[0002] At a bulk cargo terminal, a forked hopper is a device that enables the belt conveyor system to transport bulk materials through different paths for production operations.

[0003] The traditional bifurcated funnel rotates the power arm by the extension and retraction of the electric push rod, thereby driving the shaft to rotate, and then the shaft drives the flap to rotate along the shaft to achieve the reversal of the bifurcated funnel, so that the bulk materials can pass through different paths. However, this type of bifurcated funnel uses the torque of the shaft to drive the flap to rotate. The shaft is subject to a large force, especially in low temperature working conditions. The flap is easy to freeze. When the shaft is subjected to excessive force, it will cause the shaft key to break, increasing maintenance costs. Summary of the invention

[0036] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0037] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "connected" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0038] It should be noted that the bifurcated funnel mechanism of bulk terminal unloaders in extremely cold countries and regions has not had a heating function. As a result, under severe winter conditions (extreme minimum temperature of -20°C or below), the moisture between the materials (ore) freezes due to the low temperature, which can easily cause the bifurcated funnel wall and the inner flap of the funnel to get stuck, resulting in the flap being unable to flip flexibly.

[0039] In view of the above-mentioned defects, the present invention proposes a solution for installing a heating device in the forked funnel of a ship unloader. The funnel wall is heated to thaw and loosen the frozen materials in the gap between the funnel wall and the flap through heat transfer, thereby enabling the flap to work normally.

[0040] The forked funnel of a ship unloader according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0041] According to the embodiment of the present invention, the ship unloader bifurcated funnel with heating function is as follows: Figure 1-Figure 3 As shown, the forked funnel housing 10 , a turning shaft 20 , a turning plate 30 , a driving rod 40 , a driving assembly 50 and a heating device 60 may be included.

[0042] An arc-shaped through groove 11 is formed on one side surface of the bifurcated funnel shell 10 .

[0043] The turning shaft 20 is installed at the bifurcation node inside the bifurcation funnel housing 10 .

[0044] The flap 30 is disposed inside the bifurcated funnel housing 10 and the bottom of the flap 30 is connected to the flip shaft 20 . The flap 30 flips inside the bifurcated funnel housing 10 via the flip shaft 20 .

[0045] The driving rod 40 is inserted into the through slot 11 , and one end of the driving rod 40 extends into the interior of the bifurcated funnel housing 10 to connect with the flap 30 .

[0046] The driving assembly 50 is disposed outside the bifurcated funnel housing 10 , and the driving assembly 50 is connected to the other end of the driving rod 40 extending out of the bifurcated funnel housing 10 to drive the driving rod 40 to move in an arc direction in the through slot 11 .

[0047] The heating device 60 is evenly installed on the outer wall of the bifurcated funnel shell 10 , and the heating device 60 is used to adjust and monitor the temperature of the outer wall of the bifurcated funnel shell 10 in real time.

[0048] The ship unloader bifurcated funnel with heating function according to the embodiment of the present invention drives the driving rod 41 through the driving assembly 50 to drive the driving rod 41 to move along an arc track in the through slot 11 of the bifurcated funnel shell 10, and then the driving rod 41 drives the flap 30 to rotate around the flip shaft 20 inside the bifurcated funnel shell 10 to achieve the reversal of the ship unloader bifurcated funnel. The driving rod 41 drives the flap 30 to flip along the arc track, which increases the rotational torque of the flap 30 compared to the conventional bifurcated funnel, effectively solves the problem that the torque of the flip shaft 20 is too large, resulting in the fracture of the shaft key in the flip shaft 20, improves the reliability and durability of the flip shaft 20, and reduces the replacement and maintenance costs.

[0049] In addition, a heating device 60 is installed on the outer wall of the forked funnel shell 10, so that in severe cold working conditions with low temperatures, the heating device 60 can be activated to prevent the material between the inner wall of the forked funnel shell 10 and the gap between the flap 30 from freezing, thereby reducing the influence of the force torque on the flip shaft 20 when it rotates, and further improving the service life of the flip shaft 20.

[0050] In some embodiments, Figure 1 As shown, a through groove 11 is provided on the side surface of the bifurcated funnel housing 10 along the length direction.

[0051] The through slot 11 is located at the upper half of the side surface of the bifurcated funnel housing 10 , and the arc center of the arc-shaped through slot 11 is located in the axial direction of the flip shaft 20 .

[0052] Thus, the through slot 11 is provided along the length direction of the bifurnace shell 10, and the flap 30 can be flipped along the plane where the length direction of the bifurnace shell 10 is located under the drive of the driving rod 40 in the through slot 11. The through slot 11 is provided at the upper half of the side surface of the bifurnace shell 10, so that when the driving rod 40 is connected to the flap 30, the flap 30 itself forms a longer force arm, and the driving rod 40 only needs to apply a smaller force when driving, which greatly saves the energy consumption of the driving assembly 50.

