Abstract
Description
Technical Field

[0002] The main function of the torpedo tank for transporting concrete is to achieve efficient and safe transportation of concrete between the PC plant mixing station and the placing boom. Through the overhead rail system, the torpedo tank can quickly transport concrete from the mixing station to the placing boom, thereby improving production efficiency.
[0003] During the concrete transport process, each overhead track corresponds to a batching plant discharge port, and the number of discharge ports needs to be set according to the number of tracks, which increases transportation costs. Furthermore, when the torpedo tank is running on the track to transport concrete, the corresponding batching plant discharge port is in a closed state, which reduces the concrete transport efficiency. Moreover, when the torpedo tank filled with concrete moves on the track, the concrete remaining in the discharge port is prone to fall downwards, which is not conducive to worker safety.
[0004] Therefore, it is necessary to provide a new torpedo-type concrete mixing plant discharge port device to solve the above problems. Utility Model Content

The housing is rotatably connected to a first gear and a second gear that mesh with each other.

[0013] Compared with related technologies, the torpedo-shaped canister conveying concrete mixing plant discharge port device provided by this utility model has the following beneficial effects:
[0014] This utility model provides a discharge port device for a torpedo tank concrete mixing plant. During the process of using the torpedo tank to transport concrete, after the inlet of the torpedo tank is aligned with the discharge port, the drive mechanism on the support platform surface is opened, driving the discharge funnel to rotate, aligning the discharge funnel with the discharge port. The drive mechanism at the bottom of the discharge funnel is then opened, causing the baffle to rotate, opening the bottom of the discharge funnel. Next, the drive mechanism at the bottom of the mixing plant is opened, causing the baffle at the bottom of the mixing plant to rotate, opening the bottom of the mixing plant. This allows concrete from inside the mixing plant to enter the torpedo tank through the discharge funnel and the discharge port. When the amount of concrete inside the torpedo tank is sufficient, the drive mechanism at the bottom of the mixing plant is opened, causing the baffle to rotate and close the top of the discharge funnel. Residue remains inside the discharge funnel.

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1 to 6 , Figure 1 A schematic diagram of a preferred embodiment of the torpedo tank conveying concrete mixing plant discharge port device provided by this utility model; Figure 2 for Figure 1 The diagram shows an enlarged view of the structure at point A. Figure 3 for Figure 1 The diagram shows an enlarged view of the structure at point B. Figure 4 for Figure 1 An enlarged schematic diagram of the structure at point C is shown. Figure 5 for Figure 2 The diagram shows an enlarged view of the structure at point D. Figure 6 for Figure 1 The diagram shows a top view of the support platform structure. A torpedo tank concrete mixing plant discharge port device includes a support platform 1. Multiple discharge ports 11 are installed on the surface of the support platform 1. Multiple sets of guide rails 21 are provided at the bottom of the support platform 1. Torpedo tanks 2 are slidably connected inside the guide rails 21, and each guide rail 21 corresponds to one discharge port 11. A discharge funnel 4 is rotatably connected to the surface of the support platform 1. The discharge ports 11 are distributed in an arc shape on the surface of the support platform 1. When the discharge funnel 4 rotates, it aligns with the discharge ports 11, allowing the discharge funnel 4 to transport concrete into the multiple discharge ports 11 (as shown in the attached diagram). Figure 6 (As shown).
[0024] Both the mixing station 3 and the discharge hopper 4 are equipped with a sealing mechanism 5 at their bottom ends. Both the sealing mechanism 5 and the discharge hopper 4 are connected to a drive mechanism 6. The drive mechanism 6 includes a housing 61. The housing 61 is installed on the surface of the support platform 1, at the bottom end of the mixing station 3, and at the bottom end of the discharge hopper 4. A first gear 62 and a second gear 63 are rotatably connected inside the housing 61. A stepper motor 64 is installed on the surface of the housing 61, and the output shaft of the stepper motor 64 is connected to the second gear 63. A fixed shaft 42 is fixedly connected to the top of the first gear 62 on the surface of the support platform 1. The center of the fixed shaft 42 is on the same straight line as the center of the mixing station 3. The top of the fixed shaft 42 supports the discharge hopper 4 through a support frame 41. To facilitate the rotation of the discharge hopper 4 at the bottom end of the mixing station 3 by the fixed shaft 42, the output shaft of the first gear 62 on the side wall of the mixing station 3 and the discharge hopper 4 is connected to a baffle 51. When the stepper motor 61 rotates, it drives the second gear 63 to rotate. The rotation of the second gear 63 drives the fixed shaft 42, the feeding funnel 4, or the baffle 51 to rotate. The diameter of the first gear 62 is larger than the diameter of the second gear 63. In order to make it easier for the first gear 62 to drive the second gear 63 to rotate, and to reduce the load on the stepper motor 61, the rotation angle of the stepper motor 61 can be controlled. The rotation angle of the feeding funnel 4 and the baffle 51 can be controlled by adjusting the rotation angle of the stepper motor 61.
