Description

Technical Field

[0001] This invention relates to the field of livestock feeding technology, specifically a device for quantitatively dispensing pig feed. Background Technology

[0002] In large-scale pig farming, pigs at different growth stages, such as piglets, fattening pigs, and pregnant sows, have significantly different feed intake requirements. Insufficient feed intake can lead to slow growth and uneven development, affecting the breeding cycle and the quality of pigs at slaughter. Excessive feed intake can not only waste feed but also easily cause digestive system diseases in pigs, increasing treatment costs.

[0003] Most existing pig feed dispensing devices use a "fixed volume dispensing cylinder" design, which requires manual disassembly and replacement of dispensing cylinders with different inner diameters / heights to adjust the dispensing amount. This operation is cumbersome and cannot quickly adapt to the needs of multiple batches and stages of pigs.

[0004] Therefore, it is necessary to propose a quantitative feeding device for pigs to solve the above problems. Summary of the Invention

[0005] Technical problem to be solved: The purpose of this invention is to provide a quantitative feeding device for pigs, which solves the problem mentioned in the background art that most existing quantitative feeding devices for pigs adopt a "fixed volume quantitative cylinder" design, which requires manual disassembly and replacement of quantitative cylinders with different inner diameters / heights to adjust the feeding amount. This is cumbersome and cannot quickly adapt to the needs of multiple batches and stages of pigs.

[0006] Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: A pig feed quantitative dispensing device includes a quantitative bucket, with fixed frames fixedly installed on both sides of the quantitative bucket, and a control panel fixedly installed on the front side of the quantitative bucket. The lower end of the quantitative bucket is open, and the upper end is connected to an external feed conveying pipe. A weighing pan is located directly below the opening of the quantitative bucket. A quantitative mechanism is provided inside the quantitative bucket, and both the weighing pan and the quantitative mechanism are connected to the control panel. The quantitative mechanism includes a lifting component, a rotating component, and a fixed plate fixedly installed inside the quantitative bucket. The fixed plate divides the quantitative bucket into upper and lower chambers. A rotating disk I and a rotating disk II are rotatably installed vertically in the lower chamber. The rotating disk I is driven by the lifting component, and the rotating component is driven by the rotating disk II. The rotating disc is driven to rotate. The fixed plate, rotating disc I, and rotating disc II are concentrically arranged. A discharge pipe communicating with the upper chamber is fixedly installed at the bottom of the fixed plate, and the lower end of the discharge pipe is in contact with the rotating disc I. Multiple fixed rings II are evenly fixedly installed along the circumference of the bottom of the rotating disc II. A fixed ring I is concentrically fitted inside the fixed ring II. The upper end of the fixed ring I passes through the rotating disc I and is fixedly connected to it. The distance between the discharge pipe and the center of the fixed plate is equal to the distance between the fixed ring I and the center of the fixed plate. A drive ring is concentrically arranged below the rotating disc II. The drive ring is fixedly connected to the metering barrel. The bottom surface of the drive ring has an upwardly recessed arc-shaped groove. A sealing plate that seals the lower end of the fixed ring II is hinged to the bottom. A ball bearing is fixedly installed on the side of the sealing plate near the drive ring. The ball bearing abuts against the bottom surface of the drive ring.

[0007] Preferably, the metering container includes a container body, which is a rotating body with a cylindrical upper end and a conical lower end. A container cover is bolted to the top of the container body, and a feed pipe is fixedly installed on the top of the container cover. The other end of the feed pipe is connected to an external conveying pipeline.

[0008] Preferably, the lifting assembly includes an electric push rod concentrically fixedly mounted on the top of the fixed plate. The output end of the electric push rod passes through the fixed plate and is rotatably connected to the rotating disk I through a bearing. A protective cover is fitted on the outside of the electric push rod, and the protective cover is bolted to the fixed plate.

[0009] Preferably, a fixed cylinder is fitted inside the drive ring, and multiple connecting rods are evenly fixedly installed along the circumference on the outer side of the upper end of the fixed cylinder. The other end of the connecting rods is fixedly connected to the drive ring. A support plate is fixedly installed at the lower end of the fixed cylinder, and multiple support rods are evenly fixedly installed along the circumference at the bottom of the support plate. The other end of the support rods is fixedly connected to the metering bucket.

