Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, and in particular relates to a vibrating screen for feed production. Background Technology

[0002] In feed production, the quality of raw materials directly determines the nutritional balance and safety of the finished feed. However, core raw materials such as corn, soybean meal, and wheat bran often contain impurities, lumps, or uneven particle size. If they are directly used for mixing and processing, they can easily lead to an imbalance in the distribution of nutrients in the feed and may also damage subsequent pelleting equipment, affecting production efficiency and product quality. To solve this problem, vibrating screens have become a key pretreatment device in the feed production process. Relying on the high-frequency vibration generated by the vibrating motor, combined with screens of different apertures, it can efficiently separate impurities in raw materials and screen out materials that meet the particle size requirements. It can not only purify raw materials and ensure the smooth progress of subsequent processing, but also lay the foundation for precise ingredient formulation. It is an important piece of equipment for improving the standardization of feed production and ensuring feed quality.

[0003] However, existing vibrating screens are not easy to adjust the tilt angle of the screen plate during use. This means that when dealing with materials with high particle viscosity, a smaller angle will cause the material to accumulate, while when dealing with easily dispersed materials, a larger angle will cause the material to slide out of the screen plate quickly. This not only reduces screening efficiency but also reduces screening quality. Utility Model Content

[0004] The purpose of this utility model is to provide a vibrating screen for feed production. By setting an adjustment part, it solves the problem that existing vibrating screens are not easy to adjust the tilt angle of the screen plate during use. This causes the material to accumulate when facing materials with high particle viscosity, while the material slides out of the screen plate quickly when facing materials that are easy to disperse. This not only reduces screening efficiency but also reduces screening quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a vibrating screen for feed production, comprising a housing and a partition fixedly connected to the inner wall of the housing, and further comprising: an adjustment part installed inside the housing; a vibration part located on the right side of the partition; the adjustment part including a rotating assembly installed inside the housing; and a limiting assembly installed inside the housing; the rotating assembly including a fixed shaft fixedly connected to the inner wall of the housing, a bracket rotatably connected to the outer wall of the fixed shaft, a spiral spring fixedly connected to the inner wall of the bracket, the inner ring of the spiral spring being fixedly connected to the fixed shaft, a screen plate fixedly connected to the inner wall of the bracket, and a protective shell fixedly connected to the top of the bracket, the protective shell being an inverted C-shaped block on the bracket. Through the rotational cooperation between the fixed shaft and the bracket, and the resetting action of the spiral spring, the rotation and automatic resetting of the screen plate are achieved, while the protective shell protects the relevant components.

[0006] Furthermore, the vibration unit includes a swaying component disposed at the bottom of a support; and a power component mounted at the bottom of the support, the power component being used to provide power for the vibration of the swaying component.

[0007] Furthermore, the limiting component includes two sliding grooves formed on the inner wall of the housing. A second bracket is slidably connected to the inner wall of the two sliding grooves. An electric telescopic rod is fixedly connected to the bottom inner wall of the housing. The top of the electric telescopic rod is fixedly connected to the second bracket. Two limiting slots are formed within the first bracket. Several elastic elements are provided within the second bracket. Two fixed shafts are mirror images of each other. The second bracket is located within the two limiting slots, which are mirror images of each other. The elastic elements are arranged in an array. Each elastic element includes a slider slidably connected to the inner wall of the second bracket. Several first springs are fixedly connected to the inner wall of the slider. The side of each first spring away from the slider is fixedly connected to the second bracket. The first springs are arranged in an array. The electric telescopic rod drives the second bracket to slide along the sliding grooves. Combined with the buffering effect of the elastic elements within the second bracket, the rotation angle of the first bracket is flexibly and stably limited.

