Description

Technical Field

[0001] This application relates to the field of feed processing, and more specifically, to a livestock feed mixer. Background Technology

[0002] A livestock feed mixer is a type of machinery specifically designed for livestock farming. Its core function is to uniformly mix various feed ingredients (such as grains, soybean meal, minerals, vitamins, etc.) according to a formula ratio. It is one of the key pieces of equipment in modern farming to ensure feed quality and improve farming efficiency.

[0003] Chinese patent application number 201720645208.8 discloses a mixer for livestock feed processing, including a housing, a mixing drum, a mesh cover, a hot air blower, a hot air conveying pipe, and a stirring rod. The mixing drum is located inside the housing, with a rotary motor connected to its bottom. A stirring device is located at the top of the housing, containing a stirring motor. The output shaft of the stirring motor is connected to the stirring rod via a bushing, and the stirring rod contains a hollow pipe. This invention, by setting the rotation direction of the stirring motor in the stirring device to be opposite to the rotation direction of the rotary motor in the mixing drum, facilitates thorough and uniform mixing of the raw materials in the mixing drum. The hollow pipe and vent holes within the stirring rod facilitate the drying of the raw materials in the mixing drum using the hot air blower, preventing the raw materials from clumping and adhering to the drum wall. Furthermore, the mesh cover around the vent holes prevents raw materials from entering the hollow pipe through the vent holes.

[0004] The above-mentioned solution has the following shortcomings: The existing device uses a hollow pipe and a hot air blower to mix and dry the raw materials at the same time. However, the feed for different livestock and poultry at different growth stages varies. Different shapes of mixing blades are required for pelleted feed, fiber feed, and high-moisture feed in order to better ensure the uniformity of mixing. Therefore, it needs to be improved. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a livestock feed mixer, which aims to improve the problems of inconvenient replacement of mixing devices and difficulty in uniformly mixing different feeds due to the single shape of the mixing blade.

[0006] This application provides a livestock feed mixer, including a carrying tank for carrying feed and a top cover. The top of the top cover is provided with a connecting seat for connection. A drive motor is installed above the connecting seat. The output end of the drive motor is fixed with a mounting sleeve extending into the connecting seat. A mixing frame is installed at the bottom of the top cover, extending into the carrying tank and docking with the mounting sleeve.

[0007] In one specific embodiment, the top of the stirring rack is provided with a rod for insertion into the mounting sleeve. Both the rod and the surface of the mounting sleeve are provided with corresponding connecting through holes, wherein a limit bolt is inserted into the connecting through hole of the rod and the mounting sleeve.

[0008] In the above process, the mixing rack can be detachably fixed by the cooperation of the insert rod, the mounting sleeve and the limit bolt, which facilitates the disassembly, repair or replacement of the mixing rack and improves the convenience of equipment maintenance.

[0009] In one specific implementation, the bottom of the drive motor is provided with a connecting plate, and the drive motor is bolted to the top of the connecting seat through the connecting plate, wherein the output end of the drive motor extends into the connecting plate, and the opening end of the mounting sleeve fixed to the output end of the drive motor extends to the inner top of the top cover.

[0010] In the above process, the drive motor is securely fixed to the connecting seat by the connecting plate to ensure precise docking between the mixing rack and the drive motor, avoid deviation or shaking during power transmission, and ensure the stability of the mixing operation.

[0011] In one specific implementation, the top cover is provided with a rotating shaft bracket and a locking block in opposite directions at its edges, wherein the top edge of the bearing tank is provided with a buckle and a rotating shaft seat that cooperate with the rotating shaft bracket and the locking block in opposite directions at its edges.

[0012] In the above process, the mechanical basis for opening and closing of the top cover is provided by the cooperation of the rotating shaft frame, the locking block and the buckle, and the rotating shaft seat.

[0013] In one specific implementation, the top cover is rotatably connected to the rotating shaft seat of the carrier tank via a rotating shaft bracket.

[0014] In the above process, the top cover can be flipped open by rotating the pivot bracket and pivot seat.

[0015] In one specific implementation, the top of the top cover is provided with a feeding port with a sealing cover and a pressure relief port.

[0016] In the above process, the feed inlet provides a channel for adding feed, and the pressure relief port is used to balance the air pressure inside the bearing tank to ensure the safety of equipment operation.

[0017] In one specific implementation, the top cover is provided with a high-pressure airflow interface, wherein a conduit extending to the bottom of the top cover is installed at the bottom of the high-pressure airflow interface, and a diversion air pipe is installed on the surface of the conduit, wherein nozzles for spraying high-pressure airflow are distributed at the bottom of the diversion air pipe.

