Technical Field
[0001] This utility model relates to a livestock feed drying device, belonging to the technical field of drying equipment. Background Technology
[0002] In livestock farming, the quality of stored forage directly affects breeding costs and livestock health. Fresh forage (such as corn stalks) has a high moisture content and is prone to mold if stored directly; therefore, it needs to be dried to reduce the moisture content. Existing forage drying equipment mostly uses a fixed oven structure, requiring the forage to be put in and taken out, increasing labor intensity and resulting in low drying efficiency. Some methods utilize rotary drying drums, but these have the following problems: The drying drum support components, such as idler rollers and support shafts, are exposed to hot air for a long time, which can easily lead to accelerated wear and shorten their service life. The two ends of the support shaft are installed via bearing seats, making installation and disassembly inconvenient. Utility Model Content
[0003] This invention provides a livestock feed drying device to solve the problems existing in the background art.
[0004] This utility model relates to a livestock feed drying device, including a base and a drying drum. A feed hood and a discharge hood, fixed to the base, are rotatably mounted at both ends of the drying drum. The drying drum is inclined with the feed end higher than the discharge end. Hot air inlet pipe and hot air outlet pipe are respectively provided on the feed hood and discharge hood. Support rings are fixed to the outer walls of both ends of the drying drum. A gear ring is fixed to the drying drum between the two support rings. A drive gear meshes with the lower part of the gear ring. The drive gear is rotatably mounted on the base and connected to a drive mechanism. Support rollers are provided on the lower front and rear sides of the two support rings. A limiting conical roller is rotatably mounted on the base on the side of the support ring near the discharge hood. The side of the support ring near the discharge hood has a conical surface. A support shaft is rotatably mounted in the middle of the support roller. Support seats equipped with internal cooling chambers are provided at both ends of the support shaft. A semi-circular support groove that mates with the support shaft is provided on the top of the support seat. Cooling holes are provided inside the support shaft. A positioning liquid delivery pipe connecting the cooling holes and the cooling chamber inside the support seat is fixed on the support groove.
[0005] As a preferred embodiment, a sealing ring is provided between the positioning infusion tube and the cooling hole, and a support slope with an outer higher angle and an inner lower angle is provided on the top inner side of the support base, with a support groove located on the upper part of the support slope. The sealing ring enhances the sealing performance between the positioning infusion tube and the cooling hole, preventing coolant leakage and ensuring the continuous and efficient operation of the cooling system; the outer higher angle and inner lower angle of the support slope optimizes the support angle of the support base on the support shaft, making the pressure at both ends of the support shaft basically perpendicular to the support slope, resulting in a better clamping effect.
[0006] As a preferred embodiment, the bottom of the support base is fixed with a sealed coolant tank that connects to the cooling chamber. The base has an opening for placing the coolant tank, and the lower part of the coolant tank is connected to coolant inlet and outlet pipes. A tightening bolt is located on the rear side of the support base, and the tightening bolt is threadedly connected to an adjusting threaded sleeve, which is fixed to the base. The sealed coolant tank can store sufficient coolant, and the coolant inlet and outlet pipes facilitate coolant replenishment and replacement, ensuring efficient cooling system circulation and preventing cooling failure due to insufficient coolant. The opening provides positioning space for the coolant tank, simplifying the installation process. The cooperation between the tightening bolt and the adjusting threaded sleeve allows for flexible adjustment of the support base's front and rear positions, facilitating precise adaptation of the support rollers according to the support ring position.
[0007] As a preferred embodiment, the drive mechanism includes a drive motor fixed on the base, the drive motor is connected to a reducer, and the output shaft of the reducer is connected to a drive gear via a coupling.
[0008] As a preferred embodiment, wear-resistant rubber sleeves are fixed to both ends of the drying drum. A flared sealing cover, fixed to the feed hood and discharge hood respectively, is fitted onto the outer side of each wear-resistant rubber sleeve. Both the feed hood and discharge hood have inlets and outlets for the ends of the drying drum to extend into. The inner wall of the sealing cover near the wear-resistant rubber sleeve is parallel to the drying drum. Multiple sealing rings are provided between the sealing cover and the wear-resistant rubber sleeve. The wear-resistant rubber sleeves enhance the wear resistance of the drying drum ends, preventing wear caused by friction between the drum and the inlet / outlet edges during rotation, thus extending the drum's service life. The flared sealing cover, in conjunction with the multiple sealing rings, significantly enhances the sealing performance at the connection between the drum and the feed hood and discharge hood, reducing hot air leakage and energy waste.
[0009] As a preferred embodiment, a baffle plate is fixed at the feed end of the drying drum to prevent the leakage of straw, and a feed hopper is fixed on the feed cover, with the lower end of the feed hopper extending into the drying drum through the center hole of the baffle plate.
[0010] As a preferred embodiment, the hot air inlet pipe and the hot air outlet pipe are respectively located on the top of the feed hood and the discharge hood, and a protective cover fixed to the base is provided on the outside of the gear ring to protect the gear ring.
[0011] This utility model has the following beneficial effects: The tilted setting of the drying drum, combined with its rotation, allows the hay to be evenly turned and moved toward the discharge end. During this movement, it comes into contact with hot air, ensuring sufficient heat exchange and improving drying efficiency. The cooling structure of the support shaft and support base can remove heat in real time, avoid high-temperature wear, extend the service life of the support components, and the two ends of the support shaft are placed in the semi-circular support groove and positioned by the positioning infusion tube, making the installation and disassembly of the support shaft relatively simple and convenient.
