Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to a powder conveyor belt collection device to prevent powder from falling off. Background Technology

[0002] The feed production process typically includes the following key steps:

[0003] Step 1, Raw Material Preparation and Receiving: This is the first step in feed production, involving the collection and preparation of various raw materials required for production. Raw material receiving processes may include the use of conveying equipment, magnetic separators, primary cleaning screens, metering equipment, and silos. Different raw materials, due to their varying physical properties such as flowability and screening capacity, will be cleaned using different primary cleaning screens.

[0004] Step 2, Raw Material Grinding: For some raw materials, such as grains, it may be necessary to grind them to achieve a suitable particle size for production. Grinding processes can be classified into single-stage grinding and double-stage grinding based on the number of grinding cycles.

[0005] Step 3, Ingredient Batching and Mixing: This is a crucial step in ensuring feed formulation and quality. Ingredient batching needs to be precise, and mixing needs to be uniform. The batching scale controls mixing time, mixing door opening time, and includes alarm functions.

[0006] Step 4, Pressing and Shaping: For some types of feed, such as pelleted feed, it may be necessary to press and shape the mixture for easy storage and transportation.

[0007] Step 5: Drying: If the feed contains a high moisture content, it may need to be dried to ensure its stability and extend its shelf life.

[0008] Step 6, Packaging and Storage: The final step is to package the produced feed and store it properly to ensure its quality and safety.

[0009] In the sixth step, a steep-angle belt conveyor is usually used to transport the powdered feed from a lower position to a higher packaging machine for packaging. However, traditional steep-angle belt conveyors transport powdered feed via a rubber conveyor belt. Some of the powdered feed adheres to the rubber conveyor belt and does not enter the packaging machine. When the powdered feed adhering to the rubber conveyor belt moves to the back of the steep-angle belt conveyor, it falls off under gravity. This fallen powdered feed cannot be recycled, resulting in waste and increased production costs. Utility Model Content

[0010] To overcome the shortcomings of existing technologies, this utility model proposes a collection device for preventing powder from falling off a powder conveyor belt. The device includes a steeply inclined belt conveyor for feeding powdered feed into a packaging machine and a frame supporting the conveyor. A guide plate with an inverted U-shaped cross-section is nested outside the steeply inclined belt conveyor and located below its inclined section. The guide plate is inclined, and its top edges on both the front and rear sides extend to the outer wall of the conveyor and are detachably and fixedly connected to it. A collection box for accommodating the powdered feed discharged from the guide plate is placed below the conveyor.

[0011] To achieve the above objectives, a guide plate is used to guide powdered feed adhering to the rubber conveyor belt of the inclined belt conveyor. As the conveyor belt moves to the back, the powdered feed enters the guide plate. Under the action of gravity, the powdered feed falls onto the guide plate. Due to the inclined arrangement of the guide plate, the powdered feed falling onto the guide plate slides down to the right under the action of gravity until it slides out of the guide plate through the opening end on the right side and falls into the collection box next to the guide plate. This facilitates the recycling of powdered feed, reduces costs, lowers energy consumption, and maintains a clean working environment.

[0012] Furthermore, the guide plate is equipped with a cleaning component that cleans the powdered feed adhering to the rubber conveyor belt onto the guide plate.

[0013] The above technical solution, by setting up a cleaning component, ensures that all powdery feed adhering to the rubber conveyor belt falls into the guide plate, improving recycling efficiency and facilitating the cleaning of the rubber conveyor belt.

[0014] Furthermore, the cleaning assembly includes several long shafts evenly arranged on the guide plate. The long shafts are arranged in an array along the long side of the steep-angle belt conveyor. The center line of the long shafts is perpendicular to the long side of the steep-angle belt conveyor. Both ends of the long shafts are rotatably connected to the front and rear sides of the guide plate. The outer circumference of the long shafts is radially integrated with several bristles that contact the rubber conveyor belt. The guide plate is provided with a power assembly for controlling the rotation of the long shafts.

[0015] 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 bristles integrated with the long shaft to rotate. When the bristles rotate, they come into contact with the rubber conveyor belt, cleaning up the powdery feed adhering to the rubber conveyor belt, so that the powdery feed adhering to the rubber conveyor belt falls into the guide plate.

[0016] Furthermore, the front side of the guide plate is integrally equipped with a protective box with a hollow inner cavity. One end of the long shaft extends out of the guide plate, and the other end of the long shaft extends into the protective box and is rotatably connected to the protective box. The power assembly includes a first helical gear that is coaxially fixed to the end of the long shaft that extends into the protective box. Several supports are uniformly fixed to the bottom of the inner cavity of the protective box. A transmission rod that is rotatably connected to the support passes through several supports. A second helical gear that is coaxially nested on the transmission rod and fixedly connected to the transmission rod is also present. Each first helical gear and each second helical gear corresponds to and meshes with each other. A motor that drives the transmission rod to rotate is fixed inside the protective box.

