Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically to a concrete processing and conveying device. Background Technology

[0002] Concrete refers to cement concrete, which is made by mixing cement as a binder, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. During concrete processing, various raw materials need to be transported to designated locations. Currently, most concrete is mixed directly using a mixer, which results in a longer mixing time.

[0003] Patent application number 201921344081.1 discloses a concrete processing and conveying device. In this device, cement and sand are poured into two spaces inside a box separated by a partition. Then, the seal at the bottom of the box is opened, and the sand and cement are pre-mixed using the conveying auger, cavity, and water holes in the mixing and conveying structure. However, the mixing is only achieved through the mixing and conveying structure during the conveying process, resulting in poor uniformity of the sand and cement mixture. Furthermore, the installation position of the existing box is fixed, requiring workers to drag the water pipe around it when cleaning the box, which is quite troublesome. Also, due to the small opening at the bottom of the box, it is difficult to quickly and thoroughly pour out the impurities after cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a concrete processing and conveying device to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete processing and conveying device, comprising:

[0006] Two support frames are arranged vertically and parallel to each other;

[0007] The box has openings at the top and bottom. The box is rotatably mounted between two support frames via a rotating structure. A mixing and conveying assembly is provided at the bottom of the box. A partition is fixed inside the box, which divides the interior of the box into a first raw material chamber and a second raw material chamber.

[0008] The partition plate has a first through hole and a second through hole distributed vertically. The first raw material chamber is provided with at least two first guide plates, the lower end of which extends into the first through hole. The second raw material chamber is provided with at least two second guide plates, the lower end of which extends into the second through hole. The first guide plates and the second guide plates are staggered, and the upper surface of both the first guide plates and the second guide plates is provided with a guide groove.

[0009] Preferably, each of the support frames includes:

[0010] A support plate, wherein two vertical strips are fixed parallel to each other on the upper end face of the support plate, and a lifting groove is formed between the two vertical strips and the support plate;

[0011] A movable mounting plate, wherein the movable mounting plate is disposed within a lifting groove;

[0012] A lifting structure is provided, which is connected to a movable mounting plate and is used to drive the movable mounting plate to move up and down.

[0013] Preferably, the rotating structure includes a first motor and a connecting rod. The first motor is mounted on the outer wall of one of the movable mounting plates, and the connecting rod is connected between the output end of the first motor and the outer wall of the housing. The other movable mounting plate is connected to the outer wall of the housing via a bearing.

[0014] Preferably, the lifting structure includes:

[0015] An electric telescopic rod is installed at the bottom of the lifting groove, and the top end of the electric telescopic rod is connected to the bottom end of the movable mounting plate.

[0016] A chute, wherein the chute is formed on one side opposite to the two vertical bars;

[0017] A slide bar is fixed to the side of the movable mounting plate and slides in a groove.

[0018] Preferably, the mixing and conveying assembly includes a conveying cylinder, a second motor, and a conveying auger. The second motor is installed at one end of the conveying cylinder, the conveying auger is disposed inside the conveying cylinder, and one end of the conveying auger is connected to the output end of the second motor.

[0019] Preferably, the bottom end of the box is integrally formed with a feeding hopper, and the upper end face of the conveying cylinder and directly below the feeding hopper is provided with a receiving hopper.

[0020] Preferably, the inner diameter of the receiving hopper is not less than the outer diameter of the bottom end of the discharge hopper.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] This invention, by setting a first through hole, a second through hole, and an inclined first and second guide plate with a guide trough, allows some of the cement and sand to fall directly through the gaps into the receiving hopper when cement and sand are added. The remaining cement slides down through the guide trough on the first guide plate and enters the second raw material chamber through the first through hole to mix with the sand. Simultaneously, the remaining sand slides down through the guide trough on the second guide plate and enters the first raw material chamber through the second through hole to mix with the cement. This allows for preliminary mixing before being conveyed by the mixing and conveying assembly, improving the uniformity of subsequent mixing.

