Description

Technical Field

[0001] The utility model relates to the field of building construction, and specifically relates to a hole cleaning device for drilling. Background Art

[0002] The statements in this part only provide background technical information related to the utility model, and do not necessarily constitute prior art.

[0003] During the building construction process, when drilling a hole, it is necessary to ensure that the soil on the side wall does not collapse, and it is also necessary to ensure that the bottom of the hole is horizontal and there is no accumulation of soil chips. Therefore, after drilling, it is necessary to clean the bottom of the drilled hole, and when cleaning the hole, it is also necessary to prevent the collapse of the side wall soil. Therefore, it is necessary to reduce the contact with the side wall. Usually, a casing is set on the side wall to prevent the collapse of the side wall soil at the joint between the casing and the soil. Then, the bottom of the hole is cleaned. And how to ensure that the soil chips at the bottom of the hole are collected and taken out during the cleaning process is a problem to be solved, to reduce the accumulation of soil chips at the bottom of the hole.

[0004] For a drilled hole, the head of the drill bit is mostly conical. Therefore, when drilling, the bottom of the drilled hole will present a conical state, and the conical state cannot provide stable support after the hole is poured. Therefore, it is necessary to process the bottom of the drilled hole to make the bottom of the drilled hole horizontal. Therefore, how to process the soil at the bottom of the drilled hole and prevent the collapse of the side wall soil is a problem to be solved.

[0005] When the soil is collected and taken out, if there is too much soil to be processed in the hole, it needs to be processed multiple times. Therefore, it is necessary to pour out the soil collected in the device and then re-enter the drilled hole to collect the soil. Therefore, how to facilitate the pouring out of the soil and make the device reduce manual operation and enable the machine to automatically perform the operation of pouring out the soil is a problem to be solved.

[0028] The following further elaborates the present utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0029] The utility model relates to a hole cleaning device for drilling. The main structure includes a protection cylinder 1, a cutter cylinder 2, and a storage cylinder 3. The protection cylinder 1 is arranged on the outermost side and plays a role in protecting the cutter cylinder 2 and the storage cylinder 3. And a connecting column 10 is provided at the top of the protection cylinder 1. The function of the connecting column 10 is to install the whole device on the drilling device, that is, to move the device down to the bottom of the drilling hole to clean the soil at the bottom of the drilling hole. During the cleaning process, the device rotates and descends in the same way as the drilling device. And the inside of the connecting column 10 is hollow, and a driving motor 12 is provided to control the rotation of the storage cylinder 3. Limiting members 7, chutes 8, etc. are also provided on the inner side wall of the protection cylinder 1. So that the limiting members 7 and the chutes 8 are respectively adapted to the tracks 6 on the storage cylinder 3 and the sliders 9 on the outer side wall of the cutter cylinder 2 (detailed below). And the diameter of the protection cylinder 1 here needs to be less than or equal to the diameter of the drilling hole, so that the device can be placed at the bottom of the drilling hole.

[0030] The cutter cylinder 2 is arranged between the protection cylinder 1 and the storage cylinder 3. A cutter 4 is provided at the bottom of the cutter barrel. When the device rotates, the cutter 4 collects the soil chips at the bottom of the drilling hole and drills the soil, etc. So that the soil chips enter the storage cylinder 3 for collection. And a plurality of sliders 9 are provided on the outer side wall of the cutter cylinder 2. And the plurality of sliders 9 are respectively adapted to the chutes 8 on the protection cylinder 1, so that the cutter cylinder 2 can move up and down (continued from the above text). And a plurality of through holes are provided on the cutter cylinder 2. The through holes are for the limiting members 7 to pass through the through holes and contact the tracks 6 on the storage cylinder 3, thereby controlling the rotation of the storage cylinder 3. The plurality of sliders 9 on the cutter cylinder 2 are arranged in a circumferential array on the outer side wall of the cutter cylinder 2. Here, the cutter cylinder 2 is arranged in a 180° circumferential array. And through holes are also provided between two cutter cylinders 2. The through holes are also arranged in a 180° circumferential array. So that the limiting members 7 can provide a supporting effect for the tracks 6 while contacting the tracks 6. The cutter 4 at the bottom of the cutter cylinder 2 is inclined, so that the cutter head part of the cutter 4 extends beyond the bottom of the cutter cylinder 2, so as to be able to cut the soil. As shown in the attached drawings of the specification Figure 1 As shown, after the two cutter head parts cut and collect the soil, the space of the cutter 4 part enters the storage cylinder 3 to collect the soil.

