Abstract
Description
Technical Field
[0001] This utility model relates to the field of suction and pressure conveying vehicle technology, and in particular to a hydraulic drive system for a suction and pressure conveying vehicle. Background Technology
[0002] A suction-and-feed vehicle is a special vehicle designed for transporting powdery materials. It uses negative pressure suction and positive pressure discharge to collect, transfer, and convey materials.
[0003] Currently, most suction and pressure conveying vehicles on the market use rigid connections or simple flexible structure designs at the end of the conveying pipe, lacking an effective adaptive adjustment drive mechanism. This makes it difficult for the conveying pipe to flexibly adjust its angle and direction according to the on-site working conditions during operation. Especially in complex working environments, such as narrow spaces or irregular material stacking areas, blind spots in suction or deviations in the feeding position are likely to occur. This not only reduces the efficiency of operation but also increases the difficulty of operation for operators, failing to meet the needs of efficient and flexible operation.
[0004] Furthermore, when it is necessary to maintain, replace, or adjust the working position of the conveying pipe, the disassembly process of the mechanical connection structure is cumbersome, requires the use of special tools, is inconvenient to operate, seriously affects the continuity of operation, and is difficult to meet the dual requirements of modern operation for equipment convenience and stability.
[0005] To address the shortcomings of the aforementioned technologies, we propose a hydraulic drive system for a suction-pressing vehicle. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hydraulic drive system for a suction and pressure conveying vehicle.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:

An installation annular groove is formed on the inner side of the metal annular cavity, and a rubber annular plate is fixedly bonded to the inner side of the installation annular groove. Several sets of reinforcing connecting screws are screwed onto the side wall of the metal annular cavity, with the inner ends of the reinforcing connecting screws threaded through into the interior of the rubber annular plate. A threaded connecting pipe is fixedly connected to the side wall of the metal annular cavity, and a second solenoid valve is fixedly installed on the threaded connecting pipe.

[0011] Furthermore, an adapter is rotatably mounted on the lower side of the metal sleeve.
[0012] Furthermore, a hydraulic oil pump and a hydraulic drive rod are fixedly installed on the upper side of the suction and pressure conveying vehicle structure, and the upper end of the hydraulic drive rod is fixedly connected to the adapter seat.
[0013] Furthermore, a hydraulic output pipe is fixedly installed on the side of the output end of the hydraulic oil pump, and a first hydraulic pipe is installed between the hydraulic output pipe and the hydraulic drive rod, and a first solenoid valve is fixedly installed on the first hydraulic pipe.

