Description

Technical Field

[0001] The present invention relates to the technical field of centrifugal separation devices, and particularly to a gravel treatment device for garden soil treatment. Background Art

[0002] With the continuous improvement of people's spiritual and cultural needs, the landscape requirements for the living environment are also getting higher and higher. Gardens can create beautiful landscapes through the combination of elements such as plants, water bodies, buildings, and sculptures, providing people with visual enjoyment. There are various styles of gardens, and a lot of gravel is used as embellishment in gardens. For example, in Japanese gardens, gravel is widely used to create dry landscape gardens. In modern-style gardens, gravel is also commonly used around water features in modern gardens as a filter layer or decorative layer. The application of gravel can also greatly enhance the visual effect of the garden.

[0003] Laying gravel on the soil of the garden can also achieve good improvement and treatment effects on the soil. The gravel above the soil can play a good role in moisturizing the soil, inhibit the growth of weeds, and keep the soil fertile. When laying gravel, it is necessary to screen and classify the gravel, remove oversized stones or undersized particles to ensure that the particle size of the gravel is uniform. This can not only improve the landscape effect but also ensure the flatness and stability of the laying. At the same time, when selecting gravel, it is also necessary to choose gravel without obvious edges and corners to prevent pedestrians or children from being injured. However, there is currently a lack of such a device for treating gravel, making it difficult to separate the gravel. Summary of the Invention

[0004] The purpose of the present invention is to provide a gravel treatment device for garden soil treatment to solve the problem that the garden gravel cannot be separated and treated at present.

[0005] The present invention is achieved through the following technical solutions:

[0006] A gravel treatment device for garden soil treatment includes a housing assembly, a centrifugal drum assembly, and a drive assembly. The centrifugal drum assembly includes a first centrifugal selection area, a second centrifugal selection area, and a third centrifugal selection area from bottom to top. Different centrifugal selection areas are provided with selection holes of different diameters, and the aperture of the selection holes increases sequentially from bottom to top. The housing assembly includes three discharge cavities, and the three discharge cavities are sequentially communicated with the three centrifugal selection areas. The three discharge cavities are the first discharge cavity, the second discharge cavity, and the third discharge cavity from inside to outside. The centrifugal drum assembly is also fixedly provided with a deceleration tube assembly outside the second centrifugal selection area. Each selection hole in the second centrifugal selection area is communicated with a deceleration tube. The deceleration tube includes a tube body and deceleration ribs provided on the inner wall of the tube body.

[0007] In a possible design, the inner diameter of the deceleration tube is greater than the inner diameter of the material selection holes in the second centrifugal material selection area. The deceleration tube is inclined with the end close to the material selection holes as the bottom end and the end far from the material selection holes as the high end. After the crushed stones enter the deceleration tube, since the inner diameter of the deceleration tube is greater than that of the material selection holes, it can be ensured that the crushed stones will not be stuck in the deceleration tube. The inclined design can ensure that the crushed stones always come into contact with the inner wall of the deceleration tube, enabling the sharp crushed stones to decelerate due to contact with the annular groove in the deceleration tube and thus be separated out.

[0008] In a possible design, a first interception ring is provided between the first centrifugal material selection area and the second centrifugal material selection area, and a second interception ring is provided between the second centrifugal material selection area and the third centrifugal material selection area. The first interception ring and the second interception ring are used to prevent too small crushed stones from entering an overly large centrifugal material selection area and falling out through an overly large hole.

[0009] In a possible design, the deceleration ribs are arranged uniformly along the axial direction of the tube body. The deceleration ribs are convex structures, and an annular groove is formed between adjacent two tube bodies.

[0010] In a possible design, the feed port of the second discharge cavity is at the same horizontal height as the second centrifugal material selection area. The feed port includes a plurality of sorting rings, and an annular feed port is provided between adjacent two sorting rings. Different-height multi-layer material selection holes are provided at the second centrifugal material selection area. An annular feed port of the same height is provided on the outside of the deceleration tube at the same layer height, and an annular spacer cavity is provided between the end of the deceleration tube and the annular feed port.

[0011] In a possible design, the side surface of the sorting ring facing the centrifugal drum assembly is an inclined surface, and adjacent two sorting rings are connected by a C-shaped connecting ring, and the C-shaped connecting ring is located in the second discharge cavity.

[0012] In a possible design, the housing assembly includes a first cylinder, a second cylinder, a third cylinder, and a fourth cylinder from the outside to the inside in sequence. The third discharge cavity is located between the first cylinder and the second cylinder, the second discharge cavity is located between the second cylinder and the third cylinder, the first discharge cavity is located between the third cylinder and the fourth cylinder. The housing assembly further includes a bottom baffle at the top, and a feeding port is opened on the bottom baffle, and a hopper-shaped baffle is fixedly provided at the feeding port.

