Description

Technical Field

[0001] The utility model relates to the technical field of train sand filling, and specifically to a pure electric automatic sand filling device. Background Art

[0002] Train, also known as railway train, refers to a vehicle running on railway tracks, usually composed of multiple carriages, and is one of the important modern means of transportation for humans. As of 2023, there are two types of domestic trains: ordinary trains and EMU trains. It is one of the most important means of transportation in human history. In the early days, it was called a steam locomotive and had an independent track. According to the load, railway trains can be divided into freight trucks and passenger cars. There are also passenger and freight mixed cars that carry both, but they will produce a lot of carbon dioxide and pollute the environment. With the popularization of trains, people's travel mode, which was mainly powered by livestock, has changed. The early train carriages in China were green, so they were called green-skinned trains. The early traditional trains were composed of one to three locomotives pulling a number of carriages or wagons. Modern new trains have appeared in EMU trains with multiple carriages and self-powered. In Shanghai, there is already a maglev train line from Longyang Road Metro Station to Shanghai Pudong International Airport.

[0003] The earliest coal-fired steam locomotives that used coal-fired steam power had a big disadvantage, which was that coal and water facilities had to be set up along the railway, and a lot of time had to be spent on adding coal and water to the locomotive during operation. These were all very uneconomical. At the end of the 19th century, many scientists turned to the study of electric and fuel locomotives. At this stage, the train needs sand to increase its friction during operation to facilitate the start and stop of the train. At present, sand still needs to be loaded to assist the train.

[0004] The patent specification with announcement number CN213538973U discloses a detachable gravel filling device, including multiple columns erected on the foundation, and a hopper that is detachably connected to the multiple columns, multiple columns are arranged around the hopper at intervals in annular direction, and the hopper is suspended in the space enclosed by the multiple columns; the upper end of the hopper is provided with an inlet, the lower end of the hopper is provided with a discharge pipe for cooperating with the orifice of the filter bag, and the discharge pipe is provided with a valve for closing or opening the discharge pipe; the discharge pipe is provided at one end of the bottom of the hopper, and the end of the bottom surface of the hopper close to the discharge pipe is inclined downward relative to the end of the bottom surface of the hopper away from the discharge pipe. The device has a simple structure, is easy to disassemble and install, and is low in cost. A single worker can complete the entire set of processes such as assembly and filling, and it is more efficient when two or more people work together.

[0005] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device needs manual work to load the sand during use, and cannot realize the function of automatic loading. At the same time, due to the uneven storage conditions of the sand, if the sand that has been stored for a long time becomes damp or lumpy, it will affect the function of the sand, and the staff needs to crush it by manpower or external force before loading it. In addition, the flow rate of the sand is difficult to control, which will cause accumulation in a single position, which is not conducive to improving the overall work efficiency. Therefore, further improvement is needed. Utility Model Content

[0019] The working principle and beneficial effects of the utility model are:

[0020] 1. In the utility model, since the shape of the notch connected to the inside of the top plate limits the flow rate of the sand to a certain extent, the sand will flow slowly on the top of the filter screen, so that the flow rate of the sand in the feeding process can be limited, ensuring the subsequent separation of the sand, and solving the problem of inconvenience in crushing the sand and controlling the falling flow rate of the sand.

[0021] 2.

Since the positioning plate will limit the crushing plate at this time, the crushing plate will synchronously drive the telescopic spring to stretch during the rotation process. When the crushing plate completely slides over the outer surface of the positioning plate, the telescopic spring will be rapidly compressed. During the compression process, the telescopic spring will synchronously drive the crushing plate to rotate and reset. In this process, the sand material will be crushed by the force between the crushing plate and the positioning plate, so that the volume of the sand material is qualified and falls through the inside of the filter. If it is not crushed, the sand material accumulated on one side of the positioning plate will be crushed because the crushing plate continuously slides over the outer surface of the positioning plate and the telescopic spring drives the crushing plate to quickly reset, thereby ensuring the fineness of the sand material.

[0022] 3. In the utility model, the movable rod will synchronously drive the movable roller and the rolling counterweight bar to rotate during the rotation process. The rolling counterweight bar will roll due to the friction between it and the filter screen during the rotation process, and then the rolling counterweight bar will roll the agglomerated sand material, thereby further ensuring the overall texture of the sand material, facilitating the efficiency of the train during travel, and solving the problem of inconvenience in crushing the sand material and controlling the falling flow rate of the sand material.

