Description

Technical Field

[0001] This utility model relates to the field of feed compression devices for livestock breeding, and in particular to an automated feed compression device for livestock breeding with adjustable feeding amount. Background Technology

[0002] The adjustable feed compression device is a feed processing equipment with an integrated intelligent control system. It can not only compress raw materials into high-density pellets or blocks, but also dynamically adjust the feed amount according to the animal species, growth stage or environmental needs to achieve precise nutrition supply. Its core breakthrough lies in the integrated design of "compression-feeding", which is suitable for refined farming scenarios.

[0003] Existing technology uses a screw propeller to feed compressed feed, and then uses a servo motor to precisely adjust the feed amount. However, when quantitatively feeding compressed pelleted feed, the pellets are subjected to shear force when they come into contact with the edge of the screw blades, exceeding their yield strength, which leads to breakage of the pellets. This not only generates dust but also causes the loss of internal nutrients. Existing technology uses a double-screw propulsion system to reduce pellet breakage, but the existing double-screw structure is difficult to precisely control the speed difference. When the speed difference reaches a certain value, the pellets are subjected to bidirectional shear force, increasing the breakage rate of the pellets and causing inconvenience in daily use.

[0004] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem of feed compression devices in livestock farming, this utility model provides an automated feed compression device for livestock farming with adjustable feeding volume.

[0006] The present invention provides an automated feed compression device for livestock farming with adjustable feeding volume, which adopts the following technical solution:

[0007] An automated feed compression device for livestock farming with adjustable feeding amount includes a compression component and a feeding component, as well as a feeding component disposed on the side of the compression component away from the feeding component. It also includes a feeding component with a biomimetic asymmetric spiral structure fixedly connected to the bottom end of the feeding component. The feeding component is assembled to transport the compressed pellet feed into the feeding component through the feeding component. It works in conjunction with a biomimetic asymmetric pusher. The differential pitch of the inner and outer spirals allows the pellets to undergo multiple adjustments during the propulsion process, reducing their collision kinetic energy. The differential design of the spiral blade inclination angle converts the unidirectional thrust into multidirectional component force, offsetting the shearing effect caused by the speed difference, which can effectively reduce the breakage rate of the pellet feed.

[0008] Furthermore, the feeding component includes a collection box fixedly connected to the feeding component, a feeding port opened at the connection between the collection box and the feeding component, a feeding port opened on the bottom side of the collection box away from the feeding port, and a pusher component rotatably installed inside the collection box.

[0009] Furthermore, the pusher consists of two asymmetrically arranged sets, including a first helical blade with a gradually varying pitch and a second helical blade with a fixed pitch.

[0010] Furthermore, the first helical blade has an external thread, the second helical blade has an external thread, and the blade inclination angle of the first helical blade is greater than that of the second helical blade. The helical diameter of the first helical blade is greater than that of the second helical blade, and the bottom ends of the first and second helical blades are on the same plane.

[0011] Furthermore, the first helical blade is made of silicon nitride ceramic material to bear steady-state loads, while the second helical blade is made of carbon fiber reinforced composite material, which can absorb high-frequency vibration energy.

[0012] In summary, this utility model has the following beneficial technical effects:

[0013] The present invention discloses an automated feed compression device for livestock farming with adjustable feeding amount. Through the biomimetic asymmetrical pusher component, and the differentiated pitch of the inner and outer spirals of the first and second spiral blades, the pellets undergo multiple adjustments during the propulsion process, reducing their collision kinetic energy. Furthermore, the differentiated design of the spiral blade inclination angle converts unidirectional thrust into multidirectional thrust, offsetting the shearing effect caused by the speed difference, and effectively reducing the breakage rate of pellet feed.

[0020] The following is in conjunction with the appendix Figure 1 —5. This utility model will be described in further detail.

