Description

Technical Field

[0001] The invention relates to the technical field of banana picking equipment, and in particular to a banana stem clamping device used for banana tuft cableway transportation. Background Art

[0002] Bananas are an important cash crop in my country and are also listed as a food crop by the Food and Agriculture Organization of the United Nations. Currently, post-harvest banana processing typically includes field harvesting, cableway transportation, combing, packaging, and sales. After cutting the banana buds from the trees in the field, banana farmers typically tie the ends (the thicker ends, where they connect to the trees) to a rope, which is then hung on a cableway built in the field for transport to the combing workshop. However, this method of tightening the banana stalks with ropes can lead to a loose grip on the stalks, causing the buds to fall off during transport, resulting in the stalks falling and the fruit being damaged. Furthermore, this method of clamping the banana stalks with ropes provides weak grip, making the lower part of the buds prone to swinging, causing adjacent buds to collide and swing during transport, resulting in fruit damage. This swinging also makes it easier for the stalks to break free from the ropes, increasing the risk of them falling and being lost. Furthermore, removing the ropes from the cableway and loosening the stalks before entering the combing workshop is a tedious task. Therefore, improving the stability and convenience of banana stem clamping and releasing during banana cableway transportation is an urgent problem to be solved. Summary of the Invention

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-8 The present invention is described in further detail.

[0027] like Figure 1 、 2 As shown, a banana stem clamping device for banana cob cableway transportation includes a frame 1 for fixing to the banana cob cableway. A through hole 11 is provided in the center of the frame 1 for passing the banana stem 8. The frame 1 is rotatably connected to an inner gear ring 2 concentric with the through hole 11. The inner gear ring 2 can rotate on the frame 1 with the through hole 11 as the center. Four slide grooves 12 are evenly distributed on the frame 1 along the circumference of the through hole 11. The slide grooves 12 are elongated and pass through the frame 1. Two adjacent slide grooves 12 are perpendicular to each other. Slide plates 3 are slidably connected to the slide grooves 12. The four slide plates 3 have the same shape and size.

[0028] like Figure 1-4As shown, the skateboard 3 includes a skateboard body 31 and a slider 32. The skateboard body 31 is polygonal. The slider 32 is fixed to the bottom of the skateboard body 31 and slidably arranged in the corresponding slide groove 12. The skateboard body 31 includes adjacent and mutually perpendicular sliding edges 311 and clamping edges 312. The clamping edge 312 is also adjacent to the driving edge 313. The driving edge 313 is parallel to the corresponding slide groove 12. A rack 3131 is provided on the driving edge 313 along the length direction. The sliding edge 311 of the skateboard body 31 slides in contact with the clamping edge 312 of the adjacent skateboard body 31. The clamping edges 312 of 31 fit and slide with the sliding edges 311 of the adjacent skateboard bodies 31, and the four skateboard bodies 31 fit and connect in sequence along the circumference of the through hole 11. The clamping edges 312 of the four skateboard bodies 31 form a square hole 4 concentric with the through hole 11. A gear 5 is provided between the inner gear ring 2 and the corresponding skateboard body 31. The gear 5 is engaged with the inner gear ring 2 and the rack 3131 of the corresponding skateboard body 31. A limiting portion is fixedly connected to the frame 1, and the inner gear ring 2 is located on the inner side of the limiting portion and is slidably adapted to the limiting portion. A driving portion for driving the inner gear ring 2 to rotate is provided on the frame 1.

[0029] like Figure 1 、 6 As shown, the limiting portion of this embodiment is an open ring 6, and an inwardly recessed annular groove 61 is provided at the bottom of the inner edge of the open ring 6 along the circumferential direction. The open ring 6 is concentric with the through hole 11 and is fixed to the frame 1 by screws.

[0030] like Figure 1 、 5 As shown, the bottom of the outer edge of the inner gear ring 2 is provided with an outwardly protruding stepped ring 21 along the circumferential direction. The stepped ring 21 is adapted to the ring groove 61. The outer edge of the stepped ring 21 is provided with an outward extending connecting block 211. The connecting block 211 is located at the opening of the open ring 6. The inner gear ring 2 can rotate in the open ring 6.

[0031] like Figure 1 As shown, the driving part of this embodiment is an electric push rod 7, the electric push rod 7 is hinged to the frame 1, and the telescopic rod of the electric push rod 7 is hinged to the connecting block 211.

[0032] like Figure 1 、 3 As shown in Figures 7 and 7, in this embodiment, the bottom center of the gear 5 is fixedly connected to a vertical axle 51, which passes through the frame 1 and is rotatably connected to the frame 1. The axle 51 passes through the center of the through hole 11 and the extension line of the vertical slide groove 12 passes through the axis of the axle 51.

[0033] A limit ring 511 is provided at the bottom of the wheel shaft 51 , and the wheel shaft 51 is screwed with a screw passing through the limit ring 511 . By providing the limit ring 511 , the gear 5 can be prevented from axial movement.

[0034] like Figure 4As shown, the slider 32 is long and fits in the slide groove 12. The slider 32 is embedded in the corresponding slide groove 12. A limit block 321 is provided at the bottom of the slider 32. The width of the limit block 321 is greater than the width of the slide groove 12. The limit block 321 is fixedly connected to the slider 32. By setting the limit block 321, the stability of the horizontal sliding of the slider 3 can be ensured, the slider 3 can be prevented from moving in the vertical direction and the slider 32 can be prevented from escaping from the slide groove 12.

[0035] like Figure 1 、 4 As shown, the slide body 31 of this embodiment is a quadrilateral, with a 45° angle between the clamping edge 312 and the driving edge 313. Side edges 314 are provided between the sliding edge 311 and the driving edge 313. Properly setting the side edges 314 based on the diameter of the inner gear ring 2 prevents interference between the slide body 31 and the inner gear ring 2 when the square hole 4 expands.

[0036] In one embodiment, in order to prevent impurities from entering the device and affecting its reliable operation, a disc-shaped outer cover (not shown in the figure) is fixed above the frame 1, and a receiving opening corresponding to the through hole 11 is provided in the center of the outer cover.

[0037] The frame 1 of this embodiment is a square plate, and mounting holes 13 are provided at the four corners of the frame 1 .

[0038] like Figure 8 As shown, the working process of the present invention is as follows:

[0039] The frame 1 is fixed to the banana stalk cableway and moves along the stalk cableway. During operation, a banana farmer inserts the thick end of a banana stalk cut from a banana tree into the through hole 11 of the frame 1 from bottom to top, then activates the electric push rod 7, which drives the inner ring gear 2 to rotate. The inner ring gear 2 synchronously drives the gear 5 to rotate, and the gear 5 drives the meshing rack 3131 to perform linear motion. The rack 3131 drives the corresponding slide plate 3 to slide along the chute 12. The four gears 5 drive the corresponding slide plates 3 to slide in a coordinated manner, thereby causing the square holes 4 formed by the clamping edges 312 of the four slide plate bodies 31 to expand or contract synchronously. When the square holes 4 contract, they can clamp the banana stems 8 in the through hole 11. The square holes 4 on the frame 1, holding the banana stems 8, are then transported to the combing workshop along the banana stalk cableway. The banana farmer then controls the electric push rod 7 to reverse the movement, causing the square holes 4 to expand. The banana farmer removes the banana stems 8 from the square holes 4, thus completing the unloading of the banana stalks.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
