Description

Technical Field

[0001] The utility model relates to the technical field of material loading, in particular to a hydraulic control device for a quantitative loading station. Background Art

[0002] With the advancement of industrialization, some loading stations based on mechanical transmission have emerged. While these stations have improved loading efficiency to a certain extent, they still have many limitations. Mechanical transmission components are prone to wear over time, affecting loading accuracy. Furthermore, mechanical loading stations have poor adaptability to different material properties and cannot flexibly adjust loading methods based on factors such as material density and fluidity.

[0003] In the industrial sector, hydraulic technology has become the core power and control method for numerous mechanical devices. From large-scale metallurgical equipment and construction machinery to precision machine tools and injection molding machines, hydraulic systems play an indispensable role. They enable high-power power transmission, precise motion control, and complex movement patterns, meeting the requirements of efficient, high-precision processing and operation in industrial production.

[0004] Therefore, due to their numerous drawbacks, the mechanical transmission mechanisms installed in loading stations are gradually being replaced by hydraulic systems. Driven by the trend towards automation and informatization, the hydraulic control devices in quantitative loading stations are now integrated with sensors and the entire logistics and production management system. These sensors monitor the displacement of the hydraulic cylinders, the pressure and flow of the hydraulic system in real time, and feed this data back to the controller, enabling data interaction. Based on this feedback, the controller dynamically adjusts the valve openings in the hydraulic valve block using an adaptive adjustment algorithm, ensuring that materials are loaded into the transport container at the correct quantity and appropriate speed, enabling remote monitoring and other functions.

[0005] When loading materials onto a transport truck, the transport truck needs to move to the material feed port, and the hydraulic control device is used to adjust the degree of patency of the feed port to achieve quantitative output of the material. Although the application of the hydraulic control device can achieve quantitative flow of materials, there are still some problems in the actual material loading process. For example, the body of the transport truck is relatively long. If it is stationary, if you want to fill the bucket with materials, you need to use other equipment to push the materials in the bucket to other locations. This operation increases the material loading procedure and correspondingly increases the cost. If the transport truck is started and stopped multiple times according to the loading conditions, it will not only increase the cost of material loading, but also cause environmental pollution due to incomplete fuel combustion. In the case of multiple transport trucks loading materials in a row, the pollution is very serious. Utility Model Content

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0032] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0033] like Figure 1 、 Figure 2 As shown, in order to control the material output from the silo 1 to fall at different positions in the bucket of the transport vehicle 2, thereby avoiding the use of other equipment to push the material in the bucket to move to other positions, or avoiding the transport vehicle 2 from starting and stopping multiple times to adjust its position, this embodiment provides a new feeding mechanism 3. The feeding mechanism 3 is arranged at the feeding port of the silo 1 and is connected to the hydraulic pump station 4. The operation of the hydraulic pump station 4 controls the operation of the feeding mechanism 3 to adjust the state of the feeding mechanism 3 so that the material falls at different positions in the bucket of the transport vehicle 2. In addition, the feeding mechanism 3 can also be controlled by the hydraulic pump station 4 to change the degree of patency to achieve quantitative output of materials.

[0034] like Figure 3-9 As shown, the material delivery mechanism 3 specifically includes a first material delivery pipe 31, a second material delivery pipe 32, an annular plate 33, etc. The first material delivery pipe 31 and the second material delivery pipe 32 are both configured as L-shaped structures. The feed port of the first material delivery pipe 31 faces upward and is connected to the silo 1. The discharge port of the second material delivery pipe 32 faces downward and is installed at the bottom of the first material delivery pipe 31. Therefore, the first material delivery pipe 31 and the second material delivery pipe 32 cooperate to form a material delivery channel.

