Description

Technical Field

[0001] The present invention relates to the technical field of livestock breeding equipment, and particularly relates to an intelligent feeding system for a sunlight pigsty and a using method thereof. Background Art

[0002] The sunlight pigsty breeding mode is a pigsty with a basic frame structure of steel bars, cement, sunlight panels or plastic films and cold-proof quilts using solar radiation as the light source and heat source. It can make full use of the advantages of sunlight. The direct sunlight and ultraviolet rays can effectively kill viruses and bacteria, reduce the load of harmful bacteria and viruses in the environment, and improve the air quality and temperature of the pigsty by comprehensively adjusting ventilation.

[0003] The sunlight pigsty has broad application prospects, but most of the existing sunlight pigsties still adopt traditional feeding methods. However, there are multiple technical bottlenecks in the existing traditional feeding methods:

[0004] 1. Manual feeding has an efficiency ceiling. The daily feeding amount of a single labor force does not exceed 300 pigs, and intelligent improvement is urgently needed. The authorized announcement number CN108371111B discloses an automatic pig feed feeder. Although this invention solves the problem that the feeding trough is easily contaminated when not in use; however, when the feeding trough is not feeding, it is set inside the machine body. If the volume of the feeding trough is increased, the machine body will inevitably increase accordingly. To ensure the overall coordination of the equipment, obviously the volume of the feeding trough cannot be too large. Therefore, this device cannot meet the simultaneous feeding of multiple pigs.

[0005] 2. The open feeding trough causes the feed exposure time to exceed 2 hours, resulting in the colony exceeding the standard, which is likely to affect the normal development of pigs after eating; in addition, for the sunlight pigsty, due to the ground window, the feed in the feeding trough is easily affected by the wind and is particularly prone to drying; in some traditional sunlight pigsties, part of the bottom of the plastic film is often rolled up for ventilation and cooling. When the wind speed is high, it is very easy to make the feeding material too dry and bring in some dust and sand. On the one hand, it seriously affects the palatability of the feeding material, and on the other hand, it is also easy to cause oxidation of some nutrients and reduce the nutritional value.

[0006] 3. The high nutritional loss rate caused by the uneven mixing of solid-liquid feed, and at the same time, the existing mixing device is extremely easy to cause feed fragmentation during feeding, stirring, and conveying, resulting in the loss of nutrients and feed waste. It is very difficult to achieve a balance between the mixing uniformity and the fragmentation rate.

[0007] Therefore, it is necessary to develop a new type of intelligent feeding system for sunlight pigsties. Summary of the Invention

[0008] The main object of the present invention is to provide an intelligent feeding system and a usage method for a sunlight pigsty. Through the cooperation of components such as a mixing chamber, a stirring mechanism, a feeding trough, and sensors, the intelligent feeding system of the present invention can not only significantly improve the mixing uniformity of feed, reduce the physical damage to the feed during the mixing and conveying processes, lower the feed breakage rate, and solve the problem of difficult balance between feed mixing uniformity and physical damage; at the same time, it can also ensure the freshness and nutritional value of the feed in the feeding trough, effectively reduce feed waste and reduce the influence of wind on the feed. The intelligent feeding system of the present invention is particularly suitable for sunlight pigsties.

[0009] To achieve the above object, the present invention adopts the following technical solutions:

[0010] In the first aspect of the present invention, there is provided an intelligent feeding system for a sunlight pigsty, the system comprising a horizontally arranged mixing chamber, a storage component arranged directly above one end of the mixing chamber, a feeding trough arranged at the other end of the mixing chamber, a stirring mechanism arranged in the mixing chamber, a frame for fixing the storage component and the mixing chamber, as well as an opening and closing component, a gravity sensor, a humidity sensor, a wind sensor, and a controller.

[0011] One end of the mixing chamber is fully enclosed, and the other end is provided with a discharge port; the upper half of the mixing chamber is an anti-residual cavity, and the lower half is a material conveying cavity; the cross-section of the anti-residual cavity is semi-circular and the cross-sectional radius decreases horizontally from the fully enclosed end of the mixing chamber to the discharge port end; the cross-section of the material conveying cavity is a rounded rectangle, the bottom is set as a slope surface, and the top of the slope is located on the side of the storage component, and the bottom of the slope is located on the side of the feeding trough; gravity sensors and humidity sensors are arranged at the bottom of the material conveying cavity and the bottom of the feeding trough, and a wind sensor is arranged at the top of one end of the feeding trough.

