Description

Technical Field

[0001] This invention relates to the field of conveying and stacking devices, and more specifically, to a hopper-type tracked mobile stacker. Background Technology

[0002] Currently, in ports, docks, storage yards, and mines, the commonly used bulk material mobile conveying equipment is usually a tracked mobile stacker to complete the mobile feeding and stacking of materials. In order to meet the feeding needs of non-continuous feeding equipment such as forklifts, some stacking equipment is equipped with a guide chute or simple receiving hopper at the rear. During operation, the forklift dumps the material into the guide chute or hopper, and the material slides down the guide chute onto the stacker belt conveyor, and is then transported to the designated location for stacking. Due to its certain mobility, this type of equipment is widely used in short-distance transportation and temporary stacking scenarios.

[0003] However, when the equipment is used to transport highly viscous and moist materials such as wet clay, the forklift dumps several tons of material into the hopper at a time. The enormous impact pressure generated by the vertical fall of the material acts directly on the bottom of the hopper and the discharge area. Because wet clay is easily compacted and caking under pressure, the material arches or blocks in the hopper, sometimes even completely stopping the feeding process, requiring manual intervention and severely impacting operational efficiency. Secondly, most existing hoppers are simple open structures, lacking active guidance for material flow. The material often forms a high-pressure column in the center of the hopper, causing excessive load on the bottom feeding conveyor belt and uneven material distribution, further exacerbating the risk of blockage.

[0004] Furthermore, the hoppers of existing mobile stackers are usually fixed structures, lacking the ability to adapt to the characteristics of materials. For materials with different moisture content and viscosity, parameters such as the discharge port size and guide angle of the hopper cannot be adjusted according to the actual situation, resulting in unstable performance of the equipment when dealing with diverse materials. Especially when handling materials with high moisture content, the material is prone to sticking to the inner wall of the hopper and agglomerating, which can lead to secondary blockages, increasing the frequency of equipment maintenance and operating costs. At the same time, the hoppers of existing equipment mostly adopt a single-layer structure, lacking effective buffering and vibration reduction design. Long-term exposure to the impact of unloading by the forklift can easily cause cracking of the hopper welds and structural deformation, affecting the service life of the equipment and operational safety. Summary of the Invention

[0005] This invention provides a hopper-type tracked mobile stacker, which solves the technical problems in related technologies where the hopper of a mobile stacker is affected by the impact of discontinuous feeding, resulting in poor material discharge stability and insufficient adaptability to different materials.

[0006] The present invention provides a hopper-type tracked mobile stacker, including a running mechanism, on which a stacker belt conveyor, a hopper and a feeding belt conveyor are installed. One end of the stacker belt conveyor is fixedly connected to the feeding belt conveyor, and the feeding belt conveyor is installed and connected to the bottom of the hopper.

[0007] In a preferred embodiment, the running mechanism includes tracks, a power pack, a chassis, a frame mounting bracket, and a pitch module. The tracks are driven by the power pack and mounted on the chassis. The top of the chassis is fixedly connected to the power pack.

The frame mounting bracket is fixedly connected to the tail frame, and the other end of the pitch module is fixedly connected to the folding module.

[0008] In a preferred embodiment, the hopper is fixedly connected to the top of the chassis on one side near the tail section.

[0009] In a preferred embodiment, the hopper includes an outer hopper body, a discharge pipe, and an inner hopper body. The bottom of the outer hopper body is fixedly connected to the top of the chassis, and the interior of the outer hopper body is connected to the inner hopper body. An installation hole is provided at the bottom of the outer hopper body, the top of the installation hole is connected to the bottom opening of the inner hopper body, and the installation hole communicates with the interior of the inner hopper body. The bottom of the installation hole is fixedly connected to the top of the discharge pipe, and an electromagnetic valve for opening and closing the outer hopper body is provided inside the discharge pipe.

[0010] In a preferred embodiment, there is a cavity between the inner wall of the outer hopper and the outer wall of the inner hopper, and a vibration motor is fixedly installed inside the cavity, with the output end of the vibration motor fixedly connected to the outer wall of the inner hopper.

[0011] In a preferred embodiment, a flow guiding module is provided inside the outer bucket body. The flow guiding module is located at the center of the top opening of the outer bucket body, and the cone-shaped baffle is set with the cone apex facing upward. The flow guiding module includes a telescopic rod and a cone-shaped baffle. The top side of the cone-shaped baffle is fixedly connected to one end of the telescopic rod. The cone-shaped baffle is pyramidal, and buffer strips are fixedly connected to the side of the cone-shaped baffle from top to bottom.

