[0025] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0026] Reference Figure 1-5 , a seed grading machine for wheat seed cultivation: it includes a wheat seed screening box 1, a discharge cone bucket 6 is fixedly installed on the upper side of the wheat seed screening box 1, a mounting seat 7 is fixedly installed on the upper side of the discharge cone bucket 6, an electric telescopic rod 8 is fixedly installed on the upper side of the mounting seat 7, and a grading screening mechanism 9 is arranged inside the wheat seed screening box 1; the grading screening mechanism 9 includes a mounting groove 91, a plurality of slide grooves 92 are opened inside the mounting groove 91, a grading mesh plate 93 is slidably installed inside the slide groove 92, a rotating shaft 96 is symmetrically installed on both sides of the mounting groove 91, a bearing seat 98 is provided on the outside of the rotating shaft 96, a plurality of springs 97 are fixedly connected between the outside of the rotating shaft 96 and the inside of the bearing seat 98, and the bearing seat 98 is rotatably mounted on the inner wall of the wheat seed screening box 1, a mounting plate 99 is screwed on the rear side of the mounting groove 91, and a vibration motor 910 is fixedly mounted on the mounting plate 99.

[0027] In this method, an ear plate 911 is provided on the upper side of the mounting plate 99, and the ear plate 911 is fixedly installed on the rear side of the mounting groove 91. A vertical spring 912 is fixedly installed on the upper side of the ear plate 911. The output end of the electric telescopic rod 8 slides through to the lower side of the unloading cone hopper 6 and the output end of the electric telescopic rod 8 is fixedly connected to the upper end of the vertical spring 912. The mesh size of the grading mesh plate 93 decreases from top to bottom.

[0028] By the arrangement in the above manner, the mesh openings of the grading mesh plate 93 decrease from top to bottom, and thus the particle size of the wheat seeds passing through the grading mesh plate 93 decreases step by step.

[0029] In this method, a guide plate 94 is provided on the lower side of the grading mesh plate 93. The guide plate 94 is fixedly installed on the inner side of the mounting groove 91 and is tilted. A plurality of grading discharge ports 4 are opened on the left side of the wheat seed screening box 1. A discharge plate 5 is fixedly installed on the inner side of the grading discharge port 4. The discharge plate 5 is tilted. The discharge plate 5 corresponds to the guide plate 94 one by one, and the inner end of the discharge plate 5 is located directly below the guide plate 94.

[0030] Through the above-mentioned arrangement, the guide plate 94 will slide and guide the wheat seeds filtered out from the grading mesh plate 93 to the inner end of the outer discharge plate 5, and then the graded and selected wheat seeds will be sequentially guided to the outside of the wheat seed screening box 1 through the discharge plate 5.

[0031] In this embodiment, a telescopic limiting cylinder 95 is installed at the front end of the slide groove 92 , and an internal spring 913 is installed inside the telescopic limiting cylinder 95 .

[0032] Through the above-mentioned arrangement, the rebound force of the internal spring 913 inside the telescopic limit cylinder 95 pushes the telescopic limit cylinder 95 upward, limiting the front end of the slide groove 92 to prevent the grading mesh plate 93 from slipping off the front side of the slide groove 92.

[0033] In this embodiment, a bottom discharge port 10 is provided at the bottom right side of the wheat seed screening box 1 , and a slide plate 11 is fixedly installed at the bottom inner side of the wheat seed screening box 1 , and the slide plate 11 extends obliquely to the outside of the bottom discharge port 10 .

[0034] Through the above-mentioned arrangement, after the wheat seeds are filtered and screened by the grading mesh plates 93 at each level, the wheat seeds with the smallest graded particle size slide onto the slide plate 11, and subsequently the wheat seeds with the smallest particle size slide out from the bottom discharge port 10 on the right side of the wheat seed screening box 1 to the outside of the wheat seed screening box 1.

[0035] In this embodiment, a pad 2 is installed at the bottom of the wheat seed screening box 1, and the pad 2 is a rubber pad.

[0036] Through the above-mentioned arrangement, the arrangement of the rubber pad of the pad 2 has a certain vibration reduction effect on the wheat seed screening box 1.

[0037] In this embodiment, a controller 3 is fixedly mounted on the side wall of the wheat seed screening box 1 .

[0038] Through the above-mentioned configuration, the controller 3 can control the coordinated operation of the electrical components of the present invention, thereby improving the degree of automation of the present invention and accelerating the grading and screening rate of wheat seeds.

[0039] The working principle of the seed grading machine for wheat seed cultivation provided by the utility model is as follows:

[0040] When in use, the wheat seeds are added from the discharge cone hopper 6 to the inner side of the wheat seed screening box 1, and the vibration motor 910 is started, and the wheat seeds fall onto the grading mesh plate 93. Under the action of the vibration motor 910, the vibration of each grading mesh plate 93 is driven. Under the action of vibration, the grading mesh plates 93 at each level perform grading and screening on the wheat seeds. The particle size of the wheat seeds screened by each grading mesh plate 93 is gradually reduced and slides from the guide plate 94 on the lower side of each grading mesh plate 93 to the discharge plate 5. The discharge plate 5 guides the wheat seeds of each particle size to the small grading mesh plate through each grading discharge port 4. On the outside of the wheat seed screening box 1, the wheat seeds with the smallest particle size finally slide onto the slide plate 11. Under the action of the inclined surface of the slide plate 11, the wheat seeds are guided to the outside of the bottom discharge port 10 on the right side of the wheat seed screening box 1. In the later stage of the grading work, in order to prevent wheat seeds from remaining on each grading mesh plate 93, the electric telescopic rod 8 is started to contract, driving each grading mesh plate 93 to tilt toward the discharge plate 5. Under the action of vibration, the wheat seeds remaining on the grading mesh plate 93 slide and are guided onto the discharge plate 5, and finally guided to the outside of the wheat seed screening box 1, thereby avoiding wheat seed residue and enhancing the practicality of the present utility model.

[0041] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