[0012] The stirring mechanism is arranged in the mixing chamber, and a driving component for driving the stirring mechanism is arranged on the side of the mixing chamber away from the feeding trough; the stirring mechanism includes a stirring shaft and stirring blades, and the distance from the top of the stirring blades to the stirring shaft decreases sequentially from the end close to the driving component to the end close to the discharge port.

[0013] The cross-section of the residue-proof cavity of the mixing chamber in the present invention is semi-circular, and the cross-sectional radius decreases horizontally from the fully enclosed end of the mixing chamber to the discharge port end. The curved surface design can reduce turbulence and local resistance, making the material flow more smoothly, reducing material adhesion, and preventing feed from remaining on the cavity. Additionally, the cavity structure in the present invention can generate shear force during the flow of the feed, effectively breaking up agglomerates, especially suitable for feed components with high fiber content or easy to agglomerate, and can promote the redistribution of feeds with different densities or particle sizes, reducing the layering phenomenon, and improving the mixing efficiency and mixing uniformity of the feed. The residue-proof cavity of the cavity can form a funnel effect during discharging, accelerating the discharge of materials and reducing the risk of blockage, especially having a significant effect on high-humidity or viscous feeds. The bottom of the feeding cavity is set as a slope, which is more conducive to the flow of the feed to the discharge port after uniform mixing.

[0014] The distance from the top of the stirring blade of the stirring mechanism to the stirring shaft decreases successively from the end close to the driving component to the end close to the discharge port. This can promote the stratified mixing of materials with different densities or particle sizes, reducing the layering phenomenon. The longer blades provide gentle stirring to avoid excessive impact on fragile particles (such as expanded feed, vitamin premix); the shorter blades shear and process agglomerates through high speed, reducing physical damage to the feed while promoting uniform mixing of the feed.

[0015] The setting of the gravity sensor is conducive to the precise control of the feed quantity in the mixing chamber and the feeding trough. The humidity sensor can monitor the mixing uniformity of the feed, and the wind sensor can detect the wind speed in the pigsty in real time. According to the change of the wind sensor value, the controller can timely adjust relevant components to reduce the impact of ventilation on the freshness of the feed in the feeding trough and the mixing chamber.

[0016] Preferably, a plurality of stirring blades are evenly arranged around the stirring shaft for one week and taken as a group, and several groups are arranged on the stirring shaft; taking the midpoint of the stirring shaft as the boundary, the end close to the storage component is the front end, and the end close to the discharge port is the rear end. The group spacing between adjacent two groups of stirring blades at the front end of the stirring shaft is less than that at the rear end. Preferably, the group spacing between adjacent two groups of stirring blades at the front end is 30 - 50 mm; the group spacing between adjacent two groups of stirring blades at the rear end is 80 - 100 mm. Preferably, the stirring blade is a straight panel.

[0017] Preferably, a plurality of stirring blades are evenly arranged around the stirring shaft for one week and taken as a group, and several groups are arranged on the stirring shaft. The group spacing between adjacent two groups of stirring blades is equal. Preferably, the stirring blade is a curved panel.

[0018] Preferably, the stirring blade is a spiral involute surface, and a plurality of evenly distributed residue-proof scraping blades are arranged on the stirring blade.

[0019] Compared with the conventional spiral stirring mechanism, the above three stirring mechanisms of the present invention can effectively improve the mixing uniformity of the feed, achieve efficient conveying, and reduce the feed breakage rate.

[0020] Preferably, the drive assembly includes a servo motor, a driving gear disposed on the output shaft of the servo motor, and a driven gear coaxially disposed and fixedly connected to the stirring shaft. The driving gear meshes with the driven gear, and the diameter of the driving gear is smaller than that of the driven gear. This structure can achieve the effect of regulating the rotation speed and enable the stirring mechanism to perform low-shear stirring.

[0021] Preferably, the storage assembly includes a storage bin and a feeding port, and the feeding port communicates with the mixing chamber; a feeding valve plate and a vibrating plate are sequentially arranged from top to bottom at the feeding port. The feeding valve plate is connected with a first opening and closing assembly, and the vibrating plate is connected with a vibrating motor; the first opening and closing assembly is fixedly connected to the anti-residue cavity.

[0022] Preferably, a discharge baffle is arranged at the discharge port of the mixing chamber, and the discharge baffle is connected with a second opening and closing assembly; a feeding port is opened on the feeding trough, and the feeding port communicates with the discharge port of the mixing chamber; two groups of the second opening and closing assemblies are symmetrically arranged, and both ends of each group of the second opening and closing assemblies are hinged to the anti-residue cavity and the discharge baffle respectively.

