Description

Technical Field

[0001] The utility model relates to the field of material loading, unloading and conveying devices, and particularly relates to a two-way unloading device that can flexibly unload materials to both sides. Background Art

[0002] In the fields of modern industrial production and logistics transportation, efficient material unloading is one of the key factors to improve the overall work efficiency. Most of the existing unloading technologies can only achieve single-direction unloading. For occasions that require rapid change of the unloading direction, such equipment is complex to operate and has high space requirements.

[0003] The existing unloading technologies mainly include plough-type unloading devices. The installation position of the plough-type unloading device is limited. It can only be installed on belt conveyors, has high space requirements, is troublesome to install and debug, and has a narrow application range. For example, the two-way plough-type unloading device with the authorization announcement number of CN 208470965U can unload materials in two directions, but has high space requirements, a complex structure, and is quite troublesome to install and debug. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a two-way unloading device that can flexibly unload materials to both sides, has a wide application range, is simple to install and debug, has a flexible installation position without limitation, and has low space requirements.

[0005] To achieve the above purpose, the utility model proposes the following technical solutions:

[0006] A two-way unloading device includes the following parts:

[0007] A discharge hopper, which is a boat-shaped hopper with an open upper mouth. Both ends in the length direction are provided with symmetrically outwardly inclined end walls, and the inclination angle is 30° - 45°. The end walls in the width direction are higher than the end walls in the length direction, thereby forming two discharge ports at both ends in the length direction.

[0008] A limiting device, which is used to flexibly limit both ends in the length direction of the discharge hopper. A travel switch is provided at the limiting device, and the change of the limiting state at both ends causes the change of the contact state of the travel switch.

[0009] A turning device, which uses a cycloidal pinwheel reducer to provide rotational power to the transmission shaft. The transmission shaft is hinged to the middle position at the bottom of the discharge hopper through a swing link mechanism. The turning device cooperates with the limiting device to realize the bilateral turning of the discharge hopper.

[0010] When the limit device at one end of the discharge hopper fails to function properly, the transmission shaft drives the swing link mechanism to swing towards the other end, driving the discharge hopper to rotate around the other end, causing one end of the discharge hopper to be higher than the other end. When the discharge hopper tilts to a specified angle, the rotation stops, and then discharging can be carried out. After the discharging is completed, the transmission shaft rotates in the opposite direction, driving the discharge hopper to rotate in the reverse direction to return to its original state, and the limit device at one end of the discharge hopper resumes its limiting state.

[0011] A controller is used to receive the signal that the contact state of the travel switch changes and send instructions to the motors of the cycloidal pinwheel speed reducer and the electro-hydraulic push rod. A control panel is provided on the controller, and a manual input terminal is provided on the control panel.

[0012] The bottom bracket provides support for the limit device, the turning device, and the discharge hopper.

[0013] Preferably, the bottom bracket includes a mounting base plate and two groups of limit brackets. Each group of limit brackets includes two oppositely arranged support frames. Limit grooves are provided on the support frames, and the support frames are fixedly arranged on the mounting base plate.

[0014] Three fixed rotating shafts are fixedly arranged at the bottom of the discharge hopper, which are respectively located at both ends and the middle position along the length direction of the bottom of the discharge hopper. The length of the fixed rotating shaft is greater than the width of the bottom of the discharge hopper, and the axis of the fixed rotating shaft is arranged along the width direction of the discharge hopper. The fixed rotating shafts at both ends of the discharge hopper correspond to the limit brackets, and the limit grooves on the two support frames form a placement space for both ends of the fixed rotating shaft. The limit grooves cooperate with the fixed rotating shaft, enabling the fixed rotating shaft to be placed into and removed from the limit groove, and when the fixed shaft is placed in the limit groove, the degree of freedom of the fixed shaft is restricted.

[0015] The limit device includes two groups of limiters, which are symmetrically arranged on the two limit brackets. The limiter includes an electro-hydraulic push rod, a sliding plate, and a travel switch. The travel switch is arranged on one side of the limit groove on the support frame, and the sliding plate is arranged on the other side of the limit groove. The electro-hydraulic push rod applies an external force to the sliding plate, causing the sliding plate to move along the length direction of the discharge hopper. During the movement, the free end of the sliding plate moves away from or touches the travel switch to change the contact state of the travel switch.