[0025] The enclosing mechanism 5 includes a baffle 51. The bottom ends of the mixing plant 3 and the discharge hopper 4 are rotatably connected to the baffle 51. Protective plates 510 are installed on the side walls of both the discharge hopper 4 and the mixing plant 3. The top of the baffle 51 is located inside the protective plate 510. This is to facilitate the protection of the top of the baffle 51 by the protective plate 510, preventing a large amount of concrete from adhering to the top of the baffle 51 and facilitating the rotation of the baffle 51. One end of the baffle 51 is fixedly connected to a fixing buckle 53. A fixing block 52 is installed on the inner side wall of the discharge hopper 4, abutting against the side wall of the baffle 51. The fixing buckle 53 is slidably connected inside the fixing block 52. A cylinder 57 is installed on the side wall of the discharge hopper 4. The inner... A magnetic ring 58 and a locking block 54 are slidably connected; one end of the locking block 54 engages with the fixing buckle 53, and the other end of the locking block 54 is fixedly connected to the magnetic ring 58; a second spring 56 is fitted on the side wall of the locking block 54, and one end of the second spring 56 abuts against the side wall of the magnetic ring 58; a first electromagnet 55 and a second electromagnet 59 are respectively installed at both ends of the cylinder 57, and the first electromagnet 55 and the second electromagnet 59 attract the surface of the magnetic ring 58; when the baffle 51 rotates downward, the baffle 51 rotates and separates from the fixing block 52, opening the feeding hopper 4 or the mixing station 3; when the baffle 51 rotates upward and abuts against the fixing block 52 to close the interior of the feeding hopper 4 or the mixing station 3, the baffle... 51 drives the fixing buckle 53 into the interior of the fixing block 52. The first electromagnet 55 and the second electromagnet 59 are energized. At this time, the magnetism generated on the top surface of the second electromagnet 59 is the same as the magnetism on the bottom surface of the magnetic ring 58 (like poles repel), while the magnetism generated on the bottom surface of the first electromagnet 55 is opposite to the magnetism on the top surface of the magnetic ring 58 (opposite poles attract). Simultaneously, the stretched second spring 56 contracts, causing the locking block 54 and the magnetic ring 58 to move towards the fixing buckle 53. This causes the locking block 54 to engage with the fixing buckle 53, and the magnetic ring 58 to attract the first electromagnet 55, fixing the position of the locking block 54. Thus, the locking block 54 fixes the fixing buckle 53 and the baffle 51, causing the baffle 51 to... The feeding hopper 4 is closed. When it is necessary to open the feeding hopper 4, the first electromagnet 55 and the second electromagnet 59 are connected to opposite currents. At this time, the magnetism generated by the top surface of the second electromagnet 59 is opposite to the magnetism of the bottom surface of the magnetic ring 58, and the magnetism generated by the bottom surface of the first electromagnet 55 is the same as the magnetism of the top surface of the magnetic ring 58. This pushes the magnetic ring 58 and the locking block 54 to move towards the second electromagnet 59, pulling and causing the second spring 56 to contract. The thrust generated by the electromagnet is greater than the resistance to the movement of the locking block 54, causing the locking block 54 to enter the interior of the cylinder 57. The magnetic ring 58 attracts the second electromagnet 59 to fix the position of the locking block 54, thereby facilitating the rotation of the baffle 51 inside the feeding hopper 4.
[0026] A mixing station 3 is set above the support platform 1. The bottom end of the mixing station 3 is rotatably connected to the discharge funnel 4. A sealing gasket 31 is provided at the connection between the discharge funnel 4 and the mixing station 3. In order to increase the sealing of the connection between the discharge funnel 4 and the mixing station 3 by the sealing gasket 31, concrete is prevented from entering the connection between the two.
