[0014] In summary, the present application includes at least one of the following beneficial technical effects:
[0015] 1. Concrete enters the container through the feed port. Because one end of the crank is movably connected to the container, and the other end of the crank is fixedly installed on the first motor, when the device is started, the motor rotates, driving the crank to rotate, so that the container swings back and forth to shake the concrete evenly.

DETAILED DESCRIPTION
[0023] The present application is further described in detail below in conjunction with the accompanying drawings.
[0024] Example, see Figure 1-Figure 4 A concrete screw feeder includes a feed part and a conveying part connected to the feed part, the feed part includes a storage device 2 and a filter device 1 installed in the storage device 2, the filter device 1 includes a first motor 11 and a crank 12 movably connected to the first motor 11, one end of the crank 12 is connected to the first motor 11, and the other end of the crank 12 is connected to a container 13, and the bottom of the container 13 is a filter screen 131. The storage device 2 includes a box body 21, and a feed port 211 and a through hole 212 are opened on the box body 21, and the feed port 211 is directly opposite to the container 13. Concrete enters the container 13 through the feed port 211. Because one end of the crank 12 is movably connected to the container 13 and the other end of the crank 12 is fixedly mounted on the first motor 11, when the device is started, the motor rotates, driving the crank 12 to rotate, so that the container 13 swings back and forth to shake the concrete evenly. Because the bottom of the container 13 is set as a filter 131, the concrete is filtered into the box 21, which effectively prevents larger impurities from entering the conveying part and extends the service life of the device.
[0025] Reference Figure 1 as well as Figure 4A stabilizing frame 213 is fixedly installed in the box body 21, and the container 13 is slidably connected to the stabilizing frame 213. When concrete enters the container 13, the container 13 may be damaged due to the influence of gravity. By fixing the stabilizing frame 213 in the box body 21, because the container 13 is slidably connected to the stabilizing frame 213, the stabilizing frame 213 can buffer the container 13 to prevent damage to the device, thereby effectively improving the service life of the device.
[0026] Reference Figure 1 , Figure 2 as well as Figure 3 The conveying part also includes a supporting device 4 and a transmission device 3 installed on the supporting device 4. The transmission device 3 includes a conveying pipe 31. The conveying pipe 31 is connected to the box body 21 and penetrates the through hole 212. The conveying pipe 31 is provided with a discharge port 311. Two screw rods 32 are installed in the conveying pipe 31. One end of the two screw rods 32 away from the box body 21 is respectively connected with a second motor 33. When concrete enters the box body 21 after being filtered through the container tank 13, by opening the through hole 212 on the box body 21, because the conveying pipe 31 is installed on the box body 21 and penetrates the through hole 212, and two screw rods 32 are installed in the conveying pipe 31, and the two screw rods 32 are respectively fixedly connected with the two second motors 33, the two second motors 33 are started to drive the rotation of the screw rod 32. Because the conveying pipe 31 is provided with a discharge port 311, the screw rod 32 transports the concrete to the discharge port 311. By setting two screw rods 32, the transport amount of the device is increased and the working efficiency is improved.
[0027] Reference Figure 2 as well as Figure 3 The output shafts of the two second motors 33 are connected to fans 333, and the fans 333 are far away from the conveying pipe 31. In the process of transporting concrete from the screw rod 32 to the discharge port 311, concrete may remain on the screw rod 32 or on the inner wall of the conveying pipe 31. Since the fans 333 are fixedly mounted on the second motors 33 and the fans 333 are far away from the conveying pipe 31, when the second motors 33 are started, the fans 333 rotate to supply air into the conveying pipe 31, so that the residue is blown down to the box body 21, which effectively improves the service life of the device.
[0028] Reference Figure 1A telescopic support rod 22 is installed at the bottom of the box 21. Four telescopic support rods 22 are provided and arranged in a rectangular array at the bottom of the box 21. The support device 4 includes two fixed blocks 41 installed on the conveying pipe 31. The two fixed blocks 41 are symmetrically distributed on the sides of the conveying pipe 31. Connecting rods 42 are respectively installed on the two fixed blocks 41. The connecting rods 42 are movably connected to the first telescopic support frame 43. The second motor 33 is fixedly installed on the support plate 331. The second telescopic support frame 332 is installed at the bottom of the support plate 331. When it is necessary to adjust the conveying angle or height of the device, the telescopic support rod 22 is fixedly installed at the bottom of the box body 21, and two fixed blocks 41 are fixedly installed on the side of the conveying pipe 31, and two connecting rods 42 are fixedly connected to the two fixed blocks 41 respectively, and the two connecting rods 42 are movably connected to the first telescopic support frame 43. Because the second motor 33 is fixedly installed on the support plate 331, and the second telescopic support frame 332 is fixedly installed at the bottom of the support plate 331, the height of the device can be adjusted by adjusting the telescopic support rod 22, the first telescopic support frame 43 and the second telescopic support frame 332. Because the connecting rod 42 is movably connected to the first telescopic support frame 43, the transport angle of the device can be adjusted by adjusting the connecting rod 42, which effectively improves the work efficiency of the staff.
[0029] Reference Figure 1 A connecting buckle 214 is fixedly installed on the box body 21. When the device needs to be used at a high place, it is not easy for the staff to carry it because the device is too heavy. Since the connecting buckle 214 is fixedly installed on the box body 21, the connecting buckle 214 can be connected to other equipment to transport the device to a high place.
[0030] Working principle:
[0031] 1. When the device is in use, concrete enters the container 13 through the feed port 211, the motor rotates, driving the crank 12 to rotate, so that the container 13 swings back and forth to shake the concrete evenly, and the filter screen 131 at the bottom of the container 13 filters the concrete into the box body 21. The rotation of the second motor 33 rotates the screw rod 32 and the fan 333, and the screw rod 32 transports the concrete from the box body 21 to the conveying pipe 31. The concrete is transported outside the device through the discharge port 311, which prevents impurities from remaining in the conveying pipe and effectively improves the service life of the device.
[0032] 2. When the conveying angle or height of the device needs to be adjusted, the height of the device can be adjusted by adjusting the telescopic support rod 22, the first telescopic support frame 43 and the second telescopic support frame 332. By adjusting the connecting rod 42, the conveying angle of the device can be adjusted, which effectively improves the work efficiency of the staff.
[0033] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
