Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chain bucket type car unloaders, and in particular relates to an intelligent blanking chain bucket type car unloader. Background Art
[0002] Chain bucket unloaders use a chain-driven bucket conveyor to lift materials from the wagon to a designated discharge point. The movement of the chain drives the bucket along the track, lifting the material vertically. Chain bucket unloaders are primarily used in coal mines, fertilizer plants, and other fields because they effectively improve the speed and safety of material handling, and they can operate reliably under high loads and in harsh environments.
[0003] Currently, chain bucket unloaders, used for handling coal, fertilizer, and other materials, use a bucket conveyor to lift the material in the carriage to a height above the conveyor belt. The material in the bucket is then transferred to the conveyor belt, and finally transported to the cargo hold via the conveyor belt to complete the unloading process. As the bucket transfers the material to the conveyor belt, it is buffered only by a baffle plate. This baffle plate wears out over time and requires frequent replacement. Without the baffle plate, the material in the bucket falls directly onto the conveyor belt, causing significant impact. After numerous improvements and designs, the chain bucket unloader has replaced the baffle plate with a discharge barrel. The barrel is mounted at the output end of the bucket and moves back and forth with the chain bucket mechanism. The material is buffered by the barrel before falling onto the conveyor belt. This reduces the impact of the material directly falling on the conveyor belt and shortens the drop distance, preventing large splashes from the material falling.
[0004] However, during the use of the discharge barrel, especially when conveying materials with relatively high viscosity such as fertilizers and coal powder, the materials are prone to accumulation in the discharge barrel. The chain bucket unloader is relatively large in equipment, and it is impossible to observe the degree of unblocking of the materials in the discharge barrel at all times. Installing sensors only on the inner wall of the discharge barrel will cause misjudgment due to the continuous output of materials and the adhesion of particles such as coal powder, thereby affecting the unloading efficiency.
[0005] Therefore, the present application proposes an intelligent blanking chain bucket unloader to solve the above problems. Utility Model Content
[0006] The purpose of developing this utility model is to address the problem of existing chain bucket unloaders, where the material barrel used to receive the material dropped from the bucket is prone to material accumulation and cannot be monitored at all times, thus affecting material transportation. The following is a brief overview of the utility model to provide a basic understanding of certain aspects of the utility model. It should be understood that this overview is not an exhaustive overview of the utility model. It is not intended to identify key or important aspects of the utility model, nor is it intended to limit the scope of the utility model.
[0007] The technical solution of this utility model:
[0008] An intelligent blanking chain bucket type unloader includes a gantry, a chain bucket mechanism, a discharge barrel mechanism and a transmission mechanism. The chain bucket mechanism is installed on the gantry, the discharge barrel mechanism is connected to the chain bucket mechanism, the input end of the discharge barrel mechanism is connected to the output end of the chain bucket mechanism, the output end of the discharge barrel mechanism is connected to the transmission mechanism, and the transmission mechanism is installed on the gantry.

[0009] Furthermore, the unloading barrel mechanism includes a unloading barrel and a unloading cone barrel. One end of the unloading barrel is connected to one end of the unloading cone barrel by welding, and the other end of the unloading barrel is arranged below the output end of the chain bucket mechanism, and the other end of the unloading cone barrel is arranged above the transmission mechanism.
[0010] Furthermore, the first-level material height sensing mechanism and the second-level material height sensing mechanism are arranged in the discharge barrel, the two first-level material height sensing mechanisms are arranged in a mirror image on the inner wall of the discharge barrel, and the second-level material height sensing mechanism is arranged on the single-side inner wall of the discharge barrel, and the second-level material height sensing mechanism is arranged vertically to the first-level material height sensing mechanism.
[0011] Furthermore, the first-level material height sensing mechanism and the second-level material height sensing mechanism have the same structure, both including a baffle, a sensor, a hinge seat, a touch rod and a spring.

[0014] The utility model has the following beneficial effects:
[0015] 1. The utility model is an intelligent blanking chain bucket type unloader. On the basis of the equipment of the existing chain bucket type unloader, a first-level material height sensing mechanism and a second-level material height sensing mechanism are designed. Through the material height sensing mechanisms at different heights, real-time monitoring of the material height in the discharge barrel mechanism is realized. When the material is higher than the material height sensing mechanism, the signal is transmitted to the upper computer, and the upper computer then sends a signal to the chain bucket motor to control the speed of the chain bucket motor or directly shut down the chain bucket motor to control the blanking output of the bucket, thereby avoiding excessive blockage in the discharge barrel mechanism, facilitating timely unblocking and cleaning, and improving the efficiency of material handling.
[0016] 2. The utility model is an intelligent blanking chain bucket unloader. The first-level material height sensing mechanism and the second-level material sensing mechanism both adopt the method of arranging sensors and touch rods up and down. When the material is accumulated to a certain height, the touch rod is lifted to make it touch the sensor, and then the sensor sends a signal to the host computer to control the speed or opening and closing of the chain bucket motor. The sensor is installed below the baffle to prevent it from being affected and impacted by material transportation, thereby improving the accuracy of the sensor. BRIEF DESCRIPTION OF THE DRAWINGS

However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention.

