In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.

It should be noted that, in the drawings, both the chain feeding direction and the chain discharging direction of the chain 400 are moving directions relative to the first sprocket 210, the chain feeding direction is from bottom to top (shown by a left arrow in fig. 2), the chain discharging direction is from top to bottom (shown by a right arrow in fig. 2), the vertical direction is an up-down direction, and the horizontal plane is a left-right direction.

Referring to fig. 1 to 3, a scraper conveyor head according to an embodiment of the present invention includes a frame 100, a chain 400, a driving device 500, a first wheel set 200, a second wheel set 300, and a blanking portion 600. A first wheel set 200 driven by the driving device 500, including a first sprocket 210, the first wheel set 200 being disposed on the upper side of the frame 100; the second wheel set 300 is located below the first wheel set 200, and is offset towards one side relative to the position right below the first wheel set 200, and the second wheel set 300 comprises a second chain wheel 310; the chain 400 is meshed with the second chain wheel 310, a scraper (not shown) is connected to the chain 400, the chain 400 is meshed with the second chain wheel 310 and the first chain wheel 210 in sequence, and the chain 400 on the side of the chain entering is close to the chain 400 on the side of the chain exiting through the second wheel set 300; the blanking portion 600 is located below the second wheel set 300.

Because the second wheel set 300 is deviated relative to the first wheel set 200, the chain 400 on one side of the feeding direction is close to the chain 400 on one side of the discharging direction when passing through the second wheel set 300, so that the chain 400 and the horizontal plane can form a certain angle, which is beneficial for the dried sludge to fall into the discharging part 600 from the scraper, and is convenient for thorough discharging.

The first wheel set 200 includes a first sprocket 210 and a first rotation shaft 220, the first sprocket 210 is nested on the first rotation shaft 220, and the driving device 500 is connected to the first rotation shaft 220 and drives the first rotation shaft 220 to rotate, thereby driving the first sprocket 210 to rotate. Similarly, the second wheel set 300 includes a second sprocket 310 and a second rotation shaft 320. The chain 400 may have two chains with a plurality of scrapers, and correspondingly, the first wheel set 200 has two first sprockets 210 respectively fitted on two ends of the first rotating shaft 220, and the second wheel set 300 includes two second sprockets 310 respectively fitted on two ends of the second rotating shaft 320, and the chains 400 are engaged with the first sprockets 210 and the second sprockets 310. Since the second wheel set 300 is offset towards the left side relative to the right side of the first wheel set 200, after the chain 400 enters the rack 100, the chain 400 passes through the right side of the second chain wheel 310, and the second chain wheel 310 jacks up the chain 400 in the up-down direction, so that the scraper inclines and forms a certain included angle with the horizontal plane. Therefore, when the chain 400 moves to the right side of the second sprocket 310, the scrapers incline, sludge adhered to the scrapers and located between the adjacent scrapers can fall into the blanking portion 600 under the action of gravity, complete blanking is realized, and the blanked chain 400 carries the scrapers to continue to pass through the first sprocket 210 and move below the frame 100. It should be noted that the offset angle between the second wheel set 300 and the first wheel set 200 may be 5 degrees to 15 degrees, that is, the angle between the line connecting the axes of the first rotating shaft 220 and the second rotating shaft 320 and the vertical direction is 5 degrees to 15 degrees. The smaller the offset angle, the larger the inclination angle of the scraper when the chain 400 bypasses the second sprocket 310, thereby more facilitating the sludge to fall onto the blanking portion 600.

In addition, the blanking portion 600 may be a blanking plate 610 integrally formed with the frame 100 and located below the second sprocket 310. The blanking plate 610 is disposed at an angle with respect to the horizontal plane, which is greater than 45 degrees, so that the rack 100 as a whole presents an inverted "Y" shape. Those skilled in the art can set the angle between the blanking plate 610 and the horizontal plane as long as the dried sludge is guaranteed to slide into the delivery vehicle through the blanking plate 610.

