Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a seed dressing device for controlling wheat aphids. Background Technology

[0002] Wheat aphids are one of the major pests affecting wheat yield, and seed treatment is a crucial step in pest and disease control before sowing. This technique involves evenly coating wheat seeds with pesticides to protect them and control pests during the seedling stage.

[0003] Currently, equipment used for seed treatment typically includes a mixing chamber to hold the seeds and a stirring mechanism located inside the chamber. During the treatment process, the pesticide is sprayed onto the seeds, while the stirring mechanism simultaneously agitates and mixes the seeds and pesticide.

[0004] However, existing seed coating devices still have shortcomings in practical applications. On the one hand, wheat seeds to be coated often contain light impurities such as wheat bran and dust. During seed coating, these impurities not only absorb and consume valuable pesticides but also hinder effective contact between the pesticides and the seed surface, resulting in incomplete coating. On the other hand, traditional mixing mechanisms (such as a single rotating impeller) are often limited by their structural form and gravity, making it difficult to effectively agitate seeds piled at the bottom of the mixing tank, easily creating dead zones at the bottom of the tank.

[0005] The combined problems of impurities and uneven mixing at the bottom resulted in some seeds not being evenly coated with the pesticide, leading to poor overall seed treatment quality and directly affecting the subsequent aphid control effect.

[0006] Therefore, this utility model proposes a seed dressing device for controlling wheat aphids to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the problems in existing wheat aphid control seed dressing devices, such as impurities in the seeds affecting the adhesion of the pesticide and the formation of dead zones at the bottom of the mixing box leading to uneven seed dressing, this utility model aims to provide a wheat aphid control seed dressing device with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a seed dressing device for controlling wheat aphids, including: a support frame, a mixing box fixed on the support frame, and at least two parallel rotating rollers rotatably connected inside the mixing box, with multiple stirring plates fixedly connected to the outer wall of the rotating rollers; it also includes a cleaning mechanism and a stirring mechanism disposed above the mixing box.

[0009] The discharge end of the cleaning mechanism is connected to the inlet end of the mixing box.

[0010] Furthermore, the stirring mechanism includes a side chamber disposed on one side of the mixing tank, and a drive assembly disposed within the side chamber. The drive assembly includes a motor, a rotating shaft driven by the motor, and a belt assembly.

The stirring mechanism also includes a pushing assembly fixed to the outer wall of the mixing tank. The output end of the pushing assembly is fixedly connected to a mixing plate disposed at the bottom of the mixing tank via a connecting plate, and the pushing assembly is used to drive the mixing plate to reciprocate at the bottom of the mixing tank.

[0011] Preferably, the cleaning mechanism includes a housing, a feed hopper disposed on the top of the housing, a plurality of diversion columns disposed inside the housing along the seed falling path, a vacuum fan installed on one side of the housing, a baffle plate disposed inside the housing and located on the suction path of the vacuum fan, and a collection box detachably installed on the bottom of the housing.

[0012] Preferably, the plurality of drainage columns are arranged in an alternating pattern.

[0013] Preferably, the barrier plate has a mesh or grid structure and is disposed between the vacuum fan and the diversion column.

[0014] Preferably, the pushing component is a cylinder, the telescopic shaft of the cylinder serves as the output end of the pushing component, and the end of the telescopic shaft passes through the wall of the mixing tank and is fixedly connected to the connecting plate.

[0015] Preferably, the wheat aphid control agent seed dressing device further includes a storage tank, a transport pipe, and a spray pipe; the storage tank is fixed on the support frame, one end of the transport pipe is connected to the outlet of the storage tank, and the other end is connected to the spray pipe installed inside the mixing tank.

[0028] Example:

[0029] Reference Figures 1 to 4 This utility model provides a seed dressing device for controlling wheat aphids, which aims to solve the problems in the prior art where seed impurities affect the adhesion of the pesticide and the mixing dead zone at the bottom of the mixing box easily forms, resulting in uneven seed dressing.

[0030] like Figure 1 As shown, the wheat aphid control seed treatment device includes a support frame 1 and a mixing box 2 fixedly connected to the support frame 1. The support frame 1 provides the installation and support foundation for the entire device. The mixing box 2 is used to hold seeds and pesticides for mixing. The cleaning mechanism 4 is located above the mixing box 2. The discharge end of the cleaning mechanism 4 is connected to the inlet end of the mixing box 2 and is used to pre-clean the seeds before they enter the mixing box 2.

[0031] Reference Figure 1 and Figure 4 The stirring mechanism 3 is located inside and on one side of the mixing box 2. The stirring mechanism 3 includes a structure for upper-level rotary stirring and a structure for lower-level reciprocating stirring. These two structures work together to achieve uniform mixing of seeds without dead angles. The upper-level rotary stirring structure includes a side box 31, a drive assembly 32, at least two rotating rollers 33, and multiple stirring plates 34. The lower-level reciprocating stirring structure includes a push assembly 35, a connecting plate 36, and a mixing plate 37.

[0032] Specifically, a drive assembly 32 is provided in the side box 31 located on one side of the mixing box 2. The drive assembly 32 includes a motor 321, a rotating shaft 322, and a belt assembly 323. The motor 321 is fixed inside the side box 31. The output shaft of the motor 321 drives the rotating shaft 322 to rotate. The rotating shaft 322 passes through the side box 31 and extends into the mixing box 2. The rotating shaft 322 is fixedly connected to one of the rotating rollers 33. Two parallel rotating rollers 33 are rotatably connected inside the mixing box 2. The belt assembly 323 is connected between the two rotating rollers 33, so that the two rotating rollers 33 can rotate synchronously through the drive of the motor 321. Multiple stirring plates 34 are fixedly connected to the outer wall of each rotating roller 33. The stirring plates 34 agitate and stir the material in the upper part of the mixing box 2 as the rotating roller 33 rotates.

