Description

Technical Field

[0001] This invention relates to the field of mining machinery and equipment technology, and more specifically, to a special hopper for a charging trolley. Background Technology

[0002] In mining, tunnel excavation and other engineering operations, the charging trolley is an important piece of equipment, and the performance of its hopper has a key impact on the efficiency and safety of the entire operation process.

[0003] The existing dedicated material bins for charging trolleys have many shortcomings. In terms of temperature control, if the temperature is too high when the charging trolley is mixing materials, it will bring certain safety risks, such as triggering dangerous reactions of flammable and explosive materials, seriously threatening the lives of operators and the integrity of engineering facilities. On the other hand, if the temperature is too low, it will easily cause the internal materials to become more viscous and less fluid, resulting in poor material flow. This will not only affect the mixing efficiency, but may also cause pipeline blockage, forcing the entire charging process to be interrupted and delaying the project progress.

[0004] From a structural design perspective, the emulsification structure and feeding device of the traditional charging trolley hopper are separated. This layout makes the overall structure of the hopper relatively dispersed and occupies a large space. This not only increases the overall size and weight of the charging trolley, which restricts the trolley's mobility and flexibility in narrow spaces or complex terrain, making it unsuitable for operation in actual engineering environments, but also increases the manufacturing cost of the equipment, including material costs and space occupancy costs.

[0005] The existing dedicated material bins for charging trolleys have problems in temperature control, structural layout, and maintenance and protection, which seriously restrict the performance of charging trolleys in actual engineering operations. A new design for dedicated material bins for charging trolleys that can solve these problems is needed. Summary of the Invention

[0006] The purpose of this invention is to provide a special hopper for a drug loading trolley to solve the problems mentioned in the background art.

A drive motor is fixedly installed on the upper side of the trolley frame, located on the side of the mixing pipe. A heating blade is provided in the middle of the mixing pipe. A first drive rod is fixedly installed in the middle of the heating blade. An isolation pipe is fixedly installed in the middle of the mixing pipe. An electrically controlled switch valve is fixedly installed at the lower end of the isolation pipe. A liquid tank is opened on the upper side of the isolation pipe. A second drive rod is rotatably arranged in the middle of the liquid tank. A heating blade is fixedly installed on the side of the second drive rod. Heat-conducting components are fixedly installed on both sides of the mixing tube, and heating elements are wrapped around the outside of the heat-conducting components.

[0008] Furthermore, a drive unit is fixedly mounted on the side of the trolley frame, and the trolley frame and the drive unit are rotatably connected by a connecting rod.

[0009] By adopting the above technical solution, the trolley frame and the drive head are rotatably connected by a connecting rod. When the drive head moves forward, the trolley frame can rotate at a certain angle, which facilitates travel on different roads.

[0010] Furthermore, a loading protection cover is rotatably provided on one side of the upper end of the upper cover, and an inspection cover is rotatably provided on the other side of the upper end of the upper cover.

[0011] By adopting the above technical solution, the loading protection cover can seal and protect the inlet end of the liquid tank and the insulated material tank on the lower side, and the inspection cover can be used for inspection and maintenance of the interior of the upper tank.

[0012] Furthermore, a mixing fan blade is fixedly installed at the lower end of the preliminary mixing cylinder, an isolation plate is fixedly installed in the middle of the trolley frame, and a storage battery is fixedly installed at the lower end of the preliminary mixing cylinder.

[0013] By adopting the above technical solution, the mixing fan blades can separate and disperse the oily raw materials inside the initial mixing tank, making it easier for them to enter the interior of the lower mixing pipe.

[0014] Furthermore, the side of the insulated material box is fixedly connected to the preliminary mixing box, and a heat insulation box is fixedly installed on the outside of the mixing pipe. The bottom of the heat insulation box is fixedly installed on the upper side of the trolley frame by a support member.

[0015] By adopting the above technical solution, the heat insulation box can isolate the temperature between the mixing pipe and the trolley frame, and while keeping it warm, reduce the impact of the internal temperature on the trolley frame.

[0016] Furthermore, a mixing tube is fixedly installed on the outer side of the first drive rod, and the side of the first drive rod is fixedly connected to the second drive rod.

[0017] By adopting the above technical solution, the heating blades, isolation fan blades and heating blades can be driven to rotate by the first drive rod and the second drive rod, thereby enabling different stirring and mixing of the internal materials.

A feeding pipe is fixedly installed at the lower output end of the liquid tank, and a first electric control switch is fixedly installed on the upper side of the feeding pipe.

[0019] By adopting the above technical solution, the water-to-raw material inside the liquid tank can be pumped into the mixing tube through the feeding pipe. Since the second drive rod is located in the liquid tank and has a circular groove structure, the water-to-raw material can be quantitatively injected into the liquid tank through the first electronic control switch, which facilitates subsequent emulsification and mixing.

One end of the feeding groove is fixedly connected to the liquid tank, and the other end of the feeding groove is connected to the spray head.

[0021] By adopting the above technical solution, the water-oriented raw material inside the liquid tank will flow into the spray head through the feeding trough. Then, as the heating blades rotate, the water-oriented raw material will be pumped into the oil-oriented raw material from the spray head position, thereby emulsifying and mixing.

[0022] Furthermore, an electric heating box is fixedly installed on the lower side of the trolley frame, and an electric heating element is fixedly installed on the side of the electric heating box.

[0023] By adopting the above technical solution, the electric heating box can accurately heat the mixing tube through the heating element, thereby keeping the internal temperature of the corresponding cavity constant and thus maintaining the stability of the internal temperature.

