Description

Technical Field

[0001] This invention belongs to the field of soil compaction technology, specifically relating to a soil compaction device for afforestation in high-altitude and cold regions. Background Technology

[0002] Afforestation is the production process of establishing new forests on barren land. It is often used as a synonym for artificial afforestation. Barren land refers to suitable barren mountains, wastelands, logging sites, burned areas, tidal flats, sandy wastelands, and abandoned mining sites, generally collectively referred to as afforestation-suitable land. Afforestation has become a means of utilizing bioenergy, protecting the environment, and achieving harmony between humans and nature. Since ancient times, humans have understood the use of tree planting and logging, a practice with a long history. However, high-altitude and cold regions, due to their consistently low temperatures, frequent freeze-thaw cycles, and unique soil structures, present challenging conditions for forestry afforestation. During seedling planting, soil compaction is a crucial step in ensuring close contact between the roots and the soil and preventing frost damage.

[0003] Traditional manual compaction (such as foot treading and wooden rammers) is inefficient and produces poor uniformity. While existing mechanical compaction devices (such as vibratory plate compactors and impact rollers) achieve soil densification by driving a compaction plate with a rigid vibration mechanism to impact the soil at high frequency, the vibration intensity and the final soil density have a non-linear relationship. Operators cannot adjust the compaction output force according to the real-time conditions of the high-altitude soil (such as moisture content and thawing depth), resulting in uncontrollable soil compaction. Therefore, we propose a soil compaction device for afforestation in high-altitude and cold regions to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that when using existing mechanical compaction devices, the operator cannot adjust the compaction output force according to the real-time condition of the cold soil, resulting in uncontrollable soil compaction.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A soil compaction device for afforestation in high-altitude and cold regions includes a box that can move in the forest under external force, a compaction block that is movably installed in the box, and a hoisting mechanism that can pull the compaction block upward and release it at any height. The lower end of the box is provided with an opening for the lower end of the compaction block to pass through, and the hoisting mechanism is set on the box.

[0007] Further specifying, the hoisting mechanism includes two support columns fixedly mounted on the upper end of the housing, a rotating roller rotatably mounted between the two support columns, a hoisting rope fixedly connected at one end to the rotating roller, and a driving component capable of driving the rotating roller to rotate. The two support columns are provided with mounting holes, and the rotating shaft of the rotating roller is rotatably mounted within the mounting holes. A through hole is provided at the upper end of the housing, and the other end of the hoisting rope is movably connected to the compacted block through the through hole. This structural design, by driving the rotating roller to rotate via the driving component, allows the hoisting rope to be wound up, thereby lifting the compacted block upwards to complete the force-accumulating operation of the compaction device.

[0008] Further specifying, the driving component includes a rotating handle, a fixed rod fixed to one end of the rotating handle, a fixed block fixedly installed at the junction of the fixed rod and the rotating handle, and a limiting end fixedly installed at the end of the fixed rod away from the fixed block. The rotating roller has a slot at its center and a limiting groove and a retaining groove communicating with the slot. The limiting groove and retaining groove are located at opposite ends of the slot. The fixed rod, fixed block, and limiting end are movably installed within the slot, retaining groove, and limiting groove, respectively. When the limiting end extends into the limiting groove, the fixed block disengages from the retaining groove. This structural design allows the rotating roller to rotate when the fixed block is in the retaining groove, and when the fixed block disengages from the retaining groove, the fixed rod and rotating roller are rotatably connected, facilitating the lifting and lowering of the compacted block.

[0009] Further specifying, an annular groove is provided on the support column near the rotating handle, located outside the mounting hole. A ratchet is rotatably mounted within the annular groove, and an opening for the rotating handle to pass through is provided in the center of the ratchet. A protrusion is provided within the opening. A strip-shaped groove is provided on the rotating handle, and the protrusion is slidably mounted within the strip-shaped groove. A fixing post is also fixedly mounted on the support column near the rotating handle, and a pawl adapted to the ratchet is rotatably mounted on the fixing post. A torsion spring is provided at the rotatable connection between the fixing post and the pawl. With this structural design, when the rotating handle, in conjunction with the rotating roller, lifts the compacted block, the ratchet and pawl can lock the position of the rotating roller, facilitating the maintenance of the lifted state of the compacted block.

