Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drilling machine technology, specifically relating to a drilling machine for water conservancy projects. Background Technology
[0002] Water conservancy projects are a general term for various engineering constructions undertaken to control, utilize, and protect surface and underground water resources and the environment. Drilling machines are frequently used in water conservancy construction. A drilling machine is a collective term for machinery and equipment that uses a tool harder and sharper than the target object to create cylindrical holes or cavities through rotary cutting or rotary extrusion. When drilling soft soil layers with water, existing drilling machines cause the soil-water mixture to be flung upwards and outwards by centrifugal force during the rotation of the drill rod, leading to mud pollution of the surrounding environment. This also increases the difficulty of operation for workers, making them impractical. Furthermore, the muddy ground makes workers prone to slipping and reducing safety. Utility Model Content
[0003] This utility model provides a drilling machine for water conservancy projects. Its purpose is to solve the problems of existing drilling machines when drilling soft soil layers with water. During the rotation of the drill rod, the mixture of soil and water mud is thrown upward and to the sides by centrifugal force, causing mud pollution to the surrounding environment. This also increases the difficulty of operation for workers, making it impractical. Furthermore, when the ground is covered with mud and becomes slippery, workers are prone to slipping and reducing safety.
[0004] This utility model provides a drilling machine for water conservancy projects, including a base, a fixed plate fixed on the base, an extension plate fixed on one side of the base, a water tank and a circulation pump on the extension plate, a sliding cavity in the middle of the fixed plate, a driving mechanism in the sliding cavity, a drilling mechanism on the driving mechanism, and a splash guard on the fixed plate.
[0005] Furthermore, the driving mechanism includes a lead screw rotatably mounted in the sliding cavity, a mounting plate sliding in the sliding cavity, the mounting plate being threadedly connected to the lead screw, a first motor being mounted on the top of the fixed plate, and the top of the lead screw being fixed to the output end of the first motor.
[0006] By adopting the above technical solution, the drive mechanism composed of the lead screw and the first motor realizes precise lifting control of the mounting plate. The first motor drives the lead screw to rotate, causing the mounting plate to move vertically along the sliding cavity.
[0007] Furthermore, the sliding cavity has grooves on both sides, and the mounting plate slides in the grooves on both sides.
[0008] By adopting the above technical solution, the grooves on both sides of the sliding cavity slide in conjunction with the two sides of the mounting plate to form a double guide structure, preventing the mounting plate from deflecting or getting stuck during the lifting process; the groove depth matches the thickness of the mounting plate, which not only ensures smooth sliding but also reduces displacement deviation caused by vibration.
[0009] Furthermore, the drilling mechanism includes a second motor mounted on the side of the mounting plate away from the extension plate, and a drill rod is fixed to the downward-facing output end of the second motor.
[0010] By adopting the above technical solution, the second motor directly drives the drill rod, eliminating the need for traditional belt or gear transmission structures and reducing energy loss.
[0011] Furthermore, the splash guard includes a horizontal plate fixed to the bottom of the wall surface of the fixed plate away from the extension plate, and a splash guard sleeve is fixed to the lower side of the horizontal plate.
[0012] By adopting the above technical solution, the splash-proof part composed of the horizontal plate and the splash-proof sleeve forms a semi-enclosed working space. The splash-proof sleeve is made of flexible and wear-resistant material, and its bottom fits adaptively when in contact with the ground, preventing mud from splashing horizontally.
[0013] Furthermore, the splash guard is hollow, narrow at the top and wide at the bottom, and the bottom of the splash guard is aligned with the bottom of the base.
[0014] By adopting the above technical solution, the hollow structure of the splash guard, which is narrow at the top and wide at the bottom, optimizes the direction of mud flow. The wide opening at the bottom increases the contact area with the ground, enhances the sealing performance, and increases the splash protection range. The bottom of the splash guard is aligned with the bottom of the base to ensure that the splash guard can fit in contact with the ground during drilling.
[0015] Furthermore, the top of the horizontal plate is provided with a through hole, which is aligned with the drill rod.
[0016] By adopting the above technical solution, the through hole at the top of the horizontal plate is aligned with the drill rod on the same axis, ensuring that the vertical movement of the drill rod is free from interference; the diameter of the through hole is slightly larger than the diameter of the drill rod, which allows the drill rod to rise and fall freely while preventing mud from overflowing from the top.
[0017] Furthermore, the outlet of the water tank is connected to the inlet of the circulation pump, and the outlet of the circulation pump is connected to the inside of the splash guard.
[0018] By adopting the above technical solution, the circulating pump delivers water from the water tank to the inside of the splash guard, forming a dynamic water curtain. The water flows down along the inner wall of the splash guard. The flow rate of the circulating pump is adjustable, and the amount of water injected is matched according to the hardness of the stratum, so as to avoid excessive water injection and aggravation of mud splashing.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1. This utility model achieves precise lifting and lowering control of the mounting plate by setting up a drive mechanism. The drive mechanism composed of a lead screw and a first motor drives the lead screw to rotate, thereby moving the mounting plate vertically along the sliding cavity.