[0031] A rotating shaft 11 is provided at the top of the storage cylinder 3, and the rotating shaft 11 is arranged inside the connecting column 10. The rotating shaft 11 is connected to the driving motor 12 inside the connecting column 10. Specifically, one end of the rotating shaft 11 is connected to the output end of the driving motor 12. Since the storage cylinder 3 needs to move up and down, and in order to better fix the driving motor 12, etc., a telescopic shaft 13 is provided between the rotating shaft 11 and the output end of the driving motor 12. The setting of the telescopic shaft 13 enables the driving motor 12 to control its rotation when the storage cylinder 3 moves up and down. Since the outer side of the storage cylinder 3 is provided with a track 6, and the track 6 is arc-shaped, as shown in the accompanying drawings of the specification Figures 6-7 As shown, when the storage cylinder 3 is pushed upward or moves downward, it can drive the rotation of the storage cylinder 3. However, due to some special circumstances, such as excessive accumulation of soil chips between the cutter cylinder 2 and the storage cylinder 3, causing the storage cylinder 3 to be unable to move downward normally. Therefore, the rotation of the storage cylinder 3 is controlled by the driving motor 12 to ensure the up and down movement process of the storage cylinder 3. When the storage cylinder 3 can rotate by itself during the up and down movement, it is impossible to directly obtain the state of the storage cylinder 3 at this time. Therefore, the driving motor 12 is used to control its rotation. To prevent the rotation angle from being too large, a clamping protection groove 15 is provided on the rotating shaft 11 of the storage cylinder 3. The function of the clamping protection groove 15 is that when the storage cylinder 3 can complete the rotation by itself, the telescopic shaft 13 controlled by the driving motor 12 idles in the clamping protection groove 15. When it cannot rotate by itself, the clamping protection groove 15 is pushed by the clamping member 16 provided at one end of the telescopic shaft 13, that is, the rotation of the storage cylinder 3. The storage cylinder 3 is rotated to a specified position. Since the storage cylinder 3 needs to carry the soil chips and discharge them away from the drill hole after the soil chips are carried away, it is necessary to ensure that the storage cylinder 3 can be fixed at different heights. Therefore, a track 6 is provided. After the limiting member 7 contacts different height positions of the track 6, the supporting function is realized. A plurality of soil inlet openings 5 are provided at the bottom of the storage cylinder 3. The soil inlet openings 5 are adapted to the cutting tools 4 on the cutter cylinder 2, so that the soil chips can enter the storage cylinder 3. The track 6 is divided into upper and lower ends, and the positions of the soil inlet openings 5 and the upper and lower ends of the track 6 are as shown in the accompanying drawings of the specification Figure 7 As shown, the soil inlet openings 5 are close to the lower end of the track 6.

[0032] When the limiting member 7 is at the bottom end of the track 6, the top of the entire storage cylinder 3 is in contact with the inner top of the protection cylinder 1, and at this time, the bottom of the cutter cylinder 2 is in contact with the soil, so as to collect soil debris. If the bottom of the cutter cylinder 2 is not in contact with the soil at this time, that is, it is suspended. Then the soil debris in the storage cylinder 3 is discharged along the soil inlet 5 and the position of the cutter 4. When the limiting member 7 is at the top end of the track 6, the top of the entire storage cylinder 3 is separated from the inner top of the protection cylinder 1, and at this time, the storage cylinder 3 is separated from the positions of the soil inlet 5 and the cutter 4, and the entire storage cylinder 3 moves downward, so that the bottom of the storage cylinder 3 is in contact with the bottom of the cutter cylinder 2. Therefore, the soil is enclosed in the storage cylinder 3 and taken out. And when the limiting member 7 is at the top end of the track 6, at this time, a part of the bottom of the storage cylinder 3 and the cutter cylinder 2 leaks outside the protection cylinder 1, as shown in the accompanying drawings of the specification Figures 8-9 shown, so that the device can complete steps such as soil sampling, carrying, and discharging.

