Description

Technical Field

[0001] The invention relates to the technical field of pig feed processing, in particular to a moisture-proof storage device for pig feed processing. Background Art

[0002] With the rapid development of the breeding industry, the demand for pig feed has increased year by year, especially higher requirements have been put forward for the quality and storage conditions of feed. In the storage and processing of pig feed, moisture-proof, mildew-proof and uniform mixing have become key technical issues. In the existing technology, some patent documents have proposed improved feed storage devices. For example, the patent document with publication number CN117141945A describes a moisture-proof storage device for livestock feed, which forms compartments through partitions to store different types of feed to prevent mixing, and drives the turntable to rotate through a rotating shaft so that the required feed compartment is located at the feed inlet. Although it saves construction costs and is convenient to use, in actual use, due to the long-term accumulation of feed, the bottom feed is prone to mildew due to moisture.

[0003] In addition, the mixing uniformity of feed is also an important issue during the storage process. Existing mixing devices generally use fixed stirring blades for mixing. Although they can achieve a certain degree of mixing effect, due to the large resistance encountered by the mixing blades during the processing, they often require a large power output, resulting in low energy efficiency and increased equipment wear. In addition, the feed is prone to stratification during storage, and the bottom layer of feed is often difficult to mix effectively due to long-term pressure, resulting in uneven feed.

DETAILED DESCRIPTION

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

[0022] Please refer to the attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides a moisture-proof storage device for pig feed processing, comprising a mounting base plate 1, a storage barrel 3 is arranged at the middle of the top of the mounting base plate 1, a support frame 2 is fixedly connected to one side of the top of the mounting base plate 1, a heating box 707 is fixedly connected to the top of the support frame 2, a connecting pipe 708 is connected to the outside of the heating box 707, a connecting pipe 706 is connected to the bottom of the heating box 707, a fixed cylinder 701 is fixedly connected to the top of the mounting base plate 1, a mounting cavity 704 is opened inside the fixed cylinder 701, a piston 705 is slidably connected to the inner wall of the mounting cavity 704, a movable rod 702 is fixedly connected to the outside of the piston 705, an air intake pipe 703 is connected to one side of the outside of the fixed cylinder 701, a knocking assembly is installed on the top of the storage barrel 3, and a small resistance mixing assembly is installed inside the storage barrel 3. One end of the connecting pipe 708 is rotatably connected to one end of the spline shaft 406, and one end of the connecting pipe 706 is connected to the outside of the fixed cylinder 701. One-way valves are installed inside the air inlet pipe 703 and the connecting pipe 706, and the flow directions of the two one-way valves are opposite.

[0023] Specifically, the storage barrel 3 is arranged at the middle of the top of the mounting base plate 1 for storing pig feed. A knocking assembly is installed on the top of the storage barrel 3 so as to regularly vibrate the feed during storage to prevent caking and help reduce the accumulation of moisture. The support frame 2 is used to support the heating box 707 and other related components. The heating box 707 is installed on the top of the support frame 2 and has a built-in electric heating wire. Its function is to heat the compressed air and convert it into hot air flow, which is used to heat the feed and evaporate the moisture therein. When the rack plate 604 starts to move, it drives the piston 705 to slide along the inner wall of the mounting cavity 704 to compress the air in the mounting cavity 704. The compressed air enters the heating box 707 through the connecting pipe 706. The air entering the heating box 707 is heated by the electric heating wire and becomes a hot air flow. The hot air flow is introduced into the cavity inside the spline shaft 406 through the connecting pipe 708. The hot air flow enters the feed pipe 5 through the outlet pipe and directly acts on the pig feed. The water in the feed is evaporated into moisture, and the hot air flow helps the water in the feed evaporate and dry it. After the moisture is evaporated, the sealing plate opens, and the exhaust fan starts to work, exhausting the moisture in the feed pipe 5, and preventing foreign matter from entering through the filter, further protecting the quality of the feed. The one-way valve design in the device ensures the one-way flow of the airflow, so that the air can only flow in the process of compressing, heating and drying the feed, thereby preventing the entry of external air and affecting the working efficiency of the system.

[0024] At the same time, in order to enable normal feeding, a feeding pipe (not shown in the figure) will be added to the outside of the storage barrel 3 during actual use. At the same time, a valve is installed on the outside of the feeding pipe to facilitate the removal of pig feed from the storage barrel 3.

[0025] The low resistance mixing assembly includes a motor 402, which is fixedly connected to the bottom of the storage barrel 3, and the output end of the motor 402 is fixedly connected to a rotating shaft 403, one end of the rotating shaft 403 is fixedly connected to a spline shaft 406, the outer surface of the spline shaft 406 is slidably connected to a spline sleeve 407, the outer side of the spline sleeve 407 is rotatably connected to a connecting shaft 404, and the outer side of the connecting shaft 404 is fixedly connected to a plurality of mixing blades 405, and the top of the storage barrel 3 is provided with a first cylinder 401, and the output end of the first cylinder 401 is fixedly connected to a rotating sleeve 408, and the rotating sleeve 408 is rotatably connected to the outer side of the spline sleeve 407. The interior of the spline shaft 406 is set as a cavity, and the outer surface of the spline shaft 406 is provided with a plurality of air outlet pipes at equal intervals.

