[0008] 1) The storage capacity of a single storage device is insufficient;

[0009] 2) The structure of the storage device is too simple and cannot meet the requirements of continuous operation;

[0010] 3) The spring clips and gauge baffles are very easy to disperse, resulting in uneven material storage. Summary of the Invention

[0011] In view of this, the purpose of this application is to provide a method for storing and handling bulk materials for track fasteners, so as to solve the technical problems of low operating efficiency, small storage capacity and inability to meet the requirements of continuous operation of existing material storage methods.

[0012] To achieve the aforementioned objectives, this application specifically provides a technical solution for a method of storing and handling bulk materials for track fasteners. The storage device includes: an outer cylinder support assembly and an inner cylinder assembly arranged concentrically from the outside to the inside; an inner cylinder rotation mechanism rotatably disposed between the outer cylinder support assembly and the inner cylinder assembly; a flipping mechanism disposed on the side of the outer cylinder support assembly; and a discharge port opening and closing mechanism disposed at the bottom of the inner cylinder assembly. The inner cylinder assembly is provided with a plurality of guide columns arranged in a circular array. The discharge port opening and closing mechanism includes an opening and closing cylinder and an opening and closing baffle. The method includes the following steps:

[0013] S1) The storage device is flipped to a set angle by the flipping mechanism, so that the discharge port is in an inclined upward position;

[0014] S2) Open the opening and closing baffle at the outlet position by controlling the opening and closing cylinder, load the track fastener on the guide column at the outlet position, and then control the opening and closing cylinder to close the opening and closing baffle at the outlet position.

[0015] S3) Control the inner cylinder rotation mechanism to rotate the inner cylinder assembly by a set angle, so that the track fasteners on the adjacent guide columns rotate to the discharge port position;

[0016] S4) Repeat steps S2) to S3) until all guide columns of the inner cylinder are fully loaded with track fasteners;

[0017] S5) After the storage device is fully loaded, control the tilting mechanism to tilt the entire storage device to the working position, at which time the discharge port is vertically downward.

[0018] S6) Rotary control aligns the feed inlet of the dispensing device with the discharge outlet of the storage device and locks the dispensing device and the storage device together;

[0019] S7) Control the opening and closing cylinder to open the opening and closing baffle at the discharge port position, and the track fastener on the guide column at this position falls onto the material distribution device;

[0020] S8) Start the material distribution device to begin distributing materials. The track fasteners on the guide column fall down until they are completely cleared.

[0021] S9) Control the opening / closing cylinder to close the opening / closing baffle;

[0022] S10) Start the inner cylinder rotation mechanism to rotate the guide column near the discharge port by a set angle to the discharge port position;

[0023] S11) Repeat steps S7) to S10) until all the track fasteners in all guide columns are cleared and the bulk material operation is completed.

[0024] Furthermore, the inner cylinder assembly is connected and installed onto the body of the bulk material handling vehicle via the outer cylinder support assembly. The outer cylinder support assembly is a circular frame structure composed of a top cover assembly, an outer frame assembly, and a base assembly. The top cover assembly and the base assembly are connected to the outer frame assembly so that the inner cylinder assembly can be installed inside the outer cylinder support assembly. The top cover assembly is movably connected to the inner cylinder assembly, and a discharge port opening and closing mechanism is provided on the base assembly.

[0025] Furthermore, the inner cylinder assembly also includes a connecting plate, a motor connecting seat, a connecting rod, a fixing plate, and a guide seat. One end of the guide post is inserted into the corresponding hole on the connecting plate and fixedly connected thereto. The other end of the guide post has a cantilever beam structure to facilitate the loading and unloading of the track fasteners. The connecting plate has a circular structure, and the motor connecting seat has a cylindrical structure and is connected to the center of the connecting plate, so that the inner cylinder rotation mechanism, after being installed in the motor connecting seat, drives the connecting plate to rotate together. One end of the connecting rod is connected to the connecting plate, and the other end is connected to the guide seat. The middle of the connecting rod is fixed by a fixing plate to increase overall rigidity. The connecting rod transfers the weight of the track fasteners loaded on the guide seat to the outer cylinder support assembly through the connecting plate.

[0026] Furthermore, by adjusting the shape of the guide posts to accommodate the loading of the rail fasteners, the rail fasteners can be neatly arranged on a single guide post. Several guide posts arranged in a circular array are provided in the inner cylinder assembly to meet the rail fastener loading requirements of the bulk material handling vehicle.

