Description

Technical Field

[0001] This invention relates to the field of land consolidation equipment technology, and in particular to a land consolidation equipment based on land use and protection. Background Technology

[0002] In land use and conservation projects, land preparation equipment is often used to loosen hard soil layers and level the land. After initially breaking up the hard soil layer, the equipment further breaks up larger clods to ensure soil loosening and fragmentation. However, existing land preparation equipment can only perform soil fragmentation and cannot remove stones mixed in with the soil, which can negatively impact crop growth during subsequent planting.

[0003] According to the search, Chinese patent application CN119111139A discloses a mobile field land leveling device. The device breaks up the soil with the tip of the soil-breaking and turning head. Larger soil clods enter the soil-breaking chamber for shearing and breaking. However, the entire device does not screen out stones mixed in with the soil. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide a land preparation device based on land use and protection that can solve or at least alleviate the above-mentioned problems, so as to effectively break up soil clods and screen out stones mixed in the soil during the soil preparation process to avoid affecting the growth of crops.

[0005] This invention provides a land preparation device based on land use and protection, comprising a housing and a soil-turning component, a soil-crushing and screening component, and a leveling component mounted on the housing. The soil-turning component turns over the soil and performs initial crushing. The soil-crushing and screening component shovels up the turned and initially crushed soil for secondary crushing and filters out stones mixed in with the soil. The leveling component levels the soil crushed by the soil-crushing and screening component. The soil-crushing and screening component includes a soil-crushing component, a screening component, and a mixing component. The soil-crushing component and the screening component are rotatably mounted on the housing. The mixing component is installed in the screening component, and during the rotation of the screening component, it simultaneously drives the mixing component to rotate. By repeatedly crushing the soil through the soil-turning and soil-crushing and screening components, larger soil clods can be effectively broken up, while stones are filtered out by the screening component of the soil-crushing and screening component. Furthermore, during the soil crushing and screening process, the mixing component can further crush soil clods and prevent soil clods from getting stuck in the screening component.

[0006] Furthermore, the soil turning assembly includes a first rotating shaft rotatably mounted on the housing, a soil turning component mounted on the outer peripheral side of the first rotating shaft, and a first rotating component mounted on an axial end of the first rotating shaft; the soil breaking assembly is disposed obliquely above the soil turning assembly, and includes a second rotating shaft rotatably mounted on the housing, a second rotating component mounted on an axial end of the second rotating shaft, and soil breaking teeth mounted on the outer peripheral side of the second rotating shaft.

[0007] Furthermore, the screening assembly includes a plurality of screening elements arranged circumferentially, each screening element being bent outwards; two adjacent screening elements are adjacent to each other; the screening element includes a screening element body and a plurality of teeth disposed on both sides of the screening element body.

[0008] Furthermore, the screening element body is C-shaped, with multiple through holes. The teeth are L-shaped, with the teeth of adjacent screening elements corresponding to each other. During the rotation of the screening element, the soil-crushing teeth partially intersect with the teeth. This partial intersection breaks up the soil clods located between them, and the broken soil clods fall through the through holes, while larger stones remain on the screening element body, thus further breaking up the soil and separating it from the stones.

[0009] Furthermore, mounting plates are respectively installed at both ends of the screening component; a support shaft is fixed to the outside of the mounting plate; the screening component is rotatably mounted on the housing via the support shaft, which is a hollow shaft with openings at both ends.

[0010] Further, the mixing assembly includes a fixed shaft, a fixed seat, a first gear, a mixing element, and a second gear. The fixed shaft is mounted on the housing and sleeved within the support shaft. One end of the fixed shaft protruding from the housing is mounted on the housing via a support. The fixed seat is mounted on the side of the mounting plate opposite to the support shaft and is hollow. The first gear is fixed to the fixed seat. The other end of the fixed shaft passes through the mounting plate and the fixed seat and is mounted on a mounting seat. The mixing element is rotatably mounted on the mounting seat, and a second gear is mounted on the end of the mixing element adjacent to the first gear, with the second gear engaging with the first gear. This configuration allows the mixing element to rotate in the opposite direction as the screening element rotates, breaking up soil clods entering the mixing assembly and preventing soil clods from getting stuck in the screening assembly, thereby improving the breaking efficiency.

[0011] Furthermore, the leveling component is installed on the lower end of the housing and includes multiple leveling teeth, each of which has a liquid outlet hole.

[0012] Furthermore, the housing includes a top plate, side plates located on both sides of the top plate, a sieve plate disposed opposite to the top plate, and a partition chamber disposed between the top plate and the sieve plate; the top plate and the sieve plate are provided with multiple through holes at positions corresponding to the partition chamber.

[0013] Furthermore, the screening plate is inclined upwards, and the screening plate has multiple inclined teeth on the side facing the soil turning component; during the rotation of the screening component, the inclined teeth can partially intersect with the toothed part.