[0053] In addition, the arc center of the arc-shaped through groove 11 is located in the axial direction of the flip axis 20 , which can greatly ensure the energy efficiency of the driving component 50 and also ensure the smoothness of the driving rod 40 driving the flap 30 to flip around the flip axis 20 .

[0054] In some embodiments, Figure 1 As shown, the turning axis 20 is arranged along the width direction of the bifurcated funnel housing 10 .

[0055] Thus, the flap 30 rotates along the plane where the length direction of the bifurcated funnel shell 10 is located, and does not interfere with the side wall of the bifurcated funnel shell 10 .

[0056] In some embodiments, the driving rod 40 is disposed perpendicular to the through slot 11 and penetrates the through slot 11 .

[0057] As a result, on the one hand, the driving rod 40 is prevented from interfering when moving in the through slot 11 , and on the other hand, the conversion efficiency of the output power of the driving assembly 50 can be maximized.

[0058] In some embodiments, Figure 1 and Figure 2 As shown, the driving assembly 50 may include: a mounting frame 51 , an arc-shaped rack 52 and a driving motor 53 .

[0059] The mounting frame 51 is disposed on the outer side of the bifurcated funnel housing 10 near the through slot 11 .

[0060] The arc-shaped rack 52 is connected to the mounting frame 51 , and the arc-shaped rack 52 is located above the through slot 11 .

[0061] The driving motor 53 is disposed at one end of the driving rod 40 extending out of the bifurcated funnel housing 10 . The output end of the driving motor 53 is connected to a gear 54 , which meshes with the arc-shaped rack 52 .

[0062] That is to say, a mounting frame 51 is provided on one side of the forked funnel shell 10 near the through groove 11, and an arc-shaped rack 52 is connected to the mounting frame 51 corresponding to the position of the through groove 11, and a driving motor 53 is provided at one end of the driving rod 40 extending out of the forked funnel shell 10, and the gear 54 on the driving motor 53 engages with the arc-shaped rack 52, and then the driving motor 53 drives the driving rod 40 to move along the arc-shaped rack 52, which is stable, reliable and easy to maintain.

[0063] The arc-shaped rack 52 is disposed above the through slot 11 , so that when the gear 54 on the driving motor 53 rotates along the arc-shaped rack 52 , the driving rod 40 is driven to move more smoothly.

[0064] In some embodiments, Figure 1 As shown, the arc center of the arc-shaped rack 52 is located in the axial direction of the tilting shaft 20 .

[0065] Therefore, when the gear 54 on the driving motor 53 rotates along the arc-shaped rack 52, it can drive the driving rod 40 to rotate at the same angular velocity, making the driving more efficient.

[0066] In some embodiments, the teeth of the arc-shaped rack 52 face downward.

[0067] As a result, the driving motor 53 and the driving rod 40 connected thereto are subjected to forces in two opposite radial directions during movement, and thus operate more smoothly.

[0068] In some embodiments, the driving motor 53 further includes a reducer.

[0069] That is to say, the output power of the driving motor 53 is controlled by the speed reducer, thereby adjusting the speed at which the gear 54 rotates along the arc-shaped rack 52 .

[0070] In some embodiments, Figure 3 As shown, the heating device 60 may include a plurality of electric heating blocks 61 , and the plurality of electric heating blocks 61 are evenly attached to the outer wall of the bifurcated funnel housing 10 .

[0071] That is to say, by evenly distributing a plurality of electric heating blocks 61 on the outer wall of the forked funnel shell 10, the interior thereof is heated, so as to solve the problem that the inner wall of the forked funnel shell 10 and the inner flap 30 of the bucket are frozen and stuck in severe cold working conditions, resulting in the flap 30 being unable to flip flexibly and damaging the shaft key of the flip shaft 20.

[0072] As an example, the electric heating block 61 is made of cast copper (aluminum), with a tubular electric heating element as the heating element, and a high-quality copper (aluminum alloy) material as the shell. The electric heater is formed by pressure (casting). Its use temperature is generally between 150 and 350 degrees Celsius. The cast aluminum and cast copper electric heating elements adopt a special frequency conversion structure, with a larger heat transfer surface, long life, uniform heating, strong mechanical properties, corrosion resistance and other advantages. The electric heating block 61 with high efficiency and uniform heating is arranged around the bifurcated funnel shell 10 and near the root of the flip axis 20. The electric heating block 61 has a temperature control device inside, which can control the maximum surface temperature of the electric heating block 61 within a predetermined range. The back of the heating block has PSA glue (pressure sensitive adhesive) to firmly bond the heating block to the inner wall of the bifurcated funnel shell 10. The electric heating blocks 61 arranged on each side of the bifurcated funnel shell 10 are grouped separately, and the parallel structure design is adopted between each electric heating block 61. If there is a problem with one electric heating block 61, the entire system will not be paralyzed. Heat-insulating materials are installed outside the heating surface of the electric heating block 61 to prevent the heat loss of the heating block. Colored steel plates or galvanized plates are installed on the outer layer of the entire electric heating block and the heat-insulating materials to play a protective role.

