Description

Technical Field

[0001] This utility model relates to the field of automated breeding equipment technology, and in particular to a residual feed recovery device at the end of a pig farm feed line. Background Technology

[0002] In modern large-scale pig farms, disc feed lines are widely used as a highly efficient automated feed conveying system. Disc feed lines mainly use chains to drive discs to move within the conveying pipeline, thereby conveying feed to the feed troughs in each pig house. This conveying method has the advantages of long conveying distance, high efficiency, and effective prevention of feed grading, which greatly reduces the labor intensity of manual feeding.

[0003] However, after a long period of operation, especially at the turning point at the end of the feed line, residual feed often becomes a problem. Because pig farm feed contains a certain amount of oil or becomes sticky when damp, some fine feed dust and compressed feed clumps will adhere to the chain gaps and disc surfaces of the feed line. Gravity alone cannot make the attached feed fall off naturally. Over time, these residual feeds not only cause unnecessary waste of resources, but more seriously, the feed that has been attached to the feed line for a long time will mold and deteriorate in the humid breeding environment, producing toxins. If this deteriorated feed is transported back into the pigs' feeding process, it will directly threaten the health of the pigs and cause various intestinal diseases or even poisoning.

[0004] Current conventional methods mostly rely on manual periodic disassembly and cleaning or simple external knocking and vibration. Manual cleaning is time-consuming and labor-intensive and difficult to maintain frequently. Simple vibration cleaning is not very effective for stubborn dirt with strong adhesion, and the waste material is often directly scattered on the ground at the end of the material line, which not only causes secondary pollution to the environment, but also increases the burden of subsequent manual cleaning and collection. There is a lack of an effective device that can automatically clean online and simultaneously realize the centralized recycling of waste material.

[0005] Therefore, this utility model proposes a residual material recycling device at the end of a pig farm feed line to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems existing in the pig farm feed line end-of-line residual material recovery device, such as the single cleaning method leading to incomplete removal of sticky feed, the lack of an effective residual material collection structure leading to secondary environmental pollution, and the high cost and low efficiency of manual maintenance and cleaning, this utility model aims to provide a pig farm feed line end-of-line residual material recovery device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a residual material recovery device at the end of a feed line in a pig farm, comprising: a fixed frame, a guide pipe, a mounting frame one, a fan, an air inlet, a mounting frame two, a motor, a scraper disc, a fixed cover, a conveying pipe, and a collection box.

[0008] The fixed frame serves as the main support structure, and the guide tube is fixedly installed on the inner bottom of the fixed frame. The guide tube is used to provide stable support and a guiding path for the feeder disc.

[0009] Furthermore, the first mounting bracket is fixedly connected to one outer wall of the fixed frame, and the fan is fixedly installed inside the first mounting bracket. The side wall of the fixed frame has an air inlet that connects the interior of the first mounting bracket to the internal cavity of the fixed frame. The airflow generated by the fan can be blown to the area above the guide tube through the air inlet. The second mounting bracket is fixedly installed inside the fixed frame. The motor is fixedly installed on the second mounting bracket. The output shaft of the motor is fixedly connected to the scraper disc. The scraper disc is rotatably installed inside the fixed frame and located directly above the guide tube. Multiple flexible blades are fixedly installed on the outer circumferential wall of the scraper disc. Driven by the motor, the scraper disc drives the flexible blades to rotate and perform contact cleaning on the surface of the material line of the stopper disc below. The other outer wall of the fixed frame is fixedly connected to the fixed cover. The fixed cover connects to the interior of the fixed frame. The bottom of the fixed cover is connected to the vertically downward extending conveying pipe. The collection box is set below the conveying pipe, thereby forming a closed-loop residual material collection channel.

[0010] Preferably, the guide tube is located at the bottom left of the scraper disc, and the flexible blades on the scraper disc rotate at an angle to the right of the guide tube, without contacting the guide tube.