[0026] Specifically, the motor 402 is fixedly connected to the bottom of the storage barrel 3, and the motor 402 is started to drive the rotating shaft 403 to rotate through the output end. The use of the motor 402 can effectively provide a power source to drive the operation of the entire mixing system. The rotating shaft 403 is fixedly connected to the motor 402 through the output end of the motor 402. The function of the rotating shaft 403 is to transmit the rotational power of the motor 402 to the spline shaft 406. One end of the rotating shaft 403 is fixedly connected to the spline shaft 406 to ensure the stable transmission of the driving force. The spline shaft 406 is connected to the rotating shaft 403 by a spline, allowing the spline sleeve 407 to slide freely on the spline shaft 406. The outer side of the spline sleeve 407 is connected to the connecting shaft 404. Through the mutual cooperation of the spline shaft 406 and the spline sleeve 407, the working resistance of the mixing blade 405 can be effectively reduced during the mixing process, and the efficient operation of the assembly is guaranteed.

[0027] The motor 402 is started to drive the rotating shaft 403 to rotate, thereby causing the spline shaft 406 and the spline sleeve 407 to move synchronously. Through this power transmission process, the mixing blade 405 starts to rotate and starts to stir the material. At the same time, the second cylinder 601 is started to drive the rack plate 604 to move back and forth along the inner wall of the limit plate 605, driving the driving gear 602 to swing forward and backward. The swing of the driving gear 602 drives the connecting shaft 603 to move, thereby controlling the flipping of the storage barrel 3. The flipping of the storage barrel 3 allows the mixing blade 405 to enter the bottom from the top of the feed pipe 5, driving the feed to flip and stir, ensuring that the feed is evenly mixed during the stirring process. During the flipping process, the mixing blade 405 stirs the flowing feed with lower resistance, thereby improving the mixing efficiency and reducing energy consumption. The first cylinder 401 drives the spline sleeve 407 to slide along the outer diameter direction of the spline shaft 406 through the rotating sleeve 408, adjusts the working position of the mixing blade 405, and makes the stirring more uniform and efficient.

[0028] The front and rear sides of the top of the installation base plate 1 are fixedly connected to the limit plate 605, the top side of the limit plate 605 is installed with the second cylinder 601, the output end of the second cylinder 601 is fixedly connected to the rack plate 604, the outside of the storage barrel 3 is rotatably connected to the connecting shaft 603, and the outside of the connecting shaft 603 is fixedly connected to the driving gear 602. The outside of the driving gear 602 is meshed and connected with the outside of the rack plate 604, and one side of the rack plate 604 is fixedly connected to one end of the movable rod 702.

[0029] Specifically, first, the function of the limit plate 605 is to limit the range of movement of the rack plate 604 in the front-to-back direction to prevent it from excessively moving and causing failure or damage to other components. A second cylinder 601 is installed on one side of the top of the limit plate 605. The main function of the second cylinder 601 is to drive the rack plate 604 to perform linear reciprocating motion along the inner wall of the limit plate 605. The second cylinder 601 realizes the linear displacement of the rack plate 604 by controlling the thrust of the output end. Since the second cylinder 601 has the ability to accurately control displacement, it can ensure the stability and efficiency of the rack plate 604 during operation and avoid motion errors caused by uneven or unstable displacement. The second cylinder 601 acts as a driving component, which drives the rack plate 604 to perform linear reciprocating motion, so that the rack plate 604 is meshed with the driving gear 602, thereby driving the connecting shaft 603 to rotate. The rotation of the connecting shaft 603 directly drives the storage barrel 3 to rotate.

[0030] The knocking assembly includes a first bevel gear 801, which is fixedly connected to the outside of the rotating shaft 403. The rotating shaft 803 is rotatably installed at the bottom of the storage barrel 3. One end of the rotating shaft 803 is fixedly connected to the second bevel gear 802. The other end of the second bevel gear 802 is fixedly connected to a fixed plate 804. Two fixed blocks 805 are fixedly connected to the outer eccentric part of the fixed plate 804. The bottom end of the storage barrel 3 is fixedly connected to a support plate 808. The inner side of the support plate 808 is connected to a swing rod 806 through a pin. A torsion spring is installed on the outer side of the pin. One end of the swing rod 806 is fixedly connected to a knocking ball 807. A knocking plate 809 is fixedly connected to one side of the bottom end of the storage barrel 3. The outer side of the first bevel gear 801 is meshed and connected with the outer side of the second bevel gear 802. The swing rod 806 is tilted.

