Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic material conveying equipment, in particular to a feeding system and application thereof. BACKGROUND

[0002] At present, many steel mills take the measures of adding scrap steel crushing materials into the hot metal ladle in advance to save energy and hot metal raw material consumption, melt the scrap steel crushing materials by using the heat of hot metal, achieve the purpose of increasing the amount of hot metal, and save the capital generated by smelting hot metal. Meanwhile, the environmental pollution caused by smelting hot metal can also be reduced, which is an effective means of energy saving and consumption reduction. However, the existing hot metal ladle scrap steel is mostly manually operated by a crane and an electromagnetic disc to suck and hang the materials, the working efficiency is low, and in the process of feeding, the operator needs to operate the crane with high concentration, the labor intensity of the worker is large, in addition, the crushing materials are easy to fall on the site and need to be cleaned, which increases the operation link.

[0003] In view of this, the present application is proposed. SUMMARY

[0004] The purpose of the present application is to provide a feeding system and application thereof, which can mechanically suck and send materials, and can collect the falling materials, which is beneficial to long-term continuous conveying of materials.

[0005] The embodiment of the present application is implemented as follows:

[0006] In a first aspect, the present application provides a feeding system, comprising a support, a travelling crane area, a crawler belt suction and conveying area, and a hopper area.

[0007] The support comprises a first support, a second support and a third support, the planes where the second support and the third support are located are perpendicular to the plane where the first support is located, the travelling crane area is arranged on the first support, the travelling crane area comprises a track and a first movable wheel, the track intersects with the first support in the same plane and is fixed through the intersection point, the first movable wheel is accommodated in the track and is used to drive the first support to move.

[0008] The crawler belt suction and conveying area comprises a base, a magnetic part, a roller, a crawler belt and a crawler belt driving wheel matched with the crawler belt, the base is provided with an opening for passing through the crawler belt, the crawler belt passes through the opening and covers one edge of the base to form a chain-shaped structure with the base, the magnetic part and the roller are fixedly connected with the base and are installed on the edge of the base parallel to the movement direction of the crawler belt and located on the same side of the base, the magnetic part is located between the base and the roller, the crawler belt is annularly surrounded by the roller and the crawler belt driving wheel, the two ends of the crawler belt are respectively a material suction area and a material feeding area, therefore, the base is also divided into a material suction area base and a material feeding area base, and the magnetic part is also divided into a material suction area magnetic part and a material feeding area magnetic part. The material suction area base is connected with the first support, and the material feeding area base is connected with the second support.

[0009] The hopper area comprises a feeding port, a hopper gate and a hopper area fixing part, the hopper area fixing part is arranged in correspondence with the track belt of the feeding area at intervals, and the hopper area fixing part is connected with the third support, one end of the hopper area fixing part away from the material suction area is the feeding port, no magnetic part is arranged on the base of the material suction area corresponding to the feeding port, and the hopper gate is arranged on the feeding port.

[0010] It can be understood that the connection between the track belt and the base can be understood as a chain type connection, that is, the track belt passes through the hollow part inside the annular base and forms a ring by itself. Preferably, the annular plane formed by the track belt and the base is not parallel, for example, the annular base is placed horizontally, and the annular plane of the track belt is placed vertically.

[0011] Since the first support is fixed with the travelling area, and the track belt suction area and the hopper area are also directly or indirectly fixed with the first support, when the first movable wheel of the travelling area slides on the track, the first support and the structures directly or indirectly connected therewith can be driven to move together, so that the materials in different positions can be magnetically attracted, and the materials can also be transported to the positions where they are needed to be placed.

[0012] The rollers provide support for the track belt, and when the track belt driving wheel rotates, the track belt rotates with it, which drives the rollers in contact with the track belt to rotate synchronously, so that the materials can be transported along one end of the track belt to the other end. Therefore, the number of rollers can be multiple, and the multiple rollers are arranged at intervals. In order to achieve better roller support effect, rollers with a width equal to the width of the track belt can be arranged on both sides of the track belt.

