[0041] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0042] like Figure 1 As shown, the utility model provides a chute scraper device, comprising: a swivel arm 2, a support seat 1 and a power device. In this embodiment, the swivel arm 2 is not a straight component, but a bent portion 23 is provided between the two ends of the swivel arm 2. By drilling a hole in the bent portion 23, the bent portion 23 is rotatably connected to the support seat 1 through a rotating shaft. A cutter head is installed at one end of the swivel arm 2, and the accumulated material in the chute is removed by the cutter head; the end of the swivel arm 2 away from the cutter head is rotatably connected to the movable end of the power device.

[0043] In some feasible embodiments, the power device uses a hydraulic cylinder 6, and a hydraulic cylinder 6 with a diameter of 65mm and a telescopic length of 450mm is selected, and a hydraulic pump station 5 is set to provide power for the hydraulic cylinder 6, and the hydraulic pump station 5 is also installed on the slide housing 8. The hydraulic cylinder 6 is driven to move by the output power of the hydraulic pump station 5, and the movable end of the hydraulic cylinder 6 extends to drive the rotating arm 2 to rotate around the connection with the support seat 1. During the rotation process, the cutter head cleans the accumulated materials in the slide; the hydraulic cylinder 6 contracts and drives the slide scraper device to return to its position, that is, drives the rotating arm 2 to return to its position, and completes a scraping process. It can be imagined that the model of the hydraulic cylinder 6 can be selected as needed, for example: it can be adaptively adjusted according to the size of the slide to be scraped, the position set on the slide, or the size of the matching parts, etc., and no further restrictions are made here.

[0044] This chute scraper device can be used in ports, mines, bulk cargo belts and other transportation equipment. It is installed on the chute of the transfer tower of the belt transportation system, which solves the problem of material accumulation on the chute receiving plate, which requires personnel to enter the chute to clear the material, causing serious safety hazards. When the chute is blocked, the extension of the hydraulic cylinder drives the rotating arm 2 to rotate and scrape off the accumulated material; the extension and contraction of the hydraulic cylinder 6 drives the rotation of this device to complete the scraping operation and achieve the scraping effect. The accumulated material can be cleared under the premise of ensuring safety, and 24-hour work is achieved. The number of shutdowns required for manual cleaning is reduced, the cleaning efficiency and overall work efficiency are improved, and the major safety risks caused by personnel entering the chute to clean the material are avoided, saving labor. The structure is simple and reliable, and the force is evenly distributed.

[0045] An opening is provided on the top shell of a conventional chute. During on-site operation, a chute scraper is installed at the opening on the top of the chute, wherein one end of the rotary arm 2 provided with a cutter head extends into the chute, so that the rotary arm 2 scrapes the accumulated material in the chute during the rotation process. At the same time, the end of the power device away from the rotary arm 2 is fixed to the upper beam of the chute; it is conceivable that a frame can be separately provided in the chute scraper to install the power device, which is not limited here.

[0046] In the above scheme, the rotating arm 2 of the chute scraper device has a knife head, which can be extended into the chute to scrape off the accumulated material in the chute, reducing the impact of the accumulated material on the normal operation of the chute and further extending the service life of the chute; the chute scraper device is directly installed on the chute, and the installation and setting method is simple.

[0047] like Figure 1 , Figure 5 As shown, in a preferred solution, the swivel arm 2 includes: a first swivel shaft 21 and a second swivel shaft 22. In this embodiment, the length of the first swivel arm 2 is less than that of the second swivel arm 2. The first swivel shaft 21 and the second swivel shaft 22 are connected at an angle. A bending portion 23 is formed at the connection between the first swivel shaft 21 and the second swivel shaft 22, and the support seat 1 is connected through the bending portion 23. The end of the first swivel shaft 21 away from the second swivel shaft 22 is rotatably connected to the hydraulic cylinder 6, and the lower end of the second swivel shaft 22 away from the first swivel shaft 21 is equipped with a cutter head.

[0048] In some feasible embodiments, the slewing arm 2 is made of two iron plates with a thickness of 20 mm and placed side by side to form the main structure, that is, the first slewing axis 21 and the second slewing axis 22 are an integrated structure, with an overall length of 700 mm, a width of 180 mm, and a height of 1022 mm. A hole is punched on the upper first slewing axis 21, and a rotation connection with the hydraulic cylinder 6 is realized through the pin shaft of the hydraulic cylinder 6, wherein the pin shaft size of the hydraulic cylinder 6 is 55 mm. At the same time, in order to realize the connection with the cutter head, a connecting plate is also provided on the lower end face of the lower second slewing axis 22, and the connecting plate is connected to the cutter head through 12 bolts with a diameter of 20 mm; and a 10 mm thick iron plate is used as a reinforcing rib between the connecting plate and the side wall of the second slewing axis 22 for fixing, and the length of the reinforcing rib is 260 mm and the height is 200 mm. The bending portion 23 is rotatably connected to the support seat 1 through the slewing support main shaft, wherein the slewing support main shaft is a rotating shaft that plays a role of slewing connection, and the diameter is 80 mm. The angle between the pin of the upper hydraulic cylinder 6 and the main axis of the slewing support and the horizontal plane is 45 degrees.