[0035] To allow materials to land at different locations within the hopper of transport vehicle 2, first delivery pipe 31 includes a vertical pipe 314 and an elbow 315. Vertical pipe 314 is connected to the delivery port of silo 1, and elbow 315 is positioned below vertical pipe 314 via a bearing connection. This allows elbow 315 to rotate relative to vertical pipe 314, facilitating adjustment of the material delivery direction. Furthermore, an insert 312 with an inner diameter equal to that of elbow 315 is positioned at the end of elbow 315. An annular groove 323 is provided on the inner side of second delivery pipe 32, into which insert 312 is movably inserted. This arrangement allows the second delivery pipe 32 to be controlled to move relative to the first delivery pipe 31 under the action of an external force. Combined with the adjustable material delivery direction, this arrangement allows materials to be loaded into different locations within the hopper.

[0036] To control the movement of the second material delivery pipe 32 relative to the vertical pipe 314, an annular plate 33 is mounted on the vertical pipe 314 via a bearing connection. An outer ring gear 331 is installed at the bottom of the outer side of the annular plate 33. A bracket 313 is fixed to the side of the vertical pipe 314. A hydraulic motor 332 is mounted on the bracket 313. A second gear is mounted on the output shaft of the hydraulic motor 332. The outer ring gear 331 meshes with the second gear. Therefore, when the hydraulic motor 332 is in operation, the annular plate 33 is forced to rotate about its axis. If the second material delivery pipe 32 is connected to the annular plate 33, the hydraulic motor 332 can be operated to control the second material delivery pipe 32 to rotate around the vertical pipe 314, changing the material delivery position.

[0037] In order to install the second feeding pipe 32 on the side of the annular plate 33, two parallel support plates 333 are fixedly arranged on the side of the annular plate 33, and a second sliding plate 334 is arranged between the two support plates 333 by being connected by bolts. A clamp is sleeved on the second feeding pipe 32, a connecting frame 321 is fixedly arranged above the clamp, a first sliding plate 322 is fixedly arranged on the top of the connecting frame 321, the first sliding plate 322 and the second sliding plate 334 have the same cross section and are adapted to the space formed by the two support plates 333, so that the first sliding plate 322 and the second sliding plate 334 can be stably and movably arranged between the two support plates 333. In addition, a first telescopic cylinder 335 is arranged between the first sliding plate 322 and the second sliding plate 334, and when the first telescopic cylinder 335 works, the position of the first sliding plate 322 and the second feeding pipe 32 can be adjusted under the condition that the second sliding plate 334 is stably arranged, so that the adjustment of the material output position is realized without the aid of other equipment or the multiple start-stop of the transport vehicle 2.

[0038] In order to facilitate the circulation of materials, the elbow pipe 315 can be arranged obliquely, that is, the second feeding pipe 32 is arranged at the lower end of the elbow pipe 315, and under the action of the gravity of the materials, the materials can be forced to move to realize output.

[0039] In order to be able to control the flow of the material output, two perforations 311 are symmetrically arranged on the side wall of the vertical pipe 314, and the two perforations 311 are located at two ends of the same diameter. An adjusting mechanism 5 is arranged through the two perforations 311, the adjusting mechanism 5 is connected with the hydraulic pump station 4, and under the operation of the hydraulic pump station 4, the adjusting mechanism 5 can adjust the smoothness of the vertical pipe 314, that is, the adjustment of the material output flow can be realized.

[0040] Specifically, the adjusting mechanism 5 includes two blocking plates 51 and two driving plates 52, the two blocking plates 51 are arranged through the two perforations 311 respectively, and the ends close to each other can be attached, and the ends away from each other are protruded from the vertical pipe 314. The two driving plates 52 are arranged at the ends of the two blocking plates 51 away from each other and protruding from the vertical pipe 314, and can control the two blocking plates 51 to move simultaneously under the action of external force, that is, to control the two blocking plates 51 to be close to each other or away from each other.