[0014] Furthermore, the land reclamation device based on land use and protection also includes a storage tank installed on the shell, the storage tank containing microbial agents, and the storage tank being connected to the leveling teeth via a connecting pipe. The microbial agents in the storage tank enter the leveling teeth through the connecting pipe and then enter the soil through the outlet holes on the leveling teeth, thereby delivering the microbial agents to the soil for remediation.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The land consolidation device based on land use and protection provided by the present invention can effectively break up large soil clods by repeatedly crushing the soil through the soil turning component and the soil crushing and screening component, and at the same time, the screening component of the soil crushing and screening component can screen out stones to avoid affecting the growth of crops.

[0016] 2. In this invention, the soil crushing teeth and the toothed part are set to partially intersect. During the rotation, the soil block located between the two is crushed, and the crushed soil block falls through the through hole, while the larger stone block is located on the screening body, thereby further crushing the soil and separating the soil from the stone block.

[0017] 3. The stirring component in this invention can rotate in the opposite direction as the screening component rotates, which breaks up the soil clods entering the stirring component and prevents the soil clods from getting stuck in the screening component, thereby improving the crushing efficiency.

[0018] 4. In this invention, during the process of leveling the soil, the microbial agent in the storage tank enters the leveling teeth through the connecting pipe and enters the soil through the liquid outlet on the leveling teeth, thereby delivering the microbial agent to the soil for remediation.

[0036] like Figure 1 and Figure 2 As shown, the land reclamation device based on land use and protection provided by the present invention includes a housing 1, and a soil turning component 2, a soil crushing and screening component 3, and a leveling component 4 installed on the housing 1. The soil turning component 2 turns up the soil and performs preliminary crushing, the soil crushing and screening component 3 shovels up the turned and preliminarily crushed soil, performs further crushing, and screens out stones mixed in with the soil, and the leveling component 4 levels the soil crushed by the soil crushing and screening component 3.

[0037] Also refer to Figure 3The soil turning assembly 2 includes a first rotating shaft 21 rotatably mounted on the two side plates 15 of the housing 1, a soil turning component 22 mounted on the outer periphery of the first rotating shaft 21, and a first rotating component 23 mounted on one axial end of the first rotating shaft 21. Preferably, the first rotating component 23 is a gear. The soil turning component 22 can adopt a structure already existing in the prior art, which will not be specifically described here. The soil crushing and screening assembly 3 further crushes and screens the soil turned up and initially crushed by the soil turning component 22.

[0038] Also refer to Figure 4 and Figure 5 The soil crushing and screening assembly 3 includes a soil crushing assembly 31, a screening assembly 32, and a mixing assembly 33. The soil crushing assembly 31 is positioned diagonally above the soil turning assembly 2. The soil crushing assembly 31 includes a second rotating shaft 311 rotatably mounted on two side plates 15, a second rotating member 312 mounted on one axial end of the second rotating shaft 311, and soil crushing teeth 313 mounted on the outer periphery of the second rotating shaft 311. Preferably, the second rotating member 312 includes multiple gears and is located on the same side of the housing 1 as the first rotating member 23. The soil crushing teeth 313 extend radially outward along the second rotating shaft 311. The screening assembly 32 includes multiple screening members 322 arranged circumferentially. Preferably, the number of screening members 322 is three. (See also...) Figure 6 Each screening element 322 is bent outwards. Adjacent screening elements 322 are adjacent to each other. Each screening element 322 includes a screening element body 221 and multiple teeth 222 disposed on both sides of the screening element body 221. Preferably, the screening element body 221 is generally C-shaped. Multiple through holes are provided on the screening element body 221. The teeth 222 are L-shaped. Preferably, the multiple teeth 222 are evenly spaced. The teeth 222 of adjacent screening elements 322 correspond to each other. During the rotation of the screening element 322, the soil-crushing teeth 313 can partially intersect with the teeth 222.

[0039] Also refer to Figures 7 to 10The screening element 322 has mounting plates 321 installed at both ends. A support shaft 323 is fixed to the outer side of the mounting plate 321. The screening element 322 is rotatably mounted on the side plate 15 of the housing 1 via the support shaft 323. Preferably, the support shaft 323 is a hollow shaft with openings at both ends. A third rotating element 324 is installed on the outer side of the support shaft 323. Preferably, the third rotating element 324 is a gear. Preferably, the third rotating element 324 and the second rotating element 312 are located on the same side of the housing 1. As the screening element 322 rotates, the soil is scooped up by the teeth 222. With the rotation of the screening element 322, small soil particles pass through the through holes on the teeth 222 and the screening element body 221. Soil clods remain on the screening element 322. When the soil clods rotate to the soil crushing component 31, they are crushed by the crushing teeth 313 and the teeth 222. The crushed soil passes through the through holes on the teeth 222 and the screening element body 221. Stones remain on the screening element 322 and enter the housing 1 as the screening element 322 rotates, thus removing stones from the soil. During the rotation of the screening element 322, the stirring component 33 installed in the screening component 32 also rotates, further crushing the soil clods and preventing them from getting stuck in the screening component 32.

