Description

Technical Field

[0001] This utility model relates to the technical field of substrate mixing equipment, and in particular to a seedling substrate screening and mixing device. Background Technology

[0002] In the agricultural seedling industry, the preparation of seedling substrate is a fundamental step to ensure the healthy growth of seedlings. An ideal seedling substrate needs to be scientifically mixed with a variety of materials with different properties, such as common peat moss, perlite, vermiculite, and various organic fertilizers. Their proper proportions and fine processing play a decisive role in the quality of the substrate.

[0003] For a long time, traditional seedling substrate mixing has relied heavily on manual labor. In this method, workers must transport different types of substrate materials one by one to the mixing area and then mix them using simple tools. The entire process has a very low degree of automation, consuming a large amount of manpower and time, and the mixing effect is difficult to guarantee. Moreover, manual mixing also faces serious dust pollution problems. When turning and stirring substrate materials, especially lighter materials like perlite, a large amount of dust is generated and permeates the work area. This dust not only poses a threat to the health of operators, and long-term inhalation can easily cause respiratory diseases, but also seriously pollutes the environment around the mixing station. Therefore, an integrated substrate mixing device with automated feeding, automated mixing, and high-efficiency material delivery functions has been designed to improve mixing efficiency. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that any use of terms such as "up," "down," "left," "right," "front," "back," "inner," and "outer" in this document is based solely on the accompanying drawings and is not intended to specifically limit the scope of this utility model.

[0024] like Figures 1-6As shown, a seedling substrate screening and mixing device includes a first fixed frame 1, a second fixed frame 3, a conveyor frame 2, and a mixing mechanism 5. The first fixed frame 1 has a rectangular frame structure, and the upper part of the first fixed frame 1 is provided with the conveyor frame 2 and the transport mechanism 4. The second fixed frame 3 is provided at one end of the first fixed frame 1, and the mixing mechanism 5 is provided at the upper part of the second fixed frame 3. The mixing mechanism 5 includes a mixing tank 501, a first stirring rod 502, a second stirring rod, a stirring blade 503, a sealing cover 504, and a spray nozzle. The spray pipe 505 and spray head 506, the first stirring rod 502 and the second stirring rod are arranged inside the mixing tank 501, and one end of the first stirring rod 502 and the second stirring rod are connected to the first drive group. The upper part of the first stirring rod 502 and the second stirring rod are provided with a plurality of stirring blades 503. The upper part of the sealing cover 504 is provided with a spray pipe 505, and the spray head 506 on the spray pipe 505 extends into the rectangular opening. One end of the spray pipe 505 is connected to the external water tank through the guide pump 507.

[0025] It should be noted that, in order to achieve automatic mixing and automatic transportation, a transportation mechanism 4 and a mixing mechanism 5 are respectively installed on the first fixed frame 1 and the second fixed support. The mixing mechanism 5 can cooperate with the leveling mechanism 7 to automatically guide materials and mix different materials. To achieve this function, a first stirring rod 502 and a second stirring rod are installed inside the mixing tank 501, and multiple stirring blades 503 are installed on the two stirring rods. This not only achieves material mixing, but also, due to the different shapes and angles of the stirring blades 503, the blades apply shearing, compressing, and stretching forces to the material when the shaft rotates. The speed and direction of the blades at different positions... The different directions cause relative movement between material particles, thereby breaking up material agglomerates and allowing materials to interpenetrate and mix. During the stirring process, the material near the center of the shaft moves slower, while the material far from the center of the shaft moves faster. This speed difference leads to friction and collision between materials, promoting mixing. Moreover, a first gear 508 and a second gear 509 are respectively provided at one end of the first stirring rod 502 and the second stirring rod. The first gear 508 and the second gear 509 are meshed and connected, and the second gear 509 is meshed and connected to the third gear 510 on the output shaft of the first drive motor 511. A protective cover 512 is provided on one side of the first gear 508 and the second gear 509.

[0026] It should be further explained that, driven by the stirring blades 503, the material forms a complex circulating flow pattern. The material is pushed from one end of the mixing tank to the other end, and then, under the influence of the tank wall and other factors, it flows back to the starting end in the opposite direction. This cycle repeats itself. During the circulation process, the material continuously exchanges and mixes with the material at different locations. At the same time, due to the interaction of the two stirring shafts, the material also forms a lateral flow and exchange between the two shafts, further enhancing the mixing effect, and the material is discharged from the outlet of the mixing tank 501.

[0027] It should be further explained that a sealing cover 504 is provided on the upper part of the mixing tank 501, and a rectangular opening is provided inside the sealing cover 504. A spray pipe 505 is provided on the upper part of the cover, and one end is connected to an external water source through a guide pump 507. Humidification is completed through the spray head 506 on the upper part of the spray pipe 505. This design can also suppress the dust generated during stirring and prevent dust from overflowing.

[0028] like Figures 1-6 As shown, a feeding mechanism 6 is provided at the inlet of the sealing cover 504. The feeding mechanism 6 includes a feeding bracket 601, a first conveyor belt 603, a second drive motor 602, and a feeding hopper 604. The first conveyor belt 603 is provided inside the feeding bracket 601, and the second drive motor 602 is provided on the side of the feeding bracket 601. The feeding hopper 604 is provided on the upper part of the feeding bracket 601.

[0029] It should be noted that, in order to achieve automatic feeding, one end of the feeding bracket 601 is connected to the inlet of the sealing cover 504, and feeding is carried out based on the first conveyor belt 603 inside the feeding bracket 601 to realize the automated transportation of materials, thereby achieving automatic feeding and lifting different materials.

[0030] like Figures 1-6 As shown, the transport mechanism 4 includes a rotating shaft 403, a second conveyor belt 402, a fourth gear 404, a fifth gear 405, and a third drive motor 406, all located at both ends of the conveyor frame 2. The second conveyor belt 402 is located on the upper part of the rotating shaft 403, and a fourth gear 404 is located at one end of the rotating shaft 403. The fourth gear 404 meshes with the fifth gear 405 on the output shaft of the third drive motor 406. The third drive motor 406 is located on a support platform 407 at one end of the first fixed frame 1. A first support frame 408 is located inside the conveyor frame 2, and two idler rollers 409 are located on the upper part of the first support frame 408. The two idler rollers 409 are arranged in a V-shape.

[0031] It should be noted that, in order to achieve automated transportation, rotating shafts 403 are set at both ends of the conveyor frame 2, and a second conveyor belt 402 is set on the upper part of the two rotating shafts 403. Based on the two idlers 409 on the internal first support frame 408, the second conveyor belt 402 can be folded to form a V-shaped structure, which facilitates the transportation of materials and prevents side spillage.

[0032] It should be further explained that, in order to achieve automated drive, a fifth gear 405 is provided on the output shaft of the third drive motor 406, and the fifth gear 405 meshes with the fourth gear 404 on the idler roller 409 to achieve drive. This gear structure can also change the rotation speed, making it convenient to control the lifting speed.

[0033] like Figures 1-6 As shown, it also includes a leveling mechanism 7, which includes a second support frame 701, a fixing plate 702 and a scraping plate 703. The fixing plate 702 is disposed inside the connecting groove of the second support frame 701, and the scraping plate 703 is disposed at the bottom of the fixing plate 702.

[0034] It should be noted that the material discharged from the bottom of the mixing tank 501 will accumulate after entering the upper part of the second conveyor belt 402. In order to achieve stable material transportation, we have set up a scraping mechanism 7 on the upper part of the first fixed frame 1. The scraping plate 703 can scrape the accumulated material to make it easier for the material to be lifted smoothly.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
