The arc-shaped water bed is installed on the traction platform. The bottom part of the drum of the drum screen is located in the arc-shaped water bed. The arc-shaped water bed gradually approaches the drum along the sand discharge direction. The grate plate is installed in the arc-shaped water bed and is located below the drum. A sewage cavity is formed between the arc-shaped water bed and the grate plate. At least one scraper is installed on the outer peripheral surface of the drum obliquely along the curved surface direction of the drum.

[0006] A further technical solution is: one end of the arc-shaped water bed is rotatably connected to the traction platform, and the other end of the arc-shaped water bed is elastically connected to the traction platform via a spring.

[0007] A further technical solution is that rubber bristles are planted on the outer peripheral surface of the drum.

[0008] A further technical solution is: a material storage bin adapted to the screw conveyor is installed on the traction platform.

[0009] A further technical solution is: a sandbag conveyor matched with the hopper is installed on the traction platform.

[0010] A further technical solution is: a bag sewing machine matching the sandbag conveyor is installed on the traction platform.

[0011] A further technical solution is: a top plate is arranged above the traction platform, a hopper connected to the feed end of the drum screen is installed on the top plate, the hopper is composed of a plurality of bin plates rotatably connected to the top plate, and the bin plates are connected by bolts.

[0012] A further technical solution is that a traction head is rotatably mounted on at least one side of the traction platform.

[0013] A further technical solution is that hydraulic supports are installed around the traction platform.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: The present invention proposes a trailer-type flood control sandbag packaging machine. The packaging machine has a simplified structure, has screening and quantitative filling functions, and is easy to drag.

[0028] Embodiment 1: In this embodiment, Figure 1 As shown, a trailer-type flood control sandbag packaging machine includes a traction platform 1, a drum screen 2, a belt conveyor 3, a screw conveyor 4, a hopper scale 5 and a sand washing bed 6 installed on the traction platform 1; wherein, The screen residue outlet of the drum screen 2 is located above the feed end of the sand washing bed 6; The discharge end of the sand washing bed 6 is located above the upper belt surface of the belt conveyor 3; The discharging end of the belt conveyor 3 is connected to the feeding end of the screw conveyor 4; The discharge end of the screw conveyor 4 is connected to the feed end of the hopper scale 5; The sand washing bed 6 includes an arc-shaped water bed 7, a grate plate 8 with water filtering holes and a scraper 9. The arc-shaped water bed 7 is installed on the traction platform 1. The bottom part of the drum 13 of the drum screen 2 is located in the arc-shaped water bed 7. The arc-shaped water bed 7 gradually approaches the drum 13 along the sand discharge direction. The grate plate 8 is installed in the arc-shaped water bed 7 and is located below the drum 13. A sewage cavity 10 is formed between the arc-shaped water bed 7 and the grate plate 8. At least one scraper 9 is installed on the outer peripheral surface of the drum 13 obliquely along the curved surface direction of the drum 13.

[0029] The sand and gravel on site are put into the feed port of the drum screen 2 by a forklift, and the drum screen 2 starts to work. The screen residue falls into the arc water bed 7 of the sand washing bed 6. The water in the arc water bed 7 is used to separate the mud and sand. The cleaned sand and gravel remain on the grate plate 8. As the drum 13 rotates, the cleaned sand and gravel are scraped out along the inner wall of the arc water bed 7 by the scraper 9 (which can be a rubber scraper), and fall on the belt conveyor 3. They are sent to the feed port of the screw conveyor 4 through the belt conveyor 3. The screw conveyor 4 transports the sand and gravel of suitable particle size to the hopper scale 5. According to the weight requirement of the flood control sandbag, the material is automatically discharged into the empty sandbag to complete the filling. When the operation of a flood control point is completed or the situation changes and it is necessary to transfer the operation, because of its light weight, it can be towed by a car to complete the traction. The packaging machine has a simplified structure, has screening and quantitative filling functions, and is easy to drag. First, it reduces the cost of the equipment, and second, it retains basic functions to reduce the weight of the equipment. During on-site emergency flood control operations, it can be easily moved and sited at any time as the situation changes, improves on-site adaptability, and facilitates on-site scheduling and transportation during the journey. The packaging machine can also wash the sand of appropriate particle size screened out from the drum screen to reduce the soil content in the sand and gravel. During flood control, it prevents the sandbags from shrinking due to the impact of water flow and carrying away the soil, which affects the use of sandbags for flood control.

