Description

Technical Field

[0001] The utility model belongs to the technical field of heavy medium shallow trough separators, and in particular relates to a slideway used for heavy medium shallow trough separators. Background Art

[0002] Heavy medium shallow trough separator is generally used in coal mining industry. It is one of the important equipment for coal preparation. Its working principle is to sort materials according to the characteristics of different specific gravities. Specifically, heavy medium shallow trough separator is a trough sorting equipment that works according to the sinking and floating principle of materials with different specific gravities in heavy medium suspension. Block materials are sorted in a trough filled with heavy medium suspension, and lighter materials rise to the liquid surface and are discharged through the weir surface. High specific gravity materials that sink to the bottom are lifted to the discharge port by the gangue scraper, thereby obtaining two products with different specific gravities. The heavy medium shallow trough separator has a slideway, which supports and limits the scraper sprocket. The traditional slideway is a metal slideway, and its performance characteristics are large running resistance and fast wear. The metal slideway will generate noise and vibration during the flow of materials, which will not only affect the working environment of the operator, but also may cause damage to other parts of the equipment; and when the metal slideway is worn, the maintenance personnel cannot quickly and timely detect the worn parts, resulting in the problem of difficult maintenance, time-consuming and labor-intensive. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a slide for a heavy medium shallow trough separator, so as to solve the problem that the existing metal slide will generate noise and vibration during the material flow process, which will not only affect the working environment of the operator, but also may cause damage to other parts of the equipment; and when the metal slide is worn, the maintenance personnel cannot quickly and timely detect the worn parts, resulting in the problem of difficult maintenance, time-consuming and labor-intensive.

[0004] To achieve the above objectives, the utility model adopts the following technical solution: a slide for a heavy medium shallow trough sorter, comprising a lower slide and an upper slide, the lower slide and the upper slide having the same structure and being relatively arranged on the side walls of a sorting machine body, a power mechanism being installed in the sorting machine body, the power mechanism being connected to a sprocket mechanism through a chain transmission, the lower slide comprising a metal body and a detachable polyurethane block, the bottom surface of the metal body being provided with a connecting edge and a snap-on edge, the detachable polyurethane block being provided with a groove body adapted to snap-on the connecting edge and the snap-on edge, the connecting edge and the detachable polyurethane block being provided with bolt hole one and bolt hole two which are positioned oppositely, a wear detection component being provided in the side of the detachable polyurethane block which is away from the metal body, the wear detection component comprising an antenna and an NFC chip, the wear detection component being wirelessly connected to a handheld NFC device.

[0005] The beneficial effects of the utility model are as follows: the detachable polyurethane blocks can be disassembled and replaced separately, which effectively reduces the use cost compared with the metal body and the replacement of the detachable polyurethane blocks as a whole; the low friction coefficient and shock absorption effect of the detachable polyurethane blocks can reduce the resistance encountered when the chain moves, and reduce vibration and noise to protect the equipment; when the detachable polyurethane blocks are worn and the wear detection components leak out and are damaged, the maintenance personnel can hold the NFC device and quickly detect and determine the position of the corresponding detachable polyurethane blocks through signal feedback.

[0006] In order to quickly and stably connect the metal body with the detachable polyurethane block;

[0007] As a further improvement of the above technical solution: the connecting edge is a long strip convex block structure, and bolts are installed in the second bolt hole and the first bolt hole.

[0008] The beneficial effects of this improvement are: the detachable polyurethane block and the metal body can be firmly connected by bolts, and the detachable polyurethane block can be quickly disassembled and replaced after being worn, thereby improving maintenance efficiency.

[0009] In order to ensure the connection strength between the metal body and the removable polyurethane block;

[0010] As a further improvement of the above technical solution: there are multiple clamping edges, which are arranged at equal intervals at the bottom of the metal body.

[0011] The beneficial effect of this improvement is that a plurality of snap-fitting edges cooperate with the connecting edges to form a grid-like structure, so that the metal body and the detachable polyurethane block are firmly limited in the horizontal direction, effectively ensuring the connection strength between the metal body and the detachable polyurethane block.

[0012] In order to quickly load and unload the lower and upper slideways;

[0013] As a further improvement of the above technical solution: the two bolt holes penetrate through two sides of the detachable polyurethane block.

[0014] The beneficial effect of this improvement is that the bolt inserted in the second bolt hole can simultaneously fix the lower slide and the upper slide as a whole to the sorting machine body, and the lower slide and the upper slide can be quickly and stably installed on the sorting machine body through bolt connection.

[0015] In order to comprehensively and effectively detect the wear state of the detachable polyurethane block through the setting of the wear detection component;

[0016] As a further improvement of the above technical solution: the NFC chip is arranged parallel to a side of the detachable polyurethane block facing away from the metal body.

[0017] The beneficial effect of this improvement is: when any bottom surface part of the detachable polyurethane block is worn for a long time so that the wear detection component is exposed, the antenna is worn off by the moving chain, and the wear detection component is damaged and cannot feedback the signal. The inspector holding an electronic device with NFC function can quickly and directly determine the position of the excessively worn lower and upper slides.