[0017] The above technical solution uses a motor to provide power, which drives the transmission rod to rotate. The power is transmitted through the transmission rod, the first helical gear, and the second helical gear, which drives the long shaft and the brush bristles on the long shaft to rotate, thereby cleaning the rubber conveyor belt.

[0018] Furthermore, the inclined belt conveyor is nested with a water collection box with an inverted U-shaped cross-section located at the bottom of the horizontal section of the inclined belt conveyor. The top of the front and rear sides of the water collection box extends upward and is detachably fixed to the outer side wall of the inclined belt conveyor. The inner cavity of the water collection box is hollow. The water collection box is equipped with a cleaning component for cleaning the rubber conveyor belt of the inclined belt conveyor. The water collection box is equipped with a drain pipe that communicates with the inner cavity of the water collection box and is used to discharge the dirt in the water collection box.

[0019] The above technical solution cleans the rubber conveyor belt that enters the water collection box using a cleaning component. The dirt and wastewater generated during cleaning fall into the water collection box, and the wastewater and dirt in the water collection box are discharged through a drain pipe.

[0020] Furthermore, the cleaning assembly includes a water pump and a cleaning water tank located beside the inclined belt conveyor. The outlet of the cleaning water tank is connected to the inlet of the water pump via a pipeline, and the outlet of the water pump is connected to the inlet of the main drain pipe. The outlet end of the main drain pipe enters the water collection box and is fixedly connected to the water collection box. Several branch drain pipes connected to the main drain pipe are fixed to the part of the main drain pipe entering the water collection box. The end of the branch drain pipe away from the main drain pipe is fixed to the inner wall of the water collection box. Several nozzles for discharging water are fixed to the side of the branch drain pipe facing the rubber conveyor belt.

[0021] The above technical solution uses a water pump to provide power, allowing the cleaning water in the cleaning tank to flow sequentially into the main drain pipe and branch drain pipes, and then spray it out through nozzles to clean the rubber conveyor belt that enters the water collection box.

[0022] Furthermore, a steep-angle belt conveyor extends from the right end of the water collection box. Two slots are provided at the bottom of the groove at one end of the water collection box extending from the steep-angle belt conveyor. Insert blocks are tightly connected in the slots. The insert blocks extend out of the slots. A water baffle is fixed to the part of the insert blocks extending out of the slots. The top of the water baffle extends out of the water collection box and is located next to the rubber conveyor belt.

[0023] Through the above technical solution, the baffle plate is detachably and fixedly connected to the water collection box through slots and inserts. When the steep-angle belt conveyor is working normally, the baffle plate can be removed without affecting the normal operation of the steep-angle belt conveyor. When cleaning the rubber conveyor belt, the baffle plate and the water collection box are tightly connected through slots, and the baffle plate extends out of the water collection box, reducing the possibility of liquid droplets splashing and affecting the working environment when the rubber conveyor belt is running in front.

[0024] In summary, the powder collection device for preventing powder from falling off the conveyor belt has the following beneficial effects:

[0025] (1) The powder conveyor belt anti-powder collection device, through the guide plate, allows the powdered feed attached to the rubber conveyor belt of the inclined belt conveyor to enter the guide plate when the rubber conveyor belt moves to the back. Under the action of gravity, the powdered feed falls on the guide plate. Due to the inclined arrangement of the guide plate, the powdered feed falling on the guide plate slides to the right and down under the action of gravity until it slides out of the guide plate from the right opening end and falls into the collection box next to the guide plate, so as to facilitate the recycling of powdered feed, reduce costs, reduce energy consumption, and maintain the working environment.

[0026] (2) The powder conveyor belt anti-powder collection device is powered by a power component to drive the long shaft to rotate. The rotation of the long shaft will drive the brush integrated with the long shaft to rotate. When the brush rotates, it contacts the rubber conveyor belt and sweeps away the powdery feed adhering to the rubber conveyor belt, so that the powdery feed adhering to the rubber conveyor belt falls into the guide plate.

[0027] (3) The powder conveyor belt anti-powder collection device is powered by a water pump, so that the cleaning water in the cleaning water tank enters the main drain pipe and the branch drain pipe in sequence along the flow direction, and is sprayed out through the nozzle to clean the rubber conveyor belt entering the water collection box. The dirt and sewage generated during cleaning fall into the water collection box, and the sewage and dirt in the water collection box are discharged through the drain pipe.

[0035] 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.

