[0030] When using a bulk loader for unloading, the telescopic section of the discharger often needs to be extended and then retracted after unloading is complete. Currently, the extension and retraction of the telescopic section of the discharger is controlled by the retraction and extension of a traction rope connected to the lower end of the telescopic section. The traction rope is retracted and extended by a driving member driving a winding reel on a transmission member. Simultaneously, the retraction distance can be controlled by starting and stopping the driving member. Starting and stopping are achieved through electrical signals generated by a trigger member mounted on the transmission member and two inductive travel switches.

[0031] However, in actual operation, the trigger member will generate vibration when it moves along the axial direction of the transmission member. At this time, two electrical signals will be generated simultaneously between the trigger member and the two inductive travel switches, which will cause the bulk loader to work abnormally and even freeze.

[0032] In order to solve the above problems, the present invention proposes a bulk loader, which aims to solve the problem that the existing bulk loader adopts an inductive travel switch that easily generates erroneous control signals, thereby causing the bulk loader to work abnormally.

[0033] like Figures 1 to 3 In one embodiment, the bulk loader includes a bulk material bin 10, a discharge member 20, a drive assembly 30 and a switch assembly 40. The discharge member 20 has a telescopic section 21. The discharge member 20 is connected to the bottom of the bulk material bin 10. The discharge member 20 has a contracted state and a discharge state. The drive assembly 30 includes a drive member 31, a transmission member 32 and two first traction members 33. The transmission member 32 includes a transmission shaft 321 and two winding wheels 322. The drive member 31 is driven and connected to the transmission shaft 321. The two winding wheels 322 are installed on At both axial ends of the transmission shaft 321, one end of the two first traction members 33 is wound around the two winding wheels 3221, and the other ends of the two first traction members 33 are connected to the end of the telescopic section 21 away from the bulk material silo 10. The switch assembly 40 includes a first travel switch 41, a second travel switch 42 and a trigger member 43. The first travel switch 41 and the second travel switch 42 are arranged at intervals along the axial direction of the transmission shaft 321, and the trigger member 43 is threadedly connected to the transmission shaft 321 so as to move axially under the drive of the transmission shaft 321.

[0034] In this embodiment, the discharge member 20 is a cylindrical component with a hollow interior. The end of the discharge member 20 close to the bulk bin 10 is a telescopic section 21. The discharge member 20 can change its own length by extending and retracting the telescopic section 21. The driving member 31 can be a driving motor or a driving motor, which is connected to one end of the transmission shaft 321 and converts the power generated by itself into the rotation of the transmission shaft 321, thereby driving the two winding wheels 322 to rotate. When the driving member 31 drives the transmission shaft 321 and the two winding wheels 322 to rotate clockwise, the two first traction members 33 gradually wind away from the two winding wheels 322. The first traction member 33 is a steel wire rope. As the length of the two first traction members 33 winding away from the two winding wheels 322 gradually increases, the two first traction members 33 gradually wind away from the two winding wheels 322. 33 drives the movable end of the telescopic section 21 to extend; at the same time, due to the rotation of the transmission shaft 321, the trigger member 43 threadedly connected to the transmission shaft 321 moves along the axial direction of the transmission shaft 321, gradually approaching the first travel switch 41. When the trigger member 43 abuts against the contact of the first travel switch 41, the driving member 31 stops working. At this time, the first traction member 33 drives the telescopic section 21 to extend to its maximum length, thereby moving the discharge port of the discharge member 20 to the designated discharge position. At this time, the discharge member 20 is in the discharge state;

[0035] When the driving member 31 drives the transmission shaft 321 and the two winding wheels 322 to rotate counterclockwise, the two first traction members 33 are gradually wound around the first winding grooves 3221 of the two winding wheels 322. As the length of the two first traction members 33 wound around the two winding wheels 322 gradually increases, the two first traction members 33 drive the movable end of the telescopic section 21 to retract; at the same time, due to the rotation of the transmission shaft 321, the trigger member 43 threadedly connected to the transmission shaft 321 moves along the axial direction of the transmission shaft 321, gradually approaching the second travel switch 42. When the trigger member 43 abuts against the contact of the second travel switch 42, the driving member 31 stops working. At this time, the first traction member 33 drives the telescopic section 21 to complete the retraction, thereby causing the discharge port of the discharge member 20 to move to the starting position. At this time, the discharge member 20 is in a retracted state.

