[0001] The utility model relates to the technical field of feed production, and specifically relates to a sieve grain port scraper that prevents material accumulation. BACKGROUND
[0002] Feed processing generally refers to processing raw materials through a series of processes to become products for animals, in order to facilitate animal digestion and absorption, feed is usually made into a granular structure, and in the production process of feed, the feed conveying equipment is usually used to convey the finished feed for subsequent packaging work.
[0003] Referring to the CN219751015U Chinese patent disclosed in the prior art, a sieve grain port scraper that prevents material accumulation is provided, a guide plate is arranged inside the feed cover, the guide plate is inverted V-shaped, the material slides down from both sides of the guide plate when falling, the material falls in different directions, and a certain distance is maintained between the falling materials, thereby effectively preventing the material from being blocked and pressed, and enabling the chain conveyor belt to run smoothly.
[0004] The present application designs another sieve grain port scraper that prevents material accumulation, which solves the problem that the existing belt conveyor accumulates a large amount of feed, which increases the resistance of the conveyor belt and affects the conveying efficiency. UTILITY MODEL CONTENTS
[0005] In order to overcome the shortcomings of the prior art, the utility model provides a sieve grain port scraper that prevents material accumulation, which comprises a belt conveyor for conveying feed, a feed inlet is fixed above the belt conveyor, the feed inlet is hollow in the inner cavity, the upper and lower ends are open, the size of the top opening part of the feed inlet is larger than that of the bottom opening part, the bottom of the feed inlet is above the belt conveyor, a scraper is arranged above the belt conveyor outside the feed inlet and performs scraping work on the feed sent into the belt conveyor by the feed inlet, and the scraper is connected with the feed inlet through a connecting assembly.
[0006] In order to achieve the above-mentioned purpose, the feed is poured into the feed inlet from the top opening part of the feed inlet, and is discharged from the bottom opening part of the feed inlet, the feed discharged from the feed inlet falls on the belt conveyor, the belt conveyor conveys the feed to the next process, the feed inlet provides a buffer to prevent the feed from overflowing when a large amount of feed is directly poured onto the belt conveyor, the scraper scrapes the feed on the belt conveyor to prevent the feed from accumulating during the conveying process, which increases the resistance of the conveyor belt and affects the conveying efficiency.
[0007] Furthermore, the connecting assembly includes a mounting bracket fixed to the outer wall of the feed hopper. The mounting bracket has an L-shaped mounting plate integrally formed on both its front and rear sides. A long shaft is rotatably connected to the mounting bracket. An elastic cloth is wound around the long shaft. One end of the elastic cloth is fixed to the long shaft, and the other end is fixed to a connecting plate. The scraper is disposed on the lower surface of the elastic cloth and is fixedly connected to the connecting plate and the elastic cloth. The elastic cloth extends from both the front and rear ends of the connecting plate. Ear seats are fixed to both ends of the connecting plate extending from the elastic cloth. A swing rod is hinged to the ear seat. The end of the swing rod away from the ear seat is hinged to the mounting plate.
[0008] The above technical solution uses a mounting frame to support a long shaft, which in turn supports the elastic fabric. A swing arm is used to limit the movement of the integrated elastic fabric, connecting plate, and scraper.
[0009] Furthermore, a power box located above the mounting plate is fixed to the front side of the mounting bracket. The power box has a hollow interior. One end of each long shaft extends out of the mounting bracket and is rotatably connected to the mounting bracket. The portion of the long shaft extending out of the mounting bracket enters the power box and is rotatably connected to the power box. The interior of the power box is equipped with a power assembly for controlling the rotation of the long shaft.
[0010] The above technical solution provides power through a power component, which drives the long shaft to rotate. The rotation of the long shaft will drive the rotation of the scraper to adjust the thickness of the feed on the belt conveyor.
[0011] Furthermore, the power assembly includes a turbine disposed in the inner cavity of the power box and rotatably connected to the power box. The turbine is nested on the outer side of the end of the long shaft entering the power box and is fixed coaxially with the long shaft. The inner cavity of the power box is also rotatably connected to a worm located next to the turbine and meshing with the turbine. The top end of the worm protrudes from the power box and is rotatably connected to the power box. A knob for controlling the rotation of the worm is coaxially fixed on the part of the worm protruding from the power box.
