Spiral stirring roller for mixing nutrient soil

Abstract

The utility model discloses a spiral stirring roller for mixing nutrient soil. The spiral stirring roller comprises a roller shaft, a spiral blade I and a spiral blade II, wherein the spiral blade I and the spiral blade II are sleeved on the roller shaft; the first spiral blade is fixedly connected to the roller shaft. The second spiral blade is also connected to the roller shaft in a sleeving mode and can slide in the axis direction of the roller shaft; by adjusting the position of the spiral blade II on the roll shaft, the width of the stirring channel is adjusted, so that different soil characteristics and stirring requirements can be met. When a wider stirring channel is needed, the spiral blade II is attached to the spiral blade I, so that the stirring space can be quickly expanded, and the stirring device is particularly effective for treating soil with higher humidity or larger particles, and ensures that the soil can be fully turned over and mixed. When a narrower stirring channel is needed, the stirring space can be reduced and the stirring strength can be increased only by moving the second spiral blade to the middle part of the spiral groove formed by the first spiral blade.

Description

Technical Field

[0001] This utility model relates to a spiral mixing roller for mixing nutrient soil, belonging to the field of spiral mixing technology. Background Technology

[0002] In the field of soil treatment, traditional mixing equipment often suffers from fixed mixing lane widths and poor adaptability, making it difficult to meet varying soil properties and mixing requirements. Especially for soils with high moisture content or large particles, traditional equipment often fails to achieve sufficient agitation and mixing, resulting in poor soil treatment outcomes. Furthermore, the soil's permeability and uniformity of mixing directly affect mixing efficiency and quality. An improperly designed mixing lane can easily lead to excessive soil compaction and clumping, further reducing the efficiency and quality of soil treatment. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a spiral mixing roller for mixing nutrient soil, which enables adjustment of the mixing channel width and can adapt to different soil characteristics and mixing requirements.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a spiral mixing roller for mixing nutrient soil, comprising:

[0005] Roller shaft;

[0006] Helical blade one and helical blade two are sleeved on the roller shaft;

[0007] in:

[0008] One of the spiral blades is fixedly connected to the roller shaft, and its position relative to the roller shaft cannot be moved;

[0009] The second spiral blade is also sleeved on the roller shaft and can slide along the axial direction of the roller shaft, so that an adjustable-width stirring channel is formed between the first spiral blade and the second spiral blade.

[0010] Preferably, a fixing frame is provided on one of the helical blades, the fixing frame comprising:

[0011] Multiple vertical rods are evenly distributed on the inner contour of the spiral blade.

[0012] Multiple fixing sleeves are fixed to the side wall of the roller shaft;

[0013] Each fixed sleeve is equipped with multiple connecting rods, which are respectively fixed to the corresponding vertical rod.

[0014] Preferably, multiple vertical rods are welded onto the inner contour of the spiral blade.

[0015] Preferably, it further includes a driving member for driving the spiral blades to slide, the driving member comprising:

[0016] A sliding sleeve, which is slidably connected to the side wall of the roller shaft;

[0017] A connecting ring, which is connected to a sliding sleeve via multiple connecting rods;

[0018] Multiple vertical rods are evenly distributed on the outer contour of the spiral blade, and the upper end of each vertical rod is fixedly connected to the side wall of the connecting ring.

[0019] Preferably, multiple vertical rods are welded onto the inner contour of the spiral blade.

[0020] Preferably, a groove is formed on the outer contour of the first spiral blade, and the second vertical rod is slidably connected to the groove.

[0021] Preferably, an annular groove is provided on the side wall of the sliding sleeve, and a push-pull block rotates in the annular groove. The push-pull block slides via an electric push rod.

[0022] Preferably, the surfaces of the first helical blade and the second helical blade are uniformly provided with mesh holes.

[0023] Preferably, the upper and lower ends of the roller are respectively provided with an upper connector and a lower connector, and a gear for connecting to an external motor is sleeved on the upper connector.

[0024] Preferably, spline grooves are provided on the side walls of both the upper connector and the lower connector.

[0025] Compared with existing technologies:

[0026] 1. This invention adjusts the width of the mixing channel by changing the position of the second spiral blade on the roller shaft, thus adapting to different soil properties and mixing requirements. When a wider mixing channel is needed, the second spiral blade is brought into contact with the first spiral blade to expand the mixing space. This is particularly effective for treating soils with high moisture content or large particles, ensuring thorough agitation and mixing. Conversely, when a narrower mixing channel is required, the second spiral blade is simply moved to the center of the spiral groove formed by the first spiral blade, reducing the mixing space and increasing the mixing intensity. This is highly advantageous for processing soils requiring higher mixing uniformity and smaller particle sizes.

[0027] 2. The mesh evenly opened on the surface of the spiral blades in this utility model not only promotes soil permeability and uniform mixing, but also helps to improve mixing efficiency and quality, so that the soil can maintain appropriate looseness during the mixing process, avoiding over-compaction and clumping.

