Description

Technical Field

[0001] This utility model relates to the field of seedling nutrient soil production technology, specifically to a seedling nutrient soil crushing and screening machine. Background Technology

[0002] Nutrient soil for seedling cultivation provides trace elements to meet the needs of plants at different growth stages. To meet the diverse needs of different plants for different nutrient soils, it is necessary to crush and screen the soil.

[0003] In response to this, the utility model patent with authorization announcement number CN221360951U discloses an organic fertilizer screening device, including a box body, a filter screen for filtering organic fertilizer inside the box body, a feed pipe for transporting organic fertilizer through the top of the box body, an auxiliary roller for crushing and filtering organic fertilizer inside the box body, a hinge for assisting in replacing the filter screen on the outer wall of the box body, and multiple supports for supporting the overall device at the bottom of the box body.

[0004] This invention incorporates auxiliary rollers and a motor, among other components. During the screening of organic fertilizer, the auxiliary rollers assist in filtering the fertilizer on the filter screen, preventing waste during the screening process. However, this existing technology still has room for improvement.

[0005] The existing screening device can only perform one level of screening, meaning that the screened material has only one particle size range. However, in practical applications, different plants have different suitable growth environments for nutrient soil, and the same screening particle size cannot meet the diverse needs of different vegetation for nutrient soil particle size. When encountering this problem, the existing technology can only screen multiple times by changing different filter plates, which greatly reduces efficiency.

[0006] In view of this, improvements are needed to address the aforementioned deficiencies. Utility Model Content

[0007] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a seedling nutrient soil crushing and screening machine, which solves the problem that the lack of multi-stage screening in the existing technology makes it impossible to meet the diverse needs of different vegetation for nutrient soil.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a seedling nutrient soil crushing and screening machine, comprising: an upper cover fixedly mounted on a collection base, the upper cover having a feed inlet; a screening section fixedly mounted on the collection base, the screening section including a plurality of screens, the screening section also having a waste outlet, the screens having screening holes of different sizes; and a scraper rotatably mounted on the collection base, the scraper including a scraper rotatably mounted on the collection base, the scraper being attached to the screens; wherein, these screening sections together form a conical structure.

[0009] Optionally, the upper cover is provided with a crushing device, the crushing device having a discharge port connected to the inlet port, and the inlet port connected to the screening section.

[0010] Optionally, both the top cover and the screening section are fixed to the collection base via a central axis, and the corresponding screening section has a fixing hole for the central axis to pass through.

[0011] Optionally, the scraper further includes a rotating frame, and the scraper has multiple blades that are circumferentially and uniformly fixed on the rotating frame. The rotating frame, the upper cover, and the collection base are all rotatably connected.

[0012] Optionally, the collection base is provided with a number of partitions that correspond one-to-one with the screening section. Two adjacent partitions and the collection base form a collection cavity, and each collection cavity has a collection door.

[0013] Optionally, a scraper bar is provided at the position where the scraper blade is in contact with the screen, and the scraper bar has a plurality of arrayed slots and a protrusion is formed between two adjacent slots.

[0014] Optionally, a plug is provided on one side of the screening section, and a slot that mates with the plug is provided on the other side of the screening section, and two adjacent screening sections are connected together by the plug and the slot.

[0015] Optionally, a retaining ring is fixedly provided at the end of the scraper away from the rotating frame. The retaining ring is nested on the central shaft and rotatably connected to the central shaft.

[0016] The beneficial effects of this utility model are as follows: This invention features several screens with different aperture sizes, arranged together. By rotating a scraper, the seedling nutrient soil is sequentially scraped from one screen to another, thus achieving the sieving of nutrient soil with different particle sizes. This meets the diverse needs of modern vegetation for nutrient soil with different particle sizes, and eliminates the need for frequent replacement of screens with different aperture sizes, making it convenient and quick to use.

[0017] The sieve of this invention is assembled into a conical structure with an inclined surface. This allows the nutrient soil to roll and slide on the inclined surface when it falls, and to be sieved during the rolling and sliding process. This avoids the problem of nutrient soil accumulating in one place and reducing sieve efficiency, which is a problem with horizontally placed sieves. With the scraping of the scraper, the seedling nutrient soil crushing and screening machine of this invention has a more efficient sieve. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] As mentioned above, existing screening devices can only perform one level of screening, meaning that the screened material has only one particle size range. However, in practical applications, different plants have different suitable growth environments for nutrient soil, and the same screening particle size cannot meet the diverse needs of different vegetation for nutrient soil particle size. When encountering this problem, existing technologies can only screen multiple times by changing different filter plates, which greatly reduces efficiency.

[0029] Therefore, to address the aforementioned shortcomings, this invention proposes a crushing and screening device that can be applied to the crushing and screening of seedling nutrient soil, thereby achieving multi-stage screening and solving the problems in the prior art. This invention is achieved through the following means.

[0030] Example 1: Please refer to the instruction manual appendix. Figures 1 to 4 As shown in the figure, this utility model provides a seedling nutrient soil crushing and screening machine, which includes an upper cover 1, a screening section 2, a scraper section 3, and a collection base 4. The upper cover 1 and the collection base 4 are arranged vertically, connected by a central shaft 5. The screening section 2 is located between the upper cover 1 and the collection base 4, and correspondingly, the screening section 2 has a fixing hole 23 for the central shaft 5 to pass through. The fixing hole 23 is also fixed to the screening section 2. There are four screening sections 2. One screening section 2 has a waste outlet 22, and the remaining three screening sections 2 have screens 21. The screening holes on each screen 21 are of the same size and evenly distributed, but the screen hole sizes of different screens 21 are different. The screening sections 2 are arranged sequentially in ascending order of the size of the screening holes on the screens 21. Including the screening section 2 with the waste outlet 22, the four screening sections 2 together form a conical structure.

