The present application relates to the field of conveying equipment, and particularly provides a discharging device for a transfer machine. The discharging device for the transfer machine comprises a support frame, a plurality of roller assemblies and a hopper. The support frame is arranged on the transfer machine and is movable relative to the transfer machine along a conveying direction of the transfer machine and / or a reverse direction of the conveying direction. The plurality of roller assemblies are arranged on the support frame and are spaced apart along the conveying direction. The roller assemblies are arranged to turn and support a conveying belt of the transfer machine, and to form a discharging portion of the conveying belt. The hopper is arranged on the support frame and is located on one side of the discharging portion in the conveying direction. An outlet is arranged at one end of the hopper which is perpendicular to the conveying direction. The discharging device for the transfer machine turns the conveying belt of the transfer machine by the roller assemblies, so that the material on the conveying belt is discharged to the hopper at the discharging portion, and then is released to a conveyor through the outlet. Since the support frame is movable along the conveying direction and / or the reverse direction of the conveying direction, the outlet can be maintained above the conveyor.

Description

Technical Field

[0001] This invention relates to the field of conveying equipment, and more specifically to an unloading device for a transfer machine. Background Technology

[0002] A transfer conveyor is a conveying device installed in a mine roadway. It is used to connect mining equipment and a conveyor, or to connect crushing equipment and a conveyor, to transfer the ore produced by mining or crushing to the conveyor.

[0003] As the working face is mined, the mining and crushing equipment needs to be moved forward, increasing the distance between the mining or crushing equipment and the conveyor. Since the length of the transfer conveyor is fixed, related technologies address this by replacing the transfer conveyor with one of different lengths or moving the conveyor forward to ensure the transfer of ore. However, replacing the transfer conveyor and moving the conveyor forward are both costly, complex to operate, and prone to damaging equipment and creating safety hazards. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in the related art. To this end, this invention proposes a discharge device for a transfer machine.

[0005] The unloading device for a transfer machine of the present invention includes:

[0006] A support frame is provided on the frame of the transfer machine or spans over the frame of the transfer machine, and the support frame is movable relative to the transfer machine along the conveying direction of the transfer machine and / or in the opposite direction of the conveying direction.

[0007] The idler assembly comprises multiple idler assemblies, which are disposed on the support frame and arranged at intervals along the conveying direction. The idler assembly is used to rotate the frame and support the conveyor belt of the transfer machine, and to make the conveyor belt form an unloading section.

[0008] A hopper is provided on the support frame and located on one side of the unloading part in the conveying direction to receive unloading from the unloading part. The hopper has a discharge port at one end orthogonal to the conveying direction.

[0009] Furthermore, the plurality of said idler assemblies include a loading section and an unloading section, each having at least two said idler assemblies. Along the conveying direction, the unloading section is located downstream of the loading section, and the last idler assembly of the loading section is located above the first idler assembly of the unloading section, so that the conveyor belt forms the unloading section.

[0010] Furthermore, along the conveying direction, at least the portion of the idler roller assembly at the beginning of the material-carrying section is arranged obliquely from bottom to top along the conveying direction.

[0011] Furthermore, the material-carrying section includes a first section and a second section, each having at least two idler roller assemblies. The at least two idler roller assemblies of the first section are arranged obliquely from bottom to top along the conveying direction. The second section is located downstream of the first section along the conveying direction, and the at least two idler roller assemblies of the second section are arranged horizontally along the conveying direction.

[0012] Furthermore, the last idler assembly of the material-carrying section is a first steering roller, and at least two idler assemblies of the unloaded section include a second steering roller. The second steering roller is located below the first steering roller. In the horizontal projection plane, the projection of the second steering roller is located on the opposite side of the projection of the first steering roller in the conveying direction. The conveyor belt has a front and a back side arranged opposite to each other. The front side is used to carry materials. All the idler assemblies of the material-carrying section are used to abut against the back side, and the second steering roller is used to abut against the front side.

[0013] Furthermore, at least two of the idler roller assemblies in the unloaded portion also include auxiliary rollers, which are located vertically between the first steering roller and the second steering roller, and in the horizontal projection plane, the projection of the auxiliary roller is located between the projection of the first steering roller and the projection of the second steering roller, and the auxiliary roller is used to abut against the back side.

[0014] Furthermore, the hopper is located on one side of the first steering roller, the second steering roller, and the auxiliary roller in the conveying direction, and the top of the hopper is provided with a feed inlet, the height of which is lower than that of the first steering roller.

