Description

Technical Field

[0001] The invention relates to agricultural breeding technology, in particular to a quantitative feeding device for piglets. Background Art

[0002] Every time a traditional pig farm feeds pigs, pig feed must be added to the trough manually or by equipment. Patent No. CN201921835147.7 discloses a pig feed feeding device. The document mentions that during the feeding process, uneven distribution of feed in the pig trough is prone to occur. When the feed is unevenly distributed, there will be a problem of snatching food, which will also cause the pigs to bite and fight. The document can maintain uniform distribution of feed in a single pig trough. In the prior art, most pig troughs are single troughs. When there are more pigs in the pigpen, the single trough will cause the piglets in the back row to be unable to eat, which will cause disharmony in the pig herd.

[0003] Patent No. CN202122017662.8 discloses a double-trough feeding device for pigs, and Patent No. CN201811138670.4 discloses a double-trough feeding device for pigs and a method of use. The document describes feeding feed to a double-trough pigpen, improving the existing single trough to a double trough, which can support more piglets to eat at the same time, but the feeding device is too large and more troublesome to operate. Moreover, the feed is put into the trough at one time during feeding. If the pigpen does not finish eating in the first time, the remaining feed will be oxidized and contaminated, and it is impossible to feed accurately according to the piglet's appetite.

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0041] like Figure 1 As shown, the quantitative feeding device for piglet feed of the present invention comprises a supporting component 1, a connecting component 2, and a pig trough 30, wherein the supporting component 1 specifically comprises a supporting leg 11 and a connecting plate 12. The supporting leg 11 is fixed inside the pig pen, and the connecting plate 12 is fixedly connected to the supporting leg 11 by bolts. The connecting component 2 is fixedly connected to both sides of the pig trough 30 by bolts, wherein the connecting component 2 at one end is fixedly connected to the connecting plate 12, and the other end can be used as a series of pig troughs 30, and the two pig troughs 30 are fixedly connected by bolts, and the supporting components 1 on both sides of the pig trough 30 are used to fix the pig trough 30. The pig troughs 30 are arranged in double rows on both sides of the supporting component 1, which increases the number of piglets fed at the same time and avoids the situation where the piglets in the back row cannot eat, which will lead to the situation where the pigs are not in harmony and bite each other.

[0042] The figure shows only five pig troughs 30 on both sides. In actual application, the number of pig troughs can be adjusted according to the size of the pig pen. The upper end of the pig trough 30 is opened for connecting a feeding device (not shown in the figure). The pig trough 30 is 250mm±5mm away from the ground of the pig pen, which can prevent feces, urine and flushing water in the pig pen from splashing into the pig trough.

[0043] The connection on the connecting member 2 is an arc-shaped structure, and a plurality of bolts can be installed on the arc-shaped structure. To prevent the piglets from overturning the pig trough during eating, the arc-shaped structure on the connecting member 2 can have a better bearing capacity.

[0044] like Figures 2 to 6As shown, the pig trough 30 in the quantitative feeding device for piglet feed of the present invention includes a trough frame 31, a rotating shaft 32, a baffle 33, a filter 331, a torsion spring 34 and a turntable 35. The trough frame 31 is fixed to the connecting plate 12 by a connecting component 2. The trough frame 31 is a trapezoidal hollow structure, and the upper opening can also be connected to an external feeding device. The bottom of the trough frame 31 is an arc structure, and the arc structure at the bottom can avoid uneven distribution of feed when it falls. An inclined plate is provided inside the frame, and inclined guide grooves and a plurality of mounting threaded holes are provided on both sides. Two slide grooves are provided inside, and bearings are installed on both sides of the slide grooves to facilitate the subsequent installation of other components.

[0045] The rotating shaft 32 is rotatably connected to the trough frame 31, the baffle 33 is fixedly connected to the rotating shaft 32, a row of columnar grooves are formed on the baffle 33, and a filter screen 331 is fixed on the columnar grooves. A rotating disk 35 is fixedly connected to both sides of the rotating shaft 32, and a torsion spring 34 is provided between the rotating disk 35 and the trough frame 31. Figure 5 As shown, a small gear bar is also provided on the trough frame 31 to prevent the torsion spring 34 from being irreversibly damaged.

