Specific embodiments

[0031] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0032] Please refer to Figure 1-10The utility model provides a technical solution: a biological fermentation feed fermentation moisture control device, including a base 1, a material making bin 2 is arranged on the top of the base 1, the interior of the material making bin 2 is arranged to be hollow, a power mechanism 4 and a conveying mechanism 3 are arranged on the top of the base 1, the power mechanism 4 and the conveying mechanism 3 are the existing structures in the existing patent: CN214710261U, and no further details are given here. A rotating rod 8 is rotatably connected to the inner wall of the bottom of the material making bin 2, and a flat mold 7 is fixedly sleeved on the outer surface of the other end of the rotating rod 8, and the outer surface of the flat mold 7 contacts the inner wall of the material making bin 2, a fixing rod 6 is arranged on the top of the flat mold 7, and the right end of the fixing rod 6 is fixedly connected to the inner wall of the material making bin 2, the interior of the fixing rod 6 is arranged to be hollow, and a pressing wheel 5 is rotatably sleeved on the outer surface of the fixing rod 6, the interior of the pressing wheel 5 is arranged to be hollow, and the outer surface of the pressing wheel 5 is arranged There are multiple grooves 22, and the two opposite inner walls of the grooves 22 are set to be inclined. The multiple grooves 22 are arranged in a circular array. A moving mechanism is arranged inside the fixed rod 6. A cam 11 is arranged inside the pressing wheel 5. The cam 11 is movably sleeved on the outside of the inner wall of the pressing wheel 5 close to the fixed rod 6. The shape of the cam 11 is truncated cone, and the left surface of the cam 11 is smaller than the right surface. A plurality of sliding rods 12 are arranged on the right side of the cam 11. The plurality of sliding rods 12 are arranged in a circular array, and the end of the sliding rod 12 away from the cam 11 slides through the inside of the pressing wheel 5 and extends into the groove 22. The end of the sliding rod 12 close to the cam 11 is fixedly connected with a semicircular block 17, and a spring 13 is fixedly connected between the semicircular block 17 and the inner wall of the pressing wheel 5. The spring 13 is movably sleeved on the outside of the sliding rod 12, and a scraping mechanism is arranged in the groove 22. The aperture and thickness of the material ring die are not only the main factors affecting the production capacity of the pellet mill, but also affect the moisture content of the pellet feed product. For dies with small apertures, the particle diameter is small, so the cooling air volume of the cooler can easily penetrate the feed particles. Therefore, more moisture is taken away during cooling, and the moisture content of the feed product will be low. On the contrary, the ring die with a large aperture has a larger particle diameter, and the cold air is not easy to penetrate the particles. Less moisture is taken away during cooling, and the moisture content of the feed product will increase. Therefore, before the material making work begins, the moisture content of the fermented feed after material making can be controlled by replacing the appropriate flat die 7. During the material making work, when it is necessary to clean the fermented feed in the groove 22 on the pressing wheel 5, the moving mechanism in the fixed rod 6 is operated, and the moving mechanism drives the cam 11 to move in the direction of the semicircular block 17. When the outer surface of the cam 11 contacts the semicircular block 17, the cam 11 pushes the semicircular block 17 to drive the sliding rod 12 to slide out of the pressing wheel 5 during the movement, and the spring 13 is forced to contract. When the sliding rod 12 slides out of the pressing wheel 5, it drives the scraping mechanism to scrape the fermented feed in the groove 22, thereby ensuring the reasonable utilization rate of the raw materials in the material making work and reducing the production cost as much as possible. In this way, when the fermented feed raw materials are being made, the fermented feed raw materials trapped in the groove 22 can be cleaned to avoid wasting the fermented feed raw materials.

[0033] Furthermore, the moving mechanism includes a cylinder 14 disposed inside the fixed rod 6. A sleeve rod 16 is fixedly sleeved on the output end of the cylinder 14. Two semi-circular grooves 19 are formed on the outer surface of the fixed rod 6. The two semi-circular grooves 19 are respectively disposed on the upper and lower sides of the fixed rod 6 and are respectively parallel to the two sides of the sleeve rod 16. The opposite sides of the sleeve rod 16 respectively extend out of the semi-circular grooves 19 on the same side. The extended sides of the sleeve rod 16 are fixedly connected to the surface of the cam 11 close to the fixed rod 6.

[0034] Furthermore, a circular groove 18 is formed on the inner wall of the pressing wheel 5 close to the fixed rod 6. The circular groove 18 and the semi-circular groove 19 communicate the inside of the fixed rod 6 with the inside of the pressing wheel 5. When the cylinder 14 operates, the output end of the cylinder 14 moves the sleeve rod 16 towards the main body of the cylinder 14, and the upper and lower sides of the sleeve rod 16 synchronously pull the cam 11 towards the main body of the cylinder 14, so that the outer surface of the cam 11 contacts the semi-circular block 17.

[0035] Furthermore, the scraping mechanism includes a U-shaped box 10 disposed in the groove 22. The two vertical rods of the U-shaped box 10 slidably penetrate into the inside of the pressing wheel 5. The bottom surface of the cross bar of the U-shaped box 10 is fixedly connected to the penetrated end of the sliding rod 12, and the bottom surface of the cross bar of the U-shaped box 10 contacts and fits with the bottom inner wall of the groove 22. When the sliding rod 12 slides outwards from the pressing wheel 5, it drives the U-shaped box 10 to move synchronously.