[0016] When the sliding plate touches the travel switch, the upper part of the limit groove is closed by the sliding plate, the length of the electro-hydraulic push rod remains unchanged, and the sliding plate maintains the contact relationship with the travel switch. The fixed rotating shaft in the limit groove is in a limited state. When the sliding plate moves away from the travel switch by a certain distance, the limit groove is open, and the fixed rotating shaft in the limit groove is in a state of limit failure, that is, a free state.

[0017] Preferably, the turning device includes a cycloidal pinwheel speed reducer, a transmission shaft, a coupling, a lower connecting rod, an upper connecting rod, and a bearing seat. The base of the cycloidal pinwheel speed reducer is fixed on the mounting base plate. The cycloidal pinwheel speed reducer provides power to the transmission shaft, driving the transmission shaft to rotate bidirectionally at a certain angle. Two bearing seats are respectively arranged on the transmission shaft, and the bearing seats are fixed on the mounting base plate to fix the transmission shaft. The coupling is arranged on the transmission shaft. The transmission shaft is connected to one end of the lower connecting rod through the coupling, and the transmission shaft and the lower connecting rod rotate synchronously. The other end of the lower connecting rod is hinged to one end of the upper connecting rod, and the other end of the upper connecting rod is hinged to the middle position at the bottom of the discharge hopper. The lower connecting rod, the upper connecting rod, and the discharge hopper form a swing link mechanism.

[0018] Preferably, there are two sets of couplings in the turning device, namely a first coupling and a second coupling. The first coupling and the second coupling are symmetrically arranged at both ends of the transmission shaft. The lower connecting rod connected to the first coupling is the first lower connecting rod, the upper connecting rod hinged to the first lower connecting rod is the first upper connecting rod, the lower connecting rod connected to the second coupling is the second lower connecting rod, and the upper connecting rod hinged to the second lower connecting rod is the second upper connecting rod. The first upper connecting rod and the second upper connecting rod are hinged to both ends of the second fixed rotating shaft, and the first upper connecting rod and the second upper connecting rod are symmetrically arranged.

[0019] Preferably, the three fixed rotating shafts are respectively a first fixed rotating shaft, a second fixed rotating shaft, and a third fixed rotating shaft. The second fixed rotating shaft is placed at the middle position at the bottom of the discharge hopper, and the first fixed rotating shaft and the third fixed rotating shaft are placed at both ends in the length direction of the discharge hopper. The first fixed rotating shaft and the third fixed rotating shaft respectively correspond to two sets of limiting brackets.

[0020] Preferably, limiting baffles are arranged at both ends of the first fixed rotating shaft and the third fixed rotating shaft. The distance between the limiting baffles is matched with the distance between the support frames. When the first fixed rotating shaft is placed in the limiting groove, the two limiting baffles enter the inner side of the support frames, further restricting the freedom degree of the discharge hopper in the width direction and increasing the stability of the device.

[0021] Preferably, the stopper further includes a linkage plate and a limiting ring. The limiting ring is arranged on the support frame to further limit the movement range of the sliding plate. One end of the sliding plate passes through the limiting ring as a free end, and the free end of the sliding plate can touch the contact point of the travel switch. Both ends of the linkage plate are connected to the other end of the sliding plate, and the electro-hydraulic push rod is connected to the middle position of the linkage plate. The electro-hydraulic push rod can push the linkage plate to move along the length direction of the discharge hopper, thereby driving the sliding plate to move away from or close to the travel switch.

[0022] Preferably, the electro-hydraulic push rod is arranged inside the limiting bracket. When the electro-hydraulic push rod extends, it will cause the sliding plate to move away from the travel switch. When the electro-hydraulic push rod shortens, it will cause the sliding plate to approach and touch the travel switch.

