[0001] This utility model relates to the field of rail vehicle manufacturing technology, and in particular to a sand-spreading funnel and sand-spreading device. Background Technology

[0002] Adding sand to the sand box of the sand spreading device at one end of the tram's head car is inconvenient. The inspection cover slightly obstructs the sand box's sand filling port, causing the gap in the sand filling port to narrow. Operators need to spend a lot of time slowly adding sand, and there is also a phenomenon of sand and gravel loss during the sand adding process.

[0003] To address the above issues, we designed a convenient and quick tool that can rapidly add sand to the sand box while preventing sand loss. Utility Model Content

[0004] The main purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a sand-spreading funnel and sand-spreading device. The angle between the funnel head and the sand discharge pipe can be adjusted by an adjustable component to avoid interference from the inspection cover plate, thereby improving the sand-spreading efficiency.

[0005] To achieve the purpose of this utility model, this utility model first provides a sand-spreading funnel, which adopts the following technical solution:

[0006] A sand-spraying funnel includes a funnel head and a sand-discharging pipe. The funnel head and the sand-discharging pipe are connected by an adjustable component that can adjust the relative angle between the funnel head and the sand-discharging pipe. The adjustable component is detachably connected to the funnel head and the sand-discharging pipe.

[0007] Furthermore, the adjustable component includes a deformable elastic sleeve, the two ends of which are connected to the funnel head and the sand discharge pipe, respectively.

[0008] Furthermore, the elastic sleeve is provided with internal threads, which are threadedly connected to the funnel head and the sand discharge pipe.

[0009] Furthermore, the adjustable component also includes a protective sleeve disposed at the connection between the funnel head and the adjustable component.

[0010] Furthermore, the bottom of the funnel head is provided with a connecting pipe with the same outer length diameter as the sand discharge pipe, and the protective sleeve is provided at the connection between the funnel head and the connecting pipe.

[0011] Furthermore, the protective sleeve includes a barrel-shaped side wall and a top wall, and the top wall is provided with a through hole for the connecting pipe to pass through.

[0012] Furthermore, the length of the sidewall is greater than or equal to the length of the connecting pipe.

[0013] Furthermore, the sand discharge pipe includes a threaded section and a tapered section, with one end of the threaded section connected to the adjustable component and the other end connected to the tapered section.

[0014] Furthermore, the funnel head is provided with a handle for holding and adjusting the direction.

[0015] The second objective of this invention is to provide a sand-spreading device, which adopts the following technical solution:

[0016] A sand spreading device includes a sand box, and a sand spreading funnel as described above is assembled and connected to the sand box.

[0017] In summary, the sand-spreading funnel and sand-spreading device provided by this utility model have the following technical advantages compared with the prior art:

[0018] 1. By adjusting the relative angle between the funnel head and the sand discharge pipe through the adjustable component, the assembly of the sand-spreading funnel can be avoided when the inspection cover plate on the top of the sand-spreading box is filled with sand.

[0027] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] This utility model first provides a sand-spreading funnel, including a funnel head 1 and a sand-discharging pipe 2. The funnel head 1 and the sand-discharging pipe 2 are connected by an adjustable component 3 that can adjust the relative angle between the funnel head 1 and the sand-discharging pipe 2. The adjustable component 3 is detachably connected to the funnel head 1 and the sand-discharging pipe 2.

[0033] like Figures 1 to 4 As shown, the sand-spreading funnel provided by this utility model includes a funnel head 1. In this embodiment, the funnel head 1 is a hollow conical structure, and a handle 11 is provided on the outside of the conical sidewall for holding the funnel head 1, thereby controlling the position of the funnel head 1 and preventing the funnel head 1 from deviating when sand is fed in without being fixed. The vertical angle of the funnel head 1 can also be adjusted by holding the handle 11.

[0034] The funnel head 1 has a large-diameter end as the sand inlet and a small-diameter end as the sand outlet. The sand outlet is connected to the sand discharge pipe 2. Furthermore, in this embodiment, the funnel head 1 is connected to the sand discharge pipe 2 via an adjustable component 3. Specifically, as shown... Figure 3 As shown, at the lower end of the funnel head 1, there is a connecting pipe 12 that communicates with the inside of the funnel head 1. One end of the adjustable component 3 is detachably connected to the connecting pipe 12, and the other end is detachably connected to the sand discharge pipe 2.

