Description

Technical Field

[0001] This utility model relates to the field of wheat seed pretreatment technology, and in particular to a wheat seed drug soaking device. Background Technology

[0002] In modern agricultural production, seed treatment before sowing is crucial for improving crop yield and quality. Soaking seeds in chemicals effectively disinfects, controls pests and diseases, and promotes seed germination. For wheat, a major food crop, seed soaking is a key step in ensuring stable and high yields.

[0003] To ensure the effectiveness of the soaking process and conserve pesticides, wheat seeds typically need to be screened before soaking to remove large impurities, damaged seeds, and shriveled or small-sized seeds, allowing only plump, high-quality seeds to be treated. Therefore, integrated devices combining screening and soaking functions have emerged. These devices usually include a vibrating screening mechanism that separates seeds by moving the screen.

[0004] However, many existing screening mechanisms have complex drive structures, and the vibrations generated during operation are often unstable, resulting in irregular swaying rather than smooth reciprocating motion. This unstable motion can lead to uneven seed distribution on the screen, affecting the accuracy and efficiency of screening. Furthermore, severe or irregular vibrations may cause collision damage to the seeds themselves, affecting their germination rate, which contradicts the original purpose of seed treatment.

[0005] Therefore, this utility model proposes a wheat seed drug soaking device to overcome the shortcomings of the prior art. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 5 This utility model provides a wheat seed drug soaking device, which aims to solve the problems of complex screening structure, inconvenient screen replacement leading to low screening efficiency, and easy seed damage caused by mechanical stirring during the soaking process in the prior art.

[0031] like Figure 1 As shown, the wheat seed soaking device includes a support plate 1 and a screening mechanism 3 fixedly connected to the top of the support plate 1. Several support feet 2 are fixedly connected to the bottom of the support plate 1. The support plate 1 and the support feet 2 together form the mounting base of the device. The screening mechanism 3 is used to grade and screen wheat seeds.

[0032] like Figure 2 and Figure 3As shown, the screening mechanism 3 includes a screening chamber 31, inside which a primary sieve plate 36 and a secondary sieve plate 37 are detachably installed. A pair of parallel guide rails 34 are fixedly mounted on the inner wall of the screening chamber 31. The screening mechanism 3 also includes a drive plate 3111. T-blocks 35 are fixedly connected to both sides of the drive plate 3111, and each T-block 35 is slidably connected to the corresponding guide rail 34. The primary sieve plate 36 and the secondary sieve plate 37 are bolted to the drive plate 3111, thereby enabling the drive plate to... The primary sieve plate 36 and the secondary sieve plate 37 can be driven to slide back and forth stably along the length of the guide rail 34. The screening mechanism 3 further includes a drive assembly 311, which includes a motor 3116 fixed to the outside of the screening mechanism 3. The output end of the motor 3116 is connected to the drive plate 3111. By starting the motor 3116, power can be output to drive the drive plate 3111 and drive the primary sieve plate 36 and the secondary sieve plate 37 to reciprocate along the length of the guide rail 34, thereby realizing the vibration screening of seeds.

[0033] To achieve stable drive more specifically, the core of the technical solution in this embodiment lies in the specific transmission structure inside the drive assembly 311. Furthermore, this transmission structure forms a specific connection relationship with the aforementioned motor 3116 and drive board 3111. Please refer to the following for details. Figure 2 The core driving structure will be described in detail below:

[0034] The drive assembly 311 also includes a drive shaft 3115, a turntable 3114, a moving shaft 3113, and a fixed plate 3112. The output end of the motor 3116 is fixedly connected to one end of the drive shaft 3115 by a key connection, and the other end of the drive shaft 3115 is fixedly connected to the center of the turntable 3114 to ensure that the turntable 3114 can rotate synchronously with the start of the motor 3116. One end of the moving shaft 3113 is eccentrically rotatably connected to the surface of the turntable 3114, and the other end of the moving shaft 3113 is rotatably connected to the fixed plate 3112. The fixed plate 3112 is finally fixedly connected to one side of the drive plate 3111. This crank-slider transmission mechanism composed of the turntable 3114 and the moving shaft 3113 can efficiently and smoothly convert the rotational motion output by the motor 3116 into the reciprocating linear motion of the drive plate 3111 along the guide rail 34, thereby ensuring the stability and continuity of the screening process.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0036] As a preferred embodiment, to achieve automatic soaking treatment of qualified seeds, please refer to... Figure 1 , Figure 4 and Figure 5The device also includes a soaking mechanism 4, which is located below the screening mechanism 3 to receive the screened seeds by gravity. The soaking mechanism 4 includes a soaking chamber 41, a storage tank 45, and a circulation pump 47. The bottom of the soaking chamber 41 is connected to the top of the storage tank 45 through an outlet pipe 44. The bottom of the storage tank 45 is connected to the inlet of the circulation pump 47 through a connecting pipe 46. The outlet of the circulation pump 47 is connected to the upper part of the soaking chamber 41 through an inlet pipe 48, thus forming a complete liquid circulation loop.