[0010] Furthermore, a mounting frame is fixedly installed on the compacted block, and the mounting frame is equipped with pulleys. The end of the lifting rope passes around the pulleys and is fixedly connected to the top of the inner wall of the box. This structural design, with the pulleys and lifting ropes, can extend the lifting boom, making it more labor-saving during use.

[0011] Furthermore, both the box and the compacted block are arc-shaped structures, and the box has several ventilation holes. This structural design, with its arc shape, is more suitable for soil compaction during afforestation, and the ventilation holes ensure the proper falling of the compacted block.

[0012] Furthermore, the compaction block consists of two parts, upper and lower, with the edge of the upper part extending beyond the lower part. Multiple compression springs, adapted to the upper part of the compaction block, are fixedly installed on the bottom of the inner wall of the housing. This structural design, with the compression springs, prevents the compaction block from directly contacting the bottom of the inner wall of the housing when it falls, thus preventing damage to the housing.

[0013] Further specifying, the box body has a movable frame and two symmetrically arranged fixed frames on each side. The lower ends of the movable frame and the two fixed frames are rotatably mounted with rotating wheels. The movable frame is frame-shaped, and two limiting rods are fixedly mounted on it vertically. Limiting seats adapted to the two limiting rods are fixedly mounted on the box body. A hydraulic cylinder is fixedly mounted within the frame of the lower part of the movable frame, and a fixed seat is fixedly mounted on the box body. The upper end of the hydraulic cylinder is fixedly connected to the fixed seat. This structural design allows the hydraulic cylinder, in conjunction with the movable frame, to adjust the tilt angle of the box body, thereby adjusting the compaction angle of the compaction device during operation.

[0014] Furthermore, a push handle is fixedly installed at the upper end of the box, and the push handle is covered with anti-slip rubber. This structural design is simple and easy to use.

[0015] The invention employing the above technical solution has the following advantages:

[0016] 1. In this invention, the lifting mechanism can pull the compacted block upward and release it at any height. The compacted block impacts the soil to produce a compaction effect. The operator can adjust the lifting height of the compacted block according to the real-time condition of the high-altitude soil, thereby adjusting the impact force of the compacted block on the soil and keeping the degree of soil compaction within a controllable range.

[0017] 2. In this invention, the rotating roller is rotated by turning the handle, thereby winding the lifting rope and lifting the compacted block. With the cooperation of the ratchet and pawl, the compacted block can be kept in the lifted state. Pulling the handle away from the rotating roller will switch the rotating roller to the active state. At this time, the compacted block will accelerate under the action of gravity until it hits the ground and produces a compaction effect on the ground. The whole process is controlled by the rotating handle, making it more convenient to use. Attached Figure Description

[0036] like Figures 1-5 As shown, this invention discloses a soil compaction device for afforestation in high-altitude and cold regions. It includes a box 1 that can move in the forest under external force, a compaction block 2 movably installed inside the box 1, and a lifting mechanism 3 that can pull the compaction block 2 upwards and release it at any height. The lower end of the box 1 has an opening through which the lower end of the compaction block 2 passes. A strip-shaped observation port with transparent glass embedded in it is provided on one side of the box 1, allowing easy observation of the lifting height of the compaction block 2 inside the box 1. The lifting mechanism 3 is mounted on the box 1. Both the box 1 and the compaction block 2 have an arc-shaped structure, making them more suitable for compacting soil around tree roots after afforestation. Several ventilation holes are provided on the box 1 to ensure the smooth drop of the compaction block 2 inside. A push handle 7 is fixedly installed at the upper end of the box 1, facilitating the overall pushing of the compaction device. The push handle 7 is covered with anti-slip rubber, increasing the friction between the operator's hand and the push handle 7 while improving grip comfort.

[0037] The hoisting mechanism 3 includes two support columns 31 fixedly installed on the upper end of the housing 1, a rotating roller 32 rotatably installed between the two support columns 31, a hoisting rope 33 with one end fixedly connected to the rotating roller 32, and a driving component that can drive the rotating roller 32 to rotate. The two support columns 31 are provided with mounting holes, and the rotating shaft of the rotating roller 32 is rotatably installed in the mounting holes. A through hole is opened at the upper end of the housing 1, and the other end of the hoisting rope 33 is movably connected to the compaction block 2 through the through hole.

