Description

Technical Field

[0001] This utility model relates to the field of mixing plant technology, and in particular to a mixer discharge port with anti-splash function. Background Technology

[0002] A concrete mixing plant mainly consists of five major systems: a mixing host, a material weighing system, a material conveying system, a material storage system, and a control system, as well as other auxiliary facilities. During long-term production, material splashing and spillage at the mixer's discharge port during loading often results in significant material buildup on the ground and walls, making cleaning difficult.

[0003] While existing technologies control the feeding time to reduce impact and prevent material splashing, the effect is not obvious and it affects the feeding efficiency. Existing technologies also reduce the leakage space by adjusting the height of the rubber tube, but after the rubber tube is adjusted, it cannot fit snugly with the pump truck inlet, making it difficult to guarantee the anti-splash effect. In addition, the rubber tube is often scraped off by the mixer truck's receiving hopper.

[0004] Therefore, it is necessary to invent a mixer discharge port with anti-splash function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a mixer discharge port with anti-splash function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixer discharge port with anti-splash function, comprising a mixer discharge chamber, a top plate fixedly installed at the top of the mixer discharge chamber, a mixer outlet fixedly installed in the middle of the top plate, a rubber tube sleeved at the bottom outer side of the mixer outlet, multiple inner rubber curtains fixedly installed at the bottom of the rubber tube, the multiple inner rubber curtains being arranged in a ring, multiple outer rubber curtains fixedly installed at the bottom outer side of the rubber tube, the multiple outer rubber curtains being staggered with the multiple inner rubber curtains, a connecting seat fixedly installed at the bottom outer side of each of the multiple inner rubber curtains, a connecting pin inserted into both ends of each of the multiple connecting seats, a traction rope fixedly installed at one end of each of the multiple connecting pins, a ring gear rotatably installed at the top of the outer side of the rubber tube, the top ends of each of the multiple traction ropes being connected to the lower surface of the ring gear, a transmission gear installed on one side of the ring gear, a drive motor installed below the transmission gear, and a worm gear transmission installed between the output shaft of the drive motor and the transmission gear.

[0007] Preferably, an annular seat is fixedly provided at the top of the outer side wall of the rubber tube, and multiple wire grooves are arranged around the outer side wall of the annular seat, with multiple traction ropes respectively disposed in the multiple wire grooves.

[0008] Preferably, an annular baffle is fixedly provided above the annular seat, and the drive motor is fixedly provided above the annular baffle.

[0009] Preferably, a plastic curtain is fixedly provided on the lower surface of the top plate, and multiple partition grooves are provided through the outer side of the plastic curtain.

[0010] Preferably, the bottom of the outer side of the plastic curtain is provided with a pump truck inlet, and the pump truck inlet is designed with an arched structure.

[0011] Preferably, a counterweight is fixedly provided at the bottom of the outer side wall of the outer rubber curtain.

[0012] Preferably, a hose clamp is fitted onto the top of the outer side wall of the rubber tube.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model incorporates a rubber cylinder, an inner rubber curtain, an outer rubber curtain, a traction rope, and a ring gear. The rubber cylinder is installed below the mixer's discharge port. The inner and outer rubber curtains below the rubber cylinder form a splash-proof structure. When the mixer is unloading, the pump truck inlet is aligned below the mixer's discharge port. At this time, the splash-proof structure formed by the inner and outer rubber curtains can seal the pump truck inlet, thereby improving the splash-proof effect of the device. Furthermore, the inner rubber curtain can open outward under the traction of the traction rope and the ring gear. During the pump truck's entry and exit, the bottom end of the inner rubber curtain is raised by controlling its outward opening, thus avoiding collision with the pump truck. During the unloading process, the inner rubber curtain can open outward and fit against the edge of the pump truck inlet, reducing the amount of concrete adhering to the inner rubber curtain, thereby reducing the cleaning frequency of the inner rubber curtain. This ensures the splash-proof effect of the device while reducing the maintenance cost of the device.

[0015] 2. This utility model incorporates a plastic curtain with an arched pump truck inlet at the bottom outer side. As the pump truck enters the mixer unloading chamber, the pump truck inlet can move through the pump truck inlet to below the mixer outlet. The arched design allows the plastic curtain to fit snugly against the rear of the pump truck, enhancing the shielding effect on the mixer outlet area and further improving the splash-proof effect of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-4 The mixer discharge port shown includes a mixer discharge chamber 1. A top plate 2 is fixedly installed at the top of the mixer discharge chamber 1. A mixer discharge port 3 is fixedly installed in the middle of the top plate 2. A rubber cylinder 4 is sleeved on the bottom of the outer side of the mixer discharge port 3. Multiple inner rubber curtains 6 are fixedly installed at the bottom of the rubber cylinder 4, and the multiple inner rubber curtains 6 are arranged in a ring. Multiple outer rubber curtains 7 are fixedly installed at the bottom of the outer wall of the rubber cylinder 4, and the multiple outer rubber curtains 7 are staggered with the multiple inner rubber curtains 6. The combination of the outer rubber curtains 7 and the inner rubber curtains 6 can form a sealed structure for the pump truck inlet.

