[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0029] like Figures 1 to 6 As shown, the corn ear picking device of the embodiment of the utility model includes a conveying component 100, a stem pulling component 200, an ear picking component 300 and a stem blocking rod. The conveying component 100 includes a first conveying component 1 and a second conveying component 2. The first conveying component 1 and the second conveying component 2 are arranged at intervals in the left and right directions to form a conveying channel. The conveying component 100 is used to convey corn stalks 500 along the conveying channel. The stem pulling component 200 is located at the rear end of the conveying component 100. The stem pulling component 200 is used to grab the corn stalks 500. In the conveying direction of the corn stalks 500, the ear picking component 300 is located upstream of the stem pulling component 200. The ear picking component 300 is rotatable relative to the conveying component 100 to remove the corn ears on the corn stalks 500. The stem blocking rod is located above the conveying component 100. In the conveying direction of the corn stalks 500, the stem blocking rod is located upstream of the ear picking component 300.

[0030] Specifically, Figure 1As shown, the first conveying component 1 and the second conveying component 2 extend in the front-to-back direction and are arranged at intervals in the left-to-right direction to form a conveying passage, the stem pulling component 200 is located at the rear end of the conveying component 100, the ear picking component 300 is located in front of the stem pulling component 200 and above the conveying component 100, and the stem blocking stalk 400 is located in front of the ear picking component 300 and above the conveying component 100. The height of the stem blocking stalk 400 is substantially the same as that of the ear picking component 300.

[0031] The corn ear picking device of the embodiment of the utility model is provided with a stem blocking device 400. When the vertical corn stalks 500 pass through the stem blocking device 400, the stalks 500 can be blocked. As the conveying component 100 conveys the stalks 500 backwards, the corn stalks 500 are slowly laid down, thereby ensuring that the roots of the corn stalks 500 are grasped by the stem pulling component 200, which can improve the stem pulling effect and the ear picking quality.

[0032] In some embodiments, the first conveying component 1 and the second conveying component 2 both include a conveying arm 21 and a conveying chain. The conveying arm 21 is connected to the frame. A conveying groove 211 is provided on the conveying arm 21. The conveying chain is wound around the conveying arm 21, and the conveying chain is located in the conveying groove 211. The conveying chain is rotatable relative to the conveying arm 21.

[0033] Specifically, Figure 3 As shown, the conveying arm 21 extends in the front-to-back direction, and the side of the conveying arm 21 has a conveying groove 211, and the conveying groove 211 surrounds the outer wall of the conveying arm 21. The conveying chain is located in the conveying groove 211, and the rear end of the conveying chain has a sprocket 8, and the sprocket 8 is mounted on the rotating shaft of the pulling stem assembly 200, that is, when the pulling stem assembly 200 rotates, the sprocket 8 is driven to rotate, thereby driving the conveying chain to rotate. By opening the conveying groove 211 on the conveying arm 21 and placing the conveying chain in the conveying groove 211, the space utilization rate can be improved.

[0034] In some embodiments, the stem assembly 200 includes a first stem component and a second stem component, which are spaced apart in the up and down directions, and the conveying assembly 100 is located between the first stem component and the second stem component.

[0035] Specifically, Figure 4 As shown, the first stem pulling component and the second stem pulling component are respectively located at the upper and lower ends of the conveying component 100 and are arranged symmetrically. By setting the first stem pulling component and the second stem pulling component, the accuracy of grasping the corn stalks 500 can be improved, thereby improving the effect of picking ears.

[0036] In some embodiments, the first stem pulling component includes a first stem pulling roller 31 and a second stem pulling roller 32 , which are arranged at intervals in the left-right direction and are rotatable relative to the conveying arm 21 .

[0037] The second stem pulling component includes a third stem pulling roller 41 and a fourth stem pulling roller 42, which are arranged at intervals in the left and right directions, and are rotatable relative to the conveying arm 21, and the third stem pulling roller 41 is coaxially arranged with the first stem pulling roller 31, and the fourth stem pulling roller 42 is coaxially arranged with the second stem pulling roller 32.

[0038] Specifically, Figure 4 As shown, the first stem pulling roller 31 and the third stem pulling roller 41 share a rotating shaft and are coaxially arranged, the second stem pulling roller 32 and the fourth stem pulling roller 42 share a rotating shaft and are coaxially arranged, the first stem pulling roller 31 and the second stem pulling roller 32 are located above the conveying assembly 100, the third stem pulling roller 41 and the fourth stem pulling roller 42 are located below the conveying assembly 100, the first stem pulling roller 31 and the third stem pulling roller 41 are symmetrically arranged in the up and down directions, and the second stem pulling roller 32 and the fourth stem pulling roller 42 are symmetrically arranged in the up and down directions.

