Description

Technical Field

[0001] The utility model relates to the technical field of cuttings grinding, in particular to a mortar for grinding cuttings. Background Art

[0002] During the exploration and construction of oil and natural gas, cuttings are intuitive materials for understanding formation lithology and hydrocarbon reservoirs. After grinding the cuttings into powder, research can obtain the mass or volume percentage of the cuttings sample and determine the rock type at the sampling depth. Combining with other data, a downhole cuttings stratigraphic profile can be made to intuitively understand the formation structure.

[0003] Existing tools for grinding cuttings are usually wide-mouth mortars. During use, the cuttings need to be pressed firmly and rotated simultaneously. During the pressing and rotating process, the cuttings are fully ground to form powder for the next step of research.

[0004] Although this grinding method can effectively grind solid granular cuttings into powder, during the grinding process, due to the force applied by the pestle handle, the cuttings are likely to splash out of the mortar body. In this case, new cuttings need to be collected again for supplementation to meet the quality and quantity requirements. In addition, the splashed cuttings are likely to cause physical harm to the staff near the mortar. At the same time, since the moving space of the cuttings in the wide-mouth mortar is large, the grinding efficiency is low. Moreover, since there is a direct force transmission between the pestle handle and the mortar, when the force applied by the pestle handle is too large, the mortar is likely to be damaged, reducing its service life.

[0005] Therefore, avoiding cuttings splashing, improving grinding efficiency, and increasing the service life of the mortar are technical problems that urgently need to be solved in the current field. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to better understand the purpose, structure and function of the present utility model, the mortar of the present utility model will be further described in detail below with reference to the drawings.

[0028] As Figure 1As shown, an embodiment of the present utility model provides a mortar 100 for grinding rock cuttings, including a mortar body 1, and the mortar body 1 can be any hollow shell that is convenient for accommodating rock cuttings. In the illustrated embodiment, the mortar body 1 includes a bottom wall and a side wall extending upward along the edge of the bottom wall, and the side wall encloses an opening shape with a cavity 12. Among them, a grinding assembly 2 is arranged in the cavity 12, and the shape of the grinding assembly 2 is adapted to the cavity 12. Thus, the grinding assembly 2 can move along the inner wall of the mortar body 1 in the cavity 12 to apply a force to the rock cuttings accommodated inside the cavity 12 until the rock cuttings are ground into a suitable form.

[0029] In this embodiment, a pressure relief hole 11 communicating with the cavity 12 is provided on the side wall of the mortar body 1. The pressure relief hole 11 is used to release the gas generated in the cavity 12 during grinding, avoiding the formation of a vacuum in the cavity 12 and hindering the movement of the grinding assembly 2.

[0030] As Figure 1 shown, the grinding assembly 2 includes a pestle 21, and the shape of the pestle 21 is configured to be adapted to the cavity 12. The pestle 21 can move repeatedly along the side wall formed by the cavity 12 to repeatedly grind the rock cuttings accommodated in the cavity 12.

[0031] According to a preferred embodiment of the present utility model, a wrenching cap 22 is provided at the upper end of the pestle 21, and the wrenching cap 22 is used to generate a fulcrum for the force on the pestle 21. A screwing cap 23 is sleeved above the wrenching cap 22, and a square rod shaft 231 is fixedly arranged on the surface of the screwing cap 23, and the square rod shaft 231 can be connected to a power source (not shown in the figure). The wrenching cap 22 and the screwing cap 23 are adapted in shape. In this embodiment, they are both regular polygon structures. Through the mutually cooperating screwing cap 23 and wrenching cap 22, the force can be transmitted to the screwing cap 23 through the square rod shaft 231, and the force can effectively reach the wrenching cap 22 through the screwing cap 23, thereby driving the pestle 21 to move in the cavity 12. In this way, the rock cuttings accommodated in the cavity 12 can be smoothly ground.

[0032] According to a preferred embodiment of the present utility model, as Figure 1 shown, fixing holes are provided at corresponding positions of the wrenching cap 22 and the screwing cap 23, and a fixing rod 24 is inserted into the fixing holes. By inserting the fixing rod 24 between the wrenching cap 22 and the screwing cap 23, the cooperation between the screwing cap 23 and the wrenching cap 22 becomes more firm, and thus the force transmission becomes more stable.

[0033] In one embodiment, the fixing rod 24 is located at a position outside the screwing cap 23, and a pin hole is correspondingly provided. A pin shaft is arranged in the pin hole, and the fixing rod 24 is radially limited by the pin shaft. Through this limiting method, the purpose of stably connecting the bearing screwing cap 22 and the screwing cap 23 is achieved.

[0034] In one embodiment, during use, the bearing screwing cap 22 located on the pestle 21 is connected to the screwing cap 23, and the fixing rod 24 is inserted into a fixing hole formed on the surfaces of the bearing screwing cap 22 and the screwing cap 23, and further fixed by using a pin shaft. In this way, a stable connection is formed among the screwing cap 23, the bearing screwing cap 22, and the pestle 21.

[0035] In one embodiment, the square rod shaft 231 provided on the surface of the screwing cap 23 is connected to a power source (not shown in the figure), and the acting force output by the power source is transmitted to the pestle 21 through the square rod shaft 231, the screwing cap 23, and the bearing screwing cap 22, thereby driving the pestle 21 to move in the same frequency as the power source.

[0036] Meanwhile, the rock cuttings to be processed are placed in the cavity 12 formed by the mortar body 1, and the pestle 21 is placed in the cavity 12. Since the shape of the pestle 21 is adapted to that of the cavity 12, the pestle 21 can move synchronously with the power source in the cavity 12 and continuously grind the rock cuttings accommodated in the cavity 12 for multiple times until the rock cuttings are ground into a suitable form.

