Detailed Embodiments

[0031] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, the starch-based material blending and modification equipment in one embodiment of the utility model includes: a bin body 1, a pair of multiple stirring drive mechanisms 2, and multiple groups of self-vibrating stirring blades 3.

[0033] like Figure 1 As shown, one side of the silo body 1 is connected with a feed pipe 101. Materials are added into the silo body 1 through the feed pipe 101.

[0034] like Figure 1 As shown, a discharge pipe 102 is connected to the side of the silo 1 away from the feed pipe 101, and the discharge pipe 102 is higher than the feed pipe 101. The blended and modified materials in the silo 1 are discharged through the discharge pipe 102.

[0035] like Figures 1 to 4 As shown, a pair of multiple stirring drive mechanisms 2 are symmetrically assembled on the upper and lower sides of the bin body 1, and the multiple stirring drive mechanisms 2 include a stirring shaft 201, which is rotatably assembled in the bin body 1. The stirring shaft 201 is used to assemble, limit and rotate multiple groups of self-vibrating stirring blades 3.

[0036] like Figure 1 As shown, the upper and lower sides of the silo 1 are fixedly equipped with stirring motors 205, and the output shaft of the stirring motor 205 is drivingly connected with the stirring shaft 201. The stirring motor 205 plays the role of providing power, and the stirring shaft 201 is driven to rotate by controlling the operation of the stirring motor 205, so as to facilitate driving multiple groups of self-vibrating stirring blades 3 to blend and modify the materials in the silo 1.

[0037] like Figures 5 to 6 As shown, the outer side of the stirring shaft 201 is fixedly connected with a plurality of evenly distributed transmission bevel gears 202. The transmission bevel gears 202 play a role of rotationally driving the driving bevel gear 203.

[0038] like Figures 5 to 6 As shown, both sides of the transmission bevel gear 202 are meshed with driving bevel gears 203. The driving bevel gear 203 plays the role of assembly limit and rotation drive for the transmission shaft 204.

[0039] As Figures 5 to 6 shown, a transmission rotating shaft 204 is fixedly connected inside each of a plurality of driving bevel gears 203. The clamping member 301 is assembled and fixed and rotationally driven through the transmission rotating shaft 204.

[0040] As Figures 3 to 4 shown, a plurality of fitting sleeves 206 are sleeved outside the stirring rotating shaft 201. The plurality of fitting sleeves 206 are sleeved outside a plurality of sets of transmission bevel gears 202, and all the plurality of transmission rotating shafts 204 are rotatably connected to the fitting sleeves 206. The fitting sleeves 206 play a role in assembling and protecting the transmission bevel gears 202 and the driving bevel gears 203. At the same time, the fitting sleeves 206 can be used to limit the assembly of the transmission rotating shafts 204.

[0041] As Figures 3 to 4 shown, linkage top covers 207 are uniformly arranged on both the upper and lower sides of the fitting sleeve 206. The linkage top covers 207 are sleeved outside the stirring rotating shaft 201. The linkage top covers 207 play a role in sealing and protecting the fitting sleeves 206. At the same time, the fitting sleeves 206 can be rotationally driven by the linkage top covers 207 rotating with the stirring rotating shaft 201, so as to drive a pair of transmission rotating shafts 204 to rotate synchronously.

[0042] As Figures 3 to 4 shown, a plurality of uniformly distributed assembly bolts 208 are threadedly connected between the linkage top cover 207 and the fitting sleeve 206. The plurality of assembly bolts 208 play a role in assembling and fixing the linkage top cover 207 and the fitting sleeve 206.

[0043] As Figures 3 to 4 shown, a locking sleeve 209 is integrally formed on one side of the linkage top cover 207 facing away from the fitting sleeve 206. The linkage top cover 207 is assembled and fixed by locking and fixing the locking sleeve 209.

[0044] As Figures 3 to 4 shown, a pair of locking bolts 210 are threadedly connected to the outside of the locking sleeve 209, and the locking bolts 210 are arranged in cooperation with the stirring rotating shaft 201. The locking sleeve 209 is locked and fixed to the outside of the stirring rotating shaft 201 through the pair of locking bolts 210, so that the linkage top cover 207 can drive the fitting sleeve 206 and the transmission rotating shaft 204 to rotate synchronously with the rotation of the stirring rotating shaft 201, so as to perform co - mixing and modification on the materials in the bin body 1.

