Description

Technical Field

[0001] This utility model belongs to the field of feed processing technology, specifically relating to a powder cleaning sieve used in the feed preparation process. Background Technology

[0002] Feed ingredients contain large particles such as straw, stalks, burlap, paper scraps, and clumps. To improve feed quality, feed ingredients are usually sorted and cleaned using a powder cleaning sieve to remove large particles.

[0003] For example, a Chinese patent discloses a powder cleaning screen for fish feed production (publication number CN220160490U), which includes a screen box and a support platform. A feed pipe is inserted into the top of the screen box, and two vibration motors are fixedly connected at symmetrical positions on the two side walls of the screen box. Several spring assemblies are fixedly connected to the top of the screen box near the support platform.

[0004] However, the aforementioned publicly available document describes a system with a booster pump, pipe one, pipe two, support plate one, and booster nozzles. The booster pump is screwed to the top of support plate one to support it. Vibration damping pads reduce vibration and prevent damage to the booster pump. The booster pump delivers pressurized water through pipes one and two, and the pressurized water inside pipe two is sprayed out through the booster nozzles to wash the screen. However, in practice, the spring assembly is prone to metal fatigue and loss of elasticity over time, resulting in poor screening performance and hindering long-term use and widespread adoption.

[0005] To address these issues, those skilled in the art have provided a powder cleaning sieve for use in the feed preparation process. Utility Model Content

[0006] The purpose of this invention is to provide a powder cleaning screen for use in the feed preparation process, which can solve the problems mentioned in the background art.

[0007] The specific technical solution adopted in this utility model is as follows:

[0008] A powder cleaning screen for feed preparation includes a base plate. Two pairs of support plates are fixed to the right end of the outer top surface of the base plate. Two sliding rods are fixed between the two pairs of support plates. Sliding blocks are slidably sleeved on the outer walls of the two sliding rods. A screening box is fixed to the outer top surface of the two sliding blocks. A screen is fixed inside the screening box. A through-type discharge port is opened on the right outer wall of the screening box corresponding to the screen. A through-type discharge port is opened on the right end of the outer bottom surface of the screening box. A feed hood is fixed and connected to the left end of the outer top surface of the screening box. A displacement component for driving the screening box to move back and forth is provided at the center of the outer top surface of the base plate.

[0009] The displacement assembly includes L-shaped connecting plates symmetrically positioned at the center of the outer top surface of the base plate. A round rod is fixed between the two L-shaped connecting plates. A vertical block is slidably sleeved on the outside of the round rod. Square blocks are fixed to the top of the outer walls on both sides of the vertical block. The two square blocks are threadedly fixed to the screening box by bolts. Return springs are sleeved on both ends of the outer circumference of the round rod. One end of each return spring is fixedly connected to the outer walls on both sides of the vertical block, while the opposite end is fixedly connected to the outer walls of the two L-shaped connecting plates. The two L-shaped connecting plates are threadedly fixed to the base plate by bolts.

[0010] The present invention is further configured such that: a U-shaped frame is fixed to the left end of the outer top surface of the base plate, a rotating shaft is rotatably mounted on the outer top surface of the U-shaped frame, a disc is fixedly sleeved on the outer peripheral side wall of the rotating shaft, and a U-shaped sleeve is fixedly mounted on the left outer wall of the screening box.

[0011] The present invention is further configured such that: a cylinder is fixedly installed on the outer top surface of the disc; a connecting plate is rotatably installed on the outer peripheral side wall of the cylinder; one end of the connecting plate away from the cylinder is rotatably connected to the inside of the U-shaped sleeve; a drive motor is fixedly installed on the outer top surface of the base plate and inside the U-shaped frame; one end of the rotating shaft extends rotatably into the inside of the U-shaped frame and is fixedly connected to the output end of the drive motor.

