Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural planting technology, and in particular relates to a fingertip pressing type fruit thinning device. Background Technology
[0002] Pinching and thinning flowers and fruits are crucial steps in agricultural planting. Firstly, thinning improves fruit quality by concentrating the plant's (vegetables, fruit trees, etc.) nutrients on the remaining fruit. Secondly, proper thinning prevents excessive nutrient consumption, maintaining healthy growth and promoting flower bud differentiation. It also ensures the fruit tree continues to flower and bear fruit in subsequent years, achieving stable yields year after year. Furthermore, excessive flowers and fruits put significant stress on the branches. Removing excess flowers and fruits reduces this burden, creating a more balanced tree structure and improving ventilation and light penetration. Good ventilation and light penetration effectively reduce pests and diseases, promoting healthy tree growth.
[0003] In actual production, individual growers or small-scale plantation growers usually use their fingers or scissors to pinch off the tips or thin out flowers and fruits. Long-term work will damage the fingers and is very inefficient. Using scissors often causes damage to the plant stems and vines around the flowers and fruits by squeezing them during the pruning process, which can lead to diseases and pests. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] A typical embodiment of this utility model is as follows: Figures 1-4 As shown, a fingertip-pressing fruit thinner includes a pressure plate 1 and a support plate 4. One end of the pressure plate 1 is rotatably connected to the support plate 4 via a rotating shaft 8, allowing the pressure plate 1 to rotate around the support plate 4. A helical spring 3 is sleeved on the rotating shaft 8, with one end of the helical spring 3 fixedly connected to the pressure plate 1 and the other end fixedly connected to the support plate 4. The helical spring 3 allows the pressure plate 1 and the support plate 4 to form a set angle. In use, pressing the end of the pressure plate 1 away from the rotating shaft 8 causes the pressure plate 1 to rotate around the rotating shaft 8, bringing it closer to the support plate 4. When the pressure plate 1 is released, under the elastic force of the helical spring 3, the pressure plate 1 rotates counterclockwise, moving it away from the support plate 4. By incorporating the helical spring 3, the pressure plate 1 can be quickly reset for the next cut, improving work efficiency.
[0027] The lower surface of the pressure plate 1 is provided with a blade 7. The blade 7 is made of stainless steel and can quickly cut off flower stems and fruit stalks. The blade 7 is set perpendicular to the pressure plate 1, and the cutting edge of the blade 7 faces the support plate 4. The upper surface of the support plate 4 is provided with a knife groove 9, which is adapted to the blade 7. When the pressure plate 1 is pressed and moves towards the support plate 4, the blade 7 can enter the knife groove 9, thereby preventing the blade 7 from affecting the rotation of the pressure plate 1. In use, place the flower stems and fruit stalks between the pressure plate 1 and the support plate 4, press the pressure plate 1, and use the blade 7 to cut the flower stems and fruit stalks.
[0028] Furthermore, to prevent accidental injury to people or scratches to tree branches, the tip of the blade is blunted.
[0029] A finger sleeve rubber band 2 is provided on the top surface of the pressure plate 1 away from the rotating shaft 8. The operator can put their index finger into the finger sleeve rubber band 2 to fix it on the operator's hand. The finger sleeve rubber band 2 is made of rubber and is elastic, which can adapt to index fingers of different sizes. A groove 5 is opened on the lower surface of the support plate 4. The inner surface of the groove 5 is arc-shaped and fits the operator's thumb. When using it, the operator puts their thumb into the groove 5 to support the support plate 4. The operator completes the cutting by coordinating the index finger and thumb.
[0030] After use, the closed pressure plate 1 and the support plate 4 can be tied together using the finger elastic band 2, so that the blade 7 is stored in the blade groove 9, preventing the blade from being exposed and causing danger.
[0031] Furthermore, a rubber pad is provided on the inner surface of the groove 5 to fix the thumb and prevent the fingers from slipping during work, thereby improving the stability during work and avoiding safety hazards.
[0032] A long rod hook 6 is provided on the front side of the tray 4. The long rod hook 6 is detachably connected to the tray 4. Specifically, the long rod hook 6 includes a connecting rod, with hooks at both ends. A mounting hole 10 is provided on the front side of the tray 4 along its width direction. The mounting hole 10 is adapted to the connecting rod. A rubber sleeve is fitted on the outside of the connecting rod, and the connection between the connecting rod and the mounting hole 10 is achieved through the rubber sleeve. Figure 3 As shown, by setting a long pole hook 6 on the front side of the tray 4, it can be used to hang net bags or bags, which can collect the cut parts in time when thinning flowers, thinning fruits and removing tips, reduce the workflow of collecting and picking up withered flowers, leaves and weak fruits in the later stage, and further improve work efficiency.
[0033] When it is not necessary to recycle the cut plants, the long hook 6 can be pulled out from the mounting hole 10 to avoid the hook getting caught on the plants and causing damage.
[0034] Working principle
[0035] When in use, insert your index finger into the elastic band of the finger sleeve, and fix your thumb in the groove at the bottom of the support plate. By pressing with the combination of your index finger and thumb, the fruit thinner works by pressing with your fingertips. The spiral spring makes it rebound quickly after each press.
[0036] The long pole hook is fixed to the tray with a rubber membrane, and the bag is fixed to the wrist with the long pole hook, which is used to collect the cut flowers and fruits in time.
[0037] When finishing work, keep the plate closed and use finger cots and rubber bands to bind the pressure plate and support plate to avoid the safety hazard of the blade opening and closing.
[0038] This invention allows for the one-time removal of the target part by gently pressing with the index finger, ensuring accurate positioning without damaging surrounding plant tissues. It can be applied to thinning flowers, thinning fruits, and topping, improving work efficiency.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