[0012] The above technical solution provides power by manually rotating a knob, which drives a worm gear fixed coaxially with the knob to rotate. The rotation of the worm gear drives a turbine gear meshing with the worm gear to rotate, and the rotation of the turbine gear drives a long shaft fixed coaxially with the turbine gear to rotate.
[0013] Furthermore, an inclined first guide plate is fixed on one side of the inner cavity wall of the feed hopper, with a gap between the lowest end of the first guide plate and the inner cavity wall of the feed hopper. An inclined second guide plate is fixed on the other side of the inner cavity wall of the feed hopper, with the second guide plate located below the first guide plate and symmetrically arranged with the first guide plate, and a gap between the lowest end of the second guide plate and the inner cavity wall of the feed hopper.
[0014] With the above technical solution, by fixing a first guide plate and a second guide plate to the inner wall of the feed hopper, the feed entering the feed hopper will first fall onto the first guide plate, slide along the first guide plate toward the lowest end of the first guide plate, and fall into the gap between the first guide plate and the feed hopper, and then fall onto the second guide plate, slide along the second guide plate toward the lowest end of the second guide plate, and fall into the gap between the second guide plate and the feed hopper, and then be discharged through the bottom opening of the feed hopper. This increases the flow path of the feed, slows down the speed at which the feed falls into the belt conveyor, and further reduces the possibility of excessive feed accumulating on the belt conveyor.
[0015] Furthermore, a plurality of first guide strips are fixed on the first guide plate, and the plurality of first guide strips are arranged in an array with the middle position of the highest point of the first guide plate as the center. A plurality of second guide strips are fixed on the second guide plate, and the plurality of second guide strips are arranged in an array with the middle position of the highest point of the second guide plate as the center. The square side direction of each first guide strip is parallel to the long side direction of the second guide strip.
[0016] Through the above technical solution, the feed falling on the first guide plate and the second guide plate is evenly distributed into the gap between the first guide plate and the second guide plate by the action of several first guide bars and second guide bars, so that the feed passing through the feed hopper is evenly spread on the belt conveyor, which is convenient for the scraper to level it.
[0017] In summary, this grain screening scraper machine for preventing material accumulation has the following beneficial effects:
[0018] (1) The feed is poured into the feed hopper through the top opening of the feed hopper and discharged from the feed hopper through the bottom opening. The feed discharged from the feed hopper falls onto the belt conveyor and is transported to the next process by the belt conveyor. The feed hopper provides a buffer to prevent a large amount of feed from being poured directly onto the belt conveyor and causing feed overflow. The scraper flattens the feed that falls onto the belt conveyor to avoid the feed from accumulating during the conveying process, which would increase the resistance of the conveyor belt and affect the conveying efficiency.
[0019] (2) The grain screening scraper machine that prevents material accumulation is powered by a power unit to drive the long shaft to rotate. The rotation of the long shaft will drive the scraper to rotate, so as to adjust the thickness of the feed on the belt conveyor.
[0020] (3) The scraper conveyor for preventing material accumulation has a first guide plate and a second guide plate fixed in the inner wall of the feed hopper. The feed entering the feed hopper will first fall on the first guide plate, slide along the first guide plate toward the lowest end of the first guide plate, fall into the gap between the first guide plate and the feed hopper, and then fall on the second guide plate. The feed will slide along the second guide plate toward the lowest end of the second guide plate, fall into the gap between the second guide plate and the feed hopper, and then be discharged through the bottom opening of the feed hopper. This increases the flow path of the feed, slows down the speed at which the feed falls into the belt conveyor, and further reduces the possibility of excessive feed accumulating on the belt conveyor.

[0030] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.
[0031] likeFigures 1-7 As shown, the preferred embodiment of this utility model is a scraper conveyor for preventing material accumulation at a grain screening port. It includes a belt conveyor 1 that transports the unloaded feed to the next process. The belt conveyor 1 can be a horizontal belt conveyor, a steep-angle belt conveyor, a Z-type belt conveyor, or other suitable types. The feed inlet of the belt conveyor 1 is located below the feed discharge port. Below the discharge port, a feed hopper 2 is located above the feed inlet of the belt conveyor 1. The feed hopper 2 has a hollow interior and openings at both the top and bottom. The size of the top opening of the feed hopper 2 is larger than the size of the bottom opening. The bottom opening of the feed hopper 2 is located above the belt conveyor 1. The bottom of the feed hopper 2 is fixed to the outer shell of the belt conveyor 1 by a support. Feed is poured into the feed hopper 2 through the top opening and discharged from the feed hopper 2 through the bottom opening. The discharged feed falls onto the belt conveyor 1 and is transported to the next process by the belt conveyor 1. The feed hopper 2 provides a buffer, preventing a large amount of feed from being directly poured onto the belt conveyor 1, causing feed overflow.
