Description

Technical Field

[0001] This utility model relates to the field of planting soil equipment, specifically to a granulation device for planting soil. Background Technology

[0002] Existing planting soil often requires the addition of various additives during mixing to ensure its loose physical properties while providing the nutrients needed for plant growth. Therefore, its overall structure is generally loose. Since the nutrients in the soil are directly mixed in during the mixing process, when watering is carried out in the early stages of use, nutrients are easily leached out and accumulate at the bottom of the soil. Alternatively, excessive watering may cause the leached nutrients to be washed away, resulting in nutrient loss. Therefore, how to ensure the retention and slow release of nutrients in the planting soil during the preparation process is a problem that needs to be solved. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a granulation device for planting soil with high pelleting rate, effectively improving the upward turning effect of fine particles at the bottom, granulating the planting soil, and locking in its nutrients to achieve a slow-release effect.

[0004] To address the above problems, the following technical solution is provided: a granulation device for planting soil, comprising a frame, a swing arm that can swing relative to the frame, a driving device and a granulation disc on the swing arm, the granulation disc comprising a disc bottom and a disc wall, the rotation axis of the granulation disc being inclined relative to the ground, the upper surface of the disc bottom and the inner wall of the disc wall being provided with an anti-stick and corrosion-resistant layer, a plurality of first capture grooves concentrically arrayed on the surface of the anti-stick and corrosion-resistant layer corresponding to the surface of the upper surface of the disc bottom being provided, and an upwardly convex first capture protrusion forming between adjacent first capture grooves, and a plurality of second capture grooves spaced apart along the axial direction of the disc wall corresponding to the inner surface of the anti-stick and corrosion-resistant layer of the disc wall being provided, and an inwardly convex second capture protrusion forming between adjacent second capture grooves.

[0005] In the above structure, the granular planting soil uses rice husks soaked in nutrient solution as the core for pelleting. This serves as a carrier of nutrients and facilitates subsequent degradation. Since rice husks often vary in size, traditional disc pelletizers experience less friction between the material and the disc bottom and walls during turning. Additionally, small rice husk particles tend to slip when clustered at the bottom, affecting turning efficiency. This results in a lower pelleting rate for small rice husk particles due to low turning efficiency. Larger rice husks, on the other hand, have greater friction and are more easily turned, leading to higher pelleting efficiency. This rapid size difference between the particles results in a higher return ratio. By setting up a first capturing groove, a first capturing protrusion, a second capturing groove, and a second capturing protrusion, small rice husk particles are more easily lifted during turning compared to contact with a flat surface, thus improving pelleting efficiency and reducing the return ratio. Simultaneously, the anti-stick and corrosion-resistant layer provides better anti-stick and corrosion resistance compared to traditional smooth surfaces, effectively extending service life and preventing clumping.

[0006] The present invention is further configured such that the bottom cross-section of the first capture groove is semi-circular or arc-shaped, the cross-section of the first capture protrusion is semi-circular or arc-shaped, and the arc of the bottom of the first capture groove is tangentially transitioned to the arc of the cross-section of the first capture protrusion; the bottom cross-section of the second capture groove is semi-circular or arc-shaped, the cross-section of the second capture protrusion is semi-circular or arc-shaped, and the arc of the bottom of the second capture groove is tangentially transitioned to the arc of the cross-section of the second capture protrusion.

[0007] In the above structure, each cross-section is preferably semi-circular.

[0008] The present invention is further configured such that the anti-stick and corrosion-resistant layer is made of polytetrafluoroethylene.

[0009] In the above structure, polytetrafluoroethylene material has an anti-sticking effect while also having strong corrosion resistance and can effectively avoid chemical reactions.

[0010] The present invention is further configured such that the disc wall is provided with a feeding window opened in the height direction of its side wall, and an openable feeding door is hinged to one side of the feeding window, and a locking mechanism is provided on the side of the feeding window and the feeding door away from each other.

[0011] In the above structure, the feeding gate can be opened to feed the pelleted planting soil. The feeding gate and the feeding window are locked together by a locking mechanism.

[0012] The present invention is further configured such that the anti-stick and corrosion-resistant layer on the inner wall of the disc wall, corresponding to the position of the inner wall of the feeding gate, is adhered and fixed to the inner wall of the feeding gate.

[0013] In the above structure, the anti-stick and corrosion-resistant layer is fixed to the inner wall of the feeding gate by adhesive, screw or snap-fit; the anti-stick and corrosion-resistant layer can be divided into multiple pieces and laid in the granulation tray.

[0014] The present invention is further configured such that the locking mechanism includes a first locking sleeve located on the side of the unloading gate and a second locking sleeve located on the side of the unloading window. When the unloading gate is closed, the first locking sleeve and the second locking sleeve are concentric with each other and locked by a pin.

[0015] The above structure has the advantages of being simple, stable and reliable.