[0023] Specifically, the two sides of the discharge hopper along the length direction are respectively set as the left side and the right side. The limit bracket on the left side is the first limit bracket, the limiter on the left side is the first limiter, the electro-hydraulic push rod on the left side is the first electro-hydraulic push rod, the travel switch on the left side is the first travel switch, the linkage plate on the left side is the first linkage plate, and the sliding plate on the left side is the first sliding plate.

[0024] The first fixed rotating shaft is located on the left side of the bottom of the discharge hopper, and the third fixed rotating shaft is located on the right side of the bottom of the discharge hopper.

[0025] The limit bracket on the right side is the second limit bracket, the limiter on the right side is the second limiter, the electro-hydraulic push rod on the right side is the second electro-hydraulic push rod, the travel switch on the right side is the second travel switch, the linkage plate on the right side is the second linkage plate, and the sliding plate on the right side is the second sliding plate.

[0026] The first electro-hydraulic push rod is arranged inside the first limit bracket. When the first electro-hydraulic push rod extends, it will cause the first sliding plate to move away from the first travel switch. When the first electro-hydraulic push rod shortens, it will cause the first sliding plate to approach and touch the first travel switch.

[0027] The second electro-hydraulic push rod is arranged inside the second limit bracket. When the second electro-hydraulic push rod extends, it will cause the second sliding plate to move away from the second travel switch. When the second electro-hydraulic push rod shortens, it will cause the second sliding plate to approach and touch the second travel switch.

[0028] When this discharge device is used in cooperation with a belt conveyor or a scraper conveyor, it only needs to be installed at the material dropping place at the tail end of the belt conveyor or below the material dropping port of the scraper conveyor. At the same time, the left and right sides of this discharge device respectively correspond to the left and right storage bins.

[0029] Specifically, in the initial state, the length of the first electro-hydraulic push rod remains unchanged, so that the free end of the first sliding plate remains in contact with the contact of the first travel switch; the length of the second electro-hydraulic push rod remains unchanged, so that the free end of the second sliding plate remains in contact with the contact of the second travel switch, and at the same time, the first lower connecting rod and the second lower connecting rod are synchronously in the left-tilting state.

[0030] When discharging to the right storage bin is required, at this time, enter the right-side discharge instruction on the control panel of the controller. The controller then sends an extension instruction to the first electro-hydraulic push rod, causing the first electro-hydraulic push rod to extend and push the first linkage plate to move to the left, driving the first sliding plate away from the first travel switch, causing the contact state of the first travel switch to change. At this time, the first travel switch sends an electrical signal to the controller. After receiving this electrical signal, the controller sends a forward rotation instruction to the cycloidal pinwheel speed reducer after a certain delay. During this period, the first sliding plate moves a certain distance, causing the first fixed rotating shaft to be released from the restriction of the first sliding plate, and the first fixed rotating shaft returns to the free state.

[0031] The controller is equipped with a program, and a delay time program is set within the program. After receiving the electrical signal from the first travel switch, it delays for a period of time, allowing the first sliding plate to move a sufficient distance, causing the first fixed rotating shaft to fully return to a free state.

[0032] Then the cycloidal pinwheel speed reducer starts to rotate. During the rotation of the cycloidal pinwheel speed reducer, the lower connecting rod drives the upper connecting rod to swing. Since the third fixed rotating shaft is still in a restricted state, the discharge hopper swings around the third fixed rotating shaft. When it rotates a specified angle, the cycloidal pinwheel speed reducer stops rotating, and the discharge hopper is in a state of discharging to the right, that is, the left side of the discharge hopper is higher than the right side. At this time, in cooperation with the belt conveyor or the scraper conveyor, the material falls into the discharge hopper and then into the right silo along the discharge hopper.

[0033] Discharging starts to the right silo. When the amount of material in the right silo is sufficient, the conveyor stops feeding. At this time, a reset command is manually input on the control panel, and the controller sends a reverse rotation command to the cycloidal pinwheel speed reducer. The rotation angle is the same as the forward rotation angle, but the rotation direction is opposite. It starts to reverse rotate. The lower connecting rod drives the upper connecting rod to swing in the opposite direction. Since the third fixed rotating shaft is still in a restricted state, the discharge hopper swings around the third fixed rotating shaft. After the rotation is completed, the left side of the discharge hopper is at the same height as the right side, and the first fixed rotating shaft returns to the limit groove on the first limit bracket.