[0024] Furthermore, a discharge pipe is fixedly installed on the side of the mixing pipe, a cleaning pipe is fixedly installed on the side of the discharge pipe, a discharge pipe is fixedly installed on one side of the discharge pipe, and a pair of second electric control switches are fixedly installed on both sides of the discharge pipe.

[0025] By adopting the above technical solution, the second electric control switch can switch the discharge pipe on and off in sections on both sides, thereby effectively preventing the mixed material from flowing out. Cleaning liquid can be injected into the discharge pipe through the cleaning pipe for cleaning.

[0026] Compared with the prior art, the advantages of this invention are: 1. In this invention, by setting a structure with a mixing tube, the oil-based raw materials inside can be stirred and separated first, and then the oil-based raw materials and water-based raw materials can be fully emulsified and mixed by heating blades, which facilitates subsequent filling.

A mixing tube 22 is fixedly installed on the outer side of the first drive rod 1701. The side of the first drive rod 1701 is fixedly connected to the second drive rod 1702. The first drive rod 1701 and the second drive rod 1702 can drive the heating blade 24, the isolation fan blade 28 and the heating blade 24 to rotate, so that the internal materials can be stirred and mixed in different ways.

The lower output end of the liquid tank 1001 is fixedly installed with a feeding pipe 2101. The upper side of the feeding pipe 2101 is fixedly installed with a first electric control switch 21. The water-to-raw material inside the liquid tank 1001 can be pumped into the mixing pipe 22 through the feeding pipe 2101. Since the second drive rod 1702 is located in the liquid tank 30 and has a circular groove structure, the water-to-raw material can be quantitatively injected into the liquid tank 30 through the first electric control switch 21, which is convenient for subsequent emulsification and mixing.

One end of the feeding groove 27 is fixedly connected to the liquid tank 30, and the other end of the feeding groove 27 is connected to the spray head 2501. The water-to-raw material in the liquid tank 30 will flow into the spray head 2501 through the feeding groove 27. Then, as the heating blade 24 rotates, the water-to-raw material will be pumped into the oil-to-raw material from the spray head 2501 to emulsify and mix. An electric heating box 16 is fixedly installed on the lower side of the trolley frame 7. An electric heating element 20 is fixedly installed on the side of the electric heating box 16. The electric heating box 16 can accurately heat the mixing tube 22 through the electric heating element 20, thereby keeping the internal temperature of the corresponding cavity constant and thus maintaining the stability of the internal temperature. A discharge pipe 18 is fixedly installed on the side of the mixing pipe 22, a cleaning pipe 19 is fixedly installed on the side of the discharge pipe 18, a discharge pipe 2 is fixedly installed on one side of the discharge pipe 18, and a pair of second electric control switches 23 are fixedly installed on both sides of the discharge pipe 18. The second electric control switches 23 can switch the discharge pipe 18 on and off in sections, thereby effectively preventing the mixed material from flowing out. Cleaning liquid can be injected into the discharge pipe 18 through the cleaning pipe 19 for cleaning.

[0032] Working principle of the invention: The operator opens the loading protection cover 101 and puts the oil-type raw material into the top of the insulated material box 10. At the same time, the water-type raw material is stored in the liquid tank 1001. The servo motor 3 is started, which drives the mixing fan blade 401 in the preliminary mixing cylinder 4 to rotate. The oily raw material inside the insulated material box 10 will enter the preliminary mixing tank 11. The mixing fan blade 401 separates and disperses the oily raw material put into the preliminary mixing tank 11, making it easier to mix thoroughly in the subsequent process. The raw material after preliminary mixing enters the mixing pipe 22 through the connecting pipe 12. When the heating element 20 on the side of the heating box 16 is working, the heat is transferred to the mixing tube 22 through the heat conduction element 2001 to heat and keep the two ends of the mixing tube 22 warm. At the same time, the heat insulation box 13 on the outside of the mixing tube 22 isolates the temperature between it and the trolley frame 7, maintaining the temperature inside the mixing tube 22. At this time, the oil-based raw material enters the mixing tube 22. The drive motor 17 drives the first drive rod 1701 to rotate, which in turn drives the heating blade 24 to rotate, so that the oil-based raw material reaches a suitable mixing temperature. At the same time, the first drive rod 1701 drives the second drive rod 1702 connected to it to rotate. As the heating blade 24 rotates, it pushes the oil-based raw material to the position of the isolation tube 29. At this time, the electric control switch valve 2901 opens, and the blades of the isolation fan 28 become denser, which can quickly push the oil-based raw material into the cavity where the heating blade 24 is located, and at the same time, it can facilitate the reverse flow of the oil-based raw material. When the first electrical control switch 21 is turned on, the water in the liquid tank 1001 is pumped into the mixing pipe 22 through the feeding pipe 2101. The second drive rod 1702 has a circular groove structure on the side of the liquid tank 30, which quantitatively flows into the liquid tank 30. The water in the liquid tank 30 flows into the spray head 2501 through the feeding groove 27. As the heating blade 24 rotates, the water is pumped into the oil from the spray head 2501 to achieve rapid and thorough emulsification and mixing. After mixing is completed, open the electric control switch valve 2901 and the second electric control switch 23 on one side of the discharge pipe 18. The mixed material is discharged from the discharge pipe 2 and the filling is completed by the injection device connected to the discharge pipe 2. The drive head 6 drives the trolley frame 7 to move via the connecting rod 8. During the journey, the trolley frame 7 can rotate at a certain angle according to the road conditions to enhance maneuverability. When maintenance is required inside the equipment, the inspection cover 102 can be opened to inspect the inside of the upper box 5.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