[0018] In the above process, high-pressure airflow is injected into the carrying tank through the cooperation of high-pressure airflow interface, conduit, split air pipe and nozzle. This can break up feed clumps, clean up residual feed on the tank wall, and at the same time enhance the feed turning effect and improve the mixing uniformity.

[0019] In one specific implementation, the bottom of the carrying tank is fixedly equipped with support legs with casters and a discharge port.

[0020] In the above implementation process, by setting outriggers with casters, the equipment can be supported and moved flexibly through the casters to adapt to different working scenarios.

[0021] In one specific implementation, the outer surface of the carrier tank is provided with an outer shell, wherein an interlayer is provided between the outer shell and the carrier tank, a guide plate is installed in the interlayer, and an inlet port and an outlet port are installed on the outer shell surface at the beginning and end of the guide plate.

[0022] In the above process, hot and cold media can be introduced into the interlayer through the guide plate, inlet port and outlet port to regulate the temperature of the feed in the carrying tank and expand the applicability of the equipment.

[0023] In one specific implementation, the connecting seat has disassembly and assembly ports on both sides to facilitate the user's disassembly and assembly of the mixing rack.

[0024] In the above implementation process, disassembly and assembly ports are opened on both sides of the connecting seat to provide operating space for disassembly and assembly of the mixing rack, making it convenient for users to operate the limit bolts, simplifying the disassembly and installation process of the mixing rack, and improving maintenance efficiency.

[0025] Compared with existing technologies, the beneficial effects of this application are as follows: By adopting a detachable mixing frame design and using a quick-connect structure between the limiting bolt and the mounting housing, the corresponding blades can be flexibly replaced according to the feed type, solving the problem of insufficient adaptability caused by fixed blades in traditional mixers. Simultaneously, the high-pressure airflow system sprays air from multiple angles, which not only breaks up material clumps but also increases the frequency of material agitation within the tank. Combined with the high-speed rotation of the mixing frame, this effectively ensures that feeds with different characteristics can be uniformly mixed, meeting the feed quality requirements of different livestock and poultry growth stages.

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] Please see Figure 1-8 This application provides a livestock feed mixer, including a carrying tank 1 for carrying feed and a top cover 2 on top of it. The bottom of the carrying tank 1 has three support legs 13 with casters evenly distributed, which are equipped with a brake device. They are flexible and easy to push, and can be locked in place after braking. A discharge port 14 is provided at the center of the bottom of the carrying tank 1. The discharge port 14 is equipped with a manual butterfly valve. The discharge speed can be precisely controlled by rotating the handle. When closed, the silicone sealing ring ensures a leak-free seal.

[0038] The top cover 2 is symmetrically provided with a rotating shaft frame 25 and a locking block 24 on opposite sides. The top edge of the carrying tank 1 is provided with a rotating shaft seat 11 that cooperates with the rotating shaft frame 25 and a buckle 12 that is adapted to the locking block 24. The rotating shaft frame 25 and the rotating shaft seat 11 are rotatably connected by a pin. The buckle 12 is a spring-loaded quick buckle. Pressing the buckle handle will lock it tightly with the locking block 24. When opening, the buckle handle can be easily pulled to unlock it, realizing the quick opening and closing and stable sealing of the top cover 2.

[0039] The top of the top cover 2 is provided with a feeding port 21 with a sealing cover plate. The inner side of the sealing cover plate is inlaid with a silicone sealing ring to effectively prevent dust from leaking out during mixing. A pressure relief port is provided next to the feeding port 21 to balance the air pressure in the carrying tank 1.

[0040] The top rear end of the top cover 2 is provided with a connecting seat 22 for connecting the drive component. The connecting seat 22 has symmetrical disassembly and assembly ports 23 on both sides, providing ample operating space for disassembly and assembly of the mixing rack 33, making it convenient for users to quickly install and remove the limit bolts 35, and simplifying the daily maintenance, cleaning or replacement process of the mixing rack 33.

[0041] A drive motor 3 is installed above the connecting seat 22. A circular connecting plate 31 is provided at the bottom of the drive motor 3. The connecting plate 31 is tightly bolted to the top surface of the connecting seat 22. The output end of the drive motor 3 extends through the connecting plate 31 into the interior of the connecting seat 22. An installation sleeve 32 is fixed at the end of the output shaft. The open end extends vertically to the inner top of the top cover 2 to ensure precise docking with the stirring rack 33.

