[0038] To make the objectives and technical solutions of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] A grape flower and bunch thinning machine includes a frame 1, a motor 2, a transmission gear set, a rotating frame 4, a rotating blade 8, an opening and closing mechanism, and a handle 12;

[0040] The frame 1 has a shaft structure, and the handle 12 is fixed at the axial end of the frame 1. The frame 1 and the fixed handle 12 form a support part.

[0041] A connecting frame with a waist hole extends radially along the handle 12. An opening and closing mechanism is provided on the connecting frame. The opening and closing mechanism cooperates with the waist hole on the connecting frame to realize opening and closing. Two rotating blades 8 are arranged inside the opening and closing mechanism. A bracket extends radially along the other axial end of the frame 1. A motor 2 is provided on the bracket. The motor 2 is used to drive the transmission gear set. The transmission gear set is connected to the rotating blades 8 through the rotating frame 4. A certain gap is provided between the two rotating blades 8.

[0042] like Figures 1 to 5 As shown: Motor 2 is a standard DC motor directly controlled by a switch, serving as the sole power source. The switch is manually operated, allowing Motor 2 to rotate in one direction. When the device needs to operate, the switch is pressed manually, and Motor 2 starts at full speed. The main gear 3, rotating frame 4, connecting gear 7, and gear support frame 6 in the device constitute a planetary gear system. The selected motor has a rated voltage of 12V and a rated speed of 100 r / min. After transmission through the motor gear 9 and the main gear 3, the rotation direction of the rotating frame 4 changes, while the speed remains at 100 r / min. This is calculated using the star gear calculation formula.

[0043]

[0044] It can be seen that the rotational speed of the connecting gear (7) is approximately 361.54 r / min.

[0045] The upper part of the frame 2 is held by hand, and the opening and closing of the gear support frame 6 is controlled by the linkage mechanism. That is, the gear support frame 6 is manually opened and closed by the crank-slider mechanism. The slide rod 11 is located in the limiting groove on the upper part of the frame 1. When the hand grips the handle 12 and the slide rod 11, the gear support frames 6 on both sides open under the action of the connecting rod 10, so that the grape spikes can be moved into or out of the device.

[0046] Each time the gear support frame 6 is opened, the stalk to be combed is placed between the two rotating blades 8, and adjusted as follows.Figure 3 The flower spike protection frame 5 is provided with a notch at the upper end of the interface, which facilitates clamping the grape spike axis to avoid rotation under the influence of the rotary cutter. After clamping the 3.5-5 cm spike tip part to be retained, the hand pushes the slide rod 11 forward, and the two side gear support frames 6 are closed under the drive of the connecting rod 10, and the device enters the pre-working state.

[0047] When cutting the flower spike, the motor is controlled to rotate in a certain direction, and the motor is stopped after the flower spike is completely thinned. In this structure, the connection of the rotary cutter 8 is shown as Figure 2 The rotary cutter 8 is fixedly connected with the cutter gear 7, and the cutter gear 7 is engaged with the gear support frame 6, so that the cutter rotates while rotating, thereby enhancing the cutting effect. At the same time, it can be seen that the combination of the two sides of the gear support frame 6 is respectively provided with buckles and clamping grooves, which facilitates the opening and closing of the gear support frame 6.

[0048] The total height of the grape thinning and thinning machine is about 420 mm, and the maximum width is about 230 mm, and the overall volume is small, which is convenient for handheld operation. The length of the rotary cutter 8 is 120 mm, and the outer diameter is 40 mm. The flower spike part to be removed is about 100 mm, so the device can completely remove the flower spike. The internal height of the flower spike protection frame 5 is about 60 mm, and the width is about 90 mm. The flower spike tip part to be retained is about 3.5-5 cm, which can be completely included in the flower spike protection frame 5. The size of the motor is shown in the figure. In order to reduce the weight of the whole machine, except for the core parts such as gears and rotary cutters, light plastic and the like can be selected as the raw material.

[0049] The gear support frame 6 is divided into left upper, left lower, right upper and right lower four parts, and the upper and lower parts on the same side are fixedly connected by a connecting rod. When the left and right gear support frames are closed, the inner sides of the upper and lower parts form a complete internal gear, which ensures that the cutter gear 7 can be engaged with the gear support frame 6 throughout the cycle, that is, the rotary cutter 8 rotates while rotating.

[0050] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
