Description

Technical Field

[0001] This utility model relates to the technical field of seed coating drying equipment, and in particular to a novel seed coating drying device. Background Technology

[0002] After the seeds are coated, a moist film will adhere to their surface.

[0003] Currently, the most common method for drying coated seeds is large-scale sun-drying. This method requires a large space, is easily affected by weather, and has low drying efficiency. Large roller or conveyor belt drying equipment is also used, which significantly improves efficiency, but the equipment is complex and bulky, making it inconvenient for field operations.

[0004] Importantly, existing drying equipment primarily relies on heating to improve efficiency, as illustrated by Chinese utility model patents with publication numbers CN220897138U, CN219087757U, and CN218380362U. However, temperature significantly impacts seed survival, and different crops have varying drying temperature requirements. For example, wheat, corn, soybeans, and peanut seeds require precise temperature control during drying. Excessive temperature can cause premature ripening or even over-cooking, while insufficient temperature will hinder effective drying.

[0005] Therefore, heat drying can easily lead to unstable quality. Furthermore, heat drying requires thorough stirring of the seeds; otherwise, uneven drying can occur, affecting the survival rate after sowing. Utility Model Content

[0006] This invention provides a novel seed coating and drying device to solve the problems mentioned in the background section. It does not employ a heating drying method, thus maximizing seed survival rate and drying quality, and is suitable for various crop seeds. Furthermore, it is small in size, low in cost, highly efficient, and easy to operate in the field.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A novel seed coating and drying device includes a drying chamber for containing materials, with a material inlet at a high position and a material outlet at a low position.

[0009] Also includes:

[0010] A material turning mechanism is placed inside the drying chamber and turns the material from bottom to top.

[0011] In addition, there is an air inlet duct that connects to the air supply component and dries the material in the drying chamber.

[0012] As a further improvement of this utility model, the material turning mechanism includes:

[0013] The material-turning component, driven by the drive component, turns the material at the bottom of the drying chamber upwards;

[0014] In addition, a channel pipe, which is adapted to be connected to the outer periphery of the turning component, with its bottom end close to the bottom of the drying chamber and its top end not higher than the top of the turning component.

[0015] As a further improvement of this utility model, the material turning component is a screw or an auger.

[0016] As a further improvement of this utility model, the top end of the channel tube is provided with a loose material skirt extending in the direction of its outer periphery.

[0017] As a further improvement of this utility model, the height of the end of the bulk material skirt away from the channel tube is lower than the height of the end of the bulk material skirt close to the channel tube, and the bulk material skirt is provided with a plurality of material dropping holes penetrating its thickness direction.

[0018] As a further improvement of this utility model, the material inlet is provided with a baffle tube extending toward the material turning mechanism, and the baffle tube and the material turning mechanism are spaced and corresponding.

[0019] As a further improvement of this utility model, the blowing direction of the air inlet pipe is tangent to the inner wall of the drying chamber.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the following is a summary description. Figure 1 To be continued Figure 7 The present invention will be further described in detail with reference to embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention. Example 1

[0038] The purpose of this embodiment is to provide a seed coating and drying device with a specific structure.

[0039] This embodiment discloses a novel seed coating and drying device, including a drying chamber 100 for containing materials 4 (such as seeds of common crops like wheat, corn, soybeans, and peanuts). The drying chamber 100 has an inverted conical structure, with a tapered bottom for easy material collection. Multiple viewing windows at different locations can also be provided on the outer surface of the drying chamber 100 to allow workers to monitor the internal operations. The drying chamber 100 is fixed to a movable frame 5, and its overall vertical arrangement saves space and facilitates movement.

[0040] A material inlet 101 is located at a high position in the drying chamber 100. For ease of operation, the material inlet 101 is preferably positioned at the center of the top of the drying chamber 100, allowing materials to fall into it from top to bottom. Alternatively, the material inlet 101 can be located on one side of the top of the drying chamber 100. A material outlet 103 is located at a low position in the drying chamber 100. In practice, multiple material outlets 103 at different heights and positions can be installed to facilitate simultaneous material collection by multiple workers, thereby improving efficiency.

[0041] In this embodiment, a material-turning mechanism is also included, which is placed inside the drying chamber 100 and turns the material 4 from bottom to top. Specifically, it is arranged at the vertical central axis of the drying chamber 100, allowing the material to turn upwards from the bottom within the drying chamber 100. When the material reaches the top of the turning mechanism, it falls naturally due to the lack of obstruction, forming a radially spreading scattering pattern as it falls, thus creating a reciprocating circulation path (see details for reference). Figure 5 (The direction indicated by the solid arrow).

