Description

Technical Field

[0001] The present invention particularly relates to a poultry feeding device, a calibration method thereof, and a feeding method. Background Art

[0002] Poultry farming refers to the artificial breeding of birds, such as chickens, ducks, and geese, for the purpose of obtaining feathers, eggs, and meat. Poultry farming has become an important industry in modern society. Its production process involves not only breeding technology, but also breed selection, disease prevention and control, feed nutrition, and environmental management. Among them, multi-layer poultry cage technology can greatly improve breeding efficiency and intensive level. Therefore, poultry production enterprises at home and abroad mostly use multi-layer poultry cage technology for poultry feeding equipment, thereby significantly improving feeding efficiency and reducing feeding labor intensity in production applications. At the same time, it reduces human-poultry contact, which is beneficial to poultry growth.

[0003] However, in actual use, the existing multi-layer poultry cage feeding equipment is unable to reasonably provide the feeding amount of feed and nutrients according to the actual needs of poultry in different cages, resulting in the inability to quantify the feeding amount and poor feeding accuracy, which needs to be improved.

[0004] Therefore, it is necessary to invent a poultry feeding device and a calibration method and a feeding method thereof to solve the above problems. Summary of the Invention

[0005] (1) Purpose of the invention

[0006] The object of the present invention is to provide a poultry feeding device and a calibration method thereof, and a feeding method. The present invention calibrates feed, nutrients and a feeding motor. When the feeding cart moves on the track, it can feed according to the pre-set feeding amount. When the Hall proximity switch detects the detection magnet on the segment plate, the PLC controller will identify and determine the number of the detection magnet, read the feed feeding amount and the nutrient feeding amount pre-entered on the feeding section, and control the feeding motor to discharge the corresponding feeding amount, thereby reasonably providing the feed and nutrient feeding amount required by the poultry in the feeding section, the feeding amount is quantified, and the feeding accuracy is high; furthermore, when the feeding cart changes to different types of feed or nutrients, it only needs to input the corresponding density on the central control screen to directly obtain the number of rotations of the auger that conveys the feed or nutrients, thereby controlling the feeding amount, so that the feeding cart can be put into use as soon as possible and can adapt to different feeds or nutrients to solve the above-mentioned shortcomings in the technology.

[0007] (2) Technical solution

[0008] To achieve the above objectives, the present invention provides the following technical solutions: a poultry feeding device comprising a frame, the frame being in a stepped shape, with breeding cages mounted on each layer of the frame, and further comprising: a bracket disposed on the top of the uppermost layer of the frame, a track laid on the top of the bracket, and a feeding assembly movable along the top of the track for feeding the poultry in the breeding cages on each layer;

[0009] One end of the bracket is provided with a calibration component, which can calibrate the feeding amount of feed and nutrients required by the poultry in each layer of breeding cages.

[0010] Preferably, the distance between the bottom of the track and the top of the uppermost breeding cage is set to 3-10 cm, and the track is set to a hot-dip galvanized round tube;

[0011] Among them, the track is divided into a feeding area and a charging area,

[0012] The feeding area is located above the breeding cage.

[0013] The charging area is located at the end of the track and has a length of ≤1m, and is used for stopping or charging the traveling components.

The feed delivery pipes are perpendicular to the length of the track, and the drop pipe is arranged below one end of the feed delivery pipe away from the main silo, and is vertical or inclined as a whole.

[0016] Among them, an auger is installed inside each nutrient delivery pipe and each feed delivery pipe, and a delivery motor for controlling the rotation of the auger is installed at the end of the nutrient delivery pipe and the feed delivery pipe. A Hall sensor is installed at the tail of each delivery motor to obtain the real-time speed of the delivery motor connected to it.

Specifically, after the Hall sensor obtains the speed of the feeding motor, it can transmit it to the PWM speed regulator, and the speed of the feeding motor can be set by the PWM speed regulator.

