Abstract
Description
Technical Field
[0001] This utility model relates to the field of grading and seed selection, specifically a grading and seed selection device for peanut cultivation. Background Technology
[0002] Before leaving the factory, shriveled peanut seeds need to be removed. Shriveled seeds have a smaller particle size than plump seeds, so a vibration screening method is generally used to screen and grade the seeds. The top of the vibration screening machine is the screening box, and the screening box is elastically connected to the support frame assembly below by springs.
[0003] In the existing technology, during the screening process, the seeds are directly discharged into the vibrating screen through the feed hopper, resulting in a large amount of seeds entering and being stacked. Therefore, in order to achieve effective screening, the length of the vibrating screen must be increased, resulting in a large area occupied by the device. Utility Model Content
[0004] The purpose of this invention is to provide a grading and seed selection device for peanut cultivation in order to solve the problems mentioned in the background art.

[0016] 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.
[0017] Please see Figures 1-3In this embodiment of the present invention, a grading and seed selection device for peanut planting includes a vibrating box 1. A vibrating motor is fixedly installed below the bottom plate of the vibrating box 1. An upper screening component 2 is installed above the inner cavity of the vibrating box 1, and a lower screening component 9 is installed below the inner cavity of the vibrating box 1. A feeding mechanism is installed at the high end of the vibrating box 1. The first feeding trough 4 of the feeding mechanism is directly opposite the upper part of the upper screening component 2, and the second feeding trough 5 of the feeding mechanism is connected to the upper part of the lower screening component 9. A through hole 8 is provided on the end plate of the vibrating box 1 to connect the second feeding trough 5 and the lower screening component 9.
[0018] In this embodiment: First, the vibration motor installed on the bottom plate of the vibration box 1 is started. The vibration motor runs and the vibration force generated by the running acts on the vibration box 1. At this time, the upper screening component 2 and the lower screening component 9 installed inside the vibration box 1 vibrate synchronously. Then, peanut seeds are added to the feed hopper 3. The seeds are then dispersed into the upper screening component 2 and the lower screening component 9 through the feeding mechanism for synchronous vibration screening. This avoids the problem of peanut seeds piling up due to overfeeding, which would cause inaccurate screening results.
[0019] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The feeding mechanism includes a feeding hopper 3 integrally formed above the first feeding trough 4 and the second feeding trough 5. A partition block 7 with a triangular cross-section is integrally formed at the top of the connection between the first feeding trough 4 and the second feeding trough 5. The feeding mechanism also includes a first guide block 10 and a second guide block 11 fixedly connected to both ends of the inner wall of the feeding hopper 3. There is a channel for seeds to pass through between the first guide block 10 and the second guide block 11. The channel is located directly above the partition block 7. The top of the first guide block 10 is formed with an inwardly inclined first inclined surface 12, and the top of the second guide block 11 is formed with an inwardly inclined second inclined surface 13.
[0020] In this embodiment: peanut seeds are added to the feed hopper 3. Under gravity, the seeds move downward along the feed hopper 3 and come into contact with the top of the first guide block 10 and the second guide block 11 as they move downward. At this time, the seeds enter the channel downward through the first inclined surface 12 and the second inclined surface 13 and move downward through the channel. Then they come into contact with the separator 7, at which point the seeds are separated into two parts. The seeds separated into two parts enter the upper screening component 2 and the lower screening component 9 through the first feed trough 4 and the second feed trough 5, respectively, for vibration screening.
[0021] Please refer to this carefully. Figure 1 and Figure 2Both the upper screening component 2 and the lower screening component 9 include two screens, one at the bottom and one at the top. There is a partition between the bottom screen of the upper screening component 2 and the top screen of the lower screening component 9. The screens, the partition, and the bottom end of the bottom plate of the vibrating box 1 are all connected to a discharge chute 6. The ports of the discharge chute 6 are staggered.
[0022] In this embodiment: after the seeds enter the upper screening component 2 and the lower screening component 9, the shriveled peanut seeds or impurities move downward through the uppermost screen, thereby separating the plump seeds from the shriveled seeds.
[0023] Since the mesh diameter of the upper screen of the upper screening component 2 and the lower screening component 9 is larger than the mesh diameter of the lower screen, the plump seeds are intercepted above the upper screen, thus achieving the separation effect.
[0024] The separated seeds are discharged outward through each discharge trough 6, and the receiving containers set at the output ports of each discharge trough 6 receive the selected seeds.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