[0046] Among them, the baffle 33 is used to prevent the feces, urine and flushing water in the pigsty from splashing into the trough frame 31, ensuring the cleanliness of the feed and effectively preventing the occurrence of piglet diseases. When the piglets need to eat, the piglets push the baffle 33 so that the baffle 33 rotates counterclockwise into the trough frame 31. The pig feed inside the trough frame 31 is exposed for the piglets to eat. When there is no need to eat, the baffle 33 is reset under the action of the torsion spring 34. A row of columnar grooves is opened on the baffle 33, and its function is to allow the smell of the feed in the trough frame 31 to dissipate and attract the pigs to eat. The filter 331 on the baffle 33 prevents pollutants from entering the trough frame 31 through the columnar grooves.

[0047] like Figures 2 to 11 As shown, the pig trough 30 in the quantitative feeding device for piglet feed of the present invention also includes a limit assembly 50, an opening and closing assembly 60, and a trigger assembly 70. Among them, the limit assembly 50 is located on the end face of the trough frame 31, and the limit assembly 50 includes an arc bracket 51, an arc rod 52, an electromagnetic rod 53, a first reset spring 54, and a magnet plate 55. A pair of arc brackets 51 are fixedly connected to the trough frame 31 by bolts, the arc rod 52 is slidably connected to the arc bracket 51, a first reset spring 54 is connected between the arc rod 52 and the arc bracket 51, a pair of electromagnetic rods 53 are fixedly connected to the arc rod 52, and the magnet plate 55 is fixed on one of the end faces of the trough frame 31, and the electromagnetic rod 53 and the magnet plate 55 are repelling each other with the same poles. As shown Figure 6 As shown, the rotating disk 35 is provided with an arc groove 40, and one end surface of the arc groove 40 is a horizontal surface. The rotating disk 35 is fitted with the arc rod 52, and the first return spring 54 is in a compressed state.

[0048] like Figure 5 As shown, when the baffle 33 rotates counterclockwise over 75°, the arc groove 40 on the rotating disk 35 faces upward, and the arc rod 52 slides into the arc groove 40 under the action of the first return spring 54 in a compressed state, and the arc rod 52 limits the rotation angle of a horizontal end surface on the arc groove 40, so that the baffle 33 is limited at the rotation angle. This prevents the baffle 33 from resetting under the action of the torsion spring and scaring the piglets eating.

[0049] In the prior art, the feed in the pig trough is added by the breeder or other equipment at one time. Although this method is more convenient and saves time and effort, if the piglets do not eat all the feed at once, some of the remaining feed will be contaminated. After the piglets eat for the second time, it is easy to cause diseases. In this regard, the opening and closing component of the present invention can accurately distribute the feed into the trough frame, ensuring that the feed is clean and hygienic every time the piglets eat.

[0050] Among them, Figures 9 and 10 As shown, the opening and closing assembly 60 is located on both sides of the trough frame 31, and the opening and closing assembly 60 includes a missing gear 61, a fixed ring 62, a sliding rod 63, a rack 64, a second return spring 65, a limit slot plate 66, an opening and closing plate 67, and a third return spring 68. The missing gear 61 is fixedly connected to the turntable 35, the fixed ring 62 is fixedly connected to the trough frame 31, the sliding rod 63 is slidably connected to the fixed ring 62 via the second return spring 65, the sliding rod 63 is fixedly connected to the rack 64, and the limit slot plate 66 is fixed to the sliding rod 63. The limit slot plate 66 is tightly fitted with the side of the trough frame 31, and its purpose is to prevent pig feed from leaking from the slot on the side of the trough frame 31. Among them, the missing gear 61 is meshed with the rack 64.

[0051] like Fig. 9 As shown, the opening and closing plate 67 is slidably connected in the oblique guide groove on the trough frame 31, one end of the third return spring 68 is connected to the opening and closing plate 67, and the other end is connected to the trough frame 31. The round rod on the opening and closing plate 67 slides horizontally on the limit groove plate 66, and the limit groove plate 66 reciprocates up and down to make the opening and closing plate 67 move along the oblique guide groove on the trough frame 31.