[0073] In some embodiments, Figure 3 As shown, the heating device 60 may further include a plurality of temperature sensors 62 , and the plurality of temperature sensors 62 are mounted on the outer wall of the bifurcated funnel housing 10 corresponding to the electric heating blocks 61 .

[0074] That is to say, a temperature sensor 62 is installed on the outer wall of the forked funnel shell 10 corresponding to the electric heating block 61 to monitor the temperature of a specific area of ​​the forked funnel shell 10, and then transmit real-time data to an external controller. The controller analyzes the received data and controls the operation of the electric heating block 61 to heat the internal area of ​​the forked funnel shell 10, which is convenient and efficient.

[0075] As an example, the temperature sensor 62 is installed on the outer side wall of the forked funnel flap to detect the temperature of the outdoors and the forked funnel shell 10. When the temperature sensor 62 detects that the temperature is lower than the set temperature, the heating device 60 starts heating. When the temperature is detected to be higher than the specified temperature, the heating device 60 stops heating.

[0076] In addition, the ship unloader bifurcated funnel of the embodiment of the present invention is also provided with an electric heating system electrical control cabinet, which is used to control the operation and stop of the entire heating device 60. The control cabinet is equipped with electrical components required for the electrical control of the entire heating device 60, including air circuit breakers, contactors, solid-state relays, intermediate relays and their auxiliary contacts, and the panel outside the cabinet is equipped with a thermostat instrument (i.e., a temperature controller), start and stop buttons, power indicator lights, operation indicator lights, fault alarm indicator lights and stop indicator lights. Among them, the electric heating system controls the temperature of the electric heating block 61 through the thermostat instrument. For example, the thermostat instrument can adopt an artificial intelligence temperature control instrument, which can set, adjust and detect the real-time temperature of the electric heating block 61. The temperature control instrument adopts a universal wide voltage power supply, has a 50Hz / 60Hz power supply frequency and ℃ / F unit selection function, has a self-tuning function (AT) and an AI artificial intelligence adjustment algorithm, and can quickly complete PID (proportional, integral, derivative) parameter adjustment and self-tuning without the traditional AT oscillation control.

[0077] The electrical control principle of the electric heating system of the heating device 60 is as follows: Figure 4 shown.

[0078] 201 is the main power supply of the electric heating system, a three-phase five-wire system, which supplies power to the main power circuit and control circuit of the electric heating system.

[0079] 202 is the circuit breaker of the main power supply, which is used to switch the main power supply of the power circuit on and off.

[0080] 203 is the contactor of the main power supply, which controls the on and off of the main power supply circuit. When the start button of the electric heating system is turned on, the contactor coil is energized, the contacts are closed, and the main power supply is turned on to supply power to the heating plate.

[0081] 204 is a solid-state relay, which is used to detect the short circuit, overload and overheat protection of the three-phase current of the main circuit. 205 is an electric heating plate, which is made of cast copper (aluminum) to heat the wall of the bifurcated funnel shell.

[0082] 206 is a control power circuit breaker, which is used to provide control power to the electric heating system.

[0083] 207 is the emergency stop button of the electric heating system, which is used to cut off the control power circuit in special emergency situations.

[0084] 208 is a button for stopping the electric heating system. When this button is triggered, the electric heating system stops running.

[0085] 209 is the electric heating system start-up button. When this button is triggered, the electric heating system starts to operate.

[0086] 210 and 211 are temperature controllers used to set, detect and adjust the working temperature of the electric heater system.

[0087] 212 is the fault alarm signal of the electric heating system. After high temperature, overtemperature and main power circuit breaker are turned off, the fault of the electric heating system is detected.

[0088] 213 is the electric heating system operation indicator light, which is used to indicate the system operation status.

[0089] 214 is a power indicator light, which is used to indicate whether the power is turned on or off.

[0090] 215 is a high temperature alarm relay. When this relay is triggered, an alarm signal is given to indicate that the system is at high temperature.

[0091] 217 is the over-temperature fault alarm relay. When this relay is triggered, an alarm signal is given to indicate that the system is over-temperature.

[0092] 216 and 218 are temperature sensors installed on the electric heating block, which are used to detect the temperature of the bifurcated funnel shell wall in real time and transmit the temperature signal to the temperature controllers 210 and 211.

[0093] 219 is the fault alarm indicator light. When the electric heating system is at high temperature, overheated, or the power switch is turned off, the alarm indicator light prompts a system fault alarm.

[0094] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
