TECHNICAL FIELD

[0001] The present application relates to a transport device for simultaneously transporting ready-mixed concrete and dry cement. BACKGROUND

[0002] In order to adjust the performance of the concrete, dry cement needs to be added to the ready-mixed concrete at the construction site. The traditional method is to transport the dry cement to the construction site separately and then add it to the mixing drum of the mixer truck. The defects of this method are: first, a separate dry cement transport vehicle is needed, which is costly and inefficient; second, a special feeding device is needed; third, it is not convenient to measure at the construction site, and a separate measurement system needs to be prepared at the construction site.

[0026] The technical solutions of the present application will be described in detail below with reference to the drawings:

[0027] As shown in Figure 1 , the present application provides a dry-wet separation concrete mixing and transporting device with a partition, which comprises a mixing drum 1 mounted on a vehicle frame, an inner sealing cover 4, an outer sealing cover 5, an in-out hopper 6-1, a storage bin 6-3 and a feeding cylinder 8 arranged at the tail end of the mixing drum 1.

[0028] The outer sealing cover 5 is located outside the inner sealing cover 4. As shown in Figure 2 , a swivel ring 1-1 is arranged at the outer edge of the tail end of the mixing drum 1. An inner sealing ring 2 is mounted at the outer edge of the inner sealing cover 4, which is in sealing contact with the inner wall of the swivel ring 1-1. An outer sealing ring 3 is mounted at the outer edge of the tail end of the outer sealing cover 5, which is in sealing contact with the outer wall of the swivel ring 1-1.

[0029] The in-out hopper 6-1 and the storage bin 6-3 can be independently arranged. In the present embodiment, however, they are integrated: as shown in Figure 1 , a shell 6 is fixedly mounted outside the outer sealing cover 5, and a partition 6-2 is arranged in the shell 6 to divide the inner cavity of the shell 6 into the in-out hopper 6-1 and the storage bin 6-3. A cover plate is arranged at the feeding opening 6-4 at the upper end of the storage bin 6-3. This integrated structure can better utilize the space.

[0030] The in-out hopper 6-1 is connected to the mixing drum 1 through the feeding cylinder 8 which sequentially penetrates the outer sealing cover 5 and the inner sealing cover 4. The inner sealing cover 4 is rotationally connected to the feeding cylinder 8 through a swivel support mechanism 7.

[0031] As shown in Figure 6 and 7 , the outer sealing cover 5 is provided with an out-feed opening 5-1 which is in communication with the in-out hopper 6-1 and a storage outlet 5-2 which is in communication with the storage bin 6-3.

[0032] As shown in Figures 3 to 5 , the inner sealing cover 4 is provided with an in-out feed opening 4-1.

[0033] The outer outlet 5-1, the storage outlet 5-2 and the inner inlet and outlet 4-1 are all fan-shaped.

[0034] As Figure 1 , the first limiting mechanism is arranged between the inner sealing cover 4 and the feeding cylinder 8, and is used for limiting the relative rotation range between the inner sealing cover 4 and the outer sealing cover 5. Specifically, the first limiting mechanism comprises two first stoppers 9 arranged on the feeding cylinder 8 (or the inner side of the outer sealing cover 5) and one second stopper 10 arranged on the inner sealing cover 4 (or one first stopper 9 and two second stoppers 10), and the first stopper 9 and the second stopper 10 are in position correspondence.

[0035] The inner sealing cover 4 and the outer sealing cover 5 can only rotate 180 degrees relative to each other under the limitation of the first limiting mechanism, and when the first stopper 9 and the second stopper 10 are in contact, the two cannot continue to rotate in the original direction.

[0036] The dry-wet separation type concrete mixing and transporting device further comprises a second limiting mechanism for limiting the relative rotation range of the outer sealing cover 5 relative to the frame. Specifically, the second limiting mechanism comprises a third stopper 11 arranged on the outer sealing cover 5 (or the shell 6) and a stop mechanism arranged on the frame for blocking the third stopper 11. The stop mechanism preferably uses an oil cylinder or an air cylinder, which can be extended to block the third stopper 11 as needed. Obviously, in order to stop the outer sealing cover 5 at different positions, two groups of oil cylinders can be used.

[0037] When the mixing drum 1 rotates, the inner sealing cover 4 and the outer sealing cover 5 will rotate synchronously with the mixing drum 1 under the action of the inner sealing ring 2 and the outer sealing ring 3, and when the third stopper 11 is blocked by the stop mechanism, the outer sealing cover 5 stops rotating, and further, if the outer sealing cover 5 stops rotating, the second stopper 10 continues to move to contact the first stopper 9, then the inner sealing cover 4 also stops rotating. By controlling the stop positions of the inner sealing cover 4 and the outer sealing cover 5, the inner inlet and outlet 4-1 and the inlet and outlet hopper 6-1 are in different positions, and the working state is switched.

[0038] Specifically, the device has three working states:

[0039] The first working state is the state when transporting or feeding concrete. As Figure 3 and 6, the stirring barrel 1 rotates forward, driving the inner sealing cover 4 and the outer sealing cover 5 to rotate forward, until the third stop block 11 is blocked by the stop mechanism, so that the outer sealing cover 5 cannot continue to rotate, at this time the opening of the inlet and outlet hopper 6-1 is upward; and the inner sealing cover 4 continues to rotate under the action of the stirring barrel 1, until the second stop block 10 collides with the first stop block 9, the inner sealing cover 4 also stops rotating. At this time, the inner inlet and outlet port 4-1 is located above the feeding cylinder 8, and the concrete added through the inlet and outlet hopper 6-1 will enter the stirring barrel 1 through the feeding cylinder 8. During transportation, the stirring barrel 1 can continue to rotate forward, and the inner sealing cover 4 and the outer sealing cover 5 remain stationary under the action of the limiting mechanism.

[0040] The second working state is used for adding dry cement. As shown in Figure 4 and 6 , the stop mechanism acts (such as another oil cylinder extending) to block the reverse movement of the third stop block 11, and then the stirring barrel 1 rotates reversely, at this time the opening of the inlet and outlet hopper 6-1 is still upward, the outer sealing cover 5 is stationary, and the inner sealing cover 4 rotates reversely with the stirring barrel 1, until the second stop block 10 collides with the first stop block 9 from another direction, and the inner sealing cover 4 also stops rotating. At this time, the inner inlet and outlet port 4-1 is below the feeding cylinder 8, and the position coincides with the storage outlet 5-2, and the dry cement previously added in the storage bin 6-3 will enter the stirring barrel 1 through the storage outlet 5-2 and the inner inlet and outlet port 4-1 in turn.

[0041] The third working state is used for discharging concrete. As shown in Figure 5 and 7 , the working principle in this state is similar to that in the first working state, the stirring barrel 1 drives the inner sealing cover 4 and the outer sealing cover 5 to rotate, the outer sealing cover 5 is first blocked by the stop mechanism, and then the inner sealing cover 4 also stops rotating under the action of the first limiting mechanism. Different from the first working state, the opening of the inlet and outlet hopper 6-1 is downward after stopping, and the inner inlet and outlet port 4-1 is below the feeding cylinder 8, and the concrete in the stirring barrel 1 is output through the inner inlet and outlet port 4-1, the outer outlet 5-1 and the inlet and outlet hopper 6-1 in turn.
