Fig. 1 is a perspective view of an on-line sampler according to the present invention. Fig. 2 is a sectional view of fig. 1.
As shown in fig. 1 and 2, the on-line sampler includes a fixed box 1, a material receiving pipe 2, and a driving mechanism 3. The in-line sampler may also include a junction box 4. The in-line sampler may also include a door mechanism 5.
Fig. 3 is a perspective view of a stationary box 1 of an on-line sampler according to the present invention. Fig. 4 is a perspective view of fig. 3 from another angle.
Referring to fig. 3 and 4 in conjunction with fig. 2, the stationary box 1 is disposed obliquely. The stationary box 1 has a cavity 11 located inside, a first end 12 and an opposite second end 13, and a discharge opening 14. The stationary box 1 may further comprise a web 15.
The first end 12 is higher than the second end 13, whereby the second end 13 of the stationary box 1 is inclined downwards. The first end 12 has a first opening 121, and the first opening 121 communicates with the cavity 11. The second end 13 has a second opening 131, and the second opening 131 communicates with the cavity 11. The discharge port 14 is arranged close to the second end 13, and the discharge port 14 is used for discharging the sampling material from the discharge port 14 under the action of self gravity. The discharged sample material may be used for testing by a testing device (not shown). Preferably, the discharge hole 14 is used to supply the sampling material into the inspection apparatus, thereby improving the working efficiency. The connecting plate 15 is disposed at the first opening 121. The connecting plate 15 is convenient to be connected with the connecting box 4 and the door mechanism 5, and the structural strength of the online sampler is improved.
Fig. 5 is a perspective view of the receiving tube 2 of the on-line sampler according to the present invention. Fig. 6 is a perspective view of fig. 5 at another angle.

The receiving pipe 2 has an inner channel 21, a material inlet 22 and a material outlet 23. The material inlet 22 is communicated with the inner channel 21 and is opened on the upper side of the peripheral wall at one end of the material receiving pipe 2. Preferably, the material inlet 22 of the material receiving pipe 2 extends along the axial direction, so that the quantity of the material sampled at one time can be increased, and the sampling uniformity can be improved. The material outlet 23 is communicated with the inner channel 21 and is opened at the lower side of the peripheral wall at the opposite end of the material receiving pipe 2. Since the receiving pipe 2 is obliquely accommodated in the cavity 11 of the fixed box 1, when the receiving pipe 2 receives a sampling material through the material inlet 22, the sampling material moves toward the material outlet 23 due to gravity in the inner passage 21, falls into the cavity 11 of the fixed box 1 from the material outlet 23, and is then discharged from the discharge port 14. The material outlet 23 is always located in the cavity 11 of the fixed box 1, and the material can be discharged from the discharge hole 14 under the action of the gravity as long as the sampling material can fall into the cavity of the fixed box 1 through the material outlet 23.

In one embodiment, the driving mechanism 3 is a linear motion mechanism. Specifically, the linear motion mechanism is a cylinder or a linear motor, and accordingly the connecting shaft 31 is a piston of the cylinder or an output shaft of the linear motor.
Fig. 8 is a perspective view of an embodiment of a connection box 4 of an on-line sampler according to the present invention. Fig. 9 is a perspective view of another embodiment of a connection box 4 of an on-line sampler according to the present invention.
Referring to fig. 8 and 9 in combination with fig. 1 and 2, the connection box 4 is adapted to be fixedly disposed on a moving pipe (not shown) of the sampled material in the up-down direction D. Therefore, the sampling can be carried out on the moving pipeline with the closed parts except the discharging port.
The connecting box 4 has a cavity 41 located inside and a side inlet and outlet 42. The connection box 4 is connected to the first end 12 of the fixed box 1 at a side inlet/outlet 42, and the side inlet/outlet 42 of the connection box 4 communicates with the first opening 121 of the first end 12 of the fixed box 1.
The connection box 4 includes a main body portion 43. The junction box 4 may include an upper take-off 44 and a lower take-off 45. The connection box 4 may further include a connection plate 46. The junction box 4 may also include a transition duct 47.
