Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable planting equipment, specifically to a grape flower thinner. Background Technology

[0002] Thinning of flower clusters refers to retaining a certain number of flower clusters on a fruiting branch. This requires effective management of the number of fruiting branches during the grape's bud break period. Too many fruiting branches overburden the vine, making it difficult for the root system to meet the nutrient needs of all the fruit clusters, and also severely impacting ventilation and light penetration. Current thinning methods often use scissors, but these leave large wounds. Therefore, some technologies use roller-shaped thinners, which improve efficiency and reduce the size of the cut. However, the cuts still exist, and if not treated promptly, they hinder subsequent fruit thinning operations. Therefore, without solving the aforementioned problems, a grape flower thinning device is proposed in a targeted manner. Utility Model Content

[0003] This invention addresses the problems mentioned above by designing a grape flower thinner. This device can remove excess flower clusters from grape branches, preventing the fruit from becoming too small due to insufficient nutrition caused by excessive fruit production. Furthermore, it sprays a fungicide after flower thinning to prevent infection of the branch cuts, which would be detrimental to the fruit thinning operation.

[0004] To achieve the above objectives, this utility model provides a grape thinning device, comprising: a holding part, a carrier box, a thinning device, and a spraying device. The holding part has a scissor-shaped structure. There are two carrier boxes and two thinning devices. The two carrier boxes are independently disposed on the two ends of the upper part of the holding part. The thinning devices are symmetrically disposed on the sides of the two carrier boxes. A liquid storage box is disposed on the side of the holding part. The spraying device is disposed on the side of the carrier box and located above the thinning device. The spraying device is connected to the liquid storage box.

[0005] In the above manner, the top of the scissor-shaped grip is connected to two thinning devices via a carrier box. By operating the grip, the distance between the thinning devices can be controlled. By placing the grape branch between the two thinning devices, the grape branch can be pruned. At the same time, the spraying device can spray a bactericidal liquid to sterilize the pruned grape branch.

[0006] Furthermore, the spraying device includes: a nozzle, a hose, and an adjusting device. A groove is provided on the top of the carrier box, the adjusting device is slidably connected to the groove, the nozzle is mounted on the adjusting device, and the nozzle is connected to the liquid storage box through the hose.

[0007] Furthermore, the adjustment device includes: a slider, a fixed frame, and a slot. The slider has a double-layer circular structure with an I-shaped cross-section. The fixed frame is fixed to the upper part of the slider. The slider is slidably connected in the groove. The inner wall of the end of the fixed frame is provided with an arc-shaped slot, and the nozzle is engaged in the slot.

[0008] In this way, a miniature liquid pump is installed inside the storage tank to deliver the disinfectant solution to the nozzle for spraying through a hose. The slider can rotate and slide in the slot, thereby adjusting the position and orientation of the nozzle. The fixing frame is made of a tough plastic material, which can insert the nozzle and then lock it into the slot.

[0009] Furthermore, the gripping part also includes: a handle, a connecting arm, and a control button. There are two handles and two connecting arms. The connecting arm is provided at the top of the handle. The liquid storage box is provided on the side of one of the handles. The connecting arm is slidably connected to the carrier box. The control button is signal connected to the flower thinning device and the spraying device.

[0010] Furthermore, it also includes a telescopic device, which is disposed on the carrier box and connected to the connecting arm.

[0011] Furthermore, the telescopic device includes a handwheel, a main shaft, and a gear. One end of the main shaft is rotatably connected to the carrier box, and the other end passes through the carrier box and is fixedly connected to the handwheel. The gear is mounted on the main shaft. The connecting arm is placed inside the carrier box and has a gear rack on its side. The gear is connected to the connecting arm through the gear rack. A stop is provided on the inner wall of the carrier box. A limit groove is formed on the inner side of the connecting arm, and the stop is placed in the limit groove.

[0012] In this way, when the grape branches are too high and the workers cannot hold the device on the branches, they can turn the handwheel to drive the carrier box to raise the thinning device, thereby increasing the overall length of the device and allowing for the pruning of branches at higher elevations.

[0013] Furthermore, the flower thinning device includes: a flower thinning roller, protrusions, a protective cover, and a motor. The motor is located inside the carrier box. The flower thinning roller is located on the side of the carrier box and connected to the motor. The outer surface of the flower thinning roller is provided with a plurality of protrusions. The protective cover has a semi-circular structure and is fixedly connected to the carrier box and located on the side of the flower thinning roller. The protective cover faces inward.

[0014] Furthermore, the carrier box is provided with several heat dissipation holes.

[0015] In summary, this utility model has the following advantages and beneficial technical effects: 1. This utility model provides a grape flower thinner that can more conveniently prune excess flower clusters on grape branches, preventing them from affecting the quality of the grapes that subsequently form. 2. The grape thinning device of this utility model has a fungicide spraying device for the pruned branches, which is beneficial to the protection of the branches and at the same time plays a pretreatment role in the subsequent fruit thinning step. 3. The grape thinning device of this utility model has an adjustment device that can adjust the overall length, which can make the overall length longer, which is beneficial for pruning the branches that are higher.