[0032] like Figure 2 and Figure 5 An inclined first guide plate 15 is fixed on one side of the inner cavity wall of the feed hopper 2. The lowest end of the first guide plate 15 leaves a gap with the inner cavity wall of the feed hopper 2. An inclined second guide plate 16 is fixed on the other side of the inner cavity wall of the feed hopper 2. The second guide plate 16 is located below the first guide plate 15 and is symmetrically arranged with the first guide plate 15. The lowest end of the second guide plate 16 leaves a gap with the inner cavity wall of the feed hopper 2.
[0033] like Figure 2 and Figure 5 By fixing a first guide plate 15 and a second guide plate 16 to the inner wall of the feed hopper 2, the feed entering the feed hopper 2 will first fall on the first guide plate 15, slide along the first guide plate 15 toward the lowest end of the first guide plate 15, fall into the gap between the first guide plate 15 and the feed hopper 2, and then fall on the second guide plate 16, slide along the second guide plate 16 toward the lowest end of the second guide plate 16, fall into the gap between the second guide plate 16 and the feed hopper 2, and then be discharged through the bottom opening of the feed hopper 2. This increases the flow path of the feed, slows down the speed at which the feed falls into the belt conveyor 1, and further reduces the possibility of excessive feed accumulating on the belt conveyor 1.
[0034] like Figure 2 and Figure 5A plurality of first guide strips 17 are fixed on the first guide plate 15. The plurality of first guide strips 17 are arranged in an array with the middle position of the highest point of the first guide plate 15 as the center. A plurality of second guide strips 18 are fixed on the second guide plate 16. The plurality of second guide strips 18 are arranged in an array with the middle position of the highest point of the second guide plate 16 as the center. The direction of the square side of each first guide strip 17 is parallel to the direction of the long side of the second guide strip 18.
[0035] like Figure 2 and Figure 5 Through the action of several first guide strips 17 and second guide strips 18, the feed falling on the first guide plate 15 and the second guide plate 16 is evenly distributed into the gap between several first guide strips 17 and the gap between several second guide strips 18, so that the feed passing through the feed hopper 2 is evenly spread on the belt conveyor 1, which is convenient for the scraper 3 to scrape it flat.
[0036] like Figure 1 and Figure 2 and Figure 3 and Figure 4 Feed falls onto the belt conveyor 1 through the bottom opening of the feed hopper 2. To prevent the feed from accumulating on the belt conveyor 1 during the conveying process, a scraper 3 is installed outside the feed hopper 2 above the belt conveyor 1 to level the feed fed from the feed hopper 2 onto the belt conveyor 1. The scraper 3 is connected to the feed hopper 2 through a connecting component. The scraper 3 levels the feed falling onto the belt conveyor 1 to prevent the feed from accumulating during the conveying process, which would increase the resistance of the conveyor belt and affect the conveying efficiency.
[0037] like Figure 3 and Figure 4 and Figure 5 and Figure 6 The connecting assembly includes a mounting frame 4 fixed to the outer wall of the feed hopper 2. The mounting frame 4 has a hollow inner cavity with openings on the left and bottom. The front and rear sides of the mounting frame 4 are integrally fitted with mounting plates 5 in the shape of an L-shape. A long shaft 6 is rotatably connected to the mounting frame 4. The center line of the long shaft 6 is perpendicular to the conveying direction of the belt conveyor 1. An elastic cloth 7 is wound around the long shaft 6. One end of the elastic cloth 7 is fixed to the long shaft 6, and the other end is fixed to a connecting plate 8. A scraper 3 is set on the lower surface of the elastic cloth 7 and is fixedly connected to the connecting plate 8 and the elastic cloth 7. The elastic cloth 7 extends from both the front and rear ends of the connecting plate 8. Ear seats 9 are fixed to both ends of the connecting plate 8 extending from the elastic cloth 7. A swing rod 10 is hinged to the ear seat 9. The end of the swing rod 10 away from the ear seat 9 is hinged to the mounting plate 5. The long shaft 6 is supported by the mounting frame 4, the elastic cloth 7 is supported by the long shaft 6, and the elastic cloth 7, the elastic cloth 7, the connecting plate 8, and the scraper 3 of the integrated structure are limited by the swing rod 10.
