[0002] The gantry truck sampler is a kind of coal sampling equipment, which is mainly composed of feeding system, sample grading system, sampling system, control system and other parts. When sampling the coal on the train, first run the train into the gantry sampler, then insert the sampling head into the coal in the cargo box, and then start the sampling system to collect it. The common sampling system generally forms sampling through the auger feeding equipment. The entire auger sampling component is also called the sampling head, which is one of the most important components in the gantry sampler.

[0003] However, when using the above-mentioned sampling head, it was found that the auger rod is prone to friction with coal during long-term use, and its wear rate is relatively fast. Therefore, the auger rod needs to be replaced regularly. During the replacement process, in order to ensure the sealing, the auger rod and the outer shell are generally fixed by multiple fastening bolts. This installation method leads to slow disassembly and replacement in the later stage, which makes it difficult to quickly disassemble and replace, affecting the sampling efficiency.

[0004] Therefore, it is necessary to provide a new sampling head structure of a door-type automobile sampler to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1-Figure 8The sampling head structure of the door-type automobile sampler includes: a first sleeve 1 and a second sleeve 2, which are connected by a flange, so that the longer sleeve can be split into two shorter sleeves to facilitate subsequent cleaning and maintenance of the two, and a discharge pipe is fixedly installed on the first sleeve 1 to discharge the collected sample, and a cover 3 is provided on the top of the first sleeve 1, and a connecting shaft 19 is rotatably installed at the bottom of the cover 3, and an auger 4 is connected to the bottom of the connecting shaft 19 through a flange, and the auger 4 is located in the first sleeve 1 and the second sleeve 2, and two rectangular sockets 5 are provided on the top of the cover 3, and two fixing blocks 6 are fixedly installed on the outer wall of the first sleeve 1, and two A plug-in strip 7 is fixedly installed on the top of the fixing block 6. The two plug-in strips 7 respectively penetrate the two rectangular sockets 5 and are slidably connected with the corresponding rectangular sockets 5. A transverse card slot 8 is provided on the side away from each other of the two plug-in strips 7. Square columns 9 are fixedly installed on both sides of the cover 3. Sliding plates 10 are slidably installed on the two square columns 9. A transverse card head 11 is fixedly installed on the side where the two sliding plates 10 are close to each other. The side where the two transverse card heads 11 are close to each other extends into the two transverse card slots 8 respectively. By plugging the plug-in strip 7 and the rectangular socket 5, and the transverse card slot 8 and the transverse card head 11, a stable connection can be formed between the cover 3 and the first sleeve 1, and for the convenience of People replace the auger 4. A wedge block 16 is fixedly installed on the side where the two sliding plates 10 are away from each other. A squeezing and pushing mechanism is provided on the cover 3, and the squeezing and pushing mechanism is adapted to the wedge block 16. The squeezing and pushing mechanism includes a protective sleeve 12, which is fixedly installed on the top of the cover 3. An internal threaded sleeve 13 is threadedly sleeved on the protective sleeve 12, and an extrusion sleeve 14 is sleeved on the internal threaded sleeve 13. A plurality of stabilizing rods 15 are fixedly installed on the outer wall of the internal threaded sleeve 13. The ends of the plurality of stabilizing rods 15 are fixedly connected to the inner wall of the extrusion sleeve 14. An inclined surface is provided at the bottom of the extrusion sleeve 14, and the inclined surface is adapted to the wedge block 16. A side baffle 17 is fixedly installed on the ends of the two square columns 9 away from each other. The two square columns 9 are both sleeved with a pull-back spring 18. The ends of the two pull-back springs 18 that are close to each other are fixedly connected to the two sliding plates 10, and the ends of the two pull-back springs that are away from each other are fixedly connected to the two side baffles 17. The extrusion sleeve 14 is driven to rise or fall by rotating the internal threaded sleeve 13. When it rises, it is separated from the wedge block 16, so that under the action of the pull-back spring 18, the transverse positioning head 11 is automatically brought out of the transverse positioning groove 8 to quickly complete the separation of the cover 3 and the first sleeve 1. When it descends, the oblique surface at the bottom of the extrusion sleeve 14 and the wedge block 16 can be used to automatically bring the transverse positioning head 11 into the transverse positioning groove 8, thereby improving the disassembly and replacement speed.

[0025] In the above manner, in order to drive the auger 4 to rotate, a driving motor is fixedly installed on the top of the cover 3 , the output shaft of the driving motor is fixedly connected to the top of the auger 4 , and the driving motor is located in the protective sleeve 12 .

[0026] A male thread is provided on the outer wall of the protective sleeve 12 , and a female thread is provided on the inner wall of the internal thread sleeve 13 . The female thread is screwed together with the male thread to realize the rising and falling of the extrusion sleeve 14 .

[0027] The working principle of the sampling head structure of the door-type automobile sampling machine provided by the utility model is as follows:

[0028] In the initial state, the two return springs 18 are in a stretched state;

[0029] When the auger 4 is seriously worn and needs to be replaced, the internal threaded sleeve 13 can be rotated counterclockwise. Driven by the stabilizing rod 15, the extrusion sleeve 14 starts to rise, thereby slowly removing the pressure on the wedge block 16. During the pressure relief process, the stretched return spring 18 gradually pulls back and resets, so that the two transverse positioning heads 11 gradually move out of the corresponding transverse slots 8. After the transverse positioning heads 11 are completely moved out of the transverse slots 8, the plug-in strip 7 loses the foreign object positioning, and then the cover 3 is directly pulled out of the first sleeve 1;

[0030] Then, the auger 4 is removed from the connecting shaft 19 and replaced with a new auger 4. After the replacement, the auger 4 is directly inserted into the first sleeve 1, and finally the two plug strips 7 are respectively inserted into the two rectangular sockets 5 until the first sleeve 1 contacts the cover 3. Then, the internal threaded sleeve 13 is rotated clockwise, and the extrusion sleeve 14 rotates and descends accordingly. When the inclined surface at the bottom contacts the inclined edge of the wedge block 16, the wedge block 16 begins to be squeezed. At this time, the two wedge blocks 16 move in a direction close to each other, and the pull-back spring 18 is stretched again until the two horizontal positioning heads 11 are inserted into the corresponding horizontal card slots 8, and the auger 4 is completely replaced.

[0031] In subsequent use, the first sleeve 1 and the second sleeve 2 can be separated to separate the longer sleeve into two shorter sleeves, and then the two can be conveniently cleaned.

[0032] Compared with the related art, the sampling head structure of the door-type automobile sampler provided by the utility model has the following beneficial effects:

[0033] The utility model provides a sampling head structure of a door-type automobile sampler, by plugging the arranged plug-in strip 7 with the rectangular socket 5, a horizontal limit can be formed between the sealing cover 3 and the first sleeve 1, and then by plugging the transverse clamping groove 8 with the transverse clamping head 11, a vertical limit can be formed between the sealing cover 3 and the first sleeve 1, thereby completing the assembly and fixation of the two, and at the same time, by rotating the internal threaded sleeve 13, the auger 4 can be quickly taken out from the first sleeve 1, thereby forming a rapid replacement process for the auger 4, and will not bring a significant impact on the normal sampling work.