[0049] In the above scheme, the bending portion 23 of the swivel arm 2 is rotatably connected to the support seat 1, the first swivel axis 21 and the second swivel axis 22 are set at an angle, and the lever principle is used to design that when the hydraulic cylinder 6 extends and retracts, it can drive the swivel arm 2 to rotate around the connection with the support seat 1, so that the cutter head moves along an arc trajectory in the internal space of the slide pipe, thereby completing the scraping operation and achieving the scraping effect.

[0050] like Figure 1-4 As shown, in the preferred scheme, the support base 1 is fixed on the slide casing 8, and the support base 1 includes: a frame 11 and a bottom plate 12. The frame 11 is arranged on one side of the opening of the slide casing 8, and the bottom plates 12 are respectively arranged on the bottom end surfaces on both sides of the frame 11. The bottom plates 12 on both sides are symmetrically arranged about the central axis of the frame 11, and the frame 11 is installed at the opening position of the slide casing 8 through the bottom plate 12.

[0051] In some feasible embodiments, the frame 11 is made of a square tube with a size of 120mm to form a "door" type frame 11, and the length of the frame 11 is 800mm, the height is 480mm, and the width is 480mm; the bottom plate 12 is made of a 10mm thick iron plate, with a length of 400mm and a width of 200mm; an inclined plate reinforcement rib is set between the bottom plate 12 and the side wall of the frame 11 on the side close to the slewing arm 2 for fixing, and the inclined plate reinforcement rib is made of an iron plate with a height of 160mm, a length of 220mm, and a thickness of 10mm. It can be imagined that the size of each component in the support seat 1 is not limited to the above size, and can be adaptively adjusted according to the size of the matching components and the size of the chute required for scraping, and no further limitation is made here.

[0052] In the above scheme, by setting a frame 11 on one side of the opening of the chute shell 8 and installing a base plate 12 on the bottom end surfaces of both sides of the frame 11, the entire support seat 1 has a stable structure and can effectively support the scraper device, ensuring the stability during the scraping process and reducing the risk of equipment damage caused by vibration or impact; the stable support seat 1 can ensure that the chute scraper device will not shake or fall off during operation, thereby improving work safety.

[0053] like Figure 1-4 As shown, in the preferred solution, a bearing seat 7 is arranged on one side of the frame 11 close to the opening of the slide pipe, and a connecting hole is opened on the bearing seat 7, so that the slewing arm 2 is connected to the bearing seat 7 through the slewing support main shaft, and a bearing is also arranged at the matching connection between the slewing support main shaft and the bearing seat 7. The bearing seat 7 is a frame structure that only plays the role of rotating and connecting the slewing shaft, and no further limitation is made here.

[0054] In some feasible embodiments, the overall length of the bearing seat 7 is 270 mm, the width is 250 mm, and a 12 mm thick iron plate is used. The bearing model that can be selected is H4070.

[0055] In the above scheme, the bearing seat 7 provides a stable rotation connection for the slewing arm 2. Through the support and positioning of the bearing seat 7, the slewing arm 2 can smoothly and accurately realize the rotation action, ensuring the stable operation of the equipment. The bearing is arranged at the matching connection between the slewing support main shaft and the bearing seat 7, which can greatly reduce the friction and wear during the rotation process.

[0056] like Figure 1 As shown, in the preferred scheme, the cutter head includes: a main cutter head 4 and a side cutter head 3. Specifically, a side cutter head 3 is respectively arranged on both sides of the lower end of the rotating arm 2 away from the power device; the main cutter head 4 is arranged between a pair of side cutter heads 3, and the pair of side cutter heads 3 are connected through the main cutter head 4, and then the main cutter head 4 and the pair of side cutter heads 3 are connected to form a stable cutter head structure. Specifically, the main cutter head 4 is arranged at one end of a pair of side cutter heads 3 away from the rotating arm 2, that is, close to the lower end of the side cutter head 3.

[0057] In the above scheme, the side cutter head 3 is used to clean the accumulated materials on the side wall of the chute, and the main cutter head 4 not only plays the main role of fixing, but also can clean the accumulated materials in the chute.