[0013] The feeding system provided by the application can transport materials by at least one of the following two ways:

[0014] 1. The track belt rotates, and the materials move from one side of the track belt to the other side;

[0015] 2. The first movable wheel moves on the track to drive the track belt to move along the track, and the materials are transported along the track to the appropriate position.

[0016] Of course, during the movement of the first movable wheel on the track, the track belt can also not carry materials, and is only used to change the position of the feeding device. This case can be applied when the feeding system is located at position A, but the materials are located at position B corresponding to the track. Position A and position B are only used to distinguish different positions on the track, and do not have actual meaning.

[0017] In an optional embodiment, the material suction area magnetic member is fixedly connected with the material suction area base, the material feeding area magnetic member is fixedly connected with the material feeding area base, the material suction area base intersects with the material feeding area base and is connected through a third pin shaft, and a plane where the material suction area base is located is parallel to a plane where the first support is located. Since the material is often stacked at a lower position, such as the ground, or in a waste storage pit, and the device requiring the material is often a reaction tank, a reaction cylinder or the like, there is a height difference between the material and the feeding port. If the crawler belt is arranged horizontally as a whole, it is difficult to transport the material to the target position. Therefore, the base of the crawler belt material suction area is divided into two and connected through a third pin shaft, so as to form a polyline structure in which the material suction area base is lower and the material feeding area base is inclined and raised, thereby realizing the transportation of the material at a low position to the target at a high position. It can be understood that, if there is no height difference between the material and the conveying position, the material suction area base and the material feeding area base can also be arranged in a straight line. It can be understood that the material suction area magnetic member and the material feeding area magnetic member also have a polyline structure.

[0018] In an optional embodiment, a sliding connection assembly is further included, and the material suction area base is selectively slidably connected with the first support through the sliding connection assembly. Since the material suction area base can be separated from the material feeding area base, the slidable connection of the material suction area base with the first support can further improve the flexibility of the material magnetic suction.

[0019] The sliding connection assembly includes a second movable wheel and a connecting member. The second movable wheel is slidably mounted on the first support, and the two ends of the connecting member are respectively connected with the second movable wheel and the material suction area base. The second movable wheel slides on the first support, drives the connecting member to move synchronously, and the connecting member drives the material suction area base below the connecting member to move synchronously, thereby realizing the magnetic suction of the material at the corresponding position on the first support.

[0020] In an optional embodiment, since the position of the material is indefinite, in order to fully consider the height difference between the material and the feeding port, the connecting member is a lifting connecting member, the lifting connecting member is a lifting hydraulic cylinder, a piston rod of the lifting hydraulic cylinder is connected with the material suction area base through a first pin shaft, and an end of the lifting hydraulic cylinder away from the piston rod is connected with the second movable wheel through a second pin shaft. The lifting connecting member can drive the material suction area base to move up and down relative to the first support, thereby realizing the magnetic suction of the material at different heights.

[0021] In an optional embodiment, a suction area hydraulic system is further included, the suction area hydraulic system comprising a three-position four-way electromagnetic reversing valve of "Y" type, a first throttle valve, a first hydraulic pipeline, a hydraulic control check valve and a first oil tank, the first oil tank, the three-position four-way electromagnetic reversing valve of "Y" type, the first throttle valve, the hydraulic control check valve and the lifting hydraulic cylinder are connected in sequence in a forward direction and in reverse sequence to form a loop for controlling the movement of the lifting hydraulic cylinder. The suction area hydraulic system can control the lifting hydraulic cylinder of the suction area to move the suction area base up and down relative to the first support.

