Description

Technical Field

[0001] The invention relates to the field of mechanical technology, and in particular to a long-distance buried scraper conveyor. Background Art

[0002] The scraper conveyor is a general-purpose conveyor used in various industries such as smelting, chemical industry, environmental protection, and building materials. It has the advantages of small size, strong sealing, good rigidity, flexible process layout, convenient installation and maintenance, and multi-point feeding and multi-point unloading. However, the shortcoming of the conveying distance in certain specific fields has become an urgent concern and problem for both users and equipment manufacturers. The main factors to be considered in the long-distance scraper conveyor are the strength of the body, power transmission, speed regulation, chain tension control, and fault detection and diagnosis.

[0003] Among them, the existing long-distance buried scraper conveyor is in use, such as the attached Figure 3 , 5 As shown, a scraper is fixed on both sides of each link of the chain on the conveyor. When the scraper is driven by the chain to scrape the material, at the angle between the scraper and the connecting surface of the chain, the material obtains a larger contact area with the chain and the scraper, and at this angle, the material is also squeezed by the chain and the scraper, so that the material is easy to adhere more firmly at this angle. After long-term use, the material at the angle adheres more and more, which makes the overall weight of the chain continue to increase, and the chain sags, causing the conveyor to work unstable, and further may cause the chain to Fracture; for this reason, the existing conveyor is provided with a scraper cleaning device at its head, and the scraper is cleaned by a cleaning brush provided on the scraper cleaning device. However, since the conveyor is always in operation, in order to avoid excessive resistance to the operation of the chain caused by the cleaning device during the cleaning process, the cleaning device basically uses a brush for relatively gentle cleaning. Although this cleaning method can effectively clean most of the scraper surface, the material at the angle between the scraper and the chain is more firmly adhered, and the gentle cleaning method cannot achieve thorough cleaning, and the effect is not ideal. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art that the scraper cannot be fully cleaned, resulting in an increase in the overall weight of the chain, which is prone to sagging and breaking, and to propose a long-distance buried scraper conveyor.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A long-distance buried scraper conveyor is designed, comprising a conveyor body, each scraper of the conveyor body is provided with snap-in slots at the upper and lower ends near one end of the chain, a bead string is clamped between two of the snap-in slots, the bead string is transmission-connected with a driving module, and the driving module is used to drive the bead string to perform a rotary motion on the scraper; the bead string comprises a string rope and beads, the string rope sleeve is provided with a plurality of beads, and each of the beads is made of ferromagnetic material.

[0007] Preferably, the bottom surface of each bayonet is a convex arc surface.

[0008] Preferably, the beads are spherical and made of magnetic alloy.

[0009] Preferably, the string rope is a high-strength nylon rope.

[0010] Preferably, it also includes a scraper cleaning device, which is installed at the head of the conveyor body;

[0011] The scraper cleaning device includes two rotating shafts, a plurality of roller brushes, and a motor. A rotating shaft is arranged above and below the chain of the conveyor body respectively. The two rotating shafts are arranged parallel to the width direction of the chain. The two rotating shafts are connected to the motor in a transmission manner. The motor is used to drive the two rotating shafts to rotate synchronously. A plurality of roller brushes are coaxially fixed at both ends of each rotating shaft.

[0012] Preferably, the driving module comprises two magnets, the two magnets are fixed on two rotating shafts respectively, the magnets are arranged corresponding to every two adjacent bead strings, and the magnets and the beads attract each other.

[0013] Preferably, the coverage of each roller brush on the adjacent scraper is less than or equal to half the width of the scraper.

[0014] Preferably, it also includes a chain tension detection alarm device, which is installed below the chain at the head of the conveyor body.

[0015] Preferably, it also includes a chain tensioning device, which is installed at the tail of the conveyor body.

[0016] Preferably, it also includes an automatic chain-breaking protection device, which is installed at the tail of the conveyor body.

[0017] The long-distance buried scraper conveyor proposed by the present invention has the following beneficial effects:

[0018] A scraper cleaning device is provided, and a bead string is clamped at the connection between the scraper and the chain.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Example 1: Reference Figure 1-3 5-8, a long-distance buried scraper conveyor, including a conveyor body 1, each scraper 3 of the conveyor body 1 is provided with a bayonet 5 at the upper and lower ends near the chain 2, a bead string 6 is clamped between the two bayonet slots 5, the bead string 6 is transmission-connected to a driving module, and the driving module is used to drive the bead string 6 to perform a rotational motion on the scraper 3; by opening two bayonet slots 5, the entire bead string 6 can be limited, so that the bead string 6 can be firmly mounted on the scraper 3, avoiding the bead string 6 from being offset due to external force.

[0032] The bead string 6 includes a string rope 62 and beads 61. The string rope 62 is provided with a plurality of beads 61. Each bead 61 is made of ferromagnetic material. The magnet 44 and the beads 61 attract each other. The beads 61 are spherical and made of magnetic alloy. The spherical beads 61 have less resistance when moving. The magnetic alloy can have both magnetic properties and be more wear-resistant and stronger, so that a longer service life can be obtained. The string rope 62 is a high-strength nylon rope. The high-strength nylon rope has good toughness and a certain elasticity, which can better allow the bead string 6 to perform a rotational motion under the action of magnetic force.

