[0026] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with embodiments.

[0027] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , a grape thinning device, comprising: a first pressing plate 10, a second pressing plate 20, a first shearing structure 30, a second shearing structure 40, a first limiting structure 50 and a second limiting structure 60; the first end of the first pressing plate 10 and the first end of the second pressing plate 20 are hinged ends, and the first end of the first pressing plate 10 and the first end of the second pressing plate 20 are hinged through a hinge shaft; the second end of the first pressing plate 10 and the second end of the second pressing plate 20 are free ends; the first shearing structure 30 is arranged on the inner side wall of the first pressing plate 10; the second shearing structure 40 is arranged on the inner side wall of the second pressing plate 20 and corresponds to the first shearing structure 30; the first limiting structure 50 is arranged on the inner side wall of the first pressing plate 10 and located between the first shearing structure 30 and the hinged end; the second limiting structure 60 is arranged on the inner side wall of the second pressing plate 20 and located between the second shearing structure 40 and the hinged end and corresponds to the first limiting structure 50;

[0028] Among them, when subjected to external force, the first pressing plate 10 and the second pressing plate 20 rotate axially relative to the hinge shaft, the first shearing structure 30 and the second shearing structure 40 are used to cooperate with each other to shear the flower buds or small fruits between the first shearing structure 30 and the second shearing structure 40; the first limiting structure 50 and the second limiting structure 60 are used to cooperate with each other to limit the depth of relative closing of the first pressing plate 10 and the second pressing plate 20 and limit the relative position of the first pressing plate 10 and the second pressing plate 20 in the width direction.

[0029] Specifically, in use, the free end is upward, the hinged end is downward, the cluster is placed between the first pressing plate 10 and the second pressing plate 20, the peduncle of the flower bud or the small fruit connected on the main stem of the cluster is embedded between the first shearing structure 30 and the second shearing structure 40, under the action of an external force, the first pressing plate 10 and the second pressing plate 20 gradually approach each other until the shearing force formed by the gradually interlaced first shearing structure 30 and the second shearing structure 40 shears the peduncle of the flower bud or the small fruit between the first shearing structure 30 and the second shearing structure 40 without damaging other flower buds or small fruits, thereby achieving the purpose of thinning the fruits and improving the quality of the grapes. In the process of the first pressing plate 10 and the second pressing plate 20 gradually approaching each other, the first limiting structure 50 and the second limiting structure 60 cooperate with each other to constrain the first pressing plate 10 and the second pressing plate 20 to stably rotate axially relative to each other, thereby ensuring that the relative position of the first pressing plate 10 and the second pressing plate 20 in the width direction does not change, so as to constrain the position of the first shearing structure 30 and the second shearing structure 40 when they coincide, ensure the smooth shearing, and improve the shearing efficiency. In the present application, the first shearing structure 30 and the second shearing structure 40 are the same in structure.

[0030] In a possible implementation, one end of the first shearing structure 30 and the second shearing structure 40 is provided with a groove;

[0031] Wherein, when the first pressing plate 10 and the second pressing plate 20 are relatively rotated under stress, the side surface of the first shearing structure 30 is in close contact with the side surface of the corresponding second shearing structure 40, and the groove on the first shearing structure 30 is interlaced with the groove of the corresponding second shearing structure 40, so as to shear the flower bud or the small fruit embedded in the groove.

[0032] Specifically, the first shearing structure 30 is a vertical plate fixed vertically on the first pressing plate 10, and the second shearing structure 40 is a vertical plate fixed vertically on the second pressing plate 20, and the top end of the vertical plate is provided with a groove. In the use state, the free end of the first pressing plate 10 and the second pressing plate 20 is upward, the hinged end is downward, the peduncle with a single flower bud or small fruit is clamped into the groove, and as the overlapping depth of the first pressing plate 10 and the second pressing plate 20 increases, the peduncle with a single flower bud or small fruit is finally broken under the shearing force of the two grooves moving in different directions. In the present application, the opening width of the groove is 2-4 mm, and the length of the vertical plate fixed vertically on the first pressing plate 10 and the vertical plate fixed vertically on the second pressing plate 20 is 10-14 mm.

[0033] In a possible implementation, the first limiting structure 50 includes a top column 51 extending in the direction perpendicular to the second pressing plate 20; the second limiting structure 60 includes a limiting groove 61 and a limiting boss 62; the limiting groove 61 extends in the direction perpendicular to the first pressing plate 10; and the limiting boss 62 is arranged inside the limiting groove 61.

[0034] When the first pressing plate 10 and the second pressing plate 20 are relatively rotated under force, the top post 51 gradually embeds in the limiting groove 61, and the limiting boss 62 is used to limit the displacement of the top post 51 to limit the rotating distance of the first pressing plate 10 and the second pressing plate 20.

[0035] Specifically, when the first pressing plate 10 and the second pressing plate 20 are relatively rotated under force, the top post 51 arranged on the first pressing plate 10 gradually engages in the limiting groove 61 arranged on the second pressing plate 20, and the relative positions of the first pressing plate 10 and the second pressing plate 20 during the relative rotation are constrained. Through the cooperation of the limiting groove 61 and the top post 51, and the limitation of the displacement of the top post 51 by the limiting boss 62, the relative rotating positions of the first pressing plate 10 and the second pressing plate 20 can be accurately controlled, and it is ensured that the first shearing structure 30 and the second shearing structure 40 can accurately stagger when reaching the predetermined positions, so as to realize the accurate shearing of the flower buds or small fruit stalks. In addition, the limiting boss 62 in the limiting groove 61 limits the distance of the top post 51, thereby limiting the rotating distance of the first pressing plate 10 and the second pressing plate 20, further limiting the staggering depth of the first shearing structure 30 and the second shearing structure 40. By accurately controlling the staggering depth and position of the first shearing structure 30 and the second shearing structure 40, it can be ensured that only the stalks of the target flower buds or small fruits are sheared, and unnecessary damage caused by the first shearing structure 30 and the second shearing structure 40 being staggered too deeply to contact other flower buds or small fruits is avoided, which helps to improve the overall quality and yield of grapes.

