DETAILED DESCRIPTION

[0030] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figures 1 to 9 As shown, a secondary cleaner for an industrial conveyor belt in an embodiment of the first aspect of the utility model comprises a multi-directional fixed clamp 1, an elastic compensation mechanism, a cleaning scraper 3, a scraper mounting seat 5, a right-angle extension rod 6 and a connecting plate 11; a cleaning scraper 3 is installed on the top edge of the scraper mounting seat 5, and a plurality of positioning grooves 12 are respectively provided at both ends of the scraper mounting seat 5, and the two ends of the scraper mounting seat 5 are respectively fixedly connected to the connecting plate 11 through the positioning grooves 12, and a right-angle extension rod 6 is vertically installed on the outer end of each connecting plate 11, and a multi-directional fixed clamp 1 is sleeved on the end of the right-angle extension rod 6, and an elastic compensation mechanism is installed on the multi-directional fixed clamp 1, and the right-angle extension rods 6 on both sides are coaxially arranged, and the right-angle extension rod 6 can be extended in the running direction of the conveyor belt, and has a plurality of positioning holes, and the extended length can be freely adjusted.

[0033] In the above embodiment, it should be noted that when in use, when the sweeper is working, it is necessary to provide a pre-tightening force for the cleaning scraper 3, and by tightening the bolts under the spring compensation mechanism, an upward compensation trend is provided to the sliding module; when the polymer polyurethane scraper blade is worn, the spring will lift the scraper blade upward according to the pre-tightening force, and after wear, it is only necessary to continue to tighten the nut upwards to correct the compensation force.

[0034] This device has the function of automatically letting go of the mechanical buckle of the conveyor belt: the unique buffer structure at both ends of the product can enable the scraper blade of the sweeper to achieve multiple compensation effects of up and down and rotation, providing elastic space for letting go of the mechanical buckle of the conveyor belt. At the same time, its scraper and scraper frame structure can automatically pop open when the mechanical buckle rotates into place to achieve the function of letting go of the blade. It can effectively protect the strength of the connecting part of the conveyor belt, reduce the resistance and loss of the conveyor belt during operation, and better protect the conveyor belt than ordinary sweepers. In addition, due to the reduced scraping force on the mechanical buckle, the wear resistance of the scraper blade of the sweeper will be increased, and it has been calculated that the service life can be extended by about 13%.

[0035] This device solves the problem of interference with the roller column: With the improvement of the structure of the conveyor belt roller design, more and more unloading rollers adopt new structures. However, the reserved space of the new structure is limited, resulting in limited installation space for the traditional secondary cleaner, which makes it impossible to install or unload after installation. The unique three-section bracket design of the utility model allows the scraper blade of the cleaner to extend backward, and the scraper blade can still be placed in the best use position when there is insufficient external space. It solves the problem that most power plants and chemical plants can only install one cleaner, which leads to dust and material scattering in the conveying environment.

[0036] Example 2

[0037] like Figures 1 to 9 As shown, a secondary cleaner for an industrial conveyor belt includes all the contents of Example 1. In addition, the elastic compensation mechanism includes a compensation fixed base 2, a base column, a sleeve 9, a spring 8, an adjustment nut 13 and a sliding connection ear 16; the base column includes an upper column section 7 of a bare rod structure and a lower column section 17 of a threaded rod structure that are connected to each other, the upper end of the upper column section 7 is connected to the upper bent end of the compensation fixed base 2, the lower end of the lower column section 17 is connected to the lower bent end of the compensation fixed base 2, the sleeve 9 is slidably sleeved on the outer peripheral side of the upper column section 7, the spring 8 is sleeved on the outer peripheral side of the lower column section 17, and the bottom of the lower column section 17 is connected to the lower bent end of the compensation fixed base 2. The upper part is threadedly connected with an adjusting nut 13, the lower end of the spring 8 abuts against the adjusting nut 13, the upper end of the spring 8 abuts against the lower end surface of the sleeve 9, and the outer wall of the sleeve 9 is provided with a sliding connection ear 16 connected to the multi-directional fixed clamping ring 1; when working, the upper part of the base column is the working area of ​​the sleeve 9, and the grinding process is adopted to make it smoothly connected with the sleeve 9. The hole-shaft connection method has better stability than the traditional sweeper compensation mode, and can effectively reduce the shaking caused during work; the lower part is threaded, which cooperates with the clamping nut below to adjust the clamping degree of the spring 8; the upper and lower parts of the base column have different cooperation methods, and one column is used for multiple purposes, which cleverly reduces the installation space of the base.

