Description

Technical Field

[0001] This utility model relates to a sieving device, specifically a feed processing sieving device, belonging to the technical field of feed processing equipment. Background Technology

[0002] Feed is a general term for the food of all domesticated animals. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. The processing of feed involves steps such as raw material screening, mixing, drying, and pelleting.

[0003] However, in the feed processing process, the screen area in existing screening equipment is usually large, while the feeding port of the hopper for adding coarse materials is usually fixed. This results in low utilization of the screen, which in turn reduces screening efficiency and increases the probability of local screen blockage. On the other hand, if the feeding port of the hopper is small, hopper blockage may also occur. Utility Model Content

[0004] The purpose of this invention is to provide a feed processing sieving device to solve the above problems. By installing a rotatable "Z"-shaped feed pipe at the end of the hopper, the feeding range can be increased, thereby improving the utilization rate of the screen area and reducing the local accumulation of coarse material on the screen. At the same time, the rotation of the feed pipe can also prevent the coarse material in the hopper from clogging.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a feed processing sieving device includes a machine body, a sieving structure on the top side of the machine body, the sieving structure including a hopper, the hopper being fixedly connected to the top side of the machine body, a discharge pipe being rotatably connected to the bottom end of the hopper, the discharge pipe having a "Z" shaped structure, a drive shaft being rotatably connected to the side of the machine body, a first pulley being fixedly connected to the end of the drive shaft, a second pulley being fixedly connected to the end of the discharge pipe, a transmission belt being sleeved between the first pulley and the second pulley, a mounting frame being provided on the bottom side of the discharge pipe, a sieve plate being provided in the middle of the mounting frame, and a cleaning structure being connected between the mounting frame and the sieve plate.

[0006] Preferably, two guide rods are fixedly connected in parallel to the inner side of the body, and the two sides of the mounting frame are slidably connected to the guide rods.

[0007] Preferably, the top side of the mounting frame is slidably connected to the machine body, the length of the mounting frame is less than the width of the inner side of the machine body, and a first spring is fixedly connected between one side of the mounting frame and the machine body.

[0008] Preferably, a first gear is fixedly connected to the bottom end of the drive shaft, a second gear meshes with the side of the first gear, the second gear is rotatably connected to the machine body, and the diameter of the second gear is smaller than the diameter of the first gear.

[0009] Preferably, the mounting frame has a pushing groove on the side close to the drive shaft, and the bottom side of the second gear has a cylindrical protrusion. The side of the protrusion on the bottom side of the second gear abuts against the mounting frame through the pushing groove.

[0010] Preferably, the cleaning structure includes an ejector rod, which is slidably connected to the side of the machine body, and the end of the ejector rod abuts against the side of the mounting frame.

[0011] Preferably, an operating lever is rotatably connected to the side of the machine body, and a limiting groove is formed in the middle of the operating lever. The operating lever is slidably connected to the ejector rod through the limiting groove.

[0012] Preferably, a torsion spring is fixedly connected between the end of the operating lever and the machine body, and a side cover is provided on the side of the machine body, the side cover being located on the top side of the mounting frame.

[0013] Preferably, the sieve plate and the mounting frame are rotatably connected, one top side of the sieve plate abuts against the machine body, a positioning groove is provided on the side of the sieve plate, a positioning block is slidably connected to the side of the mounting frame, a second spring is fixedly connected between the positioning block and the mounting frame, and the end of the positioning block abuts against the sieve plate through the positioning groove.

[0014] The beneficial effects of this utility model are as follows: the transmission effect of the first pulley, the second pulley, and the transmission belt will drive the discharge pipe at the bottom of the hopper to rotate. The discharge pipe has a "Z" shaped structure. During the rotation of the discharge pipe, the coarse material will be thrown in a ring towards the screen plate on the bottom side, so that the coarse material covers the screen plate area as much as possible to achieve higher screening efficiency. The middle part of the discharge pipe has an inclined structure. At the same time, combined with the continuous rotation of the discharge pipe itself, it is difficult for the coarse material to be blocked when passing through the discharge pipe, thus ensuring the smooth flow of the coarse material.