[0010] Preferably, a ring platform is concentrically fixedly installed on the inner wall of the metering barrel, the rotating disk II is placed on the ring platform, a servo motor is fixedly installed at the bottom of the support plate, and a rotating shaft is concentrically sleeved inside the fixed cylinder.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1: This Example 1 provides a pig feed quantitative dispensing device, which is a direct improvement on existing feed dispensing devices. It has a unique structure. Please refer to [link / reference]. Figure 1-6 As shown, it includes a metering bucket 2, a fixing frame 1, a control panel 3, a weighing pan 4, and a built-in metering mechanism; the fixing frame 1 is a T-shaped steel structure welded from galvanized steel pipes, with a total of 2, which are fixed to both sides of the metering bucket 2 by bolts, and the lower end is fixed to the ground of the breeding farm. Its function is to support the metering bucket 2, ensure its overall stability, and avoid metering deviation caused by vibration during the feeding process.

[0017] The control panel 3 is embedded in the upper middle position of the front side of the metering tank 2. The outer shell is made of ABS material with an IP65 dustproof and waterproof rating. It has a built-in Siemens S7-200 SMART PLC controller and a 10.1-inch touch screen. The control panel 3 is electrically connected to the weighing sensor 45 in the weighing pan 4, the electric push rod 25 of the metering mechanism, and the servo motor 221 through shielded cables. It can realize parameter setting (such as single dispensing amount, alarm number threshold), real-time data display (such as current dispensing amount, residual weight) and equipment status control (such as start / stop, fault alarm).

[0018] The upper end of the metering bucket 2 is connected to an external feed conveying pipe (such as the auger feed conveying pipe of a farm), and the lower end is an open structure. The center of the symmetrical weighing plate 4 is directly below the open end to ensure that the feed falls without deviation. The metering bucket 2 is divided into an "upper chamber (feed temporary storage chamber)" and a "lower chamber (metering execution chamber)" by a fixed plate 24. The core components of the metering mechanism are integrated in the lower chamber.

[0019] The weighing pan 4 is located directly below the opening at the bottom of the metering tank 2, with its central axis coinciding with the central axis of the metering tank 2. The vertical distance from the opening of the metering tank 2 is 300-500mm (which can be adjusted according to the size of the feed particles to avoid splashing when falling). Its function is to receive the feed discharged from the metering tank 2 and to detect the residual weight in real time, providing data support for the metering correction of the control panel 3.

[0020] The metering bucket 2 includes a bucket body 21, a bucket lid 22, and a metering mechanism. The bucket body 21 is a rotating structure, with an upper cylindrical section with an inner diameter of 300-500mm (height 500-800mm, meeting the temporary storage requirements for single feed feeding), and a lower conical section with a cone angle of 60°-90° (height 200-300mm). The conical section design allows the feed to naturally concentrate downwards using gravity, avoiding residue on the bucket wall and solving the problem of easy feed accumulation in existing straight-cylinder buckets. The bucket body 21 is made of 304 food-grade stainless steel with a wall thickness of 3-5mm and a polished surface to reduce feed adhesion.

[0021] The lid 22 is connected to the top of the barrel body 21 by 4-6 circumferentially evenly distributed bolts. A silicone sealing ring (O-shaped cross-section, 8-10mm in diameter) is set between the two to achieve a dustproof seal and prevent external dust from entering the upper chamber and contaminating the feed. The feed pipe 23 is welded to the center of the lid 22. The feed pipe 23 is a stainless steel pipe of DN50-DN80. One end is connected to the lid 22 to the upper chamber, and the other end is connected to the external feed pipeline through a flange to ensure stable feed delivery.

[0022] The metering mechanism includes a lifting assembly, a rotating assembly, a rotating disk I 27, a rotating disk II 210, a fixed plate 24, and a discharge pipe 28. The fixed plate 24 is a circular stainless steel plate (with a diameter consistent with the inner diameter of the cylindrical section of the metering tank 2 and a thickness of 8-12mm). It is fixed to the cylindrical section of the metering tank 2 by circumferential welding, dividing the metering tank 2 into an "upper chamber (above, temporarily storing feed)" and a "lower chamber (below, performing metering)". The central axis of the fixed plate 24 coincides with the central axis of the metering tank 2 to ensure the concentricity of subsequent components.