[0012] In a preferred embodiment, a buffer module is provided on the inner wall of the outer bucket. The buffer module includes a first slider, a lead screw, a second slider, a connecting rod, and a mounting bracket. There are two mounting brackets, which are fixedly connected to the inner walls of opposite sides of the outer bucket. The surface of the mounting bracket is provided with a mounting groove. The lead screw and the connecting rod are respectively set in the mounting grooves opened inside the two mounting brackets. One end of the lead screw is rotatably connected to the bottom of the mounting groove. The first slider is threadedly connected to the circumferential side of the lead screw. The first slider is slidably connected along the axial direction of the lead screw. The side of the first slider is fixedly connected to one end of the telescopic rod.

[0013] In a preferred embodiment, both the upper and lower ends of the connecting rod are fixedly connected to the upper and lower sides of the inner wall of the mounting groove. A second slider is installed on the circumferential side of the connecting rod. The second slider slides up and down along the axial direction of the connecting rod. The side of the second slider is fixedly connected to one end of the telescopic rod.

[0014] In a preferred embodiment, the tip of the lead screw penetrates the inner wall of the mounting groove to the top of the mounting frame, and the tip of the lead screw is fixedly connected to the motor output end, and the motor is fixedly connected to the top of the mounting frame.

[0015] In a preferred embodiment, the feeding belt conveyor is located below the discharge pipe, and the discharge end of the feeding belt conveyor is connected to the feed end of the tail frame.

[0016] The beneficial effects of this invention are as follows: This invention transforms the vertical impact of a loader unloading material into sliding along the cone surface in all directions by setting a cone-shaped baffle with the cone tip facing upward at the center of the top of the hopper. This avoids the material directly impacting the bottom of the hopper and forming a high-pressure zone, making it particularly suitable for highly viscous materials such as wet clay. It significantly reduces the risk of blockage caused by compaction and caking. This structural design effectively improves the flow state of the material in the hopper, avoiding the phenomenon of material accumulation in the center and voids around the perimeter in traditional hoppers, thereby improving the uniformity of material flow.

[0017] This invention further slows down the material's descent speed by incorporating multiple layers of buffer strips on the side of the conical baffle, preventing material splashing and guiding the material to flow evenly towards the annular area on the inner wall of the hopper. This reduces impact and wear on the inner hopper body, extending the hopper's service life. The arrangement of the buffer strips, in conjunction with the geometry of the conical baffle, enables graded deceleration of the material during its descent, reducing the instantaneous pressure on the bottom outlet.

[0018] This invention integrates a hopper, a feeding conveyor belt, and a stacker conveyor belt onto a tracked running mechanism, enabling self-movement without additional traction. The stacker conveyor belt is equipped with a folding module, which can be quickly folded and shortened during relocation or transportation, reducing transportation space and improving equipment mobility. This integrated design allows the equipment to maintain good passability and adaptability in complex environments, making it particularly suitable for working conditions where work locations are frequently changed.

[0019] This invention achieves precise adjustment of the height of the conical baffle by setting up a liftable flow guiding module and combining it with the screw drive mechanism in the buffer module. This optimizes the flow guiding effect according to the flow characteristics of different materials. For high-humidity and viscous materials, the baffle height can be reduced to shorten the slippage path and prevent secondary adhesion. For materials with good flowability, the baffle can be raised to improve the feeding efficiency, thereby enhancing the versatility and adaptability of the equipment.

[0020] This invention achieves both pitch adjustment and folding function of the stacker conveyor through the coordinated operation of the pitch module and folding module, enabling the equipment to quickly switch between stacking height adjustment and transportation status transformation, thereby improving the overall performance and operational flexibility of the equipment.

[0021] This invention forms a stable support structure by fixing the frame to the tail frame and connecting the pitching module to the folding module, thus ensuring the structural rigidity and operational stability of the stacker conveyor in operation and avoiding swaying or shaking caused by vibration or load changes.