In the embodiment shown in fig. 8, the side inlet and outlet 42 is provided in the main body portion 43, and the main body portion 43, the upper material receiving pipe 44 and the lower material receiving pipe 45 together form the cavity 41. The upper and lower feed pipes 44, 45 are used to arrange the junction box 4 on (e.g., by plugging, clip-fastening, etc.) the moving pipe. Preferably, the cross-sectional calibers of the upper material receiving pipe 44 and the lower material receiving pipe 45 are not larger than the cross-sectional calibers of the cavity 41 of the main body portion 43. Because the section calibers of the upper material receiving pipe 44 and the lower material receiving pipe 45 are not larger than the section calibers of the cavity 41 of the main body part 43, the materials falling through the upper material receiving pipe 44 can freely and completely fall down and pass through the cavity 41 without interference with the wall of the cavity 41 under the action of gravity, so that the uniformity of material sampling is improved, and the quantity consistency of the material sampling is facilitated. In one embodiment, the body 43 of the junction box 4 is a hexahedron. Preferably, the main body portion 43 of the junction box 4 is a rectangular parallelepiped. In fig. 8, the transition pipe 47 is disposed between the main body portion 43 and the down feed pipe 45, and tapers from the main body portion 43 to the down feed pipe 45. The transition tube 47 facilitates the pooling of material through the body portion 43.
In the embodiment shown in fig. 9, the body portion 43 is cylindrical, preferably cylindrical, to facilitate direct engagement with a cylindrical movement conduit. In this case, the body portion 43 is directly fixed to the movement path of the sampling material in the vertical direction D. The cavity 41 and the side inlet/outlet 42 are provided in the body 43. In other words, the illustrated embodiment of fig. 9 omits the upper take-off pipe 44 and the lower take-off pipe 45, thereby simplifying the structure.
In the embodiment shown in fig. 8 and 9, the connecting plate 46 encloses an annular hollow chamber 461 and encloses the side inlet/outlet 42, the connecting plate 46 is fixed around the side inlet/outlet 42, and the connecting plate 46 is connected to the first end 12 of the stationary box 1. In the embodiment shown in fig. 2, the connecting plate 46 is fixedly connected to the web 15. The connecting plate 46 facilitates the oblique arrangement of the stationary box 1.
Note that in some embodiments, the connection box 4 can be omitted. For example, the moving pipe is directly provided with an opening so that the material inlet 21 of the receiving pipe 2 extends into the opening and material sampling is performed. For another example, the moving pipeline is open-ended, and the material inlet 21 of the receiving pipe 2 is directly below the open end of the moving pipeline for sampling the material.
Fig. 10 is a perspective view of the door mechanism 5 of the on-line sampler according to the present invention.
Referring to fig. 10 in conjunction with fig. 2, the door mechanism 5 is disposed between the connecting plate 46 and the fixed box 1. The door mechanism 5 includes a door cover 51. The door mechanism 5 may further comprise a mounting plate 52, two opposing fixed seats 53 and a pivot shaft 54. The door mechanism 5 may also include a guard plate 55.
