Description

Technical Field

[0001] The utility model relates to the technical field of fruit picking machinery, and particularly relates to a fruit picker. Background Art

[0002] For traditional fruit picking, especially for concentrated picking of nuts such as pinecones, chestnuts, and walnuts on tall trees, it is basically all done by manually climbing a pole and hitting, which requires high physical strength, low efficiency, and high danger.

[0003] Therefore, in related technologies, there have emerged some fruit pickers using mechanical picking methods, which mainly utilize the vibration principle to achieve picking. Specifically, a fruit picker capable of generating vibration is fixed to the trunk of a fruit tree by fixing parts such as straps, and then the fruit picker is turned on. By vibrating the trunk through the fruit picker, the fruits on the trunk can fall off under vibration to achieve picking.

[0004] However, this kind of fruit picker still has deficiencies in actual use. For example, when fixing the fruit picker to the trunk using a strap, one person needs to continuously hold the fruit picker, and another person operates the strap to tie it to the trunk, which is rather laborious. Moreover, the fruit picker is only fixed to the trunk by a strap. Once the strap breaks or falls off, the fruit picker will directly fall down, which has certain safety hazards and thus still needs to be improved. Summary of the Utility Model

[0005] In order to solve at least one technical problem mentioned in the background art, the purpose of the utility model is to provide a fruit picker.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0008] The advantages of adopting this solution are as follows:

[0009] In this solution, by setting a safety belt independent of the machine body and a hanging member on the safety belt, when tying and fixing the machine body to the trunk of a tree, the safety belt can be first tied and fixed to the trunk of a tree, and then the machine body is lifted up so that the gas is hung on the hanging member of the safety belt. At this time, the machine body is lifted by the safety belt. In this way, it is no longer necessary for someone to hold the machine body later. The user can directly use the fixing part to tie and fix the machine body to the trunk of a tree. It can be seen that with such a design, a single person can complete the fixing of the machine body, and the operation is relatively simple.

[0010] Moreover, with such a design, even if the fixing member breaks or falls off subsequently, the machine body will not fall directly, but will be suspended by the safety belt, thus preventing potential safety hazards caused by the falling of the machine body.

[0013] As an optional embodiment of the present utility model, the suspension member further includes a sling, the sling is provided on the safety belt, and the hook is provided on the sling.

[0014] As an optional embodiment of the present utility model, the vibration mechanism includes a motor, a driving gear and two eccentric gears; the motor is fixed on the machine body; the driving gear and the two eccentric gears are both rotatably connected to the machine body; wherein the two eccentric gears are meshed with each other, and the driving gear is meshed with one of the eccentric gears and driven to rotate by the motor.

[0015] As an optional embodiment of the present utility model, the two eccentric gears are arranged vertically in sequence; in the working state, the linear velocity direction at the meshing position of the two eccentric gears faces the tree trunk.

[0016] As an optional embodiment of the present utility model, the driving gear is meshed with the upper eccentric gear and rotates counterclockwise. In the axial projection along the driving gear, the driving gear is located at the lower left of the upper eccentric gear.

[0017] As an optional embodiment of the present utility model, the machine body includes a housing, and the driving gear and the two eccentric gears are both encapsulated in the housing.

[0018] As an optional embodiment of the present utility model, holes are formed in the housing.

[0019] As an optional embodiment of the present utility model, one or more support feet are provided on the side of the machine body facing the tree trunk, and the surface of the support foot facing the tree trunk is a concave arc surface structure.

[0028] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the attached drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work all fall within the protection scope of the present utility model.

[0029] In the following description, terms indicating orientation or positional relationship such as "inner", "outer", "upper", "lower", "left", "right", etc. are only for the convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0030] Please refer to Figures 1-4 As shown, this embodiment provides a fruit picker, which can be applied to some fruit trees that can be picked by vibration, such as the centralized picking of nuts such as tall pine cones, chestnuts, and walnuts.

[0031] The fruit picker provided in this embodiment includes a machine body 1 and a fixing member (not shown in the figure), and the machine body 1 includes a machine shell 11.

[0032] A vibration mechanism for causing the machine body 1 to vibrate is provided on the machine body 1, and the fixing member is used to bind and fix the machine body 1 to the tree trunk.

[0033] The fixing member here can be a component such as a strap (not shown in the figure). The body 1 is tied and fixed to the trunk of the fruit tree to be picked by relying on the strap. Subsequently, the vibration mechanism drives the body 1 to vibrate, and then the body 1 drives the fruit tree to vibrate, so as to vibrate the fruits on the fruit tree and drop them, realizing picking.

[0034] The fruit picker provided in this embodiment further includes a safety belt 2. The safety belt 2 is independent of the body 1 and is used to be tied and fixed to the trunk. Here, being independent of can be understood as that the safety belt 2 and the body 1 are two separable components, rather than two inseparable components connected together.

[0035] As Figure 1 shown, a hanging member is provided on the safety belt 2, and the body 1 can be detachably hung on the safety belt 2 through the hanging member.

