Abstract
Description
Technical Field
[0001] The utility model relates to the field of sampling, and particularly to a sampling device for a car hopper. Background Art
[0002] Sampling machines are mainly used in the initial sampling process of ores, secondary raw materials, sintered ores, coal, coke, mine raw materials, grains, etc., and are fundamental to the sampling process. When conducting international and domestic trade transactions of coal, ores, and other materials, it is necessary to conduct strict quantitative analysis on the entire batch of goods to determine the quality of the goods. Whether the quality identification of the goods is accurate or not, the sampling process of the samples plays a very crucial role.
[0003] However, a proximity switch is installed on the sampling machine of the car hopper during use to avoid the hard contact between the sampling head of the sampling machine and the bottom of the car hopper, which may cause damage. However, the proximity switch is inconvenient to fix and is prone to wear. Summary of the Utility Model
[0004] An object of the utility model is to provide a sampling device for a car hopper that can at least solve any one of the above technical problems.
[0005] A further object of the utility model is to avoid the inconvenient fixing situation and avoid wear.
[0006] Another further object of the utility model is to improve the fixing effect and the service life of the proximity switch.
[0007] In particular, the utility model provides a sampling device for a car hopper, including a sampling cylinder, a screw rod is arranged in the sampling cylinder, a fixing frame is arranged at the feeding end of the sampling cylinder, and a fixing hole is arranged in the middle of the fixing frame;
[0008] A proximity switch, the proximity switch is installed in the fixing hole, an external thread is arranged on the outer surface of the proximity switch, a sheath and a protective head are arranged outside the proximity switch, and nut parts are arranged at opposite ends of the sheath and the protective head.
[0009] Further, the proximity switch further includes a connection hole, and a cable connecting the proximity switch is arranged in the connection hole.
[0010] Further, the nut part adopts a hexagonal nut, and the hexagonal nut is fixedly connected with the sheath and the protective head.
[0011] Further, the end of the protective head is semicircular.
[0012] Technical effects and advantages of the utility model:
[0013] The utility model fixes and protects the proximity switch by arranging a sheath and a protective head outside the proximity switch. The main body of the proximity switch passes through the fixing hole in the middle of the fixing frame, and then is clamped and fixed by the nut parts at the relative ends of the sheath and the protective head. At the same time, the proximity switch can be protected to avoid direct contact between the protective switch and the measured object, resulting in wear, thereby increasing the service life of the contact switch and the stability of the fixing.

[0024] The solution of this embodiment provides a sampling device for a carriage, including a sampling cylinder 9 and a proximity switch 100. A screw rod 901 is arranged in the sampling cylinder 9, and sampling is performed through the inner screw rod 901. A fixing frame 10 is arranged at the feeding end of the sampling cylinder 9. The fixing frame 10 is higher than the feeding end and forms a preset distance from the feeding end. A fixing hole is arranged in the middle of the fixing frame 10; the proximity switch 100 is installed in the fixing hole, so that the proximity switch 100 senses at the feeding end. When the sampling cylinder 9 performs sampling, the feeding cylinder is prevented from entering too deep through the proximity switch 100, thereby avoiding damage to the cylinder body. An external thread is arranged on the outer surface of the proximity switch 100. A sheath 101 and a head protector 103 are arranged outside the proximity switch 100. Nut portions 104 are arranged at opposite ends of the sheath 101 and the head protector 103, and a clamping portion is formed between the nut portions 104, so that it can be stably fixed on the fixing frame 10.
[0025] It should be further noted that the proximity switch 100 further includes a connection hole 106. A cable 102 connecting the proximity switch 100 is arranged in the connection hole 106, and induction data is transmitted through the cable. At the same time, an indicator light 105 is arranged, and the working state is displayed through the indicator light 105.
[0026] It should be further noted that the nut portion 104 adopts a hexagonal nut. The hexagonal nut is fixedly connected to the sheath 101 and the head protector 103, and is tightened with the thread outside the proximity switch 100 through the nut.
[0027] It should be further noted that the end of the head protector 103 is semicircular, which is convenient for passing through the piled materials.
[0028] Working principle of the present utility model:
[0029] In use, a sheath 101 and a protective head 103 capable of providing fixed protection are arranged outside the proximity switch 100. The body of the proximity switch 100 is passed through a fixing hole in the middle of the fixing frame 10, and then clamped and fixed by a nut portion 104 at the opposite ends of the sheath 101 and the protective head 103. At the same time, the proximity switch 100 can be protected to avoid direct contact between the protective switch and the object to be measured, thereby preventing wear, increasing the service life of the contact switch and the stability of fixation.
[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