[0013] In a possible design, the top of the third discharge cavity is communicated with the third centrifugal material selection area, the first discharge cavity is communicated with the first centrifugal material selection area. A communication port is also opened on the third cylinder, and a hopper-shaped plate is fixedly provided at the top of the third cylinder, and the top of the hopper-shaped plate is communicated with the annular spacer cavity.

[0014] In a possible design, a bottom flange is fixed to the bottom of the centrifugal drum assembly. The drive assembly includes a centrifugal drive motor. The body of the centrifugal drive motor is fixed to the housing assembly. The motor shaft of the centrifugal drive motor is fixed to the bottom flange. A thrust bearing is also provided between the bottom flange and the fourth cylinder.

[0015] In a possible design, an annular plate is further fixed to the top of the centrifugal drum assembly. At the same horizontal position as the annular plate, a plurality of guide wheel assemblies are provided. The guide wheel assemblies are evenly distributed in a ring on the inner wall of the housing assembly. The guide wheel assembly includes a support, a guide wheel, and an inner ring wall. The support is fixed to the housing assembly. The inner ring wall is fixed to the support. The guide wheel is rotatably provided on the inner ring wall. An annular trapezoidal groove is provided on the guide wheel. The annular plate contacts the guide wheel in the trapezoidal groove.

[0016] In a possible design, a material guiding base is further provided for guiding the three sorted gravels to three positions respectively for separate collection. The material guiding base includes an inner ring wall, an outer ring wall, a bottom plate, and a discharge hopper. The inner ring wall and the outer ring wall are coaxially arranged. The inner ring wall is located outside the outer ring wall. The bottom plate is inclined. The bottoms of the inner ring wall and the outer ring wall are both fixedly connected to the bottom plate. The discharge hopper is fixedly arranged at the lowest position of the bottom plate.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] 1. Through the high-speed rotation of the centrifugal drum and the design of multiple layers of screening meshes, the present invention realizes continuous and efficient screening of gravel in garden soil, greatly improving the screening efficiency.

Detailed Embodiments

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and do not limit the present invention.

[0031] Embodiment, such as Figures 1 to 4As shown in the figure, a gravel processing device for garden soil treatment includes a housing assembly 1, a centrifugal drum assembly 2, and a drive assembly. The drive assembly is used to control the rotation of the centrifugal drum assembly 2 to generate centrifugal force. The centrifugal drum assembly 2 successively includes a first centrifugal sorting area, a second centrifugal sorting area, and a third centrifugal sorting area from bottom to top. Sorting holes 201 with different diameters are provided in different centrifugal sorting areas, and the aperture of the sorting holes 201 increases successively from bottom to top. The housing assembly 1 includes three layers of discharge cavities, and the three layers of discharge cavities are successively communicated with the three centrifugal sorting areas. These three layers of discharge cavities are respectively the first discharge cavity 14, the second discharge cavity 13, and the third discharge cavity 12 from inside to outside. The fine gravel and the gravel with sharp edges are discharged from the first discharge cavity 14. The round stones that meet the gravel diameter are discharged from the second discharge cavity 13. The gravel with too large diameter is discharged from the third discharge cavity 12.

[0032] A deceleration tube 8 assembly is fixedly provided outside the second centrifugal sorting area of the centrifugal drum assembly 2. Each sorting hole 201 in the second centrifugal sorting area is communicated with a deceleration tube 8. The deceleration tube 8 includes a tube body 801 and deceleration ribs 802 provided on the inner wall of the tube body 801. The deceleration ribs 802 are uniformly arranged along the axial direction of the tube body 801. The deceleration ribs 802 are convex structures, and annular grooves are formed between adjacent tube bodies 801. After the gravel enters the inside of the deceleration tube 8, when the gravel moves in the deceleration tube 8, the sharp protrusions of the sharp gravel are easily inserted into the annular grooves, so that when the sharp gravel moves in the deceleration tube 8, the speed in the axial direction of the deceleration tube 8 is greatly reduced, while the smooth gravel does not have protrusions that can be inserted into the annular grooves, and the deceleration tube 8 only plays a role in decelerating the sharp and rough gravel, thereby further completing the sorting between the smooth gravel and the rough gravel under the same particle size.

[0033] Beneficially, the inner diameter of the deceleration tube 8 is larger than the inner diameter of the sorting hole 201 in the second centrifugal sorting area. The deceleration tube 8 is inclined with the end close to the sorting hole 201 as the bottom end and the end far from the sorting hole 201 as the high end. After the gravel enters the deceleration tube 8, because the inner diameter of the deceleration tube 8 is larger than the sorting hole 201, it can ensure that the gravel will not be stuck in the deceleration tube 8, and the inclined design can ensure that the gravel can always contact the inner wall of the deceleration tube 8, so that the sharp gravel can be decelerated due to contact with the annular groove in the deceleration tube 8 and thus be separated out.

