The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0025] This utility model embodiment provides a discharge structure for a corn seed thresher, such as... Figs. 1-4 As shown, the device includes a first support leg 1 and a second support leg 2. The bottom end of the first support leg 1 is flush with the bottom end of the second support leg 2, and the top end of the first support leg 1 is higher than the top end of the second support leg 2. A feeding trough 3 is installed on the inner top of the first support leg 1 and the second support leg 2. The feeding port of the feeding trough 3 is connected to the feeding port of the thresher. Reinforcing rods 4 are welded between the two first support legs 1, the two aligned first support legs 1 and the second support leg 2, and the two second support legs 2. The reinforcing rods 4 are located below the feeding trough 3. A swing arm mechanism is rotated on the two reinforcing rods 4 distributed along the length direction. A material blocking mechanism is slidably installed on the two second support legs 2, extending through to the top of the bottom plate of the feeding trough 3. The swing arm mechanism is used to push the material blocking mechanism in the unloaded state to move upward. The upwardly moving material blocking mechanism is used to prevent corn kernels from falling along the bottom plate of the feeding trough 3.
[0026] In the embodiment, firstly, after the corn is threshed, the corn is discharged from the discharge port of the thresher into the discharge chute 3 and slides down along the inclined surface of the bottom plate of the discharge chute 3, at this time, the receiving frame placed on the blocking mechanism is used to receive the corn kernels, when the receiving frame is about to be full, the receiving frame is separated from the blocking mechanism by lifting, at this time, the blocking mechanism is not subjected to the gravity of the receiving frame, at this time, the swing arm mechanism is rotated, the rotating swing arm mechanism drives the blocking mechanism to move upward, the blocking mechanism moves upward, so that the corn kernels sliding down are blocked, and the corn kernels are prevented from directly falling to the ground.
[0027] Then, a new empty receiving frame is placed on the blocking mechanism, at this time, the receiving frame is pressed down under the gravity, the swing arm mechanism is reset, and the blocking mechanism is reset downward, at this time, the blocking mechanism cannot block the corn kernels, and the corn kernels slide down again along the bottom plate of the discharge chute 3 into the receiving frame.
[0028] As shown in the further preferred embodiment of the utility model, Figs. 1-4 The swing arm mechanism comprises a fixed shaft 5, the fixed shaft 5 is fixedly connected between the two reinforcing rods 4, the outer wall of the fixed shaft 5 is rotatably installed with a swing arm 6, the center of the fixed shaft 5 to one end of the swing arm 6 is a short arm, the center of the fixed shaft 5 to the other end of the swing arm 6 is a long arm, one end of the short arm is fixedly installed with a counterweight 7, and one end of the long arm is in contact with the blocking mechanism.
[0029] In the embodiment, the swing arm mechanism utilizes the different lengths of the long arm and the short arm, so that the counterweight 7 and the short arm part can be rotated upward by a smaller force, and when the blocking mechanism is empty, the short arm and the counterweight 7 are rotated downward to reset, so that the blocking mechanism is lifted upward, and the corn kernels are prevented from sliding to the ground.
[0030] As shown in the further preferred embodiment of the utility model, Figs. 1-4 The blocking mechanism comprises a supporting plate 8, one side of the supporting plate 8 is integrally formed with a blocking plate 9, the top of the blocking plate 9 is integrally formed with an anti-falling plate 10, the top end surface of the anti-falling plate 10 in the lowest position is flush with the top end surface of the bottom plate of the discharge chute 3, the width of the blocking plate 9 is less than the end of the supporting plate 8, the width of the blocking plate 9 is equal to the distance between the two sides of the discharge chute 3, and the long arm of the swing arm 6 is in contact with the bottom end of the blocking plate 9.
[0031] In the embodiment, after the receiving frame is separated from the supporting plate 8, at this time, the supporting plate 8 is in an empty state, at this time, the long arm part of the swing arm mechanism is rotated upward, so as to push the blocking plate 9 and the supporting plate 8 to slide upward, the blocking plate 9 slides upward synchronously, driving the anti-falling plate 10 to slide upward, the corn kernels in the discharge chute 3 are blocked, so as to prevent the corn kernels from sliding down to the ground;
[0032] When the empty receiving frame is placed on the support plate 8, the support plate 8 receives the downward pressure of the receiving frame, and at this time, the rotation of the counterweight 7 from bottom to top is realized under the cooperation of the long arm of the swing arm mechanism, at this time, the support plate 8 is reset to the low point, and the blocking mechanism cancels the blocking of the corn kernels, and the discharging operation is performed again.
[0033] The design realizes the effects of automatic receiving and automatic blocking, and further manual intervention is not required.
[0034] As shown in the further preferred embodiment of the utility model, Figs. 1-4 The support plate 8 is integrally formed with the outwardly protruding sliding block 12 on the side close to the second supporting leg 2 and at the end of the blocking plate 9, and the sliding groove 11 for the upward and downward sliding of the sliding block 12 is formed on the second supporting leg 2.
[0035] In the embodiment, when the support plate 8 slides up and down, the sliding block 12 slides up and down along the sliding groove 11 under the driving of the support plate 8, and since the cross sections of the sliding block 12 and the sliding groove 11 are both convex structures, the problem of separation of the sliding block 12 and the sliding groove 11 can be effectively prevented, and the cooperation of the sliding block 12 and the sliding groove 11 provides the movement guide for the support plate 8.
[0036] As shown in the further preferred embodiment of the utility model, Figs. 1-4 The bottom plate of the discharging groove 3 is provided with the accommodating groove 13 for accommodating the anti-disengagement plate 10 and for the upward and downward sliding of the blocking plate 9, and the part of the anti-disengagement plate 10 close to the discharging port of the discharging groove 3 protrudes outward.
[0037] In the embodiment, the setting of the anti-disengagement plate 10 can avoid the misalignment of the blocking plate 9 and the accommodating groove 13, thereby avoiding the direct falling of the corn kernels from the position of the accommodating groove 13, and the protrusion of the anti-disengagement plate 10 towards the discharging port of the discharging groove 3 can ensure the smooth downward movement of the anti-disengagement plate 10 and prevent the incomplete resetting caused by the blocking of the corn kernels.
