Description

Technical Field

[0001] The utility model relates to the field of scraping devices, in particular to a scraping mechanism. Background Art

[0002] In the construction of water conservancy projects, water is mostly transported through canals. Over a long period of time, a large amount of silt is easily deposited on the inner wall of the canal, which not only affects the appearance but may also affect the normal operation of the canal.

[0003] The existing canal silt scraping technology is generally divided into two types: manual and automatic. The manual operation is: manually holding a scraper and continuously scraping along the inner wall of the canal to scrape off the silt, which is time-consuming, labor-intensive, and inefficient. The automatic silt scraping refers to fixing two scrapers on both sides of a movable body. As the body moves, the scrapers can move synchronously to scrape off the silt on the inner wall of the canal. However, since the width and inclination angle of each segment of the canal are not fixed, when the body drives the scraper to move, if the inner cavity of the canal is narrow, the body cannot drive the scraper to continue moving. If the inner cavity of the canal is wide, the scraper cannot contact the inner wall of the canal, which will also cause the scraper to be unable to scrape off the silt. At the same time, if the inner wall of the canal is in an inclined state, one end of the scraper can contact the inner wall of the canal, but the other side cannot contact it, which ultimately causes the scraper to be unable to scrape off all the silt, thereby affecting the overall cleaning effect.

[0004] Therefore, it is necessary to invent a scraping mechanism. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a scraping mechanism, comprising a body and an empty slot, the middle of the body is provided with an empty slot, adjustment components are symmetrically installed on both sides of the inner cavity of the empty slot, a scraper is installed on one side of the adjustment component, a water storage tank is installed at the rear end of the inner cavity of the empty slot, a conveying component is installed on the upper end of the water storage tank, guide pipes are symmetrically arranged on both sides of one end of the conveying component, and a nozzle is installed on the other side of the guide pipe.

[0007] Based on the above features: when the machine body moves in the canal, the adjustment component can adjust the position and inclination angle of the scrapers on both sides of the machine body, so that the scrapers can fit the inner wall of the canal. When the machine body moves, the scrapers can clean the silt adhered to the inner wall of the canal. If some silt is adsorbed for a long time and condensed and difficult to clean, the conveying component can extract water from the water tank, and then spray it to both sides through the guide pipe and the nozzle, so that the silt on the inner wall of the canal can be sprayed with water to moisten it before the scraper scrapes the silt, so that the scraper can quickly scrape off the silt and improve work efficiency. When scraping is not required, the adjustment component can fold and put away the scraper, so that the scraper can be stored inside the empty groove. It will not only not take up too much space, but also avoid the scraper being exposed outside when the machine body is moved out of the canal, causing accidental injury to the operator.

[0008] Preferably, moving wheels are installed on the bottom of the body, and a supporting seat and a limiting frame are installed on the outer wall of the body.

[0009] Based on the above features: the machine body can be moved by the moving wheels, the support seat can limit the end of the conveying component away from the water tank, and the set limit frame can also limit the conveying component to avoid tilting and deviation during long-term installation and use.

[0010] Preferably, the adjustment assembly includes a first connecting plate and a second connecting plate, wherein a connecting shaft is connected between the first connecting plate and the second connecting plate toward an adjacent side, a bearing seat is installed at the upper end of the connecting shaft, and a gear is installed at the bottom end of the connecting shaft.

[0011] Based on the above characteristics: when the two gears rotate in opposite directions, the gears can drive the first connecting plate and the second connecting plate to swing in opposite directions through the connecting shaft. When the first connecting plate and the second connecting plate swing backwards, the first connecting plate and the second connecting plate will drive the scrapers to move synchronously. At this time, the distance between the two scrapers will become smaller, which is convenient for cleaning the inner wall of the narrower canal. When the scraper swings forward and is in a horizontal state, the distance between the two scrapers will become larger, which is convenient for cleaning the inner wall of the wider canal. When the scraper needs to be stored, the first connecting plate and the second connecting plate can drive the scraper to rotate backwards and be stored on both sides of the inner cavity of the empty groove.

[0012] Preferably, telescopic cylinders are symmetrically mounted on both ends of one side of the first connecting plate and the second connecting plate away from the connecting shaft, and a knife seat is mounted on the other side of the telescopic cylinder.

[0013] Based on the above characteristics: when the width of the canal is large, the telescopic cylinder can drive the knife holder and the scraper to move and adjust the overall length. At the same time, if the inner wall of the canal is inclined, the upper and lower telescopic cylinders can be extended and retracted one by one according to the inclination of the inner wall of the canal. At this time, the knife holder and the scraper will be tilted, making it convenient for the scraper to scrape silt from the inclined inner wall of the canal.

[0014] Preferably, a slot is provided on a side of the knife holder away from the telescopic cylinder, and positioning convex plates are symmetrically installed at both ends of the side of the knife holder away from the slot.