[0040] The stirring assembly 33 includes a fixed shaft 331, a fixed seat 333, a first gear 334, a stirring element 335, and a second gear 336. The fixed shaft 331 is mounted on the housing 1 and is sleeved within a support shaft 323. Preferably, one end of the fixed shaft 331 protruding from the housing 1 is mounted on the housing 1 via a support 14. Preferably, the support 14 is generally U-shaped. The fixed seat 333 is mounted on the side of the mounting plate 321 opposite to the support shaft 323. Preferably, the fixed seat 333 is hollow. The first gear 334 is fixed to the fixed seat 333. The other end of the fixed shaft 331 passes through the mounting plate 321 and the fixed seat 333 and is mounted on a mounting seat 332. The stirring element 335 is rotatably mounted on the mounting seat 332. Preferably, there are three stirring elements 335. The second gear 336 is mounted on one end of the stirring element 335 adjacent to the first gear 334, and the second gear 336 engages with the first gear 334. Preferably, the agitator 335 has multiple protrusions extending radially outward on its outer periphery. When the mounting plate 321 rotates, the first gear 334 drives the second gear 336 to rotate, causing the agitator 335 to rotate, thereby breaking and mixing the soil clods entering the screening assembly 32, preventing soil clods from getting stuck in the screening assembly 32. The leveling assembly 4 levels the soil. (Back) Figures 1 to 3 The leveling component 4 is installed on the lower end of the housing 1 and includes multiple leveling teeth 41. The leveling teeth 41 are provided with liquid outlet holes.

[0041] Also refer to Figure 3 and Figure 11The housing 1 includes a top plate 11, side plates 15 located on both sides of the top plate 11, a screening plate 13 opposite to the top plate 11, and a partition chamber 12 disposed between the top plate 11 and the screening plate 13. Multiple through holes are provided on the top plate 11 and the screening plate 13 at positions corresponding to the partition chamber 12. Preferably, the screening plate 13 is inclined upwards. More preferably, the screening plate 13 is bent upwards towards the soil-turning assembly 2 and is provided with multiple inclined teeth 131. During the rotation of the screening element 322, the inclined teeth 131 can partially intersect with the teeth 222. Preferably, during the rotation of the screening element 322, the end of the inclined tooth 131 adjacent to the screening element 322 contacts the screening element body 221, thereby scraping away soil clods or stones stuck in the through holes of the screening element body 221.

[0042] Also refer to Figure 1 , Figure 2 and Figure 11 The land preparation device also includes a storage tank 5 installed on the housing 1. Preferably, the storage tank 5 contains microbial inoculants. The storage tank 5 is connected to the leveling teeth 41 of the leveling component 4 via a connecting pipe 51. The two ends of the connecting pipe 51 are respectively connected to the corresponding through holes of the top plate 11 and the sieve plate 13. The microbial inoculants in the storage tank 5 enter the leveling teeth 41 through the connecting pipe 51 and enter the soil through the outlet holes 411 on the leveling teeth 41, thereby delivering the microbial inoculants to the soil for remediation. Preferably, a connecting rod 52 is provided on one side of the storage tank 5 for connection to a traction vehicle.

[0043] Preferably, a drive assembly 6 is mounted on the housing 1. The drive assembly 6 includes a motor 61, a drive component 62 mounted on the output shaft of the motor 61, and a transmission component 63 connected to the second rotating component 312. Preferably, the drive component 62 is a gear, and the transmission component 63 is a chain.

[0044] When motor 61 operates, it drives the second rotating component 312 to rotate. The second rotating component 312 drives the first rotating component 23 and the third rotating component 324 to rotate, thereby driving the soil turning assembly 2, the soil crushing assembly 31, and the screening assembly 32 to rotate simultaneously. The soil turning component 22 of the soil turning assembly 2 turns up the soil and performs preliminary crushing. The soil crushing and screening assembly 3 shovels up the turned and initially crushed soil for further crushing and screening out stones mixed in with the soil. The leveling assembly 4 levels the soil crushed by the soil crushing and screening assembly 3. Specifically, the third rotating component 324 drives the mounting plate 321 and the screening component 322 to rotate via the support shaft 323. During the rotation of the screening component 322, the soil is scooped up by the teeth 222. As the screening component 322 rotates, small soil particles pass through the through holes on the teeth 222 and the screening component body 221, and soil clods remain on the screening component 322. When the soil clods rotate to the soil crushing component 31, they are crushed by the soil crushing teeth 313 and the teeth 222. The crushed soil passes through the through holes on the teeth 222 and the screening component body 221, and stones remain on the screening component 322. As the screening component 322 rotates, it enters the screening plate 13 of the housing 1, thereby screening out the stones in the soil. When the mounting plate 321 rotates, the first gear 334 drives the second gear 336 to rotate, causing the stirring component 335 to rotate, thereby crushing and stirring the soil clods entering the screening component 32, preventing soil clods from getting stuck in the screening component 32. When the leveling component 4 levels the soil, the microbial agent in the storage tank 5 enters the leveling tooth 41 through the connecting pipe 51 and enters the soil through the outlet hole 411 on the leveling tooth 41, thereby delivering the microbial agent to the soil for remediation.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
