Description

Technical Field

[0001] This utility model relates to the field of briquette sample preparation technology, and in particular to a briquette sample preparation machine. Background Technology

[0002] As is well known, coal samples are used to understand the physical, chemical, and technological properties of coal, in order to test briquette binders and determine the thermal and cold strength of briquettes. Existing briquette sample making machines include a base, a briquette cylinder, and a hydraulic cylinder. In use, the briquette cylinder is placed on the base, and the unformed coal sample is placed inside. The hydraulic cylinder then presses the sample to form it within the cylinder. Afterward, the cylinder rod returns to its original position and the sample is removed from the briquette cylinder. The pressed briquette sample needs to be manually tapped out of the cylinder and sent for testing. Although the above-mentioned briquette sample making machine has a simple structure, it cannot achieve the natural removal of the briquette sample during the pressing process. Furthermore, the briquette is not completely removed during the removal process, and some remains inside the briquette cylinder. The inner wall of the briquette cylinder needs to be cleaned; otherwise, it will affect the test results in subsequent uses. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model discloses a briquette sample making machine.

[0004] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0005] A briquette sample making machine includes a frame, a base, and a briquette cylinder. The base is fixed to the lower bottom plate of the frame, and the briquette cylinder is provided on the upper part of the base. A connecting piece A is fixed to the outside of the briquette cylinder. The two ends of the connecting piece A are respectively fixedly connected to cylinders A fixed on the two side walls of the frame. Cylinders B, corresponding to the upper and lower parts of the briquette cylinder, are fixed on the upper bottom plate of the frame. The connecting piece A includes a fixing ring A and connecting rods A fixed on both sides of the fixing ring A. The fixing ring A is fixed to the outside of the briquette cylinder, and connecting rings extend from the outer ends of the connecting rods A. The connecting rings are respectively fixedly connected to the telescopic shafts of cylinders A.

[0006] The briquette sample making machine has corresponding square grooves on both sides of the inner wall of the frame, and the base of cylinder A is fixed on the bottom surface of the groove.

[0007] A briquette sample making machine includes a frame, a base, and a briquette cylinder. The base is fixed to the lower bottom plate of the frame, and the briquette cylinder is located on the upper part of the base. A connector B is fixed to the outside of the briquette cylinder, and the two ends of the connector B are slidably mounted on slide bars on the side walls of the frame. Cylinders B, corresponding to the upper and lower parts of the briquette cylinder, are fixed to the upper bottom plate of the frame. The connector B includes a connecting rod B and a fixing ring B. The fixing ring B is fixed to the outside of the briquette cylinder, and connecting rods B are fixed to the outside of both sides of the fixing ring B.

[0008] The briquette sample making machine has T-shaped slide bars, which are vertically fixed on the inner walls of both sides of the frame.

[0009] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0010] The briquette sample making machine of this utility model uses cylinders B or slide bars on both sides of the frame, and connecting parts A or B to drive the briquette cylinder upward, so as to achieve the purpose of automatic separation of the briquette cylinder from the briquette when pressing the briquette. This utility model has a simple structure and is easy to use.

[0014] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0015] Combined with appendix Figure 1The briquette sample making machine includes a frame 1, a base 5, and a briquette cylinder 7. The base 5 is fixed to the lower bottom plate of the frame 1, and the briquette cylinder 7 is located on the upper part of the base 5. A connector A is fixed to the outside of the briquette cylinder 7. The two ends of the connector A are respectively fixedly connected to cylinders A4 fixed to the two side walls of the frame 1. Corresponding square grooves 2 are opened on the inner walls of both sides of the frame 1. The base of the cylinder A4 is fixed to the bottom surface of the groove 2. A cylinder B8 corresponding to the upper and lower parts of the briquette cylinder 7 is fixed on the upper bottom plate of the frame 1. The connector A includes a fixing ring A6 and connecting rods A3 fixed on both sides of the fixing ring A6. The fixing ring A6 is fixed to the outside of the briquette cylinder 7. A connecting ring extends from the outer end of the connecting rod A3. The connecting ring is fixedly connected to the telescopic shaft of the cylinder A4.

[0016] During use, the worker places the irregular coal sample into the coal forming cylinder 7. The telescopic shaft of cylinder B8 extends downward and presses into the coal forming cylinder 7. According to the set pressure, the irregular coal sample is pressed into shaped coal. At this time, the telescopic shaft of cylinder A4, located in groove 2, extends upward, driving the connecting rod A3 and the fixing ring A6 to move the coal forming cylinder 7 upward. The coal forming cylinder 7 gradually moves to the outside of the telescopic shaft of cylinder B8, so that the coal forming cylinder 7 is completely separated from the shaped coal. Finally, the telescopic shaft of cylinder B8 retracts to its original position, and the worker takes out the shaped coal. Cylinder A4 drives the connecting rod A3 and the fixing ring A6 to return the coal forming cylinder 7 to its original position for easy use next time.

[0017] Combined with appendix Figure 2 The briquette sample making machine includes a frame 1, a base 5, and a briquette cylinder 7. The base 5 is fixed to the lower bottom plate of the frame 1, and the briquette cylinder 7 is located on the upper part of the base 5. A connector B is fixed to the outside of the briquette cylinder 7. The two ends of the connector B are slidably mounted on slide bars 9 on the two side walls of the frame 1. The slide bars 9 are T-shaped slide bars and are vertically fixed to the inner side walls of the frame 1. A cylinder B8 corresponding to the upper and lower parts of the briquette cylinder 7 is fixed on the upper bottom plate of the frame 1. The connector B includes a connecting rod B11 and a fixing ring B12. The fixing ring B12 is fixed to the outside of the briquette cylinder 7. A connecting rod B11 is fixed to the outside of both sides of the fixing ring B12. A U-shaped slider 10 extends from the outer end of the connecting rod B11 and is slidably mounted on the slide bar 9. A cylinder C13 is fixed to both sides of the upper part of the base 5. The telescopic shafts of the cylinder C13 are fixedly connected to the lower sides of the fixing ring B12.

[0018] During use, the worker places the irregular coal sample into the coal forming cylinder 7. The telescopic shaft of cylinder B8 extends downward and presses into the coal forming cylinder 7. According to the set pressure, the irregular coal sample is pressed into shaped coal. At this time, the cylinders C13 located on both sides of the base 5 lift the fixing ring B12 upward, thereby driving the coal forming cylinder 7 to move upward. At the same time, the connecting rod B11 and the slider 10 at the outer end move along the slide bar 9, ensuring the straightness of the upward movement of the coal forming cylinder 7. The coal forming cylinder 7 gradually moves to the outside of the telescopic shaft of cylinder B8, so that the coal forming cylinder 7 is completely separated from the shaped coal. Finally, the telescopic shaft of cylinder B8 retracts to its original position, and the worker takes out the shaped coal. Cylinder C13 drives the fixing ring B12, connecting rod B11 and slider 10 to move downward along the slide bar 9, so that the coal forming cylinder 7 returns to its original position for the next use.