[0018] In order to effectively increase the signal feedback area of ​​the wear detection component;

[0019] As a further improvement of the above technical solution: the NFC chip is bent in a U-shape and arranged in a detachable polyurethane block, and the NFC chip is electrically connected to the antenna.

[0020] The beneficial effect of this improvement is that the NFC chip bent in a U-shape can fully increase the signal feedback area of ​​the wear detection component, making it easier for personnel to detect.

[0021] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0029] Embodiment 1:

[0030] like Figure 1—5 shows: a slide for a heavy medium shallow trough separator, comprising a lower slide 4 and an upper slide 5, the lower slide 4 and the upper slide 5 having the same structure and being arranged on the side wall of a separator body 1 in an upper and lower direction opposite to each other, a power mechanism 2 being installed in the separator body 1, the power mechanism 2 being connected to a sprocket mechanism 3 through a chain drive, the lower slide 4 comprising a metal body 41 and a detachable polyurethane block 42, the bottom surface of the metal body 41 being provided with a connecting edge 43 and a snap-on edge 45, the detachable polyurethane block 42 being provided with a groove body adapted to snap-on the connecting edge 43 and the snap-on edge 45, the connecting edge 43 and the detachable polyurethane block 42 being provided with a groove body adapted to snap-on the connecting edge 43 and the snap-on edge 45, A bolt hole 1 44 and a bolt hole 2 46 are provided, which are opposite to each other. A wear detection component 47 is provided on the side of the detachable polyurethane block 42 facing away from the metal body 41. The wear detection component 47 includes an antenna 471 and an NFC chip 472. The wear detection component 47 is wirelessly connected to a handheld NFC device. The detachable polyurethane block 42 can be disassembled and replaced separately, which effectively reduces the use cost compared with the replacement of the metal body 41 and the detachable polyurethane block 42 as a whole. The low friction coefficient and shock absorption effect of the detachable polyurethane block 42 can reduce the resistance of the chain when it moves, and reduce vibration and noise to protect the equipment.When the detachable polyurethane block 42 is damaged due to wear and tear, resulting in leakage of the wear detection component 47, the maintenance personnel can hold the NFC device and quickly detect and determine the position of the corresponding detachable polyurethane block 42 through signal feedback. The connecting edge 43 is a long strip convex block structure, and bolts are installed in the bolt hole 2 46 and the bolt hole 1 44. The detachable polyurethane block 42 and the metal body 41 can be firmly connected by bolts, and the detachable polyurethane block 42 can be quickly disassembled and replaced after the detachable polyurethane block 42 is worn, thereby improving the maintenance efficiency. The number of the snap-in edges 45 is multiple, and they are equidistantly arranged at the bottom of the metal body 41. The multiple snap-in edges 45 cooperate with the connecting edges 43 to form a grid structure, so that the metal body 41 and the detachable polyurethane block 42 are firmly limited in the horizontal direction, effectively ensuring the connection strength between the metal body 41 and the detachable polyurethane block 42, and the bolt hole 2 46 runs through both sides of the detachable polyurethane block 42. The bolts inserted in 46 can simultaneously fix the lower slide 4 and the upper slide 5 as a whole on the sorting machine body 1, and the lower slide 4 and the upper slide 5 are quickly and firmly installed on the sorting machine body 1 in the form of bolt connection. The NFC chip 472 is arranged parallel to the side of the detachable polyurethane block 42 facing away from the metal body 41. When any bottom surface of the detachable polyurethane block 42 is worn for a long time, causing the wear detection component 47 to be exposed, the antenna 471 is worn off by the moving chain, and the wear detection component 47 is damaged and cannot feedback the signal. The inspection personnel holding the electronic device with NFC function can quickly and directly determine the position of the excessively worn lower slide 4 and the upper slide 5. The NFC chip 472 is arranged in the detachable polyurethane block 42 in a U-shaped bend. The NFC chip 472 is electrically connected to the antenna 471. The NFC chip 472 arranged in a U-shaped bend can fully increase the signal feedback area of ​​the wear detection component 47, which is convenient for personnel to detect. ;

[0031] The working principle of the present technical solution is as follows: the power mechanism 2 drives multiple sprocket mechanisms 3 to rotate through the chain, and the rotating sprocket mechanisms 3 provide stable support for the chain. When the chain moves, it is supported and limited by the lower slide 4 and the upper slide 5; the low friction of the detachable polyurethane block 42 can reduce the resistance encountered when the chain moves, and the detachable polyurethane block 42 can play a role in buffering and absorbing energy, thereby reducing the vibration generated when the chain moves; when the detachable polyurethane block 42 is worn for a long time, causing the wear detection component 47 to be exposed, the antenna 471 is worn off by the moving chain, and the NFC chip 472 cannot receive or send signals at this time. When the inspector holds an electronic device with NFC function and moves it along the lower slide 4 and the upper slide 5 one by one, when the electronic device moves above the damaged wear detection component 47, the electronic device lacks corresponding signal feedback, and the operator can quickly and directly determine the position of the excessively worn lower slide 4 and the upper slide 5.
