[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] In the present invention, “first” and “second” do not represent specific quantities and orders, but are merely used to distinguish names.

[0034] like Figure 1 and Figure 2 As shown, a scraper structure in one embodiment of the utility model includes a blade body 1 and a connecting portion 2 arranged on the blade body 1; the blade body 1 is provided with a storage space 11 and an adjusting unit 12, the storage space 11 is used to store slurry; the adjusting unit 12 includes an adjusting block 121 arranged in the storage space 11, the adjusting block 121 is adapted to the storage space 11, and the adjusting unit 12 adjusts the capacity of the storage space 11 by moving the position of the adjusting block 121.

[0035] The scraper structure described above changes the capacity of the storage space 11 in the blade body 1 by setting a storage space 11 on the blade body 1 and adjusting the capacity of the storage space 11 by moving the position of the adjustment block 121 in the adjustment unit 12, thereby changing the capacity of the storage space 11 in the blade body 1, so that the scraper can adapt to different usage scenarios.

[0036] In one embodiment, the adjustment unit 12 includes an adjustment slot 122 provided on the blade body 1 and an adjustment connector 123 passing through the adjustment slot 122; one end of the adjustment connector 123 is connected to the adjustment block 121, and the other end protrudes from the adjustment slot 122. Thus, by moving the adjustment connector 123, the adjustment block 121 in the material storage space 11 is driven to move, thereby changing the capacity of the material storage space 11 in the blade body 1 to adapt to different usage scenarios of the scraper.

[0037] In one embodiment, the adjusting block 121 is adapted to the width of the material storage space 11, the adjusting connector 123 is a fixing screw, and a threaded hole adapted to the fixing screw is provided on the adjusting block 121. Thus, the fixing screw is used as the adjusting connector 123, which is convenient for reducing production costs.

[0038] In one embodiment, a feeding hole 13 communicating with the material storage space 11 is provided on the upper portion of the blade body 1, and an adjustment slot 122 is provided on the upper surface of the blade body 1. In this way, it is convenient for the user to add slurry into the material storage space 11, and it is convenient to move the adjustment connector 123 to adjust the adjustment block 121.

[0039] In one embodiment, the blade body 1 includes two adjustment units 12 respectively arranged on both sides of the feeding hole 13, and the two adjustment units 12 are symmetrically arranged relative to the feeding hole 13. In this way, two adjustment units 12 are symmetrically arranged on both sides of the feeding hole 13, and the size of the material storage space 11 is adjusted by adjusting the adjustment connecting members 123 on both sides, thereby expanding the adjustable range of the material storage space 11, and further expanding the use range of the scraper.

[0040] like Figure 3 and Figure 4As shown, in one embodiment, the blade body 1 includes a blade upper part 3 and a blade lower part 4, the blade upper part 3 is provided with a placement groove 31 with an opening facing downward, and the blade lower part 4 is provided with a fitting groove 41 adapted to the placement groove 31; the fitting groove 41 fits onto the placement groove 31 to form a material storage space 11. In this way, through the detachable connection between the blade upper part 3 and the blade lower part 4, the user can replace different blade lower parts 4 according to different pulping speeds to adapt to different scraper pulping ports, thereby expanding the use range of the scraper.

[0041] In one embodiment, the connection part 2 is a connection arm arranged on both sides of the upper part 3 of the blade body. Specifically, the connection arm is an L-shaped arm, and a connection hole is provided at the top of the L-shaped arm. In this way, the L-shaped arm has a high structural strength and can achieve a stable installation effect through the clamping connection and the concentric connection of the connection hole.

[0042] In one embodiment, the fitting groove 41 of the blade lower part 4 is provided with a guide slope, and the guide slope is used to guide the blade upper part 3 to fit onto the blade lower part 4; the angle range of the guide slope is 0.5° to 3°. In this way, the guide slope facilitates the fitting of the blade upper part 3 onto the blade lower part 4, thereby improving the installation efficiency.

[0043] In one embodiment, the lower surface of the blade lower part 4 is provided with an ejection threaded hole 42, and the placement groove 31 of the blade upper part 3 is provided with an ejection flat edge 32 adapted to the ejection threaded hole 42. In this way, by screwing a screw or a threaded pin into the ejection threaded hole 42, and using the end surface of the screw or the threaded pin to push the ejection flat edge 32, the blade lower part 4 is gradually moved away from the blade upper part 3, so as to achieve the purpose of easy disassembly.

[0044] In one embodiment, the ejection threaded holes 42 are at least two threaded holes respectively disposed on both sides of the lower surface of the cutter body lower portion 4. Specifically, the two threaded holes are disposed diagonally. In this way, it is convenient to eject both sides of the cutter body lower portion 4 at the same time, and avoid the sleeve groove 41 and the placement groove 31 from colliding and being damaged.

[0045] In one embodiment, the blade lower part 4 is provided with a blade 43 and a slurry outlet 44 disposed on the blade 43, and the slurry outlet 44 is connected to the storage space 11. In this way, the user can replace different blade lower parts 4 according to different slurry discharge speeds to adapt to different slurry outlets 44, thereby expanding the use range of the scraper.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it 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.