[0038] Optionally, the outer side of the multi-directional fixed snap ring 1 is connected to the snap ring side ear plate 10, and the snap ring side ear plate 10 is provided with a plurality of vertically extending connection holes, and the sliding connection ears 16 are installed in two of the connection holes, such as Fig. 9 As shown, during installation, the multi-directional fixing clamp 1 and the compensating fixing base 2 can freely change the installation angle and can be adjusted to the most suitable height according to the use requirements.

[0039] Optionally, it also includes a scale 15, the lower end of the scale 15 is connected to the upper surface of the adjusting nut 13, the upper end of the scale 15 extends to the outside of the spring 8, and the scale 15 and the spring 8 are parallel to each other; the preload part is equipped with a scale 15, which can move with the adjusting nut 13 below the spring 8, and can always display the compression degree of the spring 8, and then display the compensation force of the sweeper. When the polymer polyurethane scraper blade is worn, the length of the spring 8 increases, and the size of the compensation force at that time can be observed according to the scale of the scale 15, thereby avoiding the problems of unclear indication and inability to display in real time of the existing sweeper.

[0040] Optionally, the lower edge of the scraper mounting seat 5 is provided with an inwardly concave arc structure, and the scraper mounting seat 5 has a plurality of positioning grooves 12, and the installation length of the right-angle extension rod 6 can be adjusted according to the width of the on-site rack; the arc structure design below the scraper mounting seat 5 can make the working force of the cleaning scraper 3 concentratedly transmitted to the positioning module 4, ensuring the use strength while reducing the weight of the mounting seat. The scraper mounting seat 5 is a vertical plate type, which can provide more unloading space compared to the traditional columnar or square mounting seat structure, effectively avoiding the problem of material accumulation under the cleaning scraper 3

[0041] Optionally, a positioning module 4 is further included, and the connecting plate 11 is connected to the scraper mounting seat 5 through the positioning module 4, and the positioning module 4 is an L-shaped bending structure.

[0042] The technical effects achieved by the above embodiments are:

[0043] 1. A unique elastic compensation mechanism design is adopted. This mechanism provides pre-tightening force for the scraper blade of the sweeper by tightening the bolts under the spring compensation mechanism, and can automatically lift the scraper blade upward according to the pre-tightening force when the polymer polyurethane scraper blade is worn. After wear, just continue to tighten the nut upward to correct the compensation force. This design not only ensures the optimal contact state between the scraper blade and the conveyor belt, but also compensates for the wear of the scraper blade by the elongation of the spring, thereby ensuring the durability and stability of the cleaning effect. In addition, the base column adopts different upper and lower matching methods, and one column has multiple uses, which not only reduces the installation space of the base, but also improves the structural strength of the entire sweeper;

[0044] 2. The product structure of the sweeper is highly modular, including independent modules such as the compensation fixing mechanism, the adjustment extension mechanism and the polymer polyurethane scraper. This modular design makes the replacement of each module very free and simple, thereby reducing maintenance costs. In addition, the scraper adopts a latch-type structure, which is easy and quick to replace, further improving maintenance efficiency. This modular and convenient maintenance design concept makes the utility model more advantageous in industrial applications;

[0045] 3. The curved overall scraper design is adopted. This design ensures that the scraper has equal contact surface, constant sweeping angle and constant pressure during use, thus ensuring the stability of the cleaning effect during the service life of the scraper. At the same time, the rear-adjustable scraper frame design solves the interference problem between the optimal installation position and the roller column, and effectively prevents the occurrence of material pile-up. These two design innovations not only improve the performance of the sweeper, but also enhance its adaptability and reliability in practical applications.

[0046] Example 3

[0047] like Figures 1 to 9 As shown, a secondary cleaner for an industrial conveyor belt includes all the contents of Example 2. In addition, the cleaning blade 3 is an arc-shaped sheet structure made of polymer polyurethane. The material adopts Tiptop's high-quality polymer polyurethane formula, which is wear-resistant and scratch-resistant, has a small friction coefficient and does not damage the conveyor belt.

[0048] Optionally, an aluminum frame is provided at the bottom of the cleaning scraper blade 3, and the lower end of the cleaning scraper blade 3 is vulcanized with aluminum alloy and polyurethane material to ensure a rigid connection with the mounting plate and improve the structural strength of the product.

