Description

Technical Field

[0001] The utility model relates to the technical field of breeding equipment, in particular to an automatic quantitative feeding device for a pig farm. Background Art

[0002] Animal husbandry is the process of utilizing the physiological functions of domesticated animals such as livestock and poultry, or wild animals such as deer, musk deer, fox, mink, otter and quail, through artificial breeding and reproduction, to transform plant energy such as forage and feed into animal energy, so as to obtain livestock products such as meat, eggs, milk, wool, cashmere, hides, silk and medicinal materials. With the advancement of breeding technology, large-scale centralized animal husbandry has gradually matured. With the improvement of people's living standards, pork has become one of the important animal foods on people's tables.

[0003] Feeding pigs is a very important task faced by pig farmers. Pigs in different growth stages have different requirements for feed. Quantitative feeding is conducive to the healthy growth of pigs. A quantitative feeding device for pigs is disclosed in the Chinese utility model patent specification CN207461119U, including a quantitative cylinder, a hopper, a feed pipe and a feed trough arranged in sequence from top to bottom. The quantitative cylinder includes a cylinder body and a cover body at the upper end of the cylinder body. The discharge port is located at the lower end of the cylinder body. The discharge port is provided with a circular sealing plug, which is connected to a pull rope extending outward through the cover body. A feed port is provided at the top of the cover body, and the cover body is directly below the feed port. A cover unloading chamber is arranged on the side of the cover body, and a component installation chamber is arranged on the side of the cover body unloading chamber. A sealing slide plate is installed between the left and right horizontal slide grooves of the cover body, and the sealing slide plate extends from the component installation chamber through the long strip through hole of the cover body partition to the cover body unloading chamber. A gear is arranged in the component installation chamber through a transmission shaft, and a rack meshing with the gear is arranged at the lower end of the sealing slide plate. The transmission shaft is connected with a hand wheel on the outside of the cover body, which solves the demand for quantitative feeding of pigs. However, for large-scale pig farming, workers are still required to turn the hand wheel one by one to control each quantitative feeding device, and automatic quantitative feeding cannot be realized. The workers have a large workload and the efficiency is low. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, the utility model provides an automatic quantitative feeding device for a pig farm, comprising a barrel body 1, a barrel cover 2 is arranged on the top of the barrel body 1, a feed quantitative mechanism mounting plate 3 is arranged on the inner side of the top of the barrel body 1, a PLC controller 4 is arranged on the feed quantitative mechanism mounting plate 3, a rotating shaft passing hole 5 is arranged in the middle of the feed quantitative mechanism mounting plate 3, a feed quantitative mechanism 6 is rotatably connected to the rotating shaft through the hole 5 through a bearing, a longitudinal partition B7 is connected to one side of the feed quantitative mechanism mounting plate 3, a hopper 8 is arranged at the bottom of the barrel body 1, a discharge port 9 is opened at the bottom of the hopper 8, and a discharge pipe 10 is connected to the discharge port 9.

[0023] refer to Figure 1 , Figure 3 and Figure 3The feed quantitative mechanism 6 includes: a pressure sensor 601, a rotating shaft 602, a hand wheel 603, a rotating shaft motor 604, a gear 605, a rack 606, a partition 607, a winding groove 608, a pull rope 609 and a sealing plug 610; the pressure sensor 601 is fixed to the bottom of the inner wall of the hopper 8 and is electrically connected to the PLC controller 4, the rotating shaft 602 is rotatably fixed in the rotating shaft through hole 5, and the two ends of the rotating shaft 602 are respectively connected to the hand wheel 603 and the rotating shaft motor 604, and the rotating shaft motor 604 is fixed in the mounting seat on the rear side of the barrel body 1 and is electrically connected to the PLC controller 4. A wire winding groove 608 is provided in the center of the rotating shaft 602. A pull rope 609 is fixed in the wire winding groove 608. A sealing plug 610 is connected to the end of the pull rope 609. Gears 605 are fixed on the rotating shaft 602 at both ends of the wire winding groove 608. A partition 607 is installed above the rotating shaft 602. A rack 606 is provided at the bottom of the partition 607 where it contacts the gear 605. The rack 606 is coupled to the gear 605.

[0024] By setting up the feed quantitative mechanism 6, the feed enters the barrel through the feed port 201, and the pressure sensor 601 located at the bottom of the barrel detects the pressure value in the barrel. When the predetermined pressure is reached, a signal is sent to the PLC controller 4. The PLC controller 4 controls the shaft motor 604 to drive the shaft 602 to rotate, and the gear 605 fixed on the shaft 602 rotates, driving the rack 606 to move forward so that the partition 607 seals the barrel body unloading chamber 701 to prevent the feed from entering. At the same time, the shaft 602 rotates to drive the pull rope 609 to be wound in the winding groove 608, so that the sealing plug 610 is detached from the discharge port 9, and the feed is discharged from the discharge port 9, thereby realizing automatic quantitative feeding of the feed trough.

[0025] refer to Figure 1 and Figure 4 The unloading pipeline 10 includes a vertical pipeline 1001, a bending pipe 1002 and a discharge pipe 1003; the vertical pipeline 1001 is fixedly connected below the discharge port 9, and a bending pipe 1002 is connected below the vertical pipeline 1001. The bending angle of the bending pipe 1002 is 120°, and a layer of rubber buffer pad 1004 is covered on the inner wall of the bending pipe 1002. The discharge end of the bending pipe 1002 is connected to the discharge pipe 1003.

[0026] By arranging a bending pipe 1002 at the bottom of the feeding pipe 10, the feed falls downward along the vertical pipe 1001 after being discharged from the discharge port 9. The rubber buffer pad 1004 on the inner wall of the bending pipe 1002 cushions the feed and reduces the downward impact of the feed. At the same time, the bending angle of the bending pipe 1002 is 120°, which effectively avoids the accumulation of feed in the bending pipe 1002, thereby avoiding the situation where the feed splashes around when entering the feed trough.

[0027] The working principle and use process of the utility model are as follows: the feed barrel is fixed on the feed feeding pipe through the feed barrel fixing ring 205, and the feed enters from the feed inlet 201 and flows into the barrel body discharge chamber 701 along the cover body discharge chamber 203. As time goes by, the feed in the barrel body 1 increases, and the pressure in the barrel increases. When the pressure sensor 601 detects that the pressure value in the barrel reaches a predetermined pressure, it sends a signal to the PLC controller 4. The PLC controller 4 controls the shaft motor 604 to drive the shaft 602 to rotate, and the gear 605 fixed on the shaft 602 rotates, driving the rack 601 to rotate. 06 moves forward to extend the partition plate 607 to seal the barrel body discharge chamber 701, preventing the feed from entering. At the same time, the rotating shaft 602 drives the winding groove 608 to rotate, and the pull rope 609 is wound in the winding groove 608. As the winding groove 608 rotates, the sealing plug 610 is pulled out of the discharge port 9, and the feed is discharged from the discharge port 9 and falls downward along the vertical pipe 1001. When passing through the bending pipe 1002, the rubber buffer pad 1004 on the inner wall thereof cushions the feed, reducing the downward impact of the feed, so that the feed will not splash around when entering the trough.
