Description

Technical Field

[0001] The utility model relates to the technical field of feed preparation, in particular to a conical diffusion feeding device. Background Art

[0002] At present, the feeding methods of pig farms are mainly divided into dry feed feeding and liquid feed feeding; liquid feed feeding requires adding a certain amount of water in the mixing tank in advance, and then adding a certain amount of dry feed. After being fully mixed under the action of the stirring mechanism, the liquid feed is pumped through a pipeline to each feed trough in the pig house for pigs to eat. Among them, dry feed is usually stored in a hopper, which is installed on the top of the mixing tank, and a discharge port is set at the bottom of the hopper, and a plug switch is installed at the discharge port; when liquid feed needs to be prepared, the plug switch is turned on, and the dry feed enters the mixing tank from the discharge port and is mixed evenly by the stirring mechanism in the mixing tank.

[0003] However, when the above-mentioned plug switch is used for feeding, the feed gathers and falls from the discharge port under the action of gravity and is not easy to disperse; especially when the amount of feed is large, the feed that falls into the water does not have time to fully dissolve and mix with the water, and will accumulate in the water just below the feeding point in a short time, thereby increasing the workload of the stirring mechanism; in addition, the accumulated feed cannot be dissolved and mixed with water in a short time, and manual intervention is required for stirring, which not only prolongs the water-feed mixing time, but also increases manual labor. Utility Model Content

[0004] The utility model provides a conical diffusion feeding device, which can solve the technical problems of the existing feeding device that feed is in a clustered state when falling and is not easy to disperse, resulting in increased workload of the stirring mechanism and prolonged mixing time.

[0005] This application provides the following technical solutions:

[0006] A conical diffusion feeding device comprises a hopper, a discharge port is arranged at the bottom of the hopper, a feeding assembly is also arranged in the hopper, the feeding assembly comprises a driving member, a push-pull rod and a guide cone arranged at the bottom of the push-pull rod, the driving member is arranged at the top of the hopper, the power output end of the driving member is connected to the push-pull rod, and is used to drive the push-pull rod to perform lifting movement, the small end of the guide cone is located in the hopper, and the large end passes through the discharge port and extends into the mixing cylinder; when the push-pull rod performs lifting movement, the guide cone is used to close or open the discharge port.

[0007] Beneficial effects:

[0008] 1. Uniform feeding and dispersion: Setting a guide cone at the discharge port helps to evenly spread the dry feed along the cone surface during the feeding process. When the feed enters the mixing tank through the guide cone, the conical structure helps the feed to spread quickly, reducing accumulation, increasing the contact area between feed and water, speeding up the mixing of water and feed, and improving the mixing uniformity.

[0009] 2. Reduce the mixing load: Since the feed is evenly dispersed by the guide cone, it avoids a large amount of feed from being concentrated in one place, reducing the workload of the mixing mechanism. The mixer no longer needs extra work to break up large pieces of accumulated feed, thereby reducing energy consumption and extending the service life of the mixing equipment.

[0010] 3. Automation improves efficiency: Through the linkage between the drive and the push-pull rod, the automatic control of the unloading process is realized. When unloading is required, the drive drives the push-pull rod to move downward, pushing the guide cone downward to open the discharge port. After unloading is completed, the drive drives the push-pull rod upward to retract, and the guide cone moves upward to close the discharge port; reducing manual intervention, reducing manual labor, and improving production efficiency, making the feed preparation process more continuous and efficient. In addition, automated unloading reduces the need for workers to directly contact the feed and the mixing process, improves the working environment, reduces occupational health and safety risks, and improves the sanitary conditions of the operation.

[0011] 4. Reduce mixing time: The uniform and fast feeding process significantly shortens the time required to mix feed and water, improves production rhythm, enables pig farms to complete feed preparation more efficiently, and reduces production costs.

[0012] Furthermore, a compression spring is sleeved on the bottom of the push-pull rod, and an end plate is provided at the end of the small end of the guide cone. The end plate is slidably sleeved on the push-pull rod, and its bottom is connected to the compression spring.

[0013] Beneficial effects: The buffering and adaptive adjustment characteristics of the compression spring make the entire unloading process smoother and more stable, reduce equipment failures caused by impact or vibration, and improve the overall stability and reliability of the system; in addition, when the guide cone closes the discharge port, the pressure of the compression spring can enhance the sealing effect.