[0030] Preferably, one end of the arc-shaped water bed 7 is rotatably connected to the traction platform 1 , and the other end of the arc-shaped water bed 7 is elastically connected to the traction platform 1 via a spring 11 .

[0031] When too much screen residue from the drum screen 2 falls on the arc water bed 7, under the action of the spring 11, the arc water bed 7 moves downward to temporarily accommodate more material to prevent blockage between the arc water bed 7 and the drum screen 2. The spring 11 can also provide elastic force at all times, so that the arc water bed 7 maintains a certain distance upward from the drum screen 2, which can ensure that the cleaned sand and gravel are scraped out along the inner wall of the arc water bed 7 by the scraper 9; it can also improve the scrubbing effect of the drum screen 2 and the scraper 9 on the mud and sand, and improve the separation effect of sand and gravel from soil.

[0032] In addition, one end of the arc-shaped water bed 7 is rotatably connected to the traction platform 1, and the end of the arc-shaped water bed 7 is at a certain distance from the drum screen 2, so as to ensure that the cleaned sand and gravel are scraped out by the scraper 9, and the discharge is stable.

[0033] At least one scraper 9 is installed on the outer circumference of the drum 13 at an angle along the curved surface of the drum 13. When sand and gravel fall on the arc water bed 7 and move downward along the inclined direction, the scraper 9 of this shape can push the material on the arc water bed 7 from the tail to the head and turn it out, ensuring that the sand and gravel that fall on the arc water bed 7 subsequently has sufficient sand washing stroke and accommodation space.

[0034] Preferably, the outer circumferential surface of the roller 13 is planted with rubber bristles 12 .

[0035] When the drum 13 rotates, the rubber bristles 12 can improve the cleaning effect on the sand and gravel.

[0036] Preferably, a material storage bin 14 adapted to the screw conveyor 4 is installed on the traction platform 1 .

[0037] The storage bin 14 can be used to temporarily store the screen residue of the drum screen 2. During on-site operation, if the mud or large-grained stones in the sand and gravel are large, it is necessary to stop the machine for cleaning or replace the drum. The storage bin 14 plays a buffering role and does not cause the sandbag filling to stop. At the same time, when the working speed of the drum screen 2 and the sandbag filling speed do not match, the fault tolerance of both is improved.

[0038] Preferably, a sandbag conveyor 15 adapted to the hopper scale 5 is installed on the traction platform 1. A bag sewing machine 16 matched with the sandbag conveyor 15 is installed on the traction platform 1.

[0039] The sandbag conveyor 15 is used to convey the filled sandbags, and the packing personnel do not need to move the sandbags extra, which reduces the working pressure. The sandbags on the sandbag conveyor 15 are moved to the bag sewing machine 16 and are sewn.

[0040] Embodiment 2: Based on the above embodiment, this embodiment shows that a top plate 17 is arranged above the traction platform 1, and a hopper 18 connected to the feed end of the drum screen 2 is installed on the top plate 17. The hopper 18 is composed of a plurality of bin plates rotatably connected to the top plate 6, and the bin plates are connected by bolts.

[0041] The bin plates can be erected and connected to each other by bolts to form a hopper 18 for temporarily storing external sand and gravel materials. Usually, they can be placed flat on the top plate 17 to reduce the height of the packaging machine. When transporting on the way, it can ensure that the packaging machine can pass through the height-restricted road.

[0042] A further technical solution is that a traction head 19 is rotatably mounted on at least one side of the traction platform 1 .

[0043] The traction head 19 is rotatably connected to the side of the traction platform 1 through a rotating shaft, which is convenient for connection with a power source when towing.

[0044] Preferably, hydraulic supports 20 are installed around the traction platform 1 .

[0045] The hydraulic support 20 is connected to the hydraulic system of the packaging machine and is extended during operation to form a stable support with the ground to ensure the safe and stable operation of the packaging machine.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