[0022] In an optional embodiment, the feed inlet is further provided with a weigher and a gate hydraulic cylinder, the weigher is located below the feed inlet for weighing the mass of the material in the feed inlet, and the gate hydraulic cylinder is arranged on the hopper gate for controlling the opening and closing of the hopper gate. Currently, steel scrap is directly added by using a crown block and an electromagnetic suction disc to magnetically attract the material, so the weight of the steel scrap added each time cannot be known, which increases the uncertainty of smelting in the steel plant. Based on this, the inventor proposes to provide a weigher at the feed inlet, when the hopper gate is closed, the weight of the material accumulated in the feed inlet will be directly displayed on the weigher, when the weight meets the requirements, the gate hydraulic cylinder controls the hopper gate to open, the material is discharged, and after the discharge, the hopper gate is closed to continue collecting the material.

[0023] Preferably, since part of the material may fall off during the conveying process, in order to better collect and clean the material, grooves corresponding to the conveyor belt of the feeding area are arranged on the feeding area fixing member to receive the material falling off the conveyor belt.

[0024] Preferably, when the feeding area base and the suction area base are in a fold line shape, the plane where the feeding area fixing member corresponding to the feeding area base is arranged is parallel to the feeding area base, therefore, the material falling off the conveyor belt will move downward along the feeding area fixing member under the influence of gravity, the feeding area fixing member extends to the third pin shaft and stops, therefore, the material will directly fall back to the suction area after moving downward, and is re-magnetically attracted to the conveyor belt, avoiding secondary cleaning.

[0025] Preferably, a crane driving member is further included, the crane driving member is connected with the first movable wheel for driving the first movable wheel to slide. The crane driving member can be a driving motor, for example.

[0026] Preferably, the crane area further comprises a power trolley line, the power trolley line is arranged below the track and connected with the track through equidistantly spaced rigid members, and can supply power to the first movable wheel to make the first movable wheel slide on the track.

[0027] In optional embodiments, a hopper area hydraulic system is also included, which comprises an "O"-shaped three-position four-way electromagnetic reversing valve, a second throttle valve, a second hydraulic pipeline, a distribution valve, and a second oil tank. The outlet of the second oil tank, the inlet of the "O"-shaped three-position four-way electromagnetic reversing valve, the gate hydraulic cylinder, the distribution valve, the second throttle valve, the outlet of the "O"-shaped three-position four-way electromagnetic reversing valve, and the inlet of the second oil tank are sequentially connected by the second hydraulic pipeline in order to form a loop for controlling the movement of the gate hydraulic cylinder. The hopper area hydraulic system can control the gate hydraulic cylinder to open and close the hopper gate.

[0028] In the hopper area hydraulic system, the second oil tank can be the same as the first oil tank in the material suction area hydraulic system, or can be different.

[0029] Preferably, in order to better fix the structures such as the track suction area and the hopper area connected below the first support, the first support is two, and the two first supports are arranged in parallel and at intervals. In order to ensure the stability of the movement of the first support driven by the first movable wheel, the travel area is also two, and is arranged at the opposite ends of the first support respectively. The first support and the track are alternately connected to form a quadrilateral. It can be understood that the length of the track can be extended, but when the first movable wheel is not moving, a quadrilateral can always be formed between the two tracks and the two first supports.

[0030] In optional embodiments, the second support is two, one end of each of the two second supports is mounted on the two first supports respectively, and the other end of each of the two second supports is mounted on the two parallel edges of the base through two fourth pin shafts respectively. That is, the distance between the two second supports is close to the distance between the two parallel edges of the base, or close to the distance between the two first supports. In some embodiments, the base is placed horizontally, and the two second supports are perpendicular to the base and are fixedly connected to the two parallel edges of the base.

[0031] The third support is also two, one end of each of the two third supports is mounted on the two first supports respectively, and the other end of each of the two third supports is mounted on the hopper area fixing member. That is, the distance between the two third supports is close to the distance between the two parallel edges of the base, or close to the distance between the two first supports. In some embodiments, the base is placed horizontally, and the two third supports are perpendicular to the base and are fixedly connected to the two parallel edges of the base.

