Abstract

The application discloses a replenishing device for straw feed, which can be moved to the front of a corresponding roughage bin through cooperation of an air compressor, moving wheels and a track. The rear end of the replenishing hopper is in a hollow shape and is located above the roughage bin. A chain is installed in the replenishing hopper through a driving shaft and a compression roller. A plurality of scrapers are installed on the chain and are in contact with the bottom of the replenishing hopper. After roughage in a material transport vehicle is discharged into the replenishing hopper through a discharge port, the roughage is replenished into the roughage bin through the scrapers. The cooperation of the scrapers and the replenishing hopper can make the roughage in the roughage bin be sequentially replenished from the rear end to the front end, and can avoid the roughage from falling on a channel, thereby avoiding waste of the roughage and environmental pollution. Meanwhile, cooperation of a dust hood, a dust remover and a fan can effectively reduce dust during the replenishing operation, and further avoid pollution to the environment. In addition, a control system provided by the application has the above effects.

Description

Technical Field

[0001] This invention relates to the field of roughage replenishment and batching technology, and in particular to a straw feed replenishment device and its control system. Background Technology

[0002] Due to the high demand for roughage on farms, replenishment of roughage is necessary between batches. Based on the farm's scale and calculated batching frequency and timing, 20 roughage silos (50m³ each) should be configured, divided into two groups of 10 silos for every 4 TMR (Total Mixed Ration) machines. This ensures that the roughage silos are always ready when the total mixed ration (TMR) mixer or other batching equipment begins the next batch, preventing production line interruptions due to shortages. However, placing the roughage silos side-by-side and using large machinery for replenishment involves long transport distances, small batch sizes, and the risk of feed spillage onto the aisles, leading to waste, environmental pollution, and significant dust generation during replenishment, further contributing to environmental pollution. Summary of the Invention

[0003] The purpose of this application is to provide a straw feed replenishment device and its control system to solve the problems of long conveying distances, small conveying volumes, easy spillage of feed on the passage, waste of feed and environmental pollution, and large dust emissions during replenishment operations, which further contribute to environmental pollution when using large engineering machinery for replenishment.

[0004] To solve the above-mentioned technical problems, this application provides a straw feed replenishment device, comprising: The feed hopper includes a feed delivery vehicle located at the front end of the feed hopper and a track set in front of the parallel coarse feed bins; the feed delivery vehicle is equipped with a spiral auger and has a discharge port at its rear bottom corresponding to the feed hopper. The replenishment hopper has rollers installed at its front bottom. An air compressor is mounted on the bottom side of the replenishment hopper via a mounting frame. The bottom of the mounting frame is equipped with movable wheels that cooperate with the track via a connecting frame. The rear part of the replenishment hopper above the coarse feed bin is hollow. A chain is installed inside the replenishment hopper via a drive shaft and pressure rollers. Multiple scrapers are installed on the chain that contact the bottom of the replenishment hopper. Dust hoods are installed on both sides of the replenishment hopper. A dust collector is installed on the top of the dust hood. A fan is installed on one side of the dust collector, and the other side is connected to the dust hood via a dust collection pipe.

[0005] In a preferred embodiment, a straw feed replenishment device is provided, wherein the replenishment hopper includes a high-level horizontal section, an inclined section, and a low-level horizontal section. The high-level horizontal section is located above the roughage hopper and has a hollow bottom. The air compressor is located on the bottom side of the inclined section. The discharge port at the rear end of the replenishment hopper is located above the low-level horizontal section. The roller is installed at the bottom front end of the low-level horizontal section. The pressure roller is installed at the connection between the high horizontal section and the inclined section, and between the inclined section and the low horizontal section.

[0006] The solution requires detailed explanation of a straw feed replenishment device, wherein the dust hood extends above the rear end of the transport vehicle.

[0007] In a preferred embodiment, a straw feed replenishment device is provided, wherein each of the scrapers is arranged at an angle.

[0008] The solution requires further detailed explanation of a straw feed replenishment device, wherein the dust removal hood is a transparent cover.

