Description

Technical Field

[0002] Livestock breeding is a production activity that involves artificially raising, breeding, and managing livestock and poultry such as pigs, chickens, ducks, etc. to obtain livestock products such as meat, eggs, milk, wool, and leather. During the growth process of pigs, when there are sharp changes in environmental temperature, epidemics of acute infectious diseases, stress responses, etc., it will first be manifested in the decrease in the feed intake of pigs. Most traditional pig farms use stainless steel feed troughs, and it is impossible to count the specific value of how much feed a pig eats every day. Therefore, the breeder cannot obtain the abnormal information of the pigs in the first time; With the vigorous development of the intelligence of pig farms, intelligent feeding equipment has been comprehensively developed and popularized. During the intelligent feeding process of pigs, the feed is prone to moisture absorption and caking during long-term storage, which affects the discharging work of the feed. To improve the feeding effect, usually dry feed and water are mixed before feeding to promote nutrient absorption and improve the feeding efficiency. However, a large amount of the mixture of feed and water must be stored in the silo of the intelligent feeding equipment. Affected by the environment and time, the mixed feed is prone to deterioration, and there will be residual feed residues and dirt in the feed tray, which is easy to breed bacteria. During the next intelligent feeding, the feed residues and dirt will be mixed with the feed, which will affect the health and survival rate of pigs. Summary of the Invention

The first bevel gear is located inside the shielding cover.

[0007] As a further solution of the present invention, the premixing component includes a premixing cylinder. The premixing cylinder is fixed on the baffle. A rotating shaft is rotatably connected inside the premixing cylinder. A plurality of stirring rods are fixed outside the rotating shaft. A solenoid valve is installed at the bottom of the premixing cylinder. And an observation window is provided on the outside of the premixing cylinder.

[0010] As a further solution of the present invention, the flushing assembly includes a tee pipe, the top end of the tee pipe is communicated with the bottom end of the hollow shaft, two spray pipes are arranged below the tee pipe, the two spray pipes are respectively fixedly connected to both sides of the scraping strip, both the scraping strip and the spray pipes are of U-shaped design, and a plurality of nozzles are installed on the outer wall of the spray pipes. Three connecting pipes are communicated between the two spray pipes, and the three ports of the tee pipe are respectively communicated with branch pipes, and the ends of the branch pipes are communicated with the connecting pipes.

[0011] As a further solution of the present invention, a control panel is installed on the front surface of the baffle, and visual detection mechanisms are respectively installed on both sides of the bottom of the box body. The visual detection mechanism includes an image acquisition and region division module, a livestock detection module and a feed detection module. The image acquisition and region division module divides the region inside the feed tray collected by the camera to obtain a plurality of feed detection regions. The livestock detection module performs edge detection on each feed detection region to judge whether there is livestock eating. If there is livestock, the detection result of this region is not effectively recorded. For the regions without livestock, the feed detection module performs detection based on the RGB color components. By analyzing the colors of the pixel points, the feed and the background color of the feed tray are distinguished, so as to obtain the position and area ratio of the feed, and then estimate the remaining amount of the feed. The output end of the visual detection mechanism is connected to the input end of the control panel, and the control panel is used for automatically giving an alarm according to the information fed back by the visual detection mechanism.