[0036] The bulk loader includes a bulk material bin 10, a discharge piece 20, a drive assembly 30 and a switch assembly 40. When the discharge piece 20 needs to extend, the drive piece 31 drives the transmission piece 32 to rotate clockwise or counterclockwise, the first traction piece 33 winds around the winding wheel 322 and drives the discharge piece 20 to extend, and at the same time the trigger piece 43 moves along the axial direction of the transmission shaft 321 until it abuts against the first travel switch 41, so that the drive piece 31 stops working and the transmission piece 32 stops rotating; when the discharge piece 20 needs to retract, the drive piece 31 drives the transmission piece 32 to rotate counterclockwise or clockwise, the first traction piece 33 is wound around the winding wheel 322 and drives the discharge piece 20 to retract, and at the same time the trigger piece 43 moves along the axial direction of the transmission shaft 321 until it abuts against the second travel switch 42, so that the drive piece 31 stops working and the transmission piece 32 stops rotating. This technical solution uses a mechanical travel switch to control the bulk loader, thereby ensuring that a single control signal is generated between the travel switch and the trigger member 43, thereby ensuring the normal operation of the bulk loader and increasing its service life.

[0037] like Figures 1 to 3 In one embodiment, the abutment member 432 includes a mounting plate 4321 and an abutment plate 4322. The mounting plate 4321 is mounted on the side of the main body 431 parallel to the axial direction of the transmission shaft 321, and the abutment plate 4322 is mounted on the side of the mounting plate 4321 parallel to the radial direction of the transmission shaft 321 to abut against the first limit switch 41 or the second limit switch 42.

[0038] In this embodiment, the trigger member 43 includes a main body 431 and two abutting members 432. The main body 431 is the main part of the trigger member 43, which is connected to the transmission shaft 321 and moves as the transmission shaft 321 rotates. The abutments 432 are components installed on both sides of the main body 431. They are arranged on both sides of the main body 431 along the radial direction of the transmission shaft 321. At the same time, the first travel switch 41 and the second travel switch 42 are correspondingly arranged on both sides of the radial direction of the transmission shaft 321. The positions of the first travel switch 41 and the second travel switch 42 correspond to the two abutments 432, so that when the transmission shaft 321 rotates, the abutments 432 can contact the first travel switch 41 and the second travel switch 42. When the abutments 432 contact the first travel switch 41, the unloading part 20 enters the unloading state; when the abutments 432 contact the second travel switch 42, the unloading part 20 enters the contracted state. Through the contact between the abutments 432 and the first travel switch 41 and the second travel switch 42, the state of the unloading part 20 can be accurately controlled to avoid misoperation. At the same time, the abutments 432 is a metal plate with a relatively simple structure and is easy to manufacture and maintain.

[0039] In addition, by arranging the first travel switch 41 and the second travel switch 42 on two different sides, the abutting member 432 can not contact the two travel switches at the same time, which can prevent the state of the unloading member 20 from being accurately controlled, and thus the safety of the bulk machine is improved.

[0040] As Figures 1 to 3 In an embodiment, the transmission shaft 321 is provided with a threaded segment 3211 along the axial direction of the transmission shaft 321, and the main body 431 is provided with a threaded hole corresponding to the threaded segment 3211. When the transmission shaft 321 rotates, the main body 431 moves axially along the threaded segment 3211, so that the abutting plate 4322 is close to or away from the first travel switch 41 or the second travel switch 42.

