Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides: A rapeseed breeding threshing device, as Figures 1-4 shown, including a support bottom frame 1 and a threshing box 4 installed on the upper surface of the support bottom frame 1. Two groups of threshing barrels 13 are arranged inside the threshing box 4. A first screening plate 12 and a second screening plate 15 are arranged inside the threshing box 4 and below the two groups of threshing barrels 13. A guide roller 11 is rotatably arranged inside the threshing box 4 and above the second screening plate 15;

[0025] A screening assembly for secondary screening of rapeseed grains is arranged below the first screening plate 12 and the second screening plate 15;

[0026] The screening assembly includes a bottom screening plate 14 and two groups of pushing modules. A collection box 8 is slidably arranged inside the support bottom frame 1 and below the bottom screening plate 14.

[0027] Preferably, the two sets of pushing modules include electric push rods 3, support plates 7 and pushing plates 10. The two support plates 7 are symmetrically installed on both sides of the threshing box 4. The electric push rods 3 are fixedly installed inside the support plates 7, and the electric push rods 3 slide through the support bottom frame 1 and are fixedly connected to the pushing plates 10. The two pushing plates 10 are slidably arranged on the upper surface of the bottom sieve plate 14. By arranging the two support plates 7 to support the electric push rods 3, and driving the pushing plates 10 to move above the bottom sieve plate 14 through the electric push rods 3, the rapeseed above the bottom sieve plate 14 is driven to move back and forth under the action of the two pushing plates 10, thereby preventing the rapeseed on the upper surface of the bottom sieve plate 14 from being blocked, and ensuring that the rapeseed above the bottom sieve plate 14 can pass through the bottom sieve plate 14 and enter the collection box 8 inside.

[0028] Furthermore, clamping protrusions 18 are fixedly arranged on both sides of the collection box 8. The clamping protrusions 18 are arranged as convex blocks, and clamping grooves 19 corresponding to the two clamping protrusions 18 are opened inside the support bottom frame 1. The clamping protrusions 18 are arranged as convex blocks to ensure that the clamping protrusions 18 will not shift when moving along the clamping grooves 19, so as to ensure that the collection box 8 can move to directly below the bottom sieve plate 14 when it is pulled out and inserted again, and further ensure that the rapeseed falling from the bottom sieve plate 14 will enter the collection box 8 inside, thus facilitating the staff to collect and take the rapeseed.

[0029] Even further, the two threshing barrels 13 are connected through, and threshing rollers 16 are rotatably arranged inside the two threshing barrels 13. Two threshing motors 6 corresponding to the threshing rollers 16 are bolted to the side of the threshing box 4, and the two threshing motors 6 are key-connected to the corresponding threshing rollers 16. The threshing rollers 16 are existing threshing devices. Starting the threshing motors 6 drives the threshing rollers 16 to rotate, so as to thresh the rapeseed inside the threshing barrels 13, and arranging the two threshing barrels 13 improves the threshing efficiency of the rapeseed.

[0030] It should be noted that a feeding hopper 5 is provided through the upper part of one threshing barrel 13, a blanking plate 17 is provided through the lower part of the other threshing barrel 13, and grain outlet holes 20 are opened on the outer arc surfaces of the two threshing barrels 13. The feeding hopper 5 is arranged to facilitate the staff to put the rapeseed into the threshing barrels 13, and opening the grain outlet holes 20 enables some rapeseed to be directly discharged from the grain outlet holes 20 to above the first sieve plate 12 and the second sieve plate 15 during the threshing of the rapeseed by the threshing barrels 13.

[0031] Specifically, the first sieve plate 12 is inclined and arranged inside the threshing box 4, and the second sieve plate 15 is connected to the lower side of the first sieve plate 12. The first sieve plate 12 is inclined to guide the rapeseed falling from the blanking plate 17, ensuring that it can enter the stirring range of the guide rollers 11, and the rapeseed will fall onto the upper surface of the bottom sieve plate 14 through the first sieve plate 12 and the second sieve plate 15.

[0032] In addition, one side of the threshing box 4 close to the guiding roller 11 is connected with a waste outlet 2 in a penetrating manner. A driving motor 9 corresponding to the guiding roller 11 is bolted to the side surface of the threshing box 4. When the driving motor 9 is started, the guiding roller 11 is driven to rotate, and the guiding roller 11 drives the rape stalks, impurities, etc. to move towards the waste outlet 2 and be discharged through the waste outlet 2.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
