Abstract
Description
Technical Field
[0001] This utility model relates to the field of pig feed processing technology, and more specifically, it relates to a drying device for granular pig feed. Background Technology
[0002] Pelleted pig feed is a processed feed specifically designed for pigs. It is made by mixing various raw materials (such as corn, soybean meal, wheat, additives, etc.) into pellets through a specific process.
[0003] Drying pelleted pig feed is a crucial step in the production process, directly impacting feed quality, shelf life, and storage performance. The drying process primarily aims to remove excess moisture from the feed pellets, prevent mold growth and nutrient loss, and ensure the stability of the feed's physical structure.
[0004] The pelleted feed is fed into the drying chamber, where a stirring rod stirs the feed and a heating element heats it to evaporate the surface moisture.
[0005] The drying drum only has one set of stirring rods, which may cause uneven drying of the feed pellets due to the four corners of the rods. This affects the drying effect. In addition, the feeding speed of the existing drying drum is either too fast or too slow, making it difficult to control and thus affecting the drying effect. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] To address the problems existing in the prior art, this utility model provides a granular pig feed drying device to solve the technical problem mentioned in the background art where the feeding speed of the existing drying drum is either too fast or too slow, making it difficult to control the speed and thus affecting the drying effect.
[0008] Technical solution
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A pelleted pig feed drying device includes a base plate, two sets of support seats at the top of the base plate, a drying drum rotatably mounted on the two sets of support seats, a discharge pipe connected to the lower right side of the drying drum, a discharge valve mounted on the discharge pipe, four sets of legs at the bottom of the base plate, a guide pipe rotatably mounted in the middle of the left side of the drying drum, a feeding box at the input end of the guide pipe, a feed pipe connected to the top of the feeding box, three sets of legs evenly mounted on the outside of the feeding box, the bottom ends of the three sets of legs connected to the base plate, a first motor mounted at the top of the feeding box, a spiral conveying roller rotatably mounted inside the feeding box, the output end of the first motor passing through the top of the feeding box and connected to the spiral conveying roller, two sets of rotating shafts rotatably mounted inside the base plate, each set of rotating shafts having multiple sets of stirring blades, each set of stirring blades having a heating rod, and a toothed ring mounted in the middle of the outer end of the drying drum.
[0011] This invention is further configured such that each of the two sets of rotating shafts has a sprocket extending through the right end of the drying barrel to its outer side, and a chain is meshed on the two sets of sprockets. A motor frame is provided at the right end of the drying barrel, and a second motor is provided inside the motor frame. The output end of the second motor is connected to the right end of one set of rotating shafts. By turning on the second motor, the second motor drives one set of rotating shafts to rotate, which in turn drives the other set of rotating shafts to rotate under the action of the two sets of sprockets and chains. Multiple sets of stirring blades on the two sets of rotating shafts stir the feed in the drying barrel, and multiple sets of heating rods heat the multiple sets of stirring blades and feed, thereby drying the feed. This allows the multiple sets of stirring blades and heating rods on the two sets of rotating shafts to stir and dry the feed, improving its drying efficiency and effect.
[0012] The present invention is further configured such that a base is provided at the top of the bottom plate, a third motor is provided on the base, and a gear is provided at the output end of the third motor. The gear meshes with a gear ring. By turning on the third motor, the third motor drives the gear to mesh with the gear ring, which in turn drives the drying barrel to rotate as a whole. The drying barrel then drives the feed inside to turn over, which can fully turn the feed over and heat it evenly, further improving its drying effect.
[0013] The present invention is further configured such that the bottom ends of the four sets of support legs are connected to a storage groove, and each of the four sets of storage grooves is equipped with a hydraulic cylinder. Each of the four sets of hydraulic cylinders has a roller at its output end. When it is necessary to move the base plate as a whole, the four sets of hydraulic cylinders are activated, which drives the four sets of rollers to extend out of the four sets of support legs to support the base plate. Then, the four sets of rollers rotate to move the base plate as a whole. After the base plate has moved to the designated position, the four sets of hydraulic cylinders are activated in reverse, which drives the four sets of rollers to retract into the four sets of support legs. The four sets of support legs then support and fix the base plate, facilitating the movement of the base plate as a whole.
