Description

Technical Field

[0001] This utility model relates to feeding equipment, specifically a mobile feeding system, and belongs to the technical field of steel raw material processing equipment. Background Technology

[0002] In existing iron and steel metallurgy, the technical and economic indicators of blast furnace ironmaking are closely related to the stability of raw material composition. Production practice shows that a 0.1% reduction in iron-containing raw material grade fluctuations leads to a 0.6%–1.2% reduction in fuel consumption for sintering, a 0.28% increase in sinter production, a 0.3%–0.6% increase in pig iron production, a 0.2%–0.46% reduction in coke ratio, a 0.46% reduction in slag content, and a 0.8% reduction in furnace dust. However, currently, steel plants often use diverse and varied ore raw materials, and due to the unstable composition of ore products, the raw materials often exhibit mixed types, large fluctuations in composition and particle size, resulting in poor raw material composition stability. Iron ore received at ports generally needs to undergo blending operations to improve the stability of raw material composition before smelting, which can effectively improve the technical and economic indicators of blast furnace ironmaking.

[0003] Currently, China's coastal ports have a huge capacity to accept iron ore raw materials, but their main function is the loading, unloading, storage, and shipment of iron ore. In recent years, the blending of ore implemented in some ports has been limited to simple forklift mixing or the use of two stacker-reclaimers to extract two different grades of iron ore from two stockpiles according to the designed hourly flow rate, and then transfer them by belt conveyor to a third stacker-reclaimer to mix the two raw materials in the third stockpile. This mixing method is called coarse blending, which has a limited variety of ore types, poor mixing effect, and uneven composition of the mixture. If the plant does not perform pre-mixing treatment, it will affect the stability of the sinter composition and cause a decline in blast furnace performance. For example, the patent document with publication number CN 108946205 A shows that its system has poor mobility, and the operating range is fixed after the production line is built, resulting in a small operating range and low work efficiency.

[0004] To address the problem of poor mixing of iron ore raw materials in ports, existing technologies have proposed a mobile mixing and batching vehicle (such as patent document CN 118341322 A). This vehicle provides a freely movable, high-efficiency mobile mixing and batching vehicle that integrates weighing and mixing. This device can freely move to different locations to receive materials, then batch and mix different raw materials before discharging. This new batching vehicle reduces the overall size of the batching system, has a simple and reasonable structure, and improves the mobility and applicability of the batching system. It can be widely used in the batching of iron ore raw materials in ports, improving product stability. While this technology can achieve the mixing function of iron ore raw materials in ports, it cannot solve the problem of random mixing and the need to temporarily add raw materials to the mixture. Furthermore, for newly added raw materials with significantly uneven particle size distribution and large fluctuation ranges, existing technologies cannot effectively selectively crush or divert them, which will affect the uniformity of the final mixture. Utility Model Content

[0005] To address the problems of poor mixing effect and low efficiency in existing technologies for temporary random mixing of different raw materials, this invention provides a mobile feeding system. This system, through its modular and mobile structure design, enables rapid temporary mixing of newly added raw materials. Furthermore, to address the issue of low processing efficiency due to large particle size fluctuations in different raw materials, a material transfer mechanism is designed between the feeding hopper and the crushing and mixing mechanism, thereby transferring material from the feeding hopper to the crushing and mixing mechanism. In other words, the feeding hopper can directly discharge fine materials to the conveying mechanism, or coarse materials can be first sent to the crushing and mixing mechanism for fine crushing and mixing before being discharged to the conveying mechanism, thus solving the problem of low mixing efficiency caused by large particle size fluctuations in different raw materials.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A mobile feeding system includes a frame, a feeding hopper, a mixing mechanism, a conveying mechanism, and a traveling mechanism.

[0010] Preferably, the material conveying mechanism includes a head conveyor wheel, a tail conveyor wheel, and a conveyor belt. The head conveyor wheel is mounted above the top feed inlet of the mixing mechanism via a material conveying support frame (the bottom end of the support frame is fixed to the machine frame or to the mixing support). The tail conveyor wheel is mounted on the feeding support frame and located below the hopper. The conveyor belt is rotary and positioned between the head and tail conveyor wheels. A material conveying drive motor is also mounted on the head conveyor wheel. The material conveying mechanism transports the material discharged from the bottom outlet of the hopper to the top feed inlet of the mixing mechanism.