[0015] Furthermore, the support frame includes:

[0016] A base for mounting on the frame and movable relative to the frame along the conveying direction and in the opposite direction of the conveying direction; the base includes the unloaded portion and the hopper.

[0017] A crossbeam extends along the conveying direction and is inclined from bottom to top. The first end of the crossbeam in the conveying direction is mounted on the frame and is movable relative to the frame along the conveying direction and in the opposite direction. The last end of the crossbeam in the conveying direction is connected to the base. The crossbeam is provided with at least a portion of the idler roller assembly of the material-carrying section.

[0018] Furthermore, the unloading device for the transfer machine also includes a traveling wheel. The base and the first end of the crossbeam are respectively provided with the traveling wheel. The traveling wheel includes a rotating shaft and wheel bodies provided at both ends of the rotating shaft. The rotating shaft extends in a direction orthogonal to the conveying direction, and the wheel bodies are used to be mounted on the frame.

[0019] Furthermore, the unloading device for the transfer machine also includes a driving component, which is disposed on the base and connected to the traveling wheel to drive the traveling wheel to rotate about the axial direction of the traveling wheel.

[0020] This invention relates to a discharge device for a transfer conveyor. Multiple idler roller assemblies and a hopper are mounted on a support frame. The support frame is positioned on or across the frame of the transfer conveyor. Along the conveying direction of the transfer conveyor, the conveyor belt is transferred from the support rollers to the multiple idler roller assemblies and then back to the support rollers, allowing material on the conveyor belt to be transferred to the idler roller assemblies and discharged into the hopper at the discharge section. The material is then released onto the conveyor through the hopper's outlet. Because the support frame can move relative to the transfer conveyor along its conveying direction and / or in the opposite direction, when the mining or crushing equipment moves forward and the transfer conveyor moves forward accordingly, the support frame can be driven to move in the opposite direction of the transfer conveyor's movement on the frame. This ensures that the hopper's outlet remains positioned relative to the conveyor, guaranteeing that the material conveyed by the transfer conveyor is always discharged onto the conveyor even when the distance between the mining or crushing equipment and the conveyor changes.

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is for reference. Figure 1 and Figure 2 A material unloading device for a transfer machine according to an embodiment of the present invention is described.

[0028] like Figure 1 and Figure 2 As shown, the unloading device 10 for a transfer machine according to an embodiment of the present invention includes a support frame 1, a roller assembly 2, and a hopper 3.

[0029] The support frame 1 is mounted on the frame of the transfer machine 20, or spans over the frame of the transfer machine 20, and the support frame 1 is movable relative to the transfer machine 20 in the conveying direction and / or in the opposite direction of the conveying direction. Multiple idler roller assemblies 2 are mounted on the support frame 1 and arranged at intervals along the conveying direction. The idler roller assemblies 2 are used to rotate and support the conveyor belt 201 of the transfer machine 20, forming a discharge section. A hopper 3 is mounted on the support frame 1 and located on the side of the discharge section in the conveying direction to receive discharge from the discharge section. The hopper 3 has a discharge port 31 at the end orthogonal to the conveying direction.

[0030] Specifically, the transfer conveyor 20 extends longitudinally within the mine roadway, with its conveying direction from front to back. The front end of the transfer conveyor 20 can be directly connected to mining equipment (not shown in the figure), or it can be connected to the mining equipment via crushing equipment (not shown in the figure). The mining equipment moves laterally to mine the working face, and the mined ore is either directly fed to the transfer conveyor 20 or crushed by the crushing equipment before being fed to the transfer conveyor 20. The rear end of the transfer conveyor 20 spans above a conveyor (not shown in the figure), which extends laterally to receive the ore transferred by the transfer conveyor 20 and transport it out of the roadway. The conveyor can be a belt conveyor or a railcar device.

[0031] The transfer machine 20 includes a frame, support rollers 202 and a conveyor belt 201. The frame extends in the front-to-back direction and is provided with multiple support rollers 202 arranged at intervals in the front-to-back direction. The conveyor belt 201 is provided on the multiple support rollers 202 to transfer and transport ore.

