Abstract
Description
Technical Field
[0001] This application relates to the field of micro-tuber screening technology, and more specifically, to a grading and screening device for micro-tuber production. Background Technology
[0002] With the rapid development of my country's economy, agricultural production is facing increasing challenges and opportunities. As one of my country's main food crops, the propagation and introduction of potato varieties has broad market potential and enormous economic value. Microtubule potatoes are a new propagation technology that enables the propagation and introduction of potato varieties in a relatively short time, playing a significant role in promoting agricultural development and improving economic efficiency in my country.
[0003] In related technologies, potato mini-tubers need to be graded and collected according to their quality and size during harvest. Generally, the mini-tubers planted in seed trays are poured into a vibrating grading and screening machine for grading and screening.
[0004] However, in the actual grading and screening process, vermiculite and other substrates are used as the cultivation substrate for mini-tubers in the seed trays, and vermiculite has a strong water retention and moisture-locking function. As a result, a certain amount of vermiculite adheres to the surface of the potato mini-tubers, which in turn affects the grading and screening process. Utility Model Content
[0005] In view of this, the present application provides a grading and screening device for micro-potato production to solve the problem that grading vibration screening in the related art cannot remove vermiculite adhering to the surface of micro-potatoes.
[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:
[0007] A grading and screening device for micro-potato production includes:
[0008] frame;
[0009] A screening box is mounted on the frame via a vibration damping spring, and a vibration motor is fixedly mounted at the bottom of the screening box.
[0010] A primary sieve plate is disposed inside the screening box and is used for primary screening of micro-tubers;
[0011] A secondary sieve plate is disposed inside the screening box and is located below the primary sieve plate. The secondary sieve plate and the primary sieve plate form a stepped structure. The secondary sieve plate is used to screen the micro-tubers again.
[0012] A door-shaped support is arranged in the screening box, the door-shaped support is located between the first sieve plate and the second sieve plate, and the bottom end of the transverse section of the door-shaped support is provided with downwardly extending soft bristles extending along the length direction of the transverse section of the door-shaped support.
[0013] In some possible implementation manners, a notch is arranged at the vertical section of the door-shaped support, the notch is opened towards the width direction of the screening box, and the side surface of the screening box is provided with a collection box in communication with the notch.
[0014] In some possible implementation manners, a plurality of vertical strip holes are arranged on the wall surface of the screening box close to the collection box, and the vertical strip holes are in communication with the screening box.
[0015] In some possible implementation manners, a fan is further included.
[0016] The fan is arranged on the side surface of the screening box, and the fan is in communication with the notch to blow air towards the direction of the collection box.
[0017] In some possible implementation manners, the outer diameter of the sieve hole of the first sieve plate is greater than the outer diameter of the sieve hole of the second sieve plate.
[0018] In some possible implementation manners, the soft bristles are located above the second sieve plate, and the soft bristles are in contact with the upper surface of the first sieve plate.
[0019] The micro-potato production grading and screening device provided by the embodiment has at least the following beneficial effects:
[0020] In the micro-potato production grading and screening device, the micro-potatoes planted in the plug tray are poured onto the first sieve plate of the screening box, and the micro-potatoes move towards the discharge end under the action of vibration. At the same time, the vermiculite adhered to the surface of the micro-potatoes falls off under the action of vibration and falls into the interior of the screening box through the sieve hole. As the micro-potatoes continuously move, the micro-potatoes pass through the door-shaped support and enter the second sieve plate. The soft bristles arranged at the door-shaped support scrape the surface of the micro-potatoes, thereby removing the vermiculite adhered to the surface of the micro-potatoes. The above structure design can more thoroughly remove the vermiculite adhered to the surface of the micro-potatoes in the process of grading and screening. BRIEF DESCRIPTION OF DRAWINGS

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figs. 1-2 As shown in the figure, the grading and screening device for micro-potato production provided in this application embodiment includes a frame 100, a screening box 200, a primary sieve plate 500, a secondary sieve plate 600, and a U-shaped support 700. The screening box 200 is mounted on the frame 100, which can be a floor-mounted support used to support the screening box 200 on the ground. The screening box 200 is mounted on the frame 100 via vibration damping springs 300, and a vibration motor 400 is fixedly mounted at the bottom of the screening box 200. When the vibration motor 400 is started, the excitation force generated by the vibration motor 400 causes the screening box 200 to vibrate on the frame 100, thereby achieving the functions of vibration conveying and impurity removal.
