Detailed Description
Referring to fig. 1, a corn threshing device comprises a threshing cylinder 2, an outer cylinder 3, a material groove 4, a bracket 5 and a waste material groove 6.
The bracket 5 comprises a supporting leg and a table top, and a through hole for the threshing cylinder to pass through is arranged in the middle of the table top.
Referring to fig. 4 and 5, the material tank 4 is disposed on the top of the support 5. A convex circular truncated cone 41 is arranged in the middle of the bottom surface of the material groove 4, a through hole for the threshing cylinder 2 to pass through is formed in the upper bottom surface of the circular truncated cone, and a gap smaller than the size of normal corn kernels is formed between the threshing cylinder 2 and the through hole of the circular truncated cone 41.
The outer cylinder 3 is arranged in the material tank 4 through a plurality of fine brackets.
Referring to fig. 2 to 4, the threshing cylinder 2 is disposed inside the outer cylinder 3 and the outer wall thereof is connected to the outer cylinder 3 by a connecting member 26. The upper end of the threshing cylinder 2 is in a round table shape, the middle part and the lower end of the threshing cylinder 2 are in a cylindrical shape with the same inner diameter, and only parts of the upper end and the middle part of the threshing cylinder 2 are connected together. Threshing cylinder 2 of which the upper end is in a circular truncated cone shape comprises a right threshing half cylinder 21 and a left threshing half cylinder 22, wherein the tail ends of the right threshing half cylinder 21 and the left threshing half cylinder 22 are integrally designed, the front ends of the right threshing half cylinder 21 and the left threshing half cylinder 22 are separately arranged, connecting lugs 23 are respectively arranged at the front ends of the connected threshing half cylinders, and the two connecting lugs 23 are connected through a spring 24. The threshing ring is fixed on one side, the opening is formed in one side, the opening is connected through a spring, and the threshing cylinder 2 is convenient to adapt to corns with different sizes. The outer edge of the upper end of the threshing cylinder 2 is provided with a circle of saw teeth 25, and the sharp ends of the saw teeth 25 are convenient to insert corns for threshing. The upper end of the threshing cylinder 2 is in a round table shape, the middle part and the lower end are in a cylindrical shape, the inner diameter of the cylindrical shape is equal to the maximum inner diameter of the round table shape, and the threshed corns can conveniently slide down in the threshing cylinder 2.
The outer wall of the middle part of the threshing cylinder 2 is circumferentially provided with a circle of check ring 27, the check ring 27 is arranged on the table top of the circular table 41, and the threshing cylinder 2 passes through the through hole of the circular table 41 and then the check ring 27 is lapped on the table top of the circular table 41, so that the threshing cylinder 2 can be suspended above the waste material tank 6 and the discharge hole of the threshing cylinder 2 is not blocked. Meanwhile, the retainer ring 27 can further prevent the corn kernels from falling to the waste trough 6 from the gap of the through hole of the circular truncated cone 41.
The waste material groove 6 is arranged below the table surface of the bracket 5 and is positioned below the threshing cylinder 2.
In order to increase the downward force applied to the corn, a pressing block 1, a pressing rod 7 and a supporting seat 8 are also arranged. On the supporting seat 8 was fixed in the bottom surface, the supporting rod of pushing down stick 7 and 8 vertical directions of supporting seat rotated and is connected, and the connective bar of compact heap 1 upper end rotated with 7 tip of pushing down the stick and is connected. The rotating shafts between the pressing rods 7 and the supporting seat 8 and between the pressing rods 7 of the pressing block 1 are all parallel to the ground. The lower pressing rod 7 and the supporting seat 8 are installed on the principle of a lever, as long as a small upward force is applied to the lower pressing rod 7, the lower pressing rod 7 can apply a large force to the pressing block 1 at the other end so as to apply a downward force to the corn to press the corn downward, and grains are peeled under the action of the saw teeth 25 on the corn.
The working principle of the embodiment is as follows: the corn to be shelled is placed at the feed inlet of the threshing cylinder 2 (namely, the upper opening), the upper part of the threshing cylinder 2 is in a round table shape, so that the corn can be clamped at the feed inlet, and the upper edge of the threshing cylinder 2 is just positioned at the joint of the corncobs and the corn kernels. Downward force is applied to the corn through the pressing block 1, the saw teeth 25 on the upper edge of the threshing cylinder cut the corn kernels, and then the corn kernels are separated from the corn cobs and fall into the material groove 4. The outer barrel 3 can prevent the splashing of the corn kernels. Because the upper part of the threshing cylinder 2 is provided with the right threshing half cylinder 21 and the left threshing half cylinder 22 which are not connected, the half cylinders can be suitable for corns with different sizes after being extruded and separated. The corn after threshing enters a waste material groove 6 along a threshing cylinder 2. After threshing is finished, the threshing cylinder 2 and the outer cylinder 3 are taken down, and the corn kernels are taken out from the material groove 4.
