Description

Technical Field

[0001] This invention relates to the field of sampling equipment for solid slag sample conveying process, and in particular to an automatic solid sampling mechanical device with a reciprocating belt head. Background Technology

[0002] In the sampling of solid slag materials, belt conveyors serve as the core transportation equipment, and material sampling during transportation is of great significance for quality control, composition analysis, and trade settlement. However, existing belt head sampling techniques still have many shortcomings: Manual sampling: Traditional manual sampling methods are not only inefficient, but also pose serious safety hazards in high-flow, high-speed conveyor belt operation environments, with sampling personnel susceptible to risks such as material splashes and mechanical injuries. Furthermore, the randomness and subjectivity of manual sampling may lead to insufficient sample representativeness, affecting the accuracy of test results.

[0003] Fixed mechanical samplers: Some companies use fixed sampling shovels or interception devices, but due to the large impact force and high flow rate of the material at the head of the belt, these devices are prone to failure due to long-term wear and cannot adapt to changes in belt speed or material flow rate, resulting in incomplete sampling or large sample deviation. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a reciprocating solid automatic sampling mechanical device with a belt head.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A belt-driven reciprocating automatic solid sampling device includes: The reciprocating motion drive mechanism is located on the outside of the belt head; The horizontally placed sampling outer sleeve has several material inlets symmetrically distributed on its upper and lower side walls. Furthermore, the sampling outer sleeve is connected to a reciprocating motion drive mechanism, enabling the sampling outer sleeve to move back and forth. The inner sampling sleeve is fitted inside the outer sampling sleeve, and several sampling slots are provided on its upper side wall; A rotary transmission gear is located at one end of the sampling inner sleeve; A rotary transmission gear plate is horizontally positioned on one side of the sampling inner sleeve, and the rotary transmission gear plate meshes with the rotary transmission gear. The sampling trough corresponds to the material inlet.

[0006] The lower part of the sampling outer sleeve is provided with a sample collection funnel, and the lower part of the sample collection funnel is provided with a sample collection trough.

[0007] A sample collection trough handle is provided on one side of the sample collection trough.

[0008] The sample collection funnel is fixedly installed on the two side walls by mounting plates on both sides.

[0009] The reciprocating motion drive mechanism includes: A power platform frame on which a power source is mounted; The lead screw is mounted on the drive shaft of the power source; A horizontally positioned balance bar, threaded onto a lead screw; The connecting rod is connected at one end to the balance bar and at the other end to the side wall of the sampling jacket.

[0010] The end of the lead screw is rotatably mounted on the transmission limit plate, which is used to limit the range of movement of the balance bar.

[0011] A PLC control box is installed on the power platform frame, and the PLC control box is connected to the start / stop control part of the power source.

[0012] A sampling platform support rod is horizontally placed at the lower part of the connecting rod. A connecting rod limiter is provided on the sampling platform support rod. The connecting rod is inserted into the connecting rod limiter, so that the connecting rod can only move back and forth along its axial direction.

[0013] The connecting rod is provided with a connecting rod limiting block, so that when the connecting rod drives the connecting rod limiting block to move back and forth, the connecting rod limiting block will be stuck at one end of the connecting rod limiter to limit the range of the connecting rod's back and forth movement.

[0014] The sampling platform support rod is fixedly installed on the two side walls by mounting plates at both ends.

[0015] The beneficial effects of this invention are: 1. This invention uses a reciprocating motion drive mechanism to push the sampling outer sleeve into the belt head. After sampling is performed using the sampling groove, the sample is discharged through the material port at the bottom of the sampling outer sleeve by the rotation of the sampling inner sleeve, thus completing the sampling process. The whole process is efficient and convenient.

[0016] 2. When sampling is required, the reciprocating motion drive mechanism pushes the sampling outer sleeve into the belt head for sampling. After sampling is completed, the sampling outer sleeve is pulled back, avoiding the risk of large particles damaging the sampling outer sleeve if it remains in the sampling area.

[0017] 3. The sampling inner sleeve of the present invention is fitted inside the sampling outer sleeve. The sampling inner sleeve rotates by meshing with the rotating transmission gear and the rotating transmission tooth plate. At the same time as rotating, the sampling and discharge of the sampling tank are completed. The design is ingenious, simple and efficient.