Those skilled in the art can choose according to their needs. For example, a welded connection is selected for a fixed connection, and a hinge connection is selected for a detachable connection.
[0026] Example 1, combined Figures 1-6 To illustrate this embodiment, an intelligent blanking chain bucket type unloader of this embodiment includes a gantry 1, a chain bucket mechanism 2, a discharge barrel mechanism 3 and a transmission mechanism 4. The chain bucket mechanism 2 is installed on the gantry 1, and the discharge barrel mechanism 3 is connected to the chain bucket mechanism 2. The input end of the discharge barrel mechanism 3 is connected to the output end of the chain bucket mechanism 2, and the output end of the discharge barrel mechanism 3 is connected to the transmission mechanism 4. The transmission mechanism 4 is installed on the gantry 1, and a first-level material height sensing mechanism 12 and a second-level material height sensing mechanism 13 are installed in the discharge barrel mechanism 3. The first-level material height sensing mechanism 12 is arranged below the second-level material height sensing mechanism 13, and the first-level material height sensing mechanism 12 is arranged below the second-level material height sensing mechanism 13, and the first-level material height sensing mechanism 12 is arranged above the second-level material height sensing mechanism 13, and they are respectively connected to the chain bucket motor 9 of the chain bucket mechanism 2 through the upper computer 19.
[0027] A trolley running mechanism 5 is installed at the bottom of the gantry 1, and the trolley running mechanism 5 is slidably connected to the slide rail 6 installed on the ground. The trolley running mechanism 5 is a walking wheel, which can drive the gantry 1 to move in a straight line through the cooperation between the walking wheel and the slide rail 6. A slide is also installed on the gantry 1. The trolley running mechanism 7 connected to the chain bucket mechanism 2 is slidably connected to the slide on the gantry 1, and also adopts the cooperation between the pulley and the slide to drive the chain bucket mechanism 2 to move in a straight line. A lifting mechanism 8 is installed on the gantry 1. The lifting mechanism 8 is used to control the bucket of the chain bucket mechanism 2 to move up and down, so that the input end of the chain bucket mechanism 2 can be raised and lowered in the car, so as to better contact and transport the materials in the car.
[0028] On the basis of the existing chain bucket type unloader, the first-level material height sensing mechanism 12 and the second-level material height sensing mechanism 13 are respectively installed on the inner wall of the discharge barrel 10 of the discharge barrel mechanism 3. The first-level material height sensing mechanism 12 is installed at 2 / 3 of the total height of the discharge barrel 10, which is close to the discharge cone 11. The second-level material height sensing mechanism 13 is installed at 1 / 3 of the total height of the discharge barrel 10, which is arranged above the first-level material height sensing mechanism 12 and is close to the input port of the discharge barrel 10. There are two first-level material height sensing mechanisms 12, which are mirror-arranged on the inner wall on both sides of the discharge barrel 10, and the second-level material height sensing mechanism 13 is installed on the single-side side wall of the discharge barrel 10, as shown in the attached figure. Figure 4 As shown;
[0029] In the initial state, the angles between the touch rod 17 of the first-level material height sensing mechanism 12 and the second-level material height sensing mechanism 13 and the side walls of the discharge barrel 10 are both greater than 45°. The bottom of the touch rod 17 is connected to the inner wall of the discharge barrel 10 through a spring 18, and the end of the touch rod 17 is hinged to the inner wall of the discharge barrel 10 through a hinge seat 16. The touch rod 17 is supported by the spring 18 so that the touch rod 17 has a certain angle with the inner wall of the discharge barrel 10. When the unloading work starts, the chain bucket motor 9 of the chain bucket mechanism 2 starts to work, driving the bucket on the chain bucket mechanism 2 to run, and continuously inputting the material in the car into the discharge barrel mechanism 3, and finally falls on the transmission mechanism 4 through the discharge barrel 10 and the discharge cone 11 of the discharge barrel mechanism 3. If there is a blockage problem at the outlet of the discharge cone 11 during the transportation process, the material accumulates in the discharge barrel mechanism 3. When the material height is lifted to below the touch rod 17 of the first-level material height sensing mechanism 12, as the material height continues to rise, the touch rod 17 is lifted and the spring 18 is stretched. When the upper end surface of the touch rod 17 touches the sensor 15, the sensor 15 of the first-level material height sensing mechanism 12 transmits a signal to the host computer 19. After receiving the signal, the host computer 19 transmits the signal to the chain bucket motor 9. The chain bucket motor 9 reduces the speed and slows down the material conveying amount of the chain bucket mechanism 2. If the material in the discharge barrel mechanism 3 is cleared by the vibration of the equipment, the material height in the discharge barrel 10 continues to drop. Under the action of the spring 18, the touch rod 17 is reset, and the sensor 15 of the first-level material height sensing mechanism 12 sends a signal. The chain bucket motor 9 is controlled by the host computer 19 to resume normal speed and continue to output material.
[0030] If the blockage in the discharge barrel mechanism 3 is serious, when the material height in the discharge barrel 10 reaches the secondary material height sensing mechanism 13, the touch rod 17 of the secondary material height sensing mechanism 13 touches the sensor 15, and the sensor 15 of the secondary material height sensing mechanism 13 sends a signal to the upper computer 19. The upper computer 19 controls the chain bucket motor 9 to turn off. At this time, the material height in the discharge barrel 10 is too high. The maintenance personnel use tools to dredge the discharge barrel 10, lower the material height, and then turn on the chain bucket motor 9 to continue working.
[0031] The chain bucket motor 9 is an adjustable-speed motor, whose opening, closing, and speed adjustment are controlled by the host computer 19. The host computer 19 uses a Siemens SIMATIC IPC427C, which has a rugged design suitable for harsh industrial environments. The sensor uses an industrial touch sensor, model Omron E2E-X2M1, which provides stable touch response.
[0032] The upper end surface of the baffle 14 is an arc surface, so that materials falling on the baffle 14 will not be accumulated, thereby reducing the loss of the baffle 14.
[0033] This embodiment is only an illustrative description of the present application and does not limit its scope of protection. Those skilled in the art may also make partial changes to it. As long as they do not exceed the spirit of the present application, they are all within the scope of protection of the present application.