[0027] Furthermore, the inner cylinder rotation mechanism includes a rotary support, a motor mounting base, and a first geared motor mounted on the motor mounting base. The inner cylinder rotation mechanism provides power for the rotation of the inner cylinder assembly, thereby sequentially rotating the track fasteners mounted on the guide columns to the discharge port position. The top cover assembly is movably connected to the inner cylinder assembly via the rotary support, and when the outer cylinder support assembly is fixed, the inner cylinder assembly rotates under the action of the first geared motor.

[0028] Furthermore, the tilting mechanism includes a second geared motor and a bearing housing, with the second geared motor mounted on the rotating shaft via the bearing housing. The second geared motor provides power for the outer cylinder support assembly and the inner cylinder assembly to tilt together, thereby enabling the storage device to switch between a working state and a feeding state.

[0029] Furthermore, the discharge port opening and closing mechanism includes an opening and closing cylinder and an opening and closing baffle, used to control whether the track fastener on the guide column falls onto the material distribution device of the bulk material handling vehicle. The opening and closing cylinder and the opening and closing baffle are detachably connected, and the opening and closing baffle is arranged along the circumference of the inner cylinder and located at the lower part of the guide column. When the material distribution device is aligned below the discharge port, the piston rod of the opening and closing cylinder retracts to its shortest position, causing the opening and closing baffle at the discharge port position to slide towards the opening and closing cylinder, and the track fastener on the guide column at this position falls onto the material distribution device of the bulk material handling vehicle.

[0030] Furthermore, after all the track fasteners on the guide column have fallen down, the piston rod of the opening and closing cylinder extends, causing the opening and closing baffle at that position to slide to the maximum position away from the opening and closing cylinder. At this time, the inner cylinder rotating mechanism rotates by a set angle, causing the adjacent guide column to rotate to the discharge port position and begin to drop material. The above actions are repeated until all the track fasteners on all the guide columns have fallen down.

[0031] Furthermore, a connector is provided at the piston rod end of the opening / closing cylinder, and a sliding groove is provided at the bottom of the connector, which is detachably connected to a protrusion on the opening / closing baffle. The protrusion of the opening / closing baffle is driven to rotate and move in and out of the sliding groove of the connector by an inner cylinder rotating mechanism, so as to realize the connection and separation of the opening / closing cylinder and the opening / closing baffle.

[0032] Furthermore, several guide columns are arranged in a circular array along the circumference of the inner cylinder.

[0033] By implementing the technical solution of the rail fastener material storage and bulk material operation method provided in this application, the following beneficial effects are achieved:

[0034] (1) The rail fastener storage and bulk material operation method of this application has a simple structure of storage device, greatly increases storage capacity, and can achieve a storage capacity of thousands of pieces. At the same time, the storage device has a transmission device inside, which can meet the requirements of continuous material replenishment operation and improve the operation efficiency by several times.

[0035] (2) The rail fastener storage and dispersal operation method of this application uses guide columns with shapes similar to elastic bars or gauge baffles to arrange materials in the inner cylinder, so that the elastic bars and gauge baffles can enter the dispersing device smoothly and orderly from the storage device. The elastic bars and gauge baffles are arranged neatly and orderly inside the storage device and are not easy to disperse. At the same time, the storage elastic bars and gauge baffles can be changed according to the shape of the guide columns, which has good compatibility.

[0036] (3) The rail fastener storage and bulk material operation method of this application adopts a ring matrix arrangement and inner cylinder rotation device for the guide column of the storage, which can ensure the orderly connection of materials, save the storage space and conveying space of the storage device, and adopt the slewing support bearing method as a whole, which can meet the requirements of rotation operation and the stress requirements when the load is fully loaded.

[0037] (4) The rail fastener storage and bulk material operation method of this application has 20 columns of materials inside the storage device and only one discharge port. The 20 columns of materials are rotated one by one to the discharge port position for discharge by the internal rotating device. The discharge port of the storage device is also the feeding port, which can solve the technical problems such as the difficulty of orderly storage caused by the irregularity of materials in the elastic bar or gauge baffle.

Detailed Implementation

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] As attached Figure 1 To be continued Figure 22 As shown, a specific embodiment of the method for storing and handling bulk materials for track fasteners according to this application is given. The application will be further described below with reference to the accompanying drawings and specific embodiments.

