Description

Technical Field

[0001] The utility model relates to the technical field of material discharging devices, and particularly relates to an automatic discharging device for caked materials. Background Art

[0002] In the field of supercritical extraction, since the extraction process is carried out under high-pressure conditions, it often occurs that the materials after extraction are caked in the barrel. Moreover, since the material baskets are all slender structures with relatively large diameters, it is very difficult to discharge the materials.

[0003] For this reason, the applicant has developed a screw drilling and discharging device and method, and applied for a Chinese invention patent on June 26, 2023 (the publication number is CN116531792A). By connecting an extension rod between the driving rod and the screw drilling part, the height of the whole device is greatly reduced, and the application place of the device is expanded. And with the cooperation of the pulley group, during the whole discharging process, the construction personnel only need to control the control buttons of the electric rope coiling device and the motor and connect the extension rod, and the rest of the links are all automatically completed by the discharging device, greatly shortening the discharging time, reducing the manual labor intensity, with a simple structure and convenient operation.

[0004] However, during the discharging drilling process of the above device, it is necessary to install an extension rod on the driving rod, and during the process of lifting the screw drilling part after discharging, it is necessary to remove the extension rod. Moreover, whether installing the extension rod or removing the extension rod, it is necessary to support the screw drilling part below, and the whole discharging process is relatively cumbersome. And it is necessary to wait until the spiral blade drills to the bottom and drills out from the bottom of the barrel before the materials can fall. Therefore, during the screw drilling, the deeper it drills, the thicker the materials accumulate above the spiral blade, generating a greater pressure on the spiral blade, resulting in a greater resistance to be overcome during drilling, and a motor with a very high power is required to drive, increasing the energy consumption required for discharging. And the drilling resistance is too large, which easily causes the discharging drive mechanism to overload and trip. When in use, it is necessary to drill forward for a few minutes, then rotate in the reverse direction and lift and retreat a certain distance to make the scattered materials fall, and then continue to drill, thus affecting the whole discharging efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an automatic discharging device for caked materials. By moving the drill rod drive mechanism up and down along the guide rail on the column, the steps of installing or removing the extension rod are omitted; meanwhile, during the process of the spiral blade drilling, the scattered materials are discharged from the barrel through the discharge ports and the discharge channels on the spiral blade in turn, with low energy consumption, a simple structure, and improved operation efficiency.

[0006] To achieve the above object, the present utility model adopts the following technical solution: An automatic unloading device for compacted materials, comprising a column, a drill rod driving mechanism, a drill rod, and a spiral blade connected to the drill rod. A guide rail is provided on the column, and the drill rod driving mechanism moves up and down on the column along the guide rail;

[0007] The drill rod driving mechanism drives the spiral blade to rotate through the drill rod, and a plurality of discharge ports are provided on the spiral blade;

[0008] A discharge channel is provided at a position close to the center of the compacted material.

[0009] As an improvement of the present utility model, the drill rod driving mechanism includes a motor and a speed reducer connected to the motor, and the drill rod rotates under the drive of the speed reducer.

[0010] As an improvement of the present utility model, a box-type slider is sleeved on the column. A guide block adapted to the guide rail is provided on one inner side of the box-type slider, and the drill rod driving mechanism is installed on the box-type slider.

[0011] As an improvement of the present utility model, it further includes a main sprocket assembly, a slave sprocket assembly, and a sprocket driving member for driving the main sprocket assembly;

[0012] Both the main sprocket assembly and the sprocket driving member are installed at the top of the column, and the slave sprocket assembly drives the box-type slider to move up and down along the guide rail.

[0013] As an improvement of the present utility model, the column is installed on the mounting base through a slewing drive bearing.

[0014] The beneficial effects of the present utility model are as follows: An automatic unloading device for compacted materials. By moving the drill rod driving mechanism up and down on the column along the guide rail, the steps of installing or removing the extension rod in the prior art are omitted, the loading and unloading are convenient, and the occupied space is small. At the same time, during the drilling process of the spiral blade, the dispersed materials are discharged from the discharge port on the spiral blade and the discharge channel in sequence and then discharged from the barrel. Through the discharge port, during the entire unloading process, the dispersed materials can fall from the discharge port to the discharge channel, without causing the accumulation of materials above the spiral blade, thereby greatly reducing the resistance of the spiral blade during drilling, avoiding the tripping of the drill rod driving mechanism, further improving the working efficiency of unloading, and having low energy consumption, simple structure, and reliable operation. Before unloading, a discharge channel needs to be opened at a position close to the center of the compacted material in the barrel, and then the entire unloading process is automatically completed by the unloading device through manual control of the button switch, greatly shortening the unloading time, reducing the labor intensity of workers, and improving the operation efficiency.