[0028] The inside of the screening box 200 is respectively provided with a first screen plate 500 and a second screen plate 600, and the first screen plate 500 can perform primary screening on the potato microtubers. In actual use, the potato microtubers can be directly poured from the plug tray onto the first screen plate 500, and then under the action of vibration, the potato microtubers move towards the discharge end. In the moving process, the vermiculite adhered to the surface of the potato microtubers falls through the first screen plate 500 to the inside of the screening box 200, and the potato microtubers after vibration and impurity removal move to the discharge end for subsequent classification and screening operation.
[0029] Specifically, the second screen plate 600 is located below the first screen plate 500, and the second screen plate 600 and the first screen plate 500 form a stepped structure. When the potato microtubers pass through the stepped structure, they can fall downward and collide with the second screen plate 600, so that the surface-adhered impurities such as vermiculite can be removed. Preferably, the outer diameter of the screen hole of the second screen plate 600 is larger than that of the first screen plate 500.
[0030] In the embodiment, the screening box 200 is also provided with a door-shaped support 700 located between the first screen plate 500 and the second screen plate. The door-shaped support 700 includes a horizontal section 710 and vertical sections 720 located at both ends of the horizontal section 710 in the length direction, and the bottom end of the horizontal section 710 of the door-shaped support 700 is provided with soft bristles 800 extending downward. When the potato microtubers pass through the first screen plate 500 to the second screen plate 600, the soft bristles 800 on the door-shaped support 700 will scrape the surface of the potato to remove the vermiculite adhered to the surface.
[0031] In the classification and screening device for microtuber production provided in the embodiment, the potato microtubers planted in the plug tray are poured onto the first screen plate 500 of the screening box 200, and the potato microtubers move towards the discharge end under the action of vibration. At the same time, the vermiculite adhered to the surface of the potato microtubers falls off under the action of vibration and falls through the screen hole to the inside of the screening box 200. As the potato microtubers continuously move, they pass through the door-shaped support 700 and enter the second screen plate 600. The soft bristles 800 arranged at the door-shaped support 700 scrape the surface of the potato microtubers, thereby removing the vermiculite adhered to the surface. With the above structure, the vermiculite adhered to the surface of the potato microtubers can be more thoroughly removed during classification and screening.
[0032] In some embodiments, the vertical section 720 of the H-shaped bracket 700 is provided with a gap 721 at the bottom end of the vertical section 720, and the gap 721 is opened towards the width direction of the screening box 200. The side surface of the screening box 200 is further provided with a collection box 110 in communication with the gap 721. Preferably, the wall surface of the screening box 200 close to the collection box 110 is provided with a plurality of vertical strip holes 120 in communication with the collection box 110. In addition, the side surface of the screening box 200 can be further provided with a fan 900 in communication with the gap 721 and blowing towards the direction of the collection box 110.
[0033] In actual use, after the potato microtubers pass through the soft brush 800 of the H-shaped bracket 700, the vermiculite and other impurities scraped off will fall on the secondary sieve plate 600. The fan 900 can blow the part of the vermiculite and other impurities through the gap 721 and the vertical strip holes 120 into the collection box 110 for collection, so as to avoid the accumulation of the vermiculite and other impurities on the secondary sieve plate 600, thereby affecting the impurity removal process of the potato microtubers.
