Description

Technical Field

[0001] The utility model belongs to the technical field of coal sampling, and specifically relates to a coal sampling shovel. Background Art

[0002] Coal is a solid combustible mineral formed by the complex biochemical and physicochemical changes of ancient plants buried underground. Coal is hailed as black gold and the food of industry, and it has been one of the main energy sources used by the human world since the 18th century.

[0003] In order to ensure the quality of the produced coal, sampling and detection are required in multiple links during the coal production process. However, the current sampling shovel used for sampling has a simple structure and is generally only composed of a bucket and a handle. There are certain deficiencies in the process of collecting coal samples and it cannot meet the usage requirements. For example, when encountering a relatively hard coal seam during use, it is difficult to insert the bucket into the coal to complete the sampling. Secondly, the quantity of the sample needs to be controlled during sampling. The current bucket cannot quantitatively collect coal, so manual weighing and measurement of the coal sample are still required later, which affects the work efficiency. Therefore, in view of the above technical problems, it is necessary to provide a coal sampling shovel. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a coal sampling shovel, which can solve the above problems.

[0005] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0006] A coal sampling shovel includes a bucket. A fixed block is fixedly connected inside the bucket. A storage groove is opened on the fixed block. A sleeve is fixedly connected to the bucket.

[0026] In order to enable those skilled in the art of this technology to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1 to 6 shown, a coal sampling shovel in an embodiment of the present utility model includes a bucket 1. The provided bucket 1 can be used to dig coal for sampling. A sleeve 3 is fixedly connected to the bucket 1. The sleeve 3 is the handle of the sampling shovel, and holding the sleeve 3 is convenient for using the sampling shovel. A through hole 2 communicating with the sleeve 3 is opened on the bucket 1. A movable rod 19 is movably installed inside the sleeve 3. One end of the movable rod 19 passes through the through hole 2 and is fixedly connected to a push plate 17. A plurality of insert rods 18 are fixedly connected to the push plate 17. The movable rod 19 can move inside the sleeve 3 and the through hole 2. When it is impossible to complete the material taking due to encountering a hard coal seam, the movable rod 19 can be pushed to drive the push plate 17 and the insert rods 18 to move, smashing the hard coal seam to make it loose so as to complete the material taking.

[0028] Inside the bucket 1, a fixed block 7 is fixedly connected. A storage groove 8 is provided on the fixed block 7. The coal dug can enter the inside of the storage groove 8 within the bucket 1. The push plate 17 is located above the fixed block 7 inside the bucket 1. The lower end surface of the push plate 17 is in contact with the upper end surface of the fixed block 7. During the process of pushing the push plate 17, or after digging coal and then pushing the push plate 17, the coal overflowing from the storage groove 8 can be scraped flat by the push plate 17, so that only a certain amount of coal can be stored in the storage groove 8.

[0029] As Figure 4 shown, one side of the fixed block 7 close to the opening of the bucket 1 is set as a slope, which can prevent the fixed block 7 from obstructing the movement of the coal, so that the coal in the bucket 1 can better enter the storage groove 8 above the fixed block 7.

[0030] An installation groove 9 is provided on the inner wall of the storage groove 8. An adjusting plate 10 is movably installed inside the storage groove 8. A convex block 11 matching the installation groove 9 is connected to the side wall of the adjusting plate 10. A first threaded hole 12 is provided on the convex block 11. An adjusting bolt 13 is threadedly connected inside the first threaded hole 12. The bottom end of the adjusting bolt 13 is rotatably connected to the bucket 1. Rotating the adjusting bolt 13 can drive the adjusting plate 10 to move up and down, so as to adjust the internal capacity of the storage groove 8, thereby meeting the sampling requirements of different quantities. A scale 16 is fixedly connected inside the storage groove 8, which can more intuitively view the internal capacity condition of the storage groove 8 and is convenient for adjustment operations.

[0031] As Figure 4 and Figure 5 shown, a plurality of first sliding strips 15 are fixedly connected inside the storage groove 8. A plurality of first grooves 14 matching the first sliding strips 15 are provided on the side wall of the adjusting plate 10. The first sliding strips 15 and the first grooves 14 can play a limiting role on the adjusting plate 10, making its use more stable and reliable.

[0032] As Figure 1 and Figure 3 shown, a second threaded hole 4 is provided on the sleeve 3. A fixing bolt 5 is threadedly connected inside the second threaded hole 4. The bottom end of the fixing bolt 5 is in contact with the surface of the movable rod 19. Tightening the fixing bolt 5 can fix the movable rod 19 for convenient daily use.

[0033] The other end of the movable rod 19 passes through the sleeve 3 and is provided with an installation notch 20. A push rod 21 is rotatably connected inside the installation notch 20. The length of the push rod 21 from the connection part to one end is less than the depth of the installation notch 20. The push rod 21 is located outside the bucket 1. By using the push rod 21, the movable rod 19 can be conveniently operated, and the movable rod 19 can be pushed more forcefully to move and break the coal seam. At the same time, the push rod 21 can be rotated into the installation notch 20 and kept in the same direction as the movable rod 19 for disassembly.

[0034] As Figure 2 and Figure 6 shown, two second sliding strips 23 are fixedly connected to the inner wall of the bucket 1. Two second grooves 22 matching the second sliding strips 23 are formed in the side wall of the push plate 17. The push plate 17 can move along them through the second sliding strips 23 and the second grooves 22, making the use of the push plate 17 smoother.

[0035] A toothed plate 6 is fixedly connected to the bucket 1. The toothed plate 6 is located at the opening of the bucket 1. By inserting the toothed plate 6 into the coal seam, the bucket 1 can be stabilized, preventing the bucket 1 from sliding during excavation and improving the performance of the bucket 1.

[0036] During use, the collection shovel can be picked up by using the sleeve 3, and the bucket 1 can be inserted into the coal seam to be sampled. After insertion, the coal enters the inside of the bucket 1 from the opening of the bucket 1 and can also enter the storage groove 8 on the fixed block 7. Then, the push plate 17 is pushed. The movement of the push plate 17 can push out and level the coal overflowing from the storage groove 8, so that a fixed amount of coal samples can be stored in the storage groove 8 for subsequent use. At the same time, if a relatively hard coal seam is encountered during coal mining and the bucket 1 cannot take materials, the push plate 17 can be pushed multiple times. The insertion rod 18 on the push plate 17 can break the coal seam to make it loose, and then sampling can be carried out.
