Description

Technical Field

[0001] This utility model relates to the field of agricultural production equipment technology, specifically to a seed impurity removal mechanism for agricultural production. Background Technology

[0002] Agricultural seeds are the foundation of agricultural production and the key to the continuation and development of crop cultivation. They possess vitality and are special means of production; seeds such as corn, rice, and wheat have significant yield-increasing effects and are crucial to agricultural production. Agricultural seeds may contain undesirable impurities, such as fine sand, hard nodules, hard skin, shells, field weeds, wild grasses, and hybrid attachments. These impurities can affect the quality and reproductive capacity of seeds, and thus affect farmers' harvests. Therefore, it is usually necessary to use a sieve to screen the seeds and separate the impurities through the sieve holes according to the size of the seeds and the different types of impurities. However, some existing seed cleaning devices are limited in function and cannot perform multiple screening functions. For example, some devices may only be able to screen seeds of a specific size, but cannot grade seeds of different sizes, resulting in significant limitations in their use. Furthermore, existing cleaning mechanisms cannot remove impurities such as dust, straw, and ash adhering to the seeds during operation. These impurities may contain pathogens, fungi, or pests, which can negatively impact seed health and lead to a decline in seed quality. Therefore, a seed cleaning mechanism for agricultural production is proposed to address these issues. Utility Model Content

Detailed Implementation

[0013] 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.

[0014] Example 1: Please see Figure 1-5This embodiment of a seed impurity removal mechanism for agricultural production includes a mounting frame 1. The mounting frame 1 has a first connecting spring 11 fixedly connected to one side and a second connecting spring 12 fixedly connected to the other side. Both the first connecting spring 11 and the second connecting spring 12 are fixedly connected to a multi-stage screening assembly 2 for seed screening. A hopper 18 for placing seeds is provided at the top of the mounting frame 1. A baffle 181 for opening and closing is provided on the hopper 18. A discharge guide rail 182 for facilitating seed sliding is also provided at the bottom of the hopper 18. The discharge guide rail 182 is located within the multi-stage screening assembly. Above 2, a boss 183 is also provided on the discharge guide rail 182; the bottom of the mounting frame 1 is provided with a first mounting platform 13, a second mounting platform 14 and a third mounting platform 15 for support. A transmission motor 16 for transmission is provided on the first mounting platform 13. The transmission motor 16 is connected to the linkage component 3. The transmission motor 16 is connected to the fan housing 17 through the linkage component 3. A connecting air duct 171 is provided inside the fan housing 17. The connecting air duct 171 is connected to one side of the fan housing 17. The other end of the connecting air duct 171 is located above the discharge guide rail 182. A fan wheel 172 is also provided inside the fan housing 17.

[0015] As a preferred technical solution in this embodiment: In actual use, when it is necessary to remove impurities from the seeds, the operator first places the seeds to be removed into the hopper 18, and then controls the drive motor 16 to drive the linkage component 3 to make the multi-stage screening component 2 vibrate. During the vibration of the multi-stage screening component 2, the operator can control the baffle 181 to open, so that the seeds in the hopper 18 can fall into the baffle 181 through the hopper 18. When the seeds fall into the baffle 181 and come into contact with the discharge guide rail 182, the seeds can bounce up. When the seeds bounce up, some impurities attached to the seeds can be effectively shaken off. At this time, under the action of the drive motor 16, the linkage component 3 can drive the impeller 172 in the fan housing 17 to rotate. During the rotation of the impeller 172, negative pressure wind can be generated, and the impurities generated when the seeds bounce up at the baffle 181 can be collected and discharged through the connecting air pipe 171.

[0016] The technical effects of the above embodiments are as follows: by setting baffle 181 and discharge guide rail 182, the impurities attached to the seeds can be effectively removed during use; by setting connecting air duct 171 and impeller 172, the impurities can be effectively cleaned during use, thus effectively avoiding the situation where impurities are still mixed between seeds after seed screening, which would lead to a decline in seed quality.

