Description

Technical Field

[0001] The utility model relates to the technical field of Luoyang shovels, in particular to a smoothbore Luoyang shovel. Background Art

[0002] With the rapid development of the national economy, the number of engineering construction projects is increasing, and the requirements for engineering geological exploration are becoming higher and higher. As an important means of obtaining physical geological data, the main task of engineering geological exploration is to take core or undisturbed soil samples in the rock and soil layer. It is required to improve efficiency and ensure the quality of the samples. The natural structure of the sample should be maintained during the sampling process to determine the physical and mechanical properties of the soil and provide a design basis for engineering construction. For deep soil layers or rock samples, mechanical drilling rigs are often used to drill and take rock and soil samples. For shallow soil samples, Luoyang shovels can also be used. As a tool for digging deep holes and collecting soil, Luoyang shovels are easy to carry and have complete functions. Ordinary Luoyang shovels include shovel heads, counterweight rods, extension rods, rings, safety ropes and carrying bags.

[0003] A Luoyang shovel is disclosed in a published Chinese patent (publication number: CN104988958B), including a blade and a weighted rod. The blade is cylindrical, with a soil-taking tube at the bottom and an impact tube at the top. The diameter of the impact tube is larger than the diameter of the soil-taking tube, and an impact tube step is formed at the connection between the impact tube and the soil-taking tube. A blade top cover is fixed on the top of the impact tube, and a blade top cover center hole is provided on the blade top cover. An impact plate is arranged in the impact tube, and a spring is provided between the impact plate and the blade top cover, and the diameter of the impact plate is larger than the diameter of the soil-taking tube but smaller than the diameter of the impact tube. The weighted rod passes through the center hole of the blade top cover and is fixed to the impact plate. A blade bottom edge is provided at the bottom of the soil-taking tube. The prior art sets the impact cylinder on the blade. The blade is cylindrical, with a soil taking cylinder at the bottom and an impact cylinder at the top. Setting the impact cylinder on the blade results in a smaller stroke of the impact cylinder. When the stroke is small, the impact force is greatly weakened. When the impact force of the blade is greatly reduced, the efficiency of the blade in digging into the stratum is low.

[0004] In the published Chinese patent application, the publication number is CN208056147U, and the patent name is: A new type of punching shovel. Although, by setting the structure of the rod body to include a connecting rod, an adjustment ring and an adjustment rod, and by installing an adjustment ring that can slide along the length direction of the adjustment rod and a stop mechanism for limiting the sliding of the adjustment ring on the adjustment rod, the position of the adjustment ring on the adjustment rod is adjusted by sliding the adjustment ring on the adjustment rod, and then the insertion depth of the adjustment rod in the hollow hole is adjusted in conjunction with the screwing in and out of the connecting rod on the adjustment ring, so that when the punching shovel is used for punching operations, the length of the rod body can be adjusted arbitrarily according to actual needs. However, the prior art fixes the adjustment rod and the connecting rod together through a stop mechanism, and the punching shovel shown in the prior art needs to use an external heavy object to hit and knock the adjustment rod when digging into the stratum, and the adjustment rod moves downward after being subjected to force. The prior art uses an external weight device to knock the drilling shovel downward. During geological exploration, it is often in a wilderness environment where it is difficult for the external weight device to reach. The drilling shovel has a low efficiency in digging into the stratum. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides a smoothbore Luoyang shovel, which solves the problems raised in the above-mentioned background technology.

[0007] (II) Technical solution

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: a smooth-bore Luoyang shovel, including a shovel head, an outer cylinder and an inner rod body, the lower end of the outer cylinder body is coaxial with the upper end of the shovel head and is fixedly connected, the internal cavity of the outer cylinder body constitutes a slideway, the lower part of the inner rod body is inserted in the internal cavity of the outer cylinder body, and the inner rod body and the outer cylinder body are slidably connected, the length of the inner rod body is greater than the length of the outer cylinder body; the inner rod body slides down and hits the inner bottom wall of the outer cylinder body, the outer cylinder body moves downward after being hit by the hammer force, and the outer cylinder body pushes the shovel head to move downward.

[0009] Optionally, the shovel head is cast from high-strength carbon steel.