[0009] To solve the above-mentioned technical problems, this application also provides a control system for a replenishment device, based on the straw feed replenishment device described in any one of the above claims, comprising: The system includes a central controller, an coded cable laid on the track, and a reading head installed on the bottom side of the mounting frame. The reading head is matched and corresponds to the coded cable, and the central controller is communicatively connected to the reading head. The central controller is used to control the movement of the replenishment hopper according to the user input command until it is determined that the code fed back by the reading head is consistent with the bin number corresponding to the input command. Then, it controls the replenishment hopper to stop moving and controls the chain to drive the scraper to replenish the current roughage bin. The central controller stores a code and warehouse number lookup table.

[0010] If not, return the encoding of the encoded cable that received the feedback from the read head.

[0011] Compared with the prior art, the present invention provides a straw feed replenishment device, including a replenishment hopper, a transport vehicle located at the front end of the replenishment hopper, and a track set in front of the parallel-arranged roughage bins; the transport vehicle is equipped with a spiral auger and has a discharge port at its rear bottom corresponding to the replenishment hopper; an air compressor is mounted on the bottom side of the replenishment hopper via a mounting frame, and the bottom of the mounting frame is equipped with casters that cooperate with the track via a connecting frame. In use, the replenishment device can be moved to the corresponding roughage bin by the cooperation of the air compressor and the casters. The replenishment hopper, located at the rear end above the roughage silo, is hollowed out. A chain is installed inside the hopper via a drive shaft and pressure rollers. Multiple scrapers are mounted on the chain, contacting the bottom of the hopper. Controlling the auger and chain movement allows feed from the transport vehicle to be discharged into the replenishment hopper through the discharge port. The scrapers then replenish the roughage silo. This coordinated arrangement of the scrapers and hopper ensures the roughage silo is filled sequentially from rear to front, preventing feed from falling into the channel and causing waste and environmental pollution. Dust hoods are installed on both sides of the replenishment hopper, with dust collectors on top. One side of the dust collector has a fan, and the other side is connected to the dust hood via a dust collection pipe. The combined use of the dust hoods, dust collectors, and fans effectively reduces dust during replenishment operations, further preventing environmental pollution. Furthermore, the control system for the replenishment device provided in this application achieves the same effects as described above. Attached Figure Description

[0014] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0015] The core of this application is to provide a straw feed replenishment device and its control system, which solves the problems of long conveying distances, small conveying volumes, easy spillage of feed on the passage, waste of feed and environmental pollution, and large dust emissions during replenishment operations, which further cause environmental pollution when using large engineering machinery for replenishment.

Figure 2 This is a schematic diagram of a replenishment hopper structure provided in an embodiment of this application. Figure 3 This is a schematic diagram of the location structure of a replenishment hopper and a material transport vehicle provided in an embodiment of this application. Figure 4 This is a schematic diagram of the location structure of another replenishment hopper and material transport vehicle provided in an embodiment of this application. Figure 5 A schematic diagram of a control system structure for a replenishment device provided in an embodiment of this application is shown below. Figures 1 to 5 As shown.

[0017] Example 1 A straw feed replenishment device includes a replenishment hopper 1, a feed cart 2 located at the front end of the replenishment hopper 1, and a track 4 set in front of the coarse feed bins 3 arranged side by side. A spiral auger 5 is installed in the feed cart 2, and a discharge port 50 corresponding to the replenishment hopper 1 is set at the bottom of its rear end. When replenishing, the rear end of the feed cart 2 is located above the front end of the replenishment hopper 1. The feed in the feed cart 2 can be transported to the discharge port 50 through the spiral auger 5 and finally discharged into the replenishment hopper 1. The front end A of the replenishment hopper 1 is inclined to ensure that the feed discharged through the discharge port 50 falls smoothly into the replenishment hopper 1.