[0049] The technical effect achieved by the above embodiment is: the cleaning scraper 3 adopts an arc-shaped forward-extending structure design, and the top surface is in contact and friction with the working surface, which can ensure that the overall force area and force angle remain unchanged after the material is worn, thereby ensuring the working stability after wear.

[0050] Example 4

[0051] like Figures 1 to 9 As shown, a secondary cleaner for an industrial conveyor belt includes all the contents of Example 3, and in addition, also includes a pin 14, and the two ends of the cleaning scraper 3 are correspondingly connected to the two ends of the scraper mounting seat 5 through the pin 14.

[0052] The technical effect achieved by the above embodiment is that the cleaning scraper 3 adopts a latch 14 structure, which is easy to operate and replace.

[0053] Example 5

[0054] like Figures 1 to 9As shown, a secondary cleaner for an industrial conveyor belt includes all the contents of Example 4, and in addition, also includes a spray assembly 18, and both ends of the spray assembly 18 are respectively plugged into the right-angle extension rods 6 at both ends.

[0055] The technical effect achieved by the above embodiment is: it is designed with a spray component 18, which can achieve the effect of flushing the conveyor belt first and then sweeping it after assembly. It has a very good effect on the working conditions where the conveying material is more viscous and the material contains a lot of fine powder; the spray component 18 can be detached and installed separately, and the spray mode can be freely changed. It is light in size and easy to install and debug. It only needs to be connected to the flushing pipeline at the working site to achieve the use effect of one sweeper and two cleanings.

[0056] In addition, other components may be installed at the reserved position to realize functions such as wind blowing, belt speed measurement, and belt surface detection.

[0057] Compared with the prior art, the utility model has the following beneficial effects:

[0058] 1. Product advantages:

[0059] 1. The curved overall scraper design provides a stable and consistent cleaning effect. The scraper has equal contact surface, constant sweeping angle, and constant pressure during use to ensure the cleaning effect within the service life of the scraper;

[0060] 2. The design of the scraper frame that can be adjusted backwards effectively solves the interference problem between the optimal installation position and the drum column, and can effectively prevent material pile-up;

[0061] 3. The bracket below the scraper adopts a vertical plate design to improve the longitudinal structural strength and prevent material pile-up;

[0062] 4. The three-section bracket design allows the bracket length to be flexibly changed according to the site conditions;

[0063] 5. The bottom of the scraper is equipped with an aluminum frame to stably and reliably fix the scraper on the bracket;

[0064] 6. The cleaning scraper blade can be replaced by one pin, which is more convenient to replace and has lower maintenance cost;

[0065] 7. Adopt tight elastic support components to ensure that the scraper always maintains ideal contact pressure on the conveyor belt, and has the characteristics of anti-shake, shock absorption, automatic compensation, etc.

[0066] 8. The tool holder assembly is modularly designed and can be replaced independently, with low maintenance cost for spare parts;

[0067] 9. High installation and adjustment freedom, unique fixing ring design, can make the fixed components find a more suitable installation point regardless of up, down, left, right, forward and reverse directions;

[0068] 10. Scale design, real-time indication of compensation torque;

[0069] 11. Excellent reliability and effect, effectively reducing costs.

[0070] 2. Applicable advantages:

[0071] 1. High reliability and long service life;

[0072] 2. Universal modular design reduces replacement costs;

[0073] Multiple positions can be adjusted according to on-site conditions, and the equipment can be used flexibly.

[0074] During operation: install the vertical back plate of the compensation fixed base 2 on the conveyor belt frame, make the top of the cleaning blade 3 fit closely with the surface of the conveyor belt, adjust the elastic compensation mechanism in the compensation fixed base 2, and use its elastic compensation function to provide working pressure for the cleaning blade 3. When the conveyor belt moves, the surface of the conveyor belt and the surface of the cleaning blade 3 produce a scraping movement to scrape off the residual material on the surface of the conveyor belt. When the polyurethane blade is worn, the compensation function of the compensation fixed base 2 can push up the cleaning blade 3 so that it still fits closely with the surface of the conveyor belt to achieve the purpose of stable cleaning.

[0075] Another feature of this product is that the installation size is flexible and it can be installed in the cleaning position where the traditional cleaner is not easy to use, such as Figure 8 , providing a better installation solution for working conditions with limited space and many position requirements.