[0011] Preferably, the material conveying head wheel and the material conveying support frame are hinged, and the top of the material conveying support frame extends upward and is hinged to the upper part of the bucket wall on the side of the bucket body closest to the mixing mechanism. A support convex shaft is provided on the lower part of the bucket body. Two support slots are provided on the feeding support frame from top to bottom. The support convex shaft is installed in the upper support slot, and the end of the rotating shaft of the material conveying tail wheel is installed in the lower support slot. The feeding support frame is a telescopic hydraulic support frame, and the height of the bucket body and the end of the material conveying mechanism away from the mixing mechanism can be adjusted by raising and lowering the feeding support frame in the vertical direction.

[0012] Preferably, the mixing mechanism includes a mixing chamber and a mixing roller. The mixing chamber is mounted on the frame via a mixing support, with the top inlet of the mixing chamber located below the discharge end of the conveying mechanism and the bottom outlet of the mixing chamber located above the conveying mechanism. The mixing roller is disposed within the mixing chamber. Preferably, the mixing roller consists of a mixing shaft and several mixing plates disposed on the mixing shaft.

[0013] Preferably, a mixing hood is also provided on top of the mixing chamber. Preferably, the mixing shaft of the mixing roller is connected to the drive shaft of the material conveying mechanism (i.e., the shaft of the material conveying head wheel) via a drive belt.

[0014] Preferably, the conveying mechanism includes a conveying head pulley, a conveying tail pulley, a conveying belt, and a redirecting pulley. The conveying head pulley is mounted on the upper front side of the front end of the frame via a conveying support frame. The conveying tail pulley is mounted on the rear end surface of the frame, and the conveying belt is rotated between the conveying head pulley and the conveying tail pulley. The redirecting pulley is located at the front end of the frame and presses against the surface of the conveying belt (one redirecting pulley is pressed on each side of the conveying belt in the width direction, which will not affect material conveying). In the direction from the conveying tail pulley to the conveying head pulley, the redirecting pulley divides the conveying belt into a horizontal section and an upward section. A conveying drive motor is also provided next to the conveying head pulley.

[0015] Preferably, the bottom end of the material conveying support frame is connected to the front end of the frame via a rotating mechanism, and the top end of the material conveying support frame extends upward at an angle away from the frame. The material conveying head wheel is located at the top end of the material conveying support frame. The material conveying support frame rotates via the rotating mechanism, thereby adjusting the height of the material conveying head wheel.

[0016] Preferably, the rotating mechanism includes a rotating shaft and a rotary motor. The rotating shaft is mounted on the front surface of the frame via a bearing housing, and the rotary motor is located beside the rotating shaft. The bottom end of the material conveying support frame is connected to the rotating shaft (either directly fixed or connected via gear engagement). The rotary motor drives the rotating shaft to rotate, thereby causing the material conveying support frame to rotate with its bottom end as the center of rotation.

[0017] Preferably, the system also includes a mobile trolley, which comprises a frame and pulleys. A slide rail is laid along the length of the frame. The frame is mounted on the slide rail via pulleys and is located between the upper and lower sections of the conveyor belt in a horizontal section.

A second redirecting roller is mounted on the lower rear end of the frame via a second redirecting bracket. A third redirecting roller is mounted on the lower front end of the frame via a third redirecting bracket. The conveyor belt starts from the head pulley, passes sequentially through the redirecting pulley, the tail pulley, the first redirecting roller, the second redirecting roller, and the third redirecting roller, before returning to the head pulley for closure. The third redirecting bracket is a telescopic bracket. Preferably, the first redirecting roller is located between the second and third redirecting rollers, and the vertical heights of both the second and third redirecting rollers are lower than the first redirecting roller, while the vertical height of the first redirecting roller is lower than the lower surface of the frame.

[0018] Preferably, the system also includes a receiving plate, which is disposed on the frame and contacts the lower surface of the conveyor belt above the horizontal section of the conveyor belt.

[0019] Preferably, pulley blocks are provided at both the position of the slide rail in front of the discharge port of the mixing mechanism and the position of the slide rail behind the discharge port of the bypass chute. The pulleys are equipped with their own sliding motors.

[0020] Preferably, the walking mechanism includes walking wheels and wheel frames. Multiple wheel frames are arranged on the lower surface of the frame, and each wheel frame has a walking wheel at its bottom end. A walking drive motor is also mounted on the wheel frame. Preferably, the walking wheels are omnidirectional wheels or one-way wheels.