[0036] Furthermore, a limiting block 15 is fixedly connected to one side of the U-shaped box 10 penetrating into the pressing wheel 5. The diameter of the limiting block 15 is larger than the diameter of the vertical rod of the U-shaped box 10. When the U-shaped box 10 moves to a suitable position, the surface of the limiting block 15 away from the fixed rod 6 contacts the inner wall of the pressing wheel 5, so that the vertical rod of the U-shaped box 10 will not completely slide out of the inside of the pressing wheel 5.

[0037] Furthermore, the inside of the U-shaped box 10 is hollow. A second U-shaped frame 20 is disposed inside the U-shaped box 10. The surfaces of the second U-shaped frame 20 close to the inner wall of the U-shaped box 10 are all fixedly connected to the inner wall of the U-shaped box 10. Two U-shaped frames 9 are disposed inside the U-shaped box 10. The two U-shaped frames 9 are respectively disposed outside the opposite sides of the second U-shaped frame 20. A plurality of second springs 21 are fixedly connected between the cross bars and vertical rods of the U-shaped frame 9 and the second U-shaped frame 20.

[0038] Furthermore, the cross section of the U-shaped frame 9 is a right trapezoid, and the inclined surface of the right trapezoid of the U-shaped frame 9 matches the inclined surface of the groove 22.

[0039] Furthermore, the right-angled trapezoidal inclined surface on one side of the mold frame 9 away from the second mold frame 20 slides through the interior of the mold box 10, and the inclined surface on one side of the mold frame 9 located in the groove 22 contacts and fits with the inclined surface of the groove 22. When the sliding rod 12 slides toward the outside of the pressing wheel 5 and drives the mold box 10 to slide in the groove 22, the second spring 21 pushes the right-angled trapezoidal slope of the mold frame 9 to keep in contact and fit with the slope of the groove 22 during the movement of the mold box 10, so that the top of the cross bar of the mold frame 9 and the top of the mold box 10 scrape the fermented feed in the groove 22, and when the pressing wheel 5 rotates, it falls on the top surface of the flat mold 7. The vertical rod slope of the mold frame 9 is always in fit with the groove 22 and is pushed by the second spring 21 during the movement of the mold box 10. When the pressing wheel 5 rotates, the fermented feed passes through the mold box 10 into the groove of the pressing wheel 5 as much as possible, thereby entering the interior of the pressing wheel 5, so that the interior of the pressing wheel 5 can be kept from communicating with the interior of the material making bin 2, thereby preventing the fermented feed from entering the interior of the pressing wheel 5.

[0040] Working principle: Since the aperture and thickness of the material-making ring die are not only the main factors affecting the production capacity of the granulator, but also affect the moisture content of the pellet feed product. For a die with a small aperture, because its pellet diameter is small, the cooling air volume of the cooler is easily penetrated through the feed pellets, so more moisture is carried away during cooling, and the moisture content of the feed product will be relatively low. On the contrary, for a material-making ring die with a large aperture, its pellet diameter is large, and the cold air is not easily penetrated through the pellets, so less moisture is carried away during cooling, and the moisture content of the feed product will increase. Therefore, before the material-making work starts, the moisture of the fermented feed after material-making can be controlled by replacing the appropriate flat die 7. During the material-making work, when it is necessary to clean the fermented feed in the groove 22 on the pressing wheel 5, the moving mechanism in the fixed rod 6 is made to work. The moving mechanism drives the cam 11 to move towards the semi-circular block 17. When the outer surface of the cam 11 contacts the semi-circular block 17, during the movement of the cam 11, it pushes the semi-circular block 17 to drive the sliding rod 12 to slide out of the pressing wheel 5, and the spring 13 is forced to contract. When the sliding rod 12 slides out of the inside of the pressing wheel 5, it drives the scraping mechanism to scrape the fermented feed in the groove 22, ensuring the reasonable utilization rate of the raw materials during the material-making work and minimizing the production cost. In this way, when making the fermented feed raw materials, the fermented feed raw materials sunken in the groove 22 can be cleaned to avoid waste of the fermented feed raw materials. When the cylinder 14 works, the output end of the cylinder 14 makes the sleeve rod 16 move towards the main body side of the cylinder 14, and the upper and lower sides of the sleeve rod 16 synchronously pull the cam 11 towards the main body side of the cylinder 14, so that the outer surface of the cam 11 contacts the semi-circular block 17. When the sliding rod 12 slides outwards of the pressing wheel 5, it drives the U-shaped box 10 to move synchronously. When the U-shaped box 10 moves to a suitable position, the surface of the limiting block 15 away from the fixed rod 6 contacts the inner wall of the pressing wheel 5, so that the vertical rod of the U-shaped box 10 will not completely slide out of the inside of the pressing wheel 5. When the sliding rod 12 slides outwards of the pressing wheel 5 and drives the U-shaped box 10 to slide in the groove 22, during the movement of the U-shaped box 10, the second spring 21 pushes the right-angled trapezoidal inclined surface of the U-shaped frame 9 to always contact and fit with the inclined surface of the groove 22, so that the top of the cross bar of the U-shaped frame 9 and the top of the U-shaped box 10 scrape the fermented feed in the groove 22, and when the pressing wheel 5 rotates, it falls on the top surface of the flat die 7. And because the inclined surface of the vertical rod of the U-shaped frame 9 always fits with the groove 22 and is pushed by the second spring 21 during the movement of the U-shaped box 10, as the pressing wheel 5 rotates, the fermented feed penetrates into the groove of the pressing wheel 5 through the U-shaped box 10 and then enters the inside of the pressing wheel 5, so that the inside of the pressing wheel 5 can be kept not communicating with the inside of the material-making bin 2, preventing the fermented feed from entering the inside of the pressing wheel 5.

[0041] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
