Abstract
Description
Technical Field
[0001] The utility model belongs to the field of fruit thinning devices, in particular to a fruit thinning device for apples during the fruit setting period. Background Art
[0002] Apples have umbel inflorescences and fruit in clusters when they set. Apple cultivation requires fruit thinning during the fruit-setting period to improve quality and yield. Traditional fruit thinning involves manually pinching or using hand-held thinning shears to cut off weak fruits while retaining strong ones. Thinning with shears involves inserting the blade of the thinning shears between weak and strong fruits and firmly pinching the shears handles to sever the stalks of the side fruits. Frequent pinching of the shears handles can easily cause soreness and weakness in the worker's hands, especially fingers, affecting work efficiency. Furthermore, strong fruits are unprotected during the thinning process, and the blade can easily collide with them if not handled with caution, damaging them. Manual pinching uses fingers to separate strong fruits from weak ones, then pinches off the stalks of weak fruits and pulls them upwards. This method avoids scratching the strong ones, but the force is difficult to control and can easily pull down entire clusters of apples, causing losses. Utility Model Content
[0003] In order to solve the problems existing in the above-mentioned prior art, the utility model provides an apple fruit thinning device during the fruit setting period, which can quickly prune weak fruits, saving time and labor, and at the same time protect strong fruits from bumping and not pulling off during the pruning process.
[0004] The specific technical solution adopted in this utility model is:
[0005] A fruit thinner for apples during the fruit setting period comprises a handle and a cutting device arranged at the end of the handle. The key point is that the cutting device comprises a cutting knife and a fruit stalk gathering frame fixedly connected to the handle, the frame body of the fruit stalk gathering frame is provided with an opening and has a hook-shaped structure with the help of the opening, the handle is provided with a driving motor, the cutting knife is hinged to the fruit stalk gathering frame with the help of a driving shaft fixed thereto, the driving shaft is in transmission connection with the driving end of the driving motor, the cutting knife has the freedom to pass through the inner side of the fruit stalk gathering frame with the help of the driving motor, and the handle is also provided with a switch for the driving motor.
[0006] The fruit stalk gathering frame is an arc-shaped structure.
[0007] The axis of the driving shaft is perpendicular to the axis of the fruit stalk gathering frame. A cutting edge is provided on the inner wall of the fruit stalk gathering frame. The cutting knife rotates along the axis of the driving shaft and cooperates with the cutting edge to cut the fruit stalk.
[0008] The cutting knife is a fan-shaped blade, and the blade of the cutting knife is arranged along the arc surface of the cutting knife.
[0009] A protective rubber sleeve is provided on the outer side of the fruit stalk gathering frame, and the side edges of the protective rubber sleeve are all rounded edges.
[0010] The beneficial effects of the utility model are:
[0011] The fruit stalk gathering frame used in the utility model has an opening on one side, and weak fruits are hooked into the fruit stalk gathering frame through the opening to be separated from strong fruits. The cutting knife rotates in the fruit stalk gathering frame to cut the stalks of weak fruits, thereby preventing the hard cutting knife from colliding with the strong fruits.
[0012] The fruit stalk gathering frame can be used to gather multiple weak fruit stalks in the inflorescence cluster and cut them uniformly, reducing the frequency of triggering the switch, reducing finger movements, and relieving finger fatigue;
[0013] The cutting knife rotates to cut off the stems of weak fruits with uniform force to avoid pulling the entire cluster of apples from the branch and causing loss of strong fruits. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0019] Specific embodiments, such as Figure 1-3As shown, a fruit thinner for apples during the fruit setting period includes a handle 1 and a cutting device arranged at the end of the handle 1. The key point is that the cutting device includes a cutting knife 2 and a fruit stalk gathering frame 3 fixedly connected to the handle 1, the frame body of the fruit stalk gathering frame 3 is provided with an opening and has a hook-shaped structure with the help of the opening, the handle 1 is provided with a driving motor, the cutting knife 2 is hinged to the fruit stalk gathering frame 3 with the help of a driving shaft 4 fixedly connected thereto, the driving shaft 4 is transmission-connected to the driving end of the driving motor, the cutting knife 2 has the freedom to pass through the inner side of the fruit stalk gathering frame 3 with the help of the driving motor, and the handle 1 is also provided with a switch 5 of the driving motor. During operation, the staff holds the handle 1 and moves the handle 1 so that the frame of the fruit stalk gathering frame 3 is directed towards the strong fruit. The fruit stalk gathering frame 3 uses its opening to hook and gather the single or multiple weak fruit stalks around the strong fruit, and then closes the switch 5 to make the driving motor work. The driving motor drives the driving shaft 4 to rotate, and the cutting knife 2 rotates under the drive of the driving motor to cut off the stalks of the weak fruits in the fruit stalk gathering frame 3. The cutting device simulates the method of manual pinching to separate the weak fruit from the strong fruit and cuts off the stalks of the weak fruit and throws them up, which can prevent the cutting knife 2 from accidentally colliding with the strong fruit, and does not require manual pinching. The weak fruit stalks can be easily cut off, and the cutting force is uniform and the whole cluster of fruits will not be pulled down. It is suitable for cutting the thinner fruit stalks of apples; the switch 5 is a push button switch. When holding the handle 1, pressing the switch 5 with the thumb can start or stop the driving motor to cut the fruit stalks. There is no need to pinch them hard, and multiple weak fruit stalks can be cut at the same time, which helps to improve the work efficiency of fruit thinning.
[0020] Furthermore, the frame body of the fruit stalk gathering frame 3 is an arc-shaped structure, and there is no flat surface on the fruit stalk gathering frame 3 adjacent to the strong fruit, which greatly reduces the occurrence of collisions with the strong fruit when the handheld fruit thinner is working, and the outer side of the fruit stalk gathering frame 3 has no sharp corners, which will not cause scratches to the strong fruit.
[0021] Furthermore, a protective rubber sleeve 7 is provided on the outside of the fruit stalk gathering frame 3. The side edges of the protective rubber sleeve 7 are all rounded edges. Even if it accidentally comes into contact with the strong fruit, due to the setting of the protective rubber sleeve 7, the fruit stalk gathering frame 3 is not likely to cause damage to the skin of the strong fruit.
[0022] Furthermore, in this embodiment, the axis of the drive shaft 4 is perpendicular to the axis of the fruit stem collection frame 3. A cutting edge 6 is provided on the inner wall of the fruit stem collection frame 3, offset inward. The cutting edge 6 is arranged in an arc shape along the inner wall of the fruit stem collection frame 3. The cutting knife 2 is a fan-shaped blade, and the cutting edge 8 of the cutting knife 2 is arranged on its arc surface. In the initial state, the cutting edge 8 of the cutting knife 2 is directed outward from the opening of the fruit stem collection frame 3, facilitating the fruit stem collection frame 3 to remove weak fruit stems. When the switch 5 is closed, the cutting knife 2 passes from bottom to top along the axis of the drive shaft 4 through the cutting edge 6 in the fruit stem collection frame 3. The cutting edge 8 cooperates with the cutting edge 6 to cut the fruit stem. The cutting knife 2 continues to rotate, and the weak fruit stems are ejected upward. The cutting knife 2 has a circular arc structure, which can fully cooperate with the cutting edge 6 within the fruit stem collection frame 3, expanding the cutting range and ensuring that all fruit stems within the fruit stem collection frame 3 are cut.