[0045] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0046] Example 1

[0047] like Figures 1-7As shown in this embodiment, a spiral mixing roller for mixing nutrient soil is provided, including a roller shaft 1 and spiral blades 2 and 3 sleeved on the roller shaft 1. The surfaces of spiral blades 2 and 3 are uniformly provided with mesh holes. Spiral blade 2 is fixedly connected to the roller shaft 1 and its position is immovable relative to the roller shaft 1. Spiral blade 3 is also sleeved on the roller shaft 1 and can slide along the axial direction of the roller shaft 1, so that an adjustable-width mixing channel is formed between spiral blades 2 and 3 to adapt to different mixing needs.

[0048] Working process: During the mixing of the nutrient soil, firstly, based on the characteristics of the soil to be mixed (such as particle size, moisture content, etc.) and the required mixing intensity, the position of the second spiral blade 3 on the roller 1 is adjusted to form a mixing channel of suitable width. Then, through the rotation of the roller 1, the first spiral blade 2 and the second spiral blade 3 begin to drive the soil to mix. Driven by the spiral blades, the soil is continuously turned and mixed along the mixing channel, while simultaneously achieving aeration and uniform mixing through the mesh. Because the width of the mixing channel is adjustable, the mixing intensity can be flexibly adjusted according to actual needs to achieve the best mixing effect.

[0049] When a wider mixing channel is needed, adjust the position of the second spiral blade 3 on the roller 1 so that the second spiral blade 3 and the first spiral blade 2 are in close contact. At this time, a wider mixing channel can be obtained.

[0050] When a narrower mixing channel is required, adjust the position of the second spiral blade 3 on the roller 1 so that the second spiral blade 3 is moved to the middle position of the spiral groove formed by the first spiral blade 2 (e.g., Figure 1 As shown in the figure, a narrower mixing channel can be obtained at this time.

[0051] The upper and lower ends of the roller 1 are respectively provided with an upper connector 101 and a lower connector 102. The upper connector 101 is fitted with a gear 8 for transmission connection with an external motor. The external motor can be fixedly installed on the bucket for holding nutrient soil. The output shaft of the external motor is meshed with the gear 8. When the external motor is running, the output shaft of the external motor can drive the gear 8 to rotate, thereby realizing the rotation of the roller 1.

[0052] In addition, the lower connector 102 can be fitted with a bearing, which is installed at the bottom of the bucket used to hold the nutrient soil. The lower connector 102 is installed on the bearing to ensure the smooth rotation of the roller 1.

[0053] Both the upper connector 101 and the lower connector 102 have spline grooves 103 on their side walls.

[0054] Example 2

[0055] like Figures 4-5As shown, based on Embodiment 1, in order to fix the spiral blade 2 onto the roller shaft 1, this embodiment provides a fixing frame 4 on the spiral blade 2. The fixing frame 4 includes multiple vertical rods 401, which are evenly distributed on the inner contour of the spiral blade 2 by welding. Multiple fixing sleeves 402 are fixed on the side wall of the roller shaft 1. Each fixing sleeve 402 is provided with multiple connecting rods 403, which are respectively fixed on the corresponding vertical rods 401.

[0056] Work process:

[0057] The helical blade 2 is stably fixed to the roller 1 by adding a fixing frame 4. First, the fixing sleeve 402 is evenly fixed to the side wall of the roller 1. Then, the vertical rod 401 of the fixing frame 4 is evenly welded to the inner contour of the helical blade 2 using a welding process. Next, one end of the connecting rod 403 is fixed to the fixing sleeve 402, and the other end is fixed to the corresponding vertical rod 401, thereby achieving a firm connection between the helical blade 2 and the roller 1. During the mixing process, the helical blade 2 rotates under the drive of the roller 1 to mix the soil, while the fixing frame 4 ensures the stability and reliability of the helical blade 2, avoiding loosening or displacement during the mixing process, thus ensuring the mixing effect and soil quality.

[0058] Example 3

[0059] like Figures 1-3 As shown, based on the above embodiment, in order to drive the spiral blade 2 3 to slide along the axis of the roller shaft 1, this embodiment also includes a driving component 5 for driving the spiral blade 2 3 to slide. The driving component 5 includes a sliding sleeve 501, which is slidably connected to the side wall of the roller shaft 1. A connecting ring 502 is connected to the sliding sleeve 501 by a plurality of connecting rods 2 503. A plurality of vertical rods 2 504 are evenly distributed on the outer contour of the spiral blade 2 3 by welding process, and the upper end of each vertical rod 2 504 is fixedly connected to the side wall of the connecting ring 502.

[0060] A groove 201 is provided on the outer contour of the spiral blade 2, and the vertical rod 504 is slidably connected to the groove 201.

[0061] A ring groove 5011 is provided on the side wall of the sliding sleeve 501. A push-pull block 6 rotates in the ring groove 5011 and slides through an electric push rod 7.

[0062] like Figures 1-3 Figures 1-3As shown, there are two electric push rods 7, which operate synchronously. The output shaft ends of the two electric push rods 7 are respectively connected to both sides of the push-pull block 6. The cylinder of the electric push rod 7 can be fixed on the bucket used to hold the nutrient soil. As the electric push rod 7 operates, it drives the push-pull block 6 to slide on the roller shaft 1 with the sliding sleeve 501. At the same time, the push-pull block 6 rotates inside the annular groove 5011, which does not affect the synchronous rotation of the sliding sleeve 501 with the roller shaft 1.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
