For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1-Figure 7 As shown, an embodiment of the present invention provides a small-scale microbial agent seed mixing device, comprising a support 1, a first bracket 11 being fixedly connected to the support 1, a collar 3 being installed on the inner side of the first bracket 11, a rotating drum 2 being rotatably installed in the collar 3, the central axis of the rotating drum 2 being arranged horizontally, a mixing chamber 21 being provided in the rotating drum 2, a material port 22 connected to the mixing chamber 21 being provided at one end of the rotating drum 2, and the rotating drum 2 being driven to rotate around its own central axis.

[0031] Specifically, the support 1 is the supporting structure of the seed mixing device, and the upper surface of the support seat is fixedly connected to the first bracket 11. Preferably, the first bracket 11 is U-shaped, and a ring 3 is installed on the inner side thereof. The central axis of the ring 3 is arranged horizontally, and a rotating drum 2 is rotatably installed inside the ring 3. A mixing chamber 21 is provided in the rotating drum 2, and a material port 22 connected to the mixing chamber 21 is opened at one end of the rotating drum 2. In addition, the seed mixing device also includes a driving member for driving the rotating drum 2 to rotate. Optionally, the driving member is a motor installed on the first bracket 11, and the output shaft of the motor is transmission-connected to the rotating drum 2. This is the existing technology and can be directly applied. When the rotation is driven to rotate around its own central axis, the seeds put into the mixing chamber 21 from the material port 22 are continuously rolled and contacted with the biological agent under the drive of the rotating drum 2, so that the seed epidermis can be fully covered with the biological agent.

[0032] The microbial agent seed mixing device proposed in the present invention mixes seeds and biological agents by rotating the drum 2. The mixing method is gentle and is not likely to cause significant damage to the seed epidermis. Moreover, the materials in various places in the drum 2 can be rolled under the drive of the drum 2, which makes the mixing of seeds and biological agents more comprehensive.

[0033] Furthermore, a rotating shaft 31 is fixedly connected to the outer wall of the collar 3 along its own axial direction. The rotating shaft 31 is rotatably connected to the first bracket 11 . The first bracket 11 is also provided with a driving part that drives the drum 2 to rotate about the central axis of the rotating shaft 31 .

[0034] Preferably, one end of the drum 2 where the material outlet 22 is provided is funnel-shaped.

[0035] Optionally, the driving unit includes an electric push rod 111 rotatably mounted on the first bracket 11 , one end of the rotating drum 2 is rotatably connected to the adjusting ring 4 , and an output end of the electric push rod 111 is rotatably connected to the adjusting ring 4 .

[0036] Specifically, in the above embodiment, after the seeds and the biological agent are mixed, it is not easy to remove the seeds coated with the biological agent from the drum 2. In this embodiment, the outer wall of the ring 3 is fixed with a rotating shaft 31, and the rotating shaft 31 is provided with two groups and symmetrically arranged on both sides of the drum 2, that is, the drum 2 is Figure 3 The upper and lower sides of the figure are fixed with rotating shafts 31, and both sets of rotating shafts 31 are rotatably connected to the first bracket 11, so that the drum 2 can rotate around its own central axis and the central axis of the rotating shaft 31, and further the end of the drum 2 with the material port 22 is set into a funnel shape, as shown in FIG. Figures 1 to 4 As shown, after the seeds and the biological inoculant are mixed, the drum 2 is rotated so that the material port 22 can be tilted downward, cooperating with the funnel-shaped portion of the drum 2, so as to facilitate the discharge of the seeds coated with the biological inoculant; in addition, the first bracket 11 is further provided with an electric push rod 111 for driving the drum 2 to rotate around the central axis of the rotating shaft 31. One end of the electric push rod 111 is hinged to the first bracket 11. In order to facilitate the connection between the electric push rod 111 and the drum 2 without affecting the rotation of the drum 2 around its own central axis, an adjusting ring 4 is provided on the funnel-shaped end of the drum 2. Figures 1 to 3 As shown, the adjustment ring 4 can rotate relative to the drum 2, and the output end of the electric push rod 111 is rotatably connected to the outer wall of the adjustment ring 4, so that the above two rotation modes can be performed simultaneously without interfering with each other.