[0033] The bottom surface of each bayonet 5 is convexly curved. When the bead string 6 makes a rotational motion, the movement resistance of the bead string 6 is greatly reduced, so that the movement of the bead string 6 is smoother and the wear is less.

[0034] It also includes a chain tension detection alarm device 7, which is arranged below the chain 2 at the head of the conveyor body 1. For the detection and diagnosis of faults, the scraper 3 conveyor adopts a chain tension detection alarm device 7 at the head. The scraper 3 chain 2 is continuously extended during use, and droops due to gravity. When it droops to a certain extent, it touches the photoelectric sensor and alarms. At this time, it is necessary to adjust the length of the chain 2; it also includes a chain tensioning device 8, which is arranged at the tail of the conveyor body 1, as shown in the attached Figure 2As shown, by providing a chain tensioning device 8, the chain 2 can be operated to tension the chain 2 when the chain 2 is drooping; an automatic chain breaking protection device is also included, which is installed at the tail of the conveyor body 1. The automatic chain breaking protection device is a zcs-i stall alarm device.

[0035] Example 2: Reference Figure 4 , 9 , as another preferred embodiment of the present invention, the difference from embodiment 1 is that it also includes a scraper cleaning device 4, which is installed at the head of the conveyor body 1; the scraper cleaning device 4 includes two rotating shafts 42, a plurality of roller brushes 43, and a motor 46. A rotating shaft 42 is arranged above and below the chain 2 of the conveyor body 1, respectively. Both rotating shafts 42 can be rotatably installed on the bracket 41. Both rotating shafts 42 are arranged parallel to the width direction of the chain 2. Both rotating shafts 42 are transmission-connected with the motor 46. A gear 45 is fixed at one end of the rotating shaft 42, and the two gears 45 are meshed with each other. Any rotating shaft 42 is transmission-connected with the motor 46. The motor 46 is used to drive the two rotating shafts 42 to rotate synchronously; a plurality of roller brushes 43 are coaxially fixed at both ends of each rotating shaft 42;

[0036] The coverage of each roller brush 43 to the adjacent scraper 3 is less than or equal to half of the width of the scraper 3. In this way, when the two roller brushes 43 are synchronously cleaning the scraper 3 passing below, the bristles of the two roller brushes 43 will not interfere with each other.

[0037] As attached Fig. 9 As shown, the driving module includes two magnets 44, which are respectively fixed on two rotating shafts 42. The magnets 44 are arranged corresponding to each two adjacent bead strings 6, and the magnets 44 and the beads 61 attract each other. Since the two rotating shafts 42 are connected by two gears 45, when the motor 46 is started, the two rotating shafts 42 can synchronously rotate in opposite directions. In this way, the magnets 44 arranged in the middle of each rotating shaft 42 can drive the adjacent beads 61 to move in different directions, so that the bead string 6 can perform a rotary motion as a whole. By arranging the magnets 44 on the rotating shaft 42 of the scraper cleaning device 4, the driving module can synchronously drive the bead string 6 to perform a rotary motion by means of magnetic force through the rotating shaft 42 when the scraper cleaning device 4 is working, thereby greatly simplifying the driving structure, improving reliability, and making maintenance more convenient.

[0038] The overall workflow of the present invention is as follows:

[0039] When the conveyor body 1 is working, after the motor 46 of the scraper cleaning device 4 is started, when each link of the chain 2 moves to the scraper cleaning device 4, the scrapers 3 on both sides of the link will pass between the two rotating shafts 42, and the rotating rotating shafts 42 will drive the roller brushes 43 thereon to clean most of the surfaces of the scrapers 3 on both sides;

[0040] At the same time, as attached Fig. 9 As shown, since the two rotating shafts 42 rotate synchronously in opposite directions, the magnets 44 arranged on the two rotating shafts 42 rotate synchronously in opposite directions. At this time, the top beads of the bead string 6 near the chain link on each scraper 3 will be subjected to the magnetic force of the magnet 44 on the rotating shaft 42 above it toward the front side, and the bottom beads of the bead string 61 will be subjected to the magnetic force of the magnet 44 on the rotating shaft 42 below it toward the rear side. In this way, the top and bottom of the bead string 6 will be subjected to the magnetic force toward the two sides respectively, so that the bead string 6 as a whole can rotate on the scraper 3. The bead string 6 that rotates can remove the material adhered to the angle between the scraper 3 and the chain 2, thereby ensuring that the entire chain 2 will not be too heavy due to the material adhered to the angle between the scraper 3 and the chain 2, thereby effectively reducing the wear of the chain 2 and avoiding the breakage of the chain 2.

[0041] When the chain 2 is continuously extended during use, it sags due to gravity. When it sags to a certain extent, it touches the photoelectric sensor on the chain tensioning detection alarm device 7, causing the chain tensioning detection alarm device 7 to alarm. At this time, the chain tensioning device 8 can be operated to tension the chain 2 so that the entire conveyor can operate normally.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
