Description

Technical Field

[0001] This utility model relates to a seed mixing machine, and more particularly to a crop seed mixing machine. Background Technology

[0002] Seed treatment is an important pretreatment step in agricultural production. By uniformly mixing seeds with liquid pesticides, it can effectively prevent and control pests and diseases, and improve seed germination rate and stress resistance. Currently, common seed treatment equipment typically includes a fixed seed treatment drum and a stirring mechanism installed inside the drum. The stirring mechanism rotates under the drive of a drive unit, turning and mixing the seeds and pesticides inside the drum.

[0003] However, in practice, especially when using highly viscous liquid agents, the mixture of seeds and agents easily adheres to the inner wall of the seed mixing drum. As mixing continues, this adhered material accumulates and thickens, not only reducing the effective mixing space but also causing uneven distribution of the agent among the seed population because this material cannot participate in normal tumbling and mixing.

[0004] Furthermore, in the discharge stage after mixing, most equipment requires manual scooping from the cylinder opening or gravity discharge from the bottom gate. The former is labor-intensive and inefficient; the latter is prone to blockage and residue at the gate and has a relatively complex structure. Utility Model Content

[0005] The main objective of this invention is to provide a crop seed coating machine to solve the problems raised in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a crop seed mixing machine is provided, comprising a support frame and a mixing cylinder disposed on the support frame, wherein liquid agent and seeds are injected into the mixing cylinder through a top opening, the mixing cylinder is provided with a mixing component, the mixing component is provided with a scraping component, the mixing component is rotatable within the mixing cylinder, and the scraping component is used to scrape off seed material adhering to the mixing cylinder. The support is equipped with a driving component, which is used to drive the seed mixing cylinder to rotate and pour out the mixed seeds.

[0007] Furthermore, the seed mixing component includes a rotating shaft rotatably disposed at the center of the seed mixing cylinder, and several seed mixing blades are fixedly connected in a circular array on the rotating shaft.

[0008] Furthermore, the scraping component includes a connecting rod fixedly connected to the outer wall of the upper end of the rotating shaft, and a vertical scraper fixedly connected to the connecting rod, with a horizontal scraper fixedly connected to one end of the vertical scraper.

[0009] Furthermore, the connecting rod is arranged perpendicularly to the vertical scraper, and the vertical scraper is in close contact with the inner wall of the seed mixing cylinder, while the horizontal scraper is in close contact with the bottom wall of the seed mixing cylinder.

[0010] Furthermore, a first motor is fixedly installed at the bottom of the seed mixing cylinder, and the output shaft of the first motor is fixedly connected to the rotating shaft.

[0011] Furthermore, the support includes a horizontal plate and vertical plates fixedly disposed at both ends of the horizontal plate, and the seed mixing cylinder is disposed between the two vertical plates.

[0012] Furthermore, two connecting shafts are symmetrically fixedly arranged on the outer wall of the seed mixing cylinder, and the two connecting shafts are respectively rotatably arranged in two vertical plates. The driving component includes a second motor fixedly arranged on one side of one of the vertical plates, and the second motor is fixedly connected to the connecting shaft of the seed mixing cylinder on the corresponding side.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this crop seed mixing machine, while the mixing blades rotate to mix, the vertical scraper rotates synchronously with the rotating shaft and always maintains close contact with the inner wall of the mixing cylinder. This allows the seeds and agents adhering to the cylinder wall to be scraped off in real time and returned to the mixing area to participate in the mixing; effectively preventing the accumulation of materials on the cylinder wall.

[0014] 2. In this crop seed mixing machine, the entire mixing cylinder is driven to rotate and tilt the material by a second motor, making the discharge process more labor-saving and efficient, and improving the overall ease of operation of the equipment. Attached Figure Description

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] This embodiment provides a crop seed dressing machine, including a support 1 and a dressing cylinder 2 disposed on the support 1. Liquid agent and seeds are put into the dressing cylinder 2 through the top opening. The dressing cylinder 2 is provided with a dressing component, and the dressing component is provided with a scraping component. The dressing component can rotate inside the dressing cylinder 2, and the scraping component is used to scrape off the seed material adhering to the dressing cylinder 2. The support 1 is equipped with a driving component, which is used to drive the seed mixing cylinder 2 to rotate and pour out the mixed seeds.