[0012] A using method of an automatic warning feeding device for livestock, the using method includes the following steps: When feeding livestock, open the cover plate to add dry feed into the silo, and then close the cover plate. When the visual detection mechanism works, the image acquisition and region division module divides the region inside the feed tray collected by the camera to obtain multiple feed detection regions. The livestock detection module performs edge detection on each feed detection region to determine whether there are livestock eating. If there are livestock, the detection result of this region is not recorded effectively. For the regions without livestock, the feed detection module performs detection based on the RGB color components. By analyzing the colors of the pixel points, it distinguishes the feed from the bottom color of the tray, thereby obtaining the position and area ratio of the feed, and further estimating the remaining amount of the feed. If the livestock is within the detection range and no feed is detected in the tray, the visual detection mechanism transmits a signal to the control panel, and the control panel remotely controls the first motor to work. The first motor drives the spiral blade to rotate through the fixed shaft. When the feed in the silo enters the barrel, it rotates in cooperation with the spiral blade, enabling the spiral blade to convey the feed towards the direction of the premixing component. During the process of conveying the feed, the spiral blade crushes the agglomerated feed, and the feed is introduced into the premixing cylinder through the discharge pipe; At this time, the first water pump works, enabling the first water pump to inject water into the interior of the premixing cylinder through the water suction pipe and contact with the feed. During the rotation of the fixed shaft, it drives the first bevel gear to rotate. The first bevel gear drives the rotating shaft to rotate through the second bevel gear, and the rotating shaft drives multiple external stirring rods to rotate, enabling the stirring rods to mix and stir the dry feed and water to obtain the mixed feed. When the stirring work is completed, the control panel transmits a signal and opens the solenoid valve, enabling the mixed feed inside the premixing cylinder to be discharged through the solenoid valve and fall into the tray. When the visual detection mechanism estimates that the remaining amount of the feed is within the specified range, the solenoid valve closes, preventing the mixed feed inside the premixing cylinder from falling into the tray. By premixing the dry feed and water and then feeding, the freshness of the feed is ensured; When the livestock detection module performs edge detection on each feed detection region to determine whether there are livestock eating, if there are no livestock eating and after a single feeding operation is completed, the control panel transmits a start signal to the two electro-hydraulic rods. The two electro-hydraulic rods extend and drive the box body to move downward. The box body then moves downward through the liquid guide component and the flushing component. When the flushing component contacts the inner wall of the tray, the two discharge valves at the bottom of the tray are in the open state. Connect the water guide pipe to the water source. The second motor and the second water pump work simultaneously. The output shaft of the second motor drives the driving gear to rotate. The driving gear drives the hollow shaft to rotate through the driven gear. The hollow shaft is supported by the bearing seat at the bottom of the box body to improve the rotational stability of the hollow shaft. The hollow shaft drives the scraper to rotate through the cross bar and two reinforcing rods, enabling the scraper to scrape the inner wall of the tray. The second water pump works to pump water through the water guide pipe, and the water is introduced into the hollow shaft through the rotary joint. When the hollow shaft rotates, the rotary joint at the top ensures the normal conduction of the water outlet end of the second water pump and the hollow shaft; Water is introduced into the three-way pipe in the flushing assembly through a hollow shaft. The three-way pipe introduces water into the connecting pipe through three branch pipes. Since the two nozzles are connected through the three connecting pipes, water will enter the nozzle and be sprayed out from multiple nozzles. The nozzles will increase the water pressure of the water outlet. The scraper bar and the nozzle are both U-shaped. The two nozzles are respectively located on both sides of the scraper bar, so that the scraper bar is in full contact with the inner wall of the material tray in all directions. Several nozzles are respectively facing the inside of the material tray. In the process of the scraper bar driven by the cross bar to rotate, the scraper bar will scrape off the residue attached to the inner wall of the material tray. The two nozzles are respectively located on both sides of the scraper bar, and cooperate with the high-pressure water to impact the inner wall of the material tray, so that the scraping and impact range covers the inner wall of the material tray, thereby improving the cleaning effect of the material tray. The sewage and residues generated by cleaning are discharged through the two discharge valves at the bottom of the material tray, thereby achieving the purpose of automatic cleaning of the material tray. After the cleaning work is completed, the second motor and the second water pump stop working, the two electric hydraulic rods shrink and drive the box body to move upward, and the box body drives the scraper and the nozzle to move upward and leave the feed tray through the hollow shaft and the cross bar. After the sewage and residue inside the feed tray are discharged, the discharge valve is closed, and the visual detection mechanism performs edge detection