[0022] This invention utilizes a vibrating motor installed inside the hopper, with its output end fixedly connected to the outer wall of the inner hopper. When material adheres to the wall or arches, high-frequency vibration breaks the adhesion between the material and the inner wall of the hopper, causing the material to flow and fall again, avoiding downtime for cleaning due to material blockage and significantly improving operational continuity and efficiency. An electromagnetic valve inside the discharge pipe, combined with the lifting and lowering adjustment of the flow guide module, controls the opening and closing of the hopper discharge port, facilitating equipment shutdown for maintenance or emergency material supply cut-off, improving operational safety and maintenance convenience. By placing the feeding belt conveyor below the discharge pipe and connecting its discharge end to the inlet end of the tail frame, a continuous material conveying path is formed, preventing spillage or dust during material transfer, improving the working environment, and reducing material loss.

Detailed Implementation

[0031] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the hopper-type tracked mobile stacker includes a running mechanism 1, on which a stacker belt conveyor 2, a hopper 3, and a feeding belt conveyor 4 are installed. One end of the stacker belt conveyor 2 is fixedly connected to the feeding belt conveyor 4, and the feeding belt conveyor 4 is installed and connected to the bottom of the hopper 3. The stacker conveyor 2 includes a head frame 201, a middle frame 202, a tail frame 203, and a folding module 204. One end of the head frame 201 is fixedly connected to one end of the folding module 204, the other end of the folding module 204 is fixedly connected to one end of the middle frame 202, and the other end of the middle frame 202 is hinged to the tail frame 203.

[0033] The running mechanism 1 includes tracks 101, a power pack 102, a chassis 103, a frame fixing frame 104, and a pitch module 105. The tracks 101 are driven by the power pack 102 and mounted on the chassis 103. The top of the chassis 103 is fixedly connected to the power pack 102. One end of the top of the chassis 103 is fixedly connected to the frame fixing frame 104. The other end of the top of the chassis 103 is hinged to one end of the pitch module 105. The frame fixing frame 104 is fixedly connected to the tail frame 203. The other end of the pitch module 105 is fixedly connected to the folding module 204.

[0034] It should be further explained that the running mechanism 1 serves as the mobile load-bearing foundation of the entire machine. The tracks 101 are driven by the power pack 102, providing mobility for the equipment and adapting to complex sites such as stockyards and docks. The chassis 103 serves as the load-bearing platform for installing and securing other functional components. The power pack 102 can integrate a diesel generator set or an external power interface to provide hydraulic power and electrical support for the entire machine. The stacker conveyor 2 is the material conveying and stacking execution component. The tail frame 203 connects to the discharge end of the feeding conveyor 4 to receive materials. The middle frame 202 and the head frame 201 serve as material conveying channels. The folding module 204 is driven by a hydraulic cylinder, enabling the stacker conveyor 2 to achieve [the desired stacking height]. The folding or unfolding mechanism facilitates the reduction of the overall size of the equipment during relocation or transportation. The hopper 3 is installed on the top of the chassis 103 near the tail frame 203 to receive materials dumped by non-continuous feeding equipment such as forklifts and to serve as a temporary storage container. A feeding conveyor belt 4 is installed at its bottom to continuously and evenly transport the material in the hopper 3 to the stacker conveyor 2. Through the extension and retraction of the pitch module 105, the stacker conveyor 2 can be driven to pitch and swing around its hinge point with the tail frame 203, thereby adjusting the height of the head of the stacker conveyor 2 to adapt to the height of different transport vehicles or different stacking height requirements. The frame fixing frame 104 is used to support and position the tail of the stacker conveyor 2.

[0035] In this invention, when the equipment is in operation, the entire machine is first moved to the designated working position by the track 101 of the running mechanism 1. According to the on-site working conditions, the pitch module 105 drives the stacker conveyor 2 to adjust the pitch so that the discharge end of the head frame 201 reaches the required stacking height or the height matching the transport vehicle. Subsequently, the loading equipment such as the loader pours the material into the hopper 3, which temporarily stores the material. The feeding conveyor 4 located at the bottom of the hopper 3 starts to continuously and evenly transport the material in the hopper 3 backward and into the tail frame 2 that is connected to it. 03. At the feeding end, after the material enters the stacker conveyor 2, it is sequentially conveyed to the discharge end via the tail frame 203, the middle frame 202, and the head frame 201, and finally falls into the stockpile or transport vehicle to complete the stacking or loading operation. When the equipment needs to be moved or transported over long distances, the middle frame 202 and the head frame 201 of the stacker conveyor 2 can be folded relative to each other by operating the folding module 204, so that the overall length of the machine is shortened and the transportation space is reduced. At the same time, the stacker conveyor 2 can be lowered as a whole by the tilting module 105 to further reduce the overall height of the machine and improve the transportation passability.