[0011] Preferably, the multiple flexible blades are evenly distributed along the circumference of the scraper disc, and the flexible blades are made of rubber material with elasticity and wear resistance. This material selection can ensure the scraping force and adapt to the irregular shape of the material line of the disc by elastic deformation, so as to avoid hard mechanical damage to the conveyor chain or disc.

[0012] Preferably, the axial height of the air inlet is horizontally aligned with the area between the guide tube and the scraper disc, and the air inlet faces the connection port of the fixed cover. This specific positional relationship ensures that the airflow can not only efficiently blow away loose materials, but also help to directionally transport the scraped-off residual materials into the fixed cover.

[0013] Preferably, the second mounting bracket has an inverted U-shaped structure, with both ends of the second mounting bracket fixedly connected to the inner top wall of the fixed frame. The motor is fixedly mounted on the crossbeam of the second mounting bracket by bolts. This suspended structure is stable and leaves sufficient space for the cleaning operation below.

[0014] Preferably, the conveying pipe and the fixing cover are integrally welded, and the inner diameter of the conveying pipe is equal to the opening diameter at the bottom of the fixing cover, ensuring that the residual material falls smoothly without obstruction and preventing accumulation and blockage at the connection.

[0015] Preferably, the collection box is a rectangular box with an opening at the top, and the bottom end of the conveying pipe extends into the opening of the collection box. This non-contact insertion and engagement not only prevents dust from overflowing but also facilitates the independent removal and cleaning of the collection box.

[0016] Preferably, support columns are fixedly connected to the four bottom corners of the fixing frame, and anti-slip bases are fixedly connected to the bottom ends of the support columns. The combination of the support columns and the anti-slip bases improves the overall installation stability of the device and its adaptability to the ground environment.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem that the single cleaning method in the prior art is difficult to effectively remove loose dust and sticky stubborn feed from the surface of the feed line at the same time by setting up a dual cleaning structure that combines side fan blowing and top motor driven flexible blade mechanical scraping. It achieves the effect of thoroughly cleaning the end of the feed line in all directions, effectively preventing feed residue and mold, and reducing feed waste.

[0018] 2. This utility model solves the problem that existing cleaning devices usually directly discharge the leftover material to the ground, causing secondary environmental pollution and making manual collection difficult, by setting a connected fixed cover on the side of the fixed frame, a vertically downward conveying pipe and a collection box at the bottom to construct a closed recycling channel. It achieves the effects of centralized recycling and treatment of leftover material, maintaining the cleanliness of the farm environment and significantly reducing the cost of manual cleaning.

[0019] 3. This utility model, by adopting a design that combines bottom guide tube support for the material line with top flexible material blades for rotating scraping, solves the problems of wear and damage to the material line discs and insufficient cleaning contact caused by vibration of the material line during transmission in existing rigid scraping methods. It achieves the effect of effectively buffering mechanical impact, protecting the integrity of the conveying equipment, and extending the service life of the material line while ensuring efficient material removal.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example:

[0023] Please refer to Figures 1 to 4 This utility model provides a residual feed recovery device at the end of a feed line in a pig farm, which aims to solve the structural defects in the prior art where residual feed at the end of the feed line causes mold and spoilage and feed waste.

[0024] Please refer to Figure 1 and Figure 2A main structure of a pig farm feed tray end-of-line residual feed recovery device includes a fixed frame 1 and a guide tube 11 fixedly installed on the bottom inner side of the fixed frame 1. The fixed frame 1 serves as the external support shell of the entire device, constructing a closed cleaning chamber and providing installation space for internal components. The guide tube 11 allows the feed tray to pass through and supports and guides the moving feed tray, ensuring a stable transmission path within the fixed frame 1 and preventing violent shaking or positional shift of the feed tray during transmission. One side of the outer wall is fixedly connected to the mounting bracket 2 by bolts or welding. The mounting bracket 2 is used to support and protect the power source components. The fan 3 is fixedly installed in the internal space of the mounting bracket 2. The fan 3 is used as an airflow generating device to generate high-speed clean airflow. The side wall of the fixed frame 1 is provided with an air inlet 4. The air inlet 4 connects the internal space of the mounting bracket 2 with the internal cavity of the fixed frame 1. The airflow generated by the fan 3 can be blown directly to the plug disc material line area above the guide tube 11 inside the fixed frame 1 through the air inlet 4, and the air force is used to remove loose adhering materials on the surface of the plug disc material line.