[0008] Furthermore, the swaying assembly includes a bracket three fixedly connected to the bottom of the bracket one. Two brackets four are disposed within the bracket three, and each of the two brackets four contains a vibrating element. The two brackets four and the two vibrating elements are mirror images of each other. Each vibrating element includes a limiting rod fixedly connected to the inner wall of the bracket three. The limiting rod passes through the bracket four, and its outer wall is slidably connected to the bracket four. Two springs two are sleeved on the outer wall of the limiting rod. The sides of the two springs two that are close to each other are fixedly connected to the bracket four, and the sides of the two springs two that are far apart from each other are fixedly connected to the bracket three. The two springs two are mirror images of each other. Through the sliding cooperation between the limiting rod in the bracket three and the bracket four, and the elastic action of the springs two, the driving force of the power assembly is converted into the vibration of the bracket one, while ensuring the stability of the vibration.

[0009] Furthermore, the power assembly includes a bracket five fixedly connected between two brackets four. A motor is fixedly connected to the inner wall of the bracket five. A rotating component is provided inside the bracket five. The rotating component includes a rotating shaft rotatably connected to the inner wall of the bracket five. The output shaft of the motor is fixedly connected to the rotating shaft through a coupling. An eccentric block is fixedly connected to the outer wall of the rotating shaft. The eccentric block is located on the side of the bracket five away from the motor. The motor drives the rotating shaft to rotate the eccentric block. The centrifugal force generated by the rotation of the eccentric block provides continuous vibration power for the shaking assembly.

[0010] This utility model has the following beneficial effects: 1. By setting an adjustment unit, when the electric telescopic rod is started, it drives the second bracket to move up and down along the slide groove. The slider pushes the first bracket to rotate around the fixed axis, and the spiral spring rewinds or resets accordingly, thereby realizing the adjustment of the screen plate tilt angle. The first spring buffers to avoid jamming, and the protective shell prevents materials from falling in and affecting operation. It can adjust the tilt angle of the screen plate. When facing materials with high particle viscosity, the tilt angle of the screen plate can be increased to avoid material accumulation. When facing easily scattered materials, the tilt angle of the screen plate can be decreased to prevent materials from sliding out of the screen plate quickly. This not only ensures screening efficiency but also improves screening quality. 2. By setting up a vibrating part, when the motor drives the rotating shaft to rotate the eccentric block, it will cause the fifth bracket to shake, causing the fourth bracket to slide along the limit rod, compressing or stretching the second spring, which is transmitted to the first bracket through the third bracket. Combined with the spiral spring and the first spring, the screen plate will generate continuous high-frequency vibration to complete the screening. It can drive the screen plate to vibrate continuously, so that it can screen the material evenly, and the normal vibration screening will not be affected by the adjustment part, thus ensuring the stable operation of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-7 As shown, this utility model is a vibrating screen for feed production, including a housing 101 and a partition 102 fixedly connected to the inner wall of the housing 101. It also includes: an adjustment part 2, which is installed inside the housing 101; and a vibration part 3, which is located on the right side of the partition 102.

[0017] The adjustment unit 2 includes a rotating assembly 21 disposed within the housing 101; and a limiting assembly 22 installed within the housing 101. The rotating assembly 21 includes a fixed shaft 211 fixedly connected to the inner wall of the housing 101. A first bracket 212 is rotatably connected to the outer wall of the fixed shaft 211. A spiral spring 213 is fixedly connected to the inner wall of the first bracket 212, with its inner ring fixedly connected to the fixed shaft 211. A sieve plate 214 is fixedly connected to the inner wall of the first bracket 212, and a protective shell 215, which is an inverted C-shaped block, is fixedly connected to the top of the first bracket 212. The limiting assembly 22 includes two sliding grooves 221 formed on the inner wall of the housing 101. A second bracket 222 is slidably connected to the inner walls of the two sliding grooves 221. An electric telescopic rod 223 is fixedly connected to the bottom inner wall of the housing 101, with its top fixedly connected to the second bracket 222. The first support 212 has two limiting grooves 224, and the second support 222 has several elastic elements. The two fixed shafts 211 are mirror images of each other. The second support 222 is located in the two limiting grooves 224, which are mirror images of each other. The elastic elements are arranged in an array. The elastic elements include a slider 225 that is slidably connected to the inner wall of the second support 222. Several springs 226 are fixedly connected to the inner wall of the slider 225. The side of the springs 226 away from the slider 225 is fixedly connected to the second support 222. The springs 226 are arranged in an array. By setting the adjustment part 2, the tilt angle of the screen plate 214 can be adjusted. When dealing with materials with high particle viscosity, the tilt angle of the screen plate 214 can be increased to avoid material accumulation. When dealing with easily dispersed materials, the tilt angle of the screen plate 214 can be decreased to prevent the material from sliding out of the screen plate 214 quickly. This not only ensures screening efficiency but also improves screening quality.