[0036] The hopper 3 is fixedly connected to the top of the chassis 103 on one side near the tail frame 203; this allows the material to enter the feeding conveyor belt 4 via the shortest path after being discharged from the hopper 3, and then be conveyed to the stacker conveyor belt 2. This arrangement effectively reduces the transfer distance of the material during the conveying process, reduces energy consumption and equipment space occupation. At the same time, the position of the hopper 3 balances the center of gravity distribution of the overall device, ensuring the stability of the equipment in the walking and working state.

[0037] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the hopper 3 includes an outer hopper body 31, a discharge pipe 32, and an inner hopper body 34. The bottom of the outer hopper body 31 is fixedly connected to the top of the chassis 103, and the interior of the outer hopper body 31 is connected to the inner hopper body 34. An installation hole is provided at the bottom of the outer hopper body 31, and the top of the installation hole is connected to the bottom opening of the inner hopper body 34. The installation hole communicates with the interior of the inner hopper body 34. The bottom of the installation hole is fixedly connected to the top of the discharge pipe 32. An electromagnetic valve for opening and closing the outer hopper body 31 is provided inside the discharge pipe 32.

[0038] The outer bucket body 31, as the outer structure of the hopper 3, not only serves to bear and protect, but also provides an installation foundation for the inner bucket body 34 and other functional modules. The bottom of the outer bucket body 31 is fixedly connected to the top of the chassis 103 by bolts or welding, ensuring the rigidity and stability of the overall structure. The inner bucket body 34 is set inside the outer bucket body 31, and its bottom opening is connected to the mounting hole at the bottom of the outer bucket body 31 to form a material flow channel. The top of the discharge pipe 32 is fixedly connected to the bottom of the mounting hole. The electromagnetic valve installed inside the discharge pipe 32 is used to control the flow of materials. It can be opened and closed remotely or locally, which allows operators to flexibly adjust according to working conditions.

[0039] There is a cavity between the inner wall of the outer hopper 31 and the outer wall of the inner hopper 34. A vibration motor 33 is fixedly installed inside the cavity, and the output end of the vibration motor 33 is fixedly connected to the outer wall of the inner hopper 34.

[0040] The chamber not only provides installation space for the vibratory motor 33, but also serves as an isolation mechanism to prevent the vibratory motor 33 from directly contacting the material, thus extending its service life. The output end of the vibratory motor 33 is fixedly connected to the outer wall of the inner hopper 34. When the material sticks to or arches on the inner wall of the inner hopper 34, the vibratory motor 33 starts and shakes off the adhering material through high-frequency vibration, restoring the material flow. The start and stop of the vibratory motor 33 can be automatically or manually controlled according to the material status.

[0041] An airflow guiding module 35 is provided inside the outer bucket body 31. The airflow guiding module 35 is located at the center of the top opening of the outer bucket body 31, and the cone tip of the conical baffle 352 is set upward. The airflow guiding module 35 includes a telescopic rod 351 and a conical baffle 352. The top side of the conical baffle 352 is fixedly connected to one end of the telescopic rod 351. The conical baffle 352 is pyramidal in shape, and buffer strips 353 are fixedly connected to the side of the conical baffle 352 from top to bottom.

[0042] The conical baffle 352 is pyramidal in shape with its apex facing upwards. It can decompose the vertical impact force of the material unloaded by the loader into a sliding force along the cone surface in all directions, preventing the material from directly impacting the bottom of the hopper and forming a high-pressure zone. The buffer strips 353 are arranged from top to bottom to further slow down the material's downward speed, prevent material splashing, and guide the material to flow evenly to the annular area on the inner wall of the hopper. One end of the telescopic rod 351 is fixedly connected to the conical baffle 352, and the other end is connected to the buffer module 36 to realize the lifting and lowering adjustment of the conical baffle 352.

[0043] The inner wall of the outer bucket body 31 is provided with a buffer module 36. The buffer module 36 includes a first slider 362, a lead screw 363, a second slider 364, a connecting rod 365, and a mounting bracket 366. There are two mounting brackets 366, which are fixedly connected to the inner walls of opposite sides of the outer bucket body 31. The surface of the mounting bracket 366 is provided with a mounting groove. The lead screw 363 and the connecting rod 365 are respectively set in the mounting grooves opened inside the two mounting brackets 366. One end of the lead screw 363 is rotatably connected to the bottom of the mounting groove. The first slider 362 is threadedly connected to the circumferential side of the lead screw 363. The first slider 362 is slidably connected along the axial direction of the lead screw 363. The side of the first slider 362 is fixedly connected to one end of the telescopic rod 351.