[0064] This application proposes a method for storing and handling bulk materials using elastic clips and gauge baffles for railway bulk material handling vehicles. The storage device 10 consists of an outer cylinder support 1, an inner cylinder 2, an inner cylinder rotating device 3, a tilting mechanism 4, and a discharge port opening and closing mechanism 5, enabling the smooth and efficient conveying of elastic clips and gauge baffles to the distribution device 20. This application, considering the special characteristics of elastic clips and gauge baffles, designs a storage device 10 with a simple structure, large storage capacity, high operating efficiency, and the ability to meet continuous material replenishment requirements.

[0065] Example 1

[0066] As attached Figure 1 and attached Figure 2 As shown, an embodiment of a track fastener storage device based on the method of this application specifically includes:

[0067] The outer cylinder support 1 and the inner cylinder 2 are arranged concentrically from the outside to the inside. The inner cylinder 2 adopts a circular rotating array structure to orderly store the track fasteners 14 to be dispersed (the track fasteners 14 are dispersed on the sleepers 9).

[0068] An inner cylinder rotation mechanism 3 is rotatably disposed between the outer cylinder support assembly 1 and the inner cylinder assembly 2. The inner cylinder rotation mechanism 3 can drive the inner cylinder assembly 2 to rotate relative to the outer cylinder support assembly 1, and is used to rotate the track fastener 14 to the discharge port position.

[0069] The flipping mechanism 4, located on the side of the outer cylinder support assembly 1, provides power for the flipping of the outer cylinder support assembly 1 and the inner cylinder assembly 2.

[0070] The discharge port opening and closing mechanism 5 is located at the bottom of the inner cylinder assembly 2, which controls the track fastener 14 to fall onto the material distribution device 20. The discharge port 16 is also the feeding port.

[0071] The track fastener 14 mainly includes elastic clips and gauge baffles. The inner cylinder assembly 2 is formed by an array of elliptical guide posts (the elastic clip storage device is formed by an array of 40 guide posts, and the gauge baffle storage device is formed by an array of 20 elliptical guide posts). In the prior art, a single storage device can store approximately 100 pieces, while the storage device 10 described in this embodiment can store up to 1760 pieces.

[0072] When performing bulk material handling, the tilting mechanism 4 controls the outer cylinder support assembly 1 and the inner cylinder assembly 2 to tilt so that the discharge port 16 is vertically downward. When feeding material is required, the tilting mechanism 4 controls the outer cylinder support assembly 1 and the inner cylinder assembly 2 to tilt so that the discharge port 16 is converted into a feeding port and is kept at an upward angle for feeding.

[0073] The inner cylinder assembly 2 is connected and installed onto the body of the bulk material handling vehicle 8 via the outer cylinder support assembly 1. (See attached diagram) Figure 3 , 4 As shown in Figure 5, the outer cylinder support assembly 1 is a circular frame structure composed of a top cover assembly 11, an outer frame assembly 12, and a base assembly 13. Both the top cover assembly 11 and the base assembly 13 are bolted to the outer frame assembly 12, allowing the inner cylinder assembly 2 to be installed inside the outer cylinder support assembly 1. Rotating shafts 15 are provided on both sides of the outer frame assembly 12. The top cover assembly 11 is movably connected to the inner cylinder assembly 2, and the discharge port opening and closing mechanism 5 is located on the base assembly 13.

[0074] The main function of the inner cylinder component 2 described above is to arrange and store the elastic clips or gauge baffles in an orderly manner as required. (See attached image) Figure 6 and attached Figure 7As shown, the inner cylinder assembly 2 further includes a connecting plate 21, a motor connecting seat 22, a guide column 23, a connecting rod 24, a fixing plate 25, and a guide seat 26. One end of the guide column 23 is inserted into the corresponding hole on the connecting plate 21 and fixedly connected thereto. The other end of the guide column 23 is a cantilever beam structure to facilitate the loading and unloading of the track fastener 14. The connecting plate 21 has a circular structure, and the motor connecting seat 22 has a cylindrical structure and is connected to the center of the connecting plate 21 so that the inner cylinder rotating mechanism 3 can rotate together with the connecting plate 21 after being installed in the motor connecting seat 22. One end of the connecting rod 24 is connected to the connecting plate 21, and the other end is connected to the guide seat 26. The middle part of the connecting rod 24 is fixed by the fixing plate 25 to increase the overall rigidity. The weight of the track fastener 14 loaded on the guide seat 26 is transferred to the outer cylinder support assembly 1 through the connecting plate 21 via the connecting rod 24.

