[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] First embodiment After the concrete production is completed, the blanking equipment is usually used to transfer the concrete from the mixer to the transport vehicle and then transport it to the construction site to ensure the smooth and uniform supply of the concrete. Since the existing blanking equipment seals by clamping the blanking hose, after discharging the concrete through the blanking hose for a long time, it is easy to cause mortar to adhere to the inner wall of the blanking hose, affecting its sealing effect. In order to improve the sealing effect when clamping the blanking hose and reduce the waste of concrete, as Figure 1 - Figure 4 shown, this embodiment provides blanking equipment for concrete production and processing, which is composed of a blanking hopper 1, a blanking pipe 2, a connecting frame 5, a discharge hose 3 and an opening and closing assembly 4. The blanking pipe 2 is arranged at the bottom of the blanking hopper 1, the connecting frame 5 is fixedly welded on the outer side wall of the blanking pipe 2, the discharge hose 3 is fixedly installed inside the blanking pipe 2, a connecting plate 6 rotatably connected to the top of the blanking hopper 1 is fixed on the top of the connecting frame 5, the connecting plate 6 is fixedly installed at the bottom discharge port of the concrete mixer through bolts, and the blanking pipe 2 can also provide a supporting effect on the blanking hopper 1 to ensure the stability of the rotation of the blanking hopper 1. A spiral stirring blade is fixedly installed inside the blanking hopper 1, and the spiral stirring blade is used to ensure that the concrete flows faster and prevent the concrete from adhering to the inner wall of the blanking hopper 1.

[0020] The opening and closing assembly 4 is arranged on the blanking pipe 2 and is used to synchronously open and close the blanking hopper 1 and the discharge hose 3 to make the blanking hopper 1 and the discharge hose 3 communicate with each other. The opening and closing assembly 4 includes a positioning circular plate 41 arranged at the top of the discharge hose 3 and fixed to the inner wall of the blanking pipe 2, a movable circular plate 42 arranged on the top of the positioning circular plate 41 and fixed to the blanking hopper 1, and discharge grooves 43 respectively opened on the positioning circular plate 41 and the movable circular plate 42 and communicating with each other. The discharge grooves 43 on the positioning circular plate 41 and the movable circular plate 42 are both arranged in three. When the blanking hopper 1 rotates a certain angle, it can drive the movable circular plate 42 to rotate, so that the discharge grooves 43 on the movable circular plate 42 and the positioning circular plate 41 are respectively staggered or connected, thereby closing or opening the bottom of the blanking hopper 1.

[0021] Second embodiment To ensure that the two movable clamping plates 441 clamp the discharge hose 3 more stably and improve the sealing performance of the discharge hose 3, as Figure 4 - Figure 5 shown, in this embodiment, a clamping assembly 44 for relaxing the bottom of the discharge hose 3 to open it is provided at the bottom of the blanking pipe 2. The specific implementation method is that the clamping assembly 44 includes movable clamping plates 441 respectively arranged on both sides of the bottom of the blanking pipe 2, and placement grooves respectively opened at one ends of the two movable clamping plates 441. When the two movable clamping plates 441 move to the horizontal state simultaneously, the discharge hose 3 is clamped and sealed. Movable vertical rods 442 are respectively arranged on both sides of the movable clamping plate 441. An arc-shaped track 443 is arranged at the bottom of the movable vertical rod 442. An activity shaft 444 with one end fixed to the movable clamping plate 441 is slidably arranged inside the arc-shaped track 443, and the other end of the activity shaft 444 penetrates the bottom of the movable vertical rod 442 and is rotatably connected thereto. When the movable clamping plate 441 moves, it drives the activity shaft 444 to slide inside the arc-shaped track 443, improving the stability of the movable clamping plate 441 during movement. When the two movable clamping plates 441 are in contact, they are respectively horizontally sealed on both sides of the bottom of the blanking pipe 2. A connecting cross shaft 445 is fixed between the tops of the two opposite movable vertical rods 442. Both ends of the connecting cross shaft 445 are rotatably connected to the connecting frame 5 through bearing seats.

[0022] A connecting vertical rod fixed to the connecting frame 5 is fixed on the arc-shaped track 443, making the arc-shaped track 443 more stable during use. Driving cylinders 446 are respectively arranged at the ends of the two movable clamping plates 441 that are away from each other. An activity seat 447 is fixed to the output shaft of the driving cylinder 446. A limit seat 448 fixed to the movable clamping plate 441 is rotatably arranged on the activity seat 447. The rotational connection between the limit seat 448 and the activity seat 447 ensures that the movement of the movable clamping plate 441 is more flexible and stable. A support frame 449 fixed to the connecting frame 5 is rotatably arranged on the driving cylinder 446, and the driving cylinder 446 is movably installed on the support frame 449.