[0019] like Figure 1 and Figure 2 As shown, the seed mixing component includes a rotating shaft 3 rotatably disposed at the center of the seed mixing cylinder 2, and a plurality of seed mixing blades 31 are fixedly connected in a ring array on the rotating shaft 3.

[0020] like Figure 1 and Figure 2 As shown, the scraping component includes a connecting rod 41 fixedly connected to the upper outer wall of the rotating shaft 3, and a vertical scraper 42 fixedly connected to the connecting rod 41. One end of the vertical scraper 42 is fixedly connected to a horizontal scraper 43 perpendicular to it.

[0021] like Figure 1 and Figure 2 As shown, the connecting rod 41 is perpendicular to the vertical scraper 42, and the vertical scraper 42 is in close contact with the inner wall of the seed mixing cylinder 2, while the horizontal scraper 43 is in close contact with the bottom wall of the seed mixing cylinder 2.

[0022] like Figure 1 and Figure 2 As shown, a first motor 5 is fixedly installed at the bottom of the seed mixing cylinder 2. The output shaft of the first motor 5 passes through the seed mixing cylinder 2 and is fixedly connected to the rotating shaft 3. After the seeds and liquid agent are put into the seed mixing cylinder 2, the first motor 5 is started to drive the rotating shaft 3 to rotate. The seed mixing blades 31 rotate synchronously, turning the seeds in the seed mixing cylinder 2 and making the liquid agent fully coat the seed surface. During this process, the vertical scraper 42 and the horizontal scraper 43 rotate along the inner wall of the seed mixing cylinder 2 to scrape off the seeds and liquid agent adhering to the inner wall of the seed mixing cylinder 2, so as to avoid accumulation and adhesion on the inner wall of the seed mixing cylinder 2 and affect the seed mixing effect.

[0023] like Figure 1 and Figure 2As shown, the support 1 includes a horizontal plate 11 and vertical plates 12 fixedly disposed at both ends of the horizontal plate 11, and the seed mixing cylinder 2 is disposed between the two vertical plates 12.

[0024] like Figure 1 and Figure 2 As shown, two connecting shafts are symmetrically fixed on the outer wall of the seed mixing cylinder 2. The two connecting shafts are respectively rotatably installed in the two vertical plates 12. The driving component includes a second motor 6 fixedly installed on one side of one of the vertical plates 12. The second motor 6 is fixedly connected to the connecting shaft of the seed mixing cylinder 2 on the corresponding side. After the seed mixing is completed, the second motor 6 is started to drive the seed mixing cylinder 2 to rotate around the axis of its connecting shaft, so that the seeds can be poured out for use.

[0025] It is worth noting that a U-shaped mounting frame is fixedly installed at the bottom of the seed mixing cylinder 2, and the first motor 5 is installed inside the mounting frame to provide support and protection, so as to prevent the first motor 5 from falling off and being damaged due to its own weight during the rotation and tilting of the seed mixing cylinder 2.

[0026] In practical use, the seeds and liquid agent to be treated are put into the mixing cylinder 2 through the top opening. The first motor 5 is turned on, driving the rotating shaft 3 to rotate the mixing blades 31. The mixing blades 31 thoroughly stir and tumble the seeds and agent, so that the agent is evenly coated on the seed surface. At the same time, the vertical scraper 42 and the horizontal scraper 43 fixed to the upper end of the rotating shaft 3 rotate synchronously with the shaft, closely adhering to the inner wall of the mixing cylinder 2, continuously scraping off the seed and agent mixture that splashes and adheres to the cylinder wall during the stirring process, returning it to the core stirring area. After stirring for a certain period of time, the agent has evenly coated the seeds, and the mixing process ends. Then, the second motor 6 is started, driving the mixing cylinder 2 to rotate and tilt around its connecting shaft. At the same time, the first motor 5 is started again, driving the connecting rod 41, the vertical scraper 42, and the horizontal scraper 43 to rotate. While the material is falling, the seeds adhering to the annular side wall and bottom wall of the mixing cylinder 2 are scraped off, thus achieving more convenient, faster, and more thorough seed feeding.
