Description

Technical Field

[0001] This utility model relates to the field of jig technology, specifically to a jig bed thickness detection device. Background Technology

[0002] A jig is a device that performs the jigging process. Materials are primarily separated based on density differences in a vertically moving, variable-speed medium flow. Differences in particle size and shape significantly impact the beneficiation results. In actual production, the jig feeds the raw materials to be separated onto a screen plate, forming a dense material layer called the bed. During production, the raw materials enter the machine, and the jig provides a reciprocating, pulsating water flow. Under this flow, the raw materials gradually separate. Repeatedly impacted by the pulsating water flow, the bed begins to loosen and separate, entering the water. Different substances within the raw materials exhibit different trajectories due to the water flow impact, resulting in relative movement and stratification. As the upward motion ends, the bed becomes denser. During periods of inactivity and downward movement, the bed is even denser, and stratification is more pronounced. Once all the raw material particles have completed their movement according to their density characteristics, the bed returns to its previous compact state. At this point, almost all particles no longer exhibit relative movement, thus essentially completing the separation process. The high-density ore that sinks to the bottom of the screen plate and has a certain thickness is usually called the bed. The height of the bed plate extending upwards from the screen plate is called the bed thickness. If the bed is too thick, it is difficult for the rising water flow to disperse it, reducing the sorting efficiency. Minerals with a lower specific gravity may also remain in the bed, affecting the sorting results. Therefore, it is necessary to detect the bed thickness in a timely manner. When the bed reaches a certain thickness, the discharge system should be activated to discharge the material to control the bed thickness. Currently, measurement and calibration are performed manually using measuring tools such as rulers, which requires multiple measurements, and the reading process is inconvenient and has low accuracy.

Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0025] Example 1:

[0026] Reference Figures 1 to 5 This utility model provides a jig machine layer thickness detection device, comprising:

[0027] Mounting frame 1 is composed of an inner side plate 11, a connecting plate 12 and an outer side plate 13 connected in a U-shape. The outer side plate 13 is provided with a fastening component 2 for mounting the mounting frame 1 on the jig.

[0028] The movable rod 3 is movably mounted on the outer side plate 13. The outer side plate 13 is provided with a scale 131, and the movable rod 3 is provided with a measuring pointer 31.

[0029] The float 4 and the moving rod 3 are each provided with several connecting rods 5 that can be detached and spliced ​​at both ends. A crossbar 6 is detachably installed at the connecting rod 5 at the top of the float 4. The crossbar 6 is detachably connected to the connecting rod 5 at the top of the moving rod 3.

[0030] Marker block 7 is movably mounted on outer side plate 13. Marker block 7 is provided with calibration pointer 71 and limit component 8 for adjusting the position of marker block 7.

[0031] In use, the mounting bracket 1 is detachably installed on the jig by fastening component 2. Utilizing the detachable structure of several connecting rods 5, different numbers of connecting rods 5 can be spliced ​​together as needed to adjust the connection length between the float 4 and the moving rod 3, thus adapting to jigs of different specifications and exhibiting good versatility. The initial or maximum bed thickness of the jig can be calibrated by the limiting component 8 in conjunction with the calibration pointer 71 on the marking block 7. The bed thickness can be automatically measured at any time by the measuring pointer 31 on the float 4 and the moving rod 3, and the reading can be directly taken from the outer side plate 13 located on the outside of the jig, effectively avoiding human measurement errors, improving measurement accuracy, and facilitating the comparison of the bed thickness calibrated by the calibration pointer 71 at any time, providing convenience for bed thickness measurement. Furthermore, the working state of the jig can be adjusted or the jig can be cleaned based on this comparison information to maintain the normal operation of the jig.

[0032] Specifically, the fastening assembly 2 includes a threaded rod 21 and a pressure block 22. The outer side plate 13 is provided with a threaded hole for threaded installation of the threaded rod 21. The pressure block 22 is provided at one end of the threaded rod 21, and the other end of the threaded rod 21 is provided with a handle 211. The pressure block 22 is used to cooperate with the inner side plate 11 to clamp onto the jig.

[0033] Rotating the handle 211 drives the threaded rod 21 to rotate. During the rotation of the threaded rod 21, it engages with the threaded hole on the outer side plate 13 to drive the pressure block 22 to move closer to the inner side plate 11. The pressure block 22, in conjunction with the inner side plate 11, clamps onto the side wall of the jig, thus enabling the detachable installation of the mounting frame 1.

[0034] Specifically, one end of the connecting rod 5 is provided with a connecting screw hole 51 and the other end is provided with a connecting screw 52 that is threaded into the connecting screw hole 51. The moving rod 3 and the float 4 are both provided with mounting screws 9 that are threaded into the connecting screw hole 51. Both ends of the crossbar 6 are rotatably provided with threaded sleeves 61 that are threaded into the connecting screw 52.

[0035] The aforementioned detachable structure allows for the selection of different numbers of connecting rods 5 to adjust the connection length between the float 4 and the moving rod 3, thus adapting to different specifications of jigs and exhibiting good versatility.

[0036] Example 2:

[0037] Reference Figures 1 to 5 In conjunction with the technical solution of Embodiment 1, in this embodiment, the limiting component 8 includes a magnet 8 and an adjusting block 82. The adjusting block 82 is movably mounted on the marking block 7, the magnet 8 is disposed on the adjusting block 82, and an iron sheet 132 is disposed on the outer side plate 13. The magnet 8 and the iron sheet 132 attract each other to drive the adjusting block 82 to press against the iron sheet 132.

[0038] When the position of the marker block 7 needs to be adjusted, manually move the adjusting block 82 to drive the magnet 8 away from the iron plate 132, then move the marker block 7 to the designated position. After the external force is removed, the magnet 8 is firmly attracted to the iron plate 132 again, and the adjusting block 82 is reset. At this time, the marker block 7 is not easy to move under non-human force, thus realizing the position adjustment of the marker block 7.

[0039] Specifically, the adjusting block 82 is provided with a rubber pad 821 that abuts against the iron sheet 132.

[0040] By setting a rubber pad 821 on the adjusting block 82, the friction between the adjusting block 82 and the iron sheet 132 is increased, making the marker block 7 less likely to move under non-human force, which is beneficial for the position adjustment of the marker block 7.

[0041] Specifically, the adjusting block 82 is equipped with a pull ring 822.

[0042] By providing a pull ring 822 on the adjusting block 82, it is convenient to manually pull the adjusting block 82 to move it, which facilitates the position adjustment operation of the marking block 7.

[0043] Specifically, the inner side plate 11 is provided with a limiting cylinder 111 through which the connecting rod 5 moves.

[0044] By setting a limiting cylinder 111 on the inner side plate 11 for the connecting rod 5 to move through, the movement of the connecting rod 5 at the float 4 is limited, so that the float 4 can drive the moving rod 3 to move up and down more smoothly, which helps to improve the accuracy of bed thickness measurement.

[0045] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