[0023] Preferably, the first opening and closing assembly, the second opening and closing assembly, the drive assembly, the vibrating motor, the gravity sensor, the humidity sensor, and the wind sensor are all connected to the controller.

[0024] In the intelligent feeding system of the present invention, the opening and closing assembly is controlled by the controller to form a closed space in the mixing chamber. The closed space can not only prevent the dust generated during the feed stirring process from escaping into the pigsty, but also prevent the influence on the freshness of the mixed feed in the mixing chamber when the wind speed in the pigsty is too high.

[0025] In the system of the present invention, the vibrating plate and the vibrating spring are arranged at the feeding port, far away from the storage bin. The feed is only affected by vibration when passing through the feeding port during the falling process, reducing the feed breakage rate.

[0026] Preferably, both ends of the stirring shaft are seamlessly butted with the mixing chamber through flange bearings, and a silica gel layer is coated on the stirring blades. The setting of the silica gel layer can effectively prevent physical damage to the feed caused by stirring.

[0027] Preferably, the lateral reduction angle of the anti-residue cavity is 10° - 30°. Within this angle range, it is helpful to improve the feed mixing efficiency and mixing uniformity.

[0028] Preferably, the adjustment range of the discharge baffle is 0° - 60°. This adjustment range can meet the discharge requirements and avoid the influence of wind on the feed in the mixing chamber.

[0029] Preferably, the slope angle of the bottom slope of the material feeding cavity is ≥15°.

[0030] Preferably, a material distributing slope is arranged at the bottom of the feeding trough. The cross section of the material distributing slope is an isosceles triangle, and the highest point of the isosceles triangle is directly below the feeding port. The mixed feed can be quickly distributed to both sides of the feeding trough, which can meet the common feeding of multiple pigs.

[0031] Preferably, a high-density polyethylene coating is arranged on the surface of the material distributing slope.

[0032] The present invention also provides a using method of the intelligent feeding system for the above-mentioned sunlight pigsty, and the method comprises the following steps:

[0033] During feeding, the controller controls the first opening and closing component and the second opening and closing component to make the blanking valve plate and the discharge baffle in a completely closed state. After all the solid feed enters the storage bin, the blanking valve plate is gradually opened; meanwhile, the vibration motor is started to make the spring vibrating piece in a continuous vibration state until all the solid feed enters the mixing cavity;

[0034] After all the solid feed enters the mixing cavity, a low-viscosity liquid additive is added through the storage bin. After the addition is completed, the blanking valve plate is closed, and the stirring mechanism is started to stir and mix at 15-30 r / min;

[0035] When the humidity sensor reaches the preset value, the rotation speed of the stirring mechanism is adjusted to 5-10 r / min, the discharge baffle is opened, and the uniformly mixed feed flows into the feeding trough; when the remaining amount in the feeding trough reaches the preset value, the controller controls the second opening and closing component to close the discharge baffle; when the remaining amount in the feeding trough remains unchanged for more than 1 hour, manual intervention is carried out to clean the remaining material in the feeding trough to avoid oxidation of the remaining material; when the remaining amount in the feeding trough is less than the preset value, the controller controls the second opening and closing component to open the discharge baffle to make the feed in the mixing cavity enter the feeding trough;

[0036] The addition amount and addition frequency of the feed in the feeding trough are determined according to the wind speed. If the wind speed > 3 m / s, the opening degree of the discharge baffle is reduced, the addition amount of the single-time feed is reduced, and the addition frequency is increased.

[0037] Preferably, when the remaining amount of the material in the mixing cavity < 20%, the stirring mechanism is switched to the intermittent stirring mode. This can prevent idling wear and save energy.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] Through the design of components such as the mixing chamber and the stirring mechanism described in the present invention, the mixing uniformity of the feed can be significantly improved, and the impact of mixing, stirring, and conveying on the feed breakage rate can be reduced, solving the problem that it is difficult to balance the mixing uniformity and physical damage of the feed. At the same time, through the cooperation of various components, the intelligent feeding system described in the present invention can effectively maintain the freshness of the feed in the feeding trough and the mixing chamber, prevent the loss of nutrients, and ensure the nutritional value of the feed. The structures of the mixing chamber and the feeding trough described in the present invention are not prone to feed residue, effectively avoiding waste and deterioration pollution caused by feed residue. Based on the above discussion, the intelligent feeding system described in the present invention can effectively reduce feed waste and ensure the nutritional value of the feed.