[0023] When it is necessary to open the discharge hose 3, by simultaneously starting the two driving cylinders 446, the output shafts of the driving cylinders 446 drive the activity seat 447 and the limit seat 448 to move. The limit seat 448 pushes the movable clamping plate 441 to move. The movable clamping plate 441 drives the activity shafts 444 at its two ends to slide inside the two arc-shaped tracks 443 respectively, and the movable clamping plate 441 drives the two movable vertical rods 442 to rotate respectively through the activity shafts 444 at its two ends. The two movable vertical rods 442 drive the connecting cross shaft 445 at their tops to rotate.

[0024] Third Embodiment To make the sealing effect better when the entire blanking device is closed and prevent the concrete from leaking after the discharging is completed, as Figure 3 、 Figure 4 and Figure 6As shown in the figure, in this embodiment, a rotating assembly 45 is provided at the top of the blanking pipe 2. The rotating assembly 45 is used to drive the blanking hopper 1 to rotate while relaxing the discharge hose 3. The discharge slots 43 on the movable circular plate 42 and the discharge slots 43 on the positioning circular plate 41 are in communication with each other, so that the blanking hopper 1 and the discharge hose 3 are connected. The specific implementation method is that the rotating assembly 45 includes a support ring body 451 provided on the outer side of the bottom of the blanking hopper 1 and fixed to the connecting frame body 5. While providing support for the blanking hopper 1, the support ring body 451 also provides a protective effect on the rotating assembly 45, a worm 452 fixed in the middle of one of the connecting cross shafts 445, and an end face gear 453 rotatably provided on the outer side of the top of the blanking pipe 2. A plurality of connecting blocks 454 fixed to the blanking hopper 1 are fixed to the top of the end face gear 453. A through groove 456 is opened at one end of the bottom of the connecting frame body 5. A transmission gear 455 meshing with the end face gear 453 is provided inside the through groove 456. A transmission shaft 457 rotatably connected to the connecting frame body 5 through a bearing is fixed at the axis of the transmission gear 455. A worm gear 458 meshing with the worm 452 is fixed to one end of the transmission shaft 457. When the connecting cross shaft 445 rotates, it drives the worm 452 and the worm gear 458 to rotate simultaneously. The worm gear 458 rotates through the transmission shaft 457 and the transmission gear 455. The transmission gear 455 drives the end face gear 453 to rotate. The end face gear 453 drives the blanking hopper 1 to rotate a certain angle through the connecting blocks 454, so that the discharge slots 43 on the movable circular plate 42 and the positioning circular plate 41 are respectively in communication with each other. The concrete in the blanking hopper 1 can be discharged through the discharge hose 3.

[0025] In the present invention, the clamping assembly 44 is used to close or open the discharge hose 3, and at the same time, the rotating assembly 45 is cooperated to close or open the blanking hopper 1. After the concrete blanking is completed, while clamping and sealing the discharge hose 3, the bottom of the blanking hopper 1 is sealed by the positioning circular plate 41 and the movable circular plate 42, so as to perform double-layer closing on the blanking equipment, improve the sealing effect when the blanking hose is clamped, prevent the concrete from leaking before discharging, and reduce the waste of concrete.

[0026] After the concrete is discharged, the two driving cylinders 446 are started synchronously. The output shaft of the driving cylinder 446 pushes the movable seat 447 to move. The movable seat 447 pushes the limiting seat 448 on one side to move. The limiting seat 448 pushes the movable clamping plate 441 to move. The movable clamping plate 441 drives the movable shafts 444 at both ends to slide inside the two arc-shaped tracks 443 respectively. The two movable clamping plates 441 move to a horizontal state, and the discharge hose 3 is squeezed between the two movable clamping plates 441. The discharge hose 3 is respectively located in the two placement grooves, so that the discharge hose 3 is in a sealed state.

[0027] Meanwhile, the movable clamping plate 441 drives the rotation of two movable vertical rods 442 respectively through the movable shafts 444 at both ends thereof. The two movable vertical rods 442 drive the rotation of the connecting horizontal shaft 445 at their tops. The connecting horizontal shaft 445 drives the rotation of the worm 452 thereon. The worm 452 drives the rotation of the worm gear 458 meshed therewith. The worm gear 458 drives the rotation of the transmission gear 455 through the transmission shaft 457 thereon. The transmission gear 455 drives the rotation of the face gear 453 meshed therewith. The face gear 453 drives the hopper 1 to rotate a certain angle through the connecting block 454, so that the movable circular plate 42 and the discharge slots 43 on the positioning circular plate 41 are staggered from each other respectively, making the hopper 1 in a sealed state and closing the outlet of the blanking device.
