveying roller is driven to rotate by the sliding column. At the same time, the sliding column and the conical conveying roller can be extended and retracted by the telescopic shaft of the first telescopic motor, thereby adjusting the gap between the conical conveying roller and the inner wall of the conical feeding barrel.
[0010] Preferably, the weighing assembly includes an inclined-bottom weighing box, a weighing device, a second feed hopper, and a solenoid valve. The inclined-bottom weighing box is fixedly installed on the weighing device. A solenoid valve is installed at the feed inlet at the top of the inclined-bottom weighing box. The second feed hopper is located directly above the solenoid valve and is fixedly installed on the inclined-bottom weighing box. Rice enters the inclined-bottom weighing box through the solenoid valve. After the weighing device detects that the specified weight has been reached, the solenoid valve closes.
[0011] Preferably, the discharge assembly includes a limiting frame, a baffle, a second telescopic motor, and a discharge hopper. The limiting frame is fixedly installed on the right side of the inclined-bottom weighing box. The baffle is located at the discharge port on the right side of the inclined-bottom weighing box and is slidably connected between the inclined-bottom weighing box and the limiting frame. The second telescopic motor is vertically fixedly installed on the top left side of the inclined-bottom weighing box. The telescopic shaft of the second telescopic motor is fixedly connected to the baffle. The discharge hopper is fixedly installed on the lower right side of the inclined-bottom weighing box. At this time, the telescopic shaft of the second telescopic motor retracts, causing the baffle to rise along the slide rail. The rice is discharged through the discharge port on the right side of the inclined-bottom weighing box and then flows to the next process through the discharge hopper.
[0012] Preferably, the auxiliary pushing assembly includes a pushing plate, a transmission column, a pushing frame, and a third telescopic motor. The pushing plate has vertically oriented transmission columns fixedly installed at its four corners. The end of the transmission column away from the pushing plate moves through the inclined bottom weighing box and is fixedly installed on the pushing frame. The third telescopic motor is fixedly installed at the bottom of the inclined bottom weighing box. The telescopic shaft of the third telescopic motor is fixedly connected to the pushing frame. During the discharge process, the third telescopic motor reciprocates to drive the pushing frame and the pushing plate fixedly connected to it through the transmission column to reciprocate to lift and lower, quickly pushing and discharging the rice accumulated in the corner of the inclined bottom weighing box.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] The telescopic and adjustable design of the feeding assembly allows the device to quickly clear blockages by adjusting the gap between the feeding roller and the conical feeding hopper when the feeding hopper is blocked. At the same time, the design of the auxiliary pushing assembly can quickly discharge rice accumulated at the corner of the weighing box, avoiding discrepancies between the output weight and the weighed weight, and improving the metering accuracy and reliability of the device.

[0027] The working principle of this utility model is as follows: When using this device, rice is poured into the conical feeding bucket 103 through the first feeding hopper 104. The drive shaft of the rotary motor 207 drives the second gear 205 to rotate. Under the limiting action and meshing action of the limiting member 203, the first gear 204 and the sliding sleeve 202 fixedly connected to it rotate. At the same time, the sliding column 201, which is vertically engaged with the sliding sleeve 202, is driven to rotate. The conical conveying roller 106 is driven to rotate by the sliding column 201, so that the rice is evenly conveyed to the bottom and falls into the second feeding hopper 303. If a blockage occurs during the conveying process, the sliding column 201 and the conical conveying roller 106 can be extended or retracted by the extension shaft of the first telescopic motor 208, thereby adjusting the width. The gap between the conical conveying roller 106 and the inner wall of the conical feeding bucket 103 quickly clears the blockage. At this time, the rice enters the inclined bottom weighing box 301 through the solenoid valve 304. After the weighing device 302 detects that the specified weight has been reached, the solenoid valve 304 closes. The telescopic shaft of the second telescopic motor 403 retracts, driving the baffle 402 to rise along the slide rail. The rice is discharged through the discharge port on the right side of the inclined bottom weighing box 301, and then flows to the next process through the discharge hopper 404. During the discharge process, the third telescopic motor 504 reciprocates, driving the pusher 503 and the pusher plate 501, which is fixedly connected to it through the transmission column 502, to rise and fall repeatedly, quickly pushing and dispersing the rice accumulated in the corner of the inclined bottom weighing box 301.
