[0040] Example 1

[0041] like Figures 1-9 As shown, this utility model provides a sand distribution bin 1, with a top opening and at least two discharge ports 11 on opposite sides of the bottom of the sand distribution bin 1. A bag hanging mechanism 4 is provided on each discharge port 11, allowing sandbags 7 to be hung under or removed from the discharge ports 11 via the bag hanging mechanism 4. A rotating shaft 5 is rotatably mounted in the center of the sand distribution bin 1, with a rotating drive 52 connected to the top of the shaft 5. Switching valve plates 53 are connected to opposite sides of the bottom of the shaft 5, and the contour surface of the switching valve plate 53 can cover at least one discharge port 11. A sand conveyor 2 is located on one side of the sand distribution bin 1 and connected to the top opening side of the sand distribution bin 1. A sandbag conveyor 3 is located on one side of the sand distribution bin 1 and connected to the bottom side of the sand distribution bin 1.

[0042] Specifically, the upper part of the sand distribution bin 1 is funnel-shaped, and the lower inner side is a cylindrical channel. Four discharge ports 11 are spaced at equal angles in the lower part of the sand distribution bin 1, two on each side, and the centers of these discharge ports 11 are concentric circles. A rotating shaft 5 is vertically positioned in the center of the sand distribution bin 1. The bottom end of the rotating shaft 5 is embedded in the bottom wall of the sand distribution bin 1 and connected to a bearing. This area is sealed by a bearing housing and other structures to prevent sand and gravel from entering and damaging the bearing.

[0043] The bottom of the rotating shaft 5 is symmetrically fixed with two switch valve plates 53. The end of the switch valve plate 53 is in an enlarged structure, which can completely cover and block the material outlet 11 to stop the material falling. There are two symmetric switch valve plates 53 on the rotating shaft 5, so that two material outlets 11 at diagonal positions can be blocked at the same time. Two operators can be arranged on the two sides of the sand distribution bin 1 respectively, and two operators can simultaneously fill bags, so that two sandbags 7 can be filled in one switching cycle, thereby improving the filling efficiency. Each operator is responsible for two material outlets 11 during the operation. In each operation, one of the material outlets 11 is blocked by the switch valve plate 53, and the other material outlet 11 is open for bagging operation. When the sandbag 7 under the open material outlet 11 is filled, the operator operates the rotating driver 52 to start, and the rotating shaft 5 rotates 90 degrees to control the rotating position of the switch valve plate 53, so that the originally blocked material outlet 11 is open, and the originally open material outlet 11 is blocked, thereby realizing non-stop bag changing.

[0044] During the bagging process, the operator hangs the sandbag 7 under each material outlet 11 through the bag hanging mechanism 4. During the operation of one material outlet 11, the sandbag 7 under the other material outlet 11 is waiting for use. When the sandbag 7 under the originally open material outlet 11 is filled, the operator switches the switch valve plate 53, and the originally open material outlet 11 is blocked. The operator can take the sandbag 7 from the bag hanging mechanism 4 for binding, and since the material outlet 11 is blocked at this time, there will be no sand and stone leakage. During the process of binding the filled sandbag 7, the originally blocked material outlet 11 is opened, and another sandbag 7 is hung under the material outlet 11 through the bag hanging mechanism 4, so that the sand and stone will fall into the sandbag 7 (during the initial stage of bagging, since the sand and stone in the bag is not much, the weight of the sandbag 7 is not high, and the bag hanging mechanism 4 will not be pulled off by the weight). When the operator binds the filled sandbag 7 and throws it into the sandbag conveyor 3, a new empty sandbag 7 is hung on the empty bag hanging mechanism 4, and the sandbag 7 being filled is operated (at this time, the sand in the sandbag 7 increases, and the weight increases, but the operator has already manually filled the sandbag 7, so the bag hanging mechanism 4 will not be pulled off by the weight).

[0045] The sand and stone conveyor 2 can adopt a conveying belt device in the prior art. The excavated sand and stone is sent to the sand and stone conveyor 2, and then falls into the sand distribution bin 1 through the top opening of the sand distribution bin 1. The sandbag conveyor 3 can adopt a conveying belt device in the prior art. The filled and bound sandbag 7 is thrown into the sandbag conveyor 3 and sent to the transfer area.

[0046] Embodiment 2

[0047] The top of the sand distribution bin 1 is rotatably provided with a worm 54, which is in transmission connection with the rotary driver 52. The rotating shaft 5 is provided with a worm wheel 51, which is in engagement with the worm 54. The opposite sides of the sand distribution bin 1 are respectively provided with switching buttons 56, which are in signal connection with the rotary driver 52. The outer side of the rotating shaft 5 is connected with a spiral plate 55.

[0048] Specifically, the rotating shaft 5 is driven to rotate through the worm wheel and worm structure. The two ends of the worm 54 penetrate through the opposite sides of the top of the sand distribution bin 1, and bearings are arranged to assist rotation. A motor or a motor and a belt pulley device can be arranged on the outer side of the top of the sand distribution bin 1, and are in transmission connection with the extending end of the worm 54. The worm wheel 51 is fixedly connected to the top end of the rotating shaft 5, and is in engagement with the threaded part on the worm 54. The motor drives the rotating shaft 5 to rotate through the worm 54 and the worm wheel 51, so as to realize the rotation switching of the switching valve plate 53. An equipment bin (not shown) is arranged on the upper part of the sand distribution bin 1. The rotating shaft 5 penetrates and inserts into the equipment bin. The worm 54 and the worm wheel 51 on the top of the rotating shaft 5 are located in the equipment bin, so as to avoid damage to the worm wheel and worm device caused by the sand and stone materials.