[0025] Please refer to Figure 2 Figure 3 and Figure 4 A mounting bracket 2 8 is fixedly installed in the upper space inside the fixed frame 1. The mounting bracket 2 8 is used to suspend and support the mechanical cleaning components. A motor 9 is fixedly installed on the mounting bracket 2 8. The motor 9 serves as a drive source to provide rotational power. A scraper disc 10 is fixedly connected to the end of the output shaft of the motor 9 via a coupling or key. The scraper disc 10 is rotatably installed inside the fixed frame 1 and is located directly above the guide tube 11. Multiple flexible blades are fixedly installed on the outer circumferential wall of the scraper disc 10. The multiple flexible blades are evenly distributed along the circumference of the scraper disc 10. The scraper disc 10 is used to drive... Flexible blades rotate to perform contact mechanical scraping on the feed line of the lower disc. A fixed cover 5 is fixedly connected to the outer wall of the other side of the fixed frame 1. The internal space of the fixed cover 5 is connected to the internal cavity of the fixed frame 1. The fixed cover 5 is used to receive feed residue that is blown off by wind or mechanically scraped off from the feed line of the disc. A vertically downward extending conveying pipe 6 is connected to the bottom of the fixed cover 5. The conveying pipe 6 is used to guide the residue to fall in a directional direction under the action of gravity. A collection box 7 is movably installed below the conveying pipe 6. The collection box 7 is used to collect the feed residue that finally falls off and clean it manually at regular intervals.

[0026] Please refer to Figure 2 and Figure 4The guide tube 11 is located at the bottom left of the scraper disc 10. The flexible blades on the scraper disc 10 rotate at an angle to the right of the guide tube 11 and do not contact the guide tube 11. When the scraper disc 10 rotates under the drive of the motor 9, the flexible blades periodically sweep across the surface of the feed line on the right side of the guide tube 11. The flexible blades forcibly peel off the stubborn feed adhering to the feed line disc and chain through physical contact and friction. The position of the air inlet 4 is precisely considered. The axis height of the air inlet 4 is horizontally aligned with the gap area between the scraper disc 10 and the guide tube 11, ensuring that the airflow generated by the blower 3 can reach the cleaning area directly through the shortest path. The air inlet 4 faces the entrance of the fixed cover 5, so that while the airflow blows off the loose feed, it can also play a role in pneumatic conveying, assisting in the directional blowing of the feed residue scraped off by the scraper disc 10 and the blown-off dust into the interior of the fixed cover 5, preventing the residue from splashing around inside the fixed frame 1. The stacking and mounting frame 28 adopts a stable inverted U-shaped structure design. The two sides of the mounting frame 28 are fixedly connected to the inner top wall of the fixed frame 1 by bolts or welding. The mounting frame 28 spans the space above the guide tube 11. The motor 9 is fixedly installed at the bottom of the crossbeam of the mounting frame 28 by bolts. This suspended installation structure not only ensures the positioning accuracy of the motor 9 and the scraper disc 10, but also reserves sufficient space for the material line of the lower stop disc to pass through and for airflow. As for the setting of the collection box 7, the collection box 7 is designed as a rectangular box with an open top. The lower end of the conveying pipe 6 extends into the internal space of the collection box 7, and an appropriate gap is maintained between the lower end face of the conveying pipe 6 and the inner bottom wall of the collection box 7. This non-contact insertion and engagement not only prevents the residual material from flying during the fall, but also allows the collection box 7 to be easily pulled out for dumping and cleaning. The collection box 7 is placed movably on the ground or support plane directly below the conveying pipe 6 without the need for additional fixing parts, which facilitates daily maintenance and operation.

