Description

TECHNICAL FIELD

[0001] The utility model relates to the field of special tools for agricultural production, in particular to an electric fruit and flower thinning device. BACKGROUND

[0002] Fruit thinning refers to the process of removing a portion of the fruits or flowers that grow too densely, are too weak, or are in an inappropriate location during the cultivation of fruit trees to ensure the quality and yield of the fruits. This measure helps to concentrate the nutrients of the fruit trees for the remaining fruits, thereby improving the quality and fruit setting rate of the fruits. For example, in the process of existing greenhouse grape cultivation, in addition to normal fertilization and pest management, flower and fruit thinning of grapevines is a high-quality cultivation technique to ensure the external and internal quality of grape fruits.

[0003] CN201839663U discloses a grape flower and fruit thinning device, which includes a U-shaped handle, rubber pads connected to the two ends of the U-shaped handle, and tooth heads on the rubber pads. The tooth heads on the two rubber pads are oppositely arranged inward. The tooth heads have a plurality of small teeth. During the process of grape flower and fruit thinning, the small flowers (small berries) are removed by the intersecting tooth heads to achieve the purpose of flower and fruit thinning.

[0004] CN215011828U discloses a thumb pressing type grape flower and fruit thinning device, which includes an upper shear body and a lower shear body. The upper shear body includes a handle one and an arc-shaped bulging block one on the upper half of the handle one. The front end of the bulging block one is provided with a semicircular notch one. The lower shear body includes a handle two and an arc-shaped bulging block two under the front end of the handle two. The front end of the bulging block two is provided with a semicircular notch two corresponding to the semicircular notch one. The cut grape grains fall out of a cylindrical through hole formed by the combination of the semicircular notch one and the semicircular notch two.

[0005] In the existing greenhouse grape thinning technology, the number of remaining fruits or flowers cannot be effectively controlled during fruit and flower thinning, resulting in an insignificant fruit and flower thinning effect. For example, when thinning grape clusters, it is best to leave 3-5 grape grains on the small branches of the clusters. Too many grape grains are not conducive to the growth of fruits, and too few grape grains result in poor economic benefits. In addition, manual flower and fruit thinning devices have low efficiency and high labor intensity. Therefore, an electric tool is needed to perform flower and fruit thinning to reduce the labor intensity of the operator and improve labor efficiency. At the same time, the number of remaining fruits or flowers can be controlled by reasonably arranging the tooth heads of the roller to improve the economic benefits of crops. SUMMARY

[0050] The soft cylinder sleeve 54 is provided with an upper tooth row 541 and a lower tooth row 542, in order to prevent all flowers or fruit clusters from being removed by the roller 5, a gap is arranged between the upper tooth row 541 and the lower tooth row 542, and no tooth head 50 is arranged in the area of the gap; a plurality of first tooth rows 551 and a plurality of second tooth rows 552 are alternately arranged on the upper tooth row 541 and the lower tooth row 542, and the first tooth row 551 and the second tooth row 552 are both composed of a plurality of tooth heads 50 arranged in the axial direction; the tooth heads 50 of the first tooth row 551 and the second tooth row 552 are staggered. When the fruit and vegetable flower thinning device is used, the branch with fruit clusters or flower clusters passes between the two rollers 5, the main branch of the fruit cluster or the flower cluster passes through the gap area between the upper tooth row 541 and the lower tooth row 542, and the fruit cluster or the flower cluster passes between the tooth heads 50 of the two rollers 5, and the small fruit particles or small flowers are removed by the staggered tooth heads 50, so as to achieve the purpose of fruit thinning or flower thinning; wherein the number of tooth heads 50 of the first tooth row 551 and the second tooth row 552 is different, and the positions of the tooth heads 50 of the two are not aligned in an alternating arrangement, as shown in the figure, the first tooth row 551 is composed of four tooth heads 50 arranged in the axial direction, the second tooth row 552 is composed of three tooth heads 50 arranged in the axial direction, and the tooth head 50 of the second tooth row 552 is opposite to the gap of the tooth head 50 of a tooth row 551, so that the tooth heads 50 of the first tooth row 551 and the second tooth row 552 are staggered, thereby effectively removing the small fruit particles (small flowers) on the fruit cluster (flower cluster). Figure 5

[0051] ​Further, in order to uniformly remove small fruit grains (small flowers) on the fruit cluster (flower cluster), so that the final small fruit grains (small flowers) left on the fruit cluster (flower cluster) are neither too dense nor too few, the spacing of each tooth head 50 and the shape of the tooth head 50 need to be reasonably configured; for example, when thinning the grape fruit cluster, in order to leave 3-5 fruit grains on each small branch of the fruit cluster, the distance between the upper tooth row 541 and the lower tooth row 542 is set to 9-12 mm; the axial spacing A of the adjacent two tooth heads 50 is 5-6.5 mm.

[0052] At the same time, the shape of the tooth head 50 needs to be set as a taper, and the tooth base width b is set to 3.2-4.5 mm; the tooth height h of the tooth head 50 is set to 2.0-4.0 mm; in order to prevent the tooth head 50 from scratching the fruit grains of the plant, chamfers are provided at the tooth top and the tooth base, wherein the tooth top chamfer radius of the tooth head 50 is 0.5-1.2 mm, and the tooth base chamfer radius is less than or equal to 1.0 mm; the tooth top straight line segment distance d is 0-0.5 mm; when the tooth top straight line segment distance d of the tooth head 50 is zero, the top end of the tooth head 50 is a spherical surface, and the spherical surface has the same force on the fruit cluster at each angle, which can effectively avoid scratching the plant during thinning, and therefore has a good thinning effect.