on each feed detection area to determine whether there are livestock eating. If there are livestock, and the feed detection module detects that there is no feed inside the feed tray, the visual detection mechanism transmits the signal to the control panel, and the control panel sends a start signal to control the motor 1 to work, so that it can perform the next automatic feeding work. The visual detection mechanism detects the amount of food consumed by the livestock every day, and after counting the specific values, the data is transmitted to the remote terminal. When the feed intake suddenly changes abnormally, the abnormality is analyzed and pushed through the background terminal, so that the breeder can get the early warning information in the first time, which is convenient for quickly judging the health status of the livestock, thereby reducing losses; When replacing the material tray, loosen the screws on the fixing seat to separate the screws from the base. At this time, the fixing seat and the base are in an active state. Lift the fixing seat to separate it from the base, and then remove the material tray from the base. When installing the material tray, clamp the material tray inside the fixing seat, and the blocks on both sides of the bottom of the fixing seat are inserted into the grooves on the base to limit the fixing seat and the base. Use the screws to fix the fixing seat to the base, thereby improving the stability of the installed material tray.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by controlling the simultaneous operation of the second motor and the second water pump, the output shaft of the second motor drives the driving gear to rotate. The driving gear drives the hollow shaft to rotate through the driven gear, and the hollow shaft is supported by the bearing seat at the bottom of the box body to improve the rotational stability of the hollow shaft. The hollow shaft drives the scraping bar to rotate through the cross bar and two reinforcing bars, so that the scraping bar scrapes the inner wall of the feeding tray. The second water pump works to pump water through the water guide pipe, and the water is introduced into the hollow shaft through the rotary joint. When the hollow shaft is rotating, the rotary joint at the top ensures the normal conduction between the water outlet end of the second water pump and the hollow shaft. The water is introduced into the hollow shaft through the rotary joint and then into the three-way pipe in the flushing assembly through the hollow shaft. The three-way pipe introduces the water into the connecting pipe through the three branch pipes. Since the two spray pipes are connected through the three connecting pipes, the water will enter the spray pipes and be ejected from multiple nozzles. The nozzles will increase the water pressure of the water outlet, and both the scraping bar and the spray pipes are U-shaped. The two spray pipes are respectively located on both sides of the scraping bar, so that the scraping bar is in full contact with the inner wall of the feeding tray. Several nozzles are respectively oriented towards the inside of the feeding tray. During the process of the cross bar driving the scraping bar to rotate, the scraping bar will scrape off the residues attached to the inner wall of the feeding tray, and the two spray pipes are respectively located on both sides of the scraping bar, cooperating with the high-pressure water to impact the inner wall of the feeding tray, so that the scraping and impact range covers the inner wall of the feeding tray, improving the cleaning effect of the feeding tray. The sewage and residues generated by the cleaning are discharged through the two discharge valves at the bottom of the feeding tray, thus achieving the purpose of automatically cleaning the feeding tray, preventing the long-term attachment of residual feed residues and dirt in the feeding tray, reducing the breeding of bacteria in the feeding tray, and being beneficial to improving the health and survival rate of livestock during the feeding process; 2. In the present invention, the fixed shaft drives the spiral blade to rotate. When the feed in the feed bin enters the feed cylinder, it rotates in cooperation with the spiral blade, so that the spiral blade can convey the feed in the direction of the premixing assembly. During the process of conveying the feed, the spiral blade crushes the agglomerated feed, and the feed is introduced into the premixing cylinder through the discharge pipe. The first water pump injects water into the interior of the premixing cylinder through the water suction pipe and contacts the feed. During the rotation of the fixed shaft, it drives the first bevel gear to rotate. The first bevel gear drives the rotating shaft to rotate through the second bevel gear, and the rotating shaft drives the multiple stirring rods outside to rotate, so that the stirring rods mix and stir the feed dry matter and water to obtain the mixed feed. When the stirring work is completed, the control panel transmits a signal and opens the solenoid valve, so that the mixed feed in the premixing cylinder is discharged through the solenoid valve and falls into the feeding tray. When the visual detection mechanism estimates that the remaining amount of the feed is within the specified range, the solenoid valve closes, so that the mixed feed in the premixing cylinder no longer falls into the feeding tray. By premixing the feed dry matter and water and then feeding, the freshness of the feed is guaranteed, and the traditional feeding method of adding the mixed feed into the feed bin together is abandoned, preventing the mixture of the dry matter and water from deteriorating due to the influence of the environment and time, thus ensuring the freshness of the feed. The fresh feed can also increase the appetite and digestion and absorption ability of livestock and promote their growth and development. Description of the Drawings

