DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, a water conservancy construction material conveying device includes a base 1, the bottom of the base 1 can be provided with a roller 11 to facilitate movement; a conveying cylinder 2 is provided on the mounting surface of the base 1, for example, the conveying cylinder 2 can be arranged obliquely upward, and a feed port 3 is provided at the end of the conveying cylinder 2 at a lower position, and a feed hopper 12 is also connected to the feed port 3, and a first discharge port 4 is provided at the end of the conveying cylinder 2 at a higher position. More specifically, a conveying blade 5 is rotatably provided in the conveying cylinder 2 through a driving source such as a motor, for example, the conveying blade 5 is a screw dragon.

[0026] During construction, concrete can be guided from the feed hopper 12 through the feed port 3 to flow into the conveying cylinder 2, and the rotating conveying blades 5 can convey the concrete to the first discharge port 4 for discharge. For example, a flexible pipe 29 can also be connected to the first discharge port 4, and the concrete can be conveyed to the construction site more controllably and conveniently through the flexible pipe 29.

[0027] In some specific construction processes, such as the pouring of large concrete structures, due to the characteristics of concrete materials and the limitations of structure size and shape, it is often necessary to adopt a layered pouring method. This method can effectively control the initial setting time and temperature stress of concrete, thereby ensuring the integrity and stability of the concrete structure.

[0028] The basic principle of layered pouring is to divide the entire concrete structure into several horizontal layers or inclined layers for pouring. After each layer is poured, it is necessary to wait for a period of time for the concrete to initially solidify and form a certain strength before pouring the next layer. This waiting time is the interval between pouring each layer. Therefore, it is necessary to constantly suspend the supply of concrete. It can be understood that in order to meet the above-mentioned process requirements, it is necessary to constantly start and stop the conveying blade 5. If the downtime of the conveying blade 5 is too long, the concrete may stand still and solidify in the conveying barrel 2, so it needs to be flushed every time it is stopped, which is extremely inconvenient.

[0029] In view of the above technical problems, in the present invention, Figure 2 , Figure 3 As shown, a discharge port 6 is further provided on the conveying cylinder 2 beside the first discharge port 4, and a collection box 7 is further provided on the base 1. The collection box 7 specifically includes a box body 30 and a connecting pipe 31 connected to the box body 30, and the connecting pipe 31 is adapted to be connected to the discharge port 6. In addition, a second discharge port 8 is further provided on the top side wall of the connecting pipe 31; a pump mechanism 9 is further provided in the collection box 7, and an opening and closing mechanism 10 is provided in the discharge port 6.

[0030] When the supply of concrete needs to be suspended, the opening and closing mechanism 10 can open the discharge port 6, the conveying blade 5 continues to operate, and the concrete will be stored in the aggregate box 7 through the discharge port 6. Since the concrete in the conveying blade 5 is still flowing, it is not easy for the concrete to stand still and solidify in the conveying cylinder 2; and when the concrete needs to be supplied again, on the one hand, the concrete in the conveying cylinder 2 can be discharged again from the first discharge port 4, and on the other hand, the pump mechanism 9 can pump the concrete in the aggregate box 7 out of the second discharge port 8, so as to realize the supply of large-flow concrete.

[0031] In some embodiments, the opening and closing mechanism 10 is a solenoid valve, and the pump mechanism 9 is a suction pump (not shown). In this example, the discharge port 6 and the first discharge port 4 can be arranged in sequence along the conveying direction of the conveying blade 5, so that when the supply of concrete needs to be suspended, for example, no additional control can be performed on the first discharge port 4 or the above-mentioned flexible pipe 29, and only the opening and closing mechanism 10 needs to be controlled to be in an open state, and the concrete will flow into and be stored in the aggregate box 7 because it flows through the discharge port 6 first; and when the concrete needs to be re-supplied, the opening and closing mechanism 10 can be controlled to be in a closed state, and then the pump mechanism 9 can be controlled to start pumping the concrete in the aggregate box 7 out of the second discharge port 8.

[0032] In other embodiments, the opening and closing mechanism 10 includes a sealing plate 13 elastically arranged in the discharge port 6. For example, the discharge port 6 can be specifically constructed in a T shape, and the sealing plate 13 is engaged with the top of the discharge port 6 by elastic parts such as springs; the pump mechanism 9 includes a connecting shaft 14 rotatably arranged in the box body 30, and the connecting shaft 14 penetrates the sealing plate 13 upward and extends into the conveying cylinder 2.

[0033] More specifically, the connecting shaft 14 is provided with a stirring unit 23, a pump unit 15, and a sealing portion 16 from bottom to top. The stirring unit 23 is arranged in the box body 30; the pump unit 15 can be adapted in the connecting pipe 31; the sealing portion 16 is adapted to the blocking plate 13, for example, a slot for fitting the sealing portion 16 is provided on the top surface of the blocking plate 13, and when the blocking plate 13 is in a natural state, the sealing portion 16 is inserted into the blocking plate 13 and the two cooperate to close the discharge port 6.

[0034] In some examples, the connecting shaft 14 can be rotated by a driving source such as a motor. When the concrete is normally transported to the first discharge port 4, since the concrete flows in the conveying cylinder 2, the blocking plate 13 maintains a closed position under the action of elastic force, and the discharge port 6 is closed; when the concrete needs to be temporarily supplied, the first discharge port 4 can be controlled to be in a closed state, for example, by setting a solenoid valve in the first discharge port 4, or setting a manual closing mechanism at the end of the flexible pipe 29 so that the first discharge port 4 can be closed, at this time, the pressure of the concrete in the conveying cylinder 2 increases, the blocking plate 13 will be squeezed until the sealing part 16 is out of the card slot, the passage of the discharge port 6 is open, and the concrete can flow into the aggregate box 7.