[0075] The elastic clips and gauge baffles are prone to dispersion, leading to uneven storage. The track fastener storage device described in Embodiment 1 adjusts the shape of the guide post 23 to adapt to the loading of the track fasteners 14, so that the track fasteners 14 can be neatly arranged on a single guide post 23. The inner cylinder assembly 2 is provided with several guide posts 23 arranged in a circular array to meet the track fastener loading capacity required by the bulk material handling vehicle 8. Several guide posts 23 are arranged in a circular array along the circumference of the inner cylinder assembly 2. The entire inner cylinder assembly 2 is provided with 20 guide posts 23 arranged in an array to meet the fastener (i.e., elastic clip) loading capacity required by the bulk material handling vehicle 8. The function of the 10 connecting rods 24 is to bear the weight of the material, transfer the weight to the connecting plate 21, and then to the outer frame assembly 12. The function of the fixing plate 25 is to increase the rigidity of the inner cylinder assembly 2 when it rotates.

[0076] As attached Figure 8 As shown, the inner cylinder rotation mechanism 3 further includes a rotary support 31, a motor mounting base 32, and a first geared motor 33 mounted on the motor mounting base 32. The inner cylinder rotation mechanism 3 provides power for the rotation of the inner cylinder assembly 2, so as to rotate the track fasteners 14 mounted on the guide column 23 sequentially to the discharge port position. The top cover assembly 11 is movably connected to the inner cylinder assembly 2 through the rotary support 31, and the inner cylinder assembly 2 can rotate under the action of the first geared motor 33 when the outer cylinder support assembly 1 is fixed.

[0077] The tilting mechanism 4 further includes a second geared motor 41 and two bearing seats 7. The second geared motor 41 is mounted on the rotating shaft 15 via the bearing seats 7. The second geared motor 41 provides power for the outer cylinder support assembly 1 and the inner cylinder assembly 2 to tilt together, thereby enabling the storage device 10 to operate in the working state (as shown in the attached diagram). Figure 9 The image shows the work station (A) and the material loading status (as shown in the attached image). Figure 10 Switching between the loading positions (as shown in B) is possible.

[0078] As attached Figure 11 , 12 As shown in Figure 13, the discharge port opening and closing mechanism 5 further includes an opening and closing cylinder 51 and an opening and closing baffle 52, used to control whether the track fastener 14 on the guide column 23 falls onto the material distribution device 20 of the bulk material handling vehicle 8. The opening and closing cylinder 51 and the opening and closing baffle 52 are detachably connected. The opening and closing baffle 52 is arranged along the circumference of the inner cylinder assembly 2 and is located at the lower part of the guide column 23, adopting a circular matrix structure like the guide column 23. When the material distribution device 20 is aligned below the discharge port 16, the piston rod of the opening and closing cylinder 51 retracts to its shortest position, causing the opening and closing baffle 52 at the discharge port position to slide toward the opening and closing cylinder 51, and the track fastener 14 on the guide column 23 at this position falls onto the material distribution device of the bulk material handling vehicle. After all the track fasteners 14 on the guide column 23 have fallen down, the piston rod of the opening and closing cylinder 51 extends, causing the opening and closing baffle 52 at that position to slide to the maximum position away from the opening and closing cylinder 51. Then, the inner cylinder rotating mechanism 3 rotates by a set angle, causing the adjacent guide column 23 to rotate to the discharge port position and start dropping material. The above actions are repeated until all the track fasteners 14 on all the guide columns 23 have fallen down.

[0079] As attached Figure 12 As shown, a connector 53 is further provided at the piston rod end of the opening / closing cylinder 51, and a sliding groove 54 is provided at the bottom of the connector 53. The sliding groove 54 is detachably connected to the protrusion 55 on the opening / closing baffle 52. The protrusion 55 of the opening / closing baffle 52 is driven to rotate and move in and out of the sliding groove 54 of the connector 53 by the inner cylinder rotating mechanism 3, thereby realizing the connection and separation of the opening / closing cylinder 51 and the opening / closing baffle 52.