[0010] Optionally, the upper end of the inner rod body is detachably connected to a counterweight body.

[0011] Optionally, at least one first limiting hole is formed on the outer cylinder body, and at least one second limiting hole is formed on the inner rod body. After the lower end of the inner rod body abuts against the inner bottom wall of the outer cylinder body, the first limiting hole and the second limiting hole correspond to each other.

[0012] Optionally, a pull handle is further included, wherein the pull handle includes a handle portion and a hook portion, wherein the hook portion is snapped onto the outer side wall of the inner rod body or the outer cylinder body, and the handle portion and the hook portion are fixedly connected.

[0013] Optionally, the hook portion is composed of a hook and a rubber pad, and the rubber pad is fixedly mounted on the inner wall of the hook.

[0014] Optionally, the handle is composed of a handle and two connecting straps, and the handle is fixedly connected to the hook via the two connecting straps.

[0015] (III) Beneficial effects

[0016] The utility model provides a smooth-bore Luoyang shovel, which has the following beneficial effects:

[0017] 1. The smoothbore Luoyang shovel, through the coordinated arrangement of the shovel head, the outer cylinder and the inner rod body, has the effect of quickly digging into the stratum and breaking through the hard gravel layer. When the Luoyang shovel shown in the present application is drilling, the inner rod body is repeatedly raised and lowered, and the inner rod body quickly drops to the inner bottom wall of the outer cylinder. The inner rod body impacts the inner bottom wall of the outer cylinder, so that the outer cylinder is forced downward as a whole. The outer cylinder pushes the shovel head down, and the shovel head moves downward under the force of gravity, so that the Luoyang shovel can quickly dig into the stratum and break through the hard gravel layer, which greatly improves the efficiency of the Luoyang shovel in digging into the stratum.

[0018] 2. Traditional Luoyang shovels are widely used in drilling operations in the loess plateau area. There are generally disadvantages such as limited well drilling depth and unfavorable attack on the stratum. Modification is carried out to address the existing problems, but the premise of the modification is that the original advantages of the Luoyang shovel, such as lightness and fast movement, cannot be affected. The smoothbore Luoyang shovel shown in this application adopts a smoothbore rod design (the inner rod body slides inside the outer cylinder body) to solve the disadvantages without affecting the original advantages of the Luoyang shovel, such as lightness and fast movement. The double-rod design of the outer cylinder body and the inner rod body increases the actual use length of the Luoyang shovel as a whole, thereby increasing the drilling depth.

[0025] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0027] For example, see Figure 1 to Figure 2 The utility model provides a technical solution: a smoothbore Luoyang shovel, comprising a shovel head 1, an outer cylinder 2 and an inner rod 3, the lower end of the outer cylinder 2 is coaxial with the upper end of the shovel head 1 and fixedly connected, the inner cavity of the outer cylinder 2 constitutes a slideway 4, the lower part of the inner rod 3 is inserted into the inner cavity of the outer cylinder 2, and the inner rod 3 is slidably connected with the outer cylinder 2, and the length of the inner rod 3 is greater than the length of the outer cylinder 2. After sliding down, the inner rod 3 hits the inner bottom wall of the outer cylinder 2, and the outer cylinder 2 moves downward after being hit by the hammer force, and the outer cylinder 2 pushes the shovel head 1 to move downward.

[0028] Among them, the inner wall of the outer cylinder 2 is also the smooth bore, and the inner rod body 3 slides inside the outer cylinder 2. When the inner rod body 3 repeatedly rises and falls and slides, the inner rod body 3 repeatedly impacts and hits the inner bottom wall of the outer cylinder 2. The outer cylinder 2 moves downward after being subjected to force as a whole, and the outer cylinder 2 pushes the shovel head 1 to repeatedly move downward for excavation. The shovel head 1 moves downward for excavation and breaks through the geological gravel layer.

[0029] Specifically, the shovel head 1 is cast from high-strength carbon steel.

[0030] The head of the traditional Luoyang shovel is thin and sharp, but the shovel head is easy to break and damage when it encounters ginger and stone. The smoothbore Luoyang shovel shown in this application is cast with high-strength carbon steel, and the thickness of the shovel head 1 is increased. The inner rod body 3 is made of high-density steel. Under the condition of ensuring that the inner rod body 3 has a certain weight, the inner rod body 3 will not bend under continuous impact.