[0042] The bottom of the top cover 2 is equipped with a stirring frame 33 that extends into the interior of the bearing tank 1. The stirring frame 33 consists of a main rod and multiple layers of stirring blades. A vertical insertion rod 34 is provided on the top of the stirring frame 33, which can be inserted into the mounting sleeve 32. The insertion rod 34 and the mounting sleeve 32 are provided with coaxial connection through holes. A limit bolt 35 is inserted into the through hole. The end of the limit bolt 35 is equipped with an anti-loosening nut to ensure that the stirring frame 33 is firmly connected and to prevent it from coming loose or shaking during high-speed stirring.

[0043] The front end of the top cover 2 is provided with a high-pressure airflow interface 4. The interface adopts a quick-plug structure and is equipped with a dust cap for easy and quick connection to the air source. The bottom of the high-pressure airflow interface 4 is vertically installed with a conduit 41 extending to the bottom of the top cover 2. A diversion air pipe 42 is installed on the surface of the conduit 41. Multiple nozzles 43 are distributed at the bottom of the diversion air pipe 42, which can spray high-pressure airflow into different heights and areas inside the carrying tank 1. This can effectively break up feed clumps, clean residual feed on the tank wall, and increase the frequency of feed turning and improve the mixing uniformity.

[0044] The outer surface of the carrying tank 1 is fitted with an outer shell 5. The outer shell 5 is made of cold-rolled steel plate, which is bent and then powder-coated, providing good corrosion resistance. An annular sandwich is formed between the outer shell 5 and the carrying tank 1. A spiral guide plate 53 is welded inside the sandwich, which fits tightly against the tank wall and guides the medium inside the sandwich to flow along a spiral path, ensuring uniform heat exchange. An inlet port 51 and an outlet port 52 are respectively installed at the beginning and end of the guide plate 53 on the surface of the outer shell 5. By introducing hot water or cold air into the sandwich, the feed inside the carrying tank 1 can be heated or cooled, meeting the temperature requirements when mixing different feeds and expanding the applicability of the equipment.

[0045] The working principle of this livestock feed mixer is as follows: The equipment is moved to the working position and braked and locked using the casters on the support legs 13. After adding feed through the feed inlet 21 of the top cover 2, the top cover 2 is locked in place using the buckle 12 and the locking block 24. The drive motor 3 is fixed to the connecting seat 22 via the connecting plate 31. Its output end is connected to the rod 34 of the mixing frame 33 via the mounting sleeve 32 and the limiting bolt 35, driving the mixing frame 33 to rotate at high speed within the carrying tank 1 to mix the feed. During mixing, the high-pressure airflow interface 4 is connected to the air source, and high-pressure airflow is sprayed from the nozzle 43 through the conduit 41 and the split air pipe 42 to break up clumps and clean residue from the tank wall. If temperature control is required, the medium is introduced into the interlayer between the outer shell 5 and the carrying tank 1 through the inlet interface 51, circulated through the spiral guide plate 53, and discharged from the outlet interface 52 to achieve temperature regulation. The pressure relief port balances the air pressure inside the tank. After mixing, the butterfly valve of the discharge port 14 is opened to discharge the feed, which can be accessed through the disassembly port 23. The mixing rack 33 is easy to disassemble and assemble. When dealing with different materials, the mixing rack 33 with different blade shapes can be replaced. Propeller blades are used for granular materials, toothed blades are used for fibrous materials, and disc blades are used for high-moisture materials. When replacing, locate the limiting bolt 35 at the connection between the top insertion rod 34 of the mixing rack 33 and the mounting sleeve 32 through the disassembly ports 23 on both sides of the connecting seat 22. Use a tool to unscrew the anti-loosening nut at the end of the limiting bolt 35, pull out the limiting bolt 35, and separate the insertion rod 34 from the mounting sleeve 32. Hold the main rod of the mixing rack 33 and vertically lift the old mixing rack 33 out of the carrier tank 1 and place it in the designated area. Select the new mixing rack 33 that is suitable for the feed type, align the top insertion rod 34 with the opening end of the mounting sleeve 32, and insert it vertically to the bottom. Observe through the disassembly port 23 to ensure that the insertion rod 34 and the connecting through hole of the mounting sleeve 32 are coaxially aligned. Then insert the limiting bolt 35 and tighten the anti-loosening nut to complete the replacement operation.

[0046] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