[0036] In a possible implementation, along the direction from the hinged end to the free end, the first shearing structure 30 is in two rows, and each row of the first shearing structure 30 includes a plurality of first shearing structures 30; along the direction from the hinged end to the free end, the second shearing structure 40 is in two rows, and each row of the second shearing structure 40 includes a plurality of second shearing structures 40.

[0037] Among them, along the direction from the hinged end to the free end, the distance between the two rows of first shearing structures 30 gradually increases, and the distance between the two rows of second shearing structures 40 gradually increases.

[0038] Specifically, since the shape of the grape cluster edge is large at the top and small at the bottom, the shape of the grape cluster is usually large at the top and small at the bottom, the distance between the two rows of first shearing structures 30 gradually increases, and the distance between the two rows of corresponding second shearing structures 40 gradually increases, which can perfectly match this shape feature and adaptively ensure that the shearing effect of the device at different parts is consistent. Regardless of the size of the diameter of the cluster, accurate and effective shearing can be obtained. In addition, each row of a plurality of first shearing structures 30 corresponds to each row including a plurality of second shearing structures 40, which can shearing a plurality of flower buds or small fruits at a time, significantly improving the shearing efficiency and reducing the time of repeated operation.

[0039] In a possible implementation, the grape thinning device further comprises a clamping protrusion 70; the clamping protrusion 70 is arranged between the two rows of second shearing structures 40, and a plurality of clamping protrusions 70 are arranged along the direction from the hinged end to the free end; the plurality of clamping protrusions 70 are used to limit the displacement of the main stem of the grape cluster.

[0040] Specifically, the top end of the clamping protrusion 70 is provided with a groove, the groove at the top end of the clamping protrusion 70 is used to radially clamp the main stem of the grape cluster, and the displacement of the main stem of the grape cluster in the shearing process can be effectively limited. Since the grape cluster usually has a certain weight and shape, if it is not properly fixed, it may shake or move during shearing, affecting the shearing accuracy, and even mistakenly injuring other flower buds or small fruits. The arrangement of the clamping protrusion 70 improves the stability of the grape cluster during shearing. In this application, at least three clamping protrusions 70 are arranged along the direction from the hinged end to the free end, so as to fix the head, middle and tail of the main stem of the grape cluster.

[0041] In a possible implementation, the grape thinning device further comprises:

[0042] A compression spring 80 is arranged at the position close to the hinged shaft of the first pressing plate 10 and the second pressing plate 20.

[0043] Specifically, the two ends of the compression spring 80 are fixed on the inner walls of the first pressing plate 10 and the second pressing plate 20 respectively. The compression spring 80 provides the elastic force required for the reset of the first pressing plate 10 and the second pressing plate 20. After the shearing operation is completed, the elastic force of the spring will push the first pressing plate 10 and the second pressing plate 20 back to the initial position, so as to prepare for the next shearing operation, so that the grape thinning device has continuity and stability. Moreover, due to the existence of the compression spring 80, the user does not need to manually reset the pressing plate when operating the grape thinning device, which simplifies the operation process and improves the operation efficiency, so that the user can more easily complete the thinning task.

[0044] In a possible implementation, the outer side surface of the first pressing plate 10 and the second pressing plate 20 is provided with an anti-skid pattern.

[0045] Specifically, as shown in Figure 5 the back surface of the first pressing plate 10 and the second pressing plate 20 is provided with an anti-skid pattern, and the anti-skid pattern in this application is a plurality of small convex dots. The anti-skid pattern can increase the friction between the user's hand and the first pressing plate 10 and the second pressing plate 20, so as to prevent the pressing plate from slipping or losing control due to the wet and slippery hand during use. The stable holding of the grape thinning device by the user helps to more accurately control the shearing position and force, and improves the shearing accuracy.

[0046] In a possible implementation, the cross section of the first pressing plate 10 and the second pressing plate 20 is an outwardly convex arc.

[0047] Specifically, the cross section of the first pressing plate 10 and the second pressing plate 20 is outwardly convex arc, so that the space between the first pressing plate 10 and the second pressing plate 20 is more inclined to be circular, more suitable for the shape of the cluster, and also avoid extrusion to the cluster. In addition, the first pressing plate 10 and the second pressing plate 20 are outwardly convex, so that the palm of the user can better fit the first pressing plate 10 and the second pressing plate 20, and increase the stability of holding.

[0048] Further illustrated by the following embodiments:

[0049] The grape thinning device in the application is used, the first pressing plate 10 and the second pressing plate 20 are held by hand, the free end of the first pressing plate 10 and the second pressing plate 20 is on the top, the hinged end of the first pressing plate 10 and the second pressing plate 20 is on the bottom, then the fruit cluster to be treated is placed between the first pressing plate 10 and the second pressing plate 20, then the main stem of the fruit cluster is clamped into the clamping protrusion 70, at this time the handle of the single flower bud or small fruit connected on the main stem of the fruit cluster is embedded into the groove of the first shearing structure 30 and the second shearing structure 40. The hand applies force to make the first pressing plate 10 and the second pressing plate 20 relatively rotate around the hinged shaft until the first shearing structure 30 on the first pressing plate 10 and the second shearing structure 40 on the second pressing plate 20 gradually approach, until staggered, in the process of staggering, the handle of the single flower bud or small fruit clamped in the groove of the first shearing structure 30 and the second shearing structure 40 is cut off, realizing the purpose of thinning.

[0050] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
