DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] See also Figure 1 The utility model provides a batching device applied to a concrete mixing station, comprising a quantitative lower hopper 1, a frame 2 and an easy-to-clean pipeline structure 3. The frames 2 are installed on both left and right side walls of the quantitative lower hopper 1, and the easy-to-clean pipeline structure 3 is installed at the bottom outlet of the quantitative lower hopper 1.

[0023] See also Figure 2-5The easy-to-clean pipeline structure 3 in the utility model includes an elbow pipeline 31, a support 32, a conveying pipeline 33, a butt joint 34, an annular groove 35, a through groove 36, a handle 37, a No. 1 mounting hole 38, a No. 2 mounting hole 39 and a positioning bolt 310. The elbow pipeline 31 is installed at the bottom outlet of the quantitative lower hopper 1, and the top opening of the elbow pipeline 31 is connected with the bottom outlet of the quantitative lower hopper 1. A support 32 is welded and fixed at the bottom of the elbow pipeline 31. The support 32 is in a long strip shape. The conveying pipeline 33 is hingedly installed at the front end of the support 32. The conveying pipeline 33 is parked on the top surface of the support 32. The support 32 provides bottom support for the conveying pipeline 33. The butt joint 34 is slidably installed on the inner rear end of the conveying pipeline 33. An annular groove 35 is provided at the front of the elbow pipeline 31, and the butt joint 34 can be inserted straight The conveying pipe 33 is fitted into the inner side of the annular groove 35, so that the conveying pipe 33 and the elbow pipe 31 are tightly connected, and the connection is not easy to leak. A through groove 36 is provided in the rear half of the top surface of the conveying pipe 33, and a handle 37 is provided on the top of the conveying pipe 33. The protrusion at the bottom of the handle 37 passes through the through groove 36 and is screwed to the docking pipe 34. The user can control the telescopic movement of the docking pipe 34 through the handle 37. A No. 1 mounting hole 38 and a No. 2 mounting hole 39 are provided on the top surface of the conveying pipe 33, wherein the No. 1 mounting hole 38 is located directly behind the through groove 36, and the No. 2 mounting hole 39 is located directly behind the No. 1 mounting hole 38. A positioning bolt 310 is threadedly connected to the screw hole at the rear end of the handle 37, and the positioning bolt 310 can be screwed into the inner side of the No. 1 mounting hole 38 or the No. 2 mounting hole 39 to lock the position of the docking pipe 34.

[0024] To further explain, a rubber pad 321 is bonded to the top surface of the support 32. The thickness of the rubber pad 321 is at least 5 mm. The rubber pad 321 acts as a buffer between the support 32 and the delivery pipe 33, so that the support 32 and the delivery pipe 33 are not easily rubbed or collided with each other to produce abnormal noise.

[0025] It is further explained that the rotatable angle of the delivery pipe 33 is not less than 180°, so that the delivery pipe 33 has a sufficiently large rotation angle for easy adjustment during cleaning work.

[0026] It is further explained that the telescopic length of the butt joint pipe 34 is not less than 5 cm, ensuring that there is sufficient connection length between the butt joint pipe 34 and the annular groove 35, and the connection is stable and not easy to fall off.

[0027] To further illustrate, when the positioning bolt 310 is inserted into the No. 1 mounting hole 38, the docking tube 34 will be completely retracted into the conveying pipe 33. When the positioning bolt 310 is inserted into the No. 2 mounting hole 39, the docking tube 34 will be able to be completely inserted into the inner side of the annular groove 35, so that the position of the docking tube 34 can be judged more clearly, and the positioning operation is simple and convenient.

[0028] To further illustrate, when the delivery pipe 33 is parked on the top surface of the support 32, the positions of the butt joint 34 and the annular groove 35 correspond to each other, so the positioning is convenient and the plug-in connection can be completed quickly.

[0029] Here’s how it works:

[0030] First, before use, first place the frame 2 on a flat ground to ensure that the quantitative lower hopper 1 is placed stably without shaking, and confirm that the conveying pipe 33 and the elbow pipe 31 remain in a docking state to ensure that the conveying pipe 33 can convey materials normally, and then the batching operation can be started.

[0031] Second, when in use, first add the material into the quantitative discharge hopper 1. The quantitative discharge hopper 1 can control the material to be discharged according to the set amount, so that the materials can be mixed according to the predetermined ratio. By setting an easy-to-clean pipe structure 3 at the bottom outlet of the quantitative discharge hopper 1, the material is discharged from the quantitative discharge hopper 1 and first enters the inside of the elbow pipe 31, and then passes through the butt joint 34 to enter the inside of the conveying pipe 33. At this time, the material can be guided along the conveying pipe 33 and discharged into the mixer for mixing, thereby realizing material transportation.

[0032] Third, after use, some residual materials are easily adhered to the inner wall of the conveying pipe 33. In order to facilitate the cleaning of the conveying pipe 33, the positioning bolt 310 can be unscrewed from the No. 2 mounting hole 39, and then the handle 37 is held and moved to the front end of the through groove 36, and the positioning bolt 310 is screwed into the No. 1 mounting hole 38 to prevent the butt joint 34 from moving freely. In this way, the butt joint 34 is pulled back to the inside of the conveying pipe 33, thereby releasing the connection between the conveying pipe 33 and the elbow pipe 31, and the conveying pipe 33 can be flipped outward from the top of the support 32. At this time, both ends of the conveying pipe 33 are in an open state, which is convenient for the user to clean the inside of the conveying pipe 33. The cleaning is convenient and the cleaning effect is good.

[0033] Fourth, after cleaning, first turn the delivery pipe 33 over and place it on the top of the support 32, then unscrew the positioning bolt 310 from the No. 1 mounting hole 38, then hold the handle 37 and move it to the rear end of the through groove 36, and screw the positioning bolt 310 into the No. 2 mounting hole 39, so as to push the connecting pipe 34 out of the delivery pipe 33, so that the connecting pipe 34 is inserted into the inner side of the annular groove 35, thereby tightly connecting the delivery pipe 33 with the elbow pipe 31, and completing the resetting operation of the delivery pipe 33, which is convenient to operate and has a low learning cost.

[0034] Fifth, by providing a rubber pad 321 on the top surface of the support 32, the rubber pad 321 plays a buffering role between the support 32 and the delivery pipe 33, so that the support 32 and the delivery pipe 33 are not easy to rub and collide with each other to produce abnormal noise.

[0035] The utility model provides a batching device applied to a concrete mixing station, wherein an easy-to-clean pipe structure 3 is arranged at the bottom outlet of a quantitative lower hopper 1, and a positioning bolt 310 is screwed out from the second mounting hole 39, and then the handle 37 is held to move it toward the front end of the through groove 36, and the positioning bolt 310 is screwed into the first mounting hole 38 to prevent the butt joint 34 from moving freely, so that the butt joint 34 is pulled back to the inner side of the conveying pipe 33, thereby releasing the connection between the conveying pipe 33 and the elbow pipe 31, and the conveying pipe 33 can be turned outward from the top of the support 32 to be unfolded, and at this time, both ends of the conveying pipe 33 are in an open state, so that the user can clean the inside of the conveying pipe 33 conveniently, and the cleaning is convenient and effective, and a rubber pad 321 is arranged on the top surface of the support 32, and the rubber pad 321 plays a buffering role between the support 32 and the conveying pipe 33, so that the support 32 and the conveying pipe 33 are not easy to rub and collide with each other to produce abnormal noise.