[0032] In optional embodiments, the sliding connection assembly is also two, one end of each of the two sliding connection assemblies is mounted on the two first supports respectively, and the opposite end of each of the two sliding connection assemblies is mounted on the two parallel edges of the base.

[0033] In an optional embodiment, a track tensioning device is further installed on the base, and the track tensioning device comprises a cylinder, an elastic member, a first guide wheel, a second guide wheel and an adjusting member. The cylinder is hollow inside, one end of which is fixed to the base, and the other end of which is provided with the adjusting member. The first guide wheel, the second guide wheel and the elastic member are sequentially arranged in the cylinder from the base to the adjusting member. The elastic member is connected to the adjusting member, and is used to adjust the extension and contraction of the elastic member. The track is located between the first guide wheel and the second guide wheel, and the first guide wheel and the second guide wheel are magnetically attracted to the two ends of the track.

[0034] When the material suction area base of the present application can move up and down and / or left and right, since the track is supported by the rollers fixed on the base, the movement of the material suction area base means that the circumference of the track will increase or decrease. In order to ensure that the rollers can support the track and prevent the track from derailing due to the movement of the material suction area base, the present application further provides a track tensioning device. The position of the first guide wheel and the second guide wheel is controlled by the elastic member of the track tensioning device, thereby controlling the contraction and expansion of the track, which is conducive to the magnetic attraction and transportation of the material under different conditions.

[0035] Preferably, the track tensioning device is installed on the feeding area base.

[0036] Preferably, in order to better control the tensioning of the track, the track tensioning device is preferably arranged at a position deviated towards the middle of the track, and the track tensioning device is installed on the base corresponding to the end of the feeding area close to the third pin shaft.

[0037] In an optional embodiment, the feeding system further comprises a controller connected to the gate hydraulic cylinder and the weight sensor. When the weight of the weight sensor reaches a set value, the controller controls the gate hydraulic cylinder to open the hopper gate. When the material is completely discharged, the weight sensor feeds back to the controller, and the controller controls the gate hydraulic cylinder to close the hopper gate.

[0038] Further, the controller is further connected to the trolley driving member to control the speed of the first movable wheel; preferably, the controller controls the first movable wheel to start slowly, accelerate uniformly, walk at a constant speed, and decelerate uniformly, so as to reduce the impact of starting and stopping of the equipment.

[0039] The controller is further connected to the track driving wheel to control the speed of the track driving wheel; preferably, the controller controls the track to start slowly, accelerate uniformly, walk at a constant speed, and decelerate uniformly, so as to improve the service life of the track.

[0040] Further, the controller is further connected to the magnetic member to control the magnetic force of the magnetic member, for example, the magnetic force can be controlled by controlling the current of the electromagnetic plate, so as to magnetically attract the material corresponding to the magnetic force.

[0041] In addition, the controller can also control the hopper gate, the track driving wheel and the trolley driving member in linkage to ensure the safety of material magnetic attraction and transportation. Specifically, when the hopper gate is in the open state, the track driving wheel and the trolley driving member are in the stop state and cannot be started. When the trolley driving member is in the running state, the hopper gate must be in the closed state, and the track driving wheel can continue to run. When the track driving wheel and the trolley driving member are in the running state, the hopper gate cannot be opened.

[0042] Preferably, the above controllers are connected in communication connection, and the specific control method can adopt conventional remote control operation, operation table operation and the like.

[0043] In a second aspect, the application provides an application of the feeding system according to any one of the preceding embodiments in the field of magnetic material transportation.