[0018] The front bottom of the replenishment hopper 1 is equipped with rollers 01, which support the front end of the replenishment hopper 1 and ensure the stability of its movement. An air compressor 7 is mounted on the bottom side of the replenishment hopper 1 via a mounting frame 6. The bottom of the mounting frame 6 is equipped with moving wheels 9 that cooperate with the track 4 via a connecting frame 8. The air compressor 7 provides power to move the moving wheels 9 along the track 4. The rear part B of the replenishment hopper 1, located above the coarse feed bin 3, is hollow. A chain 12 is installed inside the replenishment hopper 1 via a drive shaft 10 and a pressure roller 11. The drive shaft 10 is driven by a motor installed on the outside of the replenishment hopper 1 (not shown in the figure). Multiple scrapers 13 are installed on the chain 12, which contact the bottom of the replenishment hopper 1. The feed falling into the replenishment hopper 1 is conveyed by the scrapers 13 to the hollowed-out area at the rear end of the replenishment hopper 1 as the chain 12 moves. Finally, the feed falls into the replenishment hopper 1 from the hollowed-out area. Figure 2 The arrows shown indicate the direction of rotation of chain 12. When using this replenishment hopper 1 for feed replenishment, the feed is first filled from the tail end of the roughage bin 3. When the feed in the tail end of the roughage bin 3 is level with the perforated discharge port of the replenishment hopper 1, the feed will be transported to the front end of the roughage bin 3 along the conveying direction of the scraper 13. This allows for the addition of feed to a large area within the roughage bin 3, improving the replenishment coverage rate. This replenishment device reduces the conveying distance of straw feed, allowing for replenishment while unloading, resulting in high replenishment efficiency.

[0019] Dust hoods 14 are installed on both sides of the replenishment hopper 1, completely covering the hopper 1. A dust collector 15 is installed on the top of the dust hoods 14. The dust collector 15 is a pulse-jet dust collector. A fan 16 is installed on one side of the dust collector 15, and the other side is connected to the dust hood 14 through a dust collection pipe 17. During the replenishment process, the fan 16 creates a negative pressure inside the dust hood 14, drawing the dust generated during the replenishment process into the pulse-jet dust collector. The dust filtration device inside the pulse-jet dust collector separates the dust from the air, and the collected dust is shaken into the coarse feed bin 3 by pulse vibration, preventing dust from escaping and causing environmental pollution and feed waste.

[0020] Example 2 Based on the embodiments, a straw feed replenishment device is provided. The replenishment hopper 1 includes a high-level horizontal section 18, an inclined section 19, and a low-level horizontal section 20. The high-level horizontal section 18 is located above the roughage bin 3 and has a hollow bottom. An air compressor 7 is located on the bottom side of the inclined section 19. The discharge port 50 at the rear end of the replenishment hopper 1 is located above the low-level horizontal section 20. A roller 01 is installed at the front bottom of the low-level horizontal section 20. The replenishment hopper 1 has a Z-shaped structure, and the low-level horizontal section 20 is close to the ground. The transport vehicle 2 can unload material above the low-level horizontal section 20. The conveying method uses a chain 12 to drive a scraper 13, which scrapes the material in the replenishment hopper 1, lifts it, and transports it to the roughage bin 3.

[0021] The pressure roller 11 is installed at the connection between the high horizontal section 18 and the inclined section 19, and between the inclined section 19 and the low horizontal section 20. The pressure roller 11 presses and limits the chain 12 to ensure that the chain 12 runs along the set path.

[0022] Based on Example 1, in order to improve dust removal efficiency, a straw feed replenishment device can preferably extend the dust removal hood 14 to the rear end of the feed truck 2.

[0023] Based on Example 1, a straw feed replenishment device is provided, and in order to ensure the feed conveying effect and efficiency, each scraper 13 can preferably be set at an angle.

[0024] Based on Example 1, in order to facilitate the observation of the material conveying situation in the replenishment hopper 1, the dust cover 14 of a straw feed replenishment device can preferably be set as a transparent cover.