[0034] At this time, a left limit command is manually input on the control panel, and the controller sends a retraction command to the first electro-hydraulic push rod. The first electro-hydraulic push rod retracts, causing the first linkage plate to move inward, driving the free end of the first sliding plate towards the contact of the first travel switch until the free end of the first sliding plate touches the contact of the first travel switch. At this time, the first travel switch sends a touch signal to the controller, and the controller then sends a stop command to the first electro-hydraulic push rod. The first electro-hydraulic push rod stops moving and keeps its length unchanged, causing the first sliding plate to maintain the touch state with the contact of the first travel switch. Thus, a process of discharging to the right is completed, that is, it returns to the initial state.

[0035] When discharging to the left silo is required, at this time, a left discharge command is input on the control panel of the controller. The controller immediately sends an elongation command to the second electro-hydraulic push rod, causing the second electro-hydraulic push rod to elongate and push the second linkage plate to move to the right, driving the second sliding plate away from the second travel switch, causing the state of the contact of the second travel switch to change. At this time, the second travel switch sends an electrical signal to the controller. After receiving this electrical signal, the controller delays for a certain time and then sends a forward rotation command to the cycloidal pinwheel speed reducer. During this period, the second sliding plate moves a certain distance, releasing the restriction of the third fixed rotating shaft by the second sliding plate, and the third fixed rotating shaft returns to a free state.

[0036] The controller is equipped with a program, and a delay time program is set within the program. After receiving the electrical signal of the second travel switch, it delays for a period of time, enabling the second sliding plate to move a sufficient distance, causing the third fixed rotating shaft to fully return to its free state.

[0037] Then the cycloidal pinwheel speed reducer starts to rotate. During the rotation of the cycloidal pinwheel speed reducer, the lower connecting rod drives the upper connecting rod to swing. Since the first fixed rotating shaft is still in a restricted state, the unloading hopper swings around the first fixed rotating shaft. When it rotates a specified angle, the cycloidal pinwheel speed reducer stops rotating, and the unloading hopper is in a state of discharging to the left, that is, the right side of the unloading hopper is higher than the left side. At this time, in cooperation with the belt conveyor or the scraper conveyor, the material falls into the unloading hopper and then into the left bin along the unloading hopper.

[0038] Discharging starts to the left bin. When the amount of material in the left bin is sufficient, the conveyor stops feeding. At this time, a reset command is manually input on the control panel, and the controller sends a reverse rotation command to the cycloidal pinwheel speed reducer. The rotation angle is the same as the forward rotation angle, but the rotation direction is opposite. It starts to reverse rotate. The lower connecting rod drives the upper connecting rod to swing in the opposite direction. Since the first fixed rotating shaft is still in a restricted state, the unloading hopper swings around the first fixed rotating shaft. After the rotation is completed, the right side of the unloading hopper is as high as the left side, and the third fixed rotating shaft returns to the limit groove on the second limit bracket.

[0039] At this time, a right limit command is manually input on the control panel, and the controller sends a retraction command to the second electro-hydraulic push rod. The second electro-hydraulic push rod retracts, causing the second linkage plate to move inward, driving the free end of the second sliding plate to move towards the contact point of the second travel switch until the free end of the second sliding plate touches the contact point of the second travel switch. At this time, the second travel switch sends a touch signal to the controller, and the controller then sends a stop command to the second electro-hydraulic push rod. The second electro-hydraulic push rod stops moving and keeps its length unchanged, causing the second sliding plate to maintain the touch state with the contact point of the second travel switch. Thus, a process of discharging to the left is completed, that is, it returns to the initial state.

[0040] The above forward rotation direction corresponds to the clockwise direction, and the reverse rotation direction corresponds to the counterclockwise direction.

[0041] The setting of the delay time program in the above-mentioned controller belongs to the existing content in the prior art and is known to those skilled in the art.

[0042] The beneficial effects of the present utility model are as follows:

[0043] Through the unloading hopper, the limiting device and the turning device, the present utility model enables the unloading hopper to flip to both sides, thereby achieving the purpose of discharging to both sides.

