TECHNICAL FIELD

[0001] The utility model relates to the field of drilling construction technology, specifically relates to a special mixing hopper of drilling machine. BACKGROUND

[0002] The statements herein only provide the background of the utility model related, and do not necessarily constitute the prior art.

[0003] In the drilling construction process (mud wall hole forming), if the potassium salt stratum is encountered, serious slurry leakage problem will appear, and serious slurry leakage will make the upper part of the drilling hole loose stratum collapse and hold the drill, resulting in the stagnation of drilling construction, in order to ensure the safe and smooth construction of the drilling hole, high viscosity mixed slurry or cement mixed slurry is needed to be used to pre-fill and reinforce the lower part of the drilling hole leakage stratum, so as to ensure the smooth construction of the drilling hole.

[0004] The previous method is to directly add slurry materials such as anti-collapse agent, lignite and cement into the slurry pool, and realize the configuration of the drilling hole plugging slurry through manual stirring. However, if drilling construction is carried out during the rainstorm season, the slurry materials and cement materials need to be fully and quickly mixed in a short time, and the traditional method needs a long time and has the problems of uneven stirring, insufficient mixing with slurry and even accumulation of slurry materials at the bottom of the slurry pool.

[0005] Therefore, in order to make the slurry materials and the slurry fully and quickly mixed in a short time and improve the effect of drilling hole plugging in the potassium salt stratum, a specific slurry mixing device needs to be developed for innovative and effective application.

[0009] Further, a weighing component is arranged on the supporting platform and is used for weighing the materials placed on the supporting platform.

[0023] The utility model will be made further detailed explanation in combination with the drawings and examples, obviously, the described example is only a part of the utility model example, rather than all examples, in the case of no conflict, the example and the feature in the example in the application can be combined mutually, all other examples that the person skilled in the art obtains based on the example in the utility model without making creative labor belong to the scope of the utility model protection.

[0024] Referring to Figures 1 to 3 .

[0025] The utility model discloses a special mixing hopper of drilling machine, including fixed base 1 and the funnel body 2 of setting on fixed base 1, the top of this funnel body 2 is equipped with the inlet 21, and the mixing material enters the funnel body 2 from the inlet 21, and the bottom of this funnel body 2 is equipped with the slurry inlet 22 and slurry outlet 23 with internal communication respectively, and the slurry in the slurry pit is mixed with the mixing material in the funnel body 2 after entering the funnel body 2 through the slurry inlet 22 and then flows out from the slurry outlet 23 to the slurry pit or to the drilling well.

[0026] In the specific implementation, when mixing the slurry in the slurry pit, after calculating the weight of each type of mixing material to be added, the mixing hopper can be slowly poured into, and then the slurry pump is started, the slurry in the slurry pit is pumped into the funnel body 2 through the slurry inlet 22, and the slurry and the mixing material in the funnel body 2 are mixed and then flow back to the slurry pit from the slurry outlet 23 with the mixing material, so that the slurry in the slurry pit and the mixing material can be quickly and fully mixed in a short time after multiple cycles.

[0027] However, since the potassium salt stratum fusion cavity and annular fissure have great uncertainty, the mixed slurry may not be able to complete the plugging, the mixing hopper of the utility model can also be used in the process of delivering the slurry to the drilling well, specifically, the slurry pump pumps the slurry into the funnel body 2, and then the slurry outlet 23 on the funnel body 2 leads to the slurry pit or to the drilling well, when it is found that the existing slurry is not enough to plug, the large particle aggregates (such as stones) and sawdust can be quickly poured into the funnel body 2, so that these materials are delivered to the drilling well with the slurry to plug, and the response is rapid.

[0028] The utility model, when mixing the mixing material and the slurry, does not need manual stirring, and the mixing material and the slurry are mixed quickly, the mixing material is not easy to accumulate at the bottom of the slurry pit, and the mixing material and the slurry can be quickly and fully mixed in a short time.

[0029] It should be noted that, for the light density of the grouting material (such as sawdust) or powder grouting material (such as cement), it is difficult to mix the grouting material uniformly in the slurry by using the traditional stirring method (sawdust will float on the slurry, and cement will easily form larger groups and stick to the bottom of the pool), and after using the grouting funnel, it will be easier to mix in the slurry (sawdust and cement will be directly wrapped and come out, and cement will not easily form groups or only form smaller groups, and will not easily stick to the bottom of the pool).