[0032] During the mining operation, the crushing equipment and transfer conveyor 20 move synchronously with the mining equipment in the left-right direction, with the rear end of the transfer conveyor 20 moving relative to the conveyor in the left-right direction. When the mining equipment changes working faces, it needs to move in the front-back direction, preferably forward. At this time, the crushing equipment and transfer conveyor 20 move forward synchronously with the mining equipment, and the rear end of the transfer conveyor 20 remains positioned above the conveyor. Therefore, the length of the transfer conveyor 20 is greater than the distance between the mining equipment and the conveyor.

[0033] like Figure 1 and Figure 2 The support frame 1 can be installed on the frame of the transfer machine 20, or it can be located on the bottom surface of the tunnel and spans across the frame of the transfer machine 20 in the left-right direction. In other words, the support frame 1 is an arch shape that spans across the frame in the left-right direction. Preferably, the support frame 1 is installed on the frame of the transfer machine 20. Furthermore, the support frame 1 can move relative to the frame in the front-back direction.

[0034] The support frame 1 is equipped with multiple idler roller assemblies 2, which are arranged at intervals in the front-to-back direction. From front to back, the conveyor belt 201 is transferred from one upstream support roller 202 in the conveying direction to the multiple idler roller assemblies 2, forming a discharge section on each assembly. Then, the conveyor belt 201 returns from the idler roller assemblies 2 to another downstream support roller 202 in the conveying direction. In other words, the conveyor belt 201 is mounted on the unloading device 10 of the transfer machine 20 and then returns to the transfer machine 20. The ore conveyed by the conveyor belt 201 moves along with the conveyor belt 201 to the multiple idler roller assemblies 2 and is unloaded at the discharge section.

[0035] The support frame 1 is also equipped with a hopper 3, which is located behind the unloading section to collect the ore unloaded from the unloading section. The left or right end of the hopper 3 is provided with a discharge port to release the ore in the hopper 3 and let it fall onto the conveyor, while preventing the ore from falling onto the transfer machine 20. The hopper 3 is preferably a V-shaped hopper.

[0036] When the mining equipment changes working faces, the transfer machine 20 moves forward relative to the conveyor along with the mining equipment. At this time, the drive support frame 1 moves backward relative to the transfer machine 20 so that the position of the hopper 3 relative to the conveyor remains unchanged. This ensures that the ore transferred by the transfer machine 20 can always be released from the hopper 3 onto the conveyor through the unloading device 10 for the transfer machine, avoiding the need to replace with other models of transfer machines or move the conveyor.

[0037] This invention relates to a discharge device for a transfer conveyor. Multiple idler roller assemblies and a hopper are mounted on a support frame. The support frame is positioned on or across the frame of the transfer conveyor. Along the conveying direction of the transfer conveyor, the conveyor belt is transferred from the support rollers to the multiple idler roller assemblies and then back to the support rollers, allowing material on the conveyor belt to be transferred to the idler roller assemblies and discharged into the hopper at the discharge section. The material is then released onto the conveyor through the hopper's outlet. Because the support frame can move relative to the transfer conveyor along its conveying direction and / or in the opposite direction, when the mining or crushing equipment moves forward and the transfer conveyor moves forward accordingly, the support frame can be driven to move in the opposite direction of the transfer conveyor's movement on the frame. This ensures that the hopper's outlet remains positioned relative to the conveyor, guaranteeing that the material conveyed by the transfer conveyor is always discharged onto the conveyor even when the distance between the mining or crushing equipment and the conveyor changes.

[0038] In some embodiments, the plurality of idler roller assemblies 2 include a loading section 21 and an unloading section 22, each having at least two idler roller assemblies 2. Along the conveying direction, the unloading section 22 is located downstream of the loading section 21, and the last idler roller assembly 2 of the loading section 21 is located above the first idler roller assembly 2 of the unloading section 22, so that the conveyor belt 201 forms an unloading section.

[0039] like Figure 1 and Figure 2 As shown, the multiple idler roller assemblies 2 include a loading section 21 and an unloading section 22. Both the loading section 21 and the unloading section 22 have at least two idler roller assemblies 2. The loading section 21 is located upstream of the unloading section 22 in the conveying direction. The portion of the conveyor belt 201 on the loading section 21 carries ore, while the portion of the conveyor belt 201 on the unloading section 22 does not carry ore. In other words, the conveyor belt 201 first reaches the loading section 21, then unloads the ore, then reaches the unloading section 22, and then returns to the support roller 202 of the transfer machine 20.

