As shown in fig. 1-7, the automatic small-material feeding device for dry-mixed mortar equipment of this embodiment includes a mixer 10, a feeding pipe 21 disposed at an upper end of the mixer 10, a magnetic attraction device disposed at an upper side of an inlet end of the feeding pipe 21, a feeding device, and a driving device for driving the feeding device to ascend and descend; the feeding device comprises a feeding box 35, a feeding pipe 31 arranged at the lower end of the feeding box 35, and a first baffle 32 arranged at the end part of the outlet end of the feeding pipe 31; the upper side of the first baffle 32 is hinged with the upper side of the inner wall of the charging pipe 31, the magnetic attraction device is used for attracting the first baffle 32, and the inlet end of the charging pipe 21 is matched with the outlet end of the charging pipe 31. Specifically, through placing the powder in the feed box 35, then use drive arrangement to promote the feed box 35 to the blendor 10 upper end, when the feed box 35 moved to the top or suitable position, the feed tube 31 lower extreme was connected with pan feeding pipe 21 upper end, and formed closed pipeline, magnetic means attracts first baffle 32 lower extreme this moment, makes its lower extreme rotatory around the upper end, and pastes in pan feeding pipe 21 inner wall upper end, and then opens the feed tube 31 lower extreme, make the material in the feed box 35 enter into blendor 10 through feed tube 31 and pan feeding pipe 21, carry out the material mixing. The device can be additionally provided with a new feeding device on the basis of not damaging the original structure of the mixer 10 as much as possible, and is particularly suitable for powder which needs accurate control of dosage but has small dosage. Wherein, the feeding pipe 21 and the feeding pipe 31 are made of hard plastic materials or metal materials which can not be attracted by the magnet. The first baffle 32 is made of a metal material capable of being attracted by the magnet. Preferably, the cross-sections of the feeding pipe 21 and the feeding pipe 31 are both square, so that the normal rotation of the first baffle 32 can be facilitated. Preferably, a magnet can be arranged on the lower side of the outlet end of the feeding pipe 31, the first baffle 32 is attracted by the magnet, the overflow of the material is avoided, and the attraction of the magnet to the first baffle 32 is far less than that of the electromagnet 24 to the first baffle 32.

In this embodiment, one end of the feeding pipe 21 far away from the mixer 10 is higher than the other end; the end of the feeding pipe 21 far away from the mixer 10 is a downward inclined notch, and the end of the feeding pipe 31 far away from the feeding box 35 is an upward inclined notch. The entry end of pan feeding pipe 21 and the exit end of filling tube 31 all are equipped with sealed specific, and the area of contact between pan feeding pipe 21 and the filling tube 31 is bigger like this, aims at more easily to sealed the pad also can reduce the risk that the material revealed from the kneck.

Wherein a magnet may be provided at the lower side of the end of the feeding tube 21, by which the second baffle is better attracted, but the attraction of the electromagnet 24 to the second current duty is significantly greater than the attraction of the magnet to it. When the electromagnet 24 is activated, the first baffle 32 and the second baffle are simultaneously attracted, so that the feeding pipe 21 is conducted with the feeding pipe 31.

The holding tank 23 is arranged on the upper side of the inner wall of the end, away from the mixer 10, of the feeding pipe 21 in the embodiment, and the holding tank 23 is used for holding a second baffle. Specifically, because first baffle 32 and second baffle all can enter into pan feeding pipe 21, consequently set up an holding tank 23 that is used for holding the second baffle in pan feeding pipe 21, can reduce blockking of first baffle 32 and second baffle to pan feeding pipe 21 inner space effectively, improve pan feeding pipe 21's available sectional area.

The lower end of the charging box 35 in the embodiment is provided with a charging hopper 34; the outlet end of the hopper 34 is in fluid communication with the feed tube 31. In particular, the hopper 34 enables the entire powder in the hopper 35 to enter the feed duct 31 and thus the mixer 10.

The driving device in this embodiment includes a pair of vertically disposed screws 41, a motor 40 for driving the screws 41 to rotate, and sleeves 36 disposed on two opposite sides of the outer wall of the charging box 35; the sleeve 36 is internally threaded, and the sleeve 36 is threadedly coupled to a threaded rod 41. Specifically, the motor 40 drives the pair of screws 41 to rotate, so that the sleeve 36 moves up and down along the length direction of the screws 41, and the feeding device is pushed to move up and down.

The driving device in this embodiment further comprises a first bracket 43 arranged at the upper end of the mixer 10, and a second bracket 42 arranged on the side wall of the lower end of the mixer 10; the first bracket 43 is rotatably connected to the upper ends of the pair of screws 41, and the second bracket 42 is rotatably connected to the lower ends of the pair of screws 41. Specifically, the bracket is configured to support the screw 41 so that the screw 41 can be stably rotated.

In summary, the small-sized automatic feeding device for dry-mixed mortar equipment of the embodiment is used for placing powder in the feeding box 35, and then using the driving device to lift the feeding box 35 to the upper end of the mixer 10, when the feeding box 35 moves to the uppermost end or a suitable position, the lower end of the feeding pipe 31 is connected with the upper end of the feeding pipe 21, and a closed pipeline is formed, at this time, the magnetic device attracts the lower end of the first baffle 32, so that the lower end of the first baffle rotates around the upper end, and the lower end of the first baffle is attached to the upper end of the inner wall of the feeding pipe 21, and then the lower end of the feeding pipe 31 is opened, so that the material in the feeding box 35 enters the mixer 10 through the feeding pipe 31 and the feeding pipe 21, and the material mixing is performed. The device can be additionally provided with a new feeding device on the basis of not damaging the original structure of the mixer 10 as much as possible, and is particularly suitable for powder which needs accurate control of dosage but has small dosage.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art.