[0036] During use, first tie and fix the safety belt 2 to the trunk; then lift the body 1 and hang the body 1 on the hanging member on the safety belt 2. In this way, the body 1 can be lifted by relying on the safety belt 2, so that there is no need to hold the body 1 manually anymore. Then, use the fixing member to tie and fix the lifted body 1 to the trunk. Finally, turn on the vibration mechanism to drive the body 1 to vibrate so as to vibrate the fruits on the fruit tree and drop them, realizing picking.

[0037] With such a design, when using the fixing member to tie and fix the body 1, since the body 1 is in a state of being lifted by the safety belt 2, there is no need to hold the body 1 manually anymore. The user can directly use the fixing member to tie and fix the body 1 to the trunk. It can be seen that with such a design, a single person can complete the fixing of the body 1, and the operation is relatively simple.

[0038] Moreover, even if the fixing member breaks or falls off subsequently, the body 1 will not directly fall down, but will be hung by the safety belt 2, thus preventing the problem of potential safety hazards caused by the falling of the body 1. In short, the safety belt 2 at this time is equivalent to a safety protection component for preventing the accidental falling of the body 1.

[0039] In some embodiments, as Figure 3 shown, the safety belt 2 is in a flat strip shape. In order to quickly lock and tie the safety belt to the trunk, in this embodiment, a buckle 21 is provided on the safety belt 2, and the safety belt 2 can be connected through the buckle 21 so that the safety belt 2 is tied and fixed to the trunk; the buckle 21 here can refer to some existing belt buckles (or trouser belt buckles), and no more details will be elaborated here.

[0040] The buckle 21 is fixed to one end of the safety belt 2. When in use, the safety belt 2 is wound around the trunk along the circumferential direction of the trunk. Then, the end of the safety belt 2 far from the buckle 21 is passed through the buckle 21 to an appropriate tightness position, and the safety belt 2 is locked by the buckle 21, so as to fix the safety belt 2 and bind and fix the safety belt 2 on the trunk.

[0041] Of course, in some other alternative embodiments, the buckle 21 may not be provided. Instead, after the safety belt 2 is wound around the trunk, the two ends of the safety belt 2 are directly knotted and fixed, so that the safety belt 2 can also be bound and fixed on the trunk.

[0042] In some embodiments, as Figure 1 shown, the suspension member includes a hook 23, and a hanging ring 12 for the hook 23 to hook is provided on the body 1. Specifically: the suspension member further includes a sling 22, the sling 22 is provided on the safety belt 2, and the hook 23 is provided on the sling 22; in the unfolded state, as Figure 3 shown, the sling 22 and the safety belt 2 are in a T-shaped structure. The hanging ring 12 is fixed to the top of the body 1.

[0043] When in use, first bind the safety belt 2 to the trunk, and then lift the body 1 so that the hanging ring 23 on the body 1 hooks to the hook 23 of the sling 22, so that the safety belt 2 can lift the body 1 with the help of the sling 22.

[0044] In some embodiments, the sling 22 and the safety belt 2 are detachably connected to each other. Specifically, the sling 22 is in a closed-loop structure, and the safety belt 2 passes through the loop of the sling 22, and the sling 22 is lifted by relying on the safety belt 2; the hook 23 is fixed on the sling 22.

[0045] Of course, in some other alternative embodiments, the sling 22 can also be directly fixed on the safety belt 2, such as by sewing or the like.

[0046] In order to enable the body 1 to better adapt to the curvature of the trunk to contact the trunk, in this embodiment, as Figure 1 and Figure 2 shown, one or more support feet 15 are provided on the side of the body 1 facing the trunk. For example, in this embodiment, two support feet 15 are shown, and the two support feet 15 are arranged in sequence along the vertical direction. The vertical direction in this embodiment can also be understood as the suspension direction of the body 1. The surface of the support foot 15 facing the trunk is a concave arc surface structure.

[0047] In addition, a flexible pad body 16, such as a rubber pad, is fixed on the arc surface structure of the support foot 15, and the pad body 16 fits the arc surface of the support foot. The purpose of using the flexible pad body 16 is to prevent the rigid support foot 15 from directly contacting the tree trunk. If the rigid support foot 15 directly contacts the tree trunk, when the machine body 1 vibrates during operation, the support foot 15 is likely to abrade the bark of the tree trunk. By setting the pad body 16 to contact the tree trunk, it is a soft contact between the bark and the pad body 16 at this time, so it is not easy to cause damage to the bark.

[0048] In this embodiment, the fixing member for binding and fixing the machine body 1 is preferably a flexible strap (not shown in the figure).

[0049] Specifically, as Figure 1 shown, the fixing member further includes a tightener 41 for tightening the strap and a winding shaft 42 for fixing the strap. The tightener 41 and the winding shaft 42 are respectively arranged on both sides of the machine body 1. Specifically, the tightener 41 and the winding shaft 42 are fixed on both sides of the machine shell 11. One end of the strap is fixed on the winding shaft 42.

