[0037] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0038] It should be noted that when a part or component is considered to be "connected", "located", or "assembled" on another part or component, it may be directly disposed on the other part or component or there may be a central part or component at the same time. The terms "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0039] The utility model provides a scraper mechanism, such as Figure 1-5 As shown in 7, the scraping mechanism includes:

[0040] Hollow long handle 22;

[0041] The scraper assembly 5 is disposed at the front end of the hollow long handle 22, and includes a scraper member 51, and a cam 54 rotatably connected to the scraper member 51 and capable of resisting the scraper member 51;

[0042] The handle assembly is disposed at the rear end of the hollow long handle 22, and includes a button grip 23 and a button 42 rotatably connected to the button grip 23;

[0043] One end of the first steel wire rope L1 is connected to the button 42 , and the other end passes through the hollow long handle 22 and is connected to the cam 54 . Pressing the button 42 pulls the cam 54 to rotate through the first steel wire rope L1 , so as to drive the scraper member 51 to move along the extension direction of the hollow long handle 22 .

[0044] The scraper assembly 5 and the handle assembly based on the scraper mechanism are respectively arranged at the two ends of the hollow long handle 22, so that the scraper mechanism as a whole is a long strip structure extending along the length of the hollow long handle, and the scraper assembly 5 can be inserted into the narrow cavity of the chain oxidation furnace for cleaning. The operator presses the button 42 to drive the cam 54 to rotate through the first steel wire rope L1, and the cam 54 pushes the scraper member 51 to move forward to scrape off the crystals on the furnace wall of the chain oxidation furnace, which is convenient for manual cleaning.

[0045] Specifically, if Figure 1 and 5 As shown, a cam mounting shell 21 is formed at the front end of the hollow long handle 22 , and the cam 54 is rotatably mounted inside the cam mounting shell 21 .

[0046] Furthermore, if Figure 3 As shown, the button 42 is provided with a wire rope through hole 421, and one end of the first wire rope L1 passes through the wire rope through hole 421. The button handle 23 is provided with a fixed button shaft 422, and when the operator presses the button 42, the button 42 rotates around the button shaft 422.

[0047] like Figure 4 As shown, the shaft hole 542 of the cam 54 is movably plugged with the cam fixing shaft 55 inside the cam mounting housing 21, and the driven groove 543 of the cam 54 is movably abutted with the scraper member transmission shaft 56 of the scraper member 51. The other end of the first wire rope L1 passes around the transmission hole 541 on the cam 54.

[0048] For example, when the operator presses the button 42, the first steel wire rope L1 pulls the transmission hole 541 to drive the cam 54 to rotate around the cam fixing shaft 55, and the rotation direction is the R direction. At this time, the driven groove 543 also rotates around the cam fixing shaft 55, and pushes the scraper member 51 to move relative to the hollow long handle 22 along the first direction A, wherein the first direction A is generally the forward extension direction of the hollow long handle 22. The operator can control the scraper member 51 to scrape the crystals on the slit furnace wall of the equipment from a distance by pressing the button 42, with good cleaning effect and convenient operation.

[0049] In some embodiments, Figure 1 , Figure 2 and Figure 5As shown, the scraper mechanism provided by the embodiment of the utility model also includes a guide member 1 and a second steel wire rope L2. A scraper assembly 5 is installed at one end of the hollow long handle 22. When one end of the hollow long handle 22 slides along the extension direction of the guide member 1, the scraper assembly 5 also slides in parallel in the same direction. A plurality of mounting openings are provided on the handle body of the hollow long handle 22. The second steel wire rope L2 can be detachably mounted on the mounting openings, and the second steel wire rope L2 passes through the guide member 1. The position of the guide member 1 and the hollow long handle 22 can be locked by the second steel wire rope L2. Specifically, the scraper assembly 5 is installed in the cam mounting shell 21 at the front end of the hollow long handle 22. When the hollow long handle 22 slides along the extension direction of the guide member 1, the scraper assembly 5 also slides in parallel in the same direction. A plurality of mounting openings arranged at equal intervals are formed on the hollow long handle 22, such as Figure 2 As shown, the second steel wire rope L2 is detachably mounted on a mounting opening m on the adjustment gear 32 on the hollow long handle. n The second steel wire rope L2 is installed through the left opening 211 and the right opening 212 on both sides of the cam mounting housing 21. In addition, the second steel wire rope L2 also bypasses the guide member 1. Specifically, the second steel wire rope L2 also bypasses the left height positioning hole 122 and the right height positioning hole 121 of the guide member 1, and the relative position of the guide member 1 and the hollow long handle 22 can be locked by the second steel wire rope L2.

