Description

Technical Field

[0001] This utility model relates to the technical field of sampling in coal conveying systems, specifically a sampling shovel for coal conveying systems. Background Technology

[0002] A Chinese patent has been granted, disclosing a labor-saving coke sampling shovel (authorization announcement number: CN217687947U), comprising: a shovel body, a connecting rod, and a handle; the front end of the shovel body is open, and the two sides and rear end are provided with side panels; the first end of the connecting rod is fixedly connected to the rear end panel of the shovel body, and the tail end of the connecting rod is fixedly connected to the handle; a vibration device is fixedly installed on the outer side of the rear end panel. The switch button of the vibration device is located at the handle. The front end of the shovel plate of the shovel body is pointed. The thickness of the rear end panel of the shovel body is greater than that of the two side panels. This utility model provides a vibration device at the rear end panel of the shovel body, and the switch of the vibration device is located at the handle.

[0003] Although the vibration device allows the sampling shovel to be easily inserted into the sample pile when shoveling material, it is still necessary to manually lift the sampling shovel after shoveling, and during the lifting process, the other hand needs to be used as a support point, which is quite strenuous. Utility Model Content

[0004] The purpose of this invention is to provide a sampling shovel for a coal conveying system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sampling shovel for a coal conveying system includes a support frame and a sampling shovel. The sampling shovel includes a handle and a sampling bucket connected to the handle. A support base is mounted on the support frame and is capable of rotating and swinging relative to the support frame.

[0007] A through groove is formed on the support base, and the handle passes through the through groove and rolls into contact with the pulley assembly disposed in the through groove.

[0008] The sampling shovel for the coal conveying system described above: a turntable is rotatably mounted on the support frame, and the turntable is connected to the support base via a hinge.

[0009] The sampling shovel for the coal conveying system described above: the hinge includes a connecting seat fixed on the support base, and the connecting seat is rotatably connected to the turntable via a connecting shaft.

[0010] The sampling shovel used in the coal conveying system described above: the support base is a cuboid structure with open ends.

[0011] The sampling shovel for the coal conveying system described above: the pulley block includes two rows of symmetrically arranged pulleys, and the handle passes through the gap between the two rows of pulleys and makes rolling contact with the pulleys.

[0012] The sampling shovel used in the coal conveying system described above: the support frame is a telescopic support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: after the handle passes through the support base, it can rotate and swing up and down relative to the support frame, and can also move along the axial direction of the handle itself relative to the support base, which effectively improves the convenience of use. At the same time, the pulley group set in the support base can reduce the friction force obtained by the handle moving along its own axial direction, which effectively reduces the labor intensity of workers sampling.

[0019] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0020] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0021] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0022] This utility model aims to provide a sampling shovel, specifically applied in a coal conveying system, to provide workers with corresponding support when using the sampling shovel, while eliminating the corresponding limiting forces on the sampling shovel and improving the convenience of sampling. The specific implementation method is as follows:

[0023] Please see Figures 1-4 In this embodiment of the present invention, a sampling shovel for a coal conveying system includes a support frame 1 and a sampling shovel. The sampling shovel includes a handle 5 and a sampling bucket 6 connected to the handle 5. A support base 4 is mounted on the support frame 1 and is rotatable and swingable relative to the support frame 1. A through groove is formed on the support base 4. The handle 5 passes through the through groove and rolls in contact with a pulley group 8 disposed in the through groove.

[0024] In this embodiment, after the handle 5 passes through the support base 4, it can rotate and swing up and down relative to the support frame 1. At the same time, it can also move along the axial direction of the handle 5 relative to the support base 4, which effectively improves the ease of use. Meanwhile, the pulley group 8 provided in the support base 4 can reduce the friction force generated by the handle 5 moving along its own axial direction, which effectively reduces the labor intensity of workers sampling.

[0025] Furthermore, a turntable 2 is rotatably mounted on the support frame 1, and the turntable 2 is connected to the support base 4 through a hinge, wherein the hinge includes a connecting seat 7 fixed on the support base 4, and the connecting seat 7 is rotatably connected to the turntable 2 through a connecting shaft 3.

[0026] The turntable 2 described above has a rotating shaft installed at its bottom. The rotating shaft is inserted into the support frame 1, thereby enabling the turntable 2 to rotate relative to the support frame 1. The connecting seat 7 and the connecting shaft 3 effectively enable the support seat 4 to swing relative to the support frame 1 and the turntable 2.

[0027] For example, in one embodiment, the support base 4 is arranged in the form of a cuboid structure with open ends, the pulley group 8 includes two rows of symmetrically arranged pulleys, the handle 5 passes through the gap between the two rows of pulleys and rolls in contact with the pulleys, thereby eliminating the problem of large friction when the handle 5 directly contacts the support base 4, and achieving the effect of saving effort.

[0028] Preferably, the support frame 1 is a telescopic support frame. In one embodiment, the telescopic support frame includes a support sleeve and a movable support rod. The turntable 2 is rotatably mounted on one end of the movable support rod, and the other end of the movable support rod is inserted into the support sleeve. The support sleeve is threaded with a bolt that can be inserted into it. The movable support rod is provided with multiple threaded holes. When the movable support rod moves to the desired position, the bolt is rotated so that the bolt is threadedly connected to the threaded hole at the current position, thereby fixing the position of the movable support rod and meeting the height adjustment needs of different users.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