[0020] The PWM speed regulator can also control the travel motor by setting the travel PWM value, so that the travel component drives the feeding vehicle to move at a constant speed along the length of the track. The specific steps are:

[0021] a. Set the feeding trolley's travel speed through the central control screen so that the feeding trolley can travel under full load. The PLC controller measures the travel PWM value at this travel speed as the initial travel value and records it in the PLC controller.

[0022] b. After the initial setting of the walking PWM value is completed, when the feeding cart performs the feeding task, the walking PWM value is automatically called, and the walking PWM speed regulator is used to control the feeding cart to move at the specified speed;

[0087] A544. Repeat steps A541-A543 to complete the setting of the feeding speed of each feeding section on each layer of the breeding cage, so that the feeding motor can discharge the corresponding feeding amount.

[0088] Compared with the prior art, the beneficial effects of the above technical solution of the present invention are:

[0089] 1. The present invention calibrates feed, nutrients and a feeding motor. When the feeding cart moves on the track, it can feed according to a pre-set feeding amount. When the Hall proximity switch detects the detection magnet on the segment plate, the PLC controller identifies and determines the number of the detection magnet, reads the feed feeding amount and nutrient feeding amount pre-entered on the feeding section, and controls the feeding motor to discharge the corresponding feeding amount for the poultry in the feeding section.

[0104] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0105] The present invention provides Figure 1-6 The poultry feeding device shown comprises a frame (1), wherein the frame (1) is in a stepped shape, and each layer of the frame (1) is equipped with a breeding cage (3), and further comprises:

[0106] A bracket (2) arranged on the top of the uppermost layer of the skeleton (1), a track (4) laid on the top of the bracket (2), and a feeding assembly (5) movable along the top of the track (4) for feeding the poultry in the breeding cages (3) on each layer;

[0107] One end of the bracket (2) is provided with a calibration component (6) capable of calibrating the feeding amount of feed and nutrients required by the poultry in each layer of the breeding cage (3).

[0108] In one embodiment, the distance between the bottom of the track (4) and the top of the uppermost breeding cage (3) is set to 3-10 cm, and the track (4) is set to a hot-dip galvanized round tube, wherein the track (4) is divided into a feeding area (41) and a charging area (42), wherein the feeding area (41) is located above the breeding cage (3), and the charging area (42) is located at the end of the track (4), and the length is ≤1m, ensuring that the track (4) does not undergo plastic deformation under pressure for a long time, and is used for stopping or charging the walking component (58), and the track (4) is set on the top of the skeleton (1). At the same time, the structure can rely on the existing skeleton (1) to quickly complete the installation and laying, and can effectively ensure the consistency of the relative positions of the track (4), the skeleton (1), and the feeding trough, providing a guarantee for the smooth operation and accurate feeding of the walking component (58) on the skeleton (1), while not occupying the aisle space, not damaging the ground structure of the breeding house, and facilitating daily breeding management.

[0109] In one embodiment, the feeding assembly (5) includes a feeding cart (51) arranged above the track (4), the feeding cart (51) including a main silo (52) for containing feed, a plurality of auxiliary silos (53) installed on both sides of the main silo (52) for containing nutrients, a nutrient delivery pipe (54) arranged below the auxiliary silo (53) and connecting the auxiliary silos (53) on the same side, a feed delivery pipe (55) located below the nutrient delivery pipe (54) and connecting the nutrient delivery pipe (54) and the main silo (52), and a drop pipe (56) arranged at the end of the feed delivery pipe (55) and connected to the feed delivery pipe (55);

[0110] The auxiliary material bins (53) on both sides of the main material bin (52) are evenly spaced and arranged along the length direction of the track (4); the two nutrient delivery pipes (54) are laid along the length direction of the track (4); and a plurality of feed delivery pipes (55) are provided on both sides of the main material bin (52); the feed delivery pipes (55) are perpendicular to the length direction of the track (4); and the drop pipe (56) is provided below one end of the feed delivery pipe (55) away from the main material bin (52), and the whole is vertical or inclined.