[0027] The bottom end of the feeding funnel 4 has an annular groove 45 inside, and a fixing ring 43 is slidably connected inside the groove 45. Multiple first springs 44 are installed inside the groove 45, and the bottom ends of the first springs 44 are connected to the fixing ring 43. The fixing ring 43 is slidably connected to the feeding port 11. When the feeding funnel 4 rotates and contacts the top end of the feeding port 11, the fixing ring 43 contacts and presses against the feeding port 11. The top sidewall of the feeding port 11 and the bottom sidewall of the fixing ring 43 are both arc-shaped. The arc-shaped surface of the feeding port 11 is pressed upwards and squeezed into the material. The first spring 44 is compressed inside the slot 45, which facilitates the sliding of the fixing ring 43 over the top of the discharge port 11. When the discharge funnel 4 is aligned with the discharge port 11, the first spring 44 extends and pushes the fixing ring 43 into the interior of the discharge port 11, which facilitates the concrete inside the discharge funnel 4 into the interior of the discharge port 11 and prevents concrete leakage. After the concrete is delivered, the discharge funnel 4 continues to rotate, and the fixing ring 43 with its arc-shaped sidewall is squeezed and moves upward, causing the fixing ring 43 to separate from the discharge funnel 4, which facilitates the rotation of the discharge funnel 4.
[0028] The sidewall of the fixing block 52 has a triangular structure, and the locking block 54 is slidably connected to the interior of the fixing block 52. In order to facilitate the concrete to slide through the sidewall of the fixing block 52, the fixing buckle 53 and the locking block 54 inside the fixing block 52 are protected, and the probability of concrete contacting the fixing buckle 53 and the locking block 54 is reduced.
[0029] The working principle of the torpedo tank concrete mixing plant discharge port device provided by this utility model is as follows: When the device is connected to an external power source, during the concrete conveying process using the torpedo tank 2, after the inlet of the torpedo tank 2 is aligned with the discharge port 11, the stepper motor 64 on the surface of the support platform 1 is activated. By controlling the rotation and angle of the stepper motor 64, the rotation and angle of the discharge hopper 4 are adjusted, gradually aligning the discharge hopper 4 with the discharge port 11. When the discharge hopper 4 rotates and contacts the top of the discharge port 11, the fixing ring 43 contacts and presses against the discharge port 11. The top sidewall of the discharge port 11 and the bottom sidewall of the fixing ring 43 are both arc-shaped. The arc-shaped surface of the discharge port 11 is compressed upwards, pressing into the slot 45 and compressing the first spring 44, facilitating the sliding of the fixing ring 43 across the top of the discharge port 11. When the discharge funnel 4 is aligned with the discharge port 11, the first spring 44 extends, pushing the fixing ring 43 into the interior of the discharge port 11, allowing concrete from the discharge funnel 4 to enter the discharge port 11, and closing the stepper motor 64 on the surface of the support platform 1. Controlling the electromagnet at the bottom of the discharge funnel 4 causes the locking block 54 to enter the interior of the cylinder 57 and separate from the fixing buckle 53, opening the stepper motor 64 at the bottom of the discharge funnel 4. The stepper motor 64 drives the baffle 51 to rotate downwards, opening the bottom of the discharge funnel 4. The electromagnet on the side wall of the mixing plant 3 is controlled to separate the locking block 54 at the bottom of the mixing plant 3 from the fixing buckle 53, and the locking block 54 enters the interior of the cylinder 57. Then, the stepper motor 64 at the bottom of the mixing plant 3 is opened, causing the baffle 51 at the bottom of the mixing plant 3 to rotate downwards, opening the top of the discharge hopper 51, so that the concrete inside the mixing plant 3 enters the interior of the torpedo tank 2 through the discharge hopper 4 and the discharge port 11. When the amount of concrete entering the torpedo tank 2 is appropriate, the stepper motor 64 at the bottom of the mixing plant 3 is opened, causing the baffle 51 to rotate upwards to close the top of the discharge hopper 4, preventing concrete from entering the interior of the discharge hopper 4. The electromagnet at the bottom of the mixing plant 3 is then operated to make the locking block 54 engage the fixing buckle 53, thus fixing the baffle 51 at the bottom of the mixing plant 3. The remaining concrete inside the discharge hopper 4 continues to move downwards into the torpedo canister 2. When concrete delivery stops, the stepper motor 64 at the bottom of the discharge hopper 4 is activated, causing the baffle 51 to rotate upwards and close the bottom of the discharge hopper 4. The electromagnet at the bottom of the discharge hopper 4 is manipulated to fix the baffle 51 in place by the locking block 54. After one torpedo canister is filled, the above operation is repeated, causing the discharge hopper 4 to continue rotating and aligning with the other discharge port 11 and the torpedo canister 2 to continue filling with concrete.