[0027] As a preferred embodiment, in order to enhance the cleaning effect and avoid damage to the feed line of the feed disc, the flexible blades are made of rubber material with certain elasticity and wear resistance, such as wear-resistant polyurethane rubber sheet. The rubber material can ensure close contact and scraping with the feed line of the feed disc, while adapting to the irregular surface of the feed disc and chain by its own elastic deformation, avoiding mechanical jamming or breakage of the feed line of the feed disc due to hard contact. Multiple flexible blades are evenly distributed along the circumference of the scraping disc 10, ensuring that the scraping disc 10 can perform multiple continuous scraping operations on the surface of the feed line of the feed disc in one rotation, thereby improving the efficiency of a single cleaning.

[0028] As another preferred embodiment, in order to ensure the stability and sealing of the connection between the conveying pipe 6 and the fixed cover 5, the conveying pipe 6 and the fixed cover 5 adopt an integral welded structure or an integral cast structure, which avoids the problem of material leakage caused by bolt connection. The inner diameter of the conveying pipe 6 is designed to be equal to the opening diameter at the bottom of the fixed cover 5, so as to ensure that the excess material falling from the fixed cover 5 can smoothly enter the conveying pipe 6 and prevent the formation of material accumulation steps at the connection and blockage.

[0029] As another preferred embodiment, in order to improve the stability of the entire device and adapt to the installation requirements of different sites, support columns are welded or bolted to the four corners of the bottom of the fixed frame 1. The support columns are used to raise the fixed frame 1 to a suitable height to adapt to the installation position of the feed line. The bottom end of the support column is fixedly connected to an anti-slip base. The anti-slip base is usually a metal base plate with rubber pads, which can increase the friction with the ground and prevent the device from shifting when the fan 3 and motor 9 vibrate during operation.

[0030] As another preferred embodiment, in order to optimize airflow guidance and prevent turbulence, the air inlet 4 is not a simple opening, but extends inward on the side wall of the fixed frame 1 to form a guide pipe section. The axis of the guide pipe section points to the cleaning area above the guide pipe 11. By directionally guiding the airflow to concentrate on the surface of the feed line of the plug, the disorderly diffusion of airflow inside the fixed frame 1 is reduced, thereby improving the energy utilization rate of the pneumatic material removal.

[0031] Working principle: When the feeder disc material line continuously passes through the internal space of the fixed frame 1 under the drive of the conveying system, the guide tube 11 receives and guides the feeder disc material line to slide stably. The presence of the guide tube 11 effectively limits the up-and-down jumping and left-and-right swing of the feeder disc material line, ensuring that the feeder disc material line to be cleaned is always on the preset cleaning operation center line. Start the fan 3 installed inside the mounting frame 1 2. The strong airflow generated by the high-speed operation of the fan 3 enters the internal cavity of the fixed frame 1 through the air inlet 4. Since the air inlet 4 is directly facing the feed line area of ​​the feed plate, the airflow directly impacts and passes through the feed line and disc surface exposed by the clearance gap above the guide tube 11. The kinetic energy of the high-speed airflow blows away the loose and dry solid feed attached to the feed line surface of the feed plate, completing the first stage of non-contact wind-powered initial cleaning. Then, the motor 9 installed on the mounting frame 2 8 is started. The motor 9 drives the scraper disc 10 below to rotate at high speed. The flexible blades fixed on the outer circumference of the scraper disc 10 rotate accordingly. The high-speed rotating flexible blades repeatedly hit and scrape the surface of the feed line of the feed plate. Through physical and mechanical action, the stubborn feed residue that is sticky and difficult to blow away by wind is strongly peeled off, realizing the second stage of contact deep cleaning. After being swept by wind and scraped by mechanical means, the feed residue is separated from the feed line of the feed plate. Under the combined action of gravity and airflow from the air inlet 4, it is blown towards and falls into the fixed cover 5 connected to the other side of the fixed frame 1. Then the residue slides down the vertically downward conveying pipe 6 and finally collects in the collection box 7 placed at the bottom. This not only achieves thorough cleaning of the feed line of the feed plate, but also completes the centralized recycling of the residue, effectively solving the problems of feed waste and environmental pollution.