[0045] As Figures 3 to 4As shown, multiple groups of self-vibrating stirring blades 3 are fixedly assembled on one side of multiple drive rotating shafts 204 away from the driving bevel gear 203. The self-vibrating stirring blade 3 includes a clamping member 301, and one end of the clamping member 301 is fixedly connected to the drive rotating shaft 204. The clamping member 301 plays a role in connecting and fixing the stirring blade 302 and the drive rotating shaft 204, so that the stirring blade 302 can rotate synchronously with the rotation of the drive rotating shaft 204 under the action of the clamping member 301.

[0046] Specifically, the clamping member 301 is arranged in a concave shape. It is convenient to assemble and limit the stirring blade 302 through the clamping member 301.

[0047] As Figures 3 to 4 shown, a number of fixing bolts 304 are fixedly connected between the clamping member 301 and the stirring blade 302. The clamping member 301 and the stirring blade 302 are assembled and fixed through a number of fixing bolts 304.

[0048] As Figures 1 to 2 shown, the other end of the clamping member 301 is snap-fitted with the stirring blade 302. The rotation of the stirring blade 302 can mix and stir the materials in the bin body 1.

[0049] Among them, a pair of vibration diversion grooves are formed in the stirring blade 302. The vibration diversion grooves provide an assembly and operation space for the collision balls 303, the limit reed pieces 305, and the limit springs 306.

[0050] As Figures 1 to 2 shown, a pair of collision balls 303 are evenly arranged in a pair of vibration diversion grooves. The stirring blade 302 can self-vibrate under the collision of the pair of collision balls 303, thereby improving the mixing and stirring effect of the stirring blade 302.

[0051] As Figures 1 to 2 shown, a pair of limit reed pieces 305 are slidably assembled in the vibration diversion grooves, and a pair of collision balls 303 are arranged between the pair of limit reed pieces 305. The limit reed pieces 305 and the limit springs 306 cooperate with each other to limit the vibration of the pair of collision balls 303, reducing the risk of collision wear of the stirring blade 302 and the collision balls 303 caused by the mutual collision of the pair of collision balls 303 and the inner wall of the vibration diversion grooves.

[0052] As Figures 1 to 2 shown, a pair of limit springs 306 are fixedly connected to the sides of the pair of limit reed pieces 305 away from the collision balls 303, and the ends of the limit springs 306 away from the limit reed pieces 305 are fixedly connected to the inner wall of the vibration diversion grooves. The contraction and reset of the limit springs 306 support and limit the limit reed pieces 305. At the same time, the cooperation between the limit reed pieces 305 and the limit springs 306 can play an auxiliary role in the vibration effect of the collision balls 303.

[0053] As Figures 3 to 5 shown, baffles 307 are fixedly connected to both sides of a pair of vibration diversion grooves. The surface of the baffle 307 located outside the vibration diversion groove is on the same horizontal plane as the outer surface of the stirring paddle 302. The baffle 307 plays a role in moving and limiting the collision balls 303. By arranging the baffle 307 and the stirring paddle 302 on the same horizontal plane, the situation of material residue at the assembly position of the stirring paddle 302 and the baffle 307 is reduced.

[0054] During specific use, materials are added into the bin body 1 through the feed pipe 101. By controlling the rotation of the stirring motor 205, the stirring rotating shaft 201 is driven to rotate. When the stirring rotating shaft 201 rotates, the fitting sleeve 206 can drive the transmission rotating shaft 204 to rotate synchronously with the rotation of the stirring rotating shaft 201 under the action of the linkage top cover 207 and the locking bolts 210. By the way that the transmission rotating shaft 204 rotates with the stirring rotating shaft 201, multiple groups of stirring paddles 302 are driven to rotate, so as to mix and stir the materials in the bin body 1.

[0055] Meanwhile, the transmission rotating shaft 204 can rotate self - rotatively under the meshing action of the transmission bevel gear 202 and the driving bevel gear 203. By the self - rotation of the transmission rotating shaft 204, the stirring paddle 302 is driven to rotate self - rotatively, so that multiple groups of stirring paddles 302 can perform multiple stirring on the materials in the bin body 1 under the action of the transmission rotating shaft 204.

[0056] In addition, during the rotation of the stirring paddle 302, a pair of collision balls 303 can collide in the vibration diversion groove. Through the collision of the collision balls 303, the stirring paddle 302 has a self - vibration function. At the same time, the mutual cooperation of the collision balls 303, the limiting reed 305 and the limiting spring 306 can play an auxiliary role in the self - vibration effect of the stirring paddle 302, thereby further improving the effect of the stirring paddle 302 in mixing and stirring the materials, and improving the efficiency and uniformity of the co - blending modification of the starch - based material.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non - restrictive.