[0031] Specifically, the motor 402 drives the rotating shaft 403 to rotate the first bevel gear 801. The first bevel gear 801 drives the second bevel gear 802 to rotate synchronously, and further drives the rotating shaft 803 and the fixed plate 804 to rotate. Due to the eccentric design of the fixed plate 804, the fixed block 805 contacts one end of the swing rod 806 during the rotation process and applies force, thereby driving the swing rod 806 to swing at a certain angle.

[0032] The swing rod 806 is connected to the support plate 808 via a pin, and a torsion spring is installed on the outer side of the pin. The elasticity of the torsion spring enables the swing rod 806 to return to its original position after being acted upon by an external force. This mechanical elastic system enables the swing rod 806 to perform periodic repetitive motion between the knocking ball 807 and the knocking plate 809, generating vibration.

[0033] The knocking ball 807, driven by the swing rod 806, continuously strikes the knocking plate 809, generating a rhythmic mechanical impact force. The vibration transmitted by the knocking plate 809 acts on the storage barrel 3, so that the feed and other materials in the barrel are loosened during the vibration process, thereby avoiding the occurrence of caking. Through this vibration, the feed in the storage barrel 3 maintains good fluidity, thereby ensuring the storage quality and use efficiency of the feed.

[0034] A feed pipe 5 is fixedly connected to one side of the top of the storage barrel 3, a sealing cover is installed on the top of the feed pipe 5, a filter plate and an exhaust fan are installed inside the sealing cover, and a heating wire is installed inside the heating box 707, and the heating wire is powered by an external power supply.

[0035] Specifically, the filter plate is designed with different apertures or materials according to the type of material and processing requirements to achieve the best filtering effect. The exhaust fan works with the filter plate. The exhaust fan is located in the sealing cover. Its main function is to ensure that the waste gas or hot gas generated during the material processing process is discharged to the external environment in time by sucking and discharging air, so as to prevent the internal pressure of the system from being too high or accumulating too much waste gas and affecting the operation of the equipment.

[0036] A heating wire is installed inside the heating box 707 to heat the material in the storage barrel 3. The heating wire is powered by an external power supply, and the material of the heating wire is usually an alloy with good resistance characteristics or a high-temperature resistant metal to ensure a stable and lasting heating effect. The outside of the heating box 707 has a heat insulation layer to reduce heat loss and improve energy efficiency.

[0037] Working principle: When using the device, first start the motor 402 to drive the rotating shaft 403 to rotate, so that the spline shaft 406 and the spline sleeve 407 move synchronously. At this time, start the second cylinder 601 to drive the rack plate 604 to move back and forth along the inner wall of the limit plate 605. During the movement of the rack plate 604, the driving gear 602 is driven to swing forward and backward. During the swinging of the driving gear 602, the connecting shaft 603 is driven to move synchronously, so that the storage barrel 3 is driven to rotate. When the storage barrel 3 is just turned over, the connecting shaft 404 and the mixing blade 405 are located in the inlet. The top of the feed pipe 5, and the pig feed is located at the bottom of the feed pipe 5. During the 180-degree flipping process, the stirring assembly composed of the connecting shaft 404 and the mixing blades 405 is located at the bottom of the feed pipe 5, and the feed is located at the top of the feed pipe 5. In this way, the stirring assembly runs through the entire feed. At this time, the mixing blades 405 will stir and mix the feed in a flowing state, greatly reducing the resistance of the mixing blades 405 in the feed. In addition, by starting the first cylinder 401 to drive the spline sleeve 407 to move along the outer diameter of the spline shaft 406, the position of the stirring assembly is moved to improve the mixing degree of the feed; When the rack plate 604 moves, it will drive the movable rod 702 and the piston 705 to move along the inner wall of the installation cavity 704, so that the internal air of the installation cavity 704 is compressed and enters the interior of the heating box 707 through the connecting pipe 706. The gas is heated by the electric heating wire inside the heating box 707 and becomes a hot air flow. The hot air flow is injected into the cavity inside the spline shaft 406 through the connecting pipe 708, and the air flow is discharged into the interior of the feeding pipe 5 through the air outlet pipe to dry the pig feed. The hot air heats the pig feed to generate moisture. The sealing plate is opened to use the exhaust fan to discharge the moisture inside the feeding pipe 5. At the same time, a filter is used to prevent external foreign matter from entering the interior of the feeding pipe 5, thereby improving the dehumidification effect of the pig feed. Finally, as the output end of the motor 402 rotates, the first bevel gear 801 will be driven to rotate synchronously, thereby driving the meshing second bevel gear 802 to rotate synchronously, and further driving the rotating shaft 803 and the fixed plate 804 to rotate coaxially, so that the fixed block 805 continuously contacts and squeezes one end of the swing rod 806. Under the spring action of the pin shaft and the torsion spring, the swing rod 806 drives the knocking ball 807 to continuously knock the outer wall of the plate 809, thereby vibrating the storage barrel 3. This can effectively prevent the storage barrel 3 from agglomerating, keep the pig feed in a loose state, and help improve the storage quality and utilization efficiency of the feed.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