[0014] The present invention is further configured such that annular sliders are provided on the left and right sides of the outer wall of the drying barrel, and sliding grooves are provided on the inner sides of the two sets of support seats. The two sets of annular sliders slide in the two sets of sliding grooves. When the drying barrel rotates, the two sets of annular sliders slide on the two sets of support seats, which can improve the stability of the drying barrel when it rotates.
[0015] The present invention is further configured such that a vertical plate is provided at the top of the base plate, and the output end of the third motor is rotatably connected to the vertical plate, which can support the output end of the third motor, thereby improving the stability of the gear.
[0016] The present invention is further provided that a support plate is provided in the lower part of the feeding box, and the support plate is rotatably connected to the bottom of the spiral conveying roller, which can play a supporting role for the spiral conveying roller and improve the stability of the spiral conveying roller.
[0017] The present invention is further configured such that the multiple sets of stirring blades on the two sets of rotating shafts are arranged in an alternating manner, which can improve the stirring and drying effect of feed.
[0018] Beneficial effects
[0019] Compared with the prior art, the present invention provides a drying device for granular pig feed, which has the following beneficial effects:
[0020] 1. A drying barrel is rotatably mounted on both sets of support bases. A guide pipe is rotatably mounted on the middle of the left end of the drying barrel. A feeding box is mounted at the input end of the guide pipe. A spiral conveying roller is rotatably mounted inside the feeding box. The output end of the first motor passes through the top of the feeding box and is connected to the spiral conveying roller. Pellets are introduced into the feeding box through the feed pipe. Then, the first motor is turned on, which drives the spiral conveying roller to rotate. The spiral conveying roller then evenly introduces the feed into the drying barrel through the guide pipe. This facilitates the control of the granular feed being introduced into the drying barrel at a uniform speed, thereby providing a good drying effect for the feed.
[0021] 2. Two sets of rotating shafts are rotatably installed inside the base plate. Each set of rotating shafts is equipped with multiple sets of stirring blades, and each set of stirring blades contains a heating rod. The right side of each set of rotating shafts extends through the right end of the drying barrel and is equipped with a sprocket. Chains are meshed on the two sets of sprockets. The output end of the second motor is connected to the right end of one set of rotating shafts. By turning on the second motor, the second motor drives one set of rotating shafts to rotate. Under the action of the two sets of sprockets and chains, the other set of rotating shafts is driven to rotate. The multiple sets of stirring blades on the two sets of rotating shafts stir the feed in the drying barrel, and the multiple sets of heating rods heat the multiple sets of stirring blades and feed, thereby drying the feed. This allows the multiple sets of stirring blades and heating rods on the two sets of rotating shafts to stir and dry the feed, improving the drying efficiency and effect.
[0022] 3. A toothed ring is provided at the middle of the outer end of the drying barrel, and a gear is provided at the output end of the third motor. The gear meshes with the toothed ring. When the third motor is turned on, the third motor drives the gear to mesh with the toothed ring, which in turn drives the entire drying barrel to rotate. The drying barrel then causes the feed inside to turn over, which can fully turn the feed over and heat it evenly, further improving its drying effect. Attached Figure Description

The first motor 11 drives the spiral conveying roller 12 to rotate, and the spiral conveying roller 12 guides the feed evenly through the guide bend pipe 7 into the drying barrel 3. This makes it easy to control the granular feed to be introduced into the drying barrel 3 at an equal and uniform speed, thereby providing a drying effect for the feed.
[0034] Please see Figure 2 , Figure 3 and Figure 5 As one embodiment of the rotating shaft 13, in this utility model, the right side of both sets of rotating shafts 13 extends through the right end of the drying barrel 3 to its outside and is provided with a sprocket 17.