[0037] In the illustrated embodiment, during the grinding of the rock cuttings, the gas generated by the grinding can be discharged from the pressure relief hole 11, avoiding the formation of a vacuum in the cavity 12 and bringing a reaction force to the grinding assembly 2, which affects the grinding efficiency. By setting the pestle 21 adapted to the cavity 14 for grinding, the technical problems in the prior art that the rock cuttings have a large movement space in the mortar, low grinding efficiency, and the rock cuttings are easy to splash and injure people are solved, and the technical effects of small movement space of the rock cuttings, high grinding efficiency, and avoiding the splash of the rock cuttings are achieved.

[0038] In one embodiment, a buffer assembly 3 is sleeved under the mortar body 1, and the buffer assembly 3 is used to buffer the acting force generated when the mortar body 1 is in use.

[0039] As Figure 1 shown, the buffer assembly 3 includes a seat plate 31 provided under the mortar body 1 for accommodating the grinding body, and a spring 32 arranged around the inner wall of the seat plate 31. The spring 32 is used to bear the mortar body 1 and buffer the acting force received by the mortar body 1 during grinding.

[0040] According to a preferred embodiment of the present utility model, a shock-absorbing disc 33 is provided above the spring 32. The mortar body 1 is carried above the shock-absorbing disc 33, such that the mortar body 1 is in contact with the shock-absorbing disc 33. By this arrangement, the contact area between the mortar body 1 and the buffer assembly 3 is increased, further providing a buffering effect on the grinding force. Therefore, by providing the buffer assembly 3, the force applied to the mortar body 1 can be buffered continuously and stably, avoiding the direct transmission of the force, reducing the wear of the mortar 100, and improving the service life.

[0041] According to a preferred embodiment of the present utility model, as Figure 3 shown, a plurality of hollow positioning holes 15 are provided at a position near the lower end of the outer surface of the mortar body 1, and a plurality of positioning protrusions 34 extending upward are provided on the bottom wall of the seat plate 31. The positions of the plurality of positioning holes 15 correspond to the plurality of positioning protrusions 34, such that when the mortar body 1 is placed in the seat plate 31, each of the positioning protrusions 34 can be inserted into a corresponding positioning hole 15. In this way, stable connection can be achieved, avoiding relative rotation between the mortar body 1 and the seat plate 31 when the mortar body 1 is subjected to a force and reducing the grinding efficiency. In this embodiment, both the positioning holes 15 and the positioning protrusions 34 are three, and are respectively arranged circumferentially and uniformly at a position near the lower end of the outer surface of the mortar body 1 and the bottom wall of the seat plate 31.

[0042] According to a preferred embodiment of the present utility model, as Figure 1 shown, a pouring spout 13 extending outward is provided at the top of the mortar body 1. The pouring spout 13 provides a guiding function when pouring the cuttings out of the mortar body 1, avoiding the spread of the cuttings.

[0043] According to a preferred embodiment of the present utility model, as Figure 1 shown, end ears 16 are provided on the outer wall of the mortar body 1. In the illustrated embodiment, there are two end ears 16, which are provided at a position near the upper end on the outer surface of the mortar body 1, and are used to provide a fulcrum for easily holding the mortar 100 for grinding cuttings.

[0044] According to a preferred embodiment of the present utility model, as Figure 1 shown, a detachable chassis 4 is provided below the seat plate 31, and a fixing member 35 formed by extending outward is provided on the outer surface of the seat plate 31. As Figure 2As shown, through holes 351 are formed on the surface of the fixing member 35, and threaded holes 41 are formed at positions corresponding to the through holes 351 on the chassis 4. In this embodiment, a bolt 36 passes through the through hole 351 and is connected to the threaded hole 41. In this way, the connecting seat plate 31 and the chassis 4 are fixedly connected, thereby providing a larger stress area for the mortar 100 for grinding rock chips, making the mortar body 1 more stable when grinding rock chips and improving the grinding efficiency. In this embodiment, the through holes 351 and the threaded holes 41 are three respectively, and are evenly distributed on the outer side of the seat plate 31 and the surface of the chassis 4.

[0045] According to the present invention, in use, first, the connecting seat plate 31 and the chassis 4 are fixedly connected by bolts 36.

[0046] Secondly, the mortar body 1 is placed in the seat plate 31, and a plurality of positioning protrusions 34 formed on the surface of the seat plate 31 are inserted into a plurality of positioning holes 15 below the mortar body 1, so as to prevent relative movement between the mortar body 1 and the seat plate 31.

[0047] Thirdly, the rock chips to be ground are placed in the cavity 12, and at the same time, the grinding assembly 2 is placed in the cavity 12.

[0048] In one embodiment, the torque receiving cap 22 and the screwing cap 23 are connected in sequence, and the square rod shaft 231 provided on the surface of the screwing cap 23 is connected to a power source (not shown in the figure). At this time, the acting force output by the power source is transmitted to the pestle 21 through the square rod shaft 231, the screwing cap 23, and the torque receiving cap 22, thereby driving the pestle 21 to move synchronously with the power source to repeatedly grind the rock chips accommodated in the cavity 12 until the rock chips are ground into a suitable form.

[0049] In one embodiment, during the grinding process, since the mortar body 1 is in contact with the shock-absorbing disc 33 and a spring 32 is provided below the shock-absorbing disc 33, the acting force received by the mortar body 1 can be transmitted to the spring 32 through the shock-absorbing disc 33 to buffer the acting force received by the mortar body 1.