[0012] The present invention is further configured such that: the left outer wall of the feeding hood has a through-type opening, and a sealing plate is slidably connected to the inner side of the opening; one end of the sealing plate extends into the interior of the feeding hood, and the other end extends into the exterior of the feeding hood and is fixed with a square plate; a U-shaped plate is fixed to the left outer wall of the feeding hood; a threaded rod is rotatably installed on the left outer wall of the U-shaped plate; a knob is fixed to one end of the threaded rod, and the other end rotatably passes through the U-shaped plate and is rotatably connected to the outer wall of the square plate.

[0013] The present invention is further configured such that: a discharge square tube is fixedly installed on the right outer wall of the screening box at one point corresponding to the discharge port, and a discharge square tube is fixedly installed on the right end of the outer bottom surface of the screening box at one point corresponding to the discharge port.

[0014] The present invention is further configured such that: each of the four corners of the outer top surface of the base plate is provided with a through-hole screw hole.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This utility model discloses a powder cleaning screen for use in the feed preparation process. It uses a drive motor as a power source to drive a rotating shaft to rotate a circular plate. This causes the connecting plate to move the screening box back and forth along the outer wall of the slide bar. With the assistance of vertical blocks, return springs, and circular rods, it generates a stable vibration effect during the lateral movement, thereby ensuring the efficiency and effect of feed screening. It also facilitates disassembly and assembly later.

[0017] This utility model relates to a powder cleaning screen used in the feed preparation process. Through the interaction of a square plate, a U-shaped plate, and a threaded rod, a sealing plate can be driven to slide inside the opening, thereby opening and closing the feed hood. This prevents excessive feed from being conveyed, which could lead to insufficient screening and poor results, thus improving practicality. Attached Figure Description

[0026] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1 As shown, a powder cleaning screen for feed preparation includes a base plate 1. Each of the four corners of the outer top surface of the base plate 1 has through-hole screw holes 402. Tightening the bolts in the screw holes 402 fixes the base plate 1 to the working area, ensuring the operational stability of subsequent equipment. Two pairs of support plates 101 are fixed to the right end of the outer top surface of the base plate 1. Two sliding rods 102 are fixed between the two pairs of support plates 101. Sliding sliders 103 are slidably sleeved on the outer walls of the two sliding rods 102. A screening box 104 is fixed to the outer top surfaces of the two sliding sliders 103. By sliding the sliding sliders 103 on the outer walls of the sliding rods 102, the screening box 104 can move back and forth horizontally, ensuring stability during the reciprocating motion.

[0028] The screening box 104 has a screen 105 fixed inside (the screen 105 is designed to be inclined to facilitate the screening of feed). A through-hole 106 is opened on the right outer wall of the screening box 104 corresponding to the screen 105. A discharge square tube 4 is fixedly installed on the right outer wall of the screening box 104 corresponding to the discharge port 106. A through-hole 107 is opened at the right end of the outer bottom surface of the screening box 104. A discharge square tube 401 is fixedly installed at the right end of the outer bottom surface of the screening box 104 corresponding to the discharge port 107. The top left end is fixed and connected to the feed hood 108. In use, the feed is first conveyed along the feed hood 108 into the screening box 104, and then screened through the screen 105. Large particles of feed impurities are intercepted on the screen 105 and discharged through the discharge port 106 and the discharge pipe 4. Small particles of feed fall into the inner bottom surface of the screening box 104 through the filter holes on the screen 105. Since the inner bottom surface is inclined, the feed will slide to the outlet port 2 and be discharged along the discharge pipe 401, thus achieving the screening effect.

