Anti-blocking efficient shakeout hopper for dry-sand full mold casting

[0010] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, the sand falling hopper for casting production of this embodiment includes a hopper body 1. The lower end of the hopper body 1 is provided with a discharge port 2. A support sleeve 3 is installed outside the discharge port 2, and a support sleeve 3 is installed inside the support sleeve 3 The guide sleeve 4 is rotatably installed between the lower end of the discharge port 2 and the inner folding ring 31 of the support sleeve 3 through the thrust bearing 5, and the ball 32 is installed in the ring groove on the upper surface of the inner folding ring 31; The outer wall of the material sleeve 4 is provided with a driven gear ring 6, the side of the support sleeve 3 is equipped with an external drive motor 8 through a bracket 7, and a driving gear 9 meshing with the driven gear ring 6 is installed on the drive shaft of the external drive motor 8; A supporting seat 11 is installed in the guide sleeve 4 through a plurality of supporting rods 10, an agitating shaft 12 is installed on the upper side of the supporting seat 11, a rotating agitating sheet 13 is installed on the agitating shaft 12, and the lower side of the supporting seat 11 is installed The inner driving motor 14 connected with the stirring shaft 12, the inner driving motor 14 is installed with a motor protection cover 15; the driving directions of the inner driving motor 14 and the outer driving motor 8 are opposite; the outer wall of the supporting sleeve 3 is installed with a control box 18 to control A timing controller 17 electrically connected to each other and a forward and reverse controller 16 of the outer drive motor 8 and the inner drive motor 14 are installed in the box 18.

[0012] When the present invention is working, the motor 8 drives the driving gear 9, the driving gear 9 drives the driven gear ring 6, the driven gear ring 6 drives the guide sleeve 4 to rotate, and the stirring shaft 12 and the stirring blade 13 in the guide sleeve 4 rotate to achieve Stir the sand to avoid blocking the discharge port 2; the timing controller 15 sets the time, and the forward and reverse rotation of the motor 8 is controlled by the forward and reverse controller 14, and the forward and reverse rotation of the stirring shaft 12 and the stirring piece 13 , To further ensure that the discharge port 2 is not blocked.

[0013] The above-mentioned embodiments are the preferred embodiments of the present invention. They are only used to facilitate the description of the present invention, and are not intended to limit the present invention in any form. Anyone with ordinary knowledge in the technical field, if they do not deviate from the provisions of the present invention Within the scope of the technical features, the equivalent embodiments with partial changes or modifications made by using the technical content disclosed in the present invention without departing from the technical features of the present invention still fall within the scope of the technical features of the present invention.