[0035] In this embodiment, the adjustable component 3 includes at least one elastic sleeve 31. The elastic sleeve 31 has a certain rigidity and can produce elastic deformation. When deformed, the side wall bends in an arc shape and does not produce sharp bends, so that sand and gravel will not get stuck in the elastic sleeve 31.

[0036] like Figure 3 and Figure 4 As shown, the elastic sleeve 31 has an internal thread, and the corresponding connecting pipe 12 has an external thread, allowing the elastic sleeve 31 to be threadedly connected to the connecting pipe 12. The sand discharge pipe 2 includes a threaded section and a tapered section. The outer diameter of the threaded section is the same as the outer diameter of the connecting pipe 12, so that the elastic sleeve 31 does not need to undergo diameter reduction processing inside. Furthermore, each sand-spreading funnel can be equipped with multiple elastic sleeves 31 of different lengths, and the appropriate length of elastic sleeve 31 can be selected according to the application scenario of the sand-spreading funnel.

[0037] Furthermore, there can be multiple elastic sleeves 31, which are threaded together. By connecting different numbers of elastic sleeves 31, adjustable components 3 of different lengths can be formed to suit different scenarios. When different numbers of elastic sleeves 31 are provided, each elastic sleeve 31 is threaded together through internal and external threaded ends. This is a conventional technique for threaded connections between identical components and will not be elaborated upon. Other connection methods can also be used without limitation, but all are within the scope of protection of this application.

[0038] Furthermore, the elastic sleeve 31 can be a straight pipe or a bent pipe with an arc section in the middle. When multiple elastic sleeves 31 are provided, they can be directly or indirectly connected by providing at least two elastic sleeves 31 with arc sections to adjust the longitudinal relative position and / or relative angle between the funnel head 1 and the sand discharge pipe 2.

[0039] A protective sleeve 13 is provided at the bottom of the funnel head 1. Preferably, the protective sleeve 13 is located at the connection between the funnel head 1 and the connecting pipe 12. The protective sleeve 13 includes a barrel-shaped side wall and a top wall, that is, the protective sleeve 13 is a barrel-shaped structure with an open bottom and a closed top. The top wall is provided with a through hole for the connecting pipe 12 to pass through, so that the protective sleeve 13 fits over the outside of the connection between the funnel head 1 and the connecting pipe 12.

[0040] The length of the side wall of the protective sleeve 13 is greater than or equal to the length of the connecting pipe 12. Preferably, the length of the protective sleeve 13 is greater than or equal to the length of the elastic sleeve 31. When the sand discharge funnel is assembled and connected to the sand spreading device, the protective sleeve 13 covers the through hole of the sand spreading device to prevent sand from leaking out from the funnel head 1 and getting stuck between the sand discharge pipe 2 and the through hole of the sand spreading device, or from flowing out of the through hole, thus preventing sand from being lost. Furthermore, the diameter of the top wall of the protective sleeve 13 is greater than or equal to the diameter of the through hole of the sand spreading device. The protective sleeve 13 can also protect the connection between the elastic sleeve 31 and the connecting pipe 12, preventing sand and dust from entering the threads of the connecting pipe 12 and wearing the internal threads of the elastic sleeve 31.

[0041] The sand discharge pipe 2 includes a threaded section and a tapered section. As mentioned earlier, the upper part of the threaded section is threadedly connected to the lower part of the elastic sleeve 31. The thread length is greater than the length of the elastic sleeve 31, allowing the sand discharge pipe 2 to be threadedly connected to the sand box or other sand and gravel containing structure, or mobile device (including but not limited to rail vehicles, sand discharge cars, etc.) with a sand discharge funnel clamping / fixing structure, and the insertion depth and angle can be adjusted. The tapered section is used to limit the outflow velocity of sand and gravel. Preferably, the tapered section and the threaded section are detachably connected, and different tapered sections can be replaced according to the sand spreading needs to control the outflow velocity of sand and gravel and achieve different sand spreading effects.