[0041] In order to force the two blocking plates 51 to move relative to each other, connecting plates 54 are arranged on the ends of the two driving plates 52 in an up-down distribution, that is, the two connecting plates 54 are connected with the two driving plates 52 respectively. A rack is arranged on the side close to each other of the two connecting plates 54, and the two racks are connected with a first gear 55 in meshing. When one connecting plate 54 moves, the other connecting plate 54 moves in the opposite direction under the transmission of the first gear 55, thereby controlling the two blocking plates 51 to be close to each other or away from each other.

[0042] In order to reduce the impact of material movement, two inclined plates 316 are symmetrically arranged on the inner side of the vertical pipe 314, and the bottoms of the two inclined plates 316 form a material conveying channel, and the blocking plate 51 is exactly arranged in the material conveying channel.

[0043] At the same time, a second telescopic cylinder 57 is provided on a certain driving plate 52 , and the other end of the second telescopic cylinder 57 is stationary relative to the silo 1 . Under the action of the second telescopic cylinder 57 , the two driving plates 52 can be controlled to move simultaneously.

[0044] To ensure relatively stable operation of the two connecting plates 54, a limiting groove 53 is provided on the side of each connecting plate 54 that faces away from each other. The limiting groove 53 is arranged along the length of the connecting plate 54, and a limiting wheel 56 is provided at each limiting groove 53. Therefore, the limiting wheels 56 control the two connecting plates 54 to maintain a relatively stable state. The limiting wheels 56, the first gear 55, and the second telescopic cylinder 57 are mounted on the same plate body, which is fixedly connected to the silo 1.

[0045] To control the operation of the telescopic cylinder and hydraulic motor 332, the hydraulic pump station 4 includes a base 41, a first pump 42, and an oil tank 43. The oil tank 43 and the first pump 42 are both mounted on the base 41, and the first pump 42 is in communication with the oil tank 43, the telescopic cylinder, and the hydraulic motor 332. Therefore, the first pump 42 can control the circulation of hydraulic oil and the operation of the telescopic cylinder and the hydraulic motor 332. Of course, according to the existing connection method between the hydraulic pump station 4 and the telescopic cylinder and the hydraulic motor 332, it is known that hydraulic valves, sensors, controllers, etc. are also required. The hydraulic valve group includes various directional control valves (such as Rexroth's 4WE series solenoid reversing valves), flow control valves (such as the MTCV series), and pressure control valves (such as the DBW series) to precisely control the flow direction, flow rate, and pressure of the hydraulic oil. Sensors include displacement sensors (such as Deminzhe 19 series), pressure sensors (such as MPX5700), flow sensors (such as Gems FT-210), etc. The displacement sensor can accurately measure the stroke of the hydraulic cylinder, and the error is controlled within a very small range. The pressure and flow sensors have high sensitivity and anti-interference capabilities, and can still accurately feedback data in complex loading station environments. It is used to monitor key parameters such as the displacement of the hydraulic cylinder, the pressure and flow of the hydraulic system in real time, and feed back the data to the controller. The controller (such as the BWB hydraulic controller) accurately controls the hydraulic valve group according to the preset load volume and the data fed back by the sensor. Because the connection method of the hydraulic valve, sensor, controller, telescopic cylinder, hydraulic motor, pump, etc. is a public conventional technology, it will not be introduced here.

[0046] In order to reduce the temperature of the hydraulic oil, a second pump 44 and a heat exchanger 45 are provided on the oil tank 43, and the second pump 44, the heat exchanger 45 and the oil tank 43 form a circulating passage. The heat exchanger 45 can be provided as a tube-shell heat exchanger, a plate heat exchanger, a plate-fin heat exchanger, etc., and a spraying device or a fan is installed on the side of the heat exchanger 45. The spraying device directly sprays a cooling medium such as cooling water on the outer surface of the heat exchanger, and the heat is taken away by the evaporation of the water. The fan forcibly ventilates to accelerate the heat exchange between the air and the outer surface of the heat exchanger, thereby reducing the temperature of the heat exchanger.

[0047] The preferred embodiments of the present application have been described above by way of example only, not for limitation, and for those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
