Install base 12 on bottom plate 11, install respectively in base 12 both sides left branch vaulting pole 13's rear end and right branch vaulting pole 14's rear end, here, left branch vaulting pole 13 and right branch vaulting pole 14 can fixed mounting in base 12 both sides, also can be through multiple modes movable mounting such as stop pin, draw-in groove with base 12 both sides, make left branch vaulting pole 1 and right branch vaulting pole 14 can lean forward on base 12, as shown in fig. 2, be about to stretch into the plant before the toper rotator 15, its anteversion angle is adjusted according to the drop of plant can.
The top of toper rotator 15 is installed at the front end of left branch vaulting pole 13, the bottom of toper rotator 15 is installed at the front end of right branch vaulting pole 14 and toper rotator 15 and left branch vaulting pole 13, right branch vaulting pole 14 all constitutes normal running fit, its normal running fit mode can adopt the multiple mode among the prior art, on the top of toper rotator 15, bottom center department all adopts the round pin axle to install on left branch vaulting pole 13 or right branch vaulting pole 14, or the center department of toper rotator 15 sets up the axis and runs through its top and bottom central point, the axis is utilized the bearing to install at left branch vaulting pole 13 and right branch vaulting pole 14, make toper rotator 15 can rotate on left branch vaulting pole 13 and right branch vaulting pole 14.
The combing strip 16 is spirally wound on the conical rotating body 15, and a plurality of combing teeth 17 are arranged on the combing strip 16. The comb teeth 17 on the comb-brush strip 16 are designed by the taper of the taper-shaped rotating body 15, so that the fruits at different positions (depths) of the plant can be harvested and covered on the premise of not adjusting the position of the bottom plate 11.
The spirally wound installation state of the comb-brush strip 16 on the conical rotating body 15 is left-handed, i.e. counterclockwise, with the direction from the bottom surface to the top end of the conical rotating body 15 as a reference; and conical rotating body 15 is the clockwise motion based on bottom surface to top visual angle under power component's effect, and the anticlockwise design of comb brush strip 16, conical rotating body 15's clockwise rotation are passed through here, form the power of two different directions, a direction of straight line, a direction of rotation promptly, to in the fruit, formed a clamping effect (direction of rotation realization), a dragging effect (direction of straight line realization), thereby gather the fruit, and realize high clean rate.
The output end of the power assembly is installed on the conical rotating body 15, and under the action of the power assembly, the conical rotating body 15 moves clockwise based on the viewing angle from the bottom surface to the top end so as to match the left-handed design of the spiral winding installation state on the conical rotating body 15.
The power assembly can be directly arranged on the left support rod 13 or the right support rod 14, and a motor with a small specification is adopted. In order to ensure certain power requirements and increase the reliability of the device, a power source device 18 is mounted on the bottom plate 11, and the power source device 18 may be a motor. The output shaft of the power source device 18 is provided with a chain wheel 19, the rear end of the right support rod 14 is provided with a transmission shaft 10, a transmission chain 21 is arranged on the chain wheel 19 and the transmission shaft 10, and the power source device 18 can drive the transmission shaft 10 to rotate through the chain wheel 19 and the transmission chain 21. Meanwhile, a conventional chain transmission assembly, such as a chain, a transmission chain, etc., is installed between the bottom of the conical rotating body 15 and the transmission shaft 10, so that the transmission shaft 10 can drive the conical rotating body 15 to rotate. In practical application, based on the angle from the chain wheel 19 to the power source device 18, the power source device 18 drives the chain wheel 19 to move clockwise, so that the conical rotating body 15 can be ensured to move clockwise based on the angle from the bottom surface to the top end; similarly, the power source device 18 may be adjusted by using a steering gear or other prior art to ensure that the conical rotating body 15 moves clockwise from the bottom to the top.
In order to avoid the conical rotating body 15 from extending into the plant and damage to the plant by the left supporting rod 13 and the right supporting rod 14, the left supporting rod 13 and the right supporting rod 14 can be both cylindrical or wedge-shaped, so as to reduce the influence of the left supporting rod 13 and the right supporting rod 14 on the plant. Similarly, a protection plate 20 can be installed at the side end of the right support bar 14, and the link transmission assembly is located between the protection plate 20 and the right support bar 14 to prevent the link transmission assembly from damaging the plant during operation.
In order to protect the fruits when harvesting, the comb teeth 17 can be made of silica gel, and meanwhile, the comb teeth 17 can be coated with sugar-dredging hydrophobic materials, so that the adhesion of the liquid flowing out of the fruits can be reduced, and the work in rainy days can be guaranteed. Meanwhile, the comb-brushing teeth 17 can be arranged on the comb-brushing strip 16 in an equal distribution manner, and the width between the adjacent comb-brushing teeth 17 is smaller than that of the harvested goods, so that the harvested goods (fruits) can be clamped by the adjacent comb-brushing teeth 17.
In actual use, as shown in fig. 2, the power source device 18 operates to drive the transmission shaft 10 to rotate through the sprocket 19 and the transmission chain 21, and the transmission shaft 10 drives the conical rotating body 15 to rotate through the link transmission assembly. The comb-brushing strips 16 and the comb-brushing teeth 17 on the conical rotating body 15 go deep into the plant at a certain speed, so that the comb-brushing teeth 17 are fully contacted with the plant, and the areas of the plant fruits contacted with the comb-brushing teeth 17 on different conical sections are different, so that the harvesting range of each position area of the plant is met. Then, due to the anticlockwise design of the combing strips 16 and the clockwise rotation of the conical rotating body 15, two forces (a straight direction and a rotating direction) in different directions are formed, and the clamping and pulling effects on the fruits are formed, so that the fruits are harvested, and the high harvest rate is realized.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
