Description

Technical Field

[0001] This application relates to the technical field of agricultural machinery, and in particular to a fruit thinning component, fruit thinning mechanism and fruit thinner. Background Technology

[0002] Fruit thinning is an important technique in agronomy. By removing some of the fruit and controlling the quantity to balance nutrient distribution, it aims to achieve stable, high-quality, and high-yield fruit production. Currently, most fruit thinning operations are done manually, using handheld tools such as scissors to remove some of the fruit. This method of fruit thinning is labor-intensive and inefficient.

[0003] To improve the efficiency of fruit thinning, some electric fruit thinners have appeared on the market. For example, patent CN118872503B discloses a "shaping and management machine for bunch-shaped fruits". The fruit bunches are clamped between a first box and a second box. Several shaping wheels are set on both the first box and the second box. The rolling of the shaping wheels thins the bunch-shaped fruits and removes some of the fruit bunches.

[0004] The aforementioned device drives the shaping wheels by rotating a swing arm via a swing motor. The swing arm connects all the shaping wheels on one side, thus achieving the rotation of several shaping wheels. This transmission structure, due to the swing arm requiring a certain amount of lateral space, results in a relatively large overall device size. Utility Model Content

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example 1

[0026] Figure 1 and Figure 2 The structure of a fruit thinner is shown, including a fruit thinning mechanism 1 and a connected handpiece 2. The fruit thinning mechanism 1 includes two identical and symmetrically arranged fruit thinning components 11. Each fruit thinning component 11 includes a roughly triangular box 111 with a mounting base 112 connected to one end face of the box 111. The mounting base 112 extends vertically outward from one end face of the box 111. The handheld component 2 includes two hinged first handles 21 and second handles 22. The ends of the first handles 21 and second handles 22 away from the hinged ends have a slot 23. The mounting base 112 can be engaged in the slot 23 to connect any fruit thinning component 11 to either the first handle 21 or the second handle 22. To improve the connection strength, after the mounting base 112 is engaged in the slot 23, a fastener is used to reinforce the connection. In this embodiment, the first handle 21 and the second handle 22 are connected to one of the fruit thinning components 11 respectively. When the first handle 21 rotates relative to the second handle 22, the two fruit thinning components 11 can move towards or away from each other.

[0027] See also Figure 3 and Figure 4 The fruit thinning component 11 includes a box body 111, a plurality of fruit thinning rollers 114, and a transmission assembly 115. The box body 111 includes a box base and a box cover 1113 connected thereto. In this embodiment, the box base is a split type, including a first base body 1111 and a second base body 1112 connected thereto. The plurality of fruit thinning rollers 114 are rotatably connected between the first base body 1111 and the second base body 1112, and the plurality of fruit thinning rollers 114 are placed on one side of the box body 111.

[0028] Both the first base 1111 and the second base 1112 have several spaced mounting slots 1114 on one side. Each mounting slot 1114 is equipped with a bearing 116. The fruit thinning component 11 includes a rotating shaft 1141 and several fruit thinning blocks 1142 on the outer peripheral wall of the rotating shaft 1141. The fruit thinning blocks 1142 are evenly distributed circumferentially, and each fruit thinning block 1142 extends along the axial direction of the rotating shaft 1141 in a roughly cuboid shape. Each fruit thinning block 1142 has at least one edge, which can be used to squeeze the fruit bunch to achieve the removal effect. The two ends of the rotating shaft 1141 are respectively connected to the bearings 116, thereby realizing the rotation of the fruit thinning component 11 relative to the box 111.

[0029] In this embodiment, a transmission groove 1115 is formed on one side of the second seat 1112. The transmission assembly 115 is installed in the transmission groove 1115 and connected to one end of the rotating shaft 1141. Specifically, the rotating shaft 1141 extends into the transmission groove 1115 from one end of the second seat 1112. The transmission assembly 115 includes a drive gear 1151, a speed regulating gear 1154, multiple transmission gears 1152, and multiple transition gears 1153. Each transmission gear 1152 is connected to the rotating shaft 1141 of a fruiting component 11. The drive gear 1151 is connected to a drive motor 113 located between the first seat 1111 and the second seat 1112. The drive shaft of the drive motor 113 also extends into the transmission groove 1115. The drive gear 1151 meshes with the speed regulating gear 1154. The drive gear 1151 meshes with two adjacent transmission gears 1152, and the remaining two adjacent transmission gears 1152 are connected by a transition gear 1153. When the drive motor 113 is working, it drives the drive gear 1151 to rotate. The rotation of the drive gear 1151 drives two of the transmission gears 1152 to rotate through the speed regulating gear 1154. One of the transmission gears 1152 transmits torque through the transition gear 1153, thereby realizing the rotation of all the fruit thinning rollers 114 relative to the housing 111. In this embodiment, the number of teeth of the speed regulating gear 1154 is greater than that of the drive gear 1151 and the transmission gears 1152, which can improve the rotation speed of the fruit thinning rollers 114.