[0038] The driving component includes a rotating handle 4, a fixed rod 41 fixed to one end of the rotating handle 4, a fixed block 42 fixedly installed at the junction of the fixed rod 41 and the rotating handle 4, and a limiting end 43 fixedly installed at the end of the fixed rod 41 away from the fixed block 42. The rotating roller 32 has a slot in the center and a limiting groove and a slot connected to the slot. The limiting groove and the slot are located at both ends of the slot. The fixed rod 41, the fixed block 42 and the limiting end 43 are movably installed in the slot, the slot and the limiting groove respectively. When the limiting end 43 is inserted into the limiting groove, the fixed block 42 disengages from the slot. At this time, the rotating handle 4 and the fixed rod 41 are rotatably connected to the rotating roller 32, and the compaction block 2 is in a movable state. If the compaction block 2 is suspended at a certain height, it will fall down from this height until it contacts the ground and compacts the ground.

[0039] An annular groove 311 is provided on the support column 31 near the rotating handle 4. The annular groove 311 is located outside the mounting hole. A ratchet 312 is rotatably installed in the annular groove 311. An opening for the rotating handle 4 to pass through is provided in the center of the ratchet 312. A protrusion is provided in the opening. A strip groove is provided on the rotating handle 4. The protrusion is slidably installed in the strip groove. A fixing column 313 is also fixedly installed on the support column 31 near the rotating handle 4. A pawl 314 that matches the ratchet 312 is rotatably installed on the fixing column 313. A torsion spring is provided at the rotatable connection between the fixing column 313 and the pawl 314.

[0040] A mounting frame is fixedly installed on the compacted block 2. The mounting frame is equipped with a pulley 5. The end of the suspension rope 33 passes around the pulley 5 and is fixedly connected to the top of the inner wall of the box 1. The compacted block 2 consists of two parts, upper and lower, with the edge of the upper part extending beyond the lower part. Multiple compression springs 6 that are compatible with the upper part of the compacted block 2 are fixedly installed on the bottom of the inner wall of the box 1.

[0041] The two sides of the housing 1 are respectively provided with a movable frame 11 and two symmetrically arranged fixed frames 12. The lower ends of the movable frame 11 and the two fixed frames 12 are rotatably mounted with rotating wheels 13. The movable frame 11 is frame-shaped, and two limit rods 14 are fixedly installed on the movable frame 11 along the vertical direction. The housing 1 is fixedly installed with limit seats 15 that are compatible with the two limit rods 14. The lower part of the movable frame 11 is fixedly installed in its frame, and a fixed seat 17 is fixedly installed on the housing 1. The upper end of the hydraulic cylinder 16 is fixedly connected to the fixed seat 17.

[0042] The method of using this invention is as follows:

[0043] In use, push the handle 7 to push the entire compaction device to the planting location of the tree, so that it is above the backfill soil. Push the handle 7 towards the rotating roller 32. When the fixed block 42 is in the slot, apply force to make the handle 4 and the rotating roller 32 rotate. The rotating roller 32 will wind up the hanging rope 33 and lift the compaction block 2 upward through the hanging rope 33 until the compaction block 2 is lifted to the required height.

[0044] When the rotating handle 4 drives the rotating roller 32 to rotate, the ratchet 312 rotates accordingly. The pawl 314 engages the rotating handle 4 and the rotating roller 32 in a one-way manner through the ratchet 312, which can keep the rotating roller 32 and the lifting rope 33 in the state of lifting the compacted block 2. When it is necessary to release the compacted block 2 from the set height, pull the rotating handle 4 outward to make the fixed block 42 disengage from the slot, so that the fixed rod 41 and the rotating roller 32 are in a rotating connection relationship. At this time, the compacted block 2 will accelerate downward under the action of gravity until it contacts the ground and impacts the landfill soil to compact the soil.

[0045] When compacting sloping landfill soil, the position of the movable frame 11 can be adjusted by the hydraulic cylinder 16 to adjust the tilt angle of the box 1, so that the compaction block 2 hits the ground at a certain angle. After compaction, the slope of the landfill soil can be maintained.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