[0111] Wherein, each nutrient delivery pipe (54) and each feed delivery pipe (55) is internally installed with an auger, and the ends of the nutrient delivery pipe (54) and the feed delivery pipe (55) are both installed with a delivery motor (57) for controlling the rotation of the auger, and the tail of each delivery motor (57) is installed with a Hall sensor for obtaining the real-time rotation speed of the delivery motor (57) connected thereto;

[0112] The auger is configured as a solid nylon auger, the diameter of the spiral blade is 47 mm, the clearance between the nutrient delivery pipe (54) and the inner wall of the feed delivery pipe (55) is 0.5 mm, and the nutrient delivery pipe (54) and the feed delivery pipe (55) are configured as seamless stainless steel pipes with an inner diameter of 48 mm, which can improve the feeding accuracy and uniformity and reduce the feed powdering rate;

[0113] The pitch of the auger located inside the nutrient delivery pipe (54) is set to 5-10 mm, and the pitch of the auger located inside the feed delivery pipe (55) is set to 15-20 mm;

[0114] The feeding motor (57) is configured as a DC reduction motor, and the speed of the feeding motor (57) at the end of the nutrient feeding pipe (54) is configured to be 1-10 r / min, and the speed of the feeding motor (57) at the end of the feed feeding pipe (55) is configured to be 10-100 r / min.

[0115] In this embodiment, the main material bin (52), the auxiliary material bin (53), the nutrient delivery pipe (54), the feed delivery pipe (55), and the drop pipe (56) are all made of 304 stainless steel. While maintaining sufficient structural strength, the deadweight can be significantly reduced. The structure has good structural strength and weather resistance, and the carrying capacity of the feeding vehicle (51) can be improved. At the same time, the power consumed by the delivery motor (57) is relatively small, which can reduce energy consumption.

[0116] In one embodiment, the feeding assembly (5) further comprises a walking assembly (58) disposed below the main silo (52) and mounted on the track (4);

[0117] The walking assembly (58) comprises a control box (581) mounted on the bottom of the feeding cart (51), wheels (582) mounted on the bottom of the control box (581), a counter (583) arranged at the bottom of the control box (581), a PWM speed regulator (584) mounted on the control box (581), a walking motor located at the bottom of the control box (581), an output end of the walking motor being connected to two wheels (582) located outside the control box (581) via a coupling, a central control screen (585) located on the side of the control box (581), and a PLC controller mounted on the control box (581) and capable of controlling the central control screen (585);

[0118] The travel motor is a 24V DC dual-axis worm gear reduction self-locking motor, and the constant output speed is set to 35-50r / min, which can prevent the feeding cart (51) from sliding when it stops, thereby ensuring the feeding position accuracy;

[0119] The wheel (582) is configured as a metal U-shaped wheel, and the ratio of the groove width of the metal U-shaped wheel to the diameter of the track (4) is configured to be 1.1-1.5:1, which can prevent the track from being stuck;

[0120] The counter (583) is configured as a photoelectric rotary encoder, and the counter (583) is attached to the surface of the track (4) via a spring tensioning structure to detect the running speed of the feeding vehicle (51) in real time;

[0121] The PWM speed regulator (584) can control the feeding motor (57) by setting the feeding PWM value, so that the auger in the nutrient feeding pipe (54) or the feed feeding pipe (55) can rotate at a specified speed. Specifically, after the Hall sensor obtains the rotation speed of the feeding motor (57), it can transmit it to the PWM speed regulator (584), and the rotation speed of the feeding motor (57) can be set by the PWM speed regulator (584);

[0122] The PWM speed regulator (584) can also control the travel motor by setting the travel PWM value, so that the travel component (58) drives the feeding vehicle to move at a constant speed along the length direction of the track (4). The specific steps are:

[0123] a. Setting the feeding trolley walking speed through the central control screen (585) so that the feeding trolley (51) walks in a fully loaded state, and the PLC controller measures the walking PWM value at the walking speed as the walking initial setting value and records it in the PLC controller;

