Description

Technical Field

[0001] The utility model belongs to the technical field of soil improvement, and in particular relates to a soil compaction improvement device. Background Art

[0002] Soil compaction is a common and serious problem in agricultural production, especially under long-term heavy tillage, single crop planting and unreasonable irrigation. A hardened layer is easily formed on the soil surface, which hinders the penetration of water, air and nutrients, resulting in restricted crop root growth and reduced yield.

[0003] The traditional method of improving soil compaction is mainly through deep tillage. When using deep tillage to alleviate the problem of soil compaction, the surface soil layer and the soil layer near the surface are turned up and the compacted soil is broken up to form a loose soil structure, which is conducive to the infiltration and circulation of air, water and nutrients, thereby promoting the healthy growth of plants.

[0004] However, the soil in some areas with strong winds may become compacted. When traditional deep plowing methods are used to improve the soil, the surface soil layer is also loosened, which is easily affected by wind erosion when encountering strong winds, and may lead to soil and water loss. Utility Model Content

[0005] The utility model aims to provide a soil compaction improving device to solve the problem that the surface soil is also broken up after deep plowing in the existing deep plowing method proposed in the above background technology, which may cause soil and water loss under strong wind conditions.

[0006] To achieve the above object, the utility model provides the following technical solutions: a soil compaction improvement device, comprising a square frame, a power box located above the square frame, and a rotary cutter connected to the power box, a curved plate is arranged at the lower part of the square frame, a front shovel is arranged on one side of the curved plate, guard plates are arranged on opposite sides of the curved plate, a first fixing block and a second fixing block are arranged on the separated sides of the two guard plates, and the curved plate is fixed to the square frame via the first fixing block and the second fixing block;

[0007] A plurality of grooves are provided on the top of the curved plate, a runway-shaped plate is formed at each of the grooves of the curved plate, and a belt is slidably sleeved on each of the runway-shaped plates.

[0008] In one of the embodiments, a plurality of scraping grooves are provided on the curved plate, and positions of the scraping grooves correspond to positions of the grooves one by one.

[0009] In one of the embodiments, each group of the scraping grooves comprises a plurality of scraping grooves, and a scraping block is fixed on the top of each scraping groove, and the scraping block acts on the belt.

[0010] In one of the embodiments, a support frame is fixed on the top of the square frame, and the power box is located on the top of the support frame.

[0011] In one of the embodiments, a through hole penetrating through the square frame is provided at a position on the top of the square frame near the support frame.

[0012] In one of the embodiments, bottom fixing blocks are fixed on both sides of the bottom of the curved plate, and the rotary cutter is rotatably disposed between the two bottom fixing blocks.

[0013] Beneficial Effects

[0014] Technical effects and advantages of the soil compaction improvement device:

[0015] When the soil compaction improvement device is used to deal with the soil compaction problem, the tractor is moved with the soil compaction improvement device, the driving unit is turned on and the rotary cutter is rotated via the power box, during the movement, the front shovel will move toward the underground and shovel the surface soil layer to the top of the curved plate, after the surface soil layer is shoveled up, the underground compacted soil layer is broken and loosened under the action of the rotary cutter, at this time the soil layer will become higher, and the soil layer lifted by the curved plate will fall on the top of the broken soil layer after passing through the curved plate, and the soil compaction improvement device can make the surface soil layer fall on the top of the broken soil layer under the action of the curved plate when in use, so that the surface soil layer will not be broken, and the probability of soil and water loss under heavy rain or strong wind conditions can be reduced.

[0016] When the surface soil moves to the top of the curved plate, the soil will rotate with the belt on the curved plate. At this time, some soil will adhere to the surface of the belt and enter the groove. The scraper will scrape off the soil on the surface of the belt. This structure can reduce the probability of the belt being unable to rotate due to soil blocking the groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In order to avoid confusion with the present invention, some technical features known in the art are not described.

[0027] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0028] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0029] Please refer to Figure 1-Figure 4 A soil compaction improvement device shown in the figure includes a square frame 101, a power box 301 located above the square frame 101, and a rotary cutter 305 connected to the power box 301. The square frame 101 is fixed with relevant structures connected to the tractor, such as a lower pull rod, an upper pull rod and a power output shaft (the power output shaft is a transmission shaft connected to the tractor drive unit, and this transmission shaft is connected to the power box 301) and other structures. A gear transmission structure is arranged in the power box 301, which can transmit the power of the tractor drive unit to the rotary cutter 305. Since a curved plate 201 is provided between the rotary cutter 305 and the power box 301, the technical solution does not directly connect the rotary cutter 305 to the power box 301.

[0030] Wheels 102 are installed on the side of the square frame 101 to facilitate movement on the ground.

