Description
Technical Field
[0001] The utility model relates to the technical field of nut collecting tools, in particular to a nut collector. Background Art
[0002] After hazelnuts, chestnuts, walnuts, almonds and other nuts mature, they fall from the trees and scatter on the ground nearby, and need to be picked up in time for processing. Usually, the nuts scattered on the ground are collected by manual picking. Due to the large area and large number of nuts scattered, manual picking of nuts often requires a lot of physical strength of fruit farmers and is inefficient. For this reason, a nut collector, a handheld picking device, has appeared on the market, so that fruit farmers can pick up nuts without bending over. After searching, the nut picker in the prior art, such as the nut collector disclosed in Taiwan Patent TWI615091B "Nut Collector and Its Construction Method", mainly includes a handle, a bracket connected to the handle, and a collection cage rotatably connected to the lower end of the bracket. A plurality of metal wires are installed on the collection cage, and the metal wires can be compressed and deformed to increase the gap between two adjacent metal wires, forming a feed port with an aperture larger than the diameter of the nuts, so that the nuts scattered on the ground can enter the collection cage. During the entire picking process, the work efficiency is high and it is easy and convenient.
[0003] When the collection cage is full of nuts, the fruit farmer needs to manually push the two adjacent wires apart so that the collection cage has a discharge port with an aperture larger than the diameter of the nuts, so that the nuts can be smoothly poured out from the discharge port for the next collection. Since some nuts have protruding tips on the surface, such as the thorns on the chestnut shell, the flat ends of the almonds, and the ridges on the surface of the walnut, the nuts can easily scratch the farmer's hands during the above unloading operation, and the use of the nut collector has a great safety hazard; in addition, manually pushing the two adjacent wires apart to repeatedly pour the nuts can easily cause the elastic wire to deform and affect subsequent use, so further improvements are needed. Utility Model Content
[0004] In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a nut collector, which enables fruit farmers to unload the nut without having to manually push away the elastic metal wire of the collection cage, thereby reducing safety hazards during use and reducing deformation of the elastic metal wire.
[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a nut collector, comprising a collection cage and two wheel hubs arranged at both ends of the collection cage, the collection cage is formed by a plurality of elastic metal wires distributed in a circumference and connected to the two wheel hubs at both ends; the collection cage comprises: two cover cages arranged opposite to each other and capable of being assembled or separated from each other; each of the wheel hubs comprises a first half hub, a second half hub and a locking assembly; the first half hub and the second half hub are respectively arranged at one end of the two cover cages; a part of the locking assembly is arranged on the first half hub and the other part is arranged on the second half hub, and the locking assembly is used to lock or separate the first half hub and the second half hub.
[0006] After adopting the above technical solution, the utility model has the following beneficial effects: the two cages can be assembled into a complete collection cage through the first half hub, the second half hub and the locking assembly, so that the user can use it to pick up nuts. When it is necessary to take out the nuts in the collection cage, the user opens the first half hub and the second half hub through the locking assembly, so that the collection cage is separated into two halves to facilitate taking out the nuts in the collection cage. When the fruit farmer takes out the nuts, there is no need to pry apart the two adjacent metal wires, so as to avoid the nuts scratching the user and reduce the safety hazards in the use process.

[0020] This embodiment relates to a nut collector, such as Figure 1-6 As shown, it includes a collection cage 1 and two hubs arranged at both ends of the collection cage 1. The collection cage 1 is formed by a plurality of elastic metal wires 13 distributed in a circumference and connected to the two hubs at both ends. The collection cage 1 includes: two cages arranged opposite to each other and capable of being assembled or separated from each other, each hub including a first half hub 2, a second half hub 3 and a locking assembly 4. The first half hub 2 and the second half hub 3 are respectively arranged at one end of the two cages. A part of the locking assembly 4 is arranged on the first half hub 2, and the other part is arranged on the second half hub 3. The locking assembly 4 is used to lock or separate the first half hub 2 and the second half hub 3.