[0021] Preferably, multiple fixed supports are also provided on the lower surface of the frame, wherein the fixed supports are hand-cranked telescopic supports or hydraulic telescopic supports.

[0022] As a preferred option, a drag head is also provided at the front end of the frame.

[0023] Preferably, a mobile power supply is also provided on the frame, and the mobile power supply is connected to each drive motor through wires.

[0024] As a preferred option, a control box is also installed on the rack to control the start and stop of each component.

[0025] In this utility model, for ease of description, the direction of material flow (i.e., the direction of material flow) is defined according to the direction of material flow on the conveyor belt. Figure 1 The left side is called "front" (including "front end", "front side", "front part", etc.), for example, the drag head is located at the front end of the frame. The direction from which the material flows (i.e., Figure 1 The right side of the frame is called the "rear" (including "rear end", "rear side", "rear part", etc.), for example, the control box is located on the rear surface of the frame.

[0026] In existing technologies, the premixing and batching of port ores faces the challenge of diverse ore raw material sources. Even the same raw material can exhibit significant differences due to its origin, such as large fluctuations in particle size distribution. Furthermore, during the mixing and batching process, there may be a need to temporarily add new raw materials. Existing blending systems generally only handle blending multiple ores with a fixed pattern, making it difficult to cope with the rapid blending of temporarily added raw materials. This invention designs a mobile feeding system with rapid independent movement and rapid material diversion processing capabilities. It can independently achieve rapid preprocessing of temporarily added raw materials, thereby improving the efficiency of rapid blending of these materials with other raw materials. It should be noted that this system can be used alone or in combination with existing technologies (such as CN 118341322 A) to address the complex and fluctuating blending conditions of port raw materials.

[0027] In this invention, the feeding hopper is mounted on the frame and located above the horizontal section of the conveying mechanism. In addition to a bottom discharge port, the feeding hopper also has a bypass discharge port (i.e., discharge gate + bypass chute) on its bottom side wall. The bypass chute extends close to the surface of the horizontal section of the conveying mechanism. In actual operation, when the material particle size is small and does not require crushing, the feeding hopper directly discharges the fine material onto the conveying mechanism via the bypass chute. Both the bottom discharge port and the bypass discharge port of the feeding hopper are equipped with discharge gates with their own drive motors, which control the opening and closing of the bottom discharge port and the bypass discharge port (generally not simultaneously). Simultaneously, the conveying mechanism is a belt conveyor, with its tail end located below the bottom discharge port of the feeding hopper and its head end extending above the inlet of the crushing and mixing mechanism. When the material particle size is large and requires crushing, the conveying mechanism can transport the coarse particles to the crushing and mixing mechanism for crushing and mixing. In other words, by designing a hopper with selective diversion of coarse and fine materials, the coarse and fine materials can be diverted, which helps to improve the mixing efficiency of materials.

[0028] In this invention, the mixing mechanism includes a mixing support, a mixing chamber, a mixing shaft, mixing plates, a mixing cover, and a mixing outlet. The mixing support is mounted on a frame, and the mixing chamber is mounted on the mixing support. The mixing shaft is located in the center of the mixing chamber, and multiple circumferentially distributed mixing plates (the mixing shaft and mixing plates constitute a mixing roller) are fixedly connected to the mixing shaft. The mixing cover is located at the top of the mixing chamber's inlet to prevent dust from being emitted during feeding. The mixing outlet is located at the bottom of the mixing chamber, facing the conveying mechanism, meaning the mixed material is conveyed to the conveying mechanism for transfer. The mixing shaft is connected to a drive motor, or the mixing shaft is connected to the drive shaft of the conveying mechanism via a transmission belt (i.e., the mixing shaft and the conveying mechanism are synchronously driven by the same drive motor). In a preferred embodiment, the mixing plate can be vertical or arc-shaped (made of elastic material), or it can be hammer-shaped (made of wear-resistant material). The choice depends on the properties of the mixed materials. When the material has a small particle size, a vertical shape can be selected, and when the material has a large particle size, an arc shape can be selected. The number of mixing plates is selected according to the amount of material. When the amount of material to be processed is large, the number of mixing plates is increased, and when the amount of material to be processed is small, the number of mixing plates is reduced.