[0023] The discharge pipe 28 is a stainless steel round pipe (inner diameter 20-40mm, wall thickness 3-5mm), with a total of 1 pipe, which is vertically welded to the bottom of the fixed plate 24. The upper end passes through the fixed plate 24 and connects to the upper chamber, and the lower end is in close contact with the upper surface of the rotating disk I 27 (gap ≤ 0.5mm). The distance between the center of the discharge pipe 28 and the center of the fixed plate 24 (i.e., the "eccentricity") is 80-120mm. This eccentricity is consistent with the eccentricity of the subsequent fixed ring I 29, ensuring that the fixed ring I 29 can accurately align with the discharge pipe 28 when it rotates.

[0024] The lifting assembly is used to drive the rotating disk I 27 to rise and fall, changing the overlap height of the fixed ring I 29 and the fixed ring II 211, thereby adjusting the volume of the metering cylinder. It includes an electric push rod 25 and a protective cover 26. The electric push rod 25 is a high-precision linear electric push rod (such as model DT50, rated thrust 500N, stroke 50-100mm, positioning accuracy ±0.1mm), which is concentrically fixed at the top center of the fixed plate 24 (connected by a flange). The output end passes downward through the center hole of the fixed plate 24 and is rotatably connected to the rotating disk I 27 through a deep groove ball bearing (model 6204). The advantage of the electric push rod 25 is that it has high linear drive precision. The extension and retraction can be precisely controlled through the control panel 3, thereby precisely adjusting the lifting height of the rotating disk I 27 and realizing continuous adjustment of the metering volume (unlike existing fixed volume metering cylinders, no parts need to be replaced).

[0025] The protective cover 26 is a cylindrical stainless steel cover (with an inner diameter 10-20mm larger than the outer diameter of the electric push rod 25), which is fixed to the top of the fixing plate 24 by bolts, completely enclosing the electric push rod 25. The function of the protective cover 26 is to prevent feed dust from the upper chamber from entering the transmission components (such as the motor and lead screw) of the electric push rod 25, avoiding jamming or wear. At the same time, it provides an oil injection hole (located in the upper middle part of the side wall of the protective cover 26) to facilitate the periodic injection of food-grade grease (such as model NSF H1) to ensure the service life of the electric push rod 25.

[0026] The rotating disk I27 is a circular stainless steel plate (diameter 200-300mm, thickness 5-8mm), horizontally set below the fixed plate 24. Its upper surface is in close contact with the lower end of the discharge pipe 28 (to prevent feed from leaking out from the gap). The lower surface is welded with a fixing ring I29 (height 30-50mm), which is connected to the rotating disk II210 through the fixing ring I29. The center hole of the rotating disk I27 is connected to the output end of the electric push rod 25 through a bearing, allowing the rotating disk I27 to rotate synchronously with the rotating disk II210 while being driven to rise and fall by the electric push rod 25.

[0027] The rotating disk II210 is a circular stainless steel plate (with the same diameter as the rotating disk I27 and a thickness of 8-12mm), horizontally positioned below the rotating disk I27 and supported by a ring platform 213 (the ring platform 213 is a ring-shaped stainless steel protrusion welded to the inner wall of the conical section of the metering cylinder 2, with a width of 20-30mm, and the upper surface is milled to ensure horizontality); multiple fixing rings II211 are uniformly welded circumferentially on the lower surface of the rotating disk II210 (2-6 rings are designed according to the dispensing frequency, and 2 rings are preferred in this embodiment). The fixing rings II211 are stainless steel cylinders (with the same inner diameter as the fixing ring I29 and a height of 50-80mm), concentrically nested with the fixing ring I29 to form a "metering cylinder"—the volume of the metering cylinder = πr²h (r is the inner diameter of the fixing ring, and h is the overlap height of the fixing ring I29 and the fixing ring II211). The volume can be continuously adjusted by adjusting h through the lifting component.

