Description

Technical Field

[0001] The utility model relates to the field of special tools for agricultural production, in particular to a handheld fruit thinning device. Background Art

[0002] Fruit thinning refers to the artificial removal of some fruits or flowers that are densely grown, weak, or in inappropriate positions during the cultivation of fruit trees, in order to ensure the quality and yield of the fruits. This measure helps to concentrate the nutrients of the fruit trees and supply the remaining fruits, thereby improving the quality and fruit setting rate of the fruits. For example, during the cultivation of greenhouse grapes, in addition to normal fertilization, watering, and pest management, flower and fruit thinning of grapevines is a high-quality cultivation technique to ensure the external and internal quality of grape fruits.

[0003] CN201839663U discloses a grape flower and fruit thinning device, which includes a U-shaped handle rod, rubber pads connected to both ends of the U-shaped handle rod, and tooth heads located on the rubber pads. The tooth heads on the two rubber pads are arranged inward and opposite to each other. The tooth heads have several small teeth. During the grape flower and fruit thinning operation, the small flowers (small berries) are thinned out by using the intersecting tooth heads to achieve the purpose of flower and fruit thinning.

[0004] CN215011828U discloses a thumb-pressing type grape fruit thinning device, which includes an upper cutting body and a lower cutting body. The upper cutting body includes a handle one and an arc-shaped bulging block one on the upper surface of the front half of the handle one. A semi-circular notch one is provided at the lower part of the front end of the bulging block one. The lower cutting body includes a handle two and an arc-shaped bulging block two on the lower surface of the front end of the handle two. A semi-circular notch two corresponding to the semi-circular notch one is provided at the lower part of the front end of the bulging block two. The cut grape grains leak out from a cylindrical through hole formed after the semi-circular notch one and the semi-circular notch two are aligned.

[0005] In the existing greenhouse grape fruit thinning technology, the fruit thinning device provided by CN201839663U uses multiple teeth on the claws to comb the fruit clusters to achieve the fruit thinning effect. Its disadvantage is that the fruit thinning effect is good at the positions with teeth on the upper and lower surfaces, and the fruit thinning effect is poor at the positions without teeth on the two side surfaces. In order to thin the fruits on the side surfaces, the fruit thinning device needs to be rotated to align the tooth positions with the fruit clusters on the side surfaces for fruit thinning. The disadvantage of the fruit thinning device provided by CN201839663U is that the blade cuts at the position where the small fruit stalk is close to the main spike axis. If it cannot be cut off in one stroke, the phenomenon of "clamping the fruit" will occur, and the small fruit, the fruit stalk, and the phloem tissue at the part where the fruit stalk is close to the main spike axis will be torn off together, causing damage to the phloem tissue, and the wound part is prone to infection by germs.

[0037] Embodiment

[0038] According to Figures 1-3 as shown, a hand-held fruit thinning device provided by the present utility model can be used for thinning flowers or fruit clusters and fruits, and select an appropriate fruit thinning period according to different plants. It includes an upper handle 1 and a lower handle 2. The rear ends of the upper handle 1 and the lower handle 2 are connected to a connecting member 3. The upper handle 1 and the lower handle 2 can be opened and closed. Fruit thinning plates 6 are installed at the front ends of the upper handle 1 and the lower handle 2, as Figure 4As shown in the figure, the fruit thinning plate 6 includes a plurality of strip-shaped fruit thinning strips 63. There are gaps 62 formed between the respective fruit thinning strips 63. The middle part of the fruit thinning plate 6 is a fruit thinning hole 61. When the upper handle 1 and the lower handle 2 are closed, the fruit thinning hole 61 located on the upper handle 1 and the fruit thinning hole 61 located on the lower handle 2 form a passage for the plant to pass through. The fruit thinning hole 61 can be semicircular, square or other shapes. The fruit thinning hole 61 provided in this embodiment is semicircular. When the upper handle 1 and the lower handle 2 are closed, the fruit thinning holes 61 on the upper and lower sides form a circular passage, and the plant passes through this circular passage. The circular passage can perform a full-round fruit thinning operation on the ear of corn at one time. The fruit thinning plate 6 is made of plastic or silica gel material. The fruit thinning strips 63 are elastic. During the process of pulling the fruit thinner, the fruit thinning strips 63 are deformed (such as Figure 5 shown as bulging outwards) to adapt to ears of different shapes. The elastic fruit thinning strips 63 will not scratch the branches of the plant, thus protecting the plant.

