Description

Technical Field

[0001] This utility model relates to the technical field of feed production and processing equipment, and in particular to an adjustable speed addition device for feed-grade animal fats. Background Technology

[0002] In the feed production process, an appropriate amount of animal fat needs to be added to the basic feed ingredients to increase the feed energy density, improve the palatability and nutritional balance of the feed. The rate and amount of animal fat added directly affect the final quality of the feed and the production efficiency.

[0003] However, in the existing technology, most feed-grade animal fat addition devices adopt a fixed aperture feeding structure or manually adjust valves to control the addition speed. This has the problems of low addition speed adjustment accuracy and high labor intensity of manual operation, making it difficult to adapt to the differentiated requirements of different feed formulations for the amount of fat added. Some adjustable speed devices have defects such as unstable transmission structure and narrow adjustment range. They are prone to fluctuations in addition speed due to changes in the fluidity of fat. Moreover, the overall installation and maintenance of the device is inconvenient, which increases the equipment operation and maintenance costs in the feed production process. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low adjustment accuracy, unstable transmission, narrow adjustment range and inconvenient maintenance of feed-grade animal fat additive devices in the existing technology, and to propose an adjustable speed additive device for feed-grade animal fat.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable speed adding device for feed-grade animal oil, comprising a support frame, wherein a speed adjusting mechanism is detachably installed on the top of the support frame, the speed adjusting mechanism comprising a feeding hopper, a discharge pipe and a sealing block, the discharge pipe being fixedly installed at the bottom of the feeding hopper, the discharge pipe having a conical cavity inside, the sealing block being inserted into the conical cavity, a transmission rod being fixedly connected to the top of the sealing block, a servo motor being provided at the center of the feeding hopper, and a threaded rod being fixedly connected to the output end of the servo motor, the threaded rod being threadedly connected to the transmission rod.

[0006] Preferably, a threaded cavity is provided at the junction of the transmission rod and the threaded rod, and the length of the threaded cavity is more than twice that of the threaded rod.

[0007] Preferably, a support plate is fixedly installed on the top of the hopper, and a limit plate is fixedly installed on the edge of the support plate. The servo motor is connected to the limit plate by bolts.

[0008] Preferably, fixing rods are symmetrically installed on both sides of the support frame, and the ends of the fixing rods are connected to the outer wall of the discharge pipe by bolts.

[0009] Preferably, a connecting base plate is fixedly installed at the bottom of the support frame, and a reinforcing frame is fixedly installed at the top of the support frame.

[0010] Preferably, guide rods are symmetrically installed on both sides of the transmission rod, and the guide rods are slidably connected to the support plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the rotation of the threaded rod is driven by a servo motor. Combined with the linkage structure between the transmission rod and the sealing block, as well as the sliding cooperation between the guide rods symmetrically arranged on both sides of the transmission rod and the support plate, the rotational motion of the threaded rod can be accurately converted into the linear motion of the sealing block in the conical cavity of the discharge pipe. At the same time, the rotation of the transmission rod can be restricted to ensure the smooth movement of the sealing block. This achieves high-precision adjustment of the grease addition speed and effectively solves the problems of low adjustment accuracy and unstable transmission in existing devices.

[0012] 2. In this utility model, the speed regulating mechanism is detachably installed on the top of the support frame, and is connected to the fixed rod and the discharge pipe by bolts. This facilitates the overall disassembly and maintenance or replacement of parts of the speed regulating mechanism in the future, reduces the difficulty of device maintenance, and solves the problems of narrow adjustment range and inconvenient maintenance of existing devices.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an adjustable speed addition device for feed-grade animal fats, including a support frame 1. A speed adjustment mechanism 3 is detachably installed on the top of the support frame 1. The speed adjustment mechanism 3 includes a feeding hopper 31, a discharge pipe 32, and a sealing block 37. The discharge pipe 32 is fixedly installed at the bottom of the feeding hopper 31. A conical cavity 36 is opened inside the discharge pipe 32. The sealing block 37 is inserted into the conical cavity 36. A transmission rod 38 is fixedly connected to the top of the sealing block 37. A servo motor 35 is set at the center of the feeding hopper 31. A threaded rod 311 is fixedly connected to the output end of the servo motor 35. The threaded rod 311 is threadedly connected to the transmission rod 38. A threaded cavity 310 is opened at the junction of the transmission rod 38 and the threaded rod 311. The length of the threaded cavity 310 is more than twice that of the threaded rod 311.