[0029] In this utility model, generally, since coarse particles need to be conveyed to the crushing and mixing mechanism for crushing and mixing, and the crushing and mixing mechanism has a certain height, the conveyor head wheel must be higher than the height of the inlet of the crushing and mixing mechanism. To avoid increasing the overall system height (the higher the system height, the more difficult and inefficient it is to transfer materials stacked at the port to the feeding hopper), the height of the tail pulley is generally no higher than the head pulley. In other words, the lower the tail pulley height, the better. This involves setting the conveyor belt to an inclined structure. However, inclined conveyor belts are designed to have problems with low efficiency, difficulty, or even inability to convey coarse materials (coarse materials tend to roll down the inclined surface). If the tail pulley is set to be the same height as or slightly lower than the head pulley, although this maximizes the balance between not increasing the overall system height and ensuring smooth conveying of coarse materials, the bottom discharge port and bypass discharge port of the feeding hopper are both higher than the tail pulley. Therefore, when the feeding hopper discharges fine materials through the bypass discharge port, the height difference in the bypass chute will be large. The falling fine materials will have a large impact on the conveying mechanism, which can easily cause damage to the conveying mechanism and also cause material splashing. In other words, regardless of whether the material conveying mechanism is designed horizontally or with a higher front and lower rear, it cannot effectively handle both coarse and fine materials smoothly and safely. To address this issue, this invention designs both the hopper and the material conveying mechanism so that the rear section can rotate vertically with the front section as the fulcrum. Thus, when handling coarse materials, the material conveying mechanism is adjusted to a horizontal state and the height of the hopper is increased accordingly; when handling fine materials, the material conveying mechanism is adjusted to a higher front and lower rear state and the height of the hopper is decreased accordingly. Specifically, the material conveying head wheel and the upper part of the front side wall of the feeding hopper are hinged to the upper part and top of the material conveying support frame, respectively (any existing hinge device with a rotating support structure can be selected, such as a combination of a rotating shaft and a bearing). The material conveying tail wheel and the rear side wall of the feeding hopper are connected to the frame through a telescopic feeding support frame (any existing device with telescopic support function can be selected, such as a combination of a hydraulic cylinder and a telescopic rod, with the hydraulic cylinder set on the surface of the frame and the upper end of the telescopic rod connected to the rotating shaft of the material conveying tail wheel and the support convex shaft of the feeding hopper, respectively). That is, the height of the material conveying tail wheel and the feeding hopper can be adjusted by the extension and retraction of the feeding support frame. It should be noted that during the process of adjusting the height of the material conveying tail wheel and the material feeding hopper on the feeding support frame, since the material conveying tail wheel and the material feeding hopper rotate around their respective front hinge points, the shaft of the material conveying tail wheel and the support shaft of the material feeding hopper are connected to the feeding support frame through support slots with transverse through holes. That is, when the feeding support frame is raised or lowered, the shaft of the material conveying tail wheel and the support shaft of the material feeding hopper can slide in the transverse through holes of their respective support slots.Furthermore, the support slot is hinged to the feeding support frame (i.e., the support slot can rotate on its own with the connection point between it and the feeding support frame as the rotation center), which makes it easier to adjust the height of the material conveying tail wheel and the feeding hopper (when adjusted to the target height, the hinged structure of the support slot can be stopped, thereby achieving a further stabilizing effect).

[0030] In this invention, the conveying mechanism is a belt conveyor or chain conveyor. Along the length of the frame, the conveying mechanism is divided into a rear horizontal section and a front ascending section by a redirecting wheel. The material is first fed into the horizontal section and then conveyed to the ascending section (i.e., the bottom discharge port of the mixing mechanism and the discharge port of the bypass chute are both facing the horizontal section of the clinker mechanism). The conveying support frame used to support the ascending section is hinged to the frame through a rotating mechanism (composed of bearing seats and rotating shafts, etc.), so that the tilt angle of the ascending section can be adjusted, thereby realizing the adjustment of the conveying height, so as to facilitate the conveying of materials to receiving devices at different heights. Generally, the angle between the rising segment and the horizontal segment ranges from 0° to 135°, preferably from 10° to 130° (for example, one of 1°, 3°, 5°, 8°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 80°, 75°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, and 135°). This means that the horizontal segment and the rising segment can be folded, which reduces the size of the system when it is not in use and exposes the drag head, making it easier to drag without taking up more parking space (existing technologies such as CN 118341322 A do not have a folding function, resulting in a relatively large space occupation when not in use, which is not conducive to storage and transfer).