[0021] Specifically, Figure 2-3 As shown, the two cages are respectively a first cage 11 and a second cage 12. The first cage 11 is formed by a plurality of elastic metal wires 13 distributed in a semicircle and connected to the half hubs of the two hubs at both ends. The second cage 12 is formed by a plurality of elastic metal wires 13 distributed in a semicircle and connected to the other two half hubs of the two hubs at both ends.
[0022] Preferably, both cages can be semi-elliptical, hemispherical or semi-disc-shaped. The two cages can be combined into a complete collection cage 1, the first half hub 2 and the second half hub 3 are both semicircular but not limited to semicircular, preferably, the first half hub 2 and the second half hub 3 can be combined into a complete circular hub.
[0023] It should be noted that the two cages can be assembled into a complete collection cage 1 through the first half hub 2, the second half hub 3 and the locking assembly 4. When the user needs to take out the nuts in the collection cage 1, the user opens the first half hub 2 and the second half hub 3 through the locking assembly 4, so that the collection cage 1 is separated into two halves to facilitate taking out the nuts in the collection cage 1. When taking out the nuts, the fruit farmers do not need to pry apart the two adjacent metal wires, which prevents the nuts from scratching the fruit farmers and reduces the potential safety hazards during use.
[0024] Optionally, in order to realize that the locking assembly 4 fixes and splices the two half hubs or separates the two half hubs, thereby realizing locking, closing or opening the collection cage 1, the first half hub 2 and the second half hub 3 are symmetrically arranged so that the two half hubs can be spliced into a complete hub, such as Figure 4-6As shown, the first half hub 2 and the second half hub 3 are provided with a semicircular first slide groove 201 and a second slide groove 301 with two ends connected to each other, and the first half hub 2 is provided with a first guide groove 202 on the outer side, and the locking assembly 4 includes: a first locking block 41 and a first toggle member 42. The first locking block 41 is slidably assembled in the first slide groove 201. One end of the first toggle member 42 is connected to one end of the first locking block 41, and the other end is slidably assembled on the first guide groove 202. The first toggle member 42 can be used to drive the first locking block 41 to extend into the second slide groove 301 to lock the first half hub 2 and the second half hub 3, or to drive the first locking block 41 to retract the first slide groove 201 to separate the first half hub 2 and the second half hub 3. The first locking block 41 is in the shape of an arc arranged coaxially with the first slide groove 201. Preferably, the first locking block 41 is in the shape of a semicircular bar adapted to the first slide groove 201.
[0025] Further, such as Figure 4 As shown, in order to make the locking between the first half hub 2 and the second half hub 3 more stable, the locking assembly 4 also includes: a first limiting protrusion 43, two first limiting protrusions 43 are symmetrically arranged, and the first limiting protrusions 43 are arranged on an inner side wall near the end of the first guide groove 202. When the first locking block 41 extends into the second slide groove 301 to lock the first half hub 2 and the second half hub 3, or the first locking block 41 is completely retracted in the first slide groove 201, the first limiting protrusion 43 can limit the sliding of the first toggle member 42. Preferably, a first through hole 203 is arranged on the first half hub 2 on the outer side of the first guide groove 202 near the first limiting protrusion 43, and the first through hole 203 is used to provide a restoring force for the first limiting protrusion 43. In this embodiment, the distance between the first limiting protrusion 43 and the side of the first guide groove 202 opposite to the first limiting protrusion 43 is slightly smaller than the thickness of the first shifting member 42 , so that the first limiting protrusion 43 can limit the first shifting member 42 .
[0026] It should be noted that the two first limit protrusions 43 respectively form a first open stop and a first closed stop with the space between the two ends of the first guide groove 202. When it is necessary to merge the two cages to form a complete collecting cage 1, the first toggle member 42 is first pushed forward with force to disengage the first toggle member 42 from the first open stop, and then the first toggle member 42 is pushed along the first guide groove 202, so that the first toggle member 42 drives the first locking block 41 to slide along the first slide groove 201 to extend into the second slide groove 301 until the first toggle member 42 is stuck in the first closed stop, thereby achieving the first locking block 41 to be stably fixed in the second slide groove 301, thereby achieving locking between the first half hub 2 and the second half hub 3, thereby achieving the merging of the two cages to form a complete collecting cage 1. When it is necessary to take out the nuts in the collection cage 1 or transport and store them, first push the first toggle member 42 in the reverse direction with force to disengage the first toggle member 42 from the first closed stop position, and then push the first toggle member 42 along the first guide groove 202, so that the first toggle member 42 drives the first locking block 41 to slide along the second slide groove 301 and the first slide groove 201 until the first toggle member 42 is stuck in the first open stop position, so that the first locking block 41 is completely retracted in the first slide groove 201, so as to take out the nuts or facilitate the stacking of two cages, thereby reducing the space occupied by the collection cage 1 and facilitating the storage and transportation of the collection cage 1.
