Description

Technical Field

[0001] The present invention relates to the technical field of ecological pig breeding, and specifically relates to an ecological pig breeding method for improving meat quality. Background Art

[0002] Ecological pig breeding refers to breeding pigs in a natural environment with natural feeding and free movement to produce pork.

[0003] The specific methods are as follows:

[0004] 1. Free-range method: Ecological pigs are bred in a free-range manner, allowing pigs to live in natural environments such as forests and grasslands. This method can provide sufficient exercise and space for the free development of pigs, making the ecological pigs healthier.

[0005] 2. Forage method: In ecological pig breeding, pigs eat not only feed but also plants such as grass and rhizomes. Therefore, forage is also one of the important breeding methods. Farmers need to provide fresh and clean forage for pigs to avoid pigs eating moldy or rotten forage, which may affect the health of pigs.

[0006] 3. Free drinking water: Ecological pig breeding requires providing clean drinking water for pigs, and pigs should be able to drink water freely at any time to ensure the smooth excretion of metabolic products in the ecological pigs.

[0007] Currently, when using the ecological pig breeding method, it is often unable to ensure the exercise of ecological pigs and guarantee the daily exercise time of ecological pigs. At the same time, it is not convenient to massage ecological pigs, thus improving the meat quality and taste of ecological pigs. Therefore, improvements are needed for the above problems. Summary of the Invention

[0008] In view of the problems in the prior art, the present invention provides an ecological pig breeding method for improving meat quality.

The upper end of the movable frame 17 is fixedly connected to the limit frame 16. A motor is installed on the limit frame 16 to control the rotational connection of the massage structure 13. The limit frame 16 is also fixedly connected to the limit rod 15. The first lead screw 14 rotates on the limit frame 16. The first lead screw 14 is threadedly connected to the massage structure 13, and the massage structure 13 is slidably connected to the limit rod 15. When it is necessary to repair the conveyor belt 32, at this time, the electric control hydraulic telescopic rod 11 can be telescoped and adjusted to drive the support platform 7 and the first docking hinge seat 8 to adjust the height. The front end of the fixed side block 34 is hinged to the fixed bottom block 33. Under the control of the electric control hydraulic telescopic rod 11, the support platform 7 drives the bottom support plate 35 to move, changing the position of the fixed side block 34, so that the fixed side block 34 moves relative to the fixed bottom block 33, changing the inclination of the conveyor belt 32 to facilitate the repair work.

[0048] There are two massage structures 13, which are symmetrically arranged about the limit frame 16. The threads on the first lead screw 14 are arranged symmetrically and reversely, so that the two massage structures 13 move in opposite directions.

Through continuous rotation, the massage sleeve rod 26 contacts the ecological pigs to perform the massage work on the ecological pigs. Moreover, the massage sleeve rod 26 can also rotate on the bearing seat 24 via the rotating control rod 25 to improve comfort.

[0051] The breeding component 12 includes a hydraulic connecting seat 27, a scraper 28, a pressure control seat 29, a first partition 30, a second partition 31, a conveyor belt 32, a fixed bottom block 33, a fixed side block 34, a bottom support plate 35, and a third control motor 36. A conveyor belt 32 is drivenly connected to the third control motor 36. The conveyor belt 32 is limited by a bearing seat 24. The lower end of the fixed side block 34 is fixedly connected to a bottom support plate 35. The ecological pigs are driven into the breeding control structure 1 through the guiding seat 2. At this time, the ecological pigs are on the conveyor belt 32. The third control motor 36 can control the rotation and transmission of the conveyor belt 32, enabling the ecological pigs to move cooperatively and increasing the average daily steps of the ecological pigs. When the conveyor belt 32 is driven, it can guide the feces into the grille drainage seat 4, and after flushing, it is discharged through the drainage pipe 3. At the same time, the pressure control seat 29 can control the hydraulic connecting seat 27 to change the pressure, causing the scraper 28 to extend, so that the scraper 28 contacts the rear end of the conveyor belt 32 to perform the cleaning work of the conveyor belt 32, scraping off the waste on the surface of the conveyor belt 32 for convenient subsequent collection.

[0052] The side end of the fixed side block 34 is relatively movably connected with a fixed bottom block 33. The upper end of the fixed bottom block 33 is fixedly connected with a conduction belt 32.

The first partition 30, the second partition 31, and the fixed bottom block 33 are fixed, which is convenient for the breeding enclosure work of ecological pigs. When the appropriate time arrives, the first control motor 19 at this time can control the second lead screw 18 to rotate, changing the longitudinal position of the movable frame 17. At the same time, the motor controls the first lead screw 14 to rotate, so that the massage structures 13 on both sides move in the reverse direction under the limit sliding of the limit rods 15 and the limit frames 16, enabling the massage structures 13 to contact the ecological pigs and perform the massage work on the ecological pigs.

[0054] The working principle is as follows: When in use, the user drives the ecological pigs into the breeding control structure 1 through the guiding seat 2. At this time, the ecological pigs are on the conduction belt 32. The third control motor 36 can control the conduction belt 32 to rotate and transmit, enabling the ecological pigs to move cooperatively, increasing the average daily steps of the ecological pigs. When the conduction belt 32 is driving, it can guide the feces into the grid drainage seat 4. After flushing, it is discharged through the drainage pipe 3. At the same time, the pressurization control seat 29 can control the hydraulic connection seat 27 to change the pressure, making the scraper 28 extend, so that the scraper 28 contacts the rear end of the conduction belt 32, performing the cleaning work of the conduction belt 32, scraping the waste on the surface of the conduction belt 32, which is convenient for subsequent collection;

[0055] And the first partition 30, the second partition 31, and the fixed bottom block 33 are fixed, which is convenient for the breeding enclosure work of ecological pigs. When the appropriate time arrives, the first control motor 19 at this time can control the second lead screw 18 to rotate, changing the longitudinal position of the movable frame 17. At the same time, the motor controls the first lead screw 14 to rotate, so that the massage structures 13 on both sides move in the reverse direction under the limit sliding of the limit rods 15 and the limit frames 16, enabling the massage structures 13 to contact the ecological pigs and perform the massage work on the ecological pigs;

[0056] At this time, the second control motor 20 controls the rotation ring frame 23 to rotate through the drive rod. The rotation ring frame 23 is connected with a massage sleeve rod 26 through a bearing seat 24 and a rotation control rod 25. Through continuous rotation, the massage sleeve rod 26 contacts the ecological pigs, performing the massage work on the ecological pigs. And the massage sleeve rod 26 can also rotate on the bearing seat 24 through the rotation control rod 25 to improve the comfort level;

[0057] When maintenance of the conveyor belt 32 is required, the electro-hydraulic telescopic rod 11 can be telescopically adjusted at this time, driving the support platform 7 and the first docking hinge seat 8 to adjust the height. The front end of the fixed side block 34 is hinged to the fixed bottom block 33. Under the control of the electro-hydraulic telescopic rod 11, the support platform 7 drives the bottom support plate 35 to move, changing the position of the fixed side block 34, causing the fixed side block 34 and the fixed bottom block 33 to move relative to each other, changing the inclination of the conveyor belt 32, facilitating the maintenance work, and completing the work.