[0031] When in use, the staff points the shovel head 1 to the ground and repeatedly lifts and pulls the outer cylinder 2 to make the shovel head 1 go down to drill the stratum. After drilling the stratum to a certain depth, the staff repeatedly lifts and releases the inner rod 3. The inner rod 3 repeatedly rises and falls and slides in the outer cylinder 2. The inner rod 3 repeatedly impacts and hits the inner bottom wall of the outer cylinder 2. The outer cylinder 2 moves downward after being subjected to the force as a whole. The outer cylinder 2 pushes the shovel head 1 to repeatedly move downward for excavation. The shovel head 1 moves downward for excavation and breaks through the geological gravel layer.

[0032] For example 2, please refer to Figure 3 to Figure 4 The main difference between this embodiment and the first embodiment is that a counterweight body 7 is detachably connected to the upper end of the inner rod body 3 .

[0033] The heavier the inner rod body 3 is, the greater the impact force of the inner rod body 3 on the outer cylinder body 2 is, and the smoothbore Luoyang shovel has a higher efficiency in digging downward. By arranging a detachable counterweight body 7 at the upper end of the inner rod body 3, an additional counterweight is selectively added to the inner rod body 3, thereby strengthening the impact force of the inner rod body 3 on the outer cylinder body 2 downward.

[0034] Specifically, at least one first limiting hole 5 is formed on the outer cylinder 2, and at least one second limiting hole 6 is formed on the inner rod 3. After the lower end of the inner rod 3 abuts against the inner bottom wall of the outer cylinder 2, the first limiting hole 5 and the second limiting hole 6 correspond to each other.

[0035] Among them, the smoothbore Luoyang shovel shown in the present application can fix the inner rod body 3 and the outer cylinder body 2 by a latch to prevent the inner rod body 3 from sliding out of the outer cylinder body 2 when drilling is not performed. The latch penetrates the first limiting hole 5 on the outer cylinder body 2 and the second limiting hole 6 on the inner rod body 3 to fix the inner rod body 3 and the outer cylinder body 2, so that the inner rod body 3 cannot slide out of the outer cylinder body 2.

[0036] For example 3, please refer to Figure 3 to Figure 4The main difference between this embodiment and the first embodiment is that a smoothbore Luoyang shovel also includes a pull handle 8, the pull handle 8 includes a handle portion and a hook portion, the hook portion is snapped on the outer side wall of the inner rod body 3 or the outer cylinder body 2, and the handle portion and the hook portion are fixedly connected.

[0037] The pull handle 8 is used as an auxiliary tool to facilitate the staff to lift the inner rod body 3 or the outer cylinder body 2, so that the staff can lift the inner rod body 3 or the outer cylinder body 2 with less effort, and avoid the staff directly lifting the inner rod body 3 or the outer cylinder body 2 to cause wear and blisters on the palm. When in use, the staff holds the handle of the pull handle 8, hooks the hook of the pull handle 8 on the outer wall of the inner rod body 3 or the outer cylinder body 2, and pulls the handle of the pull handle 8. The friction between the hook and the outer wall of the inner rod body 3 or the outer cylinder body 2 is relatively large. When the staff lifts the pull handle 8 upward, the inner rod body 3 or the outer cylinder body 2 also moves upward. The pull handle 8 can be removed (disassembled) from the outer wall of the inner rod body 3 or the outer cylinder body 2.

[0038] The hook portion is composed of a hook 801 and a rubber pad 804, and the rubber pad 804 is fixedly mounted on the inner wall of the hook 801. The handle portion is composed of a handle 803 and two connecting straps 802, and the handle 803 is fixedly connected to the hook 801 through the two connecting straps 802.

[0039] The hook 801 can be made of metal material. The rubber pad 804 is used to increase the friction force to ensure that when the staff pulls the handle 8, the inner rod body 3 or the outer cylinder body 2 also moves upward. The connecting belt 802 can be made of hard materials, such as metal, plastic, etc., or a traction belt woven with ropes.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