[0044] Two mounting brackets 366 are fixed to the inner walls of opposite sides of the outer bucket body 31, forming a symmetrical support structure to ensure that the conical baffle 352 remains horizontal during lifting. The lead screw 363 is set in the mounting groove of one of the mounting brackets 366, with one end rotatably connected to the bottom of the mounting groove and the other end passing through the top of the mounting bracket 366 and connected to the output end of the motor 361. The first slider 362 is threadedly connected to the lead screw 363. When the lead screw 363 rotates, the first slider 362 slides along the axial direction of the lead screw 363, thereby driving the telescopic rod 351 to rise and fall.

[0045] Both ends of the connecting rod 365 are fixedly connected to the upper and lower sides of the inner wall of the mounting groove. A second slider 364 is installed on the circumferential side of the connecting rod 365. The second slider 364 slides up and down along the axial direction of the connecting rod 365. The side of the second slider 364 is fixedly connected to one end of the telescopic rod 351.

[0046] The cooperation between the connecting rod 365 and the second slider 364 plays a guiding and balancing role. The second slider 364 slides along the axial direction of the connecting rod 365 and moves synchronously with the first slider 362 to ensure that the force on both ends of the telescopic rod 351 is uniform, avoiding jamming or wear caused by uneven load. The upper and lower ends of the connecting rod 365 are fixedly connected to the inner wall of the mounting groove to form a stable guide path, ensuring the smoothness and reliability of the lifting process.

[0047] The top end of the lead screw 363 penetrates the inner wall of the mounting groove to the top of the mounting bracket 366, and the top end of the lead screw 363 is fixedly connected to the output end of the motor 361, which is fixedly connected to the top of the mounting bracket 366.

[0048] Motor 361 serves as the power source for buffer module 36. Its output end is directly connected to the top of lead screw 363. The lead screw 363 can rotate clockwise or counterclockwise by forward and reverse rotation. Motor 361 is fixedly connected to the top of mounting bracket 366 for easy inspection and maintenance. The start, stop and direction of motor 361 can be automatically controlled by the control system according to material characteristics or operation instructions, which improves the automation level of the equipment.

[0049] The feeding belt conveyor 4 is located below the discharge pipe 32, and the discharge end of the feeding belt conveyor 4 is connected to the feed end of the tail frame 203.

[0050] The connection between connecting rod 365 and the second slider 364 serves a guiding and balancing function. The second slider 364 slides axially along connecting rod 365, moving synchronously with the first slider 362 to ensure even force distribution at both ends of the telescopic rod 351, preventing jamming or wear due to uneven loading. The upper and lower ends of connecting rod 365 are fixedly connected to the inner wall of the mounting groove, forming a stable guide path and ensuring the smoothness and reliability of the lifting process. It should be further explained that the outer hopper body 31 serves as the outer shell of the hopper 3, used to support and install the various internal functional components; the inner hopper body 34 is located inside the outer hopper body 31, serving as a cavity that directly contacts the material, and its bottom opening is connected to the discharge pipe 32 through the mounting hole at the bottom of the outer hopper body 31; the discharge pipe 32 is equipped with an electromagnetic valve to control the flow of material in the hopper 3, realizing open-closed discharge; when material adheres to the wall or arches inside the inner hopper body 34, the vibration motor 33 is activated, using high-frequency vibration to dislodge material adhering to the inner hopper body 34. Material is shaken off the inner wall to ensure smooth discharge; the conical baffle 352 is pyramidal in shape to receive material unloaded by the loader, converting the impact force of vertical fall into a sliding force along the cone surface to prevent material from directly impacting the bottom of the hopper 3 and forming a high-pressure zone; buffer strips 353 are arranged from top to bottom to further slow down the material's downward speed, prevent material splashing, and guide the material to flow evenly to the annular area on the inner wall of the hopper 3; the buffer module 36 serves as the height adjustment mechanism for the flow guiding module 35, wherein two mounting brackets 366 are fixed to the inner walls of opposite sides of the outer hopper body 31, and the mounting slots inside are used to accommodate the lead screw 363 and the connecting rod 365; the lead screw 363 is used to convert the rotational motion of the motor 361 into linear motion; by driving the lead screw 363 to rotate through the motor 361, the first slider 362 and the second slider 364 can be driven to rise and fall synchronously, thereby driving the conical baffle 352 to rise and fall as a whole through the telescopic rod 351, realizing the adjustment of the distance between the conical baffle 352 and the discharge pipe 32.