[0050] The tightener 41 is mainly used to tighten the strap, and its structure and principle are described in detail in the prior art, so no more details will be elaborated here.

[0051] When using the strap to fix the machine body 1, first, support the two support feet 15 of the machine body 1 on the tree trunk. Then, lead the strap out from the winding shaft 42, bypass the tree trunk, and then pass through the tightener. After reaching the appropriate tightness, use the tightener 41 to tighten the strap, thus completing the binding and fixing of the machine body 1.

[0052] Of course, in some other optional embodiments, the tightener 41 may not be provided. After directly using the strap to bypass the tree trunk machine body 1, the machine body 1 can be bound and fixed to the tree trunk by tying a knot in the strap.

[0053] In some embodiments, as shown in combination with Figure 2 and Figure 4 shown, the vibration mechanism includes a motor 31, a driving gear 32, and two eccentric gears (33, 34). The motor 31 is fixed on the machine body 1. For example, the motor 31 is fixed on the side of the machine body 1. Among them, the motor 31 is preferably a gasoline engine, and of course, it can also be a diesel engine or an electric motor, etc., and no specific limitation is made here.

[0054] The driving gear 32 and the two eccentric gears are all rotatably connected to the machine body 1. Specifically, the driving gear 32 and the two eccentric gears are all encapsulated in the machine shell 11 and are shielded by the machine shell 11 to improve safety.

[0055] Among them, the two eccentric gears mesh with each other. The driving gear 32 meshes with one of the eccentric gears, and the driving gear 32 is driven to rotate by the motor 31. The rotation axes of the three gears are parallel to each other.

[0056] It should be noted that in this embodiment, the eccentric gear refers to a gear whose center of gravity deviates from the center of the gear circle. It can be manufactured by subtractive manufacturing methods. For example, a part of the side surface of the gear is cut and thinned so that the gear becomes an eccentric gear.

[0057] Of course, in some other embodiments, the eccentric gear can also be manufactured by additive manufacturing methods. For example, a counterweight is fixed on the side surface of the gear so that the center of gravity of the gear deviates from the center of the circle, forming an eccentric gear.

[0058] The two eccentric gears are arranged vertically in sequence. For the convenience of description, in this embodiment, the upper eccentric gear is denoted as the upper eccentric gear 33, and the corresponding lower eccentric gear is denoted as the lower eccentric gear 34.

[0059] In the working state, that is, when the machine body 1 is fixed to the tree trunk and the motor 31 is working, as Figure 4 shown, the linear velocity direction V at the meshing position of the two eccentric gears faces the tree trunk. The significance of such a design is that the linear velocity direction at the meshing position of the two eccentric gears faces the tree trunk, so that the centrifugal force direction at the meshing position of the two eccentric gears is towards the tree trunk (it can also be understood as towards the support foot 15), so that it impacts towards the tree trunk instead of away from the tree trunk, which is beneficial to the stability of the fixation of the machine body 1.

[0060] For example, in this embodiment, the driving gear 32 is driven by the motor 31 to rotate counterclockwise (in the direction shown by RO in Figure 4 ), the driving gear 32 meshes with the upper eccentric gear 33, so that the upper eccentric gear 33 rotates clockwise (in the direction shown by R1 in Figure 4 ), and the corresponding lower eccentric gear 34 rotates counterclockwise (in the direction shown by R2 in Figure 4 ), so that the linear velocity direction V at the meshing position of the upper eccentric gear 33 and the lower eccentric gear 34 horizontally faces the tree trunk.

[0061] In addition, in the axial projection along the driving gear 32, that is, Figure 4 from the perspective shown, the driving gear 32 is located at the lower left of the upper eccentric gear 33 and does not contact the lower eccentric gear 34. The significance of such a design is that the installation position of the driving gear 32 can be at the lower part of the middle of the machine body 1, so that the installation position of the motor 31 on the machine body 1 also tends to be at the lower part of the middle, so that the center of gravity of the entire fruit picker can be lowered, which is beneficial to reducing the center of gravity of the entire fruit picker.

[0062] In addition, as Figure 1and Figure 2 As shown, a hole 13 is provided on the casing 11. The purpose of providing the hole 13 is, firstly, to reduce the material of the casing 11 to reduce the weight of the casing 11, thereby reducing the weight of the entire fruit picker. Secondly, these holes 13 can also be used as observation holes for observing the internal situation of the casing 11.

[0063] Specifically, as Figure 1 shown, holes 13 can be provided on the side surface of the casing 11 close to the support feet 15, and / or holes can be provided on the side surface of the casing 11 opposite to the motor 31 (due to perspective reasons, not shown in the figure); among them, the holes provided on the side surface of the casing 11 opposite to the motor 31 are preferably covered with plastic sheets 14 to prevent external stones from entering the casing 11 through these holes and affecting the operation of the machine.

[0064] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