[0015] Furthermore, a box - type slider is sleeved on the column. A guiding block adapted to the guide rail is arranged on one inner side of the box - type slider, and the drill pipe driving mechanism is installed on the box - type slider. Through the above design, it is convenient to realize the up - and - down movement of the drill pipe driving mechanism along the guide rail, and then drive the spiral blade to complete the drilling work. The structure is simple and the manufacturing cost is low.

[0016] Furthermore, the column is installed on the mounting seat through a rotary driving bearing. Through the rotary driving bearing, it is convenient to realize the rotation of the spiral blade at different angles, and the discharging operation of multiple cartridges distributed around the center of the column can be realized, and the operation is convenient and flexible.

The drill rod driving mechanism 6 drives the spiral blade 8 to rotate through the drill rod 7, and a plurality of discharge ports 81 are provided on the spiral blade 8. A discharge channel 11 is provided near the central position of the compacted material.

[0026] The above-mentioned drill rod driving mechanism 6 includes a motor 61, a speed reducer 62 connected to the motor 61, and a connecting seat 63. The top of the drill rod 7 is connected to the power output end of the speed reducer 62, and the drill rod 7 rotates under the drive of the speed reducer 62. The bottom of the drill rod 7 is connected to the spiral blade 8 through a pin shaft. The above-mentioned motor 61 and speed reducer 62 are installed on the connecting seat 63. It should be noted that the specific connection method between the drill rod 7 and the speed reducer 62 in this embodiment is not limited. For example, the top of the drill rod can be installed in the vertical through hole penetrating the speed reducer, or the drill rod can be connected to the downward extending power output shaft of the speed reducer, etc.

[0027] A box-type slider 4 is sleeved on the column 3. A guide block adapted to the guide rail 31 is provided on one inner side of the box-type slider 4. The drill rod driving mechanism 6 is installed on the box-type slider 4 through the connecting seat 63. Preferably, the above-mentioned guide block is a rolling pulley, making the box-type slider 4 move along the guide rail 31 more smoothly and quickly.

[0028] A main sprocket assembly 52 and a sprocket driving member 53 are installed on the top of the column 3. A secondary sprocket assembly 51 is provided on the column below the sprocket driving member 53. The above-mentioned main sprocket assembly 52 and secondary sprocket assembly 51 both include a driving wheel, a driven wheel, and a chain connected between the driving wheel and the driven wheel. Among them, the driven wheel of the main sprocket assembly 52 and the driving wheel of the secondary sprocket assembly 51 are coaxially distributed, and the driven wheel of the secondary sprocket assembly 51 is installed at the bottom of the column 3.

The above-mentioned sprocket driving member 53 can be a motor, a pneumatic motor, a hydraulic motor, etc., and this embodiment does not limit it. The column 3 is installed on the mounting seat 1 through a slewing drive bearing 2. In addition to bearings that can be controlled electrically, hydraulically, and pneumatically, the slewing drive bearing 2 can also be a non-powered slewing bearing.

Through rotation, it drills, cuts, and disperses the compacted material, so that the dispersed material is discharged from the discharge barrel 10 through its own weight through the discharge channel 11.

[0030] The working principle of the present utility model is as follows:

[0031] Stage of opening the discharging channel: The initial state of the drill pipe driving mechanism 6 is at the uppermost position of the column 3. Operate the rotary driving bearing 2 to rotate the column 3, thereby driving the drill pipe 7 on the drill pipe driving mechanism 6 to rotate above the hopper 10 and align with the center of the hopper; Install the through-hole drill bit on the drill pipe 7, operate the sprocket driving member 53 to move the drill pipe driving mechanism 6 downward, and rotate the through-hole drill bit to drill into the central position of the material. Stop after the through-hole drill bit drills through the center of the compacted material. At this time, a discharging channel 11 is formed in the center of the compacted material. It should be noted that the above-mentioned opening of the discharging channel can also be carried out by other methods, such as setting a channel pipe at the central position of the hopper 10. After the extraction reaction is completed, directly pulling out the channel pipe can automatically form the discharging channel 11.

[0032] Discharging stage: Operate the sprocket driving member 53 to move the drill pipe driving mechanism 6 upward, lift the through-hole drill bit out of the hopper 10, and replace the through-hole drill bit on the drill pipe 7 with the spiral blade 8; Operate the sprocket driving member 53 to move the drill pipe driving mechanism 6 downward and rotate the spiral blade 8 to drill into the central position of the material. The scattered material falls below the hopper 10 through the discharge port 81 and the discharging channel 11 in sequence. After the discharging is completed, operate the sprocket driving member 53 to move the drill pipe driving mechanism 6 upward and lift the spiral blade out of the hopper 10, and the discharging ends.