[0015] Based on the above features: the scraper is inserted into the slot on one side of the blade holder, and after the scraper is inserted, it can be locked and fixed by using screws.

[0016] Preferably, the maximum swing angle of the first connecting plate and the second connecting plate is less than 180 degrees.

[0017] Based on the above features: the first connecting plate and the second connecting plate can conveniently drive the scraper to unfold and contact the inner wall of the channel, and at the same time can drive the scraper to fold back and be stored on both sides of the inner cavity of the empty groove.

[0018] Preferably, the conveying assembly includes a suction pump and a drainage pipe and a water distribution pipe connected to the output end of the suction pump, the water distribution pipe is located at one end of the drainage pipe away from the suction pump, and the guide pipes are symmetrically arranged at intervals on both sides of the water distribution pipe.

[0019] Based on the above characteristics: the suction pump can extract the water from the water tank, then introduce it into the guide pipe through the guide pipe and the water distribution pipe, and finally spray it to both sides through the nozzle.

[0020] The beneficial effects of the utility model are:

[0021] 1. It is convenient to clean the inner side walls of water channels of different widths. When the first connecting plate and the second connecting plate swing backward, the first connecting plate and the second connecting plate will drive the scrapers to move synchronously. At this time, the distance between the two scrapers will become smaller, which is convenient for cleaning the inner side walls of narrow water channels. When the scrapers swing forward and are in a horizontal state, the distance between the two scrapers will become larger, which is convenient for cleaning the inner side walls of wider water channels. When the scrapers need to be stored, the first connecting plate and the second connecting plate can drive the scrapers to rotate backward and store them on both sides of the inner cavity of the empty groove.

[0022] 2. It is convenient to clean the inner wall of the inclined canal. If the inner wall of the canal is inclined, the upper and lower telescopic cylinders can be extended and retracted one at a time according to the inclination of the inner wall of the canal. At this time, the knife seat and the scraper will be inclined, which is convenient for the scraper to scrape the silt from the inclined inner wall of the canal. At the same time, when the two telescopic cylinders are extended and adjusted at the same time, the spacing between the two scrapers can also be driven to improve the overall adjustability.

[0023] 3. Improve work efficiency. If some silt is adsorbed for a long time and condensed, it is difficult to clean. The suction pump can extract the water from the water tank, and then introduce it into the guide pipe through the guide pipe and the water distribution pipe, and finally spray it to both sides through the nozzle. In this way, the silt on the inner wall of the canal can be sprayed with water to moisten it before the scraper scrapes the silt, making it easier for the scraper to quickly scrape off the silt.

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] See attached Figure 1-4 The utility model provides a scraping mechanism, including a body 1 and an empty slot 2, the middle of the body 1 is provided with an empty slot 2, adjusting components 3 are symmetrically installed on both sides of the inner cavity of the empty slot 2, a scraper 4 is installed on one side of the adjusting component 3, a water storage tank 5 is installed at the rear end of the inner cavity of the empty slot 2, a conveying component 6 is installed on the upper end of the water storage tank 5, guide pipes 7 are symmetrically arranged on both sides of one end of the conveying component 6, and a nozzle 8 is installed on the other side of the guide pipe 7.

[0031] When the machine body 1 moves in the canal, the adjustment component 3 can adjust the position and inclination angle of the scrapers 4 on both sides of the machine body 1, so that the scrapers 4 can fit the inner wall of the canal. When the machine body 1 moves, the scrapers 4 can clean the sludge adhered to the inner wall of the canal. If some sludge is adsorbed for a long time and condensed and difficult to clean, the conveying component 6 can extract water from the water tank 5, and then spray it to both sides through the guide pipe 7 and the nozzle 8, so that the sludge on the inner wall of the canal can be sprayed with water to moisten it before the scraper 4 scrapes the sludge, so that the scraper 4 can quickly scrape off the sludge and improve work efficiency. When no scraping operation is required, the adjustment component 3 can fold and put away the scraper 4, so that the scraper 4 can be stored inside the empty groove 2. It will not only not take up too much space, but also avoid the scraper 4 being exposed outside when the machine body 1 is moved out of the canal, causing accidental injury to the operator.

[0032] Furthermore, a moving wheel 11 is installed at the bottom of the body 1 , and a supporting seat 12 and a limiting frame 13 are installed on the outer wall of the body 1 .

[0033] The body 1 can be moved by the moving wheel 11, the support seat 12 can limit the end of the conveying component 6 away from the water tank 5, and the set limit frame 13 can also limit the conveying component 6 to avoid tilting and deviation of the conveying component 6 during long-term installation and use.

[0034] Furthermore, the adjustment assembly 3 includes a first connecting plate 31 and a second connecting plate 32 , and a connecting shaft 33 is connected between the first connecting plate 31 and the second connecting plate 32 toward the middle of the adjacent side, a bearing seat 34 is installed at the upper end of the connecting shaft 33 , and a gear 35 is installed at the bottom end of the connecting shaft 33 .

