Description

Technical Field

[0001] The utility model relates to the technical field of seed processing, and more specifically to a corn seed threshing device. Background Art

[0002] Most of the corn threshing equipment currently on the market cannot thresh the corn kernels step by step during threshing, resulting in the larger ends of the corn being squeezed and damaged.

[0003] The existing patent is a high-yield corn seed thresher, and the patent application number is CN 209930968 U. A conical cylinder is set, and the left end of the conical cylinder is larger than the right end. When the corn cob enters from the feed hopper, the corn cob is transferred from left to right under the action of the spiral propulsion teeth. During this period, the corn kernels are gradually threshed under the friction of the spiral propulsion teeth, and fall from the lower grain holes of the spiral propulsion teeth into the grain collecting chamber. When the corn cob moves to the right end of the conical cylinder, the threshing is completed, and the empty cob falls from the cob outlet. The equipment is easy to operate, has a high threshing completion rate, and the threshed corn kernels are highly complete.

[0004] However, in patent application number CN 209930968 U, corn kernels are gradually threshed under the friction of the spiral propulsion teeth and fall into the grain collecting chamber from the lower grain holes of the spiral propulsion teeth. Since the corn seeds after threshing cannot be screened, the broken seeds inside the corn seeds cannot be screened out. Therefore, we propose a corn seed threshing device to solve the above-mentioned problems. Utility Model Content

[0033] Example:

[0034] See also Figure 1-6 , a corn seed threshing device, comprising a chassis 1;

[0035] A threshing mechanism is installed on the top of the chassis 1;

[0036] The threshing mechanism includes a threshing cylinder 2 connected to the top edge of the chassis 1, a reduction motor 3 installed on the top of the threshing cylinder 2, a feeding cylinder 4 connected to the top side wall of the threshing cylinder 2, a cone cylinder 6 arranged on the inner side of the threshing cylinder 2 and connected to the power output end of the reduction motor 3, a spiral propulsion tooth 7 fixedly connected to the outer wall of the cone cylinder 6, and a convex tooth 5 fixedly connected to the inner wall of the threshing cylinder 2;

[0037] A screening assembly is installed on the inner side of the chassis 1;

[0038] The screening assembly includes a boss 8 symmetrically fixedly connected to the inner wall of the chassis 1 and arranged at an angle, a bracket 9 installed above the boss 8 and with the end extending to the outside of the chassis 1, a first screen 10, a second screen 11 and a third screen 12 installed on the inner side of the bracket 9 from top to bottom, a vibration motor 13 installed on the top of the bracket 9 through a bracket, a spring 14 connected to the boss 8 at one end and to the bracket 9 at the other end, a guide post 15 welded to the outer wall of the bracket 9, and a guide hole 16 opened on the side wall of the chassis 1 and matched with the guide post 15;

[0039] It should be noted that the big end of the corn cob to be separated is sent to the threshing cylinder 2 by corresponding the feeding cylinder 4 to the corn cob, and the cone cylinder 6 is driven to rotate by the reduction motor 3. The cone cylinder 6 has a small upper end and a large lower end, so that the corn cob is rubbed by the spiral propulsion teeth 7 and the convex teeth 5, so that the corn kernels fall off the corn cob, and the corn cob is conveyed downward at the same time, so that the threshing completion degree is high;

[0040] Corn kernels and corn cobs after threshing fall into the screening component under the action of gravity, and the vibration motor 13 works and the guide column 15 slides on the inner side of the guide hole 16 under the elastic action of the spring 14, so that the bracket 9 vibrates up and down, so that the first screen 10, the second screen 11 and the third screen 12 screen the corn kernels and corn cobs step by step, the first screen 10 intercepts the corn cobs, the second screen 11 intercepts the finished corn kernels, and the third screen 12 intercepts the corn kernel residues, and the boss 8 is set at an angle, so that the corn cobs, the finished corn kernels and the corn residues are screened, and the broken seeds inside the corn seeds can be screened out.

[0043] like Figure 3 As shown, the outer diameter of the cone 6 gradually increases from top to bottom;

[0044] It should be noted that, by utilizing the configuration of the cone 6 with a small upper end and a large lower end, the corn kernels are caused to fall off the corn cob under the action of the friction of the spiral propulsion teeth 7 and the convex teeth 5 on the corn cob, and the corn cob is simultaneously conveyed downward, so that the threshing completion degree is high.

[0049] like Figure 1 , Figure 5 , Figure 6 As shown, the guide hole 16 is arranged in a straight line structure, and the width of the guide hole 16 is adapted to the outer diameter of the guide post 15;

[0050] It should be noted that the stability of the bracket 9 during the up and down vibration process is ensured.

[0051] When in use: the big end of the corn cob to be separated is matched with the feeding cylinder 4 and is fed into the threshing cylinder 2, and the cone cylinder 6 is driven to rotate by the reduction motor 3, and the configuration of the cone cylinder 6 with a small upper end and a large lower end is utilized, so that the corn cob is rubbed by the spiral propulsion teeth 7 and the convex teeth 5, so that the corn kernels fall off the corn cob, and the corn cob is conveyed downward at the same time, so that the threshing completion degree is high;

[0052] Corn kernels and corn cobs after threshing fall into the screening component under the action of gravity, and the vibration motor 13 works and the guide column 15 slides on the inner side of the guide hole 16 under the elastic action of the spring 14, so that the bracket 9 vibrates up and down, so that the first screen 10, the second screen 11 and the third screen 12 screen the corn kernels and corn cobs step by step, the first screen 10 intercepts the corn cobs, the second screen 11 intercepts the finished corn kernels, and the third screen 12 intercepts the corn kernel residues, and the boss 8 is set at an angle, so that the corn cobs, the finished corn kernels and the corn residues are screened, and the broken seeds inside the corn seeds can be screened out.

[0053] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto.