[0023] When cleaning the tank, the movable mounting plate can be moved up using an electric telescopic rod, so that the bottom of the hopper moves out of the receiving hopper. Then, the output end of the first motor can drive the tank to rotate, which can effectively improve the cleaning efficiency. There is no need for staff to drag the water pipe around, making cleaning more convenient. When emptying impurities, the tank can be turned so that the upper port with the larger opening faces down, which facilitates the emptying of impurities from inside the tank as well as from the first and second guide plates.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] Figure 1 and Figure 2 These are all schematic diagrams of the overall structure of this utility model. As shown in the figure, the concrete processing and conveying device includes a support frame and a box 1. Two support frames are arranged vertically in parallel. The upper and lower ends of the box 1 are open, and the box 1 is rotatably disposed between the two support frames through a rotating structure. The box 1 can rotate so that during cleaning, the upper end with the larger opening can be turned downwards to facilitate the pouring out of cleaning impurities. A mixing and conveying assembly is provided below the box 1.

[0034] Among them, combined Figure 5 The mixing and conveying assembly includes a conveying cylinder 2, a second motor 10, and a conveying auger 17. The second motor 10 is installed at one end of the conveying cylinder 2, and the conveying auger 17 is located inside the conveying cylinder 2, with one end of the conveying auger 17 connected to the output end of the second motor 10.

[0035] The bottom of the box body 1 is integrally formed with a feeding hopper 19. The upper end of the conveying cylinder 2 and directly below the feeding hopper 19 is provided with a receiving hopper 20. The inner diameter of the receiving hopper 20 is not less than the outer diameter of the bottom of the feeding hopper 19, so that the bottom of the feeding hopper 19 can be inserted into the receiving hopper 20 when feeding.

[0036] See Figure 3 As shown, a partition 9 is fixed inside the box 1, dividing the interior of the box 1 into a first raw material chamber and a second raw material chamber. The first raw material chamber and the second raw material chamber can respectively pour cement and sand. A first through hole 12 and a second through hole 13 are provided on the partition 9, which are distributed vertically. At least two first guide plates 14 are inclinedly arranged in the first raw material chamber, and the lower end of the first guide plate 14 extends into the first through hole 12. At least two second guide plates 18 are inclinedly arranged in the second raw material chamber, and the lower end of the second guide plate 18 extends into the second through hole 13. The first guide plates 14 and the second guide plates 18 are staggered, and a guide groove 15 is provided on the upper surface of both the first guide plates 14 and the second guide plates 18.

[0037] As described above, during use, cement and sand can be simultaneously added to the first and second raw material chambers inside the housing 1. As the cement and sand descend, some of them fall directly through the gaps into the receiving hopper 20 via the discharge hopper 19, and are then mixed and conveyed by the conveying auger 17. The remaining cement is collected by the inclined first guide plate 14 and can slide down through the guide chute 15 and enter the second raw material chamber through the first through hole 12 to mix with the sand. At the same time, the remaining sand is collected by the inclined second guide plate 18 and can slide down through the guide chute 15 and enter the first raw material chamber through the second through hole 13 to mix with the cement. This allows for preliminary mixing before being conveyed by the mixing and conveying components, improving the uniformity of subsequent mixing and effectively reducing the mixing time when using a mixer.

[0038] In a specific embodiment of this utility model, see [reference needed]. Figure 4 As shown, each support frame includes:

[0039] Support plate 3, with two vertical strips 4 fixed parallel to the upper end face of support plate 3, forming a lifting groove 5 between the two vertical strips 4 and support plate 3;

The connecting rod is connected between the output end of the first motor 8 and the outer wall of the housing 1. The other movable mounting plate 7 is connected to the outer wall of the housing 1 through a bearing component. The bearing component includes a bearing and a connecting column. One end of the connecting column is fixed to the outer wall of the housing 1, and the other end of the connecting column is connected to the inner ring of the bearing. The outer ring of the bearing is connected to the movable mounting plate 7.

[0047] As described above, when cleaning the tank 1, the electric telescopic rod 6 can be started first, and the movable mounting plate 7 can be moved upward by the electric telescopic rod 6, so that the bottom end of the discharge hopper 19 moves out of the receiving hopper 20. Then, the first motor 8 can be started during rinsing, and the output end of the first motor 8 can drive the tank 1 to rotate, which can effectively improve the rinsing efficiency. There is no need for the staff to drag the water pipe around, making cleaning more convenient. When emptying impurities, the tank 1 can be turned so that the upper port with the larger opening of the tank 1 faces downward, which facilitates the emptying of impurities inside and on the first guide plate 14 and the second guide plate 18.
