Description

Technical Field

[0001] The utility model relates to the technical field of special tools for agricultural production, and particularly relates to a grape flower bud thinning clip. Background Art

[0002] Grape fruit thinning is an important link in grape cultivation management. It involves removing some fruit grains or flower buds on the flower clusters to improve the growth environment of the remaining fruit grains, and to increase the size, quality and commercial value of the fruits. Fruit thinning can reduce the occurrence of diseases and pests, promote uniform ripening of fruit grains, improve the photosynthesis efficiency, thereby increasing the yield and improving the overall appearance of grapes.

[0003] However, in current production, scissors are generally used for flower and fruit thinning. There are hundreds of small flowers in a grape inflorescence, and more than half of them need to be cut off, which is time-consuming and laborious. Especially for varieties with tight flower clusters, it affects the popularization of this high-quality cultivation technology of flower and fruit thinning, and also restricts the popularization of grape varieties with compact flower clusters in production. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a grape flower bud thinning clip that can save the time and effort of fruit thinning.

[0005] To achieve the above technical purpose, the utility model proposes the following technical solution: A grape flower bud thinning clip includes elastic clip arms with a V-shaped structure. The open ends of the elastic clip arms are both connected with clip heads through handle rods. The handle rods and the clip heads are of an integral structure. On the inner walls of the two clip heads on the elastic clip arms, there are several comb teeth provided. The comb teeth on the two clip heads are arranged oppositely. On one side of the inner wall of the handle rod near the clip head end, there is a first stop post provided. On the outer side wall of the handle rod, there are several linear protrusions corresponding to the first stop post. The two first stop posts are opposite and staggered. A through hole is provided on the clip head.

[0006] Further, a clamping groove is provided at the end of the handle rod away from the clip head, and the end of the elastic clip arm is arranged in the clamping groove.

[0007] Further, a second stop post is provided on the inner wall of the handle rod and below the first stop post. The height of the second stop post is lower than that of the first stop post.

[0008] Further, several dot-shaped protrusions corresponding to the second stop post are provided on the outer side wall of the handle rod and below the linear protrusions.

[0009] Further, the number of the through holes is three. The inner diameters of the three through holes are different and are all between 2 - 2.5 mm.

[0010] Further, a retaining pin is provided on the outer side wall of any one of the handle rods. An elastic cord is connected to the retaining pin. One end of the elastic cord is provided with a buckle cooperating with the retaining pin.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model drives the opening and closing of the chuck through the elastic clamping arms, and the comb teeth perform the operation of thinning the flower buds on the flower spike. Compared with using scissors for removal, the working efficiency is greatly improved, and it is also more convenient and labor-saving to use; through the first stop post and the second stop post, the size of the opening of the chuck is determined to prevent the opening from being too large or too small due to poor force control during thinning, resulting in too much or too little flower buds being combed off, affecting the thinning effect; through the setting of the through hole, the maturity period of the flower spike can be judged, avoiding damage to the flower spike caused by thinning the fruit too early or too late.

[0014] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model will be further described in conjunction with the drawings, but the present utility model is not limited to these embodiments.

[0015] As Figure 1 shown, the present utility model provides a grape flower bud thinning clip, which includes elastic clamping arms 1 with a V-shaped structure. The open ends of the elastic clamping arms 1 are each connected to a chuck 3 through a handle rod 2. The handle rod 2 and the chuck 3 are of an integral structure. A plurality of comb teeth 4 are provided on the inner walls of the two chucks 3 on the elastic clamping arms 1. The comb teeth 4 on the two chucks 3 are arranged oppositely. On one side of the inner wall of the handle rod 2 near one end of the chuck 3, a first stop post 5 is provided. A plurality of linear protrusions 6 corresponding to the first stop post 5 are provided on the outer side wall of the handle rod 2. The two first stop posts 5 are opposite and staggered. A through hole 7 is opened on the chuck 3.

[0016] As Figure 1As shown, by the opening and closing of the elastic clamping arms 1, the opening and closing of the chuck 3 is realized. The comb teeth 4 clamp the flower spike and scrape off the grape flower buds downward. During the fruit thinning process, the first retaining posts 5 respectively abut against the opposite handle rods 2. Through the interaction of the first retaining posts 5 on the two handle rods 2, the size of the opening of the chuck 3 can be controlled to prevent the opening of the chuck 3 from being too small due to poor control of the force during the combing of the flower buds, resulting in excessive amount of grape flower buds being combed off. The linear protrusion 6 is used to increase the friction between the hand and the handle rod 2; the scraped flower bud part can flow out from the through hole 7. The size of the through hole 7 can be compared with the size of the flower bud to judge the maturity period of the flower spike. At the same time, the clip proposed by the present utility model can also be applied to the later thinning work of small grape fruits. Compared with using scissors to remove in the prior art, it is convenient to use, time-saving and labor-saving, and greatly improves the work efficiency.