The door cover 51 can pivot to open or close the hollow chamber 461 of the connecting plate 46. The door 51 can cover a through hole 521 of the mounting plate 52 when the on-line sampler is not sampling, and further the door 51 and the mounting plate 52 together close the hollow cavity 461 of the connecting plate 46 from one side, so as to prevent the material from jumping (i.e. the material jumps into the cavity 11 of the fixed box 1 through the side inlet/outlet 42 and the hollow cavity 461 and then is discharged through the outlet 14, i.e. the material is not taken out when the material receiving pipe 2 is sampling, and thus the detection data is inaccurate). The mounting plate 52 is fixed to the connecting plate 46, and the mounting plate 52 is fixed to the connecting plate 46 by, for example, screwing, welding, bonding, or the like, preferably by screwing, such as a screw or a combination of a screw and a nut, for easy attachment and detachment. The mounting plate 52 has a through hole 521, and the through hole 521 is used for communicating with the hollow cavity 461 of the connecting plate 46. Two opposing anchor mounts 53 are provided on the mounting plate 52. Two fixing seats 53 are provided to which opposite sides of the door cover 51 are pivotally mounted. Specifically, each of the fixing seats 53 has one pivot hole 531. A pivot shaft 54 is provided on the door cover 51, the pivot shaft 54 pivotally penetrates the two pivot holes 531. The number of pivot shafts 54 may be one or two. If one pivot shaft 54 is adopted, two ends of one pivot shaft 54 can respectively penetrate into the two pivot holes 531 in a pivoting manner; if two pivot shafts 54 are used, one end of one of the pivot shafts 54 is pivotally inserted into one of the pivot holes 531, and one end of the other pivot shaft 54 is pivotally inserted into the other pivot hole 531. The shielding plate 55 is located at a side of the two fixing bases 53 facing away from the through hole 521 of the mounting plate 52, and the shielding plate 55 serves to limit a pivoting angle of the door cover 51 to prevent the door cover 51 from colliding against the connection plate 46. Note that, in the example shown in fig. 2, the mounting plate 52 of the door mechanism 5 is fixed to the connecting plate 46 together with the linking plate 15. Similarly, the mounting plate 52 and the connecting plate 15 can be fixed to the connecting plate 46 by screwing, welding, bonding, etc., preferably by screwing, such as screws or a combination of screws and nuts, for easy assembly and disassembly.
Note that the pivotal arrangement of the door cover 51 is not limited to the example shown in fig. 10 and 2, and may be suitably changed depending on the case of the constituent parts of the on-line sampler. For example, the door cover 51 may be provided directly on the connection box 4, and further, the door cover 51 may be provided directly on the connection plate 46.
Next, a sampling operation will be described based on the entire structure of fig. 2.
Referring to fig. 2, when the online sampler samples, the driving mechanism 3 drives the material receiving pipe 2 to move in the cavity 11 of the fixed box 1, the material receiving pipe 2 passes through the first opening 121, passes through the through hole 521 of the mounting plate 52, and pushes the door cover 51 open, the material receiving pipe 2 enters the hollow cavity 461 of the connecting plate 46 of the connecting box 4, then the material receiving pipe 2 passes through the side inlet 42 of the connecting box 4 and enters the cavity 41 of the connecting box 4, and when the material receiving pipe 2 just enters the cavity 41, part of the material falls into the material inlet 22 of the material receiving pipe 2 when the material falls in the cavity 41; subsequently, the receiving tube 2 moves from one side of the cavity 41 to the other side (from the left side to the right side in fig. 2) and then from the other side to the starting position (from the right side to the left side in fig. 2), and a sampling process is completed. The utility model discloses connect material pipe 2 in the in-process that removes in cavity 41 with cavity 41 in the middle part, marginal part's material all gathered the sample, improved the homogeneity of sampling like this. Then, the sampled material descends to the material outlet 23 of the material receiving pipe 2 through the inner channel 21 of the material receiving pipe 2 by utilizing the self gravity, falls into the cavity 11 of the fixed box 1 through the material outlet 23, and finally the material in the cavity 11 is discharged from the discharge hole 14, so that the whole sampling operation is completed. After the sampling is completed, the driving mechanism 3 drives the material receiving pipe 2 to exit the cavity 41 of the connection box 4, the side inlet and outlet 42 of the connection box 4, and the hollow cavity 461 of the connection plate 46 of the connection box 4 in sequence, the door cover 51 pivots reversely by its own weight to cover the through hole 521 of the mounting plate 52, and the material receiving pipe 2 exits the first opening 121 and is accommodated and stopped in the cavity 11 of the fixed box 1. The door 51 can prevent the falling material in the cavity 41 from flowing into the cavity 11 to be mixed with the sampling material, so that the sampling uniformity is reduced.
Note that the material is not limited to grain, nor to particulate matter, as long as the material can be sampled by the online sampler.
The above detailed description describes exemplary embodiments, but is not intended to limit the combinations explicitly disclosed herein. Thus, unless otherwise specified, various features disclosed herein can be combined together to form a number of additional combinations that are not shown for the sake of brevity.
