Description

Technical Field

[0001] This patent application belongs to the field of sampling equipment technology, and more specifically, relates to an automatic sampling device for powdery materials. Background Technology

[0002] In modern enterprise production lines, chutes are frequently used to transfer materials from one process to the next, offering convenience and speed. However, sampling is necessary during the material handling process to assess the status of the previous process's processing results. Common sampling methods include: direct manual sampling and sampling using a manual sampler.

[0003] Manual sampling is inefficient, labor-intensive, generates significant dust spillage, creates a poor working environment, and poses safety hazards when the chute is high or the sampling position is high. Manual samplers also have similar problems.

[0004] The current sampling method cannot be used to take samples at regular intervals. Each sampling requires the sampling personnel to be on-site to operate and manually control the time interval. Slight negligence will result in large errors. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic sampling device for powdered materials. This device automatically samples in the material flow, which does not affect the material flow in the conveying chute, and can sample at fixed intervals, making the sample more representative. It directly replaces manual operation with automation, reduces the labor intensity of workers, eliminates safety hazards, and improves work efficiency.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] An automatic sampling device for powdered materials includes a control unit and a material receiving unit.

[0008] The control unit includes a control box, a control line connected to the control box, an electric push rod connected to the control line, and a housing fixed inside the electric push rod. The control box is used to control the electric push rod to extend and retract at time intervals, and the housing is connected to a chute.

[0009] The receiving section includes a receiving trolley connected to the stroke rod of the electric push rod, a trolley track that cooperates with the receiving trolley, a soft sweeper and a hard sweeper located on the box, a rear wheel and a front wheel of the trolley located at the bottom of the receiving trolley, a rear sweeper located at the bottom of the receiving trolley and behind the rear wheel, a front sweeper located at the bottom of the receiving trolley and in front of the front wheel, and a receiving box located at the bottom of the box, with the receiving box corresponding to the receiving trolley. The receiving trolley and the trolley track are both located inside the box.

[0010] The bottom plate of the box located above the receiving box has a hollow structure, meaning there is no bottom plate at the connection between the box and the receiving box. Both the soft and hard sweepers are located above the receiving box and correspond to it. This allows the receiving trolley to sweep the material down using the soft and hard sweepers after receiving it, so that the material falls into the receiving box through the hollow structure.

[0011] Furthermore, the rear wheels of the trolley are installed at the very rear of the receiving trolley, while the front wheels are installed in the middle of the receiving trolley.

[0012] Furthermore, both the rear and front wheels of the trolley are V-shaped track wheels, and the trolley track is also V-shaped. The two tracks are angled in the same direction and used together.

[0013] Furthermore, the height of both the soft and hard scrapers is adjustable.

[0014] Furthermore, the enclosure is made of metal.

[0015] Furthermore, the electric actuator is a pen-type electric actuator, with the actuator's stroke rod positioned in the middle of the housing when extended.

[0016] Furthermore, a sealing plate is connected to the front of the electric push rod, and a hole is provided in the middle of the sealing plate for the stroke rod to pass through. The sealing plate is installed inside the box, and the receiving trolley is located outside the sealing plate.

[0017] Furthermore, the soft scraper and the hard scraper are located at the rear and front ends of the receiving trolley in the direction of travel, respectively.

[0018] The beneficial effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0019] This device, through automatic settings in the control box, allows an electric push rod to drive a receiving trolley that periodically extends into the chute to sample the material flow. This process does not disrupt the material flow within the chute and allows sampling at fixed intervals. Soft and hard sweepers then sweep all material from the receiving trolley into the receiving box, ensuring more representative samples. Automation directly replaces manual operation, reducing worker workload, eliminating safety hazards, and improving work efficiency. This device features a simple structure, convenient operation, and low cost, ensuring timely and accurate sampling. By replacing manual labor with automation, it reduces worker workload and solves problems affecting work efficiency and sampling accuracy, making it highly valuable for widespread application.

[0025] The present invention will be further described in detail below with reference to the embodiments.

