Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of screening devices, specifically relating to a seed production screening device. Background Technology
[0002] Precise size grading of seeds is crucial in seed production. A screening process is included in seed production to improve seed purity and ensure uniform seed size. This process removes impurities such as soil, stones, and fragments of stems and leaves, as well as substandard seeds like shriveled, broken, and diseased seeds, ensuring all seeds are of the same size. The seed screening process typically uses a vibrating screen. The principle of a vibrating screen is to use the mechanical vibration of a vibrating motor to cause the screen box containing the screen mesh to vibrate regularly, thus causing the seed material to move directionally on the screen surface, achieving the purpose of grading and screening. Document CN222901815U discloses a coal mine screening device, which also discloses the principle of vibrating motor driving the screen box and screen mesh for screening.
[0003] When traditional vibrating screens screen seed materials, the seed materials are fed from the feed hopper and fall onto the screen surface inside the screen box. If the seed materials stay on the screen surface for too long, local accumulation can occur, which can easily lead to blockage. In addition, if the seed materials flow unevenly on the screen surface, that is, if the seed materials are not completely dispersed on the screen surface, congestion can occur, resulting in a decrease in screening accuracy. The vibrating screen design does not have a disturbance design to move the locally accumulated seed materials on the screen surface, which is a shortcoming.
[0004] Existing vibrating screens for screening seed materials have the problem that they lack a disturbance design to move locally accumulated seed materials on the screen surface. To address this, this application proposes a seed production screening device. Utility Model Content

Detailed Implementation
[0027] 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.
[0028] Please see Figures 1 to 6This utility model provides a technical solution: a seed production screening device, including a vibrating screen device, comprising a screening support 11, a screening box 12, a vibrating motor 13 fixed to the screening box 12 by bolts, a screen 14 installed inside the screening box 12, and a feed hopper 2 communicating with the inside of the screening box 12. Seed material is poured into the feed hopper 2 and falls onto the screen 14. When the vibrating motor 13 runs, the screening box 12 and the screen 14 vibrate, causing the seed material on the screen 14 to move, thereby achieving the purpose of screening the seed material; the screen 14 is fixed to the screen by bolts. The fixed material distribution assembly includes a fixed plate 3 and a guide plate 4 fixed by screws, and a first round rod 5 installed between the opposing surfaces of the fixed plate 3. Seed material is poured in from the feed hopper 2 and falls onto the guide plate 4 inside the fixed plate 3. The first round rod 5 disperses the seed material, which rolls down on the guide plate 4. The bottom end of the guide plate 4 is stepped, causing the seed material to bounce at the bottom end of the guide plate 4, thus achieving the purpose of dispersing the seed material. Side plates 6 are fixed to the end of the fixed plate 3 by screws. The side plates 6 are distributed between the side of the screen 14 and the inner wall of the screening box 12. The side plate 6 serves to block the seed material, preventing it from clogging the gap between the side of the screen 14 and the inner wall of the screening box 12. The material agitation assembly includes a connecting rubber plate 71 fixed to the guide plate 4 by screws, a connecting rope 72 with one end glued to the connecting rubber plate 71, a rubber vibrating ball 73 fixed to the other end of the connecting rope 72, a second round rod 75 installed between opposing side plates 6, and a connecting spring 74 installed between the corresponding rubber vibrating ball 73 and the second round rod 75. The rubber vibrating ball 73 is positioned relative to the screen. 14. When the screen 14 vibrates, the rubber vibrating ball 73 vibrates accordingly. The vibrating rubber vibrating ball 73 drives the connecting rope 72 to shake. The shaking connecting rope 72 disturbs the seed material on the surface of the screen 14, preventing the seed material from accumulating locally on the surface of the screen 14 and causing blockage. The connecting spring 74 plays the role of fixing the rubber vibrating ball 73. When the rubber vibrating ball 73 bounces, the connecting spring 74 deforms and generates elastic force. The elastic force of the deformed connecting spring 74 acts on the rubber vibrating ball 73, so that the rubber vibrating ball 73 always adheres to the screen 14.