[0037] In another embodiment of the present invention, a first plate 23 is fixed to the inner wall of the drum 2 . The length direction of the first plate 23 is parallel to the axial direction of the drum 2 , and the width direction of the first plate 23 is arranged along the radial direction of the drum 2 .

[0038] Specifically, in the above embodiment, the inner wall of the drum 2 is an arc surface. When the drum 2 rotates around its own central axis, the seeds adhere to the inner wall of the drum 2 under the action of centrifugal force. When the seeds rotate with the drum 2 to a certain height in the mixing chamber 21, when their own gravity is greater than the component of the centrifugal force, the seeds will slide down along the inner wall of the drum 2, especially in the early stage of mixing when the biological bacteria agent is not adhered to the surface of the seeds. In order to achieve a better mixing effect, the drum 2 needs to rotate at a faster speed, which will cause serious damage to the seed surface. In this embodiment, the inner wall of the drum 2 is fixed with a first plate 23, such as Figures 4 to 6 As shown, the first plate 23 is rectangular, and the length direction of the first plate 23 is parallel to the axial direction of the drum 2, while the width direction of the first plate 23 is arranged along the radial direction of the drum 2. In this way, when the drum 2 rotates slowly, the first plate 23 can block part of the seeds, causing them to rotate with the drum 2 to a certain height and then fall, thereby improving the mixing effect while not causing significant damage to the seed surface.

[0039] Furthermore, the rotating drum 2 includes a fixed disk 24 and a cylinder 25, the cylinder 25 is rotatably connected to the fixed disk 24, a second bracket 12 is fixed to the support 1, the side wall of the fixed disk 24 is fixed to the limiting rod 241 along its own axial direction, the limiting rod 241 is symmetrically arranged on both sides of the fixed disk 24, an arc groove 121 is provided on the second bracket 12 to cooperate with the limiting rod 241, a second plate 242 is obliquely installed on the fixed disk 24, and the second plate 242 is arranged along the axial direction of the cylinder 25.

[0040] Specifically, in order to further improve the mixing effect of the seeds and the biological agent, in this embodiment, the rotating drum 2 includes a fixed disk 24 and a cylinder 25. The fixed disk 24 is rotatably mounted on the end of the cylinder 25 away from the feed port 22. A second plate 242 is mounted on the surface of the fixed disk 24 corresponding to the cylinder 25. The second plate 242 is tilted and arranged along the axial direction of the cylinder 25. Figures 4 to 6 As shown;

[0041] In order to keep the second plate 242 stationary when the cylinder 25 rotates, Figures 2 to 4 As shown, the side wall of the fixed plate 24 is fixedly connected to the limiting rod 241 along its own axial direction, and the upper surface of the support 1 is fixedly connected to the position of the fixed plate 24. The second bracket 12 is provided with an arc groove 121. Preferably, the limiting rod 241 and the arc groove 121 are provided in two groups, and the limiting rod 241 is symmetrically arranged on the fixed plate 24 at Figure 3The upper and lower sides of the view, the arc groove 121 and the limit rod 241 are arranged in a one-to-one correspondence, and the end of the limit rod 241 extends into the corresponding arc groove 121, and the center of the arc groove 121 is on the central axis of the rotating shaft 31. In this way, the limit rod 241 is used to limit the fixed disk 24. When the rotating drum 2 is driven to rotate about its own axis, the fixed disk 24 and the second plate 242 can remain stationary, and when the rotating drum 2 is driven to rotate about the central axis of the rotating shaft 31, the limit rod 241 can slide along the arc groove 121 and keep limiting the fixed disk 24.