Sliding grooves are provided on the inner sides of the two sets of support seats 2, and the two sets of annular sliders 26 slide in the two sets of sliding grooves.
[0037] Specifically, by turning on the third motor 22, the third motor 22 drives the gear 23 to mesh with the gear ring 16, and the gear ring 16 drives the drying barrel 3 to rotate as a whole. The drying barrel 3 then drives the feed inside to turn over, which can fully turn the feed over and heat it evenly, further improving its drying effect. When the drying barrel 3 rotates, the two sets of annular sliders 26 slide on the two sets of support seats 2, which can improve the stability of the drying barrel 3 when it rotates.
[0038] Please refer to Figure 4 As a further implementation of the support leg 6: the bottom ends of the four sets of support legs 6 are connected to a storage groove, and each of the four sets of storage grooves is equipped with a hydraulic cylinder 24, and the output end of each of the four sets of hydraulic cylinders 24 is equipped with a roller 25.
[0039] Specifically, when it is necessary to move the base plate 1 as a whole, four sets of hydraulic cylinders 24 are activated. The four sets of hydraulic cylinders 24 drive four sets of rollers 25 to extend out from the four sets of support legs 6 to support the base plate 1. Then, the four sets of rollers 25 rotate to move the base plate 1 as a whole. After the base plate 1 has moved to the designated position, the four sets of hydraulic cylinders 24 are activated in reverse. The four sets of hydraulic cylinders 24 drive the four sets of rollers 25 to retract into the four sets of support legs 6. The four sets of support legs 6 then support and fix the base plate 1, making it easier to move the base plate 1 as a whole.
[0040] The present invention has a vertical plate 27 at the top of the base plate 1, and the output end of the third motor 22 is rotatably connected to the vertical plate 27, which can support the output end of the third motor 22, thereby improving the stability of the gear 23.
[0041] The present invention provides a support plate 28 in the lower part of the feeding box 8. The support plate 28 is rotatably connected to the bottom of the spiral conveying roller 12, which can support the spiral conveying roller 12 and improve the stability of the spiral conveying roller 12.
[0042] In this invention, multiple sets of stirring blades 14 on two sets of rotating shafts 13 are arranged in an alternating pattern, which can improve the stirring and drying effect of feed.
[0043] In summary, when using the overall equipment:
[0044] When it is necessary to dry the pelleted feed, the pelleted feed is introduced into the feed box 8 through the feed pipe 9 via the conveying device. Then the first motor 11 is turned on, which drives the spiral conveying roller 12 to rotate. The spiral conveying roller 12 evenly guides the feed into the drying barrel 3 through the guide pipe 7.
[0045] After the feed is introduced into the drying drum 3, the second motor 19 is turned on. The second motor 19 drives one set of rotating shafts 13 to rotate. Under the action of two sets of sprockets 17 and chains 18, it drives another set of rotating shafts 13 to rotate. Multiple sets of stirring blades 14 on the two sets of rotating shafts 13 stir the feed in the drying drum 3. Multiple sets of heating rods 15 heat the multiple sets of stirring blades 14 and the feed, thereby drying the feed.
[0046] By turning on the third motor 22, the third motor 22 drives the gear 23 to mesh with the gear ring 16, which in turn drives the drying barrel 3 to rotate as a whole. The two sets of annular sliders 26 slide on the two sets of support seats 2, which in turn causes the feed inside the drying barrel 3 to turn over, thereby improving the drying effect of the feed.
[0047] When the base plate 1 needs to be moved as a whole, the four sets of hydraulic cylinders 24 are activated. The four sets of hydraulic cylinders 24 drive the four sets of rollers 25 to extend out of the four sets of support legs 6 to support the base plate 1. Then, the four sets of rollers 25 rotate to move the base plate 1 as a whole. After the base plate 1 has moved to the designated position, the four sets of hydraulic cylinders 24 are activated in reverse. The four sets of hydraulic cylinders 24 drive the four sets of rollers 25 to retract into the four sets of support legs 6, and the four sets of support legs 6 support and fix the base plate 1.
