Detailed Implementation
[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1:
[0038] Please see Figure 1-3As shown, this utility model is a fruit harvesting device, including a fruit-cutting head 1, a turning connector 2, a fruit conveying bag tube 3, and several handles 4 with threaded connections at both ends. The fruit conveying bag tube 3 is mounted on the fruit-cutting head 1 via steel hoops 5. The upper end of the fruit conveying bag tube 3 is a conical bag, and the lower end of the conical bag is connected to a straight bag. The turning connector 2 includes a connecting rod handle 6, a clamping hinge seat 7, and a clamping force-applying component 8. The connecting rod handle 6 and the clamping hinge seat 7 are clamped and fixed together by the clamping force-applying component 8. The angle between the connecting rod handle 6 and the clamping hinge seat 7 is adjustable from 30° to 180°. Multiple handles 4 are mounted on the clamping hinge seat 7, and the number of handles 4 can be increased or decreased according to the height of the target fruit.
[0039] Among them, such as Figure 3 , Figure 5 and Figure 9-11 As shown, the connecting rod handle 6 includes a semi-threaded rod body 61 threadedly connected to the first internal threaded connector 97. A single ear plate 62 is fixed to the end of the semi-threaded rod body 61. When the semi-threaded rod body 61 is fully screwed into the first internal threaded connector 97, the single ear plate 62 is perpendicular to the upper surface of the annular plate 93. The clamping hinge 7 includes a rectangular block 71. A double ear plate 72 is fixed to the top surface of the rectangular block 71. A rubber gasket 73 is fixed to the opposite inner wall of the double ear plate 72. The single ear plate 62 is placed between the two rubber gaskets 73. A first threaded post head 74 that mates with the internal threaded blind hole 41 at the upper end of the handle rod 4 is fixed to the bottom surface of the rectangular block 71. A second threaded post head 42 is fixed to the lower end of the handle rod 4. The clamping force application assembly 8 includes a threaded hand-tightening bolt 81 and a hand-tightening nut 82. The hand-tightening bolt 81 and hand-tightening nut 82 of the clamping force application component 8 can be manually tightened or loosened to adjust the clamping force between the connecting rod handle 6 and the clamping hinge seat 7, making it convenient to adjust the included angle between the connecting rod handle 6 and the clamping hinge seat 7.
[0040] Adjust the angle between the connecting rod handle 6 and the clamping hinge 7 according to the specific location of the fruit. For example, for fruit close to the trunk, adjust the angle between the connecting rod handle 6 and the clamping hinge 7 to a near right angle, and move the fruit-cutting head 1 horizontally when cutting the fruit stalk. For fruit on lower branches, adjust the angle between the connecting rod handle 6 and the clamping hinge 7 to an acute angle, and push or swing the handle rod 4 upwards when cutting the fruit stalk, so that the fruit-cutting head 1 cuts the fruit stalk obliquely upwards or horizontally. For fruit on higher branches, adjust the angle between the connecting rod handle 6 and the clamping hinge 7 to an obtuse angle, and pull down or swing the handle rod 4 when cutting the fruit stalk, so that the fruit-cutting head 1 cuts the fruit stalk obliquely downwards or horizontally. The turning connector 2 facilitates the adjustment and fixing of the clamp between the fruit-cutting head 1 and the handle rod 4, so as to carry out harvesting operations for fruits in different positions and improve the harvesting efficiency.
[0041] Among them, such as Figure 2 , Figure 4 and Figure 6-8As shown, the fruit-cutting head 1 includes a fruit-cutting connector 9 and an internal toothed cutting ring 10, a rubber ring plate 11, and a rubber ring 12, which are fixed to the fruit-cutting connector 9 by multiple sets of bolts and nuts. The fruit-cutting connector 9 includes an inner cylinder 91. A flange ring 92 is fixed to the inner wall of the inner cylinder 91. The internal toothed cutting ring 10 is installed above the flange ring 92. The rubber ring plate 11 is installed above the internal toothed cutting ring 10. The rubber ring 12 is installed below the flange ring 92. A ring plate 93 is fixed to the outer wall of the flange ring 92. A downwardly extending outer cylinder 94 is fixed to the outer wall of the ring plate 93. A limit ring 95 is fixed to the outer wall of the lower end of the outer cylinder 94. The upper end of the fruit conveying bag cylinder 3 is fixed to the outer wall of the outer cylinder 94 by a steel hoop 5. An L-shaped plate 96 extending to the outside is fixed to the upper surface of the ring plate 93. A first internal threaded connector 97 is fixed to the outer side of the L-shaped plate 96.
[0042] The internal toothed cutting ring blade 10 has an overall annular structure, with its inner ring surface featuring continuous toothed cutting teeth. The internal toothed cutting ring blade 10 is coaxially arranged with the rubber ring plate 11, and the axial orthogonal projection of the rubber ring plate 11 covers the internal toothed cutting ring blade 10. The internal toothed cutting ring blade 10 uses continuous internal cutting teeth to cut the fruit stem, facilitating the insertion of the fruit stem into the V-shaped cutting edge formed by adjacent cutting teeth. This prevents the fruit stem from slipping and allows the V-shaped cutting edge to quickly and effectively cut the fruit stem. The rubber ring plate 11 is positioned above the internal toothed cutting ring blade 10, effectively preventing the internal toothed cutting ring blade 10 from accidentally damaging the fruit during the fruit-attaching process of the fruit-attaching connector 9.
[0043] The rubber ring 12 has a chamfered inner edge at its lower end. Six rectangular grooves 121 are formed on the lower surface of the rubber ring 12. A U-shaped slot 122 is formed on the bottom surface of each rectangular groove 121. The rubber ring 12 is placed between the fruit and the branch to prevent the outer wall of the fruit from contacting the fruit-attaching connector 9. Simultaneously, the rubber ring 12, combined with the fruit-attaching connector 9 attached to the branch, can tighten the fruit stalk for easy and quick cutting.