[0021] 2. By setting up the splash-proof part, the splash-proof part composed of the horizontal plate and the splash-proof sleeve forms a semi-enclosed working space. At the same time, the bottom of the splash-proof sleeve adapts to fit when in contact with the ground, blocking the horizontal splashing of mud. The wide opening structure at the bottom of the splash-proof sleeve increases the contact area with the ground, enhances the sealing performance, and increases the splash-proof range.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] Reference Figure 1-3 This utility model provides a drilling machine for water conservancy projects, including a base 1, a fixed plate 2 fixed on the base 1, an extension plate 3 fixed on one side of the base 1, a water tank 4 and a circulating pump 5 mounted on the extension plate 3, a sliding cavity 6 in the middle of the fixed plate 2, a driving mechanism 7 in the sliding cavity 6, the driving mechanism 7 including a lead screw 71 rotatably mounted in the sliding cavity 6, an mounting plate 72 sliding in the sliding cavity 6, the mounting plate 72 being threadedly connected to the lead screw 71, a first motor 73 mounted on the top of the fixed plate 2, the top of the lead screw 71 being fixed to the output end of the first motor 73, the driving mechanism 7 consisting of the lead screw 71 and the first motor 73 realizes precise lifting and lowering control of the mounting plate 72, the first motor 73 driving the lead screw 71 The rotation drives the mounting plate 72 to move vertically along the sliding cavity 6. The left and right sides of the sliding cavity 6 are provided with grooves, and the two sides of the mounting plate 72 slide in the grooves. The grooves on both sides of the sliding cavity 6 and the two sides of the mounting plate 72 slide in cooperation, forming a double guide structure to prevent the mounting plate 72 from deflecting or getting stuck during the lifting process. The depth of the groove matches the thickness of the mounting plate 72, which not only ensures smooth sliding but also reduces displacement deviation caused by vibration. During the drilling process, the first motor 73 does not work all the time. The working state of the first motor 73 changes with the drilling situation of the drill rod 82. When the end of the drill rod 82 cannot be drilled through, the first motor 73 is turned off. When the drilling process of the drill rod 82 is smooth, the first motor 73 is working.
[0030] Reference Figure 1-3 The drive mechanism 7 is equipped with a drilling mechanism 8, which includes a second motor 81 mounted on the side of the mounting plate 72 away from the extension plate 3. The output end of the second motor 81 facing downward is fixed with a drill rod 82. The second motor 81 directly drives the drill rod 82, eliminating the need for traditional belt or gear transmission structures and reducing energy loss.
[0031] Reference Figure 1-3The fixed plate 2 is also provided with a splash guard 9, which includes a horizontal plate 91 fixed to the bottom of the side wall of the fixed plate 2 away from the extension plate 3. The top of the horizontal plate 91 has a through hole, and the drill rod 82 is aligned with the through hole. The through hole at the top of the horizontal plate 91 is coaxially aligned with the drill rod 82 to ensure that the vertical movement of the drill rod 82 is uninterrupted. The diameter of the through hole is slightly larger than the diameter of the drill rod 82, which allows the drill rod 82 to move freely up and down while preventing mud from overflowing from the top. A splash guard sleeve 92 is fixed to the lower side of the horizontal plate 91. The splash guard 9, composed of the horizontal plate 91 and the splash guard sleeve 92, is shaped like a splash guard 9. The semi-enclosed working space is formed. The splash guard 92 is made of flexible and wear-resistant material. When its bottom contacts the ground, it adapts to fit and prevents mud from splashing laterally. The splash guard 92 is hollow with a narrow top and a wide bottom. The bottom of the splash guard 92 is aligned with the bottom of the base 1. The hollow structure of the splash guard 92 optimizes the direction of mud flow. The wide opening at the bottom increases the contact area with the ground, enhances the sealing, and increases the splash protection range. The bottom of the splash guard 92 is aligned with the bottom of the base 1 to ensure that the splash guard 92 can fit in contact with the ground during drilling.
[0032] Reference Figure 1-3 The outlet of water tank 4 is connected to the inlet of circulation pump 5, and the outlet of circulation pump 5 is connected to the inside of splash sleeve 92. Circulation pump 5 delivers water from water tank 4 to the inside of splash sleeve 92 to form a dynamic water curtain. The water flows down along the inner wall of splash sleeve 92. The flow rate of circulation pump 5 is adjustable, and the water injection volume is matched according to the hardness of the stratum to avoid excessive water injection and aggravation of mud splashing.
[0033] The specific implementation method is as follows: During drilling, the second motor 81 and the first motor 73 are started. The first motor 73 drives the lead screw 71 to rotate, thereby allowing the mounting plate 72 to move along the lead screw 71. Simultaneously, the second motor 81 drives the drill rod 82 to rotate, achieving the drilling purpose. During drilling, the drill rod 82 passes through the through hole on the horizontal plate 91. At the same time, the circulating pump 5 flushes an appropriate amount of water into the inside of the splash guard 92, and the splash guard 92 blocks the mud and water generated during drilling, preventing the mud and water from splashing under the action of centrifugal force when the drill rod 82 rotates. This avoids the surrounding environment being affected by mud and water, improves overall safety, prevents workers from slipping, and also reduces the problem of increased operational difficulty for workers due to slippery mud and water. The above shows and describes the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