Discharge valves 402 are respectively installed on the front and rear sides of the bottom of the tray 401. The sewage and residues generated during cleaning are discharged through the two discharge valves 402 at the bottom of the tray 401 to prevent dirt from remaining inside the tray 401. A fixed seat 403 is provided between the two discharge valves 402. The inner wall of the fixed seat 403 is clamped with the bottom of the tray 401.

Since the two spray pipes 164 are conducted through the three connecting pipes 163, water will enter the spray pipes 164 and be sprayed out from multiple nozzles 165. The nozzles 165 will increase the water pressure of the water outlet, thereby improving the flushing effect on the inner wall of the material tray 401.

[0028] The scraping strip 15 is in full contact with the inner wall of the material tray 401. Several nozzles 165 are respectively oriented towards the inside of the material tray 401. During the process of the cross bar 142 driving the scraping strip 15 to rotate, the scraping strip 15 will scrape off the residues attached to the inner wall of the material tray 401, and the two spray pipes 164 are respectively located on both sides of the scraping strip 15, cooperating with the high-pressure water to impact the inner wall of the material tray 401, so that the scraping and impact range covers the inner wall of the material tray 401, improving the cleaning effect on the material tray 401.

[0029] As a further solution of the present invention, a control panel 18 is installed on the front surface of the baffle 6, and visual detection mechanisms 17 are respectively installed on both sides of the bottom of the box body 11. The visual detection mechanism 17 includes an image acquisition and region division module, a livestock detection module and a feed detection module; The image acquisition and region division module divides the region inside the material tray 401 collected by the camera to obtain multiple feed detection regions; The livestock detection module performs edge detection on each feed detection region to judge whether there is livestock eating. If there is livestock, the detection result of this region is not recorded effectively; For the regions without livestock, the feed detection module performs detection based on the RGB color components. By analyzing the colors of the pixel points, the feed and the background color of the material tray 401 are distinguished, so as to obtain the position and area ratio of the feed, and further estimate the remaining amount of the feed; The output end of the visual detection mechanism 17 is connected to the input end of the control panel 18. The control panel 18 is used to automatically issue an early warning based on the information fed back by the visual detection mechanism 17. The visual detection mechanism 17 detects the daily food intake of the livestock, and transmits the data to the remote terminal after counting the specific values. When the feed intake suddenly changes abnormally, the background terminal analyzes the abnormality and pushes it, so that the breeder can get the early warning information in the first time, which is convenient for quickly judging the health status of the livestock, thereby reducing losses.