[0039] As Figures 1-2 shown, in order to facilitate the installation of the fruit thinning plate 6, an upper mounting seat 4 is installed at the front end of the upper handle 1, and a lower mounting seat 5 is installed at the front end of the lower handle 2. The fruit thinning plate 6 is installed on both the upper mounting seat 4 and the lower mounting seat 5.

[0040] In order to improve the fruit thinning efficiency, two fruit thinning plates 6 are installed on the upper mounting seat 4, and two fruit thinning plates 6 are installed on the lower mounting seat 5. A gap is formed between the two fruit thinning plates 6. Among them, the upper mounting seat 4 and the lower mounting seat 5 have the same structure. The upper mounting seat 4 includes an upper mounting frame 41, a front panel 42 and a rear panel 43. A fruit thinning plate 6 is installed between the upper mounting frame 41 and the front panel 42, and another fruit thinning plate 6 is installed between the upper mounting frame 41 and the rear panel 43. The lower mounting seat 5 includes a lower mounting frame 51, a front clamping plate 52 and a rear clamping plate 53. A fruit thinning plate 6 is installed between the lower mounting frame 51 and the front clamping plate 52, and another fruit thinning plate 6 is installed between the lower mounting frame 51 and the rear clamping plate 53.

[0041] During the process of pulling the fruit thinner, in order to prevent the upper mounting seat 4 and the lower mounting seat 5 from being misaligned, an upper positioning hole 411 and an upper pin 412 are provided on the upper mounting seat 4, and a lower positioning hole 511 and a lower pin 512 are provided on the lower mounting seat 5. When the upper handle 1 and the lower handle 2 are closed, the lower pin 512 is inserted into the upper positioning hole 411, and the upper pin 412 is inserted into the lower positioning hole 511. Through the cooperation of the positioning hole and the pin, the upper mounting seat 4 and the lower mounting seat 5 are combined together.

[0042] As Figure 3As shown in the figure, the rear ends of the upper handle 1 and the lower handle 2 are connected to the connecting member 3. Under the action of the connecting member 3, the upper handle 1 and the lower handle 2 can be opened and closed. The connecting member 3 is an elastic member, which can be constructed as an elastic sheet or an elastic rod, etc. The shape can be a V-shaped elastic sheet, a U-shaped elastic sheet, etc. In this embodiment, the connecting member 3 is a V-shaped elastic sheet. The two ends of the V-shaped elastic sheet are respectively connected to the upper handle 1 and the lower handle 2. For example, an installation groove 21 is provided on the lower handle 2, and one end of the V-shaped elastic sheet is inserted into the installation groove 21; when the operator forces the upper handle 1 and the lower handle 2 to close, the V-shaped elastic sheet is under pressure, and the elastic force of the V-shaped elastic sheet exerts a force on the upper handle 1 and the lower handle 2 to open; furthermore, when the operator does not apply force, the elastic force of the V-shaped elastic sheet (elastic member) causes the upper handle 1 and the lower handle 2 to open.

[0043] In order to facilitate the operator to hold the upper handle 1 and the lower handle 2, anti-slip strips are provided on the outsides of both the upper handle 1 and the lower handle 2.

[0044] Working principle

[0045] The upper handle 1 and the lower handle 2 of the fruit thinning device are in a natural open state without applying force. Place the flowers or fruit spikes on the branches to be thinned between the upper handle 1 and the lower handle 2; then the operator presses to close the upper handle 1 and the lower handle 2, and the branches of the plant pass through the circular channel formed by the fruit thinning holes 61 on the upper and lower sides; as Figure 5 shown in the figure, pull the fruit thinning device, and the fruit thinning strip 63 removes the excess flowers or small fruits. The fruit thinning strip 63 deforms (bends and protrudes outwards) to adapt to branches or fruit spikes of different shapes and avoid scratching the plants. Finally, the operator releases the upper handle 1 and the lower handle 2, and under the elastic force of the V-shaped elastic sheet, the upper handle 1 and the lower handle 2 open, completing the fruit thinning operation for this round.