[0018] The vibrating part 3 includes a swaying component 31, which is disposed at the bottom of the support 212; and a power component 32, which is also disposed at the bottom of the support 212 and provides power for the vibration of the swaying component 31. The swaying component 31 includes a support 311 fixedly connected to the bottom of the support 212. Two supports 412 are disposed inside the support 311, and each of the two supports 412 contains a vibrating element. The two supports 412 and the two vibrating elements are mirror images of each other. Each vibrating element includes a limiting rod 313 fixedly connected to the inner wall of the support 311. The limiting rod 313 passes through the support 412, and its outer wall is slidably connected to the support 412. Two springs 214 are sleeved on the outer wall of the limiting rod 313, and the sides of the two springs 214 that are close to each other are fixed to the support 412. The two springs 314 are fixedly connected to the bracket 311 on opposite sides. The two springs 314 are mirror images of each other. The power assembly 32 includes a bracket 321 fixedly connected between the two brackets 312. A motor 322 is fixedly connected to the inner wall of the bracket 321. A rotating component is provided inside the bracket 321. The rotating component includes a rotating shaft 323 rotatably connected to the inner wall of the bracket 321. The output shaft of the motor 322 is fixedly connected to the rotating shaft 323 through a coupling. An eccentric block 324 is fixedly connected to the outer wall of the rotating shaft 323. The eccentric block 324 is located on the side of the bracket 321 away from the motor 322. By setting the vibration part 3, the screen plate 214 can be driven to vibrate continuously, so that the material is screened evenly. Moreover, the normal vibration screening will not be affected by the adjustment part 2, thus ensuring the stable operation of the device.

[0019] It should be noted that the control of the electric telescopic rod 223 and the motor 322 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0020] A specific application of this embodiment is as follows: When it is necessary to reduce the tilt angle of the sieve plate 214, the electric telescopic rod 223 can be activated, causing its output shaft to drive the second support 222 to move downward within the two sliding grooves 221. Simultaneously, as the second support 222 moves, it also drives the first support 212 to rotate around the fixed shaft 211 via several sliders 225. At this time, the spiral spring 213 will coil and generate elastic force. When the first support 212 rotates around the fixed shaft 211, the tilt angle of the sieve plate 214 will decrease. To increase the tilt angle of the sieve plate 214, the electric telescopic rod 223 can be moved in the opposite direction, causing the second support 222 to move upward within the two sliding grooves 221. At this time, under the elastic force of the spiral spring 213, the first support 212 will rotate in the opposite direction around the fixed shaft 211, thereby increasing the tilt angle of the sieve plate 214. While adjusting the tilt of the sieve plate 214 significantly, the action of the first spring 226 and the sliders 225 will prevent the support from shifting. When frame 212 is stuck, the protective shell 215 prevents the screened material from falling into the limiting component 22 and affecting its normal operation. After adjusting the tilt angle of the screen plate 214, the empty containers for collecting the material can be placed on the left side of the machine housing 101 and the left side of the partition 102, respectively. Then the material can be poured onto the screen plate 214. At the same time, the motor 322 can be started, and its output shaft drives the eccentric block 324 to rotate through the rotating shaft 323, thereby causing the support 321 to shake. At this time, the shaking support 321 will cause the support 4 312 to slide on the limiting rod 313, thereby squeezing or stretching the spring 2 314 to generate elastic force. Finally, through the transmission of the support 3 311, the support 212 shakes. Under the action of the spiral spring 213 and the spring 1 226, the screen plate 214 will generate continuous high-frequency vibration, thereby screening the material into the containers on the left side of the machine housing 101 and the left side of the partition 102 through the screen plate 214.