[0044] Through the cooperation of the limiting device and the turning device with the discharge hopper, the utility model can realize the flexible turning of the discharge hopper to both sides, and the operation is simple.

[0045] When the utility model is installed, only the bottom bracket needs to be installed at the material dropping place at the tail end of the belt conveyor or under the material dropping port of the scraper conveyor. At the same time, the left and right sides of the discharge hopper respectively correspond to the left and right bins. The installation position is flexible and not restricted, and it can be installed at any time as needed, with low space requirements.

[0046] The utility model controls the limiting device and the turning device through a controller, thereby realizing the automatic turning and automatic reset of the discharge hopper, without redundant manual operation, with high automation degree, saving labor cost and time cost, and high efficiency.

[0047] Adopting the above scheme, the utility model can discharge materials flexibly to both sides, with a wide application range, simple installation and commissioning, flexible installation position without restriction, and low space requirements. Description of the Drawings

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0059] As Figure 1 shown, a two-way discharging device includes the following parts:

[0060] The discharging hopper 1 is a boat-shaped hopper with an open upper mouth. At both ends in the length direction, there are symmetrically arranged end walls that slope outward, with an inclination angle of 30° to 45°. The end walls in the width direction are higher than the end walls in the length direction, thereby forming two discharging openings at both ends in the length direction.

[0061] The limiting device is used to flexibly limit both ends of the discharging hopper 1 in the length direction. A travel switch is provided at the limiting device, and a change in the limiting state at both ends causes a change in the contact state of the travel switch.

[0062] The turning device uses a cycloidal pinwheel reducer 3 to provide rotational power to the transmission shaft 30. The transmission shaft 30 is hinged to the middle position at the bottom of the discharging hopper 1 through a swing link mechanism. The turning device cooperates with the limiting device to achieve bilateral turning of the discharging hopper 1.

[0063] The controller is used to receive the signal of the change in the contact state of the travel switch and send instructions to the cycloidal pinwheel reducer 3 and the motor of the electro-hydraulic push rod. A control panel is provided on the controller, and a manual input terminal is provided on the control panel.

[0064] The bottom bracket provides support for the limiting device, the turning device, and the discharging hopper.

[0065] The bottom bracket includes a mounting base plate 43 and two groups of limiting brackets, namely the first limiting bracket 42 and the second limiting bracket 41. Each group of limiting brackets includes two oppositely arranged support frames. A limiting groove is provided on the support frame, and the support frame is fixedly arranged on the mounting base plate 43.

[0066] Three fixed rotating shafts are fixedly arranged at the bottom of the discharging hopper 1, respectively at both ends and the middle position along the length direction of the bottom of the discharging hopper 1. The length of the fixed rotating shaft is greater than the width of the bottom of the discharging hopper 1. The axis of the fixed rotating shaft is arranged along the width direction of the discharging hopper 1. The fixed rotating shafts at both ends of the discharging hopper 1 correspond to the limiting brackets. The limiting grooves on the two support frames form a placement space for both ends of the fixed rotating shaft. The limiting groove cooperates with the fixed rotating shaft, enabling the fixed rotating shaft to be placed into and taken out of the limiting groove, and restricting the degree of freedom of the fixed shaft when it is placed in the limiting groove.

[0067] The limiting device includes two groups of limiters, symmetrically arranged on the two limiting brackets. The limiter includes an electro-hydraulic push rod, a sliding plate, and a travel switch. The travel switch is arranged on one side of the limiting groove on the support frame, and the sliding plate is arranged on the other side of the limiting groove. The electro-hydraulic push rod applies an external force to the sliding plate, causing the sliding plate to move along the length direction of the discharging hopper. During the movement, the free end of the sliding plate moves away from or touches the travel switch to change the contact state of the travel switch.

[0068] When the sliding plate touches the travel switch, the upper part of the limit groove is closed by the sliding plate, the length of the electro-hydraulic push rod remains unchanged, the sliding plate maintains the touching relationship with the travel switch, and the fixed rotating shaft in the limit groove is in a limited state; when the sliding plate moves away from the travel switch by a certain distance, the limit groove opens, and the fixed rotating shaft in the limit groove is in a state of ineffective limit, that is, a free state.