[0030] A method for using an automatic early warning feeding device for animal husbandry, the method comprising the following steps: When feeding livestock, the cover 19 is opened to add dry feed into the silo 1, and then the cover 19 is closed. When the visual detection mechanism 17 is working, the image acquisition and area division module uses the camera to collect the area in the feed tray 401 and divide it to obtain multiple feed detection areas. The livestock detection module performs edge detection on each feed detection area to determine whether there are livestock eating. If there are livestock, the detection result of the area is not effectively recorded. For areas without livestock, the feed detection module performs detection based on RGB color components, and distinguishes between the feed and the background color of the feed tray 401 by analyzing the color of the pixel points, thereby obtaining the position and area ratio of the feed. The remaining amount of feed is estimated by the weight. If the livestock is within the detection range and no feed is detected in the feed tray 401, the visual detection mechanism 17 transmits a signal to the control panel 18. The control panel 18 remotely controls the motor 1 702 to work. The motor 1 702 drives the spiral blade 704 to rotate through the fixed shaft 703. When the feed in the silo 1 enters the barrel 701, the spiral blade 704 rotates to enable the spiral blade 704 to transport the feed to the direction of the premixing component 9. The spiral blade 704 crushes the agglomerated feed in the process of transporting the feed, so that the feed is introduced into the premixing barrel 901 through the discharge pipe 706. At this time, the first water pump 906 works, so that the first water pump 906 injects water into the premixing barrel 901 through the pumping pipe 907 and contacts the feed. The fixed shaft 703 drives the bevel gear 1 705 to rotate during the rotation process. The bevel gear 1 705 drives the rotating shaft 902 to rotate through the bevel gear 2 908. The rotating shaft 902 drives the external multiple stirring rods 903 to rotate, so that the stirring rods 903 mix and stir the dry feed and water to obtain mixed feed. When the stirring work is completed, the control panel 18 transmits a signal and opens the solenoid valve 904, so that the mixed feed inside the premixing barrel 901 is discharged through the solenoid valve 904 and falls into the feed tray 401. When the visual detection mechanism 17 estimates that the remaining amount of feed is within the specified range, the solenoid valve 904 is closed, so that the mixed feed inside the premixing barrel 901 no longer falls into the feed tray 401. By premixing the dry feed and water, feeding is performed, thereby ensuring the freshness of the feed; In the livestock detection module, edge detection is performed on each feed detection area to determine whether there are livestock eating. If there are no livestock eating and after a single feeding operation is completed, the control panel 18 transmits a start signal to the two electro-hydraulic rods 12. The two electro-hydraulic rods 12 extend and drive the box body 11 to move downward. The box body 11 then moves downward through the liquid guiding assembly 14 and the flushing assembly 16. When the flushing assembly 16 contacts the inner wall of the feed tray 401, the two discharge valves 402 at the bottom of the feed tray 401 are in the open state. The water pipe 147 is connected to the water source. The second motor 131 and the second water pump 146 work simultaneously. The output shaft of the second motor 131 drives the driving gear 132 to rotate. The driving gear 132 drives the hollow shaft 141 to rotate through the driven gear 133. The hollow shaft 141 is supported by the bearing seat 144 at the bottom of the box body 11 to improve the rotational stability of the hollow shaft 141. The hollow shaft 141 drives the scraping strip 15 to rotate through the cross bar 142 and the two reinforcing rods 143, so that the scraping strip 15 scrapes the inner wall of the feed tray 401. The second water pump 146 pumps water through the water pipe 147. The water is introduced into the hollow shaft 141 through the rotary joint 145. When the hollow shaft 141 rotates, the rotary joint 145 at the top ensures the normal conduction of the water outlet end of the second water pump 146 and the hollow shaft 141; The water is introduced into the tee pipe 161 in the flushing assembly 16 through the hollow shaft 141. The tee pipe 161 introduces the water into the connecting pipe 163 through the three branch pipes 162. Since the two spray pipes 164 are connected through the three connecting pipes 163, the water will enter the spray pipes 164 and be sprayed out from the multiple nozzles 165. The nozzles 165 will increase the water pressure of the water outlet. Both the scraping strip 15 and the spray pipes 164 are U-shaped designs. The two spray pipes 164 are respectively located on both sides of the scraping strip 15, so that the scraping strip 15 is in full contact with the inner wall of the feed tray 401 in all directions. The several nozzles 165 are respectively oriented towards the inside of the feed tray 401. During the process of the cross bar 142 driving the scraping strip 15 to rotate, the scraping strip 15 will scrape off the residues attached to the inner wall of the feed tray 401. The two spray pipes 164 are respectively located on both sides of the scraping strip 15, cooperating with the high-pressure water to impact the inner wall of the feed tray 401, so that the scraping and impact range covers the inner wall of the feed tray 401, improving the cleaning effect of the feed tray 401. The sewage and residues generated by the cleaning are discharged through the two discharge valves 402 at the bottom of the feed tray 401, thereby achieving the purpose of automatically cleaning the feed tray 401; After the cleaning work is completed, the second motor 131 and the second water pump 146 stop working. The two electro-hydraulic rods 12 contract and drive the box body 11 to move upward. The box body 11 drives the scraping strip 15 and the spray pipe 164 to move upward through the hollow shaft 141 and the cross bar 142 and separate from the feed tray 401. After the sewage and residue inside the feed tray 401 are discharged, the discharge valve 402 closes. The visual detection mechanism 17 performs edge detection on each feed detection area to determine whether there are livestock eating. If there are livestock and the feed detection module detects that there is no feed inside the feed tray 401, the visual detection mechanism 17 transmits a signal to the control panel 18. The control panel 18 issues a start signal to control the first motor 702 to work, so as to perform the next automatic feeding work. The visual detection mechanism 17 detects the amount of feed eaten by livestock every day, and after counting the specific value, transmits the data to the remote terminal. When the feed intake suddenly changes abnormally, the background terminal analyzes the abnormality and pushes it, so that the breeder can obtain the warning information in the first time, which is convenient for quickly judging the health status of livestock and thus reducing losses; When replacing the feed tray 401, loosen the screw 404 on the fixing seat 403 to make the screw 404 disengage from the base 3. At this time, the fixing seat 403 and the base 3 are in an active state. Lift the fixing seat 403 to separate it from the base 3, and then remove the feed tray 401 from the base 3. When installing the feed tray 401, snap the feed tray 401 into the inside of the fixing seat 403.