[0016] The present invention is further configured such that the height between the bottom of the first capture groove and the top of the first capture protrusion is equal to the width of the first capture groove and the width of the first capture protrusion; and the height between the bottom of the second capture groove and the top of the second capture protrusion is equal to the width of the second capture groove and the width of the second capture protrusion.

[0017] In the above structure, the height between the bottom of the first capture groove and the top of the first capture protrusion can be set to be less than the width of the first capture groove and the width of the first capture protrusion as needed; the height between the bottom of the second capture groove and the top of the second capture protrusion can be set to be less than the width of the second capture groove and the width of the second capture protrusion as needed.

[0018] The present invention is further configured such that the height between the bottom of the first capture groove and the top of the first capture protrusion is 3mm-10mm, and the width of the first capture groove and the width of the first capture protrusion are 3mm-10mm; the height between the bottom of the second capture groove and the top of the second capture protrusion is 3mm-10mm, and the width of the second capture groove and the width of the second capture protrusion are 3mm-10mm.

[0019] In the above structure, the uniform thickness is preferably 8mm.

[0020] The present invention is further configured such that the rack includes a scraper rack located above the granulation tray opening, the scraper rack being provided with a scraper, the scraper being located in the range of 10 o'clock to 3 o'clock position in the circumferential direction of the granulation tray.

[0021] In the above structure, the scraper is used to adjust the falling direction and speed of the material during the turning process.

[0022] The beneficial effects of this invention are as follows: The granular planting soil uses rice husks soaked in nutrient solution as the core for pelleting. This serves as a carrier of nutrients and facilitates subsequent degradation. Since rice husks often vary in size, traditional disc pelletizers experience less friction between the material and the disc bottom and walls during turning. Furthermore, small rice husk particles tend to slip when clustered at the bottom, affecting turning efficiency. This results in a lower pelleting rate for small rice husk particles due to low turning efficiency. Larger rice husks, on the other hand, have greater friction and are more easily turned, leading to higher pelleting efficiency. This rapid increase in size difference between particles results in a higher return rate. By setting up a first capturing groove, a first capturing protrusion, a second capturing groove, and a second capturing protrusion, small rice husk particles are more easily lifted during turning compared to contact with a flat surface, thus improving pelleting efficiency and reducing the return rate. Simultaneously, the anti-stick and corrosion-resistant layer provides better anti-stick and corrosion resistance compared to traditional smooth surfaces, effectively extending service life and preventing clumping.

Detailed Implementation

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] refer to Figures 1 to 6 ,like Figures 1 to 6 The illustrated granulation device for planting soil includes a frame 10. The frame 10 is equipped with a swing frame 11 that can swing relative to the frame 10. The swing frame 11 is equipped with a drive device 12 and a granulation disc 20. The granulation disc 20 includes a disc bottom 21 and a disc wall 22. The rotation axis of the granulation disc 20 is inclined relative to the ground. The upper surface of the disc bottom 21 and the inner wall of the disc wall 22 are provided with an anti-stick and corrosion-resistant layer 30. A plurality of first capture grooves 31 are arranged concentrically on the surface of the anti-stick and corrosion-resistant layer 30 on the upper surface of the disc bottom 21. An upwardly convex first capture protrusion 32 is formed between adjacent first capture grooves 31. A plurality of second capture grooves 33 are arranged at intervals along the axial direction of the disc wall 22 on the inner surface of the anti-stick and corrosion-resistant layer 30 on the inner wall of the disc wall 22. An inwardly convex second capture protrusion 34 is formed between adjacent second capture grooves 33.

[0032] In the above structure, the granular planting soil uses rice husks soaked in nutrient solution as the core for pelleting. This serves as a carrier of nutrients and facilitates subsequent degradation. However, because rice husks often vary in size, traditional disc pelletizers experience relatively low friction between the material and the disc bottom 21 and disc wall 22 during turning. Furthermore, small rice husk particles tend to slip when accumulating at the bottom, affecting turning efficiency. This results in a lower pelleting rate for small rice husk particles due to low turning efficiency. Larger rice husks, on the other hand, have greater friction than smaller particles and are more easily pelletized. The material easily enters a turning state, resulting in higher pelleting efficiency. However, this leads to a rapid increase in size difference between the pellets, resulting in a higher return ratio. By setting the first capturing groove 31, the first capturing protrusion 32, the second capturing groove 33, and the second capturing protrusion 34, the fine rice husk particles are more easily lifted by the turning process compared to contact with a flat surface, thereby improving the pelleting efficiency of the fine rice husk particles and reducing the return ratio. At the same time, the anti-stick and corrosion-resistant layer 30 has certain anti-stick and corrosion resistance compared to the traditional smooth surface structure, which can effectively improve the service life and prevent clumping.