[0040] The last idler assembly 2 of the loading section 21 is located above the first idler assembly 2 of the unloading section 22. After passing the last idler assembly 2 of the loading section 21, the conveyor belt 201 bends downward to the first idler assembly 2 of the unloading section 22, thereby bending the conveyor belt 201 to form a discharge section. The ore is thrown into the hopper 3 by the bending discharge section under the conveying inertia of the conveyor belt 201.

[0041] In some embodiments, along the conveying direction, at least the portion of the idler roller assembly 2 at the beginning of the material-carrying portion 21 is arranged obliquely from bottom to top along the conveying direction.

[0042] like Figure 1 and Figure 2As shown, there are multiple idler roller assemblies 2 of the material-carrying section 21, wherein at least two idler roller assemblies 2 located at the front end of the material-carrying section 21 are spaced apart in a front-to-back direction and arranged obliquely from bottom to top, so that the portion of the conveyor belt 201 at least at the front end of the material-carrying section 21 forms a slope, so that the conveyor belt 201 carrying ore is transferred from the support roller 202 to the idler roller assembly 2.

[0043] In some embodiments, the material-carrying section 21 includes a first section 211 and a second section 212. Both the first section 211 and the second section 212 have at least two idler roller assemblies 2. The at least two idler roller assemblies 2 of the first section 211 are arranged obliquely from bottom to top along the conveying direction. The second section 212 is located downstream of the first section 211 along the conveying direction. The at least two idler roller assemblies 2 of the second section 212 are arranged horizontally along the conveying direction.

[0044] like Figure 1 and Figure 2 As shown, the material-carrying section 21 includes a first section 211 and a second section 212. Both the first section 211 and the second section 212 have at least two idler roller assemblies 2. The first section 211 is located upstream of the second section 212 in the conveying direction. During the conveying process, the conveyor belt 201 is first transferred to the first section 211 by a support roller 202 upstream in the conveying direction, and then moves to the second section 212.

[0045] Preferably, the first section 211 has multiple idler roller assemblies 2, and the second section 212 has two idler roller assemblies 2. All the idler roller assemblies 2 of the first section 211 are spaced apart in a front-to-back direction and arranged obliquely from bottom to top so that the conveyor belt 201 forms a slope on the first section 211. All the idler roller assemblies 2 of the second section 212 are spaced apart in a front-to-back direction and arranged horizontally. The end of the second section 212 forms a discharge section. The horizontal arrangement of all the idler roller assemblies 2 of the second section 212 facilitates the discharge of ore from the discharge section.

[0046] Preferably, each idler assembly 2 in the first section 211 has two first rollers, which are spaced apart in the left-right direction. The first roller on the left extends from left to right and is inclined downwards, while the first roller on the right extends from right to left and is inclined downwards, so that the conveyor belt 201 forms a downwardly convex arc shape in the first section 211, preventing the ore from detaching from the conveyor belt 201. Each idler assembly 2 in the second section 212 is a second roller extending horizontally in the left-right direction, so that the ore can be thrown out from the unloading section. Since the conveyor belt 201 in the unloaded section 22 does not carry ore, all idler assemblies 2 in the unloaded section 22 are preferably third rollers extending horizontally in the left-right direction.

[0047] It is understood that the material-carrying section is not limited to including the first and second sections. In other embodiments, all the roller assemblies of the material-carrying section are spaced apart in a front-to-back direction and arranged obliquely from bottom to top.

[0048] In some embodiments, the last idler assembly 2 of the material-carrying section 21 is a first steering roller 213, and at least two idler assemblies 2 of the unloaded section 22 include a second steering roller 221. The second steering roller 221 is located below the first steering roller 213. In the horizontal projection plane, the projection of the second steering roller 221 is located on the opposite side of the projection of the first steering roller 213 in the conveying direction. The conveyor belt 201 has a front and a back arranged opposite to each other. The front is used to carry materials. All idler assemblies 2 of the material-carrying section 21 are used to abut against the back, and the second steering roller 221 is used to abut against the front.

[0049] like Figure 2 As shown, the conveyor belt 201 has a front and a back side arranged opposite to each other. The front side is used to carry ore. When the conveyor belt 201 is on the support roller 202, the front side is above the back side, and the support roller 202 abuts against the back side.