[0080] Example 2

[0081] As attached Figure 14 To be continued Figure 22 As shown, an embodiment of the bulk material handling vehicle 8 based on the method of this application specifically includes: a track fastener storage device 10 as described in embodiment 1, and a rotating shaft 15 of the outer frame 12 is mounted on the mounting frame 6 of the bulk material handling vehicle 8 via a bearing seat 7.

[0082] Example 3

[0083] As attached Figure 14 To be continued Figure 22As shown, an embodiment of the method for storing and distributing track fasteners according to this application is disclosed. The storage device 10 includes: an outer cylinder support assembly 1 and an inner cylinder assembly 2 arranged concentrically from the outside to the inside; an inner cylinder rotation mechanism 3 rotatably disposed between the outer cylinder support assembly 1 and the inner cylinder assembly 2; a flipping mechanism 4 disposed on the side of the outer cylinder support assembly 1; and a discharge port opening and closing mechanism 5 disposed at the bottom of the inner cylinder assembly 2. The inner cylinder assembly 2 is provided with a plurality of guide columns 23 arranged in a circular array. The discharge port opening and closing mechanism 5 includes an opening and closing cylinder 51 and an opening and closing baffle 52. The method specifically includes the following steps:

[0084] S1) Loading operation is carried out on the storage device 10 at the base. The storage device 10 is flipped to a set angle (such as about 110°) by operating the flipping mechanism 4, so that the discharge port 16 at the bottom is in an inclined upward position.

[0085] S2) By controlling the opening and closing cylinder 51 to open the opening and closing baffle 52 at the discharge port 16, the track fasteners 14 are loaded in an orderly manner on the guide post 23 at the discharge port 16 until the guide post 23 is full (e.g., 88), and then the opening and closing cylinder 51 is controlled to close the opening and closing baffle 52 at the discharge port 16.

[0086] S3) Control the inner cylinder rotation mechanism 3 to rotate the inner cylinder assembly 2 by a set angle (e.g., 18°), so that the track fastener 14 on the adjacent guide column 23 rotates to the position of the discharge port 16.

[0087] S4) Repeat steps S2) to S3) until all guide posts 23 (e.g., 20 posts) of the inner cylinder assembly 2 are loaded with track fasteners 14;

[0088] S5) After the storage device 10 is fully loaded, control the flipping mechanism 4 to rotate about 110° in the opposite direction to step S1) to flip the entire storage device 10 to the working position, so that the discharge port 16 at the bottom is vertically downward and then stops. At this time, the loading operation is completed.

[0089] When the (fastener) bulk material handling vehicle 8 arrives at the construction site, the next device of the storage device 10 (the material distribution device 20) is in operation.

[0090] S6) Rotation control aligns the feed inlet of the dispensing device 20 with the discharge outlet 16 of the storage device 10 and locks the dispensing device 20 and the storage device 10.

[0091] S7) Control the opening and closing cylinder 51 to open the opening and closing baffle 52 at the discharge port 16, and the track fastener 14 on the guide column 23 at this position falls onto the material distribution device 20.

[0092] S8) Start the material distribution device 20 to start distributing materials, and the track fastener 14 on the guide column 23 falls down until it is completely cleared;

[0093] S9) After the sensor identifies that all the materials in the column have been dropped, it controls the opening and closing cylinder 51 to close the opening and closing baffle 52.

[0094] S10) Start the inner cylinder rotation mechanism 3 to rotate the guide column 23 near the discharge port 16 by a set angle (e.g., 18°) so that the material on the second column of guide columns 23 is conveyed to the discharge port 16.

[0095] S11) Repeat steps S7) to S10) until all the track fasteners 14 in all guide columns 23 (e.g., 20 columns) are cleared to complete the bulk material handling.

[0096] Among them, the cylinder can be further equipped with other types of propulsion devices, such as hydraulic cylinders, electric cylinders, etc., to ensure that material can be stored rhythmically and periodically.

[0097] The inner cylinder assembly 2 is connected and installed to the body of the bulk material handling vehicle 8 via the outer cylinder support assembly 1. The outer cylinder support assembly 1 is a circular frame structure composed of a top cover assembly 11, an outer frame assembly 12, and a base assembly 13. The top cover assembly 11 and the base assembly 13 are connected to the outer frame assembly 12 so that the inner cylinder assembly 2 can be installed inside the outer cylinder support assembly 22. The top cover assembly 11 is movably connected to the inner cylinder assembly 2, and a discharge port opening and closing mechanism 5 is provided on the base assembly 13.