[0021] 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.

[0022] Please see Figures 1-5 As shown, a feed processing sieving device includes a body 1. A sieving structure 2 is provided on the top side of the body 1. The sieving structure 2 includes a hopper 201. The hopper 201 is fixedly connected to the top side of the body 1. A discharge pipe 203 is rotatably connected to the bottom end of the hopper 201. The discharge pipe 203 has a "Z" shaped structure. A drive shaft 202 is rotatably connected to the side of the body 1. A first pulley 204 is fixedly connected to the end of the drive shaft 202. A second pulley 206 is fixedly connected to the end of the discharge pipe 203. A transmission belt 205 is sleeved between the first pulley 204 and the second pulley 206. An installation frame 207 is provided on the bottom side of the discharge pipe 203. A screen plate 208 is provided in the middle of the installation frame 207. A cleaning structure 3 is connected between the installation frame 207 and the screen plate 208.

[0023] As a technical optimization of this utility model, two guide rods 213 are fixedly connected in parallel to the inner side of the body 1. The two sides of the mounting frame 207 are slidably connected to the guide rods 213, and the top side of the mounting frame 207 is slidably connected to the body 1. The length of the mounting frame 207 is less than the width of the inner side of the body 1. A first spring 211 is fixedly connected to one side of the mounting frame 207 and the body 1. A first gear 209 is fixedly connected to the bottom end of the drive shaft 202. A second gear 210 meshes with the side of the first gear 209. The second gear 210 is rotatably connected to the body 1, and the diameter of the second gear 210 is smaller than the diameter of the first gear 209. A pushing groove 212 is provided on the side of the mounting frame 207 close to the drive shaft 202, and a cylinder is provided on the bottom side of the second gear 210. The second gear 210 has a raised section on its bottom side, which abuts against the mounting frame 207 via a pushing groove 212. The mounting frame 207, which houses the screen plate 208, can slide laterally via a guide rod 213. After coarse material is fed onto the surface of the screen plate 208 via the feed pipe 203, the first gear 209 at the bottom of the drive shaft 202 drives the second gear 210 to rotate. The raised structure on the bottom side of the second gear 210, as the second gear 210 rotates, periodically pushes the mounting frame 207 to one side via the pushing groove 212. This, combined with the first spring 211 connecting the mounting frame 207 and the machine body 1, achieves the effect of oscillating the screen plate 208. Since the diameter of the first gear 209 is larger than that of the second gear 210, the screen plate 208 can have a faster vibration frequency, improving the screening effect for coarse material.

[0024] As a technical optimization of this utility model, the cleaning structure 3 includes an ejector rod 303. The ejector rod 303 is slidably connected to the side of the machine body 1. The end of the ejector rod 303 abuts against the side of the mounting frame 207. An operating rod 302 is rotatably connected to the side of the machine body 1. A limiting groove 305 is formed in the middle of the operating rod 302. The operating rod 302 is slidably connected to the ejector rod 303 through the limiting groove 305. A torsion spring 304 is fixedly connected between the end of the operating rod 302 and the machine body 1. A side cover 301 is provided on the side of the machine body 1. The side cover 301 is located on the mounting frame 207. On the top side of frame 207, the screen plate 208 is rotatably connected to the mounting frame 207. One top end of the screen plate 208 abuts against the machine body 1. A positioning groove 306 is provided on the side of the screen plate 208. A positioning block 307 is slidably connected to the side of the mounting frame 207. A second spring 308 is fixedly connected between the positioning block 307 and the mounting frame 207. The end of the positioning block 307 abuts against the screen plate 208 through the positioning groove 306. After a long period of screening, a large amount of large coarse material will accumulate on the surface of the screen plate 208. In order to facilitate its collection and simultaneously clean the screen plate 208... 8. Clean the screen plate 208 to prevent excessive clogging. The user can rotate the operating lever 302 on one side of the machine body 1. The limiting groove 305 in the middle of the operating lever 302 will push the ejector rod 303 inward into the machine body 1. At this time, the end of the ejector rod 303 will further push the mounting frame 207. As the mounting frame 207 slides, the top side of the screen plate 208 in the middle of the mounting frame 207 will be separated from the direct contact with the machine body 1. At this time, the user can open the side cover 301 on the side of the machine body 1 to rotate and flip the screen plate 208, making it easy to remove the coarse material on the screen plate 208. Meanwhile, flipping the screen plate 208 makes it easier to clean the screen plate 208, ensuring a good screening effect. In order to facilitate the reset of the screen plate 208 after cleaning, the side of the screen plate 208 is provided with a positioning groove 306. The positioning block 307 on the side of the mounting frame 207 can position the screen plate 208 in a horizontal state. After cleaning, after the screen plate 208 is restored to a horizontal state, the operating rod 302 is released. Under the push of the first spring 211, the mounting frame 207 will return to its position, and then the screen plate 208 will be re-fixed by the abutment between it and the inside of the machine body 1.