[0053] Further, in order to control the number of fruit or flowers left on the fruit cluster or flower cluster of different plant varieties, an adjusting knob 1 is arranged between the first base body 10 and the second base body 20, which is used to flexibly adjust the spacing between the two rollers 5; for smaller flowers / fruit clusters, the spacing between the two rollers 5 is smaller; for larger flowers / fruit clusters, the spacing between the two rollers 5 is larger. For example, Figure 2, 7-9, the adjusting knob 1 is fixedly connected with the second base 20 and slidably connected with the first base 10, by changing the position of the adjusting knob 1 on the second base 20, the rotating stroke of the first base 10 relative to the second base 20 is adjusted, and then the opening size between the first jaw arm 2 and the second jaw arm 4 is adjusted. Specifically, a first arc-shaped hole 101 is formed on the first base 10, and a second arc-shaped hole 201 is formed at the corresponding position of the second base 20, and the adjusting knob 1 passes through the first arc-shaped hole 101 and the second arc-shaped hole 201; the adjusting knob 1 sequentially includes a knob head 11, a limiting disc 12 and an adjusting stud 13 from top to bottom, the limiting disc 12 is slidably connected with the first arc-shaped hole 101, and the adjusting stud 13 is threadedly connected with an adjusting nut 14 after passing through the second arc-shaped hole 201, by tightening the adjusting stud 13, the adjusting knob 1 is fixed on the second base 20; when it is needed to change the position of the adjusting knob 1, the knob head 11 is rotated by fingers to loosen the adjusting knob 1, and the adjusting stud 13 can move in the second arc-shaped hole 201, when the adjusting stud 13 moves to the uppermost position of the second arc-shaped hole 201, at this time, the first jaw arm 2 and the second jaw arm 4 cannot be completely closed, and the opening distance between them is the largest, and the electric fruit and flower thinning device can be used for thinning flowers and fruits of larger flowers / fruit clusters;

[0054] When the adjusting stud 13 moves to the lowermost position of the second arc-shaped hole 201, at this time, the first jaw arm 2 and the second jaw arm 4 can be completely closed, and the opening distance between them is the smallest, and the electric fruit and flower thinning device can be used for thinning flowers and fruits of smaller flowers / fruit clusters;

[0055] Further, by setting the adjusting knob 1, the distance between the two rollers 5 can be flexibly adjusted according to different plant varieties and the size of flowers and fruit clusters, so as to control the number of fruits or flowers left on fruit clusters or flower clusters of different plant varieties;

[0056] Further, a spring 7 is arranged between the first handle 3 and the second handle 6, the spring 7 is a compression spring, and can provide elastic potential energy for the first handle 3 and the second handle 6 to be opened, and under the action of the spring 7, the first handle 3 and the second handle 6 can be automatically opened after each fruit / thinning operation is completed.

[0057] As Figure 7As shown, further, in order not to continuously press the first handle 3 and the second handle 6 during thinning, a locking block 9 is rotatably connected to the first base 10, and a locking notch 202 is formed in the second base 20, the locking block 9 can be inserted into the locking notch 202, at this time, the first handle 3 and the second handle 6 cannot be automatically opened under the action of the spring 7, preventing the first handle 3 and the second handle 6 from being automatically opened due to incomplete thinning, the locking block 9 is further provided with a torsion spring, the torsion spring applies a tendency force to the locking block 9 inserted into the locking notch 202, during thinning, the operator presses the first handle 3 and the second handle 6, when the first jaw arm 2 and the second jaw arm 4 are closed in place, the locking block 9 is automatically inserted into the locking notch 202, at this time, the first handle 3 and the second handle 6 will not be automatically opened without continuously pressing the first handle 3 and the second handle 6; after the current thinning operation is completed, the locking block 9 is pulled away by the finger, and the locking block 9 is removed from the locking notch 202, at this time, the first handle 3 and the second handle 6 can be automatically opened under the action of the spring 7, preparing for the next thinning operation.

[0058] Working principle

[0059] Firstly, the plant to be thinned is located in the opened first jaw arm 2 and the second jaw arm 4, the first handle 3 and the second handle 6 are pressed by hand, the first jaw arm 2 and the second jaw arm 4 are closed, the plant passes through the two rollers 5, when the first jaw arm 2 and the second jaw arm 4 are closed in place, the locking block 9 is automatically inserted into the locking notch 202, at this time, the first handle 3 and the second handle 6 will not be automatically opened without continuously pressing the first handle 3 and the second handle 6; then, the motor 44 switch is turned on, the two rollers 5 rotate, and the flower spikes or fruiting branches passing through the rollers 5 are shaken off a part during the pulling of the electric thinning device;

[0060] When the number of fruit grains or small flowers left on the fruiting branches or flower spikes is too large, the first jaw arm 2 and the second jaw arm 4 are closed by adjusting the knob head 11 to reduce the opening, and the spacing between the two rollers 5 is reduced to increase the thinning amount; when the number of fruit grains or small flowers left on the fruiting branches or flower spikes is too small, the first jaw arm 2 and the second jaw arm 4 are closed by adjusting the knob head 11 to increase the opening, and the spacing between the two rollers 5 is increased to reduce the thinning amount, so that the thinning amount is finally within a reasonable range. After the current thinning operation is completed, the locking block 9 is pulled away by the finger, and the locking block 9 is removed from the locking notch 202, at this time, the first handle 3 and the second handle 6 are automatically opened under the action of the spring 7, preparing for the next thinning operation.