[0021] This utility model provides an automated feed compression device for livestock farming with adjustable feeding amount, including a mounting frame 1, a compression component 2, and a feeding component 3, as well as a feeding component 4 disposed on the side of the compression component 2 away from the feeding component 3. It also includes a feeding component 5 with a biomimetic asymmetric spiral structure fixedly connected to the bottom end of the feeding component 4. It is assembled to transport the compressed pellet feed into the feeding component 5 through the feeding component 4, and cooperates with the biomimetic asymmetric pusher 55. Through the differential pitch setting of the inner and outer spirals, the pellet group undergoes multiple adjustments during the propulsion process, reducing its collision kinetic energy. Through the differential design of the spiral blade tilt angle, the unidirectional thrust is converted into multi-directional component force, which offsets the shearing effect caused by the speed difference and effectively reduces the breakage rate of the pellet feed.

[0022] Specifically, the mounting frame 1 serves as a support for mounting the compression assembly 2 and the feeding assembly 5. The compression assembly 2, driven by a hydraulic servo system, uses a pressure roller to cooperate with a mold to compress raw materials into high-density pellets or block feed according to the set parameters. The feeding assembly 3 can be a conveyor belt with a closed shell or other enclosed conveyor that can be used to transport feed. It is used to transport the raw materials to the compression assembly 2 for compression processing. The discharging assembly 4 can be a closed hopper or other enclosed discharging device that can transport feed. It is used to transport the compressed high-density pellet feed to the feeding assembly 5. The feeding assembly 5 feeds the compressed pellet material in a quantitative manner. The feeding assembly 3 is located on the upper side of one end of the compression assembly 2, and the discharging assembly 4 is located on the lower side of the end of the compression assembly 2 away from the feeding assembly 3. The above structure is the prior art well known to those skilled in the art. The relevant structure or type is given in this embodiment and will not be described in detail here.

[0023] In this embodiment, the feeding component 5 includes a collection box 51 fixedly connected to the feeding component 4, a feeding port 52 opened at the connection between the collection box 51 and the feeding component 4, a feeding port 53 opened on the bottom side of the collection box 51 away from the feeding port 52, a pusher 55 rotatably installed inside the collection box 51, and a servo motor 54 provided on one side of the collection box 51.

[0024] Specifically, the collection bin 51 is used to install the feeding component 5 and collects the compressed pelleted feed through its internal cavity. The feeding component 4 conveys the compressed feed into the collection bin 51 through the feeding port 52. The feeding port 53 is used to convey the material to the feeding area. The pusher 55 conveys the pelleted feed from the feeding port 52 to the feeding port 53, and works with the servo motor 54 to quantitatively adjust the feeding amount.

[0025] In this embodiment, the pusher 55 consists of two asymmetrically arranged sets, including a first helical blade 551 with a gradually varying pitch and a second helical blade 552 with a fixed pitch. The first helical blade 551 has an external thread, the second helical blade 552 has an external thread, and the blade inclination angle of the first helical blade 551 is greater than that of the second helical blade 552. The helical diameter of the first helical blade 551 is greater than that of the second helical blade 552, and the bottom ends of the first helical blade 551 and the second helical blade 552 are on the same plane.

[0026] Specifically, the first helical blade 551 is made of silicon nitride ceramic material to bear steady-state loads, and the second helical blade 552 is made of carbon fiber reinforced composite material to absorb high-frequency vibration energy. The first helical blade 551 dynamically adapts to the rheological properties of the particles to reduce backflow friction, and the second helical blade 552 pre-disperses the particles to reduce initial collision energy.

[0027] Working principle: First, the feed raw materials are conveyed to the compression component 2 through the feeding component 3 for compression processing. Then, the compressed granular feed is conveyed to the discharging component 4 for feeding. Then, the servo motor 54 is started and drives the pusher 55 to rotate. The granular feed is conveyed into the collection box 51 through the feeding port 52 and is conveyed by the asymmetrically set first spiral blade 551 and second spiral blade 552. The servo motor 54 is used to adjust the feeding amount of granular feed. Through the differential pitch setting of the inner and outer spirals of the first spiral blade 551 and the second spiral blade 552, the granular group undergoes multiple adjustments during the propulsion process, reducing its collision kinetic energy. The differential design of the spiral blade tilt angle converts the unidirectional thrust into multi-directional component force, offsetting the shearing effect caused by the speed difference, effectively reducing the breakage rate of granular feed. Then, the granular feed is discharged through the discharging port 53, and the workers can feed the livestock.