[0028] The rotating assembly is used to drive the rotating disk II 210 to rotate, which in turn drives the rotating disk I 27 to rotate synchronously, realizing the docking of the metering cylinder and the discharge pipe 28 and the discharge of feed. It includes a servo motor 221 and a rotating shaft 220. The servo motor 221 is a high-precision servo motor (such as model MG996R, with a rotation angle accuracy of ±0.5° and an output torque of 10 kg·cm), which is fixed to the bottom of the support plate 218 by a bracket. The advantage of the servo motor 221 is that the rotation angle is precise. The rotation angle can be set through the control panel 3 (such as rotating 180° each time, corresponding to 2 fixed rings II 211), ensuring that the fixed ring I 29 can accurately dock with the discharge pipe 28 and avoid misalignment and leakage.

[0029] The drive ring 215 is a ring-shaped stainless steel component, horizontally positioned below the rotating disk II 210, serving to provide a support surface for the sealing structure. The fixed cylinder 216 is a stainless steel cylinder (with an inner diameter 5-10mm larger than the outer diameter of the rotating shaft 220, and a height of 80-120mm), connected to the drive ring 215 via 3-4 circumferentially evenly distributed connecting rods 217 (stainless steel rods, 8-10mm in diameter). The rotating shaft 220 is a stainless steel smooth shaft (15-20mm in diameter, 100-150mm in length), concentrically positioned inside the fixed cylinder 216. Its upper end is connected to the center hole of the rotating disk II 210 via a flat key (for torque transmission), and its lower end is connected to the output shaft of the servo motor 221 via a coupling. A sliding bearing (model SF-1) is installed between the rotating shaft 220 and the fixed cylinder 216 to reduce rotational friction and ensure smooth rotation.

[0030] The support plate 218 is a circular stainless steel plate, welded to the lower end of the fixed cylinder 216. The lower surface of the support plate 218 is welded and fixed to the inner wall of the conical section of the metering cylinder 2 by three circumferentially evenly distributed support rods 219 (stainless steel rods, diameter 12-15mm), forming a stable support structure to ensure the concentricity of the servo motor 221 and the rotating shaft 220. The lower end of each fixed ring II 211 corresponds to a sealing plate 212, which is hinged to the lower edge of the fixed ring II 211 by a hinge (stainless steel material). The function of the sealing plate 212 is to seal the lower end of the metering cylinder to prevent feed from leaking out before reaching the designated position.

[0031] The ball bearing 214 is a wear-resistant steel ball (8-10mm in diameter, chrome-plated, with a hardness of HRC60 or higher), fixed on the side of the sealing plate 212 near the center of the drive ring 215. The ball bearing 214 abuts against the upper surface of the drive ring 215, forming a support point. In the initial state, the ball bearing 214 is located in the planar area of ​​the drive ring 215, and the sealing plate 212 remains horizontal under the support of the ball bearing 214, sealing the lower end of the fixing ring II 211. When the ball bearing 214 rotates with the rotating disk II 210 to the arc-shaped groove of the drive ring 215, the ball bearing 214 falls into the groove, the sealing plate 212 loses its support, and flips downward under the gravity of the feed (opening angle 30°-45°), and the feed is discharged from the metering cylinder. After leaving the arc-shaped groove, the ball bearing 214 returns to the planar area, and the sealing plate 212 resets under the gravity and re-seals.

[0032] The weighing pan 4 includes a feed pan 41, a base 42, a collar I 43, a collar II 44, and a weighing sensor 45. The feed pan 41 is a circular plastic pan (diameter 400-600mm, depth 50-80mm, food-grade PP material) used to receive the feed discharged from the metering tank 2. The upper surface edge of the feed pan 41 is provided with a 50mm high baffle to prevent feed from splashing. The lower end of the base 42 is fixed to the ground with expansion bolts to ensure overall stability. The collar I 43 is a stainless steel cylinder (inner diameter 50-80mm, height 100-150mm) vertically welded to the top center of the base 42. The collar II 44 is a stainless steel cylinder (outer diameter slightly smaller than the inner diameter of the collar I 43, gap 1-2mm, height 120-180mm), which slides inside the collar I 43, and its upper end is welded to the bottom center of the feed pan 41.

[0033] The cooperation between collar I 43 and collar II 44 serves as a guide, ensuring that the feed tray 41 can only move vertically up and down, avoiding weighing errors caused by tilting; the weighing sensor 45 is a high-precision pressure sensor (such as model HBM C16, range 0-50kg, accuracy 0.1%FS), one in total, is set inside collar II 44, the upper end is connected to the bottom of the feed tray 41 by bolts, and the lower end is connected to the top of the base 42 by bolts; the weighing sensor 45 is electrically connected to the control panel 3, transmitting the weight signal to the PLC controller in real time.