[0044] The application has the following beneficial effects:

[0045] The application provides a feeding system and application thereof. The trolley area is arranged on the first support, the first movable wheel slides on the track to drive the first support and the belt suction area and the hopper area connected thereto to move, so that the material transportation at different positions is realized. In addition, the belt suction area can attract the material with magnetism to the surface of the belt through the arrangement of the magnetic member, and the material is transported to the feeding port through the movement of the belt. Since the magnetic member is not arranged at the feeding port, the material will fall at the feeding port, so as to fall into the feeding port. When the material accumulates at the feeding port, and the first support and the whole are driven by the trolley to the structure requiring feeding, the feeding gate is opened, and the material enters the structure requiring feeding from the feeding gate. The fixing member of the hopper area can not only fix the hopper area on the first support, but also collect the material falling in the movement of the belt. BRIEF DESCRIPTION OF DRAWINGS

[0058] First embodiment

[0059] Please refer to Figure 1 , Figure 2 and Figure 3 , the present embodiment provides a feeding system 100, which comprises a support, a traveling zone, a crawler suction zone and a hopper zone.

[0060] The support comprises a first support 111, a second support 112 and a third support 113. The planes where the second support 112 and the third support 113 are located are both perpendicular to the plane where the first support 111 is located, the traveling zone is arranged on the first support 111, and the traveling zone comprises a track 121 and a first movable wheel 122, the track 121 intersects with the first support 111 in the same plane and is fixed through the intersection point, and the first movable wheel 122 is accommodated in the track 121 and is used to drive the first support 111 to move.

[0061] The traveling zone further comprises a traveling drive member 123, the traveling drive member 123 is connected with the first movable wheel 122 and is used to drive the first movable wheel 122 to slide. In the present embodiment, the traveling drive member 123 is, for example, a driving motor and the like.

[0062] The driving area further comprises a power slide wire 124 arranged below the track 121 and connected with the track 121 through equidistantly spaced rigid members, which can be used to supply power to the first movable wheel 122 to enable the first movable wheel 122 to slide on the track 121.

[0063] The track suction area comprises a base, magnetic members, rollers 133, a track 134 and a track driving wheel 135 matched with the track 134. The base is provided with an opening 1311 for the track 134 to pass through. The track 134 passes through the hollow of the base and covers one side of the base to form a ring structure. The connection between the track 134 and the base can be understood as a chain connection, that is, the track 134 passes through the opening 1311 on the base and forms a ring by itself.

[0064] The magnetic members and the rollers 133 are fixedly connected with the base and are installed on the side of the base parallel to the movement direction of the track 134, on the same side of the base. The magnetic members are located between the base and the rollers 133. The track 134 is surrounded by the rollers 133 and the track driving wheel 135.

[0065] The rollers 133 provide support for the track 134. When the track driving wheel 135 rotates, the track 134 rotates with it, which in turn drives the rollers 133 in contact with the track 134 to rotate synchronously, thereby enabling the material to be transported along one end of the track 134 to the other end. Therefore, the number of rollers 133 can be multiple, and the multiple rollers 133 are evenly spaced. In order to achieve better support effect of the rollers 133, each roller 133 is a roller 133 with a width equal to the width of the track 134.

[0066] The two ends of the track 134 are respectively a material suction area and a material feeding area. Therefore, the base is divided into a material suction area base 131 and a material feeding area base 136, and the magnetic members are divided into a material suction area magnetic member 132 and a material feeding area magnetic member 137. The material suction area base 131 is connected with the first support 111, and the opening 1311 is also arranged on the material suction area base 131. The material feeding area base 136 is connected with the second support 112.

[0067] The material suction area magnetic member 132 is fixedly connected with the material suction area base 131, the material feeding area magnetic member 137 is fixedly connected with the material feeding area base 136, the material suction area base 131 intersects with the material feeding area base 136 and is connected through the third pin shaft 183, the plane where the material suction area base 131 is located is parallel to the plane where the first support 111 is located, and is perpendicular to the annular plane of the track 134. Since the materials are often stacked in a lower position, such as the ground, or in a waste storage pit, and the equipment that needs these materials is the reaction tank 200, there is a height difference between the materials and the reaction tank 200. If the track 134 is arranged horizontally as a whole, it is difficult to transport the materials to the target position, so the base of the track suction area needs to be divided into two parts and connected by the third pin shaft 183, so as to form a fold line structure in which the material suction area base 131 is lower and the material feeding area base 136 is inclined and raised. Similarly, the material suction area magnetic member 132 and the material feeding area magnetic member 137 also have a fold line structure, so as to realize the transportation of the materials from a low position to a high target position.

