[0002] Coke, ore and other materials are priced by quality and are used as high-consumption and high-cost production raw materials. During the production process control, the test results of raw material quality are even the important guiding theoretical basis for some core process links. Taking the coke materials transported by automobile, train and ship in the existing technology as an example, the coke materials are large-particle materials, and there are very high requirements for the timeliness and effectiveness of the sampling of coke materials. The coke transported by automobile, train and ship is generally sampled manually.

[0003] The sampling equipment in the prior art is generally composed of a sampler, a feeder, a crusher, a reducer, a screener, a collector, etc. Among them, sampling, as an important part of the complete set of equipment, is also the part with the highest failure rate. Any change in the external environment may cause sampling failure, resulting in the loss of representativeness of the samples, thereby causing economic disputes between buyers and sellers. Therefore, it is particularly important to improve the success rate of sampling.

[0004] Currently, the sampling of coke transported by car, train or ship is generally done manually. For such large-sized materials, only a small part is shoveled from the outermost surface of the coke with a shovel, and the sample is not representative. Since manual sampling requires operators to climb into the car or train box to take samples, and the transportation of samples is also difficult, the workload of operators is very high, and the efficiency of manual sampling is low.

DETAILED DESCRIPTION

[0028] The present invention will be described in detail below in conjunction with the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0029] A sampler for large-particle materials in a transportation vehicle is disclosed in an embodiment of the present invention. Figure 1-2 As shown, it includes a connecting seat 4 and a lifting frame connecting seat 6 fixedly connected to the connecting seat 4. The connecting seat 4 is used to fix the entire device, and the lifting frame connecting seat 6 is used to fix the lifting frame. The lifting frame is a part of the lifting mechanism. The lifting mechanism is the same as the lifting mechanism used in the conventional automobile compartment sampler in the prior art, and has strong versatility, and there is no need to specially adapt the lifting mechanism and the lifting frame.

[0030] Ginseng Figure 1-2 As shown, the sampler also includes a rotary transition device telescopic rod 1, a rotary transition device 2, an external gear slewing support 5, an outer sleeve connecting rod 7, an outer sleeve 9, an inner sleeve 10 and a rotary drive motor 13. The rotary transition device telescopic rod 1, the rotary transition device 2 and the outer sleeve connecting rod 7 are connected in sequence. The outer sleeve connecting rod 7 passes through the connecting seat 4. An external gear slewing support 5 is installed between the outer sleeve connecting rod 7 and the connecting seat 4. The rotary transition device 2 can eliminate the influence of the rotation of the outer sleeve connecting rod 7 on the rotary transition device telescopic rod 1. The outer sleeve 9 can be raised and lowered by the rotary transition device telescopic rod 1.

[0031] The rotary drive motor 13 includes a power output gear, which is meshed with the external gear rotary support 5. The inner sleeve 10 is fixedly connected to the external gear rotary support 5. Specifically, the external gear rotary support 5 includes an outer ring and an inner ring, and the outer sleeve 9 is fixedly connected to the outer ring. The rotary drive motor 13 can drive the outer ring of the external gear rotary support 5 to rotate, thereby directly driving the inner sleeve 10 to rotate.

[0032] Ginseng Figure 1 or Figure 4 As shown, a cutting blade rotating shaft 16 is provided at the lower end of the outer sleeve 9, and a pair of semicircular cutting blades 12 are rotatably connected to the cutting blade rotating shaft 16.

[0033] Ginseng Figure 1-2 As shown, a rotation counter 14 is fixedly connected to the connecting seat 4, and the rotation counter 14 corresponds to the power output gear of the rotary drive motor 13. Specifically, a sensing area is provided on the power output gear, and the rotation counter 14 includes a sensing head corresponding to the sensing area. By recording the number of times the sensing area passes the sensing head, data on the number of rotations of the power output gear can be obtained.