[0017] Example 2: Please see Figure 1-5 To achieve a good transmission effect, the multi-stage screening assembly 2 in this embodiment includes a primary screening screen 21 for primary screening and a secondary screening screen 23 for secondary screening. The primary screening screen 21 has a primary discharge port 22 for material feeding, and the secondary screening screen 23 has a secondary discharge port 24 for material feeding. The bottom of the secondary discharge port 24 is also provided with a waste discharge port 25 for discharging impurities and a linkage plate 26 for transmission. The linkage assembly 3 includes a connecting shaft 31, which is rotatably connected to the second mounting platform 14. The connecting shaft 31 is provided with a first transmission belt 34 and a second transmission belt 38 for transmission. The first transmission belt 34 is rotatably connected to the transmission motor 16, and the connecting shaft 31 is provided with a transmission rod 35. The top of the third mounting platform 15 is rotatably connected to the linkage shaft 36, and the linkage shaft 36 is provided with a linkage wheel 37. The second transmission belt 38 is rotatably connected to the linkage wheel 37, and the other end of the linkage wheel 37 is rotatably connected to the impeller 172.

[0018] As a preferred technical solution in this embodiment: In actual use, when the operator controls the drive motor 16 to rotate, the drive motor 16 can drive the first drive belt 34 to rotate the double-groove pulley 33. During the rotation of the double-groove pulley 33, the drive table 32 can be driven to rotate. During the rotation of the drive table 32, the drive rod 35 can be driven to rotate. During the rotation of the drive rod 35, the linkage plate 26 can be driven to move. During the movement of the linkage plate 26, the secondary discharge port 24 and the primary discharge port 25 can be driven to move. The vibrating effect of the feed inlet 22 effectively enables the primary discharge outlet 22 to perform a first screening of the seeds. After the first screening, the seeds can be collected by the staff at the primary discharge outlet 22. Seeds that fail the first screening will fall onto the secondary screening screen 23 for a second screening. Seeds that pass the second screening can be discharged through the secondary discharge outlet 24. Finally, the impurities and shriveled seeds produced after the second screening through the secondary screening screen 23 can be discharged through the waste discharge outlet 25, thus completing the seed screening effect. Meanwhile, during the rotation of the connecting shaft 31, it can drive the double-groove pulley 33 to drive the second transmission belt 38, which in turn drives the linkage wheel 37 and the linkage shaft 36 to rotate. During the rotation of the linkage shaft 36, it can drive the impeller 172 to rotate, thereby generating negative pressure wind to clean the debris attached to the seeds.

[0019] It is worth noting that, in this embodiment, the output shaft of the drive motor 16 is provided with a pulley and is tensioned and connected to the double groove pulley 33 and the pulley by the first drive belt 34; in this embodiment, the connecting shaft 31 and the linkage shaft 36 are both provided with shaft heads, and the connecting shaft 31 and the linkage shaft 36 are connected to the second mounting platform 14 and the third mounting platform 15 through the shaft heads.

[0020] The technical effects of the above embodiments are as follows: by setting the linkage component 3, the seeds can be screened and cleaned by only one drive motor 16 during use, which effectively reduces the use cost of the device and saves energy. The secondary discharge port 24 facilitates the collection and processing of the screened impurities.

[0021] The working principle of the above embodiments is as follows: 1. In actual use, when it is necessary to remove impurities from seeds, the operator first places the seeds to be removed into the hopper 18. Then, the operator controls the drive motor 16 to drive the linkage component 3, causing the multi-stage screening component 2 to vibrate. During the vibration of the multi-stage screening component 2, the operator controls the baffle 181 to open, allowing the seeds in the hopper 18 to fall into the baffle 181. When the seeds fall into the baffle 181 and come into contact with the discharge guide rail 182, the seeds bounce up. When the seeds bounce up, some impurities attached to the seeds can be effectively shaken off. At this time, under the action of the drive motor 16, the linkage component 3 drives the impeller 172 in the blower housing 17 to rotate. During the rotation of the impeller 172, negative pressure air force can be generated, and the impurities generated when the seeds bounce up at the baffle 181 can be collected and discharged through the air duct 171.

[0022] II. In actual use, when the operator controls the drive motor 16 to rotate, the drive motor 16 drives the first drive belt 34, causing the double-groove pulley 33 to rotate. During the rotation of the double-groove pulley 33, the drive table 32 rotates. During the rotation of the drive table 32, the drive rod 35 rotates. During the rotation of the drive rod 35, the linkage plate 26 is displaced. During the displacement of the linkage plate 26, the secondary discharge port 24 and the primary discharge port 22 vibrate. This allows the primary discharge port 22 to effectively screen the seeds once. After the first screening, the seeds can be collected at the primary discharge port 22. Seeds that fail the first screening will fall onto the secondary screening screen 23 for a second screening. Seeds that pass the second screening can be discharged through the secondary discharge port 24. Finally, the impurities and shriveled seeds produced after the second screening through the secondary screening screen 23 can be discharged through the waste discharge port 25, thus completing the seed screening process.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