[0050] The last idler assembly 2 of the second segment 212 is a first steering roller 213. At least two idler assemblies 2 of the unloaded portion 22 include a second steering roller 221. Preferably, the unloaded portion 22 includes two idler assemblies 2, one of which is a second steering roller 221. In the vertical projection plane, the projection of the second steering roller 221 is below the projection of the first steering roller 213. In the horizontal projection plane, the projection of the second steering roller 221 is in front of the projection of the first steering roller 213. In other words, the second steering roller 221 is located in front of and below the first steering roller 213.

[0051] When the conveyor belt 201 is on the material-carrying section 21, all the idler roller assemblies 2 of the material-carrying section 21 are in contact with the back side. After passing the first steering roller 213, the conveyor belt 201 turns to extend toward the second steering roller 221. In other words, the conveyor belt 201 extends from front to back on the second section 212, and after passing the first steering roller 213, it changes to extend from back to front and downwards, so that the conveyor belt 201 forms a rearward protruding unloading part at the first steering roller 213, so that the ore on the conveyor belt 201 can be thrown out by the unloading part and fall into the hopper 3.

[0052] When the conveyor belt 201 reaches the second guide roller 221, it changes to face-to-face contact with the second guide roller 221. After passing the second guide roller 221, the conveyor belt 201 changes direction and extends towards the rear support roller 202. In other words, after passing the second guide roller 221, the conveyor belt 201 extends from front to back, which can be from front to back and upward, or from front to back and downward, so that the conveyor belt 201 can return from the unloading device 10 for the transfer machine to the transfer machine 20. Preferably, the second guide roller 221 is located in front of and below the rear support roller 202. After passing the second guide roller 221, the conveyor belt 201 extends from front to back and upward, and then its back side abuts against the rear support roller 202, thereby ensuring that the conveyor belt 201 on the support roller 202 remains taut. It is understood that the second guide roller 221 can also be located at the same height as the rear support roller 202. Other idler roller assemblies 2 can also be provided between the second guide roller 221 and the rear support roller 202.

[0053] In some embodiments, at least two idler roller assemblies 2 of the unloaded portion 22 further include an auxiliary roller 222, which is located vertically between the first steering roller 213 and the second steering roller 221. In the horizontal projection plane, the projection of the auxiliary roller 222 is located between the projection of the first steering roller 213 and the projection of the second steering roller 221. The auxiliary roller 222 is used to abut against the back side.

[0054] like Figure 2 As shown, the other of the two idler roller assemblies 2 in the unloaded section 22 is an auxiliary roller 222. In the vertical projection plane, the projection of the auxiliary roller 222 is located between the projections of the first guide roller 213 and the second guide roller 221. In the horizontal projection plane, the projection of the auxiliary roller 222 is also located between the projections of the first guide roller 213 and the second guide roller 221. In other words, the auxiliary roller 222 is located below and in front of the first guide roller 213 and above and behind the second guide roller 221. The auxiliary roller 222 abuts against the back of the conveyor belt 201 and acts as a buffer between the first guide roller 213 and the second guide roller 221, preventing the conveyor belt 201 from being torn or broken due to excessive tension between the first guide roller 213 and the second guide roller 221.

[0055] In some embodiments, the hopper 3 is located on one side of the first steering roller 213, the second steering roller 221 and the auxiliary roller 222 in the conveying direction, and the top of the hopper 3 is provided with a feed inlet, the height of which is lower than that of the first steering roller 213.

[0056] like Figure 1 and Figure 2As shown, the hopper 3 is located behind the first steering roller 213, the second steering roller 221 and the auxiliary roller 222. The top of the hopper 3 is open to form a feed inlet. The height of the feed inlet is lower than that of the first steering roller 213. Preferably, the front end of the feed inlet is located directly below the first steering roller 213 to ensure that the ore is fed into the feed inlet from the discharge hopper.

[0057] In some embodiments, the support frame 1 includes a base 11 and a crossbeam 12. The base 11 is mounted on the frame and is movable relative to the frame in the conveying direction and in the opposite direction of the conveying direction. The base 11 has an unloaded portion 22 and a hopper 3. The crossbeam 12 extends in the conveying direction and is inclined from bottom to top. The first end of the crossbeam 12 in the conveying direction is mounted on the frame and is movable relative to the frame in the conveying direction and in the opposite direction of the conveying direction. The last end of the crossbeam 12 in the conveying direction is connected to the base 11. The crossbeam 12 has at least a portion of the idler roller assembly 2 of the material-carrying portion 21.