[0031] In this invention, it should be noted that although conveyor belts generally have a certain degree of elasticity (unless they are chain plate structures), they are tensioned to support the conveyed materials. This means that when the front ascending section of the conveying mechanism needs to be folded clockwise backward (to reduce space occupation when not in operation and to expose the drag head for easy dragging), the folding angle is limited and will further tension the already tensioned conveyor belt, easily causing irreparable damage. Therefore, this invention provides a movable trolley that can move along the length of the frame between the upper and lower belt sections of the horizontal section of the conveyor belt. The tail wheel is positioned at the rear end of the movable trolley frame (originally at the end away from the head wheel), allowing the tail wheel to move with the movable trolley and adjust its position along the length of the frame. Simultaneously, a first redirecting roller is provided on the lower front side of the frame via a first redirecting bracket, and a second redirecting roller is provided on the lower rear side of the frame via a second redirecting bracket. A third redirecting roller is installed on the lower front side of the frame via a third redirecting bracket. At least one of the first, second, and third redirecting brackets is a telescopic bracket (e.g., composed of a hydraulic cylinder and a telescopic rod, with a redirecting roller at the telescopic end of the rod). The conveyor belt starts from the head pulley, passes sequentially through the redirecting pulley, tail pulley, first redirecting roller, second redirecting roller, and third redirecting roller, before returning to the head pulley for closure. When it is necessary to fold the front ascending section of the conveying mechanism clockwise backward, the downward extension depth of the corresponding redirecting roller can be adjusted by any redirecting bracket (e.g., reducing the downward extension depth of the third redirecting roller via the third redirecting bracket). This de-tensions the conveyor belt, allowing the front ascending section of the conveying mechanism to fold clockwise backward at an angle.

[0032] Furthermore, a receiving plate is installed above the frame of the moving trolley. The receiving plate is in contact with the lower surface of the belt body above the horizontal section of the conveyor belt. The moving trolley can freely move the receiving plate to directly below the discharge port of the crushing mechanism (when processing coarse materials) or to directly below the discharge port of the bypass chute (when processing fine materials). This can be used to support the materials from the feeding hopper and the crushing mechanism, reducing the impact of the materials on the conveyor belt.

[0033] It should be noted that in this utility model, a generator or battery (i.e., a mobile power supply) is also provided on the frame. All the above-mentioned drive motors (including the drive motor of the feeding hopper discharge gate, the drive motor of the mixing mechanism's mixing shaft, the material conveying drive motor, the material transfer drive motor, the drive motor of the receiving plate pulley, the drive motor of the traveling wheel, etc.) are electrically connected to the generator or battery. All the above-mentioned drive motors can be controlled remotely via wired field control or remote control (i.e., control box, preferably a PLC control box).

[0034] Furthermore, a towing head (including a towing bar and towing frame) is installed at the front end of the frame, allowing the entire mobile feeding system to be moved by other vehicles via the towing head. It should be noted that the traveling mechanism's wheels can be all omnidirectional wheels, one-way wheels, or a combination of both. All traveling wheels can be independently equipped with drive motors, or some can be equipped with drive motors, with the remainder serving as driven wheels.

[0035] Furthermore, multiple fixed supports are also installed on the lower surface of the frame. These fixed support mechanisms can be hand-cranked mechanical supports, hydraulic supports (such as a combination of a hydraulic cylinder and a telescopic rod, with a support plate at the retracted end of the telescopic rod to increase the ground contact area), or a combination of both. Fixed supports allow the system to be supported when it does not need to be moved, thereby improving the system's stability and safety.

[0036] In this invention, the length of the frame is 1-30m, preferably 1.5-20m, and more preferably 2-15m. The width of the frame is 1-20m, preferably 1.5-15m, and more preferably 2-10m. The volume of the feeding hopper is 0.5-100m³. 3 Preferably 1~80m 3 More preferably 2~50m 3 .

[0037] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0038] 1. This utility model's feeding system combines crushing and mixing with a diversion-type feeding hopper, enabling separate processing of different materials. This not only allows for selection of whether or not raw materials pass through the crushing device based on their size, significantly improving material processing efficiency and the uniformity of the mixture, but also avoids wear on the crushing device caused by materials that do not require crushing or mixing, further extending the device's lifespan. Furthermore, it can simultaneously receive multiple different raw materials for crushing and mixing, greatly improving the particle size and compositional stability of the mixture.