[0023] Multiple inner rubber curtains 6 are each fixedly provided with a connecting seat 8 at their bottom outer side. Connecting pins 9 are inserted into both ends of each connecting seat 8. A traction rope 10 is fixed to one end of each connecting pin 9. A ring gear 11 is rotatably provided at the top of the outer wall of the rubber cylinder 4. The top ends of the multiple traction ropes 10 are connected to the lower surface of the ring gear 11. A transmission gear 12 is provided on one side of the ring gear 11. A drive motor 13 is provided below the transmission gear 12. A worm gear drive is provided between the output shaft of the drive motor 13 and the transmission gear 12. The worm gear drive is used to drive the motor. The transmission effect between the drive motor 13 and the transmission gear 12 is achieved, and the self-locking effect of the transmission gear 12 can be achieved. Both the drive motor 13 and the worm gear transmission adopt the corresponding structure in the prior art. The drive motor 13 is equipped with a corresponding power supply and controller. Furthermore, both the ring gear 11 and the transmission gear 12 adopt the corresponding structure in the prior art, and they are only used for power transmission. Without affecting the normal implementation of this embodiment, there is no limitation on the number of teeth and the center distance. To ensure the normal cooperation between the ring gear 11 and the transmission gear 12, grease can be applied between them to ensure lubrication.

[0024] An annular seat 14 is fixedly provided at the top of the outer side wall of the rubber tube 4. Multiple wire grooves 15 are arranged around the outer side wall of the annular seat 14, and multiple traction ropes 10 are respectively arranged in the multiple wire grooves 15.

[0025] An annular baffle 16 is fixedly provided above the annular seat 14, and the drive motor 13 is fixedly provided above the annular baffle 16. The annular baffle 16 is used to prevent concrete splashing from affecting the cooperation of the drive motor 13, the annular gear 11 and the transmission gear 12. A gap is provided between the annular baffle 16 and the rubber cylinder 4 for the traction rope 10 to pass through.

[0026] A plastic curtain 17 is fixedly installed on the lower surface of the top plate 2. Multiple partition grooves 18 are provided through the outer side of the plastic curtain 17. A pump truck inlet 19 is provided through the bottom of the outer side of the plastic curtain 17. The pump truck inlet 19 is designed with an arched structure. The arched structure can ensure that the plastic curtain 17 fits the tail of the pump truck inlet 19 to improve the sealing effect.

[0027] A counterweight 20 is fixedly provided at the bottom of the outer side wall of the outer rubber curtain 7. The counterweight 20 is used to ensure that the outer rubber curtain 7 can hang down naturally.

[0028] A hose clamp 5 is fitted onto the top of the outer side wall of the rubber tube 4, which is used to fix the rubber tube 4.

[0029] Working principle of this utility model:

[0030] When this device is in use, the rubber cylinder 4 is installed at the bottom of the mixer outlet 3 through the hose clamp 5. When the mixer is unloading, the pump truck is poured into the mixer unloading chamber 1. The rear of the pump truck passes through the pump truck inlet 19 and reaches below the mixer outlet 3. At this time, the plastic curtain 17 is tightly attached to the rear of the pump truck, and both the inner curtain 6 and the outer curtain 7 are attached to the edge of the pump truck inlet. At this time, the pump truck inlet can be sealed to achieve the anti-splashing effect during the mixer unloading process.

[0031] Before the pump truck enters the water, the drive motor 13 drives the transmission gear 12 to rotate, which in turn drives the ring gear 11 to rotate. The ring gear 11 then moves the top of the traction rope 10. The traction rope 10, through the connecting pin 9 and the connecting seat 8, pulls the bottom of the outer side of the inner rubber curtain 6. The traction rope 10 is restricted by the wire guide groove 15, and its bottom can only move upwards. This causes the bottoms of multiple inner rubber curtains 6 to be pulled upwards, thus opening them outwards. After the inner rubber curtains 6 have opened to a certain extent, their bottom height is raised upwards. At this point, the pump truck inlet will not collide with the inner rubber curtains. When the inner rubber curtain 6 collides with the pump truck and reaches the designated position, the drive motor 13 drives the transmission gear 12 to flip, causing the traction rope 10 to be released and reset. At this time, the inner rubber curtain 6 resets under the action of gravity until it is in contact with the pump truck inlet. At this time, the inner rubber curtain 6 can achieve the sealing of the pump truck inlet. During this process, the outer rubber curtain 7 remains in contact with the inner rubber curtain 6 under the action of gravity and opens along with the opening of the inner rubber curtain 6. After the inner rubber curtain 6 is in contact with the pump truck inlet, the outer rubber curtain 7 can cover the gaps between the multiple inner rubber curtains 6, thereby ensuring the sealing effect of the inner rubber curtain 6 on the pump truck inlet.

[0032] It should be noted that the mixer discharge chamber 1 and the mixer outlet 3 in this embodiment adopt the corresponding structure in the prior art. The mixer discharge chamber 1 is also equipped with the corresponding structure of the mixer such as the main unit and the metering system. This embodiment only provides the relevant structure of the mixer discharge position, and the rest of the structure adopts the corresponding structure in the prior art.

[0033] It should be further noted that the rubber cylinder 4 in this embodiment uses the corresponding material in the prior art. In order to facilitate the installation of structures such as the ring gear 11, a metal cylinder can be added to the top of the rubber cylinder 4. The above-mentioned technical means are common in the field and will not be described in detail here. In addition, water pipes, cameras and other auxiliary structures can be added to the mixer unloading chamber 1 in this embodiment to facilitate cleaning and monitoring during the mixer unloading process. If water pipes are added to the mixer unloading chamber 1, corresponding drainage troughs need to be set on the ground inside the mixer unloading chamber 1.