[0042] In this embodiment, by installing the second plate 242 on the fixed disk 24, when the drum 2 drives the first plate 23 to rotate, the seeds falling from the first plate 23 can fall onto the second plate 242 and roll along the second plate 242. This arrangement can prevent the seeds from clumping due to the biological fungicide, and helps to evenly mix the seeds and the biological fungicide. In addition, the arrangement of the second plate 242 allows the seeds to fall in two strokes. The first stroke is when the seeds fall from the first plate 23 to the second plate 242 and slide along the surface of the second plate 242, and the second stroke is when the seeds fall from the second plate 242 to the inner wall of the drum 2. This reduces the impact force when the seeds fall and reduces the damage to the seed surface caused by the impact.

[0043] Preferably, the lower side of the second plate 242 corresponds to the bottom of the cylinder 25, and the upper side of the second plate 242 corresponds to the inner wall of one side of the cylinder 25, as shown in FIG. Figure 5 and Figure 6 As shown, the lower side of the second plate 242 is directly below the central axis of the cylinder 25, while the upper side of the second plate 242 is approximately in the same horizontal plane as the central axis of the cylinder 25. This arrangement ensures that the seeds on the first plate 23 can fall onto the second plate 242 to the greatest extent possible, while also increasing the inclination of the second plate 242 to prevent a large amount of seeds from adhering to the surface of the second plate 242 due to the viscosity of the biological inoculant, thereby affecting the mixing effect of the seeds and the biological inoculant.

[0044] In another embodiment of the present invention, the second plate 242 is rotatably mounted on the fixed disk 24 , and a torsion spring 243 is provided at the rotation axis of the second plate 242 . The first plate 23 pushes the second plate 242 to rotate as the drum 2 rotates.

[0045] Specifically, since the biological inoculant has a high viscosity, in the above embodiment, the second plate 242 is mounted on the fixed disk 24. As a result, when the seeds mixed with the biological inoculant are unloaded, some of the seeds will adhere to the second plate 242 and be difficult to remove, resulting in waste. In addition, during the mixing process of the seeds and the biological inoculant, some of the seeds will always adhere to the surface of the second plate 242. In this embodiment, the second plate 242 is rotatably mounted on the fixed disk 24, and a torsion spring 243 is provided at the rotation axis of the second plate 242. Figures 4 to 6 As shown, the first plate 23 can contact the second plate 242 near the upper side during the rotation of the drum 2 and push the second plate 242 to rotate. On the one hand, it can further increase the inclination of the second plate 242, making it easier for the seeds to slide from the lower side of the second plate 242 to the inner wall of the drum 2. On the other hand, after the first plate 23 passes over the second plate 242, the second plate 242 can return to its initial state under the action of the torsion force of the torsion spring 243. Figure 5 In the state shown, during this process, the vibration generated at the moment when the second plate 242 returns to its initial state can cause the seeds adhered to the surface of the second plate 242 to separate from the second plate 242.

[0046] Preferably, the first plate 23 is made of rubber so that the first plate 23 and the second plate 242 are in flexible contact, preventing the first plate 23 from being damaged. At the same time, it can also prevent the seeds from being squeezed by the first plate 23 and the second plate 242 and causing excessive damage to the skin.

[0047] Optionally, a mounting base 32 is fixedly connected to the upper portion of the sleeve 3, and the driving member includes a driving motor 33 fixedly connected to the mounting base 32. The driving motor 33 is also the motor in the above embodiment. The outer wall of the cylinder 25 is fixedly connected to a ring gear 251, and the output shaft of the driving motor 33 is fixedly connected to a gear 331. The gear 331 and the ring gear 251 are engaged with each other. In this way, when the drum 2 is in a horizontal state and when the drum 2 is in a state where the material port 22 is tilted downward, the driving motor 33 can drive the drum 2 to rotate. The driving motor 33 can be used to drive the drum 2 to rotate around its own central axis to assist in unloading.

[0048] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