DETAILED DESCRIPTION

[0033] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example 1

[0035] like Figure 1 to Figure 5 As shown, this embodiment proposes a pure electric automatic sand filling device, including an automatic sand material vehicle 1, a rotating plate 2 is movably connected to one side of the top of the automatic sand material vehicle 1 through a rotating shaft, a connecting handle 3 is fixedly connected to one side of the top of the rotating plate 2, a sand flow mechanism 7 is provided inside the automatic sand material vehicle 1, and a crushing mechanism 8 is also provided inside the automatic sand material vehicle 1, which can facilitate the staff to pull the connecting handle 3 to drive the rotating plate 2 to rotate, and then the external sand material can be poured into the interior of 1 for filling;

[0036] The quicksand mechanism 7 comprises a fixed shell 701, which is located inside the automatic sand material vehicle 1, and the top of the fixed shell 701 is fixedly connected to one side of the top of the inner cavity of the automatic sand material vehicle 1, and a fixed frame 702 is fixedly connected inside the fixed shell 701, and a filter screen 703 is embedded inside the fixed frame 702, and a plurality of positioning plates 704 are fixedly connected to the top of the filter screen 703, and a plurality of positioning plates 704 are fixedly connected to the top of each of the plurality of positioning plates 704, and a connecting plate 705 is fixedly connected to the top of each of the plurality of connecting plates 705, and a connecting top plate 706 is fixedly connected to the top of each of the plurality of connecting plates 705, and a plurality of discharge troughs are provided inside the connecting top plate 706, and a conical mounting plate 707 is fixedly connected to the top of the connecting top plate 706, and a plurality of fixed rods 708 are also fixedly connected to the top of the connecting top plate 706, and a feed hopper 709 is fixedly connected to the top of each of the plurality of fixed rods 708, so that the quicksand mechanism 7 can control the flow rate of the external sand material, and prevent the flow rate from being too fast, resulting in a large amount of sand material filling the top of the filter screen 703 before the crushing mechanism 8 starts to process the sand material, which affects the crushing work of the agglomerated sand material;

[0037] In this embodiment, a plurality of discharge troughs are arranged in a circumferential distribution, which can facilitate the discharge trough to control the speed of the sand material.

[0038] During use, when it is necessary to fill sand into the device, the staff first needs to hold the connecting handle 3 and then turn it to open it. During the rotation process, the connecting handle 3 will synchronously drive the rotating plate 2 to rotate. After the rotating plate 2 rotates, the fixed shell 701 will be exposed in an open state, and then the staff will pour the external sand into the interior of the feed hopper 709. At this time, the sand will be discharged through the feed hopper 709 and the fixed rod 708, and the discharged sand will be guided by the conical mounting plate 707 through the interior of the connecting top plate 706. Since the shape of the notch inside the connecting top plate 706 limits the flow rate of the sand to a certain extent, the sand will slowly flow on the top of the filter screen 703, thereby limiting the flow rate of the sand during the feeding process, thereby ensuring the subsequent separation of the sand.

[0039] Example 2

[0040] like Figures 4 to 7 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the crushing mechanism 8 includes a positioning motor 801, and the positioning motor 801 is fixedly connected to the bottom of the filter screen 703. The positioning motor 801 is fixedly connected to the rotating rod 802 through the output shaft, which can facilitate the installation and fixation of the positioning motor 801. At the same time, it can facilitate the discharge of sand and the rotation of the rotating rod 802.

[0041] In this embodiment, the rotating rod 802 passes through the interior of the filter 703 and is connected to the filter 703 via a bearing. The rotating rod 802 is fixedly connected to the outside with a rotating block 803. The rotating block 803 is fixedly connected to the inside with a plurality of rotating shells 804. The plurality of rotating shells 804 are distributed in a circular shape, which can facilitate the connection and support work between the rotating rod 802 and the filter 703, and at the same time, can facilitate the rotation work of the rotating shell 804.

[0042] In this embodiment, a plurality of rotating shells 804 are each provided with a crushing plate 805, and the crushing plate 805 is movably connected to the rotating shell 804 via a rotating shaft. A telescopic spring 806 is fixedly connected to one side of the crushing plate 805, which can facilitate the rotation of the crushing plate 805 and the deformation of the telescopic spring 806.

[0043] In the present embodiment, one end of the telescopic spring 806 is fixedly connected to one side of the interior of the rotating shell 804. A through slot is provided on one side of the interior of the rotating shell 804. One end of the crushing plate 805 extends to the outside of the through slot, which can facilitate the fixed connection of the telescopic spring 806, that is, it can be easily deformed later. At the same time, it can facilitate the rotation of the crushing plate 805. The through slot can ensure that the crushing plate 805 is not blocked during rotation.

[0044] In this embodiment, one side of the crushing plate 805 contacts one side of the positioning plate 704, and the bottom of the rotating shell 804 contacts the top of the filter screen 703, which can facilitate the rotation of the rotating shell 804 and the subsequent rotation and tilting of the crushing plate 805.

