Description

A nut collector Technical Field

[0001] The present invention relates to the technical field of nut collecting tools, and in particular to a nut collector. Background Art

[0002] When hazelnuts, chestnuts, walnuts, and almonds ripen, they fall from the trees and scatter on the ground nearby, requiring prompt collection and disposal. Manual collection is often used to collect scattered nuts on the ground. However, due to the large area and large number of nuts scattered, manual collection often requires a lot of physical effort from fruit farmers and is relatively inefficient.

[0003] To this end, a handheld picking device called a nut collector has appeared on the market, which allows fruit farmers to pick nuts without bending over. After searching, the nut picker in the prior art is shown in patent CN201621150771.X (authorization announcement number CN206149888U), which mainly includes a handle, a bracket connected to the handle and a collecting cage rotatably connected to the lower end of the bracket. A plurality of spring wires are installed on the collecting cage. The spring wires can be compressed and deformed, resulting in an increase in the gap between two adjacent spring wires, forming a feed port with an aperture larger than the diameter of the nuts, so that nuts scattered on the bottom surface can enter the collecting cage. The whole picking process is efficient, easy and convenient.

[0004] When the collection cage is full of nuts, the farmer must manually push two adjacent spring wires apart to create a discharge opening with a diameter larger than the nuts' diameter. This allows the nuts to be poured out smoothly for the next collection. Because some nuts have protruding points on their surfaces, such as the spikes on chestnut shells, the flat ends of almonds, and the ridges on walnuts, the nuts can easily scratch the farmer's hands during this unloading operation, posing a significant safety hazard. Furthermore, the existing collection cage and bracket are rotatably connected via a fixed axis, relying solely on the fixed axis for rotational support during rotation, resulting in poor stability and a need for further improvement.

[0005] Summary of the Invention

[0055] The first fixed pulley 611 and the second fixed pulley 612 are fixed on the bracket 2 , and one end of the pull rope 61 passes through the first fixed pulley 611 and the second fixed pulley 612 in sequence and is then fixedly connected to the positioning block 62 .

[0056] The torsion spring 614 has a spring coil mounted on the positioning shaft 63 , two torsion arms of the torsion spring 614 act on the first connecting rod 64 and the second connecting rod 65 , and both ends of the torsion spring 614 are fixed on the first rotating shaft 68 and the second rotating shaft 69 .

[0057] As shown in Figures 6-7, the transmission assembly also includes a pull member 613 that can slide axially along the handle 1. The other end of the pull rope 61 is fixedly connected to the pull member 613. When the pull member 613 slides upward along the handle 1, the pull member 613 drives the pull rope 61 to slide upward, and drives the first cover plate 51 and the second cover plate 52 to rotate and open under the action of the transmission assembly, so that the first cover plate 51 and the second cover plate 52 are moved away from the discharge port 4 to expose the discharge port 4. When the pull member 613 and the pull rope 61 are reset, the first cover plate 51 and the second cover plate 52 are opened. The cover plate 52 rotates and closes, thereby covering the discharge port 4; the pull piece 613 is tubular and is mounted on the handle 1. The pull piece 613 is provided with a trumpet-shaped grip portion, and the outer wall of the grip portion is provided with anti-slip ribs; accordingly, the handle 1 is provided with a first limiting piece 7 mounted on the handle 1, and the first limiting piece 7 is used to limit the pull piece 613 from sliding downward. The first limiting piece 7 is provided with a first through hole 71 along the axial direction of the handle 1, and the pull rope 61 is passed through the first through hole 71 and can slide in the first through hole 71.

[0058] The working principle in this embodiment is:

[0059] When not in use, the pull piece 613 is positioned on the handle 1 by the first limit piece 7, the first cover plate 51 and the second cover plate 52 are closed to cover the discharge port 4, and there is a gap between the two adjacent elastic wires 32 of the collection cage 3, so that nuts cannot enter or exit the collection cage 3.

[0060] When picking nuts, the fruit farmer holds the handle 1 and presses the collection cage 3 downward to deform the elastic wire 32, thereby increasing the gap between two adjacent elastic wires 32, so that the nuts scattered on the ground enter the collection cage 3 through the gap.

[0061] After the collecting cage 3 is filled with nuts, the pull piece 613 is pulled upward by hand, and the pull piece 613 drives the pull rope 61 to move upward. The pull rope 61 drives the positioning shaft 63 on the positioning block 62 to move upward along the guide hole 211 through the first fixed pulley 611 and the second fixed pulley 612. The upward movement of the positioning shaft 63 causes the first connecting rod 64 and the second connecting rod 65 to rotate relative to the positioning shaft 63, thereby driving the third connecting rod 66 and the fourth connecting rod 67 to rotate accordingly, so that the first cover plate 51 and the second cover plate 52 are opened, the discharge port 4 is exposed, and the nuts collected in the collecting cage 3 are moved out from the discharge port 4.

[0062] After dumping all the nuts in the collection cage 3, the fruit farmer releases the handle 1, and the torsion spring 614 resets the first connecting rod 64 and the second connecting rod 65, thereby driving the third connecting rod 66 and the fourth connecting rod 67 to rotate, so that the first cover plate 51 and the second cover plate 52 are closed, and at the same time drives the positioning shaft 63 to move downward along the guide hole 211, and the closed first cover plate 51 and the second cover plate 52 cover the discharge port 4; and the positioning shaft 63 moves the pull rope 61 downward through the positioning block 62, and the pull rope 61 resets the pull member 613 through the first fixed pulley 611 and the second fixed pulley 612.

[0063] As shown in Figure 8, this is a preferred second embodiment of the present invention. The handle 1, bracket 2, collection cage 3, discharge port 4, end cover 5 and drive assembly 6 of the nut collector have the same structure as those of the first embodiment, wherein the pull rope 61 in the drive assembly 6 is divided into an upper pull rope 61a and a lower pull rope 61b, one end of the upper pull rope 61a is fixedly connected to the pull member 613, the other end of the upper pull rope 61a is fixedly connected to one end of the lower pull rope 61b, and the other end of the lower pull rope 61b is fixedly connected to the positioning block 62; and a side ear 25 is provided on the bracket 2, and a second through hole is provided on the side ear 25 along the axial direction of the handle 1, and the lower pull rope 61b is passed through the second through hole and can slide in the second through hole; in addition, a second limiter 8 is provided at the upper end of the side ear 25, and the second limiter 8 is sleeved on the lower pull rope 61b, and the second limiter 8 is used to limit the lower pull rope 61b from sliding downward.

[0064] The above-mentioned method of rotating the end cover 5 to cover the discharge port 4 through the driving device 6 is only a preferred embodiment of the present invention and cannot be used to limit the scope of protection of the present invention. The end cover 5 can also be manually fastened to the discharge port 4 to close the discharge port 4, thereby enabling the collection cage 3 to pick up nuts; accordingly, the end cover 5 is manually moved away from the discharge port 4 to expose the discharge port 4, thereby allowing the nuts collected in the collection cage 3 to be moved out from the discharge port 4.