[0036] like Figure 1-5 As shown, the preferred embodiment of this utility model provides a collection device for preventing powder from falling off a powder conveyor belt. It includes a steeply inclined belt conveyor 2 for feeding powdered feed into a packaging machine and a frame 1 supporting the steeply inclined belt conveyor 2. The steeply inclined belt conveyor 2 is existing equipment and will not be described in detail. A guide plate 3 with an inverted U-shaped cross-section is nested outside the steeply inclined belt conveyor 2 and located below the inclined section of the conveyor 2. The guide plate 3 has a hollow inner cavity and openings at both ends. The guide plate 3 is inclined, and its top edges on both the front and rear sides extend to the outer wall of the steeply inclined belt conveyor 2 and are detachably and fixedly connected to it. A collection box 4 for accommodating the powdered feed discharged from the guide plate 3 is placed below the steeply inclined belt conveyor 2.

[0037] like Figure 1 and Figure 2 Through the guide plate 3, the powdered feed attached to the rubber conveyor belt of the inclined belt conveyor 2 enters the guide plate 3 as the rubber conveyor belt moves to the back. Under the action of gravity, the powdered feed falls onto the guide plate 3. Since the guide plate 3 is inclined, the powdered feed falling onto the guide plate 3 slides down to the right under the action of gravity until it slides out of the guide plate 3 through the opening end on the right side of the guide plate 3 and falls into the collection box 4 next to the guide plate 3, so as to facilitate the recycling of powdered feed, reduce costs, reduce energy consumption, and maintain the working environment.

[0038] like Figure 1 and Figure 2 and Figure 3 and Figure 4 In order to further improve the recycling efficiency of powdered feed, the guide plate 3 is equipped with a cleaning component 5 to clean the powdered feed attached to the rubber conveyor belt onto the guide plate 3. By setting the cleaning component 5, the powdered feed attached to the rubber conveyor belt falls into the guide plate 3, which also facilitates the cleaning of the rubber conveyor belt.

[0039] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The cleaning component 5 includes several long shafts 501 evenly arranged on the guide plate 3. The long shafts 501 are arranged in an array along the long side of the inclined belt conveyor 2. The center line of the long shafts 501 is perpendicular to the long side of the inclined belt conveyor 2. Both ends of the long shafts 501 are rotatably connected to the front and rear sides of the guide plate 3. The outer circumference of the long shafts 501 is radially integrated with several bristles 502 that contact the rubber conveyor belt. The guide plate 3 is equipped with a power component that controls the rotation of the long shafts 501. The power component provides power to drive the long shafts 501 to rotate. The rotation of the long shafts 501 will drive the bristles 502 integrated with the long shafts 501 to rotate. When the bristles 502 rotate, they contact the rubber conveyor belt and clean the powdery feed adhering to the rubber conveyor belt, so that the powdery feed adhering to the rubber conveyor belt falls into the guide plate 3.

[0040] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The front side of the guide plate 3 has an integrated protective box 6 with a hollow inner cavity. One end of the long shaft 501 extends out of the guide plate 3 and the other end of the long shaft 501 extends into the protective box 6 and is rotatably connected to the protective box 6. The power component includes a first helical gear 503 that is coaxially fixed to the end of the long shaft 501 that extends into the protective box 6. Several supports 504 are evenly fixed to the bottom of the inner cavity of the protective box 6. A transmission rod 505 rotatably connected to the support 504 passes through the supports 504. A second helical gear 506 is coaxially nested on the transmission rod 505 and fixedly connected to the transmission rod 505. Each first helical gear 503 and each second helical gear 506 correspond to each other and mesh with each other. A motor that drives the transmission rod 505 to rotate is fixed inside the protective box 6.

[0041] like Figure 1 and Figure 2 and Figure 3 and Figure 4Power is provided by a motor, which drives the transmission rod 505 to rotate. The power is transmitted through the transmission rod 505, the first helical gear 503 and the second helical gear 506, which drives the long shaft 501 and the brush bristles 502 on the long shaft 501 to rotate, thereby cleaning the rubber conveyor belt.

[0042] like Figure 1 and Figure 2 and Figure 5 After prolonged use, the rubber conveyor belt needs to be cleaned. Therefore, a water collection box 7 with an inverted U-shaped cross-section is nested outside the steep angle belt conveyor 2 and located at the bottom of the horizontal section of the steep angle belt conveyor 2. The top of the front and rear sides of the water collection box 7 extends upward and is detachably fixed to the outer side wall of the steep angle belt conveyor 2. The inner cavity of the water collection box 7 is hollow. A cleaning component 8 for cleaning the rubber conveyor belt of the steep angle belt conveyor 2 is installed inside the water collection box 7. A drain pipe 9 is provided on the water collection box 7, which communicates with the inner cavity of the water collection box 7 and is used to discharge the dirt inside the water collection box 7.

