Description

Technical Field

[0001] This utility model relates to a sampling machine, specifically a dual-drive scraper sampling machine. Background Technology

[0002] When transporting coal by belt conveyor at the port, it is necessary to sample the coal. The current sampling machine is only driven by a single motor. Once the motor is damaged, it cannot complete the sampling task. At the same time, some material will fly out from both sides of the reducing chute during sampling by the cutter of the existing sampling machine. It needs to be cleaned regularly, which occupies manpower and requires the machine to be stopped during cleaning, which affects the smooth progress of the sampling work.

[0003] Currently, a utility model patent with publication number CN212621776U discloses a belt linear divider, including a housing, a motor reducer installed inside the housing, and a transmission device installed on the motor reducer. The transmission device includes a driven sprocket, a driving sprocket, and a double-row chain meshing between the driven sprocket and the driving sprocket. A sampling scraper is fixedly installed at a preset position on the double-row chain, and a pair of limiting rods are fixedly installed on the sampling scraper. A guide device matching the limiting rods is fixedly installed on the housing. A material outlet is provided at one end of the housing, with the opening facing downwards. A pair of tension plates are installed inside the housing, and the driven sprocket is rotatably connected to the tension plates. The divider in this utility model is used in conjunction with a flat belt, occupies little space, leaves less residue when scraping material on the belt, and has excellent effect when the material flow is small, making it particularly suitable for dividing fine materials.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN212621776U is mainly used for the reduction of flat belts in factories, and is not applicable to the sidewall belts used in ports. At the same time, the sidewall belts used in port transportation run at a relatively fast speed, usually 4 meters per second. The scraping method of this patent is too slow and is not suitable for the transportation rhythm of ports. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a dual-drive scraper sampler, which can effectively prevent equipment downtime for maintenance due to motor damage and effectively reduce material scattering.

[0006] To achieve the above objectives, this utility model provides a dual-drive scraper sampling machine, comprising a sampling component, a sampling component housing, a cutter, a return component, a return chute, a reduction chute, a main belt support plate, a return port, a second sampling component drive motor, a first sampling component drive motor, an equipment mounting platform, a belt baffle, and a conveyor belt. The sampling component is fixedly installed on the equipment mounting platform. The return component is connected to one side of the sampling component. The first sampling component drive motor drives the sampling component. The return component further includes a return chute and a reduction chute. Reduction chutes are fixedly installed on both sides of the return chute. A return port is opened on the surface of the return chute corresponding to the lower end of the reduction chute. The main belt support plate is fixedly installed on the upper part of the return chute and the reduction chute facing the sampling component. The belt baffle is installed on the lower part of the equipment mounting platform via a bracket.

[0007] In addition, the dual-drive scraper sampler proposed according to the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, a second sampling component drive motor and a first sampling component drive motor are respectively installed on the equipment mounting platforms before and after the sampling component. The second sampling component drive motor and the first sampling component drive motor are respectively connected to the front and rear of the sampling component through a clutch transmission.

[0009] As a further improvement of this utility model, a cutter is installed inside the sampling component housing of the sampling component, and the two ends of the cutter's rotating shaft are respectively connected to the second sampling component drive motor and the first sampling component drive motor through a clutch transmission.

[0010] As a further improvement of this utility model, the second sampling component drive motor and the first sampling component drive motor are connected to the controller via wires.

[0011] As a further improvement of this utility model, the equipment installation platform is equipped with a ladder.

[0012] By employing the above-described solution, this utility model has at least the following advantages: Compared with conventional sampling machines, by adding a second driving motor for the sampling component, the equipment simultaneously possesses two driving motors, allowing the other motor to immediately start working after one motor fails, effectively preventing equipment downtime for maintenance due to motor failure. Simultaneously, by adding return chutes on both sides of the reducing chute, the feed inlet area is increased, effectively reducing material scattering. Attached Figure Description

[0018] The dual-drive scraper sampler of this utility model is described below with reference to the accompanying drawings.