[0033] The pushing component 35 is fixed to the outer wall of the mixing box 2. The output end of the pushing component 35 passes through the box wall of the mixing box 2 and is fixedly connected to the mixing plate 37 set at the bottom of the mixing box 2 through the connecting plate 36. The pushing component 35 drives the mixing plate 37 to move back and forth at the bottom of the mixing box 2 in a direction parallel to the axis of the rotating roller 33, thereby turning the seeds at the bottom up. Together with the upper rotating stirring plate 34, it completes the thorough mixing of all the seeds in the box.

[0034] Reference Figure 1 and Figure 2The cleaning mechanism 4 includes a housing 43 and a feed hopper 41 disposed on the top of the housing 43. Seeds enter the interior of the housing 43 through the feed hopper 41. The discharge end of the housing 43 is connected to the feed end of the mixing box 2. The cleaned seeds can fall directly into the mixing box 2. Multiple staggered guide columns 42 are arranged inside the housing 43 along the seed falling path. During the falling process, the seeds collide with the guide columns 42 and are divided and dispersed.

[0035] Meanwhile, a vacuum fan 44 is installed on one side of the outer casing 43. When the vacuum fan 44 is working, it generates negative pressure airflow inside the outer casing 43. In the suction path of the vacuum fan 44, that is, between the vacuum fan 44 and the guide column 42, a mesh or grid-like baffle plate 45 is provided. The airflow passes through the baffle plate 45 and is discharged by the vacuum fan 44. Lighter impurities such as dust and wheat chaff that fall with the seeds are carried away from the seeds by the airflow and blocked by the baffle plate 45. A collection box 46 is detachably installed at the bottom of the outer casing 43. The debris blocked by the baffle plate 45 falls into the collection box 46 under the action of gravity, which is convenient for unified cleaning.

[0036] As a preferred embodiment, please refer to Figure 1 and Figure 4 The pushing component 35 is specifically a cylinder 351. The cylinder body of the cylinder 351 is fixed on the outer side wall of the mixing box 2. The telescopic shaft 352 of the cylinder 351 serves as the output end of the pushing component 35. The end of the telescopic shaft 352 passes through the box wall of the mixing box 2 and is fixedly connected to the connecting plate 36. The other end of the connecting plate 36 is fixedly connected to the mixing plate 37.

[0037] As another preferred embodiment, please refer to Figure 1 and Figure 3 The device also includes a structure for conveying and spraying the pesticide, which includes a storage tank 38, a transport pipe 39, and a spray pipe 310. The storage tank 38 is fixed on the support frame 1 and is used to store liquid pesticide for controlling aphids. One end of the transport pipe 39 is connected to the outlet of the storage tank 38, and the other end is connected to the spray pipe 310 located inside the mixing box 2. The spray pipe 310 is located above the two rotating rollers 33 and extends along the axial direction of the rotating rollers 33. Multiple downward-facing spray holes are opened on its pipe wall to evenly spray the pesticide onto the seeds below.

[0038] As another preferred embodiment, please refer to Figure 4 The mixing plate 37 is a flat plate structure, and its width is adapted to the width of the inner bottom wall of the mixing box 2, which can push the seeds at the bottom over a large area; the reciprocating motion direction of the mixing plate 37 is parallel to the axis of the rotating roller 33.

[0039] As another preferred embodiment, please refer to Figure 2Multiple drainage columns 42 are arranged in a staggered manner in the vertical direction. When the seeds fall, they will continuously collide with the drainage columns 42 at different positions, thus being fully divided and dispersed, extending their time in the cleaning mechanism 4.

[0040] As another preferred embodiment, please refer to Figure 2 The barrier plate 45 has a mesh or grid structure, which can ensure smooth airflow and effectively intercept various debris drawn in by the vacuum fan 44.

[0041] The working principle is as follows:

[0042] First, the seeds are cleaned by pouring the wheat seeds to be treated into the cleaning mechanism 4 through the feed hopper 41. The seeds fall downwards under their own weight, and as they pass through multiple staggered guide columns 42, they are continuously broken down and dispersed, slowing their descent and prolonging their airtime. During this process, the vacuum fan 44 is activated, creating a negative pressure airflow within the outer casing 43. Lightweight debris such as dust and wheat chaff accompanying the falling seeds are absorbed by the airflow and intercepted by the mesh or grid-like baffles 45, subsequently falling into the collection box 46 at the bottom. The cleaned, pure seeds continue to fall and enter the mixing chamber 2 through the discharge end of the cleaning mechanism 4.

[0043] Next, the seed treatment process begins. After the cleaned seeds enter the mixing chamber 2, the agent in the storage tank 38 is transported to the spray pipe 310 via the transport pipe 39, and then evenly sprayed onto the seeds through the spray holes on the spray pipe 310. Simultaneously, the stirring mechanism 3 is activated. The motor 321 located in the side chamber 31 drives the rotating shaft 322 to rotate, which, through the belt assembly 323, drives two rotating rollers 33 to rotate synchronously. Multiple stirring plates 34 fixed to the rotating rollers 33 rotate accordingly, thoroughly tumbling and mixing the seeds in the upper part of the mixing chamber 2.

[0044] Simultaneously, the cylinder 351 in component 35 is activated, and its telescopic shaft 352 drives the mixing plate 37 at the bottom of the mixing box 2 to move back and forth through the connecting plate 36. This reciprocating motion effectively turns over the seeds piled at the bottom, eliminates dead corners in the mixing, and ensures that every seed in the box can fully contact the rotating mixing plate 34 and the sprayed agent, ultimately achieving uniform seed mixing.
