Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural tools, in particular to a strawberry picking device. Background Art

[0002] In the existing strawberry picking process, it is usually necessary to bend over, which is labor-intensive and has low work efficiency, and is not conducive to picking and collecting strawberries.

[0003] For example, Chinese utility model CN209806476U discloses a strawberry picker, which drives the movable knife to move by gripping a movable grip, so that a shearing cut is formed between the movable knife and the fixed knife, and a shearing force is provided by a reset spring. When cutting the strawberry stems, the operator only needs to loosen the movable grip, so that the collecting bucket is not easy to shake, and the shearing device can cooperate with the strawberry stems more easily for cutting, making the operation easier.

[0004] However, in the above-mentioned prior art, the fixed knife and the movable knife need to protrude from the upper edge of the collecting bucket, so that in the process of adjusting the strawberry stem to be stuck between the fixed knife and the movable knife, it is very easy for the fixed knife and the movable knife to touch the strawberry, thereby causing damage to the strawberry, making the overall reliability and convenience of use poor.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] See also Figure 1 As shown, the utility model is a strawberry picking device, comprising a handle bar 1 which is the same as the prior art, a movable grip bar 2 which is rotatably connected to the upper end of the handle bar 1, and a driving rope 101 which is connected to the movable grip bar 2 at one end.

[0029] like Figure 2 and 3 As shown, the lower end of the handle bar 1 is connected to a collecting bucket 3. The collecting bucket 3 includes a circular ring frame 301, and a circular net basket or a net bag can be installed at the lower end of the circular ring frame 301 to receive the picked strawberries.

[0030] The outer wall of the annular frame 301 is connected to two connecting plates 302 by screws, and is connected to the handle bar 1 through the two connecting plates 302. The outer wall of the annular frame 301 is rotatably connected to a ring-shaped knife seat 4 and a rotating shaft 5.

[0031] Among them, the outer wall of the circular frame 301 is connected to a mounting block, the rotating shaft 5 is rotatably connected to the mounting block and passes through the mounting block, the axial direction of the rotating shaft 5 is set parallel to the axial direction of the circular frame 301, and the rotating shaft 5 is located at a position corresponding to the position of the handle rod 1.

[0032] The annular knife seat 4 is provided with a plurality of blades 401 along the circumferential direction, and the upper ends of the blades 401 are lower than the upper edge of the annular frame 301, and a rack 402 is fixedly connected to the outer wall of the annular knife seat 4. The blades 401 can be flexibly arranged according to the diameter of the annular frame 301, and the rack 402 is an arc structure arranged concentrically with the annular knife seat 4.

[0033] The rotating shaft 5 is sleeved with a torsion spring 501, and the end of the rotating shaft 5 is fixedly connected with a gear 502 meshing with the rack 402, and the driving rope 101 is wound around one end of the rotating shaft 5 located on the other side of the mounting block. The torsion spring 501 allows the rotating shaft 5 to rotate and reset itself after rotation.

[0034] The circular frame 301 is provided with a shearing notch 303 which is staggered with the blade 401, and the bottom of the shearing notch 303 is lower than the upper end of the blade 401, so as to ensure that the strawberry stem inserted into the shearing notch 303 can be cut by the blade 401. In addition, the upper end of the shearing notch 303 is opened into a trumpet structure, so that the strawberry stem can be inserted into the shearing notch 303 more easily.

[0035] When picking, hold the handle bar 1 and adjust the position of the collecting bucket 3 so that the strawberries are located inside the annular frame 301 and the strawberry stems connected to the strawberries are inserted into the cutout 303. At this time, the driving rope 101 is pulled by pressing the movable handle bar 2, and the driving rope 101 pulls the rotating shaft 5 to rotate.

[0036] like Figure 6 As shown, the gear 502 is meshed with the rack 402 to drive the annular knife seat 4 to rotate, so that the blade 401 moves to the cutting opening 303, and then cuts the strawberry stems, and after cutting, the strawberries fall into the collecting bucket 3. After the movable grip 2 is released, the shaft 5 is reversed under the action of the torsion spring 501, so that the annular knife seat 4 rotates and resets, that is, the blade 401 moves to one side of the cutting opening 303.

[0037] By setting the upper end of the blade 401 lower than the upper edge of the annular frame 301, it is avoided that the blade 401 easily touches the strawberry and causes damage to the strawberry, thereby effectively improving the overall reliability and convenience of use. At the same time, multiple blades 401 and cutting notches 303 are provided, so that the strawberry stem can be flexibly cut into any cutting notch 303 without deliberately adjusting the position, thereby greatly improving the convenience of picking.

[0038] like Figure 4 and 5 As shown, the upper side of the circular frame 301 has a flange 304 arranged outward, and the blade 401 is located in the gap between the circular frame 301 and the flange 304, which is used to shield the blade 401 so that the blade 401 is not exposed, further ensuring that the blade 401 will not touch the strawberry, thereby greatly improving the reliability of use.

[0039] Meanwhile, the annular frame 301 is a nylon ring or a metal ring, and the annular knife holder 4 is a nylon ring. If both the annular frame 301 and the annular knife holder 4 can be made of nylon rings, the overall weight can be effectively reduced to ensure ease of use.

[0040] Moreover, the angle between the axial direction of the annular frame 301 and the length direction of the handle bar 1 is 0-90°. As shown in the figure, the axial direction of the annular frame 301 is arranged parallel to the length direction of the handle bar 1, that is, the angle is 0°. At this time, a connecting shaft 102 is connected between the two connecting plates 302, and the connecting shaft 102 is rotatably connected to a guide groove wheel 103, which is used to support and guide the drive rope 101 through the guide groove wheel 103, so that the drive rope 101 can better pass through the inside of the handle bar 1.

[0041] When the axial direction of the circular frame 301 is set parallel to the length direction of the handle bar 1, or when it is set at a certain angle, it is more convenient to pick strawberries without bending over, which can provide better convenience during picking.

[0042] In the description of this specification, the description with reference to the terms "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
