DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0024] Combination Figure 1 A powder removing device for machine-made sand comprises a powder removing box 1, a feed pipe 2 is fixedly connected to the upper end of the powder removing box 1, the feed pipe 2 is fixedly connected to two groups, a box door 3 is hinged on one side of the powder removing box 1, a material storage drawer 9 is slidably connected inside the powder removing box 1, and a limiting part 6 for limiting the isolation stone powder structure is fixedly connected to the upper end of the material storage drawer 9.

[0025] The utility model is further described below in conjunction with embodiments.

[0026] Embodiment 1:

[0027] See also Figure 1 , Figure 3 and Figure 5 The limiting part 6 includes a mounting block 62 fixedly connected to the upper end of the material storage drawer 9, a mounting groove 63 is provided on the upper surface of the mounting block 62, a locking rod 61 is snap-connected inside the mounting groove 63, a locking block 64 is movably connected to the upper end of the locking rod 61, a limiting plate 65 is hingedly connected to the inner wall of the powder desorption box 1, a motor 4 is fixedly connected to the inner wall of the powder desorption box 1, a rotating rod 41 is fixedly connected to the output end of the motor 4, a screening net 42 is movably connected to one side of the rotating rod 41, a sliding opening 12 is provided on one side of the powder desorption box 1, and the locking rod 61 is slidably connected to the powder desorption box 1 through the sliding opening 12.

[0028] Specifically, the machine-made sand enters the powder removal box 1 from the feed pipe 2, and the hinged limit plate 65 is pulled upward, and then the locking rod 61 and the block 64 are locked in the installation groove 63. At this time, the limit plate 65 is blocked by the block 64 and has a certain inclination angle. The operation of the motor 4 drives the rotating rod 41 to rotate, so that the screening net 42 is tilted, and then the motor 4 stops running, so that the machine-made sand on the screening net 42 slides down along the inclination angle. During the powder removal and screening, the limit plate 65 can guide the stone powder to slide down so that it does not fall into the storage drawer 9. When the stone powder needs to collect the machine-made sand, the locking rod 61 can be pulled out of the installation groove 63 through the sliding port 12, so that the block 64 moves downward, and the limit plate 65 moves downward and is parallel to the inner wall of the powder removal box 1. After the stone powder is screened, the screening structure tilts, so that the machine-made sand slides into the storage drawer 9.

[0029] Embodiment 2:

[0030] See also Figure 1-Figure 4 A feeding port 13 and a movable port 14 are provided at the upper end of the powder desorption box 1, a sliding groove 11 is provided on one side of the powder desorption box 1, and a material storage drawer 9 is slidably connected to the powder desorption box 1 through the sliding groove 11, a mounting plate 10 is fixedly connected to the inner wall of the powder desorption box 1, a spring 101 is fixedly connected to the upper end of the mounting plate 10, and the spring 101 is fixedly connected to the screening net 42, a telescopic rod 7 is fixedly connected to the inner wall of the powder desorption box 1, a vibration motor 72 is fixedly connected to one side of the telescopic rod 7, an inclined plate 71 is fixedly connected to one side of the vibration motor 72, and two groups of inclined plates 71 are fixedly connected, a stopper 5 is movably connected inside the movable port 14, a recovery box 8 is fixedly connected to the inside of the powder desorption box 1, and two groups of recovery boxes 8 are fixedly connected.

[0031] Specifically, the tilting spring 101 of the screening net 42 is stretched at this time, and the generated elastic force provides a stretching force, thereby reducing the situation where the rotating rod 41 is easily damaged due to uneven force caused by the tilting. The telescopic rod 7 is extended so that the vibration motor 72 can contact the screening net 42. The vibration motor 72 runs to vibrate the screening net 42, thereby achieving the powder removal effect. The inclined plate 71 can guide the stone powder dropped by the screening to slide into the recovery box 8. The block 5 contacts the screening net 42, which can prevent the machine-made sand from falling on the contact point between the block 5 and the screening net 42, so that the powder cannot be removed due to the contact between the bottom of the screening net 42 and the vibration motor 72. When unloading the machine-made sand, the block 5 is pulled out, so that when the screening net 42 is tilted, all the machine-made sand on the upper end can slide off.