[0124] b. After the walking PWM value is initially set, the feeding cart (51) automatically calls the walking PWM value when performing the feeding task, and controls the feeding cart (51) to walk at a specified speed through the walking PWM speed regulator (584);

[0125] c. When the feeding cart (51) encounters a walking obstacle or an operating failure, causing the actual walking speed of the feeding cart (51) to be lower than the set speed by more than 50%, and the duration exceeds 3 seconds, the walking component (58) stops running and issues a warning alarm, thereby preventing the firmware of the feeding cart (51) from being damaged and monitoring the walking speed of the feeding cart (51) through the counter (583);

[0126] In steps ac, since the torque of the walking motor is large and the walking resistance is normally within the rated power range, the walking speed is slightly affected when no substantial obstacles are encountered.

[0127] Poultry feed is a non-sticky small particle material and is fed by a spiral auger. The feed delivery volume is proportional to the number of spiral rotations. When the feed density remains unchanged, the feed volume per unit rotation angle is basically constant, so the feed volume can be accurately controlled by setting the speed.

[0128] A calibration method for a poultry feeding device:

[0129] The calibration assembly (6) includes a basin frame (61) connected to the bracket (2), and a weighing basin (62) mounted on the basin frame (61) for receiving feed or nutrients dropped into the feeding cart (51) during the first calibration;

[0130] The basin frame (61) is stepped and matches the number of layers of the frame (1), and is arranged below the charging area (42). The poultry feeding device is specifically calibrated as follows:

[0131] K1, calibrating the volume of nutrients discharged when the auger in the nutrient delivery pipe (54) rotates in a single circle;

[0132] K2, calibrating the volume of feed discharged when the auger in the feed delivery pipe (55) rotates in a single turn;

[0133] K3, calibrate the feeding motor (57);

[0134] The steps for calibrating the volume of nutrients discharged from the nutrient delivery pipe (54) are as follows:

[0135] K11. Select the nutrient to be used, weigh the nutrient mass per unit volume with a graduated cylinder, calculate the nutrient density ρ1, and input the obtained ρ1 value into the dialog box of the auxiliary material calibration interface of the central control screen (585).

[0146] K21. Select the type of feed to be used, weigh the mass of the feed per unit volume with a measuring cylinder, calculate the feed density ρ2, and input the obtained ρ2 value into the dialog box of the main material calibration interface of the central control screen (585). The specific formula of feed density ρ2 is:

The specific formula is as follows:

[0151] m4=M2 / t2;

[0152] K24. Calculate the feed volume V2 discharged when the auger rotates single circle based on the obtained m4 value, and complete the feed volume V2 calibration. The specific calculation formula is as follows:

[0153] V2=m4 / ρ2;

By knowing the volume of feed or nutrients discharged when the auger rotates in a single circle, the density calculated in advance can be used to obtain the mass of feed or nutrients discharged by volume when the auger rotates in a single circle, that is, the feeding amount.

[0166] The poultry feeding device further comprises a plurality of segmented plates (7) arranged transversely at the bottom of the track (4), a plurality of detection magnets (8) being mounted on the segmented plates (7), and a plurality of Hall proximity switches (9) mounted below the control box (581);

[0167] The number of detection magnets (8) to be installed is set according to the segmentation requirements of the feeding sections of different cage layers of the breeding cage (3). Specifically, the detection magnets (8) are installed at corresponding positions representing the cage layers to be detected to complete the segmentation of the feeding sections of the specific cage layers.