[0029] In this embodiment, the outer surface of the first round rod 5 is connected by an alternating connecting rod 51 through a threaded connection, and the connecting rod 51 serves to disperse the seed material.
[0030] In this embodiment, the guide plate 4 includes an inclined plate d and a stepped plate e. The connecting rubber plate 71 is connected to the stepped plate e. When the seed material falls on the surface of the guide plate 4, it rolls down under the action of gravity and vibration. When the seed material is at the bottom of the guide plate 4, it bounces and disperses.
[0031] In this embodiment, the side plate 6 includes a vertical plate a, a bottom plate b, and a curved plate c. The vertical plate a and the bottom plate b are perpendicular to each other. The two ends of the side plate 6 are welded to the vertical plate a and the bottom plate b, respectively. The side plate 6 plays a blocking role, blocking the seed material and preventing the seed material from accumulating on the side of the screen 14 and causing blockage.
[0032] In this embodiment, the second round rod 75 is perpendicular to the side plate 6, the second round rod 75 and the first round rod 5 are parallel to the connecting rubber plate 71, the connecting spring 74 is wavy, the connecting rope 72 is parallel to the screen 14, the wavy connecting spring 74 can deform, and the deformed connecting spring 74 will generate an elastic force to reset the rubber vibrating ball 73.
[0033] In this embodiment, the inside of the feed hopper 2 is provided with alternating distribution plates 21. The surface of the distribution plates 21 is vertically provided with distribution rods 22. When the seed material is poured into the feed hopper 2, some of the seed material falls on the surface of the distribution plates 21, some of the seed material is dispersed by the distribution rods 22, and some of the seed material leaks down from the first trough f and the second trough g, thereby achieving the purpose of dispersing the seed material. The distribution plates 21 and the distribution rods 22 play the role of dispersing the seed material. The distribution plates 21 are in an inclined state, and the surface of the distribution plates 21 is provided with the first trough f and the second trough g, which are connected.
[0034] Working principle and usage process of this utility model:
[0035] The seed material is poured into the feed hopper 2 and falls onto the screen 14. When the vibrating motor 13 runs, the screening box 12 and the screen 14 vibrate, causing the seed material on the screen 14 to move, thereby achieving the purpose of screening the seed material.
[0036] The seed material is poured in from the feed hopper 2. Some of the seed material falls on the surface of the distribution plate 21, some of the seed material is dispersed by the distribution rod 22, and some of the seed material leaks down from the first trough f and the second trough g, so as to achieve the purpose of dispersing the seed material. The distribution plate 21 and the distribution rod 22 play the role of dispersing the seed material.
[0037] The seed material falls onto the guide plate 4 inside the fixed plate 3, and the first round rod 5 and the connecting rod 51 disperse the seed material.
[0038] The seed material rolls down on the guide plate 4, and the bottom of the guide plate 4 is stepped. The seed material jumps at the bottom of the guide plate 4 to achieve the purpose of dispersing the seed material.
[0039] Seed material falls onto screen 14, and rubber vibrating ball 73 is in contact with screen 14. When screen 14 vibrates, rubber vibrating ball 73 vibrates with screen 14. The vibrating rubber vibrating ball 73 drives the connecting rope 72 to shake. The shaking connecting rope 72 disturbs the seed material on the surface of screen 14, preventing the seed material from accumulating locally on the surface of screen 14 and causing blockage.
[0040] The side plate 6 serves as a barrier, blocking the seed material and preventing it from accumulating on the sides of the screen 14 and causing blockage.
[0041] In summary: The vibrating screen 14 of this application has a disturbance design to agitate locally accumulated seed material. The seed material entering from the feed hopper 2 is dispersed by the first round rod 5 and the connecting rod 51. The seed material rolls down on the guide plate 4 and disperses. The rubber vibrating ball 73 vibrates with the screen 14. The vibrating rubber vibrating ball 73 drives the connecting rope 72 to shake. The shaking connecting rope 72 disturbs the seed material on the surface of the screen 14, avoiding local accumulation of seed material on the surface of the screen 14 and thus preventing blockage.
[0042] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
