[0002] The demand for small nuts is increasing, and the planting area of ​​these small nuts is also increasing. The most common way for workers to harvest nuts is to shake the branches themselves or use tools to shake them, especially for nuts like walnuts. A walnut shaking machine is connected to the other end of a rope tied to the trunk. However, this method is too rough, produces a lot of dust, and causes a lot of branches to fall, which requires subsequent cleaning.

[0003] Some workers use handheld harvesters to pick these small nuts. A search revealed, for example, a utility model with publication number CN209072930U, which discloses a handheld goji berry harvester. This harvester includes a main body with a front and rear opening assembly that can approach each other to capture and pick goji berries located between them. The harvester body has an internal cavity. However, this utility model is not convenient for adjusting its length during use. When workers need to harvest small nuts that are higher up, they need to use external tools such as ladders, wasting time and reducing work efficiency. Therefore, to solve these shortcomings, the inventor proposes a handheld nut harvester. Summary of the Invention

[0025] 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 protection scope of the present utility model.

[0026] Refer to the instruction manual appendix Figure 1-9 This embodiment of a handheld nut harvester includes a harvesting can 1 and a handle 2 located on one side of the outer surface of the harvesting can 1 for gripping. When the harvester is in its normal length, the operator can grip the handle 2 to operate the harvesting can 1.

[0027] A baffle 6 is threadedly connected to the bottom surface of the picking can 1. A sponge pad 601 is fixedly installed on the top surface of the baffle 6. The small nuts that are picked will fall into the picking can 1 and onto the sponge pad 601. Then, the baffle 6 is rotated to separate it from the picking can 1, and the small nuts inside the picking can 1 can be taken out.

[0028] To adjust the length of the harvester, a handle 3 is provided on the bottom surface of the baffle 6. The handle 3 has a hollow structure, and a threaded rod 302 is rotatably connected to the center of the inner bottom surface of the handle 3. A lifting rod 301 is slidably connected inside the handle 3, and the threaded rod 302 is threadedly connected to the lifting rod 301. When the threaded rod 302 rotates, the lifting rod 301 will rise and fall, thereby further driving the baffle 6 and the harvesting can 1 threadedly connected to the baffle 6 to move, thus realizing the adjustment of the length of the harvester itself and optimizing the user experience of the staff.

[0029] When the length of the handle 3 increases, the user can operate the entire harvester by holding the handle 3. Thus, the harvester's position remains unchanged, and the harvesting range can be adjusted by changing the length of the handle 3. The lifting height is also increased. When the harvester needs to harvest small nuts at higher positions, they only need to adjust the length of the handle 3.

[0030] To allow the threaded rod 302 to rotate, a rotating rod 305 is rotatably connected to the bottom of one side of the outer surface of the handle 3. A portion of the rotating rod 305 is located inside the handle 3, and the other portion is located outside the handle 3. A second bevel gear 304 is fixedly installed at the end of the rotating rod 305 inside the handle 3, and a handle 306 is fixedly installed at the end of the rotating rod 305 outside the handle 3. Rotating the handle 306 causes the rotating rod 305 to drive the second bevel gear 304 to rotate. A first bevel gear 303 is fixedly installed at the bottom of the outer surface of the threaded rod 302, and the first bevel gear 303 meshes with the second bevel gear 304. Because the first bevel gear 303 and the second bevel gear 304 are meshed, when the rotating rod 305 drives the second bevel gear 304 to rotate, it also drives the first bevel gear 303 to rotate, thus causing the threaded rod 302 to rotate.

[0031] In order to harvest small nuts, a connecting cover 4 is fixedly installed on the top surface of the harvesting can 1, and a harvesting opening 5 for harvesting nuts is opened on one side of the top surface of the connecting cover 4.

[0032] A drive groove 101 is provided on one side of the inner side of the harvesting opening 5. A blade 106 is slidably connected inside the drive groove 101. A first spring 102 is fixedly installed on one side of the drive groove 101 and is fixedly connected to the rear side of the blade 106. A traction rope 104 is fixedly installed on the rear side of the blade 106, and the first spring 102 is sleeved on the outer end of the traction rope 104. When the user pulls the traction rope 104, it will cause the blade 106 to move towards the side of the first spring 102, which will cause the blade 106 to squeeze the first spring 102. Then, the worker puts the small nut into the harvesting opening 5 and then releases the traction rope 104. The squeezed first spring 102 will drive the blade 106 to return to its original position, and the blade 106 can then cut the small nut. The cut small nut will fall into the harvesting can 1, thus completing the harvesting of the small nut. This harvesting action can be completed with one hand.

[0033] The outer surface of the picking can 1 and the outer top surface of the connecting cover 4 are rotatably connected to pulleys 103, and the traction rope 104 extends to one side outside the drive groove 101 and rolls in contact with the two pulleys 103.

[0034] To adjust the length of the traction rope 104, a pull rod 105 is provided on one side of the outer surface of the picking can 1. A rotating shaft 1051 is rotatably connected inside the pull rod 105. One end of the rotating shaft 1051 extends to the outside of the pull rod 105. A winding roller 1052 is fixedly installed on the side of the outer surface of the rotating shaft 1051 located inside the pull rod 105. The traction rope 104 passes through the through hole on the outer surface of the picking can 1 and is fixedly connected to the winding roller 1052. A rotating plate 1053 is fixedly installed on the end of the rotating shaft 1051 that extends to the outside of the pull rod 105. The user holds the handle 2 with their right hand and rotates the rotating plate 1053 with their thumb to drive the rotating shaft 1051 and the winding roller 1052 to rotate. The rotating winding roller 1052 can then wind up or release the traction rope 104, thereby adjusting the length of the traction rope 104 located outside the pull rod 105 so as to adjust the traction rope 104 according to the change in the length of the picker itself.

[0035] To limit the rotation plate 1053, a lifting groove 1054 is provided on the outer surface of the pull rod 105 on one side of the rotation plate 1053. A slide rod 1055 is fixedly installed inside the lifting groove 1054. A limit rod 1057 is slidably connected to the outer surface of the slide rod 1055. The limit rod 1057 can move up and down along the slide rod 1055. A second spring 1056 is fixedly installed on the inner top surface of the lifting groove 1054, and the second spring 1056 is sleeved on the outer end of the slide rod 1055. The second spring 1056 is fixedly connected to the limit rod 1057. When the limit rod 1057 rises, it will squeeze the second spring 1056. When the limit rod 1057 is released, the squeezed second spring 1056 will push the limit rod 1057 down to insert into the groove on the outer side of the rotation plate 1053, so as to limit the limit rod 1057 after rotation.

[0036] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