[0041] In the embodiment, the transmission shaft 321 is provided with a threaded segment 3211 along the axial direction of the transmission shaft 321, and the main body 431 is provided with a threaded hole corresponding to the threaded segment 3211. When the transmission shaft 321 rotates, the threaded connection between the transmission shaft 321 and the main body 431 provides precise linear motion control for the main body 431. When the transmission shaft 321 rotates, the threaded segment 3211 interacts with the threaded hole of the main body 431, so that the main body 431 can move axially according to the predetermined thread pitch, so as to accurately control the state of the unloading member 20. At the same time, the threaded connection can resist the axial force through the friction between the threads, so as to prevent the main body 431 from sliding or deviating during movement, and thus the movement stability of the main body 431 is improved.

[0042] As Figures 1 to 3 In an embodiment, the bulk machine includes two adjusting members 50, which are installed at the ends of the first travel switch 41 and the second travel switch 42 away from the trigger member 43, so as to adjust the relative distance between the first travel switch 41 and the second travel switch 42 and the contact member.

[0043] In the embodiment, the bulk machine further includes two adjusting members 50, which are respectively installed at the ends of the first travel switch 41 and the second travel switch 42 away from the trigger member 43, so that the adjusting member 50 can independently adjust the position of each travel switch. The adjusting member 50 includes a mounting frame and an adjusting screw, and the adjusting screw is threadedly connected to the mounting frame and fixedly connected to the first travel switch 41 and the second travel switch 42. By rotating the adjusting screw, the relative position between the first travel switch 41 and the second travel switch 42 and the mounting frame can be adjusted, and thus the triggering position of the first travel switch 41 and the second travel switch 42 and the trigger member 43 is changed, so as to prevent the trigger member 43 from moving to the limit distance and still not abutting the two travel switches due to errors, and thus the working stability of the bulk machine is improved.

[0044] As Figures 1 to 3In one embodiment, the bulk loader includes two second traction members 60, and the two winding wheels 322 are respectively provided with a first winding groove 3221 and a second winding groove 3222, one end of the two first traction members 33 is wound around the two second winding grooves 3222, and the other end is connected to the telescopic section 21, and one end of the two second traction members 60 is wound around the two second winding grooves 3222, and the other end is connected to the telescopic section 21.

[0045] In this embodiment, the first winding groove 3221 and the second winding groove 3222 are opened in sequence along the axial direction of the winding wheel 322, and the first traction member 33 is wound in the two first winding grooves 3221, and the second traction member 60 is wound in the two second winding grooves 3222, so that the other ends of the two second traction members 60 and the two first traction members 33 are respectively connected to the four corners of the telescopic section 21, preventing the telescopic section 21 from offsetting or shaking during the telescopic process, thereby further improving the telescopic stability of the telescopic section 21 during telescopic operation.

[0046] like Figures 1 to 3 In one embodiment, the bulk loader includes four transition wheels 70 , which are arranged in an array and spaced apart from the transmission member 32 , and any one of the two first traction members 33 and the two second traction members 60 is wound around a transition wheel 70 .

[0047] In this embodiment, the two first traction members 33 and the two second traction members 60 correspond one-to-one to the four transition wheels 70. When the traction members are wound away from the winding groove, the traction members are first wound on the transition wheels 70, and then continue to move to drive the telescopic section 21 to telescope, thereby improving the smoothness of the movement of the traction members, reducing the friction generated during the movement, and thereby increasing their own service life.

[0048] like Figures 1 to 3 In one embodiment, the bulk loader includes a clamping member 80, which includes two connecting rods 81 and a clamping shaft 82. One end of the two connecting rods 81 is connected to the transmission member 32, and the clamping shaft 82 is installed between the other ends of the two connecting rods 81. The clamping shaft 82 abuts against the top ends of the first traction member 33 and the second traction member 60.

[0049] In this embodiment, the pressing shaft 82 of the pressing member 80 abuts against the top ends of the first and second pulling members 33, 60, enabling the pressing member 80 to apply pressure to the top ends of the first and second pulling members 33, 60, thereby preventing the first and second pulling members 33, 60 from slipping or falling off during transmission. Furthermore, the pressing shaft 82 can rotate relative to the first and second pulling members 33, 60 via connecting rods 81 at both ends to adjust the degree of pressure applied to the first and second pulling members 33, 60, thereby preventing transmission difficulties caused by excessive pressure and improving the flexibility of the pressing member 80.