[0050] In some embodiments, Figure 5 As shown, the scraping mechanism provided by the embodiment of the utility model also includes an adjusting member 33, one end of the second steel wire rope L2 is connected to the adjusting member 33, and after the other end of the second steel wire rope L2 passes through the through hole of the guide member 1, the other end of the second steel wire rope L2 is wound back and connected to the adjusting member 33, and the second steel wire rope L2 can be detachably installed at a certain installation port m of the adjustment gear 32 through the adjusting member 33. n superior.

[0051] Specifically, Figure 1 and 5 As shown, the hollow long handle 22 can slide relative to the guide member 1 along the extension direction of the guide member 1, that is, the hollow long handle 22 can move relative to the guide member 1 along the second direction B. Under normal circumstances, the adjustment member 33 connected to the second wire rope L2 is detachably stuck in a certain installation port m of the adjustment gear 32. n The relative position of the guide member 1 and the hollow long handle 22 is locked. More specifically, the hollow long handle 22 can move up and down relative to the guide member 1, and when the adjustment member 33 is fixedly stuck in a certain installation opening on the adjustment gear 32, under the action of gravity, the guide member 1 has a tendency to fall in the opposite direction of the second direction B relative to the hollow long handle 22, and the total length of the second steel wire rope L2 remains unchanged, so that the second steel wire rope L2 is tightened, thereby locking the relative position of the guide member 1 and the hollow long handle 22.

[0052] More specifically, if Figure 5 As shown, a pair of left guide structures 231 and right guide structures are respectively provided on the left and right sides of the cam mounting shell 21, wherein the left guide structure 231 cooperates with the left side of the cam mounting shell 21 to form a left guide channel for the left guide member 131 to slide, and the right guide structure cooperates with the right side of the cam mounting shell 21 to form a right guide channel, so that the guide member 1 can slide relative to the hollow long handle 22 along the direction indicated by itself through the above-mentioned left guide structure 231 and right guide structure.

[0053] It should be noted that, in some optional embodiments, the guide member 1 is divided into a left guide member 131 and a right guide member 132. The left guide member 131 and the right guide member 132 are respectively located on the left and right sides of the cam mounting housing 21.

[0054] When the operator uses the scraper mechanism to clean the furnace wall inside the cavity of the chain oxidation furnace, the first direction A is generally horizontal, and the second direction B is vertical, that is, the hollow long handle 22 and the scraper member 51 therein are in a horizontal operating state, and the guide member 1 points vertically upward.

[0055] In some embodiments, the first direction A and the second direction B can be set according to actual conditions. For example, the operator tilts the hollow long handle 22 so that the scraper member 51 does not move horizontally but moves upward or downward.

[0056] In some embodiments, Figure 2 , 5 As shown in FIG. 6 , a guide hole 31 is formed on the hollow long handle 22 , and the second steel wire rope L2 passes through the guide hole 31 . The guide hole 31 is used to guide the detour of the second steel wire rope L2 .

[0057] Specifically, the guide hole 31 is provided on the hollow long handle 22, and the cam mounting housing 21 at one end of the hollow long handle 22 is provided with a left opening 211 and a right opening 212. The second steel wire rope L2 first passes through the guide hole 31, passes through the interior of the hollow long handle 22, and then passes through the left opening 211 and the right opening 212 respectively, and then passes around the left height positioning hole 122 and the right height positioning hole 121 on the left guide member 131 and the right guide member 132.

[0058] Among them, a section of the steel wire rope passing through the guide hole 31 to bypass the adjustment rod 33 is exposed, and a section of the steel wire rope from the left opening 211 to the left height positioning hole 122 of the left guide member 131 and from the right guide hole 212 to the right height positioning hole 121 of the right guide member 132 are exposed. In addition, the two sections of the steel wire rope passing through the guide hole 31 to the left opening 211 and the right opening 212 are both hidden inside the section from the cam mounting housing 21 to the hollow long handle 22.