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Reference Figures 1-4 A hydraulic drive system for a suction and pressure conveying vehicle includes a structural side plate 1 of the suction and pressure conveying vehicle and a hydraulic drive assembly 9 for the conveying pipe. The hydraulic drive assembly 9 for the conveying pipe includes a rubber tube 91, a metal sleeve 92 fixedly fitted on the right end of the rubber tube 91, an annular groove 94 formed on the outer wall of the left side of the rubber tube 91, a metal annular cavity 96 fitted on the outer side of the annular groove 94, an installation annular groove 97 formed on the inner side of the metal annular cavity 96, a rubber annular plate 98 fixedly bonded to the inner side of the installation annular groove 97, a number of sets of reinforcing connecting screws 99 screwed onto the side wall of the metal annular cavity 96, the inner ends of the reinforcing connecting screws 99 screwed through to the inside of the rubber annular plate 98, a threaded connecting pipe 910 fixedly connected to the side wall of the metal annular cavity 96, and a second solenoid valve 911 fixedly installed on the threaded connecting pipe 910.
[0025] With the above-described setup, when installing the rubber tube 91, the metal annular cavity 96 is fitted inside the annular groove 94. Subsequently, the rubber tube 91 is fitted onto the outer wall of the conveying pipe of the suction and pressure conveying vehicle. Then, the threaded connecting pipe 910 is screwed onto the connecting cap 8. Subsequently, the hydraulic oil pump 2 can be used to deliver hydraulic oil into the metal annular cavity 96 through the second hydraulic pipe 7, thereby causing the rubber ring plate 98 to bulge and stably fit the rubber tube 91 onto the outside of the conveying pipe. After the fit is stable, the second solenoid valve 911 is closed, so that the hydraulic pressure inside the metal annular cavity 96 remains stable, which can provide a stable fit for the rubber tube 91 and make the connection of the rubber tube 91 stable.
[0026] In this method, a hydraulic oil pump 2 and a hydraulic drive rod 3 are fixedly installed on the upper side of the side plate 1 of the suction and pressure conveying vehicle structure. The upper end of the hydraulic drive rod 3 is fixedly connected to the adapter 93. A hydraulic output pipe 4 is fixedly installed on the side of the output end of the hydraulic oil pump 2. A first hydraulic pipe 5 is installed between the hydraulic output pipe 4 and the hydraulic drive rod 3. A first solenoid valve 6 is fixedly installed on the first hydraulic pipe 5. A second hydraulic pipe 7 is fixedly installed on the upper side of the hydraulic output pipe 4. A connecting screw cap 8 is fixedly connected to the upper end of the second hydraulic pipe 7. The connecting screw cap 8 is screwed onto the outside of the threaded butt pipe 910.
[0027] With the above setup, after the rubber hose 91 is installed, the first solenoid valve 6 is opened. At this time, the hydraulic oil pump 2 can transmit power to the hydraulic drive rod 3 through the first hydraulic pipe 5, thereby adjusting the extension and retraction of the hydraulic drive rod 3, which in turn changes the inclination angle of the end of the rubber hose 91. During the adjustment process, the rubber hose 91 adapts to the deformation.
[0028] In this method, the rubber ring plate 98 is made of EPDM rubber.
[0029] Through the above-mentioned design, EPDM rubber material has excellent resistance to ozone, ultraviolet rays and weathering, and can maintain stability and elasticity under long-term exposure to harsh outdoor environments (such as sunlight, humidity and temperature changes).
[0030] In this method, several sets of annular protrusions 95 are evenly distributed on the inner wall of the left end of the rubber tube 91.
[0031] With the above-mentioned arrangement, the annular protrusion 95 allows the rubber tube 91 to form several interlocking sealing rings on the outside of the conveying pipe, thereby ensuring the sealing performance of the connection between the rubber tube 91 and the conveying pipe.
[0032] In this method, an adapter 93 is rotatably mounted on the lower side of the metal sleeve head 92, and several screw positioning holes are opened on the side of the suction and pressure conveying vehicle structure side plate 1.
[0033] The above-described configuration, including the screw-in positioning hole, facilitates the screw-in installation of this device onto the frame structure of the suction and pressure conveying vehicle.
[0034] The working principle of the hydraulic drive system for the suction and pressure conveying vehicle provided by this utility model is as follows:
[0035] During system installation, the left end of the rubber tube 91 in the hydraulic drive assembly 9 is first fitted onto the end of the conveying pipe of the suction and pressing vehicle. The annular protrusion 95 on the inner wall of the left end of the rubber tube 91 can form a preliminary interlocking seal with the outer wall of the conveying pipe. Then, the metal ring cavity 96 is fitted onto the outside of the annular groove 94 on the left side of the rubber tube 91, and the second hydraulic pipe 7 is screwed and fixed to the threaded butt pipe 910 on the metal ring cavity 96 by the connecting screw cap 8. The hydraulic oil pump 2 is started and the second solenoid valve 911 is opened. The hydraulic oil enters the metal ring cavity 96 through the hydraulic output pipe 4 and the second hydraulic pipe 7, causing the rubber ring plate 98 in the mounting annular groove 97 to expand under hydraulic pressure, thereby pressing the rubber tube 91 tightly against the outside of the conveying pipe. The second solenoid valve 911 is closed to maintain hydraulic stability in the metal ring cavity 96, completing the stable connection between the rubber tube 91 and the conveying pipe. At the same time, the reinforcing connecting screw 99 can prevent the rubber ring plate 98 from separating from the metal ring cavity 96 during long-term use.
[0036] During the operation direction adjustment phase, the first solenoid valve 6 is opened, and the hydraulic oil output by the hydraulic oil pump 2 is delivered to the hydraulic drive rod 3 through the hydraulic output pipe 4 and the first hydraulic pipe 5. By controlling the extension and retraction of the hydraulic drive rod 3, the adapter 93 fixedly connected to its upper end moves up and down. The adapter 93 is rotatably connected to the metal sleeve 92, which is fixedly sleeved on the right end of the rubber tube 91. Therefore, the extension and retraction of the hydraulic drive rod 3 will synchronously change the inclination angle of the end of the rubber tube 91. During this process, the rubber tube 91 adapts to deformation due to its own flexibility, realizing flexible adjustment of the suction or feeding direction of the suction and feeding vehicle conveyor pipe to meet the needs of different operation scenarios. If disassembly and maintenance are required, simply open the second solenoid valve 911, and the hydraulic oil in the metal ring cavity 96 is extracted by the hydraulic oil pump 2. After the rubber ring plate 98 returns to its original state, the rubber tube 91 can be easily removed.
[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