[0069] As Figure 3 shown, the turning device includes a cycloid pinwheel speed reducer 3, a transmission shaft 30, a coupling 31, a lower connecting rod, an upper connecting rod and a bearing seat. The base of the cycloid pinwheel speed reducer 3 is fixed on the mounting base plate 43. The cycloid pinwheel speed reducer 3 provides power to the transmission shaft 30 to drive the transmission shaft 30 to rotate bidirectionally by a certain angle; two bearing seats are separately arranged on the transmission shaft 30, and the bearing seats are fixed on the mounting base plate 43 to realize the fixation of the transmission shaft 30; the coupling 31 is arranged on the transmission shaft 30, and the transmission shaft 30 is connected to one end of the lower connecting rod through the coupling 31. The transmission shaft 30 and the lower connecting rod rotate synchronously. The other end of the lower connecting rod is hinged to one end of the upper connecting rod, and the other end of the upper connecting rod is hinged to the middle position at the bottom of the discharge hopper 1. The lower connecting rod, the upper connecting rod and the discharge hopper 1 form a swinging link mechanism.

[0070] The three groups of fixed rotating shafts are respectively a first fixed rotating shaft 121, a second fixed rotating shaft 111 and a third fixed rotating shaft 101. The second fixed rotating shaft 111 is placed at the middle position at the bottom of the discharge hopper 1, and the first fixed rotating shaft 121 and the third fixed rotating shaft 101 are placed at both ends in the length direction of the discharge hopper 1. The first fixed rotating shaft 121 and the third fixed rotating shaft 101 respectively correspond to the first limit bracket 42 and the first limit bracket 41.

[0071] There are two groups of couplings 31 in the turning device, namely a first coupling and a second coupling. The first coupling and the second coupling are symmetrically arranged at both ends of the transmission shaft 30. The lower connecting rod connected to the first coupling is a first lower connecting rod 32, the upper connecting rod hinged to the first lower connecting rod 32 is a first upper connecting rod 33, the lower connecting rod connected to the second coupling is a second lower connecting rod 36, and the upper connecting rod hinged to the second lower connecting rod 36 is a second upper connecting rod 37. The first upper connecting rod 33 and the second upper connecting rod 37 are hinged to both ends of the second fixed rotating shaft 111, and the first upper connecting rod 33 and the second upper connecting rod 37 are symmetrically arranged.

[0072] Limit baffles are arranged at both ends of the first fixed rotating shaft 121 and the third fixed rotating shaft 101. The distance between the limit baffles is matched with the distance between the support frames. When the first fixed rotating shaft 121 is placed in the limit groove, the two limit baffles enter the inner side of the support frames, further restricting the freedom degree of the discharge hopper 1 in the width direction and increasing the stability of the device.

[0073] The stopper further includes a linkage plate and a limit ring. The limit ring is arranged on the support frame to further limit the movement range of the sliding plate. One end of the sliding plate passes through the limit ring and is the free end, and the free end of the sliding plate can touch the contact of the travel switch. Both ends of the linkage plate are connected to the other end of the sliding plate, and the electro-hydraulic push rod is connected to the middle position of the linkage plate. The electro-hydraulic push rod can push the linkage plate to move along the length direction of the discharge hopper 1, thereby driving the sliding plate to move away from or close to the travel switch for contact.

[0074] The electro-hydraulic push rod is arranged inside the limit support. When the electro-hydraulic push rod extends, it will cause the sliding plate to move away from the travel switch, and when the electro-hydraulic push rod shortens, it will cause the sliding plate to move closer to and touch the travel switch.

[0075] Specifically, as Figures 1 - 3 shown, the two sides of the discharge hopper 1 along the length direction are respectively set as the left side and the right side. The limit support on the left side is the first limit support 42, the stopper on the left side is the first stopper, the electro-hydraulic push rod on the left side is the first electro-hydraulic push rod 21, the travel switch on the left side is the first travel switch 212, the linkage plate on the left side is the first linkage plate 211, and the sliding plate on the left side is the first sliding plate.