Referring to fig. 3, in some embodiments, in order to facilitate the disassembly of the rack 100, the rack 100 may include a first sub-rack 110, a second sub-rack 120, and a third sub-rack 130, when the rack 100 is assembled, the first sub-rack 110 may be detachably connected to the upper side of the second sub-rack 120, the third sub-rack 130 may be detachably connected to the lower side of the second sub-rack 120, a blocking plate 140 may be further installed at openings at the left and right sides of the first sub-rack 110, the second sub-rack 120, and the third sub-rack 130, and a cover plate 150 may be installed at the top of the first sub-rack 110, thereby forming a completely closed rack 100. The first wheel set 200 is mounted to the first sub-frame 110, and in particular, the first wheel set 200 may be mounted between the first sub-frame 110 and the second sub-frame 120, and the second wheel set 300 is mounted to the second sub-frame 120, and in particular, the second wheel set 300 may be mounted between the second sub-frame 120 and the third sub-frame 130. The blanking portion 600 is located at the third sub-frame 130, and specifically, the blanking plate 610 may be integrally formed with the third sub-frame 130, or the blanking plate 610 may be welded to the third sub-frame 130. The rack 100 formed by the combination mode is more convenient to disassemble, and when the interior of the rack 100 needs to be cleaned and maintained, the first sub-rack 110, the second sub-rack 120 and the third sub-rack 130 can be disassembled to be cleaned or maintained respectively. In addition, the lower plate 610 and the third sub-frame 130 are integrally formed, which is simpler than the case where the lower plate 610 and the frame 100 are integrally formed. The connection among the first sub-frame 110, the second sub-frame 120 and the third sub-frame 130 may be a screw coupling.

Referring to fig. 2, in some embodiments, for stable movement of the chain 400, the face conveyor head further includes a guide 700, the guide 700 being capable of guiding the chain 400. The guide part 700 includes a first guide groove 710, the first guide groove 710 is coupled to the frame 100, for example, the first sub frame 110, and the first guide groove 710 is located at one side, for example, the right side, in the axial direction of the first sprocket 210. The first guide groove 710 supports the left side of the chain 400 so that the chain 400 can stably move supported by the first guide groove 710 and pass through the first wheel set 200 after entering the frame 100. In some embodiments, the first guide channel 710 is screwed to the frame 100, so that the first guide channel 710 is easy to detach. Due to the second sprocket 310, the chain 400 reduces pressure and friction against the first guide groove 710 during movement, preventing the first guide groove 710 from being worn.

With continued reference to fig. 2, in some embodiments, in order to keep the chain 400 stably moving after redirection, the guide portion 700 further includes a second guide slot 720, and the second guide slot 720 is connected to the frame 100 and is located at one side, for example, the right side, in the axial direction of the second sprocket 310. The second guide groove 720 guides the chain 400 as the chain 400 passes through the second sprocket 310 to stabilize the chain 400 passing through the second wheel set 300, preventing the flight from being severely shaken or shifted during the movement. In some embodiments, the upper end of the second guiding groove 720 can be bent toward the second sprocket 310, for example, toward the left side, so as to better guide the chain 400 to change direction through the second sprocket 310, and to smoothly transition and avoid the chain 400 from being jammed during the moving process. In order to make the head structure of the scraper conveyor compact, the blanking portion 600, i.e., the blanking plate 610, may be welded to the second guide groove 720.

Referring to fig. 4, in some embodiments, the scraper conveyor head further comprises a sweeping device 800, the sweeping device 800 being connected to the first wheel set 200, e.g., to the first rotational shaft 220. The cleaning device 800 includes a fixing member 810 capable of being sleeved or clamped on the first rotating shaft 220, and a plurality of cleaning members 820 arranged at intervals outside the fixing member 810, wherein the plurality of cleaning members 820 are perpendicular to the chain 400. When the chain 400 winds the first chain wheel 210, the cleaning piece 820 is perpendicular to the chain 400, the cleaning piece 820 collides with the scraper, and in the collision process, the cleaning piece 820 and the scraper rub against each other, so that dried sludge which is small in volume and small in adhesion force and adheres to the scraper is scraped off, and the effect of cleaning the scraper is achieved. The cleaning element 820 may be in the shape of a sheet or a plate perpendicular to the chain 400, or may be in the shape of a frame with a hollow center, as long as sludge on the blade can be scraped off. The cleaning member 820 may be elastic in that it does not damage the blade after the blade collides. In some embodiments, the number of the cleaning members 820 is equal to the number of teeth of the first sprocket 210, and this design ensures that the cleaning members 820 can collide with each scraper to completely remove a small amount of sludge on the scraper as much as possible.