[0043] like Figure 1 and Figure 2 and Figure 5 The rubber conveyor belt entering the water collection box 7 is cleaned by the cleaning component 8. The dirt and sewage generated during cleaning fall into the water collection box 7 and are discharged through the drain pipe 9.

[0044] like Figure 1 and Figure 2 and Figure 5 The cleaning assembly 8 includes a water pump and a cleaning water tank located beside the inclined belt conveyor 2. The outlet of the cleaning water tank is connected to the inlet of the water pump via a pipeline, and the outlet of the water pump is connected to the inlet of the main drain pipe 9801. The outlet end of the main drain pipe 9801 enters the water collection box 7 and is fixedly connected to the water collection box 7. Several branch drain pipes 9802 connected to the main drain pipe 9801 are fixed to the part of the main drain pipe 9801 that enters the water collection box 7. The end of the branch drain pipe 9802 away from the main drain pipe 9801 is fixed to the inner wall of the water collection box 7. Several nozzles 803 for discharging water are fixed to the side of the branch drain pipe 9802 facing the rubber conveyor belt. Power is provided by the water pump, so that the cleaning water in the cleaning water tank enters the main drain pipe 9801 and the branch drain pipes 9802 in sequence along the flow direction, and is sprayed out through the nozzles 803 to clean the rubber conveyor belt entering the water collection box 7.

[0045] like Figure 1 and Figure 2 and Figure 5The right end of the water collection box 7 extends into the steep-angle conveyor belt 2. Two slots 10 are opened at the bottom of the groove at one end of the water collection box 7 extending into the steep-angle conveyor belt 2. A plug is inserted and connected tightly in the slot 10. The plug extends out of the slot 10. A baffle plate 11 is fixed to the part of the plug extending out of the slot 10. The top of the baffle plate 11 extends out of the water collection box 7 and is located next to the rubber conveyor belt. The baffle plate 11 is detachably fixed to the water collection box 7 through the slots 10 and the plug. When the steep-angle conveyor belt 2 is working normally, the baffle plate 11 can be removed without affecting the normal operation of the steep-angle conveyor belt 2. When cleaning the rubber conveyor belt, the baffle plate 11 is inserted and connected tightly to the water collection box 7 through the slots 10. The baffle plate 11 extends out of the water collection box 7, reducing the possibility of droplets splashing and affecting the working environment when the rubber conveyor belt is running in the front.

[0046] In operation, the power is connected and the switch is turned on. The powdered feed falls onto the front of the horizontal section of the inclined conveyor belt 2. As the rubber conveyor belt of the inclined conveyor belt 2 rotates, the powdered feed moves to the top of the inclined section and is discharged from the top of the inclined conveyor belt 2, falling into the distributor. However, some powdered feed remains attached to the rubber conveyor belt. As the rubber conveyor belt rotates to the back of the inclined section of the inclined conveyor belt 2, the motor is turned on. The motor provides power, driving the transmission shaft, which is coaxially fixed to the motor output shaft, to rotate. The rotation of the transmission shaft drives the second helical gear 506, which is coaxially fixed to the transmission shaft, to rotate. The rotation of the second helical gear 506 then drives... The first helical gear 503, which meshes with the second helical gear 506, rotates. The rotation of the first helical gear 503 will drive the long shaft 501, which is fixed coaxially with the first helical gear 503, to rotate. The rotation of the long shaft 501 will drive the brush bristles 502, which is integrated with the long shaft 501, to rotate. The brush bristles 502 rotate and contact the rubber conveyor belt and clean the rubber conveyor belt, causing the powdered feed attached to the rubber conveyor belt to fall onto the guide plate 3. The guide plate 3 is arranged at an angle. The powdered feed slides out of the guide plate 3 from the opening at the right end of the guide plate 3 and falls into the collection box 4 below the guide plate 3, which makes it convenient for the staff to recycle the powdered feed in the collection box 4 and reduce costs.

[0047] After the device has been used for a period of time, the rubber conveyor belt of the inclined belt conveyor 2 needs to be cleaned. The staff will insert the baffle plate 11 into the water collection box 7 through the slot 10 and the plug, and then turn on the water pump. The water pump will provide power so that the cleaning water in the cleaning water tank will flow into the main drain pipe 9801 and the branch drain pipe 9802 in sequence, and spray it out through the nozzle 803 to clean the rubber conveyor belt that enters the water collection box 7. The dirt and sewage after cleaning will fall into the water collection box and then be discharged through the drain pipe 9, reducing the possibility of dirt and sewage accumulating in the water collection box for a long time.

[0048] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