[0068] The track suction area further comprises a sliding connection assembly, and the material suction area base 131 is selectively slidably connected with the first support 111 through the sliding connection assembly. Since the material suction area base 131 can be separated from the material feeding area base 136, the material suction area base 131 is arranged to be slidably connected on the first support 111, so as to further improve the flexibility of the material magnetic suction.

[0069] The sliding connection assembly comprises a second movable wheel 138 and a lifting hydraulic cylinder 139. The second movable wheel 138 is slidably installed on the first support 111, the piston rod of the lifting hydraulic cylinder 139 is connected with the material suction area base 131 through the first pin shaft 181, and the end of the lifting hydraulic cylinder 139 away from the piston rod is connected with the second movable wheel 138 through the second pin shaft 182. The second movable wheel 138 slides on the first support 111, drives the connecting member to move synchronously, and the connecting member drives the material suction area base 131 below it to move synchronously, so as to realize the material magnetic suction at the corresponding position on the first support 111. The lifting connecting member can drive the material suction area base 131 to move up and down relative to the first support 111, so as to realize the material magnetic suction at different heights.

[0070] Please refer to Figure 4The track suction area further comprises a suction area hydraulic system, the suction area hydraulic system comprising a Y-shaped three-position four-way electromagnetic reversing valve 141, a first throttle valve 142, a first hydraulic pipeline 145, a hydraulic control check valve 143 and a first oil tank 144, the first oil tank 144, the Y-shaped three-position four-way electromagnetic reversing valve 141, the first throttle valve 142, the hydraulic control check valve 143 and the lifting hydraulic cylinder 139 being connected in sequence in a forward direction and then in a reverse direction through the first hydraulic pipeline 145 to form a loop for controlling the movement of the lifting hydraulic cylinder 139. The suction area hydraulic system can control the lifting hydraulic cylinder 139 of the suction area to move the suction area base 131 up and down relative to the first support 111.

[0071] Please continue to refer to Figure 1 、 Figure 2 and Figure 3 The hopper area comprises a feeding port 151, a hopper gate 152 and a hopper area fixing member 153, the hopper area fixing member 153 being arranged in correspondence with the track 134 of the feeding area at intervals, and the hopper area fixing member 153 being connected with the third support 113, the end of the hopper area fixing member 153 away from the suction area being the feeding port 151, no magnetic member being arranged on the base of the suction area corresponding to the feeding port 151, and the feeding port 151 being provided with the hopper gate 152.

[0072] Further, the feeding port 151 is further provided with a weigher 154 and a gate hydraulic cylinder 155, the weigher 154 being located below the feeding port 151 for weighing the mass of the material in the feeding port 151, and the gate hydraulic cylinder 155 being arranged on the hopper gate for controlling the opening and closing of the hopper gate 152. Currently, when adding steel scrap, the overhead crane is directly used to add the material by the electromagnetic suction disc, so that the weight of the steel scrap added each time cannot be known, which increases the uncertainty of smelting in the steel plant. Based on this, the inventor proposes to arrange the weigher 154 at the feeding port 151, when the hopper gate 152 is closed, the weight of the material accumulated in the feeding port 151 is directly displayed on the weigher 154, when the weight meets the requirements, the gate hydraulic cylinder 155 controls the hopper gate 152 to open, and the material is discharged, after the discharge, the hopper gate 152 is closed, and the material continues to be collected.