[0034] Ginseng Figure 1As shown, an outer sleeve brake 3 matching the outer sleeve connecting rod 7 is fixedly mounted on the connecting seat 4, and the outer sleeve brake 3 has the function of limiting the rotation of the outer sleeve connecting rod 7. The outer sleeve 9 is sleeved on the inner sleeve 10, and an outer sleeve connecting shaft 8 is inserted between the outer sleeve 9 and the inner sleeve 10. The outer sleeve connecting shaft 8 is mounted on the lower end of the outer sleeve connecting rod 7, so that the outer sleeve connecting rod 7 and the outer sleeve connecting shaft 8 can rotate synchronously at the same time.

[0035] In this embodiment, the inner sleeve 10 is provided with a pair of first waist-shaped holes for the outer sleeve connecting shaft 8 to move up and down and a pair of first horizontal holes for the outer sleeve connecting shaft 8 to rotate horizontally. Figure 6 As shown, the first waist-shaped hole is used to realize the up and down movement of the outer sleeve connecting shaft 8, thereby driving the outer sleeve 9 to move up and down, and the first horizontal hole is used to realize the relative rotation of the outer sleeve 9 and the inner sleeve 10, and can realize the opening and closing of the discharge hole 11. Specifically, the first horizontal hole is seamlessly connected to the first waist-shaped hole, and both are long strip holes that match the outer diameter of the outer sleeve connecting shaft 8. A pair of first horizontal holes can allow the outer sleeve connecting shaft 8 to rotate at a maximum angle of 90 degrees, which will not affect the strength of the inner sleeve 10.

[0036] Ginseng Figure 5-6 As shown, a cutting blade flip arm 15 matching the semicircular cutting blade 12 is fixedly mounted on the inner sleeve 10, and a pair of second waist-shaped holes for the cutting blade flip arm 15 to move up and down and a pair of second horizontal holes for the cutting blade flip arm 15 to rotate in the direction, which are not marked in the figure, are provided on the inner sleeve 10. The cutting blade flip arm 15 is fixedly connected to the outer sleeve 9, and the outer sleeve 9 can drive the cutting blade flip arm 15 to rotate and rise and fall, wherein, Figure 5 The frame around the reference numeral 15 is a partial cross-sectional area showing the position of the cutting blade flip arm 15 relative to the outer sleeve 9, and does not represent an open hole structure.

[0037] Ginseng Figure 1 As shown, the outer sleeve 9 and the inner sleeve 10 are both provided with matching discharge holes 11. By controlling the relative rotation of the outer sleeve 9 and the inner sleeve 10, the overlap of the discharge holes 11 can be controlled. When the discharge holes 11 on the outer sleeve 9 and the inner sleeve 10 overlap, the discharge function can be achieved.

[0038] Ginseng Figure 4 As shown, the angle between the semicircular cutting edge 12 and the horizontal plane ranges from 30 to 75 degrees, and a pair of semicircular cutting edges 12 are cross-distributed to form a cross scissors shape.

[0039] When using, refer to Figure 3As shown, the lifting frame connection seat 6 is fixedly connected to the lifting frame of the lifting mechanism, and the sampler in this embodiment is inserted into a car, a train compartment or a ship's hold through the lifting action of the lifting mechanism. While the inner sleeve 10 is inserted, the outer sleeve 9 and the inner sleeve 10 rotate together under the drive of the rotary drive motor 13, and at the same time, a pair of semicircular cutting blades 12 at the lower part of the inner sleeve 10 rotate to a horizontal angle of 30 to 75 degrees, and the pair of semicircular cutting blades 12 are in a cross scissor shape, and the pair of semicircular cutting blades 12 are in a cutting state, so that the sampler is descending and rotating, and the material is sealed in the inner sleeve 10 by the semicircular cutting blades 12. When the sampler descends to the bottom of the compartment, the pair of semicircular cutting blades 12 are rotated to a horizontal position under pressure, so that the material cannot leak out of the inner sleeve 10, and at the same time, the sampler is pulled out of the compartment under the lifting of the external lifting mechanism connected to it, and the material collection work is completed.

[0040] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0041] The sampler of the present invention provides a new means for quality inspection of large-particle materials transported in vehicles such as cars, trains and ships, especially for large pieces of coke materials, which greatly improves the quality of sample collection and the representativeness of samples, saves costs, improves sampling efficiency, reduces the labor intensity of operators, and provides better operation safety protection for operators.
