Description

Technical Field

[0001] This utility model relates to the field of pig feed mixing technology, specifically an automatic mixing device for pig feed. Background Technology

[0002] In large-scale pig farming, scientifically formulated complete feed is key to ensuring healthy pig growth and improving farming efficiency. Feed typically consists of corn, soybean meal, wheat bran, premix, vitamins, and liquid additives (such as water, syrup, and acidifiers) mixed in specific proportions. Currently, small and medium-sized farms mostly use manual mixing or simple mixers for this purpose.

[0003] Most current mixers are unidirectional rotary mixers, which make it difficult to form an effective material circulation and are prone to local clumping, stratification or sticking to the wall. At the same time, the feed is very easy to adhere to the cylinder wall and mixing blades after mixing. If it is not cleaned in time and thoroughly, it is easy to breed bacteria and mold. Moreover, the scraper is not adjustable or detachable, and manual cleaning is time-consuming, labor-intensive and ineffective. Therefore, we propose an automatic mixing device for pig feed.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1-5 As shown, this utility model discloses an automatic mixing device for pig feed, including a mixing drum 1. A support frame 2 is fixedly installed at the bottom of the mixing drum 1. A top cover 3 is detachably installed on the top of the mixing drum 1. A protective box 4 is fixedly installed on the top of the top cover 3. A rotating sleeve 5 is rotatably connected inside the mixing drum 1. Two fixed rods 6 are symmetrically connected to the outer periphery of both sides of the rotating sleeve 5. Sliding rods 7 are slidably connected to the inner side of the outer end of each of the four fixed rods 6. Guide rails 8 are fixedly connected to the outer side of each of the four sliding rods 7. Scrapers 9 are provided on the outer side of each of the two guide rails 8.

[0025] The inner side of the scraper 9 is provided with a sliding groove 10, and the inner surface of the sliding groove 10 is slidably connected to the guide rail 8. It can be slidably disassembled along the axial direction of the guide rail 8. The bottom of the guide rail 8 is fixedly connected with a limit block 11, and the top of the limit block 11 is in contact with the bottom of the scraper 9. The cooperation between the sliding groove 10 and the limit block 11 ensures the stable operation of the scraper 9 and supports quick disassembly, cleaning or replacement after shutdown, thus improving the convenience of maintenance.

[0026] The protective box 4 has a geared motor 12 fixedly installed on one side inside. The output end of the geared motor 12 is connected to a helical gear 13 via a coupling. The bottom of the outer side of the helical gear 13 is meshed with a helical gear 14, and the bottom of the helical gear 14 is fixedly connected to the top of the rotating sleeve 5. The geared motor 12 drives the rotating sleeve 5 to rotate as a whole through the helical gear transmission system, providing stable power for the main stirring.

[0027] Among them, the top of the helical gear 14 is fixedly connected to the fixed column 15, and the top of the fixed column 15 is fixedly installed with the micro motor 16. The output end of the micro motor 16 is connected to the drive shaft 17 through the coupling. Two bevel gears 20 are fixedly connected to the lower outer circumference of the drive shaft 17. The micro motor 16 is independently installed above the main drive shaft to provide a dedicated power source for the radial adjustment mechanism of the scraper 9, realizing functional decoupling control.

[0028] Among them, the four fixed rods 6 are rotatably connected to threaded rods 18, and one end of the threaded rod 18 is connected to the internal thread of the slide rod 7. The other end of the four threaded rods 18 is fixedly connected to the outer periphery of bevel gears 19, and the bevel gears 19 are meshed with the bevel gears 20. The threaded rods 18 and the bevel gears 19 form a telescopic transmission chain, which converts the rotation of the micro motor 18 into the linear motion of the slide rod 7, thereby adjusting the wall-adhering pressure of the scraper 9.

[0029] The bottom of the mixing drum 1 is funnel-shaped, and the bottom of the rotating sleeve 5 is fixedly connected to a spiral feeding shaft 21, which extends to the bottom of the mixing drum 1. Spiral feeding blades 22 are fixedly connected to the outer periphery of the spiral feeding shaft 21. Through the spiral feeding structure, the material is formed to circulate up and down during the mixing process, which significantly improves the mixing uniformity and prevents material accumulation at the bottom.

[0030] The mixing drum 1 is fixedly connected to the bottom center end of the discharge pipe 23, and a control valve 24 is set on the lower outer periphery of the discharge pipe 23. Universal wheels 25 are fixedly installed on all four bottom sides of the support frame 2. The top of the top cover 3 is fixedly connected to the feed pipe 26, and a sealing cover is set on the top of the feed pipe 26. An observation window 27 is fixedly connected to the outside of the mixing drum 1. By integrating discharge control, universal wheels, sealed feed and visual observation window, the requirements of operation safety, flexibility and process monitoring are taken into account.

[0031] Working Principle: In operation, first open the sealing cap at the top of the feed pipe 26, and add various pig feed ingredients (such as corn flour, soybean meal, and premix) sequentially into the mixing drum 1, then tighten the sealing cap. Start the reduction motor 12, which, through the meshing transmission of helical gear 13 and helical gear 2 14, drives the rotating sleeve 5 to rotate as a whole. The fixed rod 6, sliding rod 7, and scraper 9 on it revolve accordingly, performing preliminary mixing of the feed. Simultaneously, start the micro motor 16, whose power is transmitted through the transmission shaft 17 and bevel gear 20 to the bevel gear 19, driving the four threaded rods 18 to rotate synchronously. This causes the sliding rod 7 to extend radially outward along the fixed rod 6, pushing the scraper 9 to adhere tightly to the inner wall of the mixing drum 1. During rotation, the scraper 9 continuously scrapes away wet or sticky components adhering to the drum wall, preventing clumping and residue. Meanwhile, the spiral feeding shaft 21 at the bottom of the rotating sleeve 5 rotates together with the main shaft, and the spiral feeding blades 22 push the feed that has settled to the bottom of the funnel upward, forming a three-dimensional circulating flow field of "bottom feeding upward and top falling", which significantly improves the mixing uniformity and shortens the mixing time. After mixing is completed, the control valve 24 is opened, and the finished feed is automatically discharged through the discharge pipe 23. The operator can monitor the mixing status throughout the process through the observation window 27. After the equipment is stopped, the geared motor 12 can be started to drive the rotating sleeve 5 to rotate at a low speed. At the same time, clean water or cleaning solution is injected from the feed pipe 2. The scouring effect generated by the rotation is used to quickly wash the inner wall and internal components of the mixing drum 1. The scraper 9 continuously scrapes off the wet material or sticky components attached to the drum wall to prevent residue. After cleaning is completed, the top cover 3 is removed. The operator can lift the scraper 9 upward, so that the scraper 9 slides along the guide rail 8 axially through the inner groove 10, thereby sliding the scraper 9 out of the guide rail 8 as a whole, realizing quick disassembly. The removed scraper 9 can be thoroughly cleaned or replaced individually, effectively preventing feed residue, mold, or cross-contamination, significantly improving equipment maintenance efficiency and hygiene, and facilitating cleaning and maintenance. It is highly efficient in mixing feed, leaves little residue, and is easy to clean, making it particularly suitable for daily feed preparation in large-scale farms.
