[0027] Example 1

[0028] like Figure 1-Figure 3 As shown:

[0029] A novel flexible scraper device for a belt conveyor comprises a frame 1 installed above the belt conveyor, on which a scraper 3 which can be raised and lowered is installed.

[0030] The frame 1 includes brackets 101 arranged opposite to each other. The bottom of the brackets 101 is installed on the side plate of the belt conveyor. A liftable cross brace 102 is arranged between the brackets 101. Both ends of the cross brace 102 are detachably installed on the brackets 101 arranged opposite to each other.

[0031] The bracket 101 is provided with a vertically arranged long slot 105 , and the cross brace 102 is provided with an adjusting bolt inserted into the long slot 105 near the long slot 105 , and a nut threadedly connected to the adjusting bolt is provided on the side of the bracket 101 away from the cross brace 102 .

[0032] The cross brace 102 and the bracket 101 are relatively fixed by a combination of nuts and adjusting bolts. After adjusting the height of the cross brace 102, the height of the cross brace 102 is fixed by adjusting bolts and nuts, and then the passing height of tobacco stems and tobacco materials during the conveying process is adjusted to avoid excessive accumulation of materials and overflow of the belt conveyor.

[0033] A U-shaped plate 103 is installed at the position of the cross brace 102 close to the belt conveyor. The surface of the U-shaped plate 103 close to the material removal direction is hingedly connected to the scraper 3 through a hinge 2. The bottom of the U-shaped plate 103 is located on the side of the scraper 3 close to the material incoming direction. The bottom of the U-shaped plate 103 limits the rotation direction of the scraper 3. The scraper 3 can only rotate in the material removal direction through the hinge 2, and cannot rotate in the material incoming direction.

[0034] A torsion spring is installed at the hinge between the scraper 3 and the U-shaped plate 103. The torsion spring provides a reset function for the scraper 3 and resists the thrust of the higher accumulated materials to push the scraper 3 to rotate in the material removal direction, thereby preventing the scraper 3 from rotating under the push of the materials, causing the height of the materials passing through to increase and still overflowing from the belt conveyor.

[0035] In addition to the above-mentioned technical solution of setting the torsion spring, an ear plate 104 can also be provided on the cross brace 102, and the ear plate 104 is connected to the scraper 3 through a spring 4, and the two ends of the spring 4 are detachably connected to the scraper 3 and the ear plate 104 through a bolt with a hole 5 respectively.

[0036] The hole bolts 5 are respectively installed on the scraper 3 and the ear plate 104. The connecting ends of the hole bolts 5 pass through the scraper 3 and the ear plate 104 and are connected to the ends of the spring 4. The two ends of the spring 4 are respectively detachably connected to the circular holes on the connecting ends of the hole bolts 5.

[0037] The combination of the spring 4 and the bolt with a hole 5 provides a reset function for the scraper 3, and at the same time resists the thrust of the higher accumulated materials to push the scraper 3 to rotate in the material removal direction, thereby preventing the scraper 3 from rotating under the push of the materials, causing the height of the materials passing through to increase and still overflowing from the belt conveyor.

[0038] The utility model has a simple structure and strong practicality. By arranging a liftable scraper 3 to adjust the passing height of tobacco stems and tobacco shreds during the conveying process, the conveyed tobacco stems and tobacco shreds are scraped flat, effectively solving the problem of blockage and overflow of tobacco shreds and tobacco stems.

[0039] Example 2

[0040] like Figure 4 As shown, in this embodiment, a threaded sleeve 6 is respectively provided on the scraper plate 3 and the ear plate 104 , the threaded sleeve 6 is coaxially arranged with the hole bolt 5 , and the hole bolt 5 is threadedly connected with the threaded sleeve 6 .

[0041] When in use, the threaded sleeve 6 is fixedly installed on the scraper 3 and the ear plate 104 respectively, and then the hole bolt 5 is assembled into the threaded sleeve 6. The connecting end of the hole bolt 5 passes through the scraper 3 and the ear plate 104 and is connected to the end of the spring 4.

[0042] The hole bolt 5 is threadedly connected to the threaded sleeve 6, and the hole bolt 5 is slidingly connected to the scraper 3 and the ear plate 104. The extended length of the connection end of the hole bolt 5 is adjusted by screwing the hole bolt 5. After adjustment, the end of the spring 4 is connected to the connection end of the hole bolt 5.

[0043] Except for the above technical solutions, other technical solutions not mentioned are the same as those in Example 1 and will not be described again.

[0044] In this embodiment, the operator adjusts the tension of the spring 4 to provide a reset function for the scraper 3 according to the conveying situation when the materials of different compactness are piled up too high, resist the thrust of the materials pushing the scraper 3 to rotate in the material removal direction, and avoid the situation where the materials are piled up too high and overflow from the belt conveyor.

[0045] Example 3

[0046] like Figure 5 As shown, in this embodiment, a threaded sleeve 6 is connected to the outer thread of the hole bolt 5, and the connecting end of the hole bolt 5 passes through the scraper 3 and the ear plate 104 and is connected to the end of the spring 4, and the connecting end of the hole bolt 5 is slidably connected to the scraper 3 and the ear plate 104.

[0047] A telescopic cylinder 7 is provided between the threaded sleeve 6 and the scraper 3, and a telescopic cylinder 7 is also provided between the threaded sleeve 6 and the ear plate 104. The telescopic end of the telescopic cylinder 7 is connected to the threaded sleeve 6. The extension length of the connecting end of the hole bolt 5 is adjusted by the extension of the telescopic cylinder 7, and then the tension of the spring 4 is adjusted. The operator can adjust the tension of the spring 4 according to the tightness of the conveyed material.

[0048] A control button can be connected to the telescopic cylinder 7, and the operator only needs to operate the control button to adjust the tension of the spring 4, omitting the complicated process of manually adjusting the extension length of the hole bolt 5 and then connecting it to the end of the spring 4, reducing the operating steps and reducing labor intensity.

[0049] Except for the above technical solutions, other technical solutions not mentioned are the same as those in Example 1 and will not be described again.

[0050] In this embodiment, the operator adjusts the tension of the spring 4 to provide a reset function for the scraper 3 when conveying materials with different densities that are too high and resist the thrust of the materials pushing the scraper 3 to rotate in the material removal direction, thereby preventing the scraper 3 from rotating under the push of the materials, causing the height of the materials passing through to increase and overflow from the belt conveyor.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