[0058] The side cutter head 3 located on one side of the rotating arm 2 is defined as a first side cutter head 31 , and the side cutter head 3 located on the other side of the rotating arm 2 is defined as a second side cutter head 32 , and the first side cutter head 31 and the second side cutter head 32 are symmetrically arranged about the rotating arm 2 .

[0059] In the above scheme, the first side cutter head 31 and the second side cutter head 32 are symmetrically arranged. By driving the rotating arm 2, the first side cutter head 31 and the second side cutter head 32 work simultaneously, and the accumulated materials in the chute located on both sides of the rotating arm 2 can be scraped off at the same time, which significantly improves the processing efficiency.

[0060] like Figure 1 , Figure 6 As shown, in the preferred solution, the first side blade head 31 includes: a bending plate 311 and a fixing plate 312, wherein the bending plate 311 and the fixing plate 312 are an integrally formed structure. Specifically, the bending plate 311 includes: a first connecting plate 3112 and a first side blade plate 3111, the first connecting plate 3112 is fixedly connected to the connecting plate on the lower end surface of the swivel arm 2 by bolts, the first connecting plate 3112 is arranged at an acute angle with the first side blade plate 3111, and extends downward from the bottom of the first side blade plate 3111 to form a fixing plate 312, through which the main blade head 4 can be connected.

[0061] In some feasible embodiments, the first side cutter head 31 is made of an iron plate with an overall length of 330 mm, a width of 200 mm, a height of 689 mm, and a thickness of 10 mm. The angle between the first connecting plate 3112 and the first side cutter plate 3111 is 75°, and a 10 mm iron plate is used to reinforce and fix the first connecting plate 3112 and the first side cutter plate 3111 at the corner where the first connecting plate 3112 and the first side cutter plate 3111 are connected. The iron plate extends downward from the first connecting plate 3112 and multiple iron plates are arranged in parallel. It can be imagined that the size of the side cutter head 3 is not limited to the above size, and can be adaptively adjusted according to the size of the matching components and the size of the chute required for scraping, and no further limitations are made here.

[0062] In the above scheme, the bending plate 311 and the fixed plate 312 are an integrated structure, which ensures the connection strength between the bending plate 311 and the fixed plate 312. The one-piece design reduces the material and processing costs in the production process, and also reduces the cost of replacement due to component damage, thereby improving the structural strength and stability of the entire side cutter head 3; the setting of the fixed plate 312 facilitates the installation of the main cutter head 4; the first connecting plate 3112 is set at an acute angle to the first side cutter plate 3111, which makes it easier for the first side cutter plate 3111 to scrape off the accumulated material on the side wall of the slide pipe.

[0063] Specifically, the first side blade 3111 is arranged parallel to the side wall of the chute. When the side blade head 3 is driven by the rotating arm 2 to make a rotating motion, it can directly act on the accumulated material on the side wall of the chute, and the cleaning effect is good.

Second main cutting heads 42 are also provided at both ends of the first main cutting head 41. The second main cutting heads 42 are evenly spaced circumferentially on the outer wall of the first main cutting head 41, and the ends of the second main cutting heads 42 are connected to the second connecting plate 43. Specifically, four second main cutting heads 42 are evenly spaced circumferentially on the side wall of the first main cutting head 41. The second main cutting heads 42 are similar to a right-angled triangle mechanism. One right-angled side of the second main cutting head 42 of the triangle is fixed on the side wall of the first main cutting head 41, and the other right-angled side is fixedly connected to the second connecting plate 43. The setting of the second main cutting head 42 not only improves the connection strength, but also cooperates with the first main cutting head 41 to realize the scraping of the accumulated material in the chute.

[0065] In some feasible embodiments, the first main cutting head 41 adopts a thick-walled tube with a diameter of 50 mm and a length of 560 mm, and the second connecting plate 43 adopts a 10 mm thick iron plate. The width of the iron plates on both sides is 130 mm and the height is 200 mm. They are fixed to the first connecting plate 3112 on both sides with 20 mm bolts and are detachable to facilitate the replacement of the main cutting head 4 later.

[0066] In the above scheme, the second main cutting head 42 is evenly spaced circumferentially arranged on the outer wall of the first main cutting head 41, which not only enhances the ability to scrape away accumulated materials, but also ensures the uniformity and comprehensiveness of scraping, so that the main cutting head 4 is more efficient in scraping away accumulated materials in the chute and reduces the residual accumulated materials; the setting of the second main cutting head 42 not only improves the connection strength, but also cooperates with the first main cutting head 41 to realize the scraping of accumulated materials in the chute; it is fixedly connected to the first connecting plate 3112 through the second connecting plate 43, so that the main cutting head 4 is fixed to the side cutting head 3 through the second connecting plates 43 on both sides.
