Description

Technical Field

[0001] This invention relates to the field of soil loosening devices, and in particular to soil loosening devices for upper coal and rock layers. Background Technology

[0002] A ripper is a replaceable working device with crushing and loosening functions. It is used to excavate cracked rock, break frozen soil, and also to dig up asphalt pavement. It is suitable for crushing and splitting hard soil, medium-hard rock, and weathered rock to facilitate excavation and loading operations using a bucket. Existing rippers, also called ripping teeth, are mainly used on excavators or bulldozers. They are relatively large and cannot perform precise, small-scale loosening at fixed points. The loosening method tends to directly damage the soil surface. In coal seam dewatering and sampling operations, this method can damage the underlying coal seam and the roof above it, directly affecting subsequent excavation and sampling work. The large size also results in low loosening efficiency. Therefore, a device is designed that can perform precise and efficient small-scale loosening through precise positioning, suitable for loosening work that does not affect the soil surface and roof.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0032] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0033] Example 1

[0034] Reference Figure 1-5This embodiment provides a soil loosening device for upper coal and rock layers, including a control platform 100. The control platform 100 is a base component fixed on the soil surface, including a flat plate 101. The flat plate 101 is provided with a through-cylinder boss 102. The through-cylinder boss 102 has a positioning function. The soil loosening component loosens the soil below by passing through the through-cylinder boss 102. The through-cylinder boss 102 is provided with a liquid-applying pipe 102a and a track-passing ball rod 102b on both sides. The liquid-applying pipe 102a is placed inside the through-cylinder boss 102 and filled with ferrous sulfate solution to enhance the soil loosening efficiency. The track-passing ball rod 102b is a fixed short rod with a rolling ball at the end. The through-cylinder boss 102 is provided with a through-hole 102c at the center. The through-hole 102c is used to allow other soil loosening components to pass through and loosen the upper soil layer. The bottom of the flat plate 101 is provided with liquid storage fixing pipes 103 on both sides. The function of the liquid storage fixing pipes 103 is to fix the entire control platform 100 on the soil surface. The transmission components inside can enhance the stability of the fixation.

[0035] Furthermore, the soil-breaking and embedding tube 200 is a tubular component that enters the soil, including a soil-embedding tube 201. The positioning tip 201a at the bottom of the soil-embedding tube 201 facilitates the soil-embedding tube 201 to penetrate the soil surface and enter the soil interior. The soil-embedding tube 201 is fixedly connected to the bottom of the paving plate 101. Pressing the paving plate 101 as a whole can insert the soil-embedding tube 201 into the soil. The soil-embedding tube 201 is provided with a needle cavity 202, which is a key component used to loosen the soil in the fixed position area.

[0036] Example 2

[0037] Reference Figure 1-8 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and differs from the previous embodiment in that: the needle cavity 202 is provided with a needle positioning hole 202a. The needle positioning hole 202a can be used to pass through the soil-breaking long needle 203 that breaks the soil clods and reset them. A strong and tough spring 202b is symmetrically fixedly connected in the needle cavity 202. The strong and tough spring 202b is responsible for achieving the reset effect. One end of the needle positioning hole 202a is in the needle cavity 202, and the other end passes through the inner wall of the soil-embedded tube 201 and is placed outside the needle cavity 202. The whole is fixed and passes through the soil-embedded tube 201. The needle cavity 202 has a rhomboid shape, with spikes V at all four ends. The spikes V facilitate the loosening of the soil inside the soil-embedding tube 201 after it enters the soil, preventing obstruction during its descent. The needle cavities 202 are evenly and equidistantly arranged on the inner wall of the soil-embedding tube 201, and the multi-directional arrangement facilitates the loosening of the soil in multiple directions.

[0038] A soil-breaking long needle 203 is slidably connected within the needle positioning hole 202a. The soil-breaking long needle 203 is a key component of the entire device used for loosening the soil. One end of the soil-breaking long needle 203 inside the needle cavity 202 has a smooth end A, and the other end outside the needle cavity 202 has a sharp end B. The smooth end A has no sharp edges and will not damage the components inside the soil-embedding tube 201, while the sharp end B has sharp edges and can break up the external soil. The middle part is the sliding column L, which is the main part inside the needle positioning hole 202a. The sliding column L is used to move stably within the hole. The top of the soil-breaking needle 203 has a smooth curved surface M. The smooth curved surface M facilitates the generation of smooth friction force on the special end of the soil-breaking needle 203 after contacting other parts, causing the soil-breaking needle 203 to move. The bottom end is a rounded corner surface N. The rounded corner design can cut through the soil below and ensure that it will not be damaged when it encounters other parts.