[0040] During the operation process, the intelligent feeding system described in the present invention can simultaneously satisfy the feeding of multiple pigs, without excessive manpower, and can effectively prevent the influence of wind on the feed, especially suitable for solar pig houses.

[0073] The usage method of the intelligent feeding system for the sunlight pigsty includes the following steps:

[0074] When feeding, the controller controls the first opening and closing assembly 104 and the second opening and closing assembly 304 to make the blanking valve plate 103 and the discharge baffle 303 in a completely closed state. After all the solid feed enters the storage bin 101, the blanking valve plate 103 is gradually opened; at the same time, the vibration motor 106 is started to make the vibration piece 105 in a continuous vibration state until all the solid feed enters the mixing chamber 3.

[0075] After all the solid feed has entered the mixing chamber 3, add a low-viscosity liquid additive through the storage bin 101. After the addition is completed, close the feeding valve plate 103 and start the stirring mechanism 6 to stir and mix at 20 r / min.

[0076] When the humidity sensor in the mixing chamber 3 reaches the preset value, adjust the rotation speed of the stirring mechanism 6 to 8 r / min, open the discharge baffle 303, and the uniformly mixed feed flows into the feeding trough 4.

[0077] When the remaining amount in the feeding trough 4 reaches the preset value, the controller controls the second opening and closing component 304 to close the discharge baffle 303; when the remaining amount in the feeding trough 4 remains unchanged for more than 1 hour, perform manual intervention to clean the remaining material in the feeding trough 4 to avoid oxidation of the remaining material; when the remaining amount in the feeding trough 4 is less than the preset value, the controller controls the second opening and closing component 304 to open the discharge baffle so that the feed in the mixing chamber 3 enters the feeding trough 4.

[0078] Determine the addition amount and addition frequency of the feed in the feeding trough 4 according to the wind speed. If the wind speed > 3 m / s, reduce the opening degree of the discharge baffle 303, reduce the single addition amount of the feed, and increase the addition frequency.

[0079] When the remaining material amount in the mixing chamber 3 < 20%, switch the stirring mechanism 6 to the intermittent stirring mode (running for 10 s / pausing for 30 s), which can prevent idling wear and save energy.

[0080] After testing, the feed breakage rate after mixing is 0.85%, the feed mixing uniformity is 98.7%, the CV value is 2.12%, and the humidity fluctuation of the feed in the mixing chamber and the feeding trough after mixing is < ±2%.

[0081] Example 2:

[0082] An intelligent feeding system for a sunlight pigsty, the difference between this system and that of Example 1 lies in the different stirring mechanism 6, and the others are the same as those of Example 1.

[0083] As Figure 9 shown, for the stirring mechanism 6 in this embodiment, taking the midpoint of the stirring shaft 601 as the boundary, the end close to the storage component 1 is the front end, and the end close to the feeding trough 4 is the rear end.

The front-end distance of 50 mm is for rapid feeding, and the rear-end distance of 80 mm enhances the mixing uniformity. The stirring blade 602 is a straight panel.

[0084] The feed crushing rate of the intelligent feeding system for the sunlight pigsty is 0.78%, the feed mixing uniformity is 99.2%, the CV value is 2.35%, and the humidity fluctuation of the feed in the mixing chamber and the feeding trough after mixing is <±2%.

[0085] Example 3:

[0086] An intelligent feeding system for a sunlight pigsty, the difference between this system and that of Example 1 lies in the stirring mechanism 6, and the others are the same as those of Example 1.

[0087] As Figure 10 、 Figure 11 As shown, in the stirring mechanism 6 of this embodiment, the stirring blade 602 is a spiral involute surface, and a number of uniformly distributed anti-residue scraping blades 603 are arranged on the stirring blade 602. Designing the stirring blade 602 as a spiral involute surface can more efficiently realize the mixing and conveying of the mixed feed, and at the same time can reduce the physical damage to the feed during the working process and reduce the feed crushing rate. The anti-residue scraping blades 603 can not only better mix the feed, but also effectively avoid the residue of the mixed feed on the anti-residue cavity 301.

[0088] The feed crushing rate of the intelligent feeding system for the sunlight pigsty is 0.71%, the feed mixing uniformity is 90.6%, the CV value is 2.06%, and the humidity fluctuation of the feed in the mixing chamber and the feeding trough after mixing is <±2%.

[0089] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and shall be included in the protection scope of the present invention.