[0034] Working principle: The staff first selects the type of pig (such as piglets, fattening pigs, sows) through the touch screen of the control panel 3, or customizes the "target amount per feeding" (such as 100g / feeding for piglets, 500g / feeding for fattening pigs) and the "alarm number threshold" (such as alarming if there is residue after 3 consecutive feedings); the control panel 3 automatically calculates the initial quantitative cylinder volume (i.e., the initial overlap height h0 of the fixed ring I 29 and the fixed ring II 211) according to the set target amount, and controls the extension and retraction of the electric push rod 25 to drive the rotating disk I 27 to rise and fall to the corresponding height, thus completing the quantitative preset.

[0035] Feed is injected into the upper chamber through the external conveying pipe via the feed pipe 23. In the initial state, when one of the fixing rings I 29 is located directly below the discharge pipe 28, the discharge pipe 28 is precisely connected to the metering cylinder. The feed in the upper chamber flows into the metering cylinder through the discharge pipe 28 under the action of gravity. Since the sealing plate 212 is kept in a sealed state under the support of the ball bearing 214, the feed is temporarily stored in the metering cylinder until the metering cylinder is full (the volume is determined by the preset height h0).

[0036] Meanwhile, the ball bearing 214 on another metering cylinder rotates to the arc-shaped groove of the drive ring 215, the sealing plate 212 opens, and the feed in the metering cylinder falls into the feed tray 41 below; after leaving the arc-shaped groove, the sealing plate 212 resets, completing a single metering discharge; then, the control panel 3 controls the servo motor 221 to start, driving the rotating disk II 210 to rotate (e.g., rotating 180° each time), which drives the rotating disk I 27 to rotate synchronously through the fixed ring I 29, so that the other fixed ring I 29 is located directly below the discharge pipe 28 for cyclic feeding; the weighing sensor 45 detects the weight of the feed in the feed tray 41 in real time and transmits the signal to the control panel 3; if the feed is completely consumed, the next feeding will still be performed according to the initial metering cylinder volume; if there is residue, the control panel 3 automatically adjusts the volume of the next metering cylinder so that "next feeding amount = initial capacity - residual amount", and controls the electric push rod 25 to adjust the height of the rotating disk I 27 to achieve residue correction.

[0037] If the weighing sensor 45 detects residue in the feed tray 41 n times consecutively (n = alarm threshold, such as 3 times) (i.e., the pigs have not finished eating the feed multiple times), the control panel 3 determines that the pigs may have health abnormalities (such as loss of appetite or disease), and immediately triggers an audible and visual alarm (the control panel 3 has a built-in buzzer and LED warning light), and displays "Abnormal residue, please check the pigs" on the touch screen, reminding staff to deal with it in time and avoid breeding losses.

[0038] It should be noted that the technical solutions of the pig feed quantitative dispensing device described in the various embodiments of the present invention focus on describing the core structure for achieving the purpose of the invention; although auxiliary or conventional details such as "dustproof design", "lubrication mechanism", "component model", "material selection" and "size parameters" required for the normal operation of the device are not described in detail, it does not mean that the technical solution has not considered such details, nor does it mean that such details are not within the scope of implementation of the technical solution.

[0039] For example, in addition to the silicone sealing ring of the lid 22, a dustproof film is attached to the outside of the touch screen of the control panel 3, and a dustproof skirt (soft PVC material) is set at the lower edge of the conical section of the metering barrel 2 to reduce feed dust from entering the lower chamber; the sliding bearings of the rotating shaft 220 and the fixed cylinder 216, and the lead screw of the electric push rod 25 are regularly injected with food-grade grease, with a lubrication cycle of once a month, which is replenished through the oil injection hole of the protective cover 26 and the oil injection nozzle of the fixed cylinder 216; the parts in contact with the feed (barrel body 21, lid 22, discharge pipe 28, rotating disc I / II, fixed ring I / II, sealing plate 212, feed tray 41) are all made of food-grade materials and comply with GB4806.1-2016 "National Food Safety Standard General Safety Requirements for Food Contact Materials and Products".

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