[0039] The long needle 203 is equipped with a fixing plate 203a at one end near the smooth end A. The fixing plate 203a is symmetrically arranged on the long needle 203. One end of the strong spring 202b is fixedly connected to the inner wall of the needle cavity 202, and the other end is fixedly connected to the fixing plate 203a. This allows the long needle 203 to be reset by the strong spring 202b after it is obstructed and displaced. The strong spring 202b itself is stronger than the ordinary spring 202b and is not affected by the soil when it is diving.

[0040] Example 3

[0041] Reference Figure 1-9 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: a driving pipe rod 300 is provided at the opening 102c. The driving pipe rod 300 is mainly responsible for cooperating with the soil-breaking embedding pipe 200 and its internal components to produce a true soil-breaking effect. This includes a sinking pipe 301, which can pass through the opening 102c and sink into the soil through the positioning of the opening 102c. Similarly, the sinking pipe 301... The ground-breaking tip 301b at the bottom of 01 is used to allow the component to sink smoothly into the soil. The outer wall of the sinking tube 301 is provided with a spiral rail 301a, which covers the entire surface of the sinking tube 301. The top of the sinking tube 301 is provided with a rotating boss 302, which is rotatably connected to the entire sinking tube 301. The rotating boss 302 is provided with a handle 302a, which can be pressed down to allow the entire sinking tube 301 to move downward from the opening 102c.

[0042] Furthermore, the diameter of the sinking pipe 301 is the same as that of the through-hole 102c, allowing it to pass through and slide through the through-hole 102c, ensuring smooth cooperation between the sinking pipe 301 and the through-hole 102c. The sinking pipe 301 is equipped with a spiral loosening rod 303, which allows the sinking pipe 301 to fully break up and loosen the soil below the positioning position during the sinking process. If the sinking pipe 301 rotates, the spiral loosening rod 303 will rotate along with it. The drill bit 303a at the end of the spiral loosening rod 303 ensures that the entire sinking pipe 301 and the spiral loosening rod 303 inside can drill through the soil and sink smoothly. The rotating spiral loosening rod 303 has extremely high soil loosening efficiency.

[0043] Furthermore, the opening of the liquid-applying pipe 102a is tightly attached to the outer wall of the sinking pipe 301. When the sinking pipe 301 breaks through the soil downwards through the opening 102c, the ferrous sulfate solution in the liquid-applying pipe 102a will cover the surface of the sinking pipe 301. The end of the guide rod 102b near the sinking pipe 301 is equipped with a ball bearing 102b-1, which is embedded in the spiral rail 301a. This design allows the sinking pipe 301 to be driven by the ball bearing 102b-1 during the sinking process, thus rotating continuously. The rotating shaft boss 302 provides the axial center for the rotation. When the worker manually or using tools controls the handle 302a to press down the sinking pipe 301, the entire sinking pipe 301 will rotate in the direction of the spiral rail 301a. At the same time, the spiral loosening rod 303 will also rotate, allowing the soil below the sinking pipe 301 to be fully loosened.

[0044] In detail, the spiked end B of the soil-breaking needle 203 can be embedded in the spiral rail 301a, which is the main condition for achieving soil loosening. When the sinking tube 301 moves downward, the soil-breaking needle 203 will disengage from the sinking tube 301 and, under the action of the strong spring 202b and the smooth curved surface M of the soil-breaking needle, will be pushed out of the embedded tube 201 along the needle positioning hole 202a, thereby piercing and crushing the soil around the embedded tube 201. The uniformly spaced and omnidirectionally arranged soil-breaking needles 203 can efficiently and stably loosen the soil area of ​​360°. Due to the curved trajectory characteristics of the spiral rail 301a, each soil-breaking needle 203, after one outward push, It will also reset, which also relies on the effect of the rounded corner surface N of the soil-breaking needle 203. The smooth curved surface M contacts the spiral rail 301a with the rounded corner surface N. When the sinking tube 301 is submerged, the smooth curved surface M contacts the spiral rail 301a and generates thrust. When the sinking tube 301 is rising, the rounded corner surface N contacts the spiral rail 301a and generates thrust. When the soil-breaking needle 203 is pushed out, it will be limited by the outer wall of the sinking tube 301. At this time, the characteristics of the smooth end A ensure that it will not cause any damage to the sinking tube 301. After encountering the spiral rail 301a again, it will extend and retract once more. During the up and down movement of the sinking tube 301, the soil-breaking needle 203 will continuously move in and out, achieving periodic soil loosening work.