[0035] The gears 35 are arranged in two mutually meshing states, and a motor is arranged at the lower end of one of the gears 35 to drive the two gears 35 to rotate in opposite directions (the motor is arranged at the bottom end of the inner cavity of the machine body 1, which is not drawn in the figure for special explanation). When the two gears 35 rotate in opposite directions, the gears 35 can drive the first connecting plate 31 and the second connecting plate 32 to swing in opposite directions through the connecting shaft 33. When the first connecting plate 31 and the second connecting plate 32 swing backward, the first connecting plate 31 and the second connecting plate 32 will drive the scraper 4 to move synchronously. At this time, the distance between the two scrapers 4 will become smaller, which is convenient for cleaning the inner wall of the narrower canal. When the scraper 4 swings forward and is in a horizontal state, the distance between the two scrapers 4 will become larger, which is convenient for cleaning the inner wall of the wider canal. When the scraper 4 needs to be stored, the first connecting plate 31 and the second connecting plate 32 can drive the scraper 4 to rotate backward and be stored on both sides of the inner cavity of the empty slot 2.

[0036] Furthermore, telescopic cylinders 311 are symmetrically mounted on both ends of one side of the first connecting plate 31 and the second connecting plate 32 away from the connecting shaft 33 , and a knife seat 312 is mounted on the other side of the telescopic cylinder 311 .

[0037] The first connecting plate 31 and the second connecting plate 32 are connected and fixed to the scraper 4 through the knife holder 312, and when the width of the canal is large, the telescopic cylinder 311 can drive the knife holder 312 and the scraper 4 to move and adjust the overall length. At the same time, if the inner wall of the canal is inclined, the upper and lower telescopic cylinders 311 can be extended and retracted one by one according to the inclination of the inner wall of the canal. At this time, the knife holder 312 and the scraper 4 will be inclined, making it convenient for the scraper 4 to scrape silt from the inclined inner wall of the canal.

[0038] Furthermore, a slot 3121 is provided on a side of the knife holder 312 away from the telescopic cylinder 311 , and positioning convex plates 3122 are symmetrically installed at both ends of the side of the knife holder 312 away from the slot 3121 .

[0039] The scraper 4 is inserted into the slot 3121 on one side of the knife seat 312. After the scraper 4 is inserted, it can be locked and fixed with screws. The upper and lower ends of one side of the knife seat 312 are movably hinged with the piston end of the telescopic cylinder 311 through the positioning convex plate 3122, which facilitates the telescopic cylinder 311 to move and adjust the inclination angle of the knife seat 312 and the scraper 4.

[0040] Furthermore, the maximum swing angle of the first connecting plate 31 and the second connecting plate 32 is less than 180 degrees.

[0041] The first connecting plate 31 and the second connecting plate 32 can drive the scraper 4 to unfold and contact the inner wall of the channel, and can also drive the scraper 4 to fold back and be stored on both sides of the inner cavity of the empty slot 2.

[0042] Furthermore, the conveying assembly 6 includes a suction pump 61 and a drainage pipe 62 and a water distribution pipe 63 connected to the output end of the suction pump 61. The water distribution pipe 63 is located at one end of the drainage pipe 62 away from the suction pump 61, and the guide pipe 7 is symmetrically arranged on both sides of the water distribution pipe 63 in an interval shape.

[0043] The suction pump 61 can extract the water from the water tank 5, and then introduce it into the guide pipe 7 through the guide pipe 7 and the water distribution pipe 63, and finally spray it to both sides through the nozzle 8. The set limit frame 13 can limit the outside of the water distribution pipe 63, and the support seat 12 can limit and support the bottom of the water distribution pipe 63.

[0044] The use process of the utility model is as follows: when the body 1 moves in the canal through the moving wheel 11, the motor can drive the gear 35 to rotate in opposite directions. At this time, the two gears 35 can drive the first connecting plate 31 and the second connecting plate 32 to swing in opposite directions through the connecting shaft 33. When the first connecting plate 31 and the second connecting plate 32 swing backward, the first connecting plate 31 and the second connecting plate 32 will drive the scraper 4 to move synchronously. At this time, the distance between the two scrapers 4 will become smaller, and when the scraper 4 swings forward to be in a horizontal state, the distance between the two scrapers 4 will become larger. When the scraper 4 needs to be stored, the first connecting plate 31 and the second connecting plate 32 can drive the scraper 4 to rotate backward and be stored on both sides of the inner cavity of the empty groove 2. At the same time, if the inner side wall of the canal is inclined, the upper and lower telescopic cylinders 311 can be extended and retracted one by one according to the inclination of the inner side wall of the canal. At this time, the knife seat 312 and the scraper 4 will be tilted, so that the scraper 4 fits on the inclined inner side wall of the canal.