[0059] Exemplarily, the adjustment gear 32 includes 30 adjustment gear parts arranged at equal intervals, wherein these adjustment gear parts correspond to 30 installation ports of different gears, respectively, and the spacing between each two adjacent installation ports is 7.25mm. The adjustable gear value of the adjustment gear 32 ranges from 0 to 217.5mm, wherein the adjustable gear value gradually decreases to zero along the first direction A. The length of the guide member 1 is 22mm, and the movable offset of the guide member 1 is 50-220mm, wherein the movable offset gradually decreases to 8.75mm along the second direction B. When the adjustable gear value reaches the minimum value of 0, the guide member 1 reaches the maximum displacement in the opposite direction of the second direction B, and the movable offset is 220mm at this time, indicating that when the cam mounting shell 21 is placed at the top of the guide member 1. Alternatively, when the adjustable gear value reaches a maximum value of 217.5 mm, the guide member 1 reaches a minimum displacement in the opposite direction of the second direction B, and the active offset is 8.75 mm, indicating that the bottom of the guide member 1 touches the cam mounting housing 21 .

[0060] In some embodiments, Figure 5-8 As shown, the scraping mechanism further includes a receiving hopper 11, which is connected to the guide member 1 and is located below the scraper member 51, and is used to collect dirt scraped off by the scraper member 51 when it moves along the first direction A and resets.

[0061] Specifically, the upper surface of the receiving hopper 11 is fixedly connected to the left guide member 131 and the right guide member 132 .

[0062] For example, when the operator needs to clean the crystals on the slit furnace wall of the equipment, the fixed position of the adjustment member 33 on the adjustment gear 32 can be changed, so that the operator can manually change the relative position of the guide member 1 and its receiving hopper 11 and the hollow long handle 22. Finally, the working height of the scraper assembly 5 is locked by the second steel wire rope L2, which facilitates the insertion of the receiving hopper 11 into the machine gap under the slit furnace wall of the equipment and improves the accuracy of the cleaning position of the scraper assembly 5. In fact, when the operator uses the scraper mechanism, the receiving hopper 11 does not have to be close to the bottom wall of the slit furnace wall, and the receiving hopper 11 can be suspended. Therefore, the above-mentioned "working height" does not specifically refer to the height of the scraper assembly 5 in the earth's reference system, but specifically refers to the relative working height with the guide member as the reference system. In other words, the operator can adjust the distance between the scraper assembly 5 and the receiving hopper 11 through the second wire rope L2, thereby changing the momentum of the scraped dirt when it falls into the receiving hopper 11, so as to prevent splashing pollution caused by excessive momentum of the scraped dirt.

[0063] In some embodiments, Figure 6As shown, the scraper mechanism also includes an elastic member 52, the hollow long handle 22 is formed with an abutment portion 213, and the elastic member 52 is arranged in the hollow long handle 22, one end of the elastic member 52 abuts against the abutment portion 213, and the other end of the elastic member 52 abuts against the scraper member 51 to reset the scraper member 51.

[0064] Specifically, Figure 4 As shown, the elastic member 52 is a tension spring. When the operator presses the button 42, the scraper member 51 moves relative to the hollow long handle 22 along the first direction A. At this time, the elastic member 52 is stretched and its elastic potential energy increases. When the operator lets go, the elastic potential energy of the elastic member 52 is released, pulling the scraper member 51 to reset.

[0065] For example, when the scraper member 51 is reset, the driven groove 543 is pushed to reset and rotate around the cam fixed shaft 55, and the reset rotation direction is the opposite direction of R. At this time, the transmission hole 541 is also reset and rotated around the cam fixed shaft 55, and the first steel wire rope L1 is pulled to reset the button 42. Through the above structure, the operator can control the reciprocating motion of the scraper member 51 by pressing the button, thereby improving the cleaning efficiency.

[0066] In some embodiments, the blade head structure of the scraper member is an eight-shaped opening.

[0067] Specifically, Figure 4 As shown, the blade head structure of the scraper member 51 is two symmetrical and bifurcated triangular prism structures, which are used to scrape off the oxide crystals on the wall surfaces on both sides of the slit in the chain oxidation furnace.