[0039] In some embodiments, the outer wall surfaces of the first stem pulling roller 31, the second stem pulling roller 32, the third stem pulling roller 41 and the fourth stem pulling roller 42 are all provided with thorns 421. By providing the thorns 421 on the outer wall surfaces of the stem pulling rollers, the straw 500 can be grasped more stably.

[0040] In some embodiments, the ear picking assembly 300 is located above the conveying arm 21, and the ear picking assembly 300 includes a first ear picking roller 5 and a second ear picking roller 6. The first ear picking roller 5 and the second ear picking roller 6 are arranged at intervals in the left and right directions to form an ear picking channel, and the ear picking channel is connected to the conveying channel. The first ear picking roller 5 and the second ear picking roller 6 are rotatable relative to the conveying arm 21.

[0041] Specifically, Figure 1 and Figure 5 As shown, the first ear picking roller 5 and the second ear picking roller 6 are both located above the conveying assembly 100, and the first ear picking roller 5 and the second ear picking roller 6 are symmetrically arranged in the left-right direction, and the first ear picking roller 5 and the second ear picking roller 6 are located in front of the third stem pulling roller 41 and the fourth stem pulling roller 42.

[0042] By providing the first ear picking roller 5 and the second ear picking roller 6 , when the corn ears on the corn stalks 500 pass through the ear picking passage, the first ear picking roller 5 and the second ear picking roller 6 can remove the corn ears on the corn stalks 500 .

[0043] In some embodiments, the spacing distance between the first ear picking roller 5 and the second ear picking roller 6 in the left-right direction is adjustable.

[0044] For example, the upper and lower ends of the first ear picking roller 5 and the second ear picking roller 6 are provided with a fixing plate 9, and the fixing plate 9 has a slide groove extending in the left and right direction. The upper and lower ends of the first ear picking roller 5 and the second ear picking roller 6 are respectively fixed in the slide groove on the fixing plate 9. When it is necessary to adjust the spacing distance between the first ear picking roller 5 and the second ear picking roller 6 in the left and right direction, the position of the first ear picking roller 5 and the second ear picking roller 6 in the slide groove can be adjusted, thereby adjusting the spacing distance between the first ear picking roller 5 and the second ear picking roller 6 in the left and right direction, and then adjusting the width of the ear picking channel in the left and right direction, so as to realize the ear picking operation of corn of different sizes.

[0045] In some embodiments, the first ear picking roller 5 and the second ear picking roller 6 are covered with a flexible buffer sleeve 7 on the outside.

[0046] For example, the flexible buffer sleeve 7 is a rubber sleeve.

[0047] By covering the outside of the ear picking roller with a flexible buffer sleeve 7, the impact force of the ear picking roller on the corn cobs during the ear picking process is reduced, the damage to the corn cobs is reduced, and the quality of ear picking is improved. In addition, the flexible buffer sleeve 7 can increase the damping coefficient, thereby extending the collision contact time between the corn cobs and the ear picking roller, thereby improving the effect of ear picking.

[0048] Combine the following Figures 1 to 6 The operation process of the ear picking assembly 300 according to the embodiment of the utility model is described.

[0049] The cut corn stalks 500 are clamped by the conveying chain and conveyed from front to rear through the conveying channel. When the stalks 500 come into contact with the stalk blocking 400, since the height of the stalks 500 is higher than the stalk blocking 400, the stalk blocking 400 blocks the stalks 500 and causes the stalks 500 to be laid down. At this time, the lower end of the stalks 500 is conveyed backward, and the entire stalks 500 presents a forward tilted posture. As the stalks 500 continue to move backward, the lower end of the stalks 500 is first pulled by the third pulling roller 41 and the first pulling roller 42. The four stem pulling rollers 42 grab and continue to transport backwards. As the third stem pulling roller 41 and the fourth stem pulling roller 42 continue to rotate, the corn stalks 500 continue to be pulled backwards. At this time, due to the presence of the stem blocking roller 400, the height of the corn stalks 500 continues to decrease. At this time, the lower end of the corn stalks 500 presents an upward moving posture, and is finally grabbed by the first stem pulling roller 31 and the second stem pulling roller 32 and continues to move backwards driven by the first stem pulling roller 31 and the second stem pulling roller 32.

[0050] And in the process of the stalk 500 continuously moving backward, since the corn cob protrudes out of the corn stalk 500, the corn cob collides and rubs against the first ear picking roller 5 and the second ear picking roller 6. In other words, the first ear picking roller 5 and the second ear picking roller 6 block the corn cob, so that the corn cob is peeled off, achieving the effect of corn picking.