[0037] As a further optimization of the soaking mechanism 4, in order to facilitate observation and prevent seeds from entering the circulation pipeline, the side wall of the soaking chamber 41 is provided with an observation port 42 made of transparent material. The bottom of the interior of the soaking chamber 41 is covered with a filter plate 43, which has multiple holes with a diameter much smaller than the minimum diameter of wheat seeds.

[0038] As a preferred embodiment, for ease of replacing sieve plates of different specifications and collecting materials of different grades, please refer to... Figure 2 The screening mechanism 3 also includes a movable plate 32, which is used to load and unload the primary screen plate 36 and the secondary screen plate 37. Collection boxes 33 are fixedly connected to both sides of the movable plate 32. The collection boxes 33 are slidably disposed at the bottom of the screening chamber 31 to collect fine materials that pass through the secondary screen plate 37.

[0039] As a further refinement of the material collection path, a material inlet is provided on the front side of the screening chamber 31. The screening mechanism 3 also includes a collection box 39 and a receiving box 310. The collection box 39 and the receiving box 310 are used to receive the material sliding down from the primary and secondary sieve plates 37, respectively. A moving block 38 is inclinedly fixed on the bottom wall of the screening chamber 31. The inclined surface of the moving block 38 can guide the material screened out by the primary sieve plate 36 into the collection box 39 and guide the qualified seeds screened out by the secondary sieve plate 37 into the receiving box 310.

[0040] The working principle is as follows:

[0041] During screening, the staff first loads the primary sieve plate 36 and the secondary sieve plate 37 of the corresponding aperture size into the screening chamber 31 by pulling the movable plate 32, according to the wheat variety to be processed. These plates are then fixedly connected to the drive plate 3111. Next, the seeds to be screened are placed into the screening chamber 31, and the motor 3116 is started. The motor 3116 drives the turntable 3114 to rotate via the drive shaft 3115. The turntable 3114 then converts the rotational motion into the drive plate 3111 via the eccentrically positioned movable shaft 3113 and the fixed plate 3112. The reciprocating linear motion, due to the precise sliding cooperation between the T-shaped block 35 on the drive plate 3111 and the guide rail 34 on the inner wall of the screening chamber 31, causes the primary sieve plate 36 and the secondary sieve plate 37 to reciprocate stably and continuously. Large particles of impurities are intercepted by the primary sieve plate 36 and guided into the collection box 39 via the moving block 38. Qualified plump seeds pass through the primary sieve plate 36 and are intercepted by the secondary sieve plate 37, and are guided into the receiving box 310 via the moving block 38. Dried or small-diameter seeds pass through the secondary sieve plate 37 and fall into the collection box 33 below.

[0042] After qualified seeds enter the soaking chamber 41 of the soaking mechanism 4 through the receiving box 310, the circulation pump 47 is started. The liquid in the storage tank 45 is sucked into the circulation pump 47 through the connecting pipe 46, and then pumped into the upper part of the soaking chamber 41 through the inlet pipe 48. The liquid flows from top to bottom through the seed layer to achieve gentle soaking. After soaking, the liquid passes through the filter plate 43 at the bottom and flows back to the storage tank 45 through the outlet pipe 44, forming a continuous circulating soaking process. The presence of the filter plate 43 ensures that the seeds do not enter the circulation pump 47 and the pipeline system, avoiding mechanical damage to the seeds caused by traditional stirring methods. The staff can monitor the liquid level in the chamber in real time through the observation port 42.