[0168] The feeding method of the poultry feeding device comprises the following steps:

[0169] A1. Number the breeding cages (3) according to the number of layers of the breeding cages (3). The specific numbering steps are as follows:

[0170] A11. Assume that the breeding cage (3) has three layers, and the left channel is L and the right channel is R;

[0171] A12, the layers from the bottom to the top on the left side of the breeding cage (3) are marked as L1, L2, and L3, and the layers from the bottom to the top on the right side of the breeding cage (3) are marked as R1, R2, and R3;

[0172] A2. Install detection magnets (8) in sections at symmetrical positions on both sides of each segment plate (7) at equal distances, and number the detection magnets (8);

[0173] The number of the detection magnet (8) is consistent with the number of the corresponding cage layer below it, that is, the numbers from left to right are L1, L2, L3, R3, R2, R1;

[0174] A3. Input feed amounts for different feeding sections on different layers on the central control screen (585) according to the distribution and feeding requirements of the poultry in the breeding cage (3);

[0175] A4. According to the distribution and feeding requirements of the poultry in the breeding cage (3), the nutrient feeding amount of different feeding sections in different cage layers is input on the central control screen (585). The specific steps are as follows:

[0176] A41. Add the same or different types of nutrients to the auxiliary material bins (53) on both sides of the main material bin (52) according to the poultry feeding requirements, and input the corresponding nutrient density into the nutrient density dialog box on the central control screen (585);

[0177] A42. Enter the nutrient feeding amount required for each poultry in each layer into the corresponding feeding segment dialog box;

[0178] Among them, different types of nutrients can be added twice in the auxiliary material bins (53) on both sides within one day, and no nutrients are added to the auxiliary material bins (53) corresponding to the cage layer that does not require nutrients;

[0179] A5. According to the distribution and feeding requirements of the poultry in the breeding cage (3), each cage layer is segmented, and at different segment positions, the feeding motor (57) is made to feed according to the input nutrient feeding amount or feed feeding amount. The specific steps are as follows (the following two segment plates (7) are used as an example)

[0180] A51. Assume that the number of segmentation plates (7) installed is two, and the two segmentation plates (7) divide the breeding cage (3) into feeding sections along the length direction of the track (4);

[0181] The specific feeding stages are: feeding stage 1, feeding stage 2, and feeding stage 3;

[0182] A52. When the feeding vehicle (51) starts to start, the PLC controller reads the feed feeding amount and nutrient feeding amount pre-entered for the breeding cage (3) at the feeding section, and controls the feeding motor (57) to discharge the corresponding feeding amount for the poultry in the feeding section to eat;

[0183] A53. When the feeding cart (51) reaches the top of the first segment plate (7), the Hall proximity switch (9) detects the detection magnet (8) on the segment plate (7), indicating that the feeding cart (51) has entered the second feeding section. The PLC controller identifies and determines the number of the detection magnet (8), reads the feed feeding amount and nutrient feeding amount previously inputted on the second feeding section, and controls the feeding motor (57) to discharge the corresponding feeding amount for the poultry in the second feeding section to eat.

[0184] A54. When the feeding cart (51) reaches above the second segment plate (7), the Hall proximity switch (9) detects the detection magnet (8) on the segment plate (7), indicating that the feeding cart (51) has entered the third feeding segment. The PLC controller identifies and determines the number of the detection magnet (8), reads the feed feeding amount and nutrient feeding amount previously inputted on the third feeding segment, and controls the feed conveying motor (57) to discharge the corresponding feeding amount for the poultry in the third feeding segment to eat.

[0185] A55, when the feeding car (51) completes feeding, it returns along the track (4) to the charging area (42) for charging, and adding feed and nutrients to prepare for the next feeding;

[0186] In step A3, according to the distribution and feeding requirements of the poultry in the breeding cage (3), the feed feeding amount of different feeding sections in different cage layers is input on the central control screen (585). The specific steps are as follows:

[0187] A31, measure the density of the feed to be fed, and input the density of the feed into the feed density dialog box of the central control screen (585);

[0188] A32. Set the feeding amount for each poultry in each feeding section and input the result into the dialog box of the corresponding feeding section;

[0189] In steps A52-A54, the feeding motor (57) is controlled to discharge the corresponding feeding amount. The specific steps are as follows:

[0190] A541、Assume that the feeding amount of a single poultry is m 单 , the stocking density of each layer of the breeding cage (3) is the same, then the number of poultry raised per meter in the feeding section of this layer is equal, set to n, and the walking speed of the feeding car (51) is V 速 m / min, the feeding speed of the feeding car is M 设 g / min;

[0191] A542, n, V 速 Input the data into the dialog box of the feeding section corresponding to the central control screen (585), and the PLC controller automatically calls the feeding amount m 单 , thus calculating the feeding amount M of this feeding segment 设 , the specific formula is as follows:

[0192] M 设 =V 速 *n*m 单

[0193] Among them, the PLC controller automatically calls the feeding amount m 单 Equal to the input value of the feeding amount for a single poultry in each feeding segment in step A32;

[0194] A543, according to the obtained feeding speed M 设 , calculate the PWM value U required to be set for the feeding motor (57) of the feeding section through the calculation formula of the PWM value U, and complete the setting of the feeding speed;

[0195] A544, repeating steps A541-A543 to complete the setting of the feeding speed of each feeding section on each layer of the breeding cage (3), so that the feeding motor (57) can discharge the corresponding feeding amount;

[0196] Since the traveling speed of the feeding vehicle (51) is constant, the feeding amount of nutrients or feed can be completed by controlling the rotation speed of the feeding motor (57) of each cage layer.

[0197] When the present invention is used, poultry of different numbers and densities are fed in each layer of the breeding cage (3) according to demand, and the corresponding feeding amount for a single poultry is input in the central control screen (585) according to the actual number of poultry in each cage layer per meter. The volume of nutrients discharged by the nutrient delivery pipe (54) is calibrated by utilizing the principle that the volume of nutrients discharged when the auger in the nutrient delivery pipe (54) rotates in a single circle, and the volume of feed discharged by the feed delivery pipe (55) is calibrated to know the volume of feed discharged when the auger in the feed delivery pipe (55) rotates in a single circle. The speed of the delivery motor (57) at the end of the nutrient delivery pipe (54) and the delivery motor (57) at the end of the feed delivery pipe (55) are controlled by calibrating the delivery motor (57), so that each delivery pipe (54) is kept constant. The number of revolutions of the auger driven by the motor (57) is controllable. Thus, when the feeding cart (51) moves on the track (4), it can be fed according to the feeding amount set in advance, and when the Hall proximity switch (9) detects the detection magnet (8) on the segment plate (7), it indicates that it has entered the next feeding section. The PLC controller identifies and determines the number of the detection magnet (8), reads the feed feeding amount and the nutrient feeding amount previously input on the feeding section, and controls the feeding motor (57) to discharge the corresponding feeding amount for the poultry in the feeding section to eat. As a result, when the feeding cart (51) moves on the feeding section, the speed of the output end of the feeding motor (57) automatically changes, thereby enabling the feeding cart (51) to automatically change the feeding amount in different feeding sections, and control the feeding amount according to the number of poultry per meter in the feeding section, so that the feeding amount of feed and nutrients is appropriate.

[0198] Regardless of how the types of feed and nutrients change, that is, how the density changes, only one calibration is required. After the corresponding density is input on the central control screen (585), the calibration method and feeding method of the present application can be used to directly realize the quick calibration and setting of different feeding sections, and the reasonable number of rotations of the feed motor (57) driven by the auger required for different feeding sections on the breeding cage (3) can be given in the first time, so that the feeding cart (51) becomes personalized during feeding, can adapt to different feeds or nutrients, and can be accurately controlled. The feeding accuracy is high, and the nutritional needs of poultry at different positions and times can be met to the greatest extent.

[0199] This embodiment specifically solves the problem that the current multi-layer poultry cage feeding equipment in the prior art cannot reasonably provide the feeding amount of feed and nutrients according to the actual needs of poultry in different cages during actual use, resulting in the inability to quantify the feeding amount and poor feeding accuracy, which needs to be improved.

[0200] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