[0073] Further, the base is further provided with a track tensioning device, which comprises a cylinder 171, an elastic member 172, a first guide wheel 173, a second guide wheel 174 and an adjusting member 175. The cylinder 171 is hollow, one end of which is fixed to the base, and the other end of which is provided with the adjusting member 175. The first guide wheel 173, the second guide wheel 174 and the elastic member 172 are sequentially arranged in the cylinder 171 from the base to the adjusting member 175. The elastic member 172 is connected to the adjusting member 175, and is used to adjust the extension and contraction of the elastic member 172. The track 134 is located between the first guide wheel 173 and the second guide wheel 174, and the first guide wheel 173 and the second guide wheel 174 are magnetically attracted to the two ends of the track 134.

[0074] Since the material suction area base 131 of the embodiment is movable up and down and / or left and right, and the track 134 is supported by the rollers 133 fixed to the base, the movement of the material suction area base 131 means that the circumference of the track 134 will increase or decrease. In order to ensure that the rollers 133 can support the track 134 and prevent the track 134 from derailing due to the movement of the material suction area base 131, the track tensioning device is provided, which controls the positions of the first guide wheel 173 and the second guide wheel 174 through the elastic member 172 of the track tensioning device, thereby controlling the contraction and expansion of the track 134, which is conducive to the magnetic attraction and transportation of the material under different conditions.

[0075] In order to better control the tensioning of the track 134, the track tensioning device is preferably arranged at a position deviated to the middle of the track 134. Specifically, the track tensioning device is arranged on the base corresponding to the end of the feeding area close to the third pin shaft 183.

[0076] Please refer to Figure 4 , the hopper area further comprises a hopper area hydraulic system, which comprises an "O"-shaped three-position four-way electromagnetic reversing valve 161, a second throttle valve 162, a second hydraulic pipeline 164, a distribution valve 163 and a second oil tank. The outlet of the second oil tank, the inlet of the "O"-shaped three-position four-way electromagnetic reversing valve 161, the gate hydraulic cylinder 155, the distribution valve 163, the second throttle valve 162, the outlet of the "O"-shaped three-position four-way electromagnetic reversing valve 161 and the inlet of the second oil tank are sequentially connected through the second hydraulic pipeline 164 to form a loop, which is used to control the movement of the gate hydraulic cylinder 155. The hopper area hydraulic system can control the opening and closing of the hopper gate 152 driven by the gate hydraulic cylinder 155.

[0077] Please refer to Figure 1 , Figure 2 and Figure 3In order to better collect and clean the materials, grooves (not shown in the figure) corresponding to the feeding area track 134 are arranged on the hopper area fixing member to receive the materials falling from the feeding area track 134.

[0078] When the feeding area base 136 and the material suction area base 131 of the embodiment have a fold line structure, the plane where the hopper area fixing member corresponding to the feeding area base 136 is arranged is parallel to the feeding area base 136. Therefore, the materials falling from the track 134 will move downward along the hopper area fixing member under the influence of gravity, and the hopper area fixing member will stop at the third pin shaft 183. Thus, the materials will directly fall back to the material suction area after moving downward, and will be magnetically attracted to the track 134 again, avoiding secondary cleaning.

[0079] Since the first support 111 is fixed with the trolley area, and the track suction area and the hopper area are also directly or indirectly fixed with the first support 111, when the first movable wheel 122 of the trolley area slides on the track 121, the first support 111 and the structures directly or indirectly connected thereto can be moved together. Therefore, the materials at different positions can be magnetically attracted, and the materials can also be transported to the positions where they need to be placed.

[0080] In order to better fix the structures such as the track suction area and the hopper area connected to the first support 111, the first support 111 is two, and the two first supports 111 are arranged in parallel. In order to ensure the stability of the first support 111 when the first movable wheel 122 drives the first support 111 to move, the trolley area is also two, and is arranged at the opposite ends of the first support 111. The first support 111 and the track 121 are alternately connected to form a quadrilateral. It can be understood that the length of the track 121 can be extended, but when the first movable wheel 122 does not move, a quadrilateral can always be formed between the two tracks 121 and the two first supports 111.

