[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0026] The present application will be further described below in combination with the embodiments.

[0027] Embodiment: a strong mixer integrated wear-resistant bottom scraper holder, referring to the attached Figure 1 -attached Figure 4 , including scraper holder 1, one side of the scraper holder 1 is provided with groove body 11, the side of the scraper holder 1 is provided with a plurality of vertical grooves 13, the groove body 11 is fixed with deflection rod 12, the outer side of the deflection rod 12 is sleeved with knife plate 2, the bottom end of the knife plate 2 is fixed in the groove body 11 through adjusting assembly 3, one side of the bottom end of the knife plate 2 is provided with rotating groove 21, the adjusting assembly 3 includes screw rod 31 fixed to the back of the knife plate 2, spring 32 sleeved on the outer side of the screw rod 31 and nut 33 fixed to the end of the screw rod 31;

[0028] The groove body 11 and the knife plate 2 are both arc-shaped structures; in the device, the adjusting assembly 3 structure can drive the knife plate 2 to rotate around the deflection rod 12 by adjusting the position of the nut 33 on the screw rod 31, adjust the included angle between the knife plate 2 and the scraper holder 1, and compress the spring 32 to achieve the buffering effect when in use, the vertical groove 13 structure on the scraper holder 1 can facilitate the deflection of the screw rod 31 in the vertical groove 13, and the nut 33 is fixed on the outer side of the vertical groove 13 to realize the fixing function.

[0029] The two ends of the spring 32 are fixed to the back of the blade plate 2 and the front of the groove body 11 respectively, and the nut 33 is arranged outside the bottom end of the scraper frame 1; a plurality of groups of vertical grooves 13 and adjusting assemblies 3 are arranged at equal intervals; the blade plate 2 is sleeved outside the deflection rod 12 through the rotating groove 21; the outer surface of the blade plate 2 is stacked with a plurality of layers of wear-resistant alloy materials such as tungsten carbide and cobalt-based alloy. These wear-resistant coatings have high hardness and good wear resistance, can provide reliable wear-resistant protection for the scraper frame 1, and can be locally repaired and re-welded according to the wear condition; through the structure of the scraper frame 1 provided with the groove body 11, the user can adjust the angle of the blade plate 2 in the groove body 11 through the adjusting assembly 3, optimize the angle of the scraper on the scraper frame 1 according to the working principle of the intensive mixer and the characteristics of the material, and make the acting force between the scraper and the material more reasonable, reduce the direct friction and impact between the scraper and the material, reduce the wear degree, improve the wear resistance of the scraper frame 1, and cooperate with the plurality of layers of wear-resistant alloy materials stacked outside the blade plate 2 to improve the use strength and prolong the use time.

[0030] For high-viscosity materials, the scraper angle can be appropriately smaller, such as 30°-45°, so that the scraper can more smoothly cut into the material and reduce the impact caused by material adhesion. If the material has low viscosity and good flowability, the scraper angle can be larger, and 45°-60° is more appropriate, so that the flowability of the material can be utilized to make the scraper easier to push the material and reduce the impact; when the material hardness is relatively high, to avoid the scraper and the material directly colliding and generating a large impact, the scraper angle is preferably about 45°, so that the scraper contacts the material at a certain inclination angle to disperse the impact force. If the material hardness is relatively low, the angle can be appropriately increased to 50°-60° to improve the scraping efficiency and also reduce the impact caused by too small angle and too deep scraping of the material. For materials with large particles, the scraper angle should be smaller, such as 30°-40°, to reduce the direct impact force of the scraper on the particles and prevent the particles from being excessively extruded or scraped, thereby generating additional impact force and wear. For materials with small particle size, the angle can be selected between 40°-60° to effectively scrape the material without generating excessive impact due to the angle.

[0031] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced equivalently; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