[0042] This utility model further provides a sand spreading device, including a sand box with a sand inlet. The sand discharge pipe 2 of the sand spreading funnel, as described above, is inserted into the sand inlet, thus assembling and connecting the sand spreading funnel with the sand box. Furthermore, the sand inlet is threaded, allowing the sand spreading funnel to be threadedly connected to the sand box. This provides the side wall of the sand box with a certain clamping and fixing effect on the sand spreading funnel, and the insertion depth of the sand discharge pipe 2 can be adjusted via the thread.

[0043] In use, the assembly method of the sand discharge funnel and the sand box can be selected according to the effective space at the top of the sand box. If there is sufficient space and no interference occurs, the sand discharge pipe 2 of the assembled sand discharge funnel can be directly inserted into the sand box through the sand inlet. If interference occurs, force is applied to cause the elastic sleeve 31 to elastically deform, allowing the sand discharge pipe 2 to be smoothly inserted into the sand box, depending on the degree of interference. If necessary, the sand discharge funnel can be disassembled, the sand discharge pipe 2 inserted into the sand box first, and then the elastic sleeve 31 and funnel head 1 sequentially connected to the sand box. The sand discharge pipe 2 is assembled and connected. When the interference is severe, the relative position and / or relative angle between the funnel head 1 and the sand discharge pipe 2 can be adjusted by using a multi-segment elastic sleeve 31 with an arc-shaped segment. Furthermore, the funnel head 1 can be held by the handle 11 to prevent it from moving when adding sand. The deformation of the elastic sleeve 31 can be adjusted by pulling or pushing the handle 11, thereby adjusting the angle of the funnel head 1 so that it is easier to add sand and improve the sand adding efficiency.

[0044] In the preceding text, the sand-spreading funnel of a rail vehicle sand-spreading device was used as an example to introduce the assembly method of the sand-spreading funnel and the sand box. In practical applications, the sand-spreading funnel can also be used directly for sand-spreading. A blocking structure to control the sand-spreading state is set at the end of the sand discharge pipe 2 or at any position of the sand discharge pipe 2. The operator holds the handle 11 and holds the sand-spreading funnel to perform sand-spreading operations. Alternatively, a clamping or other fixing device that can be fixed to the sand-spreading funnel assembly device can be set on the moving device. After the sand-spreading funnel is assembled and fixed to the moving device through the fixing device, the moving device drives the sand-spreading funnel to move. By holding the handle 11, the angle and orientation of the end of the sand discharge pipe 2 can be adjusted. Especially during the sand-spreading process, the handle 11 can be held at all times to ensure that the direction and angle of the sand discharge pipe 2 do not move. The moving device includes, but is not limited to, rail vehicles, sand-spreading trolleys with rollers, etc. The sand-spreading funnel and the moving device such as the rail vehicle can be detachably assembled and connected. It can be used alone or assembled with the moving device without requirements or restrictions.

[0045] In summary, the sand-spreading funnel and sand-spreading device provided by this utility model have the following technical advantages compared with the prior art:

[0046] 1. By adjusting the relative angle between the funnel head and the sand discharge pipe through the adjustable component, the assembly of the sand-spreading funnel can be avoided when the inspection cover plate on the top of the sand-spreading box is filled with sand. If necessary, the sand discharge pipe and the funnel head can be disassembled, the sand discharge pipe can be inserted into the sand box first, and then connected to the funnel head through the deformable elastic sleeve.

[0047] 2. An elastic sleeve is installed so that no sharp angle is generated during deformation, which will not affect the smooth sliding of sand and gravel;

[0048] 3. Adjust the position of the sand-sprinkling funnel by the handle to improve work efficiency;

[0049] This utility model provides a convenient, fast, and adjustable sand-spreading funnel and sand-spreading device, which meets the needs of the tram's head car end sand-spreading device sand box filling inconveniently, ensures that sand and gravel are added normally into the sand box during the sand-spreading process, and improves the work efficiency of the sand-spreading personnel.

[0050] As described above, similar technical solutions can be derived from the given solutions. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from the scope of this utility model's technical solution, shall still fall within the scope of this utility model's technical solution.