[0068] In some embodiments, Figure 4 , 6 As shown in FIG. 8 , a guide structure 53 is provided in the hollow long handle 22 , and a guide rod 511 is provided in the scraper member. The guide rod 511 penetrates the guide structure 53 to prevent the scraper member 51 from moving away from the first direction A pointed by the hollow long handle 22 .

[0069] Specifically, Figure 4 As shown, the scraper member 51 is provided with a rigid member 512 , and the rigid member 512 abuts against the other end of the elastic member 52 , so that the scraper member 51 can be reset under the action of the elastic member 52 .

[0070] Specifically, the rigid member 512 is a rigid cylindrical top rod, one end of which is fixedly connected to the handle of the scraper member 51, and the other end of the cylindrical top rod is provided with a spring cap 522 connected to the elastic member 52. The guide rod 511 is parallel to the handle of the scraper member 51 and is fixedly connected to the back of the blade head of the scraper member 51. Through the above structure, since the stretching direction of the rigid member 512 is consistent with the guide rod 511 and the handle, the moving or resetting direction of the scraper member 51 is determined, and the scraper member 51 is prevented from moving or resetting away from the first direction A.

[0071] In some embodiments, the scraper mechanism further includes a linear bearing 531;

[0072] like Figure 6 and 9 As shown, the main body of the guide structure 53 is a guide block 532, and the guide block 532 is provided with a bearing through hole 533, a bearing locking screw hole 534, and a left guide structure fixing screw hole 535 and a right guide structure fixing screw hole 536;

[0073] A linear bearing 531 is installed in the bearing through hole 533 . The guide rod 511 passes through the linear bearing 531 . The linear bearing 531 is used to guide the guide rod 511 to prevent the scraper member 51 from deviating from the first direction A and moving.

[0074] In some embodiments, Figure 6 and 9 As shown, the scraper mechanism also includes a bearing locking bolt, a left guide structure fixing bolt 571 and a right guide structure fixing bolt 572;

[0075] The bearing locking screw hole 534 is bolted to the bearing locking bolt to lock the linear bearing 531 in the guide block 532;

[0076] The left guide structure fixing screw hole 535 and the right guide structure fixing screw hole 536 are respectively connected to the left guide structure fixing bolt 571 and the right guide structure fixing bolt 572; wherein, the left guide structure fixing bolt 571 and the right guide structure fixing bolt 572 are respectively connected to the left guide structure fixing hole 241 and the right guide structure fixing hole 242 of the hollow long handle, so as to fix the guide structure 53 in the hollow long handle (cam mounting shell 21) to prevent the scraper member 51 from deviating from the first direction A due to the looseness of the guide structure 53.

[0077] Specifically, the linear bearing 531 is a miniature linear bearing of model LM3UU. The linear bearing 531 cooperates with the above-mentioned guide structure 53 to improve the guiding accuracy of the guide rod 511 with a fine structure.

[0078] For example, when the operator needs to clean the crystals on the furnace wall of the chain oxidation furnace, the above-mentioned scraper mechanism can be used to clean the crystals on the furnace wall of the chain oxidation furnace by the following method.

[0079] The operator first changes the fixed position of the adjustment member 53 on the adjustment gear 32 according to the inner height size of the furnace wall, and locks the relative position of the guide member and its receiving hopper 11 and the hollow long handle 22 through the second steel wire rope L2, thereby determining the working height of the scraper assembly 5 on the inner side of the furnace wall, which is convenient for inserting the scraper assembly 5 and the receiving hopper 11 into the furnace wall. Then the operator presses the button 42, and drives the cam 54 to rotate through the first steel wire rope L1, pushing the scraper member 51 forward. Then the operator releases the button 42, and the scraper member 51, under the action of the elastic member 52, pushes the cam 54 to rotate to pull back the first steel wire rope L1 and reset the button 42, so that the operator can control the reciprocating movement of the scraper member 51 by pressing the button 42 to deeply scrape the crystals on the furnace wall of the chain oxidation furnace. If the working height of the scraper assembly 5 needs to be changed later, the operator needs to first loosen the adjusting member 33, and then manually change the relative position of the guide member 1 and its receiving hopper 11 and the hollow long handle 22, and finally re-fix the adjusting member 33 to the new position on the adjusting gear 32 to lock the relative position of the guide member and its receiving hopper and the hollow long handle.

[0080] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