[0031] In this first embodiment, the upper cover 1 is provided with an inlet 11 for adding crushed seedling nutrient soil. A crushing device is also provided outside the inlet 11. This crushing device has a discharge port connected to the inlet 11, which is also connected to the screening section 2. The screen 21 on the screening section 2, which is connected to the inlet 11, has the smallest aperture. When the crushed seedling nutrient soil is added from the discharge port of the crushing device into the inlet 11, the seedling nutrient soil first falls onto the screen 21 with the smallest aperture. Then, it is scraped by the scraper 3, and the seedling nutrient soil passes through different screens 21 in ascending order of aperture size, thus screening seedling nutrient soil of different particle sizes. Finally, the seedling nutrient soil that cannot be screened falls from the waste port 22 and is collected, recycled, or disposed of.

[0032] In this first embodiment, the scraper 3 includes four scrapers 32, which are attached to the screen 21. The scrapers 32 rotate on the screen 21 to remove the seedling nutrient soil. The four scrapers 32 are arranged around the four screens 21, and a rotating frame 31 is fixed to the side of the scraper 32 away from the screen 21. The rotating frame 31 is also located between the upper cover 1 and the collecting base 4, and is rotatably connected to the upper cover 1 and the collecting base 4 (e.g., rotary connection, bearing connection, ball bearing connection). In use, an additional drive mechanism drives the rotating frame 31 to rotate, which in turn drives the scrapers 32 to scrape on the screen 21.

[0033] In this first embodiment, a preferred implementation is as follows: the driving mechanism includes a gear ring fixed to the periphery of the rotating frame 31, with a gear meshing on the gear ring. The gear is rotatably connected to the outer wall of the collecting base 4 and is driven to rotate by a motor. The motor is also fixed to the outer wall of the collecting base 4. The motor, as a power source, enables the gear to drive the gear ring to rotate, thereby causing the rotating frame 31 to rotate.

[0034] In this first embodiment, the collection base 4 is equipped with four partitions 41, the positions of which correspond one-to-one with the positions of the screening sections 2. That is, the partitions 41 are located at the junctions of two adjacent screening sections 2. The partitions 41 divide the collection base 4 into four collection chambers, each corresponding to one screening section 2. The seedling nutrient soil screened from the screening section 2 will enter the corresponding collection chamber. Each collection chamber has a collection door 42, which can be opened to retrieve the seedling nutrient soil with different particle sizes that have been sorted and collected.

[0035] Therefore, in the specific implementation of this embodiment, the seedling nutrient soil is first crushed by a crushing device, and then the crushed seedling nutrient soil is conveyed through the discharge port of the crushing device to the screen 21 with the smallest screening hole through the feed port 11. At this time, some seedling nutrient soil with smaller particle size will pass through the screen 21 and enter the collection chamber. The remaining seedling nutrient soil that does not pass through the screen 21 is retained on the inclined surface of the screen 21. Then, the drive motor rotates, and the motor drives the gear meshing gear ring to rotate. During the rotation of the gear ring, the rotating frame 31 rotates, thereby driving the scraper 32 to rotate. During the rotation process, the scraper 32 scrapes the seedling nutrient soil retained on the inclined surface of the screen 21 in sequence to another screen 21 with a larger screening hole. At this time, some seedling nutrient soil passes through. The rest that does not pass through continues to be scraped by the rotation of the scraper 32, and the cycle repeats. After all the seedling nutrient soil has passed through the sieves 21, any remaining seedling nutrient soil will be scraped into the waste inlet 22 by the scraper 32 for further collection or processing.

[0036] This first embodiment achieves the classification and screening of seedling nutrient soil with different pore sizes after crushing through the above method, thus meeting diverse seedling needs.

[0037] Example 2: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figure 5 As shown in Embodiment 2, a scraper strip 321 is provided at the position where the scraper 32 and the screen 21 are in contact. The scraper strip 321 has a plurality of arrayed slots 322, and a protrusion is formed between two adjacent slots 322. The protrusion is made of a deformable material (e.g., silicone or plastic). During the process of the scraper 32 scraping the screen 21, the scraper strip 321 can act as a buffer, so that the scraper 32 can scrape efficiently while reducing wear between it and the screen 21.

[0038] Example 3: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Three. For example... Figure 6 As shown in Embodiment 3, one side of the screening unit 2 is provided with an insert block 24, and the other side is provided with a slot 25 for use with the insert block 24. Two adjacent screening units 2 are connected together by inserting the insert block 24 and the slot 25. This allows the insert block 24 and the slot 25 to be plugged in and out as needed, making the screening unit 2 easy to disassemble and replace.

[0039] Example 4: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Four. For example... Figure 7 As shown in Embodiment 4, a fixing ring 323 is fixedly provided at the end of the scraper 32 away from the rotating frame 31, and four fixing rings 323 are gathered together to form a complete ring. Through this ring, the fixing rings 323 are nested on the central shaft 5 and rotatably connected to it. Therefore, in use, the scraper 32 is limited by both the fixing rings 323 and the rotating frame 31, so that it will not deviate during rotation.

[0040] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