[0014] Furthermore, the driving member is any one of a pneumatic cylinder, a hydraulic cylinder, and an electric push rod.

[0015] Beneficial effects: When using, you can choose according to the amount of material being cut, cost, control accuracy, etc.

[0016] Furthermore, the top of the hopper is opened, and the driving member is arranged at the middle position of the top of the hopper through a fixing plate, and the fixing plate is detachably connected to the hopper.

[0017] Beneficial effects:

[0018] 1. Optimize space utilization and stability: Placing the drive part in the middle of the top of the hopper can ensure that the push-pull rod moves up and down in the direction of the center line of the hopper, which can more evenly distribute the thrust of the push-pull rod, avoid eccentric loading, and improve the stability and balance of the entire device; at the same time, the layout of the middle position helps to reduce the occupation of the space around the hopper, making the overall equipment more compact and easy to install and operate in a limited space.

[0019] 2. Convenience of maintenance and overhaul: The detachable connection design between the fixed plate and the hopper greatly simplifies the maintenance and overhaul process of the equipment; when the drive parts need to be inspected, repaired or replaced, the operator can quickly remove the fixed plate and directly access the drive parts without large-scale disassembly of the entire hopper structure, which greatly shortens the maintenance time and reduces the maintenance cost.

[0020] Furthermore, the fixing plate is a "J"-shaped structure, including a top plate, side plates, and a bottom plate. A plurality of mounting holes are provided on the bottom plate, and the bottom plate is used to be connected to the top of the hopper.

[0021] Beneficial effects: The "J"-shaped structure forms a more stable frame through the combination of the top plate, side plates and bottom plate, providing stronger support for the drive parts; this structural design allows the side plates to be used as gripping points or support points for operating and maintenance personnel, facilitating operations when maintaining and repairing the drive parts, thereby improving work efficiency and safety.

[0022] Furthermore, a cover plate is provided on the top of the hopper, and the cover plates are located on both sides of the fixed plate for closing the opening at the top of the hopper, and one side of the cover plate close to the fixed plate is arranged on the bottom plate of the fixed plate.

[0023] Beneficial effects: The cover is used to cover the top of the hopper to prevent dust and foreign matter from entering, ensuring the cleanliness of the feed and reducing the risk of contamination.

[0024] Furthermore, a mounting plate is provided at the bottom of the hopper, a plurality of screw holes are provided on the mounting plate, and the mounting plate is connected to the top of the mixing cylinder.

[0025] Beneficial effect: It is convenient to firmly install the hopper on the top of the mixing tank.

[0026] Furthermore, a control valve for controlling the extension and retraction of the driving member is also arranged on the fixed plate, so as to facilitate the realization of automatic control.

[0027] Furthermore, a protective tube is provided at the bottom of the fixing plate, and the power output end of the driving member and the push-pull rod are both located in the protective tube.

[0028] Beneficial effect: The protective tube can play a certain blocking role on the feed in the hopper, preventing the feed from directly contacting and sticking to the power output end of the driving part, affecting the normal lifting function. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1

[0035] like Figure 1-3 As shown, a conical diffusion feeding device includes a hopper 1. The hopper 1 is a conical structure. A discharge port 11 is arranged at the bottom of the hopper 1. The top of the hopper 1 is opened, and a mounting flange 12 extending outward is arranged around the top of the hopper 1. In order to facilitate the installation of the hopper 1 on the mixing cylinder, the present embodiment further provides a mounting plate 2 at the bottom of the hopper 1. A plurality of screw holes 21 are arranged on the mounting plate 2, and the mounting plate 2 is connected to the top of the mixing cylinder by screws. A feed port is arranged at the top of the mixing cylinder, and the discharge port 11 of the hopper 1 corresponds to the feed port of the mixing cylinder.

[0036] like Figure 2 As shown, a material discharge assembly is also provided in the hopper 1, and the material discharge assembly includes a driving member 31, a push-pull rod 32, and a guide cone 33 arranged at the bottom of the push-pull rod 32. The driving member 31 is arranged at the top of the hopper 1, and the power output end of the driving member 31 is connected to the push-pull rod 32, which is used to drive the push-pull rod 32 to move up and down. The small end of the guide cone 33 is located in the hopper 1, and the large end passes through the discharge port 11 and extends into the mixing cylinder; when the push-pull rod 32 moves up and down, the guide cone 33 is used to close or open the discharge port 11.