[0098] The inner cylinder assembly 2 further includes a connecting plate 21, a motor connecting seat 22, a connecting rod 24, a fixing plate 25, and a guide seat 26. One end of the guide post 23 is inserted into the corresponding hole on the connecting plate 21 and fixedly connected thereto. The other end of the guide post 23 is a cantilever beam structure to facilitate the loading and unloading of the track fastener 14. The connecting plate 21 has a circular structure, and the motor connecting seat 22 has a cylindrical structure and is connected to the center of the connecting plate 21 so that the inner cylinder rotating mechanism 3 can rotate together with the connecting plate 21 after being installed in the motor connecting seat 22. One end of the connecting rod 24 is connected to the connecting plate 21, and the other end is connected to the guide seat 26. The middle part of the connecting rod 24 is fixed by the fixing plate 25 to increase the overall rigidity. The connecting rod 24 transfers the weight of the track fastener 14 loaded on the guide seat 26 to the outer cylinder support assembly 1 through the connecting plate 21.

[0099] By adjusting the shape of the guide post 23 to accommodate the loading of the track fastener 14, the track fastener 14 can be neatly arranged on a single guide post 23. Several guide posts 23 arranged in a circular array are provided in the inner cylinder assembly 2 to meet the track fastener loading capacity required by the bulk material handling vehicle 8. The guide posts 23 are arranged in a circular array along the circumference of the inner cylinder assembly 2.

[0100] The inner cylinder rotation mechanism 3 further includes a rotary support 31, a motor mounting base 32, and a first geared motor 33 mounted on the motor mounting base 32. The inner cylinder rotation mechanism 3 provides power for the rotation of the inner cylinder assembly 2, thereby rotating the track fasteners 14 mounted on the guide column 23 sequentially to the discharge port position. The top cover assembly 11 is movably connected to the inner cylinder assembly 2 via the rotary support 31, allowing the inner cylinder assembly 2 to rotate under the action of the first geared motor 33 when the outer cylinder support assembly 1 is fixed.

[0101] The tilting mechanism 4 further includes a second geared motor 41 and two bearing seats 7, with the second geared motor 41 mounted on the rotating shaft 15 via the bearing seats 7. The second geared motor 41 provides power for the outer cylinder support assembly 1 and the inner cylinder assembly 2 to tilt together, thereby enabling the storage device 10 to switch between the working state and the feeding state.

[0102] The discharge port opening and closing mechanism 5 further includes an opening and closing cylinder 51 and an opening and closing baffle 52, used to control whether the track fastener 14 on the guide column 23 falls onto the material distribution device 20 of the bulk material handling vehicle. The opening and closing cylinder 51 and the opening and closing baffle 52 are detachably connected, and the opening and closing baffle 52 is arranged along the circumference of the inner cylinder assembly 2 and located at the lower part of the guide column 23. When the material distribution device 20 is aligned below the discharge port 16, the piston rod of the opening and closing cylinder 51 retracts to its shortest position, causing the opening and closing baffle 52 at the discharge port position to slide toward the opening and closing cylinder 51, and the track fastener 14 on the guide column 23 at this position falls onto the material distribution device 20 of the bulk material handling vehicle 8.

[0103] After all the track fasteners 14 on the guide column 23 have fallen, the piston rod of the opening and closing cylinder 51 extends, causing the opening and closing baffle 52 at that position to slide to the maximum position away from the opening and closing cylinder 51. Then, the inner cylinder rotating mechanism 3 rotates by a set angle (e.g., 18°), causing the adjacent guide column 23 to rotate to the discharge port position and start dropping material. The above actions are repeated until all the track fasteners 14 on all columns (e.g., 20 columns) of guide column 23 have fallen.

[0104] A threaded connector 53 is provided at the piston rod end of the opening / closing cylinder 51, and a groove 54 is provided at the bottom of the connector 53. The groove 54 is detachably connected to the protrusion 55 on the opening / closing baffle 52. The protrusion 55 of the opening / closing baffle 52 is driven to rotate and move in and out of the groove 54 of the connector 53 by the inner cylinder rotating mechanism 3, so as to realize the connection and separation of the opening / closing cylinder 51 and the opening / closing baffle 52.