[0045] During use, when the sand material continuously falls on the top of the fixed frame 702, the fine enough sand material will penetrate into the interior of the automatic sand material vehicle 1 through the filter screen 703, while the sand material with a larger volume will stay on the top of the filter screen 703. At this time, the staff needs to turn on the positioning motor 801. After turning on, the positioning motor 801 will synchronously drive the rotating rod 802 to rotate. The rotating rod 802 will synchronously drive the rotating block 803 to rotate during the rotation process. The rotating block 803 will synchronously drive the rotating shell 804, the crushing plate 805 and the telescopic spring 806 to rotate during the rotation process. The crushing plate 805 will synchronously scrape the sand material during the rotation process. The crushing plate 805 will drive the sand material to fit with the positioning plate 704 during the rotation process. The positioning plate 704 will limit the crushing plate 805, so the crushing plate 805 will synchronously drive the telescopic spring 806 to stretch during the rotation. When the crushing plate 805 completely slides over the outer surface of the positioning plate 704, the telescopic spring 806 will be rapidly compressed. During the compression, the telescopic spring 806 will synchronously drive the crushing plate 805 to rotate and reset. In this process, the sand will be crushed by the force between the crushing plate 805 and the positioning plate 704, so that the volume of the sand is qualified and falls through the filter screen 703. If it is not crushed, the sand accumulated on one side of the positioning plate 704 will be crushed because the crushing plate 805 continues to slide over the outer surface of the positioning plate 704 and the telescopic spring 806 drives the crushing plate 805 to reset quickly, thereby ensuring the fineness of the sand.

[0046] like Figure 6 and Figure 8 As shown, based on the same concept as the above-mentioned embodiment 2, this embodiment also proposes that a crushing mechanism 9 is provided on both sides of the outside of the rotating block 803, and the crushing mechanism 9 includes a fixed seat 901, one end of the fixed seat 901 is fixedly connected to one side of the outside of the rotating block 803, and a movable rod 902 is connected to the inside of the fixed seat 901 through a bearing, which can facilitate the installation and fixation of the fixed seat 901, and at the same time, it can facilitate the movement of the movable rod 902.

[0047] In this embodiment, a movable roller 903 is fixedly connected to the outside of the movable rod 902, and a plurality of rolling counterweight strips 904 are fixedly connected to the outside of the movable roller 903. The plurality of rolling counterweight strips 904 are distributed in a circular shape, and the outer surfaces of some rolling counterweight strips 904 are in contact with the outer surface of the filter screen 703, so that the rolling counterweight strips 904 can drive the movable roller 903 to rotate through friction, thereby making it easier for the rolling counterweight strips 904 to roll and crush the agglomerated sand.

[0048] In this embodiment, a delivery pump 4 is fixedly connected to the bottom of the inner cavity of the automatic sand material vehicle 1, and a discharge pipe 5 is connected to the inside of the delivery pump 4 through a bearing, which can facilitate the discharge of the sand material by the discharge pipe 5 and facilitate the rotation of the discharge pipe 5.

[0049] In this embodiment, the discharge pipe 5 extends to the outside of the automatic sand material cart 1, and the discharge pipe 5 is connected to the automatic sand material cart 1 through a bearing. The outer end of the discharge pipe 5 is fixedly connected to a sand filling pipe 6, which can facilitate the discharge work of the sand filling pipe 6 and facilitate the sand filling pipe 6 to guide and discharge the sand through it.

[0050] When in use, the rotating block 803 will synchronously drive the fixed seat 901 to rotate during the rotation process, and the fixed seat 901 will synchronously drive the movable rod 902 to rotate during the rotation process, and the movable rod 902 will synchronously drive the movable roller 903 and the rolling counterweight bar 904 to rotate during the rotation process. The rolling counterweight bar 904 will roll due to the friction between it and the filter screen 703 during the rotation process, and then the rolling counterweight bar 904 will roll the agglomerated sand material, so as to further ensure the overall texture of the sand material and facilitate the efficiency of the train during travel;

[0051] Qualified sand will be retained inside the automatic sand material vehicle 1, and then the staff will move the device to the position where work is required, and then the staff will turn on the delivery pump 4 and align the sand filling pipe 6 with the position where sand needs to be filled, and then the delivery pump 4 will transfer the fine sand inside the automatic sand material vehicle 1 to the inside of the sand filling pipe 6 through the discharge pipe 5, and then discharge it through the sand filling pipe 6, thereby ensuring that the material is not stuck when loading and ensuring the overall quality of the sand.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