[0049] In addition, the two sides of the sand distribution bin 1 are respectively provided with switching buttons 56. The switching buttons 56 are arranged at positions which are easy to be pressed by operators. When both of the switching buttons 56 are pressed, the motor is started to rotate. When only one of the switching buttons 56 is pressed, or none of the switching buttons 56 is pressed, the motor is not started. In this way, when one operator finishes bagging and the other operator does not finish bagging, the switching valve plate 53 will not be switched.

[0050] Through the spiral plate 55 on the outer side of the rotating shaft 5, the spiral plate 55 is rotated to stir the sand and stone materials in the sand distribution bin 1, so as to make the sand and stone materials flow smoothly when the rotating shaft 5 rotates each time.

[0051] Example 3

[0052] As Figure 4 and Figure 8As shown, the bag hanging mechanism 4 comprises a falling pipe 41 connected below the falling opening 11 and a hook 42 connected to the falling pipe 41. The bag opening 71 of the sandbag 7 is wrapped outside the outlet of the falling pipe 41, and the drawstring 72 of the sandbag 7 is hung on the hook 42. The falling pipe 41 comprises an inclined pipe section 411 connected obliquely below the falling opening 11 and a straight pipe section 412 connected vertically at the bottom of the inclined pipe section 411. The bottom outlet of the straight pipe section 412 is provided with an outwardly extending hanging ring 413, and the bag opening 71 of the sandbag 7 is wrapped outside the hanging ring 413. One end of the hook 42 is rotatably connected to one side of the inclined pipe section 411, and the other end of the hook 42 is provided with two hook bodies 421. The hook 42 and the inclined pipe section 411 are provided with an elastic support 43. The elastic support 43 comprises an outer shell 431 and a telescopic column 432. The outer shell 431 is connected to the inclined pipe section 411, and a spring 433 is arranged in the outer shell 431. One end of the telescopic column 432 is slidably inserted into the outer shell 431 and abuts against the spring 433, and the other end of the telescopic column 432 extends out of the outer shell 431 and abuts against or rotatably connects to the hook 42.

[0053] Specifically, the bag opening 71 of the sandbag 7 is in the structure of the drawstring 72, and the bag opening 71 is closed by pulling out the drawstring 72. Such a sandbag 7 with a drawstring opening is a prior art, and the principle thereof will not be described in detail. The hanging ring 413 is a ring of outer edges extending outwardly from the outlet of the falling pipe 41. The bag opening 71 is sleeved outside the hanging ring 413, and the drawstring 72 is hung between the two hook bodies 421 of the hook 42 by pulling out the drawstring 72. Since the bag opening 71 is reduced by pulling out the drawstring 72, the bag opening 71 of the sandbag 7 is hung on the hanging ring 413 and cannot be detached.

[0054] The end of the hook 42 is rotatably connected to one side of the inclined pipe section 411 and is outwardly supported by the elastic support 43, thereby providing an outward supporting force by the elastic support 43. When the sandbag 7 is hung, the drawstring 72 hung between the two hook bodies 421 is kept in the pulled-out state, and the bag opening 71 of the sandbag 7 is hung on the hanging ring 413 and cannot be detached. When the sandbag 7 needs to be removed, the operator pinches the hook 42 to compress the elastic support 43 and release the drawstring 72.

[0055] The elastic support 43 provides an elastic force by the spring 433, and the end of the telescopic column 432 located in the outer shell 431 is in an enlarged structure and is limited by a hole in the outer shell 431 for sliding of the telescopic column 432, thereby preventing the telescopic column 432 from coming out of the outer shell 431. One connection mode is that the end of the outer shell 431 is rotatably connected to the falling pipe 41, and the end of the telescopic column 432 is rotatably connected to the hook 42. Another connection mode is that the end of the outer shell 431 is fixedly connected to the falling pipe 41, and the end of the telescopic column 432 abuts against but is not connected to the hook 42.

[0056] Embodiment 4

[0057] The bottom of the sand distribution bin 1 is provided with a groove plate 6, and the sand bag 7 is erected on the groove plate 6.

[0058] Specifically, when the sand bag 7 is filled, the top bag opening 71 is hung by the bag hanging mechanism 4, and the bottom bag bottom is placed on the groove plate 6 to support the sand bag 7, so that the operator does not need to hold the sand bag 7 for filling, and the sand bag 7 will not be separated from the bag hanging mechanism 4 due to the increase in weight during the filling process. When the filling is completed and tied, the operator directly pushes the sand bag 7 to the direction of the chute 64, and the sand bag 7 slides along the chute 64 to the sand bag conveyor 3.

[0059] The working mode of the utility model is as follows:

[0060] The sand is conveyed to the sand distribution bin 1 by the sand conveyor 2, and then directly sent to the transportation area by the sand bag conveyor 3 after being filled in the sand distribution bin 1, so that more flood prevention sand bags 7 can be obtained faster, and the ability to respond to flood prevention rescue is improved. During the sand filling process, two operators can operate on both sides of the sand distribution bin 1 at the same time, two sand bags 7 can be filled at a time, and the filling efficiency is improved; the rotation of the switch valve plate 53 is controlled by the motor, the worm 54, the worm gear 51 and the shaft 5, so that one of the two sand distribution bin 1 side discharge ports 11 is blocked, and the other discharge port 11 is opened. After the filling of the opened discharge port 11 is completed, the switch valve plate 53 is switched to block the discharge port 11, and the other discharge port 11 is opened. When the operator ties the filled sand bag 7, the sand falls from the other discharge port 11 into the sand bag 7 hung by the bag hanging mechanism 4, without missing, so that the filling operation can be carried out without stopping and without missing the sand when changing the bag, the filling efficiency is further improved, and the ability to respond to flood prevention rescue is improved.

[0061] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the utility model, but not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