[0038] like Figure 3 and Figure 4 and Figure 5and Figure 6 A power box 11 is fixed on the front side of the mounting frame 4, located above the mounting plate 5. The power box 11 has a hollow interior. One end of the long shaft 6 extends out of the mounting frame 4 and is rotatably connected to the mounting frame 4. The part of the long shaft 6 that extends out of the mounting frame 4 enters the power box 11 and is rotatably connected to the power box 11. The interior of the power box 11 is equipped with a power component that controls the rotation of the long shaft 6. Power is provided by the power component to drive the long shaft 6 to rotate. The rotation of the long shaft 6 will drive the rotation of the scraper 3 to adjust the thickness of the feed on the belt conveyor 1.
[0039] like Figure 3 and Figure 4 and Figure 5 and Figure 6 and Figure 7 The power assembly includes a turbine 12 disposed in the inner cavity of the power box 11 and rotatably connected to the power box 11. The turbine 12 is nested on the outer side of one end of the long shaft 6 entering the power box 11 and is coaxially fixed with the long shaft 6. The inner cavity of the power box 11 is also rotatably connected to a worm gear 13 located beside the turbine 12 and meshing with the turbine 12. The top end of the worm gear 13 extends out of the power box 11 and is rotatably connected to the power box 11. A knob 14 for controlling the rotation of the worm gear 13 is coaxially fixed to the part of the worm gear 13 that extends out of the power box 11. Power is provided by manually rotating the knob 14 to drive the worm gear 13, which is coaxially fixed with the knob 14, to rotate. The rotation of the worm gear 13 will drive the turbine 12, which meshes with the worm gear 13, to rotate. The rotation of the turbine 12 will drive the long shaft 6, which is coaxially fixed with the turbine 12, to rotate.
[0040] When in use, connect the power supply and turn on the switch. The operator pours the feed into the feed hopper 2 through the top opening. The feed poured into the feed hopper 2 will fall onto the first guide plate 15 and be dispersed among the first guide bars 17. Then, it slides along the first guide plate 15 from the high point to the low point. The feed that slides out of the first guide plate 15 will enter the gap between the first guide plate 15 and the feed hopper 2. The feed that enters the gap between the first guide plate 15 and the feed hopper 2 will fall onto the second guide plate 16 and be dispersed among the second guide bars 18. Then, it slides along the second guide plate 16 from the high point to the low point. The feed that slides out of the second guide plate 16 will evenly enter the gap between the second guide plate 16 and the feed hopper 2 and be discharged from the bottom opening of the feed hopper 2, and evenly spread on the belt conveyor 1.
[0041] When the belt conveyor 1 is working, it drives the feed laid on the belt conveyor 1 to move towards the next process. When the feed moves to contact the scraper 3, the scraper 3 scrapes the feed flat, so that the feed will not accumulate on the belt conveyor 1, and prevents a large amount of feed from being poured directly onto the belt conveyor 1, causing feed to overflow.
[0042] When it is necessary to adjust the thickness of the feed spread on the belt conveyor 1, grasp the knob 14 and manually rotate the knob 14. The rotation of the knob 14 will drive the worm gear 13, which is fixed coaxially with the knob 14 and is rotatably connected to the power box 11, to rotate. The rotation of the worm gear 13 will drive the turbine 12, which meshes with the worm gear 13, to rotate. The rotation of the turbine 12 will drive the long shaft 6, which is fixed coaxially with the turbine 12, to rotate. The rotation of the long shaft 6 will cause the elastic cloth 7 on the long shaft 6 to be wound around the long shaft 6 or to extend out of the long shaft 6. The movement of the elastic cloth 7 will drive the connecting plate 8 to move, which in turn will drive the swing arm 10, which is hinged to the connecting plate 8, to rotate, thereby adjusting the position of the scraper 3 and improving the utilization rate of the device.