[0025] In use, this invention firstly has a hopper 201 for feeding material located on the top side of the machine body 1. A drive shaft 202 driven by a motor is located on one side of the hopper 201. When coarse material is fed into the machine body 1 through the hopper 201, the drive shaft 202 rotates due to the motor's rotation. This rotation, achieved through the transmission of the first pulley 204, the second pulley 206, and the transmission belt 205, causes the discharge pipe 203 at the bottom of the hopper 201 to rotate. The discharge pipe 203 has a "Z"-shaped structure. During rotation, the discharge pipe 203 throws the coarse material in a ring towards the bottom screen plate 208, maximizing the coverage of the screen plate 208 for higher screening efficiency. The middle section of the discharge pipe 203 has an inclined structure, which, combined with the discharge pipe... The continuous rotation of the 203 itself makes it difficult for coarse material to get clogged when passing through the feed pipe 203, thus ensuring smooth flow of coarse material. The mounting frame 207 of the screen plate 208 can slide laterally through the guide rod 213. After the coarse material is fed onto the surface of the screen plate 208 through the feed pipe 203, the first gear 209 at the bottom of the drive shaft 202 will drive the second gear 210 to rotate. The protruding structure on the bottom side of the second gear 210 will periodically push the mounting frame 207 to one side through the pushing groove 212 as the second gear 210 rotates. With the first spring 211 connecting the mounting frame 207 and the machine body 1, the screen plate 208 will be vibrated. Since the diameter of the first gear 209 is larger than that of the second gear 210, the screen plate 208 will vibrate. The 10mm diameter allows the screen plate 208 to have a faster vibration frequency, improving the screening effect for coarse materials. After prolonged screening, a large amount of large coarse particles will accumulate on the surface of the screen plate 208. To facilitate collection and cleaning of the screen plate 208 and prevent excessive clogging of the pores, the user can rotate the operating lever 302 on one side of the machine body 1. The limiting groove 305 in the middle of the operating lever 302 will push the ejector rod 303 inward towards the machine body 1. At this time, the end of the ejector rod 303 will further push the mounting frame 207. As the mounting frame 207 slides, the top side of the screen plate 208 in the middle of the mounting frame 207 will be separated from the direct contact state with the machine body 1. At this time, the user can start the machine. The side cover 301 on the side of the machine body 1 rotates and flips the screen plate 208, making it easy to remove coarse materials from the screen plate 208. At the same time, flipping the screen plate 208 also makes it easier to clean the screen plate 208, ensuring a good screening effect. In order to facilitate the reset of the screen plate 208 after cleaning, the side of the screen plate 208 is provided with a positioning groove 306. The positioning block 307 on the side of the mounting frame 207 can position the screen plate 208 in a horizontal state. After cleaning, the screen plate 208 is restored to a horizontal state and the operating lever 302 is released. Under the push of the first spring 211, the mounting frame 207 will return to its position, and then the screen plate 208 will be re-fixed by the abutment between it and the inside of the machine body 1.