[0052] When the rotating disk 35 drives the missing gear 61 to rotate counterclockwise through the baffle 33, the missing gear 61 meshes with the rack 64, driving the rack 64 and the sliding rod 63 to move upward, and the second return spring 65 is compressed. The sliding rod 63 drives the limit slot plate 66 to move upward, so that the opening and closing plate 67 slides along the oblique guide groove on the trough frame 31. The opening and closing plate 67 is opened, and the feed above the trough frame 31 slides to the bottom of the trough frame 31. Each time the piglet pushes the baffle 33, the opening and closing assembly 60 opens and closes once, realizing the feed differentiation and accurate feeding, avoiding the contamination of excess feed, so that the piglet becomes sick.

[0053] like Figures 11 to 14 As shown, the trigger assembly 70 is located at the back of the trough frame 31, and the trigger assembly 70 includes an adjustment structure 71, a trigger structure 72, and a fifth reset spring 73. Among them, the adjustment structure 71 is located on one side of the slide groove at the back of the trough frame 31. The adjustment structure 71 is composed of a rotating rod 711 and an arc plate 712. The rotating rod 711 is rotatably connected to the back of the trough frame 31 through a bearing, and the arc plate 712 is fixedly connected to the back of the trough frame 31 by bolts, and a plurality of adjustment holes are opened on the arc plate 712. The rotating rod 711 is fixedly connected to the arc plate 712 by bolts, and the inclination angle of the rotating rod 711 can be adjusted according to actual use.

[0054] The trigger structure 72 is slidably connected to the slide groove on the trough frame 31 via the fifth return spring 73. Figure 13 to Figure 14 As shown, the trigger structure 72 mainly consists of a trigger plate 721, a slide bar 722, a fourth reset spring 723, and a travel switch 724. The trigger plate 721 is slidably connected in the slide groove on the trough frame 31, and the stop bar on the trigger plate 721 is tightly fitted with the trough frame 31 to prevent feed from leaking out. The slide bar 722 is slidably connected in the slot of the trigger plate 721. The slide bar 722 is connected to the fourth reset spring 723 between the trigger plates 721, and the fourth reset spring 723 is in a compressed state. The travel switch 724 is arranged in the slot of the trigger plate 721.

[0055] When the round rod on one end of the slide bar 722 is fitted with the travel switch 724, the travel switch 724 controls the electromagnetic rod 53 to be energized for 30 seconds. The arc head on the other end of the slide bar 722 is tightly fitted with the rotating rod 711.

[0056] When the opening and closing assembly 60 is opened and closed once under the action of the baffle 33, during the process of the feed sliding from the top of the trough frame 31 to the bottom of the trough frame 31, part of the feed will push the trigger plate 721 to move downward, the slide rod 722 is no longer in contact with the rotating rod 711, the fourth reset spring 723 is reset, the round rod on one end of the slide rod 722 is separated from the travel switch 724, and the fifth reset spring 73 is compressed.

[0057] After the piglet has eaten all the feed in the trough frame 31 and on the trigger plate 721, the trigger plate 721 is reset under the action of the fifth reset spring 73, and the slide 722 moves upward to compress the fourth reset spring 723 under the action of the rotating rod 711. When the round rod on one end of the slide rod 722 fits with the travel switch 724, the travel switch 724 controls the electromagnetic rod 53 to be energized for 30 seconds. After the electromagnetic rod 53 is energized, it repel each other with the magnet plate 55, and the electromagnetic rod 53 drives the arc rod 52 to move upward and separate from the turntable 35. When the turntable 35 is no longer restricted by the arc rod 52, it drives the baffle 33 to reset under the action of the torsion spring 34, that is, the device returns to the initial state. Through the trigger assembly 70 in the quantitative feeding device for piglet feed of the present invention, it can be achieved that after the piglet finishes eating, the baffle 33 can be quickly returned to its position to prevent pollutants from entering the interior of the trough frame 31, thereby ensuring the cleanliness of the feed that leaks next time.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