[0039] 2: The feeding system of this utility model, through the combined design of a rotary lifting hopper and a conveying mechanism, can take into account both the rapid and efficient conveying of coarse materials and the low-impact and safe feeding of fine materials, thereby improving the system's processing efficiency and safety, and also extending the service life of the equipment.

[0040] 3: The feeding system of this utility model significantly enhances the folding capability of the feeding mechanism through the design of the movable receiving plate and the feeding tail wheel, thereby improving the system's ability to quickly and flexibly transfer and store and move low-volume parts. At the same time, it also helps to reduce the risk of damage to the feeding mechanism when receiving materials, and significantly improves the system's mobility and durability.

[0041] 4. The feeding system of this utility model has a simple overall structure and the feeding height of the conveying mechanism is adjustable, which can realize the stacking and transfer of various materials. It is not only suitable for crushing and mixing of port iron raw materials, but also for crushing and mixing of minerals in various fields. It has the advantages of flexible operation range, large operation range, high work efficiency and wide applicability. Attached Figure Description

[0083] Application Examples

[0084] The system described in Example 20 is used to feed ore at a port. The system is moved to the material handling location by the traveling mechanism 5 controlled by the control box 11, or by other vehicles using the towing head 9. The traveling mechanism 5 is then shut down, and the fixed supports 8 are activated, extending to the ground. Multiple fixed supports 8 provide stable support for the frame 1, preventing shaking and instability caused by material impact during processing. The angle of the conveying support frame 405 is then adjusted by the rotating mechanism 406, ensuring the material is thrown from the conveying head wheel 401 to a predetermined height. Then, depending on the material processing requirements, adjust the state of the discharge gate 204 of the feeding hopper 2. If the material to be processed has a good degree of mixing and small particle size, and does not require further crushing and mixing, open the discharge gate 204, shut down the conveying mechanism 6, lower the height of the feeding hopper 2 via the feeding support frame 202, and move the receiving plate 710 along the slide rail 703 via the pulley 702 of the moving trolley 7 to directly below the bottom outlet of the bypass chute 203. Then, use the pulley stop 711 to lock the pulley 702 to prevent the receiving plate 710 from slipping due to material impact. Then, start the conveying mechanism 4 and load material into the feeding hopper 2. The loaded material enters the bypass chute 203 from the discharge gate 204 of the feeding hopper 2, falls onto the conveyor belt 403 through the bypass chute 203, and is then transported to the conveyor head wheel 401 and thrown out, so that the material reaches a certain height. If the material to be processed has poor mixing and large particle size, further crushing and mixing are required. In this case, the discharge gate 204 is closed, and the feeding support frame 202 is used to adjust the conveying mechanism 6 to a horizontal state. The conveying mechanism 6 is then started, and the receiving plate 710 is moved along the slide rail 703 via the pulley 702 to directly below the bottom outlet of the crushing and mixing chamber 301. Then, the pulley 702 is locked by the pulley stop block 711. Then, the crushing and mixing mechanism 3 and the conveying mechanism 4 are started, and material is loaded into the upper hopper 2. The loaded material is conveyed through the conveying mechanism 6 to the crushing and mixing cover 304 of the crushing and mixing mechanism 3, and then enters the crushing and mixing chamber 301 from below. The material is crushed and mixed by the crushing and mixing plate. After crushing and mixing, the material falls from the bottom outlet of the crushing and mixing chamber 301 onto the conveyor belt 403, and is then transported to the conveyor head wheel 401 and thrown out, so that the material reaches a certain height. After material processing, shut down the mixing mechanism 3, conveying mechanism 6, and conveying mechanism 4; retract the fixed support 8; release the brake on the traveling mechanism 5; raise the third redirecting roller 709 via the third redirecting bracket 708 to release the conveying belt 403; rotate the inclined section of the conveying mechanism 4 clockwise towards the horizontal section of the conveying mechanism 4 via the rotating mechanism 406, thereby retracting the inclined section and exposing the towing head 9, allowing it to be moved to other material processing locations or parking points by other vehicles towing the system. Alternatively, the system can be moved to other material processing locations or parking points via remote control of the traveling mechanism 5.
