Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to feed weighing and proportioning devices. Background Technology

[0002] With the development of the feed industry, the control of feed weight has become increasingly stringent, requiring precise control of the proportion of each raw material. Modern feed production is developing towards large-scale and automated production, demanding that weighing and proportioning devices can be linked with other production equipment to achieve automated batching. Therefore, the device needs to have a reliable control system, such as sequential scanning and production control through electronic systems and terminal control systems, and can adopt fully automatic, semi-automatic, or manual control methods.

[0003] In existing technologies, different feeds are typically fed, measured, and discharged separately during metering and proportioning. In these processes, the discharge mechanism needs to be operated each time. Commonly used discharge mechanisms, such as flap or tipper types, use hydraulic cylinders to move the baffle or tipper downwards to open the discharge port, allowing the material to be discharged from the metering mechanism into subsequent mixing or packaging equipment, and then reset. This process wastes a lot of feeding time, resulting in low weighing and proportioning efficiency. Utility Model Content

[0004] This invention addresses the technical problem of low weighing and proportioning efficiency in existing technologies due to the significant waste of feeding time during the feeding process. It provides a feed weighing and proportioning device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feed weighing and proportioning device, comprising: a feed cylinder, the feed cylinder being placed at the lower part of a metering mechanism, the metering mechanism being fixed by a metering bracket, a conveying device capable of transporting the feed cylinder to the lower part of the metering mechanism, a feeding mechanism being provided at the upper part of the metering mechanism, the feeding mechanism being capable of discharging different feeds into the metering mechanism, the metering mechanism including discs, two discs being connected to the metering brackets on both sides, concentric arc plates being connected to the two discs on both sides, an input shaft being rotatably connected to the discs and the metering brackets, the input shaft being connected to a servo motor via a self-locking mechanism. The machine output shaft is connected, and the input shaft is connected to the polygonal cylinder inside the two discs. A slide rod is slidably connected to the side wall formed by each side of the polygonal cylinder. The end of the slide rod inside the polygonal cylinder is connected to a limit block, and the other end of the slide rod is connected to a hopper. A weight sensor is connected to the outer surface of the side wall formed by each side of the polygonal cylinder. When the hopper is located at the bottom of the feeding mechanism, it is supported by the weight sensor. The lower end of the arc plate is connected to a downwardly inclined tangential guide plate. The weight sensor can send the weight signal of the hopper to the controller. The controller can control the opening and stopping of the feeding mechanism and the rotation angle of the servo motor.

[0006] Preferably, the feeding mechanism includes multiple screw conveyors, which are fixedly installed externally. Each screw conveyor can transport different feeds. The output ends of all screw conveyors are connected to the discharge cone, which can discharge feed to the upper hopper. The controller can control the operation of the corresponding screw conveyor.

[0007] Preferably, the conveying device includes a conveying bracket, a rubber roller shaft end is rotatably connected inside the conveying bracket, a metering bracket is connected to the conveying bracket, adjacent rubber roller shaft ends are connected by chain drive, and one rubber roller shaft end is connected to a power source.

[0008] Preferably, a laser transmitter and a receiver are respectively connected to the end surfaces of the metering brackets on both sides along the conveying direction of the conveying device. The receiver can send whether a laser signal is received to the controller, and the controller can control whether the conveying device is operating.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. Different feeds are sequentially fed into the hoppers via the feeding mechanism. When the weight sensor detects that the weight of a feed has reached the specified value, the controller controls the feeding mechanism to switch feeding methods to complete the mixing ratio of different feeds. When feeding is completed and the feed is discharged, the controller controls the servo motor to rotate at a specified angle so that the next hopper is turned to the feeding mechanism. The hopper that has completed feeding is then discharged. In this way, the feeding and discharging processes do not affect each other, greatly improving the efficiency of weighing and mixing.

[0010] 2. By determining whether the laser signal is blocked by the material cylinder, the conveying device is controlled to continue conveying, thus achieving precise positioning of the material cylinder without manual intervention. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0015] The present invention will now be described in detail with reference to the accompanying drawings.