[0030] Preferably, the slurry inlet 22 and the water outlet pipe of the slurry pump can be connected by a quick connector. Since the slurry pump and the quick connector are well known to those skilled in the art, they are common parts on the market, and therefore will not be described in detail here.

[0031] In an embodiment, the top of the funnel body 2 is provided with a supporting platform 3 for supporting the grouting material. In this way, workers can temporarily place bagged cement, sawdust and other materials on the supporting platform 3 to facilitate the tearing of the bagged materials and pouring them into the funnel body 2.

[0032] In an embodiment, the supporting platform 3 is provided with a weighing component for weighing the materials placed on the supporting platform 3. In this way, it is more convenient to weigh the amount of grouting material placed.

[0033] Preferably, the weighing component can be a metering scale, platform scale, etc. in the prior art.

[0034] In an embodiment, the inside of the funnel body 2 is provided with a support net 4, which is located above the slurry inlet 22 and the slurry outlet 23, and the mesh diameter of the support net 4 is greater than the particle diameter of the grouting material. In this way, the support net 4 can support part of the pressure from the material above, reducing the pressure on the material at the slurry inlet 22 and the slurry outlet 23, so that the material is more easily mixed with the slurry and output with the slurry from the slurry outlet 23, and the arrangement of the support net 4 will not affect the normal falling of the material.

[0035] It should be noted that the support net 4 can also be a support hole plate, a support rod group, etc.

[0036] In an embodiment, at least one first flow guide plate 24 is arranged in the slurry outlet 23, which is used to guide the slurry to rotate spirally in the slurry outlet 23. In this way, the slurry can be better mixed with the light density of the grouting material (such as sawdust) or the powder grouting material (such as cement), so that the grouting material in the discharged slurry is not easily layered.

[0037] In an embodiment, at least one second guide plate 25 is arranged in the slurry outlet 23, and the second guide plate 25 is used to guide the slurry to rotate spirally into the funnel body 2. In this way, on the one hand, the slurry entering the funnel body 2 can be better mixed with the proportioning material in the funnel body 2, and on the other hand, the proportioning material in the funnel body 2 can be more easily disturbed, so that the proportioning material in the funnel body 2 cannot be normally discharged due to arching (i.e., the bottom of the proportioning material forms an arch shape and does not fall). In other words, the slurry spirally entering the funnel body 2 is not easy to make the proportioning material in the funnel body 2 arch, and can destroy the arching when it is initially formed.

[0038] In an embodiment, a top cover (not shown in the figure) is arranged at the top of the funnel body 2, and the top cover is used to open and close the inlet 21 at the top of the funnel body 2. In this way, the slurry pressure entering the funnel body 2 can be prevented from overflowing from the top of the funnel body 2.

[0039] When the present application is used, the following states exist:

[0040] When proportioning, the weighed proportioning material is poured into the funnel body 2, the inlet of the slurry pump is communicated with the slurry pool, the outlet of the slurry pump is communicated with the slurry inlet 22, the slurry outlet 23 is communicated with the slurry pool, the slurry in the slurry pool enters the funnel body 2 through the slurry inlet 22, is mixed with the proportioning material in the funnel body 2, and then carries the proportioning material to flow back to the slurry pool from the slurry outlet 23, and the above process is repeated until the proportioning is completed.

[0041] When the slurry is transported, the inlet of the slurry pump is communicated with the slurry pool, the outlet of the slurry pump is communicated with the slurry inlet 22, the slurry outlet 23 is communicated with the drilling well, and the proportioning material is poured into the funnel body 2 when the current slurry cannot plug the leak, the slurry in the slurry pool enters the funnel body 2 through the slurry inlet 22, is mixed with the proportioning material in the funnel body 2, and then carries the proportioning material to be transported to the drilling well from the slurry outlet 23.

[0042] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0043] It should be noted that if the embodiments of the present application involve directional indications (such as up and down), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly.

[0044] In addition, the meaning of "and / or" appearing in the whole text includes three parallel schemes, taking "A and / or B" as an example, including A scheme, or B scheme, or A and B scheme. In addition, if there is a description of "first", "second" and the like in the utility model embodiment, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features. In addition, "multiple" means more than two. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist, also not within the protection scope required by the utility model.