[0045] Example 4

[0046] Reference Figure 1-9 This is the fourth embodiment of the present invention. This embodiment is based on the previous embodiment, and the difference from the previous embodiment is that: the liquid storage fixing tube 103 includes a pressing tube 103a, an adjusting collar 103b, and a liquid storage plug 103c. The three are connected to each other. The pressing table 104 controls and connects to whether the pressing tube 103 is pressed down, forming a controllable fixed connection between the entire device and the land.

[0047] The pressure tube 103a has an L-shaped slot 103a-1. A pressure block 103a-2 is located at the bottom of the inner wall of the pressure tube 103a. A certain gap exists between the two symmetrically arranged pressure blocks 103a-2 and the inner wall of the pressure tube 103a. The adjusting collar 103b has a through groove 103b-1, which consists of two symmetrically arranged quarter-circular grooves. A control rod 103b-2 is fixedly connected to the adjusting collar 103b. The control rod 103b-2 consists of a horizontal... It consists of a rod and a vertical rod. The end of the vertical rod has a short horizontal rod. This short horizontal rod passes through the slot 103a-1 and makes a circular motion around the vertical rod in the slot 103a-1, which drives the adjusting collar 103b to rotate in the pressure tube 103a. The top of the liquid storage plug 103c is provided with a block inlet groove 103c-1. The block inlet groove 103c-1 is the same as the through groove 103b-1, which is two symmetrically arranged quarter-circular grooves. The liquid storage plug 103c is provided with multiple liquid outlet holes 103c-1 evenly spaced.

[0048] The liquid storage plug 103c is fitted inside the pressure tube 103a. The liquid storage plug 103c is fitted inside the pressure tube 103a through the gap between the pressure block 103a-2 and the pressure tube 103a. The adjusting collar 103b is placed between the pressure tube 103a and the liquid storage plug 103c and is rotatably connected to the pressure tube 103a. The control rod 103b-1 is placed inside the pressure tube 103a and passes through the slot 103a-1, that is, the short crossbar passes through the slot 103a-1 for the operator to adjust. The pressure block 103a-2, the through slot 103b-1 and the inlet slot 103c-1 are coaxially arranged and have the same diameter. This means that when the operator adjusts the control rod 103b-1, causing the adjusting collar 103b to rotate, a series of different states will occur. The liquid storage plug 103c has a soil-penetrating tip Y at the bottom, which facilitates the insertion of the entire liquid storage fixing tube 103 into the soil.

[0049] State 1: Rotate the adjusting collar 103b so that the through groove 103b-1 does not coincide with the inlet groove 103c-1 and the pressing block 103a-2. The adjusting collar 103b can prevent the pressing block 103a-2 from entering the inlet groove 103c-1. At this time, it is in a non-pressing state and no reaction will occur.

[0050] State 2: Rotate the adjusting collar 103b to align the through groove 103b-1, the inlet groove 103c-1, and the lower pressure block 103a-2. Press down the pressing table 104 to press down the lower pressure tube 103a. At this time, the control rod 103b-1 makes a vertical relative displacement in the L-shaped slot 103a-1, allowing the lower pressure block 103a-2 to sink and pass through the through groove 103b-1, entering the inlet groove 103c-1, and thus entering the liquid storage plug 103c. The liquid storage plug 103c is filled with 108 soil granule adhesive. The liquid outlet 103c-1 is temporarily blocked by a membrane. When the pressure block 103a-2 presses down on the liquid inside the liquid storage plug 103c, the liquid will break through the membrane. 108 soil granule adhesive is a kind of adhesive that can fully integrate and bond with the soil. Thus, after the entire liquid storage fixing tube 103 is inserted into the soil, by pressing down the pressure tube 103a, it achieves temporary adhesion with the upper soil layer, stabilizing the entire device on the land surface.