[0018] The specific settings and functions of this embodiment will be described in detail below. During operation, after the servo motor 35 starts, it drives the threaded rod 311 to rotate. Due to the threaded connection between the threaded rod 311 and the transmission rod 38, the rotation of the threaded rod 311 is converted into the linear motion of the transmission rod 38. The transmission rod 38 then drives the sealing block 37 to move up and down in the conical cavity 36 of the discharge pipe 32. By adjusting the position of the sealing block 37 in the conical cavity 36, the gap between them is changed. The gap size determines the speed at which animal fat flows out from the hopper 31 through the discharge pipe 32. At the same time, the sufficient length of the threaded cavity 310 ensures that the transmission rod 38 has sufficient travel. This allows for effective regulation of the oil addition rate and precise control of the position of the sealing block 37 within the conical cavity 36 of the discharge pipe 32. This enables precise adjustment of the animal oil addition rate, meeting the precise requirements for oil addition in different feed production scenarios. The length of the threaded cavity 310 is set to be more than twice that of the threaded rod 311, providing a larger range of movement for the transmission rod 38. This allows the sealing block 37 to adjust the gap with the conical cavity 36 within a wider range, thereby achieving a wider range of oil addition rate adjustment, improving the applicability of the device, ensuring the continuity and stability of the oil addition process, and reducing the impact of addition rate fluctuations on feed quality.

[0019] Example 2: Figure 1 , Figure 2 and Figure 3 As shown, a support plate 33 is fixedly installed on the top of the hopper 31, and a limit plate 34 is fixedly installed on the edge of the support plate 33. The servo motor 35 is connected to the limit plate 34 by bolts. Fixed rods 5 are symmetrically installed on both sides of the support frame 1. The ends of the fixed rods 5 are connected to the outer wall of the discharge pipe 32 by bolts. A connecting base plate 2 is fixedly installed at the bottom of the support frame 1. A reinforcing frame 4 is fixedly installed at the top of the support frame 1. Guide rods 39 are symmetrically installed on both sides of the transmission rod 38. The guide rods 39 are slidably connected to the support plate 33.

[0020] The overall effect of this embodiment is that the support plate 33 provides a mounting base for the servo motor 35, which is fixed by bolts to the limiting plate 34 to ensure stable operation. The guide rod 39 is slidably connected to the support plate 33. When the transmission rod 38 moves linearly with the threaded rod 311, the guide rod 39 slides along the support plate 33 to limit the rotation of the transmission rod 38 and ensure that it drives the sealing block 37 to move up and down smoothly. The fixed rods 5 symmetrically installed on both sides of the support frame 1 are connected to the outer wall of the discharge pipe 32 by bolts. Together with the reinforcing frame 4 at the top of the support frame 1, they assist in fixing the speed regulating mechanism 3. At the same time, the connecting base plate 2 fixed at the bottom of the support frame 1 serves as an installation structure, allowing this device to be installed on different carriers.

[0021] The usage and working principle of this device: Install this device on the required feed production carrier. The discharge pipe 32 is connected to the feeding device. Start the servo motor 35 to drive the threaded rod 311 fixedly connected to its output end. The rotation of the threaded rod 311 is converted into the linear motion of the transmission rod 38, so that the sealing block 37 moves up and down in the conical cavity 36 of the discharge pipe 32. By adjusting the position of the sealing block 37 in the conical cavity 36, the gap between the sealing block 37 and the conical cavity 36 is changed, thereby adjusting the speed at which animal fat flows out from the hopper 31 through the discharge pipe 32 to meet the needs of feed production.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