[0018] 4. This invention uses the head of the belt, i.e. the feeding port, to collect samples. The PLC control box can control the power source to perform timed sampling. The sampling platform itself drives the sampler to rotate, feed, and reset, realizing the automatic sample collection function. This machine has the characteristics of simple structure, easy operation and maintenance, and excellent safety protection, and is worth promoting and using. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of the invention.

[0025] like Figure 1 , Figure 4 , Figure 6 and Figure 7As shown, a reciprocating automatic solid sampling device for belt head includes: a reciprocating motion drive mechanism disposed on the outer side of the belt head; a horizontally placed sampling outer sleeve 10, on which a plurality of material inlets 19 are symmetrically distributed on its upper and lower side walls, and the sampling outer sleeve 10 is connected to the reciprocating motion drive mechanism so that the sampling outer sleeve 10 can move back and forth; a sampling inner sleeve 11, fitted inside the sampling outer sleeve 10, and having a plurality of sampling grooves 18 disposed on its upper side wall; a rotary transmission gear 12 disposed at one end of the sampling inner sleeve 11; and a rotary transmission toothed plate 14 horizontally disposed on one side of the sampling inner sleeve 11, and the rotary transmission toothed plate 14 meshes with the rotary transmission gear 12; wherein the sampling grooves 18 correspond to the material inlets 19.

[0026] like Figure 1 and Figure 2 As shown, a sample collection funnel 15 is provided at the lower part of the sampling outer sleeve 10, and a sample collection trough 16 is provided at the lower part of the sample collection funnel 15. A sample collection trough handle 17 is provided on one side of the sample collection trough 16. The sample collection funnel 15 is fixedly installed on the two side walls by mounting plates on both sides.

[0027] like Figures 1 to 4 and Figure 6 As shown, the reciprocating motion drive mechanism includes: a power platform frame 5 on which a power source 1 is mounted; a lead screw 3 mounted on the drive shaft of the power source 1; a horizontally placed balance bar 6 threaded onto the lead screw 3; and a connecting rod 7, one end of which is connected to the balance bar 6 and the other end of which is connected to the side wall of the sampling outer sleeve 10.

[0028] like Figure 3 As shown, the end of the lead screw 3 is rotatably mounted on the transmission limit plate 4, which limits the movement range of the balance bar 6. A PLC control box 2 is mounted on the power platform frame 5, and the PLC control box 2 is connected to the start / stop control section of the power source 1.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, a sampling platform support rod 13 is horizontally placed at the lower part of the connecting rod 7. A connecting rod limiter 9 is provided on the sampling platform support rod 13. The connecting rod 7 is inserted into the connecting rod limiter 9, so that the connecting rod 7 can only move back and forth along its axial direction.

[0030] like Figures 4 to 6 As shown, a connecting rod limiting block 8 is provided on the connecting rod 7, so that when the connecting rod 7 drives the connecting rod limiting block 8 to move back and forth, the connecting rod limiting block 8 will be stuck at one end of the connecting rod limiter 9 to limit the range of the connecting rod 7 to move back and forth.

[0031] like Figure 1 As shown, the two ends of the sampling platform support rod 13 are fixedly installed on the two side walls by mounting plates.

[0032] In use, the PLC control box 2 is turned on to control the power source 1 to provide power. The balance bar 6 reciprocates under the action of the lead screw 3. The transmission limit plate 4 limits the balance bar 6. The connecting rod 7 is supported by the connecting rod limiter 9 and the sampling platform support rod 13 to ensure that it moves on the same plane. The connecting rod limit block 8 limits the connecting rod 7. The sampling outer sleeve 10 is nested with the sampling inner sleeve 11 to form the head for sampling. Specifically, the sample enters the sampling groove 18 from the material port 19 at the top of the sampling outer sleeve 10. The sample is then transported by the rotating transmission gear 12 and the rotating transmission gear. Under the meshing motion of the plates 14, the sampling outer sleeve 10 and the sampling inner sleeve 11 retract while the sampling inner sleeve 11 rotates. At this time, the sampling trough 18 rotates to the lower position, corresponding to the material port 19 at the lower part of the sampling outer sleeve 10. The sample falls out and into the sample collection funnel 15. The sample collection funnel 15 collects the sample into the sample collection trough 16. The sample stored in the sample collection trough 16 is taken out by manually pulling the sample collection trough handle 17, thus completing one sampling operation. This motion logic is used to cycle through the operation. The working time of the power source 1 can be set in the PLC control box 2 to realize timed sampling.