[0027] Optionally, in order to further stabilize the connection between the first half hub 2 and the second half hub 3, as Figure 5 , 6 As shown, the second half hub 3 is provided with a second guide groove 302 arranged opposite to the first guide groove 202 on the outside, and the second guide groove 302 is connected to the second slide groove 301, and the locking assembly 4 also includes: a second locking block 45 and a second toggle 46. The second locking block 45 is slidably mounted in the second slide groove 301, and the second locking block 45 is arranged opposite to the first locking block 41, and the second locking block 45 and the first locking block 41 can rotate synchronously. One end of the second toggle 46 is connected to one end of the second locking block 45, and the other end is slidably mounted on the second guide groove 302. The second toggle 46 can be used to drive the second locking block 45 to extend into the first slide groove 201 to lock the first half hub 2 and the second half hub 3, or to drive the second locking block 45 to retract the second slide groove 301 to separate the first half hub 2 and the second half hub 3. The second locking block 45 is in an arc shape coaxially arranged with the second slide groove 301. Preferably, the second locking block 45 is in the shape of a semicircular bar adapted to the second sliding groove 301 .
[0028] Furthermore, the locking assembly 4 further includes: a second limiting protrusion 47, two of which are symmetrically arranged, and the two second limiting protrusions 47 are respectively arranged on the inner side walls of the second guide groove 302 near the two ends, and the width of the second guide groove 302 where the second limiting protrusion 47 is arranged is slightly smaller than the outer circumference of the second toggle member 46. When the first half hub 2 and the second half hub 3 are in a locked state or an unlocked state, the second limiting protrusion 47 can limit the sliding of the second toggle member 46. Preferably, a second through hole 303 is arranged on the second half hub 3 at the outer side of the second guide groove 302 near the first limiting protrusion 43.
[0029] It should be noted that the two second limit protrusions 47 respectively form a second open stop and a second closed stop with the space between the two ends of the second guide groove 302. When it is necessary to merge the two cages to form a complete collection cage 1, the first toggle member 42 and the second toggle member 46 are first pushed forward with force to make the first toggle member 42 and the second toggle member 46 disengage from the first open stop and the second open stop respectively, and then the first toggle member 42 and / or the second toggle member 46 are pushed along the guide groove to make the first locking block 41 and the second locking block 45 slide synchronously in the slide groove, so that the first locking block 41 and the second locking block 45 extend into the first slide groove 201 and the second slide groove 301 respectively, until the first toggle member 42 and the second toggle member 46 are respectively stuck in the first closed stop and the second closed stop, thereby realizing the first locking block 41 is stably fixed in the second slide groove 301, thereby realizing the merging of the two cages to form a complete collection cage 1. When it is necessary to take out the nuts in the collection cage 1 or transport and store them, first push the first toggle member 42 and the second toggle member 46 in opposite directions with force, so that the first toggle member 42 and the second toggle member 46 are respectively disengaged from the first closed stop position, and then push the first toggle member 42 and the second toggle member 46 along the guide groove until the first toggle member 42 and the second toggle member 46 are respectively stuck in the first open stop position and the second open stop position, so that the first locking block 41 and the second locking block 45 are respectively completely retracted in the first slide groove 201 and the second slide groove 301.
[0030] Further, such as Figure 4-6 As shown, in order to further ensure that the locking of the first half hub 2 and the second half hub 3 is more stable, the first half hub 2 and the second half hub 3 are provided with positioning grooves 204 and positioning columns 31 that can be plugged into each other on opposite sides.