[0081] The second support 112 is two, one end of each of the two second supports 112 is mounted on the two first supports 111, and the other end of each of the two second supports 112 is mounted on the two parallel edges of the base through the two fourth pin shafts 184. That is, the distance between the two second supports 112 is close to the distance between the two parallel edges of the base, or close to the distance between the two first supports 111.

[0082] The third support 113 is also two, one end of each of the two third supports 113 is mounted on the two first supports 111, and the other end of each of the two third supports 113 is mounted on the hopper area fixing member 153. That is, the distance between the two third supports 113 is close to the distance between the two parallel edges of the base, or close to the distance between the two first supports 111.

[0083] The two sliding connection assemblies are respectively installed on the two first supports 111 at one end and on the two parallel edges of the base at the other end.

[0084] Further, the feeding system 100 further comprises a controller (not shown in the figure). The controller is connected with the gate hydraulic cylinder 155 and the weighter 154. When the weight of the weighter 154 reaches a set value, the controller controls the gate hydraulic cylinder 155 to open the hopper gate 152. When the feeding is completed, the weighter 154 feeds back to the controller, and the controller controls the gate hydraulic cylinder 155 to close the hopper gate 152.

[0085] The controller is also connected with the travelling crane driving member 123 to control the speed of the first movable wheel 122 driven by the travelling crane driving member 123; preferably, the controller controls the first movable wheel 122 to start slowly, accelerate uniformly, walk at a constant speed, and decelerate uniformly, so as to reduce the impact of starting and stopping of the equipment.

[0086] The controller is also connected with the driving motor 1351 of the track driving wheel 135 to control the speed of the track 134 driven by the track driving wheel 135; preferably, the controller controls the track 134 to start slowly, accelerate uniformly, walk at a constant speed, and decelerate uniformly, so as to improve the service life of the track 134.

[0087] The controller is also connected with the magnetic member to control the magnetic force of the magnetic member, for example, the magnetic force of the electromagnetic plate can be controlled by controlling the current of the electromagnetic plate, so as to magnetically attract the material corresponding to the magnetic force.

[0088] In addition, the controller can also control the hopper gate 152, the track driving wheel 135 and the travelling crane driving member 123 in linkage, so as to ensure the safety of material magnetic attraction and transportation. Specifically, when the hopper gate 152 is in an open state, the track driving wheel 135 and the travelling crane driving member 123 are in a stopped state and cannot be started. When the travelling crane driving member 123 is in a running state, the hopper gate 152 must be in a closed state, and the track driving wheel 135 can continue to run. When the track driving wheel 135 and the travelling crane driving member 123 are in a running state, the hopper gate 152 cannot be opened.

[0089] The feeding system 100 provided by the embodiment can transport the material by at least one of the following modes:

[0090] 1. The track 134 rotates to move the material from one side of the track 134 to the other side.

[0091] 2. The first movable wheel 122 moves on the track 121 to drive the track 134 to move along the track 121, so as to transport the material along the track 121 to a suitable position.

[0092] 3, the lifting hydraulic cylinder 139 drive suction area base 131 lifting, or through the second movable wheel 138 drive lifting hydraulic cylinder 139 and suction area base 131 left and right move the magnetic material, after the end of the magnetic suction through the third pin shaft 183 and feeding area fixed seat connection conveying material. It can be understood that when the suction area fixed seat from the third pin shaft 183, the track drive wheel 135 does not work, when the suction area fixed seat and the third pin shaft 183 connection, the track drive wheel 135 work.

[0093] Of course the first movable wheel 122 in the process of moving on the track 121, the track 134 can also not carry material, only for changing the position of the feeding device, the case can be applied in feeding system 100 is located in position A, but the material in the track 121 corresponding to the B position when using, wherein A position and B position is only to facilitate the distinction between different positions on the track 121, does not have the actual meaning.

[0094] The above is only the preferred embodiment of the present application, and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
