Casting shakeout hopper based on timing forward and reverse rotation control

[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 based on timing forward and reverse control of this embodiment includes a hopper body 1. The lower end of the hopper body 1 is provided with a discharge port 2, and a support sleeve 3 is installed outside the discharge port 2 to support A guide sleeve 4 is installed on the inner side of the 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 a thrust bearing 5, in the ring groove on the upper surface of the inner folding ring 31 Balls 32 are installed; the inner wall of the discharge port 2 is equipped with a support base 6 through multiple support rods 10. The lower surface of the support base 6 is mounted with a motor protection cover 8 and a motor 7 located in the motor protection cover 8. The output of the motor 7 A rotating shaft 9 is installed on the shaft. The side wall of the rotating shaft 9 is connected with a connecting rod 11 up and down. The end of the connecting rod 11 is provided with a mounting sleeve 14. The mounting sleeve 14 abuts against the inner wall of the guide sleeve 4 and contacts the outer wall of the guide sleeve 4 The screw 15 is screwed; the outer wall of the connecting rod 11 is rotated and installed with a stirring shaft 12, the stirring shaft 12 is arranged upward, and the outer wall is spirally connected with the stirring sheet 13; the outer side of the support sleeve 3 is installed with a control box 18, which is installed in the control box 18 There are a timing controller 16 and a forward and reverse controller 17 of the motor 7.

[0012] When the present invention is working, the motor 7 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the guide sleeve 4 to rotate. The guide sleeve 4 agitates the sand in it through the connecting rod 11. At the same time, the agitating shaft 12 and the agitating plate on the connecting rod 11 13 Follow the rotation of the sand material to avoid the sand material from blocking the discharge port 2 and ensure the continuous supply of sand material; the timing controller 16 in the control box 18 sets the time, and the forward and reverse controller 17 regularly controls the forward direction of the motor 7 Rotation and reversal, so as to control the forward and reverse rotation of the guide sleeve 4 and the connecting rod 11, and 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 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.