[0026] An automatic sampling device for powdered materials, such as Figures 1-4 The components include a control section and a receiving section. The control section includes a control box 1, a control line 2 connected to the control box 1, an electric push rod 4 connected to the control line 2, and a housing 3 with the electric push rod 4 fixed inside. The control box 1 controls the electric push rod 4 to extend and retract at time intervals. The housing 3 is connected to the chute 14 mentioned in the background section.

[0027] The receiving section includes a receiving trolley 6 connected to the stroke rod of the electric push rod 4, a trolley track 15 that cooperates with the receiving trolley 6, a soft sweeper 7 and a hard sweeper 8 located on the housing 3, a rear wheel 10 and a front wheel 11 of the trolley located at the bottom of the receiving trolley 6, a rear sweeper 9 located at the bottom of the receiving trolley 6 and behind the rear wheel 10, a front sweeper 12 located at the bottom of the receiving trolley 6 and in front of the front wheel 11, and a receiving box 13 located at the bottom of the housing 3. The receiving box 13 corresponds to the receiving trolley 6. The receiving trolley 6 and the trolley track 15 are both located inside the housing 3.

[0028] The box body 3 is made of metal. The bottom plate of the box body 3 at the connection between the box body 3 and the receiving box 13 is hollow (the bottom plate of the box body 3 above the receiving box 13 is hollow). That is, there is no bottom plate at the connection between the box body 3 and the receiving box 13, which makes it easy for the receiving trolley 6 to receive the material and then use the soft sweeper 7 and the hard sweeper 8 to sweep the material down and let it fall into the receiving box 13 through the hollow structure.

[0029] The electric push rod 4 is a pen-type electric push rod. The electric push rod 4 is fixed inside the box 3, and when the stroke rod is extended, it is located in the middle of the box 3. The front end of its stroke rod is connected to the receiving trolley 6.

[0030] The front end of the electric push rod 4 is connected to the sealing plate 5. The sealing plate 5 has a hole in the middle through which the travel rod passes, which does not affect the movement of the travel rod. The sealing plate 5 is installed inside the box 3. The receiving trolley 6 is located outside the sealing plate and is used to isolate the scattered materials from entering the space between the electric push rod 4 and the box 3.

[0031] A pair of front wheels 11 and a pair of rear wheels 10 are installed at the bottom of the receiving trolley 6. The rear wheels 10 are installed at the very rear, and the front wheels 11 are installed in the middle. Trolley tracks 15 are installed below the wheels, corresponding to the positions on the box 3. The trolley wheels are V-shaped track wheels, and the trolley tracks 15 are also V-shaped tracks, with the two having the same angle for matching use. The purpose of setting the V-shaped tracks is to prevent material from scattering onto the tracks and affecting the movement of the receiving trolley 6.

[0032] The front track sweeper 12 is located in front of the front wheel 11 of the trolley, and the rear track sweeper 9 is located behind the rear wheel 10 of the trolley. It cleans the residual material on the trolley track 15 when the receiving trolley 6 is moving to prevent mixing of samples.

[0033] This device is equipped with two sweepers to clean all the material on the receiving trolley 6 into the receiving box 13. A hard sweeper 8 (using a hard brush) is installed at the front end of the receiving trolley 6 in the direction of travel, its function being to sweep most of the material into the receiving box 13. A soft sweeper 7 (using a soft brush) is installed at the rear end of the receiving trolley 6 in the direction of travel, sweeping all remaining material on the receiving trolley 6 into the receiving box 13 to prevent the current sample from mixing with the next sample. The height of both sweepers is external and adjustable to ensure that the receiving trolley 6 is thoroughly cleaned.

[0034] In use, the device is automatically set via control box 1, such as... Figure 2 The electric push rod 4 drives the receiving trolley 6 to periodically extend into the chute 14 to sample the material flow. The control box 1 is a commercially available standard product and is not the core feature of this patent. This design does not affect the material flow within the conveying chute 14, while allowing sampling at fixed intervals. The soft sweeper 7 and hard sweeper 8 sweep all the material in the receiving trolley 6 into the receiving box 13, making the sample more representative. Automation directly replaces manual operation, reducing the labor intensity of workers, eliminating safety hazards, and improving work efficiency.
