Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening, in particular to a screening device. Background Art
[0002] Seeds are the reproduction system of seed plants and play an important role in the continuation of species. Seeds are closely related to human life. In addition to grain, oil, and cotton, which are necessary in daily life, some medicines (such as almonds), seasonings (such as pepper), and beverages (such as coffee and cocoa) all come from seeds. Plants, trees, flowers and plants are also reproduced from seeds. Many seeds can be eaten and are delicious dishes on the table.
[0003] At present, most seed screening methods are to place the seeds in water. Seeds with lower density float and seeds with higher density sink to the bottom. Screening by this method will soak the seeds, which can easily affect the germination rate in the later stage. At the same time, traditional screening devices can only replace the screen as a whole to screen seeds of different diameters, which greatly affects the efficiency during work, and the cost of using the screen is higher. For this reason, we propose a screening device. Utility Model Content

[0026] Example:
[0027] See also Figure 1-3 The utility model provides a technical solution: a screening device, comprising a screening box 1, the screening box 1 is a hollow box-shaped body with an outlet arranged at the lower side, and an openable top cover is arranged on the top of the screening box 1; the screening box 1 is made of stainless steel, the top cover is stuck on the top of the screening box 1, and the top cover and the screening box 1 are connected by hinges;
[0028] The screening net 4 includes a screening panel 41 and an adjusting panel 42. The screening panel 41 has two upper and lower screening panels 41, and the upper and lower screening panels 41 are close to each other. The adjusting panel 42 is arranged in the middle of the two screening panels 41 and is slidably installed.
[0029] The four corners of the two screening panels 41 are provided with adjustment slots 43, and the adjustment slots 43 are provided with locking bolts 44. The locking bolts 44 are screwed downwardly to the upper screening panel 41, the adjustment panel 42 and the lower screening panel 41 in sequence, so as to screw and fix the screening panel 41 and the adjustment panel 42 to each other;
[0030] The screening panel 41 is provided with uniform screening holes, and the regulating panel 42 is provided with uniform leakage holes, but the adjacent leakage holes are provided with closed barrier plates;
[0031] The leakage holes and the screening holes correspond to each other and have the same hole diameter. When the adjustment panel 42 is misaligned, the blocking plate is blocked in the screening hole.
[0032] A feed hopper 2 is connected to the upper side of the left wall of the screening box 1 , and the feed hopper 2 penetrates the left wall of the screening box 1 and extends to the inside of the screening box 1 ; the feed hopper 2 is used to add seeds to be screened into the screening box 1 .
[0033] A screening net 4 is provided below the inner cavity of the screening box 1, and the outer wall of the screening net 4 is connected to the inner wall of the screening box 1. Here, the screening net 4 is hung on the inner wall of the screening box 1 by a hook, and when screening different seeds, different screening nets 4 can be replaced.
[0034] Preferably, the feed hopper 2 is arranged in an inclined shape with the left side higher and the right side lower, so as to facilitate the seeds to be poured into the screening box 1.
[0035] Preferably, a collecting hopper 5 is provided below the screening box 1, and the four lower corners of the screening box 1 are supported on the collecting hopper 5 by springs 6, and the collecting hopper 5 is arranged in a shape with an upper opening.
[0036] Preferably, a discharge port 7 with a cover is provided on the lower side of the collecting hopper 5 .
[0037] Preferably, support rods 8 are provided at four corners of the lower surface of the collecting bucket 5 .
[0038] Preferably, a vibration motor 3 is provided on the left side of the screening box 1 .
[0039] Pour the seeds from the feed hopper 2 into the screening box 1. The seeds fall downward under the action of gravity. Under the screening action of the screening net 4, the large-grained seeds stay on the upper side of the screening net 4, and the small-grained seeds fall from the sieve holes of the screening net 4 and are collected in the collecting bucket 5.
[0040] When the vibration motor 3 is working (the vibration motor 3 adopts the existing motor-driven eccentric block to achieve vibration), the screening box 1 swings on the spring 6, so that the seeds on the screening net 4 shake quickly to achieve screening and prevent small-particle seeds from accumulating on the upper side of the screening net 4;
[0041] When using this solution, the diameter of the screening hole can be adjusted. Specifically, the adjustment panel 42 is pushed left and right so that the leakage hole and the screening hole diameter are offset from each other, and the diameter of the screening hole is limited by the barrier plate. The adjustment range is the length of the adjustment groove 43. After adjustment, the locking bolts 44 are used to fix the upper and lower screening panels 41 and the adjustment panel 42 to each other. It is very convenient. By changing the diameter of the screening hole, the selection requirements of different seeds can be met.