[0076] The first fixed rotating shaft 121 is located on the left side of the bottom of the discharge hopper 1, and the third fixed rotating shaft 101 is located on the right side of the bottom of the discharge hopper 1.

[0077] The limit support on the right side is the second limit support 41, the stopper on the right side is the second stopper, the electro-hydraulic push rod 22 on the right side is the second electro-hydraulic push rod, the travel switch on the right side is the second travel switch 222, the linkage plate on the right side is the second linkage plate 221, and the sliding plate on the right side is the second sliding plate.

[0078] The first electro-hydraulic push rod 21 is arranged inside the first limit support 42. When the first electro-hydraulic push rod 21 extends, it will cause the first sliding plate to move away from the first travel switch 212, and when the first electro-hydraulic push rod 21 shortens, it will cause the first sliding plate to move closer to and touch the first travel switch 212.

[0079] The second electro-hydraulic push rod 22 is arranged inside the second limit support 41. When the second electro-hydraulic push rod 22 extends, it will cause the second sliding plate to move away from the second travel switch 222, and when the second electro-hydraulic push rod 22 shortens, it will cause the second sliding plate to move closer to and touch the second travel switch 222.

[0080] When this discharging device is used in cooperation with a belt conveyor or a scraper conveyor during use, it needs to be installed at the material dropping position at the tail end of the belt conveyor or below the material dropping port of the scraper conveyor. At the same time, the left and right sides of this discharging device respectively correspond to the left and right storage bins.

[0081] Specifically, in the initial state, the length of the first electro-hydraulic push rod 21 remains unchanged, so that the free end of the first sliding plate remains in contact with the contact of the first travel switch 212; the length of the second electro-hydraulic push rod 22 remains unchanged, so that the free end of the second sliding plate remains in contact with the contact of the second travel switch 222, and at the same time, the first lower connecting rod 32 and the second lower connecting rod 36 are synchronously in the left-tilting state.

[0082] When it is necessary to unload materials into the right bin, at this time, a right-side unloading instruction is input on the control panel of the controller. The controller then sends an elongation instruction to the first electro-hydraulic push rod 21, causing the first electro-hydraulic push rod 21 to elongate and push the first linkage plate 211 to move to the left, driving the first sliding plate away from the first travel switch 212, causing the contact state of the first travel switch 212 to change. At this time, the first travel switch 212 sends an electrical signal to the controller. After receiving this electrical signal, the controller sends a forward rotation instruction to the cycloid pinwheel speed reducer 3 after a certain delay. During this period, the first sliding plate moves a certain distance, causing the first fixed rotating shaft 121 to be released from the restriction of the first sliding plate, and the first fixed rotating shaft 121 returns to the free state.

[0083] The controller is equipped with a program, and a delay time program is set in the program. After receiving the electrical signal from the first travel switch 212, it is delayed for a period of time, so that the first sliding plate moves a sufficient distance, causing the first fixed rotating shaft 121 to completely return to the free state.

[0084] Then the cycloid pinwheel speed reducer 3 starts to rotate. During the rotation of the cycloid pinwheel speed reducer 3, the lower connecting rod drives the upper connecting rod to swing. Since the third fixed rotating shaft 101 is still in the restricted state, the unloading hopper 1 swings around the third fixed rotating shaft 101. When it rotates a specified angle, the cycloid pinwheel speed reducer 3 stops rotating, and the unloading hopper 1 is in the state of unloading to the right, that is, the left side of the unloading hopper 1 is higher than the right side. At this time, in cooperation with the belt conveyor or the scraper conveyor, the materials fall into the unloading hopper 1 and fall into the right bin along the unloading hopper 1.

[0085] As Figure 5 shown, when starting to unload materials into the right bin, when the amount of materials in the right bin is sufficient, the conveyor stops feeding. At this time, a reset instruction is manually input on the control panel. The controller sends a reverse rotation instruction to the cycloid pinwheel speed reducer 3. The rotation angle is the same as the forward rotation angle, but the rotation direction is opposite. It starts to reverse, and the lower connecting rod drives the upper connecting rod to swing in the opposite direction. Since the third fixed rotating shaft 101 is still in the restricted state, the unloading hopper 1 swings around the third fixed rotating shaft 101. After the rotation is completed, the left side of the unloading hopper 1 is as high as the right side, and the first fixed rotating shaft 121 returns to the limit groove on the first limit bracket 42.