[0019] In Embodiment 1 of this application, as Figures 1 to 3 As shown, this dual-drive scraper sampler (hereinafter referred to as "the present invention") includes a sampling component 1, a return component 2, a second sampling component drive motor 3, a first sampling component drive motor 4, an equipment mounting platform 5, a belt baffle 6, and a conveyor belt 7. The sampling component 1 is fixedly installed on the equipment mounting platform 5. The return component 2 is connected to one side of the sampling component 1. The first sampling component drive motor 4 drives the sampling component 1. The return component 2 also includes a return chute 21 and a reduction chute 22. The reduction chute 22 is fixedly installed on both sides of the return chute 21. A return port 24 is opened on the surface of the return chute 21 corresponding to the lower end of the reduction chute 22. A main belt support plate 23 is fixedly installed on the upper part of the return chute 21 and the reduction chute 22 facing the sampling component 1. The belt baffle 6 is installed on the lower part of the equipment mounting platform 5 through a bracket. The second sampling component drive motor 3 and the first sampling component drive motor 4 are respectively installed on the equipment mounting platform 5 before and after the sampling component 1. The second sampling component drive motor 3 and the first sampling component drive motor 4 are respectively connected to the front and rear of the sampling component 1 through a clutch. The sampling component 1 has a cutter 12 installed inside the sampling component housing 11. The two ends of the rotating shaft of the cutter 12 are respectively connected to the sampling component drive motor 3 and the sampling component drive motor 4 via clutch transmission.

[0020] The belt linear divider with utility model publication number CN212621776U (hereinafter referred to as "the patent") is mainly used for the divider work of flat belts in factories. It is not suitable for the sidewall belts used in ports. At the same time, the sidewall belts used in port transportation run at a relatively high speed, usually 4 meters per second. The scraping method of the patent is too slow and is not suitable for the transportation rhythm of ports. However, the present invention uses a fast rotating cutter 12 to directly cut the coal on the belt and send the coal sample into the return material assembly 2, which is particularly suitable for the sidewall belts used in ports.

[0021] This second embodiment is structurally similar to the first embodiment, except that the sampling component drive motor 3 and the sampling component drive motor 4 are connected to the controller via wires. This allows the sampling rate to be adjusted according to operating procedures.

[0022] To further optimize the work efficiency of this application and facilitate maintenance by staff, the equipment installation platform 5 is equipped with a ladder.

[0023] Once the dual-drive scraper sampler is installed, the equipment is ready for use.

[0024] When this utility model is used, its specific operation is as follows:

[0025] In use, the conveyor belt 7, loaded with coal, runs rapidly, with its edge entering the pre-reserved groove in the main belt support plate 23. The sampling interval is pre-set in the PLC according to different belt speeds, flow rates, and bandwidths. The sampling component drive motor 4 drives the cutter 12 in the sampling component housing 11 to rotate. The rotating cutter 12 kicks the coal sample into the return material component 2. With the combined shielding of the sampling component housing 11, the return material chute 21, and the reducing chute 22, the material falls into the return material chute 21 and the reducing chute 22. The material in the reducing chute 22 enters the coal sample conveyor belt or the coal sample collection trough through the lower opening. The material in the return material chute 21, under the action of gravity, re-enters the reducing chute 22 along the return port 24 and enters the coal sample conveyor belt or the coal sample collection trough through the lower opening.

[0026] When the sampling component drive motor 4 is damaged, the control unit controls the clutch of the sampling component drive motor 4 to disconnect the transmission connection, and controls the clutch of the sampling component drive motor 3 to connect the transmission connection to the cutter 12. The sampling component drive motor 3 takes over driving the cutter 12, and the staff can repair the damaged sampling component drive motor 4 at an opportune time.

[0027] In summary, the dual-drive scraper sampler of this utility model embodiment, by adding a second driving motor 3 for the sampling component, enables the equipment to have two driving motors simultaneously. This allows the equipment to immediately start working on the other motor after one motor fails, effectively preventing equipment downtime for maintenance due to motor failure. Simultaneously, by adding return chutes 21 on both sides of the reducing chute 22, the feed inlet area is increased, effectively reducing material scattering.