[0033] It also includes a control terminal, and the control terminal is connected to the driving motor 12 to control the rotation of the driving motor 12. The driving motor 12 is selected as a stepping motor here. The connection between the control terminal and the driving motor 12 can be connected through a circuit, that is, a power transmission line is provided outside the machine connected to this device, so as to connect the control terminal and the driving motor 12. And this device can also be provided with components such as a power supply in the connecting column 10, so that the control terminal controls the rotation of the driving motor 12 through electrical signals, etc. The specific situation needs to be specifically set according to different environments.

[0034] Detailed description of the usage method:

[0035] Install this device at the position of the drilling cutter, and then adjust the driving motor 12 and the storage cylinder 3 through debugging, so that the storage cylinder 3 and the cutter cylinder 2 are in the corresponding positions. When this device moves downward and contacts the soil, due to the reaction force of the soil on the cutter 4, the cutter 4 will move upward, that is, the top of the storage cylinder 3 is in contact with the inner top of the protection cylinder 1. At this time, the soil inlet 5 on the storage cylinder 3 is aligned with the cutter 4, so that the soil can enter the storage cylinder 3 during the rotation process. After rotating for a certain time, then drive the driving motor 12 through the control device to make the storage cylinder 3 rotate, and this device is lifted upward at the same time. Since the vertical height difference of the track 6 is approximately the same as the length of the sliding groove 8, when the rotation of the storage cylinder 3 is completed, the bottom of the storage cylinder 3 fits with the cutter cylinder 2, thereby preventing the soil from falling out of the storage cylinder 3. When this device is removed and then contacts the ground, the storage cylinder 3 and the cutter cylinder 2 are lifted upward, so that the soil inlet 5 is aligned with the cutter 4 again, and this time the device is slowly lifted upward so that the soil flows out of the soil inlet 5. The rotation of this device can be controlled by the driving motor 12, and the storage cylinder 3 can move up and down through the track 6, etc.

[0036] As shown in the accompanying drawings of the specification Figures 8-9 shown, the accompanying drawings of the specification Figure 8 corresponds to the four parts A, B, C, and D in the accompanying drawings of the specification. That is, when in part A in Figure 9 the position of the soil inlet 5 and the cutting tool 4 is as shown in part A of the accompanying drawings of the specification, so that soil chips can enter the storage cylinder 3. Then, during recovery, the storage cylinder 3 moves downward, and the drive motor 12 rotates, so that the storage cylinder 3 and the cutter cylinder 2 reach the attachment Figure 8 position B shown in the accompanying drawings of the specification, so that the soil chip storage cylinder 3 is in contact with the cutter cylinder 2, and then the soil chips are temporarily stored in the storage cylinder 3 and carried out of the drill hole. Then, the cutter cylinder 2 and the storage cylinder 3 are brought into contact with the bottom surface to reach the attachment Figure 9 position C shown in the accompanying drawings of the specification. Then, the device is slowly lifted upward, and at this time, the drive motor 12 does not rotate, so that the storage cylinder 3 is separated from the cutter cylinder 2, and the soil chips in the storage cylinder 3 are discharged through the soil inlet 5. Then, the entire device reaches the attachment Figure 8 state D shown in the accompanying drawings of the specification. After all the soil chips are discharged, the device is placed back into the drill hole, and then the soil chips are collected Figure 8 In summary, through the settings of the track 6 and the drive motor 12, the device can rotate, so as to ensure that there are two states of contact and separation at the bottom of the cutter cylinder 2 and the storage cylinder 3, so that the device can temporarily store soil chips and the like in the storage cylinder 3. The device is also provided with a drive motor 12, so that the drive motor 12 plays a protective role in the rotation of the storage cylinder 3, that is, to prevent the storage cylinder 3 from getting stuck and other situations. A clamping protection groove 15 is provided on the rotating shaft 11 connected to the storage cylinder 3, and the setting of the clamping protection groove 15 prevents the drive motor 12 from controlling the excessive rotation of the storage cylinder 3. The device controls its rotation through the up and down movement of the drive motor 12 and the storage cylinder 3, realizes the functions of taking soil and discharging soil, and reduces manual intervention Figure 8 In summary, through the settings of the track 6 and the drive motor 12, the device can rotate, so as to ensure that there are two states of contact and separation at the bottom of the cutter cylinder 2 and the storage cylinder 3, so that the device can temporarily store soil chips and the like in the storage cylinder 3.