[0016] The following is in conjunction with the appendix Figure 1-3 The feed weighing and proportioning device of this embodiment includes: a feed cylinder 1, which is placed at the lower part of a metering mechanism 2. The metering mechanism 2 is fixed by a metering bracket 3. A conveying device 5 can transport the feed cylinder 1 to the lower part of the metering mechanism 2. A feeding mechanism 4 is provided at the upper part of the metering mechanism 2, which can discharge different feeds into the metering mechanism 2. The metering mechanism 2 includes two discs 21, which are connected to the metering brackets 3 on both sides. Concentric arc plates 22 are connected to both sides of the two discs 21. An input shaft 23 is rotatably connected to the discs 21 and the metering brackets 3. The input shaft 23 is connected to the output shaft of a servo motor through a self-locking mechanism. Two circular discs 21 contain polygonal cylinders 24 connected together. Each side of the polygonal cylinder 24 has a sliding rod 25 slidably connected to its sidewall. The end of the sliding rod 25 inside the polygonal cylinder 24 is connected to a limit block 26, and the other end of the sliding rod 25 is connected to a hopper 27. Each side of the polygonal cylinder 24 has a weight sensor 28 connected to its outer surface. When the hopper 27 is located under the feeding mechanism 4, it is supported by the weight sensor 28. The lower end of the arc plate 22 is connected to a downwardly inclined and tangential guide plate 29. The weight sensor 28 can send the weight signal of the hopper 27 to the controller, which can control the opening and stopping of the feeding mechanism 4 and the rotation angle of the servo motor.

[0017] In operation, the hopper 27, located below the feeding mechanism 4, is supported by the weight sensor 28. The servo motor outputs power to the input shaft 23 via a self-locking mechanism (which can be a worm gear mechanism). The input shaft 23, through the polygonal cylinder 24 and the slide bar 25, rotates the hopper 27 to the lower part of the feeding mechanism 4. At this point, the hopper 27 is completely supported by the weight sensor 28. The weight sensor 28 detects the weight of the feed inside the hopper 27, and the feeding mechanism 4 sequentially discharges different feeds into the hopper 27. When the weight sensor 28 detects that the weight of a feed has reached a specified level, the controller controls the feeding mechanism 4 to switch the type of feed for dispensing. This process completes the mixing of different feeds. When dispensing is complete, the controller controls the servo motor to rotate by a specified angle, causing the next hopper 27 to rotate to the lower part of the feeding mechanism 4. The previously filled hopper 27 then rotates to the lower part for dispensing. Thus, the feeding and dispensing processes do not interfere with each other, greatly improving weighing and mixing efficiency.

[0018] The feeding mechanism 4 includes multiple screw conveyors 41, which are fixedly installed externally. Each screw conveyor 41 can transport different feeds. The output ends of all screw conveyors 41 are connected to the discharge cone 42, which can discharge feed to the upper hopper 27. The controller can control the operation of the corresponding screw conveyor 41.

[0019] The controller controls the operation of the corresponding screw conveyor 41 to transport the feed into the discharge cone 42, and the discharge cone 42 guides the feed into the hopper 27.

[0020] The conveying device 5 includes a conveying bracket 51, with the shaft end of a rubber roller 52 rotatably connected inside the conveying bracket 51. The metering bracket 3 is connected to the conveying bracket 51, and the shaft ends of adjacent rubber rollers 52 are connected through chain drive. The shaft end of one rubber roller 52 is connected to a power source.

[0021] The power source drives all the rubber rollers 52 to operate at the same speed and synchronously through chain transmission, so as to smoothly transport the material cylinder 1.

[0022] Laser emitters 6 and receivers 7 are respectively connected to the end surfaces of the metering brackets 3 on both sides along the conveying direction of the conveying device 5. The receivers 7 can send whether a laser signal is received to the controller, and the controller can control whether the conveying device 5 is operating.

[0023] By determining whether the laser signal is blocked by the material cylinder 1, the conveying device 5 is controlled to continue conveying, thus achieving precise positioning of the material cylinder 1 without manual intervention.