[0017] A clamping groove 8 is provided at one end of the handle rod 2 away from the chuck 3, and the end of the elastic clamping arm 1 is arranged in the clamping groove 8.

[0018] As Figure 1 shown, the elastic clamping arm 1 and the handle rod 2 are detachably connected through the clamping groove 8. On the one hand, during use, if the chuck 3 or the elastic clamping arm 1 is damaged, the damaged part can be replaced and continue to be used. On the other hand, it is convenient to make an injection mold according to the structures of the chuck 3 and the handle rod 2 to achieve mass production.

[0019] A second retaining post 9 is provided on the inner wall of the handle rod 2 and at the end of the first retaining post 5 away from the chuck 3, and the height of the second retaining post 9 is lower than that of the first retaining post 5.

[0020] As Figure 1 shown, the height of the second retaining post 9 is lower than that of the first retaining post 5, which can further control the opening angle of the chuck. The second retaining posts 9 respectively abut against the opposite handle rods 2, making the opening of the chuck 3 larger than that of the first retaining post 5, so as to be applicable to grapes with larger flower spikes. In this embodiment, the first retaining post 5 and the second retaining post 9 form two gears for controlling the opening size of the chuck 3.

[0021] A plurality of dot-like protrusions 10 corresponding to the second retaining post 9 are provided on the outer wall of the handle rod 2 and below the linear protrusion 6.

[0022] As Figure 1 shown, the dot-like protrusions 10 are used to increase the friction between the hand and the handle rod 2 on the one hand, and on the other hand, to remind the user of the position where the hand is placed according to the size of the grape flower spike.

[0023] The number of the through holes 7 is three, and the inner diameters of the three through holes 7 are different and are all between 2 - 2.5 mm.

[0024] As Figure 1As shown, during the period of floret separation, 10 - 15 days before blooming, the size of the flower bud is 2 - 2.5 mm, and the sizes of the three through - holes 7 are 2.0 mm, 2.2 mm, and 2.5 mm respectively. The maturity period of the flower spike is distinguished according to the size of the holes.

[0025] A retaining pin 11 is provided on the outer side wall of any one of the handle rods 2, an elastic cord 12 is fixedly connected to the retaining pin 11, and a buckle 13 that cooperates with the retaining pin 11 is provided at one end of the elastic cord 12.

[0026] As Figure 1 As shown, through the settings of the retaining pin 11, the elastic cord 12, and the buckle 13, the flower - bud thinning clip can be contracted, which is convenient for storage; the elastic cord 12 winds the two handle rods 2 together, and inserts the buckle 13 into the retaining pin 11 for fixation. When in use, just open the buckle 13. When in use, to prevent the elastic cord 12 from getting in the way, the elastic cord 12 can be wound around the handle rod 2 with the retaining pin 11. After winding, insert the buckle 13 into the retaining pin 11 for fixation, which will not affect normal use.

[0027] Principle of use: The utility model is applicable to Kyoho grapes, Shine Muscat grapes, and Summer Black grapes. It is used during the period of grape floret separation, 10 - 15 days before blooming. Since the flower spike is soft and prone to wounds, and the branch stalks are also easy to fall off, the thinning period should not be too early. If it is too early, the fruit shape may not be beautiful. If the thinning is too late, the comb teeth 4 are easily stuck by the branch stalks, and the branch stalks will be cut off together during the thinning process, and the thinning efficiency is low and the effect decreases. By comparing the size of the through - hole 7 with the size of the flower bud, it is judged whether fruit thinning can be carried out;

[0028] When in use, first open the buckle 13, and wind the 12 around the handle rod 2 with the retaining pin 11. After winding, insert the buckle 13 into the retaining pin 11 for fixation. Hold one handle rod 2 with one hand and pinch the stalk part of the flower spike with the other hand. The clamping head 3 gently clamps the position about 5 cm from the front end of the flower spike. According to the size of the flower spike, determine the opening size of the clamping head 3 to determine the gear position of the finger on the handle rod 2. Repeat gently clamping 2 - 3 times from top to bottom to scrape off the flower buds, and comb the over - dense flower spike. Use the intersecting comb teeth 4 to comb off the flower buds to achieve the purpose of fruit thinning. For the grape flower spike, implement one new shoot - one flower spike. Finally, leave the length of the flower spike about 3.5 cm, gently comb the tip, and retain 50 - 55 flower buds at the tip as the standard. After use, open the elastic cord 12 wound around one handle rod 2, then the elastic cord 12 winds the two handle rods 2 together, and inserts the buckle 13 into the retaining pin 11 for fixation.

[0029] The specific embodiments described herein are merely illustrative of the spirit of the utility model. Those skilled in the technical field to which the utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the utility model or exceed the scope defined by the appended claims.