[0037] Specifically, the driving member 31 is arranged at the middle position of the top of the hopper 1 through the fixing plate 4, and the fixing plate 4 is detachably connected to the hopper 1. More preferably, the fixing plate 4 in this embodiment is a "J"-shaped structure, including a top plate, two side plates and two bottom plates, and a plurality of mounting holes 41 are arranged on the bottom plate, and the bolts pass through the mounting holes 41 on the bottom plate to connect with the mounting flange 12 on the top of the hopper 1. The driving member 31 can be any one of a cylinder, a hydraulic cylinder, and an electric push rod; the present embodiment preferably uses a cylinder, and in order to facilitate the control of the cylinder, a solenoid valve 311 is also arranged on the fixing plate 4, and the solenoid valve 311 is used to control the piston rod of the cylinder to reciprocate.

[0038] like Figure 1 As shown, a cover plate 5 is also provided on the top of the hopper 1, and the cover plate 5 is located on both sides of the fixing plate 4, and is used to close the opening on the top of the hopper 1; in this embodiment, the cover plate 5 is made of HDPE plate, which is easy to open and cut, so as to be easily matched with different hoppers 1. Specifically, the cover plate 5 is cut into a semicircular structure, the edge of the cover plate 5 is connected to the mounting flange 12 on the top of the hopper 1, and the side of the cover plate 5 close to the fixing plate 4 is arranged on the bottom plate of the fixing plate 4 and fixed by bolts.

[0039] like Figure 3 As shown, in this embodiment, a compression spring 6 is also sleeved on the bottom of the push-pull rod 32, and an end plate 331 is provided at the end of the small end of the guide cone 33. The end plate 331 is slidably sleeved on the push-pull rod 32, and its bottom is connected to the compression spring 6; the top of the push-pull rod 32 is connected to the piston rod of the cylinder. In order to prevent the feed from directly contacting the piston rod of the cylinder, a protective tube 7 is also provided at the bottom of the fixed plate 4 in this embodiment, and the piston rod of the cylinder and the upper half of the push-pull rod 32 are both located in the protective tube 7.

[0040] When it is necessary to discharge the feed, the solenoid valve 311 is used to control the cylinder to work, and the piston rod of the cylinder is extended, driving the push-pull rod 32 to move downward to push the guide cone 33 downward. At this time, a gap is generated between the discharge port 11 of the hopper 1 and the guide cone 33, and the discharge port 11 is opened. The feed is dispersed over a wider area along the inclined surface of the guide cone 33 and falls into the mixing tank to be fully dissolved and mixed with water. The problem of feed accumulation when falling from a single point can be solved. When the feed is mixed with water, since the feed has been preliminarily diffused, the stirring mechanism can more efficiently mix it with water, thereby improving the preparation efficiency and quality of the liquid material, and no human intervention in stirring is required.

[0041] When the feeding is finished or there is no need to prepare liquid material, the solenoid valve 311 controls the piston rod of the cylinder to retract, thereby driving the push-pull rod 32 to move upward, and the guide cone 33 seals the discharge port 11 of the hopper 1, and the discharge port 11 is closed; at this time, no feed will fall, and it can also prevent the water vapor in the mixing cylinder below the hopper 1 from entering the hopper 1 through the discharge port 11 and making the feed moist.

[0042] In summary, the feeding device provided in the present application can disperse dry feed, reduce accumulation, increase the contact area between feed and water, speed up the mixing of water and feed, and improve the mixing uniformity; and because the feed is evenly dispersed by the guide cone, a large amount of feed is avoided from being concentrated in one place, the workload of the stirring mechanism is reduced, and the mixer no longer requires extra work to break up large pieces of accumulated feed, thereby reducing energy consumption and extending the service life of the stirring equipment; finally, the driving member is used to drive the push-pull rod to move up and down, thereby opening or closing the discharge port, reducing manual intervention, reducing manual labor, and improving production efficiency, making the feed preparation process more continuous and efficient.