[0025] The present invention provides a straw feed replenishment device, comprising a replenishment hopper 1, a conveyor 2 located at the front end of the replenishment hopper 1, and a track 4 set in front of the parallel-arranged roughage bins 3; the conveyor 2 is equipped with a spiral auger 5 and has a discharge port 50 corresponding to the replenishment hopper 1 at its rear bottom; an air compressor 7 is mounted on the bottom side of the replenishment hopper 1 via a mounting frame 6, and the bottom of the mounting frame 6 is equipped with movable wheels 9 that cooperate with the track 4 via a connecting frame 8. In use, the replenishment device can be moved to the front of the corresponding roughage bin 3 by the cooperation of the air compressor 7, the movable wheels 9, and the rollers 01; the replenishment hopper The rear section above the roughage bin 3 is hollow. A chain 12 is installed inside the replenishment hopper 1 via a drive shaft 10 and a pressure roller 11. Multiple scrapers 13 are installed on the chain 12 and contact the bottom of the replenishment hopper 1. The operation of the auger 5 and the chain 12 is controlled so that the feed in the transport vehicle 2 is lowered into the replenishment hopper 1 through the discharge port 50. The scrapers 13 then replenish the roughage bin 3. The coordinated arrangement of the scrapers 13 and the replenishment hopper 1 allows the feed in the roughage bin 3 to be replenished sequentially from the rear to the front, and it can prevent the feed from falling onto the channel, causing feed waste and environmental pollution. Dust hoods 14 are installed on both sides of the replenishment hopper 1. A dust collector 15 is installed on the top of the dust hood 14. A fan 16 is installed on one side of the dust collector 15 and the other side is connected to the dust hood 14 through a dust removal pipe 17. At the same time, the combined use of the dust hood 14, the dust collector 15 and the fan 16 can effectively reduce dust during replenishment operations and further avoid environmental pollution.

[0026] Example 3 The foregoing has described in detail an embodiment of a straw feed replenishment device. Based on the straw feed replenishment device described in the above embodiment, this invention also provides a control system for the replenishment device corresponding to the device. Since the embodiments of the system part correspond to the embodiments of the device part, please refer to the description of the embodiments of the device part for the embodiments of the system part, and will not be repeated here.

[0027] A control system for a replenishment device, based on a straw feed replenishment device provided in any of the above embodiments, includes: The system includes a central controller 21, an coded cable 22 laid on the track 4, and a reading head 23 installed on the bottom side of the mounting frame 6. The reading head 23 is matched and corresponds to the coded cable 22, and the central controller 21 is communicatively connected to the reading head 23. The central controller 21 is used to control the movement of the replenishment hopper 1 according to the user input command until it is determined that the code fed back by the reading head 23 is consistent with the bin number corresponding to the input command. Then, it controls the replenishment hopper 1 to stop moving and controls the chain 12 to drive the scraper 13 to replenish the current coarse feed bin 3. The central controller 21 stores a code-bin number lookup table. During actual operation, each roughage bin 3 is marked with a bin number, and the corresponding code is printed on the coding cable 22. The code on the coding cable 22 for each roughage bin 3 is fixed. The reading head 23 can be a PEPPERL+FUCHS model.

[0028] The specific control methods are as follows: Receive user input commands; The replenishment hopper 1 is moved according to the input command, and the encoding of the encoding cable 22 is received from the reading head 23. Determine whether the bin number and code corresponding to the input command are consistent; if they are, control the chain 12 to drive the scraper 13 to replenish the current coarse feed bin 3; proceed to step S104; if not, return to the encoding step of the encoding cable 22 that receives feedback from the reading head 23.

[0029] In other words, the reading head 23 reads the code on the coded cable 22 in real time. The central controller 21 (PLC) stores a code-to-warehouse-number lookup table (e.g., code 12500 corresponds to the center point of warehouse 3). When the central controller 21 commands the trolley to move to warehouse 3, it calculates the target code position (12500) and directs the trolley to move until the code fed back by the reading head 23 matches code 12500, at which point it stops moving. Of course, this control method can be implemented using existing programs and is not an improvement of this invention.

[0030] The present invention provides a control system for a replenishment device, which can realize the automatic correspondence between the replenishment device and the roughage bin 3, improve the degree of automation, reduce labor costs, and improve replenishment efficiency.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and incorporate common knowledge or customary techniques in the art disclosed herein.