[0086] At this time, manually input the left limit instruction to the control panel. The controller sends a retraction instruction to the first electro-hydraulic push rod 21. The first electro-hydraulic push rod 21 retracts, causing the first linkage plate 211 to move inward, driving the free end of the first sliding plate to move towards the contact of the first travel switch 212 until the free end of the first sliding plate touches the contact of the first travel switch 212. At this time, the first travel switch 212 sends a touch signal to the controller, and the controller then sends a stop instruction to the first electro-hydraulic push rod 21. The first electro-hydraulic push rod 21 stops moving and its length remains unchanged, causing the first sliding plate to maintain the touch state with the contact of the first travel switch 212. Thus, a process of discharging to the right is completed, that is, it returns to the initial state.

[0087] When it is necessary to discharge materials to the left bin, at this time, input the left discharge instruction on the control panel of the controller. The controller immediately sends an extension instruction to the second electro-hydraulic push rod 22, causing the second electro-hydraulic push rod 22 to extend and push the second linkage plate 221 to move to the right, driving the second sliding plate away from the second travel switch 222, causing the contact state of the second travel switch 222 to change. At this time, the second travel switch 222 sends an electrical signal to the controller. After receiving this electrical signal, the controller sends a forward rotation instruction to the cycloid pinwheel speed reducer 3 after a certain delay. During this period, the second sliding plate moves a certain distance, enabling the third fixed rotating shaft 101 to be released from the restriction of the second sliding plate, and the third fixed rotating shaft 101 returns to a free state.

[0088] Then the cycloid pinwheel speed reducer 3 starts to rotate. During the rotation of the cycloid pinwheel speed reducer 3, the lower connecting rod drives the upper connecting rod to swing. Since the first fixed rotating shaft 121 is still in a restricted state, the discharge hopper 1 swings around the first fixed rotating shaft 121. When it rotates a specified angle, the cycloid pinwheel speed reducer 3 stops rotating, and the discharge hopper 1 is in a state of discharging to the left, that is, the right side of the discharge hopper 1 is higher than the left side. At this time, in cooperation with the belt conveyor or the scraper conveyor, materials fall into the discharge hopper 1 and then fall into the left bin along the discharge hopper 1.

[0089] As Figure 4 shown, when starting to discharge materials to the left bin, when the amount of materials in the left bin is sufficient, the conveyor stops feeding. At this time, manually input the reset instruction on the control panel. The controller sends a reverse rotation instruction to the cycloid pinwheel speed reducer 3. The rotation angle is the same as the forward rotation angle, but the rotation direction is opposite. It starts to reverse. The lower connecting rod drives the upper connecting rod to swing in the opposite direction. Since the first fixed rotating shaft 121 is still in a restricted state, the discharge hopper 1 swings around the first fixed rotating shaft 121. After the rotation is completed, the right side of the discharge hopper 1 is as high as the left side, and the third fixed rotating shaft 101 returns to the limit groove on the second limit bracket 41.

[0090] At this time, a right limit instruction is manually input to the control panel, and the controller sends a retraction instruction to the second electro-hydraulic push rod 22. The second electro-hydraulic push rod 22 retracts, causing the second linkage plate 221 to move inward, driving the free end of the second sliding plate to move towards the contact of the second travel switch 222 until the free end of the second sliding plate touches the contact of the second travel switch 222. At this time, the second travel switch 222 sends a touch signal to the controller, and the controller then sends a stop instruction to the second electro-hydraulic push rod 22. The second electro-hydraulic push rod 22 stops moving and its length remains unchanged, causing the second sliding plate to maintain the touch state with the contact of the second travel switch 222. Thus, a process of discharging to the left is completed, that is, it returns to the initial state.

[0091] The above forward rotation direction corresponds to the clockwise direction, and the reverse rotation direction corresponds to the counterclockwise direction.

[0092] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