[0034] In this embodiment, a first intercepting ring 11 is provided between the first centrifugal sorting area and the second centrifugal sorting area, and a second intercepting ring 10 is provided between the second centrifugal sorting area and the third centrifugal sorting area. The first intercepting ring 11 and the second intercepting ring 10 are used to prevent too small gravel from entering the too large centrifugal sorting area and falling out through the too large holes.

[0035] In this embodiment, the feed port of the second discharge chamber 13 is at the same horizontal height as the second centrifugal sorting area. The feed port includes a plurality of sorting rings 15. An annular feed port is provided between two adjacent sorting rings 15. At the second centrifugal sorting area, there are multi-layer sorting holes 201 at different heights. Similarly, the deceleration pipes 8 fixed to the sorting holes 201 are also at different heights at different layers. An annular feed port of the same height is provided outside the deceleration pipes 8 at the same layer. There is an annular spacer cavity between the end of the deceleration pipe 8 and the annular feed port. The sharp crushed stones decelerated by the deceleration pipe 8 will fall into the annular spacer cavity, while the smooth crushed stones can enter the annular feed port and finally enter the second discharge chamber 13.

[0036] Furthermore, one side of the sorting ring 15 facing the centrifugal drum assembly 2 is an inclined surface. Two adjacent sorting rings 15 are connected by a C-shaped connecting ring 16, and the C-shaped connecting ring 16 is located in the second discharge chamber 13.

[0037] In this embodiment, the housing assembly 1 sequentially includes a first cylinder 101, a second cylinder 102, a third cylinder 103, and a fourth cylinder 104 from the outside to the inside. The third discharge chamber 12 is located between the first cylinder 101 and the second cylinder 102. The second discharge chamber 13 is located between the second cylinder 102 and the third cylinder 103. The first discharge chamber 14 is located between the third cylinder 103 and the fourth cylinder 104. The housing assembly 1 further includes a bottom baffle 105 at the top. A feeding port is provided on the bottom baffle 105, and a bucket-shaped baffle is fixed at the feeding port, which can prevent the material from directly entering the third discharge chamber 12 during feeding and also facilitate the material to enter the centrifugal drum assembly 2 more smoothly.

[0038] In this embodiment, the top of the third discharge chamber 12 is communicated with the third centrifugal sorting area. The first discharge chamber 14 is communicated with the first centrifugal sorting area. A communication port is also provided on the third cylinder 103. A bucket-shaped plate is further fixed on the top of the third cylinder 103. The top of the bucket-shaped plate is communicated with the annular spacer cavity, and is used to converge the crushed stones falling into the annular spacer cavity into the first discharge chamber 14.

[0039] In this embodiment, a bottom flange 4 is fixed at the bottom of the centrifugal drum assembly 2. The drive assembly includes a centrifugal drive motor 3. The body of the centrifugal drive motor 3 is fixed to the housing assembly 1. The motor shaft of the centrifugal drive motor 3 is fixed to the bottom flange 4. The bottom flange 4 is also connected to the fourth cylinder 104 through a thrust bearing 5, and the thrust bearing 5 can make the rotation of the centrifugal drum assembly 2 smoother.

[0040] Furthermore, an annular plate 6 is fixed to the top of the centrifugal drum assembly 2. At the same horizontal height position as the annular plate 6, a plurality of guide wheel assemblies are provided. The guide wheel assemblies are evenly distributed in a ring on the inner wall of the housing assembly 1. The guide wheel assembly includes a support 7, a guide wheel 9, and an inner ring wall 17. The support 7 is fixed to the housing assembly 1. An inner ring wall 17 is fixed to the support 7. The guide wheel 9 is rotatably provided on the inner ring wall 17. An annular trapezoidal groove is provided on the guide wheel 9. The annular plate 6 contacts the guide wheel 9 in this trapezoidal groove. Thus, the annular plate 6 is supported by a plurality of the guide wheels 9, so that the centrifugal drum assembly 2 remains stable during rotation. The guide wheel 9 and the inner ring wall 17 are also connected by a bearing, so as to ensure the smoothness of the guide wheel 9 during rotation.

[0041] Furthermore, a material guiding base is also provided, which is used to guide the three sorted crushed stones to three positions respectively for separate collection. The material guiding base includes an inner ring wall 17, an outer ring wall 18, a bottom plate 19, and a discharge hopper 20. The inner ring wall 17 and the outer ring wall 18 are coaxially arranged. The inner ring wall 17 is located outside the outer ring wall 18. The bottom plate 19 is inclined. The bottoms of the inner ring wall 17 and the outer ring wall 18 are both fixedly connected to the bottom plate 19. The discharge hopper 20 is fixedly arranged at the lowest position of the bottom plate 19. The discharge hopper 20 is used for receiving materials. Refer to Figure 8 , in this embodiment, the crushed stones in the three discharge cavities can be respectively guided to three directions through the material guiding base, which is convenient for separate collection.