[0058] like Figure 1 and Figure 2 As shown, the support frame 1 includes a base 11 and a crossbeam 12. The height of the base 11 is greater than the height of the crossbeam 12. The crossbeam 12 extends in the front-to-back direction. The base 11 is located at the rear end of the crossbeam 12, and the rear end of the crossbeam 12 is connected to the top of the base 11. The bottom of the base 11 and the front end of the crossbeam 12 are both used to be mounted on the frame and can move in the front-to-back direction relative to the frame. Therefore, the crossbeam 12 extends from front to back and is inclined upward.

[0059] All idler roller assemblies 2 of the first section 211 are located on the top of the crossbeam 12, so that all idler roller assemblies 2 of the first section 211 are spaced apart in a front-to-back direction and arranged obliquely from bottom to top. All idler roller assemblies 2 of the second section 212 are located on the top of the base 11, and the hopper 3 is located at the rear end of the base 11, so that the ore is unloaded from the conveyor belt 201 on the second section 212 into the hopper 3. All idler roller assemblies 2 of the unloaded section 22 are located inside the base 11, so as to facilitate the installation of the idler roller assemblies 2 of the unloaded section 22 and to avoid interference between the idler roller assemblies 2 of the unloaded section 22 and the hopper 3, as well as interference between the conveyor belt 201 and the hopper 3.

[0060] In some embodiments, the unloading device 10 for the transfer machine of the present invention further includes a traveling wheel 4. The first ends of the base 11 and the crossbeam 12 are respectively provided with the traveling wheel 4. The traveling wheel 4 includes a rotating shaft and wheel bodies provided at both ends of the rotating shaft. The rotating shaft extends in a direction orthogonal to the conveying direction, and the wheel bodies are used to be provided on the frame.

[0061] like Figure 1As shown, the traveling wheel 4 includes a rotating shaft and a wheel body. The rotating shaft extends in the left-right direction and is connected to the support frame 1. Wheel bodies are respectively provided at the left and right ends of the rotating shaft. The wheel bodies are mounted on the frame. Preferably, the frame has a conveying trough for accommodating the conveyor belt 201. The left and right ends of the conveying trough each have a track. The wheel body is mounted on the track on the corresponding side to move in the front-back direction under the guidance of the track. It should be noted that the traveling wheel 4 can be configured such that the rotating shaft can rotate axially relative to the support frame 1, or the wheel body can rotate axially relative to the rotating shaft.

[0062] The base 11 has corresponding wheels 4 at its bottom and the front end of the crossbeam 12. Preferably, the base 11 has at least two wheels 4 arranged at intervals in the front-rear direction at its bottom. The front end of the crossbeam 12 is triangular in the projection plane orthogonal to the left-right direction and has a pointed tip at the front end, on which a wheel 4 is provided.

[0063] In some embodiments, the unloading device 10 for the transfer machine of the present invention further includes a driving member (not shown in the figure), which is disposed on the base 11 and connected to the traveling wheel 4 to drive the traveling wheel 4 to rotate about the axial direction of the traveling wheel 4.

[0064] Specifically, the base 11 is equipped with a driving component, preferably a rotary motor. The rotating shaft of the rotary motor is connected to the rotating shaft of at least one traveling wheel 4. This connection can be via gear transmission or belt transmission, so that the traveling wheel 4 connected to the rotary motor acts as the driving wheel, thereby causing the support frame 1 to move along the front-back direction on the frame under the drive of the driving component.

[0065] In some embodiments, the unloading device 10 for the transfer machine of the present invention further includes a controller and a displacement sensor. The transfer machine 20 has a speed sensor for obtaining the moving speed of the transfer machine 20 in the forward and backward direction. The displacement sensor is disposed on the hopper 3 for obtaining the distance between the discharge port 31 and the conveyor in the forward and backward direction. The controller is electrically connected to the speed sensor, the displacement sensor and the drive unit respectively. When the transfer machine 20 moves forward, the controller obtains the speed value sensed and transmitted by the speed sensor and the distance value sensed and transmitted by the displacement sensor, and then starts the drive unit so that the support frame 1 moves backward in the opposite direction at the same speed value as the transfer machine 20, so that the distance value is maintained within the range required for operation, thereby ensuring that the discharge port 31 and the conveyor are set opposite each other in the vertical direction. In other words, it ensures that the discharge port 31 is located above the conveyor.

[0066] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