[0042] And the air inlet pipe 301, which is connected to the air supply component 300 and air-dries the material 4 in the drying chamber 100. It uses the outside wind to dry the material, which is especially effective for drying materials in a scattered state.

[0043] The material-turning mechanism described in this embodiment includes a material-turning component 200, which is actually a screw feeder or a feeding auger. Driven by a drive component 201 (such as a drive motor), it turns the material 4 at the bottom of the drying chamber 100 upwards. The drive component 201 can be arranged at the bottom of the drying chamber 100, and the drive shaft extends through the drying chamber 100 to drive the material-turning component 200.

[0044] Furthermore, the channel pipe 202 has two through-holes in its axial direction. The channel pipe 202 can be fitted to the outer periphery of the turning component 200 to form a vertical path channel, through which the material 4 can be effectively conveyed and turned upward by the turning component 200. The bottom end of the channel pipe 202 is close to the bottom of the drying chamber 100, forming a gap 2021 through which the material can enter. Alternatively, the bottom end of the channel pipe 202 can be connected to the drying chamber 100 by a connecting rod for support. The top end of the channel pipe 202 is not higher than the top end of the turning component 200, so that the material can overflow smoothly. The overflowing material will radiate outwards and naturally fall, widening the gaps between the materials 4, which is conducive to external wind drying.

[0045] Because material 4 is circulated and turned over repeatedly in the drying chamber 100, after a certain drying cycle, the material can achieve the required drying effect and then be discharged through the material discharge port.

[0046] Throughout the operation, material 4 is conveyed upwards to a high position and then thrown out under centrifugal force, scattering in a radial pattern (or an "umbrella" pattern). The speed of the drive component affects the magnitude of the centrifugal force on the material. Of course, the rotation speed cannot be too high, otherwise excessive centrifugal force will cause the seeds to collide violently and be lost.

[0047] This invention improves upon the traditional heating and drying method by using air drying, minimizing the impact of temperature on seeds, ensuring survival rates, and making it suitable for a wider variety of crop seeds. Furthermore, the overall structure is significantly simplified, resulting in a smaller size that is more suitable for field operations. Example 2

[0048] The purpose of this embodiment is to provide a seed coating and drying device with another structure, and the similarities with Embodiment 1 will not be repeated.

[0049] In this embodiment, the top end of the channel tube 202 is provided with a material-spreading skirt 203 extending outwards. The reason for providing the material-spreading skirt 203 is to maximize the spreading area of ​​the material 4 when the rotational speed of the driving component 201 is low. That is, supported by the material-spreading skirt 203, the material 4 will slowly spread out in a flat state, rather than spreading out in a small area. This increases the gap between the material 4, which is more conducive to air drying.

[0050] In addition, the height of the end of the bulk material skirt 203 away from the channel pipe 202 is lower than the height of the end of the bulk material skirt 203 near the channel pipe 202, which facilitates the rolling of the material 4. The bulk material skirt 203 is provided with several material drop holes that run through its thickness direction, so the material 4 will fall in a "rain"-like manner, which is more conducive to air drying.

[0051] In addition, in the above embodiments, in order to achieve a better airflow turbulence effect, the material inlet 101 is provided with a turbulence pipe 102 extending toward the material turning mechanism, and the turbulence pipe 102 and the material turning mechanism are spaced and correspond to each other.

[0052] By setting the downward-extending baffle 102, the air can be prevented from being discharged too quickly, and a more obvious spiral wind effect can be achieved. The air convects in a spiral manner inside the drying chamber 100, which prolongs the air residence time, and the material 4 has a longer contact time with the air and a wider contact area, thereby improving the drying effect of the material.

[0053] The reason for the interval between the air inlet pipe and the material turning mechanism is to form a gap 2022 between them. This gap 2022 facilitates the exhaust of air, which is deflected upwards at this point. In actual use, the port of the air inlet pipe 301 is located on one side of the turbulence pipe 102, at a tangential angle to the inner wall of the drying chamber 100. This allows the air to more easily achieve a spiral convection flow path, rather than being directly and rapidly exhausted from the material inlet 101. Of course, the air inlet pipe 301 can also be arranged at a near-tangential angle, as long as the spiral convection effect of the air can be achieved.

[0054] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