[0033] In this embodiment, the bottom cross-section of the first capture groove 31 is semi-circular or arc-shaped, the cross-section of the first capture protrusion 32 is semi-circular or arc-shaped, and the arc of the bottom of the first capture groove 31 is tangentially transitioned to the arc of the cross-section of the first capture protrusion 32; the bottom cross-section of the second capture groove 33 is semi-circular or arc-shaped, the cross-section of the second capture protrusion 34 is semi-circular or arc-shaped, and the arc of the bottom of the second capture groove 33 is tangentially transitioned to the arc of the cross-section of the second capture protrusion 34.

[0034] In the above structure, each cross-section is preferably semi-circular.

[0035] In this embodiment, the anti-stick and corrosion-resistant layer 30 is made of polytetrafluoroethylene.

[0036] In the above structure, polytetrafluoroethylene material has an anti-sticking effect while also having strong corrosion resistance and can effectively avoid chemical reactions.

[0037] In this embodiment, the disc wall 22 is provided with a feeding window 221 opened in the height direction of its side wall. A feed door 23 that can be opened is hinged to one side of the feeding window 221. A locking mechanism 24 is provided on the side of the feeding window 221 and the feed door 23 away from each other.

[0038] In the above structure, after the feeding gate 23 is opened, the pellet planting soil that has been formed into balls can be fed. The feeding gate 23 and the feeding window 221 are locked together by the locking mechanism 24.

[0039] In this embodiment, the anti-stick and corrosion-resistant layer 30 on the inner wall of the disc wall 22, corresponding to the position of the inner wall of the feeding gate 23, is attached and fixed to the inner wall of the feeding gate 23.

[0040] In the above structure, the anti-stick and corrosion-resistant layer 30 is fixed to the inner wall of the feeding gate 23 by adhesive, screw or snap-fit; the anti-stick and corrosion-resistant layer 30 can be divided into multiple pieces and laid in the granulation tray 20.

[0041] In this embodiment, the locking mechanism 24 includes a first locking sleeve 241 located on the side of the unloading gate 23 and a second locking sleeve 242 located on the side of the unloading window 221. When the unloading gate 23 is closed, the first locking sleeve 241 and the second locking sleeve 242 are concentric and locked by a pin 243.

[0042] The above structure has the advantages of being simple, stable and reliable.

[0043] In this embodiment, the height L1 between the bottom of the first capture groove 31 and the top of the first capture protrusion 32 is equal to the width H1 of the first capture groove 31 and the width H2 of the first capture protrusion 32; the height L2 between the bottom of the second capture groove 33 and the top of the second capture protrusion 34 is equal to the width H3 of the second capture groove 33 and the width H4 of the second capture protrusion 34.

[0044] In the above structure, the height L1 between the bottom of the first capture groove 31 and the top of the first capture protrusion 32 can be set as needed to be less than the width H1 of the first capture groove 31 and the width H2 of the first capture protrusion 32; the height L2 between the bottom of the second capture groove 33 and the top of the second capture protrusion 34 can be set as needed to be less than the width H3 of the second capture groove 33 and the width H4 of the second capture protrusion 34.

[0045] In this embodiment, the height L1 between the bottom of the first capture groove 31 and the top of the first capture protrusion 32 is 3mm-10mm, and the width H1 of the first capture groove 31 and the width H2 of the first capture protrusion 32 are 3mm-10mm; the height L2 between the bottom of the second capture groove 33 and the top of the second capture protrusion 34 is 3mm-10mm, and the width H3 of the second capture groove 33 and the width H4 of the second capture protrusion 34 are 3mm-10mm.

[0046] In the above structure, the uniform thickness is preferably 8mm.

[0047] In this embodiment, the rack 11 includes a scraper rack 13 located above the opening of the granulation tray 20. The scraper rack 13 is provided with a scraper 14, which is located in the 10 o'clock to 3 o'clock position range in the circumferential direction of the granulation tray 20.

[0048] In the above structure, the scraper 14 is used to adjust the falling direction and speed of the material during the turning process.

[0049] The beneficial effects of this invention are as follows: The granular planting soil uses rice husks soaked in nutrient solution as the core for pelleting. This serves as a carrier of nutrients and facilitates subsequent degradation. Because rice husks often vary in size, traditional disc pelletizers experience relatively low friction between the material and the disc bottom 21 and disc wall 22 during turning. Furthermore, small rice husk particles tend to slip when accumulating at the bottom, affecting turning efficiency. Consequently, the pelleting rate of small rice husk particles decreases due to low turning efficiency. Larger rice husk particles, on the other hand, have greater friction than smaller ones. It is easier to enter the turning state, resulting in higher pelleting efficiency. However, the size difference between the pellets will be quickly widened, leading to a higher return ratio. By setting the first capturing groove 31, the first capturing protrusion 32, the second capturing groove 33, and the second capturing protrusion 34, the small rice husk particles are more easily picked up by the turning process compared to contact with a flat surface, thereby improving the pelleting efficiency of the small rice husk particles and reducing the return ratio. At the same time, the anti-stick and corrosion-resistant layer 30 has a certain degree of anti-stick and corrosion resistance compared to the traditional smooth structure, which can effectively improve the service life and avoid the occurrence of clumping.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