[0029] A displacement assembly 2 for driving the screening box 104 to move back and forth is provided at the center of the outer top surface of the base plate 1. The displacement assembly 2 includes L-shaped connecting plates 201 symmetrically arranged at the center of the outer top surface of the base plate 1. A round rod 202 is fixed between the two L-shaped connecting plates 201. A vertical block 203 is slidably sleeved on the outside of the round rod 202. A square block 204 is fixed to the top of the outer wall on both sides of the vertical block 203. The two square blocks 204 are threadedly fixed to the screening box 104 by bolts. Return springs 205 are sleeved on both ends of the outer circumference of the round rod 202. One end of the two return springs 205 is fixedly connected to the outer wall on both sides of the vertical block 203, while the opposite end is fixedly connected to the outer wall of the two L-shaped connecting plates 201. The two L-shaped connecting plates 201 are threadedly fixed to the base plate 1 by bolts. The bolted connection facilitates replacement of the return spring 205 when it loses its elasticity. A U-shaped frame 206 is fixed to the left end of the outer top surface of the base plate 1. A rotating shaft 207 is rotatably mounted on the outer top surface of the U-shaped frame 206. A disc 208 is fixedly sleeved on the outer peripheral side wall of the rotating shaft 207. A U-shaped sleeve 209 is fixedly mounted on the left outer wall of the screening box 104. A cylinder 210 is fixedly mounted on the outer top surface of the disc 208. A connecting plate 211 is rotatably mounted on the outer peripheral side wall of the cylinder 210. The end of the connecting plate 211 away from the cylinder 210 is rotatably connected to the inside of the U-shaped sleeve 209. A drive motor 212 is fixedly mounted on the outer top surface of the base plate 1 and inside the U-shaped frame 206. One end of the rotating shaft 207 extends rotatably into the inside of the U-shaped frame 206 and is fixedly connected to the output end of the drive motor 212. The drive motor 212 is controlled and started to drive the rotating shaft 207 to drive the disc 208 to rotate on the U-shaped frame 206. This causes the cylinder 210 to drive the connecting plate 211 to push the screening box 104 to move back and forth along the outer wall of the rod 202 through the U-shaped sleeve 209. During the back and forth movement, the reset spring 205 is repeatedly squeezed to extend and retract, generating elastic force, which in turn causes the screening box 104 to vibrate. This improves the efficiency and effect of feed screening and increases its practicality.

[0030] The left outer wall of the feed hood 108 has a through-type opening 3. A sealing plate 301 is slidably connected to the inner side of the opening 3. One end of the sealing plate 301 extends into the interior of the feed hood 108, while the other end extends into the exterior of the feed hood 108 and is fixed with a square plate 302. A U-shaped plate 303 is fixed to the left outer wall of the feed hood 108. A threaded rod 304 is rotatably installed on the left outer wall of the U-shaped plate 303. A knob 305 is fixed to one end of the threaded rod 304, while the other end rotates through the U-shaped plate 303 and is rotatably connected to the outer wall of the square plate 302. When conveying feed, the knob 305 can be turned to drive the threaded rod 304 to rotate on the U-shaped plate 303, thereby pushing the square plate 302 to drive the sealing plate 301 to slide inside the opening 3, so that the sealing plate 301 can open and close the feed hood 108, avoiding excessive feed conveying, which would lead to insufficient screening and poor effect, thus improving practicality.

[0031] The working principle of this utility model is as follows: When in use, feed is first put into the inside of the feed box 108, and then the knob 305 is turned to drive the threaded rod 304 to rotate, thereby driving the sealing plate 301 to slide inside the opening 3, thereby opening the feeding channel of the feed box 108 and conveying the feed into the screening box 104.

[0032] At the same time, the drive motor 212 is started to drive the rotating shaft 207 to drive the disc 208 to rotate on the U-shaped frame 206, so that the cylinder 210 drives the connecting plate 211 to push the screening box 104 to move back and forth along the outer wall of the rod 202 through the U-shaped sleeve 209. During the back and forth movement, the reset spring 205 is repeatedly squeezed to extend and retract and generate elastic force, thereby making the screening box 104 vibrate.

[0033] At the same time, the feed is screened by screen 105. Large particles of feed impurities are intercepted on screen 105 and discharged through discharge port 106 and discharge square pipe 4. Small particles of feed fall into the inner bottom of screening box 104 through the filter holes on screen 105 and slide to outlet 2, and are discharged along discharge square pipe 2 401, thus achieving screening.

[0034] It should be noted that all electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