[0030] In order to conceal the transmission assembly 115, the housing 111 is connected to one side of the second base 1112 to enclose the transmission groove 1115, thereby making the entire fruiting part 11 more aesthetically pleasing from an external perspective, and also protecting the transmission assembly 115 and extending its service life.

[0031] See also Figure 5 and Figure 6 The first handle 21 and the second handle 22 are also of a split structure. One end of the first handle 21 has a rotating shaft 213, and the second handle 22 has a mounting hole for the rotating shaft 213 to pass through. The first handle 21 and the second handle 22 are hinged through the rotating shaft 213.

[0032] The first handle 21 also has two limiting blocks 211 and a limiting seat 212 on one side. The two limiting blocks 211 are located near the slot 23 and have a gap between them to form a first guide opening 2111. The limiting seat 212 has a second guide opening 2121 and an adjusting groove 2122 that are spaced apart. An adjusting member 3 is rotatably connected in the adjusting groove 2122. The adjusting member 3 includes a cam body and a knob 31 connected to one end of the cam body. The knob 31 extends out from the adjusting groove 2122 and is located on the upper end face of the limiting seat 212.

[0033] The second handle 22 extends from one side of the first handle 21 and is provided with a first guide block 221 and a second guide block 222. The first guide block 221 can be inserted into the first guide opening 2111, and the second guide block 222 can be inserted into the second guide opening 2121. When the first handle 21 and the second handle 22 rotate around the rotation axis 213 and move closer to each other, the first guide block 221 and the second guide block 222 can be correspondingly inserted into the first guide opening 2111 and the second guide opening 2121 to limit the movement of the first handle 21 and the second handle 22 perpendicular to the sliding direction of either guide block, and at the same time limit the movement of the two fruit thinners 11. The connection between either guide block and the guide opening forms the guiding structure of the fruit thinner.

[0034] See also 7 and Figure 8 Several thinning rollers 114 in the two thinning components 11 are arranged opposite each other, and there is a gap between the two thinning components 11 to form a thinning area 12. The fruit bunches to be thinned can extend into the thinning area 12, and the opening size of the thinning area 12 can be adjusted by the adjusting component 3.

[0035] Specifically, the outer circumferential surface of the cam body consists of multiple sequentially connected cam segments with different curvatures. In this embodiment, five cam segments are provided: the first cam segment 32, the second cam segment 33, the third cam segment 34, the fourth cam segment 35, and the fifth cam segment 36. When the cam body is rotated by the knob 31, the outer surface of any cam segment extends out of the opening of the adjustment groove 2122, which can abut against one side of the second handle 22. Thus, when the first handle 21 and the second handle 22 rotate relative to each other, they are limited in one direction. At the same time, when the handpiece 2 is limited, the minimum opening of the fruit-retaining area 12 is also obtained. To facilitate the reliability of the minimum opening, the limiting seat 212 can be set with a gear at the knob 31 position to facilitate the operator's gear adjustment and observation.

[0036] When using this fruit thinner, first adjust the adjusting piece 3 to the corresponding position according to the type of fruit to be thinned. Then, align the first handle 21 and the second handle 22 with the fruit bunch to be thinned and operate them to rotate towards each other until they touch each other. Finally, drive the motor 113 to drive several fruit thinning rollers 114 to remove the fruit bunch. After completion, release the handpiece 2 and separate the first handle 21 and the second handle 22 through the elastic piece 4 in the second guide opening 2121. It should be noted that since the first handle 21 and the second handle 22 are hinged at one end, when the second guide block 222 is inserted into the second guide opening 2121, there is a gap between the upper and lower end faces of the second guide opening 2121 and the second guide block 222 to avoid jamming. Example 2

[0037] See Figure 9A fruit thinner, which differs from Embodiment 1 in that the speed regulating gear 1154 is removed from the transmission assembly 115, and the drive gear 1151 directly meshes with two of the transmission gears 1152. This connection method can change the installation position of the drive motor 113 in the housing 111, thereby further reducing the size of the equipment. Example 3

[0038] See Figure 10 A fruit thinner, which differs from Embodiment 1 in that the speed regulating gear 1154 is eliminated in the transmission assembly 115, and the drive gear 1151 directly meshes with one of the transmission gears 1152. This connection method can change the installation position of the drive motor 113 in the housing 111, thereby further reducing the size of the equipment.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