[0031] In this embodiment, a curved plate 201 is arranged at the lower part of the square frame 101, a front shovel 202 is arranged on one side of the curved plate 201, guard plates 203 are arranged on opposite sides of the curved plate 201, and a first fixing block 204 and a second fixing block 205 are arranged on the side where the two guard plates 203 are separated, and the curved plate 201 is fixed to the square frame 101 via the first fixing block 204 and the second fixing block 205.

[0032] like Figure 1 , Figure 2 As shown, the curved plate 201 is located below the square frame 101, and the side of the curved plate 201 close to the front shovel 202 is an arc section with the center located above the curved plate 201, followed by an arc section with one end of the center located below the curved plate 201, and the side of the curved plate 201 away from the front shovel 202 is a horizontal section. The curved plate 201 is fixed to the square frame 101 via a first fixing block 204 and a second fixing block 205. When the soil compaction improving device is installed on a tractor, the front shovel 202 is located on the side close to the tractor, and the front shovel 202 is in a downwardly inclined shape so that it can enter the soil.

[0033] In this embodiment, a plurality of grooves 211 are provided on the top of the curved plate 201, and a runway-shaped plate 212 is formed at each groove 211 of the curved plate 201. A belt 213 is slidably sleeved on each runway-shaped plate 212. A plurality of groups of scraping grooves are provided on the curved plate 201, and the positions of the scraping grooves correspond one-to-one to the positions of the grooves 211. Each group of scraping grooves includes a plurality of scraping grooves 214, and a scraping block 215 is fixed on the top of each scraping groove 214, and the scraping block 215 acts on the belt 213.

[0034] like Figure 3 , Figure 4 As shown, the curved plate 201 is slidably connected to a plurality of belts 213 via a runway plate 212, so that the friction between the belts 213 and the runway plate 212 is reduced by lubricating oil or graphite powder. When the surface soil layer moves onto the curved plate 201, the soil layer slides with the belts 213, which can reduce the friction of the soil layer when moving on the curved plate 201, and facilitate the movement of the surface soil layer. However, some soil will adhere to the surface of the belt 213 during this process. At this time, during the rotation of the belt 213, it will stick to the scraper block 215, and the soil scraped off by the scraper block 215 will fall down along the scraper groove 214, which can reduce the possibility of soil accumulation in the groove 211, so that the soil will not get stuck on the belt 213 and affect its rotation, and can ensure that the belt 213 can rotate to a certain extent.

[0035] In this embodiment, a support frame 302 is fixed on the top of the square frame 101, and the power box 301 is located on the top of the support frame 302. A through hole 303 that penetrates the square frame 101 itself is opened at the top of the square frame 101 near the support frame 302. Bottom fixing blocks 304 are fixed on both sides of the bottom of the curved plate 201. The rotary cutter 305 is rotatably set between the two bottom fixing blocks 304. A shield 306 is fixed at the bottom of the square frame 101 near the bottom fixing block 304 to protect the rotating shaft of the rotary cutter 305 set on the bottom fixing block 304, which can reduce the probability of the rotating shaft of the rotary cutter 305 contacting the soil.

[0036] like Figure 1 , Figure 2 As shown, when the present technical solution is designed, the power of the power box 301 is transmitted to a position close to the through hole 303 through the transmission rod along the direction of the support frame 302, and then the transmission rod passes through the through hole 303 and is connected to the rotating shaft of the rotary tool 305, driving the rotary tool 305 to rotate, and the transmission rods are connected by transmission gears.

[0037] Working principle: When the soil compaction improvement device is used to deal with the soil compaction problem, the soil compaction improvement device is fixed to the rear of the tractor, so that the front shovel 202 is on the side close to the tractor, and the power box 301 is connected to the driving unit of the tractor. When the soil compaction improvement device moves from above the ground to close to the ground, after the front shovel 202 is attached to the ground, the tractor moves with the soil compaction improvement device, and the driving unit is turned on to rotate with the rotary cutter 305 through the power box 301. During the movement, the front shovel 202 will move toward the ground and dig the ground. The surface soil layer is shoveled to the top of the curved plate 201. At this time, the surface soil layer moves in the direction away from the front shovel 202 under the action of the belt 213 on the curved plate 201, and the surface soil layer is lifted by the curved plate 201. After the wheel 102 is attached to the ground, the front shovel 202 cannot continue to move underground, but it will shovel up the surface soil layer above. After the surface soil layer is shoveled up, the compacted soil layer underground is broken and loosened under the action of the rotary cutter 305. At this time, the soil layer will become higher, and the soil layer lifted by the curved plate 201 will fall on the top of the broken soil layer after passing through the curved plate 201.

[0038] When the surface soil layer moves to the top of the curved plate 201 , the soil layer will rotate with the belt 213 on the curved plate 201 . At this time, some soil will adhere to the surface of the belt 213 and enter the groove 211 , and the scraper 215 will scrape off the soil on the surface of the belt 213 .

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