[0035] During the process of the concrete flowing into the discharge port 6, the motor can be controlled to drive the connecting shaft 14 to reverse. At this time, the pump unit 15 will not lift the concrete in the aggregate box 7 because its rotation direction is opposite to that when pumping out, and the concrete can flow into the box body 30 normally. At the same time, the rotating connecting shaft 14 will drive the stirring unit 23 to rotate and stir the concrete in the box body 30, so that the concrete in the aggregate box 7 is not easy to solidify.

[0036] In a specific example, the pump unit 15 includes a screw or an impeller adapted in the connecting pipe 31, or other pump structures driven by the rotating connecting shaft 14 to achieve the lifting of the fluid. When the motor drives the connecting shaft 14 to rotate forward, the pump unit 15 rotates synchronously and generates a lifting force on the concrete in the box body 30 until the concrete is discharged from the second discharge port 8.

[0037] In other examples, the top sliding sleeve of the connecting shaft 14 is provided with a connecting sleeve 17, for example, a key (not shown) is provided on the outer wall of the connecting shaft 14, and a connecting groove (not shown) adapted to the key is provided on the inner wall of the connecting sleeve 17, and the translation of the connecting sleeve 17 on the connecting shaft 14 is achieved through the cooperation between the key and the connecting groove. In addition, a connecting rod 22 is further provided between the connecting sleeve 17 and the blocking plate 13, so that when the above-mentioned blocking plate 13 is squeezed and bounced, the connecting rod 22 will drive the connecting sleeve 17 to move downward synchronously.

[0038] More specifically, the connecting sleeve 17 is provided with a first gear 18 and a second gear 19 in sequence along the axial direction; the rotating shaft of the conveying blade 5 is provided with a third gear 20 and a fourth gear 21 in sequence along the axial direction. In addition, a fifth gear 24 is also rotatably provided in the conveying cylinder 2, and the fifth gear 24 is meshed with the fourth gear 21. The present invention may have the following operation process:

[0039] S1, the first discharge port 4 remains open, and concrete is supplied normally. At the same time, the blocking plate 13 is in the closed position, and the first gear 18 is meshed with the fourth gear 21 and drives the connecting shaft 14 to rotate forward, so that the concrete in the aggregate box 7 can be pumped out from the second discharge port 8 through the pump unit 15;

[0040] S2, the first discharge port 4 is in a closed state, and the supply of concrete is suspended. At the same time, the blocking plate 13 is pressed in an open position, the first gear 18 is disengaged from the fourth gear 21 downward, and the second gear 19 is meshed with the fifth gear 24 and drives the connecting shaft 14 to reverse, so that the concrete can pass through the pump unit 15 and be stored in the aggregate box 7, and the mixing unit 23 mixes it synchronously.

[0041] For example, the stirring unit 23 may preferably include an L-shaped fixing rod 25 and a plurality of stirring blades 26 disposed on the fixing rod 25 , so that the stirring unit 23 can avoid the pump unit 15 and fully stir the concrete in the box body 30 .

[0042] In a more preferred example, the first gear 18 and the connecting sleeve 17 can also move in translation through a key similar to the connecting shaft 14 and the connecting sleeve 17, and the top of the connecting sleeve 17 is also provided with a first airbag 27 abutting against the first gear 18, and the bottom of the connecting shaft 14 is also provided with a second airbag 28 located in the box 30, and the first airbag 27 and the second airbag 28 are connected through a pipeline. For example, the pipeline can be arranged in the connecting shaft 14 and realize the connection between the first airbag 27 and the second airbag 28. Based on the above operation process, the present invention can also have:

[0043] S3. In S2, as the concrete flows into the box 30, the second airbag 28 is pressurized and presses the gas into the first airbag 27, and the expanded first airbag 27 pushes the first gear 18 to rise;

[0044] After S2 is switched to S1, the first gear 18 in the jacking position can be meshed with the fourth gear 21 and the concrete in S1 can be pumped out;

[0045] After the concrete in the box 30 is pumped out, the second airbag 28 will return to its natural state and re-inhale the gas, and the contracted first airbag 27 will drive the first gear 18 to descend, and the first gear 18 in the descending position will be separated from the fourth gear 21, thereby cutting off the power connection between the connecting shaft 14 and the rotating shaft of the stirring blade 26, thereby reducing the overall load and energy consumption of the present invention.

[0046] It should be noted that the contact surface between the blocking plate 13 and the elastic member at its bottom can be smoothed. For example, when the elastic member is a spring, a ball bearing (not shown) can be preferably provided at the top of the spring, so that the blocking plate 13 can be rotated when subjected to the elastic force. In a possible example, a connecting ring (not shown) can be rotatably provided on the top surface of the blocking plate 13, and the end of the connecting rod 22 away from the connecting sleeve 17 is connected to the connecting ring, so that the rotatability of the connecting sleeve 17 is satisfied by the rotatability of the connecting ring on the blocking plate 13.

[0047] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art shall not deviate from the spirit and scope of the present invention, and shall be within the scope of protection of the claims attached to the present invention.