[0051] In this invention, during the stacking operation, when the loader dumps the material into the hopper 3, the material first impacts the conical baffle 352 located at the center of the top of the hopper 3 with the cone apex facing upwards. The conical baffle 352 decomposes the vertically falling impact force into a sliding force along the cone surface in all directions. The material slides down the cone surface, passing through the buffer strips 353 set on the cone surface in stages to gradually decelerate, and finally slides evenly to the annular area near the inner wall of the inner hopper body 34. This process effectively avoids the material directly impacting the bottom of the hopper 3 to form a high-pressure column, preventing the wet clay from hardening due to pressure. After the material enters the inner hopper body 34, it accumulates under the action of gravity. When the solenoid valve in the discharge pipe 32 is opened, the material falls through the discharge pipe 32 onto the feeding belt conveyor 4, which then transports it to the stacking belt conveyor 2 to complete the stacking operation. When the material has too high a moisture content and causes it to stick to the wall or arch inside the inner hopper body 34, the vibration motor 33 can be activated to break the material from the inner hopper body 34 through high-frequency vibration. The adhesive force of the inner wall promotes the material to flow and fall again. For materials with different humidity and flowability, the operator can adjust the height of the conical baffle 352 through the buffer module 36. When conveying high humidity and viscous materials, the motor 361 can be started to drive the lead screw 363 to rotate, which drives the first slider 362 and the second slider 364 to descend synchronously. This causes the telescopic rod 351 to lower the conical baffle 352 to a position close to the feed pipe 32, shortening the material sliding distance and preventing splashing and secondary adhesion. When conveying materials with better flowability, the motor 361 can be started in reverse to raise the conical baffle 352, increasing the material drop space and improving the material discharge efficiency. When the equipment is stopped or needs maintenance, the solenoid valve in the feed pipe 32 can be closed to cut off the material channel between the hopper 3 and the feeding belt 4. At the same time, the conical baffle 352 can be raised to the highest position through the buffer module 36 to free up the internal space of the hopper 3 for personnel to enter for cleaning or maintenance.

[0052] When the equipment is running for a long time or the material humidity changes significantly, the operator can also monitor the material status in the hopper 3 in real time through the control system, such as the material accumulation height and flow rate. Based on the monitoring results, the control system can automatically adjust the height of the conical baffle 352 or the start and stop of the vibration motor 33. For example, when it is detected that the material is accumulated too high or flows slowly in the inner hopper 34, the control system can automatically start the vibration motor 33 or lower the height of the conical baffle 352 to shorten the material sliding path and ensure that the material flows into the discharge pipe 32 continuously and evenly. This control method further improves the automation level and operating efficiency of the equipment.

[0053] The working principle of this invention is as follows: First, the entire machine is moved to the working position by the track 101 of the running mechanism 1, and the pitch angle of the stacker conveyor 2 is adjusted by the pitch module 105 so that the head frame 201 reaches the required stacking height. When the non-continuous feeding equipment such as the loader pours the material into the hopper 3, the material first hits the conical baffle 352 located at the top center of the hopper 3 with the cone tip facing upward. After being decelerated step by step along the cone surface by the buffer strip 353, it slides evenly into the annular area of ​​the inner wall of the inner hopper body 34, effectively avoiding the formation of a high-pressure material column by the vertical impact of the material on the bottom. Subsequently, the electromagnetic valve in the discharge pipe 32 is opened, and the material falls onto the feeding conveyor 4, which continuously transports it to the tail frame 203 of the stacker conveyor 2, and then through the middle frame 202 and the head frame 201 to the discharge end, finally falling into the stockpile or transport vehicle to complete the stacking operation. During this process, the height of the conical baffle 352 can be adjusted by the motor 361 driving the lead screw 363 according to the material moisture content to optimize the flow guiding effect; when the material adheres to the inner wall of the inner bucket 34, the vibration motor 33 can be started to shake off the stuck material; when the equipment is moved, the stacking belt conveyor 2 can be folded by the folding module 204 to reduce the overall size of the machine.
